Welcome to Android Central! Did you update it officially with an over-the-air update? Or did you flash it manually? If the latter, are you sure you used the correct firmware?

Try booting into Safe Mode: https://support.google.com/nexus/answer/2852139?hl=en

hello, thanks for the fast reply, it was updated OTA, it was ok at first, then after a couple of days usage, it began freezing, apps hanging, i looked for answers over the net, and i found out that wiping the cache may help, so i did, it runs fine for another day or two, but it just lags so much that its barely usable, so i decided to factory reset it, i have nothing important on the tablet (all the apps installed are free anyway) that when it all started. it stops at " formating /data... everything fails, cant even go to bootloader, it shows android with a red exclamation point... pls help, im not a techie but i can learn fast, thanks a million

Boy, that doesn't look good. Try reflashing the factory image: How to manually update your Nexus | Android Central. Find the proper firmware here: https://developers.google.com/android/nexus/images

the link you gave me is not possible because i cannot access the bootloader anymore, thanks anyway but i think my tablet is toast will now have to get a new one (it's my daughter's tablet) but will still look for solutions if there 's a chance to fix this, thanks thanks
