Newbie question: How do I update CWM Recovery to 6.0.1.0?

[logjam]

Greetings all,

I have braved through updating my PMID702C to Jelly Bean, via William Kleiman's wonderful guide. It was a bit rough, but I slogged through it.

When I go into recovery mode (menu +power for several seconds), the version shown is
"CWMR Touch v5.5.0.4 Beta 15"

I have loaded the cwm_recovery_6.0.1.0_a10c_28072012.zip file on my SD card, and try to run it, but it aborts. Obviously, it's not the right version, but how do I uninstall/delete/replace it with the correct one? And, is 6.0.1.0 version the latest?

Many thanks one and all!

Some of this was covered a day or two ago. This posting has a link to CWM 6.0.1.2 along with info on which version to choose: http://www.freaktab.com/showthread.p...ll=1#post45094

As to installing it... At first I was going to say "you can't install recovery from recovery", but as I think about it, maybe you can. I'll have to try later when I get home. However, CWM is not packaged as an update zip, so you can't install it that way. Normally, you'd unzip the contents, copy it to an sdcard, then run the "install-recovery' script when your tablet is booted normally (not in CWM).

Yes, indeed, you can install a recovery image while in Recovery. I was already planning to release a group of CWMs for A13-based tablets but I thought they'd have to be installed the "old-fashioned" way using a script. Thanks to your posting, logjam, I now know we can make the process a lot easier.

Thanks very much Dolorespark! I have figured out how I could remove the two recovery scripts and the recovery image via ADB (as root user).

The question I have is, (newbie shield on ;-) how do I know if I have 9 or 10 partitions? I want to use the correct files for my 702c.

I look forward to your updated CWM files!

Thank you

how do I know if I have 9 or 10 partitions? I want to use the correct files for my 702c.

adb shell cat /proc/partitions

If the last one is 'nandi', you have 9; if it's 'nandj', you have 10. If you install the wrong version you won't be able to mount your internal SD card but everything else will still work,

BTW... I don't know if the 702c is an A10 or A13. Run adb shell cat /proc/cpuinfo to see if "Hardware" says 'sun4i' (A10) or 'sun5i' (A13). If the 702c is an A10, then the CWM you have should work without error (though I have no way of confirming this myself). If it's an A13, you'll get errors trying to install an update zip from your external SD card or trying to do a backup to it. In that case, you'll need an A13 version of CWM to get it to work right.

So far, so good...

adb shell cat /proc/partitions

If the last one is 'nandi', you have 9; if it's 'nandj', you have 10.

It's nandi

BTW... I don't know if the 702c is an A10 or A13. Run adb shell cat /proc/cpuinfo to see if "Hardware" says 'sun4i' (A10) or 'sun5i' (A13).

It's sun5i (A13)

So, will these be newer than the ones from William?
Finally, do I need to first remove the older version of CWMR via ADB, or just put the correct files on the SD card and install via Terminal Emulator on the device?

Thanks again. I'll shut up now

The 'recovery' program (aka CWM) will be the same but the kernel and 'init' binary will be from an A13 tablet.

The new version will overwrite the old one - no cleanup needed. If things work out as I expect (do they ever?), then you won't have to run any script, you'll install it like any other update zip.

I should be able to get those out tomorrow (Tuesday and Wednesday are my "weekend").

Awesome! I'll hold off until then.

Have a on me!

Another question

Somewhere in another thread, Finless Bob mentioned that the ext SD card can be partitioned so that one of the partitions is EXT4. Is this something that's recommended on these units?

I can't say if it's "recommended". I do know that it's required if you want to use Link2SD to move apps to your external card.

I just looked at 'vold.fstab' for both CM10 and my stock ROM, and they both make provisions for mounting the second partition. However, they give it preference over the first partition, and they have no provisions for mounting both. So, unless Linux is your OS of choice, you'll have to use your tab's USB storage option to move stuff between the card and your PC 'cause Windows won't see the 2nd partition & the tab won't see the 1st.
