I'm not sure what I'm doing wrong.

I downloaded Odin 3.11 and - in download mode - installed TWRP 3.0.2-1.

Then, in recovery mode, installed SuperSU v2.74 (Beta) and wipe.

After that I have experience:

-1 Eternal boot (+30 minutes)

-Normal Boot but SuperSU says the SU binaries aren't installed.

I do see some kind of error in the installation with TWRP

When I flash the Stock 5.0.1 Firmware, root with autoroot works. But with the stock 6.0.1 it fails...

Again, no idea what I'm doing wrong.

Edit:

Ok, I found my problem, TWRP was in system read only mode!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] A Ham Sandwich:
I have a couple questions:

I'm on a modded HTKO+ 5.0.2 ROM on my T350 (From ashyx's forum listed in OP). The tablet's unlocked, rooted, and TWRP. Do I need to downgrade to stock 5.0.2 FW before installing stock 6.0.1 FW? I'm worried since KNOX counter is ticked already, that I may get locked out by installing stock Samsung FW. My device doesn't *technically* have official 6.0.1 update available since I'm in the USA, and also running this custom ROM doesn't allow it to see official updates so I don't know if it truly meets the criteria in step 1.

Or does step 1 simply mean, if there's an update available for the tablet anywhere, then download that?

Last question, where is the link to Stock_Marshmallow_ROM_SM-T550_T350_Deodexed_Rooted_Knoxless_V1.1.zip listed at the end of your post??? I've gone back several pages in this thread and checked out the first page and can't find a link to this anywhere.

Guys I think it's time the Tab A and Tab E got its own forum on XDA. It's becoming fairly popular now there are the new models as well as the old.

However we need to request this to the admin.

The more that request the more likely it will be that XDA will create a forum for it.

http://xdaforums.com/showthread.php?t=1660354

If you do request don't just say you want a forum for your device.

Put a few lines as to why it's needed and be polite about it. ;)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
First; My device is also T350/XAR, USA one too. If you don't have official tar file, here you can download it from this link.

Second; you have to flash official 6.0.1 tar file back to your device using Odin (please make sure you know how to use odin)

and lastly, once you are on 6.0.1, you need to get TWRP flashed...and once you are on 6.0.1 and TWRP installed, then flash my Stock_Marshmallow_ROM_SM-T550_T350_Deodexed_Rooted_Knoxless_V1.1.zip

hi [MENTION=4899305]ashyx[/MENTION]

so I switched back to XAR/USA firmware of my TAB A T-350. Previously I was on UK version and of course used twrp_3.0.2-1_sm-t550.tar version.

Now, finding something strange I can't able to get twrp_3.0.2-1_sm-t550.tar work on XAR/USA firmware

I doubt there could be different between UK and USA firmware...

what do you think?

twrp-2.8.7.1 doesn't work?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
Well, that's where I am a bit confused about it. Your twrp-2.8.7.1-t350.tar version we used for Lollipop, should be also working with MM too?

I am not sure between Lollipop recovery and MM recovery if any differences, if there's some, even if twrp-2.8.7.1-t350.tar flashes OK, not sure if it does anything...

do you think using twrp-2.8.7.1-t350.tar on T350 MM would be OK?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
It will flash fine, no reason why it shouldn't boot and be fully functional.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
I actually just tried now, a few mins ago..it flashed twrp-2.8.7.1-t350.tar , it worked...then flashed my custom stock base MM ROM T350, it seems like it flashed OK, but stuck on Samsung Logo.

I know first boot takes quite long time 15-20 mins, but I have feeling it will stay with Samsung Logo..

assuming TWRP flashed all good, then probably something wrong with my build, suspecting the boot.img...

funny though, did not have these problems with T550 build...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I take it you have disabled dm-verity and encryption in the ramdisk?

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
i found the issue, I did some kernel tweak, which it did not like it...so I removed and repack boot.img, and it flashed OK.

with that said, I can confirm twrp-2.8.7.1-t350.tar works OK for T350 MM..

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
Keep in mind [MENTION=4899305]ashyx[/MENTION] most likely right, it may require P350 Kernel, and using T350 Kernel may not work, but if you're feeling adventures, here goes:

I wish I had P350 or P355 (4G/LTE) version, since that version of 8 inch not available in USA, and the ones I found on ebay they are asking crazy price for it..

If you like to test my MM ROM for T350, here's the download link: download

My MM ROM - JazzEspresso_SM-T350-6.0.1-MM-V1.0 - is work in progress, so keep in mind that. I did include SPen stuff from latest firmware SM-P555L 6.0.1, so if you lucky, your SPen probably functional using my T350 MM ROM.

For me, since my device is WiFi without Spen, I can trigger SPen all good, but can't interact with it since, probably, it may depend on actual SPen or Samsung probably remove "finger" interaction in latest MM firmware..so but I have feeling if you use my MM ROM, your SPen may still working OK (if it did, please do confirm).

remember the instruction I outlined at post #527 , please read that...

p.s: it has 4-Way Reboot MM included, plus some other features...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Osmodiar:
The specs of both T350 and P350 seem pretty much the same. The difference is the S-Pen. Now, the s-pen is not just a piece of plastic used to touch the screen. The tablet detects after getting it removed, it has a button that triggers Air Command functions for S-Pen and you can also see a tracking point when it's close to the screen.

That said, makes sense that a different kernel is required.

But I downloaded your version. I have a full stock rom backup. Now I need to get the time and courage to flash. I don't want to make promises yet because I'm still hesitant...:eek:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jazzespresso:
kernel could be a bit different between t350 and p350, but I don't think it was too much differences, worst thing happen it would flash and stuck on samsung logo..then you can always restore it from your twrp backup..

by the way, my MM ROM t350, download it and unzip it go to META-INF\com\google\android, open updater-script with notepad++ and change top part where it says "gt58wifi" to yours, I believe it is something like gt58notewifi for P350, can't remember now...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
The kernel will likely boot but I envisage touch screen issues as I think the driver is different.

This is the case with the 9.7 model.

Also no need to change the device name as the recovery for the T350 (does this work on the P350?) will identify the device as a gt58wifi.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Osmodiar:
Well I have to say that touch screen is terrible when not using the S-Pen. Seems to be set with very strict precision, some things are impossible to press with the finger.

I installed TWRP for P355 as you recommended instead of T350. Up to now is working fine.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] A Ham Sandwich:
What version of Odin3 are you running? I use 3.10.6. Did you open Odin3 by Right Click > Run as Administrator? Make sure that Auto Reboot is UNCHECKED to flash TWRP, or if it is checked be prepared to use the Recovery button combo immediately when the device reboots from the flash process. Otherwise, once TWRP is successfully flashed in Odin and it's still in download mode, disconnect the USB and manually reboot directly into Recovery mode (Vol Up + Home + Power until screen turns on) for the first boot. Then restart the phone like normal. If you skip this part, the recovery will revert back to stock so the first boot must be directly into recovery mode for TWRP to stay installed.

Yes, I figured it out, I just went back to 5.02 and used twrp for t350, and then used cf auto and went that route for now. I'm still figuring out 6.01 with root, the more I play the more I'll get, but thank you all for the help and suggestions ??
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You need to boot to recovery immediately after flashing twrp otherwise it automatically gets replaced by stock recovery. It has been posted several times in the thread. You can search the thread using the search box.

Set odin for manual boot(uncheck Auto-reboot) , then use the 3 button combo to boot to recovery after odin finishes flashing.

Status of Evervolv for SM-T550

Hey guys not sure now many T550 users there are but i just wanted to let you know that i have gotten Evervolv building and booting on it. Currently working with [MENTION=2219132]elginsk8r[/MENTION] who is building it for T350 we have made a shared common repo for the Tab A devices as well as a msm8916-common repo that the Tab E and others could use in the future. We have also combined the kernels into 1 shared kernel using a caf base which is a lot cleaner and easier to update then using a stock based kernel. Both of our devices are wifi only, but once we get them stable i will work on supporting the LTE variants with testers. (Please do not request to be a tester i will reach out first) We do not know if the S-Pen variants are supported out of the box because they most likely have a different touchscreen. Proper support for them will come once our variants are stable same as the LTE variant. I will be releasing a download for the T550 soon.

What's working on T550 and T350:

Touchscreen

Power, Home, Recents, Back buttons

Wifi

Bluetooth

Camera

Sensors

GPS

Storage's (internal, external, adoptable storage)

Bugs/Not Working:

Initial setup takes a while to initialize

Audio

No need to be sorry! You tested alot of things that helped ash with the root and recovery!

Ashyx, as for the mount issues.. That is common in cwm or philz. I get those too on my phone with cache not mounting. Twrp has always worked flawless. So shouldnt system, boot, and the rest be OK to flash with? In the past to fix the mounting cache issue, I always had to restore my backup of cache then reboot into recovery again (full restore since just restoring cache won't work). Never had errors with cache after doing that except not being able to wipe it (would freeze on wiping cache). So when I flash roms, I use flashfire to wipe the cache instead of using philz or cwm. That's what I had to do on my phone (zte source). I'm not sure if twrp can solve those issues but I always had the cache not mounting on philz or cwm recovery. That's what I've experianced

[MENTION=6252874]amritanshu001[/MENTION] From what I've read reflashing the firmware does not reset the knox flag. I did some research on it, and the Knox status appears to be set by something called an 'e-fuse', once tripped there is currently no way to reset it. As far as warranty goes it may or may not have voided it; it just depends on where you live. As far as which countries a tripped knox voids the warranty and which it doesn't I couldn't find a reliable source of information. There's a thread around somewhere where people posted their luck.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] amritanshu001:
[MENTION=5711775]TheMaskedHamburger[/MENTION],

Yes, i myself did some research on Knox counter. on Snapdragon chipsets, there is a hardware fuse that gets set in case of customization, where as on samsungs own Exynos chipsets, its a software fuse that gets set. The software fuse can be reset, however hard that might be. However, there is no way of resetting a hardware fuse [well, unless you know about chipsets, and can open the device and refuse the fuse] .

On Tab A devices, there was a way found for rooting without tripping knox (harware set)...that was Kingo i think. However, i had already rooted my device by then, and Knox counter was set. I am not aware what the policy is in my country, but i believe my warranty is now void.

However, i am not too down about it, as if there are any firmware issues, i think i can fix them myself (not to jinx it). If i have hardware issues....well, i guess i will have to pay up :)
