[Q] R800i won't boot after kernel flash - Xperia Play Q&A, Help & Troubleshooting

I've tried to install cm9 onto my play so i did the root part,the bootloader unlock and installed cwm then i flashed doomlord kernel v14 per flashtool and typed in the fastboot commands fastboot -i 0xfce flash boot boot.img and fastboot -i 0xfce reboot and now the phone starts but the screen stays black and i wasn't able to shut it down.I can't start the recovery menu but flash and fastboot mode work and also the flashtool recognizes the play's standard usb connection,Then i tried some different kernels but none brings me further than the sony boot animation till the screen goes away.If it helps i followed a instruction team android for cm9 on xperia play(sorry can't post the link).
Could some one help me with this problem?

Doomkernel doesnt work on cm9 and Doomkernel only works on stock gb. You need a cm9 kernel. Sorry bud you flashed the wrong kernel. =/

Unlocked bootloader, bricked due to flashing

Hi.
I've unlocked my bootloader last night successfully, and went on to flash a custom boot.img.
First I did "fastboot.exe flash boot boot.img", it went through no problems. However after that, my phone boots up to Sony Ericsson logo, it goes away and screen remains black.
I've tried to flash generic global ROM ( "fastboot flash system boot.img" ) to see if I can at least restore my phone to default ROM, it still acts the same..
Anyone mind helping ?
fastboot flash boot boot.img - flash kernel
fastboot boot boot.img -hotboot kernel
what file you flash for rom?.ftf or img?if .ftf you need flashtool,but for .img just use fastboot

I've used "fastboot flash boot boot.img" as my first step.
The file was .img, obviously.
Flash it back to stock with FlashTool and try it again.

Heh, I haven't realised that .ftf files flash the entire thing INCLUDING kernel to the phone. Oh well, we learn every day
Thanks guys !

[Q] Can't get anything other than cm9 to boot

Hi everyone...
I recently installed the latest cm9 on my ARC.
I want to install cm7.2 again, but I can't get it to work.
This is what I do:
1) fastboot the image file (fastboot.exe boot boot.img)
2) Install the zip
3) Clear data/cache
But it just hangs at the CM 7.2 logo.
If I install CM9 again, everything work fine.
Any ideas?
fastboot flash boot boot.img
from the ARC

Exactly!
With fastboot boot command, you simply make the kernel boot once.
Fastboot flash boot will do it for you!

Thanks guys... I suspected it had something to do with the flashboot command. I'll try it out ASAP.
EDIT: It's working now, thank you

[Q] Xperia Pro flashing

So, finally I have managed to unlock my bootloader in ADB with the sony's method, I did this because I want to try out the ultima rom with kernel.
So I have never flashed a kernel, I only used wotan client and flashtool. I don't know how to start.
I have everything (latest android sdk, proper drivers, battery full, root, clockworkmod, kernel.img) only the knowledge how to do it SAFE, and the most important how do I flash it back to the original ramdisk and kernel?
PS.: I have an Xperia Pro MK16I,
Is there no guide in the rom thread?

Dude, the same Ultima ROM thread has the instructions.
It's always the same.
Flash Kernel via Fastboot> Flash ROM via CWM> Full wipe.
You'll have to get the fastboot files from somewhere to flash the kernel.
Once flashed the Kernel, to flash the ROM the most common command to bring up CWM is pressing Vol - several times.
After that, you just flash the zip from Ultima.
That's it.
Unable to enter recovery mode
I am unable to enter the recovery mode by pressing the volume - key. How can i enter the recovery mode ? i am stuck on the sony logo.
I was flashing a ROM on locked bootloader and already had clockworkmod recovery. Now i can not access it

Sony stock recovery cannot be used to flash recoveries (Even you can only boot into stock recovery using ADB commands).
Firstly you will need to flash CUSTOM recovery. this can be done via fastboot commands.
fastboot flash recovery recovery.img where recovery.img is the name of your custom recovery. (you will need fastboot drivers and platform tools, if you arenot sure what I am talking about ask in details)
Next you will need to flash kernel via recovery by holding volume+down button while sony logo shows when you restart your phone.
Or simply you can just flash kernel directly via fastboot commands without any need to flash recovery
Good Luck!

Thanks, i figured it out. I downloaded the DooMKernel's recovery and flashed it with the flashtool. Thanks

No more recovery or fastboot.

My device is an Xperia Xa1 Ultra G3223.
Long story short, I was on rooted Android 7.0 with magisk v16 or 17 don't remember and TWRP. I was unable to update my firmware using the system so I used XperiFirm to get the latest firmware from my carrier. I used flashtools to built a .ftf for branding I wrote Sony and version I put 48.1.A.2.101. I did a factory reset then flashed it.
Now I can boot into android no problem but if I try to enter recovery it just reboots into android using adb reboot recovery. And if I try to use adb reboot-bootloader it just boot loops and the only way I can get out of it is to hold vol down to enter flash mode and reflash my .ftf. I tried using flashtool to enter fastboot but it still boot loops.
Now I'm at a loss for what to do. I was going to try and flash a kernel and recovery from another thread here but I cant do that. Is there a way to flash a kernel/recovery without fastboot or something ?
Thank for any help
Ok well i finally got it working again! I tried using Emma and that updated me to 116 but i was unable to get to the bootloader. Funny enough i unplugged my phone from the usb hub i was using and plugged it directly to my pc i was able to get to the bootloader. So i re flashed 101 and then flash a kernel and a recovery and all is good now no more bootloop when i try to go into the bootloader.
