Need help unlocking bootloader again....

So I initially unlocked bootloader and was going to flash recovery and a custom Rom, but I thought I read I have to relock then use the AT&T update to ICS and then unlock again. So I am at the point where I need to unlock the bootloader and it never seems to complete. I have left the command running for over 10 minutes but it doesn't finish. It did this before I upgraded to ICS but eventually did go through. This time it just doesn't seem to work. I have been booting into hboot, then switching to fastboot, the running the command to unlock,, but it just sits at that point. Anyone have any suggestions besides using the guide or the supertool. I have tried the guide and the supertool but neither is working now.
Oh yeah, this is on my new Vivid I just got. I'm not quite a noob as I have rooted my other phones.

Retry on the HTC dev site ....it might help u

Thanks, I tried again today and for some reason it went through smooth. Wonder if it has something to do with the USB port on one computer vs on my laptop. Weird, but I got it unlocked, rooted and loaded the Virtuous Inquisition ROM.
Thanks for the help.

[Q] HELP HTC One M7

I am a noob and tried to sim unlock my HTC one from Sprint and really messed things up, I erased the OS and no longer have TWRP access.
Let me start from the beginning, I have an HTC One (M7) by Sprint. I wanted to sim unlock it so I could use it with another carrier. I successfully unlocked the boot loader through htcdev. I then successfully rooted the device. Then I was stuck on trying to unlock the sim. I think I was unsuccessful because I had upgraded to Android 4.3, but not sure.
To make a long story short I kept messing with it and accidentally erased my OS while trying to use rumrunner. I had access to TWRP, which I had installed earlier, but as of today I no longer have access to TWRP, it just does not load anymore. I can still load into the boot loader usb section of my phone that’s about it.
I also relocked the boot loader because I read somewhere in another forum that I was supposed to do so.
So as of now my HTC one is Bootloader locked, S-ON, HBOOT 1.55.
ADB won’t recognize my HTC at all, I have another HTC (Different model) and ADB recognizes it so I know I have the drivers installed correctly, but it wont read the HTC One.
I tried using fastboot to flash a new ROM, and TWRP recovery but no luck, it stops at bootloader (Signature verify fail). So I can’t even push anything to the phone.
Can anyone please help? If you need anymore info please let me know.

You have to unlock the bootloader again, flash twrp recovery then sideload a rom.

+1 on the unlock
and get the recovery specifically for SPRINT, it's different than the GSM HTC One, you'll also have to flash a "close to stock" ROM to be able to use the SIM unlock code. no need to be locked!
and remember to get a close-to-stock ROM for SPRINT!!!

[Q] I think I screwed my HTC One.

So, I bought a second hand Sprint HTC One from Craigslist about a week ago.. First think I did was followed QBKing77's guide on how to unlock bootloader and root. Did that fairly easily, then went through this thread ( http://forum.xda-developers.com/showthread.php?t=2386703 ) to unlock it, had to do the steps in this thread ( http://forum.xda-developers.com/showthread.php?t=2491840 ) to get it to work since I had Android 4.3 and was unsure on how to go backwards to Android 4.2.2. After I got my phone unlocked, I went and got a Net10 SIM card and a month card, activated it, threw it in my One, and.. Nothing. No signal what so ever on GSM. It does recognize my SIM, though. So, I flashed to the original Radio from Sprint ( 1.00.20.0315 ), but still couldn't connect to GSM networks. I called Sprint, and they said my phone was still active on a plan, so I went hunting for a way around that.. I saw some things about flashing to Cricket, but I didn't want that. After relocking my bootloader and trying to RUU a few times, and none of them working, I thought I should update the Firmware. So, I downloaded some UL update for 3.62.401.1 without thinking, flashed it onto my device, and when I booted it up, it started a boot loop. I could navigate the phone for a while, but after about 5 minutes of it being turned on, it would reboot. So, I went into TWRP>wipe>advanced wipe> selected Dalvik Cache, Cache, and System. After that, my system now hangs on the HTC boot screen. I can still get into Bootloader, Fastboot, and Recovery. I tried flashing to TWRP 2.5.0.0, but my touch screen stopped working in TWRP when I did that. I just flashed back to 2.6.3.0, and my touch works again in TWRP. I can't get ADB Sideloader to work.. Currently, my Bootloader is Unlocked, S-Off, superCID, HBoot 1.55.0000, Radio 4A.21.3262.04, OpenDSP v32.120.274.0909, OS 1.29.651.10. That's about all the info I can get from Bootloader. It still says Tampered as well.
What should I do? My first step is to hopefully get back to where I can actually see the homescreen.. After that, I'd like to be able to get my phone to work on GSM.. I don't know if that is possible, though. I haven't found anything about someone having a phone that is still on a Sprint plan and being able to use GSM in the US.

I already have my phone unlocked. I have the same RUU downloaded from that thread as well, and tried it one more time, and I got Error 155, basically telling me I have the wrong RUU for my device..

Are you 100% sure you are s-off?
Try a different USB Port
USB 2 if possible.

I only have two ports on my laptop, and I've tried both. I even tried a usb hub, but that gave me the same error. In my bootloader, it says I'm s-off, I used rumrunner to do it a couple days ago.

[Q] Rooting Gone Bad on HTC One-Sprint

Hi all,
I've been attempting to and failing for the last few days to get a custom ROM installed on My HTC one from Sprint. About an hour ago, I realized what the problem was but unfortunately have found no way of fixing this.
So far, I have unlocked the phone using the instructions from the HTCDev site as well as installed CWM/ TWRP Bootloaders and rooted with SU installed. I wiped all of the information off of the phone and as far as I know, the original OS is no longer available. I am able to access recovery and bootloader mode no problem and can install ROM's but they do not work fully as prior to rooting, I did not turn S-Off. It is currently on and I am stuck on how exactly to proceed.
Ideally, I would like for some way to be able to turn S-off, however, because I cannot access the operating system, I have no way of running rumrunner to get it done. At best, I can turn the phone on for about 2.5 minutes before it reboots and repeats the process. Added to that, whenever I unlock the screen, only the HTC logo shows up, there's no way to access anything else. I am able to copy files to storage during that time though.
Alternatively, I would like to return it to it's original state, but trying that has failed on multiple occasions. All of the guides that I have seen to return to stock require that you either have access to the operating system (without the reboot) or have S-Off, none of which I have.
Also, during the time that the OS loads, adb does not recognize the device. Its recognized in bootloader mode and Hboot, just not during 'regular' operation.
I would appreciate any assistance that could be provided as I really need to get this phone working.
Thanks! :good:

Thanks! Worked like a charm. Don't know why it never showed up in my search results though. Just gotta get this phone unlocked for GSM now.

Another problem
So I finally got my HTC one from sprint unlocked but I ran into another problem. Whenever I insert a GSM sim into the phone, I cannot get any signal. An 'x' is shown over my signal bar. Have already flashed the old version of the radio but I still get the same result. Currently running viper rom 5.7. Bootloader is unlocked, S-off and rooted.
Any idea what else I can do? Got the PN 072 version if that helps
BTW, I am using a Domestic GSM sim

I REALLY don't get why people buy a CDMA phone to use on GSM networks.... That said this is a known issue if you're running KitKat. No solution last I checked.

Main reason I got it was cause it seemed like there was a GSM radio in the CDMA version and I travel quite often out of state. Being able to use it locally would simply be a huge bonus. Will try downgrading to 4.3 or 4.1 to see if there's any change.

[Q] Cannot boot into bootloader or recovery

Hello guys
So, here's the deal. Few months back, I messed up my One and got it stuck at the grey HTC Screen. Couldnt boot into system, because I guess there was no ROM on the device. Thanks to you guys here at XDA, I got the situation analyzed and took the device to an HTC Service Center who told me to get my motherboard replaced. That was way too costly, so I got it JTAGed. The device now boots into ROM, but it cant boot into the bootloader. So I cant unlock the bootloader, S-OFF, Root or anything.
I can only boot into ROM. Can anyone please explain why this is so and what can I do to get my bootloader and recovery back.
Any help will be greatly appreciated!
Thanks

Sorry for the late reply..i was out of town..
I tried adb and manually pressing power+down..but to no avail.
I figured it out in the end though...i dont know what happened but the device suddenly went into the bootloader one day and now its working fine.
I have a question..
My device has been jtagged. Its now bootloader locked, unrooted, s on.
Is it dangerous for me to try to unlock and s off and flash a new rom?
Can a device be flashed after its been jtagged? Im sorry I dont have much experience with jtag.
Thanks!
