How To Downgrade Moto G from Android 4.4.2 Kit Kat to Android 4.3 Jelly Bean

How To Downgrade Moto G from Android 4.4.2 Kit Kat to Android 4.3 Jelly Bean

Many people are facing errors while downgrading their Moto G to Android 4.3 after upgrading to Android 4.4 Kit Kat. There are many reasons why you want to downgrade your Moto G to Android 4.3.
Many Indian, Brazilians and other users are facing errors like Automatic Airplane mode, No Signal strenght etc.
I don't kow why Google Lenovo released the Kit Kat update for Moto G without fixing all the bugs. There are many bugs which people are reporting like Signal bar, Airplane mode, less battery backup, can't Enable Battery saver option. Hopefully, I didn't face any such errors, I don't know why people are reporting such errors. Maybe you are the one who is facing bugs after upgrading their Moto G to Android 4.4 Kit Kat. I liked the Android 4.4.2 Kit Kat because of it's sleek UI. Some users said that the UI of Android 4.4 Kit Kat was poor, maybe they don't like it. What I hated was there were too many Google applications starting from Google Play Music to Google News which I don't like!
So when I tried manual method to revert back to Android 4.3 Jelly Bean from 4.4 Kit Kat, I saw an error (bootloader) Preflash validation failed when I typed fastboot.exe flash partition gpt.bin. I was thinking it will be fatal, but then i saw a guide on XDA made by t-bon3 which I think was the best guide for Moto G users to revert back to Android 4.3 JB or to Downgrade to Android 4.3 JB.
The guide clearly states what to do, but some users cannot follow the guide, I don't know why so I am making a clear-cut guide for users to downgrade their Moto Gs to Android 4.3 JB!

Attention!

Also backup your contacts, SMSes, call logs and everything like History, games data etc. by using applications like TitaniumBackup (Pro!) I am not responsible for anything that happens to your device.


YOU DO NOT NEED TO UNLOCK YOUR BOOTLOADER TO DOWNGRAD TO ANDROID 4.3 JELLY BEAN!

  12. I think i should wait for the next update 4.4.3 instead of taking risk of brick my moto g. Yeah, i heard its delayed. But still सब्र का फल मीठा होता ह। letz wait and watch.
