In the Vodafone -H ROM I had reboot-from-recovery.p I have renamed that and added .bak in the end.

Rewrote recovery cwm and it kept it.

I tried the NVRAM tweak... didn't worked for me... I have made a backup of NVRAM with MKTDroidTools, and then used the bin file to write the nvram.bin from backup to write it back into the device, restart, but still the nvram wifi error is still there.

No more time to play with it... maybe later.

Thanks

Sorry, but have you read what syserr wrote? You can't install that version if you have the dual sim.

Now, do you have the root on the tablet? If yes or not, doesn't matter.

Follow instructions in this thread

http://xdaforums.com/showthread.php?t=2044496

first post. When you've done you will have the tablet rooted, with CWM recovery installed.

After that you can install a ROM that enables the phone section.

For example this one (Foxtrot 101)

2) copy the zip file (no extract it) in the external sd

3) put the sd into the tablet

4) switch ON the tablet in CWM recovery

5) select wipe cache, dalvik cache, factory reset

see menu

wipe data/factory reset

wipe cache

then go to

and then

wipe dalvik cache

now go back and select

install zip from sdcard

Jelly Bean Rom for A2107A?

So has anybody even been working on a Jelly Bean Rom for the Lenovo Tablet? I think that it would be a necessity knowing that Kit Kat has already been released for other tablets and we are left in the Ice Cream Sandwich age... If we could get it done, I think that it would be the best thing that ever would happen to this tablet. So please if someone could start on it, or think about starting on it. Thanks :D And thank you sysser and that other guy for the links to the rom stuff. :highfive:

MediaTek SoC are a pain!

It is just barely becoming possible to compile ROMs from source for MTK chips, and that is what is needed. This older vintage hardware does not have a supported (MTK) devkit for newer Android versions.

There is some good work going on. I don't have time to break ground, but I'm monitoring the ability to compile JB/KK for MTK6575 and MTK 6577.

Not sure if your problem is resolved. "empty" maybe that means you have a clean ROM with nothing you had installed or saved. But if you mean your flash is empty and now you need to install a ROM, then let us know. ;)
[Android General] syserr:
You must have an A2107A with enough flash, can't remember if it requires 8GB or 16GB.

You also must SPFT Format before writing the SPFT ROM. This is because the block/partition layout for the Vodafone is different. It includes a FAC partition just like the A2107A-F (without SIM) did. The FAC partition bumps down (+1) all the other partitions.

I still have another Tablet here, same Model with Stock ROM

Can i backup the Stock ROM from the "good" tablet and bring it to the "bad" tablet?
[Android General] syserr:
Yes, easy. SP Flash Tool has "Read Memory" and "Write Memory". You can Read the whole flash to a file on your Win PC, then Write it all to the target tablet. I've described this at length in at least 2 posts... search "syserr read write memory" ... it looks like most of those posts are in my FAQ.
[Android General] seven21075:
Thank You!

This. Post#3?

f_orum.xda-developers.com/showthread.php?t=2444967

Ill try it.
[Android General] syserr:
Exactly.

Remember though this copies all the partitions even the one called "NVRAM". NVRAM hold the MEID and WIFI MAC. So by default you will duplicate these values too. Copying/Using the NVRAM partition of another ROM will probably not work well, as other values in the NVRAM partition or specific to certain kernels... like backlight, volume, GPS calibration stuff. The user tools (like Mobile Uncle and MKDRT) to set the WIFI and MEID in the /data/nvram folder do override the NVRAM partition, so you should probably use those to make sure you have something unique.
[Android General] seven21075:
Thank you for your advice :)

Ive already backuped the NVRAM folder. :)
[Android General] seven21075:
Do I need a certain scatter file for my model?

If yes. Wich one of this is it?

d_rive.google.com/folderview?id=0B8PcIZoLeGNuVE8tYmtUbFMteDg&usp=sharing
[Android General] syserr:
This is a great misconception that it seems MTK Droid Root Tool and users seem to be under. Backing up the /data/nvram folder is different than getting an image of the NVRAM partition/block. I've said this many times, but I am only one voice.

Sure, you can backup /data/nvram and restore it... but the underlying NVRAM partition/block does not update depending on that -- it stays old. And... when you do a "factory reset" which wipes DATA partition/block then there goes your /data/nvram directory and you have to restore it or doctor it up again. :( My advice to all... do a Read Memory on your whole ROM before you do anything. If that is too big and painful, do a Read Memory on just the NVRAM block... archive it a way.
[Android General] seven21075:
3. Grab a -H scatter file with accompanying block images

Wich One of this should i use? (16GB Model)

[Android General] seven21075:
Edit.
[Android General] syserr:
If you are using the "Read memory" feature of SP Flash Tool, then any scatter file will do. I know it doesn't sound right, but the reality isn't it shouldn't even need a scatter file to read raw memory... the software just requires it for some reason.

Edit: OK... I should back off that claim a little... It may want to know that the chip is a MT6575, so I'll say any MT6575 scatter file will do. ;)
[Android General] seven21075:
Hi,

(nearly) everything works so far.

But.

Ive very heavy sound issues and i dont know why. Ok i deleted many useless apps with Titanium Backup. But i did that on nearly every device ive ever used and never received sound/audio issues because of that.

https://www.youtube.com/watch?v=RwgutRBtglo&feature=youtu.be

Sorry, but it is not very noisy :( i cant activate full volume. Sound options are completly bugged.

Is there anything i can reinstall to fix that?

The problem is not only in VLC. It is even when i type, when i shutdown, it is everywhere.

When i go back to the previous ROM SE_A2107A-H_ATT_A404_SP the issue is solved.

Maybe i should stay with this ROM :( but what annoys me about it is that i always get a new

MAC Adress. Its seems to be impossible to have a fixed Mac Adress with this SE_A2107A-H_ATT_A404_SP ROM.

I tried to add a new MAC manuelly wit Hex Editor. I set the new WIFI file read only. But still doesnt work for long.

The a2107a where i got the ROM originally from has no sound issues.

Can u help me to fix the sound issues or to fix the changing MAC adress problem?
[Android General] syserr:
I'm 90% sure, your volume calibration works (or doesn't work) depending on the NVRAM partition/block. So the "volume bits" found in SE_A2107A-H_ATT_A404_SP's NVRAM must be compatible with your hardware.

I've tried changing the MEID in the NVRAM block with a hex editor and failed. You can do it with AT commands though, which I think just changes the /data/nvram files rather than going upstream and tweaking the NVRAM block. The MAC can be set (I think) in Mobile Uncle. You could restore the NVRAM that works after you install the ROM you like -- and see if that works.
[Android General] seven21075:
The gives me a permanent MAC but brings the Audio issues.
[Android General] syserr:
Hum... which NVRAM are you doing this with? And it apparently doesn't match the flavor of your A2107A-? ...

A2107A-F

Hello,

A few months ago my tablet's touch screen quit working. I rarely used it and so it seems strange that it just quit. I have reset it multiple times and I have performed a factory reset through the recovery. Nothing seems to be working. Has anyone encountered this issue and found a solution aside from setting it?

I am going to install a new ROM and see if that works. Any advice that you guys can lend me would be greatly appreciated and helpful.
[Android General] syserr:
I haven't heard of others with this problem.

If you are going to install a new ROM for the -F, I'd try the one I made for SPFT. First get a good backup of the NVRAM partition (not the nvram folder). I prefer grabbing it with SP Flash Tool. It hold calibration data and your WiFi MAC address.

Also, this very data (NVRAM partition) could be what is corrupt... as I believe it has touch screen calibration.
[Android General] rantrav:
I'll have to hook it up to my computer and see if I can get a connection through ADB. Other than that it is pretty much done as I have tried everything else. I thought about just redoing the entire system and seeing if that works; I guess the same as you suggested. It is just weird that it randomly quit. I have a Nexus 10 that I use as a tablet now but I do miss having the smaller one for reading, etc.

I will treat it as if it were bricked and see if I can fix it from there. I will post my results in case anyone else ever has this same issue.
