[G2 and Desire Z General] prairie-dad:
Sorry, but not there yet. [SOLVED]

My partitions (that is, system, data and cache, not sdcard) are all ext4 (I converted them) so now I know, no superwipe needed. Thanks. And I know that I can flash mimicry 1.4.0 and do the rest of the installation (WifiCalling and efs-wipe from Aroma.) Excellent.

When I reboot into the bootloader, I see Vision, S-OFF, my h-boot version, radio, emmc etc. Then I see, in white on red background "fastboot USB," then instructions on using volume to go up and down, power to select...all as usual.

Then, my four choices...bootloader, reboot, reboot bootloader and power down...all as usual. I can move up and down as necessary.

Is that what I want to see? [Yes] The CyanogenMod Wiki says:

Some that is not very helpful...and probably a function of age. I didn't turn the device off, I just booted into the bootloader via 4ext. Any diff? [I think not.]

If I am already connected via USB and do this, I see no difference...so does it matter whether I attach USB before or after? [Can't see any.]

But most particularly, the instruction "Make sure the device is in FASTBOOT and not HBOOT" doesn't tell me how I'd know which I was in...it doesn't say "look for the words 'Fastboot USB' in red highlighting"...or something like that... "and you'll know you're in."

Question 1) Does it matter if where I have the blue highlighting when I begin to issue commands from the terminal? (It's initially "bootloader" that's highlighted.)

I can connect to my mac with USB, go "fastboot devices" and see my G2.

Next command is clearly:

flash (no partition needed, right? [WRONG]) PC10IMG.zip...but what is this zip...is it:

_this is the _main_ question_

VISION_RADIO_RCDATA_12.62.60.27_26.13.04.19 [this seems to be exactly what is needed...the radio is in this, and rcdata as well.]

or

VISION_RADIO_12.62.60.27_26.13.04.19 [didn't try it.]

in either case renamed to PC10IMG;

or must I do both, renaming them to PC10IMG in turn? Your answer says "fastboot flash the radio+rcdata imgs," but that doesn't make clear (to me, at least) if this is two files or just the combined one...do you see that "radio+rcdata" might mean two files or one that combines the radio and the rcdata in one? The two zips above are _almost_ identical in size...so close that it can hardly be a coincidence. This one, VISION_RADIO_RCDATA_12.62.60.27_26.13.04.19, is slightly bigger, and one could get the impression that it is the radio _plus_ the rcdata...EdKeys doesn't make clear how big that other file is. Yes, you do write "imgs" and not "img," which suggests two files...but still, if I understood what was what I could make it clearer, I think.

Whichever is the case, I then type:

flash [partition would seem to be needed...fastboot gave error otherwise] mimicry-1.4.0 (again, no partition need be named) [WRONG]

and then

fastboot reboot (right?) (never got here!)

So only three fastboot commands in all (after devices confirms that the phone is visible.)

Question: when do I get into Aroma...does that happen after I do fastboot reboot, or after "flash mimicry?? I have not used fastboot at all yet, so it's not clear. I'd like to try a different launcher (Apex instead of Nova, what do you use?) and of course I need to be able to tell it to load WifiCalling, now that I have the radio right.

Sorry I ask so many questions...as I said, I'd be willing to make a really watertight installer description if asked. The same goes for fixing the CyanogenModWiki...it's page on fastboot seems less clear than it could be...

If I have another PC10IMG file in my sdcard root (it's the original Froyo ROM) will it get in the way of this process (I suppose not, but just checking.) Shouldn't I leave that there more or less forever, as a desperation fallback boot alternative?

Thanks so much, and of course for Mimicry itself...a big improvement over the unrooted 2.3.4 I ran until yesterday

p-d

Next Day

I just went ahead and tried it, with ultimate success.

Could not get fastboot to work...so adb pushed the two zips (EdKeys new radio _plus_ RCDATA) renamed to PC10IMG and mimicry-1.4.0 over to /sdcard/, then rebooted into bootloader, which picked up the PC10IMG file and updated. Rebooted to bootloader to check on radio being in, which it was, then rebooted into recovery to run mimicry 1.4.0, and asked AROMA to make all the changes I wanted (add WifiCalling, test Apex, etc.)

All seems to be good now. I do wish that some benevolent intelligence was out there, making some of these things clearer...editing old instructions to reflect more recent changes, etc.

I cannot get fastboot to work right, though...would appreciate some instruction there. If I am flashing a radio, for instance, what partition does that go into...should I have said

fastboot flash system PC10IMG.zip ?!

that is the sort of risk I did not want to take, so I defaulted to the original instructions given by Joemm, when he posted the long list of radios.

Thanks to all, and of course to Blk_jack for Mimicry.
