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.

The easy way:

[Q] Need Urgent help !!!!

After i upgraded a friends I9500 to Official Lolipop , he complained about crashing apps, and other sutff like that , and he ask me to revert lolilpop to stock version . I do the downgrade with odin , i flashed a south african rom, which is allowed for downgrading , ( 4.2.2 i guess ) , everithing worked fine until the phone booted and see there`s null imei , baseband version , etc. After doing some researches, trying to flash other stock rom ( like 4.3 or 4.4 with no succes ) , flashing modem a few times , trying the method with efs backup ( even if i haven`t make any backup before downgrading ) , I get a fake imei and that`s all and still cant use the phone to make calls.
My Q is , how can i revert the original imei for I9500 ?? Need urgent help !
Thanks for your support.

Reflash lollipop modem/firmware and you get imei back.
Then you can use this if you want downgrade

ive seen many people complaining for loss of IMEI after downgrading

BACKUP your EFS folder as per the stickies .

Exactly, make a bacup of EFS folder- if you have root use for example this app https://play.google.com/store/apps/details?id=ma.wanam.efs&hl=pl

You can't take a proper backup without root, you can't take a EFS backup without root, so whatever hesitation you are having about rooting, well you need to get rid of it.

Im downgrade so many time and no problem with my device N9005 Im alway using TWRP format all/ cache/dakvil/data/system and go to download mode and flash normal. Never missing IMEI and another problem. If have problem. Dont worry, you flash again with file PIT and tick to re-partition. this everything you need!

I did a mistake, it is possible to move this thread on help section?
Hi all, today ASUS released the OTA but in some days the full rom will be also avaible.
I want to do a fresh install but i don't know how do this :crying:
I was a Samsung S2 Plus user and there was really easy flash something but on ZF2 with fastboot and recovery i don't know where go.
I am using full stock ROM unroot never touched. There is a SAFE way to flash a full firmware? I read that someone deleted some partition and IMEI was lost
