An EBL must be injected. None was found in the downloaded file.
For some systems there must be an injected EBL. The file specified for download does not contain an injected EBL.
Check that the file is correct for the target. This error can also occur on a normal boot time out, in which case just try again.

Can you please give me the driver link for CDC?

one port as "Android device" -> "android bootloader interface"
after i install the ADB installer from here http://forum.xda-developers.com/showthread.php?t=2588979
(the fastboot doesen't work for me...)
but the other 3 ports are ander the "Other Devices" and no driver...
Can you please give me the drivers for the rest. and explain?!

I will just stick with installing it as is then.
Folks, all I have done is:
1. Extract the finnish rom into a folder using winrar.
2. Copied MaUpgradeUt_NoID.exe into the folder.
3. Disabled USB in ActiveSync.
4. Run MaUpgradeUt_NoID.exe
5. Reset the iMate into Bootloader using Camera+Power buttons held with soft reset.
6. Connected the iMate with USB.
On the last stretch now so I will post results.

I still got the same problems. If i use the original MaUpgradeUt i get the "error 201: get device data error" and if i use the MaUpgradeUt_NoID i get the empty version thing. Can somebody please help me? I even tried to upgrade with the SD method but only found the spanish ROM on the xda-delveloper FTP with no results. If somebody nows where to find the ROM mda_compact_upd_en_1.zip from the nowicom.com page, could you please let me know?
I'm realy out of ideas so if somebody got any.........
is there a posibility that I killed my bootloader? if zo, can somebody please tell me if I can fix it?

SP Flash tool stuck

Hi, i tried to flash my bricked phone (Lenovo a7000-a) via my laptop with Windows 10. I installed drivers for mediatek, and in SP Flash tool set setting "Usb Checksum, Storage Checksum" to true. Then i insert scatter with stock ROM, and click to "Download" button.
Then i pressed VOL + button on phone and connected it to computer.
Then PC recognized "Mediatek USB Port" (on image *1*). After ca. 5 seconds this device disconnected. And after ca. 5 seconds connected "Unknown USB Device (Port Reset failed)" (on image *2*)
And here flashing stucks at "Download DA 100%" (on image *3*)

This isn't hard to find with a search for
"BROM error SP flashtool"
https://forum.hovatek.com/thread-439.html
Learn to use Google with simple search terms for exactly what you're looking for, as in my example above, you're using SP flashtool and you had an error, which is exactly what I searched for. You're almost guaranteed to find something. The link I gave you was the first thing listed at the top of my search results, my simple search took me straight to what you needed, it could not have been any easier than that.
That tells me that you didn't try to look, or you did look but didn't try very hard or didn't use your head when you looked.

[solved] adb not recognising phone in fastboot(download) mode

Hello All
I have had to reinstall stock(sm-g930f) due to an own stupid(again) mistake.
The OS is reinstalled and working and now I would like to flash Magisk through ADB. ADB recognises the phone by "adb devices" when in normal mode. When in fastboot (download mode) it does not recognise the phone. All it states is: List of devices attached
Can someone help me to overcome this, or if you have another suggestion to flash Magisk?
Edit:
after searching for a long time I read somewhere:
Do not put phone in download(fastboot) mode, only in charging mode when connected to the PC's motherboard USB port. Works flawless since, with having the relevant ADB drivers installed.
Adb is adb.
Fastboot is fastboot.
For adb, you need adb binaries.
For fastboot, you need fastboot binaries.
I have downloaded these and and haven't had any luck. Is there a detail how-to somewhere?

Probably because you didn't have drivers installed.
You need to find the specific drivers for your device model and install it.
Good luck.

Did you really try to find ?
Here is the download for samsung usb drivers: https://developer.samsung.com/mobile/android-usb-driver.html
Install it and reboot.
If it doesn't work, probably you have any problem in your device manager.
I'm an user linux and I hate windows.
Good luck google'ing it.
Im having the same problem. i don't want to use the adb setup thing becuase its a virus so yeah.

adb cant find 4g Adas Mirror, any help pls.

Hi!
This is my first post here, I hope I won't make many mistakes and troubles...
A friend of mine asked me to help him with his car Android based mirror.
The mirror is a "4G Adas Mirror" which is now stucked on the boot screen/logo.
Android version on the device is 8.1.
I've tried to reset through the hard reset button, without success.
I tried to connect the device on my PC to try to get access with adb, no success.
Adb cant see the device, the device list is empty.
When I check in the device manager on my PC I can see under "Portable Devices" installed,
with the name "MTP USB Device".
I also downloaded several drivers but can't install them, not for my device.
And now I'm out of ideas.
If somebody have any idea what could I still try to bring back the device into live, I would really appreciate.
Thank you.
Btw.:
My PC is running win10 x64 Pro
You're probably stuck with only the MTP interface (and not a composite device with MTP and ADB) but it might be worthwhile to double check.
Is the MTP interface active? Can you see any files in Windows File Explorer?
You can check with UsbView.exe to see if there is only one interface, the MTP.
The next step is to try various buttons on boot to see if you can get to recovery, fastboot or ROM bootloader.
Thanks for the fast replay, I cant access the device throug any file manager, as you mentioned, I checked with UsbView.exe already, just to be sure.
The MTP is active.
I've tried many many times the switch combination with the reset button, to try to get into any recovery or whatever cmd line mode, but without success.
The device hase only two buttons:
1. Power button
2. Reset button

Well, there's many ways to skin a cat.
If you open it up there could be a UART with a rooted hardware console.
There could be pushbuttons or test points to get into some other mode.
Good photos will tell us.
So, here we are....
the mirror crashed until I tried to open it.
However, if somebody is interested to hack and poke around this device, I'm familiar to open the device,
make schematics, pictures and try to hack into the device to try to make it alive again.
If somebody is willing to be a part to this pls. let me know and let's get started.
Open it up and take photos.
I'm trying and searching for a way how to open it but not fully crack the mirror, which is actually also a monitor...
I hope I will open the device soo and be back...

BV4900 Pro systemupdate and brick

Hello everybody!
Yesterday, on 28 of December, I had a massage on my BV4900 pro that a systemupdate is now ready to be installed.
After download of 2,48 GB file the installation went on, the phone started in the next step. On the screen was this white circle and the installation-progress was shown under. After the update was completted, the phone didnt start. The screen ist black. I cannot do anything with it. I tried to flash the firmware or at least the preloader with sp-flash-tool, but cannot. The connection to sp-flash-tool is with 100% but then I see under device-manager is "Media Tek PreLoader USB VCOM (Android)". So the flash-tool does not flash. I tried with volume buttons to stop the battery-loading, but withou sussess. What can I try more to save the phone?
Some more informations: The red LED ist on, when the phone ist connected to pc or power-supply. The phone was rooted. The last android version: 12
And maybe this picture will help:

Just a Hint:
Do not flash preloader! preloader is responsible for preloader mode (which used by SP Flash Tool)
Do not use "Format all + Download" option. Formatting whole emmc will brick device.
regarding your issue. follow the recommendations of your screenshot.

Yes, I did it already. Nothing helps.
I spend the second day with this problem and do not come forward.
you already tried another cable and another PC? then probably usb jack is faulty. you shouldn't flash anything via usb then!
I am not the one who told you - you could try other flash tools. do not flash, just try to read back for now...

Somebody else, who maybe has an idea?
I found this discription of the error:
The phone seems always be on. With power button I can only "restart" it. How can I shut it down?
Is there a tool I can use for switch the phone off?
Or maybe cmd-command for shutting down the device on com-port? I cannot find anything in internet. Only with adb. But I have no connection to adb, the phone is over adb not rearchable.
Maybe someone can show me the test point for this smartphone?
