LineageOS 19.1 (Android 12L) [Signature Spoofing][OTA updates] for S7 Exynos

[netra3441]

Hello Ivan
Ever since latest update (Nov security), phone does not fast charge at all.
I have tried with different chargers on different outlets
It now takes at least two hours to charge from 15% to full.

(I have checked, fast charging is enabled in settings)
Phone is standard Europe model. Thank you

Well, I use my Samsung Galaxy S7 since I bougth it in 2016. But never charged it fast. Telling the truth, I did not knewed, that this can be charged fast. And because its a very old mobile phone, I am not sure, if a fast charging would not damage the battery. So, maybe your fast charging problems have their reason now in a damage of the battery, because maybe you had charged the S7 with fast charging too much.

I have a routine for charging. In all my rooms I have charging units, and can charge everywhere in my apartment. So I never forget to charge, so I do not need the fast charging at all.

check the cable, that is usually main cause for phone to not fast charge, also if you have any sort of kernel manager apps remove them they can interfere with fast charging hal

It depends on, wich provider you have.

Thank you! In the meantime I found the reason for this issue. It was the DNS server in Settings > Private DNS. I switched to Automatic and tried another DNS server. Both methods work perfectly.

@netra3441 or anyone else for that matter:

I have this up and running on my S7 (thanks again, @Ivan_Meler !) however it seems there is no way to enable full-disk encryption as you lose the ability to access the storage within TWRP. Looking into it here on the forum (unless I am missing something), it seems some years ago TWRP lost the capability to prompt for the passphrase for decryption to work. I've also tried manually unlocking it via the built-in terminal to no avail. Am I missing something? Unfortunately, I need this functionality (not just because I am a security freak but also because I need to use Duo mobile for work and it required FDE).

Any help is greatly appreciated. The last posts I saw on the matter ended in 2016 due to the phone being considered "old".

well sadly twrp cant use hardware backed encryption, you can use lineage recovery however (its in rom zip) its quite basic and doesnt have backup and restore functions but its useful as recovery as it can handle updates and thats what matters the most

Thanks, @Ivan_Meler . Can I assume this is installed in the usual manner with `heimdall flash --RECOVERY ...`? And does that still grant me access to anything I may need to install via the recovery (say, how I can install NikGapps via TWRP currently)?

yep, just keep in mind you will have to install stuff from either sdcard or adb sideload, you can install it with heimdall or using dd, either will work

@Ivan_Meler that worked a charm, thanks!

Hey all, found this page earlier today, and have been trying to update my stock S7. Cant seem to get twrp installed. I reset the phone to factory default, didn't set up any accounts on it, turned on usb debugging, and oem unlock. Tried putting twrp 3.7.0_9-0 herolte on it using odin 3.14.4. Odin can see the phone but fails. Phone goes into a screen that says to use smart switch emergency recovery. That doesnt work, but I can get the phone going again using frp hijacker. What am I missing? Seems like it should be fairly straight forward, but I cant get past this point. Any help would be greatly appreciated.

You need to make the phone boot into the recovery first after flashing twrp with odin without booting normally iirc.
So.... disable "auto reboot" in odin and after flashing it, hold power+home+vol DOWN, then immediately after the screen flashes, swap to holding power+home+vol UP.

Thanks for the reply. The issue I'm having is that I can't get TWRP onto the phone in the first place.

Thanks for the reply. The issue I'm having is that I can't get TWRP onto the phone in the first place.

I suggest to first wipe phone completely by flashing stock factory image via Odin.
If that doesn't work, phone has FRP issue.
If it works, you may follow

Spoiler: Installation Guide

Here a detailed Instruction:
========================================================
1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.

2. Now go to Settings -> Developer options. (above About device)
You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.

3. Extract Odin to your computer.

4. Install Samsung Mobile Phone Drivers for Odin to find your device.

5. Download a .tar image of TWRP for herolte.

6. Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.
Once you reach the Download mode warning screen, press [Volume Up] to continue.

7. [Optional] Install latest Bootloader / Modem firmware:
Open Odin and place the Bootloader in the [AP] and Modem in the [CP] slot.
Disable Auto-Reboot Option, then press [Start].

8. Open Odin and place that TWRP tar file in the [AP] slot.
Disable Auto-Reboot Option, then press [Start].

9. Hold [Volume Down] + [Home] + [Power] to get out of Download mode and immediately swap [Volume Down] to [Volume Up] (continuing to hold [Home] + [Power]) when the screen blanks.
If you don't see then TWRP boot splash try again from step 6.

10. At this point, you will reach the screen asking you if you want to allow system modifications.
By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot!

11. After allowing modifications, go into Wipe and choose Format Data option
(no need to format differently and then format back again)

12. REBOOT back into TWRP recovery again using the option in the reboot menu

13. Download the latest ROM for your device.
Without exiting TWRP, transfer the ROM zip to your device over MTP* and flash it using [Install] in TWRP.

14. [Optional] Download the latest GAPPS for your device.
Without exiting TWRP, transfer the GAPPS zip to your device over MTP* and flash it using [Install] in TWRP.
Important: Flash Gapps and Mods right after Rom Installation, no reboot in between!

15. Go to [Reboot] -> [System].

12. Wait 2-5 minutes for your device to finish setting itself up.

Thanks for the reply... That guide looks good. As for the wipe, a factory wipe is not sufficient then?

Yes. There are always a lot of ways beacon to the city of Rome...

Hi all. I've tried a few times to install this along with gapps MindTheGapps-12.1.0-arm64-20220605_112439.zip. I've by uploading the 2 files to the phones sd card and using WRTP to do the install and also using adb to sideload through TWRP. In the both cases LineageOS installed fine but in the 1st case there was a error installing gapps and in the 2nd case everything *appeared* to install ok but when the phone boots there are no Google apps so I have no way to install apps. Is this normal or have I been doing something wrong?

I used Odin to flash TWRP but the very latest version fail so I had to use the next version down on the TWRP downlaod page. The LineageOS file I'm using is;
lineage-19.1-20221109-UNOFFICIAL-herolte.zip
and Gapps is;
MindTheGapps-12.1.0-arm64-20220605_112439.zip

Hopefully somebosy will be able to help me sort this out as Lineage 19 looks nice
