Hi,
Currently I am still on GB CheckROM v5 with franco kernel 6.Never flashed any ICS ROMs before.Now I would like to finally upgrade
So before flashing ICS ROM,i would like to double comfirm the steps which i have read
1.)Boot into recovery and install GB abyss kernel 4.2
2.)Reboot recovery to abyss kernel(Can i restart phone?)
3.)Wipe data / cache / dalvik
4.)Flash ICS ROM
5.)Reboot phone
Side Qn,I have GB apps that is not updated to ICS compatibility, if i try to restore them,will it cause conflict?
Thanks!
If you're on a rooted GB, you don't need the Abyss step.
Also, when you move to ICS, using NoteCore, SpeedMod, any CM9/10 kernel are 100% safe to flash from.
ROM recommendations, CleaNote, KingDroid 7.1 and Asylum 20 (CM9-based) are my favorite.
Have a look to 'ROM Switching' on my signature.
Hi dr.ketan
I have read yr ROM switching guide.Great guide btw
I would like to clarify that the steps are for stock ICS ROMs?
cause I would like to flash from checkrom GB straight to criskelo's ICS V11.2(Post #2 says flash abyss then to criskelo ROM).I do not have to flash stock ICS ROM first correct?
Thanks!

Thats tutorial is right..
Just flashing the rom from franco kernel..
But if u're not sure with franvo kernel n want follow all the tutorial u can do it..
2.reboot recovery to abyss kernel thats mean had u flash abyss kernel u must reboot recovery..
U can do normally reboot but u will get stuck..
Don't be afraid,u can use home + volume up +power button...

As far as I know the LPY was an issue and as long as you don't wipe data/factory reset in that one, than it shuouldn't be a problem either...I'm on LQ2 and have been on LP9 I think and I even accidently wiped data in LP9 and nothing happend. So you should be safe as long as you're not on LPY and like get the LQ2 or LQ3 version.
ICS is safe with a safe kernel i.e. CM9,franco kernel etc which are clear of any wipe bug present in the stock ICS kernels.Hence, the CM9 nightlies,ParanoidAndroid and other ROMs which utilize to CM9 kernels are safe.
Alteratively, you can also flash to GB and then flash a ROM with an unsafe kernel and then flash a safe kernel via PC Odin.It's recommended to go through flashing GB as it reduces risk.However,do this at your own risk

According to my understanding/knowledge none of available ICS official firmware/ROM is safe. Use safe kernels and ROMs mentioned by warfareonly.

Mostly right. Any AOSP kernel is safe - eg CM9. But then you don't get touchwiz, if you want that.
There are a few Samsung based kernels which have the brick bugs removed. They are probably safe - there have been no bricks with them that I know of.
NEVER wipe or format using stock ics kernel (whether from cwm or within android) if you are rooted.
To be completely safe, either use Odin or from a gb kernel. If you are rooted you don't have to flash a full gb rom - just flash abyss 4.2 and then reboot to recovery (do not reboot the device). Then wipe and flash a cwm flashable from from abyss recovery. There is no danger of the brick bug provided the wipes are done through the gb recovery.

Yes,you are right. The kernel must not be official,has to be custom(and not based on lpy) to be safe.

I am on stock DDLP8 with stock kernel. I am planning to flash paranoid android. Can anyone confirm if following steps would work properly:
1. I flash franco kernel via PC odin.
2. Flash Paranoid Android using CWM.
Or shall I resort to the longer & safer route of going back to GB first & then flashing paranoid android.
Read the instructions given on the Paranoid Android ROM thread.They clearly state to go back and flash from a GB rom...Here, I've posted the info for you
--->DON'T flash FROM ANY SAMSUNG ICS OR ROMS BASED ON SAMSUNG KERNELS
--->Flash any stock GB rom with odin / or any GB kernel ,root deviceand reboot into recovery once again before flashing this
--->Install Rom: http://d-h.st/agf 119.46 MB
--->Install HYBRID Gapps: http://tjohansson.is-a-geek.com/file...0511-fixed.zip
--->Wipe caches, factory reset is a must if you're coming from another rom than CM9
Next time, read.Safety always
hey
im currently running rooted ICS 4.0.3 XXLQ2 that i rooted with the CF-Root kernal.
My question is, is there an Abyss kernal that i can flash over that with ODIN so i can use it instead?i hear that abyss is safer than CF and you can actually install custom ROMs from it. Also, I'd usually find this info myself but everything i can find about it is a bit confused so i would like a simple yes or no answer
Cheers
Abyss is a GB kernel. DO NOT use it on ICS!
Abyss Note kernel is not compatible with ICS.
ah right OK, some folk are saying that it was compatible with ICS, so I take it my best bet for using custom ROMs would be to flash back to stock GB then flash Abyss, yeah?
EDIt: i meant to say, are there any safe custom kernals out yet for ICS that are ROM flashable and wipe-safe?
"ROM flashable and wipe-safe?"
???
once you have a rooted rom with a custom recovery like CWM then you can flash most kernels. Some kernels arn't compatable with some roms but the thread will usauly indicate which roms work best with the kernel.
I most cases when you are flashing a new ics rom it is not safe to do a full wipe.
I have just upgraded to rocket rom v6 i did not full wipe when flashing but once the rom was up and running i just go back to cwn and do a full wipe, seems to work for me.
Hope this gives you some info on the matter.

what i meant by wipe safe and rom flashable is that im not gonna brick the phone by doing a factory data wipe or by flashing a custom rom, from what i have read if you flash from pretty much any ICS kernal to a custom rom its an insta-brick
You had the right idea at first. Some ics kernels (eg Franco, cf and speedmod) are probably safe to wipe with. I say probably because they have had the emmc wipe command removed.
But to be guaranteed, reboot into cwm (assuming you are already rooted) then flash abyss 4.2 GB. I use the red version so I can be sure I am flashing from GB.
Then reboot to recovery. Do not reboot the phone - it will not work - but it will happily boot to recovery. You are now in GB recovery and can wipe with no risk of brick bug at all. Flash any cwm flashable rom. Just make sure you had copied it to your SD card before you started this process!!!

Hi everyone.
I have a very general question in terms of installing ( flashing ) all the ICS ROMS from stock or custom ICS ROMS.
for example let's say criskelo , kingdroid , rocket , CM9 , paranoid ROMS are poplar ones out there, for all the roms the best way is to flash first abyss then if we are upgrading from the same rom there is no need to wipe anything, if we are coming from another rom we wipe factory , cache and dalvik cache. then we flash the rom.
does this work for all of them?.
thanks.

In general, the method is same for almost all these ROMs. However, each custom ROM will have its own installation method as put down it its OP thread, which we definitely need to follow, to avoid bricking / other problems with our device.
Also, since stock ICS Kernels are unsafe, it is recommended to downgrade to GB, which is safe & hence Abyss Kernel comes in picture. Once on GB you can then flash any custom ICS ROM + Kernel. But if upgrading from a safe kernel, no need to have Abyss. Pls. read sticky thread for details on safe & unsafe Kernel

So when some threads say first go back to GB means first flash abyss, right?.
BTW now that I have criskelo v7 and then I wanna go to criskelo v9.1, first I install abyss then without wiping anything I must flash the ROM. right?.
thanks.

Hi,
im not pretty sure how to flash safely from my ICS to JB (CM10).
Im on RocketROM ICS XXLPY v3 with the Notecore Kernel.
In the developer threads there is mentioned that you have to upgrade from
CM9 or something like that.
I just want to get sure, before bricking my note .
Hope somebody can explain to me which methods are safe and which not.
Thanks !

Safe methods:
- Flashing from GB kernel ( for CM9 )
- Flashing from custom / non-stock ICS kernel that had the format command removed
- Flashing from CM9 / CM10 kernels
Brick methods:
- Flashing from anything ICS that came from Samsung
Simply follow the instructions in the thread and you'll be fine.
Check if Notecore kernel is "safe". If it is, you're ready to go. If it's not, you need to flash safe kernel first, and then go for CM10.
If you're afraid or anything, you can always go the long way: stock GB via PC Odin > root > CM9 > CM10, although we should really stop using this method now because devs put a lot of work so that we won't have to do it like that.
Okay.
My way, i would try it:
1. Flash AbyssKernel 4.2 over my ICS RocketROM ICS XXLPY v3.
2. Reboot the recovery
3. Flash CM9 and GApps
4. Factory Reset/Data Wipe
5. Reboot
6. Reboot in Recovery
7. Flash CM10 and GApps
8. Factory Reset/Data Wipe
9. Reboot
The only part, which makes me unsure is "Flashing from anything ICS that came from Samsung". You mean the kernel or could RocketROM brick my note cause its from a samsung firmware ? Even if i flash Abyss before ?
Sorry for asking again, but the Note is a expensive device and I dont want to go back to my Lumia 900
Thank you !
This is my metod. All working good on my N7000
My method:
-Flash CM9 kernel with PC Odin
-Boot into CWM and flash CM10+gapps
-wipe/factory reset and wipe dalvik
done
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

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.

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..

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

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.....??
