[ROM] Sero 7 Pro (US/UK/AU/DE) - AOSP 4.4.4_r2 DoPa v2.7

Whatever crash you're seeing isn't the one that I fixed. That one was produced a full-blown hardware crash with a register dump. Your logcat doesn't show a register dump or even a Java runtime exception dump. There were two errors that caught my eye but I don't know if either would cause an "Unfortunately..." popup.

Here, the (software) communication link being used to download "Le onde" was broken. Later on, you got this error:

04-08 09:40:57.133 I/wpa_supplicant(  618): wlan0: CTRL-EVENT-DISCONNECTED bssid=00:1a:30:e4:64:00 reason=0

This download failure is a lot easier to understand: your WiFi connection had dropped. I don't know that either of these is something I can fix. As above, you may want to try the obvious fixes if you haven't done so already: use the most recent GApps package, clear the app's cache and data, and play with the app's caching options.

Clearing the cache & data seems to have fixed the issue. There must have been some issue carried over when I updated. Google Play Music works much better now. Before (on v0) it was laggy and sometimes unresponsive until it rebooted. Thanks for all your work!

@dolorespark hey, one tiny issue with v1. I tried to read a book in a cab on the way home and screen went dark. Looks like same issue reported to Dave about the auto brightness sensor dropping it too low at the bottom end and LCD goes black.

Otherwise rock solid!

Do you need extra hardware to cast screen? I was thinking as long as I connected to TV through wifi direct it would work but it still says no devices found.

Auto-brightness is not something I've touched. In fact, it's something I'd turn off immediately if it weren't already disabled - I'm deeply suspicious of stuff that tries to be "helpful" because it's usually anything but. That said, I enabled it, turned off the screen, then went into a dark room at night. When I turned the screen on, it was far too dim for my tastes but everything was also clearly visible.

Afterthought... I just checked and there is a configuration item which specifies the minimum brightness. Currently, it has the same value that was used for the Nexus7. I could increase it a bit, but it's not zero (which I assume equates to no backlight at all) so I don't believe that would fix whatever issue you encountered. Plus, others would probably complain that it's not as dim as it "should be". Honestly, I'd rather not mess with it if no one else reports problems.

Do you need extra hardware to cast screen? I was thinking as long as I connected to TV through wifi direct it would work but it still says no devices found.

No, assuming your TV explicitly supports WiFi Display. However, you do need to tap on the little menu thingy at the top of the WFD screen and enable it (now I see why the patch's author had another patch to change that easy-to-miss menu item to a nice, always visible on-off slider).

Tried to load the Asopv1 and got an error on
setting metadata, set_metadata_recursive: some changes failed
E: Error in /external_sd/sero7pro-asop442-dopa-v1.zip
(status 7)
Installation aborted.

Any ideas on what went wrong?

I had Xboxexperts rom installed, I went into recovery, wiped Dalvik and cache, install zip from ext SD. Then the error.

I thought I might have gotten a bad zip, so I downloaded it again and retried it, same error.

EDIT:
Ok, figured out that Exboxperts version of CWM does not work for this. I downloaded randomblame's version and and it installed, Now it is stuck on the android screen. I have waited 5 min and it is still stuck.

Edit 2
Ok, stupid me, I forgot to wipe the user data. Now it's up and running!!

Thanks for the work! Looks great!

 

[paratwa53]

I have been using it for a few hours now, and I have had no wifi drops or any other problems. I do not use the HDMI out or miracast, so I have no idea about those. Bluetooth with poweramp works great.

All in all I have to say you did one hell of a job getting this version up and running!

I am a bit concerned about power levels dropping faster than I am used to though. Any thoughts about how I can change my power usage?

 

[paratwa53]

There is defiantly a problem with charging. I left it turned off while on the charger for 7 hours, and its at 87% charge. Any ideas? It was at 56% when I plugged it in.

 

[kenundrem]

I am having no issues with charging or battery life. Everything seems really nice. Been using since last Monday. Thanks @dolorespark

Yeah I think it was the charger I was using. The charger I used last night is for my bluetooth headset, I guess it does not have the amperage to really charge the tablet.
I plugged it into its normal charger about an hour ago, and now it is at 97%. So I am guessing that was the problem.

I get freaked out easily when it comes to my tablet. It has become a very important device in my life. I listen to music on it while at work for 10 hours a day, and it is also my ebook reader. I don't use if for much of anything else, but music and reading are very important to me.
I don't even bother with my Kindle anymore since I got this.

FYI.....Even some phone chargers don't put out enough to charge the Sero 7 Pro and the LTE version. I ran into that problem and a friend bought a charger when his cord went bad, never got a full charge. Finally convinced him to just buy a new cord and use the Sero wall unit. Now it charges fine.

Question, I read that OTG is supposed to work with this version of ASOP, how do I enable it?

I tried hooking up an external drive, but my Sero does not see it.

I tried using the app USB OTG Checker, but it tells me "System Not detect USB OTG signal"

 

[Radon_22]

I plugged in my PS3 controller and it recognized it in about 30 seconds. It recognized my thumb drive right away.

You should try a different device. Then again, your problem may be with your OTG cable. Had it worked for you with another rom on your Sero?

It is a brand new cable. I have never tried using one before.

I was trying to connect to a USB hard drive, not a thumb drive. Maybe it is not in the correct format for Android. I have a thumb drive at work, I will try it again tomorrow.

Some OTG cables will not work on a device but will on another device. So if it doesn't work then try a different brand cable. I also use Nexus Media import/export from Play, used it before the Sero 7 Pro got support for OTG and it worked great.

The drive has to be formatted FAT32 or ext4 - this kernel doesn't support NTFS or exFAT. Also, does the hard drive have its own power supply? I'd be surprised if the tablet could supply enough power.

I am a bit concerned about power levels dropping faster than I am used to though. Any thoughts about how I can change my power usage?

When you wiped your /data partition, you deleted the system's battery stats which it uses to generate accurate battery usage info. You really shouldn't put too much faith in the battery readings until you've fully charged it then run it down almost all the way at least once. Once it has rebuilt its database, the readings will be more meaningful.

To prolong battery life, turn off NFC, GPS, Bluetooth and WiFi when you're not using them (GravityBox makes this pretty easy to do since there's a Quick Settings tile for each one). And of course, kill the screen whenever possible.

BTW... speaking of USB-OTG devices and charging the battery... Someone sent me a link to a kernel patch which enables you to charge the tablet while using OTG. Using it requires a special Y-cable so both the device and the charger can be attached, plus it may require a small app to turn the feature on and off. I'll add this the next time I build a new kernel.

 

[Radon_22]

This sounds fantastic - Being able to supply power while using USB could have a lot of applications. Know what cable should be used?

Did you mean LT? I would be shocked if there was an LTE Sero 7, and a Google search didn't pull anything up.
