Is this possible? - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

Hello all! I know that on NK2 and lower there's been the ability to downgrade and upgrade firmware using Odin. However, with the Lollipop update coming soon is it possible that that could be fixed and the bootloader could be updated to fix that? Also, is it possible that (if it is a bootloader update that would fix that) that there would be an exploit left in there for the bootloader to be unlocked, and if there is what are the odds of someone finding the exploit?

With every update has come tighter and harder to crack security. Right now the chances of the bootloader being unlocked are slim to none. With the lollipop update, I would think those chances would fall to below zero and into the negative probability.

With Lollipop any phones that are in proximity to your Samsung device will have their boot loaders locked as well.:laugh:

being able to downgrade firmware isnt asomething they might "fix" since it is not something broken, it was meant to be that way.. now them making L to where it is not downgradeable is very likely since it will be a whole new OS/Firmware than 4.4.x with a slightly new file structure/runtime.
I think its time to realise that the S5 will NOT have an unlocked bootloader and if it does it will not happen until weve most likely moved on to other devices. The only hope for an unlock is if a dev working on the Note 4 or another ddvice find an exploit that also works on our S5 since I havent heard any devs still working on it with our device.
I believe root will be possible on L if you are patient and dont take the OTA and wait for a dev to push a L rom.zip and odin firmware. (Theres no reason I can think of as to why this would not work as it always has)

If you have spend some time in searching the forum, you would have had the answers faster than posting here and waiting for someone to reply.
There is no current direct method root available if you are running Android v2.3.3 and anything beyond .145 firmware.
If you need to flash a rooted firmware, you need to unlock the bootloader. Otherwise you will not be able to flash it. If you still need a rooted firmware, please search the firmware, there are few of them available i guess.
Hope this helps.
And when asked so nicely, i am sure people are rushing to fix it......
I really hope SE would just go that one step further and would just give us a pre-rooted bloatless global .ftf, even if it's unsupported. It'd be nice for us and would increase their reputation on XDA tenfold
I think your chances of winning the lottery are higher than the chances of them releasing a pre-rooted version

I'm not sure, SE is acting pretty awesomely lately, and I even think they might bring is the next Nexus.
If SE makes their Kernel insecure that's good enough
here ya go: http://forum.xda-developers.com/showthread.php?t=1203729
thread starter said to:
1. flash a non-rooted 4.0.A.2.368 rom first (which you can find here: http://forum.xda-developers.com/showthread.php?t=1204302)
2. and then flash the img file he provided.
one thing that the thread starter left vague was proper instructions for the not so techy users so...
that being said, I am therefore unsure if you can flash the img file with a locked bootloader so get someone else to confirm that for everybody
IMG flash only on those phone which have unlock bootloader
but a branded or sim lock phone have locked bootloader and there is no way to unlock them
SE not open it for sim locked phone
thats why i am asking rooted 4.0.A.2.368 global in FTF format

Can't get the S4 for 2 more weeks...

I've read a few posts stating the bootloader exploit for the S4 would be relatively easy to patch by At&t and my concern is that they may do so before my upgrade on June 7. If at&t does patch it before then would it be possible to use Odin to downgrade the phone to an earlier firmware release that doesn't have the patch? If not I'll have to figure out a way to get the phone as soon as possible.

I don't see how anyone could know that for sure at this point. However, if a patch is released (OTA) or if newer firmware is put on the phones that patches the vulnerability itself, then it seems realistic that ODIN probably will not be able to fix the issue. Once it is patched, you probably won't be able to go back. Of course, another exploit might be found or Adam's attempt at a more permanent bottloader unlocker might find a solution. OTA updates can be fixed by just not taking them until they are cleared as OK. Newer firmware on the phone would probably need another fix. But nobody knows how long it will be until AT&T / Samsung patches the vulnerability.

In anticipation for Sony's Lollipop Update

1. Is it advised to gain root NOW prior to the forthcoming Sony Lollipop OTA?
Point being if I don't root and I update to the latest forthcoming lollipop ROM from Sony then will it become a difficulty to gain root via the current downgrade method of rooting.. Or will downgrading from Sony's lollipop ROM be easily achieved via flashing .93 from flastool for instance.
My idea being can I remain unrooted and update via forthcoming ota from Sony and still achieve root via the current root methods of downgrading.
2. If I gain root now though, and lose ota facility because of root then will i be able to flash the latest official Sony lollipop ROM via flashtool manually and still retain root?
Sorry for any repetition above it's crazy late here. I've been itching to root but have been holding off in anticipation of an imminent Sony lollipop release... After some thought on the questions I post above I'm trying to determine if it's best to root now to prevent a potentially unrootable Sony lollipop rom?
Thanks in advance
1. Will downgrade from lollipop be possible? I have seen both happing with other devices so could go either way. No guarantees because we just don't know yet.
2. There is no downside to rooting now. Once you're rooted you don't want to install any official OTA anyway. You could lose root or even damage the device (we don't know yet). What you want to do is flash Pre - rooted firmware which you can download in the forums here (usually you get updates sooner than through OTA this way)
It's like a whole new world once you familiarised yourself with the possibilities.
Root is recommended you don't have any downside. If you want the ota update so bad you can still decide to flash your current software again. Though this I would not recommend since there is a possibility that you will be stuck in lollipop like clouds5 said (if no downgrade possible) .I don't think this will be happening since Sony until now is not really restricting users to flash official firmware. Hell they even encourage bootloader unlock officially. That said, just root and the enjoy the countless advantages.
As another alternative, and only because it hasn't been pointed out, you could also try to simply remain confused. The challenge in this is in hopefully coming to a point of peace with your circumstance by no longer worrying about it. I've been awake for far too long and have been sleep deprived over the past days, thus having no business making posts like this and accepting ir as innapropriate, but the general philosophy expressed remains solid ?
Since i don't have it in my signature, don't forget to hit "Thanks" ?

I will proceed to root now to prevent an unrootable Sony lollipop OTA ROM - which is incredibly likely given chanfires views on the difficulties of rooting lollipop "specifically devices with locked bootlaoders."
Given we would all like to retain our DRM keys for when reverting to stock based ROMs I think I've come to my conclusion.
Thanks for your thoughts, it has certainly helped to proceed with rooting now (with I've been itching to do) rather than wait patiently for Sony's lollipop OTA (which could become a hindrance, now that I've fully understood the 'potential' for an unrootable lollipop ROM.)
I like your signature ;o)

Jeah it is very unlikely that L will get root since it has already been obtained and the bounty is fulfilled. So there is no real motivation to keep working on it for this device. And also like Clouds5 said you will probably get your hands on rooted stock lollipop sooner here than through the official OTA update. Or 1-2 days later. Enjoy it .
Root now or regret it later.
I'd recommend you root now. The ability to get OTA updates is not a big deal at all. If you root, you can still install stock roms which would be just like the OTA roms. Sometimes the unofficial stock roms come out sooner than the OTAs, if not, then very shortly after. I actually like SONY's stock rom. I'm rooted, and I plan to just use the stock rom with some root enabled modifications.
I'd say that most custom roms are just as good or better than official stock roms from OTA.
With my last phone, I regretted not rooting when I had the chance. Sure, I was okay with it overall, but I wished I had root so I could have my phone exactly the way I wanted. There were some really useful functions that I missed from having a rooted phone, like screen-off music player controls. I missed being able to tether without the carrier knowing.
Some companies are making it harder and harder to root, so I say root now while you can.
If you root now, you're in control. If you wait for OTA, who knows.

Root on Nougat

So Nougat has been released for AT&T Users. I realize that Root for Nougat has not been achieved yet, but I want to get the ball rolling and start a discussion on the topic.
I'm assuming the engineering kernel root won't work on nougat, so we are once again without root. Has any development begun on root? I know there is pretty much no chance unlocking the bootloaders, but how long do you think it will be before we can get root? A month? maybe two? Do we know who is working on it?

It's doubtful that anyone is working on root. The engineering kernel was a lucky break for us on MM, but for Nougat we most likely won't see root unless someone unlocks the bootloader. Google has been increasing the security of Android with each update, so exploits are getting harder to find. Even if we do get the su binary in place, dm-verity will stop us from booting, and disabling dm-verity seems to require a kernel modification which the locked bootloader doesn't allow. I'm sure people are interested in unlocking the bootloader of our phone, but considering the history of Samsung devices and bootloaders, that chance doesn't look great. Maybe somebody ought to start searching for a new engineering kernel... it'd be a better leak than some blurry device pictures
Or if you got your hand on the international version, it seem that the international version is still rootable.
I really new to the Samsung dev scene so please forgive any ignorance.
Is this what you're looking for? It seems to claim root on the G930A on Nougat.

Don't use it if your chipset is not Snapdragon.
THIS IS NOT FOR THE EXYNOS VERSION OF THE S7! <- this was the big fat warning for anybody not reading it. My phone is currently the Exynos version, so I won't be able to root it.

[Help Needed] A Fresh Idea to Get Root

Hello XDA community,
This is my first post on here and I hope I'm not doing something wrong in terms of protocol, but I have a rough idea on finding a root for this phone that needs support and refining from you guys, the XDA community.
My idea is this: If we can find a way to downgrade the phone software back to before the December 2016 security patch, we can run a Dirty Cow root exploit (, which is ready to go on GitHub, ) to temp root this device (or any device, in theory). Once we have temp root, we could run a program like SunShine or whatever else to turn that temp root to perm root. (SunShine currently says that, to full root this device, it needs some kind of temp root.)
Now going back to the first part about downgrading the software to before the December 2016 security update, I initially thought we could achieve this through mfastboot or RSD Lite, since they allow flashing of officially signed Motorola firmwares. However, I read that when upgrading the Moto Z, and presumably all other variants, from Android MM to Android N, the (locked) bootloader is updated, too, and will not allow downgrading, resulting in a prevalidaton error. This is where I need your help.
The question is: How can we downgrade the firmware back to MM, or some other before-December firmware, to use Dirty Cow for root. Please leave ANY suggestions in the comments.
Thank you for your time and help. I have faith that we will be able to solve this together.
I don't think you can downgrade. But i've been running this for the past 9 or so months to prevent the forced updates: https://forum.xda-developers.com/moto-z-play/themes/app-moto-z-play-apps-stop-ota-motocare-t3538812
(no idea if that would work on the z force)
Well I know there are many videos on YouTube claiming to downgrade certain Moto devices through RSD Lite or mfastboot for different budget Moto devices, but I suspect they are all fake. Nonetheless, I hope there is a legitimate way to downgrade.
I forgot to mention that if you can get a replacement Moto Z Force from Verizon, which is very easy to do in my area, they ship you a refurbished replacement, which runs marshmallow and has no updates installed, but I don't have the opportunity to get another replacement, so for anyone else, that's one way you could "downgrade" and try Dirty Cow to root the device.
I'm just going by this topic https://forum.xda-developers.com/moto-z/how-to/dont-upgrade-to-nougat-ota-t3524456
but i don't really know for sure
Wow. Now I wish I'd known about this MUCH sooner. Its too late for me. Well, in that case, try to see if you can revert back to marshmallow if you unofficially upgraded to nougat and check what month of security patches you are on. If it's before the December 2016 security patch, then you can run Dirty Cow and get temporary root. With temp root you can most likely find a way to make it permanent root.
