HTC One M8 - 3 (Three) UK - Unlocking Bootloader Possible? - One (M8) Q&A, Help & Troubleshooting

I am planning to install a custom ROM on my phone, and I was looking up how to unlock the bootloader.
I've not unlocked a bootloader and flashed a ROM in quite some time, the last was my old HTC Sensation.
I stumbled upon a thread about how phones from the carrier I'm on, which is Three here in the UK, do not allow bootloaders to be unlocked.
"Three (and phones direct from networks ie. O2,Voda,Orange,Tmo) = SIM LOCKED, and Bootloader unlockable = No. Which means You can Sim unlock the device but Bootloader remains forever locked. Unless someone manages to find a exploit."
That was in 2013 though so does it apply still now?

That thread is for Sony Xperia, its got nothing to do with this phone.
Bootloader unlock should work fine on 3 version (I've seen others with 3 UK version messing with ROMs here). Far as I know, Verizon in US is the only version that doesn't allow bootloader unlock via HTCDev.com (but you can s-off by sunshine for $25 in that case, then use it to unlock the bootloader).

Thanks for the reply

Im on Three Uk, i unlocked my bootloader and rooted and flashed Twrp no problem, s-off i havent got around to, i begrudge paying $25 for an exploit that should be cheaper.
As for sim lock, all phones purchased through 3Uk, contract or payg are already sim unlocked, same applies to CPW, only O2, EE and Vodafone lock their mobiles within the uk.

Is s-off a needed feature? I just want to install Android Revolution HD via TWRP

No, it is not needed .. you need unlocked bootloader, twrp and the rom zip to install.
Most important your current firmware is at least 4.xx.771.x or better 6.13.771.4

It says s-off on a lot of these custom roms, but i dont think its working for me anyway, ive flashed ARHD and Leedroid and Dragon, and although they install, a ton of the roms features and apps do not install, example - xposed, so where am i going wrong, BL unlocked, rooted. Twrp, but customs wont install what they say is included, i think its because im still S-On, and i always will be.

You only need S-off if you wanna upgrade to newer modified firmware or firmware that is not supported by your branding. And that's the main reason, sure there are some other things like unlocking your bootloader without HTCDEV, changing CID & MID and transforming your device into a dev edition but you don't need S-Off for ROM flashing and installing apps that need root permissions such as Xposed etc.

Most of the problems are related to the firmware and kernel.
The best is to run these custom ROMs on Marshmallow firmware. For e.g H3G Marshmallow firmware is 6.13.771.4
Some custom ROMs are on stock kernel with write protection enabled, some ROMs include write protection disable module and some ROMs come with custom kernel with write protection disabled.
You should install different kernel like ElementalX, LonelyX to name a few which include the write protection disabled feature when the custom ROM that you installed come with stock kernel only.
Without write protection disabled ... most apps that require root won't properly working.

To get to 6.13.771.4 firmware on H3G phone do I need to flash an LP nandroid then update using software update?

Yes .. that's a proper way to do it if your device is S-On so you don't need the hassle to relock bootloader and later to unlock it again to install custom ROM or to root it. Relocking and later reunlocking will wipe your data/internal storage. But .. restore LP nandroid and install its matching stock recovery then do OTA, you don't need to relock bootloader
If your device is S-Off, you can simply flash the firmware.zip (as S-Off doesn't need a relocked bootloader)

Thanks. Do you by any chance have an LP nandroid for H3G? I remember you used to have collection does it go up to LP? Or will I have to go back a few earlier versions and sequentially update?
EDIT: just visited your collection thread again (hadnt checked for a while) and found both nandroid and recovery there. THANKS !

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.

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).

Coming in hot

Hey M8 forums,
My S4 recently self destructed and I'm jumping ship to the M8 for T-Mo USA, I have a couple questions to prepare for it's arrival.
I'm coming off the S4 CM12 nightlies, are the M8 builds unified? As in, I can flash the standard CM release on my T-Mo variant?
And can I please get a link to the unlocking and rooting thread? The one I found has a method, but for s-off, the link seems to be down.
Thanks and greetings!
Most info can be found here,
http://forum.xda-developers.com/showthread.php?t=2711073
?
As far as CM goes, I'm not familiar with T-Mobile variants... Sorry. ☺
As of now the M8 in cyanogenmod is unified, all the GSM variants are just labelled as "m8". and the CDMA variants have other names like cm-20140120-m8vzw for verizon.
Onto the rooting and unlocking, you can unlock using HTC Dev but S-OFF might be a little impossible if you get the m8 pre-installed with 4.4.4.
Honestly, to root all you need to do is unlock using the HTC Dev site and flash a custom recovery from TWRP or CWM.
then flash SuperSU not all that different from a Nexus.

I bought it off a guy that bought it a few weeks ago I believe, I haven't gotten it yet to see. It was my understanding that SunShine works on all M8's up to Lollipop. Is that not the case?
And what is a firmware? I keep seeing around to flash the Lollipop firmware, is that just the radio.img file or the whole RUU or what?
A firmware could be reffered to a whole RUU , because the ZIP that updates from 1.x to 3.x is a firmware.
Essentially a Firmware contains the essentials for a basic update (HTC version) , Radio, boot, Kernel, Bootloader, modem, etc.
An Update Firmware or RUU will contain all the partitions ,
boot, system, bootloader,hboot,modem,radio, cache, recovery , and so on.
And to some sunshine will work and to some it might not, it's a risk you're going to have to take, (to get s-off) worth it.
Though we shouldn't have to go through all these cracks and breaks to get it.
I used an older method and it worked for me, never had to use sunshine.

I was told that the older method ceased to work because it required a server connection to complete that is no longer up. And would using a RUU to get to Lollipop put the system back to S-On?
Flashing anything won't touch the S-OFF. You'd have to manually set that back to S-ON (but why would you want to do that!)

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

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.

Hi guys, I got the HTC 10 bell variant at a good price and since is my back up phone I'm trying to put it to the test to change it from bell variant to the US variant, I was reading a lot of threads but im confused, , I unlocked the bootloader, I instaled the twrp, now how do i change the CID ??mine shows 666, and I want to change it to 617 , do I have to have S-OFF?? or I can do that with S-ON since the Bootloader is unlocked , will I get the OTA updates for the 617 after i change it?? (btw i dont want to chage it to 401 international because im afraid i will loose the band 4 LTE )
I'm with bell and changed to us unlocked. There might be a way to do it without s-off like maybe super cid. But to install ruu.exe you need s-off. You will get ota but to apply all you need is to reinstall stock recovery.

You can't change your CID and flash the Unlocked version without S-OFF.
Thanks guys for your replays ,btw nitramus can u pls add a step by step how I did it??I'm new with the HTC
Since you're at the cid part just look for the thread for changing cid and flash ruu. And look at the thread with all the backups for all the versions or stock rom. You will have all you need, latest available rom with ota. To prevent any problems as soon as your phone is ready to use after ruu and you logged in to you account apply ota right away, then flash supersu and have fun.

Yes to convert your phone to U.S Unlocked you'd have to S-off to be able to change your CID. You gotta pony up the 25 USD, which is worth it in my opinion if you're gonna use the 10 as your main phone and tinker with it for a year or two.
Basically follow the steps from this guide, and when it comes to flashing an RUU use the Unlocked one you can download directly from HTC.com

BTW it's very fitting that Bell's CID is 666

OK did that so I have S-off, I changed the CID on the cmd , and than I flashed with RUU_PERFUME_WL_M60_SENSE80GP_NA_Gen_Unlock_1.53.617.5 than update to the latest ones that they pop up to update, nice Thank you ,btw if i want to change S-on will impact the updates or should i keep it S-off??
Personally I don't bother to change back but if security is important for you then maybe. Later depending if you want to change things again depending on what you do you might still need s-off.

If you are rooted and/or have a custom recovery, you can't use the official OTAs. You'll need the stock and never rooted ROM (it has to have an unmodified system partition), and also the stock recovery to flash it.
The easiest (and often quicker way than waiting for an official OTA) is to just flash a firmware.zip package in either fastboot or by the rename/SD card method.
I recommend the ones on this thread. You can find both Full Stock .zips there, that will wipe your phone (because they contain the boot.img), and No-Wipe .zips that won't wipe your phone (obviously) as they have the boot.img (kernel and ramdisk) removed, and also contain the latest TWRP recovery versions instead of the stock recovery.

To add regarding future OTA updates, if you want them directly from HTC you'll also have to remove SuperCID, if you have it. Just having a stock/unmodified system and recovery isn't enough.
And I agree, just keep S-off unless you're making a warranty claim.

I was hoping someone might have the official stock firmware including recovery, from bell? I have to send my phone in for warranty repair. I have my stock system backed up and am on firmware 121.666... I have s-off and boot loader locked status. I have super cid 11111111. Any help will be reciprocated. Thank you for any help.

I have a stock backup in my recovery, might work. Might not lol..
Was thinking of going US since Bell still has not pushed an update out..

Help! Re-lock, s-on, TWRP question

Hi!
I've bought used HTC10 on ebay. Seller says that it was S-OFFed, unlocked via Sunshine and has TWRP 3.0.2-6 installed.
The phone is not rooted.
At the moment:
OTA is returning "Can't update software" message.
Android PAY says "unable to verify that your device or the software is compatible"
My understanding is that in order to fix these, I would need to replace TWRP with stock recovery, relock and s-on. Am I right? Could you please point me to the right guides?
Thanks in advance!

I think the best you can do is check the cid, then flash the ruu, after that use sunshine to lock it/s-on
may be you can also change the cid and flash whatever firmware you want (except jap ver, and cross flash for us/international)
there are a lot of guides, but most of them give you the same result

The CID is "HTC__01 WWE".
Do I need to flash RUU or TWRP Backup / Stock recovery or all of them? The phone is running stock ROM and is unrooted.
Also do I need to buy Sunshine for unlock/s-off or is there a cheaper way?
I will suggest do a TWRP backup first, then flash RUU, in case of anything goes wrong
may be you will want to change cid and flash your regional firmware because volte and language setting are carries/region specific
sunshine can be reuse on the same phone, just go to download the latest version then you are good to go.

If TWRP is installed, then you can root it w/SuperSU.
If it is S-off, you can flash the firmware updates easily yourself; there are guides and an automated tool.
Android Pay doesn't like unlocked bootloaders and root; there may be workarounds for this but be prepared for endless cat-and-mouse if you really want that app (personally, I'll just keep my phone the way I want it and since they don't trust their app to run on a rooted phone, then I don't trust it either.)
Having said all that, any device I get, I completely wipe/reinstall (run RUU in this case) since it really is in an unknown state...especially an S-off phone from eBay.

Thank you!
I've flashed RUU zip using the guide from theunlockr.com. Everything worked as it should. Bootloader is still unlocked (with S-off), but that's shouldn't be a problem, as OTA and android pay are now working fine. I might use it in the future to install CM14 when it comes out.
