Hello Guys
After doing deep search on this forum and try several unsuccessful solutions (recover mode, fast boot...). I decide to create new thread.:angel:
Symptom : A boot loop on Android Upgrade (There are 7 updates to apply).
I think, I know the cause but every solution found on this forum didn't succeed.
I tried to access recevey mode ( Power+Up, then release up ). --> When I release Up after vibration, I don't enter into recovery mode.
I tried to access my phone through fastboot or adb but, I have following message : "Wait for device". No detection so
Here is what I have done to be in this situation :
I've rooted my phone (thanks to forum explanations) --> No Problem
Installed this bull**** app "App Master" to freeze or put bloatware into trash (recoverable)
Everything was ok, since I noticed "Asus Start Manager" needed to update but was not compatible with my device. Strange isn'it.
So I've undertaken to restore frozen and removed app from app master. It asked me to restart and then, my 7 restored app seems to involve a big mess.
And now I can't Boot. NOte that android upgrade wants to suprisingly update 7 optimisations.
My next idea is to acces directly internal storage to remove 7 apk provoking boot loop.
Do you have better idea because if I remove internal storage, wararnty will be canceled and in addition I have no guaranty I'll able to read it.:crying:
Further more I hesitate to send it to vender since my device is rooted. They will answer it's my fault, and it's true sic !
As you understand I 'm quite desperate . IF someone can help me I'd be so grateful.
Thanks everybody and sorry for my english

Unfortunatly no.
bouhhh !!
Try to see here http://forum.xda-developers.com/zenfone2/general/unbricking-research-unbricking-method-t3162848
Ok i'll try it after work this evening.
I have nothing to loose so....
can u let me know. I failed with it.
U should have been able to access the boot loader at least.
while pressing and holding the volume up button , press and hold the power button until the set vibrates.
just when u feel the vibration RELEASE THE POWER BUTTON, NOT THE VOLUME UP BUTTON, 9as u have mentioned the oppssite in the first post) then it should go to boot loader menu.
I have a similar problem with ZF2. I access recovery mode by pressing the down arrow key and then the power button but the phone just reboots into recovery mode again. No dead android logo appears as others have suggested.
Try that : http://forum.xda-developers.com/showthread.php?t=3191244
Do volume up + power, once it vibrates press volume down rapidly about 3 times. Wait for a minute or two while on the Asus screen. Sometimes it will boot into recovery or it will vibrate and stay stuck. It worked for me.
A workaround
Hello Guys !
I've posted a workaround to my problem but I don't understand why it doesn't appear. I certainly made a mistake something.
Here is what I remember:
I tried several procedure described on asus-zenfone.com I finally found a soft which unlocked my recovery mode.
But finally it was maybe the fact to connect my device with usb which unlocked It (sorry I don't remember)
Once recovery menu was available, I downloaded official rom, copied it on an sdcard and installed it.
Good news, most of bloatware were desactivable !
Now, I have a device rid of the unworthy softs with an offical ROM.
In such situations I usually disassemble the phone and disconnect the power train of a few minutes. After that it booted recovery/bootloader.

I am able to access bootloader . But when i choose recovery mode, the phone enters into a boot loop.
. Here is what i have done:
1. My device was already rooted.
2. Tried to install twrp custom rom using usb adb commands
3. It showed successful. I fast booted into my device. Switched it off and entered boot mode again. then selected Recovery. But I was never able to enter into recovery (The Robot with error was not at all displaying).
4. Then i searched google and found my boot loader was locked. I unlocked bootloader using
https://dl.xda-developers.com/3/4/0....zip?key=dEgXp67KVlqwn4BL-w1kWw&ts=1505837086
5. Now my flash screen is in white background. I can enter boot loader.
6. Then again i installed twrp via adb and selected recovery mode. But when i choose recovery, the phone goes into boot loop.
Please help.. One doubt: MY Phone is ASUS ZENFONE 2 Z00AD.

I had a similar issue but was able to get into recovery mode and restore a backup.
Can you get to recovery like this
Power Down the LG G4
When Off, Press and Hold the Volume Down and Power Buttons at the Same Time
Continue Holding These Two Buttons Until You See the LG Logo
When You See the LG Logo, Let Go of the Volume Down and Power Buttons for 1 Second
After 1 Second has Passed, Immediately Start Holding the Power and Volume Down Buttons Again
Continue Holding These Two Buttons Until You Boot Up into the LG G4 Recovery Mode

Hi I'm sorry if you've already said you can't get into recovery mode or anything but when i bricked my g4 i used the lg flash tool to flash h815 10c stock and then instead of flashing the latest twrp (the blue themed one) i flashed the one before it which is 2.8.6.1 and it worked perfectly so if you manage to get into recovery or fastboot then try and flash that version of twrp instead , good luck buddy...

How did you "brick" (it's not) it? Kill switch is an anti theft feature, usually triggered remotely by the user.

This button combo you posted is wrong any way...you only release power for 1 sec and continue holding vol down and the re press power
I cut and pasted those instructions from another site. They held me back from fixing my phone for hours until I discovered the method you have mentioned. I haven't seen any site that tells us to do it like you said, I just was trying different ways and then hey presto!! it worked.

Hello,
My friends own an htc m8. A non professional lab has flashed him Android Revoultion Rom (without making a wipe, he used to use stock rom before that)
Since than the device suffer from a lot of problem,we would like to flash a stock rom.
What's the problem? the device refuses to go into bootloader at all & than refuses to turn on, only after a while in the charger it does turn on.
But any attempt to make the device go into the bootloader, has failed.
tried also RUU - it won't load the bootloader, and the pc recognize him as QHSUSB_BULK if the device is off, which is soft brick as far a i know.
The device actually turn on after a while, than when i connect it to the PC, the pc does recognize him normally.
What's the best option to flash a recovery and a stock rom?
Thank you.

There is definately some information missing here. Flashing a ROM without wiping will never get you into this state, unless maybe the ROM was meant for a different device.
It sounds more like a deleted bootloader partition, or borked eMMC.
It's bricked. You need to take it to a shop to see if they can JTAG it back to life.
Sorry.

Hey,
We don't know what they have done exactly
They device does turn on after a while... Can i just flash the whole bootloader through the computer anyhow? If the device is on, the computer does recognize him and i can use adb/transfer files.
In a few minutes when the device will turn on i'll write the software information

Have you tried turning off the phone, and booting it by holding down power + vol down? That should take you to bootloader. It's not bricked if you can boot it.
Tried that already...Doesn't work. The device refused to turn on that way.
Tried also through adb/an app when the device was on (yeah it's rooted), than the device turned off and the computer see it as QHSUSB_BULK.
Than i have to plug it off the pc, connect to AC and after a while it's just turn on by itself....

Not sure about this. If you didn't have a bootloader, I don't think your phone would boot at all.
It does boot, but not normally.
Anyway, there's no way of getting into bootloader
Did you enable developer options and within those option check USB debugging, so it's enabled. If not got to "settings > about > software information > more" and tab the build number entry several times until you get prompt the developer options have been enabled. Then got to developer options and check USB debugging. Try running the RUU again. Many this already works. Otherwise we'd have to look further.
Send by the swarm intelligence of my coffee machine ?.
I hgve already enabled dev options. once the ruu tries go get into the bootloader, the device just turn off and i can see on pc device manager it's QHSUSB_BULK

Meaning what, specifically? Stuck on HTC logo screen, or something else?
As long as the screen is on (on any screen), you can:
1) Hold Power + vol up for 20-30 second, which will force a reboot.
2) The moment the screen goes dark, let go of those buttons, and only hold vol down. Don't let go until the bootloader appears.

I'm still confused about what you are describing, and I think others trying to help are confused also.
You said the phone boots, but not normally. I asked what that meant specifically (which you did not answer at all). Stuck on HTC screen?
So the screen is on, when you try the button sequence I suggested? Then when the screen goes black to reboot, it just stays black?
Hard to help, if you don't provide details and specifics.
The phone boot and you can use it, that's how i have provided information from the settings. If i try to reboot, the device does not turn on. only after about 5 minutes.
same for bootloader. if you try to get into bootloader from adb for example, than there is only a black screen and after a few minutes it's just load the OS normally. but no bootloader.

So if you try the button combo I suggested, it eventually boots to OS? Are you still holding vol down when it boots to OS? If not, you should be (and let go too early).

What's the exact adb command? I'm sure you probably have it right, but just want to confirm.
It doesn't boot when i try the button combo... and after a few minutes it boot to OS.
also tried though an app because the device is rooted.... and also through RUU. The RUU restart the device and should make him to go into bootloader but it failes doing it.
adb reboot-bootloader
when the device is turned off the pc only see it as QHSUSB_BULK

It still really confusing how you are phrasing things "It doesn't boot . . . after a few minutes it boot"
Either it boots (just takes a long time; or boot OS, but not bootloader) or it doesn't.
Holding power + vol down makes it shutdown, right? Once the screen goes dark, hold only vol down and don't stop until you either see bootloader or the OS loads. Its not clear from the way you've typed it, but it sounds like you are pressing vol down for a while, then give up and let go, then it eventually loads OS.
I understand that it doesn't look like it wants to boot into bootloader, from any method. But we really need to eliminate all possibilities and be sure you can't do it with the button combo.
Its really unusual to see a device that can boot into OS, but not go into bootloader at all. I've never seen this once, after being on these forums extensively over the course of 4 different HTC Android devices.

Yes, Holding power + vol down makes it shutdown. After the screen goes dark, i tried to hold only vol down. nothing happends. tried to hold it for a few minutes. nothing.
When i release it, only after a few minutes, the device load the OS by itself (if i try to press the power button it doesn't work at all)

So how do you know whether releasing the button is a condition of it booting, or a coincidence?
For that matter, how do you know it won't go to bootloader if vol down is held when it finally powers on?
I'd say the answer to both those questions is: you don't know. At least, not for sure.
How long is a "few minutes"? 3 minutes? 10 minutes?
Maybe hold down the vol down button with some tape, if you can hold it down manually the whole time?
It's doesn't really Matter, as the adb/ruu/quick bot app should have be able to load the bootloader....

It does matter. As I already explained, you should eliminate all possibilities. At least I assume that someone who genuinely want to fix the phone would try every possibility.
You spent about as much time replying, as it would have taken to try my suggestion.
I agree, I don't think it will work. But you don't know if you don't try.

So the power button didn't work in OS before? But now it does in bootloader (assume it works, otherwise you would not be able to select the options in bootloader).
What does it say for OS number on the bootloader screen?

Unlikely. You should have been backing up your data all along; instead of wishing you did after a disaster strikes.

Hold power + vol up until your phone reboots. AS SOON AS THE SCREEN GOES BLACK slide your finger to vol down. That'll take you to bootloader where you can choose to boot to recovery. From there you can flash a ROM from your extSD.
EDIT: the option for recovery is under hboot
