[SOLVED-ish] Bootloader Relock FAILED - Honor 7 Q&A, Help & Troubleshooting

I've been trying to relock my bootloader all afternoon...
fastboot oem relock 1234567890987654​
Why? I was on B121 with unlocked bootloader, TWRP and SU. My intention was to flash stock recovery, relock and update to B140.
After a lot of experimenting, flashing, re-flashing, wiping etc. I cannot relock the bootloader. Even with a complete system flash and wipe of data. It fails with
Code:
FAILED (remote: root type is risk)
Does anyone know if there's a tamper flag, or similar
EDIT - I sort of solved it myself in post #7

I think that the command is: fastboot oem lock.
from your description I don't see the rationale on locking bootloader. Be very careful, with unlocked bootloader you can make almost any mistake and find the solution but playing with locked bootloader is a totally different ball game.

Not on these. That the first thing I tried. That gives
Code:
FAILED (remote: Command not allowed)
Which is essentially "command not found", as you can pass it any garbage and that's what it gives back.
As I see it, you can't install updates with an unlocked bootloader (unless I'm wrong, or there is something desperately wrong with my phone). With no custom roms (at the moment) this is all we have
EDIT:
Looks like I was wrong about updates on unlocked bootloader. I went back to B100 (UK) then back up to B121

Have you succeed to relock bootloader? In case of warranty need locked bootloader is a must thing?

I haven't retried yet. I was still in my 14 day return period and was undecided if I was going to keep the phone

Questions:
What model of Huawei Honor 7 do you have? (Settings -> About Phone -> Model Number)
Have you tried it on B100?
Have you tried it on B140?
Have you tried "oem lock" instead of "oem relock"?
Note: Always mention your model number in your thread title and description. Not all different models behave the same and not all updates give the same error message.
Thank you for opening this thread. We hope to read your answers on the above questions to help you.

I have the EU Version PLK-L01 16GB
..and yes I had, see my second post - lock doesn't seem to be a valid Huawei boot-loader command.
I've had a busy and incredibly boring time trying to sort this out.. Somehow, I re-locked :victory:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Unfortunately from the point of view of returning the device to Huawei, Re-locked is not the same as Locked, but it's all I have found.
After TWRP format:
Code:
sudo fastboot oem relock 1111111111111111
...
[B][COLOR="Red"]FAILED (remote: images signature check fail)[/COLOR][/B]
finished. total time: 1.048s
After B100 Downgrade:
Code:
fastboot oem relock 1111111111111111
...
[B][COLOR="Red"]FAILED (remote: root type is risk)[/COLOR][/B]
finished. total time: 0.970s
I re-flashed the UserData image from B100, after booting up I got this:
After UserDate Wipe:
Code:
fastboot oem relock 1111111111111111
...
OKAY [ 1.985s]
finished. total time: 1.985s
fastboot oem get-bootinfo
...
(bootloader) [COLOR="Green"]relocked[/COLOR]
OKAY [ 0.000s]
finished. total time: 0.000s
So basically, I re-locked with a completely fresh, untouched system and a "factory" wiped data partition.
Obviously I have unlocked again and gone back to B140. If someone else want to experiment, feel free to post your results. I'm done with this :silly:

Re-lock your bootloader successfully
Re-lock your Honor 7(PLK-L01)'s bootloader successfully
No matter on which version you are and on which recovery, follow the steps:
1. Extract the B100 "UPDATE.APP" using this tool. Credit goes to its maker. If you wanna make flashable zip from "UPDATE.APP" then use the attached "Profiles.xml" file for HuaweiUpdate Extractor, me and @kenshiwara has added Honor 7 in the list.
2. Now flash "boot.img", "recovery.img", "cache.img", "cust.img", "system.img", "userdata.img" from the extracted B100 "UPDATE.APP" by executing following commands in "Command Prompt"
Make sure you are in the same folder where all these files are then "Right click" inside the folder by holding down "Shift", then select "Open command window here".
For "boot.img"
Code:
fastboot flash boot boot.img
For "recovery.img"
Code:
fastboot flash recovery recovery.img
For "system.img"
Code:
fastboot flash system system.img
For "cache.img"
Code:
fastboot flash cache cache.img
For "cust.img"
Code:
fastboot flash cust cust.img
For "userdata.img"
Code:
fastboot flash userdata userdata.img
Now reboot your device by executing this command
Code:
fastboot reboot
3. Setup your device, then place B100's "UPDATE.APP" in your external SDCARD in "/dload" folder.
4. Now, switch off your device and press the three button combo to flash the B100 "UPDATE.APP", the three button combo is "Vol. Up", "Vol. Down" and "Power Button" press these three simultaneously to flash the B100 "UPDATE.APP".
5. After your device reboots and after you are done setting it up, go to "Settings > Backup & Reset", then select "Factory data reset", tick "Internal Storage" and press "Reset Phone".
6. Again after rebooting, switch off your device then by pressing "Vol. Down" button connect your device with PC.
7. Now, you'll be in "Fastboot&RescueMode" and your device status will be "Phone Unlocked".
8. Execute the following command to relock your device.
Code:
fastboot oem relock *16 digit unlock code*
9. Now, you'll see that your device status is changed to "Phone relocked".
So, you just relocked your Honor 7.

So basically what I said then

I think you just flashed "userdata.img" of B100 which is not good as it broke your "/userdata" partition, but yea basically that

i'm not well
my humble apologies @DigiGoon

I have try "fastboot oem relock *my code*" and it works. But i had changed nothing on my phone. it was just unlocked.
no root; no TWRP; no other updates
maybe this was the reason why.

---

I have unlocked my phone.
I'm now on B140.
With a unlocked phone, do I still get updates from Huawei anymore?

---

You will receive updates but do not install them!!!! If you don't listen to me your device will be caught in bootloop
