Since May 2025, Googles approach on Play Integrity has changed requiring a valid attestation key signed by Google to pass DEVICE or STRONG integrity.

However Play Integrity has NOTHING TO DO WITH THE ROMS.

Please respect your devices ROM maintainers and STOP ASKING THEM FOR PLAY INTEGRITY BYPASS TIPS. This is off their hands and they cannot help you + youre turning annoying.

Instead ask on Telegrams which specialize on Play Integrity.

Telegram version work in progress

Information for newer Samsung devices

Considering the Galaxy A70 is aging and people are moving or have moved to a new Samsung, the company is slowly pushing Android 16 updates with a higher Bootloader version, meaning you CANNOT downgrade to Android 15.

As it is known Samsung prevents the bootloader from being unlocked since Android 16 and the cause of their decision is unknown(It is speculated that the recent firmware leak incidents they had made them take such a decision).

If you have done the fatal mistake of updating to Android 16 and still want to do custom roms or rooting to your device you have unfortunately SEALED its fate.

DO NOT bother anybody about wanting to unlock your device while being recommended by your developers to stay for now on Android 15.

If you are still into an upgrade path it is recommended to head to devices like the Google Pixel that still as of now provide easy Bootloader unlockability.

(LegacyUI Nightly) Galaxy A36 Firmware Port for the Galaxy A70

Case you ask. You can dirty flash on top of old UN1CA-A70 builds

I'm looking for active people who might be interested to test LegacyUI internal builds. You need to basically be active and have experience on getting things like logcats. If you believe you fit the criteria, ping me at @tsn7870(Do not dm else ill reject you instantly). Ill only pick 5 people as of now. If you are from Europe, mention that too for timezone reasons.
