hi guys,
I've Lenovo TAB A5500-HV i used MtkDroidTools to create backup which located in my PC, and tried to install the Offical ROM A5500HV_A442_000_024_141007_ROW using SP Flash Tool v5.1352.01 using the option Download, after it starts in about a second the windows - windows 8.1 x64 - just restarted and since then the tablet won't start neither normally nor in recovery and when it get connected to PC the windows says Unknown USB Device (Device Descriptor Request Failed) and no the Mediatek DA and Mediatek Preloader don't get recognized at all in the Device manager.
i know it's totally dead and i searched for long time on the internet with no luck.
PS: i say the device is MT6582 but Lenovo says it's 8382 and in the droid tools it says 8382 is a fake so i don't what it matter
thanks.

Hi
I flashed the phone with invalid firmware using SP_Flash_Tool.
Now SP_Flash_Tool and Windows doesn't see the MT65xx Preloader USB device after disconnecting/reconnecting the battery.
The phone doesn't switch on.
Is possible to recover a preloader on MTK6577 (Zopo ZP 900) using the flex cables or other methods?
Thank you

MTK6577 Tablet
Hey guys .. any solution ?
Lenovo A2107A-H, Dual SIM dead after SP-Flash
I stand in a row with you all, I also have killed my tablet with SP-Flash, It appears as Alcatel Single RNDIS Interface in Win7 control panel's network adaptors and in Win8.1 as "unknown device". I already uninstalled the drivers, the Win7 needed to reboot after that, but re-installed the same sh** after reconnecting. I have heard about another tool, not SP-Flash, which shall be able to "find" the tablet on the USB bus, but I don't remember the name.

I un-bricked my Lenovo P770 yesterday!
How to do this:
1) Download and install "MT6577 USB VCOM drivers" -drivers for your phone
2) Open Device manager in your computer. Then "View" and "Show hidden devices" (do not close Device manager)
3) connect your phone to PC by USB cable (without battery, some phone with battery)
4) In device manager, in Network adapter (in my situation, after few second) shows "Alcatel single rndis interface #. . ." - it can appears and disappears!
5) When "Alcatel single rndis interface #. . ." appears click on this device Update drivers->Browse my computer...->Let me pick.. and here you should see "Mt65xx Preloader" if not you should find your driver.
6) When you update this driver you could use Flashtool v3->loading scatter file (you can find your android on needrom website. for example: P770_ROW_S110_130204_707WOW) -> check only PRELOADER and click Download
then connect your phone again to USB (without or with battery) and wait some seconds.
GoodLuck!!!

I have the same issue. mediatek S8 - mt6577 7inch tab
Hello,
*I have a problem with accessing phone PreLoader on Virtual COM port.*
I have NO PROBLEM with ADB driver and access. I can also access phone as a Device in Windows.
*But I want to create backup of my phone ROM.*
I want to read the ROM with SP Flash Tool to make backup.
(I cannot post links, so see full links in .txt file attached)
Phone: Alcatel IDOL One Touch Mini
Phone model code: 6012X
Full phone specs: gsmarena.com/alcatel_one_touch_idol_mini-5669.php
Chipset: Mediatek 6572
USB driver link page: developer.android.com/sdk/win-usb.html
Driver direct link: dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip
OS: Windows 7, 64 bit
What I do:
------------
- I turn phone off. (Cannot remove battery - phone can not be opened=battery is not removaable)
- Connect to Windows
- Windows popup message for a device connected !
- Browse... choose driver for Win7,64bit,..... (only first time Windows wants driver)
- In Device Manager this device appear for a second, and then disappears: [PreLoader USB VCOM Port (COM_X)]
=== Result: Phone is not visible and cannot be accessed/shown in SP Flash Tool. Tried in versions 3.1224.01 (older)
and 3.1352.01 (newer interface).
What I tried to troubleshoot:
---------------------------------
- Used USBDeview.exe (64 bit), runned as administrator. Performed manual Uninstall for all old virtual COM ports.
- Tried another USB cable.
- Tried another USB port; Tried another USB port on another insernal USB hub; Tried on extranal USB hub.
- Tried another drivers, which I have found on fourms.
- Started Device Manager as admin, show hidden devices. Now I can see m phone as a light gray device.
Every time I plug phone, Windows creates a new VCOM port. I have to uninstall them manually with UsbDeview.
When I click properties on VCOM with/without currently phone attached windows says:
"Device status: Currently this hardware device is not connected to the computer. (Code 45)".
See screenshot: postimg.org/image/o3h86dbzt/
- Googled many times for Code 45 but cannot solve this problem.
- Obviously windows can see MediaTek chipset at least for a while. Tried to connect on turned off phone. Or with
phone started in Recovery mode (Meta mode?) - Power+Volume up. No luck here too.
=== Result: Failed to succeed. Nothing of above can help.
Please, help!
Hi guys,

I'm trying to install stock rom to Lenovo a2016a40 (Lenovo B). After I connect phone to my system using volume down key preloder appears in device manager but after few seconds it disconnects from pc. I have tried to install via SP flash tool but it fails and gives error.
I have tried to update all mediatek drivers , changed port and cables but still I'm facing that issue , please help with this issue.
@sangram200
AFAIK Lenovo Vibe B is based on Mediatek chipset, hence SP Flash Tool seems to be the correct one.
It just disappeared from Device manager on PC
It simply disconnects from pc after few seconds ( disappeared from device manager), hense SP tool fails there is no issue with flash tool , its the connectivity issue but I don't understand why it disconnects from PC ,I have tried to update drivers and changed cables and switched ports but still having same issue.
@sangram200
I'm pretty sure you haven't installed the correct USB-drivers as needed, for example the MediaTek MT65xx USB VCOM Driver: this USB Driver will make sure that your MediaTek Android device is properly recognized by your PC, it ensures that there will be no hiccups while you are trying to flash a custom ROM or when you are trying to root your device.
