I am on 5.16.2.0.1 now, so any next update is incompatible with JB.

Jailbreak does survive even 5.16.5 (should, tested on .4) however most of it wont work, only developer key and dispatch will work which means you can execute shell files as normal and install hotfixes as you want, the only reason nothing works on these versions is the switch to hardfloats, updating toolchains to support this chains is on nilujes todo list, looking at the downgrade extension and compacting it into a single file will let you modify the version file and downgrade to anything you want do what you want with this information im currently looking into the inner workings on oobe

Thanks Marek!

Can you please point me in the right direction for the Downgrader?

Any other precautions I need to do (while I have JB) to make JB survive?

[mergen3107]

On PW3 FR 5.9.7 I remeber there were some scripts (stratup and oobe) in etc/init , but I never tweaked those being afraid to brick it.

Here's the file i used just earlier today to downgrade my KT5, all it does is modify the version file and reboot, you can then just sideload the official update and reboot

as for other tips, i guess you can pray if you want


MAKE SURE TO NAME IT "RUNME.sh" -- All capitals

1) KUAL opened OK in demo mode.
2) ranameOTAbin didn't work it seems (see RUNME.sh method below)
3) USBNetwork neither - don't status of USB network upon hitting the button.
4) Battery status doesn't show anything too.

However, I am able to run the script file RUNME.sh placed in the storage from the ;log runme in the search bar.

I first put these in the script:

#!/bin/sh

ls /usr/bin >> /mnt/us/renameOTAbin_log.txt

It showed me that the binaries are not renamed.

I'll go an try renameOTAbin with this script.

Thank you so much Marek!

My plan now is to see if properly renaming OTA will "trip" the oobe guy and it will let me in.

If not, I will proceed with the downgrade...

that may work go ahead an see, at worst it will use the initramfs updater and install the update anyway. at best you get an update error and boot into a oobe free kindle

RUNME.sh guy to rename OTAs worked! Let's see...
(understandably, each time demo mode is loaded all demo user content is reset).

UPDATE: Do NOT repeat these steps, see https://www.mobileread.com/forums/sh...&postcount=476

So it seems downloading it somehow (I can see it in the network log), it just doesn't show the progress anymore

Marek, what if I spoof the /etc/version.txt the other way, making it higher? Then the update will be happy, I guess and won't offer to update?

I have no clue

Alright, a warning to everyone:
please don't do it as I did!

I got stuck in the semi-demo mode after I renamed OTAs and then did ;exit_demo (;demo just brought me the usual demo config settings, not the one to quit it).

So I was greeted with OTA-broken oobe AND locked Wi-Fi settings so I coulnd't open Browser...

Doing factroy restore and starting over.

the way to really get out of semi demo is either ;demo (normal) and pressing resell device

Thanks Marek!

I will give it a try to spoof the /etc/version.txt (with runme.sh) to a higher number, and see if updater would skip it

UPDATE: DON'T, it breaks the hotfix packages as well: https://www.mobileread.com/forums/sh...19#post4374819
