[Galaxy S II Themes and Apps] Auridran:
From what you stated in your post, I doubt it's a modem issue. Supposedly (and I take this with a grain of salt) some modems have better coverage in some areas, but theoretically if the frequency bands used by the provider are the same in both areas, the same modems should work well in both areas.

I know for a fact KH3 is capable of good things. In my basement where I get poor coverage I can get almost 10mbps on HSPA+.
[Galaxy S II Themes and Apps] rab1412000:
im from the philippines myself and i live in both sta rosa, laguna and manila. i use the kh3 modem like you and i can easily connect to hsdpa. i dont think i ever noticed the H+ on my phone but i seldom use data so im not particularly sure.

one thing is for sure though, your issues are network related and not due to modem incompatibility.

Hi

someone from Germany here?

What Modem is recommend there?
[Galaxy S II Themes and Apps] MPKO:
This can happen due to many reasons, is this normally happening only when u are at home or it happens where ever you are ?

Most of the time this kind of behavior can be seen when A or B party is on GSM coverage. In GSM system the core network and the radio network are using a different channel rates and due to this transcoding is needed to make it to "readable" for these two different sub systems. If your mobile network has lot of broken transcoder DSPs all kind of funny thing can happen and really difficult to troubleshoot.

If this problem happens only when you are at home, then the problem is most likely in the basestations which cover your area.

Cheers!

Sorry, I noticed that it you also wrote " experience the same in a noisy mall with full bars. when i cover my mouth i become more audible to the listener."

So if it happens all the time everywhere, I believe the problem is in your own hardware :(
[Galaxy S II Themes and Apps] mb:
Are you using a case? Some cases cover the noise cancelling microphone, which in turn causes echo.
[Galaxy S II Themes and Apps] mdbde:
Dial *#*#4636#*#* to acces the menu. Choose the first option and then press menu and set the radio band to whatever you want. In many cases manly the "auto" option solves most problems with the signal strength and connection issues. Tested with Vodafone in a couple of countries with several phones
[Galaxy S II Themes and Apps] jroyalty7:
Yeah it pretty much happens everywhere but only to certain people???? From reading

I tried turning my ear piece volume down and that seems to help the caller on the other end. Other than that ive tried pretty much all modems to same result. :/
[Galaxy S II Themes and Apps] jroyalty7:
Yes im using a casemate tough case has a silicone layer surrounded by hard case ill have to test that theory out....
[Galaxy S II Themes and Apps] jroyalty7:
Mine is set to gsm/cdma auto... Is that the one you were talking about??? Theres alot of options to choose from. I use my data alot though ao i dont wanna cut that off.
[Galaxy S II Themes and Apps] mdbde:
At the screen that shows gsm /cdma (or other modes!) press menu (button) I mentioned at my post. Then select radio band and set it to auto. You can try euro if you are in Europe. I'm sorry if I was not correct. Mostly auto modes solves many. But play with the settings.
[Galaxy S II Themes and Apps] jroyalty7:
Well I switched to Auto, gonna give that a try for a couple days, I will report back. Thanks for everyones help so far, hopefully this solves it!!!
[Galaxy S II Themes and Apps] sint2006:
i tried most of the modems but no luck .in my area all phones get full bars of 3g except galaxy s2 i think hardware weakness.
[Galaxy S II Themes and Apps] mbbauk:
yeh thats what happens if i fix a hard case on my SG2 echos the calls voice back to him. Can you tell me please where the voice cancelling microphone area is exactly I could cut the cover a bit to give it some open space rather than putin the cover going to waste. I was going to cut the whole back of the cover and leave the eages on. thanks for the info
[Galaxy S II Themes and Apps] Auridran:
It's on the top by the headphone jack. I'm just going to poke a hole in my TPU cases with a needle if they cover the noise cancelling mic. Not a big deal.
[Galaxy S II Themes and Apps] mbbauk:
cutting wont do any good my caseing is got cuts on both botton and upper holes and i have noticed my covering the half lower back end of the fone the with the palm of my hand the echo comes back its is something to do with the back of the fone not the holes.
[Galaxy S II Themes and Apps] jroyalty7:
Well I have to say since switching radio to auto i havent had any echo complaints from anyone but im also to busy to talk much on the phone lately lol!

[Galaxy S II Themes and Apps] ObihoernchenDE:
No. KI4 rom uses KI1 modem.
[Galaxy S II Themes and Apps] actiff:
I found the KI1 modem to have worse reception here in Australia on the Telstra Next G network (850Mhz 3G) HSPA. Speeds dropped and reception dropped also...

Sticking with KH3..
[Galaxy S II Themes and Apps] illuzi0n:
kept on getting data dropouts aswell on my telstra Next G Network, now on KI4 rom with KH3 modem :)
[Galaxy S II Themes and Apps] d3sm0nd:

Best Modem for India

Folks I need help..

I am from India. I am using Litening ROM v6.1 and I9100XXKE7 REV02 Modem. However, when in Auto Mode (GSM/WCDMA) and while on a call there is a sudden garbled tone and then the call application hangs up and finally the call drops. The garbled tone is also heard by the other party. Anyone knows why this is happening?

I have tried different Modems but without success. Can anyone guide me to a solution or to a modem which is more suited to be used on Indian Networks?

Please! I need this help quickly.

---------- Post added at 10:40 AM ---------- Previous post was at 10:29 AM ----------

Are you facing issues with Reception too? What Modem are you using?
[Galaxy S II Themes and Apps] Denwa:
So far my battery life on KI1 has been great. Further testing required though. Perhaps it depends on provider as we may be connecting on different freq bands?
[Galaxy S II Themes and Apps] Auridran:
Same here, and I'm also on Rogers.
[Galaxy S II Themes and Apps] madmack:
Here too.

KI1 is doing good with AT&T (better non-idle battery life than KH3). I'm also getting green bars for "Phone Signal" under battery usage for the first time. Oh, Wifi is significantly improved as well.

haven't noticed any difference in idle battery consumption so far.
[Galaxy S II Themes and Apps] Arijit.Ray81:
Can someone help me out please?
[Galaxy S II Themes and Apps] Denwa:
I should not, I'm on Bell.

What frequencies do they use in India?
[Galaxy S II Themes and Apps] d3sm0nd:
Looks like... for me in Switzerland KH3 has the best battery life.
[Galaxy S II Themes and Apps] Arijit.Ray81:
India uses -

GSM - 900 & 1800

3G - WCDMA - 2100

Which modem is file is best suited for this?
[Galaxy S II Themes and Apps] tudort:
Does flashing just the KI1 Modem will change my bootloader too ? I want to be able to use jig to reset counter. Thank You !
[Galaxy S II Themes and Apps] kshting:
Just go ahead and flash the KI1 modem, you would still be able to use the jig with no problem at all:)
[Galaxy S II Themes and Apps] sint2006:

[Galaxy S II Themes and Apps] landwomble:
Noob question. I'm new to the S2. Are the modem files analogous to flashing the radio on the HTC phones? I.e. they contain radio firmware updates and sometimes hardware driver updates?
[Galaxy S II Themes and Apps] Denwa:
Pretty much. replaces modem which is the radio.
[Galaxy S II Themes and Apps] shahed26:
Hi

Please excuse me for a noob question

I've got a T-Mobile UK Galaxy S2, just wanted to confirm which is the latest Modem for the UK T-mobile SGSII

Currently on new modem KI3, but the WI-FI signal strength is very poor.

Thank you
[Galaxy S II Themes and Apps] Seifer1975:
KI3 is very good for me!! I have faced the same issue with all past modems, ie after a while the modem seems to get "stuck". It shows that 3G is still connected but will not be able to download any data, until I reset the modem by doing an airplane mode on/off. Don't have this problem anymore with KI3.
[Galaxy S II Themes and Apps] cr0wnest:
Im assuming you flash these modems through clockwork recovery like how you do for HTC phones? Ive googled for this and they used a tar file with odin, however these are all in zip.
[Galaxy S II Themes and Apps] CamoGeko:
You're not 'supposed' to flash modem/radios through recovery on any phone..... HTC's have fastboot for that, which is the safest method. Same here, you're advised to flash modems through ODIN for your own good.

Extract the zip btw. ;)
[Galaxy S II Themes and Apps] cr0wnest:
Good to know, glad i didnt try it out before asking. :D

When you say extract the zip, do i take out modem.bin then flash it via Odin by selecting the PHONE option?
[Galaxy S II Themes and Apps] Auridran:
You're not "supposed" to flash anything outside of ODIN, and if we want to get technical, Kies. However, the development scene would be a pretty stagnant wasteland if all we used was Kies.

The point is: flashing modems from recovery works, just like flashing a ROM or a kernel from recovery. If recovery flashing breaks something, reflash with ODIN.
[Galaxy S II Themes and Apps] CamoGeko:
Well, I don't use KIES... personally I think its a crap program that gives me no advantages whatsoever. Unless I'm really lazy or I'm on a stock ROM.

Also, I never said it didin't work. What I said was it's not advisable to flash modems through recovery.

:)
[Galaxy S II Themes and Apps] Auridran:
Exactly. That's why other tools are used/made available. You're the only person I've ever heard say not to flash a modem through recovery since getting into the development scene with my original SGS. A lot of real developers that are also ROM cooks will include modems with their ROMs, which are flashed through recovery.

While my own experience is only one of many, I've not had a single issue with flashing a modem through recovery. In fact, I've only ever flashed a modem through recovery unless I was flashing to stock and I've yet to experience any hiccups due to it.
[Galaxy S II Themes and Apps] BenEadir:
At the risk of being totally shot down for asking a noob type question (I'm not a noob BTW) is there somewhere where the various modems are listed and their attributes summarised or even compared to one another?

I just updated from Villain Rom 1.4 to 3.0 (2.3.5) and installed the latest KI3 modem (from this list http://xdaforums.com/showpost.php?p=17967764&postcount=5) but I've no idea whether that is the best modem for my circumstances Vodafone Ireland and my preferred performance criteria i.e. excellent GSM and Wi-Fi reception plus low battery drain.

Can anyone shed some light? Do Samsung issue a development update listing the progress made from one version to another?

Ben
[Galaxy S II Themes and Apps] Auridran:
The only things you can really do are try the modems yourself and listen to what other people say about them.

Samsung does not provide changelogs.
[Galaxy S II Themes and Apps] BenEadir:
Hi Auridran,

I'm more than happy to read what others say about each modem & decide for myself, the problem is I can't find any single source where the pro's & con's of each modem is discussed.

Surely someone has tried a good few of the modems & summarised their findings in one location?
[Galaxy S II Themes and Apps] acolwill:
Modem code has no affect on WiFi performance.

Modem deals with your baseband only I.E. mobile network, 2g GSM/3g UMTS(HSPA)

WiFi is dealt with by drivers which are usually exclusive to that build of firmware.
[Galaxy S II Themes and Apps] Denwa:
In other words... try different kernels for wifi. Modems effect mobile data/voice.

Which modem work best in general KH3 or KG3 anyone?
[Galaxy S II Themes and Apps] Denwa:

Switched to KH3 and my battery usage graph leveled out. I only lost ~5% overnight..(KI3 would drain the whole battery)

After about 22 hours on KH3 with very limited phone use (call or two, market updates, roam in and out of Wifi, other misc), I've lost ~35%

I've been testing KH3 on a fully wiped phone, with nothing installed above what came with the ROM

The guy we helped on irc had a sgs style soft brick after flashing it.

So whatever recovery stuff and checksums failed... As such I suggest odin flashing modem, as it means you can recover a soft brick quickly and without having to harass people for help...
[Galaxy S II Themes and Apps] pulser_g2:
If cwm is validating sigs by default, I may look at it. But I am not too happy at the ability to disable signature verification... Signing a zip takes seconds for me to do on a 200 MB rom, so if someone can't do it, they shouldn't be trusted to release, if I'm brutally honest.

Either way if cwm looks safe enough, I'll consider it, but I have reservations in modem flashing without odin being handy...

[Galaxy S II Themes and Apps] nightranger73:
It's not meant for this and is a user option to disable it or not. It's more a remain from older update.zip from Samsung that had to be signed with their key

Good to know that.... all CyanogenMod modem have always been shipped that way since users reported different performances depending on their country... I think every report of modem should also tell from which country as sometime mobile data or even wifi get some restrictions due to specific laws about the range if frequencies.

One of the most common problem is the Canadian 850MHz range for bell users

I wrote at length about this in the previous page. Given someone had a soft brick from flashing a radio, and needed ODIN to fix it, it's not a good idea to go about flashing radios on the move...

You should have ODIN and known good copies of the MODEM to hand.

I will look at CWM and how safely it flashes, but for now it's ODIN only

i9100T Modem?

The stock firmware is already posted.

How do you extract the modem only to be flash-able with ODIN?

Downloaded the stock firmware, extracted the modem.bin and created a tar out of it.

Will this work if flashed with ODIN?

Also does flashing it, cause other data to be lost?
[Galaxy S II Themes and Apps] caudex:
Nevermind, I went ahead and did it.

Created the tar using the cygwin and tar with ustar parameters.

I have attached the original Vodafone Australia i9100T modem.

For AT&T in my area, right now KI4 is the winner.
[Galaxy S II Themes and Apps] Unclean009:
I agree here. My battery graph was completely flat overnight.
[Galaxy S II Themes and Apps] CamoGeko:
Flashed KI4 earlier, and have to say immediate impression its that the signal strength is pretty much the same which is good.

Although saying that, the battery seems to be draining slightly faster when I'm using my phone. Then again modems/radios usually need a few days to settle in/adapt before they become battery efficient.

So I guess I'll stay with it for this week and see how things go.

Please disregard everything I said in this thread about KI3.. It very well could be OK

2 nights ago, with KI4 I lost 1% overnight while last night 40% with no apps installed NOTHING CHANGED.. So I check my usage and Android OS is 70%, so I looked around and what do you know but the GS2 has a known Android System bug that keeps the device from sleeping..

without boring you with the details that is literally ALL 3 of my high-end Android devices with at least one debilitating bug/problem.. LOL!! I'm just gonna get my Kaiser out and be done with it :p
