Member: 148515 Status: Offline Thanks Meter: 19,534 | hello! i did little search on forum and i can say following: Very rare model. worth to start searching its pinout by yourself. start from opening phone and looking for marked test points on PCB. if no success- you must turn to 18pin connector. I would advice pin voltage measuring method described here: http:///vbb/attach...7&d=1187384324 |

Member: 55026 Status: Offline Thanks Meter: 53 | can you tell me pls? if I find corect pins when read info what I will get? the same as Rx1,Tx1 or what? and one more both IMEI are edited/readed differently, not at same time? one by one? For Ex. first we will connect Rx1-Tx1 to the box rx-tx than after finish the first step we will connect Rx2-Tx2 to the same RX-TX of the box, is that right?or maybe something else? what is the precedure? regards. |

Member: 55026 Status: Offline Thanks Meter: 53 | Now I got one more phone with 2 CPU. it is General Mobile DTS11. I found out both RX1,TX1 and RX2,TX2. I can read and change IMEI1 but infinity can not read or change IMEI2. but when make "Read Detailed Infiormation" software works and read all. this mean Rx2,TX2 is corect and working but infinity box can not read normal information from seccond CPU or maybe flash. it is also like KE970, when phone is on it does not read anything but when in boot mode it can read write data.. infinity team, could you please tell me now what to do? how to change seccond IMEI with infinity!? here is a log of detailed information for seccond CPU of DTS11: COM4 [VCP1] selected Device: Autodetect 6205-6227 NOR Checking data, wait... advanced flash detection enabled eeprom backup enabled, it may takes several minutes !
