When you enter the command "adb pull/dev/block/sde1" in recovery mode, fastboot writes -"device unauthorized. Please check the confirmation dialog on your device." What's wrong?
[Downgrade][S-ON] Downgrade by flashing older version of official RUU
- Thread starter handsome_hell
- Start date
I'm trying to downgrade from pie to oreo, with no luck so far. I used the Devinfo_Tool from Sabpprook https://forum.xda-developers.com/htc-u11/development/unofficial-htc-u11-twrp-recovery-t3706264/page32 and with it I managed to change version. Now I can see my os number is 1.24.401.7, which is fine for me. But in download mode I see that os number is pie's (2.19.401.2). In sde1, though, pulling it with adb, I read 1.24.401.7. Weird. Still I'm not able to flash oreo RUU, getting error 12. So I tried to flash hosd_signed.img from RUU I'm going to flash as stated in this thread https://forum.xda-developers.com/showpost.php?p=79616165&postcount=1911, but I'm not able to afford it, fastboot returning error unknown. Tried everything found in various threads (switch USB port, switch pc, reinstall drivers, switch cable, etc) but still no luck.
Any help would be highly appreciated

Still I can't flash RUU. Can someone who achieved to flash hosd.img please explain how he managed to do it?
Fastboot reports file size is too large, while htc_fastboot, which I successfully used to flash larger files, stays pending 'sending hosd'

It won't work(or some steps are missing here.I spoke with HTC.Unfortunately they didn't seem to publish any full pie ruu.I need to make a clean install

@handsome_hell,
If my phone is everything from factory ( S-On, Locked bootloader, official software ), do i have to unlock bootloader to pull SDE1 file ?

This method seems to modify the original system version number so that the old version of the RUU file can pass the checking.

Backup your data before downgrading.

1. Download the RUU file which is the version you need.
2. Reboot to download mode, then flash the TWRP via fastboot.
Unofficial TWRP for U11+: https://forum.xda-developers.com/htc-u11/development/unofficial-htc-u11-twrp-recovery-t3706264
Fastboot command:
3. Reboot to recovery mode, then get sde1 file by :
4. Open the file with a text editor and change the version number, which is easy to found, to the version number of your RUU file.
5. Push back the file by
If it shows "does not have enough space", delete the original file by the files manager in the recovery first.
6. Flash your RUU file by entering into the download mode after copying it to the SD card.
Tested on U11+ China version, no problems found.

I don't have ADB tools for Windows...
Maybe you can try this:
https://www.google.co.id/amp/s/www.xda-developers.com/install-adb-windows-macos-linux/amp/1HTC U11 Plus is base on android oreo.
I think you can flash ruu normally.
You can flash older version of RUU follow software number and it's same version android.
If you want to rollback from new version android ,this method is important.
Ex RUU 1.xx.400.x Android 8.0
Your devices is software number 1.24.400.x ,Android 8.0
You can use Ruu above for flash your device.
