Full wipe, new Rom, old settings and apps

Hello guys.
I would really appreciate an answer to a question I have.
I installed leedroid 3.0.2 and I have the same apps and settings as before.
I think I haven't done a good wipe..
I rebooted to recovery from cwm and used the wipe before I installed the new Rom. (i was using the revolution 3.5 before)
After I installed the new Rom, when I booted on, all apps and settings were there.
Shouldn't the wipe thing clean everything and leave the phone "empty"?
Or, (most obvious) did I do something wrong and should do it again? Cause there is a little thing with the market that closes the process when I click on new released apps.
Thank you in advance guys.
Cheers !!!

Are you wiping data and cache in recovery?
"wipe data/factory reset"
It will then say:
Code:
-- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Data wipe complete.
Then:
"wipe cache partition"
It will say:
Code:
-- Wiping cache...
Formatting /cache...
Cache wipe complete
(second option is overkill)
Have you still got the setting to backup to Google servers ticked? Or any other app that you have backed things up with?
Whilst the last option wouldn't be instant (they would download again and take a good 5 minutes to appear).
And yes, you will probably experience issues if this is due to a missed wipe.

So, I will need to do a factory reset first, then do a cache wipe and then install the Rom?
(i don't remember doing all these for the revo Rom..)
Do I need to do these without rebooting the phone until everything is done?
Cheers !!!

Yes, you should always do the "wipe data/factory reset" before installing any new ROMs or if the dev has advised it, also between major update revisions.
You don't need to reboot. If using recovery to install the ROM just do the wipes then flash the ROM using menu.

Awesome. Thanks for the help.
Will try it now and I hope everything goes well. Hope I won't get stuck since am not in front of my pc.

Well, I did it again. Everything wiped out, started as new.
But still, new apps in market and battery history in spare parts give me a process termination...
Oh well, I guess that Lee will release an update.
Oh, something else I would like to ask. There is a new kernel for the Rom. Do I flash it the same way I flash everything? Through recovery?
Thanks again guys
Cheers !!!

I use Leedroid and don't have this problem. Today I have installed from scratch and gone back and forth between ROM's. i turned off all the processes that backup and restore apps and I get a blank fresh install.
I have to ask, the last time you installed Leedroid, did you use the downloaded one or a copy from your sdcard? is it possible you are restoring a copy rather than flashing a fresh copy?
And you don't have any apps that have backed up your apps such as Titanium? And you have turned off Google Backup and restore feature?
The thing is, it is handy not to lose data but we need to make sure your wipe is being done. Did you see the same messages in Recovery as I showed above?

gosh, it is sooooooooooooo weird...
i did it all again. factory reset, delete cache, installed the 3.0.3 version (which was released today).
everything seemed to go smooth. still, i went to market and clicking on the newly released apps list i get an error which is "com.android.vewnding" has been shut blah blah blah. and the same happens to spare parts. when i click battery history ""com.android.spare_parts" shuts down.
do you guys think it has to do with the kernel? should i flash lee's kernel (i couldn't find how to. i mean, shall i do it from the cwm recovery?)
i guess that the radio has nothing to do with all these, does it?...
thank you guys once again for your help
Cheers !!!

You have tried fix permissions in ROM Manager, yes?

eeeeeeeeeerm.... you got me. that is something i totally forgot to do :-(((
gosh.. i flashed the radio, sweet. tried to flash a kernel using jkoljo's tool and it stayed on the white screen (and of course cold sweat was all over the place )
but i flashed the rom again after clearing cache and the likes and (thank god) i'm in.
but the most weird thing is that, after all these, the kernel is flashed :-S
i checked in the phone info and the kernel is there..
anyway, am gonna do the fix permissions thingy and reflash once more. if it stays the same way, i'll have to live with it. it's late here in greece.
thanks again for your help guys, i really appreciate it )))
Cheers !!!

i did it all again but nothing happened.
did the permissions, rebooted to recovery, factory reset, cache wipe, install new rom and nothing.
i have to tell you guys though.. the problem with the market started when i was on the revolution rom. and it started just like that. one day everything was fine, next, bam. it didn't budge.
do you think there might be something wrong with the phone itself? (probably not and i'm paranoid)
other than that, everything works nice.
oh, and some other thing. there is this "full wipe 1.3" zip i had put in my SD card but never really used it.
should i use it this time?
this app should clean everything in the cache but not my files, right?
Cheers !!!

YouTube clip of how to manually full wipe everything.

When using this method I've never had a problem.
Sent from my HTC Desire HD using XDA App

I did the wipe as shown in the video. The problem remains the same. New market apps list gives an error followed by a restart of it and spare parts battery history does the same (without the restart though)
I don't know, I'm thinking of trying a different Rom even though I like the one Lee released.
(could all this mean that I have a problem with the phone?.......)
Anyway, thank you guys for spending time helping me.
Cheers !!!

[Help] Every thing wiped, now what?

So here's my story:
I was kinda sick of the stock ROM, so I wanted to try out the Open Kang Projekt's ICS. And in order to do that I need to install Clockworkmod on my devise, and I did. But instead of installing the official CWM (which is version 4.0.0.4), I tried this: [Recovery] ClockworkMod - 5.5.0.4 - (Update: 03/18/12), I think it has the latest ICS kernel included or something (I'm not sure, that's what he said). And then I installed Kang's ICS ROM. Everything worked out just fine, except for the fact that it takes me every time about 5 minutes to boot, which is really a pain 'cause my tab crashes alot, and there are other bugs as well. So I decided to have a stable ROM instead of an unofficial ICS. But now I can't install any other ROM. I tried CLEAN ROM, team Overcome's ROM etc. but there's no luck, I'm always stuck at boot (Yes, I did wiped anything I could in CWM).
So now, what can I do?
I have wiped everything and flashed the official CWM 4.0.0.4 with Odin onto my tab, and I think that's the only thing I have on my tab now.
If I want to install Overcome's ROM now, what do I need. Do I need to install a bootloader? A kernel? What kind/version do I need. Shall I install the kernel first and then the ROM or the other way round?
And if I want to go back to stock, what do I have to do? Can I do that with Kies?
Really need some advice here. Hope you guys can help me.
BTW, my devise is Galaxy Tab 10.1 Wifi only.

Whenever I change my ROM, I always follow the steps outlined in S0ckM0nk3y's guide (stickied in the development section).
1. Use Odin to flash stock ROM
2. Boot into stock recovery and do a factory reset (I do it 3 times cuz I'm anal), also wipe the cache too
3. Now you should be back to stock ROM.
Make sure to thank S0ckM0nk3y for his very helpful post!!

Do you mean the root and unroot thread? I don't really think that's what I need but I'll try to flash the stock from via Odin as you said. Thank you for your advises.

Yes, the root/unroot thread. Doing what I posted will get you to stock ROM. From there, you can try to load another ROM. I personally recommend task14 ROM. Make sure you read all instructions thoroughly as many times as necessary so that you fully understand the steps before you go on and flash anything. Task's page is pretty straightforward.

Thank you. Everything's fine now. After installing the stock rom via odin I still got stuck at boot, but then I flashed the stock recovery (the 3e one) and did a factory reset with it, everything is back to normal now. I'm on stock rom again. Thank you very much for your replies.

That's quite the process. Not sure what went wrong for you in the first place (sounds like you've never done this before, from the wording of your questions), but all I do when I flash a new ROM is wipe (dalvik, then full wipe) and then flash. Never had to use ODIN except to flash CWM (and I've only done that twice, once when I got the tab and again a few weeks ago when the CM9 team released their variant).

That's what I meant when I said "I wiped everything I could". I did wipe dalvik cache, full wipe with CWM recovery 5.5.0.4 but somehow that did not work.
But now everything's fine again, after I wipe data/factory reset with the stock recovery instead of CWM.
I'm not sure of what went wrong either, but since everything is back to normal now, I think I'll leave it this way, no more custom rom.

I was actually referring to Swammy's process. No big deal. I can't imagine using a stock ROM at this point (especially since I've been using ICS for over a month now), but to each his own.

The only reason I go through that whole ordeal is because I hate all the cluttered folders on my sd, and cwm won't clean up any of that after a wipe. I admit, my method is a bit anal...but I do always go to stock, then wipe, then install cwm and load a fresh ROM. Is there a better method that I a unaware of? I am open to suggestions!

I just use storage analyser from the market and occasionally clean house manually. Takes 2-3 minutes, and forces me to stay aware of how the storage is used (I do the same thing on my windows computer, though it takes much longer!). I probably have some useless directories but, honestly, there's no advantage to having the vanilla folder structure. But, if that's your purpose, I don't know another way. I just pointed that out because noobs will read this thread and since your post is the first response, I'm just playing damage control...

[Help Needed] Apps won't restore or install after flashing rom [SOLVED!]

Well, my first venture into rom flashing hasn't been the most successful one as it's caused a really strange issue that a couple people on another thread have tried to help me solve, but I figure I had hijacked that thread long enough so this issue deserved it's own thread.
I rooted, unlocked bootloader, and installed TWRP v2.4.0.0 on Stock Android 4.1.1. Everything worked great. Until I flashed a rom. Now, I have been through wiping Cache, Dalvik Cache, Factory Reset, Flashing the rom (I've tried 4 with the same exact issue), flashing Gapps... All seems to go well and it says "success" when I flash, and I reboot into system. Run the setup of Google. Everything seems great and working fine. Here's where the problem is. When Google Play Store starts downloading for restore, and I'm on a solid wifi connection, nothing downloads. I have also tried stopping the downloads and installing apps individually. When I do that, I receive the same error message over and over for any app:
Unknown error code during application install: "-24"
I've rebooted, wiped cache, dalvik cache. Nothing installs. Same error. I did somehow, some way, get Titanium backup to install after numerous tries... when I try to restore any of that backup it just hangs on the first app. It does not restore anything. No batch apps. No single apps. No app data.
The odd thing is, the first time I flashed a rom, it seemed to load up fine. Stupidly, when I was running Titanium Backup for a restore I was not paying attention to what I was restoring. I was restoring all apps and app data... It caused an issue and a bunch of force closes, as you can probably imagine. So I rebooted into recovery and wiped and reinstalled rom and gapps. And virtually nothing has installed since. I have wiped and reinstalled AOKP, PACman, Carbon, and CM to no avail. Nothing seems to solve my issue. I'd love to at the very least be able to regularly install apps from the Play Store. At this point I'm not even concerned with restoring app data if that's too much to ask. I just want to be able to use my phone normally again as this is my "daily driver". If I have to go back to 4.1.1, that would be fine with me. I just want to get back to normal. And I'll do whatever it takes to get there. Any help at all would be appreciated.
Here is the original thread that some people have been giving me great advice on as to what to do, but none of it has fixed the issue yet unfortunately:

2 suggestions:
1) i think others have reported having issues with TWRP 2.4, so try 2.5 or 2.3.2.3
2) I think the error could be a lack of internal storage, so certainly try the "wipe internal storage" in TWRP (after making sure that your ROM/GApp files, backups (including Tibu) are saved to your external folder

Ok giving this a shot. I did notice that you had mentioned a different version of TWRP than I had. I will try the wiping internal storage before I install a different TWRP then if that doesn't work, TWRP. Gotta find the external folder. Unless you just mean anything that is on the actual SD card.

i would actually recommend installing TWRP 2.5 first.
never wipe external SD card.
if you have an app called Root Explorer, that works best.

Ok I'll try 2.5 then. And I wasn't gonna wipe the card, just was wondering if when you said external folder you were talking about the SD card. Root explorer works great.. if i could install it.
EDIT: Since I am away from my computer, I tried the multiple wipe method. Didn't change anything. So I will be changing TWRP versions later and will post an update.

You never mentioned using TWRP 2.4. DEFINITELY replace that. Also, just a thought. If you haven't already done so, try using the option to fix permissions. I'm fairly sure its an option in TWRP.

Back in business! Wow thank you all so much! What a pain it's been but without the help I'd have never guessed how to get this running as perfectly as it is now. Here's what worked for me:
Installed TWRP 2.5 (Instead of what I had, 2.4)
Then followed jco23's precise directions:
jco23 said:
- I use TWRP 2.3.2.3 (SS has been uninstalled via it's own app, not Tibu or the system awhile ago) - but TWRP 2.5 works just fine for others
- after downloading the ROM and GApps (or any file that I intended to flash for that matter), I always place the file on the mnt/external1 directory. I
m not sure if this will make a difference, but I recall it being an issue back on my Droid Charge days
- after flashing the files, does TWRP say successful?
- perhaps you do need to a double wipe of everything prior to flashing:
1) mount everything
2) wipe cache
3) wipe dalvik cache
4) wipe system
5) factory reset/wipe data
6) wipe internal storage (if you do this, make sure to change your TiBu backup folder to your external1 directory, or this will be gone too!!!!! also make sure that the system backup you made is on the external1 directory as well
7) reboot recovery
8) install ROM
9) install GApps

And it's working flawlessly. Able to download or restore anything from Gapps. Was able to restore some specific app data from Titanium Backup (did not want to ruin the phone again and do that full restore so I selected specific apps that I really wanted the data on).

Help with wipe-rom-kernal for first time, If have donate button I can donate cpl$

Im not rich or I would have got a newer version tablet by now, but if anyone who helps has a donate button I have no issue donating a couple dollars to the person who helps me get this done, Thanks. Or just a couple dollar PP gift. better than nothing I guess.
I just want to be sure I dont mess anything up here. I have a nexus 7 wifi model.
I used NRT to unlock and root and all seems fine. Am I correct in this:
I use nandroid backup to backup first
Put ROM file on device (where do I put it?)
Wipe (is this done via nexus root toolkit or is ok do do in the custom recovery?)
Then what, boot into recovery and find the ROM and install it via recovery install button?
Then do I do the same with a kernal? Where do I put it?
Then done?
I know there are guides around but for a complete newbie I need to be sure cause I dont always see a complete fully explained step by step. Just like when I was stock not getting SU to work after rooting via nrt, I did read to flash SuperSU.zip, but had no idea how, then when I found the file and thought maybe install from recovery meant same as flash, I didnt know the message about messing the device up was normal so I was afraid at first.
THANKS to any replies,
Been unsure for days now trying to make sure my ducks are in a row before i commit to a ROM/Kernal. I want to CPU control for both under and overclocking etc. Mainly overclock just a little. I must say I love root already, got stuff to work I couldn't before

1. Create nandroid- there's a free app called something like nandroid on line - very simple to use
1a. I'd also recommend backing up with titanium backup app. It means you can keep your app data (e.g. game progress) when switching between ROMs, unlike a nandroid which is just a backup of your device as a restorable image
2. Put ROM file on device - ROM will be a .zip file, out it wherever you want, as long as you remember where it is
3. Put kernel anywhere on device - easiest to find a kernel with .zip format (recommend M-kernel)
4. Wipe - from custom recovery
5. Hit install in your custom recovery, I always flash kernel and then ROM, but I don't think it really matters
Install from recovery and flash are the same thing.
I'd recommend only flashing ROM or kernel and sticking with that set up for a few days, then flashing the other desired element. That way, if anything goes wrong then it's easier to pinpoint.
Good luck!!

Actually that completely matters. Flashing a kernel before rom is worthless because the rom contains a kernel that will replace whatever you have just flashed.
If you want to run a custom kernel on a rom it is recommended to boot into the rom first before flashing the kernel.

If I just want root access and overclock should i just flash kernal and forget a rom?
can i revert back to stock kernal if need to? ask cause need to find a kernal that has V4L enabled for a usb camera app i use currently to use an inspection camera via usb on my tablet. I guess i need to read what various roms and kernals add. do i need to do both. Hard to know what to pick out of them, lol.
Thanks for advice.

Anyone know of a list to show ROMs with V4L enabled? None seem to mention it?

I have read and see different suggestions around on various sites. What all do I wipe? I have read cache, dalvik cache, plus other stuff. What all must I wipe before flashing a rom or kernel? I did a nandroid backup already.
PirateGhost, Ill donate a couple dollars if you help, thanks.
Thanks.

When going from one rom to a different one all you need to do in custom recovery is select factory reset.
This wipes out your currently installed apps, their settings, but doesn't touch your 'sdcard'
Wiping dalvik is pointless as it's automatically handled in the rom process, and cache is wiped in factory reset.
When switching kernels follow the instructions provided by the dev. If no instructions are provided, it's safe to assume you just flash without wiping anything.

When doing this, I'd recommend titanium backup too. When you do a factory reset, all apps are lost, but some data is kept (not sure on the details). Basically Titanium allows you to restore all your apps with data when you change ROMs.

When going from one rom to a different one all you need to do in custom recovery is select factory reset.
This wipes out your currently installed apps, their settings, but doesn't touch your 'sdcard'
Wiping dalvik is pointless as it's automatically handled in the rom process, and cache is wiped in factory reset.
When switching kernels follow the instructions provided by the dev. If no instructions are provided, it's safe to assume you just flash without wiping anything.

Thanks! Ill donate a couple dollars later today when I get back from the doctor.
I have not put any customs ROM(s) on yet, so is it the same still? All I have done so far is unlock/root with custom recovery and nandroid backup....

Yeah I backed up the one app I needed to via TB, I just recently unlocked and rooted so lost most app data anyway and have only added one back so far. Thanks.

No data is kept except what's on the sdcard. Mostly only game saves and some basic stuff. Apps databases are wiped during factory reset.

Nexus 6p weird bootlooping.

Hello xda community!
I received the nexus 6p christmas and after a few hours playing with it, I unlocked, installed twrp and installed cm13. I then installed ak kernal. My phone installs both fine and runs as normal without any FC. Then this is where it gets weird. When I had my new rom and kernal all set up. I go into TWRP and create a backup. I restart and I'm bootlooping. It tells me my device is corrupt. It did this with the original backup of stock rom, cm13, with and without ak kernal installed... and then sometimes my phone will soft-brick (gets stuxk on google logo) I really love cm engine as I habe a theme. But I'm unsure what is happening to my phone.
Any help is appreciated! - thanks.

Wipe everything > Advance Wipe Phone in recovery
Reinstall CM13 through Recovery and don't flash another kernel
:good:

Whoa! Don't tell him to wipe everything in the advanced wipe menu, that'll wipe the internal storage too which is completely unnecessary.

Which partitions are you backing up when creating the nandroid with TWRP?

System, data, boot - Installing the kernel made no difference, the device still corrupted on reboot. and then sometimes at least twice it has soft-bricked

The bootloader message won't go away until you lock the bootloader. Its just there as a warning to you in case you did not unlock your phone. As for CM I'm sure there are still many bugs to be worked out. I know I'm going to wait before Flashing it until I see people enjoying it as a daily driver. There are some great devs here in the n6p forums though so I recommend checking out some other ROMs too.

Maybe this will be helpful. I think you have the red level warning like this user. Seems like the exact same situation.
http://forum.xda-developers.com/showthread.php?p=64403982

Turns out it isn't bootlooping. Its taking at least 3 minutes to turn on. It looks like bootlooping. BUt if finally loaded. After doing my uninstalling of aomw system apps. Its rebooted and keeps optimising apps. 2-4 then restarts and does same

It s necessary to Wipe everything when don't know which modification cause the problem.
+ Recovering the backup also not working for this situation.
@Xtra-arrow

more detail = better help

No it isn't necessary to wipe the userdata partition. No modifications are stored in the userdata partition. It would only be necessary to wipe system, data, cache, and dalvik cache. And probably flash the vendor partition too. Not userdata though.

I had a similar problem when I botched a SU flash, same warning then it would take forever to boot, then the rom would degrade over the next several minutes. I know its not fun to start over, but it was the only thing that cleared all the problems. I didn't want to take more time finding another solution when going back to stock is so simple with this device. Follow the instructions in step #11 of Heisenberg's guide (great guide, I link it to friends a lot). Then start again, I know, not what you wanted to hear. Hope this helps!
I am also in agreement with Heisenberg in regards to the userdata partition.

Thank you very much for replying. I have found the root of the cause but no solution. Uninstalling or disabling system apps will cause my phone to go into a "optimising apps" boot loop on the next restart. What do you think? ++ every restore I make on twrp either soft bricks or bootloops. Crazy!

If you are sure about reason Forget ur Backups.
you should completely install Stock Kernel, Rom, Boot.img >> Back to Stock
But If I remember correctly u did this before...
I just have to say Retry Also Install and use Nexus Root Toolkit
:good:

I have reinstalled original stock files from google. I've wiped everything numerous times. Installed ROMs just after. It took me a while but I think it comes down to the system apps. I'm running a custom ROM, cm13 and my phone is running fine. I know if I was to delete all the unwanted apps off my phone, on next reboot it will try and optimise apps, finish. Says starting apps... Then reboots. Follows the same process.

Can I ask what gapps are you using? Are you using your google account to recover your apps, or are starting fresh each time?
Sent from my Nexus 6P using Tapatalk

Thanks for your reply. I've actually now narrowed itnright down to a few apps, maybe gapps. Sound recorder, voice recorder app and the google app. Either one or more of these cause my optimising apps bootloop.
