Cannot connect my phone to pc

Whenever I connect my phone to the PC I'm not getting the connecting options..like whether to use the USB mode or MTP device etc. This issue started after I flashed JMP Xtream rom 3 months back. I told my problem to the service center but they are saying that they cannot help me.
I tried using my friends data cable but still no luck. But whenever I connect the phone its getting detected as an unrecognized device. I can charge the phone but cannot connect it. Also USB OTG is not getting detected even by using apps like stickmount and USB host controller..
Im irritated with the prob and require some help...any solutions for this prob..Im currently using Suvi v12 rom...

Phone is not getting detected at all when connected with cable...Its still coming as unrecognized device...
Wifi is the only option available or using the bluetooth connectivity option....
But there should have been an option to restore those connection options back...specially after flashing stock rom using CWM...

Download vcom drivers
It may help u

Try reverting to stock rom or flash some other custom rom as drivers are unable to serve.OR you can (after making a backup) wipe all your data.....restore factory settings on your fone as dis will remove any virus or faulty setting(some system paths nt shown in general).
HOPE IT MAY HELP YOU.

Tried installing VCOM drivers long back but still its getting detected as unrecognized device...
Also tried restoring through back up of stock rom v2 using cwm but still no luck
Just now tried by restoring to factory settings but no luck again....
Instead of installing drivers on comp..are there drivers for phone and all??

"Run "regedit"and select the "HKEY_LOCAL_MACHINE/SYSTEM/MountedDevices" folder. See all the "Dos Devices" listed? You'll have one entry for each physically mounted drive (HDD or Disc) plus you'll have one show up for each USB drive you attempt to insert. Double click each device listed and seeifyou seetextsaying something like"U.S.B.S.T.O.R...". Once you find that device, right click it and select "Rename". Now change the drive letter to something unused... like Q: or something. Close regedit, disconnect the USB device and reconnect again.
This will fix ur problem:thumbup:

try to connect your phone to a different USB port
or install drivers before you connect phone to PC(you can google for drivers)

[Resolved] [Q] I hard bricked Lenovo A536 Mediatek/ MT6582Mdevice

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

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

Why Can't I enter boot recovery?

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

But the SPD tool is not detecting my device. I haven't switched on the usb debugging, is it the reason? Now I can't turn it on too, because phone is not functional. Please help me again, thanxx.

SP flash tool can recognize your phone only if is turned off and if you have installed the USB vcom preloader driver

Have you installed the driver correctly?

Yes, i have installed the spreadtrum drivers. Do i need to install adb drivers for my phone also?

You need to install the USB VCOM preloader driver

Yeah.. I have installed those driver. USB VCOM preloader drivers are for mediatek, I have downloaded same drivers for spreadtrum. What may be the problem?

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?

Are you connecting the phone turned on or turned off, because SP-flash tool can recognize your phone only if is turned off

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

when i unplug the battery, it says unplugged, when i plug it back in, it again starts checking
Can it be a problem with my phone ???

OK... Maybe I have the solution now.
Follow this step:
1) Open SPD
2) Load the .pac firmware
3) Open the settings
4) Decrease the baudrate
5) FLash
