Well the tombstone was kindle must have crashed sometime. The logcat tells me something weird, for some reason (it says reason 0) the wifi disconnects, then the device first tries to connect by blue tooth tether ??? We might have the ability for blue tooth tether but I have never tried it, worse is the next attempt was to connect by ethernet. I know I do not have ethernet enabled. the fail was on rearming the actual wifi chip and trying to reconnect.

As for having it wiped, I am not sure, it still wants to disconnect when sleeping, and although it behaved on my walk going into places that before caused a soft boot it still soft booted waking from a sleep.

Wish I could find why it is disconnecting.

Has anyone actually set the WiFi region code in advanced WiFi settings?

After I did that it looks like it doesn't require to retype the password again and it stays on:confused:
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
OK I know someone had said it before. But, I seem to stay connected in sleep better if I set the wifi stay on during sleep to never than to always. I am almost afraid to see what happens if set to while on power only. Kind of afraid it will stay on while on battery only.

---------- Post added at 01:50 AM ---------- Previous post was at 01:49 AM ----------

I have tried setting it to see if it would stay connected, but it did not help that,,, what region did you set it to? I believe if you do not set it the default is US
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] rodos15:
AU but it disconnects I didn't give it much time to sleep :) , at least it keeps my password.

I have a three WiFi routers setup with the same ssid the two have dhcp disabled one is the server and it doesn't reboot the tablet.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
wow that is the wireless setup (multiple with same SSID) that has been causing the soft boots. Did you try telling it to never keep wifi on during sleep?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
Sorry but this is a little off topic, but is Sero 7 Pro related. Has anyone fully disassembled this tablet? Can the glass digitizer be replaced? My wife was carrying my tablet and put it on the roof of the car while putting the baby in.....forgot it....I thought she had it and as I was driving down the street I heard a bang. I knew what it was. I pulled over and races to the street where it fell. It was unscathed in the middle of the street, that is till I tried to get it. Some $%&* swerved and purposely ran it over as I was going after it. Despite having been ran over, the tablet booted up and it works!! All except the shattered glass touch screen. I searched the web and found no concrete solution. Someone said the glass is glued onto the lcd screen itself, and Hisense doesn't sell any replacement parts, just refurbs. Any input would be appreciated.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dgjenkins:
I've been reading all of these issues with AP hopping rebooting the device with great interest. I don't believe I've ever had this happen and I work in a large corporate office where I'm surrounded by AP's broadcasting multiple SSID's. I have four AP's within 50 feet of my desk and one large conference room that has 76 AP's in it (don't ask why). I routinely take my tablet to the gym, which is a walk through three separate buildings, and I've never had it reboot. I do have "keep Wi-FI on during sleep" set to always but other than that it's just at whatever the defaults are on whatever rom I happen to be running.

---------- Post added at 05:12 AM ---------- Previous post was at 05:09 AM ----------

Now that's a sad story. Don't know the answer but sorry to hear that happened!!!! At least she didn't put the baby on the roof and the tablet in the car...:D
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Check eBay, I saw replacement (used) screens for the sero 7 pro not too long ago. The back comes off really easy so it shouldn't be too hard to replace the whole digitizer LCD assembly
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] rodos15:
Never keep wifi on during sleep, connected to first router, left the tablet on top of the second router in another room and checked it after two hours - the WiFi was disconnected but connected on the nearest router without restart.

I had running WiFi Analyzer in background and checked the connected routers mac address.

No problems for me then...
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] boonesmi:
Dave. I've been using your 03/14 build a couple days, and its running great.

I've never really had any reboot or stability issues (but my device doesn't move around much to other networks)

BTW, its sure nice having full functioning HDMI :)

I just wanted to report in that all is well on at least one device.

Ohh, I almost forgot to add that battery performance has improved slightly (but noticeably) maybe just cause its not overclocking... although on all your previous builds I did set CPU speed to 1300.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
Yeah I'm pretty angry about the situation. Thankfully the baby is safe.

---------- Post added at 01:43 AM ---------- Previous post was at 01:30 AM ----------

Thank you for the info. I disassembled the tablet and separated the digitizer glass from the lcd. The tablet works fine, the lcd is flawless. I tried finding a Chingwa digitizer glass replacement but had no luck. Its identical to the Nexus 7 except for the ribbon cable is different. I looked on Ebay and there is someone in the UK selling used scratched screens for $56 + $17 shipping. Might as well buy a refurb. I'll have to keep looking.....I'm still shocked the rest of the tablet survived being ran over by a car.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] foltz61:
Did you ask Hisense how much it would cost for them to repair it? My nephew broke his RCA tablet screen. They only wanted $25 to repair it. The screen waa on Ebay for $35. Good luck.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well my test build is working at church without a soft reboot.

Also not sure if it matters but the broadcom driver was modified for

4.3 and all the power control routines were removed. The routines set the sleep power states.

Also the p2p routines were removed. As well as back ground scanning.

I put the p2p back, but haven't tested yet, I added background scanning into wpa_supplicant and added roaming into wpa_supplicant. I can't add power control there so hoping I can add some things back into the driver. Hoping it will help
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
Awesome news, Dave!

So if we were running 4.2 it would work ok? (But I like my 4.4 :crying:!)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Pretty much, they pulled the functions out with 4.3. Not sure what the idea was for pulling the p2p, they just did
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
All I can do is try. :/

UPDATE:

I called Hisense and the said they do not sell parts or do repairs. If I bought the 2 year warranty, could return the tablet to stock, they would of replaced it for free. Since I didn't buy the warrantee, I was given 2 options:

1) Find a seller of an OEM or used digitizer or digitizer screen assembly online. Which is near impossible....not cost effective.

or

2) Pay for shipping, send the old one back in then pay $60 for a refurb.

So that's that. I might be able to reassemble it and wipe the internal memory via adb...but not sure its worth the effort.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] MadGoat:
amazing rom! Quick, fast and Very responsive. New Life into my Sero!

One question, whats up with the camera app? I cant change the storage to external... AND it's stuck on 2mp? My phone with 4.4 has many more options in the camera app available... am I missing something?

Also, It seems Google Music will freeze and crash the tablet with this rom... big bummer...

One other thing, Pattern lock is broken? It FC's when attempted to set up...

TY ahead of time and for the awesome work on the rom....

Added: Upon further inspection, it seems anything that requires heavy WiFi usage... will freeze / crash the tablet... this kinda of makes the tablet fairly useless ...

Yup, google music that is "streaming" music, flips the tablet out.... after downloading my playlist it works fine... but heavy wifi usage / streaming kills it.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] boonesmi:
what rom are you using? daves latest build? or the r13 from the OP?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] MadGoat:
i suppose i am using r13... have I used the wrong one?

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
I have been working on getting the wifi to handle things better. WiFi disconnect during sleep is still out of my grasps. But test builds are doing better at not crashing the system.

Last test build had one crash so far, and that was when I just woke up the tablet, but it was gps crashed. Have not had it happen since.

BTW adding power control to bcmdhd did not keep the wifi awake

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well anyone want to try this? I have been running most of the changes all weekend. The last group of changes were to the kernel but I have been running even them all night.

https://www.dropbox.com/s/wtzx13yrlbibtzn/cm-11-20140317-UNOFFICIAL-m470.zip I highly recommend a clean flash.

use https://www.dropbox.com/s/idr2lhq8v61lheb/m470-add-overclock-20140317.zip to allow overclock

and if your tablet dont like over clock use https://www.dropbox.com/s/qzvzef7stxzi337/m470-remove-overclock-20140317.zip to remove it.

This build has added background scanning and roaming to wpa_supplicant and some power control added to the kernel. I have not been able to tell if it always stays connected but it connects really fast. These changes are the ones I was using at church yesterday when my tablet handled multiple routers with the same SSID without a reboot. Come to think of it I have only had one reboot so far with these changes and that one was the gps crashed. I have used gps since and have been unable to get gps to crash again.

Note, due to kernel changes you can overclock my older builds with this overclock, but do not use the older overclock with this build. You will loose features.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
Installing right now, I'm curious about background scanning, is it just that it keeps scanning for access points while already connected?

My "test" for always-on is having youtube up before putting it to sleep, it will try to refresh as soon as it wakes up and you get the connection error message all over it. Or I can look at device connection time on the router.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
I needed background scanning to use roaming. Background scanning had been a normal function inside bcmdhd until android 4.3 then it was removed, without any reason given.

I could add it to wpa_supplicant so I did. But with just background scanning multiple same SSID's still caused a reboot.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] tinybeetle:
I hate to sound like a noob, but how would I go about installing one of these Roms (like Davepmer's) onto my Sero 7 Pro? I'm currently running Dopa version 1.

Thanks.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
I'm really curious about why they would remove all these features from the driver, other than some archictecture change in the OS that moves those functions out of the driver it seems they just chose to gimp it.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dgjenkins:
So far I'm not feeling the love here. I installed clean and rebooted. Upon starting back up I had to re-enter the password (a simple pre-shared key) because it had been lost. I then threw the tablet in my gym bag and headed to the gym. Pulled it out in the gym just as it finished re-booting. After working out found that the network I was attached to was in a disabled state. By the time I finished taking a shower it had cleared, but had lost the password again. Re-entered the password and walked back to my desk, this time going outside so I was completely out of network range. Got back to my desk and hit the power button. Went to look at the network settings and the device re-booted again.

This is all with completely stock wi-fi settings on a clean install. I'll play with it throughout the day as I have time and try to get a logcat but right now, I'd say whatever you changed probably wasn't the magic bullet. Sorry to bring bad news!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Can you tell me how 0314 behaved on your device? This may be really hard for me to trouble shoot as I am not having these issues. In fact I have only had the password lost problem when I had some app switching settings on boot. I have not had to reenter a password since I stopped the app from changing setting on boot. The app changed cpu governors. so it had nothing to do with wifi but somehow it was doing it. On my device, before this build all the other builds did the reboots if I was in an enviroment with a lot of SSID's with the same name or sometimes with just open APs but I have not had one since I switched to the test build that this is based off of.

---------- Post added at 06:45 PM ---------- Previous post was at 06:41 PM ----------

The commit that removed those from the code said that the power sleep functions were moved in 4.3 and no longer required. It did not explain why they pulled back scan or p2p. BTW it sure would be nice to find out what suppose to have took over the function of power sleep, because the options for power sleep seem to do nothing.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dgjenkins:
I actually never ran 0314. I had no problems on 0307 but then I've been on pacrom for most of the last week until I installed this build. I did manage to capture a couple of logcats though. I'll attach them in a minute.

Edit: Here you go. Some interesting things to do with wpa_supplicant.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] SacredMyths:
I myself so far am not having any problems.

The battery seems to be lasting longer, my wifi isn't disconnecting and reconnecting when i press power button and rebooting like it was before.

I've been a fan of this thread since it's beginning! I've tested every one of davepmer's builds from 0213 to today's release (and Taktik 9, 11 and 13). I didn't test many features like HDMI or syncing Bluetooth to a speaker, but I tried putting each build through its paces as much as possible. I only started having WiFi disabled/password forgotten with 0314. I've updated to 0317 and only had the password drop when I grant SuperSu and reboot. It happened when I installed SuperSu and after installing viper4android; granting root access and rebooting.

Ah??? My builds are rooted with Superuser already up and running, Why did you need SuperSu?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ericeo:
Installation of Viper4android only seemed to work with SuperSu. I tried installing the driver with Superuser and it kept failing. Its been reported in a few posts here stating SuperSu is the way to go, so that's the only reason I tried SuperSu.

I also ordered a mini HDMI so I can test out HDMI on this rom. I'll post when I get a chance to test.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
This.

SuperSU seems to be more stable as well as less buggy. The first thing I do after flashing a ROM is installing the SuperSU binary.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well I installed viper4android, and SuperSU. And rebooted. I haven't re entered any password least not yet but it connected.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ericeo:
I tested it twice with clean installs of the latest build. Both times I completed initial setup which included setting up WiFi (connecting to a Linksys E1200 N router). Next I installed SuperSu. On reboot I lost WiFi password. I re-entered password and installed Viper4android. After that reboot it again lost WiFi password. I reentered password and it has held for every reboot. No complaints at all with this though. I figured there might be conflicts running two root apps side by side, so the side affect was expected.

I also wanted to note, I'm using the latest 0314 Gapps.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well what has me confused is why some of the sero 7 pros are so different from one another. Your's forgot the wifi passwords when you installed viper and SuperSu. But mine did not? Either they both should have or neither should have.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Bdadd34:
My tablet acts differently depending on rom..never had a problem with remembering wifi setting on gummy ROM with super SU but when I install carbon rom with superSU built with same device, vendor, and kernel it loses wifi login info anytime wifi is turned off and on. If I don't flash superSU on install and use built in superuser wifi works normally.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chrisdaun:
Clean install with this and it looses WiFi password every time the wifi is turned off and back on or the tablet is rebooted.

This was happening even before installing Super SU.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Try this, just drop to recovery and install the zip. It will wipe out all your wifi passwords. Tell me if it will remember the passwords after you enter them after

the device reboots the first time. It is really hard for me to trouble shoot this one, because my tablet is not doing it. Mine remembers the passwords after install, after installing viper, after installing SuperSu and I even tried wiping everything and installing SuperSu (still remembered) and then viper and still remembered.

I have two Sero 7 Pros using davepmer's 03/14 build and have not had a problem with HDMI, both video and audio. I'm using XBMC and it works great. If there is anything that I would mention, it is that you can't adjust the volume when connected to HDMI using the tablet, I have to control the volume on the TV. The tablet just goes from 0 to 100 when pressing the volume up/down button. I don't really consider this an issue as it could be considered normal operation to just use the TV volume. It might actually be more cumbersome to have to adjust both the tablet volume and the TV volume to get the volume you want.

I tried installing this over your 3/7 release and it resulted in repeated "com.android.phone has stopped" messages. And me being dumb I didn't make a backup first so I'll be wiping and flashing back to 3/7.

This time I'm not going to install a separate SU (which I had flashed a SuperSu zip to get TitaniumBackup to work) to see if that makes a difference. I'll report back if this does/doesn't make a difference.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Yep it would, it was meant for the 0317 ROM. Thats a different kernel than the 0307 ROM. Installing 0317 from 0307 requires a clean flash. Not sure if you could use one of the first zips to remove over clock or not

---------- Post added at 09:46 PM ---------- Previous post was at 08:50 PM ----------

But if you are going to wipe and do a clean install you might as well use 0317 or 0314 both are made from the cm-11 stable source code. 0307 was made from cm-11 nightly. the nightly builds tend to have bugs. But you can not dirty flash from nightly to a stable build or from a stable build to a nightly.

---------- Post added at 09:58 PM ---------- Previous post was at 09:46 PM ----------

Interesting, I found the wifi_sleep_policy comands in the source code, and in the wifi control that suppose to control them. I set all the commands to keep wifi awake always. I even took out the control to turn off the screen. Screen still turns off, and wifi still sleeps. Well at least I know why the controls don't work. Now to dig to find power control. It has to be in there somewhere.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ericeo:
I had the exact problem with 0314 rom, but not the one prior or the current rom.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
Wow that's interesting, they like just changed how power control works, no looking back.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well I know they removed the power routines from bcmdhd with the switch to android 4.3, they removed power control, back ground scan and p2p at the switch.

The commit only said that the power function had been changed in android 4.3 and no longer needed to be there. Would have been nice to tell me where it was moved to. They also did not give a reason why they removed the other functions. Background scan has been available in wpa_supplicant for a long time so I turned it on, p2p I still have to fight. Power control is becoming a quest.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:

Edit - Testing the WiFi test zip first...

I left My tablet on and connected to WiFi. I then put it on charge and left for work this morning. When I got home and grabbed the tablet,WiFi was not connected, but was enabled in the quick menu. When I went to WiFi in settings, it showed as disabled. I tired connecting without success. I toggled the WiFi on and off twice, forgot WiFi in settings, and re-entered the password. It connected after that.

I might try another clean install, but run it without installing SuperSu or Viper4android. In fact, I'll try the ROM with only Opera and the kindle app for a few days and see what happens. Maybe it is something with gapps 3-14. I wasn't having this issue with gapps 2-27.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] boonesmi:
mine also syncs fine. i didn't have to change any settings or configure anything... i downloaded calendar from app store and within seconds of starting the app it was already showing events (i didn't even need to log on, i guess since the tablet was already logged on my google acct for email.)

might be a stupid question, but do you have more then 1 google acct?

** edit to add. I'm running ROM from 03\14
