I've been running Cyanogenmod 9 for a couple of months, but decided to restore to stock so I can try out ICS and the new version of sense. I tried this a while ago but got stuck when when phone wasn't recognised via USB when connected to my laptop. Fastboot would change to Fastboot USB when plugged in, but the phone wasn't picked up. However, on this occasion I was able to restore Cyanogenmod without problems.
I tried this again yesterday with the same result regarding the USB connection, but when I restored Cyanogenmod it now just hangs on the boot screen and won't go further. Prior to this, when I ran the restore function in Clockworkmod, the phone would hang on the HTC splash screen with the beats audio logo on it. I did manage to get the phone to boot into recovery, but rather than the usual menu option I had a message something like "checking SD card..." and then nothing.
I am not sure where to go from here. The only thing I am wondering is if I tried to do this with the battery being too low, and the installation has failed because of this. I do want to go back to the stock OS, but not sure how to go about resolving the USB issue.
UPDATE
Partially solved the problem, in that I've managed to reinstall the cyanogenmod. Still stuck with lack of USB connectivity though.
Wrong section.....
Do you have the Fastboot files all in the same folder and do you have the HTC Sync drivers installed? You need that set up correctly to get a fastboot USB connection.
My suggestion is to simply "fastboot oem lock"
Then flash corresponding RUU to your current HBOOT. You can find out which RUU you need by typing "fastboot getvar version-main"
Hi:
The problem is the next: My HOX was bricked, the LCD display never turns on, i always have a blank screen. My firmware is 3.14.707.24 and i try to use the RUU for my CID_044 to unbrick my device like the user mr.dj26: http://forum.xda-developers.com/showthread.php?t=1859339&page=2. But after i put the unclock code (hdev) to flash the boot.img and recovery.img, my device is totally bricked.
I always have blank screen, but the device can restart and light the bottom buttons, but is like not have any rom. The device is only recognized for my windows when i put the device in bootloader, and when i use fastboot devices, he recognize the device, but when i try to flash any file use getvar command and others, he always say me: FAILED (command write failed (Unknown error)).
Before have this problem, i had blank screen but could hear the sound of the ROM starting and access to the device using adb and fastboot. Using the RUU always say that the battery still under 30%, i put 4 hours to charge and always the led is red. Connect the device after that and always have the same ERRORS. I drain the battery reboting a lot of times and after that i charge the device. After a 2 or 3 three hours the led turns green, but when i reconnect the device i have the same ERRORS.
My HOX is totally bricked or i could do something else to recover the fastboot and ADB connection to flash the ROM using RUU?
PS: I attach pictures of the fastboot errors and the device manager screens of my pc.
My guess is no you can't do much more then this, if you can't flash a recovery or boot.img the game is pretty much over..... sadly enough.

Thanks for your answer. Sad but is a answer. In this case i need a motherboard to fix all the problems (blank screen and no rom):crying:
Good luck on getting it fixed mate !
All the best

I recently replaced my Cracked Screen on a Verizon m8. I was on a custom rom with twrp installed. After the initial boot, I was having problems with a speaker and went to try to boot to the bootloader to do a RUU, when I noticed that I can no longer access the bootloader screen. It was then when I noticed that not even my computer was recognizing the phone no more. It's as if the phone won't debug no more. I can still access my TWRP by rebooting straight to recovery thru a app or the apm it has on the custom rom im using. I've tried to flash other roms with no success to get access to these two things. I was wondering if anyone had a stock twrp of Verizon version. As for all my twrp are from custom roms. Or if anyone has had this problem before or if any suggestions im open to anything to try and get to the bootloader screen. It also doesn't even boot the two or 3 second boot up screen until you get to the roms boot up screen. It also doesn't goto the bootloader screeen when it try's to access the bootloader. Even when booting straight to recovery stays black until twrp actually shows up. So it's as if bootloader is completely being bypassed. You cant use the volume keys to access the recovery cause everything is blank. Although on first attempt to access bootloader screen when I was stuck there in black. I had to figit the keys a bunch of times to reboot, hoping that I didn't activated something in that screen that caused the phone not to debug. Any suggestions is more then welcome and if someone has a stock twrp of recent stock rom 4.605.9 I believe it is would be more then great. Cant find one other then in zip or exe version. Hoping maybe that might reactivate those two things. Thanks for taking the time to read my problem.
Debugging or adb works within OS, and its not a mode in itself. I think you mean you can't access bootloader-fastboot mode.

You mean stock recovery. TWRP is a specific custom recovery, therefore always a custom one.
I don't think stock recovery will change anything. Bootloader is on a completely different partition.
Its odd that you can't access bootloader. It must still abe intact, otherwise the phone would not work at all.
Did you try (in OS): adb reboot-bootloader
Are you s-off or s-on?
The phone is S off. I was able to get the phone to USB debug. I took it out of the shell and plugged in the USB cord and it debug instantly . So I'm guessing with that I had to damage something when I either took the phone out of the shell originally or when I replaced the screen. Cause you literally have to take every piece of the phone off and then reasamble the phone from scratch. Once i put the phone back in shell, i couldnt get it to usb debug no more. But I still can't access the bootlader, nor is the first boot screen on power up before the main boot up screen starts. Also has no display if I reboot to recovery using a app from the phone. You don't see the screen where the red text would show up saying rebooting to recovery, display starts when it begins to show twrp on display. But when I had the shell off, and was able to access USB debug, I was able to use adb commands from my computer from fastboot mode , but phone had no display. Was able to run a RUU, was able to use adb to reboot to boot loader, then was able to fastboot get varall command. Even flashed a twrp recovery install in fastboot under command prompt . So that tells me that the boot loader is operational. That it has to be some sort of power failure in booting that nots powering the display on initial boot for 2 to 3 seconds , no power on bootliader display, no power rebooting to boot loader or rebooting to recovery until it boots recovery. Any ideas what would cause this failure of power of display during boot loader processes? By the way , have twrp 2.87 . Its a Verizon build, but I'm on a T-Mobile sim.
I've installed live boot and attached a log. If anyone can help or maybe know why this might happen. Believe there is two boots, each with a separate power. Main boot is the initial power up last two or three seconds, and then system boot.. Believe main boot is sending power off display and then power on display on system boot.
Hello,
I seem to have really messed up my G3 and after days of research I have not been able to get anywhere with it. I've read posts of people having similar issues, but their solutions do not seem to work for me.
What I tried to do is flash the ROM, starting with TWRP. After installing TWRP and rebooting I was getting the "no command" message on the screen. I believe (this was days ago), I used ADB to remove laf and reboot the phone (for some reason I could not back it up). The phone rebooted in fastboot and it has been downhill from there.
No download mode. When normally started the phone just hangs on the LG logo. Vol- and power gets me to the "Factory data reset", but if I do that, it flashes "erasing" for a second and it goes back to the LG logo screen.
I can get to fastboot, however, any command that I enter in CMD or Linux terminal just shows up on the phone's screen and it does not do anything. Fastboot devices shows the device as "????????" in Linux and as "?" in Windows. I have tried multiple drivers for Windows.
I tried BoardDiag (3 or 4 different versions running as admin) and shorting the pins, but any time I try to run the checks, I get an error - "No response from device" or "Device was not found in dload trying flash programmer"
I also tried SmartBootDiag, but once it detects the phone, it does its checks and it disconnects the device, without giving me an option to flash anything. Looking at the logs, it does not find any anti-rollback issues.
Any suggestions would be greatly appreciated as I am not sure what else to try.......
Thank you.
Anyone??
Hello @All,
I bought myself a new toy: a bricked Nexus 5x. The only thing I can do is enter the bootloader mode. Otherwise the phone is showing the Google logo.
In bootloader mode the last two lines are "Secure Boot - Enabled" and "Device State - Locked". The "fastboot devices" states that the device is present.
I can neither access any recovery nor install one (because bootloader locked). The device isn't rooted. Parallel to posting this I am searching the depths of the web. Of course without a solution.
Can I do anything else?
hmm, did you try going into the recovery and resseting it, if that didnt work go on your computer, go to bootloader mode, and on your computer try typing: fastboot flashing unlock or fastboot oem unlock, if none of those work, then try reflashing the firmware trough recovery or fastboot, here is the rom for adb sideload trough recovery...
here is a direct download cuz it wouldnt post the zip https://dl.google.com/dl/android/aosp//bullhead-ota-mhc19q-8fe67a2b.zip
I can't access the recovery, but I'll try fastboot again. "fastboot flashing unlock" and "fastboot oem unlock" don't work. I get a " FAILED (remote: 'oem unlock is not allowed')" message.
ok, try this, go in fastboot, and run this command, fastboot flash boot N2G47Z_4Cores.img with the img that i send you, if it works, then see if iit boots up!
it doesnt wanna send it, heres a link to download it https://www.dropbox.com/s/tm7qt98r6d7q2a6/N2G47Z_4Cores.img?dl=0
I tried
Code:
$ fastboot flash boot N2G47Z_4Cores.img
and the answer was
Code:
Sending 'boot' (12045 KB) OKAY [ 0.464s]
Writing 'boot' FAILED (remote: 'device is locked. Cannot flash images')
fastboot: error: Command failed
...
But thanks for your effort to help me

hey is there a way you can send me a video of what happens when it boots up and when you try to enter recovery, maybe i can still help.
if you cant here send it to my mail [email protected] , this is my mail since 2016 and zombie was mostly for minecraft . but then i was young, so yeah.
I can only describe it for you...
When I try to boot into recovery it happens the same as booting the system. The Google sign appears with a short buzz of the vibration motor, then disappears after 16 seconds, and a second later the same again. A classical boot loop. I can only access the bootloader mode. When I try to boot from there, the same happens. The "system state" is locked, and Secure Boot is enabled.
I can power off the device from the bootloader, then it stays off.
Is there any hope to bring it to life again, or is it a brick forever?

well it looks like a problem with either the ram, vibrator, or the partitions, sadly this happened with old nexus devices, so its a brick forever sadly. but if you want you can sell it online for parts.
Ok then, I hope I can sell the brick. Thank you again for your help, @NikolaTechGuy !
But there's one last hope: This thread, shown to me directly under this answer ("Similar threads") that I'm currently writing. One last try...

Sorry if this is too late but are you sure you can't do anything with the phone?
To enter Bootloader Mode press and hold Vol Down + Power. You will automatically enter Fastboot Mode. You will see the settings of 'Secure boot' and 'Device State'
Use Vol up and Vol Down to scroll through menu and the Power button to select an option:
Start
Restart bootloader
Recovery Mode
Power Off
If you select Recovery Mode, wait until you see the 'Robot lying down' image and "No command" text appear on screen. Now hold Power button and briefly press the Vol up button. The 'Android Recovery' screen should now appear.
To enter LG 'Download Mode':
Power Off your phone.
Now press the Vol. Up button and hold it
Now Plug your phone into your computer using a USB cable
After a few seconds 'download mode' should appear on your phone screen, followed by a 'Firmware Update' screen.
If it doesn't enter LG Downoad Mode then check in your Windows Device Manager under COM/PORTS. See if you have connected in Qualcomm 9008 EDL (Emergency Download ) Mode. The connection will appear as Qualcomm HS-USB QDLoader 9008. You might have to download the Qualcomm driver for this to work.
If you can get into Recovery Mode or EDL mode you still have options! It depends how much time and effort you want to spend on a 7 year old phone with no sd card option.
You can become 'obsessed' like me, and buy a hot air gun solder rework station to try and reflow the solder under the MSM8992 chip to fix the 'bootloop of death'! NOTE: I have tried it on 3 bricked Nexus 5X and only got a temporary success on one phone - the other two I did a very good job of frying the chip! Mind you I now have alot of spare parts!
I took the Nexus to a repairman who calls himself "Handy-Doc". He told me it was the hardware. He couldn't install anything as well as me. But replacing the motherboard could help. So I ordered a motherboard on AliExpress. This is my last try!

You will have to keep us updated. I looked at those motherboards but wasn't sure about them. What version of Android is installed? Do they come with a new IMEI or are they blank? etc. Taking a 5X apart is very straightforward with a couple of simple phone tools. There are plenty of Youtube videos that show you how to do it - it might save you having to pay "handy-Doc"!
No, it doesn't work. I can plugin the phone when it's in "Download Mode" but nothing more happens. After a few seconds the phone tries to boot again. The "Handy Doc" man gave me back the phone without asking for payment.
The motherboard is on its way from China to Germany. This can take several weeks.
Hi
I am sorry if I am posting this at the wrong place.
I bricked my Nexus 5x device flashing DivestOS on it.
I flashed two different LineagOS on this device successfully in the past and the genuine Android when I was rolling it back. It always worked, but not this time.
Trying to roll it back to genuine Android, there were errors that several ".img" was missing in the archive.
I tried to chat with Android developers on Matrix chat and also reported this problem here, on DivestOS forum, but they blame hardware and/or user mistake.
I took it farther to sort the device problem and made it unresponsive, the screen is black and it does not react to anything at all now.
All I needed to know if there is ANY way to bring this device back to life.
I found some "LGFlashTool_2.0.1.6" on one of the old forumes of (2016), but I did not try it, I believe it will not work, and wanted to know from Android developer's oppinion before I try anything else.
Thank you
---Update:
I opened it, unplugged and re-plugged the battery.
Was able to boot it into the fastboot menu.
1. secure boot - enabled
2. device state - unlocked
-Tried to flash the genuine Android (I did it several times and I know it works)
No success!
Please see the terminal screenshot attached for errors.
If you can get into fastboot have you tried flashing TWRP and getting into it again? Then try flashing a lineageOS that you know works.

Thanks for reply =).
This is a goot point.
I'll try and post the result here.
Now, not always I can boot it into fastboot menu, sometimes it's totally un-resposive, does not show any sights of life, it can be the battery charge problem (battery was not bad though).

Yea, looking at the log everything appears to be okay until that last line. Did you use flash-all.bat from the factory image bullhead-opm7.181205.001-factory-5f189d84.zip?
