issue after updating apps (banglejs1)

Recently i was updating apps from GB Apploader, though i was receiving a messages "...JSON malformed.." i keep updating and some apps were updated but one never completed the process.

Later i began seeing debug messages on watch screen, and graphs overwritten with a wrong position

Now the watch is broken, after checking storage, bootloader and settings are not installed.

It assume that during the update process they were uninstalled but installation step failed. (as i was doing from the phone I didn't realize)

If i try to install "bootloader" i get following message

FW addr 0x0001a168 fail
Status 0
Uncaught Error: File already written with different data

...xlPDAuMimrO2cucw=="),0,4945);;p(24);B­luetooth.println("OK")..

but installing other apps also fail

Any alternative to earease.all and reinstall basic/default apps?
I see that "install default apps" implies a removal for all apps. (i don't mind but i was not expecting it)
