HELLO
I HAVE DELL STREAK COME FOR UNLCOK O2 OPRETOR VERSION 1.6
SO I UPDATE 2.2 & DELL LOGO COME , THAN I BACK WORKING CONDITION
WITH
1) Put the official dell 6941 pkg on SD root called Update.pkg
2) Flashed stock recovery using fastboot
3) rebooted into recovery mode (holding down the volume buttons)
4) Selected number 2,
Flashed the 2.1 build back using fastboot and still no radios working. Also when I check the phone info there's no baseband version info, which could explain why the radios don't work.

Stuck at Dell Logo Boot Loop

I'm not sure if my phone is bricked now.
At boot up, it just shows the Dell boot logo, and than dissapears and than after a few seconds the dell boot logo reappears. It keeps doing this in an endless loop.
I tried to boot into the recovery menu, but in the general menu it crashed once, and so I tried to reboot the phone, and that's when the Dell boot issue start.
I have clockwork mod recovery and Cyanogen Mod 7.2RC, and the phone had been working great for a month. I'd normally just restore my ROM, but I can't even get into any of the different recovery menus, I can't even get into the fastboot mode, since after the Dell boot logo, it keeps looping back into the dell logo.
I tried with vol up, vol down, up and down, with the phone in vibration mode.
Any ideas? Really like this phone, don't want to have to replace it.
Think there's any cellphone repair stores that could repair such an issue? IS it possible the pre-boot mode is corrupted somehow? Although I would imagine that's boot ROM that's write-protected?
So confused :crying:
