[Q] Best ROM & Modem for unlocking? - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys
I'm currently on 3 UK using 4.3 PACman and the latest international modem. I want to unlock my S4 and plan to use the service menu method. What is the best radio and ROM to do this? I am aware you need to use an older radio, but do you also need to use a 4.2 TW ROM, and if so, which?
Thanks

Bump!

currently have a Unlocked Wing and i'm using with AT&T.
I want to update my rom to the latest one, which I just download from Tmobile, but I was wondering if i update the rom, well the phone be locked to tmobile agian?
Sorry i'm a noob at this, but i'm learning ..
i wouldn't think so. the lock is held by the IMEI, which you gave when you unlocked your phone
But why update with tmobile when you can flash one of our custom roms

There's the breakdown of each rom. There are a lot of options out there. Yeah, I would stay away from the stock rom. The cooked roms give you a lot better performance.

[Q] how to find out which Stock Rom

Hi Everybody, i flashed my s4 i9505 without recording any information.
Now i want to flash the Stock Rom back, and i don't know which one to choose. Is there any chance that i can find out the Stock Rom i was using through IMEI code or SN?
Thank you in advance for helping.

[Q] lollipop official stock problems

Hi im a bit of a noob when it comes too this flashing business but i managed to update my i9505 to lollipop using odin and the official stock rom but the problem i have now is my network signal is now terrible where it was good before is ther anyway that a noob like me can fix this issue? Im in uk on giffgaff (o2)
i have never rooted my s4 before and if some one has a noob guide for rooting from lollipop so i can custom rom it up i might give that a look too, I wouldnt mind a nice slim custom rom with a few extra tweeks and without all the google and samsung rubbish that comes standard..
Thanks
P.s sorry for all the questions and sorry if this is in the wrong section
The signal problem is probably caused by the modem.
You have to flash the latest modem for your phone, country and carrier.
If you already are on the latest modem then a lollipop modem might help.
Here you can find a guide on how to root lollipop.
If you want a slim rom you better try CM12 or GPE. If you like touchwiz then look for a touchwiz based lollipop rom around the forum.

Is your phone branded or unlocked? Coz this is very important. UK(O2) still without lollipop update. This is the possible reason that you are receiving weak network signal.
