hmmm must be tested

latindor17 · Dec 12, 2012

4G Network LTE 1900?? I thought this phone would support LTE on 800 band... That's a shame considering Sprint is planning on moving it's spectrum from 1900 to 800.

Wow this is really exciting. What's the level of expertise required to pull this off?

CornholioGSM · Dec 13, 2012

....CAN YOU PLEASE TEST FOR ME INTERNAL SIM IC AND POST RESULTS?
Download from market Sim Card (gsmdev), then go to dial - then dial *#*#4636#*#* - then phone information - set GSM auto (prl) - restart and run Sim Card app.

Thanks

huge thanx for your advice, but the device is already bad esn and i am in another country...

funkym0nk3y · Feb 10, 2013

so i m just done with doing this mod and i can confirm that this doesnt work for gsm, heck it doesnt even stick to gsm only. It reads up all the info from the sim however but doesnt sticks to gsm network. The screenshots posted by OP are of photon q

I wonder if flashing a GSM modem from one of the other Optimus G variants would work? Or is the issue with the rom?

funkym0nk3y · Feb 10, 2013

I dont knw, maybe thr is a risk of bricking the phone by flashing some other variant modem. Can we try to flash the JB leaked rom ? The thing is, the network doesnt change to GSM, the sim mod is working CDMA sim card only which is pretty useless since we can flash the same on the phone

agurzhiy · Feb 11, 2013

First did you try to open *#*#4636#*#* and set GSM only?

and the second - someone was posting that he flashed Korean FW and everything was working except modem, thus try to do it.

This code does not work with the model LS970
to 3845 # * 970 #

agurzhiy · Feb 25, 2013

Both of them works!

ysabxe · Feb 27, 2013

So this MOD works with GSM... or not?
