I have a G920F at the minute which suffers from poor reception. Now a new modem OF8 have been released for the G920I that improves the poor signal issue. Upon checking out the 2 phones the G920I modem has all the bands that I need even though I have a G920F. LTE 1800/2300, 3g 2100, 2g 900/1800. So Im wondering is it safe to flash the G920I modem.
Do not flash ROMs other than made specifically for your G920F.

I am getting poor AT&T LTE reception on my 920F despite having all the bands and freqs required for ATT. Is it possible to flash the latest AT&T modem on my unrooted 920F?
Hello guys!
I live in the states and I get weak cellular signals most of the time. I have the exynos variant because i heard it has better ram management and battery. I have flashed the bootloader and modem BL_G930FXXU1BPIF and CP_G930FXXU1BPHJ and installed superman rom on it. I also flashed the csc for TMB because i use tmobile. So the problem is that I dont get good lte speed and the cellular signal is always low. Can i flash G930T modem on the exynos version or it will cause problem because G930T is the snapdragon variant?
Any help is appreciated!

I think it is only the bootloader that you have to be careful with. Try the modem - you can always ODIN back the CP above if you have issues.
PS - try this new CP/modem module - it has the new TMo LTE-A in it - over doubled my download speeds:

Come to think of it the modem may also be hardware specific, so the qualcom one will not go on your 930F.
I would search the threads here and in the US TMo threads to see which phone firmwares (by country) are working best over here on 930F/935F(I have seen some when I was considering getting a 935F or FD), and then download the full firmware and extract the CP from the one that works good and ODIN it.

Maybe you need to install the whole firmware.

I just flashed the modem and still the same result. Maybe coverage here in lubbock, tx is just bad.
Hi!
I am running a rooted stock firmware and TWRP on my S6 G920F but I am struggling with the quality of the signal (phones on the same network do have a better quality of signal even when we are in the same room and people are having difficulties to call me etc...) so I am thinking about reflashing the modem with another firmware...
Could anyone point me to a place where I could find twrp flashable modems for my s6, please?
Thanks!
I bought 2nd SK Telecom unit (930S), which has same SoC as 930F. Is it possible to flash 930F modem to 930S? I get this issues regarding mobile network in LTE doesn't work well, I have to lock it to WCDMA in order to make network run again. I suspect this as modem issues, but is it? Or is this OS problem? Tried 3 carriers, problem persists.
While they are the same SoC, there are some differences that will make flashing G930F over G930S result in bootlooping.
I assume you're not in South Korea?
The firmware will be configuring for Korean carrier / networks. Your best bet would be flashing TWRP, then using this to change your device to your carriers CSC https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957

It could be the stock ROM on there (with sk apps). When I bought mine I immediately flashed TWRP, NAND backup and flashed a custom TW ROM and had zero network issues. I never bothered seeing if the stock ROM was worth using. I'm using BlackPearl with zero problems with network or otherwise on AT&T.
I should clarify many custom ROM's work on goth 930F and 930S, but stock 930F images will bootloop a 930S.
hello, im using g930s too with g930s stock bootloader and baseband/modem. but with hyper alvi 4.1 rom. still got problem in 4G mobile network signal. should i try to change csc or modem file? i think the csc was from wrong country, could that be the culprit? thanks guys
Hi. A friend brought me an S7 (AT&T variant) with the following problems.
Network doesn't work over 2g (only edge connection)
The firmware version was incorrect (showing SM-G930F)
We are in Argentina*
I've flashed a oreo firmware for g930u variant with G930UUEU4CRG2 baseband
Thw phone works well, but the network problem persist, only have 2g (edge) internet.
Calls and sms works, apn settings are correct
Any idea?
Thanks for read

Then why 2g works and 3g no? Both use 850/1900mhz (B2 and B5 bands)
