[Nexus 6P General] ksaves2:
I used a 1000 watt heat gun. Am supposed to run the battery down till the red LED shows, then plug the unit into the charger and and let it bootloop for

5 to 10 minutes. After that, one is to apply heat in between the fingerprint sensor and the camera until the thing "magically" restarts.

I originally heated the whole phone and the unit simply shuts down while attached to the charger. Cools off and it bootloops.

I tried an icepack to the lower third of the phone to ostensibly keep the battery cool while cooking the cpu's. No dice there after 20 minutes because

after seeing the "GOOGLE" bootloop, would also see the battery charge emblem. Still did not see the device trying to boot or start as a "new" phone.

They say the heating is supposed to cause the unit to shutdown the offending cores and boot up with the usable ones. The deal is once the bootloader

is OEM unlocked and USB OR ADB debugging allowed one can reflash the phone with software that is set for Quad core support and run in a stable fashion. Cooking the whole device might cause some trouble with the lithium battery. Now my technique with the icepack might simply had been too much of a heatsink for the cpu's to get to the requisite 50 degrees C to allow the offending cores to be shut down.

Oh, I did try the "deep freeze" technique with the battery drained and left it in a deep freezer over night and no dice there either.

I will try again with the unit out side and put it between the leaves of an old, thick book and cook it again with the heat gun. The heat gun gets

plenty hot. One can't touch the metal housing of the blow dryer while it is running or they'll get burned. It's not a "hair dryer" it can melt or burn one's hair off............

And if this doesn't work, I'll do "a practice battery change" on the bum, bootlooped 128Gb unit and get it opened up. From there, I could get it into the bootloop and apply heat directly to the cpu without having to contend with the case. If that doesn't work, it's the bootloop from Hades and not likely

salvageable. I'll resolve to have fun trying to get it back and learn how to do the battery change out to prepare for doing it with my working 64Gb phone.

I'd venture a guess that the "bootlooped" 6p's on "Epay" are probably ones that the users failed to get back using these techniques. Unless one stumbles

upon an ignorant user who hasn't tried anything and just wants to "get rid of" the dead phone without trying.

I will say one thing, the 128gb 6p I got looks pretty pristine on the outside. The barcodes have a 2015 stamp so might be an early unit. I never messed with Android phones before December 2016 but worked with Linux since 1994. I do all my flashing/rooting from an Ubuntu laptop. I was lucky I read up on the bootloop issue before I got the 64Gb 6p. First thing was unlock that darned bootloader which I did. It had 8.0 on it wanted to update itself. I said heck no!

I get the stupidhead screen every time that says, "the unit can't be checked for corruption". So what! I got the proper OTA on it, TWRP'd it followed by rooting. Then got Lineage 15.1 and I'm very happy with it. SD Maid Pro zips right through a standard scan in no time while my Nexus 7 2012 and 2013 take at least 1/2 hour or more to do the same task. Kurt
