Hi all
I have a BLU Life Mark phone running android 5.1. I can't find any specific tutorials for the handset, so have tried some applying the tutorials from other phones made by the same manufacturer.
I'm a complete noob, using a Mac, but managed to get the phone into fastboot using USB, terminal and adb, and run the oem unlock command.
At this point, the warning screen pops up, and I am given the option to press volume up to void my warranty and unlock the bootloader, or press volume down to abort.
Pressing volume up does nothing - the button is fully functional when the phone is operating! - but pressing volume down DOES abort.
I have enabled OEM unlock and USB debugging through the developer options, but occasionally when the phone reboots, OEM unlock is disabled again!
I would really welcome any suggestions - I can't find anything online!
Thanks in anticipation.

So, my Maxx suffered a power button failure and I should be receiving my warranty replacement from VZW sometime in the next day or two. Other than the power button not working, the phone is functioning fine. It reboots, runs normally, functions perfectly. I'm running .215 rooted and I want to return the phone back to stock before shipping it back. Problem is I can't access Boot Loader, no matter what I try. It's like it's not there anymore and when I command the phone into it using quick boot, adb, or the built-in menu, the phone just power cycles off. Let me try to explain:
I have Quick Boot installed and I can use it to boot into recovery without a problem. If I try to boot into Boot Loader, the phones powers off and stays off.
I've tried adb shell with the same results. I can connect to my PC and command the phone using shell commands but usin the 'adb reboot bootloader' command results in the same thing: phone power cycles off and stays off.
Even though my power button is AFU, I figured out I can still access the main recovery menu (the vol down to choose, vol up to select one) by holding down the vol up/down and plugging the phone into a charger. Same thing: power cycles off and stays off.
* Funny thing is although my power button doesn't work, I can still soft reset the phone by holding the power button in and vol down - which is what I need to do to exit recovery or other menus I need to input to a prompt using the power button.
Anyone know of this happening? MY guess is since my phone starts and functions normally otherwise, the boot loader is still there in some form. I just don't know how to access it. Any help would be much appreciated.
I can confirm this app will reboot bootloader

Thanks Dave but not for me. Same result: phone power cycles off and just stays off when selecting reboot bootloader.

If there is no bootloader you won't be able to start your phone at all as its THAT what basically boots the whole hardware and software....
How about adb reboot bootloader or adb reboot recovery commands ?

The bootloader being the phone's "bios" is kind of how I understood it so I'm figuring it's still gotta be there. I just can't seem to access it or get to the "device/battery OK, device disconnceted" menu. I tried adb reboot bootloader and got the same results: power cycle to off and stays off. adb reboot recovery works fine.
Knowing this phone is going to be turned back in, is there any other way I could re-install .211 without having access to the bootloader screen?

Try the eternity project flasher or the motorola's rds lite if they will be able to put the phone to the flash mode as they do that automatically...

I posted a thread over at DroidRAZR.com and got some good feedback and troubleshooting help. It looks like the bottom line is the power button failed in the 'on' postion. One of the folks that replied to the DR thread caused his device to show the same 'AP Fastboot power-off' that I was getting by entering the 'Boot Mode Selection Menu' and holding the power button down while he vol+ to select AP Fastboot. It caused me to look a little closer at what the device was doing and that seems to be exactly what's going on - I powered th phone down using the Quick Boot app and was able to soft reset by holding down the vol- key by itself (didn't need to press power in conjunction). After it SR and i released the vol- key, the device rebooted by itself.
For your info, that thread is here: http://www.droidrzr.com/index.php/topic/3782-cant-access-boot-loader-menu-no-matter-what/
I tried working a thin piece of paper in around the button but no luck there.
Just got a replacement phone from Sprint and have activated it.
Wanted to do a simple HTCDev.com unlock for the ability to do a few things that require root..
From being powered off, I hold down the Down Volume and them press and hold the Power button but that doesn't work... The three icons (buttonless buttons) flash a number of times but no matter how long I hold down those two buttons, the phone won't boot into the bootloader.
And YES, FASTBOOT is unchecked ....
Any ideas? I've rooted a number of phones and it's usually the 'hold down the down volume + power' until it boots into the bootloader...
Not this one...
HELP!
Turn off fastboot in settings and if you still can't, use adb tools or sdk and type adb reboot bootloader

Thanks for telling ! I had been looking for this information for a long time.
Apparently, my service info says "bootloader unlock allowed: yes", I wonder if it means that I actually unlocked it or that the device would accept me to do it.
I moreover wonder how one can manage to install CM or root its device without using Recovery Mode. I saw on your signature you rooted your device. May I ask how you did that ?

It means your bootloader CAN BE unlocked.
To install a ROM, such as CM, you first unlock your bootloader, then move the ROM zip to your device. After that, you flash the included kernel from the zip with fastboot. Then, you boot into the included recovery from the kernel and flash the whole ROM.

I finally found a solution to my problem : I unlocked the device using flashtool-0.9.11's gui procedure, instead of flashtool's fastboot. It succeeded and I can successfully flash anything I want on the device.
I found your rational approach to my problem useful. It helped me isolate a solution. Thanks !

Press and hold the Power and Volume Down keys for 10 seconds.
The device will reset and restart.
Hello everyone, I have a HTC desire 610 here and I cant get into recovery or fastboot. I've tried holding vol down + power and every other key combo, and it just boots up like I'm not doing anything. The buttons work once the phone is booted so I know they're not broken. Is there any other way to access these options? What could I be doing wrong?
One forum post mentioned a fast boot up option in settings that may disable the fastboot and recovery options, but this doesn't make much sense since this would mean you have to boot into the phone (assuming its working) in order to recover it.
Any input would be appreciated.

Having fast boot turned on in settings doesn't make it impossible to enter recovery or fastboot but is does make it very difficult. It removes any delay at the start of the boot procces and skips some checks to speed up boot time, but this does make entering recovery manually really hard. If you turn of the fast boot mode (I think it was under battery in settings but I haven't used stock rom for so long I'm not sure) you will find it much easier.
Your other option is to enable adb (go into settings > about phone > tap on build number 7 times to enable developer options > hit back > hit developer options then enable adb. Then install "minimal adb" and htc sync(to install the drivers) then from cmd line type "adb reboot recovery" to enter recover or "adb reboot bootloader" for fastboot.

Thanks for your reply. Unfortunately, i cant get into the phone settings because its password locked. I bought it at a police auction with a lot of other phones. Most androids are easy enough to restore but this one is giving me the issue i posted about. I guess ill have to keep trying the volume buttons and power.
EDIT: I was able to get into the recovery menu immediately after posting my reply. I did it by holding vol up+ power while the phone was powered on, it gives you a countdown then restarts. At this point to switched to vol down+ power and it kicked me right into the recovery menu.

There is another way to go to recovery option... setting>power>uncheck fast boot.
power off your phone ... the press and hold.. (power key + volume up key + volume down key) together......

I found a way for my 610:
Hold power+vol up ,then when screen goes black and vibrates, stop holding power on, move to vol down before appears htc white screen and then will go into fastboot mode. Guaranteed.
Tried cydia impactor
Thanks it helped

If the phone has a removable battery, remove it for 5mins and insert and try again. If that doesn't work, try using mtkdroidtools, it should work for your mtk model. If not, please reply as soon as possible with log cat.
