Hi there is it possible to relock the boot loader for xperia mini? I unlocked it because i tried CM7. Now I am thinking of going bag to original firmware. Any help is appreciated!
If relocating is not possible, what should one do to get as close as possible back to the original firmware, is it still possible to get official upgrades?
Best,
Thorsten

Third, remember if you are doing it with official method, you will never able to receive FOTA or SEUS update, you can, but only by flashing from xda.
So since we did the unofficial method, After we update through SEUS the bootloader is still unlocked?
I don't know about that. Since the service info still says bootloader unlocking allowed, I think the phone thinks itself as still locked. Flashing from seus might rely more on drm instead of whether the bootloader as locked or not.

when service info says Bootloader unlock allowed: true, that means that it the bootloader is locked, but can be unlocked at will
as many devs say, unlocking the bootloader voids the warranty and bricks the phone when doing FOTA or SEUS
but there's a flashtool out there for us that will take care of it

You do know this method right? http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/ When using that method, it is unlocked but the report still says 'Bootloader unlock allowed: true'. So if you use this method (as what idareyou and me were doing back then) the phone thinks that it is still 'locked', even though it's unlocked.

Yeah. I can confirm that my bootloader is unlocked but it still says 'Bootloader unlock allowed:Yes'
I thought at first I wasn't succesful even though it went smoothly so I tried flashing custom Kernel and it was succesful.
I want to know if in the future if SE release their ICS and we update using SEUS the unlocked bootloader remains because believe me, I don't want to go through the same process again, I got electrecuted several time because I don't have test points, just a clip and copper wire.

Veimus from original thread confirm that seus do works and he can reflash the gingerbread from seus. Sm gt should be ok with ics, And with Sony confirms mo changes hm kernel. I think it will be Rom update only.

Hi everyone, i 'm going to be concise. I own an HTC onex+ international version (it should be no brand) and i would like to unroot it and reset to factory for a warranty issue. I'm extremely noob so i would like, if it's possibile, the fastest, easyest and safest way to do so.
On internet i found several guides about it as http://onexroot.com/one-x-unroot/how-to-unroot-rooted-htc-one-x/ or http://theunlockr.com/2012/12/28/how-to-unroot-the-htc-one-x-2/ BUT i found also an xda tool http://forum.xda-developers.com/showthread.php?t=1870652&nocache=1 that sounds appropriate to me; i read on other forum that i need some kind of extra instrument like boot.img
There are some things to take note of. The boot.img and HBoot image flashing requires users to get their own files as those are device specific and aren’t included

actually i have no idea where get it and how use it. I would be very gratefull if some of you could explain to me step by step how to do the unroot.
ps. i just rooted and put inside the cmw under the instruction of friend of mine but i don't really understand how i did it.
thank you in advance.
relock bootloader and install RUU and you are back on Stock
but would you be back on stock for a warranty issue, you didn't must do that.
warranty has nothing to do with your firmware or root or bootloader unlock.
they would be erase all at your phone and flash the RUU

thank you for your reply but the problem is that actually i don't know how to relock booloader and what RUU is; that's why i was lokking for a step by step guide. I may follow and understand a little the guide of before but i'm not safe that it works with htc onec+ too.
but would you be back on stock for a warranty issue, you didn't must do that.

really? i belived that an "unlocked" phone was an enough reason to invalidate the warranty isn't it?

if you dont touch the bootloader it says: LOCKED
if you unlocked bootloader it says: UNLOCKED
if you relocked bootloader it says: RELOCKED
we can never go back to LOCKED (RELOCKED is technical the same like LOCKED, but it shows as RELOCKED) all people can see that the bootloader was touched by the user
so it cant the reason for that
to relock:
boot into bootloader
and execute this command in fastboot:
fastboot oem lock
now you can install your latest RUU (RUU is the Stock Firmware from HTC as *.exe to install from Windows [depends on your CID])
Hello,
is it possible to relock bootloader after ulocking it? I need it due to the warranty.
in short, No. please search the forum for details, as this is discussed.
i suggest you just try the luck sending the phone in and not mention anythong about the bootloader. of course should flash to stock rom if that still can be done

Why you want the warranty? Want to sell it later? Or did it already got any fault?

I think, he did not say he is sending to service center. He just said he needs it for warranty (in future).
See how smart these new pals are. May be we are all idiots to unlock it without giving a second thought. lolz
I do not have yet any fault, I just want to try alternative rom and I want to have way back to stock rom
My last phone had after 3 month of use some problem and I must return it. So I just want to know if it is possible
I thought that flashing the stock u-boot & x-boot will re-lock the bootloader.

Maybe this should be in a sticky post somewhere. I have seen a few people ask about re-locking the bootloader.
If this works, we should start collecting u-boot & x-boot images.
There is no way to relock bootloader. Here is good post about bootloader and omap4430, it applies to L9s. In our case ics xloader ,uboot or both simply don't recognize that bootloader had been unlocked and it just appears locked.
I see. Thanks you.
So, you guys with unlocked bootloader, have no problem with fact that your devices have no warranty?
If you don't mention the unlocked bootloader to the customer service and your device has an unrooted stock ROM, there is only a few chance that they check the bootloader if it is for an hardware issue.
It only requires a little bit luck .
If i will make root by this:
http://forum.xda-developers.com/showthread.php?t=2173465
With locked bootloader, then install cwm. May I then install cyanogenmod and if something goes wrong may i return to original stock rom together with warranty?

cwm requires unlocked bootloader
I think you need to install the "CWM Recovery" bootloader to flash a custom ROM. And with a locked bootloader, you can only have a bootloader signed by LG (not a "CWM Recovery" one).
However, you can try this : http://forum.xda-developers.com/showthread.php?t=2095825
It is a "CWM Recovery" which is not directly placed inside the bootloader (instead, it adds a step on Android start). When I tried it on my P760 (when it still had a locked bootloader), it failed (but you can still try).

Actually that recovery will not work on jb,
Ok, that's why it failed for me.
Now, you have your answer, you must stay on ICS if you wish to keep your bootloader locked with CWM Recovery.
However, I would be curious to know what happens if a JB ROM (custom or stock) is installed through using this "locked bootloader CWM Recovery".

I received "Security Error" when attempting to boot when I tried this a while back. It just won't work because the kernel needs to be signed by LG.
So may I at least root phone or even root is not possible without unlocked bootloader?

Root is possible with boolloader, try this method (it worked fine for me while I wasn't on an unlocked bootloader) :

So, if I unlock my bootloader and my phone gets bricked and needs service, will I be able to use my warranty? If not, is there a way I can make the phone look like it has not been modified in any way(ex: maybe lock the bootloader again or something like that) so that I can use my warranty?
Thanks in advance.

You can simply flash firmware via miflash. Everything will be like brand new, bootloader will get relocked.

relock with MIUI 10 Global Beta installed?
@smokin901 @AkkiV
-When unlocking, does the hard reset occur? (factory reset, or reset data)
No, unlike unlocking HTC, Motorola ... unlocking occurs without loss of data but if the data on the phone is encrypted, you must first disable the encryption, otherwise the data will be lost. Then unblock and you can turn on encryption again. Exceptions are Mi6, Mi Note 3, Mi Mix 2, Mi Mix 2s. They have a complete discharge. And it looks like this trend applies to all fresh models.

Does this apply after relocking?
It is better to opt for encryption since in Mi devices unlock won't erase my personal data...?

For example Mi 8 Chinese Ver. if you want to relocking bootloader from Chinese Vers. you have to flash Chinese ROM, if you flash Global ROM in Chinese Ver. device, you may brick your device.

You can claim warranty with bootloader unlocked, TWRP installed, rooted and with custom ROM. Water damage will result in no warranty.

AFAIK, warranty for Xiaomi devices remains intact even if you unlock the bootloader.
Obviously you can lick your Bootloader if YOU'RE ON THE STOCK ROM.
You can flash the stock rom with fastboot and select
Clean flash and lock
And your Bootloader will be locked.

Why do you want to lock? It is better to remain unlocked once you have unlocked. In the event of you deciding to flash a custom ROM, you have to unlock again and your data partition will be wiped.

Dirty flash your stock ROM through the Mi Flash Tool. There is an option to lock the bootloader.
