I tried to flash stock kdz with LG Flash Tool 2 days ago and process was stopped in the middle of flashing so I had to exit program and to pull my battery off. And then when I tried to turn phone on again it wouldn't boot but it showed only something about fastboot and when I'm trying to flash something with it I get unknown error.
This is what it says on screen:
fastboot int()
loading keystore failed status 5
Usb init ept @ 0x....
udc_start()
--reset---
--portchange---
fastboot: processing commands
Phone wasn't rooted and bootloader was locked, I can't access download mode anymore, neither anything else cause no matter what combination of keys I use it only boot into this.
So what are my options for this?

[Q]Fastboot mode works-> many comands get FAILED-> recovery not working-battery down?
hi,
the thing is i can boot my honor only into fastboot mode and i'm able to flash files. but on many cmds/options like erase, format,getvar,-w... i get the error message "FAILED (remote: command not allowed)" -the phone is unlocked, do i get the error because maybe usb debugging is disabled?
the other thing is when flash recovery and reboot the screen turns black and than white and nothing happens. not booting into recovery or system. could this be because battery is empty/not loading anymore? (tried fastboot loading script but getvar cmd gets FAILED error, so i can't view my battery charge)
if you have any idea, just feel free to tell
Hi, I have the same problem.
After y try to update 5.1.1 beta, my phone is dead...
Please can anybody help us?
Hi everyone I first want to sincerely thank everyone that will answer to try to help me solve these problems with my nexus.
So the other day my nexus suddenly decided to stop being awesome and it started to be a pain in the ass instead.
When I turn it on it just keeps loading the booting animation of android 6 marshmallowand it never turn on. I identified this problem as a "bootloop" and i tried solving it anyway but it's being really hard and i'm almost getting no results.
I first tried with going into recovery mode. from the fastboot the recovery mode won't start, pops out a died android with a red triangle on it. Pressing volume up and power from that screen got me to another menu. I tried wiping the cache and wipe all the datas/ factory resets but no results. the crappy marshmallow animation goes on till forever.
On the screen that follow the dead android appears the error: E: failed to mount /cache (Invalid argument).
After that i tried with the famous sdk tools.
I am able to unlock the bootloader with the command [fastboot oem unlock]. however after unlocking it, if I turn the phone off and on again it auto lock itself.
i tried to flash a recovery image with the command [fastboot flash recovery recovery.img] but it won't flash. I unlock the device first, and then i try to flash the images. it says ok after the sending but on the writing says FAILED <remote: flash write failure>
same things happen flashing anything else (android factory images etc.)
I can't use adb, i d need to put the usb debugging mode from the developer options but since I coulnd't turn it on I don't know how to turn this option on.
So i discovered existed a "download mode"
Apparently for the nexus5 you have to push volume up and then connect it to the usb to enter in it. I tried many times and it just don't go to download mode (is this the correct procedure??)
I installed the last google divers, no results.
I really don't know what to do, do you guys have any ideas about how to save it?
phone details:
hammerhead d821(E) 32GB
hw version- rev 11
bootloader version: hhz12k
Cheers

I think your emmc chip has gone bad and that is why you are getting locked bootloader everytime you reboot the phone as it is not able to hold any memory.
I suggest RMA if its in warranty

OK so ur ennc chip is NOT dead, that little Android with the triangle is stock recovery, which u can do nothing with, ur going to need a PC, preferably running ubuntu or some other form of Linux with adb and fastboot installed, i cam help with that too if u need it, once u get that settled what u need to do is this, download TWRP for ur hammerhead and rename it recovery.img, place it in a folder u have access to. Open a terminal and connect ur nexus to the pc with USB cable, and boot into bootloader. Then type this into the terminal:
cd (folder with recovery.img in it)
fastboot reboot bootloader (this should boot u back into bootloader if ur device is connected right)
fastboot flash recovery recovery.img
fastboot reboot recovery
This will boot u to TWRP in which u can perform a factory reset, if this doesn't work and ur still in a bootloop, download ur fav rom and gaps and flash it, this will take care of everything
And there is no download mode on the nexus that would be bootloader mode, so let me get this right, what system are u on, and did u try manually formatting with ADB? What happens when u do, I would force format cache, system, boot, and userdata and then flash recovery, that might work

Hi,
I Got some problems with my Nexus 5 last days. First it was the power button problem and it was restarting all the time. I cleaned and it seems ok now.
But NOW my android is not restarting. I don't know if it was due so many restarts during the last few days ... The point is : Or it stocks at the '' GOOGLE '' screen, or it goes to the last part with some colorful stuffs '' gifs loading '' FOREVER.
I Don't have the USB Debugging mode ON so I can't do anything from ADB using my computer.
I Cant access recovery mode ( ALL STOCK SOFTWARE ). When i open the recovery mode it just shows the android with red triangle and NO OPTIONS. Neither Reset and other options that should be there.
I really don't now how to proceed from now.
Any tips?
Thanks !
When you enter recovery, you are suppose to see th dead android with the red triangle. When you see this, hold the power button and press volume up to enter recovery.
That's what i tried to say , sorry. Even doing that nothing happens. None options are shown.
Try reflashing recovery.img file
Hi,
After sometime I'm able to access the recovery mode. But my device are still dead.
Now ,when I open recovery mode it shows right this at the first screen
'' Supported API: 3
E: failed to mount /cache ( Invalid Argument) "
I've already tried to wipe cache/FR and it shows just a lot of problems in creating/wiping partitions.
I tried as well to run the flash-all.bat from the latest android version files from android website but nothing worked.
Any tips to proceed?
Trying to flash using cmd, file by file i got erros like that
'' erasing cache/userdata/system(all those)
FAILED ( remote: failed to erase partition)
Finished. Total time 0.2s ''
For all files from bootloader.img to syustem/recovery/radio/userdata/cache
edit : I've use '' fastboot oem unlock '' , but didn't worked as well.
When you unlock the bootloader, does the bootloader relock itself when the phone reboots?
Yes, after I reset the bootloader relock itself !
Since the bootloader relocks itself after a reboot, the motherboard memory is damaged; therefore, you will need to replace the motherboard.
Hi,
Today I tried updating my phone by flashing the factory images with flashall.bat. After that I relocked the bootloader with the fastboot command in cmd but then my device started bootlooping and the bootloader displayed ''Error: Load ImageAndAuth Failed ''. I tried booting on Boot slot B and doing the same procedure to flash the factory image and not my phone is bricked, it is no longer being recognized by my PC and there is still the same error message being displayed on the bootloader. Can't execute any fastboot commands since it is not recognized, fastboot says ''waiting for device''. HELP
Edit: Boot loader now displays '' Error: Slot Unbootable: Load Error.
FIXED
I fixed it by completely draining the battery by maintaining the power button held with a rubberband. Then when the little red light was flashing I plugged the phone in the pc and after a few seconds the bootloader showed up and my phone was detected.
Optional: When flashing stock with flash-all.bat I was always betting ''archive does not contain xxxx'' and then my phone wouldn't boot. Ultimately I extracted the 20+ files in the zip image file and manually flashed all img files with fastboot, then I relocked the bootloader and now everything is working fine !
Good morning!
While attempting to flash a stock MIUI 10 ROM into my Xiaomi Redmi Note 7, to downgrade back to Android 9.0 due to some app compatilibty issue, I messed up big time and my phone is now stuck in a loop where the screen turns on, nothing shows up, then it restarts, going off for a few seconds and turning on again.
Power Button + Volume UP successfully brings me to the stock recovery 3.0 from xiaomi.
Power Button + Volume DOWN fails to bring me to the fastboot mode.
If I select the Connect with MIAssistant in the recovery the phone will show up as "sideloaded" after using the command adb devices, but the MIPCSuite app does not see it and the command adb restart bootloader also fails to bring up the fastboot mode, it just gets stuck in the loop again.
More context on what went wrong and caused this: I followed an online tutorial to flash a rom using the MIFlash app, so I unlocked the bootloader and tried to flash the rom usin xiaomi's tool. I got a failed to check sparse crc error code and it went downhill from there when I tried to fix things reading multiple threads on the issue. I tried deleting some lines from the flash_all.bat file and tried to flash it again but then the flashing process went seemingly forever so I aborted the operation and now this loop happens. I tried a few more times but with no success.
The first time I tried to use the tool I used the clean all and lock option so I'm not certain if the miflash tool locked the bootloader regardless of the outcome of the flashing attempt.
Is there hope? Can I fix this phone if I only have access to stock recovery and nothing else (although it shows up in adb devices but can't get into fastbootmode) ?
Thanks a lot to anyone who took the time to read and possibly help.
Both ADB and Fastboot are Android-side launched by device's bootloader. If you can't enter Fastboot mode then my guess is there is something is wrong with curently installed Android.
BTW: If you lock device's bootloader then bootloader attempts to load device's Stock ROM.

I see.
What can I do to try to fix this issue?
I finally managed to fix it through the Emergency Download Mode (EDL). It requires Xiaomi Authentication which I bypassed using this guide: https://www.droidwin.com/fix-mi-account-authorization-unbrick-xiaomi-edl-mode/
With that setup I flashed a stock rom using the MiFlash tool.
