no idea, google yourself
I didn't face that issue before
cf auto root is the best
and what ROM you using ?
framaroot not working on stock 4.3
don't downgrade, else your IMEI number got problem
downgrade back to v2 firmware better
can root as well
look carefully

what are you using currently?

i did not recomend my friends looking for nexus 5.

because the battery life is not good. (at least its not an all day phone)
especially those note 2 users sure cannot accept the sudden drop in battery life

my relative wana give me s4, it sounds tempting, but i reject it in the end.
after much consideration, those extra feature not worth the drop in battery life.
currently my s3 with 3000mAh battery can last me all day, morning till night with heavy usage.

i dont want to go back to a time where i MUST charge my phone in the evening,
or always worry about battery life.
i always wanted to go for a nexus phone. my biggest complain last time is camera and storage.
nexus 5 fix this with good camera and have 32gb.
but now i have new craving, i wan all day battery life phone also.
