I was on nougat and went to downgrade and followed ALL instruction apart from one - which was something I missed with translate until i visited the htc page for the tenth time trying to fix this.
:silly: :crying: ----- I didnt change default location whilst running nougat -----:silly: :crying:
I flashed the c432 oem file, and I have tried to update to b151, b150 and b161 all through the update.app method. to no avail.
I have tried flashing everything manually through adb pushing AND fastboot after using the extractor and everything works EXCEPT the system.img. I am faced with an error telling me it has failed, 'unable to mount /system' - - - This message comes through regardless of what I do and im panicking

I have the vns-L31 however ive just opened dc unlocker and its showing my model as 21
i can access fastboot and rescue mode as well as twrp although when flashing im faced with the /system error

It is written, on htcmania, using c432oeminfo and b130.

Code bootloader
Twrp meticulus.
Install c432oeminfo.zip, power off
Restart dload c432b130.

Yes, I noticed that from time to time, in bootloader mode, it is written unlocked, but as the device bootloop (bug) I believe it too. so
I retype systematically the bootloader code to open.

If you have your bootloader unlocked (if you don,t have it, unlock it) and flash TWRP. After that, flash B130 for your VNS-L31. Done.

Unlock yor Bootloader again. And try flashing again.
Have hade the same problem. My bootloader showed unlocked, but he was not.

Shut down your device. Press the switch off for 10 secounds.
When the phone is off, swith on and same time with vol + without usb-kabel, and otherwise try it with usb-kabel.
When you stock recovery starts. You can try a factoryreset.
When you Revolution recovery starts flash oem.info again and perform the dload methode with your right MM UPDATE.APP.

OK. Go to bootloader and flash:

fastboot flash boot boot.img
fastboot flash system system.img
extract this files with: Huawei Update Extractor from your Original UPDATE.APP

Hi guys, i have the same problem after doing some ****, flashed stock rom from lineageos 14 and a lot of things that i'm trying now to unbrick my phone... i cant enter to the erecovery with the 3 buttons method, wathever i do, and i dont have any idea on how to unbrick my phone... I hope someone could help me

very very very important

i upgraded my p9 lite to nougat via unofficial method using firmware finder app and when it finshed i found many apps not exist anymore
and the build number bwcame nrd 90m test-keys
now i want to back to marshmallow but i can not i tried every possiple method but i still cant
i unlocked the boatloader but cannt install twrp
can anyone help me please

Did you try the revolution twrp for nougat? You should flash that one, install the oemfile and dload a marshmallow file, after that go into recovery and hard reset your phone. This should get you back to marshmallow.

Or not to go down to MM. If you are always in nougat, But installs HWdataFull that suits you.
Install recoverynougat b9, MOUNT data, install HwDataFull, reboot bootloader, install recovery stock nougat. Reboot recovery and factory rest. Reboot.

Did fastboot gave some error message, also did you only test to go to recovery straight from fastboot, because that is other recovery which can't be changed.

Just to make sure because the recovery stuff with this device can be at start a bit confusing. Please check does the recovery you boot into have factory reset option in it.
Also can you give a link for the twrp you flashed?

1. Booloader unlocking only affects to what you can flash in fastboot, it doesn't affect stock recovery funtionality.
I asked about factory reset option, because I wanted to make sure you aren't booting to "recovery2/eRecovery". (It doesn't have factory reset option)
2. Avoid using kingoroot and other oneclick root apps if it is possible.
3. Your firmware version doesn't matter.
4. Bootloader unlocking can't cause crash. Locked bootloader could cause crash if system is modified(I think), but you would still be able to get recovery.
One way to make sure you boot to normal recovery is to connect your phone to pc --> open command line --> type "adb reboot recovery". This won't take you to erecovery
I can't do any better help with the current information.

After you successfully flash the recovery with fastboot (always use the latest!) You need to do these things in order (and fast) in order to but to TWRP. If you don't it will boot to stock recovery and you have to fastboot flash again.
You must
a) write fastboot reboot in the console but don't pass Enter!!
b) hold VOLUME UP
c) (still holding VOL UP) presss Enter and remove the USB cable immediately once it says your device is booting now.
Keep holding VOL UP until you boot to TWRP. Allow modifications.
For root you will flash Magisk (you know, normal zip), which a) is open source, so no sneaky stuff and b) can hide root from apps as a bonus. You can always get the zip here: http://tiny.cc/latestmagisk
Important: If you have other root solutions install them for example SuperSU has an uninstall option. Then flash Magisk

The recovery you go from fastboot is eRecovery. You can't boot to stock or TWRP recovery directly from fastboot. If you choose shutdown from eRecovery then you can just go to TWRP with normal way (power + VOL UP). Going to eRecovery doesn't undo TWRP installation. (This also means you can do force update even with TWRP installed, I think, not 100% sure)

I do this every time. See surdu's post here. Fastboot reboo is just a reboot, so the familiar key combo will boot to recovery.

@ADITYA_KUMAR this has been asked and explained many times and once more.
- Take Backup
- get Elemental-X kernel (see development section and download correct one )
- flash with TWRP
- get latest SuperSU : SuperSU

What happens if you select Recovery from Bootloader ? Is it booting in Stock Recovery ?
In TWRP go to Backup and make backup of /system /data /boot.
If anything bad happens while flashing/Rooting then you can restore it.

The first time, you must open TWRP from the bootloader directly or the recovery gets overwritten.
For rooting, you can flash Magisk instead of flashing SuperSu. Other steps remain exactly the same.

This is your problem. You must open recovery from the bootloader menu the very first time. Or TWRP is overwritten with stock recovery. I don't know why that is. But that is how it is...

Flash recovery - fastboot flash recovery twrp-xxx.img
Open recovery from bootloader menu (by using the volume and power buttons)
From there you can reboot and your recovery will work normally after this, most probably.

Try commands,

Then directly boot into recovery,
Then again boot into recovery through twrp itself (there is option for it in reboot) or try anything.

Thank you guys i successfully rooted my moto g4 plus(xt1643)

Stuck on 'The bootloader in unlocked' screen

Hi
Have an unrooted international version of OnePlus6t. decided to upgrade from 9.0.17 to 10.0.1 and root. Decided to follow [Ultimate-Guide] ★ OnePlus 6T OOS-10 TWRP-Root-Magisk from OOS-9 guide, Method 3.
Installed 10.0.1 , phone booted OK,
restarted to bootloader
Stock Recovery >> "Wipe data and cache" > "Erase everything" > Reboot to Bootloader
fastboot flash boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img
Changed to Slot B
reboot to recovery
Stock Recovery >> "Wipe data and cache" > "Erase everything" > Reboot to Bootloader
fastboot flash boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img
Now phone is just showing "The bootloader is unlocked and software integrity cannot be guaranteed blah blah blah' screen. What can i do?
Please advise
Thanks in advance
P.S. Power+VolumeUp buttons combination just turns phone off. When I turn it on again, phone stucks on the same screen
UPD: OK I am able to get into fastboot mode. What can be done next?
UPD 2: Using mauronofrio's AllInOne tool I was able to boot twrp for Pie, change slot back to A and voila! I have TWRP and Andriod 10.0.1 back again. Hooray!
Now the only thing that bothers me is that seems that I have Q on SlotA and Pie on SlotB. Can it cause any unwanted effects?

How did you force getting into bootloader please? I'm in same boat!

Well the first thing is that you can't flash twrp as a boot partition. Twrp is a recovery, not a kernel. You are supposed to to fastboot boot twrp

Disconnect phone from computer, press VoulmeUp+Power keys together to turn off the phone, then press VolumeDown+Power keys to get into bootloader

You erased everything? I guess you have to flash your image again (10.0.1). Just don't use twrp if you don't need it. Go back to stock recovery, install 10.0.1. let it boot. Then after everything is done, flash the patched boot.img (install magisk manager first though).

I already did that and my phone is working now with OOS 10.0.1. I wonder should i get to TWRP somehow, change to SlotB and flash stock 10.0.1 again?

Same issue caused by same process. Not able to get into bootloader screen using the method described. Ugh
Luckily I still have my last phone I can use until I figure this out. Yay Nexus 5X!

entered -
fastboot flash boot twrp-3.3.1-28-fajita-Q-mauronofrio.img

Why do you need TWRP?

Just to flush stock 10.0.1 to SlotB

Did you turned off your phone? You should hold VolUp+Power buttons until phone turns off - about 10-15 seconds. Then Press VolDown+Power to get into bootloader

You don't need TWRP for that. If you only want root with stock oxygenos, I'd recommend not to install twrp.
You don't need it, unless you want to install custom stuff (kernels, roms, patches etc) constantly.
If you just want stay on stock OOS. Just update through android and patch magisk after update with installing to inactive slot (before reboot).

And what for? A/B devices are not meant to have the same rom on both slots.
Just run your Android 10.0.1 now, don't bother at all about slots, and on next update it will install on inactive slot, you'll just have to install Magisk on inactive slot before rebooting as said just above.
It you don't plan to flash custom ROMs you don't need twrp.

As I stated, I followed the steps the OP had posted. The phone would turn off, but would not boot into bootloader mode, it just showed the initial screen. Believe me, I tried!
I've sent the phone back to OnePlus for repair/replacement, I was well under the warranty period.

Hi
Have an unrooted international version of OnePlus6t. decided to upgrade from 9.0.17 to 10.0.1 and root. Decided to follow [Ultimate-Guide] ★ OnePlus 6T OOS-10 TWRP-Root-Magisk from OOS-9 guide, Method 3.
Installed 10.0.1 , phone booted OK,
restarted to bootloader
Stock Recovery >> "Wipe data and cache" > "Erase everything" > Reboot to Bootloader
fastboot flash boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img
Changed to Slot B
reboot to recovery
Stock Recovery >> "Wipe data and cache" > "Erase everything" > Reboot to Bootloader
fastboot flash boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img
Now phone is just showing "The bootloader is unlocked and software integrity cannot be guaranteed blah blah blah' screen. What can i do?
Please advise
Thanks in advance
P.S. Power+VolumeUp buttons combination just turns phone off. When I turn it on again, phone stucks on the same screen
UPD: OK I am able to get into fastboot mode. What can be done next?
UPD 2: Using mauronofrio's AllInOne tool I was able to boot twrp for Pie, change slot back to A and voila! I have TWRP and Andriod 10.0.1 back again. Hooray!
Now the only thing that bothers me is that seems that I have Q on SlotA and Pie on SlotB. Can it cause any unwanted effects?

I am currently experiencing the same issue, how did you get it to go into fastboot mode? I've been traying for hours!
