Firmware 5.17.1 and HF binaries

[BionicGecko]

I took the plunge and updated my KO3 from firmware 5.16.2.1.1 to the newly released 5.17.1, and it seems I am not able to get the jailbreak back following Marek's instructions for HF firmwares. I installed the non-HF hotfix and installed the 5.17.1 update, however I am unable to successfully run the HF hotfix to complete the procedure.

I'm not asking for help (I was aware of the risk when I ran the update), I just wanted to give a heads-up to anyone potentially planning on updating their Kindle that the new update might not play nice with their jailbreak for now.

Some more details:

• Uploading the Update_jailbreak_hotfix_1.16.N_khf_install.bin file to the root of the Kindle does not bring up an "invalid update file" error when ejecting the Kindle, however attempting to install it from the Kindle UI results in an error message saying that a problem occurred and the update failed.
• Uploading the Update_KUALBooklet_hotfix_f190a38_install.bin file to the root of the Kindle does bring the "invalid update file" error. The other KUAL .bin files (install and uninstall) don't register as update files (no update menu item shows up).
• Trying to install the hotfix via ;log mrpi doesn't work - MRPI won't start (the Kindle just actually searches for the string in the books). I made sure to have Marek's updated MRPI binaries for HF installed in the extensions folder, but I believe those require a working KUAL.
• ;log runme also doesn't work, either with the downgrade script or for the emergency-bridge-recovery script.
• ;711 however does work, so it doesn't seem that all ";" commands were disabled.

Did you do two simple restarts after update?
Do you see log messages under the boy under the tree during boot up?

Not right after the update, but I've rebooted many times since while trying various things. Now I just tried rebooting twice in a row without any operations in between, just in case, but I still ran into the same issues afterwards.

Unfortunately no, there is no *** JAILBREAK *** message or anything.

You can check whether ;log r command still works using emergency-bridge-recovery.zip from the Jailbreak archive (NiLuJe's snapshots).

Here are six methods to try to downgrade (sorry, you need to translate it):

DO NOT UPDATE TO 5.17.1 it kills the hotfix and thus your jailbreak...

Many thanks mergen for your support! So it seems ;log r doesn't work either; apparently all ;log commands are gone.

I went through all the methods in the post you linked, and sadly nothing helped, including the steps to restore the ;log commands, which were giving me hope The trick which worked for me last time, i.e. to put both the KUAL installer and the hotfix in mrpackages, won't help this time around as ;log mrpi doesn't work.

One thing I hadn't seen before, although I doubt it's helpful: it seems that rebooting with the hotfix bin in the root (instead of trying to do install via the Kindle GUI) brings up an "UPDATE ERROR: 2" message on top of the screen, besides the standard "user friendly" message that a problem occurred.

It does look like the jailbreak is gone. Oh well...

Indeed I found that out the hard way Thanks for the confirmation Marek!
