Symptoms
- Tablet shows the manufacturer logo, then restarts, repeating the cycle
- Never reaches the lock screen or home screen
- Started after an update or a crash
Likely causes
- CommonFailed or interrupted software updateAn update that didn't complete properly can leave the system unable to fully boot.
- CommonCorrupted system cache or dataCache corruption can prevent normal startup even though the core system is intact.
- PossibleStorage nearly full, preventing the OS from completing startup tasksSome systems need free space to finish boot-time processes.
What to do
- Let it attempt to boot fully for at least 10–15 minutes in case it's a one-time slow update process.
- Force restart using your tablet's specific button combination.
- If it keeps looping, look up your tablet model's recovery mode steps (usually a different button combination held during power-on).
- In recovery mode, try 'restart' or 'clear cache' options before attempting a factory reset, since a factory reset erases data.
- If you must factory reset and have no recent backup, consider professional data recovery first if the data is important.
- If recovery mode itself won't load, this points to a deeper hardware or firmware issue needing a professional.
When to call a pro
If recovery mode doesn't load or a cache clear/reset doesn't fix the loop, a repair shop or the manufacturer can attempt a deeper firmware reflash.
