Auto root i9506 locked bootloader - Galaxy S 4 Q&A, Help & Troubleshooting

Hey guys, I have had limited experience with rooting. I have been looking for a way to root my i9506 without flashing it. I came across chain fires auto root. The only problem with this is that it says it can brick devices that are have a locked bootloader . I've tried to do some research on that but have yet to find a way that tells me if my i9506 is locked. Is anyone able to provide some extra info on how I check it?

It's not locked. Just go ahead and flash it.

OK thanks for the info, but how do you tell?

The only way to tell would be when you attempted to replace the bootloader, as the device would throw up a warning about tampering. However, unless you live in the United States and have a device from AT&T or Verizon, you have nothing to worry about. It's only the United States that has to worry about locked bootloaders and anti-competitive practices from the carriers who lock them.

Can I change my bootloader on my S4?

Hello all. I just got a new Galaxy S4 (i337m) and I hate the stock firmware on it. I want to install something custom, however the custom roms require a certain bootloader that I do not have. I have searched for if / how I can change my bootloader but none of the forum posts I have found seem to be related to my specific phone so I'm posting this to find out about my specific phone. I believe it is a locked Fido phone. I used the ADB shell to check the bootloader version and it is not the UCUAMDB or UCUAMDL bootloader I need to have for the roms Im interested in. Mine was something like CUVL. I can verify later when I get home. However, can I change my bootloader? If so, are there any instructions for this specific phone? My goal for this phone is a light weight / vanilla version of 5.1.1 Lollipop, rooted. Thanks.
If it's an actual i337m the bootloader is already unlocked... I'm a bit rusty though. I've moved on to a G4, and dumped most of my S4 knowledge with it.

How can I tell if it is unlocked? If it is unlocked, does that mean I can install a different bootloader?

Need help w/ Samsung G900V Galaxy S5 *bootloader/rooting*

I've been a HTC phone person for a while and thinking of switching to a S5 my only problem is I hear the bootloader is locked on VZW Phones?
Now see I'm buying a NEW unlocked G900V Samsung S5 off ebay and gonna trim my sim from my current phone to fit in it, but before I do this I want to unlock the bootloader and then root.
I dont have the phone yet, but its sold as brand new, and I dont have the model, cid, android version, any sort of info until I have the device in my hands.
I watched a few videos saying its easy to unlock the bootloader and root and most people are using touch philz bootloader, and I've read a lot on there saying there is not bootloader access on this device and only a safestrap recovery option
someone said to use geohots towelroot but then someone said he works for google now and its not supported anymore after june 2014 or some ****?
also I seen this video showing me a pretty quick method to unlock the bootloader/root
https://www.youtube.com/watch?v=zKrFxuA5apg
but noticed the video and site was posted before june so Idk if that method still works or not?
any one in this thread know whats the best method to go for and what to do on what works and what I can do with this device or not?
EDIT: found this saying the bootload has been unlocked http://www.xda-developers.com/verizon-galaxy-s5-bootloader-has-been-unlocked/ but still cant find any info on how to do this been searching for 2 hours but also on 2 hours of sleep so idk any help would be obliged
You'll need to find out the CID of the device
Ask the seller to check for you.
If it starts with 11 then you cannot unlock the bootloader. If it starts with 15 then you can unlock it.
Ok I'll try and ask but how do you even find out the CID of the device in case they ask, because I am pretty tech savvy and I don't even know. Samsung phones and CID numbers are all new to me.
I think I read someone where that the CID number changes if u use root on a post somewhere am I wrong ?
anyways if its not a 15 the phones pretty much worthless?
Bump: I asked the sellers to look for me and they always tell me they can not download any apps to the phone...Where do we find this in the settings without downloading anything how can I tell if it's a genuine Samsung chip quickly and easy or not
AFAIK I think the only way is to use an app like EMMC Brickbug or to pull it via adb. There isn't a way to tell otherwise.

I'm just confused please someone help me

I have Samsung Galaxy s4
Model is i9500
But when I go to download mode, I see modem number to sch-i545, which is from Verizon. I want to root my phone and also want to download stock rom or flash custom rom but I don't know which rom to download because I'm confused of which model is correct. My phone has 4G LTE and CDMA. I know i9500 does not support 4G LTE but the model number is i9500 and baseband I9500UBUHOE1. Hope someone cam help me out. Thank you
The correct model # can be found in download mode; therefore, your phone is a Verizon phone with a locked bootloader.

How can I unlock?
Can't be unlocked as far as I know.
Here's a thread about unlocking: http://forum.xda-developers.com/showthread.php?t=2500826
I want to root and install custom rom, you have thread for that?
You may be able to root but no custom Roms based on cm or aosp.
More information about your device is at http://forum.xda-developers.com/galaxy-s4-verizon . In short, unless your device has an early bootloader that would allow modification, there is no way to unlock the bootloader, no way to install a custom ROM, and no way to even root the device.
Return this device and get something else.
could this phone have a locked bootloader AND still have other firmware trying to disguise it at the same time ?
No. It's likely his bootloader is unlocked, but he needs to head to the Verizon S4 forums to be sure. But when it comes to frankenphones, my instant response is to return the phone if possible. Frankenphones are a PITA to deal with.

Samsung Galaxy J3 SM-J320VPP Root help

Hi, and thanks for reading. i would like to know if theres a way of rooting the celphone Samsung Galaxy J3 SM-J320VPP. ive see Threads on sucefully rooting others models but not this one
I agree any dev out there want to let me know what you might possibly need in order to begin to exploit the boot loader. I know that the Samsung n4 fix is for a different chipset but there has to be a way to bypass Verizon's DMV so I can dump the boot loader and system and upload it for the community. I really really like this phone for its price point and I don't feel like that it should be let to the side because it's not a flagship. I'm not a dev but I'm also not new to the capabilities of this community. Any Assistance would be great
My issue is somewhat different, I have a banking app that reports my J3 as rooted (no other apps do) and I need a way to reverse or work around this flaw. The banking app does state for Galaxy S5 model that Android 6 Marshmallow is needed and I know I'm only on 5.1.1, but I'm not sure if the kernel and baseband used are the same.
Any help or advice appreciated. Or if I can root, update to 6 and then unroot to resolve this.
Any news? Just bought this phone on Verizon
No rooting so far. Kingo- and Kingroot APKs and PC versions fail to root, no custom recovery to flash SuperSU, and no vulnerabilities to exploit. I've had this phone for about 5 months now, and nothing sticks. But that's the way it goes with Verizon- branded devices - because the boot loader is locked there isn't much that can be done. The most I've been able to do is "convert" it to a SM-J320V by flashing that firmware via Odin. Still can't use non-Verizon SIMs though.

Does converting it allow you to use Verizon MVNO Sims without paying the ransom for a month of verizon prepaid service first to activate the phone ? I know you said no non Verizon sims but nkt sure if you meant MVNO too

Unlock Bootloader?

Is it even remotely possible to unlock the bootloader? I would love to install a custom recovery and a custom ROM.
Thanks.
Not possible currently, probably never will.
Until someone at Samsung decides to give the keys to the bootloader, it will remain locked.
(Pssst, hey Samsung Developer, there is a fame and fortune for your leak. :angel: )
I vouch 400$ for unlocked bootloader and emotion/lineage os
If S6 is anything to judge by, the chances for an unlocked bootloader are slim at best.
The only reason I would love an unlocked bootloader is to be able to root the stock OS and not have to use an engineering kernel. Otherwise, I tend to run rooted stock on my devices until they get too out of date.
Unfortunately, that means when this S7 Edge becomes obsolete, that will be the end of the line.
No one is even attempting it. With most phones now root / unlocked bootloader is a thing of the past. If you want those feature it'd be best to get a Pixel or a 1+. The rest of the phone will kill all of that in the next year.
The last good for rooting phone from Samsung was the Note 4 and even that was only the Tmobile variant. As Samsung and Android pay roll out internationally it will get killed off over seas too.
Unless a new crop of Android hackers pop-up to replace all the devs who used to roit/unlock the phones rooting and flashing is dying

I'm not sure I would go that far. Sure, Samsung has locked their phones down like nuts, but there are still plenty of developments on other devices. The Sunshine team has managed to S-off every HTC flagship from the M8 on, along with a reasonably sold list of Moto devices. If you aren't on Verizon/AT&T you can skip the hack by going to HTCDev. Too bad HTC has gone absolutely bonkers on their own devices...
The LG V20 folks got "lucky" with Dirty Santa (though I wouldn't touch that mess with a 10 foot pole since your warranty is going to be void at the same time LG is getting sued over boot looping phones). Still, if you manage to get lucky, you can load custom ROMs on that device, and it's a true flagship.
Other devices seem to either have unlockable (through a web-site) bootloaders or have proven relatively easy to mod/root.
One day root may be a thing of the past unless you can find a dev phone, but I don't think we are quite there yet. That, and there will always likely be leaked dev kernels.
Few things:
-Is there any work still being done to get the bootloader unlocked? This dev thread no longer seems to be only devs, rather a bunch of "+1s", "thanks", and "tweet posts". All great posts, but not dev related.
- All devs on this thread are without a doubt better than I regarding android roms, unlocking, etc, but thought id throw a few ideas it here. (Im new to this type of dev). Maybe i can provide new hope? I just recently got the s7 and found out the hard way the current status woth no way to get custom roms. I know the chain of trust, verity, etc are a major buzzkill, but parts have all been hacked before so we can't Judy throw in the towel, can we?!
- http://newandroidbook.com this has a lot of good material, this guy is a genius, too bag he isn't working on this! (Download the book there & supplements).
Couple of actual ideas:
-He mentions in the book, with root you should be able to modify parts of partitions. Add long as you don't modify the entire partition it wont check for integrity on startup. Now that root exists, is Amy of this possible, to modify three partitions and unlock the bootloader?
- He also talks about how the chain of trust works using signed keys, and where to find these keys in the actual image file; since we know exactly where the keys are, and what's expected, can't we fake it with a custom image using a binary editor? He (in that link) also refers to his free tools to inspect, etc.
Remember when wet push via odin the phone isn't online so had no way to verify via internet if something is in fact legit. Hacks happen all the time with fake digital signatures and keys, certs, etc.
- In other words, now that root exists in the engineering kernel, Im thinking new doors have opened.
Thoughts? Hope?!
It's not happening.

I have to agree with Kcodya. With the S8 coming out very soon, I am sure the Devs are not really that concerned with the S7 and unlocking the bootloader. I have read a lot of posts about the very issue and anyone and everyone that has been working on this has dropped it or no longer working on it. Look at the S6. It is still without an unlocked bootloader.
I agree with you about the EngImg and I guess at the present time, that is about all we have to work with. I have settled with it and am happy at least to have root privileges.
But we can still hope...
If Samsung ever gets off their hindquarters and updates the unlocked version of the S7/S7 Edge to Nougat, rooted stock will probably be optimal anyway. I know this is XDA, and people love to mod with whole ROMs, but OEM ROMs have improved dramatically over the years. This isn't the era of requiring CM (or LineageOS now) just to have a functional device like it was during the Gingerbread era.
Unfortunately, Samsung isn't likely to ever sell developer friendly phones again, so if you are a developer or like beta testing ROMs, this isn't your device. There are too many options that are trivial to unlock and develop on for anyone to spend too much effort bucking Samsung on their lockdown strategy.

It's strange that this device never got a stable root. The type of root I was looking for 7 months ago is never going to exist. Development on the root of this phone was forgotten when the S8 came out. I wish I could say the opposite, but unfortunately we couldn't develop a proper root fast enough for the inevitable growth of interest in the newest device.

It's not just that, Samsung also offers some fairly nice bonuses for not rooting and root just isn't what it used to be. The days of "this phone is completely unusable without root to fix all the broken crap" are gone.
I found that simply switching to the unlocked firmware solved 90% of the things I wanted root for in the first place, and probably another 8% were solved by judicious use of ADB and NetGuard. What little was left just wasn't enticing enough to put up with the irritations and work-arounds required for the eng-boot root. I already run Nova launcher exclusively, but even at that, the stock launcher isn't total crap anymore. On the plus side, the eng-boot root doesn't trip Knox, so you can always go back if you want.
Yeah, it's going to suck when updates for the S7 stop due to age, and it would be nice if Samsung would offer a bootloader unlock when that happens, but I suspect it will live the rest of its life with nothing more than the engineering root method.

I entirely agree with you. I haven't rooted my S7 since I tried the engineer boot, and it has been completely and totally usable. I also agree with you about installing the unlocked firmware as it removes most of the bloat that comes with the stock firmware. Root is nice, but not entirely necessary on this device.

So, where might one obtain an unlocked firmware for a G930A? I've searched high and low and have found several different f/w but they all seem to be for other versions of the G930, not the A. Tried to flash mine with one of those and got caught in an endless boot cycle, so had to go back to stock - still locked - and AT&T says the IMEI doesn't belong to them even though it plays their little tune and shows their logo and flashes their name on startup. Pretty useless to me without being able to unlock it. Thoughts or ideas?
Many thanks in advance.

All US/Snapdragon S7s and S7 Edges are hardware identical. You can run any of the 5 variants on them with zero issue (even going between V/S and A/T). This means you can run the unbranded/unlocked firmware on any US/Snapdragon based device as long as the model number matches.
Now, SIM locks are a separate issue. You still have to go to the carrier that locked it (or one of the paid services) to get the unlock code even if you are running the U firmware because the modem firmware is entirely separate.

The firmware for all G930 and G935 variants are interchangeable. When I refer to the unlocked firmware, I'm referring to G930U and G935U. This version can be found on the AT&T Samsung Galaxy S7 and S7 Edge forums on this site. When you install the unlocked firmware, you are not unlocking the device, just the firmware associated with the unlocked version of the phone. This means less bloatware, faster speeds, and no AT&T boot logo. Sorry for the confusion my previous comment may have caused!
