Hi,
I had unlocked boot loader through HTCdev on latest GB stock ROM. So, obviously I was S-ON.
Meanwhile, I tried many ROMs but manually flashing boot image in hastboot.
I had following status of last running mobile when I tried to get S-OFF
Bootloader status: unlocked
S-ON
HBOOT 2.00.0000
Recovery: CWM
ROM: CynovivoX (JB 4.1.2)
Yesterday, I tried to get S-off by downgrading as per following thread
http://forum.xda-developers.com/showthread.php?t=1705913
There were lots of error while script was running, but one I remember was related to goldcard.
While running RUU, It goes well till I find something Error 131, Customer ID related and than exit.
After trying script and RUU many times, my status is
Bootloader status: Relocked
S-ON
HBOOT 2.00.0000
Recovery: ? (can't see or access anymore)
ROM: -
when running fastboot devices, my device is appearing
but in adb devices, nothing there
So, is there still any possibility to recover from this bricked state?
Desperately looking for expert help as I am not developer but somehow....tried this thinking would not be that difficult business....so help.
Try running the latest RUU and restarting everything over. Make sure to pick the right RUU for your region. The latest build number should be 4.14.XXXXX...
Also, in fastboot, your device isn't supposed to be visible with command of adb devices.
Another thing u could try is to unlock the bootloader again and see if u can access recovery again. Adb works in recovery

If you can get into fastboot but don't have a recovery installed, can't you just flash a new recovery? E.g. grab clockworkmod, connect your phone to your computer via usb and:
Code:
fastboot flash recovery recovery-clockwork-5.0.2.0-vivo.img
(obviously replace above code with actual name of .img file)
err this might be stupid, but click on bootloader > recovery.
Looks like you are already in a sub menu when you boot the bootloader.
The error while downgrading is related to you not relocking your phone before downgrading. Always relock before downgrading with an RUU.

Thanks all guys.
But problem fixed. I have unlocked the bootloader again through htcdev and it worked.
Now let me share issue for all other nondevelopers like me who may also face such issue...
runme script is suppose to push some files through adb commands and then reboot to fastboot mode to lock bootloader.
I had adb drivers installed as I got prompt from statusbar.
However still, while running downgrade script (runme), phone was not detected in adb mode and hence no file was pushed to phone. After reboot, phone detected in fastboot and OEM successfully relocked.
I am really surprised why device not found error not appeared and script not stopped. Later I came to know this by running the script without connecting phone and it ran with asking Q&A with found device, and also reading log file.
Then I ran RUU who wiped everything.
So, my device left without any ROM and with OEM locked. I can't access or install recover, ROM etc and RUU was having goldcard error.
Somehow tried to unlock again through token provided by HTCDev earlier (around 2 years back).
And thing become normal and in my control.
My advise: always check "adb devices" before running the script as I found script is misleading of found device and finally locking device. And if such thing happen, easiest one is to get in unlocked from HTCDev and restart whole process.

From what I'm reading, I'm getting a much clearer image of what happened. I believe your problem to be just driver errors...
The script itself is supposed to run regardless of whether phone is properly connected with proper drivers and whatnot. After all, it's just a set of commands in cmd.
But seeing as you ONLY got Error 131, you could have solved this by simply creating a goldcard.

Phone was connected in adb mode. This I can say by checking notifications in android and statusbar prompt in windows 7. While running script only, something got wrong getting adb mode not detected.
Anyway, Goldcard was also in my next line of action, but not sure even after creating Goldcard, I may stuck as version-main was not downgraded to 2. However, tried and got resolved with much simpler effort of unlocking through htcdev.
May be, I am also not that competent to understand developing world and only good enough to simply flash ROMs and updates as per instructions.
Anyway, thanks.
I'm on CM11 which has been working for weeks, last night my phone died completely and when I put it in the charger it wouldn’t light up no matter which outlet/cord I used. It reboots itself after a few seconds of being on, and so soon that I cant enter into recovery or select factory reset under recovery from bootloader because it selects recovery for me and then turns off. My Hboot is 1.44, S-on, its rooted as well. I have reached the edge of my competence, I'd really appreciate any and all help.

first try to re-flash your recovery to resolve
if not, you must flash stock ROM :
turn your phone on in bootloader mode or RUU mode (fastboot oem rebootRUU)
find your right RUU.exe from here > flash it
Note : you must flash the correct RUU that meet your CID & MID
if you can't know/find the correct RUU?, post your CID & MID

i dont know how to run adb commands when my phone wont turn on long enough to get registered by adb or the computer its on. it cant stay in bootloader for more than a few seconds, cant go into fastboot nor recovery. my radio is 4A 14.3250.13 and my phone is for AT&T, is that helpful?
it seems that there is nothing left to do with the phone. no fastboot, no recovery, no factory reset, no computer recognition. no adb/fastboot command gets the phone to be recognized. i have the latest htc drivers installed manually but when the computer recognizes there is a usb anything it tries to install the drivers but the phone quickly turns off and the driver installation fails. adb devices comes up empty, getvar cid keeps waiting for device forever, and trying to push files doesn’t work because it cant recognize it's there in the first place. is there anything I can do?
Here is the bootloader page I see if it helps.

I appreciate the help but I cant even get my phone to be recognized in fastboot or adb. It said "waiting for device" when i tried to get my cid for hours. It turns off too quickly for the computer to recognize it. Did you have this problem? If so how did you fix it?
I have a verizon htc one m7 that will boot to the verizon logo then restart. i can access the bootload/fastboot and recovery. when i issue the fastboot command of fastboot oem rebootRUU the command completes and phone goes black then the green htc logo appears and continues to try and boot normally. does anybody have any suggestions on how to get to the RUU mode? bootloader is locked and s-on is active. this is a completly stock phone.
I think you need unlocked bootloader (but I'm not sure). So try unlocking it (keep in mind that you'll loose the guarantee)

1- no need for an unlocked bootloader
2- he's on Verizon so he can't use HTCdev to unlock, and sunshine won't work without a booted phone

how about some background info, how you ended in this situation... if it's a complete stock phone (so you weren't messing around with flashing things), then it could very well be a hardware problem... but the above info isnt enough, you need to provide more details of how this came to be
it's also good practice to copy/paste the entire command prompt output, so we can take a look of what was typed and what the output generated
Customer bought the phone too me in a boot loop state.. he claims he was using it and it just went black then came back on but never fully booted kept restarting at the verizon logo. htc told him to try and factory reset the phone but that was a no go as well. i have tried a RUU utility and when the program says rebooting to bootloader it doesnt go into bootloader just trys to boot up normally. the same thing happens when i attempt to put it in RUU mode it just reboots and trys to boot normally.

sorry, dont get me wrong, but since i've been back (for a few hours), people are ... let's just say, not very forthcoming
what would help:
a screenshot of bootloader
a "fastboot getvar all" (excluding the last 6 digits of IMEI, MEID, and serial number... those need not be shared)
possibly a fastboot oem last_dmesg
though if the phone is completely stock, never been tampered with, then you have a high chance it's a hardware problem

thanks for the details, nothing "looks" wrong from those, but the "fastboot oem last_dmesg" has to be done after attempting to flash something, after a (non flashing reboot) it will just be empty.
couldn't find much, but have you tried this RUU:
http://forum.xda-developers.com/verizon-htc-one/help/exe-ruu-vzw-m7-4-4-3-s-users-t2919442
EDIT:
1- RUU.EXE will leave a log (before you close the .exe), in c:\ruu_log\.......txt
2- command prompt copy/paste is preferred to a screenshot, since it's much easier to read
good luck
So here's the story... this is an HTC Desire 510 purchased from Telus here in Canada. I've been messing around with different kernels, ROMs, etc. None of them really worked well for me, so I decided to go back to stock, unlock and try to sell it. Now I'm stuck at the bootloader and I can't figure out what to do. I tried to re-lock the bootloader so I could flash the stock ROM (those were the instructions I read)...
Whenever it boots, it gets to the recovery screen. ("Fastboot USB" / HBOOT) it says *Tampered* and *Relocked* at the top.
Then, when I try to unlock it with Unlock_code.bin (I have tried every method available), and say "Yes", I get the Fastboot USB screen with an overlay that says - at the top: Entering Recovery...
at the bottom it says: This build is for development purposes only, etc.
Then it just stays there until I remove the USB cable and the battery.
I reboot and I get the same thing every time.
Is there any way to fix this? I've tried many an adb command with no avail. I'm ready to throw this thing into the river.

What you need to do first of all is find an RUU for your device and then find the original recovery, not the twrp recovery but the actual recovery that was on the phone when you first got it. If you don't flash the original recovery then the RUU will refuse to continue and that's basically HTC's way of trying to prevent us from breaking the phone.. The unlock code you got from HTC you should have kept and whenever you sell the phone pass it along to the new owner.. So to help you understand everything I said first unlock your bootloader again and then flash the original recovery and then lock the bootloader again then run the RUU on the PC.. Some times you have to run the RUU a few times to finally get it to finish completely cause some times it'll hang and just sit there so just end the process and restart it but before ending it be sure you gave it enough time to try before thinking it's stuck because it may not be... After the RUU finishes, the phone will totally be stock again the same way it was the day you bought it..

HTC or Telus don't provide a RUU for the Telus version of the phone so I've been trying the Cricket version, doesn't work. It gives me the message: ERROR [131]: CUSTOMER ID ERROR.
There is some russian website that seems to have it for Telus, but you have to pay to access it, and I don't even know if it's what I need. ir-file.com (I can't post links)
So I'm not going down that rabbit hole.
I can't flash any recovery I find...
"fastboot getvar platform" gives me hTCBmsm2886
"fastboot flash recovery (*.img)" gives me a message saying FAILED (remote: signature verify fail) for every single recovery image I can find. Nothing works.

Did you try to reflash twrp? If I was in your predicament I'd flash twrp and then there is a rom that I configured to work great on the 32 bit phones it's the Modded CM11 and I'm pretty sure it'll work on yours albeit the cameras aren't working yet at least it's a start and you can find the CM11 I configured here ----> Modded CM11

Yeah, I tried to reflash TWRP, I get that message "FAILED: (remote: signature verify fail)"
That is after I type in the C:\adb\ folder "fastboot flash recovery twrp-2.8.7.0-a11.img"
and every other recovery image I can find, including older versions of TWRP.
This is why I'm frustrated, nothing works. If I could flash a ROM that'd be cool, but I can't get out of the bootloader, I can't even get into recovery.

I need you to type everything you see on your HBoot screen when you pull the battery and put it back in and then hold the volume down button and then press the power button at the same time and when the screen comes up type everything you see in here so I can see it... I think the reason you're getting the remote signature failure is because the bootloader is still locked and you have to make sure it really is unlocked.. Try that then get back to me.
Yeah, the bootloader is still locked. here's what it says:

Well if you had the boot unlocked before, why can't you send the unlock_code.bin to it and have it unlock again? Or did you lose the key? Because you're supposed to keep that key.. Did you use some sort of program to try and root the phone? Like them 1 click root apps...

Go download this to a computer/laptop whatever and connect the phone to it and try to run this RUU on the PC while the phone is connected to it and turned on in HBoot/fastboot... Do this before trying to unlock the boot again and if it hangs try it again because some times it can take 3 or 4 tries to get it to work...

Right it hung there because there was no recovery flashed so right after you unlock that no matter what just flash twrp to it the second after you tap yes to unlock the bootloader send the recovery to it.

You are supposed to be unlocking it from a PC and flashing the recovery from the PC also not trying to flash the recovery from the phone you cant do that unless the phones working.. Don't you have minimal ADB and Fastboot installed on a Windows PC?
I need to lock my bootloader to do an exchange at T-Mobile. I have 20R stock flashed, but it still says custom bootloader upon boot, how do I relock it safely?
I read that "fastboot oem lock" will work, but will brick it if I don't do it perfectly. Any advice on what to do?

ive done it .. it works. it will build dalvik once it reboots.
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore
I'm terribly sorry if bumping is not ok.
Thought it wasn't worth making a new thread, since my post is about the one above.
Has anybody actually tried these steps above? (Since every other thread mentioning this says it's a one-way only thing..)
Does locking the bootloader means also loosing the custom recovery? (I'd expect that, but asking to be sure)
Does it return the phone to it's original state? (ie. before one unlocked the bootloader, or there are some differences?)
Does it also means I would be able to get official OTA updates and so on? (since with a custom recovery, that's not possible)
Thanks in advance.
Yes, it does work. I did it, worked perfectly. Yes it does return your device to it's original state. Just make sure the stock ROM is flashed and all should be well. I didn't try, but I see no reason why it wouldn't let you get OTA updates from T-Mobile. Let me know if you need help.

Has anybody actually tried these steps above? (Since every other thread mentioning this says it's a one-way only thing..)
Does locking the bootloader means also loosing the custom recovery? (I'd expect that, but asking to be sure)
Does it return the phone to it's original state? (ie. before one unlocked the bootloader, or there are some differences?)
Does it also means I would be able to get official OTA updates and so on? (since with a custom recovery, that's not possible)
Thanks in advance.

ive said ive done it. on the above instructions you dont beleive.??
i think you loose the twrp phone doesnt show unlocked bootloader message did not check recovery but it must revert t stock one.. not sure about OTA since am not in tmobile network.
you dont need OTA. you can always download KDZ and flash it with LGUP.
and stay uptodate.

Thanks both for replying.
And no @raptorddd , I did not mean that.
Your post is the only mentioning that locking the bootloader is possible, while all the other similar threads have ony people saying otherwise / it's not possible. I guess a slightly doubt is legit to have, don't take it wrongly

ive done it .. it works. it will build dalvik once it reboots.
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore

are you sure you have h811.? i did not get that error ive tried this twice..
i remeber getting an security boot error on LG G2 i fix by flashing firmware .. so maybe KDZ could help..
if not am not sure then search for that error and find out how to fix.

My H811 T-mobile phone needs service. It has original 20v software version. It is unlocked with TWRP and rooted. Can I use this method? Do I first have to downgrade software to some other version? Will this method also take out TWRP and root or do I still have to take them out before doing this? How? Please help.

no need to downgrade. to remove root and any trace if phone works. is to use KDZ then once it boots into system do the lock procedure. so it locks and the small white letter are removed. this way its like stock rom and recovery and the above commmands will make bootloader locked. and sent to repair. if bootloops try the freezing method.
Used on an LG Aristo that has Cyanogen and it worked

This was the only one i found that didnt brick my phone and trust me ive bricked and unbricked this phone many times
When you use the fastboot command to lock back your bootloader, the phone doesn't revert automatically to the stock recovery and actually that is partly the reason why it bricks and other main reason is that changes made to bootloader to obtain root brick the phone. before you relock bootloader, if you have SuperSU (in-app menu option) or Magisk (uninstall zip file), use their respective methods to unroot the phone, then use twrp to flash .image file of stock recovery to recovery partition then use the fastboot command to lock the bootloader. Even then it may or may not work because if whatever method the phone uses to check the integrity of bootloader and/or recovery, such as md5, if it doesn't match, the phone will still brick. Since all your data on phone will be erased regardless as soon as you lock the bootloader, i personally just fastboot lock the bootloader, remove battery to power down, use the volume up and plug usb cable in from pc to put phone in download mode and just use LGUP (uppercut) if have kdz file already, which i do, i just let LG Bridge download the file, find it in programs folder and copy it to another location before LG Bridge deletes it --OR-- just use error recovery option in Software Update tab in LG Bridge as both LGUP and LG Bridge will detect the phone in download mode even if it is bricked.
By the way, I have used both methods above dozens of times without any issues, someone above who mentioned phone boot-looping because of locking the bootloader, it is boot-looping not because of hardware flaw which was widespread in LG G3 but a software issue (phone boots up, doesn't find the software configuration it is looking for and just restarts) and they are not the same issues, no need to freeze the phone, won't help.
the method works, but no OTA from T-Mobile. "verification problem".
When I try to "adb reboot bootloader" I get "security error".
If I try reboot recovery, TWRP is definitely not there.
Just want to update from20Q to 20X.
Any help would be appreciated.

The above points to you not giving permission possibly because either you missed the permission pop-up or selected option that didn't allow permission.
