Reinstalled the Samsung USB drivers and upgraded to latest ROM (19th Aug), but still no joy :(
[Galaxy Note Pro 12.2 Android Development] HuDeeb:
My bad, i had it too... Ok now try disconnect from computer, go to developers settings, enable MTP and restart tablet (just to be safe).

Replug to pc, and select on teblete​ dialog to use mtp (def. is charge) ENJOY

Hope that works
[Galaxy Note Pro 12.2 Android Development] Yemble:
Good straw, however, it is not getting to the point where the notification appears for the port mode selection. No USB notification appears on Windows either, so it is as if the tablet port is dead... and yet it still charges!

Please confirm which version of this ROM you are running.

now the source code for android o has been released when will lineage 15 for P900 be release?
[Galaxy Note Pro 12.2 Android Development] brock28:
i had the same issue it was the usb controller IC built onto the charging ribbon assembly after replacing the entire charging ribbon with a new on from ebay (10$ from china). It is an easy procedure if you have the basic ability/desire to open your tablet and change the ribbon (no solder req) . Also The battery on this unit is known to have a poorly designed connector with a poorly clamped connection inside the plastic connector harness many have had charging problems as a result such as not charging or taking so long to charge that it cant be used while charging as it would drain faster than it charges. IT is a reasonable assumption that a defective battery harness could cause enough current instabilities that it could damage the pc connectivity usb chip aswell. Good news is the battery harness is easily repaired by soldering the connections or reclamping them more securly or simply get a new battery and it would come with a new harness no work needed.
[Galaxy Note Pro 12.2 Android Development] Yemble:
I was already coming to this conclusion ;)

I have had previous experience replacing a USB ribbon cable on a Note 10.1 and have also replaced the battery on my NotePro 12.2, so I am happy to do this, if required.

All I am waiting for is someone to confirm a working USB port, for data transfer, on either of the most recent two ROMs.
[Galaxy Note Pro 12.2 Android Development] HuDeeb:
true to that... no popup dialog but there was an item in the pulldown notification list... my build is August​ 20th (my 1st one YEY!) took me a while to move over to the side of the FORCE, and the force is strong!

thank you "oh wise ones" your pah is strong and the force is with you!

BTW. do we need to wipe between nightly updates (at 14.1) other than cache/art and what should be accompanying the ROM at install? i didn't find any conclusive advice in searching the forum, on my other LineageOS (14.1) devices i simply wipe cache/art twice (before and after install) if i update manually. Thanks again for far out ROM :svetius::angel::svetius:
[Galaxy Note Pro 12.2 Android Development] Yemble:
I've decided to play safe and order a replacement USB ribbon cable (£7 in the UK). Decided not to wait, just in case the charging circuitry suddenly gives up as well !

No requirement to wipe anything between ROM updates, but it is a good idea to wipe Dalvik/ART prior to rebooting.

Is there a way to turn off WiFi power saving or power management?

ping the device or use ssh and you see the connection is all over the place. This is a side effect of power management.

On a Linux laptop you can simply do sudo iwconfig wlan0 power off. But there is no iwonfig in LineageOS.

I just want to use my tablet as a second screen and as a ssh-server. I don't care about battery savings, I have it connected to power all the time.
[Galaxy Note Pro 12.2 Android Development] Yemble:
On my Android 7.0 phone, within the WiFi settings, cog-wheel menu, there is a setting to "Keep WiFi on during sleep" which I have configured to "Always". You may also need to disable Doze which may override this setting? You might also wish to set the "Sleep" setting to its maximum value (30 mins) within the "Display" settings. Unfortunately you cannont turn the sleep feature off altogether. Or, better still, enable the "Stay awake" option in the "Developer Options".
[Galaxy Note Pro 12.2 Android Development] brock28:
Its my understanding that download mode is managed by a lower level bootloader and not the linux kernel/drivers that would be running the custom rom. If you can connect to a pc in download mode for a sustainable duration than I would conclude the problem is not hardware related.
[Galaxy Note Pro 12.2 Android Development] Redsandro:
Thank you for your kind reply.

I have this setting (or in my case "never sleep while connected to power"), but I think this is not the same. Sleep would make the wifi adapter unresponsive entirely. This power management however makes the wifi adapter only listen in certain frames, with an interval of roughly between 0.1 and 5 seconds.

This causes external communication (e.g. ssh) to randomly lag during typing.
[Galaxy Note Pro 12.2 Android Development] Yemble:
Great suggestion... I had not thought of trying that :good:

I'll give it a go before replacing the port cable, if necessary (it arrived in the post today).

☆☆☆ EDIT ☆☆☆

Bingo, that fixed it :D

First I ran Keis3 on the PC. As I last used this with a Galaxy-S5 years ago, it was out of date and prompted for an update, which I did. Then I booted the tablet into Download mode and plugged in the tablet USB cable into the PC. I immediately got the USB "bong of success". Keis3 did not recognise the NotePro, but it did know that there was something there.

Next, I unplugged the USB and booted back into Lineage. This time when I reconnected the USB, I recieved the bong of success again, together with the port mode notification.

Either the Keis3 upgrade, or the connection to Keis3 in Download mode, appears to have corrected this odd issue.

Now I have a brand new spare internal ribbon cable :laugh:
[Galaxy Note Pro 12.2 Android Development] dow4hurst:
How is Heimdall installation of LineageOS 14.1 possible?

Edit #2 Yemble replied with the answers. I could use TWRP to finish up the install. In fact, I used the Advanced option of a terminal to umount the SD card, transfer the LineageOS ROM and GApps zip files to it, reinserted and remounted using the TWRP terminal, and installed. Very convenient when you forget to put the zips in an accessible location! So, the tablet has the low latency option built into the newer kernel that wasn't present in Android 5.x. I plan to use the tablet as a music studio so required the low latency option. So, for those Mac OS/X and Linux users out there, heimdall-flash is a real solution over using Odin.

Edit #1 found that sudo heimdall flash --RECOVERY ./v1awifi-recovery.img --no-reboot works to install the custom twrp provided by the developer in the first post of this thread. My mistake was to use the Home+VolDown+Power instead of Home+VolUp+Power to go directly to the twrp recovery boot. So, it was wiping the custom recovery everytime. Once I followed the directions, I was able to get into the custom recovery. Making a nandroid backup now. Will post updates as I continue.

Initial question: What is the procedure to use heimdall-flash and heimdall-flash-frontend on linux to install the LineageOS 14.1 ROM, Gapps? The SM-P900 I have is currently rooted by a friend who had Odin. But, I'd prefer to learn how to use heimdall-flash to get twrp and the lineageOS rom installed, if possible. Would anyone be able to provide the steps? I don't see in the unzipped LineageOS files the ones that heimdall instructions typically talk about. I appreciate the time and help!

Thanks,

Dow
[Galaxy Note Pro 12.2 Android Development] Yemble:
Once you have TWRP installed, everything else can be done from there, rather than via the PC.

TWRP 3.1.1 is available for the P900, so that should be near the top of your list to upgrade. GAPPS should be flashed immediately after LineageOS, in the same TWRP session. Note that the P900 requires the 32bit ARM version, NOT 64bit.

Use TWRP to flash the full LineageOS ZIP downloaded from page 1, then GAPPS. If you want root, download and install the LineageOS SU add-on. You can then enable it once the OS is up and running.

Remember that the first time you flash a custom ROM, you MUST wipe most of the partitions (system, data, dalvik and cache) via the TWRP Wipe Advanced menu, prior to flashing the ROM. All apps will need to be reinstalled.

It is usually a good idea to wipe Dalvik/ART prior to rebooting the OS. TWRP gives you the opportunity to do this after each flash.

I have an issue when i play games, the shutdown screen pops up and the tablet auto shuts down. I tried with with a few games, first test was asphalt nitro
[Galaxy Note Pro 12.2 Android Development] Yemble:
Sound like it could be due to CPU overheating. I don't really think that the NotePro was ever designed with gaming in mind.

Having said that, my NotePro occassionally self reboots when browsing XDA in Firefox. I put this down to the ridiculous number of ads that need blocking on XDA.

---------- Post added at 01:12 PM ---------- Previous post was at 01:07 PM ----------

@thompatry

I know that it really early days, but is LOS 15 ever likely to be on the roadmap for the P900?
[Galaxy Note Pro 12.2 Android Development] eazy2001x:
So what can we do to resolve this? Underclock it? Not that i need to play games.. But it's annoying.
[Galaxy Note Pro 12.2 Android Development] HuDeeb:
how about ofloading the graphics to the GPU via developers options in "settings" would that isolate the CPU cycles. Or maybe limiting the CPU to 1300 MHz which will keep all avail. proccessors (all 8 of them, 4@1900 max. 4@1300 max.) equal?... Just dreaming :confused::angel::fingers-crossed:
[Galaxy Note Pro 12.2 Android Development] eazy2001x:
So i enabled developers mode and ebabled "force GPU rendering" and it worked.. Playing a few games did t do the random shutdown.. But question.. By turning this on.. What's the drawback?
[Galaxy Note Pro 12.2 Android Development] HuDeeb:
Sorry, i have no idea, i used to use it on an old tablet i had that had similar problems (Acer a500) so i thought to mention it...
[Galaxy Note Pro 12.2 Android Development] thompatry:
Yep that is to plan. We are working on it now. I don't have an eta yet.

Excellent, thanks for the confirmation :good:
[Galaxy Note Pro 12.2 Android Development] zamantas29:
hello and thanks for the great work. The only issue I identified is that the tablet doesn't charge when it's on. I have to turn it off to charge it. Any ideas?
[Galaxy Note Pro 12.2 Android Development] Yemble:
Are you using the correct charger (at least 2 amp) with a USB-3 cable?

The P900 display is a power hog, so the device requires plenty of PSU capacity if it is to charge concurrently. Even with the correct adapter and cable, the re-charge rate is dramatically reduced when the display is on.

I just leave mine on charge overnight.
[Galaxy Note Pro 12.2 Android Development] WelshnThirsty:
You could alter the kernel settings with Deathly Adiutor

In the Power and battery section, change the current in both AC/Mains input current (screen on) and AC/Mains charge current (screen on) to 2000mA.

I find this charges the tablet with the screen on without it getting too hot.
[Galaxy Note Pro 12.2 Android Development] Yemble:
Good call :good:

It's surprising how conservative the default charging setting are.

While the sms functionality through the phone doesn't work, hangouts is still working elsewhere as the sms client for Google Voice. I use it all the time on my phone and I'd like to use it on my tablet. The tablet doesn't even have access to allo or Messages through the Play Store. I can reply to Google voice sms messages through Hangouts notifications on my tablet, but I can't send them from the app as either the app crashes or my tablet does.

Anyone else getting occasional hard freezes or black screen reboots with the app Lecture Notes and this rom ? Granted am using a build from last month but I've consistently gotten hard freezes or reboots even after swapping out my battery and going way back to previous builds. I'm suspecting that maybe there is a memory issue with either Lecture Notes, this rom or both? Any help or insight on this matter would be greatly appreciated. Also what is a good settings to flush out or curb excessive memory usage with Deathly Adiutor?

P.S. Going to update to latest nightly to see if that solves my issue but I won't hold my breath. :P

I've never had problems using Lecture Notes and this ROM (I use it for work). I did use to get something similar when using other Pen apps (drawing programs--granted, I may have had the problem during this period with Lecture Notes, etc.), but I don't think I've had that issue for a while, and I keep up with the ROM updates. Hope you figure it out.

No

But there are decent remote desktop apps (the Microsoft one is alright)

I use a vpn (both for work and home) and remote connect to my work/home machine.

While it requires a connection, it allows to run anything and 'keep' everything, as you only use existing machines...

[Galaxy Note Pro 12.2 Android Development] Yemble:
Did you wipe the cache prior to rebooting after the flash?

This is what I do after every dirty flash and I don't recall ever having an issue, at least not recently. I'm running the very latest version of this ROM and everything seems OK.
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
I'm also now finding, as of the last couple of updates, that I'm having problems charging it unless it's completely switched off, ie not booted up at all, and just displaying the battery charging animation.

otherwise it's taking a long time to charge, and I'm leaving it overnight to find that it's not fully charged and won't finish charging until it's switched off.

once it's switched off, it charges fully as quickly as ever.

edit: seems my girlfriend is now having the same problem, on her galaxy tab pro 10.1, with the official build of lineage os. was saying it was going to take two days to charge, until she switched it off, now it's charging at a decent rate.

Turn off Screen-On Current Limiter

[Galaxy Note Pro 12.2 Android Development] phirestalker:
Does this mean the update system will work now?
[Galaxy Note Pro 12.2 Android Development] thompatry:
Hey Everyone,

Long time since I put a big post out. Couple big annoucement and a few minor items.

Two things that are big:

LineageOS is now officially supporting the v1awifi. I have worked my butt for this. So enjoy! You can find the downloads here or the OP.

Now what does this mean? The ROM will be officially signed and it should pass safetynet. (I might be wrong on this). Also all the builds will be "super" stable from LineageOS. The only downfall is that it will not have the latest and greatest features from our Team since we update the LineageOS repos about once or twice a month. So if you use it, but you would like a new feature be integrated but don't ask when we will merge a feature over to there. If you really want feature, switch back to the Exynos5420 Jenkins builds. I am going to always recommend to use our builds from download.exynos5420.com because it will always be up to date with the latest device changes and fixes.

Next.... There is finally a changelog for the v1awifi device. It is on the LineageOS website. You can get to it here or through the OP. I will say, this will not include all the latest and greatest changes from our Team. It is only mainly the base OS or the changes we move over.

Couple of minor notes. I am working on O but have no ETA. It is still very unstable and practically unusable. Please kindly don't ask for an ETA. I promise, I will get you a build as soon as I feel comfortable with it. One other non related item, our team is working on putting together our own ROM. It is called Echoing Moon OS (EMOS). It is purely based off of AOSP. So far the initial feedback is great. We still have a lot work to go but it is looking good. I will create a new thread when we get a stable build.

That is all! Thanks for being the greatest team to work with. You guys give great feedback.
[Galaxy Note Pro 12.2 Android Development] Yemble:
That is fantastic news :highfive:
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
that worked for mine, would you recommend i use deathly to sort out what seems to be the same charging problem on my girlfriend's tab pro 10.1? i believe that's a fairly similar device to the note pro 12.2, under the hood?
[Galaxy Note Pro 12.2 Android Development] phirestalker:
Just to clarify, the official build will eventually get each new feature from the nightlies here? The only difference is the speed at which the official build is updated right?
[Galaxy Note Pro 12.2 Android Development] thompatry:
Yes as long as she is run our ROM with our kernel.

Yes. Just at a much slower rate.
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
she's running the official build of lineage os, I've not done anything to the kernel apart from install lineage
[Galaxy Note Pro 12.2 Android Development] DaveUK:
Great news about going official!

Did you ever manage to fix the MHL problems?

Thanks again for your work
[Galaxy Note Pro 12.2 Android Development] thompatry:
It should work then since lineage is running our kernel.
[Galaxy Note Pro 12.2 Android Development] thompatry:
Yes I am still working on MHL.
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
is the screen on current limiter likely to remain on by default in future builds? is it only causing charging issues on a minority of devices?

excellent news on your rom going official, by the way. good work.
[Galaxy Note Pro 12.2 Android Development] thompatry:
What it is set at is default from Samsung. If you flash dirty, it will not override it. I am not going to make a change in the rom due it is technically not recommended and it could possibly cause damage. Highly unlikely though since the charging controller is very smart.
[Galaxy Note Pro 12.2 Android Development] Mr Creosote:
ah ok. so what's changed that it's only started happening as of the last couple of lineage builds?
[Galaxy Note Pro 12.2 Android Development] DaveUK:
Trying the new official build but getting the "setup wizard has stopped" message. All wipes done. Using the latest opengapps.

[Galaxy Note Pro 12.2 Android Development] DaveUK:
I did a workaround..... im up and running.

Check permissions on the Setup app

Wiped Everthing in TWRP Advanced (except my microSD card where the zips are)

Flashed the Nightly build

immediately flassh GApps

Rebooted....no luck

Tried above with a couple different GApps versions ( Stock, full, nano).
[Galaxy Note Pro 12.2 Android Development] Yemble:
I suggest you don't use the official builds yet as there is obviously an issue with their installation. Just grab the latest nightly from the link on the first page and install it with TWRP 3.1.1. I know this ROM works because I've been running it since the weekend.

If this is your first time installing this ROM, then you MUST update your Boot Loader first! There is a link on the first page (or at least there was).
[Galaxy Note Pro 12.2 Android Development] DaveUK:
Once you get the official installed I've had no problems. There is a workaround for the install problem but if your not confident about replacing files in TWRP then I'd wait until the installer is fixed.

I'll try and install this week's build when it comes out and see if the issue is fixed. Will post my findings.
