Vodafone Smart tab 2 (Lenovo A2107A) - Swap SD

I couldnt find a dedicate thread for Vodafone Smart tab 2. So I guess I ll post this here maybe will help some people.
This tablet is basicaly a Lenovo A2107 (A2107A_A404_010_002_120913_VODA)
- with single sim slot ( call feature restricted - only data enabled) and 4gb storage (1.8 gb user available)
For root - you can use http://forum.xda-developers.com/showthread.php?t=2044496
User isyrider managed to install recovery and pemergency rom unlocking the calling feature also.
I was looking for a way to swap the internal storage with the sd card so I could get more space if posible without installing a custom rom to avoid incompatibility issues that could appear. Directory bind can help with big game files like gameloft but those 2 gb are still not too much . I was unable to install N.O.V.A 3 because it requires 1.81 gb free on sd.
Anyway long story short . To swap internal memory with SD card you need to have root and replace your VOLD.FSTAB file from system/etc with the one I attached.
You need to have root .
Use any root explorer.
Unzip attachment
Rename your VOLD.FSTAB to VOLD.FSTAB.BAK
Copy my VOLD.FSTAB to system/etc
Reboot.
Check in settings, You will see your sd card listed as internal memory.
This combined with link2sd app will give you plenty of space to install anything .
Hope this helps .
Hi icrazy, I've tried this procedure but unfortunately, I wasn't able to copy your 'vold.fstab' to the directory 'system/etc'. I've rooted my unit before I did this. Now the unit cannot detect SD card. I cannot rename/copy/move any file on this directory. please help... How to restore it, Thank you in advance
Hello, I don't understand what happen. If you were not able to copy my vold.fstab what did you change ? I ask this because you must have done something if now is not working.
Anyway it looks like is a problem with your file explorer , make sure it has read /write rights for system files.
Can you please share some light on isyrider? what is that? where can we find it? Google search didn't seem to help me with this
Is there any way in unlocking the phone feature without installing a different ROM? The last time i did that, with another lenovo tablet, i lost my 3g capabilities , and honestly i don't want to repeat that thing allover again.
Thank you icrazy, working perfectly
I have now 2x Vodafone Smart Tab II 7" with 4 GB and 8 GB storage on internal memory
Hi i managed to use the vold.fstab and replace the internal memory with the sdcard but my problem wasnt solved because the tablet also has another partition 503mb of internal storage and when i install any app will install the apps data on that internal storage even if i have sdcard or internal memory as default write disk so after a couple of apps i have the out of space issue because the internal storage is full is there any way to swap the internal storage 503mb ( not the internal memory 1.85gb) with the internal memory or even with the sdcard this is really stupid why have only 503mb of internal storage if the apps save keep saving data on that partition
Regards

[Q] Acer Liquid E2 shows I only can move1,65gb apps2SD while I put 8gb card, why?

Hello,
because there is no specific forum section for this device I ask my question here, I hope the mods can move it to the correct forum section...
Yesterday I bought a brand new Acer Liquid E2, I love the phone but there are problems!
First: I put a 32gb MicroSD card in the phone and it crashed and now my 32gb MicroSD card is damaged!
Then: I put a 8gb MicroSD card in the phone, it has recognised the card but when I try to move apps to sd card the phone shows that it has only 1,65gb memory while I have 8gb MicroSD capacity!!!
Can anyone tell me for God's sake why the hell I only can move 1,65gb apps on SD while I have more memory!!!???
I hope we can fix that problem otherwise I will turn my phone back.
Thanks in advance

I have an acer liquid e2 and encountered that problem to
the problem is that you only can move apps to the internal SD-Card
there are 3 different memory "cards" on the acer e2
4gb internal memory splitted in two parts
- 1.65 gb usable as internal SD (sdcard0)
- and the rest is the internal memory for the android OS and other stuff
Your external SD card (sdcard1)
When you move apps to sd it will automatically move them to sdcard0 wich is only 1,65GB
somwhere
There is a way to switch the sdcard0 and sdcard1 so you can move as many apps to your sd as it is big but you need root to do this
rooting the acer liquid E2 is still a bit experimental but soon everything will be possible with our E2 its an awesome phone for the relatively low price so don't turn it back so soonsomwhere
I saw this somewhere on a french android forum will post the link if i can find it
Hi,
An official update from Acer is on its way to allow external SD to be used for apps. Should be there soon.
Root is not experimental it's very easy to do and you also can get CWM recovery, a way to swap internalSD and externalSD plus a way to extand internal memory (won't be necessary when Acer releases its update).
I have all this written in French but lack time to translate those in English. Don't hesitate to go to the forum request thread so XDA opens a forum for the E2

Has this update (ability to move or install apps to ext SD card) now available? Can someone provide a link, please? I tried to find it in Acer's web site but found nothing.
Thanks!
It's being distributed as an OTA update so you're phone should warn you of the availability (unless you're rooted).
I have the WW_GEN1 version available here . Just copy it to SDcard and flash through recovery.

[Q] HELP! Micromax Unite 2 | Data not geting saved on internal memory

Hello!
I am using Micromax Unite 2 with Official ROM (Read Back of my own phone) (ROOTED)
Recently i have Upgraded back my Firmware to Official one, before that i was using
My Phone Rio Lite Jelly Bean on my phone. Everything was fine till then.
After i revert back to official Firmware on my UNITE 2, i am not able to download any data o my phone memory.
I have Repartitioned my internal memory as to get more App storage space. in setting whether i select Internal Memory or External SD card
my data is getting downloaded on my EXTERNAL SD CARD only.
after searching on this topic over internet i came to know to switch internal memory with external modifying vold.fstab
but i cant find it in my ROOT folder.
Please help me out of this !!!
did you flashed the stock ROM or you restored the Previous Backup you had ?
Is it 4GB or 8GB version ?
If possible try to Re-partition for once using the EBR files from kiran anto, See the video in my signature for links.

I have Flashed the STOCK ROM from SP Flash Tool.
its a 8GB Version.
its certainly mis-match of blocks.
try flashing new EBR files of any size and see if it gets fixed.
There are posts elsewhere that stock ROM available elsewhere was having incorrect memory blocks mapping and even lead to a Bricked Device.
