thanks,

i already dit it, but nothing happens. the Screen is black, no logo, etc.

maybe the battery is empty? charging is not possible, there is no charging icon...
[Android General] syserr:
If it will take SP Flash Tool ROMs, it's not dead yet. Be very liberal with pressing the reset button, as was said above.

If you "Download" a firmware onto it with SPFT, if it's one of mine, you should make sure you go and select the block/partitions that are automatically unchecked -- such as SPFT etc. Make sure you Format and Flash the BOOTLOADER now too, since that doesn't seem to be working.

What am I doing wrong?

I have read the forum and thought that it was a root issue but I have not been able to use the external 64gb sd card for my main storage instead of the internal sd. What to I do.? I have tried DS Maid pro thinking that I could just trans fer the files for the internal to the external, no go. I have used Super user to root it and thought that I had but that didn't seem to work either. I downloaded Mounts2SD but it tells me that I need Superuser (root) privileges. I came here for help with it. Am I missing a step or something. I even downloaded Root Explorer but it did seem to work. Ok I need someone to tell me what I'm doing wrong.:eek:
[Android General] mathei:
Try a 32 Gb SD card.:)

If you wont change (if you have a custom recovery) internal SDcard with external SD card, flash zip "Patch main to SD 2"(in attach).

For retry flash "Patch main to SD".

If you damage tablet is your fault!
[Android General] syserr:
I haven't tried to do Mounts2SD.

You should get root on your device though, if these utility apps need it. It's pretty easy, look at my FAQ -- might be down a few posts.

The biggest that the internal "DATA" partition/block can be is 2GB. When I hacked it bigger, MTK kernel freaks out. So that won't help if you want it huge, but 2GB is better than 1GB or 1.5GB.
[Android General] pickled-onion:
I have the Vodafone smart tab II variant of the a2107, seems to be the same as the -H but I've only got 4 gb of internal storage. Or I'm meant to have 4gb, as my device seems to think I only have 504 mb of internal storage. I've tried resetting it every way I know how, and I have absolutely no idea how this happened. How can I get my storage back?
[Android General] syserr:
I'm showing this for the VOD ROM:

~512MB USRDATA

~512MB SYSTEM/ANDROID

So you have whatever is left in FAT... which is formatted and seen as your internal SDCARD. I suspect this is about 2.5GB if you only have 4GB, but I thought VOD had more flash than that.. I might get my hands on my daughter's VOD ST II and verify.
[Android General] pickled-onion:
Yeah, it says that I've got about 2GB on my internal SD, even though I took the SD out.
[Android General] syserr:
Yeah that is your "internal SDCARD" ... weird, I know.

You could increase your USRDATA partition and shrink FAT. The way I know how to do this is time consuming: involves... saving off the NVRAM block/partition... format (with tweaked scatter file), restoring/writing a SPFT-style ROM (with tweaked MBR, EBR1, EBR2 blocks). Restore NVRAM block/partition.

It's not hard, but time consuming. I can help you if you decide to do it.

HELP!!!

Ok, I posted in the FAQ A2107 Forum but nobody will answer me! I have a huge problem, or maybe its small one but I'm not thinking right. I cannot get my tablet to connect to my computer no matter what I do. I restarted the tablet, then the computer, then reset the tablet, then installed a whole 'nother rom and I still couldn't get it to work. I tried installing a different recovery and that didn't work. I looked for answers on the web but no help whatsoever. I deleted just about everything on the tablet and still not working. It shows on the tablet that it has been connected but not to a USB compatible device, all it does is charge. My computer doesn't even make the device connected sound. NOTHING SEEMS TO WORK!!!! I am kind of frustrated right now with this tablet. I have no idea what is wrong, please someone help me! I already tried different cables and different computers but still no go. I really don't want to hear that I have to replace the micro USB port on the tablet or that there is no hope... Please help... :.(
[Android General] syserr:
Hi,

makbro has been gone for quite some time, don't expect an answer from him. As far as cookbooks on recovering, make sure you understand what you are doing. I've tried to explain why we doing things rather than just blind procedures.

I have an A2107A and A1000F. The first thing I did, and probably you should do still is "Read Memory" to a disk. So this is a raw dump of your ROM. This way, you are getting anything that might be left -- if you have the NVRAM block/partition still this will save it off along with everything else.

Then, yes... you can use Format on your A1000G. You'll want a scatter file for it, and associated partition/block files. (Or an entire ROM dump from someone) After a Format though, you really want to restore your NVRAM partition/block so you have your WiFi MAC, IMEI, etc back.

Thz for your help~

Would u mind tell me how to do this?~

Coz i bought a Lenovo IdeaTab S6000-H~

I hope it can make a 3G call too~^^ many THZ~
[Android General] syserr:
Lenovo released several A2107A-H models. All had a SIM slot, some had 2. It turns out that the ROMs for the Chinese version of the A2107A-H had a Phone app and supporting software stack. This was lifted and merged onto some other ROMs. So the original Chinese ROM and the ones that utilized it at Phone/Call capabilities. Originally, no other models came with Phone/Call capabilities, other than the Chinese version.

So... to you... this means you need to find a ROM (probably Chinese region) that has the Phone/Call capability. Then you can flash your tablet with it and use GSM/3G to place calls. I would make a total backup first with SP Flash Tool. This way if your blow away the partition/block that is called NVRAM you can rewrite it later.

[Android General] sverza:
Do you mean that flashing (via SPFT) only the modem.img (so not the entire ROM) and then installing the framework-res.apk (when the tablet is switched ON) the tablet will have also the phone feature available (and working)?

Open device manager and turn up PC volume.

[Android General] sverza:
Try in this way.

Check if there is some activity in usb ports using this program USBDeview (http://www.nirsoft.net/utils/usb_devices_view.html)

To start you can check if in some way there is something not recognised by the pc.
[Android General] priyanga:

[Android General] sverza:
Sorry, it's not clear for me, the pc doesn't detect the tablet when it is already switched ON or also when the tablet is switching ON (i mean: preloader).

And, wich ROM is currently installed on tablet? There was some update before (custom rom, ...)?
[Android General] priyanga:
rom is xnetfox . normally if you connect tab to pc via usb, you will hear sound from pc that some usb is connected. but when i connect my tab to pc no any sound nothing.only battery charging.
[Android General] sverza:
Ok, try in this way:

- switch OFF the tablet

- open devicemanager in windows or SPFT (in this case let the SPFT pending an action, type readback)

- connect the table to pc and switch it ON

- try to see if in this way you see some activity in usb (in devicemanager items should be updated and in SPFT the readback action should start)
[Android General] priyanga:
i tried no luck. i think my 5 five yer old may be delete something.
[Android General] sverza:
Have you tried simply installing again the rom via recovery?
[Android General] priyanga:
yes i installed all the roms in the thread. all roms working good except usb.

i think it will be okay if i flash through spft but usb not detecting.

thanks
[Android General] sverza:
Another idea: have you tried keeping pushed the soft reset button (back of the tablet) for 5-10 secs?
[Android General] priyanga:
i tried everything reset the back button.

finally i sold my tablet thank you for your help.

Please help.
[Android General] DMgadgetguy:
I had the same issue with the USB port charging but not able to get a data connection to a PC; no debugging mode, no media device mode.

I figured I'd take a look to see if there was a loose connection, or worst case visibly see if there was an issue with the USB port itself. I found the service manual (link below), and started disassembling. After carefully disassembling I found that the connection to the USB board was loose, push it down so it was secure and reassemble all the connector and fired it up. Connected to a PC and the tablet made a USB connection in debugging mode. Yay! After looking at where the connector is, I probably only needed to remove the back panel, and the base cover (the one with all the screws) to get to the connector. I realized afterwards that my head phone jack also stopped working around the same time as the USB port, all working now.

If you don't feel comfortable tearing electronics apart, find someone that does.

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 :(
[Android General] sverza:
Sorry, are both vodafone branded?
[Android General] AndroSteel:
Help ASAP..

Firstly, thanks for the fast reply! Secondly, yes and it worked perfectly with my father's tablet (It even got carrier-unlocked!). But, today I verified something. My father's CWM version is 5.5 and my brother's is 6.0¡ I think that's the case, sp you could help me out with flashing 5.5 CWM via SP flash tool. And a good scatter file would be appreticiated. Thanks in advance!
[Android General] sverza:
You can try flashing the original rom (shared by syserr here http://xdaforums.com/showpost.php?p=51405736&postcount=2154) and then doing the same thing you did with the tablet of your father.
[Android General] AndroSteel:
Not sucessful

It gives me the "SET COUNTRY CODE" error.

I did the following on scatter-file, because it seemed not to flash anything:

__NODL_FAC

__NODL_FAT

Now it looks like:

PRELOADER 0x0
{
}
DSP_BL 0x40000
{
}
MBR 0x600000
{
}
EBR1 0x604000
{
}
__NODL_PMT 0x660000
{
}
__NODL_NVRAM 0xa60000
{
}
__NODL_SECCFG 0xd60000
{
}
UBOOT 0xd80000
{
}
BOOTIMG 0xde0000
{
}

{
}
SEC_RO 0x19e0000
{
}
__NODL_MISC 0x1fe0000
{
}
LOGO 0x2040000
{
}
__NODL_EXPDB 0x2340000
{
}
EBR2 0x23e0000
{

__NODL_FAC 0x23e4000
{

ANDROID 0x123e4000
{

{

USRDATA 0x525e4000
{
}

__NODL_FAT 0x726e4000
{
}
__NODL_BMTPOOL 0xffffffffffff0050
{
}

Then it started flashing. It finished flashing (DA/DL enabled) and then booted. It stuck at "Set Country Code" screen.

What i did was booting into CWM (the one i pushed out my father's tablet) and did the /system, /data, /cache wipe (dalvik too) and went to Backup and Restore -> Advanced Restore -> System and then choosed Pemergency ROM. It is stuck at Vodafone logo now. I'd appreticiate if u did some effort to explain me properly the situation or what i did wrong.

My model is 4GB. CWM says "System restore completed!"

Thanks in advance!

Thanks for your time! But i did figure out myself. I knew it had issues with the partitions and the lack of files for them (FAC partition most likely). What I did was flashong Foxtrot ROM with SP flash tool using Firmware Upgrade option and then replacing the recovery to CWM 5.5 (it seems that 6.0 cannot restore 5.5's backups) Wiped all the stuff and used Advanced recovery and choosed System. It worked pretty well. Thanks again!

Lenovo partitions help

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] AndroSteel:
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 :)
[Android General] muse14:
trying to solve the problem, I formated flash and and tried to install the original rom...now Im having the select country loop problem :P

should I install the foxtrot rom again and do what you told me? (I think Ill have to root the tablet again...it seems that I lost the cwm when I installed the original rom)

thanks btw =)
[Android General] AndroSteel:
I see, Country Code error, isn't leading us anywhere. Whatever you chose, it will bootloop. I think it has to do with FAC partition, but i am unsure. Anyway, to flash cwm back, head at csns post: http://xdaforums.com/showthread.php?p=35369121

Download and keep the files of Update 3 at csns post. Then go here: https://docs.google.com/file/d/0B3mEU9NrekE5RzhrTk1JYWZibHM/edit?usp=sharing

Download and extract the zip. Don't use the SP flash tool included in the zip. Use the one you used to format the NAND flash. Before you load the scatter file from foxtrot ROM: Your device must me 4GB, so you need to edit some stuff first. Go to the scatter file and edit with Notepad++. Make sure to put __NODL_ (exactly as its written) before FAC and FAT partitions.

It should look like:

Before: FAC {hexidecimal stuff}

After: __NODL_FAC {hexidecimal stuff}

Now go to SP Flash tool and load scatter file and choose the one you just edited. IMPORTANT: Check DA/DL with checksum and use FIRMWARE UPGRADE instead of Download. You may want to replace the TWRP recovery that comes with FOXTROOT, so choose one from the folder you downloaded from csns post. Press start and then get a cup of coffee, it will take some minutes. After that reboot and woah! Partitions are OK and you can change the ROM with CWM if you don't like it. If the ROM doesn't recognise the IMEI (most probably), you'll have to restore it using Mobileuncle. Good luck!

a2107a

Hi noobie read the posts up to here I have two Lenovo's in our house both the same model both bought at nearly the same time (not bragging) The point is it says use another pc with the drivers installed.

My pc has the drivers installed, if I put the good one in it comes up under android phones and is listed in the disconnect icon as a Lenovo a2170a device.

But when I put the duff one in it comes up under network devices and is a alcatel single rndis interface and does not register in the disconnect icon, so when you use the sp tool and the unbrick scatter file nothing happens.

I have read quite a few posts on this and they seem to agree that VCOM drivers are needed.

Can some one tell me a easily understandable way of installing these drivers.

I have watched some vids on utube but they are out of focus are in a foreign language or they go that fast because they Know how to do it, you cannot keep up with them even using the pause button.

Thanks in advance, hope someone is listening.
