Hello guys,
I been trying in the little time I have to get rid of Fota file by using ADB but have not successfully been able to delete those files. I am not quite sure what is the process to do it but this is what I have been trying.
Open CMD
1- go to platform-tools folder on CMD
2- Type adb push c:\directory\fota_delta_dp1\ \data\fota\
3- repeat for second fota file.
It says that failed to copy c:\directory\file\ \data\fota\ since is read-only
How do I make it "writable" or what am I doing wrong,
I wanted to mention as well that my phone is rooted.
Find Root Explorer. Install it.
Change the file system to R/W.
Then, navigate to \data\fota and delete the files.

However you want to get root shell and do:
# cat /dev/null > /data/fota/fota_delta_dp1
# cat /dev/null > /data/fota/fota_delta_dp2
Well thank you for your advises. I ended up using "Super Manager" checked in setting "Use root function" went to the folder were i had the files alreadt unzipped and copy them over to /data/fota which replacea both of the fota files. Rebooted the phone and had 280mb of available storage.
When i get home i'll make a tutorial using Super Manager.

Hi I have a problem: i had a samsung galaxy s 9000. I had it for a year: i tried many roms on it ( cyanogenmod, miui, ecc ). I used ,also, a tool to backup my EFS's galaxy; this tool is here: http://forum.xda-developers.com/showthread.php?t=1138873
Now, I have a nexus s i9023 slcd. And here it is the problem: now, the linked tool to backup my EFS doesn't work. I root my nexus and the bootloader is unlocked. I used 5.0.2.0 CWM. The rom is 2.3.6 STOCK - GRK39F. I used windows 7 32 bit and I start the prompt command as Administrator. When I write "efs_backup.bat" I can read this:
http://imageshack.us/photo/my-images/267/immaginegsj.jpg/
Is it possible resolve these PERMISSION DENIED'S?
I ,also, type ( in the APP terminal emulator ) :
su
chmod 777 /efs
exit exit
but I don't solve the PERMESSION DENIED problem.
I hope you will help me.
I can't post in the "tool EFS backup and restore" thread (http://forum.xda-developers.com/showthread.php?t=1138873) because I'm new member
There's no reason why you can't copy the efs folder manually. Copy it into your sdcard and then copy it into your computer for an extra backup

I don't understand why the xda efs backup's tool doesn't work in my nexus s: it was ok on my galaxy s.
I post here to solve this problem: please, help me. Thanks.
I had trouble with that tool too. I remember i got it working, i think by moving the script into the sdk tools folder, and make sure USB debugging is selected.
Still, i don't think it is worth the trouble. You could just copy the folder like i suggested before, which is easier. Or you could install Team Win Recovery Project which can backup your efs

I read that TWRP recovery should create problems on efs folder during its backup/restore. Do you use it or cwm 5.0.2.0?
I use team win. No problems with efs when backup runs.
I haven't tried restore yet, but they assure it works.

I changed my stock rom with miui and, now; the tool is working !
Dear all,
it is time for me to pay back. I have found a lot of information and tips from this forum. However, when I bricked my device by erasing the efs folder (trying to install Linux on my N8013 Tablet) I only found partial fixes, like creating the directory FactoryApp and the file factorymode with ON inside it.
I have searched forums and forums and I could not find a comprehensive answer. I tinker and tinker with my device and at last I recovered the efs folder and it does not get wiped out on boot.
Before today, I had to boot my Tablet and create the FactoryApp and file factorymode with ON inside it to make my Tablet not showing the Factory Test have stopped and to show the lock screen. Now all is back to normal.
When in recovery mode CWM the efs would not mount!!
Thanks to too many people, I have been visiting so many sites I do not remember the names of all!!! Thank you all!!
Ok, this is the procedure it worked for me.
1.- Install CWM recovery in your rooted tablet.
2.- Install ADB in your pc to be able to communicate with the tablet via com window. Install busybox as well.
3.- google a nv_data.bin file if you find one. I found one. I could find the download link if someone ask for it.
4.- BOOT your Tablet in Recovery mode push both the power and the volume up button (the farthest to the power button). When the First letters appear, release the power button, not the volume up until entering in recovery mode.
5.- Go to your PC, connect the USB cable to your tablet and go to C:\Program Files\Android\android-sdk\platform-tools>
6.- Type adb shell and hit return
7.- if you see # good, you have access to your tablet. Do not type su because does not work. You are root (I assume).
8.- type busybox df -h and check you do not have the efs mounted. In fact it does not even appear.
9.- Try to mount mmcblk0p3 (mount -w -t ext4 /dev/block/mmcblk0p3 /efs ) YES 0p3. I have found a lot of forums saying it is 0p1 but not in the Galaxy Note N8013. I tried with the 0p1 and did not work.
10.- Of course did not mount!!! That is the error. So we have to....
11.- Now try to make that partition, by typing mke2fs /dev/block/mmcblk0p3
12.- Now try to mount it again by typing mount -w -t ext4 /dev/block/mmcblk0p3 /efs It worked!!
13.- Now you have to keep the downloaded nv_data.bin file in the root of your sdcard, and a text file named factorymode with the letters ON inside.
14.- do busybox ls -ltr and you will see there is a folder called sdcard -> /data/media
15.- create a folder inside the /efs/ folder named FactoryApp
16.- Copy the factorymode from the root of your sdcard to the /efs/FactoryApp folder by typing: busybox cp /data/media/factorymode /efs/FactoryApp
17.- Copy the nv_data.bin from your sdcard to your efs folder by typing: busybox cp /data/media/nv_data.bin /efs
18.- Now change permissions to all those files inside efs with 0744 by typing: busybox chmod 0744 /efs/FactoryApp/factorymode
Do it with all!!
19.- Now change owner of the directory efs down with: busybox chown 1001.1001 /efs (I think there is a switch to change all at once, but I forgot so I changed all directories and folders inside efs.
11.- in CWM go to advanced and fix permissions.
12.- Boot in recovery mode.
13.- Try to mount efs partition and it works!!! Check with ADB that all your files are there and a lot more.
14.- Reboot the Tablet and the efs is there for good.
15.- Install in your computer EFS Pro and do a backup ofthe efs folder.
16.- I am sure the IMEI is not the good one, but the N8013 is not used as a phone anyway.
Please be careful and backup all the partitions of your tablet before doing this. It worked for my N8013 but I do not know if it will brick yours or if you have another model.

hey man,
thanks for your tut, my device is n8000 and it doesn't boot due to me installing tablet rom by mistake anyway, i did everything you did except i used .jar root explorer from here in the forums and transfered the files after i mounted it and choose 0p1 , im not sure what went wrong but anyway after that i used the commands to give permission and owner like you but they get wiped after restart, any ideas ?

Geez, I am far from an expert here. What folder/partition gets wiped out? efs? Because searching the web I realized the 0p1 is /system (maybe I am wrong) and 0p3 is /efs.
Did you try " mke2fs /dev/block/mmcblk0p3" or with 0p1? What happened?
Did you try "-w -t ext4 /dev/block/mmcblk0p3 /efs It worked!!" What happened?
I think, those are the most important steps, because it allows you to mount in recovery mode the /efs partition.
Later on, an important step is " cp /data/media/nv_data.bin /efs" but I do not know why?
Of course changing owership...
I am very sorry is not working for you. Please, try it again. I know what frustrating it is!!! I have had my tablet broken for more than two months and by trial and error finally got it working. I could send you the nv_data.bin file if you wanted. However, it will set your serial number to 000000 and I assume a wrong IMEI. But I do not use my tablet as a phone anyway.
I hope it helps!! Thanks for reading!!
nv_data.bin please help!

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.

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).

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...

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
