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.

How to Sim Unlock HTC One 802d Cdma-GSM?? Need help urgently

Hi guys,
I'm from indonesia, I bought HTC 802d in china last week. Before buying, i asked the sales person specifically if both the CDMA and GSM are unlocked. They said yes they are unlocked. I only brought my roaming GSM card and it worked just fine. Didnt bring my CDMA sim.
Came back to jakarta, put in CDMA sim and it said no service. FYI, i checked the cdma freq between indonesia and china, and they share the same frequency. So, i guess that the Sim 1 CDMA slot is being carrier locked by China Telecom.
I had followed all the intructions thats available in XDA, from unlocking bootloader, flashing recovery found on chinese web, installing ROM from chinese web, got my blinkfeed working in english, facebook & twitter also worked. Even perform S-Off using moonshine.
However, the sim1 slot is still showing "No Service".
Please help me with your expert advice. I need to get the CDMA working as soon as possible as the GSM part is only running on 2G and its internet is sooooooooo slowwwwwww....:crying::crying::crying::crying:
Thank your for your time and attention

No body have any idea?

I doubt I can help, here in the USA the CDMA is never locked and doesn't use a SIM card. On this side of the pond, only GSM uses a sim card. The CDMA phones that have a sim card here, is because the 4G LTE technology is a GSM, so their sim card is for LTE only.

Actually the above worked for me. After rooting and editing the build.prop the phone can connect to a CDMA network in Indonesia just fine. The only eyesore is that the carrier name doesn't show, it only shows its carrier code.

I'm in China at the moment and ended up picking up one of these today (HTC DESIRE 609d) which i was told was unlocked. 1 Sim card however seems to be locked to china telecom.
You managed to remove the lock? So I need to find a special DEV rom? if so could you please send me a link or point me in the right direction? Im a bit of a noob...
Cheers, Phil.

Hi guys! I also unlocked 1-st slot but it works only GSM card. my cdma R-UIM not work for this slot. Befor unlocking first slot I edited device nam settiongs with DFS. When I put GSM card to slot one and select cdma mode, phone use setting from device and pick up signal. but not incoming and outgoing calls (because there is no registered number to carrier). But in the DFS I choose "Only R-UIM" but phone not read the R-uim card. How can I unlock first slot to use my carrier R-uim card. (my carrier PerfectumMobile-Uzbekistan)

[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

SIM-unlocking

So this Summer I'm traveling to Europe for a month and would like to SIM unlock my phone so I can use a European SIM card to stay connected on the trip, I know I'll need to have it unlocked so it'll work, but Sprint only does a temp unlock for going out of the country and relocks it when you come back (I believe) and I figured, since I'd like to also switch to T-Mobile later, if there was a way to permanently SIM unlock? Also as a bonus, anyone know a good telecom company to use going through multiple EU countries? One where I don't have to get a new SIM everytime I go to a different country?

So when you mean that, just that I won't be able to use it with a US based GSM carrier? Any way to get around that?

there are no tested ways around that, In theory every htc one has the same hardware so theoretically speaking if you get S-off you could flash the factory unlocked's RUU and convert your phone to a complete factory unlocked model, that way you could use a gsm us carrier, you should note that before doing this you may wanna change the model id and cid as well, you could supercid or use any other unlocked variant's cid, but this is just in thery if you wanna go ahead and try it yourself it is not my responsability, once you're s-off you could hard brick your phone and end up with a paper weight

If I am soff, flash wrong ruu then in theory I should be able to flash back right ruu and recover, is that true?

Anyone to direct a link ?… of already SIM unlock ?…….. Ruu…. Am in superCID 111111??

the terminal command is wrong
After hours of research i was able to unlock it using other modelo phone threads
I didnt use this flashable zip I used the HtcOMADM_SPCS.apk found on a sim unlock thread, if you will i can upload when im home.
The correct command is
Su am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity
To unlock HK version simply do SuperCID flash reg sprint RUU versión 1.xx.xx android 4.4.2
And do the process, then freely flash back HK edición RUU also tested by myself

Can u direct me how to unlock ? it via… .dat apk… ..coz am already in superCID 111111 and S-OFF…. Plzzz
