:{GTi9000 DTJP3 modem 4 MIUI!!!}:

Hello All!!,
I have been looking for awhile now for a good Australian modem for optus network to work with MIUI Rom.
I am on Galnet,s MIUI Rom V4 atm and find that the modems on his thread never do me justice. (I have tried JL2 ect.)
I have not seen a DTJP3 Modem for MIUI. is there one??
So I was wondering if there is anyone out there that can whip up a optus modem to use with the MIUI ROM. So I could flash it in CWM. I have tried to look into it but my knowledge is limited..
I will upload the latest stock Modem for optus network being DTJP3. Froyo based
edit: sorry wouldn't let me upload 12mb file but found a download link with DTJP3Modem.bin inside!
BIT OF A FIX: but still not a fast signal pick up! I Think it's something with MIUI ROM That has slow connection and Battery drain. Also was out and about yesterday with the wife and on same network and she could ring out but I had no reception. And I was on DTJP3 Modem. But when I was on Stock samsung in the same area I could get signal
OK,for people on miui having problems finding a modem for the country.
All you have to do is;
- Extract the modem out of your home town Rom
- Open up any modem.zip file from miui with 7zip (Pref. Galnet's modem zips)
- Replace the modem.bin with your home town one.
- Flash in cwm, boot...
That's it!!
For me it was the DTJP3 modem for Optus
Thanks to phalanger for the insight! thumbs up to you!

Maybe Codeworkx can help! I hear he is good at this stuff. He made the other modems for galnets miui...
Does Anyone know about good modem for optus network on miui??? and if there is anything else I should know about how to get good signal and battery?
Thanks!

[Q] Unlocked & Rooted Samsung Galaxy S I9000 signal issue

Hello, I recently bought an unlocked and rooted galaxy s i9000 from someone. Its running Dark Knight 5.5 and Devil Kernal. I have little to no network signal, wifi works great though. It has a rogers sim card in it that works fine in other phones. I have never had a connection issue and no matter where I go with this phone I have extremely bad service ! If anyone has some ideas that would be appreciated.
Thanks

What baseband version are you on?
System Settings - About phone - Baseband version.
I am having signal issues also.
I get maybe 2 bars then none then none sometimes.
I am running Team ISGS ICS4.0.4
This is really unreliable now.
My phone started doing it on Rel 4.2.
I used the KG3 modem and I now get FULL bars.
Here is a list of modems:

Sorry dude, i clicked the thank-you button by mistake. Have a freebie on me.
JW4 doesn't work in Canada. Here we need 850 & 1900, therefore KG3.
Flash the kernel again
I guess its due to the kernel.Dlash the rom.See to that you clear the Dalvik Cache too:angel::angel:

[Q] JB Wifi GSM Signal Problem

Hello there, i have installed TAJB Rom and it's great. Before and after flashing rom, i did factory reset and wipe cache. I have installed this rom over cyanogenmod 9. There was no signal problem on cm9 but in jb it's very poor. I can't get a good wireless signal even if i'm close to router. And gsm signal is the same. It was 3 bars in my room before flashing. Now its only one bar. What might be the problem? Which modem should i flash? I live in Turkey
Try using the suggested modem for Jelly Bean which is KF1. I'm from the Philippines and I had no issues with the signal even if the modem is for AT&T US/Canada. Currently, I'm testing KJ1.
Just experiment.

[Q] Cyanogen mod and modem.bin

Hi all,
owner of an old Galaxy S GT-i9000.
I've installed CyanogenMod 10.1-20130501-nightly-galaxysmtd directly from old standard Samsung installation.
It works fine (Apollo have some crashes but I can wait a stable version)
But there is a problem about modem.bin file and settings.
My offices are partially shielded so with the standard Samsung OS the modem signal go up and down like a yoyo but works (a lot of patience) depending also from position (no openable Windows ... http://forum.xda-developers.com/images/smilies/frown.gif )
With the CyanogenMod (also with stable version and not only with nightly) the line don't exist ...
Not only but if I go along the street the line is off ... I must restart the phone and all works with good performances.
I'm thinking that the modem.bin in CyanogenMod is for a different country of mine.
I'm in Italy and my provider is Wind.
Maybe there is a better (older?) version of modem.bin for Italy & Wind?
So I can install it via Odin in the phone or insert the zip file in internal SD and load it in recovery mode.
Any suggestion is accepted ... I can also testing several versions if it is necessary
Please an help is appreciated ...
Hi...I would suggest you to download getril from the market and check if your ril and baseband versions match...if not you can have some pretty bad problems when it comes to reception.
Also when ril and baseband don't match you can get the, i think it was the jvu ril from the app itself....then flash the jvu modem from here
http://forum.xda-developers.com/showthread.php?t=1870460
Another thing that could be is, that the 3g reception in your area is a bit weak....try to force 2g networks and check if it is getting better for you

The reception 3g or 2g is weak because the building is "shielded" (many iron and iron gates so it seems a faraday's cage) ...
I'll try to dl the app you suggest me and I try to use the jvu modem version ... the std should be the jw4 ...
thank a lot I'll give you all feedback

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

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
