Thanks for contacting us and really sorry for inconvenience caused.
Would you please share more information about the usage scenario when you were using the phone and then boot loop appeared?
What apps were you using at that moment and what about the current software?
For boot loop, there is a self-help solution, would you like to try this official SD ROM recovery?
First check the CU reference on the battery label, and then download the related SD rom and follow the guidance step by step.
REMEMBER to remove SD card first, thanks.If you have any further question, please feel free to contact us. Thanks.
If it doesn't work, you could contact our service center technicians. Make a phone call first, maybe you could ship your phone to service center and then you don't need to pay a visit to service center.
