I own a Galaxy Tab PRO 10.1" Wifi (SM-T520).
I have the stock ROM, rooted and with TWRP. And SDfix...
I have tried fat32 and ext4 on MicroSD, and without MicroSD. No difference.
I cannot boot any custom rom (Stuck at Samsung logo). Sometimes when I try to install a rom, it fails, or reboots TWRP.
I also encountered problem when trying to restore a nandroid. No DATA partition can be written to, restore fails. (after reboot recovery, its no problem to restore)
Angry Birds Epic does not work. It stops at "Loading Levels", and sometimes it fails to start, and says its not installed.
Spotify says that that it cannot be used because it has no storage.
I can access the partitions, but they are not writable. A reboot is getting the internal/external SD to be writabe again.
So, what is the problem with the partitions on TabPRO? or is it the Samsung android rom thats the problem?
Can it be fixed?

Try installing FolderMount from the PlayStore. It can detect and fix issues with your partitions. You just need to run it, then reboot. I seem to get issues writing to my data partition after I install TWRP, on my SM-P900. FolderMount fixed it quickly and easily.

FolderMount did find an error, and fixed it, but same result
And it "fixed" the same problem as the SDfix app did.
But, I still made some progress. I managed to install a custom rom without error, and fully booted.
Team Freeze Rom installed fine. The rom is just under 800Mb. So i thought maybe it was some faulty memory sector on my tab.
Then I tried to flash GigaWatts ROM, and it failed. Same with ProPlus Rom.
When restoring my last nandroid, it fails when writing DATA partition.
Then I tried to restore my first nandroid, from "stock" rom, and it restored just fine.
First nandroid was from internal SD, and latest was from external SD. Made me wondering, so switched yet again another MicroSD, took a nandroid to it, and tried to restore. It fails again at DATA.
Then I tried t install GigaWatts ROM from internal SD, instead of external. Works without error.
Sooo.... I can flash custom ROM`s from Internal Memory, and restore from Internal Memory
Not from external SD.
Still, I do get internal/external SD dropouts, and getting "no space left/no memory to install on", which can be "fixed" by a reboot.(Still, it should`t be like this, and are quite annoying.
But, still no luck on getting past the "Loading Levels" on AngryBirds Epic
Where is the root of the problems? Faulty device? Android ROM? TWRP making trouble?
Please guide me if any logs should be provided to find out where the problems is, if i`m not the only one with these problems.

You can try flashing a stock ROM via Odin, and start from scratch. Factory Reset, Reroot, install twrp, etc. If you still can't write to /data properly, you may need to find a .PIT file and repartition your internal memory using Odin.

I have had to reflash stock with Odin 4 times by now, and it has been the same pain every time.
I was hoping not to use re-partition, so I will wait and see if some new info will come by from other users, as I see there are more of the users that struggles with flashing custom rom. (Stuck at samsung logo, installation fails)
So, will hold off for a few days, and if no new info about partitions, rom flashing, low memory, sd cards not mounting correctly, etc, then I will try re-partition...
meanwile, I`ll investigate som more on my own, read overall the internet
Ok, so i have tried and failed, and learned something on the way
Ext SD is useless for flashing rom, nandroid, etc within TWRP. It does not mount partitions correctly.
If I make sure DATA partition is mounted in recovery, and only use Internal SD, everythin flashes, backups and restores just fine
(Mabye an issure with TWRP?)
SDfix, or FolderMount fixes write permissions to Ext SD in rom to use TitaniumBackup, games, downloads, etc.
Hopes this can help others in simular problems.
And thanks to all that have helped on the way

Hi all,
Let me start with the fact that I did something really stupid, I formated the storage in TWRP (version 2.8.0), instead of just wiping the dalvik, data and other. After that I installed the custom ROM, however the tablet would not boot, it stays at the boot animation. If I go to the TWRP, I see that the internatl storage is 0MB and it says it cannot mount \data and other files.
I tried installed other ROM as well but same thing.
Tablet is rooted.
Help me please to recover the tablet (P600)!!

Load the rom on an external sdcard, and flash from there. I usually wipe everything when flashing a new rom except for the external sd card. If that doesn't work, try booting into the odin download mode and reflash to stock firmware via ODIN. Then try flashing again.
Hi,
My LG G3 d855 has fried, the flash chip looks dead (unable to flash new system partition, when I try the dmesg from the recovery kernel shows error from the flash chip).
So now I'd like to know if it's possible to install everything on the SD card and boot from there. I already made a copy of all the partitions (I can still read from the flash), the /system partition is unusable but all the other ones look good.
Has anyone tried that ? Or does anyone have an idea where I could stick some boot arguments to make it work ?
I was running oos based nougat custom rom with blu spark recovery. Then flashed official ob1, didnt like it, wiped cache/data/system and reinstalled my old oos nougat rom (audax 4.7.6). Now i get the above mentioned message..
Things i tried:
- addionally wipe internal storage and media (installed rom via adb sideload then)
- reformat system/cache/date with ext4
I googled the error and for most people (threads werent particularly concerning the op5t however) it seems that just wiping data and reinstalling the rom did the trick. Not for me though..
What can i do now?
Solution: reformating the data partition with ext4 is not enough. I had to format to FAT and right after that again to ext4, reboot to system and boom, it worked!
PS: i wonder what data is on the internal storage partition that i deleted? I didnt have any data on the phone, i just wonder.. It isnt somehow crucial to the phone?!
I think the decryption key is somehow embedded into the internal storage as wiping /data does not delete the PIN/pattern. Might be a hidden partition or something similar that is not wiped when wiping /data as long as it is ext4.
Your data is gone. It failed to completely encrypt and now there's nothing that can be done. Format /data as ext4 and let it try encrypting again
I have the same problem exactly. Can you explain in steps you have installed then format or how?

I had the exact same problem. But it is an easy fix but does require wiping your internal storage.
So the save way of doing this would be:
1. Backup all your data by going to TWRP or your ROM if that still works. Plug in an USB cable and use MTP or the adb pull command to backup your data
2. Reflash OB1 with no root (like Magisk of SuperSU) if you have TWRP. This will cause you to have the stock recovery again. I also recommend to do a clean flash (Wiping system and data before flashing the rom).
3. Download the rollback build from Oneplus [HERE] and copy this to the internal storage.
4. Boot into the stock recovery flash the rollback build. THIS STEP WILL WIPE YOUR INTERNAL STORAGE.
5. Now you have OxygenOS 4.7.5. Download OxygenOS 4.7.6 Incremental Update [HERE]
6. Go back to the Stock recovery and flash the incremental 4.7.6 zip.
7. You have the latest version now. So boot to fastboot reflash TWRP and flash SuperSU or Magisk in TWRP to regain root
Guys I did a fail, i had OB3 installed, and I wanted to try RR so I wiped system and when I tried to install I have seen error 7 saying its for dumpling not for oenplus5t.
So I restored.... But instead restoring OB3 I have restored stock Nougat rom -.- I have even stock recovery now, what is the best way to fix it?
Can i change to FAT and stay and dont go back to ex4 again?
Hi i don't know if u r reading this but if you are please help me cause I'm so lost and confused over this since yesterday...
so 2 days ago my phone started lagging and hanging and freezing until i realized i have got this issue with data encryption
i have a rooted sony z2 with TWRP Custom recovery
first i didn't know it was with data encryption failure so i literally factory reset and installed all my apps and data again and again!!! after every time my phone started to lag !!
after one whole day of trying everything i finally realized its actually with the data encryption and i should change my ex4 to something else... so here again i wiped the phone and changed to ex3 and installed and all my data and apps all over again
but after a couple hours...same problem again.....
im literally so tired of not knowing what to do ! my head hurts so much due this ugh....
i havent changed to FAT from ex3 so im wondering if it will finally solve my problem permanently if i change to FAT ??
And if it did can i just keep it on FAT forever ?
Please guide me thanks ...!

Finally. Thank you so much!
Hi, I regularly flash new roms for our device to test them, so I'm using TWRP for a long time.
2 weeks ago I installed the stock oreo rom and the TWRP recovery via fastboot.
Yesterday I wanted to test ToxycOS so I tried to wipe everything. The log does not show any error but the system and internal memory are sill there. From the main page of TWRP, if I go to ''Install'' and then ''select storage'' it says that there are ~50000 Mb in the internal storage, and I still can see all the folders with the TWRP file manager.
I even tried to format data but the result is the same.
The device won't boot but the files are still there.
So now I can only dirty flash roms.
It never happened to me before, what can I do?
