Vkworld Vk700 Pro - GPS can't get FIX - Upgrading, Modifying and Unlocking

Hello,
I have a Vkworld Vk700 Pro. I rooted the phone with Kingo Root, got 3 GB for apps but can't make its GPS working properly. It can't get GPS fix. I installed most of apps from the Google Play that can change GPS settings (server etc.) and still no results. The phone is not downloading EPO files when I press download button even when info "all rights are granted" pops up. Maybe this is why GPS can't get fix? I was also trying to replace GPS file gps.default.so but still it didn't help.
YGPS informations says: Chip version: MTK_GPS_MT6582; MNL version: MNL_VER_14011701ALPS05_3.60_06; Clock type TCXO; Clock buffer UNKNOWN.
Please help!

[Q] Bada 2.0 S8500 GPS location Problem after Upgrade 2.0

Bada 2.0 S8500 GPS location Problem after Upgrade 2.0
Dear Friends,
i am facing problem in Location Service/GPS system my Bada S8500 after upgrade Bada 2.0. It's not working.
Please any one solve my problem...
If you just upgraded from bada 1.x to bada 2.0 and and now have problem with Navigation (Route 66), do this simple setting:
1. Setting => Location =>Location service (set it to on; i.e. green colour).
2. Back to main menu, launch "Navigation" (allow it to run for few seconds)
3. Then click on "More" (on Navigation menu) => Contents (download contents for Navigation, to sync your license; download maps; and download any other contents you have purchased e.g safety camera, etc).
4. That's all.
NB: In case your problem is not with Navigation (Route 66), please do well to explain in details what problem you are facing.
All setting is enable....
Actually i download foursqure application in my device. when i going to use 1 msg appear on screen..your loction could not be found. verify your gps setting and also the same problem with other apps.

Normally when you install any location/GPS app manually, you need to also activate/include this app in the location service manually. Otherwise you will always receive the said error of 'Location service is disabled'
For Example, I installed the GPS Status app.
When I tried to start the GPS, it displayed error of 'Location service is disabled'.
Yes, even if I have enabled location service in my phone, but I have not enabled it for GPS Status app.
To solved this, I go to Setting => Location => Location service (already set to ON, if not, turn it ON),
then on same page/menu, scroll down to bottom of page where you will find your installed location/GPS app (in this example, GPS Status), and turn it ON.
Now go back and launch your location/GPS app, and it will no longer display the error. It will now work.

[SOLUTION] [I927] GPS fix in Poland

Hello,
i try many solutions to fix GPS in my I927 (orginal AT&T ICS rom): first GPS Doctor from Google Play store (no results ), then i root my phone i try change gps.conf in etc folder. I try many gps.conf configuration - still no effect (GPS fix 4-5 minutes). Finally i got idea... My Wife hat Samsung Galaxy S Advance from polish distribution with polish clear JB ROM (updated by Samsung kies). I try copy with my Wife's phone files AGPS_CA.pam, GPS.conf and SIRFGPS.conf to my phone....
and it worked :victory: Now i catch GPS fix in 7 sec.
SOLUTION STEP BY STEP:
1.You need rotted I927 phone (soluition in this thread)
2. copy from my PC files AGPS_CA.PAM, GPS.CONF and SIRFGPS.CONF (files below) via Bluetooth to my Phone
3. i copy with Root Browser from Google Play (may be any Root Explorer) files AGPS_CA.PAM, GPS.CONF and SIRFGPS.CONF system/etc folder (overwrite -> yes)
4. i turn on GPS Doctor (I bought this earlier) click "Manual Fix Option", then "advanced operation" and i cleaned all the items one by one (Clear Almanac Data, clear Ephemeris Data ....)
5. I turn off my phone (no reset - turn off) and go outside my house to place in which there is an unobstructed view of the sky
6. I turn on my phone and run GPS Checker from Google Play (i downloada this earlier) and wait for FIX (this take 149 sec.)
7. tur off and turn on GPS Checker and now i catch Fix in 7 sec. :highfive: i turn on Google Navigation and i catch fix
also in a few seconds.
I think that SIRFGPS.CONF is very important for the proper functioning of the GPS.In my opinion GPS.CONF does not play a big role here (as You see in my files ntp server is still set to north america)
I hope you GPS work now properly.
greetings.
P.S. Sorry for my english

Anyway, good steps, I may have to look into SIRFGPS.conf as I'm also having problems with GPS.
Ja uzywam fastergps i rowniez szybko sie laczy.
Sent from my SGH-I927 using xda app-developers app
However, the correct settings NTP help ...
I decide to try my device in the field.
I turn on GPS .... and got FIX (in gps checker) after 106 seconds.
Also i change i GPS.CONF ntp server to polish and put GPS.CONF in to system/etc folder and repeat steps 4 -6
4. i turn on GPS Doctor (I bought this earlier) click "Manual Fix Option", then "advanced operation" and i cleaned all the items one by one (Clear Almanac Data, clear Ephemeris Data ....)
5. I turn off my phone (no reset - turn off) and go outside my house to place in which there is an unobstructed view of the sky
6. I turn on my phone and run GPS Checker from Google Play ... and wait for FIX...

First FIX take 4-5 minutes, but now i catch GPS Fix in 15-30 sec. i try this in random places in my City (distant from each other by about 5 km).
Now i have visible 6 - 11 satelites and fix catch 4-7 satelites.
i think now its all good.
I changed the gps.conf file in the package for the Polish ntp settings. But anyone can edit in GPS.CONF the ntp for your country
LIst of NTP servers You can find in official NTP POLL PROJECT
This solution works for ICS ? You wrote that you took sirfgps file from JB phone.

Hi,
some time ago i turn on GPs in my I927, nad have no response. GSP not turn on.
I realized that it was caused paths to folders. My settings were wrong:
UART_DRIVER=/dev/ttyAMA1[/B]
RESET_GPIO=/sys/class/sec/gps/GPS_nRST/value
ONOFF_GPIO=/sys/class/sec/gps/GPS_ON_OFF/value
Click to expand...

I changed the settings in the original file sirfgps.conf from I927 to the same as in S Advance, but I left the original path:

RESET_GPIO=/sys/devices/virtual/sec/gps/GPS_nRST/value
ONOFF_GPIO=/sys/devices/virtual/sec/gps/GPS_PWR_EN/value
Click to expand...
Click to collapse
Now GPS work fine, catch FIX ~15 sec. but always before i use GPs i restart first phone. I think that sometimeswhen i use Task Killer, some GPS process is off.. Anyway reset phone, start gps and this is OK.
I change file to download to new with rigth settings.

D855 Lollipop - Unable to download applications/files/whatnot

Hi,
I've been troubleshooting this issue for over a month now and I'm running out of ideas... I'm having an issue where I can't download anything to my device, it just stuck on "downloading" with 0% in the progress bar but if I'm restarting the device it will suddenly work for a few minutes - so I have to restart my device every time I want to download anything.
I've taken the following actions:
- Factory reset.
- Setting --> mobile data --> verified "restrict background data" not checked.
- Google play & Google services: clear cache, return to older version.
- Checked it on WiFi only/Cellular data only.
- Free space in my internal storage is 22GB
The problem is not just for one application, it will not download updates for LG software and not even regular download from the internet. From what I checked it looks like upload is working at all times.
Software Info:
Android version: 5.0
Android security patch level: 2015-11-01
Baseband version: MPSS.DI.2.0.1.c1.13.2-00002-M8974AAAAABPZM-1
Kernel version: 3.4.0
Build number: LRX21R.A1447078419
Software version: V21a-SEA-XX
I'll really appreciate any help
I'm not sure if you have root, anyway, try to deactivate the google play services and google play store, reset the device, turn off the internet, activate both services, reset the phone again.
If it doesn't work, i believe all you can do at moment is download in the internet an apk named "blackmart", got the same apps in play store.

Thanks for the quick response! Do you think that the actions you've mentioned will help even if it won't download from chrome or from LG update? Your solution seems to take into consideration only Google play download issues. right?
My fault, i thought it was just in the Play store, I don't know what to do then... But i'd try to use Blackmart as i said before, if you have a pc/notebook, download the apk file and transfer to your phone, then install it. Hope it works.
Install uc browser then try to download anything its have default downloader...just try if it works

Tried that, still doesn't work... Marshmallow update seems to be my last chance, getting tired of this phone

Firmware Update to Marshmallow - GPS Stopped Working

Hi!
I've made a post in the Asus forum, with no luck and I found this page where you seem more technical :
Two days ago I downloaded the Android MM 6.0 update from the Asus Homepage downloading the version WW-4.21.40.144 , since I live in Brazil and the phone was bought here. I followed all the steps one by one till it got updated.
The problem is, since then my GPS is not working (Waze, Googlemaps ans several apps).
I tryed:
1. Giving all permissions of location to the apps
2. Puting the settings in High Accuracy
3. Restarting the phone several times.
4. Switch on and off Airplane mode and 2G 3G ands 4G (I read sometimes its interference from that)
5. Waiting almost an hour with the phone outside (sunny day) to see if it detects the satellites.
6. Every app inthe appstore that promise GPS Fixing (reseting, A-GPS and all kind of tests. Funny thing, the sensor IS working acording to those apps.
7. Factory Reset
8. Factory Reset and Erase Cache from the bootmenu. (as indicated in the Asus Forum)
9. Downgraded to Lolipop again. WW-52.20.40.196
10. Again every app to reset the GPS.
Nothing worked.
To my surprise, now I have Lolipop and no GPS. So back to basics but, worst.
The Asus forum told me to Update to the latest version, which I did:
1. Updated my phone with the latest MM version. 4.21.40.223.
2. Put the location options in "High Accuracy" and permissions needed for the apps.
3. As the old software was installed after that, I tried Waze. No GPS Signal was found.
4. Did a factory reset.
5. Put the location options in "High Accuracy" and permissions needed for the apps
6. Installed the apps GPS Toolbox and Waze again, the both can't find a GPS signal. I left the phone outside for 10 minutes.
7. Tried to install the version UL-Z00A-WW-2.20.40.198-user by bootloader, but it says it cannot update to an older version, which sounds about right. (I had to try)
What else can I do? I don't mind going back to Lolipop, but when I did GPS didn't work.
Is there any chance the new Update wrote something apart from software in the chipset that cannot be undone?
Help please, I really need the GPS!
Phone not rooted.
Thanks!
Juan
After long hours of searching, reading and trying I got it fix. How?
0. Have a full charged battery or have your phone plugged to the wall (except for the USB stuff on step number 2, obviously)
0.1. Make backups of all the info in the phone, because everything is going to be erased.
1. Download the version WW-52.20.40.196 from Asus website.(unless you need the other like CN, JK, etc, see Asus site to be sure)
2. Copy it to the internal storage of your phone in the root of it (not in any folder), via USB.
3. Get to the boot loader (Turn off phone and once is off, push the power button with the Up volume one until it vibrates 2 times. Release only the power button until the menu appears) - Search the forum for more details.
4. Select "Recovery Boot" with the volume buttons and press the power button to confirm.
The next steps are all in the Recovery Menu (once it finishes every step it goes back to the original menu, no alerts, sounds or nothing. So check every now and then)
5. Make a Wipe/factory reset, and wait, it takes some time. (use the volume buttons and press the power button to confirm)
6. Make a Wipe of the cache. (use the volume buttons and press the power button to confirm)
7. Install update from Internal storage selecting the name of file you copied on step number 2 (use the volume buttons and press the power button to confirm). It will take a while.
8. Reboot the system (use the volume buttons and press the power button to confirm)
It will restart with the phone in the Lolipop version and the GPS working fine. Even after the Lolipop updates.
Marshmallow update has a bug, that at least with my phone the GPS doesn't work. Tried reinstalling marshmallow latest version after the GPS got fix, just to prove the point, and in fact, it stopped working again.
Then I did all the steps above again and went back to normal again.
I STRONGLY RECOMMEND NOT TO UPDATE TO MARSHMALLOW WITH THE ACTUAL FIRMWARE VERSIONS AVAILABLE.
I also had this problem with Marshmallow ROM, as the GPS is not working in terms of unable to locate any signal from satellites.
However, I also solved the problem with a method sounds very silly.
I turn on my GPS overnight using an application called GPS Status.
The night I turn it on, it was locating 0 satellite (it will write 0/0 SAT). However in the morning, I found that the GPS is now working, locking on 8 out of 24 discovered satellite (it wrote 8/24 SAT).
Now my GPS is working seamlessly.
Thanks! I will try it next weekend. I need my phone this week. Hahaha
I ll post when I do so.
Do you know other similar cases of people who did that and worked?
The thing is, now I have Lollipop again an I noticed how slow the system is running with applications. I d love to have the update, but not sacrificing the GPS
I decided I won't make the test because it doesn't justify the risk and time.
I'll wait for a newer update or just stay with Lollipop.
Just to let you guys know in case someone was waiting for this
I downloaded GPS Status as suggested by SleepingAran and ran it once. Now my Waze is working seamlessly. Thanks!
There's another simple solution that works:
Follow exact steps:
1. Turn on location and set high accuracy mode
2. Open google maps
3. Move your phone several times in the shape of 8 (8-10 times should be enough)
4. Close google maps and clear it from recents screen
5. Start google maps again. Profit

[MTCD/E] [PX5] BT Search and connection issues with device name and pin

Recently some users including me are having issues with BT Connection, device search, setting device name and making changes persistent.
BT MODULES THAT IT WAS TEST ON:
SD-968 - [HA] [MCU MTCE 2.75] Firmware 20180201 and few earlier = WORKS
MD725 - [??] [MCU ???] Oreo Firmware = DO NOT WORK (According to feedback) LogCat needed to see if Firmware communicate with BT Module at all.
METHOD 1 (SHORTER):
1. Force Stop BT app
2. Clear DATA and CACHE for BT app
METHOD 2 (LONGER):
Here are the steps I've done to make it work.
1. Boot device (restart if it was not in deep sleep)
2. Directly go to system BT settings (drop notification and tap on BT)
3. Set Device name and PIN
4. Press refresh
5. Go to Home Screen (Home Button)
6. Open BT App -> Configuration
7. Name and PIN should be entered now
8. Disable/enable Auto Connect and exit app
9. reenter app and configuration to enable Auto connect
10. Make sure that all previous BT profiles for HU are deleted on phone and that phone is visible for all devices (usually when BT configuration is open device is visible)
11. Try to search for devices. It should fail (it failed for me)
12. Go to factory settings
13. Change BT Device even it is wrong one (I have SD-968 I changed to MD725)
14. Tap Apply -> Exit -> CANCEL on reboot prompt (without doing step 13 there will be no scheduled restart)
15. Reenter Factory settings and set correct BT Module (I have SET SD-968) Tap Apply -> Exit -> and Confirm REBOOT
16. After Reboot Go to BT App and try to search for phone it should be found (make sure it is visible like in step 10)
17. If all is OK you should see the phone and you should be able to use it normally (it worked for me)
Attached pictures of some steps for METHOD 2.
NOTE: I'm ATM at HA 6.0.1 Firmware from 20180201 and issue happened after upgrade. Also from what I see Users have same issue with and after Oreo update. Hope I helped
Thanks for the info. Have you tried this method also for oreo rom as well ?
A step that worked for me was to clear data and cache for bluetooth app..

Good point it didn't worked for me but, it can also help. Added to main post.
You can trigger a reboot with "hctreboot" in factory settings. Does that work instead of doing steps 12-15?
I definitely have the BT issue. I have an Xtrons(GS) MTCD/E PX5 Oreo and an Xtrons brand OBDII. They won't talk or disconnect. I'll try this tomorrow morn and report back.

I have same GS MTCE 2.75 PX5 OREO but an old OBD2, give HU same password as OBD2 adapter..

Point of 12-15 is that HU re init Module itself along with software. Not sure if it works that way on MTCD/E but usually it works on modular systems.
Tried with PX5 oreo installed with no luck. Both methods are not working for me.

What???(I thought that this was a trick for oreo)
In my unit BT(MD725) works without any tricks for MM.
I tried your trick with 2 kinds of oreoROM(HA and GS) but BT did not work.
Thanks anyway
I'm sorry, but as I wrote I have SD-968 BT module not MD725. I'll update main thread with so far know to work devices.
Any news?

seems to be the same
The solution is to go back to android 6, the problem is that it is not as fluid in my case as android 8.
Hi, same problem here....
I can not use my ODB2 connector on my Android 8 radio either.
Is there an adapter that works?
Is there a trick to make it work?
Greetings and thank you!!
Hi..any update on how to get the bluetooth working on android 8..

if you still have android 8 installed, try going to factory setting and change the BT Device even it is wrong one (anything other then MD725) tap apply and exit and reboot.
after reboot change the BT device back to the original one (MD725) tap apply and exit and reboot.
after reboot go to the system BT and try to search if the phone name appears let me know.
i still didn't try the above method on android 8, but if anyone with MD725 module is still using android 8 please try and update us.
thanks

Dasaita MMCNP - BT connection problem
Hi, I have Dasaita HA2106-V840-8 a problem with Bluetooth connectivity. First time I managed to connect my phone to Dasaita MMCP (car_kit), but after a few days the devices failed to connect. I guess my device has embedded SD968 BT chip, in accordance with the description.
When I enter the name of the device and new PIN in BT settings, and then turn on finding the device, they are not visible to each other. I tried this other day too, but when I turned MMCP, entered settings was gone (not memorized). No name, no PIN, but also there is no connection. Search doesn't have results. At the end I tried to unpair devices and pair them again, but I get a message on my phone "Unable to communicate with CAR_KIT".
When I entered in settings for BT (settings/car/factory setting/application-choose...) it was set to WQ_BC6. And then I tried to set up SD_BC6, reboot, search BT, nothing was found again. Then I returned to WQ_BC6, reboot, search BT, without success. In the end, I tried to set up SD968, but it's not worth it anyway, MMCP does not see a mobile phone. I also tried several phone models without success. I also went to the BT application and clear data and cache, but always the same thing - BT devices do not see each other. I'm not even sure BT is ON because it doesn't have a special slider to move On/Off.
What should I do? Please help me!
