I'm looking to install custom recovery on my Verizon s4 SCH-1545 4.3 VRUEMK2
what would be the best way to go about it thank you so much for any advice
difficulty is not a factor
thanks again
Can't. Locked bootloader with no exploits. Sorry.
My phone i think is unlocked does that make a difference and thanks again for your help

"unlocked" has nothing to do with bootloader being locked down. Plenty of info in this forum concerning locked bootloaders and the options available to us who don't have a MDK base which had an exploit
Unless you have the MDK bootloader, sadly you are not unlocked.
MDK is the only unlockable bootloader, and if you have no idea what I am talking about, you are NOT unlocked and you should do some reading before attempting anything. Hashcode is currently working on a version of Safestrap that is compatible with MJ7 and up, but it is in alpha/very early beta and does not boot anything at the moment.

There's no such thing as an "unlocked" bootloader for this phone. There's an exploit in MDK that lets users bypass the bootloader. That exploit was closed with the ME7 update.

By definition, when you use said exploit, you unlock your bootloader for modification. Please don't uselessly correct people especially when they aren't incorrect in the first place.

Not really. Unlocking a bootloader is different than a bootloader with a Loki exploit.

Entering a house through the window doesn't unlock the door, but it does give you free rein to do so.

That's a very good way to put it lol although you could unlock the door once you're in the house, not exactly the same here. Using Loki is no different to us end users, but a fully unlocked bootloader would make things easier for people like the TWRP team or AdamOutler.

Meh, done arguing. Basically what I'm saying is you can have a custom recovery with the exploit.

Greetings,
I have searched the forums for my answers as well as the web. I am getting a replacement razr from verizon. The rep told me if the phone was rooted or had an unlocked bootloader I would be charged $299. I know if I overlooked anything and this question has been answered I will catch hell .It must be said that I know nothing about rooting and this was my first venture. I used EternityProject EasyRootICS to root. My question is simple did that method of rooting unlock the bootloader on my razr. I wil use superusersu to unroot. Will I have issues with verizon.
Thank you for patience on my ignorance

There is no way to unlock the bootloader so if you are rooted, you can simply fastboot the stock rom and you will be unrooted... The rep is an idiot and wants to scare you because if he knows what he is saying he will never tell you anything about unlocked bootloader on the razr as its impossible....

Thanks for the fast reply. I do not know how to "fastboot the stock rom". Will doing a "full unroot" with superusersu be sufficient. Thank you
If you are stock other than root, i.e. you haven't flashed a leaked OTA or ROM, simply removing root will be sufficient. I would suggest also doing a factory reset.

That is incorrect. The bootloader can be unlocked on the RAZR, but it will only unlock one of the dual core processors. Your "impossible" statement is invalid.

Perhaps you need to do some reading. There is currently no bootloader that is unlockable on the RAZR whether it be the xt909, xt910 or the verizon xt912 version. Some people do have RAZR's that are engineering samples with the efuse in engineering position allowing them full access. There is however a bypass (kexec by kholk) that allows users to load a custom kernel over top of the factory kernel. Currently the custom kernel can only activate one core however a newer version could possibly be in the works that supports ICS/JB and will allow the second core to be operational. This is not unlocking the bootloader but merely loading a custom kernel by the kexec command available in the kernel.
Regarding what the cs rep said, just do an unroot/factory wipe or better yet flash the fastboot for your respective version. There are several guides in the development section on how to do so using RSDLite.

On ICS there is no way to unlock or bypass our bootloader. Kexec is only available to GSM users on Gingerbread, it's not a bootloader unlock tool, it a bootloader bypass. Yes, it is practically impossible to unlock our bootloaders unless Motorola gives an unlock OTA or tool. The reason for this is that there is triple band RSA encryption on it, it would take an insane amount of time for even the most powerful computer that could be sold on the market today to unlock it.

You also need to do some reading, Kexec is just a bypass for custom kernels not radios which is what you can get when it's unlocked. There are also many other things you have to rotk around when using Kexec.

I've seen a few developers posting in this forum saying once root comes (and more users changing roms because of this) they'll port their rom to this phone.
Can we get a list of the devs that pledge to port their rom to this phone?

I think getting people to pledge anything rom wise is a bit extreme
Also, this probably belongs in general or q & a as its not development
If the bootloader is locked can we even install custom roms? I am rooted on dev edition but did not know how to unlock bootloader.

Don't be shocked if you end up with a locked device.
If you care about an unlocked bootloader, you may want to pass on it.

It means Verizon made a patch so you can't use the unlock bootloader method from the last software version.
I wonder if this was to patch that exploit for the exynos processor reported a few weeks back. The side effect of course is a relocked bootloader. That's why I didn't understand why everyone was bringing so much attention to it. Let's pray that Adam can unlock this new bootloader.
The OTA is a side effect of a relocked bootloader, not the fix itself. The original exploit didn't use the Exynos exploit, so I doubt it matters, UNLESS the new bootloader in the OTA has closed the original unlock method.
The exploit needed to be patched. Wayyy too easy for malware to exploit it and screw you.

What if we use insurance to replace our phones and we get one with this locked bootloader? Or what about people buying new phones? My wife's iPhone 4 was actually more valuable with iOS 5 than iOS 6. The iSheep still do not have a jailbreak for iOS 6.

Thanks for this information. I already learned the hard way on my Transformer Infinity to never update before unlocking. This will give me a reason to unlock my Note 2, root it, and install CleanROM, which is also what I have on my Infinity.

Reverting back to stock is so easy....all you need to do is odin flashing stock tar file....which will relock and unroot your phone with working OTA update. And I was referred to current rooted rom users. I don't think they need to be re-unlocked nor re-rooted. Flashing another updated rom and kernel will pretty much take care of everything. Besides, adrenalyne already has bootloader safe OTA update working......so there is no point of worrying. However, if someone is planning to buy a new phone and needs his or her phone updated, then yes.

Fixes the exynos exploit, locks the bootloader, and updates the radio. Possibly some other minor patches looking at the patch file sizes.
Stay away from the ota unless you use the safe one I created in another thread. Ignore AdamOutler's comment in this thread as it turned out to be wrong and people got locked up in the process.

Depends on the kernel. I couldn't tell you with third party kernels, but the latest stock one from the ota closes the exploit and is safe to flash.

I don't understand. Are you having a problem unlocking your bootloader. Or just don't want to, but want to flash your custom rom. without the bootloader being unlocked you will have to flash certing things like the kernel manually everytime you flash a rom.

Actually I've already unlocked and rooted using Outler/Radeklav's method, but I'd like to know for other people who have asked if it's possible to root, keep stock ROM and keep the bootloader unlocked for above vrajb phones. (I know you can do it for vrajb phones using the Exynos exploit.)

The only way to root only on VRAMC3 is with the Toolkit, there are mixed results with it though. Some say it works great and some say it doesn't work at all, in the end the people that just want root can try that and if it doesn't work they should just root and unlock the bootloader with CASUAL and if they don't want to mess with flashing they don't have to. There are really no downsides to having an unlocked boot loader aside from not being able to accept and install OTAs, that's a plus in my book though.

I am currently running a Verizon Samsung Galaxy S4 SCH-i545 NC5. I've been wanting CyanogenMod for a while now, but from what it seems the bootloader is completely locked for the S4. I have read that it is possible to downgrade to an older version to get the unlocked bootloader, is this possible? If it is possible I don't know which version to downgrade to... ME7, MDK, MJ7?
Thanks
not possible. if you're running MDK you can do the loki exploit but anything other than MDK is not able to be patched, worked around, etc.

Follow the video if you want. If you manager to downgrade to MDK you can TOTALLY use the loki exploit to work around the locked bootloader and use a custom recover.
However, you can't downgrade a Verizon S4 to MDK. If you manage to get the software on your phone, it wont boot (or your really smart). There is a 148 page thread at the very top of this forum called "If we are serious about unlocking the bootloader". You think that would still be going if you could just downgrade?

Dont think it would even work. It verifies something (Think it was the MD5 or something?) in the file and if its a lower version it will just block you from proceeding.

There's a bootloader value number and firmware won't flash if it has a lower number. Firmwares such as nc5 and nc2, as well as mk2 and mj7, can be downgraded because they have the same bootloader value.
