missing for a week, a lot of work. I continue work with the p900.

I managed to localize the kernel crash from youtube, I was sure about omx problem, but look like crash in the sound part in the kernel. I made fast fix to fix crash, but I think I need somehow backport sound part from more fresh device. Look like somehow sound mechanism broken in the kernel in the 17.1
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Thx for your enthusiasm for our device.

Don't know if it helps but mine (still on 20200825) has no probs with multimedia.

Radiodroid and VLC working fine.

But sudden reboots even when just surfing.

Firefox working or not? I don't care any longer ?

Hi, Thank you very much for your work. I have a question.

How do we turn off the pen pointer? It bothers me as I use it mostly for drawing.
[Galaxy Note Pro 12.2 Android Development] achint.andro:
Thanks much to give new life to old device.

Flashed , looks very clean , since I am coming from Lollipop , I guess. However as others have mentioned , Tab reboots whenever I try to launch anything to do with video. like youtube, any games etc.
[Galaxy Note Pro 12.2 Android Development] jmase:
What drawing app do you use? When I try just scrolling the homescreen with the S-pen the tablet reboots.
[Galaxy Note Pro 12.2 Android Development] cmlmstf:
I have the same problem with my device :(
[Galaxy Note Pro 12.2 Android Development] Valera1978:
hi all

new version:

- small kernel update

- rewrite audio part (I spent a week looking for the reason for the crashes in the youtube, I was 100% sure that the problems were in omx libs or in the our mali, but the real reason was in the sound - wrong konfig)
[Galaxy Note Pro 12.2 Android Development] Adam1422:
(full wipe + twrp 3.4.0.0)

no magisk

latest build added today

Gapps ARM, 10, standard

flashed and getting stuck on lineage screen - been sitting for 15 minutes plus.

Tried a reboot into recovery and flashed again and stuck in same spot...any ideas?

Thanks in advance
[Galaxy Note Pro 12.2 Android Development] Valera1978:
sorry, something went very wrong.

rebuild again, now all should work.
[Galaxy Note Pro 12.2 Android Development] Jerussel:
Thank you so much

All working good on the new build (4)

I did have hiccups with installation. Somehow during pre flash wipe, TWRP had reset its modification permission without any notification. It wasn't til 3rd attempt that I was asked to give permission. Then flash was successful.

Thank you Valera, is there a way to buy you a beer?

Video now perfect. Sound much improved than on 14.1 Thanks again

Keith.
[Galaxy Note Pro 12.2 Android Development] yminale:
This is the most stable build yet

1. 5ghz wireless works now

2. Youtube works

3. Ok, google can be installed with the lineageos fix

4 Security tickets working

Hi. I have a model(sm-p900 galaxy note pro 12.2) and want to re-operate it. too slow, can't charge fast,, etc. I ordered a new battery and searched some information. Still, I didn't understand exactly how to do it. Is there anyone teach me how to do it? what kind of file do i have to download and everything....:crying::crying::crying:
[Galaxy Note Pro 12.2 Android Development] jmase:
Build 4:

When flashing I get a error message (Cannot mount) but it still flashes.

Using S-pen works somewhat better, I can write/draw in Squid without any problem, tried for a few minutes

but when I use the s-pen to swipe on the homescreen or in other apps the tablet hangs.

It takes time for my background bitmap to draw every time I get back to the desktop from screen off, the bitmap (jpeg) is 600 bytes big.

No camera app! (is it intentional since not working?)

Mozilla not working :(
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Afaik fast charge is not implemented anyhow, at least never noticed any on mine.

Do what? Change battery?

Which OS does it have?

If you want to flash custom ROM look for how-to TWRP first cause that's the base you need for whatever ROM you want to flash.
[Galaxy Note Pro 12.2 Android Development] rhricik447:
Search functions can be your friend!

For your battery from Youtube:

https://m.youtube.com/watch?v=VeSG0hHpAG8

Update your tablet to last official Samsung Android update for the tablet (very important!! It contains a bootloader update that these newer ROMs require. If you don't do this step, your new rom flash won't boot! )

Find and install Odin on your PC, then

For TWRP:

http://www.youtube.com/watch?v=RIvWVS_Rkxo

Once TWRP is correctly installed, you can install any custom rom for v1awifi (this is the unique board name that identifies the Samsung Galaxy Note Pro 12.2 device) like the ones listed here in this forum. If at all possible, use the original USB cable that came with the device - less chance of probems. If you don't have it, use a good quality usb 3 cable.

I need a stable operating system so I use an older version ROM (14.1), but I know these developers will get 17.1 hammered out quickly and I'm excited.

These devices were released before there were any fastcharge standards, so they will take hours to charge from a low battery, that's just life in the old lane! Make sure your charger has enough power - I use one that charges at 5.1v and 2.1 amps (12 watts) and have no problems.

This forum has a wealth of knowledge, search for your answers. These are old tablets, so any questions you may have were already asked and answered somewhere on this forum. When set up properly, these are still really nice tablets. Remember to read everything

twice

so that you only need to do it

once

! Good luck!
[Galaxy Note Pro 12.2 Android Development] thools60:
Thanks Valera. Had almost forgot my old note pro. Saw this and decided to get a new battery (22 bucks in sweden) and give it a go. Works great. Forgot about this gorgeous screen and its like ive bought a brand new tablet. The rom works pretty snappy and battery is really good. You made my day. THANKS!:laugh:

Edit: I too experience the Firefox issue. Chrome based browsers, no problems

The inoperable front and rear facing cameras are the biggest problems with the 9/10 build. The rest works. Hopefully future builds with have the camera working.

Feedback to 20200910:

Clean Flash, GApps, TWRP 3.4

- Audio OK

- Youtube and other multimedia OK

- No random reboots while using S-Pen

- No Front/Rear Camera Working (not an issue).

- Most Stable Build so far

- "Laggy": at least for me, if you type "too fast" using a keyboard (bluetooth official keyboard in my case), the system reboots.

It happened 2 times for me while trying to write this feedback.

Thank you Valera. Will be testing any future update.
[Galaxy Note Pro 12.2 Android Development] MSgtTUSMC:
Hi! New to the site and flashing Lineage ROMS.

I must say with a heartfelt thank you for this latest build!!!!

I was fixing to get rid of my SM-P900 tablet due to many of the apps I used not supported in the old OEM android version anymore.

The flash went extremely smooth using the lastest TWRP version. I also installed the GAPPS stock with no issues.

This build is running pretty smooth for me. Battery life is good.

I only have a few issues:

Two reboots due to the stylus issues others are having when using it on the home page.

Flashlight and cameras not working

5G networks not visible. Only able to use 2.4 networks. Was able to use 5G with OEM build.

Other than these. I have had no issues or crashes!

Again extemely grateful for all your efforts!! I am so glad I came here and tired your build instead of trashing my tablet!
[Galaxy Note Pro 12.2 Android Development] dcarvil:
If you search the 14.1 thread (https://xdaforums.com/galaxy-note-p...-7-1-xsm-p900-unofficial-cyanogenmod-t3524788) for P-901, you will see that ROM will not work on the P-901 without modification. I would assume it is the same for this ROM, but that is just my guess. You could take a TWRP backup of your current setup, then restore it if this ROM does not work. If you do that, please report back here. I am sure there are others who have the same question.
[Galaxy Note Pro 12.2 Android Development] cmlmstf:
If the following features can be added, this rom will be no different from official rom, moreover with android 10.

When we use s-pen, we should be able to write when our hand touches screen at the same time, and We should be able to turn off the pen pointer.

Thank you very much again for the rom.

How can I modify it to Be installed on the P-901 and I will test it and revert Back with the outcome
[Galaxy Note Pro 12.2 Android Development] f1b0n4cc1:
i asked same question about sm-p902 and did not receive answer. i wonder if it is possible to install this to 3g version and what i need to activate sim functionality.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
I'm not that well knowing, but as your versions have both mobile data I assume it might be more reasonable to ask in the P905 (LTE) sub forum than in the purely Wi-Fi thread.
[Galaxy Note Pro 12.2 Android Development] f1b0n4cc1:
if i am not wrong sm-p905 has snapdragon cpu and sm-p900/ p901 and p902 use exynos. So it looks possible to install sm-p900 package to sm-p901 or sm-p902 while forget about mobile data.

I was using lineage sm-p901 appropriate packet in my sm-p902 by editing update file on data and re-zip it so it does not stuck on version check. I wonder if it is possible to apply sp-900 in to mobile data enabled devices and upgrade to enable modem with extra software or not.

I hope someone can answer for this. Thanks for your answer
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
You're right with the chip.

Didn't think of that.
[Galaxy Note Pro 12.2 Android Development] jodev:
Yes. I can confirm this issue on my sm-901 too. Touch and pen works individually. But if i rest my hand on the screen and use the pen, the system crashes. Palm rejection not working and leads to crash.
[Galaxy Note Pro 12.2 Android Development] jehu17:
Hello Valera, got your firmware installed yesterday with Gapps nano and latest TWRP 3400. Found 2 problems so far

1. Youtube works very slow, frame rate is lagging. Tried Geekbench 5.2, it makes 171/490 points (single/multi core), which is OK, not sure what's the problem.

2. Occasional restarts, couldn't link to any app.
[Galaxy Note Pro 12.2 Android Development] expire_meter:
First Time

I have the P900 and it has become too slow to do just about anything. Story you've all heard a 1000 times now. I got it so I could have books, basic internet, drawing, video and some basic gaming (board game style) in a portable format. It was an expensive bit of equipment that should still be just fine for the above if not for Samsung. . . .

Would this be a good set up then? I am new to all of this. I am a linux user and fairly tech savy but when it comes to mobile I haven't really gotten into customization yet.
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
I would very much recommend installing a custom ROM on your P900, it will breath new life into it. However if it's your first time, you probably shouldn't start off with a ROM like this which is in the development and testing stage. I would suggest you either wait until a properly stable build of this ROM is ready, or go for a stable build of an older one, such as Lineage OS 14.1:

[Galaxy Note Pro 12.2 Android Development] phigan:
I found this out the hard way. After flashing, this rom wouldn't boot.. I thought maybe I needed to go back a version of TWRP or something, so downgraded that.. didn't help. When the other Lineage rom also failed, I was going to try a Samsung-based rom like this one, but then I noticed the note about the bootloader update. Flashing that made both Lineage roms (17.1 and 14.1) boot just fine. Thought I'd share in case anyone comes straight to this from 4.4 or whatever I was on before.

I'm running Resurrection Remix 5.8.5 by Schrolli. Does this mean I have the new boot loader?
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Custom ROMs don't change Bootloaders.

You have the latest one (very likely I think it's needed for Schrolli's ROM), if you came from latest stock.

Check with PhoneInfo (needs root).
[Galaxy Note Pro 12.2 Android Development] mikey williams:
Thanks. I’ll check.

Hi to all,

just to inform you that I tried your build on an existing "Resurrection Remix 5.8.5" (Lineage based) and It's working great (but not the camera as you already know). I just lost a couple of thing but this enable me to be operative in 15 minutes. Great ! Thanks and continue with this job, very nice.

Coming from latest LOS 14.1.

Made a clean install with data format, BitGapps and Magisk.

Fast restart and seems ok so far.

Trying to use AFWall+ gives "error applying iptable rules".

Although this message came and it couldn't be enabled, internet access got totally blocked until I uninstalled it.

It's fully working with LOS17 on T325 so I don't know what's the cause.

And yes it has storage access granted plus su rights.

Any hints?

Latest build

open-gapps arm 10.0 mini

twrp 3.4.0.0

All apps close after a few seconds. They stay open as long as I am touching screen in app but close after a few idle seconds. Any ideas why?

Found loose connector inside. Changed battery and something came loose. Problem solved.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Same problem if no gapps installed?

On LOS17 I'm having problems with opengapps (only tried pico) but none with Bitgapps.
[Galaxy Note Pro 12.2 Android Development] dadecamp:
Yes. After full wipe and reflash, all apps close after a few seconds.

More info: I had battery issue with flickering screen which caused system crash. After replacing battery I installed this rom and noticed this issue. I tried installing without gapps. Same thing happening. Tried lineageos 14.1 and same thing happens with it too. Could it be hardware issue? Point me in right direction please.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
To make sure it's not LOS related I'd flash stock ROM.

If same things happen it's the hardware I suppose.

Did you reopen it and checked all connectors already?
[Galaxy Note Pro 12.2 Android Development] dadecamp:
I just got done checking inside and found a small loose connector :p

everything seems ok. Will reflash this ROM again and I think it will work fine. Thanks

5 GHz band not detected.

Hi Valera1978,

thanks for the new lineage 17.1. it looks awesome and its definitely faster than the lineage 14.1. However I am having one issue and that is my WIFI wont detect the 5hz band, it only detects the 2.4hz. I tried all 4 versions you posted and still no luck. I am now back to using lineage 14.1 on SM-p900 and my Wi-Fi now detects the 5hz band. Any possible solutions where I could make WIFI detect the 5hz on the new lineage 17.1?
[Galaxy Note Pro 12.2 Android Development] westwallpoma:
Nice work. Only issue I've had so far is connecting to my mesh wifi.

Disabling "Fast Roaming" on my mesh solved the problem (and I have enabled it again now my SMP900 has connected).
[Galaxy Note Pro 12.2 Android Development] nsiti:
Hi, I'd like to add to your wifi connectivity diagnosis. The issue on my end was that the 802.11b broadcast had to be enabled on the wlan in order for the tablet to connect to my wifi. Since this protocol is known to slow down the 2.4 Ghz band, I created a second wlan on my network for "old faithful" Galaxy Note Pro 12.2. I did disable fast roaming on this slower wlan. Cheers.

Valera, thank you for this ROM !

I wanted to say thank you for the development of this ROM.

I installed it yesterday and set up most of my apps. I noticed that some of the sign-in dialogue boxes in some apps were bugged (couldn't see the place to enter the user/pass) making it difficult to log-in, but with some trial and error, managed to do it. For example Skype, and Outlook, as well as Washington Post (IIRC).

I had some issues with the wiif not connecting (see my post above) but worked around that.

I would love a working camera, whenever you can get around to it. :)

Cheers!

I'm trying to update from 14.1, and TWRP won't let me update, says this version is not for my tablet. Any idea why? I downloaded the latest 20200910 build and appropriate gapps. TWRP says E7.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Which TWRP are you using?

Afaik it works with 3.4.0
[Galaxy Note Pro 12.2 Android Development] Sheeptar:
TWRP 3.0.2-0. I tried updating TWRP within TWRP itself, downloaded the latest image but am getting a weird error opening "not a directory" error. :(
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
How did you upgrade?

Flashing image, or app or something else?
[Galaxy Note Pro 12.2 Android Development] Sheeptar:
Flashing image in recovery.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
And of course rebooted into recovery again?

So from 3.0.2 directly to 3.4.?

Perhaps better with steps in between?
[Galaxy Note Pro 12.2 Android Development] Sheeptar:
I don't know if I need steps in between. The versions arent that old. I'll try flasing in ODIN.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
So you're not flashing image in recovery, but .tar in Odin.

You can flash .img in TWRP itself if the version is not to old.

If latter use steps in between with .zip until you've reached a version which can use .img.
[Galaxy Note Pro 12.2 Android Development] Sheeptar:
I didn't know that my TWRP was too old to flash itself, since it had the option to flash with image. I updated TWRP now with ODIN and it flashed this ROM without problems. Thank you.

Will check it out a bit then decide if I will keep it or move from lineage back to latest stock marshmallow. It's old but official samsung.

Did you guys get Firefox working? I'm using the 14.1 version and just noticed this so thinking about upgrading.
[Galaxy Note Pro 12.2 Android Development] Rok7310:
I am still hesitating to upgrade, because of the missing camera support. In the meantime, did anybody compare the responsiveness of the new Android 10 with Android 7 on P900 ? Is the new one slower, more hungry ?
[Galaxy Note Pro 12.2 Android Development] westwallpoma:
No real evidence, but battery drain seems higher on 10, plus video playback suffered from what I suspect is non hardware decoding (apologies to the developer if this is not the case). The UI is very snappy (more so than 14.1) and benefits from Android 10 optimisation.

I reverted because a lot of my plex content is hevc, and was impossible to playback on this version. Outwith this, it's a fantastic piece of work from the developer, and I've no doubt it will become our de facto daily driver in the very near future.
[Galaxy Note Pro 12.2 Android Development] Stuggy:
I installed this and am enjoying the update.

For me:

Battery seems to be used faster. Maybe Android 10 vs 7?

I have to set the screen brightness higher than with the equivalent Android 7 rom.

Is video not hardware rendered? From reading posts above.

I've had a few reboots while just web browsing but overall stable.
[Galaxy Note Pro 12.2 Android Development] nsiti:
I can also confirm several random reboots while browsing (using Bromite) yesterday.
