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 Is there a newer version of the ROM, maybe?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.

Hey guys,
I hope someone will know the answer to my problems, I'll try to keep this short. (English is not my first language so excuse me for any mistakes I make).
Around 2 months ago I couldn't connect to my wifi, I tried everything, but eventually I thought the only solution was to factory reset my Samsung Galaxy S2.
That turned out to be a stupid decision. I made a back up of my media files, so those were safe. But the option to make a back up of your contacts using google didn't work, so I lost all my contacts, whatsapp messages and text messages.
Factory resetting my phone was the solution to the wifi problem though, so I was happy with that. And in the mean time I've gotten a lot of my contacts back, so that's not that kind of a big issue to me anymore.
But now I have a new problem. My phone can't update it's firmware anymore. I've tried using the update function from the phone, but it says it can't connect to the server. And using KIES, it says that the phone can't be updated as well. Now it's running on 2.3.5 and I'd really like to get the new OS available. (This is problem #1).
Problem #2 is the fact that in the last few days my battery has been incredibly weak. Normally I could last 1,5 days to 2 days with a fully charged battery, but now it seems to only last about 4-6 hours. The phone seemed to be a lot warmer as well.
I've tried to find a solution for problem #1, and all I could find is that maybe the factory reset changed the settings of which country your phone is from (I'm from the Netherlands), and that this is the reason why I can't update my phone.
In the thread I found they were talking about using #1234# and checking the codes there, but when I use this my phone displays (translated) ''connection problem or wrong MMI-code''. So I can't check if the data changed after the factory reset.
What should I do next?
Thanks in advance.
Hello there mate.
Im not a dev or something but from different cases that i've seen with many GS2 phones i think i can help you ( i hope at least ).
First of all i think you can easily update with odin to the new ICS firmware Samsung has for GS2.( If you use windows 7 run as administirator )
You can find many tutorials on youtube of how to do that.
Remember to back up all of your data before updating because they will be erased.
After installing fresh ICS firmware (official 4.0.3) you will need to do a factory reset.
Now for your second problem i think it might be an app problem which requires power from your CPU and that's why your phone is overheating and the battery is draining that fast.
I would suggest after using an app to kill it via the task manager so it won't run at the background demanding dedication from the system.
If that doesn't work also try re-installing all of your apps.
Hope you find this kinda useful friend and solve your problems.Take care
Thanks for the reply!
But before I upgrade with odin, don't I need to know the codes (representing where your phone is from etc.)?
I've found them under settings. They are:
Baseband: I9100XXKI4
Kernel version: 2.6.35.7-I9100XWKJ3-CL647431 [email protected]#2
Build number:GINGERBREAD.XWKJ3.
And how do I backup all my files? Especially contacts, text messages and whatsapp messages?
No problem ! Im glad that you found my info somehow helpful!
Now as i said earlier im not that kind of expert so giving the current sittuation i don't really know. You should search on the internet for your firmware available for your country and also you can search at sammobile.com then go to firmwares then select the Smartphone option then Android and you should be good to choose the firmware and download it for your region/country. ( Terribly sorry for not giving a link but xda forums are saying that i need more than 10 posts to post a link.
So good luck with that one :good:
I never tried it myself but i've seen that people backup their contacts,texts and apps with KIES so you should give it a try :good:
Either than that,this is all i know and im really sorry if i can't help you any further as im new here too
Alright thanks for the help.
I made a backup of my contacts, whatsapp messages and text messages on my SD card. I'm almost gonna start using Odin. (You don't need a rooted device in order for Odin to work, right?). And I also only got a .tar file from the downloaded package from Sammobile.com, is that all I need?
I'll post the results
Yes Odin will work with unrooted and rooted devices!
I don't know if that's the file, i would do a little search before updating about the files and remember to watch a video on youtube to help you with the process !
Things to remember : If you are on windows vista/7 run Odin as administirator
After installing the firmware do a factory reset / clear cache
Good luck! I hope somebody more experienced than me will help you better than i did . :good:
Haha alright thanks for the help.
I used Odin this afternoon, with succes! I updated to 4.0.3 (only using the .tar file) and after that I factory reset my phone.
Also, I managed to succesfully retain my text/whatsappp messages + contacts, so everything's fine.
I'm going to try out my phone for a couple of days and I'll report if anythings wrong with it.
Really glad that things went in the right direction for you
Just a quick thought now, our Samsung Galaxy S2 will get a new update to 4.0.4 which is reported to be far better than the current one and will be available on the upcoming weeks so be prepared to do another update
But anyway you did a great job! :good:
Hi !
After 2 nights downloading as many firmwares as I could, and reading forum's thread till I fall asleep, i found no answers, so maybe you'll have some experience to share which might help me and my phone.
Well, at least it's no longer really a phone cuz it's impossible to connect to the network; let me explain to you what happened :
I'm a student in china for 2 years; I lost my iphone 3G 2 weeks ago, and after a lot of hesitation I choose to buy a galaxy Ace 2.... In the chineese way : no google play (or at least impossible to install it), impossible to install applications like viber also, and so on.
So i decided to put an other firmware on it and follow tutorials (i was used to those kind of stuff by jailbreaking and unsimlocking my iphone before android's introducing). First i downloaded the uk firmware (O2). the step "SYSTEM" worked well, but it stopped while launching the "battery management" part of the md5 file. When i switched my phone on, there were some cool improvement : google play's working, even youtube is there (youtube is forbidden in china), but no more network : "no sim cards", and disfonctionnement of the plane mode (once you put it on, impossible to come back, even if you switch it off). I made a factory data reset, which put the phone back to the step "no sim card", then the fly mode problem happened again.
So i also tried 2 others firmwares : the singapour one, and on other one called Android 2.3.6 I8160DXLF2 (would like to add the link but i'm a new user so i can't)
those two times, odin worked like this :
hidden : check
kernel : check
modem : FAIL
Now I don't really now what to do, I feel lost.... Do you know what could i do else :
-to complete a firmware upgrading
-to have my phone like it is now (with an occidental firmware including no restriction), but with more "phone skills" ?
Thanks a lot for your help and experience sharing =) ,

up ?
you need a proper firmware

Since you said that you bought your phone the chinese way, there's a possibility that you have a ZLSG1 or any chinese related baseband, you need to download a ZLSG1 firmware or any firmaware for china region.
You can visit my thread here.
Be aware that the chinese/hong kong firmware for Ace 2 have severe problems with scrolling so I suggest that you flash my custom firmware if you want, or you can wait for jelly bean update which would probably released after a few months or next year.
as for the modem.bin part, its kinda weird because you can flash a custom or different modem with any other samsung phones like the S2 or the original Ace. But the Ace 2 or even the Galaxy S Advance, you can't flash a different modem binary or power management binary...
Hi,
This is my first post on xda-developers. You guys are doing a great work. I am a newbie when it comes to android so I would really appreciate if you guys consider than in your replies.
I have a Galaxy S2 international version and I installed official ICS by directly updating the phone from settings using wifi/carrier network to download. First two downloads worked fine (240s MB & less than 20 MB). 3rd update file downloaded successfully (it was 100-150 MB). I installed it and it gave some error during installation about some file missing on SD card. But it completed successfully anyhow
Now the phone works fine except these two problems I found so far
1- Some kind of system information on home screen which wont go away and appears over any wallpaper I choose (screenshot attached)
2- Swipe/patter unlock etc don't work even when I choose them in settings. Phone just unlocks when I press the power button.
Now I know this might have been caused by a corrupt download but please tell me some steps to solve this problem. I want to do this without rooting the device and want to install only an official ROM. Also is there a way to recover it without having to backup everything and resetting the phone ?
Thanks

You have to install the Google Apps as a separate install when dealing with most non stock roms. Surely the guide you were looking at mentioned that...? Weird that you are having issues with Sms as it's rare roms have that trouble. Which messaging app are you using? Your contacts aren't there because you wiped your phone, installed a new operating system, and didn't install the Google apps to resync your account. I'm confused on why you're surprised by that... Kies doesn't work on non stock roms and is a much inferior tool vs Odin. Also, didn't you do a nandroid backup before installing Slim? If so, you could just restore that and you would be back to the previous version in like 10 minutes. If you didn't...well, you weren't looking at the right guides then. I think Slim is 10x better than stock, personally but depending on the phone and version, there can be some minor issues.
I think that Whatsapp doesn't recognize your phone because of the custom DPI. If you set that to stock value, it should work.

- HI, I'm not sure what is wrong with my tablet. I have a Samsung Tab E which was bought in Jan 31 of 2017 Model number SM-
T560NU with the following specs .
Kerner version
3.10.49-12379902
[email protected] # 1
Build Number
NMF26X.T650NUUEU1CQJ3
It will randomly restart itself and boot back up. Once I had it turned of for the night only to find it was turned on when I woke up in the morning. It shuts down randomly for no reason. I have tried the follow:
Wipe Cach
Factory Reset
I didn't install any apps on the tablet and just used a boot logger to see when it crashes.
I don't know what to do with it, I tried contact Samsung for a repair but they only use Fed-ex shipping labels and Fed-ex will not pick it up for me and its over a 1400 km return trip to drop it of at a Fed-ex location, Yes i live in a rural place in Newfoundland Canada. ...
Any help on this would be great,
Is there any apps that track and show you what causes the crashes?
TIA
Hi , if you have a pc with internet search on the internet stock firmware for your device and your region , download Odin , put your phone in Download mode and flash it .

Hi ..
I have tried this method already, I installed the (T560NUUEU1CQJ3) version of Android 7.1.1 and the problem still came back. Now, knock on wood I flashed it with Odin to android 6.1.1 (T560NUUEU1BPF5) so far it has gone 18 hours with out crashing, i'll provide and update on how long it stays running.
If it is a firmware issue with samsung it really sucks as I would love to be running Android 7.1.1
Thanks for you input, much appreciated
Hi once again , did you tried with 4 file repair firmware for your device maybe that will solve your problem . Search over the internet if is available for your device and your region.
Hi. What's the advantage of this over Odin? It seems to be the same process. What am I missing?
Update. 6.0.1 ran for 36 hours and did not crashnthe tablet. I then updates to the newest 7.1.1 and so far after 12 hours no crashes.
