Unlimited "Scan & Repair" Fix For Battle.Net Launcher (Warzone & Black Ops Cold War)


The infinite loop of "Scan & Repair" is one of the most common issues that players face with their Call of Duty: Warzone and Black Ops Cold War games when launching via the Battle.Net launcher. Now it has once again returned for Black Ops Cold War players right after the most recent patch.

If you have played the new Outbreak mode on Black Ops Cold War, you must have come across a random game crash with the following "Fatal Error" message.

You would have pressed the "Scan and Repair" option from this Fatal Error (like any normal person would do), which leads to an unlimited loop of "Scan & Repair" in your Battle.Net launcher, not allowing you to enter the game. You then might be shown yet another error with the code BLZBNTAG00000BB8 (the code might differ slightly depending on which game it is happening for you).

Normally, you would press the "Scan & Repair" option by clicking on the gear icon next to your launcher's "Play" button. But, at this point, even it won't work.

Blizzard Customer Support suggests deleting the .IDX files in the data folder of your game directory. However, you've likely arrived here because that solution doesn't always work.

The easiest, yet most unpopular, method to solve the "Scan & Repair" loop is to simply re-install the game. However, installing 200+ GB of game files is not something anyone wants to do if it can be at all avoided. In this guide, we show you exactly how to fix the problem without re-installing your game. In the guide we do it for Black Ops Cold War as an example, but the method also works for Warzone and other Blizzard games associated with the Battle.Net launcher.

  • Step 1: First, go to your game directory. The easiest way to do this is by clicking on the gear icon next to your 'Play' button and selecting the 'Show in Explorer' option. It will directly open up the game directory. Note that you will be one folder outside the main directory. Click on the folder with the same name as your game you're trying to fix.

  • Step 2: Delete all the files in the directory except the 'Data' folder. Don't worry, you won't have to install the complete game again as we are keeping the 'Data' folder to avoid re-installing the complete game. Select everything except the 'Data' folder and delete.

  • Step 3: Next, you must delete all the .idx extension files from the 'data' directory. Open the 'Data' folder and inside you will find another 'data' folder with a lower-case 'd.'

    Sort the files by pressing the 'Type' column, and the .idx files will come on top. Delete all the .idx files that you see in this 'data' folder.

    You can also search for ".idx" using the search bar at the top right corner of your windows explorer. It will show you all the .idx files that you need to delete.

  • Step 4: Once again go to the 'data' folder inside the parent 'Data' folder and sort the files in ascending order. This way, the files will be sorted from smallest to largest size files. Then, delete everything that is smaller than 2 MB. Do not delete anything above 2 MB.

  • Step 5: Restart your Battle.Net launcher, and your game should automatically start scanning and repairing. This time, it will not stop in the middle and won't show any error messages. It will go on to complete, and you will be able to see the "Play" button instead of the "Scan & Repair" button.

  1. You’re an actual legend for this!!! Thank you!! I tried countless youtube tutorials but none of them seemed to work. Your solution worked for me

  2. I did this and it worked thankfully, so I thank you for that.... but now I'm downloading 100GB of "files" it says... must've deleted some wrong files maybe?? Really don't think I did though, fairly easy step-by-step process.

    1. Hi Charizzma! That's odd because I downloaded only 150-200 MB worth of data after doing this step which is pretty much all the files we deleted. If you keep the parent 'Data' folder, you shouldn't have to go through such a huge download.

  3. Thank you so much! I've been trying to find a fix for this issue for 2 hours now and this worked like a charm! You are awesome for this. You're cooler than the other side of the pillow.

  4. I’m surprised they don’t use this as the actual guide in how to fix this glitch. Spent and hour trying to fix it before finding you. After one try at following your instructions it was instantly fixed. Thank you so much

  5. Hello friend, i have tried your solution in my battlenet, but the issues i am facing is that a 200 mb warzon update is stuck on remaining 240kb, the internet speed is still active not stuck but nothing is happening, and now it's stuck on scanning, everytime i open it it runs scanning automatically and does not stop

  6. Hello again, i commented before but i don't know is my comment got posted, so basically the method of scanning of repair worked perfectly, but the error BLZBNTAGT00000BBD is still here, it's a remaining around 262kb of an update, that are not downloading, i did every solution suggested by the internet and still stuck here, please if any possible solution available tell me about it. Thank you

    1. Hi Jean!

      I'm glad the scanning and repair issue is fixed for you. And, sorry to hear that you're experiencing the update issue. Here's a suggestion that might fix it for you. Try changing your region from the main Battle.net launcher. Sign out, then change the region, and then sign back in. Also, change the region from the option located by the 'Play' button.

      Hopefully, this will fix the issue. You can change your region back to your original region once the game finishes downloading/updating. Good luck!
