XPERIA Bootloop

Hi there!
I installed a Chainfire program, and now my Xperia have a bootloop
How can I turn on my phone? Can I flash a recovery and wipe all data, and then flash back stock kernel?
Plz help mee!

Ok, so I flashed recovery, turn it on, wipe all data, and phone still have bootloop. I don't have any idea, what can I do to flash clean stock sony firmware

Sony Update Service doesn't work. It tell me, that I have modded firmware

relock your bootloader, then use sony update service again

Ok, so how can I relock bootloader, and can I unlock it after?

Dude no need for all that. Just download Flash tool and generic Xperia ftf file. Then switch off your cell phone and press the volume down key and insert the usb while on Flash tool it will install the adb drivers if not then navigate into the flash tool folder and then you'll find a folder named drivers install the drivers from that setup proceeding ahead you should see a green led light now click on the flash button above and select flash tool and navigate it to the ftf file you just downloaded. It will install the generic rom but will remove your root access. No need to lock the boot loader. Welcome if this helped and tell me if I'm wrong

Damn working! Thanks!!!
BTW. Is there any website with ftf firmwares? Like samfirmwares for samsung devices?

AW: XPERIA Bootloop
No there is not.
Next time try EMMA if you want to reload your stock firmware. EMMA works with unlocked bootloaders (only).

[Q] Help How to flash stock rom

Guys please help
I flashed a custom rom and it got a lil messed up..
I've downloaded an ftf file but I have no idea on how to flash it.
I havent made any backup,my bad.
I'm using C5302

If you look a bit futher you will see a easy guide made by me about how to get back to stock without the use of flash tool

You have to download flashtool to flash an ftf file if you don't have any backup you lose your data but once you flash the ftf you're going to be fine

If you haven't unlocked your bootloader you can also use Sony's update service (SUS) to restore your phone.

[Q] Relock Bootloader

Hey, I've got a problem with my SP and want to repair it with PC Companion which, you know, only works with phones with locked bootloader. My phone's bootloader is unlocked. I read the post from DooMLoRD: http://forum.xda-developers.com/showthread.php?t=2354721&highlight=relock+bootloader
I'm on the SP DoomKernel v3 and I know, that I have to flash back the stock kernel, if I want to relock my bootloader. I think the (or a) stock kernel is that one: http://d-h.st/fv8
But DooMLoRD mentioned in his post, not to take the FTF file but the kernel.sin and I don't know how to extract it or from where I can get it.
Please help!

Avoid PC Companion or Update Service. Just turn off your phone and use Flashtool to flash any .ftf you want. After flashing everything stock, turn on the phone for a few minutes, then turn it off and relock the bootloader.

Okay, but the link to the Download page of the .ftf is stock, isn't it? And why shall I avoid PC Companion and SUS? my Phone apk is broken I need to repair it. Or is there an other possibility even for unlocked bootloader? I mean I only want to lock it because I want to repair. Or should the problem go if I flash a custom ROM?

If you are having a problem with an specific .apk try to diagnose why it is force closing or not working properly. Try clearing the app's data and wipe cache and dalvik cache from recovery. If the problem persist try a factory reset...if nothing solves the problem you may need to reinstall that ROM
In case of a bootloop Use any .ftf from a C5303,02 or 06...It will resurrect your dead phone. I have the stock firmware for the C5303. Its o2 branded but it works great, It has File Comander pre-installed and all Sony bloatware you could ever want. I love it! Download it from here: http://www.mediafire.com/download/nm8c4nwb7sxdblt/C5303_12.0.A.2.254_o2.ftf
If you dont like the boot animation or shut down animation you will need to root. Shut down animation is located on system/vendor/overlay. Search for
com.sonyericsson.shutdownanim-res.apk and delete it.
UNLOCKED PHONES CAN'T USE PC COMPANION OR UPDATE SERVICE. And even trying an Update OTA it may brick the phone.

Hmm.. I tried all those things but reinstall rom. But how can I reinstall the rom? I haven't got any nandroid (or other) backup before the phone apk broke. And in development section there is only the deodexed stock rom 12.0.A.2.254 and the odexed stock ROM 12.0.A.2.245. Which one of them is the right one?
Okay. I already have had a bootloop, caused by restoring an system backup, and solved it myself.
Yes, I got the advice to relock bootloader and repair with PC Companion. But if there is a possibility to solve the problem without relocking bootloader this would be really really great!

Reinstall a recovery or use doomlord's kernel (custom kernels like doomlord's have a recovery)
Reinstall any ROM you want or use flashtool to repair your phone. This will erase everything but the external microSD card.
Flashool works with locked or unlocked bootloaders.

Thank you! That helped me I'll try it very soon

[Q] How do I Lock my bootloader again and go back to stock sony firmware? :(

So im currently rooted running cm11. I really dont like it and want to go back to stock. When I unlocked my bootloader I saved my TA partition rar file which I have stored on my pc. I am quite familiar using flashtool but not that much.
In other words I want to:
1) Lock my bootloader
2) Go back to stock sony firmware
Please help me thanks
p.s if it's worth staying rooted what rom should I install? cm11 is kinda rubbish...

Flashtool will relock your boot loader and reset to stock

My flashtools not display the button "relock" after clicking "BLU", how to proceed?

Here's my solution:
Relock your TA with TA Backup from the previously saved zip file. It doesn't matter what system you use under the procedure, but remember. If you use CM11 (or any non-stock based system) do not try to power on your phone before you flash the stock firmware with Flashtool. Otherwise you can soft brick the device, or if you lucky, you will get only bootloop. And two more thing: Before you start, charge your phone's battery to minimum 50 percent, and before you really start the backup, test it with "Restore dry-run" option. If it sucsess, you can do the trick. But if it fail, re-flash a stock KitKat based ROM, root it, and try this again. If it fails again, maybe your backup file is corrupted.
This method worked on my old SL, and on my Z too, so I hope it will be help to you too.

You don't need to relock bootloader to flash a stock based custom ROM. You can flash rajeevs purexz rom via recovery after wiping system and data partitions.
Locked bootloader is only needed for some Sony stuff like Bravia engine and stock Sony screen mirroring.

Have you unlocked the bootloader of the phone? If so you need to restore the DRM keys and TA partition first before trying to use Sony PC companion to repair the phone.
If you have lost the keys and TA partition then its impossible to get it back because those are unique to each handset.
In that case you will need to flash custom kernel and any rom ( stock or CM AOSP based )
check the dev section for more

I can't flash a kernel because flash tool does not detect the phone after mistakenly flashing C6602 kernel
