[Q] samsung galaxy s2 exynos mem bug - Galaxy S II Q&A, Help & Troubleshooting

i have samsung galay s2, ICS installed on it. instead of showing its internal USB storage as 11Gb , its showing 4.11Gb. i installed an app called
"exynos-mem bug checker". it says "this device is affected by the 'exynos-mem' bug issue".
what is actually the problem ? and whats the solution ?
whats the best way to get my lost memory back ??
m much worried abt it ..because i recently bought it.
kindly reply asap

Never heard of that but a flash or factory reset would do the trick.
Of course you might get bricked if you factory reset on 4.0.4.
Siyah v5 would help you get to the safe side tho.

Bug Is better know as brick bug. You on firmware 4.0.4? Flash with Odin firmware 4.1.2 and you won't have the brick bug. Whatever you do don't factory reset your phone while on ICS. You need to read a lot more if your on that firmware. Sammobile is were you will get 4.1.2 jelly bean firmware. And don't mess up flashing with Odin. Before you do that read :thumbup:

Oh, you're right, I got mixed up with the internal space thing.
I stand corrected, I did hear about Brick bug.

Judging by what you said in the OP, your phone IS affected by brickbug.
Just so you are 100% clear on this......
Brickbug IS a phone killer....no way back from it....as @andrewwright and @gastonw have both said.....DO NOT under ANY circumstances, perform ANY wipe while on ICS 4.0.4.
upgrade to JB 4.1.2 or roll back to ICS 4.0.3 as soon as safely possible.
Visit sammobile for the firmware and use Odin to flash it......but before using Odin, read everything you can find about it.....don't just rush blindly in, or you are likely to have other problems......good luck

The theory behind that idea is sound.....
But......
Flashing a pit file is seen as a LAST resort....
If it goes wrong, it'll have pretty much the same effect as a brickbug wipe.....turn the phone into an expensive paperweight.......

Not certain if this would work, but you could try odin flashing the JB leak test firmware @gastonw should be able to link you to it.......
I believe it formats (and repartitions?) during the flash, so it *could* be the solution you're looking for......somebody cmiiw
Edit.....here's the link.....
http://www.sammobile.com/2012/11/15/i9100xxlsj-–-galaxy-s-ii-android-4-1-2-jelly-bean-test-firmware/
It's a 3 part firmware, so it's not as simple as adding a single file to Odin, but if you read and follow the instructions in that link, you should be OK........

Actually.....just had a rethink about this.......
Here are the 'known' facts.......
1) you WERE on ICS 4.0.4
2) your phone was classed as 'at risk' from brickbug
3) you appear to have lost some storage space.
My (worst case scenario) guess is that you performed some sort of data wipe, and while it didn't kill your phone, it corrupted a portion of your storage. I'm guessing that if you now try to repartition the storage, you'll run into issues where the repartition *could* fail.......and you'll be left with an unusable phone......as it stands, you CAN use the phone, I'd be tempted to leave it that way, and maybe claim warranty with Samsung. Maybe @theunderling or @andrewwright or @gastonw or @Hopper8 can comment on this theory........

Yeah, storage doesn't just go away.
Is there something you're not telling us? If there isn't, contact samsung/warranty.

we've been facing the same issue on s advance while flashing 16 gb version without a specific pit file or checking repartition without one.
if you guys saying its risky on s2 i got that, it was just a clue how we solved it in s advance. flashing firmware with odin and correct pit file solved the memory shrinkage issue.

okay ... let me more clear. i bought it from olx. at time of purchasing i didnt checked the USB storage. later on i realized that its showing less space. perhaps that guy(seller) did something to cellphone unknowingly. m not sure what he did.
PS: its warrenty is expired.
