My ZTE Awe (Virgin Mobile) soft bricked over the weekend. It spontaneously rebooted and got stuck at the green android logo. If I wait an hour, it finally coughs a generic error, then reboots. I have CWM recovery installed and am able to get into that, though it still takes an hour. It is also rooted.
I initially tried wiping cache, followed by dalvik cache, then wiping the factory data partition and factory reset. None were successful.
If I boot into CWM recovery I can get into it using ADB and have been able to determine that there are several bad blocks on the data partition (userdata) causing it not to mount. I have also tried to install TWRP and the AWEsome ROM (modified, rooted ROM for the ZTE Awe). TWRP seems to install, but it isn’t (tried rebooting to it – no dice). The install of the Awesome ROM bombs out with an error about set_perms on the data partition. I tried pushing them via SD card and sideload – same errors.
My next attempt was going to be to completely wipe the data partition using dd then use mke4fs to recreate the data filesystem (I figured the data there is lost anyway).
Unless someone has a better idea.
Depending on the flash organization, having bad blocks may be a completely fail for you.
If those bad blocks are located as a single cluster and you can re-partition your flash around it, then it may work. Otherwise, you are probably looking into replacing the phone to something else.
Yes I think the only way is try to repartition the data but if there are corrupted sectors you have to eliminate them. Be carefully because a non correct repartition can brick your device irreversibly!

Any ideas on how best to accomplish that effort? I've tried the factory reset from CWM recovery and it seems to pass, but doesn't. I also attempted to run 'recovery --wipe_data' from inside the adb shell. Nothing seems to work. Next, I was planning to try 'dd if=/dev/zero of=[partition]', then run 'mke4fs'.
What do you think?

Probably you don't have another chance, the system needs to repartition the data eliminating corrupted sectors...
Try this:
cat /proc/partitions

One day, about 2-3 weeks ago, on my way to home, I decided to install an other ROM (5.1.1 ivanchi -> CM9). Went straight into recovery (TWRP 2.8.5 or 6) and formatted everything except microsd, everything seemed to go as planned. Then proceeded to install the ROM; it gets stuck, can't get pass the booting screen even after 20-30 minutes. Force-Reboot into recovery and receive "unable to mount /data | /system | /cache error". Tried changing fs-type of /data /cache /system to any other type, no success.
Got back home, tried installing RUU. Got stuck at 39%. every. single. time. !! Tried an older RUU, same response.
Then tried even oem lock + flash recovery_signed.img + boot boot.img with fastboot and then RUU install. Then again with unlocked bootloader. Still no! But, I didn't tried lock + recovery signed + boot + S-On, because I am afraid not to be able to regain S-Off at this state.
Even tried a parted format, implying that one guy managed to make it work in the end. See topic here : link.
Tried doing guy's steps but after parted /dev/block/mmcblk0 I receive Error: Can't have overlapping partitions. Tried then parted /dev/block/mmcblk0p23 (userdata), it works, and if I try mkfs/rm on partition 1, it says it's in use (p23p1 ...).

I can format my /data /system /cache one at the time, after doing reboot recovery and that's only in CWM 6.0.1.2. But this CWM isn't able to install ROMs somehow, wether it gets stuck of just plain fails. So, if I want to install a ROM, after the format, I have to install 4Ext (latest) recovery and do it there. Install everything from recovery, boot, sign in for GApps etc etc and while trying to install apps from Google Play, after about 4 to 6 apps, it gives a black screen, leaving no option but remove battery and reboot. Do that and get stuck on bootsplash / bootscreen. Everytime!
If then I try formatting paritions using 4Ext most of the time it fails, making them unmountable again after all.
Tried everything mentioned running PG58IMG with firmware 3.33, Hboot 1.27.1100, worldwide english (.104.). Tried fashing rom.zip as the PG58IMG.zip from fastboot in rebootRUU (gets stuck at [RUU]WP,dzdata,0) and now even from sdCard (gets stuck at [6] USERDATA).
I dug furthermore into bricked Sensation, seeing a QHSUSB brickbug (thread). It is refeered to be a bootloader brickbug; problem which I am not facing right now. Eventho, followed OP's instruction my freshly installed Ubuntu 14.04 can't detect my HTC. Also did some of the YouTube instructions, connecting sdcard's plate with lower pin from the back (trolled?!) (video), yet nothing.
Out of disperation, asked hinxnz and rzr86, and both of you adviced me to try thread 1 or 2 (relying on sdCard as primary/sec partitions). Good advices but I don't consider this be the best solution for this problem; STILL HAVE HOPE MAKING INTERNAL SD TO WORK! :d
ASK ME ANYTHING REGARDING MY PROBLEM! Will post every bit of information you consider relevant.
PLEASE HELP!
u tried ruu, didnt work, tried firmware, didnt work. @rzr86 and @hinxnz gave u those guides coz its the only known way to fix/bypass that problem on xda. maybe there is another way but no one has found it yet. u could take ur phone to a repair shop, pay bout a hundred bucks, connect it to jtag and hope for the best, but that might not even flash partitions back.
personally i dont see how twrp is still allowed to be downloaded on xda in the sensation thread coz it keeps killing peoples phones. that jus my opinion tho.
Atm my phone is literally bricked, QHSUSB brick because of my stupidity... Maybe I will make it to work again; anyways...
For the partition problem, don't the HTC has some kind of .pit files like Samsung does? They should! Also, what if someone with a 'healthy' Pyramid does a dd of the /dev/block/mmcblk* for those with fk'd partitions to use ?
Hi, one more here with wrecked partitions by TWRP factory reset....
Trying to Ruu the Sensation, but RUU has been getting stuck in the process ... I'll edit if I success.
Thanks for all the info out htere!
Edit: no success, even tried at last to fix partitions (parted and fdisk) via ADB, device is now dead. So sad HTC or any ever gave the details for the partition table, a simple script might have solved this.
I'm just catching up on this one.
If I read this right,the information on the partitions was trashed by TWRP recovery?
There was a member that stated the HTC Desire used to be able to have it's partitions reconfigured,IIRC.
Perhaps this is the first step to achieving that with the Sensation?

Hi, i have a problem with my sensation.. When i tried to do factory reset from phone settings including SD card (i didnt needed anything from sd) before installing new rom, something went wrong. After that format my phone doesnt boot any more, it get stuck on rom logo. I still can enter bootloader and recovery (TWRP 2.8.6) but when i try to use factory reset (wipe) again in recovery it shows me this (i cant upload images so i took everything in text):

Sounds like good old "there goes your motherboard". I've had it happen last week or so.
you used wipe option from twrp
big mistake

pay attention to the last posts
As @Harakhti and @rzr86 said, you are in deep trouble, just like many of us. Unfortunately, no one knows a solution to this problem. It is an old phone and most Android tech "wizards" have upgraded to newer devices, so I am not so sure we will ever get one. People here try their best to come up with solutions (and are being helpful), but the diagnosis is always the same: eMMC blocks are corrupted, no data is allowed to be written on them. Possible fixes? Complete repartition, but we need to have detailed information about whole partition/block layout, and the right knowhow.
Check the thread @rzr86 has linked. There is a post by @Harakhti that provides some (very) technical information about a similar problem. It could be related to our Sensations, but this doesnt solve our issues unfortunately.
But you know whats the real problem? I am convinced that the TWRP pyramid .zip on their official website caused this problem to appear in the first place. 4EXT and ivanovichs recovieries seem to be safe. Amount of people who encountered this problem and soft-hardbricked their phones keeps on growing every day. And yet, this .zip is still on that website, so more and more people who are looking to mod their old smartphones are installing this buggy version. We, as a community on xda, should make sure that no more phones will be damaged by this glitchy piece of software.
Still, I am sorry for that. I am in the exact situation. My phone is being "repaired" by my fathers friend, but I am pretty much convinced that this phone is a lost cause. Unless a miracle happens. Sometimes they do. Most of the time not.

This is pretty summarizing and accurate, except I got bricked with Ivanich's TWRP R14 for CM13.
The issue, if it's what I assume to be, would be that the eMMC just burns itself out when given a secure erase command. This possibility is tough, since it's about almost impossible to find a replacement motherboard for this device (FYI, the price for the mainboard is around 50€ at the time of writing, which is a hella lot for a device that costs around €95 total in a retail store around here).
To be honest, I'm not keen on getting a new phone, so if I turn out to be wrong, then I'll be happy that I can keep it for a few more years. This device has proven that it's absolutely capable of running any and all Android versions as long as you have a decent SD card.
I srcewed up my data partition with @ivanich twrp on one of my two sennys.
Weired since I formatted partitions many times on one phone in twrp, but the first time I switched from 4ext to twrp on the other phone,
the partition was corrupted after 1st wipe.
I still use this phone as a daily driver with @hinxnz mod "All Data on SD-EXT" (here) using a fast class 10 card.
There's definately no remarkable performance difference between the 2 phones + now I have a larger data partition.

Funny thing is that secure erase has been disabled in kernel few years ago the same goes for discard and other dangerous things, also it has been disabled in userspace utils like mkfs.*
At the most cases it's ends up like this:

Hello ivanich,
I accidently formatted /data with the TWRP that is linked in your cm13 thread.
As i know now this will mess up the partitions for our Sensation as some other people have experienced as well.
I dont blame any one else than myself for not looking into TWRP enough, but maybe it is an good idea to warn people about using TWRP in your initial post.
When there is a recovery that is 'promoted' by a qualified person as you, people often think that everything fully works on this recovery. As happend to me.
So maybe just add a warning? If i manage to get my phone working somehow, i will make an instruction that can also be added.
Thank you for your work on our phone, i used your cm 12 for a long time and it was awesome.

Sometimes peoples bricked their phones with official twrp builds
Okay. You seem to be right, sorry.
I looked into my Download history:
I downloaded ~6 different versions from your google drive and 1 single version from twrp direct.
With my luck i bricked my phone the one time i had the wrong twrp installed... That makes it even annoying for me
Sorry to bother you,

Odd. Thanks for the heads-up. All I did was change between the CM12 and CM13 versions, so I'm not sure how I screwed it up (particularly, formatting got stuck in 2.8.7.0 R14 for CM13).
But I guess the suspicion's correct and I blew my MMC, right?

I'm not sure about that. Discarding device blocks: 4096/305852 - according to your log mkfs was completed succesfully but discard failed. Try to boot into recovery and play with mkfs and data partition, something like this:
make_ext4fs /dev/block/mmcblk0p23
or
mkfs.f2fs /dev/block/mmcblk0p23
Hey, @ivanich
Its good to see you here
Maybe those commands will help other people. They did nothing for me. unfortunately. I tried commands with mmcblk0p23, 22 and 24 (/data, /system, /cache), but it all said something in lines of "make ext4fs not found"
Either my ADB was not setup properly (weird because every other command i needed worked fine) or my partition table was broken beyond means of repair.

This guide was written for the Huawei y6 with a gpt partition table, mounts that use partition names not numbers and the userdata partition is the last one on disk however with a little adaption this should work for most gpt devices.
If you are unsure if your system uses partition names for the mount system look in /fstab."hardware" to see if your devices are labelled in the following manner. "/dev/block/bootdevice/by-name/system".
If the fstab file does not exist all is not lost look in your root directory at the .rc files for the command mounting system.
If you are unsure ask in the thread before doing anything. Better to ask than be stuck with a brick.
This guide covers modification to only system and userdata partitions but if you use great care the basics covered here will allow for modification to other partitions as long as you understand the risk and know that backups are your friend.
If you are unable to follow instructions and end up with a bricked device that is your own fault and attempts to blame me will be laughed at.
I obtained the attached parted binary from here
So you have flashed a custom ROM and without all the OEM bloatware you now have some unused free space in your system partition just sitting there gathering dust.
You are stuck with this space... Wrong.
You can repartition your device with a little paitence, time and work.
Read along if you are curious about how to get the space you deserve.
Prerequisites:
Free space (Duh).
The ability to follow instructions and to read ALL steps before you start so you know what your plan is.
An unlocked bootloader which you already have if you flashed a custom ROM.
A custom recovery (twrp preferred).
Parted binary (see attachment at the bottom of this post).
A computer with adb installed and working (there are many guides out there if you don't have it, Google is your friend).
A calculator (well I'm sure your computer has one but just so you know).
Some knowledge using terminal commands.
Risk of Bricking your device:
Low if you backup and can double check typing and calulations.
High if you can't do one of the above.
Because parted does not allow resizing of ext4 partitions you must delete partitions you want to change then recreate them.
All steps must be performed while in recovery because you are going to have to unmount any partition before you can change it.
Step 1:
Boot into recovery and make a backup. You MUST do this otherwise you will have nothing to restore.
Step 2:
Plug your device into your computer.
Copy the parted binary into your working directory on your PC.
Open your Command Prompt (Windows) or Terminal (Linux) and navigate to where adb is installed and you also put parted, or if you have adb in your PATH just go to where parted is.
Run
Code:
~ # adb devices
to ensure your device is present.
Run
Code:
~ # adb root
to get root priviliges.
Run
Code:
~ # adb push parted /sbin/parted
/sbin is in your devices PATH so you don't have to worry about typing /parted.
Run
Code:
~ # adb shell
Run
Code:
~ # chmod 755 /sbin/parted
If you get an error about a read only file system run
Code:
mount -o remount,rw /
then try again.
Step 3: Now you need to do some homework to find your sector size, sector count and how much free space you have available.
DO NOT shrink your filesystem to smaller than you need to operate. I always add at LEAST 50 mb to the used space however I recommend you think for the future, are you planning on restoring to stock?, are you planning on flashing OpenGAPPS?, are you planning on moving third party apps into the system?, are you planning on adding media or custom boot animations to the system?
So in the case below I would not make the partition any smaller than 800 MB.
Code:
~ # df
Filesystem Size Used Free Blksize
/system 1.2G 748.5M 441.8M 4096
/data 5.2G 3.5G 1.6G 4096
/cache 147.2M 4.7M 142.5M 4096
Now issue the following command to get your disks sector size in bytes remember to note this down.
Code:
~ # blockdev --getss /dev/block/mmcblk0
512
Time to use parted.
Issue the following commands to get some info on your current partitions.
"unit s" tells parted to show sectors instead of blocks, bytes etc.
Code:
~ # parted /dev/block/mmcblk0
(parted) unit s
(parted) print
Number Start End Size File system Name Flags
22 876562s 1191132s 314571s ext4 cache
23 1191133s 3990839s 2799707s ext4 system
24 3990840s 15269854s 11279015s ext4 userdata
Remember to not the partition number as you will need it later.
Remember to note your partition name with exact case, if you changed "system" to "System" you will have problems.
Also note the start sector of your system partition for the later steps.
Also note the end sector number for your userdata partition for the later steps.
Now get your calulator ready.
Some things to keep in mind here are that the number of sectors times sector size is the size of your partition in bytes and your starting sector must be 1 after the end of the previous partition.
So the following equation will give you the numbers you need.
Desired size in MB * 1024 * 1024 / Sector Size = Number of sectors
Starting sector + Number of sectors - 1 = Last Sector
If you want a 1.1 Gb partition, you have 512 byte sectors and the starting sector is 1191133 you would then use the following equation.
1100 * 1024 * 1024 / 512 = 2252800
1191133 + 2252800 - 1 = 3443932
Step 4:
Now using the info you have gathered you can change your partitions.
So I would issue the following commands to delete, create and name the system partition with the size I want.
Code:
(parted) rm 23
(parted) mkpart 23 ext4 1191133 3443932
(parted) name 23 system
Now to resize the data partition.
You need to start with the first available sector after the end of system and end with the last available sector noted earlier.
Code:
(parted) rm 24
(parted) mkpart 24 ext4 3443933 15269854
(parted) name 24 userdata
Now that your partitions are all done you can exit parted with the following.
Code:
(parted) quit
Step 5:
Now restore the backup you made earlier.
If you get an error restoring which usually only happens if you have altered partition numbers just reboot back into recovery and restore then so the kernel gets to update its own info.
Reboot.
Congratulations you now have repartitioned your device.
Don't forget to thank this post if you are grateful.
Is there anything diferent to do about moderm mmcblkop14(/firmware)? I want to reduce it to 100 mb but i noticed its blocksize it's different from the others (others =4096, firmware=16384). I saw in your pictures you reduce it, so i will try it to do that. I have a nandroid so i hope this try works.
OK, i should probably been the first idiot to bricked his phone by reading a tutorial.
I need some help. I was trying to make this extra space and i have a few problems during the process.
First of all, in my case i have a partition 23 called cust, exactly the same in size with the cache. So i started with the cache calculating and then the other 3( 23 cust, 24 system, 25 userdata). For that moment i already made my nandroid, buy for some stupid reason I saved to my pc.
My problems came when i began with step 4. When i tried to put the cache it told me that it can't do it because it was in use. So i twrp y put on mount and desmounted that partition and then i could keep going. Same thing happened with Data partition, i did the same.
Finally, i did it all the tutorial, just needed to restore as it said in step 5 because i didn't have it in my phone. So i tried with adb push but nothing and i couldn't mount again those partition with twrp. Then, in a desperate move, i tried to reflash my cm rom, so i did that. And later, it bootloop with te huawei logo and i can´t flash a rom o restore my nandroid. It doesn't read a sdcard.
And now, when i see the script in twrp (sorry i don't know how is the name, i talking about the center botton in twrp) it appears in red "unable to mont '/data', '/system', '/cache'.
I don't know what to do, really, i need a hand.

OK, i should probably been the first idiot to bricked his phone by reading a tutorial.
I need some help. I was trying to make this extra space and i have a few problems during the process.
First of all, in my case i have a partition 23 called cust, exactly the same in size with the cache. So i started with the cache calculating and then the other 3( 23 cust, 24 system, 25 userdata). For that moment i already made my nandroid, buy for some stupid reason I saved to my pc.
My problems came when i began with step 4. When i tried to put the cache it told me that it can't do it because it was in use. So i twrp y put on mount and desmounted that partition and then i could keep going. Same thing happened with Data partition, i did the same.
Finally, i did it all the tutorial, just needed to restore as it said in step 5 because i didn't have it in my phone. So i tried with adb push but nothing and i couldn't mount again those partition with twrp. Then, in a desperate move, i tried to reflash my cm rom, so i did that.

Ok this is difficult because of your wording but it sounds like data, system and cache no longer exist.
Is your device the y6?
Do you have adb access?
Did you finish recreating the partitions?
Did you manage to name them if so?
Are you able to use recovery?
If you have adb can use please issue the following code, if you don't have adb can you please use twrp, advanced, terminal command to issue it.
Code:
ls /dev/block/bootdevice/by-name/
and let me know if it shows your cache, userdata and system.

- Yes, my device is Y6 (SCL-L03).
- Seems that i don't have access to adb, because in cmd show me "offline" device.
-Yes, i fineshed with that, but couldn't do the restore of backup.
- I did all step 4.
- Yes, i'm using twrp.
I put the code with twrp... and here it says not found.
Any ideas? I hope you could help me.

Ok I suspect maybe the filesystems never got created.
Can you run
Code:
df
this will show you the currently mounted partitions free space.
Output will look something like this
Code:
Filesystem Size Used Free Blksize
/dev 442.6M 60.0K 442.5M 4096
/system 1.2G 948.5M 241.8M 4096
/data 5.2G 2.8G 2.4G 4096
/cache 147.2M 176.0K 147.0M 4096
/persist 3.9M 776.0K 3.1M 4096
/firmware 99.8M 46.8M 52.9M 2048
If you dont see data or cache they never got mounted at twrp start, system is not mounted by default.
Then if data is not listed try
Code:
mount -t ext4 /dev/block/bootdevice/by-name/userdata /data
Remember to have spaces between arguments.
Or try system by replacing "userdata" with "system" and "/data" with "/system"
If you get an error trying to mount please do the following referring to the attached screenshots.
In twrp, go to "wipe", "advanced wipe". Then select one of the partitions and select "repair or change filesystem".
This should give you info about the partition.
If you wish to reformat it select "change filesystem" then select "ext4" and swipe to confirm.
Now retry the mount command and hopefully it will succeed.
Do this for each partition then retry your backup/flash.
Hopefully this works, good luck.
Thanks for your help. At first i couldn't see cache or data partition. I did what you told me, and i made cache to appears with df command. System too. But i couldn't made the same with the userdata partition. I tried to repair but it didn't work.
Is there another way to remount that partition?
A question apart: what was that "cust" partiton i've got and you didn't in your images posted in cm12.1 post? Because i recalculated it too.

Hi,
Does twrp show the userdatas partition filesystem type? Like in my previous screenshot cache is shown as ext4.
If not can you try change filesystem instead of the repair option and choose ext4.
I removed my cust partition altogether as I had no use for it.

Can you please try using parted again with the guide to delete then recreate the partition making sure to specify the filesystem.

In twrp can you mount mtp or usb storage and copy it to sdcard then twrp filemanager to copy to sbin?
Ok, i tried with a sdcard, but i couldn't either. It didn't recognize my sdcard. And i don't have an otg's usb.
But in twrp's cmd showed "mtp enabled". Could this means that i have to mounted the sd partition? If that is a yes, could you please write me the code ?

Hi DestructoSphere, i finally resolve this. It was a lot simplier than you ever thought. I tried changing to ext2 my data partion, and then change it again to ext4 and that's how it works again.
Take a look into my partitions. But i still want to reduce to 100mb the modem partition.
Hello guys,
I run into a problem recently were my device won't boot. I tried a plethora of different solutions but nothing worked, I will have to factory reset to fix the issue.
My problem right now is that I can't access my files to make a backup. On my computer the device is connected and recognized but I can't access it's files. I also have TWRP and in TWRP Recovery it's unable to mount the Internal Storage and it shows up as 0MB. After a lot of research what seems to be the problem is that my files are encrypted, I don't know why this is (I guess for protection) but I didn't have any problems before. To my understanding if the phone is booted up you can access the files but if it can't boot then they stay encrypted. The encryption key should still be in my phone since I haven't formated it.
So how can I decrypt my data so that I can backup my files ? there must be a way for cases like this when something happens and the device can't boot, since the key is in the device it's self and I have the phone I should be able to, I also have access to every single account (google, xiaomi etc.) that is associated with this smartphone. If for security reasons that is not possible, would an authorized repair center be able to do it with proof of purchase and ownership ?
I am not 100% sure of my os version but it was 12.5.x.x, I have the unofficial twrp 3.5.0_10-beta. USB Debugging is enabled. Any other information you might need I can provide!
Thanks a lot everyone !
Your phone basically uses FBE ( File-Based Encryption ) to encrypt /data partition. When you boot phone into Recovery mode then the recovery.fstab file gets read by system
If you take a look into this file then you can notice that /data partition isn't encrypted ( it's only flagged encryptable and NOT fileencryption ).
TWRP will ask for lock screen credentials used for decrypting userdata partition. on FBE encryption the partition is mounted and even with no credentials provided one should at least see encrypted files.
In your case it's bit more complicated as that device uses FBE + metadata encryption. while in TWRP provide recovery.log to see what is going on. (share link to pastebin.com with expiration date 1 month)
Code:
adb pull /tmp/recovery.log
Note: there exist no relation between (FDE) encryptable= and (FBE) fileencryption= flags, these flags aren't interchangeable.

Hello guys,So my devices is stuck in a bootloop, I want to reflash the ROM but I need a backup first.Things I've tried to fix bootloop that didn't work:
Re-flashed the boot.img
Re-flashed the vbmeta.img
Wiping cache through TWRP Recovery
Things I've tried to back up my data:
Going into TWRP to make a backup it reads: "Internal Storage (0MB)", when I try to mount system or data I get "Unable to mount."
When I use the Mount->Decrypt Data option it asks me for a password, I tried every password I ever had on the phone and any "default" ones I found online and nothing worked.
I tried the adb pull command from my computer I get: "0 files pulled, 0 skipped." and nothing gets copied over.
So I don't know where to go from here, I have some things I have yet to try like:
Re-flashing ROM (dirty flash)
Re-flashing ROM update
Flash TWRP Update (if any)
But I don't know if they're going to to anything or just waste my time. Also I am not sure any of the 3 options will 100% keep my data.I am not too worried about apps and settings but more about Photos, Videos, PDFs, TXTs and Downloads.
Any ideas on what I should do ? Thanks a lot !
My device: Xiaomi Mi 10T Pro

No, that wasn't the cause of boot-loop. but next time you must not follow random guides without understanding what you're actually doing. yes, formatting userdata partition deletes all data. it's too late now...

I was under the impression that changing the system file could be done without deleting the data, that's what the guide said and there was no warning or message regarding loss of data inside TWRP (for example there are a lot of messages in the WIPE section) so I figured it could work... I was out of options... damn...
So I am screwed pretty much ?
wording matters.
changing the system file could be done without deleting the data.
changing the file system of the partition not. this is common sense, no warning required.
my explanation: you don't know what a file system actually is (but then you're not in the position of dealing with file systems anyway)
https://forum.xda-developers.com/t/...ed-to-unlock-bootloader.4531349/post-87917999
that said, if it's any consolation to you, encryption of userdata partition was already corrupted beforehand. on (plain) FBE encryption some users could repair ext4 file system with e2fsck. your device is formatted f2fs which isn't as easy to repair as ext4.
'Repair Partition' fsck.f2fs could have worked in case the f2fs file system have had (minor) issues.
But in your case most likely (if I got the recovery.log right) the early metadata encryption was broken (maybe metadata partition faulty) so there were no chance to decrypt block device anyway, which is prerequisite for mounting/decrypting or even just repairing (FBE encrypted) userdata partition.
So the chances to recover any files were very low to zero from the beginning.

Yeah I know, for real I don't know why I didn't realize. I've been changing file systems of USB Drives to use for softmoded consoles and I format them every time. Yet I didn't even realize I did the same here...
But yeah, since I didn't have much luck from the beginning I guess it just made it easier for me to delete my files...
Thanks for all the help and the explanations !

Hello and sorry for bothering you again.
I am currently trying to fix the bootloop, I formatted userdata back to f2fs but I noticed Cache is also on ext4 format, should I change that as well ?
Also on your original comment on how to fix bootloop you told me
aIecxs said:
factory reset device and format userdata back to f2fs from fastboot
Click to expand...
Click to collapse
But factory reset fails so I am changing the file system first before trying again.
I will also root my device again as soon as I have it up and running, will a factory reset be sufficient ? NO leftovers or anything ? Or should I go with "Format Data" or just wipe everything ?
And absolute last question, I am trying all this through TWRP Recovery. Will any of the above mentioned options (Factory Reset, Wipe Data, Format Data) delete TWRP as well ? As I said since I will root the phone again I would like to remove TWRP as well and do a clean install.
Thanks again !
Format Data is what I meant with factory reset. you can do it from TWRP. you haven't changed file system of cache therefore no need to change file system to f2fs.

Format Data is what I meant with factory reset. you can do it from TWRP. you haven't changed file system of cache therefore no need to change file system to f2fs.

Oh so Formatting Data keeps magisk ?
So there is no need for clean install of TWRP or Root ? I just update anything if needed and I am good to go ?
Edit:
After rebooting the device and trying to re-activate it with my Mi Account I can't connect to the internet. SIM Card is inserted, I was not asked for a pin and it shows no signal (there is definitely signal). Turning on wifi shows 0 available networks even tho there are plenty. Any idea why ?
you lose Magisk superuser but you won't lose root. just install apk from github again.
the other issue sounds like you lost baseband, probably due booting into wrong slot.
