Hi there,
I need your help with my device which I just bricked in a peculiar way...
So, something I flashed was not correct. That resulted in an infinite reboot loop (the logo is shown for half a second and it reboots... endlessly). I just used the volume-up rocker to go into fastboot mode to fix the thing as I usually do. I booted into fastboot and this is where it become weird: I cannot do anything!
If I try to use fastboot continue, the phone reboots endlessly again.
If I try to boot to any img (TWRP or signed recovery or signed boot), the device tells me it cannot because it is locked.
If I try to unlock the bootloader (again, because it was), I am told that I am not allowed to do it. The problem is that I cannot boot into a ROM to go into dev mode to allow this.
If I try to flash things, it obviously doesn't work either as the bootloader is considered locked.
The worse here is that since my phone is "not" hard-bricked, I cannot go into qhsusb_bulk mode and use Qualcomm tools to unbrick the thing.
Can I still do something myself or am I screwed?

Still you can do that hard brick recovery method it will work for sure..switch off your phone completely and try to connect qhsusb mode.
I had no idea that I could force the qhsusb mode. It worked indeed. Damn ARM devices with their non-standard way of doing anything...

LG Escape running 4.1.2
here is the progression of events:
1. rooted device
2. root seemed successful and no malfunctions
3. backed up all apps and system data with Titanium backup
4. the lg escape has no way to unlock the bootloader, so I tried various other methods. one of which was entering recovery mode via terminal commands. this is basically a hard reset, and it wiped all my data
5. I restored all my apps and data from my external sd card with titanium
My best guess is this is where something went wrong
6. upon restoration it prompted me to reboot the device
7. reboot passes manufacturer logo, but resets when AT$T logo appears
8. as stated earlier, there is no way to enter recovery mode during boot.
9. there is a hard reset during boot, but mine will not work, as it requires touching buttons which do not seem to be active in my stage of the boot sequence
so, I understand this does NOT mean my phone is bricked, but I don't know how else to get it to boot back up, or what is even causing the boot loop, as I DO NOT HAVE ANY CUSTOM ROMS flashed. any help here is very appreciated!
EDIT: so I have attempted to use adb on my pc to reboot into recovery from there, but it occurred to me that while I was in recovery the first time, I never checked "usb debugging". as a result my adb console commands cant even see my device. any way to turn on usb debugging while locked in a boot loop?
also, I can get it to enter download mode. I was hoping I could just reflash the firmware to it without needing to enable usb debugging, but have no clue how to do that while locked out of the phone.
I realize this is a very specialized set of questions, but it is necessary to ask here as the most people will see it. im open to any ideas

i have now tried to flash the firmware while in download mode using a less than legitimately obtained lg R&D tool. however, i need V10F_00.kdz and i am facing a bit of censorship. any kind soul willing to host this file on dropbox or similar so i can download it?
Usually devices have a button combination to press when powering on to get into different modes. Maybe try searching for the button combination of your phone on Google? Try ' lg escape button recovery ' ?

believe me i have. the only combo i can get to is download mode. there is a combo for a hard reset, but my touch buttons arent active during boot.
I apologize if this is in the wrong place, and I've really tried searching around, but nothing seems to work/ is tailored to the m8.
So, I just got an M8 new out of the box, rooted it and successfully installed cyanogenmod. Problem is, I was playing around with it, trying to get the GApp store and somehow (did what i think was) deleted my roms completely. Now upon booting up the phone I just get the "This build is for dev..." screen, and with the volume down+Power button to access recovery mode I constantly get put back to the fastboot screen. I tried flashing a custom recovery as in "Phone arena CWM flash recovery" guide, but no luck because my computer is reading the device as offline. I honestly have no idea what to do, and if anyone could help me I would be so greatful...
TL;DR: Stuck on boot screen, can't enter recovery mode, think i deleted all my roms, help please
On a scale of 1 - bricked, how bricked is my phone?
HUGE DEVELOPMENTS, GUYS! I've been able to access recovery mode again by re-flashing ClockWorkMod.

On that scale, you are zero. If the screen comes on, you aren't bricked.
So my friend was trying to get some stupid game to work on my phone that my phone didn't support, so he tried replacing the build.prop for my Pantech Flex with one for the Galaxy s3. Which needless to say bricked it.
I can start up the phone, and I assume it starts up normally and goes to the lock screen. But everything after the pantech logo is black screen.
Here is what I've tried:
1. Pulling my current build.prop and editing it, then pushing it back with ADB. Pulling it works, but when I push it, nothing seems to happen. It says "Success" but when rebooting the device, my phone is still ****ed up. And when I pull the build.prop back again, it's the one for the Galaxy s3 and not the one I just pushed.
I read that the reason this is happening is because ADB doesn't have root permissions. Not sure if thats true though, as I obviously have rooted my phone.
2. Booting the device into recovery. For a while now, trying to boot into recovery leaves me stuck on the Pantech logo. I think this may be due to me flashing a recovery that wasn't for my device a while back. So I can't get into my recovery to factory reset it.
3. Booting into fastboot mode. The Flex is a strange creature, so there is no standard bootloader apparently so when using "adb reboot bootloader" it reboots into fastboot instead of a bootloader. Meaning on the screen is just white text saying "FAST BOOT mode" and adb disconnects, and fastboot devices sees the device now.
Trouble here is, I have the stock recovery for the Flex. But when I use Fastboot boot recovery.img or Fastboot flash recovery recovery.img or fastboot wipe data or anything in fastboot really, I get a "Not support!!" error. Which I assume means my phone is a piece of **** and can't be used with fastboot.
So now I'm at my wits end and don't know what else to do. I am dead broke and need my phone for work.
Is there anyway I can fix the build.prop or factory reset my phone?

Also, maybe there is a way to set up a VNC server of some sort to use the phone from the computer??
Hi All,
I am currently in the phone repair business. Well i buy as much as i can fix and sell on. Its all fun. I have a very nice one currently and looking to see if anyone has ideas. All i want to do is boot to recovery that is my current goal.
So phone clearly has corrupt installation, likely a flash Rom or update gone wrong. It boots to Huawei logo then reboots and that's all it does. Tried de-powering and all sorts including removing battery cable but to no luck.
There is no recovery mode
No download mode
Can get to fastboot but unable to run commands it seems due to FRP lock. I am not worried about FRP lock at this time, i only want recovery back.
Tried:-
All flash commands and all fail
Any attempt to get to receovery or download mode fails
All three buttons to force SD card boot fails
Currently trying to boot using SD card but seems i need to change boot devices from within recovery. Well it has no recovery mode so no luck there.
So it is pretty much a brick at this point and could be a write off but before I give up does anyone have any other ideas? maybe a FB command i can run with FRP lock and bootloader lock on?
Thanks
Karl
I don’t know what happened to my phone, but I booted up the phone and I get the error in the picture below. The boot loader is locked and I can’t unlock it, it says “flashing unlock is not allowed “ and I can’t access download mode or any mode except boot loader.
So is there anyway to revive my phone again? Maybe force unlock boot loader or flashing stock bios using fastboot?
Thank you for your time.

Press and hold power key to continue
You probably pressed power button which paused it from going further
That's the ugly Red safety warning, not the benign yellow one. As I understand, this is what happens if the bootloader is locked and one of the partitions fails its security check. All partitions must be completely stock when the bootloader is locked.
@runningnak3d described this somewhere, and I seem to recall it's a hard brick, or at least pretty hard. But I hope I'm wrong
