Signal drop and antenna issues - Focus General

Am a total noob to this flashing world
but couple of days back i flashed my phone used a custom rom
cooked by ahmedfikry based on CLEANROM from that moment am facing
Signal drop and antenna issues
please help

It's a bug on Samsung wp7 phones(some said) and tango is a beta ROM(it's not released to the public so it still has some bugs). Run samsung network profile app(marketplace Samsung apps) select a different network carrier as yours. wait to set it (you will see 3G/E sysmbol) then select your network carrier(it depends on what network you are). If your on at&t try it (some people said it works). I'm on Straight Mobile and had this problem on the stock ROM and didn't work(this app only gives you 2 choices AT&T & ATT for my phone at least). Try flashing [ROM] Clean ROM - Stock METRO UI http://forum.xda-developers.com/showthread.php?t=1528984 ver. 1.30(mango) it works flawlessly. Tango is still buggy because it's a leaked ROM and not final.

No, the phone should be unlocked irrespective of the number of times you flash/format it. AFAIK, the unlock is in NVRAM aka non volatile RAM.

[Q] - i9507: No service on KitKat - Can receive calls, can't dial (no service)

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?
Current info:
ROM - [ROM] KOT49H【4.4.2】 GOOGLE EDITION 4.4.2 by Danvdh, Kryten2k35 & Ktoonsez

I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!
Thanks =)

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

[Q] How to use EDGE network mode Sprint S4 ??

the phone uses HSPA+ which well if you are a pre-paid customer in a 3rd world country find it hard to manage. it chews up all my airtime within a minute or two, so i went custom. installed Omni ROM 4.4.4 and found that GSM Only radio button, which is missing in the official NG2 4.4.2 ROM. then i did sth wrong and had to flash the official ROM again but look, it retained the settings from the omni rom. that's when i discovered it had the icon for E. so am guessing there's a work around without having me to flash a custom rom, or is there not?? Please Help!!
Solved!!

My XT1570 is recognized as XT1575 and is out of service all time.

Model: XT1570 China Dual Sim (using only 1 sim)
Carrier: China Telecom 4G
ROM: DU Official V10.6 (latest)
I have had great signals when I was on previous DU builds (Mashmallow) but the signal became unstable (completely on and off) on the latest build.
I tried changing a few options not knowing what they actually do in "Settings"->"Mobile". There was an option I can't remember but it seems I changed it from "automatic" to "home only". Since then my phone has been out of service forever. And this option has also disappeared from the "Mobile" submenu too.
I also noticed that my phone model in the info shows XT1575 instead of XT1570.
I guess I first need to make the phone to realize what model it actually is?

I flash a customized rom just to use google. So flashing back to stock is not my solution.
But I had used the DU rom for several months and all have worked well. So I think there is way to get it to work without using stock rom.
Can't you just roll back to an older version of DU and stay there until you can get the devs of DU to look at it?
In general, the Chinese models are identical to asian models, just without Google... Can't you just flash a gapps package on the stock ROM?

S7edge SM-G9350-NO 4G DATA**I WILL DONATE $50-$100 TO WHOEVER GIVES ME THE SOLUTION**

The exact model is Samsung Galaxy S7 edge SM-G9350 64 GB GOLD PLATINUM
First I want to get this off my chest. I registered this week (I used XDA before like 7 or 8 years ago in high school when I use to flash custom ROMS on windows mobile phones-good times hehe)because I am frustrated since I bought an unlocked Samsung Galaxy S7 edge from a stranger using craigslist on Sunday night. The ad said it was T-mobile Unlocked and in brand new condition with the box and original accessories and it had some pictures.So why not buy it cheap for since I'm using a T-mobile LG-K7 with a cracked screen,right?WRONG!! The phone is working fine except I am only getting EDGE data!!! I found out that it is a chinese variant and it works fine with my T-mobile sim card here in the U.S.A except it can't connect to 4G and that is probably why the shady guy sold the phone cheap to let it become someone else problem I also saw 1 or 2 of these models in the box as well and he said a friend gave it to him and he is just selling it(B.S.) I forgot craigslist had scammer like 40% of the transactions lol, I use to meet these types of people in middle and high school when I bought and sold my used or old T-mobile phones though I never scammed or conned any one.I remember some people would act shady or too nice for no reason,probably cause they stole the phone and were making 100% profit off me.This same guy is one of them.
ANYWAYS THANK YOU FOR READING MY RANT---- NOW ON TO THE POINT OF FIXING THE DATA ISSUE
I am getting unlimited 4G on my k7 and everyone else on our plan is using unlimited 4g just fine.Samsung rep at best buy said its legit and its an international chinese variant and to look around on here to fix the issue. He told me something about the band and t-mobile towers to pick up the frequency. He said I got a really good deal if I can 4g on there. If not than re-sell it and make it someone elses problem. I looked all around google the past few days an either no one has this problem or if they do than the solution doesn't work on my phone.
Here is what I tried so far:
A) T-mobile reset the network connection via tech support
B) I factory reset the phone numerous times
C)I got the right APN settings set on the phone to be connected to nearest towers, a store rep did it for me to make sure.
D) I replaced and used another activated T-mobile sim card
E) I download some apps I saw on here to check LTE signal etc and its running very slow edge
*********I am on the sim status screen and right now as I'm typing this the signal strength is
-61 dBm 26 asu,cellular network type is EDGE,NETWORK is T-mobile, Service state is In service,Roaming is not roaming,cellular network state is disconnected*******
------I hope someone can pick up information off of that and maybe I could change some settings
E) I dialed *#*#4636#*#* and got to a screen to allow me to check phone information,battery information,usage statistics,wi-fi information-under phone information there are options to set preferred network types to: WCGMA,GSM, GSM auto(PRL), CDMA auto(PRL),CDMA only,EvDo only,GSM/CDMA auto(PRL),LTE/CDMA auto(PRL),LTE/GSM(PRL),CDMA auto(PRL),LTE only,Unknown. It will only stay on up to GSM auto(PRL)
....also when I press menu on this screen there is an option to enable data connection and when I click it,it won't stay,it just keeps saying enable data connection
F)I googled what bands this model and it is able to use and it has the capability to be used on T-mobile bands
What else can I do get the data working to 4G right now? The phone is running Android 6.0.1 and won't update to Nouget over the air. I want to root the phone and see if I can install a custom Nouget rom( since the samsung guy said the phone will brick if I try to install the T-mobile Nouget rom or I can't even do it since its an international variant-by the way I am able to have google services on here like play store,etc. so I don't know if that makes a difference to what variant and rom it is because I heard one or the other of hong kong or open china variants for this phone is better and can't use google play)and maybe I am able to connect to 4G data.
Like the title of this post says, I promise I will back up my donation I really don't want to sell the phone unless I have to because I will not get a better deal anywhere ever again for the latest high end phone from a manufacturer

you have to flash the correct CSC this will fix your 4G if you buy an device from a other country than is it possible that you get this problem but when you flash the correct CSC you will get 4G i helped so much people with this problem with a S7 device, i think this your solution
if this fix works for you just keep your money we are developers not for paying
Maybe you should post this in the T-Mobile section.
In my idea this should have 4G data on T-Mobile US out of the box as the required LTE bands are supported by the G9350. Did you check the APN settings? (VoLTE and WiFi-Calling may or will not work without t-mo-rom but that's another topic)
Also you should be fine to flash a T-Mobile US rom as both have Snapdragon SoC. You don't need root to flash an official rom.
Out of curiosity: what about 3G?

Thank you so much!!! People have actually asked through pm to donate to bitcoin first before helping me and here you are helping me first by the way.
I am going to find the correct CSC, what does that stand for? Can I flash a T-mobile 7.0 Nougat rom on my Galaxy SM-9350 first that the person before you replied about(its the link)?? I want to do both to have T-mobile settings and to use the 4G although the 4G is a thousand times more important. If I can do this than I am a happy man!
Why is there a boot loader and modem link attached to every post containing a ROM download? Does that need to be downloaded first,and what are the next steps,if so? I know these are questions I need to search about they are all confusing and mumbled and jumbled up. Even though I registered this week for help I was a member here like 8-9 years ago in high school when I was flashing custom ROMS on Windows mobile phones(good times hehe) but it got addictive,took a lot of my time from studying, and I totally forgot how do things.

Hey I made a new thread today in Q&A for GS7. The APN settings were put in by a T-mobile store associate and it still didn't work. I don't care about VoLTE/Wifi-Calling although I noticed some people on here are worred about that-its just something I never use.
Are you sure I don't need root to flash an official ROM?The Samsung Galaxy guy at Best Buy said it would brick if I used an official ROM because the phone is an international variant. If I can use an official ROM,I can't get Nougut OTA via T-mobile anyway as my phone keeps saying it is updated even though it is 6.0.1. How do I get the offical ROM manually on the computer? Samsung Smart Switch isn't even recognizing my device when it is connected and Smart Switch on my phone looks like it is only suppose to be used to receive files from another phone? I have the link for a T-mobile 7.0 ROM from a post on here that he used on the same exact model I don't know if I am suppose to root the device first or not yet since it looks custom made.
Thank You for helping me out it means a lot you guys are the best! I can already see myself on here a lot in the future doing stuff different android phones like I 8 or 9 years ago in high school on windows mobile phones.

The only data I am getting is EDGE
So, I guess something is wrong.
You can try flashing the designated firmware for this device first and see if this helps. To get the right one (who knows what all was tampered with) use best the Phone Info tool.
I've had this exact issue before, with a Nexus 5 that I bought from Telus, I am with Telus, it ended up being I had to go buy and register a new SIM card, then it was fine, might not be a solution for you but Worth a try,
Actually get a SIM card from your provider, have them register it in the store

I choosed this rom cause it got nougat bootloader and kernel. Also download CSC chooser zip: https://www.androidfilehost.com/?fid=745425885120710484
3) Install twrp via ODIN and uncheck auto reset in odin. Then press power + home + volup to go to recovery. Put the superman rom and CSC chooser zip files on Sd card and put back in phone.
4) Install Superman rom,in aroma pick superstock kernel 'samsung pay and knox work' and install/update everything especially the bootloader. In mods stick to stock as possible.
5) Install the CSC zip file and choose t-mobile USA.

Nice, I like what you have! My model is different so I don't know if the ROM will work though I'm almost finished downloading it at the moment. Instructions 3 and 4 is confusing. Don't I need to put superman ROM and CSC file on sd card while the phone is ON?And am I suppose to transfer it on there via usb cable or can I also do it via google drive than open in up phone gmail and put it on sd card? Also do I need to extract the CSC file first to my computer desktop? That file takes forever to extract! Is instruction 4 suppose to be while in recovery mode? Also is it normal for my phone to show "no command" while in recovery mode?
Thank you ?
The rom will work because your phone is exynos based. It got a different model number because it's for Chinese markets. Put the rom on the SD card using whatever method, just do it before flashing the recovery, because your phone may not boot after the recovery to the stock firmware because Samsung has put some crap to prevent using custom firmware. I forgot to say that also before doing anything go to device info - > software - > and press build number several times to enable developer options then back to settings and go to developer options and enable OEM unlocking.
Yes, commands 4 are made in recovery. Install - > pick the zip file and install.
All zip files aren't extracted! The recovery uses the zip file as it is.
Good luck

Were you able to flash the U.S. T-mobile ROM onto SM-9350?
The official firmware can be found on https://www.sammobile.com/firmwares/database/SM-G935T/
I found it yesterday but their free server is under maintenance so he will have to pay to just download a firmware file.
I don't know why don't samsung provide them for free on their site!

Lets Talk about Sprint!

Hya Everyone! I wanted to try and open up some life into those of us still using the Sprint Variant of the Note 4. It is so easy to get lost in the noise of the general forums and what works for the Korea variant may not work for our CDMA variant! So with that... let me hear what ROM you are using and how you like it! Also.. did you upgrade the Baseband past QI5? Any regrets??? Here are my burning topics.
1. SMS over LTE
2. What happens with T-Mobile? Should we load the T-Mobile basebands?
3. Absolute most stable ROM.
4. What version of TWRP are you using?
5. WiFi calling and/or HotSpot use.
Share your stories!!!
Lets also talk about how to switch our current phone to TMobile!
Uh, yeah. NOT much love for the CDMA variants of the Note 4 for newer OS's and the SMS over LTE AKA SMS over SGs issue. I'm currently running LOS 14.1.2 (Android 7.1.2) because anything much higher on QI5 wouldn't send texts. I found an older post where someone flashed an older previous baseband (Android 6?) using the newer OS's and that worked to fix the SMS issues, but I don't know how to make the "correct" needed files (which I have) into a TWRP flashable zip. After more digging, TWRP itself has the baseband files built into it, so flashing an older version might work, but I gave up after screwing around with it for 3 months.
"What happens with T-Mobile? Should we load the T-Mobile basebands?"
As long as your Note 4 is working on LTE fine there shouldn't be any difference Sprint vs T-mobile from what I've been told. 3G is going to be shut down in Jan 2022 though so...
I wouldn't upgrade the Baseband to QI5 because it seems that locks out older solutions for the SMS over LTE from working.
Absolute most stable ROM?
The only ones I've seen being regularly worked on still is the unofficial Lineage and Havoc OS's.
