These chips are NOT flashable. It says so if you read the description entirely. However, if you fail to do that and just rely on reviews, you will most likely be disappointed due to the fact you are paying flashable prices for a chip that is not. Other than that, it works just fine, use a hdd under 120 Gb.

Waste of money
Can’t upgrade the bios…
One of them
Didn’t work at all
Lesson learned buying from these 3rd party sites

I bought this modchip from HHL based on a well respected YouTuber's install video on Cerbios. I've done many modchip and softmod installs on Xbox's since the early 2000s and the installation on the Aladdin was by far best experience. But when I went to Flash Cerbios to use my 8TB drive, I quickly learned about the dreaded mislabeled BIOS chips.

Fair Warning: DO NOT ORDER IF YOU INTENT TO UPGRADE THE BIOS.
For instance to use Cerbios for larger HDDs.

I don't know HHL that well yet. This was my first order with them; but I assume it's the fault of the factory in China why these batches wrongly labeled chips made it into the Aladdin's. I've given HHL my information and hopefully I'll get a working chip ASAP.

Works if you don't plan on going larger than 2TB
as other review states bios is not upgradable

Managed to get it installed in about an hour or so, and it's been working perfectly for me! I wish the guide had a bit clearer directions though; the part where you solder d0 to ground is a _very_ small pad. I lifted it on the back, but thankfully, there's an equivalent (even smaller!) pad on the front that it can go to. Got it to work, but was very touch-and-go for a second. The installation instructions should be clear that you'll need a very fine-tipped iron here. Other than that, it's a great product.

I purchased 3 Aladdin XT chips an none of them are able to update their BIOS which is a huge problem if you want to upgrade to a hard drive larger than 2TB.
