Upgrading an early Asian A780

[irinoxx]

Hi,

I have this early chinese A780 (no GPS) I bought ages ago from ebay I'd like to upgrade to a less buggy firmware.
Current firmware version is :

R52_G_0D.37.A2P
R52_G_0D.27.B1P
GSOA780T672ZD013
6221A100
Quad-Band GSM

I've spent hours searching the forums looking for the correct firmware version to flash. It appears that the latest asian firmware is R52_G_0D.50.AHP_0D.42.B1P_T673AS_L001_S018_P003_GSOA780T673AS064_1ff.shx (correct me if I'm wrong)

Well, I'd like to know where this file can be downloaded from - the download section of this site only has the 76 firmware, and vllp.sourceforge.net is broken. Any idea?

Besides, before the upgrade I certainly need to backup my phone. Sadly DumpFW (http://www.motorolafans.com/forums/attachment.php?attachmentid=851&d=1141927886)
Doesn't work properly on my phone, leaving me with a broken unusable 3.8Mo firmware.dmp file.

I took a peek at my phone's /proc/mtd and it seems different from what other people have on this forum. Could it be the issue ?

dev: size erasesize name
mtd0: 00020000 00008000 "Bootloader"
mtd1: 000e0000 00020000 "Kernel"
mtd2: 00580000 00020000 "VFM_Filesystem"
mtd3: 00020000 00020000 "Logo"

Could someone give me an idea on how to backup my current firmware?

Thanks a lot

at least at the firmware i can give you a hint:
ftp://ftp.planetmirror.com/disks/1/s...KF063_full.rar
but on the rest i have no idea

Hello,

i think it is the best to find the same firmware file which you want to backup, so no backup is needed.

If motodump not working with your phone try flashkit (only some parts will be saved).

And maybe with your saved CG and a monsterpack with same bootloader you could give it a try to bild your own Firmware.
Have a look at EZXCodec.

I never tried this but maybe there is a way....

This is great, thanks. As I've been away from motorolafans for a long time, I'm still catching up on everything that has been discovered and created here...

Sure that would be great, but really firmwares are so hard to find and my phone version is so old I think it won't be possible.
Look above, I was looking for some firmware reference, and the one I got looks good, but already slightly different. But maybe all these _Snnn_Lnnn_Pnnn_thingamagic numbers are not meaningful, I don't know.

Well I managed to dump and save diska and transflash, but clearly that's not enough. I'm going to look into flashkit and see if it can be of any help in my case.

Now you've totally lost me

Hi,

so i had a look at this EZXCodec and it seems it is not for the A780.

The firmware is classify in different code groups some can be copied other you can get with the flashkit.

Information about the code groups
http://wiki.openezx.org/EZX_Platform_Overview

Flashkit
http://www.motorolafans.com/forums/v...56acc460f2215a

With flashkit these parts are modifiable.

mtd4: 000e0000 00020000 "R/W Kernel (CG32)
mtd5: 018e0000 00020000 "R/W RootFS (CG33)
mtd6: 00020000 00020000 "R/W Setup" (CG36)
mtd7: 00020000 00020000 "R/W Logo" (CG37)

This you can copy and maybe also some other parts dont know
cp /dev/tffsa /mmc/mmca1/cg35.smg

be sure to copy /.system on booth

if you want to backup your user data you can do this:

Create a shellscript with the following content:
#! /bin/sh
tar -cf /mmc/mmca1/ezxlocal.tar /ezxlocal
tar -cf /mmc/mmca1/email.tar /diska/.system/email
tar -cf /mmc/mmca1/mms.tar /diska/.system/mms
tar -cf /mmc/mmca1/home.tar /home
tar -cf /mmc/mmca1/PlugCardDB.tar mmc/mmca1/.system/java/PlugCardDB

i dont know if it is possible to restore them after the flash
(i dont have an asian one)
i have done this with a flash from .74 to .76 and most things have worked.
but i think it is worth a try

cp /dev/tffsa /mmc/mmca1/cg35.smg

if i remember correct there was something with diskdump:
dd if=/dev/tffsa of=/mmc/mmca1/tffsa.img

[Halftux]

yes you are right swifty "dd" work as well and should be used with other cg's in cyph's miniroot.

I have found some other dumper from cyph maybe it is useful.
You can also change the sources and get a full dump tool.

cyph:"It basically reads /dev/mem which is a device representing the machine's physical memory."

[swifty]

ah, yes!
cyph is missing here long time.
he found a second life outside of motofans.
there is much old knowledge, not only from him, in this great forum here

nice to see someone digging in the deep "old days"
