Help to lock BL & unroot & install stock?

Please can someone advise or point me in the right direction to lock my boot loader. Unroot and flash back to stock please.
Thanks in advance for any insight :thumbup:

Resource thread has everything you need.

I hope you have a backup of the TA partition. Otherwise it's impossible to relock the bootloader
if you have a backup though, then read here:

Oh dear I don't believe I have the TA backup.
What's my best option to get this device looking and feeling as stock as possible..... And what implications to usability does the lack of TA restore mean? Will it prevent OTA updates
Thank you so much for the insight I didn't even consider TA when rooting. Damn

You loose a few features like mirror link...
"Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader."

Thank you for your insight. So much appreciated..
So currently rooted with twrp recovery and PAC ROM.
Do I need to unroot before flashing the stock ftf?
(Using superuser as detailed by @A.android.User below)

Can I flash this stock ftf for my country (using flash tools I believe) straight from my current set up with twrp & PAC ROM?
Will the ftf also flash back the stock recovery?
Thanks again

Yes you can flash the ftf directly, and here's what you'll get:
A stock ROM
unrooted
Lose some features related to DRM keys
No OTA
Stock recovery, which is none as far as i know
This is as close as you'll get to making your device feel locked.

Thanks again for the information.
Will give this a shot really soon :thumbup:

That's wrong. You can still relock your bootloader with flashtool.

Hmmm you're right, one can still relock the bootloader, but the TA partition along with the drm keys will still be missing, which will render the relocking kinda useless.
Better said, I don't understand the reason behind relocking if you're not getting the things you lost back.
@dillalade
If you still want to do it, then here's a link showing how to relock from doomlord, so it's pretty reliable

I am guessing that OP wants to return his phone. If he is lucky, they will simply check the rooting status in the service menu and not if DRM keys exist.

Thank you everyone for the input.
If I do Relock the BL will it grant the device OTA updates or is that again TA/DRM reliant?
I just sold the phone on eBay for £200 so want to get it back to stock before I send it out tomorrow.
(Awaiting receipt of a pre ordered Z3c... there had been a significant price drop from £450 down to £350... So £150 for an upgrade seemed fair. )

You should get OTA updates if you relock bootloader. I've never tried but at least Sony PC Companian does not complain anymore about a modified device. I hope you informed the buyer that the device was actually unlocked though.

Thanks guys, job done.
Yes the buyer is aware of the phone being previously rooted.
Is it normal for Sony stock ftf rom to have empty APN settings.... if I remember correctly this was also the case when I originally purchased the phone.
Thanks for everything guys

Are they aware the bootloader has been unlocked so might not be able to do what they might be buying it for.

the APN settings get generated depending on the current service provider (currently inserted SIM card). Even then it might be the case that there are no pre-registered APN settings for that provider.
I wouldn't worry about it much
Oh and do inform us once you sell it, and get your new toy

[Q] Restore Z1 Compact to stock firmware before sending it for warranty repair.. help

Hello XDA!
I've ran into some hardware related issues with my Z1 compact (the earphone jack is glitchy) and i want to send my phone in for repairs.
The thing is i have a modded cyanogenmod firmware on it as i preferred it over the stock rom. I also have that clockword mod thing.
As you can tell i'm not very accostumed to doing these things and i was wondering if anyone would guide me on how to restore the phone to its original stock setting?
The phone is a swedish device so i would need the scandinavian versions i'm guessing, any ideas out there?
Thanks.

You just need to find the right firmware for your region / provider.
I would recommend IaguCool's thread on Xperia Firmware Downloader & Checker, if you have flashtool installed you can make your own ftf that is exactly right for your phone. All the instructions are in the thread.
Hopefully you made a copy of your TA partition before you unlocked it and put CM on your phone? it may not matter if you have not, as long as it looks stock.

Hey digesteve,
Thanks, i'll check that tool out. I don't know if i made any backups of my TA partition, but probably no because i don't know about it.
Is there a way to see if i made a backup of the TA partition, could it be stored somewhere on the phone after installing clockwork mod?
Thanks for the help!

If you didn't do it, then it won't be saved anywhere on the phone. You have to physically copy it to the hard drive of your pc for safekeeping.
It doesn't matter, it won't stop you from restoring the stock rom and I don't think not having it voids the warranty. Maybe somebody could correct me on that?

Definitely didn't do it then. Hopefully they won't give me any trouble for rooting it, it's worth a shot anyway.
I've downloaded the firmware but it doesn't come in the same sort of package as cyanogenmod, are there any guides you can recommend on how to apply this firmware to the phone?

and don´t forget to relock the bootloader with flashtool!

You'll need a copy of flashtool and the adb drivers.
Flashtool will turn the downloaded files into a tft file, but all the instructions are in the thread.
If you get lost then XperienceD's AIO thread will guide you in the right direction

I downloaded flashtool from sonys website and it actually listed stock firmwares in a list which i could apply to my phone so i did.
Now the phone boots into what seems to the be stock firmware, however i was going to go into recovery just to check that was restored too and not the clockworkmod i had previously installed but it seems i cannot boot to recovery anymore, what can i do? Where can i find the "stock recovery" that these phones comes with? I want the phone to seem as it was never rooted/changed on the software level

You have flashed the Sony rom, so now it is stock, with no root or recovery. There isn't a stock recovery. Your work is done.

Isn't there a menu you can boot to that gives you the option to wipe cache partition and do some various other stuff? Perhaps this is only for samsung devices, sorry for the confusion and thanks for the help!
Hopefully the service goes as planned!

Is still the way to do it or is there any new ways ?? I have bought a Z1 Compact for my son who is 8 and he wants it back to stock. It has CyanogenMod now.....cant recall what version though since i dont have the phone with me.

Hey but too bad is I totally brick my phone. Almost all of the solution found by google seems no used.
Out of surprise, it happened for most of the Xperia Phones who are heavy flashing with custom ROM.

Did you checked weather your Bootloader is unlocked? If not then check it.
Also try to repair your phone through PC companion.
Its a strange problem. Hearing it first time.
Did you followed exact procedure of the Guide that I linked?
I don't think it occurs due to heavy flashing of ROMs, because I have used every ROM available for the phone for almost 100 times. I usually change my ROM after a month.

The problem occurred when the user try to flash back to stock ROM from Custom ROM.
The Bootloader is unlocked.
Now the BL appear to be like this: Bootloader Unlock Allowed = No (*#*#7378423#*#*)
Enter fastboot fail (No fastboot detected), Only Flash is allowed.
To install CWM or TWRP required fastboot, so I can't do anything besides keep trying to flash wiith different version of stock FTF.
Solution I tried but failed:
- Fix using Sony PC Companion (PCC)
- Flash any version of stock ROM, inclusive of just flashed the "Baseband" only.
- Flash Acro-HD S0-03D ROM then flash back to stock ROM.
- *#*#4636#*#* -> Phone information -> Set preferred network type (any of the option & reboot)
- Settings -> More -> Mobile Networks -> Network Mode(any option & reboot)
- Settings -> More -> Mobile Networks -> Select providers (automatic or manual), it manage to detects the service providers but registered on the network failed.
- Insert other active SIM Card
I try to locate the Antenna Board but it seems like it was attached with the mainboard. Unlike Xperia Z, the Antenna Board is seperated.
I assume this problem occurred when the partition accidentally bricked by Flashtool? I did try to flash different version of Baseband, nothing seems work.
I need someone favors. Create a Pre-rooted Stock ROM(.ftf) with Recovery Accessed (CWM or TWRP).
I found somewhere from this forum stated that tried to install back any of the Custom ROM to fix the No Signal Issue which it appeared to be my last hope. Without Recovery(Required Fastboot to install), I couldn't install any custom ROM.

First of all let me clear that 'Unlocking Bootloader Allowed = No'
That means you cannot unlock it unless your coming to stock from other ROM.
Also Bootloader can be unlocked only once. So if your coming back to stock from custom, why did you tried to unlock your BL again?
Even if you flash stock ftf, you no need to unlock your BL again.
Secondly, don't try to flash other ROMs into your phone, you could mess up everything, even hard brick.
Your Fastboot mode isn't working, right? If so, then try to install fastboot drivers from flashtool driver pack. Maybe it could work.

I did not lock my BL, it just lock back by themselves. I still remember I unlock my BL with Sony Official way in 2013. After that, I did not touch that BL again. It's just after the recent flash which I did the same way like before(Custom to stock ROM), everything mess up.

My very last but not recommended solution is to change the motherboard. However, looking at the posting not only me having the issue and it mostly happened when users are flashing back from Custom ROMS to Stock ROMS.
Changing motherboard is like changing another phone, your feeling towards the phone changed.

After flashing stock ftf, the BL status always shows 'Bootloader Unlock Allowed = No' but it is actually unlocked. So it does not get relock after flashing stock ftf.
It seems like a serious problem.
Maybe, flashing other ROM will help you a bit. For that Obviously your phone must enter into fastboot mode (which is not happening). In this case did you use 'dd' command for installing recovery? If not then you could try it. And I think you'll be succeeded to install recovery and further you can flash ROM.zip through recovery.
You just need to copy recovery.img into your internal memory and enter some command's using adb shell.

You must have used a newer version of flashtool. This is causing similar issues for many people. The only solution for now seems going to Sony service center. There is another method too, flashing the TA backup, but I don''t know if it works or not.

Latest UPDATE about the issue, PLEASE TAKE NOTE BECAUSE YOU'RE ABOUT TO BRICK YOUR PHONE JUST LIKE ME. THIS IS IMPORTANT!
@hitman-xda , Please pass this message around. Btw, How to quote the name?
If everyone here in this post flashed their phones with Flashtool 0.9.19.x version, then congrats my friends, we're all become owners of bricked phones with no network signal. Flashtool 0.9.19.x versions have sript error which replaces original Ta partition leading to unlocked bootloader to become locked and loss of network signal. If you're guys haven't backuped your Ta partition prior to bootloader unlocking then that's all.

Flashing with latest flashtool flashes a partition which renders modem of the phone useless. Yes, I mean the TA partition. Each phone's TA partition is unique, so if You flash mine or other person's TA partition, Your phone would not even boot.

This is toooooooooooooooooooooooooooo OVER! It means my phone is bricked forever.
It's their mistake but we have to bear it on our owns.

Yes, nothing worked because Flashtool just accidentally bricked our Sony in the whole world. A careless mistake destroy the phone.
In 0.9.18.X, simlock.ta is always excluded by default but a careless mistake on the version 0.9.19.(1234) (at that time), The Simlock.ta is included while flashing. Each phone TA has their own unique number. Besides changing the mianboard (the only solution right now), no ones manage to solve this issue.
I wonder how many Sony phone in the world has already been bricked by this Flashtool update.
Androxyde said:
On 0.9.18.X, even if simlock is included, it is excluded from flashing
On 0.9.19.5 I did this way :
- simlock is excluded by default with a warning when including it (unticking button)
- When simlock is included, when flashing, a YES/NO box appears asking if you are absolutely sure you want to flash this unit.
- When creating bundles, simlock can be included (no risk with 0.9.18 as it is always ignored)
So if you have a TA backup, with 0.9.19.5 you can restore the 07DA unit (then reactivating the phone). Thing you cannot do with any previous release as 07DA unit is hardcoded_excluded.
I will publish another patch that will backup any TA unit that is about to be flashed. That way there will always be a solution to come back to the previous state.
simlock, if present, is always ignored in 0.9.18 release
simlock, if present is excluded by default with the ability to include it with a warning and a user query before flashing the unit
people who had issues are ones using ftf bundles created prior to 0.9.18 with simlock included. Never had issues on 0.9.18 as it is excluded by default, I forget to keep this exclusion on 0.9.19.[1234] and added a defautl exclusion on .5 with the ability to include it anyway.
But maybe it is not the right way ... I was asking myself when I did it. I want to give the ability to restore 07DA unit if ever a backup exists
The only way to recover from locked phones is to reactivate them in a service center or to restore the 07DA unit.

At least you're out of trouble. I suggest you need to backup your TA Partition just in case.
Each TA is unique and cannot be transferred.
If your TA is used by 3rd party, they may face a Hard Brick & cannot be recovered anymore.
Well, this is an added Security by Sony. They are not stupid to "share" openly for free.
Now I'm realize.

I'm already ordered the replacement mainboard.
What kind of mainboard-Lock BL or Unlock BL, I do not know because it's not a new one.
Waiting for shipment.

yess, i have ROOTED E6833 , running on MODIFIED KERNEL, (no drm keys)
and it working like a CHARM
love my phone!!!!!!
1. if you wana extract drm keys, the process is long and hard
2. if you wana just root and don't care about drm/ fido keys, then the process a bit simpler
i didnt extract drm keys! i am sad but not sorry. given any day i would have made deal with devil to have ROOT ACCESS in exchange for keys!

DRM (digital rights management) keys, by SONY CORPORATION stored in EVERY XPERIA in a allocated memory partition call "TRIM AREA" (TA)
FIDO keys are unique authentication keys by GOOGLE/YUBICO
(as per WIKI PEDIA) " Universal 2nd Factor (U2F) is an open authentication standard[1] that strengthens[2] and simplifies[3] two-factor authentication using specialized USB or NFC devices[4] based on similar security technology found in smart cards.[5] While initially developed by Google and Yubico, with contribution from NXP, the standard[6] is now hosted by the FIDO Alliance.[3][7]
the problem is to have root access on Z5P running on MM (kernal 3.10 or higher) you must FLASH the kernel. and flashing kernel can only be done on UNLOCKED BOOT LOADER. WHEN you unlock your bootloader, sony by default WIPE the following from INTERNEL MEMORY
1. all user data
2. photos /logs / apps
3. wipe TA partitions (so the all keys are GONE)
i never had oneplus, but all i know that SONY XPERIA falls in the devices which are the hardest to root.

You've been so helpful! Thank you
One last thing. What differences could you see after and before rooting it? Battery life wise. Speed. Everything? Just a general view.

with ONLY having ROOT ACCESS, it will
1. will give you better control over your hardware, and you can change sensitive settings (CPU CLOCK etc) (not recommended though)
2. control over disabling removing XPERIA APPS ( whatsnew, software updater, lounge, xperia mobile transfers,
3. Control over other system apps locked by SONY ( GOOGLE PHOTOS, Hangouts, DRIVE, BOX,
4. Clean my Delvik Cache etc whenever i want
5. control battery draining apps and their wakeups by controlling apps like PURIFY
6. backup/restore KEYS (DRM/FIDO)
with having ROOT ACCESS + UNLOCKED BOOTLOADER
all above and
1. flash custom KERNELS having RECOVERY (something you can BOOT into bypassing Android)
http://www.howtogeek.com/wp-content/uploads/2016/01/twrp-backup.jpg
2. flash flashable .zip apps from recovery (custom made themes)
3. change android ECO SYSTEM ICONs etc via recovery
4. install CYNOGENMOD (if available, as of now there is no CM for Z5p)
5. Install MIUI (when available)
6. flash other MODIFIED ROMS

need some help :D

i have a sony xperia z5 p [e6853] and my bootloader is unlocked but i havent done a backup before do it and now i want update the SW to new version. how i can restore original sw for fix my drm and resove my sw? if i send in assistence they can restore all?
soz for my bad english

once bootloader is unlocked!
drm keys and TA partitions are lost
nowthing can be done now!
only sony factory can put YOUR DRM keys back to your mobile!
however
now you can used modified kernels , which fakes drm keys in kernel itself

Yeah I use simulated drm keys and it works fine.

are there some ez guide for install a custom kernel like original?
