about wiping when installing rom...

just a quick question, do you have to wipe your phone (alt+w) everytime theres a new rom update? for example if going from JF ADP 1.5 to JF ADP 1.6, do you need to wipe phone before applying the 1.6 update? or is it only necessary to wipe if your going from different roms for example JF to Haykuro..etc..etc
thanks

anyone have an answer to my question?

I'm curious as well. The impression is that you do not as long as you've wiped when you originally rooted.
I'm sure the safe answer is yes, you should wipe but that's a pain in the a**.

You should wipe IMO.
If you don't wipe and run into esoteric issues most likely you will be asked to do so anyways as it is the only useful troubleshooting tool most of these people have because
1.They don't know any better (no ones fault)
2.They don't have time take a look at your debug logs and then instruct you through some most likely intermediate-advanced commands to fix the issue.

Say you moved into an apartment and it's filled with the last occupants stuff. There's a blood stained sofa, stacks of magazine around the WHOLE apartment and a dirty toothbrush. Are you going to be comfortable sitting on that sofa? Would those magazines get annoying? Would you brush your teeth with the dirty toothbrush?
If you have to walk 10 miles, do you wear your own shoes or the last runner's leather shoes that are two sizes too small? If you can even get the shoes on you, you're gonna be in pain and give up within the first mile.
^_^
My answer is: Always wipe. Let the new OS use his own shoes.

ok i understand where you guys are coming from, but what if its only a small update to say JF ADP 1.6, and you are on JF ADP 1.5, it wouldn't make sense to do a wipe just for a small update. am i wrong here. now if ur going from JF to Haykuro then a wipe is definitely necessary. I read somewhere before, that mentioned you didn't have to wipe if you were staying within the same rom. i guess i just need a better understanding on this.

See the quote in my signature

hahaha! ok so I guess I will wipe before applying any new updates. what about the JFupdater app, it says it applys any updates, i dont believe the app wipes your phone before applying it, so is it best not to use the jfupdater when flashing an update?

My suggestion is generally this: Try it without a wipe. If it works, then great, you keep all your stuff the way you had it. If you run into issues that seem blaringly obvious(home process crashing, many force closes, boot looping, etc) then go back to the recovery image and do a wipe. There aren't any problems I know of caused by not wiping that can't be solved by going back and doing it after the fact.

thanks! thats exactly what i was thinking but wanted to be sure.

now wiping wouldn't mess up any links to the sd card(apps2sd) correct? wiping basically justs wipes the data from the phone....i guess what i mean is would I have to set up apps2sd again?

i'm with marcus, if you can get away with not wiping great, if not oh well wipe. or you could perform a nandroid bakup and then wipe, then after the update just fastboot flash your data.img

You would only need to restore the symlinks (if that's the method you were using).

[Q] Do I need to wipe data if I'm upgrading the same ROM?

I am relatively new to flashing ROMs & kernels for Android. Currently I'm using MIUI 1.5.6 and would like to upgrade to the newest version of 1.5.13.
My question is, do I have to wipe data if I'm just upgrading to the same ROM or would wiping cahce & Dalvik cache be sufficient?
Before anyone flaming me I have searched the forum prior to posting and surprisingly didn't find anything useful as I thought this would be a frequently asked question.
Thanks in advance!

I never clear if i'm gonna do the same rom and it seems to work perfect. So I'd say dont it takes less time but if your worried do it. clearing that stuff wont really loose anything so its your choice really

I think you ALWAYS should do a backup, just in case something goes wrong.
You have the device at the Computer, you have the cable hooked up.
What would it take... about 5 minutes to do the backup up ??

oddball69 is right. You should always do a wipe.
Just to avoid problems

Most of the Devs will specify for each version if a full wipe is not required. If you can't find anything about it then do a full wipe.
If they directly say a wipe is not required then it's probably just some small fixes.

Thanks for all the responses.
I was going to do a backup for sure I just wanted to avoid having to wipe everything and then reinstalling and re-setting up all my apps which could be quite a pain

Depends on the ROMs used, usually the developers state if this is necessary.
It wont hurt if you try without wiping, if it makes problem just wipe and do it again.
What is there to loose?

[Q] HELP flashing kernel PLEASE

I have just recently begun modding my G2x. I can install ROMs without any problems but I've since been interested in flashing a custom kernel. Information is sort of everywhere and what I do manage to find I am worried about it being out-of-date. Anyway, I flashed cm7.1 (the stable release) and it worked fine until it started fc-ing everything google related (something to do with sync?). I decided to try flashing kernels (wiping caches as instructed) and could never get one to work. I've since flashed the latest cm nightly (201 I think) and tried trinity with it. Still nothing. I've since read that I should let the phone sit for 10-20 minutes but after about 20 minutes it is just a black screen and nothing ever happens. It does get really hot however. Anyway I have tried flashing kernels multiple times and nothing has ever worked, same story every time. Any way somebody could tell me what I'm doing wrong? Tell me what's compatible (as maybe sorta stable) with the ROMs I'm using? HAHA and if it's not asking too much...maybe some links too? Sorry, just very new to this and very eager to learn. I just have a bit of trouble figuring out what's supposed to be compatible and where to find it. THANKS!

Start over fresh, wipe data x 2, wipe system x 2, wipe cache, wipe dalvik cache, flash cm7 nightly, dont reboot yet, wipe cache ONLY, wipe dalvik cache ONLY, flash kernel try faux123 (make sure kernel is for cm7) latest or morfic latest, reboot, enjoy ....
NVIDIA NEVER AGAIN!

Thanks will give it a shot in the morning. Too much of a headache all day. Back in a useable state and I want to keep it that way for a bit haha. Will post results.

I still haven't tried to flash a new kernel... that is coming in a bit. I do have a question though... I'm interested in getting my phone in the cleanest state possible before doing anything further. I basically want my external sd cleaned up (I want to just reformat it) before flashing a rom again. What files/directories are absolutely essential to keep? As I said, I want to just wipe it clean but I'm not sure I can do that.

So just to be thorough I can safely remove the cwm directory as well? Just delete it all put my rom and kernel zips back and I'm good?

Make sure you flashed recovery through nvflash
NVIDIA NEVER AGAIN!

Tried to just flash 0.4.7 and it did the same thing as before. Waited 20 minutes before taking out the battery then tried to boot it again. Waited 20 more minutes and all it ever did both times was get hot. Same results as before.

[Q] NS4G: How to start from scratch? And other questions...

Had a bit of trouble trying to do this last night, which resulted in a few hours lost sleep. I went formatting everything in CWM and realized after the fact, I also formatted the internal SD card. Luckily ADB worked in transferring the zip (learn something new every day).
Anyway, after all said and done, all my apps were still on the phone. This is after formatting and new ROM...
How can I truly start from scratch to make sure this new ROM is 100% fresh and free of any unnecessary apps from previous ROMs?
Also, what would be the best current radio and link to said radio?
TIA
EDIT: I had just realized the issue with Factory Reset/Wipe Data. This one I had forgot to mention as I could never use it as all options said no and the menu was not scrollable. Just decided to try and use the volume buttons and sure enough there was more to scoll to.
That said, would the following be a proper procedure to follow;
Wipe Data/Factory reset
Wipe Cache
Format: System, Data, Cache, Boot
Wipe: Dalvik then Fix Permissions
Install order: Rom first, Gapps second, Kernel last
Reboot
???

The method I follow is
1. Wipe Data/Factory Reset (this takes away all your downloaded apps?
2. Wipe system/cache/dalvik (this wipes everything else)
3. Flash ROM, Gapps, Kernel
The thing with android is, even if there are some files left over from the previous ROM, they'll get overwritten with the ones from my new ROM, taking them away regardless. The reason you wipe everything to make sure there aren't any files that won't get overwritten. So basically, wipe everything and flash, and you'll have a fresh new ROM also you don't need to fix permissions after you wipe everything because they'll be no permissions to fix! Lol

I don't know it offhand but its probably somewhere on the development forums. I just noticed I said "my new rom" in my original post, I meant "the new rom" just in case you were a little confused (probably not but that would've annoyed me if I didn't address it)

Newest radio I can find is from last year. Maybe that the newest. I know for certain signal and data is a million times better. However, I still have no 4g
And Im having an issue I ned to report about the ROM but XDA wont let me post... :crying:

the 10 min wait after rom install

I forgot to wait 10 minutes after a rom install! I got a bit excited Do I have to reinstall the rom or anything? Does this cause any long term issues?

Not sure what you are talking about.

It is likely that your version of TWRP is old or if you are installing android L preview it takes a while.

you don't have to wait for anything.. once its done, its done.

Is this like the wait parents make kids go through before they can open their Xmas presents?

Some KK stock based ROMs have rubbish updater-scripts that leave the ROM "formatting" for about 10 minutes. Not sure if this is what is being referred to as this is not technically after a ROM install.
That said, no idea what he is talking about otherwise

Hello guys! Thanks for responding super fast.
Im taking about the the "10min" wait that some developers say to have after first booting up a rom. Ive heard it was for all the little bugs and stuff to get worked out, so i should leave the phone alone. I forgot to wait this 10 minutes so i was wondering what would happen.

Yes, I remember the wait 10 minutes from my S2.
You don't see that recommended anymore. ?

WHAT HAVE YOU DONE?!?!?!??!?!
Just kidding, nah, you're fine. Like the post above me, the 10mins is more of a 'settling period'/recommendation than anything.
I remember rooting my Evo 4G and installing Cyanogenmod 7, not reading all the way through and neglecting to install Gapps: ".....where's my Gmail???? Uh oh, I think it's broken forever...." Ah, those early days of rooting and flashing, I remember them well

I think our modern processing speeds on these devices have eliminated the need for waiting. Just my guess. ?

The only 10 minute wait I have heard of is waiting for Dalvik Cache to rebuild before getting to homescreens. I have never seen a developer recommend waiting 10 minutes after booting... The first Android ROM I flashed was 1.5 Cupcake - so i'm not particularly new to this either :/

Every S2 t989 rom used to have the wait 10 minutes step after first boot. Lol I rarely did... Maybe 5.

I wonder if that was one of those "bad rumours" that started like wiping Battery stats... That fooled "developers" and developers alike.

like wiping dalvik when flashing a ROM, or better wiping dalvik to flash a kernel.

Hah yeah.
My favourite is "wipe data, wipe dalvik if coming from a new ROM".. Well duh, wiping data wipes dalvik anyway.
I never wipe dalvik myself, but many updater-scripts I end up using do

Depends on the updater-script. Some do, some dont.

Some kernel devs recommend to wait 5-10min after flashing their kernel for the first time (like Uber).
1. For best results a install these kernel after a fresh ROM install (although it still should work if you don't do that)
2. Reboot into recovery (needs to be N5 AOSP 4.4.4 compatible)
3. Flash Kernel Zip
4. Reboot and let Settle for ~10 minutes (optional but recommended)
5. Navigate to system/etc/uber_v1.3.cfg using your favorite root file browser and change values based on descriptions to whatever you want.
6. Enjoy!!!

When I had my Note 3, a lot of devs recommended that you flashed and let the ROM settle for 10mins or so before setting up. I never used to bother (still don't) It can settle once it's set up and goes into deep sleep.
