What affects the GPS? - HTC Inspire 4G

I've been using CM7 on my phone for about a month and i really liked it but the GPS didn't seem to work very good.
Today I wiped my phone and installed CoreDroid 6.3 but the home and search button are not working (My phone is still using the CM7 Kernel so could that be the problem?) so I'll either try and fix it or flash a new rom (most likely LeeDroid). I am tempted to just flash the stock rom back on it and reroot the phone because I love the HTC Camera.
What would affect the GPS on the phone? Is it the ROM that would affect how well the GPS works or the radio?

There are quite a few things, the basics being Radio, RIL(Radio Interface Layer), and the settings on the phone, such as the NTP connection. I have found that using the updated AT&T RIL and Radio with CM7 gives me like stock GPS. Full and quick locks. Like under 10 seconds (after the initial 45 second lock). At least, that is my experience.

Can you post a link to the updated AT&T RIL and Radio? There are a ton of radios and I'm not sure which one is the right one.
I restored CM7 so it's on my phone again.

Try Angel Death's GPS files for whatever region of the states you live in (Northwest, Southwest, etc) I have CM7, and without it, the gps is so-so. With it, I can get a lock of 2m within 10-15 seconds, without use wireless networks enabled.

I installed the file for my region so hopefully that helps out.
I'd still appreciate the links to the updated AT&T RIL and radio so I can flash a new radio to my phone.

Here's the link to the radio. Use the one in the second post.

CyanogenMod 7 Radio

I am having trouble finding a radio that works with this ROM.
The main problem I am having with the radios that I have tried is:
Weak WiFi signal and GPS not connecting fast enough or not connecting at all.
So could someone please recommend to me a radio that they have working well with this ROM.
Thanks.

What radio are you running currently?
What RIL are you using?
Have you tried "double-flashing" the radio/ril?
Have you rebooted at least twice after radio-related changes?

I've been having this same problem aswell, I have yet to figure it out, and I don't think anyone here knows the solution. I start to wonder if HTC has more than one wifi antenna going around. Or maybe something is just wrong with ours.
The only thing though is, it only does this with AOSP roms, sense roms are just fine. I say give one a shot.

Me neither. Seems like someone's always having some sort of problem. I have the feeling the common denominator may be your last sentence.... Clean install.
I think a lot of people are looking for some magical power to give them super ultra lightning fast data speeds and 1/2 second gps lock times with 1/2 meter accuracy. Or something.

[Q] Wrong accidental GPS driver flash

Hi, I flashed this GPS driver late last night to my HTC Inspire (prime time for mistakes) and now I realize it's for another phone (DO'H!). Will this affect my GPS in a negative way? What can I do to get back? The file I got is from the thread below. Thanks!

RIL: HTC-RIL 2.2.0018G
ROM: CyanogenMod 7.1 R1

I actually did something similar with the InspireMod for CM7. I flashed a GPS fix for the wrong region and didn't have it working for a while, but a simple flash to the right region fixed it. If you can find the right drivers I don't see why you couldn't just re-flash them, hopefully it will be all good after that.

Maybe you'll get lucky and won't experience any problems, but, not having an in-depth knowledge of how these things operate, what files are affected, etc., if I were in your situation, I'd just reflash the rom, just to be on the safe side.
Unless you want to go to the trouble of opening up the zip you flashed, seeing what files are in there, and then, if they are in fact files that would have overwritten what you already had, tracking down those files again and replacing them... Easier to just reflash and be done with it.
If for no other reason, every time you get sub-par gps performance, you'll always be questioning whether this accidental flash has something to do with it.

Good point. I'm going to reflash the ROM if the GPS gets overwhelmingly buggy, but for now its just a little buggy. I can't really tell if the GPS was worse or not because it was pretty bad before I flashed it and now it seems to be semi-okay with this GPS fix (haven't really used it that much yet so I'm unsure).
Yeah definitely something is up. I get such a good lock, but when I start moving in the car it loses the lock. Super bummed. I'm going to reflash 7.1 again either tonight or tomorrow.

I think that's the wise thing to do. Once you've eliminated this unnecessary variable, you can focus on addressing any gps issues you have starting from a clean slate.

Getting tmous GPS to work with Roms

Hello I would like to take a quick consensus about people on tmobile us and if their gps is working. There are a few fixes around the dev forum but they do not work for me. A lot of people have been taking gps.config files from other roms or RUU and dropping them into the phone's system/etc and /etc folders overwriting the current one. I've tried this and it did not work for me, has anyone successfully fixed their own gps and got it to lock? Thanks.
I've tried about 5 roms and my gps locks instantly every time. I have a t-mobile sensation.
GPS has worked flawlessly for me on LeeDroid.
gps works flawlessly and locks instantly for me
used both leedroid and insertcoin(which im using right now)
No problems here. Fastest GPS lock of any android I've had to date.
I'm using a T-Mobile Sensation, debranded and running EU 1.35
haha oh man maybe this is a personal problem then, are you guys using stock kernels?
Yeah I'm on the stock kernel.
Leedroid kernel 1.4 beta, damo's gps fix, and first lock took around a minute. Now it's almost instant.

I have almost no gps whatsoever...I'm in the same boat as you as I posted in the Q & A section.
Running Android Rev 1.1.5
I use to be able to get GPS lock in my room. But lately I'm unable to get a signal at all. When outdoors, Google Nav just keeps saying "Searching GPS...". I'm not sure what I did wrong but something isn't right. Also I already tried the gps.conf and gps fix apps and it didn't seem to matter.

After flashing the patch from 1.1 to 1.2 and also the 1.4 beta kernel I find that my GPS is very erratic --at times it will not lock at all and then it will lock within 20 seconds and then about 10 minutes later it will not lock--and just a few moments ago it would lock and then lose it and then in a minute or so it would lock again and then lose it and now it is not locking at all. I have used FasterFix and it would seemed to help and then after flashing patch and new kernel it does nothing. Could someone point me to the damo's fix? I would greatly appreciate it.
My GPS positioning is pretty sad on stock, and you made me reluctant to even try other roms now.
My gps works great in InsertCoin 1.06
Same here....gps is slow sometimes. I edited my buildprop. I blame mysrlf

Are you able to upload the files you used? and is suplrootcert in system/etc/ also? I;m not by my phone to check right now. Thanks
Here you go. The first one is stock, the second one has additional NTP servers added. (north-america 0-3, us 0-3). push this file into /system/etc.
Once you're done, test it out by actually being outside. Remember, GPS rarely works inside parking structures or houses
Do not flash this in recovery. Push this onto your phone using adb. I'm assuming you're gonna know how to do that.
"adb push gps.conf /system/etc" is the command you'll be using. if it's telling you that you don't have permissions, do adb remount and try again. be sure to push the suplrootcert as well.
I downloaded astro and know how to use it..do i just copy and paste the zip in the file or do i flash it? and if i flash it do i do it from the recovery?

[Q] July Baseband/ Custom Rom/ Instant GPS

Hello All
I Recently updated my baseband after much frustration with GPS and pleased to say i now have GPS instant locks. real instant locks 1-2 Second. Now, I am really wanting to flash a custom rom w/out losing my current GPS state. Can anyone confirm that has done the same thing (updated baseband and achieved instant locks) That after you flashed a custom rom you still have instant GPS locks? and which Custom rom you flashed? Thank you in advance EVERYONE.
You can flash a stock 2.3.3 based ROM, and GPS will work perfectly.

I'm running Gigglebread, which can be found on RootzWiki.
I've never experienced an issue with it, and GPS locks are pretty good. I average 14-16 hours of battery life @ 1.2GHz OC with -100 mV underclock with Faux123 CM Kernel.
For a stock based ROM, I would recommend Tsugi's 2.3.4 ROM.
Thanks for your reply. I ran tsugi previous to updating my baseband and yes tsugi was great. Does it not matter that it is stock 2.3.4? And not 2.3.3 based. Gps wise?

I'm so glad I found this, cuz I'm xtremely satisfied with weapon 3.0 and dont wanna go back to stock,,,,
So just to recap a bit, you went back to stock, updated baseband, reflashed weapon and all is good? when you reflashed did your wipe cache & dalvik and format sys?
And also, are you having any problems with usb not mounting extrl sd to computer?

Yes. I was running tsugi, then updated baseband, reflashed CWM using NV flash, Rooted using JBoxer posted root.zip, then reflashed weapon, before flashing I followed whitehawks directions in OP: I wiped/ data factory, wiped system. Then flashed the rom, Everything runs perfect as it did before only now I get instant gps locks, data, wifi, mounting ext and int sd works perfect as it always did. Hope that helps
Now an even more stupid question. I have service through Cincinnati Bell... if I want to update my baseband, do I need to find a special file? Or will the July basebanf thread work? Is that baseband file specific to T-Mobile ?
If I need a specific baseband for Cincinnati Bell, would anybody know where.to go for that information? It seems that the.Cincinnati Bell G2x users are an ultra small group .. so threads are limited.

I updated my baseband and now every ROM I've run has almost instant GPS locks. Granted, stock and 2.3.3 based roms like weapon and Tsugi or even Baka get quicker fixes, but to me, you can't give up the added functionality of CM roms like eagles or Phoenix blood. Flashing any other rom shouldn't alter your baseband at all. The new baseband in conjunction with apps like GPS fix and faster fix should add up to almost instant locks on any ROM.

Thanks. Ive actually ran those mentioned roms and gps fixes (when I was on old baseband) for me personally they had too many bugs in the features I used most. Great roms nonetheless, just lacked in areas I needed. Weapon s works perfect for me. I understand roms do not change baseband, I was just curious as to if it affected the gps functionalityThanks again for your suggestion s
Well I suppose that is why we have a recovery Nvflash.. I'm gonna give it a shot and see what happens.
I'll let you know and then we'll have the answer to whether basebands are carrier specific.
I would sure love to have GPS locks... on average it takes me over 10 minutes to get a lock. GPS status shows that I see and am using 5 or 6 satellites .. but when I open maps... it just takes forever to get a lock.

Stock and CM7 based roms mount the internal and SD card differently. You will experience problems if you install applications to your SD card on one type of rom and move to another. Changing the mount point manually (editing vold.fstab) will fix some of the problems (ie. your programs will launch properly) but will disable USB mass storage as the rom will try to mount the wrong (virtual/)directory to the USB path.
This is just from my own experience going between EaglesBlood(CM7) and Weapon(Stock). I'm not an expert at this but I tried five or six different changed to the vold.fstab and couldn't get everything just right after switching from EB to WG2x.
Anyways, I wouldn't be surprised if there is a way to make the current structure of your internal/external storage work with a new structure, and have USB mass storage functionality. I just haven't found it.

Very brave! I would have done it in your position too. Instant Gps locks was a must for me. Looking forward to the update. I'll be praying for a good turn out
Flashed following instructions ... it appears the basebannd was not cell provider specific. Or, if it is, entering the apn information straightened it out. I have the July 15th baseband and my phone still works.
However, it makes no difference in my GPS locks. They are still slow. Maybe I will edit the GPS configuration file as mentioned in a couple other threads.. and see if that coupled with the new baseband will improve it.
If you care at all, I will post an update.

Absolutely I'm always open to learning. Thanks for your update. Have you tried gps running stock? Immediately after updating baseband, our did your just reflash weapon immediately to test run gps?
Did.not test run ... immediately reflashed...
However, in the GPSconfig file I disabled the wifi wiper (very bottom of file, change value from 1 to 0) and I had instant GPS locks.!!!
I mean instant.... less than 5 seconds. May be a fluke so I'm gonna drive around and periodically open maps to see how long it takes to lock in.

Canadian Skyrocket GPS issue (i727r)

The GPS takes 5 minutes to lock, and it does it at 1600 meters (un)accuracy.
It behaves like this no matter what rom i try (Sky, Slim, CM9/10, Embryo etc), except for stock Rogers ICS.
The agps patch and other gps patches on XDA didn't do anything.
When i first bought it, it had stock Rogers ICS and GPS worked perfectly, never mind the fact that i live in EU.
Then i tried custom roms and it started to funk around and has been doing as long as i run a custom rom.
Today i installed Rogers ICS as a last resort and suddenly the GPS locks in seconds and with great accuracy too (9 meters).
And so the question, what the hell is causing this?
OR
How do i make the GPS work with the custom roms?
I have been running custom ROM's since a day after I got my Skyrocket, and the AGPS patch has never failed to work for me. I have been running CM10 for pretty much the last 4+ months, and GPS always works. Not sure what your issue might be.
You can flash agps patch from Boombah's aroma installer. Always works for me

I'm not sure either.. The phone is canadian with a Rogers brand on battery cover. When i install a stock AT&T rom the GPS more or less dies.
Any other rom and the GPS dies. Stock Rogers ICS rom and voila works like a clockwork.
And it doesn't react at all to any GPS patch, and i've tried like 10 different ones. aGPS is not new to me, i've successfully used it on other phones. But for some reason it doesn't do anything for my Skyrocket.

Thanks i'll try that, just don't see how Aroma is going to help if it's the same patch i've tried earlier.
On the other hand, with ghouly issues like this who knows what might help and what won't ?
Worst case scenario is that i'll be stuck with Rogers FW if i want working GPS, which is acceptable with some tweaks especially the Droid Razr M launcher

Nope, it's always turned on.
If SW doesn't solve/change anything - where might the problem be? Yes, that's right, it's probably in HW!
Check your GPS antenna contacts (antenna is inside the inner plastic, the one you see when you open back cover and remove the battery). Bend them a bit and clean their contact points to make sure they contact well.
If your phone is still within warranty or the above doesn't help - replace it.

Hi Jack_R1
Software does indeed solve everything. In short: stock rogers ics rom = perfect gps, custom rom/stock at&t rom= no gps.
Oops. Guess I skipped some lines reading the OP - returned and found your line talking about it. Sorry about that.
Did you try reinstalling custom ROMs after you got quick lock on stock ROM, to test that the issue remains?
I'd suggest a couple of things:
1. Try installing AT&T ICS ROM for testing. If it also gives you a good lock - you'll have better reference point.
2. Look at the APN you use in Rogers' ROM and in other ROMs. If you're using automatic ones - they might be different and include GPS-related stuff (type "supl").
3. Copy stock gps.conf from Rojers and try using it on custom ROMs.
4. Download FasterFix and try choosing different NTP pools.
5. Download GPS Status & Toolbox, see what exactly happens when you run it, describe here. What satellites are you seeing (numbers), how much time after running it, in which condition, etc.

1 The AT&T roms didn't give me an adequate lock, until the JB updates were leaked & released.
2 I'm always using automatic APN's but they don't have any GPS info.
Haven't tried #3..
4 FasterFix didn't help.
5 GPS Status shows 4-7 satellites and only 2-3 locks with horrible accuracy. The thing is now i get perfect locks with any ROMs.. I could've disallowed Google Services to use GPS as I might've confused it with Google Search & Ads wanting my location..
Thanks for your help :good:
