zuk z1 bootloop when flashing any rom

i flashed nuclear 7.1 but i encurred in a bootloop that i could resolve only with qfil tool, so i putted cos 12.1 stock, unclocked bootloader and flashed twrp, now: when i flash ANY rom via twrp i go in a bootloop that i can only solve with qfil tool going back to cos and do everything from beginning.
i tried:
change recovery (i tried CWM but i have same problem)
wipe storage (anything changed)
i tried several roms but everyone gave me the same result: very fast bootloop in zuk logo and phone vibration
the only thing i can do is to restore a backup, but since im note able to flash mm firmware (bootloop) i cant use touch id and g-sensor
what can be the problem?
any solution?
thanks

Boot and recovery partitions
Sounds like you messed up boot and recovery sections. Since you can boot up successfully, you may try to flash back to ZUI which changes these two sections completely. If it's not a solution for you, I think the only way to repair is completely format including kernel, system and partitions. You can find the tutorial on Website.

...
you can fix it just use TOOL_ZUK_Z1_ENG_0.0.6

Try flashing COS 12.1 via fastboot.

Hi!! I've flashed the NucleaRom too and for a couple of weeks it worked just fine. However one day, out of nowhere, the phone, while still on and working, restarted itself and entered a bootloop. After a few days it restarted normally and lasted a couple of hours but then it all started again. The BIG issue here is that when the phone enters in this bootloop where it remains on for about 15 seconds, it does it either in the system or the recovery/fastboot. I've managed to install two other ROMs via TWRP, when it miraculously remained turned on, but the problem persisted.
Is there a chance your problem was similar? How did you manage to flash via QFIL? I can't enter into that "emergency" or "download mode" in order to flash.
Many thanks in advance

i think that the problem is in the bootloader itself you should try flashing the latest os u have used and instal ordinary unofical lineage nightly (you can find everywhere) by this way your bootloader will be updated to 7.1 after that you can install any software i was having same problem when trying to migrate to lineage os

unable to install Custom ROM's
hi ,,
even i had the same problem like recovery was not accepting any ROMS... if we flash it ll go to recovery again and again,
and later i have flashed CM 13 with image file,, it worked and gone to recovery and updated the update to lineage OS 14.1 with Gapps..
hope it might help u...

Which ROM did you try and flash / install?
Try upgrading your TWRP to the latest version too.

I used partition dl mode to flash the stock oreo rom over 7.0 to keep the root. Then i flashed custom kernal for stock 8.0 but it didnt work. I have done the same procedure before and it has worked like a charm. But it keeps on giving the encrytion error when i try it now

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.

Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track...

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.

I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.

In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)
"Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track... "

Thank you for any guidance on this...

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?

Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!

As the title says, i can't to seen successfully boot any android pie/android 10 based rom on max pro m1.
>bootloader already unofficially unlocked.
but during erasing process, i accidentally booted into recovery from where i booted into system , where encryption started again.
>so i booted back to twrp, format data then flashed decrypt.zip
> then flashed havoc 9.0 based rom, gapps then >wipe from twrp itself.
> rom boots fine after boot logo,but after welcome screen, google loading screen comes after which screen goes blank black and finally shutdowns after few minutes.
>tried force shutdown, multiple times, data wipe,format data,decrypt.zip after mountung vendor as well.
Still same issue, just after rom boot logo finished loading, the phone just goes blank black.

So you don't use havoc anymore? Or did you first flash stock, update to pie, then flash havoc? I'm stuck too... Won't let me flash havoc, need to get firmware 16 or something.

Try factory reset or wipe data

That's not enough information. Can you link the ROM you flashed? Where did you come from? Stock firmware and if yes which version?
If you came from stock have you decrypted your data partition? (Twrp - Advanced wipe - format (not wipe) data - confirm with yes.
If possible provide a recovery log.

thanks for your kind reply mate.
rebooted to twrp and installed successfully.

[PROBLEM] Stuck on Android One logo

Hey!
I installed LineageOs on my Xiaomi Mi A1, everything went okay but when I installed the Gapps, it got stuck on the LineageOs logo. The volume button wasn't working right, yet somehow, I manage to enter TWRP and wipe that OS and restore the backup with the original Android One. But when I boot it, it got stuck on Android logo, unable to enter fastboot, TWRP or hard reset because of the volume button not working.
I don't know what else to do, to be honest...
p.d.: I'm new here, sorry if this is not the right section to ask.

Are you 100% sure that you have chosen right version of GApps? because i never had any issues with GApps causing boot loop. BTW what lineage os version 16 or 17 ?
I never had any luck restoring stock rom backup via TWRP either i have no idea why whenever i restore it will stuck on androidone logo.

I chose Android 10 GApps since I installed LineageOS 17. I thought it was the right version.
So TWRP can't be used for stock rom? I didn't know, maybe that's what got me stuck on Android One logo.
Any idea on how to get out from that loop? ?

Dont worry bootloop is not a problem download pixel experience it include gapps boot ur phone to twrp copy rom into internal or sd card Wipe system , data , cache and install the rom ..
TWRP should backup and restore stock image but i think there is something with this phone which wont let twrp to apply system restore i have done it 10 times and i failed everytime.
Edit: do let me know how it goes:good:

Definitely I'll try Pixel Experience! Seems like a good choice. I still need to figure out how to enter Fastboot or TWRP without the volume button.

Adb cmd won't recognize the device, so I'll have to boot it to EDL mode. Is there any guide here? I don't know how to do it.
