[Q] How to flash an hboot with fastboot/adb

Clockworkmod recovery doesn't work(only get a blank screen after I make my selection), and my phone wont boot. I'm trying to flash a rom via fastboot or adb.
I installed fastboot and adb using this guide:
fastboot adb guide
I downloaded htc sync to install the drivers.
I'm trying to follow this guide for flashing a new rom
xda flashing guide
when i try "fastboot -w" the command prompt returns "erasing 'userdata'... FAILED <remote: not allowed>"
it seems the sollution for this is posted here. but i don't know how to flash an hboot. Can anyone point me in the right direction? I've been searching and all i could find was fastboot commander, but when I try to flash a new Hboot or my recovery image it returns "flash FAILURE"

In clockwork use the trackball to select items, not the power button.
To use most fastboot commands you need an unlocked bootloader, or the engineering bootloader. To chanhe your bootloader you need to be s-off, or do an entire ruu.

Wasn't using the trackball. This is embarrassing. Thanks for all the helpful info, you're awesome.

=X
wow this is funny, but sadly it helped me also

In case you'd still like to know how to do it via fastboot, here are some steps:
Place the .zip in the same directory as the adb and fastboot executables
Double check the md5 of the .zip before proceeding to prevent bricking the device
Run the following commands in command prompt:
fastboot devices //Verify that the device is detected
fastboot erase cache //Not sure if this is completely necessary, but the guide I followed included it as a step
fastboot oem rebootRUU //Boot into RUU, which lets you flash HBOOT, radio, etc.
fastboot flash zip [zipname.zip] //Replace zipname.zip with the actual name of the file you are flashing
fastboot reboot-bootloader //The guide I pulled this info from didn't specifically say that you should reboot to bootloader rather than to Android, but I have seen others mention that you should always reboot to the bootloader first after flashing an HBOOT or radio. I would do this just in case

thehiggins you saved the day

Thanks You
Didn't know I had to be in RUU. When do I need to be in RUU, when flashing the boot or any boot related img/zip ?

[Q] Bricked Galaxy Nexus GSM 4.1.1

I was trying to update my Galaxy Nexus GSM 4.1.1 but I did something wrong and now its not booting.
The bootloader was unlocked using fastboot. Then I am not sure what command I used, it was either "fastboot boot boot.img" or "fastboot flash boot boot.img" and now the phone won't start. Any suggestions?

As you are describing adb commands I assume you know at least half the stuff you need to know for manual flashing. If you used the factory image, aka "takju-jop40c-factory-1a47c890.tgz" and unpacked the contents, you need to follow the steps inside "flash-all.sh" - which are as follows:
While in bootloader, type:
Code:
fastboot flash bootloader bootloader-maguro-primelc03.img
fastboot reboot-bootloader
fastboot flash radio radio-maguro-i9250xxlh1.img
fastboot reboot-bootloader
fastboot -w update image-takju-jop40c.zip
This, of course, only applies for the respective update above.

Solution
Thank you for the help but I was able to figure it out after some googling.
I wrote a short guide that will help anyone else that has a problem.

Flashing to stock Android NPD90G from TWRP error: "remote: unsupported command"

Flashing to stock Android NPD90G from TWRP error: "remote: unsupported command"
Fixed flashing error "remote: unsupported command" when flashing a Pixel C back to stock
I used TWRP and SuperSU to root and modify the buildprops to enable and get an early look at the windowing in Android N beta on my Pixel C release 5 ahead of time.
When Release 5 NPD90G was available I decided to flash back to stock from Developer Preview 4 NPD56N rooted with SuperSU and flashed with TWRP. I like root - I run Ubuntu and Win 7. I don't mind running a rooted device if it doesn't have all my work and financial data. When the final N release is out, the Pixel C will become my work machine. It's almost there.
I'm naturally paranoid. I change my long passwords frequently and use 2 factor authentication for everything. So if I can, I'll take a stock release. See my instructions for wiping Android devices: How to wipe an Android Phone: the paranoid editon
I could not flash the NPD90G stock bootloader because of an error "remote: unsupported command"
Here's how I fixed it.
Updated the SDK manager including SDK Tools and USB drivers.
With the Pixel C in recovery mode, {hold the power key and volume down}
In TWRP mount System and reboot to recovery
>ADB Shell.
From ADB Shell I ran
>fwtool vbnv write dev_boot_fastboot_full_cap 1 to reenable Fast boot.
Then I changed from TWRP to Fastboot mode {power button plus hold the volume up button}
>fastboot erase userdata
>fastboot erase boot
>fastboot erase cache
>fastboot erase recovery
>fastboot erase system
See Note 1. Below
>fastboot flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
>fastboot flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
Note 1.
The first time through I flashed the following line items which resulted in the resting robot Andi. I don't think I needed to do this, but if the above instructions don't work, run the following before continuing for {flash bootloader bootloader-dragon-google_smaug.7900.27.0.img}
>flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
>fastboot reboot-bootloader
>fastboot flash system system.img
>fastboot flash boot boot.img
>fastboot flash recovery recovery.img
>fastboot flash cache cache.img

It's nice of you to help a fellow XDA user. But I suspect he's already solved his problem of three months ago.....

Hi guys
I have the same problem:
- the bootloader is unlocked (Coreboot menu says so)
- fastboot says "secure: yes" but "unlocked: yes" too
- "fastboot flashing get_unlock_ability" returns "1"
- "fastboot flashing unlock" says that the bootloader is already unlocked
But I have no recovery and if I try to fastboot boot recovery.img it fails with signature verification error
Can I do something to unbrick the device?
Regards

My solution is very simple:
fastboot flashing lock
fastboot flashing unlock
fastboot reboot
And now let it boot.... and wait.
After the (failed) reboot check again: Now you can write all partitions... worked with my Pixel C

Make sure you have the latest version of fastboot and adb. I get these errors almost every month if I don't update.

@stevep2007, thank you so much! I've been dealing with this "remote: unsupported command" nonsense for days now after trying to revert back to an older Oreo version of Lineage. This did the trick!

How can I solve the problem when my Pixel C is not unlocked? My Pixel made an update and after installing the Update I got the green little man. Now I have no Chance to activate USB debugging etc. Its also not possible to install twrp.img
How can I go to ADB shell with locked bootloader? Or isn't it possible?
Fastboot devices shows me my tablet. ADB devices also show my tablet with "sideload".
But every try to flash my Pixel fails. I alway get the message .... remote: unknown command.......fastboot error: command failed
flash-all.bat showes that all "*.img are missing" error: command failed... unknown command etc.......
So any idea to get my Pixel working again? ADB shell would make it I think. But how with locked bootloader.

This did it for me!! Thanks much. I also updated platform-tools at the same time, who knows which did it

Stuck at Fastboot and KFHD Restore not working

Hey guys,
My KFHD8.9 had stuck in fastboot (after a RED SCREEN showed up for a second) for quite a few days. And none version of KFHD_SRTv1.2.0-1.3.5 worked to make it back - 1.2.0 not even work to be exact.
I followed several xda posts like https://forum.xda-developers.com/showthread.php?t=2495741
to solve this, but seems not working.
I'll appreciate if anyone can help out.
Thanks

Assume that you have fastboot driver installed, KFHD_SRT_v2.1.zip, boot.img and recovery.img for 8.1.4.
You can follow these steps to downgrade to 8.1.4;
1. Power off your KFHD.
2. run [fastboot -i 0x1949 getvar product] and connect KFHD, this will put your KFHD in fastboot mode
3. run [SR Tool.bat] within KFHD_SRT_v2.1 folder. and choose option 2 or 3. (I prefer option 2)
4. After flashing 8.1.4 to your KFHD, don't reboot, you have to downgrade your bootloader and recovery as well.
5. Run [fastboot -i 0x1949 flash boot boot.img] to inject 8.1.4 bootloader
6. And run [fastboot -i 0x1949 flash recovery recovery.img] to inject recovery
7. Finally run fastboot -i 0x1949 reboot
Wait for a while and you will have KFHD 8.1.4 with root enabled, thanks to onemeila.
KFHD System.img Recovery Tool by onemeila
After this you can update to the latest 8.5.1 and gain root via iroot.
Now I'm happy with Nougat (unofficial CM14.1 by transi1)
P.S. Sorry, I can't remember where I fetched boot.img and recovery.img of 8.1.4, you have to find it yourself.

This works.
Thanks ong14. Your method saved my Kindle from its soft brick.

Rooting Motorola G6 Play gone wrong

Hi everyone,
I bought a Motorola G6 play model XT1922-3 type 374B and wanted root acces on this device.
So I started by succesfully unlocking my bootloader using the following tutorial.
After this a started tried to root the device using this tutorial.
This tutorial doesn't link to boot images anymore so I was able to find the moto-g6-play-jeter-patched-twrp.img somewhere else.
I did the following things:
- reboot to bootloader [Succesfull]
- fastboot boot moto-g6-play-jeter-patched-twrp.img [Unsuccesfull]
The device did boot the twrp image but I was unable to interact with it in any way. I couldn't swipe or press buttons.
I made a short video to show this.
I wanted to retry the whole thing so I did reboot to bootloader but then I accidently entered the following command:
fastboot flash boot moto-g6-play-jeter-patched-twrp.img picture of command prompt
After this I wasn't able to normally boot my device. When I try to do so the screen goes black and says n/a in the left corner.
Please does anyone know how I could either be able to boot my normal stock rom again or to have a rooted rom?
Kind regards Sven Onderbeke

Hi Sven,
This isn't going to be the most advanced reply, as I'm not very experienced with this stuff either, but it seems you have accidentally flashed your twrp image to 'boot', wherever that is, which is why the phone isn't able to boot to system.
Can you still boot into bootloader and recovery (twrp)?
If so, then I'd suggest using fastboot to flash a sock or custom ROM. I'm not sure exactly which one though, you have basically the same model as me and that seems to use the JETER ROMS a list of which are over here (can't post links yet, so you will just have to search on mirrors . lolnet . com /firmware/moto/jeter/official/ or remove the spaces
I seem to have somehow lost the partitions on mine, but will start a new thread question about that.

Just flash a stock boot.img to boot. Then just flash TWRP to recovery. In TWRP, format data. Type yes. Then reboot recovery. Then Use TWRP to flash magisk. Done.

Hi again Sven,
I just wanted to let you know that I just downloaded the following RETAIL ROM
ALJETER_RETAIL_9.0_PPPS29.55-35-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
and used the following fastboot commands, one at a time.
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin
fastboot flash boot boot.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash oem oem.img
fastboot flash vendor vendor.img
fastboot erase carrier
fastboot erase userdata
fastboot erase DDR
fastboot flash logo logo.bin
fastboot reboot
Which rebooted into bootloader so pressed "start" and all booted fine now. It looks like we have the same device, so hopefully that will work for you too.
