CM7 GPS - no lto.dat?

Hi,
after spending some fruitless hours trying to get better GPS performance from my p990 (cm7 nightly 60-64, baseband 0218, cm7 RIL), trying various tweaks to gps_brcm_conf.xml and even older versions of glgps, I've concluded (tentatively) that
- /data/gps/lto.dat is a file (containing ephemerals?) that's used for A-GPS
- my setup never manages to download this file.
Following this thread of thought, I tried the following (The URL is from a google search while I was digging about in gps_brcm_conf):
Code:
adb shell
cd /data/gps
wget http://gllto.glpals.com/7day/latest/lto.dat
chmod 777 lto.dat
I also did
Code:
rm gldata.sto
to remove (I think) stored orbital data from previous fixes to try to keep the results comparable.
Though measuring GPS performance is difficult due to constantly changing constellations and atmospheric conditions, I think this has made a difference in time-to-fix for me. Admittedly this might just be a placebo, so no guarantees.
If anyone wants to try this and post their results, it'd be great. And, if anyone knows anything about lto.dat, why its needed, and why it never gets downloaded, please post here so I won't be kept awake at night wondering

It might be that the Tegra2 setup doesn't use it, much like gps.conf.
Best bet would be to ask RC I suppose, although he's a bit tied up with some GPL stuff apparently.

It's referred to in gps_brcm_conf.xml (the chip-specific config file), so I've assumed it's relevant to our setup. But yeah, it's possible.

Yeah, I'll hold off on that a bit.
Would be interesting to know if anyone actually has that file in /data/gps. I'll try to find time for a restore to stock (or at least modaco) to see if it gets downloaded in the standard setup. We'll see.

don´t have it on cm .64 either ...

Just created the missing file, and got a lock from stone cold, indoors pretty fast. Did that file help? Dunno lol
Will have to test more.

OK... here is my extremely unscientific test...
GPS Status without lto.dat: 43 seconds to lock.
GPS Status with lto.dat: 19 seconds to lock.
aGPS data was cleared before each test. Interesting, but far from conclusive.

Whooo! This is amazing!
Tried to lock inside without lto.dat, no luck at all after 70+ seconds... Copied the file into /data/gps, tested the same spot and got lock after cca 10 seconds!
This is amazing

Good find. That file basically holds an analog to XTRA data; It doesn't quite help picking up satellites, but it makes locking onto them a hell of a lot faster once they're found.

Indeed. That matches what I've observed.
Any idea why the download doesn't happen?

Download will happen for the next nightly, this is going to please a lot of people; top bombing.

This is truly awesome, hope it might have some small influence on apps keeping gps alive when screen is turned of too... Maybe a little too much to wish for, but..
Thanks send to nrkabul

It wont, that's just how Android works... my stock N1 was the same.
Endomondo excepted, that should be able to hold a lock, but doesn't. Run Keeper does it fine though.

I had stock rom, Gilgamesh and the first one WGLpoelstra posted, and Endomondo worked flawlesly on those roms, dont know what happened to GPS since then, but on CM7 i have to use My Tracks in the background to make sure that Endo records track.. Havent heard about keeper before, will check it out

another workarround: Install this https://market.android.com/details?id=net.canaryx.gpsaids&feature=search_result
and download lto file. open root explorer /data/gps and rename lto2.dat into lto.dat

It's a pain, and odd the Endomondo can't do it, when others can. If they all couldn't it would be an obvious problem, but when it's just that one (the one I happen to use at that) it's frustrating.
Still, as you've noticed, there is a work around, this might be less hassle than having My Tracks going though: https://market.android.com/details?id=com.kaukovuo.android.trackerbooster

lto.dat works great for me !!
got a fix in my car in about 5 sec, some seconds later got 10 satelites fixed !
GPS works like it did on MCR Rom for me now !
great discovery !

NeoFroyo!! Well testing

hey guys!
Well i was trawling the android forums and found this!
http://www.neopeek.com/viewtopic.php?t=7524
All thanks yo neopeek for the rom.
I decided to test it out on my kovsky. This coupled with I believe duckkly's kernels worked like a charm!! ill post the kernels up here too as I experimented with quite a few to see what worked best!
Battery life: 8 hours on full blast so i rekon around 11 on normal usage
Wifi: never ever ever dropped on me so far! thou it does seem to be weak in some places around my house where i usually should be getting more signals and strong at places where i get little signal :S.confusing
phone: well calls come in and stuff but sometimes ull see a black screen and cant see who's calling! :S
Bluetooth: paired with my mw600s just fine dont know about file transfer
market:works just fine a bit slow though..could be my internet speeds out here in pakistan.
Apart from that using whatsapp like a charm. facebook apps. gaaps everything works!! not a single sod to date been using it for around about 5 days or so.
Sorry for the spelling errors! big thanks goes out to neopeek and duckkly or whoever compiled those kernels !
PS: oh and the keys will freeze up as you hit around 20% battery. I simply reboot. Also terminal doesnt seem to be working. keeps crashing on me but i dont really ever use it in daily use so it seems to be pretty stable apart from these flaws. Also you'll need to reinstall quickpic from market
Also im on radio 1.16 i believe. 1.14 seemed to drop calls randomly.
please read all of neopeek's instructions before flashing ! happy flashing

can't confirm 20% battery being the point where keys stop working. for me 4 hours of uptime seems the be magic point...
i stopped restarting modules via script (how to has been explained many times in here) and simply restart. most of the time it happens when an app is running - now what good is it if you have a shortcut somewhere, but can't get there because back- and home-key isn't working?!
but yeah, neofroyo is a big step forwards. first time using android on x1 is fun!
for terminal to work you have to reinstall it just like quickpic.
i just hope we'll see some kernel-update soon. without it the whole thing is pointless.

lol truee..thanks for the terminal update. oh if u press the camera button it will take you back to your home screen. than i guess u could load the keyboard modules..annoying i never bother with it. try my combination of kernel it gives me decent battery lifee but yea its the kernel with all the problems. tried the new kernels but they dont seem to work properly

hm, which kernel-version is that?
might try if i know which it is. just had to step down from ygge-monster to ygge-turbo. monster made my touchscreen getting unprecise in left half.
thx for the update with cam-button - never bothered to press that, since camera doesn't work anyway.
yeah, new kernels suck for our device, especially since they're missing the specific battery-driver for x1. the only guy still working on x1-kernel has been silent for months, but i can see he's still at it (porting 2.6.35.7).

Just tried pressing cam-button.
Falls back to lockscreen, after unlock shows homescreen. But system is frozen and after some time reboots directly to android. But lots of stuff doesn't work, especially phone-stuff. So i have to reboot winmo anyway.

i think its the ducckly's keyboard not loaded as modules turbo verison. I believe it should be that because i remember the msm drivers werent really working properly on it

Rooting my phone has turned into a nightmare, can you help me?

Ok firstly I'd like to say I just rooted my phone last week, this was my first time doing it. I decided to do it to get rid of various problems (I was led to believe rooting fixes everything). Some of them went away, some of them stayed, and new ones came up with the rooting.
I was coming a stock LG Optimus 2X P990 with Android 2.3.4 (had been updated because the phone was originally older 2.2.2 I think.. I'm not sure), and rooted to Nova HD Rom (ICS 4.0.4) using this thread : http://forum.xda-developers.com/show....php?t=1508492. Oh also, I'm using SPB Shell launcher.
Problem #1 : Signal interuption. This one is probably the worst problem I have. I rely on my phone a lot as I don't have a ground line I need it to catch all my calls. About 2-3times a day I'll check my phone and I'll have no network. Sometimes the signal bars are frozen, they don't flutuate as I move to different areas. Sometimes there's an X on the signal logo. Either way, where I go inside/outside.. my phone can't get network. At first I tried to activate/de-activate 2G, turning on/off airplane mode to somehow reset the damn thing, but it just won't pickup. Then I tried a reboot, after the reboot.. still stuck at no signal. Then I finnally found how to fix it.. a full power OFF, and back ON. That's right each time I peak at my phone and it seems to be doing this, I need to make a complete shut down to wake his ass off.
Problem #2 : Battery drain. Well after days of reading on the subject apparently rooting my G2X was gonna improve it's battery life. Result is : no difference. I've bought a bunch of apps to try and keep track on what's wrong (BetterBatteryStats, Battery Monitor Pro). Just this morning I unplug my fully charged phone at 7:00:AM, and by 1PM (6hours later) it was done. There was about 1½hours of awake time, and about 50mins of screen on (perhaps half of this was using my 3G internet with various apps), no SMS or Calls. Usually if the phone is kept sleeping it can last about 24hours, do you guys think this is normal battery drain?
Problem #3 : Phone Clock off? Last week I was woken up by my alarm in the morning to find out I was about 40minutes late. Only happened once so far. I checked to see if I had set my alarm incorrectly.. nope, then I saw my phone time.. It was was OFF by 40mins... WTF? I went in the options and everything was fine... "Automatic date & Time" checked. I unchecked/checked it, and it didn't fix it, I had to reboot the phone for the time to come back to normal. Now hopefully that was only a one time problem, only now I have to live with the stress every morning my phones time might be wrong and I'll be late for work.
Problem #4 : Seriously where the hell is my FM radio. I use to listen a lot of FM radio before I rooted my phone , this is a feature I enjoyed. After rooting the FM radio application was gone, I said what the hell I'll just get another app from google play. NOPE, not a single FM radio app (that works). I tried a bunch of stuff, read on the forums and searched google for like 3hours and couldn't believe how much work I had put into such a simple thing.. this is so infuriating. The next day I kept looking but was never able to get anything working.. Oh and every where I look people say "lol why use FM radio when you can stream 1gazillion radio with given apps or whatnot". DAMMMMMMNN CAUSE MAYBE I DON'T HAVE INFINITE DATA PLAN? (In fact I have only 500megs/month). Seriously I'm so mad about this.
Problem #5 : Can't copy MKV files?! . I swear to got now that I rooted my phone each time I try to do something, something ****S UP. I just wanted to plug in my phone and copy some episodes of a serie I watch. Each time I tried copying the files : BAM "Windows Explorer has stopped working". So after another 2hours or so of trials and errors I figured the damn thing out . If I try to copy anything, it works. If I try to copy a *.MKV file, explorer crash. A solution I found is renaming my files to *.****YOU and then copy it and rename it back to MKV after it's done copying. Then I wondered, what if I rename a txt file to mkv, will it crash when being copied? Nope won't crash. So it's not just the extension? But why does it work if I remove the mkv extension.. oh good god how the hell am I supposed to understand anything.
Problem #6 : Can't play that MKV file?. Hey I finnally copied my file, the next day at work during my break I open my phone to watch it and.... well I realised there wasn't any video player included in my ROM, so luckly this time I found apps on the market that could play it. I used MX Player. Oh alright time to watch it? NOPE The video is all laggy and skipping frames like hell. Also audio is off and about each 10sec it mutes as if it was re-syncing the sound. Later the next evening I wasted another couple hours figuring this one out. What comes out often : they say use Dice Player instend! LOL Funny! The damn app won't even open my file!.
Playing with my phone I opened an APP I've pushased : System tuner pro. Looking at the CPU stats I noticed the first CPU was at 1.01Ghz, and the second one was at 216mhz? What the hell? I thought isn't that suposed to be 2x1ghz dual core?. So I cranked up the thing up to 1.01Ghz just like the other CPU, opened MX Player and already my video was almost watchable (a definitive improvement). I went back in System tuner pro, and overclocked the damn thing (even tough I had no idea if it was safe to do so) to 1.4ghz on both cores. Another significant improvement, this time when set this way I could watch my video! And the app onlyl reports a 5Celcius increase so I guess it's fine.
My only problem/question about that is why does each time I reboot my phone does the damn thing turns back to 216mhz? In fact why was it set to 216mhz in the first place? Considering all the problems I have and that I reboot my phone about 10times a day, I can't just go in system tuner the re-set my CPU settings each time?
Hopefully you guys can help me.. I'm exhausted I''ve been searching this forum and the web for the last couple days, I have like 1000tabs open in chrome. Btw this forum is a goldmine for information but damn it's a lot of reading.
Thanks in advance for your help

First, I'd like to say that I admire your keenness to detail in writing all of your issues down. Thing is, most of the problems you have are mainly because you flashed a modified ICS ROM. ICS roms by themselves are in beta stage, meaning there are some things that people compromise in flashing them (such as the missing FM radio), and you flashed a modified one, which might be the reason for certain power saving features such as your 2nd core down stepping to 216MHz.
Thing is, most of those were discussed in the NOVA ICS thread.
I would recommend flashing the more stable ROMs. Temasek's CM7, DjangoManouche by Carburano, Nostalgia by Topogigi (Froyo ROM) are the ones that pop-up in mind.
For a panic button, you can do a smartflash and it will restore all partitions to stock LG (wiping all user data of course).
Anyway, read the threads carefully. The opening posts and the last 5 pages at least. In order to get a feel of user experiences with the ROM.
Goodluck and happy flashing!

I also noticed that you mentioned you have a G2X? But you also mention having a P990. If you're on a G2X, you have a different forum section my friend. This forum section is specifically for the O2X.
Flashing an O2X ROM on a G2X may result in softbricks.
(Please disregard my advise about ROM choices if you're have an LG P999 G2X, those are all intended for the LG P990 O2X.)

yea my mistake when I typed G2x.. I meant O2X.
Thanks for the advice.
If I change my ROM will it wype all my user data again? (sorry im a newb at this)

The ROM itself might not. But I highly recommend you wipe your device since you're moving from 1 version of android (ICS) to another (Froyo or GB).

I'd recommend you CM7 (not CM9) based ROMs but since you need the FM radio, they have none AFAIK.. but you can try stock based ROMs that are still in active developments by the dev. Usually they worked just fine and will fix most of your problems.. again, don't use CM9 based..
Now for the network that is constantly disconnecting in background, this bug is actually introduced (at least for me) after the GB update (i assumed because of the changes LG has made to the baseband). There's no surefire fix for this problem.. try different combinations of basebands and RILs.. stick to whatever works for you
For battery, if you're in constant mobile network, 24 hours standby time is incredible IMO.. our battery is just too low in capacity to make it last any longer than that.. my only advice is minimize the number of apps in your device, because some of them always stay in RAM doing god knows what..
Good luck

Yes it will wipe them.. for baseband changes too.. so if you have apps that you'd like to preserve, back them up before flashing anything.. Titanium backup will do the trick, but some instability issues might appear if you choose to just backup and then restore everything up.. so choose all your important apps and leave the rest.. this way if something is wrong with the rom after restore, you can at least pinpoint which app is causing it

Which both are solved to about 95% by using etana kernel.
In short CM7 is the most feature complete ROM without sacrificing performance on our phones.

Just to give an update I have changed my ROM to a CM7 based rom like u guys said. Temasek's kang build
Problem 1. Signal interuption : problem is definitly solved.
Problem 2. Battery drain : definite improvement, battery now last at least twice longer
Problem #3 : Phone Clock off? : Didn't get the problem again, so solved.
Problem #4 : Seriously where the hell is my FM radio. : Well I got an FM radio app, but I can't make it work. It doesn't pick up the stations..
Problem #5 : Can't copy MKV files?! : Well this is solved yes and no. If I manage to make my computer detect the damn phone, I can copy whatever I want to. Thing is for some reason I can't seem to be able to plug my phone into Mass Storage mode anymore. It worked a couple of times and all of sudden even tough I didn't change any drivers, my computer just doesn't see the phone anymore. I get a "USB Composite Device" with a yellow "!" mark in my device manager.
I tried a bunch of stuff in the options, rebooting the phone and/or computer, nothing worked. I decided to try reinstalling the rom, and boom right after I pluged it in, the USB Mass storage mode worked. Once again after a couple of times it started doing the same thing (yellow "!" mark in my device manager), and no new drive being detected. This time I'm completly clueless on what's going on, and I have no idea what I can do about it.
I'm currently copying files using Samba Filesharing over Wi-Fi, but sometimes I'd prefer using my USB cable, and I just can't...
New problem!!! : I had my phone at work yesterday and pluged in my headphones to listen to music, start my music and the sound was playing in both my heatphone and phone speakers. I tried unplugging/replugging the headphone, now the sound only worked on the phone speaker. Looked up every phone option possible regarding sound or headphones.. couldn't find nothing. I did a reboot on the device, and bam fixed everything. Couple hours later I re-open my phone for music, same problem occured. Had to reboot the device for the sound to be back in the headphones.
Most problems are fixed, I Guess I'm satisfied, but damn can't everything just work...

JuiceDefender Premium will make it that your device loses 1% every 10 hours if screen is off.

Stock 20Q from LG is free of bugs and full of functions.

Might be a stupid advice,
but you do know that you need your headphones plugged in for FM radio? (they are the actual antenna)
In the settings you can also set your region (e.g. North America or Europe), since the frequencies differ a bit (e.g. Europe uses 0.1MHz 'jumps' and some regions 0.2MHz).

yea I know all of that don't worry.
The FM radio app is pretty buggy, today I made it worked. Once the app was started with the station selected, I hit the home button then I pulled down the tray and click on the FM app from there. All of sudden I started hearing sound.. it had worked.
Turns out the app is also the source of what is messing my headphones up. When I close and re-open the app, the sound will come out from the phone speaker, and that messes up every sound from the phone then on.

That FM radio thing is a bug that I haven't heard of actually. When you have the opportunity (or maybe on the next build #94, I'd suggest a full wipe then reflash).

[Q] Any way to enable NFC while phone is in standby?

Hi is it somehow possible to port those modded Nfc.apks to our stock 4x HD phones?
I tried some of the modded Nfc.apk, but none of them seem to work
NFC is pretty useless when you can't use it while screen is off.
Can anyone help to get nfc working while screen is off?

tbh i would prefer NFC not detecting when the screen is off. imagine it going off accidentally in your pocket if so ever happens that your credit card or some other NFC 'device' activates it. the small trouble of unlocking the screen and tapping is worth the other troubles to me.
Not able to use it while screen off - we're not using the phone - is a good way to prevent negligence discharge =D army term =X

NFC is pretty useless without the option to have it always on. Google had this integrated, but changed some time ago. Most users try to get back to this state (AOSP, Cyanogen, etc.) or to let the user decide what he wants (off, activated when unlocked, activated when display on (and locked), activated when display off).
Why always on: It would be very nice to activate/deactivate things when you put your phone on your table etc without the need to unlock the phone first (then you can also push a button, so no need for nfc).
Although we have no useful NFC applications here (no payment for example), I don't think that always on is a security problem. You need to get really close to transfer something, so this shouldn't be a real security problem.

hi I have the same issue. NFC makes no sense when you have to unlock the screen first.
I have found this for the HTC One X.

This issue really irritates me, so yesterday afternoon I decided to run head on at a big learning curve and have a shot at decompiling/editing/recompiling the nfc apk myself.. I flashed my edited apk, turned of the screen scanned a tag and it worked! ..Assuming it worked I left it alone..
This morning I realised that my edit only work for 15 seconds after turning on the screen :/ LG have added their own edits on top of the android source, and honestly Im not even sure what for.. Something in that code is contradicting with the android code and I can't really afford to waste more time on it atm!!
I'm attaching my half working APK file if anyone fancies playing with it.. The key value to play with is POLLING_MODE: a value of 0x1 means NFC should work with the screen off and locked; a value of 0x2 means the screen must be on but can be locked; and 0x3 means NFC will only work with the screen on and unlocked. I also made some minor edits elsewhere.
Anyways, sorry about the long post! Just trying to give people hope, as this is most definitely do-able, and probably not too difficult either.. But not by me as I really can't be doing with getting my head around smali when I am supposed to be doing other things
Note:-
Attached file is intended for firmware v10f, just push the file to /system/app/Nfc.apk using abd.
If you can work out what changes about 15 seconds after the screen is turned off, I would love to hear it.
MAKE SURE YOU BACKUP YOUR ORIGINAL Nfc.apk BEFORE PUSHING THIS

You have to rename nfc.odex (nfc.odex.org or what you want), if you don't do this the code will be replaced with the one in the odex file after reboot.
There also an other thing with the deep sleep mode which starts after a few seconds (15-30s) . In deep sleep mode nfc is not working until the phone is waked up.
But except that your modification ist quite useful. Nfc is starting immediately after the screen is turned on and this is much better than the default behavior.

So. Which ROMs are you using??? Isn't anybody using a signature here?
If I get a fast answer I would try to make it with my usual method but you have to test then.

At the time of the last post on this thread we had no custom ROMs as there was no way to unlock the bootloader.

We have an unlockable bootloader. We have various ROMs based around Cyanogen 10.1 but with a couple of AOSP variants appearing over the last few days as well.

With the slim bean ROM it work.

gps issue

I might have broken my gps while I was tweaking my XZ (.569-firmware).
can anyone upload the FUSED LOCATION apk ? I need to know if thats the reason why my gps won't work
Details:
1. It won't find satallites but gps shows as active.
2. the quicksettings gps-symbol is stuck (and won't change its symbol and won't turn on/off gps when pressing it).
I'm searching for the culprit...
Maybe one reason:
Like I always do after flashing a new rom
I deinstalled FUSED LOCATION and NETWORK LOCATION...that wasn't an issue with all androids including 4.2.2. Maybe with android 4.3 these apps are necessary for gps to work?!
Of course I made a backup of these apps with titanium backup, but I can't restore FUSED LOCATION (Titanium Backup gets in a loop)...

Why don't you extract it from the FTF yourself?

...just imagine this story:
I'm on a super secret mission in the jungle,
1. have a slow internet connection, can only connect to xda and a download-page (thanks to a super villian who told me his whole masterplan when we met and then gave me this phone),
2. I have no PC with me...
3. I have only 33% battery left...
I only need to know for a brief moment where I am (by GPS). that would be suffient to survive.
loading a ftf with that connection would take 2 weeks, unzipping a approx. 700MB-ftf-file with my XZ would take an hour (and deplete battery)... then there is the question if there is an android app for extracting apk from the .sin file and how long that would take...
My only hope: You and the fused location.apk (which even sounds like a super weapon)
Downloading that would take me 1 hour, but I would survive, could kill the villian, then save the world (and a super hot chick)...and you would get a medal!
Or do you want to be responsible by not helping a person in need?
Edit:
Of course the villian also cut off all other communication features of the XZ before he handed it to me

My gps works! thanks alnikki
Now I'm going to fight with every single unimportant enemy (of course: one-by-one, as they can't attack me as a group) until I get to the super villians headquarter in the middle of the jungle... As you might have already guessed: my mission involves satallites... I can't tell you more, but rest assured: Today you helped mankind!
