I have 2 GT P7500 tablets.

One is not booting up at all (Power + VolumeUp/Down doesn't work either).

Second one is displaying this:

AccessParamData: Fail to NVstormGRPartitionQuerryStat [err:0x3]
OpenParam: Fail to AccessParamData_read [err:0x3]
Error -> NVAbootGetPartitionParameters [err:0x4]
AccessParamData: Fail to NVstormGRPartitionQuerryStat [err:0x3]
SetPAram: Fail to AccessParamData_write [err:0x3]
Error -> SetParam(ParamIndex_secure) [err:0x3]

Am I correct in assuming both (or at least second one) is badly flashed and therefore bricked?
