How can I solve a IME problem without EFS backup
I've been reading some tutorials on how to create / modify IMEI of the phone.
I did some things without success:
- Install the original ROM cell.
- Install Other ROMs.
What I can not do alone:
- Using EFS Profisional to change the IMEI.
I've seen the IMEI concert here in Brazil is R $ 500,00.
[Please, I need help because i do not have the backup of EFS.]

Hello friends, I have problems with my NotePro 12.2 sm-P905, I live in Argentina and buy tablet abroad (Chile) after a while using it with wifi, I decided to put a chip for use with 3G, here is my surprise I attached pictures of my problem, my imei is / 01, that means? down several firmware and I've done clean installs all wipe and nothing ... imei not exist, that I can do ??:crying::crying:
No how to properly upload the images so leave some links so you can see that I speak.
I hope your help, greetings. !!
(I can not place photos)
When I place * # 06 # on the phone to the tablet, I get
*
IMEI
**** / 01
That's it ... and I have no files in the folder EFS necessary to restore IMEI
Hello all.
I've installed the 7.1.1 ROM on my Jaiyu S3 phone, as described here:
https://forum.xda-developers.com/jiayu-s3/development/rom-unofficial-aosp-n-jiayu-s3-t3451923
(I also root it via SuperSU)
The ROM works great (thanks team M.A.D!), but after flashing it my IMEI is now empty (and as a result I can only make emergency calls).
I've installed MTK Engineering Mode (hoping to edit the IMEI through it), but it says "Cannot find EngineerMode App" when I try to use it (I understand that this is, perhaps, due to the ROM not including support for engineering mode yet).
I've tried using Chamelephon (https://play.google.com/store/apps/details?id=com.cryptotel.chamelephon), but it also doesn't work (it resets the phone after setting the IMEI, and when it reboots the IMEI is empty again).
I thought about editing the IMEI via one of many available Xposed extensions, but Xposed itself isn't available for 7.1.1 yet (see here - http://www.theandroidsoul.com/xposed-android-nougat-7-0).
So... I am at a bit of dead end at the moment. Can someone help?
Thanks!
Hi,
I bought an IMEI changed Samsung Galaxy Note 9. Its rooted using Magisk, I m not a familiar with android ROM installations.
I want to upgrade android version from currently running 9 to android 10. But I dont want to loose the Changed IMEI.
What will happen if I flash official android 10 ROM onto my device, will the IMEI be changed to the factory one?
Thanks
Backup /EFS partition before changing ROM.
FYI:
EFS stands for Encrypted File System. Imagine the EFS as a big folder containing all of the important stuff that makes the "phone" part of your phone (i.e. what lets you communicate from one person with a phone to another) tick. It contains your IMEI, lots of files revolving around your SIM card and Wifi/Bluetooth (this includes your MAC address for all the radios of your phone), and lots of other things that should never ever under any circumstance be deleted or touched. It's sensitive, it's devastatingly important, and it's a huge pain. If you lose your EFS folder, you lose pretty much any chance of your phone being able to use data, Wifi, Bluetooth, and ( probaby) your phone will just not want to respond and reboot quite a lot.
Hi all,
Just wanted to give a background story as to why I formatted the Flash by accident on my device. I received the phone not too long ago and was excited to venture into the possibilities of testing and trying out different images. Unfortunately without backing up the device I kind of jump the gun and formatted the drive after I ran into some issues thinking I could restore it with the Stock ROM files. To my horror I found out that not all ROMs were included when reimaging the Stock Roms.
So, here I am. The device is working ok, but these are the issues I'm facing below:
- Partially lost of cellular signals - (Flashing "Modem.bin could resolve this, but don't know where to flash it or what folder structure)
- Wifi working inconsistently - (Stock Roms, does include a "Modem_bin" folder with the files, but again don't know where to flash it)
- Don't have all the calibrations files (Maybe I do, but don't have the correct partition or where it would be placed)
- The Databases were also included, but again don't know where to flash it
- Lost IMEI/BaseBand - (Fixed by flashing IMEI numbers through SN Writer Tool)
- Lost Google Device certification - (Fixed by flashing Attestation files with SN writer tool)
Few things I need help with:
- Does anyone have the full structure of their Doogee V20 phone that does not mind pointing me in the right direction of where to flash the Modem.bin files to?
- Also, if IMEI and SN is corrected, does it means now that the NvRam and NvData info is all there or partially there?
Thanks in advance and hope my insights or issues helps other to avoid my mistakes.
I have attached the scatter files and stock roms if you have any way of extracting what I need from them I would highly appreciated it.

Stock rom : Here

Probably EFS partition ( it contains product code, IMEI, BT/WiFi mac address, RIL calibration files, DRM info and some other data like language, timezone set by your provider ) got wiped when flashing new Android version.
If you haven't taken a backup of this partition then you've lost, AFAIK.
