sorry for my question but wanted to know if anyone can help, 7 days ago bought a acer stream, I made the root and then exploring delete files by mistake apk system, of course, many things do not work now. If anyone can help they would appreciate a lot. Thanks.
You're pretty much out of luck. If you deleted the files 7 days ago, they are likely un-recoverable. If they are on the sd card, and less than a day or so, you have a chance to recover them using GetDataBack.
Your best bet is to do a factory reset to get all the files back.

remove them from the system and are apk files, there is no method to revive my acer?, it means that I throw it, only serves, I can not load a new rom?

grab this dump and extract the files you need and put them back where they belong

thanks
these are the files I needed but when I try to run with the browser gets me close to applied force and will not let me run it. There is some solution to this?
Factory reset the phone. If you cant do it via settings, try recovery menu.

I tried to start from the menu, I did restart buttons and no screen goes black and does not reset to factory settings with some other idea?
Hello, I have a question I hope you can help me with...
I've got a nexus S 2.3 and Ive just deleted a very important text msg thread, have I lost it forever or is there anyway that I can recover it??
If I can recover it can you please tell me what I should do as I ve never done anything ike this before. Many thanks, concerned android user.
Never tried anything like this before, so just some ideas as a general outline:
The first thing you should do is a complete image of the phone before the data can be overwritten (if it isn't already).
There is no convenient way to undelete that I know of.
I would search for the sms database file and try some sqlite tools on it. Look if there are entries that are marked as deleted or something.
If that doesn't bring anything up, I would use a good (hex-)editor to extract the strings from the file and see, if the data is somehow still there.
Anyway it will probably mean a lot of work, depending on how many sms you have stored and the best you should hope for is that you can manually reconstruct the thread in a text file or on a piece of paper.
Hello cgi,
thanks for the reply with advice!!
what is a complete image? how do i do this?
how do i search the sms database?
where do i get hex editor from?
do i need to back up any data before trying to recover anything?
many thanks,
Ray
what is a complete image? how do i do this?

An image is a complete copy of the data on the phone. The easiest way to do that is to use a custom recovery system like clockworkmod recovery. If you have a custom ROM installed, chances are, that you already have it.
First: Is your bootloader locked or unlocked?
Second: Which version of Android exactly is one your phone?
If your bootloader is unlocked, you can install a recovery image that will let you backup the data partition where your sms database should reside.
If your bootloader is locked but your Android version is 2.3.3 or lower, you can use an exploit that let's install a different recovery image.
If your bootloader is locked and your Android version 2.3.4 (and your phone is not rooted), then AFAIK you are out of luck.

I don't know in which files your sms are being stored, but it should not be that hard to find out.

There are a lot out there. I use okteta from the KDE project, but you can use whichever you want. You could use notepad, too, i guess, but that won't make things any easier.

That's the image I was talking about. You would first copy all the data on your computer.
CGIi,
Many many thanks for taking the time to reply to my question!!
I dont think there is much chance of recovering this thread, my friend has about half of the 900 texts in the thread which makes it slighty easier to swalow.
once again the importance of backing things up is key to keeping the pics, files, texts you want to keep. I'l try to do this even more in the future, I'm so sick of losing data from old mobiles, PC'S etc, I'm gonna back up everything from now on!!
Many thanks again, RAY
[INFO] [QMV7B] [ELLIPSIS 7]
1. My apologies if this thread is in the wrong forum.
2.Not sure if my thread title is OK.
3. Am I allowed to post my link?
4.This site looks different and I can not seem find my answer.
Hi everyone, long time viewer first time poster in need of help. I recently deleted my system apk due to bad judgment,please don't judge. I can no longer access my system settings and with that the package installer no longer works. My tablet has been rooted, for a bit. I used the (kingo root) successfully.I do not have back up, I did find and download the apk sys files from a upper mod and now I need to enable via command to change the setting to allow installation of unknown sources .I do not know how to do that,. I am guessing that maybe that will FIX IT (crossing fingers). Any of the more experienced users know how to assist? I would love to have the stock rom, can't find it. Maybe there is a different method to do a complete restore that has all the files. My apologies if this is redundant request.
oh, I have already tried the hard factory reset and the system setting is still missing. I can't return, No warranty
Thanks in advance, and I can now stop the ugly crying.
I have the QMV7B ELLIPSIS7 4..2.2 rooted via KingoRoot.
thanks to (?) can't find your name.f for the link for system files I have.
I have a qr code on my photo albuma and my profile pic for the qmv7b system APK.
Hello,
I hope that this is the right side of the forum to describe my problem. I desperately need help. It's a long story:
I had on my Samsung phone the app of "Chrome", which I always use to surf the internet. Using the google browser IN THAT APP, I have downloaded lots of things (I'm a scholar, so I like to read and I use to download everything that I found interesting). I have updated the app and I was frustrated, because I couldn't take anymore screenshots while surfing in "incognito mode". So, I decided to delete the update: i went into "settings", then "apps", and then I have brought back the app of "Chrome" as it was when i bought my phone. Sadly, I then noticed that I had lost every file in my download folder; I had lost every file downloaded with that app.
I had not synchronized my Google account, I can do no backup. I'm so angry and sad because I've always thought that the files downloaded would have stayed in my phone until I and only I would have decide to delete them.
I have done a lot of research on the internet and I have found out that there are some apps that can recover a very large part of lost files. But, in order to do this, I have to root my phone.
My phone is a Samsung Galaxy J2 SM-J250Y/DS, and the Android version is 7.1.1. I have seen that rooting a phone could be very dangerous; also, to me is very complicated. But there is a program called Kingoroot, which, once installed on my computer, could (it's a possibility, I know!) rooting my phone easily.
What should I do? Should I try the rooting method? It seems to me the only way...
I ask you any suggestions... Please help me. I am a depressed student that, in this life, can only enjoy reading and books...
(I am Italian, and I hope my English is understandable. If I did any mistake, please forgive me.)
Sorry can't help you get what you lost back... I feel your pain.
After losing thousands of bookmarks over the decades I started using Colornotes to save my important bookmarks.
You can save the hyperlink with a title, color, and whatever text you want to add. If you punch the hyperlink it opens in the default browser.
The app allows you to save it's data to your sd card which you can backup on your PC.
Use ApkExport to make a loadable copy of the app to future proof it.

Thank you very much for your reply.
But... If I root my phone, and if the rooting is done without any damage, is there a possibility to get most of my files back? Or, even if I root my device, I will never be able to recover them?
It sounds like it deleted the data when you rolled the apk back (to factory load?).
If so it's going to be very sketchy at best to recover them.
I guess history's been deleted as well?
There are many coders here that have far greater knowledge than myself with Chrome.
My understanding of rooting is very basic as with Chrome which I rarely use.
If no one else replies in a day or two, bump it back to the top. Hope you find a work around solution.

Rooting Android by means of TWRP and/or Magisk ( keyword: SuperSU ) affects its /data partition where phone's data typically are housed. Therefore it cannot be excluded that data stored there is overwritten and can therefore no longer be restored.

Is there the possibility if deleted that it's still on the system cache and is there a way to recover it if so on a none rooted phone?
Maybe using ABD?
Don't some on the "one touch" root solutions claim to preserve the data?
Android doesn't have a recycle bin thus nothing gets cached. Deleting a file means nothing else than marking the space it occupies - whereever this disk space is located - as usable so that it can be overwritten by the system.
Have never used a "One-Click-Root" utility ...

Yes, it's just like I told. And yes, even history has been deleted.

Yeah I was aware of the overwrite issue but on an unrooted device I don't think you can access the system cache. Even if you could the data could be so juxtaposed from lose of file structure as to be unusable.
One-Click-Root worked on older versions of Kitkat allegedly.
So... I understand. But I want to try. I want to root my phone. But I have to know how and I must prevent my phone from all the risks.
blackhawk: you said that the "One-Click-Root" method worked only for Kitkat Android. But I have read here that with Kingoroot i could have a chance:
How to Root Android Nougat (7.0/7.1) | KingoRoot Apk
Root any Android Nougat 7.0 7.1 device with KingoRoot.

(It's important: I AM NOT SPAMMING Kingoroot, I just want to understand If I can trust what it's written in their site. Also, in the link, at the end of the page, there is written that I can root my phone with my PC, which, to me, seems a safer way. It's the main idea I had when I decided to write in this forum, because I wanted to know the opinions of people that are very able to use these methods and these kind of programs.)

You can try it; it will either work or nothing will happen. Even if it works it's likely those files are gone. Maybe better to chalk it up to another lesson from the University of Hard Knocks.
You could try contacting Google tech support to see if they have any ideas.
The last AT&T firmware update was specifically to block easy rooting by Kingroot; the rats learn quick.

Hi, I would suggest you can try free tool for Android Phone such as Stellar Data Recovery for Android which easily recover deleted files like, photos, audio files, videos files from your Android phone internal memory storage.
Source: https://www.stellarinfo.com/media-tools/android-data-recovery.php
{Mod edit: Quoted post has been deleted}
That drfone again. Scamware.
Do Not Use.
Drfone if used will encrypt "recovered" data and ask you to pay for it. After which the original data is gone leaving only the encrypted copy.
It is not free... not to be trusted!
Ran into this scam many years ago.
Found my old phone from high school. Turned it on and looks like I never factory reset it, and I would love to see all of the photos and messages I left behind, however I can not for the life of me remember the pin I used. Browsed around and tried to delete the gesture.key using ADB but permission is denied, and I wasn't able to find a custom recovery tool for this specific phone either. Anyone have any possible solutions? Thank you

If you cannot remember the PIN, you're most likely going to have to factory reset. There is no way around this that I know of, unfortunately.
you can just dump the whole userdata partition off flash memory in EDL mode, loop mount partition image from linux and modify it's content (like deleting locksettings.db)

Hi there, thanks for responding to my forum post. I can give it a shot, however I was wondering if you would be willing to help me with attempting this. Im familiar with root and devices but I’ve not had any experiencing with dumps or tools like the one you provided on github. I have an extra ZTE Flash to test on but some extra insight would be nice. I also had two questions:
1: can I just take the locksettings.db and somehow retrieve my pin from it instead of modifying and dumping?
2: if I do end up having to dump, will the environment be the same (IE logged in apps, id like to see my message history in apps that are there)
Thanks so much, and sorry for disturbing.

you need a firehose programmer matching your SoC and OEM. the tool comes with collection (loaders) for quite few devices, just give it a try.
1. might be possible with password.key
2. yes by just deleting locksettings.db nothing is changed
