update 5.0 dilema

[androidfine16]

hey guys
I recently decided to opt in to flashing 5.0 rom on my device, but ive read somwhere (http://forum.xda-developers.com/tmobile-galaxy-s5/general/warning-flashing-bootloader-modem-t3037034) that people are having trouble restoring backed up roms and even going back to NK2 with full odin wipe. I have also read that flashing a custom 5.0 kernel will resolve this issue. Is that true, i want to know by someone with expirience. And also can i flash custom roms while on 5.0 bootloader if i load it with a custom kernel.
IAM NOT planning on taking the OTA update but rather ViSiON-X Rom http://forum.xda-developers.com/showthread.php?t=2797336.
My main concern is being able to flash roms/restoring/backing up, specifically custom roms not touchwiz based and Kitkat.

THANKS IN ADVANCE

I updated via Odin tar file.

About restoring from a nandroid custom recovery backup:
I think/thought I mentioned this in that first thread you linked, but, you cannot in any way restore an old backup onto a new version of android irregardless the device or recovery. Say the system apk, settings apk uses a file named xyz.dat in KitKat, it saves that file to your /data directory. You now go ahead and flash Lollipop which now that same system apk, the settings apk uses a file named yzx.dat, you go and restore your backup restoring the file xyz.dat. Now the settings apk which is a system apk, cannot find this file and runs into a bootloop because not finding the file should never happen but since you went behind its back to remove that file, you confused it majorly.

I use Titanium Backup to restore my apps, best money ever spent.

I personally went back to KitKat, cause, well, I missed xposed more than i thought i would lol. Everything just worked the way I wanted it to with xposed.

I did have to Odin flash a KitKat based ROM in order for it to work though. After that, I restored my full nandroid backup and everything is working again.

My recommendations to you:
1. Take a FULL backup using TWRP or other custom recovery, this includes backing up your system, data, and boot.
2. Flash the Lollipop update using Odin.
3. DO NOT WIPE DATA
4. Reboot.
You should see "android is upgrading" and have a Lollipop build with all your apps still there. i got a few force closes so I ended up wiping my data, but those apps that forced closed were all root apps that were looking for system files that didn't exist anymore.

Yeah I avoided lollipop all together. People seem to be having too many problems with it.I installed NK2 via Odin and now rooted/exposed. Runs smooth and I can flash other Roms.

But I do have this one issue. My auto rotation rodent seem to be working I tried everything I can think of. At first boot it works for 10 minutes or 5 sometimes. Than it shuts down completely. Accelerometer isn't working either. No temple run movement or asphalt 8 (sucks). I did sensor firmwate update and ran samsung diagnostic. The sensor seem to be at 0,0 on x and y axis. At first boot they work fine though. Any help please. I even tried different kernel and software Roms to no Vail. And I don't think it's hardware cause it works for brief moments.

I let the lollipop update happen.. Used the last day and everything seems fine but I can't use Screen mirroring which I use alot.. anyway I downloaded the stock 4.4.2 md5 and odin completely successfully writes it and after it reboots it is stuck at the Tmobile 4gLTE bootscreen.. I've rebooted it and waited a long time.. as well as rewriting. Guess I'll have to download the stock lollipop tar and hope it boots

The 4.4.2 .tar is a "non-wipe" .tar. You need to go into stock recovery and do a factory data reset after flashing.

Did the trick, thanks!

Does downgrading like this trips Knox?
Thanks

I downgraded my wife's phone using the official 4.4.2 firmware from sammobile, and it did NOT trip knox.
