So, before I start this, Yes I was a noob. I didnt make a nandroid backup from when I first rooted my phone and everything worked 100%. I didnt read, and I guess its now biting me in the ass.
The past few months Ive been having issues with Wifi, it continuously says "Unable to scan for networks". I did a factory reset about a week and a half ago and for the first time my wifi was able to connect, however it was dropping out every couple minutes. Wouldnt even stay connected to install any market updates.
I figured that it was something with my dying router(Which Ive since replaced) so I flashed in BAMF to see if I could keep my wifi connection with another rom. Ive been using VirusROM(Love it even though its out od date). I wiped and flashed in BAMF, and restarted. When I restarted, I had no wifi again. Since then, Ive been trying out different ROMS and kernels in hopes that I would find something that would fix it. Nothing did.
After this I figured that I would just do another factory reset and go from there, however with all of the times Ive done the factory resets it never actually gets reset. Does it wipe my info? Yes, but it boots back up with all of the portions of whatever ROM I had installed last. Not reset. So now Ive ended up with two problems.
1. I still have no wifi
2. I cant factory reset so that I can figure out what is going on with my wifi.
Ive wiped Cache/Batt Stats/Davlick and done a factory reset literally six times in a row to hopefully clean EVERYTHING OUT to no avail. Any help with this would be greatly appreciated. I hope Im just missing something small because Im still new to android.
Edit: I DO NOT use kernel manager and I dont use ROM manager to flash it in, I flash everything in through recovery.

I'm sure there's an RUU out there that will take your phone back to stock but I honestly doubt that's the issue here. What radio version are you using? Have you tried flashing different radios to see if that would fix it. You can find a list here http://forum.xda-developers.com/showthread.php?t=1045081. Also what ROM are you currently on?
When you install a ROM, it modifies the /system directory which is responsible for everything, how the rom looks, included apps, drivers etc.
When you do a factory reset, I'm guessing through recovery, it is only clearing the /data and /cache partitions.
You will have to flash a stock RUU to get it to truly go back to the day you got it.
Here are instructions on how to return to stock:

The ROM Ive been on hasnt mattered. Ive jumped through BAMF, the new Cubed Rom, the Deodexed stock debloat and Virus' Airborne(which is my daily driver). Ive done the different radios. I was on the v2 leaked for a while, then I switched to the new 3g and old 4g to see if its worked but it hasnt. I may have to try out the original one and see if that works, but I havent had wifi since before I flashed in the leaked radio when it came out.

Gotcha. Trying this now. I will make sure to make a nandroid this time if it works. lol.
@isdnmatt: Thanks, that got rid of my recovery problem
Still having wifi issue though. 100% out of the box stock and I get the "Unable to scan for networks
**** me, I should have read that before I did it. Now I have to reroot. Goddamnit.
Have had the same problem with WiFi before and after ADB root. It will sometimes forget both my home and work networks. I've found the problem usually occurs when I'm connected then move put of range. A reboot fixes the problem sometimes. Other times I have to re-enter my settings. I'm still on the stock Rom, nothing custom.

Thats a separate issue than what Im having. Im not having issues with it forgetting my networks. I cant scan for networks.
I am thinking of downgrading the radio.
EDIT: after LOTS of research here, I upgraded to MR2 and Gingervitis. All of my WiFi issues are gone.

I'm having probelms after flashing the supra ROM for the second time. It won't let me post on the thread so I don't know where else to post. It all worked perfect the first time, but now after installing about half my apps it won't install anymore because it says there's no room even though I have 603 MB free. Any idea on how to fix this? It worked fine the first time, I switched to another ROM and wanted to switch back, and then I wiped everything and then reinstalled. Tried twice but same problem. Any help would be appreciated.
Have you tried a full wipe before reinstalling?? If you think that you may want to go back to a rom you should do a nand backup before installing the new rom that way all you have to do is restore the nand.
Yeah I did a full wipe
This happened to me too, on the first install. I just flashed a different ROM
Did it work ok when you flashed it back to supra?
I flashed back to Chogardjr3D and it worked fine. I just tried SteelROM, and it did the same thing. I would love to find out why this is happening. Makes no sense to me
me neither
This was happening to me on every ROM I flashed. I think it has something to do with Google syncing back apps after a clean install. I disabled the Google backup and restore and now all seems to be fine. Again, not sure this is the exact problem. Could just be coincidence.

I've tried it all folks. New kernels, factory reset, different radios, different ROMs. Every-thing. The WiFi will turn on for a quick second and I will get an error message "Unable to scan for networks" and then the Wifi will just turn on and off on and off over and over again. I've even deleted the files in the data/dhcp and data/wifi folders. Rebooted, still same issue. I've deleted the files and flashed a kernel and rebooted, still same issue.
Of course I am still in contract and will have to purchase a new phone outright from Verizon if I can't get this issue resolved......
I don't know what else to do here.....
Did you try formatting data and system before installing a new rom from recovery? If that doesn't work i would say its a hardware issue. You're not restoring system data with any backup programs are you?

I've wiped pretty much everything known to man on the phone. The ROM installs are all "fresh" I haven't tried to install any APPS on the phone. Just wipe everything, factory reset / Dalvik Cache, all of it... install fresh ROM. Try to turn on Wifi, phone boot loops. No matter what ROM I install, still same issue with Wifi / boot looping.
Well guess we can close this out. I went out and paid full boat for a Samsung Nexus since I couldn't fix this issue.
I'd like to reopen this topic. I had been running Bamf Forever 1.10, but last night I decided to try another ROM because it's been running really slow for some reason.
Did a wipe (factory reset, Dalvik cache) and installed Thunderstick. Now WiFi is broken -- the exact same problem as described in the original post. I tried flashing a new kernel and new radios, and cannot get WiFi to work.
Does anyone have any suggestions? Will flashing back to stock ROM/unrooting help?
Thanks!
@ajoesq I had the same problem when i installed thunderstick thru boot manager. My wifi stopped and I could get it going on my phone rom. So i booted back into thunderstick and wifi was working. Booted back to hte phone rom then into recovery and then i flashed my phone rom again without wiping or anything (Thunbershed V1.2) and it worked fine. wifi started agian.

Run a logcat when you try to turn wifi on. Put the output on pastebin.com and post the link. This might tell us what the problem is.
I'd make sure that the radio(s) were at least at the minimum of what the ROM called for.

My pocket felt hot, so I pulled out my phone and saw that it kept rebooting itself. It just shows the initial Samsung splash for maybe a second or two, then loops again. I can get into Recovery and Download modes fine. I tried wiping the cache, factory reset, restoring a cwm backup. No luck so far. I've been using the CM9 rom for months. I haven't flashed or changed anything in months, I haven't even installed new apps in a while. Before this happened, it said I had no signal, so I had to restore my EFS(which I've had to do several times since I got the phone, mostly when I was switching back and forth from CM9 and stock to see which I prefer). After going into and out of airplane mode to reset the antenna, the signal and all worked fine. I let the phone cool down to make sure it wasn't just rebooting due to heat, but that didn't change anything. I've been searching here and google for anyone else with an identical issue, but I've failed so far. Everyone else seems to get to the home screen or just having random reboots during use.
Just to clarify, my question is: How can I fix my phone? Is there any other information I can give that would help?
I have the international i9300. I also tried removing the SD card and SIM card, since one thread concerning a different kind of rebooting issue reported success with that. Nope.
Try to reflash a stock rom on Odin
Is that different from restoring the original rom with CWM? I did that already. I don't have or know how to use Odin, but I'll download it and figure it out if that's the next step.
Solution?
Ok, I never didn't have to figure out Odin. I fixed it by wiping dalvik, factory resetting, restoring the stock rom, wiping it all again, rebooting into stock(it worked), then restoring back to the backup I made after the crash. Some of these steps might not be crucial, but at worst you waste a few minutes to make sure it works right again. Hopefully it'll help others with similar problems.
Hi guys,
I wonder if someone can help me with this... really annoying problem!
I was checking out various roms i downloaded here, started with 4.0 aokp which was great, then gave cyanogen 4.2 a try, but then i wanted to go back to Aokp 4.0 cause it seemed to run faster
Now first thing, i couldnt get rid of cyanogen (no offense intended) cause when i wiped all data, cache and dalvik it just took aokp a few seconds to install from CWM recov, that doesnt seem right, right?
Then installed GAPPS, but still it ran on Cyanogen
So, i did a NANDROID backup, which made my phone like before i started with all this..
THIS IS WHERE IT WENT WRONG?
now it just wont read my simcard
i tried my sim in my old phone and that works fine, so the problem is in my phone somehow
is it something about the radio settings specific to my phone and network?
how can i change these settings and are they specific for my provider?
you guys always helped me out so i hope you know what i mean..

I've exactly the same problem.
Are your wifi and BT still OK ?
Is your IMEI (*#06#) still the same as under the battery ?
Was your phone locked ? Did you buy it with a SIM ?
My problem appeared after flashing several different modems/RILS : I got no error warning anywhere, but after reboot, I completely lost my netwerk connection. (no voice calls , no mobile data)
At first I thought a bad RIL driver, so I restored my Nandroid backup from the day before (after wipe cache/wipe dalvik/format system), but still no connection with the netwerk. and can't even make voice calls.
Then I was in panic !
After this I did a complete factory reset, and wiped/formatted cache/dalvik/system/data/SD-card and went in to download mode. After loading a stock ELLA for my region using Odin, still no connection. I was also never asked to enter the PIN-code for my SIM to unlock it.
Damned, this is an embarrassing situation : I can't think of loosing my SG3 for several weeks if I have to send it to Samsung !!
Mu phone is bought without SIM, so it's not SIM-locked.
My Wifi and BT are still OK, my IMEI is also still OK.
Any other ideas, please ?
How do I come in the service mode for the Radio ?
This is the way my netwerk is indicated : a circle with a stripe, much like the famous traffic sign.
Its fixed
So i have no idea how it eventually got fixed but if someone else has this problem, heres what i did:
Full wipe/factory reset blablabla all that
Did Nandroid restore again, put the AOKP ROM and GAPPS back on my phone
Installed ROM which was I9300CEDLI1
Used Odin to install latest CWM, which was already on there, but still
Then booted into CWM and installed .zip of course
This still went suspiciously fast since the very first time it took way longer, that worried me but,
Installed GAPPS again,
Rebooted... IT ASKED FOR MY PIN NUMBER!! hell yes that was what i wanted!
So now it again sees my simcard in there, so now i can make calls end use intnet again!
Still i think it started after the nandroid backup for some reason, or it may have been because of wiping Dalvik Cache?
I have no idea if that even makes sense

Good to hear your problem is fixed !
I'm still not able to make voice calls or enable mobile data : "insert SIM card" is the message I get.
I did already twice a full reset/factory restore and flash a stock ROM using PC Odin, but no avail.
Today I did a restore from my EFS folder using a backup that a had made before the problem appeared, but no avail.
BTW, did you also have the same indication from network status as on my screen-shot ?
Any idea what else I can try ?
I'm getting desperate .....
I'm having the same trouble after doing backup in TWRP when boot up it doesn't recognize the sim card.
I've flash CM10.1 and it only work after i remove the card e put it back on.
Try to see if it something about the simcard.
Regards,
Rui
