hi @kwchik ,read this article carefully
When using this method, you will need to work backwards from the oldest pending transaction in the queue that you want to cancel . For example, you cannot attempt to cancel a transaction with a nonce of 10 before canceling nonce 9.
To make sure your cancellation request is picked up as a priority, and before the original, you will need to pay more for gas. On this screen, follow these instructions:
- Set your gas limit comparable to or slightly higher than your original transaction.
- Set your priority fee to at least 10% higher (in Gwei) than the gas fee of the original (pending) transaction (e.g. if that transaction had a gas fee of 30 Gwei, set the max priority fee in the replacement/cancellation transaction to 33-35 Gwei).
- Make sure your max fee is at least 30% higher than the max fee of the transaction you’re replacing. For example, if your previous fee was 150 Gwei, choose something nearer 200 Gwei this time.
Hi Tuya, I can send another 0 ETH transaction with high gas fee for nonce 1, 2 and 3. But cannot set this for nonce 0.
My pending transaction is nonce 0
hi, according to the guidelines of the article, can’t you fill in the Custom Nonce as 0?
I use Copy & Paste Function to Paste “0” to nonce field.
But finally the transaction has error: “ replacement transaction underpriced “
well, did you follow the instructions in the mobile section of the article to set the Advanced options? 
to make it easier to succeed, you can set it a little higher than that.
Wow, problem solved, Thanks a lot.
Please Paste “0” to custom nonce filed. Because we cannot set 0 by used “+” and “-“ button
Great, glad your issue has been resolved. 
Also, thanks for your suggestion, I will submit it to the team.
