Think I've broken it

If anyone still actually uses this tablet, I need your help

I have the Vodafone smart tab ii variant of the a2107

A while back I flashed cwm recovery on to my device and it ****ed up the storage - it said I had a couple MB when I should have 4 GB. To combat this, I flashed this apk https://www.youtube.com/watch?v=V9aFPNcwajw, followed the instructions in the video and then it didn't turn on. if I hold the power button for ages it turns on but only shows a battery charging logo (not the one that used to show up) and doesn't do anything else. How can I fix this?

Unless someone builts a ROM straight from source code for our device... I'm wondering, is this device tree open-sourced anywhere? or, can we adapt another to work with this?

A2107 Bricked Blank Boot Screen no Loader

Hi I have a A2107 lenovo with two sim card model I got from ATT. I tried to flash it to the Pemergency rom but I think I have did something wrong. I I have tired it three times now but on my fourth there was a lenovo boot screen at first then I reset it and now there is not boot screen. Nothing happens, just blank when you turn it on no loader or anything. I think some one might of had this problem in a previous post but I can't seem to find it.

Problem:

1) Failed at flashing and complete wipe of Rom

2) Blank screen when turned on (no loader, or logo or anything just black...like bricked)

I remember reading late night that there is no loader installed or I must have deleted by accident so it doesn't load the loader. Could I have possibly bricked?

If anyone can help or point me to the right direction of a previous post or solution please help. I really want to get this tablet to work. I'm at the point where I don't even mind having stock Lenovo droid rom back.

Tried Holding down Power button and volume - (nothing happens), tried hitting the reset but on the back of the tablet with a pin (nothing happens), made sure fully charged (nothing happens)

Thanks
[Android General] AndroSteel:
Can you boot in the CWM recovery? If not, then you've hard bricked it. Now, don't worry! Download SP Flash Tool and flash the FOXTROT ROM using firmware update option (Instead of download mode) and make sure to have the drivers installed so SPFT can connect to your tablet. After u flash that ROM (search these forums, [MENTION=4796707]syserr[/MENTION] posted some SP flashable images) you can boot into TWRP and then flash pemergency ROM. Good luck!

Note: if u find it hard following what I said, tell me and I'll try to spare some time and help you with teamviewer.
[Android General] XlerateHighlander:
Thanks for getting back to me so promptly. Do you think you can help me out with step by step? I tried to do it on my own for the last two days trying to figure out from other post on this forum through different method. Still nothing, little frustrated but I enjoy the challenge. You are right I think I might of Hard bricked my a2107. Now that I recall I might of have format the whole device including the bootloader so that is probably why I could not boot this thing up and can not enter CMW. The whole thing just showed black and nothing appear on the screen either.

I also downloaded all the version from syserr. I also tried SP Flash tool V5.

P.S. I also have all the driver installed so my computer could read my A2107 tablet.

If you can help that would be much appreciated.
[Android General] AndroSteel:
The thread is voluminous, so don't waste time reading it all.

Hard-bricking a device, sometimes means that is unrecoverable, but this isn't our case. Even hard-bricked, our device can boot in the so-called Meta Mode (your PC can detect it - that's it; it's still alive)

That will allow us to write directly in the NAND flash (all the partitions), read them, or even changing the partition table.

Now, lets get to work:

If you have downloaded a SP flashable ROM, extract the zip files in a folder (this will be the relative directory we'll continue talking) and then run SP flash tool. Assuming that you have connected your device to PC (press the reset button under its camera to be sure), we continue:

1.Load the scatter file to make SP flash tool happy (that's your partition table and you can find it in the folder)

If you have got the 4GB version of the tablet (not the 16GB one), you will have to edit the scatter file with Notepad++, by editing the following lines ONLY, to match the below:

(note: you should add __NODL_ before them)

__NODL_FAC 0x[SIZE="1"][I]hexidecimal stuff[/I][/SIZE]
__NODL_FAT 0x[SIZE="1"][I]hexidecimal stuff[/I][/SIZE]

2.After you have loaded the scatter file, press FORMAT (don't be afraid, you cannot brick it harder than that ;) )

Wait till it finishes and:

3.Make sure everything is assigned a link:

For example: system | C:/Users/You/Desktop/Folder/system.img

4.Now check the DA/DL all with checksum checkbox and press DOWNLOAD

Have a coffee while it does his job. Reboot your phone by pressing the reset btn after the green circle appears in SP flash tool.

------------------------------------------------------------------------------------------------------------------------------------------------------

P.S. If download mode doesn't work, saying that PMT table is different bla bla bla, try the Firmware upgrade option.

If you cannot make calls or it says "Invalid IMEI" after you boot into system, restore it using MobileUncle tools (MTKDroid won't work!)

Feel free to ask for anything, I'll try my best! Good luck!

Hi guys im new here and to android(still very experienced in tech,flashing etc though,just not for android)

I have a Lenovo A2107-H 16gb model with dual sim

its really slow and lags alot and i came across this thread when i was looking for a custom rom

basically my priorities are speed and usb otg

ive already managed to root it

im scared about bricking or rendering the tab useless

i tried reading about flashing roms etc but it confused me further

can someone pls list a simple fool-proof method,download links,procedure to get a stable,fast rom with otg etc

thanks and please help me out :)
[Android General] syserr:
You should look at my ROM and FAQ threads.

OTG is a no go, unless you started from the ground up. I real custom ROM would have to be made from source with leaked source code, and could have OTG. None of the A2107A variants had OTG compiled in.

MediaTek is weird to work on. The good news is you can always recover an A2107A if you have a backup. You can ALWAYS get it in a mode where it will take a flash. Read my FAQ, make a backup first... or you will be sorry. (I bought 2 A2107A, one to fix the other)
[Android General] kkn_13:
hi thanks for your reply!! really appreciate it

I have a nandroid backup which i made with "online nandroid backup" and I have copied the NVRAM folder to my pc

I seem to have semi bricked it, I was messing around with navigation keys using "Softkeyz" and I accidently tapped "apply backup"

now my tablets wallpaper etc is gone weird and navigation keys and status bar are missing

could you link me to a "systemui.apk" to try to prevent the last resort of flashing it please

I went throught the FAQ and it made a lot of things clearer,thanks for your informative posts :)

Please help me out

also does it support xposed framework and is there a 4.0.4 rom for it?

thanks and god bless :)
[Android General] AndroSteel:
I guess there is an AT&T version for the device.

About the nandroid backups, SP Flash tool backups would be clever (that will come handy if you hard-brick it).

And lastly, simply flash the ROM again in your device; more bugs will come if you replace /system components, so start with a clean install and then keep experimenting till you achieve what you want.
[Android General] syserr:
Before you do anything, get a "real" backup of your NVRAM partition. You can do this with SPFT. Getting a copy of /data/nvram like rua1's tool isn't as good as a partition bitwise backup. As every time you wipe /data you will wipe what you restored in /data/nvram. The NVRAM partition is NOT mounted on /data/nvram, MediaTek has some algorithm to update /data/nvram filessystem from the variable contents in the NVRAM partition.

Look at the scatter file...

__NODL_NVRAM 0xa60000

{

}

__NODL_SECCFG 0xd60000

{

}

Backup with SPFT starting at 0xA60000 and go... length 3145728 (0x300000)

If you read my FAQ and ROM threads, it talks about it.
[Android General] 1498jalp:

[Android General] AndroSteel:
Your tablet is in factory mode, and that has to do with one of the partitions.

The only way past it is to flash the Foxtrot/Lewa/ whatever else SP flash tool-compatible ROM and then flash using the recovery.

You may also check the FAQ for this device, or refer to this post to get a better understanding of why the error occurs.

Hello, I have bought this tab from China, and all my apps are in Chinese, plus i think it doesnt support google play, i am having hard time at support centre in India too.

[Android General] Can0dope:
Hi, syserr. I'm back again...

So my son is here for the summer and his tablet has been acting up again... I'm the idiot who never did a proper backup, so having difficulties fixing it. I was going to use makbro's "out of the box" instructions to try and start from scratch, but the "part 2" file is no longer available. I'm at my wits end...

Basically, the problem I'm encountering is "the process com.android.*** has stopped". Sometimes its "com.android.acore", other times it's "com.android.gapps". There are also others, but these are the repeat offenders. I've tried just about everything I can think of/find on google. Also, it has stopped reading the external SD card, and I am unable to find a solution...

Any suggestions?
[Android General] AndroSteel:
I no longer own the tablet, but I'd suggest you flashing a new ROM and installing gapps. There are many alternatives: Foxtrot, pemergency, MIUI etc.
[Android General] aleksandar9999a:

Anybody know a phone with mtk6575 and Android 4.1 or 4.2?
[Android General] AndroSteel:
Are you trying to "port" a ROM? I've tried, and trust me, many people have tried, but we need MTK to open-source the device tree and compile a ROM from source code; porting is very difficult and unpredictable.
[Android General] aleksandar9999a:
​

The open source code has them on the site of Lenovo. The problem is who will help me ?? I have a brother who knows a lot about computers and maybe they can assemble something. I am from Bulgaria and people here do not know much about Android or at least my acquaintances friends. The problem is in resolution on lenovo a2107a-h,At least according to me, but If you think the problem is something else tell me! ;) :)

[Android General] AndroSteel:
Can you please provide me the links for the device tree and the kernel. If those are open sourced, we can port the latest android version (v5.1.1) and any which'll come new, but I need the links, please.

Also, to build a ROM from source you need a Linux environment and NO, you won't lose anything, but gain respect and popularity. Cheers

Momentarily, I'm at limited bandwidth, so please backup the source code somewhere safe, just in case. Meanwhile, after summer vacations I might start working for CyanogenMod 12.1 for our tablet, and hopefully will release it in September (although I'm not sure if the 'source' provided there contains what I need). Anyways, thanks!
[Android General] syserr:
I took a look at that source today, I'm pretty sure it's not complete. That is not to say it's impossible though. From what I remember, you need to have stuff in mediatek/protect/source/hardware/ril. You can probably find comparable sources out there with this directory.

I challenge you to make some progress and get me excited about helping. :) I have a build system setup on Debian 7, but have not built anything. heheh (for a year now)

Once again, I'm trying to fix my son's tablet... I was going to try one of the other roms, possibly aleksandar9999a's modded Foxtrot. However, I just realized that I must've deleted my backup of nvram...

Is this step absolutely necessary? I could see why it would be if you were planning on still having cell service on the device, but this device is solely a wifi device. It hasn't had service in at least a year now. Since that's the case, would it be safe to just not worry about that step and just install the rom of choice?

My biggest problem with this device is that it has no space for apps. So far, no matter which rom I use, he can only install 1, maybe 2 games before the device "has insufficient memory". This is very frustrating since the device itself has a built in 16gb SD, plus it has an external 16gb SD, none of which is being properly utilized by the device.

Please help me make this thing worthwhile...
[Android General] aleksandar9999a:
Nvram backup is required!!! Nvram is for sims, wifi and bluetooth. Nvram is very important!! ;)

The memory is small, yes, but i think that had method for repartition. I try to repartition, but It did not work out. The roms, that I have created, are with 2 gb internal! But if roms aren't 2 gb, install .zip from link in post for android 4.0.4 mod fine and after that install the rom.

Repartition depends on the chipset. Sorry for my bad englisch.
