I have been scouring the internet for a while and cannot seem to find a way to revert my tablet back to stock. I tried the Lollipop firmware for a while and wanted to restore the tablet to possibly sell it. I can't find any method to recover it nor the files. The full model number is SM-T520NZKAXAR. It is the wifi only model. Can anyone help me please? I also currently have the TWRP recovery on it.
Thanks.

Thank you but I've looked there. I can't seem to find a match for my model number or any USA model. I read somewhere that the cellular south file will work but I'm a little hesitant to try flashing it. Mine is the WIFI only model.
If that were the case, it would either be a T525 (LTE), or possibly a T521 (3G). So anything listed as 'SM-T520' on Samfirmware should be OK. Having taken a look the US is not listed there. I have seen the Cellular South (XAR), as the possible option. But I doubt it has anything to do with any 3 ~ 4G connectivity, as the T520 has none.
It's possibly worth mentioning that these 'codes' (i.e. XAR), isa CSC Code. e.g. retail location in most cases. So assuming XAR is the USoA then this would be your choice.
Just one thing that you probably already knew, but is it really worth downgrading back to stock? The Knox Flag has already been blown. So NO KNOX on said Device ever again. Which would be about the only reason I could think for downgrading back to stock. Which IMHO would be a touch immoral if you wanted to resell it to someone who otherwise wouldn't have a clue.

def not mine was in deep sleep mode and i didn1t know it and now i use temasek ,it`s out of warranty ofc but bugs and error and lags from bull**** sa,sung apps are gone. cyanogen 13 modded flies like 5 times more than stock i play on tablet do a lot of stuff never had any problem in almost 1 year i can do offline backup a lot of perks.at some point when s3 will come i will sell it like this 32gb sd card leather case,i love this device.so no point going back to stock ever i always flash every new device
Thanks. I may give the cellular south file a try someday. The latest Cyanogenmod is working well. I was having problems with one of the older versions. The touch screen was acting goofy sometimes.
Have you tried https://samsung-firmware.org/?
Cellular South *is* the USA version. If you want to restore to US stock version, Cellular South is what you need. I don't know why they name it that way.

I just successfully rooted my Samsung Galaxy Note 2 using Odin and CWM Recovery.
This is exactly what I did:
- D/L Odin 3.04 and "cwm6-root-note2.tar" and saved them to my Desktop
- Extracted Odin and started the program
- Set my Note 2 to USB Debugging
- Restarted the Note 2 in "Downloading Mode" by holding down Volume Down, Home & Power buttons simultaneously
- Connected usb cord to my phone and computer
- Confirmed that Odin registered connection of my phone correctly on COM port
- Went to PDA, then selected "cwm6-root-note2.tar"
- Then I selected start, or root or whatever starts the process. And voila! Rooted with CWM & SuperUser App.
However, I might be returning the phone so I now need to know how to reverse that process and UNROOT my phone. Can someone please help walk me through that process? Do I need to obtain more files that were overwritten or deleted when I rooted?
Also, I thought, perhaps, I could unroot using the SuperUser app so I chose the option that said something like "Unroot.... etc." All it did, however, was get rid of Super User because when I restart my phone in recovery mode, it still boots CWM-based Recovery v6.0.1.4
Any assistance would be GREATLY appreciated.

Hi,
So you rooted a LTE version, can I ask which version did you have (SHV-E250S / SHV-E250K / SHV-E250L)?
Is it meaning the rooting process of LTE version is same as the non LTE (3G?) Note II?
Also, what is the reason of returning the phone? Did you find something not good with LTE?
Thank you.

I rooted a SHV-E250L. The process went very smoothly. Especially considering I'd never rooted a phone before. So, from my experience, it seems to be the same process but don't take my word for it.
The phone is awesome - no problems at all. It was just very expensive and I was having a little buyer's remorse. I'm over it now. I was also concerned about not being able to use it in the US when I move back, which I am still unsure about. I have asked a few developers on here but haven't heard back yet. If possible, I'd like to flash a US ROM on the phone so that I can use it on the networks there and access the unrestricted Google Play Store... so, we'll see.
Hope that helps.

Brian,
I am living in Korea as well and I have a lot of experience with the Korean smart phones.
To answer some of your questions, you can use them in the states with either a Stateside SIM (assuming your phone is unlocked, you can get it unlocked from the store if you're going to be traveling) or a Korean SIM (obvious roaming charges). I don't think the LTE bands are the same in SK and the US, therefore you wouldn't be able to use the LTE.
In my experience (with my SGS1) you won't be able to flash a US or Int'l ROM on your Korean model. The internals might be closer than the SGS1 and it's variants were but I wouldn't do it unless you have the Note2 Korean ROM ready to flash back with Odin in the event it won't boot.
You can get unrestricted Play Store access now. You need to download MarketAccess. Google it. it Allows you to basically tell the phone what network it thinks it's on.
In the event you ever need to unroot your phone, you just need to use Odin to flash the official firmware.
If you need anything else, let me know...

Most likely Tegrak will have a kernel for this device before too long. You would then be able to use the Odin software to root the phone. The process is the same for both.

Thank you so much for the answers. I really appreciate it. So, you're saying for sure I will not be able to use this phone's LTE capabilities in the US on any network? If so, that's a huge game changer for me... I wonder what LG U+'s return policy is... I know I can just transfer the phone to someone else here in Korea when I leave and pick up a Note 2 in the states when I go back but I feel like I'd be losing a lot of money since the cost of the phone is spread out amongst the monthly payments here in Korea. Are there any phones that will work work both on SK LTE and US LTE?
Regarding un-rooting my phone, don't I need to get a hold on the official firmware before I can flash it with Odin? Or is it stored somewhere on my phone? All the official firmwares I've seen on XDA are for the N7100 not the N7105. Any suggestions?
Thank you, again, for all your support. You rock!

No problem, glad to help.
I am also looking for the firmware online. I haven't found it yet. PM me your email and when I find it, I'll send it over to you.
All info I have read says LTE is different. The 3G would still work just no LTE.
Idk what LG's policy is, but you could take it to Samsung a/s in the electronics market to revert it if needed.
Good luck. I might know someone who could take the phone of your hands next year if you want to go that route.

Good info here. But what about his flash counter? Will that be reset to zero by flashing stock from via Odin?

SHV-E250S problem.
Hello SHV-E250S/K/L users.
Does anyone know where I can download an official factory stock ROM for my SHV-E250S ?
I have an IMEI missing issue, and EFS file deleted issue. After wich i have a black notice on the screen and no boot logo or turn of logo, it just switches straight away after pressing the button.
No network or IMEI(((
I just came back from the Samsung official service center, and guess what, they can`t help me. They say i need to flash an original factory rom, i even brought them the two roms i downloaded from the: www.sammobile.com/firmware/?page=3&model=SHV-E250S&pcode=0&os=1&type=1#firmware
And they said that these are not official factory roms, that they are custom, all thaw when i flash with one them, and go to recovery mode, my current binary changes to official. Don’t know why but everything else stays the same:
ODIN MODE
PRODUCT NAME: SHV-E250S
CUSTOM BINARY DOWNLOAD: Yes (37 counts)
CURENT BINARY: Official
SYSTEM STATUS: Custom
DON`T KNOW HOW TO FIX, AND WHERE TO GET FACTORY ROM((((
Would appreciate any help!
NEED Pit.

I recently bought a new "Samsung Galaxy S III 16GB SGH-T999L 4G LTE White - T-Mobile" from Oakland Wireless via Amazon. This is for my fiancé, to replace her broken iPhone 4s. After popping in her T-Mobile sim card, the phone seems to work fine. However, the WiFi calling feature seems to be missing and when we try to perform a software update it ends with "process failed". The installed Android version is 4.1.1.
She went to a T-Mobile store to see if they could help. They were also unable to get the phone to update, and eventually told her that it would never work simply because we didn't buy the phone from T-Mobile. They also told her it would only be a talk and text phone, and wouldn't get data service. However, this last part is clearly false, as she has been using data without any problem.
Does anybody have experience with this issue? Were the folks at the T-Mobile store correct or mistaken?
Also, assuming they are correct and the phone can't be updated over the air, can I just download and install a stock ROM with the latest version and WiFi calling? I have a custom ROM installed on my Galaxy Exhibit, so I am familiar with installing ROMs, but my fiancé doesn't want a custom ROM, she wants stock.
Look in the t mobile s3 section there should be a Odin file you can flash (stock firmware)
Sent from my SM-N900A using XDA Free mobile app
Well first of all the T999L released with 4.1.2 so something doesn't seem right, and it may be why its not updating. To get a better idea of the phone model, can you post a screenshot of the about device section? And I assume you are not rooted correct? Download this app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo scroll to firmware info and post it here as well

Hmmm. Maybe I got the version wrong or maybe it's not really a T999L? She isn't here with the phone right now, so I'll have to get back to you.
I stopped posting the OTA's simply because they're next to useless for us. Fladhing the firmware via Odin has a much greater success rate snd OTA's are notorious for causing all sorts of problems. Just wasn't worth the trouble to post them anymore.
I attached the screenshots from the phone info app. Looks like maybe it's not the LTE model after all? I looked behind the battery, and it also says SGH-T999 with no "L" on the end.
The strange thing is that it shows an LTE mode in the network settings. However, I've never seen it actually use LTE mode, even though T-mobile says it should work at our location (Seattle). Using the Ookla speed test app, I get ~4 Mbps down (the same speed as my Galaxy Exhibit).
I'm thinking about returning the phone if it is not the correct model. I'm curious though, if I try updating the firmware and it doesn't work, can I restore everything exactly to it's current state before I return it? I don't want them to refuse the return because I messed with the firmware.
Ok looks like you got a Frankenstein phone.. That's an at&t bootloader with a Canadian product/model name & T999 build that I've never heard of.. I would just return it or ask for an exchange, not worth it to keep messing with it
Yup. Another one! And its got a csc from the I9300! The LEM build, if I remember right, was the original stock 4.0.4 firmware. But there is way too much conflicting info there for me to be comfortable recommending much of anything.
I just installed that app to make sure it wasn't giving bad info, and it is showing everything correctly for mine.
As for the LTE showing up in the menu, that isnt too uncommon. If you want to know what you are really connected to, check Settings, About Device, Status, Network Type. Best to do this during a large download.
But aside from it being a franken-phone, everything that is related to the T-Mobile model points to it being a non-LTE T999.

Hey guys, so i recently decided to go back to stock - if i ever needed to service it, so the root flag won't show up. I looked up firmware by IMEI number. Everything without problems.
Since then i feel like i have more signal drops and worse signal overall, am i paranoid or does the firmware actually affect signal strenght? I live in Czech Republic and i flashed International version instead of the Czech one - i used the one searched by IMEI so i wont mess up.
Thank you

Edit* if your bumped you could even try to restore from a backup if you decide it is better. Then if it drops again after the restore you know what to blame. Recovering from a backup will not replace modem or rpm. I would stay all czeck for a few days just to make sure it isn't the system.
Good Morning,
So this is the story, I was suddenly having issues with Cell service people were not hearing me I felt like I had to reset the phone and wipe it all so I thought I might as well ROOT it when it came to downloading the firmware I was a bit lost did not know what was the correct one was i threw out the box,
I flashed one but still have this cell issue I feel like its not using all the bands... I have Tmobile and I do not know if the issue is I am flashing wrong firmware.
So 2 questions
how would I know if I am flashing the correct firmware?
And how would I know if that is my issue ?
Please Someone Advise.

I would test another carrier first, or the same carrier in another area. Also test with different people in different areas. This is most often an issue on the carrier side, not the device.
So my advice: make sure your issue is the device. Only after that we can talk about flashing another ROM.
Thanks @arsradu for your quick reply Its definitely not the carrier I just am not sure what the problem is, I was thinking each firmware has its own optimizations for the bands it should use,
I bought it on amazon USA
And currently flashed
TROIKA_RETAIL_10_QSBS30.62-17-13_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
I tried using LMSA to restore my phone to factory settings and it gives me an error I wish I can just go back to stock clean.

Assuming you bought a US model, which works on all major carriers, your version should be RETUS.
With the bat file that was provided here in the forum, you should be able to fast boot flash it.

It can be the ROM, as well. In my experience though it’s usually not the case.
Anyway, what’s your device model? Is it xt2013-4? Did you make a backup of your original ROM so you can restore it later on?
Also, what is the error you get when trying to use LMSA to restore?
Yes my model number is xt2013-4 no i did not make a backup I uploaded a screenshot of the error message. and I guess I will try reatilUS I tried the simple retail option the last one not sure what retail and retail us differences are,

RETUS with the above linked bat has worked fine for a XT2013-04 I have worked with, I assume it would with yours too :good:
I cannot speak to the assistant error though, never used it...
Side note: don't forget to add the code line for the 10th chunks to the bat.
Does Any one know what are the differences between Firmware's that are made for this phone ? for example
AMZ
Retail
Reatus

AMZ is the Amazon Ads model,
Retail can be US retail with different bands.
Retus is what I flashed in the past on a US phone that worked with all 4 carriers and it never had any issues.
I live in Canada. I purchased an S20 Ultra off a seller on Canadian best buy (open box). I assumed it'd be a Canadian variant, but it was an unlocked US version (U1 firmware). OK whatever, but it meant my Samsung Pay doesn't work, along with a few other calling features.
I downloaded the patched Odin, downloaded the G988W firmware (with XAC CSC) with Frija, added the appropriate files to Odin (used Home CSC), and flashed it. The flashing itself went fine, but when I went to re-insert my SIM...nothing. It didn't even error out and say "No SIM Detected", I just had no coverage, and in SIM manager, both slots were empty.
Freaked out, and eventually flashed back to G988U1/XAA and thank Christ it works now. But my question is...why?
I dug though this forum before doing it to try and anticipate any issues. Followed the instructions to the letter, nowhere said this would be an issue. Couldn't even find any relevant support questions for this issue on this model. Not sure if it's a new development, but I absolutely don't want to risk messing my phone up further if I reattempt.
Bonus question: My CSC info is: XAA/XAA,XAA/SPR. Does that mean that it was originally a Sprint model phone, someone's flashed the firmware to an unbranded version, then sold it off as New (Open Box)?
You can't just flash a firmware from a different phone. The hardware is different, so the way to communicate with it is different. You're lucky it even booted, I wouldn't have expected that even. You're simply stuck with the original firmware and CSC list. Or, maybe you could try with custom ROMS but I wouldn't be so sure about it. Either way, you'll have to use a ROM/firmware that is built for your phone (G988U1).

Huh I thought the actual hardware between U1 and W was the same? They're both Snapdragons. Besides I've seen other posts of people doing the same (tbh, they were going from W to U1, but still)

Oh but you CAN.
U, U1, and W have all been cross-flashable ever since Samsung first introduced universal hardware, starting with the S8

Probably. Very common for online sellers to do.
The key probably lies in what the CSC shows as after flashing W firmware. If it stays as XAA, changing the CSC manually to a Canadian one could possibly make it work

I thought so too, lol
Any thoughts on why my flash caused the SIM issue? Did I maybe just install the wrong version? I don't think I did, I used Frija
Some further research led me to the subject of accidentally mucking up the modem firmware which I might have done

I Just did exactly the same and got a tmobile variant but want the W preferably the samsung factory rom not a carrier one. Which guide did you follow? I found this for the 21 Ultra and expect the steps to be similar https://forum.xda-developers.com/t/...-samsung-unlocked-bloatfree-firmware.4224423/
What calling features don't work in Canada? I have a W variant, live in Canada, and want an U1 to get esim working. I am also looking for a guide to follow to flash my phone.

Samsung Pay doesn't work - that's a big one for me, it's a pain in the **** losing that. Will only accept US ZIP codes when setting up.
Caller ID doesn't work
That extra info you get when texting (like seen/read stuff) doesn't work in the native Samsung text app, you have to use google messages (yeah, no)
I'm sure there's other stuff but those are the main ones
