[AT&T Samsung Galaxy S 5] AptLogic:
lol what modification did you make that borked your phone?
[AT&T Samsung Galaxy S 5] clyde1914:
I just changed the version number.

I wanted to update an app that I installed with an external apk using google play. google play said it's not compatible with my device. I thought this might be because i'm on 5.0, since the app worked fine when I just installed the apk.

So I changed the value to 6.0 in build.prop, that didn't work. I made the mistake of turning my phone off, and that's when it wouldn't turn on :mad:
[AT&T Samsung Galaxy S 5] AptLogic:
Ooh yeah that would do it.
[AT&T Samsung Galaxy S 5] clyde1914:
Alright sorry for bothering you again :o

The steps in the OP worked, and my phone is now working again.

The only thing is it now looks like this -
[AT&T Samsung Galaxy S 5] AptLogic:
Did you flash the pre-rooted OF3 that's in the OP? lol
[AT&T Samsung Galaxy S 5] clyde1914:
Uh, I think so. I made it wipe internal storage before flashing the zip. Did that mess it up?
[AT&T Samsung Galaxy S 5] AptLogic:
Yep. I forgot to put that in the OP but it's a bad idea to wipe the partition that has the files you're trying to flash ;)
[AT&T Samsung Galaxy S 5] clyde1914:
Yep I didn't select internal storage and it worked fine :)

Turns out I even had a backup from this morning on my google account, so everything turned out fine!

Thanks again [MENTION=7597286]AptLogic[/MENTION]! I really appreciate it.
[AT&T Samsung Galaxy S 5] AptLogic:
Anytime. Always happy to help :)
[AT&T Samsung Galaxy S 5] boobopt:
Hi - is it safe to do a software OS update after rooting with the latest method and installing the modified OF3?
[AT&T Samsung Galaxy S 5] AptLogic:
If you mean an OTA update to a different version, its never been tested so I can't make any guarantees, but it would most likely either fail or brick the phone because the newer Samsung Kernels don't allow root.
[AT&T Samsung Galaxy S 5] samccfl99:
Sorry, no. That is how many people lost their root in the beginning of this phone (if they had it) by taking a LP OTA, which in those days changed the BL from KK to LP and then got stuck. Until now.

See, it only took 2.5 years to be able to get to where we are, thanks to many people including the ones in this thread.

See, I can be nice...
[AT&T Samsung Galaxy S 5] boobopt:
Thanks, got it. So I'm guessing in order to update beyond 5.0, we need to wait for an updated modified version of a later release?
[AT&T Samsung Galaxy S 5] AptLogic:
I doubt it will happen though because Sammy's kernels are really particular.
[AT&T Samsung Galaxy S 5] samccfl99:
Or Odin Unrooted Stock MM-PH2. At least then you would have Wifi Calling/SMS. I can't live with Stock.

I am hopefully going to get a S7E when the S8 comes out sometime in April (so they say), but I really would like that S8. The G935-F is now $562 new. Maybe will get near $500. I still am not sure if those custom roms will be as pretty as my TMS5 though...:D
[AT&T Samsung Galaxy S 5] AptLogic:
I wonder if there's some way we would be able to port WiFi calling over... that'd be a cool thing to look into after I finish most of the major work on AptOS.
[AT&T Samsung Galaxy S 5] NavSad:
The source is out there because cm has it already.
[AT&T Samsung Galaxy S 5] AptLogic:
Well if CM has it already it shouldn't be too much of a hassle to get it on a TW ROM.
[AT&T Samsung Galaxy S 5] samccfl99:
It does work on a TW rom. Its called MM. MM stock, that is...:D

I do not understand why they could not just fix it in the towers or whatever so wifi calling/sms just works, but that is what ATT has done, and of course I do not know what I am talking about, above my paygrade...:laugh:

Rather someone work on the BL, which I know probably will never happen on this phone, hence the G935-F wish!
[AT&T Samsung Galaxy S 5] johnkirchner:
I would assume it needs it on the firmware, not the tower. Tower won't care if you are using WiFi calling. Personally, I have no use for WiFi calling, so the rooted lollipop is fine for me! Either way, my next phone will NOT be carrier branded and will have an unlocked Bootloader. Just need to save up for it now, lol
[AT&T Samsung Galaxy S 5] NavSad:
This looks interesting:

SVE-2016-7930: Multiple Buffer Overflow in Qualcomm Bootloader

Severity: Critical

Affected versions: Galaxy S5 with Qualcomm AP chipset

Reported on: December 20, 2016

Disclosure status: Privately disclosed.

A buffer overflow vulnerability exist in Qualcomm bootloader.

The patch prevents buffer overflow by removing the problematic source code.
[AT&T Samsung Galaxy S 5] 719c6:
Anything here you can use? Wikileaks Android CIA stuff
[AT&T Samsung Galaxy S 5] AptLogic:
It was privately disclosed, which means the manufacturer (Samsung) was contacted directly about this vulnerability, and nothing relating to the vulnerability or how to recreate it was released outside Samsung.

We know the vulnerability exists, but we have no idea how to exploit it. We don't even know what it DOES.
[AT&T Samsung Galaxy S 5] AptLogic:
I have an idea for Marshmallow root...

What if we created a shell script that runs at or after boot (as the system user) that automatically injects SuperSU and the SU binaries, and then removes it when the system shuts down?
[AT&T Samsung Galaxy S 5] Duckman5:
Actually writing to the system would be dangerous in the event of a system crash or unclean shutdown. Better to use a filesystem overlay if you already have root. Just have the script recreate the overlay at each boot.
[AT&T Samsung Galaxy S 5] AptLogic:
What utilities would we need to get a filesystem overlay working on boot?
[AT&T Samsung Galaxy S 5] Duckman5:
I'm not 100% positive what the S5 kernel supports, but Linux in general supports several different filesystem including UnionFS and OverlayFS. Reading through the docs for OverlayFS it looks like all you need is the mount command (unless it needs to call something like mount.overlayfs or something equally obnoxious):

https://www.kernel.org/doc/Documentation/filesystems/overlayfs.txt
[AT&T Samsung Galaxy S 5] AptLogic:
Alrighty, I'll probably be taking a look at this more in-depth through this weekend, we *might* be able to make something out of it.
[AT&T Samsung Galaxy S 5] CreeperPVP:
Just curious, what is OF1?? It looks cool :D (sisters old phone)
[AT&T Samsung Galaxy S 5] mx0_:
Hope not to be a bother, I found this thread after getting the QB1 update and was wondering if it was still safe for me to attempt rooting my G900A. The previous people in the thread who downgraded from 6.0.1 were either on PH4 or were using the Active.
[AT&T Samsung Galaxy S 5] AptLogic:
Yeah you'll be fine
[AT&T Samsung Galaxy S 5] CreeperPVP:
Can't we use Mobile Odin to inject SuperSU to the 6.0.1 tar on installation? Or would that not work.. Curiosity killed the creeper -BOOM-
[AT&T Samsung Galaxy S 5] xdanilva:
Development was stopped for mobile Odin in 2014 and this phone is not supported
[AT&T Samsung Galaxy S 5] CreeperPVP:
I feel like if Flashfire works, we can get Mobile Odin to work.

Anyone want to try? Or too much work..
[AT&T Samsung Galaxy S 5] AptLogic:
I mean we can do the same thing with flashfire but the kernel will detect it and throw the phone into a loop
[AT&T Samsung Galaxy S 5] CreeperPVP:
If i knew where all of these Engineering Kernels for the S7 were coming from maybe we could get some work finding some for the S5. But then again the s7 IS newer.... So it might not work :/
[AT&T Samsung Galaxy S 5] AptLogic:
Pretty sure they're coming from leaks from Samsung, which really pisses me off because if they can get them for every device BUT ours, why can't we get some?
[AT&T Samsung Galaxy S 5] xdanilva:
[MENTION=7597286]AptLogic[/MENTION] it's probably corporate at&t's deal or something like that
[AT&T Samsung Galaxy S 5] CreeperPVP:
I wonder if the S7 Engineering Kernel leaks are part of T-Mobile's 'deal' hehe.. They did say they were asking Samsung for a method of unlocking "we all could agree on" or something to that extent. I found this but i don't entirely trust it as you have to pay to download.. But it's OI2 (possibly 5.0 testing)?? https://easy-firmware.com/index.php?a=browse&b=category&id=12280 i don't know.. you tell me what you think.... The website address even seems sketchy..
[AT&T Samsung Galaxy S 5] xdanilva:
COI2 is Android 5.1.1 for the Samsung Galaxy Note 4, so no it's not a engineering firmware, also if you look for a little bit you can find a proper download.

[MENTION=5705451]CreeperPVP[/MENTION]
[AT&T Samsung Galaxy S 5] AptLogic:
OI2 is also an engineering firmware for the S5 (I think it's 4.4).

Don't pay for it though, I got it and I can upload it tomorrow.
[AT&T Samsung Galaxy S 5] xdanilva:
[MENTION=5705451]CreeperPVP[/MENTION] also what I mean by "deal" is that at&t is corporate as ****, so corporate they protected their bootloader
[AT&T Samsung Galaxy S 5] AptLogic:
When you think about it the bootloader isn't even THEIRS. All they do is resell the phones at a "lower" cost which usually costs 2-3x more than the retail price.

They're just crooks in the end.
[AT&T Samsung Galaxy S 5] EthoDream:
Do you guys know if there is a root for the S5 Active on 5.0 OF3? I followed this guide:https://xdaforums.com/att-galaxy-s5/general/guide-downgrade-s5-active-mm6-0-lp5-0-t3523683 that showed how to downgrade the Active from 6.0 to 5.0, and then you can root. Is this perhaps an outdated article? Is there a root for the Active? Should I go back to 6.0? If anyone can answer these questions for me, that would be most appreciated. I really want root on this phone.
[AT&T Samsung Galaxy S 5] AptLogic:
You could try the other method at the bottom of the OP, but it may softbrick so keep that in mind.
[AT&T Samsung Galaxy S 5] EthoDream:
But is there currently no root for the Active? And how close are we to getting one?
[AT&T Samsung Galaxy S 5] AptLogic:
There currently is no root method that works consistently with the Active. This is because we do not have an engineering firmware for the G870A. If anyone can find one (something along the lines of "COMBINATION_ATT_FA44_G870AUCU4AXXX"), we could get root going for it.
[AT&T Samsung Galaxy S 5] AptLogic:
And there's our problem.

See, I checked GemFlash for the files a while ago and they weren't there. And generally if GemFlash doesn't have it, nobody does.
[AT&T Samsung Galaxy S 5] xdanilva:
would one of the roms here work? https://www.androidfilehost.com/?a=show&w=files&flid=27720
[AT&T Samsung Galaxy S 5] CreeperPVP:
Be cool if we could flash firmware from other carriers lol.. But I guess that's only limited to s6 and s7 for the moment
[AT&T Samsung Galaxy S 5] AptLogic:
No because any KitKat firmwares you try to flash are on AUCU1 and you'll get a qfuse error.
[AT&T Samsung Galaxy S 5] AptLogic:
If someone could provide a little help... my WiFi won't connect to any DHCP networks, it just hangs on "Obtaining IP Address".

Now normally I would just switch to static IP but I don't know the configuration for this network. I've tried wiping the cache and the /data/misc/dhcp folder but it doesn't help...

Any suggestions?

Nevermind, fixed it.
[AT&T Samsung Galaxy S 5] StiflingHat9897:
Marshmallow (PH2)

Just making sure before I go ahead and try this, will this work fine on PH2 without a brick?
[AT&T Samsung Galaxy S 5] AptLogic:
If you follow the full instructions you will end up on OF3, but yes.
[AT&T Samsung Galaxy S 5] StiflingHat9897:
Thanks! I'll go ahead and try it tomorrow when I get home
[AT&T Samsung Galaxy S 5] StiflingHat9897:
Is there any way to update to marshmallow? I tried flashing the firmware with flashfire, but the keep root or whatever failed
[AT&T Samsung Galaxy S 5] AptLogic:
No it's not currently possible because the Marshmallow kernel will panic if it detects root.
[AT&T Samsung Galaxy S 5] PigLickJF:
I've been wanting to do this for a bit and haven't gotten around to it yet. I'm currently on PH4, but my phone just today notified me of an available AT&T software update. If I allow it to update is there a chance it will interfere with the ability to root with this method?

Also, to be completely clear, can I just follow the instructions in post 1, or do I need to use post #2 to downgrade first, then follow #1 for root?
[AT&T Samsung Galaxy S 5] AptLogic:
The OTA update SHOULDN'T pose a threat to rooting, but be vigilant!

And you can just go ahead and do the instructions in post 1, it'll get all the downgrading done for ya :)

Remember to back up your important data!
[AT&T Samsung Galaxy S 5] AptLogic:
TO EVERYONE ASKING IF WE CAN UNLOCK THE BOOTLOADER YET:

This is the question I get the most, and unfortunately it's also the most

annoying

For the LAST TIME:

YOU CANNOT UNLOCK THE G900A/G870A BOOTLOADER!!!

This means no CUSTOM RECOVERY OR CUSTOM KERNELS!!!

Anyone else who says it can be done is either uneducated or lying, any other time I see this question asked I'm linking this post.

If of course this status updates I will change the contents of this post accordingly :)

Thanks for flying AptLogic
[AT&T Samsung Galaxy S 5] johnkirchner:
Unfortunately some will still see this post and create a thread asking. :rolleyes:

Think it would be worthwhile to create a new thread with up to date info like this, differences between sim/Bootloader unlock, etc and see if a mod will sticky it?
[AT&T Samsung Galaxy S 5] samccfl99:
Well the phone is what it is. It is still a darn good phone, having a sdcard and a removable battery. And thanks to the find of the OF1 tar, one can try MM or go back to a better version of LP, namely rooted 5.0. I really do not know how people live/lived with that 5.1.1. I know someone who has a cheap LG Tracphone (yeah, I know...LOL) that I setup and played with and those options in that particular 5.1.1 are very lacking and whack, but I know all manufactures play with their versions of Android.

The S8 will be coming out soon (Apr or May maybe). I so do want one, but it is going to be very expensive to get an international version of the phone (or even in monthly payments if you get it from your provider). Right now a new G935-F (S7E) is $545 (many places on Ebay). Hopefully that will go down more soon after the S8 comes out. The only thing I do not like about it is that it does not have a removable battery. Seems like it is very hard to find a good new phone with a sdcard and a removable battery these days.

My G900A will be 3 years old this June. If I replace it, then I could and will try the OF1 to see if it works. I do not have any reason to doubt it reading some of the posts here.

It's too bad we will never unlock the BL, pretty much the only version of this phone that still has it locked down (thanks ATT). I doubt we could ever get to N without one (or is that old now too?). There seems to be a lot of choices for the S7 in the rooted rom department, including N-based roms. Do I really care? I did not even go past 5.0. I just need good battery life and root. I do not need a lot of fancy bells and whistles (except a good custom rom...LOL).

HAVE A NICE WEEKEND ALL
[AT&T Samsung Galaxy S 5] junnelle:
But we still have hope for MM to get rooted, right?
[AT&T Samsung Galaxy S 5] AptLogic:
No
[AT&T Samsung Galaxy S 5] samccfl99:
Allow me, please. NO...LOL, not for this phone. They still cannot even root LP without coming from KK on this phone and staying below 5.1.

MISERABLE ATT...

Answer: UNLocked BL phone...Sorry...

AT LEAST NOW YOU CAN GO TO MM FOR FUN AND GO BACK TO ROOTED 5.0 THANKS TO THE OF1 FIND!
[AT&T Samsung Galaxy S 5] AptLogic:
I just remembered we can do what they do on some Verizon S5s and put some mods into MM, we just can't have root/xposed
[AT&T Samsung Galaxy S 5] samccfl99:
Just put your talents to another phone. Actually this model is over 3 years old now and is an antique even though it is still a good phone. Hard to believe ATT got $649 over time for this phone...
[AT&T Samsung Galaxy S 5] pinheaD420:
Ya don't listing to this fella ....Keep your efforts right here ....
[AT&T Samsung Galaxy S 5] AptLogic:
As of now, I'll be mainly supporting this device until late October, and then after that I'll be doing "secondary" support for about another year, which basically means updates will come at a much slower rate.

Now you may be wondering why... well my contract with AT&Crap ends in October, and I'll be moving to T-Mobile and getting either a Honor 5X/6X or a OnePlus 3T/5.
[AT&T Samsung Galaxy S 5] jep971:
Apt you are awesome. I have had this phone for 3 years and hated it. Now I like it. Still reading to figure out how to update kernel after romantic flash but have more reading to do. (Romed last night and had to put 5.0 rooted on so I could have a phone at work today.) Will work more tonight
[AT&T Samsung Galaxy S 5] jep971:
At work without Odin... Will Alliance romv8 Work with the Kernel as is? or does it have to be OC4? Just thinking about trying but have 5 hours of work left without anyway to fix it until i get home. thanks for you help!

Yeah Alliance V8 should work with any 5.0 kernel.

Hi [MENTION=7597286]AptLogic[/MENTION] can you tell me how to install viper4 for this rooted device after following OP instructions. I tried istalling viper several time with no success or status abnormal and unsupported.
[AT&T Samsung Galaxy S 5] AptLogic:
Use DivineBEATS instead of Viper. It is confirmed to work and it has the same features as Viper and more.

Welcome to the XDA Forums, zzsero7!

Yes, your phone is compatible with the root method. But please be aware that it will wipe all of your data, so make sure to back up anything important before beginning! :)

[MENTION=7597286]AptLogic[/MENTION]. If next time we want back to PH4 again.. is there any method to flash PH4 rom?
[AT&T Samsung Galaxy S 5] zzsero7:
I am so happy rn

ALRIGHTYYYY i SUCCESSFULLYY got root on my phone!! now i want to switch my rom to the twisted lollipop rom. I wasn't sure if i do the i wasnt sure if i do the Rollback steps or not before going to the new rom steps. Can i skip over the COI rollback steps and just move on to the custom rom steps? also if AT&T issues an update, should i update or leave it alone?

Ps YOU ARE MY FAVORITE PERSON RIGHT NOW thank thank thank you so much i thought i was stuck with a phone without root :) so happy

EDIT: Id like to say sorry for being dumb when tired lol. Thank god i waited (although it wouldve done no harm) i realized that rollback wasa rollback to the stock base of android. This message can be disregarded except for the ps part lol

I also got a custom ROM on it :3 thanksss so muchhh
[AT&T Samsung Galaxy S 5] AptLogic:
Yeah all you have to do is flash PH4 in ODIN and you'll be back :)

Glad you got it to work :D we all do weird things when we're tired (coming from the guy who is usually up till 11PM doing ROM stuff :3)
[AT&T Samsung Galaxy S 5] taadow1030:
Hello all. 1st, thank you to [MENTION=7597286]AptLogic[/MENTION] for providing us AT&T users with Root access & ROMS. I have read the OP and the last few pages of the thread.

Forgive me for my ignorance, as I'm new to this aspect of rooting as regards the locked bootloader. I've rooted and installed ROMs and kernels on multiple phones, but all had either TWRP or Philz recoveries.

I see that we can use xPosed framework and Lollipop ROMs. Is it possible for us to use some of the newer AOSP ROMs if we don't enable root?

Ideally, I would like to have multiple ROMs in my sd card and be able to quickly backup and restore on the fly.

Best case scenario:

-Stock debloated marshmallow rom - no root

-Alliance Lollipop with xPosed and root

-Marshmallow AOSP without root or Lollipop AOSP with root

Is this at all possible? I'm nervous about rooting this phone as it is still under warranty.

Any advice someone could provide would be sincerely appreciated.
[AT&T Samsung Galaxy S 5] inspired55:
Sorry can not use an aosp rom with your locked bootloader it's a kernal issue. And you can run non rooted stock Roms but wouldn't beable to flash backups. You have to use odin to flash non rooted Roms. Hope this helps

SM-G900T Powered by Phoenix
[AT&T Samsung Galaxy S 5] taadow1030:
Thanks for advising. I apologize for all of the questions. So, I can use flashfire to flash the ROMs that have been confirmed, Odin to flash the kernel if necessary, boot the ROM , set it up and then make backups to restore later from my sd card? I used to do this via twrp, but I'm unsure if I can backup/ restore safely with flashfire due to the bootloader.

Edit: can we use the aroma installer for xtrestolite?
[AT&T Samsung Galaxy S 5] AptLogic:
Yes you can use the Aroma installer for XtreStoLite, but you should probably consider using X ROM instead, it has the same features as XtreStoLite, but its smaller, more stable, and is receiving support updates as needed.

https://xdaforums.com/att-galaxy-s5/development/rom-xtrestolite-g900a-edition-extras-t3525205

If you are looking for something more on the AOSP side of things, I invite you to help test AptOS, which is currently in Pre-RC. Or, you can wait for the final release which will be sometime next month (an exact date has been chosen but will remain confidential at this time): https://xdaforums.com/att-galaxy-s5/development/aptos-t3564641
[AT&T Samsung Galaxy S 5] taadow1030:
Thanks so much for your help and advice. I have a fast setup (used package disabler) and I added other mods like Ogyoutube (screen off playback) , Flytube (pop up youtube), dns66 for ad blocker and Samsung Good Lock. Is the difference between modified non-related stock and custom ROM that different as regards performance and battery? I don't know if I'm trying to talk myself into rooting or out. Lol
[AT&T Samsung Galaxy S 5] AptLogic:
Well I can tell you that X and AptOS have only a fraction of the apps that a stock install has. I had to restore to a stock build earlier today to grab Snapchat and it was SO SLOW.

Also I had the phone plugged into my PC and the battery was still running down soo I'd say go for X to start with and if you think AptOS is a good fit for you instead just jump on over. (and did I mention AptOS has Xposed pre-installed? ;))

[AT&T Samsung Galaxy S 5] samccfl99:
Where in the world are all these G900A's coming from? They started manufacturing them 3 years ago. If you want to get an S5, one should get a G900T, which works fine with an ATT sim card. It has an UNlocked BL, just no Wifi calling/sms. You can then install a custom kernel and do many things.

But for the people who may have got their phones with an LP BL, then this thread has helped with the find of the OF1 tarball. As I always say, it is still a darn good phone, even if the screen is only 5.1". Was the fastest phone around in it's day and still not bad. Mine will be 3 YO in June, but has been rooted since 10/2014.

I still check this thread in the almost miniscule chance that the BL would be unlocked, but ATT kept a good job hiding a Development copy of the firmware, unlike Verizon.
