Hi all,
Just wondering if anyone might be able to lend a hand... Im trying to flash back my Pixel C back to stock (currently running TWRP and build from [ROM][UNOFFICIAL][LineageOS]18.
For some reason, when running the flash-all script or manually flashing the Booloader img, it comes back with "writing 'bootloader' failed (remote 'unsupported command')".
The tablet still boots into the Lineage OS (at least its not a brick... yet..) but really like to try and get it back to stock if I can..
if it helps..

When running the flash-all bat file:
If you have no working recovery there is no way to fix this problem (at the moment).
Instead, if you have a working recovery, you could use the following fix from adb shell:

Thanks bernardomarx! That seemed to have done the trick!!
Yeah - Luckily TWRP recovery was still accessable, typed in the command within TWRP Terminal. And followed the post you linked to
Essentially after doing the fwtool command in a cmd window:
>fastboot erase userdata
>fastboot erase boot
>fastboot erase cache
>fastboot erase recovery
>fastboot erase system
Flashed the bootloader:
fastboot flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
I then had to extract the img zip file and manually flash each img file:
>fastboot flash system system.img
>fastboot flash boot boot.img
>fastboot flash recovery recovery.img
>fastboot flash cache cache.img
>fastboot flash vendor vendor.img
Many thanks for entering the details of how you recovered your Pixel C. I had the same problem when un-installing TWRP. I did performed the same steps as you, and the tablet is back up and running!
Many thanks for documenting it here!

A friend of mine has a CID 044 and still got ICS since his Bootloader is already unlocked and he doesn't get OTAs
So, he tried to install the Jelly bean firmware from here: http://forum.xda-developers.com/showthread.php?t=1957376
and while writing the commands he ran into a problem, thats what he said happened:
After he wrote the first command [fastboot oem rebootRUU] the phone rebooted into the HTC logo and got stuck there, so he rebooted it again and it rebooted as usual
Then he got it back to fastboot USB, wrote the second command and this is what he got:

Anyone knows whats wrong?
You can't run that command in fastboot mode. When he ran 'fastboot oem rebootRUU' the phone should have rebooted to a black screen with the HTC logo - this is normal. While on that screen run the second command to flash the zip (he'll probably have to run it twice because it usually throws an error the first time round).

Any chance you know whats the problem is?
Thanks alot
1. Which version of the firmware are you trying to flash?
2. Did you relock your bootloader before starting? If not, boot back into fastboot, run 'fastboot oem lock' and then try again.

1. copyed from where i downloaded
x.xx.707.x - Asia WWE (World Wide English)
cidnum: HTC__044
Download:
firmware.zip with hboot 1.36
2. I didnt relock my bootloader before starting,
Now it finnaly worked, but it stuck on the black screen with the htc logo, and it added like a green loading bar that showed that it had finished loading but still stuck on this screen.
Should I wait for something to happend or reboot manually?
Reboot manually (use 'fastboot reboot-bootloader' to get back into the bootloader and unlock it again)
i am tired to flash this rom

ok when you have downloaded the file, put it in the same folder as ADB and fastboot files and rename it to RUU for ease
you will need to use the HTC_fastboot.exe to flash it, normal fastboot wont flash Lollipop RUU's, get the htc one from here and put in the same folder as your RUU.zip and other adb and fastboot files: https://www.androidfilehost.com/?fid=95916177934550031
then do htese commands:
fastboot oem rebootRUU (phone screen should go black with sliver HTC logo)
htc_fastboot flash zip RUU.zip (YOU MUST USE THE HTC_FASTBOOT to flash the zip, the normal fastboot wont work, now leave it alone to do its thing, takes about 10 mins, no need to issue this command twice as its automatic with the htc_fastboot)
now make sure when its finished and you have a command prompt and that it says successful at the end and OKAY
if so then type fastboot reboot-bootloader
now fastboot reboot

Hi guys, i really need help here.
i wanted to flash and install TWRP.img on my redmi note 8 today, but i accidentally used the cmd command fastboot flash boot TWRP.img .
my phone then only boots to TWRP instead of my usual MIUI. so i tried flashing the whole note 8 rom using MiFlashTool. However, there is a error (error:Mismatching image and device), and now my phone only shows me that "the system has been destroyed".
when i tried to flash another boot.img to the phone, it shows "FAILED (command write failed (unknown error))"

I don't know if you can enter to fastboot mode (power + vol down button). If you can, you can try fastboot flash recovery TWRP.img and search for boot.img at Google I think....
---------- Post added at 23:41 ---------- Previous post was at 23:36 ----------
I think this may helps: https://c.mi.com/thread-2542493-1-0.html
I think that the key is to get boot.img (miui or custom rom) from installation zip and flash it again to the phone via fastboot
If you could boot into twrp, then try to flash the boot image of your firmware from twrp. First extract the boot image and place it in your SD card, then in twrp select flash image and flash it to the boot partition, might work.
I got the same message even when trying to boot into recovery, even flashing the recovery again didn't work, so I downloaded The stock rom uncompressed and flashed each img manually with fastboot

Hello Community!

But now I get "Message THE SYSTEM hat been destroyed".
MI UNLOCK SAYs UNLOCK no Nessesary. Is unlocked.
I COULD NOT BOOT INTO TWRP after Flashing TWRP.IMG

Lately, after using this separate phone(Vivo V7+) for 2 years, I've been trying to root it.
The basic drill I found to root this phone is,
- Unlock bootloader
- Install TWRP
- Root it using Magisk/SuperSU
I've tried most of the methods mentioned online to unlock the bootloader,
While trying to unlock it using vivo fastboot, An error occurs.
Command: fastboot bbk unlock_vivo
Result: FAILED (remote: unlock fail.)
Another command: fastboot oem unlock
Result: FAILED (remote: unknown command or device is lock)
When rebooting device into fastboot using: adb reboot-bootloader the developer option, oem unlock & usb debugging all was turned all.

I am facing the same issue.
V7+ bootloader unlock failed adb fastboot
Please help me to unlock bootloader
I have same issue to unlock the bootloader for vivo
I typed the methods, and it's not working
People said for new phones use this command: fastboot bbk vivo_bsp unlock_vivo
But I tried that to my new vivo phone and it's not working also
I'm thinking that people who failed need unlocking bootloader tools or download firmware of the vivo and remove bootloader (Make sure the stock firmware must have higher version, and your phone not updated)
Note: people have to downgrade to low version of vivo if they want the cmd method(if still not working)
If you are facing the bootloader issue in you device thenclick here to take guide about it because some months ago I also faced this issue and this platform helped me on that time.
my phone only restarting with message ΄΄this phone is unlocked will continue to boot in 5 seconds''''...But i type fast the command (fastboot reboot bootloader) so i get into download mode...now i am trying to flash twrp but nothing happening....i use cmd from this folder...the phone is stucked..cant start..i dont know what happened...i just tryed to put new twrp because i want install new rom....thanks all guys.....

'No such partition' means there exist no such partition 'recovery'!!!!!!
don't use exclamation marks!!!!!!
RTFM!!!!!!
what i must do bro
I recommend to read the instructions.
first, set your windows explorer view so you can see file name suffix. unbelievable you didn't do this yet. you can't even differ .img from .zip
this is just common instructions for devices with recovery ramdisk in boot partition. (no guarantee it is suitable for your device)
Code:
fastboot boot twrp.img
adb push twrp-installer.zip /tmp
adb shell twrp install /tmp/twrp-installer.zip
i need to join in powershell for the adb commands ?
cmd.exe is prefered.
what i do wrong...can we just make a reset the phone and start from the begine?
https://github.com/TeamWin/android_device_razer_cheryl about this ? can we make something ?
you are typing invalid commands without any sense.
the first command flashed twrp into boot partition (boot_b) successfully.
now set slot B active slot and reboot. this will bring you in TWRP recovery.
Code:
fastboot --set-active=b
fastboot reboot
once you are in TWRP restore the boot partition from adb shell. do not type commands you don't fully understand!
Code:
adb devices
adb shell
# dd if=/dev/block/bootdevice/by-name/boot_a of=/dev/block/bootdevice/by-name/boot_b
# exit
you have now repaired your boot partition.
now in TWRP proceed with installing TWRP. this will install TWRP into both slots.
Code:
adb push twrp-installer-3.6.0_9-0-cheryl.zip /tmp
adb shell twrp install /tmp/twrp-installer-3.6.0_9-0-cheryl.zip
Τhe device still does not enter into twrp and restarting all the time.this is the all problem,i cant untarstand why the factory twrp disappeared
you probably did not check current slot beforehand, maybe flashed TWRP into wrong slot.
get stock boot.img according to the current ROM and flash into both slots. if phone is working, start from scratch.
what must type to check if this happened ? btw thanks so much for your help.
according to instructions one must boot up android and from adb shell getprop ro.boot.slot_suffix - but it's too late now. you can try these commands from fastboot
Code:
fastboot getvar current-slot
fastboot getvar slot-bootable
fastboot getvar slot-successful
do you have boot.img?
C:\Users\Main User\Desktop\mobrom\platform-tools>adb shell getprop ro.boot.slot_suffix
* daemon not running; starting now at tcp:5037
* daemon started successfully
adb.exe: no devices/emulators found
i dont have boot.img
as stated adb works only in fully booted android (with usb-debugging enabled) or in TWRP recovery.
if you don't have any boot.img congratulations to your first brick.
search in the thread if someone has shared.

you need matching boot.img according to the current ROM. you can check ROM buildno from fastboot.

you can search for ROM on mirrors.lolinet.com and extract zip file.
