how install new kernel - General Questions and Answers

please help me. I don't kown how to flash my htc wildfire in order to install new kernel and also overclocking

I am still very new at this also. But I have found searching will get you your answer a lot faster then waiting for someone to reply (not saying you guys aren't a huge help because you are) just saying I have always had lots of luck just searching threw the forum.

flash it usong cwm or odin

You flash kernels just like you would flash a rom. The difference is that when you flash a kernel you aren't changing the UI. Just place the kernel on the root of your sd card. boot into recovery and flash it just like with a rom.

Flashing Kernal Question

A few questions as this is all new to me.
Do all ROMS require you to flash a new kernal?
Do you flash a kernal the same way as you flash a radio? (PD98IMG File and Hboot?)
I appreciate the input...
ROMS should and typically will come with the recommended kernel, however, some kernels do work that aren't the packaged one. Always be careful when flashing a new one (backup, backup, backup!) because sometime they don't always get along with the ROM you have running.
Also, most of them should be flashable .zips that can be ran through CWM.
At least in my experience with various kernels
Hope this helped!
Kernels are included with every rom I have ever tried, and if you want to use a different kernel than the one in the rom, you have to make sure that is compatible. A good rule of thumb is if it a sense based rom (custom user interface that comes stock on the inspire) you have to use a sense based kernel. If it is a ASOP rom (Android Open Source Project, like Cyanogenmod 7, or MUIU) you must use a ASOP kernel. They will specify in the OP. And I have never heard of flashing them through HBOOT, or FASTBOOT. In my experience it is always through CWM recovery, and you flash them just as you would a rom, theme, or anything else. Move the .zip file to the root of your SD, choose install zip from sd card, scroll down to choose zip from sdcard, then choose the file. When it is done hit back and then reboot. Easy Peezy.

kernal == kernel
Most users will flash kernels through clockwork like a rom. I flash them through fastboot, you can fastboot flash zimage(or boot), or fastboot boot zimage , which lets you boot the kernel before actually writing it, fastboot flashing requires eng s-off, which you probably don't have or need

After I root...

So, I am going to do a lot more research prior to rooting, but I had a couple of general questions that I was wondering about, before I begin the steps leading up to rooting.
1) I presume the easiest way for me to root my Thunderbolt is the Revolutionary Root? This will take be through rooting and installing the CW recovery that I need, correct?
2) Right after I root, If I want to install roms/kernels? than I can just get Rom Manager from the android market?
3) Once I install Rom Manager, can I just flash a rom that is compatible with my Thunderbolt? Can I just flash a kernel that is compatible with the Rom?
I suppose where I get a lil lost is the flashing compatibility part. What kernels work with what roms, what roms I can flash... I have read a number of articles, so I suppose what I'm asking is...
Will the process more or less be: Revolutionary Root, Install Rom Manager from market, flash a rom (just the most popular one). Is the Kernel flashing piece important? Do I need to flash a different kernel? Is it easy to tell in Rom Manager which kernel/rom I can use?
Yes use revolutionary to root and install custom recovery (cwr). You can use ROM manager to download custom roms if you want, only roms for your device will show up. Or you can download custom roms from forums, this is the method I prefer.
Just use kernel that comes with the Rom for the time being some developers include a custom kernel and others make modifications to the HTC kernel itself. Kernels are seperated in development section having to do with sense and aosp that is the first way to seperate them. Second would be leak the kernel was based on such as imo test 3.8 was based on newest leak so it works for just about if not all newest sense roms. When in doubt fire up a question in the Rom thread itself and ask what kernels those people are using, find a Rom like BAMF or thunderstick or synergy where the developers or support staff are very active.
Also you will need to flash a new radio right after rooting if you are still using froyo, I am using newest leak but different phone work differently. Once you install the radio VIA Hboot. Reboot phone and remove zip file from root of SD card now place your Rom image on SD card and reboot to recovery and install your new Rom.

This is good info.. thanks.
Well, I am upgraded to Gingerbread as of VZW's last update and still unrooted and stock.
So, if I were to root (using revolutionary) and install Rom Manager... could I just install something like Cyanogenmod or BAMF right through Rom Manager?
What do you mean by kernel that comes with the Rom? The kernel that is listed to use with the Rom? Or do you mean if I flash BAMF or something popular, just leave whatever kernel I have as is?

When you flash a rom it flashes the kernel too with whatever one the devs packed with it.

Okay, clear enough.
So, for someone like myself, just use revolutionary root, install rom manager and play around a lil with flashing roms using rom manager for awhile. I understand that I can install roms from my SD card, but it sounds like at least initially installing roms right from rom manager would be the simplest. I can also not worry about installing a different kernel during this "honeymoon" phase. Just pick the latest version of whatever Rom I want and flash the rom?
After you root you need to install superuser so CWM can function. I have read that some people flash their CWM via hboot after s-off and then go right to recovery to flash the root gaining RUU, then enjoy your root.
Do not flash ROMs right from CWM reboot to recovery clear data/cache and under advanced davlik cache and then install Rom from install from SD and choose zip file and I always store mine in downloads since I download all my roms right to my phone and download md5 checker from market and always check the md5 if it does not match don't think its a mistake redownload and try again.

Agreed, it is better to install the ROM through recovery instead of installing through ROM manager as sometimes it doesn't work right.
Don't forget to use thank you for all you great answers.

[Q] I9003 bricked

Can someone help me....(sorry for my bad english) today i traid to flash [ROM][LF2][15.10.2012]TheFrankenstain^MODv.3.8 #1 after that it was keep loading at the" android" logo so i tried to flash it again...but now it is stuck at the samsung logo and volume up + lock+ home (recovery) now work anymore
Did someone know how i can flash it again without recovery?
PLSSS HELP
-Removed for Personal Information-
i think it is not bricked, it is just a bootloop. check if your downloaded rom is complete. beter redownload the rom and flash it. follow the instructions on flashing on that thread and you will have no problem. flash a stock rom first using odin then flash the custom rom afterwards
Ok thx guys...and i have 1 more question ...there is a diference if i flash stock and after that i flash custom? is smoother or faster or idk...?
i saw in some printscreens that they get high quadrant score but mine is max 2300MAX ever
it is always advisable to do a clean flash ( stock rom first before custom rom). but some custom roms have the option to directly flash from one custom rom to another. everything here is trial and error. so whatever works for you may or may not work to others.

[Q] Stuck on green htc logo

Hello.
I currently have my pico with stock rom, with sense 3.5. and i'm tryin to flash a new rom, but every time i try to flash one from this thread ( http://forum.xda-developers.com/showthread.php?t=1754876 ) i got stuck on htc logo screen. and i cant get passed it... i've wiped everything, reflashed kernel, reflashed stock, but still cant get it to work. maybe these kernels arent for stock roms, if they're not, can you point some kernels that work on stock?
thanks in advance.
Stock rom should have stock kernel too.
Flash the gingerbread kernels.. they must work. PS: The ROM.zip already contain kernels that get installed when the zip is flashed.

where can i find those gingerbread kernels? so if they're inside the "rom.zip" is it possible to "extract" them to a flashable zip? only the kernel withouth the rom itself...?
Gingerbread kernels are in the Index of all kernels..
From the ROM.zip if you want to extract them then just extract the boot.img normally and also extract the modules from the zip .. in /system/lib..
In fastboot mode flash boot.img via :
Code:
fastboot flash boot boot.img
and
then via adb push the modules. I suggest you search a bit and find some answers yourself . Its easier that way cause these questions have been answered millions and millions of times. So use the search function
i've searched, and believe me when i say that i havnt found anything about this... all the kernels i go for, on the thread only talks about the kernel itself and not the roms compatible... and i've tried that method and got stuck on htc green logo... thanks for answering
these kernels work on stock rom:
1- cranium kernel
2- ateeq kernel
3- garuda's kernel
search them in the development thread I hope you'll find them.
i've tried all those kernels... one by one and never got passed the htc green logo... always get stuck there... i tried flashing trough fastboot and trough recovery... nothing works... any other suggetions?
try to flash ateeq rom then ateeq kernel..it works for me.
but i dont want to have ateeq rom, i want to stay with my stock rom, but change the kernel... only that. but thats for answering. i'm getting used to the idea that i cant be changed (the stock kernel).
thanks
Need urgent help
i had rooted my pico months back and was on different custom roms......now i want 2 get back to the stock rom which i have downloaded Odexed Stock ROM Flashable Zip (With Link2SD Support)(Revision 3)(http://forum.xda-developers.com/showpost.php?p=40385554&postcount=76) and i have flashed this rom 5 - 10 times and everytime i reboot after flashing the rom.....i am stuck on htc boot logo.....can u plssssss help

Can someone answer these couple newbi questions for me

So I am new to htc and new to what to do, been on Samsung for years and htc is way different.
First, once I update firmware will it be safe to flash the roms in the android development section even if they are from July or August ?
Do the Roms include kernels or do I need to find one and flash it after I flash the rom along with gapps ? If so what kernels do you recommend and /or do you have a list of some of them ?
What is fastboot and how do I use it? I am updating the firmware through sd card method but also want to update the twrp and I heard that is done through fast boot. Does that require a computer or?
Thank you for taking the time to read my questions

First off I assume you are s-off and unlocked via firewater or sunshine.
1) this is only anectodal but I ran ViperROM 1.8 (4.4.2 based) with the 4.4.3 firmware for a few weeks without issue.
2) all Roms come with a kernel. Some are stock, some are custom but they all come with one. ASSUMING you are s-off then the packaged kernel will be flashed along with the rom. If you're looking for a custom kernel make sure you find a Sense/GPE/AOSP kernel which matches your rom type (SENSE/GPE/AOSP) and flash it AFTER flashing the rom. Flashing a rom will overwrite whatever kernel you previosly had installed with the new rom's kernel. I am currently runing ViperROM 2.5 which is a Sense ROM with the EliteLunar kernel (sense version) with no issues.
3) fastboot is an interface between a computer and your phone. I always find it alarming when people ask this question. Learn and become familiar with fastboot BEFORE YOU FLASH ANY ROMs OR ZIP FILES IN RECOVERY. I'm not being rude, I assure you this is sound advice. Many fastboot tasks can be performed with apps like flashify or by a flashable zip file which many devs are kind enough to create. However, having fastboot set up and functional (that includes knowledge of how to use it) is irreplaceable if/when things go downhill.

Thanks for all the info. So if I am on 4.4.3 and want to flash a 4.4.2 rom just flash the 4.4.2 firmware just to be safe before flashing the 4.4.2 rom?
Also where are the kernels located ? Are they carrier dependent as I didn't see any yet browsing but didn't look hard either.
So I can do flash boot through flashify and be ok? Now all roms and kernels are flashed through twrp tho right ?
EDIT: actually fastboot can flash rom and kernels so no real need for custom recovery other then for convenience?
Btw do you have a kernel recommendation for aosp, sense, ? I already saw your recommendation for sense above.
Thanks !!

I have a feeling that it's simply not necessary to downgrade your firmware in order to run a 4.4.2 rom but you should find a more reputable source than myself. I'm just trying to answer these easy questions to save time for the guys who really know what they're doing. Once you do start flashing things, always make sure 1) they are for your device (and carrier, unless unified for all carriers) and 2) the md5 of the downloaded file matches that provided by the hosting website or the OP.
I'm not a fan of flashing utilities simply because I've heard of instances where they don't work correctly. For example, I keep hearing how the TWRP manager app flashes TWRP to the system partition on Verizon devices and sends the phone into a sort of recovery loop. I would suggest gaining knowledge about the fastboot flash command "fastboot flash <partition name> <filename.extension>" and how to enter and flash within RUU mode.
My experience is that ROMS and kernels are easiest flashed through a custom recovery especially when the developer packages it with an Aroma installer script.
A few Sense/GPE custom kernels exist for verizon. There's MassStashed and Checkm8 (no longer maintained?) for 4.4.2 roms. Also, for 4.4.3 roms I only know of the EliteLunar kernel which isn't on XDA although you can find a few links to it in the forums if you search. Last I knew, there weren't any AOSP kernels which work with verizon but that might not be true anymore. The general HTC One m8 forum may have some kernels which aren't represented in the verizon-specific forum. Just make sure and find out if they're compatible with verizon devices. I'm pretty happy with sense so I haven't wondered off to AOSP like I usually do.
so do you recommend to use flashify or no?

I'm not saying you shouldn't use flashify, it's awfully convenient. Just make sure you're using it for the convenience and not because you don't know how to accomplish the same tasks in recovery/fastboot.
