Download Odin One Click Downloader, connect your phone to your comp while in download mode, press start on Odin and wait. this will take you back to the OS you bought it from. for example, if you got Ur phone in android eclair or ics or GB or whatever, itll go back to that way. use samsung kies mini to upgrade your phone back

[Q] Need my data connection back

I've bought a Samsung SGH-I717 locked with Rogers that's was working perfectly with my Koodo sim on LTE. Here's what happened. I was doing all right, starting by unlocking my phone (First success!). Rooting my phone (Second success!!). Installed CWR (Third success!!!) Why stopping there? I wanted to install LiquidSmooth JB. So, I've started the installation following every steps to the letter. Restart the phone... Hello? No more phone. Just got a nice brick...:crying: So, as a humble guy, I sent it to an unbricker. Don't plan to brick it again so to pay for the JTAG won't have been cost wise. I got my phone back (less 85$ ) but...with the AT&T rom (4.0.4). My problem is that my data isn't working anymore. The WIFI works fine but I won't see the LTE logo next to the WIFI one and as soon as I close the WIFI, no more data. I've tried the plain reflash from Kies. It worked, for the flash, but didn't resolved my data connection issue. I've turned on every things in the Wireless settings, it's not from there, I'm sure. Packet Data and roaming are checked. So, what can be my problem? Just to be sure, do I have to use AT&T rom from now on? No more canadian stuff? Thanks from a desperate guy...
You can install CWR and flash Canadian ROM. The ROM will be already rooted. That liquidsmooth ROM broke lots of phones. The ROM was actually for an S3.
It's worst now. :crying::crying::crying: Since the phone was unrooted, I want to root it again. I've followed this steps : droidgator.com/root-att-galaxy-note-sgh-i717-running-android-4-0 and now... It will only boot up to the Samsung logo. I can at least access the download mode. I'm so [email protected][email protected]$ tired of this.

Help - Connection problem after upgrading Android 8.0 - Samsung galaxy s7 edge

Hello everyone. I have a samsung galaxy s7 edge (SM G935F) and i recently received the android 8.0.0 from samsung. Downloaded and installed directly via the cellphone.
But after updating i am getting this internet/connection drop issues a lot.
Now a lot of times when im connected in wifi or using the 4g mobile internet, im getting a lot of internet lag/drops. Example: at whatsapp, when i sens a message, the clock appears and only after a little rhe time the message is send.
Example 2: at facebook, somerimes it lags and takes too long to load the content (same happening in instagram). Or at clash of clans, it is showing that symbol of internet issue.
Besides those internet bugs/lags, the android 8.0.0 is ok.
I already did a factory reset yesterday via the phone, and saved the files with smart switch. But the problem persists. I also checked and my wifi internet and my mobile internet are ok.
Does anyone knows how to fix this issue? Is there a newer version of the ROM, maybe? Or if not, is ir possible to downgrade to android 7 again (really wouldnt like this option but....)?
If anyone could help that would be great. But for the record:im really newbie at android stuffs....if you can help, please could you explain step by step?
Thanks everyone

I have the same phone but in my region the OTA 8.0 upgrade didn't arrive yet so I took a french official 8.0 for SM-G935F and installed it. After about one week I can tell it works like a charm and even better than before with the Marshmallow firmware. I don't see a solution with your specific connection problem but I can try to find and bring you the OS that I downloaded and used if you want.

NO, i can't seem to remember where i downloaded the firmware from, but I am sure it wasn't from Sammobile because it take ages to download. But I still have it on my laptop so I'm uploading the .rar on mediafire.
All you have to do:
Get Odin
Get the ROM (extract it separately, you should see the AP, BL, CP, CSC components)
Cause I am a new user on the forum it doesn't allow me to post external links so let's get around that:
type in w w w. mediafire . com /file / tx3676bj71vz17f/G935FXXU2ERD5_G935FOXA2ERD5_BTU.zip (copy paste and remove all the spaces)
Activate USB debugging (google that, you can get it in 30 secs)
press and hold power+home_button+volum_down then press volume_up when it asks you to confirm that you know what you're doing.
Open Odin, you should see that your phone is recognized (in the top left rectangle it shows COM something.
Add the AP, BL, CP and CSC from the folder to Odin by pressing the specific buttons and then selecting them, wait between them if necessary, it will tell you.
Make sure re partition is not ticked in the options tab.
after everytihng is ready, click start and wait some time.
When it is done you should see PASS in green and your phone restarting.\
From there you just have to configure your new OS. Bare in mind that you should know the google acc and password that you had on the phone before, else it will get FRP locked.
Hope this helps, If you have any questions feel free to ask.

LineageOS S3 I9300 no carrier or internet 3g

Hi, ever since i flashing roms on my galaxy s3 LineageOS, HavocOS, OmegaOS, SenseOS, N5/N7 OS etc.. I have noticed that my phone did not have 3g or carrier interface i could not use my sim card internet or phone calls at all.
I can use every rom wifi bluetooth everything is working fine, just this problem only, after searching on forums some say i need to flash baseband for my device which will work.
but sadly my s3 usb ports seem broken cannot be used it's has problem only able to charge but can't use as USB. The only way I can do is flash baseband using App FlashFire or Flashify i think. but i don't know what .zip to flash can anyone tell me how, please help thank you.
