Sorry but I switched the order I tried flashing. I tried Android 9 first and then 10. I guess this is not a good way to introduce myself to the form, by being sloppy.While I have used custom ROMs before I am really very inexperienced at this.
I have a T350 that I rooted and installed TWRP_3.5.0_9_SM-T350_Unofficial that I got from this forum.
I then tried to flash crDroidAndroid-10.0-20210411-gt58wifi-v6.16.zip. When I rebooted after TWRP finished the crDroid logo came up and never went away. I let it run overnight just to see what might happen.
I was able to get back into TWRP (first had to go to download mode) and then tried to flash crDroidAndroid-9.0-20200125-gt58wifi-v5.11.zip. I have the same issue albeit the logo was now in color.
Since I can get to download mode with a bit of playing I can reflash the stock 7.1.1 and go through rooting again, but I'd rather not if possible.
Does anyone have some suggestions that I could try before I go back to stock?
