I have a Google Nexus 6 (Telus/AT&T) and I had been successfully running the Lollipop version of Chroma for months now.
Yesterday I flashed Chroma Marshmallow ROM, and the recommended Google Apps, along with the MRA58K bootloader. Everything went well and I successfully booted into the ROM. After my apps were restored, I rebooted the phone and everything worked just fine.
This morning, I used Titanium Backup to restore my back up of Adblock. After it restored successfully, it prompted me to reboot. Then the phone shut down and I haven't been able to turn the phone on. I am not even able to get into recovery.
Not quite sure what has happened here. The phone rebooted successfully several times since the successful flash. I have had my Nexus 6 charging for quite a while now with the stock USB cable and adapter and still nothing.
When I plug my phone in to my Win10 PC via the USB cable, I get nothing (it would register before).
Is this a sign of flashing the incorrect bootloader? How can I tell what is actually wrong? Is my phone bricked?
I have checked the Chroma thread and even made an XDA post requesting assistance. But there have been no leads so far.
Edit to answer @unforgettableid questions;
- When you charge your phone, does any LED light up?
No, no LED lights up. Mind you, no LEDs would light light up on a stock Nexus 6 anyhow.
- When you hold down your phone's power button for ten or fifteen seconds, what happens? Does the phone vibrate (signalling that it's getting ready to boot up?) Does the screen's backlight turn on? What do you see, hear, and feel?
Absolutely nothing happens. No vibration, no back light. It is like the battery is dead, however it has been charging for well over an hour now using stock cable and adapter (plugged into AC)
[2015-11-10] Edit to answer additional @unforgettableid questions;
Please plug a battery (which is not full) into the phone.
- Can the phone successfully charge the battery? Does any voltage travel between the phone and the battery?
Not sure how to plug in a battery to the phone. The battery in the Nexus6 cannot be removed.
- Do you happen to own a clamp ammeter?
I do not.
- Do you happen to have access to a thermal-imaging camera?
- Do you happen to have access to a JTAG box?
- Does your phone have JTAG pins? 8. How hard are they to access?
Not 100% sure, but it sounds like you shouldn't need to go that route with a Nexus 6.
- Please boot up Linux. Enter
lsusb. What do you see? Enter
dmesg. What do you see?

I also tried this approach but even after installing all of the drivers, I do not get a response when the Nexus is plugged into the PC, and thus can't rescue it.
