please give me solution ??

Take a 4.4.2 package unpack it and remove bootloaders, then repack and test.
You can opposedly to SGY firmwares (s5360) open S4 firmwares with Winrar / 7-Zip.

User who say that are user who don't even care about their country code nor their CSC
If your CSC is XEF then you have to flash a non-knox 4.4.2 XEF ROM, if wifi/IMEI is null it's most likely a MODEM mismatch.
Just reflash the modem by using Odin3's CP section :good:
EDIT :
Or you may just try Mobile Odin Pro, for a buck it downgrades the phone a simple way.

I first rooted and installed SUPERSU on my device with lollipop 5.0.1 to get x mode games. Since xmodgames doesn't support lollipop currently I decided to downgrade my Samsung GT-I9500 from lollipop 5.0.1 to Kit Kat via ODIN after doing a complete wipe via philz_touch_6.12.8-i9500.tar but after the install My mobile had null imei. I was able to successfully root the device and install SUPERSU and Xmodgames also worked fine but without any mobile network due to NULL Imei.
I tried all forums some had software to remove the null state and some had service code etc, but nothing worked and a techie told me that this can now be restored only through some box available only with professionals and asked me a very high fee almost 30% cost of the device.
I finally figured it out and restored my phone back to lollipop 5.0.1 after doing a wipe by PHILZ (without root selected) and my phone was back to its original state.
Hope this helps.

Hi Mike, search the forums before asking any questions. Search google. Don't expect everyone to do your job for you. Post your threads in the right section. This question has been asked and answered a million times and you'd know this if you took 5 minutes to search a little bit.
Here's your answer https://www.reddit.com/r/galaxys5/comments/2ubsbs/guide_rooted_android_50_for_the_international/

out of curiosity, why dont you want to trip knox flag
"This question has been asked a million times and you'd know this if you took 5 minutes of your precious time to search a little bit."

What model do you have? Find out in phone settings in system / phone info. Sm-g900a has locked bootloader. I think verizon's phone also has a locked bootloader.
The link I gave you shows how to upgrade to lollipop, root it and keep knox 0x0.
Isn't that what you're looking for?

my bad, you did. 900f has an unlocked bootloader. when you upgrade to stock lollipop through OTA or Kies (or odin) it already includes bootloader and modem. When you do it the way described in that reddit link you flash the lollipop firmware, modem and bootloader separately. Apparently that method of updating needs it to be done so.
Honestly I have Knox 0x1 so I never cared for those methods, btw if you live in Germany then there's no need to care about Knox. In EU we're allowed to flash whatever we want and the guarantee stays intact even if you have Knox 0x1
ps. yes =p

Honestly, I don't know. That reddit link I gave you, I haven't read the guide myself. I just skimmed though it to be sure it was real but I don't know the details of it. Yes all G900Fs have an unlocked bootloader. :good:

Do you mean ota stock firmware notification? If yes then you will have it if Knox is still 0x0 if Knox however is 0x1 you will no longer be able to update via ota.
If you want to upgrade from KitKat to lollipop you must wipe data from recovery to avoid any issues. It is also not recommended by me to use titanium backup to restore apps because some might not be compatible with lollipop yet or some of the app data made for KitKat may have a conflict with lollipop system, however lots of apps have compatibility with lollipop and there is a chance you will have no issues at all when using titanium backup. Even if I said I don't recommend restoring data after such a major upgrade I do recommend having a backup whether it's with titanium backup or nandroid etc because you're able to restore apps one by one and make sure that what you restore won't be problematic.
Edit - if you update with flashfire app, there is an option to keep root when flashing from rooted KitKat to lollipop and users have reported that that feature does work for them (I personally haven't tried it).

[Q] Can I restore 4.3 nandroid backup while on 5.0?

Hello,
I'm going to buy Note 3 N9005 (Poland) with upgraded android to lollipop 5.0, because noone has factory default here. Everyone getting phone out of the box and after first boot update info appear so they click it. Geez! Anyway... if i get such phone can i get nandroid backup of 4.3 for matching model from someone else and restore it not worrying about downgrade lock? Maybe with repartition option turned on with odin? If yes please post a link to your nandroid backup for N9005 XEO or any other with polish language. If noone has such backup could be any firmware for N9005 with US English.
I'm going to try downgrade like "cristityy" does, but if it fail I need to be sure I can make it other way. Can anyone confirm, since 2011yr, if this method works? I did such things before with my S2, Ace, Ace 2, Young with success. Some tries ended with bootloop but those have no lock so there were always a way out.

Nope

Because a NAND backup restore will not touch the bootloader. Only kernel if that was backed up

Need help with rooting I9500XXUHOG2

Hey there guys....I have a real annoying problem....I cannot find the right rooting file..... my device baseband is I9500XXUHOG2
AND IT'S A REAL PAIN IN THE NECK TO FIND IT BECAUSE IT'S NOT THERE!!!!!
please can anyone help...I tried a lot of i9500 files but with no use...and I found myself unable to unroot and not having the root permission. ..so I endup recovering it with Samsung program (I don't remember the program's name but it's not kies)
Please I need help ASAP!
and another problem....after a false rooting I endup recovering the original stock rim via Samsung and it takes 6 FREAKING HOURS TO FINISH!
Is there a faster way ...like backing up stock rom (my rom of course because it's not avalable) because it's an EGYPTIAN.

Hey there,
Have you tried CF-Auto-Root?
To backup your entire rom you will need a custom recovery. I recommend TWRP.
And you should be able to find pretty much any stock roms on sammobile.com.
Good luck.

Thanks for replying fast...but there is a problem
I didn't find the one I need... that might cause a problem ,
Scince I am still a newbie when it comes to these stuff
I don't risk too much because I don't have a backup plan
Like the software on Sammobile.Com is not the one
I have... I heard about the 1 click root like king or lingo root
A friend of mine tried it but it's Chinese so it's not
Something you should trust... but it's the ease way right?
Perhaps too easy to be secured.
Now I am start to wish that I bought a i9505 ... at lease it's more famous and have more support than my phone.

CF-Auto-Root is your best option. There is no real 1-click root method.
