Someone asked for a newer version of recovery. Well I turned off cpuquiet. turned off overclock, and built a recovery from the newest twrp source code I could find.

As normal, this is all an expirimental forum so you need to use at your own risk. The sero 7 pro's have been all over the board on how they react to rom builds. Some work really well and some seem to have problems that I can not reproduce. Then I have had problems that were only on my device. That said

here is twrp 2.7.0.0 for the sero 7 pro 8 gig US version

Well I dont even remember where they were. However, they balanced performance with battery consumption, manually. In Kitkat and I believe 4.3 as well those were removed, not because they were accidentally left out, but because they are no longer required.

The old way, you would select performance to get something fast like games, the device would lock all cpu's on full speed. Balanced, would allow the cpu governors to work, and battery save would put the cpu's in a low speed mode. With the screen off and in balanced mode the system would shut down all but 1 cpu and put in into a low speed mode.

Now, system leaves all that to the kernel, if nothing is going on, just sitting there with the screen on the cpu's except for one get shut down. soon as something needs lots of power, all 4 go to full. if the screen is off an nothing going on, all 4 cpus are shut down, and a low power 5th core comes online at a max of 500mhz to take care of basic house keeping. If something weird would happen with the screen off that needs power the low power core will throttle up to 500mhz and bring the other bank of 4 high power cpu's back online.

If you really want to control power consumption manually, go into performance in the settings menu and you can change the cpu governor and the cpu clock speeds.

This is a lot better than us trying to all the time manually control the mix with just 3 settings.

Cant locate the Performance Setting

Thanks for the detailed explanation. I agree an automatic approach to performance and power management is better (provided it really works). I will keep testing, etc. I could not find the Performance setting you mention. And now wondering if my install of the ROM might have gone wrong some where. Any ideas?

Which Gapps version to flash for the CM11 ROM?

I did not realize their is a CM11 stable build that is fully working. I too like CM and want to test it out. I tried to flash it and it installed fine. But I keep getting a "Sorry ASOP Keyboard Stopped Working" error and end up with no keyboard available for use, etc. I understand this means I likely do not have the correct version of GAPPS for the CM11 ROM and need to flash it (please correct me if I am wrong). My question is how do I know which GAPPS version to flash?

Is the Privacy guard in this rom the same as the nightly build? Cause I liked the options it had especially the 'always ask' one
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Might not be the same. Stable is a line of source code that suppose to be more reliable.

The nightly give up reliability for features. Some features are experimental and may cause trouble but the next nightly could fix it.

As the name suggests nightly updates nearly every day.

Stable updates rarely. Cyanogenmod has promised monthly updates

I have been using this on my SGS3 for months now, and it is so much better (imo) than any of the other recoveries out there. This would be the "killer" recovery for the Sero 7 Pro.

Just saying :)

Flashing the kernel fixed the lost key but not the WiFi drop. Clean flashing back to 3/14 fixed both.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
I do not include gapps because a while back cyanogenmod was contacted by google and informed to remove the gapps from their builds. Google did permit gapps to be used but only as a separate flash-able zip file. Around the same time AOSP also removed gapps from their builds.

Since most of my builds are cyanogenmod I figured I better not build gapps in.

Weird, there is no difference in the any of the wifi between 0314 and 0325. There was a difference in 0317 but the difference should have only effected P2P and since P2P was disabled I do not see how it caused a problem. But on some sero 7 pro's it did.

as for wifi going to sleep all broadcom types seem to have the issue.

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
You need Trickster MOD, and on the Specific screen and change the cpuquiet governor to runnable. Not it still has some issues and that is why it is not the default setting. So I would not recommend setting it to be used on boot.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dgjenkins:
Just have to say that both the 0326 build and the newest TWRP are running nicely. Wifi still seems to drop every once in awhile (but not always) when the screen is off regardless the settings, but it fires back up as soon as you turn the screen back on. In that respect it's no different than the 0314 was for me.

I haven't had anything to flash with TWRP yet but it's done everything else I've tried. Next build... :)

Thanks Dave!

I'm running the stable ROM and am having no problems. Thanks Devs for all the great options for this tablet. I was wondering, tho, if its possible to get a tablet UI on this ROM. I've tried using the phab7 module and xposed installer, but the tablet UI is greyed out - says not available on this ROM.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] lexridge:
It seems to work very well! Yay!! When I had ask if you had ever used it, I didnt mean you had to port it immediately. Great job Dave! You da man.

It has not been tested well, I only did a backup and restore using it. There are so many options, it could literally take a few weeks to test it all. I will test the flashing functions soon with your new "stable branch" release, but probably not until Friday afternoon.

EDIT: Hell, I couldnt wait. Sleep can wait. lol. I am very happy to report that flashing works too!!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] chopin_k:
Thanks, I switched to runnable, I got up from 14k to 14400 in antutu and every CPU state but 51 mhz was reported used by trickster, sadly wifi started dropping on me in the middle of using it, I wonder if going so low on CPU freq would have anything to do with it, tomorrow I'll try setting the lower limit for the CPU to the same as the default governor and toying with the wifi always on setting to see if it makes a difference.

BTW could wifi security mode cause have anything to do with inconsistent wifi issues we seem to be having? I'm running on WPA2 personal (so AES) and other than the runnable governor thing and the wifi not staying up on suspend I have no wifi issues.

ASOP 442 Battery Life?

I am struggling to determine which ROM is better (ASOP 442 or the CM11). After tinkering with the ASOP 442, I can't believe I am saying this but I like it a lot. All the customization and simplicity via KitKat coupled with XPOSED and Gravity box is fanstastic (plus I added Apex Launcher). The only thing I am not sure about is the battery life.

I had loved the stock Sero 7 feature (which was still on the XBOXEXPERT Custom ROM which I was using prior to switching to ASOP 442) of manually setting the battery/performance mode---always had it set to low and never had performance problems even during 3D games. Now I am counting on the ASOP 442 Kernal making the decision for me (which I don't exactly trust yet as I continue to test).

Do you have any opinions on the ASOP 442 battery life?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] alex_is_the_1:
I find it a little better on aosp then cm11. Might just be my device as I'm not sure how old it is. Also I've heard it can take up to 3 full charges to make things settle down, which should increase backup a little bit.

Great, but I'm curious about what's new, so I know what to test/look for.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] davepmer:
Well the stable builds are always behind the nightly builds. The new Stable build update added most of the changes that have been in the nightly builds over the last month. The changes that I made over the last month have been to build dbus instead of use the OEM dbus, Build libstragefrighthw instead of use the OEM, I also use a different wpa_supplicant than either OEM or Cyanogenmod. The last changes I made are to the kernel, changing some of the cpuquiet code and setting the default to governor to balance instead of userspace. I was trying to get better core control hoping to save some battery. General testing on how the kernel behaves with my changes may be a good idea, and you can swap out my changes with Trickster MOD.

As for all the changes that were added to the stable build from cyanogenmod, I am not sure. I do know that to be in the stable build, a lot of testing has already been done.

I just retested and find that you're right: V4A causes pretty much the same crash as the built-in sound effects do. The crash occurs several calls into a Hisense (Nvidia, actually) blob, so I can only hope that the cause is some identifiable change in the AOSP code that causes these problems further downstream.

Hi Guys, I need ideas. On any build with anything but cpuquiet userspace my tablet has started going to sleep and not waking up. Now for the weird part, only in a very dark place mostly my bedroom. Even then any internal event (alarm) wakes it up. Every time I get near my desktop it works perfect. It leaves NO logcat tomestone or dmesg error giving any hint that anything was going wrong. Worse like I said if I get near any computer that I could try to use adb, it starts working. Long before I get close enough to plug in the USB cable.

It gets even weirder, I was pressing and releasing the power button, bedroom nothing, decided to head up the steps to the desktop while pressing and releasing the power button. half way up the steps the tablet woke up. and continues to work great upstairs.

Before anyone suggests, I had wifi turned off. so it is not picking up some signal confusing it.

Working on the light sensor problem. Might try 04-01 but it is a nightly build so it would need a clean flash.

the 04-01 build uses as default ondemand and runnable_threads for the governors. CPU cores are now turning on and off depending on need. Compared to earlier builds where cpu cores stayed on the build may seem slower but I am hoping battery consumption will be down. If you want to try Trickster MOD you can set the cpuquiet governor back to userspace and lock the cores on.
