Hello everone. I'm newbie here, so i am say Hello.
I have couple weeks DHO804. First what i've do that unlock with vendor file. Every thing went fine.
Second, i tryed to instal modded sparrow.apk (early version 0.21), and this step not went well.
New apk, is not to want install, but i've deinstalled the old one. Rigol stuck on "rigol" screen.
Fortunately i have maked copy original file and i installed back previous version (original).
From that moment i get often stuck on rigol screen, or blank screen, or rigol screen and then black without backlit screen
At this time, cannot to conect via adb to the oscilloscope. Just like brick. Sometimes (rare) boot normal.
I know in orgilinal GEL file firmware there is sparrow.apk, but i don't know how to repack. I thought install original one when
Rigol bootup normaly. Someone tell me how to repack GEL file? Or maybe other help?
For the records Rigol have waranty void stickers and i thougt not remove.
