[Q]Galaxy Tab 10.1 problem

I purchased my tab in China. Samsung China has deleted all Google apps from the pre-installed rom. As a result, the Chinese GT 10.1 community has compiled an Google app pack (GoogleServeice_P7510.zip) to bring back those apps.
I flashed it immediately after I rooted the tab. The Google apps were installed successfully. I entered my google account after the boot and every google app was running without a glitch. But not long after that I found I could no longer enter browser settings anymore. It would always give me a FC when I tried to do so. I then downloaded the dolphin browser. So this problem was bypassed.
Then I found there was something wrong with the superuser, I could not adb remount/push, and it couldn't be revoked by the apps that required root access.
This problem was partially resolved later by flashing the OC kernel for GT 10.1, which secured adb privileges. But the superuser was still problematic. Then I found out that after I flashed any zip other than root.zip in recovery, be it the kernel.zip, the su_busybox_tools.zip or google_servicepack.zip, the superuser icon in the app drawer would always become 4 times smaller (2 time in both height and length) than the superuser app "installed" by root.zip, as well all other apps.
There seemed to be something wrong with this version of superuser app (small icon). Whenever I opened an app that required root access, the superuser prompt window would not pop out. But if I flashed the root.zip again, the big-icon superuser app would be back. And other apps can revoke it most of time. However, it was not perfectly stable. Somethimes, it still failed to be revoked. I have flashed the root.zip among the other 3 zips for many times to get this conclusion.
I then applied the V6 SuperCharger script and flashed the su_busybox tools for GT 10.1 right before that, because SuperCharger script required busybox. However, due to the superuser problem, the SuperCharger script was not fully working. After reboot, part of the settings was changed back to default, because 99supercharger.sh couldn't be run on boot with root and there's not init.d folder in GT Tab 10.1. Then I flashed the OC kernel hoping it will fix all the problems. After that, I surprisingly found out that I was able adb remount and push. But the icon of the superuser app was again back to the small one. So the apps requiring root could not revoke it for permission.
As a result, I flashed the root.zip again. At this moment, superuser works normally, even after some reboots. SetCPU and script manager are able to automatically acquired root access on boot. But when I rechecked the supercharger script, current pages(minfree) were still showing blank.
Other problems include backspace and enter keys not working in terminal emulator/console. And the problem I just found - the notification ringtone list in the system settings and other app (e.g. Gmail) settings was blank. I could not change ringtone, although the system can play it without problem. And the ogg files are still there in /system/media/notifications.
Since all Android devices works more or less the same. I hope some of you phone experts can shed some light on these problem. The user base of Android tabs has made it less supported than Android phones. It'll be highly appreciated if all these annoying problems get fixed.
Thank you!

[Q] ROM Toolbox Pro: Problems with App Manager

THE BACKGROUND:
I am running stock rooted US .29 on my UnLocked TF300T. The first time I rooted I did the downgrade, rooted and used Voo Doo RootKeeper and then updated OTA to the current FM.
Things were running kind of slow, and I knew that I wanted to start using ROMs once they became a little more stable. So I decided to unlock my device, install CWM and use the "root-signed.zip" to flash root with CWM.
Everything was working fine. I then tried a custom ROM, and it was a little too rough for me. I am not experienced to be testing bet ROMs yet. So I flashed back to the stock FM (.29) and then rooted again using "root-signed.zip".
THE PROBLEM:
The problem is that the Liberty ROM Toolbox Pro isn't fully functioning. I have tried re-installing it, re-installing my FM and rooting it different ways, etc., etc...
No matter what I do, everything seems to work in the ROM Toolbox except for that I cannot:
- Uninstall ANY Apps (system, root, or DL'd Apps).
- Can't make any changes in the "Auto Start Manager".
When I try to uninstall an App:
- The "Super User" notification pops up like normal saying that ROM Toolbox had been granted permission.
- The ROM Toolbox notification pops up like normal showing that it is being un-installed.
- Then it all stops like it normally does except for that the App still remains there.
- Also, a RED bar slides up from the bottom (of the window in ROM Toolbox) saying that the un-installation "failed".
When I try to change things in Auto Start:
- The exact same thing that happen in App Manager. Nothing changes and the red "failed" notification bar pops up.
THE QUESTION:
Why is this happening in ROM Toolbox when all of my other Root Apps are working fine?
What can I do to fix it?
Thank You

I'm not sure what is going on to be honest. I have tested this on all my devices and they are all working.
I'm guessing maybe the pm command is somehow not working properly on your phone. In the App Manager try clicking on details and find the package name you want to uninstall. Then go to the terminal emulator and run the following command:
pm uninstall <package name>
If you get a "success" then it uninstalled correctly. If not, please let me know the output. I do not check forums on a regular basis so please email this to me.
Thanks.

[Q] wont boot after changing dpi from build.prop

I've rooted the phone and flashed Cataclysm. However I wanted to change dpi to smaller. 480(Original) -> to 445 or 400 (tried both). Both times, phone shows "google" text, but then its just black screen and wont boot. I had to flash rom again.
I gave permission (777) with root explorer and modified with (rd?)text editor.

I don't think those DPIs work. I"m on 410 and it is working fine. Reflash Cataclysm and try again.

I am using 400 DPI right now.

tried to change to 400 using ES explorer and got a softbrick (black screen after google logo).
I used instructions in this thread to get it to work again : http://forum.xda-developers.com/showthread.php?t=1927198
Or if you use TWRP just boot into recovery and use the terminal command chmod 644 build.prop (it's the same thing as above but done from your device not PC)

Use xposed framework and app settings to set per app DPI also works for system launcher etc. Has a flashable zip that will cancel all changes if you bootloop.

[Q] rom toolbox problem

Okay.. so here is the thing
Tried font installer, tried to change the fonts a million times, but never succeeded. Uninstalled it, tried to install rom toolbox and i did.
Here i tried the font installer again, but failed. skipped this part and tried to install boot animations , downloaded one and when tried to install the same, it says "install failed"
So now i wish to know if there is some app or some possible reason why these super root apps are not working for me :crying:
Please help

maybe your su binary is missing or corrupted. update superuser app and binaries.

[sm-g531h] dpi reduced and now phone just shows wallpaper and notification bar

I installed a pre-rooted ROM on my phone to enable root permissions and I downloaded a DPI changer to set DPI to a lower value and now, the phone just shows the notification bar and wallpaper. I have the backup build.prop file on my laptop but I keep on moving from problem to problem trying to push it into /system. I cannot remount the system to r/w. The commands 'ADB root' & 'ADB remount' don't work. As I try using other codes, I get errors like "Operation not permitted," "Permission Denied," "Read-Only File System," etc. I have CWM recovery and can mount but when trying to use the 'su' command in ADB Shell, It gives an error but when i boot the phone up normally, it works though I keep going in a loop trying to fix. I have tried flashing ROM again but still the same result. I was wondering if anyone could help or give me a flashable zip(if you have the same model).
NOTE: I'm not really sure that the app(s) I used affected the build.prop because it could be the app itself that I need to delete but I don't know how to uninstall. I installed two DPI changing apps where in one, "Le DPI CHANGER" I tried the regular method and it did not work saying that I could try editing build.prop manually but I persisted in getting another application "EASY DPI CHANGER" which claimed that if it didn't work, on reboot it would reset DPI but I'm stuck with a soft-bricked phone.
Help would be very much appreciated!

Whats your original DPI. And i will be needing the update.script and updater.script both ftom any flashable zip your device support
