Flashing Roms For Other Carriers. - Sprint HTC One (M8)

So I am under the impression reading around on here that even if I SIM unlock a sprint M8 and try to use on T-Mobile' network it wont work. Or maybe to be more exact it doesn't get 4G ect, and will be super limited. Well someone told me that is because of the ROM being carrier apecific and since they M8 is the same for all carriers you can flash a T-Mobile ROM on a Sprint M8 and it will work just fine. Is there any truth to this?

No it is not. You can only use cross variant stock roms if you have super cid and s-off too. Still i would suggest you to look for more clear answer but as far as i know if the cid and mid of your phone doesnt match with the software version you want to flash it wont do any good.

It's my understanding that you must use a Sprint compatible ROM, even if you are Super CID and SIM unlock for use on another carrier.

Never do that .. Even though you can flash tmobile rom on sprint , BUT NEVER FLASH A RUU . flashing a gsm ruu on cdma device will brick your phone .
Flashing t mobile rom doesn't unlock it or make it work with tmobile .
AFAIK Domestic sim unlocking is not possible for sprint variant.

question regarding flashing a GSM based rom onto a Sprint phone

I am trying to unlock the Sprint HTC one's sim card so it can be used with a international sim card. Sprint has sent me numerous emails detailing my phone has been unlocked on their end, and i do know for a fact that the config was pushed to the phone (had a friend at sprint check this for me) but the phone remains SIMLock Enabled.
My theory is, if i flash a GSM rom, and insert my international sim card, hopefully it would prompt me for the Sim Unlock code. Right now in a sprint rom, it simply states SIMLock enabled and does not give us any optino to enter an unlock code. I would assume that the unlock is stored in NV memory and would survive a reflash of a different rom.
So my question are:
1. can I even flash a GSM based rom from the HTC One Section?
2. Will I be able to get back to a sprint based rom afterwards?
3. Can I harm anything by attempting this?
Thanks in advance.
Sprint One is CDMA, you can't flash GSM rom.
You will brick your one...

Sorry, but what do you mean for Sim Unlock Box?
Are you talking about the pin or you have a SimLock branded phone?
If you have a simlock branded phone, i'm not sure that you can unlock this with an interntional rom.
However, i think no.
Kernel are different...
The Sprint One is a CDMA phone with LTE bands (this is what requires the sim card). The phone does NOT have the hardware to connect to a gsm/wcdma network. So, even if you could sim-unlock the phone, an international (or any other carrier's) sim will not allow the phone to connect to any other network/carrier.
The Sprint One will ONLY connect to the Sprint network.

The unlock works 100%. If you don't see "SIMLock enabled" than it was successful. Probably the phone doesn't support your phone's frequencies. Don't jump directly to the last solution, read the thread thouroughly

Ive been doing the process over and over again and simlock is still visible on the secret menu .... Elvis ive followed your guide perfectly i even know all the steps by memory ...if it helps here is the htc one imei 990001460590706
Please heeelp me
Delete your IMEI please, it's not wise showing it to everybody. If you did get s-off and than downgraded, did you root your phone and than tried the "Sprint HTC One SIM unlock helper" app? What did the app say? I'm sure you didn't do some steps otherwise your phone would be unlocked. Hundreds of people have unlocked their phone this way. If the "SIMLock" message doesn't go away you probably don't have a sprint one
Sent from my HTCONE using Tapatalk
The Sprint HTC one has blocked the carrier id's for domestic use aka att etc.. You can however if your s-off you can flash the initial release radio the first radio when the Sprint HTC was released and it will allow you to connect to domestic carriers. Here is the first radio released http://d-h.st/HHD I can pick up T-Mobile and att using the initial release radio, it is the only radio I could get to pick up signal with. The radio may be the reason your thinking that its not working, With any other radio you will get no signal and no networks avail. Your probably unlocked if you followed what elvisypi said, your just using the wrong radio. I would try flashing that radio and see what happens, I am in Ohio so i am using domestic carriers. Also make sure there bands in your area are covered.

Follow the guide posted above. After unlocking it you might have issue when connecting to other carrier s network so be sure they are using compatible frequencies. I'm almost sure you will not be able to connect it to any other CDMA carrier. Normally CDMA carriers will not accept a phone on their network if not sold by them.
Next time if you are planning to switch carriers, buy a gsm phone, much easier! even with a locked gsm phone, you'll only need to sim-unlock the phone with a purchased code then put in any gsm sim card.
Sorry I can't help you more, I'm not familiar with the WLS variant.

[Q] Help with international SIM Unlock (I can pay)

Hello,
I am currently living in Europe and i have a Sprint M8. Unfortunately s-off is not compatible with my phone (u might know about the whelp message).
I dont know even if this is possible, but if any of u guys has a contract with SPRINT, can you request an international SIM Unlock (GSM) for me (i dont need unlock for USA carriers, just for other international carriers)?
I can pay if the fee is acceptable.
Thanx!
first why would you get the Sprint version if you live abroad?
second sprint can unlock it so long as its payed off (not on someones contract) and hasnt been reported lost or stolen. just call sprint
Sent from my 831C using XDA Free mobile app
I cant call sprint from where I live. If somebody can do it for me im willing to pay.
I contacted Sprint from their Live Chat, and they told me i have to have an active contract with them in order to unlock. Which i dont have
Can anybody help?

if you want to try something on your responsibility then you can follow the sim unlock method without s-off (remember to make nand backup) & try if you get your device unlocked, if not then you will need to enable gsm band with QPST, with modified HTCOMADM_SPCS.apk.
I followed all that sim unlock method but my device still locked & i can't select gsm networks then i enabled it with QPST & all things worked ok.
the difference between us is s-off only.
I already tried it and the .apk files on /system/apps are replaced after i make the reboot. I guess this is why s-off is needed... I think i have to wait for the new s-off. Or till somebody with a Sprint contract will help me (if it is even possible since im in europe right now)

Try the following on you responsibility
- You should know your SPC, you can read it with CDMA Workshop or CDMA DFS Tool.
- Install QSPT (http://forum.xda-developers.com/showthread.php?t=2263391)
- enable diag mode ##3424#
- open QPST configuration, from port tab add your device diagnostics port.
- from start clients tab choose service programming then ok & click on read from phone.
- on system tab choose automatic for roam preferences.
- on UMTS System tab choose any for pref service domain & any band (last bottom right) for proffered band.
- click write to phone, then your device should work on GSM mode with modified HTCOMADM_SPCS.apk.
I'm with rooted, S-Off , bootloader unlocked HTC One M8 Sprint variant... I've even tried sim unlock... But it's still not accepting GSM sim cards... I think we need to have specific Prl update or UICC unlock for it to work

Sprint note, att service

I have a N920P sprint note 5. It is unlocked and rooted....i want to know if i could install a att rom on it. Im tired of seeing that sprint splash screen and i cant get 4g on it
I have sm-n920p and flashed the darthstalker rom which has several options for device selection during the install. I installed the tmobile version with no issues besides my network not working, it even listed device info under status as sm-n920t. Mine is not network unlocked but is rooted. If yours is unlocked and rooted I wouldnt think youd have any issues as I did not installing a tmobile rom. Maybe try a rom that has several or a few device compatibility. May or may not be a issue but I would feel safer with a rom that supported a few different models rather then a rom that was specific to a device that's not mine.
I understand exactly what you mean. Hmm i may try this later on today.

Didn't work at all or what did you run into? The first bootup took awhile but worked for me. I was on the noble kernel before flashing in twrp and had oem unlock enabled in dev options. I did the sm-920t choice and worked. Here is official pagehttp://forum.xda-developers.com/tmobile-galaxy-note5/development/rom-darthstalker-note5-version-1-aroma-t3212091
The sprint note 5 has different radio hardware than the other note 5's so to get phone calls and data to work you need to run sprint roms. Thats just the difference between CDMA radio hardware and the GSM radio hardware. ***SIM UNLOCK HAS NOTHING TO DO WITH THE CELL RADIO NOT WORKING ON A NON SPRINT ROM***You can use gsm service with a sim unlocked sprint note 5 as long as you are running a sprint rom. At&t has no root or roms for the note 5 so just stick to the sprint forum and you will be fine.
Right, my data did not work once I flashed the sm-n920t version but everything else seemed ok. I tried using a tmobile sim card and could not because my phone was is not uicc unlocked. He was saying his is unlocked and was wanting to flash a att rom which shouldnt be a problem from my experience unless 920p and 920t are compatible while the att version is not. I think the note 5 is capable of most networks gsm, hspa, cdma, lte, just need the right sim and the phone unlocked.
