sd0 after root cant write,normal? - General Questions and Answers

Have just rooted my G300 and discovered the cyanogen mod 10.1 for for huawei ascend G300. I'm amazed at the performance of the phone now, its like errrr a completely different phone! I have also installed PurePerformances™X_CM.1.4 which has made it even smoother. Result.
My only problem now is no software apps or browser can seem to use the internal sd card as a download location.
Namely Marvin spectrum emulator for example says "cannot access /storage/sdcard0/marvin.
But also UC browser and other apps are having trouble with the same location.
I can browse in file manager all the files on there. Quite frustrating .
Is it something to do with permissions, cant seem to find a fix on search.
Any ideas folks.
Once you root your phone is it normal for sd0 (internalcard) to behave this way?
Thanks.

sorted it, the problem was, I didnt follow the instructions correctly to fullywipe phone before installing CM10.1
in CWM.Must wipe and format system cache, do a full wipe (tutorials on here somewhere)
now i see internal storage and external storage (instead of three locations?!?!) and its all working good.
:highfive:

[Q] Please help urgently LG Optimus 3D and Atrix problem

Hi
I had an Atrix and used it for three months, then the internal memory (SD area) seemed to corrupt - I could not format or unmount it or access anything in there apart from copying files with Astro or ES File Manager. Even a full factory restore of the phone did not delete any of the data on the Internal SD (or Media Area). Ended up getting rid and getting an Optimus 3D.
Now, had the 3D for a month and can't believe I am having a similar problem. Android market apps kept disappearing on boot up (this is what started before), and randomly they would be there or not on each reboot. I moved some files using file manager from the internal to the external SD to create some room and my phone got stuck in a boot loop so I had to remove the battery and external SD for it to work again. Then, all of the apps on the internal sd instead of their icons had the android sd symbol and when clicked on say 'application not installed on phone'. When I look at the Sd and memory storage, the internal SD is nearly full still! I can't access it, can't factory reset it, or delete data. Surely there is some way of sorting this without yet another handset - it's gotta be a fixable glitch? In desperation rooted phone with Superoneclick which was really easy but doesn't help me because I can download from the market, etc, but can't actually install - I am stuck in the install 'candybar' for ages and it just won't work. I thought of manually deleting all of this stuff but I can't get a file manager onto the phone and the factory reset wiped out ES and Astro, I can't get them back on in the usual way.
Because I have root access now, I presume I may be able to use ADB through my PC to sort this problem - but of course would need exact commands etc, on how to do this through the command prompt? I am not an expert but think I just need to get rid of the carp on my internal SD which must have a corrupt file somewhere. Please help urgently, it is frustrating beyond belief and I almost feel like going back to Apple!!!!

[Q] Unable to locate internal sdcard error

Hello All,
I wanted to post this to the Android Development section but since I have fewer than 10 posts I am forbidden from doing so.
Intermittently I will notice some apps do not load images or act as they normally should, and upon opening Solid Explorer to do some investigation I receive an error message (Cannnot browse to "/mnt/sdcard". An unknown error occured.). I find I am unable to access the internal sdcard through Solid Explorer, and when navigating using Root Explorer it only displays an empty folder.
This seems to happen at least once a day, and restarting my phone usually fixes it at least for a few hours. Sometimes ending all applications through task manager & clearing RAM memory through RAM manager will allow me to normally browse my internal sdcard using Solid Explorer for about a minute or so, and then become unaccessable again. Phone reboots seem to be the only fix, albeit a temporary one that only lasts a few hours.
I am unable to save screenshots when this occurs, unable to save pictures, some apps do not function properly -- all which makes sense if the phone is really unable to access the internal sdcard. I have performed numerous wipes (full wipe, cache, dalvik) & reinstalled newer nightly SynergyROMs but I have been unable to fix the issue. Searching these forums has not brought me any relevant information which pertains to the same issue I am having.
I appreciate any help or insight you guys can provide, thanks for taking a look.
Quick Background:
32GB Samsung Galaxy S3 on Verizon network
No external microsd card
Unlocked & Rooted
Running SynergyROM Nightly (r73)
CWM-based Recovery v6.0.1.0
Why would you think to post this in Android Development? This is a question, and thus belongs in Q/A (where it is posted). Android Development is for people who actually developed something, like a ROM, Kernel, etc.
I don't know what kind of advice to give you though, besides try formatting in advanced options of CWM, a reprovision (*2767*3855# ) on stock (back up everything first, to somewhere other than internal SD as it will be wiped) or maybe a 32GB PIT, with a PIT being the least likely solution.
I second this question!!

I logged in today because I am having the exact same problem. Same ROM as well, Synergy r73. I've tried formatting the SDCard, tried a complete reformat of the phone. But nothing seems to help.
Also, to clarify, it isn't restricted to the external SD card (which mounts to /mnt/etxSDcard folder). It's the entire /mnt directory that hangs. I'm able to go into options and mount and unmount the external card fine. But as soon as I try and access /mnt using any app (andExplorer, Wifi File Explorer, even a simple 'ls' in terminal) the phone hangs, stops responding to button presses, and eventually reboots itself.
Also, I've found my timing matches Kenshingtx's as well. If I reboot the phone, I can access external storage, and the entire /mnt folder for that matter, just fine, and it stays this way for about an hour or so.
Any further ideas are greatly appreciated.
btw, I think he mentioned posting the Android dev because there is a thread specifically dedicated to this ROM with numerous questions and answers in it. (Albeit hard to follow since it's over 800 pages) I already searched in there and found no mention of this issue.
The SD card problem sounds like something that used to happen with the old modems.
Go to about phone and check your baseband. If it doesn't end in G7 or HD then you have an older radio that had this issue.
Here's a link to where you can get what you need that explains everything better then I could.

My phone has the G7 modem in it.
Thanks for everyone's input so far. My baseband ends in F2 so I'll try updating my modem and see what that does (even though nerfage seems to be having the same problem with the G7 modem). And you're right, I wanted to post in the synergyROM development thread thinking the problem might've been specific to that ROM.
I'll also look into reprovisioning on stock rom per Zalithian's suggestion to wipe the internal sd card, and see if that helps.
@nerfage - I dunno what the problem is then, could be ROM specific. If you figure out what's wrong post how you fixed it here. You may also want to try flashing the HD rom. Might fix it, might not.
@Kenshingtx - Not sure if the wipe would help so make sure that's an absolutely final thing, googling around is always useful. Hopefully the flash thing does the trick though.

Flashed the latest modem ending in HD, and tested my phone over the weekend. Still having the same issue where the internalsd becomes unavailable. Wondering if the hardware in our devices are faulty..?

My phone appears to be fixed. I backed up all the files on my mnt/sdcard, performed full/cache/dalvik wipes, formatted internal memory through recovery, flashed the rom again (decided to try Beans ROM this past week) and I haven't had the same issue come back. It looks like the cause of the problem was something on my internalsd, try formatting it (after backing up any files you need) to see if it'll fix the problem for you too. Good luck.
Note: the fix does not appear to be related to the ROM, i was having the same issue on the Beans ROM as well until I formatted the internal memory

[Q] CM 10.1 internal memory low

I have installed CM 10.1 in my GT-P3113 and it works great, I like the interface better than Samsung. But the internal memory shows up as about 4.5gb with 500mb used by apps, and about 400mb free. That doesn't sound right, I don't have very many apps, but I am having trouble downloading some of the larger games, like Asphalt7. Can I do anything to fix this? Am I missing some step, like a nand flash or format? I have a 32gb sdhc card but use it for music and videos. Don't want to start moving apps to it.

now does your device initially had 11.85 GB internal memory?
if yes, then you could free up your memory.
well, i am just sharing my experience with CM 10.1 on tab 2 but p3100(almost same as p3113, with extra calling facility). b4 flashing cm10.1 i had some 7 GB internal memory with my stock ROM(4.1.2). if i would ve flashed that stock rom again, then my internal memory would ve gone to around 10.9-11.2 GB, as it formats the device completely.
but when i flashed with CM 10.1, i had internal memory less than 7 GB now, it is just because it doesn't formats your device, but removes your installed applications. let me explain you in other way---->lets go with installing windows 7 in your PC.
if you install windows without booting by using some virtual disks or some DVD, your old programs gets stored in windows.old folder, the same happens here, its just that you are using the CM recovery as your virtual disk thing, it overwrites your systems keeping your old files(BUT NOT IN ANY SINGLE FOLDER) they are kept as it is. the apps you installed earlier with your OLD FIRMWIRE WILL NOT GET REMOVED, BUT ALSO WILL NOT WORK.
in this case the only way to get rid of this memory issue is to remember those folders where your programs get installed with yous OLD OS(firmwire) and DELETE them directly(just like deleting WINDOWS.old folder if you dont need it). well for some huge games like NFS MW or ASPHALT, dont delete those folders where it got installed previously, as these are downloaded data, so with your new firwire you just install the game with the reqd apk file and your game will run without downloading data again, if you delete them, u ve to download again. but its better if you keep a backup of such huge games in your PC)
but in the other way if you install windows from the boot using your DVD, you ve an option to format and reinstall(the formatting drive option, you ll not get if you are not booting from the CD and directly running the installer from within an OS). the same happens here too, if you flash your firmwire from the download mode, your device is completely formatted(additionally u may need to clear wipe cache/wipe dalvik cache too, from the recovery).
SO IF YOU FLASH CM 10.1 FROM THE DOWNLOAD MODE YOU CAN GET ALL YOUR MEMORY BACK, but i don't know if there is any method to install CMs or AOKPs or any custom ROM from the download mode, as these files are in zip format and not *tar.md5. so we install them from the recovery mode.
LETS SEE IF THERE IS ANY METHOD TO INSTALL CUSTOM ROMS VIA DOWNLOAD MODE USING ODIN DIRECTLY(but i dont think so).

[Q] P3110 ...internal sd probs.

Just rooted my new 3110, successfully .......(or so I thought) . Now I cannot install anything on internal SD. Whenever I try, I get "not enough space" error message - even the 2 apps(only had the tab 3 days)! that were on the sd before I rooted, have mysteriously moved to phone memory. I cant even install FolderMount , which I had already d/l. Forgive a newbie, but having rooted my Galaxy W phone 18 months ago with very few problems, was hoping tab would be as reliable. Anyone help? (as I dont want to unroot just to be able to use internal sd memory.) Thanks in anticipation.

I'm confused, how did you get apps to run on your external SD without root? Didn't know that was possible. Did you try clearing the dalvic cache? Seemed to do the trick when i had issues with lucky patcher causing that same error. I may be way off base though.
Edit: i think I'm confused, sorry, that advice is surely off. Uhm, perhaps reflashing stock and trying again,seeing as how you do not have much data to loose, using the auto root Odin flashable file.

...........Thanks for the help.. Wasnt talking about ExtSdcard, but sdcard0, the internal storage -,sorry for confusion-. Although "Install manager" shows all apps as being installed on "phone" memory, & "external" memory empty, both "Disk Usage" & "Root Explorer" show the same files/size used, in both locations, so I now figure I may have partition problems after rooting (I used this system : http://forum.xda-developers.com/forumdisplay.php?f=1596) Will try the auto method as per your link if I cant solve the issue (though hoping a quick fix might be possible.!)

Still "not enough space" issues.
Ok. I tried wiping data, flashing back to stock rom, then chainfires auto - root method. All went well - device rooted (again!) fine, BUT I`m STILL having problems with storage. Some apps (especially games) wont install - am getting "not enough space" message, just as before. It seems that all apps that need to be intalled on the devices internal "sd" (such as" FileMount") card just wont.
Please forgive a couple of lame questions, but having never owned a tab before, I`m new to their "vagaries" - Also I have searched here & other online forums for an answer, so forgive my badgering all you "fonts of tekkie wisdom."
. Mine is the 8gb model, & I know a lot of this is taken up by system/ram etc - the "device memory" reports a total of 4.49gb, but TB (& other root apps like sd maid) states : Rom 1.26 gb, internal 4.92GB, sd card 4.82gb (with exactly the same space used in both , i.e. 1.50gb. I also have 32gb micro sd inserted. - Is there an internal partition for the "sdcard0" space , or it there a "physical" internal sd card ? If so how do I format thhis? If not could I have a partition problem? (The reason I ask is that none of the "move to sd" apps I have tried like app2sd, install manager etc work - They state, apps have moved when they clearly havent.
So I think it may be an internal partition problem, (which I presume hasnt been solved by reflashing stock, and re- rooting.) - I did notice that when I was re-rooting by CF auto root, in odin there was partition check box, but CF instructions said "if, & ONLY IF, device is bricked, to check this box. - So how can I , - 1. confirm whats causing the problem?, & 2. -Solve it?
Thanks for any help & advise hopefully, proffered, forthwith.:fingers-crossed:
do a simple thing! factory reset your tab. click format sd ! these issues are solved just by formatting the sd, be it internal! :good::good:

Its a partition, its an emulated SD card. I think the post above me has the right idea.
Also, none of those apps will work. You will need use a sdcard swap script, gl2sd(app), foldermount, or some root app or script that is similar to those.
I think you will need a custom recovery, (like cwm, or twrp) to format the internal "sdcard", i never really used the stock recovery much, but it seems like an option they would leave out. I think there is an oden flashable in developer section. I would find links for you, but i got to get the kids ready. Shouldn't be hard to find.
If you can not format the internal SD using stock recovery, here is a link to the Odin flash able cwm.
PS. I really do not think it is a partition prob., and i wouldn't click the repartition option.

OK Folks - seems I have fixed the problem, by uninstalling all apps (inc "moving" apps) that dont work or are "buggy" , cleaning/wiping caches/data, then I was able to install FolderMount from here, and now all the instability/storage problems gone. (Am so impressed with FolderMount have bought pro, as I am a bit windy when in comes to T.E`s or running scripts! My 32gb is filling fast enough anyway!)
