There's a 6.20 TN-D permanent patch out, so it goes to follow that there will be one for 6.20 TN-E too, right? That's what homebrew developer Frostegater recently released.
Before anything else, please be warned that there have been bricks reported when using this app on a PSP Go, although there have also been others who have successfully used it. The coder himself has only tested it on a Fat TA-081 and a Slim TA-085v1. Before using this app on your PSP, be sure that you have ways of recovering from a brick. Please check this thread on Wololo's forums for further details.
This patch should apply a permanent mode to Total_Noob's 6.20 TN-E. It will install 6.20 TN-E onto your PSP's flash0 so that every time you reboot the HEN doesn't get wiped. You can discuss this and other homebrew releases on the QJ.NET PSP forums.
