HTC M8 gives Encrypted message, Locked boot loader need some serious help....

[na-dev99]

Hi All,

Thanks for all your continuous efforts. I am in a pickle now. I was using this phone M8 and suddenly something happened.. first it complained about USB charging and then when I rebooted the phone it says the phone is encrypted.. and I never used a password ..no matter whatever i use as password, it says password wrong, reset your phone and when I reset, it gives me the same encryption message. I read on how to power and volume up down button, found that bootloader is locked and I was using the same stock rom, never installed custom recovery
See the attached screenshot and please suggest me if there is any hope of recovering this phone or not.

.

Thanks..

When I am doing adb devices
It only says " List of Devices Attached " .. but does not show any..

fastboot getvar all returns only < waiting for Device >

Thanks.

Here is another information, not sure how much help it will be:

When I boot the phone, it boots and shows a message:

Your Phone is encrypted
To decrypt your phone, enter your screen lock password.

There are two buttons, decrypt and emergency call
And it says 30 attempts remain before device data is deleted.

But I never used a password, it was just a pattern. No matter what ever i use as a password, it gives a message saying Password incorrect. You data will be wiped, and a Button comes
" reset phone".
I already clicked this reset phone almost 15 times, but it is not doing anything, it says resetting the phone but boots to the above screen showing Phone is Encrypted. And the 30 attempt message is still there.

Thanks

After reading may other thread, I installed the HTC Sync Manager along with drivers.
Installed Fastboot.

Then from boot loader went in to Fastboot.

Now typed "fastboot devices " on command prompt. This time got a result. So i went ahead and got the identifier tokens as per HTCDEV site. Finally got my unlock_code.bin file. Used this file to unlock the bootloader.

The strange thing is the phone came up saying resetting data "Yes" , "No" Option. I selected "Yes", then once it rebooted the same "Encryption Message screen came. I went to the boot loader, it still shows "*** LOCKED***. Did try to run the "fastboot flash unlocktoken Unlock_code.bin" command again and the same thing as above, it is the same result...same locked status..

I do not know what else I can do being a newbie...Please help.

I don't know much about your problem .. hopefully it is not some hardware problem like the emmc is corrupted.

Have you tried to run a RUU ? RUU will wipes everything on your device and replace it with new image.

If you're willing to try, here is the link for your RUU - http://www.htc.com/us/support/htc-one-m8/news/

Thanks your for the suggestion. I went ahead and downloaded the ROM from HTC website.
Could you please give me instructions how to update from fastboot. My Surface Pro 3 is windows 10. On the HTC Synch Manager it is not recognizing the Phone. But on fastboot from boot loader the command prompt shows me the device. So please show me light.

Thanks.

When you have fastboot working correctly that's good enough. You don't need HTC Sync Manager (please uninstall it .. later after RUUing completed you can reinstall it if you need it)

Make sure you installed the latest HTC Sync Manager - http://www.htc.com/us/support/software/htc-sync-manager.aspx

Install it to have all the necessary drivers and files needed for RUU to run, uninstall only HTC Sync Manager but leave all other things (don't uninstall them).

Put your device on bootloader/fastboot mode then connect to PC.
Right click the RUU exe and select run as administrator and follow all the instruction - agree, next, next, update, blablabla until it completed.

ckpv5,

I did as you said. I went to boot loader/fastboot. Ran the RUUXXX.exe as admin. It first rebooted the phone and expected it to go to bootloader, but it did not , and finally said usb connection error. Do I have to manually put it in to boot loader each time the phone restarts ? -Thanks

 

[na-dev99]

ckpv5, I did extactly as you said. Put the phone on bootloader/fastboot. Started the RUUXXX.exe as Admin. The utility did recognize the phone and rebooted it and the message said, waiting for bootloader. But the phone started the boot to the HTC white screen. The uility said USB is not connected and USB error. Will I be able to manually put the phone to bootloader when it says waiting for boot loader....?

 

[ckpv5]

Forgot to mention that you need USB 2.0 and not sure whether your Surface Pro has that. If no, you need to find another PC with USB2.0

It is really late over here (2.40 am).
If you can find a RUU zip for the same version, you can try to install it with external_sd method or fastboot flash it (this should work with USB3.0).
If you can't find one .. I'll tell you how to get one tomorrow as I'm already in bed

I used my surface pro 3 docking station , and changed from usb 3.0 to 2.0 port. But the result is same. waiting for bootloader and then the phone started the boot to the HTC white screen. The utility said USB is not connected and USB error. I tried Fastboot reload-bootloader, it starts booting to the HTC white screen and to the encryption message.

Basically I am seeing that the software is Official, Locked and S-ON. Hboot is 3.19, OS is 6.12.1540.4, Cidnum - BS_US001, product - m8_ul_ca

Let me know if there is any hope for this m8 or not.

As I mentioned before, I don't know much about this encryption problem. The only suggestion that I have is to run RUU to replace all the image with stock one but you seems have USB connection problem which usually related to USB3.0

(It will be different approach if you have a TWRP installed where you can simply format (not wipe) data partition to fix it) - running a RUU will format your data partition too (hopefully)

Since you can't try on other PC, do you have a microSD ? If yes, you can try these :

1. Right click your PC start menu and select "run" and type %temp%
2. delete all possible files from this temp folder (some of them you won't be able to delete)
3. Right click the RUU exe and select run as administrator - let it open the agreement and you accept it .. no need to click next or whatever
4. Right click your start menu again and select "run" and type %temp%
5. You'll see two new folders are created - copy out ROM.zip and htc_fastboot.exe from one of those newly created folder (to your desktop)
6. Rename the ROM.zip to 0P6BIMG.zip
7. Put the 0P6BIMG.zip on your microSD root (not in any folder)
8. Put the microSD in your M8
9. When you're at fastboot/bootloader, press power once to go to hboot screen.
10. hboot will scan the 0P6BIMG.img and ask whether you want to update
11. volume up to update and let it run until it say to reboot.

the htc_fastboot.exe is for you to keep for the next method if the above fails.

I tried in another PC as well with USB 2.0 , but when RUU waits for the phone to comeback to bootloader, the phone directly goes to the boot loop. the USB works but only when the phone is in fastboot mode, it is being recognized.
I am ok with data being wiped, i have my contacts , mails, chats etc. are backed up to another phone which I am using now.

I have an SD card , I am going to try your tip as well.
Thanks for this tip, I will do this in evening today. I am in CST, so came out to work.

 

[na-dev99]

I followed your instructions and used the 0P6BIMG.zip to an sd card. Under HBOOT it started parsing the file. And after I did the volume up to move on with update, it restarted and from there went to boot loop and showed me the data encryption message. Same behavior as running RUUxxx.exe .

Is there anyway without reboot will I be able to wipe clean from firstboot ?

Thanks.

I checked the thread, But the solution has a condition that , BootLoader should be unlocked and the phone should have a custom recovery like TWRP.

Mine is a different case, bootloader locked, S-ON, no custom recovery. Basically the phone is never rooted. Even unlocking the bootloader also takes me to the encryption message and it;s not responding to the unlock token received from htcdev.
