You need to use SuperSume to get SuperSU. You can get it from the Play Store for $3.99 (I think), or you can look for an APK on xda somewhere. You need to make sure you have Kingroot 4.81 or it will reject SuperSume and it won't run.

Can we get Safestrap working?
[AT&T Samsung Galaxy S 5] AptLogic:
I was just testing that. I managed to get Safestrap to work by just installing busybox and then safestrap. Unfortunately I bricked my device soon after trying to install Phoenix ROM and I'm waiting for it to restart XD (Update: Debricked successfully, PM me if you need the OI5 restore files ;) )

If I do find a way to install a ROM, the instructions (as well as a list of compatible ROMs) will be put into Reply #3 in this thread.

If we could get one of those Nougat ROMs to work that would be AMAZING.
[AT&T Samsung Galaxy S 5] LuckyNumberHat:
I stopped updating OF3 back when [MENTION=4708661]muniz_ri[/MENTION] was the one leading the charge. Is there a preferred method to OI5 (or PA2?) that will allow for trying out this root method while preserving the ability to get back to rooted OF3?
[AT&T Samsung Galaxy S 5] AptLogic:
No, sorry. But if you're already rooted on OF3 you may as well just stay on it until we can figure out ROMing on phones with newer basebands.
[AT&T Samsung Galaxy S 5] AptLogic:
Okay SO after THREE bricks (count em), I have come to the conclusion that ROMing this phone on Lollipop with Safestrap is NOT POSSIBLE.

At this point I'm going to invite [MENTION=631273]Chainfire[/MENTION] to the party, maybe he can give us a helping hand. There is a possibility that we can use Flashfire. I'll probably try that next. I plan to be up pretty late working on this.

If anyone else wants to share input please do. Right now I'm trying to flash the Resurrection Remix 7.1 ROM.
[AT&T Samsung Galaxy S 5] lingo2012:
Yeah i tried with flashfire but it just sat at the Galaxy S5 screen.
[AT&T Samsung Galaxy S 5] brezulja:
Is there any chance of bricking the phone if i try to root CPA4?
[AT&T Samsung Galaxy S 5] Mavy1000:
Can anyone help me with this? I am currently on CPA2 and I can run kingroot 5.0 and then uninstall it to run 4.8 and re root which works fine. Then I run Super-Sume and that works fine too it installs SuperSU but then SuperSU asks me to update which I do and it reboots after a successful attempt and I am no longer rooted. Has anyone had this issue?
[AT&T Samsung Galaxy S 5] jundzz:
I am from Brazil, and I was with the OF3 lollipop 5.0 firmware.. I follow the steps (except the downgrade) and got really really happy when succeeded the root and even more happy when

succeeded the flashing. I flashed the Aliance Rom, and I cannot access the playstore either.. got the same message... "service has stopped"..

If someone can help, I would appreciate..

I was thinking in trying the cm13 or cm14 instead.. Any thoughts?? Thank you..
[AT&T Samsung Galaxy S 5] AptLogic:
Oh darn... I'm sorry I'm not at my desktop which has the file ):

I hope it'll be up soon
[AT&T Samsung Galaxy S 5] jundzz:
Resolved.. just download last google play service and it´s working.. Thank you anyway.. :D:D:D
[AT&T Samsung Galaxy S 5] Helgen:
Thanks for the consideration, but I couldn't possibly ask you to upload it after all the work you've done. It's working now, I will upload it after this. I always remembered AFH to be inconsistent and slow usually :)
[AT&T Samsung Galaxy S 5] AptLogic:
Oh come on, I'm only getting started here :3

I'm always happy to do whatever I can to help my fellow S5 users. If that means reuploading something, I'll gladly do it.

Its good that AFH is back up. I've been considering making a mirror for it but my Azure free subscription can only let me store so much xD

Also just a general note: I am still looking for testers to help me work on some fun stuff. I've got some ideas but i can't get them up without people to test it first!
[AT&T Samsung Galaxy S 5] Helgen:
No dude, I will upload mirrors in a bit, don't even worry about it, worry about the juicy stuff lol.

As for the testing... I would, but I'm actually doing this on my main phone which probably isn't the best idea, but I f*&^%$# hate TouchWiz so much, but I will report back in when I get back to the OF3 which I'm currently downloading and I am looking toward installing a custom rom, too... Mind telling me what you want to test though? I might be up to it :D PM me if it's in secret. I should probably get to OF3 first of course for the time being.

By the way, I'm uploading mirrors for Odin, OI5 and OF3.
[AT&T Samsung Galaxy S 5] AptLogic:
I'm working on a prerooted MM ROM right now, and after I get that working I'll start delving into some ports from other devices and possibly try to get something that looks a lot more like AOSP working :)

Not much, but its a start
[AT&T Samsung Galaxy S 5] :
Works great for me I followed what SmokeyDog said because I was having the same issue and I'm rooted and running Alliance 8.

I have a question, would it be safe to install xposed with flashfire? I haven't tried it yet could anyone verify that it works without any problems?

Edit: I went ahead and flashed xposed with flashfire and it working fine with no problems.
[AT&T Samsung Galaxy S 5] Helgen:
Alright [MENTION=7597286]AptLogic[/MENTION], I'm sure you'll post the results as soon as you get them :D

As for download mirrors, here they go!

I am stucked at updating the su binary, i cant get super sume to work, it is stucked. :/ how did you manage to get the su binary updated?

EDIT:

Nevermind, got it working, the version os super-sume pro (9.3.8) didnt work, used 6.0.

So my process was, kintroot 4.8.1, then supersume 6.0 then its done, wont reboot phone yet, until i flash 5.0 prerooted as guide says.

Thank you all.
[AT&T Samsung Galaxy S 5] nman729:
Bricked. Unfortunately using kingroot 4.8 my galaxy s5 is now in a forever reboot loop. I would attempt to use Odin, but my phone's charging port is broken. Is there any hope?
[AT&T Samsung Galaxy S 5] AptLogic:
Okay so an update on the MM:

Every time I zip up the ROM and flash it, system fails to mount... I think this is due to the way I pre-rooted it, I'll work on that.

If of course that's not the issue, I'm going to work on an alternate method that uses an OF3-PH4 update binary instead of a ROM zip, we'll see how that works.
[AT&T Samsung Galaxy S 5] Helgen:
How do you expect to do anything with a broken charging port? You'd need to charge your phone to do most of the work man... Refer to this video to replace the logic board. You're not really going to get any further without that port and most likely Odin, as you said. Can you at least get into recovery mode?

After hours of messing with the alliance rom, I feel like I am looking forward to going back to 6.1. V5 Android is a bit dated, I'm missing that material design :D I'm hoping you can get around to 6.1, because I will try it as I didn't set up much purposely for this.
[AT&T Samsung Galaxy S 5] GChundrlek:
I'm subscribed to the thread. I have a stock SM-G900A and a laptop with Windows 7 and Odin. If I can help in any way, just let me know.
[AT&T Samsung Galaxy S 5] Helgen:
Message [MENTION=7597286]AptLogic[/MENTION], he's looking for people to test.
[AT&T Samsung Galaxy S 5] AptLogic:
I'm going to give the zip a couple more modifications and see if it works. Otherwise I'll try to modify an OTA installer and we'll see where that gets us
[AT&T Samsung Galaxy S 5] nman729:
Yeah I kinda figured that. It was kind of a last ditch effort to root. My charging port has been broken for a while,i just charge it with an external charger and have 3 batteries. And yes I can get into recovery. I actually just picked up a Google pixel. Do you think it's worth it to try and fix the port on my s5?
[AT&T Samsung Galaxy S 5] invert_nexus:
A new logic board will cost you. Just replacing the charging port would be more reasonable, but would require microsoldering skills and equipment.
[AT&T Samsung Galaxy S 5] renatortb:
I don't know much, but i can help somehow too. G900A here, laptop with Windows 10 / Linux Mint 18 and a lot of desire to learn more... :):cowboy:
[AT&T Samsung Galaxy S 5] AptLogic:
Alright guys, I think I've fixed the issue I was having where the device wouldn't start after flashing.. I'm just gonna test it on my device first and then release it to my beta testers.

Follow up will be here in around 30 minutes

FOLLOW UP: Once again, the attempt sofbricked my device :/ At this point I have no idea why it keeps rejecting the zip... I'll give it another try, and add some more files this time lol

Another update: I tried a couple more test binaries and have still gotten no luck with rooting the device... next up is forcing a Systemless SU installation. Gonna try that right now and then I'm done for the night.
[AT&T Samsung Galaxy S 5] ZenexURL:
Thanks

Thanks Man! Got everything working for now, if I have anymore problems I'll let you know!

Is there any way to get xposed on the rooted stock rom on the first page?

Could you give me the link to the downgrading exploit?
[AT&T Samsung Galaxy S 5] causticfix:
You'll need to flash a 900a kernel after flashing Phoenix, it was designed for the 900t & wont boot until you flash a proper 900a kernel. I don't have time to find a link right now, but if you can't find it by the time I get off work tonight I can probably post a link.

As far as the exploit, it's literally the very first post in this thread. The experimental firmware, which is the very first link, will allow downgrading from any baseband version.

[AT&T Samsung Galaxy S 5] RebelLion_:
WOW. I can't wait to see how the marshmallow project goes. I have tried a handful of different roms for the g900a and bricked my phone at least double that amount thanks to locked bootloader and a limited custom recovery. X ROM continues to be my top favorite since it's so lightweight, stable, and can support I'm sure every feature available to this device. I will definitely be interested in testing any alpha/beta builds you have. Im going to test the limits of the rom slot in SafeStrap for being able to have a virtual rom along with my stock and use this to try any risky roms and mods. Thank you for the amazing work AptLogic! A million thanks since I am very limited on funds and cannot donate for my gratitude :D:svetius:

From what I read in the most recent posts of the OP thread slot 1 works but it might be buggy. Still trying to figure out how to resize my phones partitions so I can have a slim system1 partition for x rom and the rest for system2 and it's data

[AT&T Samsung Galaxy S 5] AptLogic:
The problem with leaving the baseband as-is, is that Samsung has tightened their restrictions on what will boot in what combination. The marshmallow Kernel won't boot without the Marshmallow aboot, which in turn requires a Marshmallow Trustzone, sbl, rpm, etc...

I have been able to use a Lollipop recovery, but it didn't work too well on Marshmallow.

And another issue with jumping to a version like Nougat is that the kernel doesn't support pure AOSP ROMs, which is the issue I'm currently facing while working on bringing AptOS to Marshmallow. So what I have to do is compile all the libraries and APKs in a build environment, and then diff them against the stock ROM and try to integrate the changes. Doesn't always work but I hope to get somewhere by replacing most of the AOSP binaries with stock, splicing the framework resources together, and then trying each new APK one at a time to see what works and what doesn't.

Root y Recovery

Hi AptLogic! I got 900A 0F2 5.0 stock rom. Will this work on my model and if is there an cwm or twrp already working for this model too? Cause want to backup stock, Nandroid bkup before apply this method. Thanks in advance!
[AT&T Samsung Galaxy S 5] whodisname:
Yo, also if you have have files like safestrap or anything useful, I can post up a link. Not many of those still work.
[AT&T Samsung Galaxy S 5] NavSad:
Well, I believe now that the support cycle of this device is over, and AT&T will no longer support it. This means that we don't have to worry about any more updates that will increment our aboot fuses, preventing us from downgrading.
[AT&T Samsung Galaxy S 5] AptLogic:
Before I get to replying, I apologize for the delay. Google decided not to tell me that I was 101% over my storage quota and apparently I have unknowingly not been receiving emails for about three days. Working on transferring my large files to other storage providers so this doesn't happen again.

Yes this will work on your model and Android version. Unfortunately we don't have CWM or TWRP, the best we have is Safestrap or FlashFire backups but you can only use those after you complete the rooting process.

You might have some luck backing up via ADB (google it), but that's about as far as you can get backup-wise.

Which means this method is confirmed working on ALL ANDROID VERSIONS for this device. One less thing to worry about, now hopefully Samsung will let us unlock the bootloaders with their Upcycling thing (supposed to be coming soon). At this point all we can do is wait and hope for that or a bootloader exploit.

Disable SD Card Error Scanning

A little off-topic I suppose, but since our S5's are now rooted, one of the things we are able to do is to disable the annoying error scanning of the external SD card. Since I am using a 128 Gb micro SD card, every time I insert the card (or even just reboot the phone) I have to wait about 10 minutes for the card to mount and make the files available. Besides that, it eats up battery power. Why is Android obsessive about checking for errors like this? MS Windows never does this kind of exhaustive check when mounting; it just mounts it and lets you use it.

Anyway to disable it, go to /system/bin and rename fsck.exfat as something else, or in some other fashion disable this file. This apparently is File System Check (FSCK) for exfat. Another forum that I got this idea from suggested doing this, but said to disable fsck_msdos instead. This didn't work for me, probably because I have a larger SD card that is formatted exfat.

Android loves to say, "SD card is damaged. Try reformatting it." This is a lie. It has commonly told me this on my S5 using the 128 Gb card, and previously on my S4 using my 64 Gb card. The truth is, the SD card is not damaged and it doesn't need to be reformatted. Reformatting an SD card unnecessarily is harmful, since flash memory isn't designed to be rewritten constantly, because doing so reduces it's life. Taking the same SD card and mounting it on a Windows laptop usually results in it mounting instantly, with no error complaints (even if you deliberately check it for errors). Disabling the fsck.exfat file also prevents these annoying messages about the SD card being damaged.

Modem Crash?

Hi! I've tried going through the procedure but just right after step one, of installing the experimental firmware, instead of rebooting the phone went into a screen that looks like download mode, but that said "Modem Crash".

I was able to recover using the BOF3, but now I have lost SIM card detection completely.

What can I do?
[AT&T Samsung Galaxy S 5] AptLogic:
Go into the device settings > about > status and tell me if the IMEI field is showing your device's IMEI (don't tell me the IMEI, just tell me if it's there)
[AT&T Samsung Galaxy S 5] divergentmobile:
IMEI is null, baseband is unknown ):

I've heard very bad things about this and I'm reading it might even mean they gave me a stolen phone?

I got the S5 from eBay but the seller has 99.9% feedback so I wonder was it just me flashing with odin that did the damage.

Have to say, the phone DID turn on by itself kinda randomly from the very start.

Stupidly I haven't tested the simcard before going with Odin. I think maybe it was already like this.
[AT&T Samsung Galaxy S 5] AptLogic:
Unfortunately a null IMEI means your EFS has either been wiped or corrupted, which explains the modem crash you experienced.

Most of the phone's functions will work, but you will have no way to use the cellular radio, that means no calls, SMS, mobile data, etc.

Usually there would be two ways to fix this:

First would be to restore a backup you made of the efs partiton but you obviously don't have an efs backup so we can't use that approach. In the future, I recommend buying a phone with an unlockable bootloader and backing up efs before you make any further modifications. I backed up my OnePlus 5T's EFS right after I rooted so that I wouldn't have any issues.

The other approach would be to reconstruct the efs partition with the IMEI code listed on the back of the device in the battery compartment. But because we have a locked bootloader, I'm not sure you would get very far.

Your best bet would be to make sure that the phone is on stock and then try and return it to the ebay seller for a refund. If the listing did not specify that there were IMEI or modem issues, eBay will require the seller to accept the return and issue a refund, since its false advertising if they advertised a working phone.

Some Instructions for Returning devices in circumstances like this:

DO NOT tell the seller or ebay that you made any modifications to the device.

DO NOT admit fault for device damage, in this case the corrupted efs

DO make yourself look as tech-illiterate as possible without making the seller suspicious. If the seller believes you don't know how to modify Android devices, they will be more inclined to accept the return, and it will be easier for you to make eBay step in if the seller doesn't comply.

DO factory reset the device, make sure you're running complete stock, fully charge and turn off the device.

DO NOT use the device again after you reset and power off.

Hopefully the seller will accept the return and issue a refund, but if they don't respond to your return requests or if they refuse to issue a refund, do not hesitate to contact eBay, as in this case the seller is already violating the ToS if they didn't disclose the issue before sale. I've dealt with this kind of thing before with some smartwatches that were advertised to be running Android Wear, but were really running some weird Chinese generic ROM, I pointed this out to the seller and they immediately sent me a return shipping label, since they knew that kind of false advertising was a violation of eBay's policies.

If you encounter any additional issues, don't hesitate to contact me directly on Discord (5am-12am EST M-F, 10am-12am EST Sat-Sun): @ The Munsta#3086

By the way, if anyone else is having issues with returning devices like this on eBay, feel free to use these instructions!

Good luck, and maybe you should consider a more dev-friendly device like the OnePlus line if you plan to root/ROM in the future :)

I can't flash the stock, it gives auth (fail).

I'm trying to flash the AUCUANCE stock, I can't get to the name now but I'll post it later.

BOF3 and COI5 both say "custom" when you turn on... how do I get around that? Any other way to go back to stock?
[AT&T Samsung Galaxy S 5] AptLogic:
OF3 or OI5 would work fine in this case, since they are both stock.

As for the "Custom" flag, reboot to recovery, wipe the cache partitions, and then give it a couple reboots for the flags that determine whether or not to display that to be flushed. That should get it off the boot splash.
[AT&T Samsung Galaxy S 5] divergentmobile:
I love you. I'll try that.

I was too slow at doing this tho so it's been more than 30 days since the sale... they do give a 12 month warrantee though so maybe I can get lucky? I'll give it a shot.

Otherwise, can I just spend like 80 euro on a repair shop or something, would they be able to fix it do you think?

It's for my girlfriend and she's been waiting a while.

God I got myself a smg900f and everything was SO EASY ):

The insertion didn't say exactly which model and there were so few on sale, I went with this and took a bet. Darn.
[AT&T Samsung Galaxy S 5] AptLogic:
No, sadly this is one of the things a repair shop cannot fix. The two methods I pointed out to you can usually be done by someone with enough knowledge of android, which based on your experience with the G900F you appear to have.

If a repair place could fix this, so could you (not to mention it would save 80 euros).
[AT&T Samsung Galaxy S 5] MO35AB:
i lost my bootloader :'(

was gonna try to install few stuff to pass safety net check, i ended up with "unsupported content visit nearest at & t shop to fix your phone" or something at the boot-loader screen, help.

is there a way to restore my boot-loader ?

do i have to reflash my S5 ?

is there an easy way to bypass safety net ?
[AT&T Samsung Galaxy S 5] AptLogic:
You'll have to re-flash, and do the root process again.

Uninstalling things won't suddenly make you pass safetynet, as long as the device is rooted, it won't pass.
[AT&T Samsung Galaxy S 5] MO35AB:
i was following this video :

https://www.youtube.com/watch?v=Spx3m0__fM8

to install : safestrap ===> to install magisk ===> to bypass safetynet

is there a way you know of that works ?
[AT&T Samsung Galaxy S 5] AptLogic:
No there is not. Magisk directly modifies the boot image, which results in the device not being able to boot.

If you want to pass safetynet, you have to be unrooted. If you absolutely need both root and a passing safetynet status, I recommend just getting a new phone (my 5T has magisk and passes safetynet with an unlocked bootloader and custom kernel :D )
[AT&T Samsung Galaxy S 5] MO35AB:
wooooow getting dizzy here.

so there is no way to restore my bootloader ?
[AT&T Samsung Galaxy S 5] AptLogic:
Just re-flash either the KitKat firmware (if you want to root again) or the lollipop firmware.
