[Q] chmod 755 doesn't work in adb shell: wifi broken - Samsung Galaxy 5 I5500

Hello, I have a serious problem.
I am using adb for hacking my Android Galaxy 5 smartphone.
Wifi got broken because I can't make file /data/misc/wifi/wpa_supplicant.conf executable.
Issuing chmod 755 have no effect, even after remounting the system as rw with command
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Consequence: Wifi is broken. I have no idea about how to prevent this behaviour of chmod. Can you help me?

Solved: I was confunding two files: wpa_supplicant and wpa_supplicant.conf. Sorry

how to replace framewrok-res.apk?

how to replace? by using metamorph? i did with root explorer and ended up with bricked x10 mini.
It's probably best to do it via ADB.
yes adb / shell is my favourite method
I use Root expl. only to rw mount /system partition.
How to do via adb?

0. Root !
1. adb push framework-res.apk /sdcard/fr-black.apk
2. adb shell
3. su
4. mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
5. mv /system/framework/framework-res.apk /sdcard/framework-resORIG.apk
6. cat /sdcard/fr-black.apk > /system/framework/framework-res.apk
7. chmod 755 /system/framework/framework-res.apk
8. sync
9. reboot
why cat and not mv/cp ? Because the file is created with "root" user and group and not "sdcard" group.
Means the framework file is first placed on sd card which i want to replace? Asking noob questions cause dnt want to install whole software again

Here, I'll try to explain what happens
1. adb push framework-res.apk /sdcard/fr-black.apk
-copies "frarework-res.apk" from ADB's folder and moves it to the phone's SD card, names it "fr-black.apk"
2. adb shell
-opens the linux shell on the phone
3. su
-goes into superuser mode, i.e. runs apps as admin if you're familiar with windows terms
4. mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
-remounts the /system folder on the phone so that it is read-write, allowing you to mess with the system files
5. mv /system/framework/framework-res.apk /sdcard/framework-resORIG.apk
-backs up the default framework-res.apk from the phone by moving it to the SD card
6. cat /sdcard/fr-black.apk > /system/framework/framework-res.apk
-copies the fr-black.apk from the SD card and puts it in the old framework-res' place
7. chmod 755 /system/framework/framework-res.apk
-changes the user permissions for the new file

accually you could just us this

should work just fine without the -t yaffs2 i know it works on the samsungs

[Q] AdHoc Mod on HD/HD+

Is it possible to do the AdHoc modification on a rooted HD/HD+ as documented in the below thread...
[FIX] adhoc wifi Nook Tablet 0.6.10 tiwlan0
Or will it cause the bootloop/reformat issue?
PokrTom
Unfortunately, the answer is no.
After waiting for an answer from those who had more knowledge then myself I decided to make myself the Guinean pig, Did a Timbuktu backup and made the mod, rebooted and watched my Nook reboot eight times and reformat.
So the short answer, at least for now, is no.
Which sucks because I make a regular use of using my phone for net use, so I hope something comes along soon.
Interim fix?
I tried seeing if there might be an interim fix option and I am hoping there is someone with more expertise that might be able to help me here.
Here is my thought.
When a user wants to use An Ad-Hoc connection they would execute a script like the below...
Code:
mount -o remount,rw /system
chmod 777 /system/bin/wpa_supplicant
cp /system/bin/wpa_supplicant /mnt/sdcard/mods/wpa_supplicant.nookhd
cp /mnt/sdcard/mods/wpa_supplicant.omap4.adhocfix /system/bin/wpa_supplicant
chown root /system/bin/wpa_supplicant
chmod 755 /system/bin/wpa_supplicant
mount -o remount,ro /system
When they were finished they would then have to run a clean up script like this...
Code:
mount -o remount,rw /system
chmod 777 /system/bin/wpa_supplicant
cp /mnt/sdcard/mods/wpa_supplicant.nookhd /system/bin/wpa_supplicant
chown root /system/bin/wpa_supplicant
chmod 755 /system/bin/wpa_supplicant
mount -o remount,ro /system
I used G-Script for the above steps for ease of use.
Obviously, they could not reboot while utilizing Ad-Hoc
Whats needed is the wpa_supplicant file to use for the fix. The one utilized by the Nook Tablet above does not work. The process itself has promise as I have tried it and while I could not get it to work, it did put the wpa_supplicant file to use and it did not reformat my device after I power cycled my device.

I have an unlocked AT&T Atrix (MB860) with GB 2.3.4 and I have exactly the same problem: that the /system folder remains stubbornly read only, no matter what I do. I have tried a lot of the methods I found in the forums and elsewhere, but to no avail. I suspect the only effective solution will be to install a full .sbf image with an already rooted /system folder, but that will be the very last resort. We are not the only ones with this problem; I have seen the messages of a few others. On some phones, the easy methods just do not seem to work.
So, have you, or others, found an acceptable solution other than to install a rooted sbf image?
I'm a Sony user so not sure if this applies too but is USB debugging on?

[Q] Help! bricked kindle fire hdx 8.9, rest on colored "kindle fire".

My Kindle fire hdx 8.9 worked normally since I bought it. Yesterday I remove the signature to install google service, and the wrong was it can't restart and I reset it to the factory from recovery. Now it still rest on the colored "kindle fire". But it seems some processes have been loaded because the MTP devices can be found in PC and the adb mode seems work normally. I think some steps losed in the boot. Can I recover it by adb mode or other methods? Thank you.
I reset it to the factory from recovery.

Yes , the root tools can work. Input su and display "[email protected]:/#". It seems something different with the bricked in forum.

Good.
You need put back original files:
services.odex and any others that you changed
like this:
Code:
adb shell
su
mount -o remount /system
adb push services.odex /data/local/tmp
chmod 755 /data/local/tmp/services.odex
rm /system/framework/services.odex
cp /data/local/tmp/services.odex /system/framework/services.odex
chmod 755 /system/framework/services.odex
reboot
or simple
Code:
adb shell
su
mount -o remount /system
rm /system/framework/services.odex
adb push services.odex /system/framework/
chmod 755 /system/framework/services.odex
reboot
