Samsung SGH - 600 type mobile phone, its slender shape of small volume and was deeply loved by women, is more popular a kind of mobile phone in 99. This kind of mobile phone is one of the more common fault is a kind of can't boot, boot failure reason is caused, a hardware failure also have software failure, in the process of repair is not easy to find and judgment, and because the maintenance train of thought for the misjudgement of failure caused by incorrect, lead to economic losses.

Main block is code EEPROM (X24645, 24 lc64) system version IC (Flash lv800 29) and the data register (LRS1306) within the data error or component hardware damage caused, method of solving the fault is the three data storage chip off, to write the correct software data, then chip to put up your hand phone, failure can be ruled out. Due to production and sales region of origin time difference, so mobile phones have different versions of data, mainly entry procedure in the code block slice EEPROM parameters data and system version IC (Flash) should be relatively consistent, phone to self-check boot properly, so in the process of maintenance to distinguish writing parameter data version. There are a few points in the maintenance process must pay attention to: 6Gsservice manual download site

Lv800 29 (1), because the system version IC (Flash) don't boot failure caused by open welding very see more, best before they remove Flash rewrite data to repair welding of Flash, if can troubleshoot, you don't need to rewrite the Flash again, avoid duplication of work. 6Gsservice manual download site
