Welcome to Drovidia. In this article, I will share a tutorial on how to flash the Samsung Galaxy A15 with model SM-A155F that is experiencing system problems such as bootloop (stuck on logo), errors, or failed flashing.
I have tried this method of reinstalling the Samsung Galaxy A15 OS, and it successfully fixed the bootloop stuck on logo, and also successfully downgraded or upgraded the OS version.
So how do you fix a Samsung Galaxy A15 bootloop stuck on logo or simply downgrade or update the OS by reinstalling the firmware? Read this article to the end,d and please don't be lazy about reading so that you don't misunderstand and don't cause the flashing process to fail.
Here are the firmware version details for SM-A155F/SD that I used.d, I have compressed it so that its size is much smaller than the original size without changing/damaging the Samsung Galaxy A15 firmware files that you can download:
- AP Version: A155FXXS9DZA2
- CSC Version: A155FOLE9DZA2
- Android Version: B(Android 16)
- Binary: 9
- Security Patch Level: 2026-01-01
- Download via Google Drive password: evilicacelldotcom
Actually, it doesn't have to be exactly the same. However, if the firmware and phone model are already the same, then the flashing process is very likely to succeed. But if it has already completely died and you don't know the exact version details, you can just give it a try, and there's no harm in doing so either. I have also tried it, and it succeeded 100% without any problems.
