Well this is weird as hell.
So I deleted one of my games, an update patch from another game and a demo so I could try and download them from the eShop. The first thing I tried was going into the settings to check for game updates and it crashed to a blackscreen and then the system turned off. Weird.
--------------------- MERGED ---------------------------
Ok so it was a random glitch. Second attempted worked.
With a N3DS XL on RX-9.5.0-28U (updated NVer) and using HANS I am able to access and download demos that released before 9.6, as well as redownload games I already own from the eShop. At this time I cannot fully test purchasing a new game as I have neither the funds to do so nor a game I am willing to buy.
Updates, however, will not download through the eShop. Attempting to download one resulted in the 007-2920 error that others have been getting.
Might be worth noting that on attempting to exit HANS/eShop back to the HBL (holding L + R + Down + A), the hbl crashed back to the home menu for rxTools, where I had to actually turn the system off and restart it for things to work properly again. In addition, the HANS/eShop shortcut in the HBL was very buggy. In addition to the weird hard crash I experienced the first time I went into the eShop, I had two other attempts to load HANS that resulted in weird hangs or crashed before even loading the eShop. I wonder if something is messed up with it because of the changes made by smea recently.
edit:
So updates can be downloaded normally via the home menu still.
Launch FreeMultiPatcher and apply the patches (make sure the fw spoof patch is active), then attempt to launch the game needing an update. When notified of the update, Press "Y" to updated, then click "Download Now". Doing so will sign you into your NNID and then download and install the updated without going into the eShop itself.
edit 2:
Since the weird crashes and bugs lead me to suspect a problem with HANS, I am going to try using an older version from before the recent updates to all of the homebrew stuff.
