304 update problem

Hi, I realize there are thousands of posts on this topic so first off I apologize if my answer resides as a needle somewhere in that haystack. I have 928Droid BGX2.3 installed. Haven't done anything really since 2.2 came out except maybe tried a rom here or or there but always went back to this one. I am on 2.3.15.MB810.Verizon.en.US rooted & deodexed.

I received a prompt for the 340 update the other night and after pushing it off a few times... backing up my rom... i tried to install it. It failed.

I read some posts about 928droid's "back to stock" rom and I thought i could load that and retry the update.
Well, hxxp://www.928droid.com/ is down and i cant find it anywhere so that's not an option apparently.

So 2 questions I guess:

Is there a way I can update my phone to 340 without losing my accounts/apps/data? if yes can someone point me to instructions/guide for my situation?

If I have to SBF (which i understand wipes all data?) Can someone point me to the right one because i read all this stuff about SBF'ing the wrong bootloader and people getting bricked and I don't want to make that mistake.

Lastly there is a stock 2.2 rom image if you look at the roms available for download through rom manager. It says "must have 2.1 installed"

I have 2.2 does that mean i cant load that and try to OTA to 340 from that?

forgive my Noobness and I really appreciate any help/explanations anyone would like to offer.

Thanks!

 

Sorry about the link. I fixed that, must of clicked the button by accident.

Anyway I am at bootloader 30.01 hopefully that doesn't make a difference and I can use the sbf you suggested for 30.03.


I will check out your guide, thank you

 

well I read your guide and followed it. I SBF'd the VRZ_MB810_2.3.15_1FF_01.sbf file and it got to 100% instead of saying passed though i got this error:

Failed flashing process. Failed flashing process. Interface BP: Error sending RAM download for bootloader. Device API Error: 0xE0030009 Address: 0x18F000 Command: ADDR (0xE0231009);phone connected Progress

Executed 100% Result Fail

Any idea what thats about?

when it rebooted it seems to have worked though. Everything looks stock... but all my settings, apps, widgets, are there... However i did lose root


I did the 340 ota and that also now worked.

what is the best way to now re-root?
