After flashing the wrong rom, the tablet stopped booting. It was 2 years ago when I first installed the ROM. I probably chose the F version (for the Tab 2 A7-30F model) and did not uncheck any block. Now it doesn't respond to anything. When connected to a laptop it is detected as MediaTek PreLoader USB VCOM (Android) (COM9) and it keeps appearing and disappearing. I charged it all day until the power consumption dropped, but it didn't help. Today I tried to fix it with the Test Point method, but unfortunately it didn't help either. I have tried many times to flash it in many different ways. The tablet is already 8 years old. For now, I have it open and with the charged battery removed. I'm open to repair suggestions. I really hope we can fix it together. Thank you

Po sflashowaniu niewłaściwego romu tablet przestał się uruchamiać. To było 2 lata temu, kiedy po raz pierwszy zainstalowałem ROM. Wybrałem chyba wersję F (dla modelu Tab 2 A7-30F) i nie odznaczyłem żadnego bloku. Teraz nie reaguje na nic. Po podłączeniu do laptopa jest wykrywany jako MediaTek PreLoader USB VCOM (Android) (COM9) i ciągle się pojawia i znika. Ładowałem go cały dzień, aż pobór prądu spadł, ale to nie pomogło. Dzisiaj próbowałem to naprawić metodą Test Point, ale niestety też nie pomogło. Wiele razy próbowałem sflashować go na wiele różnych sposobów. Tablet ma już 8 lat. Obecnie mam go otwartego iz wyjętą naładowaną baterią. Jestem otwarty na propozycje naprawy. Naprawdę mam nadzieję, że wspólnie to naprawimy. Dziękuję

Do you have the correct firmware?
