Desire/Bravo bootloader/fastboot

I was wondering if anyone has already posted or knows about the bootloader/fastboot in the Desires?
Holding VolumeDown+Power enters the HBOOT mode :-
HBOOT
FASTBOOT
RECOVERY
CLEAR STORAGE
SIMLOCK
Click to expand...
Click to collapse
Selecting FASTBOOT enters the FASTBOOT mode :-
FASTBOOT
BOOTLOADER
REBOOT
REBOOT BOOTLOADER
POWER DOWN
Click to expand...
Click to collapse
But what does RECOVERY/CLEAR STORAGE/SIMLOCK do?
And are there any other key combos?

recovery takes you into the recovery image (What you got to on the hero with Home + Power)
Simlock gives you the ability to modify the simlock status of the phone if you have the necessary software loaded on a card, or at least that's what it suggests from the text that comes up when you select it.

How long does the recovery take? I managed to seriously **** up my phone today. I got the message "com.htc.launcher has stopped working and needs to be shut down", or something like that.
I pressed the home, ok and back button at startup to enter the bootloader.

Cant enter recovery or download mode

Hello.
I flashed one KDZ for my country and root my E987. I also used freegee to install CWM (it should unlock boatloader I guess).
The problem in that when: phone turning on, trying to enter recovery, fastboot or download mode I have nothing but a black screen.
The phone is working perfectly.
In freegee I see these options: Backuo and restore EFS, Re LOCK and CWM/TWPR installations
What can be wrong??

In Optimus G (E975), should turn of phone completely (press power button for 10 seconds), then press vol up + power to start phone in bootloader. Then press vol down twice and then power button to start recovery.

I tried again but nothing but a black screen

So, if you can even access to your bootloader with vol up + power , you can connect phone to PC and flash a recovery image file via fastboot adb. (put your recovery image file in fastboot folder and then open a command prompt in that folder and type:
Code:
fastboot flash recovery recoveryfilename.img
Also maybe on your black screen you can do this.
If not, disconnect phone from PC, turn it off, press vol up + vol down together and connect USB cable, you may see download mode. if you see download mode, following method may help, but I'm not sure about E987! I did this on my phone E975 and it works: http://forum.xda-developers.com/showthread.php?t=2249500
Please consider it may remove all your data including system, userdata, sdcard , etc.
Good luck friend

Your welcome
If you could flash kdz means you can access download mode so you can try that method I've said.
Also you can download recovery images from following links :

Your welcome say thanks to autoprime that makes tinybin
Please remember that after tinybin you may see black screen and can't boot android. But fastboot and recovery should work and you can push a flashable zip ROM and flash it through recovery.

HELP blink sleeping android error on normal boot(not on recovery mode)

I can't boot up my device it's have blink sleeping android error. (my device is ze551ml running WW_2.19.40.22 firmware and never ever ROOT!!! )
I tried hold power button and press volume up button but its doesn't work.
I also can't access to recovery mode too.
It's have the same blink error message and can't pass by hold power button and press volume up button.
Oh but i can access to fastboot page.
and my computer don't recognize my phone at all(i already install driver)
Before this problem happen I get in to recovery mode try to wipe cache but i miss press and i selected "apply update from adb"
and that time my phone doesn't connected with PC. I don't know what to do so I turn off my phone.
then I open recovery mode again and select wipe cache then I go out to take a bath.
I came back and see my phone is off so I boot it.
It's booting about 2-3 mins and nothing happen so i go to recovery mode again but this time they have problem like i explain before(blink error message that can't pass by hold power button and press volume up button)
So anyone have a solution for my problem. please I really need your help!
Sorry for my bad english

Hi,
I had this when I went to wipe my system cache and it failed. Your best bet, especially if you can't get into recovery is to fastboot flash the recovery again if you have an unlocked bootloader.
If you don't you'll want to unlcok the bootloader and follow the instructions for using ADB if you're new to it: http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

How can I unlock my boot loader when i can't even open up my phone.

If you hold volume down and power, it should go to bootloader first, then you have your choices for recovery....Get it to the bootloader screen, then run the commands to unlock it...

Could you please tell me everything step by step on how to cure my phone?
I'm very noob.

okay thank you.
I can start it now
THANKS!!!!!!!
p.s. i use fastboot erase cache code

Glad you have it working...It seems that wiping the system cache can be problematic at times - Perhaps it's a bug.

Hey I'm having the same problem, how'd you get the computer to recognize that the phone was plugged in? My computer does not recognize that the phone is on when I have the flashing error screen, so ADB doesn't recognize that there is a device connected.

Hi,
I had the exact same problem, and I managed to boot up again thanks to you!
What I did :
Install ADB and Drivers
Boot my phone into Fastboot (Power+Volume Up at boot, keeping VolumeUp button pressed while booting). Don't go into any menu (do not select recovery or so). At this point your computer should recognize your Android phone when you plug it in through USB.
Open up a cmd with admin rights, navigate to adb install path by typing : cd C:\adb
Then type : fastboot erase cache
It should trigger an action on your device, and the prompt should display sth like "Cache successfully erased" (I don't remember exactly)
Finally type : fastboot reboot, press volume up while booting again, and access Recovery like usual!
Now you can try wiping your partition cache again.
Worked like a charm for me! Thanks a lot

Stuck in recovery after ADB with broken power button

Its very complicated. My T705's power button was damaged by water. And i flashed Stock MM rom with odin. It was fine after flashing, the tablet boot into the os properly, work very well in the os.
But then i want to wipe the cache and data after that, so i was using the code"adb reboot to recovery" to get into recovery mode because my power button was broken. (I thought it can be using home button to select in recovery mode)
But the nightmare is i can't select anything in recovery mode which requiring a power button. So i can't wipe the cache, also can't select the option to reboot my tablet...... I've tried to hold both the volume down and home key to go to the download mode menu, and select restart by holding volume down, but it go to recovery again even after removing the battery, i think it's because the adb command.
And the strangest thing is i can't use my volume up button in download mode menu, so sadly i can't flash the rom again,:crying: but the volume up is working well in recovery and in the os......
Is there anyway to prevent the tablet to boot into the recovery again? I'm quite sure it's not the problem when flashing MM rom, the problem should be the adb command makes my tablet boot into recovery until i change the boot setting in recovery mode.

Holding vol down + home key can boot to the download mode menu.
But the device will automatically turn on after inserting the battery, no need to press any button, but the device only boot into recovery after i use the adb boot into recovery command.

If that's the case that means the power button is stuck on or you wouldn't be able to power on or boot to Download mode.
All you need to do is flash the stock firmware or twrp and it will reboot back to the OS.

Hopefully I've got your fix:
When you insert the battery your device boots up, if so, insert the battery and press the correct key combo while the splash screen from logo.bin is showing to boot into the download mode.
After that flash TWRP latest version with Odin. Then when your phone again boots to recovery, chose Reboot -> System to boot Android.
---
If the above isn't applicable and you can start Android somehow, I will download either FlashFire or MobileOdin to flash another recovery/ROM.

So if you cannot boot to bootloader by pressing power and volume down at startup, you can try to enter recovery by pressing power and volume up. Then if it says no command hold the power button and press volume up one time. Now you should enter recovery. then from here you can try to enter bootloader.
Then flash your image via Miflash

the point it is, how can i flash via MiFlash, even they request the bootloader unlocked, when I begin the flash, they show the error, that nothing can do because the bootloader are locked, the program can't do nothing, i open device, initializing the phone on EDL mode, but, when flash system is done, from edl mode, they stuck on boot loop.

I can enter the fastboot mode, I can enter the recovery mode, but the device does not respond to anything and gets bootloop

Ok, you said you can enter edl mode even the bootloader is locked right?
How did you do this? You said you opened device, did you short the two test points. I have a similar Problem.

Seems like there are other Posts with different problems at the beginning which are now facing the same problem as we do, after some flashing:

EASY FIX for this problem!...go again into fastboot mode....POWER button + Volume DOWN - in the command prompt on the PC type: fastboot oem unlock
system erases all the data and starts again had the same problem! i installed magisk to enable camera2pi, so today i got the mi mix 3 and i thought hmm lets lock the bootloader mi a2 lite and erase all the data so i can pass it further to my mum and she´ll get fresh updates! unfortunately, when i did fastboot oem lock, it said "system .blablabla..destroyed" ! Now everything workds fine again!

You can also flash stock rom with Miflash tool and choose the option at the right bottom to "clean all and lock" after flashing you've got stock rom and relocked bootloader
