So just wanted to share this in the event anyone else runs into the problem. I was running CWM 2.5 and CM7 RC2 just fine for a while now and I decided to clean my SD card yesterday since I have tons of empty folders from prior app/rom installs. After deleting some folders, my SD card would not be read by the phone. I rebooted and it sent it into a bootloop. Tried to format SD card in recovery and the settings menu, no avail. Tried to partition in adb to correct the issue and /DATA would not mount for the life of me. I could get it to mount via adb, but not in recovery. Any time I tried to factory reset or format DATA, it would say it cant mount the partition.
Anyway, I tried the latest version of CWM (3.8) and it managed to format each partition without any issues. I could then install CM7 without any issues and it booted right up.
So if anyone is experiencing SD card issues when altering the filesystem in any way, try upgrading the recovery image. It would have saved me a good number of hours troubleshooting, but hey at least I learned adb better lol
I am having the same exact problem, bootloop with no way to access card. How did you get CWM updated?

I've been flashing the nightly build on my phone. The last time my phone was working was build 9. I than flashed build 12 and my phone got stuck on MT4G screen. I went ahead and did another full wipe but same result. Now I tried to flash build 9 and I still get same result. In a panic, I formated everything in advanced option and did another flash. Still nothing. I than followed this post in doing a wipe:
remove SD, power down device, SD in card reader, and delete all android created data (android_system; android; dcim->.thumbnails; tmp; data)
put sd back in phone.
boot into recovery
format boot
format system
{back to main menu} - factory reset
then mounts/storage, mount /system, mount /data
install .zip from SD card -> choose (CM-NIGHTLY-X)
then mounts/storage, remount /system (and /data if its not mounted)
install .zip from SD card -> choose (GAPPS)
reboot
win
So now my phone just gets stuck at the MT4G load screen. I can get into clockwork fine and flash but it just no longer will boot. Please help.
if you can boot into clockwork i dont think your bricked....try pushing the 2.x version to your phone and flash a 2.2 rom just to get to a working state.
then try again ?
I literally was going to have a heart attack. I was able to boot into the Nightly build. I guess theres something wrong with my sd card. I figured I try my 16gb card out of HD2 and it worked like a charm. Thanks for responding, I appreciate it.
Theres definitely something wrong with my 32gb Sandisk card. I formatted it with SDformatter to see if I can get it flash my phone and boot properly. Well, back to being stuck at MT4G load screen. The card works fine except for this problem. Now I just formatted 20gbs of music for nothing. FML!
haha no problem, try using HP USb storage format tool
I've done a bit of searching for my answer, however, am not able to find the answer.
I am having a problem running a restore in AD Recovery in the Magldr (v1.13).
Let me explain the situation:
I wasn't able to get App2SDPro to carry over apps to my SD card. I was informed it was because it was that I did not have an EXT2 or EXT3 partition on my SD.
I did that and then my SD was erased, but luckily I make regular backups of my SD card.
So I put all the information back on my SD card. I then realized that my ROM was erased as well.
So I tried running the backup I made from the recovery and got the error mentioned in the title.
I then tried to reload a ROM that I have on my SD at all times and then tried to do an advanced restore of the data and system and cache while leaving the boot but nothing works..
Am I destined to start from scratch, lol? (I had 140 apps installed)(and I'll be using a different form of backup next time, lol)
i have the same problem . while i was recovering from nand backup i have this notification 'Nand Kernel Open Failed'
Just flash again the kernel of your rom or the rom without wipe
you have to flash your rom om the kernel again and hopefully the problem will be solved
CLIO94 sorry i just see your reply
Hey guys,
I recently encrypted my phone for my work e-mails (the Exchange server required it). I made a complete Nandroid backup and also entire Titanium backup before encrypting, just in case something went wrong. But the encryption went beautifully.
However, I've noticed that I cannot mount /sdcard or flash anything from recovery. I can't update my Franco kernel or CM nightlies... It's a bit annoying because I want to keep flashing! lol.
My phone asks for my password everytime I reboot (in order to decrypt sdmount and mount the ROM), so I'm assuming this is the reason I can't mount it in CWM recovery.
Anyone know of a bypass or fix for this?
I don't really feel like restoring nandroid backup or doing a factory reset everytime I want to flash a new nightly, it just doesn't make any sense (besides I haven't even tried to see if I can restore from nandroid or factory resetting, they might not even work because it can't mount /sdcard?...)
I've searched around the forums for some complex solutions such as using ADB or Odin but I'm not interested in that.
Thank you!

Ok guys so basically restoring from nandroid did not work because of the sdcard mount error.
I did a factory reset, erased all data and format system. But I couldn't format sdcard or even user data as it didn't have access... Basically the phone got bricked from then on and I had to completely restore back to stock bootloader/recovery/stock rom with adb/fastboot. Instructions are found here:
http://forums.androidcentral.com/nex...e-restore.html
Hopefully this will come to use to someone else. I've heard that TWRP does not have this sdcard mount problem with encryption as does CWM, so that's what I installed this second time around.
Why don't you just transfer the files regularly without entering recovery mode?
The recovery doesn't allow mounting to the PC. It just doesn't work.

I've never mounted to PC in recovery. My files are backed up on my computer and nandroid as well.
My issue here is that I can't regularly flash new nightlies (and thus mount internal /sdcard to do so) following the phone encryption.
Since my internal /sdcard path is encrypted with a password, CWM recovery can't bypass this and it gives me the error "cannot mount /sdcard".
bump?
Any help would be highly appreciated!
Is this a lacking feature in CWM Recovery? Have the developers looked in it? Or is there already a fix for this without doing an entire factory reset?
Daily bump.
Anyone there? (echo...)

If you want to recover the data from SD card, you do not use the SD card.
You can try to recover the data from the card with some specific software.
I will try to fin one I used before.
It will take few minutes... do not use the card.

Many thanks, this link helped me restoring my Nexus 4. I enabled "encrypted storage" and wanted to root the phone and almost bricked it.
It's also possible to flash the stock recovery with odin, then do a real factory data reset and be able to install a custom rom, after (or before) which you can reinstall a custom recovery.
Hello all,
I am currently running the latest snapshot of Cyanogenmod 11 (M12) on my GS4 and last month I used Flashify to install TWRP 2.8.4.0 over the default CWM 6.0.4.7 recovery that comes with CM11. I did a nandroid backup to my external 64 GB microSD card and it would say that the backup was successful, and I could see it within the file manager and on my PC using MTP.
However, whenever I reboot into the OS, the backup folder gets deleted. I have then tried to backup only the /system partition to my internal storage, since I do not have enough space on my internal storage for a full nandroid. This backup worked successfully as I can access the folder from the OS, however I would still like to a full backup on my SD card since it has enough space for a full nandroid
Here is what I tried:
1. While in TWRP, I copied the newly created backup folder over MTP to my computer. After I rebooted the phone, I shut it down and plugged the SD card into my computer and copied the backup back to my SD card. However, when I placed the SD card back into the phone and powered it on, it deleted the backup again.
2. I reflashed CWM (same version, but newly downloaded and flashed using Flashify) and attempted to do a full nandroid. I received an error saying that the /data partition could not be backed up. Interestingly, I deleted an old CWM backup on my SD card, and after I rebooted that old backup was still there.
3. I flashed TWRP 2.7.1.0 and 2.8.3.0, and still have the same issue.
The version of CWM that I had before I installed TWRP would backup without issues. I am not sure if this is an OS, hardware, or an SD card issue, though my guess would be that when booting into the OS, Android deletes any changes that were made to the SD card that were not made in the OS. I am not sure how to fix this issue and was hoping someone on this forum could help, and I have searched other forums for answers, but haven't found one as specific as this, and solutions for similar problems haven't worked.
The phone works fine otherwise, I'm just worried that with CM12 M releases coming around the corner that I won't be able to install it properly with these recovery issues.
Any help on this would be appreciated, and if there is a better XDA forum for me to ask this on please let me know.
I figured out the issue. Turns out my microSD card is faulty. Sandisk will send a replacement.
So I successfully Flashed TWRP on my Galaxy Tab A SMT580. Two issues I'm experiencing tho....
1.) TWRP is unable to mount my internal storage which shows as 0MB. Thus I obviously have no ROM I can boot into. It reads and mounts my SD card and the correct size shows up. Unfortunately I have nothing on my SD card and I can't get ADB Sideload to work.
2.) Which brings me to my next issue whenever I do attempt to boot it says failure to verify. Which is fixed by flashing that DM-Verity zip file. But I can't since it's not on my SD card and, ADB Sideload won't work.
Any thoughts on how to fix these two issues.
I feel stupid having forgotten to put the file on my SD Card prior to flashing TWRP

By default, the data partition on the T580 is encrypted. In order to install a custom ROM, you must first format that partition. Click wipe then format data, type in "yes" and when it finishes, reboot to recovery. Your internal storage should no longer show 0mb.
ok that worked, my internal storage is now mounted, but my SD Card is not. Now I just need to figure out how to get the custom ROM files and the DM Verity file onto my internal storage.
how can I just flash the tablet back to stock recovery and ROM
so I got everything working, I didn't need to flash a rom, it booted to the stock rom, ony issue that remains, is for some reason the WIFI will no longer turn on. When I tap on it in settings to turn it on, it just says its turning on, but never actually turns on. Just hangs there. I can't figure out what to do
anyone ? I really need to get this fixed...should I reflash the stock rom using ODIN, maybe a fresh install will fix it ?
Also, when I plug my tablet into the laptop, it says connected device cannot access data, and the tablet doesn't show up on the laptop, so I have no way to transfer files or anything. It does show up on ADB, I thought about trying to push the files that way, but not sure if thats possible, been a long time since I used ADB.
