Check your warrant terms. Most probably if the dead pixel is not a result of rooting/installing 3rd party software then your warranty is valid for this issue.

I've been issued a fault code from phones4u for exchange I havent really changed anything barring rooting it, The only thing is when you switch it on when its unlocked there is an unlocked padlock icon on the spalsh screen
Do you think they'll check/ be bothered?

Download Titanium, remove superuser, then "fastboot oem lock"
I think that should work, then just factory reset to top it off

fastboot oem lock will lock the bootloader back and remove the padlock from the splash screen.

brilliant, they've given me a fault code from head office so shouldn't be something I shouldnt be able to blag

Ok so I did a factory reset and locked to bootloader and went to phones4u you...
all were willing to exchange it.
1 was closing.
1 didnt have any
1 had one and had been opened as a show phone so I refused it
and the final one had 3... all opened..
Why do they feel the need to open all the boxes ?

Finally got it exchanged this morning for a brand spanker.
Unlocked, Rooted

[Q] I unlocked the bootloader. Is it safe to leave it unlocked?

Now when my Nexus boots - I see a lock sign (which is in fact unlocked lock) at the bottom of the screen.
What are the consequences to leave it unlocked? Somebody can hack into my phone? Data erase by accident?
Thanks!
Well in case of warranty troubles when the service power on the phone and the first thing they see is that the bootloader is unlocked you may be denied warranty.

Thanks! (that's a good argument to lock it)
And besides warranty?

Well, nothing. With an unlocked boot loader, you can root your phone and have fun with it. If something goes wrong you can always relock. Not like its hard. Your phone is technically easier to hack, but only by you. The idea of rooting is that you can have software that isn't approved, but most is completely harmless

There's no reason to lock it again.

[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.

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

insurance and rooted device

My nexus 7 is unlocked and rooted etc. I have insurance on it in case of screen damage. If I did drop it and it was damaged would insurance still cover it even though its rooted? I wouldn't see why not but thought I would check.

Normally the disclaimer said "Warranty is void if you unlock your device", but it's only in case of the problem is caused by the fact of unlocking/rooting the device. In fact they just cover their back ^^.
Your OS cannot break physically your screen (Fortunately ^^). Some people got their devices replaced on custom ROMed devices by Asus. If you want to RMA your device, if your device still running a bit, and to be sure, factory reset and relock your bootloader before sending it.
Sincerely
Cheers, can I unroot and relock all via windows? As in, if the device couldn't be used at all?

Yes, you can unroot and relock bootloader all via Windows. You just restore with factory image, and type in fastboot
Code:
fastboot oem lock
If the device is unusable, i mean nothing showing on the screen, i think Asus will not search for unlocking.
A long time ago, i was playing with my San Diego, and bricked it (When i tried to play with the locked bootloader and flash some suckastuff from me) and they accepted it on RMA, fortunately ^^

Remove 'bootloader unlocked!' text?

Hi guys. I want to remove this warning message when i boot up my phone. Can anyone help me? Thanks!
being able to do this would be great! I tried all the fastboot commands that work on different devices to re-lock the bootloader, flashed the bootloaders again...downgrade to Android 5, uncheck enable EOM unlock in the developer options..tried fastboot commands.. all was in vain...
Any other ideas?

I don't want to relock my bootloader. My goal is just removing this message. Because if the bootloop issue happen to me, sellers will not know that i've unlocked my bootloader. So they will repair my phone for free.
please can any mod close this? Has already been asked and answered. it's not possible! Do a damn search before!
there is not mention of this as far as I sow it anyways...
If you have it then post the link here so we can see it also .
PS: under the same logic we would not try to find a root or bootloader unlock and talk about it because its not currently possible.

If your in the EU and phone is still under warranty, LG will repair defected devices regardless if BL is unlocked as its a known defect. Read this thread.

I read about a guy saying something like changing the I-M-E-I (dont want to get banned or something) to something else, reboot and then restore it, you should have a relocked bootloader..
it sounds a bit shady but maybe this can actually work...depending on how this unlock is done.

Galaxy A50 locked by the network operator

Hi all,
So my father bought about a year ago his galaxy a50 in a new sealed box from unknown reseller, and recently the phone got locked by the network operator due to unpaid tax invoice for this device. It seems like the guy purchased it and only paid the first rate, and then resold it to my father for a full price. The phone when turned on displays a huge notification on the lock screen menu and does not allow me to do anything. Tried hard reset, didnt help. Anyway, I also tried to flash a linearge os on that, but it threw an error because the OEM unlocking option is not ticked (However, I managed to unlock bootloader before the device went down).
And my question is, is there any way i can flash any custom rom to get rid of the blockade without unlocking OEM? or should i throw the device away?
Thanks for any feedback !

The hard way easier said than done :
0. Factory reset your phone
1. Find a smashed A50 cheap
2. Replace motherboard (open up adhesive with heat gun)
3. Put your motherboard into the smashed one
4. Sell the reassembled smashed one on eBay for parts only
5. Profit
yeah.. actually I dont have enough experience to do it myself, I guess I'll just sell it as it is
Can you reflash stock ROM on Odin as an final desperate attempt of re enable unlock bootloader?
(Won't elaborate here, don't have time, you may search)

So it does not even boot now?
It still can boot, but when i set it up with the minimum permissions (no google account , no wifi. anything) the blockade still comes up straight away

Yeah, even after hard reset - It is supposedly caused by the software called Samsung Knox.
