[Completed] Temp rooted phone but no rw on /system - please help! - XDA Assist

Hi all,
I have gained temp root access on a japan phone, able to obtain rw access to all files & folders except /system. Edited default.prop file on ro.secure and ro.debuggable to 0 & 1, did setenforce to permissive but still unable to write on /system getting mount: permission denied, is there any advice anyone can give please?
On a seperate issue, this phone does not have fastboot or recovery mode, attempted to dd a modified boot.img to the dev/block/xxxxxxxxxx folder of where the original boot.img was resulting a bootloop, wondering under normal circumstances when there is no fastboot or recovery mode, dd a boot.img should achieve the same flash result of using fastboot?
Thanks in advance!

What about using another root explorer app?
(E.g. Root Explorer, ES File Manager, etc.)
Keep in mind that you have to enabe root features in the explorer app itself and grant it root permissions in SuperSU app.
In some root explorer apps, you have to mount system partition as R/W (read/write) before you are able to change something in there.
For further questions, please ask in the Galaxy Star Q&A, Help & Troubleshooting forum.

Ok, here is a guide about adb shell: [GUIDE][ADB]Easiest How to use adb, logcat, etc for noobs and newbies.
And here are some useful shell commands: [GUIDE] Basic Unix/Linux command to use with ADB SHELL.
Including chmod, example "chmod 755 /system/tmp/root.sh".
Make sure to got into root mode with "su" before.

[Completed] Set wrong value in build.prop, stuck in boot

Here's the SE link with my issue.
https://android.stackexchange.com/questions/131577/cannot-remove-rename-move-build-prop?newreg=528098aed3b24c58a1949dbf850b4387
But I think you guys are able to help me better because I think it's a device/huawei kind of thing, not generally android.
Anyhow, what I did aside from that SE link...
I've downloaded a "template" from here http://forum.xda-developers.com/showthread.php?t=732957, update-apps-signed, and done what he said, afterwards I resigned the zip with SignAPK.
Then I went into recovery and applied update from sd card, but I get the same error every time...
-- Installation /sdcard ...
Installation aborted.
I googled some more and from the looks of it I need an OEM key from Huawei to unlock the bootloader and flash CWM before I can proceed. I seriously hope I don't need to do this.
So here's what tools I got:
ADB accessible phone in normal boot. Phone appears to work, the interface just won't load.
Android system recovery 3e in recovery.
This is incredibly frustrating as I know just changing one bit is all I need to get my phone working again.
Anyone got ideas how to proceed?

Hello,
Since adb works for you. You can try these (One by one)
Code:
adb root
adb remount
adb pull /system/build.prop
Make the required changes which you messed in build.prop
adb push build.prop /system/build.prop
adb shell chmod 644 /system/build.prop
adb reboot
Alteratively, you could register for a XDA Account so you could reply to the threads in the forums as well as get expertise help

adb root -> I can't do that, it says it cannot run as root in production builds.
adb remount -> Not permitted
adb pull /system/build.prop -> This works, that's how I got the build.prop
Make the required changes which you messed in build.prop -> Donezo.
adb push build.prop /system/build.prop -> Read-only file system
adb shell chmod 644 /system/build.prop -> Read-only file system
adb reboot -> Works fine
And yes, I'm op, no idea how to claim the thread or change my name... xda said the mail address was already taken with this username.
I've already tried this as seen in the comments.

Hello,
You need to get adb root working, Try running it as administrator.
If still doesnt work, then give a try to this
-Vatsal
I need root access before with ADB if I want to change that, which I can't get. To enable root access with ADB I need to have acccess to my device the normal way and edit the file with something like root ES Explorer. This is impossible as my device is soft-bricked. That's what I think, unless I'm overseeing some things?

Hello,
Well, you edited build.prop and saved that so that would mean you were rooted? Isn't it?
ADB commands work without root. However the /data partition is only accessible by rooted users* and while /system can be read by anyone, it's a read-only partition and root is needed to remount it as writable.
-Vatsal
I did that before it was soft bricked with SuperSU and ES Xplorer. I don't know how to use SuperSU with ADB. su -s and su overall appear to do nothing.

[Completed] Unknown Device - Trouble Shooting

I'll try to make this as short and concise as possible as the wall of text may crit readers eyes. The device I have isn't your standard tablet, it has no standard manufacturer so no support or stock roms. I am quite novice.
What we know:
Android Version 4.4.4
Kernel Version 3.0.36+ [email protected] #876
Build Number rk3188-eng 4.4.4 KTU84Q
What it is running(was) is very basic, I rooted it and went to install TWRP via the APK installer which is where it all went wrong. Due to the lack of knowledge of the device I installed what I thought would be a similar enough device to not brick the device. Once the device restarted it would no longer boot into the OS, so I went into recovery mode (Dead android) however there are no options or access here.
Moving into ADB, the device does show with a bogus serial.
Code:
0123456789ABCDEF recovery
I can push and pull data, however other commands such as
Code:
adb reboot sideload-auto-reboot
results in cmd to permanently hang.
Shell commands all return with not being found.
Code:
#ls
/system/bin/sh: ls: not found
#
I would love to either get her back up and running or completely install a new rom. Thoughts comments and concerns are all welcome!
