Hello,
when I want to set my MK808b in Flash Mode I do exactly like this:
o put the mk808 into flash mode the easy way:
1) Remove any SDcard you may have installed.
2) Connected the supplied USB cable from the device OTG port to your PC.
It will power up and windows may detect the device. DO not worry about that. We need it powered up.
3) In the ROM kit run the ROM FLash Tool.exe.
4) YOu should see at the bottom it says "Found RKAndroid Mass Storage USB"
If it does not say that go into settings and make sure that
a) USB storage is turned ON
b) Under developer options, USB debugging is turned off
5) Once it says "Found RKAndroid Mass Storage Usb" in the flash tool click the "Reboot to Flash Mode" button.
6) Wait up to at least 10 seconds. The unit should reboot and the screen for the mk808 will be black (no ouptut).
7) If the unit does not reboot to a blank screen, repeats steps above
Congrats! You are now in flash mode! To get out of it at any time just unplug the USB power to the mk808.
It will boot back up normally out of flash mode.
If reboot to flash mode does not work, then use this alternate proceedure.
In my ROM kit is another folder called alternate_reboot_to_flash_tool
This is the RKBatch tool. Run this tool and the 1 box should be pink.
If it is not pink again make sure:
a) USB storage is turned ON
b) Under developer options, USB debugging is turned off
Once you have a pink box, Click the "switch" button at the bottom and this should put it into flash mode.
Close this RKBtach tool now.

You have to set the USB computer connection to Mass Storage in the Rockchip Settings app (the icon with the yellow and white gear-wheel).
Here is a detailed video describing the whole flashing process:
http://www.youtube.com/watch?v=_mDFmP8sXNk&list=PL-x30K2aVGjfj-fyjvWm3-HsKfFJ6-y81&index=1
If it still doesn't work, try this:
Flash mode using the reset button:
If you do not ever see the flash tool say "Found RKAndroid MASS Storage USB"
Or reboot to flash mode does not work, then use this manual proceedure.
1) Have the USB cable unplugged.
2) Near the HDMI port are 2 holes in each corner. One is the blue LED hole.
The other in the corner is a reset button under the hole.
Use a paper clip or something to push the reset button in this hole.
I actually enlarged the hole so a paper clip would fit.
You will feel the button "click" when you are on it.
3) Hold this button down and while holding it, plug the USB cable from the PC to the OTG port on the mk808.
4) YOu should here windows BONG it found a new device. The LED will not light!
5) You are now in ROM flash mode. Read below for installing drivers.

Hi,
thanks for the answer.
I did exactly what is shown in the video. But all I get is recovery Menu (see attached Pic). Same with reset button method.
Any Idea?

That's strange. Are you sure the PC is connected through the OTG port and not the power port? (OTG is on the side, power is on the end). And are you sure you have a genuine MK808B? Because there are many clones around.

Yes its the OTG port on the side and yes its the MK808B. Ordered from Amazon.
Maybe its a new Version because it came with Android 4.2.2!?

Loaded Android on my HTC HD2. Had issues with android, so I went back to Windows. Used the following to load Android
SPL-2.08.HSPL
Radio that support 576 MB RAM
DFT MAGLDR Bootloader v1.13
ClockworkMod Recovery v1.3
Now want to load android ROM again, but USB port will not work when I power on phone holding down volume button. Goes into multi colored screen but I never get USB in the white field. USB works fine when phone is being charged. When plugged into USB port on computer when in Windows mobile, PC does not recognize phone. Searched forums and it seems like a lot of people are having this issue, but no one seems to have the solution to the problem. Was hoping someone could help with this. Thanks!
Are you sure you have Active Sync or Windows Mobile Device Center installed on your computer? You have to have the correct version of this to have the correct drivers on your computer.

Yes, I have WMDC installed. My bigger concern is why the connection will not change from serial to USB when I boot into the multi colored screen by holding down the volume button while powering on the phone. If I have the USB plugged in when I'm booting to the multi colored screen, it just displays a white screen where it should say serial or USB.

If I am understanding you correct if you have the USB plugged in when you boot to bootloader(multicolor screen) it only displays a white screen. Does it x the Sam thing if you boot to bootloader and then connect your USB cable? Also I reread your first post and I see you also say your computer does not recognize the device when you are booted into a Windows Mobile ROM and you plug the device in via USB. Now this is really not good as it might mean your micro USB port on the device nolonger is functioning for data transfer. I suggest you connect your device via USB and then go to Control Panel and open Device Manager and seecwhat your device is listed as there, post it back here in this thread too pleased. I have a feeling though that you are just having a driver issue.

If I boot to bootloader and and then connect USB cable, it stays on serial and never changes to USB. When I plug it into my computer, the light comes on to show it is charging, but the computer never sees it. Even if I scan for HW changes, it never sees the device. Windows doesn't make the sound it normally does when you plug a device in via USB.

I definitely think you are having a driver issue, try this if you do not have a Windows Mobile ROM on your device and see if you can do any kind of data transfer via USB. Try doing some file transfer on your SD card, if you can do this then yes you most definitely have a driver issue. I would then re install WMDC and then boot to bootloader and see if you get the USB in the in the white bar of bootloader that shows you have the HTC Sync connection.
Unable to do any kind of transfer via USB because PC does not see phone as being plugged in when I connect it to the USB. Storage on the phone does not show up under My Computer as additional storage when connected. Attempted to reinstall WMDC and it gives an error saying that it can not install the device drivers. You mentioned Windows Rom, phone is running Windows Mobile, if that is what you meant. Thanks!

Man in that case I hate to say it but it sounds like the two data pins in the micro USB have stopped working.
Have you tried another computer?
I have a broken screen and digitiser - I can see nothing at all on the screen and it does not recognise any touch movements.
The phone does appear to turn on and is recognised by my computer.
I want to retrieve all my data - photos, videos etc - from the internal SD card.
Unfortunately I did not have USB debugging enabled when the screen broke.
Is there a solution to achieve thiis?

Connect with usb and copy your files to the pc You don`t need usb for that.
Thanks for your reply Gee but that was, oddly enough, the first thing I tried.
The computer recognises the device as a portable media player and there are no files found in the device.

Maybe my original post wasn't too clear.
I need to retrieve all my data from the S4, and the conventional method of plugging in to my computer via USB does not recognise any data. Would I possibly have to select to mount the card to view? Either way, this is not an option due to the broken screen.
My next thought was to use ADB to transfer over all the content of the internal SD card, however, my S4 is not recognised using ADB (I assume as USB debugging was not enabled when my phone broke?)
So, is it possible to enable USB debugging without use of the screen on this device?

do you have custom recovery on your phone??
No, the phone is entirely stock.
I'm still holding out hope that someone has seen this happen before and knows of a solution for me to retrieve my data?

Can I flash customer recovery, though, as I can't see my screen?
You could install ClockworkMod Recovery and use ADB to retrieve your data while it's in recovery. You can put your phone in download mode by pressing and holding Volume Down, Home and Power buttons till it vibrates. Then press Volume Up to confirm that you want to enter download mode. You should then be able to use Odin to install ClockworkMod Recovery.

you can boot in download mode and flash it without screen. see if odin recognize it
In my opinion if u could turn on usb debugging that would not bring back your lost data. Not really sure though. You could do that by connecting a micro usb to hdmi cable to your tv and then i guess you could use the phone there, not sure if the touchscreen would work though but worth a try..

Thanks - I have flashed CWM via Odin successfully.
I have installed ADB but my device does not get recognised as an ADB device - have I missed something?

be sure that you boot in custom recovery, connect your phone, open cmd in adb folder (shift + right click) and type (no need to enable usb debug):
Code:
adb devices
you must see the serial number (in recovery mode)
Code:
adb pull /sdcard/
use attached adb folder

Because I can't see the phone I'm not sure the state it's in.
Is it just Volume-up + Home + Power to access customer recovery?
I can now see the device in ADB.
When I run the adb pull /sdcard/ command I get an
error: device unauthorised. Please check the confirmation dialog on your device.

hmmm do you read "recovery" in command line after the serial number?
there is a dialog box showed on your broken screen, try to tap on, maybe you will hit confirmation
EDIT: your digitizer is broken!......no way to recognize touch.....
I can't enter fastboot mode. I haven't done it before so maybe I am just doing it wrong, but all the instructions I found and all the threads I read don't help.
When I start the tablet pressing power + volume down I don't get the menu with the Wipe, the USB icon and Android. I end up in a menu with (from left to right) RCK, Android and Wipe.
Can somebody tell me what I am doing wrong?

You have a different bootloader version. Just start it up connect to the PC with adb running and it will automatically begin fastboot.

I tried that too, but when I then try "fastboot devices" I just get an empty line. Tried that on two windows and one linux machine. I also reinstalled the different drivers for the tf300t several times.
Fastboot is very sensitive to connection method. You shouldn't use any usb hub or keyboard dock. Also try different usb ports. And check port on tablet, may be it caused by slightly bended connector.

I tried different USB ports on 2 different notebooks...
And normal connection (MTP for example) is working fine.
How it presented in device manager? May be is limited access issue(e.g. on linux fastboot usable only with root access).

On device manager it is shown as Asus Android Bootloader Interface.
But I'll try with an admin account...
edit: Same with admin account.
I figured that it looks like a problem with the drivers (at least concerning Windows) and decided that updating Ubuntu to 13.10 might be worth a try (since I was planing to do that anyway).
And it worked. I have know idea what was wrong on Linux before, but now i get:
015d15b4d964120d fastboot
when I do "fastboot devices".
Looks good. Now I have to charge the pad since it is running low on battery from trying so hard
my nexus 6 will only charge no data transfer and pc wont recognize it. When i connect it to the pc it goes staright to charge mode and the usb trident symbol doesnt ever appear. In developer options usb configure is stuck in "charge mode" only. Ive tried different roms from pie to mm . i reinstalled bootloader and radio, tried twrp back ups and still the same. Had new charging port put in phone thinking that was the problem but didnt help. Ive searched google but couldnt find anything. Any Ideas, really appreciate it thx
When I installed stock rom which was android 7.1 it changed phone back to encrypted. Now i have to format internal drive in order to install a pie rom. Does anyone think that formatting internal drive might fix problem with not being able to do anything but charge phone from usb port, because if that doesnt fix it there would be no way for me to put any rom on my internal drive to install it.. Does anyone have any suggestions

Just to double check that adb devices shows your serial #. If not, it may be a driver issue.
Computer doesn’t see it, when I enter adb devices it doesn’t show up. Nothing shows up in device manager either: Also when I enter fast boot on the phone “power lower volume button” it says “connect usb data cable” I’ve trued numerous cables that work fine on my other phone. So it’s not the cable. After I plug them into phone it still says connect usb data cable.
I also have a thumb drive with a micro usb connecter that used to work on the phone. Now the phone doesn’t see it when you plug it in to the phone. But it works on my other phone so it’s not the thumb drive

It sounds like a driver problem. Is it a windows PC? Have you tried installing the Google USB driver? I've had similar issues, and reinstalling the driver(s) has worked for me.
It’s windows 10 and I reinstalled driver, other thing is in my car when I plug it in to the usb slot for android auto, it doesn’t show up in my car either and it used too.
It’s like the phone is stuck in charge only mode and I can’t get it out of that

When you connect your other phone to your PC, does its serial # show up in adb devices? If so, I'm out of suggestions.
1 more thing.. Have you enabled USB debugging in Developer Options?
Other phones shows up and in devolpers options in “usb configuration” you can set it to mtp but when you hit enter it goes back to charge only. I was on” aiop 14.0 rom” when it happened but it was working fine on that rom , then one day android auto kept saying connect usb, so when I got home I tried to plug it into pc and nothing. So I replaced charging port thinking that was problem but it didn’t help. Flashed other roms and even went back to stock, reflashed bootloader nothing helped. I was hoping someone here had seen this before cause I googled it and nothing like this could I find

Forget USB configuration for a minute. In developer options, under debugging, USB debugging needs to be enabled.
usb debugging is enable also. even tried turning it off and back on again, didnt help.
you know when you connect phone to pc and you normally see the usb trident symbol on your phone, well when i connect it to the pc i dont see that symbol it just goes straight to charging but even charging i should still see the usb symbol and i dont,
Hello All,
There seems to be a bug in OneUi 3.0 that prevents you from accessing the recovery menu through the usual way, Power Button + Vol Up.
Here is the solution:
1. Turn Off your phone
2. Wait 5 Seconds
3.Plug in your earphones to the Usb-c Port
4. Press Power Button + Vol Up .
There you go!
As an alternative to step 3 you can try using your charging cable, connected to your PC.
Good Luck
I plug USB memory stick in. USB A to USB C adapter we got in the package also works

You have to have either the headphones plugged in, or the usb cable plugged into the PC to access recovery and also download mode i think.
We knew this since beta 2 or 3..
