[Guide] How to flash/update/reset Nokia Lumia phones using Lumia Software Recovery Tool?

Update (2016) – Lumia Software Recovery Tool (LSRT) described in this older post has now been updated to Windows Device Recovery Tool (WDRT). WDRT supports all old Nokia Lumia phones (WP 7/7.5/7.8/8/8.1) and new Microsoft Lumia devices (WP 8.1 and Windows 10). Despite the name change, WDRT essentially serves the same purpose as LSRT i.e. reset/restore/update a Lumia phone. So please refer to this updated post which describes the use of Windows Device Recovery Tool.

Lumia Software Recovery Tool (LSRT) is an official mobile service software by Microsoft. LSRT has been created to help average Nokia mobile users to solve common firmware related problems at home using their Windows PC. This saves them from the hassle of visiting a service center and also saves money if the mobile is out of warranty. Indirectly it also reduces the workload on authorized service centers (Nokia Care).

With LSRT you can – Reset a Nokia phone to original settings by re-installing phone-software

Update the phone-software to latest available version

Recover a dead/bricked Nokia phone

LSRT can solve most bricked-mobile issues like boot-loop issue (phone is restarting again and again), phone is stuck at Nokia logo/white screen on boot, persistent spinning cog-wheels at boot or during update, BSOD, phone only vibrates on pressing power button and nothing happens then etc. Some common reasons of a bricked-phone are – An interrupted flashing/update process due to computer related issues (power failure, restart, hangs/freeze etc) Connection interruption during flashing/update process Corruption/deletion of system files, virus/malware infection Flashing the phone with an incompatible or corrupt custom firmware

How to use Lumia Software Recovery Tool (LSRT) to flash/update a Nokia phone? Unlike Phoenix and other complicated flashing apps, LSRT is quite simple to use. Lets take a look how it can be used to get your bricked phone back to life (or update it to the latest firmware) –
