After learning a lot through trial and error, messing with several D2 Roms, I came up with this handy "tool" that I've been using it to test ROMs. After flashing the D2 Rom of your choice, flash this update to "convert" it for use on the Global. This tool allows any D2 Rom to be run on the D2G (don't quote me on that, I haven't personally tried them all, but so far every one has worked). Before trying this out, please become familiar with the known issues. Obviously use this tool at your own risk, neither I, nor any other member of Get~R~Done are respondible should you brick your phone. If this is your first time installing, download one of the following two files to the root of your sdcard along with a D2 rom of your choosing. If your installing Liberty 1.5 or Fission 2.5.7 download this file: D2G_Romer_v7.zip For Squidly and Apex 1.3.1 use this file: D2G_Romer.zip (bluetooth and global data will not function, see known issues as Apex has some other issues as well) Links to all previous versions of the D2G_Romer are in the changelogs. In addition to the Romer, you will probably want to download the following, to quickly/easily enable/disable the sensors: D2G_Sensors.zip Installation Instructions 1. Reboot into Clockwork Recovery 2. Create a nandroid Backup 3. Factory Reset/Wipe Data/Cache 4. Choose install zip from sdcard and navigate to the D2 Rom that you downloaded earlier. 5. As soon as that completes, choose install zip from sdcard again and flash the D2G_Romer.zip 6. (Optional) As soon as the Romer Flashes, choose install zip from sdcard again and flash the D2G_Sensors.zip (to disable the sensors, see known issues for more details regarding the sensors) 7. When done, reboot your phone, hopefully, if all went well, you will not bootloop. For Liberty and Fission only, If you have already flashed a previous version of the D2G_Romer.zip just download the most recent version above and do the following: 1. Reboot into Clockwork Recovery 2. Choose install zip from sdcard and flash the most recent D2G_Romer.zip (FYI, there is no reason to flash the Sensor.zip as they are automatically disabled starting in Romer_v5) 3. When done, reboot your phone. Known Issues 1. All of the sensors are functional when enabled. Unfortunately they somehow cause the phone to soft reset whenever it sleeps. Because of this, they are disabled by default in all versions starting with version 5. The D2G_Sensors.zip is essentially a toggle. If sensors are working (and your phone is rebooting everytime it tries to sleep), flash D2G_Sensors.zip to disable them. If your sensors arent working (no auto rotate, and your phone will sleep like normal) flash it to enable them (and help me figure out what the problem is). 2. build.prop will not report your rom as whatever you've flashed. It will say it is D2G Rom-er. This is because the tool is generic. I really didn't feel like making a seperate tool for every D2 Rom just so build.prop will report correctly. This easily fixed by manually editing build.prop from root explorer. 3. For some very strange reason, I can't seem to get a dialer in apeX 1.3.1, and others have had bootloop with 1.4 (requiring SBF). I got 1.4 to boot on Romer_v1, still no Phone app (it is in /system/app, but doesn't show up in the drawer) 4. [Fixed] Bluetooth was broken, but was fixed with v3, unfortunately v3 broke some scripts for those of you trying Liberty. This was fixed with v4. There are other problems starting bluetooth for those that never got the OTA update. This is easily solved by downloading the complete 2.4.330 Rom from this thread HERE. 5. There have been reports of "M" logo bootloop with Squidly on Romer_v5. General Warnings Please familiarize yourself with SBF before trying one of these. I flashed a rom that would not let me boot back into Clockwork recovery (gummyjar - I should note that Liberty, which is based on gummyjar, works just fine). As of now, I don't know how/why that would happen so be careful, and do not do this unless you are comfortable using the SBF released by TBH. Before you flash any rom, be certain that it doesn't include the D2 kernel or Radio files (I'm not aware of any that do except maderstock and that's for the X). A D2 kernel on the D2G could mean a brick, and not the SBF cureable kind. For those that are wondering, this does not work for D1 Roms Changelog Version 1 is the only version safe on most D2 Roms. The other versions are safe with Liberty1.0 and 1.5 only. v1 Released 2-11-2011 v2 Not released v3 Released 2-12-2011 - Fixed bluetooth and Global Data, but broke Liberty custom scripts v4 Released 2-13-2011 - Fixed Custom preinstall scripts. v5 Released 2-13-2011 - Slightly smaller file size, automatically disables sensors, fixes some obscure adbd issues. v6 Released 2-16-2011 - Minimized duplicate files to reduce download size, no need to upgrade from v5. v7 Released 3-15-2011 Fixed Lights (soft key and keyboard lights now on for 15 sec after last touch) Thanks to baker1md for the commands! FAQ's Q: Is D2G Romer a custom rom? A: Not really, it is packaged like one but essentially just copies factory D2G files over the wrong D2 files. You could flash a D2 Rom and adb push and permission the files, this is just MUCH faster and easier. Q: Really, I can just flash this over a D2 Rom on my D2G and finally mess around with my Global? A: Yep, it does have it's quirks (namely the sensors), but I think it gets us closer to more full roms on the D2G. Q: If I already used a previous version of the Romer, do I need to wipe data/cache when I update Romer? A: Shouldn't have to if all you are doing is updating the D2G Romer, just reboot into recovery and flash the newer version. If on the other hand you want to flash a different D2 Rom (or update the underlying D2 Rom) you should definitely wipe data/cache.
