I’m new to HighOnAndroid, new to Android phones in general, and I’m just about tech-savvy enough to be dangerous.
I want to load TWRP, root my phone, and load the Lineage 17.1 (stable) custom Rom on my stock Samsung Galaxy S7 (SM-G930F).
Having spent a few days trawling the web, I stumbled upon Max’s really excellent v-logs, which seemed as if he might have created them with someone like me in mind.
Now to the problem:
Despite evidence to the contrary I am absolutely convinced I have followed Max’s instructions to the letter…
Using the links provided I downloaded:
I used Odin to install the TWRP tar ball (The Samsung USB Drivers were not required)
Booted into TWRP on the phone
Attempted a backup to the SD card TWRP reported it could not mount /Data and the back-up failed, so I found a fix on the XDA forum which involved formatting /Data as ext4 and then reformatting it back to its original ext2 which then allowed TWRP to mount /Data and I completed a backup
I copied the other files across on to the phone’s SD card
used TWRP to install no-verity-opt-encrypt-6.0.zip
rebooted into recovery and the “read only” warning screen had disappeared
Performed a full Wipe (Swipe to confirm)
Wiped the Dalvik / ART Cache and the Cache using “Advanced Wipe”
used TWRP to install Magisk-v19.3.zip
rebooted the system and verified the Magist app was on the phone
Obtained LineageOS and GApps from here:
These were the two files downloaded:
Copied these files over to the SD Card
Rebooted the phone into TWRP
Used TWRP to install lineage-17.1-20210409-UNOFFICIAL-herolte.zip then (before restart)
Used TWRP to install open_gapps-arm64-10.0-stock-20210428.zip
Rebooted the phone
…and this is where it all goes wrong.
Instead of booting into the anticipated Android LinageOS 17.1 what I get is:
The Samsung Galaxy Logo
Then a blank screen
Then a light-blue curved line (like a sad mouth) is drawn right to left,
and then a small dot appears on the right of the “mouth” which travels along the arc of the “mouth” from left to right whilst growing into a circle.
The arc and the circle disappear and the cycle repeats (with the arc being drawn in a different part of the screen.
This continues for about 5 minutes. Then the phone restarts and boots into TWRP recovery.
Clearly, I have missed a step, or done something wrong… But I don’t know where to start.
Does anyone recognise this behaviour and what do I need to do to fix it?
PLEASE is there anyone out there who can help?
