Yeah, flashing CWM ROMs will not help you right now. Doing that is just switching out Android, or worse replacing your FAC partition with your ANDROID rom update.

I assume you have an A2107A-H? (and not a A2107A-F?)

Are you familiar with SP Flash Tool?

Can you run ADB (Android Debug Bridge)?

Are you familiar with MK Droid Root Tool? (this one would only give diagnostics, but could help with ADB setup)

We need a bigger hammer to fix your problem.

At this point it wouldn't hurt to try my CWM update I posted a while back to fix a member's FAC partition:

https://drive.google.com/file/d/0B8PcIZoLeGNucXF1WnAtZXc0NUE

That would probably at least accept your selection and say country selection OK.

I've got the Vodafone Smart Tab & II version, which is basically an -H with a Vodafone badge on the back.

I've not used SP Flash Tool before, although I have used odin, I presume from what I've read that they're similar?

Yes, I can run ADB but I have not used MK Droid Root Tool.

I'll try that, and let you know what happens.

UPDATE- I used the file you provided, and it booted fine, it went from cwm straight to the screen you see when setting up android for the first time, maybe the recovery.img I used to flash cwm messed up my FAC partition. Thank you so much.
[Android General] syserr:
3 POSTS! Wow... you were excited. ;)

Awesome, I'm glad I could help. So... I'm 99% sure you have a recovery.img that does NOT understand you have a FAC partition. It is writing ANDROID (/system) to partition #6 which clobbers the FAC stuff. BTW, your FAC partition is now super light-weight as I had customized it. The time it takes to register your country is like .5 seconds rather than 3 seconds. :p

(and sorry I spaced that you had said you had the Smart II) So now I know that the Smart Tab II that I'm getting from UK on the slow boat/plane has that wacko partitioning. GURRR :crying:

The recovery.img for -F understands to write ANDROID to partition #7, but if I remember right it doesn't work with the preloader/bootloader for -H. I may experiment. Currently, I don't have a known good recovery.img for you. You could go over to the dark side and re-partition it like the vast majority of -H, but that requires SPFT and fiddling. Or when I get my Smart Tab II, I'll figure something out.

HELP

Ok, please be nice.

I have 3 A2107s for my young children, we've had them for 10m and they are slowly but surely refusing to load apps.

I need to know if there is a way to update the software. If so can you help me sort them out? In simple terms please.

I really don't want to have to purchase new ones and I certainly won't be buying Lenovo ones again if the can't be 'fixed'.

Any help is much appreciated.

[Android General] syserr:
Hi Dana, welcome. My son is using one of my A2107As too. It's working alright for him, but he's only got 3 months of cruft on it. Having many Android phones and tablets I know from experience they do tend to get "clogged" with use.

One thing that might be helpful is if we new if you had an A2107A-F or A2107A-H?

So, I'd say you have 4 possibilities. You can try them sequentially until things get better, or jump to the end if you are confident, or stop if you chicken out somewhere along the line. ;)

Possibility #1

You could try uninstalling some apps, cleaning things up, and wiping your cache. The only technical/tricky thing here is wiping the cache. You would need to do this by booting into the Recovery mode/image. From a total power off state... Press PowerOn for 3.5 seconds, release, press both VolUp / VolDown for 5 seconds. You should see a picture of a dead Android on it's side and a menu. Use VolUp/Down navigate to Wipe Cache, the press the Power button to select it. I think it asks if you are sure, you need to select Yes.

Possibility #2

"Factory Reset" you can go into the same Recovery mode/image as in Possibility #1, but you could select "Wipe User Data / Cache". This wipes off all apps, so you will loose them. Some people don't mind loosing apps, because they are probably in Google Play Store and easy to re-install. This should save all you pictures etc though, they are on a different part of flash.

Possibility #3

"Factory Reset" but save apps first. You will need to root your tablets. It's not hard, but as far as I know, you need a PC connected with USB to do this. skyinfo claims this was easy: http://xdaforums.com/showthread.php?p=46375014 I wrote my own Linux script to do it, which is easy for me, but not easy for everyone. If you go that route, maybe ask some questions. So after you root your tablet, then install Titanium Backup app lite/trial from the Play Store. Titanium will backup apps you choose or all apps, it's not a simple interface. After you backup. You can do a Factory Reset. After Factory Reset, you install Titanium Backup again... and can restore individual apps.

Possibility #4

If you root it and want to clean off extra Lenovo crapware... You can install CWM Recovery, which is a replacement for the normal Recovery mode/image that I mentioned above. With that installed, I could give you a .zip file to put on your SDCARD and run in the CWM Recovery. The .zip would have a command file in it that would remove some of the crud.

Home this helps,

Hello,

somebody managed to install the EU Version of Navigon on this device with the phone-call enabled Rom pemergency Final?

I tried it several times but it won't let me install it.

I then tried the SE Rom for 1 SIM Model (my model only has one SIM slot) and it worked, made an backup and tried it with pemergency Final again, but it also failed.

After that I tried the India Navigon version, this starts and works, but I dont need the indian area, I need the EU Version.

So I think the EU Version desnt like 2SIM Cards, someone mangaed to start Navigon EU or US/CAN with this device???

[Android General] syserr:
I replied in the other thread. I think the 2 SIM ROMs will work on 1 SIM devices. It appears to work, but I don't have a SIM... don't use them here.

Muhammad,

It's a scary place to not have USB capability, as it's the life line to recovery from various problems. Are you sure it's damaged? You can try the Preloader USB Driver SE_Lenovo_A2107A_VCOM.inf And the ADB Driver SE_Lenovo_A2107A_ADB_USB_Driver_120827.7z .... here: https://drive.google.com/#folders/0B8PcIZoLeGNuWS1JUnA2UXdPYUE

I added some Device IDs in existing drivers to create those ^ driver packs.

That said, I don't know of any root methods that don't involve a PC. I was thinking about working on one though. The payload and commands to get root on 4.0.3 and 4.0.4 MTK are really simple.
[Android General] jensbraun:
Hello Friends, I recently got a Lenovo IdeaTab A2107A-H 16 Gb version that I want to send to my wife in Africa. I would like to have the phone function activated and having gone through a lot of the post about rooting, puting an alternative recovery mod on it and finally flashing it with the desired modded ROM, I became quite desillusioned about the whole thing. I have not been successful at grapping all the procedures needed to have that desired ROM, because the more I read, the more confused I become. Could anyone enlighten me or point me to the neccessary threads where I can read the step by step procedure of getting a ROM with activated telephone function on the gadget?

I was here (http://xdaforums.com/showpost.php?p=37409096&postcount=800) and I liked the FOXTROT ROM.

I equally was here (http://xdaforums.com/showthread.php?p=46201425)

And at neither of the places was a pointer to the procedure. I beg you to bear with me. I have never tried flashing a ROM since the Windows Mobile days and nor am I an android user. I think you would have to handle me like a complete NEWBIE. I really would appreciate your help.
[Android General] syserr:
Those are both good links to ROMs for the A2107A. I know of no better.

Although I'm pretty knowledgeable, I've never activated a GSM SIM so I can't give details of that. (CDMA is more popular here, and I got my -H strictly for FM Radio capability.)

I've flashed my 3 A2107As about 300 times, so I *can* help you with that part. I've been cooking up some kind of final guide for my FAQ, check back tomorrow.
[Android General] jensbraun:
Hello Syserr, thanks very much for your prompt reply. I have gone through many threads, I just can't seem to grasp the procedural steps necessary to get started. I was happy when I came across the thread with Pemergency and the user guide available there. However, the joy was short lived, because the ROM and the tools seem not to be available for download. The OneClick... Rooting tool I found somewhere seems infested with a virus. At least that's what Windows defender on Windows 7 says. Then I read Pemergency is oldskool that the up-to-date ROMs are those found on one of the links I provided above. But, I have not been lucky to find a comprehensive tutorial to put the Foxtrot ROM or the Foxtrot ROM rerooted by you on that gadget. I would really love a complete Howto guide. BTW, my IdeaTab is the version with 2 SIMs. Thank you again for your help.

Dear Syserr

Thanks for your support. I am 100% sure about USB port damaged because nothing will happens on PC device manager nor on my Tablet device while plugin USB cable. I can access my android system recovery <3e> but stock recovery need signature verification. I need your expert opinion to root my device after that i can easily flash CWM recovery via ADB Wifi, otherwise last option is to open tablet and repaired USB board which is dangerous and i dont want to take risk at this point.

Hello Syserr, that was really nice of you to take the time to explain. I really appreciate.

[Android General] syserr:
Some information...

Lenovo I believe makes pretty good "china phones" or I guess you could say good "china tablets." Quality-wise, they are probably the best out of that category. But, they definitely aren't the best phones/tablets out there. When people say "china phone" which I've only heard for a few years now, it's basically a phone designed in China not just manufactured there. A few things that set these apart: They copy each other and they copy top-tiered devices. They are low cost. They aren't great quality. You can usually get them drop shipped from China.

Lenovo is using MediaTek chips/designs. MediaTek has been eating the market from the bottom up. It's cool that they put price pressure on everyone. They are in MANY china phones. They are in many Lenovo phones and tablets. I thought that they high end devices would not have MediaTek chips until recently... Motorola D3 and some others have proven that top end companies will be using MediaTek chips.

That said...

If I buy more MediaTek tablets and phones, I probably won't be buying Lenovo. I think you don't get any better support. I'd buy tablets and phones that are more friendly to the hacking community and have a bigger user base in the hacking community.

The A2107A isn't a very good value any more, except for used. You might find some used around $50US. There are QUAD core processors from Lenovo that are about $120US. And if you go MediaTek quad core on a "no-name" china phone/tablet they are quite cheap -- $90US as of Nov 2013. The one cool thing that the A2107A has -- a 3G SIM. Newer phablets I believe are almost all 4G LTE, so it does still have a niche.

It's a love/hate relationship. One great reason to get a A2107A, is you can't brick them. I believe all flashing accidents can be recovered. I even wrote all zeros to the PRELOADER portion of flash just to prove it to myself that I could still flash and recover this device with "Meta Mode."

Sorry I was late getting back to you. It might have been a blessing, I bet the last thing you wanted is to be trying to recovery a tablet that you were trying to send off.

Do you have a NVRAM block backup from before you rooted etc? It might be named nvram.bin if MTK Root & Tool made it.

If you had that... you could:

write it back (restore) with SPFT

boot into CWM on very first boot and move /data/nvram to /data/nvram.old with ADB

then boot normal and see if a good app like GPS Status works

I think you are asking about OTG support. So far, OTG to give you USB peripherals doesn't seem supported on any A2107 ROMs. :( In a few old posts - people said it didn't have the hardware, but I doubt that... I bet it's a kernel driver issue. And I don't think it's a simple matter of copying the driver responsible for OTG onto the system. I've tried quite a bit to get an FM Radio driver from one A2107A rom to another. If the kernel doesn't have a stub built for it, it seems the driver does not work properly.
[Android General] Alex386:

[Android General] syserr:
The problem is, even if we found the driver... I think there is only a 1% chance it would work.

Devices with MediaTek processors are not supported well in the hacker/development community. Kitkat may happen some day when MediaTek releases source. Right now, the only ROMs available are based on A2107A stock roms, and maybe the Lenovo A750 phone.

Sorry.

Looking at compiling our own ROM from scatch, but it is totally unpaved for ALL MediaTek devices.

OK... You should look at some other threads too. This is a good thread, but many people have moved on and will not be answering. Read the FAQ in my sig and also the SE ROM page.

The very first thing... have you run "Format" in SP Flash Tool yet? you should backup your NVRAM partition block before you do "Format" otherwise you make much more work for yourself later.

Is it bricked, or can you get into CWM? You said you had CWM installed and you can boot into it?

Thank you for the reply, Chief :)!!! Im glad to know someone replied and help me out. I will also read the thread in your sig but currently i am still lost on what to do.

Here is what i got & to answer your question:

1. I did format in SP Flash using the thread posted (http://xdaforums.com/showthread.php?t=1982334&page=191) but i can't pass step no.6 since the Chinese ROM link no longer worked. Any suggestion?

2. I have a copy of the folder NVRAM before i started this mess

4. I was only able to get in CWN after i followed the thread mentioned in #1. I dont know if this qualifies as the CWN since i can see error below and as mentioned, i cant get pass step#6 of the thread. Please see screenshot.

What i am trying to do is to get it unbrick and enable phone feature. I really appreciate your help and if possible, can you give me a step by step continuing from CWM if it is valid. Also, please recommend a good, stable Rom which has phone feature.
