Hello Voloviq,
sorry to hear your were not able to generate the toolchain.
To resize partitions you might be able to use at!apppartchg?:
at!entercnd="A710"
OK
at!apppartchg?
Total APP partition size: 253952 kB
APPSBL,PAD,APPS,PAD,SYSTEM,PAD,USERDATA,PAD,USERAPP,PAD =
896,128,20096,384,50048,384,37888,2560,140288,1280
OK
at!apppartchg=896,128,20096,384,150048,384,37888,2560,40288,1280
OK
at!reset
It will wipe the data on your device though.

The only thing that you have to be careful about is to keep the sum equal, and not to touch the padding (PAD parts, not sure the effect that it would have).
The original configuration was SYSTEM=50048 USERAPP=140288.
I took 100000 from USERAPP and added it to SYSTEM (=rootfs):
Before = 896,128,20096,384, 50048,384,37888,2560,140288,1280
After = 896,128,20096,384,150048,384,37888,2560, 40288,1280
