I have p901 which is similar to p900 except it have 3g modem, had the same problem of wifi drops and not turning on + bt problems, it might be the region of the device that have different wifi firmware or idk, try to extract the modem.bin from official .tar.md5 of your regional 5.0.2 touchwiz android image and then flash it to CP on latest Odin, I did this and it fixed the wifi drop and firmware problem on lineage 17, but still system gets laggy and slow, but at least connection is stable.

For this reason I might reflash my old touchwiz which didn't have the exact problem.

also if you want to do this please get a nandroid backup of your modem partition on twrp, so if it didn't work for you, there could be a way to fix it.

Update: found a better solution, there is an app called "Disable WiFi Power Saver S7 ROOT" that do the same thing with service number in touchwiz call ( *#0011#* ) in other roms, just install and turn off the wifi power saving mode and there will be no wifi drops, so it's a voltage drop, some chipsets can't handle power saving mode like other, so this could fix that.

Hi, I've successfully flashed the lineage 17.1 image to SM-P900 but I didn't find any settings to setup my spen. Is there any possibilities to do it?
[Galaxy Note Pro 12.2 Android Development] kolonet:
This build has no palm rejection. I couldn't use it for drawing purposes

I installed it then I revert back to that good old 14.1.

I read the talk on this topic and it seems that @shardsx found a way to fix that palm rejection issue months ago.

So if it is working, why don't we have that in the latest build?

@Valera1978 can you please fix this palm rejection issue in the upcoming build?
[Galaxy Note Pro 12.2 Android Development] mrhbit:
Hello

installed the latest rom and be happy so far. Camera not working, ok, and Infrared seems also be dead.

But all other things are fine, Pen works.

Update: using the PEN causes after some minutes a crash (black screen)

Just installed this on a sm-p900 WiFi version. Using the s pen keeps crashing. Doesn't seem to like Samsung notes, Samsung account or Samsung files. Span crashes squib too. I can type in notes and squib. Battery use seems to be high too. I'm rooted using computer launcher with poco theme. Adw was way to laggy version 1.x and adw 2.0 kept giving permission to import errors. Any idea. I was on rooted 5..x then went to 14.1 then 17.1 wiped each time

[Galaxy Note Pro 12.2 Android Development] bmwdroid:
You did "Format Data" didn't you?

Try either OpenGApps pico or Bitgapps ARM.

The rest of Google stuff which is not included can be installed afterwards.

Hello

I have installed this OS and stucked at Samsung logo. I spent 2 days on it to fix it but its driving me crazy :D

What I tried:

Different twrp versions

Different lineage versions

Other roms / backup giving same bootloop issue

Flashed lollipop BL update via odin

Battery out for a minute and chache clear after

The only rom I managed to work is a cyanogenmod by Valera Cyanogen 12.1 Xda

I hope someone have a solution for me. Thanks
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
Apologies if I've misunderstood, but the way you've written that down, it sounds like you tried flashing the Lollipop bootloader as a last resort? You needed to update that first before attempting to flash anything newer than CM 12.1.

I'm thinking you'll likely succeed if you start over from scratch, go right back to stock firmware. Use Odin to flash the most up to date stock firmware, which should also flash the most up to date bootloader. Then flash the most up to date version of TWRP. Then use TWRP to format everything, then flash the ROM and GAPPS.

The fact that CM 12.1 worked but nothing else did strongly suggests that the bootloader was not up to date.
[Galaxy Note Pro 12.2 Android Development] burnshroom:

Does anyone have a LOS 17.1 build with the s-pen palm rejection fix for sm-p900? There is one on the sm-p905 forum, was wondering if maybe someone got around to using the same fixes for the p900.
[Galaxy Note Pro 12.2 Android Development] f.depuydt:
Thanks for keeping this Tablet alive and usable!

I've tried both your april 2021 and december 2020 ROMS, both boots without issues. But sadly I can't connect to my WiFi network as the authentication is aborted by the tablet (tried different WPA version but no success, OpenWRT log at the bottom).

Currently running your Lineage OS 16.0 build for the SM-P900 which works like a charm (no Wi-FI issues).

Any prospects on Lineage OS 18 for SM-P900, or a fix for the current Wi-Fi issue in Lineage OS 17.1?

Kind regards,

Frederic

[Galaxy Note Pro 12.2 Android Development] hal_9000:
I'm using this ROM (latest version available on this post date) and it's working pretty fine, so thanks so much for this breath of fresh air for our venerable old tablet.

The only serious problem I found so far is in the multi window feature. The split screen mode works flawlessly but if I tap the free window (I don't know if that's the feature name on English) I momentarily get a floating window of the current app and then the system crash and restart.

I guess this won't be fixed, as the latest release is from a year and a half ago, but I think it's good to inform at least to know whether other people are having this issue too.

Regards.
[Galaxy Note Pro 12.2 Android Development] bankbandit:
That gives some confidence that may be I should finally mod mine.

Just a few questions... Is palm rejection working OK? Are other features of S-Pen, such as air command, working the same as in stock?

And what about DRM such as Widevine for the likes of Netflix HD etc?
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Never will on custom ROMs as Samsung doesn't publish the necessary details.

Just drawing, marking, writing works.

Read that additional app does it but idk name or source.
[Galaxy Note Pro 12.2 Android Development] bankbandit:
That's unfortunate.

But what about palm rejection and Windevine DRM? Or are these not working either?

I would just try it out to see for myself, but with Knox, I think it's a one-way street? I've shied away from messing around with the Note Pro for fear I may not be able to restore it to stock.
[Galaxy Note Pro 12.2 Android Development] hal_9000:
Hello.

For the part of the S-Pen, as bmwdroid said, it's almost impossible to have this in a custom ROM. As far as I know the only ROM newer than the latest stock ROM which have extra features for S-Pen working on SM-P900 is YAMR by bonuzzz, but it's just Marshmallow. As for the palm rejection, I didn't test it specifically, I can try later, but usually the system cuts the response on touch device when the pen is touching or hovering the screen. I will try to test it later.

Same for Widevine. Didn't check it. I will try later.
[Galaxy Note Pro 12.2 Android Development] hal_9000:
By the way, I'll take the opportunity to mention another two minor (or not so minor) problems I noticed.

First the left part of the status bar, where the notifications icons are shown, is ridiculously narrow. With only a few notifications it gets filled and a dot appears indicating there is more hidden notifications, which is incomprehensible as there are plenty of empty space between the notifications icons and the system icons on the right of the status bar.

The second one is that network usage monitor is not working. The data usage on wifi settings is grayed out and as a consequence (I guess) when I enable the traffic monitor on the status bar settings it shows constantly "0 kb/s". I tried third party apps to show the current traffic speed and they show always zero too.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Of course Knox will be triggered but that results ONLY in loosing guarentee.

At that devices age you will have none anyway, won't you?

Returning to stock is very easy using Samfirm_reborn to download latest mulitple part stock from Samsung servers and flashing it with Odin 3.0.9.

Done it many times with my different Samsung devices.

Btw. before flashing LOS your device has to be on Lollipop bootloader (as you didn't state it's condition).
[Galaxy Note Pro 12.2 Android Development] bankbandit:
Please let us know when you get a chance to test out. These are deal-breakers for me.
[Galaxy Note Pro 12.2 Android Development] bankbandit:
Thanks for the clarification on Knox and the procedure of recovering to stock.

My concern regarding Knox is less to do with warranty (due to its age, as you rightly pointed out) but how it would impact DRM features such as Widevine that I mentioned previously. As that's an unknown to me, and that this device still plays a minimal part in my professional workflow, I felt it best to leave it as it is until I can confirm all essentials work in custom roms, or I finally retire it.

My device is the SM-P900, running stock Android 5.0.2, kernel 3.4.39-5726670. I believe that's the last stock version in my region.
[Galaxy Note Pro 12.2 Android Development] hal_9000:
Well, I'm afraid I bring bad news. First only Widevine L3 is supported, so not luck with HD streaming. As for the S-Pen, there is no palm rejection at OS level but it rather depends on the application to ignore touch while using the pen. In addition the three tests I made of touching simultaneously with my finger and the pen ended all with a system hang, not a crash-and-restart, simply a hang leaving a fixed image on the screen and an unresponsive tablet until I pressed a few seconds the power button to force a restart.

Hmm... I'm thinking what to do now. It's true that these problems will not affect too much (if any) to my daily use, but in the other hand I don't feel completely comfortable with a system with these few little pitfalls (I hope there are no more) which may cause a hang or a crash if you aren't careful. I was happy to have a relatively new version of Android on my old device, but may be I go back to my old LineageOS 14 ROM, or even go back to Android 6 with YAMR, to preserve a near-to-stock touch and S-Pen features... Thinking, thinking....
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
That's what I'm still using.

Vanilla 20220208 it is.

17 I found not stable enough.
[Galaxy Note Pro 12.2 Android Development] Alyonas_boy:
I have recently discovered this device and am thinking about getting one second-hand. Loving the 12.2 inch screen size. Would anyone recommend this device? Or is there something better for its price bracket and size?
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Although owning a P900 I'd recommend a P905 as ROM development for it is better.
[Galaxy Note Pro 12.2 Android Development] erkan.alper:
Hello thanks for good work. Can you make this with sim version(sm-901)? Because The other ones have s pen issue

Has anyone tried to build the rom whit the latest lineageos fixes? I cant seem to get it to build anymore on my part. If nobody else can build the rom i guesse that this is the end for my P900 tab and i better go to a newer one
[Galaxy Note Pro 12.2 Android Development] rexyrex:
anyone got the wifi working on this ? i can get it to work via a hotspot but wont connect to home wifi
[Galaxy Note Pro 12.2 Android Development] Alyonas_boy:
Oddly enough the P905 only has a quad core CPU from snapdragon whilst the P900 and the P901 has an exynos octa-core. I bought my kids the 10.1 note pro 2014 that have the exynos and they are really snappy. I would hate to downgrade to a quadcore with the 12.2. this realization has come late though as I had many opportunities to get a P901 for dirt cheap whilst only searching for the P905, even though it has better ROM support.
[Galaxy Note Pro 12.2 Android Development] kipa:
Thanks author for this ROM. I have installed it successfully (P900). The only question is whether somebody knows how to make camera tablet working? May be solution could be to install another compilation. Does somebody know which one has working camera? Thanks all good man helping others who don't have time and knowledge how to overcome old android and no cooperating producer.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Afaik on 17 nobody was able to get camera working.

14.1 has working camera.

That's why I stay on 14.1.
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Hello it sounds like this is the rom for this tablet. I'm ctually on mine right now. It's rooted and it's been so long that I don't even know what rom I have or even how to find out. It's got TWRP v2. 8.7.1 and seems to work fine. It was dropped once and the screen got smashed pretty good but still worked fine. I found a mint one ebay that the wifi didn't work so I put my motherboard in it and boom like brand new until recently the battery scrapped out so the old one went in that had been replaced anyway. I play WGT golf and theres a forced update to the game now which won't work on Android 5.0.1. From what I've found 5.1 and up will work. Would this be the easiest rom to install or is there one you'd suggest?

Thanks and happy holidays,

TJ

I forgot to add it's the Note Pro 12.2 wifi version not the Tab
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
I've got the same but mine stays on 14.1 as I don't want to miss the camera and it seemed to me being more stable.

A good how-to you'll find here by @Retrial.

Just have to customise it to your P900.

Gotta make sure 1st that it's on latest stock as that bootloader is needed afaik to get custom ROMs working.
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Hi thanks for the info- I haven't quite been in the loop on Android rooting for quite a while... but sounds like you have. I think it's a good idea to go with what you got- the 14.1. So just go the the rom in the picture and follow the instructions from the link you gave me? I have an old two v2.8.7.0 I think- will that be ok? Anything you think I should know?- hey thanks again

TJ
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
the pic doesn't open so idk what you got

As I wrote gotta customise it accordingly

Would use a newer one.
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Hi thanks the rom I was referring to was

[ROM][7.1.x|SM-P900| Unofficial LineageOS 14.1 (v1awifi)​

It's The second one down in Android development. I think I saw other variations of it.

Anyway, in the link you sent, I see you can install bootloader and modem or separately. Wouldn't the bootloader come with the rom? And since it's a WiFi tablet there wouldn't be a modem?

Is this the download for the rom?-

Exynos5420 Device Builds

He mentioned to get recovery but the link is no good- do you know where I get it? I thought it would be in the rom.

So I need to get twrp- what version do you have- when reading up I see that people use specific versions for roms.

Thanks for the info- I've been outa this game a long time
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
The link refers originally to flashing SM-I9195 S4 so therefore it says something about modem as well.

Afaik the bootloader is included in the stock ROM that's why flashing latest stock prior to flashing TWRP and LOS is mandatory at least for P900.

It's not to be mixed with boot.img which is in the ROM

correct

this link is long time dead.

If you want to I could upload my latest downloads (stored on my NAS) for P900 from this server (see pic)

recovery is never! included in the custom ROM.

Go there to get it

Mine is either on 3.5.1 or 3.6.0 gotta check

I've learned that not all work the same as afaik the official ones are not always tested (read somewhere) prior to being published.

Welcome back in the game.
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Well last night since the links were dead for the 14.1, I found another rom in the list for the p900 that after clicking on it, all the downloads were blurred until you clicked on them. Anyway, I downloaded the twrp in there and the supposed rom, put the tablet in download mode and flashed the twrp and the tablet rebooted so I went to where I keep all the root apps clicked on recovery and now the tablets stuck in a 'Recovery is not seandroid enforcing'. I can only go back into download mode. I tried reflashing the recovery again thinking it may reboot tablet but no go so I do t know how to get out of this and undo it so I can get it back to the state it was in? Any suggestions

Thanks
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Thanks for the twrp downloads... I had to figure out how to get it recognizable in odin to flash it last night but I needed to flash the stock rom first as in before it was rooted? I totally didnt know that and have it all locked up
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Gotta link for me to check?

Imho something must have gone wrong during this procedure.

Which TWRP was it?

That's fine. Flash latest stock and start from scratch with official TWRP.
[Galaxy Note Pro 12.2 Android Development] bmwdroid:
Odin recognises .tar files as flashable.

Don't understand?

What do you mean with "locked up"?
[Galaxy Note Pro 12.2 Android Development] tjmethod:
Q

Well locked up to me since I can only get it to change to download mode and that's it after messing it up

Well since I did what I did, these are the only two screens I can get to...
[Galaxy Note Pro 12.2 Android Development] tjmethod:
In case you can't see the screenshots The first one is 'recovery is not the seandroid enforcing' and the second is download mode
