Topic says it. Is there a way to unlock the bootloader and root the original 4.4.2?
I just need the commands from the fastboot panel. This roottoolkit in the development section want to download a whole new nakasi image and I think that this cannot be exept it wants to install crapware on it.
To unlock: fastboot oem unlock
To root: http://forum.xda-developers.com/showthread.php?t=2025272

With very considerable care!
Hi, Daniel120201...
The method I use is via fastboot... I don't know if the various toolkits that are available can flash a bootloader, as I've never used them.
So, using fastboot, the command line syntax is...
Code:
fastboot flash bootloader bootloader-grouper-4.23.img
...for flashing bootloader-grouper-4.23.img on a WiFi only 'grouper' Nexus 7.
The bootloader for the WiFi+3G Nexus 7 ('tilapia') will have a different bootloader name.
** (Edit & addendum: just checked, and as expected, it's called bootloader-tilapia-4.23.img) **
So for a WiFi & 3G Nexus 7, the bootloader flash command would be...
Code:
fastboot flash bootloader bootloader-tilapia-4.23.img
-----------------------------------------
IT'S VITALLY IMPORTANT YOU FLASH THE CORRECT BOOTLOADER FOR YOUR SPECIFIC NEXUS 7. Fastboot flashing an incorrect bootloader to the bootloader partition WILL HARDBRICK the device.
And on that note... and before you do anything... it's important you read the following first...
[WARNING][URGENT] N7 grouper (2012 WiFi) bootloader .img files from Google.
Hope this helps... and good luck.
Rgrds,
Ged.
Ty but I upgraded it before seeing this
You still deserve a thanks

You download the factory image, extract it and it should be one of the files. The just fastboot flash bootloader bootloadername.img

Is it already unlocked? If it is I'm pretty sure it will stay unlocked. But if it isn't, yes you can unlock and root it. Just keep in mind that unlocking the bootloader will wipe your data

It is already unlocked , thanks for the support , you are number 1.
Firstly if this is already mentioned somewhere I apologize and moderator please delete this thread. I was on 5.0.2 lollipop and had my boot loader unlocked with root and I just got back my stock recovery and I'm also on the official marshmallow through ASUS but I'm wanting to know if I'm still unlocked and how if possible I can re-root my phone? Thanks in advance
@corybucher
Bootloader should be unlocked.
To confirm it you can run this command:
Code:
fastboot oem device-info
Output should be 'device unlocked: true'. If not then you know how to unlock it.

Is there anyway to check this from the phone itself?

I think no. Fastboot is only option.
I'm holding off twrp + bootloader unlock because I want to be able to undo in case I need to use my warranty. Is twrp/bootloader unlock reversible? Many thanks
Yes. Flash complete stock everything, boot into bootloader, connect to PC, and "fastboot oem lock".
Is it sure that it works??I have a A2017G and i have open BL and a B29 Custom Rom and i want back to Lock Bootloader

Yup! I've done it plenty of times. You do need to format the data partition though. This could mean that it'll wipe out even your internal storage, so back that up as well!
Im on stock and then i go to edl and then i type fastboot oem lock but nothing happend

Boot into bootloader, not EDL.

and you can unlock it again afterwards?
Never heard of anyone wanting to lock the bootloader so I'd a newb in this kind of thing.

Locking it again is good for when you want to sell the device or send it in for warranty repair.

Yeah, the unlock procedure is the same as before. If you didn't restore the original boot image before the relock, then it's just a matter of booting into fastboot and unlocking the device. Note that this will cause your data to be wiped as well!
If you restore your boot.bin backup file from when your device was locked, does this lock the bootloader? "fastboot oem lock", "fastboot flashing lock" nor "fastboot oem device-info" does nothing for me. Is there any other way to check if your bootloader has been relocked?
Thanks

Hi there,
Were you ever able to re-lock your bootloader on your A2017G?
I just want root for now but understand that I'll need to unlock the bootloader first. Before doing that, I want to make sure I can re-lock the bootloader if needed.
Thanks for letting us know!

Guys/Gals, it is seriously as simple as using the fastboot command in reverse. I've done it a few times already with mine.
If you used the following to unlock....
fastboot devices
fastboot oem unlock
.....then you can use the following commands to relock
fastboot devices
fastboot oem lock
fastboot devices is not necessary, but I do it to make sure the devices is being recognized by ADB/FASTBOOT

Thanks for the answer.
But there are a few files to flash before using that command according to this thread.
Doesn't anything need to be flashed again (e. g. stock files or anything)?
Correct, but you would have already flashed those in order to use the unlock command in the first place.
Are you trying to relock on marshmallow or nougat?

My phone is only a few days old. I'm debating whether to keep it or not (considering the Mate 9, but the price is not the same - love the form factor and bigger screen though - sound won't be the same and I think I'll miss the MiPop button on the Axon (never thought that would happen )).
I'm on the latest MM (B10 - the A2017G model).
Following the mentioned thread, I got to the point of installing TWRP (the signed version), only to realize that besides making backups, there is not much else I can do with that without unlocking the bootloader. I really just wanted to flash supersu and install adaway fro the time being until development matured for this phone (maybe also play around with viper - had great results on my LG G4).
HI, I get the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock". Any way to fix this?
Guys, can anyone help me? I really need to lock the bootloader!
How can I fix the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock"?
I'm on MM B11 Stock.

Hi Guys,
The Axon 7 Model A2017U I just purchased has the bootloader locked and it is running LineageOS 14.1 - 2018032-Nightly-axon7. I need to relock the bootloader and get back to the stock MiFavor rom so that I can send the phone to ZTE for repair. Can you please explain to a newb in some detail how to achieve that.
Thank you.
I'm trying to get one of my E4's ready to sell (I have two of them) and need to relock the bootloader so that the N/A message goes away. I reinstalled the stock firmware provided here using fastboot (and followed the appropriate oem locking steps) but at the very end I get:
Code:
Still require signed boot.img
I am assuming nobody has found a workaround for this as Lenovo hasn't provided official stock firmware and I haven't seen any posts about a solution? Would appreciate any insight.
Not possible currently, just let the buyer know that the bootloader is unlocked and it's root ready lol.
Is it still currently not possible to relock the bootloader?

fastboot oem lock_bootloader
Then go to Motorola.com grab a stock image
Fastboot flash boot boot.img and everything else too.
Fastboot flash
bootloader
oem
Boot
Logo
system
Etc....
I did this and had to use my code that they emailed me to unlock the boot loader again.
I am trying to relock the bootloader in adb terminal by using command fastboot oem lock I get a message during boot stating that the system has been destroyed and boot loop.

use reflash tutorial from this site:
HTML:
https://xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/
. Just download tool, extract, then exctract downloaded rom in this tool folder. Conect A1 in fastboot and start flash_all_lock.bat file in folder with room (I used flash_all.bat). This is how I fixed my bootlops...
You need to reflash. There's no other way.
Did you have the original stock Oreo with January security patch?
I would also like to re-lock the bootloader but now I have read your post I am unsure if its safe.

If I enter fastboot oem relock with MagiskManager or Magisk 15.3 installed, will I brick the phone?

Maybe
I didn't try it but it may brick your phone
Developers should make clear that Re-locking the bootloader is not as easy as the unlock process and there is a high risk you will brick your phone.
