SDK platform tools command window not recognizing device - Nexus 6P Q&A, Help & Troubleshooting

I tried the instructions in this video (https://www.youtube.com/watch?v=NGy85rFFhLM) to try and help me install drivers because my bootloader wasnt being detected by fastboot, but at the part where he connects the phone and opens command prompt to type adb devices all i get back is this : http://imgur.com/3Y1N2gr I've been stuck at this step for over a day now, I've tried 4 different places for help not much luck anywhere :/

Read the whole thing 2-3 times. Understand it. Then do it.

Problems with Fastboot

I can't get fastboot to work. I never have really tried it before, so maybe I'm just doing it wrong, but when I turn the phone on using the camera + power method, I get the Androids with skateboards, press back to enter fastboot mode. When I connect the usb cable, it shows "fastboot usb" for one second on the phone, then goes back to "fastboot". I try to connect using the comand prompt all I get is "waiting for device"
Here is what I'm running
Dream PVT 32B ENG S-OFF
HBOOT-1.33.2005 (DREA10000)
CPLD-4
RADIO-2.22.19.26I
ROM: Dudes 1.2
Aero Theme
I do have the USB drivers for both bootloader and ADB with the fastboot.exe file with the SDK/tools folder.
I am running Windows XP professional.
I thought it might be the new SPL from haykuro, so I flashed back to the old Hard SPL with no luck. I have uninstalled the fastbood & ADB drivers, then re-installed them and it still doesn't work.
I searched the forum also & found some people with similar issues, but none of their fixes worked for me.
If somebody could give me a check list of things to check, I would appreciate it.
Thanks in advance.
did you try re-installing the drivers after you plugged in the USB it fastboot? i had a problem similar to this a long time ago, and the drivers were only loading in normal mode when android was booted up for adb and all that good sh*t. i booted into fastboot, plugged in the usb cable, and installed the drivers while at the fastboot screen. hope this helps any
I think I have. I kind of remember uninstalling the drivers, restarting my computer, plugging it in (while in fastboot) and installing the drivers when the "found new hardware" screen popped up. Guess I will try it again and report back.
Thanks.
I fixed it...
Okay, I figured out what I was doing wrong.
I checked the usb driver, found that while installed, it was not enabled. I went ahead and re-installed it from the android sdk just to be sure. Afterwards I found that when I was in fastboot mode, it would say "fastboot usb" instead of just "fastboot".
I still couldn't get use fastboot on my computer and see the device attached.
Turns out I am also an idiot. What I was trying to do is flash a new boot screen. I was reading this post:

This is updated with the lastest tool. (Windows)
I included a zip with all files you may need at the bottom of the post.
1. Turn off your phone
2. Turn on the phone into bootloader (camera+power).
Make sure it say fastboot in the middle if not hit back and it should appear-
3. Make sure your device is found in device manger
If you don't see adb device up top in device manger find the yellow mark devices
Right Click, update driver, and point to the location of the USB Driver
(http://dl.google.com/android/android_usb_windows.zip)
4. Open and extract the below zip to your desktop
You should now have a custom and fastboot folder on your desktop
5. Open up a dos window (start>run>CMD)
6. Type cd desktop then cd fastboot
7. If you would not like to flash the sample images skip to step 9
8. copy and paste the command line by line
fastboot flash splash1 mysplash.rgb565
fastboot flash splash2 mysplash.rgb565
fastboot reboot
Part 2 Making your own images
9. Open up the "create" folder
10. Run CreateG1Splash.exe
11. Open up your image in the program and click convert
12. Goto the folder of your images and their you will find mysplash.rgb565
13. Place the mysplash.rgb565 into the fastboot folder
14. copy and paste the command line by line
fastboot flash splash1 mysplash.rgb565
fastboot flash splash2 mysplash.rgb565
fastboot reboot

trying to do it. I was following the post trying to run fastboot from the desktop directory (which the folder was there). However when I tried running it from the SDK/tools folder on the root of my C: drive everything worked great. I have a new boot screen and everything was easy after I figured out to do it all from the /tools folder.
Even though I didn't get a lot of support with this problem I posted, I would still like to thank everybody here at XDA. I try to keep my questions down to a minimum and search the forum, among other places, before I ask the help of everybody here.
Thanks again.
NICE!!! I tried a whole bunch of solutions as well. Finally, I stumbled on yours, and it worked! Hell yeah! I think maybe adding fastboot folder to the path of system variables may have done the trick, too.
Thanks!!!

best advice i got was load up your phone is fastboot connected to pc...run the same commands in cmd but go through SDK/Tools and run fastboot from there once your in tools...skip putting it to your desktop...that didn't work for me
Hey guys, I have a problem, the driver is installed, but I can't see the device when I go to the cmd. I need help please!
Also, since my recovery is dead, and my cyanogen rom is dead, I have no way to revive my phone... can anybody help me please?
99.9% of the problems with getting fastboot to work are actually problems with windoze and incorrect_drivers/driver_conflicts/windoze_is_retarded.
Best thing to do is use Linux. No special drivers needed.
And this is not to start a linux is better than windoze fight (even if it *is* better )... it is simply a matter of this; android *is* linux, it was developed with linux, that's what all the platform developers use, and simply put, it is absolutely and fully compatible, so when all else fails, that is what you should use as well.
Option a) grab latest fedora livecd and boot off that,
Option b) grab latest fedora installdvd and install it to something and boot it up,
Then:
copy the fastboot executable into any directory (download from developer.htc.com),
connect USB,
put phone in fastboot mode,
./fastboot flash {partition} {image}
And it'll "just work".
Note: http://www.fedoraproject.org/en/get-fedora
omg. countless hours spent on trying to do this. and all i had to do was to use the fastboot in the sdk? thanks youuuuuuuuuuuuuuuuuuuu!

Solved having trouble getting root

I am running Windows 7 x64 I have no idea if following this guide on another operating system will work, this is just a step by step of EXACTLY how I did this, Not to say this is the only way. I have tested other methods and I have put in different variables and I have successfully gotten it to work several times in a row doing it this way while following jp4756's guide. I am sure this is not the only way to accomplish root, however this worked for me perfectly. PLEASE don't skimp out on any step. There is no shortcut here just follow the steps and jp4756's guide to the TEE!!!
Step 1.
Uninstall pdanet/htc sync/ any other thing you installed to get all this to work before
Unplug phone from computer usb cables and have phone powered on and in settings menu
Step 2.
download USBDeview(install it) easy to google it
download HTC SYNC(do NOT install it yet) for mytouch slide easy to google it
Step 3.
While in settings menu go to Application
go to Development
and check the box USB debugging
Step 4.
In settings go to Connect to PC
touch Default connection type and choose Sync
At this point you have the phone not plugged in, you have the setting on the phone changed, you have dowloaded usbdeview and installed it, and have htc sync dowloaded
Step 5.
Start USBDeview(some may have to right click the exe and run as administrator) and delete all android drivers and mytouch drivers, anything relating to android
Install HTC SYNC and let it completely install
Step 6.
Plug phone into computer and let the computer auto install drivers etc...
Step 7.
turn the phone off. Power on the Slide into the bootloader by Holding Down ( Volume Down + Power Button ) After it does its little thing your computer will beep and start auto installing drivers and stuff
Step 8.
If everything has gone according to plan in Device Manager it will show Android 1.0 or w/e with a exclamation point. Right click on that and choose Update Driver Software
2 options pop up choose Browse my Computer
then choose Let me Pick from list...
a list will appear giving lots of choices
choose Android Phone should be the first choice that says android....
then 3 options will appear, choose the 3rd one that has Composite in it and choose okay.
Step 9.
Now select Recovery from the bootloader menu
after it is done doing its thing completely 2 things will happen
1) In device manager you will now have something under disk drives
2) USBDeview a new driver will pop up at the end of the list, something like this:
Port_#0004.Hub_#0004 T-Mobile myTouch 3G Slide USB Device Mass Storage Yes No No No E: HT05RPS05696 6/16/2010 4:00:58 PM 6/16/2010 4:07:35 PM 0bb4 0ff9 08 06 50 USBSTOR USB Mass Storage Driver USBSTOR.SYS USB @usbstor.inf,%generic.mfg%;Compatible USB storage device
Step 10.
This new driver to appear shows Yes under the Connection column. This needs to be disabled. Right click on it and choose Disable Selected Device
after about 10 seconds it should no longer say Yes under connection column, if this does not happen then you are not running it under Admin.
Okay so now you are literally almost freaking there.
Step 11.
Now basically all you have to do is follow jp4756's guide starting with step 5. Im going to assume you already understand steps 1-4 in his guide. And you already have the package listed in his guide as well. You have already put those files where they belong
Step 12.
Okay so we are basically following his guide now. first things first
5. run the update.zip it will fail(MUST DO)
6. now in cmd type adb reboot recovery (don’t press enter)
7. in the recovery hit reboot system now( once it starts rebooting run that command rapidly untill back into recovery) <--- Basically while the phone is rebooting you are just hitting up arrow enter up arrow enter up arrow enter up arrow enter in CMD. You will know when you can stop when the CMD freezes for a sex, computer makes beeping noises and the phone reboots basically. It is headed for recovery and we must switch our command now
8.type adb devices(if it says nothing repeat the steps, if it says offline unplug it and then plug it back in, if it says recovery your fine) <---- Basically after you know its headed for recovery you change command to adb devices and you repeat previous procedure, up arrow enter up arrow enter up arrow enter etc.... I did not use loop, i did this all manually.
This may take a few tries, if it does not show offline then go back to step 6 rinse and repeat. You go back and forth just a few times and you will have it. Literally within about 3 tries you should accomplish the annoying goal of having offline stay there.
My job is done, follow guide and continue on your quest for root
There is no guarantee this will work for everyone. I am not claiming that this is 100% Im just giving an explanation as to how i got it and what might have been causing everyones trouble. Results may vary
Thank you to all the devs who made this possible and jp4756 for his wonderful guide
Wow that is just way to much stuff there...
I've ran loop on 2 totally different Computers running 2 totally different OS's and running 2 totally different Drivers, I have no problems with either one..
1st: XP sp3 32bit w/ PDANet Drivers <--- Only ones that I could get to load, Forcing drivers wouldn't work in XP... also like I said before, make sure to close the PDANet Program in the Toolbar.. Also make sure to read the directions when installing PDANet...
2nd: Windows 7 64bit w/ Htc Drivers <---PDANet Drivers also work... You have to force the HTC Drivers in Devices Manager..
I think most people are having this problem because they aren't doing the USB Debug thing. But could be Wrong.
Also a side note my phone is running the USB Drive and not SYNC works just fine...
Also It just might be your computer so I would try and use a different one if you can.

Sorry that we all can't be as cool as you jnight666, but some of us are having real problems with no apparent explanation. I am an IT professional with access to every kind of computer used in the modern world, and trust me, I've tried all the ones that apply. Rubbing it in our faces that it was just so easy for you is just rude.
THE DRIVER MAKES NO DIFFERENCE FOLKS. IF YOU CHANGES DRIVERS AND THEN IT WORKED, IT'S PURELY A COINCIDENCE. PEOPLE HAVE GOTTEN THIS TO WORK ON MANY DIFFERENT DRIVERS.
THE CONNECT TO PC SETTING ON THE PHONE DOES NOT MAKE A DIFFERENCE IN FASTBOOT/RECOVRY FOLKS. IF YOU CHANGED THIS SETTING AND IT WORKED, IT'S PURELY A COINCIDENCE. PEOPLE HAVE GOTTEN THIS TO WORK ON VARIOUS DIFFERENT SETTINGS.
That being said, this didn't solve mine. I still cannot root.
And Yes, my cap locks was on purpose.
Okay, please dont come in here and start telling me how my method is wrong. I already stated there are other ways to accomplish it. I had already stated that this isnt 100%. I am merely offering an exact procedure that i duplicated SEVERAL times, with it working for me every time. If this isnt how you accomplished it then pls, theres no reason for you to be in this thread posting negative comments.
With that said fermunky, did you follow the procedure to the tee? - btw im not assuming anything so please dont take it personal. Im just trying to help ppl : )
My caps wasn't to be negative. There are too many people claiming the drivers were a key. And I am not saying yours said this, but it also doesn't clearly say it doesn't. That is all.
Completely understandable, and definitely no disrespect to you or anyone here
When I disable the Mass Storage I see other items in USBDeview that reference the Slide. I end up in a loop after rebooting and rapidly entering adb reboot recovery. I was seeing everything as your instructions explained.
Do you think it is worth a shot to disable all but one item for the Slide? Any suggestions would be greatly appreciated. I work in an IT Escalation Group and this has to be one of the toughest nuts I have tried to crack! LOL
Thanks,

3 different computers 3 different op systems installed uninstalled drivers different programs etc...some phones are hard to root its a ambiguous situation
Yeah sorry I wasn't trying to be rude.
I was just trying to be helpful, sorry if it came out that way...
I also have the loop not working issue but i usually only happens once or twice..
I feel your pain I had trouble with the push Update.zip part of this thing and I was trying it for hours...
I was just trying to tell you what worked for me...
If you tried different computer and still no luck then im guessing its the Phone that is the issue or the USB Cable...

You definitely don't want to do that, as one of them is one that you need to be connected once you finally get to see offline stay. Are you rebooting using the method described in jp4756's guide? meaning your rebooting using the recovery option reboot, then in command doing the adb reboot recovery, then once you no the phone is gonna boot into recovery you switch to spamming adb devices? When you say your in a loop it sounds to me maybe your not doing the adb devices after the phone listened to your adb reboot recovery command
Followed your instructions...
No ! next to anything in device manager. Right clicked on Android Phone > Android ADB Device and went to properties to update the driver. Nothing in the HTC folder would work, they both said that they weren't applicable for the device...(this was in C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64)
before plugging your phone into your computer a single time, can you confirm that you started up USBDeview and uninstalled every single driver related to android, or mytouch or htc etc... Also before ever plugging your phone in a single time did you install htc completely?

after getting some sleep and starting fresh, i tried this method again this morning. on the fourth or fifth try i got my slide to stick in offline mode. so then i unplugged it and plugged it back in to get into recovery. lost it, and now im on my 50th or so try to get it back to offline mode.
i need a stiff drink lol
it seems partially a driver issue and also an adb issue i thinks. it connects 'when it feels like it'
i'll report back if i make any progress.
btw im doing this on XP Pro SP3 fully updated
edit: I also noticed when adb does catch the slide, 2 instances of adb are running, then one closes and loses the phone. maybe this will help solve some of the problems
You've misunderstood that post. Only one instance of ADB will show when the loop is not running. Once you start the loop, another instance of ADB will show up and disappear many times. This is normal. As long as only one instance is showing before loop, you are fine.

I would just like to say that I have followed every method listed in these forums, achieved root the first try (using the updated update.zip). My problem occured when flashing the eng rom, I lost clockwork,root and now the phone runs like sh!t. Yes, superuser was installed and yes my pc no longer recognizes the phone when searching for adb devices after pushing the first 2 files from the eng flash walkthrough.

maybe your downloads were corrupted. that's really strange...
man, that really sucks! I am truely sorry...
after spending 20 hours or so on rooting, I really feel your pain.
After I reboot into recovery mode and then use adb to check for my device I never get it to show up. Just so I am clear when you say 'spamming your device' you mean after reboot and rapidly entering the reboot recovery command, then looking for device with adb devices command. I never get it to show.
Thanks for the reply!
No devices in adb?
So I had this same problem with my MT3G. Type in "adb devices" kills the last device and it lists connected devices and NONE were listed. Not sure exactly what I did, but did eventually get it working. (I was trying to use the emulator)
Now though I'm having the same problem with my wife's MTS. Any ideas?

[GUIDE] [UNBRICK] Unbrick Oneplus One

*** I've been receiving many requests and PMs from members asking to help them unbrick their device. Please note that I no longer own this device (and even if I did I would not purposely brick it just to reproduce your problem), therefore I am unable to help out beyond this tutorial. ***
Hello,
First some background and credits:
There are a few ways to brick a phone. Sometimes it's lack of experience, sometimes it's an accidental thing, sometimes there just isn't an explanation for what went wrong... (share your experience here, if you wish). For me, I owned my OPO for about 4 hours before things went wrong. First thing I did was I rooted it and installed TWRP. After creating a nandroid backup of the stock image I installed my favorite custom ROM and restored all my apps with TiBu. Everything was great and configured just the way I wanted it. I then wiped my old phone (Nexus 4), installed a new ROM and got it all ready for my wife. She was so excited to get rid of her GNex and move up to the N4. But then, for whatever reason, I opened an app on my OPO that I used to manage, download, and install kernels with. It came up with "there is a new kernel update!" and I instinctively clicked on "Install". 10 seconds later my phone was bricked. Nothing came on the screen, no fastboot, no recovery, nothing to boot to, no way to send data to and from it. The second the screen went black and the phone became lifeless I got that wretched feeling in my gut as I realized I just flashed a N4 kernel on my new OPO. Restoring the kernel management app with TiBu made it act like it's still running on my old phone, and in my excitement I didn't take a second to think things through...
I received a bit of consolation when a quick XDA search revealed that I am not the only dumbass to brick his phone this very way. I joined forces with some pretty smart and desperate people and tried different things, all described in the following thread: http://forum.xda-developers.com/oneplus-one/help/wrong-kernel-black-screen-fastboot-adb-t2835696. Unfortunately it took us what seemed like many long weeks to figure it all out. Well, in the end a solution was found and I documented it in the the following post: http://forum.xda-developers.com/showpost.php?p=55024864&postcount=136.
This was a few months ago, but I recently noticed many people continue to search for these directions and have problems finding them hidden among many pages and other threads, so I've decided to put this stand alone thread with these, now updated, directions.
Let me get one more thing straight, for the record. I did not find the way to unbrick the OPO. In fact I wasn't even the very first one to do it. It was a collective effort of few people who tried many different approaches and ideas, and I eventually documented these steps for others to follow. Being said, the following people deserve credit as well: @os_man, @rezor92, @Mnt-XDA. If I am forgetting other significant names and efforts, I apologize.
***CAUTION***
The following instructions are for hardware bricked devices ONLY and will not work on soft bricked devices. To determine whether your device is soft or hard bricked, click the button below:
Hardware brick
A hardware bricked OPO has nothing but a black screen (nothing ever comes on the screen, not even a boot logo), it might vibrate when a power button is pressed and held for 20 seconds, has no Recovery partition, no adb mode, and no fastboot partition. The device might be detected in Linux and you might be able to even send commands to it. In Windows, the bricked OPO should be detected as QHSUSB_BULK USB. You might have a bricked OPO as a result of flashing a kernel meant for a different device (or a ROM meant for another device that included a kernel), tinkering with the boot logo or bootloader, or your attempt of unlocking the bootloader resulted in corrupting the boot partition.
Software brick
Please do not attempt to use these directions if your phone is soft bricked. A software bricked OPO is one that might be stuck in a bootloop, but has a working bootloader, recovery partition, fastboot, or adb. If you press the power button and images appear on the screen and you are able to enter fastboot mode (Power + VolUP) or recovery (Power + VolDOWN) then your device is soft bricked. This thread does not encompass soft brick recovery, the instructions below do not apply and will not work on these phones. Consult other threads for help on soft bricked devices.
If based on the above explanation of differences between soft and hard bricks you determined your device is hard bricked, here's what you will need to do...
1:
Download Color.zip from (mirror needed).
After downloading, unzip the archive on your computer.
2:
Next, you need proper Windows drivers. There are architectural differences between Windows XP and Windows 7/8, so follow the directions below that pertain to you. One quick note about the drivers: the installation and process is very simple and straightforward on Windows XP (I also tested successfully on Windows 2003), but proves to be quite a challenge when running on Windows 7 or 8. Over and over people report issues when attempting the unbrick procedure on Windows 7/8, some have more luck than others. Being said, if you have access to a Windows XP computer, I highly recommend that you use that. If you have no choice but to use a Windows 7 or 8 computer and have problems, please share them here and read others' experiences.
So first, by now you probably tried a few different things to fix your phone and you've already installed some drivers, including Qualcomm USB drivers for 9006 and 9008. My best advice is to uninstall the drivers you tried so far and use the ones listed below. Go to Device Manager, right click on the bricked USB device (QHSUSB_BULK or Qualcomm HS-USB QDLoader 9008) and go to Properties, click on Driver, then select Uninstall. Check the box to remove driver files, if prompted. Then:
2a:
Windows XP users:
You are in luck, driver installation is straightforward. Go to the extracted Color.zip folder and find Driver.iso. Extract Driver.iso. Inside the extracted folder find Setup.exe. Run Setup.exe to install the drivers. The installer is Chinese, but all you need to do is click through the prompts.
2b:
Windows 7 and Windows 8:
These operating systems block unsigned driver installations by default. Follow these steps (thanks @nag4pl for testing these):
Download and extract these Qualcomm 2012 drivers: (mirror needed).
Connect your bricked phone and let Windows do its thing.
Now something very essential you need to do here is to execute two commands to allow you to install unsigned drivers for QHUSB_BULK. Click on Start Menu > Type cmd.exe > Right Click and Run as Administrator.
In the CMD window type in the following commands (hit enter after each):
Code:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
Code:
bcdedit.exe -set TESTSIGNING ON
After both the commands should run successfully, restart your computer.
You can now proceed to install unsigned drivers from the file you downloaded. Open Device Manager, you should be seeing ugly yellow warning under other devices for QHUSB_BULK. Right click on the name and select Update Driver Software > Browse my Computer for driver software. For driver software location provide the path where you have extracted Qualcomm 2012 drivers you downloaded and make sure 'Include Subfolders' is checked. Proceed through all the installation prompts ignoring any warnings.
3:
Once you have the drivers straightened out, connect your bricked phone to the computer and start it up by holding VolUp + Power to about 10 seconds, and let the computer do its thing. Don't install drivers if they are not installed by itself. Instead launch Msm8974DownloadTool.exe as Administrator (right click on Msm8974DownloadTool.exe and select "Run as administrator") from the extracted Color.zip archive. It will scan all the COM ports and find the phone. That's the one line that looks different in the list. The list is just a list of your com ports and devices. If you unplug the phone and move it to another port, it will show your bricked phone on a different line.
Clicking on "Enum" just rescans the busses. Clicking the big square button in upper right corner scans the phone and reports what's good and what's not. It takes a minute for the scan to finish.
If you don't see your phone in the list of com devices, try unplugging/plugging in your phone a couple times, and rebooting it with VolUP + Power (hold 10 seconds). You will see it in Device Manager as well.
Once you see the phone in the list, click Start. You should see the programs start writing different files to the phone. Each time it writes a file you'll see a progress bar. Once you see this process happening, smile, you know you will be good to go... After all files are written, the com line with your device will turn green. You're good, unplug and reboot your phone. It will boot to ColorOS, the Chinese OS that comes on OPO.

Optional Steps:
Your phone is no longer bricked. You now have a few options to get back to stock. The easiest way is to use a toolkit from http://forum.xda-developers.com/oneplus-one/development/oneplus-one-toolkit-manudroid19-gui-t2807418, or you can flash an image manually by following directions from: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541. Download the proper image zip and after extracting it, run the following commands in fastboot mode:
Code:
fastboot flash boot boot.img
fastboot flash userdata userdata.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash LOGO logo.bin
Make sure you have the proper image. I accidentally installed the 16GB version on my 64GB OPO first time and obviously didn't get 64GB of space.
That's about it. I think if people are still having problems then it's likely due to drivers, or Windows 7/8 issue.
Good luck! Share your experience here and let me know if I can improve this thread.

You should be able to boot to fastboot now. From there flash the cm11s image. I believe that "fastboot flash sbl1 sbl1.mbn" will fix the imei issue.
Also, unlocking bootloader does not void your warranty. Not with OPO.

Just to give one last try, flash color os modded zip from relic, i used 2.0.43 purezip and it gave me back my imei. Had the same issue as you last week. Be sure to flash TWRP 2.8.4.1 first and then flash color os.
Legit method.
Worked for me 2 weeks ago!
unbrick oneplus one, oppo 7
Hi there my friend, i had many works about unbricking solutions, a few of you know that, i have much easier and faster ways now, tested many times before i decided to share with you, it will be a long topic ( and my brain is messed up to sum them up clearly), as soon i can think clearly again, i start to write them, till then,
greetings from Istanbul to all geeks around thw world.
Ps: including restoring imei's if they got lost during this process.
Ps2: just a quick info abou imei, if your imei is "invalid" , this means your modem.bin (NON-HLOS.bin, baseband) is not inadaptable with your rom, just try flashing the right modem ( from fastboot), your imei will be back.
Ps3 : This will lead us to unbrick many Snapdragon's out there , not only oneplus one's or oppo's.
I had to use this tutorial some days ago.
There is also a modified .zip where the tool from OPO flashed CM11s instead of ColorOS.
http://forum.xda-developers.com/oneplus-one/general/tool-oneplusrecovery-tool-v1-0-restore-t2991851
I had many driver problems and i had to use this driver from qualcomm so my win7 could recognize the phone.
Tutorial to install the driver:
1. Open your device manager (Start - right click on computer - properties - devices manager)
2. Press on power + vol up for like 10 sec until you see a device showing up (called QHSUSB_BULK)
3. Right click on this devices and click on "Update Driver Software" -> "Browse my computer for driver software" -> locate the Qualcomm 2012\fre\Windows7 8 or vista folder depending on your setup. Update the driver.

Thank you.. Troubleshooting my phone now..

Back from Brick!!
First of all Thanks a lot to @netbuzz(for such a life saver guide on unbricking 1+1) and @michaeldepotter for providing link to download appropriate drivers.
Here is some good news by my findings and can be a quick help for those who do not have or can't get XP. You can use Windows 7 itself for the process mentioned by @netbuzz
All you need to do is:
1. Download drivers from link provided by @michaeldepotter : https://www.dropbox.com/s/vgujdut93m341qm/Qualcomm 2012.rar?dl=0
2. Extract to some folder under C: or whichever drive you prefer.
3. Connect your bricked phone after pressing Volume Up and Power key (make sure phone vibrates once)
4. Now that QHUSB_BULK should be detected and Windows will eventually try to download drivers from update, which you can skip and close the window.
Now something very essential you need to do here is to execute some commands so that you will be able to install unsigned drivers for QHUSB_BULK.
4a. Click On Start Menu > Type cmd.exe > Right Click and Run as Administrator (make sure you are running cmd as admin)
4b. Now type below command
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
>hit Enter
bcdedit.exe -set TESTSIGNING ON
> hit Enter again
4c. Both the commands should run successfully, then restart your computer.
These steps are to disable driver sign verification. You must proceed to next steps only after above steps executed successfully.
After machine booted back to desktop
5. Now Open Device Manager by Start > Run > type "devmgmt.msc" and hit enter
6. You should be seeing ugly yellow warning under other devices for QHUSB_BULK.
7. Right click on the same > Update Driver Software > Browse my Computer for driver software
8. Now under driver software location, provide the path where you have extracted drivers which you downloaded from step 1. For me it was:
"C:\Users\Arjun\Downloads\Qualcomm 2012\fre\Windows7" - Remember to provide path only till windows 7 and make sure 'Include Subfolders' is checked.
9. Click next, and it should install driver for QHUSB_BULK. Click on Install Driver if you get any warnings.
Now your driver set-up for QHUSB_BULK in Windows 7 is complete and now you may proceed with the steps to run Msm8974DownloadTool as provided by netbuzz.
I have attached the screenshots for the same just for confirmation.
SuccessfullDriver - showing successful installation of driver
FlashInProgress - showing tool flashing the system image
FlashSuccess - showing green row indicating successful flash.
Once again, thanks a lot for all the guide and help. Hope this quick guide helps some one in need!!

Thanks for this Win7/8 workaround. I'll be adding your info to the OP.
Finally Unbricked mine...Drivers resolved on Win 7
netbuzz said:
Second note about drivers is that I had the worst time trying to get things to work on my Windows 7 computers. Both Windows 7 and 8 block unsigned driver installations by default. I've tried overwriting these settings in Windows and spent half a day messing with it, and I never got things to work properly. At first all looked good to go, but then latter steps were failing. You might have a better luck getting drivers to work on Windows 7 or 8 (I've heard some people did it), but if you have access to a Windows XP or 2003 machine, try it first, it should save you some major headache.
Once you have the drivers straightened out, connect your bricked phone to the computer and start it up by holding VolUp + Power to about 10 seconds, and let the computer do its thing. Don't install drivers if they are not installed by itself. Instead launch Msm8974DownloadTool.exe from the extracted Color.zip archive. It will scan all the COM ports and find the phone. That's the one line that looks different in the list. The list is just a list of your com ports and devices. If you unplug the phone and move it to another port, it will show your bricked phone on a different line.

I have used the override tool for certificates: DSEO - Driver signature enforcement overrider
to allow the unsigned drivers to be used and it worked like charm on windows 7 64 bit.
Also, I used the additional Qualcomm 2012 drivers and not sure which one might got picked in that mess :cyclops::cyclops:
Thanks!!
:good::good::angel::angel:
nevermind!
Well I managed to hardbrick my phone. I am download the ColorOS file from Mega at the moment. It's downloading at 30KB/s and will take around 6.5 hours. Is there any other source to download it from ? Thanks !
Also, about the driver ...
While I wait on the colorOS to download I want to clarify one more thing about the driver.
According to the screenshot of @nag4pl the driver should show as Qualcomm USB diagnostic 9006, while for me it shows as Qualcomm HS-USB QDloader 9008. Is this going to be an issue ?
This is what I did. I uninstalled the default driver that came with windows 7. After that it failed to install the driver provided in this forum because it kept saying that device descriptor failed. I rebooted the phone several times and changed the USB ports and eventually windows detected it but AGAIN with the windows driver even though I had checked the option to delete the original driver while uninstalling it. Through the update driver option I managed to force it to install the unsigned driver.
Now I can see both the drivers under the update drivers option. Interestingly the default driver is a version ahead of the unsigned driver provided in this forum.
My only concern is that I see a different driver name compared to the one posted by @nag4pl
Thanks! Very useful for me!
That shouldn't be a problem. Not sure if that is specific to region, mine is India version phone.. Can some one clarify on this?

Need help unlocking bootloader

I've tried several times to unlock the bootloader and it will not respond to any commands once in fastboot mode. I've tried to follow this guide https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/ but whenever I type "fastboot oem unlock" it just says "waiting for any device" and nothing happens. I have usb debugging enabled and oem unlocking on so I don't know what I'm doing wrong. I have the platform tools from Google installed. I can run adb and type "adb reboot bootloader" and it responds, but after that, no fastboot commands work. I mainly just wanted to root so I could restore my apps and data via Titanium Backup. Is there a temp root solution I can use? Or has anyone else experienced this?
Let me know if you need more info. Hopefully this is an easy one.
What do you get if you run "adb devices"?

I feel like it's something simple I'm missing. I've never had trouble figuring this stuff out. I've been rocking an HTC M8 on VenomRom since forever ago so it was time for an upgrade. I've looked at several different guides, but some of them seem to be incomplete. Like the guide at the official TWRP page says to power off the phone. Then it says to hold volume up to go into fastboot mode. I tried following those instructions to a T, but that didn't actually do anything. It doesn't say where to put the twrp.img file, it just says to run the command to boot the .img. Getting into fastboot isn't a problem. It's that no matter what I do once it's in fastboot, I just get "waiting for any device". I've tried the OnePlus6t Manager because I thought maybe I needed a one-click method. But again, it gets to fastboot and goes nowhere from there.

Do not forget to enable OEM Unlocking in Developer options
Sent from my ONEPLUS A6013 using Tapatalk
Just my 2 cents I'm not an expert but it Might be your drivers or when you installed adb did you do it with administrator rights? The first time tried I couldn't get it to work it wasn't detecting the device in fastboot so I reinstalled adb and then it worked
I just rooted mines today but I went off a YouTube video I looked up and they had everything you needed to download in the description. Took about ten minutes ? I'm not sure if I can put a link on here

I've done that also. Developer options are enabled, USB debugging, and OEM unlocking. Are there newer drivers I need? But if that was an issue, it wouldn't allow me to do "adb reboot bootloader". It'll reboot to fastboot mode, but after typing "fastboot oem unlock" it just says waiting for any device.

This is where I got my version of ADB. https://developer.android.com/studio/releases/platform-tools It's not so much an "install" as it is unpacking a zip archive.

you need to be careful in fastboot. One wrong command can lead to a catastrophe.
I used the adb installer from the same video. Once you unzip it. It's an .exe file which I granted administrator rights to install... it installs adb and drivers and it worked for me
That's the video and did it to a T
Another thing don't use power shell use command

Still getting nowhere. I thought my problem was that I didn't intall the drivers as administrator. So I did it again, following this video https://www.youtube.com/watch?v=B-XZy27wy5o When I reboot into bootloader, I type "fastboot devices" and it just goes right back to the command prompt. Nothing happens. I guess I'm going to try the old fashioned computer restart and see what happens. If all else fails, I can unplug it from the wall and blow on it, lol.
I swear, I've never been this simple before.

I was thinking that maybe the latest OTA broke the bootloader unlock process, but someone else in this thread said they just unlocked theirs. I don't understand what the issues is. I've followed this video so closely I could re-enact it in my sleep.
Got it! I had two sets of drivers installed so I uninstalled both and it finally recognized my phone in fastboot. My old drivers from my m8 from 2014 were probably interfering with it. I knew it was something simple. I feel like Carl in Sling Blade when they bring him the lawn mower engine and he says "ain't got no gas in it, mmhmmm".
Nice! For a noob I wasn't too far off lol it just had to be one of those two issues
Enjoy happy rooting ?

Flashing stock image error message help

Apologies for this being a bit long but hopefully this shall explain all issues.
I am trying to flash android 8.1 onto my RP2, I did flash pie onto the phone just to see if I could which it worked flawlessly first time no issues, I switched off my pc and that was it for a few months. When I went back to this to flash 8.1, I had to wipe my pc as the devices wasn't being found in fastboot only ADB, so done all of that, reinstalled ADB drivers and all running smoothly as it reboots from CMD, but when I tried flashing, it came up with a long list saying system.img not found, there was more lines like this around 15? But with different .imgs saying not found, I then moved the file into where my platform tools are, it then half worked as it just wiped the phone clean not going to older firmware, has anyone else come across this?? Any help would be much appreciated. I'd like to know what I'm doing wrong as I want to downgrade my RP1 back to either 7.1.1 or 8.1
would really love help aswell.

Make sure you are running the command prompt from platform-tools and all up update files are in the platform-tools folder and not in a folder inside platform-tools ...also try. "fastboot flashing unlock_critical". Even if you have an unlocked bootloader then install the firmware by typing
"flash_all" and just wait even if it looks frozen
flashing stock rom CRITICAL ERROR Black screen
I followed all guidelines including fastboot flashing unlock_critical. Everything was flashing fine & it got to a point where it rebooted & now all i have is a black screen it will not turn on or go to fastboot at all screen is completely black. If I am hooked up to my pc and try the combo buttons for fastboot my computer makes a sound as it would with any device attached. Please tell me i didnt totally brick my phone. I would appreciate any help!
The phone shows up in the device manager as qualcom hs-usb qdloader 9008 (com 8). Theres gotta be something i can do.
