bootloader. - Samsung Galaxy S8+ Questions & Answers

Been seeing development arising for the s8 and + Sammy devices and root has been achieved and mods can be applied. The question that keeps rolling through my head is why is the S8 and the SD 835 such a hard one to crack as far as being unlocked for custom recovery, mods, roms, performance tweaking. I'm just curious to why this unlock is unachievable and where and what stops it from happening. To me having TWRP installed is a huge safety net and I'll be honest I miss having it. Maybe someone can enlighten me to why this is such a pain in the arse to achieve.

I know what you mean man! It used to be the other way around I'm up in Canada and we've never had locked bootloaders until this phone came around. It's crying shame that you can't use any other Rom except for what it comes with.

Right I'm sure eventually it'll get unlocked because you have 4 phones that are identical in hardware and the only difference is what the carrier has put in it. Then you have the international version that can be unlocked and they've got development for that version. I'm sure there's way to many smart cookies on here to not happen. They've achieved root and all the other goodies. It'll happen just takes time.

I doubt it ever will be unlocked. The S7 still hasn't been unlocked despite sharing the same hardware across carriers in the US. Damn efuse and secure boot. The other issue is that we wouldn't really have source to do anything and it would be an uphill struggle to get anything substantial.

What is the likelihood of a 2.2 root?

Hey guys,
I know there are plenty of people working on finding a method for root, it's difficult, not trying to ask when it's going to be or why it's taking so long. I'm just wondering if it will even be possible, given HTC doesn't ever unlock the phone themselves. I love the One X, just got it and I think it's great, but I know that I'm going to eventually want to install MIUI or CM, and since my phone has 2.2 there's basically no way to do that right now.
Reading through some of the dev/think tank threads, I've read a couple of comments alluding to the idea that it might be impossible unless HTC unlocks it, and that they might not. Seems contrary to what I've seen in the past, pretty much every phone I or my friends have had got cracked at some point. Still, if it's not going to be possible ever, I might want to return my phone and switch it out for the SGS3 or some other.
I tried to Google for unrootable android phones and couldn't find any. However the percentage of devices using ics is very small and the only ones that have root as far as I can tell all have unlocked bootloaders.
It's very difficult to remain positive but I'm trying.

Y'all are so impatient!
Like any security, it just takes enough careful effort and determination to defeat. As great as the One X is, I have no doubt there will be enough of both to get this done. :good:

I don't have the technical expertise to really say. But just from experience, I can say that HTC has been desperately trying to lock down their phones for over 2 years (maybe longer, that is justs when I jumped into the Android game) with some pretty sophisticated safeguards, and the phones have still been rooted, often very quickly. I don't think HTC has magically gotten better at securing their devices, to the point that the phone is now impossible to root. In particular, our device was rooted (1.73 firmware) something like 3 days after it was released, even with the locked bootloader and all the security that HTC could throw on it at the time. Its just my feeling that its really doubtful that HTC can go from that point, to making the device impossible to root in the matter of a few months..
Seen this new root method here on xda, any idea if compatible with our 1X?

Apparently not: http://forum.xda-developers.com/showthread.php?p=31435583#post31435583

Is anybody close to unlocking the latest bootloaders, or is it unlikely?

I (very) recently got a Verizon Galaxy S6 and (stupidly) allowed the updates to run :silly:. I should have known better, as I went through the unlocking/rooting process with Verizon's S3. I could live with it for a bit if people think it will be unlocked in the near future (I'm on VRU4BOG9), but if there's a reason that it's unlikely that it will ever be unlocked, I can still return it and cancel my plan. I could just change carriers, but it's a little tricky because it involves my wife's phone/line, as well.
Does anyone have any information or opinions regarding this?
Thanks!
I'm with you in the same boat.
It was past the baseband even before i let the updates run.
I doubt there will be anything. This forum is pretty dead. No developers etc. I am going to look into getting a tmobile s6 and see if I can unlock, root and get it working on verizon. I think it can be done I've just not looked into it yet so not for sure.

t-mo has CDMA radio?
or you plan to run LTE only?
i would be interested to find out as well
It's unlikely.. as some of the recent dev posts have made clear samsung is the ultimate anti-developer company... as such most of the dev's that would normally work on this have moved on to other brands. It's also gotten to the point that it's almost impossible to actually unlock.. they almost always work around it rather than unlock it, and there are only so many of these workarounds out there.
It may get rooted again, but it will be very unlikely that the bootloader gets unlocked.. basically our only hope would be a leaked test bootloader thats already unlocked.. But I've only ever heard of this happening once.
Take it back while you can. Had my s6 rooted on 5.0.2 but there was no xposed support or xposed for it. If you enjoy rooting your phone the outlook is not good. Not much going on with this scene. After owning mine for just 2 months I sold mine on eBay and am headed towards a nexus. Not a bad phone but not good for flashing...I will do my research next time before getting a Samsung !

Becoming less and less happy that I bought this phone. Especially on the payment plan. I may have to bite the bullet, pay it off and just sell it for whatever I can get. Sucks. I loved my fascinate, my S3, and my S4. Been using my Moto Maxx 2 more and more lately. THAT'S SAD.

Besides the Nexus what model phones are now dev friendly? I was looking at a G4 but apparently LG is just like Samsung with the nearly uncrackable locked bootloaders now.
s5 just got full bootloader unlock..
Is it Verizon or the Exynos chip that's holding back development on this device? ELI5
Sent from my XT1565 using Tapatalk
It's the customized software that samsung builds for Verizon that limits access to root and bootloader. Without having root privileges, you can not make any system changes let alone access it. The chip has nothing to do with this.
s5 just got bootloader unlock BUT the dev has not said he will release anything. It may never happen on this device. having said that the debloater is the key to a smooth device with good battery. If debloating is all you need, that can be done without root.
After debloating about 150 apps on my s6, I can get days and days on battery with minimal use.
This who ordeal with Samsung screwing us on the S6 is making me want to switch to a Nexus...

S7 bootloader unlock petition

Anybody interested in the bootloader and unlocking it I encourage you to sign this petition. These phones are ours to use how we see fit and the more noise we make the better our chances are. I bought this phone under the assumption that nothing had changed and for Samsung to change their policies without notice isn't acceptable for me and hopefully you as well. Thank you
Petition
Dude, there's honestly no point. Ive been on xda for about 10 years and ive always need to root every single android phone ive owned. Until recently, Samsung started making pretty good android phones starting with the s6 and up. I had no reason to root my s6, note 5, and now no reason to root my s7 edge. Im not saying you should have no need to root yours, i just feel like Samsung and android have come a long way and nowadays rooting serves no purpose;for me at least. Is rooting worth losing Samsung pay or any other security features we need to protect us? Not really. Also, Samsung can change their policies as they please, you still bought their phone. Rooting died a couple years ago, move on. Best of luck with your petition.
No point is simply just not true. I haven't even looked at a Samsung until the S6 last year and I got the M9 instead. Now with HTC dumping boomsound on the M10 I switched after 8 HTC phones. While I agree Samsung has come a long way not only in hardware but software and you can do more things now without root I still miss it a lot. Have this phone a week now, not having root sucks. It's just not the same. While yes you can do quite a bit without it, there is still plenty missing. People saying that root is dead or they don't need it is just denial for the fact that things have got so locked down it's not worth justifying the hassle which might just be true.
Let's say knox was never developed, triangle away still worked so you could also go back to stock and you could flash away with an unlocked bootloader everyone would be singing a totally different tune and you guys would be rooted. Now that Samsung has total control, we have to justify it to ourselves on why it makes sense not to root which frankly right now I think is the case.

Its all good if you have no interest then that's fine but I for one do. I hate touchjiz and the bloatware that is just the tip of the iceberg. Rooting will never die maybe some people don't but most that have rooted will always want it. Thanks for your input though. Without root we really don't have any need for a development section so this forum will likely die. I'm jumping ship to the lg g5 until samsung does something if they ever do.

I personally have no problem with Samsung locking things down. In fact for the general pop it will be great, but since we live in the free world it Samsung should still allow the option of choice. As long as they have the proper disclaimer in place that warns of consequences the one can make the decision. I think the big reason for the locked bootloader has to do with carriers leasing the phones. Since rooting breaks the pay app and can't reversed. Just imagine if you got a previous leased phone and the pay app doesn't work. What samsung should do is allow for a complete reset factory action including knox. Maybe not have it available to the general public but maybe the carriers or somewhere higher up. This would give the best of both worlds.

Dude you've been here 5 years. I've been here 7. Neither of which matters. Rooting didn't die any more than rock and roll did when disco came along.
I drive a semi and without root I can't get the headphone, or bluetooth, volumes high enough when running through the trucks stereo. And before you start talking about headphones, those that cover both ears are illegal and i don't like listening through only one ear. So I want root. If you don't that's wonderful for you, but please don't step onto a developers board, claim seniority you just don't have, and try to tell people the board has become meaningless.

This is my second account ive definitely been here since the palm and original HTC touch days with Windows pocket lol. But to the point, rooting is dead per se, but there's definitely less of a reason to do so these days. Touch wiz is damn near perfect. Even for those thay dont like it can slap a launcher on it. I see no purpose to root, i can block ads with ad guard. Also stock android doesnt have all the bells and whistles either so id rsther stay stock. Again, i know others may need it, but i was simply saying its pointless thess days. I still come here for many other things, just not to root.

Are not 'needed' and 'pointless' antonyms? You just refuted your own statement.
And I don't use stock android. I use rooted and modded versions of Sprint's base ROM. The only stock versions I have truly liked and used are by Temesek, and those tend to be few and far between on Sprint variants.
I also never use Touchwiz. It's been NovaLauncher for years now for me. And I just prefer all the little conveniences and tweaks that you can make with root. Like an extended power menu without having to add more apps from Google Play. And several diagnostic tools I use to troubleshoot when I have a weak or slow signal where I shouldn't.
So I'm really happy that your content to live with what Samsung and Sprint deign to allow you, I'm not. And since these boards seem to be doing just fine, I would guess that there are enough people who agree with me to make your opinion not nearly as wide spread as you believe it to be.
And one final question, if you believe rooting is pointless and dead, why are you still on these boards?

Root or not to root is a matter of opinion, I think it is far from dead or useless imo.
I have rooted every phone I have ever had that it was capable on within 24 hours of getting the phone just because I want to put on the phone what I want not what Samsung thinks I want.
I don't fit well with the masses and rooting let's me be that way with my phone....
That said this has been seen before on other devices and has been worked around by the amazing devs on this sight.

Rooting will never die unless the manufacturers kill it. It has too much of a following with people that love to root and need to root. So yes no root is a huge deal for me I'm coming from a Nexus 6 where I had multirom and weekly updates. The phone never gets boring when it is unleashed and rootable. I have had the Edge for about a week and I'm already bored/frustrated with it. I'm going to the Sprint store today to try and return it. My Nexus 6 flies compared to the S7 Edge even though its specs are way better. Hardware can only get you so far the software is what makes the phone fly. The stock S7 Edge has so much BS bloatware and unneeded stuff that slows it down significantly. Give me the international one and maybe I would keep it. Also, the Samsung pay is a joke for me because it doesn't support any of my banks or cards. I will be preordering the LG G5 or waiting for the next Nexus.
We should have the option.
I don't really need to root today, because I primarily use the phone for business and I don't want to have it down because I change my mind on which ROM to pick every 6 hours.
But I want the option to get rid of the ****, yes, ****, they put on this phone. Why they load junk I can't get rid of is beyond me.
If we can't control the phone, I'll have to jump off the Samsung bandwagon next year...no matter how good they make it.

So I've had this thought about this locked bootloader problem. I am not sure if this is a viable solution or whether it would even work. I was thinking that our European brethren has an unlocked bootloader. Would there be a way to Odin their bootloader on our devicesor would the fact that they have a different processor be a problem. Because in theory if we had a Samsung sign Odin file of with an unlocked bootloader we should be able to Odin and have a unlocked bootloader, no? Or is there more to it than that?

Good question. But no, it would not work. Not even because it's a different processor, which that is part. But say if T Mobile got an unlocked bootloader, it would not work for Sprint. Nor would it necessarily help to know how it happened and use it as a road map to unlock another carrier's bl.

I have the firmware for the Chinese model s7 edge it is the closest match to ours and the firmware will not load in odin. It checks against the model and csc codes so we couldn't even cross flash with t-mobiles firmware. I have the bootloader posted over in t-mobile forums and a few people are poking around to see what can be done. Unfortunately bootloader and hardware hacks are nothing I have ever done before.

YA 4.4.2 Bootloader Discussion

Hey there remaining Verizon S3 users!
Coming from my favorite device the T959V this has been quite a trip. This device's bootloader is seemingly impossible to unlock on the 4.4.2 NE1 firmware.
I've got a slightly modified Superlite rom rolling with SafeStrap already strapped. And it is great to say the least. Added some initd and utilities. Evie launcher is pretty nice btw- recommend a try :good:
However. I still really want this thing to be unlocked. The T959V has multiple working Fro, GB, ICS, JB, KK, L, M, AND Nougat ROMS. Totally different devices yes but-- even the newer S4-S6 have cracked loaders now.
There has to be a special way to change this things firmware.
Right now I have 2 ideas to throw out to the wind-
1- Would be that there could be a way to trick the device into thinking it is receiving a new update. Maybe somehow with CSC or something. Also I saw a file named authorized.xml and was reading through to find traces of knox. Would unauthorizing knox strings somehow render it useless?
2- I was reading a suggested post about AVB boots and how they can be resigned on devices such as the Google Pixel and allows the newer patches to still install. Including what was described as a forced re-sign method.
--- Could we somehow resign the bootloader on our device so as to gain control of it? Has anybody tried anything like this since around 2015?
I'll gladly talk about all of this more whenever I feel like popping on- and atm I have no web besides this service. :silly: so no DOS updates and no shiny linux for now.
Gladly tell me that it is "impossible" but I'm not asking that. I'm trying to add some ideas to possibly do the impossible.
Edit: This seems to be an interesting lead on emmc cracking this device. It's probably why people in other threads were in search of a "dev" edition.

I've been around this and many many other forums for years now. If there was an unlock method it would of been found years ago. Devs have long moved on from the old S3. I still have my S3 lying around, bootloader unlocked but I really haven't messed around with it for quite a long time now
And yes the dev edition would of been nice had someone actually had one, it would of of course made it easier to crack the bootloader option maybe. I don't know much about the ins and outs of the device but I know many are permanently locked and will probably never be unlocked.
As far as certain other Samsung devices being unlocked those are far and few between. VZW got smart and started just locking them from the start. This is a huge reason why I left Verizon. The S3 was my last device on big red. I since have had a Nexus 5 and 6 and now a oneplus 3t. I really don't like locked devices and the ability to unlock them and customize them just intrigues me to no end. Good luck however in finding something that may work, but I highly doubt it will ever be cracked

Ya I expected your negatude Shapes. Already seen that you have been searching but it isn't just some application you run. It's an unknown exploit that I'm sure exists. There are exploits right now that can be considered viral potentially exploiting my device as we speak. Maybe not granted my semi-precautious take on things.
Quadrooter and dirty cow could be used to exploit the S3 and gain access to a quoted "all" physical memory. So I find it hard to believe that things can't work in our favor.
Being open minded here. After all, this is technically hacking your own device. Which--
Got me thinking the other day, becausr I was setting up my laptop proper- could we run a nix distro and poke through the bootloader's parameters via exploitation tools? Referencing Kali or it's elder BTrack. But I think it is possible and I just haven't gotten around this loop mounting issue.
To be clear, running a distro ON the device. My flat is already running square.

Also a purposely separate post- I'm building a ROM for this locked firmware and the goal is to have some specific updated apps and yet trim it nicely so as to save space and RAM it's mostly stock style-wise but it'd be cool to re-theme it. I haven't gotten things deodexed yet- being I haven't gotten my apktools working proper yet.
Is there anybody left to be interested in this? I haven't posted anything I've made before- usually just keep them lying around for emergency flashes.

I don't think shapes was trying to act negative at all, just stating the obvious. Nobody is going to try to unlock the Verizon S3, it's pretty much a dead end.
The unlock method used on the S5 will most likely work on this phone, but we need a developer CID to rewrite to the emmc as the series chip used on the S3 likely has the same vulnerability. This is what happened on the S5.
If you read some of the other posts (sounds like you have), we looked for an S3 developer edition but had no luck in tracking one down. For one, it's an incredibly old device. Secondly, you'd have to be semi retarded to purchase one as the original unlock method was around before the developer edition was released.
So yes, if you can find a developer S3 this will likely be an unlock method. It tricks the S3 into thinking it's a developer phone and unlocks the bootloader if the method to write it works the same as in the S5.
As for your questions,
1. I think you're underestimating the amount of security that goes into the bootloader itself. If you want to learn a lot about Android security in general, in the Android security discussion section located under general forums, there's tons of info regarding how complex this all is. But basically, in order to send an update patch, it needs to be signed (you can't just fake the signature) and it must agree with the current bootloader. The way the bootloader is written, it simply won't allow a reversion back to earlier versions or it'll abort the boot.
An easier way to think of this is understanding that the changes made are preinstalled before the actual boot. There's no way for us to change this through normal methods as the emmc has to be written to directly. There is no way to do this from download or recovery mode. Wouldn't matter if you flashed it or used and update package, they are essentially the same thing.
So the only way to actually change the bootloader is to write to the emmc directly through use of the JTAG port. This changes the code of the entire bootloader before the boot and the phone will boot up with any version of the S3 bootloader you write.
2. I think I kind of answered that?
Hope it's clear.

Truthfully after being around the forums for as long as I have I'm really surprised there is any interest in unlocking this device at this point in time. There are just so many other options and unlocked vzw s3s are not that hard to come by.
And I wasn't being negative it's about being realistic. Thanks for sticking up for me brother

Are there any updates to this by any chance, I am interested :C
any hope?

Could the bootloader be unlockable after the Oreo update?

I talked to Samsung for about an hour about why the bootloader is locked for the US versions of the S7.( I have a SM-G930R4) Most of the time they gave me the run around but I was able to find out that with the Oreo update ,it may be possible to lock/unlock the bootloader. They didn't come right out and say it but that's what it sounded like to me. They were saying something about a "security issue" that is supposed to be fixed in Oreo,and that it's within the realm of possibilities. Let's hope they weren't trying to make me feel better,lol. I haven't had a nice phone since 2013,and I was pretty nonplussed to find out we got shafted. I have been using Samsung phones since the original Google Nexus,and have flashed/rooted/customized every single one of them. Customization is important to a lot of people,and Samsung understands this. Why'd they have to give in this time? ><
Highly unlikely
Samsung talk out of their rears when you contact them, usually just to get you to go away I find
Well that's corporations in general right? Lol. I don't want to get another phone if I don't have to. I rather like this one. I guess we'll find out in the coming weeks ,eh?
I have a screenshot of part of the conversation,but it seems like I can't post the link or embed it. Basically it was them feeding me a line of garbage about none of their USA model phones having unlockable bootloaders,and I corrected them. They also said that it was Qualcomm's fault but I can't see how. Don't they use their own bootloaders?
I guess I could always try to trade my S7 for a S6 lol.
I don't know the details of why they are locked or who's fault it is, but they're right that none of the USA S7s have unlocked bootloaders (Snapdragon Models)
It's the Exynos International S7s that are unlocked (G930F, G930W8)
Samsung will have the bootloader encryption key, so they could have added a feature to unlock it like they did with the Exynos versions, no idea why they haven't
If you want an unlocked S7 I'd sell that one and get the G930F
They didn't say it would never be unlocked. What I got from the exchange was that it may happen during the next OTA,which I assume is Oreo,or a patch of sorts thereafter. The particular lady I was speaking to implied it was Qualcomm's fault,but I find that hard to believe. I brought up the fact that we're being singled out (for whatever reason) and that customization is quite important to a lot of us.She said "Yes I agree,if you buy a phone it should be yours" So hopefully they do the right thing. I can't very well just sell this phone ,however. It holds sentimental value and was a gift from someone very dear to me.So my only option is ,A) Pray Sammie does right by us,or B) wait until someone hacks it(if it's even possible)
Also from what I've been told and what I've read on multiple forums(XDADev included) our phone carriers pressured Samsung to do it,to cut down on people bricking their phones. From my experience it's pretty hard to completely brick a Samsung. As long as you can get into download mode and flash something via Odin or backup from recovery,it's all good.
I'm running oreo. But soon all carriers will now lock bootloaders latest sprint and Verizon starting , to make it it so no one can change carriers
Not to stir up an old thread, but oreo just rolled out for the sm-g930p yesterday and I noticed that there is the option for OEM unlock. Good news for finally unlocking the bootloader?

No.. That's not what that feature is for. It's in Nougat as well under development options

Gotcha. I didn't have it on here with nougat though, it didn't show up until I got the oreo update. From what I've read around, that's what it was for.

Random thought...Maybe when the Oreo U firmware comes out flashing the BL will work?

When I talked to Samsung about it they hinted that would be the case. They didn't confirm or deny it directly,but the way they put it sure alluded to something of the sort.
lets pray ))
Yea so anyway still locked and I honestly don't even need root. I'll just use the unlocked firmware and disable bloat. Rooting the s7 seems arbitrary at this point. If I wanted to I would just trade my s7 USA varient for an international varient if I was really that adamant. S7's are pretty cheap now with the s8 and s9 out on the market.
I have an unlocked phone and the only thing unlocked is the carrier or sim, nothing to do with the bootloader unless you all are suggesting that after the full release of Oreo on all the s7 devices that they may rethink locked bootloader. By then I'll probably just get a new phone. I've lost interest in rooting the s7 but that's probably because there's only three ways around it. Rooting Android 6, rooting earlier versions of Android 7 or getting the xynos s7. I love Oreo more than root on this phone.
