Did I just brick my Hero? Help!

Some basic info about my phone-
HBOOT 1.47.0000
Radio 2.42.01.04.23
Carrier- iWireless (Kroger, Sprint subsidary)
S-ON
Alright, so I was just using my phone as normal. Running CM7.2 and ClockWorkMod Recovery. I turned off my phone, everything was fine. When I went to turn it on again, it showed the green HTC logo, as per normal, then it suddenly rebooted. There, it showed the green HTC logo again, and it'll just stay there. So I tried to boot into recovery (pulled the battery, put it back in, held the red end call button + volume down, got into hboot, then pressed home to go to recovery).
The thing is- it did the same thing. Reboot before it gets to recovery, and then stuck at the HTC Logo. I tried using the Sprint RUU, didn't work- it told me to download the right RUU for this phone, and gives me an error 131. I used the flashable RUU found in this thread (found here), in conjunction with this tutorial (found here). It gave me an error that looked like this when I ran "fastboot flash zip *flashable RUU zip path*"
Code:
FAILED (remote: 42 custom id check fail)
I believe it has something to do with the fact that it is NOT a Sprint branded phone. It doesn't even have a Google logo on the back.
Since it's not S-OFF, I can't flash a recovery via fastboot. I'm stuck. Help?
*TO CLARIFY*
I can't get into Recovery, or the actual system. I also can't access adb. The only part I can access is the bootloader and fastboot.

How much battery did you have left before you turned your phone off ?? Also what was the reason you turned your phone off ??? Also you linked to the use fastboot thread did you already type the "fastboot reboot reboot RUU" command ??

About 75% if I remember correctly. Only light usage. And I just turned it off in school, we were taking a test. Nothing abnormal about turning it off. And yes, several times. Tried flashing recovery/system/boot in every way possible, using that command and not using that command. I noticed something else- it seems like the NAND memory is completely wiped. There is NOTHING on the phone, other than the bootloader.

After you ran that command you tried to flash a zip or no ??? And more info on when you say the bootloader is the only thing on the phone would be appreciated. Also when you plug your phone into your pc does it recognize in its current state ??? Also when you boot into the bootloader what info is now displayed ???

Yes, I tried flashing multiple times. As I said, it fails with a CID check failure. And it doesn't seem that there's anything on the NAND anymore, as it doesn't even get to the boot logo, and recovery will just restart the phone.
My PC recognizes my phone, only in fastboot. And just normal bootloader info- model number, baseband, etc.

Phone has no O/S installed, cannot detect phone to put rom zip on phone. please help

I believe I overwiped my phone, it has no rom on it now, and when I plug it into the computer, it makes the noise, but will not show up in windows explorer. I am able to boot into recovery, TRWN, although I can't do anything from there because I have no rom to install. I have tried installing the latest HTC drivers, using a different cord, disabling antivirus, pretty much everything previously listed in these forums. Is there a way to use the command prompt to send a rom over to the phone? Please help.

donwload the all in one toolkit use it to erase cache then install recovery. after that either mount usb otg and copy rom to sd or sideload a rom. all in one toolkit automates everything you need to do:good::good:

I wish I could say that worked, however when I try to use the AIO toolkit, when it launces the command prompt it says 'device not found.' same problem as windows. There has to be a way to force a file on there. Any ideas? Again, I can boot to recovery but have no zip on the phone memory to flash.

if it says device not found press the power button once and try again. it will say once in fastboot close the first window if you close the first window and nothing happens then press power and it should start
if your in fastboot options should be----bootloader----reboot----reboot bootloader----power down

Thanks for getting me this far. Mounting didn't work, so I sideloaded rom. it is showing up on the phone as "sideload.zip" i try to run and it fails. Any ideas?

Have you used this command?
Code:
adb sideload /path/to/rom.zip
If yes, it will work.
Maybe sideload.zip contains rom and if sideload.zip don't have meta-inf it will not flashed

I get it sideloaded and installed android revolution. however, when I'm done installing the rom, trwn tells me "superuser is not installed, would you like to install now?" I say yes and then the phone goes blank, and reboots to bootloader. Any ideas?

OK, so I didn't say yes to the question this time after sideloading android revolution. same thing. goes blank then reboots to bootloader menu. So I tried sideloading viperrom 1.04. This time after it finished sideloading it randomly installed instelfl, and now viperrom is installed, its booting up to the phone now finally, yet before anything can initialize, it just reboots again. It's been caught in this boot loop about ten minutes now. No end in sight. Any ideas?

ViperRom from Sprint or AT&T one forum?
Your phone is branded or no-brand?
However, boot into recovery, and use this command:
Code:
adb push name_of_rom.zip /sdcard
, then flash it

Also, I have now tried flashing and installing TrickDroid which also boots to the O/S but then after a few seconds reboots and starts all over again. I just let it run, and it boots, then reboots, over, and over, and over again. Any ideas?

Have you tried to flash the boot.img from fastboot?

I fixed it!!! I had to download the latest RUU for the HTC One. I ran the RUU after relocking, and then started the root process from scratch. RUU is the only thing that would work. Also, the best rom I have gotten to work for sprint is ViperRom, TrickDroid installed and booted but the camera wouldnt work. Thanks for the help and suggestions!

Reflash the latest TWRP and check if adb work.
Becuase without it you can't push/sideload a rom...

Can't detect SD Card

Hi, I'm having sort of the same problem. My phone is stuck on a bootloop, I flashed a new recovery because the previous TWRP stopped working. When I try to wipe data/factory reset, It says that it can't detect E:\ or the SD Card. I can't even mount it. Any ideas? Please help. Thanks

[Q] Boot Loop D:

Hello friends, I'm new here. The name's Jay. I hope to make good acquaintances here
Now for my problem: my One is stuck on a boot loop. It boots fine into the bootloader and recovery. I tried using the 1.29 RUU and the latest RUU (version 3.x) but still after a few mintues of booting into the OS it would restart. I've tried factory reseting and wiping the caches but no cigar.
Some back story: I originally had the phone rooted but with stock ROM and bootloader (using CWM recovery). All was good until one day my phone was not getting any service (there was an x on the signal indicator). I tried restarting my phone and thats when the boot loop started. I, ofcourse, backed everything up via adb (so no problem there) then tried resseting, changing ROMs (cyannagem) and it still rebooted a few minutes after the OS loads. On the sprint ROM, it always says system is unresponsive and it crashes.
Is my phone dead for good?

Which os were you on? Did your father get 4.3 update?
Hboot version?
Does ruu go through completely. If not check drivers

IWhen i brought the phone (July 2013) HBOOT was on 1.4x (something close) and i think 4.2.2 android. That rooted fine, until i had the boot problem. After trying the latest RUU 3.x (and it did go through all the way both the 1.29 ruu and 3.x) HBOOT is now at 1.5x and android is (i think) at 4.3 (it doesn't stay on lopng enough for me to check the andoid version).

Boot into Bootloader mode by using power button and volume down key.
Install drivers for HTC one on a different computer. HTC should show as MyHTC in device manager.
Then close all other programs on the computer and run 3.04.651.2 RUU from here
Good Luck.

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 !

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...

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?

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?
