Update modem files - Samsung Galaxy Note 8 Questions and Answers

My reception is horrible. I am on the Verizon Note with the Baseband 1AQI5 using Samfail V1 and running Chimera V2.5.
I want to know if the modem files can be updated or tweaked for better reception without having to wipe the system or updating to newer bootloader?

I've just been looking for something similar and was about to post when I saw your thread.
Only difference for me is that I'm in the UK with a SM-N950F

no LTE on P3720T with P3720 ICS roms (i.e Arlics)

Hi there,
We tried to update a telstra branded P7320T Gtab (Honeycomb 3.2) to the ICS releases based off the 4.0.4 drops from Scandanavian providers for the P7320 i.e Arlics Rom (this thread http://forum.xda-developers.com/showthread.php?t=1923371 ).
Everything works fine; however 4G APN's do no register, this is most likely a Kernel/Qualcom band mismatch with the Telstra baseband and the updated kernel version in the ICS builds.
Arlics rom does not contain modem/basebands so it is most likely the updated kernel drivers in the 4.0.4 drops misbehaving with the P7320T baseband used by Telstra and Telecom NZ's trail.
Reverting to the Telstra stock solves the problem.
This was tried off a Test Telecom NZ LTE APN (no UMTS functionality - UTMS works ok however).
I would like to hear from any Telstra Australia users who know they are in LTE areas whether or not they get LTE on Gtabs running this rom.
- Apologies for posting here; and not in the thread, the forum policy prevents me from posting their.

Similar experience
I had a similar problem. When I flashed the leaked rom (which wasn't from a Scandinavian provider, by the way, but from a Polish one - forums got it wrong), LTE stopped working. Haven't tried Arlicc's, reluctant to especially now that it seems abandoned.
Sad that the 7320 gets so little love Official ICS release here in Norway has been delayed yet again for the umpteenth time.
You should try the latest version available (XXLPI - to be installed by Odin, no wipe necessary). It seems much better at switching between 4G and GSM/CDMA than the early ICS OTA version I used to have (the one the Arlicc's ROM is based on).

Are you using that on Telstra's network ? Can you post the baseband version?
Sorry, I'm using it in Poland however it's dedicated for other parts of Europe. It contains an upgrade to baseband version P7320XXLP7.
Did not succeed
Until I downgraded this to the last NCM version (a Honeycomb version) again, I couldn't get LTE to work. The TEN Ice Cream Sandwich version from 5.12 did not permit LTE, despite being a Norwegian carrier and me being in Norway.

Network Signal Low since 4.3

Hello,
I have a Samsung Galaxy s3 and ever since going to 4.3 my signal strength for mobile is weak, very weak.
I have re booted phone, taken battery out, tried different modems but all with no luck.
Has anyone else had this issue and successfully fixed it?
Cheers
Got the same issue, as I flashed the new Alliance Rom on my S3 LTE. Most time I had just one of five network points.
So I did another Full Wipe, and used the Boeffla Kernel with stock modem.
Got slight better results, but there are always lil interferences while talking. Probably its the bad network by german T-Mobile.
Regards
I have the australian optus version and signal where I live is really crappy on 4.1.1 I upgraded to 4.3 the newest one from hong kong (the one my rom is based off) and now I have found that the modem and ril driver in that version is giving me stronger 3g and 4g signal
Sent from my GT-I9305 using xda app-developers app
what modem and ril driver do you have now ? could you please share?

I am in Hong Kong with the following
JB 4.3 XXUEML8 rxtreme JB 4.3-V2.0
Hong kong modem ZHUCMK1
Stock kernel of XXUEML8
My house is at 35/F of a building, my phone will have signal as stated below:
LTE/WCDMA/GSM signal with 2-3 out of 4 bar
WCDMA/GSM signal normally full 4 bar
Hey everyone I am back developing again haha Noticed this myself with 4.3 so I have looked into it and noticed something very different with 4.3GSM RIL class files. They are are all reverted to the standard GSM ril type files, where as on all previous generations have used QMI based RIL.
I have created a patch that I am about to test and if I have any luck I will upload it here for you guys to try out for your selves. It should work for other countries as well so long as you have noticed a difference in the RIL types between 4.3 and 4.2 or earlier? If not then I would suggest leave things as they are and flash a new modem.
I am on Optus and I am comparing the first 4.3 release to a stock Optus Android XXALI5-OPS, does anyone know what the version number is called from the OTA update for Optus?

I have the same problem. My wife has an I9305 and I have an I9300, both with 4.3, my signal is way better and usually get H+ internet and she just gets Edge.
Any progress on the fix? I would love to have the patch, or even just the information on which files to change and what to change.
Thanks

[Q] android and radio clarification

I need some clarification regarding android and radio baseband.
I'm running latest cm-11 nightly and my baseband version is XXUEMK1
Is this radio included in the cyanogenmod ROM or is it a separate partition that wont get updated with a ROM flash?
I've found the thread with a list of different radio ROMS for the i9305. Are these optimized for different countries or will they work regardless of country?
Is there a way to backup my current radio if I want to try a different radio and need to revert? XXUEMK1 is not listed in the thread with all the ROMS.
Found some information in another tread:
Baseband / Modem / Radio - This is the software that manages your connection to wireless networks, be that voice or data. Unlike unrooted users, you can download and flash any number of i9300 (Versions for other models WILL BRICK YOUR PHONE) or i9305 radios pulled from official ROMs. I wouldn't waste too much time on them. Usually what your official ROM comes with in your country / for your carrier, is the most optimised for you. Try a few by all means but don't waste time testing every last one.
Be aware that Samsung official ROMs come with a baseband. Often this means Samsung based custom ROMs may also do so. Some ROMs which install using the Aroma installer (A kind of set-up wizard) may give the option to not flash the baseband. AOSP ROMs almost never come with a baseband. When you flash a ROM withotu a baseband, the previous baseband remains. You can by all means, mix and match ROMs and basebands. You are not tied to the baseband with the same build number as the ROM. For example, if you are on XXEMB1 ROM, you definitely do NOT have to stay on the XXEMB1 baseband.

I've kind of same issue.
My SIII LTE is working fine with CM10 but when I upgrade to CM11, it doesn't work anymore :crying:
I've almost everything working apart from the MODEM and for a phone, I'm sorry to say that it is annoying
I'm using my S II with OMNI ROM and I miss my S III :crying:
Any help will be welcome :good:
I attached a screenshot of my system.

Question about custom rom and Baseband

Hello xda Community,
I've downgraded the baseband on my p880 to v10h due to some issues with GPS and provider signal.
I've used some custom roms before and the issues appeared at some update when I was on MoKee rom but I can't remember which update it was. The downgrade improved the phones performance and I have no issues with GPS and signal.
My Question: If I Flash a custom rom, - will it also update my Baseband? Say I'll flash a 4.3 Rom (I'm currently on 4.0.3) will it update my Baseband aswell to v20x?
Thanks in advance.

Don't think so. I haven't even really seen any indication that the community understands HOW to update the baseband firmware. This phone has the radio on an entirely different chip with dedicated flash and ram for it. There are soft switches to throw (look but do not touch) in the hidden menu that switch the USB port over to it for flashing but nobody seems to know how to make use of that knowledge other than the official LG utilities. Flashing a third party ROM is entirely about replacing the unencrypted/unsigned partitions on the main application processor's flash.

No Nougat Update for SM-G610Y

Can anyone help me with this.
All the other versions of the J7 Prime (G610F & G610M) have recieved 7.0 Nougart update 6 months ago.
My phone is pretty much the same underneath as the rest of these, No my phone is not carrier locked.
I'm not the only one having this issue, there are a lot of people in the Philippines, Pakistan and here in New Zealand who are wanting this update and cant get it.
Samsung wont tell me anything no matter how much I ask their help desk and support team
I feel like as a customer I deserve to at least know why I haven't got this update but the rest of the world has, and not get continuously told to turn auto updates on when its already on.
Same device bro
Bro, i am a Y variant and i'm on PH. We don't have a choice but to install custom rom to taste the nougat android. Just root your phone, install TWRP then install custom rom like NovaOS or Lineage OS 15.1 for J7 Prime. Just search it and you can find it.
Same issue here...just installed Xenos Rom and its more than enough for me with the features....there are other roms as well
same ;(
Ah, those lazy Samsung coding teams...
My condolences, but you can always install the ROM closest to stock.

I actually downloaded their Nougat based stock rom and flashed it using ODIN. No problems so far... it's just that you won't be able to use their country specific apps which I think is not a big deal.

There are no specific apps for Philippines G610Y except when you purchase through a Telco where settings like boot screen / default web pages all point to the Telco. Flashing Aussie Official G610Y ROM should be fine. In fact this should be a good base to create a custom ROM as it may contain updated drivers and the like.
I been running the Nougat Note FE XenOS v.1.1 without any problem so i dont need to worry bout waiting for an update from OTA

One minor problem I have encountered so far now is whenever I switch to 3G/2G on network mode, it doesn't survive the reboot. It reverts nback to 2G/3G/LTE mode. Other than that the Stock ROm is stable so far. Battery life is incredible.

Need to troubleshoot 1x1. First, I noticed you are using Oxygen kernel. It could probably be an incompatibility with this one.
Another, which I can think of is incompatibility of CSC part if you didnt change your original.

It was still present when I was still using the stock kernel. About the CSC though I have no idea. But maybe you're right because I flashed the original CSC tar.md5 file that came straight from the stock Aussie Nougat ROM. I don't know how I can change it. (Perhaps flash the stock CSC from MM?)

I checked my csc if it changed , and yes it was changed together with xenos. So it might be something else. But then there are CSCs which are not multi CSCs. So i could be wrong.
Edit: ok i did some googling. CSC doesnt affect network selection its the baseband part. You can install phone info samsung to check what versions you are in.

Just tried flashing the old MM modem.bin Seems to work like a charm. Although the network mode still reverts the 2G/3G/4G mode, I'm getting consistent 2G signals now and no more signal drops. I just use 4G whenever I use the phone outside where there is no wifi or when I use Navigation apps like Waze. I assume it'll get the 4G/LTE signal when the signal is strong enough.

That still puzzles me as well. No matter how many reboots I do it just doesn't want to stick to 2G/3G mode.

Can you kindly guide me on how to flash modem.bin? I flashed NZ Nougat stock ROM on PH-bought G610Y and I'm having problem switching network mode when using dual sim. If I disable sim 2 I have no problem. But when both sims are enabled I can't swith sim 1 from 2G only to 4G/3G/2G. Switching doesn't do anything. It's stuck in 2G only.
Do I simply flash the file that starts with "CP"?
Update: I went ahead and flashed the CP file from Marshmallow and problem is fixed. Thanks for the tip!

I am experiencing problems with the new facebook app on XenOS v.1.1 FB is important for me because I need it for work. So, I decided to flash the New Zealand Nougat G610Y. Here are the steps I took for successful installation official nougat on Philippine based phone:
1. I flashed latest XTC G610Y MM so all partitions contain XTC (Philippines) based settings/customizations (BL / AP / CP / CSC)
2. I flashed G610YZTU1BRC3 Nougat (BL / AP) only which means CP/CSC remains XTC (xtc is multi CSC)
3. after step 2 finishes flashing from ODIN, it will encounter an error, but it will go to recovery mode
4. at recovery mode, I simply reboot the system and enjoyed a fresh copy of Nougat
I did not encounter any problem with network selection and tested rebooting it as well. Hope that helps your problem.
Please Assist me on this (i mean step by step instructions..)
