After waisting hours trying to root and downgrade my DHD using Win7 and being told that "the main version was too old" or some crap like that, I desided to go for the Linux way. And as it turns out, Linux saves the day (as I would expect :) )!
- Download aahk AND READ THE MANUAL!
- Download Ubuntu 10.04 Live (because that's what the 'efffen manual' says (from the aahk kit))!
- Open Terminal and type: wget http://tau.shadowchild.nl/files/aahk-12062012.zip && unzip aahk-12062012.zip && sudo ./hack-ace.sh (12062012 was the current version. Use whatever is the most recent). TIP: By default this unpacks aahk to the user-folder.
- Open CAJUN.txt in the /tools/txt/ folder and paste the content into Terminal and proceed (use the 'cat' command to display the text file if you want)
- If PD98IMG.zip is invalid aahk will download an alternate version (PD98IMG-GB2.zip). Mine did and worked through Linux and not Win7
- If things worked, you should now have a downgrade phone. Turn off 'fast boot'!
- On the phone enter Recovery mode (doing the 'volume down'/'power button' thing)
- Whipe ALL DATA on the phone (whipe data/factory reset and whipe partition cache)! My MIUI rom got stock in boot screen because I forgot to do that!
- Navigate to the locationen where you put your ROM install zip (from sd-flash) and let it do its thing
- If it works you should now have a DHD with Android v4.x.x
- If things fail READ THE EFFFEN MANUAL! :)
Notes:
- To avoid Chinese gibberish, install an earlier English version and then MIUI 2.8.24 without wiping anything. This preserves data.
- By default bluetooth doesn't work for MIUI 2.8.24. Install KangBang Kernel.
