There is another explanation. It could be that the K-152 was build to an "export-standard" and lacks the sensitive tech and equipment that is available on Russian boats (eg she doesn't have SOKS). Costs to fully retrofit and repair her for Russian service are probably sufficiently high that the money would be better spent on a new sub of more modern design. IIRC she is in Vladivostok and Amur yard is not yet up to repairs/refurb of nuclear boats, so would need to be transferred to somewhere like Sevmash or Nerpa yard (I expect these boat houses are all spoken for).
I can't imagine that the hull(s) can be so damaged by a failure of a compressed air cyclinder that the K-152 is beyond salvage. The Indians patched up and sailed her to Russia under her own power. Doesn't sound to me like a boat that is irrepairably damaged, so there are clearly other factors at play here.
