[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] UberSprode:
I managed to root the phone (on 4.2.2 iirc), then upgrade it to 5.0 keeping root.

However the phone has issues playing back streaming video from any/all sources (YouTube app, web browser, etc).

The video will play fine for a few seconds, then the image will freeze while the audio continues.

Local video playback with VLC works when full hardware acceleration is turned on.

What little I was able to find about this issue has led me to think it might be because I'm on an older baseband version than my build number.

My baseband is N900AUCUCN2 and my build number is LRX21V.N900AUCUEOC2.

So my question is, is the mismatch a probable cause for the playback issue?

And if so, is there a way to upgrade the baseband, or to start over and upgrade it while going from 4.2.2 to 5.0?
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] audit13:
I doubt the baseband would affect streaming but the bootloader might. Is the phone running a lp bootloader?
[Android General] RASTAVIPER:
Great job mate!

It seems very analytical and very useful for people who need a step by step guide.

Unfortunately it requires a full wipe of user data, so for now I am not willing to try this guide.
[Android General] brainvision:
Well, I feel you, unlocking is always annoying but there are apps which let you backup everything.

I couldn't live without root + Link2SD into the cube!

Thanks for the nice words ?

Hi brainvison,

it`s a nice, correct and clear tutorial, many thanks.

Only one question:)

Fortunately I have an unlocked bootloader, then I`ll do it from step 10, but I have a same kernel and build version (3.14.37/x86_64-L1-R517 and V1.0) but the date of this version is different (20160913).

What do you suggest, try it? Or could you help me to create a new version of the boot.img, please?

Nice regards

Peter

​
[Android General] brainvision:
both kernel and build dates are different, aren't them?

I'll try to write the missing section as soon as possible, don't worry..

In the meantime could you please check a few things that could help to understand a few things?

If your bootloader is unlocked you should have no issue doing that; assuming you already have adb working, open a terminal and execute this commands (just "read" commands, no mods here)

adb shell
uname -a
cat default.prop

If errors try to execute adb root (this does NOT root, it just use adb as root user, it should work with the unlocked bootloader) before adb shell and if possible please report me the output from unameand cat;)

EDIT: also my advice is to backup your system partitions so to able to go back to stock if needed; at least partitions

android_boot
android_bootloader
android_bootloader2
android_recovery
android_system

To do that you could check Laura's thread from techtablets or use

dd if=/dev/by-name/your_partition of=/sdcard/your-partition.img

the if= option is where you choose the partition to backup while the of= one is the resulting file that will be created (an image .img file)

If you agree you could also upload those somewhere on the cloud so we could use them, too, it would be interesting to see what changes.. Naturally the partition I suggested do not contain any personal file, no worry about that (your data is on the android_userdata - or _data, don't remember the name here).

EDIT2: you'll need a Linux machine to mod your boot.img partition, do you have one?
[Android General] rpeter:
yes, I have, a debian.

One question, if we have any problem with the upload the modified bootloader, how can i restore the old one (how can I upload (which method, adb, fastboot, or the phone flash?) an original bootloader, if we have a problem with the modded bootloader)

Have you link(s) with the full original windows and andoid image of the i15-tcl? I found to i15-t, i15-td, but not for this version...

Nice regards

Peter
[Android General] boberq:
i have the same software version as rpeter. When i first boot in fastboot my bootloader was unlocked and secure boot was disabled. Itried flash twrp and it was succesful. Next i downloaded superSu zip from official website and i flashed it. After reboot i stuck at bootlogo. Can you share me a system image to restore?
[Android General] rpeter:
The mmcblk0p9 partition is the system? I will share it as soon as possible.
[Android General] boberq:
07 is system. 09 is data partition.

[Android General] brainvision:
[MENTION=1230645]rpeter[/MENTION] I'll read your long reply asap, now just want to tell you that to check partition in a human readable way you should use

ls -las /dev/block/by-name/*

the partition I would like you to share are

android_boot
android_bootloader
android_bootloader2
android_system
android_recovery

when using dd of course as I told you can directly point to that name convention (which are nothing but symbolic link) so

dd if=/dev/block/by-name/android_boot of=/sdcard/android_boot.img

this is for the boot partition, the other the same..

also please before uploading to cloud check the MD5 so we could verify it before installing ;)

are you sure you wrote uname -a the right way? It's weird you don't have it...

About restoration, you could use fastboot in future, I tried it by myself.. the most important are

fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img

I don't think we'll ever need the two bootloader restoration, it's just to go extremely safe but I still don't find a reason to flash them.. But backup anyway! :D

EDIT: please note the .img extension for the of= part of the dd command!

[MENTION=3951364]boberq[/MENTION] sorry for your issue but I have to say that it was obvious: it's not plenty of guides and how-to about this tablet but the few available are also easy to find, and they all clearly state that you need to modify the boot image before rooting, otherwise as you know now, bootloop!

so, if you guys need to immediately root you can send me the boot.img file and I do it for you, otherwise you can wait and do it by yourself - I'm going to write the how-to right now, it should be ready for tomorrow, I guess..

EDIT and yes, we don't have any full restoation image like for other variants, I asked them on Twitter https://twitter.com/CubeHeping (it seems this is their official account that I found via www.51cube.com) - please do the same, maybe they will listen to us :(
[Android General] boberq:
I flashed i15 td rom and it works without auto rotation. If rpeter share images i want flashthe stock.

---------- Post added at 12:52 PM ---------- Previous post was at 12:44 PM ----------

I flashed a i15td rom and everything is fine without auto rotate. Rpeter please share boot and system images, they help me to restore the stock rom.

Ps After first boot if i want enter to recovery , it show red triangle with green android. There was any recovery.
[Android General] brainvision:
stock recovery is not a real recovery there.. Red triangle is the right thing.. BUT if you flashed the custom TWRP with

fastboot flash recovery recovery.img

you should have noticed that the process failed.. I don't remember the exact output but you should have seen FAILED instead of SUCCESS. If flash succeed you also need stock recovery, I guess, otherwise it should still bootloop after system restore..
[Android General] RASTAVIPER:
[MENTION=4396658]brainvision[/MENTION]

Has anything changed about rooting?

I remember that the process was involving resetting in order to unlock bootloader, etc
[Android General] brainvision:
nope, and it never will in that direction.. :(

you should definitively make a backup, the more you'll wait the worst it'll be! ;)
[Android General] boberq:
I flashed twrp and from it i want flash supersu and i get bootloop. After this i flashed i15td rom andeverything works fine. So can i flash boot,recovery and system image and get stock without root? Or should i flash it using intel flash tool?
[Android General] brainvision:
you can flash them with fastboot indeed and then root again, I finished writing my how-to, I'm formatting it and update the first post in an hour max..

Never looked at Intel Flash Tool, I don't know if it permits the flash of a single partition or if you need a full image provided by OEM, can't help with that..
[Android General] boberq:
So i'm waiting for original images from rpeter and i'm goind to flash it. I have a twrp backup with original 20160913 firmware but after bootloop. I can sare it but i think it isnt usefull.

PS

Brainvision , can you share me your original partition images for i15TCL from May? I think it will repair my autorotation.
[Android General] brainvision:
I do NOT recommend you to flash that because you will completely mess things up, having boot, recovery and kernel with a build date and system with a different one! You went to fast on rooting your device without reading stuff, now I suggest you to wait for [MENTION=1230645]rpeter[/MENTION] images - but anyway here it is system.img https://mega.nz/#!YBdw1bIT!GibOWLBNyXAhwEiEdXIV3JKKdMM9gXzLIYvppKn0Bgs

EDIT: guys I updated OP with the missing sectioon, please click thanks if you find it useful.. ;)

[MENTION=1230645]rpeter[/MENTION] before rooting remember to backup partition with dd, then upload when you can but backup before rooting! :D

if you have suggestion for the guide or you think something is not so clear please tell me that I'll try to improve..
[Android General] rpeter:

[Android General] brainvision:
great work mate!

Thanks a lot. As you may have read I updated the OP with the new section, hope you'll find useful and clear enough, if not don't hesitate to ask, it will be a pleasure to help and to improve the how-to ;)
[Android General] rpeter:
brainvision:

Thanks for the nice step-by-step howtos.

I did it everything, but i have a good and a bad news:

the twrp recovery working correctly, all steps finished without any problem, but i havn't root access in the android after the steps:(

Have you any idea, what can I missed?

EDIT: the modded boot file and the md5 placed to the web.
[Android General] brainvision:
Did you flashed SuperSU?

Inviato dal mio i15-TCL utilizzando Tapatalk
[Android General] rpeter:
Yes, first time with adb sideload (before this steps, the twrp need a i15t driver to reach adb)

after the flash, the android rebooted correctly, but no superSU and root access.

second time: placed to the sdcard and flashed directly with twrp.

the situation is the same:(

the version, which i tried:

SuperSU-v2.78-201609011115.zip
[Android General] brainvision:
Yea for sideload we need to edit the udev Linux files as I explained in the first section. Unfortunately the recovery is for i15-t so maybe the rule should be replicated for it (I would like to reach vampire to ask how he created the TWRP so to prepare one for us specifically)

Well it's really weird, I did that tons of times and it always worked!

So, flashing SuperSU gave no errors but you don't have SuperSU among your apps, do you?

Try to

adb shell

su

cd /system/app

And see if you have the SuperSU folder with SuperSU apk inside..

If you don't try to mount system partition from Mount section from TWRP before flashing SuperSU package (the version you used is the same I did too)

Many-many thanks for you!
[Android General] brainvision:
Mmmmm.. It's weird BTW because I always flashed SuperSU without mounting system.. But it's also true that this tablet has a system mounting point very unusual: android_system.

I'll update the how to as soon as I go back to my PC.

If you find the how to useful please use the thanks button, it's always a nice thing

Last but not least could you please try now

uname -a

From TWRP / Advanced / Terminal?

I'm curious to see if you have a i15-T output like me(it should be related to the recovery I think, builder with i15-T kernel and boot image)

Has anybody managed to install xposed?

Thanks for the guide!
[Android General] brainvision:
Hi there, thanks for your appreciation!

About Xposed, unfortunately there's no way to flash it!

The issue seems to be related to the x86_64 CPU; I read that rovo was porting Xposed for this arch time ago but then it stopped, mostly because he did not have a way to test (no device) and even if we offer to test anything from him, he never reply..

This is one of the biggest cons of this tablet for me.. I manage to make some basic mods to SystemUI like changing that horrible Clear All from Recents, removed two useless tiles and reordered them.

But I want to add new tiles and no one seems to know ho to do that, it's plenty of guides and how to for JB and KK but no Lollipop! I guess this is also due to the fact that with Xposed you can do everything, no need to mod ROMs by yourself, so no more real ROM modding.. ?

EDIT: hey [MENTION=1230645]rpeter[/MENTION] could you please make a dump of the BIOS too? a guy from 4pda linked me this tool, could you please try and share it? I'll attach the tool to this post, thanks ;)

[Android General] jonascorto:
Increase internal storage:?

Does anyone have any information on this? 8gb is extremely little, the games nowadays are giants. Anyone know if there is any way to increase internal memory? Pick up some of the windows storage.
[Android General] brainvision:
Sure.. I have 20GB for Android and 32 for windows.

The downside is that you need to remove everything on the tablet except the Bios and then reinstall both android both windows using the official firmware. You could also use all the space for Android if you wish..

If you need more just tell and I'll write something about it

Alternatively you could use a 32 GB SD Card and format it with two partitions: the first partition FAT32 so that you could use it on Android and Windows and second one ext4; then using Link2SD or Apps2SD link games and app data and obb to the etx4 partition.

Depending on the size of the partition you'll be able to install much more big games. The downside is not noticeable in terms of games performances but it could be on apps; also battery could last less..

I have Link2SD Pro (bought it back in time of Gingerbread) and tried Apps2SD free: they both works good

Inviato dal mio P80h(D4C5) utilizzando Tapatalk
[Android General] jonascorto:
I'm using link2sd, I put a primary fat32 and a primary ext4 and it turns out it's never right, I had to go through the 2 partitions in primary fat32.

In other cell phones I use ext4 and it works normally.

I would like to know how you increased the android space. It was by flashtools?

If you can tell me more about it, I'm grateful.

---------- Post added at 08:17 PM ---------- Previous post was at 08:12 PM ----------

Sorry for the double reply, have you ever been able to move the app to internal memory? With link2sd I just get the data not the app.
[Android General] brainvision:
Try this with Links2SD: flash latest SuperSu and open it, go to Settings: enable the option Enable root durting boot and disable the following one named Name space etc etc. Root during boot enabled, the other one disabled..

That's what I usually do. But I'm using my own modified ROM with init.d, so not sure but it should work.

BTW I have to admit that the SD Card on iWork 10 often gives problems, it's not only on my device but it's a common issue, so I decided to increase data partition..

If you want to also link to sd apk, dex files, lib you should try Apps2SD.

As said, if you want to resize the partitions YOU WILL NEED TO WIPE EVERYTHING on your device, both Android both Windows. And then reinstall! What tablet variant do you own? It's a TCL one?
[Android General] jonascorto:
Is new with typo c. TCL

I do not mind deleting everything, I just really want to increase the internal memory of the android.

I'm having a problem already have a time.

The microsd recognizes in android and windows not, already formatted and did not solve. I'm afraid it's a physical problem in the slot, I do not know. No microsd recognize on windows and almost none on android.

My 64gb only reconnected on the android after I reinstalled.

Could you teach me how to increase storage?

I already have the intel phone flash the windows 10 and android files and all drivers installed.
[Android General] brainvision:
sure I could! I asked you what version you had because I want to link you the files you'll need so to restore Android to very latest firmware available and Windows to only one available..

now it's 23:10 in Italy, I'll write the how-to tomorrow and I'll post as soon as finished, ok?

see you soon :good:

P.S. Flash Tool is not needed, much easier to use adb and fastboot, so if you want to accelerate things you could install adb and fastboot, make your PC see the device ;)
[Android General] jonascorto:
i15-TCL

I forgot to mention, I already have adb fastboot installed.

I'm grateful for the help, I'm in Brazil and it's still 7pm here.

Thank you and good night.
[Android General] jonascorto:
Let me take the post and ask you something, is it the same with you? My cube will never fill the micro sd in applications.
[Android General] brainvision:
sorry, dono't understand what this photo is about..

But the Android firmware by cube does NOT include any integrated feature to move and install apps or games to external storage, only internage storae (emulated sdcard that is a partition of the eMMC, so still internal storage). To achieve that you need to use Links2SD or Apps"SD, as we previously said..
[Android General] jonascorto:
About the photos. The popcorn time application can not see the microsd to use as a cache.

The other application is Happychick, can not see the microsd for me to save the games.

As if it did not exist.

I already use link2sd and everything is ok.

I just wanted to ask questions about these 2 pictures if this was normal ..

I had a k10000 oukitel that happened the same thing .. the apps did not see the microsd.
[Android General] brainvision:
Well I guess it could be related to the apps; as you may know from KitKat Android requires a special permission to write into external SD card.. Maybe using a file explorer or some other apps you sometimes see this permission request

if an app is not updated with that request it will not work and there's nothing you can do except some fix that I never tried and so i don't know if they work. One fix could be with an Xposed module but Xposed does not work for this tablet, so maybe:

- https://play.google.com/store/apps/details?id=nextapp.sdfix

- https://play.google.com/store/apps/details?id=ch.upper_cliff.sdfixtool

But still 2 things: first, I repeat, don't know if they works; second and most important, if the app has been developed to write those data on internal folders and don't let you choose it, I fear you can't do anything at all, sorry!

But I don't understand: if you are using Link2SD why don't you link cache and data folders of those two apps to the sd with it?

P.S.: while you are around, please download the official Android/BIOS/Windows firmware (it's the i15-TC one, not TCL but you'll only use Windows from here - it's the same identical stuff except that in Settings Info of Windows you'll se i15-TC instead of TCL; if you prefer you could also use a custom Windows installation downloaded from Microsoft, but I think you will lose your legal product key that way): https://drive.google.com/file/d/0B55gm49vxGYHWWpGaEFOMXB4dFE/edit
