M8 appears bricked no rom or recovery menu - One (M8) Q&A, Help & Troubleshooting

Tried to remove cynagenmod from my htc and return to stock android settings and messed up somewhere along the line, on powering on my phone it loads straight into the boot loader, navigating to >HBOOT then pressing >RECOVERY makes the HTC logo appear for a moment before returning to the first bootloader screen.
[software status modified, re locked, security warning, M8-UL PVT SHIP S-ON]
The rom has been deleted along with recovery, I am not an expert in using fastboot tried using it for a bit and had no success also tried installing htc sync manager to see if it would help but the installer for the sync manager would crash my computer every time (windows 10). Looking for some help as what to do not sure if it can be fixed or should I bin it thanks.

I would RUU if it was me in your position.

To properly troubleshoot where you went wrong, and how to solve it, you will need to describe the exact steps of how you tried to return to stock.
It seems you wiped things in recovery, expecting that to return you to stock? If so, that isn't the case as you now know, without flashing a ROM, TWRP backup, etc.
Similarly, relocking the bootloader renders the phone unable to boot, and wipes the phone; as it expects RUU to be run. But you haven't explained if you were trying to run an RUU, which one, details of your phone version, etc.

[Q] Desire stuck in bootloader loop after hboot downgrade - HELP!!

I have serious problems with my phone that I could really use some help with as at the moment I'm completely screwed - I've already spent hours reading forums but have yet to find advice that will help. Here's whats happened:
I have an A8181 HTC Desire, and I took an OTA update yesterday that bricked my wifi. At this point I thought it would be easiest to root my phone, and after checking that my hboot version was 0.93, I read advice that said to downgrade this to 0.83, which I duly did.
Now, my phone is stuck in a bootloader loop - I get the 3 androids on skatebooards with FASTBOOT in red, and I can choose from:
BOOTLOADER
REBOOT
REBOOT BOOTLOADER
POWER DOWN
If I select bootloader I then get:
FASTBOOT
RECOVERY
CLEAR STORAGE
SIMLOCK
I can access recovery and apply update.zip roms successfully (I've only tried official HTC 2.2 roms as the phone isnt rooted), but after doing so it just goes back to the bootloader loop.
If I select FASTBOOT then I'm just back at the first screen.
I've tried clearing cache and factory reset aswell, but I still can't get past this 2 screen loop.
It's like the bootloader just can't load whatever rom is installed.
Because the phone isn't booting up, I can't use adb or any other pc tools as the device is not detected on my pc - although it does show up in device manager on windows.
I'm close to sending this back to try a warrantly claim, although I'm worried that by trying to fix this I may have invalidated this.
I'd really appreciate any help or advice as to how I can get out of this and get my stock 2.2 back.
Cheers
If your computer using windows, have you installed hboot drivers?
If you have those installed your pc should detect the phone.

You shouldn't have had to downgrade your bootloader. If you can, go back to the newer.
The wifi issue, was widespread on desires, I had it also after a "pushed" update from HTC (european model, unlocked). I downloaded a stock 2.29 froyo. Had to make a gold card also. Took several tries, wipe cache, but eventually successful.
Then, I rooted, and went to CyanogenMod7 rom with clockwork recovery.

[Q] Assistance in recovering

Hi, I have foolishly (possibly?) wiped Android off of my OneX
I was attempting to apply the Tegra tweak and well things went downhill.
I successfully unlocked the bootloader from HTCdev.
I proceeded to apply Interim ClockworkMod to gain root access
This is where things started to go wrong. Any new reboot would only take me to Clockworkmod screen.
I tried http://forum.xda-developers.com/showthread.php?t=1599748
clear cache, davik cache... relocking the bootloader - This results in the device constantly rebooting.
I attempted to apply the RUU ROM's ( from: http://forum.xda-developers.com/showthread.php?t=1543604)
From within ClockworkMod I was then able to:
adb push One_X_1.26.401.2_odexed.zip /sdcard/
Once there I used ClockworkMod to apply an update zip (which I was hoping was the Stock ROM).
A reboot just brought me back to Clockwork.
I then locked the bootloader ( fastboot oem lock. ) hoping it would then proceed to boot as expected.
It didn't just going to HBOOT or an attempted recovery (isometric view of a phone with a green arrowed circle -> RED triangle).
Please someone help, starting to panic a bit. The fact I can upload, the fact that there is some basic interactions should imply this is fixable, but how?
The boot to recovery sounds like you have the same problem that I had.
Perhaps you followed the same incorrect instructions as I did. See here for a solution.

This may help.
with the locked bootloader you will only be able to run a proper ruu so before even attempting the instruction above unlock your bootloader again and proceed from there.
I might start working on some core .IMG files that can be flashed through fastboot to get you going again tomorrow

THANKS!!!
booted back to the lovely ICS desktop
It looks like I did end up flashing RUU since none of the Vodafone branding is present (and it is actually better!)
No idea what went wrong but probably flashed over the boot as hinted at in the other thread.
The provided img files assisted. just need to get this Tegra thing working (not showing up as a running/registered process but thats another story)
Thanks all

[Q][NOOB] Please help me unbrick my PRIMOC

First post here, please excuse my ignorance. This is a Virgin Mobile HTC One V. I never rooted a phone before, and was just trying to do a basic rooting, and somehow got into trouble. I would like to return the phone to stock and start over.
Right now the phone boots itself into bootloader, and shows me this:
Relocked
Security warning
PRIMOC PVT SHIP S-ON RL
HBOOT-1.57.0000
RADIO-1.00.00.0928
eMMC-boot
Jun 18 2012, 10:22:43
I am able to do this: fastboot getvar cid. The response is this: cid: SPCS_002.
I am also able to do this: fastboot devices. The response is this: FA2AKX405758 fastboot.
I have attempted to use this RUU:
RUU_PRIMO_C_ICS_40A_Sprint_WWE_VM_1.08.652.6_Radio_1.00.00.0521_2_NV_VM_3.46_0503_PRL61008_release_262414_signed.exe
It gives me error 170, USB connection error (even though I have installed the HTC drivers). I relocked the phone in an attempt to get that RUU to work, but it didn't help. I also tried to extract the rom.zip from the RUU.exe (by finding it in a temp folder, as described on another XDA thread), but the rom.zip acts corrupt. Various zip programs refuse to open it.
Before relocking the phone (in an attempt to get the RUU to work) I tried this:
fastboot flash boot boot.img
I did that with various boot.img files I found via threads here. This just created various problems. One result was that I was in a bootloop. Another result was that I booted to the screen that said "this build is for development purposes only do not distribute outside of htc without written permission." And it would hang there.
Now my condition is that I boot directly to bootloader.
Starting from the beginning: I unlocked the phone using the unlock bootloader procedure at htcdev. No problem. Then I figured I should do a backup right away, so I installed CM Recovery. Right away I knew I had a problem because it did not run correctly. It would present a menu. Then I would select "backup and restore." It would present a splash screen (with the hat) and just hang there. When I pressed power, it would return to the menu. That's when I started trying various other things.
I never got as far as doing anything with superboot or superuser, which is what I thought I was going to do after doing the backup.
I have read a zillion threads here, and tried various things from those threads, but I'm afraid that without specific help I'm just going to make it worse. I'm pulling my hair out, so I hope someone here can help me while I still have a few left. Thanks!
OK, I have made some progress but I'm still pretty stuck.
I have been able to solve two problems I had before. Before when I ran the RUU, it gave me a USB error. And I could not extract recovery.img from the RUU. I solved both those problems by moving to a different PC.
So now I can run the RUU, and it gives me a bunch of progress messages I didn't see before, but at the end it tells me this:
"Error 155, unknown error. The ROM Update Utility cannot update your Android phone. Please get the correct ROM Update Utility and try again."
So then I tried the procedure described here:
http://forum.xda-developers.com/showpost.php?p=27301573
I unlocked the phone again, and I did this:
fastboot flash recovery recovery_signed.img
I did that using the img file I extracted from the RUU. Then I relocked the bootloader, and I ran the RUU again. But it gave me the exact same error (155).
What should I try next? I notice that the RUU also contains these img files:
system.img
radio.img
boot_signed.img
Should I try flashing those?
Any ideas would be greatly appreciated!
Edit: One more thing. When I ran the RUU, at the end the phone said this:
RUU
Hboot version is older!
Update Fail!
OK, the next thing I tried is the method described here:
http://forum.xda-developers.com/showthread.php?t=1674226
I extracted rom.zip from the RUU, and I renamed it PK76IMG.zip, and I put it on the sdcard, and then I rebooted the phone. The phone found that file and tried to install it, but in the end it gave me the same error message: "Hboot Version is older." On that same screen I see that my current Hboot is 1.57.0000. I guess the RUU contains an older Hboot?
Anyway, that's the same error I get when I run the RUU as an exe.
I notice a couple of people in that thread reported the same problem (Hboot is older), but it's not clear how or if they got around this.
Any ideas?
OK, so here's the next stage in this saga.
Looking around, it seems that there is no RUU for this phone, because I have Hboot 1.57.0000 and radio 1.00.00.0928. I have noticed that people with those specs cannot find a RUU that works, but they have been able to get the phone working with RhythmicRom. I see that discussed here:
http://forum.xda-developers.com/showthread.php?t=2147407
So what I'm trying to do now is install RhythmicRom, but I'm having trouble doing that, I guess because I don't have CM Recovery installed, so the standard recovery is running instead.
I have placed RhythmicRom_v1.4.zip on my sdcard. I am able to boot into bootloader, and I have done factory reset. In the bootloader, I can select Recovery and I see a screen that indicates the phone is looking for something (green circle containing green arrow pointing down, and with a progress bar at the bottom, and an icon of an sdcard). But I guess it doesn't find what it's looking for, and then I see the screen with the red triangle/exclamation mark.
I'm thinking that maybe it will work if on the sdcard I rename RhythmicRom_v1.4.zip to whatever the phone is looking for. Maybe I should rename it to PK76IMG.zip? Just a guess.
Many thanks in advance.
OK, that sort of almost worked. On the sdcard, I renamed RhythmicRom_v1.4.zip to PK76IMG.zip. I booted into bootloader, and it looked like the phone found that file, and loaded it. Then I did this:
fastboot flash boot boot.img
With the boot.img that was inside RhythmicRom_v1.4.zip. Then I rebooted. Now the phone gets to the red animated Virgin Mobile splash screen with the annoying audio. That seems like a good sign, since I haven't seen that in a while. But instead of continuing to boot, then I see the white HTC screen that says "this build is for development purposes only do not distribute outside of htc without written permission." And then it continues to loop between those two screens, so I am stuck in a bootloop. Although I found I was able to interrupt it and get back to the bootloader.
Not sure what to try next. Any suggestions?
Wow, I can't believe you haven't had a single reply.
Ok. First of all.... Use TeamWinRecoveryProject
( TWRP ) as your recovery img
So easy to use
Use fastboot the flash
fastboot flash recovery recovery.img
Then boot into your new touch screen recovery
Now click wipe
Cashe,Dalvick,Factory Reset, System
In that order. It makes sure every thing is wiped thoroughly.
Now navigate to where the Rom is you would like to use and flash it in recovery.
After It's flashed click the wipe cashe/dalvick
Then click home,reboot,bootloader.
Once in bootloader, flash the kernel/bootimg
fastboot flash boot boot.img
After the boot.img is finished,
fastboot reboot
Victory and enjoy the awesomeness of custom ROMs!
P.S. don't forget to unlock your bootloader again. First and foremost
fastboot flash unlocktoken Unlock_code.bin
Russell, thank you for your response. After 24 hours with over 100 views and zero replies, I figured that meant that I had already done the proper steps, and there wasn't some obvious solution I was missing. Although I can see now that I should have tried TWRP. It couldn't have made things worse, and maybe it would have worked better for me than CM Recovery (which seemed to fail as soon as I installed it).
Another key thing was when I figured out that there is no RUU for my specs (because there was an OTA that installed a newer hboot and radio). I like the idea of trying different custom ROMs, but I don't like the idea of never being able to go back to stock, since I would expect that all the custom ROMs have some quirks that I might find unacceptable. But I notice that you have the same hboot and radio, and I assume you have a backup of your stock ROM, so maybe you could have helped me with that.
Anyway, at literally the exact moment that you were posting your comment, I was standing at the UPS counter handing them the phone. If the phone had been working, we would have heard it buzzing inside the box as your email came in! The phone is heading to the HTC repair facility in Houston. They told me they would unbrick it for me for less than $35. I haven't seen anyone else report this, so maybe I was misled and it's too good to be true? We'll see. I don't like being without the phone for a week, but $35 seems like a cheap price to clean up the mess I made.
Anyway, thanks again for speaking up.
Check out the CDMA development thread

Good luck
I see the thread you're talking about. I just did the download (might as well have it handy). Thank you.
Hope it helped or helps in some way

Similar problem
Hi,
I had a similar problem. Following this thread I have successfully "unbricked" my phone. My main concern though is activating my phone on VM, which I'm unable to do as I can't go back to stock. I bought the phone as is from craigslist. Any suggestions?
Edit: Internet seems to work though. No go on phone calls or texts, when trying to call this is what I get(Audio):"Account couldn't be verified"
Visit the HTC one v CDMA thread I have a stock rooted Rom there for the taking

[Q] HTC One M8 can't upgrade firmware

Hi, I've just bought a HTC One M8 from craigslist and I have a problem or two. The phone cannot connect to google servers, but the posts I found to fix that didn't help (delete hosts, install gmail). The main problem is I can't get it back to stock to get the new firmware (it's on 4.4.3), which I thought may cure my problems.
The phone is on Venom ROM, carrier is T-Mobile USA, tampered and unlocked flags showing, S-On
Here's what happens when I try to flash a recovery image:
adt and fastboot do exactly what they are supposed to do, but when I hit "Recovery" on the phone it says 'entering recovery', then just boots up as normal. I never get to TWRP. If I use CWM, it says 'entering recovery', then goes back to fastboot.
For some reason, the phone is taking a good 60 seconds to boot up each time.
I have tried to go to S-Off, but I got the Firewater message:
*** whelp, this sucks, firewater can not work on your device *** (etc.)
Can you tell me how to get communication to Google working again, or how to upgrade the firmware?
Thanks for your help, I am new to this, and running out of ideas
Alex
I would say use fastboot to install TWRP and try again. Or use fastboot to install the stock bootloader and then try to flash an RUU. Google around this forum for instructions.
like FreydNot said, I'd try downloading and fastbooting the latest TWRP onto the phone. power it down and let it chill for a minute and then try to get into the recovery.

Verizon HTC One M8 stuck at HTC logo screen, no recovery or OS to be seen.

Hello All,
I am looking for some advice to get my phone working again.
I have a modified bootloader and S-Off.
When choose the recovery option in the bootloader it goes back to HBOOT after showing a brief android screen that mentions something about a development build. The phone does try to boot but gets stuck on the HTC logo screen. From what I can tell I have no OS installed and no longer have a recovery. I am also unable to get abd working since i cant enable usb debugging etc.
Any tips?
Thanks,
Matt
Were you doing something to the phone that led to this condition? If so, list those steps in as much detail as possible.

ADB only works within the Android operating system, however, as you noted, you have no OS. Instead, what you need is fastboot - which, if you can get HBOOT to come up, you have. There are several "kits" with fastboot versions, or you can download the full SDK, which will have it. It is similar to ADB, but operates at the bootloader level instead.
1) Since you are S-off, and presumably bootloader unlocked, just flash a new recovery from fastboot. From there, install a new ROM/nandroid from your SD card.
2) If you aren't bootloader unlocked, boot (rather than install) TWRP, and use the ADB bridge mode to manually reset the lock state using Scotty's thread. Then go back to #1
3) Or, if you haven't altered your CID/MID, just re-run an RUU and put it all back to a known state. (assuming there is an RUU for your CID/MID)
These aren't detailed instructions, but there are several threads relating to each tip in the forum.
