Flashing between roms without wipe the data and cache - LG Optimus 4X HD

Hi all,
I am currently using CM10.2. I am happy with it, but I might need MHL for somehow. Can I flash back and fore between CM10.2 to Stock without wipe my cache and data and I get
1, stable enough to run on both ROM
2, Personal data still good(still keeping like whatsapp history, contact data etc)
I am not brave enough to test by myself, hope anyone can help. Thanks
Mike

You can try it but you will for sure get a bootloop, especially with stock and custom rom. This way you are maybe able to change between custom ROMs with same android version, but stock is older than CM 10.2.

What you mean of bootloop is that you can't even make the device running without wipe?? Hey man, If I have the guts to try I will not ask. Haha..=)
Thanks anyways..

That's what I meant the differences between android version are to big and especially if you have a stock and a custom rom. Too many files/file paths are different and your system will screw up. It will boot, show the LG logo and reboot. That's why every single custom rom thread has the wipe part in it's instructions.
Like I said you can try it but I see no chance. I did it once between two custom ROMs (both CM 10.1) and even that didn't work out good.
It booted but every single app and system itself force closed repeatedly.

Help with Cyanogenmod 7.2 RC-1?

I've been having this problem with my p970 running CM 7.2. Ill be dicking around on NY dialer or even just dialing, and then it force closes and it says a message that "android.process.acore has stopped responding" this has happened in the last handful of nightlies, but not before that. I have tried reflashing, I have tried wiping everything (data,cache,dalvik) and I still get this error. I'm wondering what I'm doing wrong. Has anyone else got this message and or know of a fix?

did you restore your apps with titanium?and if you did did you restore data as well??some people solved this by not restoring data for their apps.especially apps that use the sync function.try restoring apps only without data.
I didn't use titanium at all. I just wiped everything and re-downloaded my apps.

Try formatting your SD card cache.not SD card data.only cache.in cwm go to mounts and storage to format it.did you try to fix permissions?if not fix permissions first and check if that helps.

try some kernels dude ...im using now cyanogenmod 7.2 rc-1 with nova 11c kernel no problems no far
SD cache didn't work at all... Where can I find kernels? Forgive me for sounding like an utter noob :/ I know you can flash them and I know them from linux. If I flash one (other than the default "kang" one" will it delete any of my stuff or make my device operate significantly different? Or will my phone act the same just (maybe) more stable?
also, are kernels specific to a certain build and android version?

Really light rom with decent battery life (ics or jb)

Hi guys and girls!
Hope you are all doing well. Anyway, I rooted yesterday and am running a new kernel (speed mod k13 I believe) anyway. What I am after now, is as the title says, a light, fast rom with decent battery life. I was wondering if anyone had suggestions or experiences and could suggest something. Would a CYANOGEN from work? When I had my galaxy s I was using 7 and found it really good. But are there others?
Cheers!

cyanogen will indeed work as will paranoid android charack,s,rocket rom if its lite you want then look for a rom with aroma installer so you can install what you want
Cheers!, really liking the look of paranoid android, especially the hybrid roms! it has been a goood while since i flashed a rom, so need to figure out what i have to do again. lol, thanks, if you can provide any tips on moving to this rom from stock ics with speedmod kernel, it would be helpful! Thanks.
Is this a decent guide to follow for paranoid android?

As long as you are on safe kernel you don't have to worry about anything or to revert back to GB. Just keep flashing rom with full wipes. Its enough for you.....
So, i am trying to back up through CWM on hydracore, it gets soooo close to the end and then says there was an error backing up the data, any ideas on what this is or a remedy for it?
I dont really want to flash a rom without doing the backup... even though in the past, i have done (old phone) is it imperritive to make a backup?

What exactly you want to backup from old rom, apps? If so then use titanium backup. I never backup whole rom as it hardly takes 15-20 minutes to setup rom if you have backup of apps.

Yes, as with any AOKP/ CM9 based rom..
There are alternative apps that could be used.
Otherwise, there are some excellent choices when it comes to Touchwiz-based roms as well.
Some are available themed to the AOKP look, if you prefer.

[Q] [i9001]From CM 10 to CM10.1

Hi All,
I'm currently on CyanogenMod 10 by ivendor - Beta 4 and I want to flash to CyanogenMod 10.1 Beta by Xistance.
Am I correct that I can flash CM10.1 without a data wipe, so only by wiping cache and dalvic cache?
I spent quite a lot of time by installing apps and setting preferences the way I want them to be so it would be great if all that could be conserved.
It works perfectly when going from one CM10 version to another, so I presume that this will also be the case when going from CM10 to CM10.1?
Thanks

Some ROMs (including stock) are a little laggy for our tab. In my opinion, C-O-M's cm10.1 and addem123's cm9 or PA do a better job with lag. None are perfect, but that's the best we can do on this tab, for now, and these ROMs are being developed actively, so they will continue to improve.
Also, overclocking any of these ROMs will help.

Cm 10.1 is jb. You should wipe cache and dalvik before you flash a ROM. Try flashin back to stock, then flash the cwm from com's thread, then make a backup, wipe, and flash the ROM and gapps.

[Q] Introduction and a question about nightly builds

Hello everyone, I have been lurking for a long time and I just want to say what a great community this is and thank you to everyone who develops and/or contributes. I have learned everything I know about android dev from reading these forums and I am confident enough now to start posting and trying to offer whatever I can from my experiences. Now for my question
What is the general opinion about flashing nightly builds? Is it generally only for people who are testing/debugging? I am running cm-11-20140805-NIGHTLY-moto_msm8960_jbbl on my Atrix HD right now and I am very happy with it - in fact I am ecstatic to have found a 4.4.4 rom that works smooth, fast, and stable for me (I got tired of waiting for AT&T to release their OTA update!). Consider this a positive endorsement of it. However, I see that new builds were released on 8/9 and 8/10 (as I would expect for nightly builds to be updated often, of course). I looked at the changelogs and I don't fully understand every last thing I see there, but I have not encountered any issues with the build I am running, so should I bother to flash the newest nightly releases when they come out? Is there a way to update without resetting everything or should I just restore my apps with Titanium Backup after flashing a new nightly? Finally, what is the best way for me to contribute to development (short of submitting code myself, as I do not feel confident enough to do so just yet)?
Since it seems I am not allowed to have a sig until I reach a certain number of posts(?) I will post my current devices below:
AT&T Motorola Atrix HD MB886
ClockworkMod Recovery v6.0.4.4
CyanogenMod 11 cm-11-20140805-NIGHTLY-moto_msm8960_jbbl (KK 4.4.4)

Nightly builds are just that, builds that are made nightly. They are the most up to date. Snapshots/M(*insert number here*) releases are generally more stable, but we got knocked out of being eligible for them after the release of M8 (thanks kk bootloader). CM has made a msm8960 jb bl section, which you did find. This might get us up and running for a M10 next month if they choose to do that, but then again, msm8960 did not get a M9. Nightly's are for everyone. CM makes a few tweaks to their code and pushes it to each nightly. Some tweaks make it better, some tweaks make it worse. If you are satisfied with the release that you currently are running, you don't need to flash the update if you don't want to. Since you would be flashing an update, you just flash it, no backups of apps. Now if you were going from CM11 down to CM10, 10.1, or 10.2, then yes, back them up b/c you'd wipe those partitions before flashing the ROM.

How would I go about updating without losing anything? Do I just boot into recovery, wipe only delvik cache, and flash cm-11-20140810-NIGHTLY-moto_msm8960_jbbl.zip? Or is there a separate file just for updating? If I don't have to set everything up all over again after each nightly then I will gladly keep updating and providing feedback.

You can just clear cache in recovery then flash the update and it would keep all of your settings, data, everything the same. It is not recommended. If you have enough space, you can nand backup your current version and that eliminates the risk of losing everything if updating doesn't work, but it's recommended that you wipe cache and wipe data before flashing a new nightly. I've rarely had a problem flashing a nightly on top of my existing build without wiping data, but to each his own.
Just make sure you're flashing the jbbl nightlies and you should be fine.

When you say "clear cache", do you mean "wipe cache partition," "format /cache," or "wipe delvik cache?" So basically what you are saying is that it is possible to flash a nightly on top of an existing build without losing anything but it is generally not recommended? I always create a backup image before I flash anything so no problem there.
Yes. Wipe cache. It will format automagically. You can wipe dalvik cache as well. Usually I just select the first "wipe cache" option in clockworkmod recovery then start flashing. Works 99% of the time.
Some say they develop problems doing it that way, but I've never had an issue with it. Maybe my phones (I had a moto bravo before the atrix hd) just like me.

The method of flashing over-top of an existing ROM is referred to as "dirty flashing". The issue isn't so much that it's not recommended or that it develops problems, but it could potentially develop problems, because there's always a chance that the new build relies on some random file that should have been deleted, changed, etc.
So, in summary, it's perfectly fine to dirty flash a CM nightly over your existing version, especially if it works fine for you. HOWEVER, if you develop problems, then you should refrain from reporting them until you have done a CLEAN wipe of everything and installed clean from scratch. If you still have an issue after a clean install, then feel free to report any issues as "bugs."

Depends on how confident you are
I usually just ask/report in the appropriate XDA thread and look for feedback. There is a thread for the Atrix HD, but the thread for the RazrHD is much more active. You'll get a lot more activity and responses in the RazrHD thread because it's essentially the same device, just be sure to note that you're on the JB bootloader.
I suppose if you're really sure of a "bug", you could always report it at cyanogenmod.org, but I've never felt to be in the right position to do that.

Well, then I just recommend sticking with XDA. If one of the real CM devs/maintainers then recognizes a bug, someone will report it. Or re-ask this question over there, and they can help you.

Did I do something wrong? I am creating a backup and "dirty" flashing the latest nightly right now. I was going to post how it went after I finished just so other people would have the info if they were looking for it.
Success! I rebooted into recovery and, after creating a backup, performed "wipe cache partition" and "wipe delvik cache" before installing cm-11-20140811-NIGHTLY-moto_msm8960_jbbl.zip on top of the build I was running. I rebooted and everything is as it was, except that my custom boot animation was reverted back to CM default (which was expected, no big deal) and the new version I flashed is correctly shown on the "About phone" screen. If I encounter any issues going forward, I will post in the appropriate thread.
