I will be traveling soon. I have the JellyBean leak by izap on my phone right now... The battery life is somewhat ok, but I have network issues with it sometimes. People can't get to me even when my phone shows full signal strength. Therefore, I would like to know if there is a Modem/Ril/Rom combination that features stability and is most suitable for making and receiving calls internationally. It would also be good if the combination isn't a battery sucker while searching for network while not in range.(Because this seems to be an issue with many people :-/ )
While traveling these are my top requirements from the GS2:
Stability- no SoD or incompatibility with networks abroad.
Battery life- no battery drain while it isn't being used
GPS- quick locks in remote areas (I already seem to have a solution for this; but haven't tested it yet)
Camera- no pink spot or noise (Could you also recommend a good camera firmware for Fujitsu M5MOLS that fixes FPS issues and pink spot? -I've tried solution in every Camera issue thread I could find on the forum, but I still get pink spot)
Thanks! I'm looking forward to your replies! :fingers-crossed:
Just in case this question isn't in compliance with the forum rules, then I'll be sorry and the Mods can move it/delete it.
If it were me Id just go back to Samsungs proper stock rom/modem.Then when I come back,Id change it back to what I liked.

Thanks for the answer... But I wanted to know of a combination of any rom(stock, custom, etc) and Modem/RIL that provides good compatibilty with overseas networks and isn't infamous for draining the battery... And stable

To be honest your expectations are too high.Your wanting what everyone on here wants,and it doesnt exist.This is why were all tinkering with roms.
In some of requirements,while one thing improves,another will diminish i.e battery life.
I currently use rooted GB stock,stripped down with all the crap removed.I used to use nelp3 modem(gave best signal),but according to callers,speech was choppy.
I'm on NeatRom Lite 4.0 (JB leak), and see in better battery stats that "No or unknown signal" is 99.3%, and I have been in areas with good reception all day, so something is not right with the LS6 modem here in Norway. And I'm not sure if there is any other modem/ril for JB leak?
As for stability and battery time, CM9 stable worked great for me, so maybe have a look at that? With litle use, batterydrain where less than 10% pr 24hour on stock battery...

You can use other modems for Leaked jb but not other rils.
Leave ther ril alone and change the modem. Read through the thread for information how to change modems.
Will it not make phone reception worse if ril is not matched to modem?

No, Modem will reception will be improved somewhat but not 100 % because the mismatch.
Before the ril modem relationship was discovered people use to change modems with out any problems whatsoever.

Maybe someone can suggest a good stripped down rom for battery life,in case you arent near a charger.

I see in here that I should be using a XW modem, and not the XX in the leaked jb rom, so I better try another modem and see how it works out.
@jj_95nano You should probably have a look at the modems for the region you are travelling (2 first letters), but as that thread has not been updated since summer, I don't know if theire recommended modems are still valid...
You could also maybe check the signal strength of your provider on where your going.
I went on holiday recently where the tmobile reception was crap,and vodafone was a lot better.
*gets into a dilemma*
Just flashed the latest stock ICS 4.0.4 for my region... There are many bugs and FCs... I wanna flash GB, but the GB for my region is infamous for its battery drain. I guess I'll keep CWM Backups of different ROMs and try them out when I'm on the go. :-/
Depends where your going ^^
If I was taking my S2 over seas, I'd get a sim card for that region (could prob get one prior to travel), leave a redirect to no. on my voicemail. Then I would get a cwm flashable modem for the region & install it on the plane to destination. Rom wise, MIUI gb/ics - would be your best bet... everything works out of the box. Stay away from JB, unless you have a laptop handy, then it wouldn't really matter

Okay.. So I'm downloading MIUI and I have some modems of the places I'm gonna go to. The only problem is everytime I flash a modem there will be a Modem+RIL mismatch... But actually to solve that I can flash only one modem for the country I'll be in the longest. Let's see how it goes!

Yep I'm on a plan with international roaming... I finally got MIUI ICS and NeatROM Lite dual booted. The modems on the ROMs are matching with RIL and don't seem to be draining battery, so I think I'll stick to these.

Hi guys,
Just wanna ask any Malaysians here experiencing intermittent switching between HSDPA and 3G, with connections dropping as you please in 3G?
I've been trying to deal with this problem, but it doesn't seem to go away, so I thought it could be my Modem and/or Kernel problem.
Any ideas?
Yeah, it sounds like a modem problem. I've had the same issue. Just try a few modems and see what suits best.

There seems to be data freezing issues when on Maxis, Celcom or Digi with default KF1 modem. This problem seems to be there on all modems so far. Disabling Fast Dormancy helps a bit, but not too much.
Usually, data freeze shows an upload. You have to disable data, then re-enable data for the problem to go away. There doesn't seem to be a way to fix it.
After 1month+, I found out it's a kernel + modem thing. 3g will be preferred unless you're actively connected (saves bat), and will switch over to HSDPA if and when you're actively seeking connection (running apps/games with screen on).
I'm currently on TWD 2.5 kernel, and KF2 modem.
i tried xxki1,xxki3,xxki4,nekf1 and nekf2....Nekf2 is most stable than the others..

Also, the phone is not as warm, and it may be a little early to tell - but the battery life appears a tad better too!!

Hi Guys
daily Phone usage (approx): GSM & WCDMA Auto, Wifi OFF, BTooth OFF, GPS OFF, Display @ 35%, 3-4 txts a day, 3 hrs Music a day (Stock music player & Radio), Email & Weather - Manual sync. Apps: EverNote, Angry Birds.. 2 - 3 hrs on Google play through wifi.
Ive had my SGS2 for a week and updated to ICS 403 through KIES. Ive noticed that the battery lasts 1 day with 'Use packet Data' ON, but Battery lasts 3.5 days with Packet Data OFF.
- Is anyone else found this issue, how did you fix it.
- Is this due to UK KIES release, rather than a Clean EU version through ODIN.
- Will using GSM Only rather than GSM/WCDMA auto help.
How do you guys find it
Night
Packet data eats a lot and it always will. Of course you may use gsm only mode and it should increase battery life but the difference you have to check yourself on particular modem. This brings me to another solution - you may check different modems. now I work on LPW and it's awful, it uses battery a lot but the signal is very strong. Best results from ICS ROMs I had on LPS - signal was weak but never lost and battery usage much much lower. Some users are very happy with nelp - is seems to have everything: good signal reception and low battery usage.
Anyway, try few modems yourself, it also much depends on the area you live in, 3G network availability, home network signal strength etc etc. however you need to be aware that using packet data will drain your battery anyway.
p.s. remember also that while having packet data on the whole day many apps may work in background using internet (maybe a little bit but still) and it will also increase total battery usage.
Well, having such a phone, all the time on the net, one day of battery life doesn't have to be bad at all, depending on how much you really use it (I mean "screen on" time).

Thanks for that great info, really helpful.
Where I live (Newcastle UK), I get H+ but on 1 or 2 bars.
- Ill drop to 'GSM only' and 'PacketD ON' first for a few days and let you know.
- Then PacketD OFF.
- Then ill try a few Modems.. LPS & LPW as you suggested, and ill post back, maybe it can help others as well.
Also, Im not that keen on ICS as an OS.. always having to sign in or register online for every single thing, so
- Is it possible to go back to 236 GB using ODIN after updating to 403 ICS through KIES.. KIES hasnt locked my phone has it?.. If I can find a EU/UK 236 that is .
Thanks
Night
just use Odin and don't forget to do wipe after downgrading - it can save you from lot of troubles coming from ICS leftovers... the simpliest way is to use *2767*3855# code but remember that it will wipe all your data so do backup.
while choosing modem you may help yourself with topics like these ones:
http://forum.xda-developers.com/showthread.php?t=1277593
http://forum.xda-developers.com/showthread.php?t=1603042
you will find some tests there but you have to read "a bit" to find suitable ones.
however, if you'd like to go back to 2.3.6 you have the battery life comparision in the 2nd post of the 1st thread. still, much depends on the network conditions in your area.
p.s. i talked to some friends of mine who where comparing modems according to signal strength, Fast Dormancy support, voice calls and video calls quality. their main subject wasn't battery usage but still they have much more experience with it than me. anyway, they say that lowest battery usage they had on nelp2 and nelp3.
Im on Virgin Mobile UK, which use both T-Mobile UK and Orange UK masts, so maybe a T-Mobile modem might be ok to test.
However, in the last 12 hours since my first post, i just set to GSM Only and what a difference, and it downloads email and data quickily, but thats not definitive though.. Im still testing it.
In Network connection in About Phone, its using a network called edge:2.. cant find anything on it at all, have you heard of it.
Also, I know this has been asked before, so i do apologise, but Ive checked in both Android Development sections, which is very confusing, and cant find a clean stock EU/UK 236, and samfirmware have removed theirs.. Could you possibly point me to one please.. . I did find one online called XWKL1 INU?.
Thanks
Night
open stock ROM for UK you may find here:
http://forum.xda-developers.com/showthread.php?t=1075278
search for XEU. the same here:
http://samsung-updates.com/gt-i9100-galaxy-sii/
links are available.
about Edge:2... I have the same while working GSM only and have no idea what this means. maybe it's Evolved Edge (aka Edge Evolution)?
Edge:2 could be a samsung protocol, which would be nice for a simple 3G idea.
Thanks for the links bud, much appreciated .. ill have a look through them after my testing, but it looks like im going back to 236.. not liking ICS even without the modem issues.
Im currently on LPW.. I know you gave it a thumbs down, but ill keep you posted.
Thanks
indeed it's not so easy to find 2.3.6 open for UK, just like it wasn't released at all.

Thanks for the link, but what is a Frankenstein Rom.. In my experience there is no UK Firmware, only open EU firmware with multi CSC and you just choose UK when the S2 boots, so it can be for any EU country as long as its open, with Prefixes like "XX...", "XEU..." (i think) "XW..." .. as long as its stock.
About the test, now that Ive arrived home from scotland .. 300 miles (450km) south, I find the battery was draining quicker under LPW GSM, so I re-booted the phone and its slightly better, so something to consider.. when travelling a decent distance maybe you should reboot your phone and "Logon" to your lockal area cell/mast.
Frankenstein is a ROM made of parts of different stock ROMs. e.g. you take ROM which was released for some other region and change CSC files with the ones taken from ROM released for your region (to keep your product code). People do all kind of mixtures of kernels, modems and CSC files taken from different stock ROMs. this way you make ROM that fits you best and the same time you don't void your guarantee. Only thing that gets lost is kies/fota updates.
Talking about modem and traveling, it may be true. I live in the place on the edge of signals (one room 2G, another one 3G) and have lot of problems with home network. When I use 3G, LPW is doing great job keeping me on this signal but changes networks a lot and this way drains battery. LPS had different behavior, it was going into 2G mode in order to keep my home network rather than changing network in order to keep 3G signal. maybe the same counts when you travel - changing networks uses more battery. Anyway, there is more to it - even in 2G mode and fixed network, modem is using little bit more battery but my signal is much much stronger.

Hi all,
Just wondering if anyone can think of anything else to try to resolve an issue im having with my S3.
It is locked to 3 (UK) and runs the ALE8 firmware. Over the weekend I flashed the LFB firmware from Samfirmware using Odin, but I noticed my data speeds we're a lot slower than normal and my phone struggled to get to H+.
I decided to flash back to ALE8 but now my phone flicks between 3G, H and H+ and speed test results average 0.5 - 2 mb where as before it was constant H+ pulling between 4-6 mb.
2 factory resets and redoing APN settings hasnt worked so running out of options..... I also contacted 3 who said there were no issues in the area.
Thanks in advance :good:
If you are rooted you can try the "Fast Dormancy" app in the market to disable Fast Dormancy, it might help (not sure if 3 UK support this feature or not, if not then disabling it might help your speeds)

DDLF3 and DXLF3 are 2 modems known to fare better on most networks (afaik including Orange UK and Three Uk)
Try them out. If you're on stock, you can flash them through Odin without having to install a custom recovery.
Are you sure the configuration for Fast Dormancy is correctly configured in your phone now that you're no longer on stock?
With the stock ROM, I don't seem to be having any major problems with LFB radio.
On the plus side, the battery life seems to be incredibly good.
On the negative side, I have a suspicion that the newer radio might take longer to connect to a data connection (or perhaps re-acquire a connection when passing at speed from cell to cell). It somehow doesn't feel quite as "responsive" although the data rate (once connected) measures fine.

You don't need root to flash a modem through Odin, only if you want to flash through the phone's recovery console.
I prefer Odin.
The only hardware-related reason you might want to root is to be able to backup the EFS folder in case it gets corrupted.
(Corruption is not caused by flashing a modem)

One question aside; how old are you? The amount of 'LOL' in your posts ranges you between 12 and 16 in my experience.
No offense, just curious.
Actually I'm on ParanoidAndroid which is not Samsung-based.
However LFB is the best in Samsung's own collection since it has several battery drain fixes and tweaks (both real and cosmetical).
All Samsung-based ROM's (e.g. Omega) with some acitivity have rebased on it.
LFB being the latest and greatest I wouldn't bother searching the best of the older modems since you know you won't be able to use it for long anyway.
Just a quick thanks for the "FastDormancy" suggestions everyone. Ended up rooting my device and trying it. Worked a treat.

Hi, I tried couple JB 4.2.2 ROMs and the phone's battery drains almost 3 times faster than on Froyo. The battery of my bluetooth hands-free was even shorter. I nearly decided to buy a new one. Then I went back to Froyo and now everything is OK. On JB I installed the CPU Spy and Wakelog Detector and there was no problem. I realy want to move to JB, but I don't know how to improve the batteries' life

The kernel is usually the difference maker when it comes to battery life. I have heard claims of certain modems that extend battery life but its usually different for everyone. Most 2.2 ROMS but not all use KB5 modem, you could flash the kb5 jelly bean modem and see if there is a difference.
