Hello guys,
I just don't get it right. :crying: The Downgrade works but for me it is not possible to keep root after upgrading to jb.
I took the "WW_epad_user_9_4_5_30_20120907_UpdateLauncher.zip" and put it on my microSD. Renamed it to "EP201_768_SDUPDATE.zip" and went into recovery. The downgrade process started und I was able to root the TF700 with the "RootDebugfs.bat" method.
After that I installed the SuperSU app, started it and made the recommended update. I even marked the checkbox ota survival in the superuser app. Aftewards I loaded and installed the Voodoo OTA root keeper and said "protect root".
All checkboxes were marked and I hit the button temp unroot.
Now I tried to start an OTA Update but it always said that there are no updates available. I cleared DMclient and CMclient data + force close but no change.
So I took the "WW_epaduser_VER104425UpdateLauncher.zip" Update and updated it to jb again with renaming to "EP201_768_SDUPDATE.zip".
Recovery started. The update goes well but the OTA rootkeeper app is not able to restore root. -> No backup of su-binary available...
What am I doing wrong?!
Unlocking doesn't work either. Problem with internet connection, please try again later. Whats wrong with this tab?!
You tried to upgrade with the full firmware, this will wipe everything including root. You need to use the dlpkgfile incremental upgrade method or if the normal OTA still working it would be great just use the OTA rootkeeper to preserve root and let the OTA do its things.
