[ROM+Kernel] MiRaGe-CM7.2-IHO (07132013)

[stayplation]

... I've unzipped, added & deleted files (i.e., unused/outdated system apps, custom scripts, and ringtone audio) and re-zipped on every MiRaGe update that I have flashed without any issue for over a year now. I do this with 7-zip on Windows platforms. I haven't encounter any issue with checksums, hashes, permissions or whatever unknown reasons with the modified zip file.

This is good info, thanks. I still don't know what the files are in /data/system/dropbox. Someone must know around here.

I have had no problems extracting, changing (deleting/adding system files including the framework.apk), then zipping,signing,creating md5 sum-all from phone.
I have Root Explorer.zip signer, and AFV (Android File Verifier).

zipping what? The entire ROM? What are you signing? The apk? I will look up what rootexplorer and afv are maybe that will fill in the blanks for me.

-all from phone.

Okay I get it now, you do this all from the phone, you're not re-flashing the ROM. Right?

I have done this many times in past when trying to find the right combo of host ROM, ported ROM, and kernel. I used the computer only to edit the framework.apk files.
After each combo I would zip and flash to my phone to see If everything worked.
Took me a week to find the right combo. I then signed the zip and generated an md5 sum so it could be downloaded by others.
No interest in the ROM anymore so I deleted it from download site,computer, and phone.
I did everything from phone (except the framework.apk) including editing the build prop.

Okay then, I must be totally wrong. I admit it. I'll stop passing along that misinformation. I do however wonder what advantage is gained by unzipping the files? I find them just as easy to work on inside the .zip as they would be extracted, so am I missing something here?

The details really help, thanks. There're so many different ways to do this stuff.
Much obliged.

You're working on unzipped copies but maybe the software you use makes it seem that you're not. But, because zipping a file compresses the file's data, to work on a zipped file it has to be uncompressed first. I didn't know what you meant at first.

I unzip, edit the files as needed, re-zip and re-flash just so that my phone matches what I have on the laptop and vice-versa. I think it is just a matter of preference.
The main thing for me was to know that unzipping, editing, re-zipping, re-flashing wouldn't make break things. How anyone goes about it shouldn't matter.

I have an LG Optimus U (LG-US670) and installed this ROM... it works great!

Note that I don't use the cellular capabilities of this phone so I have no way to test that part. I only use this phone for when I jog or do other exercise stuff. Bluetooth heart rate monitor and BT headphones work great, WiFi works great, GPS works great, etc.

And unlike the stock ROM this one lets me turn on BT and WiFi when in Airplane mode. Before I could never use Airplane mode with bluetooth.... so the unused cellular radio was draining the battery unnecessarily.

I'm very pleased....great job guys

There seems to be an issue with excessive battery drain when Bluetooth radio is enabled (even if nothing is connected to it). My phone will drain almost completely in about 16 hours. If I disable the BT radio then the battery will only drain a few percent in that same amount of time.

Any suggestions?

Even though there's no connected BT device, the BT radio is still active which it will continuously try to search and acquire for connecting device--draining battery. Battery drain can be minimized only by disabling BT when not in use.

Of course... I understand that when BT is enabled there will be some power usage there. But my point is that the battery drain is INSANE compared to the stock ROM. I had always left BT enabled with the stock ROM and the battery drain was pretty low. Now my phone is dead within 16 hours of just sitting on my dresser not being used. If I disable BT there is a HUGE difference. Something is wrong somehwere...

Looks like it might be an issue with the official CM7.2 on some hardware. Here is a guy talking about it with a different model Optimus:

CM7 bluetooth stack for Optimus One/p500/p509 is a battery drainer | mindful omnivore

Google msm_serial_hs_dma wakelock shows a lot of additional info. Basically if BT is enabled the phone will NEVER go into sleep mode, leading to excessive battery consumption.

Never really noticed stock ROM behaviour as I've been using CM7-based ROMs for quite some time now. I also use BT only while driving so the phone is always plugged into the auto adapter when in the vehicle. And I disable BT all other times when not in use. Battery life of 16-hours with BT-enabled seemed fairly typical to me... I didn't realize there is an issue?

Keep in mind that this is 16 hours while the phone is supposed to be in standby. No usage other than occasional normal background tasks! As I mentioned in my earlier post I rarely use this phone.. I only use it when exercising. So it normally just sits there. With the stock ROM it would go for 4-5 days between recharges but now its dead in 16 hours. Definitely some issue with the BT driver.

It appears there is a fix for it (I saw the patch posted on github somewhere). If someone is still working on this ROM it would be awesome if that fix could be incorporated.

Wow MRG. You have my Optimus V back up and running, again.

It's been unflashed for months and I've decided to get it up and running again.

I'm seeing this problem as well. With Bluetooth enabled, my battery is constantly warm to the touch, and drains within 6-8 hours.

I don't know if it's related, but I started seeing this after the upgrade to the 07132013 ROM. Is anyone experiencing this problem using a previous ROM?

For now, I manually turn off Bluetooth when I'm not in my car and won't be using it.

Hey guys, after installing this ROM I'm having a hell of a time with the Google Play store. 90% of the apps I try to install or update give me the "invalid package file" error. I don't have this problem on my other Android devices so I don't think it's related to the recent issue that Google had with the Play store.

Any thoughts? What might be causing this?
