Hi there,

I am tempted to install LineageOS 17.1 on my SM-P600, but I am stuck at step one, I cannot unlock the bootloader.

I have experience of installing LineageOS on Google Nexus 4 and 7. However I cannot unlock the bootloader on this Samsung tablet. I tried looking for information everywhere, but nothing really works.

I can see the tablet using adb devices command when it is on and connected to my PC. When I use power & vol+ combination I cannot see the device with adb command. Therefore I cannot run fastboot flashing unlock or fastboot oem unlock commands.

I tried installing TWRP using ODIN3 and the device boots back to normal when it restarts.

Could someone please lead me to the correct procedure? What am I missing here?

Thank you in advance.

Hello,

Does anyone has the previous crdroid build (v 6.23) for t705? The latest doesn't boot for me.. thanks!

[Galaxy Tab S Android Development] korayesque:
Unfortunately it didn't work. I can get to the point where I can put heimdall print-pit command on my Win10 PC, it starts working but gives an error on downloading device's PIT file. As follows:

Some people suggested to use ODIN3 for this error, but I cannot get TWRP to work when I install it with ODIN3? By the way, I cannot unlock the bootloader and the device is not rooted as I mentioned earlier.

Any help would be appreciated...

Some thing on my mind:

- Remove all unneccesary USB devices

- Try another cable? Looks like tranfer problems to me.

I have SM-T800(Tab S) and want to try this version

I'm on Android 5.

Can I flash Lineage without flashing latest Samsung firmware?
[Galaxy Tab S Android Development] pinsb:
Could someone who has installed the latest LOS 17.1 and is willing to act as a guinea pig please try to now install the original RIL from the last official Samsung firmware and then report back if data now works?

Please, don't try this if you're even a little unsure what you're doing as I'm not taking the blame if your Tab catches fire and burns down your house as a result. I can't try this myself as my Tab S is currently configured for some specific stuff that is a PITA to reinstall due to two factor auth being required, so if we get reports it's now working OK I'll then bite the bullet and put aside a weekend for the upgrade.

Hi M8. Thank you for your reply. I used T700XXU1CTK1_T700NEE1CTK1_NEE with ODIN, prior to TWRP recovery.

It needs those patches to work properly:

But I can't upload to there gerrit. So someone needs to compile it. I won't just yet for you

Seems like the right firmware. You started the firmware before flashing TWRP? Then flashed the right TWRP for your tablet? If so, I dunno. Maybe try another T700 android 6 firmware?
[Galaxy Tab S Android Development] golagha11:
Yes, installed the firmware, booted up. Turned the tablet OFF. Then flashed TWRP, wiped data, tried to install both from SD-card and internal storage, also downloaded the file lineage-17.1-20211118-UNOFFICIAL-klimtwifi.zip twice, same results. Md5 check is good. I need Android 8 or greater on this device.
[Galaxy Tab S Android Development] Hazou:
Just to be sure, what TWRP package did u use?

"Warning: No file_contexts. E3004: This package is for device : klimtwifi;"

First warning looks like TWRP issue. Second one, looks like using wrong zip file or even TWRP
[Galaxy Tab S Android Development] golagha11:
Thanks again for taking time replying to me. I used "twrp_3.0.2-1_sm-t700.tar". TWRP worked with "VanirAOSP for SM-T700, but since that is based on Android 6, I deleted it.
[Galaxy Tab S Android Development] Hazou:
Your twrp image is out of date. It doesn't work with newer Android versions. Use

https://eu.dl.twrp.me/klimtwifi/ and the latest version: 3.5.2_9
[Galaxy Tab S Android Development] golagha11:
WOW. You are just the king. Thanks a lot, that did the trick. Successfully installed the OS, but got a error message for the GApps, probably have the wrong version in there as well. Downloading for ARM64 as we speak. You really saved my day. I spent 2-3 hours yesterday and couple of hours today. Once again, thanks a lot. wish you the best.
[Galaxy Tab S Android Development] Hazou:
Good the device works. U need gapps for Android 10. Don't use arm64. The device has a 32 bit processor.
[Galaxy Tab S Android Development] golagha11:
Thanks M8. I thought that the platform was wrong since i got an error when I tried to install "open_gapps-arm-10.0-stock-20211125.zip", but I downloaded open_gapps-arm-10.0-full-20211125 and that did the magic. Thanks again M8.

It would be fantastic. The developer for this is @8224Freak
[Galaxy Tab S Android Development] Hazou:
If he wants, I already uploaded the patches to my git. They should work, as they do on mine. But I haven't looked at any bugs it could make.
[Galaxy Tab S Android Development] MegaMike99:
Hi guys,

i installed TWRP and "lineage-17.1-20211118-UNOFFICIAL-klimtwifi" and

installation works very well.

I also set an 128GB-SD-Card to expand the internal memory.

So the ystem says:

"4,09GB of 16GB used"

"2,13GB of 128GB used"

So, sound good, but whenever i try to install an APP i always get the

error message "Not enough memory".

Any idea why???

Mike
[Galaxy Tab S Android Development] glennza:
Will you be making this available as a flashable zip? I'd love to try it on my T805
[Galaxy Tab S Android Development] Bawdy George:
Make sure Master Limiter and Playback gain control are on. It's possible to set the level of those and accidentally leave the toggles off. Then play some audio and check if the driver status is Processing: Yes. I have also forgotten to disable the stock AudioFX driver in the ROM, which will block Viper if enabled.

If all those conditions are met, I don't know what to tell you, It has worked on every device I've tried.

great, thats working. thanks

Anyone know how to build a device tree?
[Galaxy Tab S Android Development] korayesque:
OK, I was able to install lineageos 17 on a Samsung SM-P600 using the method described in the following video:

I basically used odin v3.14.1 to install an auto-root tool file, which I got from here (and followed their directions):

Root Samsung Galaxy Note 10.1 2014 WiFi P600 with CF Auto Root Tool

Root Samsung Galaxy Note 10.1 2014 WiFi P600 with CF Auto Root Tool. Click through for downloads and step-by-step guide.

nerdschalk.com

Then I installed twrp (twrp-3.5.0_9-0-lt03wifiue.img.tar) using odin v3.14.1 but with Auto Reboot unchecked in Options tab (as described in the video above).

Then I started the tablet in recovery mode and voila twrp was working. Then I backed up existing system and files. I mounted the drive and copied:

lineage-17.1-20211118-UNOFFICIAL-n1awifi.zip

open_gapps-arm-10.0-pico-20211105.zip

to TWRP folder.

Then I installed lineageos first and open_gapps second. I wiped as suggested in the video above.

It rebooted and works perfectly!

Thanks for this wonderful build, thanks all the help efforts, and thanks to the owner of the video above. All works great now. A new lease of life to a very capable tablet.

Can you please make a T700/705 version?
[Galaxy Tab S Android Development] glennza:
Installed okay but now I am getting quite a few random reboots. It seems to be connected to the existing issue with video/webview. Pages with embedded video previously caused the tablet to freeze up, now it reboots!

The only other ongoing issue is that after rebooting it won't let me login with PIN for quite a while. Annoying but I can live with it.
[Galaxy Tab S Android Development] Hazou:
I don't have the issue with webview tester from the playstore. Do u have some apps in which webview crashes? Not that I can fix them, but i do like to have a look.
[Galaxy Tab S Android Development] glennza:
Mainly in Google News but I've seen it in some other apps on occasion. It seems more stable on older versions of webview, I'm currently running v54.0.2840.
[Galaxy Tab S Android Development] sebek147:
Hello. I just got this tablet - sm-t800. Is this rom better and faster than stock? Ive had some issues and lags in some games on stock - for example fruit ninja - Is the performance better on this rom? And is is stable enough?
[Galaxy Tab S Android Development] CessnaBroon:
Not sure on T800, but without Gapps, it runs like a dream on T700. With Gapps, acceptable, a bit laggy, but great performance in games. Better than stock.
[Galaxy Tab S Android Development] sebek147:
Thank you for your answer. I saw a few gapps packages, i do care about gapps, but not all of them. Just YT, Gmail, Maps. Maybe I can install a small package of them and not lose a performance.

By saying without gapps you mean you dont have ANY of them?
[Galaxy Tab S Android Development] CessnaBroon:
I've tried with and without. In general use (with) of stock, I saw laggy notification slide at times, and random app crashes, especially camera, but very good game performance. Without, no issues, except you can't do anything without gapps lol
[Galaxy Tab S Android Development] CessnaBroon:
Hi!

Does anyone know how to use the exynos5420 device tree to build a ROM? I'm trying to learn how to build ROMs, and this is a crucial part I need to know.

Many thanks,

Cessna.
[Galaxy Tab S Android Development] sebek147:
Thanks again for ur reply. The final question - is lineageos 17.1 better than 14.1? I dont know which rom should I choose.
[Galaxy Tab S Android Development] CessnaBroon:
The 14.1 has Android processes that repeatedly crash, and then forces a random reboot. You're better off on the 17.1. Hope This helps, and good luck!!
[Galaxy Tab S Android Development] WLQ:
@Hazou do you have a hint on how one would apply those patches?
[Galaxy Tab S Android Development] AluMinioume:
Hi, I use T800 on LOS14.1 and I don't have this problem. The tablet is slow just after start, but 3 minutes later, it runs smoothly.

I first installed LOS17.1, the very first version. It was working fine, but the RAM management issue made me go to LOS14.1. I wonder if there has been any progress and if since that time LOS17.1 has gotten really better?
[Galaxy Tab S Android Development] CessnaBroon:
Again, I can't really comment on T800 (I'm T700), but @ISoreo 's custom kernel speeds things up a lot, and the hardware management is much improved.
[Galaxy Tab S Android Development] CessnaBroon:
By the way, can someone please give me an update on the random crashes situation? Is it still a thing, and if yes, how do I fix it, with links to any files necessary? Many thanks :)
[Galaxy Tab S Android Development] ISoreo:
random crashes from gpu, i have no clue to fix it yet just add some config from old branch to make the 5420 more stable
[Galaxy Tab S Android Development] CessnaBroon:
Great, thanks! I tried to develop but couldn't get it working lol. Does that mean the Webview issue is no longer a thing?
[Galaxy Tab S Android Development] ISoreo:
Of course no bro.
[Galaxy Tab S Android Development] t800Friend:
I’m new here and this is my first custom rom project. I’m totally impressed about the great work from so many enthusiasts. Sadly, it looks like I need your support to come forward with my first custom rom project ;-(

My device: Samsung Galaxy Tab S 10.5 WiFI (chagallwifi) SM-800 with Firmware CSC-Code: DBT.

I followed the instruction I found here, installed successful TWRP via Odin. Afterwards I installed lineage-17.1-20211118-UNOFFICIAL-chagallwifi.zip as well as open_gapps-arm-10.0-mini-20211204.zip.

After reboot I watched the green lineage loader semicircle. Unfortunately, it rebooted back to TWRP instead to forward me to the logon screen.

I found the hint “Changes from the deathly kernel added” (Only for the chagallwifi t800)

As next I started from beginning with “Swipe to factory reset“, installing the lineage zip, open_gapps zip and in addition the mentioned boot.img, with was included in the boot-t800-deathly.zip.

Unfortunately, that had not helped. My tablet always reboots into TWRP without booting into the logon screen. And it also not possible to shutdown the tablet because it reboots than again and again.

Wondering it someone has further advices for me?

Many thanky in advance!
[Galaxy Tab S Android Development] Hazou:
HI and welcome.

First, don't use the "Changes from the deathly kernel added". That was just a test for people who wanted to try it. But it doesn't work right without the rest of the changes to the system.

Make sure you had a Marshmallow version of the stock rom installed before even trying this. Then make sure you have the latest TWRP installed and try flashing just the lineage package. I did have some problems with different open gapps packages. So try it first without. Iff it works, maybe try another open gapps package.
[Galaxy Tab S Android Development] runekock:
@t800Friend

As @Hazou hinted, there are indeed reboot problems with recent OpenGapps.

Look at the recent posts in the OpenGapps thread:

https://xdaforums.com/t/gapps-daily-open-gapps-for-android-all-android-versions-devices.3098071

Unfortunately, that is often the case, because it is built automatically and published without any kind of testing. Hopefully that will improve in the future.
[Galaxy Tab S Android Development] t800Friend:
Thanks for your replies and support! It works now.

As @Hazou mentioned, I double checked first all and installed the lineage image only. Result: Lineage OS did not start. Steps which leaded to success:

TWRP -> Wipe -> Advanced Wipe: System, Data, Cache, Dalvik and Internal

TWRP -> Wipe: Factory Reset

External SD-Card: Delete all data from old Android 6 (Marshmallow) I guess I had to do that already right from beginning. Sorry.

TWRP -> Install: lineage image

Result: Lineage OS started!

I performed the same again, added the installation of Open-Gapps-Mini in addition before reboot (by the bigger versions, like FULL, the installation stopped because of too less memory space free). Saddly, an installation together with the GApps-Mini and GAapps-Micro was also not successful. But GApps-Pico worked, as @runekock had already guessed.

The configuration afterwards of lineage OS went smooth!
[Galaxy Tab S Android Development] pecigatt:
Hello everybody. I'm having problems with battery life on my T705, could a custom kernel help me? thanks
[Galaxy Tab S Android Development] runekock:
Probably not. In most cases, the kernel has only minor importance - the exception being if it is really badly optimized for the use case.

If you've never replaced your battery, then that's a lot more likely to be problem. Batteries usually last 3-6 years depending on how you use them.
[Galaxy Tab S Android Development] pecigatt:
the battery was recently replaced by an "original" one I found on Aliexpress. I saw some of 7800mah but I don't know if they are reliable.
[Galaxy Tab S Android Development] CessnaBroon:
Original batteries were 4900mAh
[Galaxy Tab S Android Development] runekock:
Try app AccuBattery to estimate how good your battery actually is.

Unfortunately, Chinese sellers are not always truthful about the batteries that they sell - but still, the more expensive offerings are often better than the cheap ones.
[Galaxy Tab S Android Development] pecigatt:
I haven't found on YouTube or forums if anyone has ever been brave to try one of these and give feedback if it's worth the purchase

[Galaxy Tab S Android Development] JohnieJ:
Hi everyone. I am interested in this ROM, but I am hesitant to try as I don't want to fix something that isn't broke.

This is what I have:

2 Samsung T-800's and 2 T-805's. All are rooted with Magjisk and Phil's root.

They run the IronMan V 3.2 Android 6.01 ROM's with IronStock V 3.2 Kernel.

I have a T800ZCU1CPK7 boot loader that was installed during the installation of the IronMan ROM. All tablets are identical with these items listed.

My first question is if I have a nano backup of all the stuff including the bootloader, can I revert back with TWRP if something goes amiss?

My second question is with the above firmware listed, can someone be kind enough to give me a step by step to upgrading to this ROM.

And last question, will I lose some functionality over my existing ROM?

Any help would be GREATLY appreciated.

P.S. I have read some of this thread, but not all. I hope I am not requesting something that has already been addressed. Just give me a link to the page and I can follow from there.

Thanks a buch for any help along these lines.

[Galaxy Tab S Android Development] CessnaBroon:
Question 1: Yes, you can do a full backup of everything from TWRP and restore successfully. I have done so several times in the past. As for Question 2, I would suggest using Odin and download mode to reflash the most recent stock firmware, and then follow the instructions in post 1. You could attempt a dirty flash, but I wouldn't suggest it in your use case. Use https://GitHub.com/zacharee/samloaderkotlin to download a tool which will retrieve the firmware for you at a reasonable speed.

Hope this helps,

Cessna
[Galaxy Tab S Android Development] JohnieJ:
It certainly does. Thank you very much. Fortunately I have both the t800 & t805 factory 6.0 roms already. I learned never screw with an Android device without having stock items available.

I will give this more thought before leaping into a pile of #$%#. Like I said, don't fix it if it isn't broke.:oops:

I am still open to any further advice if I can avoid the stock rom install first.

Thanks again

I have a T700 and am on the latest crdroid ROM crDroidAndroid-10.0-20211117-klimtwifi-v6.24-LuisROM.zip.

I had sometimes up to 30 seconds freezes.

The problem could be fixed by installing a ramdisk.

What I did:

1. install free swapper for root or alternatively swapper - root from playstore.

2. start swapper and create a 500 mb ramdisk. Enable swap on android startup.

Priority 60%.

Since then I had no more freezes. Tablet is absolutely smooth. So far no negative consequences.

PROBLEM: Not able to get wifi to work on klimtwifi!

I was on LOS 14.1 for years, the tablet was mostly used by my son. Recently, wifi would no longer work - it would always be off. Turning it on it would try for a few seconds, then return to off-state.

Then - happy to find this! No problems installing LOS 17.1 at all, but no wifi. Returning to stock, wifi would work. Installing LOS 14.1 (Vanilla), no wifi. Did multiple rounds of this over the weekend, until I decided to try LOS 14.1 (Deathly). On this ROM, the wifi acts normal and let's me connect.

I flicked through ALL 44 pages of this thread! Some others also reported wifi problems, but got no answers...

I would love to try LOS 17.1 (don't care about mic) properly, but can't do without wifi. Does anyone have any idea how to solve this? Does this ROM have the Vanilla-kernel, and my Tab for some reason needs something that is different in the Deathly-kernel?
[Galaxy Tab S Android Development] runekock:
@tigerfelix

Sometimes wifi problems can be about channels that have restrictions in some countries. If the rom doesn't get the restrictions right.

At 2.4 GHz, the channels 1-11 always work; at 5 GHz the situation is https://en.m.wikipedia.org/wiki/List_of_WLAN_channels complex:

List of WLAN channels - Wikipedia

en.m.wikipedia.org

Check which channel your access point uses, and if possible, change it to one of those allowed in all countries.
