I need some help....I was on the last version of Knox Raid and decided to flash to Dynamic Kat. I installed the latest version of SafeStrap and tried to get into recover mode after re-boot...no splash screen...then I remember there was a folder called "togetsafestrap" where I went into Odin and installed the BL and AP files there...it installed successfully and now I get a boot loop. I am still able to get into download mode but tried flashing to stock version MI9 using Odin...but it failed. Help?
Ok...I got everything fixed.
Went here and followed the steps.

Background: I had updated to OA1 4.4.4 on s5 900A. I had some issues, so I decided to downgrade as described in the upgrade thread here: http://forum.xda-developers.com/att...to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120.
I would downgrade by flashing in odin the G900A_Downgrade_to_NCE.tar, as well as the G900A_ND3_Stock_Kernel, rerooting with towelroot, installing safestrap, and flashing one of the many 4.4.2 roms.
However, upon boot all of the 4.4.2 roms would be laggy, I would sometimes get a green/pixilated effect on the lockscreen when unlocking, and battery life would be sub par. I came across this app on play store:https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en , and even though I had downgraded the kernel, the bootloader read as OA1, even after flashing in Odin the ND3 stock kernel.
I believed that was causing the issues I was having, and was under the impression that the bootloader could not be downgraded. In a fit of frustration I did the following, and fixed the problem!
Solution:
This is not a step by step, but a rough approximation of what I did, if you need more detail, just ask.
1. I downloaded and put on my SD card G900A_NCE_to_NG3_OTA.zip https://www.androidfilehost.com/?fid=95916177934525665
2. In odin 3.09 I flashed G900A_Downgrade_to_NCE.tar https://www.androidfilehost.com/?fid=23622183712464416,
3. Also in the AP slot I flashed G900A_ND3_Stock_Kernel https://www.androidfilehost.com/?fid=23622183712464356
3. My phone was unrooted at this time. I let it boot up, downloaded the Phone INFO ★Samsung★ to the phone from the playstore, opened and my bootloader remained OA1. The camera was normal, and the boot was slow, so I was where I was many times before.
4. I shut down the phone, I rebooted holding volume up, power and start until I got to the standard, built in samsung recovery.
5. I located my download of G900A_NCE_to_NG3_OTA.zip, and flashed it via the samsung recovery. It took about 5 minutes.
6. The phone rebooted, and the phone info app said I had and NG3 baseband! It had downgraded! However, towel root was not compatible.
7. I flashed in odin G900A_ND3_Stock_Kernel again. Now towelroot rooted the phone. I installed busybox and superuser from the playstore, then safestrap again.
Now I can flash any of the 4.4.2 roms, none of the slowbooting, stuttering lockscreen or battery issues seem to be present, and Phone INFO ★Samsung★ has my baseband and bootloader as NG3.
All credit goes to muniz_ri, these are all his tools! I just stumbled across this method and thought others might benefit.
I can confirm this.
I was on OA1 after flashing OA1 OTA zip from recovery.
Later, I downgraded by flashing G900A_Downgrade_to_NCE.tar. Bootloader after this was OA1.
Flashed G900A_NCE_to_NG3_OTA.zip from recovery. Bootloader and baseband changed to NG3.
Bootloader and Baseband version was verified using 'phone info' app from play store.

I think it can be flashed only from stock ROM. This is stock OTA.

Likewise, just did it, I found with me, the OTA zip file would not install with the ND3 kernel installed. So I did the original odin downgrade to NCE, booted, then the OTA zip file, booted, Then the ND3 kernel Tar file in odin. Worked .Good luck:good:
so the nce to ng3 downgrade goes in the ap or BL?

NCE. to NG3. OTA zip is done in original recovery by pressing power + volume up + home key. Then install update from Sd external.

was on Muniz 5.0, downgraded to xtreme dynamic kitkat. Still had oa1 bootloader, and was laggin really bad on boot.
Flashed this in stock recovery (wipes data part ) and reloaded my apps.
All seems to be well, without the need to go back to stock in between.
Thank you - this totally worked for me and got rid of the lag in my 4.4.2 ROM (XDK) as I had taken the upgrade to 4.4.4 way back when!
Hi,
do you do step 2 & 3 at the same time?
which field in Odin do you put the .tar file?
Thanks,
h

I'm not sure. Sounds like the reactivation was locked before you downgraded. I'm not sure how to fix that.
Hello, I wanted to install the new android update from AT&T however I couldn't since my phone was rooted. I attempted to unroot by flashing a stock ROM via Odin 3.10 the flash was successful but now it won't boot past the samsung logo. The screen goes black and the blue LED stays lit at the top.
I am able to get into download mode and recovery mode. I've tried wiping cache and factory reset. I've tried re-flashing and it still gets stuck. I'm wondering if there's any way I can just flash a custom android 5.0 rom since it doesn't seem to want to go back to stock. I've read a few guides but they all require safestrap and I can't put that on my phone.
I flash the AP, CSC, and CP with no BL and it still won't work.
Flashed the downgrade to NCE, worked perfectly.
So here is my issue, I rooted my G900A and was running the 100% stock rooted NG3 ROM by Muniz. Few days back, I woke up to find some error on my phone it crashed. So I Odin the NG3 rooted back but and it installed fine but when it booted up the ROM it had the factory mode enabled.
So, I went back to ANCE using the downgrade to NCE and even installing the complete stock firmware. It will work fine on NCE firmware, no factory mode and everything works. But as soon as I install NG3 or any other version it will boot up in factory mode and I'm unable to get out of factory mode. Data will not work either.
Would request someone to guide me to get this sorted out.
Thanks
I have a S5 Active that was rooted on 5.0 and I tried to unroot through SU and factory restore. Now im stuck at the at&t logo. I've downloaded just about every file and tried upgrading to 5.1.1 downgrading and nothing works. I know this is a long shot but is there anything i can do?
edit- tried flashing bootloader MD5 but odin keeps failing. Recovery says LRX21T.G870AUCU1BOC5

When that happened to me, I used muniz's methods to fix my G870A. Here's the link:
http://www.droidviews.com/update-att-galaxy-s5-active-to-lollipop-root-it-and-enable-wifi-tethering/
Before doing anything, try flashing the bootloader MD5 file using Odin, that could be the problem. If that doesn't work,go ahead and download the STOCK firmware for the G870A and flash it. This will take you back to 4.4.2 KK, but you can easily use muniz's method after that to get either rooted or unrooted Lollipop. Good luck!
