(rom)i9000xfjm6

I have been testing I9000XFJM6 and with this rom you can lock onto more then 8 sats. This is the first time my captivate has worked as good as my evo's gps. If the gps start acting up ater a few days use the clear gps datat trick to fix it. This is what I did to get it working.
Loaded I9000XFJM6 rom(I used CSC_I9000DBTJM1.rar for csc)
Then load Stock Captivate kernel from here and use 512 pit
Then follow this guide and use method 1 then 2. I enabled skyhook as well.
If you have any market issues try wiping cache and data/factory reset.
Update.zip from Bajo76

I flashed FJM6 (different from WJM6 afaik) last night, haven't tested it with GPS. I'll be sure to report back tonight when I do test it.
But quick question, is it really necessary to flash the "CSC" file?

CSC just has extra apps for different regions. I dont believe its necessary. But make sure you are using I9000XFJM6 and not I9000XWJM6. Then follow the guide and use the clear gps data trick before testing.

I flashed the XWJM6 version a few days ago, and was very impressed with the GPS... but the signal never locked below 20dbHz. I've seen screenshots from the I-9000 forum that show locks below 20dbHz with XFJM6 -- so I am very excited to flash this one, and I am planning on doing so now!
With Titanium Backup, should I worry about restoring "all system data" from my previous flash? Will it take over broken things that may have been fixed in the newer ROM?

The issue isn't how fast it locks onto satellites or even how many, the problem is KEEPING a strong enough lock (or any lock at all) while in motion. I'm running JH3 (With the "GPS fix" from the Evo, and it still sucks) currently and have run all the i9000 roms at some point and none of them are any better. So until I can see a video or a TON of people seeing no issues with keeping locks while in motion I'm assuming it's just like all the 20 other "Fixes" that have come out or implemented in the last month. Not trying to be rude or knock you, it's just getting a quick lock has been fixed for a while, it's maintaining a lock in motion that's the issue.

I understand completely. I look at gps fixes the same way after trying 10 with no luck. Once my wife gets home I will use her n1 to record a video of my captivate in action next to my evo.

That would be really cool, I thank you. I really really wanna believe it works like it's suppose to but like you said, there's so many fixes I've almost lost all hope lol.

I just tested the GPS with this ROM (XFJM6):
(1) I was able to lock onto 9 satellites (as many as my phone saw)
(2) It stayed locked on satellites <20dbHz
(3) I walked from my front steps, to my garage, and down the street... although GPS Test would say 16-32 feet accuracy, I swear it had me <10 feet accurate the whole time.
I'm not sure what is left to fix with the GPS... but this is the real deal (at least so far for me).
Next up will be full Google Navigation / My Tracks testing -- although I had very good results with XWJM6 already, I can only imagine it being better now.

Can we use SRE w/ this ROM or just the kernel?

I don't think you can.... when I was using jm5 for a while to do the battery mod I had to use the i9000 version I think.

I'm running JH3 right now - Do I have to flash back to stock JF6 ROM before applying this one?

I love you. (no homo)

shouldn't we look for discrepancies with this rom and a stock rom to see why this works better for gps than the stock one?
Not that I'm against flashing to this rom, I think it would be interesting to see why this has better gps fix than the stock

Can anyone test Bluetooth with these? Using the JM6 from the other thread my BT is 100% static on the receiving end.

Any idea on an ETA?

I flashed the rom, csc, and kernel - however I do not have a connection to ATT with my SIM card in - Did I miss something?

Try a different CSC.

What CSC is going to be in English? I did the German DBT one for S&G.. and can't seem to flash another one on top of it (BMC or OXA for example)

I downloaded the update.zip and did a "reset" - the phone is back in English - my connection shows an "H" where 3G would have been - am I supposed to have HSDPA? (just want to make sure I don't need to flash another CSC)...

For those still having GPS problems after DK05 radio flash

I still could not get a GPS lock even with the new radio and the DK05 ROM was still to buggy for me. So I went back to stock then back to 4.2 release of Froyo. I needed the GPS so I flashed the radio to the DK05 release and got 12 Sats in just a few seconds. This was the only combination hat has worked for me. Maybe it's just a fluke but it works for me even after reboot. Just thought I would share. I don't know why the rom version would matter 4.2 and DK05 radio gives me orking GPS.
Hope this helps someone......

Well known fix for a well known bug. Don't use GPS for a few days, then try it and report back, please.

I understand where your coming from but that's not what I was referring to. My point was that I could barely EVER get a GPS lock until now. I tried the "leaked GPS fix" in the other thread and if it worked it wouldn't after I rebooted the phone. I was simply reporting that with this combination of Radio and ROM that it worked very well. Before it would stop working when I rebooted but it locks right on now.
I am very aware the "Well known fix for a well known issue". This was different for me and I thought it might work for someone else still having issues.

I wasn't trying to be a **** or anything. What you did just forced a complete cache wipe and then a download of new data. Unless you use it daily and unless you have it set to cold start, I guarantee you that your issues will be back.

No problem. I guess my whole point was I had done the cache wipes many times with no positive outcome. This was really the first time I was able to use the GPS on my phone. Maybe it was just coincidence but I tried the cache wipe and anything else I could find to get the GPS to lock and this was the only thing that ever worked for me.

No GPS satellites in view
I wanted to share since I have the same problem...
I am now on my third epic as the first two would not even see a satellite for anything. Not sure if anyone else may be this unlucky but the first two were definitely defective. Third one works like a charm.
I do work for Sprint, and I've seen how shoddy quality control can be for some of the devices, but it seems like they almost rushed these out of the factory. Only had two customers come in that actually required a replacement, as the others were just the standard GPS issues, but man is it frustrating for this kind of phone.
I remember when I got my original touch that didn't even have gps enabled yet! How many years old and even with froyo on it, gps works near instantly for all tests.
But anyway, just wanted to share as I don't know that everyone who has been having issues has verified if they are even seeing satellites available.

Thanks. I was seeing 0/0 in GPS Status. No matter what I did I had nothing. I was swapped out a few times as well but for the capacitive buttons. I got it working pretty good now. Now I get 12/12 outside and like 7/7 inside. Stas seen/Sats locked

I'm unclear on which version is "froyo 4.2". Do you mean the DJ29 leak? NVM. I didn't put 2 + 2 together; you were referring to the 4.2 revision of leaked DJ29.
I'm basically in the same boat OP was, I'm flashed all the way up to the latest DK05 ROM and modem but GPS is still a crapshoot.
At least it's finally looking like the next OTA will for-sure fix the GPS problems. With Samsung supposedly never acknowledging the problem I was worried.

From reading the anecdotal reports of uncontrolled testing here, I've seen no evidence of that at all. Maybe it's fixed, and maybe it isn't. You should still be worrried.
People are overcoming the novel problem particular to installing the leaked version. This problem, apparently an artifact of the way the leaked firmware is installed, was breaking GPS completely at the outset.
But that is not the same thing as saying that Samsung has fixed the longstanding GPS bug on the Epic. In fact, having the GPS work initially is a symptom perfectly consistent with that bug. (You can get the same effect just by doing of factory reset of your stock Epic running Eclair DI18.)
The Epic's GPS bug occurs over time, as the GPS almanac and ephemeris cache becomes out of date or corrupt. As far as I can see, no one running the leaked firmware has tested the use cases that can replicate the bug on the stock Epic.

I'm not doubting that this is a bug, but my Epic has NEVER been able to get quick and accurate locks, and I have tried after countless wipes. Unless it's just bad hardware there is more then one bug in play here.
The OP's situation seems near-identical to mine so I'm hopeful that trying this might actually have results.

First the fact that samsung hasn't acknowledge the problem is not "supposed" it is a documented fact. They refuse 100% to acknowledge the problem and in fact say on the record all GPS issues on Epic were fixed at release.
Second there is zero evidence that the next OTA will do anything for GPS on Epic, where do you even get the slightest indication that is the case?

the OP situation is totally different an yours, it has to do with flashing, which killed the GPS on many Epics. IE not an issue with time to first fix, interrmtant falure to fix, or accuracy, but a total killing of GPS.
The fix implemented restores GPS to the same function state as the rest of ours, generally working with some number of failures to flush cache and thereby no fix locaiton on occassion

gps fixed with DI18 workaround

thank you guys so much for the gps workaround it works flawlessly now. my question is if i flash a new rom (currently running acsDK17) will my gps stop working again and also if i apply themes will that affect the gps or am i good to flash away?

I heard that if your GPS is working and you flash the DK17 modem your Epic will explode just like that poor kid's Droid X. Be careful!

I just want to know is after the gps is fixed can y9ou flash new roms and themes without breaking gps again

OK, I guess I'll give you a serious answer since no one else chimed in. The DI18 "fix" is not a fix, it simply resets the GPS cache such that GPS works and it looks "fixed". The truth is that if you have GPS issues, there really isn't a real fix yet. There are workarounds but the issue always crops back up (except for those lucky few who seem to somehow have fully functioning GPS, but they would have had it all along, they wouldn't suddenly have fully functioning GPS for more than a few days. That being said, I do now know of any reason why flashing a particular rom or theme would "break" your "fixed" GPS.

Which workaround are you talking about? There are several floating around aren't there?
I had problems on stock DI18, but after flashing Syndicate Rom, I have made sure to not have wifi or 4g on if I start GPS and so far I haven't had any more problems.

[R] Flashable jk6 GPS Files...?

Can anyone do this for me, im trying something out and want to see if it works or not...i would do it myself but got no idea :x help plz.

Why not just flash the rom? I can verify that the GPS in JK6 works great.

Yep, my thought as well.
People keep saying "oh, but I got a lock on 7 satellites in 30 seconds", but that doesn't help the fact that the accuracy is piss poor. Ran GPS Status & Toolbox and sat my phone next to my dad's MyTouch3G Slide. His held a solid reading to the 1/1000th of a degree, while the Vibrant jumped all over the place.

Bump... this would be nice.

Gps not working Whatsoever!!!

so i flashed the full DJ05 package through odin and it worked perfect... after it was done, i tried gps.. and it said initializing without stopping for at least 15 minutes and still no lock, so i flashed D101 through odin and it worked perfect and still no gps lock... what happened???

Had a similar issue after upgrading Maps to 5.0, un-installing maps and re-installing it fixed it for me, also make sure the location services are turned on.

From what I heard the dj05 update isnt really a fix for the gps,,,,, just a slight improvement.
The galaxy s phone are garbage in my opinion. Poorly made. Motorola makes the best Android phones hands down. And they support them!

From my experience the galaxy s phones have great hardware, they just have crappy software. The dj05 update helped my gps by a lot, I can get a lock in about 2 seconds. I have seen and used the droid x and the droid 2 and would still rather have the fascinate, huge improvement over my old eris even when it was running 2.2.

Then you heard wrong, unless by "slight improvement" you mean that GPS goes from non-functional/useless on DI01 to working fine in DJ05/DL09. The only time that GPS has issues for me is if I turn it on while moving, it takes maybe 20 sec. to get my location then, otherwise, it's better than my old phone by far.
Until you've actually tried it, how about not trolling here?

imnuts i had the fascinate returned it cause i hated it. my friend still has it with the update he says its a slight improvement in the gps area.
Either way the fascinate sux<<< btw thats trolling.

Ok new update on my gps.
I go to maps app... Directions... Type it in press enter... Shows me written directions... Click on the little blue arrow... Shows me driving and the blue arrow is moving in the right direction and what not bit it doesn't stop saying getting driving directions with the rotating blue thing on the left... So I wait and wait and wait............. And nothing!!! I even tried putting an address close to home and nothing!!!!......... Any idea what's going on?
This is also now my only issue with the phone. I tried rebooting and uninstalling and installing it back on.... But nada

Did you flash the DJ05 MODEM in additition to the rom? Just have to ask.

Well, to the know it all Bigboinkers above, DI01 was not downloading ephemeris data like it was supposed to, which is instrumental to GPS locks on phones.
DJ05 does, and so does DL09. They lock quite quickly.
So stop making BS up, kthx.

i will argue that your statement is incorrect, my GPS is perfect after i Flashed DJ05.
and it would not lock at all prior to flashing...

If you still have not found a solution, it very well may be a hardware problem. I would try everything again, and if that doesn't work, I would get a replacement.
And to the troll, go away. If you don't have a Fascinate, you don't belong here.
