    Hi guys,

    Seems that the Amoi section is looking a bit dull.

    I’ve recently purchased a Amoi N820, or some people call it “Amoi N820 Big V’.

    Andi’s done a review of this as well, and I thought that when I received mine, I could answer any questions that anyone would have too.

    Good luck to all you enthusiasts :)

    Hey how_1, thanks for opening this section.

    I’ve received my Amoi N820 today. I will share my thoughts with you once I have had a play with it. I got my device through Etotalk and I must say that the service was great. They updated me at each stage of the purchase (processing, address confirmation, dispatch, ect). If the device works accordingly I will post some feedback in the seller section.

    Will report back on my thoughts soon.

    Amoi, Big V, N820, review initial thoughts on my new phone.

    I’ve had the Amoi N820 (Big V) in my ownership for 1 day now. It should be noted that my thoughts are based upon my experience using a custom ICS firmware (ROM) provided by the seller, Etotalk. During the review I will compare my user experience with that of my last Android phone, a HTC Desire (running ICS).

    Opening the box, how does it look and feel?

    I have to say that I have been pleasantly surprised at the quality of the Big V. Going on my previous (and dated) experience of Chinese made tablets and phones I half expected a flimsy phone which would need to be handled with care. While the back of the phone is clearly made from plastic, it feels solid and doesn’t flex when pressure is applied, as my old ZTE Blade used to do. For what is effectively a budget device, this phone feels very soundly made. It is not luxurious, yet it doesn’t feel like it is cheap.

    Overall I’m pleased with the look, build quality and size of the phone. A couple of my colleagues have already made positive remarks about the Big V, with one suggesting that it looked like a good marriage of HTC and Samsung design. I personally feel that the, 4.5″ screen feels the right size on this phone. I could imagine a 5″ screen device being cumbersome for one-handed use.

    What’s the performance like?

    I expected some lag, but I have to say that none has been forthcoming so far. This is a sprightly device compared to my Desire.

    You can feel the dual-core and 1gb RAM of the Big V put to decent use. I wasn’t a massive fan of the strange Xperia styled home launcher provided by Etotalk so I switched to my favourite launcher, Apex. As stated before, my review is based upon the Etotalk Custom firmware so I can’t give you an opinion on how it performs straight from Amoi. What I can say is that it handles apps such as Netflix, Spotify and TvCatchup perfectly. I have only tried a couple of games so far (Tiger Woods Golf 2012 and Where’s My Perry), and I have no problems to report. I’m quite impressed by this phone, it feels pretty smooth to the user.

    A minor quibble is that the screen could be a bit more sensitive to the touch, but this is something that I have improved using an app from the Play Market. Some people may find issue with the N820 being a tad heavier than a lot of other new phones. I think this due to the large battery of the Big V. I personally feel that the little bit of weight adds to the sturdy feel of the device.

    Does it take pictures?

    As I said previously, I have only been using the Amoi N820 for a day so I haven’t had many chances to take pictures or record video. However, I am pleased with the pictures I have taken so far. I can see the big difference the 8mp camera has made when I compare it to the quality of shots I got from the HTC Desire . I’ve had a quick look at the front facing 3mp camera and it looks like it could provide a decent image when using Skype video. I haven’t tried Skype yet, so I can’t comment on it’s functionality so far. Neither have I tried to record any video to date.

    Overall I am very pleased with my purchase so far. I will update this post as I discover new good or bad things about the phone. The Big V was meant to be an experiment in using the Chinese electronics market with a view on making further purchases in the future. At present it looks like I could be holding on to this phone long into 2013.

    Hi Darren,

    Looks like the Amoi N820 turned out to be a good buy for you.

    I also had the same idea as you – I experimented with Chinese phones in Christmas 2011 but found the HDC A9100 to be completely rubbish. Hence, now I’m trying out the supposedly-improved market of Chinese phones/tablets.

    It’s good to hear that the processing, memory and camera functions seem to be of acceptable quality.

    I have seem many pictures of the Amoi N820 live, and the back panel plastic does seem to look cheap but sturdy – will update this also when I receive mine. One thing that should differ between the two of our same models, is that apparently my supplier is sending me a factory direct model – without any Build modifications. Will also test out Skype, and more camera functions, and really put out some benchmark testing (if have the time).

    Hoping that around 1 week’s time, my Amoi N820 will be in my hands to inspect :)

    @Daisyhayseed: did you root your Amoi N820? If so, how did you do it, and how successful was it?


    P.S. Will do my review when finished tinkering around haha

  • #14520


    Just a quick few notes, as @Daisyhayseed has already covered most topics.

    Bought my N820 from thru UGoodBuy store.

    First impressions: Wow!!

    Seems like good build quality, and very nice finish. Nothing as nice as an iPhone 4’s metal rim and glass, but I was still impressed (since the price was only ~$206 USD).

    Speed was unexpectedly fast, seems MTK6577 can really be trusted. No lag either, showing that the 1gb RAM is helpful. Played only Angry Birds, so can’t really comment on the GPU, but it went smooth. Screen was very crisp, and I mean, I own an iPhone 4, and this 960 by 540 was actually good enough – you don’t really need a Retina. Wifi worked great, and tbh, iPhone 4’s 3.5″ just CANNOT compete with 4,5″ of Amoi’s. Got me thinking now of getting into the 5.3″ league.

    Phone didn’t come rooted, so Google Play wasn’t installed. Instead it came with the 360 Store (sorry, I am not completely fluent in Chinese). However, after hours of searching forums, and trying all sorts of different methods, I finally installed an updated Build of 6.0 with Play Store installed. So I’m all smiles.

    Final note: This Amoi N820 has gotten me pretty excited about what’s in store for us in the future. I mean, it’s cheap and it runs fairly well – dual SIM too, which I really want. And I can recommend Amoi N820 to ANYONE – so far, it’s great quality, and even the packaging box, etc. looked great. Also Antutu of ~5500 points.

    (If anyone needs a hand rooting this phone, just comment)

    what networks are you two using and how has the 3g been ?

  • #14548


    psilo110, I’m from the UK and I use the 3 Network. I haven’t had any problems with 3g connectivity. I use a lot of data through the Netflix app and Spotify and it has been good for me.

    Hey how_1, pleased to see that you received your Amoi safely. Even more pleased to see that you found a way to root it and install the Play market. Did you follow the advice on the XDA forums or did you find the rooting information somewhere else? I only ask as I understand that the”Big V” should have Jellybean available soon and I would be interested in upgrading but not without root functionality. As I said before, my device is running a Mod Rom provided by Etotalk. I found a way to access Clockwork Recovery, which has been useful to back up the current firmware. Now I have made a backup I’m eager to try out Jellybean.

    Now I have used the phone for a couple of weeks I have one small gripe to report. The GPS on my device seems to be broken. I don’t know whether this is a problem with the phone or with the Etotalk firmware. I’ve been experimenting with different GPS.conf files but with no luck. I don’t know whether this is a common issue with all N820’s? Still loving the device regardless, excellent value for money.


  • #14560


    @psilo110: I’m from New Zealand, and I’ve been using 2degrees and Vodafone networks. Tried the 3g on 2degrees, and it was amazingly fast – so I assume good 3g connectivity components.

    @daisyhayseed: Yes, I followed the instructions on XDA forums.

    Read the instructions and download info posts by user “Retteren”. I installed the latest 6.0 Build, and it came rooted, with Play Store.

    Me too, keen to try out 4.1 JB soon :) Will update on this, when it comes out, and if I am able to root it. I haven’t tested the GPS functions, but if I find any problems/fixes etc., I’ll update on that also.

  • #14585


    Can’t wait to receive my N820 now :) Jelly Bean on it’s way to it, easily achievable root, big screen, big battery!!! I am so happy I cancelled my Jiayu G3 order and got this.

    Have you heard about the new Amoi N821?!?!? IPS HD screen?!?


  • #14709



    I just received the N820 today.

    Great phone so far.
    Unfortunately I am new to Android (previous iPhone owner).
    Could you please explain how to root the phone?
    Does everything still work after rooting (I read some lost camera function)?

    Thank you!


  • #14712


    @Pounder: Follow this forum

    I am also an iPhone owner – but all OSs are similar. For me, everything worked; I think you lose the camera function if you flash Build 5.x onto Build 6.0 maybe?

    Read this forum and specifically, read “Retteren” posts:

    And also, copy the below link and download the package:

    This will give you Build 6.0 according to user “Retteren” instructions:

    0) Back up all data on cellphone, charge it to at least 60% battery, do not connect it to the PC yet, and TURN IT OFF. Plug in USB end of the USB – micro-USB cable into the PC.
    1) Unpack the RAR package
    2) Rename directory to remove all Chinese characters
    3) Unpack the N820_V6.0_ROOT_GMS.rar file (unpacks to N820_V6.0_ROOT_GMS).
    4) Go into the ‘USB驱动’ directory, unzip and install the USB VCOM driver.
    5) Go into the ‘刷机工具’ directory and double-click on the Flash_tool.exe file. Click on “Scatter-loading” and point to the N820_V6.0_ROOT_GMSMT6577_Android_scatter_emmc.txt .
    6) Hit F8 or click on ‘Firmware -> Upgrade’.
    7) Hold down the Volume Down button and connect the phone to the PC. The button can be released when the red bar starts moving.
    8) After “Firmware Upgraded” window shows, unplug phone, reboot, install and enjoy.


    Note: do this at your own risk, if anything screws up, don’t blame me :D.

    These steps worked fine for me, and everything works fine on my Amoi. There’s also Google Play now :)


  • #14726



    Thanks. Will do this this afternoon.
    What else will rooting give me?
    Can I get rid of the remaining Chinese language/functions still on the phone?


  • #14728



    Rooting gives you “superuser” functions. This means you can take full control of your phone.

    For example, you can installed root apps from Play Store. I installed one which allows me to control how fast the CPU runs.

    You can also install custom ROMs and there are many more things possible – sorry, I am more of a jailbreaker/unlocker haha, so I don’t know much about rooting. I only rooted to get Play Store working, and to control the CPU.

    You can get rid of the Chinese apps by going into the Settings, and uninstalling them.

  • #14729



    Thanks again.
    If I root, will I keep the Amoi “android” operating system, or will I have to install a new version (I suppose this is a ROM as well)?

    On my keyboard, I still have some Chinese signs. Can I turn that off?

    (sorry for the newby questions, but this is also my first China phone and I must say it rocks!)

    Thank you.

  • #14731



    It’s all good, no worries – this is what forums are for.

    The Build (ROM) you will be updating to is Build 6.0 . You may want to check what build you are currently on, just for interest. It’ll be in the Settings.

    When you update to Build 6.0 via those links, it’s still the same Android OS 4.0.4, but it’s been modified to be rooted, and have Play Store. The layout looks exactly the same.

    HOWEVER, the internal memory will change; forgot to tell you this. The initial internal memory was very low…but once updated, I think it goes up to 1.8GB? I’m not too sure about this, ‘cos I rely on micro SD cards.

    Yes you can turn that off, play around in the Settings section. There should be a Language and/or Keyboard option, where you un-tick the Chinese keyboard, and set the default keyboard as the normal Android one.

    Haha, not bad aye, Chinese phones these days do seem pretty awesome :)

  • #14965



    I downloaded the file from (took a day!), but the .rar is corrupt :-(
    Do you have another location to download the file from?


  • #14975



    Maybe, if you had the bandwidth and patience to download it once again? My broadband took only maybe 1 hour? Use a download manager possibly.

    My .rar was fine, is the .rar just not extracting properly?

    No, I think that’s the only good and easy one to try… I also tried 5.x rooting etc. from that referred German page, but that didn’t seem to work. And also the other links directed me to Build 6.0, but that’s without root capability.

    I am out of bandwidth, but will see if I can upload it somewhere to you after 4th November.


  • #15280


    I downloaded the file with no problems except low speed about 50 – 60 kb/s and did all the steps but now i got a problem with the rear camera.
    From what i read here , forum(dot)xda-developers(dot)com(slash)showthread.php?t=1846892 , the camera might be working again but they lost me here:
    Did you manage to get the rear camera back?
    I’ve tried several roms, but none have made the rear camera work again…
    Yes, with the referenced ROM everything is working, including the rear camera

  • #15484


    I’m new in the forum
    I just bought th amoi N821 and would like to update the rom
    I follow the instruction given by one of your member, but on the baidu page, it is said that “our site has moved up to Skydrive”.
    I know that skydrive is a site whre we can upload and download files, but I don’t khow how to access to it.
    Can you guys help me out ?

  • #15616


    Hello guys!
    I have also N821 and I would like to root it and install Play Store too. I think the package (roms) should be different for N821, or not?
    My phone says Android version: 4.0.4; Build number: N821_V2.1. What files I need to root and update rom?
    I guess this woulb be good start – – but my chinese is 0 and do not trust translator much…

  • #15667

  • #15700


    Thanks! I will go through the link you gave me. Were you able to finish the rooting of you N821 by that? What I want to achieve is update to JB and root then to be able to deinstall all chinese apps and correctly install all Google tools (store, mail, etc). Has your N821 also comes with 4.0.4 ICS or it was already JB?
    …this is my first android device, so I’m littlebit hasitating as I read everywhere about root/rom update could be dangerous and could brick your phone. I don’t want to brick my phone, it’s awesome!

  • #15727


    No, I have’nt received my Amoi yet.
    Orderes nov 6th and still waiting for it.
    Right now, I am looking for all possible way to root and update tehe rom.

  • #15733


    So same as me with only difference that I have my phone already. Do you think any of tools like cuold be usable with N821?
    Btw I was thinking about rooting – I can currently install all apps (i have apk file for), but several apps (like google tools) are not executable when installed. Is it sufficient to just “root” the device and all the blocks will be bypassed? Or would I need the custom rom after rooting to enable all features I want?

  • #15756


    I’ve heard that with the new 4.1 rom, iy’s automatically rooted.
    I have this rom downloaded from a chibese site. If you want it, I can send to you. Just give me your mail.

  • #15758


    my email is lacko(at) Thanks in advance!

  • #15788


    Mcao pls post the link on the forum here

  • #15789


    I just got the Amoi Big V N820 last week and I am really happy with the multilanguage ROM I got.
    It is not Jelly Bean yet but the functioning is quite awesome :)
    Have any of you the original default theme for Launcher 360?
    I lost it as I rooted it.

  • #16515


    Just got my N821 this week and Im loving it. Doesnt feel as cheap as the Star B92m i brought a couple of weeks back and the graphic performance seems a lot smoother (probably due to the better graphic chip)

    Easy enough to root but i cant get the play store working (prior to rooting) and im having to install apps from the PC, the links on the posts above all return a corrupt rar at some point (annoying after five hours downloading) does anyone have an alternative link for the package?  I’ve tried to get this one several times now but it just wont download the speeds are super low too (go down to about 8kb/s after a couple of minutes) then the files return as corrupt. Doh.

  • #16579


    Look at post 15667

  • #16581


    for those who want to download rom and root for N821, go to BBS Amoi and download via 360.

    By the way, how long does it take for you to receive your phone ? I live in France and my order was from november 6th ( 18 days ) ……and no news from my phone at all

  • #16615


    I had the luck of personal delivery. My father in law was in China and he bought me the phone there directly.

  • #17902


    Hi can someone download this new updated file for amoi n821 ?
