[Q] Do I have to flash stock kernel before flashing any other rom? - General Questions and Answers

I want to flash Cyanogenmod 11, but I'm currently running DN4 ROM on my Galaxy S3 (Int.) with arter97 kernel. Do I have to return to stock ROM and kernel before switching to Cyanogenmod?

Not sure what DN4 ROM is. If it's KitKat, then just wipe /system, /data, and dalvik cache then fish your ROM's zip file.
If you are on Jelly Bean, then you will need a KitKat compatible recovery like PhilZ CWM Touch or TWRP, and probably an updated modem. zip file to flash first to your S3.
Then format system and data partitions and wipe dalvik cache, then flash CM11.
If on an older Android version like Ice Cream Sandwich, you might need to install a newer KK/JB recovery and radio, format system, data and dalvik, and flash CM10 Jelly Bean first, then follow the steps to flash CM11 KitKat.
Hope this helps. Good luck!

DN4 is basically a port of the Note 4 ROM (which is KK) for the Galaxy S3. I really appreciate your help, but my my problem is the kernel, because now I have arter97's kernel, but I want to flash CM12 with JustArchi kernel in order to have better performance. On the latter kernel's thread I've read that it's strongly not recommended to flash it on another custom kernel (arter97 in this case), so I was thinking to go back to stock and then flash CM12 with JustArchi's kernel. Is this okay to go like this or there's a better way to do it? Thanks again for your help!

Just make a nandroid backup and try it. Make sure you format system and data partitions and wipe dalvik cache before flashing CM12.
You don't need to go stock first; if you have a custom recovery and the bootloader is unlocked, worst case is you restore your nandroid.
I suggest asking about this in the JustArchi thread too.

(Q) jellybam 1.3 won't flash

Hi guys. Al thou this is my first post I've been flashing my i9003 for a year or so and i've never had any problems until now.
I have an stock gingerbread installed (XXKPQ) that I flashed using odin, kernel version (2.6.35.7-CL709629 [email protected] #1)
Just so you know, I'm from Argentina, and in order to be able to use 3g, had to keep the modem in I9003LUBKB1 version.
I also flashed cf root (by Skin1980) and I'm using CWM v1.80
I get the latest jellybam (1.3) from this post: http://forum.xda-developers.com/showthread.php?t=1972087
And followed the instructions in the official website : http://www.igio90.net/how-to-install/
Just in case you're too lazy to follow the link here are the instructions:
What to do if you are coming from a Stock, CyanogenMod, MIUI, AOKP and any other custom ROM different from JellyBam
-Download the latest revision of JellyBam ROM for your device
-Place the zip into your internal SDCard
-Boot into CWM recovery (Home+Power+Volume up until samsung logo appear)
-Wipe data/factory reset
-Wipe dalvik cache (Inside advanced tab)
-Install zip from internal SDCard
-Welcome to JellyBam!
(I had to wipe the data first and then put the zip in the sd card because wiping the data was erasing the jellybam zip)
The first time I run the installer it got stuck at 50% while installing sony's media player. So i just started the process again and uncheked sony walkman player, it installed "successfully".
When the phone restarted, it was just the old gingerbread, in the about phone panel, it was all the same that before installing jellybam.
So it obviously didn't installed. I can make calls, send and receive messages, wifi is working fine.
So can anyone tell me what am I doing wrong? Do i have to flash a jellybean kernel?, I dont really know hoe to do that but I'm sure there's more than one post around here that explains that process.
If this question has already been posted I'm really sorry, I did search for any post that could help me with this problem but I didn't find any real answer.
I really hope somebody can help me, and sorry for the bad english, I did study the language but it was a long time ago.
Thanks everybody, specially to developers, you're awesome.:good:
I think you should fist flash theJellyBam v1.1.0 alpha4 in order to repartition before flash the v1.3. hope it can help u.

Wiping the data does not affect your Internal/External storage.

First of all thank you for your helpful answer (I clicked the thank you button).
I have cwm version 5 and I have been having the same problem than the OP. I'd like to flash a CM rom before going on to JB 1.3 so my question is, knowing that I currently have an I9003XXKPR 2.3.6 rom, can I flash CM 10 or should I start by a previous version? And, if so, which one?
Thank you for your help.

i think you should start from zero. take a backup of your files, flash a stock rom and then use universal cf root to root your phone. then flash cm 10 alpha 4 and then the jellybam 1.3. that's the way i have flashed mine. i hope it helps.

Thanks for the advice, I flashed a stock rom in the meantime so I am ready to flash CM 10 alpha 4.
Take care

Good luck! i hope you flash it correctly! just read and follow the instructions in the cm10 thread thoroughly so you can avoid any problems.
All custom rom unofficial, not compile, but directly modify our base cyanogen
It is recommended to start on a CM10 origin
Example A3 to A4
KPE> LF2> CF-LF2
Wipe Data / Factory Reset. (MUST DO THIS STEP)
Select the CM10 A4.zip from your SD Card and flash.
Auto rebooted into recovery (if it show error mounting / cache, and cant mount in manually mount and storage, do wipe / cache)
Go to Advanced -> Reboot Recovery
Select the CM10 A4.zip from your SD Card and flash again
Go to Advanced -> Reboot Recovery.
Mounts and Storage -> Format dbdata (you would not find this in CWM so just ignor 6)
8. reboot
You can then flash all based on Unofficial Alpha 4
Just do the basic procedure wipe

If you are on cyanogen mod(CM) then it is obvious that you have an unlocked bootloader and a custom recovery otherwise you won't have a custom ROM. You must backup your current ROM then do the following :
Wipe cache
Wipe dalvik cache
Factory reset
Flash your new ROM.

The usual way, you do all necesarry whipes, and then you install the rom you want. But: no dirty flashesas 4.2 and 4.3have eome architectural diferences (whipe sostem, whipe cache and dalvik, in mounts and storage format both sistem and SD card - better if you back up your photos, music and all media to pc as this deletes everithing you have on in), then connect your phone to PC/Laptop via USB and copy the files of the rom you want, the G-apps and/or kernel

Always after full whipe and factory reset you:
1. Flash the desired rom (it has a kernel of it's own
2. Flash Gapps (they have to be Gapps for your specific rom android version)
3. Flash a custom kernel you like (if you will skip step 3 the rom will still boot up case it comes with it's own kernel, but if you downgrade it's good to flash one case the rom one is mostlikely outdated; and remember that the kernel you flash has to have suport for he android version you flash)
My advice to you if you downgrade is not to go back further than ICS case newer apps will probably have compatibility issues with really old outdated system versions

Hello,
I am planning to flash omnirom on my p3100 as per http://forum.xda-developers.com/showthread.php?t=2512853. Part of the install instructions are installing DhollmenCM kernel.
Currently I am on CM 10.2 nightly. And If i flash DhollmenCM kernel, something goes wrong, How do i go back to previous?
Can CWM nandroid backup get me back to previous?
Will flashing Samsung's original stock rom take me back to previous?
Thanks,
Simon Mandy

[Q] TWRP Carbon nightlyflash fail using install of zip -

Flash of Carbon KK nightly d2lte ROM fails on my VZW (SCH-535) Samsung III using TWRP zip install function. I have tried two nightlies (July 4 and July 13) Any suggestions to get the flash to succeed? I do a clean wipe before proceeding.
I have been using Carbon R 1.8. Is that the last stable release under Android JB 4.2.2 for VZW Galaxy S3?
Does CWM have a better success at processing the zip file contents?

Coming from an older base you need to format system and factory reset according to Carbon's FAQ page. You should also make sure that your recovery is up to date. I'm using Philzs latest touch recovery and updated to latest Carbon KK fro a TW rom without a hitch. Good luck.
TWRP rom flash fails
Thank you.. I am more of a Noob than I realize. I thought I was following the Carbon FAQ - Now I see the 'default' format and factory reset in TWRP does not include system wipe. If I use advance option and select system, data, cache and dalvik cache then subsequent install is successful. KK Carbon is quite impressive! Very responsive.
This closes my inquiry. Thank you.
