wifi Roms for SM-T807P

Hello XDA!
I recently purchased a SM-T807P (10.5" LTE/Snapdragon) with the intent to use it as a wifi device.
Will anyone tell me which roms work with this device? I've heard the challenge is to find a snapdragon rom?
Its rooted with TWRP on it already. Just need some tasty roms to play with.
If there is ANY way to get cyanogenmod on it that would be my first choice (I would even be willing to offer a bounty!)
I am already running the only one I could find specifically for SM-T807P.
[ROM][TW][SM-T807P Snapdragon] SuperSkilled Basic ROM V1 + Firmware
http://forum.xda-developers.com/galaxy-tab-s/development/rom-superskilled-basic-rom-v1-t3055473
I'm glad to find a custom rom, but am really for a lollipop de-bloated rom.
But ANYTHING that people have tried so far would be great.
OR anything that I should try that wont permanently brick my new tablet!
Thanks all!

Now you have twrp just make a full backup before you go messing and you'll never have to worry about bricking your tablet.
As for roms, pretty much all roms are based on stock, so just modify yours as you see fit.
Debloat, add mods, etc.

Considering that I am using a snapdragon version of this tablet maybe you could point me in the right direction about which roms work for that processor versus the other?
I know one of the issues was finding a rom that had the right kernel for my tablet.

No the kernel isn't the issue. Its that the t807p is partitioned differently than what the available ROMs are compatible with. I have the same tablet and as awesome as it it, there is very little support for it. No developers have it and its very difficult to work with without owning one.
There is twrp available which I assume you have used and rooted. There is a stock ROM on XDA that is lollipop that works awesomely. I just debloated it myself and tuned it with kernel tuner with stock rooted options. Xposed won't work without a deodexed rom either which is not available. But regular root options and a different launcher (I use nova) and i have it running pretty damn smooth.

I flashed the only KK ROM I found and got FC's to no avail. I then basically wiped the whole thing then odin'd to lollipop. I am stock now and you're right, it's a damn nice device. -- I wouldn't mind de-bloating it myself, do you by any chance have the 'safe list' to reference as far as which apps are good to go. Last thing I wanna do is get rid of some odd-ball system file that creates hell for myself.
Thank you

Just make a backup first with twrp before you go messing then use system app remover to debloat or just freeze with titanium backup . If you get an issue after removing something you can easily restore it.

No problem. First off, listen to everything xda senior member ashyx says. I have been dealing with my rooted t807p for a while and I have found all his posts on the tab s not just accurate, but extremely useful.
here is a post regarding safe apps to uninstall: http://forum.xda-developers.com/galaxy-tab-s/help/list-bloated-apps-to-uninstall-sm-t700-t2861180
Now what I have personally taken off my tab s has been the superficial apps. The magazine apps, office apps that I have no use for, While a lot of apps on the post may be safe to delete, it doesnt mean you should if you plan on using your tablet for wireless transfers, casting and what not. I prefer not to touch many of the "behind the scenes" apps. And also it depends on why you are debloating. Are you looking for more storage space? or for better ram and performance? Unfortunately, at least for my use, you wont save much storage space by deleting apps. But freezing them and playing with it makes a big difference. On just a standard recent apps clearing and maybe a push of my "fast reboot" app, and I can get my RAM to run at around 900mb and little battery drainage.
I hope this helps. Let me know if you have any other questions, I have played with my t807p for quite a while with rooting and have learned pretty well what works and what doesnt. I am no developer like the senior members on here but there aren't many people with our specific tab s.

I realize it's been a year or more, but do you have a link to the Lollipop ROM for T807P? I've tried the "SuperSkilled" ROM but it was KitKat. I looked for a Cyanogen build for this tablet but no luck. Looking for any ROM that's close to AOSP or at least debloated and is Lollipop or MM.

Simple ROM based on stock?

Is there a simple ROM based on stock (not ASOP) that removes bloatware from /system and makes more room? Something like Cataclysm, CleanCore, CleanROM from other devices?
Even better if it gets updates with each monthly security update and provides a simple upgrade path, rooted, etc.
Thanks!

CleanROM on extended hiatus.
The best I found was the CleanROM series from scolser, but he's had to but it down for a while, perhaps forever, due to family and personal health. I've really appreciated all he's done, given my share of donations and wish him all the best. (but I'll miss the great work he's done on the ROM)
Hope you all have a Merry Christmas.

Yeah, bummer. I hope he recovers and comes back.
Meanwhile I guess I can just remove some apps from /system to free up some space.

How about this one? http://forum.xda-developers.com/nexus-7-2013/development/rom-bad-boyz-nexus-7-stock-rooted-t3219148 There is a script you can run that'll clean up some of /system.

Help a novice please - have ROOTED Samsung Galaxy Tab Pro 8.4 (SM-T320) - Update?

I just received a used Samsung Galaxy Tab Pro 8.4 (SM-T320) - and discovered (not known to me before purchase) it is Rooted.
When I went to do an Update via standard Settings>about Device - it refused returning tablet modified.
also it had the App SuperSU (free) installed) which asked about permission on a couple of Apps I used.
I have absolutely no experience of Rooted tablets,
and currently have no idea how the tablet was rooted, and what with.
So I am seeking your patience and some advice about this, please.
Is there a way to return to the Stock installation?
If so, how to I check that this is possible?
Or should I keep the Root?
If so, how do I update the tablet?
eg: how do I check what, or if any, custom ROM has been installed?
or
which custom ROM do people advise I install?
Thanks for any advice.
Vincent

Just back up your valuable data and storage contents and flash stock via Odin. And I believe at this time point the updates are not of much importance, so if you're on KitKat you might as well ignore that if you can't spare time for backups.

Thanks for the reply.
Funny that was starting to be my take too.
Either leave it rooted as is - since it really is just KitKat 4.4.2 - but with more ability.
Or later when the spirit moves perhaps upgrade via a custom rom.
Thank you.

@vincent. I have the same tablet as you and I prefer to run the latest OS which is Marshmallow. As you state you are already rooted so you might as well try out a custom ROM. I recommend Resurrection Remix ROM by Vasumit and the XDA thread can be found here. Latest update to ROM is here. You will also need to install gapps. I recommend Banks Dynamic Gapps 6.X.X found here. Give it a try, I'm sure you will like it. ROM is buttery smooth and Vasumit updates it often. :good::good:

Thank you so much for your encouragement and suggestion.
Even though I have used Android on tablets and phones for years -
I am still a n00b when it comes to Root and Custom ROMs
I have heard of the more famous ROMs like CyanogenMod etc -
what makes Resurrection Remix ROM by Vasumit better than CyanogenMod
in terms of features and/or support please?
How easy (or not) are custom ROMs to undo?
Many thanks,

Personal opinion below: most AOSP-based ROMs have equal or slightly better support than CM because the team behind them is much smaller, but they might die out one day because of the same reason. CM maintains a huge number of devices and is the basis of many, so it's not likely to disappear soon. Also, CM is usually among the quickest to get to a new Android version while others usually sync from CM and start from there.
As of features, others are guaranteed to have more than CM. CM doesn't like adding features these days.

Do: Flash TWRP, make a full backup of your stock ROM, full wipe and flash the new one.
Undo: Full wipe and restore the old backup, or if you decide you don't want your data, use Odin.

Thank you very much for the very helpful reply -
this was about as good as I was hoping for -
really appreciate all the help I am getting here, thank you.
It will take a bit of time for me to get my head around the information - as it is all new to me -
and I want to proceed with care/caution so I don't end up bricking my tablet.
Gratefully and thanks,

Hey!
you could look at it this way, most of the people here have a hard time just ulocking the device and rooting it, not that yours is already done, might as well right. along with the proper research, your device could be one hundred times better, the stock OS of the tablet isn't that good (lets face it.) and with the current technology, it will have a hard time keeping up because the OS for this device is not that efficient (personal opinion). Anyways, it's still up to you to do it or not. Cyanogenmod has released the nightly version of Marshmallow 6.0 for this device. maybe you could check it out!! ^_^

Yes, thanks for the encouragement.
Seems ironic that I had done lots of look-sees (not quite research, but close) about rooting devices - and I actually now have one
(it was just unexpected on this Samsung Galaxy Tab Pro 8.4 (SM-T320)).
As you see I've decided to keep it rooted and am actively looking at which ROM to flash -
currently I am leaning toward the more conservative approach of doing the CM (CyanogenMod)
and rather than deciding between the snapshot CM-12.1 or the nightly CM-13.0....
perhaps I should just wait for a snapshot CM-13.0
(" and we’ll have a quality approved SNAPSHOT for CM13 sometime Jan." of course it is now Feb - so maybe soon?)
Thanks,

Don't wait for snapshots - they are just forked from nightlies at a certain timepoint and aren't more stable than nightlies. Just backup and flash a nightly, and if anything you feel unstable, restore the backup and/or wait for that to get resolved. I personally don't see anything disturbing aside from wonky external SD support (which is a universal bug across all 6.0+ ROMs).
P.S. The "Thanks" button is there - use it

The issue is mainly with how to use SD card as external storage (as on older Android versions), not with the new "adoptable storage" feature. That we don't have a definitive solution yet.

Problems with Lineage OS

Hi, I'm not sure if it's the right section where to post such a thread but I didn't found a better one for my problem.
I flashed lineage-14.1-20170213-nightly-find7s-signed.zip on my rooted Find 7 (2k version so Find 7s) with TWRP following all the standard steps (full wipe, ROM and gapps install, wipe cache/dalvik and than reboot).
Than when the ROM flash was finished (it took not as much as I thought) I rebooted and my screen become white with a grey OPPO logo in the middle and purple "powered by android" at the bottom (the usual power up screen but with inverted colors) and when I touch the screen it makes quick flashes with flashing black horizontal lines and it keeps being stuck in that way for minutes (way too much and it keeps doing that also after many reboots). The only way to recover the phone is to flash again Color OS (Android 5.0).
So i was wondering what's the problem with that ROM? How can i upgrade my old Android 5.0 to a newer 6.x or 7.x? Is there any rock solid ROM compatible with my F7s that I can flas with no such problems ?
Thankyou all for help!

OmniROM 6 is a mature and solid daily driver with the option to try OmniROM 7 which is still being improved regularly. Arguably the best ROM for Find 7.

It also has LVM support which allows you to merge your partitions so you will have more than 3gb of space for apps.
I've been running it for months, there are a few things that I miss from previous roms but is very stable and since this phone is getting old the ROM choices are getting slim. It's also the only one I can find that still supports LVM.

Thankyou both for helping me I found a list of omnirom ROMs in this thread https://forum.xda-developers.com/find-7/orig-development/omni-testbuilds-7a-7s-t3237065 , can i choose one of the last 6.0.1 to be sure it will work or can I trust the 7.1.1 updates?

You can trust both! And im not a hyper flashholic....

Just another few questions, LVM means that i can unify partitions in order to have more than 3 GB on device memory, right? I found that thread https://forum.xda-developers.com/showpost.php?p=55187001&postcount=558 is it better to use the .iso or the .zip to apply LVM? And when do I have to apply the LVM setup, before or after flashing the new ROM/Gapps?
Thanks again

Regular TWRP vs Codeworkx

My 5T will be arriving today (coming from the Moto X Pure Edition...just under 2 years old. Yucky!) and I'm reading about rooting. ADB/oem unlocking/fastboot/etc. are familiar territory for me. I just wanted to make sure of something quick: I saw the guide saying to get Codeworkx TWRP, but I also see TWRP has a dumpling recovery image. I'm kind of thinking regular TWRP is fine, but I'm always careful when unlocking bootloader/custom recovery/rooting. I figured I'd ask just to be sure.

The official TWRP has always had issues with encryption on this device. Basically it's been behind the curve on updates. Last I heard it's gotten better, but it's generally still recommended to use Codeworkx or Blu's version. Personally I'm using Codeworkx.
[RECOVERY][dumpling] TWRP 3.2.3 by codeworkx

Blu seems to be more updated at the moment and has Amoled, and Treble support for 5.1.5.
Not sure if codeworkx has amoled and treble...

DOWNLOAD KERNEL ZIP and RECOVERY
https://forum.xda-developers.com/devdb/project/?id=21949#downloads
twrp-3.2.3-x_blu_spark_v9.85_treble-op5_op5t.img works really nice for me on 5.1.5

Thanks for the replies! :highfive: I went with blu's version and have had no problems. I think I read somewhere (I can't find it agian, obviously...) that for a nandroid backup all screen lock safety has to be removed or encryption will prevent a restore. Would this be accurate? There's a lot of new stuff I'm trying to get used to with my 5T, coming from a closer to stock Android MXPE, especially the world of encryption. I wanted to try out some custom ROMs and wanted to make sure if I didn't like it I could restore to OOS easy. Apologies if there's a guide somewhere on the 5T forums...I've had this for 2 days now. Love it.
Another question about custom ROMs; are they as snappy as OOS? Every other Android phone I've had sacrificed speed for customization with custom ROMs. I miss the closer to stock Android look, but it's no deal breaker. I also really miss the option to make the volume buttons only control media. I tried Gravitybox for Oreo (Magisk + Systemless Xposed), but it wouldn't work.

@Moppusan with experience anything is just as snappy as anything else...
I deblot OOS and run microG on it, then if you know your way around Kernels, you can stick in EX Kernel Manager, or Kernel Adiutor and tweak up the stock kernel and get it smoother, or faster, overclock, get real crazy... RenderZenith seems like a nice kernel for OOS, it's a newer kernel version with newer features that seem to perform over stock.
It seems like, if OnePlus gave us a newer kernel version then we could have some nice newer kernel features in a stock kernel. OOS 5.1.5 is on 4.4.78 So maybe the next release of OOS will see a nicer more up to date version... Maybe some one running the latest beta can tell us what version it's on?
I'm getting ready to put up a guide, hopefully in a few weeks about doing the debloating and microG on OOS.
Remember OOS is a Custom Rom, from OnePlus...

@DoR3M3, well...yeah that is another way to look at it. OOS being a custom ROM.
I'm probably in the intermediate level of Kernel knowledge. I bought the pro/premium/donate/whatever-he-calls-it version of Kernel Adiutor and have read plenty of guides on cpu/gpu governors, hot plugs, over/underclocking, input boost, voltage, storage...governors?, net congestion and blah blah blah. I think the only thing that's really over my head is the tunables for the cpu governors. I've just found settings other people have tested and try it myself.

It would be great seeing such a guide ! Was thinking about a journey into the mirco land but my laziness holds me back :/

OOS is a Custom ROM, the only difference is that OnePlus is a manufacture, and because of Google's licensing, has to include the Gapps. But, I wonder if OnePlus can put up OOS for download on their site, that is GappsFree, now that would be nice!
If you're not running Linux and you are into Android, I highly recommend it. Of course there are things specific to Android, but it comes from Linux and running Linux makes the journey easier.

I've tried Linux many times and I just can't get into it. The biggest drawback is the lack of serious DAWs (Digital Audio Workstations, if you didn't know) and gaming support (I don't think my PC could handle running anything smoothly through Wine).
