As I said before, this device cannot be bricked...The problem you have is that you haven't got the "Lenovo preloader" and "MTK 65xx USB ADB" drivers installed in your PC (instead, you have the Alcatel RNDIS interface), hence the device is not being detected while pressing the reset button :(

The only solution right now is to get hold of another device and install proper drivers or get hold of a PC with proper drivers already installed !!! After that, you can follow the above procedure to recover the device :)
[Android General] robk2544:
Great! Thank you for the reply. But I should leave in the Google DNS (8.8.8.8, 8.8.4.4) for WiFi, right?

[Android General] FoxtrotKZ:
In any case it is impossible to use the "Format".

This will result in the loss of calibration data - as imei, MAC, etc.

!!! Correct the Instruction !!!
[Android General] makbro:
Thanx for the tip :)

I have posted two separate procedures, one is for those who have complete loss (No Power ON...No Lenovo logo) that includes the "Format" option ... The other is for those whose device gets stuck at Lenovo Logo that does not have "Format" option ...

The thing is, when the device does not power-on at all, it is not recovered till you use "Format" ... Can u please advise another procedure to recover from that state ??? Thanx in advance :)

Thanks! Those tweaks seem to really help video performance. Works well.

Rob

PS- after testing for a while, I must say my problems of MX player (SW decoder) such as stuttering, choppiness and lockups during seeking a video have ended! I can even watch "HQ" youtube videos without problems. Great tweaks! Thanks again - now this cheap tablet performs so much better.

I just tried tweaking my build.prop on my -F model and now it's stuck on the lenovo splash screen...how can I restore the original build.prop? I saved it as "build.prop.old"

edit: I just re-flashed my rom and it's all good :)
[Android General] groversi:
What ROM are you using?
[Android General] AgustinArwin:
Luckily my sister will have the same device. Is it required to be rooted to install "Lenovo preloader" and "MTK 65xx USB ADB"?

Thank you,Thank you,Thank you,Thank you,Thank you makbro, it's good we have you here! I'll get back once I get hold of another device, at least a month.

[Android General] makbro:
No need to root the new device, Preloader and ADB drivers can be installed using Stock device...And you are welcome :)
[Android General] henzxy:
hi guys.. i just rooted my tab. i followed the guide posted by makbro and used foxtrot_100 rom. the problem is that the mtkdroid tools cannot detect my tab, so i cannot change my imie as i didnt backup the nvram as it was not there. by the way i check the imei of the custom rom and the one i wrote and its the same.. i even tried to call and its totally working.. does it mean its ok? or it will cause problem in future.. tnx in advance..
[Android General] makbro:
The device IMEI numbers are written on the box and on a sticker at the inside of back-cover...If you followed the procedure without "Auto Format Whole NAND Flash" option before ROM "Download" then the IMEI would not have been changed...You can verify that your's are not changed...

In case the IMEIs are changed, install "PDAnet" software on your PC, it will automatically insert all drivers necessary for MTK Droid Tools to detect your device...Then you can re-write your original IMEIs :)
[Android General] henzxy:
in short, i did good.. i mean its ok right makbro? thats a relief.. ohh yes.. without the "auto format whole nand flash", i go directly to the "download" is it bad.. or?? now i can install other roms using TWRP recovery right? im still looking for the folder data/nvram but i cannot find it so that i can backup that file.. where i can find this file?
[Android General] henzxy:
one more question... why when im using "root explorer" it says my device is not rooted.. did i miss something? thank you...
[Android General] makbro:
Yeah it's good that you followed the procedure without format...The format option is applicable to devices which do not power-on at all !!!

I think you need to run "root.bat" again to root your device...Once it's rooted, you would be able to see "\data\nvram" folder...The other ROMs that I have posted are CWM compatible, not TWRP ones...You can install CWM recovery using UPDATE 3 method of csns in this post :- http://xdaforums.com/showpost.php?p=35369121&postcount=1

Remove bloatware from rooted device

Hello everyone.

I have successfully rooted my device, which now has superuser and root Explorer installed on it. My question is - where do I go from here? All I really want to do is remove the bloatware, such as trial games, apps, etc, without modifying the device too much, and turning it into "just another Android". I don't necessarily want to install another rom, unless the rom is very much like the stock Lenovo version, but without the bloatware. I am open to suggestions as to what to do next, and which apps are safe to remove. I have looked at Titanium Backup as an option, but it won't let me uninstall apps.
[Android General] crashpsycho:
Titanium backup works great for removing bloatware I've already done that took my original from backup from 367mb to as low as 167mb. You need to have USB debugging enabled to use titanium otherwise it won't remove anything. I don't have a list of stuff I removed but if you want I can upload my ROM and you can compare

I just made a list of what I've removed here the link the understand this was done on preference and its your choice on what u choose to remove all these item can removes without getting errors

IF YOU REMOVE LAUNCHER2.APK YOU BETTER HAVE ANOTHER LAUNCHER INPLACE. LIKE HOLO,NOVA,QPEX

Lost root access (but only in Foxtrot)...

I've succesfully installed CWM following makbro's guidelines (thanks for your efforts!). Using CWM to flash a new image,

I've tested out a few: Stock (EU), LeWa and Foxtrot. Stock is obviously bloated, and LeWa by purpose has a phone-UI rather than a tablet UI. In addition, Foxtrot is the only one that supports Danish language settings and input, so my preference currently would be to use Foxtrot.

However, somehow su / superuser is NOT working in that one. I cannot gain root access however much I try (adb, busyboox, rootexplorer or even from superuser). Superuser is obviously not correctly installed. /system/bin/su points to /system/xbin/su, which looks like a 0-byte file (likely due to missing rights).

This happens on a pretty much out-of-the-box flash; full wipe of data and cache.

Any ideas on how to fix this issue? Would the "stock" root'ing procedure work if I carry that out again on the image? I did try to use adb while in recovery mode, but that didn't work, unfortunately. Any way to upgrade/re-flash superuser?

Thanks in advance for any hints!

If I use Titanium Backup to backup an app (Bubble Buster) on my phone, could I transfer it AND the data to my tablet? I'm on level 1007 on my phone, but I'd like to continue it on my tablet. Thanks for any responses! :)
[Android General] crashpsycho:
No harm in trying to find out just copy the backup from the phone and copy then into the same directory as tablet should work fine
[Android General] D1358531:
Thanks! I'll give it a try

edit: it didn't work...I put the 3 files into the Titanium Backup Folder, and when I went to restore the data, the game force closed
[Android General] makbro:
You can either run "root.bat" again OR use "MTK Droid Tools" to root the device again, no issues :)
[Android General] ursulavasey:
Wow, that is a comprehensive list you have there. I was mainly concerned with the games, and removing Norton, which take over the system and slow it down. I didn't remove the launcher at all. Titanium did the job I wanted; thank you.

One more question, if you don't mind. How do I unroot and return to stock? Just in case I have a problem with the tablet and need to return it for repair or replacement? Hopefully this will never be needed, but it will be useful information if it is ever required.
[Android General] pnomandk:
Seems to work again now -- I played a bit more around with some of the other roms and after flashing back to foxtrot, I discovered that adb got root access, and then I could fix it manually. Weird.

Now I've got another "problem"/challenge: After having flashed LeWa, rebooting has become very slow. At first I couldn't get it to boot to recovery, but after plugging in and out a few times on the computer I eventually managed to get it back to recovery and then to foxtrot. But now it seems really slow -- to the point of me not being sure if it stalls somehow during the rebooting. But it seems to cure itself after some minutes.

Any ideas on this? Could LeWa have damaged by boot.img somehow also? Or left something (HW?) in a state that needs extra time to switch off?

UPDATE: Seems like I'm only half-rooted, so I'll probably run the root.bat (in fact, I'm doing it by hand as I'm on a Linux PC here) to fix the problems.

Do I need to use the Superusers.apk and su that came with the kit, or can I use the never ones from the original source?

Also, the rebooting is really weird. If I switch off the device (e.g. adb reboot), it will disconnect and 5 seconds later reconnect to my PC -- as if it was getting up and running. But it won't switch on; the screen is completely black. If I unplug the device, I still cannot do anything with the on/off button; it remains completely "dead". But once I plug it in again, it boots up immediately.

Can it wait for something during boot, or is it trying to get into some MTK recovery mode before doing a "proper" boot? I've checked my recovery log file (somewhere in /cache) and it does in fact restore boot.img as it's supposed to.
[Android General] makbro:
LeWa ROM has the "Quickboot" option checked by default, that's why you are facing these booting issues since the device is just going to a state similar to the sleep mode...You need to un-check it from "settings"... I am quite sure these problems would be resolved once you un-check "Quickboot" from "settings--->accessibility" ...

About the SU apks, the ones included with "root.bat" script OR MTK Droid Tools (whichever you are using) are installed initially but can be updated thru autoupdate :)
[Android General] crashpsycho:
Try ROM toolbox I've noticed u can restore the app and data sperate and it's never failed when going from phone to tablet etc
[Android General] pnomandk:
Yep: LeWa may cause a subsequent ROM to fail booting

Yep, that was it! In Foxtrot, the option was unchecked, so I checked it, rebooted, and then unchecked it again -- and now it appeas all OK again :)

So it looks like LeWa not only sets an option for quickboot, but those settings remain enabled through to a later ROM, causing the later ROM to remain in semi-quick-boot mode even if not visible in the settings -- but actually fails to boot since (I guess) the correct data/settings for the later ROM has not been set up.

Thanks a lot for the quick help :)
[Android General] D1358531:
I was able to send the apk and the tar.gz file to my tablet, but where do I put them?
[Android General] crashpsycho:
If your using Rom toolbox it goes to internal SD

App_Manager/app_data < appdata

App_Manager/user_app < app apk

But make sure you do a backup with Rom toolbox on you phone don't know if it will work if you try to use titanium backup files
[Android General] D1358531:
I put the tar.gz file in the app_data folder on my SD card, but I don't have a user_app folder...should I make one?

edit: I tried using DataSync and it worked, but the game is not playable due to the resolution differences. Thanks for your help!
[Android General] makbro:
The only way to un-root the device and revert back to stock ROM is to flash a stock image using SP Flash Tool...The image for 16 GB device is (credit Foxtrot_KZ) here :- https://docs.google.com/open?id=0By3a11Z9icECSXVLWUl4djc3WTg

Stock image for 4 GB device is (credit Foxtrot_KZ & Velial39) here :- http://yadi.sk/d/7JCOYuoc2k3Cs

The procedure to flash ROM image using SP Flash Tool is as follows :-

Remember, you have to read and carefully follow all steps, one by one as I have listed below, otherwise, you may brick/ damage your device

1. Back-up the folder "\data\nvram" from your device to your PC...Note both your IMEI numbers and MAC address (for verification after installing ROM)...

2. (a) Download and extract the ROM image in one global folder in your PC

(b) SP Flash Tool v3.1216.02 here : http://xdaforums.com/atta...3&d=1360162416

(c) USB VCOM drivers here : http://xdaforums.com/atta...4&d=1360162416

(d) USB Driver installation here : http://xdaforums.com/atta...5&d=1360162416

3. If you haven't already, install the ADB drivers to your PC downloaded in step 2(c) as per "How to.doc" downloaded in step 2(d)...

4. Make sure device is not connected to PC and is powered-off...Run SP Flash Tool "Flash_Tool.exe" downloaded in step 2(b), click on "Scatter-loading" button, browse to the ROM folder (downloaded and extracted in step 2(a)) and select file "MT6575_Android_scatter_emmc.txt"...

5. Check the box "DA/ DL all with checksum" and click "Download" from main menu of Flash Tool...Now keep the "Reset" button of the device pressed while plugging in the USB cable to your PC and release the button once cable is plugged-in (reset button location is shown in a pic inside the "How to" doc you downloaded in step 2(d))...The ROM will start flashing to the device...This will take approximately 13 minutes with 7-8 different color bars completing 100% progress...Don't do anything until the big green circle appears with "Download OK" indication...

6. Power-On the device...You have installed the ROM image...Now check the device IMEI numbers and MAC Adress...If they are wrong or corrupt, delete the folder "\data\nvram" from your device and copy the folder you backed-up in step 1 to the same location in your device and restart...

Been lurking and watching the thread (now on its 175th page). Thank you guys so much for your development efforts, sorry I arrived late to the party.

Question: Rooted my Ideatab and deleted a lot of the bloatware; however, the stock apps keep coming back.

Perhaps I should dive in and put on a Custom ROM? Its a 2107A-F

By the way.... Thanks to the gent who turned root.bat into an Linux script... Worked like pure magic!

You use adb devices to ensure that the tablet is recognized by the Linux OS. Like this:

tstrike39@torden21:~$ sudo adb devices
List of devices attached
0123456789ABCDEF	device

Once that is confirmed, you must make sure root.sh is located in the directory where the rooting software is located.

Also make sure that the IdeaTab is fully rebooted before continuing.

I hope this helps.

You have two choices :-

1. You are running stock android recovery...You need to follow UPDATE 3 procedure of csns post : http://xdaforums.com/showpost.php?p=35369121&postcount=1 to first install CWM 5.5.0.4 and then you can install the .zip ROMs I've posted using "Install zip from sdcard" option in CWM 5.5.0.4...

2. The other thing you can do is to follow this procedure of mine to install either Chinese OR Foxtrot v100 ROM using SP Flash Tool : http://xdaforums.com/showpost.php?p=39219999&postcount=1280...I would recommend Foxtrot v100...

Hello pemergency,

the first, excusme for my bad english.

any links from rapidshare and dropbox doesn't work. the files probably deleted from servers.

can you insert new links?

My device is Lenovo Ideapad A2107A-H, after rooting with MtkDroidTools and instruction for activating voice call in youtube, my tablet can not boot and stay in lenovo logo boot screen. with connecting to pc, the device was not detect (in any other computer). and can not access internal memory.

when i press power button + Vol+ to enter factory recovery mode, the device shows this message "Have been in factory mode, long press the power buttun and the normal boot" and stay in this step long time and doesn't show factory reset menu.

when i press the power button for 3sec and after that push Vol up and down together android system recovery menu show to me. but with this message: "E:failed to open /sdcard/update.zip (No such file or directory) E: signatue verification failed" :(

what can i do?a

i think that with flash the device and install new ROM (like instruction that you told)
[Android General] ursulavasey:
Will a factory reset remove root? By "factory reset, I mean power/volume + into factory mode, then selecting "Clear eMMC".
[Android General] makbro:
The option you described thru factory mode will wipe-out everything from internal memory, no OS after that !!! So that is not advised !!!

A Factory Reset is done from "settings--->Backup & reset--->Factory data reset", you may try it to see if device is un-rooted using this option or not...As far as I believe, it won't...
[Android General] ursulavasey:
I don't think I will do that then. I did the standard reset as you described, but it didn't remove the root. I saw the EMMC clear mode on Youtube, in a video that Lenovo themselves posted. There is nowhere on the video that says that doing this wipes out the entire OS though. It does say that it clears the data, which is fair enough, but it doesn't mention about the OS being wiped. The video link is below:

http://www.youtube.com/watch?v=0uvU-bscH2g
[Android General] makbro:
EMMC is the format of device's internal memory...As far as I knew about Android devices, clearing emmc would format entire internal memory...However, if Lenovo has itself certified it doesn't, you may give it a try...Clearing "\data" has nothing to do with replacing "boot.img" and "recovery.img" which is required to achieve un-rooting...If the "Hard Reset" in the video carries out this replacement and the default "boot.img" and "recovery.img" aren't replaced during rooting (which I don't know about), the device would be un-rooted !!!

You need to completely un-install the Alcatel or any other wrong "Preloader" and "USB ADB" drivers installed previously...If you can, use a PC without these drivers pre-installed and try installing the drivers from the archive I've attached with this post...
