there’s a plethora of cheap (~$50) refurbished ASUS MeMO Pad 7’s commonly available on sites like eBay, Woot, and DailySteals. though the screen leaves something to be desired, and it’s not particularly powerful, the MeMO Pad does have current entry-level hardware and a recent version of Android available. combine all that with easy-to-root status and you have a decent little secondary tab.
i found a lot of out-of-date instructions for rooting and conflicting info due to different versions of the MeMO Pads. the ME70C (shown as K01A in the About screen) is a slight step below the more common ME176CX. i’m not sure if these instructions work for the 176 series or not, but i’ve verified them twice on a ME70C.
standard disclaimer: anytime you hack around what the manufacturer intended, you risk messing something up. i didn’t create this exploit (shakalaca did) and bear no responsibility if you brick your device.
you may not need every step below, this is just what i did with a brand new tab and it worked consistently for me.
- settings > backup & reset > factory data reset > check “erase internal storage” > click the reset button and follow any additional prompts. (tablet will reboot)
- run through the basic setup after reboot, skip any account creation, DO join a wireless network and set the timezone. the tablet is probably then on android version 4.3 with build JSS15Q.WW_MeMO_Pad=10.32.1.33.3-20140916
- settings > about > system update > check updates.
- you should see a new update available, version 22.214.171.124.2, un-check “auto update”, then proceed with the update.
- when the update finished downloading, tap the notification to start the install and follow any prompts. (tablet will reboot to finish the install)
- the tablet should now be on android version 4.4.2, build KVT49L.WW_MeMO_Pad-126.96.36.199.2-2014-10-24
the root exploit
- download RootZenFone-188.8.131.52r.apk from here: http://23pin.logdown.com/posts/230216-root-rootzenfone-14r
- for the Android build number listed in step 6 above, you need RootZenFone version 184.108.40.206r! if you ended up with a newer build after the update, then you likely need a newer version of RootZenFone.
- if the above download link is not working, Google for the file and download from another source at your own risk.
- go into WiFi settings and “forget” EVERY network you ever connected to! then turn off WiFi & put the tablet into Airplane Mode.
- settings > security > check “unknown sources” & un-check “verify apps”.
- settings > about > software information > tap “build number” a bunch of times till you see the message “you are now a developer”.
- settings > developer options (verify ON) > check “USB Debugging” & check “Allow mock locations”.
- use the built-in File Manager app to find the RootZenFone-220.127.116.11r.apk file you downloaded and tap to install it.
- open the RootZenFone-18.104.22.168r app, tap OK to the disclaimer.
- get ready with one finger on the power button…
- tap the “OK I know, please root !” button and immediately start counting to 10 (one-one-thousand, two-one-thousand, etc.)…
- ignore any dialog about demo mode (i.e. you don’t need to tap OK or anything)…
- when you hit 10 (you were still counting right?) immediately turn off the tablet by holding down the power button and then tapping “Power Off” on the dialog that is shown.
- turn the tablet back on.
- after the typical ASUS boot logo, the device will go to an “android” logo for a moment. eventually it will restart again on its own and you will then see an “upgrading android” message briefly.
- once it’s finished booting up, you should find the SuperSU app in the App Drawer. verify it launches without issue and you should be rooted!
fixing any problems
if somehow you ended up stuck in “demo mode” – see these instructions for a fix: http://forum.xda-developers.com/showpost.php?p=57244888&postcount=7
if you just can’t get root – you likely didn’t wait exactly 10 seconds during step 7 above, or you have the wrong RootZenFone version for your Android build number.
