That's where I fall foul. Not sure which recovery I use and not got any experience with twrp.

I've had to flash the rom on this t810 before as I didn't realise was a Hong Kong model but that just used odin
[Galaxy Tab S2 Android Development] bmwdroid:
What does it look like?

1st or 2nd pic?

Don't understand fully what you mean about Odin?

That's anyway needed for flashing TWRP.
[Galaxy Tab S2 Android Development] diablosblade:
Odin was mentioned as thought this process would be similar. Instructions initially don't mention twrp.. havent used that.

It currently looks like 1st pic.

Does installing twrp change it to 2nd pic or give a new recovery screen option?
[Galaxy Tab S2 Android Development] lpedia:
@bmwdroid's second image is TWRP. You still have the stock recovery.

Odin can only flash ROMS that are stock Samsung - so to flash LineageOS you'll need a custom recovery, and TWRP is by far the best-known.

Odin can flash custom recoveries such as TWRP, however. Also, once you have TWRP, you can use TWRP to upgrade or downgrade itself - you only need Odin for the first TWRP install.

The official download site for TWRP for the T810 is https://dl.twrp.me/gts210wifi/. Start with the latest version, 3.5.2_9-0, and if that doesn't work properly for you, try earlier versions. For this flashing, will need the

.img.tar

file, not the .img. [To update TWRP with TWRP itself, you use the .img file.]

This site https://www.getdroidtips.com/flash-twrp-recovery-samsung-phone/ describes the full process, but note that the Galaxy Tab S2 devices don't have an option to unlock the bootloader. That step isn't needed, but you do need to enable Developer mode and turn on OEM Unlocking [if that option is present; if it isn't, it isn't needed] and USB debugging as described in the Unlock Bootloader section. Also note that you MUST turn off "Auto reboot" in Odin before you try to flash TWRP, and you MUST immediately reboot to recovery mode after flashing TWRP, using the buttons as described. The instructions make this sound optional, but it isn't. If you do not force the device to reboot to recovery once, immediately after flashing TWRP, the device will automatically overwrite the custom recovery with Samsung's stock one. After TWRP has been booted once, it'll stay put.

Hope that helps.
[Galaxy Tab S2 Android Development] diablosblade:
ok - didnt like the most recent TWRP - got stuck at downloading screen even though odin said pass

had to use down+home+power to reboot
[Galaxy Tab S2 Android Development] diablosblade:
do i keep going backwards on the version numbers until a TWRP works? just seems to stay on the downloading screen unless i down+home+power to get out of it
[Galaxy Tab S2 Android Development] diablosblade:
not sure how but i finally have image 2.

3.5.2_9-0 with the 8 grey buttons
[Galaxy Tab S2 Android Development] diablosblade:
got latest lineage and full gapps.... do i copy them as zips or extract them then copy? (ext sd card route)
[Galaxy Tab S2 Android Development] diablosblade:
everything installed. how long on first boot. has been a good 5mins on circle travelling across screen...

(full wipe - didnt have anything worth keeping)
[Galaxy Tab S2 Android Development] diablosblade:
4 forced reboots later - im in.
[Galaxy Tab S2 Android Development] lpedia:
Congratulations! ;) (y)

I remember having a bit of 'fun' like that when I first started trying to get TWRP on my T710.

BTW: to force a Samsung device to power down, plug it into a charger before holding Vol Down+Power. If it's on the charger, that will shut it down. If it isn't, it'll power down briefly and then reboot to system.
[Galaxy Tab S2 Android Development] djcasl:
Just a weird question, my Samsung Galaxy A3 has similar fingerprint button on it like the TabS2. Probably other phones as well. Is the fingerprint hardware / driver that much different? Or could you maybe use that one in this build? The driver i mean.
[Galaxy Tab S2 Android Development] diablosblade:
keeps randomly booting to recovery mode.... should i try an earlier lineage or is that indicative of something else?
[Galaxy Tab S2 Android Development] lpedia:
I see you found my post #1824 listing (what I know of) the problems, which unfortunately do include random rebooting to recovery. I've seen these bugs in all versions of this 17.1 build (and with different versions of TWRP). These problems weren't in the 16.0 build. [But no, I don't know where to get a copy of the 16.0 ROM.]

The Havoc ROM thread for this same series of devices has reports of the same kinds of issues. With both LOS and Havoc, the problems seem inconsistent and are not confined to particular device model/s. Any particular model might not show any bugs at all; or have bugs coming up so frequently that it's unusable; or the bugs could be just infrequent enough that it's workable.

So if your device's TWRP reboots are making it unusable, I suggest you try Havoc. Because the issues are so inconsistent, your device might be more usable with Havoc than with LOS. [ROM][UNOFFICIAL][10] Havoc-OS 3.x [T710][T715][T715Y][T810][T815][T815Y]

Anyone else have an issue with encryption? When trying to enable it I always get rebooted into an error screen that says "Encryption unsucessful"

I'd like to use the tablet encrypted so would be appreciated to know if its not just a me problem.

Thank you.
[Galaxy Tab S2 Android Development] metterschling:
I was trying to upgrade (with data/system/dalvik/cache wipe) my encrypted 715 from LOS 16.0 January build to 17.1 May build today. It failed with the same error others reported on the previous page. ROM reports corrupt data partition after successfully performing the wipes, installing the ROM to the system partition,, rebooting and entering decryption password (validated as correct). Pressing "wipe data" on that screen does nothing but a reboot to TWRP. Using the April build did not make any difference so there might be a general issue with encryption in the 17.1 builds unless I am missing that upgrading to 17.1 needs a full data format (which was not required for other devices I upgraded). I did not test the Format Data option in TWRP for a start from scratch as it will wipe the internal sdcard as well and I'm scared getting back that data correctly although I backed it up using ADB. So for now I reverted to (encrypted) LOS 16 using nandroid restore.
[Galaxy Tab S2 Android Development] zed011:
16 is more stable anyway. I keep getting the boot animation on 17.1 and wifi disconnect more often on my 710. I'm tired of that causing a battery drain and a dead tablet
[Galaxy Tab S2 Android Development] GoldSolitude:
do y'all have links to gts210wifi los16 builds? dunno where to find them. does anyone build them with new security patches? thanks.
[Galaxy Tab S2 Android Development] metterschling:
Since ripee removed the los16 builds from his Google Drive and stopped providing los16 builds nobody has stepped up to continue that version, unfortunately. If there is a slight chance to get los17.1 to the same maturity as los16 I totally understand the decision to focus on the newer version. As always, developers are rare and have a "real" life, so we need to be patient or look for a more frequent updated alternate device/ROM. I am very grateful for the work ripee and ananjaser have done, it has greatly extended the lifetime of our S2 tablets!
[Galaxy Tab S2 Android Development] Bacchuss:
Thank you for a wonderful ROM, @ripee! My yesterday-acquired T710 runs smooth as butter on LOS 17.1.

Some notes for others:

* Don't look too hard for the OEM Unlock in the Developer Options, it may not be there and then you can just ignore it.

* Have an SD card with the desired ROM and GApps and some space for your backup available: You may not have USB connection in TWRP and this way you don't need it.

* If you keep losing USB connection every few seconds, switch to a different USB port on your PC.

* If Google asks you to register you fingerprints for a second time during setup, just skip it: It did register the first set.

* Yeah, the shutter button of the default camera falls off the bottom: Use a third party camera, Proshot seems to work fine here.

A small question: I suppose I cannot count on the updater reminding me to update, right? I'll just have to manually (dirty?) flash the new security updates through TWRP every month?
[Galaxy Tab S2 Android Development] tofe62:
Hello,

I installed this ROM which works perfectly on my T710.

I just have a little problem with the fingerprint recognition. During the 1st ignition, I type the code then if I try to turn off and on again, the imprint works only once. After that, I always have to type the code. I specify that it does it with this ROM but also the other ROMs under Android 10. Stock ROM worked fine.

OP says to just download below... but nowhere in the original post does it show the link to TWRP

was it removed?
[Galaxy Tab S2 Android Development] bmwdroid:
Why don't you look here:

Download twrp-3.5.2_9-0-gts210wifi.img

Download page for twrp-3.5.2_9-0-gts210wifi.img

eu.dl.twrp.me

That's the latest official.
[Galaxy Tab S2 Android Development] lpedia:
As a general rule, TWRP images for just about every device are available from the official TWRP site https://twrp.me.

On that site, go to the Devices section, find the device you're after, click on its link, then on the device's download page select one of the links in the "Download links:" section. This brings up a page (eg, the one @bmwdroid has just pointed out) with links to all recent versions of TWRP for that device, in .tar and .img format.

Hi Ipedia, Ripee,

I just new join to flash my T710 from last month. I also can meet random infinite boot loop on LOS17.1 about 2~3 days a dead loop. Therefore, I try Havoc OS3.12 looks good on first 3 days. However, I found it dead again tonight. ha.. (battery 0%)

Not sure if there any new W/A for this (I also turn off my device to W/A) or any suggestion build for T710?

Looks LOS16 may be a good choice but no available link for download now.

Thanks Ripee for the build LOS17, I only have this dead loop issue on it. others are all awesome !! :)

[Galaxy Tab S2 Android Development] ripee:
@retiredtab has been quietly working on R for T810, which should be easy enough to port over to the other 3 variants. For this reason, I haven't been keeping up with Q builds as before, that and these wifi and booting problems that ananjaser1211 has pushed to our sources.

I posted an R build for T810 a few hours ago. According to retiredtab, it should be working as well as Q, but I haven't tested it yet myself. I will port the other 3 variants today and run builds for them as well. Only once R is as reliable as Q will I rebrand this thread.
[Galaxy Tab S2 Android Development] kabelgleichung:
Will you provide updated Q builds (including the discussed patches)?
[Galaxy Tab S2 Android Development] ripee:
If those updates are already in the sources, sure. But sometimes devs push new fixes only to the new version because it's sometimes a pain to keep track of multiple branches.

But once I sit down to work on gts2 today, I will run Q buids as well if the Q branch is ready.

Edit: I just checked the Q branch, and yes it does have both fixes added. New Q builds should be up in around 3 hours.
[Galaxy Tab S2 Android Development] yoshkapundrick:
Thank you so much for the new update.
[Galaxy Tab S2 Android Development] ripee:
I can add the TCP patch to the 5433 sources without any problems, as I've added it to my qcom Note 4 source already.

Also like I've been doing all summer for the qcom Note 4, I plan on revising 5433's sepolicy when R becomes stable and enforcing the kernel, then collecting more root logs to fix any selinux-related bugs.
[Galaxy Tab S2 Android Development] retiredtab:
If that's the case, you might want to remove the 18.1 Aug 24/25 builds until you can patch TCP/IP with either kernel or Derp-fest patches.

[Galaxy Tab S2 Android Development] LedgendaryEpics:
3 questions for dev

1: why do you have so many roms under you in regards to the samsung tablets? (not saying its a bad thing or anything just that its so many to keep up with)

2: are any of your builds selinux non permissive? (im planning on using this tablet as a media hub and dont want to give these crack apps elevated permissions at will)

3: do you delete your old builds or is there another way to find them?

@LedgendaryEpics, I suggest you tag the person of whom you're asking these questions. The XDA system will then alert them about the mention, and they're more likely to notice that than just a another post in one of their threads, especially if they have a lot of threads to cover.

Hello Guys,

Does anybody face an error 255 while installing latest avaialbe LineageOS 17.1 ROM on Samsung TAB S2 T710 ?

I tried several times to install in after full wipe from TWRP, format data, re-installing TWRP for different versions, nothing helped.

Only one rom which is I'm available to install without any issues is the 14.1 Lineage OS.

I'll appreciate assistance on this.

Thanks! :)

[Galaxy Tab S2 Android Development] benwatkins:
Am I imagining it or did a previous build have the option during install to chose between hardware or software navigation buttons? I've always hated the hardware buttons on the Tab S2 so it was great to be able to disable them and use the soft navigation bar.

While I'm here just want to day a big thankyou to the developers for everything they do on this. 6 years and still nobody made a tablet to improve on the GTS2 8. This ROM is the only thing keeping it alive.
[Galaxy Tab S2 Android Development] lpedia:
@benwatkins - in Android 11 you can normally get the on-screen navbar by turning on Settings > Gestures > System navigation 3-button navigation, but that option hasn't been turned on in this ROM.

@retiredtab posted elsewhere about how to activate the option in another of his ROMs. It should work for this one, too: https://xdaforums.com/t/unofficial-...galaxy-tab-e-sm-t560nu.4150709/#post-83375469

hey hey! i could use some help owo

have the t710, and really want to install this ROM, but anytime i try to flash a twrp vesion thats higher than 3.3.1, my tab goes into a bootloop (and, if i can't install a newer version, i just get the ERROR 7 thing).

has any of you encountered the same issue? if so, how can i fix it? thx in advance :D
[Galaxy Tab S2 Android Development] lpedia:
Hi, @apolowentrougue.

I've used several versions of TWRP and am now using 3.5.2_9-0 on my T710, all without any problems. I've not seen any boot loops with any TWRP version.

Can you describe what you've done so far?

Some things to note (apologies if you know all this, but you didn't give much detail):

Before installing LineageOS the first time, you must make sure the device has the latest stock ROM, so the bootloader is the one that the LOS images (and TWRP or other custom recovery) are expecting. If the bootloader isn't the correct version, things can go wrong. For example, boot loops could be due to a wrong bootloader.

You must have the correct TWRP for your device. The T710 is gts28wifi, and official TWRPs for the gts28wifi are on https://dl.twrp.me/gts28wifi/. Flashing the wrong TWRP could certainly result in boot loops.

Make sure you have the right ROM for this device. TWRP gives ERROR 7 if asked to flash a ROM that doesn't match the device.
[Galaxy Tab S2 Android Development] benwatkins:
Thanks for helping with my nav buttons query. I should have said I already managed to find the solution to turn it on through adb. I was just curious to know if I was dreaming about it being an option during install!

It means Samsung never releases 64-bit drivers for the 5433 kernel, so it functions as an arm32 device. It cannot run 64-bit apps.

That depends how much you know already. Don't bother learning from Youtube, too many builders have too many bad ideas about how best to work with the rom sources.

You can also use Heimdall if you have Linux. Odin is perfect on Windows, you don't need to click on anything you don't understand because its default settings will do what you want when you have no idea what you're doing lol.

I've installed the 18.1 build from 08/24 and it works pretty good for me. Today I saw the new build from 09/17 and directly downloadet it. Now I wanted to install it, did reebot to recovery and was surprised TWRP seems to be gone. I reached an other recovery (system standard?). I'm not sure how to get back TWRP now, because I don't have an PC anymore. Is there a way to install TWRP without an PC?
[Galaxy Tab S2 Android Development] ripee:
The rom is flashed to a different partition than TWRP. Force reboot by pressing volume down and power together. As soon as the screen shuts off, press the volume up, power, and home buttons together. You should see a blue line of text in the top left of the screen when the white SAMSUNG appears.
[Galaxy Tab S2 Android Development] lpedia:
@Ike13, is the 'other' recovery LineageOS Recovery? During LOS setup on first boot there's an option to install LOS Recovery. If you tick that box, it'll overwrite TWRP with LOS Recovery. Could you have done that accidentally when installing the 08/24 build?

LOS Recovery can of course do LOS clean installs and updates, so you don't really need TWRP if that's all you need to do.

Otherwise ... I don't know of a simple, safe way to install TWRP without using a PC, but someone else might.
