Flashing Guide
make back up of you data first!!!!!
1. Download Yan0s 53P firmware from
http://www.filefactory.com/file/9546bc/ and put in in empty directory - call it "FlashSource"
2. Download generic CGs from
http://www.filefactory.com/file/4e9c8d/
3. Extract files from Zip archive to empty directory - call it "GenericSource"
FlashSource dir and GenericSource dir NEED TO BE DIFFERENT DIRECTORIES!
4. Run RSD Lite and flash a phone from FlashSource.
5. Wait when RSD lite build CG files in FlashSource directory - RSDLite count percents to 100% and try move the phone to MBM mode with red flash screen.
6 At this moment quickly copy 4 CG files from GenericSource to FlashSource directory. This files replace defaults CGs from Yan0s firmware.
7. Wait for RSDLite message - Flash failed. It would be at 99%..
WAIT FOR Flash failed message - it may be long period of time.
9. Eject cable, then battery.
10. Insert battery and Run phone.
What change? Nothing important, only default FONT replaced by TreeSearch's one.. And than we receive as many symbols support as TreeSearch say. Vietnamize, normal Russian, and other. But keyboard is default.
Try it.. Make it for 3 phones with no problems.!
