U-Boot Kirkwood and Linux Kernel 4.2 Kirkwood (3 replies)

A great person, bodhi, helped me about a half year ago rescue my pogo E02. I had spent years, on and off, trying to get ssh access to it.

Now, I want to do two things:
1. http://forum.doozan.com/read.php?3,12381 (U-Boot Kirkwood)
2. http://forum.doozan.com/read.php?2,12096 (Linux Kernel 4.2 Kirkwood)

I know 2 will give me Jessie. I faintly understand the benefits from 1. And given the grave warning bodhi gave in that thread, I have stopped for two reasons; I don't want to brick this unit and in respect for the time of those who may try to help me unbrick.

I have attached two images from the first portion; 1.
The first is I did not get the expected output from running: nanddump --noecc --omitoob -l 0x80000 -f mtd0 /dev/mtd0
And the second, I can't be sure, since my NAND error check gave errors, whether they are located within the first 1MB of my NAND.
By the way, is it possible to 'clear' up the NAND of such errors?

And this is where I have stopped on 1. I have not started 2 yet, waiting to complete 1.

Related question: can someone please confirm for me that 2 will give me Jessie, and throw some light on the need to do 2. As well, do I need to do 1; could I get 1 from just doing 2?

Finally, I feel like stopping now and putting a new and bigger USB stick in there. I have now: rootfs version 3.16. How can I migrate to a bigger USB? Can I just take the current one out, restart with a new bigger one and install Jessie? What commands would I run, if so?

Thanks a lot for your help. Much appreciated.
