Okay so I fixed my PS3. I formatted my HDD and tried install 3.55 Kmeaw, but it failed at 10% saying the same error, 8002F14E.
So I kept restarting it until the count down timer was gone and a guide was shown on the screen; hold down the power button until the system beeps and unplug it from the back then restart it a few minutes later. I did that, but I left my PS3 off for more than 12 hours.
After 12 hours had gone by I restarted my PS3 and the update worked. Now I have 3.55 Kmeaw.
Now the real question is how do I upgrade to 3.55.2 Rebug without getting that stupid error again?
