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?

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:
From couple of days I am facing a bit unique problem that whenever I enable my data into #GSM it shows h+ and runs 3g and after a while it auto changes into E from h+ and within a minute data network gets disabled.. And again it auto enable data and same process starts: h+ to E, E to h+ and disable / enable.. Network data gets disable enable automatically...
Maybe a provider problem
Hello and thank you for using Q/A,
did you try a factory rest. It can be a provider problem.

How you recently update your phone's firmware?
If so, Its not really an unique problem, since I am experiencing the same.
With an OTA update to I9505XXUPOL1, my data connection was not working at all.
To fix my data connection problem, I have flashed I9505XXUHPA1, which was stable connection, but only E (gsm) connection, it has disable LTE.
Sources within this forum say that I9505VJUHOK1 (south america firmware) works properly, I have not tested it yet. If some can confirm please let me or us know.
I download my firmware from the sammobile website

Hehe... I think it occured after couple of master reset?
*IIhan87 I flashed 4.4.2 firmware long time ago and the problem occured now... My baseband is XXUGNH6. And it doesn't have lollipop firmware too if it had I would have tried latest firmware to solve the data network issue: (
Hi guys, when to flash custom rom on the 900F , 3g is lost and there is no line APN settings and select CDMA or GSM, CDMA only works without a 3g .... cant understand what was happening, there was a problem after updating to OK4 tried already ... about 10 ROMs ...
So... What phone do you have? a G900F or a G900P? Remember that sometimes the custom roms for G900F are not compatible with a G900P and if you use it on Sprint you won't be able to get your phone to work correctly with CDMA, Reflash to stock OK3 on odin but before wipe data cache and stuffs... Hope it helps, it does on my G900P
I have G900P ... Until the update to OK4, everything worked
in the upper left corner instead of the Sprint ... roaming indicator is written off
