Is there anyone out there who can confirm the root Ashyx created? I'm hesitating to try before I brick my new tablet :crying:

so I should go into Download mode with the tablet and use Odin to flash ONLY the file you've posted?

What if it fails?

Why are you building some kind of recovery for Calaiou?
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Why not just read the thread, it's already been confirmed working several times.

It won't brick your tablet if you have the right model.

If it fails, which is unlikely, you can easily recover by flashing the stock recovery I have posted.

I used your t550 .tar on my t555 with odin3_v3.10.6 and my tablet is not stuck in boot loop :crying:

It shows a red android logo, with text like mounting, restoring, rooting, cleaning up, restart in 10 seconds, and never stops :crying: it does it over and over and over.

And i cant even turn off the device since battery is non-removable.

Did i brick my tablet?
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
No youre fine. Its only a soft brick. To reboot just press POWER + VOL DOWN and hold until it restarts. If you cant boot just download your firmware for your region and flash with odin.

Extract your recovery for it and i will build root specifically for your device. Can i ask is your tablet carrier branded and for which region?

http://samsung-updates.com/device/?id=SM-T555
[Galaxy Tab S Q&A, Help & Troubleshooting] isakkeyten:
i cant restart it as its stuck in the boot loop and the boot loop is too short, like 2-3 seconds, so holding the power+vol down button does nothing. Do I have any other option other than waiting for the battery to deplete?

I don't think my tablet is carrier branded since i dont see any branding messages or boot logos. I dont know much about which region is it for since it was a gift from a friend who works at t-mobile, but if it was meant for my own region then it would be Europian region (Macedonia)

so basically this is what i want to know "Do I have any other option other than waiting for the battery to deplete?" and also how to extract recovery afterwards
[Galaxy Tab S Q&A, Help & Troubleshooting] DUHAsianSKILLZ:
Force reboot by holding power+home button+volume up and down buttons until the screen goes black, then press Power+ home button+ volume down

I should've known this sooner!

ok so phone now boots as expected

no root but i wasn't expecting it to work after that XD

how to i pull recovery.img ?

via adb pull? is there a comprehensive tutorial that shows this somewhere?

i have some experience with adb but after this boot loop im scared to **** smth up
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
It doesn't matter whether it's boot looping or not. As long as you hold POWER + VOL DOWN for long enough it will reset.

This is the combination for a hard reset.
[Galaxy Tab S Q&A, Help & Troubleshooting] DUHAsianSKILLZ:
If you have the firmware downloaded, just right click on the tar.md5 and open with winrar or 7zip. Then drag the recovery IMG to your desktop and upload it.
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Can you get a video of what happens, it would make it easier to debug?

Did it say failure to mount system and cache when mounting.

It won't run the supersu script if the mount fails.
[Galaxy Tab S Q&A, Help & Troubleshooting] isakkeyten:
I already fixed the boot loop by pressing and golding power+vol up + vol down + home and then restarting and booting normally

should i fabricate the problem again to record?

also how do i get my stock recovery.img to send it to you?

I didnt download any firmware i was kinda hoping the battery would deplete and id be able to boot normally, thankfully u told me how to stop it

i cant find my firmware if i search T555XXU0AOC3 on any firmware website

Yes I just need the recovery image. You will also have the latest firmware to flash for your device in odin as a bonus.

Also you didn't answer my question about the failure, did it say mounting failed when you saw the red Android?
[Galaxy Tab S Q&A, Help & Troubleshooting] isakkeyten:
no as i remember - it said, and im quoting myself "mounting, restoring, rooting, cleaning up, restart in 10 seconds" but it never was 10 seconds - it was restarting immediately.

it was hard to read what did it really say as the whole script log lasted like 2 seconds and then reboot, 2 seconds of moving text log then reboot, over and over

i will download the image you provided me asap tomorrow and attach you the recovery.img

Hi ashyx, I assume the kernel path is /dev/block/bootdevice/by-name/boot

Correct for the Tab A? Or would it be something else? Based on calaiou picture of cfautoroot I think its that. Just wanted to know do I can deodex the ROM so some peeps can use xposed

BTW someone asked for an custom recovery in the Tab 4 subforum and someone named moonbutt built philz cwm for most if not all of the tab 4 variants. Perhaps you can ask him for help regarding the mounting issues.
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
Yes that is the correct path.

I will check out the other thread later, but I think I have an idea what it is, but not sure how to solve it at the mo.

I know the mount paths are correct, so I assume it's a security issue not allowing the partitions to be mounted. I've had the same issue when porting cfauto root.

These new 64bit recoveries seem to need a signature or key.

It gave me a hint when tgalal mentioned about signing the image for his root method.

I've looked into it and there is a dmverity key that can be used, but there's not much info about how to build it or whether it's required.

Have you got the link to this other thread?

Thanks for that but that is the kernel log for a normal boot.

What I need is for you to install and attempt to boot to twrp (which won't boot) then restart the tablet with POWER +VOL DOWN.

Then once the tablet has booted run the command I gave you in the android terminal.

This should then save the recovery kernel log to the sd card.

The only way would be through adb, but that means booting to a working environment. I don't think adb works at the moment with the cwm recovery I posted.

You could try it and see if you can get adb to recognise your device, but I doubt it seeing as no partitions get mounted yet.

The only other option is to pull the kernel source code from Samsung and see if I can enable the ram console in the kernel which is responsible for outputting to that log.

Its almost impossible to debug something without having logs or owning the device yourself. :confused:

Damn you Samsung for not enabling this. :mad:

You have to flash it back with Flashfire, obviously the tablet has to boot normally to do that.

If it doesnt boot then you have to flash the stock recovery i posted with odin.
