Generally, you can't flash a custom rom with a locked bootloader, although there are some exceptions for certain roms on certain devices. However, I am not aware of any such roms for the M4.
No you can't.

I am so confused, and let me be the first to apologize for my stupidity. Many years ago I had a Droid, and life was so easy, you rooted, you added a ROM and Kernel, and life was good. Today, I have the Galaxy S4 and I am rooted, and I thought this was going to be as easy as it was back then, but I got to read about the nightmares people were having, so I stayed rooted and didn't go any further, for I was afraid I was going to brick my new phone. Now, I am reading that you can't go further because of the bootloader is locked, so how are people loading ROM's with it locked? So, as a person such as myself who has not a clue about all this techy stuff, can you load a ROM with a locked bootloader? I am asking if someone can simplify all this for me. Thanks.

Did your phone take the ME7 update or come with ME7 on it ? If so, root, debloat, Titanium Backup, play with Nova Launcher for customization is about as far as you can go at present. If you are lucky enough to have an MDK build then you can root, install custom recovery, flash roms & kernels to your heart's content. To find which you have : If you are stock, go to settings, more, about phone. Scroll down. If you see VRUAME7, in baseband, build and have not installed any custom roms then you are out of luck. If you see VRUAMDK, Congratulations! You are golden.

Verizon has locked down the bootloader for ME7 based roms...I personally would not alter the state of your phone until a bootloader unlock has been achieved. Please see Hascode's OP at http://forum.xda-developers.com/sho...E7] Safestrap Recovery v3.5x [WIP DISCUSSION]

This why I joined this forum, for everyone is so knowledgeable and willing to help. I thank you all for you replies, and yes, I am on ME7, and I guess I have to sit it out until there is hope. Thank you.
Hey i got a quick question for everyone,
Do you think the CyanogenMod installer will work with the rooted but locked bootloader of the GS4
Answer yes or no and a reason behind your answer
I don't think it would work, I haven't tired it myself but I would think the Cyangenmod Installer would still have to change the bootloader, unless it has some built in work-around. I would suggest just installing a recovery instead of using the installer, also CWM or TWRP allow you to make backups of your stock rom. You would still have to unlock the boot loader though.

No. It's for Nexus devices first off and you can not flash a ROM on a locked bootloader without an exploit.

Just picking peoples brains i have a GS4 on MJ7 Rooted and a Galaxy Nexus with TWRP running CM 11 4.4.2 nightly im just dying here waiting for the GS4 to be unlocked but it doesnt look like anytime soon
What provider are you using?? My vzw s4 had the Unlocked Icon on it when it first turned on, I think it was just a workaround but I had a custom recovery and rom on it.

I do too, i am also on VZW but that is not the bootloader that is just saying you have Root Permissions
Have you tried to install a custom recovery yet, I think once your rooted, you can install the recovery.
Yes I have I used Goo Manager to try to install TWRP and it will brick your device but only soft brick so you can use Kies to do emergency firmware restore and it will start right back up.
Oh yeah your right, my bad. I originally rooted my S4 in June so it wasn't the MJ7.
im just waiting paciently for a bootloader unlock and since im not part of the progress i cant complain like most people where i was part of the jailbreaking community im now just getting into android.
Not sure if you saw this thread, but it seems to be updated frequently. Looks like it may be a least an alternative to the stock rom.

Hey guys,
First of i'm not sure if this is a appropriate thread to ask this, if not i'm sorry and will move/remove it.
Anyways it's been awhile since i've been in the android scene and xda in general, had an iphone for about a year or two and just recently got my Z2:victory: so i'm back but things changed a little and i need a little info if anyone can help,
Basically i'm looking to flash [Xperia Z2] DooMKernel v09 kernel but i read it requires an unlocked bootloader... so basically i need to know if my bootloaders unlocked now that i flashed recovery (check signature) (Does flashing recovery unlock a bootloader?) and can i just flash the zip?
or do i need to still unlock my bootloader even though i have dual recovery and then flash the kernel?
Your bootloader is still locked, what you did is you installed recovery for locked bootloader.
Do not try to flash custom kernel on locked bootloader, you'll soft brick your phone.
What you need in order to flash custom kernel is to unlock bootloader, but firstly you need to back up your TA keys ( click here )
For more info click HERE (about unlocking)
Proceed carefully!
Regards!
hey thanks for the info, that' clears up everything, I did already backup my TA partition so I guess all I need to do is unlock bootloader then flash the kernel! quick question have you flashed your kernel? I know I read the info an features of it but is there any upside to it on a z2? my device is pretty fast an stable as is, just looking for a reason to flash mine, any further advice you can give me? is it worth it?

Well to be honest, I haven't, I didn't find any reason to do so, the stock is doing good for me at the moment.
As for the side affects, or as you say upside downs, there is no any, not at least that I'm aware of, but as far as I saw it's not compatible with every rom, only with stock as with stock based ones, I mean developer does not guarantee for it's stability if it's being used along with any other rom. I have rooted and flashed recoveries only to use existenz rom. I heard for Doomlord's kernel, that it has "fix" for a video recorder mic, you can control it's sensitivity and it's far more battery friendly.
Ah I see! thanks, think I'll stick with the stock kernel for the time being, I don't have any complaints at the moment with it but if I ever do decide to switch to the doom kernel atleast I know what to do first, I've got one last question though sorry, do I need to unlock my bootloader to flash a custom rom? I don't think I do, I'm pretty sure I don't, but just want to make sure, used to have only low end droid devices back in the day when I used to be here, didn't have things like dual recoveries etc so yeah I'm kind of reading an learning as I'm going along, pretty awesome device though sleek and powerful I've only been doing minor adjustments to the stock rom using xposed modules, haven't used a custom rom as yet but I will soon...

Well, yes and no, LB means its for locked bootloaders and UB means for unlocked bootloaders, search for those to two words when you find the rom which you can flash.
Some roms require unlocking, some do not. All stock based roms usually dont require, but as I told you, it will be stated in Rom's thread name or in OP.
Regards!
Ah! I'll be sure to look out for those, thanks for the valuable info, think that's all I needed to find out. I should be ok from here on out
Hey. After spending hours trying to discover a working method to root my Verizon Samsung Galaxy S4, I've succeeded. Now, I want to try to install some sort of bootloader like TWRP or something so I can install a custom ROM. What do I install and HOW do I install a bootloader? I'm confused. I also want to install the the latest CyanogenMod for it. I think I can do that on my own after getting a bootloader installed on my phone, but what file am I supposed to be installing is the question. Thank you for any and all help. This is my first smartphone, so I'm trying to figure this out.

Right now the bootloader is still locked down for the Verizon (unless your phone is on the MDK bootloader). So unfortunately you won't be able to do more than root the phone. You can use Safestrap to use some ROMs, but I don't think CM exists for the Verizon S4.

Oh, that's a shame. I was looking forward to this part. I wondered why I only found outdated information or a lack of information. I don't even know what a good ROM would be for this phone if there's no Cyanogen for it. Well I appreciate your reply very much. Thank you.

There is a Cyanogen build for the Verizon GS4 but as mentioned, only for folks with the MDK bootloader. Only TouchWiz based roms can be used with SafeStrap - no AOSP based roms (yet).
To see what bootlader you are on, just go to ABOUT PHONE under settings.
Hi!
I have a Kindle Fire HDX 7 (Thor).
Some time ago I installed safestrap and flashed a CM 11 ROM in stock slot.
Now I want to update this ROM, but I can't find new ROMs with safestrap support.
Can I unlock bootloader, install TWRP and flash LineageOS?
Can I use this 1click tool? https://forum.xda-developers.com/kindle-fire-hdx/general/multi-platform-1-click-bootloader-t3241014
Safestrap version: 4.01 (TWRP 2.7.0.1)
ROM, not the last update. https://forum.xda-developers.com/ki...-cm-11-safestrap-20150628-unofficial-t3145547

Hey man, I'm in the same exact boat but can't get any of those steps to work, could you explain better what was done as I really need to get off from CM11 and move to something better and supported.

Happy to provide more detailed guidance (several have taken a similar leap) but will be traveling the next few days with limited XDA access. You can find everything you need in the HDX forum (several threads dedicated to the topic) or just hang tight until I return.

Sorry but now I can't remember precisely what I did.
None of the steps works? I remember that the first step (generate the unlock code) was flawless.
If even the first step doesn't work maybe you have adb drivers problem, so check the prerequisites section here https://forum.xda-developers.com/ki...r-firmware-t3463982/post70881555#post70881555
