RESOLVED-[Q] HTC One M8 (HK)- Help flashing Lollipop

Hello all, I have searched for more than a couple hours and just seem to be getting nowhere. Here's the deal: I have an HTC One M8 with TWRP, root, an unlocked bootloader and S-ON. I want to install Lollipop, but can't take the OTA.
I know a little bit about what I'm doing, I tried to flash a rooted stock ROM but it didn't take. I wiped all directories but the internal storage. Also wiped the Dalvik, `but I could not get the update to take. I tried a few other things but out of fear of bricking my phone I wasn't very adventurous. I flashed the backup I made beforehand and it worked fine.
I think I have the wrong file...? Could my S-ON be the problem?
Sprint HTC One M8 (HK edition)
Android: v4.4.4
Sense: v6.0
Kernel: 3.4.0
Baseband: v1.08.20.0916
Build:3.31.654.2
All I want to do is flash lollipop. Will I have to lock the bootloader and go back to stock recovery to do it? Can I use adb sideload to install it via adb?
Thank you for your time.

I'm pretty sure my phone is toast.
PLEASE HELP, it worked just fine before I took your advice...
I relocked the bootloader and verified it multiple times before doing this. I made sure everything was exactly the way it was explained in the instructions, all files were correct.
I put the phone into fastboot, which I verified with adb.
I ran the Sprint_HTC_One_M8_HK_4.20.654.10_RUU .exe file and followed the instructions.
Both the program and pphone are currently frozen. They have been this way for almost 2 hours now.
The phone is stuck at the black HTC splash screen and the installer says
Updating...(0/7)... #(<--- these dots are still in motion like its installing)
Updating the ROM image on your Android phone...
[color=redPlease do not remove the USB connection from the Android phone or launch any programs during the update process.[/red]
Remember, this operation will take about 10 minutes.

I haven't done anything, its still plugged in.
I don't know what to do, can I just unplug it and flash my bavkup with TWRP?
PLEASE HELP I'M FREAKING OUT.

Ok, the phone is not recognized by adb but is still recognized by fastboot, can I reboot it into TWRP by using
Code:
fastboot reboot recovery
then just flash the backup I made before all this crap started?
*EDIT* RESOLVED
Never mind, I resolved it myself. I just typed
Code:
fastboot reboot
and hit enter. It booted right up.

I looked through it and all user made folders are gone, but all user downloaded apps are still there. I also noticed that superSU root access was off, but the 'apply on boot' option was turned on, could this be what crashed the updater?

Zenfone 2 failed update, can't flash stock firmware

I accidentally allowed the 2.20.40.183 OTA update, which rendered my phone useless. I tried putting MOFD_UPDATE of 2.20.40.174 on my SD card, but that didn't work.
Here's a few other things I tried:
Recovery menu: Updating phone, then dead droid. No menu appears.
adb sideload: adb didn't recognize my phone.
fastboot flash: Permission denied, or something along those lines. The write fails. Tried to flash system.img but it never did and nothing happened.
adb sideload through temporary CWM: Unauthorized device. Couldn't sideload.
Flashing through temporary CWM and temporary TWRP: Fails early on with Status 7. 2.20.40.174 is older, and this is apparently reason enough to deny me.
Does anyone have an idea about what I can do to fix this? Could I flash Cyanogenmod, then flash stock over that, using temporary CWM/TWRP?
My bootloader is not unlocked.

I'm not going to lie, that guide's a bit hard to read. I'll try to follow as best as I can and reply if this works for me.
I'd still appreciate any other advice others have.

All necessary to read.
Hope you fix the problem.

Fixed
I managed to fix my phone, but not with the method Mr Gourav so kindly posted. I chose not to use mr_gourav2000's IntelSoC fix because the guide was written in a way that made it very hard to follow, and I was unsure if MOOREFIELD was supposed to flash briefly or stay on the Device Manager. Regardless, I wasn't going to risk bricking my phone beyond help by pushing on without knowing what i was doing.
The key was bypassing Status 7 (or 1), which prevents you from downgrading firmware. If your phone says something like "Installation failed with Status 1" or "Status 7," or you get the "Can't install this package over newer build" error when you attempt to flash a previous firmware, this fix can help you. Funny enough, the fix was posted by the very same person earlier this year:
http://forum.xda-developers.com/showpost.php?p=65995574&postcount=116
First, download the latest full firmware from Asus' support site: https://www.asus.com/Phone/ZenFone_2_ZE551ML/HelpDesk_Download/
Then, open or extract the .zip file, and go to into UL-Z00A-WW-(Firmware.Version.Number)-user.zip\META-INF\com\google\android\ . Select updater-script (no file extension), and open it in a plain text editor like Notepad++.
Remove lines 1-6, beginning with "(!less_than_int" and ending with "getprop("ro.product.device") + "\".");". The result should look like this.
Then, insert the edited updater-script into the .zip file, overwriting the old updater-script. At this point, I should mention that one of the removed lines probably checked your phone's model number to see if it was compatible with the firmware. I sure hope you downloaded the right file for your phone. If not, brick city here you come.
Finally, put the edited .zip into a microSD card, and insert that into your phone. If you want to use the stock recovery to install the firmware, rename the .zip to MOFD-UPDATE.zip and put it in the root of the SD, then restart the phone and let it update. Presumably. I didn't use the stock recovery. I used the temporary ClockworkMod recovery to fix my phone, so I'm not sure if it's that simple. If you're using that temporary CWM, just go to the zip installation menu and apply the zip from external_sd.
If you were going through the same problems I was, your phone should boot into stock, unrooted firmware again. Pat yourself on the back and never do whatever dumb thing you did to get to this point in the first place (like absentmindedly apply an OTA update in the middle of a lecture)!
Once again, thanks to mr_gourav2000 for posting this fix earlier. I may not have understood the IntelSoC fix, but I did understand this one!

If it's the 1st boot it generally will as it is recreating cache, dalvik-cache or ART...
It seems to take forever to clear cache too when using recovery but about a heartbeat when using fastboot.... Just another quirk of the phone...

Thank you much
I gotta say, this got me on the right path. Though my issue was exactly the same the fix was a little different.
I had to use the next patch and that worked. Recovery is working now and I have to manually update, but still have root, so no real big deal.
Thanks again.

You need to flash boot, droidboot and recovery for the build you are using.
I use fastboot to do this but make sure developer settings are enabled and USB debugging is ticked before trying to flash.
To find the img files for the above mentioned, go to Shakalaka's pre-rooted rom thread in Android Developement, you don't need to download the rom if you don't want to but it sure makes rooting easy.
Find the version of Android you need and download boot,droidboot and recovery img files. Flash with fastboot using these commands -
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash fastboot droidboot.img
***Make sure the right commands are used or it may result in a brick...***

Phone no longer bricked (yay!), but not fastboot

The backstory: I have no experience with rooting and or flashing custom ROMs. Prior to today my ze551ml was completely stock, running on the official android M update. I had a need to do a factory reset, but the phone would simply reboot. I assumed this was a problem with the update so I download and attempted to install the downgrade to l. Naturally it crashed mid downgrade and I thought it to be bricked. So, I started Googling and realized I was able to get into fastboot mode, but not recovery. Following a guide I located I attempted to flash the preroot ROM located at the link below:
http://forum.xda-developers.com/zenfone2/development/rom-pre-root-img-t3079590
Well, it appeared to have worked, but now the phone refused to boot at all after being turned off. So, more Googling and I proceeded to follow the full unbricking guide below:
http://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
Partway through step 1.3 the phone restarted itself and booted right up into Android L! Success I thought to myself, but it was not to be. I proceeded to download the FOTA L update and it downloaded fine, but when I clicked to install it simply rebooted the phone. Tried a couple of other times with the same result. I realized that Supersu was installed so I did the full unroot assuming that was the problem, but to no avail. It appears that the updates can't install because the phone is incapable of entering fastboot or recover mode. Anytime I attempt to enter fastboot via hard key or through adb the phone hangs on the ASUS logo. Adb detects the phone when it's connected via USB, but of course fastboot can't because I can't get it into fastboot mode at all.
Any tips on how to get fastboot operational again so I can start applying updates again? Every guide I've located has started with "boot into fastboot/recovery" which simply isn't an option. Any help is appreciated.
Edit: Well, I think I've reached the end of the internet trying to google for a solution. The phone works, but it looks like it's stuck on build 2.13.40.13 until the end of its life. If anybody has any ideas I'm still hoping for a solution, but I can't find anything describing how to restore fastboot if the OS is intact.

Thanks for the response. I've tried this a dozen times, but unfortunately (this is going to sound weird) since it's not completely bricked it is only detected as Moorefield for a few seconds when started. This allows the xfstk tool to detect it and begin the download, but not long enough to complete the process so it times out. The only development access I have to the phone now is via adb, but since I don't have root I'm very limited in what I can do via command line. Since I can't access fastboot I can't achieve root. It's just a comedy of errors now.

The problem is that it's only recognized as Moorefield for a few seconds which isn't enough time for xFSTK to complete the install. Do you know of a way to force the device to stay connected as Moorefield?

Plug the phone to the PC, be sure the phone is completely off and then hold power + vol- for a few seconds. You must see the "Moorefield" driver permanent in the device manager.
Btw... I got the same problem (four lines, not bootloader, not OS; xFSTK FW+OS failed) and I'm stuck in this step :/

I've tried this many times, but it only shows Moorefield for a few seconds. I'm assuming this is because it has a fully operational OS so it doesn't stay in the generic USB device mode.
EDIT: I misread your original post. Holding power and volume DOWN does keep connect it in Moorefield. Thanks so much for that. The problem now is that once xFSTK gets to downloading the OS it reboots the phone which takes it out of USB mode and disconnects the tool. I'm still stuck where I was before, but that's a little progress. Any other thoughts?

New update. I'm able to get to the point of loading the OS from xFSTK by skipping the FW part, however it continuously fails. My assumption is because it can't overwrite the existing OS. Any other ideas?

Kidnova, reading this post I could fixed my problem. The "issue" was in the xFSTK where you put the flag (0x800000807). A guy on the threat said to put "0x80000807" instead of "0x800000807" (note that there is "0" from difference).
"those who are not able to keep device connected. take care of few steps
1. in xFSTK option menu change the flag override value to 0x80000807 not 0x800000807 ( don't forget to click gp value over ride)
2. while connecting to xFSTK attach usb to computer. hold power button for 20 seconds to make sure it power downs completely. then hold the power button down and click power button. wait till device vibrate or computer makes detection sound. leave power button but keep holding the volume button for few seconds"

Hi, got the same issues, I've read many posts. Tried all of the million options. What was your final way of doing it, do you remember?

My OnePlus 3 is a brick

Dear XDA Community,
in past 2 months i've been using CM13, constantly having some trouble with apps involving the camera, such as the camera app(surprise) and e.g. snapchat.
So yesterday I decided to update my CM Build, not knowing it would be to CM14 and with this Android 7.
So resulting from this I experienced a lot of issues with different apps, especially the google ones and for example Instagram. I DID NOT Upgrade my twrp, which was pretty stupid as I found out.
So this morning I checked again for CM Updates and Updated to Version Nightly...25 I think... but because I did not update my TWRP it did absolutely nothing except bricking my phone.
I already followed through the Guide for Hard Bricked OP3s (both steps) "http://forum.xda-developers.com/oneplus-3/how-to/guide-mega-unbrick-guide-hard-bricked-t3405700"
Though it sadly did not work for me. The Recovery tool and all works but when I want to boot my Phone the md5checksum pops up after the OP3 Logo and it tells me that everythings fine except "boot: failed".
I tried the procedure of the Hard Brick fix over and over again but nothing seems to work. I am fairly new to this whole Custom Rom stuff so I have absolutely no clue what do to.
Does anyone have any idea that could help?
Best Regards
Aliasalex

Try fastboot flashing the whole rom.

how? i dont have a factory img.
i tried flashing CM14 again and OxygenOs OTA. Currently i am getting Cache, Boot and System Failed.
In the meanwhile I managed to get twrp installed, but trying to install OS or CM via twrp didnt work either
//edit: ran the msm download tool again. Now only Boot is failing. tried flashing a boot.img via fastboot but didnt work
//edit2: when flashing the boot.img via fastboot my phone boots and works. When restarting without PC it still has cache and boot failure in md5checksum

try the 1st method you mentioned in the OP but flash https://www.androidfilehost.com/?fid=24591020540821926 . from what I understand, you need to full write all your partitions since they seems corrupted.

I'll help you when I'm home
Connect your phone to Fastboot. Go to device manager on Windows. Do you see something with OnePlus or kedacomm. I had this issue as well managed to solve it after 2 days.

You can't access Fastboot because of that Kedacom driver, if you right click it you should be able to change the driver.

Also I disabled Driver Signing Check when first trying to unbrick my phone.
I installed the drivers given in the Unbrick Test, it showed something like Qualcomm [something] 9003. There was something in between.

Nice, whdn you boot you still get those errors in red letter something with "failed boot". Then manually flash the boot. Img provided in the folder where you ran the Unbrick tool from. Command for Fastboot "fastboot devices", then "fastboot flash boot boot.img". Make sure that Kedacom is not in device manager when you are accessing Fastboot.

Help, might have killed my device

Not 100% sure of best place to post this, but I'm getting desperate now...
I'm pretty worried I've killed my device. After following the guide on how to root with Magisk, my phone is stuck on the white "loading" screen with a G logo. I've since tried to restart, but I can either go into fastboot mode or get the white screen when attempting to boot into android.
Tried to flash the latest factory image to fix it, but that couldn't get that to work. Now the phone isn't showing up on adb devices either. panicking a little bit here.
Does anyone know what to do?

ADB won't work unless the phone is booted into Android or in stock recovery for a sideload.
Does your computer recognize the device when you are in Fastboot mode and type "fastboot devices"? Try flashing the factory image again but make sure you have the most up to date platform tools from Google. Old versions are a common cause of issues.
Did you flash TWRP recovery or just boot to it to root? If you still have stock recovery you can try a factory reset from there but any modified images you installed might be the issue.

like Fury said, your platform tools need to be updated, same thing happened to me.

What didn't work when you flashed the factory image? Do you have the latest sdk tools version of fastboot and adb?

Thanks so much, this is where I was going wrong. Have gone into recovery and rescued it.
Tried the process again to get Magisk working, but ended up the same although this time the white screen only went on for a while before I got an error saying my data was corrupted. Tbh, after all the stress I'm just going to give up on this and live with the phone in stock. All my drivers and adb were installed and setup today, so everything is up to date.
edit...
Not out of the woods yet. After restarting the phone and going through the setup, it's not detecting the SIM card or any wifi networks. I've installed the OTA and wiped data once more after having this problem, still not resolved.

It sounds like you are trying to install Magisk v17.1 like I tried. If so you need to use v17.3 beta. If you follow this thread you should be fine. It even tells you what to do for your original problem, just takes some reading and patience.

I tried it with both 17.1 and 17.3, so not sure what the issue is. Seem to have finally booted up properly with wifi and signal working, so hopefully it's all good now. Gonna give up on rooting.

Not 100% sure of best place to post this, but I'm getting desperate now...
I'm pretty worried I've killed my device. After following the guide on how to root with Magisk, my phone is stuck on the white "loading" screen with a G logo. I've since tried to restart, but I can either go into fastboot mode or get the white screen when attempting to boot into android.
Tried to flash the latest factory image to fix it, but that couldn't get that to work. Now the phone isn't showing up on adb devices either. panicking a little bit here.

you may want to try to totally uninstalling Magisk frist with the official latest Magisk uninstaller and reboot and then do a complete factory reset. this has helped me in the past.
my new pixel 3XL will be the first Android phone that I owned that will not be rooted.
