Opened it up and wah it was a mess. All the dried up battery water was inside and it was slimy. Took it for a wash and rubbed it clean. At first i thought it would be a simple thing cause maybe it was just dirt but after washing and trying to turn it on again, it didn't seem so easy.
Spent like 30 mins before I figured out that the battery water has actually corroded the conducting tracks on the PCB to the extent that a few of them are no longer conducting anymore. So i whipped out my trusty soldering iron and some enamel coated wire and began re-routing the tracks with the enamel wire. It wasn't easy and my hands were kind of shaky today.
After around 30 mins, i finally finished re-routing all the necessary tracks. Tried it again but oh bugger, it was even worst. I tried and tried and tried all sorts of method but it just didn't work. Logic was telling me that what i did was correct but i just couldn't solve the problem. I got so frustrated that i decided to give up.
I closed up the thing and screwed the whole thing up till the final cover. It was only then that i realised that i had screwed the screw in the wrong place inside so i couldn't screw the top cover up. Screw it!
So i had to reopen the whole thing again. This made me hand itchy again and i decided to give it one last shot. I desoldered the whole thing, and resoldered the whole thing again but this time in phases so that i would know which track that i re-routed controlled which buttons. This was a better choice as i could see if the soldering was done right. The first one went in and :D It worked! I restored the number zero and some other numbers when replacing one track. Then i moved on to the rest and finally everything was back and working fine.
I tried to neaten my soldering with some solder flux and dang, that was a bad decision. it screwed the whole thing again-_- Now the stupid feeling was feeling up in me and i was starting to feel damn sian about this. At first i didn't know what was wrong again but heck, i decided to just wash it with some water again. WOW! After washing with water and drying it with a hair dryer, it worked again! So happy. And i realised that this thing couldn't had alot of flux lying on the conducting pads cause i think the flux could conduct electricity too. So yea washing away the flux solved the problem. Closed it up and :D a job done again. So happy!
Yea okay i guess about 90% of the people who read what was up there understood nuts about it but in short i repaired another GC.
So anw, yesterday's night was very very clear. I couldn't resist but to take a photo of it. Here it is:

Peering through the clear night sky, I couldn't resist myself but to feel helpless...
