Yes I've got H, 4 GB. After reformatting should be about 2,35 GB internal memory.

Now it's 1 GB internal (for application) and about 1,35 GB internal sd (for files).

Rest of flash is for system.

As I read needs to compare MBR and EBR partitions...

A2107A-H has indeed 4 GB of eMMC. Part of it is used by system and cache partitions, while the rest of the size is divided into internal storage (approximately 1GB and an internal sdcard partition (approximately 1.35 GB. If you find that an internal sdcard partition is useless (and have a big external sdcard), you can extend userdata partition (internal sdcard partition completely disabled)

Its been a while since i read this thread, it was about 50 pages long at that time, can anyone give me an update on this device, what roms are now available?
[Android General] syserr:
For all those reasons I created the FAQ linked to in my sig.

For the -F... I'm finish up work on a scrubbed and rooted version of the *last* stock ROM. I'm going to then release a version that is a bit more pimped. After that I plan on seeing on the -H what the diff is in last Chinese kernels an last US kernels.

My -H is the 16GB single sim version sold by AT&T. I'll cripple mine and see if I can get the behavior you desire.

I need the device driver.

It says"Device Not Found" can someone please link the Lenovo a2107 Software Thanks in advance! The root file works fine. but I need the device driver.
[Android General] ursulavasey:
The device doesn't have a driver to download as such, but to get the drivers working, you need a program called pda.net, which can be found at the link below. Download it, install it, following the prompts to disconnect and connect the device, then the drivers will install, and the device will be recognised by Windows or Mac, depending on your operating system.

The rom is the standard pemergency rom, and I have only used roms that are recommended for my version of the device. I know not to use roms that are meant for the wrong device on my tablet.

There could be an error with the MTK tools, but I would not know where to look.

I'm not sure that I have any NVRAM backups, and I can't remember where to check for them, as I have changed files around several times, and cannot remember what went where.

I would be grateful for any pointers you can give me, syserr. It is not my primary device, so there is no great hurry to fix it, although it would be nice to have full functionality on it for when I need it.
[Android General] syserr:
You'll want specific drivers that allow SP Flash Tool to talk to it, not all drivers do.

I've had good luck with two sets...

http://xdaforums.com/showpost.php?p=40722017&postcount=1466

In this post way back, these are the original drivers on my AT&T -H. The "Files" directory has an *.INF file that should be selected each time.

Another route is search for "VCOM USB".

Update: and yes there is yet another route ursulavasey mentioned the pda.net drivers.

The first option though should have all that was ever available from Lenovo. BTW, I didn't have good luck with the .exe to install the drivers. I had to wait for it to prompt for where to look and then point it at the *.INF each time. It took about 5 times to get everything loaded.
[Android General] syserr:
Look for your old nvram backup. It could be named nvram.tar or a folder called nvram, and could be on your PCs HD or your sdcard depending how you backed it up. Also look for this file: MP0B_001

First I would grab a copy of your current nvram folder at least for safe keeping.

I'd try google search for "MP0B_001 mtk"... 4 links that look promising:

A long path, might be find a comparable -H SPFT backup... flash the whole dang thing, even the NVRAM, then use the imei.exe program to create a new MP0B_001 file and push it into place on a running system.

[Android General] jittusm:
My prob is that my 2107a-h is bricked and i can only access adb through factory mode (Power+vol up) and there too su is broken in adb. Which mode shud i be on for SPFT to work? cos SPFT is not recognizing my tab in factory mode or stock recovery. i dont have CWMR. i have working VCOM drivers. any help is appreciated.
[Android General] syserr:
If it's your file and not someone else's that you downloaded, then you should be in great shape.

Have you used ADB before? Or SP Flash Tool?

SP Flash can push the nvram.img to the NVRAM partition at a very basic level. (before ANYTHING boots, in Meta Mode)

You could run adb while the tablet is booted in to Recovery. Then push the nvram.img to your tablet. Then use "dd" to write to flash.

If you feel more comfortable with one of those than they other, I can help you further. If you can get the USB VCOM drivers working, then SP Flash Tool is probably easier and less error prone.

---------- Post added at 10:29 PM ---------- Previous post was at 10:17 PM ----------

I've only used adb while booted into recovery or main OS, interesting about factory mode.

SPFT is the big gun. You can definitely push ClearSky rom with SPFT to your -H. You can find links to the zip that contains ClearSky in my FAQ (link in my sig). And absolutely you still have Meta Mode to go back to, as I've said it is there before any OS or even bootloader. SPFT will talk to your MTK device in Meta Mode. To get there press reset (with a pen), while holding reset press UpVol, then release reset, then release UpVol... SPFT should see it at that point. SPFT is kind of stateless -- you start an action without it talking to your tablet and THEN make the tablet go into Meta Mode for SPFT to see it. The VCOM Drivers should see it, they may prompt you to install more devices since Meta Mode will look like a different device from the normal USB/ADB connection.
[Android General] jittusm:
Thanks for the reply.. with ur help i cud access the SPFT and formatted and flashed the recovery but the tab is not booting up. and the ROM u mentioned i cant flash thru SPFT cos i dont have its scatter file and to create it via MTK studio i need firmware.info which i cant find. what shud i do?

Looking for Urgent help regarding Lenovo Ideatab A2107A 16GB

Hello Everyone,

I am looking for a urgent help from anyone of you who can guide me properly to recover my lenovo tab into working format. I have Lenovo Ideatab A2107A which is 16GB. Couple days ago, i rooted my device and install a custom ROM named as preemergency by makbro. Just 2 days ago, i tried again to install a fresh copy of the ROM but accidently, i didnot keep any backup on phone internal sdcard. So,right now when i tried to open my device, it was stucked on the first Lenovo logo and then nothing happeneds. Also, i am trying to recover it by accessing recover mode by using CWM recovery mode.But in CWM recover mode, it shows that there is no file available in the device to being resotred. Sometimes, it shows can't mount sdcard or sd-ext. Tried to restore the ROM from external sd card but it doesn't able to locate the ROM file. Please, help me to make my device active again. As i am at the begginer level of andorid system, so a st\ep by step solution will be very helpfull for me.

You can't run cm in it unless cm ported it to this device.
[Android General] syserr:
What I remember is some of the drivers are only good for SP flash tool and others work with ADB. Obviously, using one that works in both would be best. See FAQ.
[Android General] syserr:
According to makbro and others foxtrot and lewa are best. Clearsky is good for SP Flash Tool back to a working system, then you can replace recovery and go to foxtrot/lewa.

I believe ClearSky is older.

To add to what lambofgod13 said...

From what I've read it is "impossible" to port Cyanogenmod to MediaTek 6xxx SoCs... but someone did it. So I think we should assume it's pretty hard. But maybe there can be piggybacking on that effort.

---------- Post added at 08:30 AM ---------- Previous post was at 08:20 AM ----------

I think you have a few things to try.

1. do reset to factory data/cache.. totally clean.

2. tweak settings - makbro had some recommendations way back in this thread

3. try a "custom" rom

If you can't boot to system and you don't yet have a custom recovery... then your only choice is to flash a recovery with SP Flash Tool. I'd recommend CWM, I don't have experience with TWRP (yet).

[Android General] syserr:
That video shows the current state of your tablet? I think that is a "boot-loop." Are you holding anything down to get to that boot screen? The FAQ I've made, shows how to get into Factory Mode (not very useful), Recovery Mode, and talks about Meta Mode. If you aren't doing anything special to get to that screen, then it's just trying to boot into your (normal) system. But you have other options.

Can you get into Recovery? (Any recovery?)

It is hard to use SP Flash Tool correctly. I'm wondering if you got to the point of seeing the progress bars move during a download/write function?

(We'll get you fixed up eventually.)
[Android General] Cristian.Ene:
Nothing is held down for getting that boot screen.

Honestly, i haven't tried recovery to this moment,.. i will! :)

[Android General] Ultimasta:
Lenovo Freeze/No Homepage?

I apologize if this is an easily fixed issue or has been talked about in the past 190 pages.

Here is a brief rundown on my issue/situation:

- I am a new member although I have read some of this thread before I messed up my tablet

-I probably shouldn't have been doing what I did since I messed up and now I'm at the point of sending it in which requires $ and

it is/was rooted

so idk how that would go down.

Issues:

- I can only turn on my device, either in factory mode and then through a factory reset, OR by turning off and then turning on while plugged into a usb slot so that it unlocks onto "USB Storage screen"

- I can only turn off through reset on back, IF it gets to the main issue.

Situation:

So, I was trying to fully customize this tablet after finally rooting with Root With Restore (no restore available....) and I downloaded GO Launcher EX from the Play Store. I was enjoying the themes and tired of the android (running on stock rom) asking me which app to complete my "home" task with. So I went in to sweepcleaner or w.e. task killing program I had, and deleted/uninstalled the Idea Desktop Launcher which was the devices basic desktop, since GO Launcher was set to default (as chosen).

Now here is where it gets stupid. Thinking it may clean up some space, I chose a factory reset. Upon completion, my tablet did appear at first glance new and normal. When I try to unlock it and go to the home screen, it freezes, and gives the error "System UI is not responding", "Close/Wait". I normally choose wait since at this point I have acces to the default "dock" with the "Back/Home/Recent" and clock/date widget which can get me to system settings.

So, I tried putting the GO Launcher.apk into the download folder and other random folders while connected in USB storage, but that doesn't do me any good. Tried all factory reset options to no avail (youd think itd come back but i guess not)

Is there anyone who knows how to guide me through fixing this issue within only USB storage to a computer, Tablet's system settings, or factory mode? Or does it need to be shipped to Lenovo? If it needs shipping and they notice or informed its rooted, i know that pretty much voids the warranty. Any advice at all?

p.s., would loading a custom rom fix the issue? is there a way to do that if i cant install apps...?
[Android General] Ultimasta:
Can only see system settings and Gmail: FIXED!

So I realize I'm replying to myself but I am doing so in hope it may help others in their future. After attempting the same restores and continuing browsing the gmail and system settings (only apps that worked). I tried something I should have tried sooner. Since I had access to my gmail, I sent myself an email containing the go launcher.apk and installed it from gmail! BAM problem solved, no waiting in mail for device i might not get back or have to pay for! SO FREAKING HAPPY I COULD ..... idk.... BUT HELL YEA! lol

i have question what does CWM do to tablet?
[Android General] Ultimasta:
I would also like to know. I know most people will have the attitude to self educate on the matter but now that I have the tablet back up and running with GO Launcher EX app (cyanogen theme) for the desktop/theme launcher, I am finding all these apps for widgets and tools to improve the speed, browse files, etc.

Since I am also fairly recent to tablets, rooting, and custom roms, I was wondering if an educated member may be able to help guide me through a few basics.

My original plan was: 1) Root A2107A-F (done), and then 2) Learn about and install the popular cyanogenmod rom. I did look into this a bit on the cyanogen site, and was unable to find one for the device, and ended up settling on the theme (lame) for the time being.

I took this another step further an found this thread regarding A2107A-F Roms:

http://xdaforums.com/showthread.php?t=2213225

But my issue still remains, I already messed up my tablet and deleted both google services framework which is apparently build specific and many people say flash a rom (still new to me, tried all the other so called Google Play Store fixes), and when a few posts ago I deleted the Idea Desktop and followed up with a factory reset....

So I am stuck downloading apks from non google market on computer, stashing as attachment in email and sending to myself. (Haven't used google drive yet). The whole point being I need help with the roms OR framework.
[Android General] syserr:
I'm going to have to put better information in the FAQ.

I'm a big fan of Cyanogenmod too, but don't wait for it. I'd bet against a usable CM10 on this tablet. As I've mentioned this week on these forums: I've read that CM is not ported to *any* MediaTek chips or at least the 6xxx series. Apparently someone got it working on a phone though. UPDATE: There is some work on getting CM on MTK devices, like on the Oppo phone. This could be helpful.

Rooting gets you only so far. You've seen that it allows you to break your system. ;)

You probably want a custom recovery in place of the stock one. CWM (Clockwork Mod) Recovery is popular and works with your tablet. This recovery system would allow you to:

1. Reflash to stock or custom rom using someone's update.zip

2. Backup/Recover your entire ROM so when/if you break it by removing things you have a painless way back

There are various ways to install CWM. If you choose to do this, I can explain a few paths you might take.

If you install a custom recovery it only over writes your recovery partition, this won't over write your os partition. But it DOES give you the capability.

---------- Post added at 11:35 PM ---------- Previous post was at 11:31 PM ----------

You should probably ignore factory mode.

Does your device have a GSM SIM slot (the -H model)? Or just Wifi (the -F model)?

Do you have a working CWM?

These are unbrickable.

Remember to get to recovery / CWM, it's not Power+VolUp, it's Power for 3 sec release, then VolUp and VolDown at the same time for 5-10 seconds.

---------- Post added at 11:48 PM ---------- Previous post was at 11:35 PM ----------

Hi,

To my knowledge the -H and -F models have different CWM recovery images. So you need to grab the right one. (I may test the 5 or 6 I have on both units tonight and post them and results.)

Then it seems people use a few different methods:

1. MobileUncle.apk

2. adb shell + dd

2b. rootshell terminal app + dd

3. SP Flash Tool

4. and possibly MTK Droid Root & Tools (but I think it just builds the recovery image from your boot image)

I suspect MobileUncle.apk + the recovery.img of your model is going to be the quickest and least painful.

UPDATE:

CWM for -F

CWM for -H

MobileUncle.apk

I have not tested MobileUncle.apk yet

What doesn't work? You can't get the tool to read your tablet at all? Or your MEIDs are not retrievable? If your MEIDs are not retrievable, you probably need to blow a new NVRAM partition onto your flash, then fix the MEIDs with MKDRT.

SPFT is VERY VERY VERY picky.

If you download the appropriate *SP.7z ROM, and have SP Flash Tool installed on Windows... then you are have there. Next, you can't rename the scatter file or move files around. SPFT DEMANDS that certain ROM files be in the same directory as the scatter file -- this is why I say don't move files around.

[Android General] syserr:
I'm not knowledgeable about 3G SIM on this. (I have a -H single SIM tablet, but I've never put a SIM in it) I encourage you to try your SIM in another tablet (maybe different model) to make sure the switch works fine. Almost all my experience is with CDMA in the US, and now we are just getting 4G LTE SIMs here in the last 2 years.

Question:

Does your MEID show up in the LeWa rom? Also, I know some of these ROMs have a SIM Utility -- I have not run. Is it your understanding that you just plug your SIM in and nothing else needs to be done? I don't know.

From my perspective, if you have a working ROM (LeWa) and you copy the original contents of your /data/nvram folder over the top of it, then it should work. I have heard you might need to reboot and let it settle though.

Perhaps ursulavasey can clue us in? She is the most recent helper for -H (2 SIM) issues.
