I am from India. Similar problem of boot loop after my maiden attempt to root with Dr Ketan's Multitool method for Newbies. Didn't now whether it was rooted so factory reseted the phone to get in the bootloop. No files were seen on int SD. Ext SD seems intact. Had taken an EFS backup from the Ketan's Multitool.
Which firmware should i download?
The Philz screen comes up when I keep Vol Up Home and Power buttons pressed for about 10 secs.
Should i follow Rohit or debenaute?
