Hi there, I would like to know if other people are having signal problems after the MM update. I am on Tmobile on a AT&T Unlocked Priv that WAS working perfect (signal strength wise) when it was on Lollipop. Since I upgraded by OTA to MM using a friends Simcard my signal is a mess. It cycle between LTE , 4G, 3G, EDGE all the way to GSM (G). And when I hit the road it stay in EDGE most of the time. That didn't happen in Lollipop and have never happened in my Nexus 6 and Nexus 6P. So is no TMO signal, is something that AT&T or Blackberry change on the modem firmware.
I tried to flash the old modem (lollipop) but it won't boot and told me the data was encrypted and corrupted and needed to wipe my phone. I flashed back the MM modem and booted. I flashed the TMo modem and I don't think it is sticked or maybe is it just the same one. Can you reply with your baseband numbers. Mine is MPSS.BO.2.6.2.c2-0007-M8994FAAAANAZM-1.55185.2
Any help will be very appreciated.

I have downgraded and upgraded a bunch on many different firmware. i flashed back stock on the latest firmware now, and i get fluttering between hspa+ and LTE. My apn is correct. What else could this be?
I am having signal issues with the n9100 (china mobile). Currently I am in Canada on Rogers network. I have rooted the phone and currently using a custom Rom (Aurora). The firmware is on 5.1.1 and baseband is on the latest. I do get 4G signal but it gets weak when I am inside my house and usually is in Edge mode. The signal was decent when I was in China. I am sure its a modem issue, but is it possible to install a rogers modem onto this without bricking (probably lose dual sim but thats ok)? If not, is there a fix? Can I force my phone to use a certain frequency/band that Rogers uses and see if that helps?
Hey guys, I have a verizon galaxy s7 edge and a verizon galaxy s7. Both are on QF3 U-firmware. I am using the phones on Metropcs but the signal is weak. I'm heard that if i flash tmobile modem on the phones. I will have better signal. Is that right?
Where can I download the modem and how to flash them?
Can I use modem for S7E on S7?
After flashing the modem, will the phone receive OTA update?
Thank You!
Well I am on Tmobile and also using the 930U firmware. When I flashed the Tmobile modem I noticed I had way more bars, however, I went into settings > about > I think sim status and the actual signal # is the same. Dbm or whatever.. So i really think in my case the Tmobile modem was just a graphic chagne, and not really a better signal.
Anyways while running the 930u firmware and Tmobile modem I would not receive OTA updates - I had to flash them manually.
The way to get the modem you will have to download the latest tmobile firmware for your phone (SM-G935T - 935 since you have the edge). Then unzip the package and you want to flash the CP with odin.
If you flash the T-Mobile modem you will actually get carrier aggregation enabled, something I don't notice under the U firmware. Oh and might also have priority on T-Mobile bands .

Hey guys, i've read a lot here and i think my problem is kind of mysterious.
I got an A2005 with stock Rom and LTE was working only on Band7. In germany i need Band20, which the A2005 originally doesn't support.
Then i flashed RR Rom and tried to unlock additional Bands as mentioned in several Threads.
Now i can't get any LTE Signal.
This is what i already did:
deleted the whole phone, flashed stock oxygen OS 3.6.0. No lte.
What can i do now?
I've just updated to 3.6.0 and i no longer get LTE on my signal meter. I get 4G all the time but I am on a network that supports superfast LTE so I have no idea if I'm actually getting those speeds still.
I did see a thread about band unlocking but I don't wanna risk killing my daily driver.

Hello. I have unlocked Verizon V20 VS995 and I am in Europe. In the urban areas phone works fine with all frequencies, also 4G B3 and B20 frequency, but when I go just outside town it looses network. Any sugestions?
CDMA LGV20 will suffer with those issues in Europe. So just switching to a native LTE/GSM device is the only way...
But I can't understand why the sognal is so weak when phone supports all the frequencies in my country. I even changed antennas (plastic bumpers) but still the same result.
Simple explanation - it is not a HW issue - the root cause is combination of your modem firmware and stock ROM you are using as the LTE/GSM band usage is set to be with lower priority and the modem constantly searches for the CDMA signal firstly...
So, is there anything to fix this? Maybe flash another rom or modem, if I find somehow to root stock Oreo.
If you are in VS995 really (and please check the sticker indication under your battery for that it should state VS995 only without Sat the end) you can roll back to Nougat via kdz flash and unlock the bootloader via DirtySanta, flash custom recovery and flash afterwards AOSP/LOS based roms.
I think I have VS995 because before ota upgrade to Oreo I have installed few KDZ's from the link without any problem. Can you tell me how can I check ARB version of Oreo?
All Verizon ROMS including Oreo are ARB00
Also you might try flashing Oreo Alpha Omega Hybrid ROM firstly and if not happy than try RR roms...
Tried Alpha Omega ans Lineage 15.1 and the situation is the same. Poor signal strenght.
