I recently bought a GS5 Att model SM-G900A and attempted (foolishly it would seem) to downgrade the OS version. Unfortunately this caused some sort of issue that has forced the phone to be unable to boot or enter recovery mode. It will go into download mode but neither Odin nor Kies can seem to flash. Kies gives a falure and prompts me to recover but it wont recognize the phone to recover it. Odin always falils after Nand writing and the phone gives SW rev check fail : aboot fused 4> binary 1. After some research I suspect it has something to do with the 5.0 OS making it impossible for the 4.4.2 to flash. But I cant seem to find G900AUCU2AND3 anywhere and even kies doesn't find it. Any advice would be greatly appreciated

Hello! So after some research in the forum, and seeing that it can be "easy" to root your phone, even with a locked bootloader, I decided to look into doing this with my Verizon Galaxy Note II to get familiar with custom ROMs. I had been running on 4.1.2
Please redirect me to relevant forum information for DIY or feel free to contribute any help below. Also, feel free to shame me for not finding it myself, as I couldn't find it myself.
I used "NoYouVerizon-GalaxyNote2-Casual R515" to root my phone and about 5-10 seconds through the installation it errored out and showed "Disconnected". It stated that I needed the relevant drivers from Adam Outlet which I accepted to download, but I did not re-recognize my phone afterwards while in the download screen. But, since it error, I get the incompatible firmware yellow triangle of frustration. I can't seem to use any software such as Odin, most likely because my bootloader is still locked?, so I'm going to ask you experts for help while I research a way to get it out of this mode.
Edit: Also, I have the issue where Odin states "Can't open the serial(COM) port" which causes a failure. Attempted to flash root66_VZW_Stock_etc
Edit2: Was a Samsung Kies issue. Uninstalled and able to start root66 on Odin. Processing now
Edit3: Was able to wipe/reboot in recovery mode to get back to stock. Now I'm curious of why Casual had the error. Any suggestions from the error file uploaded?
Edit 4: I have my phone back up and working with root access. Though I'm unsure how I have root access without doing much to unlock the bootloader from verizon, I guess this works. Any commentary welcome.
Any help would sincerely, 100% be appreciated!
I am using a Samsung Galaxy S5 G900A. I was unsatisfied with android 5.1.1 so I decided to downgrade. I followed this method: http://forum.xda-developers.com/showthread.php?t=2785363
Now my phone says: "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again."
Kies says that the connected device is not supported. However, Odin still detects my device, but keeps failing to load Android KitKat. At this point, I don't care what firmware I'm using as long as I get my S5 back to normal. Please help.
You absolutely can not downgrade that phone. The locked bootloader prevents this. There are no work arounds. You can only use the same build version or newer of the software.
Thanks, I followed part of this method to restore my phone:

Hi , try to put your phone into Download mode , and use latest Odin version in order to re-flash the latest stock version of OS if you are note sure which one is , just send me 7 and 8 number from imei ...
Thank you for your answer, I managed to fix my phone by flashing the latest firmware. I was downloading it from a website and it turns out it wasn't the last one.
After I looked on different site, I went on sammobile and I downloaded the latest version, It took me one entire day, the download speed was slow AF and my internet connection crashed in the middle of it.
I had to ask a friend to download it at his place and then, bring it to me.
I'm really happy, I managed to fix it.
Hello all, Ive been reading on these forums for years and ive always been able to find an answer using the search feature. However, Ive finally found a problem that I cant solve with a simple search. I was given a samsung galaxy j7 crown sm-s767vl that the person tried to remove an frp lock with miracle thunder. Now that I have it, It doesnt boot into android or recovery. The boot screen only says "An error has occurred while updating the device software. Use the emergency recovery function in the Smart Switch PC software." It will boot into download mode though. Ive tried the recovery function in smart switch, but to no avail. Ive downloaded multiple stock firmwares, combination files, and repair files for it. Ive also tried to flash it with just the stock boot .img and stock recovery.img with odin. no matter what I try to flash with odin I get the same error " Kernel rev check fail. DEVICE:5 BINARY:1 (recovery)". I know im just not getting the right firmware, I had a similar problem with a galaxy S8, but I had it when it would still boot into android so I was able to get the exact firmware needed. this j7 crown doesnt boot into anything but download mode. heres all the info I can get from download mode.

Any help or guidance you guys give me to finding the right firmware version or fix this problem would be greatly appreciated. I have fixed or rooted many android phones over the years and have bricked a few, but have always been able to recover them with the help of XDA solely. Or even possibly an explanation of what im seeing on the downloading screen that pertains to the right firmware version
thanks

I attempted to flash my SM-T970 XAR with stock firmware using Odin. It failed, and now says "An error has occurred while updating the device software". Is there any way I can recover or have I just bricked my S7+? Any help would be greatly appreciated...
Try the Samsung smart switch(PC) to recovery if not you need fine the frp hijack by hagard do recovery(sofebrick)...reboot it will got you back to download mode.
Smart switch was unable to locate the device, but I tried flashing again using Odin and it worked this time! No idea why the first time failed - I did it exactly the same way.
