Hi, I still face the same issues.The only thing I can think of is you must've somehow messed up factory partitions, that's when I run MSM and fully rewrite ROM. Then when I start from there I'm ready to go. I've done it 5 times now before I got it right, haven't had a problem since. Maybe something's different about the versions we're using.
I got the advice to switch back to OxygenOS, but I did not got it back to work.
I followed the instructions above, but I am still in the "fastboot loop".
I tried several of the available (and here cited) recovery.img's (latest-OP11, Pixel, lineage and also TWRP), but none of them helped me to overcome the issue.
I copied several ROMs to the /sdcard, but the only ROM (incl. latest OP-11-ROM), which "seems" to install is lineage, but it is still not booting.
I have no access to Windows so MSMtool is currently no option. I suppose that there is an issue with the partitons, can you please give advice how to fix it with linux compatible tools?
Thanks a lot!
