[Q] Can't flash a kernel on my play - Xperia Play Q&A, Help & Troubleshooting

Hello,I'm new to this, and I can't seem to flash any file,especially a kernel using flashtool.I've installled my drivers,including Flashtool from DooMLorD and other relevant files,and when I want to flash a kernel,all I get is "ERROR:device needs to be rooted" in every attempt of flashing a kernel,even though I've already rooted using the ZergRush method.What am I missing here?I even tried flashing Kieran's DarkForest kernel without success.

You need an unlocked bootloader to flash custom kernels.

Thanks,now I've done that.Now I'm having problems connecting to my pc after unlocking my bootloader and flashing the kernel. :/
LOL nvm that I fixed it myself.

Hold the search button whilst plugging in the USB it should go blue then you can flash stuff in fastboot

Thanks but I've decided to relock my bootloader after countless problems.Looks like I'll have to stick to SEMC for now just to be on the safe side.

im on the same boat as you i want to relock my bootloader but im not sure if i can and i dont want to try until i can get an answer. i unlocked it using the sony ericson website. can i relock it using flashtool?

Yeah you can relock with blagus' .ftf using flashtool. But I don't see why you would want to relock the bootloader

Agreed I totally loved it when it was unlocked and running on Kieran's DarkForest's kernel and ROM but the performance of the phone,especially when playing music and other media, just got worse with stuttering and all and my phone bricked,so luckily for me I found a way to relock it and reinstall the official firmware.As much as I want to unlock it,its safer to go with stock,in my opinion.

But you can use stock software with the phone unlocked as well...

Really?I've been having force closing issues from SE's apps like eventstream and all those since I've unlocked my bootloader and from there it got incredibly worse with audio issues and stuff.And one thing though,when I unlock my bootloader,should the phone be switched off cuz all those issues came up when my phone was on.

Unlocking the bootloader doesn't cause any if those issues you described you probably installed a crappy Rom, I use stock Rom and install a kernel it's all really stable then. Unlocking the bootloader causes the phone to lose DRM which stops facebook likes and stock track id (new one is usable) and also prevents official updating (Until you relock the bootloader again)

Yeah the official updating really helps for me since its the easiest to use for unbricking my phone,which is why I was hesitant on unlocking it again.Last time round it nearly hard bricked my phone after a bad flash(probably).Plus I couldn't even connect to SE PC companion when it was unlocked.

[Q] Can we get CM7 with locked bootloader?

Ok so I read on other forums and CyanogenMod forums that it's somehow possible to get CM with LOCKED bootloader, by using the root exploit like gingerbreak, downloading ROM Manager and installing the mod. The question is... can we do this too on Xperia Arc? Because I really like CyanogenMod7 but I don't want to unlock the bootloader because I will lose the DRM Keys. Yes I know, I can unlock it without losing DRM Keys but that costs and I don't wanna spend any money. So, can we get CM7 with locked bootloader on Arc?

Try it, and let us know.
The problem is that I have the 0% battery problem, and I flashed the 1% patch. Will everything work okay?
Ur heading the wrong way mate
No cm7 with locked bootloader no matter what u download
Goodluck wit ur batt issue
Sent from my LT15i using xda premium
So it's not possible on arc... if I'll try and anything bad happens, reflashing the stock firmware will fix everything?
Can't say it will fix ur phone as I've no idea what u intend to do
What I'm saying is u won't get cm7 with locked bootloader
Sorry mate
Sent from my LT15i using xda premium
I intend to install CM7 using ROM Manager and root without unlocking bootloader like here http://forum.cyanogenmod.com/topic/5143-install-cyanmod-wout-unlocking-bootloader/
Rom manager uses cwm which u won't have or get by installing rom manager
Rom manager is an app to run cwm from phone not a work around way to flash roms
Cm7 uses its own kernel. It will not work on stock kernel and u can only change kernels wit fastboot.
Fastboot is only enabled by unlocking bootloader.
Best I can explain it
Best of luck

Ok so maybe these guys on N1 made it but it was cm6... Maybe it was easier... Anyway... Should I unlock the bootloader? What will i exactly lose if I'll do this? I mean, what apps/functions will stop working by removing the DRM keys...? I heard one of them would be TrackID
Sent from my LT15i using XDA App
Honestly not sure done mine and haven't missed anything that was removed.
Heard track Id ( I use soundhound)
Also seus and ota updates won't work/dangerous to use
I can't say one way or the other but I'm on miui wit 1.2 oc and love it
Up to u mate
Enjoy
Sent from my LT15i using xda premium
Does anybody knows what exactly apps/functions I'll lose by removing the DRM keys beside TrackID, SEUS and OTA correct functionality?
Ok so by removing the DRM keys I read I'll lose trackID and the "Like" function in the native music player. Is that true, or anything else? As the SEUS and OTA functionality can be fixed by relocking the bootloader

In Need Of Some help here with re-locking bootloader

I know this may have been discussed already but I have quite a bit of a messy situation here. After Unlocking the bootloader, I clearly realised that something was really wrong with my hardware, so I decided to send it for repairs. Sadly, re-locking the bootloader using that .ftf file that Blagus had shared and re-installing the official ROMs aren't working somehow. I meant that PC Companion and SEUS claim that my phone has the latest softwares after I tried to relock the bootloader and update it via the services as above mentioned. Couldn't get them to work, especially after flashing ICS Kernels by Doomlord and KieranFTW and also the ICS ROMs supplied. Anyone know how to help? I know that if I don't relock the bootloader there's no way of using that warranty of mine...

flash the stock rom doesnt relock your bootloader.. flash this http://www.mediafire.com/?g1b5j712ajx4yjd file using flashtool.. and thats it

R800a unable to go into fastboot mode

So after Sony announced that ICS will not be coming to the PLAY I decided to install CM9 but I can't figure out a way to get into fastboot.
I remember getting into fastboot when rooting my phone but I forgot how.....
I looked up the issue online but nothing really worked out.
I've tried holding down the search button and plugging in the usb but there is no blue light!
btw I have an Xperia Play from att unlocked and rooted with R800a rom(Global firmware 2.3.4).
U using flashtool? Is yoir phone powered off? Are you even sure you looked this up?
Sent from my R800i using XDA
Maybe this is already answered in between a stream of comments but it happened to me too. (I flashed 2.3.3 R800a in a R800i then updated via OTA then got flash mode only and no fastboot).
If you unlocked using SONY's method (fastboot oem unlock 0x...), and then reflashed using SEUS or MediaGo, even FlashTool then updated via OTA or the formers, and after that you get flash mode only (green light, back button pressed when powering) then you should try flashing this, as original firmware checks for unlocked BL before booting and disables fastboot if unlocked.
After that you can still re-unlock BL.
Good Luck!

[Q] Sony Xperia Arc S won't boot up.

When I try to boot it up (using the power button of course), the LED above the USB connection place flashes green, and the phone vibrates once and does nothing.
Any help would be appreciated, thanks.

I found the issue; can't use SEUS after you unlock the bootloader. Thanks anyways! All I did was flash a rom that relocked my bootloader (?? don't know the terms), and then run SEUS again.
you cant relock a bootloader with a rom.. you need help fro this thread. download a ftf firmware and flash t using flashtool so that the phone boots p and then check the bootloader status .....later depending on it, flash a custom kernel and rom (optional though recommended)

Whoops, guess I meant I flashed an FTF... lol. Something I found on YouTube.
But yeah, I've run into another problem; while rooting the phone (using this guide over here: http://forum.xda-developers.com/showthread.php?t=1683957), I think I've bricked my phone again. I didn't enable USB Debugging and Unknown Sources, so it got stuck at Daemon Started Successfully. Haven't been able to boot into my phone since. Sorry if this problem has been solved before, wasn't able to find the solution while searching that thread.'
EDIT: ...sorry again, managed to stumble my way through and revive my phone.

Update Service with an unlocked bootloader is a bad idea.
Try this.
http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
Official flashtool to go back to stock rom.
And as the guy above told you, SEUS on unlocked bootloader is a bad thing.
Hi. I have same problem.
Just flashed FreeXperia rom and gapps. Phone wont to power up. Just geting blue led or green.
Any clue? My bootloader is locked.
tried to use official xperia update tool but it wont to recognise my phone (maybe i doing sth wrong :/)

Dude,
As the others have said you cannot install FXP CM10 on a device with a locked bootloader.
As such your device will not boot, your options are to either.
1) use flashtool to flash a stock rom - instuctions how to use flashtool can be found on the forum
2) use Sony update service to flash back to stock - This is the easier option, but all your data will be wiped.
Once the device will boot up, if you still want to use FXP roms then unlock the bootloader first, or try a rom for locked bootloaders.
Either of the above should work for you.

yea phone works again fine on the stock
At least you show others, do not flash custom ROM if it's only for unlocked bootloader.
If you have locked bootloader you can't flash custom kernel and you will stuck in bootloop.
