[Solved] E:Unable to mount '/data' - Galaxy S III Q&A, Help & Troubleshooting

Hi.
I have strange issue, i was listening to music from my phone when it turned off, i thinked that the battery discharged so charged it and tried to boot up but then i get an error "Encryption was unsuccesful" and it only allows me to format phone. When i click it Turn off my phone and boot it in recovery mode (TWRP) and gets some "E:Unable to mount'/data'" and "E:Unable to mount storage" and reboot to ROM with the same error.
If i manually go to recovery i get few "E:Unable to mount '/data'".
What can i do now? Any solution to it? I readed that if i change recovery i will be able to format data, but my pc don't recognise my phone while it's in download mode (in recovery pc see it). Please help me fast
I was using Temasek Cyanogen mod 13 v3.2

I suppose you had your microsd card configured as internal storage. Something gone wrong and probably card got damaged. Try to remove card before entering recovery.

[Q] ROM Change now stuck on dualcore screen

I just switched to the Neutrino v2.2. Tried GT first then the EE. both are not going past the dualcore boot screen. I formatted my SD card before installing the rom. Not sure what i need to do to fix this. I can still get into recovery also but IDK how im going to put another rom on the sd card to try another one any suggestions?
This is a known issue with Neutrino at the moment. All you need to do is when it gets to the Boot screen just pull the battery and boot again, should work after that.

tried that 2x will try again..
Also, I noticed you said you put it on your sd card. I think you need to install it from the internal storage. Just boot into recovery and go to "Mount storage" and select to mount the internal storage and plug into your computer. Should be able to move files then.

you can move files w/o being able to get into the rom?? btw i tryed battery pull and still stuck at the boot screen :-/
I can see my sd card but my "g" drive is not avail..
Yes. Which recovery are you using? When you boot into recovery there should be "- mounts and storage", select it and at the bottom there should be "mount USB storage"

yup seen it and did it. I see my SD card in mycomputer but the G drive wich is my internal is not accessable
That's weird because "G" usually means External for me. Anyways, try selecting "mount emmc" in the same menu

actually mounted all of them so i knew i got the right 1 lol maybe that is the problem is the emmc folder..... is there a way i can "reflash" ext 4 or 3? i still have the emmc but if im not mistakin thats what the ext 3 or 4 creates.
That's just how CWM reads the file structure. If you can access it then it will work when flashing by selecting "install zip from internal storage".... I think. It's been a while since I have had to use it that way. But if you can access the internal storage then try putting the ROM zip there and retry flashing from internal

Thats the problem. I cant access the internal i just can access the sd card where I already put the zip file :-?
Well, you can put another ROM zip there that can be flashed from external. Also, make sure to perform the wipes necessary, either through fastboot or recovery. Hope you get it worked out.

could the problem lie with formatting the EMMC?
Possibly, at this point you're probably looking at a full wipe anyways so it shouldn't hurt anything.

I appreciate all your help bro
full wipe as in fact reset/delete cache and dalvik if so i do that each and every time I switch roms
Yeah, that's what I meant. Although, some people recommend doing the full "fastboot erase [partition]" wipes if you are going from a Blur based ROM to a CM7 based ROM, and vice versa.
boot into fastboot
fastboot erase boot
fastboot erase system
fastboot erase userdata
fastboot erase cache
fastboot erase webtop
fastboot erase preinstall
fastboot reboot
NOTE: when using this method you should already have the ROM zip on your phone and when you give the "reboot" command be prepared to boot directly into recovery (by holding Vol down after pressing "Enter") as this method erases the system.

[Q] Flashing ROM - Locating the ROM

I'm embarrassed to ask such a stupid question, but I've been digging around for hours and couldn't find an answer. Using TWRP, I was attempting to flash MeanROM. I placed the ROM in my Dropbox and downloaded it to my phone using the default browser. Booted into recovery and began to follow the steps. I created a backup, did my wipes, etc. So when I was finally ready to flash, I went into Install and have no idea where the ROM was saved. I thought it would be easy enough to find so I didn't bother checking where it saved before hand. I also couldn't find where my Backup saved so I couldn't even restore from there.
Could you please help me find my ROM or backup?
Switch mount points, perhaps the Rom is on external and not internal

I don't have an external SD card installed. I imagine that the ROM is in the default saving location for the browser, I just don't know how to navigate there. And I have no idea what the default saving location is for TWRP backups.
Downloads from the stock browser goes to my external sd card in the downloads folder. There's also a downloads folder on my internal card.

So I did a system wipe and it looks like that's where I went wrong. The directions said to wipe everything but I guess I got carried away as it looks like it cleared everything off. The only thing under the sdcard folder is a TWRP folder. But when I press Install and then go into /sdcard/TWRP, there's nothing in there. Shouldn't the back up I created be in there?
Please tell me I didn't brick my phone my doing the system wipe.

You didnt brick, you just need to put a rom on the card and flash. If boot fails, you will need to flash kernel through fastboot

I don't have a BACKUPS folder under TWRP. Did the system wipe delete that too?

When I tried mounting my phone to my computer from TWRP, it shows up as a drive on my computer, but when I try to click on it, I get the following message:
The Disk in drive F is not formatted.
Do you want to format now?
Is it safe to go ahead and format and will that erase all that's left on my phone?

Great, I'll give that a shot when I get home. One last question, which parts should I mount to format? System, data, or cahce?
you only need to select mount and then mount as storage, everything else can be wiped in recovery

and what rom did you restore? this is probably related to android 4.2.2 which moves your sdcard content to /sdcard/0 and when you return to android 4.1 this is not recognized anymore. i think it was in CM 10.1, there's some guide about going back to 4.1, you can try this but i don't know if it helps.
In worst case you maybe have to format you /data partition, but then all your personal data and sdcard content is lost.

had this problem once too, but i was going back to android 4.1 so i don't understand what messed up your /sdcard folder...
what should definately work is completely wiping your phone (all partitions including formatting /data again) and then do a fresh install of your rom using adb sideload. make sure you have the right kernel installed then.
maybe there's another solution, but i did not find any when i had this problem...

[SOLVED] i9300 stopped booting, how to save data? (CWM Recovery is working)

Very well, I have an international S3 (i9300) with the SlimBean 4.3 build 2 installed. It was working flawlessly, no bugs.
10 minutes after I put it in my pocket yesterday, I picked it up and it was stuck on the boot up screen, and it was quite hot. I tried rebooting it multiple times and waiting for a while, nothing happened. I have ClockworkMod Recovery 6.0.3.6 installed and working, so I tried wiping cache and dalvik cache and booting up, without sucess. It's stuck on the boot up screen and it gets a little bit hot after a while.
My question is, how do I backup my internal SD card data? Every single time I've wiped the device I used to move the pictures to my PC and made TitaniumBackup backups to the external SD card beforehand, so I could change ROMs and get all the stuff back. Now it stopped working, how should I proceed? I have important pictures and data in some apps...
tl;dr i9300 stopped booting out of nowhere, CWM Recovery is working, how do I save my camera photos and all data from apps?
Thanks in advance!
EDIT: Solved this by saving my data to the external SD card with AROMA File Manager, nothing lost!
Easiest solution is format system partition and reflash the exact rom you already have, unless the data partition is corrupt this should enable your phone to boot again.
Failing that you'll need to investigate if ADB pull will work in recovery/download mode.

Just tried formatting system and flashing the same ROM, it is still not booting
What can I possibly do to save my pictures? I'll look into ADB pull, is there anything else?
Flash philz recovery with odin, transfer data using aroma file manager, or custom backup, or usb mount internal sd.

I was googling and I had found about AROMA File Manager 10 minutes ago, but if didn't, I would because of this post. Thank you so much!
I was so damn worried about losing my stuff... I copied everything to the external SD card and now I can erase everything from the device and change ROMs safely. :good:

How to fix "E:Unable to mount internal storage"

Hi There,
I am having some serious problem with my galaxy S3 i9300 device.
When ever i try to start my phone it gets stuck on the first brand logo. Doesn't even go to the boot screen. Fortunately TWRP recovery is working. When i tried to format the data it says "E: unable to mount internal storage".
Tried to google on this but couldn't find any solid solution.
Can you please help me out here.
Regards,
Vaibhav Nagariya
@Vckydada: go to TWRP ..Mount: are system and data mounted?
Try another recovery and if that doesn't work flash a stock rom and start over.
I wish I stole my HTC M9.

Nope. Nothing is mounted. Nor data, system neither i am able to mount external SD card.
@Vckydada: as @shivadow said, go back to firmware. After flash with Odin factory reset. If this doesn't help, you've to repartition.
