I'll try to keep this post as simple and well typed out as possible...
I cracked my screen and essentially damaged the digitizer as touches couldn't be registered at all, so I ordered a newbie off Aliexpress and using the guide on iFixit, I repaired it myself. It booted perfectly and everything works fine EXCEPT for a weird issue I'm having with my cellular data and the network itself not registering properly or something.
I've a SIM card and plan with Vodafone Australia and basically the phone:
- sometimes registers 4G/LTE, but never 3G and 2G didn't seem to want to work
- can sometimes send/receive texts (at random)
- can't make or receive calls
- cellular data absolutely doesn't work at all, nothing will load. I think there was only 1 occasion where half a web page loaded, but that could have been cached
- when the network 'disappears' either I just have a blank network bar in the status bar or sometimes I also get a triangle in the status bar and in the notification pull down area it reads "NO SERVICE - selected network (Vodafone AU) unavailable"
Prior to doing the repair I was using a Telstra 4G SIM and everything worked flawlessly right out of the box. Never an issue. I'm pretty sure both providers even run on the same bands.
I have tried the following to solve the problem, to no avail:
- different ROM and kernel (stock CM11S, Temasek CM12 w/ AK kernel)
- fastboot erase modemst1 and modemst2
- different modems (44S, 05Q)
- changing settings in *#*#4636#*#* menu (LTE/GSM auto, and the rest)
All I have left to try is to go see my provider and request a new SIM.
I'm thinking maybe something happened when I disassembled the device, like I may have damaged the part of the main board where the SIM registers. Could this be the cause? Surely not,as I do get that temporary LTE registration...
Also note that I'm 99.99% sure it's an international device, not a Chinese one, as it came with CM11S and the Aliexpress seller told me so.
Any advice? HELP!!!
