As it happened with me, it could be that you decided to unlock your bootloader and then while flashing some mod meant for a 'stock' device, you got stuck in a bootloop or got stuck at the splash screen (HTC/One X logo).
Through this tutorial, I'll try to help you out.
How to get into fastboot
Keep holding the power button.
After about 5-6 seconds, you'll see the touch buttons blink and the phone will reboot.
As soon as the screen goes off, hold down the volume - (down) button.
You'll enter bootloader.
Connect your phone to the pc
Navigate to the fastboot entry by using the volume keys
Enter fastboot by pressing the power button
Simple things first -- Erasing the cache
Go the folder with your fastboot executables
Type:
Code:
fastboot erase cache
Reboot
If that didn't work, keep reading.
Now there might be an easier and more involved solution out there, but I couldn't find it when my device was unbootable. I'll just tell you what Jotha advised me to do, and which worked for me.
Flashing a ROM will probably solve your issues, but the problem comes when you realized that you don't have a ROM on your SD Card to flash. Since the current version of CWM does not support USB mount, we need to get the ROM on the phone through some other means.
Putting a ROM on your phone
Try ADB (if you get a device not found error, read here: http://forum.xda-developers.com/showthread.php?p=25879200#post25879200)
You can transfer the ROM to your phone by using ADB.
Try the command:
Code:
adb shell mount /sdcard
adb push <path to rom> /sdcard
This will copy the ROM to your card (it could take a while).
Now simply boot into recovery and flash the ROM.
Hope this helps.
Very Good. Congratulation.
just want to say thanks..!

Hi, My DHD volume buttons no longer work and I've been reticent to send it off to get fixed as I can do with out the volume controls as opposed to being without a phone for 2-3 weeks.
However I used Rom manager to boot into CWR and was in the process of upgrading to revolution 5.2.4 from 5.1.8.
I ran the full wipe script then my fat fingers rebooted the phone rather than flashing the rom.
I now cant get back into CWR to flash the new rom. It just sits at the boot logo, obviously as all other partitions have been wiped.
Is there any other way I can force the phone to boot into CWR, perhaps using the sdk tools or similar?
I've tried adb devices, but it doesnt show up. Is there an external way to force the phone into flashing a new ROM or booting into CWRM ?
Thanks
Ron
I would like to help, first lets try using adb, command would be adb reboot recovery
Hi, thanks for the help.
As mentioned in OP. I have powered the phone on and have have already attempted this, but the device is not recognised by adb.
tools>adb reboot recovery
error: device not found
My question is how to get the device to be recognised if its simply sitting at the boot image?
R
Sorry I over looked that, it seems to me if adb (which is an sdk tool) won't recognize the device as being attached, i don't see any other sdk tool doing any different, also as far as I know there is no alternate method to scrolling through the boot loader that would allow you to choose recovery and flash a zip other then the volume keys , so it seems the solution is, to send the phone off, get the volume keys fixed, and then you will be able to get back into the boot loader, and select recovery, and reflash a rom. Other than that, I don't see any other method, if adb doesn't recognize the device as being plugged in, I am assuming you attempted to boot into boot loader as well, and see if adb recognized the device?
EDIT: stupid question you can't boot into boot loader without volume key
I just want to confirm that I need do nothing else other than configure the sdk and ENV path etc, such that if i can run adb and get the deafult output, eg switches fr command line options etc...
then all I should need to do is turn phone on and connect via usb to computer. I dont need to edit any config files for specific phone versions or whatnot?
If not then Ill try and bring it to a vodaphone shop and see if they can fix the volume button...
R
if you get the volume buttons fixed, we don't even need adb, I was simply thinking adb since your volume buttons are broken. Once the volume buttons are fixed, you simply need to boot into boot loader, then to recovery, mount USB mass storage, put a new rom on there, wipe the phone, flash the rom and your good
Good luck mate, do some mediation meanwhile and learn to keep patience, so when your phone is back, you can treat it gently while in the recovery.
You will be alright once your vol keys are fixed.
I rooted and installed an ICS ROM several months back on my Fire. One morning the wife brings it in and says my son got it stuck in some weird mode. Turns out it is stuck on the TWRP yellow triangle and does not seem to be able to get into recovery mode. I have done that several times before so I am pretty confident I am not messing that up. Just the power button never turns orange and eventually the device just turns off. My computer see the USB device but ADB does not. I did `android update adb` and then added '0x1949' to '~/.android/adb_usb.ini'. Do I have any options left or is it bricked?
Thank you to anyone who takes the time to read this. Especially to any who can reply with suggestions.

ADB will not work because you're in fastboot mode. Use fastboot commands to install the new TWRP and change the bootmode.
Code:
fastboot flash recovery /path/to/recovery.img
fastboot oem idme bootmode 5001
Hold the power button to perform a hard shutdown and restart the device. You should then be able to launch recovery using the power button. If not, you'll have to flash the bootloader as well. If this is the case, be extremely careful you don't pull the USB cable during the flash or you will really brick your device.
Also, it is very important to know that the version of FFF you'll download comes in a .zip format to be flashed in recovery. Don not flash the .zip file directly to your bootloader partition. Instead, unzip it and find the "fff-u-boot_v1.4.bin" located in the cache folder and flash it.
Code:
fastboot flash bootloader /path/to/fff-u-boot_v1.4.bin
fastboot reboot
If you were able to access recovery just by reinstalling it with the first command, push the FFF1.4.zip file to your sdcard and flash it in recovery. Just remember not to wipe anything before installation. That will help you to fix your bootmode problems a lot easier in the future by holding the power button untill the boot options appear at the bottom.

Thank you! I am back in recovery!
hey guys,
i was bored and flashed a .zip on my phone and now I'm no longer bored. Long story, short... I'm booted into the os (almost) with constant errors popping up. I can't get the power button down for 10 seconds to reboot phone and i want to get back to recovery to flash by back up. How can I use terminal (mac) to force back into recovery if phone is not in mode for adb to recognize phone?
Thanks in advance.
Try hold power button + volume up to force reboot. Once the screen goes black release those buttons and hold volume down button to go to hboot
Thanks for your reply. Seems the power + volume is not be recognized. Is there a way with fastboot or adb?
Otherwise, I guess I wait until power drain.

Power + Volume Up should work. But as you asked for adb/fastboot
1) "adb devices" to check if device is recognized
2) "abd reboot bootloader" so the phone reboots into bootloader
3) go to recovery and try a reflash

This should always work as long as the screen is on. It might take 10 seconds or more, so you may not be holding the buttons long enough.
Alternately, you can use:
adb reboot bootloader
or
adb reboot recovery
There is no required more for adb commands, as long as the screen is on. Fastboot on the other hand, requires the phone to be in fastboot mode.
What did you flash? Was it a ROM, and if so did you do a full wipe (data, cache and Dalvik) before flashing?
Thanks for all the replies. It finally died and I was able to jump back into recovery. I was trying to flash a .zip (one+ one theme) to my rom and some things about it (audiofx) was not liked. I guess adb could not recognize the phone since it was basically booted into the os. I just thought there was a way to still use adb or fast boot to push it into recovery. I did not get to try adb reboot boot loader, but would adb recognize phone even with this command?

Sent from my HTC One_M8 using XDA Free mobile app

I tried hold power button and press volume up button but its doesn't work.
I also can't access to recovery mode too.

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.

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

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
So I already had a rooted (and I'm pretty sure unlocked bootlader) version of the stock Asus and wanted to put CM13 nightly on there. Everything was going smooth until I got to the stage where I have to load into TWRP and I got the error screen with the little dead alien and the red symbol.
Now I can't enter normal boot, but entering recovery mode seems to work. I tried the option to side load a package from ADB on that screen but nothing worked (.zip files extracted, but I got an error on the phone).
As you can tell, I'm really new to this so any help would be greatly appreciated. I tried looking around, but it seems the more common issue is people not being able to enter recovery mode or something similar.
Thanks
Looks like your doing it wrong. Being rooted does not necessarily mean that your bootloader is unlocked.
By the looks of it your in recovery mode with the dead robot with the "error" message. That is normal. To reboot back into system you either have to press (I don't remember) power button and volume up or down button. Then you should see some options with reboot to system. Or if that does not work you can hold the power button till it turns off.
Then you get back into Android, download the official bootloader unlock tool from ASUS and install it on your device. NOTE: If you updated to MM then this will not work and this will void your warranty.
Run the tool and press unlock and it should reboot into fastboot where it should begin the unlocking process. I believe it should automatically reboot and you should see that the Asus logo is now black instead of white. If not, repeat the process.
You can now proceed to flash twrp recovery. Boot into fastboot/bootloader mode either with "adb reboot bootloader" or hold a specific set of buttons while off to go directly into fastboot.
On the computer, connect your device and type in "fastboot flash recovery (path to twrp IMG without brackets)"
When done you should be able to reboot into twrp recovery where you can flash the cm13 zip.
Hope this helped.
