I want to unlock my bootloader to get root access but i want to know is there a way to relock it again if i want to sell it or if something go wrong and get back my warranty ? ( sorry for my bad english )
You can make a TA-backup before unlocking, restoring that will lock the bootloader.
However, if your phone breaks in a way where the PC won't be able to recognize it, you won't be able to restore the backup.
Hello!
I have N5 from the first batch. GPS is like ***, recently even worse, problems with microphone etc. I've decided to return the phone. However, my problem is that the phone was bought in USA while I stay in EU. So I have to prepare the phone perfectly before I send it to my friend who will deal with returning it to google.
List of sins: unlocked bootloader, CM a lot, now upgraded to Android 5.0 (using factory images from google). Till the update the device was not modified. However, I'm little bit scared, because bootloader seems to be unlocked.
Is my warranty void? Or can simply I return the phone with bootloader unlocked? If no, please help - is there a step-by-step guide on how to completly return to stock including locking bootloader? Returning to 4.4.4. is ok, I'm sending the phone back to USA anyway
I'll be extremly greateful for help.
Br,
Piecho
Just flash back to stock relock bootloader.
You need the nexus 5 toolkit .
Sent from my Nexus 5 using xda premium
Reflash stock rom then return it as it is. Google does not care about have the bootloader unlocked or not.
Don't use any toolkit learn the proper commands and do it manually. The Google factory images page gives you step by step instructions. Like said before, Google doesn't care about unlocked boot loader. The factory images page even tells you to unlock, flash, then relock lol
Just got the D6633 dual Sim for my wife. I use Nexus devices exclusively but since Sony offers bootloader unlocking I decided to get this phone instead of a Nexus for her.
My question is, should I go through the steps to actually get the bootloader unlock code for future use. I don't plan on unlocking the bootloader just yet but I worry that in the future the service might be discontinued and I'll never get a code from Sony.
It's still under warranty and I'd like to keep it that way so I guess the real question is, is getting the code what voids the warranty or actually preforming the unlock that does it? Is there a counter or some type of a flag in the device that is set permanently or can the bootloader be locked back again like any Nexus device?
Thanks for your help.
No, it's not like KNOX [SAMSUNG] or S-ON [HTC]
Keep the code if you want.
That is one of the reasons I prefer SONY devices, besides the specs and build quality. No stuff like tripping KNOX fuse or getting S-OFF to make an HTC a Google Play Edition for example.
Keep the code, just in case.

OK, but if there is no tripped flag, how do they know I didn't use the code? I guess you didn't understand my initial question. I can understands the code doesn't expire, but doesn't the act of getting the code voids warranty?

You trigger something on their servers, it's all about the IMEI and Serial Number.
Even if you relock the bootloader, they will still know it was unlocked, I for example relocked the bootloader the official way, via SONY website, and got the code in my email.
Not quite. Warrenty is coded when you unlock the boot, nor when you ask for the code.
You can get the code and keep it forever.
Officially there is no way to re lock the bootloader anyway.
However, if you root first, backup the TA patition them unlock the boot, you can restore the TA partition to re lock and don't will not know.

True, it is a good idea to backup the TA partion, I myself didn't do it, but it is a good advice.
OK, so I'm gathering that there is a way to root and install recovery without unlocking the bootloader. If that's the case, why would anyone need to open the bootloader?
Also, I'm still not clear on my initial question. Do I loose warranty as soon as I get the unlock code from Sony or does the act of unlocking what voids it.

Only when you unlock you lose warranty. But you can backup the TA partition, and relock later, if you want.
With an unlock bootloader you can root Lollipop easy, with a lock bootloader, there are a few steps, like downgrading, for example.
And many more stuff you can do, with an unlocked bootloader, flash custom ROM's...mods, tweaks, etc.

So if you can lock it back and need to claim warranty they won't know you ever had it unlocked? Something seems not right.

If you restore your TA partition, yeah, you can claim warranty.
Hello everyone,
I'm here cause I'm going from a z3 Bl unlocked, custorm ROM and other to an z5 bl unlocked cause gived by a sony employee who repair phone.
But he give me it with an unlocked bootloader, then I don't have the DRM.
I don't want to make some bad things like with my z3 who have some freeze, reboot or other things.
The z5 is in 6.0, is it possible to get back the DRM to get back fingerprints and all other stuff like photo treatment,.... ?
Also, there is a operator rom with just some apps installed that I desinstalled, is it going wrong with next maj or not?
Thanks for your answers
Edit: I think that this unallow me to cast with a chrome cast?
IF the previous owner backuped the TA partition/DRM keys before unlocking the bootloader, it's possible he still have these backups in his possession OR possible he restored the TA partition after installation a custom ROM, TWRP, rooting, etc.
If you can, open the dialer and type *#*#7378423#*#*, then go to "Services tests" -> "Security"
You should see two [Active] occurences, OTP_LOCK_STATUS: LOCKED / FIDO_KEYS: Provisioned
That means the DRM keys are active and that's what you want. If it's the case, I would strongly suggest you to temporarely downgrade the phone to an older Lollipop firmware and backup them in a safe place (thre's many guides on this forum)
Personally, I wouldn't buy a second-hand Z5 that doesn't have its DRM keys intact anymore, or at least a proper backup of these keys.
I thinks it's good I have this :
Marlin key ok active
Widevine key ok active
Ckb key ok active
Huk:...
Prodid_aid:0004
Otp lock config 0155
Otp lock status locked
Auth enable 07
Device id:...
Fido keys provisioned
Factory reset reason : not found
Then I have just to find a tuto who downgrade and backup drm?
Edit: I just pay a new screen cause he was broken and old owner give it to me ^^

Seems that all DRM keys are intact, you may follow these instructions to backup your TA partition :
http://forum.xda-developers.com/cros...-tool-t3349597
Try to flash stock firmware and perform wipe on it so you could test all are working normally.
Thanks redjge,
But after put a Sim card into the phone everythings seem okay
Is there still no rooting options for locked bootloader??
Any other phones have been hacked and got root capability...
No. Pretty sure all phones from the Z5 need to have the bootloader unlocked.
All 64-bit devices Xperia Z3+/Z4 and onwards all require an unlocked bootloader for root. The real question you should be asking is... Can we get a DRM backup? With a DRM backup we can unlock and relock the bootloader as and when we want. Without DRM keys backup we can't relock the bootloader from my understanding. Thats the closest we can get to locked bootloader root unfortunately.
hm... too bad..
Yeah don't want to unlock unless there is a way to get the DRM key backup.
Not risking my warranty just yet.
