As I had stated in my earlier posts, the decision to remove side thruster have cost us dearly.Let's think logically
comms stopped while the lander was still descending
Due to inappropriate functioning of the thrusters the lander was most probably subjected to high G forces and related stress and strain while still in flight when the comms snapped.
this means some components inside lander were subjected to higher than rated g forces.
So as i previously alluded lander must have landed , but there was comms failure due to possible malfunction of some comms equipment . Higher that expected G forces might have induced anomalous behaviour in the comms component like displaced linkages or unintended transient voltage transfer / voltage spike causing shut down. unfortunately I have no understanding of the working of the same in space systems. So not 100% sure.but Similar power failures happened with isro satellites power bus.
The onboard TX/RX system requires the onboard data processing package to process data and format it for transmission over the same and vice versa after receiving the data. TX/RX system is working but the backend system which processes the data to be sent or be received seems not to be working at the moment.
The power supply from battery if bypassed for the secondary power source the solar panels , then there exists a possibility that the anomalous condition with the effected components of the comms system might get resolved and the system might reboot.
Eg in a normal oscilloscope if it is subjected to out of range voltage beyond instrumented range , the output readings flatlines and shuts down to recover and then reboots if the surge voltage is no longer present.
So same recovery can happen with the landers malfunctioning components provided the anomalous cause ceases to exist .
Good news inspite of the problem of communication with the lander, India now is the defacto 4th nation to land its own lander on the moon. Landing might not have been the smoothest but still it landed on its 4 legs.
Thermal image confirms it , why would ISRO try to re-establish comms if the lander is sideways or upsidedown ?Not confirmed
They should really put that image out in public.Thermal image confirms it , why would ISRO try to re-establish comms if the lander is sideways or upsidedown ?

Yes, it is confirmed by Twitter handle of ISRO chief.Not confirmed

Communication link is open but no data is being sent or received at the landers end atleast for now.

ISRO chief says "Yes, we have located the lander on the lunar surface. It must have been a hard-landing", he added. So, it might not be on its 4 legsThermal image confirms it , why would ISRO try to re-establish comms if the lander is sideways or upsidedown ?
It will come in due time, let them do their job first in which they are best out there.They should really put that image out in public.
Chandrayaan 2 lunar lander Vikram has been located on the moon's surface and the ground station is working to establish contact, news agency PTI quoted ISRO chief K Sivan as saying today.they have not said anything. You are just speculating. In fact NDTV reported that it seems to have been a hard landing. Not a crash, but not soft either.
The image above shows it to be nearly intact.They should really put that image out in public.
It might be, it might not be. Let's give them enough time to do analsis, then we can do our thing always as we do. Thank you.ISRO chief says "Yes, we have located the lander on the lunar surface. It must have been a hard-landing", he added. So, it might not be on its 4 legs

There are rumors on web that it might be fake twitter handle and some saying it is original. However national broadcaster is original which has said same thing.that's a fake handle.

I don't where we differ!only things said are
- we have identified the lander
- we are trying to establish communication
- it speculated that it is likely that the lander was not significantly damaged/ completely crashed or else they will not attempt to communicate- you can't communicate with rubble
- some people say that it is 500 mts away from landing site. It is unconfirmed and speculation until confirmed.
