[GUIDE] Soft-bricked, or just looking to unroot (UPDATED 03-06-2016)?
- Thread starter shortydoggg
- Start date
I am not saying that towel root bricked the phone. The problem after towel root was that I could no longer read my internal SD and had apps continuously FC'ing. When I tried following the guide in this post (option 6) the Odin flash failed and THAT bricked my phone (at least to the extent that it can't boot past a recovery screen). I've tried both Odin 3.09 and 3.07 at this point with no luck. I am sure it is not the virtual machine because I just flashed a Note II using Odin 3.09 from the virtual machine.
If anyone has any other thoughts on how to proceed, they would be much appreciated? I am going to keep fooling around but may have to just do a full wipe from Kies since I have a flight to catch this afternoon.
Not the best solution but can you put the files on a flash drive and go to a friend's windows Computer and try that?
All our computers (6+) in this house are either Mac or Linux and the same goes for most of our friends! Also, just tried Kies and it gave me an error too... this is not looking good...
have you tried another ap file just for ****s and giggles?

hope this helps?
I'm lost as to why it is not working for you
Just a heads up: I tried debricking with just the AP file and Bluetooth would not activate. I ended up flashing cp, ap and csc and everything works fine now.

I had no issues with bluetooth. But regardless, flashing the AP alone is more for people who do not want to lose everything right away, or who just need the phone to boot to recover their data.

Which is why I tried flashing the ap alone initially.

I do not care if I loose root, data settings nor other stuff just want to factory original to undo everything I have done or added then if it ota's back too G900AUCU2AND3 fine/good....
If I had system img... as well as a recovery img would I be able to use that from a pre G900AUCU2AND3 ???

THANK YOU
Thank you so much for this. i traded my htc m8 for the s5 yesterday and it was rooted and had SS recovery. I wanted it stock so deleted the root and SS files and was stuck at splash screen. I tried flashing stock firmware via odin and kept failing. i got so nervous until i found your guide! worked like a charm thank you much!!!

Thanks
I searched thread after thread until I found this then I was back to stock in minutes. Can't say thanks enough, I searched for a the better part of a day and came up with about 30 things nothing worked. This thread solved my troubles instantly.

This worked for me to revert to NCE after soft brick. I used the three files and that worked. However, the firmware update to ND3 is failing. I have already rooted, installed SuperSU (disabled Knox), and froze unnecessary apps. It will download, reboot into recovery, and start the update. It keeps failing around 30% or so. Any thoughts? Should I unfreeze apps?
If you disable anything, delete anything, or have anything frozen, then the update will fail. The best thing would have been to OTA, and then root. You'd now be pretty much starting over, or putting everything back that was frozen or deleted, and likely you'll miss something. You'd likely need to re-flash the AP and CSC files again, which will factory reset the phone.
Is there any particular reason why you want the update, because the only thing that you will gain is Lookout and YP, which can be downloaded from the playstore, unless there is some performance difference that I don't know about.
I'm guessing there is a battery drain fix because my phone has been draining like no other on NCE. This never happened on ND3.
That's possible, or it could be something running in the background, or it could be just your battery.
Doubtful, to be honest. The phone is less than two weeks old, and I did not install anything different.
Also, I re-Odin-ed once again to NCE. I did not add anything. I didn't even hook up my Google account. All I did was hook up to my WiFi. I downloaded the update, and once again, at 32%, it retried once, and then came back up as Download Interrupted. I did see one forum suggesting (for the S4) that an external SD card might mess with it. Anyone heard of that?
Did you try downloading it over your mobile data connection. The update is only 46 mb. Also, do you know how to sideload an update.zip through adb, because you can be given the file.

39UPDATE 03-06-2016: This is the latest and only FULL fix for the current Lollipop firmware: G900AATT4COI5 (Lollipop 5.1.1), which cannot be rooted at this point, and should fix all current versions of the At&T Galaxy S5, including Lollipop G900AUCU4BOF2 and G900AUCU4BOF3, but likely with the sacrifice of not being able to ever root again.

You will need to unzip all of the files into a common folder. You need to boot into download mode. You have to flash the BL_G900A in BL, the AP_G900A file in AP, the CP_G900A file in CP, and the CSC_ATT_G900A in CSC. It's best to flash all four files at the same time. Make sure only Auto Reboot and F. Reset time are checked. Once the phone reboots after Odin, the operating system is updated to the latest firmware G900AATT4COI5. You will permanently loose root, however (if root is never found); and your phone will be factory reset because of the CSC_ATT_900A file.
To fix the stock partitions only, follow the thread by Birkyjon :

For all firmwares 4.4.2 and 4.4.4, it's best to use the G900A_Downgrade_to_NCE.tar file by muniz_ri also found here:

These can be rooted again after downgrading.

THE FORMER CORRECTED VERSION:
(Note this guide is mostly for Windows based computers and may not work on a Mac).
For those who've soft bricked their s5 after towel root, or just looking to downgrade (to enable the download booster fix for example, or just want to start over), and who are on firmware G900AUCU2AND3, this is a brief guide, as I don't have the time of day to make a full step by step guide.
1. You're going to need the firmware from this thread. Only use the first file download. The other, as well as the ones from Samsung-updates and Sammobile will not work.

or you can use the link from davew41 given here
http://www.mediafire.com/download/7np57282x5on1h1/SM-G900A+4.4.2+Firmware.rar
2. You'll need to extract these files. You'll likely need winrar to extract the files.
The .rar file contains 4 different .tar files The BL file is for the bootloader, the AP is for the boot image, recovery, and system, the CP is for the modem, and the CSC is for the cache.
3. You are going to need Odin 3.09.
http://www.mediafire.com/download/vwuqru9m1jp9wbw/Odin3_v3.09.zip
4. If you are doing a full downgrade, starting everything new with a factory reset, then you will need all of the files, except the BL file. BL for sure will not work, because you already have that bootloader.
You need to boot into download mode. You have to flash the AP_G900A file in AP, The CP_G900A file in CP, and the CSC_ATT_G900A in CSC. It's best to flash all three files at the same time. Make sure only Auto Reboot and F. Reset time are checked. Once the phone reboots after Odin, the operating system is downgraded back to the previous one. You will temporarily loose root (until you re-root), and your phone will be factory reset because of the CSC_ATT_900A file. The phone, minus the bootloader, will be in the exact state that it was in from the UCU1ANCE firmware, so that it is easily rooted again as well as upgraded back up again.
5. If you are looking to downgrade, but want to keep your userdata without a factory reset, then you will only need the AP_G900A file.
You only need to flash the AP_G900A file in AP. Make sure only Auto Reboot and F. Reset time are checked. Once the phone reboots after Odin, the operating system is downgraded back to the previous one. You will temporarily loose root (until you re-root), and your phone will not lose any of its userdata. The phone, minus the bootloader, will be in about the state that it was in from the UCU1ANCE firmware, so that it is easily rooted again. The disadvantage, if you want to call it that, is that the phone will not be upgradeable through OTA updates. That can be fixed at a later date by following step 4.
Note: If there was a factory reset before, or probably after this step, you might get some strange things in your operating system since you only flashed the AP file, like a different keyboard, and a mobile data toggle in the notification which I actually liked. Also, your APNs will probably get wiped and you will have to re-enter them manually:
Name: ATT Phone (Some might have PTA in place of Phone)
APN: phone
Proxy: Not set
Port : Not set
User name: Not set
Password: Not set

MMSC: http://mmsc.mobile.att.net

Authentication type: None
APN type: default,mms,supl,hipri,fota
APN protocol: IPv4
APN roaming protocol: IPv4
Enable/disable APN: APN enabled

6. If you are looking to recover from a softbrick, but are not looking to loose your userdata, then your only need the AP_G900A file.

THE ORIGINAL VERSION AND ORIGINAL EDIT: (so the previous comments won't become confusing)
For those who've soft bricked their s5 after towel root, and who are on firmware G900AUCU2AND3, including myself, we could all use the G900AUCU2AND3 firmware, which unfortunately is not available right now to the public.
I don't have the time of day to make a full step by step guide, but here are the steps that I did to get my phone back running. It's not perfect, and does not bring the phone back exactly to how it was, but it is an emergency fix for if you need the phone right away.
1. You're going to need the firmware from this thread. Only use the first file download. The other, as well as the one from Samsung-updates and Sammobile will not work.
http://xdaforums.com/showthread.php?t=2714455
2. You'll need to extract extract the files.*
3. You are going to need Odin 3.09. 3.07 may work as well. You will need the AP_G900A file only. BL for sure will not work, and I have not tried the other 2 files yet.
4. You need to boot into recovery and do a factory reset. Then you need to boot directly into download mode, and not into the operating system.
5. You have to flash the AP_G900A file in AP, or PDA with ODIN, depends on whether it's 3.07 or 3.09. Make sure only Auto Reboot and F. Reset time are checked.
Once my phone rebooted after Odin, the operating system was downgraded back to the previous one. I lost root access, as well as gaining some other things that I do not like, like the keyboard. I also gained a mobile data toggle for some reason (Maybe I had it previously, but don't remember it). I was able to easily re-root the phone, and I also had to re-enter my APN settings, as those were also wiped which killed my mobile data connection.
Like I said, it's an emergency fix. It's not perfect. If it does work for you, your phone for now will be stuck on the previous operating system until there is a ROM to flash or a new OTA, as there is no current firmware to flash, and the current OTA will also fail because you still have the same bootloader as the one you're trying to update to.
ORIGINAL EDIT: It has now been discovered that three of the four files, AP, CP, and CSC do indeed work. You have to flash them separately one at a time; flash one, reboot, then flash the next. You will temporarily loose root, and the last one, CSC, will factory reset your phone. Also the OTA now works after flashing all three files, so we are now all good.*
Thanks to davew41 and pcidiot for doing some of the things that I initially did not have time to do. I will re-edit this post later.3
Go to this thread and scroll down to troubleshooting section download the downgrade to NCE tar and flash it in the AP slot using 3.09 you'll be fine and back to bone stock NCE
http://xdaforums.com/showthread.php?t=30211203I loaded all files minus the BL files and it worked perfectly. The first time I used just the AP file and rebooted. Seen the Keyboard was different etc, stuff the OP stated. So I factory Reset and started over Loading all files but the BL file and let Odin do its work. Upon reboot Keyboard was back Modem setting was there etc. Working great. I was also able to update back to G900AUCU2AND3 firm ware immediately upon checking.2
Make sure you download the firmware from the post you were linked too. I can confirm that the SamMobile firmware will not work on ND3 software.2
https://dl.dropboxusercontent.com/u/38127313/update.zipTwo different WiFis. It won't let me over mobile data. Do you happen to know where I can obtain the update.zip? I do know how to adb a bit.
That link will not be up for long.
You need to sideload it from stock recovery. Also, here is a page on how to sideload adb.
