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?

[Q] Help! - Rooted Zenfone 2 (ZE551ML) bricked after OTA accidently

followed a tutorial (Cnncted's youtube clip - How to root the ASUS ZenFone 2 ) to root
Accidentally (very stupid) pressed the update option when an OTA update showed up yesterday (Jul 8 2015), and after that the phone won't start properly - stopped at in search of incredible...
No luck with trying to boot into recovery mode (power + volume up). It just vibrates once and the screen is black. Trying to flash recovery image with ADB and flashtool etc, but the MTP usb connection failed. If I connect it to the PC using the USB cable and then press the power button to turn it on (stuck in that ..."incredible" screen), device manager shows the Z200AD name with a yellow exclamation mark beside, and Asus ZenUI software will automatically start. But it's not really recognized by the PC.
So...if you have any suggestions for me to try, please let me know and that would be greatly appreciated!

p.s. This is a US version, so the it's the WW sku?

Same problem here. I have a rooted 551ML and on July 6th I received an OTA update. I installed it and I'm stuck in boot loop. I have hundreds of family pictures in the internal memory.
The good news is that I have access to boot loader and recovery.
I could not find any custom recovery for Zenfone 2. They are not out yet, right? Is there any way to copy the internal memory of the phone (that doesnt load the OS) to the SD card? Or to paste a file img.boot taken from a downloaded official rom and copy it over the corrupted one on the phone's memory?

If you can access the bootloader, you can do this:
http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
Btw, there is a custom recovery out there (TWRP, check the Development section), but you will need an unlocked bootloader to use it in your state (I think).
US version is the WW SKU btw. Hope this helps.

Joel, thanks a lot! I will give it a try.
fingers and toes crossed...

I faced this problem too. All I did was to flash the boot.img of my version using fastboot,
Then I flashed the firmware, without factory reset I started the phone.
I was continiously getting an error "com.android.process has stopped". Ignoring that, I just backed up my whole data. Did a factory reset. Updated
Boom!! Everything was normal... I hope this helps

Just a quick update - followed the method in the link that Joel referred to, and everything worked beautifully. I did get two error messages like “the contact stopped working..." “The process android.process.acore has stopped working.” I fixed this problem by clearing the data/cache from the "contact" app, and that did the trick without a factory reset etc.
I unrooted the device using SuperSU. The fastboot screen, however, still shows a random serial number 0123456789ABCDEF. Is there a way to revert it back to the real one? I do see the real one from settings - about - status.

Isn't everyone serial number the same? mine is.

This is something that I am not sure of. Yours has been rooted as well?
I would like to know what the fastboot screen looks like before rooting.

Pretty sure rooting didn't affect my fastboot screen at all.

actually i rooted my zenfone 2 and there was an OTA and i tried to install it without un-rooting my phone. the phone would not turn on and it gets stuck in the boot animation.
the phone wasn't detected by the ADB in my pc so i thought of installing some custom recovery, thought that could help.
i tried installing TWRP but i did not unlock the bootloader and now i am not able to enter in recovery mode either, everytime i try to get in the recovery modethe phone restarts and goes to fastboot mode.
please help.

I was having a similar issue where adb wouldn't recognize my phone but fastboot was detecting it. What I ended up doing was grabbing the latest stock firmware zip from asus, transferring it to my external sd card via adapter and renamed it to MOFD_SDUPDATE.zip. Then go into fastboot (restart with volume up key) and proceed to recovery. It should automatically update your system from there. The only bummer is having to re-configure everything.

Is it Brick or is there Hope ?

Hi Everyone,
I would gladly accept any help that is being offered. Thanks in Advance.
So I am not new to flashing my phones but Xiaomi has been one of the most frustrating experiences that I've ever had. So I flashed my phone with the Pixel Experience Rom but I wasn't getting 4G with it and I couldn't recall if I was getting 4G with the original MUI so i decided to flash MUI firmware .
So, Not really sure what I did wrong because i believe I could flash the firmware without any problems but guess not. So it flashed successfully and my phone rebooted into Fastboot and will not load into the phone. So booted into recovery and Red Wolf TWRP is asking for the encryption password which I normally enter and I do it again and behold it's telling me that the password is wrong which is am sure it isn't.
So I am unable to use Red Wolf TWRP to flash anything since i can't mount the storage section because of the encryption and tried flashing the phone with MiFlash but doesn't seem to work. It is telling me that the image and device is a mismatch which I don't believe since I've flashed those ROMS before.
So any helpful advice would be appreciated.

I guess you need to flash stock firmware in fastboot mode. Download fastboot rom from mi website. Power on your phone while pressing volume down keep pressing power button for some seconds to enter fastboot mode. Connect it with your pc and upon connection you will heard plugin sound from pc. Extract downloaded fastboot image and double click on flashall. Wait for process to complete. Your device will auto reboot upon completion

So just format storage, it will be no longer encrypted. Then mount storage in twrp, paste your rom of choice from pc and flash it. Unless im missing something here

A mismatch you say? hmm I have had this before and I managed to flash the rom without issues deleting some lines in a rom package. It's quite simple, just follow this little tutorial: http://en.miui.com/thread-178314-1-1.html

Thanks for the responses. I followed this guide here to resolve the issue.

TWRP for Sony XZ2c instead of Lineage Recovery?

Hi everyone
After some research, I can't find a succeful way to install TWRP recovery instead of Lineage stock recovery.
It's really embarasing because I'm currently setting up my brand new XZ2c compact to run the way I want it to on Lineage OS 17.1 with Magisk and Xposed modules, and I experienced 3 or 4 endless bootloop that led me to fully format my phone after bunch of hours setting it and tailoring it up... Huge waste of time, frustration overload, as you could expect. So, I really miss tremendous TWRP backup fonctionnality I used to run frequently on my old Z5c... :crying:
Does anyone here as figured out how to replace Lineage stock recovery on this device? Is so, I'd really to hear him out
Have a good week-end!

You don't install a recovery, but only temporally boot one

Thanks for your (minimalist) advice. Literally just lost 1 hour fixing the bootloop it just caused by following it, I'm delighted.
Behind my post, I was hoping to find someone who could explain a bit more the process of replacing/flashing/booting/(wateveryouwanti'mnotanexpert) a recovery, and at the same time avoiding me wasting more hours in bootlooping/formating/reinstalling. Hopefully, this time I succeed to came out of the bootloop without formating and reseting eveything, but I almost lost my nerves.
All of this is a bit cloudy for me, could you (or someone else that would give me a little of his time to) be pedagogue and explain clearly the whole proccess (and especially what you should avoid if you don't want to get stuck in a bootloop/getting scarying corrupted device message) ?

No one?

Wrong forum. Search in you device section.

Hi guys!
Today I tried again to install TWRP on my Sonyh Xperia XZ2C because LineageOS Recovery doesn't provide Nandroid backup, which is a shame.
I tried many ways described over the web, none of those worked, and I ended up with a boot loop at startup with that naughty message "your device is corrupted it cannot be trusted and will not boot". I can't boot to Lineage, neither to recovery. I'm stuck.
With device turned off, I can eventually press volume down, plug it to computer, access fastboot mode (blue led), flash+boot the LineageOSrecovery.img, then the device restart, Sony logo appears... and that's all, I'm stuck with logo in boot loop, and I can't go anywhere further.
I tried to change boot slot (without knowing if it could help with this problem at all) but I alway get "unknown option".
I'm panicking right now, I can't find any way out to this bootloop, if someone could help it will be sooo appreciated!
I tried hard to find a solution for 4 hours now, I'm completly stuck and I can't even sleep. That's why I finally reached out here.

In fastboot mode you should be able to flash stock rom

Is there any way to make the device boot on the Lineage partition without wiping everything?

For an unknown reason, I succed to boot on Lineage Recovery (not TWRP) this morning. I flashed LineageOs rom.zip using adb sideload. After rebooting, the recovery tolds me that I had to wipe everything because the system partition seems to be corrupted, so I did.
I'm a bit tired to lost everything since I made all of this to do Nandroid backups with TWRP........ but I have a fresh new install, my phone works again so it's fine.
But I still need to make Nandroid backups.
Kurtn, you seem to have skills and knowledge. As you can see, I didn't succeed to boot Twrp since october 2020. I don't see why it would be impossible with my device, I'm probably messing something somewhere.
Would you share your knowledge and help me booting/flashing TWRP without bricking everything again?

Could you make an answer instead of a single smiley?

Btw.
Code:
fastboot flash boot recovery.img
DOES install the recovery, since it's permanently flashed. Don't know why they (lineage) didn't change that.

However @tomboudiboudi , you could boot twrp manually using
Code:
fastboot boot twrp.img
With that, twrp should appear and ask for a password to decrypt your userdata partition.
If that works, you could try to flash boot this very same twrp.img. Maybe you need an additional twrp.zip too which will be sideloaded within twrp itself.
A note for you which might help: I wanted to update my lineage recovery manually using fastboot (older lineage recovery to newer one) and found that nothing (except fastboot) was booting at all after flashing this.
However, after dirty flashing lineageOS.zip, everything worked fine again.
Keep in mind that flashing a recovery will modify your boot.img. If this one doesn't work / is corrupt etc., your os won't boot up.

I fear you still haven't realized, what a/b means. The classic concept of having a recovery partition, where you can boot twrp at any time - doesn't apply.

You're right, there is no recovery partition.
As I said: Flashing a recovery.img will modify the boot.img.

Question Soft brick no backup

Hi all!
Long story short, I beefed it...
I tried flashing the unofficial twrp and accidentally did format all on spflashtool.
I'm two months in and for the life of me I can't fix my phone... I've even tried to learn how to write a custom OS myself to fix it but I'm definitely not smart enough.
So, here's where I'm at right now:
When I flash the engineering ROM, the phone boots normally and all that seems to work, but flashing the official MIUI causes a bootloop to the stock recovery.
In there, there's the message "NV data is corrupted".
I'm 2 months in now, so I've seen almost all google pages, so yes, I've tried flashing using the official tool, flashed vbmeta with --disable-verity and --disable-verification.
It's my phone and I have the box here, so I have both IMEI numbers which I managed to flash in the engineering ROM, but flashing the normal MIUI somehow deletes the IMEI numbers again.
I can get into fastboot so the bootloader is unlocked, but I can't boot into the system so I can't enable dev options.
please, if you can help I'm more than happy to answer any other questions and being called an idiot :')
help me, XDA, you're my only hope

Good evening, sorry for my bad English, but I have the same problem when this happened, I had miui V13.0.7.0 there, I got bootlop, I loaded V12.5.2.0 there and the phone worked everything except the network, try and let me know

You have to download the firmware and paste it into the platform tools folder and click flash all.bat
