Inabidi uinstall hii kitu https://support.microsoft.com/en-us/help/12379/windows-10-mobile-device-recovery-tool-faq (Nadhani ndio uliyoinstall) Kisha hakikisha una bundle ya kutosha na mtandao wenye spidi itadownload operating system nzima ambayo ni GB au zaidi.

Jaribu kutochomeka simu kisha click My Device not found kisha fuata maelekezo.

Jaribu kuuinstall hiyo software futa image iliyokuwa dowloaded kisha insatll upya.

Jaribu machine nyingine ikikataa.
