[Galaxy Tab 2 Q&A, Help & Troubleshooting] Ohmster:
Hey Guys,

Wow, the filesystem of AKOP is a LOT different than stock, rooted touchwiz Samsung ICS filesystem!

My current ROM came from these instructions and these two packages:

Install CM10.1 based Android 4.2.1 update on Samsung Galaxy Tab 2 10.1 GT-P5113

cm-10-20121130-EXPERIMENTAL-p5110-CODEWORKX.zip

gapps-jb-20121130-signed.zip

Look folks, I know this is a lot to read. I am sorry but I have 5 questions that I really need answered. Please speed read or just tell me what you know. Please!

Why is my 16Gb of internal storage down to 507Mb free?

What can be removed from internal storage to make more room?

"Settings, Applications, Developer, and check USB Debugger box" is NOT in Jellybean, how to enable it?

I am using cm-10-20121130-EXPERIMENTAL-p5110-CODEWORKX.zip. Is there a newer, better JB ROM for me that is stable and will not "break anything"?

Does this mod contain a screenshot app or must I install one?

Remember I was telling you that I could not get Milestone JB to install on my tablet. Well, I found some different instructions here: Install CM10.1 based Android 4.2.1 update

And this worked perfectly!

One issue that I am having is with Titanium Backup. I keep getting this message:

"System settings may cause problems. Go to Settings, Applications, Developer, and check USB Debugger"

There IS NO SUCH option in Jellybean.

The Settings/Apps options only lists the applications; downloaded, running, and all. It shows all of this being in Internal Storage, 11Gb used, 516MB free. I cannot restore all of my apps, I have no more room to install anything. This is the same device with same internal 16Gb sdcard and 32Gb ExtSdCard. There are NO developer options in the Cyanogen ROM that I installed. Is this a real problem or is there a hidden option or workaround for it?

Picture of the About Device Screen:

Now this worked like a charm. No problems at all and I really like Jellybean. I also installed the corresponding gapps zip and all is well. Deleted the cache and the dalvik cache and went clean. Of course I did a CWM backup first and did all of this in CWM ROM Manager. I am really happy with all this and I think there are updates that are better as this is from November and is labeled as EXPERIMENTAL.

There is now another one, the gapps is a file called: gapps-jb-20121212-signed.zip I did update with CWM but did not get the gapps so I had to restore. This Cyanogen ROM is nice but the filesystem is different. sdcard is in root AND under /mnt. /mnt now contains 7 folders. extSdCard is also under root and under /mnt.

asec

extSdCard

obb

sdcard

secure

shell

usbdisk0

Both sdcard (internal) lead to the same location. Both sdcard folders appear to be the same, not sure how to tell with ES File Explorer Properties. Both of them are called "Folders" and appear identical. No mention of symlink or anything else. Do I have duplicate of the same storage device?

One serious problem I have is that all my internal storage is all but gone. I can only restore about 30% of my apps without data before I run out of room. I DO have a 16GB external SDcard where I keep my pictures, personal files, and many installed apps have the option to move to SDcard by ZDbox or Android Assistant. Now I have a serious storage problem. I cannot install all my apps "because there is no room on card".

Internal Storage shows a big bar graph, about 30% is used up by the color bands listed below, over 60% is dark gray and what I assume to be available. All categories are colored bands on the bar graph.

Settings/Storage does list my two cards, what size, and what is free and used.

Internal Storage Total Space = 11.87Gb. Available = 525Mb

Available = 525Mb

Apps = 625M (app data & media content)

Pictures, Videos = 692Mb

Audio (music, ringtones, podcasts, etc.) = 853Mb

Downloads = 226Mb

Cached data 18.76Mb

SD Card Total Space = 14.53Gb

Available = 3.02Gb

Here is a picture of my Storage Settings View:

This AKOP stuff is GREAT, but where did all my internal storage go? I have sdcard duplicated, The bar graphs tell me nothing about where are all the additional gigs of space, and I cannot restore most of my apps because there is no more room.

I really love this and want to keep it but I need some room back on my card! When I wanted to restore from CWM, Touch or even regular, no backups could be found because they were on the internal card where CWM put them, yet all I could access was the extSdCard. I could choose to mount the internal sdcard, from CWM boot menu, but it would NOT mount, thus the backups were not available. Is this an issue that I can fix or should I copy ALL backups to the extSdCard?

Just checked Properties in ES File Explorer on the /sdcard (Internal) Shows as "Folder". Size 3.86Gb. How can I check this internal card and get my space back? Let me check in ESFE my extSdCard "Folder" size while I am at it. 11.6Gb.

Please, give me some insight!

Can you guy give me some ideas or help please? Thanks!
