[Q] 4G not working after 4.3 update

Hello everyone,
I have Galaxy S4 I9505 that is unbranded and unlocked, updated with the latest firmware via Kies3. Stock ROM, Knox 0x0.
My firmware info:
PDA: I9505XXUEMKF
CSC: I9505BTUEMK5
MODEM: I9505XXUEMKF
(I checked on sammobile and its UK BTU firmware)
I am from Croatia using T-mobile as a carrier. Problem first appeared right after the first 4.3 update was released via Kies3.
The problem is that when I select LTE in Network mode options it doesn't connect to 4G, the icon only shows H+ in a 4G area. If I leave it running in LTE mode, after a while the mobile data will shut down, signal will drop (like it resets) and after a few moments it will work again. My mail or whatsapp messages for example will arrive 10 - 30 min later. This will repeat over and over until I turn it off in Network mode and select WCDMA/GSM only. Everything was working fine prior 4.3 update.
Also I hope there is a solution that doesn't include flashing custom modem files or anything that voids my phone warranty.
Thank you,
Skyward
Anyone??

[Q] No wifi after flashing firmware with odin

My phone had mobile network signal problem like weak signal,emergency call only and not registered to network.I tried to flash different modems for the issue but it didn't resolve the problem. So i decided to flash complete firmware with Odin3 v3.04 now the mobile network seems to be working fine but i don't have any wifi bcoz the phone is not turning on the wifi at all.
I have flashed a stock 4.2.2 of France region i9505XXUBMGA and my device actual firmware was of Hong Kong region I9505ZHUAME1 can that be the cause of problem.One thing else that i have noticed in setting about phone that the baseband is still being showed of the Hongkong region i9505ZHUBMF4 that i flashed before flashing the stock France region 4.4.2.
