Its really up to you mate....I would suggest that you try both for a reasonable period and compare results to see which one suits your needs best! And yes I believe you can flash via mobile odin and no you do not need to wipe data/factory reset.

Im running kh3 modem bt still my phone heats alot.

Rom: omega v24

Kernel: Philz.

Actually my gs2 has china made lcd screen..is this the problem for overheating? As the upper part of the screen is heating alot as well as the camera part. This china made display has overcontrast and oversaturated screen than the original gs2 display and thats why I think the heating is more..I want to make sure that is this the problem for overheating or not?

Btw, I want to add something..I dint changed the display myself as I had purchased this phone from a guy and that moron had changed the display from original s2 display to this chinese bull**** display.
[Galaxy S II General] Xp3RTUL:
u should give a try to an official stock firmware (ex: ls8 nordic countries) rooted with syiah kernel 6.05b+... no bugs, battery lasts long. also, u should keep disabled the 3g when you're not using the internet, beware of using live wallpapers etc, stuff like this, so your battery can last as long as it can. good luck ;)

yep. i suggest flashing the official 4.1.2 from poland ( xxms1, xxls8, xxms2, xeo). then root it with syiah kernel v6.05b+ then apply the kh3 modem so you get rid of the heating problem. if need help, pm :)
[Galaxy S II General] bogdan1980:
With default kernel, phone goes up to 72c.

With Dorimanx 8.14(super stable) or 8.40, we have limit at 68c.

4c mean alt, for people that like colder.

You can flash KH3 directly..just follow my tutorial on the first page,if that seems complicated you can do a youtube tutorial search for flashing a modem.
[Galaxy S II General] tutsipoppy:
One query before flashing...

Ok, this thread was exactly what I was looking for since a long time.

I hate the "Gingerbreadish" look of the official Samsung LPQ ROM so I'm currently on "Hydra H2O v1.1.2" AOKP ROM (http://xdaforums.com/showthread.php?t=1403044).

So the obvious question is, can I flash this modem on this ROM without worrying that it will soft-brick my phone or I won't be able to send SMS/MMS as posted by some of the users?

Thanks...
[Galaxy S II General] scayre32:
Cheers

I use my phone constantly, and anything to stop it overheating and sapping battery life is definitely appreciated.

I've not tried sending an mms yet, but everything else works fine. Running Resurrection Remix 1.8.1

Tryed it and I see no improvement. In fact I believe my phone heated more with this modem. Went back to LP6. I'm on WanamLite.XWLP9.V11.3 with Siyah kernel.
[Galaxy S II General] sorg:
My phone gets hot when i play games (not heavy games actually, but some puzzle). Even limited to 800mhz it still gets hot very much. I don't think modem is a source of heat. And of course flashing KH3 modem doesn't solve heating issue.

Probably, if you download a lot, like streaming video, then modem can add some heating, but i think for most people with normal usage it's not noticeable.
[Galaxy S II General] john_x:
Have you tried flashing the modem?

If it wasn't for your post and link my gs2 would have been in the bin.

After flashing a kernel I lost baseband. Tried all over the Web for a fix, none worked. I flashed this with mobile Odin and it was a success. Restored my signal and 3 UK network.

As a huge bonus battery life has really been extended and heat is not noticeable whereas it was before. Thanks again.
[Galaxy S II General] Code SyGma:
So I should flash the KH3 modem? I am on Jellybean 4.1.2 Stock. Baseband is I9100XXMS2. Firmware is JZOI9100XWLSW. I bought my S2 on Wednesday which was on already jB. And from then I have been experiencing overheating and huge battery drain.

Thanks. (Not Rooted btw)
[Galaxy S II General] solom2u2:
I've followed the instructions of the first post, and wow! .. the change from my LPS to the KH3 modem made a huge difference.

My GS2 used to go around 52c battery temp, and 62c cpu temp. Now battery is about 26c idle, 35c while browsing, and cpu is around 35c idle, 46c while browsing. I've never felt my GS2 that nice'n cool in my hands before!

[Galaxy S II General] TigerTrader:
Back to square one!

Initially loading the KH3 modem worked like a charm but over the past few months I have had poor battery life, overheating (up tp 46°C) and problems connecting to the internet.

The device connects to the router but is unable to browse the internet most of the time.

I travel a lot so this is a huge problem since I lose comms with friends and family for days at a time.

I went back to the instructions on page one to try re-install the modem but came across another issue!

When I press and hold Vol down+menu+power buttons I first get a screenshot(!!!) and then the simply phone reboots normally.

It does not give me the choice to go into download mode. I am therefore stuck.

Any suggestions will be most welcome. Thanks guys.

[Galaxy S II General] Squaredot:
But you have to press vol down + menu + power with the phone OFF. Does this make any sense?
[Galaxy S II General] TigerTrader:
Perfect sense - what doesn't make sense is that it does NOT put the phone into download mode - it simply reboots!
[Galaxy S II General] yodaco:
In my experience with s2s overheating its down to a number of things that really differ greatly between different roms and sub versions of the s2, ie v1 v2 v3 etc etc, if u find your s2 is overheating all the time i suggest you consider replacing the charger port its cheap and pretty easy to do, but it solves alot of heating issues with s2s for me
[Galaxy S II General] Xp3RTUL:
so... i have great news.

-if you want your s2 to have a 2 days battery life and get rid of the heating problems.. in 10 steps, here is what you should do:

1. flash last NEE nordic countries rom from sammobile.com/firmwares using the right pit file (we need it to format everything)

2. flash the siyah s2 kernel v6.05b

3. go to recovery-wipe everything: data factory reset, cache and dalvik, but not the battery stats yet.

4. turn on your phone

5. format internal and external sdcards

6. drain your battery completly, untill it won't turn on again, no matter what.

7. plug your phone to the network charger

8. leave it charging to 100%, but don't disconnect it before 6hours or more than 8hours.

9. when it's 100%, go to recovery-advanced-wipe battery stats.

10. reboot phone. repeat the 6,7,8 steps for 2 or 3 times.

(PS: i didn't use any of other than stock modems...)

---------- Post added at 08:51 PM ---------- Previous post was at 08:46 PM ----------

at noº8:

*8. leave it charging untill 100%, but don't disconnect it untill at least 6 hours have passed. Also, don't leave it more than 8 hours.

Flashing a pit is not recommended.. and no matter what we do.. we shall never have 2 days screen on time.. it hardly reaches 5hrs :/
[Galaxy S II General] Xp3RTUL:
this is what i have done. all those steps. i can gladly say that my phone's battery revived. i also flashed pit (it re-sets the partitions-emmc, sdcard etc). i'll post some screenshots tomorow. and also, i say again: my battery is holding up to 36 hours (only under some circumstances, a very light usage-only sms and phone calls. up to 18 hours with wifi/3G data conection, medium brightness level and other)

sorry. noob here.

can i flash this to baseband version i9100xls8? I not sure if my i9100 is international version. It's from Singapore.
[Galaxy S II General] jloh84:
The model number I9100 is the international variant of S2. Whereas the other version numbers are, for example, M250S or K (Korean version), T989 (T-Mobile US) SC-02C (DoCoMo Japan), the HD LTE version and a few other North American carrier-specific variants.

[Galaxy S II General] DS-1:
Is it possible that a "bad" modem software can overheat the phone and make stop working the back camera?

I have the NELS1 baseband (it's for the 3 italian mobile operator) on my I9100 and the phone starts overheating after 3-4 minutes from the boot.

After 15-20 minutes, the camera stops working.
[Galaxy S II General] cowbutt:
That sounds like media scanner updating. Check your internal "sdcard" (and external, real sdcard, if you have one) for filesystem errors and fix them if you have them. Then just let it run (preferably whilst on charge as it can take some time; 2h with the 64GB card I have in mine).
[Galaxy S II General] DS-1:
Thanks for the reply!

How can I find filesystem errors? What's the best way to find and fix them?

The most important thing, now, is fixing the camera issue. I've tried the KH3 baseband and it seems to fix the overheating but not the back camera problem.
[Galaxy S II General] cowbutt:
Run fsck.vfat on a Linux PC, or chkdsk on a Windows PC. Or, just backup your files, verify, format, and restore.

If I remember correctly, the camera won't work properly whilst media scanner is running. Leave it to complete before trying it. Don't try to pick a new notification sound, use the camera, or use the gallery whilst it's running as it'll cause media scanner to restart its scan from scratch. If media scanner never finishes (i.e. it runs for more than 2h or so), try stopping the media storage app and gallery, clearing their caches and data, then rebooting (which should force media scanner to start from scratch). I'd suggest doing this whilst your device is on charge overnight.

i would sugest flashing a new stock rom, found on the sammobile.com (official samsung site for firmwares and others). the one i have chosen is the last firmware released from the nordin countries region (NEE, not DNF). it is not branded, it doesn't have bugs, and works well on all regions, not only in the nordic countries (i am from romania, so... i can guarantee). if you want root too, you can use siyah kernel 6.05b or phils kernel. if you give it a try, let me know how did that work. ok?
