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.

Hi everyone!
I have (what I think is) a huge problem on my phone and after looking in tons of forums for solutions I found that the people here seem to really be able to help me.
I'm new to android phones... So please bare with me...
So I bought this phone in second hand from a friend who was in need of some cash for college (I don't really like to buy used stuff but...), and it came rooted with cyanogenMod7 but I was having trouble cause the phone wouldn't recognize my sd card and I couldn't connect it to my pc so I tryed to change it back to its original settings...
Its a vodafone 845 (huawei U8120)..
A friend of mine tried to help and we found this recovery menu (Clockwork recovery v3) and he chose some format options (format boot, system and data) and now the phone is useless! It still doesn't recognize my SD card or my pc, I can get into this recovery menu again but cant seem to fix the problem!
Other than that all the phone does is show the initial hourglass forever...
I would be so gratefull if someone could help! Thank you in advance!

Well you wiped the phone, so there's nothing to boot into.
You need to put a rom on the root of the SD card (not in any folders). Make sure the rom is made for your device. Boot into recovery and flash the rom, you should have a working phone after that.
Thank you for you help!
Now the only problem that stands is that the phone doesn't mount my sd card... Its an 8gb kingston, maybe I should get one with less capacity? The previous owner used a 4gb card and she said she never had any trouble regarding that...
Although the phone specifications on the net say it can handle cards up to 16gb :S
Have you tried mounting the SD card in clockwork mod as the usb disk drive?
Its found under mounts/storage.

Ok guys, I've gotten as far as flashing the rom!!
Made huge progress in exchange for several hours of sleep xD
Now the only problem that stands is that when I choose the option "flash zip from sd card" I get this:
"E: No signature (242 files)
E: verification failed
Installation aborted"
And I'm lost again, yet soooo close to fixing my phone! :/

There should be an option somewhere to turn off signature verification. If you can find that option, toggle it off and try again.
You should try installing the original Firmware.Or Reinstall CM7
I got very similar problem. Have u tried to install different sd card. Maybe current one is broken like in my case?
Note: I do not have this device
See [GUIDE]All Huawei new&old phones-Install Stock Rom-Full Reset
Procedure:
1) Download stock ROM from HERE (im guessing you want Vodaphone UK)
2) Format your SD card to FAT32 (plug it into computer, right click on device, format, follow instructions)
3) Create the folder "dload" (without the quotes of course) on to the root (top level) of your SD card.
3) Extract the UPDATE.APP from the stock ROM and place it in "dload"
4) Power off your phone and put sd card in.
5) Power on by pressing POWER+RED_BUTTON+VOLUME_UP
If done correctly you will see a progress bar saying "UPDATING!"
Edit: this will reset the device to normal, however it will of course require a working SD Card. Try using a friends, try using your card in other devices (other phones, computers, etc).
To test SD Cards in your phone:
1) Insert Card
2) Boot into recovery
3) Go to Mounts & Storage menu
4) Plug device into computer
5) Choose "Mount sdcard over USB" (or similar)
6) If it shows up on the computer it is working, and you may as well use it to carry out the steps above
Note, if you are still checking for sdcard after resetting the phone, you will need to devise another method as the recovery will be replaced. For example use the storage menu in system settings, as this will show stats on the sdcard if it is readable.
My phone is working!
The problem with the SD card was that it was password protected, so I used another phone to disable the password, about the ROM, i just picked another one, I actually found it here on XDA! The celestial teapot, I really like it
Now all I want to know is if its possible to have multitouch on my phone?
And by the way, THANK YOU ALL for your help guys! You're awsome!

No problem, glad to help. Glad you got everything up and running too Multitouch is included in the kernel (at least on my device). If you can find a custom kernel for your phone, make sure it's compatible with your rom. I'm not familiar with your phone, so you'll need to do some checking on kernels. I'm not sure if multitouch is also a hardware limitation or not, so if you don't have multitouch at all it may not be possible. Kernels determine the number of touch points on my phone, if you don't have it at all then it may not be possible or there may be another mod for it.
If you can flash a custom kernel to achieve this, remember to do a nandroid backup first. Always do a backup when flashing anything. If they start to take up too much space, delete the old ones and just keep the most recent. Also remember to only wipe dalvik and cache when flashing a kernel.
Again, since I'm not familiar with your phone you'll need to do some research on these things first. The best thing you can do is read, read, and read some more. If you get stuck again, the good people here will always be able to help you out.
So, My little cousin is bummed out because his tablet doesnt have enough internal storage
to download a game he really wants.... I felt bad for him and decided to see if there was a way
to swap internal and external storage. well ... I found one, basically I rooted it and swapped out
the internal and external by txt editor in system files. Of course it wasnt that easy and now it
wont boot past the hisense smart screen. I tried to recover and reset to no avail. Does anyone
have any advice on reversing it ive been looking for hours .
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:
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"

Hi guyz, newbiw here, feel free to move this post if posted in the wrong place...
A few months ago, I bought a cheap generic "chinese" phone (only identification of it is "Model 6x" and some IMEI numbers). I has android 5.1, supposed to have like 3gb of Ram but had only 1.5gb, the seller did that on purpose, so I got a refund. So, having a free phone, I want to use it...
This phone has a "3-slots" slots, so micro-SD card, and 2 SIM card can be used, but there were no indication on how to put them in. On my first trial, I had to open up the phone to get my sd card back since it got stuck behind the holder. And then I found out the upper slots were for SIM cards (put them back to back) and the bottom one for micro-sd cards (contacts up or down?).
I tried to "boost" the RAM with an SD card as I read on a tutorial I can't find anymore. When I put the SD card in, and selected an option to use it as RAM, I must have put the card in the wrong slot or something, because it just went black and wouldn't do anything. I just left it in the box for a few months after that, and stumbled upon it a few days ago.
I am able to get in recovery mode, I wiped all data (user and cache) multiple times, rebooted, ect. I tried to plug it to my computer, it can't find it. It doesn't charge anymore either. The only good thing it did since I found it, is to find my SD card (after a few trials of putting it in the right way) in recovery mode.
Is there anything to do with that, or should I forget about it?
Thanks a lot!
