I update my s3 to android 4.1.1 yesterday. Then I saw a leaked rom android 4.1.2 in sammobile today. I installed it and found out that it has a lot of bugs. I tried to install android 4.1.1 back and after install, my phone cannot boot. What should I do?
One more thing, I can stall android 4.1.2 (the leaked rom) and can reboot. But I cannot reboot after I install android 4.1.1 rom.
try a factory reset

Do a complete wipe (factore reset, dalvik, cache) and install the correct rom version. Also make sure you're running the latest CWM Recovery.
Hello to all, this is my first post and thread, I hope everyone is ok.
Well just yesterday I updated my samsung s3 to a kitkat 4.4, it is a custom version and I do not like it and decided to downgrade it to a 4.1.2, but I have tried several times and I cannot do it
I have used, odin 3.07 and 3.09, lastest version of twrp and cwm recovery and nothing, the twrp log file is attached.
I will appreciate some help, I can only install the 4.4 kitkat but I want to go back to any version, I have 4.1.2, 4.2.2 and 4.3 and none of them work.

I have Samsung S3 GT-I9300CDMA /GSM mobile global unlocked mobile.I am using CDMA network in India. I want to install CM 11 or 12 on mine mobile but I think it’s not possible as bootloader is locked. The snap shot of the android firmware version is attached .I have rooted it with towel root app but unable to unlock bootloader as its android version4.4.2.I tried to install TWRP recovery but its failed.
It seems that Verizon SGH-I535 4.4.2 stock ROM Is installed on Samsung S3 GT-I9300 mobile.
I want to install safe strap on mobile,before that I want to download 4.4.2 stock ROM which is installed on my mobile.Pls suggest
1)Which firmware I have to flash in case its get bricked? Verizon I535- 4.4.2 stock ROM or Samsung S3 GT-i9300,Base band version I9300XXUGNA8,Build number KOT49H.I9300XXUGND5 ?
I am unable to find out the firmware installed on my mobile on google.
2) Can anyone provide me the link from which I can download this firmware.
if im not wrong i never found stock kitkat rom for the s3 i9300 samsung never released one , god knows why , but i can tell you if you really wanna try a build then i'd suggest you try cm 11 one of the snapshot versions it worked great for me and it made my device so much better.
Bootloader of my mobile is locked so i cant flash CM11. I want to flash ROM using Safestrap. I required the 4.4.2 version of Stock ROM which is installed on my mobile, in case my mobile get Bricked.
I have an official lollipop upgrade rom downloaded and installed on my huafung-bungding-giggling mobile and it works great
I have now found an official marshmallow upgrade but it says
"there’s no official rollback available right now, so you’ll have to stay on Marshmallow for a while."
If I install it and I don't like it then can I not just reinstall the lollipop image?
Please be clear with your words,
Now what ROM you are using and also let me know with andriod ver.???
Originally running Android 4.4
Recently found Android 5.1 rom official upgrade
installed and working peachy
Now I have found the official Android 6.0 rom online update for my phone
My question is if I install the marshmallow rom and I don't like it. If I have the lollipop rom what is to stop me installing it back?
I'd there something that I'm not getting, that would prevent me rolling back?
Actually I'll just go for it
