Nexus S won't turn on HELP! i got issues with my Samsung Galaxy Nexus S i9023. It's new mobile. After 2 months i was msg's with my friends,then my phone just restart and its was fine for 1 min. then it turn off. And when i try to turn it on it's showing NEXUS Logo (https://www.youtube.com/watch?v=lWA6WFi3-RM) like in this video. And its can take hours but its will never turn on. I tried to use bootsettings (http://nexusshacks.com/wp-content/uploads/2011/02/nexus-s-root-6.jpg) recovery. But it wont help at all same way. 
Thanks and answer soon.
You need the binary image of recovery and ROM 
Now start in fastboot mode
Flash the recovery
Then flash the ROM 


The recovery and ROM can found on manufacturer's website. However, it is a good idea to try to claim the warranty as it's still 2 months, though I think they will not fix it as you have rooted your device.

Issue the following commands on the terminal:

fastboot devices
fastboot flash recovery recovery.img
fastboot flash system rom.img
fastboot flash reboot
