Can I unlock my bootloader again after replacement of motherboard? - G4 Q&A, Help & Troubleshooting

My phone bricked one day, got completely unresponsive and didn't give any signs of life. It had unlocked bootloader.
I gave it to repair and got motherboard replacement.
My IMEI number is the same as before, but there bootloader is obviously locked now.
What can I do to unlock the bootloader now?
I don't want to have my phone bricked again so prefer to ask before doing anything as of yet.
Thanks.

Yes u can

"Re-Locking" bootloader question.

Ok so my handset has the screen flicker issue. I ofc want to return it to see if I can get a handset without the issue, however I unlocked the bootloader. I realise this voids my warranty but with my old Desire I could pretty much return it to stock. With the new unlocking system when you relock the phone it literally says "RELOCKED" at the top of the bootloader screen. Does anyone know of a way to restore the bootloader so that it will read "LOCKED".
I realise this is my own fault but I cannot help but feel cheated if the phone has an issue that I didn't cause and now I cannot return it. It is on t-mobile if that helps anyones suggestions.

Since Screen flickering is a hardware problem, you should be fine with warranty, because warranty is only void if software is causing a problem.
You can relock bootloader with fastboot command: fastboot oem lock
But its not like the real HTC Lock.
I hope that helped.

[Q] Bootloader Re-locked. Warranty?

Hello there,
since 4.0.4 wasn't coming to my phone, I've flashed the stock image from google on my GNexus. I was wondering if, having unlocked and re-locked the bootloader, my warranty is void, or if it is back on.
Thanks in advance
Doesn't rooting already void ur warranty?

As long as you put stock from and relock bootloader, no one can tell you've done anything to your phone or voided your warranty.
Just like an iPhone jailbreaking voids your warranty until you restore it back to official firmware.

You can always return to stock and lock the bootloader. No one will be able to tell you've done anything to the phone at that point.
I send my SGN in for repair after reflashing the stock image and relocking the bootloader. And there were no complaints that my warranty is void. So I asume there is no flash counter like on the SGS2.
Alright! Great to hear
Thanks a lot for all the replies =)
Oh, that's great to hear!
I have a similar question...If you were to be lazy and not relock the bootloader, would the people at a local VZW really know? I mean, in the past, I have seen people take rooted and Rom'd HTC phones to sprint and easily gotten replacements.

They probably wouldn't know... but how the hell lazy are you? Connect the phone to a PC and type "fastboot oem lock" into the command window. There's absolutely no reason not to lock the bootloader before sending it back in.

if they have 1/2 a brain, yes they can tell the bootloader is unlocked... since there's a picture of a unlocked lock.
As I wrote before I send my phone in for repair and relocked it before. Today I got my phone back and when I turned it on it was unlocked. I think they don't care about unlocked bootloaders as long as the issue is not caused by onlocking the bootloader.
They should be able to tell whether ur bootloader is locked. It changes one of the codes. For my w8 it changes Rxxxxxx (locked) to rxxxxxx( unlocked) so as long as they check ur warranty is as good as dead

Why bother even relocking it, if you need to unlock it again you'll have to wipe your internal storage.

[Q] How to relock bootloader to 'locked' not 'relocked'

Hi guys, i have a question, i want to return my phone for warranty and i've read this thread that if your bootloader is showing 'relocked' you cannot return the device for warranty.
I am here to ask if there is a way to make the bootloader show 'locked' bootloader instead of 'relocked'?
it would be GREATLY appreciated if you could help me. thanks!
for those who want to relock their bootloader can follow the instructions here
There is no way to do that ATM.
If the problem is the hardware issue, HTC should honor the warranty.

actually i'm looking to sell the phone, the phone have no issues whatsoever, but if the person i sell to wants to claim warranty, it may be an issue.
Not possible. When you got your unlock bin from HTC, it logged the device info. There gonna know right away it was tampered with.

so that means there is no option to claim warranty unless i pay for the 'fines' or charges that incur to repair my device?

Correct. From what I've read, unlocking voids the warranty instantly (even tho htcdev says it "could" void your warranty) So any repairs are gonna cost you.

kfasheldon said:
OK.. while trying to re-flash my phone after messing up, I tried to re-lock (fastboot oem lock) and it put up 3 messages, 1 succeed, 2 failed, on reboot of phone it read locked.
Yes!! Locked not re-locked ! I forgot I had not flashed stock recovery ! So triued to unlock, it worked but I could not flash stock recovery, failed, but I could re-lock with same LOCKED message, if I then went from HBoot to Fastboot I got a new menu SECURITY .. bellow locked a message SECURITY WARNING, if I select SECURITY menu then I get a new screen , KEYCARD failed, and reboots.
Anyway the LOCKED was enough to get the phone swapped as its two weeks old, any way after charging and attempting RUU again it locked on black HTC screen most times it booted.
Still maybe this menu holds a key to S-OFF, and maybe the relock failing can be replicated, it seems to have sent only 1 of 3 parts if the file across, so if you phone is bricked maybe you can give it a shot for htc service cover by part re-locking in some way.

and was hoping we could make some headway on it.
I noticed you are on Vodafone Australia.
I spoke to multiple stores and service reps and each of them said the same thing, that merely unlocking the bootloader will not void your warranty with them assuming a hardware fault. They even allowing discussion of bootloader unlocking in their community forum.
They did say however that flashing custom roms and rooting will void your warranty as per usual and any damage caused as a result of overclocking or messing with voltages etc is not covered.
I don't know if that is any help, but they seem pretty good about it so long as you didnt cause any actual damage yourself

Unfortunately I bought it outright from All phones. Don't think they'll accept it. but never mind anymore, I sold my HTC one x. I put up a *phone has boot loader unlocked* note on the ad

[Q] tried to unlock my boot loader with ez-unlock, now my Galaxy S3 won't turn on

I installed EZ-Unlock 1.2 on my phone then proceeded to unlock the bootloader.. everything worked fine.. said it worked.. so I restarted my phone and it did not restart.. the phone will not turn on at all.. no hard reset.. no download mode.. nothing.. when I connect it to my pc it doesn't do the usual connect sound now its 3 short ding sounds (bassier sound)
any help would be appreciated..
thanks in advance
The bootloader should already be unlocked on the gs3 except Verizon. No need for this tool. You might have a brick.

I forgot to mention that the phone does nothing... No Let's even when plugged into a charger... Even if it was bricked shouldn't it do something.. Could the battery have died?
QHSUSB_DLOAD when connected to computer
No, if it's bricked its just that. A brick. It does the exact same thing as a brick. Nothing. You need jtag repair to have a functioning device again.
Considering it is hard bricked will my service provider Honour the warranty?

That would be considered warranty fraud. You need to pay someone for jtag service to revive your phone
No. You voided your warranty when you tried to unlock the unlocked bootloader.

I just did the exact same thing! Will a JTAG bring it back to proper working order, the same way as it was before, or should I just buy a new phone?

Yes JTAG will work fine or at least should. I haven't seen a case yet that JTAG didn't work

Provided there is no hardware damage, jtag will fix a brick that was caused by software incompatibility.
Any other way
Is there any other way besides JTAG because I don't want to spend money to repair this. I hard bricked my s3 after trying EZ-unlock on 4.4.2 my screen won't even turn on.
thats because the S3 comes with unlocked bootloader. look thru the debrick thread and might find a method there. good luck.
here you go..

[Q] Getting Htc one x ready for warranty

Hey guys!
Ok, here's the case, I'm having troubles with my HOX, probably it's lcd or motherboard, the phone's screen won't wake up most of the time, and you can feel vibration while touching the screen which means it's working and you just can't see it.
I'm preparing the phone to send it back to warranty, flashing back the stock recovery, relocking the bootloader and flashing original firmware (downloading as we speak). The thing is, I'm quite worried the warranty will be void due the re-locked status in the bootloader and I'm wondering is it possible to get it to say locked again or is it possible to somehow intentionally brick the phone so they can't even get to see it was rooted and unlocked?
Any suggestion will be highly appriciated

I don't think it's possible to make it appear locked again. But when my HOX died I just handed it back in.
Nothing helpful but just sharing my experience.

My colleague had problem with screen - with wake up. And when service saw relocked they told that it's related to the unlocked bootlader and installation of other software.... Warranty not void....

I've had numberous e-mails with HTC staff via htc.com and they told me that they warranty is NOT void by unlocking the bootloader or flashing a custom rom. it IS void if you do something wrong and brick the device.
Although, If I were you i'd still return to stock.
