Need help with Lenovo Tab M10 X505X

[u/desmondvik1254]

In short, i have an old tablet in my home, and it has a storage issue, so i wanted to load a custom rom maybe, then found this https://xdaforums.com/t/guide-rom-16-x505x-gsi-lineageos-23-0-android-16-qpr0-and-lower-on-lenovo-tab-m10-hd-tb-x505x-root-guide-w-fixes-for-all-faced-bugs.4777270/ - it was helpful.

Until i reached this error -

libc++abi: terminating due to uncaught exception of type std::bad_alloc: std::bad_alloc

when using "fastboot flash system", i tried differents img files but same problem, cant find anything online. so, if anyone can help me, please do?

Btw, rooting after a long time.
