In an attempt to use my locked AT&T HTC One phone on my T-mobile service I used the Cyanogenmod Installer to root my HTC one and hope to use it on the T-mobile network; I also unlocked the bootloader via HTC website. The newest Cyanogenmod is installed (11-20140417-NIGHTLY-m7) and wifi is working, etc. Unfortunately, no phone calls since it keeps asking for SIM Network unlock code (I bought an unlock code...not working). Any suggestions? What should I do? I did some research and I read something about using an RUU...is this a good solution? Thank you all!
Status of phone on bootloader screen is:
S-ON "TAMPERED"

No luck the phone they're referring to is the HTC Amaze it seems.
Does successfully installing Cyanogenmod "unlock" the network as well??

No, bootloader unlock and sim unlock are different things. You'll need to be on the stock rom to input your sim unlock code.

And that's what worked. Thanks!
Hello,
I (still) have the same problem here. I have a DHD that was locked and branded. I followed HTCDev's procedure to unlock the bootloader and installed a Cyanogenmod ROM (unofficial 10.1) two weeks ago that works great. I've been trying to get my phone unlocked for days with no luck ever since.
I've tried using the HTC unlock tool v. 0.9.5/4 and rooting the phone too. Nothing. Drivers are working fine; program executes as expected, but I still have a locked phone after it finishes. I got an unlock code that I enter after booting and I get a "successful network unlock" message, but the radio seems to remain off. I cannot place calls. Attempting to choose a network operator manually from the settings menu fails; I get a "mobile network unavailable" message when doing so (service providers list does not even appear). I've read threads saying that the only way to get around this is by reverting the phone to its original ROM and HBoot, but I've read elsewhere that workarounds on branded phones shipped with Gingerbread or Froyo (like mine used to run) fail and/or screw up the phone, so I have not tried that. Any ideas or pointers?
Thanks!

This thread is just for lollipop 5.x M8WHL (sprint) based on SENSE roms
LET'S START
1 - unlock bootloader from htcdev.com
2 - flash TWRP HERE
3 - ROOT your device by flashing SuperSU v2.45
4 - flash 1-HtcOMADM_SPCS.zip and then flash 2-HtcOMADM_SPCS.zip
5 - Install SIM unlock helper.apk and do as usual
If the signal didn't appear do the last step in this thread which is number 6 -

In file manager go to system/app/HtcOMADM_SPCS and delete a file called .fota_apk

I tried it and it worked. Just need to flash Kitkat and restore back the Lollipop after unlock.
hi , i needhelp with my htc m8 sprint
hi, i need help i got an HTC M8 sprint lollypop, from ebay i live in northern Baja In mexico , and i wanted to use it down here, i got an unlocking code but it does not ask for it, i have taken it to some shops that unlock cellphones but they cant do it
i love this phone but if i cant make it work i will have to re sell it,
can some one help???? many thanks
I have the same problem as arunkarnwal1981. I get the vdm client not responding error even after renaming the file in question (does it have to be deleted entirely?).
Also, SIM Unlock Helper just says "This device is not a Sprint HTC One." Odd, this is from an RUU dowloaded from HTC's site. So all I've got is a phone with the vdm client broken, whatever that is. Android is 5.0.2, Lollipop.
Oh - there's a brief message after "This device is not a Sprint HTC One." It reads invalid device htc-m8whl.
check my thread for complete Sim unlock on lollipop without s-off

htc m8 sprint,bootloader unlocked,s-off
hi there i tried this but it did not work, i have a htc m8 from sprint it has android 5.0.2
and i too want to use it out side of the US, mine its ROOTED,BOOTLOADER UNLOCKED,AND S-OFF, can you help me , it still does not accep my sim card....thank you
Well, it generates the vDM Client has stopped unexpectedly error as soon as I install the .zip. I'm running HTC's RUU of Lollipop 5.0.2.
And then the unlock helper says "This device is not a Sprint HTC One!" Process fails for me.
simple solution, works 100%
if u r on lollipop 5.0.1 or 5.0.2 on htc m8 sprint follow below steps to unlock ur phone
Unlock Bootloader
Flash TWRP RECOVERY
Flash Sim Unlock Zip file
Install Stock Rooted Deodexed 4.4.4 zip Rom file
wipe cache, dalvik cache and reboot phone, it will take some time to boot but hv patience...
Turn On the phone
Install sim unlock apk
Open and press 3 dots menu button and then wait for super user permission to be granted...
press back button and then start button... congo u will get ur sim unlock option at bottom of the page... reboot and then done... if u get vdm error then copy htc omad... file to system/apps and try again changing permission.. it really works i unlocked mine successfully...
In available networks I get an error message
Hi all. I have been following this post. I manage to get the sim unlock menu, then I go to GSM options and I manage to retrieve the lis of the following operators in my country, but as I select any of them, I get the message Your SIM card does not allow a connection to this network. Any clues on how to fix it? Thank you in, advance
Try to redo the unlock procedure and reboot the phone...i think it should work cuz its something related to unlocking,
Hi All -
I've searched everywhere for the answer to this and haven't been able to find it, so I figured I'd post here. This is the scenario:
1) I have a Moto X that is locked to AT&T
2) I wanted to give the phone to a friend who is on Sprint, so I paid for an unlock code
3) Even after unlocking and inserting the Sprint SIM, I still received the "SIM Network Unlock PIN" message
4) I now want to basically restore the phone completely back to the way it was (locked to AT&T), so it can be used with an AT&T SIM
5) I flashed the phone using RSDLite and the correct ATT ROM, but after the flash finished successfully and I insert a valid AT&T SIM, I still receive the same unlock message.
So my question is basically, can I get the phone completely back to being locked to AT&T, essentially the way it was out of the box? I'm also willing to flash it with Cyanogen or another ROM if that would help.
Any help is greatly appreciated, thanks for your time.
I have same issue, I had my Sim working for a couple of days but I wanted to return to stock to receive further updates and I flashed it with correct at&t firmware package but now there is a popup every time when I insert Sim about unlock code and I am stuck ... I think that's because of erasing modem st1 and modem st2 during flashing with RSDlite ... Is there anybody to suggest something helpful
Hi everyone,
I've been using an SM-920T 64GB Galaxy S6 bought from T-Mobile last summer. I did a permanent unlock using the T-Mobile application and since July I've been using the phone on the AT&T network. I just rebooted my phone today like I always do and upon restarting I got an "Invalid SIM Card" and it brings up a SIM network unlock PIN window that I can dismiss or enter a code into. What is going on?
I'm running XtreStoLite Deo 2.4 if that makes any difference.
Also, does anyone have the T-Mobile Device Unlock apk that comes stock with the phone? This is how I unlocked the phone in the first place but I don't have that app anymore since I run a custom rom, and the play store won't let me download it because I don't have a t-mobile SIM card in the phone.
Thanks!
Well for the benefit of whoever has the same issue. I flashed back the stock ROM via ODIN, ran the T-Mobile Device Unlock app, it said Unlock Unsuccessful in big, but right below it said the phone has been unlocked permanently. I put in my AT&T SIM and it was working again. Then I flashed back my TWRP backup and the phone remained unlocked. The non-Tmo ROMs get the unlock popup when a foreign SIM card is inserted, so getting an unlock code should work, but I didn't want to wait 3 days to receive one.

Can you tell me what ROM you used? I have the g920T also, and bought it USED unlocked from ebay, but it had the FRP (factory reset protection) lock on it. I had my US cellular SIM card in it, even though I was stuck at the "enter your previous used google account on this device" and the SIM seemed to work (saw the LTE bars above).
But the only way for me to bypass the FRP was to flash to the ROM to stock (which I used the G920T tmobile ROM) and I got to the home screen but now it says "Invalid SIM card. Network locked SIM card inserted" just how you were saying.
When I try using the Tmobile unlock app, it says "Server not responding. Please try again later." .
Please help!
