[CLOSED] no sim(s) card working!!

Hello,
something very strange happening to my J7 2017 PRO, model (SM-J730GM/DS or J7y17lte) after I installed Crdroid 10.
Mobile cannot detect sim cards ! Help please.
I reverted to stock rom Pie Android 9.0 but same problem. What could have happened? Some EFS partitions deleted i read in some forums?
*How to restore telephony functions back ?
*Beside CrDroid, what other stable rom android 10/11 do you advice?
thank you so much

-You might have lost your IMEI. What happens if you type *#06# into the dialer?
-For a basic, stable ROM I'd recommend good old Lineage OS.

sims are not detected by OS and phone.
So, of course, IMEI is not there...

[CLOSED] Fake/Clone p40 pro

Hi folks!
Recently I've bought a p40 pro clone that is driving me crazy.
I can't barely use it as all the tweaks to make it look like a better phone are provoking some apps to fail. The about phone screen says that is a p40pro (without spaces), the CPU is a MT6799 when in reality is a MT6580, 12Gb of RAM but is 1Gb, Android 10.1 but it's 5.1, hahaha, it can't be more fake, but no regrets, I have what I've paid for!!!.
My initial idea with this crappy thing was to upgrade the android version to 6.x, but everything is pretty tough, at least with my little knowledge in custom roms, kernel etc.
First of all I'm not able to install TWRP on it. I can't find or make a working version:
I thought that this model was pretty similar and I tried with the TWRP included on the thread about a p40pro+, but the touchscreen after entering recovery was somehow inverted and seemed laggy: https://forum.xda-developers.com/t/alps-clone-p40-pro-wish-com.4211591/
With the one at https://forum.xda-developers.com/t/unknown-china-device-p40-pro.4200617/post-85249887 it don't work too.
Finally I came to this thread https://forum.xda-developers.com/t/...ediatek-mt67xx-64bit-new-32bit-phone.3681861/ and I managed to make a custom TWRP which initially seemed to work (the touchscreen was fine) but the sd card data was unavailable, I was like missing but if I reboot the mobile it properly boot. Maybe because I choose an incompatible model to port from.
So, I'm running out of ideas, please can someone give me a hand on that super ultra fake thing?
Here is the full rom dump, preloader and recovery:
https://mega.nz/file/2M80XY7C#0kw7qVQ5498tDrt4UdUNq49lANIO3RvS73ct6DoCPO0
I'll really appreciate any suggestion on getting a new rom for this phone, and obviously how to get twrp on it, root, and if possible a rom which makes this fakephone at least useable.
Zillions of thanks in advance!!! Take care!

root samsung a12 (sm-135f/ds) and recover deleted files

Hello everybody
the last android that I rooted was 4.2 I think.
Now I want to root a12 android 12.
I am trying to recover all deleted files.
All root methods say that I must wipe data. I think if I wipe data it will be more difficult to recover the deleted files.
I tried Dr. fone but it didn't recover deleted files.
Is there a complete way that can make me recover all deleted files from my galaxy a12??
best regards

How to get security updates on S7 herolte?

I have been using a Samsung Galaxy S7 phone. I just learned recently that it does not get security updates anymore, and I am shocked and appalled. What can I do to update the OS on it and get the latest security updates?
Would following this guide be a way do that? https://forum.xda-developers.com/t/...alaxy-s7-herolte-stock-to-android-13.4201187/
Note: I'm a programmer by trade and fairly technical, I just know nothing about phones.
Thanks.

Try a custom ROM, because Samsung stopped the update support for Galaxy S7
You could find anything you want in the modding section, but the Exynos variant is limited in it.
