Samsung Galaxy S7 (G930F) - EFS recovery - Samsung Galaxy S7 Questions and Answers

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

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

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.

Samsung On5 G550T1 MetroPCS REV0.4 stock OS anyone?

Hi All,
The short of a long story is that I just changed carriers and found out way late that I couldn't bring my Sprint phone to MetroPCS. So now I'm using the budget PCS On5 that came with the deal when we signed up.
I successfully loaded TRWP and then rooted however, I didn't know about FRP until it smacked me in the face. The root went fine but later SU prompted me to update the binary and when it did, it tripped factory reset protection and soft bricked my phone.
I want to reinstall stock OS on this phone but it appears that I have a software version that I haven't been able to find on the web yet. I found the stock rom for the MetroPCS On5 easily enough but it's Revision 0.0 and the box I have for the phone says REV0.4.
When I try to Odin Flash the REV0.0 version, I get SW REV CHECK FAIL DEVICE 2, BINARY 1 fail. So I guess I had the latest software on my phone and the phone thinks I'm trying to roll back using the 0.0 revsion.
My question is this, does anyone here have the stock rom for G550T1 REV0.4? Help!
If nobody does, maybe I can still fix this phone. I have a TRWP backup from the sister phone (same model same revision 0.4) that I'm using right now but I can't get back into TRWP on the soft bricked phone to recover that way to use the backup file.
Next I thought I might take the backup files and turn it into a rom and just flash that. However, with the tutorials I followed I kept running into problems. When I went to unpack the files per the tutorial, my rar software said that the file was corrupt. Maybe it is. but maybe not. It was my first time attempting to make a rom. If I can't find the software I need, could any of you Android geniuses help me get this backup into a flashable format?
I have to admit I'm daunted by the FRS in 5.0 and above. Is it defeatable? How do you root newer Android versions?
Thanks!
I did the same thing to my phone. did you get yours fixed?> if so could you provide me with the rom?
I haven't found the fix yet. Hopefully somebody will come through with a helping hand!
I finally got it figured out! So here is what i did and hopefully it will work for you.
1. I Odin flashed a good BL from the ROM REV0.0 floating around on the net. So at least I could now get into download mode.
2. Then I used Kies3 > Tools > Firmware Upgrade and Initialisation. It will ask you for your model number and then when you click ok it will ask you for a SN.
3. The trick is that Samsung doesn't put the SN that you need on the phone or the box. (personally, I couldn't find it on the phone either once I got it up and running) so go here: https://forum.xda-developers.com/android/general/root-samsung-galaxy-on5-t3435457/page46 and get a SN from post #454 and use that. (don't forget to say thanks)
4. Click Ok. Let it work, and max and relax.
Mine took about 10 minutes. Hopefully this will work for you too! Thanks XDA!
Help!
What is BL from the ROM REV0.0? I need your help, I have the MetroPCS On5 and I installed Reborn ON5 I want to go back to the MetroPCS ROM because the camera and the audio do not work and I tried to install the original ROM through Odin but it does not work I get an error. What I can do? I would like to use this method but I do not have very clear files needed.
You could help me bro, I'll thank you

ROOT & Stock ROM for SM-J727S Galaxy J7 May 2017

Hi guys,
I was hoping someone could help me out. I have rooted before (long time ago) but I can't seem to find a lot of information on this specific phone (SM-J727S). I have been searching online (and across many dodgy looking websites, thanks No Script!) and this is about all that I have found:
The Galaxy J7 is also known as the Galaxy Wide 2 in South Korea
http://pdadb.net/index.php?m=device&id=11601&c=samsung_sm-j727s_galaxy_wide_2
It was released on May 2017, runs Android 7.0 (Nougat) and uses the Exynos chipset
TWRP has a release for the J700 series but I'm not sure if it would work on the J727S
https://twrp.me/devices/samsunggalaxyj7exynos.html
The source code for the system has been released, but I couldn't find a stock ROM (which made me reluctant to try TWRP)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=j727s
This is the closest I got to a Stock ROM but I don't trust the site, is this site trustworthy? (again, I came across too many dodgy sites to just download anything)
https://stockromupdate.com/2017/07/26/stock-rom-sm-j727s-samsung-galaxy-wide-2/
The KingRoot method currently will not work and is asking me to wait for an update (phone is probably too new to root?)
The closest thing I can find on this forum are these posts (but none reference the J727S model)
https://forum.xda-developers.com/galaxy-j7/development/root-sm-j727p-galaxy-j7-perx-td-lte-t3611202
https://forum.xda-developers.com/galaxy-j7/help/root-sm-j727p-galaxy-j7-perx-galaxy-j7-t3598117
So, I'm hoping someone could point me in the right direction. Thanks in advance
I'd thought I'd mention that the bootloader is unlockable in this phone. I had read elsewhere that other people cannot access the 'OEM Unlock' option on their version of the J7. It isn't the case with this phone
https://forum.xda-developers.com/galaxy-j7/help/galaxy-j7-pop-galaxy-halo-t3647805/page2
I also got a message from Google talking about my accounts being accessed by a 'J7 Pop'. I guess the Galaxy Wide 2 is also known as the J7 Pop?
So, I'm still on the track of rooting this device. I'm just gonna update any relevant stuff here.
The closest TWRP that I can find is for the 2016 version of this phone, it has the same Exynos chipset.
I'm thinking of trying this, but are there any problems with flashing the wrong version of TWRP? (Will I brick the phone? Or will it just error-out on recovery and boot normally?)
https://twrp.me/devices/samsunggalaxyj72016exynos.html
I also found (what I believe to be) the Stock ROM for this type of phone, you have to sign up to the site in order to download it. It is specific to SK Telecom (Korean telecommunications provider)
https://www.sammobile.com/firmwares/samsung-galaxy/SM-J727S/SKC/download/J727SKSU1AQD6/172065/
If someone can advise about going forward with the similar TWRP version I'd appreciate it. Cheers!
EDIT: Kinda answered my own question, from the TWRP download page https://dl.twrp.me/j7xelte/
Downloading an image for a different device, no matter how similar, usually does not work.

Any way to request an TWRP version?
I am Korean, and it's very hard It's angry me............................
XDDDD I'm from South Korea too and the J727S is customized with the Knox Enrollment Service that blocks the wifi and cellular data AND apk installization. (trying to uninstall it )
I found this: https://www.androidinfotech.com/2018/02/root-samsung-galaxy-wide-2-sm-j727s-nougat.html
anyone habe twrp for this model ????
Hi.. I've this model also.. tried to downgrade..but it can't..always failed
My friend was installing the twrp to root a J7 metal.
Now the cell phone does not restart, and I do not know what the **** it did KKkkkkkkkkkk
It wants to remove the twrp without formatting the device.
If installing the original rom by Odin using home_csc does it return to normal without formatting?
Restore

Mt8163 Captiva Pad 10 2-in-1 won’t show anything after flashing rom

Hello guys,
I’ve got a problem. I’ve bought a Tablet with android of a company called „CAPTIVA“
Now I’ve tried to flash another Firmware of a device called TitanX2. So my problem is that the tablet works but only the sound of screenshots and the lockscreen.
So now my question is:
Has anybody here this Tablet to make a backup of this device or does anybody know where to download the original firmware?
BTW I formatted the device completely and there is no chance I think to restore it without any matching scatter and system files.
Thank you in advance
I’ll post the link to the specs of the device later
Bye

Huawei Mate 9 - A Combination Of Issues

Hello dev's !
So I am surfing alot of threads here lately and I finally have this chance to post my problem & hopefully get some help regarding my problem.
Device Info - MHA-L29C185... (Middle East Version - Dual SIM). Don't remember which stock rom I was on but it was oreo so maybe somewhere close to 374 or earlier version.
Problem :
Firstly, I rooted following one of the threads from here and it was successful. However, I messed up when I downloaded an app which modifies framework or something and it bricked me and pushed me out.
But luckily I had some help and I used Chimera Tool to flash the International Version which brought my phone back to life but a lot of features like WiFi, Fingerprint Scanner didn't work.
So I decided to re-flash my firmware ie; C185B374 (Middle East Version) hoping it would solve the problem. It did solve the Fingerprint and WiFi problem but gave new problems like Gallery App (System APP) not working and Bluetooth not working.
:crying:
Note : I tried downloading firmware files from Firmware Finder & and flashing all 3 files using twrp and it fails as there is some mess in the Partition which isn't resolving. :crying:
I tried flashing using firmware finder app in the phone. It downloads the firmware and everything but doesn't flash. :crying:
Now, when I try to rebrand also which seemed a possible solution, I get stuck on the step where oeminfo files has to be replaced from the twrp backups. The script just doesn't respond.
Well, I am still living with the phone but alot of features don't work.
Help Required is :
1. Need solution to get stock firmware working properly as I am currently running my regions version but features don't work.
2. Lock back bootloader if possible. ( ADB Method & Team MT Multi Tool have been tried with no success)
3. Possibly get everything back to orignal. That's all I want !
Can anybody provide a possible solution to this ?
Nobody ?
My thought:
Download the firmware images you want to install.
Follow the instructions for using HuRupdater (search, I don't have the link handy for it); basically: put hurupdater and your update zips in the same folder on microsd, flash hurupdater with TWRP.
For relocking, you should be able to use "fastboot oem relock", though the phone will show that status. If that's fine, go for it.
