Jule try with apple and webinstaller via USB-A. Again with xubuntu (Ubuntu 22.04.5 LTS ; Kernel 6.8.0-87) via USB-C. Same! Hash ok, no error during flash. What can I do now?
Novalissoide Jule is it the same P7a as back in your earlier thread? https://discuss.grapheneos.org/d/22359-screen-frozen-after-install
Novalissoide Jule If the symtoms stays the same after a valid reinstall, I believe it is faulty hardware. Try remove any physical Sim-card, and reboot just in case it might be faulty.
