Hi,
I have some problems with modems and signal strength... I have search other threads but did not find anything really useful.
I bought an i777 when I was living in America for work, but now I'm back to Italy and I see that I always have bad signal (I've checked also with Better Battery Stats). I've tried different modems, but didn't see remarkable differences...
When other people asked for this stuff, the answer was almost always "install and try". Do you know if there is another way to test modems?
Since the i777 is from an American carrier, is it possible to port an i9100 modem?
Thank you!

Short answer is no, i9100 modems will not work on an i777. While the devices are alike in many ways, modems from the i9100 aren't compatible (or portable) to the US variant. You can flash an i9100 modem and the phone will boot up fine, but you'll run into trouble with not being able to hear the caller/them hearing you. Normally this workaround would be to flash an i777 kernel with MicSwap capabilities, but that will have no affect on a modem as the baseband's are different.
Perhaps a longer answer than you needed. Sorry, I'm not aware of a real solution for you other than purchasing a different device for your region.

Thank you for the answer SteveMurhpy! I can't change phone right now, so I'll have to try the other modems... do you know if there is a faster/better method to test them than to install and try? And how much does the version of the OS interact with the modem? I am on Slimsaber right now... Thanks!

I don't think the OS has anything to do with the signal strength, if it did it would likely be on older firmware such as GB, ICS and not the KK version you're currently running. As for the modem, unfortunately there's no way to test signal strength prior to flashing, so you're just going to have to keep trying them until you find one that works in your country.
One might suggest alternate APN settings, but that has more to do with functionality and speed rather than signal strength.
Sorry, as far as I'm aware there's no easy fix for you.

I had some doubts about the compatibility between modem and OS because when I was back on SlimBean and I flashed a modem from GB the System UI kept crashing... but maybe there other types of problems, I didn't investigate that much.
Ok then, I'll keep trying... maybe I'll find the right modem for my country!
Thank you very much again SteveMurphy!

Hi, I am opening this sub-forum for N7005 variant as its a closer relative to I717 than the international N7000 note.
So far, as read and tried from other earlier posts, I managed to root, flash CWM, flash TWRP and flashing of various roms from this I717 Forum without any issue, yet. No changing of modems. So far, no issue with basebands so 4g still works great.
Roms I have tried, the original Paranoid Android and the Cookies & Cream. Both are great roms.
Hope that the Mod dun close me down on here.
Cheers!

Are you trying to say that you had use the same firmware to root your lte note using i717?
yup..
Followed this method.. TWRP same as I717.
http://rootgalaxynote.com/galaxy-note-i717-roms/how-to-root-att-galaxy-note-sgh-i717-icsgingerbreadeasiest-method/
Original thread that I read was from here
http://forum.xda-developers.com/showthread.php?t=1876490&page=2
This is a good thread. I have been trying to find the N7005 all over google and got very a little and mostly, 'irrelevant' results. I believe the note LTE might be a different from the N7000.
Would also like to know if you already have successfully installed the I717 custom ROM on your N7005?
Yes.
I am starting to believe ours have the exact same hardware as I717. It just carry a different model no because of the different baseband.
I have tried ( and successfully flashed ) the original Panaroid Android, the Cookies & Cream, Unofficial CM10 and Liquid Jelly. and also a kernel ( cant remember the name..) All worked well apart from issues with the standard bugs from the current developement of Jellybean. Just be careful not to touch the modem.
There is one little problem though.. I cant really find a convienent way for ours to flash back to stock or remove root if I ever need to send back for official servicing. The only solutions on the web suggest flashing US Carriers specific roms , which does not apply for us.
Well actually, there is a way to go back to official stock.. 2 day ago there was a minor update from samsung. so I flashed and it remove the root. And my firmware now read, Official Samsung.
I haven tried flashing again as I felt that though all the developers are working very very hard for JB and I do really appreciate the efforts , imo its not that stable yet.
Its pretty safe, I tried and they worked. BUT, PLS DO A BACKUP OF YOUR STOCK ROM!! Need any more info, I can share.
Disclamer: I will not be responsible for any kind of damage, bricked or blow ups...
And, U have to understand that if things goes wrong during flashing or any weird errors appears later, the developers are not oblige/not able to help as the I717 stuffs just " happen to work " on our device.

I'm currently still stuck with my SGS, looking at N7005 when my contract expires. You said don't touch the modem, why is that the case? From my understanding you can just flash the baseband back on my SGS, is there an issue if you flash another modem on the N7005? Region issue?
The SGS have great international and local support. Any resources are readily available.
I717 is pretty much confined to the US. Their modems are specific to their baseband's bandwidth. There is no such modem in our region that u can safely flash that is guaranteed to work with our carrier. I know HK they have a forum for N7005 but its all in chinese. I am not too good in that. And, I dun see any real needs to flash the modem as well.
BTW, for local users that have a habit of flashing roms, I wouldnt recommend this model at all. The device is great but zero local support. I have even checked with Official Samsung Singapore and they dun even know if N7005 is getting JB but Original Note N7000 will be and the Note 2 will launch with JB. Go for more sensible options my brother...
I bought this purely because it was cheaper that time. And I traded in my nexus so this phone was basically free.. Then later I realise I will have the flashing "issues"..

I did look at the original note and S3, but what I wanted was larger display and I have a budget so I might not consider Note 2. I wanted to get LTE Note since it supports LTE and it would be a waste if we didn't make use of that.
I did see on starhub website that it states it is upgradeable to JB, but their website is always providing inaccurate information. Thanks for the recommendation, might reconsider. :good:

Can I have the link, please?
The 4g would come in handy for sure. I actually turned that off coz its eating my battery like theres no tmr..
Regards the HK forum, I dun have the link anymore.. ask Google my friend..
I realised the information on our local telco (Starhub) said processor is 1.4 Ghz, but the SHG-I717 is a 1.5 Ghz Scorpion.
Also the firmware stated on Samsung website says it should be ICS instead of GB, where Starhub says its GB and upgradable to JB?
So which is correct??
Look elsewhere for information. Believe the opposite of starhub. The specs they listed belongs to the international note N7000.
Hi dude, can u please show how u did to sucessfully to flash this stock roms to pandroid rom.. thank you in advance

hey there,
are here some bob-austria-users using cm on the sgs2?
which modem do you use?
i have so much trouble with my data connection and even sometimes with gsm...
wär für jeden hinweis dankbar!
ps: radio/modem is independent from the rom and its version, isnt it? or does the rom-version affect the quality of the modem?

Goto http://samsung-updates.com/device/?id=GT-I9100 and look for the BOB/A1 Austria code (ATO). Click the link and you'll see that XWLPW was the latest Samsung ROM for the i9100.
Download it, flash it, look for the modem that goes with it, reflash your CM10.1 backup*, download the modem, done.
You'll now have the modem of your provider. This should be "the best". However, "the best" is a relative thing: what is the best for you, may not be the best for someone else. The only way to find out for yourself is to test signal strength and data speed in different locations and at different times. Possibly you're in a low reception region. And when you're roaming, a totally different modem may be best for you.
Or ask in http://forum.xda-developers.com/showthread.php?t=1131950.
Modem XXLQ6 and XXLPS were good to me. Try them. Now I'm testing an old modem of my provider (see my signature).
CM doesn't come with a modem, since it is used all over the world with lots of providers. If you're clever enough to flash a custom ROM, you'll be clever enough to find your modem
Maybe there is a modem/RIL mismatch. Install GetRIL free and flash a matching RIL. See also http://forum.xda-developers.com/showthread.php?t=1187681 and http://eric10234.wordpress.com/2012/10/23/samsung-galaxy-s2-i9100-jellybean-cm10-real-ril-crash/. Don't be scared about the RIL crash thing. It only happened to me with LS6 modem and/or RIL.
*When using stock Samsung, you maybe first have to flash a rooted kernel to get CWM Recovery. Use the method described in the CM9 thread or just flash the whole CM9 ROM using the Odin method.
Tip: when asking for help, always give information that is related to your problem.
So: what modem are you using; what modems have you already tried and what were the results; are you still on CM9 as your signature is suggesting? Also give general information like phone model (obvious), ROM name and version (saying latest nightly is silly, always name the date), modifications.
Edit: just finished downloading the XWLPW A1 Samsung ROM, extracted modem.bin, entered a hex editor, searched for the string xxl and found the text "120626.I9100XXLQ6". So I'm assuming that modem XXLQ6 comes with A1 Austria.
thank you for the detailed explanation...
i will see into it..

Hello everyone
I have a SGS II GT-i9100T which is a gift from my brother from New Zealand.
I´m running CM 10.1.3 and sometimes my signal drops, "Emergency calls only"! I´ve tested the Simcard on other phone and it´s fine.Could anyone suggest me a modem to flash to my phone?
I´m living in Germany and using O2-de.
Thank you.
Here is some info in case you need them:
i am not very sure whether geographical location affects modem or not, but there was a country based thread for India. They have some popular modems listed out here -
http://forum.xda-developers.com/galaxy-s2/general/i9100-modem-reviews-india-user-based-t2184193
You can get flashable modems here - http://veyka.co.uk/sgs2/radios/
have fun testing them.
Forget the fact you're in Germany; stick to modems bundled with stock roms released by carriers who sold the I9100T. Go to Samfirmware, use the pulldown boxes to make a list of all the stock roms released by carriers which sold the I9100T (there aren't many). If you click through each stock rom in turn it will list the modem - make a list of all the modems. Then search for CWM flashable versions of these modems on here (easily found with a search), download them, and start testing them out.
Only if you get to the point where you've tried all of these modems & they don't improve your connectivity should you consider flashing regular I9100 modems (I know this because I have an I9100T).
You might also be suffering from a long standing problem with CM roms where connectivity just goes away for no particular reason at all. The way you'd test if this is the case or not is to do a clean install of a stock rom released by a carrier which sold the I9100T (doesn't matter which, but don't flash 4.0.4).
I missed on seeing that the phone involved here is i9100T. My Bad.
Apologies for feeding you wrong info here.
sorry for "ruining" this thread, but:
1. How to know what the best modem is for you (I live in the netherlands).
2. Can you flash a modem on any android version? (I'm on carbon 4.4.2 rom).
3. Is it safe like rom flashing?
^^^
1) The way I always tell people to approach this is similar to what I said to the OP; go to Samfirmware, find all the stock roms released by your carrier, click through on each one & make a note of the modem. Search here/Google for CWM flashable versions of each modem, and test them out. If you find you go through all the ones bundled with stock roms released by your carrier & your connectivity is still bad, do the same with modems bundled with stock roms released by other carriers in your country. If your connectivity is still bad after that, flash any modem you can get your hands on.
But for most people, modems bundled with stock roms released by their carrier should work best; rationale being you'd hope the carrier would have fully tested them to ensure they work for most people most of the time on their network.
If your connectivity is currently fine, there's no need to go messing around with modems. Chances are you'll make it bad if you do I.E if it ain't broke don't fix it. Only mess around with modems if you have problems with connectivity.
2) Yes, modems are independent of Android version.Same risk as flashing anything else (I.E very small risk of the flash going bad with any given flash).
3) Risk should be minimal; I've never heard of anyone borking a phone with a modem misflash, but anything is possible I guess.
hi guys,
I purchased a used s3 from eBay that was unlocked to all cariers but was originally on Orange network.
I rooted it and flashed ultimarom 16, which is great. but my signal is awful.
I am on three UK network and maybe I need to flash a different modem?
please help =(
help
I've tried same rom with similar problems in my s3.. changing modem will help, but I completely solve the problem by changing rom... I'm tring the SlimKat, and I never seen my s3 working so fast... don't have to charge it everyday and the signal is so much better than ultimaRom for me

I live in Italy and my provider is "TIM". I'm still with SlimRom and enjoyng it.
You can easily flash modem .zip files from recovery if I remember well, just take a look on google for i9300 baseband/modem "yourprovider", and you will get some of them..
Hi,
I have an issue with the radio of my phone. When I switch to 3G, I get a weak signal varying between one and a max of 3 bars. The phone gets heated up and the battery starts draining. Please find below the device and OS that I am using
Device: Samsung Galaxy S2
OS: CM M12
Base band: I9100DDLP8
Location: Bangalore, India
I have inserted my Sim in a different phone and have found that nothing is wrong with the connectivity in the area. I have no issues when I switch to 2G. I have tried flashing various modems and RILs but in vain. I have also tried using the Getril app to correct the issue but without much success.
Here is what I have tried and noticed
1) Flashed the modem DDLS9 and DDLPB. The 3G signal strength is good when I flashed these modems but I am unable to make or receive calls. I have flashed the RIL along with the modem.
2) On trying the modems XXLS6, XXLS8, XXLS9 and XXKH3, nothing has changed and I still got the weak 3G signal though am able to make and receive calls.
I have also tried flashing a stock rom (Jelly bean) but the issue was still there.
Any help is much appreciated. Thanks in advance
As you have tried all the radios for the location already, I am not going to suggest you to do that.
However, I am interested in knowing when did the phone start showing signs of weak 3g signal? Did it happen one day suddenly or did you make any changes to software/hardware which might have triggered it?

It started happening after I switched to Cyanogenmod 11 M1. I was under an impression that the issue is with the connectivity until I tried my sim card on a different phone.
I will suggest you to flash the stock ROM or some other ROM.

Tried installing the stock rom but it didn't work.
Number one thing I also say about modems and rils, never use getril. Are you trying to flash jelly bean stock rom? If you haven't yet, try flashing it as it will also flash the stock modem too. If yes, try finding older versions of the compatible baseband firmware (or modem) and try flashing it. (Yes, you can flash older modems that originated from ics or jellybean).
