@IG_Vasilich Yes at some point there was an SD card in the GPS-Card slot. However I removed it after losing the mapdata that was on there through a factory reset. Since then there was no SD Card installed anymore.
Maybe, but I assume that the navi app is still installed and is still looking for its maps on the now missing SD-card.
Thanks for the fast replies from you guys! I really appreciate that!Maybe, but I assume that the navi app is still installed and is still looking for its maps on the now missing SD-card.
Or some persistent property makes the system look for an SD-card, because some program later started (the navi app, maybe no longer installed), might want to access the SD-card. Please try with a cleanly formatted SD-card and see if it runs through the boot process.
I tried it now.I'm afraid you have to flash your unit again, and you have to start with the Joying firmware.
Put the Joying firmware on a fat32 scdard.
Put it in your unit and reset your unit via the pinhole. When the bootlogo appears, reset it immediately. Do this 3 times.
The fourth time it should flash the Joying firmware. When everything is again up and running, you can use the suctom apk to replace the recovery image again and then flash the gtx rom again (if you want to)
If you still have the custom twrp recovery in place, you should try to boot into the twrp recovery. From that point you can reinstall the gtx custom rom (see post #627)Honestly, since I flashed the HU a long time ago, I'm not entirely sure if I replaced the custom recovery with the original one. Since the HU is showing all sorts of unexpected behavior, I'm assuming I did not replace the custom recovery after flashing.
Since you're already mentioning my most likely bad position with the custom recovery still in place:
Do you have any idea about how I could unbrick the HU with the custom recovery still in place?
