Hi guys!
I need a little help: I want to go back to stock ROM and delete TWRP from my Huawei P8 (so I could get my phone repared by Huawei ).
Could you lend me a hand, little help and tell me the easiest way to do it? Links are fine also as long as I can trust them and wont brick my P8.
Thank you very much.
There could be a problem with this - they'll have your bootloader unlock request on record & the only way they are likely to miss it is because of an oversight (probably unlikely). Also, as far as I know, unrooting & relocking the bootloader does not hide the fact that it was previously unlocked.
If they deem the fault is not bootloader-unlock related & if your particular fault is covered under the warranty, you could be fine (but it's their decision to make) - from the terms of the Unlocking Agreement:
"Huawei will record your unlock request information; for software and hardware failures arising as a result of unlocking the bootloader, Huawei repair centers can provide repair services charged at the standard rate for repair work outside the scope of the warranty...."
So, be prepared to pay if they deem your fault is bootloader-unlock related, & would also recommend you ask in advance what the minimum repair costs are likely to be if your phone's fault is not covered under the warranty.
---------------------
If you'd still like to go ahead reverting to stock ROM, etc start by telling us what is your present ROM version? In other words, the full build number most likely in this format or similar: GRA-xxxxCxxxBxxx
Yeah, depending on your build, you can go to Huawei's sites support section, downloads, type in the p8 and find the stock firmware.

This has been discussed in other threads -- The problem here, however is that you still have to unlock the bootloader, so you are no longer left with a "stock" N1 and warranty is voided.
The easier 'equivalent' method is just to unlock the bootloader, install the custom recovery menu and then install the Modaco rooted 2.2. update.zip.
people keep saying this but warrantly is NOT voided.. you cannot void the warranty for s/w changes.. if there is a hardware issue htc has said and has honored their warranty.. now if you get the phone all fubared because of some software issue and cannot figure out how to recover or reinstall kernal, radio etc. then yes they may not cover it.
lgkahn, what do you base your statement on? Documentation clearly states that unlocking the bootloader will void your warranty. Once warranty is voided, it is really up to HTC to decide if they want to honour your no longer existing hardware warranty or not. There are people here that have successfully negotiated hardware repairs even after unlocking the bootloaders, but others who have not been able to if, I understand things correctly.
If you have any solid contrary information, please let us know. Thank you
Not to mention one of the latest posts is a guy trying to clean out the dust from behind his screen because HTC will not honor his warranty.
not true at all if you read the dust issue post it is because he knows he will bet another refurb if he warranties it.. not because they will not honor it.
gotta love spam

There has been a lot of discussion here of people who had their warrantied devices returned to them untouched because their bootloader was unlocked. Not all the time, but it may happen if you do that. The guide above is misleading because it does mention that your device will no longer remain stock.
Closing this thread as the original poster has already posted this in another thread... no need to start a brand new one.

*CAUTION ADVISED*
Individuals have reported fastboot problems impacting their devices after attempting an official unlock. Review thread and proceed at your own risk.
----------
Official unlock!
Just noticed this on the official Asus site under 'Utilities':
Unlock Device App: Unlock boot loader
Notice:
1. Update your software image to V2.20.40.59 or latest version
2. Before you download, install, and use the Unlock Device App you acknowledge and assume complete risk to the quality and performance of this App, including but not limited to the following: once you activate the App you will not be able to recover your ASUS product (“Original Product”) back to original locked conditions; the Original Product with the activated App will not be deemed the Original Product; the Revised Product will no longer be covered under the warranty of the Original Product; the software of Revised Product will no longer be deemed the software of the Original Product and can no longer receive ASUS software updates; your purchased digital content may also be affected.
You also acknowledge ASUS does not guarantee service satisfaction to any Revised Product, including events involving paid service requested by you to be performed to the Revised Product.
Furthermore, such repaired Revised Product will not be covered under the warranty of the Original Product; the software of the repaired Revised Product will not be deemed the software of the Original Product and will not receive ASUS software updates.
It is strongly advised that you avoid activating this App unless you fully understand and accept the risks that may arise.https://www.asus.com/us/support/Down...Ulh0Ph49Hl/32/
Update: Date stamp on the APK of 7/23/2015 is interesting. Ran on my unlocked ZE551ML and after accepting the terms of use, it complained that my model was not supported.
Oh crap nice find... Now if I use this I cannot or can do ota updates?
Worked here perfectly fine! Thanks!! Make sure you are on a stock ROM when you try
this is a great step!! thank you!!!
i checked: there is also for ZE550ML !!!
It's announced now
Khanger posted the announcement on reddit about an hour ago in /r/zenfone2/
Took 7 months but it's finally here haha.
Is there a difference between the official unlock and the previously known method of unofficial unlock? Unlocked bootloader is the same either way, correct?
Reddit thread says you will not get OTA after using this file.

Would like to know this as well.
Sad it does only concern 551ml version.
A, Does this unlock automatically give root?
B, And lets say I use this BUT I remain with stock, will I still be barred from OTA?
550 - direct download (source page, look under "Utilities"), mirror: mega

A) why would it? Root access and unlocking bootloader are completely different things.
B) if you unlock via official method, your warranty is void and your phone is barred from receiving OTAs.
I understand it voids the warranty but what I don't understand is why no updates? If you take an OTA and it hoses your out of warranty phone its on you.
hope someone discover relock method

From the official unlock, there likely will never be a way to relock and get back OTA functionality. That being said, adb sideloading OTA files should still work. Reasoning as such:
* Unlocking your device using the official APK sends a notification to ASUS that your device is now unlocked, out of warranty, and will not have OTAs pushed to it.
* Whether or not you can manually grab OTAs using the system app has yet to be seen, as we haven't received a new update since the official bootloader unlock method has been released. Personally, I believe our SSIDs will be blocked from getting anything from the OTA server based on the verbage in the disclaimer.
* adb sideloading a ZIP file should have no reliance on the bootloader status. As long as you're flashing the right file, it should work because adb sideload has no internet functionality so it can't call home to check on your ability to flash things. It would be a very poor decision to actively bar users who do the unlock from using official firmware updates on their own terms.
Anyways, I'm adventurous so I've taken the plunge of my own accord. I don't plan to put TWRP on or flash CM12.1 until the majority of the CM bugs have been resolved. When the next OTA comes out, I'll post my experience in obtaining and flashing it so that others can know if they want to unlock the bootloader officially as well.
I will comment specifically that Motorola bootloader unlocks did not bar their users from getting official OTAs after the fact. It is an assumed risk to unlock the bootloader and it's a bit salty to basically say "well, you did this, you don't deserve to automatically get what we're baking for you now". The fact that we got an official unlock at all is scores above what most other manufacturers have done, though. Hopefully, ASUS backs off of the no-OTA thing at some point as it is a bit unnecessary. At worst case, I'm trusting us all here at XDA to work your magic if we end up in a corner somehow.
my question is: if their unlocking method brick my phone???? warranty is expired and they don't take him ???
this method is a weird thing.

Attempting to unlock your phone is the same this as actually unlocking your phone: you're taking it's life in your hands. If you brick it trying to unlock it, it's not covered. If something happens to it after it's been unlocked, it's not covered. This does not necessarily mean that they won't repair it, it means that:
a) any repairs cost money out of pocket and
b) they have the right to say a device is unrepairable and send it back to you with no obligation to fix it or compensate you in any way.
Them's the breaks for being a tinkerer!

yeah, i think there are no phones with unlocked bootloader and warranty ok..
the only way is relock bootloader..no news for that now..
you said it is not possible..are you sure? i think unlock bootloader is an offline method?
Accidently lost my back up and no of no other means than to ask here. I'd appreciate it if someone would provide it to me as i cant seem to find it. SM975L Straightalk.

If you can't seem to find it, it may be because you weren't looking hard enough. Anyway, here is a link to your firmware.
It doesn't work when I try to install it through Odin. I need S975luduaof4 version. Sadly, I can't find it anywhere
You need to be a little more specific. Saying "it doesn't work through Odin" is not helpful as it provides absolutely no information. In retrospect however, this may be irrelevant. This is a Straight Talk S4, and the firmware is locked down about as much as an AT&T S4, with no real option to upgrade except by using a custom ROM.
Straight Talk won't have a copy of the firmware since their terms of service specifically prohibit unlocking, reflashing tampering or altering of the device in conflict with Straight Talk's unlocking policy. The warranty becomes instantly null and void if the device is so altered, thus no reason to keep a copy of the ROM. Unfortunately, there aren't many alternatives open to you now. You can't take it back to WalMart for exchange and Straight Talk won't touch it with a ten-foot pole.
So what exactly happened to render your phone non-functional?
I know that a while back this was true. But today I saw a few answers on here saying that ZTE was reviewing their terms related to the warranty, something about voiding the software warranty but not the hardware one.
Anyone knows where we stand regarding to that? On the same note, what about just rooting the phone without unlocking the bootloader?
The official answer from ZTE is that unlocking the bootloader invalidates the entire warranty. Only the US/NA model had the ability to unlock the bootloader, and it was only available on B20 when filling out the Google Docs request form.
Everything else is just speculation. Apparently, people on the Nougat beta seemed to say that the update would have the ability built into the base software load, but it appears to be not true for the official release. Other people (myself included) seemed to think that ZTE was just waiting for the Nougat release to put out the new unlock method, but that appears to not be the case. Everything thinks they should just invalidate the SW part and now the HW part, because that is what makes sense, but that's not the current situation.
I haven't seen any reports of people that unofficially unlocked and then sent their phones back to see if it got covered under warranty (as in, did they check the bootloader status).
Hopefully ZTE does something about this soon.

I know of at least one (but probably more) who borked their modem using signed twrp efs backup and sent it in for replacement.
Honestly I do not think warranty should cover user error/abuse but I suppose I would do it as well if it happened to me.
Weather or not they will honor warranty would depend on the issue and if it is obviously unlocked (custom rom/xposed/root clearly visible). If you relock/stock before sending it in they could not tell.
Is there any official word on whether the warranty will be honored after we unlock the bootloader and root the device or not? From what I could gather, this is the case for most Mi devices but is there any confirmation that the A1 will follow the same as well? I couldn't find anything specific to this device so I'd appreciate it if someone could clear this out for me.
Thank you!

Basically, in my country (Slovakia) and I believe that it's in every country (or at least should be):
If, for example, dead pixels appears on the screen after some time, root procedure or unlocking bootloader has 0 chance of making them dead, so the seller has to prove that the root process made those pixels dead, which is nonsense obviously.
They can deny the warranty if you try to do something with the system itself and you hard brick your device, that's the direct outcome of you trying to play with the phone's software.
Remember, system can be easily unrooted and bootloader can be easily re-locked with no sign of doing such things (not like KNOX), so if you are really afraid of them denying your warranty, you can unroot and re-lock just before the warranty process.
New to the device, planning to root my device. Will MI honor the warranty after root if I flash stock rom before taking it to the service center ?
Yes

I soft bricked my device and it was rooting always into TWRP. Went to the miA1 service centre and told them the truth ( even if I didn't, they could see TWRP). All they asked for is proof of purchase and had to wait my turn for them to flash stock ROM (I couldn't do that as my PC is being win XP)
Free of cost. No questions asked. Thank you Xiaomi
So my understanding is that they do it and there was obviously no need for me to ask for official policy
(Since OP is in the same city as me, it was the service centre close to Navrang theatre)

Yours being a software problem, they flashed the stock rom even though you had unlocked it. Would they repair the device if it is a hardware problem?
