hi everyone ive been having some fun messing with this tablet kinda testing it out for some modding fun i am new at this and im sure i did something wrong and hope you can help. i had rooted the device with kingroot and everything was fine until i tried to use the link2sd then andriod maid pro so after messing with things tring to add more space for the harddrive (yes i wanted to download large games that the 4gigs that came with the tablet wouldnt download due to not enough space) i noticed it kinda lagging so i went and did a factory reset i had done it before and no problems but this time its been over ten hours and and i cant get out of the erasing screen all i see is an andriod with this spinning hexagon looking thing. ive tried hard reset but that wont even go through ive tried many different variations i found people say online along with different types of tablets, so i went into adb to see if i could work from there but after adb devices was entered the tablet didnt appear .... please any help on how to fix this issue . :confused:

thanks

Greenhorn here, what do if you've formatted filesystems and now get please enter pass

I've been playing around with which filesystems I can format the android systems partitions and then install a custom ROM on.

I tried formatting them to F2FS and then installing a CM and Squids kernel found it wouldn't boot, then wiped them back and formatted
them to ext4 (which I think is the default android filesystem) and installed CM and Squid's kernel
and now on boot its asking me to enter a password to boot my android system.

partitions were the filesystems were changed are /system /data /cache.

o_O I really don't want to be admitting this right now that I bjorked my system while tinker gnoming,
and don't know enough to put it back.

But yeah formatting ext4 /data /cache /system and then flashing everything back should have done it right?
