Hi everyone, Are there any way to get a custom ICS (JB is more preferrable) ROM to upgrade my 5-inch RK2918-based minitablet originally runnning Android 2.3.1? It's name Oysters Chrom 5500 and it is supposed to be a car gps with GLONASS and FM-transmitter, without Bluetooth and camera. The device's official page: Oysters (it is in Russian, sorry). Stock firmware: http://oysters.com1.ru/oysters/C5500/fw_c5500_311012_2nd.zip A supposed original device(s) description and images at OEM manufacturer's (PORTABLEVIEW ELECTRONICS(HK) LTD) website: XYA8550 and XYA8551. I've already rooted it and installed a generic CWM from fun_. The bad side of this generic CWM is that it can't mount anything hence I cannot make a backup. Any advices are appreciated.
