Qhov ua tsis tau zoo ntawm qhov chaw uas daim npav tau teeb tsa yog qhov muaj ntauxwm txheej. Nrog nws, lub xov tooj tsis pom SIM daim npav. Qhov no kuj tshwm sim thaum cov lej feem ntau hloov pauv, yog tias lub qhov rooj lossis lub cuab yeej nws tus kheej puas lawm. Yuav tsum kuaj xyuas thiab hloov qhov chaw ntawm qhov chaw pabcuam.
Lub xov tooj tsis pom SIM daim npav txawm tias lub operating system lossis software (software) ntawm lub cuab yeej ua haujlwm tsis zoo. Qhov no tshwm sim nrog qhov tsis raug flashing, nrog rau qhov tsis raug reinstallation. Yuav ua li cas kho qhov teeb meem no? Ua ib qho reinstall, koj tseem tuaj yeem rov qab tau cov thaub qab.
