[Q] Custom ROM and 4.0.4 question

I updated to 4.0.4 last weekend with the leak. I now want to flash GummyNex to my Nexus. Must I flash back to 4.0.2 before I load GummyNex or any other custom ROM? Or can I just flash the custom ROM on top of the 4.0.4 update?

No just wipe data, dalvik, cache and flash the ROM you want to flash with gapps (if required) and kernel (if you desire to)

Thanks! I appreciate it. I've never flashed a custom ROM...just the unofficial OTA's. The kernel is a totally separate file correct?

Yes, you can flash kernel after flashing the custom rom, but keep in mind that some kernels only work for a specified build.

Yes kernel is a separate file. Some ROMs will include a kernel with their ROM (mostly stock kernel but it could be different).
So if you flash a ROM (or a update), flash the kernel update again because flashing the ROM zip will override your kernel.

Updating to ICS roms

Hey everyone,
About 4 months ago when I got my new Epic 4g touch I rooted the phone with autoroot and installed calkulins rom which I now have at version 2.6. I am also using an ICS theme. What do I now have to do in order to get the newest modem and custom ICS roms installed on my phone? Since autoroot is no longer functional I have heard that I will have to install the stock rom and modem on my phone and then use odin to install new modems.... Is this the case? Does anyone have links to stock roms and modems I should use before I proceed into using Odin?
Thanks!

You have few options:
1. If you want latest stock rooted rom just flash sfhubs one click FF18 rooted rom from this thread:
http://forum.xda-developers.com/showthread.php?t=1721229
2. If you want any of the custom TW (stock based) roms read thru threads, see which one you like most download the rom and copy to your sd card.
Boot to recovery. Wipe/factory reset (you're on GB rom and you're not risking to brick your phone) and apply zip in recovery.
Rom will flash kernel as well and you will have rooted ICS rom on your phone.
Download CWM modem zip file from sfhub's thread and flash it in recovery as well.
3. If you want AOSP/AOKP/CM rom just read the installation instructions in OP and follow them.
If you have more questions, ask....

Thanks!!
So sprint plugged the autoroot feature but I am still able to download any ICS rom on my current setup (after full wipe) and install through my CWM and it will work? I am on the EK02 modem, I am able to upgrade to ICS modems without using Odin?

if you have custom recovery you can flash CWM modem zip from sfhubs tread in recovery.
If you don't have custom recovery use sfhubs autoroot package to flash EK02 kernel with CWM recovery and than flash rom and modem in recovery.
Sprint din't include anything for us. It's all done by a great developer sfhub.

With Sasmung devices and their ODIN support, you aren't really required to have root to flash anything. In other devices(HTC), you need to have a exploit to root them so that you have Read/write access to certain partitions that you wouldn't normally, thus allowing you to flash.

How do i go back to stock rom??

i installed CM9 alpha6 and its slower then stock rom
i want to go-back but i dont know how to..
plz help

You can Odin el29 one click sfhubs, or install the safe kernel from agat version 2.3 and flash back your nandroid if you made one. Its safe with that kernel.

Which recovery to use with JB?

I haven't gotten my way entirely around this specific phone when it comes to recoveries and such. My sister owned this phone sometime before me and while she had it, I rooted it and installed a safe recovery. I later flashed CM10 on it, but earlier I flashed a rooted version of the JB leak, and wanted to know what recovery can I use with JB so I can flash other Touchwiz JB roms?

There is an Agat repacked FK23 thread but there are known issues. You can check out that thread in the dev section. There are some other repacks in there as well.
As of right now, the recommendation is using el26 cwm as the go to recovery for flashing anything while on a JB TW build.
So, in short, you'd:
1. odin el26cwm
2. either do a battery pull or long press and hold power+vol up (as normal) to get straight back into recovery (rom will not boot now)
3. Flash the JB TW rom
4. Flash the JB stock recovery.
5. PC odin the JB modem (if you're currently not on one)
If you're going to flash any aosp/aokp builds, those thread OP's have detailed suggested instructions.

Safe to flash kernel?

Hey I have kernel 3.0.31-310959, and I was wondering if it was safe to flash to perseus kernel?
Android version 4.1.1. Build: JRO03C.N7100XXALJ3
I tried to flash the perseus kernel when I was on a custom rom and it wouldn't boot so I had to recovery restore back to stock.
Thanks!
