[Q]Nexus One can't detect any sdcard

Can someone help me how to fix this problem. Before my sdcard keeps crashing, I just format it and its good again.but now My nexus one can't detect any sdcard. I tried sdhc of different sizes even sd only but still no luck. Problem started to happen when i install custom rom CM7...

Have another rom on card--put there thru pc if necessary
btw does the pc recognize card
if you have a known good rom on card, reformat with sdformatter with full erase and size adjustment on. partition card with 0 swap, maybe 1gb
with card back in phone wipe system/data/etc etc a couple times and flash new rom

Wow, reading comprehension test fail. Dude's phone does not recognize any SD cards he throws at it.
OP -- let's hope beyond hope that the problem is not hardware but software, something to do with the new ROM you installed. First, remove your SD card and reboot into recovery (if you don't know how to from within the OS, then just do this: 1) power down; 2) hold volume-down and power until you see the phone turn on; 3) choose recovery (either clockword or Amon Ra, if you have CM7, right?); 4) wipe data / factory reset). If it still doesn't work...you might be out of luck. I don't think you can actually flash a ROM without using an SD card...even manipulating the recovery through ADB requires that the ROM be located on the SD card.

I understood what OP said--
I am saying start with fresh card and then fresh install of different rom
I am not sure if he can get that far based on his comments, but I would try.
Can you still boot into recovery with no sd card? If so, as mentioned, do that with new rom on card, then put card in phone and mount it thru recovery, then flash rom after wipes.
Don't have a solid answer just options.
I have done every crazy thing I can think of to get phone back up and running and sometimes wasn't sure which step actually fixed it. Just that somehow I am still in the flashing business.
Definetly wipe system also------I do ALL wipes 3X--just my preference
And correct in that no SD Card, no place to put rom on N1
Hope you get it working Unleashed24

[Q] CM10 and AOKP - Internal, SD card and USB storage mapping broken

I've got a Samsung Galaxy Note n7000. I've hopped around a bit, but recently I've tried to move (back) to JB based CM10 (nightly) and also AOKP (JB Milestone 1).
For both CyanogenMod and AOKP, I quickly came across the issue that most apps can't see any storage folders. This includes:
-Browser and Chrome can't save files as there's 'No storage'.
-Google Maps won't cache anything.
-The camera and gallery won't work because they can't see any storage.
-When I plug the phone in to a PC via USB, the phone is identified, but no storage folders come up, regardless as to whether I'm using MTP or MS.
-In the system settings under storage, it can see the 2GB for my app Data partition. It says there's a 32GB SD card available, but under the Internal Storage heading, clicking 'Mount SD card' flashes up something in the notification bar before looking like nothing happened. There's nothing about the internal ~10GB partition either.
However, if I go into a file browser, I can see both the internal storage mapped as /storage/sdcard0 and the SD card mapped as /storage/sdcard1. I believe this is how JB is now mapping storage now? Why is it confusing itself?
Note:
-I can see the storage in CWM without issues (although internal and SD might be reversed???).
-I can read the files fine from a file manager, so there's nothing wrong with the SD card as far as I can tell. It works fine in an SD card reader too.
-I tried AOKP first after a full wipe (factory, data, davlik), hit the issue. Tried CM10 which was the same. Tried AOKP again with a factory wipe before and after flash and it still didn't work.
I've been trying to find a solution for nearly 2 weeks now! Please help before I give up and flash back to a Samsung based ROM!
For history:
I've had the GNote unlocked for a while and I've played with a few ROMs including CM9, earlier releases on CM10 without any issues. For the past couple of months I went back to an ICS TouchWiz based ROM as I thought the only way to get an MS Exchange email email app with full device encryption was to use Samsung's.... anyway, found an app that'll do it for me without suffering the slow down of encrypting the whole phone AND putting TouchWiz on, so I thought I'd try to go back to a 'pure' ROM until I ran into the above problem... Is it because I previously had the phone fully encrypted? I can see the folders now though.... AAAARRRRGGH!

...
Just in case it was an issue that has been fixed recently.... I tried ParanoidAndroid for the Note (v2.54 10 Nov 2012)... same issue. I did a factory reset, cache wipe and davlik wipe before and after flashing. Still both internal and SD storage are mapped so the apps and System settings can't see them.
What is wrong?

Update 2...
I tried flashing the following ROMs:
-A TouchWiz based ICS ROM (Sweet v5)
-A stock based ICS ROM (CM9.1)
-A TouchWiz based Jelly Bean ROM (Rocket Bean V2)
-Re-flashing CM10 nightlies
In every case both the internal and SD storage can't be seen in System>Storage.
What have I done???? Have I somehow screwed up the formatting on both the internal and SD card, yet CWM can read it??? Any ideas?

im on a XXLS7 based rom and its in
/storage/extSdCard
/storage/sdcard0
may be you want flash a stock GB or ICS rom again using Odin and start fresh

I haven't tried Odin yet... but when I was about to, I discovered something. I installed Titanium Backup. Instead of complaining I didn't have any storage (like all other apps), it complained that my storage directory wasn't writeable...
How do I check what the permissions are? What should they be? How do I fix it?!!!
Thanks.

Hi!
I have the same issue.
I'm currently on RocketRom V3 but I had the issues with others roms before.
I have a temporally fix: using root explorer, set the permission from r/o to r/w for the folder /mnt/sdcard
But after a while (fews minutes), it turn back to r/o, I don't know who/why.

Same here. Thought it was me!
Started when I switched to jb leak.
Says storage us full when I try to open camera,etc, even though it's not true
Sent from the man hiding in your attic.....

Ok, I found an fix that works for me
It looks that I had a bad file/folder/whatever on my internal storage, so the system put /sdcard (internal memory) on read only as it notice the bad thing.
Formating sdcard or emmc from cwm didn't work, full wipe neither, formatting internal from android settings neither, but I manage to mount internal SD on my computer using mass strorage (UsB switcher is included on Rocket V3 to switch from MTP to Mass storage)
Once mounted in Windows, I did a full format (fat32) of the internal memory, and so far it works!

I re-formatted my SD card in a memory card reader. I've put it back in the phone and now when I plug my phone in to my PC and select USB mass storage, the SD card comes up in Windows and I can write to it! Woot!
At the moment I still can't write to my internal storage (which means most apps still complain). It appears as a drive in Windows via USB, but I can't open it. I'll try Feyris' RocketRom suggestion later.
Any guess as to why this has happened? Anything to do with the fact I had full-device encryption on the phone before????

Is there any way to sawp the card location as on im on jb its taking external card as internal default location..As i am having class 4 sdcard so itz slowing down the system

When I put my Rocket V3 into the mac with usb switcher it mounts two drives. Both, however, are part of the internal SD card. It does not mount the proper external sd card. One is titled sdcard of the drives just called sdcard, the other is called storage (which has folders sdcard0, extSdCard, and usbstorageA-F). Should I format them both? Do I need to recopy all the files back onto the sdcard before booting up again?
Thanks!
Edit: I was either totally confused (most likely) or somehow I managed to fix my issue (less likely)...so I am ok now.

Internal Storage Mount
So I am having a similar issue.
I have an Evo 4g LTE running CM10 (cm-cfX-20120904-OFFICIAL-jewel)
I tried upgrading to the 11-13 build from get.cm site. I factory reset, wiped delvik, installed .zip from external sd card, installed gapps (gapps-jb-20121011-signed) wiped delvik again, rebooted, everything came up like it should, but I had no mobile data connection. All of my settings said unknown. So I rolled back to the (cm-cfX-20120904-OFFICIAL-jewel) build. Everything was working fine again, except I went open CWM v 5.8.3.5 from my app drawer and noticed message "you need sd card to run clockworkmod" so I went to sys settings > storage > internal storage (not mounted > mount storage and it attempts to read the data, but then does nothing. No error message or anything. I can't get my computer (windows 7) to read my internal storage so I can't format (which I have already done before)
I'm getting really frustrated as I have searched everywhere for the fix and have found nothing. If anyone has any idea I would greatly appreciate it.

Finally got around to spending a few hours on this yesterday to try to fix my 'missing' internal storage...
As suggested by nokiamodeln91 (cheers mate), I used Odin to go back to a stock ROM. Steps:
-Did a CWM backup of my current my current favourite ROM (I also used Titanium and SMS backup, but didn't need it in the end).
-Found an appropriate Samsung factory ROM. I went back to 2.3.6 as it's supposed to be safer. (For the n7000, make sure you choose an early one and not 'L' series or it's harder to root.)
-Used Odin to write the factory ROM. Note I only wrote the ROM, I didn't flash the modem, PIT, etc.
-Confirmed that I could see both my internal storage and my SD card (and also confirmed that a factory fresh install from Samsung looks and feels as ugly as I remembered).
-Used an 'update' hack to give me root.
-Installed CWM again.
-Simply restored my CWM backup of my favourite ROM...
In reality I went down several dead-ends... but I eventually got it all working again.

Dude! you are insane...Got my S2 4.1.2 working, thanks to you.. tried for 3 days back to back until i stumbled on your solution.
Thanks so much.

A BIG Thanks to Guigsy & nokiamodeln91
Long story short is I broke the screen to my GNote 2 which is on its way to Samsung for repair (A little under US$200 round trip). When I removed the battery to get the emie number there was "goo" oozing out the back from the screen I suspect.
Anyway, turned on my GNote 1, which hasn't seen the light of day since last October and booted to discover that it wasn't working right. I tinkered for quite an embarrassingly long time to where I found myself in the same situation as others here. No write access to the internal storage on my CWM rooted GNote.
Although I had a nand backup, I ended up using ODIN to flash LT4 Germany, lost root as a result. went back in to Download mode and used ODIN to install PhilZ-cwm6-XXLT4-OXA-5.00.5.tar the exact same way, booted into CWM recovery and flashed PhilZ-cwm6-XXLT4-OXA-5.00.5-sigend.zip and was good to go. Issue definitely resolved.
I did not have root after installing the PhilZ-cwm6-XXLT4-OXA-5.00.5.tar via ODIN but I was able to enter CWM recovery where I then installed the ZIP version. As I had fixed my issues I was able to copy over the ZIP version to my Ext SD card B4 going into recovery mode (Yup, one of the symptoms for me was not being able to copy to the external SD card when the phone was connected to my PC either).
Rebooted signed in and was quickly synching my apps, settings etc. I would have felt comfortable using the nand backup I had originally but since this solution brought me up a few versions of Android, I just did a fresh setup.
Had it not been for XDA and our friends here, I would have formatted, factory reset and who knows what else trying to fix this.
Thanks much,
Claude H.

[Need Help ] SD card partition unrecognized.

I have a problem. I have a 4GB sandisk sd card. Yesterday when I was on stock DDKQ8 ( with other apps installed ). After flashing cwm, I partitioned to have 1GB ext on my sd using cwm. Partitioning took unevenly very long time. But after completion, I connected phone to pc & on opening easus partition manager, it did not read any partition on my sd. I ran the partition recovery wizard but with no use. I tried resizing the primary partition ( now it was reduced to 2.67 GB ) but the option was grey ( unavailable ). Then I disconnected phone & flashed sgs2 rom. But during wiping, when I opted the wipe data/factory reset option, my phone got stuck at formatting sd-ext. I took out battery & tried repartitioning sd card via cwm. This time it was a bit faster & I got through the wiping quickly & flashed the rom. Flashed d2ext+ & rebooted. In storage option under settings, I found that my internal memory was successfully extended. I was able to install apps & everything was working normally. Thinking that my sd was back on track, I reconnected phone to pc just to verify that the partition was recognized by it. But to my surprise, easus still showed no partition. Now I'm stuck. How do I delete the partition without having to see it ? Will my sd be permanently restricted to reduced memory ? Please help.
Some additional info :
A couple of days ago my friend had brought a pen drive which contained some important files. On connecting it to my pc, windows asked me to scan & fix. I did, but later on data transfer to/from it got really slow & I saw that windows explorer wasn't responding. As he was from the neighbouring town, we couldn't afford to lose the data & somehow after random connecting & disconnecting, I managed to copy the files onto my pc. I formatted the pen drive but the slowpoke problem prevailed. And now I wonder if this in anyway has troubled my sd. Doubting this, I formatted my C:/ drive & reinstalled my windows, in case there were viruses. But the problem was still the same. Thought there might be viruses in my backup files. Ran a boot time scan using avast! for over 2hrs. Found a couple of minor pups. Deleted them & rebooted. But still the same. Unrecognized ( not shown at all, just the primary partition is being shown ) partition by easus. All the drivers are definitely correctly installed by me. I tried copying files to another sd of mine. Even this was awefully slow. Can anyone help me out ?

you can cwm partitions by wiping data and other things.
I recommend you to use mini tool partition wizard to make partitions

I already know that but thanks for replying anyway ! I some how managed to get back my sd to its full capacity but the data transfer from pc is extremely slow ( just 24kbps !!! ). I tried this on another pc but same result. So I'm sure it should be the problem with the sd itself. I had a 5 yr warranty on it. Will I get a replacement ?

Can't mount internal SD Card after installing Albinoman887's 1/12/14 KitKat Rom

So I have installed several versions of this ROM since it began, however when I upgraded to 1-12-14, all went well except my internal SDcard will not be recognized. This means I can't use the camera or Titanium Backup, etc. However, I can see and use the external sd card w/o any issue. Upon every boot I get the icon saying that I need to format SDcard0, but it never completes, only soft reboots and the icon is gone until the next full reboot. I flashbooted boot.img twice after doing a FULL wipe. I have tried reinstalling 3 times doing FULL wipes every time, still get the same. When I boot into recovery and try to wipe SDcard, I get an error saying
can't mount /dev/block/mmcb1k0p36 (Invalid argument)
Error mounting /internal_sdcard/!
Skipping format
I have also just tried the new 1-15-14 build and get the same results. I have fastbooted the boot.img each time. Please help. I have installed many ROMs on this device before w/o ever an issue. What did I do wrong and how do I fix it? TIA!

Reboot recovery
Mount USB storage...
Plug phone into computer...
Let windows format corrupt partition...
Profit

Just putting another method which worked for me (one time issue and fix, so it's a crap-shoot). I don't have the luxury of connecting to a computer via usb for anything except charging.
-properly flash a sufficiently different ROM (I had kitkat, so I flashed ICS)
-start ROM up, check if fixed (mine was not)
IF NOT FIXED, CONTINUE
-mount the SD card in your recovery (mine is WCX recovery)
-reboot your phone into the ROM
This method worked for me. I saw in a different forum that when this happens it's usually because a file that describes the partitions gets corrupted and that because ICS and GB partition the SD cards and internal storage in a different way than Jellybean or Kitkat, that flashing a different ROM (if problem is on ICS/GB, then flash KK/JB, and vice versa) will force an overwrite of the file in question.
This is not as easy as rignfool's method, and once my charge port arrives in the post, I will abandon this method and use Windows to repair the partition like a sane person
Also, it seems like all my media on the internal storage has been wiped, but wutevr :/

Might want to try a newer build where that bug is fixed.

If this is directed at me, this happened after I installed the March 17th or 18th nightly (put a new one on every once and a while). And to be completely fair, I had accidentally selected factory reset in hboot (thought it was highlighting recovery, boy was I pissed).
The problem (or so I've read) with installing another kitkat/jellybean ROM is that the SD card is mounted the same (/storage/sdcard0, and external SD is only /storage/sdcard1) as opposed to ICS/GB (I only remember that you access external SD through /sdcard/ext_sdcard or something to that extent). Only when the SD cards will be mounted at differing locations will the system re-write the files specifying mount points.

Re-flashing a ROM Question

I just have a quick question. I have a Samsung Galaxy Exhibit T599n and running Beanstalk 4.4+ rom. I am having a few issues with the rom after a few month, such as random reboots, issues with PC connection (Phone only runs in Charge only mode, and phone does not pop up the option to use charge only, camera, or media mass storage modes when I connect to PC) and also no longer connects to Kies.
My question is, if I re-flash the SAME version of the rom that I have installed (I have the most recent version) over the current version I have installed, will I lose my apps and settings? Just want to know what to prepare for if I reflash. Should I do that and get to keep my apps and settings? Or is a factory reset necessary to fix my errors?

Do a factory reset that should do it .. if not it might be hardware problem.
EDIT: You can use Titanium Backup if you have root acess to backup all your apps.

Excellent, thank you.
One other question, I had a problem with this last time I did a factory reset. I have my SD card partitioned to install my apps on there (Phone only came with 1GB internal, and would only hold a couple apps) so my SD card is 32GB, with 8GB partitioned to install my apps on. I remember having trouble with them last time I tried to flash a new rom and ended up having to reinstall Beanstalk from scratch and completely wipe the app partition as well.

Ok soo if i understood , you rom that you gona flash on your 32 gb sd card and flash from that also you can get app link2sd i think its called which let you transfer apps to sd card, correct me if i am wrong.
Code:

I already have it set up that way. I have the rom installed, I have the 2nd partition on my SD card, and have the apps linked to it with Link2SD. But, I last time I tried backing up roms that were installed on that partition, I have a bounty of issues. When I went to reinstall the apps, the files were still on that 2nd partition, there were dormant files left over everywhere, so when I'd try to restore the apps from backup, I got a plethora of errors and the rom began crashing. Just wondering if there's any way to backup and use roms that are installed on that 2nd partition using Link2SD?

I see, well since you have only 1 gb of internal storage for use i dont think i can help you with that.. because backup itself take a lot of space and not sure if you can make it to backup on your 2nd partition.
Or you can try transfer your backup files to your PC/laptop and delete everything then ty doing it and transfer back to phone after.
