Hello!
Could you please help me to identify what I might have done wrong during the jailbreak of my Kindle Oasis.
I’ve followed the procedure step-by-step and didn’t have any problems in the process up to step 8.
The nickname of my Kindle is KOA (G0B0GC), it is not a special offers model. So I’ve successfully downgraded Kindle with
KOA factory_KOA_5.7.4_initial. Before that I’ve performed factory reset and after the factory reset I’ve registed Kindle in Amazon and put it into the flight mode.
Step 5 has been done without any problems but as a result I didn’t get any identification from the device that it has been jailbroken (no message, no new document).
Step 6 has been done successfully.
Step 7. I’ve downloaded
customer_KOA_5.8.7_update and installed it by placing the file in the topmost, visible level of USB storage (alongside of /documents) and updating the Kindle through Home -> Menu -> Settings -> Menu -> Update Your Kindle. Kindle has been updated successfully.
And now Step 8: I’ve copied the 2 folders (extention and mrpackages) from
MR Package Installer to the topmost, visible level of USB storage (alongside of /documents), ejected Kindle and run the search bar command:
;log mrpi. Nothing happened. The device didn’t restart.
Than I’ve downloaded
KUAL package and copied
Update_KUALBooklet_v2.7_install.bin to
mrpackages folder, ejected Kindle and run the search bar command:
;log mrpi. Nothing happened. The device didn’t restart, new documents didn’t appear.

What should be my next step?
Should I perform the factory reset and start from the beginning? Is it safe?
Or I should just re-perform step 8 some other way?
Please help! It is my first Kindle and I so want it to be perfect!
