Can't install apps on Nokia 8110 4G after installing GerdaOS — need sideload method or original KaiOS ROM/backup
Macro hernandez
Hi everyone — I need help with a bricked-app situation on a Nokia 8110 4G.
Short
version: I bought a brand-new Nokia 8110 4G to test apps and try
community ROMs. I installed GerdaOS (no backup was made because the
phone was new and empty). Now I can’t install any
apps: GerdaOS has no app store by default, and installing from the
phone’s browser fails. I tried sideloading from two different PCs and
different browsers/OSes but nothing works.
What I’ve tried so far
Installed GerdaOS (no backup beforehand).
Enabled Debug mode on the phone and Storage over USB.
Tried sideloading/installing from the phone browser (fails).
Tried installing apps externally using Pale Moon and Waterfox on two different computers (Trisquel and Devuan).
Tried various Banana Store apps; none install.
At one point I did manage to install Wallace and get root, but now even Wallace won’t install back.
I found a ROM named KaiOS_2.5.1_for_Jio_F90M.zip (from a Banana Hackers group) that claimed to be based on a similar device — I tried it but it was not compatible.
I can connect via USB and the phone
shows debug/storage, and I can tinker with settings, but I have no
store or sideload method that actually completes installation.
What I’m asking for
(Preferred) Any clear, tested method to sideload/install apps on GerdaOS when the system has absolutely no stores/apps installed. Step-by-step commands (Linux) or tools that work with Debug/USB mode would be incredibly helpful.
(Alternative) If someone has a working backup/ROM of the Nokia 8110 4G (KaiOS stock)
or a GerdaOS image that already includes an app store (Banana Store /
equivalent) and is willing to share it (or point me to a reliable
download), I would be hugely grateful. The image or backup should let me
restore a working environment where I can install apps again.
Any pointers to the official
Nokia/KaiOS stock firmware for the 8110 4G, or reliable sources where
original KaiOS images are hosted.
Additional details that might help
Device: Nokia 8110 4G running GerdaOS (installed by me).
PCs used: Trisquel and Devuan (both Linux). Browsers tried: Pale Moon, Waterfox.
File I found: KaiOS_2.5.1_for_Jio_F90M.zip — tried, not compatible.
I can provide logs, console output, or screenshots if someone tells me what to capture.
Smart U.

Hi, I've tried the links you provided and attempted to install the system using the recommended version. However, I keep getting the same error: "footer is wrong, signature verification failed, installation aborted." I have the Gerda OS recovery; I'm not sure if that's the problem. Although the link says it's the recommended version, I'm not certain.
