You should push back these apps:

- com.android

- com.lenovo.reboottest

- com.lenovo.settingwizard

- com.mediatek.factorymode

- com.mediatek.mdlogger

- com.mediatek.mobilelog

- com.mediatek.vlw

Now you'll have to push these apps back to /system partition.

Assuming # has appeared and its ready to accept commands, write:

mount -o rw,remount /system

-This will mount /system partition as read-write.

Now, you have to get all the .apk files of apps mentioned above and put (copy) them in a folder in desktop, I'm naming it 'apk'. Let's push this folder to your /sdcard by opening a new cmd.exe and writing:

adb push C:/Users/You/Desktop/apk /sdcard (note that there is a space between apk and /sdcard).

Now head back to the previous cmd where we had the # sign and write:

# cd /sdcard/apk

# cp appname.apk /system/app

# chmod 644 /system/app/appname.apk

I know its a lot of commands to write, but you must substitute the 'appname' with the actual file name of the .apk (like com.mediatek.vlw.apk)

Now, exit the shell:

# exit

$ exit

And then type:

adb reboot

Your tablet should reboot and those apk's will be installed as system apps once again.

If you still have issues, boot into recovery and do a factory reset and a cache wipe.

I hope this will solve it, so you won't have to mess with SPFT. Cheers

When i open the new cmd in order to push apk1(that's how i name it) folder in sdcard i get a no permission error.

As a consequence the #cmd can't find a folder apk1 in my sdcard.

I am posting a screenshot with the two cmd's and the apk1 folder with the apk files.
[Android General] AndroSteel:
For me it works flawlessy (but I'm running a lollipop build, so many things can change) but I think your /sdcard isn't mounted. Anyways try to substitute sdcard with sdcard0

If that fails, close the #cmd and write this to the other:

adb root

Then:

adb remount

And try again.

You can also push files straight from the PC:

adb push apk /system/apk works as well (this is gonna automate the copying process), but you need to mount the system with adb remount command mentioned above.
[Android General] pivotier:
I finally made it to push apk1 to sdcard,(i get : 7 files pushed, 0 files skipped)

but when i try the : # cd /sdcard/apk1,

i get : No such file or directory

p.s. : as you made already enough and i feel that i am not going to make it, maybe we shall proceed to the format option ?

What do i have to loose ?

It' s almost a week with an 'out of order' tablet,

i don't have data to care about on it,

and i think that i can live without an IMEI.
[Android General] AndroSteel:
We don't want to make things worse. Without an IMEI, your tablet loses its mobile data connectivity.

Try this:

# cd /sdcard

I think this is gonna work. And looking at my signature you'd understand I haven't done anything until your issue is solved :)

Edit: I've spent three weeks trying to recover this tablet from a hard brick, trying everything. I didn't even get proper sleep, like 2 hours in 24. But then I managed to recover it (and after that, resetting IMEI), even getting calling capabilities and carrier-unlocked. You can invest some time now and it will pay off in the future.
[Android General] pivotier:
cd /sdcard works,

but still can't find apk1.

I also copied via pc the files of the apk1 folder to the sd card and i can see them when i browse through pc or through the tablet,

but when i try the cp appname.apk /system/app command,

i get : sh: cp: not found
[Android General] AndroSteel:
It seems like when you push a folder through adb, only the files it contains are pushed, not the actual folder itself, so 'apk1' doesn't exist.

Let's try to push the files straight to /system

In the normal cmd:

adb root

adb remount

adb push apk1 /system/app

And then in the #cmd:

# cd /system/app

# chmod 664 appname.apk
[Android General] pivotier:
No. I copy pasted the files of apk1 folder via windows exlorer, that's why i can see them in sd card.

As for pushing the files straight to the system,

i already tried, but when i write adb root,

i get : adb cannot run as root in production builds.

I googled it and i found this solution : http://xdaforums.com/showthread.php?t=1687590

which didn't worked also
[Android General] AndroSteel:
Did you try mounting the system as RW with the first method (on #cmd) and then pushing the files by adb push?
[Android General] pivotier:
Yes i did it this way but i still get the adb cannot run as root in production builds error.

Another thing i tried to install the apps by clicking the .apk files directly from the tablet's built-in file manager.

The installation starts and concludes for :

- com.android

- com.lenovo.reboottest

- com.lenovo.settingwizard

- com.mediatek.mobilelog

but i don't think that they are installed, cause if i repeat the procedure the installation starts and concludes as it never happened before.

When i do the same for :

- com.mediatek.factorymode

- com.mediatek.mdlogger

- com.mediatek.vlw

the installation doesn't start and i get a : the application is not installed message.

Nothing change for the functionality of the tablet in all cases though.
[Android General] AndroSteel:
^ This way, the Android shell is running as root, not the adb itself, so root daemon will not filter the commands. This is how you mount the system with #cmd.

You cannot install them from the file manager, because they get installed as user apps.

You need to do adb push (not in the #cmd)

adb push C:/Users/You/Desktop/apk1 /system/app

This must work, because you've already mounted /system as RW.

And then head back to #cmd, because system apps need certain permissions and write:

# chmod 644 /system/app/appname.apk

Then reboot.

Edit: I will also try to do that in my phone.
[Android General] pivotier:
It doesn't work.

Look the screenshot with the two cmd's and tell if i am doing something wrong
[Android General] AndroSteel:
This is very weird (I tried the same commands and it worked for me)

Could you install Root Explorer on your tablet and mount system as RW (either with #cmd, or from RE itself) and copy those apks to /system/app and then run the chmod command from #cmd
[Android General] pivotier:
I had Root Explorer already installed, so i mounted as RW from RE,

but it gave me another time permission denied.

In order to give you more clues, i want to remember you that the push adb......../sdcard almost worked yesterday.

And i say almost cause as you can see in my yesterday post :

I don't also know if it has something to do, but this tablet was bought by my mother from a newspaper as part of a subscription at the time.

Maybe they put some particular software, lock or whatever, that needs special treatment ?
[Android General] AndroSteel:
Mediatek SoC's are very messy and what works for one, doesn't work for the other.

Please take a backup with SPFT (search xda: 'syserr backup SPFT')

Make sure you have the ROM_0 blob (its usually named like that) and then load the scatter file from a SPFT-flashable ROM (already told you where to get these)

Go and do a Format (with the newer version of SPFT)

You need to press the reset button when your tablet is connected (same as with Download), so the PC detects your tablet.

After the Format, the PMT table will be formatted according the data on your scatter file.

Now press Download and wait.

After it finishes completely, unplug the cable, press reset button, then power on the tablet (first boot will take a while)

Caution: DO a backup whatsoever, even though you may not use your data, the backup will contain other important things, which if somehow are overwritten (SPFT messes up things very OFTEN) cannot be restored.
[Android General] pivotier:
I loaded the scatter file from syser's downloaded ROM.

Format process completed without errors.

Download process completed without errors.

Tablet can' boot.

Lenovo logo appears, then disappears and the tablet stucks at this point.

edit : i now noticed that when i formated the Format whole flash except bootloader option was ticked.(by default)

Maybe i should tick the Format whole flash option and repeat the process ?
[Android General] iqbalahmed:
I have a lenovo ideapad A2107 H. google play store and google play service isn't running on this tab. what should I do
[Android General] AndroSteel:
Sorry for responding this late, been very busy in real life. Now, right on the topic:

If you have backed it up, then yes.

As far as I remember a backup can solve anything going wrong.

Not formatting the bootloader, SPFT overwrites the stock bootloader bytes with the custom one you are flashing, thus making the image invalid.

You need to format it, yes.

---------- Post added at 01:06 ---------- Previous post was at 01:03 ----------

Do you own the European version?

Has the service worked before?

Are the google apps even installed?

Please provide more information.
[Android General] pivotier:
I formated the the whole flash, download and i had to make also a hard reset in order to make it boot.

Now everything seems to work as it should.

Thank you very much for all your help AndroSteel.
[Android General] AndroSteel:
I'm very happy to hear that. And, no problem!
[Android General] iqbalahmed:

[Android General] AndroSteel:
You can root your tablet and install gapps easily by pushing them to /system partition. Please make sure to check syserr's FAQ (search xda) and also google how to root this (and you may want to flash a custom recovery: CWM or TWRP) and flash gapps as a zip file (note: gapps must be ICS gapps)

I've managed to brick my a2107a 3g tablet

Hi

I installed an ap to increase the internal memory by taking from internal sd

with Mt657xRepartition_EN.apk but something went wrong

and now it boots up to a black screen and that's it.

I have a backup with CWM but upon restore nothing changes, still black screen.

CWM is ok, it's charging ok showing a big charging icon but nothing else works.

I wanted to do a couple of things and i messed it all up: rooting, CWM,

increasing internal memory to install more than a browser on it,

fixing the phone part since it does not make calls by default. What can i do?

(later edit) fixed - i managed to install MIUI_v4.0.4 _IdeaTab_2.9.15
[Android General] AndroSteel:
Haha, glad to hear you fixed it, I have the same exact version and the tablet is carrier-unlocked and calling-capable (idk, it may be because I've messed with it too heavily) however its eating dust now, until someone builds a custom ROM for it (if ever).

Hi Guys !

How are you ? I have Lenovo Ideatab A2107A-H, Android 4.0.3. I was trying to upgrade Android 4.0.3 (ICS) to Android 6.0.1 (Marshmallow). I was trying to download TWRP using Flashify but there was no relevant version for my tablet. So, I used Recovery.img file which I have downloaded from somewhere on internet. But when I flashed Recovery.img file using Flashify my lablet rebooted but the the screen stuck on Lenovo screen at the start. I reset my tablet many times but in vain. I also tried power button + volume up button at the same time to go to factory reset but it did not work as well. After that I fully charged my tablet and press power button to start again it stuck on lenovo screen. Would you like to help me out. I will be very thankful to you !

[Android General] wmaker:
Many thanks to pemergency for the mod. Installed without any problems. Calling feature works without any issues.

However I have two quick questions:

1. Is it possible to revert to the stock battery icon near the clock instead of the percentage battery display? (If the battery is let's say at 80% the numbers are always counting down from 100% every second or so, until it reaches the current battery level).

2. Have anyone managed to install flash player successfully? When I try to run the flashplayer apk, I get the following message: "An existing package by the same name with a conflicting signature is already installed" - however flash doesn't works.

Thank you for your time!
[Android General] pemergency:
1. It is possible to change the battery icon but for this you need to decompile framework-res, change the graphic files and compile back. This is not for someone who dont know to much about programing. Battery is counting only if its charging.

lol. it reminds me the time i was one of the early adopters to the galaxy exhibit ii 4g. it had no roms and no development. a year later, it has the latest jelly bean and CWM and overclock kernels and now has a thriving dev community on xda.

I'm contacting some xda developer friends to convince them to buy the lenovo a2107 so they can start developing for it. lol. my guess is within 6 months we will have some custom roms and kernels. the MTK6575 A9 processor can be overclocked to 3 ghz i believe. imagine that! this tablet has so much potential for the $149 price tag.
[Android General] manwithmanypiercings:

yea i hear you. If this tablet gets jelly bean 4.1 stock rom and an overclock kernel say to 1.5mhz or something, i'd be thrilled! 4.1 is much better than 4.0. maybe lenovo will send out an update in a few months.

CWM installation

Dear all

I found that it's much easier to install CWM 6015 according to http://xdaforums.com/showthread.php?p=35406316 ;)

It was just a snap to do it with MobileUncle and without using the reset button.

The only trouble I had :o was just with generating the new recovery.img because I first had to add the correct write and change permissions for

everyone

to my working directory on Windows7 for making the tools operating correctly.

The old firmware is still working. The benefit is: you can make here a complete backup of your old stock ROM out of the CWM environment with all your customized data, so if anything goes wrong you could restore it.

(If somebody knows how to do it: this could be part of a restoration algorithm for getting the old user data out of the images, like email accounts, messages, game scores, registrations and more ... if not backed up :( - like it should be ...)

A Shutdown of the system does also work, but anyway ...

After upgrading I realized that the IMEIs on my pad kept there original data so I was not required to correct it.

So it's wise to check that first ...

Finally it was a very good experience in upgrading from an ordinary tablet to a SmartPhoneTablet. :cool:

My best Thanks !!!
