FAILED (remote: Command not allowed) - Honor 5C Questions & Answers

Hello friends
if i want to flash recovery or relock the device it tells me "FAILED (remote: Command not allowed)".
Till the nougat update it wasn't a problem, it worked like described in every guide.
I think my drivers are ok, no errors in device manager and on Marshmallow everything worked fine.
The big problem is my home banking app detects the unlocked bootloader and stops working
so i need to either lock my device or root it.
Here are some data may they will help
At fastboot

Hi MHN.1515,
and thanks for your participation.
this is exactly what i did.
I went back to the stock image "Honor 5C stock ROM images (latest: B102) NEM-L51" from PaulOBrien on MoDaCo. (Thank you for providing the image at this place)
Then i flashed NEM-L51C432B130 from here. (Thanks to Druger too) In this process the bootloader got locked again.
From there i updated to Nougat again, the good things are my phone is locked so i can use my homebanking app
and in developer options i can turn the Unlocking bootloader switch to on or off as is want to root it again one day.
So i hope i described the process well so it can help people with the same problem.
Greetings
Max
Btw. next time i need a better backup strategy, or at least a backup strategy

In this case I am unable to help you, but you can use dc-unlocker paid service.
It is here:
https://www.dc-unlocker.com/huawei-android-phone-frp-unlock
Sorry I never used it so can't give more information, you have a look and decide.
@Snober
you have now FRP-Lock ?
have you twrp/backup from last state (before install kangvip)
then test twrp/restore and look if phone work FRP=unlock
it is better if you need help - give more info : what is your build ? LLD-xxxxxxxx / what is delivered OS ( first delivered "7.xx", current "8.xx")

No sir i don't have backup of last state. And i can't go to twrp as i installed stock recovery
My build is 8.0.0142 c675 indian version
Now there is another problem now. I searched for solutions and got the answer as to relock bootloader. Then i relocked it with fastboot cammand. Now the phone is bricked and restarting to erecovery after honor logo. Currently status is phone relocled and frp lock in fastboot.
Please help
@Snober
sorry, now you have big problem !
Relock Bootloader is the greatest Bull**** by phones ! (my opinion !) if you relock bootloader WITH damage-rom you have a "damage-phone" !!!
please search "repair bootloop with bootlooder relock".
for future if your phone again work
- unlock bootloader AND let it open
- download your build FULL-Update (now you have backup for repair - if needed)
this 2 point's is very important
i think you have 1 chance to self-repair : search "recovery_ramdisk_BKL-L04_nocheck.img"
but - this is no simple. you must read and understand before you do ! I DONT KNOW if this work for you !!!
@JamesBott
Isn't it possible to unlock the bootloader again after relocking?
@BS4388
usually yes, but if you relock bootloader WITH damage-rom you have a "damage-phone" !!!
that's the point. if user install dev-rom and this work not 100% good AND then relock bootloader ...
if now bootloader locked - you need "fastboot flash oem unlock your-unlock-code"
if you have FRP-lock you dont can "fastboot flash xyz"
my friend have many "help me" from other user with this problem
he found the way with "recovery_ramdisk_BKL-L04_nocheck.img" and say - this work only if on phone twrp installed BEFORE error AND boot to twrp work
usually you can bootloder unlock and relock with your-unlock-code many (not once only)

Well, I think @Snober can still revive his H9L by flashing a stock firmware using a paid service such as dc-unlocker bypassing the frp lock.
@BS4388
i dont know if dc-unlocker work with frp lock.
but i think it is a test worth - only it cost 15€ (ca. 15$) (if not work only 15€ lost - new phone cost 230€ [in germany])
i think if it's not work, dc-unlocker rewrite money to user-account. but my last dc-unlocker use a little time before now
I am sending my phone to friend as there is no service center in my location .
Should I send .
Can the phone be warranty as my phone status in fastboot is phone relocked and frp lock .
Will they detect the phone was unlocked or something like that . I mean will any problems comes . ?
Got My phone repaired in service center for free. They didn't see as the phone was in relocked state. So happy ?
this is very very good for you
BEFORE you any things do in future with your phone - YOU NEED FULL-UPDATE on your PC

For future reference: Stock ROM appears to require a network connection in order to enable FRP, so, connect with WiFi and it should become touchable.

Hm...
So what you're saying is that there are no Nokia 7 Plus' that have an unlockable bootloader? Or, to put it another way, do all Nokia 7 Plus' have the option "OEM unlocking" set to off? With no way of switching it on?
Or is there a way to switch it on?
I have booted into download mode, and fastboot flashing unlock, but it returns 0 or failed to unlock.
oh wait... I saw your other post: https://forum.xda-developers.com/showpost.php?p=78764676&postcount=3 In reference to the first item, the website is hikaricalyx?

Ok... so... for Nokia 7 Plus...
I need to download ntools, HMD rom for version 8, android 8, adb/fastboot.
Then downgrade to version 8.
Flash HMD version 8 rom. (But how do I flash when it's still locked? Or does downgrading to 8 allow the option oem unlocking to be turned on?)
Unlock bootloader.
Use magisk to get root.
Is that the steps? Or am I missing something?
Search for techmaesto.
techmesto dot com/how-to-downgrade-nokia-7-plus-from-stable-pie-to-stable-oreo/
I'm using that guide, and I get up to the part where I update via SD card. But it says that the update package is older than the current build and downgrade not allowed.
What can be done about this?
Anyone know if Nokia will ever allow the bootloader to be unlocked?

First, keep your code (on several places, even printed on the paper), it is good for relocking/unlocking (you never know, some actions may lock the Bootloader back) for the lifetime of your phone.
You don't want to go buying the same thing again
Assuming you know how to enable OEM Unlock in Developer's menu and you are a little familiar with Fastboot, it is simple to unlock the Bootloader
Code:
fastboot oem unlock <your code>
If not familiar, and if not clear as below, search on Google how to:
- enable Developer menu by clicking 7 times to the build number in Settings/About
- enable OEM unlock in Developer menu
- install "Minimal ADB and Fastboot" to Windoze (smallest, self containing package with everything for ADB and Fastboot)
- reboot to Fastboot: keep pressing Vol-, then Pow button
Unlocking Bootloader triggers hard-reset, wiping also Internal memory. Backup as much as you can - use Google account, HiSuite, WA own chat backup, copy DCIM to PC, Contacts can be exported to vcard file, etc
Rebranding to AL10c00, upgrading to b540 Oreo, applying the neccesary Network patch to make SiM card(s) working - all is in deep details explained in the OP posts:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
Read two times before you start, and keep the instructions opened on the PC while doing - wrong moves can cause (soft) bricks

Thank you, Brother, I have done all procedure and my device is now at Oreo, Build EVA-AL10 8.0.0.540(C00).
After doing all the required steps I have flashed Huawei's Official Recovery and enabled OTA, after that I have received an OTA update of 3 MB, Should I install the update or not?

It is safe, just some Patch02 (never found exactly what for).
If you don't mind, you can skip (you can disable OTA - see in OP)
If you go for, you must first flash back the stock Recovery, hence not having TWRP. Not sure anymore, maybe also stock Ramdisk, hence not Magisk
Patch02 will not affect Network Patch or Face Unlock (cool add-on, see OP)
If you didn't apply Network patch yet, etc - then accept Patch02 and continue with OP instructions.
If you already rooted by Magisk, then don't bother with Patch02, too much trouble preparing clean sheet for OTA and rooting again

I have already applied Network Patch, See my both SIM is working.
Right now I don’t need Root so I'm skipping Magisk.

I'm from Bangladesh, some Operator in our country introduced VoLTE.
It seems there is an option called VoLTE after upgrade to Oreo. Is it really works?

Nope, VoLTE does not work.
Everything else, like location sharing and Ok Google are fixed with Network patch, but not VoLTE.
The guy who did the whole majestic work went tired (although he believed he was close to fix VoLTE) and gave up. Later he upgraded to newer Huawei devices with Pie, etc, and eventually moved away from XDA

It's not possible to remove the warning on booting "Your device has been unlocked and can't be trusted" (IMO, it must have been commented somewhere in the OP) - that's price for the unlocked Bootloader.
But you must not relock Bootloader - it would trigger Hard reset, removing Network patch (even worse, it could also cause soft brick if TWRP or Magisk are installed)

Pixel 5 Android 12 Developer Preview 3 OTA Sideload failed at 94% and now it says "Can't find valid operating system. The device will not start."

I tried to install Android 12 Developer Preview 3 on my Pixel 5 via OTA Sideload but it failed at 94% with the message 'adb: failed to read command: No error' on cmd and 'Install from ADB completed with status 0' on phone.
After this when I try to boot, I get the following message: 'Can't find valid operating system. The device will not start.' (attached image)
I'm able to access the bootloader but when I tried going into recovery mode through the bootloader, it shows the same message: 'Can't find valid operating system. The device will not start.'
Seems like the recovery is corrupted as well.
Unfortunately I had not enabled OEM unlocking in the developer options before trying to install the Developer Preview, which is now not letting me unlock the bootloader.
Please help me fix the issue or help me find a way to unlock the bootloader without enabling OEM unlock.
Thanks in advance.
I had the same thing happen to me just now. Have you managed to figure anything out?
Nothing from my side, since bootloader is locked I can't flash the system image and I can't unlock bootloader because my OEM unlock is turned off in developer settings and the Recovery and Rescue mode are also corrupted.
I contacted Google support and their only solution was to bring it in for service as my device is still under warranty.
I'm in the same boat here with a Pixel 4a 5G. Got to 94%.
First time I've experienced an issue while sideloading. . .
Contacted google support and they are shipping me a refurbed replacement... disappointed, to say the least.
Not sure what to make of this, it's developer preview and now beta. Issues will possibly occur and it warns you of such.
**Possible Fix**
I would believe this might be due to the boot_a & boot_b when trying other custom ROMs or OTA updates.
I used the fastboot/ADB files from the lineageOS ROM page and used the command: fastboot flashing unlock
to unlock the bootloader again, this then allowed me to go back into the rescue mode and use googles online image reinstall and got me back onto the stock ROM. Hope this helps some people

As an additional this let me get my phone back to loading the custom ROM I was on, to then reenable debugging mode, I then rebooted back into fastboot mode and used Googles online factory restore mode to flash stock ROM back on and I was back up and running

I used the fastboot/ADB files from the lineageOS ROM page and used the command: fastboot flashing unlock
to unlock the bootloader again, this then allowed me to go back into the rescue mode and use googles online image reinstall and got me back onto the stock ROM. Hope this helps some people

As I had mentioned earlier: I had NOT enabled OEM unlocking in the developer options before trying to install the Developer Preview.
So this method does not work for me. It will be helpful if I can find a way to force unlock the bootloader somehow.
Thank you for your reply. Hope your method helps someone else resolve their issue.

This might not work but have you tried plugging the phone into the computer using the pixel online factory recovery and tried the first step of the process which is a prompt to unlock the boatloader?

I'm going to state what should be obvious here - you should not attempt to use pre-release firmware with a locked bootloader, because you will ne severely limited on what you can do to recover if something goes wrong.
Unlocking the bootloader is not possible if OEM Unlocking is not enabled.

What exactly are you referring to? The Android Flash Tool requires an unlocked bootloader to start with, and does not unlock the bootloader itself.

Are you not aware of the Google online tool for their Pixel phones? https://pixelrepair.withgoogle.com/carrier_selection
This has additional flashing options within the 'online' version of fastboot/adb, and found that when trying locally downloaded adb/fastboot it didnt work. But when using the online version it allowed me to unlock the phones boatloader.

I am aware. However, this tool does not function like adb and is not meant for flashing factory images like the Android Flash Tool is. The Pixel Repair Tool works specifically from Rescue Mode.

It sounds like your Platform Tools may be out of date. Current version is 31.0.3, Aug '21.

My rog 3 tencent version is not unlocking bootloader, bootloader is failed to unlock your device plz help me

My rog 3 tencent version is not unlocking bootloader, bootloader is failed to unlock your device plz help me
How did you attempt to do it? Steps please.
Same issue here. Previously I was just downloading the Unlock Device app here and running it. (I already had developer options enabled) and the device would reboot but not do anything (I reckon I tried 10+ times). Since then I formatted the device and tried again and got the same results so I set the device backup normally today (running build 18.0410.2108.158) and tried it again (with and without developer options enabled as I forgot to check) and I just get a standard error message saying it couldn't unlock my device and to try again later. Same result multiple times. I don't see any option for OEM unlocking in Dev options which I see some people mention. I'm updating to the latest OS I can see in the link I provided and I will try again after installing that.

Or not as it fails saying System update fails immediately after I select the update file and press go. :/

Hello
Your phone has already been unlocked earlier and has the flag removed. Someone blocked it again for sale.
So you won't do anything with Asus tools.
I recommend the EDL mode
Regards
