My friend's A500s had some power on/off issue. So he gave the phone to Xolo Service center. After 25 days, it has come back with the problem fixed. But both the SIMs' Network are gone. Everything else works fine. It seems the Service center flashed his phone with Baseband Version Modem_XOLO_A500s_S014_13092013
The Phone Recognizes the SIM cards without any issue. But no signal. It searches for Signal constantly with "Magnifying Glass" like tiny icon over the Signal Indicator. And a tiny X mark for rest of the time.
FM Radio Works
Everything else Works
He doesn't want to give again to XOLO service center as he needs the phone for next week. He can't wait for another 25 days.
I installed CWM and Flashed with a Custom ROM but the Signal issue persists.
I would like to know what I should do to get the signal back...
1. Change the baseband or Downgrade it to 08082013?
2. Any other Custom ROM?
3. Any setting tweaks to be done?
or Any Hardware issue that we can't do/ Resubmit the phone to the same Xolo service center?
Right now, My friend can't afford another phone.
Kindly help me guys with your precious experiences and knowledge.
