Weird restart loop after factory reset
I reset my Tecno Spark 5 Pro (Android 10) because it was getting slow. Ever since then, every time I restart it, it keeps restarting itself like 5 or 6 times before it actually finishes booting. And it randomly powers off later and gets stuck on the Tecno screen forever. I didn’t root it or flash anything weird. Just a normal factory reset. This is driving me crazy. Any idea what could cause this?

If you can’t keep it stable enough for long..try booting it into safe mode and see if it stays running longer there. Sometimes safe mode puts less stress on system resources.
Agree. Priority order should be: recover data first → then fix phone. Don’t jump to firmware flashing until you at least try to extract.
If you care about those videos, stop rebooting repeatedly. Every single boot cycle stresses the storage even more and increases chance of those blocks failing or being overwritten. Try to access internal storage from a PC while it’s still able to stay on for a few minutes. If it doesn’t mount, use a data recovery software on PC and scan it while you still have partial access.
I don’t want to flash and lose everything. I actually have a lot of personal videos still inside that I didn’t move.
Before flashing anything — backup whatever you can. Try turning it on for 15-20 minutes without touching it. Sometimes it settles long enough for a quick data copy. Once you flash a ROM, if anything gets wiped or corrupted further, you can’t easily pull it back.
You might need a full firmware flash with the official Tecno ROM (SP Flash Tool). Factory reset only clears user data. You need something that rewrites the firmware entirely. That’s usually how these are fixed.
This usually happens older budget phones. The memory wears out over time. That Tecno series uses pretty cheap eMMC storage. After 2+ years they start freaking out. When sectors go bad, the OS can’t read certain blocks consistently → half boots → loops.
Yeah that’s what it feels like. I didn’t think a normal reset could break anything though.
Your system partition or boot partition is corrupted. Factory reset doesn’t rewrite it, it just clears data. If the OS layer itself has corruption, this is exactly the behavior..short partial boot cycles : random full freeze at splash logo

And worst case — if none of this stabilizes it long enough, you might need professional help to pull the files before doing firmware reflash. Because once that storage goes, whatever hasn’t been copied becomes unrecoverable permanently.
