Try to (exactly)
IF THE PHONE IS POWERED ON
1: remove the battery
2: keep BACK pressed while reinserting the battery (KEEPING BACK PRESSED)
3: wait some seconds (KEEP the keys pressed)
4: the phone should be in fastboot mode
IF THE PHONE IS POWERED OFF

If this is not working for you, maybe you flashed another SPL and/or another radio.
I've written a lot of posts recommending not to change the SPL because it seems 1.33.1008 or 1.33.1009 are the latest (at the time of writing) like the corresponding radios.
I don't have any image for this SPL or radio version and I don't know a method to recover from a bad SPL.
I hope your problem is not a hardware or SPL related and you'll be able to get fastboot mode.
