I know this is a pretty old post, but unfortunately not all of us can afford new phones.

So when I recently bought a used S2, I bumped into these problems described. I even went ahead and bought a new battery, since I wasn't aware of the condition of the used one.

Well, after changing batteries, factory resets, flashing roms (from stock to the latest CM) and whatever I could think of didn't solve my 4 hour battery duration and overheating, I was almost certain the phone wasn't good and that I'd been scammed.

Fortunately I found this post, and guess what? Problem solved!

Thank you so much mate!

Increased the temperature

yes i have installed this modem and before this my phone was heating only upto 45 degrees now it is a t 52 degrees when charging.

im running jellybean(4.1.2) update from samsung i hope i find a solution .

thanks in advance
[Galaxy S II General] joaomarques:
Check other modem options. You must have a different modem and need a different download accordingly.
[Galaxy S II General] lohtse:
Keen to try a few of these to see which I find best in UK....what are the recommendations other than one in first post???

working links would be great too..

thank you

PS

4.1.2 soon flashing 4.2.2 incase you ask :P

not the best radio software

It seems that this radio version has worse radio for me in NL, KPN network. So i think i will install BULS1 again.

After experimenting a bit, the one working best for me so far is the KI4 (Vodafone Portugal in my case), but I've read somewhere that the BVLP7 is the best working for Orange UK, so I'd start with that one.

The results seem to vary a bit anyway, so I'd say it's mostly a trial and error method.
[Galaxy S II General] lohtse:
thank you

tried a couple and all seem ok and similar so far....one issue is when using network monitors they show signal strengths as 100% but on using one that came with rom it shows true strengths..

Any Ideas???

Can I do this on stock firmware, stock ROM, unrooted Samsung Galaxy S3 which is currently on 4.3 JellyBeans?

Is there a way to revert back if something horrible occurs such as unable to receive or make calls?

To sum OP up, just flash KH3 modem and you're done. That's what it says, if you don't want to read all the story.

salut , vad ca esti din bucuresti , acest modem va functiona si pe 4.1.2 oficial ?
[Galaxy S II General] aki2002:
This is awesome , i tried heaps of modems but all were either heating or not picking up network. I flashed KH3 and at first it did not work but i thought i should reboot, so i did and it solved the problem. My phone is no longer heating up when 3g is active.

Thanks a lot.
[Galaxy S II General] dileepasampath6:

This method worked for me... now my phone is coool... I flashed the modem.bin by ODIN with my CM 13 marshmallow rom.. thankx again. :) :D

My Baseband Version is I9100DDLS9

Would this fix work for me?

Well, I tried this one and It didn't helped me :(.

No issues tjhough as it is working for others, good work :)
[Galaxy S II General] DBachiniLima:
Same case but not work here. The i9100 continues overheating. :(
[Galaxy S II General] channel48:
will this also work on a S2 running Android 7.1 ?
[Galaxy S II General] shkedov:
Hi, I decided to go for it and check it for myself.

Just finished flashing, signal is super fine, also with 3g on (here in Israel, at Golan Telecom).

Didn't check battery performance yet, but I believe from where my battery stats were you could only go better ;)

Anyhow you can know now from me that it's tested and working to flash on 7.1!

Cheers! :highfive:
[Galaxy S II General] Xupicor:
Works under 7.1.2 (XenonHD), the phone is slightly less warm today, but yesterday it made no difference, so I'll hold on that one until more testing.

After some more time I think I can tell that it didn't really change things in the long run. The phone is still pretty hot when used, the only time it's cold is when I turn of cellular data, which helps battery life a lot. Anyway, worth a try.

Hi. I can confirm this modem is good. I had MS4 modem before and when I played 3d pool game my phone got overheated and turned off itself. With this modem only 31 degrees Celsius. Thanks.

Hi how can I restore ms2 without going back to stock ROM please? Ever since I installed kh3 asphalt doesn't work on my s2 it tells me to ask for my money back. Does anyone have the xxms2 baseband please?
[Galaxy S II General] blue whale:
you can download I9100XWLSE-2014-11-13+21-38-01 which has a modem inside and then flash this in odin, then dirty flash your current rom ???

or find the original rom xxms2 on https://www.sammobile.com/firmwares/galaxy-s-/GT-I9100/

I have read up on KI4 modem,people are experiencing problems with it,like dropped calls,3g not working etc. , probably its network related as well.

Please give me some temperature numbers, how hot is it while using 3g or wifi ..gps,how hot is it while running a game etc.?
[Galaxy S II General] rj3005:
+1

10char.
[Galaxy S II General] karendar:
Giving a modem as a fix without giving the region it's used in isn't all that helpful. For example, KI4 wasn't all that stable for me but could be for others. KH3 has horrible signal for me (Can't even place a call at work) and NELP2 works perfect, strong signal.

Trying different modems is part of the international SGS2 phone game...
[Galaxy S II General] john_x:
I have used it in England on the O2 network and on "Three" , and now I am using it in Romania , for me it was a fix..and also for 2 friends of mine,a friend of mine from italy had the same troubles with his phone..and after he got the OTA update to base band I9100XXLPS, KERNEL: 3.0.15-I9100XWLP7-CL340913dpi@DELL134#3,VERSION BUILD :IML74K.XWLP7 his problem was solved as well..he is reporting same as mine...while on 3g or wifi phone stays at 33 degrees...before it was over 40 degrees, so you could try LPS modem.
[Galaxy S II General] karendar:
I actually have a collection of many modems on my SD card, tried alot... NELP2 is really the most stable for me. Then again, I'm in the land of the polar bears (Canada) so my experience is not representative of europeans. ;)

Best thing you can do in my eyes is this:

Download every modem known to man.

Take a day off from work.

Find a spot where your signal is flaky (Best way of testing modems I'd say)

loop until modem=0

Install modem. See if signal improves, test phone.

repeat
[Galaxy S II General] john_x:
Yeah..but here is the thing..even with LPQ..the signal was great..full signal..then all of a sudden...NO SIGNAL ..but this was only 2-3 times a day and only lasted for seconds,..but the biggest problem was heating..I mean..REALLY REALLY hot :( ..now everything works great,and the phone is cool :D

probably a silly question, but im new to samsung, and currently experiencinjg this issue - Does my S2 have to be rooted to do this fix? If so, any unrooted fixes for gps and overheating issues?
[Galaxy S II General] john_x:
No buddy, you don't need to root your phone,just download the zipped archive on the first page and follow the tutorial to install it via odin ...its really easy and takes less than 2 minutes the entire procedure :D , good luck and please come back with a review and tell me if that solves your isue.
[Galaxy S II General] jinwu57:
oh boy!! - looks like i messed something up! currently at the "odin mode" screen and there's a green android on the screen and under it says, "downloading...do not turn off target!!" It's been going on for more then 2 minutes...closer to 5 mins now.

Here is what is showing on Odin:

[Galaxy S II General] john_x:
hmmm....did you load the modem from the phone button and did you uncheck the "F. reset time" ? ...if not..remove the cable..hold down power to restart your phone by keeping the power button press...then repeat the procedure,make sure you do it in the order described on the first page, and make sure f. reset time is unchecked
[Galaxy S II General] jinwu57:
after doing some reasearch, I think the problem is that I cant get into download mode. When I press vol down and power, it takes me to that Kies error message. hmmm...what should i do?

Also seems to be an issue with a the driver being corrupted?

Did you fallow all of the steps in the tutorial? did you use the "phone" button to load the modem and did you UNcheck F reset time before clicking start?
[Galaxy S II General] jinwu57:
Yes, I followed up all your steps. The first video shouldn't pertain to me since I'm not rooted and dont have cwm. I am currently in ODIN mode right now and the program seems to stop at:

Can you get your phone in to download mode?
[Galaxy S II General] koolshubh:
I think it is soft brick..

Use a usb jig.. I will force the phone in download mode and then u can flash ur prefered firmware...

If u r a noob so dont play around with ur device..

First read all the basics and how to..

And backup ur device and efa folder before playing with devicee... :)
[Galaxy S II General] jinwu57:
Yes - I can. At this point, I just want to figure out how to factory reset my device. Any ideas?
[Galaxy S II General] john_x:
http://www.youtube.com/watch?v=ksDiaKE6umk

But before you do that I think you did something wrong...did you unzip the arhive somewhere before you loaded the modem from the "phone" button? did you make sure the F reset time check box was clear?

Bellow the modem:

Follow my steps exactly.

EXTRACT THE "MODEM" FILE FROM THE ARCHIVE AND PUT IT ON THE DESCKTOP

1 With your phone disconected from your pc, get it in download mode.

2 Open odin and make sure the F reset time box is empty.

3 Press the "Phone" button and load the modem file from the descktop.

4 connect your phone to the pc

5 You should see a connected symbol when you connect it to the pc

6 click start.
[Galaxy S II General] jinwu57:
holding vol down, power, and home buttons takes me to a warning page that offers two options:

-says "A custom OS can cause critical problems in phone and installed applications. if you want to download a custom OS, preee the volume up key. Otherwise, press the volume down button to cancel.

Vol UP -> takes the phone to ODIN

Vol DOWN -> takes the phone to Kies error message.

Here is a pic after pressing Vol UP

HI

I updated my well running gingerbread gs2 here in Pakistan to ICS via auto update... and it updated it to 4.0.3.. and after the update getting the error with network signal... network signals comes and goes off again... searched on google came to your thread and did as you mentioned but the signal loss is still there...

please help me in this regard ill be very thankfull to you...

[Galaxy S II General] john_x:
Ok buddy,first thing to try , go to menu,settings,more..., mobile networks,network mode and select the "GSM only" , this should solve your problem.

If it does'nt ..follow my tutorial on page one, the user that had the problem installing it was because he had a epic 4g touch , the KH3 modem is for the international version only, it's pretty easy to install,but if you're not experiencing any heating issues..try the "GSM only" method first.

Good luck and please come back and tell me if that solves your problem.
[Galaxy S II General] ehalai:
my version is I9100 ... and did what you ever you told in there and also in your last post... i also did the gsm only thing before/after applying your patch... but it is not helping mee...

suggest me something else please... can i go back to gingerbread...
[Galaxy S II General] john_x:
Ok..so you installed the KH3 modem and you still experience the troubles you had with the stock 4.0.3 modem?
[Galaxy S II General] ehalai:
YES... :(
[Galaxy S II General] john_x:
did it do that before the upgrade? ..if yes...maybe you just have a crappy provider :(
[Galaxy S II General] ehalai:
and sometimes when I click on the Mobile Networks it gives the error

Insert SIM card to access network services...

---------- Post added at 02:08 AM ---------- Previous post was at 02:07 AM ----------

na it was quite fine before the upgrade... I even changed the sim and inserted other one from other provider... thought of this to be sure that network is ok... problem is same with both networks...
[Galaxy S II General] john_x:
I don't know what to tell you buddy :( ,try installing other modems,maybe one will work for your country better. Good luck :(
[Galaxy S II General] ehalai:
do you know some way to roll back to gingerbread please...

I'm running Resurrection Remix Pro v1.3 on my S2 and it has had overheating issues since I un-boxed it. Flashed this new modem as suggested and it cleared it right up.

Kudos and much thanks.
[Galaxy S II General] john_x:
Welcomed buddy :D ..ps ...the "GSM only" I sugested is only if you experience signal drops..but unfortunatly with "GSM only" you only get "EDGE" internet speed...so only do that if you have signal drops (that happens on most modems on different carryers ) ..
[Galaxy S II General] john_x:
With my previous radios my phone would get really hot while playing games (even if I had the internet or wireless off) ,it would get to 45 degrees,after flashing the KH3 modem...I played resident evil 4 (biohazard 4) and my phone stayed at 33 degrees celcius!!! ..and playing dead space..35 degrees!
[Galaxy S II General] TWeaKoR:
Has anyone had any problems using this with TouchWiz or AOKP ROMs? I've been running Foxhound (TouchWiz), but will be trying the AOKP one soon.

My phone's ran hot since I got it nearly a year ago, so anything to cool it down a little would be welcome! Might even manage to squeeze a few more MHz out of it ;)
[Galaxy S II General] john_x:
Well..try the KH3 modem and come back with a reply (I got replies telling me that they're phones ran hot out of the box and after installing this modem the problem was solved).

good luck!

[Galaxy S II General] john_x:
Go to market and download "battery HD" it gives you allot of information when you open it..just scrool to the last page and it tells you the temperature..also go in setings and click to show it on task bar and it will tell you how much battery you have left with numbers ;)
[Galaxy S II General] ayhamx360:

My phone 2 hours ago was temp was good like 31

Now it just changed to 36 with out doing any thing just opened vpn lol

Very Good

Thanks for the post. I've just finished the procedure by ODIN and everything was fine. I live in Italy and I have the same data of your Italian friend. I had the same problem (loss signal, over heating on the side of the camera). I download also Battery Hd and now the temperature is 35°. Actually, before to change the modem I had 33° but I have to test the modem for some days before to say that's fine. So far, I have to say that I was able to send MMS from my home where normally I don't have signal (now it's seems to be quite good). Many thanks :good: Just a question in case of problem: Where is possible to find a back-up copy of the farmer modem file?
[Galaxy S II General] john_x:
Just search for "samsung galaxy s2 modems" here on xda , right now in crappy Romania its 32 degrees celcius outside..even if the phone stays off..when you power it on the battery will be 30 degrees...it does get hotter during this periods (never over 40 degrees) but I tested other android devices and this temperature is normal.
[Galaxy S II General] jackfree1:
Temp stabilized at 33°! Fine! Using web or other apps it arrives at 41° but when you stop returns at 33° in few minutes. Other good aspect is the signal. Device find the signal fastly after you go out the elevator (with the farmer modem sometimes it was necessary to restart the phone).Thank you very much indeed.

Unfortunately, after three days testing I've had the signal loss again. Now it's fine for temperature (no more "burning" phone) but this mornig I had to restart my phone in order to get signal :( .

That's frustrating especially if you need to call urgently :eek: .

Do you have suggestions for other types of more performing modems to test?

Thanks a lot!

Are you using the same PC? From you post seems to be an error related to the port. Try with a different one (USB port). Sometime I have the same problem but when I change the usb port everything works properly. No success? Wait for more suggestions from experts. Cheers!

Prova a cambiare porta USB e a ripetere la procedura passo passo. In passato ho avuto lo stesso problema ma cambiando la porta usb tutto ha funzionato. Se non va in porto rinnova la tua richiesta e attendi consigli dai più esperti. Ciao
