I have an almost new Paperwhite. It's not the 2018, very new waterproof one, but the previous model (version 9?). The serial number is G090 G105 **** ****

Before seeing this thread I stupidly updated the firmware to 5.9.4. Is it possible to JB the device?

I've tried using the factory install to put 10.0.1 on it but it doesn't recognise that as a valid update. This might be because it's registered and I didn't do a reset before trying? Or it might be something else.

I realise this must have been asked before - sorry - I did look for a specific thread. Any help JBing the device will be greatly appreciated!

Thanks
