I'm rooted, stock ROM (locked bootloader..for now)
The other day, I couldn't connect to wifi, it just hangs on 'obtaining IP address', tried different routers, restarting phone/router/modem, I even did a factory reset, which didn't help.
What I think caused it, is when I installed this:
https://play.google.com/store/apps/details?id=com.mgranja.iptables
(it claims to install iptables, but the version is has is out of date, etc.) which wasn't a great idea, I know.
my question is, how do I fix it? I'm thinking it corrupted something in the OS, which means I can just install a custom ROM, or go back to stock (somehow) but I don't want to unlock the bootloader unless I absolutely have to (giving this phone to a friend, soon)

Hi, I'm having a curious problem with my S3 and I've been unable to solve it. I watched the "noob" video and tried searching these forums as well as a google search with various combinations of the wording for my problem. Nothing matching my issue turned up, I hope I didn't miss anything.
I recently bought a S3 second hand (yes, i know, i should have known better). It was rooted and running some kind of custom ROM when I first turned it on, but I was willing to deal with it until I double checked the procedure for getting it back to stock and starting again myself (nothing against the original rooting and flashing, just like to know exactly what I'm running).
When I purchased the phone I obviously checked that all of the main things worked - calling, texts, mobile data, wi-fi etc. I get home and connect to my home wi-fi and start checking things out and setting stuff up. The phone randomly rebooted. I carry on after the reboot and about 10 mins later, another restart.
To cut a long story short, there is something wrong with the wi-fi. If I turn off wi-fi in the settings menu and reboot, everything works great. No crashes, no reboots. If however I enable the wi-fi about 50% of the time it will crash while wi-fi is activating. The other 50% of the time, it will crash as it goes into the screen lock (either via timeout or pressing the button).
I've re-flashed to it's stock version of Android (using the 'Samsung GS3 Toolkit and Odin), same problem. Anyone got any ideas?
Thanks in advance
You can try updating the modem and RIL to the right version for your country, search in general forum. If it still reboots then try with another wifi source - I've seen some routers cause problems on client machines.
If you do a factory reset when you flash the modem, plus you have the latest stock ROM on board, then any remaining problems are probably hardware.
Test it fully after the factory reset, before you add any apps etc.

After much experimentation and flashing of various files to my phone I have further narrowed the problem. I've still not solved it, but getting closer I feel.
After a clean ROM flash it works like a charm regardless of how much i use the wifi etc. It's only after the first reboot that the trouble starts. It will begin randomly restarting. If I perform a factory reset from recovery mode, it works again, but starts resetting again after a reboot.
Any ideas?

Okay. I got this phone off amazon as an unlocked phone. I has been working fine for several months, but it is short on internal memory because the internal memory it is almost completely consumed by bloatware. I rooted it using Super One Click 2.2 so I could delete some bloatware. After rooting I could not connect to my wifi (which I always have been able to connect to with this phone without issue). All I get is "Acquiring IP Address". Here is what I have tried so far that has not worked.
1. Factory Reset (4 times).
2. Master Hard Reset with wipe.
3. Router reboot and unplugging it.
4. Clearing Router mac address table.
5. Unrooting phone and factory reset.
6. Custom "ADD WIFI Network"
7. Using "Static IP" workaround.
8. Changed Router SSID and network security to OPEN (no security).
None of the above have worked. I think I know what might have caused the problem. I performed the root with the Super One Click app. During the rooting process it came up and said, "Busybox not installed. Would you like to install it." I figured it was needed for rooting so I let it install Busybox. After doing some searching on connection issues after rooting, I found other people blaming busybox for the problem. I have no idea what Busybox is or if it is the cause. I assumed that if I did a master hard reset that it would fix the phone, but it remained rooted even after the master hard reset, which tells me that some of the things that rooting the phone did cannot be undone by a master hard reset. I used Super One Click to unroot the phone, but the problem still persist.
I believe the only way to fix this problem is to flash the phone with the original rom (or other good rom). I need a walk through on how to do this and a source for the rom. Can anyone help me? Thanks
Good day,
I have a samsung galaxy s3 i9305 LTE and I have been using this device without problems for around 2 years now. It runs on Jellybean 4.3 baseband version i9305zhucnb1. It has been running on this firmware for a couple months now ever since it has been rolled out. The problem is, the WIFI suddenly stopped working. Never had this problem before and I actually never had any problems with this device ever. Whenever I turn on WIFI, it detects my home networks and other networks wherever I go but whenever I try to connect, it just shows saved secured, and sometimes authentication error after a couple of attempts. I have other WIFI devices at home and all are working perfectly. I tried forgetting the networks and I am positive that the WIFI password is correct. I tried to restore the device to facroty settings hoping that it would work. I tried accessing my router and I'm sure my device isn;t blocked. I even configured my routers to only accept the mac address of my device and block all others but still wouldn't connect. I tried rooting my device via odin but my device blocks root access and shows the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". I tried rooting it to try flashing custom roms. I also tried dialling *#0011# to configure my wifi but it still does not work. I don't think that the problem is my firmware because I had it for months and it didn't update before the issue occured. I was also about to try downgrading it to an ICS stock rom since I can't root it to try custom ROMs. I've been trying to fix this for days now. Can you guys give me a step by step instruction on how to fix this if it is at all possible? And maybe give me a link where I can download ICS or lower stock ROM's for this device. I think I have to use a TGY firmware, though I don't have an idea what it means. Thanks!
Wifi module
Maybe you've dropped your phone and the WIFI module loosened, and it can't work correctl?

Maybe it's time for factory reset? I know that's the easy solution and most complicated but you should do it from time to time.

Well, i think this may be the time to perform a complete factory reset ! try backing up your data and perform a complete factory reset.
nope
already tried factory reset, already flashed stock rom. already reset wireless router and the router is a non-issue because i tried on several networks.

help
i decided to have it checked by a local technician and according to them, this was still a software issue. i dont know what to do anymore. they insisted that i should just keep flashing stock roms to fix these. already tried flashing the 4.3 tgy jellybean stock rom so i was thinking of flashing other version stocks. can anyone give e a good link where i can download tgy stock roms 4.1.2 or even ICS stock roms. I also am having problems with rooting the device. it gives me error message "an application attempted to access system on your device without authorization. this attempt has been blocked." after flashing autoroot in odin. my knox is not installed. thanks.

dont know
the first time i brought this to them is when i attempted to flash an incompatible firmware. they also did not fix it. they said they dont have any available stock rom for i9305 and told me to download and flash one. mayba im just gonna have to look for a different technician when i have free time. so for the mean time, im trying to look for other fixes. btw, i tried downloading a tgy 4.1.2 stock rom and it does not flash successfully. for now i'm thinking of rooting and flashing custom roms. but whenever i flash auto root. it gives me the error message "an application attempted to access system on your device without authorization. this attempt has been blocked.". i tried updating supersu still the same thing. i manually installed root checker and says it does not have root access and it shows the said error message again. what should i do with that? Thanks
So I'm not sure what I did because it's been a while since I messed around with this phone (bought a Honor 8 Pro after that), but I most likely flashed something wrong. So the first weird thing is that apparently my device went from "griffin" to "sheridan", not sure how that's possible. The second thing is that when I flash a stock ROM, I have no wifi (it doesn't detect any network) and in settings it says my IP Address is unavailable. I tried nearly everything. Resetting WiFi settings, rebooting, reflashing stock ROM etc. Nothing seems to work. Help please?
My phone says sheridan too when i boot in bootloader mode. Anyone know whats os this?

Most likely you have flashed incorrect firmware. But this problem is common even with locked/stock devices, possibly could get fixed in the next update. The problem is that there is no way to downgrade firmware (otherwise this can be fixed by flashing 7.0 stock rom including firmware)
Downgrading the Firmware isnt a problem. Downgrading the bootloader and gpt isn't possible. Anyhow, my wifi and BT are broken too and going down to 7.0 and than installing all OTAs won't fix my issue.
Hello all,
I recently rooted an old Samsung Stratosphere in an attempt to turn it into a mobile Kali device, and after rooting it using a custom ROM ("root zImage" that I found via googling and a forum post on rootzwiki) and then performing a factory reset, I now have no wifi or BT, and no MAC address. Attempting to connect to my wireless network results in the phone starting wifi, attempting to scan for a few seconds, then returning an error message of "unable to scan" and turning the wireless radio back off. Also, now the phone tries to activate every time I turn it on. I can bypass the activation by enabling soft keys (I googled that also), but how can I disable the auto-activation?
I installed CWM recovery and did a factory reset, no change. I removed the SIM card (I even tried a different one from another one of these phones I had laying around with a broken screen), no change. Why would the MAC address disappear? Isn't the MAC address tied to the actual hardware?
It's a shame that this perfectly good hardware is so difficult to re-purpose to use as something else. Any assistance is greatly appreciated. I am willing to learn Android development in order to figure this out, but I'm really not sure where to start, and I expect this will take some time to get to a point where I can develop my own ROMs and apps. I have downloaded the Android Studio; where should I start? Thanks.
