Hello
I have a chinese 7" MTK GPS device. I want to change boot logo.
Motherboard of this device is: YG-912S-ABFJ-4G
SysInfo:V.912S.711100.130910.4G
I've tried logo.img, logo.bmp, logo.nb0 (800x480 bmp saved as logo.nb0). No success so far.
I've found firmware in the internet, copied it to a 2GB FAT microsd, and whoa! It worked. Whole system was reprogrammed, and it also changed the logo to "MEDIATEK" (it was an asian girl photo before, as the original).
It seems the logo is in logo.nb0 file, but is definately NOT just saved bitmap (cant open it when change to *.bmp, i also tried to save custom logo to logo.nb0m but after programming it shows no logo at all).
Here's link to the firmware
My question is: Howto create a custom logo.nb0 that will work for my device?
alejus (14-03-19)
I downloaded the file 912S firmware.rar from the link you provided and then looked at its contents.
I suggest that you do some more reading about .nb0 files by using a search engine, e.g. , particularly the information at fileinfo.com and file-extensions.org.
The contents of logo.nb0 can be examined with an hex editor such as the free one available at .
There is a reference to a .nb0 file in another post in this section of the forum on p.90 of this (current) thread.
Having got .nb0 files out of the way, the archive contains a file LOGO.bmp, which opens in Windows, as one would expect as it's a bitmap file. It shows the word MEDIATEK to which you refer.
Try finding a bitmap file of a simple nature, which you would like to use for a logo. To start with, make it about the same size as the existing LOGO.bmp.
Replace the current LOGO.bmp file with the one you have created, but save the current file to your computer so that you can use/restore it later if necessary.
Once you have established that your replacement file loads and displays correctly, you can try experimenting with other (larger) files if desired.
If you are unable to find and replace the existing LOGO.bmp file on your GPS unit, replace the MEDIATEK (LOGO.bmp) file in the archive and then reflash the GPS unit.
Please post details of your progress.

It seems that Logo.bmp file doesnt affect the device at all. Its just logo.nb0 that matters. I've changed background of original logo.bmp (MEDIATEK) from black to blue, saved it (got same file size!) and flashed it. Guess what- device booted up with original mediatek logo, not my custom one
Hex editor shows diffrences between files logo.bmp and logo.nb0 (for "MEDIATEK" logo). Headers of the files are different. Only the "BM8" seems to be same, it looks like determined type of bmp image.

BM8¸......6...(... ...ŕ............¸............
Theres also 375KB more data in *.nb0 file, it's too much to determine. I've tried to add header from logo.nb0 to by custom *.bmp file, then saved it as logo.nb0 and flashed it- doesnt work so far.11 EF CD AB 06 00 00 00 20 03 E0 01 00 B8 0B 00 00 00 00 00 00 00 00 00 E8 03 00 00 5A 00 00 00 C0 03 00 00 B8 0B 00 00 00 00 02 00 20 00 FF 01 20 00 FF 01 0C 02 00 00 2F 00 4C 00 6B 03 4C 00 6B 03 9F 03 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 42 4D 38 94 11 00 00 00 00 00 36 00 00 00 28 00 00 00 20 03 00 00 E0 01 00 00 01 00 18 00 00 00 00 00 02 94 11 00 12 0B 00 00 12 0B 00 00 00 00 00 00 00 00 00 00 00 00

The information posted at might help you.
I have the same OS on my satnav unit. Also trying to figure out how to flash it etc. The OS is definitely Windows CE, i think its version 6.0. The manufacturer is Iokone i think.. Best way to find out more details is search on with the vehicle type etc.
I just heard back from the suppliers of my unit and they claim that the software is no longer available as production has been stopped in 2016 and all files deleted... Couldn't get anything out of them!
Hi Guys,
I'm trying to figure out how to flash my car navigation system. I would really appreciate any help. The manufacturers are more than useless and supposedly can not supply any information or software as the system is no longer in production....
All works fine except for the GPS (fails to find the navigation path).
So I was thinking is it possible to reinstall wince 6.0 or Android? If so what version can I use on this device. Details are in the pictures attached.
Many thanks!
After few years of using, XDrive won't to launch any more his default launcher.
This GPS software always used navigation software from SD card and never from his flash drive.
Regardless is the SD card in slot or not I always get this screen:
I tried every posible combination, to hold long time the power buttion till I starting it witn/without USB, restart buttion, but nothing. Alwayas the same.
The device didn't felt down or it have not mechanical damage. He felt in this software state from hismself.
When I connect him to USB of PC I got this info:
The picture I expecting on device would looks like this:
I tried to copy different tools for repairing and booting directly to WINCE on SD card but without success.
Can someone suggest me what to do?
Where can I found the original FW for him?
Thx.
Does anyone have a firmware that can be used on this unit?
Thank you !
What's wrong with the firmware currently in it?

Hi, I have an Orange G430M gps system, it works almost fine since 2016, but I always felt that I could do more with this device.
When I was researching for better bluetooth connections/apps I realised that its windows CE 6.0 does not have all of its features and have found that it could be the cause for it do not connect to my phone or to my new bluetooth helmet intercom.
Could someone here help me to update my winCE6.0 to a full WinCE6.0 keeping all apps that I already have? Or, if more simple, help me to find a fix to my bluetooth?
