Micro SD Card no longer recognized issue .... - Transformer TF300T Q&A, Help & Troubleshooting

Ok, I have searched high and low to try and solve this issue without having to post it on the forums. There are several old threads about the Micro SD having issues here, and many many more across the net. At any rate let me start from the beginning.
So, I decided to root my stock tf300t and try the KatKiss 6.0 rom. Micro SD working excellent at this time. I also installed TWRP recovery image 3.0.2.0. Then for some simple reason ( read it somewhere) I dropped back to TWRP 2.5 and Micro SD still working excellent at this time. So, everything is great up to now.
I had found out that I had not formatted to f2fs and somehow with my big hand while doing so on the bootloader screen my pinky brushed the wipe data button. Yep, I lost it all and was stuck in the splash screen or TWRP 2.5 If I booted to recovery. My Micro SD and my TF300T's system files (all of them) showed 0mbs across the board. My file partitions were a mess to say the least. --- I posted about it in another thread.
Finally with the help of forum member gs-crash-24-7 I was able to flash the factory rom back to my TF300T and got my tablet back, with the exception of the fact my Micro SD no longer shows in my Tablet or on my pc when plugged in via the data cable. Now when placed in a card reader on the pc all my files were shown on the MicroSD< so I saved them elsewhere and using SDFormatter did a complete format and complete overwrite. (currently in fat32 mode - but have tried them all) Put a file on it and the pc reads it like a charm.
So, I went installed KatKiss 6.0 again in hopes the MicroSD would magically show up, also installed Kang TWRP 2.8.7.2, pico gapps, and supersu 2.52 to gain root access. But to no avail, I still have a Micro SD card that works great in my Galaxy S5, TF101, and my pc. I tried several different Micro Sd Cards as well, from a 128mb to 8gb one, which is the card I use in the Tf300T.
Ok, throughout my search of the net I found a similar issue that had been solved by adding a few lines of code to their phones permissions/platform.xml file. I have not tried this (honestly it was late and I forgot to bookmark where it was posted. lol Anyway, I did however go into my platform.xml file and did not find very much code in there at all and nothing mentioning External Storage R/RW etc etc ..... so Now I am wondering if I should revert back to JB 4.2.1 and start over in hopes it will restore my files and Micro SD. what are your opinions????? Open to suggestions.
Or if someone who has an Asus TF300T with a custom rom or factory rom (with a working MicroSD, could possibly take a look at their Platform.xml file and see if what is mentioned in it about External Storage etc .... I really feel like something somewhere that got deleted/wiped was not rewritten during the unbricking of my TF300T.
I Thank you in advance for any help or suggestions you may have to offer.

Flash back to stock 4.2.1 JB and still the card does not show up when inserted.
If I add the following lines into my system/etc/permissions/platform.xml file do you think it would bring back the ability to see my External Micro SD?
Code:
<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
</permission>
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
<permission name="android.permission.ACCESS_ALL_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="sdcard_all" />
</permission>
Anyone ever try this?
BTW, my Micro Sd was working just fine in the tablet until the accidental data wipe. I am stuck here, I would really like to get the ability to use the Micro SD card/cards again.
Thank you in advance.

It seems there is an unknown issue remaining after things you have done in the past. Please start your TWRP and "Format /Data". It may take one hour plus. Wait patiently until it finishes. After that your system is clean. So you can clean install the ROM of your choice. Simply follow the install instruction given by Timduru carefully!!! Finally the SD card issue should be solved.

Thanks will give it another try.

Several attempts at this using the latest stock rom and my own twrp backup (from when the sd card was showing up) and still not showing up. Tried to change files system in twrp and got this e:block device not present, cannot wipe ext_sdcard .... only close reference I found so far was in the following thread and according to post #16 my sd card partitions are not correct???
https://forum.xda-developers.com/tr...kang-twrp-tf700t-2-8-x-xarea51-t3049395/page2
also, according to twrp manager:
Storage Info
External SD Location
/Removable/MicroSD
But of course it does not show up in file manager. Thoughts?

This thread deals with Data2SD. That's not your problem. The SD card should be FAT32.
However what's the result of Format /Data? Has it been accomplished successfully? Does your TWRP finally show the external SD card?

No, I have yet to get it to show any SD from 128mb to my 8gb card, I have tried them all. The card is formatted in fat32 (I have tried all formats though). The only time TWRP seems to see it is if I want to fix or change the file system, (now when I was in twrp 3.0.2.0 was the last time it worked) TWRP shows it as vfat. If I try to change it I get the error string below (red text).
All of this started when I corrupted the partitions in the tablet and had to flash a factory rom on to get it going again. Since then no SD card, well actually no SD card while it was corrupted either only before the mess I made.
I feel confident that the SD card issue has something to do with where it's actual path or permission might be placed or written. As the card works excellent in my galaxy s5 and Tf101 and Windows. just not the tf300t. Attached several images maybe one of them will give a clue. Keep in mind under mount, when I choose the Ext SD it just greys out and will not accept a check mark for selection, same when I choose where I want to install a file from.
Again thank you for your help.

Well I have tried going back to the latest stock rom and now I am flashed to the latest KatKiss 7.1, but still no luck. is it possible that somehow when I messed up my file partitions that it, that they just will not clear up completely for some reason? Grasping here I know.

This happened to me and I am still currently dealing with this. I believed that there is a problem with that device recognizing the SD card, as in the card is not making contact with the device. The SD card comes up as corrupted when the ROM is running. I had to side load the last few time through TWRP to get a new ROM flashed because I wiped everything. On this last try I was able to get the device to recolonize the SD card by pushing and hold the SD card all the way in and holding it there for the duration of the flash. I went through all the same as you did including flashing back to stock. Sorry you are dealing with this.

Thanks, I will give that a try also when I load my next rom.

Tried the hold the Micro SD card in deal, didn't work for me.
So now I am currently on a clean install of KatKiss 6.0 with same results. Micro SD card not being recognized.
My install process:
Wiped everything then formatted data
Even fastboot erased everything again just in case via fastboot:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 reboot bootloader
Flashed KANG TWRP 2.8.7.2
Wiped davlik and cache, then changed data to F2FS file system
Rebooted to Bootloader then entered RCK / KANG TWRP where I did a TWRP BACKUP (it will not backup I know this) so I would have the TWRP folder it would create, so I could load my zips etc, once I was no longer in fastboot. Once in Twrp, you can see internal files then like the TWRP folder, where transferred my zips via the pc to. (now I have a place to load them from)
Loaded the Micro SD just in case with my zip files and also copied them from my pc to the TWRP folder in tablets internal storage.
disconnected from pc and loaded MicroSD into tablet slot.
rebooted into recovery (TWRP still would not load Micro SD ... so plan b) from internal storage via the TWRP folder that was created I flashed all my zip files together:
Flash KatKiss 6.0 rom
Flash the SuperSU 2.52 zip
Flash gapps nano
Wipe cache/dalvik
Reboot
Everything was done per Timduru's instructions, except where I had to load my files via the internal TWRP folder, and I use the Nano gapps over the pico. Also, one tablet reboots to the system i updated the SuperSu Binary.
Some of the Erasing was probably overkill, but I was trying to clean as much as I could in hope my Micro SD would show back up.
Tablet is working fine, in fact very fluid and speedy. I just do not have access to my Micro SD card, except via a usb adapter when used on the pc, which does me no good lol.
At any rate If you do not have a Micro SD card, maybe my process will help someone do a clean install at least.

I hope a solution appears. I just upgraded from cyanogenmod 4.4 to katkiss 6.0 today, and have the same problem . microsd was there for the install, but after booting, ES file explorer doesn't see it. Can see the usb drive plugged into keyboard, but not microsd. frustrating. was thinking of trying to reflash everything but what I am reading in this thread, it seems like that won't help. (btw, there was also issue of tf300 not rooted after install. I reflashed superSU, and after a few reboots and attempted binary updates, suddenly root appeared. I don't know really what fixed it)

What version of TWRP are you running? .... I also had a problem at first with root, but none since and I have flashed every katkiss rom and my back up of JB 4.2.1 and even the fresh stock Asus JB rom with no success as of yet. But I have yet to stop messing with it, going to keep on til I break it, fix it or possibly shoot it. lol
Also, mine still does not work at this time. I actually went online with lj50036 and went through lots of force load commands etc etc and it still never showed up. Crazy thing was at one point it was showing I has 2 Internal Storage folders both with the exact same file size and files within it. I suppose there is a possibility that the card slot stopped functioning in my tablet, but I just keep coming back to my original issue before the card disappeared (corrupted file partitions). I don't know why, but I just feel something somewhere is still fubarred with the file partitions dealing with external storage. Plus with all the research I have done on the issue and such close to it, there seems to be an issue with happening with many devices and custom roms and recovery.
I wish you luck and if I do find a solution I will most definitely post it here.

Issue solved:
Turns out one of the SD Slot connecting pins was broken in the back of the card slot. Oh well, at least it's a 32gb tablet.
Many thanks goes out to Josh lj50036 and the others who tried helping me.

I installed (4 th install, 3 with 6.1) kat kiss naugetella, 7.1. microsd card is now seen. I have no idea what was different about this install other than the 7.1 and different supersu, version 2.79.
still not having keyboard recognized during sleep. previously I could wake the tablet by hitting the keyboard sleep key. No more. have to use the tablet power button.

o3d goes into recovery mode every time it boots

Hi guys, i'm in desperate need of your help. i think my precious o3d might have been screwed.
first let me tell you what i did. as you know the internal sd card of o3d is 5gb or so and it fills up very quickly. this internal sd card is mounted as /sdcard. i have a class 10 16gb micro sd card and when i insert it, its automatically mounted as /sdcard/_ExternalSD. The applications or games, especially the ones that have external data folders which are like 1gb in size insists to be installed on /sdcard. You can't move those data folders to _ExternalSD, because then the apps doesn't work.
Then i came across this topic:
http://forum.xda-developers.com/showthread.php?t=1189701
As you can see that was exactly what i needed. I had CWM 5.0.2.0 installed so i downloaded the first .zip then copied all of the files and folders excluding the _ExternalSD folder to the external sd card then rebooted into recovery. From there i flashed the zip and rebooted again. phone booted up and all was ok and it worked. now the phone sees the external sd card as the internal one and the internal sd card was mounted as /sdcard/_ExternalSD. I then formatted the internal sd card from the settings menu because i already copied all of the stuff there to the external card. It worked fine and the internal card is formatted. After that i decided to get a nandroid backup so i opened the rom toolbox program. From the menus i selected the backup option, gave it a name, clicked ok. the phone rebooted into cwm recovery screen but nothing happened. then i noticed something was not right because there was some error lines under the cwm menus saying "E:can't mount CACHE:recovery/command" etc. Then i selected the reboot phone option but the phone rebooted right back into the CWM recovery again!! At that point i knew that i was @#?^ed.
Anyways i researched a lot and came across this thread:
http://forum.xda-developers.com/showthread.php?t=1156549
i did exactly what he said and it worked, i mean it flashed nicely. then i rebooted the phone but it booted into the recovery again!!! But this time the CWM recovery was gone and i believe this is the stock recovery screen. I can browse the menu of it and make selections but the phone boots into the recovery every time it reboots.
The recovery screen looks like this:
http://farm8.staticflickr.com/7010/6654644033_b616bc0635_z.jpg
Then i flashed the phone to the latest official firmware V21A_00, it flashed nicely but it still boots right into the recovery everytime.
Then i installed the Android SDK and tried to push the original vold.fstab file to the system using the adb command line tool but it doesn't see the phone. I think adb works only when the system boots up normally, not in the recovery mode.
I don't know if there's a way to install the CWM from the stock recovery somehow. If you know how, please tell. The CWM has more options.
I don't know what else i can do. It started to look ridiculous. If there are any experts cool enough to help please do so. I'll be waiting. Thank you...
Edit:
I also tried this:
http://forum.xda-developers.com/show....php?t=1244490
I starts just fine but get's stuck on the "RESET" command, after a while it gives "DOWNLOAD FAIL!" error. I think the phone is supposed to restart automatically but it doesn't. Manually resetting the phone doesn't work either.
I'm about to pull my hair out...
Edit 2:
I also posted on the official LG Mobile forum here:
http://www.lgforum.com/forum/boards...d-goes-into-recovery-mode-every-time-it-boots
Fingers crossed
Quite a post!
From all your post there is no mention that you formated and did a factory reset after 21a flash.
Can you please try that if you haven't?

thank you for the reply!
i tried all 4 wipe options on the recovery screen then rebooted. it's the same, i'm back at the good old recovery again
Did you try with the external sd card out?
This is strange, usually a kdz flash coupled with a format fixes the problem.
Some how it still can't find the internal SD card.
I don't have further recommendations. Sorry

Hopefully someone else on this forum can suggest a way for you to unbrick.
your problem is although you have reset your phone, somehow it can't find a partition to boot from.
or
somehow the KDZ flashing is not totally successful.
good luck
If only there could be a way to be able to use the adb command from the Android SDK then i might be able to restore the vold.fstab file to its original, if the problem is that at all. Maybe then it'll work. To be able to flash the CWM Recovery again somehow might be a good thing too because it has more options like flashing .zip format roms but i have no idea how. Does anyone know if the stock recovery can flash some specifically named file to the system, does it have that kind of functionality? I'm desperate, please share your thoughts.
.............anyone?
I am sorry to say that but there is no solution for this problem yet. I have done the exact thing that you do and tried every single solution with no luck. The only way is to send it to lg repair service. My solution was to replace the mainboard.
Dostum gecmis olsun malesef tek cozum yolu anakarti degistirmek. Uzaman sayilirim android konusunda bosuna ugrasmayasin diye soyluyorum. LG servisi bile anca anakarti degistirerek cozum sunabildi. Temel problem internal karti formatlamis olman. Partititon table'i bozuyor bu islem malesef ve bu yuzden hicbir yontem ise yaramiyor.
Gecmis olsun tekrar...
so you say that the main problem was to format the internal sd card? well if formatting the internal sd card bricks the phone then why the hell is there an option to format it in the settings menu?
well if you didn't apply the swap fix, it wouldn't be a problem to format. When you swap the sd cards and format, it is the problem.

so you did exactly the same thing as me right? i mean you applied the swap fix then formatted the internal sd?
replacing the motherboard to fix this seems to be a bit nonsense to me to be honest. what does the partition table have anything to do with the motherboard?
if only there would be a .kdz format custom rom which factory resets the internal sd card during the flash process and maybe fixes the bootloader somehow, that might be the solution.
yes i did the same and the only solution was to replace the motherboard. we need a sowftware that can reach to the emmc in low-level. like omap flasher. but we also need the correct drivers which doesn't exist yet.

i don't know what the emmc is, i need to do research on that. but i still think that replacing the motherboard won't solve this issue because it seems non relevant to me. i messed up with the vold.fstab file. but after that it worked fine. i mean the internal and external cards swapped just fine. only after i decided to make a nandroid backup using rom toolbox all hell broke loose. i plan to wait a couple of days before turning the phone to LG service. i believe someone will come up with an idea.

Well, there´s a new recovery for the O3D, v5.0.2.7 (I got it with ROM Manager).
It fixes 2 bugs of the previous (5.0.2.0) version: now the USB mass storage option in the mounts menu works (mount external SDCARD), and we can use ADB while in recovery. That way we can fix stuff in the phone filesystem while in recovery: we can now use ADB shell, or ADB push to replace files.
The problem is that I don´t know how to flash it to the phone while in the stock recovery. If someone can guide me on creating a signed ZIP containing this new recovery, flashable in the stock recovery, I would be glad to do that and post it here. I think these phones of you guys can be fixed using this method!

Great news! But now i need to find a way to install the new CWM. Just as you said i believe what i need is to find or make a .kdz update which includes this new CWM.
What do you think?
I know this is possible, at least for the Galaxy Ace: I have a ZIP file for this device with a custom recovery image, flashable in stock recovery!
To make one for the Optimus 3D, I need to know the following:
- How can I obtain the .IMG of the new recovery? I have found some temp files in clockworkmod folder in my sdcard. The creation date of one of them matches the exact moment I upgraded my recovery, and the file size also matches a recovery image: 5.54MB. Is it the recovery image? Can I just rename it to recovery.img? How can I extract it to ensure it´s ok?
- After I get the recovery image, I can use the Galaxy Ace ZIP as the base to build the O3D zip file. Any help on what do I have to change to make it work correctly?

CyanogenMod Woes

Hey all,
I stumbled into an issue a few days ago and I'm trying to figure out how to get it resolved with minimum headache.
I downloaded the latest CyanogenMod download from h8rift's get.cm website, but unfortunately I didn't notice that it was CM9 rather than CM10 until I had flashed it and the boot animation popped up.
I didn't have a CM10 zip saved to my SD card partition, and TWRP, for some reason, would not mount to USB on either my Mac or my PC. The phone wouldn't boot into CM9, so I couldn't download the zip from there either.
So, I hit 'factory reset'.. twice, both from the bootloader, and from TWRP. Well, no luck. Now the file browser in TWRP doesn't even show my SD card's contents, just the TWRP folder. Every time I see a command line in TWRP, it tells me the SD card couldn't be mounted.
So, crap. Are all my files gone? I didn't realize factory resetting wipes the phone. I have all my photos on the SD card partition as well as a somewhat recent Titanium backup, so I'd really, really, really not like to lose those.
I understand that running a RUU will probably fix my issue, but the thing is, on the off chance that my SD card contents are still around, I'd like to be able to keep them. Will running a RUU wipe the SD card, if it still is in there somewhere? Are there any other suggestions re: getting the phone to boot, or be recognized as a USB disk? Also, if I do end up RUUing, I assume I have to unlock the bootloader again. Sigh, that was a hassle the first time.
tl;dr I'm complaining about a lot of stuff that I'll probably have to do anyways because I did something stupid and wasn't smart enough to keep backups, but if anyone wants to give pointers that'll make this process easier I will kiss your shoes and worship you forever.
Thanks.

So I just managed to boot into CyanogenMod 9, without actually doing anything.
So it boots but can't mount the SD card. I have no idea either. Any way to mount the SD card without relocking bootloader?
Have you tried to access your sd card with a file manager app like solid explorer to see if anything is still on the card?

Factory reset from the bootloader appears to wipe the sdcard and leave it in an unformatted state. I did this yesterday and fixed it by letting the phone boot back into the sense rom I was running.
Not quite sure what you can do in CM9. Have you tried connecting to your computer and seeing if windows detects a valid drive? If it doesn't maybe let windows format it, yeah I don't like this idea either, so you can at last get some files on it.
I had a similar problem after flashing a nocturnal update...
Here's what I did to resolve:
Wipe all - SD card, factory reset (all can be done inside TWRP)...then plug your phone into your computer via usb and on your phone in TWRP main screen, navigate to Mount and select USB storage. It WILL show up on your computer as unformatted - just reformat (which will wipe it again) and then let you copy files in. Just download the latest CM10 (which is working great) and flash away...
I am using a Mac computer running win xp via parallels and it worked great - I don't remember what file structure to format the SD card as, but it was the default when it brought up the format dialogue...
Hope that helps!

[Q] S3 Locked in Boot Following CRT Down zip

This is one heck of a way to introduce myself. I am embarrassed and frantic about what has happened. I've been using the guidance in these forums for years, never had any problems, but I usually made a backup. Because of the size of the S3 backups, I didn't have one this time.
I have a Verizon S3 on stock ROM, rooted, CWM Touch Recovery installed, bootloader locked. I flashed the CRT Down - ODEX.zip (attached) from the thread below. Everything seemed to go well, but on reboot the phone gets stuck in the boot animation. I have also contacted Scott over Scott's ROMS since this was where the file came from, but have not heard back. My first preference is to undo the changes to the modded files. Second choice is to flash the latest stock ROM (Stock Root - VRALHE - ODEX.zip) that I have downloaded, BUT I cannot get it on the phone since the phone won't boot, and for some reason CWM does not see any files on the external SD card. My last choice is to do a wipe/restore from stock, and I think I know how to do this, but it will be very painful.
Anyone in a helping mood? I don't know where to go from here. This is just terrible.
http://forum.xda-developers.com/showthread.php?t=1841802&highlight=crt
CWM won't read your SD card because it's not formatted to the correct file system. You could take your card and backup the data, format it to Fat32 then transfer the ROM over to your phone that way. I've long since lost the link to the simple format tool that I used to format my card but if you search for it you should find it in I think the General Forum...
SD card already FAT32, formatted by PC and then reformatted in phone. Thanks anyway.

If you reformated in phone you formatted it back to extFAT.
You are absolutely correct sir. Your assessment was dead on. Thank you very much. I can now make a backup to the external card. Unfortunately, I had to restore the phone (-#*@"*). I found that two other 64GB cards I was having problems with had the same issue. Wow! Twenty five years around computers and I just figured out how to format volumes larger than 32GB in FAT32. Thanks again. This thread is done.

[Q] Can’t mount external SD

Hello folks, yesterday I installed 4.2.2 update (ubranded with MG8 ending, i9105p), everything is working fine, with exception to my SD card.
In Settings -> Storage it doesn’t shows up, and the "mount" button is greyed out, just like no card was inserted. The SD card itself is working (checked on other devices), it uses FAT partition (I even tried to re-formate it) and, since the Recovery can acces (and eventualy flash files) from it, Android OS doesn’t see it. I tried mounting via ADB but I have no previous experience with it. I also tried wiping cache.
I’m gonna try re-flashing another firmware tommorow, I hope it will work. :cyclops:
But is there any easier way to fix it? Thx
UPDATE: The card was working fine after re-flashing, but sometimes when copying files on it, File manager hangs, and files wont copy. This issue also unmounts the SD and makes it unable to be mounted until you restart. Propably some sort of kernel issue? (According to testing and 1+ year of trouble-free expirience with the card on another device this doesnt look like a malfunctionic card)

[Fixed]Need some help

Alright, I've tried everything I could, looked online(/in the forums) for solutions or help, but I just can't figure this out... After struggling a great deal installing the 5.2 update on my K1, I decided to simply flash the 5.2 recovery os image and start from there.
That went fine, so I went to install Magisk to root my tablet, but that didn't go as well. I ran into the same issue I was running into trying to update to 5.2 which is that my storage doesn't properly mount in TWRP (it works normally when using a file manager on the tablet itself and gets detected as it should by the storage manager in settings). I formatted the SD-card I'm using as partially Internal/adaptable storage and partially external, which is probably what causes the problem as TWRP shows the external SD card perfectly, but of the internal storage it only shows the contents of a folder named "InternalStorage' (presumable /sdcard/internal storage, however I can't actually see this to confirm) which is present on the root of the internal SD card. Any files that are in for example my Downloads folder on the internal storage aren't shown in TWRP. I thought installing a factory image would fix this issue, but it hasn't.
In either case, to get around this issue I sideloaded the Magisk zip file to root and it wen't as expected, didn't get any errors. But after booting my tablet, the Magisk Manager app wouldn't finish loading, it's stuck on the flash screen with the Magisk logo. Used the uninstaller and reinstalled through TWRP by placing the zip files on the external SD card and the app still won't load properly. I figure it has something to do with the way I have my SD card setup/partitioned, but I'm at my wits end as to how to fix this atm...
Any help will be appreciated! Preferably something that doesn't include re-partitioning the SD card :angel:
PS: The tablet was rooted with SuperSU before the factory reset, but I'm wanting to make the switch to Magisk because I want to install the Sony Framework to use Remote Play. If there is any other way to install the Sony Framework, using Xposed for example, I can maybe try rooting with SuperSU again.
EDIT: I fixed the issue, turned out the app was installed on the external sd card, moved it to internal storage and it worked!
