Is there any way I can install US Unlocked rom from the ruu.exe and use Sprint as a carrier? I've looked for a Sprint radio but the only ones I've found didn't work. I keep getting Limited Service. The phone is S-OFF, it has a super CID, I changed the phone's MID to match the one of US Unlocked.

Hi,
Tomorrow, I will be paying a visit to the US Cellular store so that they can unlock my phone for use on GSM networks. I usually run the unofficial build of CyanogenMod 12.1. But I learned that in order for them to unlock it I must be on stock. My question is: after I get it unlocked, will I be able to flash back to my backup of CyanogenMod without relocking the phone? I know on full GSM phones it's more of a hardware thing. But I want to be sure once it's unlocked that it's permanent.
(Also, I forgot to mention it's the US Cellular variant of the Galaxy S5)
Thank you!!
ROMs don't affect SIM lock afaik, or you'd be able to unlock them with a custom ROM too
Hello. I have been on the forum for days searching for answers for the sprint variant, which is hard to find solid proof of it working completely on gsm. Now for the verizon variant. If I buy a verizon variant will it work fully on GSM carriers like at&t?
Plus can it be fully converted? Including radio, to the US unlocked version? I have done it in the past with the at&t m8, converting it to unlocked variant with s-off, cid change, and ruu. I see tutorials saying to flash unlocked version to then reflash verizon radio. Will it work with unlocked radio? Or is it the same as with the sprint variant, where it always needs sprint radio?
Thanks for any help.

Thanks. I had read that forum, but since the guide posted says to flash verizon radio, I was wondering if you could leave the unlocked radio. After reading various posts afterwards it seems it is posible to not flash the verizon radio (keep the unlocked radio).

Correct, you can fully convert to Unlocked without flashing anything Verizon afterwards. Im using my Vzw 10 on a gsm network, converted to unlocked.

Thanks. I will look into buying the verizon variant. Did you also have to sim unlock? Or will flashing the unlocked version ruu take care of that? I truely doubt it, but I can not find any verizon unlocking service. And the only 10's I can find are locked to verizon.

Verizon 10 is not sim locked. You can take it, in stock Verizon form, and insert a gsm sim card and it will work. The real benefit of converting to unlocked is to have direct updates, have access to more lte bands, and best of all not have Verizon's bloated OS.
I bought this supposedly T-Mobile H918 on ebay. It says it works with T-mobile, Lycamobile, UltraMobile, Simplemobile. I figured (assumed (mistake)) the phone was unlocked. Tried to use a Freedompop gsm sim, no go. Went over to T-mobile they said it was NOT in database, couldn't unlock a phone not in database.but rep put his Tmobile sim in and it worked. I decided to order a T-mobile sim online for $10. In the meantime I went online looking for a LG IMEI checker. It turns out the phone is an Israeli H990. I guess someone flashed the T-mobile H918 on it. The IMEi is clear according to swappa and others. Should I send it back? It had H918 10K on it and I flashed back to 10J and rooted. I like the phone, but is it possible that it could get blocked down the line? If it's clear and can be used on different T-mobile MVNOs is it unlocked? I plugged IMEI into AT&T checker and it said something like, it's clear, we just need to get the right sim. Any help or info or ideas appreciated, Thanks Johnm

If you were able to root it, then its probably a database mismatch. The gsm simcards usually pose problem to T-Mobile's android handsets due to UICC activation (or UICC unlocking).
A crossflashed phone is hardbricked the moment u unlock its bootloader and load a custom recovery on it. (Had my chinese fake G3/G2 moments back in the days). Your phone is fine if you rooted it and its working right out of the box.
Two things that dont work if u modify the system of LG phones is RIL and the abnormal screen behavior. For your case, both work. I'm from Pakistan but I often end up having unlocked phones from American carriers. Right now I have Samsung Tab A which is from T-Mobile and UICC activation doesnt make my LTE Sim work on it. With T-Mobile its kinda common to end up into an "invalid sim card" error when u try to use a non-T variant.

Wow Thanks, this story is getting more interesting. I appreciate you relating your crossflashing experience. I guess I'll try to get some different gsm sims to try. Thanks, take care, johnm
I have a question. If I bought this phone outright, and sprint basically locked rooting it via boot loader version 5+, could another carrier flash it with "something special" to get it on the carriers firmware? If I own this, and Sprint locked a feature on me, wouldn't that make them liable for damages?

Not really. You bought the phone to use specially on Sprint as a Sprint phone. When it came out, no one knew about the u firmware or using it on other carriers. There is a post on here about unlocking additional lte bands. If the phone is carrier unlocked, you will get some service on all carriers, but not all the bands will be unlocked.
What's the easiest way to change over to global stock, with the phone pre unlocked by T-Mobile and updated to the latest already.
There is multiple guides and I'm not sure what's outdated or applies for my current situation? Is jumping to global back to T-Mobile again necessary with my sim already unlocked?
would like to know the answer to this as well. Just got mine unlocked by T-mobile and should have the bootloader unlocked by week's end
