[Q] Installing custom kernel = boot loop - LG Optimus 2x

Hello, when i try to install custom kernel i face a boot loop. I only tried with v10, not tried with v20 though. Tried 3 different kernels and the same. Why is that? It just doesn't work.
And can you tell me some working custom kernel for v20l to try?
Thanks in advance.

What rom are you using?
For myself, usually its an issue of partition beinh ext3 or ext4 that will cause bootloop. I will usually try back2ext3 from paul or ext4 converter.. either one usually fix the bootloop depending on kernel requirements.
Cheers!

Not enough details. Which kernel?
On total stock ROM or on custom stock based ROM?
We are talking about kernel do don't use what is mentioned just above, it will wipe your all system.

I had a boot loop problem after installing a custom ROM based on stock ROM. I didn't wipe the phone before updating to custom ROM. After recovering the original ROM, I wiped the phone from CWM and then updated it and all works well now.

Well i have tried Neoblaze, HorsePower, Spica. I don't wipe after/before installing.
I om on stock rom. Then i must go back with back2ext3.

After installing the kernel try wiping cache and dalvik and see if that helps.

that's your problem, you have to wipe cache and dalvick cache after flashing. hope this can help

Thanks you, im very happy - working now. Flashed HorsePower.

My o2x won't boot when I apply a oc/uv kernel

Hi all
I possess one o2x at present there 1035.21_20110218 on mckr12 Roma fr16 beta 4.
I noticed that when I flash a capable kernel oc / uv, my phone stuck on the log's logo...
Anybody has already met this problem?
Thanx
No but if you reflash the rom it will remove the new kernal and put the original one back on and you will keep all your apps etc aswell
I have this problem too, i flash the new Fr17 & Fr18 mcr can't boot. If i just flash the older Fr16 kernel, it booted...............
soo. no way to have a uc/uv kernel on my o2xs ? :'(
If you flash vork then it won't work cause it was meant for CM7
just reflash back the ROM in recovery
Back to Stock Rom.
Try to back to stock rom as said dusitmon123, then Wipe everything, and reinstalling custom rom will work...

Should there be a quote "Installing System Files..."?

No as it is kernel it doesn't concern system partition, except for writing some files for example in init.d folder. Perhaps the dev forgot to put the info line.

the latest version for CM 7.1 stable support is 05112011, above that version is not CM 7.1 stable version
Thanks everyone. I tried everything, and that´s right, i don´t think Cn7.1 stable supports the latest swiftextreme. I´m now on Miui android 1.11.18, it runs very well.Battery life is very good.
Thanks

Phone restarting after flashing to Stock GB ROM

Apologies, but since I am a new user, I was not allowed to post in the thread in developer section.
I had bought a pre owned phone, on Rocket ROM (GB based), however as S-Pen apps were not working I decided to go on the stock ICS rooted way.
I followed the instructions here:
http://forum.xda-developers.com/showthread.php?t=1424997
I had downloaded the stock INdian ROM
N7000XXKK3 ------ 2.3.5 2011 November------ N7000ODDKK1 ------------------------India -------------------------Download

I followed the steps, downloaded Odin, and put the TAR file in PDA section, and flashed. All goes fine without error, on the phone it says everything is installed successfully. However after the process the phone just keeps restarting after the Samsung logo.
Have I done anything wrong here? How do I rectify the mistake and get my phone working
Did you clear cache/dalvik or do a wipe in recovery menu ? Looks like it's stuck because of leftover data from previous rom

Umm, pardon my ignorance as I am migrating from an ancient Nokia device.
No, I had done no such thing, no backups too as I just had it for a few days and no data so to speak of.
Should I be doing a wipe in recovery menu? And doesn't flashing the device, formats the memory too?
I think it should, but for some reasons it does not. To get rid of boot loop, go into recovery and clear cache. Should boot properly then
Also, avoid doing a factory reset on stock ics. If clearing cache wont help, i'd suggest flashing gb stock rom, doing a wipe and then upgrading to ics as wiping under ics has caused people a lot of troubles.
Yes you should do a wipe of cache memory and dalvik cache. That is availible from recovery menu. And no they arent allways formatted when flashing a new rom.
To go into recovery, do this.
Device off > vol-up+home+power. And now you are in recovery mode.

Thanks, I had read up how much ever I could, and am pretty wary of the emmc bug. Thats the reason I am flashing to a GB based stock rom, and then the ICS stock rom.
The error I got earlier is by flashing to a Indian GB Stock ROM, should I yet clear cache memory in the recovery mode?
A little bit of googling tells me I should be flashing to a ROM with multiple files (different ones for PDA, Modem, CSC etc) hence I am also downloading the stock Europe based ROM. Now the query is would the stock Europe GB ROM, cause any issues to a Note bought in India?
Edit: I wiped the cache partition in recovery mode, but the bootloop persists. I will try flashing to the Europe GB ROM and update.
Thanks, folks was able to install the Europe stock GB ROM, which I later flashed to an Indian stock ICS ROM. I have rooted the phone by a very helpful guide by Dr Ketan, however I miss some of the functions available to me on the rocket GB based ROM. Especially an option to have a data on/off option in quick notifications.
What is the purpose of rooting the stock ROM? Can I delete the bloatware that comes pre-installed on the stock ROM, once the phone is rooted? If yes how?
Any safe custom ICS ROM's you guys recommend? If I am right the correct way right now seems to be to flash a safe GB based ROM everytime before you flash an ICS ROM? Correct?
Last but not the least, thanks to the folks who replied and guided me in the thread, XDA is a very resourceful place, if you search it thoroughly.
About notification toggles - they are available in some roms, in others - not.
As far as rooting is concerned - yes, you can delete almost all the bloatware. There is a thread with APKs that are safe to remove - check it out and feel free to delete everything you won't be using. How ? Simple file explorer with root capabilities will do. Here's the list, thanks to pulser_g2:
https://spreadsheets.google.com/spr...1gdDJRekl4QmkyNmIzUmRvX2h3UDVkQXc&output=html
Safe custom ICS ROMs - I'd say go for CM9. For me, AOSP is the only way to go with Android. If you want TouchWiz based roms, however, can't really help cause i've never used them - there are plenty in development section though.
Nope, you don't need to flash GB ROM everytime. The problem with wipe affects only stock ICS roms ( so with stock-kernel based roms from Samsung, yeah, that's recommended ). But if you're going to flash/change/update roms like CM9, Criskelo etc. there is no need to go back to GB everytime.
Hi i was on ICS stunner and flash via PC Odin Stock GB rom.

Download abyss from the following site:
http://downloadandroidrom.com/file/...rnel/AbyssNotekernel42CWTouchOriginalLogo.tar
Flash the file with PC odin then reboot into abyss recovery. You can then do the wipe.

Help..stuck on bootscreen after flash!

Advice please...stuck at bootscreen! (followed instructions in crash thread s follows
1. Was on rocket rom v10 with notecore.
2. Flashed abyss
3. 3 wipes + JBroid cleaner
4. Flashed crash 8.2
5. Rebooted
6. Stuck on 'galaxy note' boot screen, tried rebooting. Still stuck. (waited over 10 minutes)
Advice please!!
Did you try booting to recovery and flashing again? Or try clearing cache and delvik cache.

Yes, tried booting into recovery and wiping again, didn't work. Tried reflashing, still stuck. Tried flashing a different kernel, still stuck.
What's going on?!
Edit: I'm suspecting JBroid might be the issue here..have flashed in the past with no problem but this time decided to use JBroid (as advised in crash thread)..
When you say wiping, do you mean factory reset or wiping cache? If those didn't work flash a stable CM9 kernel, reboot in recovery, and then try to flash again.

Tried both. First just wiping cache/dalvik, then just doing factory reset (after installing notecore because of mmc_erase bug). Neither worked! The only kernels I have on my sd are notecore, abyss. Running out of options..may just try flasing rocket rom again..

Try flashing a pre rooted stock GB firmware and see if you get the phone to work. Then, try flashing from there.

Flashed back to RR v10 without any problems. Not sure why Crash wouldn't install but that was quite a scare!

Really digging the positive advice from everyone, thanks! It was a bad download. Downloaded again and flashed just fine =D.

[Q] Few questions about Roms, flashing and Kernels

Hi guys. I just decided to use custom Roms because stock is slow. I checked some Roms and 2 interested me: CM 11 and Zaiben.
1. Could you tell me about differences between them? At the moment I have got orginal Android 4.1.2 V20B. Is it possible to flash Zaiben from V20B, I am asking because in Zaiben's thread there isn't any information about flash from v20b. There is only about flash from v20a. And I can't post in that thread yet.
2. Also what should I do before flash new Rom. Will wipe data/factory reset and wipe cache partition be enough?
3. And could you tell me if I want to flash new Kernel I just use install zip option? And which Kernels do you recommend guys?
Thanks in advance.

1) Zaiben is a modified stock rom, cm is a completely independent rom based on open source project.
All you need to do is have the most updated recovery and you can simply flash right away.
2) If moving to zaiben you can probably dirty flash and don't need to wipe data since it's basically the same basis
If moving to cm you will most likely need a full wipe (system, data cache and dalvik
3) Yes - you canno't ask that question
Before you do any of the above you must unlock your bootloader to install cwm or twrp recovery!
Thank you for the help And last question: If I change Kernel what do I need to wipe after this?

Flashing kernel doesn't require wiping anything.
Each kernel has it's advantages and disadvantages. You need to read through their topics and find out which one will be more suitable for your needs.
Then I will try some. Thank you for help
