samsung no imei and no baseband

[concepttheman]

Do complete reset of Odin with the efs clear option. this will put you back to factory factory factory stock before they use even gets it mode. make sure you use the pit file also along with repetition and do not have a SD card in the phone. factory reset from the phone and the recovery. or have a dump of 128 megabytes from the same model and firmware phone and feed it in. that's the factory factory factory before somebody gets it stock. I made a mistake sorry

Hi, Is there any working solution for gt-19505 base band repair.. I have tried some different tactics but none is working. Z3x says no response from the phone.. though i have installed all the drivers.. my device is rooted and still i have that problem.. iEMi null/null
if there is any tested solution then post it please..

[phone.master1]

don't try with software......its hardware fault

[farog]

thanks but iold lik to nknow the part that have idea about pesband

[Antonio Lowe]

Let assume it is hardware
From existing experience, which part mostly need to be replaced?
Any measuring point to determine which parts?
If emmc still can read and write no error, can it considered good?
Measurement results guided by Service Manual
CP_VSD1(C352)=0.9~1.4V
CP_VSD2(C353)=1.8V
Some cases, I found no that two voltage n some is too low different from guide.
After replace baseband ic, it still same low voltage
Or somewhere cause it?

its most of the time, software problem and u can solve it with repairing the IMEI with nspro, z3x or octopus.
