I tried to flash EU ROM from EU rom 13.04 to 13.05, using TWRP 3.4.1b.
Firstly, the zip could not be seen in internal storage, someone in XDA thread suggested I changed file system from ext 2 to ext 4 and back to ext 2, but now it failed .
The zip file is now in usb drive and I use USB-OTG to flash the zip file but the above three error appeared.
1.How can I solve it ???
2.If not possible, can I use fastboot to flash back to 13.02 with all the data, apps and pictures, video etc remain in the phone ???????
Thank you !
