where did you download global os ?
from this thread, isn't one Global and another one European?
In your last part, how to wipe all data from the Settings? Where can I locate the option? Does it mean wiping all the previous Hydrogen Chinese ROM data?
I think you lose Hydrogen OS when you do local upgrade to Oxygen OS. re you questions: settings - system - reset options - erase all data. I did it because some people recommended it.
Thanks! just switched to international ROM in mins
do we have to wipe the data after that or it's ok to not wipe it ??
I do suggest swipe the old data to keep the ROM clean which helps performance a bit
Do you remember which Hydrogen OS version you had before the switch? Mine is 9.5.4, therefore I can't upgrade to the Global ROM 9.5.4 as the phone "can't be downgraded"...
Mine was 9.5.2, should not be upgraded to 9.5.4 Hydrogen ROM as the system would treat it as the latest version and forbidden the switching to International 9.5.4 Oxygen ROM.
can we use local backup option to restore after wipe ??
I did not try it but suppose the old data has been wiped and cannot be restored to the previous version.
Thanks for the feedback. Mine was the 9.5.4 as stock. So I guess I just have to wait for the next global ROM update
Emory I had the same issue .You can check how I solved it by upgrading to Android q beta I posted this before in the same thread. I'm not saying it's a great method but it worked for me
I followed your advice and it worked very well. It's actually very easy. Thanks a lot ! I'm in China but I did not have a problem with the system asking to connect to the internet. I just skipped it and then installed Oxygen OS. Happy to use my OP7 now with EU rom!
Glad I could help.
Added OxygenOS 9.5.5 related files.
thanks for your update
This is quite nice, but what will happen to the Widevine Level when flashing Global or EU OOS on top of Chinese HOS?
//edit: You check this with "DRM INFO" app, thank you.
Added 9.5.6 (global for now) related files.
thanks for you
