Hold down power and vol up for several seconds to force a reboot. The

moment

the screen goes dark to reboot, let go of those buttons and only hold vol down. Don't let go, until you see a white screen with various info on it. This it the bootloader. If the phone simply reboots to OS or Safe Mode, you just had bad timing of the button combo. Repeat the process until you see the bootloader screen.

On the bootloader screen, does it say RELOCKED, UNLOCKED, or LOCKED near the top?

Does it say Software modified, or official?

Does it say s-off or s-on?
[Sprint HTC One (M8)] Erbat:
It says

Tampered

Unlocked

S-ON

About the OS I don't know, the phone already has SuperU app, also I don't know how it works
[Sprint HTC One (M8)] redpoint73:
You need to update the firmware, to do much of any mods (like current ROMs).

You can do so by either:

1) Finding the proper stock nandroid and stock recovery, then OTA update to latest version.

2) Relock the bootloader, and use latest Sprint RUU (will wipe the phone).
[Sprint HTC One (M8)] Erbat:
I'm a bit affraid because I don't know if after to do that my phone still works

It's sprint and I use it here in mexico with movistar so I need something else to do this proccedure? I also searching the topics you told me here in the forum
[Sprint HTC One (M8)] redpoint73:
In your first post, you ask about doing mods. Now you are saying you are afraid to. So I have no idea what your comfort level, what you are willing to accomplish, etc.

As long as you are willing to learn, put in some time reading and understanding, and follow instructions carefully, there isn't much to be afraid of. Any mods to the phone involve some risk. But the risk of permanent damage (a true "brick") are minimal. The worst that is likely to happen, is the phone fails to boot, and you may need to troubleshoot for an hour to 2 to get it back running. But that happens to just about anyone that mods phones, at some time or other. Its just part of the game.

But in the phone's current condition, something needs to be done by you, in order to update the phone in any way; whether it be by official means (RUU or OTA) or custom ROM. Otherwise, it will be stuck on Android 4.4.3 as it is now.

Not sure what you are asking, are you wondering if any additional hardware is needed? You will need a computer for either method I stated, plus the sync cable that came with the phone (or other charge/data cable). PC is required for Method #2.
[Sprint HTC One (M8)] Erbat:
Yes for sure Im reading the past days about the topic and the fears I guess its for my phone became to an expensive brick, but I want to do this, I sent you a PM and I read your answer sorry for do that.

And finally about the last quote, I mean the M8 its originally sprint (on the starts screen says) so I want to know if its possible make the unblock totally to use on any company of the world or the country (Mexico) above than GSM, maybe 3G or in the best way 4G
[Sprint HTC One (M8)] redpoint73:
So it sounds like you already using the phone on Movistar, just not with 3G or 4G?

There is a mod to unlock bands, which seems to work on your Sprint CDMA version (from what I understand). But it requires s-off ($25 by sunshine app) and is a slightly more complicated mod: http://xdaforums.com/htc-one-m8/general/unlock-bands-qualcomm-device-phone-t2880239

So if you are unsure about doing what I've previously described; the mod to unlock bands is definitely the next level beyond that. Mods done with s-off are more risky, and can actually brick the phone (render it permanently unusable).

Whatever you do, do

NOT

try to flash another carrier/region versions radio, firmware, RUU, etc. in an attempt to change the band support. You may see some recommendations to that effect. But this does NOT work on the Sprint version, and will probably BRICK your phone.
[Sprint HTC One (M8)] Erbat:
Sorry I think I don't give my idea correctly, my English is not good.

I wonder if you can make my htc have the most updated software and if it is possible to use other phone network than the GSM because since I buyed (used) has the same software, the same HTC Sense and I could only use the internet GSM mobile network

My phone is

m8_WHL PVT SHIP S-ON *Unlocked*

So I would like to write the correct idea because your help it's usefull for me

really I appreciate your help and therefore not want to lose by confusion or my bad english

then I hope this time to let me know if this is better for your

I'm trying to do my best
[Sprint HTC One (M8)] redpoint73:
Updating the software is a completely separate matter from the phone's band support (3G and LTE bands the phone is compatible with).

I already told you how to update the software, in Post #4 above.

To see if the phone will work with your carrier's 3G or LTE network, you first need to know what 3G and 4G band (or bands) they use for each. Can't really do anything without that basic info. Either research online, or call your carrier and ask them. This is something you should have done

before

buying the phone; as changing to the proper band support is not always possible.
[Sprint HTC One (M8)] Erbat:
The band works on 850/1900, while 4G LTE conection use band 4 - LTE AWS frecuency of 1700 MHz and 2100 MHz.

I work today on the software ( the most important for me )
[Sprint HTC One (M8)] redpoint73:
Sprint M8 supports 3G bands 850 and 1900.

Are you sure you entered your carrier's APN info correctly?

Did you try the SIM card in another phone, to make sure the SIM works for 3G?
[Sprint HTC One (M8)] Erbat:
yes I use the right APN settings but when I bought the guy who sold it to me also told me it was unblock for any company here in Mexico but the problem is that you could not upgrade because when the file is downloaded and is installed, the phone enters into recovery mode and can not be or I do not know if it's my mistake, you can not install at all

He say that if I upgrade or modify the phone I can lose part of the unblock of the phonel and it became unusable here in Mexico
[Sprint HTC One (M8)] Erbat:
I screwed a lot

I don't know what I did wrong on the process of re-stock the phone and now don't start.

only shows the white screen with HTC green logo.

I rememberd when I try to wipe I check all the options and "I swipe to wipe" later when the phone will be reboot

shows me a message about the superU and I install (because already has it)

I was scared and search about this and only found a way to enter on bootloader and says this

*Tampered*

*Relocked*

Well, 6 hours later I have this now:

HBOOT-3.18.0.0000

OS-2.16.651.4

eMMC-boot 2048MB

but when I unlock the bootloader (here's the tutorial of bootloader http://www.htcdev.com/bootloader)

I see the recovery mode once but when I try to do the next step (http://xdaforums.com/showthread.php?t=2755657)

I can not start the recovery mode and I don't do any of progression :(

Also I can see an message saying me the phone hasn't any OS file so I guess that's the reason I can make it start, only turn on and shows the same white screen with HTC logo, I can entered to Bootloader and FASTBOOT but when I select recovery the phone returns to HBOOT and when I turn off and later turn on happen the same (entered directly to HBOOT screen)

Im a bit concerned about that I hope you can teach me how

*Edited now I can enter to recovery I relocked and unlocked again and I can enter again to recovery and bootloader, please help me to put the files of OS

maybe with a SD card?
[Sprint HTC One (M8)] KODEC.4:
Return to stock

Hi Erbat,

first of all it would be nice to get an overview of your device and its versions, you can do this by doing the fastboot command "fastboot getvar all"

The most important version wich you already have is your OS 2.16.651.4, everything what you try to flash to your device if you want to return to stock should match this number or it will mostly fail.

So at this point forget about the Guide with official OTA updates and root access, because its for 4.16.401.10 and you should mainly focus on returning to stock without root to get new updates (easier) ;)

I dont know how much knowledge you already have but just to mention:

Every OS with 2.16.651.4 is for your Sprint version, this means all of the files without 651 will lead in the wrong direction.

Later when you use a RUU ("official" files to return to stock firmware) or a nandroid backup (stock backup created by other users), the files and backups you will find have to match exactly to your OS Version 2.16.651.4 to work.

So at the moment you should focus on returning your device back to stock firmware and OS first, after that you can recieve official OTA updates from HTC :good:

The tutorials/threads you should focus on are mainly these two:

[GUIDE][S-ON] Restore your (European) HTC One M8 back to stock

[tutorial] How to get back on stock with TWRP Stock Nandroid Backups

Edit: You can't use your recovery, because if i understood this right you got TWRP (a custom recovery) before and might have corrupted/deleted it, simply flash the newest version of TWRP 2.8.7.0 with the fastboot command "fastboot flash recovery *NAME-OF_RECOVERY*.img"

TWRP: http://teamw.in/project/twrp2/225/

(If i got anything wrong pls correct me ^^)
[Sprint HTC One (M8)] Erbat:
OK I will try to do those things you've post here.

So tonight before I went to sleep the recovery says I don't have OS installed, that's so confusing because I don't know how install it again, I'm pretty noob so I (if you can do it) explain me a lot to do.

Yesterday already learn to use fastboot and the files and those things to do on the computer, I like to learn and more if is for recover my phone :laugh:
[Sprint HTC One (M8)] KODEC.4:
I know it looks pretty bad for a "noob" if he got no OS on his device and it won't boot anymore, but don't worry as long as you get your phone into fastboot mode you can fix everyting :fingers-crossed:
[Sprint HTC One (M8)] Erbat:
I can't do anything on cmd, my phone hasn't battery today and when I try to do fastboot getvar all say wating for your device and yesterday obviously don't say this

I need wait to 30%? I guess I have readed this before
[Sprint HTC One (M8)] KODEC.4:
Charge it up, restart everything (pc) and try again. You can use "fastboot devices" wich will list all devices connected in fastboot mode (ofc you must choose fastboot in bootloader menu first)

Next could be that you have HTC sync active witch might block something -> uninstall HTC sync

Otherwise you might have driver problems, if so, uninstall htc drivers and sync and reinstall HTC sync to get new drivers. -> uninstall sync only again (maybe reboot)

If all this does not work search for specific fastboot drivers for the M8 and try it with them ;)
[Sprint HTC One (M8)] redpoint73:
You should

never

wipe any of the partitions in the TWRP "Advanced" menu, unless you know

exactly

that they mean, and what the result will be (those options are called "Advanced" for good reason!). Even if the phone was properly working before, what you did was to wipe the OS (system partition) and make it

stop

working!

Further, you wiped any backup files and personal data that may have been on internal storage or the removable SD.

Simple rule when modding the phone: Do

not

experiment or make up your own solutions (will almost always fail and possibly make matter worse); and only do

exactly

what is directed to you from the proper guides, reputable "helpers", etc.

---------- Post added at 10:30 AM ---------- Previous post was at 10:27 AM ----------

Can't help you, if you don't tell us exactly what you did: step by step, in specific detail, with links to the files you are trying to use, exact file names, etc.

If you don't tell us what you did, we can't see what you did wrong.

---------- Post added at 10:32 AM ---------- Previous post was at 10:30 AM ----------

This guide has nothing to do with returning to stock, and is not for your version of the M8.

Nothing good can come of this; for what you are trying to do.

If you didn't know what you were doing, you should have stopped and asked. Learning and reading is good (and I applaud the effort), but don't do

anything

unless you are sure about it. In your case particular (due to your lack of knowledge/experience) I'd recommend not do

anything

unless we specifically direct you to. You seem to be going down the wrong roads, and just want to make sure we mitigate that now.

---------- Post added at 10:39 AM ---------- Previous post was at 10:32 AM ----------

The phone needs to be powered on, and in bootloader-fastboot mode for any fastboot commands to work.

Charge the phone for a few hours, and try again.

We need to get fastboot working, to move forward at all.
[Sprint HTC One (M8)] Erbat:
Sorry I know I did the wrong thing but it was my fear that the phone is not started, I think if I need someone to help me in real time because I'm already somewhat confused about what I did, I remember that I made a backup Htc sync then I foolishly clear that after seeing that no longer initiated cell I started looking for tutorials right here on XDA and found those and it's basically what I've done, load the bootloader and try to make it work with software sprint but I think they have not worked, now I want to know how to install the OS on an SD if I put all compressed in memory and what should be?
[Sprint HTC One (M8)] redpoint73:
HTC Sync doesn't back up the OS (just backs up user data), it wouldn't have been of any help in your case.

You need to get the phone powered on (even if just on the HTC logo screen) and be able to connect by fastboot, then we go from there.
[Sprint HTC One (M8)] Erbat:
OK , so how I re-install the OS ?

I don't know how can I search it also I don't want to do other silly thing and get worst
[Sprint HTC One (M8)] redpoint73:
You are free to search, read and learn, but as I already mentioned, I don't expect and don't recommend you do

anything

unless I (or another experienced/knowledgeable "helper") tell you exactly what to do.

Is the phone's screen on now? If fastboot connected properly? This is the 3rd times I've mentioned these things, and you haven't indicated if either is the case. So if you can't provide the basic information, nobody can help you.
[Sprint HTC One (M8)] Erbat:
sorry bro, Yes the phone is on Fastboot USB right now
[Sprint HTC One (M8)] redpoint73:
But is it connected properly to your PC? Do you get the phone's ID (serial number) in response to the command: fastboot devices
[Sprint HTC One (M8)] Erbat:
No :eek: yesterday this command works but today don't

(also try the command

fastboot getvar all

and doesn' t works too

send me a message "waiting for devices"
[Sprint HTC One (M8)] redpoint73:
There was advice from another user back on Post #19. Either you ignored the advice, or neglected to post the results from doing it. Either way, its hard to help if you don't follow our advice, or respond properly.

Also, try another USB cable, or another USB port.

You can also try to find the device in Windows Device Manager, than pick the option to manually select the drivers, and try the Generic Android MTP drivers.
[Sprint HTC One (M8)] Erbat:
Sorry I did not read because I saw your comment

I did what he were told at those comments and it served me nothing

And with about to your help I have already connected the phone to all ports and remains the same, do you think that if I can go to recovery mode I can install the OS from there? using an external SD memory, mount the program there and try install think that because I have no operating system on the phone does not let me do anything also download drivers most recent HTC page to see if it is that. I don't want to delete or uninstall HTC Sync because there I have all the files I had on my phone like photos and other files
[Sprint HTC One (M8)] redpoint73:
So what you are actually saying, is you did

not

try all the things the other user suggested (uninstall HTC Sync).

The contradictory information you are providing makes it very hard to help.

It also makes me wonder what other advice you decided to ignore.

Did you find the device in Windows Device Manager, and try to install the generic Android MTP drivers? If so, what was the result?

---------- Post added at 03:23 PM ---------- Previous post was at 03:18 PM ----------

Your posts are so lacking in information (and what is given has been confusing and contradictory) that its hard to say definitively whether you "can" or "cannot" do this.

What is the current condition on the bootloader screen: Bootloader unlocked? What is the OS number?

What happens if you select recovery from bootloader? Does it boot TWRP? If so, what version?
[Sprint HTC One (M8)] Erbat:
Yes I tried to install the MTP but I have Windows10 and this option is not available (Also search on google about this) and windows don't

http://superuser.com/questions/950405/windows-10-is-unable-to-load-android-devices-as-mtp-devices

But in other pages says windows already has this option

https://www.microsoft.com/en-us/download/confirmation.aspx?id=48231

and I download the file to install and look it works on my phone

I started to do the other advices but your opinion it's different to the other user so I choose take all your options and ignore the other.

So please keep explain me to do this correctly

The bootloader is Unlocked

the TWRP v2.7.02
[Sprint HTC One (M8)] redpoint73:
No, my opinion is

not

different from the other users. I agree with all he has said. My advice is in

addition

, not a contradiction to his. You need to listen to

both

of us.

I don't know everything, not always right, and others may have valuable input. Listening to only my advice, and ignoring others is a terrible idea. Case in point, I've never used Win10 for even a minute, so I can't help you there.

I can understand if you want to keep your data backed up HTC Sync. But it ties our hands and makes things

much

harder if we don't have access to fastboot.

---------- Post added at 03:40 PM ---------- Previous post was at 03:36 PM ----------

What OS number on the bootloader screen????

I'm getting really tired of you reading the posts carelessly, not following the advice, and not answering the questions clearly or completely.
[Sprint HTC One (M8)] Sloth:
Greetings,

Thread cleaned.

Firstly there is no need for the swearing and abusive posts. Consider this your 1 and only warning. :)

Secondly you should have posted in the Sprint M8 section (as the Sprint M8 has a few differences from the other variants).

Edit:

I took the liberty and moved it to the Carrier specific Q&A. :)
[Sprint HTC One (M8)] EVOuser94:
Hello [MENTION=7227115]Erbat[/MENTION], I will try to assist now.

Edit: I read back and saw you have Posted the info before, I apologize.

(To make things so much less complicated it is highly recommended to gain S-Off via Sunshine Root, though this cost $25)

In order to help you update firmware and get you a working phone again,

Rename this file to Exactly

0P6BIMG.zip

(copy and paste if you feel the need) Place the 0P6BIMG.zip onto the root of your external Sdcard. And reboot to Bootloader, it should then read that file and flash the appropriate updates for your phone.

The file that is provided is a Bootloader flashable RUU, and you must have your phone relocked with the command

fastboot oem lock

This is the file I am talking about. https://www.androidfilehost.com/?fid=24052804347796593

if you run into any problems please let me know, and please don't stress, we got you :)

Thank you!
[Sprint HTC One (M8)] Erbat:
I want to apologyze to [MENTION=660462]redpoint73[/MENTION], [MENTION=4609217]Sloth[/MENTION] for my bad behavior but I'm so stressed and pissed of, it's kind of difficult for:

1 the lenguaje obviously

2 Im completly noob I don't know as much as you

3 I'm not rich to buy a new one like no matter what's happened to my phone

So EVOuser94 please need your help to make this piece of metal came alive.

I do any thing you say.

Update:

I try to install on SD card an Android_Revolution_HD-One_M8_51.0_584a64.zip

installed at 100% but the phone doesn't turn on and I push Power button + Vol up + Vol down

and it load bootloader again, so when I try to turn on inmediatly starts the bootloader.

also again the info what's show for the screen

To get fastboot working you need to plug it into computer and boot into Bootloader then select fastboot, your computer should automatically install drivers for it, in the worst case scenario we may have to create our own fastboot folder
[Sprint HTC One (M8)] Erbat:
Yes, this move I did before you wrote me ;) Im only downloading the file you say to me nothing else

I download the file, renamed, put onto the SD card, but I can't relock the bootloader, send the message:

[Sprint HTC One (M8)] EVOuser94:
[MENTION=7227115]Erbat[/MENTION]

Okay rename the file to something like 0P6IMG1.zip just so that Bootloader does not recognize the file type. We will rename it back later once we get fastboot working.

Now on your phone boot to Bootloader. Power off then Vol down + power. Then use volume keys to select fastboot option. Report back when you are there.

To get fastboot working Download and run this https://userscloud.com/68s3nkqvv8g0

Press Y to install Adb and Fastboot

Press N to install to just Users

Browse PC to C:\Users\*YourComputername*\Adb

then Shift+Right click in that folder,in the right click menu should be a option that says Open Command Window here.

click that

Type Fastboot and press enter, if it shows a list of options you have fastboot

Type fastboot reboot bootloader

wait until bootloader is showing

Type fastboot oem lock

reboot phone

rename 0P6BIMG1.zip back to 0P6BIMG.zip

power off phone

press power + vol down

let Bootloader flashable RUU read, then accept the update.
[Sprint HTC One (M8)] Erbat:
I do all the instructions but when I try to do the "fastboot reboot bootloader" keeps sending me the dmn message waiting for device
