Hey, Recently In Big Sur I mount the EFI partition and DELETED the embedded OS folder just to check the HORROR back again. I was stuck at “Critical Software Update Needed You cant use this……..bla bla” After deleting EFI partition I knew I had to re-install the OS which will rebuild the EFI but some how after Few tries with downloading the critical update I booted in to “ Option+Command+R” combo and for some reason It booted straight in to My Login Screen. Anyone ELSE can try this?

How to repair the Antena cable connected with Long Cable beside the battery. My repair man somehow managed to dislocate that and then solder that. Now 4g reception is very bad? Inside home no reception and when I'm outside it is okay? also takes a lot of time to chaange from one network to other!

mine is also a T-mobile usingg in Bangladesh. Initially it was okay! But now not usable due to network condition.
