T Mobile HTC One M8 has No OS, Please HELP!!!!!!

Hi, I'm a noob at messing with rooting or ROMs, I have a T-Mobile HTC One M8 that I rooted, it worked fine until 2 weeks later it started rebooting every few seconds, I went into TWRP Recovery and wiped the Dalvik Cache and the regular Cache, it worked fine for a few days then started rebooting every minute or so so I attempted to wipe both the Dalvick Cache and the regular Cache again thinking it would solve the problem once more. I went into Advanced Wipe and wiped Dalvik Cache, Cache, Data, Internal Storage and System...it was a noob mistake thinking that I just did a Factory Wipe. I'm not sure why I did that, but afterwards, I lost the OS to my phone because of it.
These are the Problems:
I have S-On
I didn't do a Backup of anything
I don't know how to find the CID (if needed to fix it)
I don't know how to fix the phone
I've attached a picture of what my bootloader shows for its information. Please can someone help me fix my mistake...I really want to learn how to fix this. Can someone please instruct me how to get my OS back? I want to be able to use this phone again.

Download a custom rom and adb push it to your internal storage and then flash it from recovery.

Same problem

Honestly there's a lot of people with no os on bootloader screen.
My os dissapears after unlock recovery s-off and custom Rom.
If your phone is tripping I would just relock and flash ruu in bootloader mode.
First I would verify its not a driver issue and make sure usb debugging is on. If u are on a custom Rom go to there superuser settings and make sure it's set to apps and adb. Then try again.

boot to recovery, sideload a rom. if use adb is to hard for you then download the toolkit and use that to sideload a rom.

I'm no genius on this stuff, but if I were you I'd throw a ROM on the external SD and wipe everything and flash it.
I'm curious why you were having problems in the first place...your phone shouldn't have been having problems like that. It sort of sounds like a kernel problem. Regardless, I wouldn't necessarily flash whatever ROM you were having problems with. If I were you, I'd grab one that tons of other people who are on your carrier are using. Definitely don't flash one that is newer--get something from a well established dev/group.
As long as you can get to TWRP or whatever custom recovery you have, you should be able to wipe & flash without having to use ADB. Not that using ADB is bad, but if you're new, it can be confusing. Let us know how it works out.

can you help?
i dont even have recovery on mine anymore.So, how can i even flash a new rom?

you might be able to get the phone in the boot-loader (power and volume key down key) and then via fastboot flash the twrp recovery and then push a backup to the phone and restore.

Use the toolkit available in the general? section and flash the 4.4.4 RUU. Should return you to complete stock.

Did you get it fixed

Boot loop at the final stap in rooting/unlocking bootloader

I have followed the instructions from Max at galaxynote4root http://galaxynote4root.com/galaxy-note-4-root/how-to-root-unlock-bootloader-on-galaxy-note-4/5/. I got all the way through to the final step which is go into TWRP recovery, install the Oscar kernel and SuperSU zip files. I did not extract these files. Once I did that I got into a boot loop. I get by the Verizon logo to the UI and then it starts rebooting. Since there is not much discussion activity at Max's site, I thought if anyone here could help me.
After the UI comes up and before it goes in the boot loop, I get messages saying "Unfortunately xxxx has stopped." It varies about sometimes it is Knox. S Pen, Google Play, etc.

Try a factory reset by going into recovery and wiping delvik, cache, and data

That improved the situation. It is no longer in a constant boot loop, but it will still reboot when I manually start it or reboot it. When it starts it says "unfortunately KNOX has stopped running." It was doing that before, too.
I have confirmed I have root and and unlocked bootloader.

Redownload the rom.
Wipe data, cache, dalvic cache and system.
Install rom
Then kernel
And supersu.
Reboot and you should be fine
---------- Post added at 06:32 AM ---------- Previous post was at 06:30 AM ----------
If it continues I'd get a Odin flushable and use the pit file for repatriationing of the system. Maybe something went wrong..... Idk

Just a quick question: Did you use a micro SD card as part of the process? Did you remove this card after you were done unlocking the bootloader?
I know the process has you reformat the card, but I am asking if you have tried booting with the card removed.

Just followed your instructions. Everything was fine until I installed the kernel and supersu. I hate to be stuck when I'm so close.

OK, tried that, and it worked--once. When I reboot with the SD card out, it either won't start or goes back into a boot loop.

Although it didn't seem very warm to me, I pulled the battery and let it sit for an hour. When I started it back up, everything was fine.
However, how do I re-enable the use of the SD card. I am afraid if I put in back in, I'll go back into the boot loop?

You'll need to connect the micro sd card itself to the computer and format it there. I have used Rufus (https://rufus.akeo.ie/) in the past to do this, but you may use any formatting program that you are familiar with. I recommend FAT32 as your format unless you move files over 4 GB to and from the card.

Thanks. I've rebooted it a couple of times after doing this, and it still is working! Now, should I install a 6.0 ROM or leave well enough alone?

It will depend on what version of firmware you are currently running. Most 6.0 ROMs require that you are using N910VVRU2CPD1 or N910VVRU2CPF3 for proper use. Please go into About Phone in Settings and check the Baseband Version field to make sure that you have one of those two in there. Flashing a 6.0 ROM with 5.1.1 firmware will cause issues with mobile signal and can make it impossible to use wifi.
If you find that you are running 5.1.1 firmware, then you have two choices: Flash a 5.1.1 ROM and call it a day or go through the process of unlocking the bootloader for 6.0.1 firmware. It's important to note that this will be a different process than the one you just went through. Be sure to research it thoroughly before attempting it. Hsbadr is a great developer and I believe he has a process for that, but it's been a while since I did it myself.

Back in a boot loop again. Once I've loaded the system image, I can reboot several times and everything is stable. As soon as I obtain root by installing the Oscar kernel and BetaSU, the phone becomes unstable. It might boot properly at first, but I still get "XXX has failed to start" where XXX can be any of a number of apps. If I let that go on without first shutting it down, it will go into a boot loop. However, if I do shut it down and restart it will also eventually go into a boot loop. Obviously this phone can't be my daily driver until I get it stable.
Before I install the rom each time, I wipe data, cache, dalvic cache and system.
I wonder if the kernel is the issue?

I need more information to help you out. Please answer the following:
What baseband is your phone at right now? (Refer to my post above for where to find it.)
What ROM have you installed? (Be sure to include Android version as well as name)
Oscar Kernel is specifically for use with 6.0.1 Touchwiz ROMs. If you aren't on 6.0.1 and you haven't installed a Touchwiz-based ROM, then there will be issues.

Thank you. I finally figured it out. The problem was with oscar_kernel_v0.2. Instead I am using Emotion-TW-5.1.1-nightly-r21-RC1-SM-N910P. I'm going to stay with 5.1.1. The only trouble I am having now is with My Tracks not showing the map. I know it's been deprecated by Google, but it still is working on my LG G4. However, I'm not trying to hijack this thread. I'll start a new thread for this issue.
This is now the fastest phone I've used after deleting bloatware and running Nova Launcher.

Good to hear. Enjoy the phone.

OP3 won't unlock 'Wrong PIN'

So I backed up stock OxygenOS with TWRP, copied that backup to my PC, flashed the CM13 nightly to test it, wiped the device, restored original backup from TWRP.
Boots up, asks me for my PIN, this works and so it continues to boot Android.
At the lock screen it says 'Wrong PIN' when it's correct and it's the only PIN I've ever used on the device.
Does anyone have any suggestions that may fix this?
Thanks.

I had the same problem with unlock pattern, idk how to solve it without formatting internal memory.
but you can erase internal memory (factory reset) and your phone will reboot and be clean (wiped everyting including pin)

Yep it sucks, I'm trying to avoid that

This is a known issue with twrp. You should be disabling security (pin/fingerprint) before making a back up. There is a thread on here on how to get around it.

but when i hit wipe/advanced wipe/data then
hit repair change file system then hit change file system
to ext2 then back ext2
it detects internal storage
but when i booted into android it wanted to encrypt data and wipe it.
so i manually wiped data in recovery then rebooted an bam it works
an it still detects my internal storage........yay thank you so much
it just doesnt detect my micro sd card

I'll look into trying to fix it but my SD card words so that's weird

Ok so I tried it on another friend of mines phone and his sd card and everything is working fine so I'm really confused why yours wouldn't work????

Me too I really don't understand it.

I'll keep looking into it for you...I wish other people would let me know how it's working on there device

I didn't realize people were still having issues with twrp on the tmo/Metro variant. Id have to double check with Aeorsyn but im pretty sure we posted one somewhere in this forum that works...at least for me...perfectly with the exception of the time being off every now and then. It flashes zip and image files, makes backups, restores, wipes, works with twrp themes, reads internal and external sd, and even usb via otg. I've been running it for a couple months now without issue. Is there something im missing that people are trying to do that I'm just blind too? Lol if anyone wants a link to the twrp I'm using just lemme know.

Twrp deletes stock rom
Maybe you can help me out, maybe im missing something. I have the g5 (hannah) MetroPCS variant. Everytime I flash TWRP it deletes my system. Ive tried 3 other TWRPs with no luck. One way or another I cannot boot, (bad key). Then I reflash my stock rom and try again. Ive tried with and without allowing system modifications with no avail. However when I first flash and boot into recovery there is a screen asking to decrypt. it asks to enter a password but the screen doesnt respond to touch for the pattern dots. Does that decrypting need to happen for TWRP to work correctly? Thanks

I used Sir's (THANKS!) twrp and just booted it without flashing,(worked great!) it boots fine but asks for unlock pattern and doesn't accept the one I have set, (I'm guessing this is where decrypt.zip comes into play, but unsure), I hit cancel and KEPT READ ONLY , then made individual backups of boot + system + system.image
I also get the Bad key however I believe this is normal after unlocking the bootloader.. If you wait a bit it should still eventually boot.. I'd like to try to make a boot animation..

turns out its not deleting the rom. its a problem with the boot image or encryption . When i first boot into twrp i cannot see internal storage. if i change my partition from ext4 then back to ext2 it shows up and the decrypt.zip is successful. however when i reboot phone it hangs at motorola screen. I then went back to fastboot and flashed stock boot.img and the phone almost booted up. I got hung at decryption unsuccessful perform factory reset. I dont know why this is so complicated any suggestions.

Stuck at lock screen after failing an update

Recently, phone updated itself automatically to 11.0.3 version from 11.0.1. Now it is stuck at lock screen and none of the gestures or buttons working in lock screen(only long pressing power button restarts phone). Phone is china version. I can access to the fastboot and recovery. Can I fix it without installing new rom on it?

Deleting the lockscreen password seems to fix it for me, had this happen a few times. You can do it through twrp, delete locksetting* or gesture* from /data/system.
If you can't mount data, then formatting data is the only way, wiping isn't the same.

You can try flashing back to your previous ROM but I think your only options are going through TWRP to save your data or formatting data.
Maybe someone else can chime in
