[Q] Complete Roundup for SM-T23X - Galaxy Tab 4 Q&A, Help & Troubleshooting

I'm new to this device (and SM in general) and I have owned a Nexus 7 (2012) wifi and so this lack of (stable) original development for SM-T23X is a bit too much for me to take in.
Can anyone here give me a quick rewind of what's happening?
I have a SM-T231 (Cellular Model of T230) purchased here in India with 4.4.2 (T231XXU0ANE2) with date of 7 May, 2014 - no earlier build exist for my region.
From what I've been able to gather, the lack of development is chiefly because of the Marvell Hardware with a cap on the Kernel Size. But still, I see 3 different versions of TWRP in the forum (partly working, need advice). So can we say that we're close to getting a stable recovery environment?
And last question, since no other previous firmwares are available for my region - what should I do to gain root?

[Q] GT-P6210 Canada ICS question

Following the recent success with updating my UK model P7500 to ICS using the German official software and Odin, my brother in Canada has asked me if the same sort of thing can be to his P6210 Canada version. It appears that Canada is another Samsung Tab drought area, and he says that his battery life is below expectations. - the saesman in Future Shop told him months ago when he bought it that the upgrade to ICS was only days away - pretty much the same story that I was told in the UK, but as usual Samsung have let us all down.
There is a UK version of the ICS upgrade for the 6210 that was released months ago I believe, so I was wondering if someone out there could tell me if the update is suitable for his unit... The build number of his is HTJ85B P6210XXLB2...
I found Odin a delight to use for the non-technical like me, and he is much the same - so an Odin based update procedure would be ideal.
So...... Which is the best update to use for his machine?
Thanks
This is not the correct section as this is for the original 7" tab the P1000 and variants. You need the Galaxy Tab Plus forum and they should be able to help. Also when posting questions please check if there is a Q&A section before posting in General as if there is they belong there.
Thanks

[Q] SM-T530NU Stock ROM Europe?

I bought an SM-T530NU in the US, thinking it would work OK in the UK. The only problem is that it doesn't get Wi-Fi Channels 12 and 13. I asked if there was a solution to this here but didn't get any replies that helped.
I'm wondering if there is a stock Europe ROM I could use?
Note that this is the Galaxy TAB 4 10.1" with Wi-Fi (no 3G) and an IR module.

I gave you my tuppence worth on the Wi-Fi channel question just now, but as for this question. I'm about 95% certain that unfortunately for you, Samsung only officially releases firmware builds for the U.S. (XAR Region: Cellular South) and Canada (XAC Region: Canada) for this tablet model. Now there is a firmware build (analogous to but not the exact same as a stock rom) for the UK region (BTU Region if I remember correctly) for the regular SM-T530, but that one doesn't have the IR module so you'd lose that functionality. That's the deal for firmwares.
As for custom roms, repey6 made a trimmed-down but mostly unaltered stock rom for our model here. However it's based off the U.S. firmware build so I don't think it would offer you the solution you're looking for. If you're feeling particularly brave, Cyanogenmod 11 (designed for SM-T530) is working for our model too, if you want a drastic solution.
Thanks, I've replied in the original thread. I'd like to keep with stock for now.

Frankenstein device

Hello everyone
I had Note 4 with Exynos chipset (N910C) with no brand (European version).
After some issues with LTE connections and SIM card recognition I have bought used N910F motherboard and installed in my device.
First boot shows that motherboard is from Italy device with Wind operator applications installed.
Next I flashed device but forgot to record IMEI, modem version and bootloader version.
I have restored device using Samsung Kies and during restore process Kies reported device as:
PDA: QG3
CSC: QG1
PHONE: QA1
After restore system setting shows:
Model: N910F
Modem: N910FXXS1DQA1
Version number: MMB29M.N910FXXU1DQG3
1) Now I have a problem: should I use TRLTE roms or TRLTEXX?
When I put "Note 4" in TWRP website search it suggest "Samsung Galaxy Note 4 Qualcomm (trlte)" - so it is TRLTE device?
On the other hand most of N910F images are tagged as TRLTEXX.
2) Can I mix TRLTE TWRP with TRLTEXX ROM image (and vice versa) or they should always match?
3) I have tested few roms and faced problems with not working camera. I know that latest official Android version for Note 4 was Android 6.1
and most roms (RR, Lineage) are based on Android 7.1 If this is the reason of problems? Because official Samsung kernel with working camera
supports Android up to version 6.1 and customs kernel used in 7.1 have some camera issues?
4) What is the relation between kernel version and Android versions? Its like Android 6.1 requires kernel 3.x.x and Android 7.1 requires for example versions never than 4.x.x etc?
I will be thankful for answers to my questions. I know that they may be naive for experienced users but I try to good understand the process,
rather than blind flash roms until device will work.
Your device is basically n910f now. You should use twrp and roms for n910f
Your camera is nonfunctional because Exynos based units use Samsung's ISOCELL modules, and Snapdragon devices use Sony's image sensors. Your network connectivity should be gone as well for that reason.

Ok, but still, if it is TRLTE or TRLTEXX because both tags comes with N910F roms.

By network connectivity You mean that antena design is also different and will cause signal loss?
I forgot to mention that I have also switched front and back camera to used ones from N910F.
From original N910C only body, USB port and scrren left.

Precisely. If you replaced those too, you should have no issues
Questions 1 and 2: Both use Snapdragon chips. Trltexx is the unlocked international N910F, while the other one is usually sold by carriers (T-mobile, AT&T and the likes). You should be able to mix 'em with no issues.
3: To get devices working on non-OEM firmwares without direct support from official drivers, developers write bundles of code called SHIMs. The camera is one such device, and because in most cases the driver is based on the manufacturer's own proprietary code, it's usually with blood and tears that our dear devs are able to get everything working even as it is. That's why you may face almost-working equipment with AOSP ROMs. You can read more about SHIMs here.
4: "If it ain't broken, don't fix it" applies here. There's no direct correlation between Android versions and which kernel versions they use, and manufacturers are sometimes slow to move to a higher version number because of how little meaningful improvements it brings. Recently, Google has mandated that all devices shipping with a SoC manufactured in 2017 or later must come with kernel version 4.4
Hope this clears things up. Anyone is welcome to correct if anything I've said is in the slightest incorrect. :angel:
Cheers,

Old newbie help!

Hi all,
It's been a long, long while since I tinkered with roms, I think my last one was either a Samsung Galaxy Tab (the original one!) or an HTC Sensation.
So I've recently acquired a Note 4 n910F and can't stand all of the Samsung bloatware, and I'd like a newer version of android for compatibility with newer apps.
So remind me... What does 'stock' mean? Is this as Samsung intended, or as android intended? I'd just like a vanilla as possible android experience that works well.
Help please!

Hey! I don't know if you've already found your answers but I thought I would respond in case you haven't.
In almost every reference you see in this section of xda "stock" is referring to the TouchWiz OS that Samsung phones are shipped with.
True android stock is referred to as "vanilla" like you said.
I use a different model Note 4 than you have but from what I've read it's fairly easy to flash TWRP (custom recovery) on the F model via Odin and from there you can pick from whichever rom suits you. Just be sure you're in the Snapdragon section. There are many different models of the Note 4 and some of them have a different processor called Exynos. The roms are processor specific and you can only use the ones built for your type which is the Snapdragon processor.
One other thing I wound suggest, because of the different variants of the F model, is to take notice of your CSC code. Once you start flashing other roms it may be hard to track down the original code. Use this app to see what it is and that way you can flash the appropriate modem file (or if you need to reflash your stock firmware) instead of just using whichever modem file is provided in the OP of the rom you're flashing. There are many different variants of the F model with many different country codes, just remember that just because the firmware has a newer release date doesn't mean it's the correct version.
TWRP- Found here
Samsung USB drivers for Windows. Needed to connect your phone to your PC- Found here
Odin download- Found here
Development section for Snapdragon- Found here
Fantastic response, thank you. I think I'd like to do without TouchWiz... Pretty much all of my previous phones have been HTC, which either had the HTC skin over it, which was fairly unobtrusive, or barely anything at all. The current version of android and TW on the note 4 is messy.

Is there lollipop available for Samsung Galaxy Tab 4 SM-T231

hi.
i have a Samsung Galaxy Tab 4 SM-T231 8GB, Wi-Fi + 4G UK tablet. it is routed and has no sim lock.
it works fine for phone calls. and general activity BUT its on kitkat 4.4.2
i dont use mobile devices much but one thing i do use them for is discord video to test that my stream is acceptable.
the discord i was able to install from apk mirror does not have video support in voice channels.
So i want to update to lolipop.
I have checked the internet and its quite a mix of info.
i have found that some of these tablets did get a update to lolipop in other countries.
others only recived them if they had a specific version..
so i dont want to update and lose my phone call ability or possibly worse.
So i figured i would check with the good people here first.
this is a 7 inch sm-t231 galaxy tab 4, from the uk currently running a 3 sim. (but is its unlocked)
is there an actual path to update it to update it to lolipop or am i just out of luck?
[ROM] [KK] [SM-T231/T230/NU] + Android 5.0 Lollipop Material Design -{Theme}-
Read this thread carefully !! ROM only for Galaxy Tab 4 7.0 Inch This ROM made to give your device full Android Lollipop look (Theme) lol After installing this ROM all you can see is just kitkat theme every where like a kitkat 4.4 ROM but...
forum.xda-developers.com
think thats just a theme. wont help with functionality of the apps that can be installed will it?
also
this quote from the dev makes me think il lose my phone:
i am sorry for all the users that used my ROMs
all my ROMs not detect SIM card at all
What you want is to move from Android 4 to Android 5: that means you want to upgrade existing Android to a higher version what de facto is a complete replacement of Android OS.
yes thats is what i asked..
and you linked a kitkat 4.4 theme, not a actual lolipop rom.
and it also does not support sim cards.. "which was stated as a needed feature"
so what you linked is not at all what is needed.
but still thank you for your time.
i had already searched for and read that entire thread the other day.
i will just assume that it does not exist and carry on using 4.4.2
