I tried flashing v3.0.0 via twrp but it won't boot up on my t705. Then next I tried via Odin but it failed. I lost my installed twrp. Now only the download mode is functioning. I flashed back the stock ROM but still fails to install saying cannot open port. Ashyx, how to bring back the tablet to life and installed your latest twrp for t705?
[Galaxy Tab S Android Development] funfun99999:
flash the old TWRP 2.8.7

Sorry might have cocked up there with the wrong kernel image. Try this: twrp_3.0.0_sm-t705

Thanks ashyx. This is twrp is now working on my t705. I have flashed it via Odin. Good!

Can I flash this with Flashfire ?
[Galaxy Tab S Android Development] dapat:
Ashyx, why can't I restore a back up. I know that this is not twrp related. The twrp is fine but I think there is something I must configure so that I can properly restore a back up. Thank u for your work and your undying support.
[Galaxy Tab S Android Development] zigonneux:
it's written in red, mounted read only, so change the permission of the backup file for r-w read and write
[Galaxy Tab S Android Development] dapat:
How should I do that? This is the folder of the back up I want to restore.
[Galaxy Tab S Android Development] zigonneux:
you need a rooted device then a good file explorer that can change files permission. than read this : http://xdaforums.com/galaxy-s2/general/guide-noob-guide-to-set-file-permissions-t1857648

actually TWRP can change the files permissions, it also has a file explorer. Check the options of TWRP
[Galaxy Tab S Android Development] dapat:
Thanks. Actually my device is rooted. And I always us es file in changing permissions. In this case, options to change permissions are not showing in es file app. By the way thanks for the link buddy.

You didn't enable the system partition to be writable.

Recent versions don't automatically mount system writable and you will be asked when you boot into recovery if you want to mount system as read only or you can enable/disable it by unchecking MOUNT SYSTEM PARTITION READ-ONLY under the MOUNT tab.

Thanks, I search a while for a working T805 recovery.

Does your T807 TWRP work on Stock T807T Tmobile lte?
[Galaxy Tab S Android Development] ashyx:

[Galaxy Tab S Android Development] jrbd:
What have I done?

Hi ashyx.

First of all, ty for your continuing work.

This evening I tried flashing twrp on my rooted sm-t805 via odin, as it seemed to me it's the suggested method in this thread (flashfire is also mentioned, but no opinions about flashify). I opened Odin3 v3.07 as administrator.

I used the .tar file I took from the link in #303 post at pag31.

I booted the tab into download mode and connected it to pc with its cable. Drivers are ok, Odin added it in the blink of an eye.

Unchecked all boxes except for F. Reset Time (should I have checked the Auto Reboot, I wonder...), Start and got a green pass message after about 2 mins. Battery more than 60% (probably more than 90%).

BUT! I can't turn off the device...do I have to repeat the process with Auto Reboot? Do I risk the recovery being replaced with stock?

:confused:

Also I find funny how almost all tutorials for flashing recoveries suggest a prior backup...I tried adb and titanium, but they just don't work enough for me...maybe I'm missing something...
[Galaxy Tab S Android Development] shpitz461:
So you're stuck in download mode? just press the same key combination and it should reboot after a few seconds.

Flashing recovery should take a few seconds, you said 2 minutes, that's way too long...
[Galaxy Tab S Android Development] jrbd:
Thank you, I already tried the combinations but alas, I'm stuck.
[Galaxy Tab S Android Development] rs200z:
I supposed the TWRP 3.0 supports F2FS as well?
[Galaxy Tab S Android Development] shpitz461:
You could always flash recovery again and check the reboot box in ODIN, no harm in flashing something twice.
[Galaxy Tab S Android Development] jrbd:
Update: when I came back home today, my sm-t805 wasn't turned on. Luckily plugging it into the wall charger and pressing power booted it without issue. I have all my data and the device is still rooted.

To be true, I didn't try pressing ALL FOUR buttons to power it off, dunno, maybe it'd have worked...

Sorry for posting here, I didn't know there was a Q&A section (I've seen it at top of the page just now).

Now that I don't know whether to trust odin (or my pc, for what I can tell) or not (but I rooted the tab with odin...), but still want to flash twrp, what can I do?

I'd try again from a pc program (heimdall?), for now I know what to expect (waiting for the battery to run out is no big deal)...but if you think apps are good enough...I'm open to any advice.
[Galaxy Tab S Android Development] SkOrPn:
If your referring to stock twrp 3.0.0, no I just checked and do not have the option to change file systems to F2FS. CM12.1 just got official support for F2FS too, probably because of the majorly exciting F2FS update in mid January. Will have to wait for a custom built version of TWRP with F2FS support I think. Or keep using 2.8.7.2. :good:
[Galaxy Tab S Android Development] ashyx:
I already posted an update to v3 for the t705/t805 last week in this thread.

Post #303 and #310
[Galaxy Tab S Android Development] ashyx:
You need to reboot to recovery immediately after flashing.

Hold POWER +VOL DOWN +HOME as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons.
[Galaxy Tab S Android Development] SkOrPn:
I thought he was referring to stock twrp F2FS support though. Since he didn't mention any specific model number or ashyx twrp custom version, thus I answered appropriately for his exact question.

I can't wait to try F2FS out but I truly wonder if there will be a noticeable difference or not. It's a night and day difference on my Nexus 7 using F2FS. But I would like to think this device should be faster to begin with. Lol
[Galaxy Tab S Android Development] ashyx:
I was replying to this statement :
[Galaxy Tab S Android Development] zigonneux:
@ SkOrPn are you sure that it is a lot faster over time ? I've tried it many time, I flash roms and update often. I haven't seen much difference between F2FS and ext4. The thing is that when we flash a new rom and clear the cache, the tablet is faster anyway. I have 2 tablets to test with and I'm not convinced that F2FS is such a great thing. Good but not a life changer . IMHO ! I still use it though, but if it's not there, I won't mind.

-------

forgot to say, version 3.0.0 MIGHT need some fine tuning, I got corrupted backup on 2 tablets. ( couldn't restore older backup) I reverted to 2.8.7.2 and 2.8.7.0 so I can't validate for sure. Anyone else with this problem or just me ?
[Galaxy Tab S Android Development] SkOrPn:
I wouldnt know, as I said I have never tried it on the TAB S. It was and remained a night and day difference on my 2012 Nexus 7 though which is known to have really bad low cost NAND. In fact, without F2FS on my Nexus 7 it would have been retired a year sooner then it did. F2FS allowed me to wait until I could afford a TAB S (which I only paid $200 for), so thank you F2FS :good:

I'm not convinced it will be the same experience on this TAB S though.
[Galaxy Tab S Android Development] ashyx:
Nope. Have been backing up restoring and flashing various things for over a week with no issues at all.
[Galaxy Tab S Android Development] treo4life:
Was this updated for the T700 Ash ?
[Galaxy Tab S Android Development] ashyx:
Not yet. Not sure I will for the T700/800, I think most people are happy with the official version.
[Galaxy Tab S Android Development] SkOrPn:
I'm definitely not happy with the newer official 3.0 version. I much prefer your 2.8.7.2 version myself. I don't see any other way to get F2FS support other then using 2.8.7.2. Besides the theme is nicer looking on your 2.8.7.2 version, lol.

EDIT: HAHAHAHA, I was double checking TWRP 3.0 to see if it had F2FS, and LOL I accidentally wiped the device. Stupid clumsy fingers of mine, hehe :o
[Galaxy Tab S Android Development] treo4life:
Thanks for the response, I would like your version if you ever decide to update it to v3.
[Galaxy Tab S Android Development] SkOrPn:

[Galaxy Tab S Android Development] SkOrPn:
Does anyone know if a TWRP Backup can be restored over the top of a newly formatted F2FS partitions if the backup was running on EXT4 during the backup? Or does one have to install the same rom and setup everything from scratch on top of F2FS? I can't remember...
[Galaxy Tab S Android Development] ashyx:
Yep just restore as normal. It will convert to the current partition type.

[Galaxy Tab S Android Development] SkOrPn:
OK thanks for the info. It didn't work so after several tries I have to assume the T700 version of TWRP with F2FS support either doesn't work, or the CM12.1 ROM does not have it implemented correctly. Tried CM13 also and it too never booted. On my 3rd ROM with F2FS support and praying it boots. If not I will go back to 2.8.7.2 and try from there. :good:

EDIT: OK, the 3rd ROM from Schischu boots just fine with F2FS. So both CM12.1 and CM13 from deadman just sits at the boot animation for nearly an hour before I gave up and tried again. The ROM By [MENTION=2371134]Schischu[/MENTION] booted right away using F2FS. So at least I know TWRP 3.0.0 is OK. Yay!
[Galaxy Tab S Android Development] corb06:

---------- Post added at 12:45 AM ---------- Previous post was at 12:25 AM ----------

In fact it is a nightmare. Impossible to reboot to recovery. Previous worked much better. Can we downgrade ??
[Galaxy Tab S Android Development] SkOrPn:
Previous was 2.8.7.2,so how could you know if previous worked better if you were on 2.6.2 like you claimed?

I'm using twrp 3.0 and I can reboot to recovery all day long hundreds of times without failure. So obviously you did something wrong. Besides 2.6.2 does not support flashing recovery images according to Dees_Troy. You need at least 2.8.4.0 according to the official twrp website. Use Odin and flash the tar file and your troubles might go away. Unless you don't care to do things correctly. Lol
[Galaxy Tab S Android Development] meduza:
Ashyx 2.8.7.2 supports img flashing... .

m.
[Galaxy Tab S Android Development] SkOrPn:
Yeah all versions above 2.8.4 do. One of my favorite features of TWRP. Boot images and Recovery images as far as I know.
[Galaxy Tab S Android Development] rs200z:
Will you be releasing one for the T705 devices as well?
[Galaxy Tab S Android Development] ol31:
sorry for my mistake. Previous one installed on my tablet working perfectly was 2.8.7.2. I flashed to 3.0 from 2.8.7.2.

I flashed img as a recover image and then reboot to recovery. I think it was the easier and a correct way.
[Galaxy Tab S Android Development] meduza:
Absolutely +1 :)

[Galaxy Tab S Android Development] ashyx:
Still no feedback on mtp?
[Galaxy Tab S Android Development] ashyx:
I suggest you do it again as you've messed up somewhere.
[Galaxy Tab S Android Development] ashyx:
I don't think so.

TeamWin will be updating the official version with my device tree for the t700/705, so there's not much point.
[Galaxy Tab S Android Development] ol31:
here is EXACTLY what I did :

- download tar file and extract to internal memory.

- reboot to recovery (TWRP 2.8.7.2)

- flash img image (recovery type)

- reboot to recovery.

reboot to recovery failed : after 30 minutes, screen remains black. After a couple of try I managed to reboot normally my tab. From that I tried to reboot recovery (from menu option as I used to do). Never work even after 30 minutes. Then I reboot to recovery with power vol and home button. It took a while (much longer than 2.8.7.2) but finally was in.

Tonight will try to reflash recovery from recovery. And also will try from fastboot method. I am under linux, therefore no ODIN method possible.

Thanks
[Galaxy Tab S Android Development] SkOrPn:
I wonder if you need to be on the latest bootloader? I would like to think they would have mentioned that requirement so I doubt that's the reason for it not working for you. I would download it again just in case you got a bad image because it works ok here.

Does that mean teamwin will be including both F2FS support and the Bootloader button? I assume that is exactly what that means right?

The build deadman gave me for T700 has one minor problem, it doesn't keep its settings on a reboot. So an official build with your modifications would be most welcome. Thanks again for your work on TWRP.

---------- Post added at 06:49 AM ---------- Previous post was at 06:43 AM ----------

Oh I forgot to ask, exactly what do you need to know about mtp? I can test for you but I'm not sure what your asking for. Give me exact steps to reproduce the problem and I will give it a try and report back.

Other than my need for sleep every day I am available 24/7 365. Lol

---------- Post added at 06:57 AM ---------- Previous post was at 06:49 AM ----------

Actually you have a piece of software called Heimdall that works just like Odin, but claims to be better. Samsung doesn't have fastboot mode. Samsung uses Download Mode.

http://glassechidna.com.au/heimdall/
[Galaxy Tab S Android Development] ol31:
ok thanks.

was thinking first time I installed TWRP through fastboot... Maybe it was with Heimdall (which I know too). will try heimdall then
[Galaxy Tab S Android Development] ristokoo:
T800 here with your TWRP 3.0.0. Tablet shows in Windows 10 as a media device, I can copy files to and from the internal/external sdcard.

Sorry couldn't find what was the problem exactly?

Edit: I noticed an interesting behavior in TWRP reboot. When I had my laptop connected with USB cable, selecting Reboot - Power Off does not power off but reboots to recovery. Without the cable it shuts down the tablet.

Also sometimes after shutting the tablet down with TWRP Reboot - Power Off, pressing the power button reboots to recovery. It seems to happen after having been connected with USB.

Yeah that is working for me also on Windows 10

TWRP 3.0.0.0

Hi, my Device:

Samsung SM T800

Phoenix Rom 2.0

TWRP 2.8.7.2

i flashed the new Version from POST 1

i tried the .img file with flashyfy then inside the TWRP. Al least the .tar with ODIN.

Now my problem: when i try to reboot to recovery i got only a black screen. i´ve to wait 60 sec and when i press the power button i got the lookscreen from inside TWRP.

Is this normal ?

Any hints ?

You may be right regarding the bootloader as the latest build is

using the latest kernel source.

Also MTP has never worked in any previous versions. I've been trying to fix it ever since and have finally managed to get it working.

I just wanted confirmation it was working OK for everyone.

The work around is to change the timeout to 15 secs.

Have you tried it without your sd card in?

Can one of you post the recovery.log file?
[Galaxy Tab S Android Development] SkOrPn:
You know ashyx after a good night's rest finally, I am just now understanding what you were asking for. I guess I needed it spelled out in layman's terms. MTP has always worked for me but I always only used it from the booted ROM. And very rarely at that. 95% of the time I use a usb drive dedicated to this device and in the recovery its 100% of the time. Just force of habit I guess. I even have Wifi Transfer Pro yet I still use a usb flash drive. I think the small internal sdcard got me into that habit as I still have not purchased a micro SD card for this tablet. I keep hoping super fast 128gb micro SD cards will be manufactured someday before I purchase one. Lol

If I remember I will check today to see if my mtp in the recovery works.

If it states for the t805 then usually yes with the odd exception for stock roms. Custom Roms should be fine for any variant.
[Galaxy Tab S Android Development] cdmackay:
thanks much for this, very good. Are you intending to push your changes up to the official TWRP?

oh, just in any case anyone gets stuck, like me... if you test reboot to Download mode, but with nothing to download, you'll find yourself stuck there. Holding down Power does nothing, and nor does Power+VolUp+Home, which surprised me.

But the key combo for getting into Download mode also works to get out of it: Power+VolDown+Home, then Down again when prompted (to reboot).

Gave me a few nervous moments :)
[Galaxy Tab S Android Development] d3xtr0:
Just a tip, if you push first the volDown + Home and after Power, you just need to release the power button after tablet start. Easy peasy :)

@ ashyx is normal that factory reset takes a lot of time on wipe cache stage? Way longer then the official TWRP.
[Galaxy Tab S Android Development] ashyx:
It's normal, wiping cache depends on what cache contains at the time you wipe it. If you wipe again after the first wipe it will be much quicker.
[Galaxy Tab S Android Development] ashyx:
Actually it's just POWER + VOL DOWN. That will reset the device no matter what mode you're in.

[MENTION=4899305]ashyx[/MENTION] would you please consider spinning a build with this fix in too, please?

https://gerrit.omnirom.org/#/c/13095/

I think I just hit it on your build: encypted backups fail at the end.

thanks much indeed...
[Galaxy Tab S Android Development] ashyx:
Can you give me more info as to what actually happens and in what circumstance so I can reproduce it?
[Galaxy Tab S Android Development] cdmackay:
Sure; just try an encrypted backup.

I did Boot, System & Data, with Compression also selected.

The backup starts, but at the end of the partition being backed up, it says Failed.

I tried again without Encryption - all other options the same - and it worked fine.

I did not manually check the log, but the same thing happened to me last week on my Note 3, and the log showed a SEGV. When I posted the log, the author of that fix I referenced above said it was that problem, and the TWRP dev for the Note 3 built a new version with that fix, and it worked fine.

I am assuming it's the same issue here - unless your build already has that fix?

thanks...
[Galaxy Tab S Android Development] ashyx:
Ok i see what you mean.

I notice the changes have been pushed to github so i have rebuilt with the changes, BUT there is still an issue. DATA backups complete just fine with encryption AND compression enabled, however without compression enabled the backup fails with an error at the end.

Having said that I think the error message is erroneous and can be ignored as the backup does actually complete and can be restored no problem.

Try it and report back if you experience the same.
[Galaxy Tab S Android Development] cdmackay:
great, thanks much.

Would you point me at the new build, please?
[Galaxy Tab S Android Development] ashyx:
