This is process that worked for getting 5.1 to install correctly.

1. Unlock your bootloader (several threads have guides for doing this through Sony's developer portal). The process is not difficult as long as you have adb/fastboot drivers installed and working. This step will WIPE your phone.

2. You need to reboot to the bootloader and then flash the proper 5.0 FOTAKernel.img partition file. Steps and link to the proper file are back in the middle of this thread.

3. Reboot your phone and let it fully load up. Go to Settings -> About Phone -> System Updates and check for update.

4. Let the OTA update download and then it should install correctly.

On a side note, the 5.1 OTA update ran fine after doing this, however, it again failed to update the FOTAKernel partition, so I they flashed the 5.1 FOTAKernel.img to make sure recovery was up to date for any future OTA.
[Sony Xperia Z Ultra] sajazzman007:
The Moment of Truth. Just reloaded it lets see what we got :) Thanks gentlemen for all your help ;) I followed the direction and i still unable to update. i unlocked the bootloader, flashed the new 5.0 FOTA.img partition and still nothing. is there a different way to flash the Kernel? I'm new to all this but awesome at following step by step barney style directions.
[Sony Xperia Z Ultra] sajazzman007:
I have been working on this the last 4 days and I don't think I am making any progress. I have seen more post on this phone than anything. I downloaded the three files and tried to use flashtool to install them and i receive a fail notice on all the files. Can someone please tell me where am I going wrong with this or post better directions or installing these files? Does the phone need to be rooted in order to install the files? I was able to unlock the bootloader and I have been stuck since. I have downloaded flashtool, the three files from doomlord, what's next? Which files do I install first? Can you use flashtool to install these files?
[Sony Xperia Z Ultra] Rommul:
Is there a reason (besides rooting an unlocking) why some people have no problem but some are being dragged through hell?
[Sony Xperia Z Ultra] egzthunder1:
What version of Android are you on right now?

If you are on 5.0, all you need to do is download the 5.0 fotakernel from doomlord's thread (which you did according to your post). Once you are done, putbyour phone in fastboot mode, open up adb (which I am assuming you have installed on your PC. If you don't, look for something called "minimal adb and fastboot") and type the following (mind the case as the syntax is case sensitive)

fastboot flash FOTAKernel name.img

Replace "name" by the name of your file, which you need to place inside the folder that contains fastboot and adb. If you installed the program i mentioned before (minimal adb and fastboot), you will need to place the 5.0 fotakernel in its folder (c:\program files\minimal adb and fastboot .... This is my path anyways, yours may be different).

You should now get an Okay instead of a failed. Boot back into system and try to upgrade again. It should work this time around.

Hope this helps.

I got my notification in the middle of the day. I waited until I got home to do it (so it wasn't exactly right away) but I only tried once and it worked.

It updated from 5.0 to 5.1 right away. No root no unlock. Nothing.

This just seems strange to me. At any rate I don't want to distract the thread.
[Sony Xperia Z Ultra] sajazzman007:
I have android 4.4.4 installed. I have the fastboot and adb installed. Is flash tool not the program I should be using to install this?
[Sony Xperia Z Ultra] egzthunder1:
Can you get the 5.0 OTA update to flash?
[Sony Xperia Z Ultra] sajazzman007:
No I cannot get the 5.0 to flash. It comes up as an update and when I try to download it it starts to download and then an error comes up with the android on his back and a red triangle over him. I has been in 4.4.4 Kitkat. I am just stuck. What I was thinking is do I have to flash something to get to 5.0 and then use doomlords file to get it to 5.1?
[Sony Xperia Z Ultra] sajazzman007:
Now something is seriously wrong. My phone won't even boot up it goes from the google start up screen to the android laying down with a red triangle that says no command. Please help.
[Sony Xperia Z Ultra] egzthunder1:
You are in stock recovery. Your device will not restart into system unless you get it to do it by hand. You can either turn it off completely and reboot in fastboot mode, and then simply press on "Start". Or when you are in recovery, start pressing combinations of power and volume down buttons (simultaneously or one at a time while leaving the other pressed). This will reveal the hidden recovery menu and from there you can just reboot into system.

I don't understand why you can't update to 5.0 but try to roll back to 4.4.2 and go from there.

I tired both and it it is still not starting. Using both methods it goes back to the same screen. Are their any other tools that I can use to boot my phone up? I think if I can get it running again I am just going to leave it alone. It's not evening showing up in my computer.
[Sony Xperia Z Ultra] egzthunder1:
Fastboot isn't showing up? With the device completely off (press and hold all 3 buttons for 5 seconds... It will vibrate 3 times), plug it into your computer holding up the vol up button. You should get a blue led.

[Sony Xperia Z Ultra] sajazzman007:
Fastboot is showing up however if I place it in recovery mode it does the same thing, it will say no command and the Android with the red triangle error. Nothing on it will load. I tried to use the tool hoping that I could load any of the 5.0 files on it, and nothing. The phone has an unlock bootloader and is not rooted. I can say if I knew this was going to do this with the phone I would have stuck with Kit Kat. Is it possible to contact you via the phone and you can possible help me troubleshoot this issue? I was a Samsung guy and used to load roms etc. with no problems however, this is a headache.
[Sony Xperia Z Ultra] sajazzman007:
ok I can get into Team Win Recovery Project. From here how do I restore the phone. There are several options such as install, backup, mount, advance, wipe, restore, settimgs, and reboot. Reboot takes me back to the initial problem. It will reboot and no command error. On the main screen TWRP screen what do I do next?

Jon
[Sony Xperia Z Ultra] egzthunder1:
First of, do a back up (just to be safe). I do hope you have a good backup of all that is in your phone because you might have to do a hard reset.

The no command error as I said, is the initial screen of stock recovery. One thing I noticed on your previous post is that when you are in fastboot and you put "recovery", it takes you to that screen again. You need to press on " Start" to boot into system. Have you done this?

It contains all the OTAs. Here is what you are going to try to do. You need to get back to stock recovery and get it to sideload mode (Apply update from ADB). I have just sideloaded every single package from the aforementioned thread in an old ZU that I have with a broken screen and it worked like a charm. I flashed back from all the way from 4.4.2, but since you are on 4.4.4, I would simply download that and sideload it. I was getting the same error in my device, saying that it was finding something in my system that shouldn't be there. Once I sideloaded a fresh image, I was able to update without a hiccup.

I did have to update the FOTAKernel to 5.0 (the one in DoomLord's thread) otherwise the 5.0 update would not flash.

Hope this helps you.
[Sony Xperia Z Ultra] sajazzman007:
Yes I have done this and it goes back to the same no command screen. You mention stock recovery what is that? Is that the recovery with the blue led? You Also mentioned side loading? What is that and how do I do it using ADB? I apologize for going off on a tangent however I thought for a second I did serious damage to my phone.

Go to doom's thread and download the full 4.4.2 update if don't already have it.

Now grab these files here:

Now grab Version 1 of doomlord's kernel and flash that via fastboot.

http://xdaforums.com/showthread.php?t=2579005

Now boot your phone, when the google logo pops up the phone will vibrate immediate hit the up vol rocker to go into CWM recovery. Go to install zip, make sure signature verification is turned off, then from the same menu install zip from adb (or sideload from adb or something similar, i don't remember). In device manager on your windows machine you may see some device with a bang, update the driver, use the have disk method, and point it to the sony drivers you downloaded, specifically the sg0109adb.inf file. Now adb should see device. Now flash the KOT49H_nochecks zip that has the first two lines on the update script removed using "adb sideload <filename>. I may have packaged that file badly or used a bad cable but when I flashed it the phone wasn't stable even after several wipes, so you should just then follow doomlord's guide to go back to 100% stock:

http://xdaforums.com/showthread.php?t=2761698

since it will now work. Do this part if you are having stability problems with the phone. I was able to update from 4.4.2 all the way to 5.1 without any issues.

I am looking to download the stock recovery for version 4.20.651.10.

I've found the zip of all previous recoveries here: http://xdaforums.com/showpost.php?p=56557802&postcount=84

Is there a place I can download the stock recovery for 4.20.651.10. I need that recovery so I can download the update just released, 4.25.651.14 as I run stock with root and my current recovery is TWRP. The older recoveries are not allowing the update to run.
[Sprint HTC One (M8)] ReproOne:
I extracted the recovery from 4.25.651.14 and flashed it. The update applied, but upon final restart it locked up and currently it will not start. I can force it to reboot, I get the startup screen for a few seconds, then it goes to a blank screen.

Any ideas?
[Sprint HTC One (M8)] dopy25:
Either flash a custom recovery again from fastboot or RUU. Are you still unlocked bootloader? If not and you modified any system files, that would be why it will not boot.

Unlock your bootloader and it might boot with stock recovery. Otherwise RUU is the way to go, then you can take the OTA, unlock the boot, install custom recovery and root and do whatever you want from there.

Also, stock recovery is not required for RUU but you must lock the bootloader if you are s-on, not sure about s-off but if youi are and try, if it fails just lock it and try again.
[Sprint HTC One (M8)] ReproOne:
It will not boot to fastboot, just the splash screen then blank. Is there a way around this?
[Sprint HTC One (M8)] dopy25:
Have you tried to boot into the bootloader and then using the volume keys to navigate to "fastboot" and pressing power?

S-ON or S-OFF? If you are S-ON you should have the super security still and would have almost no possibility of a brick and should still be able to boot into the bootloader, if you can at least get there you are still in a (semi) working device and only takes a few things to do to get back to fully functional.
[Sprint HTC One (M8)] ReproOne:
I am s-on, it is only HTC unlocked so I can have root access. So far, I cannot get it to boot to the boot loader via power and volume down.
[Sprint HTC One (M8)] dopy25:
That's odd, all you did was unlock using HTC dev?

Are you charged to enough battery power? That could be a huge factor.

Yes unlock with HTCDev and then root. Phone charge 91%.
