General :: Unable To Make Permanent Writes / Changes To SDCard
Jun 30, 2012
I have been unable to do anything permanent to my sd-card. I was on my vacation so all my vacation photos were deleted. It is writable, I can delete, write and change as I want but when it's rescanned all changes (delete, write etc...) were never made and it sets itself back to the 23rd. Now I have access to my computer so I formatted the sdcard hoping it would fix it. After I put it in my phone all files popped back up. So my case is:I cannot make any permanent writes/changes to it.
Formatting doesn't seem to work. Once again, it is writable (Temporarily), i took a photo and pushed it into the /system partition, it was there but not on the sdcard after reboot. Root explorer have options for mounting it R/w and R/O (It doesn't normally do that).

I was able to root Karbonn A37 (MTK6577) using the software from t URL.....After the root process it instalsl this app - URL.....This app is in Chinese and it manages all the root permission requests as well as installs its own su and some other files.
I have tried to root using many other methods available here and only the above method was successful. After rooting I tried installing SuperUser and found that su is always getting overwritten. I would really love to use the standard English version of su and superuser, but if I uninstall the the Chinese app, the root access goes away.
Any way to make root permanent without the Chinese app and mange root permissions using superuser. Also what is this Chinese app doing, that none of our other rooting methods are not able to do?

I am about to build an app which needs to use device internal storage memory extensively, a lot of reads, writes and overwrites of the files.
I assume that most of the android devices use a kind of a flash memory, but where can I find more data on this topic for the most common memories used, like how many reads/writes can an internal flash endure before failing?

Is there a way to hide permanent notification icons in the staus bar, like the Juice Defender Icon, Lux, App Clip, and etc? These take up room for the regular notification.

I am trying to sync a rostering app between two devices using dropsync. The .db files that need syncing are in the /data/ data/com/databases directory. Using Root explorer I can change the permissions to give full rw permission to others. The two .db files will then upload to the dropsync server.The problem is that whenever the app is opened and anything modified, the permissions change back to default and thus dropsync can't access the modified .db... Is there anyway to change this or am I wasting my time? what is the 'sticky' box option in RE?

I want to sync my Facebook images INTO Google contacts. Is there something that will do this?
"Contact-Sync" or "haxsync" do not do the job as it relies on simply joining contacts and display correctly for only one phone/rom. Problem is that the image is only linked on your phone but not really linked directly to google contacts.
Setting an image to a contact from a file appears to do the trick but there is no way that I know of to automatically set a facebook picture into google contacts.

I can't seem to copy files to the sdcard inserted into the phone. When I try to do this with Windows Explorer, it just hangs there, and the sdcard area of the phone gets really hot. Once I unplug the USB cable Windows Explorer resumes, but the phone is still stuck there and unresponsive to any button/touch screen presses, and the phone remains hot. Copying from the sdcard works.

On both the emulator and my actual phone (tattoo) I seem unable to browse the SD card - when I run ddms and use the File Explorer, I can browse /data or /system fine, but /sdcard refuses to open, and its permissions appear to be "d---------" (which of course might be the problem).
Similarly when I use ddms's "Put file on device" it fails:
29:43 E/ddms: transfer error: Permission denied Failed to push about.html on SH9CELG00306: Permission denied
The above is for my actual phone but I get a similar error on the emulator (which does have an /sdcard).

I am working on a project for a school system where they want to used deactivated donated phones in the classroom for WiFi access only.They will be reset to Factory Defaults, so we'll need to get pass the Activation screen.
It will be a variety of phones so that is why I am posting this here.It appears there are several different ways of bypassing the screen.I seriously doubt that they will allow Rooting of the phone, but I will pass it along as a suggestion.
Seems like the most common is the 4 corner clockwise tap. This seems to work for HTC and Motorola.What I cannot find is if this is permanent or not? If the phone Is powered off and then back on, does this have to be done again or is it once and done?I've read both, but without device in hand, I cannot confirm or deny.
Is there a list out there for all the models that support this?Samsung looks like you have to dial *#83786633 But this does not seem like a permanent solution--has to be done every time.Permanent seems to Root and delete or freeze phone.apk or setupwizard.apk?

My EVO actually writes to sd card faster than it reads it. I test 3 different memory cards. The speed varies a little but the end result is the same. The write speed is much faster than the read speed. I only notice it now because I usually transfer files to the card and delete them later on. I finally made a few backup roms (4 at about 2GB total size) and tried to move to my laptop. Needless to say the process was slow (over 30 minutes). I can transfer the same files back into the card in the EVO in about 4 minutes.
Below is a same of my transfer speed in the EVO. The same card outside of the EVO has a write rate of 7-10 MBs and read rate of 17 MBs. http://i175.photobucket.com/albums/w159/fithos_bucket/snap20100818_095238.png

I purchased a AOSON M60 fabbed at foxconn a couple of weeks back, it claims to be pre-Rooted. From Item Description: "The machine has obtained permanent ROOT privileges, a great convenience to the user management system software and remove unwanted software."
I have tested this with the Root checker app and it fails reporting that the device isn't rooted. I have checked this with Titanium Backup and it also reports it's not rooted.
When i have checked this with SuperOneClick v 3.2.2 it says:
Checking if rooted... CheckIfRooted 0.14s True
Checking for shell root... CheckIfShellRooted 0.15s False
The application then stopps at Shell rooting device...-Step #7 WaitForDevice (This never completes)
From my simple understanding, the shell rooting is a one shot thing per boot, and isn't required if the device reports back that rooted=true.

I need to write a fairly simple .csv file to the device's sdcard (so it can then be emailed via Intent). The below code does not write the file.
CODE:...........
More code here:
I flush and close out_stream. I can even seem to be able to read from the file on the device (printing above output, using fileinputstream, to an edittext.
How can I get to this file on the sdcard?

Today I was in the middle of sms conversation and suddenly I realized that my phone lost it's ability to send messages as well as calling/receving calls.
Here is info about my phone:
Model/firmware:
Currently flashed rom: I9070XXLQB_I9070OXXLQB_HOME.tar.md5
Model number: GT-I9070
Android version: 4.1.2
Baseband version: I9070XXLQB
Kernel version: 3.0.31-66490; se.infra@sep-116 #2; SMP PREEMPT Tue Feb 15:52:28; KST 2013
Build number: JZQ54K.I9070XXLQB
Network information:
Network: T-Mobile.pl
Signal strenght: -79 dBm 17 asu
Mobile network type: EDGE
Servise state: In service
Mobile network state: Connected
My phone number: unknown
Offline mode is obviously off.
APN matches network.
*#06# shows correct IMEI.
I searched and did everything (flashing another rom, factory resets, swapping SIM card, removing battery for 15 mins, etc.). Only thing that I haven't done is flashing modem, because I don't know if I can flash it on i9070.

I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.
I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?

I'm looking for suggestions on how to go about adding a ListView selector that is 'permanent'. By this, I mean a single row in the ListView is always highlighted; it should move up or down in reponse to any D-pad presses (i.e. like the default selector) but also remain set/highlighted if the user were to scroll the ListView in either direction (i.e. it's still highlighted even when it's off-screen).
I've looked at using the standard selector mechanism, but am unable to get the selector to remain in place if the ListView is touched (and thus scrolled), so it makes me think that this isn't the best option? Perhaps there's a <selector> "state_*" that I've ignored?
The other option would be to use the onItemSelected() callback, but at first look this appears more convoluted?
Any suggestions/recommendations/experiences gratefully received.

I've been having internet troubles since i got my Hero a few weeks ago.
It seems to jump between '3G' and 'H' when I use any applications using the internet. This means that pages often fail to load/download, or appear slower than 2G connection speeds.
I think this is because I'm in an area which can just about receive HDSPA speeds sometimes, but not consistently, so I was wondering if there's any way to set the internet to stay at 3G and not attempt to connect to HDSPA? When I'm in areas where the best speed possible in 3G, the internet is infinitely faster than when it's jumping from 3G to H and back.

So I've spent a fair amount of time reading all that I can about rooting before I actually decided to do it, but hit an unforeseen wall. I read about both the manual way and the instructional videos on youtube and decided to go with the videos. I rooted fine, and was in the process of doing a android backup with DroidRootHelper. So I downloaded and extracted the Tools folder and I thought everything was pretty straightforward until I realized that the instructions in this video

I am developing an app which has one service running in the background even if the application is closed. This service basically listens to the server via socket connection. It is an app's requirement to keep one consistent connection open. but this drains battery liek anything. I know socket is costly affair in the sense of battery life. Do anybody know any other way to keep communication channel open? or any optimization in using socket?

I have had my Eris since Jan. I am on my 3rd replacement and 2nd in 3 weeks. My first one VZW just kept making excuses and wanting to do factory resets and delete apps because in their words that was the problem. The tech guy on the phone told me that they could only replace it with another eris again so here I sit with another POS that continues to lock up. I have been unable to make calls 80% of the time. What a joke On average I have to remove my battery 3-4 times a day to get it to work.
