HTC One M9 Post-Root Bootloop - Android Q&A, Help & Troubleshooting

DISCLAIMER: I'm completely new to Rooting devices.
My phone is an HTC One M9 running Marshmallow 6.0.1 on Telus.
I attempted to root my device recently to try and solve an unrelated issue that factory reset could not, which is no longer important.
I followed this guide and got all the way up to "Power off your device. Now, to boot into recovery mode.", which I can get into TWRP no problem. However, I cannot push "SuperSU" as it comes up as "device not found"(ADB drivers not installed? Though I got this far somehow). I thought this wasn't a big problem and I could install it later.
Now I'm stuck in infinite boot. The HTC logo shows up, and after a bit it changes and does the animation into the logo for the HTC One. Then it's stuck like this(bootloop?), the longest I've tried being 40 minutes. I can do a fake battery removal and then access the "download" bootloader, regular bootloader, and the recovery (TWRP) no problem still.
If I manage to get SuperSU installed will this solve my problem? Or are they separate issues? Can I flash another image to at least go back to "stock"?
I no longer have any idea what to do. Any and all help or suggestions are appreciated and I'll provide whatever information I can manage.

Further information: I have wiped the appropriate caches(dalvik included) as well as factory reset through TWRP in different instances. I've even downloaded the stock recovery image and wiped again. I simply fail to see what the issue is.
Edit: Managed to get SuperSU installed. I don't know what was different this time. Exactly how many times is it supposed to reboot on its own until it's done? Because it's been restarting for over 20 minutes now.

Need help with a lg tribute that is stuck in bootloop after a factory reset.

I have been reading everything I can find and tried to figure it out myself but the more I read the more questions I have and the less sure I am about trying any of the things I have read.
My problem is with an lg tribute from the company called Textnow. My friend ordered the phone from them and was having some issue she decided to try to fix by doing a factory reset which caused it to be stuck on the Lg boot logo. I tried booting to recovery to fix it. The recovery was TWRP. I was under the impression that Twrp was a custom recovery program that was installed after unlocking boot loader. Best I can tell is the phone was already rooted by the company. Does this sound right?
I messed with it for while but couldn't get anywhere with it because I haven't any knowledge of rooting except what I read . I noticed it kept saying something about simulating actions and figured that out but now after trying to back up and restore and poking around that it says there is no os , I was hoping someone could help me figure out where to go from here as it isn't my phone and I would hate to damage it although my friend keeps telling me to just try whatever no big loss because she can't use it like it is so.
I am not sure what the phone had for firmware because I cant get it on. I only know that it had twrp 2.8.5.0 as recover not the usual android. I can access the phone internal and external through twrp and though pc and adb. I made sure to get drivers updated. I tried to flash the stock rom from its forum but it failed,. any info would be mush appreciated

Rebooting at HTC screen

Hello. I have a Sprint M9. It had been acting flaking lately (I would try to install the latest update, and it would reboot without installing and report that the phone had recovered from an error and ask if I wanted to send to HTC). Tonight, I was trying to use DLNA to play video from my phone to my TV, I was in settings and gave DLNA permission to access my storage. As soon as I did that the phone rebooted without warning and continues in a loop of displaying the HTC logo, then restarting over and over.
I can get into bootloader, download, and recovery mode by holding down the volume down key. I have tried Wipe Cache Partition and Wipe Data, but the phone still will not get out of the loop.
Phone is stock. I have never tried to root or disable S-on or load my own recovery.
What, if anything, can I do to get my phone working again?
Just tried doing what I think is called RUU? I downloaded the .exe from this site:
http://www.htc.com/us/support/htc-one-m9-sprint/news/
It found my phone, and rebooted into download mode. It tried to flash my rom, but shortly after trying to send the file (progress bar jumped from 0% to 100% in 1/2 second). The utility gives me a Error [155]: Unknown Error. I've tried a couple times and get the same problem each time.
The utility reports I have version 3.41.651.21 and tries to flash to 3.41.651.31
Great, now it is telling me my software has been modified. (it hasn't) The only things I've done is run the RUU and reboot into recover to clear cache/data. Bad NAND?
Well, found out why RUU wouldn't work. Low battery. Apparently it ate a lot more battery than I realized while it was in the reboot cycle. Tried manually flashing the firmware and fastboot told me the reason it was failing. C'mon HTC, if the CLI can tell me there's not enough battery to proceed, your GUI utility should be able to as well.
Still leads to the question of:
- Why did this happen in the first place
- This is actually the second time I've had a problem with OTA, with the phone thinking the system had been modified. So either the OTA failing somehow modified the system before failing, or there's a bigger issue afoot. (as noted above, this phone is stock, I've never tried to root, install a custom recovery, or anything else)

Same thing happened to me. The update that Sprint pushed last Wednesday completely bricked my HTC One M9. Same failure mode that you experienced. Sprint technical center was unable to do anything with it, so they are replacing it, allegedly ( been waiting a week for said replacement ).
I talked to a few other people who had the same problem, by the way. Someone in Sprint's QA team completely dropped the ball on this update.
Well, even after RUU it says my system has been modified and the phone will no longer boot into recovery. Just errors back to Download with the message that recovery couldn't launch.
I've also now got intermittent problems with the com.android.settings crashing. So I've thrown in the towel and purchased my first non HTC phone since the original Windows Mobile days.
Hello there. The same problem has come to my mind and the phone has been off for almost a month. Did you solve your problem? If you could solve it, how did you do it? I sent you above the original stock rom set. Nothing changed. The phone developer rum works. but the original 0pja200 rom is starting again.
my phone soft bricked, unlocked bootloader and S-off. Whether it is possible without blocking bootloader flashed RUU rom?

ATT M9 Rooting confusion

Htc M9
unlocked
S-ON
os 3.38.502.31
Hello. i am very lost, very confused, and yeah much help appriciated.
i fix phones for a living, but have never dipped into the development side of things, so i gave it a shot by trying to root my m9.
i installed the android studio ADB thing and of course the htc drivers from htc-sync manager needed to do this.
i unlocked the bootloader with no issue and was able to use the OS just fine after that. after that it was onto rooting my device.
i was unaware of Nanadroid backups or similar programs so theres that
i used superSU 2.64 and TWRP 2.8.7.1a-CTB1-B1 for the custom recovery
when flashing superSU i was prompted it was successful and would now boot into the OS and a few reboots is normal. after waiting a while i knew it wasnt going to go through and that i had screwed myself.
i tried a couple different SuperSU versions with no luck, perhaps the TWRP is too outdated? could not find a way to update TWRP.
eventually after trying multiple different things, on the bottom of the download screen it prompt the 0PJAIMG.zip file was missing, searched for the right one but could not find it.
found an older one and it now gives me an option as soon as booting into the downloader to flash /mnt/media_rw/ext_sd/0PJAIMG.zip or cancel.
selecting cancel puts it intodownload mode.
when selecting "flash" it prompts "RU_MODELID_FAIL modelid in android info mismatched" flash fails, and then turns off.
the phone will reboot continously until power and vol down are held and put into download mode
Can anyone tel me where i need to go from here? What adb/fastboot do i need to be using?
Can anyone spell it out for me? im seriously so lost.
TIA

After Root and LinageOS 15 installation, stuck in eRecovers

Hi all, I am stuck.
I got my Mate 10 Pro (BLA-L29) and wanted to install LinageOS 15. I followed the guide here, rooting and everything went fine. I installed LinageOS 15, the most current build then, via fastboot flash system systemXXX.img. The process went well, the phone rebooted. But since then its stuck in eRecovery Mode. It offered me the "factory wipe" option on the first time, since then I get the options of Rescue (which times out or can't find the files), Shutdown and reboot. It also shows a "this device is not to be trusted" splashscreen during boot, including a link that leads to a 404 on the EMUI-OS-Site. Sorry if that has been asked already i did not find much regarding eRecovery.
I managed to install TWRP, but strangely it still boots into eRecovery. I can force it to boot into TWRP, but it simply will not switch away from eRecovery.
So, what are my options?
1) wait and see, try new versions of LinageOS.
2) use the firmware finder to get the original firmware (any pointers about which one? I'd go for the earliest 8.0 for the BLA-L29?) But how can I get it to the phone since its not an image and the phone does not have a SD-Card? Can I mount it via USB?
3) Get rid of eRecovery or force a switch to TWRP - is that doable?
Any help would be greatly appreciated. I did a lot of custom firmware back when I had the first Desire, but since then I used Blackberry or other, non-rooted devices. I want my control over my OS back.
Thank you in advance, let me know if you need any more information.
Ok, if anyone else needs help:
This helped me, I got back to the Mate 10 Pro Stock ROM

Important: after flashing, you need to remove the USB-cable, otherwise it will just boot into recovery

Device keeps rebooting into recovery. Tried every trick in the book.

Firstly, let me quickly outline what I have done.
Unlocked bootloader
Installed TWRP
Installed a ROM. I wasn't happy with it. It was rooted which of course my banking app didn't like. hideSU didn't work, I couldn't remove root so I tried another ROM.
Once installed I reboot and I have stuck in this loop ever since. I cannot get into TWRP. I've gone into fastboot mode multiple times and tried over and over to install TWRP and reboot into it but nothing.
Worse still is the erecovery option to download latest version over wifi just doesn't work, "Getting package info failed".
Another "useful" Huawei feature if the ability to hold vol up and down to auto install a firmware image. Not helpful when I have no ability to put any files on the device in these modes.
Finally, I have no idea what exact version of firmware I need to download. All I know it is a P20 lite and I bought it from the UK.
Can anyone help? I'm literally staring at this brick stuck in eRecovery.
your try to use hwOTA8, this installs 100% all the firmware (I had the same problem as yours).
nm
Never knew that existed so thanks.
I thought I was finally on the right track but it seems my phone is different from every other one.
I used HWOTA8 and it wants to install TWRP right away. I followed the video instructions and mimicked his movements exactly and when his reboots into TWRP mine does not.
UGH
