hey guys and girls, hopefully you can help me out.
I'm using a t-mobile galaxy S, trying to flash a new rom after I rooted it. I followed the instructions, and I have CWM able to load. when I got into select the install from the SD card, I'm able to select the file (trying bionix frost), it tries to load it, but then comes back telling me 'Can't mount /sdcard' and any subsquent attempts to even browse for the install zip give me the same error. I can boot the phone into the rooted stock image, access anything on the SD card there fine, copy files to it, etc, but CWM will not install the ROM's or keep the /sdcard mounted.
anyone here run into this issue? I'm using CwM Voodoo lagfix Recovery 3.0.2.8x
It's been awhile since I flashed that ROM...
Did you change the mounts manually? Does the OP say to change mounts? Back then we had to change the mounts ourselves in CWM to UMMU.
I'm at work and just sending a quick reply..check the OP to see what your mounts should be
to clarify a bit, this isn't just on a specific ROM, this is for ANY rom I try, after I access any ZIP file through CWM, it unmounts the SD Card and won't let me get back to it unless I reboot, and the cycle repeats.
Ok. Sorry I can't help you with that. I'm still kinda new.
I'm sure you'll get the help you need soon especially with your last reply.
Good luck and sorry I couldn't be of help.
I'm backing up and will format my SD card to see if this is the problem, saw this fixed a couple of errors like this for other peeps.
So since I couldn't get CWM to install the rom, I used ODIN and flashed to gingerbread. that's installed and working (had it fail the first time, but the 2nd installed and was up inside 10 minutes)
My wife's Galaxy S3 suddenly decided it didn't want to boot past the Galaxy SIII logo (which includes the blue Cyanogen mascot at the bottom)
I was going to attempt to re-flash Cyanogenmod 10.2, but for some reason TWRP prompted me for a password upon going into recovery. Hitting Cancel here allows me into TWRP. I flashed the latest version on TWRP, and still I am prompted by that password.
I then found that I was unable to wipe Dalvik Cache, and then found that I'm unable to mount /data.
Well that's not good. I assume that I'll have to use Odin to go back to stock and re-partition? Any suggestions would be appreciated.
Sounds like your /data is encrypted. When you're prompted for a password, that's to decrypt the /data partition (it's probably the PIN she uses to unlock the phone). Hitting cancel simply leaves /data unencrypted and unmounted. If you hit mount within TWRP, you'll probably see a "Decrypt Data" button. Try using the PIN and see if that works.

Yes, I think you're right about the encryption. How does /data become encrypted? She doesn't recall encrypting it through settings, of course. Her usual pin doesn't work to allow access either. If I can't figure out the password to decrypt /data, what's next?
Within CM, the ability to encrypt /data is selected within settings. It will ask you to set a pin or passphrase, have more than 80% battery and will reset to encrypt (you'll see a green wireframe android icon and an encryption progress meter). This is all a conscious decision, so someone must have gone in there to set it, if that's the reason why it's asking for a password. You can set a different password for encryption, but you would have to do this from the command line, which doesn't sound likely here.
If encryption was interrupted, it's possible the drive isn't encrypted, but TWRP thinks it is (the key data is stored at the end of the partition). I'm paraphrasing, but if that bit is set, it will always think the partition is encrypted. The only way to wipe that is to completely wipe the /data partition, which you probably don't want to do unless you've got good backups (and nandroid will not backup /data/media, so be careful with that option).
Do you know if the phone had adb debugging enabled? You could try running logcat while it boots to see what the issue is. I had something similar happen to mine (hanging at the CM icon at boot) when I upped from the October CM10.2 nightlies to the M1 release and ended up using ODIN to return to stock - it's a good thing I had backups!
You can get a shell while in recovery to poke around. You can try mounting from the command line there (the /data partition will be listed in the /etc/recovery.fstab file).
If all else fails, and you have good backups, you could try wiping /data from within TWRP, but keep in mind that all pictures, texts, music, etc will go with it! I would only do this as a last, last resort.
I've seen several threads lately about issues with the partition layout in recent flashing (esp. with the MF1 update). I've reverted back to stock as a precaution, myself.

Hey Joe, I appreciate you taking the time to answer the questions. I did edit my earlier response while you were responding, but to go into slightly more detail, her phone was just sitting on the arm of the couch, when she realized that it was off (it had been on just prior to that). She assumed the battery had died, but when I charged it to 100% and tried to boot it, that's when we found out that it wouldn't boot.
Anyway, wiping data isn't an issue. I have all of her photos and videos backed up, and most of her important stuff is stored in Google Drive. Unfortunately, trying to wipe data actually throws an error. Can you wipe /data if you can't even mount it?
EDIT: When I try to format data in TWRP, I get errors saying "E: Failed to decrypt data", and then it stops at "Updating partition details..."
Possibly a coincidence, She was previously using CM10.2 nightlies and just recently went to the M1 release.
So if we can't mount or wipe /data from recovery, I assume the next step is to go back to stock with Odin? And if that's the case, can you point me in the right direction? I am downloading Official VRBMF1 4.1.2 right now. Do I need a PIT file or something to fix the partitions?
Thanks again
Hrm..
I'd say going back to stock with ODIN will definitely get things back on track. You might need a PIT file to re-partition the device. You'll want to make sure it's the PIT for your model of phone (Verizon 16GB GS3, for example). Google turned up this:
http://teamuscellular.com/Forum/topic/3882-pit-files-for-all-us-variants-of-sgsiii/
I'm the SCH-I535 16GB so I used that one.
One other caveat - be sure you're running ODIN from a real PC - I was using a Virtual Machine and that caused issues.

Well, I wish I could come back with more insightful information, but through a bunch of poking and prodding in recovery, I was able to eventually format /data without having to use Odin. Thanks for the link, though. I'm saving the PIT file (same as yours), because who knows when it'll be needed.
This is actually the second time this phone has been stuck at the Galaxy SIII logo screen (with Cid, before the boot animation) in the past couple weeks. Both times were with the Cyanogenmod 10.2 M1 release. I think I might try RC1 to see if it behaves any better, but if not, it's back to stock she goes. If my wife didn't find TouchWiz so hideous, I'd likely go skip trying RC1 and go straight to stock and wait patiently for the 4.3 OTA.
So i soft bricked my device while trying to install the latest 4.0.1 image. I tried hard wiping the device and wipe cache partion from Stock Recovery but didn't help, still wouldn't boot. I tried installing the image in Stock Recovery from Apply Update From External SD Card, but i got a few errors first "E:Failed to map file Operation aborted", i took a look at the file and it had about 1.67gb extra in "Userdata" i tried deleting that file and reinstalling from external sd card but then i got "E:footer is wrong" "E:signature verification failed" Operation Aborted.
Now i'm trying to install update from ADB (Surprisingly if i have the tab connected and im in Apply Update from ADB the tab is recognized in ADB
Code:
adb devices
serial # sideload and i have updated the drivers) But if i try to flash the recovery file 4.0.1 (provided from the developers site [cant post links]) "i just get waiting for device"
Anyone know how to get around this issue in ADB or properly install from external sd card without getting errors?
(Alternative read to my problem posted in the Nvidia Forums 98% sure i soft bricked my device [cant post links]
Did you ever find a fix? I'm having a similar problem.
Try to use fastboot restore everything.
I can't get it to connect to fastboot. When it loads the boot loader and I try to select fastboot protocol it fails.
Wow this thing sucks! I'm really appreciating my Samsung with Odin right now! So I finally got it to connect to fastboot (don't ask me how, I don't know) unlocked the bootloader and flashed twrp. Now it won't flash supersu in adb sideload so I put it on an SD card (which now magically mounts and works now) and flashed the zip in recovery but it says at the very end of the process while trying to update the partitions that it can't mount the data and system partitions so I'm not sure if I'm actually getting root or not and if so if it's permanent I have no way to tell. I think this is because they have been accidentally wiped. Do you think it is safe to try to flash a rom in recovery from external sd card? And if so which one? I have no idea which version bootloader, kernel, or os is or was on this device...
Update: I think I may start a new thread in the Q&A/Help section so that I can try to get a vast concensus. Thanks!

Yes flash a ROM in recovery.
Try Resurrection Remix. It'll resurrect your device
Just tried flashing bliss 6.2 and it won't get past the nvidia screen. It says it flashes successfully but I still get a bunch of "can't mount such and such partition" errors during the flash sequence. Not sure what to do, I can post pics if you guys want.
If you got/can get TWRP on there now, the advanced wipe menu will allow you to check /data for errors. As for /system, wipe it. If you get errors that e2fsck can't fix in your TWRP log, you'll have to put on your data recovery hat on. If it's that important to you, my advice is to adb pull the right file under /dev/block. You won't get a block device, you'll get an exact image of your data partition. Once it's fully pulled (it'll be 10 GB or more on a 16GB device), make a copy of it first thing, and use data recovery tools (testdisk, or if you really know what you're doing, debugfs). If you don't have anything valuable on /data (remember that any backups you took from recovery go in /data/media by default), just format that and be done with it.
Pray that there are no errors after you format everything, because that usually means your NAND is toast.
If your errors are hardware ones, you're royally screwed. Same thing happened to my Nexus 7 2013 model a year ago. Only way to use it is to flash a modified kernel that will use an attached USB drive exclusively as storage. If the NAND is toast inside the boot partiti,try replacing recovery, otherwise, you have to tether boot it (fastboot boot) every time you want to run it, unless you have the guts to try repartitioning the NAND (unlike on PCs, messing up there is an instabrick).
Since the Shield Tablet can use SD cards, you're better off. No USB drive needed.
Hi all.
I've been searching the net for hours for a solution to this issue, to no avail.
I have an Asus Slider SL101 that I wanted to upgrade to KatKiss so here's what I've done...
- Root successfully (1-click transformer root 1.1 from here: https://forum.xda-developers.com/showthread.php?t=1689193)
- Installed CWM Recovery (6.0.1.3) successfully (also using above)
- put all the relevant zips (katkiss, gapps, slider comp pack) on the sd card ready for flash
- booted into recovery...
Next I went to wipe data/factory reset... but it froze so I did a hard boot and tried again: same thing.
So I went to install the rom zip from sdcard and I get error message 'can't mount /sdcard/'
Also getting 'error mounting /data' and 'unknown volume for path [/sdcard/].
I can't get back to my original Android settings at all, I'm assuming it's all gone or something. Maybe the reset did work.
The big issue is I can't access the damn zip files on the sd card to install a rom.
I have these ADB tools (with adb and all these random executables and various files scattered about) but if I can't start Android then I can't use them can I?
It's a bit of a mess really. I'm thinking if I can just get the slider to mount the sd card then I can install the rom and I should be back in.
I'm not sure how to go back to stock recovery (whatever that means) so if you advise that I should 'flash' then I'm afraid I'm going to need some clear instruction.
Stupidly, I forgot to do a backup, which is probably half the reason I'm here, although that still doesn't account for the sdcard error...
Anyway, please help a moron out?

Ive got the same problem. CWM cant mount the sd card. Ive been searching for days, but all the links in any solution i did find are outdated. I did read somewhere that it means that the CWM version isnt compitable with the Sl101. I can't find any other/older versions then the Manager i downloaded from Playstore. I want to flash the Twrp Recovery and then the kisskat ROM, compability pack.. Gapps
.etc but i cant seem to get any of that done if CWM can't mount the damn sdcard. (Sorry i got a bit frustrated over this). Ive never rooted anything before so im new to this. Did anyone find a solution for this? Or has an link to some other version of CWM that is compitable to mount the sdcard? Thank you very much in advance)
Probably not what you wanna hear, but I didn't find a solution and had to throw my beloved slider away!
I wanted to update my rooted Android Nougat to Oreo and also go from SuperSU to Magisk. During that process I discovered that TWRP recovery couldn't mount my internal storage.
I quickly saw on a lot of sites that it's a well-known issue, and I solved it by converting from ext4 to ext2 and back again. Now my phone is running perfect. All apps are installed, data and settings are restored with Titanium and root with Magisk is working fine. But then I remembered about the issue with TWRP and booted into recovery - just to discover the problem is back again. I can't mount my internal storage. So I can't flash zip files, I can't do a backup etc.
When I search xda or the web in general, I can't figure out why the problem has occured again. Also I can't find out how to fix it without losing all my data. Can anybody answer these two questions? Why is this happening again and how do I permanently fix it? And can it be with all my data on my phone - because I'm not able to do a backup.

The problem occurs when you use a ROM which encrypts the software or the ROM your flashing has an encrypted kernal. The only way out is to flash a ROM which doesn't encrypt. It is a known problem with TWRP and we have to wait for the TWRP team to update TWRP to handle quota allocation.
It seems the problem is solved for me. I flashed the TWRP version from this link: https://forum.xda-developers.com/showpost.php?p=77296102&postcount=1243
First I tried from Odin but it didn't work. Then I installed the TWRP app from Google Play and flashed the other file, rebooted to recovery, and it seems to work. I can mount my internal storage, make a backup etc. So this is the solution for me.
I had also similar problem of internal storage 0mb and i was not be able to mount my data
so when i flash color recovery by nobody
It's gone because it's allready patch by him
I think it's issue of encrypt data so just flash this recovery from nobody post

Hey guys
wondering if somebody can assist me with my issue. I can mount the internal storage via twrp, and can copy files etc over to the internal storage on my pc. But when i go into file manager nothing appears. even though i indicate that it show me the internal storage. any ideas?

same problem, have you found solution ? please help me
TWRP sometimes can't mount the storage, the storage is encrypted, but don't worry. You can still flash your files and rewrite system partion. But in order to show the Storage, you have to use a different version of TWRP. Why am I saying this is mentioned following:
I installed the latest version of twrp, It didn't ask for any password patter to decrypt my storage. So , different XDA posts made me understand that , formatting everything, factory reset will decrypt my storage. And trust me, I have done it several time, several times my brother but it didn't decrypt my storage. I couldn't backup my ROM and without backing up my ROM, I didn't take the risk of flashing new ROM. I waited. This twrp couldn't even mount my system partion. So I seeked knowledge from different person. It took a lot of effort.
Then I learned that, I should change this version of TWRP. I changed to an older version and it didn't decrypt my internal storage after formatting, but it mounted my system partion. Since, it couldn't decrypt my internal storage, I couldn't take backup of my rom and save it to internal storage. so I inserted a pendrive in my phone, and saved the backup of my rom there.
Permanent Solution
Flashing DM Verity Force Encryption Disabler will decrypt your storage instantly. But in my case, it aroused another problem, None of the security measures of my phone worked afterwards. FOD, pin, password, pattern none of them worked. I don't know the reason but I don't suggest it with my little knowledge. but almost every rom flasher use them, so I thing I have to study about them to know how they work.
second and best option: start trying older version of TWRP, the good one will be the one to ask the password the recovery in the beginning. It will decrypt your internal storage.
I was brief here, if anyone doesn't understand these things, let me know, I will explain them step by step because I know the pain of being NEWB.
