[Q] How can i do this without losing warranty?

Hi all,
in the next days i will get my HTC M8 (i'm moving from an iPhone 5s but i had the M7 and the One Mini too, both with boot loader unlocked and custom rom)
Since this will be my first HTC device "new" from store, i will get the warranty of 24 months and so i will try to preserve it.
What i want to do with it is:
-Root It
-Install ViperONE Rom (so a custom rom)
-Stop.
But how can i do this without losing warranty? Or rather, i want to do these things but with the possibility to bring the smartphone to 100% stock and of course removing the text line like "unlocked, tampered" etc. to preserve the warranty if i will need it (of course i hope i never need warranty).
How can i do this? Is ok also if you say me only what i have to do without tell all the steps, i will search by myself the guides.
(Sorry for my english but i'm italian)

Don't know about warranty T&Cs where you're at... But if you have S-OFF you can go back to stock as much as possible so that they don't know the difference.
You can try Firewater S-OFF but seeing as you're buying a new device it'll probably have the newest 4.4.3 on it which means that Firewater S-OFF won't work. Still worth it to give it a try if you want to though.
Better option, though it costs money, is to use Sunshine S-OFF, it'll both unlock the bootloader and give S-OFF, it costs $25 though.
You can then root, flash custom ROMs etc no problem. You can even flash custom ROMs if you're still S-ON, though you won't be able to remove the flags like "Tampered, unlocked/relocked" if you're S-OFF. Which is why I'd suggest getting S-OFF.
If you have it and you need warranty you can follow the guides provided on these forums to go back to 100% stock. With S-OFF you can remove the red text that you might get on start up screen. You can remove the tampered flag in bootloader. You can make the device say "Locked" instead of "Relocked" if you were to lock bootloader again. You can take it back to a state that it'll look(At least on the surface) as if it's 100% the way you bought it. Which should be more than good enough for warranty purposes.
So if that's the direction you're looking in i.e To customize and still make it look like you never tampered with device in the event of warranty, you'll definitely need S-OFF for your device.
Going by your post, I'm sure you'll search for these things then?
Sunshine S-OFF
How to return device to stock - It'll be the same to return to stock, just use correct nandroids for your device.
How to remove red text from Hboot

All of the "How to" threads you can find in the general section of the HTC One M8 forum. The Sunshine S-OFF thread you'll find in the "Paid Apps" forums on the main screen of xda forums or you can just search for it on google like "Sunshine S-OFF xda" it'll give you a link to it surely, the Author of the post is Jcase.
Edit: I added the links to the How to's and Sunshine S-OFF.

Wow your reply is simply amazing, thank you so much!
Just one little questions: if Firewater will work, how can i unlock boot loader without htcdev procedure?
Thanks again, is really great that XDA community has users like you!
(PS: don't know if this will change something but i'll have an M8 with Vodafone Brand (but sim unlocked) too!)

In the last link I provided "reset relocked flag" the actual title of the thread is [how to] lock/unlock your bootloader without htcdev(s-off required) .
On your PS. Just make sure you make nandroid back up of your device before flashing custom ROMs. I'm not sure if your Vodafone backup is in the collection thread or not. Of course you'll also then have to make a backup of your recovery before flashing a custom one.
You can just boot the custom recovery of your choice - fastboot boot name_of_custom_recovery.img - that'll boot in so that you can make a backup of the stock recovery before you flash it. That'll only work with Philz I think... TWRP didn't boot for me with the newest 4.4.3 software and it doesn't make a backup of the stock recovery anyways. Philz can do that though, or you can follow the instructions I gave in this post - Of course you'll also need to run the cat /proc/emmc command to just make sure on which block number your recovery partition is. You'll need root for that of course. You can flash supersu to gain root while booting a custom recovery so you don't have to flash one.
Though it'll also make things easier if you do decide to go with Sunshine because I'm sure they have a method in the thread to have root for your device also.
So that's important, getting a backup of your device BEFORE you do anything, in the event you want to go back and we don't have a backup for your device it might be a problem if you didn't make one yourself either :good:

Ok thanks for all the infos!
At this point, i think that Sunshine will be the method that i will use.
So now i have just to wait the shipping of my M8 and as soon as i get it i will FIRSTLY backup and after i will start modding! If i'll have problems i will ask to you/the community again. Thank you!

No problem.
Perhaps if you made a backup you can upload it and share the link in the COLLECTION of Stock backup's thread. That'll help even more people with similar device to your own :good:

Sure i will! I always helped (in others italian forums) developers with backup, test etc: i love modding and help developers!
So i'll just backup through TWRP right? Because i always used Clockworkmod

Yes you can backup through TWRP but like I mentioned, it didn't do backup of the recovery partition. So you'll probably have to use the method I linked to in order to make backup of stock recovery.
TWRP gave me some problems lately...not booting like it should, it didn't make backup of stock recovery. I like TWRP and prefer it but Philz definitely did the better job for backups. Could probably boot that up and make a backup of everything too if you prefer. Doesn't really make a difference, I mean, if(BIG IFFF) something happens to your device you could always just flash Philz back and restore the backup. It's easy enough so...

So will be better Philz

I used Sunshine right of the bat, so I could return to stock and keep my warranty. A good plan. ?

I will use it too
2 days and i will finally have my HTC M8!!!
I ordered it 7 days ago but the store had misspelled my city -.-
I will verify that he work at 100% (wifi, signal, display etc) and after i will start modding it

Guys yesterday the M8 has arrived!
After i tried all the basic functions (call, wifi etc) i started with sunshine!
After i upgraded the firmware, flashed philz, backuped ROM and installed ViperROM. Now i'm very satisfied of my new smartphone! Thank you all!

Bootloader Unlock Question

Ok, so I have recently switched to a HTC One M8 and I am puzzled by a few things regarding unlocking the bootloader and flashing ROMs. Coming from a Samsung Galaxy s4 I have never really needed to worry about unlocking my bootloader. I have looked up on the subject and have found that with unlocking the bootloader using HTCdev you have to flash boot.img everytime after flasing a ROM on the HTC One. Does this also apply to the HTC One m8 ? If so does anybody have a better means of unlocking the bootloader without needing to do this after every ROM flash.

You don't have to replace hboot unless you want to get rid of certain firmware messages, like the tampered flag. Unless you are sending your phone in for warranty work, you won't likely care about it, since you only see it in fastboot/hboot mode. The only thing the token does, besides unlock the boot loader, is remove certain preloaded apps, like the flashlight, which will screw up further OTA updates.
However, I would suggest you look into going S-off, as it makes locking/unlocking the boot loader possible without contacting HTC at all, and without messing up OTA updates. You also gain the freedom to change your CID (if you ever want to convert to stock Developer Edition), SIM unlock, and revert to older firmware if necessary (such as restoring an older RUU to go back to stock) However, S-off is "security off", so there is an increased chance of bricking the phone if you aren't careful.

Ok so what i understand is: To install a custom rom I first have to get s-off, then unlock bootloader, root and install custom recovery and I am good to go? Please help me if I have missed anything.
I am used to flashing a rom every week on my Samsung. This is why I am so worried that I might do something wrong.
Edit: I have also found this link: http://forum.xda-developers.com/showthread.php?t=2265618 please tell me if it is the correct way to do it.

Im going to use it this friday to root my phone.

Ok so if I understand correctly now...using that guide I will not need to use htcdev and it will not be neccesary for me to flash boot.img after every rom flash?

Not quite. To flash a custom ROM, all you need to do is unlock the bootloader, install custom recovery, and flash a ROM. In addition, I highly recommend you make a nandroid backup before flashing anything
S-off is only needed if you want to avoid the bootloader unlocking method via HTCDev.com (and HTC therefore having a record of you unlocking by IMEI); or to flash hboot, radio, firmware, or a few other things (such as SIM unlock). S-off is not needed to flash a ROM.
One caveat, if your phone presently has older firmware, you will experience some severe bugs on any Sense 2.x based ROM (long boot times, broken WiFi or Bluetooth) and having S-off is required to manually update the firmware. So, while in literal terms, S-off is not needed to flash a ROM. But if the above applies to you, you need s-off to manually update the firmware and get the ROM to work correctly. Alternately, you can OTA to the latest firmware before modding the phone. You will need to list your phone's hboot and present software version for us to tell you what firmware you are on.
Also, its not necessary to root before flashing a custom ROM. You will be rooted after you flash a custom ROM.

Definitely not correct. That guide is for the M7. Be careful what device forum section you are in, and stay in the M8 section.

Hell, I feel like a noob again. Ok so no boot.img flash after flashing a rom is needed.

Nope, not needed. Boot.img will flash automatically along with the ROM. Don't assume that anything on the M7 applies to the M8. These things change as the hardware changes, and every device has its own subtle differences.

Correct, no need to flash boot.img separately when flashing ROMs, if you unlock the bootloader via HTCDev.com (or by the S-off way).

How to root my HTC One M8 (Android 6.0)?

I would like to root my M8, it has the latest OTA update from HTC which is Android 6.0. I have the developer edition, from what I've heard, the bootloader is already unlocked right?
I've seen some guides but most of them are outdated or they are meant to be used with Android 4.4.4.
I must say I'm not an expert when talking about phones, so is there a step by step guide to root an M8 with marshmallow? I would really appreciate any help.

The bootloader screen will indicate the bootloader status (LOCKED, UNLOCKED or RELOCKED) near the top of the screen.
In general, the process is:
1) Unlock the bootloader by HTCDev.com (if its not already unlocked).
2) Fastboot flash TWRP 3.0 custom recovery: https://twrp.me/devices/htconem8gsm.html
3) Backup your stock ROM in TWRP - lots of folks have been running into bootloop or no boot after trying to root (but probably usually when trying to use an obsolete version TWRP and/or SuperSU - but it never hurts to be safe and have a backup).
4) In TWRP, flash SuperSU v2.76 to root: https://download.chainfire.eu/969/SuperSU/UPDATE-SuperSU-v2.76-20160630161323.zip

Thanks for the answer. Just one more question. My bootloader is already unlocked, but it says "S-ON" under "UNLOCKED", will that be a problem?

Nope, that is just fine. S-on is perfectly okay for most mods, such as root, and flashing ROMs.
You only need s-off to do some very specific things, such as flashing modified hboots, manually flashing radio, changing CID&MID, downgrading by RUU, etc.

I have a simple doubt regarding flashing twrp. Does this means I can flash twrp through adb without getting root access to get root access.I usually root my devices using kingroot,works perfect for my old phone micromax.It also works for my htc one m8 when it was kitkat.But after I update to marshmallow Kingroot doesn't work for it,tried many times.If you could answer my question I would be very thankfull

You don't need root to install TWRP, if that is what you mean. You just need an unlocked bootloader.

what carrier ? if you are on gsm just flash TWRP 3.0.2-0 from official website
https://twrp.me/devices/htconem8gsm.html
after you flash TWRP recovery you will find option to backup it's too easy to understand how it works ( just check the partitions you want to backup and confirm your choices by sweep to proceed the process )
after you make a backup flash the latest supersu.zip from here ( choose TWRP installable.zip )

I think you're looking at some really outdated info or guide. TWRP hasn't been carrier specific for about 2 years; with Verizon and Sprint being the only ones you had to look out for. But TWRP was unified long ago (so Sprint/Verizon no longer requires a different TWRP version). You'll see from ahmed's link, that it specifies "All variants" of the M8. The exception would be if you have an M8s; and maybe another oddball variant or two (which are really different hardware). But as long as its a true "M8" the TWRP version linked by ahmed will work.
If you have any doubts or concerns about the M8 version, connect the phone to your computer, reboot to fastboot mode and do command fastboot getvar all and post the results so we can take a look (delete IMEI and serial number before posting).

No, you can't flash SuperSU without first flashing TWRP. Why would threads/guides tell you to do something that isn't necessary, if you can just skip it?
Simply put, you can only flash official "signed" files from the stock recovery. You need a custom recovery like TWRP to flash SuperSU.
Hmz27 said:

Click to expand...
Click to collapse
Once you install TWRP, you can use it to create a backup of your stock unrooted ROM and user data. And its highly recommended to do so, before you flash SuperSU. Not only will this give you an easy way to revert/recover if something goes wrong with the root attempt; but you will also have a backup of your stock, unrooted ROM if you ever want it.
There are other ways to backup your data, but that depends on what "stuff" you are talking about (as that vague description doesn't tell us what you actually want to backup). For instance, for files, photos, etc. you can just copy and paste them to your computer as a backup.

Firewater was an all-in-one kit used to unlock bootloader and achieve s-off. The guys that created this went on to create Sunshine, leaving firewater project behind, so any guides from 2014 are likely obsolete. Unlocking the bootloader is as simple as going to htcdev.com, making an account and following the instructions there-it's super easy. S-off isn't necessary for most.

Firewater and the AIO (all-in-one) toolkit are 2 different things. Firewater is an (obsolete) s-off method. May have also contained a temp root, and some other things (can't remember exactly, it's been 2 years - and doesn't matter anyway - see more below). But firewater is not typically referred to as a "toolkit" or "all-in-one" (never seen it referred to that way, actually).
All-in-one toolkit (there are a couple) is a PC for unlocking the bootloader, root, and several other things (may have had a link for firewater, don't remember - again it's irrelevant for reasons below).
The toolkits are not recommended. They haven't been updated in a long time, and therefore use very obsolete files for TWRP and SuperSU (when applicable). You will have issues flashing many ROMs with old TWRP (and I'm surprised you haven't yet). Plus, you will probably find in bootloader and fastboot getvar, that the OS number is now blank (known bug in old versions of TWRP). I would suggest flashing the current version TWRP 3.1.1 using fastboot, to prevent issues moving forward. Current TWRP is fully compatible with current ROMs - but will not fix the bug of OS number being blank (need to flash firmware or RUU to fix that - but it's just a minor thing).
Firewater doesn't work, no matter what you do. It required an online server component, which the devs took offline over 2 years ago. Sunshine ($25 US) is the only current s-off method. But be aware, that most folks don't need s-off. S-off isn't needed to root, flash custom ROMs, and most other mods. s-off is only needed for very specific things, such as manually flashing radios, changing CID/MID, and some other things.

redpoint73 thank you so much for such a help truly gentleman much appreciate it .

It appears you can no longer use the usual method to unlock the bootloader. I just got this phone the other day in fantastic condition as a gift.
HTCDev told me there was an error or try again later. I'll upload screenshots later.

Not true... I used www.htcdev.com to unlock the bootloader of my HTC One M8 today.

I have this phone, with Android 6.0 and bootloader locked. However it has become practically unusable as it regularly powers off by itself, most likely due to lack of storage (there's only 0.6 GB left...). I've already uninstalled all of my few (useful) apps, I have no media on it whatsoever, but it is just filled up with bloatware that is pre-installed and gets re-installed automatically and that I thus cannot get rid of. I don't want to buy a new phone (it's in good condition) but from reading on the internet I understand that the only option is to unlock and root it, and put an oem on it exempt of all of these useless apps.
So my questions are, is this really the only option and if so is it still possible on this old machine to unlock the bootloader, and to get the right - clean - software for it somewhere?
I registered at HtC dev. There's a page that walks you through the unlocking process. So I should be able to do that part, if what FlexMcMurphy said in July last year still is true... For the rest, I'm quite new to this process but there are pages here on XDA that describe rooting and flashing. I'm ready to give it a try, but could use help if stuck.
Any reply/help would be wonderful !
Thank you in advance.

Verizon HTC 10 S Off help?

Hi, I need some help with decrypting my device so I can s off it. Im new to rooting and am unsure whether the videos on the unlocked 10 will work for me, and even then S Off brings up what is in my linked image. Should I proceed? What is this partition thing? Please help.
tfw cant post the ****ing screenshot, How do I show you guys the thing?

Upload your screenshot to imgur? www.imgur.com
I just used Sunshine to s-off mine. It was $25 for the license but it worked flawlessly and took no time. It was worth it to me just to remove all the Verizon apps, I haven't even touched any custom roms or kernels yet.

I think the only way to decrypt your device is a full factory reset -- that's what Verizon claims, anyway. http://www.verizonwireless.com/support/knowledge-base-204803/
I guess you need to S-OFF a Verizon variant before you can install TWRP? Not sure. Regardless, one way to do this is back up your system using TWRP, apply S-OFF via Sunshine, format data in TWRP, and then restore from your backup. Still, you might be able to backup with TWRP after S-OFF, then format data, then restore the backup.
If you're new to rooting, be extra careful with your phone after you S-OFF, because it becomes really easy to brick the device. I nearly ruined my HTC One M7 by applying the wrong firmware.

There's a Verizon specific section for the HTC 10 in which you would find your answers quickly.

M9 Stuck in a permanent boot loop even after hard reset :(

Hi everyone,
It would appear that my phone is stuck in a permanent boot loop. I'm still on the latest official rom from my carrier, it's not rooted nor have I made any changes to the bootloader.
The only thing that I did was restart my phone from within the OS after I couldn't launch the official SMS app (some MMS process error).
Now I'm stuck in a boot loop where the phone doesn't get past the first "HTC" logo page. I also notice that there are two thin dark horizontal lines on the top and middle of the screen that weren't there before. They look like clusters of dead pixels and are across the whole screen.
I've tried using the official bootloader to do a factory reset and wipe cache but I'm still having the same issue.
What else can I try? Is it safe for me to unlock the bootloader and try flashing a custom ROM while the phone is in this state?

I'd try to look for an RUU that matches your firmware before trying anything else.

I've tried to find it but I'm not having luck.
Since I'm S-ON I can only flash the ROM with the same firmware and I've figured that I need:
version: 3.35.166.12 for CID: VODAP120 (A1 Telekom Austria).
Now in case I can't find it, I would need to unlock the bootloader and flash a custom recovery.
However, since there is no way to go S-OFF without actually booting into the phone is there a risk of bricking the phone when trying to flash a custom ROM?

If everything is official, I'd send it back and get a replacement.

If your phone has a warranty send it back. For it to bork the way it has it was probably faulty, unless you know something we don't..
You could revive the phone but it may still have a fault.

Hi guys,
Thank you very much for the friendly help. I've found the RUU file and it revived it. Wasn't free though (ir-file.com).
When I get the time I'll re-upload it and make available in one of the RUU threads.
Anyway, the first thing I did was to unlock the bootloader, install TWRP, root and finally S-OFF. If I had TWRP to start with I could have avoided all this hassle and just restore the boot partition for example.
However it does worry me a bit that such a thing occurred out of the blue. Are there any ways of checking if there is storage corruption, bad sectors in memory ect?

Hold the power button and volume down while booting. The OS line will show you the ROM version that you have to look for when trying to find the RUU. You need to install ADB and Fastboot and run a special command to read the CID and other device data. Something like allvars, can't remember exactly, did it a year ago when I got the phone

You mean "connect it to a pc while in download mode, install a copy of fastboot.exe and type: fastboot getvar.

If you need permanent storage for the ruu you got let me know as i have plenty of gdrive space.

Hi guys, I am in the exact same situation and don't seem to be able to find the appropriate RUU file for my phone. Can you please give me some indication regarding how to find it.
So far I managed to unlock the bootloader, install TWRP and attempted flashing several RUU files without any success whatsoever.
Thanks a lot in advance!
Cheers!
