Is it charged?

 

I had the same issue a few days ago. Stuck it in my phone and switch to charge. Didn't work. Plugged it into a USB port on my pc for a few seconds using the cable it came with, lit up again.

 

Try plugging it into a PC to charge.
Edit: Nevermind

 

Might be worth it to hook a power supply up to it and see if it works, May just be a dead supercap. On that same train of thought, maybe open it up and check for cold solder points.

 

are you still able to boot cfw with it?

 

well, mine sometimes doesn't charges and still boots

 

I do mean it refuses to work flat out, it's a mini paperweight, I just bought a ns atmosphere off aliexpress for like £8.60 but it'll take a little while to get here, guess I'm stuck to my phone for now

 

Try leaving it plugged in to the PC with the included cable for awhile (~1hr). You have time while waiting for the new one anyway.

 

This may sound a bit random but worth a shot. A lot of SX Pros were turning up DOA but this workaround made them wake up.

Use an alternative method (RCMSmash, NXLoader) to get into an RCM Bootloader (SX, Hekate etc). Now plug your SX Pro in and boot into your CFW of choice.

My SX Pro woke up as my console loaded into SX OS for the 1st time but was dead as a door nail before that despite me trying to charge it via Micro USB or an external USB C charger.

 

just use your PC Download tegrarcmgui and the sx os payload.bin

or just use your android phone and download sx app (on sx os webpage) and use a OTC adapter to run rcm

my dongle has been broken for months and I just rely on my computer /laptop/phone
