Did you use the latest GApps package? As Gazoo119 noted, that fixed a problem with another app that uses Google Play Services. If the problem persists, you may want to go to Apps->Google Play Services, then tap the "Manage space" button. On the next screen it lets you clear all data.

I hadn't tried GPS at all until you mentioned it. I installed Google Maps but couldn't get a lock at all. It's raining here, so I couldn't get fully in the clear. Instead I sat in my car and it still did nothing. Finally, I forced-stopped the app, cleared data and cache, then retried. This time it only took a few seconds to find me. I then turned off GPS, rebooted, and moved to my semi-covered patio. After getting everything going again, it took 10-15 seconds to get a rough fix (off about 70 feet) and it continued to hold it even after I went inside. You may want to try clearing Maps' data (if that's what you're using) to see if that helps.

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:

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.

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ObviousMan:
You are right, thanks. The GPS is really weak. I though Tablet S had a weak GPS receiver, but this one is worse. I loaded GPS TEST and it took near a minute to get a good lock outdoors (10m or better accuracy). Google Maps worked after that.

I see people saying the GPS in this tablet is weak....why does the Omni rom and cm11 rom connect in seconds?

just a observation...but this rom is faster and smoother for me....

Mike
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ObviousMan:
Good question. In stock ROM GPS has also locked faster for me. Is the drivers used for GPS in this ROM somehow make it weaker than in the stock ROM, or in Omni, or CM11? I also like this ROM better, but GPS does appear to suffer for some reason.

I've noticed the same thing concerning GPS. Locks on immediately on cm11 and omni. That's the only thing holding me back to keeping this as my daily, but I do love just plain stock android. Kudos to dolorespark for this build

I just bought a refurbished sero 7 pro from NewEgg. This is the 2nd sero I've bought, so I have had a good time flashing roms. However the USB port is faulty and won't charge so I need to return the tablet. I am trying to return it to stock. I didn't have any problem doing this when I had xboxexpert's cm recovery on it. Then I put a selinux cm recovery on so I could run this rom of dopa's. Now the cm recovery won't install the stock rom zip. Aborts each time I try. I am looking for a zip file with the original cm recovery. Does such a thing exist? I would appreciate any help or suggestions.

EDIT: I finally could wiggle my cord around enough that the computer would see my tablet. I was able to run the adb script from dopa's 4.2 roms. Success! Tablet is now back to stock.

Crash Reboot

I am using the latest version of Plex Media player and when I play a video the tablet crashes and reboots.

I have tried several players and the same thing happens. The only way I can get videos to play is to use MXPlayer and force it to use software decoding. This works consistently but does have direct impact to batter life.

This seems to be related to the hardware video decoder.

Any one else seen this?

Very odd for sure.

Thanks

Plex isn't crashing for me but can confirm its not working correctly.

When I play a video in Plex audio studders and video is in slow motion like its not using hardware decoding.

Netflix and Hulu+ seem fine though.

Running the latest Dopa 4.4.4 with the NTFS kernal. (clean flashed)

Maybe Plex doesn't like 4.4.4? :eek:

Posted by Plex employee on their forum..................

We're aware that some users are experiencing playback issues (typically "stuttering") after updating to Android 4.4.3 or 4.4.4 OS releases. This issue affects other apps besides just Plex and it has been reported to Google. The issue is being investigated, but there aren't any workarounds to offer on this currently, unfortunately.

If you have not yet upgraded your Android device, you may wish to refrain from doing so if you stream content with Plex (or some other apps)

If you've already upgraded, you might investigate downgrading to the 4.4.2 Android OS version

hello, this look awesome. just picked up a few of these from newegg as refurbs for me, my wife and daughter and been looking for a way to update them.

im familiar with how to flash and all that from many previous devices but i have never had one of these in hand before till today, my question is which is currently the best recovery recc. to use? i see a number of different ones and not sure what the differences are. cant wait to get this flashed. hoping to do this soon if someone can let me know.

thanks, question though for the moment i went back to stock on the one i was flashing last night and i cant get the newest factory update. its stuck on .11 instead of .20 like my other ones are. if i wait will i eventually get the newest update (not sure if my wife and daughter will like it with 4.4.4 after i flash them so if i want to go back to stock i want to make sure i can get the newest hisense updates again)

one of the major reasons i wanted to use a newer rom was to be able to move apps to sd card like i can on my asus memo pad hd7. i was hoping this would have been included in this rom. so what can i install to be able to do that? i dont want to fully run apps off the sd card but move part of the data like i can on the asus hd7. can this be done? otherwise its running great!

thanks again.

FolderMount will move large personal data files. Link2SD can be used along with this to link apk files if you wish and/or associated dex , data and lib files. You will need a second partition on the microSD card for the latter app. Others have been able to use Ext2,3,4 formats for that but my experience is FAT32 works on my unit but the others don't. I am running Dopa's V2.0 oc (JB 4.2.1).
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] mastershak:
basically i really want to bring back the "move to sd card" button. the asus is on 4.2.2 and has this button. even the stock pro 7 rom was 4.2.1 and is lacking it. is there any way to bring this back to work the way it used to or does on the asus. i tried link2sd and not really what i was looking for. can this be done somehow?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
"Move to SD card" doesn't exist on this device because you don't have an "internal SD card", you have an emulation of one. What's that mean?

Older devices had a separate partition labelled "internal SD card" that you could put your stuff on. Then Google looked at actual usage and found that many users were running out of space on their '/data' partition where your apps' data (and most apps themselves) are stored while the internal SD card partition was going largely unused. To maximize usable space, they combined the two and added a software layer that makes a particular subdirectory on /data look and (sorta) act like the internal SD card of old.

Since '/data' and 'internal SD' now share the same space, "Move to SD card" has become meaningless because you'd be moving stuff from one directory to another on the same partition and not accomplishing anything useful. If you're truly running out of space, start by moving your music, pictures, etc., off the "internal SD card" to an external SD card. If you're still in need, try some of the apps recommended in earlier posts.

P.S. if you want a copy of the stock ROM, go to this posting and look for the link to the 6.02.20 update at the bottom.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] mastershak:
i see. kinda stinks imo. ive been searching everywhere trying to figure this out driving my self crazy all day thinking there must be some way to bring it back.

just being curious how is asus doing it on the hd7? did they build that into their own asus rom? could i create this partition and somehow use it?

so in your opinion what would be the best possible way / program to use for that purpose? my wife is kind of set on using it because her old memo pad hd7 had it (it died which is why i grabbed these for the family).

thank you for the stock rom i missed it and am glad to have it just in case.

lastly which recovery do you recc as the best to use with the 4.4.4 is one better than the other really or just they really pretty much just offer different features?

thank you for all the info. hopefully i can get these all working the way everyone wants them to. sorry for all the questions just wanting to try to get it right in one post.

I installed sero7pro-winfs-dopa1-v2.0 on my SD card and tried flashing it, but the install crashed.

Now, I'm stuck in a boot loop and the battery has drained down to near zero. :(

Is the loop related to the low battery?

EDIT: I was able to get into recovery and tried to flash the updated ROM, but get a Status 7 error message.

EDIT #2: OK - I got into recovery and did a wipe/factory reset. Now on reboot I get the Hisense screen and nothing else. When I plug the tab into my desktop it tries to install the driver but fails. The driver had been previously installed before this problem began.

How can I get past this soft brick issue?

I use Mounts2SD which is available unlocked in another thread here at XDADevelopers, You can move any of several mount points to a secondary partition on the external SD card.

here is another quirk that i noticed but not sure what the cause is. when using the 'standard' 4.4.4 gapps from the link provided http://xdaforums.com/google-nexus-5/themes-apps/standard-minimal-gapps-t2012857 i'm getting some not-so-smooth transitions in the animation from the app drawer button (or whatever it is called) to home screen. press the button, and press it to go back and it is kind of jerky. It isnt too terrible, but I can notice a difference. I did not notice the same jerkiness when using the stock launcher that 4.4.4 gapps replaced.

maybe I should have used gapps minimal instead?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] mastershak:
it seems this version drain the battery MUCH faster for me. at least it seems that way. the original rom lasted about 6-7 hours of straight use this rom the battery seems to be dying in about 3.5-4 hours to where i have to plug it in or it just will not function. my daughters asus memo pad hd7 had a battery optimize thing from asus that seems to REALLY help save battery life. when i turn off the optimizer battery life is cut much shorter, is there something like this i could use with this rom? if i can get all the little things ironed out id be happy to donate also.

someone mentioned using adb to remove the extra keyboards is there a tut somewhere explaining how to do that? again ive flashed many devices but i am very new to customizing anything with them.

also forgot to add gravitybox will not run for me. tested on three of these it says it stopped responding and has to close?

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Both of you are reporting fairly ..umm.. non-standard problems. Did you wipe your '/data' partition before installing this ROM? If you were coming from an earlier version of Android, you'd encounter all sorts of odd problems if you failed to do so.

For the vibrate problem, I'd check to see if there's GravityBox setting that's overriding the one in Settings. If not, I'd go into Settings->Apps->All and clear data for some of the system apps, especially SystemUI.apk. For GravityBox, did you go into Xposed Installer and enable it and the modules you want to use? After doing so, you have to reboot to put the changes into effect.

The other keyboards can be disabled in Settings->Input & Keyboards (I'm at work & don't have my tablet available, so the name may be slightly different). Just uncheck the ones you don't want.

I don't use mine intensively enough to run the battery down all the way but I'd be surprised if any ROM gave you 7 hours with the backlight on. Have you done all the usual things to conserve power? I.E. turn off NFC, GPS, and Bluetooth when not in use, avoid setting screen brightness too high, etc. Then too, some of the apps you've installed can drain power because they have the system start themselves even though you're not using them. An app like Greenify can keep them from running until you explicitly start them.

BTW... speaking of power consumption, I find I get much lower battery drain while the tablet is asleep if I set "leave WiFi on during sleep" to "always" rather than "never". Has anyone else noticed this?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
I do here, it definitely drains power faster but not really much more than my other devices.

New Version Available

I posted a new version of this ROM: AOSP 4.4.4_r2 DoPa v2.1.

This is a minor update that integrates NTFS and exFAT into the ROM and upgrades AOSP 4.4.4 from 'r1' to 'r2'. If you've already installed the NTFS/exFAT packages, there's little need to install the new version ('r2' is virtually unchanged from 'r1' and I have no idea what it may fix - perhaps the Plex Media Player problem?).

Regardless, if you want to upgrade from DoPa v2.0, you can flash it without having to wipe anything - the installer will wipe 'cache' & 'dalvik-cache' for you. Reinstall Gapps and you're good to go. If this is a new install, you'll still have to format '/data' (as always).

can i somehow get rid of phab7, and gravitybox and exposed. im not using them unless the rom itself relies on them (which im unsure of). i do everything to save battery. when the stock rom when i check under battery (i know not fully accurate but gives me a idea) the display normally says under 30 many times even down under 10. the kitkat install my display sets at around 63-64 steady even if i turn the brightness just about all the way down.

Unable to install this ROM via TWRP and other issues...

Hi,

I have been unsuccessful in installing this ROM with TWRP 2.7.1.0. Fails on creating symlinks during installation. Also on previous versions I've had issues where as soon as I first boot, I get constant error pop ups about AOSP keyboard shutting down. The keyboard is not usable at this point. Only way to get keyboard to work is replace it with a different keyboard like hackers keyboard. I always clear all data, cache, dalvik and system before installing any ROM.

Hi,

Thank you all for the replies. I have gone ahead and retried installing the ROM and this time it worked. Rebooting into it for the first time also had no issues. ROM works like a charm. Battery life is great as well. Thanks for a great ROM.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
I was highly skeptical that any of these ROMs would have a significant effect on battery life. However - depending on which ROM you're comparing this to - I may have been wrong.

I did some investigating and found many Tegra3-based devices have a system app named NvCPLSvc.apk that supposedly increases battery life by 15-20% (though no one could actually confirm this). I looked at the stock ROM and it was there but was missing from my AOSP builds - I had simply overlooked it.

I installed it and confirmed that it ran OK. I then noticed that it saved some settings and wondered if they could be tweaked. Since the app doesn't have any settings panel (or even an icon), I reinstalled the stock ROM to see if those "Power Settings" in the Settings app had any effect. Actually, what I installed was Hisense's last update (build 6.02.20) since no one has a genuine, out-of-the-box stock ROM. To my surprise, Android refused to load the app, saying its signature didn't match the other system apps on that stock ROM.

So... it's very possible that you got better battery life using the fresh-from-Walmart original ROM. However, if you let the thing install any updates, those savings would have disappeared if NvCPLSvc is what provided them (since the update broke it). Since it works fine with my AOSP builds, you and anyone else who's interested can reinstall it and find out if it really does anything useful. I've packaged it as an installable zip that you can flash via CWM or TWRP. I've also packaged an uninstaller in case it causes any problems.

sero7pro-nvcpl-install-aosp44x.zip - install NvCPLSvc.apk
