Fastboot issues. - Xperia Play Q&A, Help & Troubleshooting

Sorry if I'm spamming.
So I flashed my kernel to a ics format. Lupus. But I tried flashing my kernel to a JB format so I can flash to a JB rom. The problem is I can't get my phone into fastboot mode. I was told to flash back to .62 baseland. Question is how do I do that? Please any help will do.
Thanks in advance.

Use flashtool, drag the ftf into flashtool, untick all except baseband and flash it.

This won't lock my boot loader back up right? Oh and thanks for the reply

No it won't. This will just change your baseband.

thanks i really appreciate it

Not really, unless someone creates a flashable zip with stock fw using a rom creator and transfers it you by bluetooth, but that would be stupid because in the time it's taken to transfer a bluetooth file you could have put on a computer, run flashtool, dl'd the stock ftf, flash the phone, gone to a pub and had a beer
Thank you for the prompt response.

that wouldn't work as you can't flash kernel via recovery

I cant seems to update OTA. Im using fw.42,bseband-64,kernel.283

maybe cause your phone has rooted..you can update using flashtool if you have the fw62.ftf,and yes you can flash kernel using flashtool,but make sure you're in fastboot mode..

I'm pretty sure you have to have all modded files in system back to stock

Flash kernel via flashtool?

Maybe a stupid question, but as I am used to flashing via fastboot, which doesn't work on my windows xp, is it possible to flash a kernel via flashtool, and if so, how?

Xperia Play custom kernels

I just unlocked my boot loader and was wondering how do you install a custom kernel. I have searched for a thread about it but I wanted clear instructions. Also can you tell me what you think is the best kernel and rom combo? (For r800x CDMA)

The only cdma kernel is Doomkernel.

Before flashing a kernel i want to make sure i get everything right so i dont mess up my phone. Do i flash the kernel first or the rom and what is the baseband someone told me you need to flash this as well and if so where do you get it?

Kernal before rom always baseband is your network. Most of the time the roms o.p will have a link to download the baseband which you will flash after you install the rom
So its flash kernal using fastboot install rom using clockwirk mod recovery then turn phone iff enter flashmode and flash baseband should be good to go
P.S FLASHTOOL is your best friend

Order doesn't matter, just phone won't boot if kernel and rom are not same android version, fixable by doing the other steps

And what did you do? How did you flash it? The correct command is fastboot flash boot boot.img

Have you correctly installed fast boot drivers and have you tried flash tool and do kernel that way
