[Q] Modem Question.

Good day to all!, Yestarday i purchace a note 3 n900 and the firt thing that i did was to flash a kitkat rom, i live in central america and i flashed a indian rom, everything is working fine but the 3g, its not stable at all, sometimes will work normaly for a few seconds and after that it wont work, its constantly changeing from 3g to H+ and it will drain the battery really fast, i change the setting to work on EDGE and it will work correctly, slow but fine.
now i was checking over the internet and i find that the modem on a firmware can cause problems with the signal, now mi question, can i flash a modem from a 4.3 firmware to a 4.4 firmware?

[Q] weak or no signal when selected "WCDMA ONLY" G900H india

Hi folks.
I recently bought a refurbished S5 G900H , INDIA
it came with pre-installed kitkat 4.4.2, but without using anything on the mobile i flashed a custom rom .
everything was fine until i discovered that there is a problem with the network .
whenever i try to switch network to WCDMA only i get a notification stating "NO SERVICE".
GSM mode works perfectly fine , i can make calls and use internet but with a slow speed,
the same SIM works absolutely fine with other phone with same network setting at the same location .
so i tried flashing all the stock FIRMWARE available for G900H INDIA from www.sammobile.com . but the issue is stll the same .
also tried flashing different modem available but no help .
some time i get a very weak 3G or H+ network but that too in a ground or open space but not in my home .
i have tried all the SIM from carriers available but the issue is still the same .
i can check my IMEI and baseband .
what else i can do ??
PLEASE HELP ?/:crying:

I am kamran from Pakistan I have issues on my s3 neo ( dual sim) not registered on network issue only in 3g mode but working fine in 2g mode.it is rooted and twrp installed. It searches 3g available networks and takes time after searching when I try to register network it doesn't register .I have flashed it many times and also changed IMEI but same issue so help any expert

Any one expert

Just flash the stock ROM again. That will probably solve your problem.
If it doesn't, try to get a new SIM card, because the SIM can be broken.
Hope I was helpful

Problem with LTE connection after flashing a custom Rom.

Hi guys,
I flashed custom rom (Pixel Experience) and everything works very well and stable.
However, I have one problem with this Rom, LTE doesn't work at all (only 3G/HSPA+).
I tried to flash soft again without success. I also tried to upload FireHound Rom also lack of LTE.
Even when I try to force it by a command *#*#4636#*#* there is no signal, though I'm in LTE range.
On the stock Rom I had no problem with LTE.
Does anyone have a similar problem?
How can I fix it?
Thank you so much for help guys.

Check your apn settings & set your prefered network on 4g or LTE
