So I upgraded to 6.0 but can still browse and copy/delete from but not copy to /system, no supersu and it won't let me install it. Is this normal?
I just want to know if every one can access the /system on 6.0 cause I thought you had to have root to get to it.
No one?

Hello fellow XDAers,
My wife replaced her Samsung Gravity Smart with the T-Mobile MyTouch Q, AKA the Huawei U8730 (not the older LG C800 model w/ the same name). She gave me the task of cleaning the junk APKs off of it to de-clutter it.
Rooting the phone was the first task. This method worked perfectly for me without any fuss (the app will return error 64, but after installing Superuser and rebooting, I had root access). I was able to use Titanium to remove much of the crap ware, but the most annoying bits gave the error "cannot find APK." Weird.
After digging around, I took an inventory of the apps in /data and /system.
The T-Mobile junk wasn't there.
I threw busybox on the phone and used the 'find' command, and I found where the apps were hiding: /cust/t-mobile/us/apps, which is a loopback-mounted ext3 partition. I tried to remount it read/write, but got 'permission denied' error. I figured something had the filesystem locked, so I ended all the apps that were running and tried again, but no luck.
However, I was able to remount the volume that held the ext3 image file read/write. It mounts to the /.cust_backup directory.
IMPORTANT NOTE: For those who will be following these steps themselves, at this point you will want to make sure to go into the Applications manager and uninstall any updates downloaded for the crapware you are going to remove. I will explain why below. It's not absolutely critical, but it will save you some head-scratching.
I remounted the partition read/write, grabbed the image file (located in /.cust_backup/image/cust.img), and uploaded the image file to a linux server.
On the linux server, I mounted the image, nuked the unwanted APKs, and unmounted the filesystem.
I created a backup of the original cust.img file, then overwrote the one in /.cust_backup/image
Last step was to reboot the phone, and most of the junkware was gone.
Here's where the head-scratching came in. A couple of the apps were still there, and I didn't know why. I double-checked the phone, and the APKs were in fact deleted. Then I realized: the app had received an update and I was seeing the update. When I uninstalled the update, the uninstall "failed" but the icon still disappeared. However, I had to reboot the phone again to fully remove it.
So, here's the process in a nutshell:
1. Uninstall all app updates for the crapware you plan to remove
2. Root the phone using This method .
3. copy down /.cust_backup/images/cust.img
4. Using a linux system, mount cust.img as a loopback device, then delete the unwanted APKs (they will be in t-mobile/us/apps)
5. Unmount the image (this writes your changes back into the cust.img you mounted in step #3)
6. On the phone, remount /.cust_backup r/w
7. overwrite /.cust_backup/images/cust.img with the modified version
8. Reboot the phone
That's it! Enjoy your uncluttered phone!
I know it's been a while since the original post, but I was wondering if OP has had any problems with the phone since then, or if anyone else has tried this with the Huawei u8730 and had success. My wife also wants all this crap removed from her phone, but she would probably murder me if I bricked it in the process.
Thanks!
Just on a side note here as I'm still using this device. How did you get around the non-working tethering on this device? Both the USB and Wifi hotspot won't work unless you've subscribed to the T-Mobile Smartphone Mobile HotSpot app option on your account? Mine is unlocked and being used with another carrier, but only recently wanted to tether to it so I can't figure out how to correct this one. Also still looking around for any working custom ROM for this. Thx.
Hi,
I updated my G Pad 7.0 Wifi (V400) to Stock 5.0 Lollipop yesterday via OTA and everything looked fine.
I have 2 users on my tablet (one - main - for me, the other one for my girlfriend) and I noticed that the secondary user is unable to mount SDcard at all, so my gf cannot use a big part of her applications.
I already tried rebooting, mount/unmonut and remove/re-insert sdcard, next step should be a WIPE, but I'd like to know first if it's a bug or a Lollipop "security feature" or something.
If you have an updated v400, can you have a try?
Thank you very much!
Davide.
I have a V410. On stock LG kitkat no normal users are able to write to the microSD, not even the primary user. I have to enable root access to even write files to it with a file manager. No lollipop yet on the V410 (not stock anyway).
I know its not exactly what you were asking, but just thought I'd share it. LG definitely has sdcard access messed up in their roms for this tablet line, at least that has been my experience. TWRP, AROMA File Manager, and timmytim's CM12 can all use the sdcard just fine.

Jason, thank you for sharing your experience but I'm facing a different issue. I try to explain it better.
With 4.4.2 I was able to move some of my applications to the sdcard (Settings --> Applications --> [app name] --> Move to SD card). Doing this with my primary user allowed me to save some internal storage space and all of my users could play games that were previously moved to the sdcard.
Now with 5.0.2 everything is fine with my primary user, but with my second user I can't see sdcard at all... I see all my moved application in the drawer as a "generic Android icon", and if I try to launch them I get the "SD card removed" popup error.
I know that in a major upgrade like Kitkat->Lollipop a clean installation with full wipe is required, but I asked if someone with Lollipop could try my same scenario in order to check if this is a common Lollipop "feature" (making a wipe useless) or just a bug due to messy upgrade.
Thanks in advice to everybody for your help.
Just to share my personal solution with all of you: I tried a full wipe with no results. At the end I decided to switch to CM12.1 and this solved my problem.
I have Pro 8.4 with KitKat 4.4.2 . I have a full access of SD card on system's file manager, but like on WinZip or 7zipper, I don't. Same for other programs. Now I wanted to download a torrent with app uTorrent and it failed with error "Permission denied. (ReadToDisk)". Maybe somewhere is like on Windows "Run program on Administrator mode"? Or maybe something that will give that permission. Not rooted, and not going to do that (maybe when warranty ends).
Unfortunately you need root, it's actually a bug in the kitkat android sources that blocks sdcard write access (though it is fixed in Lollipop, unfortunately Samsung hasn't release LP for our device yet), the only way to fix it is with root since the file that needs modifying is on the system partition...
But, if I would to upgrade to Lollipop (if we ever have it) then it will fix this thing?
yeah
Check my thread here: http://forum.xda-developers.com/android/general/write-data-to-external-sd-card-kitkat-t3248220
In most cases (with many apps that write data, like downloads), you can, in fact, write to the external SD card in KitKat, without root.
Hi Folks
on 3.1.3 I had downloaded the OTA update via the ROM-inbuild functionality (Settings->System Update).
But, instead of using following the ROM-update function I decided to download the full 3.2 ROM and update via TWRP, as recommend on several locations.
Things are running fine now under 3.2, but System Update is constantly (after each reboot) nagging to update the system - I assume because it sees the update file somewhere and wants to proceed.
Does anybody here know where to look for this file ? I searched under a number of locations, so far without success.
Your help is much appreciated, thanks
Axel
You'll find the update in the internal storage under Android/data/com.oneplus.ota/files/.OnePlusOta (beware, the last one is a hidden folder!)
In my case, the file was inside the
Code:
.Ota
directory, which is root folder. Note that is a hidden directory, so make sure your preferences are set to see hidden files.

MM and Samsung roms fully support reading and writing to the sdcard. All that is required is for the app to ask for authorisation.
If it doesn't ask it's a bad app.
ADM also works fine with MM and sdcard.
