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.

Does it vibrates or display anything?

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 !!!

What do u mean by "it is constantly going off while installing"
Does it boot in recovery mode? Please be as specific as you can while posting questions.

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

Lenovo A536
Please help me guys, where is GND and COLO point of lenovo a536
same problem
i have a lenovo a536 and when i flash the stock
it goes to a cycle of off and on , help me to fix this
ive tried a lot of stock roms i searched,and none of them worked , the cycle of turning off and on is still there
hi guys, (LG-P920 is my Phone)
yesterday i installed ROM MANAGER to install CWRMOD (or something like that).
Then i choose my Phone Type and flashed it. After that my phone permanent restarts in 1 second,
showing LG Logo and restart, restart restart nonstop.
I understand that i ****ed it up with flashing that recovery mod. So i decided to Plug into my PC
and install everything new, but when i connect my phone to PC , it detects a unknown device every second and does it permanently too. I tried the "Battery out, Volume Button UP and connect" trick, then it stops acting weird but my PC
dont recognise my phone as OMAP, it is just an unknown device
What should i do guys? i tried installing LG Support Tool, LG Mobile Driver, and i read all the Instruction to UNBRICK your phone.
But all the Instruction starts with a successful regocnition of OMAP driver, but my PC dont even recognise it as OMAP.
PLS HELP
ok i fixed it, it was a really complicated move to 0.1 sec click that omap and install while my Phone was permanent restarting.
Hello.
I have a problem with my lenovo tablet
During flashing a older stock rom in, I selected incorrect rom and now the device doesn't boot.
Doesn't react to holding any combination of volume +/- and power.
Doesn't react to power button at all. If I plug it in to a charger, it doesn't show the charging animation.
SPFlashTool is unable to do anything after I pick the device, it sees it but is unable to flash it in. (I will attach logs after I get home)
Windows still detects a MT65xx Preloader after I plug it into a USB port. (I have removed the MTEK vcom USB driver since the flashing attempt)
Is the situation still salvageable? Can I somehow still give life back to my bricked device?
Thanks in advance.
Well, almost a year later I've bumped into the exact same issue.
Anyone knows how to solve this?
Damn...
----EDIT----
I've managed to sove this. Had to open the tablet and remove the cable that connects the battery. Once reconnected, the tablet was able to be powered on.

Bricked Lenovo Tab 2 A7 10F
I was trying to flash TWRP and get my Lenovo Tab 2 A7 10F to root but during the process i don't know which scatter file i chose since it the scatter files were more than 1.
So i tried one by one all of the three scatter files and tried to flash but I don't know which scatter file i chose. So i removed the USB from my tab since the bar at the bottom wasn't progressing and now the tab won't turn on.
KINDLY SUGGEST ?? :'( :'( Otherwise my dad go angry on me. PLEASE !!! PLEASE !!! PLEASE !!! PLEASE !!! SOMEONE SAVE ME _/\_

I just opened the back cover and disconnected the battery cable. I didn't remove the battery.
Anyway, you can search youtube for videos that shows you how to open the back cover.
Cheers!
Thanks for the help!!! had the same issue

Hey, i was in the same problem some weeks ago.
I finally figured it out after spending 2 nights continuously, so here is what you need to do.
1. Carefully open the back cover of your tablet and find the square connector which connects the battery and disconnect it.
2. Now download the stock Kitkat rom for the tablet from xda.
3. Install vcom drivers for mediatek 65xx.
4. While the connector is removed plug the cable to the computer or laptop.
5.Then connect the mini usb to your charging port (Again the connector should not be attached to motherboard).
6. Load scatter file in sp flash tool uncheck preloader, MBR and SEC_RO.
7.Then hit the start button and wait for it!
8. Now remove the cable, attach the battery connector to motherboard. AND BOOT!!!:good::good::victory:
If this help you please give a thanks.
Hi,
I've a Doogee S68 Pro that had a corrupt bootloader and crashed as soon as the Doogee welcome screen came up. I couldn't access the recovery boot loader so downloaded SP flash and started to format and download the firmware. This didn't go well and now the screen is black and doesn't show anything. When connected to my PC the phone keeps connecting and disconnecting all the time and the SP Flash doesn't download to it, presumably as the pc connects and disconnects...
Any one any ideas ?
UPDATE
Phone still has black screen and doesn't even show up when using platform tools adb devices.
When I plug the phone into a USB slot it shows up as a USB serial device or a DA VCOM device. SP Flash will start the DA side but comes up with an Error Hash Mismatch ?
I'm thinking this is now an expensive paper weight ?
