[Q] Kernal Help - EVO 4G Q&A, Help & Troubleshooting

So here's the deal, it feels like I can not get netarchy or kings to install on my phone no matter what. Unless the kernal is built into the ROM there is absolutely no way it is going on my phone. I always boot into the ROM, let it load up, reboot into recovery, wipe cache, and flash the kernal. Every time I do this with either of those kernals my phone will work fine for 5 minutes then start going into random reboots. Is there something special that I am not doing? I'm not a noob, have been a flashaholic since July. I just need to know if its my phone because I am seriously getting tired of it. Kernals I can use with no problem are any cm6 or ziggy kernal. I find this whole thing really bizarre.

are you running cm6? Or any AOSP rom? if you are you need to make sure that the kernel you are flashing is an AOSP kernel. The Kings and Netarchy's kernels you are trying to flash might be sense kernels and well that might explain the boot loop.

No I am not trying to run sense kernals on aosp roms or vice versa. I don't have problems with AOSP roms or kernals, basically just netarchy and kings on sense.

For instance I am running MYN RLS4 currently and every netarchy or kings kernal will send it into random reboots after proper installation.

that is pretty weird. the only thing that i can suggest is to flash the rom of choice and make sure to wipe dalvik and other caches. then try to flash the other kernel. i would even go as far as re-downloading the rom and kernel of choice to make sure that the one you have isnt corrupt or something. sorry if this doesnt help. the one time that i ran into this problem, fresh rom and kings kernel, once i wiped all caches problem went away.

Not sure if this will help but random reboots have been reported due to the underclocking on those kernels, I think there is a little blurb on it in the netarchy thread for the kernels, it is in one of the text boxes with the q and a's. Are you running setcpu? if so set the min to 245760 and see what happens. Just an idea.

[Q] cant flash another rom after first non stock rom

[solved] (forgot to flash new kernel)
after working 6 straight hours on my girlfriends captivate trying to un brick it (succeed) i think its time for me to figure out whats up with my incredible
i have flashed redemptive rom on my phone, and i tried to flash many other roms over it a day after and they keep going into boot loop (i think because it just stays at the "htc incredible" screen). is their some trick to getting a new rom flashed over the stock rom? did i miss something on all the tutorials and XDA wikis? im stumped! any advice?
i have searched for the past day for the answer (kinda why i almost bricked my girlfriends captivate because it was doing the exact same thing) thats why i came here. this is my last resort
Did you do a full wipe between flashes? You really shouldn't have to do anything special. Ill help you get through it. Oh is your inc an amoled or slcd screen. If its slcd you need an slcd enabled kernel. Do you have adb installed? If so are thaere any errors.
It can take up to 15min for a first boot. Adb will show you if every thng is going smoothly
If it doesn't boot after flashing a rom through recovery it is most likely the rom not flashing right for some reason, most likely an improperly finished download. Try downloading it again. Happened to me before on ruby rom.

i have an slcd screen and im running kings kernel #5 on my stock install. maby i need to flash the kernel again before first boot just in case the new rom changes the kernel
i have adb on my computer but i dont know how to do anything but the classic "adb shell" to remove bloat-ware and "adb Push" from working on my girls captivate
whats weird is it has done it on both my incredible and her captivate, but then again, ive done the flashing on both.
do i need to restore to stock before i install another after market rom?
You most definatly will need to flash the kernel again. Every full rom flash will flash the kernel that comes with the rom.
No you will not need to return to stock. Just flash away just remember your kernel. Most roms for the inc have amoled as the default screen type in the rom kernel.

im trying it now. Fingers crossed
It Worked!!!!!!!!!! You made my day!! i missed something that simple!! unfortunately it is boot looping but i think its probably the rom ha, but it made it far as i need to use other roms, thank you!
Well glad to help. Which rom is it.
For a sense rom i personally like virtous. Very smooth. Close to stock. Has great mods.

Boot loop on miui

well i am a little lost... i tried to update the kernel to the newest version of savaged zen. But got stuck on the white screen, so i went back and wiped both catches again, then i got to the boot animation and now thats looping.. okay so i made a backup before starting but now after wiping everything and restoring the backup is boot looping too. Any suggestions?
Try another kernel. I am using the BCblend kernel from november, it's awesome and very stable. Once you get it booted, go into your advanced wifi settings and set your sleep policy to never.
well... my backup boot loops too... wouldnt the backup have the old kernel?
It's possible your phone doesn't like that kernel either, mine didn't. How long were you running it before flashing the new kernel? I would try at least a couple more kernels and if you still can't get it booted then wipe and start over. What version of MIUI are you running?
In my opinion...if you have a good working kernel do not change it. From what ive seen every custom rom is based off a stock rom that comes with a kernel. Usually only custom kernels that match the rom version work well. So it could be the rom and the kernel dont work well together. One thing is nobody seems to list which kernel version is from which rom. So its hard to tell. Also I think your pri version will mess with compatability also. Basically newest rom versions should work with newest kernels. But if your on an older rom...the older kernels will probably work better. And usually kernels come out (it seems) before rom versions. Like new miui kernel supports 4g, but the rom does not support it yet. Also nandroid? backups should have the kernel also. Not sure bout miui backup. But wiping and installing it fresh usually works well. If not you know the deal..wipe everything..then flash the rom..and start over So.....find a good one...keep it=no issues

phone touch screen wont register my touch after rom flash

my first rom was evervolv for droid incredible. i decided to go with magnolia rom.. it all worked up to getting to the lock screen after flashing it. the lock screen wouldnt read my touch.. and i switched back to evervolv. it worked after i did. then i decided to go with Warm Z TwoPointTwo... and it did it again.. i'm getting sick of the same ole same old and i need help.. anyone have suggestions to fix this mess so i can get the roms i want???
Are you saying when you flash a different ROM, the touchscreen is not working, and if so, are you running the kernel that comes with the ROM, or something other before first boot?
Are you fully wiping data/cache/dalvik prior to flashing the other ROMs?
Do you have ample space on your SD card?
make sure you clear data/cache/dalvik and all that jazz.
you can also try flashing a new kernel in recovery, that might do something...
yeah i flashed a different rom to my phone and then it messes up.. the screen doesnt read my touch.. i restored my evervolv for it and it works fine again.. but i dont know how to flash a "kernel" that would work with the rom i want.. doesnt that come with a new custom rom?? and what is dalvik? i just press factory reset or whatever..

Dalvik is under the advanced tab in recovery. I do data, cache, dalvik before flashing a new row. I do cache, dalvik, battery(also under advanced) before flashing kernel. Dl krnel to root of sd card, flash in recovery like rom. I nvr use rom mgr for flashing anymore. Make sure u use sense kernel for sense rom, aosp kernel for aosp roms. Couple of good threads on kernels. Chads kernels work great for my phone, but its preference. Any problems just use the search function on xda, cant find answer then just ask. Good luck.
yes, i am one who likes to flash then flush
This sounds like the same issue you would get with a kernal that is not compatable with a rom. or a theme/mod ment for a different rom. I run evervolv myself and if I try anything else i need to clear/factory reset everything before i flash
i'm very grateful for your guys help. but.. i just ran into that same fix again. i flashed another kernel so i could run the rom i want and it still did it.. so i need to know the kernels that are compatible with roms.. specifically the one i want. (right now its Warm Z TwoPointTwo) but if there is a thread with this info i will try and find it. and also do i flash the kernel for the rom after i flash the rom or do i flash the rom then boot up then go to recovery and apply the kernel.. i'm sorry if i'm sounding too noobish.. i'm learning. very slowly lol
You are flashing Sense kernel with Sense ROM, yes? The kernel is flashed AFTER the ROM install.

Problems flashing MIUI?

Anyone having problems flashing the most recent MIUI, or is it just me?
I'm on MYN Warm with stock kernel. I'm using Amon, factory reset and cleared the Dalvik.
It says that MIUI is installed, but when I reboot, it just goes to the default white EVO screen and stays there.
I've downloaded and tried it several times, but same result.
Is it because it is a Sense kernel? And do I flash the AOSP kernel or MIUI ROM first?
Sorry for my scrub questions - just rooted.

Wipe data again then flash
sent from my HTC evolution running a freshly baked gingerbread with the 4gs in it
Do a full wipe, then flash the rom first; always the rom first. And if you flashed the kernel first, fine, but when you install the rom, that kernel will override the kernel you flashed, and then have to flash it again.
Also to make sure.. if your flashing the 1.3.5.. you need to install the 1.3.4 first.. then the 1.3.5.
1.3.4 - http://bit.ly/ePj9IF
1.3.5 - http://bit.ly/eY4Oal
(english)
Also, it has been noted several times.. and I've had much better luck with this rom since doing it this way.. But do a complete wipe.. then wipe cache.. then wipe dalvak.. And for good measure.. do it all at least 1 more time completely. I thought it was bs but I used to get force closes and reboots Constantly whenever i flashed this rom but ever since I wiped everything a couple times it works every time just fine. Hope this helps you out.
So I have to flash 1.3.4 first... okay, gotcha, thanks much. Just wondering, what AOSP kernel do you use/recommend? I know most people say that you need to experiment, but just wondering.
Sent from my Evo - Myn
After wiping your phone to your heart's content, flash 1.3.4, stay in recovery, flash 1.3.5 hotfix, stay in recovery, flash whatever else you need to (kernel, other mods, etc.)
I'm using the Tiamat 2.1.5 kernel, but I think I like the performance of Savage (NOT SavagedZen) 1.6 better/
Aight, thanks guys. Made a Nandroid backup, flashed everythink like you said and Savage 1.6 kernel, and everything is running smooth as butter. Thanks for the help

Q: what should I do?

Hi, so I'm super green but itching to load custom kernel and rom... So my Evo is rooted and have seen some pretty sweet roms, lol, kinda scared to flash and not sure what roms go with what kernals, do I even need a new kernal? What I really want is a kernal I can overclock to 1198mhz, and a rom build based on honeycomb and or gingerbread that is 100% stable or as close as I can get... Help? Lol...

hahah exited aren't you... welcome to the root world!
you asked for hc/gb. google hasnt released hc source code yet, probably not until ice cream, so there is none of that. you can however download cyanogen(mod) 7, which is almost totally stable.
http://mirror.teamdouche.net/?device=supersonic
there's the mirror link. download either rls4 or nightly 33. nightly 33 is a bit funky bcuz cyanogen is pulling an april fools prank saying he sold cm to teh duck revolution, and the rom is now called 'teh duck uber distro'. so maybe rls4 or just wait for the next nightly.
everything works. 4g (with one bug that there is an annoying fix for), hdmi (download hdmwin from the market) gps (with a fix) and everything else is perfect. it is still in beta/nightly stages, but should be done soon. it is my daily driver, as well as many other peoples. this rom is crazzzy popular. try it for sure.
start with stock kernel, but i'd try both savaged-zen and tiamat kernels on it. they will both give you much better battery. tiamat tends to give slightly better performance/quickness but savaged-zen (on custom SAVAGEZEN governer) gives fantastic battery. try them both!!!
again, welcome to the community. hope this helps.
Where do I get the kernals? And what process do I use? I have clockwork premium... I just don't wanna miss a step a jack myself
Also, is it gonna wipe my phone, do I need to wipe it? No issues with that though as I do it all the time... And thank you so much for the feedback BTW, still a little confused...

ok, first of all, clockworkmod isn't the recovery you want to be using. download amon-ra's recovery here http://forum.xda-developers.com/showthread.php?t=705026 make sure you get the pc36img.zip. put the pc36img.zip on the root of your sdcard (that means not in any folders) MAKING SURE IT IS NAMED EXACTLY PC36IMG.ZIP. aka just dont rename it. then power off your phone, and once it is off, hold power and volume down. you will see a white screen with scateboarding droids at the bottom. this is your BOOTLOADER SCREEN also known as hboot, and you see it quite often. so hboot will scan your sdcard, and find the pc36img.zip. hit volume up to accept the 'update'. then once it is done, volume up again to reboot.
you can download kernels from the evo android development subforum right here at the xda.
so first flash your rom. you can either boot up into it, or just flash the kernel right away. flash the kernel just like you would a rom, but without wiping.
enjoy.
any other questions, ask away.

100% agree. Amon Ra imo is the much more stable & user friendly recovery
Alright, so, can I do all this just from my phone? Is a pc recommended? Will my stock kernal overclock? Never flashed a rom before, I'm an electronic/computer tech so I pick up shniz pretty quick but still don't wanna b---- this sucker...
Sent from my PC36100 using XDA Premium App
you can do it all from your phone if you want. i perfer downloading on my pc and transferring from there in case i want to modify anything, but you can always just dload on phone. make sure the pc36img.zip isnt in download folder or anything if you do. it needs to be on the root. your stock kernel can't overclock sadly. if you have never flashed a rom before, then cm7 will be crazy different than stock rom. most custom rom's are based off the stock htc software, just modded. cm7 is aosp, which means it is stock GOOGLE software. htc spends quite a few months modifying htc sense into google software, so the speed and memory increase is very noticable. just wipe data, cache, and dalvik cache when switching roms. you might want to backup your apps and their data using titanium backup. just dont backup system data, that can cause problems. then flash the rom after wiping, flash any kernel or addons you want (dont forget to flash gapps if it is an aosp rom, bcuz if you dont u wont have the market or anything) and reboot. for any other mods you install after that on the same rom, just wipe cache and dalvik cache and then flash away. wiping data between roms is always reccomended. if you want to stick with the cm7 nightlys, then all you need to wipe is cache and dalvik. there is never much of a problem with just flashing one over the other without a data wipe.
and forgot to mention, you cant control amon-ra recovery with rom manager. but then again, rom manager is just a touch screen version of recovery. you get used to the volume/power keys pretty quickly.
ok, im freaking out now, my phone is locked in the cm little surfer droid with the arrow circling around been constantly running for about 45 mins, im fuct, really fuct without my phone!!! its my only internet too!!! PLEASE HELP!!!
Did you do a factory wipe, Clear the cache & wipe Dalvik?
Sounds like it just wasn't a good install. Do the above in recovery & reinstall your ROM
ya did you wipe? doesnt sound like it. make sure data, cache, and dalvik cache are all wiped successfully. also make sure you are using amon-ra recovery. cwm can sometimes give you problems.
