[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

yes i did. it was successful. i just got problems when fast boot flashing boot.img, idk what happened -_- huhu really want my sp back

In recovery (if you can enter that) perform a wipe /system and flash again This should fix most bootup issues.

Yes via Flashtool.. After that you can (if you want) relock bootloader and restore TA partition to recieve the delayed update from Sony..

do i need to connect it trough flash/fastboot mode? because it doesn't see it in the bootloop...

pccompanion only shows 2 phones in the upper left corner with download logos and nothing else at all.... (can't click the two phones btw)

Go in recovery and execute a Factory Reset or Install a Rom from recovery (iHackers, Slim or Omni). At last if you want to go Stock flash a FTF from Flashtool. Simply like that.

so now i've succeeded to install the FTF from flashtool, the software is still on a boot loop what am i doing wrong ?

The ftf included with flashtool is.not what you.need. You need a ftf firmware from the mega thread in general. Locatetyou device in post and select your regions version or the generic versions. I recommend to flash the ftf that matches with your current install.
You also can enter recovery and wipe dalvic cache and factory reset and it should boot.
If not you must flash ftf. Ensure you select to wipe all and nothing checked in excluded.

Xperia Z1 Bricked

Hi guys I seriously need help. I bricked my Z1 c6903. I accidentally deleted the OS by wiping dalvik, system, etc,. Im sorry if this was already posted somewhere here. Im new to this. If someone would kindly help me or give me help in unbricking my device Id really appreciate it.
PS, Z1 was given to me already rooted. It has TWRP recovery, and I know that Im really stupid for tinkering with the advanced option. Im new to using custom recovery, rooting, etc.

If you still have recovery , boot into recovery, mount usb and copy ROM from your PC.
Flash ROM and restart...
If you don't have recovery, use flashtool to flash ftf. (534) root it and then upgrade to 761 (latest firmware)
BTW, your device isn't bricked, there's missing system, that's all...
And yeah...that wasn't stupid at all...this things happens and, if you ask me- TWRP team should change that wipe options...
It's not well made...
First option should be only cache wipe and advanced should have format data and system option...

First of all, thanks for taking the time to reply.
I tried booting to recovery but it wont. Its stuck in the sony logo. I guess ill go with option 2(flashing ftf)
is it ok if I flash the ftf then NOT root it?
I found a guide how to flash an ftf file in this link: http://forum.xda-developers.com/showthread.php?t=2428319
is this guide applicable for the z1 too?
Thank you

You are welcome mate
Yeap...
One thing is very important - use latest flashtool..and everything will be OK.
You'll be surprised how easy that is...
Flash firmware 534 (JB)
Turn device off, open flashtool and prepare 534 firmware, start flashing and connect device (holding vol down) connect device when flashtool ask for it, don't do that right away...
root it with binary method (just Google" binary root method xda") first link is what you need.
Install NUT recovery.
Restart to recovery, flash NUT 757, TURN DEVICE OFF!!!
And flash stripped ftf (that's kernel)
It's very important to turn device off, don't restart. (to flash stripped ftf)
I always practice to hit flashtool "start" button and wait for flashtool to ask for device, that's is the best way to be 100% sure your device won't leave flashmod

well the firmware that ill be using is 257 because its branded on a carrier here on my country(PH).
do I really need to root after flashing? I was hoping that root isnt required.
is it ok if I just flash the 257 and update it via OTA/pc companion?
thank you

Well yeah...I just said that..
If you don't want to root then don't root it, just flash firmware.
I would flash latest firmware but if you are sure you'll get 757 or 761 OTA update then you can flash older firmware...

come to think of it. it sounds easy. just download the ftf then flash using flashtool.
btw. will it cause any problems if the phone has a custom recovery(twrp)?
thank you

If you do not want root just use pccompanion and choose repair my phone when the options comes up.
1 step fix!

Man, I asked you do you still have recovery and you said no?!?
Use recovery to flash stock based ROMs like NUT or iHackers, flashtool or pc companion to flash stock unrooted firmware.
It won'tbe a problem if you have twrp (recovery), it'll wipe everything...
We are talking for a two hours and you are asking same question over and over again...
I wanna help but come on....
Sent from my D6503 using Tapatalk

It doesn't have to
Turn the phone off, do not attach it to the PC
Run pccompanion, choose software update
When prompted choose the blue option to repair the phone, go through the instructions and attach phone in flashmode when prompted

[Q] Z1S system zip?

Does anyone have a flashable zip of the stock ROM for the Z1S? I must have flashed a bad zip or something because I'm boot looping and I was stupid and didn't make a backup.

Repair using Pccompanion or flash a stock FTF

Yeah, I do know that's an option but I wanted to avoid wiping my internal memory if at all possible. Thanks for the tip though!

Flash a stock FTF and just untick the wipe data option then...
Or back it up first....

Oh duh. For some reason I was on the line of thinking of ODIN where that wasn't option. I'm a little new to the Sony flash tool. Thanks for your help.

Its not the sony flash tool, that is called EMMA and only works with unlocked bootloaders
Use the original flashtool from
flashtool.net
It was developed here on xda and works with all xperia devices regardless of bootloader status
