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.

Hello,
As the title says, How do i unlock my Samsung tab S from Sprint so that i can use it on AT&T or internationally? I've searched all over google and this forum itself but i couldn't find a post that explains how. Is it possible to unlock this device by adb or other methods of unlocking such as editing the hex? Any help is very appreciated!
I'm sorry if this post is in the wrong sub forum or anything. I'm new here.
Best regards.
Possibilities
This is what I found out:
The chip in my Sprint Note 3 and Samsung Tab S 10.5 is similar and when compared the base bands were different. I unlocked my Note 3 using SSU. I tried the same on the Tab S it did say unlock but nothing happened when I installed a Local SIM ( Airtel )
The other thing I would like to point out is that SM-T807V, SM-T807R4 and SM-T807P all use the same chipsets i.e, Qualcomm Snapdragon 800, and one has the possibility to choose the GSM/Global-Mode on the SM-T807V( Verizon ) I am not aware of the U.S Cellular (i.e,SM-T807R4) though. If someone could shed some light on that.
So I would assume there are 2 ways to go ahead with this, one would either be to downgrade the baseband to that of the Note 3 then install Android 4.4.2 and then use SSU to unlock ( not to sure on this method just gave it a thought though ) and the other would be to flash the ROM on the SM-T807P with the Stock ROM of the SM-807V but then we are road blocked by the Kernal so possibly we might need to fabricate a new Kernal for this.
This is my first post on xda Hope what I said has helped. Do let me know if anyone has any development on this because I am stuck too.
Several issues with the plan.
You are unlikely to be able to flash the baseband from the Note3. There is no firmware available for the t807v and no source code.
How about the SM-T807R4 ? Can we use that ?

I'd be pretty sure the bootloader would reject it.
But doesn't the SM-T807P have an unlocked bootloader?

It does, but the carrier versions seem to be more picky with what they'll flash.
The only way is to try it. Make a twrp backup then go for it.
why the the Exynos 5420 is so bad compare to the qualcomm snapdragon when it comes to optimization?

Sorry, I am new to all that but i could give it a try. I'll let you know sometime in December the Tab has gone in for a service, the battery seems to have expanded and my top left screen has poped out and then the touch stopped working and my screen went all gibberish.

Hey i had called sprint and all they told me was that this device isn't ment for global use and it only supports CDMA and LTE, and that was a shocker because the verizon one supports global use
Has anyone come up with an unlock for this yet ? I am stuck with a locked device ??
Hi,
getting my hands on a 520M - I cannot find info for twrp/recovery info stating specifically a given version works on the M model. (this is a latin american regional model as I understand it), but the phone comes unlocked, assume it is 6.0 though I can upgrade to an early 7.0 version (avoiding the u2/u3 bootloader issues).
Can/might it work with https://forum.xda-developers.com/sa...fficial-release-twrp-recovery-galaxy-t3648152 ? Or looking at it another way, are there any hardware differences that might make it likely to have issues?
Any insight appreciated,

From my understanding the letter behind the SM-520x just marks the region, the hardware used should be the same however. I would try it, but make sure to download your stock recovery, so you can fix it, just in case it doesn't work out correctly! Hope i could help
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?

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
Hello!
I recently purchased an Note 10+ model SM-N976V, from Verizon. It's possible to flash an unlocked firmware to remove all the bloatware that came from the carrier?
For example to flash the SM-N976U or U1?
Thanks in advance for the help.

So ... your intention is not what you initially stated.
The below link shows all the firmware available for your SM-N976V with and without carrier. There is not any release for Nicaraguans so you shall select the one that fits you better. Just select between the ones without parenthesis (no carriers).

Look into changing your CSC, I am searching desperatly to find a way to root this device. First it doesnt support 5G nationwide (I have a screenshot of the verizon rep saying it supported both MM 5g and nationwide) second its slower than my s8+ with a safestrap rom clearing the bloadware. This is a phone with 12gb of ram and its out preformed in both speed (network and device) by a Galaxy s8+ with some custom firmware. Honestly I am to the point where F____K knox ill root if i get the chance.
Any updates? Has anyone found a way to get unbranded debloated firmware on n976v
That would be through SamFwTool. Bootlogo remains and many retarded settings and bloat remain on all leves put there by the makers of the device and chips, without our consent. This bloat is used to spy on the user and report back telemetry and marketable data back to someone who is totally misusing this data and should be convicted for it.
To truly own your own device that you have paid for with your own hard earned cash, sadly some idiots are preventing your legal right.
We should start a classaction lawsuit against everyone who are guilty of this, as well as convict them of restricting our Right to Repair. Separately convict them for wasting precious metals and polluting the environment.
They must release an unlocked signed bootloader and firehose programmer. Until they do, they are BLACKLISTED from ever getting any money from me or anyone of the people who constantly ask me what to buy.
If the device is U4 or lower there is hope to unlock the bootloader, root it, and completely modify it. Do not brick it in the process because the idiots have put mines inside the chip as part of their security scheme which really is a mafia extortion scheme to drink your blood like vampiers and keep you in the matrix under their control and steal your money.
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.

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 ?
