HTC 831c problems with bands when trying to unlock them - Sprint HTC One (M8)

I just use a thread to try to unlock all the bands of cualcomm I changed the value and forgot to backup the old one. Can anyone tell me that the value of Sprint htc an m8. NV 1877.?
Anyone who has this equipment that provides the original values?
Thanks in advance.
I can not write with qpst qualcomm, MSL error, I do not have SPC nor can I read it since it gives me message that it is a GSM device ..

SPC Cdma Diamond Unlock Help

1. Does anyone have the exact Address location of SPC. I would like to DUMP the Memory.
2. Does this model require CID unlocking to access the NVM?
Tested :
GetSPC.exe
PPST_KeyGen.dll
Input: HEX output: wrong code
Wrong SPC generated..
I am trying to use QPST...
Thx
Model: Diamond HTC
Carrier: Sprint
Technology: CDMA
1.- Yes, it requires hardSPL to flash custom ROMs, find it here--->http://forum.ppcgeeks.com/showthread.php?t=36062
2.- SPC address 018E:0190, you can read it using CDMA Workshop.

possible way to unlock sim

I think if any one have sprint one unlocked , we can unlock other sprint locked devices by comparing nv values using QPST app or another modem programming app.
because when sprint send unlock update it changes a value inside the device.
I am not a dev but I am asking developer if that possible please any one had his device unlocked please send nv tables to work on it.

[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

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

[Q] Unlock Sprint HTC ONE M8 HK (Domestic Carriers)

Hello,
I have been trying to unlock my HTC M8 HK for use with ATT or TMO, however i have tried changing the config.dat file, using OMAND sim lock methode and installed ViperOneM8 custom rom with no success.
I have tried both methods using lollipop, and 4.4.2 with no success, only with international carriers but no domestic.
If anyone has had any success please, help would be appreciated.
Thanks in advance.
To my knowledge the Sprint M8 cannot be SIM unlocked for use on other domestic carriers. SIM unlocking only works for international use.

Not even by Sprint itself?
Get your MSL code and try resetting data settings. This can be accessed by dialing a code(forgot which one) but I think its ##3424#

Opened EPST?Data Profile>Restore. Phone restarted
No difference.

Seems there is no way to allow for other bands to operate, looks like there is some sort of hardware or code restrictrion hidden beneath the firmware that we haven't figured. When changing NV Values the radio turns off, when trying to unlock sim, it does not allow any domestic sim.
Thanks for the help, but i'd call this closed for now.

[Q] How to make the Sprint HTC Desire 510 useable on GSM networks? (with sim card)

Hello, I have the Sprint HTC Desire 510 version. Im from Israel, And I've managed to get S-OFF and unlock the device with the Sunshine APK.
I Insert a local GSM sim, the device dosent seem to read it. Plus, I didnt activate the Sprint activate method. Will flashing a new rom will help to use the GSM sim? or theres some other method I should do inorder to make it work..?
Edit: Already looked at some threads here with the search option, But everything seems to be so messy that I can barely find something (If an answer, at all)..
Thanks a lot for helpers.

Ahh you again... I suppose you could try opening the phones dialing pad and type *#*#4636#*#* and then tap phone information and change where it says set preferred network type to GSM/WCDMA AUTO. Maybe that'll work.
