maybe reboot oem-lock will do it
did that to my nexus 10 and it relock the bootloader
never tried it on my l9

Congrats for flashing: At the moment it seems Unlocking Bootloader is ONE-WAY-TICKET. You cannot LOCK it BACK. Phone connection will affect once you flash JB. dont worry.

thanks gdjindal. was going to paste it.
I have answered that in one more place with following info.
Unlocking Bootloader is ONE-WAY-TICKET, at least at the moment. You cannot LOCK it BACK. In most countries, unlocking voids warranty and you are shown this warning before you unlock.
There could be some countries and some specific phone models where unlocking does not voids warranty.

If you can get hold of a pre jelly bean dump for your phone you can flash partition 1 and 2 as x-loader and u_boot and your bootloader is relocked

can you tell me please, how can i get a dump ? i am noob at this.

http://forum.xda-developers.com/showthread.php?t=2173613
I used this guy's dump and I'm not 100% how to obtain it myself. If you pm the OP he can tell you how he did it. Then if someone with your phone is kind enough to provide you with their dumps, you can go from there.
Why do you need to re lock your bootloader though? Maybe we can help you find a different solution to whatever problem you're experiencing.

I don't think flashing ub and xl will relock bootloader.
btw to dump xloader i uboot to sdcard on rooted phone
adb shell su -c busybox dd if=/dev/block/mmcblk0p2 of=/sdcard/external_sd/u-boot.img
adb shell su -c busybox dd if=/dev/block/mmcblk0p1 of=/sdcard/external_sd/x-loader.img
update: also i think since unlocking requires active sim and probably data that whole process is logged by lg

Yea I'm not sure. I was talking to pinoyto in PM's last night while he was working on unlocking p769 bootloader. I gave him the u-boot and x-loader I had and he said it was locked again after flashing those. Like you said though if its logged by LG it probably doesn't matter if you're able to relock it or not.

Is there anyone who successfully relocked it? Or all these are still at experimental level?

After flashing uboot and x-loader you get a security error. Does that indicate a locked bootloader? I think it does, but I'm still very new and just learning and experimenting.

So if you have JB on it OR after flashing JB, then you should get Unlock Menu with "adb reboot oem-unlock" asking for unlock choice.
If yes, this is good news.

Hello cmahendra,
After reading last few conversations it sounds like now we can relock bootloader. If yes then please guide us...

The unlocking procedure definitely unlocks something permanently. If you flash the old x-loader and u-boot, you will get a security error but if you try to unlock the bootloader again, you just go straight to fastboot without the option to unlock it.

to relock the bootloader just type this in when you are in the bootloader screen where it says fastboot usb
Code:
fastboot oem lock
then you can run the RUU then after the RUU is done flash you Unlock_code.bin and it will re-unlock the bootloader then you can take the OTA
please delete

I would also like to know the answer to your question.
Install. A stock rooted odexed rom. delete superuser.apk from /system
install stock recovery found in the international forums ( do this in fastboot)
issue the command fastboot oem lock in fastboot
the bootloader will say relocked, and I think it will still say tampered, but I'm not sure

No. Unlock_code.bin is specific to the phone you get it for.

HTC Quick Root

Can anyone confirm if the HTC Quick Root tool is working for both rooting and fully unrooting?
I need to able to unroot as easily as possible should something happen to my device, since I've only had it for a few days and is still on warranty, which is why I'm avoiding unlocking the bootloader for now.
Attached is the software information screenshot, if necessary.

As far as I know, any (un)rooting tool will unlock your bootloader to get the job done. Quick Root (along with similar tools, like hasoon2000's "All In One toolkit") will merely automate the process, making it easier. The end result is the same, though: An unlock code will have been requested from HTC, and some fusebits will have been blown. Your warranty may or may not be void.
So essentially, there is no way to root without unlocking the bootloader?

I know I'm derailing the thread a bit here, but assuming I do unlock the bootloader and lock it again afterwards for warranty purposes, is there any way to change the RELOCKED warning to LOCKED?
Apparently the following does just that for other HTC devices which have a signed hboot - can anyone confirm?
Code:
fastboot oem writesecureflag 3

You can't change RELOCKED. After first unlock of bootloader you lose warranty for ever.

In the first link, the instructions are to run a RUU (which as far as I understand will set the device to S-ON) and then to run "fastboot oem writesecureflag 3", so I don't quite understand why S-OFF is required.

How can i lock the bootloader again?

Sorry they are a dumb questions , i don't know.
I unlocked bootloader and installed cwn , and rooted my rom.
I have two questions:
1. Can i have root and cwn with locked bootloader? (guess not .. but not sure)
2. Can i lock again bootloader? say if I flash stock ics via lg tool or..
please don't laugh or something.. i'm new here and curious. (after i rooted my phone and tried a few roms i end up to the conclusion that it's better with bootloader locked and root only)

You don't have to install the 20B again, all you need is it's u-boot.img. If you don't have the u-boot.img, just extract it from the kdz. Open this thread in a browser, and look at my signature.
