I have a Telecom Galaxy S2. I followed these instructions and rooted the stock rom:
This all went no problems. I then loaded Ginger Villan as I used that on my old HTC Desire and quite liked it.
I have always had bad cell coverage in my bedroom. After rooting and going to the new rom, areas where I previously got no bars but enough coverage to receive SMS no longer have any reception.
Has anyone rooted their phone and experienced anything similar? Can someone explain why this might happen? Does the carrier specific ROM have tweaks that affect coverage that a custom ROM may not have?
I had similar issues with my HTC Desire after rooting, I never really managed to fix it despite trying lots of different radio's. In that case I persisted, but while I like custom ROM's, the diminished coverage in my bedroom means its not realy worth the hassle.
