Okay, I messed up big time Im rooted {TOWELROOT} on 4.4.2, And i Flashed TWRP, without unlocking a bootloader, My phone said that it could not boot and gave me that please visit a store for help, I found out i need a unlocked bootloader, Somehow i booted my phone (In Android), But My locked bootloader is still out There, Please help!
YES this is a American S3 SCH-I535
Now its hard brick

You need to report your post and get it moved to the verizon s3 forum. This is the i9300 international version. Anything you flash from here will brick your phone plus the i9300 does not have a locked bootloader.

NEED HELP on How NOT to lock the Bootloader on a MDK s4

I need some help here, We (the wife and me) bought two s4's New a year ago and both was MDK, I Rooted and loaded a custom Rom, All was good until a few months ago when I wanted to put a Newer Rom on my phone, I started flashing this Rom and that Rom and then I had this problem! I had loaded a Rom or ????? that Locked my Bootloader and Now I'm unable to Flash Rom's
I'm really a Noob at this I only root my own phones and Need help here So I don't do it again to my wifes phone which Needs to be updated, it's on 4.2.2 MDK She has a New s5 and I'm taking her phone.
(1) Please tell me what I need to know to NOT Lock the Bootloader ???
(2) What is the Newest Debloated Stock vzw Rom Need Wifi Hotspot ??
(3) Steps for Flashing, I want to be sure I'm doing it right......
Thank You for your Help in Advance
Are you sure her s5 is mdk bootloader? The mdk bootloader was on the first released s4.
Essentially once you have a custom rom and and u locked bootloader, never take a verizon ota update. That usually patches known exploits to your phones bootloader and locks it down. What was the last rom you flashed that locked your bootloader?
Also, did you have a custom recovery installed? Can you get back to your custom recovery? If so, you're bootloader is not locked. You will have to wipe your phone clean and flash a new rom.
I will be working on her older phone, the s4 with the MDK bootloader and Now has become mine, Her new phone is the s5 and it's happily Rooted with S-S and a custom Rom.

[Q] Want to unlock bootloader on s3 i9300 running 4.3, please help?

New to the whole rooting process, want to flash custom roms but don't know how to unlock bootloader (if it isn't already unlocked, I've read that most samsungs have it pre-unlocked but have also read that it is locked on 4.3 and is problematic when trying to unlock)
Search first, there are hundreds of identical questions.
The i9300 doesn't have a locked bootloader, unless it is a Chinese firmware.

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...

can installing stock rom in an unlocked phone lock it again

..I was already told by a friend in xda group that if I again flash a stock rom in my sm-900p phone which I got unlocked for international GSM use (using from India) , it won't get locked again ...with all due respect to the friend who affirmed me already that it won't get locked ,can anyone else confirm that to me please ? I am not able to dare to flash the stock rom....since two days I am just waiting to take that step..presently I am using darkwolf rom but I want to flash with stock rom so that bootloader and modem gets updated and then on that version,I will flash this rom again ..that's my plan
It will not relock for international use. If it does for some reason, you can use Galaxy Tools to unlock again, assuming you root. But if it was originally unlocked either officially with Sprint or via root + Galaxy Tools, then it won't relock. If you were in the US, you would have to change some other settings to re-enable domestic unlock but international sticks.

Hi,
I assume you are talking about the Samsung Galaxy S2 i9100 international variant.
The bootloader doesn't need to be unlocked, you can root and flash custom recovery and ROM making sure you are running the latest official samsung firmware (4.1.2. jellybean).

The Samsung Galaxy S2 GT i9100 is the exact model. But hey, thanks for your help. Does this phone intentionally come with the bootloader unlocked or something?
