Hi,
i recently gotten hold of an allwinner A31 device being the measy B4K. (http://www.measy.com.cn/product/showproduct75_en.htm)
I also gotten hold of a firmware update for this device from a guy that was in contact with measy support using a chinese friend:
http://www.freaktab.com/showthread....S918S-firmware&p=130534&viewfull=1#post130534
firmware rom download is here : https://alimail.alibaba.com/alimail...eb961&[email protected]
Now from what i've seen from other a31 devices is that you have to use the phoenixlivesuite to upload the firmware and you need usb debugging for this (the tool itselve says so also). but the device only has 2 female usb ports and no usb micro port not even on the PCB that i can see when i opend the box. One of the guys bought a normal male to male usb cable and tried in the diffrent usb slots but was not able to get any response. some others said that you need an usb otg cable but does that even exist for a usb male to male cable ? (if so where) if not would using a micro sd cable from my phone with a usb micro female to usb male adapter do the trick ?
also the img file is in some special format but it can be unpacked well almost all files using the tool from this thread http://forum.xda-developers.com/showthread.php?t=1753473 and it gives me all kind of *.fex files like uboot.fex, recovery.fex etc it only had problems with one fex file being sys_partition.fex but i did get a system.fex of 400mb.
i have root on the device also and i can get into recovery mode using a reboot to recovery apk however it's useless since i can't move around in it, the remote don't work, nor a keyboard attached to it and it has no physical buttons.
Anyway my main question is what sort of cable should i get to get this work a usb male to usb male or just some usb female to usb male adapter + usb micro phone cable to get usb debugging working so i can at least get windows to recognize the device.
I'm also posting this for other people since i don't think many people know about that firmware file for b4k, perhaps others having the same device have more luck
thanks

When you plug a USB thumbdrive to the phone, it first recognises the drive name but doesn't show any options to use it (even in file manager).
Maybe it's due to the connection type (MTP only)...
Any ideas?
Can you access your files in your USB thumbdrive using the file manager?
I'm using Astro Manager to access, and play my video files directly from the USB thumbdrive.
In fact, I just realised I can access if I keep pushing the cable to the phone... Maybe the cable connection isn't that good. I'll buy a new one.
New mission will be to enable wake using volume key which might be more difficult...
Thank you for your answer!
On my tablet , I use USB host ( full usb connection ) , which means I can plug in a pen drive , keyboard , mouse etc...
Can I do this on the Xperia S ???
With a micro usb adaptor I assume ??
Just found a Vid : The answer to my question is yes !

This will enable you to use USB on the go (OTG) feature that comes with Android 3.1 on our Jetstream. However, I for one don't think its truly on the go because you do need an external power source for it to work. But it allows me to connect my hard disk and work with it without the intervention of a computer which is more than great for me. But would surely like it if you could directly plug in a pen drive (not yet possible I think as far as I could search).
I have note made any of these, have just researched, tried a lot and managed to get it to work on my Jetstream and am just compiling the steps and methods I followed here.
Thanks to sztupy for his thread http://forum.xda-developers.com/showthread.php?t=1450298 for giving the basic idea.
Thanks to hellcat82 for his software NTFS Mount found at http://forum.xda-developers.com/showpost.php?p=13337600
Pre-requisites:
1. Must be rooted with Superuser and Busybox loaded
2. NTFS Mount software (use version 1.2 as 1.3 has some issues with Busybox as per the above mentioned thread and personal experience) - alternate is USB Mount by the same developer available on the Play store at https://play.google.com/store/apps/details?id=au.dach.drivemount (however I have not had success with it)
Hardware Requirements:
1. USB OTG Cable. Can be found at http://www.ebay.com/itm/Micro-USB-H...370670?pt=PDA_Accessories&hash=item3a731ccdae
Just a sample, costs around $ 2. I got mine from a local hardware store for Rs. 300 ($6)
2. USB Y cable. Can be found at http://www.ebay.com/itm/USB-2-0-Min...552?pt=LH_DefaultDomain_0&hash=item1e624b8dd0
Just a sample, costs around $ 2. I had one lying around at home.
3. USB Charger. Can be found at http://www.ebay.com/itm/Black-Plug-...er_MP3_Player_Accessories&hash=item1c254df23a
Just a sample, cousts again around $ 2. I got mine from a local hardware store for Rs. 170 ($3)
4. USB Hub (OPTIONAL) - this will enable you to connect more than 1 device at a time. If plan on using this, then you can get one with an external power source and skip the USB Charger.
Procedure:
1. 1st, after obtaining root, confirm that USB Host more is enabled on the Jetstream by checking the build.prop under /system using Root Explorer found towards the end of the screen. It should read as:
# support USB Host
rp.usb_host = 1
If not, then you must enable it by allowing R/W mode.
2. Next step would be to set up the hardware in the right manner. Note this must be done before connecting anything to the tablet.
The USB Y cable comes with 2 male USB ports and a single female USB port. The USB device to be connected must be attached to female port. The USB power charger must be attached to the side Male port and the USB OTG (micro USB to USB female) goes to the main Male port. With this all necessary connections are made. Refer to the attached picture (thanks to sztupy again) for details on other ways of connecting and using including with USB Hub (I personally have not tried the hub).
3. Put on the power source that is connected to the entire system and in case the external hard disk also uses one, that needs to be put on as well.
4. Lastly, connect the Micro USB cable with all the above connected to it to the tablet.
5. In order for the device to read/write or access the USB storage, next step depends on if the device is FAT32/NTFS
a) for FAT32 - you can go to the settings, storage and scroll down to USB storage. You will be able to see the details of the connected hardware and can click on Mount to mount and use. Unmount later to disconnet.
b) for NTFS - you must open NTFS Mount software. From the drop down list of devices, select a device (mine always shows sda1) and click on mount. Unmount from here itself later when done.
By following this, you would be able to access your USB external storage (pen drive/hard disk) with ease from your tablet directly.
Note: in order to access the files, you must use Root Explorer/Astro File Manager.
FAT32 device appear under USB folder of sdcard (i.e inbuilt memory)
NTFS devices appear under /mnt/sda1

1. usbhost_2.jpg - a diagram with the detailed setup (thanks to sztupy)
2. NTFSMount1_2.apk - NTFS Mount (thanks to hellcat82)
Hope this helps.
Is it truly necessary to have the OTG usb cable? I currently have a powered hub. Shouldn't I be able to use the provided JetStream usb cable and tie the devices together through the hub?

Hi, sorry for delay, was out for an exam.
I don't know if or not it will work. As I said I have just researched and seen what others have implemented and put it together.
Perhaps you could try and let us all know because I don't have a USB Hub (powered or otherwise) and hence have not tried it out.
This all seems a little much for OTG support considering it was just plug and play with my SGS2 and also my SGS4G. I am hoping to see some more development in this area as this type of support is nice to have on a tablet of this caliber.

Hello,
I have flashed cm7 and recently i have noticed that my USB port does not work! . I searched in play store for stickmount but it says that my device is not combatible with this version. When i try to download it from other external sites it says there was an error parsing the package. Is there any solution to make my USB work?
USB is working.
What are you trying to do?
Attach an USB Stick?
Are you sure that the OTG cable you are using is OK?
are u talking bout the usb host or the mini usb port to connect to pc, eyther way for me only the host works, but that isnt such a big problem for me except the fact that i cant connect to pc?
I am trying to attach a usb stick directly but the archos does not recognise the usb.
AGAIN, and you are using an OTG Adapter?
No i am not using an OTG cable. I am trying to connect it directly through the usb port.
Are we talking about a A70 or an A101?
A70 NEEDS OTG.
A101 is known for "blowing" the usb-port. That was fixed in the last FW ( 2.3.84 and UD 1.6.4 ) but not in CM7.
I have an archos101. What is FW 2.3.84 and UD 1.6.4 . Are they more stable roms than the cm7?
FW == Archos Firmware
UD == UrukDroid
I can't ( don't want to ) tell you what's better for you, you have to search for your self in this forum, there are tons of infos about that.
I know! Thank you!
Hi,
does any of the countless i9100 (not "G") ROMs have OTG support?
Best regards,
toshibashi
CyanogenMod does support OTG.
Just checked with CM12.1.
And when i remember correctly, Cm11 worked as well.
I have cyanogenmod 12.1-20160106 Nightly-i9100 kernel 3.064-cm-gd71763e [email protected] #1. I have enable Android debug brigde and usb debbuging but OTG is not working. The cable is tested on a sony experia tablet and works fine with usb mouse and usb flash drive. I have also download several programs like USB OTG Helper, Stick (something), and others i don't remember. One of them said s3c usb host driver is missing. Any idea how to fix OTG?
Thanks in advance
What is OTG?

OTG is the ability of a phone to connect USB devices with an adapter connected to the microUSB port. You can connect keyboards or USB sticks, for example.
Well I run stock CM12.1 and never had any problem with OTG. I don't know if it might be the problem that your USB OTG adapter is not from Samsung?

You will need to include this in android kernel and then flash that kernel. First learn how to compile kernel, then learn adding additional drivers and then compile your own kernel.
