[Q] How to unlock boot loader and flash a stock android ROM? - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

I don't like touchwiz and I need help on how to flash a Rom that would function like Google's Android versions found on nexus devices. Can someone help me out? I already used towelroot to gain root access.

If you would read or use search function you would know we cannot unlock the bootloader. We have safestrap recovery which can only flash TW based roms

The bootloader is still locked and most likely will not be able to be unlocked. You can flash other ROMS if you are rooted using "Safe Strap" found here. http://forum.xda-developers.com/showthread.php?t=2793891 . There are no Android stock roms out for the S5 yet so not much you can do yet.

Any safestrap compatible for 4.4.2 roms now that official Kit Kat is out?

I've searched but haven't found anything other than jelly bean safestrap roms. is it safe to assume that at some point any safestrap compatible 4.4.2 roms might become available now that the M has a official kit kat?
Not sure what for as long as there's no root for locked phones.
No I meant any safestrap compatible 4.4.2 ROMS available now that official kitkat is out. Sorry should have been more clear.
I have a rooted but bootloader locked 4.1 razr m running Safestrap. As far as I know there have not been many options for ROMs being safestrap compatible for anything above 4.2
This would require KitKat with a 3.0 kernel, but KitKat on 3.0 just isn't KitKat.

The issue with KitKat is it's a different kernel. In order to reap the benefits of KitKat, you need to run the latest kernel.

Therefore, don't expect to see a SS KitKat ROM.

4.2 ROMs barely worked, I wouldn't even want to see a 4.4. Also, what version of 4.1 are you running? If you're still on one of the older versions, you might be able to to unlock the bootloader and get rid of SS.

Yes, it never hurts to try and see if the bootloader will unlock. Some people had to run the utility twice to get it to work. We had one individual on this forum that refused to listen to the benefits, until we badgered him enough (well, more like encouraged him) to really see the flaws in his logic. He wanted to keep root and be able to use TiBu to restore his apps, but then he stated he didn't care about root. But, I explained to him that going to KK will cause him to lose root and the ability to use TiBu, so he would have no way of restoring his apps and their related data since that required root.
We then explained that attempting to unlock the bootloader will NOT harm his phone. He tried it and after the second try, he had an unlocked phone. Now, he doesn't have to wait for an exploit (if it ever comes) to root KitKat. He can just sideload it now via ADB.
So, try to unlock it. Worse that can happen is, you'll find that an OTA was applied that fixed the exploit, or you could get lucky like the person I was just talking about and have an unlocked bootloader which will allow you to obtain root with KitKat.

Looking for Canadian i337m users.

Hello all. First off I have a I337m with baseband NE1. I never see this mentioned anywhere and wanted to know what I can do with this phone.
I've rooted already (with towelroot) and wanted to get a custom bootloader. I've read and read then read somemore but found too many mixed staments regarding this.
Can I install a custom bootloader (say through goo manager) without worries or is there more to it? Does it completely overwrite the stock bootloader?
Do I need to worry about Loki?
Can we use other carrier ROMs?
Is it safe to say that everything in this sub forum works with my device?
Im familiar with flashing and the likes coming from the S2 with CM10.2 but there are too many varients and mixed statments (old to new methods) and I can't for the life of me find direction.
This is what I know about the i337m, mind you I don't have the device:
You can root using chainfires cf-auto root
Use trwp manager to install twrp
You can flash any rom here and you don't need Loki

I have the same phone on Telus... as far as the "custom bootloader" I think you really mean custom recovery, I use TWRP version 2.7. You can also use Philz recovery or CWM but I perfer TWRP as it hasnt given me any issues. If you load TWRP don't go for the latest version as I have seen guys have problems with the latest and greatest.
Once you have twrp on your phone... before you do anything else... make a backup in twrp of your current rooted stock rom so you have a starting point. In twrp, I like to do all backups to the external sd card as there may come a time where you do a factory wipe... and poof its gone...
In the developement thread... there is a rom called Mapleleaf works very well on this phone... I run it myself with the googy-max3 kernel.
If you decide to flash anything else... make sure it will work for i337m, I have seen people get into trouble flashing things meant for the US version (i337). Our bootloader is unlocked so you don't need saftey strap or loki or other things that the i337 users need.
When in doubt... search the forum... if you find nothing... ask before you do anything strange.
As far as the bootloader goes... try to stay on your current one.. mine is still MK6. Once the bootloader is updated there is no going back... period.....
This helped a lot man, I appreciate it.
So just to clarify, can I use goo manager for the recovery or should I use Odin? And is there any version in particular [TWRP] that I should use? What version are you running?
How do I check my bootloader version?

You can use goo manager or Odin. Just make sure you have the right version. FYI twrp 2.5.0.2 is the most reliable version that I have used for this device.
Tapatalked from California Custom Chrome M&M I337m
If you want an older version of twrp use odin... goomanager will likely try to load the latest version... as for checking which bootloader version you have, download the app phone info from the play store.... here... https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en
my version of twrp is 2.6.3.1 and it works fine... as stated... 2.5 is also recommended by some of the devs....
My bootloader ends in NE1, does that pose a problem - I rarely see it mentioned anywhere? I took the OTA in case anyone is wondering. Basically, can I flash something that's not NE1?
Also, I've been reading that the ROM that's going to be flashed needs to be the same Android Version as the current one on the phone, is this still true?

This will mean you can flash any rom (for i337m) that is 4.4.2 version of android. You can always go up on android version to bootloader but you can't go down versions unless the bootloader is an earlier version. Since most roms are 4.4.2 or higher, I don't think this should be an issue, not many people are looking to go to an older version of android..... bigger... better and all that...

Is this true, bc I have a bell galaxy 4, 4.4.2 i337m NE1 , I want to install a custom recovery,
but I thought my bootloader was locked because its says write protection enabled on the download screen which I thought
meant the bootloader was locked.

The I337M bootloader is not locked. What you are seeing when you boot after rooting is that you tripped KNOX since new bootloaders are closely tied to KNOX so any violation = tripped KNOX.
I have I337M from Telus with NE1 bootloader (4.4.2) and custom Rom PhoeniX. Everything is great except a newly discovered TD Bank App and inability to link my TD Visa to it...

Very doubtful someone will guide you step by step, the general idea is to root your phone, install a custom recovery, then install a ROM, there are many guides on how to do this which are tried and tested.
Have a search, it's hard to miss them.

Downgrade your device if you're on a new firmware, use a firmware for your model, flash it via odin (there are plenty of tutorials) root using towel root and you have a rooted phone, the way I did it will void your warranty and knox will be set to 0x1, this happens when you flash something you shouldn't via odin, I flashed a custom recovery, bootloader and modem via odin so my counter is no longer 0x0, there is a way you can root, install a custom recovery and flash a rom, find the Neat Rom thread in android development, get everything you need from there and fire away.
Research and read everything, until you understand it, but the general idea is, root, recovery then rom, forget about original android development for now, concentrate on actually finding a rom that will work on your device, the most common is mine which is the 900f, you're on h so you need to find one that is compatible, don't leap in without guiding yourself first, check and double check.
Good luck.

As most custom roms are pre-rooted flashing a recovery with Odin will do and there is no need to root the device first , then make a nandroid backup of your current rom in recovery and flash the rom (and Gapps for CM) of your choice. Flashing a custom recovery/kernel may void warranty though as KNOX will be tripped to 0x1. As you have the G900H CM is not option atm. You could root the phone and freeze all not needed apps and widgets with Titanium Backup.

Root with I337UCUGOK2 bootloader

I can't seem to find a straight answer to my question since most of the info for the S4 is 2 or 3 years old now.
So I have a completely stock ATT i337 running Android 5.0.1 with the I337UCUGOK2 bootloader. My soft keys aren't working, so I would like to install a different ROM to try to fix. I understand I need to install CWM or TWRP first. So my question is this... Is my bootloader locked and I need to root my phone first before I can install either recovery? If so, what method do I need to follow for my version of Android?
I understand that with time there are improvements. Some stuff I've read makes it sound like there is a lot of automation in installing custom recoveries, and maybe I don't need to root first because they root for me.
Thanks.

Sprint Galaxy S4 Rooting

I've spent hours searching and I know this is an old phone. Is ther anyway to root the Lollipop and download Jelly Bean (custom or stock) to it? I'm not worried about Warranties. I'm not exactly a newb and I don't like Lollipop at all. I don't mind KitKat, but what I hate is the front facing camera can't be flipped. Dumbest thing ever.

I'm supposedly rooted. I used KingRoot and then switched over yo SuperSU. But I can't seem to get the Rom's to install. This is where I'm probably going wrong. I'm assuming it has to do with the Bootloader.

Ask the right questions if you want the right answer.
You said you're not a newb. So what exactly was the procedure used to to install those ROMs?
Well, you should be using CF-Autoroot, as it's the recommended method to root these devices. That said, unless you have a frankenphone, only AT&T and Verizon models have locked bootloaders. Enter download mode and verify your device's model number please?

I was half asleep and stressed out when I posted this. It's been a couple weeks or longer since I messed with the phone. Damn forums weren't resetting my password. When I mean I'm not a newb I mean I'm not like brand new to this and I know how to research. I guess you could say I'm not THAT stupid. haha
I'mma have to try this again and figure out what path's I kept trying. I'm so spaced out I can't remember hard any of it. Just that I tried to flash a stock and rooted rom with old odin and new odin. Spent 2 days straight messing with it and trying to get around it. But I kept getting blocked. I didn't come across CF-Autoroot. So I'll try that.

Of all the researching I've done (I couldn't login) that one never showed up in my searchs. haha I'll have to give that one a try. It's been a couple weeks or longer. SPH-L720. I had a few Tri-Bands, but it seemed those were limited compared to the standard model.
Update: I went the CF-AutoRoot route and then tried to use Odin to flash stock mk2 rom. Now that I remember it kept failing everytime and then it would corrupt the current rom. I also tried using TWRP and couldn't get it to work properly.
That's a Sprint device, so your bootloader is unlocked.
Here's something you should note: If you want to flash a ROM, of any kind, you don't necessarily have to be rooted.
Stock ROMs require Odin and custom ROMs require a custom recovery. None of them require root.
Your flash to an older version fails most probably due to the fact that you're trying to downgrade the bootloader (Any stock ROM flash also modifies the bootloader and modem partitions).
But your windows, cable, USB port and windows can also be at fault here.

For some reason I kept reading that it was locked or thinking it was locked because of not being able to downgrade.
So that's what I thought and I guess that's what I was trying to get at in my first post. Trying to go from Lollipop 5 to Jelly Bean 4.3 or so. Is it possible to do that whether it's custom or not?
I just hate the Lollipop and the KitKat. My Galaxy S2 had the JB and Power Button took a crap. So I ended up getting a S3 and now been sitting on an S4.
I know it's not the cable or at least it shouldn't be because it works to flash the stock current rom everytime I corrupt it. The computer is like brand new and running Windows 8.1

Downgrading sometimes succeeds. There are also guides on how to downgrade, though there aren't any special procedures. Maybe the bootloader version of the firmware-to-be-flashed matters.
With custom ROMs it's definitely possible, as they do not change the bootloader.

I guess I'm more of a newb with this than I expected. :/ It's been years since I've been on the forums or even tinkered with phones. HTC Touch Pro 2 was the last one I believe. haha
So... With that being said. Custom Roms are typically to the current stock rom, correct? or is it possible to get a Custom Jelly Bean and flash/overwrite it to the Lollipop/current? Since I just tripped wit the Knox Warranty with the CF-AutoRoot. LoL

If you can find some viable download links, then yes, you should be able to flash custom jelly bean ROMs. But you need a custom recovery in order to do that.
The recovery can be flashed with Odin. Or, since you're rooted, you can also flash a recovery by using an app called Flashify.
Odin requires a .tar file and Flashify requires a .img file.
Oh, and you also need the gapps package for the Google Apps. You need a package for that specific android version, so it should be jelly bean gapps.
