Hey,
When I try to install any application to my phone its giving me an error saying 'could not install on usb or sdcard "
Any ideas on how to resolve this issue?
I've tried rebooting and the whole battery removal deal. My sd card is not set to read only. And applications are installed on the phones memory then I move them to my sdcard if I need to.

That is the name of the recovery.
What ROM is your phone using? Like CM7 or Myns WarmZ?
Also, what app are you trying to install and how are you going about installing it?
I noticed this on another site the other day. http://www.androidpolice.com/2011/0...on-usb-storage-or-sd-card-problem-on-android/
Hope that helps.
That's the exact problem I am having. Problem is, that file is not in my sd card!
How do I find out what rom I'm using? Its not in setting.. about phone.
I can you my phone is rooted using unrevoked, and I have never changed any rom or thing like that... its just been unrevoked (the latest one) and that's it... then I just install apps. So, the default rom?
And the difference between my problem and the one you posted is that All APPLICATIONS CANT BE installed, not just some... but it's the same error, exactly as it appears on that link above.

What program are you using to view your SD card? As the article suggests, use Root Explorer to search for the file. You may not be able to see "hidden" files using other explorers. Root Explorer is the default ninja app. ;+)
As far as "what ROM," if you've only used unrevoked, yes, you're just on the stock "default" ROM, albeit a rooted stock.
I was using esfile explorer and I did select the option to view hidden files but that didn't show me everything, apparently. I know this because I connected my phone to my pc, view the files from there and then I found this stupid file that causes this error.
I didn't have root explorer and obviously couldn't install it because of the issue in was having.
Thanks for the help everyone! Much appreciated.

Glad I could be of help! Happy EVOing!
can anybody make a flashable script that will install apks?
anybody know how to do this? or direct me as to how i can do this?
Here you are:
http://db.tt/o9TkEvtG
Let me know if that doesn't work.
Extract it with a file manager, and put your app in the app folder. Rezip and flash.
EDIT:
Fixed , tested, and uploaded at 9:34 p.m. central.
Sorry about the 1st one.
I gave it a try with several different apps. It aborted install and gave a status 6 code.
I followed your instructions to the letter. I I also tried through astrology by dropping app in app folder....this way I wouldn't have to unzip and rezip. Gave me same error.
I love this idea for non system apps.

Hey, sorry. I fixed the other one, tested it, and went ahead and made one for system apps as well..Dalvik will need to be wiped for either of these after flashing, of course.
Here's the system one:

EDIT: i create a folder in the sd card or what do i do?
Hi, I have a problem with my patriot signature microsd 32gb on my 16gb Samsung Galaxy SIII which I use as a music and picture storage for my music player and camera
The phone is rooted and is running stock ROM and kernel
The problem:
1)when transferring music files while the sd card is in the phone, using a usb and explorer method of copying and pushing sometimes the write protected warning pops up, other times the file would copy but I could not find it in my music player/gallery, other times the file is present for a period of time but after a restart of my phone the file disappears.
NOTE: However, files that I have transferred using the microsd adapter and directly through the computer does not change at all.
2)On the default camera I have set up the external sd card as the default location for pictures, but when I take a picture sometimes the warning that "sd card cannot be located and default storage is changed back into phone"
3)On Android Commander when I try to push music files it always ends up as permission denied
4)When I try to copy music through the windows explorer this message pops up "the device has either stopped working or is not responding"
What I attempted:
I thought it was a formatting problem and so I tried to format the sd card using both my phone and pc into the phone's desired FAT32 format,
but the problem persists.
I have also inserted the sd card into the adapter and put the write protected switch up thinking it was a permissions problem
Is it a faulty card? or am I doing something wrong?
Additional Note:
1)I have both ES file explorer and Root explorer and when I attempt to change the permission on my external sd card which usually appears in ES file explorer as "rwx-rwx-r(blank)x" it always fails
2)When opening the gallery and trying to view some of the photos saved in the external sd card, it would appears as unable to load and just a black screen.
3)I also export playlists from itunes in m3u format and puts it in a playlist folder in the sd card but it would never appear when I try to see it in a file explorer, although using poweramp I can import the list, but the old ones that I have placed on the card is also present unable to find them or delete them in either the phone or the pc
I have really became desperate trying to solve this problem
Please help me
Try reformatting as exFat. Also I don't think you can change the permissions on the entire sdcard.
It could also be that the phone connects using MTP. There's an app here on xda called sgs3 easy ums. It will mount the card as a UMS device. Try transferring that way.
I think the sgs3 was intended to use the exFat format though.

I have a problem with my card right now for my SDS3 (see sig) but my problem is completely different from yours. Hope that helps solve your problem.

That's weird. If it doesn't pick up your card then the problem might be more serious than you think. But how can you see the contents and be able to format it yet utilities like Easus and SDFormatter can't see the drive? Did you try disconnecting all USB flash drives, your phone or other devices connected to your computer first? Check explorer and see to it that your card is the only one connected with a drive letter. Go to SDFormatter, hit refresh and make sure the drive letter is chosen.
SDFormatter just fixed the problem I was having.
You said you were rooted stock. Did you do any debloating or anything else to it. I doubt its the case but maybe something needed was accidentally removed.
Have you tried running fix permissions in recovery or TiB?
Also, how did you root? Was it recent and did the card function properly before? If you used odin to flash a rooted fw, maybe it was a bad download?
If all else fails, you could try reflashing the full stock fw with Odin.

1)I didn't do any debloating for my phone, and how do you run fix permissions in recovery? or TiB?
2)I root my phone by following this guide "How to Root U.S. and Canada Galaxy S3 SGH-T999/SGH-I747/SPH-L710! [Fail-Proof][Noob-Proof][U.S. Cellular]" using odin
3)So by reflashing the full stock fw do you mean I need to factory reset? or Is it possible to download the stock fw somewhere?
Sorry I am new to android, so please bear with me
Sorry, coulda sworn you could run fix permissions in Titanium....
You should be able to do this in cwm or twrp recovery. May be in the advanced menu. You can install the recovery from Rom or Goo Manager app.
Factory reset wipes all user data taking you back to an out of the box state.
You can get a pre rooted version of the FW from here.
http://forum.xda-developers.com/showthread.php?t=1771687
This is the original LE6 version though, if you want the updated LH2 version give me a few min to get the link for you.
Follow directions in that thread to flash with Odin.

thank you so much for taking the time and finding that for me!
i will definitely try it as soon as i can!
thanks again
NP.
Let us know how it goes. If noting at all seems to work, try borrowing a sdcard and see if it acts the same.
Could always just be a problem elwith the card itself

I had a patriot 16gb class 10.. when it works.. it's awesome should be called class 15 or something lol. However there were three times it randomly corrupts.. lost all my pictures and crap. A format usually fixes it. After the second time... i learned to put my photos to default internal memory. The third time i was no longer able to format it... couldn't move files in or out but i can open them?! I went with the high amount of 5 star reviews but should've listened to them 1-2 star reviews. They don't do well with phones. And your problem is a problem that occurred to me every now and then. Remember to back up your card frequently before it crashes!

ah, problem
so I tried followed the link and the steps to flash the fw
but I am encountering this problem of when odin is done and the phone is restarting the "process android.process.acore has stopped" along with touchwiz and poweramp.
I reflashed twice and the problem remains
I even cleared dalvik cache and regular cache and fixed permissions with cwm and rebooted but it still did not fix the problem
Do I have to factory reset now?
:crying:
I can't remember which app it is or if this is the one requiring factory reset. Can you boot and get to settings > app manager? If so clear data on google services framework. Maube also touchwiz home. (Can't remember for sure)
You could also try using the built in file manager in twrp. Go to /data/data and look for those folders and delete them. May not work but worth a try.

ya thanks for the advice but it didn't work
From what I can tell the only solution now is to do a factory reset
anyways so why did the fw not work for me?
i even made sure i downloaded the correct wind one
at least now maybe with the factory fw i can make sure the external sd card works?
so factory reset is done
external sd card still does not want to work via "my file" folder creation
I don't know is it broken? I would like to try another sd card but I need to find one
although I did test it with h2testw and no error message popped up.
It wrote and verified fine.
Sometimes left over data can cause problems with a newly flashed system. Odin didn't wipe your apps or data and something was left behind that conflicted with setup or something like that. Sorry it came down to that man.
Ive heard a few times over the past couple years of sdcards working fine in one device but not at all in another. It seems rare and I'm not sure why it happens, but it can.
Only way to know for sure is to borrow a known good sdcard and try it. If it also doesn't work then its most likely a problem with the phone. If it works then you probably need to replace the card. Maybe take it to the store where you got it and let them try. That way if it doesn't work you have a witness that can note your account of the issue.

So whenever I try to flash a ROM I get the following error:
E: unable to open zip file
Erorr flashing zip '/external_sd/Infamous_S4_v2.5.zip'
Updating partition details
I've had the problem since yesterday and have searched different threads with the same error but none seem to have a solution.
I've read that it could be the file and I have since redownloaded the same ROM several times and downloaded different ROMs and all give the same error.
I've ODINed back to stock and re-rooted and reflashed the TWRP recovery.
I've formatted my SD card which was a HUGE pain but it was one of the suggested ideas in the other threads.
And I STILL get the same error. I have no idea what else to do. I was fine on Infamous s4 2.4. I wiped and flashed 2.5 and i lost my status bar. Someone suggested to download and reflash and that's when the problem started.
I got that error, as well
What I had to do was to download it on a computer and use a cable to transfer it to my phone.

I would venture to say it's a bad download. Maybe try downloading again?
Ive downloaded 3-4 times. I've also tried other ROMs. I tried to go back to Infamous 2.4 it wont flash. I flashed the google edition and it did work. The wicked rom also works. But v 2.5 and 2.4 of infamous don't flash.
I did not try flashing from internal. But I guess since I got wicked working I will just stick with that

Can you browse through the zips either through a file browser or on your computer? I kept getting that error with Faux kernel a while back. Thought I'd try to browse through the file on my computer and it would tell me it was an invalid file or something of that sort. I downloaded the same file maybe 8-10 times before I got one I could open; coincidentally enough, the one I could browse was the only one that would flash. What I'm saying, if you can't open the file, then it's a bad/corrupt file; regardless of whether you've downloaded it multiple times or not. If you CAN open it, then the problem would lie elsewhere.
Check your recovery and make sure its updated
I had same problem. It's a bad download. I got it 3 times from same rom and was determined to get it to work. Either download to computer or if using your phone make sure to download from different links. I couldn't navigate through the zip either. So maybe it was a bad upload or download.

You guys are right. Even though some I downloaded on a computer, I just tried opening with root Explorer and the files wouldn't open but the good files did open. I guess that was it all along. I've never had so many problems downloading roms before. Wish I had known before wiping my phone and sd card lol

I have been having the same problem ever since I downloaded and flashed the GE 4.3. I can't even restore my backups that I have been using just fine before I flashed GE. I have noticed however that the problem only exists with my backups on my external SD card. The one backup I have on my internal is the only one I can restore. I don't think its a bad download problem, only because it's causing my MD5's on my external to mismatch, when I never had that problem before GE. I downloaded Infamous 2.6 4 different times to my computer and none of them have worked. I really want this as I like the GE (not Jamison's Rom GE) but it just doesn't give me what I want.

If 4.3 changed external file handling again, you'd theoretically get that response again until you wiped both external and internal storage so it could be set up as 4.2 format again. Just backup both to your computer and move things back afterward.

I don't see how it could be GE4.3 doing that. I flashed 4.3 a few days ago and decided to go back to TW; my backup worked perfectly. All of my backups work and all of my flashable zips work. I store nothing on my internal storage; it's more like temporary storage until I move it to the SD.

I havent had issues with backups so far thankfully. I use titanium to backup and restore my apps. I've also never had any issues flashing ROMs before and I've been doing it for years.
As the previous poster suggested, it seems I keep getting bad downloads for infamous roms no matter what server I use to download. For now I have switched to wicked rom and like it.

Yeah, the backup problem is curious... not sure what could have gone wrong there, but the problems with downloading Infamous would most assuredly be a bad download. Would have nothing to do with the file system on the SD card if the zip can't even be opened on the computer to which it was downloaded.

After I posted, I was browsing my photos that I took last night of my kids enjoying the fireworks. I noticed that a lot of them were just not showing up in the gallery, and the videos would give me a could not play this file error message. So I thought maybe if I unmounted and remounted the SD card it would fix the problem, like it used to with my GS2. Well once I unmounted it, it would not remount. So I took it out and placed it in my tablet. Nothing. So I restored stock 4.2.2 and when I rebooted it said my SD card was corrupted and needed to be reformatted.

Pop the card into your computer and format to FAT32. That should get it into working order.
So here are the problems. ...
1) I have the XDA Premium app and when I open it, it says "Connecting to server.." and it won't load. I tried clearing the cache and even uninstalled and reinstalled the app. Still the same problem and I can't find a solution.
2) I am trying to download a .zip file from Chrome (I have done it before) and when I click on the link it says "No SD Card". I can still access my pictures and music and everything else.
With both of these issues I will add that I recently did a full factory reset and took a wrong turn somewhere. My phone would sit in the Samsung Galaxy S4 loading screen and for some reason TWRP wouldn't show my backup file on my SD Card until a few hours later, with trying to find my stock carrier file, my file randomly found my backup. I installed the backup, everything was good, but now I have these problems. It's probably nothing big, but it will be greatly appreciated if I can fix this.
Thanks in advance :fingers-crossed:
