If you have TWRP, first replace it with CWM 5.5.0.4 using UPDATE 3 procedure of csns' guide here : http://xdaforums.com/showpost.php?p=35369121&postcount=1...

Then use the back-up folder named "BDRS......" (the dots would be the date and time stamp of creating back-up) inside the Gscript Lite back-up folder and use "Restore" option in CWM to install your back-up...
[Android General] maiko-tz:
thanks for the info makbro!

the problem with the flash player is, that it's installed by default and whenever i try to install another version doesn't matter if newer or older it says:

Application not installed

An existing package by the same name with a conflicting signature is already installed

Is there a software to remove the flash player in debug mode without coocking a new rom?

thanks!! maiko

Definitive instructions for rooting A2107A-F

I'm new to this thread and am having trouble figuring out what is the correct way to root my tablet. I tried following the directions in an early post but the device is not found.

Well my friend if you must know, the back-up created by Gscript Lite (BDRS.... one) is not compatible with CWM 6.0.1.5 back-up format (using BLOB files) and cannot be "Restored" thru it...It is compatible with CWM 5.5.0.4 though...

Lenovo ideatab

Hi makbro. I need your help, i have Lenovo ideatab A2107A-H S_364 brought in Belgium.

I like to use phone option on my tablet and i am trying to flash one of the ROMs from this forum but no luck.

I search this forum for my problem but no answer. I use CWM 6015 and i get enter country cod, and with sp flash tool v3.1216.02 and v3.1216.01

i get this.

:confused:

i try to flash Foxtrot_100 ROM

any idea what to do.

Thanks in advance.
[Android General] sjargo:
Still not rooted.

I very much appreciate your attempts to help but I hope you can see that links to links to docs is less than definitive. I would think that rooting this device would be so basic that someone would have written it up as simple steps for dummies like me rather than embedding it in walls of text about more complex topics. If and when I get this to work I'll try writing up something straight forward and clear. I think if we just added the links to the drivers to the Word doc with the instructions it would suffice.

Your step 1 which refers to step 2(d) which links to a Word doc which tells us to install drivers for "Lenovo preloader" after connecting the USB cable after holding down Reset. I was able to accomplish that step earlier but got stumped at step 3, "USB MODEM DRIVER". When I connect while holding down VOL+, I see "A2107A-F" in device manager not "USB MODEM DRIVER".

I am also confused about which drivers get installed in step 3 since we point to the same directory with the same inf file as in step 1 for "Lenovo preloader", true? Do we just load the same driver for this new "device"?

Try installing the Chinese ROM thru SP Flash Tool v3.1216.02...Use the same procedure (http://xdaforums.com/showpost.php?p=39219999&postcount=1280), link to the ROM is given in Step 2 (a)-(ii)...

After that flash CWM 5.5.0.4 since all the ROMs here are compatible with that version, the new one uses BLOB files format !!!

---------- Post added at 03:39 PM ---------- Previous post was at 03:36 PM ----------

Installing USB VCOM (ADB) drivers is the preferred procedure...However, if you can't do it, install the software "PDAnet", it will automatically install the ADB drivers for rooting (at least) and device would be detected by MTK Droid Tools as well after that !!!

@a.ahmed...Once the device is in factory mode, you won't be able to access the internal SD for copying the nvram folder any more...If you have any kind of back-up created (thru Gscript or CWM), you can extract this folder from the back-up archive "data.ext4.tar" using 7zip like softwares !!!

---------- Post added at 03:45 PM ---------- Previous post was at 03:39 PM ----------

Using "root.bat" is also a one-click-root process...But to run this batch script, you need your PC to detect the device first...

Using the "PDAnet" software would allow you to automatically install most of the needed drivers on your PC for device detection...

I initially guided you to USB VCOM drivers procedure since it is the preferred one !!!

Hi makbro,

could i ask for a small favor, could you please tell me how to enable calling feature and fm radio without flashing. i have mine rooted today and just need this so i can use the tablet asap without messing with the device. atm im ok with the stock 4.0.3 thanks just disabled some unnecessary stock apps and change the launcher

alright scratch the post above i found time so just installed cwm

just need your input on which rom would your recommend that is stable for daily use, has calling + fm feature, battery friendly, smooth, clean and fast without bloatwares...oh and something that you might consider updating in the future :)
[Android General] makbro:
As per my testing and experience, Foxtrot v100 and LeWa ROMs are the ones you should consider...Before you do, however, like most of custom ROMs, each has two bugs !!!

In case of Foxtrot, the phone hangs and needs a hardware reset when "Auto-rotate screen" is enabled and you receive a phone call OR screen switches from Portrait to Landscape more than once within 2-3 seconds...This doesn't happen every time but frequent enough to be called a bug...Not a bummer though I think !!!

In case of LeWa, the screen resolution can't be changed and the default makes everything big and you can't perform "SIM Management" thru "Settings"...

Other ROMs have even more bugs and stability issues compared to these two...

Regarding update, sorry mate, at least I won't be updating any of the ROMs cause none of them is mine, I have just modded them to add various performance tweaks...

Hope this info helps :)
[Android General] abendroidx:

[Android General] sjargo:
Finally rooted, Thanks!

I took a chance and installed PDAnet (even though it wasn't clear which was the correct version for my tablet) and it installed the drivers I needed to root the device. I thought it might be helpful to explain that I was reluctant to follow vague instructions for rooting any device since I did that with a Kindle and bricked it.

Someone who is savvy with the A2107A would be doing everyone a big favor to put together a simple rooting procedure to replace the links to links, google searches and incomplete names of apps to run. I'm glad I'm over it but I fear there will be disasters for some of those who follow after me.

That said, I appreciate the help I got here. I was able to load Titanium Backup and uninstall a bunch of bloatware.

getting into bootloader is elusive

Around January 1, cns and a few others had trouble getting into the bootloader/fastboot. I can't see that this was ever resolved.

My situation, I have a -H with one SIM slot from ATT. It's OTAed pretty current. (hoping that isn't the cause of this) When I press PowerOn and VolDown at the same time it just boots normally. I've tried MANY timing senarios.

Ideally, I'm doing this to unlock the bootloader. As I've just got done making backups according to makbro's instructions but now I understand preboot etc are not properly backed up until the bootloader is unlocked. So I'm rooted with busybox.

(I'm trying to document all everything because as long as I have to learn it, I want to put it on the xda/a2107 wiki page too.)

Any thoughts on booting to the bootloader? Maybe an OTA killed getting into it? I'm pretty sure my rooting couldn't cause the bootloader interface to be inaccessible.
[Android General] AP756:
My two cents: Install "Absolute System" from the market, start it, open the menu and reboot recovery. The program needs root rights and it worked for me when I didn't get into recovery mode.
[Android General] syserr:
Thanks for the reply, but I don't need to go into recovery -- I need to go into the bootloader to do fastboot. I can boot into recovery using a few different methods, but not bootloader. :(

---------- Post added at 12:35 PM ---------- Previous post was at 12:17 PM ----------

I've tried:

- Holding Vol- while Powering On

- Tapping Vol- while Powering On

- Holding Vol- while plugging into USB

- running "adb reboot bootloader" which just reboots, fyi "adb reboot recovery" gets into recovery fine

- running "adb shell" then "su" then "reboot bootloader" which just reboots normally

- using Linux adb

- using XP adb with the fancy VCOM drivers that understand "MTxxxx preloader"

Nothing I've done has gotten me close to booting into the bootloader.

Questions (simple I hope)

I would be very grateful if one of the experts amongst you could comment on...

I have purchased a 16 GB A2107A-H which has internal storage curiously labelled "USB storage", and appears to be partitioned as:

3 GB "internal storage", contains stock apps and only leaves just over 500 MB to user apps

balance "USB storage", whatever I install does not seem to go there but goes to the "internal storage"

The default behaviour (in Settings) is for user apps to be installed into the "USB storage" but in practice, they go to the "internal storage". This means the 500 MB shrinks and the system slows down. There is the option - in theory - to install or move user apps to the [external] SD Card but in practice, the "internal storage" still gets eaten up and shrinks (by a much smaller amount, of course, as some of the app content does go onto the SD Card in this scenario).

Assuming I have understood things correctly, my question is...

Is there a way to repartition the internal storage say to 6 GB for "internal storage", so that the system has room to install user apps?

If so, what is the easiest way, that can be undone easily (if a need for warranty replacement arises, for example).

It would be nice if there was a simple, reversible rooting approach someone could suggest (and have ideally used and proven), and a partitioning tool that can preserve the data in the "internal storage", given the "USB storage" appears to be empty. Also, out of curiosity, what is the point of the "USB storage" given it seems not be be used even when the Settings indicate it should!

My next question concerns ROMs. There appears to be one from "pemergency" and also one from "Foxtrot", I am not clear of the origin of the first ROM, and the second appears to be a port from an A750 mobile phone. Are either of these Jelly Bean, and also which is best? Does the improvement in performance merit a replacement of the stock ROM? Are there "unforeseen consequences" of using a phone ROM in replacement to the stock ROM? And finally, how do I backup and reinstall the stock ROM should I need to. I ask because I have read that the Clockwork Mod does not seem to work with this tablet, and also because it will be the first time I will have rooted a tablet.

I hope you can help!

Regards,

Stuart

still attempting to get into bootloader/fastboot

I read that with bricked MTK devices, they can usually be fed a rom by pulling the battery, holding down VolUp, and plugging in USB power. Has anyone got the battery out of a Lenovo A2107A?

I have two questions:

1. Can I do something to "catch" the boot sequence when Windows VCOM driver sees "MTxxxx preloader" for the 3-5 seconds? Is that time window meant to be used for something?

2. Can I force a different bootloader or maybe it's a preloader onto the device with flash_image? So many tools, maybe there is something safer -- but I don't know the purpose of most of the GUI tools. A pointer to documentation on them would be great.

Behind the camera cover there is a reset button (use a pen or something to push it). This disconnects the battery as long as you push it.
[Android General] ssenemosewa:
I wouldn't recommend trying to disconnect the battery from the circuit board unless you have no other choice. The battery connector is VERY fragile! Mine crumbled on me and I had to jury rig it to stay in place. Take it from someone with experience in soldering surface mounted components: Don't mess with it.

There's a button below the rear camera which is momentarily disconnects the battery. Use that instead.

Rooting (Is not completely reversible !!!)

1. Install PDAnet on your PC, it will automatically install most of the drivers needed.

2. Extract the attached archive and run the script "root.bat", device will restart 3 times during rooting process, please wait for the device to restart completely each time and then "press any key to continue" for the script to progress.
