Alexei Navalny Posted July 4, 2017 Report Share Posted July 4, 2017 TestMode is much safer and easier to use than Hackmode - which installs and modifies your system. Sometimes the install goes awry, leaving your unit unable to boot. To get into TestMode on most X and Z series units, download this file supertestmode.zip to a PC, unzip it, put TestMode.key on a FAT32 formatted SD, and insert it in your unit. IFAIK this file doesn't work on x950 & z150, but if it does, or someone knows one that works - please post to this thread. Quote Link to post Share on other sites
alexchngwt Posted June 25, 2018 Report Share Posted June 25, 2018 Hi there, I recently bought a used car and I had to replace the battery when I was prompted with this password issue. My head unit model is AVH-X8750BT, how do I gain access to the SD card slot as it is behind the touch panel? I do have 2x external USB ports but nothing happened when i inserted the sd card with an adapter. With Regards, Alex Quote Link to post Share on other sites
