[Q] Re-enable sim lock? - Galaxy Note II Q&A, Help & Troubleshooting

I got a sim-locked GT N-7100.
On the one hand I want to be able to - at least temporarily - use it on another network.
But I was told by my provider that once I unlock the phone (which I am allowed to), I would loose my warranty.
So: Can I re-enabled a sim-lock (without anyone noticing it was temporarily enabled)?
If so, please tell me how!
I understand just flashing a stock firmware does not affect the sim-lock setting.
There are instructions how to un-lock (see here: http://forum.xda-developers.com/showthread.php?t=2014982)
but not to re-lock
Thanx!

Where are you from?
I'm pretty sure Europe and US providers have no right to remove a warranty for that.
You can flash a stock rom if you need to claim under the warranty and reset the flash counter.
Even a proper network unlock (with a network unlock code that you have to pay for) removes your warranty?

I'm from Austria.
According to this: http://www.answers.com/topic/sim-lock#Austria it should be legal. Was even told by a nice guy from my operator I could do it, just that I would loose warranty.
I know about flash counter resets, so if I choose to try a custom rom (my note is completely stock until now) I'll be sure to use triangle-away before flashing a stock rom
Don't have the need for root currently though.
I dont know about details of warranty when it comes to unlocking.
I don't get why I it would void warranty since doing unlocking is someting thats even supported by the stock rom (just try a different sim and you get a screen asking you to enter an unlock pin).
Anyway, i'm still curious if it is possible to re-lock a previously un-locked android phone!

I got feedback on another thread:
slotguy:
I used the same thread to unlock then reversed it and relocked the sim. I don't believe there is a way anyone could tell it had been toggled off and back on. It is a service menu on the Samsung device.
So I tried the instructions, unfortunetely the lock control menu is not avilable with my firmware.
So am I correct that the only way is to flash an older firmware (4.1.1) and try with that?

[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!

[Q] Does flashing 'universal' (unlocked) stock ROM void my warranty?

Hey guys,
I'm sorry if this has been asked before - I did a search around but found nothing, surprisingly. Question is, if I flash my HTC One X (which is currently stock and on a plan with Vodafone, so full of 'bloatware' and 'outdated' builds) with the 'universal' (unlocked?) stock ROM will my original warranty be voided? My main reasons for wanting to do this is remove a few unnecessary apps that Vodafone include and make sure I'm receiving the latest OTA updates straight from HTC. Obviously I can continue to wait for the updates and turn a blind eye to the 'crapware', but if I'm able to flash the official stock ROM straight from HTC then I'd much rather do that, just need to make sure no warranty issues will arise as I'd hate to have such a beautiful device collecting dust because I was too impatient or ignorant to check beforehand.
Thanks for any suggestions or help,
DJ GLiTCH

If you are going to flash any ROM (including stock) you will need to unlock your bootloader first (via HTC dev) and install CWM Recovery. The act of unlocking you bootloader voids your warranty. They keep a note of all of the phones that they have unlocked. You may still be covered for physical defects (although maybe not) and you definitely won't be covered for anything software related.

Not technically true.
HTC clearly state that unlocking your bootloader *may* void *certain* parts of your warranty. In other words if you screw up your phone as a result of flashing roms then your on your own. If your phone develops a fault then it's covered.
HTC can't possibly keep a note of what phones have been unlocked. How can they? When you go through HTCDev.com you get sent the unlock file which you then have to flash. Only because HTC sent you this file it does not mean that you have flashed it - you may have changed your mind afterwards.
Once you unlock your bootloader and flash a custom rom you can choose you revert back to Stock by relocking then flashing the Vodafone branded RUU file. Providing you don't balls up your phone during this process your entire warranty will remain intact, including software issues.

If you unlock and afterwards relock the bootloader again, in fastboot mode it says bootloader RELOCKED and not LOCKED. That`s how they see it.
I spoke to Vodafone Australia and they assured me that the act of unlocking alone does NOT void your warranty, however once you make a modification, warranty is gone. So yes, flashing another Rom will void warranty

Actually, as pointed out by Gee2012 above, the bootloader says Relocked if you lock it again - so it is fairly obvious. This is irrelevant anyway as they have your phone imei number which is most probably what they use - they aren't stupid!
And from what I have been reading - HTC are being funny when people are trying to claim on warranty even if it is a physical defect that you have, once you have unlocked your bootloader. See here:

Yes I know it says relocked but HTC arnt keeping a "note" as such at the point of unlocking via HTCDev.
I sent my HOX back due to dust under the screen with the bootloader relocked and I received it back good as new (still unlocked).

They gave your phone back due to a hardware issue - fair enough. But if you went back for example with poor signal quality, even if you have flashed your original RUU, I very much doubt they would consider that under warranty anymore. They know you have unlocked the bootloader and tinkered with the software (even tho you are now back on stock). Have a lock at the link that i posted - it seems to be pretty murky water!
I also think that it also varies from servicecenter to servicecenter how they cope with this procedure or protocol. Some are more strict than others. I once took a bricked I9000 (due to a bad flash) to Dynafix and they repaired it under warranty!
It was running a custom rom and kerrnel.
Thank you all very much for your responses. I'm sorry for the delay, but for some reason never received any email notifications of replies.
I understand that flashing 'may' void warranty, depending on how far you go with the whole unlocking the bootloader and custom roms, but my concern is with flashing a non-carrier orientated stock rom. Such that I can revive updates quickly and OTA without needing the delay of Vodafone and the like, as well as removing all of their 'useful apps' they include inside their roms which I cannot remove.
Not trying to go off topic here either, but I come from a Samsung background (upgraded from the original Galaxy S) and was just wondering if the flashing process is similar? Like I'm guessing there is no odin for HTC, but clockwork mod and the rest are still around, correct? Not after instructions, just curious, as I'm trying to avoid losing my warranty and would likely only flash stock roms (for the time being at least, until I cave in). Cheers.
According to Vodafone, you will lose your warranty regardless of what you flash whether its stock based or not. They also said that simply rooting voids it as well.
However you might be able to flash the stock RUU for voda which may cover your tracks. I'm not 100% though.
As for flashing, Im still stock at the moment but from what I gather it is the same with respect to clockworkmod recovery and what not. But just double check any OPs before you start though lol

Upgrading from .42 to .62

I have a UK Xperia Play on .42 firmware with CWM recovery and root provided by Zerg Rush.
I've heard that I need .62 to install some of the custom firmwares.
.42 appears to be the latest firmware I can get OTA. I'm not sure the best way to upgrade to .62, do I need to go via .58 or similar.
Does it matter that I have a UK phone?
Is it possible to preserve my settings?
Will I need to re-root at any time?
In the long run I am looking to install DooMKerneL and probably something like Jokawild.
You have to flash the ftf file for your phone
Here is a link to 99% of them
http://forum.xda-developers.com/showthread.php?t=1589399
If you install a new firmwares. Maybe you'll need to root it again..
But since the devs makes the pre-rooted custom ROMs, you don't need to root it anymore

I don't have an unlocked bootloader. Is this required to install a custom ROM even if I have root?
Is there any disadvantage to unlocking the bootloader?

No unlocked bootloader = no custom kernels/ very limited to roms
Only disadvantage is it voids your warranty, but being that you have root, you have no warranty anyway lol
I was in the same position as you. I wanted to get a custom ROM and be able to overclock my phone. After a few annoying errors, I finally got it up and running
Basically, your going to have get your phone into flashmode and then flash the .62.ftf file on your phone. Congratualtions you now have .62FW (although youve lost root).
To get root on .62 FW, your going to have to flash a custom kernel (I did DoomKernel v14). To flash a kernel, your going to have to unlock your bootloader. After unlocking and flashing the kernal, your phone is now rooted.
And plus the positive side Ive heard is that you CANNOT brick your sony eircsson phone. (well you probably could but there is a very very slim chance of that happening).
Thanks.
It seems I can't unlock via the regular Sony way as Unlock Bootloader is set to no.
I think I need S1Tool or something similar (maybe something I have to pay for) to get my bootloader unlocked. I'll check the forums a bit before I ask any questions that haven't been asked before
i did it via omnius and it work great, i just payed 19.76 for one single unlock credit on gsmserver
not sure why people say that root voids warranty.
i have ATT play 4g and it was having hardware issues, so i flashed the stock ATT software back and took it to the store. i got a "new" one in the mail two days ago.
I also sent my rooted xperia play that had the slider broken to CLARO El Salvador and they repaired it (They flashed their ROM again XD)
Now i have unlocked bootloader but who cares i have premium insurance
Any modification to the software voids the warranty..
Update:
I downloaded s1tool and connected the test point to the ground. Everything seems to have worked so I am guessing my bootloader is unlocked. Is there anyway I can verify this, or should I just attempt to install a kernel?

Try to put the phone in flash mode (green light) if it recognizes it, it's unlocked. I think there is a sequence or symbols/numbers you can do to check it, but idk what that is since im a r800x
To check your unlocked bootloader you need to dial: *#*#7378423#*#* , then go under, Service info > Configuration > Bootloader unlock allowed: Yes/No.

[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.

If I lock the bootloader is the warranty still ruined?

I am planning to root my device and I was wondering is the warranty still ruined after locking the bootloader so my question is:
If I lock the bootloader is the warranty still ruined?
Well you don't lose it in the first place. No, unlocking the bootloader doesn't void your warranty.
if you restore MIUI rom and bring back phone to factory system you not loose your warranty, only if you leave unlocked bootloader and custom rom in phone you dont have warrant.
I believe once you unlock bootlaoder service center can check if you did it or not even if you re-lock it.

No, if you reflash the firmware, they can't check if you've unlocked it before (if you didn't unlocked officially in the first place).
Well most manufacturers (cheepo ones) do not implemented this kind of tech that persists data over a firmware flash.
Also, most of the time, they don't even check for this.
