| The second CPU should never be flashed! I said not once...the second cpu is a parasite one: in that second flash ic there are only the basic algo,RF data data and startup software.The operating software(if second sim is detected) is obtained from main flash ic.And this china units they are newer the same so the basic content may and usually is different.The solution to your problem is write back up,if you made one... The solution to second sim problem is : format full then write imei(from the back label).If it`s not working it can be hardware problem(sim reader error,Bluetooth malfunction and RF ic) |
