You need a Windows PC, I suggest getting minimal ADB from this XDA post.

[Q] I can't access Bootloader or Recovery PLEASE Help!

My HTC One M8 (Verizon) is seemingly bricked. My phone is rooted, S-Off, with the stock ROM. I have been trying to update to the latest OTA update by returning to stock. I had previously modified some entries in the Build.prop and Platform.xml. I knew those had to be default in order for the OTA to work. I had copied the original files and pasted them to my SD Card so that I could simply cut the modified versions, paste them to my SD Card, and cut the originals from my SD Card and put them in their corresponding system folders.
Upon a reboot something apparently went horribly wrong because all my phone does now is boot with the white screen and green HTC Logo, then the screen goes black. I have tried the typical Power Button + Volume Down but it won't enter the boot loader. The good news is that the USB port seems to still work for my windows computer recognizes a device connecting to it but it doesn't show up as an interactive device in windows explorer..if that makes sense.
Please Help!

When you connect it to the PC can you pick up the device with adb? If so, have you tried to run the command from adb to boot it into bootloader? adb devices ... if found, adb reboot bootloader
:fingers-crossed:

I'm not too familiar with ADB commands but I typed in "adb reboot recovery" and it said: "error: device not found" so even if my command was wrong it's still not detecting it. I also tried: "fastboot reboot bootloader" and it just says "waiting for device"
Also I feel like it's worth mentioning the phone is automatically rebooting every two minutes or so (haven't timed it exactly but it's a while). Still showing the green HTC Logo then the screen goes dim, then the screen turns off.

Try holding volume UP + Power button, this simulates a "battery pull", just hold it in for a while it can take a while to "pull", when it's off try again booting into bootloader, volume DOWN + Power button.

I held Volume Up + Power Button and it showed the white screen with the green HTC logo. I then released all buttons. Once the screen turned off I then held Volume Down + Power Button for two minutes straight and nothing happened.
Even though we haven't found a solution yet, I am appreciative of the help.
sounds like you never installed the htc drivers for your phone, hence your pc doesn't see the phone when you are doing ADB commands.
install the drivers for it, then try the ADB commands via your pc
and dont mess with the build prop or other system files unless you have a working back up and are 101% certain about what you are doing..
Just remember to change directory in command prompt to the folder where adb.exe is located.
I don't know why the device doesn't reboot into bootloader though when you hold volume down + power button, shouldn't have to hold it for 2minutes. Holding volume up + power button to simulate a "pull" should only take up to 20 seconds or so at most and pressing volume down + power will then immediately take you into bootloader mode, or at least it's supposed to.
Did you release the volume up / power combo when the screen went dead or before? Try holding it until the phone shuts off and then right away press volume down + power.
Sorry if I'm not answering right away though, busy eating, and will be here and away for the next hour or so while I get ready for work =o( once I leave for work I'll only be able to help some more after like 2 hours or so. Hopefully we can do something before then though =o)

You're right, I didn't install the drivers. I did so and ADB was able to recognize it and I was able to access the bootloader. Thank you everyone for your help. I won't be making the mistake again.

So you'll be able to fix it from here on then? I was just about to link this thread to you as well should you have gotten adb to work again, it's for the RUU for Verizon seeing as you said you're on Verizon.
But going by your response up there you might already know how to fix this issue further :good:

Share another method of getting into recovery mode on non-responsive blank screen
Hi,
I just want to share how I accessed recovery mode with the same build.prop issue but with S-ON (might work with S-Off too).
I found the solution from here:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
To get into recovery mode on a non-responsive blank screen, hold the power button and volume up button at the same time and then approximately after 10 seconds, switch from pressing the volume up to volume down button before the HTC logo white screen shows while still holding down the power button. After, a white boot screen will give an option to go into recovery mode.

Completely unable to boot to download mode

Hi, as the title says I am completely unable to boot to download mode on my E988. I have literally tried every possible combination of button pressing but nothing works. I have tried rebooting to bootloader from cwm but that doesnt work either, all it does is reboot, show the LG logo, then it reboots normally.. I have tried using terminal emulator to use the command "reboot download" but it doesnt work either, all it does is reboot, show the LG logo, then it reboots normally again. It seems that I am completely unable to access it at all. Any ideas?
Have you try with one end of the usb cord already plug in either your computer or phone, hold down both volume buttons, and plug in the other end. This was the only way down load mode would came on for me until I fixed the phone.
Yup I have. No combination of keys and button pressing seems to work for me it's odd.
Sent from my LG-E988 using XDA Free mobile app
To add on to my previous post, when I do the method whereby I hold vol + and vol - and plugging the usb cord in without my phone's battery, a message shows up when it is detected saying that a "...usb device has malfunctioned...". My phone will then just keep showing the lg logo over and over again causing the message to pop up again and again as the phone is detected and then not detected and the cycle just repeats itself. I have tried to reinstall lg drivers but nothing seems to work...
Edit: It would seem that the phone is indeed trying to boot to download mode whether I use the key combination or command, but it is unsuccessful in doing so and just reboots. Has anyone ever encountered this problem?

Cant recognize phone in fastboot!! HELP!!

The phone is in bootlopp (i think).When i turn on appears android on groundb with the red triangle and a chinese word.This disappears and appears again,for an infinite time.Display stays turned on.Turning on in bootloader it works,but just in bootloader.If i try to enter in "Restart bootloader,"recovery,"normal boot"ecc it's in bootloop again.So i can access only bootloader at the moment.I want to reflash system,droidboot imgs ecc with fastboot but...tried to recognize phone on an old HP Compaq nx6110 with usb 2.0 and win7.installed on it adb drivers,adb and fast-tools.don't think zenf2 drivers are important at the moment,now should consider just the adb drivers cause i can access only bootloader.however i think zenf2 drivers are installed on it.nothing.phone no recognized by fastboot and no recognized by windows.consider that on a xp and 2.0 usb pc (with fastboot,adb,and adb drivers on it) phone is recognized by windows as Android-Phone but then windows says i've not the drivers for the installation (appears the drivers' choosing window).No asus driver on it,on the win7 pc there are!!

When you see the dead android with red triangle, hold the power button and keep pressing it and quickly
press volume up button and release it but keep the power button and you will see the Recovery options.
Then choose "format Cache" with volume up & down button and enter with power button to format cache partition.
It would take a long time so don't be alarmed. When done, choose restart system and the boot loop should be fixed.
Good luck.

Didn't work for me ... if I keep pressed the power button for a long time, power off the phone and it doesn't entry in Recovery mode...
I resolved with "fastboot erase cache" command
It is normal to get that error when selecting 'recovery mode'
The next step is a little tricky. You have to press and hold the power button, then press the volume up button. It may take a few tries. Both buttons will have to be pressed together simultaneous to enter Android system recovery. Please also see http://www.asus.com/us/support/FAQ/1011956/

Hi,
I´m having a problem with mine. Can´t recognize phone in fastboot but it´s different. I already asked for help in general thread - all resources (page 47 to 50) but still can´t solve.
I rooted my device using method 3 (one click root) and first everything seems fine, but on my first reboot i entered on bootloader - recovery and started a wipe cache, but didn´t finished it, push power button and force it of (i seemeed stuck there - was wipping for more than 10 minutes). Since then i can´t solve anything, tried many ways to unbrick my phone but i seem the problem was i can´t connect fastboot. After a lot o tries, i entered in TWRP using method 2 and wipe, made a recovery, everything and as magic i can enter again on recovery, even tried adb sideload (it started, but when starts to write something - at 50% of the process just ended). So, long story short, i did a flash of the original firmware i downloaded from asus website using method 2 and now it´s working as original, but i still having the same problem (or maybe worst, since i can´t enter the TWRP recovery using method 2 anymore) and can´t root my device. When i tried to do anything using fastboot it´s just shows "FAILED", When i request adb devices shows a blank line. If my phone is on, using android, it shows the correct serial number.
I don´t know what´s happening, it seems to estabilsh a connection (when on its ok, method 2 freeze on teamwin logo - the tool can write something on phone) but can´t write anything. i´m worried because i think i won´t be able to do any update and i wanted a rooted phone to.
Anyone seems a solution?
I'm having the same problem today and I solved it just now! I can't even open the fastboot and recovery. Finally I install the software "shuame"(I'm Chinese, you guys may find other software) on my PC, and with it my computer read zenfone2, and I use the function in the software to open fastboot mode, then I flash the WW version recovery.img and boot.img with a one-click tool in zentalk(TW), then I just double wipe, the phone is alive now !

Need help using CWM to recover data

So my screen blacked out and I would like to attempt and retrieve the information off of my phone. I have an idea to use the CWM I have installed on my phone and from there mount it. But since I cannot see the screen, I was hoping somebody could tell me the number of presses of each button so I can mount it. Thanks!

not sure if cwm will help, but twrp 3 will definitely help, i want you to boot into download mode and flash twrp 3 using Odin, and then boot into recovery.
TWRP 3 has MTP enabled by default, so when you're in TWRP and connected your phone to PC, you will see your phone on PC and will be able to copy anything you want.
also you can use adb pull commands but it requires usb debugging on in your rom.

yes, you will do it blindly, but it's not hard.
you press power + home + volume down for 3 seconds, then press volume up, and connect your phone to PC, then flash the TWRP 3 using Odin,after the flash is done, remove battery, and insert again, then hold the power + home + volume up for 4 seconds, the release the power and keep holding the other 3 buttons for another 3 seconds then release, by now it should be in recovery mode, now connect to PC and you should see your phone and all its content.

good question.
he can't do it in two cases:
1- if he is using android 6.0+
2- if he is using a password, PIN or a pattern in his lock screen.
i believe he should have tried your suggestion already, it would be a shame if he didn't because it's an Obvious thing.
however, i should have mentioned that as well...

N7100 boot stuck

Hello.
I own a Note II which lately seemed to have some problems.
In the last few months, it used to restart somewhat spontaneously (it seemed that it rebooted when its processor or RAM were too busy, but this wasn't a rule). During one night it probably rebooted and next morning I found it stuck on the first boot screen (the one with "Samsung Galaxy Note II").
When stuck on the boot screen, if I press the power button for a few seconds, it turns off. If closed, it gets to the boot screen and gets stuck there when I press the power button. When plugged to power, it gets stuck at the screen with the empty battery that has a loading icon in the middle.
I manage however to get it into recovery mode, however, in this situation, it can't be seen by the PC, unless I put it in adb sideload mode. When stuck on the logo screen, it is seen as mtp device.
In the recovery mode screen, there are many errors (can't/failed to mount /efs, /system, /cache, /cache/recovery/last_recovery, /data, /data/log/recoverylog.txt, /cache, /cache/recovery/log, last_log, last_install.
In Windows, the PC doesn't recognize the model, however, in a virtual machine that runs Linux, it is correctly seen as Note II when in adb sideload mode, but Linux is not able to mount its storage.
I have also deleted cache, tried Samsung Kies and Note II Toolkit.
What I would like to do is recover the data on it. Do you think it is possible, and if yes, how?
Thank you.
Sounds like a failed memory chip to me.
any answer now?
i want get ROM-not2-7100
Can you make it more clean and what do you want ? I want help to you but i dont understand what are you talking about So can you have acces to twrp ?

No, I don't have access. What I want is to recover the files on it, if possible.
This may be a problem with the power button. if you can go into download by pressing only the menu button + volume down is because the power button is always pressed.

Sorry i think your partitions broked. I think you cant recover your data. There is has only one solution. Odin and Format....
My device too has pc cant detect my phone. I tried different cable without samsung usb drivers. Pc succesfully detected the my device.
By the way i installed lg usb driver because of someone's phone is lg and they need format.
I think there's no way to recover your data now.
BTW what recovery are you using?
