no i rebuilt imei using methode 1 for the second cpu i use methode 3 ?

For second CPU you must find 2nd CPU pinout. You can´t repair 2nd CPU with 1st CPU pinout. Open you phone, check if it have testpins (txa, txb, etc.) and attach phone using 2nd CPU (txb, rxb, GND) pinout. Than, you can use method 1 to rebuild 2nd IMEI.

In some cases 2nd pinout can be found.
Be sure that you have disabled pins that was already found by PinFinder for 1st CPU.
How to make it read here: http://www.infinity-box.biz/download..._PinFinder.pdf
See page 22

Hi! Try to restore CPU1 imei to the original.I had some china LT X3 models with same problem-CPU2 network works only if CPU1 has ORIGINAL IMEI.
I tried to format CPU1 and change CPU1 imei-after these operations CPU2 not working.After I write back original CPU1 imei-CPU2 works fine.

is it possible that the two cpu have the same imei ( original of corse)
