Hello,
I had already a custom ROM on my phone (AOSP Extended). When I opened TWRP and wiped everything (including system, data and internal), TWRP couldn't install my ROM because of some error code 7 (but that's not the main problem here). When I opened fastboot on my phone, I installed twrp into my phone using fastboot. The TWRP did boot up just fine. But when I clicked "install" and selected the custom ROM, TWRP simply closes, reboots the phone and TWRP starts again asking me if I want to allow changes. I noticed that this isn't because of my custom ROM. I tried also other things such as Gapps and TWRP does the same thing.. I don't know how to fix this. Can you please help? Thank you!

Hi there,
Today I received my Xperia Tablet Z and sure enough, the first thing I did was flash a custom Rom
But my device wouldn't boot up anymore...
Basically I unlocked the bootloader via Sony's key, flashed a boot.img via fastboot and then flashed the Rom via the recovery.
All I got was a bootloop - regardless of which custom Rom I used (AOKP, Cyanogen stable, Cyanogen nightly, Cyanogen unofficial, ...)
I tried doing a factory reset but to no avail.
I manually checked for each delete / wipe option in the recovery, but the device simply would not boot further than the boot animation.
However, after some time I stumbled across a Rom that contained the TWRP recovery instead of CWM.
And this one asked me for a password when I booted.
"A password? What for?!"
Well, simply cancelling the request works.
But it seems that my whole problem had to do with that password request
As it turns out, the data partition was encrypted would not let me access it.
For some reason unknown to me, it was not wiped in CWM (some error popped up when trying to format /data).
TWRP allows for doing a format on this one ("full wipe" if my memory does not fool me) and voila - the tablet would boot!
So to sum it up:
After unlocking the tablet, there might still be an encrypted /data that can't be accessed by any custom Rom.
Wiping this /data solves the problem - and can be done via TWRP.
I just banged my head on that issue for 5 straight hours - downloading new custom roms, looking for similar bootloops, ...
Maybe this information will help someone

I usually just hit the thanks tab but feel I have to than you personally for this post. After hours of messing about I found this post, flashed the TWRP recovery, wiped data and was able to flash and boot my xperia..
Thank you for sharing this info..
For others searching you can get the twrp recovery in this rom http://forum.xda-developers.com/showthread.php?t=2383800
hey guys just looking for some help. ive been modding and flashing phones from 2014, but its always gone really smoothly, so my diagnostic ability is lacking.
it started with flashing twrp. my bootloader is unlocked, usb debugging on, device is showing in adb and fastboot, and i can flash twrp without any issues. hoowever when i go to boot twrp, only the stock recovery boots. i tried to flash twrp using the XiaoMiTool v2, but the same thing happened. i eventually got around this by just booting twrp instead of trying to flash it. so i got in, took a full back-up and started installing a custom rom.
the first one i tried was ParanoidAndroid Quartz. i wiped cache, dalvik and storage then transferred it to my phone, tried to flash and got "zip verification failed". so i turn off zip verification and tried again. it flashed perfectly with zero errors. however, when i reboot the phone it would only boot to stock recovery and not twrp (expected) or the new rom. i tried that a few times, then tried LineageOS, and MSM Xtended 10. all of them had the same issue, the flashed without a hitch, then wouldnt boot.
i also tried flashing a new fw-vendor and it just straight up failed. Then i decided to cut my losses and restore my twrp backup, and that came back with the error, "extractTarFork() process ended with error: 255"
Software before i began these attempts was completely stock, so i dont know what is going wrong, but as of now, my phone is bricked, i cant install a new rom or restore my back-up.
any help is appreciated guys. thanks
You can figure out this problem with
1 Copy backup folder to computer
2- Format Data - Yes , Wipe Everything
3- Install ROM that you have installed before and boot
4- Go to TWRP, format data yes reboot recovery
5- Paste backup folder to internal storage and restore
Hello
I was at RUI C07 stock firmware.
I've managed to unlock the bootloader and to install TWRP 3.4.0. Then I've tried to flash derpfest (android 10), LineageOS and RevengeOS.
All of them seems to have flashed successfully, but TWRP always warns that there is no OS installed when I try to reboot. When I do reboot, it tries to load something, fails and goes back to TWRP.
What is the problem? Should I try to flash vbmeta? Where can I find it? I'm completely lost.
Thanks in advance
I've just followed the "unbrick guide" and there was little developement...Now the phone boots to fastboot/bootloader by default. I can boot to recovery if I request it. But if I just turn on the system or if I request system, it stops at the bootloader.
What a roller coaster ride!
What seems to have worked for me was to flash yet another ROM (crDroid). But this time I made sure that I've formatted DATA, and then I've wiped vendor, system, caches, internal disk.
I may have forgotten to format the data partition before, which might have been the cause for so much trouble.
If you are reading this, don't forget to format the data partition before flashing a custom ROM, at east when coming from the stock rom.
Hello, I now have 8 days note 10 lite today I unlocked bootloader, installed TWRP via adb after that I installed lineage os and wiping data etc. After that I faced a bootloop and lineageos bootscreen doesnt go away after 15 minutes.
So I tried to reflash the rom again, but twrp isnt able to reinstall the rom. I then used miflash to get original rom again.
Started all over installed twrp, flashed lineage os after this install after reboot I get everytime back into TWRP and looked on my pc and all files suddenly are encrypted on my phone and cant get lineage os rom again on my phone..
So I used miflash again and decided to ask here first. Does anybody know if I maybe use a wrong TWRP or missed a step?
I really dont understand it, I tried it for a 3th time. Here is exactly what I did.
- installed TWRP through ADB (TWRP-3.4.0-0_Android11_Roms_AndroidHQ254)
- In TWRP put rom on my internal storage
- Wipe Dalvik, data and cache
- Install rom (TWRP-3.4.0-0_Android11_Roms_AndroidHQ254)
- data wipe (where I had to type yes to confirm)
- Reboot to system and then it doesnt do anything and goes back into TWRP where I cant do anything, and I have to flash original rom back through MiFlash.
I run now MIUI 12.0.2
Android 10
Try using orangefox recovery. And i think you have to wipe data before installing rom, not after it.

Thank you, I was able to do it with Orangefox.
Hi, I've recently repaired my mido with a new screen after a fall. After this I tried some custom roms. Initially I managed to install lineage 18.1. After I switched to dotOS. From this point on, the phone restarts a few seconds after the launcher appears. To fix this I used MiFlah to install latest MIUI, formatted data, wiped everything, tried TWRP and Orangefox, tried other custom roms with no changes. Now only stock MIUI11 works. Other custom roms (included lineage) gets the phone continuously rebooting. Could be an hardware problem? What am I doing wrong? It is the first time in ages I have problems flashing ROMS .-.
Thanks.

The vendor partition could have some code/ file that persists stock ui or system
and make sure your phone was rooted before flashing custom rom
and also via twrp flashing. from what Ive seen flash in twrp before flash custom rom( https://www.google.com/search?client=firefox-b-d&q=disable+encryption+treble ) then flash the "verity and encryption disabler ,theres another one to re enable encyption only " then flash custom rom
after flashing custom rom reboot poweroff(switch phone off via twrp)
reboot into twrp and flash whatever else you need
now reboot to system and your phone should work fine
Thanks, it worked!
I did:
Flash last miui with miflash
Flash recovery
Flash you suggested zip
Format data
Flash lineage 17.1 (android10)
WIpe system, data, cache, art cache
Flash any android 11 ROM

Holy **** how did you come up with this.
Either the zip with Magisk somehow fixed it or installing the android 10 rom somehow. Either way doesn't make sense

Didn't work for me,

i think somewhere in the process the persist partition gets damaged .

so if you have magisk you can use a zip file to chmod 744 or 644 (it may be "chmod root 744" )the /persist partiton and thatll mean only true root has access
so 7 is read write execute 6 is read and write 4 is read only 5 is read execute i forgot which number was execute only 1 maybe?
so play with the permissions or look in the root folder for boot.p or permissions.sh then you can modify in there the permissions, it can cause bootloop , so always keep an original copy or youll hae to reflash(DISCLAIMER)
so you can pull the file using adb+root / or a root explorer
Copy it to phone then edit then copy to SDCARD
reboot to twrp then use shell/terminal "chmod 777" the partition where the file is / or read write everything
then copy the file and overwrite the original
