[AC Question]

Hi,

I changed my Nexus 4 runtime to ART from DELVAK and after that I am unable to boot it it keeps on showing boot screen. I waited for 4 hours for it to book but it is still stuck. Switched off and tried again but no help

Please help me.

Thanks,
Piyush

Welcome to Android Central! Are you rooted or unrooted? If you're unrooted, or rooted and running the stock ROM, try booting into Recovery and clearing the system cache partition: Reset: Google Nexus 4 | T-Mobile Support

I am unrooted running stock ROM. I tried clearing the system cache partition but still it doesnt boot up and stuck at boot animation. Looks like factory reset is only option. Is there someway I can change it to DELVAK from ART without booting? I dont want to lose some of the data on phone if possible.

Thanks for your quick help!

I don't know of any way to do it at that stage, sorry.
