SuperSU for broadband' sm-t805k/t805l/t805l

Hi, I am curious if anyone can answer this question.
I am a deliberation from obtaining the Tab S version SM-T805K/SM-T805S/SM-T805L launched in Korea with the Exynos 5433 processor. The article here explain this product: phonearena . com/news/Speedier-Samsung-Galaxy-Tab-S-with-Exynos-5433-processor-and-LTE-A-to-be-launched-soon_id61316.; this aricle has an inacccuracy probably from translation, but it supports 'broadband LTE-A', which combines three LTE bands, instead of two like the regular LTE-A for 1.5x increased throughput. Anyway, the release is similar to the Galaxy S5 'broadband LTE-A' with model number SM-G906(S/K/L)
Obviously chainfire's autoroot package for the SM-T805 doesn't work due to different processor.s However, it shares the same processor as the Note 4, so I am curious if there is a method to botain root suing existing downloads and by using TWRP. This amounts to a general question. Is root processor-specific? Does one of the root packages for Note 4 work? Or if a new root package needs to be written for the model altogether.
Please let me know your thoughts.

No the root method is not cpu specific, but it is device specific. However the TWRP method is not as long as there is a twrp version for your device that can be installed. This requires an unlocked boot loader, it's not common for Samsung to lock bootloaders. It's usually only US models that have locked bootloaders.
There is a firmware update for the SM-T805S at Samsung Updates, if you download it, extract the recovery image from it, send it to me and I'll build TWRP for your device.

Wow thank you so much! I have linked it here.
https: // drive.google. com/file/d/0B2CszRKCbxDSM0RuVHI4SHlfWTg/view?usp=sharing
Just for my own clarity, the TWRP version is not CPU or device -specific, but requires a version that can be installed; would you please care to elaborate?

Ah, there is some ambiguity in the thread.
So, the TWRP recovery itself is device specific? and then rooting can be done by sdcard method in TWRP with current version of chainfire's SuperSU zip?
Thank you.

To boot twrp or any recovery it has to be built for a device using files specific to that device such as the kernel. It has to built and configured so that the kernel can boot and then boot recovery. It needs to know the partition layout of that device and such things as the display resolution.

Ashyx is an awesome recovery builder. He built many recoveries such as a twrp mod and also twrp for snapdragon tab s. Without him, some devices may never gotten an custom recovery

I notice that the partition structure seems to be slightly different in the new version.
When you get your tablet I will need you to run a command on the device to get some info.
Hopefully then I can build it.

Just wondering, can it be done from the device itself (no ADB)? If so I can try to get someone to do this on a display model, but availability is questionable. Plus, for some reason, the SM-T805S model has mysteriously disappeared from the Samsung Korea website in the past couple weeks (http:// www.samsung. com/sec/consumer/mobile-tablet/tablet/filter/). The SM-T805K seems to be the most available.
This is the model I am most likely to get. If I got the SM-T805K is there a way to get a hand on the firmware through Kies or other means?
Could you post your commands here? Someone with the device is bound to read this forum and run the commands, but it may take a while. But who knows
Thank you for working on this! :good:

The s,k,l variable is probably just carrier variants. The actual part of the firmware I need is likely the same.

Yes, they are are carrier variants (SK Telecom, KT Olleh, LG U+).
So, does it require ADB to do? what were the commands? :fingers-crossed:
(I spose PM if needed. Thanks!)

You can run the commands on the device itself. It would be best if you have the device because the output would be quite long so a screenshot would be best.

Sorry I havent gotten back sooner. I will report back here when I get the device. :silly:

No worries

Sorry to jump in. Just one question. If the tab is designed/locked for a specific carrier, is there a way to unlock it to any carrier without changing the original ROM?
Thinking of buying this model also, however, im not from Korea!
TQ

I've read on other forums that people have used their korean-carrier device abroad with foreign sims without issue.
This si just a conjecture, but I wonder if we load a custom rom if the device would even be carrier locked anymore. If we delete the hidden.img and cache.img from the rom, if this would solve it? Also, I have seen rooted apps that claim to unlock your device. For me, I consider calling the carrier to have the device unlcoked an option as well.
Using this deivce in the United sttates it is more relevant to note the LTE bands. AT&T would be the only compatible arrier on band 17, and the network would not support LTE-A or broadband LTE-A, but LTE-A is only available in three cities as far as I know.
I am viewing this forum from the SM-T807 version, and the lag is ridiculous. I don't believe it is the bloatware...

This forum is terrible for lag, due to all the java crap and ads running on it. The stock browser deals with it the best imo.
However I use the XDA app which provides a smoother experience.

I'm sorry to disappoint. No, I haven't. I was just thinking of getting one the next time I go. depending on the circumtances and this would give me time to do something with the 6 tablets that I currently have.
Ebay acquired a site called gmarket.co.kr a few years back where retailers in south korea sell crap online; shipping is only in-country, but the other obstacle is making payment; you owuld have to wire your funds internationally, but there are fees on top of fees depending on how many banks it has to cross separate from daily forex changes. The cost for a single unit would probably end up to be a thousand dollars. For the shipping, I know people who are among the 27,000 american military deployed over regions in south korea, and through them shipping can amount to a APO or FPO address with USPS Priority Mail.

Need basic info on CSC codes (please help me understand them correctly)

Ok so I really y need your help guys!
I've asked this question a few times in the past about other phones I ended up not keeping, but I'm now intent on making this work.
I'll keep it simple: can I flash a Canadian CSC on a Global phone? Will this brick the phone?
I don't quite fully understand how the CSC relates to everything else, but the times I tried I couldn't get the CSC to change. Plus I'm concerned because I have a dual sim model (which doesn't exist in Canada) that is Exynos, where the Canadian model is a SD.
Through my reading I think it could work but I don't want to have a $1000 paperweight in the end, but I'm have piss-poor reception, Samsung Pay doesn't work, VoLTE doesn't work, I can't block phrases in SMS and the list goes on. I want to try this to see if it helps anything... Failing this I may cut my losses, sell the phone half-price and just get a non-Samsung device; I'm getting so aggravated at this it's not even funny.
Thanks!
PS: if you are wondering why I didn't buy a Canadian phone to start with, let's say it's a complicated answer but can be summed up by the dual SIM cards.

A CSC defines that carrier settings of the phone. As long as you use official Samsung firmware and do it properly it will not brick your phone. Look at sammobile first to see if Canada has a stock firmware. However, doing this will mean all data is lost, are you flashing carrier based firmware or your country's global software?
I just did a search and on the S8 there was no difference between the single sim and dual sim softwares and on GSM arena it classes them as the same. Do you the have snapdragon or exynos version?

I don't mind data loss, I have back ups and really not much on the phone anyway. Canada has stock firmwares for each carrier, so to answer your question, carrier based. But my huge deal here is the different configuration between what is available here and what I have: I surely can't flash the entire firmware based on a canadian phone... I would lose my dual SIM and surely the difference processors would brick the device. But I'm not really sure if I can mix and match, i.e. pick a CSC for my carrier and everything else (PDA), and if I can, what do I chose?!
See where I'm at... because I can't flash the entire firmware I think I'm s.o.l.

I'm afraid the situation isn't that good for you.... I am assuming you have the Exynos varient since I cant see a dual sim version of the snapdragon variation which means no Canadian firmware is available for your device at all. Since I'm in the United Kingdom we usually swap our CSCs with ease but it appears if you didn't buy the snapdragon version your out of luck at least for now. I'm sorry I couldn't be of more help you could sell and get the Canadian version but you won't be able to dual sim or get another phone I left from the S6 to oneplus and had a really good exprenice but that was on the 3T so I'm not sure what they are like now
Again sorry I couldn't have been more help:crying:

Flashing generic Samsung firmware to carrier branded Tab S4 (SM-T837T -> SM-T835)

I think this has been asked before in a different way in this section but no real response yet. I did some research in the other Samsung device forums and see that often it is possible to remove branding or switch carriers adjusting device ID and bootloader etc. But no idea how to do it for the Tab S4.
I'm sick of waiting for slow updates through T-Mobile (or any carrier) and would like to fully unlock it's potential with Android 10 rather sooner than later. I bought this device second hand network unlocked.
Any short or long answer to these questions? Can it be done? If so where to start?

Am looking to do so, with the t835 you will have full calling functionality,,,

The short answer is no.
I've tried that after I found my T837V can be successfully loaded with T837R4/T837T/... firmware. I thought maybe I could flash stock firmware of other versions. But if you do that with any firmware other than T837*, you will get "secure check fail pit" error. So sadly no.

Thanks for the response! So it does mean you can freely flash T837 versions which could mean I can just wait for the first version that comes out with android 10. Any first release should work. Right?
Turkey version has it:

T837 is Turkey version and I've tried it. It can't be loaded, maybe it need to be T837x which are all US variants.
As for Android 10 update, I think this will work. I'm waiting for the first one who gives the OneUI 2.1 update. So far the Verizon version(T837V) seems to have the most active firmware updates.

In the USA, SM-T837 ARE carrier tablets.
There are the SM-T837A, V, and T; ATT, Verizon, T-Mobile. TheSe are locked to the Carrier. If you have them unlock it, OTA upgrades are over. If you know how to hack the firmware, you can write over the carrier version. The best way to go is probably custom ROM AND ROOTING. But in other nations, it will probably work to write a different Samsung ROM. The SM-T835 HAS no US version, so you can probably write any tab s4 Factory ROM to it.
The USA HAS so many cellular devices, the rules are strict. And, the carriers sell the devices pretty cheap. So, they want them to stay with their service.

T-mobile update for android 10 finally out just got it

Question Flashing ROM on Fold 3 - chinese to australian

One of our Chineese suppliers has gifted me a New Fold 3. The issue is the stock Chinese Rom, or rather the restrictions that come with it (nerfing most google based services, and apps i use all the time.). The device is great but restrictions applied give you a feeling of a second class android user, with core sevices absent: Play store, youtube, gmail, maps, chrome, android auto., can't even apporve family link download requests from kids. etc. etc.
I have made the choice i would rather go back to my S21 if i can't resovle this issue, as phone is useless like this.
Advice required on Loading Australian Rom via odin.
The phone model is: SM-F9260 which only seems to have overseas Rom available for download. Can i successfully load a ROM made for model SM-F926B (Australian) on a SM-F9260?
All the how to guides specifically say jou must select the same model number, and i don't want a brick it. Will have mud on my face next time i see the supplier if i have bricked their gift to me.
Any feedback/advice from users with more experience with odin and flashing would be appreciated.

Both are on Snapdragon CPU so shouldn't be any problem to flash it with PIT over the Odin.
But I never done it so I can't give you 100% answer.

Update: The AU version gave me an Auth Failed in Odin. Chances i could have resovled by unlocking the Bootloader which i didn't want to risk tripping the e-fuse. I ended up just using the Taiwan version which had the identical model number, and falls in the same region as China. Odin flashed without complaint. The taiwan version has no restrictions on google services, and once you set the language its hard to tell it from a regular AU one; unless you know what you are looking for that is.

Technically there are ways, just it is very grey as to when/how you trip the e-fuse. Some say if you simply unlock the bootloader and restart, others say when you load a bootloader that doesn't match model numbers, or is older than your current, or isn't offical samsung one. I personally don't know exactly. I do however know that i didn't trip the e-fuse when i loaded the taiwan version, and i didn't have to unlock the bootloader in developer options to achevie this.

you won't have the chance to trip. there is some check before the boot image is integrated. so it failed showing some error, auth or secure check failed etc etc.
if you flash variant home csc you will trip

TBH, I consider the Chinese version is the best version above all other region. The dual sim is enable on Chinese version, 512GB is the only available option.
As for google service. You don't need to change the Chinese firmware to Australian to enable it, the GMS is pre-installed. All you need to do is to find a way to install the google series apps as apk by yourself, it would work just fine.

BTW, the only version that Chinese region Fold 3 can change is the HongKong firmware, all other regions are not available. If you use Chinese region Fold 3 in Australia, the only thing you need to concern is the Samsung Pay, but Samsung Pay is fixed by the region and cannot be changed by switching the regional firmware.

Each to their own, if you like the chinese version great. I hated it, restrictions in every aspect of the firmware. I personally am unsure how you rate the chinese version better, when it is loaded with restrictions and hard coded settings that can't be changed, or if they can it is really a sub par workaround. Settings that are not present in standard android builds. What exactly does it have extra that makes it better? If you like it thou that is all that matters.
I loaded the taiwan version which yes is really just the hong kong version. No restrictions, no issues. Now it works just like any other standard samsung android build, you get in AU. Yes samsung pay that use the firmware version doesn't work great, but i prefer google pay anyway. No need to stuff around with downloading apk files from third party sites, for core functions. No need to even enable developer tools.

The chinese version sounds like driving a ferrari on a go karting track.....

Can you flash the Chinese or any international dual sim version to work in the US ?

Question A52s 5G (SM-A528B) Debranding

Hello is there any free way to debrand Samsung A52s on Android 12 One UI 4.0? I also dont want to trigger the KNOX flag. My current CSC is PRT (Poland (Play)) and I want to make it XEO (Poland). I already tried some methods with phone call codes and none of them work. Is there any way to do this?

If by debranding you mean removing bloatware and changing your bootanimation etc, just root your phone and do those things. You'll easily be able to find tutorials on how to do all that for your device.
Now, if by debranding you mean that you want a stock android feel, then sorry but your device doesn't have any custom Android development, so you can't install a stock/custom ROM.

By debranding I mean get full stock Samsung firmware which CSC code is XEO, and my current CSC code (PRT) and both are in OXM - multi-CSC so I need to change the CSC code, but tools that can do that are paid, like SamKey so is there any free way

I don't have much experience with oneui Samsung devices, so I've got no idea, sorry.

There is nothing about how to do it just link to ADB

Then there's probably no free way to do what you're trying to do. Also in that post the person claims to have the same csc code as you (prt), and samkey did not work for him.

@Raflen100 Hello! Have the same problem as you: purchased a carier SM-A528 whitout realising the consequences and am no bugged by the super slow updates. I think i am on the same OXM firmware as you. Want from DTM to DBT. My attempt to simply flash DBT and then use dialer codes to switch the CSC failed all.
SAMkey is no option for me, as i don't have any idea about the background and don't want to ;-).
Also: don't want to trigger KNOX.
Since i use a different carrier, i just want a stock SAMSUNG and don't have to wait for weeks for my updates.
If you found a way in the meantime, that would be good news.

Actually, there is a way that was created in the meantime. Around may 2022, developers of samfw.com created the SamFw Tool. It can change the csc of phone through ADB without root, so it does not trip KNOX or wipe data, which is awesome. It worked for me really well. Just make sure to use the non-root CSC change.

Hello @Raflen100, thank you very much. That looks actually very interesting. I currently seem to be not able to find a version without malware, but i'll keep it on my watch list. Can you accidentally tell from experience, that the [provider] CSC change work without need for rooting? My impression so far is that the provider CSC can not be overwritten by flashing, even after having removed the filesystem, so may be stored somewhere else? Or is the SAMSUNG server telling it to the phone, based on it's IMEI?

Answer to your question is very simple, samsung has multi-CSC roms, so flashing one or another won't change anything on the newer phones. There still are single CSC roms, but there are really few of them. And yes, I think it's based on IMEI, because you can't change the entry for the factory CSC, it will always remain there, but you can change the current CSC of the software just by using this tool.
