Corrupted /data partition? TWRP 2.6.3

So I wanted to install a new ROM to my SM-P600. I had a CryogenMod ROM installed and wanted to go to Hyperdrive. I reboot to recovery and do the Factory Reset in TWRP. Afterward I go install the Hyperdrive ROM. However I notice that i'm getting the message that TWRP is "unable to mount /data" in the logs. The installation of Hyperdrive seems fine but I never boots.
How do I go about repairing the /data partition? I have adb and odin installed and working.
One thing I tried was going in to adb shell but I get this error when I try "could not load library "libc.so" needed by /sbin/sh". :crying:
Thank you for your help.

have you had any luck with your corrupt /data partition? i spent a couple weeks it seemed on my /efs corruption & it just needed to be remounted. i had to use CWM/PHILZ for adb commands. i know TWRP can do it but i had better luck with cwm + i was able to backup my /efs with cwm. if you are still stuck give me a shout
good luck

What is your process?

e: partition problem and boot loop issue. How do I fix it?

Hello. I have a kindle fire HD 8.9 32gb that I'm trying to fix for a friend. When I received it the tablet would boot to a screen that gives you the option to reboot or to try to reset to factory default. Neither option resolves the issue. I downloaded a bunch of programs and followed recovery guides and nothing works.
I can get it into fastboot and I got it to say it was flashing a new recovery, bootloader, and rom image, but when they were done, it now boots to scrolling text stating that it has an issue with the e: partition. Something similar to it can't access that partition. I don't see any mention of partitions in any recovery guides or software.
I got TWRP loaded onto it. I think I could get 2.7 loaded. The newest version wouldn't load. I can load the factory image, but still get that it can't write to the e: partition. Any ideas? Thanks!

bump. Still looking for help with this. Thanks.

Are you using the -i 0x1949 parameter in your fastboot commands? fastboot needs that parameter to know that it's looking for an Amazon device to flash to. Try flashing TWRP 3.0.0 from this thread, and choose the latest TWRP build - it should work, as it did for me. Also, the E: in that statement indicates an obvious error, not a nonexistent e: partition.

Twrp bootloop

Hello,
i just unlocked bootloader and installed twrp and it all went fine..
until i wanted to fully wipe my device, i did this via twrp.
after 20Minuts, nothing happend, the bar was still white and gray (not even a little bit blue)
and it kept stuck on ''twrp formatting data using make_ext4fs function''.
i knew this wasn't a good idea, but i decided to turn off my phone,
and now, everytime when i turn it on on the normal way it just redirrects me to TeamWin in a bootloop.
even if i want to go to recovery mode i keep stuck in that bootloop, so there is nothing i can do right now, i only can stick at Fastboot Mode but nothing else,
Is there any way to fix this problem?
Using ASUS ZENFONE 2 551ML

I hope you did a backup of your system before? Otherwise just download the latest full image:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.174-user.zip
place it on your internal sdcard (via adb push) and then flash it normally with TWRP. Please note that the procedure can take up to 30 minutes, where the formatting is the procedure taking the longest time...

but i cant use twrp on my phone because its stuck in bootloop, or what do you mean? (english not my main language)
please give me some proper step by step instructions, i would really apreciate that!
thanks anyway your awesome!

Man, I misread your post, sorry...I thought you could boot only into twrp
If you still have fastboot, why not flashing twrp 2.8.x.x?
Code:
Fastboot flash recovery nameofrecovery.img
Fastboot reboot recovery
Otherwise you could flash stock system with this guide: http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
It's a lot to read

wow, that is something really helpfull, there is still hope to revive my phone
i'll let you know how it turnt out xd
thanks alot!!

i fixed recovery mode, so thats already one step further. Oefff @TheSSJ thanks for the help.
But now i get some other problems, when i try to wipe my phone i get the error like ''unable to mount /data'' and ''unable to wipe dalvik''
and all other kinds of these errors, i get the same problem when i was installing rom. isn't there anything or a way to fully wipe all this **** so i can install a fresh rom.

i flashed custom rom and this is error log i get. its all full written down.

Seems you don't have a WW image installed, do you have a CN Software? Then you need another Software of course

what do you mean with ww & cn software?
sorry but im new in this.. but im really interested so can you please explain a little bit?
how can i get this other software! thanks!!!

Where did you buy your Phone? what does the packaging state? WW, CN, TW, etc? These 2 letters must be written in uppercase somewhere, then we will know which software to flash, there is a check where your phone's software is compared to the zip you are trying to flash:
assert failed: getprop ("ro.build.asus.sku") == ''WW''
Which TWRP did you flash?

ohhh yes, i do have CN software Probably, as it is buyed from china.
Where can i find this other type software?
thanks!

I think flashing will still fail though...but pls try first,maybe it'll work

i tryed it, i get the same error :/

Update: i changed from CN to WW.
Because of this i reflashed to twrp 3.0 and it works properly and now wiping shows no problem anymore.
I also got the WW ota zip but dont know how to install that.
Anyway, i tryed to install xaosp rom (even if my ota is still CN)
And it showed no problems at all!
BUT when i tryed to startup my phone it sticks with the asus logo and wont go any further, not a bootloop, it just sticks at the asus logo.
We are Always getting more and more steps further into fixing my phone, thanks for that @TheSSJ were almost there ?

You could try flashing cm13 first and then xosp:
First wipe data/cache
Then flash cm13
Boot up and hope that it works
Reboot to recovery
Wipe data/cache
Flash xosp and maybe a kernel that fits (FlareM?)
Boot to system again

sorry for the kinda late answer, but yes i followed your instructions, and it works completely, after cm13 i also immediately installed gapps.

thanks again your great!

TWRP Can't Mount /System - OP3 Bricks When Trying to Flash New ROM??

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc.
Also it seems TWRP can't mount /system, in TWRP under "mount", system is unchecked, I checked it and tried again but found that whenever I rebooted the phone or attempted to flash a new ROM, it would always uncheck itself and flashing the ROM would fail, however strangely flashing the same version of RR was always successful. Is this why the flashing keeps failing and does anyone know what the problem could be?
Thanks!

Go into your bootloader and format system, cache, and userdata (This will wipe EVERYTHING so be sure to backup). Then latest official flash stock rom and reboot. This should fix it. If this helped hit thanks!

Bootloader? There is no option in the bootloader to delete everything as far as I can see, do you mean in recovery? And if I wipe everything off the phone, how do I get the stock ROM onto the phone to flash it? When you say wipe userdata do you mean wipe internal storage or am I misunderstanding and you're telling me to wipe the usual dalvik, cache and data as you would for a normal clean flash?

bronderb said:
No, go into fastboot and plug into pc. Open cmd and type "fastboot format userdata" "fastboot format cache" "fastboot format system"

Okay, thanks, and then what? Do I flash TWRP then push the stock ROM to the phone and flash that? And exactly how do I do that?

You just go into twrp (no need to reflash) then adb sideload oxygen os

Thank you, I am now running OOS, hopefully everything else will go smoothly now, planning to go back to FOS again
I didn't even have to use the fastboot commands to format, just sideloading the OOS file wiped everything anyway

Turns out the issue isn't actually fixed, "system" still appears unchecked in TWRP. Could the fact that I didn't actually format everything first have made a difference, given everything was wiped in the process anyway?
Looks like I'm going to be living the sideloading life...
Edit: Sideloading freedom OS failed, ended up having to restore from my TWRP backup. I don't know what I'm going to do, my main reason for using custom ROMs is installing a black theme, and OOS doesn't support Layers or Substratum fully so I can't stay on that

Is the thing that says "mount system as read-only" enabled in the mounts menu? /System isn't ever mounted when TWRP starts, you have to manually mount it, but as long as the updater-script tells /system to mount, it will. However, if that option to make it read-only is enabled, then nothing will ever write to /system. Last resort is deleting the .twrps file from /sdcard/TWRP folder to remove current TWRP preferences and then when you boot into TWRP, that first screen has the swiper to allow modifications, and you'll swipe that

It isn't set to read only, I have tried updating and resetting TWRP but nothing has helped, in fact it's got worse, I managed to sideload OOS but my attempted install of FOS failed so I tried to restore from a backup and that also failed, something which didn't happen back when I was on RR.

Which version of TWRP are you running? The official 3.1.0-0 is good for OOS and OOS based ROMs only. Try eng.stk's version.

Use the latest eng-stk twrp.
https://forum.xda-developers.com/devdb/project/?id=15934#downloads
In recovery go to Wipe > Format data (this will wipe ALL in youre phone).
It's youre Data in F2FS? If yes you must change it to ext4, in recovery Wipe > Change file system. Reboot recovery. Check if it's changed.
Reboot to Bootloader (Fastboot). From PC reflash recovery.
Now copy Oos rom to the phone memory. Flash rom. Reflash recovery (the rom will overwrite the recovery). Reboot to recovery to see if it works. If not do it again.
I sugest to NOT restore old data. This way you'll have all new in youre phone.

Help! I attempted to do this and the process failed, I didn't manage to wipe data because "/data could not be mounted as device or resource is busy"
Edit: Device now has nothing but TWRP and fastboot, no OS, no ADB, no data, no internal storage

If you can reflash twrp from PC. If not reflash recovery from twrp recovery : Instal > Image > Select Recovery (you must have TWRP.img in youre phone memory )

I managed to get hold of a few factory images and attempted to flash system.img through fastboot, resulting error was
"target reported max download size of 536,870,912 bytes" (system image is 3080 MB)
"invalid sparse file format at header magi"

I reflashed the modified TWRP successfully. The second suggestion wouldn't have worked, given my phone has no internal storage

You can't see internal storage because of the recovery does not work write.
If you have a working recovery you can do all you want.

The recovery was working at this point, the issue turned out to be the data partition, system was formatted to ext4 but I didn't realise data was in f2fs which caused the problem in the first place. I formatted to ext4 and everything worked, I was able to install paranoid android and everything worked...
...until I flashed the wrong firmware and now I've hard bricked it! I'm going to try the hard brick toolkit
Edit: After 12 hours of being an unresponsive brick, the phone suddenly booted, system doesn't work but it has recovery. Unfortunately I seem to be back to square one, if I try to flash something it appears to succeed but then the phone doesn't boot up into system

So I am now back to the original issue of system not mounting, in terminal if I type "mount /system" I get following error:
"mounting /dev/block/sde20 on /system failed: Device or resource is busy"
Anyone know how to solve this?

I formatted everything, reflashed recovery and tried to flash OOS, got following error:
Code:
[FONT="Courier New"]"This package is for OnePlus3 devices, this is a oneplus3t" (it isn't)
"Updater process ended with ERROR: 7
Error installing zip file /sdcard/OOS3.2.6.zip" [/FONT]

Issue was "solved" by flashing PA, GApps and the correct firmware
Hopefully that's the end of all this drama, thanks to everyone for their suggestions

Hi, I'm pretty new at rooting and I seem to have a similar error. I'm getting the "can't mount /system" error in TWRP. I am able to boot into OOS 4.1.3 and run the nandroid backup but, I keep getting the same error and am unable to select "system" when choosing the mount option in TWRP.
Do I need to have all partitions in f2fs? My system partition is in ext4. Is this what solved your issue?
It seems my phone is functional even with the error active but, I've been trying to get systemless SuperSU and MagiskHide working and I think that's what is preventing me from doing so.

Hello. Need help is exactly what I need right now. Basically, I just tried flashing Oxygen OS from LineageOS, as I was just getting a little annoyed about how the updates were getting stupid and apps kept crashing. However, when I did this, it got stuck on just a sec when I was setting up. I then tore through the internet looking for how to wipe /data and /data/media with twrp command line. I found out about fastboot erase userdata. I used that. However, it wasn't just the casual wiping of the data where everything goes except the critical files. I mean every single little god damn thing got removed. I tried pulling /data and it said 0 files pulled. I was not happy. I managed to flash the rom but the phone won't boot. the worst part, I tried mounting /data on twrp and it said failed to mount data, invalid argument. So that was that. I then formatted to the original using the twrp format, (needed sighted help for that...) And it succeeded. Now however, I try mounting and it says no such device. 1, how can I mount data? And 2, how can I get a data partition that actually works with setting up and even the booting up of my phone. Yes, it won't boot.
Please help me, you don't believe how annoying it is to have a virtually useless phone.

PS, I was using stock bootloader and twrp recovery. Also, please give the answer of fixing in a command line method, I'm blind so getting sighted help would be rather annoying.

Not being rude, but do you really think no verity is going to help? I mean it usually doesn't fix stuff. Besides, thanks but it's not that it is encrypted, I can flash things if I know their directery, it's just that data can't be mounted. But thanks, I'll try flashing no verity and see what happens.

It won't mount data for many reasons but just installing stock recovery and installing OOS would fix everything.
