That's probably why my Sero seems agonizingly slow. However it only happens if it's been running for over a day. Upon restarting it's reasonably snappy. I'm not sure if I used Google's backup & restore method but I did use Helium to backup and restore.

I've been tempted to do a full wipe & re-install all the apps manually. It's not much work, just takes time. I'll report back with the results later.

volume keys in the navigation bar:

I used to add them OCCASIONALLY in my ainol Venus, using the build.prop.

It doesn't always work. AND you should never play around in the build.prop without backing it up and you must have a Nandroid.

this is what I used, AND I HAVE NO IDEA IF IT WILL WORK IN THE SERO. NEVER BOTHERED TO TRY IT.

must have root.

must have edit/write turned on (r/w function in your file manager)

open system/build.prop

find and edit OR ADD (if not present) the following lines:

ro.systemui.volumekey=enable (disable to remove)

save. reboot.

OR the app Virtual button bar works in the Sero. It's a stand alone app, not part of xposed installer/framework. It places volume buttons on the screen. You can move them around where ever you would like them. Change their color too.

I'm curious about how this works for you in your car. I installed a touchscreen stereo system in my mustang. It works well, but I can hardly see the screen during the day! Which really makes me pretty mad. And I wear polarized sunglasses which makes it virtually impossible to see. But I BT from my phone most of the time, so I can control what's going on, as I can see with my phone's display. I might want to do this with my Sero. So, will your speakers be BT? or what? Just wondering how this all works? I had to do considerable wiring when I installed the touchscreen, it wasn't fun, lol. I might not want to do that again... just say'n.

I really haven't satisfied my curiosity yet on this backup from google issue.

If you don't choose "setup as a new device" and choose a backup from google, you get "can't restore from backup" "try again. Skip". Choose skip and it installs the backup that doesn't work properly.

Initially I was only offered a backup from my phone and my Vidaa tablet. But, I have 6 devices backup to google. The phone and the Vidaa I use everyday.

The sero I use for a media device and sometimes isn't hooked up to wifi for long periods of time. The others I don't use much. SO, my thinking was because the other devices weren't recently used, I wasn't offered the backup to use. There's a little pull down next to the device that's offered, where you can choose another. So I have been using only the Sero, and my phone, the past several days. In theory, this should show google that I'm using the device regularly and offer it. So I reflashed the ROM this morning, and after a full wipe, still google doesn't offer me the choice for the Sero. wth, google!? So, I'm still baffled on how it chooses.

I'm not done with it, lol... I'll figure it out.... maybe.:mad:

Another issue I see, wondering if anyone else has it.

during the setup, after entering my network password, I get the "checking connection" screen where it just keeps checking.. forever. then finally it says "taking too long? Try going back and connecting to a different network". When you go back, it shows you connected. Then you can choose 'skip' as you really are connected, and just move on.

I also had it "Checking connection" forever, but I think it worked eventually...

Thanks, I'll give that hack a try.

Update: Doesn't do anything. Also no bricking so a good enough outcome for me :)

Regarding the car install, this is a very common setup, though it's usually done with a Nexus 7. Here's one thread with a lot of details: http://xdaforums.com/showthread.php?t=2103183

TL;DR is that the tablet goes instead of the head unit into the dash (semi-permanent install) and you power it through a OTG Y-cable. Then connect the amp either to the 3.5mm jack, or connect the tablet to a USB hub into which you plug in a USB sound card, which you in turn connect to the amp. You can also plug whatever you want into the USB hub - DVB tuner for radio/TV, webcams, storage, xBox controller dongle, etc.

Of course it involves a lot of DIY with a bunch of Chinese parts off ebay, but the results usually work quite well even in a convertible like Miata that I have. What does suck now that you mention it, is the polarization issue. I wear polarized aviators and just checked that, of course, the tablet's screen is polarized such that it goes invisible in horizontal mode :(
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Didn't think so... In any case, wouldn't those buttons be small and inconvenient to access when driving? It sounds like you need an appropriately sized widget for media control.

I have yet to see a single person in North America mention a DVB TV tuner. They seem popular enough in Europe but not here - do they even make an ATSC version? (It may be like cellular modem dongles: they seem to be popular in east Asia but are unheard of here.)

While researching something else, I ran into a couple of build.prop entries that tell Google's SetupWizard not to worry about whether there's an internet connection. With any luck, that will work around this problem, and perhaps avoid the crash you get if you fail to provide your Google login ID. I'll be testing this shortly because...

Android v5.1.0_r5 was released yesterday(?) and I've just finished building it. It gives me an excuse to try out something new and/or very old on y'all: ODEXing.

Prior to Lollipop, an odex file was just an optimized version of the Java byte code that still had to be interpreted at runtime. Now odexing involves compiling the Java code into an executable that can be run directly by the CPU. If it isn't done beforehand, the compilation occurs the first time you boot up the device - which is why the first boot takes so long.

To speed things up somewhat, the ART compiler skips stuff that would take too long so you end up with a mix of compiled and interpreted code. However, there's a flag that I've used that tells it to compile

everything

. This should produce at least a marginal improvement in speed.

I've also set this flag for apps that you download (including the Gapps you install along with the ROM). This means that apps will take longer to install but should run faster. Consequently, initial boot is only speeded up by about a minute because ART is doing more work on the Gapps than it used to.

There's one final win-some/lose-some aspect to this: because the ROM's odex files stay on your /system partition, it frees up about 30mb on your /data partition that you can put to better use (the odex files for Gapps and other downloaded apks continue to use /data). Conversely, there's 30mb less free space on /system, so if you install a jumbo Gapps package, you may run out of room (especially if /system is formated with F2FS).

I'll release a beta of this "shortly"...

Am I the only one experiencing battery drain by "miscellaneous"?

I've read about that only on nexus 5 devices, and supposedly it has been fixed with 5.1. After switching off "scanning always available" in advanced WiFi options and turning off WiFi it might be better, I couldn't fully try that out yet. I've got a refurbished sero, so maybe the battery's a bit faulty.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kc12:
my two biggest drains are the screen - even with the screen brightness turned all the way down - and Misc. 36% and 26%.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ratyfu:
Well, after turning off wifi miscellaneous disappeared from battery stats.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kc12:
I already have network notifications and scanning always off. Neither one of those affected the miscellaneous . But i just now noticed the battery saver option. I turned that on.

You turned wifi off completely?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ratyfu:
Yes I did, in order to see if it's the pre 5.1 bug that nexus 5 owners were talking about. Also, I wanted to make sure it wasn't my battery that was dying of old age.

Anyway, turning WiFi off didn't solve it. Turning both WiFi and scanning always available off did, though. Now I'm gonna test WiFi on and scanning always available off. Will report back soon ;)

AOSP 5.1.0_r5 - DoPa5 v1.2 beta0

For the flashaholics, I've posted a new beta.

The major difference between this ROM and previous versions is that it is ODEXed. This may provide some improvement in performance and usable storage but will slightly reduce available space in your /system partition. It also includes some 'build.prop' settings that may help tame the Google SetupWizard.

Installation instructions are the same as in the O.P.

sero7pro-aosp510-beta0-v1.2.zip the full ROM

sero7pro-nexus7spoof-beta0-v1.2.zip identify tablet as a Nexus7 to (possibly) show more apps in PlayStore

sero7pro-philz6.58.0-dopa-v2.7.zip a customized version of Philz Touch CWM-based Recovery v6.58.0 usable on all versions of the Sero 7 Pro

Looking good so far

AnTuTu shows - 20892 - hope that is in line of expected - do have an item where google play services hourly eating a small bit of battery - but disabling fixed that (trying to halt with firewall now just for ease of enable)

Keep up the good work - You ROCK

Finally did a fresh install of the latest beta without using Google's restore or 3rd party restore. Everything seems snappy. Some apps take a little bit to open but it's nowhere near as laggy as before. It's probably best to recommend a full clean install to anyone wanting to get the most out of this ROM.

recovery

I cannot get philz v6.58 to do a recovery of either dopa2.6 or AOSP 5.1. Keep getting "Error while restoring /data" . In the other 2.6 thread this came up and recovery was accomplished use the older philz v6.56. Does anyone have a link to this philz v6.56 version? FYI I can recover an older (1/26/2015) backup but not any made after. I think all the others were backed up using v6.58.

When you state "third party restore," do you mean using something like titanium to restore apps?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] natenkiki2004:
Yes, Titanium, Helium, etc. I was using Helium but I think it causes the same issue as Google Restore.

At startup....

Been using DoPa5 v1.1 and now DoPa 5 v.1.2 beta.... but I start getting this error at startup: "Process system ins't responding. Do you want to close it?". I'm not sure what to do.... just close it and ignore? Having this error prompts me to to go back to DoPa 2.6 but then thats where I find I cannot just recover 2.6 or any other using Philz touch 6.58. I have to do a new clean install everytime. Not really a problem per se but a pain. I'm more concern with Philz recovery though. Anyone else actually try recovering a backup lately?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Sorry to hear you're having problems. Others have reported the "Process system isn't responding" error but I never see it. I'd need a logcat to work on it (or a way to reproduce the problem).

As to older PhilZ, here's all of them - I'd suggest v2.51 if you have the US model:

sero7pro-philz6.56.2-dopa-v2.51.zip - US

update....

First... thank you for posting all those past Philz recoveries. Let me tell you where I'm at. Some back ground first: The oldest backup I have is from 1/29/15. After that I have several starting around 3/19/15 up to today. My oldest (1/29/15) will restore but none of the others. Today I tried ALL of the Philz recoveries that were just posted. None worked in the restore of any except the one dated 1/29/15. After restoring this older... I immediately back it up using the latest Philz 6.58 v2.7. Went back wiped clean, and restored this backup. It worked well. NOW.... because this was a backup of a backup and was dated 1/29 Google went through and did its updates. After everything was done and cleaned up I made a backup of this current system. I went back to RECOVERY, wiped the system and tried to restore this current backup..................FAIL. Just as before it failed at the restoring /data. This is starting to make me think Google Play has something to do with this. I'm kinda stumped right now. FYI my sero7 is US version and NOT refurbished. Thoughts?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Yes, two:

* Philz lets you select the partitions you want to restore. Try restoring just data; if that works, restore boot and system - the rest don't count.

* mount your SDcard on a PC, then look for the ClockwordMod/backup(?) directory (I'm at work, so this is from memory). In that tree you should find all your backups. Try opening some of the data partition backups using something that can handle *.tar.gz. Are you able to access the files and directories in the archive or do you get an error?

It used to be that PhilZ/CWM created 2 files for each backup, one with a 0 length and the other with a '.a' extension that was the full backup. If needed, remove the '.a' to get Win to recognize it.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] alanmv567:
Awesome rom everything works so far for me. Every time I reboot the tablet it starts optimizing the apps again. Does everyone else get that also? It's the part where you first start the tablet brand new or clear the kernel it has to load all the apps again before it goes to the lock screen.

Proper backup and Sdcard? (8gb US model w 32gb microsd)

Love the info here, thanks everyone for sharing. Had some questions that have been eating up my time, hoping you all can help. 90% of my trouble seems to be how to configure my sdcard going in.

I have ClockworkMod Recovery, but not sure I have Philz, anyway I can confirm this? Or should I just install from zip file the attached philz via ClockworkMod recovery screen?

Before I flash to this ROM, what format should I set my 32gb micro-sdcard to? exfat / ext2 / ntfs? Do I need 2 partitions? I tried a few via aParted, but seemed to not improve the situation. OS either didn't recognize / allow me to mount / wouldn't let me write to card during backups. Would you advise formatting within Windows and with what specs / formatting util?

I ask due to issues while generating a backup to my ext sdcard when going through ClockworkMod's recovery screen, could make local backup but not on ext sdcard. I've heard that if not saved to external it will blow away my stock backup locally when flashing to new ROM. Otherwise anyone know where my backup maybe located locally? I don't remember seeing it under the Clockwork dir for backups as another user stated, even though it built one.

Any input is much appreciated!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] richslocum:
I tried to just restore /data....FAIL

Looked into each of the backups. I can open each of their cache.ext4.tar AND system.ext4.tar BUT cannot open data.ext4.tar files. Cache and system opens and I can see all the "stuff". Data "opens" but appears as nothing is there. A couple of the backups also has a recovery log file but not all of them.

When I tried using Philz 6.52 (backing up then recovering the same ) I did see the '.a' AND '.b' extensions. I'm checking all this on 11 different backups.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] natenkiki2004:
Unfortunately the sluggishness in my tablet came back, even after a totally clean install without using any backups. Opening some apps like YouTube, Google Music and some others can take forever. Sometimes trying to close them or wake with them running, it's almost impossible. It becomes so unresponsive that it's faster and easier just to shut it off and reboot.

Well, playing around yesterday and today, I think I found a big issue; the Google Now Launcher. I don't know if anyone else has it installed but I removed it on mine yesterday and I haven't seen my tablet this snappy since Kitkat, maybe even before. Has anyone else experienced this?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] tinybeetle:
Yup, experienced the same thing. I installed Apex instead and BOOM my Sero works great again. I think part of the issue may be that the Google Launcher is always running waiting for voice input "OK Google".

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] GunRunner:
I flashed my zero with this ROM a few days ago. It runs good, but I have one problem. I reinstalled all my apps. For some reason, Nexus Media a importer is not working. Any ideas?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
That definitely shouldn't be happening. Have you installed any apps/scripts that claim to "turbo-charge" your device? They sometimes do stupid things that can cause this. On the other hand, there could be, for example, file-permissions issues that prevent the files from being saved. For something like that, I would need a logcat.

If you have PhilZ, you'd know 'cause it says so. If you just have CWM, I'd install PhilZ because it has more features.

As much as it pains me to say this, your best bet is to let Windows format it as a large floppy using either exFAT or FAT32 (I don't recall what the FAT32 limit is: 32 or 64gb). By "large floppy", I mean unpartitioned - essentially, the way it came from the manufacturer.

Hmmm... what's a "zero"? Your S7P? Anyway, while you may like the Nexus Media Importer, it isn't needed with this ROM. Support for USB OTG-attached drives was the first thing I added when the kernel source code became available. Files on your flash drive should be directly accessible by any app without you having to do anything (it might be a good idea to unmount the drive in Settings->Storagebefore you disconnect it).
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] GunRunner:
Sorry, I fat fingered it on my phone....Sero, not Zero, lol. I tried using my thumb drive with my OTG cable, and the tablet wouldn't read it at all. The led on the drive flashes when plugged in, and that didn't happen when plugged into my tablet. I have tried the cable/drive on my GS5, and it works fine. I reinstalled Nexus (I used it when I had the stock rom), and it will not show the drive either.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kc12:
Hi. Just wanted to share some information.

Regarding the optimizing after restarting: When my S7P starts after a reboot, after the dopa animation, sometimes it says "starting apps" a few apps load, then it comes to the home screen. But not all the time.

Regarding the USB storage and the cable: My S7P can't read any usb storage devices with the cable either. I have checked the cable with other tablets and it works. BUT, I have a micro sd card reader that plugs right into the charging port (no cable needed) and it can be read without issues. One of these.

Thanks for the note back!

An update on my end I went with FAT32, had issues initially partitioning with "aParted" locally on tablet & "MiniTools Partion Wizard" on Win7, so tried Aomei Partition Assistant via Win7 to partition and it worked flawless.

From there I installed philz via zip in ClockWork Mod Restore. Made a backup to sdard1 of my stock US rom, successfully writing to ext sdcard :)

Then formatted /data and /data/media (/sdcard), and tried to install this custom rom & the earlier 4.4 kitkat, but got errors back....Tried to recover to backup of stock... and still permissions errors.

Realized maybe I need to re-root and found under advanced options "re-root system (supersu)" which did the trick.

Then I was back up and running, loaded this AOSP 5.1 DOPA via zip under philz and it's a sick ROM. Love it!!!! Great work and thanks for all the info!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] TheLoonyRebel:
I saw mentions of people having issues with the latest recovery (the one in the OP) is working 100% for me both backing up and restoring regardless of it being Kit Kat or Lollipop ROMs. Might help that I have a new micro SD card in the tablet (Samsung 64gb) but so far no issues with either backing up or restoring. The only thing I noticed that's odd is that AROMA installers like this one:

http://xdaforums.com/android/general/gapps-lp-gapps-pa-gapps-aroma-installer-t3010798

The GUI on the AROMA installer is only taking up the upper part of the screen compressed in while the functionality still is using the full screen of the tablet.

Still running the DoPa5 v1.1 build here which is fantastic. Very solid and smooth running. Just curious but how ready is the kernel included with DoPa to be used with CM12.1 based ROMs like AICP (Android Ice Cold Project) ROM?
