[Q] AT&T S5 (SM-G900A) Custom Recovery/ROM?

I've been doing a lot of research on installing a custom recovery on my S5 and then a custom ROM. So far every guide I've read said that since AT&T has a locked/encrypted boot loader and that installing a custom recovery should be impossible; however, I seem to have an unlocked phone (unlocked padlock on boot screen). I'm guessing this phones a unicorn, but don't want to brick it by accident either. Is there a way I could check if this is possible without risking bricking the device? I'm sorry if this question is dumb. I've owned 4 HTC phones in the past and as you all know HTC makes installing custom software incredibly easy. Thanks in advance for any advice you can give!
Also I'm a new user so I can't attach images. Here are the URLs though. Sorry for breaking the rules, but it's not spam. I just need some advice

Thanks Rakuu. So what exactly does the padlock mean? I have Lollipop and it's rooted. Coming from HTC phones, I thought it meant I could go ahead and flash something custom.

If you're using your phone as it came to you out of the box, it's not rooted and if it's running 5.0/5.1 lollipop, then, thanks to AT&T's encryption methods, rooting will be near on impossible.....

I'm running 5.0 and have root. I'm just trying to figure out if I can install a custom ROM, lets say Cyanogenmod. Everything I read says I can't, but apparently that's due to AT&T's locked boot loader and it appears mine is unlocked. I guess, I'm just trying to figure out what the hurdle is.

Its not unlocked, ignore the padlock its just cause you're rooted. You can only install touchwiz based roms, check the att s5 section, there's 3 or 4 different ones you can try.

Hi, let's see if you can respond from here, I could Flash an equal phone by following your guide here: https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres- t3516196
I already managed to be ROOT with SuperUser, the problem is that I now need Custom Recovery for this terminal, I do not know if the TWRP For S5 klte (Flash to Odin) or the Philz Touch 6.26.6 Klte fgor S5 SM-G900A. The issue is that your guide (in that thread) installs everything by FlashFire, as I do now to install in this new ROM (ROM Firmware SM-G900A_OF3_Stock_Rooted_By noship) the Custom Recovery? I think I need it to install the Patch to enable Tethering native WiFi on AT & T on Samsung Galaxy S5 T-Mobile.
This phone does not have WiFi enabled.

Help On My Rooted Samsung S5 SM900V Verizon Phone

I have a Rooted sm900v Verizon phone.Im on 5.0 with Knox,detoxed.So its been few yrs now and was wondering what latest OS i can run with KNox ,detoxed,or should i stay on 5.0,if so can you point out to whats out there for my version?I remember when i rooted my phone i had to pick a certain root then.So with that said just seeing if i can run a better/upgrade OS these days like OREO as an example.Looking for some feedback what other Samsung S5 sm900v guys are running,thanks.

I was on 6.0 and went to 5.0, then rooted it, unblocked the bootloader, flashed lineage.

Yo, I see you are a man of culture as well. My S5 is currently running LineageOS 15.1 (Official!) and it is BEAUTIFUL. Runs like a dream. If you want, I can show you how to get the bootloader unlocked and flash TWRP. Send me a PM if you're interested! Best of luck on your journey bro.

Jiwan, would you mind sharing the procedures here or a link to them? I have the SM-903VL model, and while I understand it's a different device, it may not be so dissimilar. I have been attempting root and twrp flash for a while and it seems 2 things are at issue, 1. I had no clue what I was doing when I started, and now, while I have some knowledge, I realize just how much I am going to have to learn If I want to figure out a root method.
2. This SM-903VL is locked up tighter than a nuns corset.
Your knowledge on the afore mentioned procedure would help me understand the workings of these phones a bit better, and, on an off chance, might actually do the trick of at least getting twrp installed.
I have the stock recovery file to insert into the TWRP.

If I could revive and piggyback on this discussion - I'd like the help you offered with getting my g900v re-rooted with TWRP running. I had a nandroid backup and accidently deleted the TWRP, which forced me to re-stock and re-root. I have not been able to recover with safestrap (not impressed) also, I kept getting gapps failures once up and running (Lollipop 5.0 rooted). My initial goal was to flash resurrection or lineage and now I am finding that most instructions say the G900v is not unlockable and I feel stuck. Would you mind sharing with me what your method was or point me to a link that you followed? - I think my chipset started with 11 (as opposed to 15) if I'm using the proper terminology.

TWRP Tutorial? Custom ROMs/GSIs?

Anyone installed TWRP and willing to write a little tutorial? I'm already bootloader unlocked and rooted, but a bad xposed module caused a factory reset. So I figure now's the time. Also, I've heard TWRP only works on Oreo, is it possible to downgrade by flashing the Oreo .kdz? I've seen that both Pie and Oreo have the same AntiRollBack version, but I'd like to confirm with anyone who's actually done it. Also, are there any custom ROMs or working GSIs? I feel bad for asking but it seems like these forums have almost totally died and there is definitely information out there that doesn't get posted here.

How did you unlock the bootloader?

Paid someone with an Octoplus box to unlock it remotely.

Can I please get the info

Can't find XAA or ATT binary 7 firmware. Please help

I have an AT&T Galaxy G950u with my most recent firmware being g950usqs7dtb1. I flashed a combination file (g950usqu7ask1) to turn on OEM unlock so I could install Havoc (I know now, I didn't have to do all that,) but now I can't get Odin to flash any stock ROMs back to install TWRP. The main error I'm receiving in Odin is FAIL! (Auth).
I've tried all kinds of ROMs but I can't find my original ROM anywhere except some shady site that definitely isn't legit.
When I boot into Download/Odin mode the numbers next to RP SWREV are B7(2.1.1.1.1) k6 S7
The error on my phone is SW Rev Check fail: (ab)) Fused 7 > Binary 1
I realized I probably need a carrier free (XAA) or ATT firmware that is binary 7. The problem is it's so recent I can't find any binary 7 firmwares out there. I've searched Updato and couldn't find xaa firmware for binary 7
Working with patched/modded Odin 3B v3.14.1
If anyone can help I would be so grateful.
Edit: I've tried Frija and it says ATT not supported, and it says it can't find anything for XAA. I've also searched Updato thoroughly and can't find a binary 7 file.
Edit 2: I found a ROM.

Well first off you can't flash any custom ROMs on this device it has a locked bootloader. Oem unlock doesn't matter. It's useless. Garbage. That's all for that. Flash any other carrier firmware and flash the oyn csc not home. It will repersonalize for att as the firmware are actually multi carrier. Att included.

Thanks for the input. I'm trying to flash twrp as a custom recovery but it gets stuck on "waiting for device". I've updated all drivers and have no error in device manager

Hey there @TheMadScientist not following you! haha. Just came across this thread as im researching what elliwigy and jrkruse have done.
To @uberdad search for anything s8 SM-G950 by jrkruse and elliwigy here and you should have a solution if your device is still on 7. Wont be twrp but will be safestrap twrp. You can install a custom rom then.

There are no custom roms. You can only have root on a 7.0 stock system img. Please research more before beginning to pass on information. As well this thread is now old no need to dig up old stuff. I helped out with some of the stuff on this device I know what it can and cannot do. Here wanted to install a los based rom. which is a big no. Add I said to begin with

Then he was trying to flash twrp. Which is a big no. Please don't go dragging up a bunch of old threads we have dealt with. This leads to confusing people

Hi. Yes you are right I should have said Slightly Cooked Rom or Modified System Image. However preferred to put Custom Rom due to the fact the amount of new Customization Enthusiasts here on XDA to make it simpler. Also sure yes USER Root on XDA only obtained on 7.0 (at least public). Little off topic but our team has a *working* root along with our own SuperUser which means for repairs pretty much but if time was put into it could become possibly a semi to full user root. I have used Magisk SU older versions along with our root and had a semi working user root on past Galaxies.. Anyhow we don't really have time, especially myself, to work on an actual user root for every device i/we work on.
In the world of forums threads never really grow old they just go into a deep sleep eventually....Until someone wakes it up with the thirst for knowledge. It's how the internet works when it comes to these here BBS/Forums/Blogs etc. =]
What he asked could be something someone else might ask or attempt trying (he shouldnt have even got as far as he did unless on international variant which makes the Q odd.. haha eh? however i felt the need to straighten it up for anyone who might read and get confused. See what im saying..? along with the previous statement about data no become stale.
The more ya know the smarter you become. Information makes the world go around. .. IMO Always best to keep it flowing constantly added to.

Firmware change on S7 edge.

Hello everyone. I'm new here. I wanted to know if I can change my S7 edge (exynos) sm-g935fd firmware from UAE to India. I am currently on Oreo G935FXXS8ETCA Xsg which has bootloader 8 if I'm not wrong, but I want to install ins firmware G935FODD7ETA1 also Oreo which has bootloader 7 . Is this switch possible?
P.s. I want to change firmware bcoz I am not getting volte on my phone. I've tried a few things without any luck. And the only solution seems to be to change my CSC. Any help will be appreciated.

As far as I know you can't downgrade due to antirollback protection. I don't imagine switching firmwares would work very well at all

It not a rollback technically it's more of a sideways move but I might be wrong. Is it because of the older bootloader on the firmware I want to switch to?
Thanks for the reply.

If you attempt to switch your bootloader to an older version it can cause a hard brick putting the device into EDL mode but I do believe you can switch the system a bit

So there is no way to change the firmware? Is there any way I can get volte

You should be able to swap the system partition and CSC to something else as long as your not in any kind of Android Verified Boot

I don't know what that is. But I've only been using stock ROMs from ota updates. My phone isn't rooted either. I just want to activate volte on my phone. I would really appreciate if you could help me.
Btw thanks for the prompt replies.

You're absolutely welcome! I'll have a search around Google and maybe point you into the right direction. I'm sure there is a flashable firmware for Odin (combo-firmware) that enables this
EDIT:
Because your on an International chipset (Exynos) you can actually flash a custom OS which supports the Volte. Just ensure you've taken the steps to unlock the bootloader through the developer options in settings (enable OEM unlock)

Don't unlock your bootloader and dont root your phone
if something goes wrong the EFS patition will corrupt and you are on U8
U7 combination firmware is not available and we dont know when will it will be available
you have to download U8 rom and flash home csc from U7 INS (latest software available for India)
it will enable Volte on your phone
make sure to tick nand erase when flashing Autoboot and f.reset time

Unlocking and root have nothing to do with the EFS partition. Sounds like you may have did something like modifying it and caused data to be corrupt and you never kept a backup.

once i root my device then after monts i decided to go back on stock
then after some monts i decided to try NFE 9.0 Black Diamond after that i get many errors and made a mistake
6 monts before i didn't know things now i know things like bl and opening and booting phone wihtout bl and many more
its the easiest method to get INS VOLTE on UAE Exynos Model
My phone is running smooth but efs is corrupted that makes S/N No. none and no network
Phone is dead from march
Lets hope for U7 and U8 combination firmware

Thanks for the help. Really
Volte used to work before the Oreo update. And won't a custom ROM trip my Knox? (I use secure folder). I recently tried to flash a stock ROM with modified CSC file to get volte working on my S6 g920f. But it didn't work. It tripped my Knox and now my short codes don't work and CSC shows blank. Calls work though. But no volte.

You can wait for the INDIAN U8 STock and then flash it on your device with Home CSC which will surely enable volte
Remember With Nanderase f.reset time and auto reboot
Don't trip your knox i regret it!!

I would wait too if you trip Knox with a warranty then your SOL. If your lucky you won't be it's best to wait for the firmware

Well I am waiting till there is a stock firmware. But I don't think there will be an official update seeing as it's an old model phone and the official software support is only 2 or 3 years from the company. So fingers crossed. I might flash the ins version and try to make it work if I get a new phone and my S7 will become a spare.

And thanks for the help guys ?.
Now I'm thinking of flashing a custom ROM on my S6. Let's see ....
