Also dont worry about the carrier unlock...unless its from CANADA...promise on my life 900T is plug and play....any GSM TMOBILE SIM....tracfone family mobile net 10 straighttalk tmobile prepaid tmobile regular....that phone is so old unless its blacklisted they will hook it up...and best way to go is tracphone by a sim kit hook it up in a gsm unlocked phone then slid it in the S5 my phone is a motorola g7plus i take the sim out and put it in any of my s5 and it works no issue
[AT&T Samsung Galaxy S 5] Delgoth:
The gms.persistent package/services come in through the updated versions of Chrome, Google, Home, etc now though too. So even on the older devices, the services still come into play with the Google Api and Stock FW. So no hiding there either....

But just connecting to any device at all is itself then a unique ID. And if an exploited, or partched/custom FW was in control of the BLE beacon, wouldn't that enable something like a BotNet to construct itself if a zero day or two drops?

On older devices like LP and KK I feel like the permission granting process leaves a lot of rom for something like Janus to spoof the system. A compromised devices with access to a root executable shell would be able to gather information from behind enemy lines at that point if a local network or physical access was present. Just a hypothetical scenario for an injection method.

Given the right social encounter or test lab experiment that API could be used the wrong way with social engineering campaigns like we see with telemarketing....

But you're correct, it has helped, hence the potential for both sides increase. Also think about the msm8974 emmc programmer. Really I need to reorganize my notes and get excel up again to look at the memory registers again. We could potentially remap the 32-bit address space in a worksheet range and then create the partition table for the G900V and attempt an EDL method for Roots/Bootloaders...or patch the trustzone TEE with DC or something because of the old kernel and hardware.

These kinds of things exist for the other models of the S5 yeah, they could for the G900V as well if we can just map out the nand and then write a script to run per device to gather their specific device IDs for the mapper. In theory it should work, like it did for the Exynos7420. Same way.
[AT&T Samsung Galaxy S 5] bryan_mmx:
good day

forgive me, this is off topic, I looted a G900A in my cousin's house. It that has seen better days and I would like to revive it starting with the frame replacement. I was able to find a seller of legit G900F and G900H frame but not sure if there is difference with G900A. seller never encountered G900A so he doesn't know if it is compatible. Anybody confirm for me? I tried looking around the web and this forum but no luck. I did create a topic on this but since this model isn't exactly new, traffic is kinda slow and I'm hoping I could get answers here.
[AT&T Samsung Galaxy S 5] alansworld2010@gmail:
yes its the same only differences that matter are most devices have 2 modem/wifi coaxl wires.... 900a has one....also the daughter board with usb port touch key lights is device specific because of the radio for phone and wifi... and if you can get a 900t motherboard you would be in the best shape...the 900a is stranded at marshmellow 6.0.1 because of the locked bootloader
[AT&T Samsung Galaxy S 5] dave678:
What about an F model?
[AT&T Samsung Galaxy S 5] alansworld2010@gmail:
I'm not sure Exynos would even make it through the first paragraph on Odin as it verify files....this thread is talking about US carrier varrient SM -781u and us unlocked Samsung branded SM-781U1....only Qualcomm snapdragon....
[AT&T Samsung Galaxy S 5] dave678:
G900F is a Snapdragon model
[AT&T Samsung Galaxy S 5] alansworld2010@gmail:
Sorry I just noticed my previous reply and I don't know how I got confused with another thread on a different device...and yes 900f is snapdragon and all the parts of g900a t p v r4 f w8 are interchangeable except the daughter board which needs to match the model of the mother board... I have a 900v originally with a screen pulled from a 900p and I changed both boards out to make it a 900t...the 900f has a different LCD
[AT&T Samsung Galaxy S 5] dave678:
So you also converted the stock software to the tmobile firmware?
[AT&T Samsung Galaxy S 5] alansworld2010@gmail:
The firmware matches the board model right Dave...I thought we were talking about hardware....I starting to feel like you're screwing with me or your US government looking for hackers or the CCP or Samsung so which one is it... I'm so reluctant to post on XDA ever since they changed the app for no good reason it's full of Trolls bots and GOVERNMENT
[AT&T Samsung Galaxy S 5] dave678:
Yes I'm just curious. Because i currently own 2 S5's. G900V and G900T.
[AT&T Samsung Galaxy S 5] robix761:
Hi everybody.

I own a S5 G900A, AT&T, unlocked for italian sim card, MM6.0.1, BB DQD1, security patch April 2017 (!).

Until today I thought it was impossible to root it... Do you confirm it would be possible, instead? Would it be worthy? What Android versione could I put on it?

I ask because I own also a S4, rooted and with Lineage Os 18 installed, that works very very well. And fast..

It's a pity to own a S5 and still have it locked..

Thanks for the answers.
[AT&T Samsung Galaxy S 5] dcarvil:
AFAIK, this is the only way to root a G900A. https://xdaforums.com/t/guide-root-roms-and-other-cool-stuff.3516196/

The bootloader is still locked, so you cannot install a newer/different ROM. In my opinion, it is not worth the effort.
[AT&T Samsung Galaxy S 5] Delgoth:
With a security patch of 2017, as well as MM 6.0.1, I still don't see why an Application wouldn't be able to exploit and attain Root permissions, even with a locked bootloader. Because with access to Safestrap recovery on the MM now, the locked bootloader isn't as much of an issue.

Sadly I don't an application like this built, but with a bit of Researching I bet you we can find a targeted chain of exploits that would give just the window needed to root. Just might not be able to use SuperSu at the end of the day.

Just remember we'd basically need a "System" root, not system-less. And maybe some cache usage.
[AT&T Samsung Galaxy S 5] Rootmaster906:
You can still root it
[AT&T Samsung Galaxy S 5] dkwemn:
Just my luck to get one of the two with an impenetrable bootloader! But with my Alliance ROM no longer updatable, running out of room on my SD that the extra storage card can't use, some key google apps no longer compatible including the lack of a even a Volte HD Voice ROM option for KitKat below 4.44 for the 900a, it's now more a beaten dead horse issue than ever.
[AT&T Samsung Galaxy S 5] dkwemn:
I used the G900A rooted with the Alliance ROM until this year, but based on your intention to use Volte I don't understand why you wanted root on this particular phone in the first place, because rooting it would make it obsolete with the ATT boot loader remaining locked & your having to downgrade to 5.0 Lollipop, of which there is no option for Volte in the settings; this is why I had to upgrade to an unlocked Galaxy S9+ in time for the recent 5G change, even my Alliance ROM was beyond updating!

As to going "back to the future" I never had to try it myself, but if the phone you got on ebay was updated to Android 10, it may be trickier than usual, please research VERY carefully 1st, & if you're still stumped, go on Telegram 2nd to seek advice, you may have to pay someone there to help, but a few more dollars investment is better than a recent purchase of a phone you can't use.
[AT&T Samsung Galaxy S 5] Namenottaken:
This phone started out on 5.0. I was assuming I could upgrade past this somehow by rooting since I could not upgrade officially anyway.
[AT&T Samsung Galaxy S 5] dkwemn:
No, you cannot go past 5.0. on the 900A rooted, it's as far as it can go, despite what you may read elsewhere in, or most particularly outside of this forum; I've read you can go up to Marshmallow un-rooted but do not know how myself, I'm sorry.
[AT&T Samsung Galaxy S 5] Namenottaken:
Would a tutorial for a T-Mobile phone work for ATT?

It all works!

Guys, I have some great news. Both wifi calling AND VoLTE now work on my SM-G900A on the T-mobile network. Here is what I did:

I installed the latest ATT firmware (OA1), released earlier this February. OTA update did not work, so I had to flash the original firmware (ANCE) via Odin, and then flash the two subsequent updates using update.zip on the SD Card. This will remove safestrap and root, but fear not.

Once my phone had AO1 installed, I used this tutorial to root the phone again. It involves temporarily flashing an earlier (ND3) kernel, using TowelRoot, and then reflashing the OA1 kernel

With my OA1 rooted, I installed safestrap. Make sure you install busybox first.

With safestrap, I installed the T-mobile Alliance Rom (build B4).

Seconds after booting, both Wifi Calling and Voice over LTE work!

Enjoy!

Guillaume
[AT&T Samsung Galaxy S 5] Namenottaken:
Sorry about that, here's the proper quote. Wondering if something like this could work on ATT version?
[AT&T Samsung Galaxy S 5] SofaSpud:
I have one of these (S900A) which I rooted. It had Android 5.0 when I bought it, which can be rooted. AFAICT, it has VoLTE capability. It's running ROM build G900AUCU4BOF3. Settings / More Networks / Mobile Networks / Mobile data / Enhanced 4G LTE services is enabled which has the description "Turn on HD Voice and enhanced communications over the network. You can install this ROM after downloading it to get your VoLTE. Are you sure that the option is not shown in the settings menu of your 4.4.2 ROM? I set it up over a year ago, so don't remember all the details, such as whether I had to roll back to a 4.4.2 ROM in order to root it.
[AT&T Samsung Galaxy S 5] SofaSpud:
Unless I'm mistaken, my rooted 900A on BOF3 (Lollipop) is set for VoLTE.
[AT&T Samsung Galaxy S 5] Namenottaken:
I'm a bit of a noob when it comes to this so that is why i'm asking for complete clarification on the rooting guide that I was using. I am unsure how to proceed and do not want to screw up my phone.
[AT&T Samsung Galaxy S 5] Namenottaken:
I didn't see it. My phone is in a weird state right now so I am unsure how to proceed.
[AT&T Samsung Galaxy S 5] SofaSpud:
Settings / More Networks / Mobile Networks / Mobile data / Enhanced 4G LTE services is enabled which has the description "Turn on HD Voice and enhanced communications over the network."

*#*#4636#*#* brings up device status screen: "Network Type: LTE"

With a '4G' symbol beside the signal strength indicator too (S5 & S7). S7 is rooted MM 6.0.1. Bandwidth speedtest is very close to the same on both. Provider is AT&T, (prepaid).
[AT&T Samsung Galaxy S 5] SofaSpud:
You can usually get back to a known, sane state by booting into fastboot mode, then flashing back to the last known working ROM. Be careful about just jumping between ROM levels, rather than going in sequence. Sometimes it can be confusing to figure out the bast pathway to take due to the info being scattered around between so many different threads.
[AT&T Samsung Galaxy S 5] Namenottaken:
Can you get away with going from 4.4.2 to say a pre rooted 5 or do I need to go to 4.4.4 first?
[AT&T Samsung Galaxy S 5] Namenottaken:
There was also a method of making sure your 900A was on official 4.4.4 and then upgrading to rooted 5.0 by using a method that I was attempting to use previously. I think that this tutorial I was using just left out some steps that the tutorial I found goes a bit more into. Would I run into issues just going to official 4.4.4 and continuing from there?
[AT&T Samsung Galaxy S 5] SofaSpud:
I think you'd be OK there. Main thing is not to skip from KK to MM, AFAIK. I'm not an expert with these devices, but I have managed to root a number of devices. One of the concerns about going too far ahead with ROM versions seems to be that (I believe) they can also carry a security update, which can make the device unrootable. Just something to think about.
[AT&T Samsung Galaxy S 5] Namenottaken:
I was able to figure out how to properly follow the original guide (with the additional info) and I am now on a rooted version of 5.0 with Volte. Everything is working and good to go. Thanks. :)

Hi. That🔝ROM from that🔝post; it works on G900A AT&T?. Im currently on Alliance ROM Lollipop 5.0 with SafeStrap TWRP. I want a ROM for gaming Free Fire without lag and seems that that one is the best, so, wanna give it a try. The ROM dev doesnt answer :/ Will it work? Saludos!

I Applied this exploit to boot TWRP/AOSP ROM's on G900A. The guide I made is here. Hopefully it helps someone :)
[AT&T Samsung Galaxy S 5] A Cool User:
No... The G900A does not have a unlocked bootloader. If you use the Temporary Unlock exploit then yes.
[AT&T Samsung Galaxy S 5] renatortb:
I'm a newbie, but i realised that:

1. When a flash a rom for other carrier or other unofficial i have to replace the kernel via Odin for obvious reasons ("SECURE FAIL: KERNEL" = usually the kernel of others roms does not have support for G900A). So i put my phone in the download mode (hold power+home+vol.down buttons) and falsh the OC4 kernel via AP in Odin.

2. In most of unofficial roms i tested, i have to install manually the Google Play services 10.0.84 and Google Play Store 7.3.07.K-all [0] [PR] 139935798. I like to install also [root] FlashFire 0.53 and SuperSU 2.79. Remember that you have to go in the phone settings in "Security" and enable "Unknow Sources".

3. After all that i usually get the rom running good.

4. I'm liking ver much the PhoeniX v11 rom.

5. Take a look in this post.
[AT&T Samsung Galaxy S 5] UsandThem:
I also flashed PhoeniX ROM v11 and I'm really liking it. I'm going through this whole list, BTW. [MENTION=7597286]AptLogic[/MENTION] wanna let others know?

Yeah ill edit it tomorrow.. Too late for tonight lmao

Update: appropriate post has been updated.
[AT&T Samsung Galaxy S 5] IJoxer:
Hey, I created that thread, glad to see it finally being put to use. I think my personal favorite from testing was the Xtrestolite 2.2 rom, it's literally barebones though, so you'll need to transfer a file manager and google play services/store to get started setting it up.

Now, being on g870a, I'm desperately trying to find a way to downgrade so I can root up and flash it, the battery life and speed was leaps and bounds above MM on its best day, I really wish I hadn't upgraded.

Anyways, give Xtrestrolite a shot if you really want a quick and minimal experience, otherwise I'd stick with Alliance or S5 Lollipop by Ambasadii was quite nice too, for a little known rom.
[AT&T Samsung Galaxy S 5] 719c6:
Yup.
[AT&T Samsung Galaxy S 5] UsandThem:
You upgraded via OTA? What Android version are you running? I'm not sure if you can downgrade from taking an OTA. Correct me anyone if I'm wrong.
[AT&T Samsung Galaxy S 5] AptLogic:
If the baseband you are on starts with G870AUCU4 or G870AUCS4, you can downgrade to any build with a baseband that starts with that
[AT&T Samsung Galaxy S 5] IJoxer:
I didn't use actual ota, but I used the 870 update files found here on XDA, I'm currently on PH2.

---------- Post added at 10:25 PM ---------- Previous post was at 10:18 PM ----------

My baseband is G870AUCU2DPH2, so I should theoretically be able to get it back down to G870AUCU2BOF3?

I hope so, because that is precisely what I need for root, and I'll be a happy camper!
[AT&T Samsung Galaxy S 5] AptLogic:
Yeah you should be able to. That 2 in G870AUCU2 tells you what bootloader increment you're on. So you can flash another 2 but not a 1
[AT&T Samsung Galaxy S 5] IJoxer:
So, I'm set, just need to find a way to flash with Odin, since we need root for flashfire. I'm starting to get excited, thanks for the help!
[AT&T Samsung Galaxy S 5] AptLogic:
Happy to help!
[AT&T Samsung Galaxy S 5] 719c6:
I'm on G870AUCS2DPH4 -- so what can I flash back down to? ???
[AT&T Samsung Galaxy S 5] IJoxer:
Same as me, you can flash back down to OF3, where we can obtain root, but now we need odin flashable files, since we don't have root to use FF. [MENTION=7597286]AptLogic[/MENTION] says he may be able to reverse engineer something for us, but no promises.

EDIT

Actually, if his methods apply to us, which they should, once we're on OF3, we should be able to upgrade to PB2 and still root, not that it'd be much of a difference, but it seems like it should be possible, possibly even as high as PB6.
[AT&T Samsung Galaxy S 5] 719c6:
I can't find a tarball set anywhere for the G870A... wth. :(
[AT&T Samsung Galaxy S 5] IJoxer:
Same, thats why AptLogic was going to try to make one, the way I remember people making them didn't seem possible using the OJ3 rom, I'm going to take a look at the OF3 rom to see if it's any different. Hopefully, AL can get something thrown together for us, then we should all be able to be on the same page as far as root goes! :D
[AT&T Samsung Galaxy S 5] AptLogic:
Yeah ill be working on it through tomorrow. I've got a thing to go to tonight so I'm out of action for the day. Shouldn't take all too long I think...
[AT&T Samsung Galaxy S 5] IJoxer:
I'm looking into it right now, I'm no genius, but I'm sure I can figure it out if I can find some applicable information. If you have a second, could you maybe throw me a rough tut about how you'd do it, if not I understand. I just hopped on my Arch build, I think linux is necessary to tar the files we need properly.

Either way, thanks and have a great night!
[AT&T Samsung Galaxy S 5] Helgen:
I've been using the alliance rom, and man, it gives me so many problems. Many

Unfortunately, Google Play Services Has Stopped" messages whenever I do something involving social media, the fonts never match the menus often, after hours of messing with options and there's no "go back to defaut" setting. I'd say stay away from this rom.
[AT&T Samsung Galaxy S 5] IJoxer:
Did you try a factory reset from recovery? I don't see why it'd give you issues, but I was never a fan of Alliance myself, did seem a bit slow compared to others I've used.
