[Q] Darky's Rom 8.0 - Issues with weak signal

I recently updated to Darky's Rom, 8.0, wipe edition, and although I really like how fast it is, and the battery life seems ok, I've noticed a strange issue.
I'm on Rogers in Canada, with a Bell Galaxy S Vibrant (i9000m) so it only gets UMTS band 1900.
While on the stock Samsung firmware, I'm often in an area where I get say 1-3 bars, but it seems to work fine.
On Darky's rom, it's constantly going from the 1-3 bars to no signal
In areas with good-excellent signal, it works flawlessly.
I'm guessing this is a bug with the modem he is using in this rom?
Any ideas anyone?

The modem he uses is the latest one XXJPY. Only thing I can suggest is try one of Doc's ROM's and choose the modem you had before you installed Darky's ROM and see if that affects performance. Some modems perform better for others purely because of their location (Normally Europe tbh mate). If you see better signal from a different modem on Doc's though and its a real problem to use Darky's, just make as much of a similar version or maybe one you actually prefer in his kitchen and install R64's theme ontop. Won't be much different tbh mate

Instead of flashing another rom why don't you just try flashing a new modem, in the JL2 thread found in the general section theres a JL2 modem file thats flashable with clockwork. Try just flashing the modem to see if it helps you out.

Thanks, I found it: http://forum.xda-developers.com/showpost.php?p=10188028&postcount=177
I may give that a whirl, at least to try it. It seems the general consensus is that the GPS does not work anywhere near as well with this as with the one Darky uses, but I definetly want to compare, so it's good. Thanks

That's pretty neat, I hadn't seen that before

I'm running darky's 8.0 with a jl2 modem. Just find a modem that is flashable via cwm and flash that on top look in one of my recent posts, there is one in there. Then all you need to do is manually add your access point name after you flash the modem and you should be good.

JL2 Modem with 8.0
I'm running darky's 8.0 with a jl2 modem and the signal and GPS functions amazingly. I'm on Fido (Rogers Network) and highly recommend flashing the JL2 modem to fix your issue.

there you go!
Just flash with CWM

thanks guys, i'll give it a try.
btw I did some more investigation by going through the band selection.
Rogers, who I use, uses GSM (EDGE) on 850mhz and 1900mhz, and UMTS (3G) on 850mhz and 1900mhz
The i9000m supports GSM (EDGE) on 850mhz and 1900mhz, and UMTS (3G) on 1900mhz
Using Darky's rom, GSM 1900mhz and UMTS 1900mhz are working. GSM 850mhz is NOT working, hence when I'm in an area with poor 3g signal, it is dropping to EDGE, and since I'm not getting the 850mhz GSM band, I'm dependent on the 1900mhz GSM band, which is iffy in this area

So I installed the JL2 modem, and sure enough 850mhz is BACK!
Woot! Thanks people
I'll do some tests with the GPS later and see if that is still working correctly.

Great to hear! Enjoy this awesome ROM and if you haven't already, please consider donating as Darky has put a lot of work into the creation of the ROM.

no issues at all since switching back to JL2 modem, looks like this is a must for Rogers users.
Thanks again all.

Works for Latin America SGS
Thanks for the info. My phone works very well now.

Is there a way for me to verify the version of my modem? It looks like it's working better ever since I flashed JL2 modem, but I just would like to check...

Hello everyone!
Im from Malaysia. I flashed my GT-I9000 about with Darky ROM 10.2 final which is based on JVQ ROM (Gingerbread 2.3.4) about a week ago. Everything else is great except for the poor signal strength. I suspected this could be due to Europe Modem. Can I flash my phone with Asia modem? If yes, what the best asia's modem version to be used with DarkyROM JQV v10.2?

[Q] Best modem for canadian Bell ?

I remember reading somewhere that Bell Canada uses the 850Mhz band and only certain modems support it, can anyone point me to somewhere I can download the latest or best modem for Bell Canada ?

Use either KC1 or JL2 these are the Canadian modems. Get them in rom kitchen or if your on CM7 go to Zach's thread and he has it there

How do I get the modem only from the romkitchen ? (I'm using GingerReal rom so I don't want the whole package from romkitchen)
(I remember there was an update.zip only option, but it seems gone)

Just download the modem you want from http://forum.xda-developers.com/showpost.php?p=9874879&postcount=1
They are all flashable through cwm recovery.

Thanks a lot, bookmarked it

Yeah its a shame they don't sticky the REALLY useful posts, like the above modem listing. There is another fantastic post out there with a complete list of deodexed samsung roms which is lost on the forum somewhere... I'm really sick of scrolling past 11 stickies that only answer maybe 10% of the questions on the general forum.
Anyway, I'm ranting. Glad the link helped!

what is useful is all relative...

Sorry if the thread is closed but i just dont wanna make a new thread just for this... Do any of you guys know any other better modems to use in BC, Canada other than UKG3 with 850Mhz band for Bell Mobility? JL2 and JK4 suck. anything else?

Yes it is the same as the international one.
i am able to flash any i9000 rom on my i9000m and it works fine...
I've flash darky's Roms (from 9.5 up) and now i'm currently using Dark Core 2.7.3_4 JVP running the F1 JVP V9 ROM and love it.
What did you need to know?

And i9000t = i9000?
Sent from my GT-I9000 using XDA Premium App

For GT-I9000M, any rom would most likely work, but you might get issue with the modem.
If so, do what's stated here:
http://forum.xda-developers.com/showpost.php?p=12156313&postcount=438
and you'll be able to run almost any modem

How can I find out what is the original bell mobility froyo rom? I want to reverse my phone back to bell's settings.
Can someone please help!

Bells firmware is KC1
Sent from my GT-I9000M using XDA Premium App

The I9000m is very similar with the exception being that it uses 850mhz band umts and GSM rather than 900mhz.
this is why you might have issues with the modem. International version modems support 1900mhz band so you may not notice the issues immediately as bell runs both 1900 and 850 but its best to at least flash a modem that uses what is available. Some people think the 850 band is better but unless you check to see what band is in use all the time who really cares as long as it is available.
As for the firmware. As mentioned the most current is known as KC1 which is the last 3 digits of the whole thing. You can find it at samfirmware.com (you need a username to download - they seem OK - no spam) and then flash it via ODIN (search for 1 of about 18000 tutorials here or see the one at samfirmware.com)
Good luck all.

Best Modem for Bell i9000m and ICS?

My phone is the i9000m Bell and I am on TeamHacksung v.14 and wondering what is the best modem to use?
Right now I am using UGKG3. It works but its not very strong for signal.

I used UCKG3 and it's fine on 850Mhz which is what Bell uses. To check you're on 850 dial *#*#0011#*#*
I can't post links but google 850 i9000 for instructions on how to add the 850 band if your phone isn't connected as 850 CDMA

when I do that dial this is what I get
UMTS: HOME(CS+PS)
RRC State: IDLE
WCDMA 850 band 5
FREQ DL: 1087
FREQ UL: 862
CELL_ID:*****
PSC:7a
RSCP:-101,ECIO:-10

Well you are on 850Mhz but your signal does seem low, maybe a low signal area?
If you poke around in this thread you can try other 850Mhz modems, some might work better in your location. Finding the best modem for your carrier/location seems to be a lot of trial and error

thanks rax22... I will check around.

I tried this test and it says:
WCDMA 1900 Band 2
I am in Southwestern Ontario Canada.

Same with me. I'm currently in an office with poor reception, but my settings read
UMTS: HOME (CS+PS)
RRC State: IDLE
WCDMA 1900 BAND 2

FREQ DL: 587
FREQ UL: 187
CELL_ID:0x_______
LAC: 0x2936
PSC: 142
RSCP: -110. ECIO:-14
I was unaware that flashing a different modem may improve my reception/service, I thought it was a sort of works-or-not thing. If anyone would care to help as well that would be great
(sorry to OP, don't mean to steal thread, only gain help from it as well)

Are these two showing the signal strength?
RSCP: -110. ECIO:-14
If so what do they mean and should they be higher or lower for better signal. I have been trying lots of different modems and trying to figure out what works better for me.
thanks.

You can't use anything other than 850/1900 on Bell. 850 is for downstream, and 1900 is for upstream. KG3 is the only radio that is known to work with Bell.

I tried the JVT modem today and it worked. Ran a speed test with wifi off and got some decent results. I did go back to KG3 though.
Can I ask exactly which KG3 modem file you are using? There seems to be a few different ones floating around with different names and file sizes.

I9000 on Bell here best running modem i found is KB3 fastest buy far on ICS 4.0.4 DK 3 Devil kernel 1.1.6b CFS

Where did you find that because it's not in that link that was listed here. Also, what region do you live in because that could have something to do with it as well.

nope
850 and 1900 are two different bands. Both can work both ways.

I'm using the UGKG3 , Since this is the baseband they gave me with my Bell Samsung S Vibrant, I managed to find an ICS rom using UGKG3 here on Xda. Might want to try it out.

No, it does not work for Bell phones. I already tried it and it messes up Hacksung rom badly.

[Q] Modem question

Hi All..
I have been having some peculiar problems regarding modems and was hoping someone could share some insight on it.. I get my modems here: http://soggycashew.weebly.com/index.html , and currently am on MIUI, but the same problem that I am facing persists with CM7, ICS, or any I9000/I897 roms too.
First off, I'm from Malaysia and using Celcom, thus these bands are used:
3g: WCDMA-2100
2g: GSM-900
The problem that im facing is, whenever I flash a modem that doesn't have 3g 850mhz by default, I break my 2g.
Something like this: Flash a modem with 850mhz by default (ones that i tried: UGKG3,BVJJW2,UGKC1,UGJK4), everything works fine.
Flash modems that don't have 850mhz by default (ones that i tried: ZSJPG, DXJV9, ZSJV6), 3g works fine (wcdma 2100) but 2g is broken and if i force it to "2g ONLY" i get emergency calls only. Checking the service menu, i realise that it is getting a signal from another carrier using the gsm-1800 band, but doesn't get anything from home network on gsm-900 band.
Any idea why and how to overcome this?

Hmm... Use one of the modems that work for you, and the problem is solved!

You can try looking at samfirmware.com see if there is intenational package for your are and pull our the modems then put it in a cwm scrip for cm7/ics.

Yea, that works too, but all the modems that work are not even remotely meant for my region.

Actually the modem that is used here officially for the i9000 is DXJV9 and already available and is one of the modems that I tried but is giving me the problem..
I'm using BVJJW2 for now, somehow UGKG3 heats up my phone very fast.

I have similar problem.
My cappy can use only 2G network but not 3G.
I am running on Doc's Master ICS V3.1 with its default baseband.
Is there any one facing the same problem ?
Please advise.
