Phone Portal/USB Mass Storage not working

I searched for this specific problem and couldn't find anything that helped.
1.) Phone Portal: I've used it before and after trying (unsuccessfully) to use it today I keep getting this error message:
"You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
(Error code: sec_error_reused_issuer_and_serial)"
Any ideas?
2.) USB Mass Storage: I did read a few threads about this issue and I guess it's just something that is a known problem with the Atrix 2??
With the issues with this phone (and it being my first "smart" phone...), I'm contemplating just returning it. There's gotta be something more stable/reliable than this.

Ive run in to issues where my phone just doesnt get recognized by the program. Only way I have fixed it is to do a factory wipe

Trying to not do that. Really shouldn't have to keep "factory resetting" the phone. Kinda irritating...

I use a mac so the connection is flakey at best, but I've found AirDroid to be a great resource for this.

As do I. But everything has previously worked fine. I haven't done anything different to the phone (completely stock, plus a few apps).
EDIT: Ok, so I may have found the solution. I just re-installed the certificates to my computer and it's connecting now.

After connecting your phone to your computer change the usn connection type to charge only and see if you can connect with adb. If so it is a problem with the crappy moto phone portal app
.. I have this issue on my mac book pro often.
You have to uninstall it and make sure it does not leave any thing in your preferences or library directories. Then reinstall the app on the mac.
If you can't connect with adb (make sure debugging is enabled in settings under applications first), return the phone and get an exchange for another atrix 2.

So far it's working again.
And I'm still on OS 10.4.*...so I can't use the adb commands yet. Working on fixing my optical drive so I can upgrade to 10.5-10.8.

As for the USB Mass Storage Device problems, you CAN NOT have ANY apps on the SD card. Sometimes apps install themselves automatically on the SD card, you just have to go back to Manage Applications->On SD Card->Click on all the ones with a green check mark and select "move to phone."

Just want to make sure on something here. Even if you move apps from the SD card to the phone memory, some app data still remains on the SD card right? And this setup will still have no problems with missing apps?

My third problem with Note 10.1

Hi Guys ....
The third problem which i have with this Note 10.1 : i cannot connect the device as mass storage , i tried everything , also search google , but no way ,
Does anyone of you make it ?
Thanks

I'm confused because every time I plug the cord from my Note 10.1 to my PC I can easily open my computer and see both my Note's directory as well as the micro SD Card that is housed in my Note. I can move files back and forth so I guess I don't see the issue here?

Wow, dude, what's up with the huge bold font? We aren't blind you know.
Could be due to the fact that ICS organizes its file structure differently. You can locate your SDCard in the /mnt/ folder.

I find the font and size quite nice and easy to read.

Erm...In case you haven't noticed, you can pinch to zoom generally if you find fonts to small .

could be having the same issue I am having. I have to re-install the drivers all the time because I keep getting unidentified device message when I plug in the tablet. I have installed Kies, tried installing the drivers not connected to the internet so the windows update will not take and the issue always comes back. It happens on this tablet and my GS3 phone. I read it was a windows update issue but I have updates set to let me decide and installed the drivers off line so I am not sure why this issues continues to arise.

It doesn't support mass storage, none of Samsung's ICS and above devices do. They use MTP. So does the GN and N7. Love it or hate it that's the way Google wants it. There's some work-arounds. Search the SGS3 forum(s); whatever they've done will work on the Note too.

MTP is the issue I am having. Computer fails to recognize the hardware, thus nothing shows up in my computer.

Download KIES, install it, don't run KIES, connect and that's it. With KIES You get the correct drivers .for MTP .............
There is absolutely no need for mass storage function ..........

My computer does not pick it up most of the time either.
Ive found that if I plug it into a usb, then restart the tablet, the computer picks it up then.
Have to do same thing with my Note phone.

MTP Sucks

With the latest (and unfortunate) update from HTC, I have come to the conclusion that MTP is not the best protocol to transfer files between 2 devices. Why? It's much slower plus less secure. Maybe I just wanted to charge my device when hooking it up to the PC. With normal USB file transfer, by default, the phone does not mount and show its files to the PC. With MTP it does; and there's no way to stop it. MTP is also less stable. I had freeze ups many times when transferring large files where my computer no longer recognized the device. I had to unplug and restart.
Is anyone else having issues? Or is it just me being on Windows 8? Anyone know of a way to disable MTP and use the traditional way of mounting to sync? Thanks.

Just got an option I'm going to try. I worked on other devices I'll try ours:
"Use system tuner app. Go to startup button. Check for mtp. Click on it and find the exclude button. Click on it. Restart your tab. Connect to your charger and see if it works. For me it does, but you probably have to repeat the step because mtp might appear in your startup again (i don`t know how to kill it once for all)."

Will report back. For all you's who don't mind MTP, disregard this thread

Em can you explain the 'less secure' bit? But ya it sucks lol.

in windows 8 it sucks like hell, im with you, but in windows 7 is working fine and super fast, i pass large files from my pc to my phone, and when i say large, they are really large. i use my phone for movies, and i download movies from 5 to 6 GB, and it take a couple of seconds to get from my pc to my phone. you need updated drivers for it to make it work right.

Em what that just bs for a start the filesystem don't even support more the 4gb and then you got the fact there is no way it would copy over so fast that it puts my SSD drive to shame.

I always reboot to TWRP and use mount as old USB Mass Storage.

Bull****.
MTP cant get over 2MB/sec even when using a high-end PC with SSD HDDs and USB3(yes i know the S doesnt support usb3, thats not the point), while USBMS easily do 10-15MB/sec, and ADB 5-6MB/sec.
MTP is worse than useless. Good thing I coded Quick ADB :silly:

MTP & the suck
I can agree on the initial frustration I had, trying to understand why my other android device allowed the copying of any file ext. onto the SD card. I bought a new phone with the same ICS os(phone did not come with a file manager), when I learned of MTP then what I learned now was that mass storage no longer exists . It is a more secure way the computer reads the device, so to avoid the blockade you'll need another device anything that has m-sd card capability so you can dump any one or more files onto it first off. Then goto googleplay and dl a good file manager program to use while accessing file in the phone. It should be simple from then in on to install any backed up .apk files or view any media(phone did not come with a versatile media player)files.

did not work for me, mtp still loaded!
i hate mtp, every time i copy a image file or video from my phone, it is corrupted, windows 7 or xp.
sometimes my wallpapers get corrupted just using es file explorer or just what seems randomly.
this is on my verizon note 2, running stock JB 4.1.2
anyone find a real solution yet?
if i have to root to get this solved, so be it, but i am about to do so any way since i miss having more control over my device.
turns out after testing, my sd card is a faked 64gb class 10, transfer rate suggests class 4 and 4gb of data was verified, good news is i can still get my money back and my friend who sold it to me may not have known it was a faked card.

MTP is completely retarded. UMS is a tried-and-tested protocol, this is the biggest sh*t sandwich Google has handed Android users so far.
MTP crashes every single time I try to use it. Try opening a folder that contains a large number of files. Explorer will freeze. Furthermore, MTP requres a device-specific driver, whereas UMS uses a standard driver. Oh this sucks so much!

Guys, I don't understand you really... In every ROM I've flashed lately being it AOSP or Sense based, there's an option to switch from MTP to the "old" UMS mode. In AOSP based ROMs it is usually located in Settings - Storage and you should open the menu there and you have USB Computer Connection where you can choose whatever you like. It is an option like any other options, you can use it or not
And yes I agree with you...it sucks

I am on a rooted S4 MINI using the original stock ROM. Other than this small niggle, after removing all the crapware I am pretty happy with what I have, although if there is a compatible ROM that would bring UMS to the table I'd be happy to try it. I just find it very annoying that earlier Samsung phones used to have the UMS option but recently they decided to get rid of it. That's as stupid as it can possibly get: a tried and tested, working feature that was already in place... WTF not just leave it there??

I know CM11 has the option included and I'm sure you have either an official or a CM11 port available for S4 mini

[Q] USB MTP not working

For the last few weeks I haven't been able to get any PCs to see my phone (tried my personal, work, and one friend's, all running Windows 7). Previously it would mount as an external drive just fine (MTP) but now I really cannot get it to connect to any computers so I'm having to do all file transfers through Dropbox and stuff.
Tried a few apps like the SGS3 Easy UMS but nothing works. Does anyone have an idea what might be wrong? Thanks in advance for any advice.
I've been updating to the "last stable build" of CyanogenMod 10.1 and now 10.2 from the ApexQ team about once a week. Not that I really know what it means.

Did you try different cables?

Try downloading all drivers for our phone and using last 10.1 nightly. That's what I'm on currently on and just used 2 days ago and had no issues. Most importantly use cable that came with phone!
Sent from my SGH-T699 using xda premium

Thanks for all the suggestions. Downgrading to the last stable 10.1 nightly seems to have done it. Same cables used throughout.

having issues with that too from time to time. reboot sometimes helps, shutdown, pull battery and wait a few secs then put it all back together always did.
may be related to the otg-driver they are fiddeling with atm. seems like the chip gets stuck in some mode which makes the device invisible (doesn't even show up in kernel logs as if it wasn't connected at all)

we're just adjusting for a few differences in the 3.4 kernel (plus all the nutty caf patches d2 loves) and adding new features at the same time look for otg in a build near you soon. At this point it's not "does otg work" but "how can we best implement this in our shared kernel" and "can we also do usb aca" (otg + charging at the same time)

my phone's rooted, but i decided not to put CM on it.
anyway, MTP is pissing me off.
everything i try to put music on it from my computer, it doesn't recognize it and puts it in the LOST.DIR. What's worse is that I can't delete anything I put on the SD card. It says it's protected.
I've tried putting music on my sd card using another phone with usb mass storage and exchanging sd cards, but it gives me the same result.
anyone have a solution to this?
i've tried usb mass storage enabler, airdroid, and kies. none work.
any help is appreciated! thanks!

Sounds like your sd card. Try a different one.

no usb notification (PACMAN)

usb debugging is checked in developer options, phone appears as photon q and mot composite ADB interface in device manager and windows explorer. i have tried 3 usb 2.0 cables and a usb 1 cable. 2 of them were labled as "data cables" and have worked in the past. i have installed the Motorola software previously. only internal storage DCIM and pictures folders are viewable through explorer. i suspect the phone is recognized as being in camera mode but since there is no notification i cant change this. i do have an sd card in the device that is recognised by the operating system. so whats the next step?

Have you tried the original Moto cable?
Have you tried clicking on the notification from the shade and changing the mode?

yes i tried the moto cable and what mode toggle? the network one from off to on yes, and i tried the lte off and on, even reset apn's. the only thing that seems to work is a reboot which only works for the first 3 mins or so. issues started after i flashed nightly. im gonna attempt to do a clean install of nightly. if that doesnt work i might have to stick with rc2
edit: im going to have to call the carrier and see which apn they recommend because i have 5 for sprint

did a factory reset and reinstalled pacman rc2 running smoooooth. wish i could have rc3 though :/

nah now my sd card isnt recognised and i dont have a spare or another device to test if its the card. no mount options in the menu. i also figured out that theres a way to change mtp and ptp via the three dots in the storage menu if anyone gets this problem. also i have no service, idk if theres a way to improve reception from the phone.

You seem to have an unending fountain of issues. Try flashing stock and seeing if they persist. You may have a hardware issue.
You should have some sort of way to plug the SD card into your computer - IE a converter card or a USB-to-microSD key. I guess I always make sure the card comes with one kind or another so I have a few laying around... You can buy one pretty cheap too, especially if you have a MicroCenter near you.
