U12+ stuck in bootloader/ twrp - HTC U12+ Questions & Answers

Hello there,
I´m stuck in fastboot with the message "Software status: modified" and "This device is corrupt. It can´t be trusted and will not boot." I have entered fastboot, then used temporarily TWRP 3.3.1.0 to flash magisk (root) and now i can´t boot. Stuck in middle between root and stock kind of... what steps are now possible to solve the problem of not booting. Do I have to do go back to stock by putting the ruu.zip on sd card and reflash in download mode or is there any workaround for the software status message. I don´t want to loose my encrypted user data by the full wipe of RUU. I also have to state that my U12+ was on the latest Pie Update (Android 9.0). At the moment I can enter fastboot, download mode and temporarily twrp, however i am not sure if that A/B security structure of the partitions cause that "corrupt" message. Thanks in advance!:good:

Since I ran out of solutions I decided to flash a RUU.zip and went back to stock. If anyone still finds a way to install magisk via temporary twrp on pie and to fix the "corrupt device" security message please leave a step-by-step guide.

back to stock firmware. stuck on bootloop

Hello,
i have a Huawei Honor 6X (BLN-L21):
Multitool picture while phone is connected via fastboot:
ibb.co/Ykk6DdP
I had LineageOS 14.1 installed on my phone but I was missing some of the EMUI features. I decided to go back to EMUI (EMUI5.0). Everything worked fine. After that I wanted to install Magisk with this tutorial: How to install Magisk (xda)
After flashing the zip with TWRP the phone wanted a password for decrypting. I entered my normal screen lock pin. After checking it was saying that the password ist correct but my files were corrupted. I had to click on "reset phone" which was starting something like "factory reset lowlevel" but the same issue appeared after that.
I decided to get the firmware BLN-L21C432B382 with the Firmware Finder and I am having trouble to install that. First I wiped with TWRP then installed stock recovery and stock erecovery but when I try to force install the stock firmware, the installation gets stuck at 5% and then skips all the way to 100% and restarts. After the reboot I can see the Honor boot animation but it restarts before the normal screen appears. I guess this is called a bootloop. Any suggestions about it?
PS: I already tried to use erecovery to download the right firmware but its telling me "getting package info failed"

Magisk - not able to decrypt data

Hello,
my setup first: Huawei Honor 6X with stock Rom (EMUI 5.0, BLN-21C432B382) but TWRP 3.1.1 flashed.
Everytime after I flash Magisk and reboot the device, it is asking me for my password to decrypt my data. When I enter my screen lock pin,
it says "checking" and then a screen appears which says something like "your password is correct but your data is corrupt" It tells me to reset my phone.
But instead when i go back to TWRP, i can still access all the data. I can see the internal storage and all the files on it.
The only way to make the system reboot correctly, is to flash the backup image of the boot partition.
Does anyone know any fix to this issue? I really want Magisk installed....
Edit: When I install version 18.1 instead of the latest 19.1, everything works normally. But many modules dont work with the older version.... this is not a good solution
No suggestions at all?

Stuck in a bootloop, please help

Hey,
Quick rundown: Stuck in a bootloop to some sort of empty bootloader screen which has the readout:
"Start/Restart Bootloader/Recovery Mode/Power Off"
"Press volume key to select, and press power key to select"[Regarding above options]
"FastBoot Mode
PRODUCT_NAME - sdm845
VARIANT - SDM UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - [Gonna leave this out for now]
SECURE BOOT - yes
DEVICE STATE - unlocked" [this line is in red]​
Every choice besides Power Off returns me to the same window. What can I do to recover from this?
Background:
So I was trying to update my OP6 to the current OxygenOS while keeping my root using TWRP and Magisk, which I've done in the past without any issue(i.e. go in recovery flash OS, flash current TWRP, reboot back to recovery, flash current Magisk as I understand it). However this time I was running into an issue flashing the Oxygen update getting an error that said it "failed to map file" for the zip. My first instinct was to update TWRP to see if the newest version didn't run into this issue so I flashed that followed by the current Magisk(no reboot in between). After booting back to standard operations everything seemed fine. I went back into recovery and tried the OS update again, but hit the same issue.
I couldn't find anything specific to OP6 with this issue, but similar questions with other devices suggested clearing the dalvik cache, which I tried to no useful effect. Then I came across this thread (forums.oneplus.com/threads/oxygen-os3-i-have-a-problem-please-help.440587/page-2 too new to hyperlink) and did what I think really messed me up which was boldly follow this guy's advice to do an advanced wipe of everything but internal storage(I also left USB storage intact) from TWRP. This failed to fix the issue with the file mapping error when I subsequently tried to flash the update, though I was able to flash TWRP and Magisk successfully again before rebooting and ending up in this loop.
Any assistance in fixing this or general tips on how to not be foolish when messing around with this stuff is greatly appreciated.
Update:
So I followed the advice gleaned from the resourceful person here(https://forum.xda-developers.com/oneplus-6t/help/bootloader-baseband-versions-blank-t3927565) to try working with the device from my computer with fastboot. At first it would recognize the device as "Android" but be unable to find a driver for it and adb/fastboot both failed to recognize it as a device. After installing MiniTool(more as a way to backup what was on the SD card) the proper device driver also got installed and I was able to access it with fastboot; I ran into similar issues as the linked thread above, solved it by switching to b(still failed) then back to a.
Currently I've got it booted into TWRP and I'm working on getting the current Oxygen .zip copied onto the phone storage but the transfer keeps failing after moving a negligible amount.
Update 2:
Via TWRP was able to sideload the current up-to-date standard OS onto it, however my Google backup seems to have decided to disappear on me and the only OP backup I have is ages old. Anyone have recommendations on data recovery tools?
next time just dont change the build.prop file.
serious, it just breaks the system.
heppened to me too.

Good to know, thanks for the info!
I assume that happened when I messed around with advanced wipe, do you know which of the folders I selected that would have been under? And just for future awareness, would that have not occurred had I just used TWRP's standard wipe instead?
You can run a program that will install 9.0.6 from scratch, running a batch file...
Save my life before yesterday....
Your device is bricked
If able to access the TWRP recovery then boot into twrp and try to get all the data stored in your computer.
Then use the Qualcomm flash tool to completely recover from your hard bricked OP6.
from here https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109
Then its easy, again unlock boot-loader flash TWRP and magisk.

Google Pixel - No apply update from ADB in recovery and other strange things

Hello everyone,
The starting situation is the Google Pixel of my mother was stuck on android 8.0. While showing there was an update available, the update would always fail to install after the reboot in the process. I found advice to factory reset the phone and then update, but this didn't help.
So my first thought was, if the update won't install the normal way I will do it manually. Google OTA installation guide says, get file (latest), reboot to recovery, plug in to USB, choose apply update by adb.
At this point the guide loses me, because the recovery screen I get to only lists reboot, reboot bootloader, simlock tool and device info tool (see picture). The device info will only tell "failed to update device info". The simlock tool just says "failed to enable simlock". Further while on this screen the phone isn't visible as an ADB device any more.
Next thing to try cause this didn't work was getting the image file (latest) from Google and flashing it through fastboot flash all, which led to a boot loop and the phone not starting at all. So I went and flashed back to the android 8 that was on it before and the phone booted again, but I'm still not any step further.
Next idea was maybe the recovery is broken somehow, so I went to install TWRP. Following the instructions I copied the latest version zip onto the phone and booted the img through fastboot. So far everything is fine, but when I install the zip I will get several errors about "can't mount /persist". And the installation won't work.
At this point I am out of ideas, so maybe someone here can tell me if and how this can be fixed? I wasn't able to find any information on this issue, aside from some xiaomi phones can show similar errors with the /persist partition and TWRP.
Any help would be welcome.

Afternoon matey, not to sure if this is helpful or not, may not be even specific to your device, but the error is the same error, so may shine a little light on the error.
