Recover hard-bricked Max Lumi 2 - Page 9

Code:

edl /u0 /w /s0 /c0 backup0.img
edl /u1 /w /s0 /c0 backup1.img
edl /u2 /w /s0 /c0 backup2.img
edl /u3 /w /s0 /c0 backup3.img
edl /u4 /w /s0 /c0 backup4.img
edl /u5 /w /s0 /c0 backup5.img

So why does /w (write) take those other arguments?
Because reading is harmless. Writing is dangerous.
What if you wanted to flash the boot partition:

Code:

edl /u /w /pboot_a myboot.img

Ok, but what if you forgot to type /pboot_a?

Code:

edl /u /w myboot.img

That would smash your boot image across the GPT and all the partitions at the start of the LUN. So I make you say /s0 (yup, I want to write starting at sector zero) and /c0 (yup, I want to write the whole LUN).

Okay, I did that, and now it's bricked, again?!
So, the last time root didn't work so I thought I should start fresh.
Now, every time it boots, it shows tablet is starting up sequence, forever.
I'm positive there is nothing wrong with my backup image, I administered the backup process thoroughly.
I did try to make adb work by flashing your recovery, but the same splash screen shows up.
Can you please help me?

I thought you were asking as a matter of interest not of utility. Although that would have hardly made a difference.

If you didn't mix your backups up and if they hadn't got corrupted somehow and if they went in without a problem, then there is only one possiblity besides hardware problems.

Did you at any time "factory reset" or "wipe data"? That would be "fastboot -w" or some action under the stock recovery.

I did, from the settings menu.

Smacks forehead. You deleted the keys to decrypt your userdata. All that information is gone and it will take a quantum computer in the year 2100 to restore it.

Recovery should still work from the restored backup. But you need to flash misc-recovery to misc to make it go to recovery.

You can try "fastboot -w" now to see if you can get this thing to do a fresh start (without your userdata). But if you haven't already invalidated your backed up userdata you will have then.
