need help with linux swap issues !!!!!

i did the partition, and for some reasons, i exchanged my phone for a new one but after i rooted my phone and flash the cyan rom, and when the phone starts up, the error messages pop up, i think its about the weather widget and calendar widget, saying it's not responding whether to force close or wait. But this is the new phone and fresh new rom i just installed. So I think those programs were still in my sd second partition. My question is, how do i format the 2nd partition or uninstall the apps ? i tried to master reset, but didnt work, and if i plug the usb cord into the computer, i can only see the primary partition but not the secondary one. So now, i cant remove the apps that i installed before, and those error messages pop out everytime when i turn on my phone.
Hope someone here can help me with this

its not ur linux swap part., ur apps are at ext
to clean up ur ext2/3/4
recovery -> alt+x
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# rm -rf /system/sd/*
# reboot recovery
use search next time

oh...but i deleted the partitions and formatted the sd in my computer by right clicking my computer/manage/disk management, then choose the sd card, and i can see it is devided into 3 partitions 1 is 500mb, and one is 373mb and one is 91mb, i deleted one of the partition then 3 partitions merged into one, then i formatted it. But in my phone, it still has the "SD card secondary" section. So should i re partition my sd again like b4 ? and if i dont want to, how do i make the "SD card secondary" go away ?

is this a troll or is he serious?

how do i make the "SD card secondary" go away ?

Help, low on space on newly flashed g1

I have just recently flashed my old G1 to the following
{

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I have only 9 apps installed and I keep getting the 'low on space' message. I can't even update my current apps without getting this message. Any suggestions.
Another question I have is how can I install the Google Talk app? Thanks

well how much space do those apps take? are you putting them on sd? sdext? internal memory? you can use cmtd if you want more room for apps in iternal, you can partition sd card to put apps in ext3 or ext4 if you'd like. you can move them to the fat32 partition but they would be much slower
as for gtalk, just google search "googletalk.apk download" push it with adb or use a file explorer to download it to your phone

thanks for the .apk now i just need to figure out how to partition th sd card
ps. i decided to try out CM5, so far it is a lot faster than the rom i had originally flashed. will keep an eye on memory issues.

you have amonra recovery right? back up exerything from sd card to pc, boot to recovery choose partition sd, choose 512mb and no swap, the rest fat32 (this would be my preference but do as you please) wait until finnished, change ext2 to ext3... wait (you can stop here but I prefer ext4)
now put what you want back on sdcard. I beleieve your rom has the ability to automaticly move apps to ext, check in settings... if not that you may have to enable it via terminal

thank you for the quick tutorial, with cm5 i now have 40.9mb of phone storage(after installing facebook) and 1.77gb on external card. i dont see installing many other apps as this will be a backup phone to my current Galaxy Tab P6800, plus i also have a Galaxy S phone to use as back up as well.

[Q] Really confused about mount points and device names

I'm really really confused about some concepts of the Android OS mounting system.
What is the "/emmc" path? Is it the internal memory mount point or the external?
What does "/sdcard" represent?
Why are they different when the device is in recovery mode than normal?
Please someone shed some light here.
Thanks.

Different Roms use different mount points. For example internal sd is mounted as /sdcard0 in cm10.1 and external sd as /sdcard1.
Samsung prefers /sdcard as internal and /emmc as external. Please someone correct me if I'm wrong.
About the recoveries I don't know. I had a rom which exchanged to internal and external cards in recovery but I don't think that's relevant here

/emmc is embedded multimedia card, so this must be the internal,
/sdcard i believe is also the internal, as it is formatted with a few partitions, space for the /system (ROM) space for the recovery and space for the apps.
i believe they are different in recovery because in recovery it will show its correct name and path (mainly for developers) where as under settings it just shows sdcard because thats what the user will see, and not everyone knows the correct terminology for this so its easier to understand.
then again...what do i know ?? im just making this $hit up lol

Ok.
Let me ask it this way.
How one can know which mount point stands for which hardware entity?

I fail to see why this is different than your previous question ?
Anyways, now you've made me confused too !
For example I'm using Slimbean 4.2.1 beta 1 right now and here's what I found out:
First up, root explorer says the external sdcard is mounted as /extSdCard and the internal (the available internal memory w//o the system partition as azzledazzle pointed out as /sdcard.
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But, Solid explorer says that these two are just links to /sdcard1 for external and /sdcard0 for internal.
As you can see, both are links to /sdcard1 (for external) and /sdcard0 (for internal) respectively. Going to /storage and longpressing on SD card bring it up as mounted under /sdcard1
OI file manager also shows the same results (but unfortunately not the linking part, just that /extSdCard and /storage/sdcard1 are the same place & /sdcard and /storage/sdcard0 are the same.)
The /extSdCard serves no purpose (I think) as MX player ignores it totally.(Don't go for the highlighted fairy tail, there's a folder sdcard1 down the list !)
CWMR uses the /sdcard for external and /emmc for internal.How that comes to be, I've no idea...bcoz according to Root explorer there is no partition such as /emmc although there is /sdcard ,which incidentally, links to internal sdcard as shown above.
I dunno how to take screenshots in CWMR so I can't post the screenshots.(Is that even possible ? I mean, taking screenshots while in CWMR ?)
Can anybody else help us out ?

I really appreciate your input. What I meant by my question was to have concrete way to know what device is mounted where per each ROM.
So according to you there is no organized system in mounting each memory and it's a total mess!

Wait, I just downloaded a Touchwiz ROM.Let me see if there are any differences.....
Okay, now I'm running Slimwizz(or something like that)
Anyways, here is what I got
AnTek Explorer
No /extSdCard present.
/storage/sdcard0------->Internal
/storage/extSdCard---->External
CWMR gives the same results i.e.
/emmc----->Internal
/sdcard---->External
So I gues it can be safely assumed that CWMR is giving consistent results and hence is right ?
Still doesn't explain what use does the /extSdCard link does in AOSP roms.

some kernels have it swapped, be carefull wiping those.

[Q] Files dissapear from internat SD card after reboot

Hi all
I'm trying to replace the stock ROM on a i9000T variant, specifically tried to install CM10.1
It doesn't work, and I have 2 weird symptoms:
1. I can't really clear data\factory reset. For some reason some of the information on the device (several apps) stay installed even after clearing everything several times, and flashing a stock ROM using Heimdall.
2. Whenever a copy a ROM ZIP file on the internal SD card, whether using normal USB copy or ADB push - the file disappears after a reboot.
Do someone know these problems?
Thanks

It seems I am unable to uninstall user apps as well. The seem to uninstall, but come back after restarting the phone...

This would indicate your Internal SD card is failing , you may need to use External SD card, to act as the Internal Sd card for phone to function. Look at My Android Solutions, link below for
[ 13 & 14] Problem:-Getting this when you try to Boot...
E: format_volume: rfs format failed on /dev/block/mmcblk0p1. or
E: format_volume: rfs format failed on /dev/block/mmcblk0p2 or

Is there any way that I can see where is my space wasted? There is just no way my data is 12 GB.. please help!
I tried:
- cache wipe - not working.

delete everything in data/media EXCEPT 0, if you're on 4.2.2 or higher version of android. if you're on lower, ONLY delete 0.

i hope you didnt delete some essential stuff x.x
anyway, the explanation of problem - stock 4.1.2 sd card mount point is data/media, it was changed in android 4.2.2 to data/media/0, leading to people transferring from stock rom to custom 4.2.2 rom to having double data for every app that needs it (basically every app that i know of).
anyway, if you're still bootlooping, do the wipe data/factory reset in cwm. you'll boot for sure, now just restore stuff with titanium backup or whatever backup system you have in place.
edit2:
for some people, custom roms have problem with RIL. try rebooting a few times, you should get network connection. if the problem is too annoying for you, check out a tutorial i wrote to replace CM RIL with EPRJ RIL in any custom rom, that should fix any connection problems that are caused by RIL issues.

I reflashed rom and wiped cache couple of times, so everything works now. Thank you much for help and great explanation!
