[Q] GPS Broken

Hi,
Few month ago, my N1 falled on the street and the touch screen broked. I ordered a new one, dissassembled the phone to replace it, reassembled and everything was working fine.
Then one week ago, i dissasembled it again to clean some (a lot of) dust that went under the screen. Now everything is still working except the GPS.
GPS test doesn't show me any satellite, nothing... it just say "GPS on"
I'm using cyanogen 6.0 rc3.
Does anyone knows where to look inside the phone to check if something is broken ?

Have you tried a couple of different ROM / kernel combinations to make sure it's not a software issue?

Well i was using kang o rama 1.0 b2 with an intersecraven kernel, then i switched to the last service pack of kang o rama (so based on cyano 6.0 rc3) with the kernel that comes with it.
I think if there was a problem with gps in the the cyano / kang o rama, it will be widely reported here. And the GPS was the only thing that always worked fine in almost all roms /kernel i have tried.

Many users report problems with GPS on RC3. Check that thread.

The GPS problem occured days before upgrading to RC3. I installed RC3 only to see if it fixes something but nope.
People on the thread says that with the RC3, it's quite long to get GPS lock, about 5 min. For me, it's impossible to get any GPS lock, even after half an hour, outside during a sunny day.
The problem started to show right after dissambling the phone, not after changing software. So i suppose i did something wrong while reassembling.

if you made a nandroid you can try flashing it back... as gerikss said, many users are having gps issues on CMRC3

heya,
I was having GPS problems as well with my first Nexus One - turned out to be hardware problems, had to send it back.
I installed GPS Status from the Market, and mine wasn't able to see any satellites - is yours able to see any satellites?

Hmm, it sounds like you've put yours through the wringer though...haha...and taking it apart? Yeah, not sure if warranty will repair that for you. You can give it a shot?
Cheers,
Victor

The problem is not in the phone but the RC3 build which is widely used right now. Change it and I GUARANTEE it will work fine. FYI.. Rodriguez, Cyanogen, and Kang all use the build.

Is my english that bad ? My GPS problem started to occur with RC2 ! then i installed RC3. And they started right after dissambling my phone, not after any kernel / rom / radio / software change.
Like victorhooi said, GPS test program (or any gps diagnostic) is giving me no signal.
No matter i dissambled it or not, my phone is not under warranty, I got it offered at a google conférence.
I guess i'll have to live with only 3G location until a new phone will make me want to leave my N1.

most likely if the gps is showing "on" as you stated in post 1 then the gps isn't "broken", but most likely a loose connection. Some problems are solved flashing back to factory rom. If the gps was broken it wouldn't activate.

this post fixed it for me.

Hi,
flashed modaco r21 with stock froyo kernel, did what's told in the previous post (in fast, it was already like this). Still no GPS. GPS Test shows me no satellite.
I tell you, it's inside the phone. Maybe something is really broken, maybe just not connecte something correctly. But i want to know where to look before opening it again.

I'm having problems with my GPS too. I remember that it used to work well with FRF91. I still have locked bootloader and I rooted yet. Most of the time, it takes me a while to get a GPS lock, 5-10 minutes. Sometimes, it never gets a lock. Any ideas?
Update: I fixed my problem with the link in post#11.

[Q] wifi error after new kernel

I have a v20l and i flashed the hp kernel but now wifi gives an error
I flashed the hp for v20l from spica1234's thread
Can this problem be solved?
thanks

Reboot after attempting to turn on wifi it should work flawless then. I had this from time to time also with other kernels.

I tried that but didnt work, any other suggestions?

what kernel do you use? RC9 or SR2? in my exprience SR2 gave me wifi error ater 1 day hours of usage. and juice defender is also make it problems with HP kernel
right now i'm using RC9 and already 1 day 6 hours and still no error on wifi yet will let you know the progress. and i set the wilress sleep policy when screen turns off

I was using rc 9,
But now the problem is solved, first i flashed performance pack 7 and then rc 9 again and it helped.
But still dont no what was causing the problem

ow, so you have already flashed the RC9 kernel. maybe because the wifi module still use v10e on sr2, in RC9 used v20L sources
but in rc9 tun.ko can't smooth working like in sr2

Hi
I see a lot of people complaining about wifi problems
Even thought it was a faulty device, but it does not look that way
How to really fix the issue ?
Its not a cheap / low end device to just keep rebooting everytime as a workaround
For ex, i put the phone in airplane mode, just to check, then turn off airplane
and wifi dies...
Or if i disable wifi, and try to enable again, same problems
Here i use a tplink WR1043ND, has good signal, and i use with b/g/n - WPA-PSK/WPA2-PSK with AES sec key.
If i change to another encryption, its gonna work better ?
I bought this device last week, and if i cant use wifi security and have problems like that, i will be forced to return to the seller
tks

nah, in here we discuss about the HP kernel not stock kernel. in stock kernel the wifi module will be okay and it support both wpa-psk or wpa2-psk

Hi
Ok, so i guess its a problem with the device
Anyway tomorrow i will return it to the seller and get another one
tks !

ow, so you are on in stock right now if i'm right. yeah you should return to the seller. or maybe you want to flash with CM7.1

Hi, will install CM (already had on my defy, but the device broken)
The problem is that the lg2x lost the touch, so gonna grab a new one, dunno if it was a hardware problem or just a problem with the flash

What is the CM9 issues and how do you guys survive with it ?

Hi , anyone can tell me the exact CM9 issues and why it's cannot be fixed yet ?
So how you guys survive with that ROM ?
Please share me some TIPS .
Currently i'm using Stock Gingerbread since I bought it last year December and now I would like to use CM9 custom rom (PARANOIDANDROID) yayyy
Thanks .

I guess the idea is to test your own skills in modding your phone and see, what the different developers would like us to have. After a few installs, you are hooked at getting your daily fix of new ROM and will suffer withdrawal symptoms, if no new ROM are a available for even a short period!!
Even if all the latest ROMs are not fully functional, they still add many new features to our phone.
I have become very enthusiastic about my phone again and I have had it for almost two years now. The longest time I have ever had a mobile phone.
What also is interesting is that you are able to try so many new apps, that only works if your phone is rooted.
So the benefits are many and if you are not satisfied, there are very good guides on how to go back to stock.
Good luck

CM 9 don't support Hardware acceleration. Thats the major problem that i know

Hardware Acceleration in CM9 for LG O2X is not working as of now (Needs LG to release an ICS based kernel).
Due to which:
- Video Recording doesn't work.
- Will not be able to play HD videos.
- Some of the system apps will start to lag after some usage (Phone & Contacts).

thank you . i hope the promised official ICS update will reach soon .

Ok, so CM 9 and CM 10 has the following problems:
1) No Hardware acceleration which means:
a) You CAN'T use your video camera at all. Now, I know that some says that you can use Videocam illusion, but that app can record only very low quality videos, which I found to be pretty useless (a lot of CPU use for that low quality).
b) Google Chrome is not supported due to it's need to access the GPU, but this is not so important due to other very good browsers
c) You will experience scrolling jittering. That being said when you will try to change between photos in the gallery (usually there is the bigest problem), or between songs in some media players by swaping on the screen, you will see something like the photo or album art is going back from where it came, but the result is good: changing the photo / song. The only problem is the visual one.
d) Gameloft games, and especially those with a little video at the begining will not work until you delete those clips from the instalation folder.
2) No radio application => no more FM radio for you. Wi-Fi (or a really well data plan) resolves this thing by using it for Tune-in Radio, a very good application for radio. I prefer to use it even on GB roms, because of the very good sound quality regardless the standard radio that sometimes loses the signal.
3) On CM 10 there are a few more bugs like no automatic brightness, or battery drain due to Wi-fi. Regardless all theese bugs, I found CM 10 from ParanoidAndroid to be a way much better rom than any other around here. Keeping the Wi-Fi off I don't experience any battery drain (more than that my battery last longer than anytime) and my favorite no data connection lost (I don't know if this was a carrier problem or not, but before switching to CM 10 i had a lot of data connection problems).
4) Not to be forgotten the lag on installing applications from Google Play Store. I found this problem on almost every single rom I've tried, and I tried almost all of them. I think I found only one or two roms w/o this problem, but being a maniac for the latest updates I've chosen the ICS and JB roms instead of a very stable one
5) No GPS working on CM 10
Now it's your decision. If you can live w/o video camera and gps and try to not get angry at every scroll bug you should really try the new CM 9 and 10 roms

I know this may sound weird to you, but: I can survive without any ROM.
It's not that your life depends on your smartphone, does it?
Just be happy with what you got.

gt-p1000 gps problems

hi all,
I was just wondering if I was the only one with gps troubles.
I tried stock rom, overcome, ics miui, jb aokp, but rarely got satellites detected.
I once got some connexions while using tomtom but about 20 minutes (discontinued) on a 2 hours trip.
with some test apps I got 3 feeble satellites signals.
Does someone else had so much trouble ?
(I trying some gps fixes I found but just wanted to know if I was the only one)
thanks

you are not the only one

No you are not.
Did you GPS work at all?
Mine did and then stopped.. here is what I did before it stopped.
I rooted it with ODIN (ages ago)
for ICS I followed the widely available instructions to get ICS (How to install Stable ICS 4.0.4 on Galaxy TAB P1000 [CyanogenMod 9 Stable]) and everything worked well. Needed a different camera app but the GPS worked reliable and FAST.
When JB was available I used the ROM Based on Jelly Bean 4.1.2 Platform. This is the official CyanogenMod 10 Nightly but had issues with Gapps and did not have time back then (xmas time) so just restored my nandroid backup. And to be honest I have no idea if the GPS worked after that. I think I used the iPhone more for GPS stuff until March.
Fact was it did not get any satelite at all, only location is via WIFI.
My hypo was that I may have missed something or the nandroid backup / restore does not include all files.
To fix it I looked for a later ROM and used JB. I used the Android 4.2.1 CM10.1 for Samsung Galaxy Tab 7 P1000 [Filename: cm-10.1-20121229-EXPERIMENTAL-p1-cdesai.zip] and Google Apps [Filename: gapps-jb-20121130-signed.zip] and that rome is reported that GPS works (but remember it did not work before i used this rom)
All went well and the rom works with all other features but did not GPS and I still have 0 satelites with either GPS Test or GPS Fix.
That is when I found your post.
I had a good dig around XDS and well GPS issues are plentiful, but not quite like the one you or I experience.
It seems that you at least get "some" satelites which is an improvement over none.
re-stocking did not solve it for you so I may save myself the trouble.
that said, my only thought is the GPS module packed in and that is why I get not a single satelite...
did you get anywhere?
TIA

hi there,
for my part, I bought this used tab some month ago. I didn't really liked it in gb, so almost immediatly tried to root it, changed recovery and rom, but never tested gps then.
I actually use miui ics rom and tried gps once. on a 2 hours long trip, sunny weather, nothing to disturb gps signal, I had 20mn of signal and not in a single straight connexion, but only just 1 or 2 mn from time to time.
I tried restock, but not bettre, even my chinese tab is more efficient. I'm still trying to understand and looking for answers but I nedd to restart my searches all over, too much things founds and now I'm quite lost.
The only thing I remember is that someone picked up gps files from his old samsung gsm and copied them on his GT as they had the same system.
I'll try to find that back, and maybe I'll try with my htc as they're all two on miui.
I'll send infos if I find something working

The same problem

Sorry for my english!
My GT-P1000 was to repair because it was unable to read the internal memory! After that I never tested the gps and rooted the tab with CM10.1 TWRP 20130802 Kernel 3.0.88 v1.35 (cm-10.1-20130802-UNOFFICIAL-p1)! I tried gps, but there is no gps signal and there are no satellites found!

no, still not solved it, I suspect some hardware problem like gps chip dead, gps antenna unplugged or broken, but as I had troubles with electronics thèses days, I will wait to open my GT

install apps like Faster GPS, GPS Fix or similar from Play
define your NTP Server and load XTRA data (table of current satellite position)
this will help you!

Hello. So Ive been having problems with the GPS. Sometimes i let it search for more than 20 min. and no lock. Sometimes GPS is not starting at all, I have to power off the phone, sometimes I need to start bluetooth then GPS so it can get a lock... thats wierd right?
Im on stock rom 2.3.4 V20q with HP kernel.
On CM 10.1 android 4.2.2 I get GPS lock in max 1-2 min. but on stock GB no...
My question is: Is there any FIX?

GPS is via satellite and not via Internet

I wanted to say that I want to use the GPS without needing to use the internet first.

Run the App one time.
It only sets the ntp server.

Nah... same fukin thing again... it gets signal.. but...
I use Navigon... it gets the signal but after 3-4 sec. it loses the signal... then gets the signal back.. but after 3-4 sec it loses... WTF I hate this stupid phone.

Try a different kernel. This may be an issue with HP kernel.

Hi everyone,
I've made a GPS fix for LG Optimus Black (P970) and I wanted to share.
So far, I'm getting good feedback. If you want to test it, go here: http://forum.xda-developers.com/showthread.php?t=2205560
Since I only have a P970, I can't test on other devices. If you want to test this, make a nandroid first!
