[Q] What's the best way to flash a kernel?

Yes yes, I'm quite a noob when it comes to this but I've heard so many ways of flashing a new kernel. So what's the way you flash it?
I've heard:
1. Wipe cache, dalvik, and battery stats and flash kernel.
2. Charge until full, wipe cache, battery stats, and flash kernel.
3. Wipe cache, battery stats, flash kernel, run battery to 0%, charge until 100% and turn phone on.
I'm currently using method 2 but all I really wanna know is if there is a "right" way to do this.

Really people do it different ways but to me its all the same .give your kernel like 2 days to get use to your phone and see the results

I always wipe cache and dalvik and then flash. I only ever wipe battery stats when flashing a new ROM and I always put a fully charged battery in after flashing but before the first boot.

Thanks guys. Yea I've always stuck to my way but I guess to each their own. I now have the sudden urge to flash something haha.

Battery stats want reset!

I'm using android revolution 4.0. Its working perfect, but the time on how long the battery has been without charging will not reset either by charging or reboot. If I reboot into clockwork mode an reset battery stats it will, but then it hang again.
What will be erased by deleting dalvik cache, and is it a chance that will help?

deleting dalvik cache wont help.. but that rom is in beta its not meant to work properr at this stage because its a leaked rom and dev's are working hard to make it stable in their releases... that rom is not for day to day use.

When to wipe cache and dalvik cache

Hello people!
Have searched the forums and also tried googling but have not found a certain, conclusive answer to my question.
The question is when do we have to wipe the cache and dalvik cache?
I know what to wipe when flashing a new ROM but what about radios, RILs and kernels? What do we have to wipe when flashing the above so as for the phone to run optimally? Before or after flashing them?
Thanks in advance

Developers of the rom will tell if a full wipe is needed , if your updating. If your coming from another rom, you need to perform a full wipe.
No wipe required when flashing radio, Ril and kernel.
If you are going to perform a wipe you do it before you flash anything.

You mean you don't even have to wipe battery stats when flashing a new Radio?
I thought otherwise but I am not certain...
Anyway, thanks for answering

As far as I know you don't need to, the only time bat sat are recommended to be wiped is when flashing a rom and you have battery issues. But others say wiping battery sat doesn't really help with battery..

Ok thanks for the info!

I think there is something to multiple wipes!

I was on here late last night and was looking thru a thread and someone said when you wipe cache and dalvik you should do so several times. I had some issues with my phone the other day. Evidently my phone doesn't like being severely undervolted. Thank God for nandroid. Also system tuner pro was giving me fits to. So I decided to reflash my rom. I had been running faux kernel with the skyrocket mods. So I wiped data/ reset twice then wiped cache and dalvik twice . Flashed rom and fixed permissions twice. My phone is now smoother then its ever been. I'm not using fauxs kernel either. So the moral of the story is next time you flash or wipe. Make sure you do so a few times. Hope everyone had a great new year! !

Yeah I use to only wipe things once, but the past few roms I've been wiping everything 3 times with no problems that I would run into after only wiping once. I've also read a few people saying that after you wipe everything multiple times and flash your rom..flash the rom again directly after...not sure what exactly that does if anything, but a few do it. If anyone knows what exactly that does flashing the rom twice in a row please let me know. Not possible to have too many good habits if your a flashaholik lol.

Is there a superwipe script like there is for the sensation and the amaze it seems to work great. I always get a clean flash and it works great gives you one thing to do before you flash a rom and a clean install.

Ive never wiped cache and dalvik when flashing roms. Maybe I should. Can I do this now after the fact or would this erase all my data?
When exactly do you wipe dalvik and cache? before and after a new rom install?

I guess if your not having any issues then you don't need to worry about. I always wipe dalvik and cache in recovery before a flash a rom or kernel or a theme.

You are lucky if you don't have any problems. You suppose to wipe dalvik and cache partition before flash/install a new rom. Wipe the dalvik and cache partition in recovery shouldn't erase your data, but if you don't have any problems then I guess you're ok.

Lawl. Funny thread.

(Q) Phone Randomly Decided To Bootloop Today?

Ok I had purchased the ZL battery and have been using it since day 1, however today i got home around 11:25pm. i had put my phone on charge @ 3PM. I just finished my 3rd cycle for the battery so i'd figure its done charging as it indicated it was, and turn it on and now all of sudden constant bootloop out of nowhere.
What could have caused this? it was working just fine before i didn't change anything at all.
I'm Running Stock TW w/Saber Kernel. I had purchased the ZL battery a week ago and ever since no problems, nor did i flash anything at all. I've been on TW way before i even thought of buying the battery.
So what could have caused this to undergo a bootloop session.
I went into recovery and wiped dalvik and cache and still is doing a bootloop. Should i do a factory reset however i have no backup because i have been fine since and I've been on Stock TW figure this wouldn't happen.

This used to happen on my epic if I ever left the battery out too long. I always just reflashed either the rom or the kernel. Worst case scenario you just nandroid and restore data.

Try going into Advanced then format system, data, cache, and dalvik cache.
Then swipe to confirm and repeat this 2 more times for a total of 3 Advanced wipes
If that still doesn't help then follow the same procedure but after performing an Advanced wipe 3x go into Format Data to format your internal storage.

I just did the one click mc2 root restore stock

Seems like you already did a full stock restore. I had the same symptoms, different rom tho. Reflashing the rom without wiping allowed me to boot up normally and with all of my data is intact. FYI for next time.

I said I was on stock and had no nandroid of stock seeing how I shouldn't have needed one. But thanks for the info. I'll have to back it up today.
