The reset gesture Jackery tells you to use - it changes by model
Steps and confirmation signals below are quoted from Jackery's own help-centre articles for error codes F0-F9.
1
Hold POWER + USB together for 5 seconds
MOST EXPLORER MODELS
Screen briefly goes dark, then relights showing the battery percentage and status. That relight is the confirmation.
This is the reset Jackery lists for F0, F1, F2, F3, F4, F5, F6, F8 and F9.
2
Hold DISPLAY + USB together for 10 seconds
PRO SERIES UNITS
The display briefly shows 8888, then returns to the normal interface. Jackery names this gesture explicitly
for "Pro series" in the F6 and F7 articles.
3
Light the screen, tap DISPLAY 6 times, then press and hold
SPECIFIC FIRMWARE (QUOTED IN ONE F0 ARTICLE)
Success is confirmed when the screen shows 021 011. Only appears in one of Jackery's F0 articles, so treat
it as a fallback gesture if neither of the first two does anything.
After any reset, Jackery's F0, F3 and F5 articles add the same follow-up: charge for at least 30 minutes on a
standard household socket, then re-check whether the unit behaves normally.
