I'm currently running a custom Gingerbread 2.3.6 with Semaphore JW1 2.40 kernel. I have root, superuser, and CWM, and I want to flash Cyanogenmod 9.1. I didn't get a specific answer in the CM forums, hoping for better luck here:
My questions:
1. The installation guide says to flash back to stock if already running a custom ROM, but what should I flash? Since CM9.1 is a ICS based ROM, do I need to flash a 4.0 ROM?
2. Should I flash the kernel to a stock one as well? I've seen a general guide in the CM forums saying to start from stock and Semaphore gingerbread based kernel, and then just run update.zip from CWM. On the other hand, I've also seen a contradicting thread saying that CM9 is only compatible with ICS kernels and using a GB kernel will cause a bootloop.
2. I also have the filesystem converted to ext4. Do I need to convert it back before doing anything?
3. Does CM9.1 installation come with its own custom kernel? If not, are there specific kernels that can be used with CM9.1 or is any Android 4.0+ kernel usable?
Hey
I think you should revert back. Flash stock gingerbread with odin, install sempahore kernel and flash the rom you want(I would actually recomend cm10, Its very stable). Goodluck!

how should i install miui over cm7 rom ??? Should i go back to stock or is it ok to use CM7 cwm recovery ???
You can just use the recovery that came with CM7, no need to flash to stock.
*Get Chance and Luck*
And what if i want to go back from miui to cm7? Should i have to go back to stock or miui cwm wil b ok to flash cm7 ?
again no need to flash to stock...as MiUI is based on CM7...only flash to stock if you are going to flash to non-CM7 (MIUI) rom.....
also flash to stock if you are stuck in bootloop....
To follow up / add on to what vinyl2cool said, you can think of it this way:
MIUI, CyanogenMod, and ICS are all based around CyanogenMod's take on Android. It may take a couple of reflashes in CWM to move between them, but they will all work together, no special steps (e.g. Odin or Heimdall) needed.
Any rom with a 3-letter acronym starting with J or K (e.g. KK4, JVZ) will allow you to jump to another one from CWM. It may take a couple of preparation steps, but again, you shouldn't need Odin or Heimdall.
Pretty much the only time you will need Odin or Heimdall for rom flashing is if you're jumping between those two camps. (That's not to say there aren't cases where Odin/Heimdall have other uses, but that's another topic for another day.)
"DO NOT try to go to any CM9 or CM10 based rom from the Samsung ICS rom/kernel. Sure shot BRICK"
If I flash Hydracore Kernel on my stock ICS ROM is that still unsafe to flash CM9/CM10 rom?
If I on custom ICS rom with Hydracore Kernel I can directly go flash CM9/CM10 rom?
yes you can flash CM9/CM10 Roms (if your coming from stock or custom ICS Rom) if you have a safe kernel already, BUT....
for extra and safe measure.. I would recommend you make a nandroid/TB backup and then do the 3 wipes before you flash the CM9 or CM10 Rom(again if you have a safe kernel already installed okay?).
the reason why I'm trying to advocate this wipe first is for you to just have a clean and safe installation of the said ROM. Though most says it is not necessary doing the 3 wipes anymore, but on my personal experience... doing the 3 wipes first (before flashing the new ROM), usually skips installation problems that might occur when jumping from one Rom to another.
imho....
I apologize if this has been asked several times before but I want to be 100% sure I'm doing the right thing since my Note currently has brickbug. When I first got ICS via a Kies update, I had to do a stock wipe from Settings because apps were crashing and freezing. As far I can tell there hasn't been any permanent damage. I've since done another OTA update via WiFi.
I want to go from Stock ICS 4.0.4 to ParanoidAndroid JellyBean

Then can I use CWM to flash latest build of JB ParanoidAndroid from http://goo.im/devs/Utacka/n7000?
Also will this cause the Yellow Triangle?
what i did was flash hydracore kernel with mobile odin then flash paranoid android as described in its own thread.
also make a full wipe AFTER flashing hydracore from CWM

Flashing the PhilZ kernel via Stock Recovery wouldn't work? That seems to be the most simple method. Does HydraCore have advantages over PhilZ?
it should work too. i just write the method i used and of course it is not the only method to do it.

Ok, I have PhilZ on my Note now. But still have stock ICS. The ParanoidAndroid threads say "Make sure to run CM9 or an AOSP-based ROM : FLASHING FROM STOCK ICS OR ROMS BASED ON STOCK ICS WILL RESULT IN A BRICK!"
So does that mean I can't just flash HydraCore and then flash ParanoidAndroid? Do I have to flash a CM9 ROM or other AOSP ROM before ParanoidAndroid? Also is PhilZ kernel compatible with ParanoidAndroid?

I did exactly the same recently (but I went from stock to another ROM which had the same message, not ParanoidAndroid) - ran philz then the kernel should be safe which means you should be safe to flash to another ROM. That brick message on the thread I assume only applies if you are running a stock ROM with the stock kernel. If you want to be sure check in Settings>About Phone>Kernel Version - see thread here http://forum.xda-developers.com/showthread.php?t=1857556.

My advice is dont use Philz kernel for flashing ICS to JB... becz i read somewhere no unique Philz kernel to supports for ICS and JB
I had done many time ICS to JB (like Kingdroid RAM to Paranoid JB, Paranoid JB to STOCK ICS etc. ) no issues...... because of I used Hydracore 4.3b kernel..
thanks

The Kernel version looks the same to me as it did before I went to PhilZ. I rebooted into recover to make sure CWM is on there, which it is. And I installed a custom boot animation to make sure that worked, and it did.
Sounds like I should go to HydraCore Kernel first since it's compatible with TW ICS and JB then flash ParanoidAndroid ROM.

Thanks, sounds like my best course of action is to flash HydraCore now and that way I can test various ICS/JB ROMs.
Since my original post I have:
Flashed PhilZ-cwm6-XXLRK-XEU-2.7-signed kernel in stock recovery to get original root and safe kernel.
Flashed GL_HYDRACORE_v5-4_STD kernel because I thought that's what I needed for PA.
Flashed pa_n7000-2.51-24OCT2012-192916 and followed instructions from Hydracore thread which said to flash kernel after done flashing new ROM and gapps. However - PA would not boot after that. I also tried pa_n7000-2.52-29OKT2012-101254-Utacka this way. Same problem.
So I decided to flash pa_n7000-2.51-24OCT2012-192916 this time but without changing the kernel. Booted fine this time and my phone flys now! Way faster than Stock ICS 4.0.4. It's nuts that official ROMs, by comparison, are so slow.
So I'm trying to understand how to know which kernels will work with which ROMs. So I've been reading the various stickies and this thread in particular - very carefully. And I see the part about "WARNING: Do NOT use the below listed kernels for any CM10 build dated October 3rd or newer because your system will not boot.". I assume this why I was having issues after flashing Hydracore immediately after PA? And if I'm understanding this right, I could use the new HydraCore v7 with this PA JB ROM I'm on now? Is that because of this new MALI driver?
I did an EFS Backup after I did the original PhilZ kernel install but I never did a Nandroid backup while I had stock ICS. Should I just do that on any functional ROM now to make sure I have a full working copy of something to get my phone restored if something goes haywire? Is that the idea?
Also a lot of people seem to recommend flashing ROMs using PC ODIN. Is this considered safer or less risky than using CWM?
ParanoidAndroid JB imilka build has been great - but I noticed a few annoying issues:
1. WiFi signal seemed a lot better in Stock ICS than it does with PA. My signal is always "Poor" in my bedroom and I'm not very far from the wireless router but when I'm in the living room - it's excellent. Is this to be expected or is there something I can do about that?
2. Audio issues - sometimes I have to play with the volume to get speaker phone working after hitting the on-screen toggle.
3. None of the Voice Input stuff works. It just says "Initializing" and then "I didn't catch that". Also described near the end of the PA thread but haven't seen anyone reply with a fix.
4. No timer/stopwatch built into clock app. Can someone recommend a good app?
5. When I change the Slider shortcuts under Settings->Interface->Lock screen, they don't save. It always go back to default - Camera, Google Search and Unlock options only.
6. Looking for a nicer clock widget. Can someone make a recommendation?
Just wanted to point out that I love that it automatically had the StraightTalk APN configured for me. I know you're probably thinking - yeah so? - but I'm relatively new to android ROMing - just been lurking for awhile - so it was a pleasant surprised.
Any help would be greatly appreciated.
Hi guys,
I am new to this forum and to flashing custom roms in particular. I have read a lot of stuff about the eMMC chipbug and how to avoid it. I want to install pa_n7000-2.53-05NOV2012-125144-Utacka from stock ICS 4.0.4 with this kernel: speedmod-kernel-n7000-ics-k3-15-Odin. Is it safe to flash the PA with the CWM of the speedmod kernel or should I go back to gingerbread as I have read on some other fora?
Thanks in advance!
yes its safe. speedmod is a safe kernel

So all I have to do is reboot in cwm recovery, and install PA from sd card, then install Gapps, then wipe/factory reset, wipe cache and wipe Dalvik cache and it should work 'without' risk?
yeah.. first wipe data /factory reset
wipe cache
wipe dalvik
format /system
then install zip from sd

want to be safe before flashing PA
hi guys
i m using rocket rom. now i want to flash PA 2.99
i m concerned about this warning...Make sure to run CM9/10 or an AOSP-based ROM : FLASHING FROM STOCK ICS OR ROMS BASED ON STOCK ICS WILL RESULT IN A BRICK! - You're warned!
what should i do..?
RR version ? It has a safe kernel so you are good to go. You can ignore that warning

YES it has one of philz safe kernels..
so what i think is its totally safe to flash a new rom if u have a safe kernel. Am i right???
what if i flash a kernel(safe one) which is not compatible with my currrent rom....is it risky or my device will just not boot or anything else.....??
I have an untouched Note running stock ICS 4.03 -- Kernel 3.0.15-N7000XXLPY ...). I'd like to be able to safely flash a custom ROM, avoiding the brick bug. I've been digging through a lot of threads, but some uncertainties remain.
Here's what I'm about to do: I'll get the Philz kernel matching my current rom (this would be PhilZ-cwm6-XXLPY-XEN-v3.99, right?), boot into stock recovery, flash the .zip from the sd card, and boom, I'll have a safe kernel with root and CWM to flash any ROM from. Is this about the right plan?
2 more specific questions:
1. The matching Philz kernel was posted under the headline "Update to all ICS 4.0.4 kernels from 3.71 ---> 3.99" in the Philz kernel thread. But I'm running 4.03. So is this the right kernel for me?
2. Will the ROM I install after that have to match the Philz kernel in some way? I'm thinking of getting the Official CM 10.1 from the nightlies thread.
Thanks so much!!
That's the right plan
1. The correct rom is found under rom build which is the last in the section where you found the kernel version. The 4.0.4 also works with 4.0.3 so it's ok.
2. No the new rom will install a new kernel. Philz won't work with cm as philz is Samsung kernels repacked for safety and recovery..
Thanks, man.
Just to clarify: once I'm done flashing CM 10.1 from the philz kernel, I will no longer be running the philz kernel, but the CM kernel? Is there a reason why I can't go directly to flashing CM 10.1 from the stock rom and recovery, skipping the Philz kernel part (if I refrain from wiping in the stock recovery, when the faulty stock ICS is still on there)?

Correct me if I'm wrong but I don't think you can flash CM 10.1 from stock recovery.
Philz kernel comes with CWM recovery which provides more functionality than the stock recovery.
For example you can do a nandroid backup (basically a snapshot of your current phone system) so if you ever flash a rom that you don't like or something screws up, you can just restore your backup.
I think your first priority should just be flashing a safe kernel (Philz) and only then should you be looking into flashing custom roms.

Custom rom can only be installed using Cwm
OK, thanks for your help guys. I just flashed the Philz kernel following to the instructions and all is well. CWM is working, and I appear to have root access in my old stock ROM.
But in the phone info, the kernel version is unchanged. It stil says: "3.0.15-N7000xxlpy-cl474507 [email protected] # 3 SMP PREEMT Fri May 4 04" -- which is the exac same thing it said before I flashed the kernel.
How can I verify if I'm actually running the safe Philz kernel now?
PhilZ Kernel are only modded kernel, so they aren't change and stock kernels. And so you won't see a description made by PhilZ but only the normal information of the original kernel.
To be sure: boot into recovery and check the CWM version and compare it with the infos in PhilZ thread.
But you told already that you do not have the stock recovery, so everything is ok.
Thanks ThaiDai. The fact that I had moved successfully from stock recovery to CWM was already a strong hint that things worked out.
I wanted to make extra sure, so before flashing the first custom ROM I went into CWM, made a backup of the stock samsung, and then took this script right here to examine the operating kernel (boot.img in the backup folder) for the brick bug: http://forum.xda-developers.com/showthread.php?t=1807995 -- the script returned that the kernel was safe.
So I went on to flash CM 10.1 and I'm a happy camper now! This forum is a great place for getting help, you guys are terrific!
its been a long time since i flashed a custom rom on my phone.... so yes i lost the intelligence and confidence of doing it again...
im on rocket rom v12, running hydracore nirvana n4 OC kernel, since i find my current rom boring. i think its nice to flash a custom rom in this case utacka's paranoidandroid rom,
can u guys guide me into flashin paranoidandroid rom safely pls??
PS. dont suggest anything that contains the use of PC odin because I DONT HAVE A PC, i have rooted, flashed custom rom/kernels on my note without the use of a pc, just wifi, my note and me
Nirvana is a safe kernel. So you can download the PA rom. Boot into recovery. Perform wipes and formats. Install the rom. No preparation required.
Also, don't forget gapps.You don't need to flash gapps for touch wiz based Roms,but for aosp and cm and aokp you need to flash gapps.
