Okay I've gotten as far as being able to Downgrade IOS15, and then when I try to install IOS36 patched, it keeps saying:
ES_AddTitleStart returned: -2011
You need to use an IOS with trucha boy.
That's what the IOS15 downgrade is good for...
Then the install fails.
do what it says. after downgrading ios15, you must use it for patching ios36. select ios15 for TBR to use for patching ios36.
edit: ok follow this (from tj_cool's post at CSG):
QUOTE2. Run Trucha Bug restorer. You will see a screen with a lot of text. Wait for the small message to appear at the bottom and press 1. (Don't press it before that!)
2a) Time to downgrade IOS15
* Leave the option at IOS36 and press B (no IOS reload).
* In the next menu, choose Downgrade IOS15.
* It will ask where to load the IOS from, choose Download IOS from NUS (if you follow the Offline guide, choose Load IOS from NUS).
It will go back to the HBC when finished. Run TBR again, wait for the text and press 1.
2b) Change the IOS to IOS15 and press A (NOT B).
* Now go in the IOS36 menu.
* Leave the top option to 36 and change all other things to yes.
* Once you did this, go to Install patched IOS and press A.
* It will again ask where to load the IOS from, so say Download IOS from NUS (if you follow the Offline guide, choose Load IOS from NUS).
It will go back to the HBC again so run TBR, wait for the text and press 1.
2c) Change the IOS back to IOS36 (if its not set to that) and press A.
* This time, choose Restore IOS15.
* If it asks you where to load the IOS from, you should know what to do by now.
