Is a Bump like exploit possible on the Verizon S5? - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

As an owner of a rooted Verizon Retail S5, I'm very grateful for the developers that have worked hard to maximize the potential of the phone, but no matter how much you clean up TouchWiz, it is simply no replacement for Cyanogenmod/AOSP. My question is it possible to have a work-around for the locked bootloader like the LG G3's Bump possible on the S5?

I would also love to see something like this. I had mentioned in another thread why not try to use Kexec? That was used on a CyanogenMod ROM I had on my Motorola Droid 4 that had a locked bootloader. Basically, the phone will boot with its kernel, then kexec will load the custom one on top of it.
Now granted, IDK if the Motorola D4 had TrustZone or any of that nonsense to deal with so I'm not sure if something like that could work as an interim.

[Q] Likelyhood of development on Razr M?

Greetings, programs! Well my question is not likely something anyone could have a definitive answer for - but I welcome any opinions or ideas. I don't want phone that is locked up against tinkering, but the current "price" of this phone is so tempting. Just about everything I've read tells me I'd really love this phone - the only thing holding me up is my expectation that there will be little to no development done with this phone.
I see that the bootloader seems to have been successfully unlocked? Now that this is the case I wonder if it's likely to be something anyone puts work into as far as developing ROMS/kernels. I'm not expecting Nexus-level activity, but even the hope of something might help me make up my mind (or I may just get a GNex). Thanks,

The boot loader is unlockable for the dev edition RAZR m and as for development, safe strap has been released and cm10 alpha has been released. I have no doubt that in the future, more will come out. If ur attracted to this phone, then I highly suggest you get it because of the size and specs.

Totally agree with jarzy00 i am coming from evil land apple and this phone feels nice and compact replacing my i4 LMAO
Razr i, Razr M and Razr M XT905 (Future release for Euro market maybe) are one of the few phones left standing with this kind of small foot print.
ever one else moved on to larger screens. And the specs aren't too shaby =)
Ok, I see. My experience with Moto phones are limited, but do I have it right that using the bootstrap method you can flash custom ROMS, but custom kernels are a no go? Still waiting till I make a decision, but every bit of info helps.
Coorect Bootstrap allow you to load that Beta CM10.
(There isn't much support on that yet)
And no custom kernels unless you have the Dev edition
There are AU Edition, US Edition, Dev Edition, And the i (Intel), there are plans for a EU Edition which will be GSM only
Either get it and hand in tight, or look for a DEV

Not sure how far development is on Safestrap for the M, but it will allow custom kernels on locked devices using kexec. The version for the Droid 3 (which has a locked bootloader) allows a 3.x kernel to be run instead of the factory 2.6.x kernel in order for better ICS and newer compatibility. Unless Motorola has patched this kexec bypass then it should be possible to implement on the M.
Thanks guys for this thread. I was possibly looking at this phone, but I don't want to end up with the same situation we had with the bionic. I think I'll skip it until Moto wises up and unlocks the bootloaders.
If you really want some development here, look at the donate thread for getting nytro a razr m so he can develop for the retail version. In terms of safestrap, you could potentially get modify a custom rom. It just takes one rom to iron out the major bugs and people can start deriving from it.
i dont think moto will ever get smart with bootloaders, which is sad because they make quality phones, with unlocked bootloaders i dont think id ever buy another brand. but regardless, we have stable safe strap, just isnt a big flagship device, its not a new phone and with all the new better phones that are cake to unlock, this phone is just looked over and left in the dust, aside from a few very good devs we have working to give us some stuff to play with, we wont see much.

[Q] Unlock, root, bootloader??? Huh?

Let me apologize for how horribly informed about phones I am even though my study is in a related industry (I'm a computer science undergrad), but I just don't understand all the different terms well enough to draw any proper conclusions as I research my way on getting a Galaxy S4. (I will be getting the Fido S4...so I'm guessing the i337?)
So let me get this straight:
Rooting gives you root access, as with any *-nux systems. So it means you'll have full control of your phone.
And as far as I can tell, only some variants of the S4 are root-able at the moment
Bootloader (lock/unlock) is whether or not you can put in a new (custom) firmware or not.
And so far, it looks like most variants are locked in terms of the bootloader.
Unlocking, I'm guessing in most occasions mean SIM-unlocked right?
What I don't understand is if a device is rooted and flashed with a new ROM. Does that effectively also unlock the sim lock?
Sorry for the weird questions and I know it doesn't seem like it's really S4 related, but I'll be getting an S4 soon so I thought it'll be a good idea to ask in here. More to the point, I'm worried about what it takes for me to get my new phone to the most potential. One thing I'm most concerned about is the SIM lock because there is a good chance I'll be traveling with this phone.
Thanks in advance for any answers.

Verizon S5 - Quick help please

Can anybody please help with a quick answer?
In a nutshell I still torn between the S5 and HTC M8 (buying tonight) and needed to know what I can do with the S5 as far as root and custom ROMs go.
I think the S5 is better than the M8 however the locked bootloader plain sux and there are plenty of recoveries and ROMs for the M8.
I certainly prefer the VZW S5 if I can at least root it and maybe install a custom rom or even plain KitKat if needed. I can always wait for a custom recovery.
Is that possible as of now?
Thanks in advance!

If you really like rooting your device and such, i suggest the S5.
I believe there are recoveries available but currently there are no plain kitkat roms for the S5.
HTC has all these S-on, locked bootloader and stuff that makes it a hassle to root.
It is also a hassle to return HTC devices to factory spec.
Hardware wise I think the S5 is a better choice. it isn't stupidly tall, doesn't have on screen keys, doesn't have an exterior that scratches and dents, doesnt have a 4MP sensor that performs VERY inconsistently.
I'll admit HTC has better software, but software can be changed, hardware cannot be changed.

Thank you, I liked the HTC but got the S5 for the same reasons you pointed out, however is Verizon version and as far as I know there is no root for it yet.
Well I believe it will be unlocked at some point...just need some patience.
Thanks again!

Just purchased a MXP and have questions

While I wait for the arrival of my MXP I have some questions for the community so that I can hit the ground running. First thing, I'd like to unlock my boot loader but I was just curious if there is a way to re-lock it afterwards just in case I need to send in for repairs or something along those lines? Also wondering about VOLTE support. I see some roms that state they have it working but is this a stock feature or do I need to use a custom ROM to get VOLTE to function? Also is there any known method of rooting without unlocking the boot loader just in case re-locking it is not possible? Thanks for the help everyone.
I am coming from a g920a. That phone is torture for someone like me who likes stock Android and rooted devices. Probably the worst phone I have ever had. Can't wait to get my hands on my MXP and leaves this piece of junk behind!
I'm on Verizon and I can confirm it supports advanced calling, which is VoLTE as far as I know but it might require turning it on at the provider level.
Sent from my XT1575 using Tapatalk
I haven't messed with VoLTE yet so I can't answer those questions, but as for your others: The bootloader can be relocked, but the unlock method involves submitting an unlock request code to motorola, and they immediately email you an unlock key, along with a warning about voiding your warranty, so even relocking it does not unvoid your warranty. HOWEVER, it only voids your warranty for software issues. If it's a hardware problem unrelated to the bootloader being unlocked, they'll still handle it, and accidental drops and things are still covered if you buy an accidental damage warrenty. Also, as far as I know there is still no way to root without unlocking the bootloader.

Whoops, yeah I guess they fixed it down the line. Sorry, I've been enjoying stock+xposed too much to follow custom development.
Edit: also root without bootloader unlock will likely never happen. We have a root method already, so there's no incentive to find another method.
The answer you seek was right in the first page of this forum....
http://forum.xda-developers.com/moto-x-style/general/moto-x-style-how-to-unlock-bootloader-t3192140
That being said, I would consider waiting until after Marshmallow drops before you unlock your bootloader so as not to interfere with any OTA's. Conventional wisdom is that it is coming within the next few weeks as the "test drive" has already started and a "soak test" should follow shortly.
yeah i know it can be unlocked I already read that post. I would not have gotten this phone if the boot loader was not un-lockable. That's the whole reason I am moving away from my AT&T Galaxy s6. I was just trying to clarify if re-locking made any difference as far as the warranty is concerned. I appreciate the answers guys. Just trying to determine if I should keep it stock or use a custom ROM out of the box. Sounds like I will go stock for the time being. Now as far as unlocked boot loaders interfering with OTA's? Is this really a thing? And wouldn't somebody just post the OTA image on the forums when its ready anyway?

Well as to it being a thing, I certainly can't say for sure. But what reason is there to unlock the bootloader if you're not going to root? And once you do that, you almost certainly will not get OTA's. What am I missing? Is there another reason you are looking to unlock?
The one thing I don't know is if there a some type of a "tamper flag" that would require something like triangle away.
You don't think you could just do a fastboot oem lock?
Sorry to give you the wrong impression but I fully intend to root and also install Xposed and all that good stuff. There are a lot of things I need that require these things such as BubbleUPNP's audio cast feature, and of course the all powerful AdAway and YouTube AdAway in addition to Titanium Backup and Viper4Android etc. I normally use that stuff every day and so dealing with my last phone was like living in Android Hell. All the great hardware but software that was hopelessly mangled un-rootable and just sad for such a powerful device as the s6. Being able to have these things back is my number one reason for buying this phone so you best believe that's the very first thing I will do once it comes in lol. The only reason I am so concerned about the warranty is because I have needed it in the past for several other devices and so don't want do something that is un-doable. But from the sounds of it this will only affect me if the software causes the defect and I am fairly confident I can fix anything software related all by myself. Mostly only concerned about hardware defects and if they will still be covered that is just perfect.
And already I am feeling the difference here in this part of xda. The forums for the g920-a are like calling out into the dessert, and in no time at all you guys have address my major concerns. Thanks again

I'd still recommend waiting at least a couple of weeks to see if Marshmallow shows up!
I'm coming to the MXPE from a OnePlus One which I have to say was one of the funnest phones I've ever owned. I wasiunlocked, rooted and flashing CM12.1 nightlies about twice a week.
I thought I would miss it, but so far so good on the MXPE without rooting. We'll have to see what happens after MM drops. I'd like to get it rooted, but I haven't done nearly the amount of modding you've done.
Good luck with your phone. I can honestly tell you it's a really nice device!
While its tempting to wait for marshmallow to show I cannot live without root any longer. I have already been without it for months because of this damn s6. I'm sure someone will upload the OTA as soon as it's available so I'll just flash it when the time comes.

Well if you're an xposed user you should root immediately with no concern about the 6.0 OTA, since xposed doesn't work on 6.0. I'm not moving to 6.0, myself, until xposed is released for it. I use xposed modules everyday and am not giving it up, not even for doze mode.
That's kinda how I am feeling as well. I can achieve similar results to doze with the xposed app amplify with enough tweaking so its not a big deal.

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!

Hey bud, thanks for getting the ball rolling on these questions. If you could add some more information, I'd appreciate it :
If we still don't have a way to Root or Unlock bootloader, how are these ROMs (Echo, Tek, and other stock ROMs) available with root? And how are these flashed? Are we somehow bypassing the BL by using FlashFire?
Can you also educate me on the U Firmware and why people install it and is it reverseable?
Lastly, if I got a T-Mobile variant for example, installed these ROMs Tek, Echo, etc, can I return to Stock completely and return to T-Mobile, by any chance for them to take it back? Thank you again!
for the t mobile variant, I was able to flash the U firmware and flash back to stock t mobile. NOTE: I did not flash the U bootloader. I kept the T mobile bootloader just be sure I could flash back to stock t mobile(APK1). I'm sure this method would work with other carriers as well. so what ever variant you have, make sure you stay on that BL and only flash the U firmware CSC and AP. As for the CP(modem) I would flash your carriers latest CP file. That's what worked best for me with the U firmware. Currently I'm using the latest nougat BETA
Thank you very much for your response, bud. One last follow up question: Since all the US variants are rooting based on the ENG Kernel, is there really a benefit of getting one variant over another, for rooting or etc purposes?
P. S. May I ask why you flashed the U Firmware? What are the advantages of it? ?

The u firmware basically does not include all of the software that is usually included with the phone. For example.. Tmobile with their software on it, Verizon att etc... Makes the phone a bit snappier especially if you were to root. Even tho I hope for a more stable root still. I am rooted at the moment. Wish they didn't recall the note 7 because the root on that was better

You're confused. At least, you were.
We do not have an "unlocked Bootloader" and we never did. We had an engineering kernel. That engineering kernel allows certain commands that enabled us to acquire root access. But without that kernel, the system (with the original kernel or boot partition) checks for any changes in the /system partition. If any are found it triggers a bootloop. So basically, if you want root we MUST have the engineering kernel. Unless someone else finds another way that's just the way that it is.
Personally, I unrooted and went back to stock. Root was okay at first but with the lack of development, Samsung Pay and the fact that Android 7+ will probably not be seeing root... well... time to accept the fact that Samsung owns the phone even though we bought it. What else can we do?

Thanks for your helpful responses fellas. I understand root is not perfect, but for some folks like me, Xposed seems to be worth the trouble. For Samsung Pay, I intend to use the Gear S3 one day ?.
Final question, since all US Snapdragon models are using the engineering kernel to root and etc... Is there a benefit of getting one carrier variant, over another? For example, Verizon is usually the cheapest. Is it wise to get that, with the U Firmware, to use on AT&T? Thanks!

Let me know if that works out for you then.
I just purchased the S2 Classic (on T-Mobile) and use Samsung Pay quite a bit. But I can tell you that it does open Samsung Pay on the phone and if you are rooted, Samsung Pay will not work at all. So I'm not sure if it will work at all for you even with the S3.
In regards to your other inquiry, I haven't tried the U firmware. I read something about data issues, no wifi calling (which is pretty important to me), no hotspot (which is also really important to me) but I heard that it is really fast. Not sure how much of that is still a problem but you should probably read up on it before doing anything first. But the rooting method is all the same between carriers I believe. All require the engineering kernel and breaks Samsung Pay along with a couple of other apps.
Just make back ups, have a stock firmware available to flash with ODIN just in case and remember that it's almost impossible to brick this device (because we don't have an unlocked bootloader.)

Thank you again for a helpful post. So the S3 has a dedicated MST/NFC chip in it, that allows for Samsung Pay to work from the watch, it's done through the Gear app. That's what I have read.
About the rest of it, again, curious to see if there is one US variant, superior to another in terms of Root capabilities or bands and radios available and etc? Can anyone confirm this for me?
Thanks!

Thank you again for a helpful post. So the S3 has a dedicated MST/NFC chip in it, that allows for Samsung Pay to work from the watch, it's done through the Gear app. That's what I have read.

So does the S2.
When I was setting up the Samsung Pay on my watch it said that it had to download an update.
Then I went through the setup process through my phone which was from the Samsung Pay app.
You go to "Add card" on your watch and it opens Samsung Pay on your phone.
You click "Next" and it displays your Samsung account information.
Then it takes you to a screen that says "Setup complete" telling you that you're ready to use it and at the bottom says "Add card"
You do that all from the Samsung Pay app on your phone which leads me to suspect that if you root your phone, you won't be able to use Samsung Pay on your watch.
People on this thread that you have to set it all up first, remove the Samsung Pay app on the phone but leave it on the watch. If it's all done correctly then it should work. Just make sure you get it all set up first.
Next thing that I'm going to try is using my watch in "Standalone" with my phone out of bluetooth or wifi range. See if that still works.

About the rest of it, again, curious to see if there is one US variant, superior to another in terms of Root capabilities or bands and radios available and etc? Can anyone confirm this for me?
Thanks!

As far as I know, the U firmware permits use of some other bands that aren't normally used. Not sure which ones though.

Thanks for the correction/education on the S2, bud, much appreciated. I wonder if the rooted phone works with the S3, because Samsung has allowed many other non Samsung phones to know work with the S3? But I could be wrong, I thought it was open like that with the S2 as well, no? Looking forward to your testing, hope there is a breakthrough in there! ?
if you want root and customizability and roms, just don't get this phone. you will be very disappointed with the performance once you root and it gets so much worse with Xposed. not worth it at all, you will have better performance and speed from a 4 year old phone that has an unlocked bootloader and strong development. I mean my Nexus 5 (from 2012) had better performance than my rooted S7. it sounds like you do want roms, and if you want roms then AOSP/Cyanogenmod is the way to go. there will probably never be any AOSP or CM ROM on the QC S7/E so you're better off getting an older galaxy model that does have a great development community and unlocked bootloader. or just get a OnePlus or Nexus or something.

exactly this. except for some reason I thought exynos variants are lacking certain bands/features on American networks. could be wrong.

Very helpful inputs guys, thank you! If I were to be honest with myself, I don't want AOSP/CM/Lineage, especially on a Samsung phone, so unlocked bootloader is not a deal breaker for me. However, I think root is cool for me for doing some SystemUI tweaks, Xposed and etc. Exynos was an option I was exploring, but lack of warranty, no Samsung Pay, and the price are enough to keep me at bay. I think I just need to put my big boy pants on and try to use a phone without rooting it. Something I have yet to do in EVER using an Android phone since about 10 years ago, and I have never ever used or bought an iCrap... I mean... an iPhone !

Get a One+ 3T good development and really nice phone if you want root. Root is dead on Samsung phones and so are ROMs.
So by reading thru this thread, I assume having a T-mobile S7E (G935T) rooting is pointless and really not available the way I'm used to it coming from a Note 4. That's kind of a bummer... I've been using Android and have always had ROOT and all the goodies that come with it. And I recently starting really enjoying my Note 4 with all the cool development in Note 7 ported roms oh well... I wonder if the S7E is enough of an upgrade to keep my interest as stock?
I see there is a G935U firmware, but that seems a bit hit and miss? But I'm just starting to read up on all this... :good:

Believe me bud, if Oneplus 5 or even 3T had an SD Card, I'd already have that phone, but thanks for your wisdom !

You and I both man... The last few years, I have lived off the mercy of T-Mobile and their BLs being unlocked. But Samsung sure done them all in ! Even the International unlocked ones disable Samsung Pay (forever, mind you!) if Knox is tripped, which I believe it is, when rooted and TWRP'd.
As I understand it,
Android pay / Samsung pay is why they frown on rooting now. I can understand it, though I don't agree with it.
The first time someone's financial information is compromised, and they've ever used one of the "pay" methods, on a rooted device the pr nightmare that would ensue would make the note 7 fiasco look like child's play.
"Samsung unsecured device compromises persons credit card information today, while Apple is still secure" I can see the headline.
