[Q] Sprint HTC M8 stuck in boot loop and unable to access recovery

My m8 is stuck in a boot loop and i am unable to access the recovery to factory reset the phone. Its been like this for 2 days now, and i have not found any solid help on the matter. I can get into hboot, however fastboot does not work and i cannot get into the recovery (the options are there, but when i press them they just disappear and nothing happens). If i connect the phone to my pc, the fastboot usb option shows up.
What im looking for are some step by step instructions on how to fix the matter. Ive posted on the /r/techsupport subreddit, and ive been told to either use an RUU or try and reflash a recovery, but without the instructions on how to do so.

bootloader bricked. Ruu Failed. Need HELP!!!

Hi guys,
I am feeling quite panicked right now since I flash the wrong firmware (lower version) which leads me to failed RUU "Too many links" and then when i reboot to bootloader it constantly boot into four triangles and unable to fastboot oem rebootRUU at all to reflash and my bootloader are in a messed.
I have the same exact problem as this guy http://forum.xda-developers.com/showthread.php?t=2459221 but i don't really understand to solve the problem as i'm not an expertise in this type of problem.
I can still access my phone by manually using "Fastboot oem boot" but other than that i can't power up my phone or boot into bootloader as i have four triangles in each edge of my phone and orange-colored "RUU". I cant flash any rom or firmware or going into my TWRP.
My Phone is S-OFF and Unlocked bootloader.
Here's My partition 19 if needed to solve this issue.
Help me please !

First before sending you the modified misc partition, can you please tell us what you have flashed exactly (provide link) and more info about your devices (fastboot getvar all) or at least your CID, MID, Version number you was on before flashing?
I see in your misc partition that the RUU flag is indeed active.
---------- Post added at 04:39 PM ---------- Previous post was at 04:24 PM ----------
however here it is: https://dl.dropboxusercontent.com/u/77459918/p19noRUUflag.img
Code:
fastboot oem boot
then copy the file to the root of your sdcard or you can push it using
Code:
adb push p19noRUUflag.img /sdcard
then to restore it to your misc partition
Code:
adb shell
su
dd if=/sdcard/p19noRUUflag.img of=/dev/block/mmcblk0p19
exit
adb reboot-bootloader
and then flash your RUU.zip and make sure to flash it correctly.
Code:
fastboot oem rebootRUU
fastboot flash zip name_of_ruu.zip
fastboot flash zip name_of_ruu.zip
fastboot reboot
Don't know what ruu you need, if you need help choosing one then post your "fasboot getvar all".
And be very very careful with the "dd" command. If you make a typo, you can brick your phone foor good (writing to the wrong parititon)

IT WORKED !! My Bootloader went back to normal !!! You are a savior and making my day better
Thanks !! Your explanations are really clear and very easy to understand that i able to follow all the steps correctly with ease : )
Well I was using ARHD 71.1 and planning to dirty flash to ARHD 90.0 if possible. Then I was using 5.x.401.x firmware that was used in ARHD 71.1. I have seen that the new ARHD 90.0 are using the latest 7.15.401.1 so i flash to that firmware directly before I plan to install the ROM. And I forgot to place the ROM to the SDCard which then requries me to boot to the O.S in order to access the storage. Then suddenly when i restart my phone, My Phone soft bricked where the phone is stuck at black screen constantly while usually the phone should properly goes to the "HTC One" Phrase and then goes to the O.S but in my case, It first boot into the htc green logo and after a while the screen goes black screen.
I thought the firmware is incompatible with my arhd 71.1 so i downgrade it again 5.x.401.x and then while updating the RUU, I receive "Failed : Too many Links" which quite made my worried so I restart the phone to try if downgrading to the older firmware would fix the issue. But then, the "Four Triangle" issue rise.
I am grateful that you have solve my issue regarding this matter and I cannot be more happier than this that everything went back to normal. Thank You So Much! :good: You are the best !

[Q]Stuck in boot after root attempt, even after factory reset. Help!

Hey guys, last night I tried to root my device (XT1058) following the guide [here](http://forum.xda-developers.com/moto-x/general/howto-root-moto-x-ver-4-4-4-xt1060-t3118342). Stupid me decided I wouldn't need to go back to stock ROM like it says in the first step. I continue with the guide, follow every step, until I reboot. After rebooting my Moto X gets stuck at the white screen with the blue circle M. I panicked, read a lot of things online, followed them, and nothing worked. I reset the cache partition in recovery mode when rebooting into fastboot, still nothing. I also noticed that my device is no longer detected in ADB at all, even in fastboot. So after just giving up, I read online in multiple places going to recovery mode, and wiping the whole phone/factory resetting would fix it. It still is not recognized by ADB or finishing booting. I realize I should've been more careful. Please help!

First thing... when the phone is in Fastboot AP menu, you can't use ADB. ADB wont work and wont see your phone unless the phone is fully booted. (i.e. adb.exe and fastboot.exe use two different modes on the phone).
Next, I've seen that symptom before, but I don't recall how to fix.
I would really consider asking in the thread for the process you were following.
If no one gives you any suggestion, you could always try re-flashing the stock image for your phone that matches the highest version you've had installed on your phone. (On fastboot screen you can see bootloader version, so match you stock version to that. see the list of known bootloader versions at -> http://forum.xda-developers.com/moto-x/general/info-warning-risks-downgrading-impacts-t3058202 ) And use mfastboot to flash it (follow option 5 in the 2nd post at -> http://forum.xda-developers.com/moto-x/general/faq-how-to-prepare-ota-update-carriers-t3126425 )

I'm pretty sure I saw this on reddit. You had a mac right?
You need fastboot installed on your mac:
http://forum.xda-developers.com/showthread.php?t=1917237
Assuming you have fastboot working on your mac and your phone this thread method two:
http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
Use fastboot instead of mfastboot for the sytem.img file.
If you receive an error with flashing system you could try:
Code:
fastboot -S 0 flash system system.img

If u can still enter recovery mode, factory data reset from it , if u can't boot still after resetting , u have to flash the full stock ROM.....

Cannot connect to fastboot through ADB

Hi guys. I've had my HTC one for a while now and it had TWRP flashed on it. About a week ago I flashed the android revolution rom, worked well but my camera went really weird if I looked back at some recordings. So I wanted to revert back to stock everything. I flashed a stock recovery for the M7, after that I had the problem of not being able to connect my device to the computer when I fastboot mode. Simply wouldn't pick it up when I typed ADB devices in cmd. My device wouldn't show up after installing stock recovery. And it doesn't want to restore any roms either in stock recovery mode. I can't even access my folders in that mode to flash any roms. I click either apply from sd card, apply from phone storage. Says for a split second check CID failed or something and reboots itself.
I cannot flash TWRP back cause my computer since it can't pick it up. I've tried everything. Changing USB ports, uninstalling my drives for htc. Changing computers, unlocking, relocking bootloader. No result. I'm screwed cause I'm stuck on this android revolution rom, rooted. Just wanna flash custom recovery. I can connect it to my computer, access folders and add things to it but soon as I turn it off and go into fastboot mode it says fastboot usb and can hear the noise when its connected but it doesn't show up in adb devices and when I flash the TWRP it starts send then comes up with FAILED. Help please, would be appreciated!

Adb only works if you'te booted to OS or custom recovery. Command you're looking for in bootloader menu is "fastboot devices"

Fala Puno. Ja sam raditi sada. I'm of Croatian decent in Australia. I'll try this later when I return home

Fixed it! I'm an idiot, I didn't realise I was flashing the m8 twrp instead of m7. That's why it failed. Lol. Anyway thanks

boot loop? soft-brick? HELP!

Hi all,
Any help I can get would be greatly appreciated. I have a Sprint HTC One M7 that was previously rooted. Currently it is relocked with S-On, but at some point an OTA update was downloaded and now my phone keeps restarting itself and boots to this "android is upgrading..." screen. It keeps doing this loop over and over. It restarts itself, and then goes to this "android is upgrading..." I've spent hours in the forum this afternoon and I've tried numerous things and nothing seems to be working. Everything I've tried keeps giving me errors. At this point I would simply like to go back to the stock ROM and have a working phone. Can anyone help?
FYI...
I've tried using the .exe method from an RUU, but that isn't working because when it reboots to bootloader at the very beginning of the process my phone boots to android and I get the "android is upgrading..." message.
I've tried extracting the rom.zip and sideloading it, but I can't sideload because installing the TWRP.img recovery fails every time.
I've tried a factory reset and that fails. Again, I get the "android is upgrading..." loop.
Basically, everything I've done to run RUU fails because my phone reboots to android instead of rebooting to the bootloader, and everything I've tried to work around that problem fails.
I'm currently running 6.23.651.7 and I'm trying to flash 6.23.651.10.
Again, any help would be massively appreciated. I'm desperate...

You can't flash a rom.zip extracted frin a ruu.exe using TWRP, it must be flashed using fastboot with the phone booted in RUU mode.

Holding power and volume down doesn't work? This should get you in bootloader mode. If your phone can't boot to a stable bootloader there is nothing you can do. Once in bootloader there are many options to unbrick your phone.

I first tried flashing the rom.zip using fastboot, but when the phone is supposed to display the HTC logo screen my phone just reboots and goes back to the "android is upgrading..." page.
I can get into bootloader when I hold power and volume down, but I haven't been able to successfully do anything from there. I tried flashing TWRP so that I could attempt to sideload a ROM, but I got an error when flashing TWRP.img.

What is the error when flashing twrp?
fastboot oem rebootRUU doesnt work?

Is your bootloader still relocked? If it is, you can't flash custom recovery. The only thing you can do is run RUU in that state

Well, I was just going to try and do this again, but now my PC can't even find it when I run "fastboot devices." I have the SDK and ADB driver installed, so I don't know why it can't find it all of a sudden.
I can't install the RUU by running the .exe, because when I do and it gets to the "waiting for bootloader..." screen my phone reboots and loads android and goes to the "android is upgrading" screen. So I need to flash the RUU via fastboot, but now my PC isn't recognizing my device in CMD...
Okay... so I finally got adb and fastboot working again. When I run "fastboot oem rebootRUU" the phone reboots to Android and goes to the "android is upgrading..." screen.
Update: So... I was able to successfully use adb and fastboot to unlock my HTC One again. I then tried to flash a custom recovery via fastboot, but I kept getting "FAILED (remote: signature verify fail)". I tried flashing TWRP, CWM, and stock HTC recovery and got the same failed message for each one. I'm just trying to find a way to break this stupid boot loop... HELP!
Update: So, my phone even restarts itself when I boot into safe mode... not good. Can anyone help me out?
