You can apply patches with jdflasher(DB2020 CID53 phones are not supported yet). If you have "bflash" and applied the quick access patch, then your phone is DB2020 CID52, and jdflasher can patch it.
To solve the first problem, follow this guide carefully: JDFlasher DB2020 CID52
There is something wrong with that patch file in line 1(probably a missing semicolon in front of first line). Please post the vkp patch, then we can help you with that too.second problem is that when i tryed to apply patch i got that error "error line 1"
