Wrong and wrong.
1) Most people in 4.5 have a working exploitable web browser.
2) You can downgrade to 4.2 and/or restore a NAND backup in any firmware using gateway's launcher as long you can get to the menu.
1.) I was mistaken then
2.) I meant using the web exploit to access gateway. I was under the impression that method was only for 9.0-9.2 with the latest gateway launcher.dat file.

I have a nand dump though.
Wait what's devmode
Misread your post, sorry. Thought yo were trying to dump the nand, not restore it.
Devmode is a mode in rxTools that basically boots sysnand without signature checks. If you are using a 3.0 nightly it might be called pastemode now.
