[Galaxy Note 3 Q&A, Help & Troubleshooting] drheart:
TALE OF A HEART BROKEN ROOT ATTEMPT​

hello xda members

i am a note 3 N900 (exynos)user from India. i bought this phone in december 2013. all was going pretty good for a while. after almost 6 months the battery life started to diminish. initially i could get 24 h total time with 3-4 hours screen time and with 3G data on intermittently. but once the battery life decreased and got heating issues near the camera i decided to root. I had taken my phone to authorized samsung service centres twice to know whether my phone has any battery issues to which they said " everything is fine ". i waited till the end of my warranty period and attempted to root in january 2015. i have been doing many researches by reading posts and watching videos online. Finally the D day came and i decided to go for it !! I tried everything as mentioned in the video by cursed4eva based on chainfires post. everything went fine and finally got a message : FAILED !! i tried once more and the end result was same. then on my 46k worth note 3 i saw this heart breaking message " "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.". i tried to do so in kies but it was also futile. finally i took my phone to a nearby mobile shop and they said this can be repaired but will take some time, pls come in the afternoon. I was totally disappointed and was thinking just because of this root attempt i have spoiled all these hard earned money of mine :( At around 5 pm in the evening i got the phone back . i was so happy to see it was working fine ! but i lost 500 indian rupees for that !

End result of that tiring day was like this : i tripped my knox counter, phone wasnt rooted and lost 500 rupees

later my battery life decreased. after a full charge now i get only 14 hrs with 2.5-3 h screen time( phone is just 1 year old). when i tried to search for any soft ware updates i got one more wonderful message which conveyed the message" your device has been modified and no OTA " When i hear that lollipop update is at the door steps i can only sit back with a heart full of sorrow :( :( :(:(

dear friends out here , i need your priceless help in this issue. I am not well versed with this rooting stuff , so need a simple explanation about what actually would have gone wrong with my rooting extravaganza !! i have read some posts that my mobile can be modified in such a way that knox counter will be 0x0 and system status original which will help me update via OTA. so please guide me through what all things have to be done and what to do in case i see the heart breaker "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." again !!! . After all these , i tried to format my phone thinking it will improve the battery life, but factory resetting both ways is impossible now.

in concise , my requirements

1. need to root my device safely- Warranty period is over now
