Ok, we have numerous reports of GPS not holding lock after upgrading to Honeycomb.
This thread is for the purpose of identifying the resolution to this issue.
To begin with I'll start with asking for details from those of you who are encountering the issue and also those who are not.
What I want to know is, what software you were running and also exactly how you got to that version. For example ist is not sufficient to say you did my S-OFF upgrade, I also need to know the device (wifi or 3g) and version of the upgrade you used and whether you switched from a different version of the software to your current version.
For example, something like this:
Not Working: US Wifi Flyer, S-OFF, originally upgraded with the WIFI package built from 3.55.405.1 3G package, re-flashed with the US wifi OTA.
Casual observation seems indicate that it is all or mostly Wifi flyers that are affected.
Had trouble with my US Wifi Flyer, S-OFF, originally upgraded with the WIFI package built from 3.55.405.1. Updated that to us OTA package and still had trouble.
Started all over downgraded to GB then went straight to Globatron’s latest (the big file)
Working now

Thanks, this is consistent with my working assumption which is that it affects WIFI flyers that were flashed with the 3g ROM.
I have the US wifi flyer. S-Off, installed the 3.55.405.1 3G package followed by Leedroid rom. GPS was no good. Went back to the 3.55.405.1 3G package (from nandroid backup) and GPS no good.
Then installed the US WiFi rom. GPS is fine. Installed Leedroid and GPS is still fine.
hi globaltron,
US BB Wifi Flyer, S-OFF, originally upgraded with the HC WIFI package built from previous RUU_flyer_wifi_B10.zip, then installed LeeDrOiD HC V2.1.0 but GPS satellite lock wont stay on (dropping signal), tried all agps patches no go. Finally flashed new RUU_flyer_wifi_BBUS.B10.zip (2x) just to make sure over leedroid rom still the same results.
GPS Dropping
DEVICE: UK WIFI FLYER, 16GB
NOT WORKING: S-OFF, 3.55.401 - roms tried: LeeDroid, WestFire, Globatron's B09 (originally upgraded with the WIFI package built from 3.55.405.1 3G package)
NOT WORKING: S-OFF, 3.55.1114.31 - roms tried: HoneyPot, Globatron's B10
WORKING: S-ON, OTA 3.55.1114.31 (updated from Stock GB)
Also, worth noting that I (may) have experienced bluetooth problems. I use a OBD2 bluetooth adapter with my car and Torque App was having none of it with HC custom roms (including B09/B10). Basically, it connects to the OBD2 adapter, but but never negotiates the protocol. Works fine with GB and HC OTA. I could be alone on this since I don't trust the OBD2 adapter.
Navigation apps I use: CoPilot 8 & 9, Google Maps.
[QUOTE
WORKING: S-ON, OTA 3.55.1114.31 (updated from Stock GB)[/QUOTE]
so, with S-ON no GPS issues good to know. I have been trying to find a fix with no avail. I'm S-OFF US HC wifi rom.
no, it's not hboot.
My observations using the GPS Status app.
DEVICE: US BB WIFI FLYER, 16GB
Working: GB stock rooted & GB Leedroid
NOT WORKING: S-OFF, 3.55.1114.31 All configurations below
1. Globatron's B09 (originally upgraded with the WIFI package built from 3.55.405.1 3G package).
2. Globatron's B10 Cross-grade from Globatron's B09 Wifi
3. Globatron's B10 full clean install of US Wifi RUU over Globatron's B09 Wifi .
Not tested : HC OTA update from GB
Setup: Turn off screen timeout. Open GPS status or another app that uses GPS that shows you status constantly.
Symptoms to watch for:
GPS turns on and locks quite fast, first time will stay locked for 30 - 60 secs. Then it loses lock and starts searching, Acquires lock again in a few seconds, then loses lock again after about 10 sec. repeats the loss of lock from this point acquiring and then losing lock every few seconds.
Tried clearing AGPS data and re-downloading, no help.
Referring to DigitalMD's post above
I have the BestBuy WiFi 16GB Flyer
I purshed it stock and took the OTA HC update.
Over the last two days I have since Rooted S-Off and am running Globatron's US Wifi RUU build.
Before I rooted my GPS did not maintain lock. It was symptomatic like your findings.
After I rooted and flashed HC, GPS was still symptomatic.
I have since edited the /system/etc/gps.conf folder.
The first string of text by default is:
NTP_SERVER=north-america.pool.ntp.org
I have changed it to read:
NTP_SERVER=us.pool.ntp.org
I used Root Explore and long pressed the gps.conf file and selected open in text editor. Make and save changes and reboot.
Having owned the HTC Thunderbolt, that device was plagued with similar GPS issues and this was a fix that was offered up in other threads here at XDA.

thanks, will try this now.....
Have you tried observing the actual status using a GPS status app? It may relock fast enough to satisfy some programs like Google maps and navigation even if it unlocks every few seconds.
Confirmed:
Monitored the GPS lock through the GPS Status App.
I have kept a solid lock status.
Theoretically that should not be enough to keep it locked , but might help achieve first lock faster. This is a strange problem so I don't know whats going on.
edited gps.config to NTP_SERVER=us.pool.ntp.org same results no go for me.
could it be a possible power saving related issue?
NOT WORKING:
1.Lee Droid
2. Globatron's B10 full clean install of US Wifi RUU over Lee Droid.
Not tested : HC OTA update from GB
Setup: Drive around with Flyer. It loses GPS consistantly every 1-2 minutes.
Symptoms to watch for:
GPS turns on and locks quite fast, first time will stay locked for 30 - 60 secs. Then it loses lock and starts searching, Acquires lock again in a few seconds, then loses lock again after about 10 sec. repeats the loss of lock from this point acquiring and then losing lock every few seconds.

Could someone try this for me … open the locations app and allow it to find you. Wait for the GPS icon, at the bottom to disappear, exit that app and open GPS Status … see if you maintain lock
A-GPS as cause?
Maybe I overlook it but what I see, is the problem a 3G ROM on a WiFi version. I am not an gps-expert but is this not normal because we have a A-GPS which is using also 3G and WiFi signals for a proper GPS signal?
I will check this theory and maybe it has nothing to do with the ROM-Version but with the build.prop and other specific GPS stuff which expect a proper 3G.
PS. And yes, I am no fan from removing some phone apps to have a WiFi-version. This is dirty and I am not sure but maybe this problem is the outcome.

As you said, A-GPS or Assisted GPS relies on a data connection to acquire some satellite information to make the lock faster. Therefore, it makes sense, if it was not as stable with out a 3G connection on the move.
But then again, whats confusing is that, it is stable on gingerbread, at least for me. but not on Honeycomb. i'm always tethered to my phone on the move, so A-GPS should work normally.
*EDIT: I forgot to mention, it happens on both the 3G HC ROM and WiFi HC ROM.

I posted of wifi issues with radio 3.35 and rom 3.0.0 in post #648 in this thread: http://forum.xda-developers.com/showthread.php?t=376150&page=65. I want to mention that I finally resolved the problem. It looks like it wasn't the ROM update at all but rather the result of running WMWiFiRouter. I removed this program and my wifi functionality was restored. I then replaced the program with the latest version and, while it worked properly as long as nothing went wrong, I was able to get the wifi problem to come back by launching the program with the hardware wifi switch off and then turning the switch on while WMWiFiRouter's connection sequence was in progress. In this last case, the program's built-in crash recovery was able to get wifi working again (although that hadn't worked back when I first posted the problem). So, I think I'm good as long as remember to always have that slider switch on before launching WMWiFiRouter and to make sure the program disconnects completely and fully before exiting the software.
I sincerely love the 2.1, and i really appreciate the work and effort the dev´s are putting into the rom´s that are available free of charge.
But i cant find a rom that has working GPS on/off feature, everyone i tryed so far requires phone reboot..
so i wonder, why is it so hard to enable GPS without reboot?
and are there rom´s that have working GPS?
i tryed to raise the issue in some of the rom specific forums, but it appears to be a less prioritized bug..
For me I found that re-flashing the latest radio rom after installing 2.1 got GPS working as it should do.
apart from what klutsh said (which i can't reproduce btw), there is only one kernel available that works with the 2.1 leaks, and that kernel has a bad gps implementation.
androbin beta r2
with androbin beta r2 i use gps and work very good, without problem.
fix is quick, stability ok.
last week i try it with ndrive, cca 160km trip, without problem.
Yip I can confirm Switch on your gps, and wifi (just for the hell of it, not too sure about this part) reboot into recovery, flash the latest radio, reboot and all should be well.
I can confirm the opposite; switching on GPS, wifi and bluetooth, flashed new radio and booted up the phone.
turned off gps and rebooted, then enabled gps again (without restart).
still no gps reception.
using villain3.4 atm, but this has been persistant thruout all tested 2.1 roms.
None of the Villain Roms worked ever with GPS for me, but BeHero+ V1.2 is the first 2.1 ROM where it always does, and it even to a very fast GPS fix!
im trying androbin atm, havent yet gone outside (still downloading my apps over wifi), so i cant say if it works or not.
but i really think the devs should pool their resources/projects instead of releasing 15+ similar roms
I've never had a problem with GPS - used Navigator to get me home with voice navigation the other day (i knew the route but still) it was awesome
I would also like to know the definitive answer. All ROM's released are with working hardware lists including of GPS and no mention of prossibility of bugs but going through the replies, it seems like mixed reactions.
1) ON/OFF reboot bug?
2) Sleep mode bug with any Radio?
3) As quick fix as in 1.5?
4) Not inconsistent ie fixed once but struggle next time?
Kendong2's reply seems to suggest NO. Is it ?
I have the WiFi only Flyer and I am running the offical leaked honeycomb ROM and I noticed that cell standby was back yet again. I have fast boot disabled as well. Please someone fix this, it is getting VERY annoying.
Is this because the leaked version is GSM based? It's possibly the radio software is causing the battery drain on the wifi model(???) . Just a guess though. I remember dell streak owners going through a similar thing.
I apologize if this theory has already been debunked or addressed. Haven't been following the development thread.

Well I had the issue with LeeDroid 2.3.4 so I disabled fastboot and that fixed it. However fastboot is already disabled on the honeycomb ROM.

Leedroids (awesome DHD dev) is GSM based too I believe. Did you experience the cell standby on the stock wifi rom?
If you're running Globatron's version you may want to try his development thread. I understand the support has been awesome.

If you are running the latest HC from GLobaltron, you should not see this IF.
at the start-up initial screens you picked Wifi only, NOT wifi / 3g when you selected your language, Google account etc. If you did not do that correctly, then the Flyer is trying to initialize a non-existing 3g radio. You might have to reset to factory default and go through user setup again.
I know that I chose WiFi only. I didn't have the issue in stock gingerbread ROM. I did use Globatrons method.
I'm on GLobaltron's leaked official HC and at first everything was great. Standby battery is fine, no mobile network. After installing some apps (I feel Skype might be the one to blame) I suddenly noticed that Cell network (whatever it is called in settings) was eating battery on Wifi only Flyer. After some research I got to several fixes:
1) Disable Fastboot (was already disabled)
2) Open Calculator and punch in !+!+4636+!+! to get to the setting and turn mobile network off. For some reason that thing doesn't want to stay off on my flyer. I'm suspecting some stupid app is doing something wrong there.
3) Open up Root Explorer and delete/move/rename phone.apk, telephony..apk and mms.apk.
After some screwing around with this, my Standby Battery run time is back to normal. For some reason "Mobile Network Signal" shows yellow (in battery info) instead of not showing anything like before. Well at least it isn't Red anymore, like it was when I was having problems (I guess because it was actively looking for signal). I usually turn Wifi off when screen is off, and last time I checked it Flyer lost only 1% of battery during 9 hour night sleep (from 100% to 99%) which is OK in my book.
I try to delete them in File Expert with root permissions and they don't delete.
If you have a wifi only Flyer and the HC latest root ROM, ( the wifi version, not the 3g version ) is installed you should not see any 3g signal bars. So I suspect you installed the wrong version perhaps.

I don't know about OP, but I personally have installed Wifi only version on my Wifi only Flyer. I didn't see any bars, but when my Flyer was misbehaving I went to battery stats and have seen Cell standby (of something like this) eating battery. It showed something like 10h (or whatever time it was disconnected) on battery, 100% without signal. And once again, I didn't have that issue right away. That issue came up after some apps where installed. I have tried to track it down, but after some time didn't feel like dealing with it anymore and just renamed system files. It fixed my issue.
My Wifi only Flyer on Wifi only ROM shows Mobile Network Signal in battery stats as a Yellow line. Have no clue what that means, but at least now it doesn't drain my battery.
I did download the WiFi only ROM. Tried using the calc trick, and it was working fine for a bit then the radio was on again.

Mikey, try flashing this from recovery:

I already downgraded. I prefer GB personally.
Hi, I bought a Motorola Atrix in Amazon 2 months ago. Since start the Gps din't work at all, 0 in view in apps like "Gps test". I tried almost everything: changing gps.conf, flashing radios, using custom roms like Nottachtrix and CM7, and reverting back to stock via rsd. Btw, a friend of mine who bought the same phone at the same time, had problems with gps in stock rom, but after flashing CM7, it worked just fine.
So, I ask you to help me giving any ideas to fix this.
Maybe this can be useful: The Atrix came with Italian retail rom and N_01.100.00R radio.
Thanks a lot.

If you use an app such as GPS status do you pick up any satellites? It seems to be a common problem to find the satellites but not to be able to get a lock.
Also is you install GPS Status it will allow you to update the agps files.
Did you try gps lock with data access enabled? And as eddhard said do you pick any satellites?
In the gps settings menu turn OFF the options to use mobile networks or wifi. Then use the gps status or gps test app outside in a clear view for a minute or two. If it reports an accuracy distance as 0 or an error there is an issue with your gps that I might have a solution for.
For no reason my gps straight up failed to get a lock. In the test apps, it would see 9-10 satellites with strong signal but never wanted to get a lock. Multiple multiple factory resets, formats, any other variable I tried to change and the issue persisted.
I've attached the file that fixed the issue for me. Extract the libnmea.so and place it in your /system/lib folder after you make a backup of the existing file. Let us know if that helps.

Thanks for your answers, the problem isn't the locking of any of the sats. Test apps show "0 in view" even on outdoors.
I don't have a solution. But I've had a lot of difficulty with GPS on my Atrix as well. I can get a lock usually after a minute or so, but then the GPS would go to sleep. So if I'm moving or logging a route, it'll show me where I started even after several minutes. I flashed radios, updated gps conf, and used GPS Status & Toolbox to get a lock. Still no improvement. It helped me get the initial lock, and didn't resolve the freezing issue. I eventually gave up and bought separate GPS. So I'd be interested to know if you find a way to fix this.
Guys, if you don't see any satellites in GPS Status app, maybe is hardware issue. If you have warranty, use it. If you don't, try to disassemble your phone and look. Maybe just cable is disconnected or has bad contact. Of course be very careful with disassembling or ask someone with experiences. Youtube guide how to change digitizer on Atrix could be useful.
Good luck
I had problems with GPS fix on AT&T atrix 4g with N_01.100.00R europe radio. After flashing 37p at&t radio gps works perfectly, fix is really fast.
Also WiFi signal strength increased.
Hello everyone!
This is my first post and I apologise for my english
I have very big problem with GPS connect. I was trying probably everything and I haven't idea how to fix it.
To the point: when I'm staying in one place and not moving, GPS fixing in few seconds. But few minutes later (1-2) or when I move few meters, HOX+ losing connection with sateliltes and not want connect once again.
I was installed GPS Test and is seeing some satellites, but not want to fix or connect is losing in few minutes.
I was installed: GPS Test, GPS Fix, Faster Fix and nothing. I was installed Venom ViperX+, Revolution HD and still the same. I tried this trick ( YouTube v=NfH48nbCFE4 ) with GPS antenna but isn't better...
My HOX+:
Rom: Venom ViperX+ 2.0.3 (on 2.01 and 2.0.2 was the same problem)
Android 4.2.2, Kernel 3.1.10-g7f360be, Hboot 1.72, Radio 3.1204.171.33

I dunno but try changing kernel, i use elite kernel... i had the same rom but changed it due to lag d)
Which apps that you use have problem with GPS connection?
I remember I used a speedometer tool on my HOX+. After turning on, I waited few minutes for gps signal. It stayed on "waiting for gps fix". But when I opened Endomondo, this fix came immediately.
Maybe it really depends on the app that uses GPS.

I have problem on any app - Google Maps, Google Navigation, Sygic, GPS Test, GPS Fix, Real Time GPS Tracker and few others.
Now I'm making backup's and I will try change kernel...
EDIT:
I flashed Elite Kernel and still the same
Tommorow I will try to install another ROM, but I slowly losing hope...
It's possible that some app "blocking" or something wrong doing with connection?
Edit 2:
OK. I installed Revolution HD and was the same. Flash kernel to Elite and still nothing better.
I returned to ViperX+ with "standard" kernel, I opened phone and "improved" GPS antenna and.... is better! More satellites, faster fix, better signal, but still sometimes losing connection for few seconds (and connecting again which earlier was impossible)...
