Back to noot v9 great? because s3 is my only phone haha, not playing games with phone , just expecting something smooth and lag free ~

Yeah it's ok nice rom - I have installed many roms but my son still prefer this rom.
You may try other rom first such as Euphoria , Qaraqumus and NCSRom
These roms are quite good.

hahahha....
just having car accident recently... later got money from socso... itchy to get new phone.. LoL

Sorry to hear that - for budget phone can go for Lenovo K3 Note or look for used Note 3 - I just installed Norma rom S6 v5 for my wife's Note3 and her sister - not bad ooo - almost as fast as Note4 on Sweet Rom.

Bro I got an issue here...which I can't get the solution from google..
No matter what ROM I flashed ...my audio/mic is not working when receiving or making phone call unless I turn on the loudspeaker mode...anyone facing this problem before?

I did factory reset , wipe both caches and even wipe to install a new ROM ( using philz touch ) but the result is the same..Stock ROM no problem =\

Try do these steps on the latest TWRP (others recovery i never tried)
1.Go to recovery - Wipe - Advance Wipe - choose Dalvil cache|system|data|cache (only these 4 elements - internal storage & micro SDcard DON'T TOUCH) - Do these steps for 3 times.
2.Go to Wipe - Slide the arrow to auto wipe & auto factory reset.
3.Install the rom after clean wipe (as per the above)
4.Wipe Dalvik cache
5.Reboot system.

bro.. need help..lately my s3.. easy over heat and power drain very fast?

is this sign of motherboard failure soon or got virus?

tq

Check wakelock first. There should be something preventing your phone from sleep.

My S3 has been acting very weird lately, sometimes it restarts itself and everything back to the basic, which means all the apps i downloaded were erased and the data on the internal memory. I have been performing hardware reset countless times, the problem still persists. Any idea what is wrong with my phone? Or has it come to the end of its journey to serve me? T^T

What's the last thing u did on your phone?

Just normal usage, the last software i installed was Ramen game, it was a few weeks back then. One morning i woke up to my phone showing touchwiz not responding. So i did a factory reset to that. Then my messengers were acting strange after i installed everything, not responding. So i did a hard reset.

Since then my phone occasionally reset itself. I have no idea what is wrong with it.

Custom rom is the answer for this random reboots.

Sounds like a problem with partition. Try repartition your phone.

I guess i have to figure how to root my phone. T^T

Thank you for the suggestion, I will try to search it up on how it works.

It's very easy - plenty in YouTube

Dear sifu, currently I'm using Temasek CM12.1 ROM. I want to go back to stock rom using Odin. Tired of non-stable rom.

Question:
- Will I get that infamous efs corrupt/imei null when I flash back stock rom? I don't even remember either my efs is v1 or v2.
- Other than official stock rom, is there any stock based rom (stable) that sifu recommended?

Thank you so much!

Just flashback to latest S3/stock rom you are good to go without worrying about the efs and if you do you can backup using SamsungTools in xda.
You can try also back to n00t v9 rom or check my previous post back for direct link.

Awesome! Will flash back latest stock rom tonight. Thank you so much!

Do I have to root the phone before installing a custom rom? how do i tell which version of Odin should I download?
