[Q] AT&T Wipe, flash stock? Still root?

EDIT: FULL STORY BELOW. SKIP TO SECOND REPLY FOR UPDATE!
900A, AT&T, WAS 4.4.4. I rooted my phone with towelroot by downgrading via ODIN then reflashing 4.4.4. I've had the phone for a year and wanted to experiment with some custom roms--specifically Twi5ted Lollipop. The version I found last night was V3. Anyways I followed the instructions of installing safestrap then attempting to create a partition to host the mod. Every time I tried to boot the partition I would wait 12 minutes with nothing but a black screen (I presume a bootloop.) After reading some posts here I found it requires a clean flash--not a dirty flash. So I used safestrap to backup, then I wiped it and installed the mod. Nothing--still black screen. I then attempted to restore the backup I saved--fails every time.
At this point being the noob I am, I started to get very concerned. I went into advanced wipe and for some reason selected 'system' and wiped it. After a reboot, it shows the Samsung logo, goes blank, vibrates then goes back to the Samsung logo. I went into the standard bootloader and attempted to restore to factory settings but there is nothing to restore of course cause I wiped everything.
I'm currently at work bored as heck cause my phone is wiped. I can still go into download mode thankfully. Should I have no problems flashing stock via ODIN when I get home on my lunch break? Which stock firmware should I flash for this phone?
Thanks!

Unfortunately my lunch break brought me no good news. I downloaded stock found here: http://forum.xda-developers.com/showthread.php?t=2714455
After I flashed all the files (Except BL) when it boots, it get's to the Samsung logo--freezes halfway through then goes blank with the blue LED light on. I waited 10 minutes just to see what it does with no luck.
Another thing I found was weird-why when I boot does it still say 'Custom' when I flashed the stock firmware?
I really hope I don't have to drop $650 on a new phone Any help would be incredibly appreciated. Thanks guys!

why didn't you also flash the bootloader?

AT&T bootloader is locked right? Regardless I tried flashing the bootloader as a last resort and ODIN failed. Figured it just confirmed what everyone else said that it's locked.

Is there a specific way I need to flash the files? Like one at a time?
Do I need to restore factory settings/delete cache THEN flash each? or vice versa?
Am I basically screwed since I have AT&T?

FIXED!
After flashing 4.4.2 several times and trying different things, I came across this thread which finally brought my phone back to life. Thanks XDA!!!

Unable to flash stock firmware

Hello, my SM-G935A is rooted, and I have 2 issues with it. Firstly, I'm unable to receive texts or phone calls (I can send them), and I've tried a factory reset and I even got a new SIM, but nothing worked. I think if I flash stock firmware, it might fix the issue. Second problem, when I go into download mode and select my AP in Odin and press start, my phone gets an error and Odin freezes at Initialization.
Any help would be appreciated. I would prefer to fix the texting issue, as I don't want to return the phone to ATT. In either case, the Odin issue needs to be fixed

I'm having a similar issue. This afternoon, 2 apps threw errors and closed. I rebooted, which apparently was the wrong thing to do. The reboot stalled on the AT&T logo and stayed that way for 5 min - the unit became very hot & the power button did not respond, even while holding it down. I got into recovery, cleared the cache and factory reset, then rebooted. The unit came back up and started reinstalling everything. I took it back down into the download status and attempted to reload 935x via Odin, only to stall at "initialzation" [sic] as you did. I got out of that after waiting for some sort of response. SuperSU was still in my apps as was Root Checker. Root Checker indicates the system is rooted. SuperSU indicates it needs the binary updated. BusyBox and TiBu indicate they cannot find root. I deleted all the root apps and tried reinstalling root via adb which completed successfully, but the same outcome with all the root apps. So I'm not sure if I'm still really rooted as Root Checker claims, or not.
EDIT: I just saw that I have 2 "Knox Settings" apps. Clicking on either returns, "Unfortunately, Container Agent2 has stopped."

use the odin from the stock firmware thread to flash it again. if it fails you can flash the u firmware and then the stock again. then you have to use a different odin if you want to flash the root api file the one you flash the firmware with wont work. also there is help in one of the threads about fixing the volte problem so you dont have to turn it off to get calls. i didnt have to do it as using the odin i mentioned fixed it for me when i came from the u firmware.

I was having the exact same problem you had with Odin. It seemed I was able to flash stock firmware using this version of Odin: http://www.mediafire.com/download/2t2sjqxtogbkafk/odin_3.12.3.rar

did you have any problems with the u version of the s7 edge firmware, like the fingerprint scanner not responding? i am on that version and cant get any odin version or any version of s7 edge g935a firmware to flash, tried unrooting and was forced to use the U version of the s7 edge firmware, everything works except the fingerprint scanner, cant get back to full stock firmware, need help!

im having the exact same problem, when i put my phone into download mode and flash the stock at&t firmware, Odin get stuck in "initialization" and my phone screen displays and error message.

Same stuff was happening to me, I went back to stock and took the update. When your phone stops working as an actual phone, it's time to roll it back.
I played with it for a week and my phone was so freaking hot (with hot weather) equals a wait and see if this gets more stable in the near future. I did use the Odin 3.12.3 mentioned by King James III. Honestly, I did so many things to get it back to stock I forget what actually worked (it was the wee hours of the morning and I was spent). Don't give up guys, it will and can work.
edit: It may be as simple as not right clicking Odin and running it as Administrator.

I used Odin_v3.12.3_Patched_SHA256 to flash the 935U Firmware then used Odin3_v3.11.2 to flash the June Firmware release.

Note 4 (SM-N910F) Bricked

Hello there,
I've spent my entire day trying to fix my Galaxy Note 4 (SM-N910F), without much success.
So what happened was that the phone would occasionally freeze, turn it's self off and reboot into download mode and say that it wasn't able to boot normally. But it usually just booted after pulling the battery.
So I thought I would just try to install the stock firmware(4.4) and go from there. And that worked fine (eventually) but the problem remained.
Why not try again, I foolishly thought. So I tried to download a more recent firmware(6.0), but it wouldn't install completely. It got stuck in Odin around half, saying: "FAIL!(WRITE)". Tried again using the older firmware(4.4), but the same result.
Now whenever I try to turn on the phone it immediately jumps to download mode saying that something went wrong while installing the firmware.
I have done a couple of things to try and resolve this issue:
- I have tried to flash BL,CP,AP and Pit from a recovery firmware without much luck.
- I have tried using Odin 3.09 and 3.11.1
There was one thing that kinda helped once, which was flashing twrp and all of a sudden it worked and actually turned on. But genius me decided that I had to try again and update to the newest version. Which wasn't really smart because again the flashing of the firmware failed.
If anyone could please help me out. I have spent nearly two days trying to fix this darn thing. I really just want it fixed

I hadn't, I google searched multiple times for such a topic, but didn't find any.
Besides using the SD card to flash the firmware I had already tried what was listed there.
But for the sake of it, I tried again. For some reason, this time it did work!
Many thanks for the tip!
I'm just left with one question, the recovery firmware you provided in the topic is german, but I have a Dutch phone. Will that create any issue's with network connectivity?

First, flash that recovery firmware, once your device starts working normal, flash your region specific stock rom from sammobile.

Thank you so much for your help. I tried to see if the initial problem was resolved, but it still isn't. The phone sometimes doesn't boot and goes straight into download mode. I'm starting to think that it's a hardware issue, but I'm not sure. Any ideas?

Must be hardware.
Anyway, i would do this
- flash twrp for Note 4 (look for it) from odin
- fladh rom from twrp (not from odin)

Help - Stuck in Infinite Bootloop

Hi, I have an old N8010 16GB which was bought from John Lewis in the UK (an official retailer). The tablet has worked great, however recently it screwed up and got stuck in a bootloop.
So I decided to see if I can try to recover it and that's why I am here. I tried Odin and started putting what I thought is the correct firmware on it, however all the firmwares I try all PASS and seem to install correctly but the device still has a infinte bootloop (it crashes and reboots after the Samsung logo shows). I noticed the PIT file says -8G on one of the firmware files - I guess this means it is for the 8GB version which is clearly not going to work on my 16GB version?
Please can someone guide me on what firmware to download and what to try as I have been trying for 5 hours now and cannot find any way to get it out of this boot loop, I have no problems at all installing firmware as it passes every time with Odin. I am using Odin3 v3.10.7
I'm not sure but I think I need this firmware: N8010XXUCMG1

Hey, I had the same problem recently and I fixed it using the stock firmware (can't post the link due to forum rules) and using a patched Odin 3.14.1 3B.
Hope it helps

Lets hope the OP has fixed the problem in the last 10 months .Unknown as he never came back .

Device not starting/black screen after stock-ROM flash via Odin

Hello, everyone,
I tried to install LineageOS on my S10 Plus yesterday. That worked so far, but I found that it didn't have a decent camera app and the Samsung Watch wasn't that easy to connect either. So I thought I'd just go back to the Stock ROM again. I then downloaded the latest stock firmware according to this guide and installed it with Odin. The installation also runs through, after the installation the mobile phone starts and after the start screen there is an Android man with the signature "Erasing". After a few seconds, the device turns off and stays black. Even if I put it on the charger or try to restart it, nothing happens. I keep getting into download mode and recovery, but that's about it. Multiple reinstallations and resets via the recovery didn't help - the phone just won't start.
I used the CSC_... and not the HOME_CSC_... at the firmware is the right one for my phone.
Is there any way I can salvage the device? I'm afraid that something in the memory is defective now, which has nothing to do with the flashing itself. Do you have any ideas?
Many thanks!

Thanks a lot, this worked!

I'm glad it worked.
I was very afraid that the phone died, what did you do for 5 days in this state?
Now I have a question in my mind: When Samsung releases an update in the future, will the bootloader and modem files be updated when we update it with odin? won't it be updated? After that, do we will always update manually as twrp? do you have any idea?

Well, I simply didn't use a mobile phone in these days. It was a very "interesting" experience, but not a huge problem. I sometimes opened WhatsApp as Windows App (interestingly, which works without phone).
I don't know, what happens at a Samsung Update, but until Android 13, I will not update (so probatly never). In our German forum (www.android-hilfe.de), a pre rooted and debloated "Stock"-Firmware is provided, but I can't install it, since my Bootloader is too new (V15 instead V14 for the ROM). When it is possible, I will install this firmware. If you are interested, here is the link: https://www.android-hilfe.de/forum/...3-2022-stock-rom-v2-0-pre-rooted.1000713.html
