Do not boot recovery on reboot screen it make you phone stuck in recovery and thanks school computer install one ui core

Hello Samsung Galaxy A02 fellas...here just little bit reminder for the people want to downgrade their Android version from Android 11 to Android 10 or other firmware version.As we know, Samsung update their bootloader regularly from monthly update (Security Patch) or we call it as Binary. If you want to downgrade make sure the binary is same (You can check it on Samfrw website). My suggestion is if you thinking to downgrade your device in future, stop updating your device to latest firmware. If you already updated your device to latest firmware, just keep praying for Samsung didn't update the bootloader/binary.

Hi,I have experience a camera bug on some gsi "flashlight bug" (only on camera) maybe you are experience it or not but if you are experience it just use a gcam go in notes.

How to fix mobile data not working in gsi? (This method I found by my self,so if you have another just follow it)


First go to setting/Network and Internet/Mobile network/preferred network type/Choose LTE/4G

Notes the setting will be force close just ignore it.


If it still not work check the APN setting

A02 has update to U3 so if you update your devices to u3 you will not able to downgrade to other binary

And also if you are in U2 you can't downgrade to U1 (which is a early firmware for this phone)

If you are want to update just update it but you can't downgrade it to a lower version :)
