UMS - USB Mass Storage on Axon 7? - ZTE Axon 7 Questions & Answers

Hello all,
It seems the Axon 7 only has MTP for transferring files to and from your pc.
Is there anyway to activate UMS for this phone?
Googling shows mixed results that are device specific.
Hoping someone knows how to find out... Or maybe we need a custom kernel for this... :/

That's kind of a bummer because my car doesn't really like MTP. It only seems to recognize any audio files like 1/4 the time.

MTP is a terrible protocol in practice (nice in theory), but that's what Google went with. The problem with UMS is that the phone has to unmount and give up control, and then the client device has to mount and unmount cleanly. During that time, the phone can't access the storage at all, and there is the potential for things to be unmounted cleanly. Which was a huge problem for the average person when you used to use the SD card to store apps and such, because they would suddenly be unavailable and people would wonder why.
Under MTP, the phone never gives up control of the storage, so you don't have to worry about any of that. It just stinks that it has so many issues and is so slow.

I thought it had something to do with the filesystem used as well, since it's likely that the sdcard partition is formatted as ext4 or f2fs, which are not universally-supported.

Double Memory Mount - Compatibility Issue

Ok so we have a incredible here in the office and the user is kinda let down about compatibility with music devices. And just wanted to make anyone aware of the issue for consideration.
He went from his iPhone to Droid and was able to mount phones in the Cadillac system. You can hook up and USB 1TB drive the whole nine very compatible.
The problem that lies with the incredible is that it mounts two cards at once.
The paths:
/sdcard
/emmc
This causes most devices to freak out except a computer OS and to top it off developers apps are bug-in out and having storage issues which you can find on an android thread from google.
just some food for thought
Yeah, I've experienced this...many apps that save to SD get cranky when trying to save on the Incredible (due to being internal RAM). I talked to a couple of developers...apparently there's no method available in the SDK to write to internal memory yet.
So head over to newegg\bestbuy\amazon and pick up your 32GB SD card

USB Mass storage problems?

Hey all, apologies if this is already covered somewhere.
I got my Vibrant a few days ago and promptly rooted it to get wifi tether. USB storage mode worked fine at that point and I was able to transfer files to the internal storage from a Windows 7 64-bit box.
Yesterday, I went to use USB storage mode on my Mac, and... nadda. I plugged the phone into my netbook (running Ubuntu) and both internal and external filesystems were available there, so it seemed like a Mac specific issue. I googled around and enabling USB debugging fixes this particular issue in OS X, so I enabled that.
The problem is, now the Win7 64 box can't access internal storage at all, regardless of the USB debugging setting! With USB debugging on, neither storage device is visible at all. With it off, both devices show up as "drives," but only the external card is really accessible from Explorer (the internal storage maps to "G" or something, and attempting to access it results in Explorer hanging).
So here's my question: is there any way to get this sorted out so that I can mount both devices from both of these systems? Normally I wouldn't much care about the loss of Windows support (since I mainly use Linux and OS X), but I just ordered a Galaxy S for my wife, and this is just not going to be acceptable for her.

Problems with MTP and USB access

hi, this has been bugging me for quite some time now eversince i've got my xplay. it seems that there are times that i'm unable to access my storage properly via MTP or storage device. it charges the phone and i can see the device on my device manager but nothing comes up in accessing the contents. my only solution is either by luck, with plugging and unplugging the unit or uninstalling the driver so it could detect it again but sometimes recquires me to restart my pc. my last resort is to unmount the sd card and go through a usb adaptor.
Got the same problem
No idea what causes it.
Also got random replugs where the pc thinks it's newly connected, rather annoying when watching a movie on the pc.
can anyone provide a probable cause for this or any solutions perhaps?
After it got really bad (rebooting phone not working and all several times) I uninstalled com.sonyericson.usbux
You can't acces your SD card anymore but atleast you can charge and push-pull things over adb.
my phone still has the stock kernel and i haven't rooted it yet. though there are still times that i can't access my mem card.
MTP wont work at all for me so I cant update firmware
MTP is far more picky and problematic than a logical drive. I run into data transfer issues with the Iconia A500 due to this, but zero problems with my gTablet that sees the internal space as a logical drive.
Wait a sec- The microsd is seen by the Sony firmware as MTP? That seems odd, since I am not aware of other OEMs that map microsd that way.

[Q] Seeing cards on PC

So I noticed that my sd card didn't want to show up on my PC. Or one of them at least. It turned out that the one I could see on my PC was the emmc card, and not the external. It wasn't too big a deal really. As I was fooling around, I installed a new driver (as part of installing theADB/SDK stuff) and then all of a sudden, the cards were reversed. I could see my external card, but not the emmc card. At one point, I swear i could access both cards on my PC. What can I do to remedy this situation so I can access both cards?

Tell us more. What version of software are you running? Stock, CM7, CM9, CM10 or something else? What version of software on PC? Windows, Linux, Mac? Do two drives show up but only one displays anything? Or just one drive? Are they drive letters or under other devices? And you are talking about plugging the USB cable in, not putting chip in card reader?
Thanks. Sorry for the lack of info. I am running CM7.2, and looking for the sd cards through windows 7. Honestly, I am not sure I have this same problem on my home laptop, but definately on my work laptop. Both drives show up, usually as E: and F:, but when I click one of them, it says "please insert disk into removeable disk f:"
Does that help?

Yes that helps. The problem is you are not activating the USB connection. You need to pull up the notification area and you will see a selection for turning on computer access. Until you do that the drives are not active on the PC.
Another way to do it is to use the app NookColorUMS. You can get it on my tips thread linked in my signature. See item B7 in my second post of that thread. That app lets you select whatever partition you want to populate the drives on the PC.

[Q] Hard Drives & MicroSD

1. What format does the drive need to be to be read by the MOJO?
At the time of this writing: Hard drives need to be NTSC. They are mounted as READ ONLY, so you will not be able to save files. Bummer.
2. Same question, except for a 64GB MicroSDXC format...?
At the time of this writing: microSD must be formatted as FAT32 with 32K cluster size. They need to be set as a PRIMARY drive rather than LOGICAL.
1. NTFS or FAT32 usb 2.0 HDs work. I've tried USB 3.0 HDs and so far those haven't worked
2. I havn't tested a 64gig micro sd but most Android devices only recognize up to 32GB sd cards.
I've got a 64GB in my A700 and it works fine as FAT32. The CM ROMS have issue with it, however. Also, according to the MadCatz website: "For those of you who need more, there’s a microSD flash slot to accommodate SDXC cards up to 128GB!"
What format is your MicroSD?

I'm using a 64gb micro sd, format FAT. Works great.
Try exFat. It's the "standard" format for SDXC type cards and unlike Fat32 you're not limited to files less than 4 gigs in size. It's the format i use on my Galaxy Note 10.1 (last year's model). It should come in exFat anyway.
Or the simplest solution would be to rip open the packaging, stick it in the MOJO and if it tells you it needs to be formatted format it. That way it's in whatever format the MOJO prefers and your pc/laptop in all likelihood will recognise the format.
Also I'm guessing you're just going to leave it in there most of the time. To avoid card readers and sync cables I normally use FTPServer on my phone and tablet and the filezilla client on the pc, and to transfer stuff to the network drive I use the android ftp client andftp (there are file explorers like ES Explorer which can handle samba connections and FTP connections but I find they're a bit slower).
Avoid NTFS on flash media. From what I've been told it uses too many read/writes which isbad for flash media due to their limited write cycles.
Yeah, I didn't even think about formatting until after I had loaded my card down with movies and music and games....exFat = Nope.
Found this: http://forum.xda-developers.com/showpost.php?p=48943761&postcount=5
FAT32.
Time to backup and reformat.

No ExFat support? Wow. Mad Catz put NO effort into the software of this device, did they. Just using the stock OS without bothering to add in bluetooth 4.0 support and just throwing in a dongle to compensate (various phone providers, i.e. HTC have a history of providing a better than stock bluetooth stack), no camera support, no exFat support (this just makes them cheapskates since they just needed to license it crom Microsoft like the phone makers that provide it on their phones and tablets).
I still have time to decide. I was planning on buying it on amazon, sending it to a friend and then having them bring it when they visited in order to avoid the overpriced shipping and import fees but I'm starting to think I'd be better off with a cheap quadcore A15 device with an SoC like the A80 from allwinner and a Moga controller. It would be cheaper, have better play store support and be more versatile from what I'm reading on here...
Considering how little effort they've put into the software I wouldn't be surprised if they never got around to the KitKat upgrade. Companies who put more effort into the OS often fail whdn it comes to promised upgrades. And if Mad Catz never upgrades the OS it means users are limited to just ONE USB port which seriously cuts dow on usability.
Wait, are you saying you can only use one usb port at a time because of the OS version?

yes beacause if there's no update to kitkat the BT smart dongle is in one already and will have to stay there.
I think it will come out, they have said it would a few times now. so just a matter of when.
yip I tested mine, no exFat support... a bit of a shame
Buy an USB Hub.
You can use hdd with ntfs should be much better then exfat.

At this time- the controller requires a dongle which takes up one of the usb slots.
You are left with the micro SD slot and the usb 3.0 slot.
When the Kitkat update arrives, you will be able to remove the dongle and have the usb 2.0 slot available.
The usb's will probably be obsolete soon anyway- seeing as PC streaming is coming in the kitkat update.
The point of mojo is to do everything via bluetooth and wifi.
That's the beauty of the machine.

Why use a usb to transfer data when you can pull data/stream data from your pc?

First of all, the point is that you're not getting the functionality promised. You are told that it's a micro-console with TWO usb ports and you can either give up the controller, or give up a usb port. Secondly a usb hub can be an okay solution but you then have to worry about getting a normal one or a powered one and how much it will affect throughput splitting it up depending on what devices you have attached. And as is others here have reported problems in using both USB drives simultaneously (and that some drives work better in one than the other).
Yes, streaming is good, you can actually use it right now if you´re just talking about transferring files, but if you're told you'll get two USB ports you should GET two functional and available usb ports.
KitKat upgrade. They've mentioned it, but don't think there's actually an official announcement. Plus they could have had that functionality there since the beginning. Smartphone and tablet makers add/take away functionality from Android and its Kernel. Heck, people HERE do it all the time. So why can't Mad Catz. And how long exactly do people have to wait for the upgrade? As the saying goes, buy a device for what it can do today, not what it can do tomorrow. Manufacturers often don't come through on promised upgrades.
Also to say that you/they support SDXC without a disclaimer saying that you can't use exFat is fraudulent as exFat is STANDARD on SDXC. If they made all this clear from the beginning it wouldn't be so bad but they don't and as such mislead their (potential) clients. Who cares about friendly and speedy support if they can't actually solve the issues present?
I would use the USB to hold a thumb drive full of data like the ISOs I've ripped from my GameCube and PSX for emulation. (Trying to get my wife to give up the Wii to our son when the Android port of Dolphin reaches maturity).
Formatted my card as FAT32, loaded it down, NO LUCK.
Tried the card in two computers and it shows up as FAT32 with all files intact. I'm on my A700 right now, popped it in, and it is working just fine.
There really needs to be a reboot option on the MOJO...Yes, I rebooted..no luck. Causes FC from settings when I try to see my storage.
Thoughts?

When you put the USB in, do you see it say, preparing USB in the top left?
You then have to go to your mojo settings, storage, and 'mount USB'.
It will. Then show up.
To unmount, go to settings, storage, unmount.
Working now?

Nothing.
When it was formatted as exFAT, I could at least get to the storage options...just wouldn't mount.
I'm trying an extHD to connect.
First try 1 partition 1TB NTFS - recognized and mounted without problems on USB 3.0 port. (but NTFS don't work on my LG G2)
2nd try 4 partitions 1,2,3,4, extFat 256GB recognized, but can't mount. (but works fine on LG G2)
3rd try 4 partitions 1 NTFS, 2,3 extFat and 4 NTFS - don't work
4rd try 1 partition 1TB extFat - can't mount.
So, I let this thing NTFS formatted now. :silly:
If the M.O.J.O could be rooted, we could use tools to mount ALL formats and ALL partitions.
Solution for my rooted LG G2 was simple. " Paragon NTFS & HFS+ " is a free tool in Play Store.
NTFS is r/w now on my smartphone and r/o on the Mojo.
