I'm kinda new at this but I switched my rom and kernal to lotherius 2.3.4 and was wondering if I need to switch my kernal back to stock or keep it... I want to switch to eaglesblood and don't wanna brick my phone once again (have one being used as a paper weight right now)

Every ROM should have a kernel cooked into it (99% of the time). Your phone will not boot if it lacks a kernel. When you flash a new ROM ensure you factory reset, wipe cache, and format system before flashing the new ROM. The only time you need to worry about flashing a kernel on a ROM is if you would like to change it, or in the rare case, if it lacks one.
Thanks so much :thumbup:

No worries man, I know what it's like to be unsure and its irritating. Just make sure to backup any apps you have, because wiping obviously will return the phone back to "stock" thus lacking apps and current system settings (alarm ect.)
Edit: I recommend titanium backup for backing up and restoring apps.
Cool one more question if u have the time. I went to install the new Tom and clockworkmod tells me it can't mount system I looked around on the fourms and could find a solid solution.?

Are you using ROM Manager? If so, that may be why... it has been buggy for a while it seems, but I always flash manually so I wouldn't know where it's at now. Boot into recovery by holding power and volume down (when the phone is off) and let go when the LG logo changes to another logo. From there do the three wipes (factory reset, cache, and format system) then flash ROM and reboot. (Format system is under mounts on the main screen)
K trying today ur a life saver

What would happen if I didn't wipe before flashing? And do I need to flash the 12.2 kernel
Sent from my SCH-I535 using xda app-developers app
I'm not sure what would happen. It would probably be less stable or not work... You could always try it though.
You do not need to flash any kernel. Only flash LeanKernel if you want to. If you don't want to mess with BusyBox, I'd wait on the kernel.

From my experience on other devices when flashing ROMs and not wiping I would almost always bootloop. Again that is my general experience. I would assume there would be similar results.
Sent from my SCH-I535 using xda premium
I usually backup the current ROM first, then factory reset before wiping cache. I end up with good results that way. The only time I installed a ROM without wiping, it was unstable.
Well, I tried flashing it, and it seemed to work. This is without the wipe.. But the only thing I found incorrect was that the wifi notification didn't go away. That was an easy fix though.
Should the battery life be noticeably better?
Sent from my SCH-I535 using xda app-developers app
Yeah I was kind of retarded the other day and forgot to wipe.:laugh: I was greeted with a nice bootloop until I pulled the battery and tried again (this time the correct way) then everything worked great..
I haven't wiped for any of the Synergy builds and my phone is running great Running Imos kernel too. Awesome battery life from this thing
So.. Even though I didn't get a boot loop after flashing without the wipe... Do you guys think I should just wipe and flash again?

A wipe may not be completely necessary but if you do run into problems (FCs, etc.) and post a problem the devs or users are going to ask if you did a full wipe or not - and then recommend that you do one. In the end it wouldn't hurt to wipe even if you are fully functional.
I used to hate wiping all the time but with the proper backup applications it doesn't take long at all. I use Titanium Backup to backup apps and then also do in app backups for specific things like nova launcher, minimalistic text, and gosms,
I flashed over the new HellyBean rom successfully after hours of work and hardship. It was a lot of trial and error till I finally fixed it. Now the only issue is an IMEI issue. I have checked out a few other guides....... long story short I'm lost and need help. Also something weird a few minutes ago when my phone was sitting locked doing nothing I got a bunch of texts and then I tried to make a call. Didn't work and all phone service is gone again. What should I do?
Are your apn settings okay?.... Is your imei restored to original now?

Flash Odin Gingerbread stock.
After that do the CWM and flash your ROM.
It happens to me when I repartition it will wipe everything.

Try to reset your apn settings and if that doesn't work then you might have to use odin to flash back to stock.
This happens every time I flash a JB ROM.
Everything else seems to work fine.
But...
As soon as I disable wifi, my mobile data greys out and I have no internet connection. If I re-enable wifi, my mobile data comes back.
If I am out of wifi range, mobile data greys out and no internet connection.
When mobile data works....it works.
Looking at my APN settings shows no APN's at all. It will let me populate a new APN, but when I press "save" it just goes away and leaves nothing. I've tried rebooting after also.
My IMEI information shows up in the settings screen. Not jibberish.
Flashing back to stock restores my mobile data fine.
Mobile data works fine when I upgrade to ICS from GB before attempting JB.
The phone reacts to flashing exactly as the instructions indicate.
This has happened every time I try to go from ICS to JB.
I tried completely wiping (int sd and all)my phone before flashing (over and over again) and I'm following andros instructions fully.
While on JB, could using Odin to restore an efs backup I made while on GB help this? Is it possible to just upload the backup without returning to stock? I tried to restore the efs backup with Root Explorer but it didn't fix anything obviously. And I can't seem to even connect fully using EFS Pro (won't see com ports on the Qualcomm screen). Nitrality is an app that claims to backup/restore the efs folder but I haven't tried restoring one yet.
I'm not even sure the problem lies within the efs folder.
Ive gone through this a million times and it is the same no matter what I do or "try". It is the same for me with any JB ROM.
Searching the forum has gotten me this far, but now I'm stuck. Any help would be greatly appreciated as I refuse to accept failure.

Re: [Q] Loose mobile data and APN's after any/every JB flash.
Now I'm thinking an app like GetRil might solve this. But the Infuse is unsupported.
Does anyone know of a similar app that supports the Infuse?

idk..this may sound silly but if you want to try:
1. go back to stock gb
2. take out sd card
3. factory reset
4. cm9 flash twice..run it to see it imei and data is intact. then boot into cwm. factory reset
5. flash a 4.1.1 build..check imei and mobile data.
6. then flash 4.2.1 build
...disclosure: i'm guessing
Re: [Q] Loose mobile data and APN's after any/every JB flash.
Hmm. Interesting. I didn't think of trying to step up the JB versions. I'll try that and report back. Thx.

I first re-downloaded all my ROM's and GAPPs on the computer.
I've been able to keep mobile data all the way to 4.1.2.(Paranoid) But after that it's as I described:
IMEI shows up and is correct.
No APN's listed and can't save a new APN.
"Mobile Data Status" shows disconnected.
If wifi is on and connected, mobile data "works" fine, but still shows no APN's and disconnected in settings as above.
Resetting to default APN says it completed, but nothing's there. I tried rebooting after and checking.
Wanna hear something really strange...
Since I knew I was going to have to go back to stock once again, I decided to step back to 4.1.2 just to see what would happen.
4.1.2 installed fine and my mobile data was once again working correctly.
Still working on it.

very odd...I guess your phone doesn't like 4.2.1.
Good luck with it, though.
Sounded like you've pin-pointed the problem to a change from the 4.1.2 to 4.2.1.
Im losing it all after i went back to stock gb 2.3.6
I changed the APN settings on my device as http://forum.xda-developers.com/showthread.php?t=1791526 advised. I'm running 4.2.1 AoCp and my mobile data, MMS, etc. all works fine.

Thanks but nope.
This happens every time even when starting fresh from stock.
I am not altering the ROM itself before flashing in any way.
Immediately after flashing a 4.2.+ from 4.1.2 the APN's are not appearing. But my IMEI info is.
But if I go back to 4.1, the APN's are there so I'm thinking the APN's aren't being deleted during the flash?
In the process of flashing, I've made sure all the ROM's "worked" and the APN's were there before stepping to the next one.
I feel like I'm insane.
Re: [Q] Loose mobile data and APN's after any/every JB flash.
Can anyone tell me what controls the migration of the APN info when flashing from 4.1 to 4.2?
Also, what controls the addition of new APN's and where are they saved?
Is there any place I can look within the ROM or kernel to help see if the APN info is really missing.
Personally, I think the APN info is there, but something is not installing completely when flashing.

I grabbed the UVKJ6 modem, flashed it, and APNs are displayed and working.
I've tested with 4.2.2 versions of Beanstalk, Paranoid, SlimRom, PAC, and The Collective's (shout out to dman who spoiled me with Zeus).
Tried to re-download and install the JB version of my trusty UCLB3 modem, but it would not work (for me) with any of these ROMs.
I've never been so happy to have my notification bar freeze! Lol.
I'm assuming this all has something to do with the stage of development for JB? Idk.

Good to hear.
You Prolly just needed to re flash a modem.

I had to flash a different modem. Not sure why, but it fixed my problem. What I did was:
1. Downloaded a few different modems from http://forum.xda-developers.com/showthread.php?p=31097259
2. Reboot into recovery.
3. Select to Install zip from SD card.
4. Locate one of the modem. (In the folder).
5. Flash the modem.
6. Clear cache and dalvik cache.
7. I selected to fix permissions. Probably don't have to do this. But I did.
8. Reboot and test. If it doesn't work, flash another modem and try again.
If no modem works, then its probably not the modem. Hopefully you removed the SD card when flashing from ICS to JB. And hopefully your IMEI # is showing and correct.
It goes quick. I hope this works for you. If you need more detailed instructions, just let me know.

Hey Guys - I am out of ideas and think my run with the charge might be coming to an end.
My phone is running FP8 stock ROM, rooted, with some apps frozen using TiBu. I have not issues with this set up since the update was pushed. I used tweak for a year or so, then went back to stock for FP8.
A few days ago my phone started to act weird. Widgets were not updating, apps randomly force closing. It was annoying but still usable. I decided to do a factory reset and then everything hit the fan. When I boot up the phone every app on my phone force closes and it is not usable. The "Setup Wizard" also force closes so I can not even get past that.
I have tried flashing other ROMs including Eclipse, tweaked, EP4 with pit, etc.The flash is successful but the force closes persist. I have also tried wiping data through stock recovery and CWM, but I do not think it works. I still see force close errors when the phone boots of apps that should have been wiped (twitter,TiBu, etc.). Anything else I can try? Pretty desperate as it looks like this thing might be toast.
Cliffs
Phone acting weird, reset data multiple times and everything force closes. Phone is not usable at all.
Tried wiping data but does not seem to work, downloaded apps still force close
Flashed different ROMS (both stock w/ pit and custom)
Still force closing. Help?
If the force closes are persisting even though data is wiped, you may have something nasty sticking around through dirty flashes (assuming you're flashing over the old). Make sure you clear all caches and if that doesn't work, it's a shot in the dark but you may want to try formatting the system partition through CWM and then reinstalling FP8 or whatever custom ROM you want. Whatever you do have backups ready...

Thanks for the idea. I am pretty sure I have already tried this but through CWM I will clear cache, davlik cache, data, and format system then try a flash of stock with .pit
Like you said, it seems like whatever is causing this is still sticking around even after all this clearing/flashing. Is there any way to clear these things through adb? Or would getting a log be worth my time?
If all else fails try odin.

I have tried flashing ROMS (stock and custom) through ODIN and to no avail. I am able to flash but it still does not overwrite the corrupted data. I still get force close errors for downloaded apps that should have been erased/over written. Even formatted my SD card just to be sure and didn't help.
Seems like my only option may be to somehow find and delete the data through ADB. Clearing through CVM and stock recovery is not doing anything. Problem is I do not know where this old/bad data is!

Never heard of PST when you posted that. Good idea, but I just tried a few flashes and the effect was no different than ODIN/CWM
This problem keeps getting weirder. So sometimes I am able to get through into the phone (even though I get force close pop ups every 2 seconds). I was able to uninstall most of the apps causing the FCs (not all because some are the system apps).
However, everytime the phone reboots the apps come back! Where in the hell are they being cached/stored to just magically re-appear after data wipes/flashes/un-installs. Seems like I have all these corrupted apps that I can not get rid of. Through terminal emulator I cleared data, and davlik but didn't help.

Yea, eventually I can get it to boot but the phone is not usable with all the force closing. The option to clear internal SD only seems to be available for the older ROMS, but I flashed ED1 and cleared it. No luck.

Yep I have turned them off. My settings also get reset however when I clear data, reboot, re flash etc.
Good question about the full EP4 ODIN. I have been using the ones from imnuts website, and have also tried the CWM packages from kvswim's thread in the development section. Tried Eclipse Beta 2 & EP4,EE4,ED1, FP8 stock. I also tried the CM10 ROM just to see if the change to ext file system would do anything. Not sure if any of them are labled as having rom,kernal and radios, but I would imagine at least a few of them are.
No matter what I do, I get outsmarted and all my corruped apps, settings and force closes remain.
I think you can skip activation after flashing ep4 and still get the ota's to get to fp1, fp5 and finally fp8. once there try activation, etc. Keep it purely stock no root. still fc's? IMHO your phone storage is hosed.

To skip activation - on the setup screen click on the Emergency Dial button. Once at the dialer, dial:
*#TESTMODE (or *#83786633)
That will "enable the soft keys", making it so you can then hit home to get to the launcher without activating.

Pretty cool! Didn't know I could do that. However once getting past that just about every app continues to force close including tw launcher.
Being that old apps & settings will continue to be restored after doing everything possible to get rid of them it must be a hardware issue.
Oh well, I will keep the phone around for the hell of it but guess it's time I look into something new.
