Bell SGS on JS8 with JQ1 modem = success - Galaxy S I9000 General

So I got sick of bad gps, high battery drain, lots of lagging.
I was on official 2.2 JL2.
here's what I did:
- used titanium backup to backup everything
- installed the modified e3 recovery hack to allow unsigned kernels
- installed latest DamianGTO Ultimate Kernel (just a way to get ClockWorkMod) - installed using ODIN
- booted into clockwork to do a factory reset (wipe everything)
- cooked up a custom Doc's rom using all of the latest (hardcore kernel, JL8, JQ1 modem, bell CSC file, etc etc)
- installed the cooked rom via CWM
- boot up, download titanium backup, restore all important apps (good time to purge)
That's it!
GPS has improved 10 fold. Even on first boot, I got a lock within 10 seconds. It used to take 2-5 minutes!
Data and voice quality seem to be the same as before.
I'll report back on battery life, but there's no way it can get worse than it was before.
Just wanted to share, since I could not find ANY conclusive info on what does and doesn't work with Bell phones. So there you go, it works, and its worth it.

For me it's worse than JPM on CM7, battery got 4%/hour!! (2%/hour on JPM).

Do you mean JS8 or the JQ1 modem?
For me JS8 battery is worse than JS3 and not really faster.

Did you check if you still have 850? Because you probably lost it...
Sent from a phone

I still have 850, no fancy options to tweak, its just working.
GPS accuracy and lock is impressive! on par with any other gps device I have ever used. I love my phone again!
For the first time since it was new I went a full day without charging. Used gps nav lots, streamed a tv show, installed lots of apps and tried them, played some games. (I'm travelling and stuck in an airport - bored!)
The phone is really, really fast.
I have not encountered any issues yet!

Is this your first custom ROM?

So this JQ1 modem has our precious 850 band?
Looking forward to hearing more about it.

When i try JQ1 with Doc Rom, i lose my 850mhz band which means no data

Negative here on getting it so easily. Made an update.zip at Rom Kitchen with JQ1 and installed.
Usually I get mostly 850 here at work, now nothing but the 1900. Smother the phone with my hands to get it to go down from 3 bars to 1 and still no 850. Back to JL2 for now.
Check yours with *#0011# in dialer to confirm 850.

I cooked up doc's rom with the OP's recommended settings and can confirm that 850mhz wcdma does work.
maybe its related to the CSC file ? make sure you select BMC when cooking that rom.

I got data when I had JQ1 installed for a few minutes. 949/2240 on a speed test, pretty typical for a 'non-dead' time around here, I think the phone mostly uses 1900 when I'm in this office downtown office tower anyways.

I have BMC CSC. Maybe I'll try it again when I'm at home.
Might like to get a new modem working as I think reception was better with Eclair JH2 (used to get reception in work and home elevators all the way). Of course back then I had a different motherboard inside the phone too...

Franky i have had no issues JL2 since i flashed Doc's ROM. Phone and data are excellent but then again i really didn't test much before that i had Darky 8.1 and everything was normal then to.
On Darky GPS was slow took a minute or so since it was EU modem. JL2 locks in about 30 seconds whenever i turn it on, I just did it in front of my desk in the house and it locked in about 40 seconds.
I will say this whenever i flash a ROM even if using the same modem i sometimes can't get it to lock at all even after 10 minutes it will not lock. The way to fix it is to clear the GPS Data using SGS Tools > Secret Codes > GPS - Test and Setting > Delete GPS Data > close GPS >Start it Again > Get Position TESt
I just clear the Data 2 -3 turn off GPS, reboot the phone > turn on GPS and do a test that way you get the most accurate results from a cold boot. This is part of my regular steps to do after flashing a ROM weather it helps or not it has never failed me once.

yeah not sure why some of you are not getting 850, or why you would have no data.
Is it maybe area specific?
Maybe if you are in an area that has no 850 coverage it will not show?
I installed in Toronto, it worked, I flew to Vancouver, it still works...

I second that..I'm in Toronto and have flashed every kind of modem you could think of and data was never an issue. I did end up with only 1900 sometimes but there is a way to go into your phone and set it to 850 just can't remember the code......its in xda somewhere

Same here, never had an issue with data in Toronto

I've also found a way to fix the GPS, using the romKitchen (romkitchen.org if you want to find it) I was able to build a custom rom that worked very well with the GPS, I'm actually testing battery life today after a full charge. I used the XWJS8 base rom, with the hardcore kernel and the jl2 modem with the CSC as BMC..

Setting or checking 850 Band
Hi Guys,
There are a few ways you can set the 850 band; Secret codes, SGS tools, SGS Info etc.
The fastest app is SGS Tools; open this app and select the first option of Secret Codes, then scroll down to "Band Selection" if you select this it should bring you right into the Band Selection menu.
You now need to select [2] WCDMA BAND[*], it should then bring you to the next screen where you need to select [1] WCDMA ALL and then press Select WCDMA ALL BANDS[*].
Back out of the menu and then go back into it. Now select [2] WCDMA BAND[*] and you should see a[*] beside the 2100 / 1900 and 850 bands.
I hope this helps

You'll also have to disable all the others in order to have the 850
That's probably why most rom won't work "out of the box", as they have 900 enabled instead of 850

Tesltra ROM Flash

I have been reading mixed views about whether the the T9193 loses 850mhz compatibility once a cooked rom has been flashed to this model. Some say they lose the nextg connectivity and registry tweaks are required to fix this, whilst others say it is simply a hardware issue and that any rom can be flashed, keeping 850 connectivity. I bought this phone purely for its 850 mhz ability, but i hate the telstra bloatware. Can someone please confirm this for me.
Regards Romeash
I have a Telstra HD2 and use it in the US on AT&T 3G(850) with NRGZ28's rom without any problem. HSPL and ROM were the only changes I made.
Brad
where are you australia
my t9193,running v1.50 ozrom and 2.08 radio
there is a telstraband cab floating around that puts all the 850 setting back in the phone
works a treat in hobart
Yeah I've flashed several times and played with the band settings in registry. Changing the band frequencues in registry didn't make any difference so don't worry about it.
Radios did make a difference
I flashed to this ROM- RUU_Leo_HTC_WWE_1.66.405.2_Radio_CRC_Signed_15.32.50.07U_2.07.51.22_2_Ship
this got rid of the telstra stuff and seemed to give the best reception

Yep, I can confirm that too. I kept the Telstra ROM on my phone for almost an hour and a half before I got sick of it and flashed to something better. I have had no problems at all with connecting to HSDPA (and I've tried at least 5 flavours of cooked ROMS, and 6 or 7 different radios). Radio 2.08.50.08_2 works best for me, with full reception bars all the time.
The registry fix allows the 850 band to be displayed in the band options, but this is purely cosmetic and has no affect on the phone's ability to sync with the network. I haven't encountered a single problem despite numerous (and for a while daily) upgrades, so you shouldn't need to worry too much.
I would definitely recommend sticking to the HSPL and flash-overoUSB route though - much easier to recover if anything does go wrong during flashing.....
thanks alot guys, much appreciated. now i know i can go through with the flash. first i gotta get it repaired under warranty. the audio manager keeps crashing every time i try to play music through the music. ive used different micro sd's so i know its definitely not the cards. must be the phone.

Just fyi... the first two steps are wrong. If you put the phone on download first and then open Odin it will not see the phone. Just figured I would throw this out there in case anyone tried it and couldn't get it to work.

1 - yup
2 - weird

1 keeps happening, 2 and 3 haven't so far
Can you give a quick intro on the first thread about what the JPK modem is and how it compares to other modems.
I tried this in place of the jpm modem that I had with the i9000 rom I put together with the reorient kernal a few days ago and it seemed almost identical to the jpm modem. But with jpk, all bands are enabled by default unlike the jpm modem. Everything else seemed identical to jpm like signal strength and weak signals where I would normally have a decent signal. Other popeople may have better luck, but it just seems so far I haven't found a hsupa modem that matched the quality of ji6

ya its weird with these modems, it like all or nothing even with all the same bands as ji6. its like when there is data, its blazing fast, but then i can move 10 feet and have no service or data when my wifes captivate will have full bars and 3g. its almost like its a band switching problem but around my house i get the same band almost all the time so it shouldnt be switching so i dont know. im starting to give up until theres a better modem released.

This is incorrect.
You dont get all bands by default chose automatic then go to select band and 850 will be removed.
also JI6 fc'ed when it gets a data conection.
is it because i am using it with the i9000 fw.
anyone with cog beta 9.1 how is it?
does it have the same problems we have with the reorented kernal and i9000 fw

When I flashed jpk, all my bands were enabled. Which is why I said unlike jpm. I know that on jpm 850wcdma is not enabled. You cannot use ji6 with reorient kernel or an i9000 rom it will soft reboot everytime the data connects. You have to use something like jpk or jpm or or of the other hsupa modems

Ok, I just updated from Tayutama's 1.0.2 with the JPK modem to 1.0.3 by the patch.
When I first flashed this rom the 850 WCDMA was not selected in the Debug service menu. I went in and activated the 850. This was the JPM modem.
Earlier this week I flashed the JPK with Odin and checked the service menu and 850 was active.
Tonight when I flashed the update JPM was reinstalled through the patch and in the service menu 850 was active.
No real point just an FYI
i get a better signal with jpk instead of ji6/jpm....plus i have to use it lol
I've had no luck getting any of these modems to function with GSM 850..
WCDMA works but no GSM, and in the mountains GSM 1900 sucks at best.
There is a fix

This problem vexed a bunch of us, but was solved about a week ago. Follow these instructions: http://forum.xda-developers.com/showpost.php?p=8833581&postcount=165
We don't know why it works, but it does. You need to start fresh with the JG8 modem, verify 850GSM is working, then build your desired configuration from that starting point.

I9000M Randomly shutting off

Title: Why my Galaxy S locks up?! (Comatose Syndrome on going investigation)
Section:Galaxy S i9000 Q&A
Basically limits reception to only 850 band. I have not comma'd since and have not IMO lost any reception quality. And it is reversible if it doesnt help.
My i9000M on JH2 does the same thing when I go into strange buildings that are likely shielding the signal, movie theaters, parkades, basements. I can predict when my phone will crash it's so consistent, but if I'm not in any signal attenuating areas my phone is fine for weeks without crashing. I'm in Calgary, I will try the "limiting to 850 band only" trick and see how it works:
1. on the key pad, type *#2263#
2. Select [2] WCDMA BAND
3. Select [5] WCDMA 850 (FDD V)
If the [] have a star in it [*] then only the 850 band is working methinks
Click to expand...
Click to collapse
If that doesn't work or I find my reception sucks, I'll work up the courage to try the experimental [BETA] SuperPower app and turn off 2G or something?
My phone crashed in the same places the same way before I did OCLF and root, so I doubt the lagfix is responsible for this; except maybe your phone is now faster and therefore finds more opportunities to crash?
Thanks, ill give those a try. I believe the lag fix was a seperate issue as the phone has been otherwise free of those smyptoms since I un-rooted.
After reading the posted thread, I've decided to disable my email (i use the gmail apply anyway) and keep wifi off. Ill test it for today and report back.

Update yor Bell to Froyo With Registery Patch!!!

I was suffering from lack of information before I upgrade to froyo through Kies with reg patch. I was afraid of the modem file that JPO has (850 band concern and compability issues) with Bell Sgs.
I had enough with their lies and delays so I upgraded my JH2 to JPO using the latest Kies with reg patch. Everything went smooth and easy.
Although Kies gave erors saying "upgrade unsuccesful cant connect to phone" (something like that i dont remember exactly) during the upgrade after the phone went to download mode. Basically whay happened was, I was clicking the upgrade button in kies then kies was downloading files and binaries. After that phone restarts with download mode and then installation aborts. If u face with this.problem just foctory reset the phone and try again. Unfortunatelly have tried like 4 times waiting kies download binaries in 15 min each time.
I would like to say to people who is waiting for stupid bell to release froro its been 2 days now and I am running JPO without any problems. 850 band is still here and everything works like its suppose to.
If u would like to upgrade with reg patch I reccommend it. But i have to say Do at ur own risk!!!!
what settings did you use for kies? and by chance do you know what date your phone was made? i think it says it on your battery and on the phone behind the battery

Use doc's 2.2 JPO. ROM.. it works way better then any stock ROM and its safer then the kies REG hack. everything works with this rom.

Agreed. Also I don't know why these threads keep talking about the 850 band. The band is decided by your hardware, and I have never hard the 850 band not work in any ROM. If 850 did not work I would not even have coverage because Bell is only 850.

That's a new one on me. Every thread I've seen about Bells frequencies indicate 850 and 1900 wcdma(HSPDA)
Also I thought when the phone shows 3G that's 1900 and when it displays H that's 850?
Of course I'm no tech guy so I'll let someone else dispute it with facts if they have them.

Losing the 850 Band is definitely real, It's happened to me twice and had to flash back to JH8 and select the BCC CSC.
Nope. It didnt happen to me. I updated via reg patch.
I upgraded with the registry patch yesterday. Worked fine until I tried to root. Screen went white, phone rebooted but not past the animation. Get an "E:Can't mount /dev/block/mmcblk0p1" error when booting into recovery. Looks like the internal SD is fried.
I'm going to bring it in to get repaired when I get home, buy a Desire Z and sell the Galaxy S when I get it back. I have no doubt that any fix will just be temporary.

Possible fix for data stalling issues some of us are having.

Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.

Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.

That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .

I will have to give this a try and see how it works, thanks for the share.
I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!
would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well
Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .

Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.
Just been out and about and tried that setting, didn't make much difference unfortunately
Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

The wife is on Giffgaff so I think I'll give that sim a try before I get my PAC off O2.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio
confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio
Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!
I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.
Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.

Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?
