same problem after rooting htc one s no wcdma
I would like to refresh the subject as I came across the same problem on my HTC one S (S4) and no one so far was able to explain what the issue may be
I have unlocked and rooted my device as described on xdadev guide, however I decided not to flash a new ROM and stayed with Vodafone UK stock.
I had a problem straight away as my phone would not connect to network or would show full bar but any connection failed (internet, calls, sms).
I found this post and red that switching to WCDMA only my help, it did, well for a while. I have used the phone for about two weeks and it was working fine but suddenly 2 days ago I realized it does the same thing as right after rooting - no network or full bar but any connection fails.
Over last two days i was trying to flash my phone with several different roms,factory reset it but non of this works.
Phone works fine on GSM but fails to search for any network on WCDMA or AUTO.
I'm pretty sure that this is related to rooting the phone as before it worked ok, no problems at all.
I can also confirm that its not sim, network coverage.
Does any one have an idea how to fix it?
