[Q] Back to stock

I unlocked, root, flashed rom FXP cm9 on my xperia s. When my phone is damaged and i want to sent it over for repair how i go back to stock?
What are the steps?
I'v been reading and is step 1 relock bootloader with relock ftf (http://forum.xda-developers.com/show....php?t=1527159)
and then step 2 flashmode original ftf file enough? I don't have to unroot? Then everything is back to original? Without the drm keys ofcourse .

You lost your warranty when you unlocked your bootloader...

Yes i know. I just wanna know if these are the right steps.

you MAY void your warranty
this's not automatic. they are saying you that what you will do now with roms, kernels, recoveries aren't any more their business
if you flash galaxy ace kernel it's a problem of yours
but for example, a warranty claim about the yellow tint of the screen, (i think so) it's going to be accepted
my advice is to relock bootloader, and then flash stock rom (via flashtool)

I don't know how good relocking the bootloader works, so I won't make any promises about that. But about your question about unrooting, flashing the stock (unrooted) ftf is all you have to do. Those are as far as I know the only steps you have to take to get your phone back to as stock as possible.
Having your bootloader unlocked doesn't guarantee that your warranty is voided, so as long as it's a hardware failure you should be OK. Bricking is next to impossible so, software failure shouldn't be that much of a risk.

Thanks everyone for the info.

[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.

Stuck at Boot. S-ON.

@4m8 since you are the only guy here who knows best about HTC Desire 300.
Well my friend gave his Desire 300 to me for repair. i thought its going to be easy as like 1,2,3. but guess i was wrong.
I tried several options already.
USB DEBUGGING might be off as well since my friend doesnt know about flashing or unlocking bootloaders. i cant unlock the bootloader i think.
Its S-ON. (Dont know what it actually means).
I tried going to recovery but it shows me a PHONE with A RED ''DOWNLOAD MODE ARROW'' i think recovery is corrupted?
i tried already flashing boot.img and recovery.img over FASTBOOT. but it says ''failed remote signature verify fail''. its just isnt like my sony device which says OKAY all the time lol. those two files were found on a Google drive website.
i have no other options left to revive this phone.
Help will be a very good option :good: thanks in advance.
Well i read a lot of sites which says stuck at boot. and i cant find a Official Stock firmware for this device. is it that HTC didnt released one?

That sounds really bad. So let's recap to see if I understand your situation correctly:
Phone doesn't boot, can't enter recovery and will only load the bootloader. (b-loader status is S-ON Locked)
Now unless you are able to unlock the bootloader (which you aren't as you have stated) there is no way to flash a custom recovery.
The locked bootloader will prevent it because it requires anything you want to flash to be signed by HTC.
The only way out is to flash an actual official update by HTC which afaik is not available for this device.
To make matters worse, if the phone is branded you couldn't even revive it this way because some providers, like mine, actually force HTC
to prevent those phones from flashing an official HTC update that is not branded.
But there is a bright side to your situation. Since you weren't able to unlock the bootloader your friends warenty should still be intact.
And even if this was a branded phone try to claim a replacement from the manufacturer, that way you might have the chance to get
an unbranded device in return for the trouble you and your friend had to endure. :fingers-crossed:
Sorry if I had to shatter the last piece of hope that you were clinging on to but without an unlocked bootloader the only option that
remains is getting a replacement or begging HTC to release an update or the version that is installed by default as a RUU exe
PS:
Just to be certain, you did try the factory reset option in the bootloader before giving up, right?

Yes i did. Factory reset. But still no luck.
Yes, i cant enter recovery as well.
Well it actually started ones it told me "Process System Not Responding". And on that point i knew the system files are corrupted.
My friend told me, he left the phone in deep sleep after that it didnt turned on again.
Thanks for your help @4m8 :laugh: :good: (IT ISNT MINE SO I DONT HAVE A PROBLEM) I will give this phone back to my friend.
*FACEPALM TO HTC FOR NOT RELEASING A OFFICIAL FIRMWARE*

ASUS's Stance on Warranties

I unlocked my bootloader several months ago, but now my SIM card readers (both of them) have gone out. I have no idea how, no water damage or anything like that has happened. They just stopped working. So I went complete stock firmware, locked bootloader, everything but I am still unable to take OTA updates like a new phone would be able to. I think this is because they banned my device from OTAs which I believe they do if you have messed with the device. I need to RMA my device so my question is would it be better to say that I didn't tamper with the device and run the risk of them finding out I did, which is pretty likely seeing as how my device has been banned from OTA updates, or tell them that I did unlock it and all of that but that I have relocked it and I am back to stock? If any of you have had a similar issue how did ASUS handle that? Thanks!

How to you relock bootloader?

Since I am a new user I cannot post links. But Google "Zenfone 2 bootloader unlock" and I followed the instructions of Grekky's Blog.

there is no such thing as relocking the bootloader. only thing you can do it flash the stock image to make it look stock (since an unlocked bootloader has a white splash screen) but im sure asus knows of this and will still check and see that the bootloader is indeed unlocked and not warranty it.
This is just something we all accepted as a consequence of unlocking our bootloaders. hell i have a screen thats getting worse and worse with a yellow/brownish line coming from the top of the phone, but alas i have an unlocked phone too.

You can replace the white splash screen by flashing a black splash screen image to try and cover up unlocking your bootloader. http://forum.xda-developers.com/zenfone2/themes-apps/551-black-white-splashscreen-twrp-flash-t3141945 . If the reseller has no clue about custom recoveries and trying to flash a rom you'll be safe.

They fixed it, no questions asked. And yes, I was able to relock the bootloader.

Bricked for 8 months

Ever since Feb of this year my Realme X2 has never been fix, there's no solution for the Boot Image has been destroyed. So I had no choice but two just keep it on my cabinet for months now. I can't bring it to a repair center of Realme since this was bought in China. So I have up in the idea that this will never be fix and I just wasted money for that phone.

Did you unlock the bootloader? have you tried holding all 3 buttons ? (power vol - vol +) if you've unlocked bootloader phone will reboot into bootloader but you have a short time to flash a recovery and bring your phone back to life. if nothing works then the only thing you can do is sending the phone back to china for recovery.

See if the below video might help you un-brick your device.

Unfortunately I relocked my bootloader so that explains the problem, I can't boot into recovery nor in fastboot. So I lost hope on this already.
