Hey community,

I think I have fully, irreparably bricked my N4. Here is my situation:

  • I was running the latest nightly of OmniRom
  • My battery was dying quick so I wanted to try and use Franco Kernel
  • My USB cable wasn't working so I needed an on-device way to flash
  • Francos latest kernel (209) is in a .img and not flashable .zip
  • I found a thread (which I can't find now) suggesting I dd if=boot.img of=/dev/block/mmcblk0p6
  • I get into adb shell over wifi and issues the command, but I make a HUGE mistake and miss the "p6" when copying (wrote the image to mmcblk0)
  • I panic and issue a reboot command

My phone will no longer boot. Even the 'recovery' way of holding volume down and power for 15 seconds only results in a single red pulse of the LED and causes my computer (Manjaro linux) to print the following error in its logs:

qcserial ttyUSB0: usb_wwan_indat_callback: resubmit read urb failed. (-19)

Is there anything to be done for my phone short of sending it off for repair? I'm a Canadian living in Peru and to get the N4 fixed I think I'll need to send it back home to Canada and then have someone there send it off. I can't even buy a new phone very easily because the cell phone market in Peru is so expensive. Even if I buy a new device on Google Play and have to get someone from Canada to send it to me in Peru and the import taxes could be as much as the phone.

If you can't get it to boot you're pretty much hosed. I'm not even sure what partition mmcblk0 is. For the future, don't use dd commands unless you really know what you're doing. If you'd issued the right command the 0p6 partition is the boot partition and it probably would have worked.

You're probably stuck with jtag right now

But, check out the flashify app. It would have flashed the kernel correctly.

    If you have a wall charger, try letting it charge for awhile and see if you can boot into the recovery.

Yep, I had the command right but I copy-pasted wrong. One of those moments when a non-existent 'enter' is pasted into the terminal window.

No luck, unfortunately.

Looks like I'm in the market for a new phone. *sigh*

Overnight. I'm thinking this red light is the Red Light of Death and not the read light of dead battery - it doesn't pulse, it only pulses on once and then goes out again.

Looks like JTAG is my only option. I think I've found a place that can do it in Lima. Anyone have any idea of JTAG services in Peru? (That might be a long shot). Thaks all for the suggestions and advice!

    How long did you charge it? If only the N4 would charge as fast as it discharge....
