Unable to boot Red Triangle - One (M8) Q&A, Help & Troubleshooting

Hello All
So I wanted to root my AT&T HTC One M8
I followed instruction from androidcentral...
Now my phone will not boot up it keeps booting to TWRP in recovery only... when I boot to the system I get red triangle and exclamation point
After reading on xda they (androidcentral) had me flash my boot image instead of booting to it....
My phone is not booting at all any suggestions?
How can I get the original stock boot image for the AT&T?
I got the latest recovery image from Mr Hofs's post, but where can I get the boot image?
Also anyone has videos on how to root and s off the m8 not m7
Thanks!!!!

What do you see for sdcard size when you go to Twrp> install?

Nothing anymore...
I downloaded a backup from the thread collection of stock backup and flashed my boot and recovery and now the phone just sits at the HTC logo.
I am able to get to fastboot etc...
Does this mean I am missing the OS?
None of the backup has my CID on it so I don't want to backup from it.
Any suggestions?

Never mind. Went to the AT&T and found that someone made a backup
Going to use the backup copy and go from there
Thanks!

[Q] another person stuck with HTC splash screen

I have a Canadian HTC m9 , bootloader unlock, Twrp , rooted.
i was going to do a OTA to get the fix for the camera and heat issue. however on the process to revert back i end up stuck on the HTC splash screen with recover twrp acess .
what i did is did flash my backup file before the root and tried flashing stock recovery file. but no luck.
i tried flashing again the twrp and still no luck. and everytime i tried to reboot it shows NO OS installed.
any suggestion on what i can do to fix it? im kind new in HTC, i read upon the forum and not sure where to get RUU or the right ROM or if i should flash does stuff..... can i get some help?
I would suggest you flash the latest recovery through fastboot (2.8.6.4) from here https://basketbuild.com/devs/Captain_Throwback/One (M9)/Recovery and try to flash a custom rom or run an RUU if there is any for your variant

you solved the problem at the meantime?
if not.
push via adb a rom.zip to your sdcard and flash it via twrp recovery
yes it did fix it, i was able to boot the phone up again however, can i still flash my original back up so that i can get OTA? i tried using Venon ROM and according to them i can get the OTA but when i tried to update it no update available and i know there is one. i check my build # it still the old one, 1.32.401.17 CL506785 release key.
any idea?
thanks for your time.

stuck at twrp recovery / recovery only starts for a split second

I've been trying to root my HTC m8 and everything was going perfect until I went to load the twrp recovery in order to access supersu. I followed a youtube guide and everything was fine, but now whenever I try to load recovery, it will either say loading recovery and then go into my stock OS, or it will be stuck at the recovery screen and I'll have to power down the phone.
Is it because the twrp recoveries I'm using don't work well with my hboot? I'm completely new to this stuff so I have no idea what the problem could be. My HTC is from At&t and my Hboot is 1.61 and I've used twrp recoveries 2.8.7.0 through 2.8.4.0 and none have worked. I've also used 2.7.0.2 and the philz_touch_6.26.6 with same results.
I've erased the cache after every flash recovery, and rebooted the bootloader before I recover again. If I'm overlooking anything or doing something dumb please inform me! I have no clue what to do now...
Are you sure it's a HTC M8 ? hboot 1.61 is a HTC M7

Boot loop issue

Hey guys, I just recently got some parts for my old One X to start playing with it again (bored with ios). I was running an older version of ViperXL and wanted to get lollipop so my goal was to put CM12.0 on my phone. My recovery was twrp but a version that was older so I had to update it. The in app update wasn't working so I updated cwm instead. When I did this I tried to boot to recovery and it would attempt to go to recovery but then boot back to the os.
Then I was trying to flash the recovery using fastboot which resulted in the same problem. Somewhere in there I flash the recovery.img as my boot image (sudo fastboot flash boot recovery.img) This made my phone repeatedly try to boot into recovery. I tried flashing new ViperXL boot.img as well as a couple others but none let me get into my os again. Now it is just a bootloop trying to start my phone up.
When I try flashing a .zip I get the error 'FAILED (remote: not allowed)'. Flashing recovery and boot images work though.
I've tried a lot and done a lot of searching but nothing can get me into recovery or even out of any sort of bootloop.
I'm using Ubuntu and my phone is S-On if that means anything.
Thanks!
Try restoring any backups of old roms from the recovery. Make sure Recovery is written properly in recovery partition. If this works fine , the appropriate boot.img shud be automatically flashed , i guess.
If u dont have a backup , try finding another one x user using a custom recovery, create a backup from his mobile and copy it to ur sd card by mounting it thru recovery and restore it.
If it doesnt work , wipe all the partitions - System , cache, boot and recovery.. then try flashing a Recovery and then a Boot.img and a rom.
I havent faced such a situation. Just my suggestions as no experts have responded.
Cheers if u have already sorted it out !!!

Semi-bricked XA1, possible recovery?

So my phone has been lagging a whole lot using the stock rom and I have decided that I'll try a custom rom to see if that changes anything. So I came here and saw this forum:
"https://forum.xda-developers.com/xa1/development/half-gsi-oreo-8-1-t3902259"
I thought I'll try and so I unlocked my bootloader, only to have my phone be reset (not a problem, everything was backed up). It also boots with a warning "Device unlocked and can't be trusted".
Then I went on to download TWRP using this link in that post: "https://mega.nz/#!FQFXCYSY!DgxQRkaY1Eqq3B0fZLEQBNzUs0Zj80L6IzSHxdorQ3A" which is the TWRP 3.3.0.0 V2 IS FOR ALL USERS.
I didn't want to flash in the event it was the wrong recovery so I tried booting into it, fastboot boot recovery.img
It flashed, everything was ok and now the phone doesn't boot. It stayed in a boot loop. I went ahead and flashed recovery this time, no luck. Downloaded a recovery.img from another website and it didn't allow me to boot to android or recovery.
Is there a way to save my phone, I can't get another phone until August due to contract. It can still boot to fastboot and gets stuck when trying to boot to android. It being able to boot to fastboot makes me think theres a chance to flash a stock rom or any custom recovery and rom to get the phone working again. Any help? Thanks!

OK use the boot.img and recovery.img made by @janjan HERE. Under the heading ¨Downloads¨ see ¨Xperia XA1¨ and download the KERNEL + RECOVERY the boot.img and recovery.img are compatible with the G3121-G3112-G3125-G3116-G3123 devices on the applicable firmware.
Flash BOTH using fastboot. The boot.img is patched to allow TWRP to boot which it will never do using the stock boot.
If you wish to go back to stock then simply use FlashTool to flash the stock fotakernel.sin and boot.sin contained in the firmware for your device.
Does it works becouse I boot my g3116 from flashtool camand was
Fastboot boot boot.img and then also it's stuck into bootloader

htc 820 stuck in recovery, cant boot to os.

hello I am trying to fix this old phone which keeps bootlooping. I can't get to the OS, and the bootloader won't show. When I try to go to the bootloader, I get to the recovery screen. I tried looking for an answer on google but all of the ones I found needed me to boot to the OS first. please link me to a tutorial for how to fix these, and explain like you would to a complete newbie. Thank you
This what you will flash the stock recovery of your phone since is booting into recovery. Now have in your sdcard the stock firmware renamed to whateva your line of desire is 0pjfimg etc. Now when your reboot your phone it will boot into the stock recovery there is an option for bootloader/hoot screen.The phone will see the firmware when it boot into bootloader. So and let me know ok.
