Thank you for reaching out. We would recommend a software reflash. We have a couple of options available:
1.UbreakIfix- walk-in service center
2. Smart Switch for PC.
Please let me know how you would like to proceed and we would be happy to assist you with further troubleshooting steps.
I'm not aware of any walk in service centers in my area, so if you'd help with any step by steps on how to reflash I'd appreciate it. I would also like to ask if there's any chance I'd lose internal files/memory such as pics/videos? I haven't backed them up yet.
Thank you for following up. Give this step a try first: Press and hold the power button and the volume down keep together until the phone does a soft reset which would act as if the battery was removed from your device. Yes, in order to do the software reflash on your device it would require a factory reset which would delete all the of saved information in your phone that hasn't been backed up.
Just wanted to check in and see if the reset steps sent to you privately helped with your frozen screen issue?
No, no it didn't, still bricked. Soft reset again and everything, with and without simcard, no private messages about anything yet. If I have to reflash, I would really appreciate help. Help of any kind actually, please.
