Info needed for Unified Toolkit

If anyone can give me the following information it would be useful in adding the Pixel C to the Unified Android Toolkit.
1. Is the "Allow OEM unlock" option present in the developer options (needs checking before bootloader can be unlocked)?
2. What is the key combo to boot the device to fastboot mode manually?
3. Is it a standard bootloader screen (i.e. down volume and power to boot to recovery)?
4. What instructions do you get on the device after running fastboot flashing unlock to unlock the bootloader?
If anyone can fill in any of the information or add anything that would be useful then please do..
Mark.

1. Is the "Allow OEM unlock" option present in the developer options (needs checking before bootloader can be unlocked)?
A: Yes
2. What is the key combo to boot the device to fastboot mode manually?
A: Power + Volume down (when in landscape). The bootloader has an option to "Switch to fastboot mode" which you select with volume down and then the power button. It will switch to a screen that says "Waiting for fastboot command..." with no option to go back.
3. Is it a standard bootloader screen (i.e. down volume and power to boot to recovery)?
A: Yes. Here is a picture of it: https://goo.gl/photos/YQ5FVKf6HAWQWwd5A
4. What instructions do you get on the device after running fastboot flashing unlock to unlock the bootloader?
A: You are given the option to press power to unlock the bootloader or volume down to cancel. The device then says the bootloader is unlocked and it will reboot in 30 seconds. After that, you get the recovery robot with an "Erasing" dialog.

Thanks for the quick response. Just need a bit more info about the actual bootloader.
Do you know if fastboot commands can be sent after booting to the bootloader mode? Or do you have to boot to bootloader and then select "switch to fastboot" to accept an input? If you have used adb with the device could you run adb reboot bootloader and tell me if the device goes to the bootloader or the fastboot screen.
I also need error messages when unlocking. If you (or someone else) could run the following that would be great.
1. With "Allow OEM unlock" NOT ticked, boot to fastboot and run fastboot flashing unlock >> what is the exact error message.
2. With the device already bootloader unlocked, boot to fastboot and run fastboot flashing unlock >> what is the exact error message.
I think thats all thats needed for now to make a basic toolkit for the Pixel C to unlock, backup data, flash stock image, etc. If a custom recovery becomes available then it will then be very simple to add a root process.

I am heading to bed but if nobody has replied before I get to work this afternoon, I will be happy to get answers to the rest of your questions.

If I boot into the bootloader, I am unable to issue fastboot commands until I select "Switch to fastboot mode."
Using ADB, when I issue the "adb reboot bootloader" command when the device is on normally, it goes directly to the fastboot screen and says "Waiting for fastboot command..."
When "Allow OEM unlock" is not ticked and I boot to fastboot and issue "fastboot flashing unlock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing unlock
...
FAILED (remote: Device already unlocked)
finished. total time: 0.005s
When "Allow OEM unlock" is not ticked, the bootloader is unlocked, I boot to fastboot, and issue "fastboot flashing lock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing lock
...
FAILED (remote: Enable OEM unlock is not set)
finished. total time: 0.020s
When the bootloader is unlocked and in the fastboot screen, if I issue "fastboot flashing unlock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing unlock
...
FAILED (remote: Device already unlocked)
finished. total time: 0.003s
Let me know if there is anything else you need.

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

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

In the scenario described by @llopa this solution does not work.
In that scenario there are no solutions

[Flashing STOCK ROM from Custom Rom] [No Recovery Mode, Fastboot accessible]

I followed these steps and now my Asus zf2 (ze551ml) is back alive! For the issue mentioned below, I didn't find much anywhere so I thought I'd put here what helped me.
Issue: Only fastboot mode accessible, can't enter recovery. (Also my bootloader was locked, MM bootloader, No OS). After selecting recovery mode from bootloader, again it enters fastboot, i.e the process in video above couldn't install the recovery (This must be because my bootloader was locked). I tried unlocking the bootloader by the .bat files available on XDA but since I'd not enabled OEM unlocking, unlocking failed everytime. My OS got wiped out, so only fastboot mode was accessible.
Solution:
I believe you have installed Minimal ADB and fastboot on your PC.
Download the raw file from the XDA thread.
Now first of all, change extention of the .raw firmware file to .zip.
Then just extract all files from it into adb and fastboot folder.
Now in folder (where you placed files from raw firmware and adb and fastboot tool folder) at empty place anywhere in folder hold Shift on computer keyboard and right click with mouse. Now click open command window here.
Perform the following commands one after another:
1. fastboot devices ( see if it is recognized: else plug out usb and plugin again, if USB debugging was on then this will definitely work)
2. fastboot oem erase_osip_header
3. fastboot oem start_partitioning
4. fastboot flash /tmp/partition.tbl partition.tbl
5. fastboot oem partition /tmp/partition.tbl
6. fastboot erase system
7. fastboot erase cache
8. fastboot erase data
9. fastboot erase APD
10. fastboot erase ADF
11. fastboot oem wipe splashscreen
12. fastboot oem stop_partitioning
13. fastboot flash splashscreen splash_sign.bin
14. fastboot flash token MFG_BOM_Full.bin
15. fastboot flash ifwi ifwi-prod.bin
16. fastboot flash boot boot_sign.bin
17. fastboot flash recovery recovery_sign.bin
18. fastboot flash fastboot droidboot_sign.bin
19. fastboot flash APD APD.img
20. fastboot flash system system.img
21. fastboot reboot
Phone will successfully reboot into system. Don't worry, first boot gonna take a little longer time.

Download raw file
Hello,
From where I can download raw file? Can you please provide a link?
Thanks in advance

Get Stock boot image without flashing TWRP

Keep stock recovery and extract the boot image.
You'll need.
Unlocked bootloader as guided here
adb/fastboot and proper drivers on PC.
TWRP from here. Any recent build will do, just grab the latest one.
Steps:
Reboot to fastboot
Code:
adb reboot bootloader
In fastboot, verify it's working properly and get the current slot. The result is either a or b
Code:
fastboot devices
Code:
fastboot getvar current-slot
Now boot into TWRP temporarily. The touchscreen will NOT work(a known issue). Just leave the phone connected
Code:
fastboot boot Twrp_3.5.2-10_EduardoA3677-billie_OxygenOs11_Android11.img
adb should work now. Extract boot image(s).
Code:
adb devices
Code:
adb pull /dev/block/bootdevice/by-name/boot_a boot_a.img
Code:
adb pull /dev/block/bootdevice/by-name/boot_b boot_b.img
Now we have boot_a.img and boot_b.img in current folder. Both should be 96MB or 100,663,296 bytes.
Depends on the result from step 2,
if it's "current-slot: a" then use boot_a.img. if it's "b" use "boot_b.img".
Once done, reboot the phone.
Code:
adb reboot
Now with this boot image, follow the guide to root.

Question Root OXYGEN OS 13 MT2111_11_F.11 ?

Is there any way we can root MT2111_11_F.11 because for me fastboot appears to be missing as when i try volume down and power it just keeps on restarting after a see the fastboot screen for 0.01secs.
I tried using adb reboot bootloader as well but didn't work.

You should use adb reboot fastboot instead. Note that this mode doesn't allow to unlock bootloader if it is locked. But if bootloader was unlocked earlier, you may use flash command to flash patched boot.img
Code:
fastboot flash boot boot.img

go to github magisk, get apk install it on your phone, download your Full OTA, extract it via payload.bin extractor and take out boot.img then patch boot.img using magisk and do fastboot flash boot magiskpatchedboot.img

Original boot.img for oos f11 to patch

Button combination = Fastboot Logo flashes for a split second, Phone instantly restarts to system, no access to bootloader therefore impossible to use flash commands
adb from system > reboot to bootloader = exact same as above.

Not bootloader, but userspace fastboot (fastbootd) mode. The command is
Code:
adb reboot fastboot
