Need Help. Bricked phone after trying to rollback to 4.4.4

So I was trying to rollback to 4.4.4 from the latest Att update 5.0.1 that we got a week ago. Now my phone is stuck in Download mode and does not reboot. I even tried the Keis method with no luck. Still keeps going back to this screen with this error.

I kno this might not be much help, but with the latest AT&T update 5.0.1 COC5, I think you can't rollback to 4.4.4
I kno 100% Verizon latest 5.0.1 you can't rollback either...
But for all these reasons is why I'm still on 4.4.4 NK3 update had this update since day one I bought this phone
But hope the best luck to you... you might have to install 5.0.1 again

If I need to return phone to fix? Who should I deal with AT&T or Samsung. I was going to blame it on the latest software update.

Flash the new firmware back onto your phone. ..

I could not flash anything. It just kept failing. I even tried kies method with no success.
So I called AT&T and blamed it on there latest update. Took it to an AT&T warranty store and they gave me a new note 4. They tried to flash with there software and had no success either.
So I walked out with new note 4. So beware people do not try to rollback if you accepted att latest update. You will brick device. [emoji20]

hi guys,
looks like i just did the same thing. I was trying to downgrade my wife's AT&T note 4 since she's been having tons of issues with this phone (this is actually her second note 4). anyways, long story short, i am now stuck at the same screen you are at. i've tried odin 3.09 and downloaded the COC4 files (4 files, BL, AP, CP, and CSC). and when i run odin i get an error message, and it fails to install.
here's the message i get:

Try with out BL file.

senseless returns like these two are what makes modders look bad in their eye; on the other hand if the bootloader was unlocked and they didn't lock it down so tight they wouldn't have these issues as well

Making up a lie and committing Fraud is not something I recommend doing.
It sucks but if you mess around with your device and ruin it/can't fix it then take responsibility for what you did.

Get off your high horse. If att didn't lock this phone up so tight we wouldn't have these issues. If you don't want to do it don't go around judging others.

If you did your homework, you would have known not to downgrade. It's irresponsible people like yourself that have caused these phones to be locked down. It's also the reason we are now paying so much for them. And finally, davidstech11 was accurate with his comment. Course it's not human nature to do the right thing which is what makes those that do stand out from the rest.

You're using the wrong files. You must use the same OS files that your phone is on or newer OS files. It's showing that the authorization is not letting it write to the system because it's not the right files.

Help: Reverting the SM-N930A Battery Update

Alright so I'm trying to figure out what I'm doing wrong. I downloaded a copy of the pre-borked Note 7 firmware and I'm trying to flash it through ODIN. Every time I try, I get errors on both the phone and on the software.
I've been Googling all day and I can't find an explanation or a workaround. Can the experts here help with this?

for the Samsung Galaxy Note 7(SM-N930T), by freeza

Good thing it failed, thats for T-Mobile, if it completed it would have bricked your phone. I am searching also for the AT&T version

I believe that the SM-N930P version is for Sprint. My carrier is Sprint

From my understanding, the firmware available online, which ends in PH1 has the old bootloader. Once the battery warning update hit (Green Battery Icon for those who have the replacement model) the firmware came with a new bootloader and firmware version ending in PHE.
Because of this, we cannot flash PH1 due to the bootloader change.
The 60% battery update (PK1), I BELIEVE, still uses the same bootloader as PHE.
The only solution I think would be as follows:
1) Immediately disable any future software updates. (We dont want another bootloader change)
2) Someone needs to find and or upload the PHE version firmware (which lets you charge 100%, and only has the annoying original message sometimes)
3) Backup everything.
4) Using the methods described in other places, flash the PHE version, charge to 100% and deal with only a few warning mesages. (Phone startup and Attach to charger)
4) Immediately disable any future software updates by following the instructions for Package Disabler PRO or EZ Disabler. (Making sure you're on airplane mode, SIM card out, and wifi is turned off)
These are my thoughts. I cant seem to find PHE firmware anywhere. One place has it supposedly, it seems shady cause the download link goes to an arabic website and the forums require you to pay for each download. (hmmmm.....)
I could be 100% wrong, Im not an expert by any means, just another user trying to join the community to help find a solution. Can anyone confirm Im wrong and they have been able to somehow flash the PH1 baseband firmware? Any and all help would greatly help me and the many others who have been held down by the man

SM-N930A Update
I have the N930AUCS1APH1_N930AATT1APH1_ATT_FULL_SAMFIRM.NET ROM with 4 .md5 files in it (BL, AP, CP, and CSP) and I can not get the phone to flash using Odin 3.12? Any ideas on what to do? This is my log, but basically just says failed!

Here is the PK1 firmware image
Hey guys, I am going to give you guys looking to get back to 100% charging a good new. I found the PK1 image for AT&T Note 7 N930A version. I just re-flashed my phone and it worked just fine. Got to charge my phone back to 100%. Got the green battery sign back. Here is the firmware image.
androidfilehost.com/?fid=312978532265363403 (I had to skip the www prefix because I am not allowed to post url at the moment. You guys know what to do with it. Just copy and paste.
Had to use Odin 3.12.3 version. I tried with Odin 3.10.7 version but got Odin protocol version error. So use Odin 3.12.3 version. Good luck.

Sorry, my previous post should have said PKE firmware image.
---------- Post added at 10:03 AM ---------- Previous post was at 09:58 AM ----------
Got to check my spelling. PHE. Not PKE.

Thanks hachika88, that worked great. Does anyone know what I need to disable to prevent it from updating again. I have disabled com.samsung.knox.appsupdateagent and com.ws.dm, but is there anything else that should be disabled?

Use this link to go back to 100% on Rev 2 Firmware flash win Odin 3.12.4 or 3.12.3
androidfilehost.com/?fid=457084094631641284
Use Samsung Package Disabler Pro to disable Software Updates apk but you must do it fast after you reset your phone because once your phone checks for updates you can no longer disable it. Keep your SIM card out the phone and disconnect from wifi until absolutely necessary to get it disabled.
Good Luck

I used abd script to block th updates instead. A friend had her phe firmware pulled so that people could use it. If you look

Firmware flashing problem with Samsung Galaxy Note 10 plus (SM-N975F)

Dear readers,
I tried to root my Note 10 plus (Dual SIM) via modifiying the firmware with the magisk manager, later on I have realized that I have downloaded and tried to install a not supported version of the firemware on my device.
Now I am struggling to flash a blank firmware, to revive my phone, but every time I am trying to flash a firmware that is made for my Note 10 plus version (SM-N975F [dual SIM] Germany), odin stucks while flashing and my phone reports a not valid version, that was tried to be installed.
Information:
-My phone shows me on the download mode (SM-N975F)
-I have downloaded and tried to flash the firmware for SM-N975F (Android 9)
-My Android version, before trying to root my device was Android 10 (June update)
-And I have removed the OEM lock,
download mode shows, while odin is stuck: SW REV. CHECK FAIL(BOOTLOADER) DEVICE: 4, BINARY: 1

Has it to do something with the dual SIM variant, what can I do?
I’m so thankful for every answer

I think Android 10 version has higher BL version and you cannot downgrade to android 9 with lower BL version.
Try flashing the latest FW version for your phone.

Try flashing the latest version of the version of the firmware. You are trying to flash a firmware that cannot be flashed to your phone as it has an older (unsupported) bootloader.

How did this turn out for you ? It sounded correct to me but last i had this problem i was on a s7 edge dual sim exynos . I was able to downgrade at lease from 8 to 7 or some variation of nougat to a much earlier one by mixing the new modem and bootoader with the older firmware of nougat that was previosly working. I learned my lesson about upgrading the modem only when absolutly neccesary or if i am completely done playing with the older roms that are not compatible if you upgrade the modem and bootloader. If youll notice alot of times devs pf ressurection leave thier modem and bootloader on a older version than most while still bringing the newest android to all the zombie phones. It doesnt hurt to mix and match in this particular way just a little bit but be sure you understand what a modem bootloader flash and a firmware flash are and read around a bit to make sure theres no red flags and i have never went backwards more than say one version of android. But i DON'T EVER UPDATE MODEM UNLESS THERES NO OPTION TO DO IT SEPERATE AND IVE DECIDED ITS TIME TO MOVE ON to the newer set of roms that has presented itself. Good luck
I was curious if this worked for you because i just got my note 10 plus today.

What happened now. did you fixed it...

pls help, is my s9 only soft bricked or unsolvable

i got twrp on there and magisk but couldnt log in to my samsung and google accounts, an i read startin odin i had to log out first from them, which i did so i thought i might have missed something so i did it all over and now its bricked.
it started out with getting black screen with a tiny red text that i needed official rom or something like that. and it got that if i tried booting regularly or even trying to boot twrp.
so i currently can only get into download mode and it wont let me flash new twrp or official firmware. i tried flashing recovery, bootloader and other things separate and the all fail so i'm able to enter download mode but cant do anything with odin.
this is my latest odin log, it just stops and i get the error on my phone in red text looking pretty much the same, only thing that seem to change is if it says bootloader or system etc.. the odin log saying it failed doesnt show up until i unplug or exit, and i waited a few hours the first time so i knew it was a done deal before aborting it
i'll add picture of how my download mode looked as it fails and another how it looks if i try starting the phone in any other way, it tells me to use emergency recovery in smart switch for pc but when doing that my phone isnt showing up so i can't do that neither. and that screen only showed up after i tried flashing the new firmware.

i got a G960F/DS and restoring it in the beginning i always had an old 2018-2019 security patch running android 9, not sure exact which firmware but the fw zip i tried flashing was called G960FXXU2CRLI_G960FOXM2CRLI_DBT
if that makes any difference. i tried finding something something in a similar time frame as my original one which is why i chose that one.
so please help me solve this

Downgrading from One UI 2.5 to 2.1 (Snapdragon Hong Kong)

Hi,
I tried to downgrade my Samsung Note 10+ Hong Kong Snapdragon edition. I am able to unlock the bootloader through developer mode, and during downgrading, I was able to:
Downgrade to release 2020-09-27 - Which was also One UI 2.5
https://www.sammobile.com/samsung/g...e/SM-N9750/TGY/download/N9750ZSU3DTI1/372284/
Attempted to downgrade to release 2020-06-23, but got this error: SW REV CHECK FAIL
https://www.sammobile.com/samsung/g...e/SM-N9750/TGY/download/N9750ZSU2CTF1/346913/
Is it possible to downgrade to One UI 2.1 somehow?

You will see from your post that the UI 2.5 has SU3 in its name and that the UI 2.1 has SU2 in its name. That is the bootloader version number and you can't go backwards (downgrade) that. So the simple answer would be no. Sorry.

Ah, that's the reason and how I can see it.
I realized there was another release on the 5th of August with SU3, so I tried to install it. It worked, and it came with One UI 2.1! Google Cam is back in business.
