I got the same problem here
Can someone help ?
Thanks in advance
ignore this error
Ignore this message. If your PC has no other tablet drivers, it will flash. I end up using a pristine PC to flash a new ROM. The steps are correct. If you have no other PC, use USBDeview to delete suspicious driver.
Good luck.
I tried to downgrade the kitkat version because I couldn't update my apps, using a flash tool.
It then shut down and now does not turn on at all. When I plug into the computer the USB gets into a cycle/loop of connect and disconnect. Please help me if you have the time.

no. But I think it goes on '''META MODE'" ONLY on the computer for a few seconds.
Thanks for commenting.
Check device manager in your pc when you connect your phone, is it showing MTK 65xx preloader

I used this one.
forums (dot) lenovo (dot) com/t5/A-and-P-Series/Lenovo-A536-stuck-during-firmware-upgrade/td-p/1744571[/url]
I downloaded the latest firmware from
"THIS is the latest original ROW firmware (PC Flash Tool installation)"
This whole guide was fine, it worked for me.
But the problem was when I tried to downgrade the firmware to an older version.
I tried to replace the lastest official firmware with this one ROM Android 4.4.2 (older official needrom(dot)com/download/lenovo-a536/
sorry can't link websites yet

Thank you so much for staying with me to solve this problem. The phone is fixed.
I followed the
"
For MT6575/ 77
With the battery out, hold the volume up, don't let go & plug in the USB cable will activate META mode for few seconds...Typically, you need to click Download at SP Flash Tool before entering META mode or it will auto disconnected...
"
except I downloaded the lenovo a536 stock rom.
the only thing I did different was that I plugged in (META MODE) and THEN pressed download or else the usb would never be detected (they both show different COM numerals.)
After that I firmly held the whole usb into the phone during the whole flashing, or else it might get automatically disconnected again.
Then I updated/upgraded to the latest firmware, And it is all optimal. :good:
THANKS AGAIN !!!

I don't think you need to connect phone during installing drivers and phone will stay connected after properly installing DA Vcom drivers

Hi,
I'm new in this forum , and I'am a total newbie.
I bought a LETV X500 ans it last only a day , after reaching 4% battery , it shutted dow, since then the screen remain black , only the red led is on when I plug it to a computer or a laptop ( but it do not charge)
I managed to follow several tutorials.
I try to install mtk vcom drivers on 3 different laptops (Win 8 , XP , Vista)
the result is each time the same , I only have MTK USB PORT (COM X) When I connect my phone.
I read in the forum thatI must have Mediatek preloader usb vcom port to be able to flash a stock rom , however i do not have it.
When I connect flashtools ,and after cliking the download button , the phone connects and disconnects after half a second. So I am not able to flash any rom.
I tried to only donwload the preloader , by unticking every all items , but it seem the MTK usb port is too slow to load the preloader in my phone , and I have a timeout....
What can I do?
thanks for your help
come on guys , help a poor lad
Hi there XDA-developers
After trying to flash my device ZC550KL with Lineage 15.1 my phone became hardbrick, the phone wasn´t charging, no leds, no logo only a driver bulk under device manager.
After a research i decide to buy a EDL cable and finally found the firmware to flash with QFIL i install the qualcomm driver 64 bits and disable the drivers signatures on my windows 7, next i install the driver for qualcomm 64 bit and appears on my device manager the driver is installed (Qualcomm 9008). Then i decide to flash with qfil and went ok.
After the flash with qfil appear the leds of charging, vibrate, but still no logo.
Next i use Asus Flash Tool and use stock rom (ZC550KL_V12.8.10.56_M3.1.33_WW_Phone-user.raw) and flash with no erros under de software Asus Flash Tool but on my mobile nothing happens.
Now when i try to power up my phone appears a red light on the charging leds.
Any ideas in what i should do next.
Best Regards

========================================
My rog phone 3 (tencent), which i brought about 6 months ago. I never had any issues like this.
The other day i opened my camera and suddenly the front camera was not working. I restarted the phone, did factory reset, cleared camera data, but nothing solved the issue. I thought i have to upgrade the firmware. So i downloaded the new firmware (2012.143) and connected the usb c cable with my laptop ( lenovo ideapad 320) , but it did not recognize. i tried both ports. I never had this problem before. I unlocked the bootloader, i thought it might help. I also turned on the developer option and selected FTP protocol and USB debugging. But it still didn't connect. while i was trying to enter bootloader recovery mode I accidently put the phone on EDL mode and now its bricked . The indicator light is flashing when i connect to the pc but the PC isn't recognizing the port ( i downloaded the qualcomm EDL driver on my laptop also, but the port option is not showing at all). Is it hardware problem, But the phone was charging just fine.
please help, gaming is my life
