With the release of the Android 4.3 Sense 5 update for the HTC EVO 4G LTE, the internal data map of the device changed drastically. Whereas once you were limited to a partition with a couple of gigabytes for your apps, now you’ve got access to most of the phone’s storage. The upside is no more out of space issues, but the downside is the new partition mapping makes old ROMs not function.
There are ways to make the old ROMs function if you’re S-OFF. You can install an old RUU, which takes you back to the old partition map and firmware and then install the ROM, but you’ll lose out on the radios and the goodness that is the new partition layout.
Fortunately, at a few days post update, several AOSP ROMs have been updated to work on the EVO 4G LTE with the new layout, and Captain_Throwback, the developer who brought us the rooted Android 4.3 update, is keeping a running list over on XDA of what these are.
The quick cheat sheet version currently posted include:
- CyanogenMod 11 as of 20140219
- Omni ROM (at least this download)
- Beanstalk KitKat (which supports both new and old layout in separate downloads)
…with more probably coming soon enough, since a partition layout change is not a particularly insurmountable obstacle to most developers.
Hopefully with this new layout, we’re going to see some renewed development on the device that could have, and should have, but didn’t due to HTC’s abysmal original partition layout. It will be interesting to see if the new firmware and radios cause the same problems to the AOSP ROMs that they were causing with the Jelly Bean ROMs, or if the data problems are finally gone after a year of seemingly unfixable spotty data.
You can check Captain_Throwback’s thread (source link below) for updated AOSP ROMs as they’re announced or become available, although be aware that isn’t a support thread, nor a beg a developer to make a ROM work thread. Just an announcement location.
