I need help please SM-935t - Samsung Galaxy S7 Edge Questions and Answers

I have attempted to root my phone, and it has succeeded but i noticed that after root there was huge lags and there was an annoying notification from samsung saying that my phone was rooted .so what i did was flashed stock rom but i accidentally flashed a downgraded version of the fimware that was on my phone ...so my phone went into a soft brick...so i quickly download the latest version of my phones fimware that was available and flashed it on odin.and that was problem fixed and now the Problem is my signal in the status bar only shows 4G or sometimes 4g+ and never LTE, which I have gotten before. I'm also getting H+, and H, as well as 3G, which I never got before. When I had LTE it was a significantly faster than any of the others H+, H, 3G, E.
I downloaded the firmware from Sammobile, and I'm 100% sure I used the G935T firmware. If you know of a better place to download firmware, or an official site that'd be great.
Anyone have any idea on how to fix these? Thanks.

Data Drops after Flash 12B Modem

Wondering help on this..I had flashed the 12B Modem while on the latest Verizon Unofficial CM11 Rom, But i experience lots of data drop. I flashed 12A but experience the same..So I jump back to 11A Modem, still having data drop constantly where I cant make calls or anything. Any suggestions? Hoping this can straighten out without me having to revert to stock rom, Plus I'm with T-Mobile on this Verizon G2.
Never had this issue til I flash modem to begin with. Only did so too see if my T-Mobile would get better coverage while on a Verizon G2..
Any suggestion or help would be gladly appreciated.
u dont have nandroid of previous CM11 prior to flash new modem?
I have had horrible luck with data on all AOSP roms running any modem. My phone usually has 1 or two bars of 3g but upon a restart or manually forcing LTE only I get great LTE coverage and speeds for a few minutes until it drops back down to 3g. Here's an album with screen shots showing my average 3g signal and when i force LTE only. imgur / a / 6fZK2 (Add .com & Remove spaces, cant post links yet)
Anyone else have this problem? Currently running the latest 12/26 CM11 nightly and the latest 12B modem. I figured the problem was not having updated modems for 4.4 as I had similar problems on my Gnex

Went to latest Stock, Data is back to normal again for me. So I know do believe it was rom related like you mention

Canadian ROM only shows 4G signal icon (with LTE speeds) - why ?

Hi all,
I recently bought a Galaxy S4 337M that was rooted and loaded with a custom ROM. I decided to go back to stock so went to sammobile.net and got the latest rogers firmware for my galaxy S4 (which they said was 4.3).
I loaded with ODIN, all went well, rebooted stock, but the max signal icon I can get now is 4G (even though I used speedtest and am getting close to LTE download speeds I think). Any idea why my LTE is gone ? Did I download the wrong ROM ?
I also noticed that none of the APN settings were there and no rogers apps were installed either. Makes me wonder if it was indeed a stock rogers rom after all.
Another strange thing is that it shows me a bell canada navigator update is available in the google play store, yet its not even on my phone. Regardless, even if its a Bell ROM by some chance, Bell Canada has LTE as well, so I am confused.
Btw I used the standard ltemobile APN settings that I always use on all my phones to get LTE (that always work)....
Any help or suggestions would be really appreciated, thanks so much !!!
My iPhone shows LTE using the same SIM...
PS. If I do need to get an original Rogers ROM, is sammmobile not the best place lol ? Any other places to go??

I believe that all I337M uses that same firmware but you need a CSC changer to make it change to your carrier as they don't release the specific ones with the carrier apps.
Search "Samsung CSC" in the play store and you should get one.
Thanks for the reply.
Seems I need root - which I deleted when doing a factory restore.
The strange thing is that it was supposed to be a rogers based firmware that I downloaded and flashed.
Maybe something went wrong in the flash.
Will try again.
And check out the CSC
i have a bell i337m and i have the same issue when flashing from a "custom rom to stock" and i have to flash the firmware using odin a second time and than i get my LTE icon enstead of the 4G icon, sounds weird and i can't explain why it takes 2 flashes to get it to show up proper, but it does.
i also have the problem with missing phone vendor apps, the second flash also makes these show up too.
also another thing i noted about my phone is if i don't root and install recovery to wipe, odin will dirty flash my roms, even though odin is supposed to wipe it isn't.
i've tested this to no ends, the results are 100% the same everytime.

After flashing the stock Rom, go back into stock recovery and wipe data and cache, then reboot that should fix it. To fix your csc issue there is a way to do it by dialling a number on your dialpad which includes your imei number then you choose a specific code. Search for it, google

Thanks so much for the replies and help.
I wiped the rom just for fun and rebooted and noticed that its actuality a BELL ROM (all stock BELL apps etc), but when I entered my rogers APN settings it still only showed H+, maybe due to network differences. It's frustrating because I specifically selected a Rogers S4 ROM from Sammobile.net. Any idea where I can get a stock rogers ROM for s4? Also do you think this may have affected my 4G/LTE issue ??
Either way, I will definitely flash the correct ROM twice, and then go back into stock recovery to to wipe data and cache.
Thanks again for all your help

T-Mobile GalaxyS5 m900t LTE issue

Just joined from the iphone world to the android world after about 3 years. Wow. =]
Anyway, just bought the phone yesterday, activated it an within 15 minutes had it rooted phiz recovery and and installed AllianceRom 3.1 on it.
I've had a bit of an issue, It will not go LTE. It only stay on 4g or go to E,, H+, my friend who has an iphone, same provider and same service, his phone shows LTE in our same location at his desk but mine will not go above 4G.
Did I do something wrong with the root process? Anyone ever seen this issue? I'd say its an issue with the service but when you have a friend with the same provider and his phone is showing LTE, it begs to ask questions
Thanks all,
Alan
do a speed test and u will know, i think on yr ROM 4G = LTE, H+ = 4G, also check yr APN too.
Got it Hope this helps new rooters

I checked it out, I found that it was a combination of a couple of things,
When I bought the phone I rooted it immediately, didn't officially update it or anything. I was working on the older radio with the newer Alliance rom which required the latest radio.
The only way I was able to fix it was use Kies, update it, which put it back to stock recovery and stock rom. Reroot using Odin and install Omega's rom. It would of probably worked fine with Alliance rom but I saw a couple things I liked with Omega.
When I updated stock I saw LTE. Which told me that it was a radio issue, I tried updating the radio manually but it failed so I just let Kies do it.
All settled and done, it's purring like a kitten now Thanks Koolboyztn for your suggestion

Hi,
The first thing would be to check your CSC and modem firmware. Use Phone INFO ★Samsung★ app to get all major info about the phone. It is important to know when you are going to flash another stock firmware.
I had issues last week with data and it was caused by bad CSC/modem. Flashed everything back to stock with official firmwares from SamMobile and it fixed my issues. After that, I was able to flash my custom ROM and everything is smooth sailing since then.
Let me know if you require more help.

I tried something new and I have interesting results.
I installed a Firmware U, it is a version of android 7. I installed it by odin and everything well without problems. When I restarted I put the SIM and it told me that I had to restart to configure the options of my operator. It restarted without problem and to my surprise it CONTINUES without Signal. In '' Access Point Name '' the APN of my operator's MMS has been created ONLY and AUTOMATICALLY. I did not set it up, it came out alone.
I still do not understand what problem this phone has. There are several people reporting similar problems with the upgrade to Oreo even in other S7 EDGE models.
Any ideas?????
