[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?

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.

[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.

[Q] Can't connect to 850 AT ALL

Hello everybody I'm having a bit of a problem with my SGS i9000, international version. I'm currently running CM7 with the UGJL2 modem.
I recently signed up for a data plan. My carrier is Movistar Chile.
Problem is, I can't connect at all. Not even on EDGE. I have checked the APN settings and they're OK.
I have also tried changing the settings in Service Mode to no avail. When I choose any other setting than GSM 1900, I don't get any service.
Also tried changing some settings in Testing. Nothing.
Tried flashing many modems, most of them with 850 enabled, no good.
Any ideas?

I might suggest to flash a different modem or one of the radio 850mhz files found on this site.

I can't recall if I tried that modem. Will flash and check. Thanks for your responses!
EDIT: flashed KC3, no good. There's no way it'll connect with 850, just 1900. Tried changing settings in Service Mode, nothing.
Maybe flashing another ROM?

Try this for 850mhz
I am on Telstra in Aussie and we use the 850Mhz, and when I upgraded ROMS I had to sort out the same issue you are having. I found a Telstra modem, opened a modem file, swapped my modem into it and put it into my phone. The in recovery opened the file an it all worked. Not sure if that is the correct way, but it works for me and gives me both 850 and 2100 for Telstra.

Change your rom to jvu, its sweet, and try to use the modem that was in your stock rom from chile
Im using simplicity + semaphore+ UGKG3 modem

Thanks for the reply. Sadly, the phone was imported all way from England... not the smartest thing to do...
So tecnically there is no stock Rom for the I9000 from Movistar Chile.
However, now that you mention it, Movistar used to sell the I9000B here, and I'm not sure if I could grab the modem file from a I9000B from Chile (if I happen to find one) and flash it. Are I9000 and I9000B modems compatible?
EDIT: found out something weird. I actually got a hold of a SGS2, factory unlocked, and swapped the SIM cards. In the SGS2, the APN settings from Movistar Chile are picked up automatically (preconfigured?), thought there is still no connection when Data is enabled. This (APN settings preconfigured) DOES NOT happen on the SGS1, as if there weren't any settings predefined. I have to put them manually. Why...?
With the other SIM card (Entel Chile), both phones set the APN automatically and connect to the data plan without issue.
Does this mean there's a phone issue AND a carrier issue?
I also forgot to mention that I got rid of CM7 and flashed the latest Darky's Rom, JVK modem, 850 enabled as far as I know.

The apn issue is from the preloaded apns from the rom you uses, it happened to me no other than simplicity.
The letter b on i9000 means the region, from example im in mexico and i have a i9000t that its for latinamerica, the i9000 alone its erupean and MAY BOT HAVE 850mhz antenna
Do you had 3g before the data plan weon? Hehehe

Ohhh, so the APNs are Rom related? Interesting, I might try flashing another Rom. Thanks
I have flashed Captivate modems on the SGS and they work. Could I9000B modems also be compatible?

Dont know if i9000B have 850 MHz

It should have 850MHz, since that's supposedly the frequency Movistar uses here...
Still trying to figure out what to do

Have you tried to make sure it is enabled in the network mode/cell info/power info menu
in your dialer: *#0011#
and make sure under all the options 850 is enabled

Thanks for the reply, but I already tried that, didn't work SGS doesn't support 850mhz out of the box, which is why I flashed another modem in the first place.

Ok there's a cm7 radio zip it worked for me when I was on it ill find the link and post soon.

[Help] Network issues not modem related :( [Any ideas]

Right so heres myproblem hope someone can help,
Broke external and internal speakers on my s1 by using fm sprint app, then sent it into be repaired (local dealer not Samsung) they repaired it working fine now but since its come back , i can no longer make calls i only get 1 or 2 bars Max signal and only edge no 3g etc. So tried flashing a load of different modems in hoping would help tried from different regions no help. When i go to search for signal manually i can pick up the othr carriers in my country but it says your sim no allowed on this network but jt will not pick up my network.
Tried flashing 2.3.6 value pack csc modem rom etc that didn't help either.
Any ideas on what i can do to perhaps fix this I'm kinda stuck atm.
