You could nandroid backup it, extract the image and zip & sign it up.

i know about nandroid but how i extract the image & zip? and how do i sign it? is there any tut that i can follow & learn?

.img file is a zip file (more or less). Use 7zip for that.

You could use dxisida's android kitchen to do all tasks, you put the system.img and boot.img in the 'original' folder and then make it a update.zip rom through the kitchen.

thanks all~! once my xtc clip arrived will try to do it. still waiting T_T...

Help with a chinese model phone, A101, deleted /system/bin/sh..

Hello all,
Firs I like to apologies if I've posted in the wrong section of the forum.
As the title says, I have a Iglo A101 with GingerBread 2.3.4 phone and I accidently deleted the system/bin/sh file.
I was searching for a2sd and I downloaded it, but when running it, instead of pressing 1 - "install a2sd" I pressed 2 "uninstall a2sd", by mistake, and by the time I realized the sh file was deleted. Now the phone is no longer rooted and can't be rooted and also my Wi-Fi doesn't work anymore.
I've search the net for answer but I can't find a solution to this type of phone.
Could someone help me fix this or at least get the Wi-Fi working again?
Thanks in advanced...

OK, I've manage to contact the retailer and he gave me what appears to be the all system files, as now I have a rar containg system.img userdata.img recovery.img etc etc. How do I install this files, because he doesn't appear to know either. I tried from the recovery mode using install update.zip from sdcard but it give's me invalid OTA package and I can't find an answer on how to flash a img file from recovery mode...

Does the device have fastboot? If so the files need to flashed using fastboot. The command is fastboot flash boot boot.img
Fastboot flash system system.img.
If your device does not have fastboot then you will need to extract the system.img and make a flashable .zip so you can flash through CWM or whatever your recovery is. If you are using stock recovery then I eexpect you will either need to find a solution or send it off for repair. I will have a look into helping you get your device back up and running but I cant promise to succeed. Give me a few days and I will report back with any solutions or info to get you on your way to fixing your device.

Trying....

hi
i had similar problem on this device a101 i did not delete any folder but by rooting the device my wifi and Bluetooth stoped working.i solved the problem by the factory menu.....have you tried it?

i did factory reset, but since there a system file missing it doesn't solve it..Can't there be a way to create an update.zip package with the sh file and then apply like an update from recovery? I've been trying to understand what does invalid OTA package mean, I think if that would be solved then I could easily put the file back...

i think you need spb launcher
i have to admit i used it only ones before for china 5388 there i needed com + usb cable here you need just a normal cable us the boot on this phone is different i have all you need give me email i will send to you. i have scater for a101 file too.i never used it but i have.Us i said my phone work ok after reset from factory mode

still nothing?

If you have the system.img image, you can try to flash it in the phone with SP Flash Tool,

[Q] Wi-Fi not working

After flashing stock ROM on my Moto G I was not able to use Wi-Fi, it does not turn on. So I tried some other ROMS from various countries and nothing. However when I flashed the Nexus G - beta 4 custom ROM (http://forum.xda-developers.com/showthread.php?t=2606943) I got it working again.
Can someone please explain what is happening, and help me?

Solved
So, I got it working again. The problem was indeed in the persist folder, it was missing a file named WCNSS_qcom_wlan_factory_nv.bin. So I managed to extract it from the persist.img and moved it to persist folder again. After that I edited the bin file and inserted my MAC address. Finally I have flashed my phone to stock ROM again and it worked just fine.
Here's the file:

fixed
Thank you so much this fixed my problem as well

Ok. Let's try but first let me e sure how to do it.
1. Edit persist.img with the .bin file inside.
2. Installl stock rom on my phone.
3. Flash persist.img in fastboot mode.
It's that correct?

First of all check if your persist folder is missing the bin file I have mentioned. If it is, You have to extract that file from persist.img or You can just download the one I uploaded.Then you must edit it and insert your mac address and after that you just have move it to the persist folder using a root explorer.
I could not flash persist.img, bootloader was always returning an access denied message, so i figured a way to explore the persist.img file using LinuxReader and extracted the WCNSS_qcom_wlan_factory_nv.bin from it.
So basically i ''flashed'' persist manually. Copy, edit, paste.

Thanks
Fixed
I have 2 days searching the solution and try with so many files.
Thanks

Please, could someone explain me exactly (for n00b like me) how to solve this problem?

Solved

I formated /persit folder also, tried install stock rom, but no success with wifi
The problem is: i have no persist folder inside root and when i try to create it, the folder was gone after reboot.

Wi fi problem
Hi guys,
i've a Moto G 16 Gb purchased on Amazon.De, so german phone. I live in italy and when i connect to wi fi no problem. When i go in switzerland and i try to connect to another wi fi net (my girlfriend's line) provided by Swisscom, it doesn't work: well, i insert passoword, but it cant connect ... i called Swisscom, they tried to reset router and so on , but still persist this problem. The person (swiss) that sells me the phone (i bought it as used) said that he has the swiss provider Cablecom and it didn't have any problem. I'm fully stock with 4.4.2 . Anyone has any idea? thank you
ps: with my galaxy s3 i have no problem both in italy and in switzerland

Can anyone help in explaining the above?
....to a relative newbie? I've downgraded from 4.4.2 down to 4.3 and now my wi-fi is not working anymore, the MAC address is lost.
I'd really, really appreciate any help with regards to the procedure in going about fixing the 'Persist Folder' .
Thank you for reading.

Please make any method to solve Persist folder
Downgrade from 4.4.2 to 4.3 XT1034 UMTS...

I'm sorry, but can you please elaborate? I'm have this wifi issue and it's really annoying.
You say to extract the file from persist.img, but where exactly do I find that? The file you uploaded is not persist.img.
How would I edit and insert my mac address?
Where is this persist folder? I can't find it anywhere.
If you could respond that'd be great.

The file which he uploaded in post 3 was extracted out of the persist image.

You'll find persist folder at /persist.
You need filemanger with root permission, the you can see this folder.
So copy WCNSS_qcom_wlan_factory_nv.bin to your SD card. Use your filemanger to copy this file to /persist.
Activate wi-fi, the you'll find your mac adress under Settings > About Phone > Status > Wi-fi MAC Adress
Open WCNSS_qcom_wlan_factory_nv.bin on your phone with a text editor and type your mac adress inside that file and save it.
I have not tried it because i did not have this issue. But this is the way how i understood it.

simply copied the file in /persist, set permissions and rebooted
No MAC adress to enter
Works fine now

Thanks, very much!
You resolved me
Only its the put the WCNSS in the /persist folder and OK.
(You need to have the firmware with /persist).

[Q] How to extract build.prop from system.img

I have the stock rom for the Galaxy S6 Cricket variant... I am having trouble in getting the build.prop from the system.img. I have tired many methods from other threads but none seem to work. Any suggestions or working ways to extract the build.prop from the system.img or any way to open up the .img file.
I am doing this to post the rom in the ROM WIP section for the root.

Try the tools in this thread . I used them last week to extract a build prop.
Just load up the system.IMG and drag the file from the system folder to your desktop.

I got your PM. Sorry for the late reply. I'm posting here in case someone else needs the info.
Download Ext2explore.
Extract to your PC.
Run as administrator.
In app: go to file - open image - (find your system image) and open
It will display your image in tree and folder view
Use either one (depending on your preference) (but your build.prop will be in the first view as its in the root of the system).
Right click the file/s you want to extract
Select save
Save your file.......profit
Hope this helps
