[GUIDE] Milestone XT720 - Apps2SD and Froyo JIT

[Navalynt]

Now there's a Russian ROM floating around, U2_03.20.1 ... anybody know anything about this one?

I am able to do follow the guide on my Singapore XT720. You have to flash your phone with the Euro Rom before using the v3 script.

So what would be the best way for me to flash my phone to the Euro rom and keeping all my contacts/apps/everything intact? And would I have to format my microSD again when I reinstall app2sd?

In the v3 script I added a line to delete any data from the ext3 partition prior to setting up the apps2sd so you shouldn't need to reformat if you already have your partitions setup correctly.

I personally use MyBackup Pro from the market ($4.99) to backup/restore my data. The only problem I find occasionally is that free protected market apps sometimes need to be uninstalled/reinstalled after.

I followed a guide on xda that said to use ext2 as the partition, would that cause a conflict?

any chances new V4 with the russian rom....if got v4 im flash to russian...
your V3 optimizer damn stable with tha new italy sbf....i very2 like it...

no more red blnking on battery....my temperature average 30 to 40..not more than that even running on hspda...

beako - You can use ext2 just fine but ext3 is preferred because it has journaling.

khalpowers - Glad to see it working out for you! I've never been able to get 720p recording to work with out some serious studdering but I did add an edit to the build.prop to double the max quality for 480p recording.

stukas - I got your PM and decided to give the /cache partition a try for the dalvik-cache. I have it booting but I would still consider the update below to be experimental.

So, here it, and experiment v4 of the script based on the Russian U2_03.20.1 flash. It booted without errors on my XT720 which was originally a 550Mhz clocked Singapore model and it is clocked factory at 720Mhz. I'm not sure what other optimizations have been done and I won't have time to run benchmarks until later tomorrow evening.

I also included an option to run my person cleanup script which removes some of the /system/app applications which I don't personally use. These are as follows:

• Facebook.apk
• MagicSmokeWallpapers.apk
• MotAccuWeatherWidget.apk
• MotoCAL.apk
• MotoCarDock.apk
• MotoGAL.apk
• MotoHome.apk
• Motonav.apk
• MotoNotePad.apk
• QuickOffice.apk
• VisualizationWallpapers.apk
• Email.apk
• MobidivKeyboard.apk

If you don't want these removed, don't run step 4! I have no use for these myself so they are just wasting resources.

Once I have some feedback that this is working correctly for others and that there are no issues with the dalvik-cache I will update the first post and maybe do a little more polishing on the script.

Wonderful Navalynt! Your work is really appreciated!

I just saw that there are US firmwares versione 04.1E.1

Differences?

At the moment I'm with the italian 02.1E.1 and battery is significantly better then before. The 3G radio does not become hot as before, even using heavily the data connection.

should we have symlink between both /cache and /data folder like this?

ln -s /cache/dalvik-cache /data/dalvik-cache

Using a symlink doesn't work for dalvik-cache, that's why it wouldn't boot up when you tried. You have to use mount --bind so I have that command running on boot-up instead of using a symlink.

Successfully installed apps2sd, jit and theme without error on my singapore xt720 with us firmware(it show STR_U2_03.20.1 on my device after v4 run? Before is STR_U2 04.1E.1).
Lipack avg... 8.24 (5 times run)
Quadrant Benchmark... 574 (5 times run)
Camera still got lines on screen( no more lines on italy rom and optmizer v3 ), may be because of v4 is special for russia rom and still on testing.
I am still not sure about battery consumption. Later i will update it.
BTW Mr Navalynt I really thank to you for your hard work for us. Thank!

Installed STR_U2 04.1E.1 with jit using v3 optimizer.
It shows STR_U2 02.1E.0 after jit.

Linpack around 8.3.
Camera (photo) seems much faster. I had to install APN for Italy since this version does not have them.
Looking for optimizer v5

I will report on battery tomorrow.

Yeah, each version was paired to a specific SBF file so it has the build.prop from that SBF. Therefore if you if you use v3 or v4 with the US SBF files that were recently posted it will be using the wrong build.prop.

Can make a version of optimizer for korean motoroi? It will be much appreciated. Thank you, you are a legend in this community.

XT720 OPTIMIZER V5 - US CBW U2_04.1E.1 BASE

*Edit: Updated the script to fix dalvik-cache (it was not moving to /cache correctly). Verified that apps are installing to ext3 partition and dalvik-cache is now installing to /cache partition.

All the usual, plus added what should be a working hacked version of Verizon's NFL application and some Star Wars live wallpapers (which I think I also had in a previous release).

In this release the cleanup script DOES NOT remove the MotoHome.apk so your default home/launcher is still there if you want to use it.
