Hello everyone i am about to get tab s7+ and i love the table just one question we have root and twrp why there is no custom rom and if i am rooted how to update the software also what do i lose with root what magisk don't fix? Thanks in advance
Hi. I think the lack of custom ROMs is because the device is fairly new - hence - not that popular, additionaly being an Android tablet. I ditched my Iconia A500 years ago and never thought I would go for a tablet again until this gem came out. I would recommend you to try it first for some time and play with it because there are tons of features (literally) in this device that would doubtedly work on any custom ROM in the beginning. At least that's my personal opinion - stick with stock for some time. Samsung have done a really great job! ....And what's more - Android 11 with One UI 3.1 is rolling out these days. It will allow you as far as I've heard to use Google discover on your foremost left screen instead of Samsung daily.

A general thing to lose with root for all Samsung devices would be those Knox-related stuffs, namely Secure Folders.
I've been trying to boot a GSI on the tablet but up to now all attempts have failed. The tablet refused to boot, despite there were no problems with the flashing.
I personally don't really care about those Samsung features as I've very little use of them at the moment. I bought the tablet mainly for its size and its 120Hz display, but after using it for a while, it seems the tablet's stock firmware is indeed not good enough (especially with the Android 11 update) and unless there be plenty of hope for custom ROM/GSI, you'd better off getting a recent version of iPad Pro 12.9 inch for nearly the same price, if rooting is not important.

Sorry but could you possibly share what's not good about the firmware? I've never used such a feature rich device before and everything runs smooth as butter, I'm using it as screen extender for Win10 laptop, Chromecasting, Samsung Secure folder with encryption, deeply integrated with all Samsung apps, I connected my 2TB NTFS external HDD with Paragon's NTFS plugin that allows NTFS write operations, home Internet runs at impressive speeds (50 and more MB per sec download), I draw a lot and the only thing that I've changed is the launcher. Of course if custom ROMs support all of these features it would be perfect!!!

You're right about the other features. For office/productivity works this tablet is an excellent choice.
On the other hand, this tablet's performance is very disappointing when it comes to gaming. I'm currently dealing with some touch-related issues when playing games (none of which would be a fatal issue for office/productivity), and comparing to my old tablets, I was expecting much more performance according to its specifications.
I think the tablet was never meant for gaming at all to begin with, however the specifications.
I'm working on a lineageos 18.1 bringup but this is the first time I'm dooing this, so I don't expect it to work very well. I'm fairly new to android development but recently I got official maintainer for resurrection remix for the oneplus 6 and 6T.

The Z4 Tablet is possibly my dream tablet, it has a great screen, microSD slot, good battery life and it seems dev-friendly.
I've got no Sony experience and I see surprisingly little custom ROM development. How 'dev-friendly' is this tablet? Does Sony provide source codes, drivers? Are they easy in unlocking bootloaders and flashing stuff like radios? Does it seem likely custom post-Marshmallow ROMs will be cooked in 1,5-2 years from now on?
do some research!
e.g. here "Anybody work on root?" much off topic posts unfortunately
there are two section with the title "Development" here ...
look at the phones: Z3+ and Z5 (nearly the same sources)
and all you need with almost useful documentation in SONY's Developer world:

I admit my question was a bit lazy, but it'd be pretty easy for people like you with lots of experience/knowledge on this Sony platform to give me a general idea.
I ordered a Z4T, but while reading this subforom while waiting for the shipment, things start to itch me a bit.
I'll anwer my own questions the way I see it now: Sony is pretty developer-friendly by providing source code and build instructions, but it's pretty buggy and there are very few developers doing stuff for the Z4T. I guess it's because of the bad availability of the device and the relatively small user base. The people @ FXP build ROMs, but I haven't heard much about how useful these builds are. If anything, I heard people downgrading from the 5.1.1 build. Rooting is only possible by unlocking the bootloader and flashing @AndroPlus' custom kernel. His current TWRP build has a bug that makes it impossible to restore a device backup.
Sony provides the option for unlocking the bootloader, but you'll completely lose your warranty. Furthermore, the TA partition will be irreverably changed and you'll lose functionality.
Marhsmallow has been announced, so there's that.
SONY's devices are good compromise for me
@jelbo
Good summary!
My opinion:
The SONY devices are good hardware. I like them because they are water resistant since I lost a phone after cycling in heavy rain.
I have a Tablet xperia Z with CyanogenMod on it. Android 5.1
The start with that 3rd party ROM was slow and it was quite buggy. Also battery life was worse than with stock ROM.
I have a SAMSUNG Galxy S5 phone. They have Knox-protection on their devices. Quite evil compared to SONY. Because it was released with Kitkat I could root it via exploit and keep Knox untriggered. I could get CyanogenMod, even Marshmallow Alphas for the phone. But the drivers are not that good and the battery life with stock is very good (up to four days for me).
So I will keep that phone on stock and I used Titanium Backup to get rid of SAMSUNG's bloatware.
SAMSUNG do not provide documentation and many of their SOCs are proprietary - no chance to do any development for these devices.
Long post short: SONY is very open and relatively easy to hack on their devices.
Better (now) in price and features than the Nexus devices IMO. I would never buy a device without any chance to do development on it.
I think the bug in TWRP will get fixed soon (has bitten me once).
Thanks for your kind reply

Sounds familiar. In my experience with the last few phones I've had, AOSP-based ROMs were always a tad slower and less battery-friendly than stock or stock based ROMs. For example, the stock 'Google Play Edition' ROMs ran like a dream on my HTC One m7, but others were always less smooth / battery friendly.
So, for the Z4T I'm not partularly worried about the lack of 3rd party ROMs. I'll be fine with stock rooted. But for the longer term, because of the unpopularity, I think it's unlikely to see much going on in a year from now on and that kind of makes me doubt my purchase.

Yes, but not more evil than Sony I think. Samsung's bootloader unlock 'trips' Knox and it'll disable features like secure storage and services that depend on it. It's also irreversible. It's an awful lot like Sony's irreversible TA partition 'tripping'.
Because it was released with Kitkat I could root it via exploit and keep Knox untriggered. I could get CyanogenMod, even Marshmallow Alphas for the phone. But the drivers are not that good and the battery life with stock is very good (up to four days for me).

I could root my Galaxy S6 using an exploit, without tripping Knox. I'm running 5.1.1 with an engineering bootloader, while still having my Knox untriggered. It's a luxury I'm not gonna have on the Z4T, unless an exploit will be found.
SAMSUNG do not provide documentation and many of their SOCs are proprietary - no chance to do any development for these devices.

Yes, it's one of the reasons I want to avoid a Samsung as my new tablet. Exynos is a black box, so custom, stock-based ROMs will be the best you can get. BUT, I'm doubting now. Custom, stock-based ROMs are fine with me - as you mention, battery life is great. And on top of that, Samsung is so popular that lots of development is being done. I think chances are bigger to see the Marshmallow successor being ported for older Samsung devices than we'll see on this Sony Z4 Tablet in the future. But that's an assumption, I don't have Sony experience, but I see things re pretty dead here, even though the device was released quite a long time ago.

The microSD is an essential part for me. If the Pixel C would have had a microSD-slot I'd have chosen that. Development and future updates are a huge selling point for Nexus devices.

Let's hope so.
Hopefully the Z4T will get some more love soon, as I have just sent my Pixel C back and taken a punt at a open box Amazon warehouse deal last night with 40% off the LTE
I love my Z3CT, Z3C and Ultra, which have had great support from the devs, so am expecting the Z4 to be the best hardware of the lot, but would also love a root method while keeping the bootloader locked for now.
Heres to hoping perhaps MM will lead to some kernel exploits.

Dont get me started on the Pixel C from Google UK pricing error on day 1 and their refusal for a week to refund or swapout 32g for 64g devices, due to their error; then I had a hardware fault with the screen not responding after 24hrs of use. I found their support just awful More issues were being reported in the xda forum and I decided I wasn't going to spend £550 to beta test for google. Nice solid device but heavier that the Z4 and sliding the keybard across the keyboard to remove it, just made me nervous of scratching something everytime I did it.
To be honest the Z4 forums are very quiet, but so were the pixel c's; as a few people were commenting.
I had to root my Z3 Tab by loading the Z3 phone firmware and rooting that, as that had a kernel vunerability and the kernel on the Z3 tab didn't.
Once the Z3 phone firmware was loaded and rooted, I could backup my TA partition and reload the Z3 tab firmware, rooted.
Its generally the phones that get root and the tabs have to utilise what they can, unless of course a dev has the tab.
The tab forums got much busier once the device had a less risky root method.
Sad to see that Nut hasn't got a recovery done, but I am assuming that due to root only being available by unlocking and losing TA, so limited testers, but haven't had time to read the history yet.
I have to say though that the Z4 is fantastic in comparison to the Pixel C and I am very glad I have reverted to the device that I know especially at £360 for the LTE version + keyboard on Amazon open box. First time using and the device is pristine. To be fair the Z4 is many iterations of getting it right and the Pixel is googles first try. Once its at Pixel C v4 it will probably be very good!
Heres to hoping MM is officially released soon, so the chances of rooting may get better.
from Nut
This is the reason why I didn't release XZDR for the Z3+/Z4/TabZ4 yet, too much difference with the Shinano and older device trees.
Edit:
That should be solved with 2.9 though...

Seems the 64 bits is a material change, so things need to progress in 2.9 from my early readings.

Thanks for your reply, good info. I'm glad to hear some reassuring comments on the Z4T. Looks like you had a great deal as well. In the Netherlands they're hard to get. I payed €635 for the WiFi model... I'm still doubting a little bit to go for a discounted Samsung Galaxy Tab S 10.5 for €380 though. I read it'll even get Marshmallow in April. Price difference is pretty big and there's lots of stuff for it already.
I'll have a look in some Xperia phone subforums on XDA.

Yes there are no deals on the Z4 Tab in the UK and all the new prices are the same retail price.
Thats why I decided to take a chance on the Amazon one, as I could return it if it was damaged or anything; and normal 12 months warranty with Amazon.
For me I haven't had a Samsung since my Tab 7.7 and wouldn't personally have another, but each to their own. The devs were always complaining at Samsung not releasing all the source code to their SoC's, wheereas Sony seemed to be more dev friendly.
The Z3 Tab is fantastic if you didn't mind the 8inch, but I am hoping once the Z3+ root is forthcoming and general 64bit root/recovery is done, then we will have some progress; he says, not being able to help the devs on whats seems a lot of work.

It's a shame that such a good device is so low supported by free developers even though it seems it's more open by the Sony in comparison with Samsung.
I noticed that some people think in the thread that not so much users have this device. I have an old phone so called HTC desire HD which was released in the faraway 2010, it is excellent supported as it even has the contemporary android 6.0. I don't believe that there are more HTC decide HD users rather than xperia tablet z4 users. Moreover, I see as my comrade-users of our device crying ? everyday on a Russian 4pda.ru site, that we wait but there's no a good root method, there is no a good description or a video showing us how does the only custom ROM work. What works and what is broken. And just not seeing good news over the course of several months. Of course, I am very disappointed in dramatic fashion, but I hope The change will come.
Thank you for attention!)
cut the drama
- you should not compare a phone to a tablet (numberwise)
- look into the fora for phones Z3+/Z4 and Z5
they have nearly identical SoCs, differences a sometimes build options
- there is a HUGE xperia cross devices forum here with tons of additional info
- the Z4 Tablet became available in June 2015
- the first sources from SONY showed up in .... June 2015
- I rooted the device in July - having done no Android programming or rooting before
- I ordered the device after researching (see below) and before there was root available because my findings showed that there would be sources and documentation from SONY so that if all else fails I would get later a custom rom or could even roll my own
- a video for "seeing" developing/hacking? Dream on...
- there is lots of documentation (even video) available, maybe no video on how to do a web search or an xda search
- searching (and reading and trying things out) worked for me - coming from SAMSUNG phones with no prior development experience on Android ... TRY IT

Good summary.
Small point, but the rooting element is by unlocking the bootloader, which not all will want to do. It is though an option that exists and we are thankful for those that have done so in order to progress the dev support.
Hello dear people, I hope I can be forgiven for asking a potentially stupid question.
With my 850F batteries failing, I am hoping to get some more months out of this once expensive phone. So I've been looking at some custom ROMs to see if they make a difference. But it seems like the fingerprint reader never works. People tell me it's because the driver source isn't available.
So, is this a question of legality (the driver cannot legally be included with roms) or of possibility (the driver is deeply dug in)? Because if it's the former, I was wondering if there's some file I can take out of the stock firmware and put onto my phone to make the fingerprint reader work with any rom?
Also, I would like to express my dissatisfaction with the terrible support Samsung has given for this phone. We got one late update from Kit Kat to Lollipop. It looks so vanilla it makes one wonder why it took so long. The black background colors from Kit Kat changed to white, a terrible choice for an OLED screen. So with regard to the already meager battery, this update has been a regression.
I'm trying to get as many months out of this phone as I can until the next generation of phones comes out. I love the Samsung hardware but I might look for brands that are either more frequent with updates or open source enough so that custom firmware development is not hindered by unsupported hardware.
I'm thinking the next phone should just be under 5 inch and powerful enough to be a desktop computer running full Linux, like Ubuntu OTA 11 (if someone introduces Android compatibility) or Maru OS, so I don't have to carry around a laptop anymore.
Fingerprint scanner works fine with all Samsung based ROMs (OzcanROM and EpsilROM) only CM ROMs (CM and ResurrectionRemix) don't support it (aswell as heart rate monitor)

I hadn't even thought of the heartrate monitor yet!
Yes, I tried those non-Samsung ROMs. I thought if I use the Samsung-based ROMs, I might as well use the Samsung ROM.
Because they use proprietary drivers, and samsung does not disponibilize them, well, when marshmallow launch, its is POSSIBLE that Samsung bundle the source code with a generic fingerprint driver, as fingerprints reader support is a generic and system wide thing in MM, just like when hardware acceleration via GPU was an propietary thing in android 2.3 and being default on android 4.0
I'd like to get to as close to vanilla as possible. Not a fan of Samsung's ui or bloat. I'm coming from the tab s1 which had some pretty good roms. There are none for this device and it's almost 6 months old. I would make one myself but lack the necessary skills
Most of the newer top end Samsung Tablets get very little developer support since they cost so much. Happens with every new tablet having people asking where the developer support is for it. Samsung newer UI much nicer and any vanilla roms would take away most of the functionality that makes the tablets great. Apparently the S5e has some dev support.
Problem is Samsung seems to be super slow with there updates for the S7.
I've owned the S7+ SM-T970 for like just a week and I'm already feeling impatient waiting still running off the Oct. update while I keep hearing about about UI 3.0 update hitting there flagship phones.
Do you think at some point down the road when or before OEM support ends we can look forward to some working roms or Treble GSI options ?

Not everyone gets the update at the same time (don't know how they handle when and who should receive the update). I only got a November update a few days ago (though some claimed to have already gotten it) and it offered few improvements. The tablet still feels the same as usual.
As one must choose between custom ROMs and Knox (especially warranty), I'm currently at a loss myself, and for the time being I haven't heard of anyone trying (or succeeded in) booting a GSI on S7/S7+ probably because of this, although it's theoretically possible (again thanks to Treble). At least we now have TWRP... it might be better if one day custom kernels become available.
So far this is the only tablet I know that can offer 120Hz display. My current phone (Razer Phone 2 which is also 120Hz-capable) still doesn't have a specialized ROM but I can already run GSIs on it with adequate performance. For new devices, going for GSI might be easier, but performance-wise it still has a way to go compared to specialized ROMs.
Think it has to do with the fact that snapdragon is locked on samsung
Years ago I rooted a phone I had to the latest Android, only to find that the hardware wasn't up to running a more complicated OS, even the Cyanogen version that was equivalent to the original Android version didn't exactly breath much life into the old dog.
Given how shockingly poor the experience on my T820 can be on the stock ROM, I find myself once again tempted to give a custom one a go, but was wondering if the newer ROMs place significant additional load on the hardware? Is it worth the effort? Does it make them responsive?
I don't use the tablet for anything heavy-duty; mainly what I want is responsive browsing, Skype and some basic apps...

@imacleod,
Based on the views and comments I see for custom ROMs for your tablet, this ROM:
[ROM] SM-T820 TWEAKED....................[rom] sm-t820 tweaked
SM-T820 TWEAKED 5.1 ***** PIE ***** 20JUN2020 T820_CTD5_TWEAKED_5.1_DB4_by_rorymc928.zip Based on latest stock CTD5 firmware Tweaked, stable, zip aligned. SU/D Forced encryption disabled Deknoxed Debloated (GPU driver updated to latest...
forum.xda-developers.com
appears to be the best choice for improving your tablet's performance. If you are serious about installing it, check out the most recent posts in the thread. You will find a very useful post that goes into great details about how to install the ROM properly.
I feel you regarding sluggish performance on a stock Samsung tablet. I had a Samsung tablet a long time ago and it felt like watching paint dry when I tried to simply play a video. Also, what is it with the HUGE bezel size on Samsung tablets ? I recently bought a Lenovo Tablet and it has a very thin bezel.
In any event, good luck with your tablet !!
Thanks. I was hoping for some feedback from people that had applied a ROM to the S3, whether they found it transformational - or perhaps not - and whether the best idea is to go for the latest and greatest, or stick at the lowest level that's got general support.
I'm not one who's installed a custom firmware, but I see you've not got much response. This device was very expensive at launch, so was a hard reach for many people. Fewer people means fewer developers.
The custom firmware available for this device is quite sparse. In addition, there seems to be troubles getting all of the hardware to work correctly. They're not placing any load on the device as its the same kernel version as stock.
That being said, I do believe the S3 is past its support period, so will not be getting new firmware from Samsung.
Reading the fora for the custom firmware show that the device can be more responsive than stock (as long as you don't need the hardware that isn't working).
Additionally, rooting and debloating the stock firmware has shown increased performance for those who have done it (including myself). I'd recommend this route prior to attempting a custom firmware unless your primary goal is to ditch samsung and google.

I'm not one who's installed a custom firmware, but I see you've not got much response. This device was very expensive at launch, so was a hard reach for many people. Fewer people means fewer developers.
The custom firmware available for this device is quite sparse. In addition, there seems to be troubles getting all of the hardware to work correctly. They're not placing any load on the device as its the same kernel version as stock.
That being said, I do believe the S3 is past its support period, so will not be getting new firmware from Samsung.
Reading the fora for the custom firmware show that the device can be more responsive than stock (as long as you don't need the hardware that isn't working).

Thanks for the reply. I did actually take the plunge through the week and installed rorymc928's rom. So far, I'd say that it's more usable than stock - e.g. it's not so slow that entering a PIN after a restart hits the screen lockout out before I'm done - but not overly stunning when browsing (perhaps my expectations are too high). It has made me a lot less inclined to reach for a hammer/put it on eBay, and it may be the best balance between what's available and losing functions/features. If I feel brave I may try a more advanced tinker at some later point in time...
If you want to get an idea what Samsung thought was important for this tablet, watch some HDR content from youtube. Gorgeous!
But... Not really useful. Android tablets are a teeny niche, but someone should be able to produce something for the market!
Is there anything that predicts developers will take more interest in the Galaxy S23 range, so we can finally have a custom ROM scene for Galaxy?
Maybe because the S23 (all devices: S23, S23 Ultra, S23 Plus) ditch Exynos in favour of a Qualcomm SM8550-AC, an S23-exclusive version of the Snapdragon 8 Gen 2
Did we need a change of wind to make things turn out differently for this device versus earlier Galaxy S ranges? I really hope it's time for renewal, as if im not wrong, the last one that had a nice ROM scene & development going on was the Galaxy S5+ which is so many years ago..
I am talking about a sizable custom ROM scene (all recent devices were dealt a bad hand, or completely lacked it) and the least that would make me very happy: the entry of LineageOS, something that's not been there for years, surely for reasons.
Due to having been away from Galaxy as a result of the lack of ROM scenes in prior devices, I am out of the loop regarding Samsung Galaxy platforms for development support, can anyone state what the main things holding it back have been in recent years? Things being locked down too much, like with other major brands? For what the main blockers are, is there reason to believe that the S23, or the move from Exynos to Qualcomm chips on the other hand, will make a difference? Because as far i know, Qualcomm is the proficient & preferred platform for most devs.
Well as much as Samsung makes everything depend on Knox not being tripped, I doubt it.
I noticed that something may be ongoing when it comes to custom ROM (LineageOS, chipset) work for Galaxy S23+, see: https://forum.xda-developers.com/t/lineageos-progress.4582781/
Development there can benefit S23 Ultra vice versa, as it's similar and also sm8550-ac, who knows if that person succeeds they'll move on to S23 Ultra afterwards. I know it's speculation, but in my book these are hopeful signs.
Rom scene has been dull on this side due to Samsung Crippling devices when rooted (Knox being permanently tripped - hence killing resale value) and Dev's losing interest in Samung. We have 2 roms and 2 devs actively supporting the development here which is nothing like the Galaxy S5 or Note 4 Days.
Aside to the above, The stock devices are so good, that there's nothing more you can achieve by rooting which can outweigh the cons of rooting.

There exist at least 2 other very good and stable Roms with lots of mods for the Ultra.
ATN Rom and VN Rom.
just noticed this thread about gsis on the s23 range : https://forum.xda-developers.com/t/how-to-gsi-on-s23-ultra.4564249/#post-88279455 (seems to be interesting)
(also noticed a discussion on installing other gsis on the xiaomi 13 : https://forum.xda-developers.com/t/xiaomi-13-gsi.4572035 )
seems to be interesting to me ... maybe I ll buy an S23 to try (I saw a used one that was not too expensive) but maybe I am not avanced enough to succeed

Nice, i was mainly interested in LineageOS/for development to get going on something like the latest Snapdragon 8 Gen 2 (sm8550) chipsets, if only we can get a flagship from today in the best possible software package which is where i won't settle for anything less than LineageOS. Not in any case, no matter how good the stock ROM is - it's about freedom, control, privacy & security - where in LOS everything is opensource and auditable (as opposed to OEM.. you don't know what may be running and how secure it is). Not to speak of even faster security patch levels than from any vendor. I also believe you won't feel the true power of your high end hardware until you're running an OS that's practically as clean as AOSP, such as LOS. It's like people dont know any better, and that raw performance (flagships..) offsets your perception anyways.
Since this topic, i've set my gaze on a new device with the same chipset (sm8550) as the Galaxy S23 range - the Motorola Edge 40 Pro, a flagship.. even if chaptsand (as per https://forum.xda-developers.com/t/lineageos-progress.4582781/) can pull it off for Galaxy, i found a way to kickstart the effort for Moto Edge 40 Pro as well, by sponsoring it and bringing a few devs together. If you're interested in that effort, read some comments before and after this one: https://forum.xda-developers.com/t/...-motorola-edge-30-dubai.4536169/post-88509185, and it still has to be moved into its own topic. But if that gets accomplished and for Galaxy it doesn't turn out well, at least ill have something to recommend to anyone that wants LineageOS on a latest tech flagship. For those that think like me, and won't ever settle for less.

thanks ! very interesting and generous from you !!
but I must say I am more interested in a hardware with a "flater" screen than the Edge 40 Pro.
an inconvenience with the S23 is that you are losing OTA with stock rom if you root it ( https://www.xda-developers.com/how-to-unlock-bootloader-root-magisk-samsung-galaxy-s23/ )
so, unless there is some AOSP rom with updates for the S23, it seems safer to me to go for the Xiaomi 13 (after I had a look at this guide : https://forum.xda-developers.com/t/...bootloader-root-flash-twrp-flash-rom.4538433/ ) ... or maybe I ll go for the Poco F5 pro 12/256 as it should start with an early bird price of 499E tomorrow, although it s an SD 8+ gen 1 instead of an SD 8 gen 2 (oh it will be 479E with the 20E coupon on https://ams.event.mi.com/fr/poco-f5-series-product-launch ) ...
good luck !
