Deleted Build.prop, now it copies to system root but wont show up !

Dear All,
First thankyou so much for the great forum we have here, I am using Huawei Ideos u8150, the fone is network locked so I played around, being a total noob I started with installing sdk, and rooted my fone using z4root, rooting was successful
No when I try to copy a modified build.prop to the systems folder in root explorer, the file is copies but is not visible, also I have deleted the original build.prop & I am afraid to reboot the fone,
can restoring the fone to factory settings solve this ? also how come I copy the file to system folder, it gets copied and I still cant see it ?
I have tried pushing the file using ADB command line but the device refuses to mount (persmission denied)
I would really be thankful to anyone who can guide a noob like me, if you dont this forum has enough reasons to love it already,
cheers !

Moderators if by any chance I have placed this query in the wrong part of forum, please let me know in which part I should raise it, thanks !

In the top right hand corner or left it should be a r/o button. If you push that to r/w which is read/write you will be able to copy the bp correctly. Don't forget to mount as r/o which is read only before you exit RE. Then reboot. If you made a backup which you should have done before modding the bp you will be ok to reboot. If anything goes wrong just do a restore. Also you can Redownload the current rom your on to your cpu. Then extract it to a folder on your desktop. Then browse threw all the folders untill you see the stock build prop. Copy&paste it to your sd and that's your stock build prop. Hope this helps. Good luck

thanks for the kind help, I have tried doing that, I have rooted it, the I click on the r/o button and then I did copy the new built.prop to systems folder, the copying process completes, doesnt report any error but still there is no file visible by the name of built.prop, I just cant find it, is it hidden ? or is it not being copied in the first place ? & thanks I would try to extract the stock built.prop, and copy it to the folder but I will do it as a last option till I dont find something else,
thanks a million for the help, would apprciate if you can point it what I am doing wrong

EFS Folder backup?

OK so after doing some research about random rooting tips and apps and what not i stumbled on a thread on xda and part of it said the following:
"EFS Folder (Important)*Ok this is more of a you must do and not a what you can now do. So the efs folder is a very important folder within your android system that contains infomation like your IMEI number, and just well important infomation trust me it's important. When people start to mod their phone such as flashing roms, kernels e.t.c, this folder can become corrupt, making you phone usless. So backing up this folder is important and their is an easy way in which you can do this, a more user friendly way using a great app by hellcatdroid. You can get this app from google play*here(ktool), and it will give you all the tools to back up the folder. I will also include a guide on further reading for you to have a look over, so please backup your efs folder."
Everyone was mentioning the importance of backing up this file, so I was gonna try. I looked up the app but I read the description and its only compatible with some devices. Would there be a way to backup our blaze EFS folder to SD card or something?
Thanks in advance for even reading this lenghy question

For my build 1 of dknight I had back up efs as a step but everyone was confused so I took it off lol the easiest way to do it is use root explorer and copy the whole efs folder to ur sdcard and that's it
----------------------------------------------
If helped don't be afraid to hit the thanks button it doesn't bite lol

Thanks ill do that then. I hate questioning you since you obviously have more knowledge on this topic, but I also read that wasn't the best way because it didn't copy permissions or something like that?

It's not the best way but it is the easiest way like I mentioned but if you're good with adb you can pull the folder through recovery and that way I think perms stay...either way it's better to save it like that then to not save it at all you know
----------------------------------------------
If helped don't be afraid to hit the thanks button it doesn't bite lol

Use Termimal Emulator or ADB (as su) and run this command:
busybox tar -cv -f efs.tar -C /sdcard /efs
Don't miss any spaces and remember that the command is case sensitive. You should have a file called efs.tar in /sdcard when the command completes. It should take under a second.
Using tar will preserve permissions. Just remember to pull the efs.tar file ASAP as it saves to the internal SD... if you leave it on the device there is the potential that the file will get wiped if something happens to the device.
Might be a good thing to incorporate into the update script ... automatically back it up just in case.

[Q] Anyway that I can recover my phone???

Hello,
I have LG Optimus Elite Android 2.3.7...it was rooted...
I accidentally deleted /system/bin/sh...gee..oh my god..
The problem is that I am not even able to adb to my phone now..
If I do adb to that phone, it is complained about /system/bin/sh doesn't exist something...
Gee...........
Obviously, factory reset didn't help cuz it didn't restore the sh...
What would be my option ??
When I just reboot my phone, it is just stay "Welcome to" screen...Even though I touched the begin, it won't go next..I think because..
my /system/bin/sh file is deleted..so my phone can't execute anything from the phone shell..
What would be my option to recover my phone?
Please help
Thanks,

Get a copy of sh and
> adb push sh /system/bin/
But /system is read-only so you need to mount read-write. But you cannot because
> adb shell
Cannot execute sh because it is not there.
You need to restore from nandroid backup. Failimg that, restore back to stock with Odin.

Thanks for your suggestion.
BTW, nandroid backup -> I don't think I can use it because I don't have original backup rom?
Odin -> does this also work for LG phone?

No, you can't use nandroid backup. A nandroid is an image file of your system partitions. PC users typically know this as ghosting or cloning. To linux users, it's just a dd. You create the image yourself from a working copy. You don't need the original ROM. You can make a backup of your /system partition (nandroid) any time you have a working copy.
PS I'm an idiot. LG was literally the first thing u said. And you are correct. You need to use LG Flash Tool.
See 1942836

Unfortunately, 1942836 is not the same model I have.
I don't think I can use that instruction.
It really makes me crazy since I can't use adb at all....
I tried creating update.zip and put it in sd card to install..however, as you may know, signature verification failed.
if I could get key file to create signed zip file other than test one, that may work.
Is there anyway I can bypass the signature verification??????

Can't you reflash your system?
I think you need /bin/bash for adb to start, so without it, you can't push anything from your computer to your phone i guess..
What bootloader do you use?

Obviously, before happening this issue, I was able to use adb...
And..now..if I issue adb, then nothing shows up in the list of devices attached section...I guess because it can't communicate somehow with /system/bin/sh I just accidentally deleted.
I know that I can use Odin to install CWM for Samsung phone....I just found that there is LG Flash tool program on the internet does simialr thing like Odin for LG phone..however, I am not sure where I can find the dll that I can use from LG Flash tool program.
Any idea?

You will indeed have to reflash your device, as you don't have any other way of putting the bash binairy back.
I guess, as you are rooted, you know how to reflash your device. If you don't, search the forum

I have the same problem, I deleted the partition /persist and now does not turn on Wi-Fi, my folder has only one binary, do not know what the solution.
Edit: We need a binary and a folder in that partition, I guess flashing one. Zip partition be solved, just do not know how to do it, I need the files to assemble. I do not know if we can assist in that, since I have already used the RSD lite for flashing full firmware and nothing, you can not, brand error...

Any Terminal Emulator/SSH client (connect to local) will allow you to type chmod (modify file permissions)/chown (modify file ownership) commands - you need to be comfortable with using command line interface in Linux.
Alternatively, most file explorer apps (like ES File Explorer) will also allow you to change file permissions/ownership.
You will have to allow root access for the terminal emulator or file explorer.

I have the same problem. It's possible to have the solution step by step please?
I have Windows and the official ROM is in Motorola Razr HD (4.1.2).
Where to copy the file?

Wifi fixation
Hello to all

Also went nuts with formatting and I formatted both Persist and Firmware, now wifi does not work. I have the pacman rom, can the experts please give detailed steps, sorry really a newb...
I do have Terminal Emulator and File Manager (both came with Pacman Rom)
1. Am I supposed to create a folder called persist and move the bin file in there?
- This did not work for me
Please Help, thanks!!!

Got it to work, here are some instructions that worked for me, used the bin file as opposed to zip and root explorer made things easier...

I forgot about this thread and somehow learned how to use it by trying xD Thanks anyway!
And also I suggest to use Root Browser and change permissions there.

Recovered my phone
I had this issue as well. I'm posting my results here in hopes that it helps someone somewhere who encounters the same issue.
I have a XT925 (Motorola Razr HD) with Clockwork mod recovery, unlocked bootloader and Slimkat 4.4.2 Build 3 Rom. I decided to update my bootloader to 4.4 compatible version, but in order to do that I first needed to downgrade to stock 4.1.2 I follow the stepshere for my device.
I somehow ****ed it up with an old version of RSD lite and after much work with command lines, flashing different recoveries, backups and shifting through kitkat versions I ended up with out wifi no matter what rom i was on. I flashed back to stock with RSD -no wifi, restored a backup -no wifi, upgraded rom version -no wifi. I cleared partitions, wiped numerous times.
To make a long story short, the solution in this thread worked. Simply put:
Ensure you have root access and a working ROM.
download a copy of the mentioned wlan bin file (mirror at the bottom)
get your hands on es explorer
connect your device via USB
place 'WCNSS_qcom_wlan_nv.bin' file somewhere where you can find it easily using ES explorer
enable root add on for es explorer, its in the settings list
move it to /persist, it's in the root.
hold on the file and select 'properties' or something to that effect.
change (or rather ensure) the permissions are READ & WRITE only for both owner and group (-rw -rw ---)
underneath permission you should see owner: set that to WIFI
exit and reboot
I know this is just reiterating what xXLuHXx, and many others have posted, but i wanted to ensure it was clear. You can do this via command line with adb I'm sure, but this is a fool proof way, and it worked for me.
Here are some links:
Es Explorer apk
Mirror for WCNSS_qcom_wlan_nv.bin (not sure if its the same link as the others have posted, but it's here)
Hope this helps someone

Download android sdk, install it as google tells you. Go to the folder your build prop is at, hold shift, press the right mouse button, press on open command prompt. Type this in it:
adb shell
su
stop
mount -o rw, remount /system
push build.prop /system/build.prop
mount -o ro, remount /system
reboot
If you cant do that, you can always reflash the firmware
