Default Gio soft bricked?

I was trying to install custom recovery on GT-s5660M and flashed recovery for GT-s5660. Now its stuck at "Firmware Upgrade Encountered An Issue".

I can still get to download mode. I've tried flashing stock using "One package" and OPS file but it odin gets stuck on 1 part. This is the stock I'm trying to flash: GT-S5660M_MUGKG3_stock_rooted_ROM_v2.7z from here

also tried this stock rom ( but got the same result. the timer keeps running but no progress.

Any help is greatly appreciated
