Even if we could flash with TWRP I'm not so sure that is safe to do. Its a bootloader, one of the more important partitions to not get wrong, lol. I would do it with Odin or Heimdall strictly. But maybe TWRP is capable of doing it? I mean isn't that what the images option is for? bootloaders and recoveries?

Bootloader thread:

Information on failure with Heimdall. I didn't read the thread, just found it and posted it here for you.

Hi, guys.

About the problem with black sreen in recovery mod, the log is that generate with TWRP?

Can someone with a T800 test this build and let me know if it fixes the long load time issue?

twrp_3.0.0-0_sm-t800
[Galaxy Tab S Android Development] Carlosk1966:
Hallo.

I have tested this build on my SM-T800. It takes about 20 sec to boot in recovery.
[Galaxy Tab S Android Development] ashyx:
How is that compared to before?
[Galaxy Tab S Android Development] Carlosk1966:
Well. I do not know excatly, but i think now is 5 to 10 sec quicker.
[Galaxy Tab S Android Development] ol31:
Big trouble here. Cannot reboot.

The only thing I can do is to long click on power vol+ vol- together. Then Samsung logo appears. But if i stop pressing the 3 buttons , no reboot to Android .

I cannot either reboot to recovery...

What do you recommend ?
[Galaxy Tab S Android Development] Tilagoon:
Go to donwload mode, connect your tablet to your PC and with Odin flash the old TWRP that should fix it !
[Galaxy Tab S Android Development] ol31:
I do not know how but finally goes to twrp 3 then to android then flashify twrp 2.8.7.2 . Now it works Perfect . Can reboot quickly to twrp without issue..
[Galaxy Tab S Android Development] ashyx:
Update: rebuild for the T800 - Hopefully fixes slow load time.

TWRP 3.0.0.0

i flashed this version with ODIN.

I reboot in to TWRP.

Black Screen and i´ve to wait a long time and then i´ve to press the power button. in settings i disabled the screen timout without any change.

Switched back to 2.8.7.2
[Galaxy Tab S Android Development] ashyx:
Dont disable the time out, set it to 15 secs. This will refresh the frame buffer then just press home and you should see the twrp lock screen.

You guys must need to update your firmware or something, probably bootloader, as others with the T800 are having no issues.

This is built natively for the T800. Kernel, ramdisk, twrp configuration are all T800.

The exact same build boots just fine on my t805. It wouldn't make sense for it not to on the T800.

If someone can post the recovery.log to pastebin I can at least take a look.

Also does anyone have the same issue with the official version?
[Galaxy Tab S Android Development] shakeelajmal:
recovery not working, after flashing recovery to my T805 blank screen have to force reboot and flash old recovery, almost every one is having problem with new recovery please remove the links till you fix this bug
[Galaxy Tab S Android Development] wmanux:
Hi, I have the same black screen problem.

SM-T800, bootloader T800XXU1BOJ1

I sent the recovery.log here: http://tinyw.in/IJRL

[Galaxy Tab S Android Development] shakeelajmal:
update: flashed latest firmware then flashed latest twrp still same "blank screen" revert back to old and its fine
[Galaxy Tab S Android Development] ashyx:
I have the T805 and it's working just fine.

As it is for many others.

You don't have to force reboot. Just wait 60 secs then press Home or Power.

Why some are having this issue I don't know, but I'm working on it.
[Galaxy Tab S Android Development] ashyx:
Thanks for that.

Is that the log from the official twrp or this version?

What happens with the official twrp for the t800?
[Galaxy Tab S Android Development] wmanux:
it's from the official version

---------- Post added at 10:11 AM ---------- Previous post was at 09:30 AM ----------

I just reflashed your latest build (always black screen on boot)

Here the recovery.log:[/url]

[Galaxy Tab S Android Development] ashyx:
How long does it take for the official version to boot?

New build from scratch with some adjustments to the config. This boots and functions perfectly on my T805. See video below:

Can someone with a T805 also flash this and confirm it works ok?

Hi,

it's the same for me.

Regards
[Galaxy Tab S Android Development] ashyx:
Can you try the build above?
[Galaxy Tab S Android Development] wmanux:
Official takes about 15 seconds and your build about 13.

I installed your latest build and the problem still there.

Here the new log:

http://tinyw.in/4Mqp

Actually, if you know that you have to wait for the screen timeout, this is not a so annoying bug, maybe you can put a note on the first page until the problem is not solved?
[Galaxy Tab S Android Development] ymlik:
same here.

---------- Post added at 12:00 PM ---------- Previous post was at 11:52 AM ----------

For me after flash with odin black screen but I could quite quickly enter the TWRP pressing home . As against the second start in recovery mode , the black screen was very long.
[Galaxy Tab S Android Development] ashyx:
Does the official version have the same behaviour, does it boot to a black screen?

I think I see the problem, Twrp has changed the way it sets the right colour space and this seems to be causing the issue.

You can see below the pixel format is being changed from BGRA_888 to RGBA_888.

I will recompile with the pixel format set to RGBA_888 as this is what TWRP thinks it should be.
[Galaxy Tab S Android Development] ashyx:
Can anyone tell me if the official version boots to a black screen?
[Galaxy Tab S Android Development] wmanux:
black screen with the official for me
[Galaxy Tab S Android Development] ymlik:
for me too.
[Galaxy Tab S Android Development] ashyx:
So it's not just my version?

If the next build has the same issue I may have to file a bug report.
[Galaxy Tab S Android Development] wmanux:
I reported one this morning here https://github.com/TeamWin/Team-Win-Recovery-Project/issues/589

If your colour space fix works you can send them the fix

But thanks anyway!
[Galaxy Tab S Android Development] ashyx:
Thanks, strange how it works for you and the T805, but others are having issues?:confused:

Anyway here's another build. If this one doesn't solve the issue I will pull the T800 update and revert to the previous version with the new v3 theme until BigBiff comes back with a fix.

twrp_3.0.0-0-sm-t800_fix

Just so people know, the issue is just the display. Pressing any button after the screen timeout is activated should fix the issue. Setting time out to 15 secs is a work around.
[Galaxy Tab S Android Development] ymlik:
Sorry [MENTION=4899305]ashyx[/MENTION], It's always the same, thanks for your work.
[Galaxy Tab S Android Development] SkOrPn:
It doesn't really work for me. Like I said it does not keep its settings which proved to annoying, lol. I flashed back to 2.8.7.2 for the time being until teamwin releases a new build for my T700. For reference 2.8.7.2 boots in exactly 7 seconds.

TeamWin released a buggy build IMO.
[Galaxy Tab S Android Development] ashyx:
They changed a lot with this release and bugs were bound to happen.

But no display is a show stopper really.

I looked at reversing some of the commits, but there was far too many.

Unless you really need something that v3 offers then those with the issue may as well stick with the previous version.
[Galaxy Tab S Android Development] ashyx:
Is there any chance I could get the recovery.log for that? I need to see if twrp recognized the flag I used.
[Galaxy Tab S Android Development] SkOrPn:
Agreed yet again. Lol I like your 2.8.7.2 better anyway. I even like the theme better and the ui layout is easier on me. It just feels more polished. Yes 3.0 will need some more work.

What exact new features did they bring with 3.0? I must not have needed them if I didn't find them when using 3.0.
[Galaxy Tab S Android Development] ashyx:
Update 1/3/16:

Have Reverted back to 2.8.7.0 for the time being for the T800 until the display problems are fixed, however I have modified the TWRP v3 theme so it can be merged with v2.8.7.0.

For all intents and purposes 2.8.7.0 looks identical to v3.0.0-0 now. Aside from a slight adjust to the background which I found a little too grey, so have darkened it slightly.

All fixes are as per the first post.

This version is now labelled TWRP 2.8.7-3.

Please someone test and report back.

happy to test this...but do not have a custom recovery installed...can it be flashed through odin...?

ignore that last post...it loads as a .tar file in odin...although for some strange reason i cannot disable auto reboot

ok update recovery flashed through odin no problems...deleted 'install recovery.sh' script...from system/etc,using rom toolbox pro,(es file explorer couldn't seem to show the system folder even with root access granted through 'root explorer' option and 'show hidden files' enabled),....which enabled me to boot directly into recovery with flashify without having to worry about the stock recovery overwriting TWRP...tried making a nandroid and even though i have an 8gb ex sd card it keeps refusing to allow me to create the backup even with only 'boot,system & data' ticked it fails as total size of all data is 7605mb and ex sd card is 7616mb...had to disable 'free space check' in order for the backup to start,it starts then fails again (error=255)

log attached
[Galaxy Tab S Android Development] ashyx:
Have also uploaded a new version of TWRP 3.0.0-0 for the T800 (for those that still want to use it regardless of the display issue).

TWRP 2.8.7-3 works fine on my T-800.

But then, so did 3.0.0.

Haven't had any screen issues so far.
[Galaxy Tab S Android Development] SkOrPn:
1. What install method did you use exactly?

2. What bootloader version are you on exactly?

3. Where did you download the 3.0.0 version from exactly? Official TWRP.me or from OP?

Thanks
[Galaxy Tab S Android Development] Dnorris55:
3. I've used the official TWRP, and a couple of ashyx's builds. All worked OK.

2. BOJ1

1. Download the .tar file, extract the recovery.img from the .tar file in ES FileExplorer Pro, boot into recovery, install image, locate the recovery.img, flash it.
[Galaxy Tab S Android Development] mrsim:
1) odin from stock recovery for 2.8.7-3 load the .zip into AP odin 3.10,(then flashed 3.0.0 with flashify after extracting the .img file it's working ok for me too)

2) build no:BOJ1

3) from post #428 http://xdaforums.com/showpost.php?p=65607390&postcount=428

[MENTION=4899305]ashyx[/MENTION] did notice a difference with 2.8.7-3 it does not have the 'system image' available in the 'backup' section only 'system' whereas in 3.0.0 the system image' choice is present

Your sizes above are incorrect. 30mb of your sdcard is already in use.

The problem is insufficient space to backup to the external sd card:
[Galaxy Tab S Android Development] mrsim:
these were the sizes after i had formatted the ex s card...after attempting to backup folders were created and so the size became smaller..am waiting on a couple of 32gb cards and a 128gb card so will put one of them in for the backup...will hold back from flashing any roms until then...thanks for your quick responses and a great recovery......:good:
[Galaxy Tab S Android Development] SkOrPn:
[MENTION=4899305]ashyx[/MENTION], I thought these guys needed to be on XXU1BOL1 bootloader for 3.0 to work properly? That's the bootloader I am on although a different device.

EDIT: I guess different regions use different bootloader versions.
[Galaxy Tab S Android Development] ymlik:
Thanks [MENTION=4899305]ashyx[/MENTION] , I flashed TWRP 2.8.7.3 and then I flashed your latest TWRP 3.0.0.0 and it works ,no black screen. :good:

Apparently not, it seems it's not a bootloader issue.

[Galaxy Tab S Android Development] ashyx:
And is timeout now working OK?

Tbh I can't see how disabling timeout can solve the issue as screen timeout doesn't activate until at least 15 secs.

I think maybe it's more likely to be an incompatibility with the previous settings or you didn't in fact have the latest version.

Maybe it's worth deleting the .twrps settings file after first boot.
[Galaxy Tab S Android Development] SkOrPn:
Where is that located at? Maybe that could solve my settings problem

[Galaxy Tab S Android Development] ashyx:
UPDATE 5/3/16:

Have modified the twrp source code and extended factory image partition flashing to include all images except SBOOT.bin (still working on how to flash the bootloader via recovery)

This means BOOT, SYSTEM, RECOVERY, CACHE, HIDDEN, MODEM(RADIO) can all be flashed from the factory firmware. No need for ODIN anymore. As far as I know the Tab S is the only device supporting this at the moment.

(Note: to flash the modem it is necessary to rename MODEM.bin to MODEM.bin.img first)

T700?
[Galaxy Tab S Android Development] LazyT:
Can do what I want: black screen on T800!

- delete .twrps

- flash 2.8.7.0 and disable timeout before flashing 3.0.0.1

When I disable screentimeout in 3.0.0.1 I've to flash twrp via heimdall because no chance to get into recovery or boot to system.

Are the settings different in each version, because 3.0.0.1 starts with defaults after flashing? So how can it be that disable screentimeout in 2.8.7.x should have any effect?

Hi all!

I have a Note 3 neo N7505 rooted and I want to install TWRP recovery in it. I have tried to do it with the app and throw Odin without success (phone bricked). I think the problem is the position of the RECOVERY link inside the directory tree: in my phone is on: /dev/block/platform/dw_mmc.0/by-name/RECOVERY, it points to /dev/block/mmcblk0p10.

The question is: can I install the last TWRP recovery invoking this command without doing any damage?

dd if=/position/of/recovery.img of=/dev/block/platform/dw_mmc.0/by-name/RECOVERY

Thanks.
[Galaxy Tab S Android Development] :
I think you greped the correct thread in the wrong forum.

That beeing said: if your recovery image is matching you device, the answer is yes.
[Galaxy Tab S Android Development] nglpx1:
Thanks for the reply!

I think the correct image is that for Note 3 Neo N7505 LTE (hlltexx) - I have the LTE version (I cannot paste the link).

If I brick another time the phone, can I resurrect it by rooting it again (as I did to recover it before)?
