[Galaxy Tab 4 General] Pu$$nBooT$:
I just picked up galaxy tab4 ( T235Y ) new off amazon, brand new :p I got it from a reseller but it was shipped from a fulfillment center so it came quick. no warrenty tho...

I opted for 2 year warrenty from amazon just to cover my clumsy ass hehe so I came out ahead if I bought a galaxy tab4 from tmobile directly.. I just returned from a tmobile store and added this to my account, got a micro sim and im up and running... now to root and unbload thid phablet lol

* forgot to add, no lte signal tho just hspa+...
[Galaxy Tab 4 General] TopTongueBarry:
Thank you.

RE: hspa+

Yes, we know, you'll need bands 4, 17, 21, at the very least for LTE enablement in the USA. (Unless you are in NYC or another area where band 5 850 is being used for LTE).

Don't expect to be able to add the US LTE bands until there's a custom ROM available for our devices.
[Galaxy Tab 4 General] Pu$$nBooT$:
I know... works really well on tmobile atm with hspa+... don't see any roms so might as well just wait...
[Galaxy Tab 4 General] g_ding84:
I have two questions.

First, What is the partition layout for the SM-T235 and SM-T235Y?

EX...../dev/block/platform/soc.2/by-name/SYSTEM or something like that......I'd need data / system / kernel(boot) partition names...please

Second, What is the difference between the two devices? Are they like the SM-T230 and SM-T230NU (which are interchangeable - each can run on either firmware)

I'll work on making a custom ROM for the SM-T235(Y) but I need a bit of help. I figured this would be the place to ask.
[Galaxy Tab 4 General] TopTongueBarry:

I love you.

Guys.

I mean, i love you guys!

All the ones that lets me own my own phone (phablet is a wierd word).
[Galaxy Tab 4 General] TopTongueBarry:
It seems that devices with Marvell processors are not favored by many developers, however, g_ding84 is working on an ACHERON ROM for the T235 to add to the collection of Tab 4 ROMS he's already created for the community. God bless him!
[Galaxy Tab 4 General] g_ding84:
Yes I am working on an stock rooted SM-T235(Y) ROM. With SuperSU ( V2.48 ) busybox init.d support and a few other things. Not too flashy, just a nice stable base (like the T231 and T237P ROMs). Going to get the base made up this weekend when I have time.
[Galaxy Tab 4 General] aftnoon2:
Are the recovery problems solved?

I'm not able now to make a nandroid with this thread alpha TWRP. The problem came up after I changed my 32gb card for a 64gb one (which was a new "tour de force" for SD fixing, as SD fix didn't work...).

It recognises Sd card, but as "external-sd", do its job apparently, but the backup is nowhere...

It shows sdcard, sdcard1 and external-sd. The files in the last one are exactly those of the real extSdCard, but apparently it ignores it.

PS: My t235 LTE comes with Exynos... I don't understand the Marvell mention by g_ding84. It's for the t235Y?
[Galaxy Tab 4 General] TopTongueBarry:
Recovery in OP is now a beta. I have not tested a 64GB card so I am unaware of backup issue with them. Will test this weekend.

Marvell is the company who makes the SoC CPU and main board for the device, Exynos is to Marvell like Snapdragon is to Qualcomm, kinda sorta, well, not exactly, but hopefully you get the jist of it. Exynos is proprietary, now owned by Samsung. No royalties to Qualcomm when they use Exynos!
[Galaxy Tab 4 General] aftnoon2:
Many thanks for your response!

OK, I understand the Marvell question.It's sort of Intel "Celeron" and AMD "Athlon"...

For the recovery, I remember that it made a backup on the 32gb sd card, creating the TWRP folder wich is unable to create now.

I don't know if reflashing stock rom (so, stock recovery), and reflashing after the TWRP again, gaining root again, will solve this...:confused:
[Galaxy Tab 4 General] TopTongueBarry:
Have you patched the sd card rw issue on the 64GB SD card? If not, that's probably the solution you need to pursue.
[Galaxy Tab 4 General] aftnoon2:
Surely, I patched it. It was more difficult than w 32gb, but I've got it.

The problem, as I said, is that twrp names it external-sd. Sees the files, makes bckups, but they are nowhere...

I have the alpha version... Have you updated it, maybe?

EDIT: OK, I understand now. You've updated the recovery:good:

I'm going to flash it and try

any issues with 4g/lte radio ?
[Galaxy Tab 4 General] TopTongueBarry:
No issues other than wifi and no predictive text noted so far with g_ding84's rom .

RE 4G LTE - his rom doesn't touch the BL or modem partitions. Does remove CSC. EU LTE bands working fine on t235 and Taiwan LTE bands working on t235Y. The rest of the world is still SOL though, no USA/NA or Latin America LTE bands. Devices (T235 and T235Y) remain confined to original factory LTE bands based on bootloader model and product version.

BRICKED ?

Hi

im using a sm-t235 device and i installed twrp according to the post

booted into recovery trwp worked well, did not install su update

wanted to make a full backup of every partition, selected all and selected to install to internal sd, since i dont have no external sdcard

i set it and left it there and connected the charger

i looked at it now and its black

device is not responding to any key combination !!!!

what can i do ?

never mind its working :) i waited took 452 seconds for the backup

---------- Post added at 05:38 AM ---------- Previous post was at 05:20 AM ----------

what is strange that my backups have vanished after reboot

i made the twrp full backup and i checked the directory and the backups where there, now i rebooted and i dont see them there

using internal sdcard ... probably thats the problem

strange ... terminal emulator can see the content but not ES File Explorer
[Galaxy Tab 4 General] interstellar22:
It does work if you download the correct versions i guess, knox removed 2.5 and the other 5.2

I removed a lot of other stuff after that was done

And now i am trying to remove even more stuff :)

The rom seems pretty skinny at the moment :)

Take a look at this too

https://docs.google.com/spreadsheet/lv?key=0AnO2-4y6yE1gdDJRekl4QmkyNmIzUmRvX2h3UDVkQXc#gid=0

By the way i am using System App Remover to do this. Its working wonderfully

Also try PerformanceControl.apk if you just want to freeze packages , works like a charm also.

Hi,

I ported CyanogenMod 12 to the S5 Mini G800F (Exynos 3470).

Interstellar22 asked me in the G800F CM12 forum, if it is possible to port CM 12 to the T235:

http://xdaforums.com/gala...g800f-t3083493

I think it is not that difficult and I would help porting it. But it needs a developer who owns this device.

So if someone is interested to work on this, just give me a short reply.
[Galaxy Tab 4 General] interstellar22:
Can i help you ? I am not a CM developer nor android but i think i could help with testing.

Would be really really awesome to see CM 12.1 on this device.

Untill them im going to stick to this slimmer rom i ended up with :)

Here are some screenshots :

[Galaxy Tab 4 General] aftnoon2:
Hmm... What seems strange to me is that you can't see the bckp on the internal sd.

My case is just the inverse : I can't see it if I make it on the external sd, as I said some posts before. Apparently it works, TWRP shows it in its file manage, but it dissappears after reboot.

I can make it on the internal, by parts. But, when I try to copy it to extSd, Root Explorer says it's impossible.

That's the only thing I can't copy to external!?
[Galaxy Tab 4 General] hennymcc:
I have ported the CM12.1 Custom ROM from the S5 Mini to the T235(Y) now.

I do not own a T235 so I cannot test the image.

As a first step it would be nice if somebody could try the TWRP recovery that I built:

https://www.androidfilehost.com/?fid=24052804347765552

It is different from the recovery in this thread as it contains a custom kernel and not the stock one.

If the recovery works I will also upload the CM12.1 ROM to androidfilehost and you can try it if you want.

As I don't want to hijack this forum for the custom ROM, please send me a PM with the results.

If the feedback is positive I will create a new thread for the custom ROM.

"6). Flash TWRP_2.8.1_SM-T235_and_SM-T235Y_recovery.tar using Odin3 v1.85 - use PDA/AP "

DONT choose "PDA/AP" TRY to choose "BOOTLOADER"
[Galaxy Tab 4 General] thisisapoorusernamechoice:
Wrong. Don't use BOOTLOADER. Use PDA/AP. If you try to use BOOTLOADER, the recovery won't install correctly, like what happened in those pictures. That's not TWRP recovery, that's the stock recovery because TWRP didn't install correctly. Use PDA/AP

Hi [MENTION=535343]all[/MENTION],

installing TWRP on my T235 works fine, in TWRP installing UPDATE-SuperSU-v2.46 too.

But after booting i can't start SuperSU, is stopps automaticly. When i start to launch SuperSU, it also stopped, everytime.

I have tried to install SuperSU 3 times...nothing...

Any Ideas?

Version T235XXU1AOB1

Build: T235XXU1AOD1

RootChecker tells me, Root ist not probably installed on the Device.

Thx, Franky

[Galaxy Tab 4 General] FrankyBerg:
It don't works, same with this version.

Next try, Factory Reset, new Rom Installation (LTE SM-T235 XXU1AOD1 DBT Region (Germany)) with Odin.

TWRP installation works, SuperSU 2.46/2.49 Installation works, but after reboot SuperSU stopps.

I don't know why.....
[Galaxy Tab 4 General] TopTongueBarry:
Not sure what causes a device to exhibit the behavior you describe, but mine acted that way after going back to stock 4.4.2 or gding's rooted 4.4.2 from CM LP 5.1.

Good news is once I made it somewhere through the steps I describe below, the device has been operating perfectly, and it's rooted.

Try replacing TWRP with this unofficial version (2.8.1.0) for the T235 (attached tar - use odin),

remember to boot into recovery first before the system loads.

then install SuperSU 2.46 from recovery. . You might have to do 2.46 a second time. Can't remember.

If you don't have root after booting up, then install supersu from play store (without rebooting first), then boot into recovery and install the supersu 2.46 zip from recovery.

When you reboot you should be able to open super su and be prompted to upgrade the binary.

Somewhere along that winding road, you should get your root. I can't remember what part of the sequence actually fixed mine.

For now, I decided to leave mine with twrp 2.8.1 unofficial installed since I'm running 4.4.2.

Please let us know the results.

[Galaxy Tab 4 General] thisisapoorusernamechoice:
No it will not work. You must use firmware only for your model. Odin won't let you use firmware from any other model because it's smart enough to know that if it did let you do what you just attempted to do, you would hard brick. You don't want to hard brick, do you?

Anyone checked rooting with this method at Lollipop 5.1.1 on SM-T235? Will it work?
[Galaxy Tab 4 General] thisisapoorusernamechoice:
Most likely it will not work. The 8.0 models had pretty much the same exact root method for KitKat and it no longer worked for lollipop 5.1.1. It has something to do with selinux and certain other security aspects of the 5.1.1 kernel. 5.0 is easier to root. I'm not saying it will be impossible to root this new LP build, I'm just saying in all likelihood someone will have to modify the kernel. Check out moonbutt74's rooted LP kernel thread for the 8.0 models to see what I'm talking about

But the worst thing is that something strange occurs, because I can't go to Recovery again, only to Download mode. This behavior disappeared re-flashing 2.8.1 version...
