Hello everyone, I am using an op9p with unlocked bootloader, and it is running oos 12 open beta2 now. Few days ago, Oneplus published a new update called C36, and I am trying to upgrade to it. However, each time I try to upgrade, I only got an "installation problem. Then I turned to the OxygenOS Updater, but even the update showed a "damaged file". Finally I download a file from the link, and I got a zip called "3a08e6de926493aedc3e04ee8b23476077c5b553.zip", which checksum is just like the pic

The expected md5 checksum in updater is "b121be03d8175bee2da76184a3719211", as you can see, it's different. But its SHA-1 checksum is just exactly equal the file name, so I am not sure about that if I have downloaded the right file now. Also, the local upgrade app can't see this zip.


Is there anyone already upgraded to the OB3? Or somebody can share his upgrade file? Thanks!

No dice. Afaik you need to use roll back zip, then flash ob1, ob2 and then ob3. Too much of hassle imo

I had a similar problem. From OB1 (rooted) I couldn't get OB2 installed using system update or the local update app. I tried flashing stock boot.img and vbmeta to unroot, but it didn't make any difference. Finally after OB3 came out (I was still on OB1), I reinstalled OB1 full zip using local upgrade app, took the OTA for OB2, then took the OTA for OB3 before rooting again. But now I'm probably stuck like you until the next full update is released (or we have to roll back for stable).

Problem is to me... Oxygen Updater is loading a confusing long named zip file and the lokal Updater app didn't find the zip file on phone. The Name of the zip is wrong or something like that. Other Updates zip files with typical name does it find.
