[myTouch 3G, Magic Android Development] stilbon:
Confirmed

It looks like I might be fixed after following the excellent work by ezterry in another post - /showpost.php?p=5440198&postcount=6

I'll quote it in its entirety here:

==============================================================================================

OK,

Good news:

Cyanogen -> Rogers patch 1.5 and back (and added bonus for linux/mac users no need to run a windows application to do it)

Bad news: in writing this and redoing the process I did something silly and bricked my phone: (so continue with caution)

Here is a hacked version of the dream rom.nbh used to update to Rogers new version. (Basically just flagged it not to touch the SPL)

You will need:

* recovery-RA-dream-v1.5.2R.img

* DREAIMG.nbh For Rogers 911 fix

* working fastboot

* Engineering SPL (others may or may not work)

* RADIO-2.22.19.26I users: signed-dream_devphone_userdebug-ota-14721.zip or radio image

(edit) NOTE this will likely only work on rogers phones

1) download http // rapidshare.com/files/340176423/DREAIMG.nbh.html

2) Place this version of DREAMING on the root of your SD card

3) run Nandroid backup!!! (this also ensures your current recovery works)

4) turn off phone and turn on holding camera

5) Start HBOOT mode (may start on its own, otherwise press "send" to go to FASTBOOT then camera to return and re-try HBOOT)

6) it will ask you to install [1] RADIO_V2 [2] RECOVERY [3] BOOT [4] SYSTEM [5] USERDATA

7) press action key (trackball) to install rogers firmeware w/o SPL

8) wait while install continues

9) When prompted to reboot hold camera while you press the action key

10) Now back in the SPL use fastboot to flash recovery-RA-dream-v1.5.2R.img (fastboot flash recovery recovery-RA-dream-v1.5.2R.img)

11) Menu to shut off

12) power and boot into rogers rom

>> You now have a non-rooted rogers rom with the rogers radio;

>> however you have fastboot with engineering SPL; and a full recovery image

If you where using radio 2.22.19.26I this will need to be recovered and nandroid restore run; otherwise hopefully you only need the nandroid restore (not tested by me)

Restore Cyanogen and other EBI0 roms /Radio 2.22.19.26I From a previous Nandroid backup ONLY:

1) boot into recovery

1.b) run Nandroid restore and restore your last backup (*Edit added*)

2) reflash radio image (simple way: Flash signed-dream_devphone_userdebug-ota-14721.zip) DO NOT REBOOT YOU WILL BRICK YOUR PHONE

3) goto Backup/Restore -> Nandroid restore and restore your latest backup

4) once done use Home + Back to reboot the phone + install radio image

Restore Cyanogen (EBI1) From a previous Nandroid backup ONLY:

1) Run Nandroid recovery

Install CFW:

Follow rogers install instructions

EBI0 roms: you have only installed the SPL; you will still need to install Radio + recovery

EBI1 roms: you have already installed SPL + Recovory

Edit: Added step 1.b; this ought to prevent fully bricking the device if you accidentally reboot. (not that the restore will be fun)

==============================================================================================

Hopefully you haven't put the official rogers patch in yet, or your SPL is gone and you're probably out of luck.

My original setup (Dream):

DREAM PVT 32B ENG S-OFF

HBOOT-1.33.2005 (DREA21000)

CPLD-4

RADIO-3.22.20.17

I followed ezterry's rough layout, fortunately I don't have the 2.22.19.26I radio he spoke about, as that's where his instructions made me a little nervous.

Applied the .nbh for the 911 fix that ezterry has provided a link for and laid amon ra back in. Rebooted into fastboot and it was still there - and so was my 1.33.2005 SPL!

Rebooted into the Rogers rom and let it take its time to lay in the new radio image.

Now I can bounce between the rogers updated rom and cm4.2.13 at will, so I figured what the hell and restored cyanogen to test if the rogers scan was simply looking for the radio string. If it didn't, then I'd just put the rogers rom back in and wait to be blessed before restoring.

New configuration:

DREAM PVT 32B ENG S-OFF

HBOOT-1.33.2005 (DREA21000)

CPLD-4

RADIO-3.22.26.17

So my radio has been pushed up. This was finished last night before midnight. I left the phone on all night and this morning there was still no data. When I got to work I figured I'd try a battery and sim pull - and voila! My 3G is back - no call needed to Rogers for a refresh.

If you have the same phone version, feel free to give it a try so we can get some more confirmation from someone other than a 'Junior Member' ;) . Just remember (if you have the same radio version as me) not to worry about ezterry's instructions about the old radio - you won't need the old radio file, nor do you need to do reflash the radio image he mentions later. You only need to do the nandroid restore if you kept your EBI1 radio like I did. As always, YMMV, don't blame me if your phone tanks :)

Hopefully the scan is a whitelisting thing, but if I have any issues I'll post and update. Good luck.
