Help: Reset KOA3 and cannot install jailbreak hotfix through update menu

xyrompec · 07-21-2021, 01:21 PM

I reset my Kindle due to some problems with whispersync, then found out that I forgot to rename /usr/bin/otaupd and /usr/bin/otav3 back. I got past installing kindlebreak. Now I'm stuck unable to install the JB Hotfix through the update my kindle menu.

Using ;log runme I was able to list /usr/bin, but I couldn't copy my backup file over to /usr/bin.

Any help is appreciated!

Never mind, I think I solved it by running mntroot rw before copying.

I had literally the same issue, I went to reboot, was super tired and not paying attention and accidentally reset instead of restart (I want to punch who thinks putting restart next to reset was a good idea)

UYK was greyed out with either hotfix, I got it to work by putting the JB hotfix and KUAL update bin into the mrpackages folder and doing ;log mrpi in the search, after that everything seems to work fine again.

On firmware 5.13.6 and here's the specific files I used:
Update_KUALBooklet_44a61b6_install.bin
Update_jailbreak_hotfix_1.16.N_install.bin

Adding this info here just in case it helps anyone else
