[Q] Help With VM heapsize - Android Q&A, Help & Troubleshooting

Right now i have a boot loop. What i did was that I changed the heapsize to 12 in the /system/build.prop (wanted to be fast) and now it just wont boot. I guess its too low so i did a logcat on adb and it says:
Code:
W/dalvikvm( 1323): JNI_CreateJavaVM failed
E/AndroidRuntime( 1323): JNI_CreateJavaVM failed
Luckily, root explorer saves everything with a file ending .bak. What I did was I used adb to pull the file, renamed it to simply build.prop but when I try to push it back into /system/ it says that the partition is only in read-only. So i try to adb shell and remount the system partition but then I get:
Code:
C:\Users\Alex>adb shell
$ su
su
[1] + Stopped (signal) su
$ su
su
[2] + Stopped (signal) su
[1] Segmentation fault su
What do i do?!?!!?? help, i've tried my best..... oh, and my phone is the motorla spice xt300 running 2.1 stock

Restore to previous working condition backup will do.

only problem is that development isnt that good for my phone. plus it has a locked bootloader which makes it worse so I dont have a nandroid backup.

You should be able to change it with Root Explorer. Did you make sure to check the R/W option on Root Explorer? It will then allow you to change read-only files.

[Q] Rooted or not?

Hi, I rooted my Vribrant, both ways (manually and with one click root). I installed terminal emulator. I tried the su command to check if I am root. The # appears normally. However I tried deleting a file with Root explorer, inside the system folder, and when I get back it's still there. I also tried deleting it manually from Terminal EMulator with these commands:
su
cd system/apps
rm Swype.apk
and I get this:
rm failed for Swype.apk, Read-only file system
I also tried:
su rm Swype.apk
and this is returned:
Permission denied.....
I also tried the exact same thing from adb shell (which I had to allow in superuser permissions program), but it gave me the exact same results. What's wrong? Am I doing something wrong? Thanks
In root explorer, try hitting the r/w button at the top and see if that works.
Sent from my SGH-T959 using XDA App
I know about the button. The strange thing is that inside system folder it grands me r/w permissions, and no matter how many times a press the r/o button it doesn't change. Still gives the results I said. However, besides root Explorer what's wrong with terminal emulator and adb?
I'm not 100% sure how to mount as root in adb. I wish I knew myself heh.
Did any of those root methods install the superuser app?

I tried the first method but it didn't work. When I entered adb root, it said "adbd cannot run as root in production builds". I searched a bit and found that I must have a rooted kernel for this to work. (I guess it's different from the root method I tried in "how to root vibrant").
Anyway the second way worked, where i replaced mntblock3 with stl9 for my phone. I tried the rm command and it worked! However as soon as I exited terminal, I couldn't delete other files. I had to retype the command. I can't do this everytime I need access in System folder. Why is this happenning? Does this have something to do with the fact that root explorer cannot change r/w to r/o mode while in system folder?
what if you open Superuser
Click on Root Explorer.
Click on Forget.
Open Root Explorer and grant Root Access and check to remember it.
work now?
Moved to Q&A, please post in the correct section.

No it didn't work. I also installed the latest version of SuperUser 2.3.6.1. But without a difference unfortunately.
What works for me, is installing sgs tools, and whenever I want to do write operations on system folder, run the appropriate script from sgs and then use root explorer......
Although I think there's something wrong? Why doesn't the mount r/w button work in root explorer, and why do I have to remount the file system through SGS tools, every time for it to work?
makes no sense to me either. Have you uninstalled RE and the installed it back granting root once reinstalled?
Yes several times.....
I am giving up. I just have to go through the whole process every time. I found some other people having this issue. I am on stock JI6 firmware. Maybe when I read a little bit more I will flash a custom rom.
Download and install Super Manager. Pretty handy program to use for Root users.
I'm not sure what the issue is,but mine does it too. I'm running the "unofficial" froyo JK2 build,flashed via ODIN,and I'm having the same issues. root works,root file explorer is stuck in rw,won't let me switch to ro,and it can't do anything to files in / or /system. manually remounting it from terminal or sgs tools works.

At least I am not the only one with this problem.... haha
I forgot to mention that I use Root Explorer version 2.12.2
When I try a custom Rom I will post the results....
^ why not get the update, .4 is the most recent build. Do you have an illegal copy?
It's not only root explorer. It happens with other file explorers too like android mate and super manager... Inside system folder whatever, I do doesn't happen unless I unmount and remount like before

HOW to reach 2.1 system files from 2.2 ROM

Hello all
I need help
Unfortunately I have managed to damage my 2.1 rom. (i have replaced 2.1 framework-res.apk)
Now I cannot boot into it , problem is that I do not have a backup, so I cannot just easily "reburn" the firmware.
I have 2.2 ROM implemented. but I do not -know how to reach 2.1 system files from it. There is some chroot done in boot process imho .
Can anybody help me how to reach the files

If you're lucky it will mount your 2.1 system partition as /21system
Most likely it will say "Device or resource busy"... But worth trying anyway.
Cheers

I had to think about remount
Going to try now ..
EDIT:
You are absolutelly right : Device or resource busy .
What should I try now ?
I found out that I can reach 2.1 system in adb , but my root do not work. so I cannot do anything to the system partition . Any ideas how to achieve root in this state ? On phone display there is still only firts sony ericsson logo ..

I did the same thing at least twice. I was able to save it without restoring by replacing my framework-res.apk before it rebooted or froze.
Basically, try to adb into it while it is still at the Sony logo or if you get the blackscreen after the logo.
One weird thing I did notice was that I was able to replace the framework-res.apk file apparently without using 'su'. After I killed it when I was doing adb at/after the logo I tried to 'su' but it gave some error and remained at the '$' prompt. I then did the 'dd if=/sdcard/framework-res.apk of=/system/framework/framework-res.apk' command and it completed. Rebooted and it worked again.
Think my whole thing was tested second time with a script.
Try making a frameworkfix.cmd file and putting this in it.
@echo off
@echo.
@echo Installing Framework
@echo.
@adb shell su
@adb push framework-res.apk /sdcard/framework-res.apk
@adb shell dd if=/sdcard/framework-res.apk of=/system/framework/framework-res.apk
The keep trying to run it while at the Sony logo. Give it a few runs before you give up, I swear it worked for me.

Heck just try the following from folder with your original framework.
adb push framework-res.apk /sdcard/framework-res.apk
adb shell dd if=/sdcard/framework-res.apk of=/system/framework/framework-res.apk
or
adb push framework-res.apk /sdcard/framework-res.apk
adb shell
su
dd if=/sdcard/framework-res.apk of=/system/framework/framework-res.apk
thanks guys , but I do not need commands,
I know them already , I had permissions problem.
Instructions mentioned above did not worked for me
I've got permission denied
anyway thanks

You can access the 2.1 /system partition through 2.2 with adb.
Use this to unmount 2.2 /system
Code:
su
busybox umount /dev/block/loop1
You can check if all worked well this way:
Code:
busybox ls -1d /system/* | grep xbin
If it gives you anything, it's 2.1 -- if not, try
Code:
busybox umount -l /dev/block/loop1
Now, you should have the old 2.1 /system structure available. Ignore all errors appearing *on the phone* it'll be screwed up, unusable. Until a restart.
Now through adb you can overwrite your 2.1 framework apk with dd
(assuming you already have it on the sdcard, else, well, push it there (adb push framework.apk /mnt/sdcard/ )
Code:
dd if=/mnt/sdcard/framework.apk of=/system/framework/framework.apk
for remount system, just do
Code:
busybox mount -o remount,rw /system
after you have the 2.1 system available.
I installed 2.2 to my nand (almost fully working) at one point this way =3
Or...
You can flash again just using system.bin and everything you had would be there.
;-)
You also will need loader.sin
I did this a couple of times and work for me; I only need to root again
Good luck!
PS: In the firmware folder, you need to leave ONLY this 2 files: System.sin and loader.sin. Backup and delete all other files like amss.sin, cache.sin, etc.
well thank you
This a good idea ..
Unfortunatelly I already reflashed the phone
Hope it will help to somebody in the future

Thought that would work, was going to do it with .003, but I guess the recovery tool will do that for us - now we see what Z has been working on - excellent news
Just curios. Any speed improvements when extracting the img files to nand and mount/run it from there ?
Even running from sdcard img files is a perfect backup solution by just copy the img files away from time to time. But of course r/w cycles of the card are increased --> less lifetime.
But otherwise running from images is nice, as you're able to mount them. (diskinternals linux reader but R-only)
Anyone knows a win32 prog to mount the img files r/w ?

[Q] How to ADB push?

I'm trying to push files to /system via ADB. However I'm having problems (getting permission errors). I am running Eclipse 2.0.2, so yes, my phone is rooted, I have su and busybox.
Phone is connected to PC and is set as "USB Mass Storage".
USB Debugging is ON
Here is my CMD log:
Code:
C:\android-sdk\tools>adb remount
remount failed: Operation not permitted
I tried to remount and it failed
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to
'/system/myfile.apk': Read-only file system
I tried to push, and got a READ-ONLY FILE SYSTEM error (keep this in mind)
Code:
C:\android-sdk\tools>adb shell
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
I try to push inside of ADB shell. Nothing again...
Code:
$ su
su
# mount -o remount,rw /dev/block/mtdblock4 /system
mount -o remount,rw /dev/block/mtdblock4 /system
# exit
exit
I go into SU and attempt to remount the /system
Code:
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
$ exit
exit
I go back up to ADB shell and try to push again... same error as before
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to '/system/myfile.apk': Permission denied
I go back to the main command line and try to push again. This time I get PERMISSION DENIED. This error is different than before.
Any help on the matter?
I've read about ro.secure needing to be set to 1, but I need to edit the boot.img in order to do this, correct? Does that require an unlocked bootloader? Is root ADB even possible on the DX2.
Thanks!
I am no expert (don't even know if i know enough to b called a newb) but maybe try a root explorer. I use es file explorer because it's free. In settings check root explorer and mount file system. I received similar errors and this solved my problem.

I'm familiar with root explorer, it's easy. I'm wanting to be able to use ADB though. Your post made me try something new though. I plugged my phone into my PC, then went into root explorer and mounted everything as RW. But, still was unable to push via ADB. Thanks for the reply though
So, how can I get ADB working?

Make sure there are no spaces in the file path to your android-sdk folder. Can't say if this is your issue but its worth a shot as it has always caused weird problems with android development since day one.

Ro.secure is in your local.prop on the root of your phone. As far as your issue you have to reset permissions in order to push to /system. I saw that you were trying to do that but with no success. I believe I know what will help but I will have to find it and repost.
http://forum.xda-developers.com/showthread.php?t=1133528
Ok look at the command lines at the bottom of the op. You are going to use adb shell. Follow that almost exactly but adjust according to your directories. Should go into adb shell, gain su permissions, mount /system rw, push your apk, then don't worry about remounting as ro, just reboot. Pay close attention to spaces.

Took me a few days to be able to getting around to trying this, but it didn't work :/ I'm still getting all of the same errors. The /system just doesn't seem to want to mount as RW (even though it is possible when using root explorer).
As for ro.secure in my local.prop, I'm able to edit this but it resets on reboot because (from what I've read) this is a file generated by the kernel
Anyone else have ideas?

Thanks for that! It's not quite what I'm aiming to eventually do, but did give me more insight on how the whole adb/shell/su systems work. From inside of su, I was able to mount the /system as RW, however I'm only able to do this from inside of SU. I want to be able to do this from the initial CMD so that I can ADB PUSH from my computer to the phone.
Here's my latest log:

So now the question is, how do I mount as R/W so I can use ADB push?
Wes
Maybe its because im tired but im confused as to why it wont let you push your files if you have remounted as rw. At that point it should be cake. You gained access to system by remounting it as rw successfully already.

Try:
Code:
adb devices
adb remount
adb push [filename] [destination]
adb reboot
the "adb remount" remounts the fs RW instead of the default RO.
I'm no expert in ADB, but I had run into the same issue as you and for me the fix was to go into ADB SHELL , then type SU to get SU access, then type exit twice to get out of shell completely. Then I tried pushing the APK and it worked fine with no read only errors.
This worked for me on my SGS2, could work for you ! Goodluck !

did you ever get this figured out? I'm having the same frustrations on mine. Mine won't install the 2.3.5 update due to it not recognizing the Quickoffice.apk and I'm trying to push the files manually, but I'm having no luck getting past the same you've posted here.

Do this
Sbf to 2.3.4
(or 2.3.3& take one ota To get to 2.3.4...however you want to do it..just be bone stock 2.3.4 )
Root your device.
BUT DO NOT USE ZERGRUSH TO ROOT
Use petes Motorola one click root method.
Then continue the process as normal from there on out.
Trust me in this. Zergrush root method is not playing nice with your /system partition, (if you notice during the root process it might say something like "making room in system,"= or "moving/deleting app to make room" something similar)
And when it does that, it's messing up how the update checks for untouched stock apps.
Let me know how it goes.
This solution has worked for COUNTLESS others so far, zergrush has always been the culprit when it comes to failing to find certain apk or system file that needs to be there for the update to install.

This won't work with Eclipse since it's not using 2nd init. I asked this question in the Eclipse forums and Nitro responded with the following:
Not without using 2nd init. All of that works due to being able to load its own init.rc which starts services and passes parameters, etc.. during boot time. It is possible to make a stock rom use 2nd init. CM9 will not even have root enabled by default. The only other way to push stuff is to enable root shell prior to pushing.

I know that CM7 allows using the adb remount, but that's because it's using 2nd init. I had also asked the question about why CM7 defaults to root shell when you adb shell into it and that's why he mentions how CM9 won't have root enabled by default.
The way I push to Eclipse is to run root explorer on my phone and mount the directory r/w. Then, I can use "adb push" to the phone.

I think I may have tried that in one of my iterations. Originally I had it rooted with One-Click and then I was having issues with the 2.3.5 OTA update (quickoffice.apk) and at this point I've SBF'ed and rooted it probably 5 times this week so far. Rooted with both One-click and zergRush at various times. Actually I think every time except this last time has been with one-click. So I don't think that has seemed to make a difference for me so far. I can try it again, but if there's any other advice to throw out in the mean time, I'll take it.
Alternatively, I may take the new phone (the first replacement they sent had 2.3.5 on it, but a bad menu key causing the phone to flip out), load Titanium Backup on it, backup all the system apps and restore them to my original phone. Worst case is I have to SBF it again. But that seems like a logical process since I will have two phones available.

Hi,
i accidently changed the permission of the folder "system" to READ only. atleast i think so... i used Yaffs Explorer to change permission of "system" and i ticked the first line on all 3.
again.. this was an accident cuz i didnt know what i was doing.
now the problem is my phone just keeps restarting ... and then it boots into recovery (3e) on its own...
i tried using ADB to change the permission with adb shell ... and all that.. problem is
adb works. phone connects and shows off as device.
but if i try using the adb shell command or any other command with adb ( except sideload ) it tells me
"PERMISSION DENIED" and similar messages...
i have no clue how to safe my phone now any help would be much much appreciated.
i thought something of my own...
is it possible to write a shell script which changes the permission of "system" folder to its correct one.. make it as a .ZIP file and update use it with "update from adb"
please any help^^
best regards
Krype
I assume you are rooted have you gone into CWM and reset permissions?

[Q] [help]how to get system folder permission for hdx7

I just play andorid device a few days, but My hdx7 is a little bricked because i deleted some system app. Now I can log in fire os, have adb, usb connected and internal storge, even i can operate device setting app, but i can't open the other app because i don't have a desktop.
I compare system/app folder with the same folder in the amazon bin, found that the folder lack of scores of app, but the other system folder is the same. So I hope can adb push app folder to the system folder, but the pemission denied. I try to remount or mount, it can't work.
if adb root, then "adbd cannot run as root in production builds.
if adb push apk to the app folder, then “permission denied".
if adb remount, then ”remount failed: Operation not permitted".
and I have try adb shell like that:
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system
# exit
it didn't work.
my hdx7 have rooted.
My Questions are:
1. If I could push the app folder to the system folder and reset to factory, is my hdx saved?
2. How to get the system folder rw in the situation?
thx for any prompt, although i am a rookie but i will try my best, i wish the adept can help me and will be enormously grateful. Sorry for my poor english.
It sounds to me that you had lost root.

Hmmm... It says you still have root (the prompt changed after "su")
I personally don't use ADB much. I have Root Explorer (grabbed it legally for free from Amazon ages ago) and Wifi Explorer Pro (same method) so I basically WiFi myself the files I need sideloaded then move them around on the device itself. But if you've lost launcher, you have deeper issues.
Have you tried ADB push any launcher? Or even a download store like 1Mobile or Aptoide?
ADB is basically a Linux shell debug into Android, so you need to learn some Unix shell commands. I'm sure you can find ADB guides with the basic commands, like "ls", "cp", and so on.
You need to check the directory and see if the system/app and other system directories are still there. This is one reason I only play with the copy of ROM I have (see Safestrap Recovery).
