[EVO 4G Original Development] NeedToMod:
I posted this on the classic rom thread as well since I'm using both the classic kernel and Underworld.

Anybody having problem with WiFi?

I'm running classic with underworld kernel. WiFi drops out randomly while nothing else in my house does.

Would be more than happy to pull a log ( if I even need to) if someone could give me some guidance.

I've already turned 3g off cause I read it on Google.

Any help is appreciated. Tia.

Is it possible to add ZSL?

Is it possible to add GPU OC to the kernel?
[EVO 4G Original Development] rickmatic:
would this kernel work on Synergy Rom?
[EVO 4G Original Development] Chaz187:
I don't think it will!
[EVO 4G Original Development] Notorious:
Yes but it wont work on Synergy+godmode only the original one
[EVO 4G Original Development] ca1ne:
It may occur due to the slight undervolting I did

to the Wi-Fi for battery savings. Outside of that if you are on a higher channel or have Wi-Fi always on disabled this may also occur.

give me a link to show me where it's at and I'll try to add it

i believe most oc in evo had to do with Rom side, i can look into kernel side if you want I'm just concerned as to the results.

Should work, but you would need to manually flash the modules since i believe the setup is different... Or an easier way would be to take lionfish synergy zip and change out the zImage and modules in that zip and flash it
[EVO 4G Original Development] bennyboy78:
I don't really know where it is, like files and all. Maybe from the Amaze ? I know some kernels have it, just couldn't find a thread for any files/modules/source

Random reboots anyone?

I can't put my finger on it(although many webpages I've seen seem to do so) but ever since I installed this on my rooted EVO, I've been getting random reboots. The reason why I can't say for certain its the kernal is because I was only on Gingerbread 2.3.5 for like a day or 2 before flashing this kernal and everyone and there mother says that 2.3.5 has random reboots. But I think I can say without a doubt, that the random rebooting started after flashing this kernal, only problem is, it wasn't immediately after.

It seems to be getting worse, but some of the things that seemed to have made it worse(in chronological order) were:

-overclocking/underclocking(after messing with the max and min clocks, had a couple reboots, again plugged in to wall)

-replacing the boot animation and the mp3(I did have my phone plugged to the wall)

-replacing the splash screen(rebooted right after my phone booted, it was a low battery as well, plugged in to the wall)

-CHARGING especially, when it's plugged in to the wall(I assume because of the heat) it reboots every 5-15 minutes

I don't have the fast recharge on, I did OC, but that didn't seem to matter at first(it started random reboots after I installed my custom boot animation), and when I plug my phone in to the wall, it gets HOT ~40-50 C. But when I plug it in to my PC it doesn't reboot, then again, it doesn't get hot either. Mystery is, I never had this problem before I did all these things. Not once, has my phone rebooted like this until I decide I want to update my phone and customize the CRAP out of it(just 3 days ago)

EVEN STRANGER, the phone seems to reboot randomly and seldom REGARDLESS if its charging or not or if I'm using the phone or not. I only started experiencing THESE TOTALLY RANDOM reboots after I installed the custom boot animation and mp3.

I point the finger at this kernal because I never had this problem until I had this kernal, should I try switching to something else? Is anyone else experiencing random reboots with this kernal? Do I sound stupid because this is typical for overclocking? Please, someone throw me a frickin' bone, I'm somewhat new to modding. I had my phone for about 2 years already, I rooted it last year, never updated until now and finally have a custom kernal over a deodexed 5.07 rom(by Captain_Throwback, so it has some mods already).

Radios are up-to-date(I think, its hard to find radios these days, but I got 2.15____12.19), I see no correlation with the network or wifi and the reboots. I think it just might be the heat. I can't explain those other reboots which occurred when I was texting(twice) and calling(once) and not doing anything(I think once), and btw, I got my first custom boot animation installed TODAY(actually just 20 hours ago).

SORRY for a long post, I tend to rant and ask TOO MANY QUESTIONS but I love to learn so PLEASE don't be rude to me. Also, I tend to get people asking me for info I said in the long posts, so if you WANT to help, just read the whole thing and it MAY save you some trouble of waiting for my reply.
[EVO 4G Original Development] Robobob1221:
Did you wipe cache and dalvik cache after flashing the new kernel?
[EVO 4G Original Development] ironman120693:
Yes, I did. Just to double check, I'm doing it as I reply...

... just wiped 'em, now I gotta use it for a while, I found out that as long as the screen is off, it won't reboot like that...

... clearly, my phone can't run at 1.228GHz, phone just froze when I put it there(also a contributor to the rebooting, I imagine)...

... okay, after charging and using for about 20 minutes, and right when I started typing this last line, the phone rebooted.

I think it may be connected to the overclock I did that froze the phone first. See, I did that first when I installed the kernal, I assumed I could just restart and not go up to 1.228GHz and just stay at 1.113GHz and it'd be fine. I was also experiencing these reboots earlier today even when I had my phone downclocked to about 860Mhz(I think). But as long as music is playing, or the screen is off, I don't get the reboots... strange. And when it reboots randomly, the 4G is constantly "turning on" once the phone boots up. Sometimes it seems like certain actions force the reboot, I think that was the overclocking, but the totally random ones are strange.

I'll see, I'm gonna wipe the cache/dalvik-cache and NOT mess with the operating frequency and see if it stays on without music on. If it is just the clock speeds, then it might need more voltage right? I can't control the voltage though, is that allowed on this kernal? If I can, then how do I mess with the voltage without buying an app or even using an app? Maybe a fresh re-installation of my whole system would work(possibly)?

***EDIT***

Took another look at the info on the original post. I think I'm just going to try another ROM. I'm thinking of trying the CIUI 1.0, I already downloaded it. I would rather keep my rom and use this kernal, but that's going to require some extra modding to my rom(since I will not be able to control voltages as it is) and right now, I think I just want my phone to function properly. I love the certain aspects of the sense UI but I really only use the status bar. I'll just try it out, if I don't like it, I can always do a nandroid restore :)

***Update***

Music doesn't stop it from rebooting. I've decided to switch to the Nitrous Rom just to check it out, but then I'll check some other roms, and maybe I'll end up using this kernal again. I'm gonna really clean my phone out, the SD card is full of junk(unused app data, trash data, music no longer needed with cloud services, etc.).
[EVO 4G Original Development] jabdulk:
What is the best governor for battery life? I was using Interactive X on version 7 and getting great battery not the case on version 8. I have undervolted also.
[EVO 4G Original Development] buckhunter:
I always run ondemand but some phones like different things.
[EVO 4G Original Development] ca1ne:
On-demand is pretty good..and the most stable.

Ironman, can you increase your voltage mins by 25-50. Stone phones don't like the undervolting at low MHz. And if that doesn't work, try setting your min frequency to something higher.
[EVO 4G Original Development] ironman120693:
That sounds like a good idea. I have nitrous on right now, but im probably gonna switch around. And I may end up buying voltage tweak for the profiles and voltages. Mainly for profiles and the widget. I give you thanks!

RE: Usb tethering

I've also had this issue, I've tried it both with fast charge on and off.
[EVO 4G Original Development] ironman120693:
So I switched to a 5.07 based ROM that came with a stock kernal and flashed UW on. I haven't had any problems. The reason I was having problems was because I OC'd too much for the voltage and the phone locked up, upon reboot it just starts with random reboots, once cache and dalvik is cleared, they stop. Just as I was told to do(I really thought it wasn't this due to clearing the caches multiple times while on the kernal, but then again, I was also flashing other things on so I really didn't give it a chance to run clean).

I have a question though, the rom I have was supposed to have the hotspot hack backed in, it didn't work, so I was wondering, does this kernal disable the hotspot hack? Does it modify framework.jar? I think I first tested the hotspot after I flashed UW, but I'm not sure. Both the hotspot hack and kernal are from you btw so I know if anyone knows the answer, its gotta be you I know the ROM came with the hack so I think what fudged it up was the kernal. I keep getting the message that says "Your not subscribed to this service" or whatever it says.
[EVO 4G Original Development] ca1ne:
The kernel does not modify any Rom pieces. The several mods that are out there do overwrite pieces of each other though.
[EVO 4G Original Development] jlmancuso:
Ok here is my issue. I am running Alien choas which is 4.67.651.3 based. It came with v0.6 kernel but I upgraded to the v0.8 to gain ext4 support. After upgrading I lose my data. I am on 004hw using the latest firmware and using smelkus 4.3 recovery. First time I just flashed kernel and wiped caches on the rom I had been using for a couple of days. Second time I did a clean install of rom and flashed v0.8 kernel at the same time. I have also tried the recovery superwipe option but so far no matter what I try I do not have data (3g) wifi works fine though. When I nand back to decks reloaded I get my data back.

I would like to keep my alien choas rom because it has the best battery life I have ever had from a rom. Even with a heavy load with 3g on I pull no more than 300mA (really I cant remember seeing more than 230mA). I can run it with ext2 and the v0.6 kernel and have no issues but would like to have ext4 because of the added features it brings to the file system.

Thanks for any help yall can give.

Peace,

Love, and

Happiness

Have you tried toggling mobile network in network settings?

An enviousOG
[EVO 4G Original Development] jlmancuso:
I have. Also turned radio off and on a few times. Flashed different prls along with multiple reboots. If only it was something that simple.
[EVO 4G Original Development] Robobob1221:
You could try manually placing the lib modules and rebooting and see if that works. Have you tried connecting to wimax service?

An enviousOG
[EVO 4G Original Development] jlmancuso:
I will never have wimax since this is a phone flashed to cricket. The wifi works. As far as the libs go I have not done it manually but I extracted the rom late last night and edited it with everything libs, kernel, and modded the installer script and came up with the same issue after flashing the modded zip.
[EVO 4G Original Development] krwdre:
Try accessing your EPST via ##3282#, go to data profile, press menu, and click restore. Once it reboots your data should work. If it doesn't work once its booted up again, turn data off and on again.
[EVO 4G Original Development] jlmancuso:
um i doubt i can do the data profile restore because i am on cricket. that would restore the old sprint setting right? i am going to do a little more playing with it tonight and report back on what happens. thanks all for the suggestions but please keep in mind that this is a phone flashed to cricket and not on a sprint network.
[EVO 4G Original Development] jlmancuso:
wow yall will love this. it is all working like a champ now. it appears that the kernel download that i did from my phone was slightly bad. it installed and ran but as i said earlier it broke my data. i redownloaded everything from my pc (rom and kernel) did a full wipe except sd-ext. then reinstalled rom then kernel and now it all works correctly. just goes to show that md5sums can show you what you are not seeing. it is just wierd that the download was bad yet it installed without an error.

thanks everyone for the help.
[EVO 4G Original Development] Chaz187:
Alot of time a bad download gets overlooked! Glad you got it working!!
[EVO 4G Original Development] ca1ne:
Unfortunately i can't test this due to my evo being no longer in a data plan. Is anyone else having data problems?

Also just to be safe please confirm the md5 of your download to make sure it matches. Never know if one byte or bit got switched in download.
[EVO 4G Original Development] Dgsaxhitman84:
I had some similar issues with a different rom I was using for a bit... I wiped and reflashed and all the bs about 5 or 6 times finally I got it up and running by doing a new download and it worked perfectly after that... So I always say when in doubt try the easiest possible solution 1st
[EVO 4G Original Development] Chaz187:
+1. I always say if problems try a new download!

RE: Usb tethering

I also have this problem, both with fast charge on and off. I'm running tommytomatoe's Classic rom, but had the same issue with stock 4.67
[EVO 4G Original Development] sonwon:
On my phone the light sensor stops working when plugged into AC power. I have done much googling and believe light sensor problems are common. The light sensor works just fine when on USB power or battery so I know it is not a light leakage problem. Part of my google search suggest the kernel, Hboot, and / or ROM could be the problem. I am running Underworld Sense Kernel v0.8 with HAVS no SBC. My ROM is MikG 3.11. When I have time I plan to load the stock kernel to see if it fixes the problem, however I have my doubts.

1) Does anyone have any information or tips to fix this problem?

2) Are there any settings in the kernel that could cause this problem?

3) Does Hboot perform any initialization of the sensor before it loads the kernel? I just don't see this happening but...

I'll take all tips and pointers.
[EVO 4G Original Development] Dgsaxhitman84:
So I need to know a bit more information...The battery is still charging correct?
[EVO 4G Original Development] sonwon:
Yes, the battery is charging. Another thread suggested reloading the MikG ROM and testing, I'll do that tomorrow and report back.
[EVO 4G Original Development] Dgsaxhitman84:
Ive been running MikG 3.11 as my daily with Underworld for 4-5 months now and I would suggest a complete wipe and reinstall of both MikG and Underworld... That should do the trick if it doesn't I have another idea as well but try that first and report back
[EVO 4G Original Development] sonwon:
Agreed MikG 3.11 and Underworld are very stable. This is the only problem I have found. And it may just be my hardware version 0002 that is the problem. I'll be reloading tomorrow and let you know what happens.
[EVO 4G Original Development] sonwon:
Loaded MikG, didn't load the Underworld kernel. Same issue. The Underworld kernel and HAVS is not the problem. On power the lowest reading is 90, on battery it reads down to 10. Using LUX sensor to read light levels. It works well with the sensor in this phone. If you cycle the power enough times it will read 10 while on power but soon adjust back up to 90 after a few seconds. I am starting to believe this behavior is written into the light sensor driver, maybe to provide a brighter screen when on power. Does anyone know where I could obtain the source or binary code so I could decompile the driver? Is there a file that controls the light sensor settings? Anything else I could do?
[EVO 4G Original Development] sonwon:
Also, I loaded this [KERNEL] OTA 5.07.651.1 Stock Kernel - UPDATED 30-MAY-2012 to confirm the behavior and it is. So I would still like to access those drivers for decompile fun. Something is changing when the phone is plugged in.
[EVO 4G Original Development] ca1ne:
As far as I can recall, they never released source for that ota.
[EVO 4G Original Development] Chaz187:
I haven't seen any release of it either! But it was a great run when captain threw our his version of the rom...... To many bugs for me though!!
[EVO 4G Original Development] sonwon:
I don't think the version is important since I believe every flavor of kernel/ROM for this phone has this behavior. It must be a driver or editable file.
[EVO 4G Original Development] Captain_Throwback:
Bugs? What bugs?
[EVO 4G Original Development] ca1ne:
Captain, I'm so sorry I haven't gotten back to you on the edits. It's been crazy and I've been barely able to squeak out some kernel stuff
[EVO 4G Original Development] Chaz187:
Sorry I should have said yours was awesome but the others people made from yours had to many bugs because of the mods they tried from the old its didn't mix well with the new! Sorry for the confusion!

Thanks,

Data loss

I have been running v04 no sbc for months now. On Wednesday, I finally decided to upgrade to v08 nohavnosbc.

After flashing the new version, my download speeds went in the toilet. I mean 9kbs! My upload speed was unchanged.

I tried everything...changed radios, wimax, nv, pri...every combination I could think of. I even called sprint to complain about the download speeds thinking it had something to do with hurricane Sandy (I live near Philadelphia).

Surely it could not be related to the kernel. But after realizing that the kernel was the only thing that had changed prior to the download speed loss, I decided to revert to v04.

After flashing, my speeds were back to normal. Has anyone had a similar experience? I have never had this problem with any previous kernels, including underword.
[EVO 4G Original Development] sonwon:
I've been using V0.8 for over a month now and I din't see any changes in speed but my speeds have been in the toilet for over a year which is why I am leaving Sprint next month.
[EVO 4G Original Development] buckhunter:

You can, or even add them to an init.d script. Read the kernel info thread. It will explain lots of things to you. I would link you, but I am on my phone. Bookmarks are on my pc. I'm sure someone here, will have the link. If not, I will link it later from my pc

Anyone running this with Mikg 3.11? I am testing anthrax right now but am looking for something with newer governors and better battery life. Trying to set up something for my wife's EVO so i need good stability. I am coming from an aosp on this phone too so i am used to all the tweaks built in.

[EVO 4G Original Development] Evocm7:
I know. I used sbc for almost two years when I had my evo. But it runs a little warmer with sbc. My girlfriend has it now and I make her keep an otterbox on it at all times so it doesn't breathe well.
[EVO 4G Original Development] CheapSk8:
Thanks for the feedback.

How was the stability? Boot loops and hang ups forcing battery pulls? I think It's more common on aosp Roms but I need to make sure my wife isn't freaking out about her phone every other day. :)

---------- Post added at 12:53 PM ---------- Previous post was at 12:49 PM ----------

Breathing is overrated. :P sbc makes a nice difference for battery. I have a cheap case (go figure) that covers back and sides with a felt or something liner on the back piece contacting the phone and It's been fine with sbc kernels. Over heat actually occurred only this summer with stock ROM and kernel plugged in in car with GPS going for 2 hours parked in direct sunlight.
[EVO 4G Original Development] buckhunter:
Mine ran great with no boot loops or other issues.
