I thought I'd share my phone update nightmare in case it helps anybody. On Dec.13, on my Galaxy A15 5G I was notified of an update to the new One UI version 8. Like I always do with updates, I chose 'update now'. After the update and reboot, the phone got stuck in a boot loop. I would see the Samsung logo along with 'powered by Knox'. Then a message on the bottom left corner, in a microscopic font, something to the effect of 'KERNEL-PANIC'. And then it reboots. In all, about 10 seconds from one reboot to the next. Samsung online chat and a visit to a Samsung certified phone repair center yielded nothing but wasted time. Push and hold the side button for 30 secs would not power off the unit. Volume up or volume down + side button: no reaction. Eventually I figured out how to get into the download mode, by connecting the phone to my PC via USB cable, then press volume up + volume down together. Downloaded ODIN software, found the exact firmware for my phone. Oddly, the first THREE times I flashed the firmware successfully, this did not fix the problem. Still in the boot loop. But by now I was able to get to the recovery mode, to which I chose Factory Reset out of desperation. But still it remained in boot loop. After a FOURTH firmware flash, the phone came to life! I've no idea if I did anything wrong in the repair sequence but there you go. I've since updated the phone to One UI 8 again, this time with no issues.
Thanks for sharing your fix! Itโs really helpful to see how you got the Samsung A15 out of a boot loop that can be so frustrating. Great stepโbyโstep solution that could save others a lot of time!
I have an A 15 Galaxy that was bricked by UI 7. SAMSUNG support gave me an unending list of things to do, which I did, to no avail except to find that I had corrupted software in Play Store & my P services were no longer certified . It went further downhill from there. Support hung up on me when I tried to escalate my situation. Another rep thought she put me on hold but didn't and proceeded to discuss my situation in Portuguese which I translated by Live Caption and promptly got her attention. Now I am finding out I am not the only one. Not sure where to go from here, but I am buying a new phone. I do hold Samsung responsible. This widespread of a problem isn't just an "oops." J. Faith
