HOW TO: downgrade, root and upgrade ANY G1/Dream (even Continental European)

[moneytoo]

Ok, so you have firmware v. 123099 and wanna have root access... no problem.
I have just succesfully downgraded mine, 123099 to RC7, and then loaded ADP1.1h.

QMAT public (free) version used to succesfully downgrade with WM device: qmat_424.zip, md5: 7f0ccd1b52072bc2a6d594393f2ce348.

Newer QMAT can create Goldcard only in paid version. Buy it or get the old one somewhere else (giyf). You won't get it here or from me.


Requirements:
- Micro SD card formated FAT32 (128 MB to 2 GB), Sandisc cards may not work (but worked for me).
and
- Connected Windows Mobile device (application unlocked)


SD Card:
- Format recommended

format F: /FS:FAT32 /A:4096

(Replace F: with your SD card reader drive letter.)


TESTED, WORKING
1. Insret SD card to WM device and connect it do desktop. WM has to be application unlocked.
2. Download QMAT (http://revskills.de/pages/download.html)
3. Start QMAT and select Hardware Forensics -> Generate HTC Goldcard
4. Select Dream from the list of devices, Click "Get SD Card Serial from WINCE Device" and then "Save Goldcard Image to WINCE SD".
5. Copy DREAIMG.NBH to the root of sd (UK - RC7 recommended for our DREA110)
6. Power off the G1, put the card inside, hold camera button and press power button
7. Press power button to start flashing
8. To apply HardSPL, root & upgrade: http://forum.xda-developers.com/showthread.php?t=442480
9. You don't need the GoldCard any more (HardSPL fixes it, you should be able to flash any image now). So format the SD once again or borrow to a friend to downgrade his G1.


Other way: No WM device needed, just Linux (or Cygwin, to use dd) and paid version of QMAT. However this may not work (incorrect sd card serial number read from G1).

This is great news, moneytoo you are the king !

I did some reading at the links you gave and I believe in theory instead of using a windows mobile phone for QMAT, you can create a HTC goldcard and distribute that image for any HTC Dream downgrade.
Nope that doesn't work

Can anyone confirm, that this methode is working ?

Hi, read again.
Requirements:
- Micro SD card formated FAT32 (up to 2 GB), Sandisc cards may not work (but worked for me)
and
- Connected Windows Mobile device (application unlocked)
or
- SD card reader and other way of getting SD card serial number

2 way to do. first or second -- connect WMD or card reader to get serial no of card.

I have a Windows Mobile Device but only with SD Card support but no micro SD.

But as i read so far, the only thing you need the WM Device for is to dump the micro SD serial number. So we just need to find another way to read out the number from the G1 directly... ?!

Get a microsd adapter. MicroSD cards are 100% compatible with SD hardware.

I have downgrades my German RC33 to UK RTC7 with this method, It was very easy to create this HTC Gold Card. Next Step ist a custom Firmware.
