[Q] Relock Bootloader Help - Xperia Tablet Z Q&A, Help & Troubleshooting

I've had a couple of PM's asking for an FTF of the 10.1.1.A.1.253 SGP321 LTE firmware, but I've already unlocked the bootloader (rooting failed), so when I use PC Companion to repair the device, it give the "modified software bugger off" message.
Whats the fastboot syntax to relock the bootloader? I'm guessing something like "fastboot -i 0x0fce oem lock", but pls advise.
Some posts I've read seem to indicate that after relocking you have to reload the firmware, but will PC Companion allow the repair? Or will it detect that its "relocked" and tell me to bugger off again?
Guidance would be greatly appreciated.

Relocking via Flashtool 0.9.10.2beta6 worked fine, didn't wipe device.
Using PC Companion, Sony Update Service, or Sony Bridge for Mac failed to repair (no updates available), so firmware cannot be downloaded.
However, Sony Flashtool (EMMA) does allow firmware to downloaded & installed to devices with unlocked bootloaders.
FTF for SGP321 10.1.1.A.1.253 will be available soon.

[Q] Fastboot mode

Hi everybody! I'm new at this forum, i come from xperia x8 forum, and I have problems with custom kernels. I have a xperia Neo V, and I just cant connect the phone in fastboot mode. I'm not sure if it is properly bootloader-unlocked, as in the oficial sony's webpage it said that cdma devices cannot be unlocked (check http://unlockbootloader.sonymobile.com/), and I think that is the standard in Europe isn't it? (I'm from spain). Also, I checked the service menu and it also indicates that the bootloader cannot be unlocked.
Anyway i tried through the testpin-s1 tool method and everything seemed to work fine, i got the output with the two lowercase "r", but not the messages showing the model, software version, custom version, filesystem version and serial number, as said in vimjam's guide (check the post regarding unlock BL here: http://forum.xda-developers.com/showthread.php?t=1409269).
When I try to connect it in fastboot mode it just shows the sony ericsson logo and starts to charge, not showing any blue led. I know that this happens in locked devices, but the two lowecase "r" in s1 tool indicate that it is unlocked, so i dont understand... Can someone tell me if my phone is properly unlocked, or if custom kernels can be flashed connecting the device in flash mode (as it does work for me)? Thanks in advance
Eventhough your bootloader is now unlocked, your fastboot is still locked, you have sim-locked phone and you need to pay to unlock it.
ok, so you mean I have to sim-unlock my phone in adition to bl-unlock to connect it in fastboot mode? can this be done in wotanserver or i have to take it to some tech service?

[Q] Updating Android with 'Bootloader unlock allowed: No' using PC Companion

Hello!
I want to flash a custom ROM on my Sony Xperia phone, but the bootloader unlock isn't allowed. I know the solution for it, but since unlocking SIM lock would cost at T-Mobile Hungary 15000 Ft (about 48 €), I thought maybe PC Companion can do it this way, too. (The official Android updates also just 'flow through it' to the phone.) So I've selected Repair sotware in PC Companion. It downloaded some files, the actual software is likely to be here: C:\ProgramData\Sony Mobile\Update Engine\db\13740270\blob_fs. Here are (among others) 3 files beginning with 'FILE_', ending with a 9-digit number (they don't heve extensions). I could decrypt them with Flashtool (Tools -> Bundle -> FILESET Decrypt), so they must be the OS insaller files.
Now, my question is: how could I do this reversed? So, if I have a custom ROM, how can I convert it to a 'FILESET'? If this was possible, PC Companion might be able to flash that ROM on the phone. It would be a much easier way.
I hope this is possible - I'd welcome any ideas connected to the problem!

FAILED (remote: Command not allowed) flashing recovery or boot img

Hi,
I made a different thread to find a solution about this error I got when I try to flash the Androkernel boot.im and TWRP recovery on my UNLOCKED BOOTLOADER Z4 712 wifi european tablet.
I updated with the Sony PC Companion tool, I DID NOT turn ofn the MySony Security (that was THE problem that caused this error last time), and bootloader is still unlocked (checked with Sony Mobile Flasher).
The service mode say "root:unknow", in previous tablets/room it should say "bootloader locked or unlocked", but I'm not sure.
That's what I got when I tri to flash boot.img:
C:\>fastboot flash boot boot.img
sending 'boot' (32584 KB)...
OKAY [ 1.633s]
writing 'boot'...
FAILED (remote: Command not allowed)

First of all it's not polite to create new thread in android development part. Here should be only roms, fixes, patches recoveries. Not q&a threads.
As to your problem, are you sure that you've unlocked bootloader? In service menu you should see
"Rooting status:
Boot loader unlocked: Yes"
if you doesn't see it, it means you haven't unlocked it or unlocking is not allowed on your device.

Hi,
I think the problem is here if you enable myXperia before or after unlocking the bootloader ( can be @AndroPlus can explain better the problem ?)
Verify that your USB drivers for fastboot and adb are correcctly installed (install the USB drivers provided with Flashtool)
I hope you can root your tablet again :good:
I'm very sorry if I opened the thread here, feel free to close or move it, but I found it related the modding and , actually, in installing the androplus kernel.
As I said I did not turn on the sony security nor befor nor after, root status is "unknown", Flas Tool say is't unlocked, I already flashed the androkernel before and the problem was the MySony security, but now I know I don't have to turn it on.
Drivers are Ok, I flashed the new rom with Flash tool and then with Sony Companion.
Anyhow, if I'm bothering with this thread pleas close it, al try again and again
I think it's okey moderators will move the thread over.
Did you unlock your tablet by flashtool or follow official Sony instructions?
Do you have myxperia app installed?
Have you got factory reset after unlocking?

Do you have myxperia app installed? yes, but it's not enabled! Actually it's not an app, but an option in "security" menu.
Have you got factory reset after unlocking?

yes, I reinstalled the new rom with flashtool then with Sony Companion and root status is "unknown".I can try reflashing it tomorrow.maybe someway I got stuck in a unknow situation between locked and unlocked X-(

First of all, I don't really understand how he was able to update something via pc companion with unlocked bootloader?
No ota update, nor update via pc companion is available after unlocking.
DHGE will we have the same? I mean when android MM will be released, we flash it and will it be with myxperia? And if we launch it by accident we break our tablet, right? In this case, how to remove it, factory reset?

I read about a guy thoblem because after updating with Companion bootloader was relocked, he unlocked again and so.
Anyhow,I just NOT UPDATED, but RESTORE/REFRESH the firmware flashed with Flashbout a bad flash with Flashtool. Immediately after the flash with compsnion,even without turning on the phone, I try and I got the same FAILED (remote: Command not allowed)
:crying:
I even relocked and reunlocked bootloader with Flashtool (didn't even know it's possible to relocked...).Thi lost :-/
UPDATE: I found that myxperia was administrator even if I didn't turn it on, so I remove from administrators, but....same problem
Maybe it's better to try to unlock bootloader again following official Sony instructions, not flashtool? WITH flashtool unlocking, you haven't got a factory reset, that's the reason of all your problems IMHO.
After unlocking my xperia must disappear.

SONY thinks MyXperia is a useful feature security wise and I agree. It is just not for me since it prevents my tampering with the device.
I am sure it will be in MM.
You have to launch it explicitly on setup! SONY warns in the bootloader instructions to activate it after unlocking.
Once activated after unlocking the tablet is bricked. End of discussion, beaten to death in the xperia fora....
If a factory reset could revive the devices this would be no security feature but rather an annoyance for thieves.

I completely agree with what @DHGE said this is a no sense if a thief can reset the tablet with a factory reset once MyXperia has been activated. MyXepria operates at a low level, also be able to deactivate it easily is not possible.
:crying:
Oh my God.I haven't known it. http://fxpblog.co/2015/07/03/dont-destroy-your-unlocked-device.html poor people. Indeed, with unlocked bootloader and enabled myxperia, people get tea-tray instead of working device. And it's unrecoverable.
If nevertheless icon of my xperia will appear in a menu of new MM. Can I delete it with some kind of system-app-uninstaller ?
Edit 1. This damned app was in my system, so I used "Uninstall" app and remove my xperia, wiped dalvik and cash.
I strongly recommend it everybody to keep your device safe and don't worry incidental pressing.Better delete it!!!
I activated myxperia with unlockebootloader and I have no problem, can't be able to unactivate it, when I reflash the ro if activate it or not and I can remove administrator priviledge in security section.
If I clickif I want to turn it on and sony says that "if turned on"repair the firmware but will be "unusable" till you imput your google account saved for the my'm UNLOCKED I try turning on myxperia a few days ago to an disable it later (no ways, my xperia has only a blank page without settings), then I reflashed 2 times and both time it asked me if I to turn on the myxperia.I even try with flashtools to chek the bootloader, relock and reunlock and everything wly problem is flashing things via fastboot!
