Oppo R7 Plus | Stuck in boot | Tried to root with "Oppo Tools" - Oppo R7 Plus

Background
Oppo R7 Plus bought from Oppo Europe, should be the F version of Oppo R7 Pus. Wanted to root the device and tried to do so with the "Oppo Tools" app. After root, the device was unable to start again. It is stuck in boot sequence (logo screen during startup).
Investigation to get the device to work again
Install stock ROM with ColorOS Recovery
Possible to access ColorOS Recovery.
Not possible to install any ROM since ColorOS Recovery can only access the internal SD card. Can only transfer files to external SD card.
Install new ROM with DownloadTool
Device won't be correctly connected to PC. Just to add that I am using a PC with Windows 8.1 Pro installed.
Connected the USB cable to the PC when pressing “VOL+” and the device appear as an Unkown USB Device (code 47) in Windows Device Manager.
I tried to run "OPPO USB Driver 2.2.6.0.exe" to get USB drivers installed. Did not work so i tired to install the "Qualcomm Driver V1.0.79" instead, but still no luck. Unknown USB Device (code 47)...
Tried to add a key in regedit to solve this, no luck:
https://forum.xda-developers.com/android/general/fix-unknown-usb-device-device-t3375320
Connection problem described above was solved by changing PC (Windows 7) and a different USB cable.
Solution
Put the phone into download mode (connect the USB cable to the PC when pressing “VOL+”)
With proper USB connection to the device, it should appear as a qualcom device in the Windows Device Manager
Stock ROM could be installed with the download tool (Msm8x29Download Tool v.1.6.8)

Need Help For the TWRP..!

Hi.. I just saw the new TWRP and liked it alot!. So i downloaded the TWRP for Trebon and also downloaded the Odin3 on my pc. And then i put my phone into the download mode and connected by USB. But the ID COM box wont come up.. The ODIN3 is just not detecting my phone .. Dunno why..
I tried installing drivers for my phone but it didnt work.
I also installed Kies after that but no use.. I used 2 versions of Odin3 i.e. Odin3 v1.85 and Odin3 v3.x.. But still its not detecting my phone..
So can anyone pleazz help!!
(Using SGA+ with the cm10)
are you sure you installed the drivers
* disable or remove kies
* Install drivers again (windows) select correctly 32/64 bits
or try this simple method.
INSTALLATION 1:
0. Uninstal previous Samsung USB drivers from Control Panel and Device Manager.
1. Unpack the .rar archive and run the installer from "SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.20.0\setup.exe" and proceed with the installation steps.
2. Switch your Samsung phone into download mode
3. Connect it to your computer via USB cable.
4. If your phone is still not correctly recognized by Odin - try the second method.
INSTALLATION 2:
0. Uninstall previous Samsung USB drivers from "Programs And Features" and "Device Manager".
1. This is the "have disk" method. You have to follow every step in this guide.
2. Unpack SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.20.0.rar to some location, eg. C:\.
3. Switch your Samsung phone into download mode.
4. Connect it to your computer via USB cable.
5. Your phone should become discovered by Windows as some device. In my case, Windows has found my SGS i9000 as a "Gadget Serial" device.
6. Go to Windows Device Manager. Right click on the device your phone has been discovered as (eg. "Gadget Serial" in my case) and choose "Update driver" option from the context menu.
7. Choose "Search my Computer...", check "Include subfolders" option and point the updater to the folder where you've had unpacked the drivers .rar archive to, eg. C:\SAMSUNG USB Drivers for Mobile Phones (x86 & x64) v1.5.16.0.
8. The driver should install automatically.
9. It may happen that after the installation some new "unknown device" ("Samsung Modem" in my case) would appear in the Device Manager. Complete 6 & 7 step for that device and any other new device that may appear afterwards.
10. Restart your computer.
11. Done!

[GUIDE I9500] [SOLVED] MTP device driver error 10 FIX

Please notice: this has been done on i9500 device. you can try it on your i9505 it 100% not dangerous, but I dont know if its working
Well im using i9500 custom rum running android 4.2.2 and I had a problem: whenever i connect my phone to PC it says: "unknown device MTP device driver error 10 device can not start."
METHOD 1:
**make sure your device is disconnected from the PC.
** make sure that usb debugging is enabled (go to 'developer mode')
1) Open Xposed Installer and go to Framework and UNINSTALL it.
2) reboot your phone. (NOT soft reboot- full one).
3) On your PC, go to "driver manager" and under "universal drivers" section, delete "unknown device". (right click-> delete)
4) restart your PC.
5) connect your PC to the computer, it should work now.
6) you can now reinstall Xposed module. reboot your phone (again- not soft reboot) and reconnect it to your PC just to make sure its still working)
METHOD 2:
STEP 1
**MOST CRITICAL: Update ALL your PC drivers using driver software I personally use 'advanced optimizer pro'. UPDATE YOUR BIOS AS WELL! [/COLOR]
- Update drivers using a software.
-Update your bios.
-Download windows updates (start->type 'windows update' in search bar, click on 'windows update'-> 'check for updates'. dont forget to check optional update as well').
dont forget to restart!
now after you are sure both bios and drivers are up to date, try the following
STEP 2/2
- I downloaded and installed samsung drivers
-Try to connect your phone with ANOTHER cable.
-Try to connect your phone to ANOTHER port (this can indicates where the problem is: maybe the cable/port is corrupt)
-I tried deleting ALL samsung drivers and reinstall
-tried connecting my old s1 i9000. try to connect another phone to see where is the problem- phone or maybe computer.
-try to connect phone while its in 'download mode' and recovery mode.
-try running windows error kit.
-download Android ToolKit.
- if non of the above are working, you can always try FULL WIPE+ REFLASH ROM . (or try flashing another rom).
*if its still not working ever after performing all the steps above under method 2, try restart your PC and try Method 1 AGAIN WITH A DIFFERENT PORT AND CABLE. there might be a chance that you have a 'combined' problem (several issues that preventing from your MTP driver to work properly.
After downloading drivers you can be sure 100% ALL YOUR PC DRIVERS ARE PERFECT, try Method 1 again.
METHOD 3
***Coming soon on next update
worked for me with:
custom android 4.2.2 OzcanRom all version including v5.0 according to sep 20 2014.
stock kernel. no system files have been ever modified
working with android 4.1 and above.
Windows 7 SP1 64bit Updated Sep10 2014.

yup im talking about the device manger. i will update the thread soon.
you may find one of the following with an error:
1) universal bus controller.
2) MTP driver failed
try to update both of them or uninstall them
tomorrow i will upload METHOD 3
plus method 4 is on its way..
Method 1 No5 -typo
You will connect your phone to the PC, not the computer to the PC...
Also, updating a BIOS is not straight toward and can cause a bricked pc. Be careful advising people to do that

Soft bricked Panasonic P81

Hi Friends,
This is my first post at XDA.
I unfortunately bricked my Panasonic P81 after rooting it and adding XHalo app and the boot manager app from the Xposed Framework.
The situation is as follows-
I can get to the logo, it screams Panasonic and then doesnt boot. I dont have CWA installed and worse, my SD card which had my stock backup is also lost. This means I need a mechanism to stock recover and perhaps flash boot.img and recovery.img?
I am stuck at this point, not sure how to proceed. I can get to recovery, have cleaned cache, backed up user data ,done a factory reset. Even after factory reset it still cant boot.
Please help me with a step-by-step instruction to recover, this phone is dear to me. How do I flash?(boot.img or rom) I have downloaded Sagar Patel's (good bless him!) backup and the images, but need guidance on how to flash and recover.
Please help friends and apologies for any incovenience. I am still a newbie
Guys please help!!
Driver-USB-PC connection problem

Guys please help!!

Hope drivers are installed properly in your pc.
If you are going to use sp flash tool, Make sure SP flash tool is set to auto-detect com port, not manual selection
If you find that it is driver problem, following may help you.
Please note that there is nothing that much hard in driver installation as it is just to connect your device with your pc but because many users still face problem of driver installation, you can try following tricks!!!
It is observed by me that driver installation and adb interface problem do not happen in windows XP as eventually and generally it is happened in windows 7 and later…so, you can simply try on windows xp if you are able to do so…(you can use dual operating system too!!! Or good relation with neighbor/friends/colleagues/someone/all can be beneficial here!!!)
Note that all tricks here are not necessary to work, but it may still work for you….
Take one by one step, if the first step does not work for you, only then try next step. This is not all steps to be taken at once type guide…This is simply Try and error type tutorial/tricks…
There are following problems I have come to know regarding to driver installation and conflicts:-
Device is charging through usb cable but there is no usb option displaying on either device or no driver installation box/message/pop up appears in pc….
Missing sound of that usb-pc connection
Sound of disconnection after couple of seconds of connection
Adb interface is missing
Ok, sometimes changing usb connection type for example, from mass storage or mtp to camera, ptp, usb tethering or something else can bring adb interface…..
Try with different USB Cable. You can use original nokia or samsung tiny cable instead of cable having long length. Sometimes, length matters!!!!
Try in different USB Port.
Sometimes, you have to disable signature verification in your pc for proper installation of driver.
Had you disabled your antivirus before downloading, installing and while running your tools/softwares? You may need to do so…
Have you installed the software (or say, all associated softwares/tools) in C-System drive?, if not, then you should first install required software/tools in system drive that is usually C drive in Microsoft-Windows OS…or try after installing them on desktop.
Keep all necessary files/tools (driver files, flash tools, rom etc…) on desktop.
Download proper driver According to your model/device, According to chipset inside, According to Official site of manufacturer, Official site of chipset, through PC Suite/flash program of your device…
If the problem still not solve, you should try all available driver packages of your device one by one whether from official site of chipset inside your device, or any forum, adb, pdanet+ or foxfi, universal driver, VCOM Port driver, drivers from hexamob through play store, and find all possible packages and see if someone make positive result after installation…
If the problem still not solve, you should install remaining update packages of your system (PC) including all primary, secondary, essential, Non-essential updates….whatever, just install them all….reboot your pc…and see if problem is solved….
If you can connect the device but somehow found that device driver still not installed properly, just go to device manager in your pc, click on portable device, right click on your device and apply “Update driver”. Click on “automatically search” when a window prompt ask you.
If the problem still persists then,
Just remove all the drivers using usbdeview (I have given link also to download usbdeview in earlier post)
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Install usbdeview and remove all the drivers
You can also fix this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
Use Usbdeview to uninstall all the drivers before connection, restart the pc, Extract and keep driver zip files and other useful files/tools on desktop…just start your tool… and try to perform your tasks like backup…or restoring the backup…without worrying about that sound of disconnection you may listened after couple of seconds of connection or don’t even worry if you are just missing that sound of usb-pc connection….just try on your tool…
If still problem of driver installation persists, then simply use usbdeview and uninstall all drivers, restart your pc and try following steps:-
There are various ways to install proper drivers at the time of connecting the device with pc depending upon how you connect it.
Follow the procedure both with and without battery
Simply plug in via USB Cable
Connect by holding volume down button
Connect by holding volume up button
Connect by holding Power button
Connect by holding power and volume down
Connect by holding power and volume up
Connect by holding both volume up and down button
Connect by holding thrice volume up, down and power button
Connect by holding power and home button
Connect by holding power and menu button
Remember which method works and which drivers are installed
in LAN-Devices you may have different android device
Select/set drivers by hand and use the mtk usb driver, now Flashtool finds the phone
Suppose holding volume down method without battery works for you then what next you have to do is as below:-
1.TAKE THE BATTERY ,SD ,SIM OUT OF THE PHONE
2.HOLDING VOLUME DOWN CONNECT IT TO PC VIA USB(ONCE YOU HEAR A SOUND FROM PC YOU CAN RELEASE VOLUME DOWN)
3.OPEN DEVICE MANAGER(ON COMPUTER SEARCH IT OR CONTROL PANEL)
4.WAIT FOR 2-3 MINUTES
5.YOU WILL HEAR A SOUND & OTHER DEVICE WILL BE DISPLAYED
6.IN OTHER DEVICES ->MT65XX PRE-LOADER
7.RIGHT CLICK MT65XX PRELOADER
8.UPDATE DRIVER
9.LOCATE THE DRIVERS PROVIDED ACCORDING TO YOUR OS(VISTA,WIN7,XP)
10.IT WILL DO ITS STUFF
Install Mediatek drivers, preloaders, VCOM port etc…
Manually Install MediaTek USB VCOM Drivers
Requirement:-
1. Download MediaTek USB VCOM Drivers
2. Download USBDeview
Here is the link from you can get it:-
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Procedure
(* Note: You might need to disable drivers signature verification in Windows for this to work smoothly.
If you want to turn off device driver signing in Windows completely, do the following.
Windows 7:-
1. Hit the Win+R keys together to open the run dialog
2. Type gpedit.msc to open the local groups policy
editor
3. Expand ‘Administrative Templates’ (it’s under ‘User Configuration’)
4. Expand ‘System’. Click ‘driver Installation’
5. In the right panel, double click on ‘Code Signing for Device Drivers’
6. Choose ‘Enabled’ in the window that appears.
7. In the underlying options, choose ‘Ignore’
8. This disables drivers signing in Windows 7, and now you can install unsigned drivers in Windows 7.
9. Click Apply, OK. Restart your computer to install unsigned drivers
Windows 8
1. Hold down the Windows key on your keyboard and press the letter C to open the Charm menu, then click the gear icon (Settings)
2. Click More PC Settings
3. Click General
4. Under Advanced Startup, click Restart Now
Note: In Windows 8.1, the ‘Restart Now’ button has moved to ‘PC Setting -> Update & Recovery -> Recovery.’
5. After restarting, click Troubleshoot
6. Click advanced options
7. Click Windows Startup Settings
8. Click Restart
9. After restarting your computer a second time,
choose Disable driver signature enforcement
from the list by typing the number 7 on your Keyboard Your computer will restart automatically.
10. After restarting, you will be able to install
unsigned drivers normally; however, Windows
will display a warning message. When the
warning appears, click Install this driver
software anyway. )
1. Install USBDeview and use it to uninstall all Vcom, Mediatek and Preloader drivers
1b. Extract the contents of the Mediatek USB VCOM file
2. In Windows, go to Control Panel and open Device Manager
3. Click any of the device groups (any of the items on the list) you see there, and then from Action menu, select Add legacy hardware
4. Add hardware wizard will be opened, click next
5. Select Install the hardware that I manually select from a list (Advanced)
6. Click next two times and click Have Disk button
7. Click browse and find where your driver's .inf file is, then select it (the .inf you'll select is located in drivers > USB Vcom driver > your OS) . Ensure to select the 64 bit .inf if your PC is 64 bit
8. Click Open and OK. You will see the drivers listed.
9. Select your driver there (select Mediatek Preloader USB VCOM Port)
10. Click Next and finish installing
11. If SP flash tool or other software still dont detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be)
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Case:-
It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.
Guess what? Once my Panasonic P81 could install driver and got detected after approx. 5 hours of continuous connection with win 7 x64!!! Meanwhile, I tried first usbdeview and then manually installation of mediatek driver but manual installation had failed as my p81 was only charging when it was connected with pc….So, mediatek – windows 7 conflicts….but, when I tried tiny (very small) nokia usb cable, it works instantly…
If you ever meet problem when you connect your android with your pc via usb cable and find that your android is charging but could not recognize or there isn’t that options of “USB connection” then just disconnect your android, power off it, remove battery, connect it without battery with your pc through usb, let it have some time to recognize your android or hear that voice of “usb connection” you were just missing…after that, insert battery and switch on your android…you are done!!!
Sometimes removing both sim cards and battery and then re-inserting them after a couple of seconds also works.
Try with different USB Cable
Try in different USB Port
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Use usbdeview to remove all the usb devices and then add your device

In my opinion MIUI is best because it has a self large community like xda and launch updates per month so many that you will fed up installing them.....if you download and install one update you will be amazed that it will say 3 more system updates pending......and if you complain a bug next month it got fixed.....only thing is to find one...
PS don't download the miui 6 for p81..complained by many p81 user that it hard bricked the device.
And that miui is not official i.e. some developer made his own one and DO not tested that it works or not......

(Or last save from: "BootLoop/Error > QFIL Flash > Lenovo Stock 5.0.2 K920_S288_160224_ROW")
!!! Warning: You will lose all your data not backed up before flashing firmware !!!
! I am not responsible for bricked devices, everything what you do is at your own risk !
! This will also relock Bootloader, restore Stock Recovery, remove ROOT and format Internal Storage !
Installation instructions QPST firmware using QFile Flash:
1 - Install the necessary drivers ("ADB Drivers", "Lenovo USB Drivers" and "Qualcomm USB drivers")
2 - Activate the "Developer" menu on your phone settings (10x Double-click "Build number" in the "Settings>About Phone")
3 - Enable the "Debug Android" in the "Settings>Developer"

Will be displayed at the top of the bar in the "QFIL" following information "HS-USB QDLoader 9008 (COM XX)" instead of the original "No Port Avaiable" announcement
11 - After installing the drivers release the "Volume +" and let the phone reboot himself
12 - Verify the correct installation of the drivers in the "Device Manager" on your computer, it needs to have the following items:
"Lenovo Composite ADB Interface" under ADB Android Device, "Lenovo HS-USB Modem Phone" under Modem, "Lenovo HS-USB Diagnostics" and "Lenovo HS-USB NMEA" under COM/LPT ports.
If you see such headings you have all the necessary drivers installed, disconnect the phone from the USB cable and then switch off
13 - Unzip the downloaded file "K920_S288_160224_ROW_QFIL.rar" and copy the entire contents of the folder to "C:/"
14 - In the program "QFIL" fill for "Programmer patch" by select "Browse>prog_emmc_firehose_8974.mbn" from "K920_S288_160224_ROW_QFIL\SW"
15 - Under "RawProgram" select "Load XML>rawprogram0.xml"
16 - Following the "Patch" select "Select patch file>patch0.xml"
The result should look like in the picture below ...
17 - Now again press and hold the "Volume +" and connect the USB cable to the switched off phone
18 - In the moment when when you see in the "QFIL" at the top bar notification "Qualcomm HS-USB QDLoader 9008 (COM XX)" you must immediately start the firmware upgrade by selecting "Download" until cca 3 seconds and then release the "Volume" button, when nothing happened, repeat step again from a point 17
19 - Wait for the process is complete (about 2-5 minutes) then after restarting the phone disconnect the USB cable
20 - If everything went smoothly you now have the original "Lenovo K920_S288_160224_ROW" firmware on your phone

Hi
do phone have to have cm12.1 rom when following these instructions, or can it be any rom?
No matter what the ROM or an Android version is used on phone.
But remember that all DATA on all partition will be deleted (Internal Storage include)!!!
Make backup of everything important before you will start...
c.x
cant install quallcomm driver to win 10, probably therefore QFIL say "no port available"?
Which version of WIN10 do you use? 32bit or 64bit?
Click on the "*.inf" file in the "Qualcomm_USB_Drivers\Checked" directory and choose "Install"
Otherwise, QFIL always shows "No port available" until you connect phone into USB port and wait for install all necessary drivers...
c.x
thanks
I have win10 32bit. I tried to do like u said, but it gives me error "a problem was encountered while attempting to add the driver to the store"
There are 3 install files, choose every file in directory "Qualcomm_USB_Drivers\Checked\x86" or "Qualcomm_USB_Drivers\Free\x86" (qcmdm.inf, qcser.inf and qcnet.inf). You have to be login as Administrator in WIN10.
What happen when you connect your phone and run "QFIL"?
(I mean like in step: 10 - Press and hold the "Volume +" button and connect the USB cable to the switched off phone (will switch to service mode which allows installation/reinstallation Qualcomm drivers))

That's all right! You have already installed drivers on your PC, now you can continue with my guide from step 13.
Good luck, mate!

mate my phone is dead, i can only see lenovo logo, cant access recovery mode,will this work for me,i mean when i cant access usb debugging in setting.
If the QFIL utility can recognize your phone in service mode and you have installed the all necessary drivers then it will work...
You can try it and write result.

So i'm here too, my vibe 2 dies when installing last android update OTA, i didn't root, unlock or install any custom roms, now i can enter in some recovery menu and some test menu, i read your install guide but i don't know where to start, i have a brand new win10 32bit and the phone never been connected to the pc, so there is no lenovo drivers on it, my question is can i use your guide to reinstall official lenovo firmware ? and steps will be very useful.

How to revert back: "CyanogenMod > QFIL Flash > Lenovo Stock 5.0.2 K920_S246_150520_ROW"
(Or last save from: "BootLoop/Error > QFIL Flash > Lenovo Stock 5.0.2 K920_S246_150520_ROW")
!!! Warning: You will lose all your data not backed up before flashing firmware !!!
! I am not responsible for bricked devices, everything what you do is at your own risk !
! This will also relock Bootloader, restore Stock Recovery, remove ROOT and format Internal Storage !
Installation instructions QPST firmware using QFile Flash:
1 - Install the necessary drivers ("ADB Drivers", "Lenovo USB Drivers" and "Qualcomm USB drivers")
2 - Activate the "Developer" menu on your phone settings (10x Double-click "Build number" in the "Settings>About Phone")
3 - Enable the "Debug Android" in the "Settings>Developer"
4 - Connect your phone to your computer using a USB cable
5 - Wait until Windows installs a device driver (this may take a while)
6 - When you connect your phone to your computer confirm the "Always allow from this computer" if the message appears
7 - Unplug the USB cable and turn off the phone (after installing the drivers)
8 - Install "QPST_2.7.422" tool
9 - Run the installed program "QFIL" ("Start>All Applications>QPST>QFIL" (Windows 10))
10 - Press and hold the "Volume +" button and connect the USB cable to the switched off phone (will switch to service mode which allows installation/reinstallation Qualcomm drivers)
Will be displayed at the top of the bar in the "QFIL" following information "HS-USB QDLoader 9008 (COM XX)" instead of the original "No Port Avaiable" announcement
11 - After installing the drivers release the "Volume +" and let the phone reboot himself
12 - Verify the correct installation of the drivers in the "Device Manager" on your computer, it needs to have the following items:
"Lenovo Composite ADB Interface" under ADB Android Device, "Lenovo HS-USB Modem Phone" under Modem, "Lenovo HS-USB Diagnostics" and "Lenovo HS-USB NMEA" under COM/LPT ports.
If you see such headings you have all the necessary drivers installed, disconnect the phone from the USB cable and then switch off
13 - Unzip the downloaded file "K920_S246_150520_ROW_qpst.7z" and copy the entire contents of the folder to "C:/"
14 - In the program "QFIL" fill for "Programmer patch" by select "Browse>prog_emmc_firehose_8974.mbn" from "K920_S246_150520_ROW_qpst"
15 - Under "RawProgram" select "Load XML>rawprogram0.xml"
16 - Following the "Patch" select "Select patch file>patch0.xml"
The result should look like in the picture below ...
17 - Now again press and hold the "Volume +" and connect the USB cable to the switched off phone
18 - In the moment when when you see in the "QFIL" at the top bar notification "Qualcomm HS-USB QDLoader 9008 (COM XX)" you must immediately start the firmware upgrade by selecting "Download" until cca 3 seconds and then release the "Volume" button, when nothing happened, repeat step again from a point 17
19 - Wait for the process is complete (about 2-5 minutes) then after restarting the phone disconnect the USB cable
20 - If everything went smoothly you now have the original "Lenovo 5.0.2 Stock K920_S246_150520_ROW" firmware on your phone
