Don't know since i don't have P model. But i think (maybe i'm wrong) Extremely can't work cause of "boot.img" file ...

You can try it if you make a full backup with TWRP, in case of issue, you can restore your current ROM.

Great rom! Thx!

One question: is it normal that the big cores are offline? Well, they seem to be, according to Kernel Auditor and other apps.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, it is normal. The big cores are fast but they are bad on battery usage. So, it is normal that the small cores are used most of the time and the big ones only come into play only during very high CPU demand.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] choice2rejoice:
Well, I just played some games, Snowboard etc and not even than.

But they are enabled?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, they are. If you run Antutu 3D Benchmark, it shows CPU speed of 1.6ghz. Only the big cores run at that speed. I use Nascar's Raceview to watch the races. It is a virtual rendering of the race using GPS info from each car. It must be using the big cores 'cause it runs the battery down in about three hours.:(

Verification Failed

Hi Guys,

I have TWRP installed already and working fine. I flashed the ROM, when it reboots says "Verification Failed" . It then suggests to do a factory reset and if I do takes me to TWRP with quite a few "failed to mount /Data"?

What is going on? I can't use it now.

UPDATE:

Found solution to this issue.

I just followed these steps suggested by Shameera_N - in this post: https://xdaforums.com/galaxy-s5-neo/help/verification-failed-unable-to-restart-t3633942

1. Reboot to recovery.

2. Do a data wipe (WIPE>FORMAT DATA) And Say "Yes"

3.Go to Reboot and Reboot back to recovery.

4.Download DM Verify Disabler https://build.nethunter.com/android-...y-opt-encrypt/, Get the latest.

5.Copy in to the phone and flash it.

6.Go to Reboot and Reboot back to recovery.

7.Now Flash any rom as you wish.

8.Make Sure to Wipe Dalvik, Cache after.

All good now! Now it's time to enjoy this ROM! :)

Thank you
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Congratz ... but ...

Or you can just follow instructions provided with Extremely rom ...

And Disable Encrypt is not needed since SuperSu or Magisk own it natively ...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Update_(SM-T580)(SM-T585)(SamAppz)(OffBootFile)

Informations on update:

Extremely_v4.0bT580 updated [T580XXU2BRB2] security patch 20180201

Extremely_v7.0bT585 updated [T585XXU2BRB2] security patch 20180201

OffBootFile (Official boot.img file) updated to handle new rom versions.

SamAppz with actualized version of APK from latest Samsung firmware. Last available version of Youtube (nopub, back ground play) from [MENTION=3279788]ZaneZam[/MENTION]

Installation / Upgrade:

Install extremely rom corresponding to your device following the OP instructions (first page).

Upgrading, simply apply installation from TWRP, no wipe needed. If you're a Magisk's user, you need AFTER the FIRST boot, enter TWRP and following steps described below (Installing MAGISK)

Installing MAGISK v16.x

Install Extremely rom like always following OP and let the device rebooting normally at least 1 time before next step.

You must use "Exmely_bT580_bT585_OffBootFile.zip" (download section) with TWRP and ( WITHOUT REBOOTING ! ) install latest version of MAGISK followed by Busybox if needed (choose *ARM.zip file). So, you must put all needed files in your extSdCard before starting operation !

Why using SuperSU 2.82 instead 2.82SRx

Simply because when i use others latest versions (SR2, SR3, SR4, SR5), i have a big lag on login screen (schema) and i don't like this.

You can install latest version of SuperSu without any other issue ... (if you don't use lockscreen).

Notices:

Exclamation mark get you bad mood ? read this.

What "Exmely_bT580_bT585_OffBootFile.zip" do ?. This patch simply put back the original boot.img file (stock) that permit a correct installation of Magisk, don't forget to not reboot between steps, if not, your data's partition will be erased and partition will be encrypted again. In this case, you need to format it in TWRP.

Each update erase apps installed with SamApps, it's a normal thing, you just need to put them back with it, your generated data with these apps still present except if you delete "data" directory in TWRP.

If multi-users, was previously enabled, it will back to disabled, you'll need to apply the patch again, your others accounts remain present with their owns preferences.

Hi [MENTION=8022634]luattic[/MENTION],

I've flashed the update and let it boot fine the first time.

Then back to twrp, i've flashed offbootfile and Magik 16.

When i reboot, it gives me a black screen, not even the samsung logo.

I've tried many times to reflash, same result.

Anyone else having this problem?

If needed, what log can i provide?

Edit:

I can't access to TWRP anymore, only Download Mode.

Edit 2:

Reflash TWRP via ODIN, and reflash ROM, no more stuff.

I'm waiting for your advice :)

Thanks in advance.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dorf18:
Just try rebooting when you get black screen. Hold power volume down and home until screen goes blank then let go. Had same issue with RR build. Booted fine after reboot.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] bc1977:
Thanks, but it didn't work.

So i ended up clean flashing and it was good.

So i tend to say that dirty flash + Magisk isn't a good idea.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Hi,

Dirty flash + Full Boot + Reboot to TWRP + OffBootFile + Magisk16.0 + Full Boot + latest Magisk Manager, has worked fine for me;

Have you optimize your system ?

Nougat need more ram than marshmallow, in case, i've 850mb free usually (950 just after booting).

Not implemented by Samsung but you can find some tweaks to add it (i don't know if this work on nougat, cause i don't use it and i don't want to use it ^^)

Had to remount system but got everything mounted. Wiped everything. Went to install rom and 2nd file, got error 7....... Foolishly hit reboot now won't go past boot screen.... Help... Thanks

Yes I have a t580 Galaxy tab a 10.1 wifi only no spen
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Why remount system? where the installation procedure do it herself...

For the 1st zip, do step by step the installation process described in the main thread ... Wipe "system", "cache", "data", "dalvik/art cache" it's all, and Install it. Don't try other things like mounting something or other kind of nothing !

reboot system normally after 1st zip installation, and after configuration, restart device to TWRP and flash 2nd zip file.

2nd file may be corrupted try to dl it again, to test it, just unzip it to a blank folder, if you haven't any error when unziped it, it's ok, just flash the zip file.

If error occur please give me more precisions, write here the exact error written with the 7 number.

your explanation look like some shaked words into a turning bowl ...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Darth#Mike:
Sorry was typing faster than I thought. Ok so maybe just a bad download? I've already wiped and can't get back into anything past boot logo so I'm going thru Odin to attempt to get it started again. Thanks.

Ok. This was entirely user error. Got it figured out. It's booting now. When I first went to wipe system, data, cache, dalvik, I got an unable to mount error, so I tried to fix that. But I retraced and undid what I did and now it booted up. I apologize for the wasted time. Thank you very much.

I just flashed the rom on a new device following the instructions closely. After the logo the screen goes to black and it reboots to TWRP. Tried to flash multiple times, result is the same. How could I fix this?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Hi,

Need to know:

which device / rom.

Checksum of downloaded Extremely's rom correspond to original ?

TWRP version.

Full detailed procedure.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] poisonborz:
T580, latest Extremely, checksum matched (I always check), twrp-3.2.1-0-gtaxlwifi.img

Vanilla device.

As per OP I installed TWRP via Odin, [Wipe]/[FormatData], [Wipe]/[AdvancedWipe], rom flashing.

I had the same issue as #569 - verification failed. I installed dm-verity as suggested there.

After that, at system bootup there's only black screen after the Logo, and reboot to TWRP. Tried to flash rom after that a few times with wiping but same result.

Meanwhile the rom Ultra Lean Nougat V7 installed without a problem.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] stonypass:
Luattic, thanks for the update I installed it last night and it's working great.

It did fail zip verification in TWRP, and I thought I had a bad file so I downloaded it again.

Thought verification worked when I had installed the 3.0 update but maybe that's not correct, or I missed a step. Thanks again for your efforts, it's a perfect ROM for this tablet.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] soaringowl2145:
As long as the checksums match you should be good.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
Hi,

Into TWRP you have an option to check zip signature, you need to disable it.

[Settings]/[zip signature verification] unchecked this.

I hope this solve your issue.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] luattic:
You missed something, I do not know what it is but there is no doubt, you should not use dm-verity because the ROM contains original SuperSU and this function is already integrated and active.

The procedure for formatting the DATA partition appears to be done correctly. Normally, once installed, this ROM must restart once after the logo, but not in TWRP, it will display the Samsung LOGO again and launch the welcome screen with the information request for the Nougat configuration.

I personally use TWRP 1.1.1-0 but must doesn't affect installation process.

ULR_V7 use the same processes for installation except it bundled with MAGISK for root function.

Thank you!

So I have been following this thread for almost a year. Eally had my eye on this tablet as an affordable alternative. I must say your directionz, your work is excellent! I love how easy evrything was to install! Flawless work, I have not run into a xingle bug or issue with anything. Thank you!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] alisterwh:
hollo guys

just a few pieces of feedback and toughts here, after testing the rom in my PHE (spanish) galaxy tab A sm-t580.

1 - I have the solid sensation that the tablet runs faster, so the debloating process, and probably the fact that storage is not encrypted, totally made a difference. Thank you!

2 - since I prefer to use google AOSP vanilla/original pixel/simplest possible apps and the like, I have removed samsungs original "my files", "gallery", "music" and "camera" apps, replacing them with things like an old (android 7.0+) version of the original pixel's camera app, SimpleFileManager, SimpleMusicPlayer, and SimpleGallery. One of the consequences of not using Samsung's alternatives is the fact that Private Mode becomes totally unusable. So, I dont know if it could be very hard to achieve, but it would be great if I could remove private mode from all the preferences menu, the notification bar widget, etc. In fact, at some point of my modification process, the private mode switch became totally impossible to enable (maybe its because of the lack of compatible apps?). If someone can point me in the right direction to remove references to private mode, I would be so grateful.

3 - I like to integrate all the "updated" system apps into system again, using app management tools like Link2SD. I have painfully discovered that "google play services" SHALL NOT be integrated, because if you do so, google play store totally breaks, becoming unusable (it opens and closes in a fraction of second, and nothing that I have tried recovered the normal function of the app so I had to rollback). Not quite sure if this is an issue with the rom, and I guess it's not, but I would like to mention it should someone could shed some light to this mistery. it's the only app which updates I have found impossible to move to system.

Hi,

I don't know yet, currently I haven't had any warning from GPlay about the validity of the ROM.

If someone got this, please let me know your software configuration. Mine is:

Rom: v4.0bT580

Root: Magisk 16.0 / Manager 5.6.3

Recovery: TWRP 3.1.1

GPlay: Options / Store v9.2.11 / Certified !

I dirty flashed the new version without problems.

I use Magisk instead of SuperSU. Therefore I flashed via TWRP in following order without reboot:

1. Extremely ROM

2. Extremely OffBootFile

3. Magisk

4. Busybox

...final reboot

---------------------

Ich habe die neue Version wieder problemlos auf mein T585 updaten (dirty flash) können.

Da ich aber Magisk statt SuperSU verwende update ich via TWRP immer in folgender Reihenfolge:

1. aktuellste ROM Version

2. OffBootFile

3. Magisk

4. Busybox

..reboot und fertig.

Hat bis jetzt immer wunderbar funktioniert.

Extremely is not an official samsung rom, but based on latest version of it, If you want to use it you need to change bootloader to TWRP following instructions described in first post. I prevent you this, is not a normal update, do it carefully and don't do it if you don't know what you really do.
