Error installing Android 4.3 using adb sideload ON Nexus4

[kaustubhpatil]

Situation : My 2 months old LG Nexus 4 battery drained out completely one day and even after charging it fully the phone is still stuck in boot-loop with Nexus 'X' logo.

What I did :
- Tried factory reset from recovery mode multiple times but no luck.
- I tried to install factory 4.3 as well as 4.2.2 using adb sideload but constantly get the error.. "Signature verification failed". I checked the md5 checksum for my downloaded file and it seems fine.

What am I doing wrong here ? Amongst the images downloaded in a .tgz file what is the the file I should be using for sideload ? Everywhere i searched for help its mentioned that the zip file for the image should be renamed to update.zip. Is this necessary ? also the factory images are in .tgz format not .zip

What am I missing here ? Sorry but I am a novice with Android so excuse me if this question is sort of basic.

Note : I am using xubuntu to run the adb command

Would be grateful for any help.. been stuck in this situation for last 5 days ...

you have to extract the .tgz file and use fastboot instead of adb. open file flash-all.sh to get all the fastboot command
adb sideload is for update and not for factory image load
