[How to] Make a copy of your OTA update file (for backup/testing purposes)

[drock212]

Hi Everyone,

It was brought to my attention that there really isn't a clear explanation anywhere (as far as I know) on how to capture an OTA update file once you've downloaded it (for backup and/or testing purposes of course). So I've decided to write up this brief and simple "How to guide".

1. You need a rooted device
2. You'll need to download and install root explorer or Super Manager
3. Go ahead and download the OTA update BUT once downloaded DO NOT INSTALL yet, hit your back button or simply tap install later.
4. Open root explorer and navigate to the folder that says cache.
5. You'll see the OTA update file in there tap and hold then select copy.
6. Paste file to your external sd card (from there you'll be able to move it to your PC or where ever.
7. Since you have now successfully made a copy of your update (purley for backup purposes of course) navigate to your settings>about phone>system update and this will bring back the option to install the update

Any questions or suggestions I would be more than willing to answer or make edits to the OP if anyone sees a step I skipped or missed

Thanks to DarkRyoushii for the idea
Thanks dLo GSR for the super manager suggestion

Thanks! If I see an OTA message popup anytime soon I'll make sure to back it up before installing..

Hopefully that user with the dev device that received a 1.75 update (claims) hspa is enabled can push that update out to all of us...

he won't, he said he's said too much already :/

For those too cheap to buy root explorer, this can be done using ADB as well, right?
Might be good to post up instructions using that too

Smells like BS then..if he said too much he would have known what was going on with his device....

cool, i heard a new prerelease update should come

if you don't want to buy root explorer, Super Manager is a good free app as well.

So it just like nandroid ?
Its a full back up of the system? (ghost?)
Its only make a backup of the update? no backup of the system?

Edit:
OH, its backup the Update that available.
but how do i make a nandroid ? without a recovery..

 

[DarkRyoushii]

step 1. get a recovery.
step 2. make nandroid.

:3

I'm sorry that was mean, I honestly don't know if its possible without a recovery though :S

Ok, I receive the 1.75 message and did the steps. There were two files in the cache folder and I copy the most recent one. I hope it is what we are looking for.

DID YOU SIGN UP FOR THE BETA?! If yes, please remove it and respect the NDA that you agreed too. We are trying to set a good example at xda by respecting motorola, regardless if it helps us get a bootloader solution earlier. :/

If you didn't sign up and just got the update randomly.. I'm amazed XD

what area do you live in, where you running .26 or .57, did the update pop up or did you check for it manually? Also I don't believe that to be the update. They're usually zip files and the .57 update was around 17mb... weird if that was your only file

 

[DarkRyoushii]

he said that there was 2 files but he only grabbed the latest one.. so I'm assuming he only picked up the market.apk (probably from a market update) instead of the .zip

I live in Mexico. I have an unlocked Atrix. I need to be rooted because I use the hotspot app a lot. I didn't sign up any beta or NDA. I just received an OTA message to update to 1.75 two or three days ago. I haven't do that until I'm sure I can continue rooted. If there is anything else I can try please let me know. The other file is not too much different of this one.

as previously mentioned in another thread, press okay and let it download, it will then say install now or install later. YOU MUST CLICK INSTALL LATER. then you can goto the cache file and just incase you get the wrong thing, copy EVERYTHING from the cache folder like instructed in the OP of this thread.
