Boss try mo ngang pumunta sa "Connections > More Connection Settings" check mo if may "Network Unlock" try mong i click kung meron, if wala, siguro software problem yan... di ko lang sure kung by formatting eh maaayos yan o hindi, kung update naman eh, kesa naman sa maghintay ka sa bagong update;
kung may pc ka, try mong mag revert back, sa older update using odin, pero syempre wag mong kakalimutang mag backup...
Walang Network Unlock boss. Ganito kasi nangyari sa phone ko. Pag update ko nang Android 12 after nya pag restart talaga nawala na signal. Nag punta nako sa service center. Pinalitan daw nila nag board under warranty pa nong time na yon. After non nagka signal na. Last week lagi kasi may nagpa pop up na paranv please tap her to complete set up of your devise. Na pindot siguro ng anak ko. Ayon wala na naman signal.
