No need just make sure that it has USB debugging  to "ON" and connect the PC and device (wait for the USB device and USB debugging on the PC and device to be connected, ensure that all USB drivers are available)   and just run the "**.bat" file and it will do the rest. If you are wiser yu can use this to manually "ROOT"a stock firmware by adding the appropriate file with the appropriate "chmod/chown"  permission statement (I took this from the ROOTING script.)

Sorry bout the late reply been busy on other forums too. If you are living in the US you can request from me  another suitable script specifically for the USA from the rest of the world all you have to do is to change the gps.conf file to your appropriate country.Remember to to rename the file "gps.conf(xyz123)" to just "gps.conf"

After it has finished it will reboot the device.

USE THIS LATEST VERSION

Goto : http://www.arctablet.com/blog/forum/pipo-tablets/improving-the-gps-fix-on-rk3xxx-devices/#p35207

Try this : https://mega.co.nz/#!XlAHXDyC!Qr6y0lhd2rpSAdU0rk-CSmrc36Bjjju4hvFkSEMM_08

or the RK Driver installer for Win7/Win8 (not Win8.1) : http://www.mediafire.com/download/sd9h9dckq10wz09/RK-Release_DriverAssiStant.zip

Or in case of emergency plaese use the universally recommended ADB driver PDA Net (attached below)

Please delete the "build.prop" file inside the folder or just add the sysmbol "##" to the front of "build.prop" file as the build.prop is meant for Max M9Pro with a different version and screen resolution, or else you might end up with a non booting M9 (this build.prop is meant for M9Pro only) Please omit the "build.prop" from being installed into M9 this is meant for M9pro.

Good for you!

You shall be the last support that I will provide on any matter on this Forum. I will NO LONGER ACTIVELY PARTICIPATE on any matter in this Forum except as an observer , (waiting for March '14 when RK factory will release the actual KiTKat kernel not the current 3.026 kernel).

please go to this link for the latest update dont use any previous versions: http://www.arctablet.com/blog/forum/pipo-tablets/improving-the-gps-fix-on-rk3xxx-devices/#p35207

Can I run in for kasty-pipo-m9_pro-442-20140504-rooted7_mu?
Or it needs some modifications?

This is actually a general settings fix for GPS settings , it doesnt solve the problems of poor hardware (like M9Pro it has a metal back cover that hinders a good GPS receptions but every little bit of helps count)

Discard the old files  and use this version only for M9Pro #407 20140504 , since this mod contains the "build.prop" to M9Pro only. (If an advance user you can substitute the buid.prop with your device (any) build.prop) but try to leave evrything else intact for effective settings.

Copy this zip file (DO NOT UNZIP IT) and use CWM to INSTALL. In the NTPSync  app you only need to enter your country code in option "NTP server" example : fr.pool.ntp.org (France.)  de.pool.ntp.org (Germany) you only key in 2 letters and set the settings to update daily.

If you find that a lot of time out to connect to ntp (slow sync with servers)servers to your coutry substitute that with your continent i.e. "europe","asia""north-america", "us"

I give you this download link : https://mega.co.nz/#!LFsxXIRZ!CjO8oT7ustBGlGwBy-pbcCCAbr6ZyrW8yDHi-G7_73E for your request. Unzip only this file get the update.zip file inside. The size is about 70Mb but that is due to me being lazy in writing an elegant script for symlinking busybox so the bloated size is the full "/xbin" folder content. The actual update is less than 25Mb. Sorry about that.

First use Kannan Recovery Flasher (included) to flash TWRPrecovery (incl.). I am an advocate of TWRP Recovery rather than CWM and almost all of my firmware mods have TWRP rather than CWM.

Then install the zip file inside (DO NOT UNZIP !) It will install SuperSU2.49 and correct the original rooting file where the busybox is installed in "/bin" folder whereas majority of root would expect to find "busybox" in the "/xbin" folder (this will correct it.)

It will install GPSTest Pro for testing satellite signal/ NTPSync where it will sync time to your nearest NTPServer (in your case I have set it to Canada/north-america) this is important to sync your device time and satellite time.
