Can someone PLEASE upload G900AUCU4COI5 to mega?? No site that has it is working at the moment!
[AT&T Samsung Galaxy S 5] AptLogic:
Is android file host not working?
[AT&T Samsung Galaxy S 5] Helgen:
Yes, it isn't working at all
[AT&T Samsung Galaxy S 5] AptLogic:
Yes, the root method should work for your device. It works for all software versions including the latest 6.0.1.
[AT&T Samsung Galaxy S 5] sfpcservice:
OK thanks! i am on the flashfire portion and am using the 'flash firmware package" option. When i select the combination att rom the bootloaders are greyed out and there is no option for setting the permissions like the guide talked about. Am i doing this wrong? Should I only be flashing the boot/recovery,system, cache, persist, and persisted data?

Thanks Again
[AT&T Samsung Galaxy S 5] AptLogic:
You're supposed to use the "Flash ZIP/OTA" function, not the "Flash Firmware Package" option ;)
[AT&T Samsung Galaxy S 5] sfpcservice:
The zip isn't showing up in flashfire. Ive tried it both on the external SD card and in the Phone storage. Any idea why?
[AT&T Samsung Galaxy S 5] AptLogic:
Try restarting the device... It should be there otherwise the file could be corrupted.
[AT&T Samsung Galaxy S 5] sfpcservice:
Yep, corrupted! Thanks agian.
[AT&T Samsung Galaxy S 5] sfpcservice:
Hey one more question, do any of the custom ROMs include wifi calling? If so which is your favorite?
[AT&T Samsung Galaxy S 5] AptLogic:
I don't think any of the rooms actually have WiFi calling... That feature didn't really make it into ATTs 5.0/5.1 builds.
[AT&T Samsung Galaxy S 5] sfpcservice:
oh man, i like that feature!
[AT&T Samsung Galaxy S 5] AptLogic:
Yeah I did too... Oh well I guess (it's a kernel level thing so we can't include it even if we wanted to)
[AT&T Samsung Galaxy S 5] screate:
Hey, thanks guys, this worked beautifully. Quick question, I am running the pre-rooted OF3 and my phone log defaults to all logs rather than just phone calls, how can I change that?
[AT&T Samsung Galaxy S 5] adam_ky:
we just upgraded our phones and its been a while since i pondered root on the wifes old s5 here.. for some reason her s5 got stuck on of2 and wouldnt take anymore over the air updates.. so its still on android 5.0

Id like to obtain root on it but looked over this method here and downloaded the files.. but the root tool zip you have here popped up malware on my windows 10.

since im on of2 android 5.0 is their a cleaner way to do this perhaps..

or is their a way to gain root with some more clean apps?

[MENTION=3216831]taadow1030[/MENTION] , Ideally I'd want to have LineageOS on the latest android (nougat I believe?)...if I'm not mistaken, I could unlock bootloader and put Lineage OS on, but only for Marshmallow, right?

---------- Post added at 04:58 PM ---------- Previous post was at 04:52 PM ----------

[MENTION=477122]sfpcservice[/MENTION] , if you have a google voice number and use hangouts dialer, that should essentially give you wifi calling.
[AT&T Samsung Galaxy S 5] taadow1030:
Unfortunately, we have no chance at getting AOSP ROMs like Lineage or Resurrection Remix unless AptOS can crack the bootloader.
[AT&T Samsung Galaxy S 5] ebamit:
Ok - I need some help. Not a noob by a long shot, but i'm clearly doing something wrong. A friend gave me his G900A to root - "no problem" says I. I've only done it a zillion times. When I had the S5 I used Odin and CF but instead I followed the steps on the first post. Three times. After using Flashfire to install the stock rooted OF3 phone boots as normal. Join the WiFi network, enter Google account, then I end up on the dreaded Samsung Account "This device is locked because of an abnormal factory reset" message. I can't go any farther. Even if I enter the legit Samsung Account info it fails to move forward.

I've done something stupid, and now I am reaching out for help. What am I missing?
[AT&T Samsung Galaxy S 5] AptLogic:
Flash up to stock OI5, enter the account info during setup, disable the reactivation lock, and then start the process over.

Lemme know if you need any additional assistance :)
[AT&T Samsung Galaxy S 5] ebamit:
So follow the process in the first post, then use flashfire to flash OI5, right?
[AT&T Samsung Galaxy S 5] AptLogic:
No no, from where you are right now, flash OI5 with ODIN, go through setup and disable reactivation lock, and THEN start the instructions in post 1 from the top.
[AT&T Samsung Galaxy S 5] adam_ky:
Is there a prerooted 6.0 rom available?

[AT&T Samsung Galaxy S 5] triode3:
Losing Root at Part 1??

Been using my G5 for a long time, waiting for this post to happen....

Following the steps, and I have rooted a number of phones previously (not this one), and it all goes well, however, when I "Roll Back", (and to clarify, my ROM at that point was a G900AUCU4BOF3 , so I am using the BOF3 Rollback Zip: G900A_UCU4BOF3_ATT4BOF3.zip) it works, but when I then try to install flashfire to go back to the good Ol 5.0, I am denied as I do not have root.

Are we supposed to be installing supersu, towelroot, flashfire on the Roll Back rom? Right now I installed the G900A_OF3 pre-rooted stock ROM, but I can not install flashfire on it. It says this rom is not rooted. I tried just for fun to install towelroot, but it is not compatible with the rom.

Any help would be appreciated.
[AT&T Samsung Galaxy S 5] Cullub:
Did you ever get around to trying this out yet? Sounds promising!
[AT&T Samsung Galaxy S 5] AptLogic:
Sorry for late replies!

You're supposed to flash the experimental OF1 firmware, root with towelroot, and then flash up to the pre-rooted OF3.

Try just starting the entire process from the beginning, and let me know if you need any more help :)

No sorry. I've been experimenting with framework changes in AptOS and never got to it. I'll try to fit it in my schedule towards the end of my week.
[AT&T Samsung Galaxy S 5] triode3:
That is exactly what I am doing. I flash OF1, root, then flash up to pre-rooted OF3. But in your second post, you note that I need to then perform a roll back in order to flash a ROM (in your third post).

OR, am I misreading this, and I can go from pre-rooted OF3 to "Flashing ROMs"?
[AT&T Samsung Galaxy S 5] AptLogic:
The instructions and rollback binaries in post 2 are if you want to go back to unrooted stock or if something goes wrong.

If you're on pre-rooted OF3, then you can go right to flashing ROMs :)
[AT&T Samsung Galaxy S 5] triode3:
OK, this should be my final question (we hope), If I followed post 1 and I am on stock_rooted_from_noship, then I can go to post 3, BUT, do I need to then do Mandatory step 1 (go back to good ol 5)?

Thanks.
[AT&T Samsung Galaxy S 5] AptLogic:
If you're already on the pre-rooted OF3 (which you are), then you can skip step one.
[AT&T Samsung Galaxy S 5] triode3:
Cool deal, did it anyway, but hey, I am further along than before.

Thanks for all the help. This is great work and information for us with the "old" S5!

Thank you again.
[AT&T Samsung Galaxy S 5] SnakeFist:
I just bought this phone unlocked. If i do these steps will my phone still be unlocked? Cause i'm using this phone on the cricket network. My phone already has MM will i still have to downgrade then upgrade to MM for root? And is root permanent or temporary? If i can find it if one was made a CM version be installed? Has the boot loader been unlocked yet for a custom recovery for nandroid backups.
[AT&T Samsung Galaxy S 5] TheMadScientist:
It dont need to be unlocked for cricket. Theyre both att. Lol. Any att phone will accept cricket sims. Even old ass flip phones. So u r good there

And bl is still locked

---------- Post added at 07:18 AM ---------- Previous post was at 07:15 AM ----------

So some how i managed to flash a op rom i think alliance. Now i got a att has detected unauthorized software on my device. And boots to recovery. Ive reread ops a few times nowntrying to figure out what i missed to not end up here again. Can anyone help me out?
[AT&T Samsung Galaxy S 5] Cullub:
The carrier locked/unlocked status should stay the same. Although for using Cricket it shouldn't matter since they use the AT&T network anyway.

Yes, you'll have to downgrade to Lollypop for root, however you won't be able to upgrade back to Marshmallow afterwords. Root is permanent.

As of right now, the bootloader hasn't been unlocked yet. So no custom recoveries and no LineageOS yet.
[AT&T Samsung Galaxy S 5] inspired55:
If it keeps returning to recovery it's because the kernel isn't compatible. You have to remove the IMG file from the rom before flashing.
[AT&T Samsung Galaxy S 5] taadow1030:
If the issue is related to an incompatible kernel you can flash the correct kernel in the AP slot via Odin.
[AT&T Samsung Galaxy S 5] TheMadScientist:
I downloaded a bunch of firmwares last night but havent found individiual kernels yet. Just got off work so ill be looking here in a little while. Its just a play device so no big rush.

[MENTION=7597286]AptLogic[/MENTION] I found this presentation about the bootloader exploit.

https://www.sstic.org/2017/presentation/attacking_samsung_secure_boot/
[AT&T Samsung Galaxy S 5] SnakeFist:
Yes it does. I chatted with at&t and they said even though at&t is the parent company of cricket, cricket is treated as it's own carrier and at&t phones will not work on cricket and cricket phones will not work on at&t unless the phone is unlocked.

Here is an excerpt from the chat with AT&T i had with them asking them about my unlocked phone. So you know for later reference.

AT&T: Hello! How may I help you today?

Juan: Mike, thank you for visiting AT&T! My name is Juan, and I would be happy to assist you with our wireless services and products.

Juan: How can I help you today?

Mike: I want to check if my att phone is unlocked

Juan: The only way to check that is to try to insert the sim of another carrier, if it works, then it means it is unlocked

Juan: Are you able to do that

Mike: I was able to sign up with cricket but i don't think that will work since at&t owns cricket.

Juan: But technically it's another carrier, so it should actually be unlocked Mike.

Juan: Because if you try using locked AT&T phones, on Cricket, it will not work, even though AT&T owns Cricket

Juan: They are still different carriers

Juan: AT&T is just the parent company

But i thought i read that the OP told someone that they even have MM rooted.

Page 179 post #1781 is the reason i asked about MM being able to root.
[AT&T Samsung Galaxy S 5] TheMadScientist:
I can assure you juan is wrong go get any att phone and put a cricket sim in it u dont even have to set apns on g3 g4 s4 s5 all varients s6 and s7s any varient i am a cricket customer and i do this for a pretty good living buying and selling phones. I have on my possesion a att s5 that i used on cricket for a year locked tight. Also u can use straight talk net 10 tracphone att branded sims in locked att phones. If u want to payto unlock it go for it. But trust me

The other issue find the of3 firmware with the multi .tars. And flash the 0f3 kernell i was having that issue also. Also running alliance

[AT&T Samsung Galaxy S 5] GetSet:
What AptLogic meant is that the root method works if you

START

with any software version including the latest 6.0.1. What you wind up with in the end cannot be 6, because MM isn't rootable on the S5. In the end it cannot be anything other than 5 (OF3), or some custom ROM that resembles OF3 to the bootloader, since it remains locked at this time.

I was on vacation, I'll reply to your emails ASAP.

Which ROM version are you interested in ?
[AT&T Samsung Galaxy S 5] Cullub:
Are you Frederic? We basically want to be able to install TWRP so that we can use custom ROMs and stuff. We need the (too large) image that overwrites stuff Samsung didn't intend to make that possible. Also, some step-by-step instructions will have to come at some point...
[AT&T Samsung Galaxy S 5] SnakeFist:
Then why wouldn't my wife's straight talk sim work in my att s5? It came up saying it was network locked. She couldn't use my s5 with her sim to make calls cause it would give the network locked error. So no you are not correct at all. I didn't pay to unlock it i bought it pre-unlocked for the same price as a full price s5. So no i didn't pay extra for nothing.
[AT&T Samsung Galaxy S 5] TheMadScientist:
It wasnt a att branded sim from straight talk then. Im not gonna argue. I use my att s5.on cricket never unlocked everyday. If it was bought unlocked then y. Is it saying network locked.?

Man ive been in this game a long time look over and att samsung threads. Lg any of them. Again u wearnt using a att branded straighttalk sim. If u ise tmobile branded or verizons lte or sprints lte sim its gonna be netwprk locked on a att locked device.

Hi! The question is (if you can answer it) :

Can you put everyone who has a G900-A (and should have gotten a G900-T, including myself) out of their dream state or misery by telling us if you have the steps and files to UNlock the BL of the ONLY SM-G900 in the whole wide world that still has a LOCKED BL after over 3 years???

I do not know how to put it any other way (no offense, I am just a "to the point" kind of person),

THANKS
[AT&T Samsung Galaxy S 5] zeewox:
No, I don't know how to unlock this bootloader, I haven't studied how it works.

I only have a PoC to run custom kernel/recovery.

I'll try to release it soon. But all technical details are already available in the paper.
[AT&T Samsung Galaxy S 5] BrianSamsungTab:
That doesn't matter. Booting to a custom recovery is good enough and will still give a larger level of control than we have now.
[AT&T Samsung Galaxy S 5] taadow1030:
We would be very grateful even for a custom recovery. Having to start at square one via Odin every time we get into a bootloop is something we would like to avoid as much as possible.
[AT&T Samsung Galaxy S 5] samccfl99:
I do not really understand that. This phone can only be on LP or MM (no one wants KK permanently), so if you like a rooted phone, then it will be on LP 5.0.x and stay that way. There should be no bootloop problems or bootloop problems changing roms with FlashFire as long as it is a 5.0 rom.

We need an UNlocked BL to install Real TWRP. SafeStrap was the TWRP for the G900A (and others) before FF came along.

I have an original G900A which I got in 06/2014 and rooted under KK in 10/2014 and has stayed rooted. When I read this thread to begin with way back when, it mutated into about going to MM and then being able to get back to rooted LP and was curious. I was one of the lucky ones to be able to get back before the old method closed up. Of course now there is a permanent way to root and get back to rooted 5.0 thanks to the finding of certain files by some people in here and of course the OP Dev/Documenter. I have never had to try to root again since I got my root back, but am stuck with this OF3 BL and Kernel, of which I used to be on the OA1 BL and OC4 kernel. Still using my beloved modified/bastardized TMS5 3.0, which does load under OF3.

I had a few strange problems a few weeks ago. I had to reboot the phone 3 times in 2 weeks. Twice the screen just would not come back on with any button. The other, the WIFI and 4G went away or was weird. All times I was able to reboot with the hardware buttons. It has not happened lately. Who knows. It's probably tired...LOL (let's see a rotten apple last this long!). I only bring this up because I wanted to dirty flash the rom, but need to do it in SS (supposedly FF has (or had) some security bits problems) and still I could never get a definitive answer, if after running NCE Flasher (flashes OA1 kernel), that the phone will boot into SS with that OF3 BL. Of course if it bootlooped, then I should be able to ODIN the OF3 kernel and reboot normally. I do not want to find out that I cannot get my phone back, even though I have read many people say that it does work. I have no doubt that it does and I know my phone inside and out and can restore what was on it...BUT....LOL.

I know this thread has helped the poor people who got the phone with LP on it already, whether it came new or from some person who took A LP update, and finally got a rooted phone. Happy for you all.

So that is my story. I wish I had money for a G950-F (S8 Intl - Best price NEW now on Ebay $635) :D:laugh:
[AT&T Samsung Galaxy S 5] taadow1030:
Every now and, whether it's because of Xposed incompatibility or a bad build prop edit, a bootloop results. It's so tedious having to start at the beginning if/when this happens. That's why I would even be happy with a TWRP recovery. Plus, I would be more adventurous in trying some of the other (relatively few) 5.0 ROMs that we have access to.
