Software problem, feeling lost..

Hello everyone
I've got a problem.. I've recently bought an M8 of my mate who tried to root it and what happened he messed something up and it was stuck in bootloader (until now), I kept reseting the device back to factory settings and it finally booted up and I managed to get to the main screen of the phone however, wherever I go it shows error messages, for example: 'Unfortunately, Messages has stopped' and it keeps popping up on every single app. I am able to get into the settings and access everything there but to me looks like the software has been corrupted (I guess I have not been told the actual truth what the person was doing with the phone).
Now, I need some good help here guys, I'm new to HTC, never had one so I don't really know how flash software on it. What I would like to do is get the root out of it for good and install clean, not modified software. Basically I would like to have the phone as it is from the box. Original, without any modifications on it. I will be really glad if somebody help me as I can't find my answer elsewhere..
Please guide me step by step what to do in this situastion, what software do I use, where do I get the latest non branded genuine, not modified software and how do I wipe the root off the device so it is like new.
Also when I was in bootloader it said this:
*** Software status: MODIFIED ***
***Locked ***
*** Security Warning ***
Any answers will be very much appreciated.
Thank you, Matt.

There is guides to remove root and such but if your phone is S-OFF I recommend never going back S-ON, why?? because S-OFF is impossible to get on the latest firmwares if you ever change your mind.
So alternatively I recommend running a RUU instead, find out what version you have, is it a GSM (AT&T Straight-talk) or CDMA(Sprint/Verizon)?
Then you can get a RUU from the HTC Official Site, its so simple, run the program as Administrator in Windows with your phone plugged in and it will do all the work for you, and your phone will reboot like a brand new phone with no root, in the background will you keep S-OFF of course if you have it already, you should be able to receive OTA updates as well.
Also an extra little hint, if your device is S-OFF and IS GSM then you can run the "developer/unlocked" RUU only if you wish, giving you a more stock HTC experience with no Carrier junk apps.
But how do you check if you have S-OFF or not? an easy way to check currently is to turn off your phone, then hold down VOLUME DOWN and POWER button at the same time until the bootloader screen appears.
If your device is S-ON then from what I believe you can only run the RUU made for your phone "AT&T for example, carrier RUU only"
Troubleshoot RUU: "My phone is not proceeding with the RUU keeps giving me error" put your phone in bootloader mode by the instructions above and make sure you see "FASTBOOT USB" on the screen, if not use the power button to select the "FASTBOOT" button on the screen.
"My phone won't go into bootloader" unplug your USB cable then try doing it.
This entire method should help you without needing any ADB or fastboot knowledge or files, if you simply wish to go back to a stock day 1 experience.
EDIT: Also I forgot to mention you must install the "HTC Sync Manager" from the top of the screen link I sent you, simply install it and then UNINSTALL the HTC Sync Manager app while KEEPING the HTC Driver Installer app... so avoid removing that from your Programs and Features list on Windows, you simply need the drivers without the software but that's the only way I know of how to get the drivers.

Sunshine works fine to s-off latest firmwares, it's not impossible.
@ O.P
Just do the fastboot command :
fastboot getvar all
And post that outcome here WITHOUT your serial and imei number in it (these are personal so delete those lines) then we can check what you need before jumping conclusions to install a certain random ruu ! And check the OS number in the bootloader and tell what it's saying.
Here is also a guide to fastboot

Stock, unrooted M8 boots only to recovery/bootloader

Hello,
As mentioned in the title, my M8 is having a bit of trouble. Earlier this week, my encrypted device would not recognize that it was encrypted upon restart. Hence, a call to Verizon, and a transfer to HTC occurred. The HTC representative said to download HTC Sync Manager and run the repair tool for my phone. I did that and unfortunately the repair was not completed successfully (even after numerous attempts with various USB cable/ports), so I am stuck with the present problem. A subsequent call to HTC proved futile as my phone is no longer under warranty. I've search this forum and discovered a similar incident involving an international device which did not appear to be resolved amicably.
I've made no attempt to root or otherwise modify device software.
Ideas?
Tom

I assume you have stock recovery? If you are stuck in bootloader mode then try using fastboot to get into RUU mode. I'm curious to see if you can because I've never ran into anyone NOT rooted or have a stock recovery.
"Fastboot oem rebootRUU" with out the quotes. If you can't get into RUU fastboot mode then I have no ideas to help you...

HTC M8s - UNLOCKING, S-OFF ETC

Hi,
So ive spent at least a total of 12hours on this phone trying to unlock it. - im only posting this, in the hope to spare a lot of other peoples time by sharing my experience and hoping to get some advice.
I have submitted an unlock via IMEI to 3 different servers to retrieve the factory unlock code, and all codes ive got are not unlocking the phone.
This phone belongs to a customer of mine, and had started into the venture of unlocking it alternatively as they wanted the phone unlocked some how, i had explained its possible with root and custom roms etc.
So i started my venture and have come to very little success.
I had downloaded TWRP recovery and unlocked bootloader, and once it was installed and flashed with fastboot, my phone would not turn on. - i had used HTC M8 files, and not HTC M8s files - i was stuck in M8 recovery. - i had used these files as any search for HTC M8s would fill up with just the M8 edition.
Endless playing with different combinations of buttons, just holding the power button for a long time got the phone to boot up. (if i left the phone off, and had it charging, the charging logo would show up on a "bootloop" and would not power up, back to the "bricked" mode it was in. -unplug charger and playing with combinations of buttons to get back on)
(If your in this state and panicking, dont panic, your phone is stuck in m8 recovery that i flashed and holding power should kick you out of it, make sure your usb isnt connected)
Enter fastboot mode holding volume down and power and flash htc m8s TWRP-recovery solved all issues with recovery loops and boot errors.
It took me a long time to find the M8s TWRP and recovery files, but on flashing them, my phone booted into M8s recovery and i was able to install SuperUser and root phone.
I was then at the situation of turning the S-On, to S-Off. - More problems.
The tutorial i followed was suggesting to use firewater, and after endless rebooting and downloading SDK files etc, couldnt get S-OFF as i was getting error PID file format only. - HTC has patched this method - time to move on......... FIREWATER DOES NOT WORK.
I was trying to avoid the situation of paying any more to unlock, so giving up had turned to the Sunshine S-OFF tool. This costs $25, and is a simple android app to turn rooted devices from s-On to s-OFF. - I installed and downloaded it to find HTC M8s is not compatible.
A message to all HTC M8s Owners looking to unlock there device for Free, or as a last resort if factory unlock is not available. ---> As of this date, its not possible to turn S-OFF without a "javacard" which is a device to plug into sd slot and magically turns it off.... sorry. - Thus not possible to unlock via root.
If there is a solution, please do let me know, this phone has eaten me up. I have to go to the service provider and try get the code from them.

You talking about sim unlocking ? Even with s-off you can't just sim unlock it, even with a custom rom you can't just sim unlock it.
Firewater is offline now for over a year already and if sunshine isn't compatible there is just no (affordable) way to s-off.
All those methods are not working anymore. You really need a working code or help from the carrier.
Bootloader unlocking and running custom roms or rooted stock is totally different to carrier unlocking a device. And also would like to mention that the M8s is not very supported with custom roms. There are about 2 roms i know of.
And make absolutely sure that you know what you are doing and create a pure STOCK NANDROID BACKUP (one before you pushed root) so you are able to bring the device back to stock for future ota updates.
You can not update a rooted rom (also not a stock one) once rooted the system is changed and can't be undone so you definitely need a "never rooted stock rom"
And the needed files are easily to find actually because there is a dedicated thread here for the M8s.

HTC M8 stuck in bootloop

Hi guys,
Got a phone a need to revive. I received unusable. Mother gave it to my sisters friend and she said it doesnt work. I now see why cause he was trying to mod it.
I managed to once get into TWRP but cant anymore. It was UNLOCKED but now RELOCKED which I possibly made it a little harder for me.
So currently "fastboot getvars" reports back all the info. It's showing version-main 6.13.206.5 and I just want official O2 stock so can use the phone. Ideally sim unlocked but could hassle O2 for that later since it was my mother's contract.
Basically just want to get a working recovery image on and then flash stock. CID is 02__001
Any suggestion to revive this welcomed, please.

So it still have twrp on it ? If yes, boot to twrp recovery then restore the stock backup.
You can find all you need in my thread - https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Post #1 - how-to
Post #3 - you'll find the O2 stock backup
Post #5 - you'll find O2 firmware, install firmware after you restore the backup

No, I cannot get into it. When I select HBOOT, then select recovery it just shows white screen, ANDROID and then back to the menu. TWRP no longer works. That's what I'm trying to fix or put on a stock recovery image and then stock OS/firmware.

Just wondering if I need to UNLOCK it again and also do I need USB debug on. I cannot boot into OS so unable to set USB debug.
To UNLOCK bootloader can that be done if you can only get into bootloader menu? S-ON is enabled but not 100% that will stop recovering it? That's just for signed rom/firmware and I just need something stock.

You don't need usb debugging on to unlock the bootloader as it is done on fastboot mode (bootloader).
First I suggest you install the O2 firmware only then see whether you can boot to OS (assuming the OS is still stock base)
Second, re unlock bootloader with unlock_code.bin that you can get from htcdev.com, install twrp 3.x and restore the stock backup and relock bootloader and reflash firmware. This will get your device to fully stock.
So far, I don't see any RUU for your device version that you can get for free, only paid site has it.

Relocking the bootloader renders the phone unable to boot into OS by definition, as it expects RUU to be run (but as mentioned, RUU is not available for your CID unless you pay - but it's not needed).
Also, you can't flash TWRP with a locked bootloader, again by definition. The primary limitation of an unlocked bootloader, is that it prohibits flashing unsigned recovery images.
So as suggested, simply unlock the bootloader again (with existing unlock bin code, or get a new one using the HTCDev.com process again). Then flash TWRP and a stock TWRP backup using ckpv5's backup collection (linked in his signature).

ok, well made some progress.
unlocked the bootloader the official way. Very quick which I was surprised.
This then repoened up the recovery menu working.
then used fastboot to install latest twrp
then installed S.Team-JW-7.5.0.zip !!!
The install and everything looked good, no errors and now just not turning on. I think now it's a brick? Does not seem to be coming back to the bootloader menu and certainly does not try to boot.
Wondering if end of the line. Any suggestions? I assume need to get into TWRP and flash stock update from ckpv5.
Must say thanks for replies guys. ckpv5 you done some good work on here.

It's really hard to brick this phone (especially with s-on) just flashing TWRP and flashing ROMs. Probably not a brick.
At what point exactly did it shut down/not reboot? ROM installed with no errors, and when you tried to reboot, it went dark? You aren't specific on this point.
How much charge was on the battery when you were flashing the ROM? Did you leave it a long time flashing the ROM, or rebooting, that simply may have drained the battery to shutdown?
Try leaving the phone on charger for several hours, then hold power+vol up for a minute or so, and see if any change (even if just stuck on HTC logo screen).

Hi there,
Well I expect the bootloader to be separate from the rest so we can get into TWRP and normally get out of this situation?
The ROM install finished, battery was at about 80% and everything looked good and I let it reboot the phone. And then it went dead. Right now the PC keeps beeping as a device has just connected and then again as though it's disconnected. I'm watching the device manager and dont see it listed during the connect but device manager tree refreshes. My S7 edge shows up. It flash an orage dot twice, so appears to be a in loop.
I charged the phoned and no luck with any of the power+ vol +/- keys. No response from any of those? I let the phone sit till flat and no orange light and then charged it today and still nothing. Not sure if it's a bad battery but it was up at 83% showing in the TWRP menu and working plugged or unplugged.
It's become a challenge now to make it work, I havent had to mod phones since my HTC One which got heavily modded and then back to stock. I stopped doing that after modding every phone I had since HTC Desire Android 2.3. So been about 4 years since doing all this again. Never had one that was totally bricked.

You are correct that bootloader (AKA hboot) is a separate partition, isn't touched by TWRP, and in fact is "protected", and can't be modified with s-on. Only an official signed zip (RUU, OTA, zip) can write to hboot when s-on, which is one of the reasons why I say this phone is hard to brick with s-on, just by flashing TWRP and flashing ROMs.

You won't connect to the phone by PC in any way, unless you can get the phone to power on, at least to bootloader.
A few additional suggestions/comments I made to another user (in another thread) who by strange coincidence has a very similar condition (apparent brick after flashing a ROM): https://forum.xda-developers.com/showpost.php?p=73062871&postcount=10
But to be honest, it's not looking too good, since the condition hasn't changed after charging and trying the button combos.

Cheers for that. Not getting much except for the 2 brief flashes of orange light.
Any chance the battery is totally messed and this is the problem?

It's possible. Or it might be something else like motherboard or emmc. It's impossible to say for sure.

European Stock One M8 stuck in HTC logo

I have a european One M8. I turned it off when I got in the plane and after landing it never started back
It gets stuck in the HTC logo.
Some times it moves on and says that "android is updating 165 applications"...and when that finishes it says that Sense Home has crashed and shows the HTC logo again (strangely I can change the volume at that stage ).
I tried to enter Recovery and did a Factory Reset but still nothing. When I select the Recovery option inside that menu I only see an icon of a phone with a red icon, no options to wipe cache etc...
The phone is STOCK, S-ON, no root nothing.
Any suggestions? Can I just reflash the stock rom?

Possibly. What does it say for OS number on the bootloader screen?
Also, please confirm near the top of the bootloader screen, it says LOCKED (versus UNLOCKED or RELOCKED).

I seem to have similar problem.
After Factory Reset phone went into White HTC Screen and stopped. I'm only able to access Bootloader and Stock Recovery now. There is no OS.
OS.1.21.401.1
HTC___001
HBOOT 3.19.0.0000
S-ON
LOCKED
Software Status: Official
I tried to Unlock bootloader. I used Hasoon's tool. I confirmed YES to unload bootloader. But after restart Bootloader is still locked.
I tried to flash boot.img and recovery.img but all FAILS.
I can access the phone via ADB but anything flashing always fails. Tried sideload via ADB in Phone's recovery. But always Fails.
I can't access SD via Recovery, says E: mount fail. Tried to re-format the SD but no result
To me it seems like bootloader is corrupt and seems that without proper hardware I won't be able to do anything...
I spent many hours now and about to give up. Please let me know if I missed anything before I will, sadly, have to try professionals.

Hey, thanks for the reply. I haven't managed to do anything neither did I spend a lot of time on this. I was waiting in case someone could help. Such a shame if the phone is bricked. I do not know if it is worth taking to professionals as its value as a used phone is quite low at the moment...

Unfortunately, I don't think your version has an RUU (or from a free source, anyway) that would restore your phone fairly easily (assuming the problem is software, and not hardware).
That being the base (no RUU) you can restore by unlocking the bootloader, installing custom recovery TWRP, and restore a stock TWRP backup (stock ROM).
So it is possible to recover (again, as long as it's not a hardware problem). But it's not a short/simple procedure, if you aren't familiar with these terms and methods.

I fixed it by unlocking the bootloader from HTC's website, installed TWRP and then flashed the LineageOS Rom...

Nice work. It was hard to tell from your post, your level of knowledge. Did you have to learn how to do this, or had prior experience unlocking bootloader, TWRP, etc?
I was on vacation/holiday last week, and not on XDA. So sorry it took so long to get back to you.

Thanks for the help. I have had previous experience installing custom ROMs on HTCs
(HTC Diamond, Wildfire, Desire, Desire HD, Desire S, One S, One X and now the One M8 )
I was just hopping I could get an easy solution without having to go through the whole process
