[Completed] Invalid IMEI problem on Symphony Xplorer W69Q after installing Custom ROM. Help plz. - XDA Assist

Hello,
I have ran into a problem. I am using Symphony Xplorer W69Q and I was looking for a custom ROM. I was liking mostly MIUI. So I have contacted them and asked if there has any Custom ROM for my device. They told me that there has not any ROM for my device. So I have searched on google for any other custom rom and get one of MIUI 7-
So I have decided to make a try.
One I have collected Philz touch recovery and flashed the ROM, I have lost my IMEI. I didn't take a backup of my current ROM too. Finally I have no way to get SIM card working as they are no longer being detected.
I think I made the mistake by wiping the cache and also dalvik cache as per their silly instruction. I have installed the ROM successfully and there have not any other bug except the SIM card/IMEI error.
When I press *#06#, I get-
IMEI1- Invalid
IMEI2- Invalid.
Then I flashed the following Stock ROM using SP Flash Tool
(Symphony_W69Q_1_FL_V03.0_V1.0)
But still I can't get RID of the Invalid IMEI problem.
I also tried to use the SN writer tool. But I couldn't find the database file listed here
androidmtk[dot]com/use-sn-write-tool
(I couldn't get any file of MDI_DB and AP_DB in my stock ROM)
Also tried this tutorial
on Youtube-
Android phone invalid imei repair
by Azeem Md
But it not also worked for me. I couldn't find the database file for my Phone.
So I am still stacked on Invalid IMEI problem. I also tried Chamelephon.apk and Engineering mode in MIUI 7. But there the CDC Information can't be selected because it is grey there.
So is my phone dead now????.
Please anyone help me by providing me a working solution with necessary file download link.

[Completed] Unbrick LG G3 Beat D723

Quite recently i recovered my Beat when i managed to soft brick it and it just booted into fastboot mode or whatever you call it (im a newbie).after days of searching the web i managed to find something called LG Flash Tool from which you can flash a .kdz file which i think is a firmware file .You can find how to use the LG Flash Tool from here Mod Edit .You need to download the firmware file and i downloaded it from here Mod Edit (im guessing it works on other models as well such as the D722 or the D724).
Once downloaded you need to open the LG Flash Tool and select the firmware file you downloaded and select either of the two flash options (normal being for the one with your data being recovered and Csu the one with your device being wiped ) i did the csu as i had already messed my device up .I hope you find help from this thread and manage to recover your beat and best of luck to you all.
Greeting,
XDA Assist is not the correct section to post this in.
Please re-post in the device specific forum.

Help: FreeTel Samurai Kiwami FTU152D

Greetings for all xda members,
I need your generous support regarding my Freetel Kiwami FTU152D.
It was working well on android 5.1 but i made a blunder by flashing a custom android 6.0 rom from needrom.com made for FTJ152D. I supposed that the FTU152D is having same hardware as FTJ152D , and its just and american version of the Japanese model.
But unfortunately things went wrong and i phine lost the IMEI after flashing.
Steps done to restore/Write IMEI:
1: Engineering mode:
CDS information is not available in engineering mode, tired to install CDS but failed.
2:Maui Meta Mode:
Phone reboots and doesnt enter inter meta mode.
3: SN Writing tool:
Phone simply reboots and fails to write the IMEI.
4:Rooting
almost all android and PC rooting apps(Kingo,King,Farmaroot, Root Genious etc.) failed to root the device.
please guide me how to get the IMEI working on android 6 or how can i got back to stock android 5 rom, haven't find and stock rom yet.
looking forward to experts opinion.
thanks.

Samsung Galaxy S7 (G930F) - EFS recovery

Hello XDA-Members,
I hope to get help here with following issue:
G930F had G930FXXS7ETA8 (Android 8) installed.
I cloned another G930F using TWRP.
By accident I cloned EFS too !!! OMG!
Now SIM-Card is not recognized anymore.
Anything else is fine.
I don't have a backup of EFS for the target device.
But I do have screenshots of Settings>Software Info !
So I know the IME the device had before the accident.
Years before I managed to recover a EFS with a combination ROM.
I tried to flash but the bootloader isn't compatible (need version 7, combination ROM has version 5).
All other tutorials I found did not help me.
Does anybody know how to solve this?
Really hope so!
Kind Regards
Andreas
Hi Andreas,
try this if you haven't already? It helped me getting back my IMEI and working WLAN. Sadly my bluetooth connection is still not usable as i wrote here.

Hello again,
hainguyenthao fixed the issue for some money.​Communication with this XDA senior member was not the best and it took much time for him and me.
In the end he left me alone with a not-ready-to-use phone.
BUT after some unsuccessful attempts to flash the official ROM without issues,
I cloned an identical device in UNLOCKED state with TWRP and everything is fine now.
If you ever want to clone with TWRP ensure the following:
- phones MUST have identical hardware
- remove any PIN / pattern / password from source phone before backup (= UNLOCKED)
- double-check to NOT overwrite the EFS-partion at destination phone !!!
- Please note, that TWRP does NOT backup your internal SDCARD !
(/storage/emulated/0)
For sure it's always a good idea to have a full backup of your device !
Beside TWRP I have screenshots from all IME and software relevant settings.
Be happy!
Andreas
