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.

Hello, I have problem with driver MediaTek DA USB VCOM. I have succesfuly instelled it. But when I plug my phone ZTE V970 in device manager it will show up for like half a sec then dissapear. So I cant flasg the phone since the SP flash tool cant see the path.
I also tried intall it via SD card. But when it goes to recovery (all in chinese) And I try to intall it by choosing the right ROM it will give the the answer that ROM file cannot be opened. The ROM is from XDA and in .7z format and I also found the .zip format. both didnt work.
I think if i can manage to tell my PC to see the driver then I can easily flash it. I am stuck on this step for few days already.
Also tried 2 another PCs and still didnt work.
I am runnig win7 64bit system.
Can someone please tell me where is the problem?
Thank you very much.
got the driver details
I managed in that half sec to click on the driver and look at the details. It gave me this:
Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer.
The driver name is: MediaTek PreLoader USB VCOM port (COM3)
Even after updating it and choosing the right driver (also from this forum).
When I turn phone up I will get that theres new device Android MT65xx and code 10.
I have exactly the same problem
I have exactly the same problem, how did you solve it eventually?
Anyone who can help ?

Please advise. Thx!
My MMX A110Q has gone on a bootloop. (I guess its hard bricked). I do not have usb debugging on
I tried reinstalling stock rom with SPFlash Tool but didnt work as the phone does not stay connected to pc for more than 2 seconds. Installed the drivers in my PC successfully. Now what should i do in this case. I used this tool "Mt657xRepartition_EN.apk". Which lead to this issue. Please do reply.
Thanks
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 !!!

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

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
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

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
I have a BIG problem with my Pixi 3 4.5 4G... I was trying to change the rom to the stock one, and I did it successfully, It never boot again It was stuck at the "COMPANY LOGO" so I star the whole process again, what happened is (This was very stup...) I click on the "Format Whole Flash" after that the phone is dead (just the led on the screen is working), I just use FlashTools to put the stock ROM again (so that means that Preloader was working fine at this point) and after the "Format Whole Flash" Im unable to get anymore the Preloader, and I try with a different Phone Just to check if the drivers was working and yes it is, so now I cant access on even recovery mode.
Note: The MTK USB PORT never change to PreLoader USB VCOM Port <Thats what Im looking.
same problem here!
Same problem :/
