Relock your phone again. Flash now the stock recovery. Then it's alright.

i think you didnt understand what im saying bro. i unroot and relocked already after relocking my phone got stock in eRecovery and i cant get out even unlocking again etc. still im stock

To complete your initial operation, you need the recovery. From your description, I see you had TWRP before. That will not do. Flashing in the bootloader you can only unlock with OEM. So, relock, recovery flash and then lock again.

yes your right after relocking my phone i lost my twrp.. thats the time im stock in eRecovery... did you mean that i will unlock it again? not relock cause it is already relocked sir.. i will unlock it again to flash and then lock it again? the question is how? i already put my code to unlock my phone again but it doesn't work anymore cause i cant flash using adb fastboot anymore.. adb fastboot cant read my phone since i relocked.. sorr for my bad english.. i hope you understand what im saying..

My English is also not better. I understand you. Have you ever tried the device with key combi in the recovery to start, without usb cable? Separated from pc and charger?

how sir? i dont get what you mean... can you please show me a tutorial?

So I wrote it in my root tutorial:
Button combinations:
Fastboot Mode: Vol.- and Power with PC connection
Recovery: Vol. + and Power without PC connection
eRecovery: Vol. + and Power with PC connection
All system reboots always without PC connection.
Without PC connection means that the cable from the PRA is separated, only from the PC is not sufficient.

With the PC program "DC Phönix" you can save it again. Unfortunately I do not know about it. Google knows more.

Help..Error Mode:No Recovery image,Load failed ( no fastboot )

Hi, I have P10 VTRL09 .. A couple days ago i did relock bootloader and now i can not enter my phone.it stuck at Error mode.
I tried almost every method but it always comes back to error mode. I discharge the batterry and charge, if I am lucky, sometimes it will boot into the system but it will black out. I can not do anything except turn off, but while it was in this stage, i could connect to pc and get detected. pc try to install MTP driver but it also failed. I tried command in adb, it also failed (waiting for devices) ....
Issues :
1.boot loader locked
2.no recovery ( can not be load )
3.can not enter fastboot
4.can not force update
5.PC not detect
Question : Is there a way to make my phone go to fastboot ? so i can relock bootloader with adb and flash new firmware.
i appreciate all the help...please help me.

I have exactly the same issue. With identical error codes. Still trying to work out a solution.
on the Huawei website, the had a bootloader.img installer for older models but none for the p10/ p10 plus
Any advice would be appreciated

Let phone completely discharge even it power off automatically. Then put the phone on the charging it will boot up to system then go to settings >advanced settings>back up&reset> reset all settings

when it boot i cant see anything except black . i can only turn off or volume.

Connect with pc and press power and vol-
It should boot into fastboot. You got the error cause wrong or broken recovery.

3-what is your model number L09CxxxBxxx?

I have sam problem last 3 days and i cannot solwed

Hi, I was able to solve it in this way.
Let the phone download 0% battery
connect it to the PC, pressing Vol - & power.
The phone will enter fastboot.
flashing the stock recovery
put the System in an SD and press vol + .vol - y pwr.
The phone will update and will light normally.

Hi, I was having the same problem. Mate 8 EMUI 8.
After looking everywhere and trying all the options available, I wasnt able to resolve.
Finally, I tried FunkyHuawei and got my system back through eRecovery.
Gave them the readings like version no. , build no...etc through fastboot. The required info is on their site. They then reverted with a link of the firmware which I flashed through their FuHunbrick tool. It force updates the entire full last version.
After flashing and booting, the system didnt boot but was able to go to eRecovery and restored my previous version.
If you or anyone else stuck at this error, they can try at their own risk as they dont guarantee anything.
Edit: you should and will be able to boot into fastboot once the battery is totally down and phone shuts off completely. Just press volume down button and insert usb. Try again and again if it doesnt work first time.
Thanks.

Help
First sorry for my English
I have a similar issue:
Huawei P10 Lite
I managed to install TWRP, but when I did that I lost the OTA upgrades, then I tried to install the stock recovery and then the phone doesn't start.

Hi, let the phone battery dry out totally first. Totally. It should not vibrate at all when you press power button. Leave for a couple of hours more.
Then recharge to 50℅ or more and restart and see if you get to eRecovery or other options.
Are you getting any error screen after logo?
You will definitely get to fastboot by pressing volume down button and inserting usb. Try again n again.

Hi. I did the battery part and the part of the pressing the vol - is and connecting to pc. It started but didn't got into fastboot or bootloader, just turned on normally and then I ran the adb command "adb reboot recovery" and I had to do the battery part again. I am afraid to run "adb reboot bootloader" because the risks of the draining out the battery. I mean my phone does not enter into recovery.

Phone can't boot stuck at "Your device is booting now" Please Help

Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery
Code:
adb reboot recovery
. When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same. Now when I try to reboot the phone it shows ultra low baterry symbol and then boots to "Your device..." screen.

Which twrp you flashed? Check the correct twrp in my signature for honor 5C repository.

Did you try all method to going in fastboot.by adb fastboot command or by pressing vol- and power button?

Hi guys, thanks for your replies.
I somehow managed to boot to fastboot after waiting for the battery to go out completely. From there I used the following commands in ADB from the extract of a stock update.img :
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And it worked ! The first boot was veeery long and now it's normal again.
Now my last concern is that I still have bootloader unlocked. As I wish to come back to factory state and avoid the warning message on boot, do you guys think it's safe to re-lock bootloader ?
I'm kind of scared to try anything else and screw the whole thing now
Thanks again for your support

Can you please explain to me how did you managed to boot into fastboot? I tried waiting for the battery to drain completely. Now I can't fully charge my phone. When i connect it with charger. It starts normally charging like it would with 0% battery then after a few moments the honor logo shows up and then the screen "Your device.." shows. When I try vol- and powerbutton it vibrates and shows the red lightbolt then after few moments it boots the same way into the your device screen. When I connect it to the pc it doesn't react. I don't even hear the classic windows beep sound.

Now you have firmware zip, extract it amd you will get few files. Use dload method as given in my signature and you are good to go.
Else use Huawei extractor and browse to update.app you just got in above downloaded zip. You will get boot, recovery, system img you need.

I downloaded some firmware versions and extracted them. I don't know which is for my device. So I tried one of them. I flashed boot.img and recovery.img but I din't flashed the system.img, becouse it was too big. When I tried to reboot the phone it was the same. The fastboot was no longer accessible. I put the phone into servis but they didn't fixed it. it's the same but I can enter erecovery

Xiaomi has auto bricked after update- need help

Hey guys, i have MI A2 cellphone, and after auto update programmed to three hours the smartphone show "AndroidONE" logo and then shutdown, i tried "Fastboot oem unlock", but it is my output:
PHP:
C:\Users\Lucas Daniel>fastboot oem unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
Finished. Total time: 0.000s
. I'm desperate, I do not know what to try anymore, I believe I do not have unlock OEM activated, someone can help me?
Sorry for bad english, i'm from brazilian.

@LukeSkyPTBR
It's a well-known issue. One update was revoked as soon as Xiaomi has found out about phones bricking once it's installed. There's no way you can fix it by yourself except if you have ordered your phone from China (and so no warranty you have) and have experience in disassembling phones. There's a thing called test-point, do some research if you are self-assured in that area. Otherwise let your authorized service center make everything for you. It is a warranty case, either way.

Thanks, looks that, unfortunately, my unique solution is test-point for activate EBL Mode... I will leave the topic open for the case of i get other solutions... after 3 days, if not get, i will close and the unique solution will really test-point.

Try rebooting it a couple of times and see if it boots. Or plug it to a charger and try booting it once it starts to charge successfully. If all fails, flashing via EDL might be your only option.

Try rebooting more than couple of time. Phone is supposed to switch to the other slot of A/B where original ROM (before update) resides. When it finally boots, get developer rights, switch on ADB Debugging and OEM unlock, thus next time update soft-bricks your phone you'll be able to unlock (or even better unlock immediately after successful boot not to loose your data in future).

Isnt Fastboot OEM Unlock command deprecated ? Shouldn't you use the unlock / unlock critical command ?

How can I do it? I leave the phone in the charger for a long time? Or do you need the power button for a long time?
I tried to press the power button for 2 minutes and nothing happened.
When i leave the smartphone on the charge, after 50 minutes, show for me 100% percent, so, i pressed power button and the screen stayed lock in "AndroidONE", nothing happened, until try again press power button.

I can enter fastboot mode, but this is not enough to do run commands up. I would need unlock bootloader(OEM).

If you can enter fastboot then you can go to EDL mode by typing 'fastboot reboot edl' and then use QPST to flash the latest stock rom.

Do as tabun1994 said.
This will hopefully get the system up again.
The commands I wrote would unlock the bootloader. What else could I have meant?
If you succeeded with tabun's method, then you probably would only need to enable "USB debugging" and "OEM unlocking" in the ROM's developer options (which you'll enable by hitting "build number" in settings like 10 times or so).
Then you would connect the device and accept the 'trust this device' warning.
After booting to fastboot now, the commands I wrote should work and unlock the bootloader (if you even want that when your system is running again).

If you can enter fastboot then you can go to EDL mode by typing 'fastboot reboot edl' and then use QPST to flash the latest stock rom.

This command needs OEM Unlock :/
this is my output: fastboot: usage: unknown reboot target edl

The test point method is actually easy , you have to dissasemble the display , easy procedure , remove the battery and short the two test points with tweezerz or something ,and in the meantime you plug the usb cable into the computer. It should install the Qusb_Hub drivers , and with miFlash you should be able to reflash the firmware . I bought a phone that was in this state and fixed it using these steps.

No more solutions, I will do the test point method, thanks to everyone who tried to help otherwise.

No it doesn't, i have tried this method on locked bootloader, go to this link - https://forum.xda-developers.com/an...e-how-to-reboot-to-edl-fastboot-t3394292/amp/
And download the fastboot_edl.7z , your phone will be in edl mode, I think you don't have the proper platform files which has caused the problem.

What is your smartphone?

edl mode 9008 v40 very easy

(french) hello
I could not start in edl mode with the xda instructions but I found a videos
phone on android, connected to the computer by usb. you keep pressing the power button and the volume down button.
when the screen goes black immediately you strafe the volume + button for 2 sec.
the secret is the windows song if the phone is on. when you hear windows song strafe the volume +. i know I did it with my phone off and my phone on quite a few times
normally your computer will recognize the phone in the correct mode. if there is a problem do not forget to install these drivers and restart the computer as it will stay in edl mode and will be well supported.

that's funny visibbly before you unlock or reflash the original bootloader the phone don't have fastboot mode with me. but fastboot don't work well in windows. it work erfectly on linux ubuntu with me at exemple.
thanks for your attention

yeah, it is very easy

So this is how you go into fastboot ?
I have the V405 EBW & I am unable to go to fastboot to get the device ID.

no no we should not confuse.
there is download mode in originale lg phone for flash stock roms
there is "edl mode" for unlock bootloader
there is fastboot mode when you unlock the bootloader with this screen.
a tips. root first your phone. 2 backup your firmware. 3 flash twrp. i had problem because i don't do this. there is stock firmware already rooted. its easily.

Unfortunately, I am unable to root because I am unable to unlock the bootloader (because I can't go to fastboot to get Device ID & send it to LG)

But you can get to fastboot, just not the way you read on the internet.
The device doesn't have fastboot available, until, you put it in edl mode and use qfil to flash the 'engineering' abl. That's what gives you fastboot.
You could, at that point, use fastboot to get the info for unlock.bin. But why? because at that point you can just type 'fastboot oem unlock', and it's unlocked.

Unlock only works with Oreo ??
I have Pie
How do I downgrade without root ?
Is it possible ?

If I can flash a firmware without root
I'd be more than happy to flash a custom rom which has LG's apps instead of Google annoying ones.
