Every time a user asks that, developer postpones new version for a week. Unwritten rule.

I'm sure if they donated or sent some money for beer (or vodka) over to the dev, he would be more willing--otherwise, his personal time is $$$ and y'all have nothing to complain about. People keep forgetting these devs are doing this as a courtesy to the community. :)

Hello!

I was trying to install a custom ROM in my HTC Exodus 1 but after installing the ROM Phone is stuck in Recovery Mode and I am also getting this message "This device is corrupt. It can't be trusted and will not boot."

I already have the stock ROM of HTC Exodus 1 but now the phone isn't booting into Download mode. Every time the phone is booting into Fastboot Mode only even when I switch to Download Mode, it restarts into Fastboot Mode again.

Please tell me how can I boot into the Download Mode. If It will boot into download mode, I will install the stock ROM.

If you don't know which partitions you broke, or which ones did you flash wrong files to, then just flash RUU.
You can also flash RUU in RUU mode, if all else fails. Type fastboot oem rebootRUU (if I remember correctly).

You are either doing it wrong, or your phone is FUBAR.
Have you tried flashing partitions manually one by one?
Yes. I tried but every time I get an error message "FAILED (remote: Erase is not allowed on PRODUCTION device)".

I also flashed hosd file but it's not solving the problem: https://forum.xda-developers.com/t/solved-cant-get-download-mode-working.3621434/post-72676351

Also, When I turn off the phone and connect it to the charger, the phone doesn't charge instead it automatically opens Fastboot Mode again.

Post a screenshot (like that one you posted) of executing "fastboot oem rebootRUU" and trying to flash RUU, so I can see...

When I type "fastboot oem rebootRUU" and press Enter, my phone just reboots again into Fastboot Mode.
IDK... Strange... Do you have TWRP installed? Tried booting it? You can use dd in shell via adb to flash partitions. Mihail suggested potential problem with vbmeta partition, so you can also try flashing vbmeta image and see what happens.

No. I don't have TWRP installed. And now the phone isn't even booting into TWRP using the fastboot boot FileName.img command. And whenever I try to flash anything including vbmeta, I get "Not allowed on PRODUCTION device" error every time.

Anyways, Thanks for the help. I hope I will find a solution.

originally you installed a custom rom in twrp? which one was it? the installation process went through without any problem?

so in the beginning it bootlooped to recovery mode, twrp, right? and after flashing the hosd.img you now cant even boot into twrp if i understood correctly? but since the flashing of the hosd.img was the only successful operation why not:
then try to reboot to download mode. If it does not work, try other firmware.zip but should be in the same build number at least X.XX.
good luck

Actually, I tried Beta 12 and Beta 13 ROMs from this thread and installation was successful but outgoing call wasn't working on both ROMs then I tried VOSP GSI. Again, VOSP installation was successful but this in this ROM incoming and outgoing both call wasn't working then I downloaded ROM and other files from this Video Description:
but I didn't want to Root the phone so I followed the video to install everything except Magisk Zip.

ALl files flashed successfully in TWRP from that video except Magisk then I Rebooted to system from TWRP but instead of rebooting into system, my phone rebooted into Fastboot Mode.

And, After this nothing is working. I can just flash hosd.img file but I haven't tried hosd.img from other firmwares because I don't know the build number of currently installed Rom. And I think I cannot get hosd.img file of third party Roms.

Hello, friends, can I modify the cid of ruu to implement cross version machine flushing without soff. I want to use the Taiwan version of ROM. Because of the language barrier, it is difficult for me to find the tutorial. Thank you.

Hello everyone!

I plan to release Android 13 ROM next week. There will be some important changes. First of all I've decided to move from AOSP to PixelExperience source code to have almost all Pixel available features on HTC U12+. At the current moment all looks fine. There are some camera issues with HTC Camera but I've noticed GCam works much better and in my opinion the quality of photos is better as well.

During the development there were some issues that were fixex. The biggest issue was reverting back FDE support to avoid erasing whole internal storage. But you still have to wipe data when upgrading from A12 to A13. I hope you will enjoy using ROM when it will be released.

For U11 users. I have tried to install current A13 beta ROM on my U11. I can see bootanimation and can take logs but still haven't figured out how to fix booting issue.

    [MANUAL] Fix CTS Profile Mismatch

    Initial situation: most GSIs are rooted to a certain extent. This also applies to the AOSP GSI, which is the basis of our ViperExerience ROM.

    Precondition: To correct the CTS mismatch, it is necessary that Magisk is installed.

    If the precondition is fulfilled, proceed as follows:

    1. Install the Magisk modules "Busybox" from Osmosis, and "MagiskHide Propst Config" from Didgeridoohan
    2. After a device restart, open a Terminal App on your HTC U12+ and go through the following steps
      • Request root privileges by typing
        Code:
        su
      • Start the Props module by typing
        Code:
        props
      • Type
        Code:
        1
        to set a new fingerprint for the device
      • Follow the instructions in order by selecting
        Code:
        f
        and
        Code:
        7
        (for HTC).
      • finally type
        Code:
        4
        (for U12+ Pie).
