GUI v0.91380069
- profiles now correctly load settings for models when switching only tabs.
- return to old scheme cid/color detection for db2020 usb operations (some users
reports that phone COLOR/CID can't be detected)
- added some models (w880,k550) so yes, yes. you must again remade profiles.
- db2020 empyboard filling supported (because i saw my "friend" on kukuruzer
takes money for that,while it is standalone process and not requires any
special moves, that is unfair and i shall fix it).
quick howto:
-go to empty tab
-select ANY db2020 model
-fill desired IMEI (or not fill if you have not want to write it)
-check WRITE OTP (or not check if you not want to write it)
-select CID49 (required)
-select needed brown2red erom
-press FLASH
-phone now complete retail (especially if you wrote otp) and must be
serviced as any retail db2020 phone (note - NOT USE EROM UPGRADE)
