Late-last year, many folks reported of a software issue where the Huawei Nexus 6P entered a bootloop stage where the device wouldnt proceed past the Google Logo upon firing up the device. Not even factory resetting the device would fix the issue.
An unofficial fix has come from XDA members: XCnathan32 and rchtk. The fix required you to download and flash a few modified system image files which circumvent the bootloop by disabling the larger CPU cluster. For some reason (which is still unknown), the larger CPU cluster isnt let the phone function properly, so the modified boot.img file only lets the phone use four of its eight CPU cores, which means youll notice much lower performance.
Regarding the bootloop issue, Google never issued an official fix but instead stated that customers should RMA their bootlooping devices for a replacement. Of course, those who were out of warranty or were in an unserviceable area can at least revive their dusty paperweights using this workaround.
