[Q] How to re-lock Galaxy S4 ME7 bootloader - Verizon Samsung Galaxy S 4

It's a tough thing to search for. Google thinks I'm looking to root or unlock my phone.
I've followed the steps in a video thread entitled "[HOW TO] Unbrick, Unroot, Relock Verizon Galaxy S4" successfully. However the padlock icon is unlocked when the device boots up.
Can Odin or similar tool re-lock the bootloader of an ME7 Galaxy S4?
Do I need to PDA back to MDK?
Not concerned with losing files. Just need to return the device to factory stock.

Well first of all you might be a little confused here... the ME7 firmware currently has no way to unlock the bootloader yet so if you somehow found a way please share with us and collect your money
Anyway, you can get back to stock using this guide: http://forum.xda-developers.com/showthread.php?t=2301259

I have a locked brand new s4 if you wanna trade lol

Boot into recovery and clear the cache.
My phone is rooted with xposed framework with Wanam Xposed and I don't have the screen that indicates "custom" and my device shows up as official in the about screen.
I also have taken the recent OTA.

That worked, Craw.
Thank you & goodnight.

[Q] Verizon Note II root/unlock bootloader Q

Hi I have been away from the scene awhile now and in the process of rooting and unlocking my Note 2's boot-loader. Am I right to assume that all I need to do is use casual on Linux Mint 14 "Nadia" - Cinnamon (64-bit) and it will both root and unlock the boot-loader of my phone. I ask this because I have read this stickie:
HTML:
http://forum.xda-developers.com/showthread.php?t=2024207
and it says to first root with odin and then use casual to unlock the boot-loader. Just ant to make sure casual both roots and unlocks without me needing t use odin first. Thanks in advanced.

[Q] Unlock bootloader to root?

I thought it was necessary to unlock the bootloader on android phones before i could root them and flash different roms. A buddy of mine had rooted his old s3 but forgot to unlock the bootloader, so when he tried restarting it, it soft bricked. For the longest time I thought you had to unlock the bootloader then root the phone in order to flash custom roms, have I been wrong all this time?
Think of the Loki workaround as a way to trick the bootloader into flashing improperly signed files. Its like using a credit card on the bolt of a locked door. The door is still locked but you get through anyway.

And what are the risks of using the loki tool if you use it correctly? if there is an OTA update to the phone, will it mess it all up?
You don't you the tool...the developers do. And technically, it is only used for flashing a recovery and flashing ROMS with the recovery. You can root without unlocking the bootloader because there is an pre-release official rootable kernel than can be flashed with Odin. It flashes because it is legit.
So I should be able to just go to the how to root page on here http://forum.xda-developers.com/showthread.php?t=2290798 and follow the instructions and flash one of the roms as usual?
yes,go ahead

[Q] BEST Way to take Samsung Galaxy Note II i605 4.3 (UEMJ9) to CUSTOM ROM R3Ds

I have tried Flashing my Note II to the new RD3s Rom and bricked my phone due to the locked bootloader. I was able to restore my phone back to the factory Rom 4.3 UEMJ9, BUT I WOULD LIKE TO TRY THIS AGAIN. How should I go about this? Should I flash my phone back to VRALJB or VRAMC3 to be able to unlock the bootloader or is there a way to do it with the present UEMJ9 Build. Thank you for your help!!!!

I am guessing you used Odin to flash mj9 4.3. Once you have done that or accepted the ota for mj9 or above, there is no going back to a previous version. Your bootloader is locked with currently no way to unlock it.

So is there anyway to try custom roms without unlocking the bootloader? Or should I just upgrade to kit kat and take it on the chin?

root and boot loader unlock?

Im sorry if this has been answered in other threads im simply trying to help a friend out with rooting and possibly unlocking the boot loader? Can someone point me in the rite direction? It would be most appreciated
I would check the Verizon LG G3 forums where there are many instances of your questions having been already thoroughly answered.
What you will find is that you must be on v10b firmware, which you can downgrade to using either the .kdz or the .TOT method, then you can root v10b (only) with StumpRoot, or ioRoot, or PurpleDrake, before the phone updates back to v12b. With SuperSu in survival mode root can be retained through either of the current OTA updates (which provide very little enhancement beyond patching root exploits), so far, and with root you can install a specially modified TWRP recovery which will allow the flashing of unsigned kernels and roms.
There. You are on your own from hete on.

use flashify to install the bumped version of twrp (get it from the original development section). Worked like a charm. Plenty of bumped roms to grab in the dev section.

There is no unlocking of the bootloader. Bumping doesn't unlock the bootloader. However, it fools the phone into allowing the flashing of custom ROMs and kernels without unlocking the bootloader. Basically, the phone "believes" that whatever is being flashed (via TWRP) is acceptable and allows the image to pass the "security check" that is done when flashing. It's the same thing as IF the bootloader were unlocked, but in reality, it isn't unlocked. It's a security exploit, kind of like rooting this phone is a security exploit.
However, a quick OTA patch from Verizon or LG could make either or both no longer work. In fact, some OTAs have fixed the root exploit on some models, so you have to flash back to a previous version to root.
You have to root first, then you can flash TWRP.
As stated, there are plenty of FAQs in the general G3 section that help explain all of this.
OK thanks guys. Um just used to seeing a sticky on root under original android development I have no idea what firm ware he's running ik how restrictive big red can be at&t is no better but that's why when they offered a nexus I went and grabbed it
He's wanting a lollipop rom

Updating from NC5?

I'm looking to update my mom's phone, I honestly don't remember what I did to it in the past. As far as I can tell it's rooted on NC5, with a lock boot loader (I assume although when booting up I see an unlocked lock with the words "custom" underneath it) and knox is 0x0. Does that mean my bootloader is actually unlocked? and am I following this guide (http://forum.xda-developers.com/gal...-to-root-i545vrufnk1-4-4-2-12-1-2014-t2959613) to update to the latest version?
Thanks
You are most likely rooted but for sure your bootloader is still locked. As far as updating, if you don't want to keep root or anything then just odin back to stock and accept an OTA. If you want root then there are other ways to update posted in this forum.
