Stuck in boot loop every time I flash a rom

I've flashed a few roms now (masters stock rooted voodoo versions of nexus s firmware) and every time I do the boot logo just keeps on going until I do a battery pull and reboot, and then it's ok.
It's not a problem, I just wondered why this happens??

did you wipe dalvik, factory settings, cache?
did you change the kernel?

No. These roms don't wipe anything and I don't want to lose my stuff. I don't think you are meant to wipe with them either.

I was asking if YOU did wipe them because if you're going from one ROM to the other ROM you are supposed to wipe.
You lose your settings and apps. Back them up using Titanium Backup (Or any other related app).
Or.. better yet, just perform a nandroid backup. After that, wipe those 3 and reboot. See if the problem is resolved, if it is then you already know. If not then nandroid restore.

If you're going from one ROM to a completely different ROM made by someone else, you have to wipe data/factory settings!
If you're flashing an updated version of the current rom you're using, wipe cache/dalvik-cache.
If you're flashing different roms every other day, go buy Titanium Backup to backup your apps/settings.
And uh what ROM are u flashing where "you're not meant to wipe"

I am new to this so I'm still getting my head around it.
From stock I went to the rooted voodoo version of this - http://forum.xda-developers.com/showthread.php?t=971690.
From there I went to the stock rooted version of this - http://forum.xda-developers.com/showthread.php?t=979851
In both cases it says:
Rom Information:
Does it wipe: No
Does it flash the radio: Yes
So since they don't wipe, I assumed I shouldn't wipe anything, but it looks like I was wrong. From your post it looks like I should have wiped the cache and dalvik cache. I know how to do this in CW but I've never done it and my roms are working fine.
So next time master releases an update I gather I should wipe cache and dalvik cache yeah?
Also, when I do this will it remove any of my settings or apps?
Hope you can answer these questions, and thanks for advice so far.
<<edit>>
Just did a bit of googling and it looks like you don't lose settings when you wipe dalvik cache and cache, so what does actually get removed.

There is a thread stickied in development called ref roms themes and kernels. It gives step by step directions on how to flash all three including what should be wiped. Check it out

because its saying that the ROM doesn't wipe. Some ROMs are built in a way so that it automatically wipes your phone to ensure best performance. The creator is just saying that it doesn't do that BUT you need to wipe. The keyword does and need are two different things. The basic concept between going from 1 ROM to another (unless its the same ROM series) requires a wipe in all three: dalvik, cache, factory. If you're going from the same ROM to a newer version and encounter bugs, its best if you wipe.
I'm a more advanced user when it comes to Android since the first Android phone. I know what I'm talking about. When you go from stock ROM to another, its going to have bugs if you don't wipe.
If you're using Axura 1.1.1.0 and its fine, and he releases a new version. You can flash without wiping (but you can wipe cache & dalvik to be safe; none of your settings will be wiped). Wiping factory settings is the only one that will wipe your settings / apps.
If you're going to be a flasher, its best if you purchase Titanium Backup Pro (or MyBackup.. but I highly recommend Titanium Backup). Use this program and it will save all of your apps + settings to them. Just don't use it to save SYSTEM apps/files because it will cause FCs.
Dalvik Cache / Cache.. its nothing you need to know in particular. It's just removing cache that your phone set up to increase speeds. It just wipes them and gets the Android system to re-establish them. So no caches from the previous ROM will carry over onto the new one.

That is a very helpful post and clears a lot up. Many thanks. Looks like I had better do it again and do it right this time.
I've got titanium backup. Bought it after I rooted, but never restored with it yet. Also, thanks for the info about no saving system files with it, as I currently do have it setup to backup all user apps and system data, so I will have to change that. I gather I should just change it to all user apps??

Backup all user apps is the one you want to do. You can backup bookmarks using Google sync or a app known as BookmarkSB
If you have system apps backed up, delete all backups using batch and reapply user app backup

Thanks for your help. I reflashed the rom and I did it properly this time. Had a bit of a problem with TB restore as I'm a noob but Joel from TB answered an email I sent him very quickly and I got it sorted (thanks joel).
How long does it take to flash a rom once you get good at it? Took me a while tonight because of mistakes.

I can usually get from booting into recovery to having a usable device with most everything set up in about...10 minutes? Assuming I already downloaded the ROM lol sometimes those mirrors are slooooooow.

[Q] Help needed - Messaging FS after ICS

Hi,
I backed up my phone with Titanium and after updating to 4.0.3 tried to restore data only, from that moment - messaging force closing.
what can I do ?
thanks

Clear any messaging related data, reboot, and then see what happens.

Thanks but it's the same - the app loads and than crashes immediately,
Can I re-download the apk somewhere ?
I know it's core element - but maybe it can be extracted from the whole update ?

Well just to reiterate make sure you wipe all relevant system apps in titanium as that should do it (just want to be sure ).
But you could reflash the rom again, or part of the rom.
And yes you could pull the apps from the rom and install them without reflashing (though you will have to use titanium to make it a system app probably).
Oh yeah you could try wiping the dalvik cache.

tried wiping the dalvik cache did not help. how can I flash only the messaging app ?

Well I haven't done such a thing for a while but when I did a similar thing I did it like this:
1. Get full rom zip
2. Open zip with 7-Zip (or similar program).
3. Delete anything you don't want to be flashed again (I guess in your case nearly everything)
4. Flash
Note: I said open the zip, not extract it.
Can't guarantee this will work though I would personally just do a full wipe, flash the whole rom again, and be careful what you restore (i.e. don't restore system data).

Never use Ti to restore data after changing roms. It's the first rule of Flash Club.

[Q] Whtsapp stopped working and now throwing unknown errors

Hi everyone,
I have been using my nexus 5 since 4-5 days now and everything was working fine till last night when whatsapp started giving me errors (unfortunately app has been closed). I uninstalled whatsapp and when I am trying to re install it, its now giving me error "unknown error code on application install -24"
I have tried installing via apk, playstore's website, cleared the cache and data of playstore app, rebooted phone but nothing works.
I am hesitant to root my nexus 5 as there is no official recovery available and people are having issues when rooting the device and I cannot afford to have an unstable phone. Hard reset is an option but I would like to avoid it if possible. I have read that if I delete the related whatsapp folder from data/data folder somehow then it will fix the issue. Is there any way I could access and delete that folder without being rooted or if someone has any other solution to my problem.
Any help is much appreciated

Same thing happened to me, Did you enable ART? Because that's what caused my errors (force closing). After switching back to Dalvik and trying to re-install, i was getting -24 error on the play store. I rebooted a few times and left it for a few hours. Tried again and it worked.
Whatsapp is i believe in-compatible with ART.

Okay, As for as i know, it did fix itself when i rebooted a few times and after a while it just worked.
Things i also tried that might have helped. Clear cache for the playstore which you tried. i would do this again after you switched back to Dalvik. and make sure whatsapp is uninstalled before switching to Dalvik. Once you switch back and have cleared cache from the playstore, try to re-install Whatsapp.
As for the backup, on your phone is a whatsapp folder that has a backup of your messages and photos etc. When you re-install whatsapp it'll pick that up and restore your stuff. There is no need to delete that folder.
I Hope that fixes it for you.

Ok, Here is what I did.
After switching back to Dalvik I rebooted the phone couple of times, Cleared the data and cache of playstore app then tried downloading again but still the same error

Right so far thats what i did, and thats exactly what happened to me. I just left it for a few hours and tried again it worked. Just give it a few hours and re-try / reboot and re-try.

It didnt work. I had to factory reset my phone eventually and wasted my evening doing all the restores, I wish Android had a seamless backup system something like that of Apple's. Helium/Titanium/mybackup, all of them have some kind of flaws

I am not rooted at the moment so TB wasnt really an option. Helium works fine only for apps and their data but I am looking for something that can restore my phone exactly how it was before the reset including home screens, settings etc without being rooted.

That what you are looking for would be a nandroid backup made in a custom recovery, that restores everything. But not possible without root.

Hi,
I have the same problem. Error -24 if I want to install Whatsapp from Google Play Store. Local installation after downloading the APK from Whatsapp gives also an error (app not installed).
Tried several times to delete the cache and setting of the Play Store app and the Google Framework. Followed by restarts of the phone. Until now I was NOT succesful.
As far as I read on other forums, the problem is, that in data/data/ already exists a Whatsapp-directory and therefore Whatsapp doesn't want to install. You could delete this directory, but only if you are rooted. I avoided this step until now, because it's a new phone with warranty and after rooting, all data ist wiped.
I also tried adb to delete this directory, but same effect. Because the phone is not rooted, I can't remove this directory by remote shell.
Is there no way to clean up such remains WITHOUT root?
Greets,

Play Services force-closing - fix?

Yes, this is a straight-forward fail - I am running a CM13-based ROM and flashed a nightly build (has been redrawn meanwhile) onto my N5 without backing up first. Right after the first reboot, I received a "Play Services has stopped working" error message and this keeps appearing all the time. Additionally, the Google Now Launcher has disappeared from my launcher list - and of course, all the Play Services-dependent features don't work, i.e. Chrome, Contacts sync, Play Store and so on. So, my phone basically is useless.
I suspect all the problems arise from the non-working Play Services. I managed to uninstall them after deactivating the Android Device Manager and re-installed the latest version, but this didn't fix the problem. Is there anything else I can try? Or is there no way around a complete wipe?

have u flashed Gapps?

Tried it, but didn't help either. I'll just go for a full wipe now. But thank you for answering!

try clearing Cache and dalvik cache and then delete the host file from "etc" folder!

I should've tried deleting the host file. Wiping Dalvik and Cache didn't work before...
Anyway, I took the opportunity, put my 32GB mainboard in and set up everything from scratch.

Are you using amplify?

No, I didn't use that.

Uninstalled Updates to Android System Intelligence and Now Stuck in Infinite Boot?

Hi, I'm kinda at my wit's end with this problem that I'm currently facing and would very much appreciate some help. For some background, I'm on a Oneplus 7 Pro running stock firmware (OOS 11.0.7.1). I originally was planning on installing a Magisk module to spoof my device (Pixelify) to gain Pixel features. I noticed that one of the features was patching over the Android System Intelligence. It didn't work out the way I was expecting and I decided to uninstall the module. That went fine, but I wanted to make sure I was on the correct version of Android System Intelligence as well, so afterwards, I went into settings and "uninstalled all updates" to the app, which I assumed would have reset that particular app back to the version that originally shipped with the device.
Now, here's where the problem began. I restarted my device and I ended up sitting on the boot animation screen for over 20 mins. At that point, I knew something was wrong as it still hadn't booted into the system yet. I went into TWRP and decided to do a full reflash of the ROM (without wiping my data) and reflashed magisk as well. No luck either, still stuck at the infinite boot. So I went a step further and dirty flashed again without reinstalling magisk to see if it might have been any other modules not playing nice. Of course, that didn't work either and I'm still currently bootlooping. It's been going for the past 3 hours now...
In any case, would anyone have any suggestions on what I can do without doing a full wipe? I have access to TWRP and decrypting works fine. All of my files seem intact at the moment and from what I see, the ROM is has installed mostly fine, just something is causing it to hang during boot. Is there any way I can view the code running in the background during boot to see what's causing it to hang? Or maybe some other potential solution that I could try?

When you removed the magisk module and uninstalled the updates, did you boot into TWRP and wipe your cache and dalvik cache(but not factory reset or wipe data partition)? If you didn't wipe cache or dalvik, try booting into TWRP and wipe cache and dalvik cache(but DO NOT factory reset). To wipe cache and dalvik cache, boot into TWRP and sekect the Wipe option, then select "advanced wipes", you'll see a list of partitions, select only the cache and dalvik partitions(do not select any other partitions) then swipe the slider to initiate the wipe, when it finishes, reboot your device, it might take 10 or 20 minutes to boot because it has to rebuild the cache and dalvik cache with the new changes that you've made.
Generally, when making changes to the system partition, booting into recovery after making the changes and wiping cache is required in order for the device to load the system with the changes that were made instead of continiung to load cached data from before the changes were made, this tends to cause issues because the device is loading cached data that it can't use or understand anymore. Also, reflashing your ROM without wiping cache and dalvik cache would not solve this issue. You should do this any time you add/remove/modify/delete/uninstall/edit anything at all in the system partition, even if you only changed one tiny thing, you still need to boot into recovery then wipe cache and dalvik cache then reboot to apply the changes. This is not required when changing things in the user partition but it is absolutely vital that you do it when changing anything involved in the system partition.

Thanks for the response! Unfortunately, I already wiped the dalvik cache after I reflashed my ROM yesterday and it didn't end up being able to boot. Since the OnePlus 7 Pro is an a/b device, there's no other cache partition to wipe.
I ended up leaving it to run on the boot animation screen until it ran out of battery (just to see what would happen). Besides for the phone becoming burning hot to the touch, it just stayed at that screen for another hour or 2 before it finally ran out of battery. This leads me to believe that it's definitely doing something in the background at that time, but just not sure what.
Edit: Just for some extra context, I also created a flashable zip of the latest OEM version of the Android System Intelligence APK and flashed it to system/app through twrp. Since I'm not able to boot to unlock my device, I thought this was the only way to install the app. In any case, it didn't make a difference either. Not sure if this means maybe the APK wasn't the issue or if this just didn't install the app the way I was expecting. No error codes when flashing the zip though.

Use TWRP to create a backup of your device in its current state, then try to extract the data from the backup, if the data is intact, it can be restored once you get the device working. If your data is intact in the backup, you can do a full system and data wipe via TWRP then reflash your ROM then restore the data that you want restored. This "should" get you back to where you want to be. Be careful, be certain of what you do at every step or you may end up losing data or not being able to get it to work while at the same time be able to keep your previous data.

Just finished backing up my data through TWRP and and did a full reformat of my device. After reflashing my ROM, I was back up and running! So thanks for the tip! However, after restoring the data partition, I realized that the issue was with the data partition specifically rather than on the system side as I had the same problem again. So I cleared the data partition again but kept data/media (internal storage) intact, and just like that, the device booted just fine this time.
Would you have any suggestions on what I could do to to troubleshoot the data partition? I have some important app info that I need to get the data back from.
Or if not, do you know how to capture logs from a failed boot?

Logs from logcat do not persist through reboot. You need to look at your last_kmsg file, kmsg persists after reboot and it should capture the issue. If you have important app data, it should have been stored in data/media in your Android/(name of app) folder and your apps should be in data/data/app folder.
In the future, I recommend booting into TWRP and creating a backup before you make any kind of changes to your device, then, if the change causes an issue you can just boot into TWRP and restore the backup, this will put you back to what you had right before you made the change. Then you can troubleshoot what caused the issue and find a solution to how to apply your change without causing the issue again.

Yeah, lesson learned with that. I'm just glad I was able to backup my data in TWRP, which means I should theoretically be able to extract them back out again if I really need them. But back to the topic, I did check my last_kmsg file and it was unfortunately empty.
What I did do though was since I still have access to my recovery, I pushed my PC's adb keys to my device to be able to execute the command and grab a logcat during boot.
Could you by any chance take a look at the file (it's a onedrive preview link) to see if you might be able to notice the issue? I'm going into the territory of Googling everything and I was just completely lost when I looked at the file as I have no idea which errors actually matter and which ones don't. Thanks in advance!

Too many errors for me to volunteer my time to figure out.
All I can say is, at each line that reports an error, it states the error then lists the service(s) or app(s) that are involved in or effected by that error, everything listed after the error all the way down the list to the next error are related to that error.
Do a Google search for each error and the name of the package that immediately follows that error.

No worries, totally understandable. I think Titanium Backup might actually be my saving grace, as it's able to read TWRP files as well. So all I have to do is run my backup through that and have it directly restore my data. In any case, appreciate the advice you've given so far!

you might probably found a fix but you're supposed to put the other os in the internal storage and not the micro sd card since it wont detect bootable drives just like on a pc and if u didnt install the os on the sd card then you can search for a boot unlocker which can unlock your phone from the infinite boot based on your phone and os
have a good day
