In an effort to get a WiFi adapter working I was following instructions on replacing a file called 'linker' in system/bin. Before copying the new linker file you gave I renamed my old one to linker2 because I wanted to be able to revert if needed.
After I renamed linker to linker2 my phone said I didn't have root anymore and I couldn't rename the file back.
I restarted and now am encountering an error that prevents booting. I'm in Android System Recovery with options:
reboot system now
apply update from ADB
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down view
recovery logs
apply update from sdcard
If I select 'apply update via ADB' I can use ADB from my laptop, but seems the only thing I can do is sideload a file. Is it possible for me to sideload and execute a simple script to rename that file back to linker instead of linker2?
Help is greatly appreciated.
