O4X Unlock relock bootloader tool - LG Optimus 4X HD

All Thanks to @Derjan23
I used Code from his post here
thanks to @OopsWare for his analysis of this code here
Disclaimer:
I am not responsible for any damage at your device!
You're running this program on your own risk!
Here's unlock Program it does the following
1-try to read odm_reserved
2-check if your bootloader unlocked or locked
3-calculate the most effective string that you have to echo to reverse bootloader state(it will relock if your Bootloader is unlocked - unlock if your Bootloader is locked
4-you can copy echo command and use it after su root in terminal
DONT BLOWN ALL FUSES WITH echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved
by using this program you have 16 chances to unlock relock bootloader before all fuses blown
you can read how this works here

Someone tested on 262?

the official method checks this numbers before unlock and this method unlock directly so sure it works - if you don't already know 262 234 232 even sim locked is unlocked with odm hack I only modified it to do whats really needed only - so you have other chances to relock unlock

Yes....
I love you...
lol...
This worked perfectly....
The only thing that worked for me....
Thank you.

For me its showing "Permanently Locked All Fuses Are Blown" but only unlocked one time (manual method)
But I send it to service maybe they did something to permanently lock bootloader?!?

There's several of them, just search and read mate.

this method works if you used official bootloader unlock method or used my program to unlock - if you used the other hack method echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved then you have no more chances to relock - anyone can't relock should check /sys/firmware/fuse/odm_reserved contents with es file explorer before and after using program
this program for LG 4X only and you should have stock JB and rooted device

[Q] How to check if the bootloader is unlocked.

Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.
Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.
Sent from my C6603 using xda premium
but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc
use flashtool to tell you
Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.
How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

I unlocked my Xperia Z and in Service Mode I can see 'Bootloader unlocked: Yes'.
Now my phone is running on latest C6603 firmware and DooM Kernel.
To my surprise, BE2 still works! Music info download still works! TrackID still works!:victory:
But not picture enhancement in album right? Hope you backed up TA partition before unlocking
Sent from my C6603 using xda app-developers app
im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!
just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

Fastboot issues,bootloader (un)locked?

So I've unlocked the bootloader on my xperia Z the official way. Entered the unlock key and it was successful.
However, if I try to write a recovery in fastboot I get the error : Remote: not allowed.
I have made sure I have the correct drivers and all but it still doesn't work. Even tried unlocking it again with a second unlock key.
How can I fix this?

not only allowed or not
if you have locked bootloader it says it is allowed
if you have unlocked bootloader it says that your bootloader is unlocked
you can check your bootloader by this way , cause your error determines that u have lockbootloader

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

u welcome!
just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL
TA Partition backup

you will loose guarantee either way as the bootloader will show as tempered. More chance to keep it valid if you use the tools HTC provided.
Orange should work just fine. Just try...
On another note i sent 2 phones for repair to HTC "unlocked" and they never charge me for the repair.
yes, i was thinking of only gettin root and not unlocking bootloader

You can undo the root and unlocked bootloader, before you send it to HTC. If you cannot undo because you have too big problems with the phone (frozzen phone,...) they cannot controll it either.

Can I relock my bootloader?

Hey, so my Moto G got an unlocked bootloader, but I'm selling it to get the Moto G 2015 (or any phone good as it). Is there a way to relock the bootloader, so I can handle it to the new owner good as stock?
In terminal type 'fastboot oem lock'. It's relocked then, not locked, that means the warranty is still gone but the functionality is the same as from a locked bootloader.

Unlocking bootloader: definitive bye-bye to automatic updates?

With the Moto Z, after I returned the phone to stock (flashed stock firmware and locked the bootloader), I'd be able to flash stock firmware with the flashing locked.
Not so with the Motorola One Zoom. In other words, flashing stock and re-locking didn't return the phone to its pristine state. Even when flashing stock firmware over stock firmware, I have to unlock the bootloader.
Differences I observed: on the bootloader screen, when re-locked the Z would show "oem_locked" again. On the One Zoom, it shows "flashing_locked" instead. I'm pretty sure it showed "oem_locked" before unlocking.
WIth the Z, every time I wanted to unlock the bootloader, I had to issue "fastboot oem unlock" followed by the unlock code. The code isn't necessary with the re-locked One Zoom.
In other words, maybe it was a one-way trip. It seems that the phone won't return to its original state, it looks it's modified for good. And I'm afraid this means bye-bye to automatic updates.
Am I missing something here?

What region is your device manufactured for?
Does your PC see your device connected to the fastboot mod?
What does this command give you:

Also, It's Rooted with Magisk and have Riru EdXposed installed, can I install my OTA updates without bootloop or do I have to Uninstall Magisk, relock bootloader and factory reset/flash stock firmware to get latest OTA updates?
Any feedback is appreciated.
