...

is it fixable or is it a hardware problem?

thanks in advanced

I tried to restore to default (factory) settings but the error is the same, ..... "Unable to save backup partition table! Perhaps the 'e' option on the experts'

unfortunately I had to leave for work and I only have time to deal with this subject on the weekend ...

I thank you very much for your attention.

hi!

i try this

flash-rescue /tmp/*.bin

got this

Fatal: Cannot access '/tmp/*.bin'

i also try fdisk -lu /dev/mmcblk0

and get fdisk: can't open '/dev/mmcblk0': Input/output error

so i think that the flash memory is almost dad.

can someone confirm my suspect?

thanks

i will try

thank you

thanks for the help,

i have already contact Johny, ...but i will first try some more firmware/software stuff, before open the box and do some electric measures.

If nothing go fine, i will try to sell the box, maybe some expert guy will buy it and solve the problem easily, ... with the money earned will grab another dreambox (dm920).

This weekend i will try all other options, ...

Thank you all for the suport

.

After try everything, with my limited knowledges i need to move on, and try a new toy to play with... i´m not shure about my choices, can someone please write about their expiriences ... dream box two or Vu+Duo4Kse.

My primary needs are:

good/best image quality

change firmware easely

share tv with my mobile equipments

good brand/image suport.

My tendence is dream, because i alway had this brand, but most of the people i know have VU and alway tell me to go to VU, because of support, but i think that now a days dream have more suport than other brands...i´m wrong?

Ps: i´m selling my Dreambox DM900 Ultra HD 4K - Tuners: Dual DVB-S2X MS

thanks

Quote from naiarty

I hve an Dreamtwo now but ithink s very limited no open image just deb. and soft for 64 biti is not verry simple to find.First receiver is one Vu D=Solo 2 Duo i liked after that i buyed one Dreambox 900 HD, both was good for me,problems is the Vu Duo is good but old and now may be soft go to python 3 so if Dramtwo will have more suport may be this is now newer the coice is your.

thank you !!! :thumbup:
