Hey @VivekSinghRathore , @TiagoGaetanoTlili , @AbineshAbinesh could you try performing a factory reset of the device after step 1?
You can do this by going to Settings, System, Reset options, Erase all data (factory reset) and then reboot. Then start the OTA process again.

@Rob I got it working, after OTA install I ended in the bootloop but I made factory reset in recovery options and A15 booted just fine on NP2, but it is crashing constantly on mobile data (remotproc 408000 mmc). On WiFi and airplane mode the A15 is really stable, fast and with lower battery consumption compared to A14. But when I tried to turn on data or make call - simply everything with connection to mobile network - the phone crashed again. So for now I am back on A14. Will wait for next build and will try it again.
CYPHER_LYNX same here..

Guys fixed some issues and bring beta 2 for NP2 do not involve Nothing widgets apps need to use stock Android 15 
don’t have much money for Pixel 8 Pro Please make it Stock Android Nothing will grow like millions-billions everyone need stock Android with Snapdragon Performance
Endless restarts with an Android 15 panicky message / all nothing widgets disappearing / all apps using fingerprint useless.
Nothing phone 2 OS 15 update date please tell me
umarfarook_l7AYEhha6t This is a beta only intended for developers, final Android 15 is not expected to drop until at least september and will probably come later for Nothing Phone
Is it possible to hide the Control Center from the lock screen?
Great, A15 is ready to play but I will wait next update to play it since known bugs are quite annoying for me and not the right move to install on my main device.
Since is a major upgrade to Android (A14 - A15), I highly recommend doing the factory reset after installing it.
I’m so excited and looking forward to seeing what the final A15 looks like with NothingOS flavours.
All the best Nothing team! 
Do it work for beta update? I have U2.5-240606-1801-IND
I’m on Nothing OS 2.5.6 on the phone 2a. How can I get the developer preview of Android 15 installed?
Now, the Beta 03 stable version is also available from Google.
NishitShah Follow the instructions at the top of this post ….
hey @everyone when can we expect beta 2 with nothing os integration for phone 2
Anonymous192 it says do not install on 2.5.6 or above
NishitShah I have an NP(1), so I guess we’ll just have to wait …..
We are already in Beta 3 as of today. Program is already updated to load the Beta 3? Facial Recognition and other bugs already fixed?
ToToAntonio Nope.
ToToAntonio This version of Android 15 is only made to test apps as a developer, no fix or further updates are expected.
ToToAntonio Nahh, the fixes/features will come alongside if the DP fixes the bugs and adds new features. Not/yet from Nothing if not mistaken.
*Please don’t compare it with Pixel because you know why.
Unless, like the previous Open Beta, NothingOS 3.0 Open Beta. Then, the fixes, and add/remove features are from Nothing.
So, DP is like a sneak peek or food tester before you enjoy the actual meal. 
Here’s comes Beta 2.
