Bootloader locked and unable to boot the phone

Thank You seniors for supporting me for the last few days.
This thread is about my discussions with you http://forum.xda-developers.com/nex...6-recovery-flashable-fastboot-t3066052/page54 and the following pages.
I have to move here as my issue was off topic in that thread.
When i type fastboot oem unlock command it says check OEM unlock option is developer settings.
But my problem is i cant boot my phone to go there.
I erased everything and locked boot loader by mistake.
I can boot my phone to bootloader and recovery i cant flash anything via fastboot as my bootloader is locked.
But i can do adb sideload in recovery.
I am now on lmy48i recovery i tried lmy48i from lmy47z it says the file is incorrect and i am already on lmy48i.
Kindly help.

If you have TWRP installed, there may be hope. If not, RMA is the only option.

As @Evolution_Tech told you, IF you have TWRP installed you can boot into recovery and move a flashable ROM.zip from your PC to your phone.
If you do not have TWRP Recovery installed, you are out of options. You will have to return it for repair or replacement.

You don't type $.
Anyway, as above, no TWRP recovery, nothing you can do

seems like you could flash a factory image in Wug's toolkit if you can into bootloader mode. (power off/ hold vol down + power button at the same time)
then flash a factory image in "soft brick" mode.

doesn't matter, you can do it with a locked bootloader. it asks if your bootloader is locked and then flashes.

It does matter. It can only unlock the bootloader if the bootloader can be unlocked. It cannot unlock the bootloader if the bootloader cannot be unlocked, which is the case here.

I dont care about any data inside my phone.
Let me explain how i messed my Nexus 6.
I wanted to flash a fresh lmy48i full version so i erased everything via fastboot.
Then i started flashing using flashall.bat it flashed everything except system it said the device cannot accept such a huge file.
I thought may be i was unlocked it doesn't wanna work so i typed fastboot oem lock the device said successfully locked and thats the end of my N6 i can't unlock it anymore because it says enable allow oem unlock which i cant do because i erased system. when i try to boot i see GOOGLE logo but nothing after that i even left it for more than an hour nothing happens no boot animations.
Now i cant flash anything via fastboot because my bootloader is locked.
But i can get into recovery and i have the option to do ADB Sideload.
When i try lmy48i from lmy47z ...zip my phone says expecting lmy47z release keys but device already has lmy48i ...relese keys etc...
So i am thinking the next update which google releases would be xyz from lmy48i .zip and that will solve my problem.
After reading forums i understood my mistake was not using the latest fastboot file that is why my system.img failed and it said the file is huge latest fastboot.exe uses sparse method if the file is big than the acceptable size of the phone.
Prior reading would have saved my Nexus 6.I leant a good lesson.
Do you thing xyz from lmy48i ...zip in future can fix my phone?

Only works if you have TWRP installed. And IF you have TWRP installed, there are other, easier solutions....

Every Software Lock should have an unlock procedure.
That is what i am searching for.
@ Danarama:I am noticing your reply's for a while now.where ever i post you respond saying RMA is the only option. Please don't make conclusions.If you don't know unlock procedure then ignore my posts.
I live in Kuwait and i bought the phone from UAE paying customs duty delivered to me via DHL no local warranty.
So i am trying all options.Let other's respond.
For people living in US,UK or few other countries RMA might be an easy procedure so they just use that option.
There are Nexus lovers everywhere so don't talk about RMA or Direct Play Store return procedures here after.
I am using Android since 2010 and i have played, rooted, reinstalled etc... with lots of android phones. I was shocked when i ended up with a dead lock like this that too on a nexus.
How stupid is this Google's Anti Theft Feature with out a back door option even for genuine owners like me.I am not a theif.I know my google account credentials which i used on my nexus 6.
Atleast Google should give an option to genuine owners to prove themselves by logging into their website with the gmail ID used on the phone to request for an unlock procedure.

How to Unlock Bootloader, Flash TWRP, and ROOT LG G4 H811 T-Mobile.

Now, I know this tutorial exists all over the place, like one-click and UnjustifiedDev tutorial but none seemed to work. I am sharing the steps and method I used IN-DEPTH command for command on how to unlock, flash, and root the LG G4 from Tmobile.
NOTE THIS WILL FACTORY RESET YOUR DEVICE SO BACKUP ALL YOUR DATA
1. Activate developer settings by entering the about section and tapping build number 7 times.
2. Enter your developer settings and MAKE sure you have 'Allow OEM unlock' and 'USB Debugging' enabled.
3. Download the latest SuperSU zip and move it onto your SD card.
4. Using the android issue SDK. Open a command window and link it to your SDK folder where ADB is located (typically Platform-Tools)
5. Once the Command window is linked to the folder, connect your device via USB and allow the connection.
6. On the command window type 'adb reboot bootloader' and the device should reboot with the fastboot options on the upper left of the phone screen
7. Once again on the command window type 'fastboot oem unlock' and the command window should say OKAY and complete the action.
8. To Confirm that the device is unlocked type 'fastboot getvar unlock' and the window should respond with 'Unlock: YES'
9. Now download the latest available TWRP and drop it into the platform-tools folder where your ADB.exe is located.
10. On your Command Window type 'fastboot flash recovery "NAME OF TWRP FILE" if you get the error ' cannot load 'twrp-X.X.X.X-h811' you need to add .img to the end of the filename
11. Once the process completes you will see 'target reported max download size of 536870912 bytes
sending 'recovery' (32968 KB)...
OKAY [ 1.088s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time:'
THE FAILED UNKNOWN COMMAND NOTICE CAN BE IGNORED
12. Once the process completes the device may not let you enter recovery from the traditional method using the buttons on the back of the phone so the easiest method is to, on your command window, type
'fastboot boot twrp-2.8.7.0-h811.img' and the device should respond within just a few seconds and reboot into TWRP.
13. Once the device reboots, enter twrp and tap on install and locate the SuperSU.zip and allow it to install.
14. Once the process completes successfully, wipe cache to be safe and reboot your device.
15. Resetup your device and restore your data if necessary and install a root checker from Google Play to confirm root!
THATS IT GUYS! This took me a long time to figure this out and it's a combination of different methods to get it to work!
All credit goes to the Devs of TWRP and SuperSU!
I posted in General because I'm a new user so please move to appropriate forums! thanks!

This thread should be closed as theres already a proper one on here..http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227

The guide you linked does not show how to unlock the bootloader or install TWRP to allow the install of SU for users that are already on Marshmallow. The other guide would have been perfect if I already had bootloader unlocked and SU installed.

Yes it does. You do not need to use any codes, just enable oem unlocking in dev settings and type fastboot oem unlock and it will be unlocked.

Can't get twrp installed
Thanks for the step by step directions. I'm having trouble restarting my H811 after I've flashed TWRP. My device doesn't respond to the button method of entering recovery and 'fastboot boot twrp-2.8.7.0-h811.img' command doesn't do anything. My device is 20i and I've unlocked the bootloader. Any ideas? Seems like I've tried everything and can't get TWRP to install. Any help would be great...thanks

I have the G4 LGUS991 gotta can I tell if it's h811?

4. Using the android issue SDK. Open a command window and link it to your SDK folder where ADB is located (typically Platform-Tools)

Can't remember which thread, but I ran into the same problem you have and solved it by using an additional command like fastboot erase userdata. If you google it, you'll see the commands I mean. Basically, I had to factory reset the device through fastboot first (it sits there for several minutes to do this) before installing/booting twrp. And yes, the log will show that the process was successful, not a failure as mentioned by OP. Once I did that, I booted in twrp and flashed the rom zip without any trouble.

So, you guys mean we have Marshmallow on T mobile G4, I didn't get it yet.
Please somebody give me a link to the OTA or update.zip for MM of LG G4

This one worked for me!
This is the only guide that worked for me.
I unlocked bootloader using adb, no problems...
I tried to flash TWPR with fastboot but kept getting errors. Booting into recovery got a dead android minion and red triangle with ! I ran this stupid recovery a dozen times and read a dozen threads with no obvious answers.
This guide says "ignore the error" and run fastboot boot twrp-2.8.7.1-h811.img which immediately opened TWRP and allowed SuperSU-2.71.zip to be flashed.
The part most guides are missing is the fastboot boot twrp-2.8.7.1-h811.img, so my thanks go here. Some other guides are so difficult to read and follow.
Thanks OP !
Yes, MM Android 6.0 went OTA for T-Mobile a month or so ago...

If you are already on Marshmallow, can't you do the 'fastboot oem unluck' with ADB and install SuperSU through the play store to get root? The part for TWRP would only give you the ablity to flash other roms.
Edit: Nevemind I'm wrong. You need TWRP to install SuperSU which roots the phone. SuperSU in the Play Store will only grant root acess to your apps.

I've just got a H811 and it automatically updated to Android 6 when I loaded it up. I will be giving this guide a go this evening. Many of the other links on the web are for lollipop and were released when the phone came out, so I'm thankful that this seems straight forward. http://uslugi.nie-spamuj.eu/rtv,1,0.html Hoping that it goes that way.

How to lock bootloader or hide status: bootloader state: unlocked?
Sr for my English!

So I followed this guide and I appear to be soft bricked at best and hard bricked at worst. I did read the other guide linked in the second response and I found a major difference that might be my problem. So in the guide linked in the second response it doesn't say to even try flashing TWRP from fastboot. It says to just boot from it then install it from within TWRP. I followed the steps verbatim and my phone is currently stuck at the T-Mobile splash screen. Any suggestions? I have tried to boot into recovery by holding down and the power and releasing the power for a second when the logo comes up. I get into the Factory data reset screen and select Yes twice then the green guy shows up and the phone resets but stays at the T-Mobile splash screen. I don't have ADB or fastboot with the phone in this state.

hi Guys,
So i just wanted to make sure and present my ask -
So, currently twrp flashing and obtaining root is still buggy for those who have android 6.0 preinstalled? Is this a correct assumption?
Also, my ask - I dont want root but i would like a custom recovery so that I may flash custom fonts. My work email (Good for Enterprise) is very much needed (although i hate it to the core).
Can someone please answer me / correct if I mentioned something wrong?
Thanks

It's not buggy at all. All the tedium has already been bypassed if you already have Marshmallow installed.
Follow autoprime's original guide, steps 2, 4, 5, 6, and 8 under the Bootloader OEM Unlock + Root section. I would recommend a more up-to-date version of TWRP than 2.8.7.1 though. Go to TWRP's download site for the latest version.

Optional: Install cool modules to modify your phone further.

I found out that this ( http://www.wugfresh.com/nrt/ ) was an easy and up to date way to get rooted... Read all the instructions and watch videos if you need to before doing anything

Personally I prefer not to rely on toolkits. It's better to do things yourself so you can troubleshoot and fix if anything goes wrong.

I am in the process of trying the Magisk route and I'm having difficulty understanding the flash process. I have downloaded the Magisk-v11.1 zip to my Windows desktop and then copied it into the /Download directory on my Nexus 6. After googling a few things, I'm confused about how to flash / install on my Nexus 6. Some articles come up indicating I need to install TWRP Recovery, but I'm confused even more if I need to install this? Then I read another article (which I can't find now) about powering device down, then holding Vol Up, Vol Down, and PWR buttons to power phone back on and put in Recovery Mode (I think), and navigate and install the ZIP file. If this is the correct method, I didn't see an option to install from file or install from zip file.

Hey... You may flash TWRP recovery from bootloader using fastboot command. You can't root using stock recovery...
Download the latest TWRP from here and save it on your computer, preferably in the same folder you have ADB/fastboot:
https://dl.twrp.me/shamu/twrp-3.1.0-0-shamu.img
Just remove all security first before proceeding with the next steps (lockscreen scheme, password, pin. You can reenable them afterward. Just to avoid issues with twrp).
Your bootloader must be unlocked, otherwise unlock it first (you can find infos regarding bootloader unlock method in the general section of the Nexus 6 forum). Once/if the bootloader is unlocked, power down your device. Just press volume down and power button for a few seconds until you see a green Android laying down with it's belly opened...
Use fastboot to install TWRP using this command:
fastboot flash recovery twrp-3.1.0-0-shamu.img (the file you saved earlier on your computer).
Once it's finished, use the volume rocker and select "recovery mode" and press power button. It will reboot to TWRP.
Allow TWRP to make system modifications. Then tap install and go to the folder you saved the magical zip and install it.
Reboot and install magical manager as @snowrelyt said and you'll be ok.
Every info's you need can be found on the forum. If you're unsure, just ask again...
Good luck...

fastboot flash recovery twrp-3.1.0-0-shamu.img (the file you saved earlier on your computer).
Once it's finished, use the volume rocker and select "recovery mode" and press power button. It will reboot to TWRP.
Allow TWRP to make system modifications. Then tap install and go to the folder you saved the magical zip and install it.
Reboot and install magical manager as @snowrelyt said and you'll be ok.
Every info's you need can be found on the forum. If you're unsure, just ask again...
Good luck...

Thank you for this info... now I've gone down another rabbit hole after reading on different web sites
You say the bootloader must be unlocked - again after reading on different sites, there are 2 methods to determine if the bootloader is unlocked:
a) dial *#*#7378423#*#* (this did not work which upon reading said this method might now work)
b) C:\platform-tools>fastboot oem device-info
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
...
(bootloader) 'device-info' is not a supported oem command
(bootloader) See 'fastboot oem help'
FAILED (remote failure)
finished. total time: 0.007s
So 2 things; I read that if the bootloader is not unlocked and you need to unlock it, it will wipe your phone (obviously I can't have that) and secondly, the command to determine if the bootloader is unlocked did not seem to work for some reason on my PC (the 'fastboot devices' detected my phone when I ran it).

Well search how to boot into bootloader...
In bootloader you'll see this result:
Device is unlocked status code 3
If it says device locked... Well... You know what to do if you wish root...
Good luck...

Hey... You may flash TWRP recovery from bootloader using fastboot command. You can't root using stock recovery...
Download the latest TWRP from here and save it on your computer, preferably in the same folder you have ADB/fastboot:
https://dl.twrp.me/shamu/twrp-3.1.0-0-shamu.img
Just remove all security first before proceeding with the next steps (lockscreen scheme, password, pin. You can reenable them afterward. Just to avoid issues with twrp).
Your bootloader must be unlocked, otherwise unlock it first (you can find infos regarding bootloader unlock method in the general section of the Nexus 6 forum). Once/if the bootloader is unlocked, power down your device. Just press volume down and power button for a few seconds until you see a green Android laying down with it's belly opened...

Thanks so much! The bootloader was unlocked (I guess from an earlier root I performed using a Toolkit), and now I am rooted using Magisk.

Nice. Be careful what you do with your phone though. Since you seem to lack a bit of knowledge (no offence here). Read well before flashing anything... Avoid as much as possible the use of toolkits. I say this, since there are a lot of people bricking their device, unsure about what they did...
Cheers...

It's the universe telling you to stop using toolkits...
Seriously though, further up this thread there are quite good instructions on how to root without toolkits.

My problem has always been the command line. I've been reading up on terminal commands, and i might give it another try. A number of years ago, i bricked a Samsung Galaxy 3, and i've been gun shy ever since. I split my hard drive a while back, and if i can't figure out these commands, i'll go to the Windows 10 side and use Wug's toolkit.

As long as you keep your bootloader unlocked it's pretty difficult to brick a Nexus...
And to root your device you only really need to use two terminal commands. While in the bootloader (press and hold power + volume down to get there) run these commands from your computer (you can get adb and fastboot from here):
Code:
fastboot oem unlock
fastboot flash recovery <[I]insert_path_and_name_of_recovery_image_file_here[/I]>
The first one unlocks your bootloader. That will wipe your device though, so make sure to have a backup. If it's already unlocked, disregard....
The second one installs a custom recovery. Get the latest TWRP from here: https://twrp.me/motorola/motorolanexus6.html
After that you can boot to TWRP (from the bootloader), and flash the root zip of your choice.
Those are the basics. You've got lots more info in the stickies in the forum.

Semi working PRA-LX1C432

Hi !
I bought in January the nice P8 Lite 2017 and received a PRA-LX1C432 (dual sim europe no carrier).
It was with Android 7.0 and EMUI 5.0 and i wanted to root it.
I did it well, and was with the firmware PRA-LXA1C432B182 in stock and rooted with the tuto from this thread
https://forum.xda-developers.com/p8...ck-rom-huawei-prague-pra-xxxc432b182-t3727816
and uninstalled TWRP to put back stock recovery.
Later, I wanted to unroot my phone, and that's where things went wrong. I tried to do it with the superSU option and after a hard reset it was working and not rooted, but i'd still have the message "this phone can't be trust" so i tried to relock the bootloader and it did hard reset the phone again and now, i'm stuck with a phone that can send sms or go through the internet with LTE, but can't access fm, camera, google music, nfc is going on and off, calls don't work, etc... In dev options, Allow OEM unlock is greyed and I can't change anything. Phone is recognized by computer and I can acces memory of the phone.
I can hard reset it won't change, i ca also accessFastboot, or recovery or eRecovery, but in Fastboot mode it says "PHONE Unlock FRP Lock" and from my computer i can't do anything : if i try to flash twrp with fastboot command, i have the message "FAILED remote the command is not allowed", if i try to lock/unlock/relock bootloader it says "FAILED remote root type is risk".
Clearly, I don't know what to do. I'm used with rooting/unrooting smartphones from different brands (Samsung, LG, Sony, Huawei...), even though i'm far from being a master, and using Fastboot/ADB commands, but... I don't know.
If someone has any idea, I'm taking. I'm thinking about dload method but, of cooourse, I do NOT have a sdcard, so it's the last thing i would have tried from all i have seen on xda and elsewhere.
Thanks for reading and taking time to answer and help me, and sorry for not perfect english, i'm french but trying my best !

Run a eRecovery restore , it restore the entire smartphone to stock and also lock bootloader. Idk if this can solve your problems but i had ur same problem a days ago and i restored my phone enterely.

TWRP is not installed, and I can't flash it in any way. Fastboot says "FAILED (remote : command not allowed)" if I try flashing recovery or system or anything. It also says "FAILED (remote : root type is risk) if I try to lock/unlock/relock the bootloader.

Ok, I'm actually trying something. I plugged the phone into my computer, and HiSuite told there was an update available for my phone, so I just clicked on it. It's doing right now, I will edit my post after it has finished (for good or bad).
EDIT : Ok, si it did work ! My phone is now on PRA-LX1C432B194, everything is working, not rooted. I relocked the bootloader with Fastboot, the command did work (guess I can root it again if I need now). But I think I'll leave it like that ^^'
Allow OEM unlock isn't greyed anymore, I came back to the original state of my phone but with an update not (yet) available in my country, no more "Device can't be trusted" message. Like if nothing had ever happened (expect it will be written PHONE Relocked).
This phone is really sensitive, haha^^
But as anyway I made it
Thanks anyway for trying to help !

Bypass Pattern Lock in Honor 9 Lite without Data Loss

Dear friends,
my android device is Honor 9 Lite. Since I bought this phone, I was always able to get into the phone and access my data by using the touch sensor.
But nevertheless, I was forced to add a pattern lock as surrogate solution in case the touch sensor does not work for any reason.
Anyway, last week I hit on a serious problem! I did not know why the device dose not accept the first way (gaining access through fingerprint using the touch sensor) anymore.
It asks me all the time to enter the right pattern lock I set up 6 about months ago. And since I was not asked to enter the pattern lock before, unfortunately I just forgot it :crying:
Therefore, I cant access my device now and I do really have very important files and documents stored on the internal memory, which I do not want to lose by reset my device to factory settings and wiping all the data stored in the internal memory...
So I have searched the Internet - for long hours - for a proper solution that helps me to bypass the pattern lock without being forced to wipe my data.
But unfortunately, I could not find any effective way to gain access again to the internal storage of my phone.
One of the most important problems I hit on while searching the Internet was that there I could not find any way to enable USB Debugging in my locked device since I cannot access the settings....
Unlike some Samsung devices, it seems that there is no way to enter the known Download Mode in new honor devices. When I get to the Recovery Mode, I can see only three options, which are:
Reboot System now
Wipe data / factory reset
Wipe cache partition
The phone is still connected to my home network and my Gmail Account is still working on it. But I also could not find any way where my Gmail Account could be helpful in this case...
Is there any way to bypass the lock screen without losing data on this Honor device?
I hope you can help me to solve my problem and rescue my files...
Waiting for your suggestions :fingers-crossed:
Thank you very much in advance!
Kind regards

Perhaps you could help us to help you by telling us what version EMUI the phone is running?
Also can you enter fastboot mode and tell us what it says on that screen regarding lock(s) status?
If EMUI 8 you could probably flash TWRP to e-recovery partition, boot to it and use it to copy all internal data out and then reset the phone. But remember that the 9Lite employs encryption so even though you may get the data it will be of no use to you.

Dear Sparkrite,
thank you for your fast response !
I have attached two pictures which show both the EMUI Mode in addition to the Fastboot Mode on my Honor 9 Lite device...
I don´t quite know how to flash TWRP to e-recovery partition, since I cannot reach the device settings and thus I am not able to enable USB Debugging, which seems to be a necessary step to install or flash a new recovery environment on the device!
I also cannot enter the known recovery mode which we know on Samsung devices. I suppose that this has something to do with the operating system (EMUI) the phone is running.
Furthermore, I assume that the EMUI version which is installed on the device is EMUI 8.
I also would like to point out that the known Hisuite Software could´t connect to the device when I tried to connect the device to my Laptop using a USB cable.
Could you perhaps provide me with further information regarding flashing TWRP and gaining access to the data stored on the internal memory.
And is it possible to decrypt the internal data after extracting them from the internal memory?
A possible solution to my dilemma might be that I factory reset the phone and then try to recover the lost data using an Android Data Recovery Software. What would you say about following such a method?
I know that this will be very risky, but do you think that this would be a more effective and guaranteed way to rescue my data?
Thank you very much for your support!
Waiting for your response :good:
Sorry I could not upload the picture direclty from my computer, therefore I add here the links to the images in my album again:
Honor Lite 9 - EMUI Mode:

I don´t know why the images cannot be opened here. Sorry, this is my first experience on XDA-Developers
The EMUI Version is 8.
And on the fastboot screen there are two lines written in green:
The first line says: PHONE Locked
The second line says: FRP Lock
At the top of the screen I can see the following text:
Fastboot and Rescure Mode
Please connect USB cable to your computer and open HiSuite
Android reboot reason:
AP_S_COLDBOOT 0

Dear Sparkrite,
I have just searched the internet using the key words you have given to me.
It seems that the so called e-recovery is not a common issue for android users. I could barely find anything helpful in this field.
5 years ago, I was thrilled by working and solving problems of android devices. However, in the last 4 years time has changed and I have nearly stopped informing about such issues, since I had too much to do and I have forced too many obstacles with forced me to change my way of life.....
Moreover, my experiences with android devices were also done with Samsung devices. Except from this problem now, I had not worked with Honor devices in the past at all...
Anyway, I have just tried to flash a TWRP file on my Honor 9 Lite device using the known command window after entering the fastboot mode (of course without enabled USB Debugging). But it didn´t work and I have got the following error message:
PS D:\Android files\Honor 9 Lite\platform-tools>fastboot devices
FPMNW18924010946 fastboot
PS D:\Android files\Honor 9 Lite\platform-tools> fastboot flash recovery twrp_honor9_lite_0.1.img

sending 'recovery' (24954 KB)...
OKAY [ 0.640s]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: 0.650s
How can I flash TWRP on E-recovery without accessing the device settings? and what is the function of downgrading in this context?
What would you advice me to do?
I would be very thankful if you could make me aware on a good video or a helpful article for example, which can help me to get to my aim...
Thank you!

Well that command is doomed to fail for two very good reasons:-
1. Locked Bootloader.
2. The H9L using Oreo doe NOT have a 'recovery' partition as such.
The command to flash a custom recovery is :- 'fastboot flash recovery_ramdisk twrp.img'.
But as your BL is locked this will not work, however you can flash it to e-recovery using :-
'fastboot flash erecovery_ramdisk twrp.img'.
The advantage of downgrading (to at least B132 you have b144) is twofold:-
1. You could use HCU to get your BL code to unlock. (€4
1a. Or you could get your 'Slock' code to flash to 'unlock' your BL for free.
But unfortunately this would also wipe your phone.
2. Downgrading, using the Dload (Google it) method may well bypass the pattern unlock screen and/or fingerprint working again.
Edit:
Flash a working TWRP and come back to me when you can boot to it.
I may just have a workaround for you.

The locked bootloader on my phone seems to be the most important obstacle which prevents me from installing anything on the device
I have tried to flash the TWRP file to E-recovery using the command window in the file of platform-tools and a custom recovery for Honor 9 Lite. But this didn´t work either...
I always got the error message:
FAILED (remote: Command not allowed)
I know that this error occurs due to the locked bootloader, but I could not find any proper and effective way to unlock the bootloader on my honor device without access to my device settings....
I have also found out that my device belongs to the supported models on HCU-Client-Website. But as I have seen, the process of unlocking the bootloader using this method requires also a certain interaction with the device, which means that the internal files and settings of the phone must be accessible in order to get the code to unlock the bootloader...
Therefore, being unable to unlock the bootloader prevents me from flashing a TWRP. And being unable to unlock the bootloader prevents me also from downgrading the software and installing a custom rom on the device (see for example: https://forum.xda-developers.com/9-lite/development/kangvip-rom-emui-8-0-t3775904)
It is completely OK for me to buy HCU-tool to get the code to unlock the bootloader, if this can help me to gain access to the internal memory without data loss. But does this work in my case, without the ability to open the device.?! And if yes, how does this go or where can I find near instructions to achieve this mission?
And is there any way to downgrade the phone without unlocking the bootloader or flashing a custom recovery? If this was possible, then I would try to flash a custom recovery and delete the password file through a special file called aromafm and with the help of my SD-Card, which was a successful way five years ago when I was able to bypass the pattern lock on the device of my cousin without any data loss....
In the worst case, I would simply factory reset the phone and try to recover the important files using a good recovery software.....
I think, this may be the most appropriate method with minimal time exposure, since I must gird myself to start the new semester at the university...:good:
Waiting for your advice
Thank you once again :fingers-crossed::good:

As I said it is possible to flash TWRP to E-recovery even with a locked bootloader !!!
I have done it many times.
You will NOT unlock BL while on B144, without code.
HCU will NOT work with build numbers above 132.
ALL BL unlocking WILL re-set and wipe phone.
Downgrading using Dload method is possible with locked bootloader !!!
Search here:- https://pro-teammt.ru/online-firmware-database-ru/?firmware_model=lld-l31&firmware_page=0
Make sure it is a Dload ROM, it will say so within instructions in zip.
If you re-set phone, data WILL be gone, remember it is encrypted so no recovery.
My Advice is:-
Persevere with flashing TWRP to Erecovery.
Erecovery_ramdisk is NOT protected.
" fastboot flash erecovery_ramdisk twrp.img "

I have tried many times to flash TWRP to E-Recovery-Partition exactly as your have described in the last post, but I always got the same error message:
FAILED (remote: Command not allowed)
I have also tried to do the installation using different platforms and different TWRP files and sometimes with light changes in the code, but all my attempts failed...
My trials to downgrade the device to a version under 132 using my SD Card were also frustrating. I always got the same error, after the installation process reached 5%:
Software install failed!
Get help from: http://www.emui.com/emotiondownload.php?mod=restore
I tried to downgrade the device to the versions 8.0.0.0.127 and 8.0.0.0.131 and 8.0.0.0.129, which I downloaded from the website you have given to me. Also without success....
By the way, I could not find any instruction files in the zipped update files which I have downloaded from the website, therefore it was impossible for me to find out whether the downloaded Rom was compatible with the dload-method or not.
Also the program called "HuaweiUpdateExtractor", which I tried to use as an auxiliary means didn´t accept the UPDATE.APP and I always got the following error message:
ERECOVERY_VBMET.img: Invalid header crc - Expected: 33542 Got: 25244
It seems that there is no way out, right?
If there is a certain custom rom you can suggest for me, I would be very grateful.
Maybe I can succeed in flashing TWRP after downgrading the software installed. But I do not know if there is still a method that I didn´t try on this immune system....
Thank you in advanced!

I don't know what you are doing wrong.
It IS possible to flash TWRP to Erecovery as I have said many times before.
Try a different USB lead.
Try a different USB Port.
Try a different 'fastboot'/'ADB' version.
Try a different TWRP. (https://mega.nz/#!wotVWBQZ!ZO9DHD-HBMj-5LCxxW_74IYsDoSrVDeZsaQgMyIvuGQ)
Send me a screen shot of your command(s)
Send me a screenshot of your phone when you are trying to flash.

Dear Sparkite,
I have just tried all the alternative ways you suggested, unfortunately without success and I don´t know where the mistake in hiding
Again and again I hit on the same problem and I always got the same error message:
Command not allowed...
I have attached two pictures that show the fastboot screen of the device in addition to the commands I gave in the command window...
Thank you for your support!

My bad, I'm so sorry to have put you through all this, I forgot that I had previously flashed 'slock' to any H9L to enable flashing to Erecovery. Apologies.
However in order to obtain a slock file for your phone you will HAVE to downgrade to at least B132.
Get a Dload firmware from here:- https://androidhost.ru/
When you have successfully downgraded we can go about getting a 'slock' file for you.
Or if you like you could go here on Telegram and join up to get your 'slock' :-
