[Q] Always stuck on Splash Screen

I can't find anything about this on the Xperia Play forum so I have to ask now, I just unlocked my bootloader, SO glad I did, but it seems that after playing with some kernels, I can't even get past their splash screens! I've used LuPuS, FXP, and Mjolnir. It'll show the splash screen, vibrate and the led will light up. I've tried holding volume down and leaving it alone. Nothing happens, it just sits there. ADB says no device is plugged in as well so I can't try adb reboot recovery. I'm going to flash the R800X 2.3.3 FTF then reflash the Mjolnir Kernel, flash it's Wifi module, then install Glazed ICS. If anyone knows why it does this, I don't plan on turning my phone off UNTIL I know a solution to the stuck splash screens. Thank you!
EDIT: It starts doing that when I restart into recovery from the phone, I forgot to mention that, I haven't just rebooted the phone's system yet. I'll try that and get back to you once I install Glazed.
EDIT2: I powered off and booted for the second time and it didn't get stuck. I guess for the time being, I'll stay away from Reboot Into Recovery on the phone and just use the recovery-play.img.

Okay, now my phone needs to be reactivated... Can't see the number pad so I have no way of pressing One. Help please???
EDIT: I'm an idiot, I had to activate it while it was on stock gingerbread first.

Generally, after you flash a room, in that rom zip file the kernel is the boot.img, you need to extract and flash that boot.img so the rom would be able to boot.
First install FlashTool, in the flashtool folder there is a driver file to install the ADB drivers for Xperia devices, select all the drivers that apply to the Play to install.
Enter flash mode (hold Search button).
Flash the kernel: fastboot flash boot boot.img
If all fail, you can use Flashtool to flash the stock tft file to restore the phone to factory state.

Had the same problem, dial *228, instead of pressing one (since the dial pad is not yet visible) just stay on the line and they'll activate it. That's how I got mine activated.

[Q] Xperia ION Bricked

I was trying to root the Xperia ION phone.
I followed all the the steps mentioned(HERE) & flashed the kernel available HERE.
BootLoader is unLocked
Now after flashing the kernel, the device had gone in bootloop mode.
I could access the recovery, but thats it.
When i tried to boot to system from recovery, it once again started bootloop.
So, from recovery i wiped the whole system partition of my fone {wipe data}.
Now there is not bootloop, when the phone starts it just gets stuck at SONY logo & after that it doesnt go any further.
While starting it displays a pink LED, so i can go into recovery by pressing VOL-UP key & from recovery i can go into BootLoader FastBoot Mode.
But i cannot get the green led to get into flash mode.
I dont know which type of bricked device is this HARD or SOFT BRICK.
But please help.
What should i do further so that i can again use the phone.
Currently the phone's battery is completely dead.

What firmware version were You on? I think using old kernel with new firmware made Your device soft brick. Try using a kernel which is of same firmware version as Your's.
Did You install drivers for flashmode? Because You need to flash the Your official firmware ftf via flashmode.
Else if You are able to access Your device on pc while being in recovery, find a rom with kernel in it and try the command:
Code:
push /pat/to/ROM.zip /sdcard
and then flash the rom.

Thanks buddy.
But i already solved the issue.
By going into the flashMode nd flashing the stock firmWare

[Q] 'Secure boot Error!' at boot, download mode and factory reset don't work

Hello,
Here is what led to my issue:
I rooted my phone using this method: http://forum.xda-developers.com/showthread.php?p=38886073#post38886073
Downloaded clockwork rom manager.
Here comes the thing I don't remember. At least i know that the last thing i did was to click on 'backup current rom'
After this the phone reset itself and this message came up:
Secure booting error!
Cause: boot certification verify
Then i tried to reset using the power button, which led me to the 'battery full' screen - afterwards i was able to reboot. As stupid as I am I just tried the same thing again. And ever since i am stuck at the 'Secure booting error!' screen.
I am unable to enter download mode. I get to the 'Hard factory reset' screen, but if i accept doing so, it says 'Secure booting error!' again.
I also remember clicking on 'restart into recovery mode' at some point, but this is not the last thing i did.
I am really desperate. Please, help me!

Well i had the same issue today... It happened after i did two changes. One of them was to to try to relock from freegee and flash twrp again from freegee. In my case i was able to go in download mode and flash original kk rom with lg flash tool.

Unfortunatly, trying to boot in downloadmode, i still get the same error :/

How are you trying to boot into download mode? And what factory reset screen? It seems as though you did not unlock the bootloader using freegee, if you make any changes and relock the boot loader you will get that error. But it seems that it has not been unlocked. If you hold power and volume up what happens? Same thing when power and volume down, one of them is recovery (possibly factory reset you are seeing) and the other is download mode. I don't remember right now but you should read the whole softbrick thread and see if you are missing something. You may need to use LGPNST to go back to stock, you can also use that program to flash a new recovery so read carefully and follow all steps.
When this happened to me I was able to flash an unlocked bootloader and it allowed me to use my phone again as it was before doing something stupid (for me it was an attempt to re lock the bootloader).

well, i managed to get into download mode. Obviously i used the wrong method to get into download mode...
I used this method and everything worked fine, so far. : http://forum.xda-developers.com/showthread.php?t=2249500
My phone doesn't boot now. Fast Boot doesnt work aswell.
All that happens is a white battery showing on the screen and when i try to fastboot all that happens is that the LED is blinking or glowing red after some while.

What do you mean when you try to fastboot? Fastboot is basically the bootloader and allows you to select recovery or download mode. What you should have done after following that thread is go to recovery and wipe everything and flash a new ROM.
If you are saying that the bootloader is not coming up and allowing you into recovery then I believe something was missed.

After trying out some varioants of this it worked: http://forum.xda-developers.com/showthread.php?p=40274560&highlight=red+led#post40274560
I wiped the phone, but since I had to leave over the weekend i just turned it off and went away.
Now that I am back, nothing works now :/ The Phone doesnt react to anything, not even donwload-mode.
Is the battery too low maybe? It's on the wall now for a few hours, but it still doesn't react. It's not warm either.
edit:
when i charge the phone, i will get a 'watchdog bark' after some time allowing me to get into recovery. accesing downloadmode from there doesn't do anything. strangely, the recovery isnt trwp although it should be because teenybin comes with it. it's 'bbs.gaodi.net' which doesn't have a sideload feature. what do i do now?
edit2:
after 10000 tries i got into download mode. i don't want to **** up now so i won't do anything until i know exactly what to do.
any advice?
edit3:
got it working by flashing another teenybin which included trwp - then i installed miui via sideload. i don't have signal though, but i will open another thread for this since this is another issue.

I think I hardbricked my Zuk z2?

So guys
I was on twrp and tried to flash a new rom but when it rebooted after the install, my Zuk z2 died.
It does nothing now. If I press the powerbutton for a long time it shortly vibrates for one second and the notification light also lights up for 1 second, but does not boot up. I tried volume combinations, don't work either.
What can I do guys?

Well, this guy managed to fix it
. Not sure if its the best way to fix it but it's still something

Use this if you didnt success from other methods.

My video. The brick occurs when you usually backup a room with one version of twrp, flash another variant of twrp and then restore the nandroid from before.
Happened to me. Flashed MIUI, and then tried to restore a nandroid (not realising the TWRP changed).
Hope the video helps. Plus then you have a cable premade in case it happens again

Hello. Maybe you can give me some advice. I am stuck in engineering/diagnostics mode after I accidentally selected that option when I was in the bootloader trying to flash TWRP.
Basically, I had installed TWRP and Mokee 7.1.1. I wanted to check out the original chinese ROM so I relocked, flashed with QFIL, etc. I had first flashed MM, then I flashed latest chinese Nougat official.
I didn't like it, so I was trying to unlock the bootloader again, and in the process I ended up selecting the diagnostics/engineering mode. The phone was stuck there and I had no way of accessing the bootloader to reflash with QFIL or MiFlash
TO try to fix, I used the deep flash method you describe in the video, only I found it in zukfans. I was able to open the 9008 port, flash with QFIL/MiFlash. Even though both tools describe the flash as successful, on boot, it goes back to engineering mode.
How to I get out of there? Is my phone done?
Thanks!

Question Sometimes brick

Hi maybe somoene has some further knowledge for my strange predicament. Whenever it try to install a fastboot asop rom the phone drops to EDL mode with black screen and i need to hold power plus vol down for over 1 minute to get the phone back into fastboot mode otherwise it will remain in EDL with qusb 9008 something lik ethat showing in dev manager. This all happened when i tried to switch from one asop rom to another without first flashing stock rom via Miflash. I think maybe something became corrupted because that is not the way to flash ASop rom but i was taking a shortcut thinking it would work because fastboot format all script wipes everything but clearly not system area. As it stands now i am on Eu weekly but i do not want to be stuck in this position and i would like to be able to flash other asop roms as they become available. There was a very kind developer on telegram who remotely assisted me in getting my phone working again but he shall remain annonymous. I am worried that maybe i have corrupted fastboot which is why the phone is dropping into EDL mode when trying to flash Asop roms. I did install EU via TWRP nebrassy i guess i was lucky that worked but just before installing that rom i tried to install Arrow os which i had on previously but when i tried to boot into Arrows recovery to do sideload this time the phone just went into EDL and i had to do the hold power and vol down for over a minute thing again and then in fastboot flash stock rom via mi flash to get things working. Hope someone can shine some light on my issue.
