So I bought this HTC One M7, the guy claims its soft bricked and hes not able to fix it because hes technically challenged. So I take it home boot it up, its stuck in a boot loop so I boot it into fastboot the bootloader is locked so I try to connect it to adb, no luck, there is no driver on this internet that I have found that will connect to adb. So I resort to fastboot, I "fastboot devices" and sure enough it connects (wicked), first I try to flash recovery, I try to boot recovery, I tried to update zip, no luck in flashing anything because I either get a signature fail or a "remote: not allowed" then I realize my bootloader is locked, I try to unlock it "fastboot oem unlock" and of course I get a "INFO [ERR] command error". I also tried to change my cid to 11111111 and no luck. I have actually tried everything I can think of I cant get s-off to work my recovery is stock as well so theres no possibility of OTG cable plus a usb. My fastboot will not flash anything in fastboot, I cant push any files to the phone, I cant connect to adb, I cant use my recovery. So what in the actual can I do? I think i'm f**ked.
Thank you in advance for anything you can help me with.

You can't use adb unless you're booted to OS or custom recovery. Also you can't unlock bootloader with "fastboot oem unlock" unless your phone is GPE version. For Sense you need unlock token from htcdev. In order to flash anything, you need custom recovery, and you can flash it only if your bootloader is unlocked

I unlocked my htc with the unlocktoken from htc dev but it still says locked in bootloader. I can flash the unlock_code.bin but it does not restart nor does it come up with a message that says I would like to unlock bootloader etc.

can you post the output of "fastboot getvar all" (remove your imei and serialno). Sometimes, reflashing the stock firmware can solve some bootloader unlock problem but I need to know you getvar all before I can tell you which one you should flash.
So recently I tried rooting my xperia xp and it has failed horribly. I managed to unlock my bootloader and install twrp recovery but after doing so my phone could not reboot into system without running into a bootloop. I've tried to perform a software repair on my phone with the xperia companion, but as you know my bootloader is unlocked at the moment so that couldn't help me.
The issue with relocking here is that when I enter "./fastboot oem lock" on my terminal it replies as:
"FAILED (remote: unknown command)"
I really do not want to have to purchase a new phone just because of the bootloader, it'd be so so appreciated if somebody could help me out here
Also
I'd also like point out that I've also tried the other two commands I could find:
"./fastboot oem relock" and "./fastboot flashing lock"
There are two ways to relock bootloader:
1. Restore TA partition
2.Use Flashtool to relock
But if you encounter a bootloop after unlocking bootloader, try flash Magisk first.
Sony Xperia XZ Premium (single sim, G8141) owner here.
Is there really no way to relock the bootloader?
I don't have a TA backup. I have flashed a completely stock ROM with flashtool (Emma), I just want to relock a bootloader for a warranty claim (purely hardware, faulty USB connector, took me 20 minutes to get the computer to recognize it, at this point it won't even charge most of the time).
I have tried fastboot oem relock command even with the USB vendor ID that I also had to specify when unlocking it in the first place. New flashtool (Emma) does not seem to have any option to relock (or even unlock) BL, nor does it display any information about it. Old flashtool says TA read fail and that my bootloader cannot be relocked.
The boot screen tells me to please lock my bootloader so I'm assuming there must be a way, I just haven't found it yet.
Is there any way to unlock frp from the fastboot if the bootloader is unlocked and the device is bricked.
Already tried : fastboot oem relock xxxxx
Returns : command not allowed
I am on stock recovery and the device is bricked right now.
Help needed!Many thanks!

I was trying to install Camera2 on it. Unlocked it with developer options ->Unlock OEM
After try some things I reset factory the cellphone and decide to forget camera2 things...
So I went to developer options and LOCKED OEM.
After that I reboot in fastboot mode and did fastboot oem lock
Now the cellphone is locked in a bootloop saying that my deveice loaded a differente operational system and a screen to visit miui.com/unlock.
The unlock aplication doesn't work. Says that I can't unlock the device.
So that means I lost my crazy brand new phone? THere's any solution? The Test Point solution will work? Is that the only solution???
Thiank you for any response.

"So I went to developer option and LOCKED OEM" can you be a little more clear. Because unlocking the bootloader locks the OEM unlock option in the developer settings.
Possible cause of your bootloop is the change in your build.prop file.
I did a similar mistake as well. My phone was stuck in a bootloop. My mistake was that I installed Magisk and forgot to uninstall it through the Magisk manager before locking the bootloader and so the system were not in their stock state.
What I did was, I just booted my phone into fastboot.
Unlocked the bootloader again by using "fastboot OEM unlock". Went into fastboot again. Checked the current active slot by "fastboot getvar current-slot" and flashed the stock boot image from the stock pie rom found on Mi website.

What I did was with the phone working I entered on configuration, developer, and turned of the oem lock option.
Than I reboot in fastboot and did fastboot oem lock.
This made the cellphone unbootable. Bootloop saying that I'm trying to start a different operational system.
And I can't make fastboot unlock because I turned off the option in the system, so I can't send fastboot commands like oem edl, unlock, unlock-critical and etc...
I can't do nothing :/
I don't know how the option was working, but was... I know it should be locked, but this time wasn't. Was after I factory reset the cellphone
Your fault that you locked bootloader on a modified system. Do a research next time
Greetings!
As far as I know ASUS does not have a physical bootloader unlock counter like Samsung smartphones with their KNOX. This means that ASUS gets information about the unlocked bootloader via the internet when using their official unlock bootloader app. That is, ASUS gets the IMEI or S/N of the smartphone and puts it on their blacklist.
Is there any way to unlock the bootloader unofficially?
I really want to be able to get the bootloader back to its locked state and start getting and installing updates from my smartphone without using a PC as it was before the bootloader manipulation.
I tried these adb commands, but they don't work.
fastboot oem unlock
fastboot oem unlock confirm
fastboot oem asus-go
fastboot oem asus-go confirm
fastboot oem get_unlock_key
fastboot flashing unlock
fastboot oem asus-unlock working but i got error Verify unlock token fail.
