LENOVO a2107-H version with single SIM/ NEED HELP ASAP PLEASE!

Ok.. I've been playing with this device for a long time, but this time i need some help (badly). Here's my case:

Both my brother and my father own this device. I managed to root and flash CWM recovery (using MobileUncle Tools). I downloaded the ROM posted by pemergency. Note as it was deleted from those hosts, but fourtanently someone has had it backed up by CWM. In my father's tablet i just went to Mounts and storage -> Format /system and did the other things: Wiping Data, Cache and Dalvik Cache. After that, i did the Backup and Restore -> Advanced restore -> System It worked perfectly! My father could even call with that ROM. The problems start when my brother asks me to do the same. I did exactly the same things. (I even backed up everything before starting). Formatted system, Wiped data/cache/dalvik cache. But when i go to Backup and restore -> Advanced restore -> System, it passes the MD5 check and starts dumping the files into the /system partition. Unfourtanently, it stops at some point saying: "unable to restore /system!. I checked the recovery.log file and the last lines were something like this: "Can't format unsecure partition /dev/mm..../p1 and p4. I also tried to restore the stock backup i made. It boots me to a screen asking to "Choose countryCode:". I tried all the options but it end on Timeout and then restart.

Also, i corrupted my SDCard, but i have the extracted zip files of system.ext.tar file (pemergency ROM) and I'm able to boot into CWM recovery.

I would really apprentice if u guys helped me. My brother needs this tablet (H version with 1 sim card {3G} locked under Vodafone logo) because he uses it for school. I need a tutorial as soon as possible please. I'm hopeless. Dont hesitate to ask me everything u need. Just give me a tutorial for the Stock, or any other working ROMs (preferably CWM flashable). But i dont mind using SP flash tool. Just help me please!! I really need help :(

Lenovo tab problem

Hello guys

I have a vodafone smart tab 2 7' ...and I wanted to expand the internal storage....but in the process I managed to ruin everything, and now I have the tablet rooted with the foxtrot rom, but I changed so many things (changed sd card partitions on the pc usingminitool and installed a couple of swap to sd apk's)

the end result right, I have 500mb of internal storage, and another 500mb of usb storage (instead of 1+Gb), and this is without the sd card in the tablet, when I put the sd card in, I get the same 500mb of internal storage (normal), 7+Gb of usb storage, and 500mb of sd card

my goal is to go back to normal (500mb internal storage, 1+Gb usb storage, 8Gb sd card)

my main question is: can I revert everything back? is there a way to just install some origin firmware or ROM that changes these partition problems?

i know I probably have to change some NVRAM or some files like that but I could really use help to put everything back to normal

I dont have backups because the tablet was mostly empty and had nothing of value there...

pls help, I dont know what to do right now :S

thanks in advance! and sorry for my english, not native and its pretty late in my country right now

thanks again!

EDIT: I think I switched the size of the /data with the /system ...how can I reverse this?

the sd card being in the usb storage size I think it was because of a swap between them, nothing serious I think
[Android General] syserr:
From my PM, give that a try. Let us do additional discussion here in the public thread.
[Android General] muse14:
I am stuck now on the select a country code loop

what should I do? install foxtrot again with SP? It seems my tablet its not rooted anymore because I cant go into cwm recovery...

on other thread, this use said:

"The truth is that I've also got your Vodafone model. You have changed the partition sizes and this has nothing to do with NVRAM. You must find a proper scatter file to format the phone with new partition sizes. I'll PM you the links as soon as i get to a computer. This should be done with SP Flash tool. And, when you repartitioned your device, you have wiped your NVRAM partition. There is stored hard-IMEI and other calibration data. If mobile networks aren't working you got to use Mobileuncle to write the IMEI. and there's comes the sweet part: your device is carrier-unlocked.

But don't worry, our device is claimed to be un-brickable so almost everything can be fixed "

thanks for the help :)
[Android General] AndroSteel:
Refer instructions provided to the other thread ☺. Also, [MENTION=4796707]syserr[/MENTION] has worked a lot with the set CountryCode error, but like i said, its more complicated. In my experience, it is caused by another partition (probably FAC), because if i backup the whole NAND flash with SP flash tool and restore it, it boots.. If i backup only /system it results in the error.

Hi,

I've got the same issue with my Vodafone SmartTab II after flashing SE_A2107A-H_VOD_SP.7z .

Please give me instructions to proceed.

Thanks.

Edit:

I installed Foxtrot but touch screen does not work.

Can you recommend me the correct firmware for Vodafone SmartTab II?

Thanks again.
[Android General] giorgoslouk:
Nobody????
[Android General] AndroSteel:
Vodafone one won't work. Try Foxtroot ROM and then flash any others using ClockworkMod. Cheers
[Android General] giorgoslouk:
Thanks for the reply AndroSteel.

I've already installed Foxtrot Rerooted and CWM.

The device boots up but the touch screen does not work.That's the only problem that i have.

Can you please recommend me the correct rom to flash?

Best regards.
[Android General] AndroSteel:
You may want to try one of the AT&T ROMs provided in this thread. (It worked for me once) If flashing with CWM doesn't work, then flash one of the first two with SP Flash Tool:

If the drivers of the touchscreen still doesn't work (with the new ROMs), then you might have wiped the NVRAM partition.
But, firstly, focus on doing this, and[B] don't panic[/B], we'll fix that! ;)
[Android General] giorgoslouk:
Thanks for the update AndroSteel.

I've already tried the stock roms but i get the country code selection screen at first boot up and i do not know how to overcome it,since the touch screen does not work and i cannot make any selection.

I'm not sure if the NVRAM partition has been wiped.

When i power on the device with a sim card inserted, i get prompt to enter the pin code.

Anyway, can you give me instructions to restore the NVRAM partition?

Thanks again.

George.
[Android General] AndroSteel:
Restoring the NVRAM is harder than deleting it. NVRAM is not only device specific, but also different in same models. That's the reason why you should have made a backup. Besides that, NVRAM is easily replaceable :D

You will only need the IMEI, and we'll see that later (always, if you have wiped it, of course), otherwise SIM won't work.

Personally, I'm not a big fan of MIUI ROMs, but when it comes to unbrick devices, they just work. It's the last ROM i had for my a2107, so you should have a look and download one that suits you for the moment:

Link HERE!

If you are able to boot from any of these, confirm if you can make any RIL (phone, messages, data).

Good luck!

[Android General] AndroSteel:
Unfortunately, it's probably a ROM bug and thus can't/is very difficult to be fixed/patched because we don't have the source code.

P.S. It may also have to do with gapps. Make sure they are the correct version (for ICS) and update them.

After format and flash the tablet is not powering on

Hi,

I decide to flash my Lenovo IdeaTab A2107A-H Dual SIM, but unfortunately now the tablet won't start.

I follow these instructions but the result is not good. I had 2 options for formatting: 1st - Format whole flash, 2nd - Format whole flash except Bootloader. I format the tablet with the first & second option.

Please HELP!

Instructions:

- Leave tablet disconnected

- Hit Reset button just below camera - now your tablet is cold/off

- Go into SPFT, load up a GOOD scatter and have appropriate ROM blocks. It is VERY VERY picky!

- Go for a format whole flash again.

- SPFT waits...

hello this is a thread started many years ago... I should read for a month all the posts before understanding if there is what i need.

Seeing that there is some one answering in 2017 july i shoud be trust that is still valid this upgrade procedure...

I'm in right?

I received this tablet as gift and is Vodafone Branded,

baseband version is MAUI.11AMD.W11.50.SP.V17.F1.P 2012/09/06

and the build is A2107A_A404_107_055_130124_VODA

I want to install a 5.1 android, unlock call feature and use sd card to install applications seeing that the memory is onlu of 4GB.

I will reach my scope reading all 35pages of threasds?

Thank you

PS Sorry for my english
[Android General] sverza:
I'm not so sure there is the 5.1 version availble for this kind of tablet... probably only 4.x.

In the past I did some checks with the Vodafone Italian version, 4GB, and it worked.

hi, which one is the lightest for h?? is this work good??
[Android General] syserr:
I just tried LeWa and foxtrot, oddly I hadn't tried any others on my -H yet. They seem a little slower, but not too bad. One thing is if you live in a system for a while they always seem to slow down. If you have installed apps and created data in a LeWa and then install my/AT&T rom, I'm sure it's much faster. ;)

I was able to see my MEID in one of the two SIM slot infos in the About Tablet / Status. So I'm not sure why folks with 2 SIMS are not able to see their MEIDs. I hope we can figure that out.

[Android General] syserr:
It seems, I can't recommend my ROM (based on AT&T's ROM) for dual SIMs. I don't have a dual SIM tablet, so I can't really do testing either. If someone would like to do development, I'd certainly try to help.

As far as languages, I think I saw: English, Spanish, maybe French, and Chinese flavors. Unless there is an easy way to slip languages in, then you are probably stuck not liking my ROM. I'm sure there are ways of adding languages from similar ROMs. (sorry)

[Android General] sam_pon:
Dear Vikasdanny

your tablet now does not have all files needed to boot up correctly ,

so, you have to do the whole process as Mr. syserr told you exactly , then after installing a full rom , and the tablet boot correctly , at this point you can install CWM and install any other rom throu the CWM , i hope to hear a good news from you soon .

my great thanks for Mr. syserr
[Android General] vikasdanny:
Got it!!!

:cowboy:

After a lot of tries from the CWM using syserr procedure, i still was not able to find a way out. But, then i downloaded his SP flashable ROMS and flashed it and i am quite happy with it . It works fine now. But NFS MW isn't working properly in this tablet. I got it for testing purposes. I was able to run NFS MW on my htc hd2 but not on this. They both have almost identical specs. What could be the reason that it is not working properly?? :eek:
[Android General] sam_pon:
Congratulation My Dear for the good news ,

i think now the only person who can answer you is syserr , but did you backup your NVRAM folder before format the whole nand memory , and what if you hit about in setting , did you find sim serial and mac address and bluetooth address , every thing is in it`s place .

have a nice day

and wish to you a good luck
[Android General] syserr:
Yeah, throw away that other SPFT ROM. That is 1/2 the trouble people have, they grab a ROM that has not been tested for total flashes etc.

Not sure about your performance problems. I assume you have the -H with dual SIM?
[Android General] Contra1971:
were you ever able to get FM to work, and if so what ROM did you use, and can you give me a link to directions to do it?
[Android General] sam_pon:
My best dear syserr

the real thanks is for you for all your efforts to know about that very important partition which belong to NVRAM , and if you find out how we can re-write this partition by using SP flash tool , it will be so great , because as i told you before that my dealer took about 50$ to fix this part , and he told me that he had to change the whole motherboard , and if you find out how to fix this without changing any thing it means that you made a miracle .

i am really feel that you will make it , because i am sure that somebody with your mind will take it as challenge for him , and you will win

i do not have any thing to help you with except wishing a very very good luck for you , and hope to hear the good news soon .

Well, for the NVRAM block, I am learning.

An option if you have nvram.bin or a nvram.img (from a backup) to restore it...

- go in to the SPFT menus, Window -> Write Memory

- now click the Write Memory tab

- select Open Raw Data, select your nvram.bin

- Choose EMMC

- Start address: begin address 0xA60000

- Container length: just leave zeroes

- Click Write Memory

- SPFT will wait for the device at this point

- if you have the VCOM driver already installed... all you need to do is

- tap Reset button

- Hold VolUp, plug in USB, Release VolUp

Update:

Then make sure the filesystem in /data/nvram is gone so the NVRAM flash block is used:

- Boot into Recovery - Power 3 sec - both VolUp and VolDown pressed for 4 sec

- Wipe Data / Factory Reset

Now boot normal. You should then have your original NVRAM without any hacks applied.

[Android General] syserr:
You're kind of grasping at straws. (an expression)

Regarding Cyanogenmod: http://xdaforums.com/showpost.php?p=46143324&postcount=1951

This tablet has an MediaTek SoC. This is probably the reason video is slower than your HD2.

I'd bet $100 that you don't see this thing run anything other than ICS 4.0.x. MediaTek makes a dev kit for manufacturers for certain chips. The MT6575 was a popular chip when ICS was being developed.

Your best realistic hope for this tablet... Lenovo's 4.0.4 tweaked and tortured, cleaned, and some kind of V6 overclocking.
