Sim unlock possible with custom rom?

I have heard people saying after installing custom rom, it may cause problem sim-unlocking the HTC One. Is that correct? Have anyone tried that after installing the ARHD?
UPDATE: I tested it myself, and it works on ARHD.

I was impatient, and installed cyanogenmod and so on before unlocking the SIM, and now I'm unable to unlock it. I guess I'll try reverting to a stock ROM, attempt the SIM unlock, and then reinstall CM. If I can figure out how.

What do you mean by "unable"? It doesn't accept the unlock code, or what was the problem?

Yes, when you enter the code, it says "requesting network unlock... network unlock request failed"
I've just used TWRP to restore a stock ROM. This time, when I provide the unlock code, it tells me it succeeded, and that I need to reboot. Upon rebooting, the phone is network locked again -- not sure why the unlock wouldn't be persistent. If you decline to reboot, then I get a black screen with a spinner "Unlocking your SIM card and setting up your phone..." that doesn't seem to go away.
I'm not sure what to try next. Any ideas?

Hope other people can chime in. I don't even know if having a custom recovery will make a difference.

Well, all I did was a) unlock the bootloader via htcdev b) install clockworkmod c) install CM d) replace clockworkmod with TWRP to restore the stock ROM
So, I guess the next steps should be reversing b/d by taking recovery back to stock - not sure how to do that - and reversing a by re-locking the bootloader. If someone could help me figure out how to do those 2 things, that seems like a step in the right direction.

I managed to go back to stock recovery, and now the SIM unlock succeeds and is persistent. JOY!
Anyone idea if it's going to re-lock the SIM if I head back to clockworkmod & cyanogenmod? If it'll just bork all over again, then I won't bother, because I'll have to get back to this state again anyways.
Is there a backup solution that covers the ROM and recovery so I can more easily revert to this state later if need be?

Use a Guru Reset ROM to get back to stock (includes recovery): http://www.htc1guru.com/downloads/stock-rom-downloads/
the SIM Unlock code should work then.

Once SIM is unlocked, it won't lock again. you're good to flash anything.

Did a few posts for sim unlock a while back, but can't really remember exactly what had to be stock; you can try with anything you're on at the moment, if it doesnt work, then
1- just do a nandroid,
2- flash a stock rom matching (or at least very close) to your firmware & stock recovery
3- use sim-unlock code
4- flash back custom recovery
5- restore nandroid
and just in case, backup everything to PC after step 1.

[Complete guide] to SIM unlock your HTC One Sprint for free

After receiving many PM's I decided I should make a new thread to make the unlocking process clearer for noobs.
First:
Every Sprint HTC One can be unlocked, you just need a little patience and some basic knowledge. The unlock is PERMANENT, so you won't loose it if you flash another ROM, or even a ruu. The unlock works only on SENSE ROMs, so you can't unlock it on CM, AOSP or GPE ROMs. Even after you have unlocked you won't have network in non-sense ROMs.
Make sure your carrier frequencies are supported by the phone. Here you can find the HTC One's frequencies for Sprint.
Using US carriers will be a bit tricky, cause the frequencies the phone uses do not cover all the regions. You may loose network coverage often and may have problem with the roaming guards. Some users reported that the newest radios block domestic roaming, so you can try directly solution 3 which will downgrade your radio also, or downgrade it manually by flashing THIS radio in recovery. I also suggest you try BadBoyz ROM which has forced roaming.
The unlock works great outside the US though.
Background:
Before the release of 4.3 ROMs the process was very easy. If you still are on a SENSE 4.1.2 ROM with root access than all you have to do is follow this guide http://forum.xda-developers.com/showthread.php?t=2386703 or use the "Sprint HTC One SIM Unlock Helper" from Play Store
Now with the release of 4.3 Sprint made it more difficult. (Note even on the 4.4.2 base nothing has changed, the process is the same) The unlock uses a file called HtcOMADM_SPCS which was modified in 4.3, so the unlock no longer works.
Solution:
There are 3 possible solutions to this problem.
1. Use the modified HtcOMADM_SPCS made by @chas123 http://forum.xda-developers.com/showthread.php?t=2534208 You have to flash this in recovery and than the process is the same as with the 4.1.2 ROM
2. Use a file manager to replace the HtcOMADM_SPCS in /system/app with THIS.Than the process is the same as with the 4.1.2 ROM. After unlocking you'll get vDM client crashes. It's not a problem, cause afterwards you can flash any other ROM and you'll remain unlocked.
3. This is the longest way. Do this only if the previous methods fail.
a)If you are already S-OFF than:
-Download Sprint_HTC_One_m7wls_1.29.651.10_RUU.zip
-extract zip to a folder on your pc
-boot into bootloader (various ways)
-using fastboot, type this cmd: fastboot oem lock this will relock the bootloader
-from pc, run setup.exe from the extracted folder. it will run the RUU utility & flash back to stock
Now you have to unlock your bootloader, install a custom recovery and root. There are tons of guides for that. You can use THIS
b)If you are S-ON.
You can get S-OFF pretty easily on hboot 1.55 with rumrunner. Instructions HERE
The latest version of rumrunner HERE
If you are on hboot 1.56 or newer you can get s-off with Firewater http://firewater-soff.com/instructions/
After gaining S-OFF the process is the same as explained in a)
After you have successfully downgraded your ROM and radio, gained root you can go ahead and use the unlock. http://forum.xda-developers.com/showthread.php?t=2386703
How do you check if the unlock was successful?
Pretty simple just insert a SIM card and if you don't get the "SIMLock enabled" message than the unlock is complete.
You may still have no bars and be unable to make calls though. Make sure you change the settings in mobile data, network mode to GSM/UMTS. If still no luck than probably the phone doesn't cover your carrier's frequencies.
If you have signal, but can't use the internet make sure the APN settings match your carrier.

Just curious guys, If I'm correct, I still have an odexed rom, but that file I need to flash is only for deodexed roms. How do I go about turning my odexed phone into deodexed?

There is a simple fix for the sign. If you are on 4.3 and above use a file explorer and go to system/costumize/AAC/default.xml and change sku_id 10 to 42

kitkat bricked internal storage (0 mb)

i need your help, just got an htc one sprint for 90 bucks, i live abroad the US so i was thinking that i can use this phone without any problems as i have been doing with the verizon's phones with the global roaming. But with this when i put the sim card i got the invalid sim card etc, and i was looking the way to unlock it but spent almost all day and it seems that the version running kitkat and with hboot 1.57 can't get downgraded in order tu unlock the sim for use in my country, tired i can't remember what i did wrong that i just have now a bricked phone that can't get the internal storage, can't flash a zip even on sideload cuz i got errors, couldn't get the s off even using the firewater method with a custom rum.
I remember that i used an CM11 Nightless if i am not wrong but when i tried to restore it i got the 0 storage storage. Reading on different pages i just see the restore to the jelly bean version but kitkat i coulnd't get nothing. I am not so noob i had rooted even a Pantech Burst but this is a pain in the ass for me.
So i want to know if i have a brick or if this phone can be saved.
At least i can get to recovery when i unlock the bootloader but of course i can't get storage, tried with cwm and the other one
What i am worried about is that thing of security warning when i relocked the bootloader
Please help :crying:

You probably need to run a RUU to reset your phone. Here is 5.03.651.3 you can use this if your OS is the same or lower since you are still S-ON. On your sim unlock issue, depending if the imei is clear you can contact Sprint for the unlock code via their support site.

I have already tried that but i had the application has failed to start because its side-by-side configuration is incorrect, i downloaded the first one not the decrypted. Using both versions of windows 7 and 8 32-64 bits, happens the same problem
and for call Sprint i am in Panama, central america and i don't think that they will provide me the unlock code if the phone even is not mine at all it still with the name of the girl who sold me the one

Try to run the firmware 5.03.651.3 just download it, rename to firmware.zip and place in your adb/fastboot folder. Here are the steps for flashing firmware. Since you are S-ON make sure your bootloader is locked/relocked.
In bootloader/FASTBOOT USB type in the command window:
Code:
[B][I]fastboot oem rebootRUU [/I][/B]
NOTE: You should see a silver HTC logo come up on your phone after executing this command.
NOTE: if this command freezes, just disconnect the USB cable and hold the power and volume down buttons until the device reboots. Then, repeat the steps above again.
Then:
Code:
[B][I]fastboot flash zip firmware.zip[/I][/B]
Repeat the same command: IMPORTANT
Code:
[B][I]fastboot flash zip firmware.zip[/I][/B]
NOTE: The green bar on the phone may not go to 100% of the bar ... but If you see completed on your computer command window, wait for a few seconds and move on.
Last Step:
Code:
[B][I]fastboot reboot[/I][/B]

If the firmware flashes successfully, then I would try the RUU again.

Finally i made it came back but i still with the problem of the sim card, reading around the web it seems that with the hboot 1.57 is not yet possible the roaming as was possible with others like 1.56 or less, and i don't wanna have that pain again of what happens this weekend

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?

Hello i try to test on a HTC one M8 Sprint and this is what i get:
"Error: Activity class {com.redbend.vdmc/com.htc.omadm/test.TestMainActivity} dos not exist. "
the SIM_UNLOCK was apply via custom recovery, is rooted and have s-off, version 4.4.2.

since you're s-off you can try changing your CID, there is an all-in-one tool that will help you with that on the FAQ thread for the sprint m8, just change your CID to 11111111

i dont get you , isnt that for unbricking a device?

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

@jseb14

the apk will be attached
View attachment HtcOMADM_SPCS.apk

Via TWRP press Mount and mount system , now go back to advanced and file manager
In file manager go to system/app/HtcOMADM_SPCS and delete a file called .fota_apk

Help!
I'm running 4.4.4, when i clicked start in the sim unlock helper, nothing shows up. What do i need to do?

not working on lollipop....

Tested with your method and it didn't work but this did work
http://forum.xda-developers.com/sprint-htc-one-m8/general/sim-unlock-s-off-t3072722
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,
