Can't relock bootloader: bad key/unsigned boot.img message

Hi,
I'm new to Z2 play ROM/TWRP things and here's my issue on a XT 1710-01 (on retca channel):
After unlocking my bootloader, I've installed TWRP 64 bits and did a backup before doing anything else, but for whatever reason, restoring it didn't work. I just thought then that I could re-flash the retail stock ROM available at https://mirrors.lolinet.com/firmware/moto/albus/official/RETAIL/ , which worked fine (phone boots fine, works fine and is still on retca channel, etc.), except that now, I'm unable to re-lock the bootloader, as I get a message like "signed boot.img required" (or something alike) on "fastboot oem lock" command.
I also get the "bad key" message on the unlock warning at boot time (see attached).
Here are the commands I used to reflash the stock ROM:
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
Now, I'm just wondering if I missed something or is it just that the stock ROM I reflashed is not the good one (or just unsigned) . Any help would be appreciate.
Thanks.

Need official signed by Moto image. Not available from any official source unfortunately. I have a same request to lock a bootloader.

it's very important to ask how your parachute Works before you jump off the plane

@KirMit Thanks for the follow-up.
Do you know if it would be an option for me to try to find a complete ROM/backup made by someone with the exact same model (so presumably, with the signed boot.img), flash/restore this backup on my unit and then try to relock the bootloader?

I have the same problem. Cannot find a signed boot.img
If anyone can think of a solution I would be totally interested in hearing about it.
I can live with this phone with the bootloader unlocked, but I may need to sell it, so I need to get rid of that warning screen.

You can get rid of the warning screen, but you can't get rid of the N/A-Bad Key sign, so you must make your own boot logo (meant to cover those nasty letters with a white background) and ADB flash it as logo.bin... that's if you don't have TWRP recovery; in such case you can use a flashable zip for that matter.

Doesn't work on my Z2p. My oem unlock is always greyed out even after trying the instructions in this video with 3 different firmwares.
For anyone who doesn't understand what's going on in the video.
1)flash the firmware.
2)flash twrp, backup boot & system.
3) restore boot and system and reboot
4) go to developer options and, enable oem unlocking
5) return to bootloader and run the lock bootloader bat file.
6)done your locked.
Or if like in my case, it does not work, oem unlocking is still greyed out.

I managed to ungrey oem unlocking but, only by flashing magisk. Somehow magisk ungreys oem unlock? Unfortunately, we cannot lock bootloader with magisk installed. Once magisk is uninstalled, oem unlocking is greyed out again?
I think I know how to get around this, adb pull boot.img that magisk has modified. Full unroot magisk, preferably with magisk uninstall zip. Then fastboot flash the patched boot image and run bootloader lock with the OEM unlock switch set.
---------- Post added at 10:32 PM ---------- Previous post was at 09:49 PM ----------
And I am locked, it worked. I now know how to lock my bootloader even when the video guide above fails to remove the greyed out oem switch.
1)flash the firmware.
2)flash twrp, backup boot & system.
3) restore boot and system
4)flash magisk and reboot
6) back up boot.img to pc
7) flash magisk uninstall zip
8)fastboot flash stock recovery
9) fastboot flash magisk modified boot
10)boot device and enable oem unlocking
11) reboot to bootloader and run bootloader lock bat file
11) oem locked!
By the way, easiest way to back up boot is use the app "partition backup & restore". Be sure to change the setting to save as img and not archive.

Yes! This!
I've never been able to go back to stock and relocking the bootloader because the OEM Unlock was always greyed out. Using the patched boot.img, as @Cupcake 1.5 explains allowed me to lock my bootloader again.
Thank you!

Hi all, ok i'm late unfortunately can you help me ? i have the boot magisk signed and key is ok. But when i'm reflashing recovery stock, there is also a bad key.
So there is still the warning at startup, i think this is due to this issue

[ROOT] How to properly root the P20 lite

Even without a custom recovery like TWRP you can get Magisk on your phone.
To do this you need to manually patch the stock boot image and flash that to your boot partition.
However, I've done all of this and with a few steps you'll be rooted.
There's a more detailed guide below.
1) Get bootloader unlock code here
2) Enable "OEM Unlocking", boot into fastboot and type: "fastboot oem unlock your-unlock-code"
3) Download patched ramdisk image here and put it in fastboot directory.
4) Reboot into fastboot and type: "fastboot flash ramdisk patched_ramdisk.img"
(Optional) 5) Flash this to go back to stock ramdisk
[Detailed Guide]
First off, you need an unlocked bootloader. To do this, you need a special code from Huawei, you can request this here:
https://emui.huawei.com/en/plugin.php?id=unlock
With this code, and having "OEM unlocking" enabled in debugger settings, boot in fastboot mode.
Afterwards, open fastboot console and type: "fastboot oem unlock your-unlock-code"
Your device will now reboot.
Now reboot your device back into fastboot mode and open a fastboot console once more.
Download this patched ramdisk partition and place it in the same folder as your fastboot executable.
http://www.mediafire.com/file/9yfz6w9e8q7j5u2/patched_ramdisk.img
Now simply type in the console: "fastboot flash ramdisk patched_ramdisk.img".
Reboot your phone and it is rooted!
Download Magisk Manager to update/configure Magisk.
[REMOVE ROOT]
To remove the root, simply flash this original ramdisk partition, the same way as above. You can also relock the bootloader if wanted.
http://www.mediafire.com/file/4d6w2labc6cmh2o/original_ramdisk.img

WORKS IN ANE-AL00 china model??

When I'm trying to install the patched ramdisk with "fastboot flash ramdisk patched_ramdisk.img" it says "cannot load patched_ramdisk.img".
What's the exactly directory?

@RogerXIII, from which build did you patched ramdisk?

I think you mean the directory:
On your computer you have the file "fastboot" that you use for sending fastboot commands to your phone, put the .img file in yhe same folder as that program. If you don't know where it is located, you can download the platform-tools files separately and use those.

Thank you worked very well. I need twrp but i cant find or Build compatibility with p20 do you find any way to get it work?

1) Get bootloader unlock code here
this is giving me a 404 error...

In which compilation (build) did you use this root?

Just got root on ANE-LX1 successfully. Tell me please, should this metod pass SafetyNet or not?

Rooted my ANE-XL3 just fine.

Hi. Huawei P20 lite ANE-LX1 8.0.0.111(C432).
Asking for some advice. Having read several how to guide to root, installed adb on Linux, connected, backup ok, patched ram disk, original ram disk and so on and so on, Running in circles about UNLOCK CODE: OR getting a 404 eng/Chinese, Or logging at Huawei and getting a US page for honor 7/10. Cannot get the unlock page to fill the formulary, although having all necessary info, IMEI, Product ID etc. My region is PT. Request advice, considering returning the phone wich is not so bad at benchmarks... Thank you. Congrats

I payed 5 usd at dc-unlocker and unlocked my bootloader in about 20 minutes. I followed this guide:
https://forum.xda-developers.com/honor-7/general/bl-unlock-dc-unlocker-t3318738

Just got an OTA: ANE-LX1 8.0.0.105(C10). My device OS ver.: ANE-LX1 8.0.0.102(C10). Please tell me, should I apply it? What will happen with root? Will I need to reflash ramdisk after update?

Can someone tell me where to unlock the bootloader? The link gives me only a 404 page

[BRICKED] Stuck in android 8.1 bootloop

I just bricked my phone :crying: :crying:
I wanna get back to the official rom, after trying android P (without make it work).
(the rom is from http://en.miui.com/download-354.html)
But I run the wrong script and take the flash_all_lock.img
And my device is stuck on android 8.1 bootloop (It boot, but i get an animated line loop ...)
Any ideas or tricks before i get it back to warranty ?
Thanks

Unlock bootloader and flash again. You can find a guide to unlock bootloader at the beginning of this guide.

Have you tried to switch the active slot?
Try if it boots using
fastboot set_active a
or
fastboot set_active b
If not working, can you enter recovery (power on with Volume up button pressed)?
If you can enter recovery, hold down the power button for 3-5 seconds and then press and release the Volume up button, to make commands appear. Then your only hope is to install the OTA update zip from there (copy the OTA in a microSD card, there is a thread where you can find the link to the OTA zip).
In my opinion, "OEM unlocking" in developer options MUST be always keep active, because incidents like this could happen, and because even without modding, an OTA could go wrong resulting in your same situation.
I was in your same situation (OEM unlocking disabled and then I locked bootloader with a custom ROM installed) with a Nexus 5X.
I don't remember well how I fixed it, but I remember entering in Qualcomm download mode (should be the same EDL mode) and loading a file found after many hours of research in strange forums and sites.

Have you sideloaded the zip? I think it's better to copy the OTA zip to microSD than ADB sideload.

There should be only two methods for entering EDL:
1- request authorization in en.miui.com forum. Sometimes the admins accept requests to give an account one EDL flash permission (but I don't know if it works with AndroidOne devices).
2- finding the test point in the phone's motherboard.

Hi guys,
i tried to install this twrp but it doesnt work...

so nothing to do....but right now my MI A2 lite not boot.
i try again to check my partition but this time i have no replay.
i have unlocked bootloader but i cant go to recovery and i cant boot!!

I HAVE THE SAME PROBLEM
everything you said is completely simillar to mine. Can someone help us? Or did you already fix it? Please help me i need my phone working.

I have same problem fastboot flash but after that, it started to reboot automatically. The phone was automatically turning off and on. I again did a "clean all and lock" via miflash tool but still now, no result!
I can boot into recovery without having any problem. But when I boo to setup country date....etc, it starts its auto rebooting process,

How to unbrick?
Hey guys. I bricked my Mi2 Lite as well. Is there any step by step way to unbrick?

had the same problem, was stuck in the bootloop even after I flashed img with MiFlash! NOTE: MY BOOTLOADER WAS UNLOCKED!!! (LUCKLY I DID NOT TRIED FLASH ALL AND UNLOCK!)
headed to this thread
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
did not work, I get error saying FAILED
but after i used
Code:
fastboot oem edl
I went to MiFlash and used "Clean all" option (again note DON'T use "Clean all and lock"!!!). It took around 5 minutes to flash and my notif. light blinked whole the time. After it say "Success" I was able to normaly boot the phone again

Find "Mi A2 Lite toolkit V 1.0.4.2" and use it to flash stock 8.1, it will do all the magic with a few clicks, just don't interrupt it until your phone restarts and you get the "Welcome" screen. After you can do the upgrade to Pie via OTA.

Hi, where i can find MI A2 Lite Tool Kit? i open my device and i can put in EDL mode., my computer detect my pone in EDL mode, but i can not know do.

Hi all,
I also had same problem and I just resolve it.
My phone was in bootloop mode after stock rom flashing...
You don't need apply "fastboot oem edl" !
Just be sure your device is unlocked.
Download first stock rom (V9.6.4.0.ODLMIFF Firmware for Mi A2 Lite). If you flash last ROM, it don't work.
Flash it with XiaoMiFlash tool (don't forget to enable "Clean All") in bottom of the tool.
After reboot, you can apply OTA updates.
Enjoy !

DT2W July update

Is there any way to enable back Double Tap to Wake (DT2W), after last update my phone lost this function and in the settings app there is no option for this. Is there any easy way to bring back my phone to June update or to enable dt2w in the last update somehow?

I'm growing tired of xiaomi for being such incompetent in all things related to android one, i kept the phone without root until this day but i really need dt2w, I remember seeing a thread long ago that there was a line in the build.prop to enable or disable it, I'll try to find it and see if it works

Ya, I saw that before. I open the generic.kl file see, the key is not commented out. I also download SetEdit app, the dt2w property is already set to 1.

I have theory, I don't know did these updates update or change somehow the kernel but I think the last one had done exactly that. IMHO loadable module or driver responsible for dt2w had been "forgotten" to be built into the kernel.

You can download the 10.0.10.0 image from [FASTBOOT] [daisy] Xiaomi Mi A2 Lite FASTBOOT Images
Then follow steps in How to Flash Fastboot Firmware with Miflash Tool
If you doing this for the first time, you need to learn a lot of things and do a lot of research.
If not careful you could brick your phone and do not know how to get out from bootloop
I stuck in bootloop when flash for the first time, don't know what happened, later found out I just need to switch to another partition.

fastboot getvar current-slot

On the screen I get: your device is corrupted and cannot be trusted and cannot reboot

Simply disable Developer options and the any settings you altered there will revert to baseline.
If that doesn't get it then it's not Developer options...

We can't really help you until you confirm what you did to get it in this state in the first place?
Did you install the OxygenOS 12 Developer Preview?
Did you try rooting by replacing the stock boot.img?
Please confirm what caused this in the first place as changing something in the developer settings alone would not cause this.

OK, If you used DSU to try out the Android 12 Developer Preview your bootloader needs to be unlocked, try running :
fastboot oem unlock
Bear in mind it will wipe the phone though, then reboot back into the Android 11 rom, set it up and THEN try DSU.
You need to have previously allowed bootloader unlocking in your developer options (see below)

It is good? Should I keep waiting? (I don't know really what to do, I don't know even if the device got the command from the pc)

If you're stuck on bootloader only you can try running these commands in fastboot :
fastboot -w
fastboot --set-active=a
fastboot reboot
If the phone does not boot properly then try these :
fastboot -w
fastboot --set-active=b
fastboot reboot
"fastboot -w" wipes your userdata. The "fastboot --set-active" command tells the phone which A/B slot you want to use, "fastboot reboot" is the command to restart the phone.
If you just keep getting sent back to fastboot and it won't boot then you're likely going to have to use the MSM tool to restore the phone to factory settings.

Really really thank you
I have tried all 4 commands (-w, --setactive=a/b and reboot)
all of them after I turn off and back on my phone show me the bootloader
can you send me a link to how I use the MSM tool to restore the phone to factory settings?

You have a LE2120 so there is no msm package publicly available yet.
In the screenshots, it shows that your fastboot drivers are not installed. Did you fix that first? The command take less than a second to run.

You can download and take the flashall.bat from this conversion guide and download your version of oneplus9pro rom to your pc then use payload dumper to extract all images, then place the flashall.bat in the same folder as all your files you dumped then plug ur phone in(while it is on bootloader screen) and double click the flashall.bat

This is the link to the op's zip(he created for the thread for converting tmobile variants to EU). . Click the link and download the zip, put it on your pc, then u have to extract all files. The flashall.bat is one off the files in that zip.. Then Google search the Chinese version of tue latest op9pro OS11.. Get it on your pc. U have to use payload dumper(which you will need to search android get on ur pc, extracted as well). Then once u get payload dumper ready, and ur rom, take them payload.bin from ur rom folder and put it in the payload input folder. Then double click the payload.bin and it will slowly extract all your files and put them into the payload output folder. Once it's done take the flashall.bat and put it in there. Then ur ready to plug ur phone in(in bootloader mode) and double click the flashall.bat

And honestly, you could prob just download the zip I mentioned, the first one just to get the flashall.bat, and just extract it, plug ur phone in(in bootloader mode) and click the flashall.bat. It would put the EU version of OS on your phone. Use cld then use the loavl update in system settings to switch to ur variant after. Much easier.
