my postmarketos tricks

for samsung devices, to avoid touchscreen being frozen after a while of IDLE, even if the system responds

just add a screen.sh script, eg in your /root, that you might add eg every 5mins, within your crontab :

  • /5 * * * * /root/screen.sh

screen.sh containing as follow : /sbin/modprobe -r zinitix /sbin/modprobe zinitix

dont forget to chmod +x screen.sh !

for every linux distro, i also recommend to add to your /etc/rc.local, as follow :

/bin/touch /forcefsck /bin/touch /home/forcefsck

Grand Prime LTE, G530FZ postmarketos/Phosh

I really disadvice to run firefox on it : hardware is huge too low specs and browser might run **very** slow and even crash the system, until a reboot is done. i recommend either receive news using RSS, or browse with dillo. dont expect proper common web browsing or even JavaScript browsing run smooth on this device, it's highly too old/low specs.

Grand Prime LTE, G530FZ : roll back to androstock/lineageos?

for G530FZ:

used: twrp 1.1.1-1

lk2nd (postmarketos): 0.12.0 msm916

android stock

download mode

simply use odin with a tar ROM

lineageos

download mode

use heimdall or odin to flash the twrp used: twrp 1.1.1-1

twrp/recovery mode

use twrp to flash the lineageos zip file (install button) I really advise you to use lineageos14.1 (andro7) for better compatibility/performance

well tested:

lineage 14.1, but you *might* have to odin it, regarding this:

Hi guys

regarding the G530fz to solve the problem I had to be oriented to Lineage 14. Why the cell data was not detected? I don't know, but I discovered a way to fix it: I was used before to install Lineage by just injecting the image file into the phone, then format the /data partition by simple wipe. And for others phone, it was working. Looks like on samsung models, it's requiring steps differently:

1/ use odin to reinstall stock firmware regarding all four files: BL, AP, CP, CSC. In the downloaded archive of the stock firmware, all files matchs with those option with odin. It's necessary to add these four files. Flash it

2/ The phone will start. After finished, you can restart it, but in download mode.

3/ then use again odin, but flash it with only three files, excluding AP. Replace BL by the twrp bootloader.

4/ If at reboot, it's stuck on a recovery start, even without pushing the vol buttons, reflash it again with only BL.

5/ proceed normally to install lineage: download correct image plus arm (it's arm32 if Im right) pico or nano opengapps, copy them to the phone by usb, flash it then wipe /data.

6/ it should work.

If not, I remember I had to firstly flash by stock factory with all four files of stock archive, then only three including twrp instead of factory BL, then only BL if it's booting in loop into recovery instead normal mode.

Normally, it should, with lienage, detect sim cards. If you just flash it with twrp by BL/odin, twrp will be installed, lineage can be installed too, but GSM/3G/LTE modules might never work (in my case, it happened like it)
