Yeah should be sweet to flash my customers was the cellular model and wifi 16GB maybe the 32GB is wifi only, but

The same firmware can be flashed .pit is the same just means that the cellular data in the firmware wont be flashed to the partition as the partition wont be there so it just skips and moves on to the next available partition to keep flashing if that makes sense,

But with any other model Samsung always make sure it's the correct firmware code and binary as the wrong .pit can permanently brick your device luckily Odin has a fail safe that will fail it but there are patched versions of Odin to flash any unnasigned file so avoid using prince comsys Odin or odin3 3.13.1B the letter B means its patched if its 3.13.1 only its official :)

And yeah I'm off to bed now Haha all good mate glad I could share some information I'm like an encyclopedia sometimes Haha
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
I worked for Metricom when I was younger.

I helped create and support the first wifi network that extended from coast to coast in the US.

things were alot different though, and we work almost exclusively with windows PCs, the linux people basically did all the linux support, I helped organise their files for them but thats all i had to do for them.

I had a SCO box in my living room back then but never did learn much about it.

believe it or not.

the first fully mobile devices were actually made by compaq, and the modems that were used were made by qualcomm.

seems like ancient history when you have done nothing for 17 years now.

when Nafta was created they sent my job to India, though it was supposed to be unskilled labor only.

then after a 5 month Hhiatus they called me when the plane hit the world trade center as it messed up the landlines and cellular fell apart too. They didn't want to have to carry up 500 sheets of paper (1 full ream) per casualty (approx 3500) 100+ stories on the back of the fire department.

I gave some info to a coupel of the head admins here, enough that they could piece together exactly who i am and that my words were correct and true, funny huh?

I really did that.

whats more when Qualcomm sent their reps to our office in Atlanta Georgia (on circle 75 in Cobb County) they couldn't make their own device work, and my supervisor John Brundridge (i think i might have mispelled his last name..) brought their laptop and device to me and I fixed it.

they didn't know to hardcode the DNS in the network adaptor settings as if it were a modem because it was a NIC.

who would know that but the one that did it?

computer networking was always my thing, Cellphones are not, but little by little I am getting over it.

times change, technology has as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
You know Matty, the unlock option didn't show after 7 days as I had previously tried setting the date forward, then after 8 days it still didn't show, so i took it and set it to auto adjust, that wasn't enough to cause it to show OEM unlock, but then I decided to reboot and connect to the internet with it set to auto-adjust and it showed immediatly at that time. Just a side note, in case anyone is confused and trying to get it to show, auto-adjust and a wifi connection are your friend in this regard, but at that point you can't skip the 7 days in truth.

so anyways I am about to root the first tablet and see what I think of it. Wish me luck.

(this post was really about the OEM unlock feature).

Edit: I just realized all you had said about magisk was to start it to install the zip, but I am unsure how to, so I guess another 24 hours will have to be. I don't understand the magisk thread.

how do i install that zip?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate sorry i havent gotten back to you,

Thats a handy little trick to know regarding the oem unlock i didnt know that :),

Your question about magisk are you wanting to know how to actually flash the magisk.zip for root ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate sorry been busy shops been packed today,

Did you have oem unlock ON when trying to flash TWRP in odin ?

What version of odin are you using also ?

No dont extract the magisk.zip leave it as it is just place it on the sd card dont worry about the noverityencry.zip magisk comes with this prebuilt into it,

Then power it off once oem unlock is ON and only when OEM unlock is ON,

Open odin, go to options and uncheck auto reboot,

Flash TWRP to the tablet, to do this place the TWRP_RECOVERY into the AP tab of odin,

you should be using ODIN3 3.13.1 latest by the way,

Press start and wait for pass in green,

Do the manual reboot but as soon as the screen goes black while still holding the home button from intiating the reboot combo you MUST VERY QUICKLY

Change only from power and volume down to POWER & VOLUME UP while still holding the home button the entire time but DO NOT let it reboot to the OS its alot easier,

TWRP now boot, dont swipe to allow modification unless your installing a custom rom also, if your just using stock tap the button above it,

now very IMPORTANT go to the wipe tab, select the format option, then type yes, then enter after tap wipe cache/dalvik,

Then go back to the main menu and select reboot,

Then tap reboot recovery,

Wait for TWRP to be rebooted, tap the tab at bottom right to see if the data partition is mounted, once it is go back to main men and tap the install tab,

Now select storage and then SD card,

Now select your Magisk.zip and tap start wait for it to complete flashing, now wipe cache and dalvik then reboot

You should now be rooted with magisk, once the OS boots, you will notice a new app called magisk manager,

Open magisk manager, go to settings then enable the following,

1# Magisk core only mode (reboot required)

2# Magisk hide

3# (optional) systemless hosts

4# Repackage Magisk manager with a random name.

After youve done this reboot the tablet (this is a must), once rebooted enter magisk manager again and select magisk hide from the menu and select all the apps you need to hide root from.

Thats it all done, now youll need to install busy box.apk and install to place all 364 of busyboxes applets into the system Xbin which requires root privledge to do so,

i use meefik busy box 1.28.3 personally as ive never had a problem with it ever,

To check if everhthing is done properly id suggest to use root checker.apk this tells you the following

If your device is rooted properly,

Safety net check passes or fails

Busy box is installed correctly

Also has a device info section aswell that you can use to check device info
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
yeah, OEM unlock was on 5 out of the 6 attempts.

i was using ODIN3 3.13.1

autoreboot was unchecked.

https://androidfilehost.com/?fid=889964283620778312 << the file i used in the ap slot (from the first post in this thread).

I followed the instructions provided but it will not accept it for some reason.

I followed exactly what you posted, it didn't work, so then i looked at the other thread by Mingkee and that got me a little further as i wasn't fully in download mode on the first few attempts, the later couple though were.

I reached out to a local here that uses the forum and maybe he will be able to make a few minutes to come see and help, after all it shouldn't take but 30 minutes. Long trip for me but thats ok. (Los Angeles is actually a huge area).

it fails on TWRP flashing repeatedly.

I think I am gonna take me a trip to Hollywood so I can buy some marijuana, I always work best when I have been smoking, will probably help a little with stress anyways.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Acogu:
You need USB debugging ON too.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Shouldnt need that on to flash TWRP,

All that is generally required is OEM unlocking for the bootloader,

Download mode runs off of its own indipendant diag port specifically for just flashing, usb debugging has nothing to do with this as far as im aware, i also had no usb debugging on when i flashed it to a customers 8.1 oreo tab flashed every simgle time just wouldnt boot past galaxy logo and messed the system up as my system was 8.1 but his is nougat 7.1 so should be no problem,

The only thing i can think of is the device isnt an actual GALAXY TAB A 8.0 T380/5 and possibly a tab T350/5 that is the only thing i would say it would be if its not flashing the recovery
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
USB debugging was the only other option that was on, on one attempt it was off to see if it would make a difference, which I doubted to begin with, at least that part didn't let me down by letting me down, i expected that to fail.

What a day, I have been through the ringer I gotta tell you.

a little smoke goes a long ways.

it sucks getting old.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Whats your tabs model number mate ?

Is it a T380 or T385

Or T350 or T355
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
actually my last tablet was a 350, I gave that to my sister a few months ago.

my 350 was "smoky titanium", both of the 380's I own are black.

this is a 380 (2 of them actually)

https://photos.app.goo.gl/dv7rtPYSKDZqxS738

https://photos.app.goo.gl/mYvePruF5o3mxmLS7

2x380's.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
whats your "AP SWREV: like in download mode are they S1 R1 K1 B1 for example ? As they should be,

Download mode will also display your model number also at the top in the writing on the left,

Also is there anything in download mode stating RMM: prenormal or Abnormal ?

---------- Post added at 03:22 AM ---------- Previous post was at 03:16 AM ----------

Ok yeah thats weird, definitely T380 then i notice yours is the 32GB version my customers was 16GB but that shouldnt have anything to do with the recovery being flashed systems are identical,

Can you provide a picture of your download mode and you developer options screen in settings for me

Ill be able to tell if anthing is wrong from the pictures
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
I'll append further photos to this post to avoid too much clutter, almost is already.. sorry.

https://photos.app.goo.gl/cscuRDP6nn8CBNn68

it just took..

wtf..

I did it all exactly the same..

swear to god, hold on, ill send the rest of the links and images..

now to get magisk installed and running..

https://photos.app.goo.gl/FkFrSZxLFuDt8uXw8

https://photos.app.goo.gl/QnSGxy9zMpKPAMoR7

https://photos.app.goo.gl/6ugjqTYAz9Jtvfa56

The ONLY difference.. was that I was smoking Marijuana before I did it this time..

got Magisk and MM on SD Card, so I gotta open that post in another browser.

how do I get TWRP to come up to allow me to install Magisk?

It passed, disconnect it and reboot the tablet first?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Perfect mate there you go,

Make sure you do the button combo to reboot to TWRP quickly and correct the firt time dont let the os boot,

Once it boots TWRP follow my detailed steps and you'll be golden :)

Always look in download mode and where it says OEM lock make sure that is off in download mode, glad its sorted mate
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
i couldnt get it.. os loaded on me..

wipe the system?

flash stock rom?

OEM unlock is missing again.

i think ii is bricked, saying only official binaries are allowed to be booted..

what now?

It looks like try to install TWRP again, it booted, i went into dev options, oem unlock hidden, flipped auto date/time, rebooted, went into settings, oem unlock showing, trying again to see what happens.

OK, I have the unmodified system partition screen on the TWRP screen, with a big lock showing on it, i don't understand what button your refering to.

ok, first swipe unlocks it and then there are 2 bottons and another swipe, I believe you mean select keep read only, tapping it
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Are you booted into TWRP ?

If so send a pic of the screen ill tell you what to do,

The button combo i was talking about also was only to enter TWRP after flashing the recovery you must have not done it correctly the first time which is why you needed to flash stock back and start again,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
yeah, i figured as much :(

just the ap slot?

yeah, screen looks a little funny and didn't get all the icons back, just have to sort it out as i go, no biggie.

This has been a fantastic learning experience, this isn't scary now knowing how to get it into recovey and all..

7 days.. what is 7 days?

Thanks man, you have been awesome, I know the next attempt will succeed, but I really wish I had takens pictures as I went from start to end so we could have had that for a better more concise guide, rooting for dummies, by dummies.

this is one of those times that failure is greater than success :D
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate

No i meant did TWRP load after you flashed it and rebooted ? You need to format the data before usimg TWRP to install magisk, to do this when TWRP fist loads to the main screen,

Tap the wipe tab, then tap the format tab,

You will now be promted to type yes for format once the data patition is formatted a tab to wipe cache and dalvik will appear tap it,

Now return to the main menu and tap the reboot tab, then tap the reboot recovery tab, wait for TWRP to reboot,

Tap the install tab, then select your SD card storage and find your magisk.zip simply install, once again a tab with wipe cache and dalvik will appear tap it then return to the main menu, then reboot and then just normal reboot tab now,

Once the system has rebooted your now rooted and magisk manager will be in apps do all the necessary hide and what not as i mentioned,

If you notice your settings menu is a little messed up just flash and start again its actually something in the debloater script someone mentioned to me that causes the settings menu to be jumbled and look weird, i have also had it happen a few times with magisk and have been able to clear it up reflashing and doing it again
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
it was demanding the original rom, so i gave it to it, seven days..

I am ok with that, really i learned alot out of this, bet i can get it accomplished next time.

I'll try to keep it in PM with you next time maybe, but I am literally 98% sure I can get it next attempt.

maybe I didn't understand all of it, but thats ok, I still learned a great deal in it.

first and foremost, don't sweat it, it can be reflashed stock and started over, that takes the stress out of it actually.

says I am running low on space.. it's a 32 gig, this is weird.

storage settings is showing it as an 8 GB device.

factory reset?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
No worries mate, glad youve got it sorted

Your storage issue is due to you not formatting the data partition with TWRP samsung is encrypted staright out of the box TWRP when formatting decrypts the storage for use,

Once you do it right everything will be normal, if anything goes wrong just flash back stock and start again

Hi [MENTION=4899305]ashyx[/MENTION]

Any news on this? Not pushing mate.

Cheers,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
I cant get twrp to load, did everything exactly as i did last week..

i gotta tell you, after months of this it begins to be despairing really.

I just don't get it, the directions don't work right, too much left out..

to make it work you have to take part from one place and part from another and put ti together and that doesn't work either, there's no single STRAIGHT source of info.

another week..

i need someone to talk me through this on discord or something, this isn't working..

using that date and time adjust and rebooting back into normal mode i have reset the oem unlock and managed to get back into twrp, finally.. but the format isnt taking.. third time, keeps coming up "unmodified systems partition", third time now.

I am leaving it open to the wipe settings..

any ideas?

next week i guess..

I really need your help real time matty, or someone..

I seem to have gotten TWRP installed but magisk messed up somehow, the OEM unlock is hidden so I am gonan stuff this tablet back into storage for 7 days until the OEM unlock shows again, right answer right? I mean so long as I get the OEM unlock to show up again I can always reboot into TWRP and then reinstall Magisk from there, i think i instaled the zip when it should have been the APK i think.. but still, TWRP is in and running, says it needs updated, i am just gonna ignore that part though.

Edit: wrong again, magisk manager is there.. what to do now? nervous over the oem unlock missing.. stashing it for 7 days cant really hurt can it? Magisk reports it is installed, waiting game now, seems done.

funny part is i messed up and had to reset and readjust the time as i described earlier and i managed to go in re-unlock the OEM unlock and continue attempting rooting the device, and won.. thanks to that little trick.

Titanium backup downloaded and installed, granted SU.. worked.. done.. 7 day waiting game now for oem unlock is all thats left, thank god.. and you guys too, hard to beleive it took like that, i thought for sure i was going to have to re-flash stock rom.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Finally got the OEM unlock option so I went straight to the laptop to do the TWRP install. Got download mode going, got the TWRP_3.2.1-1_sm-t380_15118.tar file in the AP slot, with AP checked, auto reboot unchecked. When I hit "Start" all I get is "<OSM> All threads completed. (succeed 0 / failed 0)" and nothing happens. Nothing starts. On the ddownload mode screen, I see FAP and OEM locks both "OFF"

This is on Odin 3v3.13.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Id assume youve got the latest samsung driver.exe installed so,

You should notice when your device is in download mode when you plug it in with odin open, you will see added in the white dialog box aswell as new commport appear in the top, if nothing shows its a driver, dodgy cord or usb port on the tab or pc,

Also place the TWRP in AP tab when flashing aswell just in case your not sure
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
if it is still rebootable back to stock i would go back into developer options and make sure it is unchecked in there, if not reset it by connecting to the wifi, going into your time and date settings and unchecking autodetect and then set your date forward a day and then recheck autodetect and then look under developer options and OEM unlock should reappear, thats how I used that to break out of that cycle. Then I woudl shut the tablet down completely and then hold volume down and power to get into download mode.

hope it works for you like it did me.

once you get a pass you can't do that though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hes got oem unlock and frp lock both off as are displaying as off in download mode,

Also in the info he provided there was no successful 0 failed 1 it was "successful 0 failed 0" which leads me to beileve that no connection was being made to the device,

He/she should only have to do that if the flash was initiated, i dont think it was in this case though,

Did you get my pm also about how to do magisk hide also ? I tried to make it as simple as possible for you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
I didn't get the PM.

I wasn't too overly worried about hiding that I did it really, I have another tablet that I didn't root that I can use for anything that I cant do on the one I did. I have been tinkering with it and seeing some of what they lock you out of, that being the case you might be right, should probably mask that i did it in case i end up doing the same with the other.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Got it going now, I just flashed the TWRP in Odin, rebooted to TWRP, flashed Magisk. Do I need to flash the "no-verity-no-encrypt_ashyx.zip" if rooting with Magisk?

Currently in TWRP, haven't booted to OS since this started.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate no need to flash the patch magisk comes with this now :)

---------- Post added at 03:03 AM ---------- Previous post was at 03:00 AM ----------

Oh wow reall, not sure what happened there then,

All good glad its sorted, if you wanna use magisk hide just go to settings in magisk manager and enable it and the one above it,

Then reboot the tab, then go to magisk again and tap hide instead of settings this time and whatever app you want to hide root from just tap the app and its selected to hide root, id reboot after course just to make sure the hide takes effect
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Now I am getting a "Verification failed - Unable to restart your device. The integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data" when I boot. I did not flash no-verity-no-encrypt_ashyx.zip.

I can boot into TWRP. In TWRP, when I try to mount storage, internal shows (0MB) while MicroSD shows normal (59246MB).

---------- Post added at 03:16 AM ---------- Previous post was at 03:06 AM ----------

I kind of expected that the device would be/need to be wiped after the bootloader unlock anyway. I don't remember ever rooting a device that just carried on the way it was with the addition of root. Before I reset using the reset on that screen, I want to be sure that there is not another way around this. If I lose TWRP and OEM unlock, I will have to wait another week.

One more week without AdAway is going to be rough.

---------- Post added at 03:31 AM ---------- Previous post was at 03:16 AM ----------

Took a chance and flashed that no-verity-no-encrypt_ashyx.zip file in TWRP. Plobby messed up. Hanging on "Samsung" screen. Feeling like a bootloop...

---------- Post added at 03:38 AM ---------- Previous post was at 03:31 AM ----------

And this is a bootloop. Long pressing on power does nothing. Held it for at least 20 seconds and nothing. Tried other key combinations to get into DL or TWRP...just hangs on Samsung splash screen.

Trying adb...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
You didnt format the storage as you were supposed to as soon as TWRP boots this is a critical step before installing magisk,

See if you can get back to TWRP,

go to wipe tab,

Tap format tab

Type yes

Tap Wipe cache/dalvik

Back to main menu,

Tap reboot,

Reboot recovery

Wait for recovery to reboot,

Tap install,

Then install your magisk.zip

You dont need to flash the no verity encryption either this is prebuilt into all magisk latest versions
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Ok, so I did get it to go back into TWRP. All is not lost. Factory reset in TWRP. Let's see if it boots. Nope! Bootlooping again.

I guess I need to flash the ROM. The SamMobile site has several options for the device, but not my region. There are even 8.1 ROMs on there. Which one to choose for USA? https://www.sammobile.com/firmwares/galaxy-tab-a/SM-T380/

---------- Post added at 03:54 AM ---------- Previous post was at 03:47 AM ----------

Having a hard time getting the key sequence right to get from bootloop to TWRP...I know it is PWR, VOL UP, HOME. But in what sequence of pushing/releasing?

---------- Post added at 04:00 AM ---------- Previous post was at 03:54 AM ----------

Done. Upon reboot to system, I am still bootlooping. I may have screwed up with the no-verity-no-encrypt_ashyx.zip flash.
