pls guys help me
1. enable developer option
2. enable oem unlock
3. get unlock code from motorola website
4. unlock via fastboot
Sorry, misread. I think you want to unlock BL.
Did you read XDA rules...? Did you search...?
There is already a thread for ReLock issue..
As you will read,
You can't downgrade bootloader if once updated...
Don't Mess with bootloader unless want a brick....
According to my views, there are no benefits for ReLocking unless want to sell phone and make buyer fool... LoL...
I unlcoked Moto G5 Plus bootloader few days back, but when yesterday night i was trying to lock the bootloader by flashing the available stock roms on the internet which are NPN25.137-33 and NPN25.137-35 i tried with both but it still asks for "Signed boot and/or oem images" to lock the bootloadewr again.
If any developer/person has some solution, please tell us as many of the users are facing the same problems.
My Moto X Pure (XT1575) is currently unlocked on stock status code 3. I need a signed boot.img to relock the bootloader, however all the stock images I find always returns with Prevalidation Failed. This error only shows up after I've put in "fastboot oem lock begin", but otherwise any boot.img flashes fine. I need to be able to relock the bootloader so if you have a signed boot.img, post a link. All the other files flash fine though.
Yeah, we know... if you are on build MPHS24.49-18-16 (December 2016 security patch) or ever took that update at any time that was release about February of this year, there is no way to relock the bootloader, period. If you never took that update there is some chance of performing it, but I am guessing this isn't the case.
In order to relock, you must flash a complete, signed image to the device in it's entirety... and since downgrading is not supported (not in it's entirety anyway) the only way to do that is with a complete image that is the same or never version, and we do not have that at this time. TBH, we don't know if we ever will get a newer version at all. The source for these images has said that there is still some "possibility" of getting some images, but nothing has been seen new in several months for any Moto device (not just ours).
i try to flash stock rom on my moto g5 plus but fastboot flash partition gpt.bin got error so i skiped gpt.bin and flash other files via rsd lite now i want to lock the bootloader but when i tried it show still require signed img file.any one help me
You need a signed image to relock the bootloader, per the message...
I don't believe we have signed BL files, but I could be wrong.
I wanted to relock the bootloader of my Moto G4 Plus as now I'm in no need of root now. And even want to remove the logo which says my bootloader is unlocked.. I used the code but it is not working still pls help me out
i think you are in the wrong section but nvm. for removing the annoying boot logo you can flash the logo bin
Code:
fastboot flash logo logo.bin
in fastboot mode where "logo.bin" is the filename.bin. you can find the logos at this link
https://forum.xda-developers.com/moto-g4-plus/themes/customized-logo-t3451349
or if you want some more cooler ones just search around.
Now comes to relocking bootloader, you must give more info(what phone you are using) and from where you got the link and what commands you pressed. you can follow this link which uses dec update or (if you check last messages even the feb update though i would recommend dec)
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
and then use the commands given in the code OR the
Code:
OEM Lock file
