Kingston 8Gb Class 10 issue

Hello everybody,
I bought the above micro sd card but the problem is when installed it i realised that the phone dont seem to be able to able to mount it...
what should i do ?

Is it formatted to Fat32?

The more important question is what message it shows when tried mount it.

I have had the same isue, only way for me was to use a RUU file

You can also try formatting it with Android.

it says something like unable to write ums lunfile

I googled and found this on a other forum:
Code:
I get error mounting sdcard (no such file or directory) and unable to write to ums lunfile (no such file or directory)
Edit: I Solved the problem by rebooting into recovery using rom manager. Thanks.

It's interesting how can be people independent and resourceful if the really want to. Then why we have so many question threads are beyond my comprehension.

Of course i googled before asking this question..
The problem is... I boot into recovery but i cant mount my SD. I used other phones and the card is recognised normally
An alcatel one touch 908 and my previous HTC touch HD.
I'm running Leedroid 3.3.3 Data++ version which means i cant boot without an sd card becouse many things run from the sd-ext partition and of course since i cant mount the SD i cannot even flash again Leedroid or any other Rom.. so i cant simply reboot into recovery using Rom Manager.
But since u told me all this i'm going to simply install a clean CM7 nightly and try to reboot into recovery via rom manager..

USB brick. Search for solution.

My usb working flawlessly. Everything happening had to do only with this specific card

As far as I know unable to mount sdcard is part of USB brick.

i can mount any other sd card but this specific one.... and i try to find what's wrong here..

Fire up Android and format SD card with it.

Where the hell did you get that information? The fact that an SD card cannot be mounted is not in the least related to a USB brick, they are two totally seperate issues. You may find that on restoring SD card functionality that you then have a USB brick but it's not necessarily so and it cannot be ascertained without first fixing the SD card issue (and by the symptoms as described I highly doubt he has a USB brick).
To the OP, I would suggest that you copy everything from the SD card to your PC via an SD card reader. You can then either format it via G-Parted (Linux bootable disk) or via MiniDisk Partition Wizard. Copy everything back plus the rom of your choice.
You'll then need to flash the rom (assuming that your phone now 'sees' the SD card). You're going to lose everything that you installed, there's no way around this. The copy back and forth is to restore your music / photos and if you're lucky one or two of your apps may find an existing file of history to restore.
Please also report any messages the phone gives regarding the SD card and also try another SD card (if you have one) before you go the above route.

wierd things happening....
When i boot into recovery with power+vol down i cant mount my sd but if i do it through rom manager it works flawlessly... anyway i kept it this way. I installed a clean CM7 build formated my card and then all the things i do i do them via Rom manager...
btw i see speed increase using a class 10 card compared to class 4

what are the recoveries u talking about?
when u go in recovery with power+vol down u access the permanent recovery (what version?); while using rom manager u access another recovery version probably (as rom manager use fake flash, even if the latest version should use permanent flash)

sorry for being late answering..
both recoveries are 5.0.2.0

Need help asap!

ok here is the situation, i got clockwork recovery installed and wiped all data to flash a new rom, but my phone wont read the memory card so i cant flash the rom. How do i mount the phone to move the rom over to the internal storage with clockwork or how do i flash a rom using odin.

Does the phone boot up? If so, are you saying that the SDcard isn't being mounted or are you referring to inside clockwork?

the phone boots up, but i dont know how to put the rom in the phone so clockworks will see it

Im trying to mount the sd in clockwork but my computer is not seeing it, any ideas?

Get an actual sd card
Dont use the phones virtual sd card

In the blue clockwork, go to install zip from sd card, then select the option above the "go back" option, I believe its choose from external or something.
Sent from my SPH-D710 using xda premium

Edit:
you can flash from the external from the external sdcard if you go to
Mounts and storage
and mount emmc - if you have the option. Once that is done go to flash zip from sdcard, then (and this part is counter intuitive but) select
Internal sdcard - and this will actually take you to your external sdcard.

It depends on what kernel your running. Some kernels with CWM are not "fixed" to see the external sd card. To make things worse some of the kernels won't allow usb mounting. I'm on Chris41g's kernel and it does in fact see and flash from the external sd.

[Q] SD card slot "dead"?

I have a R800a with unlocked bootloader. I was using CM 7.2 until a friend pointed out an update that made jellybean roms more atractive, so I went for CDan's Turbo JB kernel and CM 10. Then I realized CM 10 could not recognize my sdcard, so I rolled back to CM 7.2. Since then, my card slot does not "work" properly, I've tried exchanging several times, even went back to stock ROM. Even CWM recovery gives an error when trying to mount sdcard. Anyone can help?

Did you try blowing air inside?

As a matter of fact I did, but to no avail. I've also fastboot a recovery image, but it isn't able to mount my SD card. Using other SD cards, and reformatting isn't useful either.

Format your sd card. I know that sucks to hear. You should still be able to mount to pc through cwm if you don't have a memory card slot.

I had issues where some SD will not get recognized by CWM. Use a different SD card.

I've tried those things, but still can't mount the SD card. The SD I'm currently using is recognized by my PC with no problems, and all others I've tested on my phone are working too, just not on my Play.

Need help ASAP

A little while back I posted a thread asking the following.
"Just recently rooted my friend's GN2, I transfered the files to the SD card and went into CWM recovery. I'm having 2 issues.
1: The phone says there's not enough room to make a backup when there clearly is. I have about 2 gigs on the internal, but but it either says I have 3mb of free space or 0.
2: I click 'install from SD' and the only file it sees is "-clockworkmod/ ".
What am I doing wrong? I personally have an S2 and it's very similar but these two things are preventing me from flashing any rom"
The only person to respond recommended I format the sd card so I did so. However the phone still did not recognize any files in the sd card so I couldn't flash any rom. Upon startup it began boot looping and the phone is no longer activated? It can't make calls or send texts and reboots every minute upon ' failed activation'. The phone currently is useless. I'm not new to flashing roms I've been doing it for years but this is the first time I'm stumped thanks to some bad advice (not blaming that person) and it's not even my phone. Luckily I just got an htc one and I could give my friend the my s2 until the problem is fixed...any ideas how to fix it? Or unroot at least to bring in for repair?

Try using twrp instead. Sorry I couldny be more help. But I have never used cwm on this phone since I got it. Only twrp. You can find it in original dev section.

Yes use twrp. Find the latest version and flash it in clockwork. I havent used cwm since my og evo lol.

Maybe I'm old school but I'm a long time flasher and I've always just been more comfortable with cwm. But I'm not so sure it's a kernel issue?
Edit: and the issue is that I can't flash anything because I can't store anything on the sd card. I'm thinking of odining to a stock build?
Sent from my HTCONE using xda app-developers app

The only thing I can suggest is doing a quick format on the SD card to FAT32, especially if the card is a 64 GB card. Also, some Sandisk 64 GB cards were bad from the factory, so check that too. Finally, if all else fails, try breaking the phone even more to the point it won't even boot and get a replacement.

Don't come up with one. Just take it in and show them. Before you take it in, if you can, try to reset the flash counter. If they can check that and see it isn't correct, you're in trouble. If it's reset or it can't be checked, then take it in.

Ok...what files did you transfer to the sd card? Was it the internal or external? Even 2 gigs on the internal for a backup may not be enough. I have a backup that is just over 3 gigs. As far as formatting your external sd what did you do ? Fat32? Personally TWRP is the way to go. Try to format fat 32, download a stock rooted TW rom and put on external sd, also dl TWRP recovery to external sd. Boot into cwm recovery and try to flash twrp. If that works out pull battery put back in volume up+home+power. Hopefully that gets you to twrp, if so go to wipe then factory reset. If you click on advanced it will let you wipe system which couldn't hurt. After that, back arrow on bottom of screen to twrp home screen. Click install...choose external then locate where rom is...hopefully on root of external and see if that helps.
Oh and was the phone activated prior to flashing?

Please do the following:
01). Format the SD card to FAT32 (NOT EXFAT OR NTFS) on ANOTHER computer and do NOT use the built in windows format options. Use a third party tool like guiformat.exe and do NOT USE QUICK FORMAT. (With my current sd card, windows format failed, guiformat.exe partially failed(and by failed I mean formatted fine but caused problems being seen) but I installed and used eausus partition master to regular format it to fat32 and followed the next few steps and its been working fine ever since.
02). Immediately after formatting the SD card slow format to fat32 in easus partition master create a text file on the sd card in its root directory (I've had an issue before where my SD card would not be seen or writable by certain devices if the root directory was 100% empty), before you copy any further files insert the SD card into the phone and use your recovery kernel(CWM/TWRP) to navigate to the root directory of the sd card and insure that you can in fact see the text file you created, POWER OFF THE PHONE(or alternatively unmount it in android terminal if possible) before removing or inserting the SD card(also always eject from the PC before removing, do not just rip it out off the usb slot/card reader), insert the SD card back into your PC/card reader and copy TWRP to the sd card.
03). Boot back into your current recovery and Install TWRP(if it's not already) you may prefer CWM but TWRP just causes people a lot less bugs in general.
04). Verify in the backup section of TRWP that you have explicitly selected external storage as the backup location and given the backup a name, as internal storage is selected by default, and you very well may not have enough free internal storage for the backup, regardless of whatever reasons you think you should.
05). Its probably a good idea to turn off md5 verification of the backup, I do this every time, the one time I did try to verify a backup with an md5 checksum it failed, I unchecked this option backed up restored to it and all was fine(and still is), also a good idea to uncheck md5 when installing roms/kernels/apk's as most don't have md5.
05). If the above does not work you probably have a bad SD card, try another and post back here.

There is
no external sd card in the phone. Just a 16g internal, and I've wiped pretty much everything so there shouldn't be a problem with room. I'll go out and buy an external and attempt to flash something.

Il if you are treating the phone plugged into a computer via USB the same way you would treat an external microsd card you are making a huge mistske/misconcepyipn ..
I am at work right now so I can't help further but at this point you need to.find and follow the instructions to restore the phone back.to its stock state and start from.fresh. I will post back tonight with instructions to do that and the best way to root and custom recovery currently when I get home

Thanks. The problem is that the phone boot loops so fast that I can't stick anything on the internal. And the one time it was on long enough to, the phone still reads that there's no files there. It's why I'm in this mess in the first place, I don't know why it's not recognizing any files

If you wiped everything then you might have wiped the partitions by accident. Get an ext sd card put flashable rom on that then boot into your custom recovery and try flashing the ROM through that

Odining back to stock is prooobably your best bet. No need to go through repair fees or restocking fees etc. When you can fix it in house.

It should not rely on the internal. Download mode is deep down in the bootloader. If you borked that then jtag or sending it to samsung/asurion is the only option.

Try a stock rooted rom and see if it works. Because it should at least give you the boot.img in the rom so you might be able to get past the boot screen. Hopefully it will re partition your phone. Im not for sure but its worth a shot.

[Q] CM 10.2 External SD card issue

I just installed the CM10.2 and am finding it difficult to work with the external sd card.
The sd card shows up on storage and I can mount and unmount it without issues.
The card will not be available unless an app is rooted.
I cannot use it with CoolReader which I used to do when I had the stock ROM.
CoolReader will only show the internal card.
File Manager will also show the internal one only unless root is enabled for it.
I did format the card through recovery as well.
Is it not possible to use the sd card without root privileges?
I had thought by installing a custom ROM I would gain more capability but I seem to have lost here.

Sounds like either an issue reading the card or a broken symlink. What kind of card is it? Try formatting it as fat32 on a computer.

It's a generic 16gb card class4.
I formatted it from recovery which I understand does fat32.
As soon as I revert back to stock i am able to use with all apps without a problem.

Try another Rom, one built from CM and see if it works. And be aware android devices tend to be really finicky when it comes to sd cards. Sometimes you have to format on the device, but sometimes it works better if you do so on a pc. I still say it's worth a try. Then if you still have the same problem, you might consider searching and asking in the Rom thread.
