[Q] MTK 6589 VCOM - LPT COM port issues - Android Q&A, Help & Troubleshooting

Hello to all,
Everything went wrong on flashing with SP Flash tool. The Preloader of Scattered file was checked and all others.
The problem is strange for me and I see that there are other with the same issue without an answer.
Fist of all I did everything described in forums. The driver of MT Preloader Vcom port is installed correctly. In Device Manager LTP com port is detected and as it is normal it disconnects in 2-5 seconds. If I change the USB port on PC it changes the COM port which is the previous detected.
The issue is that my latest SP Flash Tool 5.14 or even 3.13 older one, can't establish permanent connection with the COM port of the MTK 6589. I tested with different cables and different OS (XP and Windows 7 32 bit) on different computers with first pressing Download button of SP Flash Tool and then plugging the cable. If I don't press Volume Down button of my Huawei Ascend G610s it can't be dected of SP Flash. After pressing Volume Down the enters into Meta mode BUT .... SP Flash Tool report:
BROM ERROR : S_BROM_DOWNLOAD_DA_FAIL (2004)
[H/W] Fail to download DA to baseband chip's internal SRAM
[HINT]: 1. There's an cable communication problem between FlashTool and BootROM.
2. Target might be shutdown unexpectedly or target lost power supply.
[ACTION]
1. Try again.
2. Proceed H/W checking in download cable and target side com port.
3. Monitor if power-drop occured in target side.
At some reason COM port is constantly disconnecting and connecting without establishing permanent connection with SP Flash Tool. The red bar pops up and shows 100% done.
Any idea for this issue? You will help a lot of people which don't have the answer what to do.
Best Regards

I have the same problem please help

Hi ...what is the phone model?
In my case the issue was solved with a hardware "kick" with button combination because at some reason the MTK preloader was put the phone in nonsense turning on and off the without being able to establish permanent connection. I tried all the MTK drivers but the issue was some kind of bug which actually was constant switching off. My model phone was Huawei G610s. What I did was to hold Power, +, - button together for about 5 seconds then release power still holding + and - button, and after 4-5 seconds release + button while holding - button for 4 seconds. This kicked out from the constant disconnection and SP flash tool was able to finalize the flash. Without this every time the error was as your have described.

SP Flash Tool works through preloader. Usually when you power up your phone, preloader kicks in first and sets up it's own device on USB port. You have a split second to start talking to it, otherwise it will load the next part of software, which will set up another device on the port.
What do you have to do:
Double-check your USB cable! Cable problems can lead to weird errors in SPF tool.
Shut down your phone completely, remove/insert the battery after it to be 100% sure that the phone is shut down.
Set up SPF Tool, hit download button
Connect your phone to PC via USB cable
At this step, your phone should power up, but if it doesn't in reasonable time (say, 10 seconds), press the power button to switch it on
If everything done right, the following happens:
Your PC finds "mediatek preloader" device or something similar
Red progress bar starts running in SPF tool, it means DL helper firmware is being transferred to the phone
Blue (or green) progress bar starts running, indicating your data being downloaded
A window with green circle appears, your data has been uploaded successfully

Bluboo s1 SP flash help pretty please

Hello.
Everything has gone terribly wrong for my phone and I desperately need your help.
I downloaded what was stated on needrom.com I made sure MTK vcom was installed properly and had the correct rom from needrom.com but I still got Brom Error: STATUS_BROM_CMD_SEND_DA_FAIL in SP flash when using MTK_AllInOne_da.bin.
I then tried DA_PL.bin and got another error. I tried to uncheck preloader and run Download through SP flash with DA_PL.bin which worked just fine. However now I'm stuck at the Bluboo logo screen and phone does not load into android.
I still get Brom Error: STATUS_BROM_CMD_SEND_DA_FAIL in SP Flash if I use MTK_AllInOne_da.bin but if I use DA_PL.bin now I get this error:
Chip mismatch!
Scatter:MT6757D
device: MT6757
Please help me, my phone is bricked until one of you help me. I'd be forever grateful!

Don`t worry about that, first this is the link of the last update https://www.google.com/url?q=https:...ds-cse&usg=AFQjCNFJKeEcDClPU2MnxLJefaQ19GmQpQ
for more success put your folder of SPFlash Tool near to folder of your unpacked rom (for short transmission of data) and Bluboo S1 has a few different way to enter to other mtk cause battery it`s not removable like other just disconnect it and connect again; in this case connect cable usb to your device, prepare all the files in SPFlashTool and click download and now while pressing both volume + and - connect cord to pc till SPFlashTool begin to recognize files (red letters) and release now, SPFlashTool continues process till 100% in yellow progressing line

Thanks!!! It works!!!!
Just be very careful. The USB C connector port in the phone is very loose... so make sure you can hold the cable tight other wiser it will lose the connection and brick your phone. For me, I had to remove the Plastic cover to be able to hold the power cable tight!
Hi, could you help me please? I did your steps, but it is not working. Sp flash does all its job, shows the green sign, but the phone stills dead. What I noticed the usb connects with the phone, then it disconnects. I tried to install the drivers as the tutorials say like deactivating the driver signature enforcement, but nothig happens well.

Hello. Got a problem with an MT6737M device - Anyone help?

Hi... I'm trying to be as concise and as detailed as possible here:
OK.. I'm trying to flash this ulefone S8 Pro with the STOCK ROM from the ulefone website. I'm using Debian Linux and the SP Flash Tool 5.1804.00 for Linux. I've disabled modemmanager (no conflict there) and I'm able to see from the logs that the device is recognised.
The device itself had it's stock boot.img flashed with a patched version (MagiskManager)and the boot loader has been unlocked - and all was working fine... someone decided to mess about deleting files from /system and the phone refused to boot.
So.... I took the device back and flashed boot, recovery and cache from the stock image using fastboot - all fine... then when it came to system.img - I found out that system-sign.img from the stock ROM wouldn't flash via fastboot - I got an error saying something along the lines of:
Code:
"Invalid sparse file format at header magi error: write_sparse_skip_chunk: ([I]I forget the size[/I]) is not a multiple of the block size 4096"
So, after a bit of googling - I was going to try the SparseConverter tool.. but this seemed to not like the system-sign.img and so I gave up on that idea..
Then I realize I probably need to be using the SP Flash tool - so.. I boot back into Linux and here's what happens.. When the phone is turned on.. I can hold power on + volume up to get the little menu (flashboot, recovery or normal boot) and it ignores this... it goes right to Recovery with "NO COMMAND" - no combination of button pushing does a thing... it will sit at no command, occasionally flashing the screen. When i plug it in.. and don't touch it.. same thing.. straight to no command.. when I turn it on (not plugged in) it does the same thing... when connecting to PC and SP Flash... I hit DOWNLOAD in SP FLASH and then with phone off (battery in) I connect it to the the PC and i get the red bar to 100% and then:
Code:

I've tried all USB ports. Various cables etc etc.. I've tried connecting with phone off and no battery (same thing - same output) - with the battery, without battery and putting battery in after connecting.. taking battery out and putting back in, pushing volume buttons on connecting USB... i've done it all.. same error all the time...
I'm almost to the point where I throw in the towel here... but I thought someone might have some clue or idea what to do now.
Any help appreciated.
Oh yeah.. lastly... dmesg | grep usb gives the following
Code:
[13640.521933] usb 1-2: New USB device found, idVendor=0e8d, idProduct=2000
[13640.521940] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0

[email protected]:~/Downloads$
found out how to unbrick!
OK!! SO... After a LOT of messing about I finally figured this out. What I did was start SP FLASH TOOL and put it in DOWNLOAD mode and then hit the DOWNLOAD button. I then connected the USB lead to my phone but NOT the PC (with the battery in the phone and the phone powered off) THEN I held down the volume up and volume down buttons together and kept holding them... I plugged the USB into the PC and kept holding the volume buttons... lo and behold it worked. I was too scared to let go of the volume buttons, so I just held them until the process had completed.
Hold volume down button when you plug usb lead in and hold until it starts flashing rom!
Also to enter recovery menu, press power + volume up when the command not found message appears.

MT6580 Powers Up While Flashing

I Have A MT6580 Chinese Device. Trying To Flash The Stock Firmware Using SPFT And/Or Miracle Thunder. But Everytime I Try To Flash And Connect The USB, SPFT Detects The Device But After A Few Seconds The Device Shows Charging And SPFT Says BROM Download Fail. And Recommends To Check The Power Supply And USB Cable. But Both The USB And Power Supply Are Fine As The Phone Boots Up Properly And I Have Used The Same Cable To Flash My Other Phones. So Could It Be A Hardware Related Issue Or Software Related? Any Idea On Fixing It?

Unable to connect Infinix x690B with Maui Meta tool for IMEI restoration

I did use Maui Meta tool in the past to restore IMEIs on slitely older MTK devices, but My current phone is based on MTK6768 with secure boot, needed the IMEIs to be written after flashing firmware. I can use SP flash tool with "sec boot" utility to flash ROM successfully, But unable to connect to Maui Meta tool. I have Modem meta tool Version 10.2044, after launching the program as an admin, it is doing the following:
1. Clicking "connect" and plugging the cable to phone in turned off state: windows make a hardware connect sound, a new port appear in device manager, followed by a disconnect sound after 1 second, that hardware disappear and phone boot-up in offline charging mode or to the welcome/lock screen. The "meta tool" remain at looking for device connection.
2. Holding the Volume down while plugging the Cable in, do the exact same - "meta Tool" remain in waiting for connection.
3. Holding Volume Up: it connect, then disconnect and went to Stock recovery - "meta tool" remain in waiting state.
4. Holding Power+Volume up: Windows continue making connect and disconnect sounds again and again and the Port under device manager keep coming in and out. Phone boots up as soon as I leave the buttons. "meta Tool" remain in waiting for connection, or sometime move to "getting Kernel Port" and get stuck at it.
5. Holding both volume buttons: do the exact same as point Number 4 above.
6. Holding both volumes+power buttons: do the exact same as point number 4 above.
Definitely, all MTK drivers are installed and working because I can use SP flash tool in conjunction with secBoot utility without any problem. I tried other similar tools like “SN writer” and “read and write tool v1.3” and faced almost same behaviour. It means my device is not going into Meta mode properly with these tools. Please contribute in helping me with your valuable suggestion, as I’m not being able to use this device due to cellular network unavailability.
You need to use Preloader Mode not MTK mode, look at Com Port driver, try boot device to normal mode and make power off then hold up and connect USB must get preloader device if get mtk USB port only not work, see mtk preloader to enter META mode

I have this same issue where my device can't get detected by any IMEI writer as itneeds to be in meta mode. Do you have any success on this ?

I also got the same Issue, But it gives a kernel error, Idk, what error it is, and what's the fix, The Local Tech Repair shop did the restoration, but gave me the mobile without IMEI, so, I am stuck, I am also afraid to re flash the stock rom, because I dont know what the hell they did, Maybe they did some kernel change, or the kernel is the same as the wrong one? Idk, Maybe I would say, Reflash your mobile, and check it.
Having the same-ish issue on redmi note 8 pro. any progress?
