Development [10.04.22] F926B I Dr.Ketan Magisk ROM I OneUI 4.1

Search This thread
Hi all. The worst has happened to me. Lost EFS and my computer died with the backup. I got a new one, unrooted back to stock but IMEI is 0 and no EFS. I am really in a bind. Can someone send me a copy of their EFS backup? I my fold is functional again but EFS and IMEI is gone. Only had my fold a few months

Sounds like Murphy's law at its best. Don't say that Dr. Ketan's ROM caused this. ;)

So how exactly and at what step did you lose or corrupt that partition?

While I (hopefully) backed up mine, it is questionable to be of any use as the question arises how you'd edit it to make the proper adjustments to match your phone. After all, data such as IMEI & Co. is specific to the exemplar you have and thus cannot simply copied without risking to provoke conflicts on the network / operator side.

Was coming from 420 rom. Went to reflash TWRP doing a total format and wipe to boot into rom and I noticed that I didn't have signal. Lol and behold my IMEI showed 0 couldn't get back into TWRP, it just kept restarting back into system. I flashed back to stock and still 0. My laptop finally gave out as it is 11 years old. I lost 2 backups along with everything else. My box doesn't have the full IMEI because it was partially torn . At this point I am willing to try anything to get my phone signal again. Damn I hate this happened. Lol and no I don't blame the rom. I am really in a bind though.

Don't know if already solved it.
But here is a suggestions. You may have corrupted the permissions of the efs folder. You need to correct them. Then Odin flash the default Rom. This should work.

The laptop died, but is the hard disk operational? As your LAST resort, You can remove it, and with the help of a usb adaptor you can connect it to your new laptop as external HDD, then recover the backups you made. Beware, the USB adaptor has to match the old HDD interface (SATA, PATA, etc)
 
Can anyone tell me why my service provider line is missing something

    Dear friends
    I have consider to make this ROM as there is no active development on Fold3 and everyone should thank to @pvillasuso for pushing me lol! ROM made within couple of hrs and that without having device so may some bugs expcted, but according testers, stable enough for release.
    Also thanks to all testers who have tested and reported. I may not be able to release ROM with every new firmware but will try my best when time permits.
    Again thank you all for showing love & trust for Dr.Ketan ROM

    Important :


    - This will void warranty.
    - As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA won't work once you root device.
    - ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Installation :
