[Android Q&A, Help & Troubleshooting] dhoeks:
I have a chinese tablet which has no brand or model/serialnumber.

A few weeks ago the tablet stopped working (stopped during boot).

Searched for firmware and tried several ROM''s i found on the internet (I opened the tablet and found that it has an Allwinner A13 inside).

With many of these Rom's the tablet will start only the touchscreen does not work.

You can look at the pictures to see how the tablet looks.

I also found a video on youtube which shows the tabet.

I cannot place a link but search for this: Allwinner 7inch A13 Android Tablet - Overclocked - review & games PART 1

I already contacted the guy who posted this video but he doesn't have the tablet anymore.

Can someone please help me find an original firmare file for this tablet??

I found this thread today, which has details on a new T-Mobile ROM (finally!):

http://xdaforums.com/viewtopic.php?t=52119&postdays=0&postorder=asc&start=50

I have done loads of searches on this forum, but I've failed to find some information I would really like and I'm sure it must be here somewhere.

I'd be very grateful if someone could point me in the right direction, I've done loads of searches I'm not just being lazy!

1. Is there a comparison between the Qtek/Imate/T-Mobile/O2 ROMs anywhere? Is there any consensus as to which is best and/or for what reasons?

2. Is there a guide to flashing ROM anywhere? In particular I'm presuming that I will lose all my data on the device, and thus what I'm worried about is losing my text messages, as ActiveSync doesn't sync them. Is this true? If so is there any way to back up my text messages? Will I also need to reinstall all the programs I have installed?

Many many thanks,

Dave

ROM flashing guide is on wiki.xda-developers.com

Use a backup program like Spb Backup or Sprite Backup before flashing; I'm not sure if they would backup your text messages though.

Hi xda, this guide is tested only on galaxy tab p1000 2.3.3​

1. download framaroot 1.8.1 from the attachment

2. copy framaroot apk to your device

3. install framaroot

4. open framaroot

5. install superSU

6. reboot your device

7. enjoy

credits goes to: alephzain for his framaroot.apk
[Galaxy Tab General] ExcellentAndroid:
Hello badagila, I tried this and it worked but the problem is that I don't see supersu.apk installed, it's in the system app directory and it says parse error when I try to install it.
[T-Mobile LG G2] dr87:
LG 4.4.2 Stock Rom - Massively debloated, only has a few apps left. All LG features should work. Requires custom recovery. Do not flash AOSP or 4.2.2 kernels.

This includes my new updater script for kitkat so it actually has a /system folder instead of the system.img.

You can find the standalone updater script here. I believe it is the first created, every KK rom I've seen is not editable using a system.img. It took a few hours to create.

The kernel is stock but I made some small adjustments and toolchain fixes.

I have a custom kernel for this up in this forum.

Instructions.

Full wipe besides for internal storage

Flash Kitkat modem here (If you aren't already using it)

Flash Rom here (mirror soon, but not yet since I need to reupload)

Flash SuperSu here

If you get a "symlinks failed" (happens right away if system doesn't mount properly) reboot back into recovery re-wipe and flash again.​

It will download if you go to the torrent file using a file explorer like estrongs. I don't know why it doesn't work the way it used to by just opening up after downloading the torrent file but at least your not totally screwed.

[T-Mobile LG G2] Nitefire77:
To flash this version do you still need the a bootloader or can the g be used now?
[T-Mobile LG G2] dr87:
you can try it on G just backup first
[T-Mobile LG G2] KennyJive:
twrp 6.3 failed had to upgrade to 2.7 for it to flash.

i've tried every single Kitkat rom I have get my hands on, followed the instructions to the letter and if I turn this screen off and turn it back on, its just lines. White lines or colored lines. Every single f*cking kitkat stock rom. I don't get it. i'm ready to throw the thing into the river.

I know its not your rom, and it works flawlessly as long as I don't turn off the screen.
[T-Mobile LG G2] dr87:
This is probably one of the most confusing issues to me since everyone here has the same device, downgrading to the same exact partitions yet some people have these line issues which makes no sense to me at all. I've been trying to figure it out but its a pretty confusing issue, its not like we have different variants. We can maybe try upgrading tz and rpm partitions since they will work with this bootloader

The only thing complete stock has that this don't is the new partitions and I'm really not sure why it's causing issues for some people

@dr87 Have you tried downloading again since your last try resulted in a 20a kdz download? I have a 20e kdz for my D801, but I am not sure what to do with it, and how it might be affected by my/your existing installed kernel and bootloader choice...

Using the #3845#*801#, my Kernel version is "3.4.0-perf-ge9c5cc3-dirty dr87@dr87-linux", so you be the man. :D

Phone downloaded a system update that clocks in at 306 MB. Any word on what it is? 4.4.3? 4.4.4?
[T-Mobile LG G2] brettsmods:
Same. Is it safe to install on this Rom? And Will it update properly and keep all of my data?

Or should I not install because it could brick the device?
[T-Mobile LG G2] cvsolidx17:
According to others who have updated, root is lost but can easily be gained again with towelroot
[T-Mobile LG G2] MarkAtHome:
It is an updated v4.4.2 (D80120e).
[T-Mobile LG G2] jaed.43725:
Updating from dr87 ROM bricked my phone. I had to use the LG tool to bring it back. And nobody has an up to date S/W file for it. So I had to go through 3 updates. Then towelroot. And DO NOT use that easy method of getting TWRP. You need to flash it from the side and then use X-Posed to get 4-way boot menu back. The easy method causes lines on the screen.
[T-Mobile LG G2] dr87:
I won't be updating this rom with the new ota, sorry :(

It was a one time upload since at the time we didn't have any 4.4.2 roms up for us, now there are a bunch of choices with cloudy's roms and I don't really like working with stock roms :good:
[T-Mobile LG G2] MarkAtHome:
I understand that. If memory serves me, and it has been frequently failing recently, weren't you using the old bootloader with its partition scheme for your v4.4.2? If I am partly right... how would we be affected by flashing the above-mentioned KDZ file, which I guess would have a different/more_recent bootloader?
[T-Mobile LG G2] dr87:
New bootloader is still locked and probably will always be, flashing new kdz = upgrading the bootloader = no more custom roms / kernels until downgraded again
[T-Mobile LG G2] MarkAtHome:
So:

Is there an advantage to having an upgraded bootloader?

As long as I don't flash the KDZ (or do an OTA), thus

retaining

your older bootloader, I can flash any third party ROM/Kernel

over

yours, as they will work with the older bootloader and not require the updated one, yes?
[T-Mobile LG G2] dr87:
1. No

2. Yes

The new bootloader is bad news, stay away from it

Its not exploitable and blocks custom recovery / roms / kernels

:good:
[T-Mobile LG G2] MarkAtHome:
Excellent. Thanks for your quick responses. I appreciated them.
[T-Mobile LG G2] dr87:
No problem, if you really want to try some very stable stock based roms, try cloudyflex or cloudystock from the android development forums. They are pretty amazing roms, cloudyfa is a really good dev and focuses on stock roms. Cloudyflex is what I have been running since its release.

[T-Mobile LG G2] Renarudo:
Thanks for the replies, all. I'll ignore it then since I plan on using this debloated 4.4.2 ROM until I move to the LGG3 later this month, as battery life with custom ROMs wasn't anywhere near as stellar (i didn't feel like messing with kernels).
[T-Mobile LG G2] MarkAtHome:
I have kept an eye on his work but have not yet been sold. He seems very responsive, though. Any reason you didn't mention his G3 port?
[T-Mobile LG G2] dr87:
It's still new, has a few issues which he has been working out quick. I liked the dark theme of flex and it has been 100% stable for me.
[T-Mobile LG G2] MarkAtHome:
So I'm safe in flashing the Flex ROM over yours. Can I retain my data, or will I have to restore my data via a Nandroid data restore after flashing it?
[T-Mobile LG G2] dr87:
You would probably have to wipe data, and not restore it (unless you restore individual app data)

Completely different rom bases, data must be rebuilt
[T-Mobile LG G2] MarkAtHome:
Presuming I stick with Dalvik, what if I were to restore data, then immediately delete dalvik. Would that not rebuild the app data?
[T-Mobile LG G2] dr87:
the data partition is different than dalvik, if you restored data on a completely different rom more than likely you would get a lot of FC's and the rom wouldn't work correctly
[T-Mobile LG G2] brettsmods:
I have this installed, as well as root and TWRP, and I'd like to do the d80120e update. Is there any way I can do that without losing my data?

[T-Mobile LG G2] ron_e:
Sorry to hear you won't be updating this. My challenge with any of the ones listed above is from what I have found, none of them support wifi calling. That is a feature I count and and I have not found a current ROM that has it except for fully stock.
[T-Mobile LG G2] pottyvick:

[T-Mobile LG G2] MarkAtHome:
[MENTION=5232783]dr87[/MENTION] -- So, I took your vote of confidence, and bit the bullet. I did not go for Flex, but did go for his G3 port. No problems so far.

Few questions.. does this have the wifi tether app? Hoping not and I can use tetherfy without it hitting my hotspot usage. Also any proximity sensor issues.. The aosp rom I'm using now is really annoying with the screen coming on while I'm in a call.. hitting buttons with my fat chin.

[T-Mobile LG G2] MarkAtHome:
Well, the G3 port was interesting, but I have returned to rooted-stock. I actually like LG's ROM as is.

I installed the stock KDZ of KOT49I.D80120e (data was backed up, but did not survive flash), used Towelroot to gain root, ran Autorec (D801 version) which installed TWRP 2.7.0.0, then restored data with recovery and Titanium Backup utilities.

Voila.
[T-Mobile LG G2] bigcletus:
Did you ever flash back to this? I need wifi calling for an upcoming trip and would like to flash back to a stock 4.4 Rom but I don't want to have to jump through hoops in getting it to work. Seems like just wipe data/factory reset in TWRP then flash this would work right?

[T-Mobile LG G2] mc00:
hello, everyone...

I really like the stock rom came with the phone 4.4.2 I got awesome battery but I had to switch to different rom CM11 nightly 10/25 because I'm on metropcs and I use tethering heavily , on the stock I couldn't get tethering working right I got constant upsell no matter what agent user I use, and I'll use my person vpn and would be slow as hell. but as soon I switch to CM rom I don't have this problem and i can tether fine with agent-user or vpn.

So my question is does your debloated stock rom has all upsell crap removed and how the tethering?

[T-Mobile LG G2] MicroMod777:
If u get update, do not update.

Pull down the notification bar and tap and hold on the notification. App info will pop up and tap it and scroll all the way to the bottom and uncheck show notification.

Then use root explorer and delete /system/app/lgfota.apk and lgfota.odex.

If u took ota your stuck in twrp.

Try this for fix.

You go TWRP -> Terminal command -> select and type.....

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

then hit enter

type

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

As far as I know D80110c bootloader is still required... but no one has posted of this one working on D80110g that I know of, but with the modified kernel of dr87's it might work. You do need to flash the 4.4.2 baseband though. Feel free to give it a shot though you wont lose your recovery. Just make sure you backup your 4.2.2 install, and have the 4.2.2 baseband to flash back to if you need to go back. (Hopefully you wont need to)
