Is no one reading the full thread? Any hack/exploit that requires the browser WILL NOT WORK. Somehow or another the poor OP ended up with the latest browser installed on his system. He stated his browser version is 1.7616, which is the browser that came with 10.2.0-28. No cartridge update in existence will fix his browser to allow browserhax again.
OP, you will need to find a way to update your system to 9.0 or 9.2 and then you can hopefully use Ninjhax or OOThax since neither actually depend on the browser. Ninjhax should just need a browser installed so it can download the payload, it doesn't actually make use of any exploits in the browser's code.
If for some reason neither of those work, you should be able to use menuhax to access PastaCFW and install fbi and then sysupdater, then download the complete 9.2.0-20 cia update package from that ISO site and install it with sysupdater to hopefully overwrite your updated browser with the old version that IS exploitable still.
