Bootloop When Flashing AOSP Nougat Z6533 - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

I've unlocked bootloader, installed twrp, wiped, flashed and wiped dalvik/cache. Whether Resurrection or Lineage, roms hang on the boot animation. I've even tried flashing over the Rom with itself to no avail. Any ideas?
EDIT: Solved. Had to format internal then wipe then flash. Booted right up.

Stuck on boot loop after installing official Oxygen OS Pie Community build

I was running a custom ROM (Skydragon) earlier. I simply booted into TWRP, did the basic wipe then flashed the official zip file. Then after booting, its stuck on the boot animation for more than 20 minutes now. Any ideas how to resolve this?
I too faced the same issue. formating the data partition and flashing community beta build booted successfully for me. before you do this, completely back your phone contents to pc
You must flash with TWRP 3.2.3.0 or older!
i had the same issue. formated data had 3.3.0 twrp but still bootloop so i used unbrick tool to put my phone back to stock and then updated to last build though stock recovery and then unlocked bootloader, installed twrp, magisk and done.

Have I bricked my device?

I unlocked the bootloader, then proceeded to flash orange fox recovery. After I flashed that, i then flashed it once more. then I wiped dalvik cache data vendor and firmware. then flashed the dm verity zip then the chinese vendor and firmware then then rom itself (syberia os), then gapps. I'm not bootlooping, and I can still access the recovery, but I am stuck at the boot animation. Is my device bricked? What can I do to solve this issue?
[Sorry I only just noticed that I posted this in the wrong section]
FORMAT DATA.
then install the AOSP rom
Bricked applies to when it won't switch on at all.
reflash with mi flash

Stuck at MI Logo...

Hello all,
so i have an strange issue here. after installing magisk canary yesterday evening, i ended up in a bootloop.
so i stayed pretty cool and went to twrp, used magisk uninstaller and thought hmm okay ****, still not booting, not even shows the boot animation now.
stuck at the MI logo, flicks one time, and then stuck again.
so trying to reflash magisk then with 20.4, but nothing changed.
i ended up doing a full wipe, downloading the latest v12 vendor global and reflashed the rom.
booted up all fine. set it all up again, did a random restart, without doing stuff.
boot animation....10 minutes..
restarted stuck at mi logo again.
not even the system is trying to get up.
now i can wipe verything, vendor, data, system, dalvik, whatsoever, i wiped everything, flashed vendor again, installed rom.
nothing... stuck at the MI logo.
any ideas?
many thanks
If you're flashing recovery ROM i suggest you use fastboot ROM

does not change anything , still the same issue.
seems that i cannot use any custom rom anymore. always stuck at the Mi logo.
i need to reset the whole phone via MiFlashTool once i installed a custom rom which ends up not booting.
rip custom rom...

From stock MIUI.
Install TWRP
Boot into TWRP
Do a factory reset
Format data - Format not wipe, need to type yes to confirm
Reboot to recovery (TWRP)
Flash custom ROM
Flash GApps if needed/wanted
Boot into the ROM
Everything should be good
Flash Magisk if required
Do not wipe any other partitions in TWRP, the factory reset is enough.
Make sure you format data in TWRP - don't miss this step out.
If you're doing this immediately after flashing MIUI, you must boot into MIUI once to finalise the installation.
Yes format data not wipe.
when i flash custom rom, even i am not on miui i first format data with yes in twrp then reboot to twrp. I put rom and gapps to internal memory, and install rom and gapps. and when finish reboot to system, when phone restart it stack at mi logo, so i have to go back to twrp and do again format data with typing yes, and then reboot to system and it works. so no wipe data, format data with typing yes.
oh and i thought, wipe is the same as format.... :/
works like charm. booted up successfully evo x with vendor 12 global.
Install TWRP
Boot into TWRP
Do a factory reset
Format data - Format not wipe, need to type yes to confirm
Reboot to recovery (TWRP)
Flash Vendor
Flash custom ROM
Boot into the ROM
Everything should be good
Flash Magisk if required
thanks all !

If you want to change to a different ROM, or if you want to update Evo x, then the safest way is to remove lockscreen security before flashing. This will remove encryption, which will allow you to clean flash a new ROM, or dirty flash an update, without any issues caused by encryption.
Once your done, add the lockscreen security back.

I'm getting the same problem, is there any fix?

problems with roms

(Im spanish, sorry if my english has errors or is really bad )
Hi, i've got a problem, I spent all day trying to fix a wrong rom installation but nothing works.
I was using Revolution Remix 8.6.2 and I wanted to try the new official hentaiOS, so I made a complete twrp backup of everything and I copied it to my computer, I wiped system, data, dalvick, and cache, and I flash hentaiOS rom zip. It was a normal bootloop so I just wiped all and restored the backup, but it didnt work (System had magisk with some modules but nothing happend in the previous reboots), so I rebooted into recovery to flash the clean RROS zip and try restoring only some parts of the backup to see which partition was causing the bootloop, but I was unable to boot into recovery, I used mi flash with miui 12 fastboot rom, it worked so I flashed TWRP again and tried to install RROS but nothing works.
I already tried with RROS 8.6.2, 8.6.1 and 8.6.0 but no one works, now Im gonna try with ArrowOS (It didn't work) but I want to use RROS, what can I do?

I found the way to boot RROS, I flashed the vendor of the lineageOS post
(Link: https://forum.xda-developers.com/k20-pro/development/rom-lineageos-17-0-t3976469 )
and after that I flash RROS 8.6.0, once it boot I reboot to recovery and started updating it.
Hope this info is useful for someone

Question [HELP] Doesn't boot with any Recovery based ROM!?

Hi Guys
I tried an update to Mirza's ROM but after it caused more issues, I tried restoring from full Orangefox backup in recovery; only to find the phone stuck at Fastboot mode. It appeared strange, so I tried it again to end up with same fate. I tried installing Xiaomi.EU ROM, but after installation it got into a boot loop alternating between Recovery logo and MIUI startup logo. I got into fastboot again and flashed TWRP trying the same, but without joy. Tried another recovery and multiple versions of Xioami.EU ROM all with same fate. Finally got hold of an old fastboot ROM from Xioami.EU and flashed with MiFlash tool and it flashed successfully without issues. Assuming all was well, I tried flashing ROM via recovery which either gets stuck at MIUI logo or recovery. Boot loader in unlocked and decrypted. I tried flashing SHRP recovery, Magisk, wiping data etc as well to rule out any issues, but the problems remain.
Any ideas as to what's happening?
If I understood right, recovery ofox is working.
So reboot to it
Format data with yes
Reboot ofox
Flash ROM
Flash magisk recommend
Format data again with yes
Reboot system and give time to boot, could be more than some minutes but I think not more than 20
For those who might face similar issues.
According to Orangefox website, 'note that you should not restore a backup of the persist image, unless it proves absolutely necessary'. I may have checked it in recovery during restoration which probably destroyed the partition.
Fix:Installed TWRP via flashboot, formatted all data(not wiped) and installed ROM then formatted again and it booted.
