I don’t have this device but a friend does. The R release, albeit slightly delayed, may be just around the corner and some users will need to get stock android 11 onto the device before flashing the new eOS-r.
So far, the best info I’ve found is this post from XDA
There are links in the original post to fastboot roms, but only up to 10.
On the last page of the there, post#1.252, there is a link to a fastboot image for 18.104.22.168, but it appears not to have been tested for installation yet.
In another post on the thread #1.244, there is a link to a guide for unbricking that looks interesting.
Windows seems to be favoured for flashing these roms by the inclusion of a flashall.bat that will do the work of flashing all the files automatically.It would be nice if there was a flashall.sh script as well but never mind. There is a list of all the commands for linux and I suppose it might be easy to incorporate a script if one had the knowledge. Otherwise one would have to do it line by line in the terminal I guess.
Anyone got any ideas? @Grendel I know you’ve flashed stock on OP6 before, how did you do that?
