[Q] Relock bootloader - warranty - Xperia Z Q&A, Help & Troubleshooting

If I received unlock code from Sony, unlocked phone via official way, than relocked bootloader and restored TA is there any way that service will detect if bootloader is relocked?

I think sony is only able to see especially if your request code!! but the operator does not see it because he lacks experience lool he does not know the word bootloader!
why this issue ??

I dont't think so, because you can request the code and never use it. Restoring TA brings the phone back to state like it was never unlocked. Nobody can tell if you unlocked bootloader or not. If you relock bootloader via flashtool instead via restoring TA backup, then they can tell you relocked it because your DRM keys will be missing. You are safe.

But if I did these steps:
1 Relock bootloader via flashtool
2 Repair via PC Companion
3 Install root and restore TA Partition
4 Install official firmware from here: http://forum.xda-developers.com/xperia-z/general/stock-xperia-z-c6603-10-5-0-230-central-t2759584
Is there ANY chance they will detect it?

No is the simple answer.
I don't know if they have the tools to check such things, but they most probably will only check if official fw == 1 &if bootloader lcoked == 1.
I normal language: They will only check if you have official fw and if your bootloader is locked.

ok

is it normal that the "TA backup" is 160 kilobytes? i did a backup sometime ago.. but 160kb is not really much.. i thought it would be 800mb or something

There is no flash counter to worry about with Sony phones...... Once you have unlocked bootloader your warranty is void even if you relock it.
Rooting does not void warranty.

Why?? I will relock bootloader, restore DRM keys, flash stock rom and will have same system when was when I bought the phone.
That I have "order" unlocking bootloader key doesen't mean that I did it.

Yes. But when you relock it, restore TA partition and flash stock there will be no sign that you have done it.
You may be correct... but most people will say that unlocking bootloader well void the warranty.

Yes, but you have given the imei of your device to Sony in order to get the unlock code. So if something happens to you phone and you get it at a Sony repairing center, the first thing they do is to read the imei from your device and check if it is in there database

And so?? They also have my phone in database when I bought it. I dont understand your reasoning.
I have buy a bulb yesterday. Just in case. Thats mean that I have to immediately change it??
No.
And for confirmation.
I ave do it twice.
First with my old LG GT540. (Stock -> root -> cyanogenmod (warranty off) -> flash stock without recovery, and fastboot (warranty on)
Second. Xperia SP (Stock -> root -> bootloader unlock (warranty off) -> existenz -> relocking BL -> Restoring TA -> Stock ROM (warranty on)
Both of them was rapairing without aditional costs.

Unlocking the bootloader, TA backup and the warranty

Hi,
i want to unlock my bootloader, so i made a backup with Devshafts TA Backup v9.10. The backup is a 112kb big zip file and 2mb big, when i uncompress it, i made a dry run to test it, everything seems ok.
To unlock my bootloader i must send my IMEI nr. to Sony.
My Question is, do they notice that i unlocked my XSP, even after relocking it with the TA Backup, by my IMEI nr that they have?
That would mean my warranty is voided even if i relock it?
Or am i wrong at some point?
Thank you for your help!
Well you lost your warranty if you Unlock your bootloader but I've never heard or read somewere that Sony (or the repair places) are using some kind of Database to check which IMEI has been used to get an Unlock Code.
If you relock the bootloader and restore the TA partition there is no evidence of any unlock.

No Backup of the TA partition?
Well thats not smart. Why is no one reading the tutorials?
First lines of the tutorial from Doomlord:
this is the official way to unlock bootloader
if you want to keep ur DRM keys, first root device and then check this out
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. INTERNAL SDCARD will BE WIPED!!!
For Xperia™ devices released 2013 or later (for example Xperia™ Z and Xperia™ ZL), the SD card of your device will be formatted and you will lose all content (for example photos, music, videos) when you unlock the boot loader.
DRM keys WILL be lost forever

older Xperia devices sometimes got issues after unlock of bootloader (BRICK after FOTA update) - you have been warned

Absolutely ... NO. Your device will be hard-bricked if you try to restore TA backup took from another one.

Some [Q] about Bootloader Unlock [Xperia T]

So I want to unlock my phone Bootloader and install a fresh AOSP 4.4
Mine current android version is 4.3 Jellybean ( 9.2.A.1.199) and on the sony bootloader unlock site when I insert the dial number it says "Root status ...... Allowed "
I rooted it today ( havent installed recovery buy I can do it later)
My questions :
Can my phone brick while trying to unlock the bootloader?
Do I need to download the latest version or the 4.1 version of android ?
All this I'm doing 'cus my 1 year warrantly has ended today so Why not ? :good:
Don't think the bootloader unlock procedure has much risk of bricking your phone... especially if you use the official Sony Bootloader Unlock method. But you may want to read up on backing up your TA before unlocking the bootloader.

I'd also suggest backing up your TA first. It's all in here: http://forum.xda-developers.com/showthread.php?t=2292598
If you unlock your bootloader, you lose your Bravia Engine. You can get it back when you lock bootloader, but only if you restore your TA. If you don't have this backup, BE is most likely lost forever.

I've done backing up my TA keys ( done the dry restore to make sure )
So Now I only need to unlock my bootloader ?
Still one question :
Can I use my current version of android 4.3
EDIT : Unlocked the bootloader , put rom , gapps , wipped WORKING AS A CHARM
Thanks for the help !
And if I would like to restore to stock do I need to relock the bootloader ?

Nice!
If you want to get your phone back to stock, just flash a stock FTF. Flashtool does not require the bootloader to be relocked for that.
Unless you mean "stock" for warranty purposes, or selling the phone... then I guess I'd say yes to relocking the bootloader, after flashing a stock FTF (and also restoring the TA, of course)
Thanks 4 The Info )))

warranty and bootloader status

hi, my z1 has a broken vibration motor. My phone is in warranty so i want to send it to repair. my bootloader is unlocked but i can re-lock it and i also have ta partition saved.

I'd give u a tip bro
Back up your current TA too with BL unlocked and save it in your pc, then restore your ta which is made before the first time u unlock bl, then flash a stock ftf and u go to sony.
When u get your phone back, get restore your ta from unlocked bootloader again, then u immediately have your phone unlocked again

u may unlock it yourself again, it will work as u expect but this way of unlock wipe your data and would take a bit more time
using the ta trick wont wipe it and it just takes 2 second, u dont have to type the unlock code bla bla bla

Is your bootloader unlocked? Is your phone C6902? Why in the world would you want to flash antiquated 4.2.2, especially if your bootloader is unlocked. The unlocking guide specifically states you have to be at least on 4.3 in order not to lose camera. If your phone is C6902 and you flashed C6903, you have a wrong baseband.
No. You can't use another phone's TA backup, unless you want to brick your phone.

I am not familiar with SOL23, but if your bootloader is locked, there is no permanent damage. You just need to re-flash the original firmware for SOL23. Try to repair it with Sony flashtool...
You have to restore your phone to original, then, if you want to unlock bootloader, do a TA backup, so that you can restore DRM function in case you would want to relock. If you unlock without backing up, you will lose your DRM key forever...
