PROBLEM SOLVED! I used another pc, my usb ports were the problem! I recently got my Nexus 7 (2012), wi-fi only , I unlocked it's bootloader, installer TWRP recovery, and rooted it. For all these operations i used the N7 toolkit , because back then, I was a noob. The rooted tablet (4.2.2) worked Perfectly! But, after about 3 months, it's "volume down" button stopped working. I rebooted it, but it went in bootloader, instead of normal system. So I just select "Start" and it was in Safe Mode! OK, my "volume down" didn't work in Safe Mode (and bootloader mode) neither! And every time I reboot it, it goes to bootloader! I thought that it was a software problem confused , so I began flashing a new ROM. I didn't want to use the toolkit because everyone says that it's bad . I downloaded AndroidSDK, I re-downloaded the ADB and Fastboot drivers, and I downloaded the newer version of the bootloader (4.23, .img) . Tablet was already in bootloader and I connected it to the PC. In platform-tools folder I ran the "fastboot devices" command, and It was able to see it . So I copied the bootloader img to the same folder, and I ran "fastboot flash bootloader bootloader-grouper-4.23.img" . Then I rebooted it into bootloader again. IT WORKED! But, it didn't solve the "volume down" problem. My rooted 4.2.2 and TWRP were still on the system. Everytime I power off the tablet, and then hold the "Power" button, it goes into bootloader. It was that button issue causing that. Then I decided to take it to the service (same place where I bought iw the unloct) , but I couldn't because if they saked bootloader, non-stock recovery and the root, the wouldn't accept the warranty . I decided to download the latest 4.3 stock android, and stock recovery, flash them, and lock the bootloader. I downloaded 4.3 stock from google's official site, (nakasi-jwr66y) and I used the flash-all.bat command that came with it.
.bat command looks like this:
PATH=%PATH%;"%SYSTEMROOT%\System32"
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
ping -n 10 127.0.0.1 >nul
fastboot -w update image-nakasi-jwr66y.zip
echo Press any key to exit...
pause >nul
exit
I ran it. It successfully did the oem unlock (it was already unlocked) , all the erase commands, and flash bootloader command. But it was stuck on
"fastboot -w update image-nakasi-jwr66y.zip" . It stays steady for about 30secs , and than it says
"sending 'system' (x-kb)"
After some time it just says Data transfer failure(too manly links) ...
I tried the same process billion more times, but same error :/
I tried
-Re-downloading and installing the drivers
-Changing the usb ports, and microUSB cables,
-Restarting the pc (of course)
-Re-downloading the nakasi-jwr66y
-Downloading the twrp recovery (it successfully flashes it)
-Re-downloading the whole SDK
But it DOESN'T WORK? What should I do? Is the volume-down issue hardware or software ?
Sorry for my bad English :////////
P.S. What is the difference between "fastboot flashall" and "fastboot update" ?
Hello guys,
Sorry for my bad English
My phone just turned off even if the battery is almost full. When I turned it on its stuck in a boot loop. Sometimes it's goes to a screen where it would say process not responding. It's still on the stock ROM and recovery. I didn't try to root it or flash anything on it.
I tried some troubleshooting like flashing the firmware from the Asus website but it didn't work. Please help
Have you try flashing from Micro SD card in stock recovery?

Thank you for the reply bro. I already did and it's still not working.
To reset the phone in cases like this, one could also use fastboot.
Boot in fastboot mode by pressing VolumeUp button while switching on the phone, then connect the phone to a PC with a usb cable (you must have fastboot/adb drivers installed). You can now open a command prompt and use the commands:
Code:
fastboot erase cache
fastboot erase userdata
fastboot erase system
The second command erase all the user's data on the phone.
The last command erases the operating system and you must install the full firmware in zip format from the recovery afterward (with a microSD card or with a PC via ADB sideload).
you can install custom recovery?
I had a boot loop issue too. I could solve it by entering fastboot and trying using the defaut roms boot.img through fastboot. You can extract the boot.img from any firmware image file from the Asus site.
Code:
fastboot boot boot.img

but my case is serious, giving up
maybe you should unlock the bootloader before trying those commands
why don't u try, adb sideload option once, give it a try
i dont know what firmware my dads ze550kl is...

This may result an error if you don't flash the right file,it depends on your firmware version. I have a file that works on lolipop (twrp.).
I had the same issue, as my device was on warranty period i took it to the service centre and they said the mother board is damaged
Im facing the same problem I installed a new ROM from SD card and it was successfully done but the phone is still stuck in boot loop and unfortunately my USB debugging is disabled my bootloader is locked and my phone is not rooted and it's in stock recovery can anyone please help me

how to reinstall bootloader (recovery or twrp)??
plz help guyzz//:crying::crying:
I face the same bootloop problem with my mother's cellphone. The bootloader is locked and USB debug is disabled.
I tried to flash stock img via adb sideload, and although it succeed, after factory reset in Recovery (and pull battery several time) I could finally get into the "setup wizard" of Android system.
However, the system will go into bootloop again when the wizard goes to "wifi" setup. The phone will not go into setup wizard again unless I do a factory reset (and battery pull) again...
It seems there are some hardware failure at Wifi component (Since I already erase all \data, \cache), and this failure caused reboot of the system...
Any idea?

hey did u finnd any solution for this>???
what i messed up?
i have installed custom official cynogen14.1 rom and twrp recovery. everything was working fine.
but i messed up with bootloader. I have locked oem from fastboot mode without enabling option for oem unlocking in developer settings.
Now as my phone have custom rom and twrp installed it went into bootloop and only shows zuk logo and again restart.
What i diid till now?
i have opened backcover so that i can turn of bootloop and phone by disconecting battery.
I can enter into fastboot mode by pressing vol.+ and vol- buttons sumultaneously and connecting usb cable.
But i cannot unlock bootloader as it says unlocking bootloader not allowed. I have tried device specific commads like "fastboot -i 0x2b4c oem unlock" and "fastboot -i 0x2b4c oem unlock-go" but nothing works.
i have stock recovery image but cannot flash while bootloader is locked.
i can enter into adb sideload by following method:
by loading stock recovery by typing "fastboot boot recovery.img" (this does not work with twrp as it says signature varification failed)
and then selecting apply update >> selecting apply fron adb
this much i can do does anyone knows how to recover from such a state.
please help me or my phone will be a waste.
is there any way to install stock recovery i think phone will boot properly if i managed to install stock recovery.
I messed up.
Flashed LineageOS 14.1,
Forgot to flash gaaps,
Afterward, for some reason could not enter TWRP and in 'Developers Options ' there was no option to OEM Unlock so I could not do 'fastboot flash recovery recovery.img' to regain TWRP.
tried to use the 'dload' method to return to stock 6.0.
message said uptade successful.
The phone now does not boot, does not enter erecovery, does not enter the updater (Power Button+Vol. Up+Vol. Down)
Only thing it does is enter fastboot (it says PHONE Unlocked and FRP Lock).
Can you help me?
Edit 1 : In fastboot mode only commands with fastboot work, no adb.
Because it is a Huawei the command 'fastboot oem unlock' does not work.
Edit 2 :Tried to 'fastboot flash system sistem.img' to flash the system.img from the update.app of stock android, unfortunately with the phone OEM Locked there is very little I can do with fastboot.
If anyone can direct me to a fastboot friendly update.zip that has the android-info.txt that seems to be required for for flashing I would apreciate it. (I have read that you can flash google-signed update.zip's while having OEM Lock)
Edit 3 : Looking through XDA I have found user with a similar issue to mine that have been able to enter recovery update after either letting the batery run dry or using fastboot to erase/format userdata and cache, the result for me is again 'FAILED (remote: Command not allowed)'.
Will be sending the P9 to Huawei and see what they can do with this.
Edit 4 : Huawei replaced the board and the battery (apparently it died during the trip to the repair center) they accepted the warranty despite the fact the phone was stuck on the warning screen that said the phone was unlocked.
To summarize, I have a Moto G5 Plus, with locked bootloader and I decided to update a ROM STOCK and made a simple mistake by forgetting the OEM unlock option in advance in the configuration menu. An error occurred on the way and tried to return to the stock. Now, when the phone boots up, it enters the boot loader (which is locked) and displays a startup error message that states that you must use the Software Repair Wizard.
trying to enter the recovery gives a code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG "bootmode" configured as fastboot
failed to validate boot image
ERROR: Failed to pass validation, backup to fastboot
Boot up failed
Is there a known solution or force a recovery to work?
Thanks to all
Hello;
I found the solution, download the latest firmware from your cell phone, download it just unzip the zip and look for the files: gpt.bin and bootloader.img, those 2 ctrl + c and files go to the folder where they downloaded ADB tools and paste the files there , then execute the steps to open command window here and execute the following:
fastboot flash partitiongpt.bin
fastboot bootloader bootloader.img
fastboot reboot-bootloader
and it is ready to install the downloaded rom.
