[Q] How do i update my 4.1.1 tablet to 4.2? - Android Q&A, Help & Troubleshooting

This is my first android device. I used the search option but didn't find anything useful since i have a chinese tablet. I have a "Chuwi V10" with android 4.1.1. I want to update it to 4.2 manually. How do i go about it? Thanks in advance!

You need to wait for manufacturer's updates (it's a chinese device... so don't expect too much).

No, you need a ROM specifically developed for your device.

I want to know too. I have a Chinese dual SIM which I would like to update. Is there a standard or generic Android OS updater?

Of course not. There are many different devices, so is very difficult develop a tool like that.
To both: The updates are device-dependant, so you need to wait for updates from your manufacturer device. However, you can try a ROM developed for the chipset of your device (you can get the model using CPU Identifier). Of course, this way gives no guaranties of good functionality.

[Q] Problems updating Hyundai T7s tablet to jelly bean 4.2 (official rom)

Hi all,
I'm encountering some problems when i'm trying to update my Hyundai T7S tablet to the official jelly bean 4.2 ROM.
I've the update from the Hyundai website (hyundai-digital .cn). This download comes in a .rar file. I knew it would be impossible, but tried anyway to flash this file from the SD-card. But to make it work this way, the update should be a .zip-file.
In the .rar file are 15 files, some of them are .bin and .img files. And I've not the knowledge what I can do with these files. Unfortunately the support guide of Hyundai can not be opened and two hours googling didn't help me out. So here's my question:
Is it possible to convert the .rar file into a .zip file and flesh this file? Or can I flash the rar-file in some way?
Thanks!
ps. i had the full links copied in my message, but since this is my first post, i cannot post links. Sorry for that!

Extract all files in zip to SD card (ext.). Power OFF. Press Volume - and Power and update will start. Looks like you use Volume + not - witch takes you to recovery mode. When done tablet will turn OFF. Power ON and you should have new firmware.
You are talking about "HYUNDAI T7S-20130318" ?....if yes it is not 4.2 is still 4.0.4; If you found a most recent one (4.2), can you email me with download link please ?....I can't find 4.2 for T7(S). Thank you !
I think 4.2 is not yet aivailable at all.

exactly. even though some sites advertise it as a 4.2 device, the latest available stable fw is still the 4.0.4 from the 18th of March.
I just tried exynos abuse 1.4 about 2 hours ago on my t7s and it worked like a charm.

Another T7S user here, waiting for 4.2, too. Is there something wrong with the website? When I visit http://www.hyundai-digital.cn/ it tells me:

from what i've read (some weeks ago): the main hyundai company has told that branch producing the tablets not to manufacture devices to be exported from china, so they're cutting the rest of the world off their official site --> you'll be able to reach the webpage via a chinese proxy (as if you're browsing from china).
about the update for which we're all waiting for: last time it was told to be released in 2013 june, so i still haven't given up yet. anyway: just search for "slatedroid" on the internet if you'd like to get updates about the tablet in english

Another possibility could be porting CyanogenMod OR buying a tablet to a developer. We already have CM for the same SoC, so I think about xplodwild or codeworkx, the two main i9300 maintainers

That would be great!
This tablet will literally fly with CM.
How can I ask to a developer to port to this device? Is it there a specific forum? Or just pm them?

Well that'd then be the reason why the 4.2 ROM for the rest of the world is now available to download through MediaFire rather than an official Hyundai page.
For those who haven't found it yet, this post on the GeekBuying blog details the download and installation of the 4.2.2 upgrade.
I'm in the process of downloading the 222Mb archive now; going rather slow which is nothing new for MediaFire.

Sorry for my bad question and thank you for your reply.
My vendor doesn't provide the update for my device.

Any specific system requirements for upgrade version?

yea. That is what I am looking for but sadly I am not the programmer.

Lenovo Yoga Android Tablet 10" & 8" latest root/recovery/ROM info?

The Lenovo Yoga Android Tablets 10"(b8000) and 8"(b6000) (aka Yoga Blade) seem to be the red headed step child around here.
I feel like I dropped the ball back in December when I started to try to get CyanogenMod on the b8000 and never finished.
Working with MTK processor was intimidating and demoralizing.
Things seem to have changed a tiny bit since I dropped out. There is a new Firmware update (http://lenovo-forums.ru/topic/5045-rom-yoga-10-b8000-a422-000-072-140122-ww-wifi-ota/) and a TWRP recovery is available (http://lenovo-forums.ru/topic/4517-...oga-tablet-b6000-wi-fi-и-3g-b8000-wi-fi-и-3g/).
There is no update to the kernel source (http://mobilesupport.lenovo.com/en-us/products/yoga_tablet_10?tabname=downloads).
Anyone gotten a custom ROM, especially CM, on the Yoga Blade?
I thought it would be easier to get CM10.1 (Android 4.2.2) up and running, since that is the official stock version.
Of course I'd be ecstatic to get CM11 running.
I'd like to make another attempt at this, but I do not think that I can do it alone.

Is it worth effort?
As this is an MT8389 Soc running @1.2Ghz is it really orth theeffort to do all this CWM/TWRP recoverystuff? Since most of LENOVO phones lower mid range like my A880 is running MT6582M (quadcore), but I am a LENOVO Pc user too. It will be interesting to see development of the YOGA 10 using MT8389 maybe upgrade to CM11 but how many device sout there is currently using MT8389 anymore since MT 6589/6593 is introduced.
there is no motivataion except for die hard YOGA Pad users.
Anyone tried this or has more info?

I am surprise to check that there is an update to Kitkat OS for my MTK CPU tablet last night, download and upgraded to 4.4.2 with half an hours.
I used CPU Z to confirm it is really Android Kitkat OS 4.4.2, sad thing is that some of my app is not working with 4.4.2 OS.
My root is gone and unable to use Framaroot to root my tablet now, still trying other tools to root.
So did anybody managed to root the tablet again after upgrading to 4.4.2?
I've got the update notification but still waiting to upgrade, wanna be sure to have root permissions again first!

Framaroot latest version 1.9.3 still fail to root for OS 4.4.2 but finally manage to did it via Chinese one click root application Vroot
http://www.mgyun.com/en/getvroot
This root tool is very easy to use.
It is different from all other root method which will install super user application on our android device but this root tool will install a Vroot application which include built in super user to manage root access.
You can uninstall your old super user app and it still working fine.

Here's more info about the vroot method incl step-by-step guide:
http://www.patchworkoftips.com/root-lenovo-yoga-8-android-kitkat/3727/
Personally I'm with the guy who wrote this (i.e. Chukwudi Emmanuel Udegbunam) and leave my fingers off Chinese software that gets (a) installed on my PC and (b) replaces the regular SU binaries with their own version (which apparently cannot be replaced)
Good thing is there DOES seem to exist a root exploit. Hopefully someone on XDA will be able to port it and enable regular SU.

I allowed the update hopeing Levono would have left in the multi user feature.. they deleted it.
I have been experiancing various bugs,, DO NOT ALLOW THE UPDATE!
I wish I could go back. no more root access so the multi user app will not work
biggest issue Pandora, Amazon Music; while streaming the feed will stop for a moment then the music speeds up then slows back down, this stopping happens constently I hate it.
NEED A CUSTOM ROM!!!

Upgraded & rooted
Hi,
upgraded my Yoga a few days ago and rooted with Vroot from a virtual machine (disconnected from the net and ready to restore a snapshot ). After that installed SuperSU again, removed the Chinese installations from Vroot and being happy now with a rooted KK-Yoga. :victory:
MultiUser can (according to a little search) be activated after rooting.
Found no bugs in the new rom but I am not using Pandora or Amazon Music.

I just setup the flash tool and flashed the latest 4.4.2 rom from the russian website over my rooted 4.2.2 so far its working fine.
Had one issue where it would turn the screen off.. So it would time out and the screen would go off and the power button would wake it.. But not let it sleep. And holding it wouldn't bring up the power menu. Or even force restart.. But I used the schedule power off feature to get the tablet to shut off.. After I turned it back on it works fine.
Also one note. If you are on 4.2.2 and you rooted it and you deleted system apps. And you can't get the ota update to finish in recovery.. You don't need to flash back to stock 4.2.2 you can instead flash 4.4.2 ROM from the Russian website right over top.. Only problem is it goes to setup in Chinese if you can get through it you can change the language back to english

There is many Chinese root tool which is able to root our Yoga tablet with KitKat.
My advise is to unroot your tablet before apply the KitKat 4.4.2 update from Lenovo.
Two of us report same issue of unable to root with the latest update of KitKat 4.4.2 released last week by Lenovo to fixed the bug issue of the first release of KitKat.
We had to flash back the original KitKat 4.4.2 ROM to root again.
http://forum.xda-developers.com/showthread.php?t=2791072&page=3
You can even try the Kinguser APK method to root your Yoga Kitkat 4.4.2

I'm just fed up with the new android version with their unusable tablet interfaces, so i wanted an old ROM that still has a Tablet ui. Unforunately most of the old download links are dead but i'm sure somebody here can help me.
If theres no other way i'll also take a sony ROM.
Thanks in advance for any responses...

You didn't specify device model, without it will be difficult to help you.
Also to restore tablet ui you can use mod for 4.2.2 firmware or Xposed module for 4.4.4

I logged in after about 3 years and realised, that I never responded. Thank you very much. I'm now using LineageOS and the Tablet is still running. And I guess Android Tablets are dead but I'm planning to use this one as long as possible.
