[Q] Lenovo A2107a-F won't read microSD - Android Q&A, Help & Troubleshooting

Hello everyone! I hope I can find help here and I hope I don't get my post deleted. If this is not the most suitable forum for the subject please tell me where I can post it.
My Lenovo tablet started to have problems reading external microSD after someone extracted the MicroSd card from the device when it was turned on, that was some time ago, but suddenly yesterday it stopped working, I rebooted but it didn't work, after some "research" on the internet I found out that "vold.fstab" might causing problems. At that moment I could access internal memory through any file browser, but I decided to edit "vold.fstab" and after that even Internal memory became inaccessible although it installs apps and works more or less "normally" then I tried to restore factory settings, it didn't work and if tried to connect to a PC (just trying to restore the original files) simply it won't load on the PC. Is there a way to restore the original files(vold.fstab, vold.ftsab.nand)? or is there a way to find out or test if there's a physical damage?
Sorry if my post it's a little bit long or if my redaction isn't the best. Thanks :good:

[Q] Is there any way to ignore the internal SD memory in Samsung GT-I9003?

Hi everyone,
First things first, sorry if this was covered somewhere else in the forums, I really didn't find this question anywhere so I "had" to post this.
I got my Samsung GT-I9003 4GB a month ago, and everything was working perfectly until 3 days ago. It starts showing an "Internal SD card unexpectedly removed" error whenever the phone goes standby, then it forces me to terminate processes one after another, and finally it shuts down. I hadn't done any kind of ROM flashing nor rooting the device until the problems arose, so I don't know where the problem comes from.
I've tried to re-flash froyo 2.2.1 in my device, but the problem keeps showing up.
I found in this forums this thread (http://forum.xda-developers.com/showthread.php?t=1088474) covering the possibility of swapping both internal memory and external SD. It works great, but I still had problems with the "external SD card" being "unexpectedly removed"...
It crossed my mind if it was possible to modify the vold.fstab file further to only detect the external SD card as the internal memory and ignore the internal memory, as if it wasn't even on the phone. I don't know if that's even possible (since I don't know much about file systems nor Android), but I'd appreciate your thoughts on the matter.

Was having the exact same problem with a further twist, the issue occured almost every half an hour at office and very rarely at home. Tried a factory reset and also GB update via Kies. Problem was still present, so have given it to samsung service and the service rep informed me that it was most likely a motherboard issue.
Recently one of my friends had the same issue. Samsung service center replaced the motheboard and the issue seems to be resolved.

[Q] SD card is full (but, its not)

Hi,
another forum recommended I register and ask my question here. I am not a techie. I don't know what I'm doing. This is probably a basic question, but with all the googling I've done, I can't find the answer!
Here goes, and please be easy on me:laugh:
My GS3 was running really slow, running down the battery, just in general not running as well as I remembered from a year before buying it. I decided to back it up, reset it and start from scratch. The phone has run AWESOME! One problem though; when it updated, it installed 4.3. Ever since, I can't do anything with my SD card. I get an error that the SD card is full, and if I look in the settings, it shows zero space on the SD card. If I plug it into my mac, it shows like 12gb of space.
I used to use Android File Transfer and that doesn't work anymore. I recently tried Airdroid, which works great for the internal storage, but tells me that my SD card is full.
Help!
PS I tried to post a link to a screenshot of what storage on my phone looks like, but since I'm a noob, I'm not allowed
When you upgrade to android 4.3 it will change your storage partition from sdcard0 to emulated/0 ... simply it will change its partition so all your old files will not be visible there but they are still in your memory... I suggest you find your old files and move them to new directory... There are many threads on how to find your old files.. Search

[Q] Please help, Phone is badly messedup, Cannot mount SDcard or reinstall rom!

Please please help me, I know it sounds pathetic but im nearly in tears due to how massive an impact this is having on my life!! :'(
Im willing to genuinely pay £10 via paypal to anyone who can help me fix my phone, I promise.
My phone is an LG Gt540.
I bought it 2months ago new on stock rom.
I managed to workout how to root it, and then upgraded its rom a few times over the next few days.
I eventually reached CM 4.2.1 rom, which is the highest available and worked well.
The phone has only 133mb internal space though, and so I needed something to increase the storage (using my SD card's space).
And so after many days of trying stuff I managed to find Mounts2sd.
I partitioned my SD card correctly (using mini partition wizard), and mounts2sd was working fine.
However 1 app didn't work, and so like an idiot I decided to re-flash the entire rom, wipe the sd-card, and try to restart from fresh.
However I endedup formatting; the SDcard, The SD ext, the System, and formatting everything in the menu in recovery.
The phoned bricked and wouldn't turn on.
But I managed to put my SD card in my laptop, have my laptop detect it as a 'device', and so was able to place the ROM file onto the SD card that way.
I then re-booted into recovery, and re-installed the rom.
I thought id fixed the phone, but clearly I hadn't.
And for the last 2weeks since, everytime I try to re-install mounts2sd, it just totally screws up and freezes up the phone.
I partition the SD card correctly each time, however when checking it in recovery it says SD-ext wasn't ever mounting (error mounting SD-ext) was the exact message.
I then tried to re-install a lower level rom (2.3.4 I think it is) onto the phone,
to then re-install CM 4.2.1 afterwards hoping that that would fix it all,
however the phone now wont detect the SD card at all!! :'(
The only way I could access the SD card normally is put it in the phone, plug in usb cable, it wont ever detect the SD card as a folder on my laptop like C: or D:, but if I use Mobile2go software from wondershare I was able to connect to the phone and access the SD card from there, and transfer files onto it that way.
However I now cannot do that, since when I try the phone will turn on but has error msg flashup every second saying something like keyboard has stopped working, and so it wont load the Mobile2go software, and so I cant connect to the SD card to put the 4.2.1 rom onto it.
I have tried placing the SD card into the laptop through the side-slot thing, and can access it via mini-partition wizard when I do that.
However the SD card is not being detected at all when I click on My Computer, and so I cannot place any files onto it! :'(
I seriously am so close to crying now, this has already had me in tears, as its so upsetting!
Please please can someone help me.
To summarise the things I need to be able to do (in order I guess) are-
1. Find a way of getting my phone to recognise and mount the SD card.
2. Find a way of getting my phone/laptop to detect the SD card and allow files (CM 4.2.1 rom) to be placed onto it so I can install that back onto my phone.
3. Find a way of being able to get the SD-ext to be recognised and detected as being mounted by the phone so that I can use Mounts2sd.
If anyone can help me do all those 3 things I will be so truly grateful and will happily pay £10 to you via paypal as a sign of my gratitude.
As this is just distressing and upsetting me so much.
Thankyou
Jessica

Hello and thankyou for your reply.
How exactly do I use 'kdz' to flash back to the 1.6 stock rom though please?
As I don't know any of these technical terms at all.
Anyone have their efs folder contents completely disappear?
This happened to me with my Sprint galaxy S 5 and I get a pop up saying the device is in " Factory Mode " and I need to switch it to user for it to work properly. The phone will boot with a stock recovery only but is useless due to the Factory Mode, it disables WiFi and causes numerous other issues .
Would greatly appreciate any input on this. It is all over the internet but nothing but no legitimate fixes after 30+ hours of research
Look at LG Swift GT 540 forum on xda, there are all tutorials, Now I cant post link for it bu google it "LG gt540 xda"

Help with Firmware+Soft Bricked Unknown Tablet

Hello!
I'm having a problem, the thing is i have a tablet which is not a good one honestly but I only use it to watch videos and download large files, then one day I inserted a new sd card for some file transfer and it turned off, I didn't know at first but it only turned on when I removed the SD card and found out it only worked without it, specifically that SD not my other one, once again I inserted it while it was on but it turned off again but this time it got in a bootloop, I aleadry have gone through this but forgot some of this restore process so I searched abit and it said to re install the ROM with a program (I forgot to mention but I think the SD card reader isn't reading and can't put files in a SD card I have since the notebook I have don't have a adaptator SD and I don't have those USB adaptadors for SD cards either) so I used the tutorial that teaches using a program which installs a firmware again, which would help, I went and downloaded the ROM that said it was for my tablet ( M7s Dual Core ML01 and the chip is called rockchip 3026 or rk3026, in kitkat 4.4 , its made in Brazil by a poor company called Multilaser, so i think the tablet has some kind of chinese origins, anyways, the post helping had the same specifications said by me so I went and installed using the program for it called rockbatch or something like that, but the tablet got a greyscreen over most parts of the brick, its still working as it can go to the recovery screen too but I can't really see it, so I'm wondering what I'm doing wrong or where to find the correct firmware, I tried similar to the name firmwares but same results, now I'm back to the normal one with grey screen and im kinda need of urgent help.

Rooted Moto G Turbo: Can't save anything until rebooting

Hi everyone.
I have a Moto G Turbo with root access. I've had this phone for more than a year and never had any storage problems. Last week my micro sd 16gb stopped working suddenly. I tried the sd in a pc and another 2 android devices and neither worked. I thought the micro sd maybe had it's life cycle complete, so bought an Adata 32Gb class 10 micro SD and formatted as Adoptable Storage. Things worked normally for the day but after a few hours of usage I noticed I could not download photos from any app, neither could take a picture.
I couldn't even save GTA SA. (Different apps had different errors, but the result was the same, save failed)
I tried to create a file within the sd card with Amaze file browser and couldn't. It gave me a message about not having permission. But if I create a file in the root folder, have no problem.
So I restarted the device and noticed the completed download notification from the pictures I tried to save before reboot. The pictures were there as soon as the device started.
This is happening oftenly. Several times a day I got to reboot my phone to save something.
It has been more than a week, I tried searching in many places (not only this forum) but cannot find something similar happening to anyone. Maybe I'm searching the wrong words idk.
Tried many fixes including the modification of plataform.xml and nothing worked.
I don't have idea why this is happening, but I had the feeling that it has to be with supersu permissions.
Hope someone knows something about this or how to trace the problem to it's root.
Thanks in advance :fingers-crossed::fingers-crossed:
