Thanks for the quick reply! Yes, I've formatted the partition using PhilZ Recovery by using the "format /data and /data/media" option, and I've also tried using TWRP just in case, but it didn't make a difference. I've tied formatting the external partition using different utilities, and I've also tried using different versions of the app. I think at one point, I tried the whole process while standing on my head holding a wine glass, and still got no better results. :D

I am presently waiting on yet another 7 Pro (with a broken screen) that I will use as my test bench. And I will definitely follow tinybeetle's advice and just copy a backup from the other tablet so that my kids can both stop vying for the one that's working, but now I'm curious to find out what's causing all the fuss!

HDMI Output Resolution

I apologize if this has been detailed somewhere else, but after a bit of searching, I am unable to find the answer. How is one able to adjust the output resolution of the HDMI connection? I am unable to find any setting in the DOPA 2.6 ROM, or in the stock Sero 7 Pro firmware that allows for resolution adjustment. When I plug the tablet into a HDTV via HDMI it appears the tablet is outputting the native 1,280x800 resolution. I found a couple device reviews that specifically mention playing output video at 1080P and the written manual for the Sero 7 LT goes as far as describing the HDMI settings under Settings -> Device, that I do not see on the DOPA ROM or Sero 7 Pro stock firmware. The Sero 7 Pro manual does not mention any HDMI settings.

From page 23 of the Sero 7 LT manual, available on the Hisense website:

HDMI

When the Sero 7 is connected to external device's HDMI port, you can adjust the HDMI resolution, screen zoom and screen timeout.

Can anyone confirm that this setting ever existed on the Sero 7 Pro? It wouldn't make sense, but perhaps the setting is only available on the Sero 7 LT?

Thanks!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
The S7Pro has no HDMI resolution adjustment.

I just tried connecting it to my overpriced, crap Samsung SmartTV, and the TV claimed the signal was 1920x1080@60P. On my first attempt, I couldn't get any sound, so I pulled the cable & reconnected. I then had sound but the image appeared to be only 1280x800 in size, sitting in the upper left corner of the screen. After starting the Google Play Movies app, the image expanded to full size and stayed that way. I was surprised to find that the Android screen image rotated when I rotated the tablet (I didn't think it was supposed to). However when I played some hi-def "content", it went to landscape and stayed that way regardless of the tablet's orientation (as it should). Once it was back to the Android screen image, it could be rotated again.

My conclusion: if HDMI doesn't work as expected, screw around with it until it does :)

[New] DoPa v2.7

I've just released AOSP 4.4.4_r2 DoPa v2.7.

The only significant change since v2.6 is that the kernel now supports the German version of the Sero 7 Pro (M470BSG).

I've also released a companion version of PhilZ Recovery which also supports that model (along with all the other international versions). German users should install PhilZ

before

attempting to install the full ROM. If PhilZ boots OK, you shouldn't have any problems installing the DoPa ROM. See the first post for installation instructions.

FWIW... the only reason a user outside Germany might want to install v2.7 is to test whether it is now possible to tether the tablet to your phone via Bluetooth. Previously, the two would connect but the tablet was unable to use the phone's data (internet) connection. This may work now but I have no way to test it.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] doveman:
Thanks for the great, easy to follow instructions. I just updated my Mum's UK Sero 7 Pro no problem.

I had a bit of a scare when the WiFi was totally unable to turn on after installing, in fact the WiFi button was greyed out and stuck on Off (maybe connected to the BT error message, as that appeared when on the initial setup WiFi screen, where it got stuck on Enabling WiFi) but after rebooting that fixed itself thankfully.

Regarding the Gapps packages, I installed nano as advised. Is there any reason not to install the stuff that's under Add-On modules (Google Camera, Google Keyboard) from the Play Store rather than installing the module zips in recovery? Some things like Google Calendar, which are listed in the packages as "replaces stock/AOSP" (the same as Camera and Keyboard), aren't available as Add-On modules so I'd have to install them from the Play Store, which is why I wonder if there's any issue with doing that for Camera and Keyboard, or anything else like Chrome?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] impster:
Hi and thanks again. To upgrade from v2.6 to this new version would I need to upgrade the ROM, nexus 7 spoof AND gapps or just the ROM?

Thanks!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] johnnyrichter:
Just installed v2.7 & PA gapps pico via TWRP(performed wipe of data, cache, dalvik and also formatted). Upgraded from v2.1. Reason for upgrading was to get any fixes/additions in later version and because my tablet had slowed down considerably over the last 6 months and was becoming unbearable. Not sure why since I don't have much installed and really only use it occasionally.

Install went smooth, received a 'bluetooth has stopped' error on first bootup but haven't seen it since. After installing and configuring all my apps, installed xposed, enabling exposed modules, etc I eventually noticed that WiFi was off and would not turn back on. I performed a full reboot and it seems to be working fine now.

Tablet runs like a champ right now. No issues since the WiFi one. Will report back if I find anything else, but at this point I'm happy.

Thanks again for the awesome support on our Sero 7 Pros, dolorespark. :good:

Is this the final/stable version of Kit Kat DoPa now that you're working on the Lollipop versions?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
I think this ROM is feature-complete. If there are any updates, they'll likely be to the kernel rather than Android-proper. I may issue an update to Philz Recovery because I discovered it won't let you reinstall the stock ROM (dumb mistake here).
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gster09:
I know this ROM is no longer the latest and greatest, but I'm happy to report that I finally sorted out the problem with the 2nd partition using Link2SD.

Let me recap by saying that installing that app and trying to use it to move/save apps to a second partition on the external SD would eventually render the S7Pro useless. Since I successfully use the app on several other devices using the same configuration, I am quite familiar with its workings and couldn't figure out what made it stop working on the Sero since it used to work at some point in the past.

Recently, I went back to the drawing board and the only thing I changed was that instead of formatting the 2nd partition as ext4 (like I've always done), I instead formatted it as f2fs using gparted on a Linux machine. Wouldn't you know it? It works beautifully once again! Based on this, and the months I spent trying different things, I can only surmise that my troubles began when I upgraded the Sero to one of the ROMS which included f2fs support. I think that would explain why it worked on DoPa's 2.0/2.1 . My guess is that the inclusion of f2fs in the kernel makes it handle something differently, and it is what probably caused the trouble. In any case, I just wanted to report my findings in case anyone else comes across the same issue.

Thanks for all your work on this tablet with this ROM and with the new Lollipop ROM you've also published. Cheers!

Hello All

Need some help with the performance setting. After a fresh install under performance even though I select 1.5 ghz the max it will take is 1.3 ghz. (gpu does 520 fine) I checked with no frills cpu and the highest listed frequency is 1.3.

I've tried fresh download of the latest 2.7 along with a previous file I had when it was first listed.

Any ideas on how to fix this?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] AzzidReign:
Which version of gapps works for this rom?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Any one that's identified as compatible with Kitkat (Android 4.4x)

As always, I have to ask "did you reboot then retry?. Lots of things are screwed up on the first boot-up after a new install and only resolve themselves after a reboot.

If the problem persists after a reboot, then we have an

entirely

different problem that may require a mod to the kernel. First, though, what country do you live in - or more nearly, where did you buy your Sero 7 Pro?

All these tabs have a "Tegra3" chip but not all Tegra3's are the same: they come in different varieties. For instance, the tablets sold in Australia use a different version than the US models. What's significant here is that each variety requires a slightly different voltage/frequency table in the kernel. The DoPa kernel has extended tables that enable overclocking on the two versions that I know Hisense used. If your tablet has a different chip, then I'll have to add an appropriate table for it.

Exactly which chip your tablet uses appears at the very beginning of the dmesg log. If you think this is the cause of your problems with overclocking, let me know and I'll provide a reliable way to capture this info.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] sinnedone:
Hello Dolorespark, yes I rebooted several times and also tried clearing cache and dalvik. Still no change.

I am in the US, and I purchased the tablet with a broken screen off ebay US to repair my sons tablet with bad usb port.

I isntalled terminal emulator from the play store and ran this command "su -c dmesg > /sdcard/dmesg.log"

Attached is the result. Is this the correct info you need or do I need to go about it another way?

Please let me know and thank you for all your help.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
I'm afraid you waited a bit too long - your log starts 0.119124 seconds after boot and I need to see it from 0.000000 seconds. If you want to try Terminal Emulator again, do it as soon as you possibly can after rebooting - the kernel only has 128k to store its log and then it wraps, overwriting the first entries. Otherwise, if you're set up for ADB, I can describe a method that always works...
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] sinnedone:
Oops, Sorry about that. Didn't know there was a limit on the amount of info the log could hold before it started deleting entries.

So I tried it again as soon as possible after a reboot and attached the results. If this is still too late in the log then please yes let me know what commands I need to run. I don't currently have adb installed but I'm sure a quick search would turn up a "how to" of how to get it up and running.

Thanks again :D
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Just what I needed: you

do

have a different chip! The key is on line 34 of your log; here's a comparison:

yours: cpu_speedo_id = 7, soc_speedo_id = 1, cpu_process_id = 2, core_process_id = 0
mine: cpu_speedo_id = 7, soc_speedo_id = 1, cpu_process_id = 4, core_process_id = 0

If I understand correctly (no guarantee!), after manufacture, each chip is tested for performance and assigned to one of several "bins"- that's the "cpu_process_id" above. For our chips, id '0' requires the highest voltages to achieve a given CPU speed while id '4' requires the lowest. Consequently, there are separate voltage/frequency tables for each variety. I added overclocked versions of those tables for ids '3' (used in the Australian model) and '4' (all others - or so I thought). It looks like I'll have to add one for '2'.

BTW... despite the different chip, you do have the US model ("machine ID 4373" on line 5), not some cast-off they failed to sell in Mongolia :) Your battery, RAM, and MAC addresses are different than most US models but the rest appears to be the same.

Ok Awesome.

I was wondering If I received some mutant tablet that I used for repair lol.

Is there anything else you need from me or is it good with that info?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] doveman:
I'm afraid I'm having a major problem with this ROM, in that if I disable the WiFi I seem to be unable to turn it back on again. I go to the WiFi settings and move the slider to On but nothing happens and if I go back to Home and then back into the settings, the slider is on Off again. I have to reboot to fix this.

EDIT: I should say it doesn't always do this. After rebooting I'm able to disable/enable WiFi no problem but after a couple of days of not using it, when I come back to the tablet it's stopped working and I have to reboot.

I'm also finding the tablet quite laggy and it's quite unresponsive and slow entering my unlock pin and then drawing the icons on the Home screen. I do have it encrypted, so maybe it struggles to cope with that? The only extra apps I've got running are AFWall+ and Avast. I've installed Clean Master to prevent apps loading at boot and to kill apps to free up RAM. I'll try OC'ing the CPU/GPU to 1.5/520. Should I also try changing the Governor and/or I/O Scheduler with No-Frills CPU?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
No that's all. I implemented the fix in the kernel I'm beta testing for Lollipop. I'll back-port it to the Kitkat kernel soon.

I've run into this problem but not lately, so it may be Kitkat-specific. Basically, the upper levels think WiFi is off but the driver is still active. When the upper layer tries to turn it on, the driver says I'm already on - and nothing happens. One possible workaround is to switch to airplane mode to force the driver to turn off. When you exit airplane mode, everything should be in sync and WiFi should turn back on (or so I hope).

This ROM has never been the fastest turtle in the pack but few people have described it as "laggy".

I have to wonder if an antivirus or firewall is really needed on a system whose primary threat vector is malicious apps. It's your choice but you may want to try disabling them temporarily to see if that has any effect. You may also want to confirm that your process killer isn't closing the launcher app - doing so would certainly slow things down when waking up the tablet.

Finally, I wouldn't use overclocking as a way to paper-over problems that shouldn't exist in the first place. Changing the CPU governor won't help much either because it isn't very effective on these Tegra3 systems: the processor spends almost all its time running at either the top speed or the slowest speed, with very little in the middle.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] doveman:
Thanks, that's a usable workaround that's not much hassle, so I'll try that next time it happens.

Wouldn't the antivirus be needed to protect from said 'malicious apps' though? Another reason I use Avast is for the Anti-Theft remote locate/wipe features but maybe the Android Device Manager is sufficient for that, so I'll try removing it.

The firewall I consider quite important though, as it lets me restrict the apps that can use data to a select few (Instant messaging for example) that I need to maintain constant connectivity even when WiFi is disabled. It also allows me to switch to a profile when going out that restricts most apps to the VPN, other than Dolphin Zero which I use to login to public WiFi hotspots where necessary, so that I can be sure nothing leaks over the public WiFi before the VPN connection is established, or in case it goes down without me noticing.

Apex Launcher is in Clean Master's ignore list and that doesn't automatically kill apps anyway, only when manually run. I don't think any of the Xposed modules I've got installed (APM+, GPSNotification, GravityBox, KitKat SD Card Full Access, Phab7, Swap Volume Keys) could be causing slowdown/lag. I didn't have "Keep in Memory" set for Apex though. Setting that does seem to have helped and now the lockscreen comes up as soon as I press the Power button, whereas before it would take several presses or a held press to get it up., and the Home screen shows up without lag once I've entered my PIN. I have uninstalled Avast as well though, so that might be contributing to the improvement.

Actually, having slept/locked the tablet and woken it a few times, it does sometimes still fail to wake when pressing the Power button and I have to try a few times like before, so that problem isn't actually fixed yet, although at least the Home screen does still come up without lag now.

Thanks for the advice about overclocking. I'll forget about trying to use that until I've solved the problems.

I'm gonna take a guess and say the gps problem is from the last stable build of cm. I have cm m5 i believe it is on my phone lg970 and was using gps a couple of days ago for navigation and the signal kept dropping out over and over again. I dont remember having any issues before flashing the stable version instead of a nightly. Just my 2 cents.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Thing is this is AOSP so if the problem exists in Google's code it might also exist in CM, but CM is not the cause of the issue.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
GPS

I've spent a day and a half checking this out: looking at code, logcats, dmesg logs, gps daemon logs, and testing, testing, testing using 3 different ROMs. I tried my AOSP build with a trivial fix taken from CM, and Dave's CM11-m5 and OmniRom builds and got largely the same results. My conclusion is that they're all flaky.

When the GPS was first turned on, the GPS Status app I was using reported 8-11 satellites and got a fix from 6-10 of them within a minute. If I then took the tablet inside so as to lose all the satellites then went back outside, it was a crap-shoot whether it would find enough satellites to get a fix. Even if it did, the fix was very unstable: good for a few seconds, then lost for a much longer period with reported satellites varying greatly. The best way to get a fix again was simply to turn off GPS then turn it back on.

The GPS code in all 3 ROMs I tested is (almost) identical and acts primarily an interface between apps and the lower-level software that actually does the work. The real functionality is contained in binaries taken from the stock ROM - and all 3 use the same files. If GPS performance on the Sero7Pro is poor, I don't think we can blame any of the code we have access to. Instead, I'd have to blame those blobs, or just low-grade hardware.

I'd love to be proven wrong. If someone can identify an S7P ROM whose GPS is rock-solid (at at least really good compared to the others), please let me know so I can investigate.

This looks more like a WiFi router/modem problem than something wrong with the tablet. Another tablet I had used to saturate the router with requests and overwhelm it, killing all connections. In this case, Music is requesting lots of cover art at the same time, along with whatever you wanted to listen to. If/when this happens again, try power-cycling your router (and modem, if appropriate) and see if that doesn't fix the problem.

The GPS shutdown problem is very reminiscent of the Nexus 7. It had the exact same issue when it first came out. It would work for about 10 minutes and then completely shut down until it was rebooted. A subsequently released update from Google fixed it. Perhaps the original code, not the patched, is what is in AOSP.

So is this a good daily driver now then? Seems like most everything seems to be working well besides the GPS issue. I rarely use the GPS on my tablet anyway.. Usually use my phone for navigation.

Question: What is the best way to leverage space on the MicroSD to (as seamlessly as possible) allow for large game installs? Is FolderMount really the best option? It's been working pretty well for me with DoPa v1.1, but it also is very manual and once you get too much space used up in local storage, you can't do much, since an app has to be installed locally first and then moved to SD with Folder Mount. Wondering if there is a better way to do it by formatting and somehow mounting a parition on the SD during startup. Any thoughts on that?

I've not updated my Sero 7 Pro in many months since loading DoPa v1.1 a while back, but feeling a bit itchy about it today and thinking of wiping and upgrading. I got a new Drone controller so wanting to make it a good setup for gaming. Any suggestions on the best way to leverage my SD card as seamlessly as possible for loading up games?

Thanks!
