[Q] Need wifi help AT&T S3

Ok, so I've had wifi issues for awhile with this thing, but apparently the 4.3 update sent it over the edge. (I just updated it last week, since I was out of the country when the update issued).
The issue is, I cannot connect to any wifi, other than my home. Before the update, I could connect to non-home wifi only through various router setting changes, that required admin access to the router. After the update, no matter what I've tried with regards to routers, my home router is the only one I can connect to, and the signal strength is pretty bad on my phone, while it shows very strongly for any other device.
I've tried all the suggestions in just about every thread I could find. I've done several factory resets, I've tried the *#0011# thing. I've tried using static IP addresses. But the phone will do one of two things. After I click connect, after selecting a network, it will say Saved. Or it will try to connect and then go back to Saved, or eventually give the Authentication error.
I'm not 100% familiar with how android is setup, but is there a specific file that I could try to install that might affect this? (Like a driver)
Would replacing the antenna be helpful, or maybe the chip on the mb? Or are those options too extreme?
Any ideas are appreciated.

Nobody has any ideas for me?
Please, I'll try anything.

Still looking for help. Thanks!

Did you try re flashing the firmware? Might be a bug in the software. You'll lose all your data but its worth a shot. I've seen a similar issue like this before on the S III and that took care of the problem.

Do I use odin to reflash....it's basically like installing a rom, right?

Yes, you will use Odin to complete this process.
Few things you should consider though, by doing this it will completely reset your phone to a point as if you just un-boxed it (or a factory reset). I am uncertain about the fact that it may hinder you the ability to receive further OTA updates. Like i said I don't know exactly on that one but that will most likely be stated in a thread that you receive the firmware from. Also, this may be a good opportunity for you to root your phone if it was not previously. Doing this could be as simple as downloading one file vs. another to use in Odin. The choice is yours as there are threads regarding both Stock Rooted and Stock non rooted firmwares. Another thing, consider which version you want. Im guessing 4.3? I was once told going down a version on android (i.e. 4.4 to 4.2) could brick a device... also unclear on that. try doing some research if you wish.

If you have the AT&T 4.3 bootloader on your phone, do not use Odin to try and flash any stock ROMs as this may brick your phone. The 4.3 bootloader cannot be downgraded and attempts to do so with probably brick your phone.
Boot into download mode and tell us what it says on the download screen.

[Q] Flash European Firmware onto Chinese Galaxy Tab S 8.4

Hi guys.
I've got a China-bought Galaxy Tab S (T705C). The current ROM doesn't allow Google Services. Hence, no Gmail, no Google Play store on my Tab.
Can anyone throw me a bone here?
Where do I begin with installing European firmware for the Tab?
1. Do I need to root the device?
2. Do I have to install Cyanogenmod / some other firware loader?
3. Will LTE firmware work on this model? (It's 4G)
Thanks

For reference, would this ROM be correct for the 8.4" Tab ?

1)yes. http://androidxda.com/root-samsung-galaxy-tab-s-8-4-sm-t705c
2) you need a recovery ( TWRP) to install Rom zip file.
3) If the HW is the same I would assume yes. Does support main LTE frequencies
4) yes, Selamba Rom is correct

:good: Dude, you're my hero.
I'll give it a try.

I have the exact same problem, very curious if you are able to solve the issue and how.

Partial progress - Update 11/26

dqs23: If it will be of help to you - here's where I've gotten so far:
My understanding, to this point, is:
1. I need to install a European ROM to use Google services, and Google Play store on the Tab S.
2. I think that the SM-T705C is the same as the T705, just from China. So, I assume that this ROM (French-based) should work:
3. I'll need a tool such as Odin or Heimdall to install a Root program.
Recommended in the above link is this one: CF-Autoroot
4. Upon flashing CF-Autoroot, I'll then be able to install a ROM manager such as TWRP, from whence I can backup and install the custom ROM.
Where I'm currently hung:
I'm using an Ubuntu 14.04 machine, which can't run Odin.
I don't have a Windows machine, or access to one conveniently.
There's a Java based version called JOdin, which I've used, but it hangs at "Cannot extract PIT file."
Using Heimdall alone, I have the same problem - Cannot retrieve PIT file. (Which I presume is necessary to proceed with flashing the Root package. So, it's apparently an Ubuntu/Heimdall issue, perhaps with this particular device.
I understand it's possible to get PIT files from other means, but I'm a bit out of my depth, and don't want to f*$# things up. So, at this point, I'll probably wait and try to get a Windows machine going, and test from there.
Please kindly add any additional information you find here to this thread.

Thanks for the update emfield.
As this is the first time I'm doing a root everything is very new to me. Luckily I have an expert nearby to consult with on the basics.
What I've done so far is rooted the tablet with cf-autoroot but after installed gapps manager I was unable to download the proper gapps (4.4.1-2) as it gave me download unsuccessful error every time.
I guess what I'm looking for is some kind of confirmation from others how they were able to flash it to a EU rom and the steps they followed.

That will not likely happen as China locks everything down, as that product is actually manufactured in China, it will be fully compliant with whatever regulations exist for those products. I got around some of it by extracting the Chinese Odin image and the HongKong image, then I took the Hong Kong Cache.img and placed it in the new Chinese image.
Doing that allowed me to change the csc to whatever country I wanted, in this case Hong Kong, I was then able to get my news and other things in English.
Use 7Zip to create your new tar image, since it is not signed by Samsung you will trip the Knox flag, you will need to root your phone in order to flash GAPPS. The key parts of the firmware are blocked by the Chinese bootloader so rooting is absolutely required.

Hey Lorin, please let me go back a step with your response:
1) By "That will not likely happen", do you mean it's not possible to root and install a different ROM?
I've found a European-based ROM, based off the stock Samsung 4.4 firmware, which is for the SM-T705. (It's here.)
Are you saying that's not possible / not going to work?

2. Sounds interesting. Can you clarify slightly about the "Odin image"? Is that an image of the firmware? (Same thing as a stock ROM?) And where did you get a HK Rom?
Thanks!

Sammobile.com has all the ROMs, I just downloaded the Chinese and Hong Kong Versions and replaced cache.img in the Chinese ROM with the HK version, that should work using a cache.img from Europe. Odin will work with a tar image without the md5 extension. If using Window, 7Zip will create a tar file
If you attempt to flash any other ROM on a Chinese ROM ex. T705C, T805C Odin will fail and knox will be tripped, you can flash a custom ROM but you will lose the radio, no LTE, 3G or 2G

I see.
Were you able to download a PIT file for the T705C? Linux user here, using Heimdall. On Mac and Linux, we're unable to extract a PIT file from these devices.
2. Regarding "Odin will fail on flashing a non-chinese ROM" - So, supposing I am able to root and install TWRP or CWM Rom Manager, even then, flashing a mostly-stock ROM based on the European stock T705, it's definitively going to lose 3G/LTE ?
Thanks

Status update:
Got device rooted ( used Odin 3.07 in Virtualbox)
Got Busybox installed
Got TWRP Backup *app* installed - not yet been able to install backup Recovery menu.
Where I'm currently at:
Trying to get TWRP recovery working, to make a backup of my current stock ROM.
Problem: Rebooting into recovery menu does NOT yield any menu options for backup/recovery. It seems to be the stock Android 4.4 recovery menu: NO ability to create a backup. (That I can find.)
Anybody got some idea what to do here?

Even changing the kernel broke LTE and 3G on mine

Succes!
Thank you very much for the post! I had the same problem.
Before using the ROM you indicated in your post: (pibach's one)
1.I used Odin to root my device.
2.I downloaded the tar file of the TWRP (for this device )
3.Installed the TWRP using Odin
4.Copied the ROM onto device(I didn't use a SD card)
5.I downloaded ROM manager app
and installed it onto the device and used it to reboot in recovery mode(using Reboot into Recovery)
6. In the recovery mode I went to Install and found the zip with the ROM and installed it without any problems
When the system started I was unhappy because there were the same Icons from the Chinese software . But when I opened the menu Play Store was there :good::fingers-crossed:

OK so hopefully nobody had already read my post but none of this was necessary for me as I am still living in China (therefore there's no need to worry about messing up the radio). All that was necessary was to download the "App Search" application that is popular here in China and then search for "Google Play" Store which was still in the mainland China database. In order to set up the account the rest of the way, I used my VPN to connect to the Google network and voila!
The reason it seems tricky at first is because the government blocks a lot of services that are not China-based from reaching China and it also blocks China-based services from going leaving China. So a VPN is an absolute must for using Google...but to find Google apps is a piece of cake.
But if you intend to take the tablet outside of Asia then rooting is most likely still necessary if you want to use LTE/3G.

I am in the USA. USA Tablets do not have LTE phones as the carriers want you to buy expensive data packages.
the way around this is to buy the SM-T705C which has the correct transceiver radio in it.

Current Problems:
1. I can not get any Windows 7 or Win 8.1 machine to recognize the SM-T705C at all using the stock USB cable. , Need Help. I need to be able to access & transfer files.
2. Screen shuts off even when connected to USB cable. All I can do is control the delay. Very annoying
My goal is to unlock and then root the phone so that I can dual boot the original OS and any other Android OS.

i need the t805C chinese stock rom to fix my 'baseband unknown' and no 4g/LTe/signal issue.
please??

Doesn't the Hong Kong firmware work on the Chinese version?

Hi
I have the same problem, i want to change to european rom, but can´t, nobody succes?
Thanks

Please identify my SM-T705 build!!!

Hi there,
I have the Samsung Galaxy Tab S 8.4 LTE version, which I purchased through Ebay - I believe it came from Asia somewhere as it showed up with an international adapter for the power supply. It was sold as a "Verizon" model - I ditched that sim card and have been using it with Bell Mobility in Canada.
Recently, I tried to update my firmware using the latest version of Samsung Kies and I'm running Windows 10 latest version. For some reason Kies needs to reinstall the USB driver before performing the update to the firmware and this causes Windows 10 to crash without fail. (This is also happening to my Note 3 - Samsung informs me Kies is not compatible with Windows 10 although it seems to work for everything else - just not the update). Kies doesn't seem to care that I already have the latest drivers installed.
I can't update via the tablet because my device has been "modified" - rooted.
Finally I went to Sammobile for the firmware, however I can't find any US firmware for a compatible carrier under SM-T705. I am debating flashing the Bell Canada firmware, but the model is listed as SM-T705W. In case this is not ok and I need to revert to the original, I'm hoping someone can help me identify my build? The samsung agent offered to identify it but once she discovered it was from outside Canada she said she had no information. So much for Samsung International!
Please help! I'm having battery issues and I'm hoping updated firmware will help, plus I would like to have the latest version of Android. Thanks!

If you're in Canada then just flash the Canadian firmware.

Hi there, forgive me for being thick, but how do you tell it's Cellular south, and what do you mean by region XAR? I'm sure that the fellow I bought this unit from flashed US firmware, however I can't find it on the Sammobile site - in fact I can't find any US carrier firmware listed for this model.
As mentioned above, I did find Bell mobility (Canada) firmware listed for the SM-T705W but nothing for the SM-T705.

You have root so install twrp from the development section and do a full back up of your current system.
You can then restore as you please.
Seems no US firmware for the t705.

LOL... ok now I have another problem. I had already downloaded the Bell mobility file from Sammobile and hadn't seen this response - in the meantime I hooked up with Odin and my download failed twice - I don't get it. I just did my Note 3 10 minutes ago without any issues. Rebooted device and odin between both attempts.
Thoughts?

Don't flash anything until you make that full backup with TWRP, trust me it will save a massive headache should you need it.
Download Flashfire from the link below then set your date back to August, run Flashfire then load up the firmware, select the Flash firmware package option.
From the partitions list select system.img and boot.img only.
Under the reboot options select download mode then hit the flash button.
Once it has flashed and booted to download mode you will need to flash a lollipop bootloader (assuming you are flashing lollipop?)
You will find them in the bootloader thread.
After that just reboot the tablet, it will take about ten minutes for it to fully boot.

Uh... ok you lost me early on. I downloaded the file - how do I install it? I remember using the TWRP thing several phones back when I was messing with custom ROMs. I had a problem with recovery and since then have never gone this route - I've been happy with stock rom and root - installed using Odin... sortof the KISS principle.
I can try TWRP, but could you dumb down the instructions a bit - as I mentioned, I'm a bit thick - particularly with some of the terminology! LOL
This is the file I downloaded - yes, Lollipop - I don't understand why I have the Odin Fail - google isn't helping me understand either. I have root, USB debugging is enabled and I followed the same steps as with my Note 3 - the message said write fail.
http://www.sammobile.com/firmwares/download/52301/T705WVLU2BOE4_T705WOYA2BOE4_BMC/ Is this what you mean by bootloader?

Ok but those "bootloaders" are custom ROMS are they not? And I don't see my device on the TWRP site - I have the LTE version, it only shows Wifi.
Really all I want to install the Bell stock firmware (assuming it is indeed compatible - SM-T705 vs SM-T75W) I linked to from the Sammobile site and then do Chainfire's auto-root.
Why isn't Odin writing the firmware to my device? I've never had this issue before and I don't see what I might have done differently with this device - it's the first time I've tried to update it, but I had no trouble rooting it with the chainfire auto-root.

No they are bootloaders they are required to boot the firmware , roms are the os.
Odin won't flash because certain devices will refuse to flash another regions firmware.
My advice to you is to flash the lollipop bootloader first, to make sure it will flash then flash the firmware with flashfire.
Obviously make the twrp backup first.

Ok I flashed the bootloader, and then I tried to flash the firmware with Odin again but it still won't do it - write fail again. I've never used flashfire - windows 10 won't open it...
UDATE: Ok I read to transfer the file to the download folder on the tablet, and then install on tablet. So I did that, but when I click on the icon it doesn't run. How the heck do I use this to install the firmware update?

Figured out the date bit, ran Flashfire.... problems during the install - got stuck in boot loop - tried a factory reset - that didn't work... stuck in loop. I think I'm bricked....
Left the default settings in place - very little in the way of instructions - read the bit about not trying to write over protected settings...
And got this:

You're not bricked as long as the tablet starts up and you can boot to Download mode.
I've seen that error with corrupt downloads so not sure why you're getting it.
Reboot to download mode. Just hold POWER + HOME + VOL DOWN until the device restarts and boots to download mode.
Doesn't matter if it's boot looping.
Reflash TWRP and restore the backup you made earlier. You will be back to where you started.
At this point I think the best option is to flash a custom lollipop rom.
There is a very good one I use on my t805 which is practically stock with a bit of bloatware removed.
Its in the development section called sweetrom.
At least one positive is that you were able to flash the lollipop bootloader, so upgrade is not impossible.

I'm definitely able to get to download mode - I was surprised that the factory recovery mode didn't work. I'm wondering if the file from sammobile is corrupted - I used the same file with Flashfire - now I think Odin was trying to save me. I'm downloading the same file again fresh, and it looks like Telus and possibly the other Canadian variants are the same - unless it's the same corrupted file.
I just hope the problem isn't because my phone identifies itself as a straight SM-T705. That is why I asked about that point earlier. There are plenty of straight 1705 options available - just don't know which country would be compatible - particularly for the modem.
I didn't understand how to use TWRP and I've had problems with it in the past (recovery) when I did figure out how to use it and was messing with custom ROMS a couple of years ago. I would really like to get myself back in order with a proper stock ROM and root. This tablet belongs in my car and right now I just want it to work properly - I'm using Torque to resolve some ongoing engine issues and it will suck if I have to go back to using the small screen on my Note 3.
If there is any way to figure out which of those countries for the 705 are compatible with Canadian carriers, in case this Bell firmware is defunct, that would be appreciated.
As well, is that bootloader going to cause any problems with stock firmware? I've already flashed it - does stock firmware come with bootloaders included?

OK before I go any further with this I need you to install twrp and make that back up. Twrp is now very stable.
Twrp will back up some very important partitions namely the Efs and modem. Don't take this warning lightly. The amount of people that have soft bricked their device because they didn't do this.
Boot into twrp then simply select the backup option and make sure the partitions on the left are ticked particularly boot,
Efs and modem.
Now as regards which firmware.
I would forget about installing the Canadian firmware.
It looks like this firmware will only install specifically on a Canadian device.
It doesn't really matter which firmware from which region you install as they are pretty much all the same except for the carrier ones which just add more bloat and some csc specific stuff.
Just go for an international rom. You've already flashed a bootloader from one of these roms so that proves you can flash.
Use odin to flash.
If you have connection issues afterwards then all you need do is restore your modem backup with TWRP.
That's why it's important you do this.
Follow these instructions and we will get you up and running.

Whole again!
Whole again!
For the record, I read elsewhere that it is NOT recommended to flash other letter variants of a model. In the meantime I downloaded all four Sammobile Canadian Carrier files and they appear to be the exact same file and all install attempts failed For anyone else with an actual SM-705W I read in this thread: http://forum.xda-developers.com/galaxy-tab-s/general/t705-lollipop-t3099945 a fellow Canadian was having a problem with those same files. Dunno what happened with him in the end, however I tried one more W file I found elsewhere that appeared to be different but it failed as well.
Based on the comments in the above thread, I flashed the Hong Kong variant for the SM-705 from Sammobile - apparently it was the first firmware widely available and users from several countries posted they had used it successfully. So far it seems to be working ok - after flashing it, I did a factory reset on the device as was also recommended in the above thread. Sure hope the battery life will be better than before - love this tablet but I've never seen a device drain so rapidly! CF-Auto Root restored!
As a side note my Ebay seller did reply to my origins query and was helpful once he realized I wasn't complaining about the device and wanting to return it... LOL. Apparently my unit originated in Singapore and arrived with that firmware along with a Verizon SIM which I never tested. As long as the OS is smooth, and the modem compatible, and unless someone advises a better country variant, I guess I'll stick with this one.
Now just need to get Torque reconfigured!

Trouble installing stock firmware on samsung galaxy a5 2017 sm-a520f

I was trying to root my samsung galaxy a5 2017 with TWRP and I accidentally deleted system data. Then, I tried rebooting the phone and it got stuck in a bootloop. To fix this problem I tried flashing stock 8.0 firmware from sammobile via odin and I got this error:
Sw rev. Check fail. Device: 6, binary 5. I think that this means I have to flash the latest stock firmware but there isn't a newer one.
After that, I tried to use my phone by flashing a custom rom (Lineage 15.1) and I discovered that I have no imei,no baseband and no ip adress. I have installed many custom roms but the issue is still there. I am trying to get my phone to work with stock firmware and fix the IMEI issue but odin wont let me flash because of that error. I would appreciate if anyone could help. Thanks.

Flash a firmware version that contains S6 or U6 in the middle, it won't work with U5/S5! Not the Samsung phone S5 or S6, but rather, the firmware version.
For cellular, change the modem firmware, or backup and wipe /data/. /data/data/?.
Unless the efs was wiped (probably not if the baseband version isn't there, load a backup then, only if the efs was wiped don't restore it otherwise, and it must not be a backup created with an older twrp, view the recovery log in the backup folder)

Listen to me, it happened to me 2 days ago, and I came to the conclusion that I was not flash the latest firmware. You need to flash the same firmware with the same bootloader or more recent, the error you receive is because you are flashing an older version of bootloader. Do one thing, type the code *#1234# on the phone keypad
mark the code that gives you on 'AP and look it on Sammobile at https://www.sammobile.com/firmwares/galaxy-a5/SM-A520F/ITV/ select your language and look for the firmware with your own code . You will see that odin flash it.

Samsung A520F Custom Binary Error
Hello please I have been trying to reload my Samsung A520F firmware for a couple of weeks
It all started with the phone trying to update (over WIFI) and somewhere along the line files must have gotten corrupted
This led to the phone constantly restart and shutting down applications
I decided to just download the firmware and use Odin to reload. This, unfortunately, didn't go so well as now the phone isn't starting up anymore but can still get to download mode.
PDA firmware is A520FXXUACSE6
Region is EUR
Network is OPEN
every time I use this firmware I get the error
" Custom binary (BOOT) Blocked by FRP Lock
Please note currently at the moment phone refuses to boot up I read about removing OEM lock and don't know if this is the problem.
Please could you help out

Obviously you are frp locked. But I didn't think that blocked from flashing official.

Error when installing stock OS: SW REV. CHECK FAIL(BOOTLOADER) DEVICE: 7. BINARY: 6

Recently I rooted my S9 and installed Lineage OS but I didnt like it and decided to swap back to the stock OS. I used Frija to get the .tar.md5 files for Odin but once I select all the files and hit start the log in Odin loads up to system.img then stops and I get the SW REV. CHECK FAIL(BOOTLOADER) DEVICE: 7. BINARY: 6 error on my phone. Any idea on how to fix this? I'd really appreciate some help as I'm going to be travelling soon and I need my phone for it and I'd prefer not to use Lineage OS. Thanks in advance.

Do you have an At&t branded phone? SM-G960U?
I am having a very similar problem. A customer came in and was having issues with device. I told them to back up, wipe, and update device. That didn't work so I tried a full flash with ODIN. Now I can't get the phone to boot at all and it says, "Secure Check Fail : Modem" and "Unauthorized software visit nearest AT&T blah, blah,..)
I think it is because AT&T has pushed out the latest update(OCT. 18th), but the Odin files are not out yet. According to:
https://www.att.com/devicehowto/tutorial.html#!/stepbystep/id/stepbystep_KM1253489?make=Samsung&model=SamsungG965U
G960USQS7CSI5 is the latest FW. If you google it, there are only four results.

Yep, the problem was the phone was on the latest FW. Newer firmware was just uploaded a few days ago.
I flashed:
G960USQU7CSJ2_G960UOYN7CSJ2_CHA
and now I'm booting again.
Your problem is that your firmware is too old. Basically, you are trying to downgrade your FW. The phone is basically saying, "Hey, I have bootloader 7, I won't let you install something lower than that."

^^^^ this ^^^^
the Odin error is telling you that youre trying to flash a revision of the bootloader than was last installed on the phone. to to sammobile.com/fimrwares and get the one with the correct bootloader for your specific phone and flash that.
also download the firmware with the frija tool or samfirm. trust me, its literallt 5x faster than a direct download from the site. The 5 min it takes to get samfirm up and running is worth it, believe me on that.

I may be new to this, But I just Flashed a SM-g960u, That Had Bootloader7 locked on it, When I would go into download mode I would see FRP ON, and this Firmware G960USQU7CSK6. So I downloaded a Combination Firmware file. Used Odin Patched, Flashed it there is a guide out there. Restarted into the Settings, Turned on Developer mode, USB Debugging, and Was able to change OEM-Software install. Then I was able to load this phone after, with G960USQS7CSI5 with ease My first flash and I had to bypass a FRP and a Bootloader lock. Now I should be able to flash this to the U1 version unlocked and be good! If you need any help I did just do this last night I can guide you in the right dirrection. Litterally I had no help from here as in asking questions I am pretty savy. So you need to make sure your Version has the "7" in the Same Place. Also after I enabled those things while in the phone before Flashing it I chose the Factory Reset from within, SO it erashed EVERYTHING except Download Mode and the Combination Firm Loaded. Meaning I should have been able to flash to anything I wanted

got no help here? how so? I see you got the info you needed to get the phone back up and running properly via asking about it here.
with regard to the bootloader version of 7 in your case, it is a very known thing that whatever bootloader version youre on, you cant go backwards from.
In either event, im very glad that you got it up and running!!

Ok so first you should post I'm your devices threads but that aside. Here's what's up. You can't downgrade the error shown is saying your device is on a bit 7 binary. Your trying to flash a bit 3 binary which isn't even 2 you need to find your respective firmware in a bit 7 or higher.

Like 99.9%. That's what that error is. The bootloader is blocking downgrade

yes, if you get a firmware version matching the one last installed on your device, itll go right thru and boot just fine. Goodlock is finally working on all modules for A10 as well. Maybe we will see more development occur with this shutdown going on. Let us know if you run into any trouble, the error you were getting is totally resolvable!

at the end I give up on it..! my internet 2 slow 4 go downloading & trying rom after rom.! i am from venezuela.

I have S20+ running Android 11 with U7 Binary. I tried downgrading to Androi 10 which has Binary U5. Now I have downloaded the Binary U5 file. But in some video, he is telling that you should download the Binary File with the same number as it is currently installed in your phone, which in my case is U7. So? Am I supposed to download U7 Combination Binary file and flash it in order to downgrade to Android 10
OR
Should I flash the U5 Combination File and flash the Android 10 AP, CSC, BL, HOME ???

Someone has Combination file to G960F with bootloader SF (Version 15)?
