Member: 44536 Status: Offline Thanks Meter: 0 | It could be your cable. Get a proper T28 datacable. Or make a service cable. After that, search for ATR 5.0 or 5.3 (without security box version) and you should be able to unlock it. No need to rewrite EEPROM. Just use FLASH function with appropriate .sbn file NOT .bin file. My mistake was I wrote the EEPROM using a downloaded .bin file which was not suitable to my model and later flash it with a Asian .sbn file, all the locks got removed but blank screen, phone worked. I later wrote the EEPROM with (luckily) the backup .bin file and flashed the asian.sbn - everything came back and 5 locks removed with full functions. Furthermore my T28s(European) was converted to T28sc(Asean) - with chinese language available. So its the .sbn file we need to FLASH (for lock removal), not the EEPROM .bin file. I had the same problem (timeout / unable to load...) until I ran program using a Toshiba 133mhz notebook running on Win98se (not Win XP or 2k - cannot recognise comm port or busy comm port with T28 datacable) and changed the T68 cable to a proper T28 datacable. Seller told me T68 cable OK for T28 but not so. Make sure your comm 1 or 2 port is free and corespondingly selected. Just a checklist .. and I solved my problem similar to yours. Hope this helps, novice or expert .. no one is too smart including me. |
