I have tried to update my droid with update.zip. It failed with a weird message, smth like could not update modem (the phone was ok before)
Now i got mass of downloaded files, like rsdlite and two sbfs
VRZ_A956_2.4.33_1FF_01.sbf and DROID2WE_X6_2.4.29_FULL.sbf
both stop at 100% and i get a popup message telling new device is found QHSUSB_DNLD or something like that. I've checked ALL motorola drivers (5.2.x update) for subject of this string with the hardware id of PID_9008 but i have found nothing! It just simply DOES NOT exit!
I have found proper dirvers, it looks like MSM6600 default drivers. So when RSD switched to BP mode it won't see anything, tho i get the drivers running and in the device manager i clearly see smth like Qualcomm ..Download 9008 but the RSDLite keeps searching and fails to process - Phone disconnected...

So, maybe anyone here got the same problem or has a clue of how to get rid of bootloader screen? Wiping cache, erasing to factory does nothing, I don't just get what this rsdlite wants? which device appears when it switched to BP download mode? Isn't it the one i get?
I have tried 3 PC, 2xXP and 1xWIN7 so it's NOT the PC's fault.


RSDLite is 5.4.5 - latest, the drivers - latest!
Please guys, need your input!

EDIT: I have joined only 3 files: CG05, RDL1.smg and RDL3.smg to test faster - it will immediatelly switch to BP mode, so no need to erase or reflash whole device. Will upload to rapidshare if anyone wants to test.

Try http://www.droidforums.net/forum/dro...ezsbf-d2g.html — this is a bootable CD image (which can be also used with a USB stick) that performs the task.

Note: 2.4.29 is the recommended (at least by me, after quite some experience) image; it's best to update to 2.4.330 OTA.

Thank you.
But here is the fact:

"If you already use Linux as your OS of choice you can flash with your current system, grab sbf_flash and the SBF file then simply cd to where you put the files, then:
chmod +x sbf_flash
./sbf_flash filename.sbf"

I have Linux Ubuntu and i have tried it already. No use.

“No use” doesn't quite describe the problem, to be honest.

Ok it will flash it flawlessly, no problem. But it does not flash the BP module. It just ignores the fact that in package there are AP and BP firmwares, so sbf_flash will flash only the AP part.

I am not yet able to help but at least i can give an answer that will probably point into the right direction.

What actually happens:
Droid 2 Global has 2 CPUs : OMAP (AP) & Qualcomm(BP)
At some reason the update via sdcard or failed sbf flashing in BP mode erases the BP content and fails to write the new data into the nand/emmc(whatever), so Qualcomm will jump into Emergency download more each time the RSDLite will try to switch to BP mode, thus you will see the QHSUSB_DLOAD device (COM PORT actually) that's it.

The chip is CDMA1x QSC6085 so it barely has any security on board, making it possible to use any Qcom flasher compatible with the chip and + ramdownloader.

What to do:

Get a qualcomm flasher (PSAS or other tools)
Get a ramdownloader (boot loader) for the 6085 (can be found, for older phones)
Extract the original SBF file content and use the *.mbn files and flash it.

This way may help.
