CLOCKWORKMOD5 based recovery on Excel

[Charlie]

@ Mitre

What method did you use to backup the existing recovery?

Slightly off topic here, I just looked at the recovery.cpio file from the .zip and it seems that it is changing the id of the Excel (not 100% sure, as I cannot check against the original build.prop just yet)

Just wondering if this is causing some of the issues (you mentioned in another thread) with certain apps not showing in the market.

this version of clockworkMod was not made for the scroll so its possibly changing id but Excell shows up in market as unkownn scroll excell
as there is no mtd device on the excel i used the terminal to dump the nand blocs to the sdcard

Ah, I see. If you get time it would be great if you could add how you did this to you guide.

@ charlie
code

Code: Select all

cat /dev/block/nandf > mnt/extern_sd/recovery-dump.img

type this into terminal and you should get a dumped recovery image on the removable sd card BTW the sdcard on the excell is internal memory mnt/extern_sd is the TF card
i am pretty shure that nandf is the recovery ,img but to be shure dump all the nand blocks a to h to be safe i would keep them named as nanda nandb nandc etc
if you know the code to identfy the blocks i would be grateful

Update on what nand is what for helping with backup's before CWM5 flash.

From looking at this file init.sun4i.rc in /

nandc = system
nandd = data
nandg = cache

Still working on finding the rest out

@Mitre,

Have you ever done a factory wipe via CWM5 ? - if so did it change the build.prop

(I am still trying to understand the info in the Recovery.cpio file in the CWM5 install files - as it has build.prop info for an Allwinner tablet)

[Mitre]

i did a factory wype after installing CWMD5 from the recovery menu so yes that was straight after i installed it
the clockworkmod was made for Ainol novo7 advanced but is quite generic and is running on several tablets

Allwinner is the CPU same as we have in the Exel

ok thanks Mitre,

If you open up the recovery.cpio file (with, Notepad++) from the CWM install files, you can see what I mean, about the info at the top, and why I am confused.

See this file here : http://dl.dropbox.com/u/18307166/recovery.cpio

i see what you are saying but i think the recovery.cpio file is just the installer so it dont change the build.prop of your device probably as the ainol is similar to excel that is why this recovery works as we have the same cpu and board so the cwmrecovery got passed its a recovery not an image
once the recovery is on device then it is looking at the files on device to make a backup ??

Ok thanks, just trying to understand more about CWM5, I am getting there.

Have you restored from a backup you made with CWM5 on the Excel yet?
