Non-official Boot9strap CFW Method for R4 B9S Made from R4I-SDHC.COM

Posted on 29th Aug 2019 @ 4:19 AM

Dear R4wood users,

Recently users are complaining about when r4i-sdhc.com will update their CFW software for R4 B9S chip, they got CFW error after Step 12 following official guide, as shown below.


Indeed, official CFW files work fine, however, 3DS system blocks it since 10.8.0-41 update. R4I-SDHC.COM has not officiallly released their fixidation up to now.

Here r4wood share out non-official CFW method if your console has been in 10.8.0-41, 10.9.0-42 or higher, we tested R4 B9S on O3DS Ver 11.11.0-43E. This method should apply to other 3DS system versions.

a) Software preparation

b) CFW Flash

1, Replace official installfirm with the one downloaded above

2, Follow official guide till complete step 5 successfully

3, Switch from official guide step 5 to non-official steps now

4, Insert your source SD card into your computer

5, Delete boot.firm from the root of your source SD card

6, Copy boot.firm from the Luma3DS.zip to the root of your SD card

7, Reinsert your SD card into your device

8, Power on your device

9, Your device should have booted into the Luma3DS configuration menu

10, Use the (A) button and the D-Pad to turn on the following:

  • “Show NAND or user string in System Settings”

11, Press (Start) to save and reboot to continue the finalizing-setup

  • If you get an error, neglect and just continue the finalizing-setup
