my TCL P8M updated from Android 9 to 11, since then i noticed a big performance drop.
Not likely but maybe a factory reset would help.
Check xda.
Hard reset tv may fix problem
thank you guys for all your comments, much appreciated. i'll check with XDA and i'll let you know.
i checked XDA and find out that downgrade is possible and worked for many users with similar problems. here's what a did but with no succes:
so i tried to downgrade from v715 to v616 but unsuccessfully
1- i put img file for v616 in usb (exfat32) then plug of my tv
2- unsert the usb and hod the power button for 5s
but it displayed (no command) instead of starting the downgrade process.
could someone please give me an assistance.
Hi, i have e TCL P715 device and it's in a position that's hard for me to see It. Could someone please post a photo of the location of the phisical power button for this model?
Get a Nvidia shield of will have way better performance than a TV with built in Android
Maybe. You would have to find a copy of the firmware and then know how to get the device to boot that. I expect you might want to check out xda-developers.com and see if anyone has already gathered the files and instructions.
