Hi Guys,

We know most of the Chinese phones have problem after insert sim card ,Phone is shut down or Restart. and we can repaire it with Chinese miracle software 99% phones.
but still some phones after format(safe or Full) still same problem and we know its most probebly hardware fault.
But what should be failure?........ its CPU, Flash IC, Network IC, what should be failure on the mother baord?

Please guys if you have any experiance regarding this then share it here.

Regards.

most of the cases related to network ics.
before formatting dial 112 without sim, if phone restart or off,
then it is hw fault (network related)

Hello,

If you can not make 112/emergency call without sim-card (after format ffs) in most cases you need to replace PA (Power Amplifier).
