what is the difference Firmware and FullFlash backups in LGsw? - GSM-Forum

foony · 12-14-2004, 22:40

for example:

C1200
Firmware is 000000-7FE000
FullFlash is 000000-7FFFFF
this two files are the same from 000000 to 7FE000 and area in Fullflash 7FE000-7FFFFF is empty, only FF

or

C2200
Firmware is 000000-FF8000
FullFlash is 000000-FFFFFF
this two files are the same from 000000 to FF8000 and area in Fullflash FF8000-FFFFFF is empty, only FF

so for what is this FullFlash/repaire features? Cos I thik It is same as Firmware. Maybe will be good to add read/write eeprom function or relock funtion.

thanks for explain

Have you compared both flash files?

Hi.In LG phones,based on Analog Devices CPU most important phone data is called not eeprom,but calibration data.As now LG phones uses bottom boot block flashes,this data is placed in the beginning of the flash and can have
size 0x2000 or 0x4000 bytes.If in the future LG will use top boot block flashes,this data will be placed at the end of the flash,I mean at address,where firmware finishes.So this is reason why firmware and full flashes sizes differs,but they all now have same data
