HTC U11 downgrade from Pie to Oreo

[kovsza]

Hi Everybody!

Im hungarian man and sorry very small speak English. Google Translate helps me.

I have an HTC U11 Black Dual SIM CID34 (4/64) phone. I opened the bootloader and installed TWRP the phone is S-ON status.
Everything is fine so far.

I copy the ROM to SD card and start the phone Recovery mode.

I selected the ROM from this list:
Link: Removed by System

I wanted to install this ROM
2PZCIMG_OCEAN_DUGL_O80_SENSE90GP_MR_HTC_Europe_2.33.401.10_Radio_8998-002772-1711161638_release_signed.zip
Link: Removed by System

TWRP always writes in an invalid ZIP format.
Your phone is not loading Android now. It starts to load but stops at the boot screen. I can boot my phone into Bootloader, Recovery, Download mode.

Thank you for your help!
Please if you write simply to write or step by step how to fix the phone.

Best regards: Szabolcs

Try renaming the zip file to 2pzcimg.zip,, and place it on the root of your sdcard and boot into downloader mode. Hth, this looks to be an ruu so it will put your phone back to stock and wipe all but the sd card.

I'll try and give you feedback.

I start the phone Downloaded mode. Phone autodetect the SD card ZIP file. I pressed VolUp buttons... and nothing.
Error message: FAIL12 RU_ZIP_ERROR

What's next?

If this is the problem then is there an easy way to set it to S-OFF?

This is the description I read. Based on what I described, I got to the version change. The version change failed. But in another place I read that in Download mode you can easily reinstall the previous version.

Then even that solution won't work.

Then even that solution won't work.

Like i said I have not tried it, as far as i know once you are on pie there is no going back unless someone else knows a solution

If You want to downgrade from Pie to Oreo. Its pretty easy and simple you has to follow same steps like Oreo to nougat downgrade but with some modifications:- (bootloader unlock is required)

1. I tried it on my own device it worked and it is s-on, So i don't know it works on s-off or not.

2. Download HTC Dev info tool from the below link

https://drive.google.com/file/d/1ubjDGNqCfIply-aRN8C7IQNb-YVkD4M7/view

3. Now connect your device to PC by turning on USB debugging in phone and open the info tool and click on GetDeviceInfo and it will show your device information in the tool.

4. If you want to change CID then follow this step otherwise skip to step 5. Change the CID to your desired CID and click on save.

5. Now change the misc version to the rom misc version which you downloaded for downgrade and click on save and apply changes.

6. Now download and install minimal adb and fastboot.exe in PC and open it and type "adb reboot download" and your phone boot to download mode and type "fastboot getvar all" and it will print your device information in the cmd itself and from their cross check your CID number whether it is changed to your required CID or not and also check the version number is blanked out or not. If it doesn't then something wrong you have done, so again start from step 2.

7. Download the Oreo RUU for your CID from the below link :-

12. Now open cmd and navigate to the com folder by using by using cd command.

14. Now type "htc_fastboot flash hosd hosd_signed.img" and wait for it to flash and after you see written successful then reboot to RUU mode by typing "htc_fastboot oem rebootRUU" l

What is the best way for change version number?

Edited the post and forgot to add changing the version number check from step 2 again. If that too not work run this command "adb shell dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=1 seek=2208 count=16" it will blank out misc version and follow the instructions i posted above.
