Found this thread while searching for stuff related to symlinking. Sorry you haven't gotten a reply mate!
If you have a ROM with init.d support (or add it to your existing ROM using something like Pimp My ROM), you could use scripts to run it on every reboot. That's what I'm doing!

Hello, totally forgot about this post.
I'm using directorybind at the moment, it's not exactly symlinking but it works.

Busybox

is there a way to install busyboxy with ClockWorkMod recovery?
Well most roms have a version of it what rom are you running?
Sent from my SPH-D700 using XDA App
no need to install busybox unless your on an older rom/kernel, but for whatever reason you need to there is one in the market
I am running the epic experience v1.2.06 and i have tried the one on the market and it always comes up fails
Try downloading titanium backup and go to the problems section and it will install busybox.
sent from the epic
tried that and it failed
Well I looked and the ee rom has busybox and just wondering what do you need it for?
sent from the epic
Metamorph keeps telling me I need to install it but the installer tells me its installed :-( what location shuld I pick?

Maybe it's already installed. Most of the ROMs have it already built in.

Click to collapse
you need to adb shell or run a terminal on your handset and create a link where metamorph is expecting to find busybox (or simply copy the binary)
i.e.,:
$su
#ln -s /sbin/busybox /system/bin/busybox
- or -
$su
#cp /sbin/busybox /system/bin/busybox
linking saves you the trouble of version mismatching, but some people seem to have issues with it.

[Q] Problem by flashing Wildfire use unrevoked3

Hello guys,
in the topics from the search my problem is not solved.I have buy a Wildfire with german Vodafone branding FroYo 2.2. Now i will flash the firmware using unrekoved3. But unrekoved doesn't flash my phone. It stopps by downloading the file and my mobile phone do not make any things. The driver package is installed and my phone is in the right modus to flash it. If i try to install a new Firmware with the RUU and the GoldCard method i become the error 140. I haven't any more Ideas what i can do. Can you help me? Here are many experts and i hope i get good help from you
Greetings
P.S.: Sorry for that bad english
You are probably having the same problem as my friend had.
Wildfire devices with a new Hboot can't be software hacked.. Yap.
But it's possible through some device that mobile shops should have.
Google your Hboot version and find out if rooting is possible for your device.
Hello,
thanks for your answer. I have read that my HBOOT Version can be rooted and on another thread in the internet I've read that is not possible.
I have tryed to root my Handy with a noob guide from this forum here D) but on the task where i push the m0td (or another thing with that name ^^) to SD Card the cmd says, that my System is read-only . What can I do to ignore this error?
Greetings and thanks for help ^^
I don't have too much experience with that but it probably has to do with mounting your SD.
Try to use these commands from adb before you push the file to SD (hit enter after each line):
adb shell
mount /sdcard
exit
if that won't work, google other solutions for mounting SD. Are you trying to do so in recovery mod? In that case you have "mount SD" option.
wait, you said System..
probably you need to use these commands from adb instead of the previous:
adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Sorry, but that don't solve my problem
I think the codes do not make anything. Because i seee the step and no anything else
OK..
You really should post your problem on Wildfire forum. Post your Hboot version as well.
There must be people there that will know the answer. Nobody else answers here, as you see.
Yes i think so. but i dosn't have enough permissions to post in this forum. I must have 10 posts
Yea, I know what you mean. I needed 10 posts for another forum.
Start posting "thanks" on random posts if you must heh.
Ok, then thanks for your help ^^

[Q] Android MID tablet no internal storage

Hi guys
I recently purchase an MID N900 android tab with ice-cream sandwich.
It already has root access.
i didn't have read/write access so i installed remount and applied it to my external memory card.
I also installed rom toolbox lite to increase performance.
After I rebooted my device , the internal memory shows 0 and now i can't install any apps besides the terminal.
I don't know which app caused this issue but i think its remount.
I also can't access recovery mode.
I did a factory reset and it didn't help.
I don't know if this is of any help but every time i restart the device everything goes back to factory settings. It shows you the guide
when you start your device for the first time.
How can i reset the internal storage back to normal
Any help would be highly appreciated
Thanks a lot

I found a solution, hopefully this can help someone in the future
The problem was i installed busybox using an installer which causing some file discrepancies.
To fix it :
1. Install Android Terminal Emulator, this app can be installed even if storage shows full.
2. copy /system/xbin/busybox to /system/bin, if busybox is installed the code is "busybox cp /system/xbin/busybox to /system/bin"
When I did the above, all my previous apps and setting came back to normal

Hi! I have almost the same problem. I follow your instruction - i've installed emulator but i cant gain access.It says "cp cant create '/system/bin/busybox' : Permission denied.
Do you know how i can gain access over it?
ps My case is the same like yours. I tried to new rom, but after that it appeared. I cant install busybox, i can use emulator only.
Hi
Firstly I think you made a typing error, it's system/XBIN/busybox not system/bin/busybox
Secondly as soon as you open the terminal type 'su' that will give you root access, then type the command in the previous post.
I'm not an expert but I will try to help if I can.
Let me know if it works

I wrote commmand "su" and successfully gained root access. After that typed the command like you and no errors appeared. But still I don't have internal memory (cant install any apps). Any suggestions?
psEven i cant download any apps from the market...

Fixing 0 bytes on internal storage on tablet
1. First Install root explorer! (Pro Much Better)
I found a solution, The problem was I rooted my tab then internal storage crashed.
To fix it :
1. Install Root explorer , this app can be installed even if storage shows full, it will directly install on your sd card or external storage .(its more easier if you download it to your pc then transfer it to your sd card
open root explorer find or copy /system/xbin/busybox then pastethis folder to /system/bin
2. Before you copy the /system/xbin/busybox to /system/bin, make sure or check the /system/bin is set to rw, if the permission of the folder is ro ( read only)set it to rw(read/write) for you to able to copy those files, it is needed to follow this steps for you to paste /system/xbin/busybox to /system/bin
When I did the above, all my previous apps and setting came back to normal.. it is important to read and analyze this steps carefully, I consumed 2 hours to solve this problem. But worth it !!

There two ways both work there are also other methods to do it in the forum
install a terminal from play store open it
check if you have busybox need to install that too
type su
click on the right chinese character as soon as the chinese root appear its the allow section
mount -o rw,remount /dev/block/by-name/system /system
cp /place/where the su file is/su /system/bin
chmod 644 /sytem/bin/su
mount -o ro,remount /dev/block/by-name/system /system
reboot
some thing can be done with adb shell
and as i said there are programs on playstore that do this easly as long as you have root
hope it helps

Before your answer I managed to swap the superuser apps just by installing the superSu as a system app and rebooting the system. So far everything is working fine.

Magisk and /Systempartition rw???

Hey, thank you!
Yes, I really have some very important questions for someone who knows their stuff!
So: I have an almost unknown smartphone, a Beafon X5. With Android 7.0.
A great device, just for one.. "Modder" like me, a bit problematic, because absolutely no custom software can be found for it...
But now I've managed to trying Rootaccess For the device.. With your Awesome app, Mtk Easy root and magisk.
My questions :
# can I somehow change the /system/ directory to rwx 7777 for me? Because now it doesn't work, just because of the systemless root. (at least I think) The chown/chmod commands Not working.
It will be" read-only file system" every time printed. I just want to replace the boot animation.
# Question 2:
Why can I only use after every reboot, mtk-Easy-root again from new, to activate magisk?? Why didnt work magisk, Although the SU is insatlled? Only if the mtk script has been run before, I can use the superuser in the magisk Manager Serve.
Have you an idea for this Problem?
Thank you, and best wishes from germany!

For question 1:
Android as a system (linux-like) mounts the system partition as ro (Read-only) by default when booting. In order to be able to modify it, you need to remount the desired partition as rw (read-write) as follows:
While being a root user (#) enter this command in adb or terminal on your phone:
Code:
mount -o rw,remount /system
To revert back to ro (you should do it after you're done), use:
Code:
mount -o ro,remount /system
For question 2:
That app is based on Mtk-su exploit. You can read an article from xda here. Basically, your device's bootloader stays locked, but root resets every reboot, because the attained privileges are only temporary. (su gets to run from /data/local/tmp).
Remember!!! You Bootloader is still locked, meaning AVB and dm-verity are still active. If you modify system (changing the total checksum), you will brick your device!!! And if you unlock the Bootloader, then what's the point of Mtk-su ..........
Hope I helped you somehow.
Schlank K:
Thank you, but I'm not a complete noobThank you, but I'm not a complete noob Thanks, really. But I tried these methods ed for a long time...
The same thing still happens, I mounted, there is no contradiction, but then nothing actually happened either...
Individual blocks can be mounted in the main directory, but not specifically the system/block. I actually only planned to do this stupid boot animation from the system/media folder. Delete/replace/rename/move zip, whatever, to finally get rid of the thing for my own ani...
And there it started. I've already spent several hours on the net to find a way. There are many options, but none have worked for me so far..
Looks like dm-verity is in effect. Disable it and then mount should work.

Hey, thanks
I've already tried that. Detects my system Not.
AVB ( dm-verity ) is bootloader related. You typically use Fastboot to disable it.

I've already tried that. My fastboot gets the same message. I have already tried the system block mounting, via dev/blocks/ but there I also get the read-only message.
Or mounting via busybox, I've already done everything.
I've googled a lot about it, and found nothing else that helps , otherwise I wouldn't have asked here on xda.
There are these read-only ROMs, how do I recognize them? Is ext4 not also read-only from manufacturer from
Thanks, guys
is your bootloader unlocked!?
you know disable-verity is adb applet, don't you?
you have been warned don't do this on locked bootloader. happy bricking..
btw there is such thing like magisk modules no need to modify system partition at all. just read the Magisk Developer Guides Module Tricks section
