[Omnia 7 General] misterxp:
Hello all. I am very sorry to bother you all but I have been trying to upgrade my phone for the last 4 months and have almost given up. I saw the film about noods and really left it to the last resort! have an OMNIA 7 on:

7.10.7740.16 trying to go to 8107 for now but would like to go to windows 7.8 if possible

Fimware: 2424.11.112

Boot loader 6.4.09

I tired Zune: got error 80180008

Asked Microsoft: no help

Read forums and tried cab sender to send 8107 (+ languages) by Heathcliff: got same error but now know a bit more helphowto.cab.pkr	ERROR CODE: 0x80180008 invalid signature ) (. (thanks Heathcliff!)

Tried sending firmaware: worked!

Tried sending just language packs (got 6 on my phone) only partial loaded to 7.10.8099

I Read more on forum: tried sending certificates to phone by e-mail. Tried installing various certificates on computer. Tried sending a previous help how to cab (from previous O.S. cab via e-mail to phone (thought it might be missing). Tried partial unlock but, as expected, did nothing.

After reading more on this site, I have seen that the certificates have expired on the CAB files (downloaded from "force ugrade") and so guess it has nothing to do with phone or windows (tried windows xp, vista and 7 ultimate). Asking for a new cert. seems like playing tomb raider to me.

.details about error:

Phone works OK except for key board drop so it is not the end of the world I guess. As a last chance I would be to try seven eighter. I have seen that some people even stuck on 7720 have been able to upgrade. However, In one thread you said we can’t roll back. Another one you said it SHOULD be possible to burn a back up back to the phone.

I have seen other questions on ths and other forums about error 8018008 but I have not found an answer that helps.

I Know it is my problem but if someone could find the time to help to answer these questions:

1.	to burn a back up back to the phone, will cab sender work ? I have read that zune does not.is there another tool? The tool heathcliff mentioned, does not work with the latest version zune.

2.	I have seen other people on 7720 been able to go to 7.8 with seven eighter but I have seen they have had someproblems (I think mainly due to wrong language pack selection issues)-. Do you think it would work for me even if I get this error? If there was not a problem of rolling back I wold gve it a go.

3.	Is there something else I can do (except buy a new phone)

Thanks and sorry if this is in the wrong place or I have broken any rules un- intentionally !
