Just want to make sure I understand the op's statement on supercid. I'm not currently supercid so if I unlock using this method, then down the road change to supercid. When I change back to AT&T Cid it will undo this method and be impossible to reunlock using this method. Is that correct?
[One (M8) General] killcreek:
You meant PAID METHOD for SIM UNLOCK.???? is there one ,>????
[One (M8) General] sharingspider:
First Soff then unlock
[One (M8) General] killcreek:
Yes I m having S-Off and tried all the mentioned steps to achieve SIM unlock but not able to do it successfully.

Tried simunlocker method..No luck

Tried config.dat method. No luck.

Any help is much appreciated. I have M8 Harman kardon edition
[One (M8) General] sharingspider:
If you are having S- off simunlocl has to happen. Can u tell what's the firmware version u on ?

Also what all UV done now?
[One (M8) General] killcreek:
Yes even i am wondering why it isnt happening.

Firmware version is 1.54.654.9 .

while sim unlocking using SIMUNLOCK helper, i get the menu where we need to select SIM LOCK. upon clicking back button, i am unable to see any successful message. just goes back to main screen and reboot the phone. After restarting, phone still remains locked.

Also tried Config.dat method without any luck.
[One (M8) General] sharingspider:
Post this reboot

Then dial *#*#4636#*#*

Select GSM Auto PRL and then back
[One (M8) General] killcreek:
Yes. Sir. I tried that as well.. Still no luck
[One (M8) General] sharingspider:
We r going wrong somewhere its jus not possible. Do one thing write super Cid to 11111111 hope u know the steps. Post that install an older ruu and try the steps once again.

SuperCID

Been a very long time since I have done anything to a phone (last time I used something from XDA I was still on my touch pro 2) and I just wanted to make sure before I try this. All I need before hand is root access, the bootloader unlocked, and s-off. Do I need SuperCID before or is that just an alternative to the permanent method and not needed?
[One (M8) General] killcreek:
Yes I supercid and ran the ruu.. same darn issue. Still SIM locked. I m not sure where am I going wrong
[One (M8) General] nrd\:
Confirm working for my m8.

EE UK M8 - unlocked using 3 UK sim.

Thanks for the guide.
[One (M8) General] rbouza1:
yeah i was wondering too, i havent tested yet
[One (M8) General] JEANRIVERA:
let us know the outcome please
[One (M8) General] GSLEON3:
Just curious why I'd want to do this? S-Off means I can very easily SuperCID the device. Once that is done, I was able to swap sim cards without issue, just like on every other SuperCID S-Off HTC device I've had.
[One (M8) General] JEANRIVERA:
That's not true, at least in the AT&T variant it ask you for a code once you put in a SIM card from other carriers
[One (M8) General] T3hBraveBoss:
Pretty sure you need to update your APN for AT&T
[One (M8) General] StuMcBill:
Is there a way to check if you are sim locked without actually having another sim?
[One (M8) General] JEANRIVERA:
there is none as far as i know unfortunately
[One (M8) General] GSLEON3:
I have an AT&T device. I picked it up at AT&T last Thursday, was the first one in stock at the LC, Texas store & the first one sold.

At any rate, I rooted, S-OFF, SuperCID & removed tamper banner, popped in a Tmo sim & went live. No sim pin....
[One (M8) General] JEANRIVERA:
NICE TO KNOW!!! i didn't supercid before attempting other sim maybe that is why it didn't work on mine thanks!!!!! but this still useful for those that doesn't want to supercid
[One (M8) General] rbouza1:
did it say failed couple times ? and then success
[One (M8) General] dsk00185:
I just tried on my M8 with both at ATT sim and TMobile. I get a message that says no sim at the bottom when I chnage to GSM mode only
[One (M8) General] JEANRIVERA:
I'm not sure but it could be that Sprint stock Rom doesn't have the necessary files to use the SIM tray or as I said it will only work with an international SIM card I'm no expert on CDMA devices, but you could also wait for [MENTION=1225716]Turge[/MENTION] and team for the ViperOneM8 Rom to support your device that might help but not sure
[One (M8) General] GermanGuy:
SIM Unlock worked. Thank you. When I ran the unlock, everything failed but the IMEI check which was successful. So obviously that was enough.
[One (M8) General] Rydah:
Successful on my Sprint variant, thanks! I'm a bit confused with OP.

"as pointed by [MENTION=372570]GSLEON3[/MENTION] you could only do the SuperCid "11111111" described bellow after S-OFF and it will also unlock your device but if for some reason you change back your CID you will lose the unlock the other method unlock the device forever."

So changing my CID unlocks it unless i revert but by flashing the Config.dat file, it's permanent and I can change my CID back?
[One (M8) General] JEANRIVERA:
Yes if you do it with the config.dat file way you don't need to have SuperCID
[One (M8) General] brar.arsh:
Here I can confirm that it only works with SD card.

If you use Internal storage, it will show "SD Init Fail"

and nothing after that.

I dont have SD card right now, will buy one and then use this.
[One (M8) General] vinylee79:

[One (M8) General] smokin901:

[One (M8) General] sinnedone:
Would be nice, Thas what I thought as soon as I read and get an Att prepaid plan or something.
[One (M8) General] JEANRIVERA:
One question why would anyone want to buy it from Sprint to use the device on AT&T if they are the same price out of contract and it is unsure if this unlock method works for Sprint One M8

Guys remember this phones works on 2 different technologys CDMA and GSM as far as I know if it works for Sprint device it will be only for international SIM card not US SIM card
[One (M8) General] hoang555:

You can't downgrade bootloader to do S-OFF because you need S-OFF to be able to downgrade bootloader so the only way is to use sunshine to do S-OFF go to theroot.ninja to do it then do the unlock procedure

If I unlock my device with permanent unlock method, could I flash and use any ROM without doing SuperCID?

Thanks in advance
[One (M8) General] leobg:
I was looking to unlock my Rogers Canada M8, it turned my unlock code was more difficult to obtain than unobtainium I guess. None of the usual unlockers were able to look up unlock code for me. So after wasting my time for about couple or so weeks with online unlockers with no luck, I decided to go S-off and use this method as last resort. Firewater couldn't do my phone but sunshine was able to get me s-off. Generated the config.dat and applied (no SuperCID needed). Phone is now unlocked. Thanks OP for the information!

I just want to know how you were able to unlock the sim. I have been at it for some time now and the install goes as planned, but when I put in a new sim card, I get nothing.

[One (M8) General] Brds7t7:
S-off and sim unlocking are two completely different things. You need to post in the firewater thread. If you can't S-off with firewater you'll need to use the sunshine method.

Firewater won't work on all M8's as htc have now patched it so the software won't work.

Paying for sunshine is the only way. if it won't work you'll need to post and ask in the sunshine thread as you can't sim unlock until S-Off.

I had the same problem as you, the menu didn't appear when I pressed start, but then I tried it *without* the modified HTCOMADM_SPCS.apk, I changed it back to the original one, and rebooted and tried the app again, ant then the menu appeared. If you still don't get the menu, maybe try it with a different ROM.

[One (M8) General] mrfury:
Hi.

A friend of mine is thinking about buying a HTC One M8, but as we live in Brazil, our only option is an international version one. SIM unlocking seems to be his only salvation to not pay US$600 on the device. If he purchases a AT&T M8, for example, and unlocks the SIM, would it be possible to use it with a brazilian SIM card?

He was thinking about purchasing the offer from Amazon: Individual contract with a 2-year contract ($80).

Best regards!

Guys, i am a noob in HTC. My HTC is S-OFF with CID HTC__039 running InsertCoin 3.0.8 ROM.

I tried the sieempi method and as per the steps I was able to Sim Unlock my HTC ONE M8.

But as soon as I insert a different carrier SIM, it detects the SIM, APN works (i.e manage to use LTE on my phone) but I cannot make/receive any calls though I could see network bar in the notification pane.

Tried with multiple sims but no luck.

unlocking sprint phones.

For sprint phones, Can we use the paid sites online that ask for our IMEI number and then provide us the unlock code? Are they really authentic or a scam? Is that a permanent unlock and if i restore my phone or install a new rom will i need to pay again for a new unlock code?

Does anyone know about this or has anyone tried it?

Would really like to know the truth behind those sites.

Thanks in advance. :good:

[One (M8) General] JEANRIVERA:
honestly i don't think to buy an unlock code will work for Sprint devices but i can assure that the site is legit and it is not a scam site, for next time if you want to use another provider in your phone buy a gsm model from a gsm carrier don't buy a cdma phone from a cdma provider even better you can buy it factory unlocked i am really sorry i'm not able to help you unlock your device
[One (M8) General] JEANRIVERA:
i know i did that if you notice i am the creator of this thread i never intended to cause any troubles and even less give false hope of an unlock that doesn't work on your device someone said it did work and that is why i originally added the sprint section but it gave much trouble than unlock that's why i did not removed but strike it for reference only for those that still want to try it from my point of view it is a hit or miss it has work for some and not for others

Well . Every thing in the original post was right except for new Sprint HTC one M8 which was purchased recently .

To get unlocked helper start key works you should rename all HTCOMADM files in the app folder plus all HTC OMADM PLUGINS ,

SO they are 4 files to rename not only 2 . And renaming should be changing name and extension . If you renamed only those 2 files mention in the op thread the start bottun won't work ,

Being on stock Rom is recommended plus installing the firmware mention on the above thread. It's 100% works on Sprint

I am using viperone Rom and it works excellent
