Cant flash TWRP, "device not recognized" - Elephone P9000 Questions & Answers

I have the MTK drivers installed, when I plug in my phone, it pops up in device manager as "MediaTek preloader usb vcom (android) (com3)" which I believe is exactly what it should say, but there is a yellow caution sign next to it as well as an error on my taskbar stating the device is not recognized.
I have tried to flash anyway and the flash tool just refuses to find it. Ive uninstalled the drivers and reinstalled 100 times, manually pointed to the drivers, tried power+vol up, which gives the most action in the flash tool followed by an error.
upon inspection of the driver under device manager I am presented with an error under the log which I believe is the reason it is saying it is unrecognizable the error is "The USB device returned an invalid serial number string descriptor."
I been at this thing for 2 hours now... any help is appreciated!!!

problem solved.... I just booted up Ubuntu and flashed twrp from there. no problems whatsoever.

[Q] Trouble being recognized. :(

Okay, so I am attempting to flash back to stock, or anything that WORKS at this point.
I can get my phone into download mode and I connect it to my computer, but I get a rather annoying bubble that says "USB Device not recognized... one of the USB devices connected to this computer has malfunctioned and Windows does not recognize it."
I goto device manager and check my USB devices and it is listed as "Unknown Device" I look at it's properties and see "Windows has stopped this device because it has reported problems. (Code 43)"
So, I check the driver details.
It says "No drivers are required or have been loaded for this device"
So I goto update drivers, browse to where I keep them and see "Windows has determined the drivers for this device are up to date."
I have reinstalled all my drivers using various methods. I have tried new USB cables and all of my USB ports.
No matter what I do ODIN won't see my phone. Nothing shows up under any of the usual COMs
PLEASE HELP! WHAT SHOULD I DO?! D':

If you're running anything Gingerbread, you need to download and install the Nexus S Drivers to get your pc to recognize your phone in dl mode.
Didn't work. Could you link me to the the drivers?
I got mine from androiddrivers.net/samsung-android-drivers/download-nexus-s-drivers/
I GOT IT!
Upon taking a closer look at things.... literally. I found a very small piece of what appeared to be pocket lint lodged in my phone's port. Pulled it out and immediately regained functionality! SO, words of wisdom from hours of frustration "Look in the hole"

Those are probably the right ones, however I got mine directly from the drivers folder in thr Android sdk gingerbread update. Are you getting an error when you try to install the drivers you downloaded?

Driver problem

Need a little help here. I cannot get my phone to connect to my computer, I'm running Windows 7. I have kies installed and have also downloaded the drivers directly from the Samsung site, but still cannot connect. When I plug in, it says installing drivers, but then gives me an error.
If I go to Device Manager, I see SAMSUNG Mobile MTP Device but with the yellow exclamation mark. Under driver details it shows the correct driver installed, but has a Code 10 Error. "The Device cannot be started".
I've rebooted comp, rebooted phone, toggled USB debugging, uninstalled and reinstalled drivers, tried 2 different USB cables, and nothing is working. Anyone have any ideas?
I didn't have to do everything you listed to get it to work, but I did have to run the installer (T-Mobile_T999_GSIII_Samsung_USB_Driver_v1_4_6_0.exe) twice to get it to work.. it failed the first time.
I just unplugged and then plugged cable back in, ran the installer and installed again over old drivers.
You can also try going into Device Manager, right-click on the phone and "Update Driver Software" manually... installer extracts all drivers to the C:\Program Files\SAMSUNG\USB Drivers folder.
Still no luck. It installs the Samsung USB modem drivers fine and shows the phone correctly, but fails on the MTP Driver section.
Just for future reference for anyone that comes across this while searching. I did get this fixed. I tried a couple more usb cables and a friends computer with the same issues.
What I ended up doing was a factory reset on the phone. Plugged phone in after first boot and mtp drivers installed right away.

MediaTek DA USB VCOM Port - Help me fix Code 10 problem

Need to uninstall device and reinstall drivers
If you google, "Code 10", you will find that on a Windows system it is an error code generated by the Device Manager "because it can not start a device". In a nut shell, the most likely cause for this is because the device was not properly installed with the right drivers.
If you are running Windows, you can try to use the attached file called USBReview to see what device that is as you know it is your phone. Basically, with this program you can remove all the old drivers and start all the driver installation again.
Try to find your phone either here on xda, on the web or contact your phone's manufacturer - you need drivers!!!
Good luck, Mr. Phelps.

Your USB program does give a lot of information I have never seen before, but I still haven't been able to figure out how to get the driver to load.
thanks, John
I'm having the same problem installing the MT6575 USB VCOM drivers. Is there a workaround to get this installed? I"m using WIN 6 64bit

This is what worked for me after lot of experimenting and searching:
- get MTK6575 drivers (for instance from Bruno Martins where he writes about flashing mtk6575 - google: MT6575 flashing tutorial bruno
- Start c/windows/system32/hdwwiz.exe (as admin)
- Click next
- Manually select hardware
- List all devices
- Select the driver (for example usb2ser_Win764.inf)
- from the List select "MediaTek Preloader USB VCOM Port"
(or you can install other drivers from the list if Preloader is not enough..)
On another computer I solved it by installing whole Android SDK, checked my android system and installed updated for SDK (approx. 2 GB) and it installed correct drivers automatically.
Also you can experiment with using another usb port..
Please write here if it helped.

Just ignore the error Code 10! Start the SPFlashtool and load the scatterfile, click on download and connect your switch off Phone with the computer. It will work fine.

Did you ever get this problem solved as I have the same issue with an MTK 6592 chip based phone?
I have the same problem too.
Installation of Media Tek preloaded drivers gives me Code 10 error.
Has anyone found the solution?
my phone is totally dead without power now after I tried to flash with SP Flash tool using correct ROM. I noticed in device manager that there is a CODE 10 error in mediatek preloader usb driver.. is this the culprit? my phone can no longer be detected now in SPFlash or MTK Droid tools... so hopeless... this is a brandnew phone I bought to be given as gift to my cousin...
I did it! I did it! I did it!
The solution is... we need not MediaTek USB VCOM (Android) (USB\VID_0BB4&PID_0005&MI_02), but PreLoader USB VCOM Port (USB\Vid_0e8d&Pid_2000) !
I have MTK6582 (KingSing S2), the host - WinXPx64.
It looks like my phone (and, maybe, other MTK devices too) have several engineering modes.
I have spent several hours trying to get working VID_0BB4&PID_0005&MI_02, which is exposed, if device is turned on while holding VOL- pressed. In this mode some strange factory mode with nonfunctional menu items is displayed on the screen. But to activate mode with Vid_0e8d&Pid_2000 some trickery is necessary.
Sometimes this USB interface starts repeatedly to appear and disappear every half-second in infinitive loop. I had such situation once, when connected turned off phone to USB cable with battery removed.
I just literally catched MT65xx Preloader by double clicking on it in windows device manager and pressing "install drivers" in it's properties. I have used Driver_Auto_Installer_v1.1236.00\SmartPhoneDriver\x64\Infs\usbvcom.inf from http://spflashtool.com/download/Driver_Auto_Installer_v1.1236.00.zip. DriverVer = 12/24/2011, 2.0000.0.0
After clicking "Read Back" in Flash Tool this insane loop stopped and program started to function as intended.
This interface could also appear once and for very short moment, if turned off phone (with battery inserted) is just connected to host. Also it could be seen again, if power button is pressed. If "Download" or "Read Back" is not pressed in advance in Flash Tool, than boot will continue after smaller than a second pause (if device is functional).
I don't know if running Install.bat (from archive I have given above) is necessary. It didn't installed driver when Vid_0e8d&Pid_2000 wasn't active, but, I guess, running it during short blinks would give the same effect.
Also, I don't know, if advice given in comment#6 in this thread four years ago would work. Maybe, the fault was in older version of driver (DriverVer=05/30/2011,1.1123.0).
Another reason could be that necessary USB interface disappears before windows manages to install driver for it for the first time. Possibly, only if "catched" in device manager, user could manually assign driver to it.
I've been struggling with my UMI Rome for days. It has/had the black screen problem, sometimes won't enter recovery mode, sometimes wouldn't allow charge, sometimes works just fine (yesterday). Last night i mistakenly cut off power during a battery recharge. -- today it has all the above problems (bricked) so I am trying doing a flashing again using the tutorials and tools on the Tehnotone.com site. Sintetix's reply above helps me at least have a better clue on what is going on. Wish me luck! BTW, I am using a Dell Windows 10 pc. (Results to be reported here.)

I tried what you said. It wouldn't install properly. It kept saying error (code 10) and showed in device management with a caution sign every time I installed the driver. I disabled the forced driver signature thingamabop but it still does it. I guess I'm screwed. Has anyone else fixed this?

Star x26i bricked? SPmultiPortFlashDownloadProject

Hello
Last week I became my Star x26i. Its quite a very good phone, but because of WiFi and Battery issues i tried to update it to a newer version, like in this tutorial :
http://forum.xda-developers.com/showthread.php?t=1680338
So I used a program, calles SPmultiPortFlashDownloadProject
Everything went fine, but after the program erased the emmc Windows tried to install a new driver and failed. The program stopped and now the phone cant boot anymore (understandable with an formatted eemc...) The Pc detects the phone anyway, first as an unknown device and after installing a new chipset driver as "MediaTek DA USB VCOM Port (COM6)" If I try to reflash with the same program it gives me following issue like on this picture: http://imageshack.us/f/856/erroroly.png/ (Error: No Bootrom USB Port was found! COM6 is not a Bootrom (preloader) USB Port. Auto polling Number0.
Are there any Chances to rescue this device or is it totally bricked? Thanks in advance...

Accidentally removed USB while flashing ROM through SPFT

Help! As what the title says, my computer can't recognize the phone after, and I can't flash through spft and my phone doesn't boot up. I looked through the device manager, and it says "Unknown Device". I tried uninstalling the mtk driver and restarting the pc, but its no use I also tried updating the mtk driver again with the same mtk driver, but the pc says it is up to date.
Is there any way to recover my phone?
