do you have any backup of previous roms or atlest your EFS ??
If you have flashed the rom from Philz or CWM recovery then there are high chances that the developer have used the option of "Backing up EFS" and it might be on your sd card..
Please share what have you done so far with your tab.. if you got no backup of EFS then forget about calling functions of your tab .. All i can help without the EFS backup is in restoring your tab back to its normal state..
go to sammobile.com download your ROM from there :
1) Go to sammobile
2) Register and sign in
3) Go to firmware section
4) download the P3100 rom of your location ..
5) Flash it with odin with "Phone EFS clear " option UNTICKED
You might have ticked that option and your EFS got cleared .
Efs holds the imp data like IMEI numbers .. which is illegal to fiddle with in any country..

Do this only if you are little expireinced in rooting and stuffs ..
and i hope next time onwards you will be carefull to backup your EFS

well first forget about the efs imei and calling functions.. just restore your mobile to normal state .. like usable without simcard...
I told you to download from sammobile .. and flash that tar.md5 file from odin..
EDIT.. i realise that you already have the device in a working state lol ..
Just back up the current EFS "the currupted one" and folow the instructions on a the link i gave you at the bottom of my previous post..

it might be just a widget .. try removing it .. if it doesnt then i think you should just try to reprogram your EFS rather than trying to remove that yellow thing..
Just follow the links i gave you.. study what efs it .. go to the last link i gave , and try doing the things that it says to create your EFS..
Note: the guide is generic for all samsung galaxy devices .. so you might have to google up a bit to keep up with the guide..

If you're rooted download terminal emulator and Google how to exit factory mode on Samsung

[Q] Q How to backup my stock rom

Hello guyz, the title says all; bytheway I meant how to back up my stock rom of my new GFit XWQ3 coz I cant find it...And also without using the rom manager coz I know it briks the phone. At the end how to restore it after a try of a custom rom
TY to reply
My version is:
PDA S5670XWKQA
PHONE S5670XWKQ3
CSC S5670ITVKQ3
ANDROID 2.3.4
let me guess
you're italian just like me and maybe an S-lunga customer
i've rooted my phone so i don't know if i could help you providing a good rom backup
if it's possible i'll be glad to do it
a shot of my fit version just to be sure
h*tp://i.imgur.com/0mPnP.png
"let me guess
you're italian just like me and maybe an S-lunga customer "
lol yeah exactely
we have same versions.
BTW it is possible restore a backup using this http://forum.xda-developers.com/showthread.php?t=1339640 , in restore mode and saving that backup to SD?
install cwm and backup using it.
and are you sure that if I backup via CMW I will be able to restore my stock rom from this backup after I will have tried any other custom rom?
I have already CMW 4 on my system, after a recovery power on, I have selected backup and it putted the backup on sd folder named CMW/backup...I know I can restore it with the restore command, but I am not sure if it will work, or if will BRICK my phone
yes, i myself have used it.
great ty..and I can see on my sd these files :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is this all fine?
There is a way to know if the backup is not corrupted?
image doesnt work...
it must have completed successfully, or it would have shown an error.
back the backup to a safe location on your pc.
backup was fully done, and I ave already saved on my pc...so now may you tell me a couple of very good custom rom without bugs?
last thing...on my backup stock I have my all originals "PDA S5670XWKQA PHONE S5670XWKQ3 CSC S5670ITVKQ3 ANDROID 2.3.4" and I can restore all with CWM ? right? TY for ur patience
IMO,
RazoDroid, Chocobread are the best.
Creed's ROM is kinda good too.
---------- Post added at 12:07 AM ---------- Previous post was at 12:06 AM ----------
just head over to the development section and experiment all you want...
I will try
did it work?
can you tell me what precisely you have done?
I asm also an esselunga customer, italian is easier for me )
for me it doesnt work
what doesnt work?
I cant return to my stock after the backup..I am stuck on custom now.
After recovery via cmw my phone restarts and loops like a hola hop

After a custom rom, install Titanium Backup, open it, press the left button, select Batch, select All restore and follow instructions.
Previously, when doing a backup, select Backup All apps + data.

mmm it seems quite strange...why other people use cmw , wipe cache , dalvik etc? your way seems a lot easy

[GUIDE] Rooting ALCATEL OT-918 (v2.3.6)

Hello everybody,
This is just a small guide I made for rooting ALCATEL OT-918 (Maybe also 918D or M) devices on which SuperOneClick fails. Most of the files are not by me so all credit goes to the original author...
Tutorial:
01) Unzip usb_driver.zip and install the drivers. (phone shall not be off an plugged in, thx dbask)
02) Copy the file Superuser-3.0.7-efghi-signed.zip to the root of your SD card.
03) Make sure your battery is fully charged and turn off your phone.
04) Head to the directory SP_Flash_Tool_v2.1134.00 and start FlashTool.exe.
05) Make sure the menu Options->USB Mode is checked.
06) Use attached scatter file creator to make scatter. (or use Android_2.3.6_MT6573_Android_scatter_918.txt)
Warnings/Errors like this can be safely ignored:
Code:
[Warning Hint] Get BMT block count fail, default BMT block count is used!
Code:
[Hint] Bootloader files are lost when automatically loading by scatter file.
Code:
Please make sure you want to go through anyway.
Code:
DSP_BL is unchecked, which may result in a boot failure
07) Check the entry with name "RECOVERY" and double click it.
08) Select the recovery.img file and again make sure ONLY one entry is checked.
09) Click the Download button and plugin your phone with the USB cable.
* Wait some time (untill the recovery file is loaded to your phone) *
10) Unplug your phone and press the volume up and power button at once
11) Select "Flash Zip from SDCard" and choose the Superuser-3.0.7-efghi-signed.zip
12) Confirm the update and reboot your phone. Everything should be done, phone is rooted!
Actual tutorial made by others. I only try to make it a bit more clear.

ALCATEL Scatter Retriever v0.1
Just to make this thread a little development related: I coded a tool that should be able to automatically create scatter files for your (ALCATEL) device. It is only tested on my own device but it should work for other (ALCATEL) devices too (Sources can be posted if needed).
Screenshot:
Last words
The tools and files used to make this tutorial are not created by me. The FlashTool is made by MediaTek (the company that makes the ALCATEL devices), the recovery.img is made by somebody at 592zn, the USB Drivers are made by MediaTek/Alcatel (unsure).
I wish you all a very plesant day,

download the One Touch Upgrade software from here: http://www.alcatelonetouch.com/ph/products/andorid_smartphones/ot-918.html to reinstall your OS
to root, use this:
http://forum.xda-developers.com/showpost.php?p=27178532&postcount=16
Device is upto date and exits
I did that and it says there is no other later version than the one already install on your device and it exits.
Is there anything else I can do?
Thanks
@kippsoft: Sorry, but I cannot give my data and cache... it contains private stuff such as contacts, emails, password and all stuff like that... nothing more to do I guess
@ mr.expdia: I am very very grateful
I am very gratefull for all that you have one to me.Your time spend and assistance is highly appreciated.
Thanks alot.
But said those images were for Alcatel OT-918?Please confirm that?
I thought those were images before you used your phone...it is okay.
And do you have any working custom rom for 2.3.6? Most of the available are for 2.3.5.
Though my problem is not solved...I have learn alot and that is exactly what I wanted when I joined xda.
Thanks to all.:good:
They are captured while rooting my phone, so yes. And I do not have a custom rom, I think you need to wait for one to be created.
Greetings

Same problem was with me too. But my phone was in warranty so I got it to service center and now it will be replaced with a new one. Hey XDA Guys is there anyway we can prevent this thing? Even I did wipe all data and the phone just booted till screen where Android image comes and then restart.

{OEM}[ROM][TUTORIAL] Micromax Funbook Original Livesuit Image LEAKED !!

UPDATE : just a quicknote, i just found out that this img file makes the /system partition of 503Mb instead of 251Mb as other img for MOMO9 or older tablets, So in order to have a bigger partition, one can flash this, then install anyother rom, for instance, cyanogenmod 9/10 full version instead of lite. Good luck flashing guys
___________________________________________________________________________________________________
Hey everyone,
Presenting a leaked version of ORIGINAL MICROMAX FUNBOOK livesuit image for P300 Model (from MM SC ). If you want to revert back to original rom, worry not, no need to copy that backup file & restore using CWM recovery. Some of us were even having trouble to revert back to original with cwm backups ( failed to restore /system error!). so here is it the answer to getting back to the factory state of our tablet.
Procedure:-
JUST DOWNLOAD THE 7z FILE, EXTRACT AND FLASH THE MMX_Funbook_P300.img IN THE SAME FASHION AS OTHER LIVE SUIT IMAGES. FOR TUTORIAL ON LIVESUIT & DOWNLOADING LIVESUIT REFER :-MOMO9 LIVESUIThttp://tabletrepublic.com/forum/ivi...-ployer-momo9-firmware-rom-releases-1610.html
Congratulations on getting 100% original software installed on your rom. Go & claim your warranty if you want ( tho MM suck at it to the core )
POST INSTALL NOTES
Once you have flashed this image, you will find yourself with following specifications :-
Baseband 1.2
Build Number 97F1-D1-H2-MMX.20120914
If at this point you want to get another rom installed or you have to get root, install superuser & get clockworkmod recovery the old methods does not hold any good. You have to follow this procedure to get root & install cmw recovery. THIS METHOD IS SAME AS FOR ALL ROMS WITH BASEBAND 1.2

}
Getting the power of ROOT
Now the easiest way to get root is to use UnlockRoot software which works as a charm with our funbook device. Just connect usb cable, enable debugging & press unlock on the software. Then after the tab is restarted (by the software) you get root & superuser installed.
Getting CMW recovery on the tab
Once rooted we need to install ES File Explorer on our tab. Once installed, Go to settings, in root options tick the all boxes
Make sure superuser prompts, hence verifying successful installation of superuser. If not GET SUPERUSER UP & RUNNING FIRST.
Then navigate to the root folder by pressing back key. Stop where it says press back again to exit. ( in address bar the address will be / )
Next there will be a folder named Dev(/). long press on this folder & scroll down to set properties. Then click change, check all the boxes are ticked
Repeat the above steps with data folder (/), block folder (/dev/block), nandg file (/dev/block/nandg)
Finally all the complex part is behind us, to ultimately install the CMW recovery now, just use your old cmw recovery script for ICS, run it & done, it will be installed. Reboot & check pressing the volume down key + menu key & power key.
Njoy guys .... have fun & oh .. hit thanks too

oh really sorry for such late reply ... but have you tried installing another copy (fresh copy) of livesuit from the internet ? have you properly connected the tablet by pressing the vol - & options button simultaneously & hitting the power key 10 times ???
i have tried almost all those firmwares out there for funbook or momo9 ... i have faced this issue many times but you might not be pressing the button configuration accurately ... rest assured your tab is fine & 6k is not a waste as u might think !!! GOOD LUCK & report back if you still face problems, i'll help you step by step if needed !

[GUIDE]Restoring your lost IMEI in MTK phone

A common problem many face in their phone is loss of IMEI no. This is results in no network detection by your phone. U can come to know you have lost your IMEI by checking Settings->About phone->Phone information. There under IMEI section you won't be finding your mobile IMEI numbers displayed.
Don't worry you can restore your IMEI's. Just follow my guide and you will be able to restore your IMEI. We will split the tutorial into two parts.
BACKING IMEI :
First step before performing all these things is that your phone should be rooted.
When your phone is in normal state with everything functioning install Root explorer and navigate to the below location >ROOT>DATA>NVRAM>MD>NVRAM>NVD_IMEI>MP0B_001
Now copy this MP0b_001 file to your SD card or PC whichever place you feel the file we be safer.
Now download MTK Droid tools . Now extract the zip file and open the MTK droid tools exe file.
Now in your phone turn on USB Debugging by going to Settings->About phone-> Developer options and there turn on USB debugging. Now connect your phone and MTK droid tools should be able to detect your phone. U should see a window like this appearing after your phone has been detected.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now press the ROOT button present in lower right corner. When it asks Supersu grant in your mobile click allow. After MTK droid gets access u should see a green colour box appearing in the lower left corner which means u have correctly granted access to MTK droid.
Now click on the IMEI/Nvram tab. A window should open and click backup NVRAM and MTK droid tools would take a backup of NVram in its folder.
RESTORING IMEI :
Now when you lose IMEI first try this method. Now take the MPDB_001 file which you took backup at the first step and navigate through Root explorer to this location ->ROOT->DATA->NVRAM->MD->NVRAM->NVD_IMEI. Now paste that file and replace the one present there. Now set the permissions for that file as RWER-ER-E. Now reboot your phone and you should be able to get your IMEI back.
If you still haven't got IMEI open MTK droid tools and connect your phone and press ROOT again and give MTK droid tools root access. Now click on IMEI/Nvram tab and select Restore option and restore the NVram backup which you took earlier. Now reboot your phone and you should be able to get your IMEI.
Extreme method :
After performing all the above if you haven't still got IMEI. Now switch off your phone and open SP Tools and connect your phone. Now click on format and format your whole phone. ( This wipes whole of the phone including NVram region ).
Now flash stock ROM through SP Tools and after it completes start up your phone. ( Don't be surprised. Your IMEI will still be in lost state only ). Now root your phone.
After successful rooting now connect your phone to MTK Droid tools and again press ROOT button and grant root access to MTK Droid tools. Now click on IMEI/NVram tab.
Now as you see in the image above you can see two boxes IMEI1 and IMEI 2. Now enter your device IMEI numbers manually in those two boxes.( You can get your IMEI no's from your phone box ). Now click replace IMEI. Now reboot your phone and you should be definitely able to get your IMEI restored.
Should you have any queries feel free to contact me and I will be there to help.
Will this work for SIM ME lock? Which popups every time I reboot my phone? It's annoying, it happened after I flashed CM11 ROM. Can you make it go forever?

UNKNOWN IMEI after cleaning kernel on n8000, Got pretty messed up

Hello guys,
I got messed up with my tablet
The IMEI is unknown now
Here's the chronology
1. I flashed Gnabo rom v7
2. Then the network seemed unstable, in which it got disappeared and reappeared randomly.
3. I thought I should flash boeffla kernel, then I flashed it
4. Network seemed stabilized
5. I left it over night, and in the morning the tablet lost its signal, in which it show "no SIM card inserted".
6. I restarted over and over, change the SIM card, nothing works
7. I remembered I haven't clean the kernel script before I flash the boeffla, so I think that was the cause.. Then I decided to clean the script via CWM With "sybr cleaning script" which I got from here on xda
8. Reboot the phone and voilaa! The IMEI Is unknown
9. No more "no SIM card inserted", just a blank signal on signal bar
10. I tried a way to restore the imei here on xda on thread "9 steps to repair imej", in which the methods is to backup efs folder manually, and then so on an on.
Now my tablet shows random transparent window in which shows some sort of tablet information
Here's the picture

If you have a backup with efs partition init you simply recover this. (Better all)
If not I can tell you that I needed 3 weeks to recover mine. And now I have a fake IMEI.
But it works.

I haven't backed it up yet
But I read here in the forum that the efs folder is untouched, so I assume it still intact?
Could you tell me how to recover yours?

I cant tell you what I've done the whole 3 weeks. But finally succseded with ChimeraTool.
same problem here no IME and no EFS Folder note at factory test screen
after flashing the [4.4.2] Gnabo Rom V7 [AIR COMMAND - NOTE 2014 APPS ] ROM with clean flash and it worked great for few days the note awake one day in a loop restart...I wipe all again and here started the drama... I lost the EFS folder and I am without a back up for it....I tried to downgrade the bootloader to flash a stock icescream sandwich sam rom maybe that restore the original efs but what I got a factory test screen with no EFS or IME please help and for anyone read this please consider that the above ROM could have a bug .... I am not the only one who got that problem pls backup your EFS folder and consider the risk for bricking your note.
SAM service answer/solution for repair it was to change the board (80% of the device price) = go buy a used one or a brand new from a cheap country....
appreciate any help
please Arnomaf tell us we need and appreciate your help
did you bought a license to repair IME ?
did you be able to restore your original IME with this tool ?
I have to wait to pass the 3 days trail or buy a license from day one?
it worth it..i mean it really were the only step to restore the ime and efs folder through this tool?
