Not only is my power button broken, but I can't access the device because the seller forgot the pattern unlock (haven't used in a long time, since he didn't know the power button workaround) and email won't work. How can I hard reset or access my phone in general?
Plug in the phone and 'adb reboot recovery'.
I doubt the previous owner has usb debugging enabled, so you may be SOL on the adb commands.
Try passimg, using the battery trick and volume down to get into hboot.
My device was not found in adb reboot recovery presumably due to disabled usb debugging, but the passimg method worked! Thank you very much!
Need HELP TOO
can someone tell me how you guys fixed the problem , i have the EXACT same problem with my nexus one, need to hard reset but no power button
You need download Android SDK to use adb command in cmd(windows).

If you have USB debugging on than use ADB like mentioned above.
If not use the passimg
http://forum.xda-developers.com/wik...des_&_Tutorials#Unroot_.2F_Restore_your_Nexus
to get your N1 on, try plugging it in with usb charger and remove/insert battery.
might take a few times but the phone might come on using this method.
Thanks so much for that link, the passimg method worked,
I have searched around for a couple days, but there doesn't seem to be anyone who has posted about this issue with a Droid 4. So here is what I have.
I rooted my Droid 4 using the RazrBlade method without incident. Afterwards I wanted to flash Cyanogenmod onto it, but did not have a custom recovery like ClockworkMod or TWRP set up yet. So, looking around led me to download the latest safestrap .apk so I would have a recovery capable of flashing Cyanogenmod. The latest version of safestrap would not work for me because of a parsing error, I looked around and found that some people were having the same issue and fixed it by downloading an earlier version of safestrap to their Droid 4. So, I found a safestrap 2.x.x version, downloaded that and followed the directions accordingly. I now had a functional (to my knowledge) recovery that would allow me to flash CyanogenMod. So I downloaded the .zip file from the CyanogenMod website for Droid 4, and attempted to flash it using the recovery that safestrap 2.x.x set up.
Everything looked okay for the install, no errors were reported, phone was at least at 80% battery, but once the phone rebooted, after the Motorola spash screen, there was a blank screen. The phone is on, evidenced by the backlight being visibly seen, but otherwise there is no evidence that it is trying to boot up any ROM. There is no loop whatsoever, just a blank screen.
First, I thought it was a bad install, afterall, it wouldn't be the first time. But when I turned it off (only possible via PWR&Vol.- button combo) it did not give the option to go into the safestrap recovery mode upon booting back up.
But I am not without a working knowledge of how to pull a phone out of a softbrick state, so I quickly connected my phone to a computer set up to take adb commands and tried to reboot my phone into the recovery mode. I connected my phone to my PC, left it on the blank screen mode and typed the adb command [adb devices] to confirm that it was acknowledged by my computer, it was, and attempted to reboot it into the recovery mode with the command [fastboot reboot-recovery]. It responded by rebooting, but led back to the backlit blank screen. I thought that this might be an issue with the wires or drivers or something to that effect, so I reattempted with a usb cord that was supplied by Motorola, and reinstalled all the appropriate drivers. Nothing worked, so I moved everything to a new computer freshly set up to take adb commands. I connected my phone and it was immediately recognized by the new computer, but it still would not respond to any adb commands. Attempting to reboot into recovery yields a blank screen still.
By this point I do not care if my phone is rooted or if I have to restore it to factory settings. So I look up solutions that flash it back to the stock 4.1.2 ROM. I find one that does this, but it requires that I am in AP Fastboot Flash Mode. I put it in the aforementioned mode, but it is not recognized by the adb terminal. It is listed as an adb device if it is in "blank screen mode" but not while in AP Fastboot Flash Mode. Shortly after this the battery is too low to program anyway, so I turn it off and set it to charge. But instead of a "battery charging" screen, I am greeted with the Motorola splash screen for as long as the phone is connected to the charger. Every time the phone is removed from the charger it, immediately and without pause, loses power and cannot be powered on until placed back on a charger.
Looking around some more, because I am increasingly desperate to solve this problem, I find something called RSD Lite, which will reflash the stock firmware to the phone and it will behave as if it was reset to factory settings. I plug the phone up to the computer, it powers on, I boot it up to the AP Fastboot Flash Mode and RSD Lite sees the phone as a fastboot device, and is ready and willing to fix it, but the battery is too low to program.
The battery is incapable of being charged by a wall outlet by any means that I have tried (will list below), BUT... If I connect my phone to a computer, and after the phone is connected, turn the phone off, a little green LED light appears at the top left and stays for at least 15 minutes until the Motorola splash logo appears and my phone connects to the computer. The phone recieves power in this mode evidenced by the fact that it does not instantly power down after it is disconnected from the power source. But at this point in time, the battery does not charge enough to cause a change in the AP Fastboot Flash Mode to allow it to be OK to Program.
Here is some misc info that might be needed:
Modes that I have access to
1.) Motorola Splash Screen + "Blank Screen Mode": This mode connects to the computer and is registered by the device number XT894. After the Moto Splash Screen there is a backlit blank screen I call "Blank Screen Mode". This mode is recognized by adb commands but not by RSD Lite. Any time an adb command is used apart from rebooting, command prompt says <waiting for device> and the device does not respond.
2.) Motorola Splash Screen Only: This mode is only accessible by connecting the phone to a wall outlet. This mode does not charge the phone and if the phone does not have any power otherwise, will power down without warning upon being disconnected from the power source.
3.) Boot Mode Selection Menu: This mode provides various options that appear to do nothing. The "Recovery" option that is supposed to bring me to the default android recovery mode instead brings me to the Motorola Boot Logo and then to a green android laying down with a red triangle over it (with an exclamation point). I am able to access AP Fastboot Flash Mode from here.
4.) AP Fastboot Flash Mode: In this mode, the device is recognized by the computer as an adb fastboot device (not as an XT894 device). It does not respond to adb commands, and the adb terminal does not acknowledge the phone in this mode. RSD Lite does acknowledge the phone in this mode, but trying to begin the process to reflash the stock firmware causes the "Low Battery/ No Program" text on the phone to flicker and result in a failure in the RSD Lite program. It lists the reason as: Phone return(ed) Fail.
5.) Computer Charging Mode: When connected to a computer, and immidiately powered off, a green LED light turns on. After leaving the phone for some time, the phone can be disconnected and stands on it's own power without needing to be connected to a power source to remain on. In this mode, the screen is not on, and the phone is not recognized by the computer at all.
Methods I Have Attempted to Use to Charge Phone
1.) Plugging Moto Stock USB charging cable to computer and leaving it: This causes the 1st mode listed above to occur, and no charge is held. After 10 minutes of "charging" upon disconnecting cable, phone shuts off abruptly, and without any warning.
2.) Plugging Moto Stock USB into USB to Wall Outlet Plug: This causes 2nd Mode listed with similar results to above.
3.) Plugging Motorola Wall Outlet Charging Cable to Phone: See above
4.) ALL Above Methods + Boot Mode Selection Menu BD Tools Mode: I read that if you were to connect your phone to a wall outlet after booting it up into the Boot Mode Selection Menu, and selecting BD Tools, the phone would boot up to the Motorola Boot Logo screen, then show a battery charging similarly to how one does if you charge your phone after it shuts down from having 0% Battery. This was not the result I received. Similar results to #1
I apologize if there is some blatant simple answer here, but I have looked everywhere to find a solution to no avail. I included everything that occured between then and now so as to facilitate this process, and hope that I am not stepping on any toes with the wall of text I just posted.
Thanks in advance, if more info is needed (or if the post needs to be formatted in an easier to read way) just say so.
Sounds like you will need a motorola factory cable. I think that's what they are called. It provides power directly to the phone allowing you to fastboot. I know you can find them on ebay. I believe team black hat also sells an adapter to turn your regular OEM cable into a factory cable.
Your other alternative would be to sacrafice a usb cable and attach to the battery terminals directly to charge the battery. If you google it you should be able to find directions for how to do this. I believe someone posted a how to on youtube for the razr which should give you a good idea of what you would be getting into.
Good luck!

Fixed It
Thanks for the help.
I didn't feel like paying $12 dollars and waiting several days to purchase one of those special factory cables, so I ended up taking a non-USB charger, spicing it, and hooking it directly to the battery terminals like you said. After I did that, it automatically said that it was "OK to Program".
The only problem I had was that RSD Lite wasn't able to fix it, I had to download some other app that ran things through command prompt while the device was in AP Fastboot mode. But the end result was the same.
I found out that the problem that caused all this was me not flashing the CyanogenMod firmware into ROM Slot-1 while in the safestrap recovery mode. I flashed it to the "Stock" ROM Slot instead.
Thanks again for the help, I learned a lot, and I am glad I didn't have to shell out money for a new phone. :laugh:
I have a Verizon LG G2 VS980. The phone was rooted and running stock firmware.
I hit the "Update software" by mistake on a business trip and when the screen went black, I powered off the device in hopes of preventing the update (which I see now was a HUGE mistake.) Now, the phone only boots into fastboot mode. When I try to hold the vol + and power, it takes me straight into fastboot as well as the vol - and power.
I have tried to do the factory reset by holding vol - and power and then pressing it again when the LG splash screen shows. When I select to hard reset the phone, it goes into fastboot mode.
Now, when I plug the device into the computer, the computer will not recognize it. I am using the manufacturer's data cable, I have tried multiple USB ports, I have uninstalled and reinstalled the drivers countless times. Neither fastboot or ADB in command prompt recognize the device. However, the device does show that there is an android device plugged into the computer.
I have spent hours looking through every thread that addresses issues similar to this but I have not found a solution yet. What can I do from here?
First of all this belongs in Q&A not development.
Are you doing the hard key combo correctly? Power the phone down, when when it reboots is vibrates. When it vibrates you hold power and volume down. At the splash screen, you release it then hold them again.
Did you try this thread?

When you held power up and volume on reboot, did you have it connected to the PC to see if you had download mode?

-check your device manager and see if your computer recognizes it.
-Try another computer.
-Another USB cable
Your computer should recognize it since you had it recognize it before.
Yes, I have tried multiple usb cables and have tried to get into download mode both plugged into the pc and unplugged.
Am I correct in assuming that step one needs to be to find out how to get the computer to recognize the device?

Hi all,
I rooted my phone and unclocked bootloader.
My rom is a stock rom.
I managed to install CWM recovery using lg-optimus-4xhd-recovery-v1.0.apk but something happened.
I rebooted my phone in recovery mode and it is always locked to LG logo.
Pressing Volume up and power I can see normal android system recovery, wiping cache and factory reset don't work.
I haven't usb debugging enable so my computer can't see the phone connected with usb cable, and it's impossible for me flashing the phone with kdz rom methods.
What can I do?
Thx in advance for your answers
No one can help me?
Flashing with kdz results in "phone was not found", is there a way to resolve? I've tried with ubuntu, OS (adb) only see my phone if usb debugging is enabled and it isn't, and with a laptop running win8, installing LG drivers and so on, nothing works.
This is salvagable
If you can get the stock recovery mode, all is not lost, all of the important bits are still functioning.
Power down. Hold VolDn and insert the USB cable. If you get the Software Update screen with a green icon you CAN recover the phone. It may require a battle with Windows to get it to play nice, Windows and USB is always a hit or miss affair; but the phone is ok if that screen appears. Do not use the VolUP + Power LG Recovery mode, there isn't a known tool for that in the wild.
I don't normally run Windows and the couple of times I have booted it to do this it required some hassle and usually skipping the nice way since I had never installed the bundled LG Desktop stuff before things went wrong. So just do what I did, pick the Emergency mode that requires inputting the IMEI instead of letting it detect your phone and then let it fix things for you.

Many thanks for your answer, I resolved the problem late at night, yes, after a hard battle with windows.
I installed windows 7 32 bit, I tried a lot of Lg drivers, 3.8.1 maybe the best, after inserting the USB cable with SW Update screen some LG peripherals were recognized but the result in KDZ_FW_UPD was always "phone was not found", then I tried connecting USB cable with the Phone in Android recovery mode ( power & Vol up), and OS added a couple more peripherals, and attempting again with SW Upgrade mode worked.
Hello everyone,
It seems that my worst nightmares came up, and got my device bricked while trying to flash it to a stock ROM (had a custom multilingual ROM installed by the chinese seller), and now it's in a strange stage, as Windows detects the Qualcomm port, but adb can't see it.
The adb devices list is in blank, and QPST detects everything, but when trying to flash the device, the error message on the screenshot appears.
Also tried to do it with MiFlash, but didn't worked too.
Any idea about how to solve this?
Thank you in advance for your help.
P.D.: My device is in black screen, so no menu or anything.
P.D.2: Already downloaded the Android SDK in order to try it's ADB, but it didn't worked too.
Now after some research, I found out that the "ADB interface" is not showing in Windows device manager
I tried to install it manually, but can't find a way to get it working, and after the flash, USB debugging was set on, so can't figure out what could be happening...
Is it possible it's completely dead?
Any idea?
Just to say that I have tried multiple combinations while plugging the device to the PC, and didn't worked...
I mean, the PC seems to react, but always with the same end, only shows the Qualcomm port 9008, nothing about the adb...
Getting out of ideas, anyone more has some?
did you start the tool with admin rights?

Yeah, I already started the cmd with admin rights, but the problem is that adb does not works, as the device is not turning on.
As you can check in my first post, in the screenshot, after running the "adb devices" command, it doesn't gives any kind of error, just returns a blank list.

adb will never recognized it, in 9008 mode or it's called EDL, the only program that recognized the port is QFIL / Miflash. if you get an error when flashing you must reset your phone again to repeat the process by pressing power button for a couple seconds. if your bootloader already unlocked that must be simpler to do, just press power button for a couple minutes until shor vibration then press vol up + vol down and connect to usb at the same time..

Thanks for the info, I've tried the vol + and vol- buttons after the short vibration, and the PC does not detect the device...
Is it there any other way to get the device detected by the PC?
Actually, the only thing the device does, is the following:
After pressing the PWR button for around 5-7 seconds, it makes a short vibration and the notifications led makes a flash in green colour, but nothing more... If you keep pressing it, around 7-8 later, it makes a litte bigger vibration and a flash on green too... And if you continue, it does on, and on, and on...
Any idea? Anyone told me about getting a Xiaomi Deep flash cable, but I'm not sure about if that will work or not...

i've already tried xiaomi deep flash cable, and its work on my z2 plus, that's how to force phone into 9008 mode.. and also, dont add space between folder names where your firmware files there or there will always sahara fail
Hey man!
I had the same Problem!
Sahara error, no reaction from device, black screen, port recognized in qfil etc.
I found out that this behaviour of the device means, that it is in EDL-mode.
what helped ma was:
1) Unplug everything.
2) Set up the QFIL Tool completely, but do not hit "Download Content".
3) Try to "reboot" the Zuk Z2 Pro by pressing the power button for several seconds. Kind of resets everything.
4) Plug in USB
5) execute: "adb reboot edl" via adb
6) unplug USB
7) plug in USB and immediately (within a second!) hit the "Download Content" buton, just after it is clickable.
8) dowload should start without sahara error
Hope it works! :good:
Well, finally, I talked with the aftersales dpt from the shop where I got the device, and returned it, and incredibly it seems it was defective.
The guy from the tech dpt said that it wasn't supposed to die that way, so they returned me a brand new device, and fortunately it's up to date with ZUK's last official ROM.
Thank you everyone for your ideas and help, now I can enjoy this great device
My Zuk Z2 plus got stuck after TWRP, I need help badly.

I will tell my issue
I bought this device this July month, I was encouraged seeing you guys did a lot of flashing, I thought I could flash myself but it became a nightmare now.
I am not that much technical so please bare my usage of words below, but I need a real help.
I was doing the basic TWRP for getting the AICP ROM 12.1 but after wiping the data from TWRP my device doesnt get recognized for the Sideload and I did whatever I can but it doesnt detect my phone, so I am having a screen with Start "Green" which is showing the device status as unlocked and when I click on Recovery it goes to the Zuk logo and doesn't have any sign after that.. stuck really
I tried using QFIL but my device detects as 900H but not 9008 also adb doesn't detect my device at all after this.
I think I really did a hard brick of my device.
I dont want to loose hope, I want your help really badly.
For those of you who had the same problem don't give up! I was in that same situation and I solved by putting my phone on EDL via this method
https://www.youtube.com/watch?v=2m44xKog-dI
After plugging the phone for the second time and QFIL recognize as EDL mode I clicked on download content as fast as I could so it started to flash the ROM that I spent like 10h trying to figure a way to do it lol. Anyways, the procedure is the same as putting into EDL via adb fastboot, the only difference is that you make it through a "fake" deep flash cable as that guy in the video shows.
