Lightbulb Another way GSM Unlock for US Carriers and returning from d801 to ls980

So is there any other way of gsm unlocking the LS980 for US carriers (T-mobile for me) without being on the two specific roms that do this? Like say Vanir, or omnirom, or the Glex rom? I see the build.prop method mentioned a lot but not the actual process for it, and does that work for US carriers? Also, I flashed Justin's stock JB rom on my ls980 so its going to say its a d801, how do i go back to my ls980 status? I may or may not have accidentally my backup too... any way to undo this without using the lg flash tool?

justin posted a guide on how to port pretty much any rom from any of the other carriers:

http://forum.xda-developers.com/show...596175&page=41

Look for post #410 (credit to justin)

So far Ive tried the energy rom in the tmobile dev section and the stock international version (d802). Both worked well and I especially liked the d802 because it had the fm radio app and it worked great. Some other users have ported verizon roms as well.

Ive also tried the build prop method with modest success:

Look for post #423 and remember ti use lowercase "spr" (credit to MA7MOD_GSM)

Unfortunately the build prop method has a few quirks. You have to dial a "1" before dialing a number otherwise the dialing app crashes. Also I couldn't get wifi tethering to work properly. Eventually I settled on the energy rom and its been my daily driver for about 2 weeks and I cant complain much.

I dont know if you can successfully flash a ls980 and get back on the stock rom without lg flash tool. If you want to go back to stock Id stick to the tried and true method namely the stock tot file and lg flash tool. Follow the instructions here: (credit to hyelton)

Any idea as to whether trying the romn compare method listed in Justins instructions would work with the base and another sprint rom. I believe the rom is called d3rp or something similar.

Thats a good question. I cant speak from experience but Id imagine that any stock based spring rom would still have the usa gsm carrier lock. Now if I remember correctly some users have reported that using the build prop method then flashing a sprint AOSP rom unlocked the phone for usa carriers. Again I havent tired it myself but its somewhere in the unlock thread here:

Ah, I tried the rom porting method with an ATT rom but it woyldn't boot. It got past the lg logo and got stuck on a black screen and at the top left it said Fastboot and under that it had a number code. I managed to restore from backup using twrp but any idea what that was or how to get past it?

It was called something along the lines of grievous or grievious rom and yes, I wiped everything and I always clear both caches but it wouldn't boot and got stuck on the fastboot screen. I replaced all the necessary files although I did notice that the rom did not have the loki folder at all but I copied it anyway, is that maybe why that happened? Also, do you remember what other roms you've tried besides the energy rom?

Hi

Hi , I have flashed JUSTIN ROM posted in post# 239

It works fine , I have one issue and one query
- I can't set up any APN , by default it's T-Mobile. Even though I can add apn manually I can't select as there is no select button next to the apn.
Please note I am using this ROM in India/Airtel network (Need urgent help on this as no DATA is active)
- Is there any Kitkat version of this ROM

I have also attempted to use another ROM , following the instructions as per post #410
But after flashing my phone stuck in LG logo.
- Do I need to flash some other modem
- ROM which I were trying to flash is T-Mobile stock debloated (Kitkat) and I compared and did file adjustment against Justin's ROM (Sprint - T-Mobile , post#239 )
ROM link : http://forum.xda-developers.com/show....php?t=2688981
