[Galaxy S I9000 Q&A, Help & Troubleshooting] mchud:
Might have a 850 fix for you. Would need someone else to try (particularly if you are on Bell, because I am on Rogers...).

Also, it should probably be noted that "my" issue was slightly different. I could connect to Edge at 850, but not 3G.

I recently upgraded to XWJM8, XXJM4, BMCJH2 and my 3G connection seemed fine. Then I flashed on DocRamBone JM8 and thought everything was good. But after this rom mod it seems my 850MHz was lost. I know it was after the rom mod update because I did a nandroid right after the JM8 flash and if I revert back to that all is well with my 3G connection (only 850 available where I am). Had no idea what the *^&% was going on.

I found this thread and at least then saw a ray of hope to restore 3G 850. I started downloading the JG8 firmware, but while I was waiting I started poking around in the dialer codes.

GSM status (*#0011#) shows as expected: GSM850

Then I started poking around in Band Selection (*#2263#). It was set to "[1] Automatic". I noticed though when I went into "[2] WCDMA BAND" that all of the bands were selected except "[6] WCDMA 850". When I tried to select this band it says:

MENU NOT EXIST

PRESS BACK KEY

Current Command is 187226

wtf. That is the one band that I need turned on! Well, when in doubt, start options surfing... I went into "[4] COMBI BANDS" and lo and behold found that I could select "[8] WCDMA 850" in this menu! Surfing on back to the main menu and going back into "[2] WCDMA BAND" showed that now "[5] WCDMA 850" band was now selected. Notice that it is [5] and not [6]?? Some kind of bug up in there which is no doubt why I was getting the MENU NOT EXIST action earlier.

Anyway, basically instead of selecting the default "[1] Automatic", I found that just going into the COMBI BANDS section and selecting everything seemed to do the trick for me.

If this doesn't fix your problem, then it sounds like maybe I was having a different issue and I will post this as a new thread...

EDIT:

I take back that it was poor DocRambone's rom mod that broke my 850. It seems like it is the new:

Settings > Wireless and Network > Mobile Network > Network Mode

setting that messes it up. At some point I must have gone in there to lock it to 2G-only. Then setting it back to "auto mode" (sound familiar [1] Automatic?) doesn't give me WCDMA850...
[Galaxy S I9000 Q&A, Help & Troubleshooting] Redth:
anyone get further with this? I tried applying one click lag fix and now have this issue...

If I look at the servicemode, i see GSM850, but I get no 3g, only edge (i'm using rogers).

This started right after the reboot after i installed one click lag fix... I'd really rather not flash an old firmware to fix this...
[Galaxy S I9000 Q&A, Help & Troubleshooting] mchud:
did you read the post above?? i believe it is the same problem you are having, and on the same network. maybe it was too lengthy as it tells the story rather than come right out with the solution:

*#2263#

"[4] COMBI BANDS"

select every band (or you can just pick the Rogers relevant ones if you want to get fancy...)

btw: anyone with a Bell plan with the 850 issue try this??
[Galaxy S I9000 Q&A, Help & Troubleshooting] Inios:
For all those that want to have the full bands using the original JH2 MODEM and CSC, here you go!

I've extracted the MODEM and CSC and created separate ODIN packages for you to use.

UGJH2: MODEM, CSC

I tested the above files by first fully flashing to JM8 PDA + JM4 MODEM + JH2 CSC and confirming the COMBI WDCMA 850 was not enabled (900 was as experienced by most users of this thread). I then performed a full reset and reflashed once again to JM8 PDA + JH2 MODEM + JH2 CSC and can confirm that the 850 band is working with the above files.
[Galaxy S I9000 Q&A, Help & Troubleshooting] AllGamer:
just for reference guys the fastest way to confirm 850 data on 3G is to type

*#0011#

then take a screen shot before it switches to something else :D
[Galaxy S I9000 Q&A, Help & Troubleshooting] testulous:
That doesn't look right. I tried it, and mine said I was on 1900 band 2. Then 20 seconds later, it changed to 850 band 5.

What if 1900 is pretty good? Would it still indicate 850 is working?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Inios:
Yes, the phone will automatically detect which band is the best based on your location.

Since I work/live in an area with a 1900 dead zone, 850 is usually the best band for me.

The only real way that I could check if the 850 band was enabled was to use:

*#2263# -> COMBIN BANDS []

If WCDMA 850 (FDD V) had a [*] this means that 850 is enabled. If not, then 850 was not enabled for you...
[Galaxy S I9000 Q&A, Help & Troubleshooting] cloudrainstar:
You can also confirm the long way by going to band selection (*#2263#), choosing [2] WCDMA BAND, then choosing a band you don't have first ([2] WCDMA 2100 or [4] WCDMA 900 for me), then hit the menu key and back, and your cell signal should disappear after a few seconds.

Then reactivate WCDMA 850 Only by using Menu Key, choosing Select, and typing 5, and hitting ok, then menu key and back.

If your cell phone reconnects after a few seconds, then you have 850mhz (You can also end and check *#0011# at this point).

If not, then you should flash the JH2 modem + csc to get it back, or go back to JG8 and follow the instructions on the first post.

If you do have 850mhz working, you can reactivate your 1900mhz (and 2100mhz too) through either [1] Automatic or [4] Combi bands.

[Galaxy S I9000 Q&A, Help & Troubleshooting] Inios:
My original post was referring to checking if the band was enabled (software) not actually enabling the band.

I found that with modems such as jm4 the 900 was enabled and 850 was not as this package was meant for	EU. While enabling 850 did work, it was not consistent and I would lose 850.

The best experience I've had was to flash a jh2 modem and csc and no changes were required to enable bands.
[Galaxy S I9000 Q&A, Help & Troubleshooting] lgkahn:
so if you have jh2 modem and jh2 csc but jm7 or jm8 pda.. you dont have to go into the menu and enable 850 every time you boot? because that is a pain in the a..
[Galaxy S I9000 Q&A, Help & Troubleshooting] Inios:

So if I understand correctly, I'm currently using XXJPK (froyo) and I dont think my 850 is enabled. Is it possible to flash an older CSC and Modem and retain my current PDA?
[Galaxy S I9000 Q&A, Help & Troubleshooting] xxgg:
Oh wow. this was frustrating!

I have a Bell Samsung Galaxy S Vibrant unlocked/rooted running XXJPK Froyo on Rogers Wireless.

Everything was working perfectly, 3G/H connection was great until... I went to Mobile network settings >> Network mode. It was set to GSM/WCDMA Auto and I have never touched this setting until today. I wanted to see how this phone perfect with EDGE/G, so I selected GSM Only. Sure enough phone connected as EDGE and everything was well.

Now I selected the GSM/WCDMA auto thinking that it would go back to picking up 3G/H network. But nothing would happen! I rebooted and all that... still same.

Phone was totally stuck on EDGE only.

*#0011# service mode show as 'GSM850'.

So after reading about *#2263#, I gaved it a try and like others have said WCDMA 850 was not selected when looked under line 2,

So I went to line 4 (combine?) and selected all, yet nothing

I tried WCDMA 850 only, I got signal but no data 3G/H.

Tried WCDMA 1900 only, wow it worked! great! but I would only be on 3G network, so from line 4 combin, I selected WCDMA 850 & GSM 850/1900 aswell.

All of sudden, I am back to square 1, I got signal but no data, not even EDGE.

Long story short, after being frusted because same setting would sometimes work, than next minute I changed something and go back to working setting, it would not work again. totally pissed me off, nearly pull out my hairs.

This service mode seemed to be... welll not so consistant? buggy? or something.

After repeating same settings, crossing figers over and over for like 4 hours...

All of sudden one of the settings I tried worked! I selected all GSM bands + WCDMA bands of 2100,1900,850. Setting held. I said screw this, it's working now and I am not touching anything anymore!

Unlike previous random act of setting not being held or data failed to connect after reboot of the phone. This time it is all working, I surf'd around, rebooted phone several times, took battery out and everything to make sure. It seems to be back to normal now. Thank God.

Sorry for if typing so much & if you can't understand what I am trying. I was just so frustrated, it's 3AM in the morning now after 4 hours of messing with same thing over.

===

Once again, never gonna touch that Network mode option again.

I wonder what will happen when I goto area where I only get EDGE and phone auto connects to it??

Will it come back to 3G onces in 3G coverage area? or stuck at EDGE again?

I will experiment and report back.

When I originally flashed Froyo my 850WCDMA worked fine because I flashed it in an 850WCDMA area. I then went to my friends house and in his area it's 1900, so I automatically switched to that. When I went into his basement, I lost all signal and couldn't connect to 850WCDMA. However as soon as I went back outside, I was back in service, but only on the 1900WCDMA band. It was only after I did the UGJG8/CSC trick that my 850WCDMA started working again.
[Galaxy S I9000 Q&A, Help & Troubleshooting] xxgg:

Nothing to do with hardware, right?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Electroz:
Yes, it is because the Canadian I9000M uses 850MHZ WCDMA and the International version CSC and Modem you flashed does not. However, there is no Froyo modem available that supports the 850 MHZ WCDMA band and the CSC has to be installed a certain way so it's tricky to get working correctly. Our best bet right now is to wait for an I9000M Froyo update.

Give it a try. Losing 850 frequency is not a big conserne for every one untill you try it. I haven't lost my signal or seen any diffenrence since I'm on 1900. I think that in most of the region you have both of 850 and 1900 and only in some place you can only rely on one of them.

just flashed JP6 on i9000m and lost 850. It's not worth it - I tried everything in this thread, #*2263, selecting all bands, etc and it doesn't help.

FYI: the Nordic JP6 does not work with 850.

I also had to enter all APN settings, using the Bell instructions for the Nexus One except for using inet.bell.ca instead of pda.bell.ca (which doesn't work - maybe because of missing 850?)

So warning to all, do not flash to international i9000 Froyo unless you really don't want GSM850 as an option.

I have NOT lost 850MHz. Phone connect just fine to either 850MHz & 1900MHz.

*I am sure about JPM or JP6 as I have not tried those*

And I don't want to touch the Network Mode as that might trigger it to lose 850MHz again. It is currently on it's default AUTO.

I'm in the same boat as you guys....I just finished reading the threads here for an hour before coming to this post, which has solidified my concerns! In the past, flashing ROMs on my other phones has always resulted in SOME sort of small problem somewhere. I don't even care about stock, I just want my phone to run bug/glitch/problem-FREE!! I came so close to pulling the trigger today, but after reading the many many posts, and the one above too, I will hold off as well until it comes out officially over Kies.

Also, a question for you guys: I haven't updated through Kies at all yet, so I'm still on UGJG9. This shouldn't pose a problem when the official 2.2 update comes, should it?
[Galaxy S I9000 Q&A, Help & Troubleshooting] tylerham:

[Galaxy S I9000 Q&A, Help & Troubleshooting] cloudrainstar:
If all you cared about is the 850mhz and don't care about your CSC being shown as Unknown... Then never flash the CSC. If it's a combined PDA/Modem/CSC, remove the .md5 on the file (if it has one), open the .tar file with 7zip, remove cache.rfs and dbdata.rfs. On your first boot, your phone should go into recovery, just select the "reboot now" option. This always worked for me with 850mhz.

Just my experiences :)

Note: If you're flashing to a Froyo version and your phone can't boot up, use recovery 3e to do a factory reset, recovery 2e doesn't wipe dbdata.

Another Note: A lot of people have a corrupted sd card after flashing to Froyo, so only flash if you're brave enough (or are confident in being able to get your phone repaired via warranty!)

Thanks for the advice. Is there anything else in cache.rfs or dbdata.rfs that we'd be missing out on by not flashing them or having the newest ones?

Some notes from my recent flashes...

For the I9000m specifically the modem hardware.

If you flash a firmware and lose your 850 band just flash the JH2 modem file via Odin, no partition and of course no pit.

If your using the JH2 modem with a froyo rom you may break some of the communication between the PDA and the modem which will report in 100% no signal in your battery stats. This may cause extra battery drain etc, but it does make a very functional combination.

After flashing to the JH2 modem you should first set the network bands to run in automatic mode in the band selection menu. That seems to refresh the band availability list from the modem software to the modem itself. If you don't select automatic then it will still report the same "MENU NOT EXIST".

I've tried this twice after a flash from a modem that didn't support 850. Upon going into the menu and looking for the 850 band it wouldn't work and wouldn't even show. Once I cycled the automatic mode though the 850 band showed up. I never had to flash any modem other than JH2. Use SGS tools, go into band selection, cycle automatic mode, then go into WCDMA and you will see 850 * again.
