I want to make absolutely certain I don't screw up this tab i just bought today to go with my galaxy S5 as a twin brother. I'm quite used to 5.0 on my S5 and the Tab 3 is running 4.4.2 and is bone stock. Sprint version of the SM-T217s. There's no caveats or ifs to this Tab 3 on this FW correct? I've came close to losing a Kindle thanks to 1st gen VS 2nd gen software and want to make sure I'm good to go with the Tab I have on this FW. After being here 8 years I know to be extra careful.

Thanks for the answer in advance.
[Galaxy Tab 10.1 Android Development] Prowler665:
This ROM is for the GT-P750x/751x. If you manage to get it flashed to the Tab 3 at all you will most likely brick it!

Sorry mate, but you're in the wrong forum :D Take a look here.

What version of gapps are you using? The latest version (3-14-15 and 3-17-15 in the first post) are working for me. Don't use the 20141109 gapps on the 5.1.0 ROM.

I noticed that there have been fewer downloads of gapps for 5.1.0 ROM than downloads of the ROM itself.

I have seen reports that Google Play Services is holding a wakelock and completely preventing sleep.

Here is a newer version of gapps. Google Play Service is version 7.0.97. I am not getting any wakelock issues with it.

[Galaxy Tab 10.1 Android Development] yitzi:
I've said it before but THANKS so much for a great build, my Tab never ran so fast! I used the 3-17-15 gapps, nothing but troubles for me, I went back cleared the cache and davlik again, then wiped data, cached, and davlik still no joy. Then did a full wipe and re-installed, still some problems but a litter better. Finally did a full wipe, repair on the partitions, then re-install with 3-17-15 still issues. At last did a full wipe, and went back to the 11/2014 gapps and it worked!!! Go figure?

Anyway, I'm a very happy camper now. Thanks Again
[Galaxy Tab 10.1 Android Development] Prowler665:
Sorry to see you having a hard time on the installation mate. But why didn't you simply follow the problem reporting steps in post #2? The first thing you should do if something isn't working as expectected is get a log.

This serves two major puroses:

It might shed a light on what is going wrong and what is needed to fix it instead of just groping in the dark.

By sharing the logs and maybe the conclusion what might be the cure you're actively contributing to this project, giving back something to the comunity and maybe help others. ...given it actually is a general problem ;)

Edit:

Just a word on the problem you describe and your solution, since it seems quite common.

p75xx-gapps-L-3-14-15.zip and p75xx-gapps-L-3-17-15.zip are 'minimal' GApps stripped down to let you run the play-store and thats it. Some of the Goggle-apps, like Google+ for instance, need additional libs not provided by these packs so they might not run with the full features or not at all. Thats why installing the (full) gapps-lp-20141109-p75xx did help. Inbetween android 5.0 and 5.1 some of the code-base of android changed a lot thou, hence using the 5.0 GApps is not recomended.

About the filesystem operations you described:

First of all a 'clean' install was advised for the installation of the 5.1 ROM, meaning a full wipe prior to installation.

The difference between wiping data, cache and davik and a full wipe is that prior to installing the ROM some backup-scripts are executed, backing up and restoring, among other things, the GApps installed before formating system and extracting the ROM.

Since on the cache and system partitions a new filesystem is created upon wiping, it only makes sense to run a 'repair filesystem' operation (fsck) on data. While this won't hurt I doubt it had anything to do with your problem.

Is it dirty flashable over previous LMY47D build (from 1303), or too many changes that it requires a clean installation?

[EDIT] dirty flashed ROM only over previous build- everything looks normal to me.

Root access p4wifi?

Excellent job on this! This is by far my favorite rom for this device. One thing i cant figure out though...Anyone else not able to get root access? I have been trying to figure it out for the past 12 hours or so.
[Galaxy Tab 10.1 Android Development] Gil81:
First..wiping cache and dalvik will not optimize apps..ur device might say that it is optimizing apps,but really what it is doing is just loading and building back cache.

As for what to install..the ticked ones are the apps not on ur device, as u have figured out. You just need to read the names and see if there are any you want back...but No system apps. They will not work from ICS to lollipop..or even from two ROMs on the same version that are built from such different base branches( example: aosp to touchwiz, touchwiz to cm, and so on )

Just remember that if you install apps and data, the apps might not run. This is because the difference between the ROMs. But the apps alone should be OK..just have to try and see.

And it will not make duplicate data..the app data is not there..just the folders from apps..if they created one. Even if it was there,it would over write it.

Although since you are coming from ICS to lollipop, and the system device tree locations are setup different. If I was you I would see if I could pull the important data off the device ( pictures, files, music, things that can't be replaced ) and put them on a PC. You might be able to pull them from the nand you made. Then after the data is safe, I would wipe my tab completely and start with a fresh slate. This way when you load apps its in the correct directories with out the device needing to move what it can. You can do this in twrp by just wiping sdcard. Then reboot. None of this is necessary though, I just like a clean organized file system..lol.

If you have anymore questions not about this ROM...please use this Link. It is to my Q&A section thread. This way we can keep this thread clean and on topic..Thanks

How did you get wifi, sound, screenshot, and camera working? I just had some spare time this Friday night and all yesterday. For reasons unknown, I cannot get the wifi module to load and I think it refuses to load the ics audio blob. For screenshot I attempted to merge the relevant flags needed to make it work in kitkat but it caused a sigbus error. I ended up taking a quick and dirty approach just killing screenshot altogether to prevent it from crashing every 2 minutes.
[Galaxy Tab 10.1 Android Development] CraigWiggins:
Put the 11/14 update on. Not much difference. I have noticed Facebook gets laggy and FC's a lot. Not that big a thing, though it does kill performance overall when it happens. Maps v9 crashes, always. But I had the same issue on KK, so I expect this is a Maps v9 problem and not this rom. Chrome gets a little laggy on some sites, but this is likely memory related, yes? **Apparently, the Maps issue is known- v9 does not work with Tegra2 processors. Hopefully this will change, else it is an app rollback.**

I tried some old tricks like diabling HW overlays, force GPU rendering, and limiting background processes to 4, then 2. I don't see a way to overclock.

Youtube and Netflix both perform well. As mentioned previously, bluetooth audio does not.

Keeping it as my daily driver.

[Galaxy Tab 10.1 Android Development] decatf:
If you're having an issue please send me a logcat and kernel log. I don't have bluetooth accessories or other gadgets to test with so the only way I can know what is going wrong is if you send me the system logs. How to do that is described below.

Root the device by installing ChainFires SuperSU.

Install SysLog.

Reproduce the problem.

Open Syslog app and save the Kernel Log and Main Log.

Send me the log files stored in /sdcard/Syslog.

You can zip the two log files and attach them in the forum reply. Also describe exactly what happens before/during/after the issue.

It hasn't been enabled yet. There is a new config flag for Lollipop which I hadn't set. Multi-user will be enabled on the next build.

Hi, i just came axross this thread today and flashed this aosp over a custom ICS rom which was installed a few months ago on my P7500 Tab. I have installed the one which was released yesterday ie.(20.03.2015). Apart a few bugs, the one which is really annoying is the charge rate. My charger isn't heating up like it used to and the rate is very low (7hrs eta from 0-100%) which wasn't the case on the previous ROM. In battery settings i see the source is of USB instead of AC adapter. I atmost think this is a kernel issue. Are there any alternative kernels i can flash? I searched at various forums only to find kernels of android v4.4 and lower. Is there a fix for this, i like this ROM and wouldn't like to revert back just for this issue
[Galaxy Tab 10.1 Android Development] michedenhaag:
use another usb-cable. this rom is perfect and charges like a charm :)
[Galaxy Tab 10.1 Android Development] decatf:
The USB charging mode has not changed since the original patches from August 2012.

https://github.com/Decatf/android_k...sp-lollipop-stable/drivers/power/p4_battery.c

USB 1.x and 2.0 ports provide 500mA and USB 3.0 provide 900mA maximum. (source: Wikipedia). It might charge faster on USB 3.0 ports.

This hack always seemed weird to me. The USB charging patch forces the charging mode into high current mode (2A) rather than low current (500mA) mode. But you cannot change how much power a USB port provides. So why run the charger at a mode when the USB port cannot provide that much power. Seems a little strange. Though at the time of those patches USB 3.0 was not very common.

Regarding p75xx-ICS_AudioHAL-AOSP_5.1.0-20150311

[Galaxy Tab 10.1 Android Development] ajaylion2:
Well, I'm using the same cable that i did on the previous ROM. I use a 2amp charger (yes, a custom one which i tested, I get the full output on my other phone)

I tested using various chargers and cables and I'm very much sure that my chargers and cables are putting it fully through. My other phone charges at full 2000mah(tested using galaxy charging current app) with the same charger and its still a usb2.0

Question1: What does an fsck accomplish with respect to a full wipe? Just checking the File System only increases your comfort level, doesn't it?

Question2: Another I just noticed (kinda late, I know) for [MENTION=4404851]decatf[/MENTION]: is automatic DST activated on TWRP? I am running the latest and greatest and it currently runs one hour late. Not a problem, just the naming of nandroid backups has a timestamp in its name. The tablet itself displays the correct time, so methinks it is only TWRP that does not know automatic DST rules... Again, not a problem, just a quirk I noticed just now... The option for "Do you use DST?" is checked and the timezone is correct, so it seems the odd North American switching dates are not enabled...
[Galaxy Tab 10.1 Android Development] Prowler665:
Well, kinda... :D

fsck (for file system consistency check) is a tool for checking the consistency of a file system with the option to repair it. Since for the cache and system partitions a new filesytem is created on every wipe it is pretty useless here. For the data partition on the other hand it might make sense since on a wipe the data is erased using the rm command - so the filesystem might get tainted over time as the result of a crash or forced reboot. The only files that might benefit from a fsck would be the ones in your internal storage thou, since these files reside in the data partition too, whereas all other files are being created new after a wipe anyway.

So there might be some scenarios that indicate a filesystem-check, but with respect to a full wipe using fsck mostly has a placebo effect ;)

Regards
[Galaxy Tab 10.1 Android Development] decatf:
Yes.

I don't think TWRP has automatic DST.
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Tainting of the file-system is dependent on the type of fs used, we are oh so lucky that FAT (or one of its derivatives) is not used here. But as long as the filesystem is not broken an "fsck" will do read-only actions, no ironing out of anything of that kind. At least that is how it was told to me (I have been an U**X guy for the last few decennia - I'm long in the tooth now) and indeed no impact. That was the reason I posed the question.

---------- Post added at 07:12 PM ---------- Previous post was at 07:09 PM ----------

No, guess not, but does TWRP source-code have anything to determine DST or not? As the "Do you use DST" question is present I assume some form of DST coding to be present. I will browse through the TWRP source to see if I can find anything (automatic) DST related...
[Galaxy Tab 10.1 Android Development] Prowler665:
I was refering to 'tainted ' only as a general term ;)

As long as there are no errors fsck will change absolutely nothing on a ext2/3/4 filesystem :D

I never was into U**X that much, but I remember building a Linux-kernel for the 80486 about ~20 years ago :)

Spring-chicken :o (I predate U**X [even Minix/Usenix] by quite some time, I should have been extinct, coming from main-frames as early as the early/mid-seventies)

But I did notice the 20150320 LP 5.1 release to be much smoother in the full-screen scrolling inside games, compared to the 5.0.x releases.

We cannot say it enough: this is a great product, and it extends the life of the p4[wifi] dramatically, making it into a very decent product!

I had the same. 2x (also with an older rom). I formatted all partions incl. Internal storage and installed the rom again. Now all is normal again.
[Galaxy Tab 10.1 Android Development] GT_Hawk:
So new to all this. I have obin and used it to load a older twin for this P7510 and that's fine, device was rooted. But see a twrp available here and else ware but are zip files instead of tar. The odin dose not see them and will not use them (even when manually entering the info). Seeing in the thread older twin don't always work so how dose one load the one form this thread ?
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Very good and clear guides. I would make the remark on NOT to wipe internal storage stand out a bit more (colouring and/or fontsize), but for the rest very complete and almost foolproof... But yes, to go from stock to TWRP recovery there is always CWM (with Odin) as a stepping stone to pass. Is there no TWRP md5-file anywhere? Would be handy to do a one-load-fix-all for the impatient...

Cheers
[Galaxy Tab 10.1 Android Development] Prowler665:
So CAPITAL LETTERS, bold and

underlined

does not stand out enough :confused:

I guess the only thing certain about being foolproof is that there will be a fool to prove you wrong :D

But fun aside, there is a way to convert the Zip's to tar.md5. I don't think it's worth the effort thou, since using pershoot's files is way easier and IMHO a lot more reliable...

This should work with the single image builds up to 2.8.0.0. The experimental builds use the additional extra.img so this won't work out of the box for them. ...and of course you will need the correct version for your tab...

First extract recovery.img from the zip-file since this is all we need.

Next the img-file is encoded in POSIX 1003.1-1988 (ustar) format and the md5-hash is added.

Optionally you can rename the file from .tar to tar.md5...

unzip -j twrp-2.8.0.0.zip recovery/recovery.img
...
tar -H ustar -c recovery.img > recovery.tar
md5sum -t recovery.tar >> recovery.tar
mv recovery.tar recovery.tar.md5

I didn't test it, so this might brick your tab. Use at your own risk!

Have you tried the ICS audio HAL?

http://xdaforums.com/devdb/project/dl/?id=11542

Are you using F2FS? Because that is known to have corruption problems.

Also as a general comment. I've tried an even more recent version of F2FS and the fs corruption happens after just a couple of reboots. fsck.f2fs also still cannot repair all filesystem errors. I think maybe I"ll try some older versions of it instead.
[Galaxy Tab 10.1 Android Development] bert73:
I did not use f2fs. Shortly before crash i deleted some files in android/data folder. I think i meshed up that folder.

Can you send me system logs from your device after using HDMI?

The Lollipop audio HAL that is included in the ROM does not have HDMI support because I don't know enough to backwards engineer it. Having the system logs of the old ICS audio HAL using HDMI would be helpful in understanding how it works.

How to save system logs:

Root the device by installing ChainFires SuperSU.

Install SysLog.

Use the HDMI audio playback.

Stop HDMI audio playback and disconnect the HDMI.

Open Syslog app and save the Kernel Log and Main Log.

Send me the log files stored in /sdcard/Syslog by uploading the files to Dropbox or another similar site. Then PM me a link to the files.
