[Q] How to update your ROM.

Hello guys, I would like to know how to update my ROM using dalvik cache? I have Foxhound ROM 0.3 and i would like to install the 0.4. Can anyone help me ?

Hi Mate
You don't update using the Dalvik Cache. The Dalvik Cache is just something that is best to clear before an update.
In order to flash a new ROM there are a few things you need to have set up on your computer and phone and they are well detailed here:

Read the above thread and find out what has already been done. I think your phone will be Bootloader Unlocked and Rooted already. If so flash the latest Clockwork Recovery Mod CWM and then just download the ROM you want and store it on your phone. Once done you will be able to use the above link to easily write it to your phone using CRM and the Flash Update from SD Card Option.
Hope this helps.

Ummm. he doesn't have to read that thread..
Just simply download the ROM
Put it on your phone's storage
Boot into CWR
Wipe Dalvik and Cache
Flash ROM
[OPTIONAL] Flash Kernel (if you used one a custom kernel)

If you flash another rom, will your apps be wiped as well? And if you flash an update from the same rom? Just back-up with Titanium or? Thanks.

Apps are never wiped unless you wipe data/factory. Yes use titanium

This is a noob question but i'm still very much new to this.
I have aokp 10/8
and i'm running one of simonsimon's kernels
and i need a guide on how to update my kernel to Jellyboot5 and how to update my ROM from the 10/8 nightly build to the 10/17 stable/nightly build. Someone please provide me with a quick explanation on how i should do this. What should i clear? and how do i flash it and which files do i flash first? All help is greatly appreciated. Thank you.

For kernel you flash it normally ..like you flashed it the first time
For Rom you flash it from recovery and only wipe cache and dalvik cache ..thats it

same way as u flashed 1st rom
flash kernel
wipe data/cache/dalvik
flash rom
reboot
njoy

First go into bootloader
Flash kernel
Then enter recovery without doing any reboots ....and flash the new Rom but before wipe cache and dalvik cache

When you install a custom rom install the kernel provided with that rom and read the instruction on that specific rom how to install

am doing all the steps mentioned, and am still on locked boot loader.

thats your problem you cant have custom roms on locked bootloaders.

when you install other custom roms you should follow those steps
factory reset
cache partition wipe
wipe davlik cache (cwm>advanced)
(i also format system but its optional)
install rom zip
reboot... i do this and i have never stuck on sony's logo

[Q] A little help here

So i'm a newbie here. I've only installed one custom rom so far. I have an R800i with unlocked bootloader, DoomKernel v14 and Auroraplay v0.8. The thing is I want to install Lupus GBv8 kernel and the newest AuroraPlay, but i'm not sure what the steps are. Do i have to reinstall the original .ftf again then flash the kernel in fastboot and then the ROM?

That's the way to clean install (Recommended by me @@!)
Ỏ u can just flash the kernel. Then boot into recovery, and wipe everything. Last, flash the ROM

Flash firmware that have unlocked vendor partition, so you can have 600MB data partition (and you should do only once)
Power off, flash kernel without booting to OS, wipe data and system, and install new rom.

Stuck at Google/flashing the wrong kenel

OK. I flashed the wrong kernel on my new Nexus 7 (2013). My stupid, I flashed the kernel (franco) for the old Nexus 7 on the new one.
Luckily, I can still access bootloader and recovery (TWP). Now it's stuck at Google (again, I can still go to bootloader and recoery).
Where can I find the stock kernel that I can use? Or Can I flash a custom kernel?
Thank you in advance and I appreciate every comment.

Have you considered trying this which will return your Nexus 7 to its original factory settings with a stock image? I haven't used this method but it may get your tablet working again. Also, for future reference, you should always make a nandroid backup before you flash something new in case you run into problems like this.

Wiping the cache/dalvik cache usually works for me when it would hang on the boot screen after a flash.

I did it but nothing changes

Do you have a ROM installed?
Try restoring to factory settings, reflashing a ROM, and then flashing the kernel. Wipe cache/dalvik once you're done and see if that works.

Try flashing the stock rooted ROM here.
To restore to factory settings, go to "Wipe" then slide the slider at the bottom of the screen.

Thanks cyberprodigy and Username invalid for helping me.
I fixed it.
After flashing 2 custom kernels (all of them were said to be completed install) but I was stuck at Google.
So I tried to flash a stock kernel (I downloaded it from here, sorry for hotlink-ing from another forum: http://droidbasement.com/asus/razor/flo/sys-backup/jb-4.3_ota-full_n7_razor-flo.zip). I will also uploaded the stock kernel file extracted from that link in case somebody needs it but doesn't want to download the whole Stock ROM.
The file extension is .img, so for people not knowing how to flash this file, use this command
"fastboot flash boot <the file name.img>"
Thanks again.
Here is the llink to the stock kernel for N7(2013). it's 16Mb so I can't attach it.
