I lost GPS after updating to Oreo - Moto Z Play Questions & Answers

Greetings. I decided to do the update manually to Oreo. Everything works wonders except for GPS, no application detects my location. It's already restored from the factory and in Nougat it always worked well. Can someone help me solve the problem ??? I have the bootloader blocked. Thank you very much.

GPS problem after custom firmware

Hi all,
I am a little bit desperated about getting my gps on my LG g3 (D855) working again. Until last month my GPS worked just okay, something it was way off but it was workable I was on stock lollipop after the OTA upgrade from Kitkat. Because of some heating problems and huge performance problems I decided to try a custom rom to see if there was increase and it worked perfectly! I noticed that my signal reception was a little bit troubling and flash some other modems to see if it improved ended with the 20p which was okay After that i tried my gps... and it wasn't able to fix anymore when wifi is on it sees 23 gps in view (GPS Test) but all with "00" signal. When turning wifi off it went back to 9 and sometimes 0. I checked the forum offcourse and found a few solutions:
-Erase modemst1 and 2 by using fastboot, didn't work
-Kitkat stock firmware, didn't work
-Lollipop stock firmware, didn't work
-Exchanged Simcard, didn't work
-Use Top NTP other program which configures gps.conf to the right NTP server, didn't work.
-Recalibrate Compass.. calibration worked but gps doesn't
-Try turning off location service, rebooting device, turning it on.. did't work
-Trying gps only or the with google services, didn't work
-Flashed almost all available modems, all the same results, 0/23 satellites and no gps fix
-Let is tryed to find a fix for like a hour but didn't work.
-Tryed latest CM firmware and Blissrom roms but all the same results.
Do you have any solutions or ideas what might be wrong?
Thanks in advance!!
Kind regards,
Toby
Open GPS Test, press the Menu button, select Update AGPS and try again.
Dear Robogo1982, Thanks for your reply! I tried it but seems not to work i also tryed the clear function and after that the update.
Try it in Flight mode.
Tried it, even with sim removed. It also seems that gsm reception is a lot worse, could it be a mechnical problem?
Flash back to stock using KDZ

US991 Upgraded to Marshmallow and now mobile data doesn't work

I am using LG G4 US991 in Canada. It is unlocked and i am using it over Fido. With Android 5.1 I had no issue, everything was working smooth. Then i got the marshmallow updated and I had following three issues
1. Mobile data plan isn't working .... I used this link to configure the APN http://www.fido.ca/consumer/content/configure-unlocked-device-guide but no success. I factory reset the phone, restarted and tried whatever i could but still same problem ... Is it a known issue ? Is there a fix ?
the other 2 issues aren't that important as of now. Heating up and battery drain. I can live with those as long as my data starts to work.
P.S: The wifi is working with no issue.
Having this same issue but no luck in finding the procedure how to downgrade back to lollipop. My software version US991120c and it is a US cellular phone.

Thanks for letting me know. Seems like i am not the only one. Please let me know if you find something and I will let you know if i find something.
I am also having the same issue. Only wifi works, but no data connection.
Any news with this issue?
still no data connection for me.
Same issue for me, any known solution?
i am in italy & using us991 ... i also update to Marshmallow & facing same problem.. i try many things but no luck.. i think we have to wait for root this version first then problem may be solved ..... & try to downgrade can hard brick this phone .........
Did you fix this problem?
I just go the Marshmallow update and now my data is no longer working.
APN seems fine...
Hey
I'm in that same situation but I'm with Rogers. I did a factory reset, ttriple checked my APN, tried non LTE APNs, no luck.
Everything worked before the MM update.
Did you find a fix??
same issue. is there any way to downgrade?
I had the same problem on Sprint after taking the OTA. Here's what worked for me:
Connect to wifi
Go to system settings> system update
Tap each of the categories and wait to receive a pop-up saying it's completed before tapping the next one.( update PrL, update profile, etc) after each one is updated. Reboot and toggle wifi off. Mobile data should return. Again this worked for me on Sprint, I tried apns and reset to factory and nothing worked till I tried this simple approach. I am all stock, never rooted or forced an OTA. Let me know if it works or not for you
i'v found the solution.
here is a link for fix

GPS issue with lollipop

GPS won't determine location even after is on. already checked with GPS checker and still cannot retrieve location. i encountered this issue with all lollipop roms and RR marshmallow rom even with the official sony lollipop firmware. the only rom that works with GPS is CM11 nightlies. I already ran the service test for GPS and purge assitance data, but still no results.
I will appreciate suggestions of what the problem might be and how to fix it, thank you

Device forgets all saved WiFi passwords when toggling it off and on again

Hello guys!
I have weird problem!
I got broken OP3 A3003 (64gb model) and repaired it. It works perfectly but there is just one annoying fault that i cant seem to find answer to. The WiFi will not reconnect to saved hotspots after i toggle it off and back on again. Everytime i must give the password again and again. after i connect it works perfectly an no hiccups at all. just the reconnecting not working. I can see the saved network in the list but deleting it does not work. I havent yet rooted, im on latest stock and the bootloader is locked. Tried factory reset but same problem occurs.
Searching web and Oneplus forums pointed that there is couple others having same problems but no solution from anyone.
Do anyone have had any of this kind of problem and how did you solve it?
I like Oxygen OS itself but rooting is a must! after i can give logs or stuff if needed!
Update to latest oxygen os or open beta, if updating won't fix your problem then perform a factory reset.
Like I said I tried factory reset but did not help unfortunately I updated to open beta 38 last night but did not help either. 'm gonna try open bootloader and flash the firmware again completely and see.
