[Q] Bricked Sprint HTC One M7 - Stuck in boot loop

Hello,
About a month back I destroyed my old HTC One. I unlocked the phone and flashed a new rom for the International version instead of the Sprint version. Ever since, no matter what rom I use, the phone is stuck in a boot loop. I cannot set it back to factory with the RUU because my version is more recent and I do not have S-OFF. I've since bought a new phone, but I'm looking to attempt to get the old one working. This has been a learning experience.

Any insight on what I can do to fix this would be greatly appreciated.
Thanks,

Hello I have a problem,

You bootlooped because you loaded an incompatible kernel. Use *only* m7spr/m7wls kernels.
With that said -- just download a ROM you want (again -- stock with M7SPR or M7WLS (they're the same thing, just different ROMs call them by various names -- not going to explain that here).
Then, load your recovery (hopefully my TWRP 2.8.0.3 because it will work for you); "adb push" the rom file to /sdcard (i.e.: adb push <path_to_the_zip>.zip /sdcard) -- yes, that will work in recoveries.
Then install the ROM in your recovery. You should be fine with the caveat that if the kernel you loaded messed up your partitions (by writing it to the entirely incorrect disk partition), you'll have to RUU back to stock.

[Q] Recommend appropriate RUU to install stock ROM for HTC One

Hello,
I'm using HTC One which was initially locked by 3 network (UK) and i got it unlocked last month. I have unlocked my boot-loader and rooted my phone recently. My phone got updated to android version 4.3, after the upgrade i tried performing S-OFF using REVONE but i was not able to S-OFF my device. To install a custom ROM i have to be S-OFF. I have to revert back to stock android version. Could anybody please suggest me which version of RUU should i use to install stock ROM to my device?
I have HBOOT version 1.55.0000
I don't know what is it but when i start my device in boot-loader mode these are all the information i could find:

1- relocking was not the wisest decision, better unlock again
2- to install custom rom, you only need unlocked bootloader and custom recovery. S-Off is NOT needed
3- to get s-off on hboot 1.55, use http://rumrunner.us/ (with compatible ROM, I think ARHD 31.6 should work: http://forum.xda-developers.com/showthread.php?t=2183023)

use latest TWRP (2.6.3.3 or above), i believe CWM hasn't been updated for 4.4 ROMs yet: http://forum.xda-developers.com/showthread.php?t=2173870
verify MD5 of twrp before flashing!!

TWRP should work, maybe need to format. I always use the HTC One Developer Edition RUU zip that can be found on HTC Dev site as well as the numerous threads around XDA.

[Q] Unroot Sprint HTC One from CM11

UNLOCKED
HBOOT 1.56
Radio 1.00.20.1108
OS 4.06.651.9

I need to restore my phone to a version of stock android (either an actual stock RUU or Android Revolution or whatever) so that I can get to the UICC option to turn off my SIM card (this setting is not available in CyanogenMod apparently).
Because I am on a newer firmware and because I am S-ON I do not seem to be able to install any of the (mostly older) RUUs I have found. Any suggestions? Is there an RUU for 4.06.651.9 that I am not seeing? Is there another way to roll back my OS to allow an older RUU to be installed? Another option altogether? A way to S-OFF while on CM?
Thanks for your help

you can use this then take the OTA updates
http://www.htc1guru.com/dld/guru_reset_m7_sprint_3-04-651-2-zip/

Is this the 3.04.651.2 RUU? If so, I already have a copy, and when I attempt to run the ARUwizard I get Error 155. Most likely I am doing something wrong. I just assumed that since I am already on 4.06.651.9 that the problem was I couldn't install the older 3.04.651.2 version. Thoughts?

This is exactly the same issue I'm experiencing. Well, now I'm even beyond this point... I am only able to boot the phone to the bootloader.
Edit: I am relocked as I am S-ON. I can't update firmware as the signature check fails. Flashing the 3.04.651.2 zip has a signature verify fail, as well.

Hope this helps

If you can still boot to bootloader your phone is fine. You should still have recovery (TWRP?) on your phone I assume. Regardless here are some steps that should help:
1. Figure out if you are S-ON (is found on the bootloader screen)
2. If you are S-ON, try Rumrunner to get S-OFF (just google it). This will allow you to install any RUU regardless of your firmware.
3. If Rumrunner doesn't work or you don't want to go to S-OFF then download the 4.06 RUU here http://forum.xda-developers.com/showthread.php?t=2658910
The problem is your firmware is ahead of the corresponding firmware of the 3.X release. As such you have to install from the newer RUU.

Actually, it seems that the phone is wiped; I can't boot my recovery. As a result, I can't really get S-OFF. I'll try the 4.06 RUU, but would it make a difference that it's .4 and not .9?
EDIT: I'm talking out of my ass right now. Long day, and this isn't helping. I am figuring it out; unlocked the bootloader, and now things seem to be functional. Well, except CM doesn't seem to want to boot any longer, but that shouldn't matter for long.
EDIT 2: How can I get S-OFF without enabling debugging? As of right now, CM is just in a boot loop.

Sim Unlock Sprint HTC One Max
I almost cannot believe how many different ROMs I've tried to flash after wiping out my original ROM.
Bootloader unlocked and rooted I managaged to relock the bootloader while trying to fastboot flash a stock ROM, which also failed.
Beleive it or not, I've have found a couple that will boot up with my Sprint HTC One Max . I was able to re-unlock the bootloader, flash a new rom and even recover user data I had backed up to my PC via adb backup.
All this for not, as I still cannot find a Sense ROM that will flash on my device and allow me to unnlock the Sim via Sim Unlock Helper.
Any help would be greatly appreciated!!!

[Q] Questions about hboot version, Kernel, and Firmware

Hello,
I have just been given a rooted HTC M7 (AT&T). It hasn't been used for almost a year, but it seems to work. It only has a recovery on it, not a ROM. I have no idea how to get it from where it is up to the latest and greatest. Any help or recommendations would be appreciated. I tried to read up on everything, but i couldn't parse out the info I needed from existing threads. I hope my terminology is correct!
Here's what I've got:
Device: AT&T HTC One M7

*** Unlocked ***

May 3 2013, 19:16:59: -1
RECOVERY Info:
TWRP 2.8.1.0
ROM INFO:
I have not loaded a rom onto the device at this point. I haven't felt comfortable since I don't know if the phone in its current state will run the latest roms.
Here's what I need to know.
1. Do I need to update my bootloader? It seems like 1.44 is much older than what other people are currently using. I've seen most people on 1.57 or 1.56. If I do need to update it, what version should I update to?
2. My recovery seems to be almost up to date. I am pretty sure i know how to get the .zip for the latest version, but I don't know if I have to flash it or use another way to install it.
3. I cannot get fastboot working on my windows 8.1 machine. It does work on an old windows 7 laptop I have. It seems like others have this issue on hboot 1.44. Is there any fix for it?
4. Firmware, Kernals, and Radios. How do you know what firmware, kernel, and radio to use for a given device? does it depend on the rom you choose? There seems to be so many and it isn't clear to me.
5. Does it matter if i choose a GPE rom, a Cyanogen Rom, or a Sense Rom? Do kernels, firmwares, and radios depend on the type of rom I choose?
Thanks for all your help! I look forward to using my new to me device.

you have an AT&T Phone with s-off. Start updating with this RUU from windows 7
http://dl3.htc.com/application/RUU_...13_10.38j.1157.04_release_334235_signed_2.exe
After this RUU windows 8 will see your phone again
Then this Firmware > http://fs1.d-h.st/download/00101/a1w/4.18.502.7 Custom Firmware.zip
followed by this RUU >> http://www.androidruu.com/getdownlo...09_10.26.1718.01L_release_356565_signed_2.exe
To flash the Firmware use
fastboot oem rebootRUU
fastboot flash zip firmware.zip
fastboot flash zip firmware.zip
fastboot reboot-bootloader
when your done check for software updates in settings before you flash a custom recovery and root.
you should get the 5.x.502 OTA update

Amazing. Thank you so much.

Why you told him to 1st flash ruu then firmware then higher ruu
Why not higher firmware or ruu directly ?

because a lot of people have problem flashing the 4.x RUU alone, they get a error 155 .. flashing the firmware first solves this problem
And the 3.x Full RUU insures he does not get any problem upgrading from hboot 1.44
so he in fact went the same route AT&T released the updates

How come Android Revolution ROMs keep putting my phone into a bootloop? It makes my phone boot into TWRP Recovery. I have tried both Android Revolution HD 90.1 ( (Android 5.0.2 Lollipop + HTC Sense 6.0) and the stock HTC system dump (Android 5.0.2 + HTC Sense 6.0 | Latest: 7.15.401.1) without success. I just want to know why!

If you flash in twrp you need to flash the boot.img in fastboot in order to boot because your s-on. And also what you are running I believe are gsm based roms. In which case they will never boot.

ARHD is not compatible with Sprint.
By flashing it your partitions are messed up now.
You will need to RUU to fix and stay in the Sprint section when choosing a rom.

Yep says it several times in the OP.

I can't seem to get any other ROM to boot except CyanogenMod and LiquidSmooth. CM is completely stable while the latest version of LS is a bit buggy. They both absolutely refuse to acceept any APN settings. I am using Ting's service right now and I can't use it on these ROMs.... I tried flashing several stock Sprint ROMs for the HTC Onr M7 and none of them will boot. They'll boot if I flash the boot.img like someone here suggested but it doesn't help. It will go to the desktop, however, the screen is completely black. Is there anyway to flash a stock ROM properly? RUU's don't work either.

My HTC One is CDMA (Sprint).
First try updating by going to Settings ---> About ---> Software Updates. If that doesn't work try the following:
This Lollipop update process is ONLY for the Sprint HTC One M7.
First flash the firmware via Fastboot: 6.16.651.2_firmware.zip >>> https://www.androidfilehost.com/?fid=95916177934523626
And then install the RUU for 6.16.651.2 via Bootloader RUU Menu:

If you don't know how to do these things, then you shouldn't attempt to. You could end up hard-bricking your phone.

Hello again,
I have some experience using fastboot. The thing is that my HTC M7 originally was Sprint CDMA but the person I bought it from he assured me that he unlocked the GSM.

I guess my HTC M7 is similiar to yours, but I want to be sure before flashing it. I have a backup already just in case.
Thanks a lot.

Your phone is for sprint as it says m7wls you can use gsm service perhaps since you say its unlocked meaning Sim unlock always look for Roms that are m7spr or M7wls based I also suggest s-off so you don't have any complications with flashing

Awesome! I'll make sure to re-read the roms/RUU's specifications prior to install any.
Thanks a lot guys.

It has been a little bit difficult to S-off my HTC, since it has Hboot 1.57. So far I've tried Revone and Rum Runner without success.
Firewater seems to be down and I'm tempted to pay for SunShine, but I'm not really sure about paying for an application that might not work.
My HTC originally came with Android 4.4.2 and I got a notification to upgrade to lollipop via OTA, but I was suggested to make a backup just in case. So I had to root my phone, unlocked the bootloader and installed TWRP in order to get my system backup, but due to the previous procedures I can no longer upgrade to lollipop.
Right now all I want is to follow my original plan by installing a stock rom and try to update to lollipop via OTA.
You kindly suggested me to s-off my cellphone, but I've seen some videos on youtube in which they install stock roms with s-on:

If Sunshine won't work you won't have to pay.

Do you mean flashing firmware.zip with these commands?:
Fastboot oem rebootRUU
Fastboot flash zip firmware.zip
Fastboot reboot-bootloader

I'm counfused, I thought that both (firmware and RUU.zip), should be flashed via fastboot. Am I missing something?
Thank you in advance.

Never mind guys
Finally I upgraded my HTC to Lollipop.
I freaked out because it didn't boot up after flashing RUU.zip
I decided to go out for dinner and come back and try as many times as needed. Fortunately I realized that I misspelled the command fastboot reboot-bootloader I had forgotten to type the hyphen. Then I reinstalled the drivers, rebooted my pc, tried another usb port and used the RUU.exe. Now my HTC M7 seems to be working perfectly
Thank you very much guys.
