NOTE: The phone is S-off and locked (can be unlocked easily), in an attempt to solve the same issue.
Hmmm. WCDMA is an integrated data technology that works with GSM with part of the technology borrowed from CDMA. So most of the smart phones with 3G data capability will have GSM/WCDMA auto selection. Here the WCDMA is for either HSDPA or HSDPA+. If a phone is capable of LTE, then the options will be GSM/WCDMA/LTE auto selection. Well this selection is where I think my phone is goofed up. I vaguely remember playing with the data settings through "Battery Doctor" app just before it went for a toss.
@anilhotblood, yes if I select the "GSM/WCDMA/LTE Auto" option my signal bars vanish but not for few seconds, it vanishes once and for all . as of now I'm using it with GSM only option with EDGE only (very slow data) .
H! @Serupo, My bootloader is already locked. anyhow i tried unlocking it and then locking it again but it threw a command error while trying to unlock itself. and when i did a fastboot oem lock, it says the device is already locked.
