I have a Sprint HTC One M7, which recently got an OTA update. I tried to apply this update, but now I can’t boot my phone. It was previously on stock firmware, but unlocked and rooted, and its internal storage was encrypted with a PIN. Now when I try to boot, it shows the decryption password entry screen, but my PIN doesn’t work.
Here are the steps leading up to this situation:
Using Fastboot, flash the stock recovery. Previously, I had TWRP 2.7.0.1 installed, but I went back to stock recovery (from this thread) so that the OTA would work.
Apply the update. This causes the phone to reboot and go through the update procedure. I wasn’t paying attention to the progress bar, so I don’t know if it finished or not.
When I next look at the phone, it’s showing the exclamation mark symbol indicating that the phone has booted into the stock recovery. Instead of entering the recovery, I force-reboot the phone by holding down the power button.
The phone reboots. Now I see the decryption key entry screen, which appears to have been updated in the OTA—the visual style is different from before. I enter my 6-digit PIN, the same one I was using before the OTA to decrypt the phone.
I press the Decrypt button, but after a second the prompt text changes to “The password you entered is incorrect.” Strangely, the number of remaining attempts does not decrement, but remains at 30. I am unable to boot my phone.
I can still reboot the phone to the bootloader menu, and I can enter Fastboot or recovery. However, the recovery is still unable to mount the data partition.
For some reason, I can take screenshots from the decryption prompt screen using Power + Volume Down.
Please help me fix this! I would very much prefer not to lose all my encrypted data, if at all possible.

Many people when they first get a Nexus device, choose to unlock the bootloader right away to prevent a mandatory data wipe if they unlock it later. Myself and a few others have encountered a bootloop after doing so. If this happens to you, follow these steps.
1) If your phone is stuck in a bootloop, Hold volume up, volume down & the power button until the phone turns off.
2) Wait a minute as trying to turn the phone back on may be unresponsive.
3) Hold volume up, volume down & power to boot into the bootloader.
4) Toggle to recovery and press the power button.
5) When you see the android laying down: press and hold the power button and immediately press volume up. It should open the menu.
6) Choose wipe data/factory reset. When completed the phone will reboot and should boot to the welcome screen
Hope this helps anyone who has this issue!
If I boot once, then reboot to boot loader then unlock will I be ok? I'm getting mine tomorrow.
Thanks for the heads up. I have no doubt that I will run into this issue and these instructions will help.

Yes.
Suppose that's from the update that happens when you first boot, we all know how well OTAs and unlocked bootloaders get along.

This is related to the typical Nexus data partition situation: If the data partition is wiped, the partition needs to be regenerated in some fashion before it can be written to, and this can only be done by booting once into the OS. Recovery and bootloader are unable to complete this operation alone.
If you find yourself in the situation of having wiped both system and data, you must flash any bootable OS version to system & boot via fastboot, and boot into it once, before you will be able to install ROMs via recovery again.
This is very important and I do this with every Nexus device on first boot.

This help, also had to format "data" because i skipped the first boot and installed the recovery right away
Thanks for this post
I booted mine straight to bootloader when it came and unlocked it with no problems. I wonder why this only happens sometimes?
did those of you who got a bootloop have to download/install the OTA when it finally booted?
Phone won't factory reset.
I have an m8 with stock rom and recovery and not rooted or unlocked bootloader. It wouldnt turn on last night and now when i turn it on it requires a password to decrypt the phone. It has a little note in the corner that says "chameleon" which is the passcode. But when i enter the pass it says right password but decryption unsuccessful with a reset button below the text and when i click it and it boots into stock recovery but won't reset and when i manually erase userdata or "/data" it fails and reboots into rom with the password prompt to decrypt again. Pls help

Can you boot into bootloader? If so, flash the recent RUU that is compatible with your carrier (Requires MicroSD card) and rename the file 0P6BIMG.zip and press volume up if you want to start update (This will factory reset your device, so i'm warning you now.) After update, everything should be starting normally again.
Hi Guys,
After the disaster of updating to Nougat, I got a replacement from the store, I unlocked the bootloader and as part of that, the phone had a factory reset. After this, I put TWRP on the phone and reset again.
The first thing I noticed was that after selecting the wifi for the first setup a screen about resetting data and I did. Once the phone booted, I also noticed that the default theme was gone (gold) and no themes are actually being installed. I see the default icons from Android and not EMUI!
Now, to the main topic, I CANT GET TO FORCIBLY UPDATE MODE!!! Whenever I press VOL UP + VOL DOWN + POWER, the phone goes directly to TWRP, this means that I cant remount any firmware.
Any thoughts on why this is happening? Is there a way to install UPDATE.APP from the graphics without going to this mode?
Details below:

Android 6, EMUI 4.
Thanks for your help!
I tried to install twrp in my Moto e5 (XT1944-6) device. I flashed the latest twrp image using adb platform tools. But when I switched to recovery mode, the TWRP logo appeared for a long time.
Instead of TWRP UI, a screen came called "Mount". It told me to enter a password,and a keyboard was open. There were 2 options " cancel" and "change language".
But I wasn’t able to do anything. Touches were not working. After a few moments the screen slept.
When I clicked the power button, a complete WHITE SCREEN appeared.
I was trying to go to fastboot mode, but it was coming to recovery mode every time. After a few try, somehow I switched to fastboot mode & restart my device.
Again I went to recovery mode, but TWRP wasn’t there. It was the stock recovery and still it is. Please help!

stock overwrites the recovery, you must change the rom to avoid it, and the password thing is called encryption and to remove it you must hit cancel, wipe format data and write yes [THAT WILL ERASE ALL YOUR DATA]
Moin,
My phone was one day suddenly unable to boot into system nor Recovery, but could still enter fastboot.
Took me a while to figure out that USB Hubs let flash attempts fail too. (you can watch the drama in my older posts)
Now i was able to flash System back into a workable state and it looks like that recovery is also successful flashed.
BUT...i can enter recovery only ONCE per Vol - and Power on Button.
i have NO OTHER WAY to enter Recovery at all. i have no reboot option in system (LOS 18.1).
In fastboot/adb command and after one succsesfull reboot per keys, it always stuck after the Sony logo into a black screen. i then have to restart it into system with Vol+ and Power (one vibration) or shut down with vol+ and power for 6 seconds (three vibration) to get it either into fastboot (Vol+ and USB connect) or system again. then i have to flash it again to get into TWRP once. i tryed the latest twrp version (3.7.0) and one older version (3.3.1) that had once worked until the phone broke.
Any idea what is going wrong here. i have already try to completly wipe everything from the phone and try to fix SEL Linux in twrp. nothing seems to work. Did i miss something?
/€: Now it is again in the full broken state. recovery nor System won't boot anymore and end in a black screen.
/€²: Found the Problem: my lilca zip was polluted with altered files i forgot about.
