[Q] SM-T310 died when wiping in TWRP, now "unable to mount cache" anyway to recover? topic

My TAB 3 8.0 SM-T310 died during wipeing in TWRP for some reason. Now I am stuck in recovery or download mode. TWRP is unable to install or wipe. I only get failed "Unable to mount cache" what ever I try to do. Is there anyway to help this tablet ? Thanks

[Q] Samsung Tab 3 8.0 SM-T310 firmware topic

Hi,

I work for a large electrical retailer and when new models come out they allow us to buy the demo units from the previous model at a reduced rate. (I'm more than happy to SS a receipt to prove the unit isn't stolen etc)

Normally I just disable the demo mode and reflash with a stock firmware that I get from samsmobile, however samsmobile seems to be having issues and the firmware gets to around 60% then interrupts and upon restarting says immediately that it is finished, of course its only got around 800mb of a 1.3gb dl. I have tried serveral times over the course of the past few weeks and from different locations but same thing happens.

I can't post in samsmobile forums as I'm not a premium member so don't have the permissions. Is there anywhere else I can get the official firmware?

Kind Regards
