[Q] Sprint HTC One Bricked

So, I was trying to put the Google Edition rom on my HTC One for Sprint. I had the right rom and everything. I noticed Wi-Fi wasn't working so I took it off and tried to go back to stock and then I noticed that the version on my phone (1.31.651.2) was higher than the version on the RUU. I have no OS installed on my phone and every time I try to flash a rom, it tells me I'm unrooted. Then, when I'm prompted to install superuser, it just reboots. I am now stuck in bootloader and recovery. I have absolutely no clue what to do. I have S-on as well. Please help!

All I can think of is to use this stock ROM here based on the 1.31 firmware and use the adb flash method. But I'm not sure if that would work as flashing .img's from adb would require S-OFF. Then again I am a bit new here, and others with more experience could chip in and then I may learn from it as well.

From bootloader use this tool to sideload a rom. (download the rom you want).

Also after doing that you can follow this http://forum.xda-developers.com/showthread.php?t=2390821 to use the 1.29 RUU if needed.

I just tried to use the program but it always says error: closed. Also, in recovery, it doesn't let me open sideload. It always fails. Again, whenever I try to flash a rom, it tells me I'm not rooted and it fails to install. There is really no RUU for version 1.31.651.2? I've been without my One for over a week :'( I'm going nuts lol

You need to s off. You get a lot more options for recovering from things like this. The thread is in one of the development forums here. Use moonshines method or download the all in one tool and use revone. It's really easy. Then you should be able to RUU back to stock and reroot.

I want to thank you guys for helping me first and foremost but I could not get revone on my phone and I couldn't do moonshine either. Moonshine ended in an error and revone requires root which somehow I don't have. I don't think there is any way I can get s-off

If its not done can you use the all in one tool to dev unlock and flash a recovery. Then you could either sideload a rom or try this method to RUU back to 1.29 http://forum.xda-developers.com/showthread.php?t=2390821

Whenever I try to sideload to use revone, it fails and tells me to reboot. Trying to flash superuser or any type of rom also fails. I'm somehow unrooted, and when I try to use the command prompts to get S-off, when I put in the "echo.." command, it says there's is an error

From recovery try to perform restore..it should work instead of rebooting.
Or u cn go back to stock firmware d base version of it
Nd do double check that it supports ur device model.
Good luck n keep posted.

Ok so you need to do the following
Dev Unlock http://www.htcdev.com/bootloader/
Then Flash a recovery with this tool.
http://forum.xda-developers.com/showthread.php?t=2236814
Try a rom like the following based on 1.31 and sideload with above tool.

If you follow this you should have no trouble getting back up and running. If you do use the RUU then maybe also follow my guide and get s-off to avoid future problems.

Still nothing Sideload failed so I used adb push to get the rom and try to flash it that way but that failed too.

Does the computer see your device? Adb? Fastboot? Is TWRP installed?

I have no clue how to do it, though. I used adb push to get superuser on my phone and when I try to install it, it fails. I'm not sure if I'm pushing it to the wrong folder or what. How would you be rooting it?

Try sideloading through TWRP a stock rooted Rom
Sent from my HTCONE using xda premium

So I recently accidentally wiped my internal storage which pretty much bricked my phone. I was rooted with S=on and custom recovery. Sideloading would not work for me, tried using TWRP and Clockwork mod recovery. I was able to return to stock though using this method : http://forum.xda-developers.com/showthread.php?t=2250904. Worked like a charm, then I unlocked the bootloader again, flashed a custom recovery again and rooted again. I didn't see anyone else post the above thread, so I thought I would share in the hope that it helps.

[Q] I hope I have't bricked my Sprint HTC One

It all started when I rebooted my phone one day. My phone loaded up the lock screen with google voice. I could say the pin but could never get my phone unlocked. The keyboard button didn't work. So rather than just bootloader/factory resetting my phone, i decided i might as well unlock it and give myself root and flash a rom and try it out. I am an experienced EVO 4G user and have flashed many a rom. I did not have any problems unlocking the phone, flashing the TWRP recovery, applying su, or flashing the rom. I flashed the rootbox rom. It worked just fine. I then decided I was going to try a different rom out. I was not aware that there were roms that would cause problems... the non-sprint roms. I then tried to flash several non-sprint roms. None of the worked and eventually my phone would only boot up into the bootloader. I was able to successfully fastboot flash the TWRP recovery back onto my phone. I tried then to load in a sprint rom. Apparently I had messed up my radios, file structure and possibly other stuff, as no rom would work at that point. After much research, I found I needed to apply the RUU to get my phone back into "sprint" mode with the correct radios and file structure. I have been trying for hours now to do just that. I have tried all the methods listed on xda. The current condition of my phone: Will boot only into bootloader, will not boot into recovery although i think the TWRP recovery is still on my phone. I have the tampered, relocked, and security warning messages at the top of my phone. I am still s-on. I cannot get s-off as I have no accessible os on the phone to use the adb commands. I do have fastboot access. I have tried to fastboot flash the ruu and I get failed messages either <remote: 12 signature verify fail> or <remote: 43 main version check fail>
Any/All advice recommendations are welcome. If there is a thread about fixing bricked phones or tools to load RUU, I have tried them to no avail.
Thanks

Have you tried running the RUU from your PC? It would also help to know if you are on 1.29 or 1.31.

I am on 1.31. I have tried running the RUU from my PC and I got error 140. I tried looking that up and could not find any solutions to that. I figured it was because I am on 1.31 and not 1.29 and I still had s-on. That is when I tried to get s-off so that I could apply the 1.29. Is it possible to open a fastboot shell? I was going to try to push the revone files to the phone via fastboot and then run the commands via fastboot, but didn't get around to trying that out last night.

Congrats on getting phone back up. I recommend you stay away from flashing Roms that are not for Sprint but I think you learned that part first hand already.

Yeah, I sure did. Coming from an OG EVO 4G that was a little bit of a nasty surprise. Wel my phone is sitting on the fastboot screen after the successful ruu. The only message at the top is **relocked***
Can i boot like normal now? Should i flash a rom at this point? i'm kinda still wearing the kid gloves...

We did not get to s-off. I am still s-on. the way I understand it is that basically I am back at square one... only I can use the fastboot command to unlock the bootloader, I don't need to go to the HTC website. and once i put a recovery on i can load any SPRINT ROM i want.
i'll do my best to be good this time

[Q] Unlocking bootloader

Hi all! First of all I'm sorry if this has been asked previously but after 3 hours of searching I was unable to find a straight answer and I have tenths of bookmarks opened...
Right so, just got my "new" (used) phone delivered today. 6 months old, currently running stock 4.4.2 with Sense 6.0 under the GiffGaff network. Straight away I went and tried to flash a new ROM onto it (flashed a few roms previously to my HTC Sensation with no problems). So just the usual routine: fastboot > HTCdev > get token ... and here where the first problem occurred. I couldn't get the token as I was getting the following error:
(bootloader) [ERR] Command error !!!
OKAY [ 0.010s]
finished. total time: 0.010s​Restarting the phone/PC didn't help, changing USB debug on/off also didn't help. Fastboot unlock oem command didn't work either as it gave me the same error. So I went and downloaded the Hasoon2000's AIO tool to see if that will work but again no luck. When hitting the "Get Token ID" I get an error that the phone is offline - . - . So I had a little search on the net and found out that maybe it's due to my HBOOT version which is 1.57 and is S-ON . However I have no idea how to change that nor if it'll actually solve my problem and I don't want to do anything outside the box so that I don't get my phone bricked.
Any ideas what might be wrong/what am I doing wrong/solutions? I'm clueless at the moment and about to run out of patience... Any help is more then welcome

Hasoon2000 did a great job with his toolkit, but I recommend (and many others) not using toolkits. use fasboot and adb directly from the command window, much better when you are trying to find what doesnt work. Be sure to have the latest sdk on your computer, and latest htc drivers. Also make sure to use 2.0 usb ports, not 3.0

Thanks for the reply mate. I watched the video again but I had no luck. However, thanks to that video I went and downloaded the huge SDK archive from HTC site. Instead of using the small archive with "essential" files for the adb, I used the one from HTC site (it has many more files in adb folder) and guess what, it worked! Now, I'm very happy that I finally unlocked it but my question now is, why didn't it work with just the "essential" files? All tutorials videos/forum posts etc. mentioned just the 4 files and not the big HTC package so if it wasn't for the fact that I was desperate I don't think I would of ever unlock this biatch...

Right, instead of creating a new thread I'm just going to ask here. So I successfully unlocked the device and using this video I tried to root the phone. Everything went smoothly, all successful and so on. However when I downloaded the root checker it gives me a message saying the the device is not properly rooted . I then tried with firewater s-off but no luck here either. I've attached the image of how my cmd looks when trying the firewater method. I really thought it's going to be a bit easier to flash this phone... Any advice here guys?
Edit: I just realised that the phone is still S-ON...how did this happen even tho I successfully installed everything that's required...?
Edit2: Tried the temp-root method with firewater but even this doesn't work. I'm getting an error and fail messages (image attached). I think I've run out of ideas here :/

first, why are you trying to s-off? s-off is not required to flash custom roms (except for GPE roms), only an unlocked bootloader and a custom recovery (twrp 2.6.3.3) are needed. You definitively need a fully rooted phone to use firewater and an unsecured kernel would also help. Btw almost all custom roms out here are pre-rooted, so just flash a rom and you'll be fine.
and that video you have linked is very outdated, twrp 2.5.0.0 lol. just flash twrp 2.6.3.3 and then boot in recovery. Quit the recovery and you'll be prompted to install root.
but anyway, is your goal is to flash a custom rom, you don't need to root before, they are all (almost) pre-rooted.

Make a backup using TWRP first..
Also the file you should have used should be SuperSU-2.02.. but if you are going to flash a new rom, point is moot.

[Q] Changing Sprint to International version

You can't really change a Sprint device into a different variant. Only a Sprint-compatible kernel will boot on the Sprint variant, and network connectivity will only work with Sprint firmware installed. So really, the answer is no.

Updating is easy - just run the latest RUU. It'll wipe your data, but it'll give you a nice clean start. The device should remain unlocked. You can even leave the stock recovery intact after that and just fastboot boot TWRP to install SuperSU for root. That'll allow you to take future OTA updates (as long as you don't change anything on /system).

Ok, I'm new into this so, please would you explain me the RUU part and which is the latest RUU and the fastboot TWRP part? Or if there's any tutorial you could show me, that would be cool.
I hope I'm not bothering you with my doubts but I just want to learn.
Once again, thanks for the support.

Connect your phone and PC and double-click the RUU file to start the installation process.

Thanks a lot, I'm now running lollipop on my M8, using the ruu, I lost root access though, now what is that Fastboot TWRP CaptainThrowback mentioned? Will that get me root access again? Is this what I have to do?

Fastboot Install Method (No Root Required):
You will need the platform-tools from the Android SDK on your computer. Find the SDK Only section on the page linked and install the SDK and download only the platform-tools to get adb and fastboot binaries.
Windows users will need proper drivers installed on your computer. You can try the Naked ADB drivers or the Universal ADB drivers if you don't already have a working driver installed
On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:
adb reboot bootloader
You should now be in fastboot mode. Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:
fastboot flash recovery twrp.img
fastboot reboot
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

I have read that changing CID to SuperCID helps in installing different carrier roms in to a particular carrier phone,, Can you please explain me this ? Thanks!

[Q] (Q) can you help with 5.05.651.2 RUU flashable zip?

I flashed a gsm rom on my sprint m7, which put it into a bootloop....
I tried the firmware fix , but ended up with signature failures.
I haven't been able to get the RUU.exe to run on my windows 8 machine.
Wondering if anyone can supply me with 5.05.651.02RUU flashable zip?
I've searched, and see a bunch of flashable firmwares, but non for 5.05.651.02.
Or maybe a solution to my ruu.exe problem? I've tried the guides supplied in this forum, but still can't get passed the installation screen.
Thank you !

No, just install wizard "loading" . when its done it either freezes the computer , or does nothing.
I have tried to open it using "compatibility" which tells me to use win 7. But no luck.
Looking for a way to just push it too the phone. Seems easiest.

I can use 6.16.651.2 flashableRUU ?
The phone is unusable right now, bootloops. I thought I had to be s-off to flash anything but the firmware that's present. Am I wrong?
My end game was to use the phone on at&t. I thought I could flash a gsm ROM to accomplish that.
Can I still s-off and sim unlock lollipop? Or at least s-off and downgrade?
Thanks for the help

I tried downloads from here:
[RUU][Firmware]Sprint HTC One | 6.16.651.2 | *Updated 2.10.15*
And I also tried the RUU from the official HTC website.
And I also tried the ripped "firmware only" from http://forum.xda-developers.com/showthread.php?t=2503646

There is an ruu in that thread that has a fastboot flashable zip. You might want to read through how to run it on your device. You shouldn't ever flash a gsm Rom to a Sprint phone. The mount points are different.

Solution: get a new computer.
Not sure what was going on but I could not get the ruu to run on windows 8.1. Drivers, adb,fastboot all working on the computer. I couldn't find the problem.
Dug up an old windows XP machine I have , worked in an instant.
No knowledge gained.

The RUU exe take a lot of RAM to run. please make sure you have no other programs running when running the exe. If you device is stuck in a boot loop try power the device down and into recovery mode. Then connect to terminal when the RUU ask to connect to the device. My guess is the the RUU is corrupt and try re-downloading the file. If all else fails relock the boot loader and try returning to stock.
