I tried I have 5.1.0 and this doesn't works on that. any alternatives or any way to downgrade ?
I have 5.1.0 and Checkpoint works great. I wrote a instruction to follow.
1) You need SD card (any size), USB Type C cable and jig or paperclip
2) Download Checkpoint -
https://github.com/BernardoGiordano/Checkpoint/releases
3) Download CFW folder from
Hekate-SDFilesV3.zip
4) Download Payload from there -
https://gbatemp.net/threads/hekate-with-fixed-sleep-mode.506254/
5) Copy all folders from Hekate-SDFilesV3.zip to your SD card
6) Copy
Checkpoint.nro to switch folder in your SD card so put in your Switch
7) Download TegraRcmSmash from
https://switchtools.sshnuke.net/
8) Put Switch in USB Recovery Mode, known as RCM by use paperclip or jig on right rail and hold the volume + and power at same time, so your Switch will be in black screen
9) You have to follow their instruction to install the APX driver by run zadig (you can get one from
https://zadig.akeo.ie/), look for APX and find libusbK (v3.0.7.0) to install the driver.
10) Drag the payload to TegraRcmSmash
11) Look at Switch screen and find CFW to run
12) Go to Album so wait for Homebrew to load
13) Run the Checkpoint
14) Select the game of your choice
15) Follow onscreen instruction to extract the save file by click on Backup and input the name of your choice *For example, Pika*
16) Turn Switch off and take SD card out
17) You can find save file starting with switch folder > Checkpoint > saves > *Game Name* > save folder name that you input in Checkpoint like Pika for example
18) Download save of your choice to replace the existing save or make a new folder to put new save in, same as above.
19) Use restore via Checkpoint to inject the save into game
