ATT SM-935A - Bootloop/RFP/7.0 - AT&T Samsung Galaxy S7 Edge Questions & Answers

First I would like to thank those who will take their time to help me with my noob mistake. I have some experience jailbreakin of iphone 4s. It has been over 5 years since I have bothered to mod any phones/consoles. And this is my first attempt on an android. I can follow clear instructions/links/download/execute. My problem lies in wondering outside of those instructions when the current situation doesn't match the path I should be following. So now I will attempt to clearly provide my problem and the steps that brought me here.
ATT Samsung 7S Edge SM-935A 7.0 RFP
I first attempted to downgrade to 6.0 via ODIN and ADB. I failed at all versions and firmwares. All attempts ending in a FAIL in ODIN. ADB proved to be worthless in my hands also. I then came across a Odin PrinceComsy and managed to load Samsung_G935x_QC_Rooted_BOOT.tar Now the phone is in bootloop and feel its time to call on the experts to drag me out of this quagmire that I have created.

I managed to find the correct version of ODIN, 3.12, and reloaded all 7.0 files. Now for my luck on the FRP.
BTW I did a factory reset of the phone BEFORE purchasing. Didn't know that the protection was so far into the system and I didnt see the need in waiting for "installing apps" to complete...in my mind it was a clean phone. Silly me.

[Solved] Stuck on boot screen "samsung logo"

]I know this is a wide issue on many devices, but i could not find one for the Galaxy Note.
So here it is (and sorry if the answer is allready out there):
i roomed my phone, before i even knew what i was doing. I started the phone, and everything went nice. And then i tried to update the OS without using rooting, which appairently did not work. So i factory reset my Note, and it got stuck on bootscreen (the samsung logo). I have figured out (or atleast i thing) that the OS is missing, or something like that. So i downloaded it from a forum page here on XDA. The thing is i can't figure out how to put it on the phone. I tryed using ODIN. Any clue of an easy way to do this?
Thanks in advance

Solved:
After 2 hours of searching the internett, i finally figured out how to return to the basic firmware. I downloaded a stock firmware for the Galaxy Note, and followd a good tutorial on how to install it using Odin. Thanks to whoever wrote it:

Samsung GalaxyNote 2 AT&T - Always Stuck On Galaxy Note II Screen

Hey all,
I have read all over the place but I honestly get more confused the more I read. I wanted to switch to another OS since my phone was starting to become bogged down (too many pictures, videos, old files, etc etc etc; My phone is my work tool since I'm a field sales engineer)
So I went ahead and rooted it with ODIN 3 v1.85 and I317-UCUBMK6.tar.md5. I also installed TWRP although I have no clue which version it is. I suppose it's the latest one. My bootloader is 4.3 (I think; I go to About Device and I see the android version 4.3)
I always do the full swipe and a NANDROID back up. However, when I flash a custom ROM, I always end up stuck on the Samsung Galaxy Note II screen. It won't go.
I have tried to install the following ROM's:
DN3 - Always says "Failed" when I try to flash, even when following instructions of reboot recovery and flash again.
JEDI X 20 - Go through the entire aroma installer - it installs - asks for reboot - when rebooting, stuck as Samsung Galaxy Note 2 screen
and it pretty much happens with all of them. I have decided to back to stock (because I was a retard and accidentally deleted my NANDROID backup) and now I find my WIFI is broken.
I pretty sure this has all been discussed in various threads but I rather bring it all into one so that all that are having the same issue as me (I read a lot of people complaining about this issue with very scattered replies) can have a single thread that addresses how to fix this.
Any help will be greatly appreciated.

Stuck on Recovery Boot Loop after Rooting

Hello there,
I am having a little bit of an issue with a new Galaxy Note 4 that i got for my wife. We both bought our devices yesterday, mine from Three, and hers from EE (we are in the UK), both SM-N910F, so i proceeded to root my device and it worked all great. So earlier today i started the exact same procedure, unfortunately, my wifes Note 4 got stuck in a Recovery Boot Loop, and i genuinely don't understand what is happening.
As for the rooting method, i went with the [SM-N910*] CF-Auto-Root and choose the right .tar file, or else it wouldn't of had worked on the first device.
I have read quite a few posts, saw a few videos on youtube, but it far beyond me. I have seen a few people mention that i need to download the German (?) version of the Stock firmware, and then flash it. I seem to have found a link for it on SamMobile but it's gonna take 5 hours to finish, and i don't understand why i would download the German Stock firmware, is that the correct one for her device ?
At this point, is there any way around it ? Why did my device which is the same work perfectly, but not hers ?
I would appreciate any and all help, if you could make it quite detailed for me i would appreciate it even more.
Thank you!
Hi @Vaskie!
Can you enter in download mode?
Hello there @_mone, the following has happened since i posted:
Went ahead and flashed the following: N910FXXU1BOB4_N910FOXA1BOB4_N910FXXU1BOB4_HOME.tar and it made the device reach the home screen, from there i attempted to root using the same method which worked, but it ended installing a few extra applications, which i don't understand how. I also don't understand how flashing a new stock rom didn't make me start the device from the beginning, it already had all my information and went straight to the home screen ready to use. I feel quite confused if im honest.
On the other hand, most things seem to be working perfect, but i am having some issues with the front camera. I have two Note 4s, both bought yesterday from the same place, but one was flashed with the Stock rom (N910FXXU1BOB4_N910FOXA1BOB4_N910FXXU1BOB4_HOME.ta r) due to being stuck in a boot loop. The front camera seems to be massively over exposed compared to the other Note 4, not just a little bit either, making it almost unusable.
Would anyone be able to help ?

That's because you "dirty" flashed a new ROM on top of the old one.. it was like an "update".
What I suggest you (because you already rooted your phone and your knox is 0x1) is to flash TeamWin Recovery Project from ODIN and then flash a TW ROM from the Galaxy Note 4 Android Development (Snapdragon) page
To do so download "twrp-2.8.7.0-trltexx.img.tar" from here, put your phone in download mode, connect it to the pc via usb, from the pc launch odin, let it recognize your phone, add the downloaded .img.tar file on the pda button, click on the "start" button and let it flash the recovery.
Now download a TW ROM like _alexndr's DevBase from here and this modem and this bootloader.
Then put the downloaded ROM (N910FXXU1POF2_DevBase_alexndr.zip) in your external SDcard. Reboot your phone in recovery mode. From TWRP go Wipe/AdwancedWipe/ and tick DalickCache, System, Data, Internal Storage, Cache and "Swipe to Wipe". After go back to the first page, hit "Install" search "N910FXXU1POF2_DevBase_alexndr.zip" in "/external_sd" and install it. Wipe Dalvick and Cache again and reboot into download mode. Again connect your phone to the PC and launch ODIN now put the downloaded modem "CP_N910FXXU1POF1.tar.md5" in the CP button and the bootloader "BL_N910FXXU1POF2.tar.md5" in the BL button and click on the "start".
Once it is done switch off and on your phone and start again with the latest samsung rom for N910F already with root, busy box and all the fixes by _alexndr
And let us know if you still have problems.
Thank you very, very much for the very well detailed reply @_mone
I will attempt to go ahead with your explanation tomorrow. Would that somehow fix the camera, and i guess the other question is.. is the front camera issue that i explained myself above to do with me "dirty flashing" ?
Is there anything inherently wrong with "dirty flashing" ?
Thank you yet again!
Nothing wrong with dirty flashing.. but sometimes doing so you can create conflicts between old and new rom or leaving "bugs" from the old to the new generating problems in your new os that may wont be there if you performed a clean install. :good:

Samsung Galaxy S5 (G870A) Bootloop Fix!

I've recently found away to fix a Galaxy S5 Active stuck in a boot loop. (This method only works if your device is on lollipop 5.0! )
Note: This method only works on the OC5 update.
More firmware support coming soon.
What happened: I accidentally made my Galaxy S5 Active get stuck in a boot loop. I couldn't find a solution for the longest time because the bootloader is locked. Time passed and I eventually found away to fix the boot loop if your devices is running Lollipop 5.0!
Solution:
1. You should always try to fix the boot loop by booting into recovery mode by holding down the Home+Volume-Up Key+Power button. Once the phone logo pops up on the screen releases the power button only, but continue to hold the Home+Volume-Up Key. If it worked is should say "Booting into recovery." or something along those lines in blue letters.
Once you're into recovery use the volume keys to navigate Up and Down. Find wipedata/factory reset. Select it with the power key and navigate down to Yes. Wait till it finishes. Then see if that fixed the problem. If not proceed to next step
2. Since the boot loader is locked it's really difficult to flash any kind of Recovery, ROM, or Stock Rom unless your phone accepts it as a valid file. So here's what you do!: (Method 1)
Download this file and save it to your desktop: https://drive.google.com/open?id=0B3UBRFq3BojVQnBSc3lCSzloYUU
Download ODIN v(3.09): http://odindownload.com/Samsung-Odin/#.VgiJ_8tViko - Extract it to your desktop.
Put your phone in download mode. (Note: Before you do this, install the correct drivers for your phone to your computer.)Make sure your phone is completely off and Hold the Home+Volume Down+Power. You will get a warning message just press the volume up key to continue.
Go to desktop and launch ODIN. After ODIN pops up, plug in your device. (Make sure you have the correct phone drivers installed)
You should see a dialog box in ODIN that say 0:[COM6] in blue. Note: It might be different for everyone, just make sure it says COM.
After that, Under "File [Download]" click "AP" Then navigate to the file you downloaded earlier called "boot.tar"
MAKE SURE RE-PARTITION IS UNCHECKED!
Leave everything else alone then click start. Wait till it says PASS! in green letters in ODIN!
(Method 2):
Go to this link download it to your desktop and follow the instructions: https://drive.google.com/file/d/0B3UBRFq3BojVdXlSUE43VzJPbEU/view?usp=sharing
Done! Your device shouldn't be in a boot loop anymore! If you have any questions let me know!
Note: Once this process is complete, your phone will permanently show a warning in your notifications saying "Unknown action detected." This happens because your phone will detect that your kernel was modified so if you don't want this to happen, then I suggest you wait for a official lollipop OS release.
UPDATE!: You should now be able to download the "Boot.tar" file. Sorry about that!
UPDATE!: New files and instructions added if the first method didn't work!
Having some major issues
First post so forgive me if this is misplaced. Before I was aware I'm unable to down grade from 5.0 or 5.1 version of sm-g870a I attempted to downgrade and apply root from version 4.4.2/4.4.4 via another XDA thread in a faulty attempt to root. At first this presented no issues until restart. At this point the phone is soft bricked and bootloops. Both download mode and system recovery ARE accessible and prior to this I had USB debug open. I have the factory cable and odin identifies the device easily. All other md5 files failed to apply OTHER than one. (4.4.4 ota) I presume because of bootlocks which I'm now aware of. I have attempted three different stock flashes via odin all from XDA all fail at authentication claiming error fused 2 binary 1. I attempted add data pull before all of this and the device ignored a request which prompted a factory reset which was odd. I have attempted installing 3 alternative stock and stock rooted 5.0 and 5.1 firmwares from XDAs threads. All of which failed, hiwever one granted me some precious Information when I slowed down the error message via recording. It states, "Package expects fingerprint of Samsung kltattactive/lteactive:4.4.2/kot49h/g870aucu1ang3:user/release-keys o0A1:user/release-keys this device has kltactive/kltactive. This tells me as far as I know that the device is showing no firmware installed and a double fed file making the attempting installation incompatible. At this point I want to start anew, I have how attempted every route accessible via XDA and feel my options are running very low other than attempting to randomly apply firmware in sequence until odin accepts one and it sticks. That sound like a brick plan however. I don't care what firmware is loaded as long as an OS is accessible. I think this is all available Information I apologize for typos I have been at this for a total of 20 hrs straight. This bootloop was a tired lapse in judgement and has cost me 5 hours of trial and error. Wiping cache fails, reformatting internally fails, as far as I know root was never successful and I THINK philz was successful installed although at this point I cannot recall. Thanks for reading and in advance for any available help. I have SOME c# experience and some java script which is zebra vs dolphin situation I only mention as to aide and explain my trainers of thought. All other languages are vague at best
Edit: I stopped bootloop with the file attached to this thread. It now boots into samsung display bht will not go further and stops there as though it still has no operating system.

Alright this stopped the looping now, to find a proper rom. I believe. Im going tohave to wait for 5.1 in order for it to be successful, however is having 4.4.2 still on it is a bit worrisome, I predict overwriting it should be fine though. Thank you for giving me a way to at least resolve bootlooping. I believe I shoulda have safestrapped the device, but hindsight is always 20/20 eh?

I'm glad you got past your Bootloop! If you need anymore help let me know.
Is there a way to root my galaxy s5 active [G870A] on att with 5.0? I'm getting conflicting info and not finding the root.tar I need to flash in order to roll back to 4.4.2 so I can root. Right now I'm just trying to get root. Thanks for any help or direction.
S5 Active
I'd say hold off for a while I did that exact 5 Hong with the s5 active and it bootlocks it. You need to, if you're going to do this install and use safestrap to di so and BACK UP EVERYTHING with safe strap to SD. As long as you follow those method you SHOULD be able to even soft brick it and come back from it.

I haven't found any successful way to to go back to Kit Kat or 4.4.2 for this phone. In fact that's why this thread exist is because people who have tried to flash back to 4.4.2 have failed and got stuck in a Bootloop. So if you plan on trying to find away make sure you back everything up and if you fail you can use this tutorial to get your phone working again.
Make sure you have "USB Debugging" on
Make sure you have the drivers for your phone installed on your PC before you start the process of looking for a root.
Yeah I tried flashing back to 4.4.2 and it was a no go . I had the stuck on 5.0 issue where download mode says "downloading do not turn off ...... " but after I wiped my phone I was able to update to 5.1.1 successfully without any "download interrupted "errors . So at least I'm not stuck on 5.0 now lol

There should not be anything attempting to download when you boot into ''download mode'' if there is, its highly likely there are still particulates of the last bad flash. I would as he said above, enable USB debugging and the like, and install safe strap to be safe. After safe strap is done and youve followed the tutorial which you can find in another thread on this site, boot your phone down and then power it back on, safe strap should come up first, when it does so push the ''recovery'' option to enter safe strap( someone correct me if thats wrong, my phone is currently dead/charging so i cant check) From there you can back up to an SD card, make sure you enable compression when you do.
Once thats done, WIPE YOUR PHONE, and Cache,( maybe dalvik as well if you cant find it dont worry.)and its all on SD CARD, then attempt to dirty flash( I dont recommend), or clean flash your device WITH safe strap. This typically entails downloading a .zip file and opening it THROUGH safestrap, which is done the same way as backing up your data, only via another option in the menu. Simply put; Back up data with safe strap, after thats done push back and choose FLASH, it should show you all available items it can flash from/to, pick and pray. I didnt go this route when I tried, I attempted to brute force the Bootlocked S5A, and it caused some errors that I now have reversed after much pain. If I HAD safe strapped, It may have went smoother for me, and may for you. Safestrap for us Samsung users is the same as Clockwork Mod for the rest if you weren't aware.
I'll edit this when my phone charges and I can walk you through appropriately, if need be MSG me and Ill do it as soon as I receive the message via this thread if I have not already.
hi guys! good day! i have tried the new method twice! and odin fails everytime! the problem is with the modem.bin! is there any way to fix this?
Make sure you're running lollipop and not Kit Kat and make sure you have the correct phone model. If you don't meet both those requirements then it won't work.
it has on lollipop recoverymode comes up with LRX21T.G870AUCU1B0C5. ISNT that lollipop? download mode also says ;A2, P1

Yeah that information is correct. You might want to download the latest version of ODIN and try again. (Make sure you're putting the modem.bin file in the correct spot in Odin.)
I think I have the latest odin.. And modem can only fit in the cp field I think. Its just not working for me. I tried doing each part separately. And the modem flash always fail.

Hey irontac. Since you came up with this fix. Are you able to tell me why those s5 go into bootloop like that? By the way mine is not in bootloop. It hangs on the AT&T logo (the glob) . I was thinking maybe I need to flash the system.img , but where can I find that. And how can I flash it by itself? Actually the phone belongs to a friend. He seems to have rooted it. But I don't know what else he messed with.

You might want to boot into recovery mode and try to factory reset it normally. If his phone is rooted you could also flash a custom rom to it and get it out of Bootloop.
I also forgot to mention you can't get ahold of the system.img because it's not released to the public.
Yeah. I wanted it back to stock. I downloaded the 5.0 cfg file. Opened it up and I realized that there is no system.img in there. Oh Well. You think it would boot if I used kitKat system.img?

If you flash the Kit Kat system.img you might have to downgrade the kernel also. I would give it a try and see if it works.

Can get to CWM Recovery, but can't sideload

So, I can't remember what I did to this device, exactly. I got it already in a bootloop. I had seemingly fixed it for a few weeks, but then it started rebooting randomly and then eventually got into another bootloop. I can't remember if that just happened one day or if I was trying to fix the random reboots.
I stopped working on it when a family member gave me their old Nexus 5X. But the other day my Nexus 5X entered into a bootloop because of its well known hardware problem (I think anyway, I wasn't doing anything that should have bricked it). So I decided to pull out the old Galaxy s5 and see if I can fix that instead.
Normally when I flash ROMs onto devices, I do it when the process for the device is pretty well established. As we all know, Samsung devices aren't the easiest to work with. So I remember having to do a bunch of extra ****, download Odin and so forth.
By the way, I have the AT&T G900A version. I boot into recovery and see that it boots into CWM, thats good news obviously. I pick "update through adb". I run ADB through command prompt (btw, someone should update the guides on this site to mention that Powershell doesn't play nice with ADB commands, that was like 20 minutes of hair pulling frustration) and it recognizes the device. I wipe all the user data and cache etc and attempt to flash a custom ROM I found on this site: APTOS found here.
I get an
Finding update package. . .
Opening update package. . .
Verifying update package. . .
E:footer is wrong
E:signature verification failed
So then I downloaded the stock firmware ROM titled "SM-G900A 4.4.2 G900AUCU1ANCE Firmware.rar" and get the same errors.
So, obviously I am forgetting something. I know there are a lot of guides on here and the answer is probably out there somewhere, the problem is that most of those guides are for people starting at square 1 without CWM or TWRP installed. Can anyone help me from where I am at? I uninstalled Odin a while ago but could definitely reinstall it. Was hoping to do this from where I am at, since CWM is already installed.
Anyone have any ideas on what step I'm forgetting? Do I need to flash other things before the ROM? Should I just start completely over with ODIN and the rest of it?
P.S. I have more experience with TWRP than CWM but I remember having trouble getting TWRP to work but did manage to get CWM to install as an alternative.
Thanks in advance!
