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!
Hello there, I posted a while ago because I wasn't able to update my HTC One nor connecting it to usb in any way.
Finally, now I was able to update it over OTA (wifi) and... well it still won't connect to USB.
Right now the phone is sitting at :
Android 5.0.2 Sense 6.0 software 7.19.771.21 and it's a HTC one 3
Strangely enough it's not sim locked cause I tried a vodafone sim earlier and it worked.
So, the main change here is that I was able to boot it into recovery mode but I wouldn't know what to do there.
Any advices on how to proceed to unlock bootloader, s-off and all that wonderfull stuff?
I reiterate that the phone WON'T connect in usb mode, not even in fastboot, looks like.
Thank you very much in advance

Already told you the last time that there is nothing useful in stock recovery, only factory reset.

Fix your usb port first. You must at least be able to use fastboot commands when in bootloader which requires usb connection.

I received an unlock code from AT&T to unlock my phone for use with other carriers so that I can use it when I travel outside the country. But it's not working for some reason. Here is what happens:
Turn phone off
Take out AT&T SIM card and replace with friend's T-Mobile SIM card
Boot phone completely
Phone automatically prompts me for unlock code which I enter
Phone goes to home screen
Phone prompts me again for unlock code
I tried 3 times and stopped trying because after 5 attempts the phone supposedly permanently locks to the AT&T network.
I AM rooted running CM13. Is that the issue? If so, what do I need to do to get the unlock to work? I tried searching but I'm only seeing results related to unlocking bootloader, etc, not surprisingly haha. Thanks!
Your system must be totally stock to SIM unlock the Nexus. Flash a stock image.

Okay to keep bootloader unlocked and keep root? Just need the stock ROM?
And then once I flash stock image and unlock SIM, okay to reflash CM13? And the SIM will remain unlocked?
Thanks again!
I wouldn't bother with root on the stock image since you'll be reinstalling your custom ROM afterward, but you can keep your bootloader unlocked without worry. Once SIM unlocked, the Nexus stays unlocked.
I cannot make phone calls or use the camera on my H811, currently flashed to stock H81120i.
I got from eBay a used, carrier-unlocked H811 with a bad ESN that I plan to use on AT&T. It was on 81110h when I got it.
I enabled Developer options, OEM Unlock, and USB debugging.
Code:
adb reboot bootloader
just rebooted the device, no bootloader.
Via LGUP, I flashed to H81120i KDZ, after which I successfully unlocked the bootloader, installed TWRP and then CM 14. I could text and surf (via wifi), but the camera and calling aren't working. I hadn't tested these features before.
Via TWRP, I installed a stock T-Mobile H81120i-Flashable.COMPLETE.zip. This did not solve the problem, so via TWRP I wiped everything but my SD card, and then re-installed that stock T-Mobile H81120i-Flashable.COMPLETE.zip. This did not solve the problem.
Via LGUP, I re-flashed H81120i KDZ. Still neither the dialer nor camera worked. Thoughts/help diagnosing the issue?
Should I flash a newer KDZ? Would this possibly solve it? I've tried to manually add an AT&T APN and set the network, but I cannot tell if that worked. When I request Permanent Unlock, the T-Mobile Device Unlock returns a schizophrenic answer. It says "Unlock Failed", then below that "Unlock Approved : Mobile device is permanently unlocked."
If this were a hardware issue, how would I prove it?

may be camera is hardware and calls cause of phone not beign unlocked.

Yeah, that's possible. Two different symptoms of two different problems.
I just did a factory reset on the device itself. I'll see if that does anything.

No, that didn't seem to get it either. Dangit.
Same Issue
I'm having the same problem here on the Tmobile network H811. I installed cyanogen 14 and even tried reverting back to lollipop stock kdz all to no avail. Let me know if you get yours working!

I was having the same problem and what fixed it for me was running the software update in the phone from 20i to 20o. Just go to the phone settings and check for an update. For some reason this worked perfectly for me and restored all hardware functionality.
Same problem here. I hope somebody have a solution.
Hello all,
I have a SM-G973F/DS (sold in EU) which has not been connected to the internet yet and no SIM card has been installed. Why? I would like to install a privacy friendly custom rom (IodéOS), and do NOT want to connect the device to internet, before I have installed IodéOS, and tweaked it.
But I need to unlock OEM under Developer Setting, but there is no option (not even greyed out). I have manually flashed the latest stock firmware with Odin (March 2023). I read about setting the date back one month later to enable it but this only works with connecting the phone to internet? I would like to unlock OEM offline.
Fastboot is not supported by Samsung, so
Code:
fastboot oem unlock
wiil not work.
Is there another method to do this offline? Thanks
