[Q] Rooting and carrier warranty

I need your help guys,
just got my Xperia ARC and i wanted to root it by this guide and i have a few questions:
i bought the phone from an Israeli carrier (pelephone if its matter) so in the guide i need to change the carrier firmware to the original firmware and i wander if it will void the warranty. also is there any way to change back the firmware after the change, if so then how? i searched and i couldn't find anything...
thanks ahead

The thing with Rooting a phone, is that you can root your phone and still the ¨stock¨ Arc is untouched after you have unrooted.
The flashing and rooting dont break the warranty by it self.
If you change from locked bootloader to unlocked.. The warranty is removed.
Easiest way to root is:
*Download*
3.0.A.2.181 Generic World: http://www.mediafire.com/?​y9s73andrl4bllc
*Use Flashtool to Flash .181*
Flashtool: http://www.multiupload.com​/7H4JT35B6G
*Use Gingerbreak after you flashed back*
http://forum.xda-developers.com/show....php?t=1044765
*After it have rebooted and active, go to settings and do a OTA over wireless.
This way you keep your Arc locked, nothing good comes from unlocking the bootloader yet.

That's not entirely true. You've got custom ROMs being developed; over-clock kernel just released, Recovery and what not.
Unlocking the bootloader is personal choice. I may not unlock my bootloader just yet but I can't deny that with improvements being shown, it's an increasingly tempting option. LOL!

Warranty after mod and unlock

hello
Can one return to stock rom/kernel and lock the phone so service center cant detect prior modifications?
Thx

Yes. What have you done to it so far?

I found one modified with a warranty still valid and im looking to buy it.
So im considering if i buy a faulty unit can I return it to stock and colect a warranty.
I now have Galaxy i5800 and i know i can make it to stock but i also have a xperia mini and i also know if i unlock boot locker warranty is invalid.
That was my dilema.
I personaly think this unit is sim unlocked, rooted, and custom rom and kernel is flashed (the whole 9 yards).

You can return the desire to stock from whichever condition you receive it. Hope this answers your question.

Installing an original RUU should reset everything to its original state.
If you've got a custom hboot, you will have to install the Bravo Downgrader hboot from alpharev first, afaik.
I've already heard of people who sent their rootet desire to repair because of a hardware defect and it was no problem - but I wouldn't bet on that .)

[Q]Unlocking bootloader, questions!

I'll make it short:
1. Since you have to provide your IMEI number on the sonymobile website, i guess that even if you relock your bootloader later, sony will know that you have already void your warranty and you will permanently lose your warranty. Is this correct?
2. Can "locked bootloader" roms be flashed on phone with unlock bootloader. I know it's a silly question but i didn't want to open a new thread for just one question
3. Any benefit of unlocking the bootloader over flashing roms with locked bootloader?
4. Is it worth playing with roms on this device at all, since jelly bean is just around the corner? I know that official firmware is always bad and that the custom ones are modified well. I'm fed up of the lag my phone has, every time i pull my notification bar...i'm on official firmware and i'm using build.prop tweaks but they're not helping much.

SONY Says unlocking Bootloader may void it's warranty.
Well see, this is how it works in my country. Upon unlocking bootloader i loose my warranty. But the warranty for any hardware damage is still valid here. Which means with a unlocked bootloader i will not get warranty if my phone gets bricked by any Custom ROM/MOD try out or Software related issue.
But let's say, the screen isn't working or the speaker isn't working, then i might get a replacement for this type of hardware damage. Only parts replacement.
But yes this may not same for all region. Or may be the SONY service center people here are little too kind
But yes, they can check the bootloader unlocking status easily, if i am not mistaken, cause one of the SONY Forum moderator told me so.
Lastly, Playing with the ROM actually Depends on you, some likes custom ROMS and some like Stock ROM.
But since the JB update is just doorstep ahead, so i would say, you wait for it. Do not unlock it now.

1. Yes they usually check but it depends on your country too. In my country I got my phone's screen replacement done within the warranty after unlocking my boot loader.
2. Yes you can flash any ROM for Xperia S.
3. Main advantage is that you can flash custom kernels ( even ROMs like Cm, slimbean etc.)
4. Absolutely. You can still enjoy official JB even after unlocking your boot loader.

Proper unlock request message reason

I've read that Xiaomi my reject your request for unlock of device. I've applied for the unlock two days ago but I really don't know where to check its status? And basically there shouldn't be any specific reason why one would want to unlock bootloader unless they're trying to install third party ROM? If one writes the reason as being I would like to install Xiaomi.eu ROM on my device that Xiaomi would strait off reject it or not? Because mainly that's what I would like to do until Xiaomi releases sources (if they do) at which point many will move to other ROMs (CM etc.). So.
Questions:
What kind of good reason may someone have to unloack bootloader so that unlock will be accepted without issues?
Where can one check unlock request status?
If one unlocks bootloader and then flashes official ROM (which will likely lock it again), can one unlock it without additional unlock requests to Xiaomi?

1. I said I bought from Gearbest and had a shop rom installed and want to install original rom (which was true, but nobody can confirm this obviously)
2. I do not think you can check it
3. Flashing official ROM will not lock your bootloader again
I would suggest you wait a little more and if you still do not get a reply, open a new request or post in the forums.
btw, the request completion will be sent via an SMS message, nothing else.

It worked like a charm, received the unlock code half an out later.

Unless you are flashing a fastboot rom with miflash and select the flash and lock radio button.

I wrote flash global rom. got the approval few hours later

I said "I want to install the xiaomi.eu rom for localization."
3 hours later they approved the request.

Thanks guys. I got permission to unlock after about 4 days. I suppose they had a bit more work after Black Friday so it took them a bit longer than usual.
But of all the reasons you're mentioned I think the best one is I'm an Android application developer. Others related to fake ROM etc. are not as viable as I'm pretty confident they know exactly which ROM you're using on which device the moment you sign in with you Mi account.

Bootloader Unlocking
If any problem, If i unlock the bootloader ???
In my redmi 4 ???
Plz tell me ...

Something Emotional and Real
I got permission in 4min by giving a emotional reason like my brother flashed wrong Nougat firmware on my Redmi Note 3 and my device got bricked I need to unlock bootloader to fix it.
And got permission.
Hurray

I've bought a Redmi Note 8 Pro and the devices is locked by Xiaomi

Hello there, I've bought this model.
There was a custom ROM flashed on it when I get it.
I've flashed it back by the Stock Firmware.
Then I saw that the device is locked by Xiaomi.
What can I do?
The best option would be to unlock it with the Stock Firmware on it, so I would have any other Option,.
If this isn't possible I would like to know how I can flash a custom ROM on it.
The bootloader is also locked, so please help me.
Bye, JonnyBoy84

Ask seller for unlock bootloader again (Official way) and remove his account from phone. (But I don't think he had, maybe he got the phone by unofficial way also)
Or you can use free unofficial tool to unlock it (Unofficial way, easy to find on YouTube).
Then choose one custom rom from forum.
