Custom roms and encryption.

Hi,
I have some questions regarding encryption.
Are there any downsides to encrypting an Android device?
What about encrypting SDCard, will CWM still be able to mount and read it?
Last, after encrypting a device is it still possible to update the rom normally through CWM?
Cheers.

If you encrypt your phone, CWM will not able to work.
Backup/restore functions cannot de their job...

Yes.. thats right.

What do you mean? Will CWM be deleted or is it just the rom updating? What about factory resetting in CWM?

CWM will not be able to mount System partition, nor Data. So factory reset option will not work at all...

Oh. OK, thanks!
One last question: is it irreversable?

It let me decrypt my phone... Agreed i encrypted memory area only. But there should be the option to decipher it...
Takes more than encrypt, but CWM will work again as it should do

I'm not quite sure what you mean? How is it done?

Cannot remember... It shows up ONLY if you already encrypted the phone...
Well, i think

Content disappeared after ROM install?

I tried installing CM 10.1 from the newest Synergy ROM today, and all of my gallery stuff is gone, plus all of my Titanium backups. I assume this is because it isn't seeing my internal storage. Help please?

Look under /data/media or even under /0. It's all been moved there bud, due to the multi-user functionality of JB 4.2

Do I move those files somewhere or something?

Sorry, your "old" data is under /sdcard/0. Pretty sure you want your internal storage data that you intend to actively use under /sdcard for JB 4.2 roms. It should be under /sdcard/0 which makes it appear as though its inaccessible on AOSP roms.
More info here and here.
I'm using a TW rom so I'm not looking at this directly in front of me btw.

Not having much luck with this unfortunately.

I moved the files with root explorer as that link says to do, and now there's nothing in the 0 folder, and also nothing in the sd card folder. I don't understand what I did wrong.

Which is weird because I just tried flashing back to Synergy, and then downloading and installing a clean CM Rom and wiping from Rom Manager, and the files still are not there. But they are there in Synergy.

Screenshot where your internal storage data is located presently OR post the exact file path where it's located. And are you sticking with AOSP or TW? For TW, leave your data in /sdcard.
Moving from TW to AOSP 4.2, /sdcard gets moved to /sdcard/0. Simultaneously, it recreates new folders so you'll have empty folders in /sdcard that were rebuilt once you boot into the 4.2 rom. Cut and paste the "old" data in /sdcard/0 to that newly recreated directory once you verify that's where your "new" data is saving to. You can verify by taking a random picture then looking where it's saved to in the file system

Everything was in the 0 folder until I moved it to the root of the sdcard. Now everything is empty.

Hopefully this works. But this is as of right this second on the Synergy rom.
Sent from my SCH-I535 using xda app-developers app

So in /sdcard, do you now have all your folders containing photos, Titanium Backups, and etc? As in, can you access them with the file manager?
Also, does every folder in /sdcard have a "." in front of the name?

I have them, but can only see them in Synergy, and not in CM

Aight, give me like twenty minutes to flash an AOSP 4.2 rom and look at this first hand. Maybe I'm just not understanding how to resolve your problem due to file paths.
But do you want to stick with AOSP 4.2 or stick with TW?

This is my current setup, I'm just trying to go over to the newest nightly build of Cyanogen and this is my only issue. But as I think I mentioned before, I'm pretty sure I moved all of the files in the 0 folder over to the sdcard root this morning, and now everything is gone.

Hmm, did you wipe the internal storage when flashing going from CM to Synergy? Cuz it wouldn't disappear when moving to a TW rom from AOSP since recovery doesn't wipe /data/media unless the internal storage is wiped.
If I'm understanding you, none of your pics/TB backups/etc are in data/media or /sdcard or /sdcard/0 or /data/media/0? It's just empty folders whenever you look in those places?

That is exactly the issue. No problems in Synergy, but CM doesn't see any of it.

How about under /storage do you see an folder titled "emulated"

Screenshot taken from CM and these folders are empty as well.

Unable to factory reset... Wtf?!?!

OK so I got this skyrocket from a friend, but for some reason i cant get rid of his data. I've tried regular factory reset via settings, also I tried flashing the stock ROM with Odin, both seem to work fine, I'm not getting any errors or anything, but when I reboot the phone afterward its still exactly the same, all his apps, accounts, data is still there. I also tried to install cwm via Odin which also said was successful, but then the stock recovery is still on the phone any help would be greatly appreciated, I've had a few sammys in my day so I know my way around Odin / heimdall etc... But this is puzzling

I just tried that right now, still no luck. Also a weird thing I noticed is that when I do a factory reset from the settings menu, the stock recovery menu comes up and I have to manually push the factory reset/erase all data option with the vol rockers & power button... usually its automated when done from the actual settings menu.

Idk, seems you've tried everything I can think of. Weird that returning to stock and then formatting internal doesn't work.

seen this issue once b4, determined it was nand write and/or erase failure, I don't think the guy ever did figure it out . no errors were given when using odin or recovery, no matter what he flashed/erased the phone booted up as if he never did anything.

Yea that's what I was thinking, its like the whole system is set to read-only. Some sort of chip failure maybe. Bummer cause the phone looks like brand new, not a scratch or knick on it

I might be wrong but this sounds like what happens when you have a corrupted emmc. If I am right, this is a hardware issue. One quick way to check is to flash the latest official firmware via ODIN. If I am right, either Odin will fail or you will have the exact same ROM you have now even after Odin install.

Can you write to the internal SD once in the Android? For example when you take a photo or download a file does it get saved on the phone? If the answer is yes then it cannot be a hardware issue. Just a permission cluster-fu..
Get a Linux environment ( boot up your PC with a live CD or something) mount the drive use root su/sudo commands to set chmod 777 on the entire mount

it very well could be hw issue, the internal sd card is not the same partition as the system partition, writing successfully to the int sd has no bearing on the nand failure

Yeah I dealt with a guy that had a Hercules with the same issue. Very frustrating because it was the first time I ran into something like that. We couldn't get it flashed with Odin or anything. We gave up on it and I put a bunch of .40 hollow points in it.

that is a very true they are indeed different partitions. I was thinking about why he couldn't even format his internal SD despite not being able to flash his ROM what not. I will go ahead and read in the thread you provided. Thanks vincom.

Topprospect posted a long complicated thread when he had the super brick. If I remember correctly, it involved some ROM code changes to use external SD card as the primary memory. I don't remember if it worked for him. Maybe worth a shot if all else fails and you really really want to use the phone.

Thanks for the input guys. I'm pretty sure this things fried, luckily its not my primary phone. Anyone know offhand what the manufacturer warranty period is for Samsung? I know HTC is a year, ive sent them phones in the past and they fixed them free of charge as long as it was within a year of the manufacturing date, hopefully Samsung is similar.

[RECOVERY] CWM 6.0.4.5 touch & non-touch

So recently I've been trying to compile a 4.4 compatible TWRP for our device, but somehow, this time around, it turned into a CWM. I had all my TWRP flags in the right position, but I digress.
I am proud to present to you CWM 6.0.4.5 touch and non touch for the Samsung Galaxy S Blaze.
The following link contains both builds. The non touch was compiled from source while the touch recovery was compiled through Koushes Recovery Builder.
THIS IS FOR 4.4 ROMS ONLY. I CLAIM NO RESPONSIBILITY FOR ANY DAMAGES THAT MAY OCCUR IF YOU CHOOSE TO USE IT OTHERWISE.

I'll perform some maintenance on the thread a little later, but until then...
ENJOI
(Hopefully one day I'll have the twrp for you guys.)

Sweet! I've been waiting for a touch version! Checking it out now!

Excellent -- thanks for the efforts Sky!

If you want twrp you need to pull Omni's bootable_recovery, unzip it and replace it with the cm recovery in /bootable/recovery.
From there make the general builds.
I've been trying to get this working for weeks as the mounts don't seem to work right. That's why omni is being delayed.

Works great so far. Only minor issue is that the font is a little too big to display the full description in the "install zip" menu but it's no big deal since I already know the order they appear in (sdcard0 then sdcard1). Thanks Skywalker!

Did you try this flag? It looked promising, but with my ridiculous build times I haven't gotten around to it yet.
ignoreblkid -- blkid is used to determine what file system is in use by TWRP, this flag will cause TWRP to skip/ignore the results of blkid and use the file system specified in the fstab only

Problems with mounting system..

Hi, for some reason the system keeps unmounting itself, I'm running on TWRP 2.7.0.1 recovery with Slimkat 3.8 weekly ROM and next kernel, I tried using fix permissions, but the system still keeps unmounting itself,

brother is your sd card ok
i also experienced the same but after i inserted different card and then again inserted my first card and booted in recovery and wiped cache partition
it worked
if the problem still persists then it might be a hardware problem due to falling or something like that or there is a problem with card slot of the tab

My sdcard is in good condition
what I meant was the system or internal sdcard, it keeps unmounting itself even after fixing permissions...
maybe the internal is broken, I'll try to go to samsung for support, but I forgot that I'm rooted :sly:
