[Q] Stuck booting after attempting to format through TWRP - Galaxy Tab 4 Q&A, Help & Troubleshooting

Hi, I tried to format my device through the settings, and it rebooted into TWRP, I clicked format and it couldn't mount cache, so I formatted data only, now it can't mount storage. I've already tried flashing stock rom/recovery and it didn't do anything except replace TWRP.

I think I may have corrupted /data, but I am unsure.

Nevermind, got it working. Had to CHMOD 755

error mounting /data- brick? LOL

I tried reflashing a sense 3.0 2.3.3 rom because of some minor issues. Now I may have nuked my /data partition. first it wouldn't format so I pulled battery numerous times. and Mounted it through mounts and storage menu, then I hit format, and it formatted, so I hit mount again and flashed the rom. and when I restarted the phone after splash screen the phone restarted and went into recovery
Tried everything including mounting /data again and it keeps saying error mounting /data. am I screwed?
I have .2007 eng bootloader btw. shoud I try the pd15img?

I don't think you need to do that. You could do a fastboot erase, then go back into recovery and wipe data to reformat it /data, effectively starting from nothing.

Now I am getting mount /cache errors. aww man I think my phone is done....
edit: used the pd15img and I am back on stock :| s= off but I have the stock bootloader wtf.... how do I get my eng bootloader back?
this is how I fixed it:
I was on eng bootloader, but then I got reverted back to the stock bootloader.
This is how I encountered the problem. first of all I was having issues with raffy's fusion 3.0 rom, so I decided to reflash it, but it wouldn't flash or format /data, then I mounted it to through mounts and storage on the latest cwm 3.0.2.4 and hit format.
After that I tried reflashing his rom, it flashed but, after splashscreen I was redirected to my recovery instead. that's when I freaked because when I tried mounting data it said error cannot mount /data. so I fired up adb and did fastboot erase system -w and it erased it including cache.
then I popped up into recovery and BOOM started having cache mount errors experienced by a lot of people lately.
I thought I was SOL, but nope I downloaded the pd15img from http://www.megaupload.com/?d=V4NAODYZ
and put it on the root of my sd card and it worked....
so if anyone of you dudes are having similar problems try that ^

[Q] Tab won't boot. Clean ROM install doesn't help.

My tab froze and when I rebooted it, I get a black screen right after the AOKP logo. It just sits there forever. I can boot recovery.
My story is below, but I think my question is: How can I format the partitions, because I think /data is corrupt?
Story:
I can boot recovery, and I wiped everything, then tried adb pushing a rom to the /sdcard. That's when things got weird...
adb push failed, so I rebooted and noticed that /data wasn't mounted. (/sdcard is just a symlink to /data/media)
I mounted /data from recovery and tried to push the ROM file again. This time I got some I/O errors on the push. I also noticed that in an adb shell, the /data partition would sometimes unmount by itself, and threw disk errors when copying files around. All other partitions seem to work fine.
So I deleted everything in /data/media, formatted /data, and tried again. This time I could adb push the ROM. I installed the ROM, but I still get the same freeze after AOKP logo.

I would say you need to ODIN your TAB:
Use this:

[Q] [LG P700] Recovery Can't Mount /data

I've had a few problems installing ROMs recently; boot loops, errors etc. And then when I try to restore my back-up, having wiped everything - /system, /data, /cache, /(int)sd_card, it reports a failure to restore the /data. But when I restart my phone, it's still how I left it: apps, phonebook, messages are still there and still work. I can read and write to the /data partition with ES or Xplore.
It first occurred using CWM but it did the same thing with TWRP, as well. TWRP reports 'failed to mount data', CWM, in Mounts & Storage, says "unmount /data" but nothing happens when I click on it. It just flashes and stays on 'unmount' option.
Backup data from both recoveries is fine. It's the right size and if I copy it to my PC and unpack it, everything is there so recovery has no problem reading the /data partition. Just writing to it. Or formatting it.
Any clues as to what's causing this would be greatly appreciated.
I'm running V20E Android 4.1.2 by szymel.

Unable to mount /system in S4 I9505 - jfltexx

I flashed the root, then a twrp 3.0.2.0 recovery with odin and than went to recovery to make wipes. Had an issue with formatting cache (it was never ending process, more than 20 minutes) I lost my patience and removec the battery, came to twrp recovery again, enabled -rf fix in settings. Wiped everything and then came to install, chose the ROM and proceeded - then an error jumped, that the system was not mounted.
I tried almost everything, but system wont mount with twrp.
Is my only option to get back to official stock?
Did you try TWRP 2.8.7?

TWRP cannot wipe data cannot unencrypt

So I finally unbricked and booted the stock rom. Now im trying to reroot the thing.
When I go to format/unencrypt in TWRP I get ERROR 255 -t 0 /dev/block/mmcblk0p54
Is my data partition permanently corrupted? I know that partition exists inside /data.
I've already tried to manually format /data, repairing it, changing it from f2fs to ext4 and back. All failed.
I'm have a similar problem. I cannot mount anything thru twrp. System, data, cache, can't do a wipe all fail. I've tried changing file system the back but it fails. I was able to mount my sdcard and start the recovery but.... its. Been "working" for and hour with no process increase. I'm wondering if I can force a fix partition thru adb sideload. Or... how can I decrypt it. Also the internal storage registers as 0 out of 0, same as /data
