[Q] WiFi suddenly stopped working - Thunderbolt Q&A, Help & Troubleshooting

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.

[Q]Wifi issue still present factory reset fixed.

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.

[Q] Liquid Thunderbred v2.3 android.phone FC

I've tried the Liquid Thunderbred 2.2 and 2.3 and I can't get either if them to work. I get a constant android.phone force close. Using 627r and I do a full wipe procedure. Any ideas? I've heard good things about this rom and would like to try it out.
Did you try format system in recovery. Do after you wipe data and cache.Then load ROM.
Good luck it is nice ROM
Sent from my HTC ThunderBolt using XDA App
i am having this same issue regardless of what rom I use. It fc and then it acts like it has lost the 3g signal. I am going mad here with trying to figure out what is causing it to crash when I try calling. It isnt consistent either as some numbers arent crashing. any ideas?
I had issues with mine until I did a full wipe, loaded the radio first (MR2.5) followed by installing LTBv2.3. Make sure the back is on too. I kept wondering why I only had a x1.5 connection for a couple hours, thought I had screwed up installing the radio. Eventually I popped on the backing and it was fine.
A lot of what your experiencing is either a radio issue or a full wipe issue,,, I wipe data, cache, and dalvick cache at least twice and then load whatever radio that the rom suggests and when the rom loads up give it time to normalize, dont rush it. Be careful reformatting anything in cwm it will erase data on your SD card.

[Q] Wifi not working on rezound after tapped rom installed

Hello All,
I'm not to this forum. I'm having a very strange issue. I had unlocked and flashed a scotts clean rom to my phone. This rom worked fine. It was the cleanrom standard 4.4. Everything worked fine, but I wanted to try something without sense. So I followed the instructions and ran scott's wipe program that wipes 5 times over. Then I did a wipe on the device. From there it got stuck in a loop where I would boot it into the hboot and it would try to load that weird PH89IMG file and then reboot and do the same thing.
Believe it or not I resolved this by removing the SD card then booting to recovery then slightly lifting the battery and inserting the sd card in and mounting so that I could load another rom after mounting it. Just to be safe I did perform one more wipe. I loaded the CLEANrom tapped edition. It installed and booted up just fine, only one problem. I cannot turn the wifi on.
So I cleared the cache and Dalvik cache, rebooted. still no wifi. It sits on turning on. The wifi mac address is obviously unavailable. It went to an error evetnaully, but there was no detail in it other than the word ERROR. I tried reloading the ICS kernel as well, still nothing. I didn't see anything in the forum on this issue, so I am not sure why it's isolated to my device. can you help me?
Thanks.
I know your tired of wiping and flashing but this has happened to me before on a previous Clean Rom version. Wipe then reinstall ROM. **Caution** Before you boot to Rom, boot to recovery and flash the kernel that came with the Rom. That cleared up my broken wifi. Also beware that if the Clean Rom tapped edition uses a different base ie. 3.14.605.05 or 3.14.605.10. then you have to flash the Stock Rooted RUU of 3.14.605.05 or 3.14.605.10 and then wipe and install ROM. link to stock RUU:
http://forum.xda-developers.com/showthread.php?t=1642217
I have had this issue with a couple newer ICS ROMS I have tried and it all seems to come down to reflashing the Kernel. Even after updating Nils' Roms to newer versions my rezound would load up fine and everything worked except wifi. If I went back into recovery and reflash the kernel wifi would be back to normal again. Make sure you have the correct kernel designated for that ROM as I have noticed some Kernels need to be redownloaded and reinstalled seperately. Good Luck
Hello,
I am having the same problem and I am on Rezound Pure GSM sense 3.6 rom.....I am confused whether to flash the wifi modules for the new kernel from the above link....I don't wanna take any risks as I finally got my GSM working on atnt.
Thanks!!

Stuck on boot screen and have tried many, many times...

The gist of my problem: Earlier today I successfully installed the latest CM9 from Joker (.0.7.0.0). Unfortunately, all wireless services other than WIFI were down (including SMS and telephone), and on start the phone produced an error about the com.android.phone force closing (or some such). I figured I had screwed something up, so I reflashed the clean stock firmware.
Since then (roughly 12 hours ago), I've been getting the stuck on the boot screen whenever I try flashing CM9. Relevant details follow:
Logcat doesn't help -- it tosses an error about the shell directory or file not being found (the exact error message escapes me, but I can reproduce it if need be).
I've tried formatting cache, data, and system, followed by a wipe (or two) on several occasions.
I've also tried flashing various versions of CM9 -- specifically .0.7.0.0 and .3.1. Both give the same result. I've also tried whatever version is in the KitchenSink v2.11 installer. Same result.
My CMW version is the 5.0.2.8. I installed it through RomManager (as opposed to the command prompt on Windows, which I did the first time when it quasi-worked). I've read that using v2 fixes this issue, but I can't find a live copy anywhere, so I haven't been able to try it.
Rather than going for a completely new install every time I bork something, I made a backup just after I finished unlocking and rooting the phone. I just restore that backup after each attempt, and it goes back to working fine on the stock Android firmware (3.whatever).
Any ideas? I think I'll try starting completely from scratch again and not using RomManager tomorrow, but if anyone can point out my error before then and save me a lot of -- hopefully not wasted -- effort, it would be fantastic.
Cheers,
Vash

Use this recovery. http://forum.xda-developers.com/showthread.php?t=1218417
Or jokers at http://forum.jokersax.com/discussion/25/joker-recovery-for-the-photon-v3
I use the first link. Works perfect. Once you install the recovery. Wipe everything. Install 0.3.1. Boot into the system. Go back and flash the newest 0.7.0 update with gapps.
Should fix all the issues.

Well, I got .3.1 working. Then tried to install .7 and it crapped itself again. Should I have cleared all the data/caches/etc. between the two?
Edit - I tried it again but this time cleared all the data between installs. It booted, but I got the same 'android.phone failed to start' message.
Edit 2 - Alright, I think I got it. I didn't clear anything between the two installs, but I installed each firmware twice without exiting recovery mode either time. It seems to be working (phone works, at least), although I'm not sure my 3G is working...

Joker's recovery is a zip file you can flash from 5.0.2.8 if you don't feel like hooking up to the computer and using fastboot. But 5.0.2.8 doesn't work right to flash roms.

Yep...already did that and got it to boot just fine. Now I'm struggling with poor reception. I've seen other users (different phones) mention radio upgrades, but I was extremely unfamiliar with the terminology. The phone seems to work okay, but I only get 1x reception for data.
Or were you actually suggesting to repeat the entire process?
Edit - Tried again, still no luck with 3G.

Before doing what i stated did you wipe everything (system, data, cache, dalvik)? Also, you still getting a forceclose upon boot or just crap signal? And are you on sprint or electrify?

well did you have 3g on stock? there's no reason it would go to 1x unless 3g is unavailable. the rom shouldn't cause it to go into 1x.

Yep. Despite popular belief, I'm not a moron =) I'm in the dead center of 3G availability for Sprint in my area, and with stock android I get perfect 3G reception. I've read reports of the same things happening to other people, but haven't found a solution yet. I restored to stock after making a backup to try updating the PRL. I'll update again when I find out if it worked or not.
Edit - Sprint just sucks, apparently. http://www.sprintusers.com/forum/showthread.php?t=225908
When I rebooted to stock I checked the radio status and sure enough, 1xRTT. Evidently I am a moron =p
There was something wrong with the phone afterall. To fix it, I did the following:
Dial *#*#4636#*#*
You'll be presented with a menu. Go to Phone Information.
About halfway down the page, there will be a menu with a dropdown. Mine was set to CDMA. To fix the issue, I changed it to CDMA auto (PRL). I'm now receiving excellent 3G reception.

[Q] Fast and constant reboot

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.
