You are correct, the OMS subsystem was officially added to the repos around the first of the month. Substratum does work from the Play Store, but I'll integrate it into the system ROM during the next build. I've been testing the 5.8.2 build since yesterday, but apparently they rolled the 7.1.1_r21 stuff in since I last did a repo sync on Thursday evening...hence I'll need to repo sync AGAIN.

For those interested, for some reason, Gello (shows as Browser) and Gallery are still getting FC on startup; I'm going to download a pre-built Gello to see if it at least fixes that problem. I think Gallery may be in some way related to either the Camera issue or OpenGL ES (since we're still shimmed to make ES 3.0 work; Qualcomm will NOT be updating the code to ES 3.1/Vulkan requirements for official Nougat).
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] TERM1NATOR:
I use RR 5.8.2 on various devices as mentioned before and if my memory serves me correctly browser fc on those devices too when going through the initial setup if that's what you mean by startup. or does it fc every time you restart the tablet?

Does Gello have to be included in the build? is it needed I am only asking as I do not know I am not the expert, but if it was not included then maybe that would solve a problem.

Also could you give me a little more info on the gallery fc, does it happen only once on startup or does it happen all the time? is the gallery app usable?

Many thanks for your hard work.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Airtioteclint:
Gallery only fc once on initial bootup after a fresh install for me. Just hit ok and it works as normal. it's not even worth mentioning really.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] tiritibambix:
Thank you very much for that wonderfull ROM :D

I now run it on 3 different devices :laugh:

Hello developer i just installed your rom and so far it looks beautiful and im loving it I haven't come across any problem not an expert in roms so i cant really tell if something is going wrong. Also thank you for enabling substratum theme into your rom it makes my tablet look soooooo pretty!!. Thank you and looking forward towards more updates. :good::good::good: :o:o:o

hi developer i was wondering is there a way to uninstall the camera app without causing system issues or do i need to have it install. I was wondering cause when i go into my photos i be going into camera by accident giving me bunches of errors. Im ok without having the camera app cause i dont use it anyway.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] tiritibambix:
Once again , thank you for this amazing job :)

But how can I have a working camera (and torchlight) ?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
New version up on the first page; fixes the Gallery and Browser FC issues, incorporates Feb security patches. Camera still broken, logcat shows OpenGL ES errors, I haven't found a way to bypass that yet.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
You can try to freeze it in Titanium Backup, but honestly, I haven't tested that yet, so I don't know what will happen if you do that. You can't disable it from Settings/Apps.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] DowntownRDB:
[MENTION=7104775]rnwalker7[/MENTION] Thanks for the update to the ROM. This update definitely fixed the Browser and Gallery FC issues. I have dealt with OpenGL ES errors on a ROM I was developing for the old HTC EVO 3D and they are a bear to track down and fix. Sometimes one fix creates other function errors so best of luck in getting the Camera App working. I don't think any other CM based Nougat ROMS have Camera fixed yet either so you are in good company.

I know your schedule is very busy, so again, many thanks for the latest update.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] duckredbeard:
Got a big issue with this device running a previous build of this ROM. Here we go…

Random reboots early after each boot. Notification drawer says no notifications even when there are some (Tasker is running), quick settings will not expand. Tablet will not charge when on or off. Plugged in (off state) overnight had battery go from 26 to 12%. No indication of charging while booted to TWRP.

EDIT: recents button also not responding. Hardware or navbar. Or the back button.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Airtioteclint:
FYI for anybody deleting any system apps on feb 16 build needs to boot into recovery and wipe caches before reboot or you'll end up in a never ending bootscreen.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rholm:
It took a long time for me on the initial boot. It was more than 10 minutes.

Also, TB couldn't read my apps. I had to restore from Google. I am up now. Seems stable and fast.

Cheers,

Rich

Many thanks for the developer, amazing job !
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] ruahusker:
Did subsequent boots go okay? It is taking me approximately 25 minutes to boot each time after this latest build. I have flashed cache and dalvik cache with no improvement. Other than this boot issue I am amazed at the stability and speed of this!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] brunolopes446:
It also takes me around 15 minutes for a simple reboot. Apart from that, seems stable and fast for now. (26 Febr build)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] digiabyss:
I am also having this same 15 min boot issue. The initial boot was only 5 mins. I only installed a couple apps for use with my drone. The rom is super responsive and appears stable except if you need to restart!! Hats off to the developer for your dedicated work but is their a workaround for these excessive boot times?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
For those experiencing long reboot times...did you do a full system wipe (format /data, including /data/media, /system, etc...leaving only the SD card untouched)? I haven't had these issues (2-3 minute reboot time), and this was the procedure I followed. I just want to know if others did the same and have this issue.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] DowntownRDB:
[MENTION=7104775]rnwalker7[/MENTION] Per your installation instructions in Post 1 I did, and always do, a complete Factory reset (wipe system/data/cache/format data). It takes my tablet 2 mins, 15 seconds to reboot. Rebooted twice just to ensure I was still getting fast reboots.

I have never been a fan of "dirty" flashing. From reading numerous threads it appears that over 90% of issues are caused by NOT clean flashing. I would rather take the extra time after a clean install to download the apps I use from Play Store than spend 4-5 times the amount of time troubleshooting issues left behind from a dirty flash. Just my 2 cents worth.

Have a great day all and I hope you get your rebooting issues resolved quickly.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] innocentus:
i dit a dirty flash but only 2-3 times took long time to boot after that has gone strange
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] tiritibambix:
Loving the ROM so far.

But how can I have a working camera (and torchlight)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] robhug:
I reverted back to the previous, it happened a very strange thing, first lot of boot problem and then when I rebooted to TWRP to downgrade the the previous build, TWRP give me the message to swipe to allow modification (I swipe) and then fail to wip mount or install anything and I have no choice to format data, hopefully I have a backup on SD card, it's like if the latest build have encrypted everything.. I recommend to stay on the previous version, I have no problems with it
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] digiabyss:
I did perform a full wipe including format of data partition. The first boot was approx 5 mins. Subsequent boots have been around 15 mins. I will go through the wipe and installation process again to see if maybe I had a bad wipe. I should probably check my TWRP version as well. If I recall I havent updated it for quite a while.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
As I mentioned before, the camera (and thus, the torchlight) are going to require serious debugging. It all boils down to Qualcomm deciding to abandon the MSM8974 (which our SD800 is based on) with OpenGL ES/Vulkan upgrades. It takes a lot of baling wire and duct tape to hold our devices together.

I'm not sure if crpalmer is working on our device much these days, and I don't think phoval has done much with it since Nougat first came out. My free time is limited as well, and I'm no hardware expert, but I do have a few ideas on tweaking the code and/or updating the wrapper from looking at the Github commits, but it's going to be a lot of trial and error. Fortunately after this week, I won't need my tablet for school for a while.

TL;DR - Don't expect anything soon.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] tiritibambix:
I'm feeling really sad right now.

Thanks for your answer tho ^^
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] innocentus:
so on nougat nothing new will come like camera so if i flash now your latest 5.7.4 should work good no ?i really miss the camera but performance was nougat better...i should sell it but there is nothing else to buy feelsbadman thx for your support
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] drk65:
Decided on this being my first ROM after finally Rooting and installing TWRP on my Pro 8.4 this weekend. My experience has been similar to those reported by others with lengthy boot times. My install was initiated only after a thorough and complete Wipe, and as mentioned above, this is the first and only ROM I've installed after Root/TWRP. I'd estimate each of my reboots to be in the area of 10-15 minutes. During one of the first long boot times, I searched this forum to determine if this was an issue, as I thought I was in trouble seeing the boot logo spinning over and over again. However, my device does eventually boot... and that's when the fun begins.

Thus far, after boot completes, I have nothing but good things to say about this ROM. It's most definitely breathed new life into my previously Stock KK Tab Pro 8.4. The device now works better in virtually every way (other than Camera & Torch, which I understood going in), especially with regard to speed, responsiveness, and standby battery life (too early to comment on SOT).

It would be great if the boot time can be addressed and somehow reduced. However, until then, I'll simply schedule reboots for convenient times when I know I won't be needing my device for a while.

Sincere thanks for this great work... and for my "new" tablet! :good:
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] DowntownRDB:
[MENTION=462637]drk65[/MENTION] Just a quick question. When you say you did a thorough and complete Wipe did you also do a Format Data in TWRP? In the Android OS it sometimes appears that wipe data and format data are not the same thing. My factory reset is comprised of wipe system, wipe dalvik, wipe cache, wipe data and then Format data. I just rebooted my tablet and it only took a little over 2 minutes. I'm on 20170226 ROM update and using Open GApps Arm 7.1 micro 20170302.

I know our tablets are supposed to be alike but sometimes I think different brand components are used internally by the manufacturer and that could be what causes some tablets to have issues and others are not effected.

I agree 100% that [MENTION=7104775]rnwalker7[/MENTION] has done a fantastic job with this RR for our tablets and mine has never better or smoother. I had to replace my battery about 3 months ago as it finally would not take a new charge. With this ROM and new battery I get great SOT.

I hope you get your long reboot issues resolved quickly as 10-15 minute reboots are never fun. Have a great day.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Ellobo24:
So im having looooonngggg reboots. I did a clean flash, i even deleted the memory data of the tablet.. It takes like 10min or so to reboot completely.. Can someone help me out please??
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
For those having long reboot times...I haven't been able to recreate the issue. But I'll attempt a newer build this weekend, after syncing with latest sources, to see if that helps some of y'all. However, I need y'all to do the following:

- Format the system, data, internal storage, cache, and Dalvik

- Install from SD card

And see if that helps. There have been a LOT of changes between CM and LineageOS, and frankly, some of those changes don't play well together.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] loperdwb:
- Format the system, data, internal storage, cache, and Dalvik

- Install from SD card

Using TWRP 3.0.3-0 and the latest rom and open gapps micro and doing a factory reset I am encountering the long boot times. Could you give me instructions on how to format system, data, internal storage, cache and dalvik in twrp? I don't see how to do that.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] DowntownRDB:
[MENTION=5463173]loperdwb[/MENTION] The latest official version of TWRP that I can find is 3.0.2-0

I can't answer for [MENTION=7104775]rnwalker7[/MENTION] but below is how I do it and have always had great success.

Download and check MD5s on ROM and GApps to my PC. Once I copy them to my tablet I recheck MD5s to ensure no issues occurred with file during copy process from PC to tablet.

Boot into TWRP

1 - touch Wipe

2 - touch Advanced Wipe

3 - select Dalvik/ART Cache, System, Data, Internal Storage and Cache (CAUTION: Don't select Micro SDCard)

4 - swipe to wipe above selection partitions (some developers recommend repeating steps 3 and 4 two times, but I do one)

5 - when swipe completes successfully go back to Wipe screen and touch Format Data in lower right hand corner

6 - Type yes to confirm/continue formatting of data

7 - At this point you are ready to clean flash. I flash ROM and GApps in 2 separate steps vice back to back in one flash.

8 - Flash GApps (I use Open GApps Arm 7.1 micro 20170302)

9 - Reboot system

This could be the same process that you currently use, except maybe the FORMAT data in addition to wiping it. If you already do 1-9 above then I'm out of ideas as to what is causing yours (and others) long reboots compared to my normal 2 minute reboot. I truly hope you get that issue resolved. If not I'm sure [MENTION=778084]rnwalker[/MENTION] will release a new build after syncing sources again as soon as his busy schedule permits.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Kippy51:
Just for the heck of it I clean installed latest build; formatted everything I could in TWRP and just installed ROM and pico Gapps. First boot 15 minutes .... Flashed an update.zip from TiBu with just 5 apps I always use (TiBu, Nova, Couple of file managers). Boot time 15 minutes ....

Edit: actually it's already spinning for around 20 minutes ... Think I'am gonna reboot manually!

Edit2: pressed powerbutton 'till reboot and now it took 5 minutes
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] duckredbeard:
Wow… so I am not the only one! I have had only one boot since initial boot. I will have to power off charge overnight to make sure it has enough for a full boot.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
So...ran a new build this evening, and...now it takes me 15 minutes to reboot. But now that I can recreate the error, I can pull an ADB logcat and find out what's going on. Before, I couldn't, since I obviously wasn't having the problem. But for those who are already having reboot issues, I can post the latest download, since it does have the March security patches.

FYI to all...if you're having trouble and others aren't, pull a logcat and send it to me.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] duckredbeard:
Wonder if Chainfire's LiveBoot app would help troubleshoot a loooooooong boot. It replaces or overlays the boot animation with a logcat, live as it happens. Could be helpful, but I'm not interested in watching it for 38 minutes tonight.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] pilotbob3:
Count me in on the looong boot times. Anywhere from 5 minutes to 30 minutes for me.

Did an absolutely clean install and deleted everything.

Other than that, and the camera :) this is a GREAT ROM!!!

The long boot times are strange. I have one T320 that has taken at least 20 minutes to boot the 2/26 build. It does seem to work fine afterwards.

I just got a newer one that I installed the 2/26 build and it booted in 5 miinutes. I did just the ROM and then GAPPS after a boot. Neither took very long.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] tiritibambix:

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rnwalker7:
So...food for thought...do y'all want me to try and do an updated 5.7.4 build with the new Lineage sources? At least it has the potential of being stable, plus having latest security updates...

Yes from me.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Kippy51:
Because of huge battery drain issues on the last couple of builds, I decided to restore an old 5.7.4 backup I still had ... I'd forgotten how simple life was back then! Everything works as it should. So yes, I support [MENTION=7104775]rnwalker7[/MENTION]'s idea in post #345!

YES! Would love to upgrade my tablet to a stable version with working camera. Right now, can't upgrade to RR here due to non-working camera. So I am now stuck on CM 11-M12. It been very stable for me and have no rush for an upgrade. But it has been lagging here lately and I think its due to gapps getting way too bloated in the background. I'me sure doing a fresh start via doing an upgrade to RR will help out by elementing a lot of old cruft by using this tablet a few hours every day for the past few years.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] duckredbeard:
I would be all for the updated 5.7.4 build. The last 3 ROMs I have tried have been plagued with issues. I am getting random reboots (on each ROM) so often that I wince with each app opening. Not going to blame the ROMs, as it happens with all of them. I am going to have to do a full wipe/format of all, including internal. Maybe the issue is too many TiBu restores. I gotta try something different on the next flash.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] yojalata:
Whenever I go to a ROM that's not 4.2.2 the tablet charges slowly can't find why.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] rholm:
Have you ever reseated your battery connection?

Cheers,

Rich
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] yojalata:
Well it's not the original battery so yeah, and like i said it charges fine just by going back to 4.2.2. so..kernel maybe? I don't know what else to try at this point besides letting it go or staying at 4.2.2 like ive been.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Kippy51:
But does it say on the lockscreen that it charges slowly or is it really charging at a lower rate (checked with Ampere-app or so)?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] yojalata:
Yeah it says charging slowly and it does charge slower using charges that work fine on 4.2.2 its weird.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Kippy51:
Well, that it says 'slow charging' is normal on all N-ROMs. It's ment for phones that support fast charging, but as far as I know this tablet doesn't. That's why you see that. On my S3 and S4 phones and 10" tablet it's the same. With original wall charger and Anker cable (better than stock) my tablet charges now with 600 mA/h, but I don't know what the official values are ....

Edit: and the fuller it gets, the slower it charges.
