Updating and restoring to stock issues

I have an HTC One by T-Mobile, Our update was released Monday. I tried to update but when it rebooted it went to install and failed to install, I looked up some information that say usually the cause of the failed install for software system updates is because of an unlocked bootloader and custom recovery. So I've tried to restore to factory OEM settings but every time it fails to up restore to the factory update as well. I'm at a loss here and no Idea what to do. I can flash any custom roms I want and those seem to work and flash just fine but If I try anything else like reverting to OEM stock it doesn't work. Anyone have any Ideas?
Before anyone asks, I've tried doing a RRU restore from desktop and .Zip on my phone and neither work. Both fail.

Get s-off and restore any RUU.. After restore, better get s-off before you update, you won't be able to get it after the update.

you need to flash the stock recovery and lock your bootloader to be able to do the update.

I'm pretty sure you don't need to relock the bootloader for OTAs, you do however need 100% stock ROM and (a very close) stock recovery for that ROM.

Only for OTAs, to run a full RUU exe, I do think the bootloader has to be locked/relocked

Not going to matter anyway, I accidently wiped my whole OS. I've tried using adb Sideload but it wont detect my device.

Restart your computer, also update to latest HTC drivers and adb sdk.
Alternate method, use an OTG cable with a USB stick with a ROM.ZIP on it, and mount "external sdcard" (or whatever it's called) in custom recovery.

I can boot into fastboot on my phone but I've no idea what to do from there.
Edit: HELLS YEAH! I got it! lol had to relock bootloader using fastboot and then go back into fastboot on my phone and run the RUU.exe and it worked this time! SOOO freaking stoked and happy! I've been up for 7 hours straight trying to fix this!

Nice. Please update the thread and put SOLVED

[Q] Trying to downgrade

Firstly, thanks to SafinWasi and Red_81 who both helped me on other threads, this question follows on from those threads.
I'm trying to downgrade from 7.4.9 user 4952320. Eventually, I will probably install CM11 (I tried once and bricked my device), but for now I just want to downgrade the OS and be able to change the wallpaper, I'm sick of the black paper. (I've tried Stunts wallpaper fix and it didn't work)
When the device upgraded to 7.4.9 I made backups of the whole 12 img files (inc boot0block).
I've read that you need a 7.2.3 boot image to be able to install TWRP as part of the CM11. I obtained a rooted 7.2.3 boot image from Red_81s google drive. I then flashed that boot image and tried rebooting the device. No joy. I got the red triangle. I flashed my 7.4.9 boot image and rebooted. The device rebooted and worked as normal.
I then flashed the 7.2.3 rooted system image and rebooted. Again I got the red triangle. I then flashed the 7.2.3 boot image, (so the device had 7.2.3 system and boot images) but again I got the red triangle.
So, how do you downgrade? Should I have flashed all 3 of the 7.2.3 images? (I don't have the checksums of the images so I recognise if one of the images was corrupted the exercise was doomed to failure.)
By flashing my 7.4.9 system and boot images, my device was restored to functionality, and I learned a bit, but not enough to achieve the goal. I'm hoping someone can show me how to downgrade.

Thought I'd add that I did try Kindle Fire First Aide but got lots of errors about dropbox not being available.

Did you flash the system and recovery? Both are needed to successfully downgrade. I always wipe data too.

You need to flash a custom recovery on a second bootloader as well. You can't just flash the system. You also need to flash the 7.2.3 boot.img and stack override. Any tutorial dealing with this mod will include all the steps. It important to pay attention to details and not skip any steps. http://forum.xda-developers.com/showthread.php?t=2128848

I didn't flash recovery, at my first attempt, just boot, then I tried boot & system. Both tries gave the red triangle.
I've tried again, with all 3 rooted images from your gdrive - recovery, boot & system, and again got the red triangle. I tried again with the 3 images from another source (my own unrooted 7.2.3 backup when I first got the HD7) and again, got the red triangle.
I haven't wiped the data because I would prefer to keep it so I can use the device (and think it should be possible to downgrade without wiping). I haven't been able to find a command to wipe just the cache...
So I'm more than a bit puzzled. The fastboot commands (eg fastboot -i 0x1949 flash boot boot.img) all return with "sending" then "OKAY", then "writing", then "OKAY" so I don't think there's any problem there.
I must be doing something wrong or missing something.

Thanks for your response, but at this stage I don't want to flash a new custom ROM, that may (probably will) come later, but at this stage I want to just downgrade. I've been warned that installing TWRP etc may leave the stock system in a bootloop, so a working stock backup won't be possible.
As I have to downgrade the stock boot image anyway in order to install a custom ROM, I thought I'd downgrade the whole OS in order to have a functioning stock system, then I can make a backup of it in TWRP, then install a custom ROM.
If I'm having problems with a simple downgrade, I might have more severe problems flashing a new ROM and be left with a dead device like I was previously, hence my caution and not wanting to move on until I know I can recover to the previous step if things go wrong.

Did you try downloading the original 7.2.3 from the thread and try flashing them ?

Yes, I did. Tried them twice, in a different order (didn't think it would make a difference but you never know....). Anyway, tried again, this time, wiped data and cache (took 45 mins) and it worked! I now have 7.2.3 and access to Gplay (was already there).
I haven't registered it to my Amazon account yet, so email and contacts don't work, and am wondering if I should go straight to installing a custom ROM. I'm thinking if it isn't registered to Amazon, then they can't update it via OTA...... or can they?
It's been a bit of a task getting this far, but at least I'm more confident about getting into ADB and Fastboot!

well, I know the answer, yes, even though it hasn't logged into an Amazon account (I realise they pre-register them to your account before dispatch), it updated back to 7.4.9 just as I finished the above post and whilst I was thinking I should disable OTA updates using KFFA!
flip. This is turning into hard work. lol, still I know how to do it now.

I was having many issues after the last OTA and got mine to cm-11-20140609-SNAPSHOT-M7 last night. Mine was at 7.4.9 also. I followed rootjunky youtube videos to get mine re-rooted, flashed and working. After getting it rooted, he uses Fire Flash app to put twrp on the Kindle. I deviated a little and put the twrp 2.7.0.0 version other than that, I followed to a T. Once I got all that done, I went on the internet to Hashcode's repository and downloaded the newest cm-11 UNOFFICIAL he had listed directly to the device. I downloaded the latest Gapps from cyanogenmod and then booted into recovery(twrp) and installed. Everything is working beautifully now. Everything seems faster and smoother so far. I did go ahead and do an update from the about area in the settings to cm-11-20140609-SNAPSHOT-M7. I was also able to get all my books that I had purchased through kindle in the kindle reader.

Nice to know. Think I'll be doing something very similar, now I've made backups of 7.4.9 "just in case". Just have to go through all the above again!

[Q] Chronic phone problems. Want to nuke the whole thing and start again.

I have had inklings that something was a little off with my installation for a little bit. It has always been like pulling teeth to get a rom installed on my htc one, and for the most part I had to sideload everything I wanted to install.
I ran a snapshot of cyanogen for a while, but my phone refused to update to new versions. I got frustrated and installed the nocturnal GPE rom which worked fine for a few months, but recently would not connect to the networks. I attempted to run the factory reset command from TWRP, but the phone hung for an hour trying to erase the cache. Then when I restarted the phone, instead of seeing the boot screen for the GPE rom I had most recently installed, I saw the cyanogen boot screen.
I have had little luck reinstalling roms since then and also have some problems with the recoveries. I have to install CWM or whatever recovery I dont have installed to even get sideloading to work. I've installed the nocturnal GPE rom again, but when it gets to the screen to select English it just restarts without warning.
Right now I just want to know if it is possible to nuke everything but the bootloader and just start fresh from factory settings. I want the nightmare to be over!

Could you screenshot the bootloader for me?

Maybe you've got a whacked recovery. Reflash from fastboot from an md5 verified .img (make sure its m7wls version of TWRP). You should have no problems wiping any partition from within.

[Q] Another I completely screwed my phone thread

I have been trying to flash a custom ROM and achieve S Off for a couple of days now and through lots of searching and trial and error made good progress on a system much more complicated than my previous phones/tablets that I have rooted. I was feeling good yesterday and had figured out the whole HTC DEV thing, how to use Fastboot and ADB. Unlocked, flashed recovery, used rumrunner(said I needed to swap ROMs first), and then tried to use the CM installer. This is where things went sideways. The installer found my phone and said everything was cool, then said complete. At this point my was stuck on the Android with its front cover open screen. After waiting a while, I was forced to reboot. Now I am stuck in a bootloop. I have access to Fastboot and Recovery (TWRP 2.8.1.0) but can't mount anything and sideload refuses to work. I have tried 4 different roms with that. I failed to make a backup in recovery once I got it installed but I am not sure that would do a damn at the moment anyway. I have seen a number of threads with similar problems but can't get anything suggested in them to work in my case. Thanks in advance.

I'll suggest you read the OP before flashing anything to your phone, especially when you'll have s-off. ARHD GPE (google version) require S-OFF to be used (and clearly mentioned in the OP of ARHD GPE) If you keep flashing things without reading when you'll have s-off, you'll probably end with an hard-bricked device
From arhd GPE OP:
Android Revolution HD 6.1
Google Edition
You need S-OFF, otherwise you'll experience boot-loop!
You can't use ART with deodexed custom ROM
You need TRWP 2.6.3.3 custom recovery!

Try re download the zip (or try an other rom)maybe you just got an false download. i also had some trouble with my m7 back in the day.
But in your case now you are stuck with no os or bootloop, i give you as advice to follow an soft unbrick method it worked for me, or if you have an usb otg cable and usb or and usb otg thumbstick, put the rom on that usb and connect it to your phone and then try to flash it (if your using twrp you have an option to choose from wich storage you want to use)
Also a piece of advice, when flashing roms, kernels etc please have your phone charged above 50% (just in case).

Can you please post the output of
Code:
fastboot getvar all
please remove your imei and serial number.
Depending on which variant of the M7 you have you probably just need a different version of recovery to install a CM rom. I think they prefer TWRP 2.7.x.x. Post the getvar and we can see what you have. then I can give you a better informed instruction. :good:
P.s also check the md5 of the rom zip you downloaded. Use this tool www.winmd5.com the correct md5 should be listed with the link you downloaded the rom from

failed to mount /dev/block/blah blah blah = needs "block:by-name" support which twrp 2.6.3.3 doesn't have
everything explained here
So update your recovery
and do what danny said above so he can confirm you have the right rom/recovery for your device.

Your getvar looks fine this rom should work fine with your device. Download this version of TWRP https://www.androidfilehost.com/?fid=23501681358561860 (2.7.1.2). dropthe file in your fastboot folder and flash it with fastboot.
Code:
fastboot flash recovery "name-of-recovery".img
fastboot erase cache
fastboot reboot-bootloader
Once thats done reflash the rom with the new version of TWRP. It should flash just fine :good:

There are a number of ways to return to stock software. You can simply flash a stock rom through twrp or use a stock nandroid. look for rom that match your version main. 7.19.401.22
I think there is even an lollipop 7.19.401.22 RUU for your device but I'm not sure if it will work with s-on though because it's a zip but it certainly wouldnt hurt to try it though. You will need to relock your bootloader and flash it with fastboot.
I'll edit this post with links when I find them unless some one beats me to it

Sorry I am at work so availability is scetchy. I found the ruu but it's for the older 7.19.401.2 lollipop, this won't work for you because your s-on. Downgrading firmware is only possible with s-off.
You can use this stock rom though http://forum.xda-developers.com/htc-one/development/rom-100-pure-stock-5-0-2-7-19-401-2-t3044041 just flash it with twrp. The thread recommends TWRP 2.8.5.X no need to relock the bootloader or anything silly, just flash it like any other rom :good:
You'll notice that this rom is also for the older 7.19.401.2 so you will need to install the last OTA update to bring your rom in line with your firmware. Flash this recovery with the same method as twrp. (Stock recovery required for installing the OTA) http://sourceforge.net/projects/htcone/files/Recovery/STOCK/7.19.401.2_recovery.img/download reboot then just go to Settings>About>Check for updates.

Okay try this. Download the OTA but select the option "Install Later" connect your m7 to your pc and browse your storage. In the download folder on your phone you should find the OTA in zip format. Copy it to your pc.
Now open the OTA zip on your pc. Inside you'll find another zip called "firmware.zip" extract it then open it. Inside you'll find a recovery.img. extract the recovery file and flash it with fastboot. Now reboot to android and continue to install the OTA. :fingers-crossed:

Yes you will need to unlock the bootloader to flash the recovery, Dont forget to fastboot erase cache after flashing the recovery that is cruicial. You don't need to be relocked to install the OTA though.
When you select install now, the device should reboot to the Stock Recovery. At first the screen will just be black for a short while. Then you'll see an image of a phone with a Green ring and download arrow. If you hold Volume up and press the power button you will see the Stock Recovery and its progress in installing the OTA.
I'm not sure why your device was hanging on boot after installing the OTA. Maybe a bad recovery.img. that's why I say to get the recovery from the OTA file.

its still not working so i mite just install twrp and restore to cm12.1

When you select install now, the device should reboot to the Stock Recovery. At first the screen will just be black for a short while. Then you'll see an image of a phone with a Green ring and download arrow. If you hold Volume up and press the power button you will see the Stock Recovery and its progress in installing the OTA.
I'm not sure why your device was hanging on boot after installing the OTA. Maybe a bad recovery.img. that's why I say to get the recovery from the OTA file.

Sorry I am at work so availability is scetchy. I found the ruu but it's for the older 7.19.401.2 lollipop, this won't work for you because your s-on. Downgrading firmware is only possible with s-off.
You can use this stock rom though http://forum.xda-developers.com/htc-one/development/rom-100-pure-stock-5-0-2-7-19-401-2-t3044041 just flash it with twrp. The thread recommends TWRP 2.8.5.X no need to relock the bootloader or anything silly, just flash it like any other rom :good:
You'll notice that this rom is also for the older 7.19.401.2 so you will need to install the last OTA update to bring your rom in line with your firmware. Flash this recovery with the same method as twrp. (Stock recovery required for installing the OTA) http://sourceforge.net/projects/htcone/files/Recovery/STOCK/7.19.401.2_recovery.img/download reboot then just go to Settings>About>Check for updates.

Your still stuck with this? Try starting the process over, but do not relock your bootloader at any point.
Wipe system data and cache partitions with TWRP Advanced wipe
Flash the Rom with twrp as a clean install.
Reboot and download the OTA. Choose install later, then copy the OTA to your pc. Extract the Stock Recovery and flash it with fastboot. Reboot and install the OTA.
But do not relock your boot loader. Because when you unlock the bootloader, it wipes the device including the data/preload folder. If the preload folder is not intact the OTA will fail
