Need to LOCK/UNROOT/FLASH for hardware repair? - Nexus S Q&A, Help & Troubleshooting

So I'm sending my NS into Samsung, 51 weeks into my warranty (yes that means less than 1 week left), because my power button stopped functioning.
Do I really need to flash it back to stock unrooted and locked bootloader? I can't imagine Samsung would be so bold as to claim void warranty via software when it's clearly a hardware issue. They would have to prove that my software stuff caused a hardware issue, which is impossible. The button doesnt work even in recovery or from an off position.
Just curious before I send it in. Thanks!

[Q] Has unrooting for warranty ever worked for anyone?

So I have a new Galaxy S3 I747 Bell Canada, and I'm thinking of rooting it, but I still have 11 months of warranty left. Now I know that I can just follow the complicated guides to 'unroot' it, if I need to send it back, but has that ever actually worked for anyone here?
Because think about it. If you need to send your phone back for warranty, it is probably broken, right? If your phone is broken, how can you possibly unroot it first? Sure there are some non-bricked reasons you could send your phone back, such as a broken camera or a small deadzone in the touchscreen, but I'm just worried that my phone will suffer a NAND flash breakdown (after that whole kefuffle in the news) or a malfunctioning CPU while in a rooted state.
But then I think, well if the NAND flash or CPU completely dies, will THEY even be able to tell if the phone is rooted? I mean sure they have tools where they can rip the flash out of the mobo and read it and see if it's rooted, but to do all that would cost them labour hours. I would imagine if I sent back a rooted phone with just a broken camera, they would turn on the phone and see the big "THIS PHONE IS ROOTED!!!" message and refuse my warranty, but if I can turn my phone on, I will unroot it before I send it in for a broken camera. But if the phone CANT turn on, would they really bother with all those low-level hardware tools to try and fix my phone and see if its rooted? Wouldn't they just send me a new phone, and possibly try and refurbish my broken one to resell, without ever noticing that its rooted?
Depends on what your issue. Most of the buttons on my D2 stopped working and I had to send it in for warranty. Had to sbf and wipe and then it was fine. VZ has additional "root counter" features, but as you aren't using their device the standard unroot procedures should be fine. I think they take care of the on-board root counter.
If your phone is completely unusable then you're just out back. Obviously you can't take care of what you need to do if the phone isn't functioning at all. That said, depending on the damage they might not even be able to check for root anyway, and they just might not care. Also depends on your carrier's policies.
Honestly i don't recomend rooting ur phone on the the warranty period

[Q] Wifi not working after repair

Hi all,
So I recently repaired the screen of my HOXL and ever since, my phone does not catch a wifi signal unless I'm standing like 1 feet from the router. I'm guessing that the repair guys made some screw-up while assembling/disassembling the phone. I'll be taking it up with them soon but was wondering if anyone could shed light on what might be wrong and if I can repair it by myself?
My guess is that the WiFi antenna is not properly connected when they reassembled the device. I wouldn't mess with it, as you may make matters worse, and therefore void any warranty or liability they have on the repair.
Warranty is already void since I rooted the device

I don't mean the manufacturer warranty, I mean the warranty or responsibility the repair service has on the work they did.

yellow tint on screen repair of an unlocked phone

I am going to send my unlocked rooted (but stock ROM) phone to Sony repair centre because of a yellow tinted spot on the screen.
The yellow spot is near the charger contact and a Internet search reveals this as a common problem with the glue turning yellow due to overheating.
However, my question is, would Sony accept my warranty claim with a unlocked bootloader. I will wipe the root and return the phone to stock before I send it, but i can not change the bootloader stat (DRM key).

This is Sony official stance on warranty and unlocking the bootloader. In practice this means that once you unlock the bootloader they no longer have to honour your warranty. If your screen discolourment is due to overheating (As you suggest) I suspect that Sony will claim a custom kernel with overclocking could have done this, hence they will not honour the warranty
Voiding the warranty
If you unlock the boot loader, you may void the warranty of your device and/or any warranty from your operator. See your device’s warranty statement for details. Additionally, due to the modified device software, Sony’s repair network will likely have to replace key components before it can properly test, repair and verify your device using our repair tools and software. Consequently, if Sony performs a warranty repair, Sony will likely charge you a significant service fee for the additional costs caused by your modification of the software.

I gave up having the yellow lines fixed, it's more to much pressure on the screens causing the issue. Had mine fixed honestly 7x

Random Screen Shut-Off

Hello Everyone, I am Extremely new to posting on XDA so I am not sure if there is a standard or not. Basically The Problem I am having is that the Screen randomly turns black and does not turn back on unless connected to the charger for about a minute. I know that the phone does not die as both the digitizer and speaker continue to function. I have Tried:
-Software Initialization in SmartSwitch
-Factory Reset in Settings
-Factory Reset through Recovery Menu
-Odin reset Image 5.1.1 and 6.0.1
I also can not turn it into the Samsung Service Center as I already replaced the back of the phone in attempt to reseat the lcd/digitizer cable. If Anyone has any experience or insight into this I would fully Appreciate it. Thank You.

Does your phone function 100% as designed (i.e. are you able to use your phone) while it is turned on or does your phone gets frozen?
Is your phone still under warranty? If your phone is still under warrant call or online chat with support and get a shipping label and send it for repairs. There is no need to inform the support about what happen to your phone before. If support determines that your warranty is void they will provide a quote to repair your phone. Also you can dispute the claim that your warranty is void. If you decide not to repair the phone they will ship it back to you for free. So you have nothing to lose but a lot to gain by send your phone for repairs under warrant.
I observe that many members post questions but seems to bee too busy don't care to provide an update in this forum once the issue is resolved. Hence kindly update us of your progress as it will expand our collective knowledge.
This seems to be a common problem and it a known main board defect. I have a similar issue and I have to send for repair after I return to the US from my vacation.

Okay so I retried updating it without a reset within smartswitch and so far it hasn't turned off. Also If I did want to Ship the Phone, Will they accept warranty if there is a small crack in the bottom right of the back glass. BTW Thanks you for the reply.

In my opinion that should not void warranty (not a water damage - you could always claim that you're phone fell).
As I said if the repairs are not covered under warranty they will give you a ridiculousness high quote to repair it out of warranty and you could decline and they will ship it back to you at no cost to you. So on the downside you have nothing to lose and you will get back your phone as is but on the upside you might get lucky and get it fixed for fee

Update(June 21, 2016)- Samsung Gave a Free Label For UPS 2nd Day Air A.M. The service center they are shipping it to is only about 15 minutes away, but I am just going to utilize the label.

Ok so they had my phone since Friday, but said they received it Monday. I found out today that the back glass did cause it to not be in warranty. Fortunately, they have already sent it back to me and it should be back tomorrow. Hopefully they tried some software trick and it fixed it. Fingers crossed!
Ok so They gave me a free box with some packaging(samsung). Looks like they didn't even touch the phone as it was not factory reset.

SquareTrade sent me a bricked phone?! HELP!

Hey all,
I'm admittedly not into the whole rooting scene, so I know very little about it... bear with me.
I have a Galaxy S6 with water damage to the screen, so I used my SquareTrade warranty to receive a replacement device. Just turned it on this morning and set it up, no problem - synced my Google account, re-installed my apps, etc. Then it popped up a message that Samsung had a major firmware update and that it needed to restart to complete the process, so I clicked restart and install.
Phone restarts, and doesn't come back on. Top left of the screen it says something about "Custom binary blocked by FRP Lock". I Googled this and found stuff coming up about rooting phones, but obviously that's not what I was even trying to do. Someone said if you try a hard reboot it can fix the issue, so I did that, but when I hard rebooted it a message came up warning me about the dangers of installing firmware from third parties and whatnot, but that I could proceed if I knew it was safe, so I did that. I also noticed in the top left of this screen it said "Knox Counter: 1 x 00500"
At this point it tells me it's installing and to not reboot the phone, but a half hour goes by with no progress. I Google the Knox counter thing and stuff comes up about rooting and voided warranties. I call Squaretrade, and speak to a specialist with broken English and try to explain. He says he'll send a replacement to me (and they can't guarantee that it will be a black S6 which I'm bummed about). I make it clear that I was not the one who "jailbroke" the phone because my concern is that Squaretrade will turn the device on, see the message and assume I did it and charge me the $750 replacement fee, believing me to have voided the warranty. He assured me that he made a note of it on the claim and that I shouldn't be charged... but I'm still worried about it.
Worst case scenario just in case something goes wrong and they try to charge me, I'd love to know what y'all think might have happened here. Do you think the previous owner of this phone (since the replacements are refurbished) tripped the Knox counter? Why did it work the first time I turned it on but then crash after I tried to install a firmware update? And when I receive the next replacement, how can I make sure this doesn't happen again?
Now I have TWO phones I'm on the line for sending back to SquareTrade (the original damaged phone and the replacement with the voided Knox counter) and I'm so paranoid that I'll get f**ked over somehow. Any input would be greatly appreciated!
