SCH-i545 (I545VRSGPL1) Bootloader unlock or downgrade? - Verizon Samsung Galaxy S 4

I own a Verizon Galaxy S4, and it has the PL1 firmware, I spent entire days searching to unlock the bootloader or downgrade to the android 4.4.2 firmware. I can't afford another phone for quite a while, and VoLTE is not supported, always in 3G. does anyone here has or know any way/ways to unlock the bootloader? I mean, the device was released in 2013, I quite sure there would be some methods to unlock the bootloader, right? Anyone? Please help?

Found anything yet?

[Q] How to unlock P769 with no T-Mobile service

I bought a P769 to use internationally and have no T-mobile plan (I use Sprint in the USA). I want to get CM 10.1 on it. What are my options? From what I understand, I need to get the OTA Jellybean update in order to unlock in order to flash CM10.1.
Thanks.

There are plenty of tutorials available. Read a bit.
You will need to have T-Mobile unlock the device for non-T-Mobile sim cards.

You don't need OTA Jelltbean to unlock bootloader and flash CM10.1, but you need a unlock code to unlock the network/SIM lock to use other SIM than T-Mobile. You can buy the unlock code from eBay.
I don't believe P769 can work on Sprint.

I already unlocked the phone's SIM for international use. That's not my question. (eBay solution was used). Of course not to be used on Sprint.
Can someone at least point me to which tutorial to follow? I'll tell you what I tried [GUIDE][JB] Unlock Bootloader and FASTER Root L9 Method http://forum.xda-developers.com/showthread.php?t=2221102. When I did the adb reboot oem-unlock command, the phone just restarted. I assumed this was because I have Ice Cream Sandwich which does not have the oem-unlock command.
I am sorry if I am asking a stupid question. I assumed the guides on here required the JB update which does have an unlocked bootloader apparently.
Is this the one to use? http://forum.xda-developers.com/showthread.php?t=2198114. This one suggests that we should wait for JB update. Is there any way to manually install the JB update instead of going through what seems to be a difficult procedure?

As kevev said, read a bit. Maybe a bit more.
Regarding qingz's answer to your Sprint information it is easily assumed that you were trying to use Sprint since you mentioned it. There are a lot of questions by a lot of people in a wide range of expertise. Always think of how what you ask will be perceived/interpreted by others to get the best answer for yourself.
Keep a humble attitude of learning and you'll go far, if not people won't answer our questions if we come off brash and know-it-all-ish.
To root, I just did using cmahendra's offline flashing method. It is easily on the first page of the L9 forum. It is a beast to accomplish, but go for it. Please note, when you get to step 11 you cannot "sit back with your hands folded behind your head" as it says, you have to go *back* to the original instructions and copy/paste a file. I share this because that part was not clear, and cost me about 5 or 6 hours of time with re-doing the steps over and over again.
Good luck!

Make sure you follow to a tee, read original bl unlock thread and make sure your wifi is on and connected to internet. Wait at least 1 hour before issuing command.

Bootloader Unlock info for S6 Edge? Only with Unlocked bootloader we can root?

Can we get a thread to consolidate information about the locked bootloader?
I need root, and waiting for an exploit to root might take a long time (or never), so the only other option is to get the phone unlocked?
Is the manufacturer able to unlock the bootloader? Is there a way to splice a root into a factory update?
SIM unlock and bootloader unlock are totally separate, so none of the 'unlock' services frequently advertised will be able to unlock the bootloader?
I'm am seriously frustrated by not having boot access, to the point that I am considering selling the phone and getting an HTC or Sony.
What really sucks is I bought this phone off-contract directly from Samsung because I thought only Carriers phones had bootloader locks.
FYI my version is the SM-G9250 (Asia spec phone).
That sucks.
I recommend you return or sell it and buy a T Mobile S6 or S6 Edge. After 14 days of purchase, they will unlock the phone. Also, it comes with unlocked bootloader and root is now available.
How do you check if bootloader is locked or not? I have an international version (F).
Thanks

Perfect.. Thanks
Liking this phone more and more...
Unfortunately I spend most of my time in Asia, so I don't have much of a choice. This phone has more coverage...and there is no cooling off/return period in Taiwan. I can only sell it as a used phone.
So the T-Mobile us version comes with an unlocked bootloader? This is the deciding factor of me purchasing this device .

This is amazing. I never knew T-Mobile did this. What's the protocol for unlocking after the first 14 days?
I think its 40 days, or something similar
just call them and ask them, they will tell you exactly how you do it
I'm from other country holding the G925I version

I'm So EXCITED! Samsung provides factory bootloader unlocking!
I posted the details here:

Is the boot loader in the Hong Kong version locked too?
Hiya, does anyone know if the Canadian version (SM-G925W8) comes with a locked bootloader? I'm trying to root the device but it just keeps failing in odin.
According to this, the latest update for T Mobile locks the boot loader guys. http://forum.xda-developers.com/showthread.php?t=3096169

Can I install CyanogenMod?

Just recently purchased the Xperia Z2 Tablet and I'm very disappointed to find that I can't unlock my bootloader. I read a post on here that mentioned it was still possible to install CM on a locked bootloader. Could anyone explain to me how I could do this or link me to a thread that will help? Here's my device info:
Model SPG561
Android v4.4.4
Build 23.0.1E.0.208
Currently unrooted.
I actually got this today after returning a tablet just because I couldn't install CM or unlock the bootloader. I'm very close to just returning this and getting a different one. If I'm **** out of luck with the Z2, could anyone recommend a Verizon LTE tablet, with good specs, that will allow me to unlock the bootloader? I'm getting desperate.
Thanks for any help.

I can't see how you could flash CM on a locked boot loader as it requires a custom kernel.
I don't know anything about the Samsung tablets on vzw but I suspect they are locked down. The LG tablet can be "unlocked" with bump but its a piece of garbage. If the Nexus 9 is available for vzw its probably your only chance at getting an unlocked boot loader. Some of kindle fire tablets can be unlocked as well but they need to be on older firmware AFAIK
Unlocl boot loader
Yes you can unlock bootloader by going the sony site and follow the instructions. I ask you for the emei number ad other things. but follow the instructions carefully.
2nd option. Use Sony mobile flasher by androxyde it works perfectly well on mine. But if youneed to update or upgrade through Sony Compagnon, you will need to relock bootloader, install update and the (re) unlock bootloader. It works for me...

Any news on the VS990 Verizon Variant?

Haven't seen any info on the Verizon version. Is there anyone working on unlocking the bootloader and getting root? Is there anything I can provide off my phone to help it along?
Bootloader is locked. Have to get an OS root method/exploit.
the situation is dire. we have begun operation brick wall.
It's going to get even worst when MM comes out and will likely need a custom kernel
This is messed up

Procedures for unlocking bootloader?

I have a Verizon S4 Mini that I have been dying to try to get this bootloader unlocked. I know there isn't one available, but I am wondering if there is any documentation on any of the Samsung bootloader unlocks. I'd love to dive into bootloader unlocking but don't know enough, so does anyone know of any documentation?
