I have the Korean Model SHW-M480W Galaxy Note 10.1 which is a wifi model just like the international wifi model GT-N8103. They are identical in terms of hardware, so I thought I could flash any custom ROM that's made for the GT-N8013. Turns out I was wrong. I have flashed OmniROM, Bliss Stalk ROM, CarbonROM, and even Hyperdrive ROM which is based on Touchwiz and not AOSP. All of them flashed normally, but then the device got stuck on the boot screen every single time. I have tried clearing data, cache, dalvik cache but nothing has worked. Why does this happen if they both have the exact same hardware? I hate to be stuck with this ugly and painfully slow kitkat Touchwiz forever.
