@mrt10001 I tried to flash from stock Android 9 image (https://oxygenos.oneplus.net/fulldowngrade_wipe_MSM_17819_181025_2315_user_MP1_release.zip).
I extracted the img files with payload_dumper, and flashed like explained in forums :

fastboot reboot bootloaderI rebooted, and now... the phone is really bricked (doesn't start anymore).
So bad... -
@reynald When you put it on charge and press the power on button, do you get the battery charging symbol, or an LED indicator?
-
@mrt10001 OK, I managed to restart it to fastboot mode (after some time...) and I'm downloading another firmware image since the previous seems to be... unusable.
Wait and see... -
@reynald Good news! I haven't bricked any phone yet when installing Ubuntu touch, but there are quirks that you have to persevere to work out (example is I could only get it to install on a Oneplus Three using windows and not Ubuntu).
-
You need the MSMdownload Tool from xda-developers forum. It will unbrick your device.
It's a windows only tool. In the forums here, there is a linux equivalent. Search op6 sub-category

@mrt10001 Got Mauronofrio ROM https://sourceforge.net/projects/fastbootroms/files/OnePlus 6/ and flashed 9.0.9 flawlessly, but the device still not booting (white LED on and nothing else).
I also tried to (fast)boot to TWRP.img, but same result : white LED and nothing else.
So the device is not "bricked" since I can access fastboot mode, but I can't manage to boot into anything else...

@reynald TWRP wipe and format to ext4 data, cache and system as on OP3/5 will that not clear it enough to just run the UBports installer?
-
I just reflashed the device with Android 9.0.8 with MSM Download, so Android 9 is running OK.
Switched to developper mode, unlocked, and then ubports-installer (0.8.8) says "Your device sdm845 is not supported".
On this page https://devices.ubuntu-touch.io/device/enchilada/ it's said this device sdm845 is supported, so what???
-
@reynald Sorry I have no direct experience of the OP6 does this this help at all https://forums.ubports.com/topic/5715/restore-bricked-oneplus-6t-on-linux
Don't know if anyone here could help https://t.me/WelcomePlus our install group, think you need someone with direct knowledge. USB debugging, MTP transfer and all the other stuff is on in the android side. Just trying to think of stuff. -
@lakotaubp OK, I managed to configure Android 9 and start ubports-installer.
The new problem is: ubports-installer recognize the phone, downloads files, and the 9/12 file has bad checksum and the whole thing fails:
error: download error: Error: Error: Checksum mismatch on file /home/reynald/.cache/ubports/enchilada/Ubuntu Touch/boot-caf5011e14b7d983ea9f2384ef2fc43c4937bbd0006b30ff1aa65c87ae2ef8ee.tar.xzI will make a new post for this issue

@reynald
Try using ubports-installer 0.8.9_beta1
It worked for me with OP6 and OP6T.
Newer versions 0.9.0_beta1 and 0.9.1_beta1 doesn't work either.
