Amoi Big V N820 Update To Android Jelly Bean 4.1!

Written by

NOTE: A reader wrote in with news that this JB build may not be completely stable. I followed up on the message and found that this is unfortunately indeed the case. There is some buggy behavior happening with some users who are installing this build. Keep in mind this is the first public release, so this isn’t exactly unexpected. If you still wish to give it a go, please make sure to make a NAND ROM backup with Titanium backup before you update in case you need/want to switch back. This is ROM is released by Amoi. However, REMEMBER that you update at your own risk.

In my previous post I gave news of the Amoi Big V N821 release with IPS and Android Jelly Bean 4.1. While current Amoi Big V N820 users obviously can’t upgrade their LCD to IPS, they can download and install the Jelly Bean ROM.

Remember you will lose everything when you update, so make sure to backup your contacts and any apps you want to save the data from. A couple of programs you can do this with are Go Backup Pro, Backup Wonder Machine or Titanium Backup.

It appears that some Big V N821 weren’t released with Jelly Bean. If that’s the case , you can skip download #1 and commence with #2 to get to Jelly Bean goodness.

For Big V N820, you must first install the latest v6.0 Big V build before upgrading to Android Jelly Bean 4.1

I did successful update (and didn’t lose any data from Native memory card btw.) for my Amoi N820 to Jelly bean 4.1.1 but this firmware is not rooted, do you know how to root this 4.1.1. firmware?

    oh and btw. except not rooted FW it doesn’t launch Google Play Store, it is launched but after half second it’s switched off, I checked BBS Amoi forum and there is already different Jelly bean firmware which should be rooted with Google play store (GMS), but it’s merging partitions so I am little bit afraid to flash it, I would prefer somehow find how to root this N820_JB_V2.0_USER_2012-10-31.zip firmware and also how to launch succesfuly play store or at least how to launch play store, I can survive without root :-)
    
    didn’t noticed any instability so far since yesterday morning, but been quite busy other stuff than play with phone, just installed and checked few games and tested wifi and checked all settings

      Excellent news. Thanks for the report back. Yes, I saw that new ROM as well. That’s actually what I had in mind for you. I’m working on a root post now. Not sure if it will help with Amoi or not, but it should work for most phones.

  Thanks for the report Tester, please check out a couple of my recent posts regarding possibly rooting Amoi N821 so you can apply a Google Play fix. If you can’t find the ADB drivers, then try the PDAnet generic ADB drivers. Then regarding root, try this method. Please report back with your success or lack of. Thanks much.

  excellent. thanks for the update regarding root success with the Amoi n821. next step is to sideload (allow installs from unknown sources in “Settings -> Applications”, then install the downloaded Google Play APK through the file manager on your Amoi). Here’s one of, if not the most recent versions of Google Play Store –> click to download Google Play Store. Please report back with your success or lack of. Cheers.

    Hello Markoff… I recommend you use the Amoi N821 / N820 pre-rooted Jelly Bean ROM in the more recent post. Please let us know how it works out.

This didn’t work. Play Store opens, then it’s closed.
