How do I fix a tablet that accepts the passcode then returns to the lock screen?
Answer
Charge the tablet for at least 30 minutes first, then retry the passcode. If it still loops with no error code, restart the tablet and confirm you are using the correct lock type; avoid factory reset until simpler power and restart steps fail.
Before you start: stop right away if…
- A factory reset will erase apps and local data and should be a last resort.
- Do not install unofficial “unlock” apps or share your passcode with unexpected remote helpers.
Follow these steps
Charge before more attempts
Plug the tablet into a known-good charger and cable. Leave it charging for at least 30 minutes, even if the screen still shows the lock screen.
You should see: The charging indicator appears or the battery level rises enough for a stable unlock attempt.
Retry the passcode after charging
Enter the passcode carefully again. Watch for any brief error, wrong-PIN message, or keyboard glitch.
You should see: Either the home screen opens, or you confirm it still loops with no useful error text.
Force a full restart
Hold the power button (and volume down if your CP10 requires it) until the tablet restarts. Wait for the lock screen to return fully before unlocking again.
You should see: The tablet reboots cleanly and gives one fresh unlock attempt.
Confirm lock type and next options
If the loop continues, note whether you use PIN, pattern, or password. Prefer official manufacturer or Google account recovery paths for that tablet only after charging and restart fail; avoid unknown unlock apps.
You should see: You know whether to continue with official account recovery or seek in-person support without risky third-party tools.

Extra tips
What to look for: Passcode appears accepted then the same lock screen returns, whether any error message or code appears, and the battery/charging indicator on a CP10 or similar Android tablet.
Before you change anything: Connect a working charger and cable before trying resets. Write down whether any error text appears—even briefly. Do not factory reset until you accept that local data may be erased. Never share your passcode with unexpected callers offering remote unlock help.
