[LG Optimus Black] N00BY0815:
The problem is, you often dont really know, what new patches will do to a kernel. If you add them and your phone shows no problems at all, like mine e.g. you ll never notice, you introduced a bug. Then you already prepare a new version and then all of a sudden the problems begin to pop up for some users. I hardly had that bug. Where did the bug come from? You can hardly tell... Also it might have been a bug, which LG already had in their code, just that you havent noticed it yet... Always hard to tell. I mean if not even rmcc knows, where it really comes from, it really seems to be hard to debug :P
[LG Optimus Black] morx:
The point is, that some users have no problem at all, so im really catch myself thinking sometimes, "fck it, it surely is the SD card's problem".... which might be true, who knows.... ??

what do you think about that..?
[LG Optimus Black] N00BY0815:
Well since I had it myself already, but veeery rarely, which might also have come from drops :P I think it is a common problem. Also a friend of mine reported several unmounts of his GF's phone.

Found this:

https://github.com/CyanogenMod/geek...mmit/9157ee85a686ca6c7a31a281d7accd8aedfc31fd

Oh I think it was this one: https://github.com/CyanogenMod/geek...mmit/c7d3c335918feff6c26a731f537303ae8cdc63c3

I am not sure if that is the commit he was talking about, but I think it's the only one I found on that git...

If anyone can find something else, that might be related to it here: https://github.com/CyanogenMod/geeksphone-kernel-zero/commits/android-msm-2.6.32

Just add it to the thread and I ll look into it, as soon, as I have time. Maybe also link the other kernel devs here, cause it might be important for us all ;)
[LG Optimus Black] sensei22:
When I started to have unmounts every 30 minutes I decided to go back to GB. Stayed there for a few weeks but for some unknown reason, my phone went into reset bootloop so I flashed it again with ICS which was the only thing I had handy at my work's computer. The only different variable has been that I used a different computer this time and I had the original 4GB SD (came with phone) inserted while flashing instead of the 16GB. Now it has been 48hrs and counting with not a single unmount. Fingers crossed that this not happen again :p
[LG Optimus Black] maludroid:
Great find! This should be it: https://github.com/CyanogenMod/geek...mmit/c7d3c335918feff6c26a731f537303ae8cdc63c3

Firstly probably merged into nightlies, and then on July 26th to main branch.
[LG Optimus Black] sensei22:
So is there any way we can have this piece of code into our V30B stock rom?
[LG Optimus Black] morx:
You feel lucky punk ?!?!? :laugh:

it will happen sooner or later my friend :rolleyes:
[LG Optimus Black] N00BY0815:
Well at home I checked my git and we already do have it in our sourcecode, but it's a bit different, maybe it's that difference, or maybe we also need that difference :p gotta check that somewhen
[LG Optimus Black] sensei22:
I felt lucky...until it happened again a few hours back :(
[LG Optimus Black] morx:
Happened to me too, a few hours ago, and surely will happen again :P

Yesterday happened something more serious, my laptop's motherboard got fried (4 years old)....

....so i wont give a flying f*ck about SD card anymore, if it gets fixed with v30c or whatever future version, let it be, i wont care anymore

it's only a reboot once in a while, sick of breaking my heart for stupid things.

I'm only 800 euros less in budget now (been saving a lot for months) and im happy new owner of a new 17" strong laptop for any use.

Next will be the P970, when it goes dead, immediately replaced with a new one.
[LG Optimus Black] sensei22:
V30C released, do you want to give it a try to see if it helps you? :)
[LG Optimus Black] silenthitman47:
soo

does the v30C still has the UNMOUNT problem?? thank u
[LG Optimus Black] sensei22:
Don't know yet, I am at work and cannot flash it, probably tonight I will find an open slot to flash it.
[LG Optimus Black] N00BY0815:
V30C is basically the same kernel, just the gpu driver has been updated slightly. But those updates are only debugging related, as far as I can tell.

Look at this commit in my git, if you re interested: https://github.com/n00by0815/kernel_sniper-ICS/commit/8e46cb64b66663f58cdff45f15c2fc423c77ccd9#L2L82
[LG Optimus Black] j0ris:
I have this problem now at least once per 24 hours, on Marvel D (V30B). It's starting to piss me off to the point that I'm considering to just ditch ICS until this issue is somehow reported to be fixed.

Again, what steps exactly would we need to perform to produce logs that may help in diagnosing the issue?
[LG Optimus Black] sensei22:
Given that some people have reported no issues after adding the external memory improvements on Pimp My Rom, I contacted the app developer and got this response.

Simply add the lines I gave you to an init.d script.

To guide you in details :

- make an empty file in /system/etc/init.d and call it 98sdcard, either with a file manager or by typing the following in a terminal emulator :

Code:

su

mount -o remount,rw /system

touch /system/etc/init.d/98sdcard

- paste this into it :

Code:

#!/system/bin/sh

# Script to attempt to fix scard random umounts

echo 128 > /sys/devices/virtual/bdi/7:1/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:2/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:3/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:4/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:5/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:6/read_ahead_kb

echo 128 > /sys/devices/virtual/bdi/7:7/read_ahead_kb

echo 4096 > /sys/devices/virtual/bdi/179:0/read_ahead_kb

echo 4096 > /sys/devices/virtual/bdi/default/read_ahead_kb

echo 97 > /sys/devices/virtual/bdi/179:0/max_ratio

echo 97 > /sys/devices/virtual/bdi/default/max_ratio

echo 4096 > /sys/devices/virtual/bdi/179:0/read_ahead_kb

# Values from Pimp my Rom by Androguide.fr

- Modify the values you want (= the numbers after each "echo")

- Open a terminal emulator and type this :

Code:

su

chmod 755 /system/etc/init.d/98sdcard

After that, if your kernel has init.d support, the script will run at each boot.

But for testing purposes you might want to run it manually so you don't have to reboot each time you modify the values, to run it simply open a terminal emulator and type the following :

Code:

su

sh /system/etc/init.d/98sdcard

About the logcats, there definitely is a problem with your vold (/dev/block/vold) module.

Are you building your rom from source ? If you do you could try to build the kernel with "Defer MMC layer resume until I/O is requested" option in the kernel's menu_defconfig, as suggested in the thread.

[LG Optimus Black] sensei22:
Although a guy posted in the general forum that he still got the unmount issue in v30c I went ahead and flashed it (although with no hopes). I will keep you posted.

[EDIT] Just got 3 unmounts in less than 1 hour.
[LG Optimus Black] morx:
That's bullsh!t mate .... i dont even bother anymore about this LG crap, seriously! :eek:

SODs, Unmounts, crappy LG software ...

v30c is out and still there are unmounts? Screw this....
[LG Optimus Black] j0ris:
Is there any way someone here could build the kernel for us with this option, as suggested?
[LG Optimus Black] morx:
a couple of unmounts now and then ....

a couple of "freezing" while navigating through apps

and a couple of new issues appeared.

1) Package file invalid in numerous apps downloaded from google play. I have to try 1, 2, 3, 4 ... etc times to get one updated or installed for first time. Happened in no time, without doing anything on my cellphone.

2) ALL SMS THREADS DELETED . I've sent tonight an sms message to a friend, the next thing was an EMPTY inbox. Completely empty.

Rebooted and still no sms at all... new sms are being stored like nothing happened, all old ones before that, dissapeared.

For fck sake with this.... hands up with this phone.
[LG Optimus Black] maludroid:
Guys - do you still suffer this issue?

I don't - since two weeks. I have funny conclusion, but to share it I need to know if you still suffer it.
[LG Optimus Black] sekhar13515:
well... is this issue solved or not ?
[LG Optimus Black] morx:
No, it's not.
[LG Optimus Black] cphx:
I installed LG's ICS yesterday, V30B, and so far it unmounted once yesterday, and again a few minutes back.

When I had CM10 installed, this happened occasionally, but it seems much worse on LG's ROM so far. Strange issue...
[LG Optimus Black] morx:
i'll go back to marvel V10 (2.3 android).

if that **** happens again (wasnt happening on 2.3) i'll change my SD card with a brand new.

That's the last thing i can do.

if the problem is not resolved, then i'll scrap the phone, sell it for a couple of euros, i wont give a fck anymore about LG dildos.
[LG Optimus Black] sekhar13515:
If u wish to sell

Next try Samsung grand, marvelous features at very low price and freebies
[LG Optimus Black] morx:
Samsung was what i thought about, anytime speaking about replacement. Time will tell....
[LG Optimus Black] j0ris:
I haven't tried it myself, but here is a post claiming that the issue is solved on IZS by manually installing dianakernel 0.2:

http://xdaforums.com/showpost.php?p=38009070&postcount=1221
[LG Optimus Black] morx:
i removed Viber.

No issues since then... i dont know if that was causing the problem, but time will tell....

if anyone has viber on it, try to uninstall and evaluate for some period the results :)
[LG Optimus Black] baddiva:
And, that funny conclusion would be?...

I've got this problem once in marvel v11, very often in IZS v0.3, but this not happened as long as a week in Marvel v11 @ ZGK1.0... Now trying Marvel @diana 0.2...
[LG Optimus Black] j0ris:

I'm on izs v0.4 no changes, interactive and row and haven't experienced sd unmount...
[LG Optimus Black] sekhar13515:
thanks, please keep this thread available forever (don't close), as may this solution will help in future also
[LG Optimus Black] rrgrrg:
Again and again its related to the card not the rom ,, i have never had an unmount on any ics kernel\rom or even cm10/10.1 ,, please if u face this bug copy ur files and format and paste them again :D
[LG Optimus Black] baddiva:
Excuse me sir, what exactly the property(es) of the card that may affect this bug? is the speed of the SD caused it, or it's because the structure of the files on the SD? :confused:

I wonder because I didn't experienced the problem by changing ROM/kernel, without re-formatting my SD... or maybe I will face it in some future... :eek:
[LG Optimus Black] jimakos29:
what a tough luck we have then that when lg released ics most sd cards have gone bad... You can't be serious by saying that all those people's cards have broken down the moment they updated, can you? and miraculously they once again start working properly when they downgrade to gb. It is software related and even if the firmware lg provided has problems cooperating with certain types of sd cards it is still lg's fault. I mean the same sd works fine once i downgrade to gb and even on my o3d with ported ics...
[LG Optimus Black] morx:
Did you read the whole topic or not?

I've spend MANY MANY MANY MANY hours, trying more than just 2 SD cards.

In total by the first time encountered that problem, since a few weeks ago, i've tried more than 8 different capacity, speed rating, brand name microSD's .... problem was still there.

You had NO problem, so i guess you shouldn't be in position to make any assumptions, alright?
[LG Optimus Black] N00BY0815:
AW: SD suddenly unmounts on V30B

Did you always copy the same files to those sd cards? Because if yes, it might always have been the same buggy file, that caused it. I e.g copied all the file (mostly pics) to my pc and deleted them on my sdcard. Since that i had nomore unmounts. Pretty strange though...
[LG Optimus Black] morx:
Every different test SD card was used EMPTY formatted from inside android menu.

It was a matter of time, calls, screen on-offs (usually maximum a day) until the unexpected unmount happened.

Like i said previously on another post, i got rid of VIBER and till then it's super stable without any issue at all !! I'll keep watching it and i trully believe in my case this was the problem. Still monitoring how it goes, no unmounts since the uninstall of it.
[LG Optimus Black] N00BY0815:
One more thing, could all those who have problems with the unmounts try the following:

After you connected your phone and did what you had to do, please remove it safely in windows, then take the phone and change the usb mode to charging only. First then unplug your phone again. If that solves it, LG must have some bug in the mounting process and we know, what we need to look for, or can tell them, where they should look for the culprit ;) Because AFAIK it's not only our phone, that has those problems since the ICS update, but all phones who got that update. So give it a shot and let me know please.

:EDIT:

Also let me know, if you use LG Software Mode, or massstorage mode, to connect to the device.
[LG Optimus Black] morx:
It has nothing to do with USB charging / file transfer.

It's been over 9 months since i connected my via USB with my PC.

I always transfer file by "wifi file manager".
[LG Optimus Black] N00BY0815:
Well that software also has got to mount the sdcard and properly unmount it afterwards and get it back to correct mode. If it doesnt, you will encounter errors. Well that's at least a starting point.
[LG Optimus Black] morx:
No issues using that :D

The only time it happens is when iddle right after a few minutes of a phone call when locking the screen right after.
[LG Optimus Black] jimakos29:
well it IS only ob with the problem. I hav also an o3d with a ported ics rom from the korean o3d and no problems there... My brother also has 2 lg phones (an ob and a 2x) and only his ob does that. Plus I tried what you said above and 3 and a half hours later got an unmount. Btw what is VIBER? and how to get rid of it? Didn't find anything in the stock app manager...
[LG Optimus Black] morx:
Jim, Viber is a VOIP programm, like skype etc .... you use your phone number to register (reads your contacts and matches the results to see which people use it too and show them, to place free internet calls).

I had that programm and figure out that it causes among with some other issues, this one (the SD card unmount) in V30B.

so far so good without it.
[LG Optimus Black] j0ris:
First of all, thanks for trying to help!

But the unmount issue happens to me without connecting to any computer: I reboot the phone after an unmount, and then usually within a day I get another unmount... without having connected the phone to a computer.

Also, I checked, but I already had the phone in "only charge" usb mode.
[LG Optimus Black] jimakos29:
any news on a fix? anyone got a hold on any lg official answer about the issue? not that I am counting on them for a solution, but just wondering...
[LG Optimus Black] jimakos29:
after ten days of quietness boom. 3 unmounts on 5 hours today... Is there really nothing new on the matter? Do I have to flash gb again to have the phone working as it should? Anyone working/looking into that?
[LG Optimus Black] wyrman:
I was having the same problem with two phones. Erased SD card and did a factory reset. Reloaded and haven't had a problem with V30B. Matter of fact I just loaded V30C late night the same way and havent had an issue either.
[LG Optimus Black] yomek88:
Today i saw, that i have problem with sdcard too. I've got sandisk 32gb ultra and i'm on IZS. Everything is ok, but during calls i saw that media scanner is searching for media files... :| strange a little bit.
[LG Optimus Black] sensei22:
nobody is paying attention to try to fix it (as far as I know), I guess we are doomed and will have to start saving for another phone.
[LG Optimus Black] morx:
Who told you we're not already doing this ?? :laugh:
[LG Optimus Black] jimakos29:
well... who told him that someone IS doing it? as far as I know there is this thread here only mostly with people reporting that they have the problem but no thread about people trying solving it or anything. Might as well be this thread for all I care but I see no dev being occupied with the specific problem. Not that they have to ,mind you, but all I am saying is that the notion that gets out is that no one is worried about it simply because they don't have the problem...
[LG Optimus Black] blackcodetech:
What is the complete solution for sd ?
[LG Optimus Black] morx:
No real solution at the moment....

if you're lucky to have no problems then you are.

if you're not, throw this LG bull**** from the window.
[LG Optimus Black] androcraze:
I don't think it's a matter of people not caring. It's probably damn tough to figure out.

I've never experienced an SD card unmount in over a year of daily use with the factory Froyo 10c, and Marvel versions 9,10, and 11. I've avoided even saying anything; I didn't want to "jinx" myself. FYI, I have a SanDisk 8GB class 4 card.

Could be a hardware glitch, could be a particular program of combination of programs. Maybe folks need to post more detail, or developers need to ask for more. I'd want a full system and application listing: launcher, default apps, store apps, SD card model, wi-fi/GPS configuration, baseband... Everything!

Im running Marvel V30b (the first one released) with Europe baseband recognised fully.

I tried TONS OF COMBINATIONS with any type of SD card i have, different brand, different size, different cluster size, formatted through windows explorer, through CMD, through linux, through android menu and so on.

I tried lots of different kernels.... undervolted or not, above 1000mhz stock or not, different governors.

In conclusion though i've need to confirm that, the problem with unmount doesnt occur when im in airplane mode. Need some more time to make it sure.

If you check those posts above, i've been giving tons of feedback about what i've done or not, the problem is, there's not any developer asking about a logcat or giving CLEAR instruction of what he needs to investigate the problem.

The only thing is going on in here, is xLoud, beats audio, bravia engines, different blinky blinky themes etc and lots of incomplete roms.
[LG Optimus Black] androcraze:

Interesting read from another thread:

http://xdaforums.com/showthread.php?t=2190285

Are you using "Live Wallpapers"? I'm not, and I DON'T experience the SD card unmounts.

Would be interesting if this was actually the issue.
[LG Optimus Black] MEC-777:
I started a separate thread about changing from live to static wallpapers (specifically with 4.2.2 ROMs) to see if that reduces or stops random unmounts. It has worked for me. So far not one unmount. (fingers crossed) :fingers-crossed:

Would be interesting to see if the same thing works for those running ICS ROMs...
[LG Optimus Black] panic46:
This is a big problem of v30 stock... LG released a better rom!! :good:
[LG Optimus Black] Michalowic:
I'm using static wallpaper and have SD unmounts twice or three-times per day. I tried IZS by Huexxx, CM10 and CM10.1 and its the same everywhere.. :mad:
[LG Optimus Black] MEC-777:
Static wp from the SD card or one of the stock static wp's? Don't know if it makes a difference, using a wp from the internal vs. SD card... :confused:

Have you tried pulling the card (unmount manually in storage settings then physically pull it out) make sure all the contacts are clean and then reinstall/remount?
[LG Optimus Black] Michalowic:
From the SD card. When I had CM, I used stock wallpapers and it happend too..

I tried to pull out the SD card and then plug it in, and nothing happend. The only solution is restart.. :(

Now I'm going to flash Ultrasound and I will keep testing... ;)
[LG Optimus Black] androcraze:
Try reformatting the card from within the ROM. I've seen that recommended here before.
[LG Optimus Black] Michalowic:
Well, I tried it and after 20 hours is SD still mounted.. :good:

I will keep testing, but this is maybe the solution.. :)

Edit: 48 hours and still not unmounted! New record! :D
[LG Optimus Black] YourMyDinner:
Hey guys. I've been suffering from the same unsuspected unmount issue with the V30B. I've tried this and found these problems:

What I've tried:

Formatting the Sd card ( PC and phone )

Hard Reset

Re-flashing the V30b

Buying a new SD card.

Problems:

I had a 4gb class 6 sd card, now i bought a 8 GB class 10. When I insert the 8GB sd card, past a few minutes it freezes complete. And when i remove the card it restarts the phone.

I've thought of installing a new rom like the 4.2.2. But from what i understood ( attention I'm kinda of a noob on android systems) you need CWM. The thing is, CWM needs the SD card. So I can't use the 8gb one, and with the 4 GB one, CWM freezes when I try to do anything (backup, recovery etc ). So I'm stuck with this.

What sould I do? Flash a new rom? is there any bin files for the 4.2.2 so I don't have to use CWM?

Cheers & Sorry for the long post.

[LG Optimus Black] Sobralobo:
If you want to get a recovery, just follow NOOBY's thread which will explain it well to you. You'll simply have to use SFT, flash a patched V20X... well you'll see. ♬

so still no solution for the unmount problem? anyone at least discovered what is causing it? why this happens to some people only?
