A few weeks ago my friends Honor 7 display cracked. So I ordered a new display+frame from "Ali" as I already have done a few times before. After transferring all the hardware to the new frame and connecting everything as it was before, two issues arose:

1. the battery seems dead. When plugged into a charger, the battery does not charge. But I found a useful thread which might work, so this is not the main issue.

The more pressing issue is:

2. the phone enters a boot-loop when powered up (it does not matter if I power it up with or without battery). SD-card and Sim-card are not in phone when powering up. The boot-loop consist of a short vibration and then showing the first screen "Honor - powered by android", then going dark and starting over. It is to be noted that no rooting or flashing was done to this phone.

I already tried the old display again but now the same issue arise there too.

  It can only enter "Fastboot mode" not "Huawei eRecovery". When trying to enter "Huawei eRecovery" it just vibrates really short and then does nothing.

Since the phone is still Locked and I can't power it up, my hands are kinda tied up.

  Any advice would be great. Even if it is just telling me that nothing can be done here.
