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 !!!

Did you try to connect it to another PC? Because from what I can understand, it's a driver problem.
Today I also unlocked my bootloader to try Kit-Kat and I had a massive problem with drivers. Thankfully I solved it by installing the universal driver pack by Doomlord.

i was also facing the same problem try it in windows 8 and connect your phone after hitting the download firmware button. it will detect your phone.
Recently i tried flashing cwm recovery using sp flash tools. I followed an online tutorial which asked me to specifically download the boot. Img (patched) and recovery. Img, which was cwm. I insatlled all the drivers as asked then I turned off my device as asked and connected the device using usb cable after pressing the download button on sp flash tools. After a few seconds i saw the red line which is the starting of the flashing process, and then i received an error 'b_rom error" or something like that... I forgot, i dont have screenshot .
The phone is not responding since then, but when i connect the phone to my laptop the phone is recognised as 'mediatek da com port' but this driver doesnt work if i want to flash the stock rom using the sp flash tools, the internet says that i need the 'mediatek preloader driver' which is supposed to appear for 2 seconds in the device manager section and dissapear, but alas this doesnt appear in my case, and i guess this is really important for flashing the stock rom using sp flash tools. I tried many ways to install the mtk preloader driver but even of it installs it is not compatible with my device. I cant find this driver and hence i cant bring my phone back from the dead
If any member could help me here i would be really thankful , i have the stock rom downloaded and all the drivers as asked in various tutorials so i am helpless now. Please someone respond to this thread...
My device is xolo 8x 1000i with mediatek 6592 octacore chip.
Thankx ahead

If you can see DA VCOM port when u connect the phone that means there is no need of mtk preloader to appear. You can try flashing the stock firmware.
If you really want to see mtk preloader 65xx, then right click on DA vcom port and click uninstall drivers. Then you will see mtk preloader 65xx for 2 seconds everytime you connect the phone.

My phone is xolo era. I rooted it 2 days ago, I also changed the startup animation after rooting, then i thought about having on screen buttons, although i have capacitive physical button of my phone, but still. I tried to get on screen buttons by an app called pimp my rom, after switching on-screen buttons, it asked for a restart, which i did. But after that, when i switch my phone on, just after that it says unfortunately, com.google.androidui has stopped working, when I press ok, it comes again, keeps on coming continuously. I also tried to boot into recovery mode, but xolo sign comes up, again screen becomes black, again xolo sign, again black...............
How can I get my phone into recovery or change the rom by computer?
Please help me.
Maybe this can save your phone

Check if the manufacturer of your phone provides a tool like Odin, if not you can only use SP-flash tool.

Nope, nothing like this available. I dont think there is any other way to flash this. Just tell me how can i get to boot recovery. I tried 10000 times by using those buttons but nothing happened. Any other way to boot into recovery?

Turned off, I am even pressing the volume down key while connecting to usb so that it doesnt start charging.
It even recognizes my device, but gets stuck at checking baudrate
When it says checking baudrate try to unplug your battery and then replug-in

OK... Maybe I have the solution now.
Follow this step:

3) Open the settings
4) Decrease the baudrate

What did you flash exactly? You sure you flashed something that's specifically made for your phone ?
Also what combination have you tried yet.
Download another stock rom for your phone load scatter text ,click download and connect your phone to PC via USB while holding the vol+button only

Meta mode( usually vol+ button) is the most successful way of of recovering from a hardbrick for lenovo but after looking up your device you guys coonect meta mode dffrntly.now this is the most successful way of unbricking your phone
pick the official ROM for A850i came with A850_203 multilanguage firmware.
You'll need MTK 65XX metamode driver – USB VCOM Preloader driver, if you previously installed then there is no need.
SP Flash Tool to download the firmware to the phone.
(Make sure you have a working version as some so tool don't work as they're supposed to into ,I'm using version 5.1)
Run SP-Flash Tool, map the scatter loading MTK6582 for your firmware, normally inside the firmware folder. It will mapped the necessary file and partition for your device, After that click Download and leave it searching for device, it will start flash when found the device,
so next we need to activate back the dead phone of Meta mode USB Vcom MTK65xx , firstly remove the battery, simply press and hold VOLUME UP & DOWN + Power Button simultaneously while reinsert USB that connect the phone to PC.
The previous SP Flash that searching for device will start the download process just after the META mode activated, if you failed then try repeat the step :fingers-crossed:
And hit the thumps up button if this post has been helpfull good luck:good:
