[HELP] Trying to root m8, can't enter recovery/bootloop. - One (M8) Q&A, Help & Troubleshooting

Hello xda community, I have very little experience in programming or rooting phones, and I really need help rooting my phone which I think is the International version of the M8 (or normal I really have no clue)
I've browsed through the internet looking for tutorials and such and I stumbled upon xda, but the noob-proof software I found here didn't do the job for me. So here is what I have:
Using the All-In-One-Toolkit, I successfully managed to unlock the bootloader within a few minutes, I then proceeded to flash a recovery to the phone while in bootloader (tried both the TWRP 2.7.0.2, and the latest version of it) but then I go from bootloader: Hboot > Recovery, my phone restarts, showing me the green HTC text, and the black android font on the bottom. Now, I waited for 20 min or so, but I noticed my phone was doing nothing and just heating up. ( I also tried using the perm root command but the result was also a bootloop)
I ended up holding down the Power button for several seconds, and the m8 started up like normal again. I did my research and I believe it to be a bootloop (correct me if I'm wrong ! )
I then looked for more information on the forum, in the FAQ section it said to simply erase the cache, which I did, but the phone wouldn't enter recovery still. I got really mad
So please help me find a solution or tell me what more info you need ! I would hate to have done a reset for nothing ^^
Thanks!

Post fastboot getvar all result (delete imei & serial no.)
What you described, seems like you probably not have a M8 (as happened to few others)

Really ? Not a M8 ? The box I got my phone from states : HTC One M8s, weird...

Yeah.. correct. Your device is M8s not M8; they are two different device.
Here is the thread for your device - https://forum.xda-developers.com/ht...ral/make-custom-recovery-htc-one-m8s-t3114245
Ask there, someone will be able to point you to correct TWRP version to use.
Anything for M8 won't work on M8s.

Bricked to the Max... (Maybe)

Prologue:
So there I was, caressing my shiny and smooth M8.
At the beginning of the year I S-Offed, and added DigitalHigh's awesome Beyond Stock...
Later on, I used a standard RUU GPE Rom.
After repeated Wi-Fi password amnesia, I wanted Beyond Stock Back.
Flashing "GPE_5.1_M8_DH_080215.zip" gives me an "Error 7" even with repeated wipes... hehe... wipes
Searching didn't give me a coherent answer.
So I though, let's update TWRP... and...
Now
The thing's only usable in Bootloader.
If I go to recovery or ANYTHING, the "Google" logo stares at me in disgust.
Odd detail: I'm using fastboot and when it's stuck on the "Google" logo, entering "adb devices" detects the phone in recovery mode.
I flashed TWRP 2.8.7.0, but all I see is the "Google" logo. (I can still feel vibrations on the screen as if I'm hitting a menu button)
I also tried to "fastboot -w" and it gave me the "remote: not allowed" result.
Actually, I tried to fastboot a lot of things and the result came the same.
Anyways, I'll give a detailed log as soon as I remember how, but the reason I post this is 'cause searching for this doesn't give an understandable or reliable result.
Thanks

Give the output of :

But delete the serial and imei before posting ! If you have an old bootloader you have to use the 2.7 series of TWRP. if you have the latest bootloader (3.18-3.19) you have to use 2.8 series of TWRP !
OOOOOOOOOHHHH, Where I get new M8 bootloader?
Hold Up, going to work, will post 'getvar' later today.
It's there, brah.
Take a look if you can.
It's an AT&T device, you are using it with AT&T ? And you fully converted it from sense to GPE ? You could also :
1: run the GPE ruu again. It will get you on GPE stock again and since you are s-off that should not be a problem of any kind.
2: convert back to sense (original AT&T with software number x.xx.502.x)
i am not sure if the AT&T RUU will cover the "back to sense conversion" so this might be interesting too as it involves the standalone flashing of the firmware first (you need a AT&T firmware, NOT the one posted there !!!)
here is more conversion info :http://forum.xda-developers.com/showthread.php?t=2733523
and here you can get firmwares : http://forum.xda-developers.com/showthread.php?t=2701376
if you want number 2 here is more info with a download link to the latest android L RUU : http://www.theandroidsoul.com/download-att-htc-one-m8-lollipop-ruu-4-28-502-1-75822/

Hi,,
I have managed to remove my OS, without making a backup. All i have running is TWRP. Was going to install CM12.1, but didnt update the M8 to the latest software that contains relevant bootloader. From here it went downhill - fast.
Ended up with no OS, no backkups, and no ability to flash other ROMS i think.
If someone could give me a few ideas, i would really appreciate it.

Your case is different and you should start your own thread but there are many same case as yours.
Here is one and the solution is in there.. run RUU - http://forum.xda-developers.com/htc-one-m8/help/os-sos-t3192177
Anything you're not sure, ask there. Don't hijack this thread.
UPDATE: Thanks to ckpv5 and the links that were provided i was able to complete the reinstall - thank you so much!!
Opps - sorry - didnt mean to offend!
Will take a look.
Thanks
Mike
The RUU got me an OS and, right now, that is all I need.
Thank you!!

I was trying to flash a recovery RUU Zip file using Hasoon2000 all in one Toolkit and it failed. Does anyone know how to fix this?

What version is your phone? Do you have a full RUU to flash? Why did you use a toolkit instead of manual install? What recovery for what version of the phone did you try to install? Can you open a command window and use the command "fastboot getvar all" to give us some details on your phone model? be sure to delete the IMEI/serial before pasting the output here.

Agree with the previous response that we need more info.
Namely, getvar data, so we can see the version (CID, MID) of the phone, current firmware, etc. As well as what RUU file (exact name, source).
Also, any error messages or what wre the exact results of trying to run the RUU?
I also agree that flashing an RUU zip (or just about anything) thru a toolkit is a bad idea. Flashing manually is not any more complicated (at least, not by any significant degree) and a toolkit just constitutes an unnecessary middle man, that I've often seen cause problems in itself. Biggest reason for this, is that the toolkit hasn't been update in over a year (going on 2 years!) and its outdated components cause many issues on even remotely current software/firmware.
I have same problem please someone help me its request

How can it be same problem as OP ? Your problem is installed wrong ROM for your device variant.
You asked where to find your correct firmware and I linked to you to correct section for your device variant
http://forum.xda-developers.com/htc-one-m8/help/htc-one-m8-unable-to-correct-firmware-t3446792
But .. now you installed a GSM RUU on CDMA device... the biggest mistake.
Change back MID to original then install Sprint RUU. If you're lucky enough, Sprint RUU will unbricked your M8.

Your phone is the CDMA version M8, that is a fact. Choosing other carriers has nothing to do with it. Being the CDMA version M8 means it supports CDMA, in addition to some GSM and HSPA bands. Its intended for use in the US with the Sprint network, and will give you limited results elsewhere. Really, its the worst M8 version to buy; and I wouldn't recommend it to any international (non-US Sprint) users.

HTC M8 ONE stuck on HTC logo.

Hey I posted my problem on the other forum, but i figured this one was probably better for my issue.
I recently tried to root my phone with this (cant post links yet) guide, however something must have not worked out because I cant get passed the HTC logo. I can get into the fastboost mode but im not really sure what to do there. I tried the factory reset with TWRP but with no success. Its also in S-ON and i saw that most guides require it to be S-OFF in order to work. Its a European phone.
I dont have any important stuff on it, I just want it to work again.
Can anyone help me?
In other thread you said you have Germany version, now you said it's European version.

You can't link, but you could have described what actions you took, in detail. Otherwise we have no idea what you did, and can only guess.
You probably used an outdated guide (and possibly outdated toolkit), which which mean you used the wrong (old) versions TWRP and old version SuperSU, which results in no boot. For your current configuration, you need to use TWRP 3.0 and SuperSU 2.76.
Also, if you make a TWRP backup before making any mods (such as root) you can easily restore that backup if the mod goes wrong (such as the root not working and causing no boot in this case).

Stuck on bootloop or htc logo when booting to recovery

I tried to root my phone using the tutorial on youtube the All-in-one rooting chuchu but when I got into flashing TWRP recovery it stucks on the htc logo that's why I can't install/flash supersu. I tried to clear cache using fastboot but it still the same. Help please. I tried all other version still the same.

Your case is even worse.
You used tools & twrp meant for M8 but your device is not a M8 but M8s.
They are different, you can't install recovery for M8 on your device, you can't install any ROM for M8 on your device ... won't work.
And you also in wrong section meant for M8.
M8s section is here : https://forum.xda-developers.com/htc-one-m8/one-m8s-general

On the last two pages, someone post a link to the working TWRP for your M8s.
After install TWRP, install latest version SuperSU to root.

Sorry about that. This was just only gift from my father and also didn't know that there is that M8s. I'll go to that section then. Thanks sir!
After you installed TWRP for M8s, make sure to make a full nandroid backup first before you root it.
If something goes wrong, you can rely on your backup to revert to stock as there is not much resources for M8s.

HTC One M8 - No Sound at all

Hi, I recently installed lineage os rom (from sense-rom). So after the installation I was really pleased that the phone was back to normal but later i realize the audio has completely vanished. I can't play any songs, videos start but they are as on mute. same goes for playing videos on Instagram and YouTube. Actually on YouTube I get the error message '' There was a problem while playing Touch to retry''. Even there is no ringtone volume sound, i also tired to change it but its says unable to play. I also tried to recover my recovery of stock 4.4.4 and also did factory reset later but the problem still persists.
Any support would be appreciated. Thank you.

Agreed. Sound issues like this are usually a result of outdated or damaged firmware.

Sure, here you go: https://forum.xda-developers.com/showthread.php?t=2729173
Firmware 6.20.651.3 is what you want. Modified vs. full or signed is up to you. But since you have s-off, the easiest is probably the one with recovery and boot removed. Otherwise, stock recovery and boot will be installed when you flash the firmware; and you will need to flash TWRP again, and also flash the custom ROM (or at least it's boot.img) again.
I'm glad you provided the getvar data in this case. From the results I can see you have the US Sprint variant, with s-off. This combination is a little dangerous. Whatever you do, do NOT try to flash firmware for another (non-Sprint) version. They are not compatible, and doing so won't work, and may even result in a permanent radio brick!
Hello Guys !!
So my brother had htc one m8 for like 4 years he was studying in uk he came back to india in 2016 and purchased one plus 3 and unfortunately he passed away after 15 days but thats not the point, so my dad kept the oneplus , this htc was somewhat dead and was kept in the cupboard for two years and i had my eyes on it a week back i tried to charge it and it actually did show a sign of life though it was stuck on htc screen, wasnt booting up i put some effort and managed to boot it up i wanted to listen to legendary boom sound but strangely their was no sound at all and tried to listen to ringtones but still no sound thought that it must be hardware issue but headphones werent working either, i came on xda read some threads found out that this can be case when rom is damaged it was running on MM sense 7 so i unlocked bootloader and flashed twrp and installed lineage os 17 but still there was no sound so i tried to get it back on stock but all i get is errors , I tried many RUU versions most of the time error was "error 12 signature verify fail i feel pretty helpless cause i wanted get my brother's memories back

Signature verify fail usually means you still have the bootloader unlocked. The bootloader needs to be relocked in order to run RUU. Relock with fastboot command: fastboot oem lock
You also aren't going to find the right RUU by guessing. It needs to match your CID and version number. In your case, there also isn't an exe version RUU for your M8 variant. But you can use the zip format RUU from the following post, using the instruction found there as well: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Also, I'm not sure what you mean by wanting your brother's memories back. Not sure if you are being literal (the actual data) or more figurative. But if you are talking data, that got wiped when you unlocked the bootloader.
Another thing, delete serial number for your post. This is personal data, that should not be posted on a public forum.
