Somehow I have managed to brick my new cubot S550.
I wanted to update the rom so I headed to needarom and downloaded the appropriate rom and followed the instructions but somewhere along the line by pressing the vol keys and the power key the screen has gone black. This was done before I used any flash tools or install any drivers.
when I did plug it into the computer it was initially being seen as an unknown device but now I managed to install some drivers and it shows up as mediatek DA USB VCOM (android) (COM 5) I can install other drivers such as mediatek PreLoader USB VCOM Port and MTK USB Port and they seem to install but only after I untick show compatible hardware. When that is ticked then only mediatek DA USB VCOM shows in the list so I assume the state it is in is mediatek DA USB VCOM (android) (COM 5).
Unfortunately when I follow the instructions on needarom it throws up the error message S_COM_PORT_OPEN Fail(1013) so the flash tool obviously cannot communicate with the phone. This is the same even if I install the drivers as mediatek PreLoader USB VCOM.
The instructions on needarom are sort of wrong anyway because it instructs you to remove the battery etc but it is not a phone that has a removable battery.
I have two main questions.
How can I update the rom or failing that how can I get it off this black screen? I have tried different version of pressing the power button and vol keys and nothing is working.

Hi,
I had a quite similar problem. I tried to flash recovery with SP flash tool, but nothing happened. Eventually I gave up and tried to turn on the phone without success. So I charged the phone for a while and tried several combinations of holding power and volume up button for a while, also without success. It turned out that it did not charge at all. Strangely enough the following worked:
Connect the phone to a charger -> Press Power and Volume up -> Unplug charger while holding Power and Volume up
This launched the bootloader. After a few seconds it turned off again. But now I was able to charge the phone again and after a short while the regular charging icon appeared. Now I can boot it up as usual.
Hopefully it works for you as well!

Everything I've done as need sp flashtoolem, at the end of the show, a green check mark.
I disconnected the phone, try on and a button. Nothing responds to the charger, USB cable, or turning on Power.
After connecting the computer it does not detect it. Only when I press the volume down without batteries -It then begins installing drivers but every now and then connects to and disconnects the wilderness as a button hangs up pretty. On the Windows7 installs drivers and any Alcatel is device manager tab network adapters.
Under Windows XP, as the same thing I'll do is I choose the drivers and install mtk usb driver or something like that.If I hold the button volume down sees it but every now and then hangs up and connects. Turn on the SP flash rom going and what I did not press does not react, just as without battery and vol -, the program reacts goes red bar and pops up an error
bromine error s_ft_enable_dram_fail (4032)
I tried this rom with Jiayu Poland and pulled like Stocka F1WW-20140714-200639 -PC-update-foreign language

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:

Okay, i will try it first
Need help. I was using Miracle Box to flash stock ROM, I don't know how but the phone (Micromax E453) is bricked now. I tried to start phone in Meta Mode (swiched off phone connected to PC by holding volume up button), it worked once, then following some tutorials I uninstalled (and checked, Delete the driver software for this device) MTK USB COM driver under port. Since then phone is not turning on and PC is not recognizing the device. Tired changing the USB cable and even tried it on another laptop, but no go. Kindly share what else I can try. PC has Windows 10 64 bit and MTK preloader vcom driver always has yellow exclamation mark (always installs with error code 10). I have disabled driver signature verificiation.

Did you have USB debugging enabled in the device's system settings before it got bricked? If not, you might not get it to connect via USB and be recognized.

Thank you for your response. Yes, USB debugging was enabled before it got bricked. I was able to successfully see my device when I ran adb -devices command. I was also able to run fastboot commands. Now its completely dead.

Yes,it will not show up Qualcomm HS-USB QDLoader 9008 in device manager,seems to make no difference what drivers i download,seem convinced there is something not right with the phone.
That's right what it shows QDLOADER 9800 what phone you tmo or international\india version
Use different pc or laptop

I have the oneplus 8,i have tried a different pc,with the same results.Both pc's recognise the phone,and i can transfer files accross,it will just not show QDLOADER 9800 in device manager.
The phone must be completely shutdown before the cable is inserted.
1: power phone down
2: start your msm app and have it ready
3: hold both volume up and down at the same time and do not release
4: plug USB cable (that is already attached to the PC) into the phone
Your phone will not show any indication that it has powered but you should see it in the MSM tool as well as the device manager.

Have tried this countless times on two different pc's,it does not show up on msm or device manager.Also the when pressing and holding said buttons the phone will sometimes go into fastboot mode.
Try the following, power up your phone let it boot, if is finish with booting plug in your phone with the USB cable and look whether USB debugging is showing in status bar at the left bottom of the screen. If it shows USB debugging open CMD command window and type "adb reboot edl" and see what happens. Before you should start your msn tool that you can tap the enrum button maybe this works
Sorry,bottom of which screen
The phone shows in device manager when powered on and connect to the usb cable as " universal Serial Bus devices - IN2013,then when i try and go into edl mode the device manager does not see it's connected.
Only heard about it when I recently tried to unlock the bootloader of my device.
I'm trying to boot into it but my phone only shows fastboot and recovery mode.
It's now easy to bypass MediaTek's SP Flash Tool authentication
A group of developers has created a Python utility to bypass the authentication routine of MediaTek SP Flash Tool. Check it out now!

Bootrom is unbrickable tiny bootloader that is reachable usually with test point on PCB board or by pressing both volume keys while connecting usb to PC.
same for preloader mode, that is yet another bootloader but in emmc storage, and therefore flashable/brickable. preloader is reached without any keys pressed, just by plugin usb cable.
Note that device must powered off completely. When you see the charging icon on phone screen, it's already powered on (in charging mode). It works best with battery disconnected.
Both modes require VCOM drivers you should install quickly when device is connected and visible in windows device manager for a certain time.
