Just for a test, I copied the 1.2.1 update (which is just a cert file and a little script to install that cert) without upgrading from 1.1.1 to 1.2 first. UYK was grayed out. Then during the upgrade to 1.2 I noticed something interesting -- unlike the "update_install" process (when running my scripts), this 1.2 update draws a pair of little icons at the bottom of the screen when it first begins the update -- icons showing battery charge and radio signal strength. But they disappear once "installing" begins.

The next step (firmware flashing, now in progress, is slow) will be to install the cert (1.2.1) update, then return all the books to the previous owner, then deregister.

Ah... it rebooted, and then displayed "Firmware Update" at the bottom of the screen for awhile. But now changed to "Starting the update...".

I am curious to see if the previous owner deregistered this kindle at their end (in their amazon account). If so it should deregister automatically after applying the cert update (the radio is ON -- no risk if a K1 only accepts UNSIGNED update.bin files).

Rebooting now... Ooh... it says "creating base system... initializing... done..."... Rebooting -- did it eat all the books before they coud be returned to increment the license counts? -- Reboot complete. Still "Michele's Kindle" and still full of books. I wonder what that "initializing" was all about.

Still "cannot connect at this time". New cert still needed. The cert update also shows the battery and radio icons at the bottom of the screen. My update.bin files (that run "Big Buck Bunny" and stuff) do not show those icons on the other kindles (FW 1.0.8 and 1.2).

Cert applied, still registered (even with radio on). Hmm, on a K1, I see no option to return books, only to delete them. On the PW2, of the 135 books on it, most could be returned, and only a few only allow "delete". I wonder if there is any benefit to deleting books -- will their license counts be adjusted a the owner's amazon account? I am suspicious because going to the Kindle store says "welcome, guest" even though this K1 says it is registered.

I think maybe the previous owner may have deleted their amazon account... Though I already backed up this K1, so deleting those books will at least free up some space. I have more ebooks in my collection than I can read in a lifetime already...

My concern is that unlike returning a book, deleting it might also delete it from the registered account -- not sure how that works.

I decided to do a factory reset. That should be safe for the device and the previous owner's account. Hmm... no factory reset in the menus. I must delete all the books one by one? Or write an install script to whack the partition?

Ahh, the "content manger" lets me process whole pages of book titles, at least. I can "remove" them, or move them between SD card and "kindle memory". Except that "remove" option DOES NOT WORK (at least not when all items on a page are selected). They are still there after multiple "remove all" attempts. Except now I can no longer "Select All", so maybe they ARE gone? I see a "Refrehs Lis of Items" option. Nope! Still there, but I can no longer "Select All". Though after sorting them, I can "Select All Items on Page" again. But after selecting. "Remove Selected Items" is greyed out this time, and it oly lets me "Deselect" or "Move to Kindle Memory" (which is funky considering there is no SD card installed) -- or do they mean "Move from the amazon account", in which case "deleting" them really DID return them to the original owner?

I wonder why there is no obvious way to do a factory reset...

EDIT: After returning to the HOME page several times, now it suddenly has only four books on it, so apparently the deletes just took a few minutes... I just went to the content manager to delete those four books, and ALL the books (both pages) show up there. So it must be showing me books on the amazon account too -- so they WERE returned, it seems. Except those four books. ... Okay, now all items returned. Nothing on Home menu. But content manager still shows all books with option to "Move to Kindle", so they must be only in the previous owner's amazon account now. TIme to deregister... Okay, deregistered warned I may want to transfer subscriptions with the account manager -- done. No device name or owner on this K1 now. All books returned to original purchaser. All is well...
