How to find/fix kernel issue? - Atrix 4G Q&A, Help & Troubleshooting

Alright, so I have a problem where my bluetooth and wifi don't work at all. Wifi status shows up as error and when I try to enable it, it just puts the phone in a reboot cycle where it starts up for a bit then restarts unless I can catch it fast enough to put it into airplane mode. From what I've been reading after doing some looking around on the net, it's most likely a kernel issue.
How can I figure out exactly what is causing this issue so I can flash over the corrupt kernel and try to get it to work? I've tried flashing 3 different roms but none of them fix the problem so I'd like to try to find a way to figure out which individual kernel is causing it.

Post what you've installed and what you're running. Usually using a ROM that does a full wipe will usually solve any issues. Are you using ROM manager to do your installs or CWM?

Originally I was having this issue on 1.83. When I used rsdlite to flash the stock 2.3.4 sbf, it fixed the issue for me. I later tried to install the new androidmarket apk and the issue came back.
Since then, I've used Tenfar's CWM to flash Ninja SF, Alien, the CWM stock 2.3.4 and am now running piCrust but I haven't been able to fix it again.

[HELP] Wifi/Bluetooth not working

Details of my problem are here: http://code.google.com/p/atrix-dev-team/issues/detail?id=115&can=1&start=100
Samcripp asked me to open an issue, but it was later closed as its not related to CM7.
Basically after updating to 0.19 Faux kernel and OCing, my bluetooth does not work (does not turn on) and my wifi says "error" and reboots if I try to turn it on. Logcats are attached in the link above.
Before this, I also tried the 1.35 Radio but I'm pretty sure it worked after flashing back to 1.77.30P.
I've tried everything from erasing via fastboot and clean installing stock 2.3.4, alien and CM7 -still nada. Tried restoring pds partition, nada. Tried different radios, nada. Only thing I didn't try was to SBF to stock. Can someone point me in the right direction to a SAFE SBF that I can used on an unlocked ATT Atrix?
Here is the dmesg: http://db.tt/92GSbZ4
Says something about buffer overflow, vdd.
Any help?

I got it to work momentarily but then phone froze and went back to error. I had followed these instructions: http://forum.xda-developers.com/showthread.php?t=1077329 and then did a dalvik cache wipe.
What could this be? Hardware?
Think its definitley a hardware issue. I can get the bluetooth/wifi to work by taking out the battery and tapping on the back of the phone..but then it dies later.
Next question: Any way to get "Unlocked" from showing on the bootscreen?
Had a similar issue
I once had a similar issue with my wifi after installing the same kernel. Consider restoring the stock kernel before you consider your phone broken. When you change kernels, since the kernel is central often, hardware is messed upOA component,
Have tried stock kernel, 1.83 kernel, faux kernel and kholk's kernel..all the same. Wiped cache/dalvik cache after all.
Getting replacement device from ATT. Just trying to figure out if I should send back with "Unlocked" text or not.
Theres got to be a solution, somewhere ... I can't get it replaced.
Someone...
was there a solution to this i am having the exact same problem
ive been running jokersax cm9 shortly after flashing 0.33 i noticed i no longer was hooked up to wifi. After looking into it i noticed bluetooth is also a no go.
it never gets past "turning wifi on" i have since done a complete format/factory reset, flash .33 and .4, went back to Cm7 still no change i have also flashed multiple kernels.
Last try was flashing radio N_01.77.37p still no luck
Having the same problem. Wonder if we can buy just the system board of this phone

Yes, Wifi/Bluetooth is a hardware issue! My phone just died of this same fate. If you want to take advantage of your warranty, then flash the 2.3.6 SBF after wiping all user data. BE CAUTIOUS. And can we make a big sticky for this problem? There are literally dozens of threads about this

wifi not working.

Hey, My wi-fi/hotspot shows up as error when i go to settongs and wireless networks. i had the problem with alien#4 so i decided to switch to cynanogen 7.1 and still nothing :/ is it a hardware problem or i need to flash a different baseband/kernel or what? thanks for the help in advance if anyone reples. it would mean alot haha
I had that issue when I installed one of faux123 kernels.I re-flashed the kernel wipped cache and dalvik and rebooted.I didn'tn have the issue afterwards,hope this helps out.
thanks. I tried flashing a 1.30 ghz kernel by faux123 and i have a bootloop :/
try flashing a different kernel.I notice the 1.3 works better than 1.45 for me no bootloops.try going into cwm and clear cache dalvik and fix permissions.
ok,im using tenfars recovery. should i be using clockwork mod?
i don't know what the problem is :/ i still have error for wi-fi.. but i flashed 145 cause that's all that would work

Tenfa'rs recovery is outdated. Use romracer's instead (he just updated today).
*Edit* I ran into this same problem early on when I started flashing customs mods. Ended up having to go back to my "stock" backup before wi-fi started working again. After that, I haven't had it re-occur. That might be your best bet to get it functioning again. If not, it may be a hardware issue.
haha I just got this thing 3 months ago...hopefully it's not a hardware issue. but i'll try that
MY phone is completely effed right now..like the "soft keys" on the bottom don't work and the screen sensitivity is really low..it's like my phone is destroying itself or something.
Sounds like a hardware issue. I had the same exact issue.
Wifi error, some random reboots especially after trying to turn it on.
after much testing, reading, and playing around i started getting constant reboots. You could get too the lock screen, then it would reboot.
Before jumping to conclusions about hardware go back to your stock backup.Also use RomRacers newest recovery.then start flashing kernels again and see if the problem persists.Its easy to blame everything on hardware issues but often that's not the problem.

[Q] Wifi not working after trying to flash kernel

ok, so i unlocked and rooted my rezound, everything was working 100%, then i start flashing diferent roms and it was conecting to wifi with no problems, however when i flashed ( or tried to flash ) a new kernel ( dont remember which one ) wifi stoped working for me, it scans but doesnt pick up any network. i went back to stock kernel and nothing, re-locked device and installed verizon factory Ruu for the rezound and Wifi still doesnt work. Im going crazy here please help, maybe im flashing the kernel wrong but re-locking and restoring to factory Ruu should have fixed it
I was also having the same issue and tried reinstalling kernals and nandroids. I was loading the kernal through Amon Ra interface directly and no matter what I did I still had issues. Sooo, I revised my recovery process and found that dummy me can't read instruction correctly. The issue was resolved after I did a factory reset on the rom (Ineffablis v1.0) then I followed the instructions for installing the kernal (I'm using the SmartassV2 kernal from dsb9938; flash from SD, then flashmethis file and finally through HBOOT, it's a process ok?), rebooted and I was able to get WiFi working again. I've had this issue whenever one of the additions I was trying did strange things to my phone and have sucessfully restored WiFi (about 10 times for this occurance). I've also had to do a hard reset (pulled the battery) and follow the process to get back to functioning. Hope this helps.
i locked the phone again, and ran the rezound stock Ruu and did factory reset, still not picking up any networks. the wifi doesnt give and error it scans and everything, but for some reason it just doesnt pickup any networks
If you read the complete directions when flashing a rom... They state you will need to flash the wifi module after a fresh install. So just flash the kernel over again and you will have wifi working.
Thanks a lot, finally got it working

Wifi Error - fixed -- any explanation?

Mods, I'd have liked to have posted this as a reply to Andybones' thread, but I'm under 10 posts, so please move as needed.
So, I got my Rezound from eBay and figured I'd root it and update it.
Went through the HTC Unlock Bootloader process.
Setup Perm Root
Installed Amon Ra Recovery 3.1.3
Allowed OTA to take place to get to 2.01.605.11.
Went into Amon Ra and had it install superuser and su.
Figured it was an eBay phone and should be wiped clean, so from bootloader did a Factory Reset
After it rebooted a few times, phone came up and "Wifi Error". Everything else working perfectly- 3g, 4g, voice, bluetooth... just no WiFi. Unable to stop or start it in settings GUI.
Hunted online for "WiFi Error" and Rezound and found a few posts asking about clearing cache and dalvik; another few were referencing Kernel and/or module installs.
Cleared cache and dalvik to no avail.
Searched for 2.01.605.11 Kernel and found Andybones post. Installed the Kernel and Wifi was working with everything else again.
So the question-- now that it is fixed and working-- what the heck happened to have broken my WiFi for that duration? Was it when I did the Factory Reset that I somehow screwed up my Wifi Kernel Module? If so, how? Did Factory Reset install some older module or Kernel? Or, was there something broken in my OTA? I saw mention of one other person whose WiFi was broken after OTA to 2.01.605.11-- he also resolved by using the Andybones post to install the Kernel.
Unfortunately, after seeing that the WiFi wasn't working, I didn't think to check what Settings showed for my Kernel, or to try checking mass storage for file dates or versions-- I know those could probably have helped in ascertaining what occurred.
Anybody else experience WiFi broken after OTA?
Thanks in advance!
After I got the OTA I restored my Ineffabilis GB nand and didn't have working wifi even though I flashed the original 1.x stock kernel with it. I didn't get it working until I flashed the dsb kernel, which I had been running when I made my nand. I suspect that is because installing that kernel is more than just flashing the boot.img, there's an install using other folders that happens before the boot.img flash so I guess it is altering something else.
(I didn't try flashing the modules for the new kernel since I wasn't trying to use the new kernel, at that point I was wondering why I couldn't get wifi with the same kernels others were getting it on the same ROM.)
However, even when I did a clean flash of Ineffabilis I had the same problem of not having wifi even with the stock rooted kernel posted with that ROM. I would think at that point I would not have had any traces of the dsb kernel but that was the only thing that got me wifi so I have to assume that had something to do with it.
I would think you would have had wifi working on stock OTA since you should have had the 2.x kernel and everything else.
So it would seem that both of us had broken wifi in instances when it would seem we should have had working wifi, albeit for possible different reasons. I too would like to know why. I like fixes but I prefer to know why they work and what is being fixed.
Are you willing to factory reset again? I'm thinking of going back to stock OTA again and starting over with my ROM and seeing about switching kernels. One of my concerns in my situation is am I going to be able to switch from the dsb kernel if that's the only one that got my wifi working now? Others had wifi working with other 1.x kernel using the same ROM so I know the others work, just not on my phone atm.

dsb's kernel installs wifi modules, so since u made the nand using that kernel, that is why u got an error, until u added original stock 1x kernel wifi modules ud get an error.. or flash dsb's kernel like u did.
also when u did a fresh install of ineffibiliss is does install wifi kernel modules, but no a kernel. so you would of still had dsb's kernel even after doing a full fresh instal of inefibiliss. flashing the stock 1x kernel would fix wifi as it has the stock 1x wifi modules.
this is why when people updated to the OTA, and had the new kernel and then did a nand, or a fresh install of ineffibiliss they had wifi error, they needed the new OTA wifi modules.

But the only way I could get wifi back was flashing dsb. That's why I'm wondering about what that extra stuff is in the dsb package. After going stock I flashed the original stock rooted kernel that was posted with the ROM before and after flashing Ineffabilis again and still no wifi. But others who did those same steps did have wifi. This makes me concerned about being able to switch from dsb. I want to go back to stock anyway and start fresh since my status bar is crashing and uninstalling the apps I installed right before that started hasn't fixed it. So I'll experiment some more.
Trust me, I get what you're saying and it makes sense, unfortunately that hasn't been the case which is what all my previous posts were about.
Also the OP was completely stock and didn't have wifi and that doesn't fit the equation either.

i had this problem a few times...the last two times i think it was because i had wifi tether on then stupidly i turned on verizon tether app and so wifi and verizon mobile hotspot/wifi tether stopped working and kept giving an error message...i had to flash a version of incredikernel i had laying on my card and everything worked fine..kind of wierd but whatever lol and once i believed it just happened out of nowhere so i just reflashed everything..that time wiping and flashing the rom all over again worked but all other times i needed to flash a kernel. i believe i was running clean rom all those times and once happened on ICS i think..running the latest clean rom 1.6.5 and havent had those issues yet( knock on wood)

That's what I'd have thought, too. I am/was completely stock and my update was OTA. Didn't touch any 3rd party kernels or ROMs. I want to make sure phone works as intended before considering messing with other ROMs/Kernels.
EDIT: Found this older thread which is very similar -- mods can probably close mine or migrate the posts over to the older one since my query resembles what SquireSCA experienced.

Yeah, tempted to give it a shot after doing an Amon Ra backup to see if it was the factory reset that did me in. I can head back to the Andybones kernel thread to recover again if needed. Probably not going to test it right away though. Still settling in with the phone.
One variable that I didn't consider-- when I did my OTA-- I did not re-lock the bootloader prior. Any possibility of correlation?
I would say that's very possible. I didn't relock the first time so I redid the update using con247's Stock OTA ROM with his update file.
I have a nand of my phone from right after I did my OTA without relocking. When I get around to doing my fresh installs I will restore that and check it to see if I have the same issue. I'll probably do it when I get back home later tonight. I'll post back afterwards to let you know.
So I just restored my nand from when I went back to stock recovery, ROM and kernel (all 1.x) and then accepted OTA. wifi was broken until I flashed the new 2.x stock kernel. That was from when I got the OTA without relocking the phone. I meant to check what the kernel said before I flashed the 2.x stock one but forgot. Argh... now I want to go back to Ineff and do this again to check it.
EDIT: Well, I went back to my stock OTA nand again and the kernel shows as dsb. So I can't replicate what I did earlier since I had flashed the stock kernel before getting the OTA and I guess the nand doesn't back up/restore the kernel.
I don't know what condition wifi was in when I made the nand since I didn't know to check and I just made that as a safety copy and went back to Ineffabilis right away.
I did flash the stock 2.x kernel to get wifi working on stock OTA, then restored my Ineffabilis nand and again, the only way to get my wifi back was to flash the dsb kernel. The stock rooted kernel that came with Ineffabilis didn't do it. Gonna go post on the dsb forum and see what they say. Also, tomorrow I'm going to run the RUU and factory reset and try to get this thing totally clean and see if I can use a different kernel than dsb. Ineff was just updated to 2.x so perhaps flashing the new ROM will break the chains.

Soooo... I was reading some of the ICS threads and getting really curious about installing. Saw a post by someone mentioning they're on baseband 0.95.00.1118r. Went to check mine, and I'm on 0.95.00.1017_2r . Checked the Verizon site and OTA 2.01.605.11 provides 0.95.00.1118r . Did some more digging to figure out how I got left behind using the official OTA and came upon this post:
Baseband does not update without a re-lock first.
EDIT: found plan of attack via http://forum.xda-developers.com/showthread.php?t=1467329 and will give it a shot this evening.

Off-topic: Any alternatives to using Filefactory or Dev-host to download the RUU? Has anyone done a sniff during the OTAs to see what URL is used to download the RUU? Does VZW restrict what IPs/MACs can download the updates? Or do they use a proprietary protocol? Or are the updates strictly via their CDMA/LTE, without WiFi?

Atrix, Wifi and Random Reboots

Hi,
I have a major issue with my WiFi and reboots.
Background: I am using an ATT phone within the UK on T-Mobile network.
Randomely, the other day, the WiFi turned off and when I turned it back on, it says Error....
I have tried everything I can think of; wiping and reinstalling rom, erasing everything in fastboot, updating the radio (further question on that) and also kernels! Finally I tried FruitCake to get back to stock, still no luck!!
Radio: Are radio's carrier specific, i.e. could I flash a radio meant for Europe to replace the ATT one? (I am on .36)
What can I do now, please. Thanks

If it helps, i accidentally formatted the PDS partition a while back and the reason for reboot is AP KERNEL PANIC
Any help would be greatly appreciated.
I am having similar problems. Just last night my phone started rebooting frequently after having turl's v8 build of cm9 for probably a week and it was working great. However, now I have tried wiping everything, putting on different cm7 or cm9 builds and what I have come to the conclusion is anytime I turn the WiFi on, it reboots.
It is not even connecting to anything, just turning it on makes it reboot. I was on the .36 radio with this issue, I tried using the .37P radio and it did not fix it.
Does anyone have any other ideas to try and fix?
Benny,
Do you get the option to turn it on? I'm on cm9 and it'll show up like the attached after it reboots.
No. I dont have that screen. It just says wifi error and Bluetooth crashes as well....

From the other threads I have read, I think we are boned. It seems like the Broadcom WiFi/Bluetooth chipset is borked and the only fix other people have gotten is through an actual repair. I hope you are under warranty - I'm going to revert to stock and hope they accept it.

But, how come whenever I flash a new rom, the WiFi will work temporarily, i.e. it would connect, obtain IP etc for a few minutes then just not work until I reflash?
Surely that is not hardware?

Did you use Titanium Backup, and restore apps like Maps, Music, and YouTube? People are saying this can cause issues.
Also did you restore call logs after flashing? I experienced my wifi and mobile networking dying after doing that on only some of the new roms out there lately. It's a bug with one of the base roms, that a lot of custom roms are based off of. It was fixed with a new base rom version, but some of the custom roms have yet to officially update. Updates are under way though. Try out Morrison's 0.7 and see if you get the same result. It's been updated.
Although, you could be having a completely different issue. If you mean you can just leave it running after flashing and the wifi dies, I don't know what to say.

Tried all of the above and still nothing unfortunately. Just want to update on symptoms of the phone if that helps:
Everything eventually gets more and more buggy, even recovery is really laggy and slow
Data will stop after a few days use, and only fix that i know of is to reflash
WiFi does not work, it connects for about 30 seconds after a reflash, but then nothing.
Logcat says - Failed to Load WiFi Driver (after reporting WiFi HUNG)
The phone can crash when I plug in the MicroUSB to charge, when it restarts it says AP KERNEL PANIC.
I have tried everything except for flashing via RSD lite, do you think that could work?
Thanks
BUMP,
Any help at all with this unique situation would be very helpful.
Thanks
