fix/bypass signatures do not match the previously installed version - General Questions and Answers

So i need to back up app which has backup function disabled, so i decompiled app, changed backup to true and compiled, app installed and i could back it up with adb but data was gone, i needed to keep /data/data/com.myapp so i did, with pm uninstall -k and it kept data but now i can't install my modified version, it gives me error "signatures do not match the previously installed version" is there any way around this?
i don't need some root solutions, my goal is to back it up from pc with adb without root
i also tried to extract data with app not installed, but didn't work, what tells phone not to back it up if app is not installed? data itself?
EDIT: oh boi, i just realised this is general thread, can't delete or move, mods please? xD

can't recall solving it. my guess is that it's not possible on newer android versions anymore

The app data will be encrypted, only way I know of is root and use titanium backup pro or similar app

Issue with Titanium Backup?

So i just updated to the new version of Titanium Backup on my captivate...it keeps crashing on startup...yes my phone is rooted, i have the latest ver of busybox installed. I uninstalled it and reinstalled it, it asked to get the latest ver of busybox which i already had and then it keeps crashing...any ideas or has anyone had this prob so far?
Im also having this issue.Its nothing you did wrong. If you check the comments for the app, many users are reporting this problem, fir different phones.

Update posted overnight appears to fix it.
Titanium backup is telling me to go to setting and then into applications, and then to check a box dealing with unknown sources.....but i don't any such box, anyone else see this?

You don't have that option on the captivate. Ignore it. Make sure you got the latest version of TB. Launch the application. Click on problems. Let it install busybox (yea yea you have it)... and it should be ok.
thanks for that...along the same lines, i am trying to re-install my media hub apk, using appsinstaller, say the phone is blocked from non market apps....i am using SRE 1.2.1a
I'm not sure about that.. but..
http://forum.xda-developers.com/attachment.php?attachmentid=388191&d=1282780888
there's a link to the apk again. Try to sideload it.. or first try to make sure you actually have market access .. here's an app to test it: Furdiburb
look for it in the marketplace and if you are able to download/install it then something's up @[email protected] and I'm not quite sure as I've never used appinstaller.
For the captivate you have to edit settings.db to enable non-market apk files to install. There is a guide on these forums and on wiki sites. It's not that difficult.
Reply back if you want more information.
Titainum backup will not restore properly unless that settings.db is edited.

"App not installed"

Hi guys, I'm desperatly seeking help here.
I just rooted my n5 and I decided to install a custom rom (Resurrection Remix). I managed to have it run perfectly on the device but here's the problem, when I tried to restore apps and data from titanium some applications didn't install showing "App not installed" (the actual message is in italian but I think you get what I mean). I have unknown sources active so I thought it must be a kind of bug of the rom and I tried installing CM12.1. Obviously I'm not that lucky and I got the exact same issue with the exact same apps (eg Monument Valley PAYED from the Amazon App Shop and another couple of apps that worked fine before).
I tried wiping cache and dalvik via twrp but nothing. Even if I try to restore the app from the amazon shop (or reinstalling the apk of the other ones) it still won't work.
Flashing factory image of course fixes it but I want a custom rom and I don't think I can have it at this point.
HELP
I'm not sure what is causing the issue, but a workaround you can try is to convert all your app+data files into a flashable zip (its an option in titanium backup) and try to forcefully install them by flashing that zip in recovery.

You can also get rid of TB and use mybackup pro, my opinion, works much better

I've used TiBu for years and it has never failed me. In what way do you think mybackup is better?
I just checked the features list and honestly there is barely any difference. It offers a few small things like setting multiple backup locations, and other small rather trivial (imo) things, whereas titanium backup offers major features like restoring data through zips. Each to their own, however.
I FIXED IT
Since I've seen this is a common problem I'm gonna share the solution.
So, let's start off by saying the problem is a bug in the choice of the installation directory, you have to change it to "internal" and not to "auto" which is impossible via app settings so you'll need the adb shell.
I'm not going to say how to get all that stuff done but it's pretty easy.
Once you have root access on the phone you should connect it via usb, open a cmd prompt and type:
adb devices
adb shell
su
su -shell
pm set-install-location 1

Click to collapse
If you want to check simply type
pm get-install-location
Click to expand...
Click to collapse
and you shall see

That's it. Fairly simple all in all but it took me a looot of time to get it to work.

Recovery Software for root content - /data/data after factory reset?

Hey guys, I've got a problem. I want to restore my com.whatsapp dir in /data/data/, is that possible somehow? Someone had a similar problem back in 2015 and it is said that he could not restore any, but I have software which backed up all videos and photos, but it didn't recover the files I wanted (because you only could choose things like: doc's, pics, movies etc).
Do you guys have an idea, please?
Or do you guys know how to verify whatsapp? I've been using my old number for 5 years now, 2-3 years ago I got a new sim card. Since then, I've always made a backup with titanium or took the backup from whatsapp itself and if you enter ur number and whatsapp recognized a backup, it didn't have to verify anymore. But it's been changed now somehow, they want to verify one's number and then it'll first try backing up (but I do not have that sim anymore). And unfortunately, titanium backup made a corrupt file exactly with the whatsapp file <_<
Thanks in Advance!
WhatsApp doesn't store your media (received images, videos, chat messages, etc.) in the com.whatsapp folder in /data/data, but it stores it in your internal sdcard itself in a folder named WhatsApp. Take that folder with you and put it in the new phone/tablet where you want to continue your WhatsApp usage.
Verification is straight-forward. All you have to do is do a fresh install of WhatsApp on this new phone/tab of yours and start it. If you had placed this backed-up WhatsApp folder on the internal sdcard of the new device, WhatsApp will ask you and automatically import this media on your new device.
Hope that helps.
Hello, thank you for your help.
As I said, I don't want the media, I want the data of whatsapp. I backed up all the media anyway and the recover programs only recovered the media, but I want to recover the whatsapp data.
"WhatsApp will ask you and automatically import this media on your new device."
That is how it used to be, I think they changed their system. You now first have to verify your number and afterwards, you're importing ur whatsapp backup folder. after verifying to another number (not the one I wanted) my old data has been backuped.

In that case, I don't think its going to be easy to retrieve the old chat contents easily unless you have WhatsApp running on your older device. If you have it running on the older device by any chance, you can refer to this manual and create a Chat Backup to your Google Drive, so that later you can restore it from Google Drive on your new phone/tablet. I suppose this is the only way to create WhatsApp chat backups going forward.
Well, I flashed another rom, so I don't got any possibility to return to that version. That's why I ask for an recovery software which also can recover root files. I didn't think it would be so hard to find, because there are some which recovery plenty of other files, I just needed one which includes /data/data folder AND any files, no matter which ending they have (like *.*, where * is a wildcard for any matches), so I hoped someone of you would know any software?

What software did you originally use to take the backup? If it was Titanuium Backup, then what went wrong while restoration?
In case you have the actual file system backup of /data/data/com.whatsapp, you can directly try pasting that folder in the new setup using Root Explorer (or similar app) and see whether it works. But of course, you'll need to be rooted on your new setup.

[ROOT NEEDED]
Maybe GT recovery is the app you are looking for. Basically this app recovers your lost data even after a hard reset by exploiting some resources in the root directory. By this app you can recover the whole folder of your WhatsApp. Just type in the full directory path in the app.
May this help you.
Unfortunately, the exactly the whatsapp backup is a corrupted .rar file, only has 0.0 kb data... @tiger1487 I got root on my phone, but the problem with GT recovery is, that you need the paid version for using it. But tbh, I'm not willing to pay 15e to try if it eventually could recover my needed data, so I'd ask you, if you know another software which is similar to this one? I can't search for one unfortunately, because if you google for it, you just get some to backup a factory image via cwm or twrp or something :x

I am a new member so i cant send you the link of the all free GT recovery but i can tell you that just type 'GT recovery cracked' in the google search engine. You will get it for free[Tip: If you type 'cracked' in front of any app name on google search, you will get it for free, just look for some trusted website like 'onhax' or 'okhax' or 'crackedapkfull']

And I forgot to tell that GT recovery is now more updated. Now there is no need to type in the exact path. There is a direct option for Recover WhatsApp. Likewise there are other options too for messenger, call logs, etc if you need it?

Oh, you were talking of the app, thought of the windows software. The app itself is free, isn't it? I tried the app, it stucks at 0% scanning and I don't think it'll work. Tried different apps, it seems they're only looking for sdcard/whatsapp/database instead of data/data/com.whatsapp so it would be awesome if I could set a path
Thank you very much for your help.

Yes its free...windows version is paid but my app doesn't stuck. Mine one is working perfectly. See that you try some other older versions of the app too. Maybe you downloaded the version that stucks at 0% or something like that.

Sorry for answering late :x
Okay, it seems that my root was broken somehow, but now as it works, the program tells me I am not rooted (now I am for sure!) and wants me to download Kingo root or something. But anyway, I had GBWhatsapp installed on my phone, so I think the app won't help me because it would search for com.whatsapp instead of com.gbwhatsapp (could that be possible?)
I found the app Undeleter, this has some more path search options but unfortunately not one where I can specify my desired path. So, I hope you got one last idea?

Can't delete bloatware

Hi guys,
So I just unlocked my phone using xperifix and I tried to delete all the bloatware using 2 apps I found in the play store but I was unable to. The phone just tells me the uninstall failed and i dont even know why
Any idea why this is happening?
thanks

Titanium Backup is possibly the best app for a rooted phone. It will uninstall any app.
You can go into TWRP, mount System partition, then hit the FileManager under Advanced, and then change permissions/delete files/folders accordingly.
But be careful, there seems to be some wierd dependencies going on in there, and you end up with some random FCs here and there after removing bloat app folders and such.
My personal advice if you want to be free of headaches, just 'freeze' the apps using say 'Advanced Tools' from appstore (my recommended app freezer and general swiss-army tool).

Titanium Backup (TiBu) Uninstall Not Working | Oxygen OS 10.3.2 | Magisk 20.4

Hello OnePlus XDA Family. Hopefully someone can help me. I have just received a OnePlus 6 preloaded with Oxygen OS 10.3.2. I have rooted it and I am now trying to debloat it with TiBu but I am not able to uninstall any of the system apps. I receive the following error message every time I try to uninstall 'Cannot remove system app | Failed to locate the apk file.' I can only guess why this would be happening, perhaps it is android 10? the a/b partition thing? Is any one else having this issue? I have searched to no avail. Kind regards in advance
Yes... I do understand your frustration but I can confirm that titanium back up can't uninstall some of the system apps (mainly bloatware).
I suggest you the ADB way using a pc and a USB cable.
Follow this page (it works with rooted or non rooted phones)

Try and let us know
You could use Terminal Emulator Debloater, Swift Backup, or just freeze the apps instead of uninstalling them.
