[HTC 10 Questions & Answers] HappyDrummer:
Hello dear HTC10 community!

My HTC 10 is driving me crazy right now and I'm at the end of my humble Latin and hope for your help.

Facts:

HTC_0034

ROOT (Magisk)

S-OFF

Radio: 2.0.U010241a@71204

OS: 3.16.401.2

CustomROM: Viper10 6.0.0

TWRP: twrp-3.5.0_9-0-pme.img (I also used the 4-5 versions before that in between)

About two weeks ago I installed a Magisk update. I think it was Magisk himself and not the manager. After the reboot, the device wanted a decryption key. However, I was only shown a text field, although I had deposited a pattern. Unfortunately, the way via the sample number code translation (point top-left = 1, top-middle = 2, top-right 3, middle-left = 4, middle-middle = 5 ... and so on) did not work. I couldn't get to my data. Regardless, I synchronized all important data with the PC every day via MyPhoneExplorer. So I thought to myself that I would put the smartphone back on. That started the madness ...

Part 1: Restore via TWRP

However, some later installed apps caused problems. Hence the ...

Part 2: ROM flash via TWRP

First I flashed the latest Viper10 6.0.0 ROM.

Since the developers of Viper10 are unfortunately no longer active and the Venom HUB server is down, the setup is no longer fun and my PRO license could no longer be restored - even after the selective restore of the entire Venom Viper- Modules via TitaniumBackup.

A little annoyed, I looked around for more CustomROMs.

Part 3: AICP, crDroid, CarbonROM & XenonHD

The first alternative surprised me with Android 10. WOW - I wouldn't have expected that with the old HTC10. I tried them all one by one. It's cool that some of my favorite functions (e.g. the 1px thick battery bar at the top) have made it into other ROMs.

Now I wanted to flash both candidates crDroid and CarbonROM again and examine them carefully,

From here on, sheer madness followed!

The home button on one of the two ROMs no longer responded. I suspected a hardware defect, but still wanted to test a different ROM. It didn't work either. Okay, back to the beginning.

Stock-3.16.401.2 installed. Both as Flash via TWRP and via 2PS6IMG.zip in download mode. The home button worked again both times. So NO hardware defect. In return, the mobile data no longer worked. WiFi but yes. I hadn't touched the SIM up to now and the smartphone didn't fall down either, which could have explained a wobble on the SIM. SIM removed, cleaned, slot blown out, SIM inserted, reboot: nothing. No funk.

One of the CustomROMs flashed, yeah, radio including LTE works again, home button too, but the GAPPS and the Google setup didn't work. Unfortunately, I need this because of some paid apps. The alternative with MicroG and the fake store unfortunately only worked for a few apps. So I wanted to let Google go directly to my device, because thanks to XPrivacyLua it had been fed with fake data for years and should continue to do so.

So a CustomROM flashed again. This time I couldn't enter a PIN on the first boot. The touchscreen did not respond to any touch. The softkeys responded, however. The hard keys too. With a 1-second press of power, the power menu even came up. But couldn't click anything.

Tried more ROM. Same problem.

With XenonHD the screen went on again. But again no home button.

From here on I just had to look at the device and I got in a bad mood.

Back to the beginning: Stock-3.16.401.2.

Everything worked! Great!

So now my CustomROM favorite carbon flashed clean.

No touch!

After the umpteenth attempt and once more stock ROM in between, the screen went off and was able to enter the PIN. So entered the PIN and bang, black screen. No reaction. 1 minute, 5 minutes, 20 minutes. The device got suspiciously hot. So off and let cool down.

Tried again. Same problem.

Back to the beginning: Stock-3.16.401.2.

Everything goes. But get a slight stomach ache using it without Magisk, XPrivacyLua and AFWall +.

And this has been going on for almost two weeks.

StockROM works (mostly), CustomROMs almost all hang completely in different places.

In the meantime I can hardly get beyond the bootloader (where the red warning is).

When it goes on, I see the boot animation and then a boot loop follows.

I also tried to re-flash the firmware every now and then, because there seems to be some driver problem here.

I found the only ZIP here:

Post # 2 at the bottom WWE Full_3.16.401.2_NoBootImg_Twrp3.2.1-2_firmware.zip.

However, this always caused problems when flashing. I have no idea what kind of error was displayed. I think it was because of the unpacking. Then left it.

The latest stock ZIP (2PS6IMG_PERFUME_UHL_O80_SENSE90GP_MR_HTC_Europe_3.16.401.2_R4_release_519849) contains the latest firmware anyway. So a clean basis should be created for a later CustomROM installation. Or do I have a mistake here?

What is going on here? Is there a limit to the number of flash operations?

Can't be that the device can only be operated with a stick.

In between the installation of the custom ROMs caused problems. But that always looked like errors when unzipping the images. After downloading the ZIP again, at least the installation went.

Basically I installed the ROMS from the external SD and previously deleted Dalvik, System, Cache, Data and Internal memory and formatted the data in order to really remove all remains of the previous installation.

I'm slowly getting fed up with the idea of buying the device new and setting it up based on its original condition.
