No, no, my phone boots. It works well. When I bought the phone, it on ND3. I tried modifying my SecSettings.apk and failed miserably, causing it to stick at the AT&T boot logo. I used the method in the OP to revert to NCE and I am using the phone as such. Everything is back to NCE except my bootloaders, but this is to be expected. For some reason, however, my bootloaders fail the update check when applying the ND3 update, and cause the script to go kaputt.
[AT&T Samsung Galaxy S 5] MercilessLTD:
Just out of curiosity, what would be the problem with Odin-ing the firmware package available at sammobile?

UPDATE: To answer myself, it includes the bootloader, just like the BL file in this package. Therefore it fails and would not work.

Great guide!

Out of all the guides online, yours is the only one that I tried, that actually worked, the download is awesome to have too. Thank you!
[AT&T Samsung Galaxy S 5] johnmayfieldjr:
Thanks man this is useful but I am not able to downgrade from ND3 to NCE. I have a softbrick btw, stuck in a bootloop, keep flashing the files in odin and still looping. Any ideas on fixing this?
[AT&T Samsung Galaxy S 5] FtaWolf:
Try factory reset.

At&t how about unlocking Bootloader on SM-870A ?
[AT&T Samsung Galaxy S 5] gregsarg:
As stated above....

Boot to stock recovery and wipe the device clean...

Then boot into download mode and flash the Odin package...

Although Odin should overwrite any existing data on the device...there is always the chance of leftovers hanging around in there...

Edit:...use Odin 3.09....g
[AT&T Samsung Galaxy S 5] johnmayfieldjr:
Thanks man, did this before and tried it again. Still no luck.
[AT&T Samsung Galaxy S 5] shortydoggg:
Try a factory reset first. Then only flash the AP file, then reboot. Then the CP file, then reboot. Then the CSC file, then reboot.
[AT&T Samsung Galaxy S 5] johnmayfieldjr:
Thanks for the suggestion. Gave it a shot before and tried again, also did a factory reset in between each file. Nothing seems to work, still looping. May just have to wait for a new firmware.

Downgrading a new S5

Hey guys I have read and searched all over the forum and am now so confused my head is ready to explode.

I have ordered a new AT&T S5 and I am sure it will have a kernel too new for towel root. I have read about 'downgrading' the kernel by flashing on older one with Odin and then rooting and then flashing the new kernel back.

Is this possible or am I completely misunderstanding what I have read? I really want a 5 but I have to have root so if it isn't possible some other guy here at work will get a 5 and I will keep the S4

Thanks!

i did, everything worked, now i the ota update fails at 31%. i dont know how to fix that.
[AT&T Samsung Galaxy S 5] MercilessLTD:
I had the same issue (the update consistently failed at the 32% mark). For me, turns out that the bootloader doesn't match, for reasons I'll never know.

What happens is, at the beginning of the process, it does a checksum on the existing portions it will update before it does the update. The reason for this is, all of the updates are patches, not overwrites. Therefore, if the file isn't exactly as expected, it will possibly brick your phone.

My phone was failing on the bootloader. Everything else matched, but the bootloader was different, despite it saying it is the NCE bootloader. I rolled the dice and commented out the check as well as the bootloader update-patch and it worked. So technically, my phone is ND3 all the way, except on an NCE bootloader. I run Dynamic Kat 2.0 via SafeStrap with no issues.

Trying to downgrade from 4.4.4 OA1

I see this post started in June 2014. Fast forward to March 2015. I had my GS5 running, rooted on 4.4.2 with no "Custom status" flag.

I get wind that 4.4.4 is available and it now supports AT&T's "HD Voice" which uses 4GLTE.

So, I re-enabled all the disabled apps, etc that I disabled with ROOT and fully unrooted the phone. Then I allowed the OTA to happen. The result was less than desired. The custom status flag came on and now when I try to forward my phone, I get an error "network or sim card error".

To fix this my idea is to totally downgrade to 4.4.2. Hopefully that will allow my call forwarding to work again and perhaps re-try the OTA 4.4.4 upgrade. If I get that to work, I will try to root again.

1) Does this seem like a reasonable approach and can anyone find a flaw in this?

2) Should I try to reload the BL because I already had the phone on 4.4.4 AO1?

Thanks in advance.
[AT&T Samsung Galaxy S 5] s8freak:
No problem downgrading I've done it a couple times already.
[AT&T Samsung Galaxy S 5] scmagee:
:)

So, should I try the BL? Do you think it the BL downgrade will fail? My current BL is now AO1.

If I don't or can't reload the BL, will it be a problem having the BL at AO1 and then AP,CSC, and CP at 4.4.2?

Do you think this will get rid of the custom Status flag/icon?
[AT&T Samsung Galaxy S 5] s8freak:
Don't flash BL it'll fail.

If all you want to do is get rid of the custom unlocked pad lock then download triangle away 3.26 and install then follow the prompts

OP doesn't say S5 is supported but I've used it on every Galaxy S since the S2 upto and including the S5

http://xdaforums.com/showthread.php?t=1494114
[AT&T Samsung Galaxy S 5] scmagee:
Thank you so much. Triangle away worked I no longer see the "open lock" on start up and the download screen says official. Weird though when you go into the menus, under status, it still says custom there. I think that indication comes from a more extensive scan way after the bootloader is done. There is still something that is off. More of a curiosity then anything. In any case, you saved me a ton of time. Thanks

How did you get it to work? Mine's doing the exact same thing. ODIN from 4.4.4, boots to Samsung, goes black and blue LED stays on. I've flashed, reflashed, cleared factory settings, etc. I've flashed several phones dozens of times, and I can't seem to get passed this bootloop

Full Disclosure

stock 4.4.4

flashed AP, CP, CSC in ODIN 3.07 and 3.09 and it PASSED (all for ANCE and have used these files before so I know they're good)

phone reboots, starts the Samsung boot animation and freezes about halfway through

screen goes black and blue LED stays lit

recovery shows ANCE and KNOX is still intact. Everything LOOKS like it's working, but it keeps looping/freezing

I'm not sure but for some reason flashing separately coming from OA1 4.4.4 results in the bootloop

downgrade to NCE and flash NG3 and OA1 zip files

Background:

I have a ATT Samsung Galaxy S5. I recently switched to T-mobile and has been using my S5 of Tmobile.

The S5 always had low volume from ear piece. Its was manageable and some time I will have to ask other party to repeat.

I had rooted my phone and modified media_params.xml but without much success. All boltware was frozen with titanium.

I was running G900AUCU2AND3.

Last week I decided to upgrade to latest ROM version.

1 - First, unfroze all the bloat-ware and ATT update app.

2 - Phone immediately says and download update of 142MB size.

3 - Phone reboots to install the update. Install fails at 28%.

4 - I tried install couple of times and every time it fails at 28%.

5 - I did a factory reset and tried the upgrade.

6 - Same story, downloads 142MB file and upgrade fails at 28%.

7 - I unroot the phone using SuperSU. Update still fails.

8 - I was thinking there is some serious problem. Many people report this issue on ATT forums.

https://forums.att.com/t5/Samsung-Discussion-Support/Software-Update-Failed/td-p/4058678

https://forums.att.com/t5/Samsung-D...5-SM-G900a-software-update-Error/td-p/4058052

9 - Finally, I downgrade to G900AUCU1ANCE following steps in http://xdaforums.com/showthread.php?t=2785185

I flashed all 3 files as per step 4 in OP.

The bootloader remains at ND3. Baseband was downgraded to NCE. See screehshot.

10 - Tried OTA again. Update fails at 28%.

11 - Further searching on xda, http://xdaforums.com/att-galaxy-s5/general/how-to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120

I found NCE to NG3 OTA zip file (see Troubleshooting: section in OP). I download G900A_NCE_to_NG3_OTA.zip and tried to flash it from recovery.

12 - Update/Flash fails. But this time it gives an error message "E:Error in /tmp/sideload/package.zip (Status 7)". See screenshot attached.

13 - Back on xda, I find someone with same issue. Read post around http://xdaforums.com/showpost.php?p=55135164&postcount=17

14 - I then followed steps in http://xdaforums.com/att-galaxy-s5/general/g900and3tong3keeprootota-zip-t2862299

Notes: 3 to flash G900A_Downgrade_to_NCE.tar using ODIN. Bootloader remains at ND3 and baseband was downgraded to NCE.

15- Another try flashing G900A_NCE_to_NG3_OTA.zip from receovery. Viola, success. Bootloader and baseband changed to NG3.

16 - Tried flashing G900A_NG3_to_OA1_OTA.zip and that too went fine. Bootloader and baseband changed to OA1.

17 - Steps 15 and 16 run as per Troubleshooting: section in http://xdaforums.com/att-galaxy-s5/general/how-to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120

I didn't have patience for another OTA download. Hence flashed OTA zip files.

Final result:

1. My ATT S5 was running OA1 firmware.

2. The ear piece went extremely low voice. Not audible at all. Since it was under warranty, I decided to head to Samsung for repair.

Soft bricked galaxy s5 ATT G900A haaalp

Hello, so I recently got this AT&T S5 and updated to lollipop 2 weeks ago and hated it, thus I tried downgrading

and eventually soft bricked it. I have read tons and tons of sites, tried this thread and all other others linked from this one.

When flashing the stock fw throught the AP, I ALWAYS get fail. I have tried thousands of other files and same result.

HOWEVER, only thing that seems to work perfect through odin is the CL file. I have problems with the AP and CSP file.

Before flashing the CL files I could NEVER get into recovery mode, but only download mode.

Is there anyway of flashing through the recovery via sd card? Since Odin fails on my always?

By this I mean i have tried 3 different pcs, different cables, usb 2.0s and 3.0 ports, 3 different versions of odin and same fail.

[AT&T Samsung Galaxy S 5] s8freak:
No you're right there's only the four files i guess my point being flashing the latest firmware using Odin will result in a fresh device but no root and it seemed to me that was the only solution.

I've taken my devices as a last resort to the ATT warranty store and as long as it was in download mode they've flashed the latest firmware without even asking or checking for root.

Maybe they were just being reasonable.

To avoid that and having a working device would be to Odin the four files and forgo root.

Maybe I misunderstood the problem.

[AT&T Samsung Galaxy S 5] 123guy:
soft-bricked S5 while trying to Unroot with Odin G900AUCU1ANCE AP+CP+CSC

Hi all.

Bought a used AT&T Galaxy S5

I found out the phone was rooted after the the AT&T over-the-air updates kept failing.

I decided to try unroot.

The Android version was 4.4.2, but i neglected to check if it was the original G900AUCU1ANCE as opposed to the newer G900AUCU2AND3

I tried the common Odin method with just the AP file from sammobile.com (which is the older G900AUCU1ANCE) - Odin failed

Then I tried Odin with AP+CP+CSC from files, after googling this thread http://xdaforums.com/showthread.php?t=2785363 - Odin passed but the phone is SOFT-BRICKED

S5 freezes while booting at the colorful Samsung logo, then goes dark except for a blue LED.

However, I can still Download-boot and Recovery-boot.

I then googled up that there are different versions of 4.4.2 http://www.galaxys5update.com/galaxy-s5-stock-firmware/ and that they don't play well together.

I also tried to side-load the AT&T over the air update mentioned by Emily J Fox in the comments of this thread: http://www.galaxys5update.com/unbri...00a-soft-brick-fix-restore-to-stock-firmware/ by loading the ZIP file on an SD card, but that route causes errors and quits.

below is a dump of the download-boot screen:

ODIN MODE

PRODUCT NAME: SM-G900A

SYSTEM STATUS: Official

REACTIVATION LOCK(KK): OFF

KNOX WARRANTY VOID: 0x0

QUALCOMM SECUREBOOT: ENABLE (CSB)

RP SWREV: S1, T1, R1, A2, P1

Any ideas?

Thanks
