So one fine day my TF101G runs out of juice and shuts down. I did the usual, plug in power cable, wait for a while before powering on.
However this time the TF101G is stuck on the loading screen.
I'm on No-Name CM10.1 4.2.2 by josteink with CrossBreeder.
I also have TWRP installed, so I booted up with TWRP and tried to see what can be done. I noticed that there was an error message saying unable to mount /data regardless of what i try to do.
I supposed that would be the root of my failure to boot into the OS itself?
If so, what can I do to recover back into 4.2.2 without losing data?
Many TIA!
ok it appears that I'm unable to mount internal storage also.
I can enter TWRP but I cant do anything because i cant mount internal storage and /data

I know nothing about the G model but at that point I'd say you have to give up on whatever data was on there. Just start over, reflash a new rom. If it doesn't work, go back to stock then reflash.

Thanks Lethe, but I tried flashing CM10.1 but it failed due to unable to mount /data and also internal storage.
So I tried to flash stock firmware, but it failed also. Now I do not have TWRP/any recovery nor can I boot into CM10.1
I supposed the only way is through ADB.
But i'm not too sure how to go about doing it.
ok managed to get this working.
thankfully i still managed to boot into TWRP, and flash stock ICS firmware.
It didn't really went well because of unable to mount /data and internal storage.
But somewhere the flash in TWRP managed to take place and the tablet went to do some sorting out by itself and viola! it managed to boot into stock ICS.
run PERI and got everything up and running again. at the expense of losing all data but at least i dont have to get a new tablet
p/s: i look through the forums and it appears that the TF101 have a thing of building itself back up after a soft-brick

I have had my Nexus S 4g rooted for sometime and have flashed many roms, so I'm not a complete nooby... but for some reason I'm stumped right now.
I woke up this morning to my phone in the TWRP recovery thing and I just tried to restart my phone but it wouldn't boot up so I figured I would just restore to a previous ROM and all of my backups were just gone. This is the error I have: error opening /sdcard/TWRP/BACKUPS/randomcharacters
But that was way at the bottom, above it I see all these notifications saying that nothing is mounting... so I go and wipe all my stuff to try to re-install the ROM I already had because it had been working very nice and it was just gone. Couldn't find it at all so I figure ok... let's just mount it and put the ROM on my phone... but when I try that my computer tells me that I need to insert a disk into the removable disc.
So right now I really have no clue what to do and I can't use the one click stock since I can't get to my phone to turn on USB debugging.
Any help?
Sorry if this has been answered elsewhere but I was unable to find anything similar.
And I have tried unrooting using this site:
nexusshacks. com/nexus-s-4g-hacks/how-to-unroot-nexus-s-4g/
However, it doesn't work after "fastboot flash system system.img"
And when I go look at the log thing in TWRP I get this:
*Verifying filesystems...
*Verifying partition sizes...
E: Unable to mount /system
(x20 with different things!)
E:failed to mount /sdcard (No such file or directory)
Gah! Have no idea how this happened!!

Can you go into fastboot? I would try to fastboot flash recovery, flash CWM and start from there. If it still wouldn't work i would presume that either your NAND went bad or that somehow the partitions got screwed... I do remember something similar happening to me on my wife's SGS and the solution was a Odin flash of a stock ROM to restore the partitions.

I can go into fastboot! That is the mode I'm in.
I am currently trying to unroot my device using the unroot guide from nexusshacks. com but I get a forever hang time when it is writing my system.
So I just flashed CWM but I am no sure what to do from here! I tried mounting sd card and usb but neither worked. However, I did see an option to format my sd card. Should I do that directly from CWM? And in the advanced menu I see an option to partition my sd card.
At this point I just want to have my phone back in working condition.
You can try to format the SD card, but i think it won't work... If it doesn't work try to search for Odin and the files to restore to stock ROM, maybe it can fix the partitions... The SD card partition option in CWM i never used, so i'm not sure what it does in this case.
So I tried the Odin and I'm still stuck in the writing system stage... I have no idea what to do at this point.

Seems your NAND reach its end. There's allot of topics regarding that problem with the Nexus S and every single one of them ended up with the OP sending the phone to Samsung or getting a new phone...
I tried to install drumlock app and my phone restarted and went into the recovery. I can't mount the sd card either to flash the rom again. I dont have anything backed up. I am really lost and need someone's guidance.
I had the same issue one time what I did is I mounted the phone as a USB drive (don't know if it works with CWM, if not just flash TWRP recovery) and formated the SD card (when I mounted it Windows asked to format the SD card; Format in FAT32!). As you can imagine all data from the SD will be lost but your SD card is mounted again and you should be able to boot again. If booting still doesn't work try putting a ROM on the SD via mount as USB drive function and try to flash it. It should work.
worked but another problem happened :[

Thanks for that advice. Everything worked. I formatted the cd card and it is now seen in TWRP where I installed the viper one s rom. BUT! Now my phone just keeps on restarting - it shows the htc logo with a red banner under it and just restarts and does it all over again. I can get into boorloader mode If i get lucky pressing it before it restarts, yet the bootloader wont let me get into recovery. I am going to try other methods I guess but I am wondering if there is a way just to use RUU and restore it to stock?

You must've done something to your recovery when you formatted your sdcard. Try flashing TWRP again. You can easily bring your device back to stock by running the RUU. Info can be found around the forum.
Relock bootloader and run a official HTC RUU (warning: itll update hboot).
what worked but now its stuck

I tried that method and flashed utb rom and when i restarted it its stuck on the loading screen...so i tried the different viper one s rom and nothing either. After i locked it i tried the RUU but it gives me the error 150 ...Im on the right track I know...its probably something minor that I keep on overlooking.
gives me error 150

I also tried this method but it brings up the error 150. Could this be the recovery that is causing it ?
So you can't even get into recovery even if you flash it over fastboot?

I've been running CM10 nightlies on my Asus TF101 (B60) for several months and haven't really had any problems until last night. It was running fine and then I got a random reboot. Something must have went bad because during the reboot process it stalled on the CM10 boot animation (not a boot loop). I can get into CWM recovery just fine, however, I cannot mount either /data or /sdcard. During the CWM restore it runs for a little while and finally spits out an error that it can't format /data. It will mount /system just fine and I can wipe/factory reset successfully. I can even reinstall the latest ROM I have on the external sdcard but it still will not boot.
Without being able to mount the /data and /sdcard partitions directly in CWM, is there any way I can run anything like chkdisk, fsck, or badblocks on it? I've got both Windows and Gentoo Linux at my disposal and I'm not at all shy with the command line.

Had a lot of problems but not this one.. Anyways I think starting from scratch with easyflasher would be the best solution to make it functionnal again. Most of the problems I had have been solved by returning stock and reflashing a rom.
I haven't been able to get it to boot into APX mode yet. I saw it once but I didn't have the drivers installed. Since then I haven't been able to get it to go into APX mode again. Have tried several times.
After digging around on my laptop for a while, I finally figured out the drivers issue and was able to get into APX mode. This got me far enough to allow the tablet to boot using the stock Asus 4.0.2 ROM. I lost everything in /sdcard but I didn't have anything terribly important in there that wasn't being synced with Dropsync. After quite a bit of trouble, my own misunderstanding, I got EOS4 #89 installed and loaded as I've read that it's really stable/solid. I'll go back to try CM10 again after it stabilizes. Let the long recovery/configuration process begin...
When you say you can't get it to boot into apex does your screen turn off at least? Because if it is turning off the screen you are in APX mode, you might just needs new cable sadly. Same thing happened to me a while ago.

Wow this thing sucks! I'm really appreciating my Samsung with Odin right now! So, I have years of experience rooting and flashing Samsung phones with minimal adb experience. My buddy from work asks me if I can try to fix his shield tab that he F'd up trying to flash a rom on. Come to find out he never unlocked the bootloader or flashed a recovery or rooted the dang thing, just tried to flash the rom over stock like a numbskull. We thought it was dead forever because the only thing that would mount or connect in adb was the side load through the stock recovery. 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 even though it says "success" at the top after flashing. 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, I'm not familiar with any of the roms for it, and I'm not sure what prerequisites there may be for some of them....
Thanks for the help!

I had the same Problem with the partitions you discribed, have tried wipe them, change the file format and change it back?
I flashed a lot of Roms from the external SD Card and it worked every time.
I think you should go with Bliss Rom. ( Just try Lollipop and Marshmallow)

I can't wipe them because they won't mount. It's as if the partitions were erased completely. Not like the partitions were wiped, but like they don't exist at all anymore...
What do you mean by changing the file format? Format of what?

TWRP, wipe ,Advanced wipe
If that doesn't work just try installing a rom, boot it
If that doesn't work try this
Tried all recovery options and tried flashing bliss 6.2 with no luck. It says that it flashes successfully but also shows some errors about not being able to mount the system and data partitions. Then when I try to reboot it gets stuck at the nvidia logo (this is the closest that I've gotten to booting a rom). I can provide pictures if you want. I'm going to try the steps that you linked to as soon as the files download.
soo... i have a fully functional working samsung s7 rooted with the latest magisk and twrp recovery. after all the installation of apps and the root itself, i hopped into twrp recovery just to see if it was also working - turns out it's not reading any partition; leaving me with 0mb internal storage or unable to mount. i would also try rebooting but as soon as i enter "recovery" on twrp, it would automatically boot itself. i've tried researching for the problem but i don't think my research is good enough. i've looked out for multiple solutions, but i couldn't trust any. just wondering if any professionals on xda are able to fix this flaw. thanks!
tldr? working rooted s7, twrp recovery 0mb, automatically rebooting itself, couldn't find solution.
update: it's all gucci, i've managed to figure it out.
Have you tried the patched twrp version? There is a link in google camera port thread. I havent tried but that could work.

not a professional but coincidentally this happened to me today while rooting and installing twrp on my s7 sm-g930L 8.0, i installed twrp 1st and was just using a supersu.zip to root it, booted straight into twrp after flashing and had the same problem you have and couldnt install the zip as it wasnt showing up and also saying 0mb, i couldnt even send the zip to it from my computer either until i pressed format in the wipe menu next to advanced wipe button , it was in a bootloop so i hit format cause i was just gonna reinstall stock firmware but i noticed all the correct mb's appeared in system data etc and i could copy/paste n install the zip, flashed it rebooted and it all works, rooted and twrp on official fw 8.0, you might have to reinstall apps and stuff after but hopefully this helps, goodluck

INSTRUCTIONS BELOW WILL DESTROY ALL DATA ON PHONE GET BACKUPS IF YOU CAN'T IM NOT RESPONSIBLE
Get rid of encryption if you can then try
If you can't get rid of encryption or it didn't work then
Goto wipe and press format data
Type yes and press the tick at bottom left
Then once you see success or error messages go back to wipe
Swipe it to wipe internal memory
After success or error message shows you are most likely to be able to see and mount to internal storage.

Try using superman rom and use option called disable encryption that might work,
If you just wanna root then install magisk because it works with encryption
