I Fixed it

A few small things:
Intel should be intel.
Under CPU Optimization:
"Samsung’s CPU is set by default the run at 1gHz."
The should be to.
Sideloading:
"(don’t forget that after you install it from the market you still have to go to your app drawer and run busybox once so it installs)."
Should this be after you download it from the market?
ClockworkMod Recovery:
"ClockworkMod written for us by a developer that goes by the name of Koush"
Missing is.
"This gent puts a ton of work into helping us captivate owners out"
Replace puts with put and Capitalize Captivate.
Changing Your Messaging Ringtone:
"well the ones that matter anyway.."
Extra period.
Other than that, excellent guide. I'll definitely be using it when my Captivate arrives.

Thanks! I fixed all those errors but I'm not gonna upload the new version just yet because I will keep finding more errors so it just seems wasteful. I did not actually write most of the guide myself I just formatted it so there may be some mistakes I didn't pick up on.

i used this guide today and it delivered.

If there was anything you found difficult or anything you would like to change just tell me and I will add it to tonight's update.

Hi,
Thanks for publishing this. It looks very useful, similar to Energy ROM.. But I am very new to Android phones (trying this on Samsung Captivate from AT&T, bought yesterday). I am running windows 7 ultimate 64bit and I exactly followed this guide. But somehow I am still not able to see the sd card. I tried placing the update.zip at Computer\SGH-I897\Phone and shut down the phone and tried restarting the phone by holding the up/down keys as well as power button. But after selecting reinstall packages it said could not find /sdcard/update.zip.. Pls held. Again very sorry if I did some mistake..

The SD card is simply the root directory of your phone. You do not need to open a folder, it is the highest folder you can place it in. Hope that helps

Somehow it was not able to find the sdcard root. Then I realized that you mentioned something called as Droid Explorer, I searched for it and installed it on my PC. But when I opened Droid Explorer, my device was not recognized, then I clicked on link on the explorer window, upon watching that video I enabled the USB Debugging, then I was able to see my device, then I selected connect to my device. After that I saw an explorer but it had empty root and I was not able to copy anything. There was a menu button at the top row named "Transfer to device or Copy to device" I selected that and selected update.zip file and tried to transfer. Something happened but still explorer was empty. Then from my phone Top slide down menu I selected mount USB storage and I started seeing windows explorer on my PC. Then apart from other folders I could see a folder sd in the root. Then I again put update.zip in the root.
Then followed the restart sequence, this time it found the file but exited after Signal 7. It was trying to asert something but could not find the correct model number I guess. My cell phone's model number is Samsung i897.
Please help

I did not write the PC instructions, so I can not help you (I only have a Mac). But the person who did can probably help you his username is systoxity.

Because not enough errors were found to make it worthwhile to update the PDF i will wait till tomorrow to fix the minor errors.

Good source of information
Thank you for putting this together. I am going to sticky this for the time being.

For installing the latest version of busy box, you should include that before the instructions for running titanium backup...the latest version of busybox installed from the market will work with titanium backup so theres no need to have to click the "problems" button...this way you wont have to do the busybox download step twice...should also save a few megs since titanium backup wont have its own copy of busybox installed BTW nice guide

You can also just mount the phone memory using windows explorer and move the file over. I was never able to get droid explorer to transfer the file. It always said it went but then was never there.
Anyway all I did was connected just as I was going to connect to kies but then when windows asked me what I wanted to do I clicked on open file view and dropped updated.zip on my phone.
Only issue that I had with rooting was I accidentally opened the file in windows(winrar). After I moved the file over it found it and attempted to install it but then exited with an error(do not remember exact error), but had to do with mounting. Anyway I re-downloaded file and saw file size was different. After I moved the file over again everything went great. I still haven't removed bloat-ware and such but thats next on the agenda.
Also I was on windows 7 64 bit, saw some other users in other threads saying they had issues connecting the phone. Everything so far has worked great for me
Thank you very much for this handy pdf file!

Somelinks aren't working
First of all I have to say very good guide for noobs!
1. when I downloaded the update.zip folder I didn't work I guess because the name of Samsung captivate is not in the folder or something. So I just downloaded the other file from the forums.
2. Link to CPU optimization doesn't work.
3. I downloaded the droid explorer. It connected to my phone but I was unable to transfer anything. So I just tapped on the USB connected in the notification bar and mounted the phone. This allowed me to use windows explorer to transfer files. I believe one can transfer files by selecting the option of Samsung Kies under USB settings.

I got all your feedback. It will all be corrected by tomorrow night.

Cool guide however the rumor is the GPS only gets turned on when pulling up an App that uses it, so that step in the "battery saving" section might not be necessary.
Also you may want to replace Market Enabler with Market Access. It's a rehash of Market Enabler but also has a Set on Boot option that keeps it persistent versus being reset each time.

You also Might want to add a Tips/Tricks Section..
Here You can put some cool tips like the one i found out about backlight control.

[Q] late night phone spaghetti. x10 mini pro help please!

Hi everyone,
I'm looking for some pointers on the path to 2.1 on my x10 Mini Pro, and hoping the wealth of knowledge between you all can set some things straight for me?
I'll apologise in advance if I ramble at all or don't make much sense... I've been browsing forums for hours and am suffering from mild cross-eyedness and slight brainfreeze.
The scenario;
I have an x10 mini pro, running 1.6, on Vodafone UK. Yes, the ONLY network that have not yet provided the 2.1 update for x10mp users. The phone was rooted with universal androot and also had astro file manager and titanium installed. For about three months I have had the 'starting download' hang problem in Market which I have not been able to fix. I hadn't really wasted much time on it as it was of little importance at the time however I now want to update some things and can't. Today I got annoyed and did a factory reset, hoping to resolve the problem. It didn't, and now I have a blank canvas of a phone.
I didn't back up before doing the reset as call logs and txts are of less importance that the files on my sd card, which remain untouched. I don't really have any other 'important' stuff on the phone right now.
I realised shortly after that I had a backup from December which I ran, as a last ditch attempt, this did not restore my lost applications, but did restore some user data. I noted that my root privileges and titanium were gone too
B*gger it, I thought, since I've lost all my data I may as well go for a generic NON-Vodafone installation of Android 2.1, and hopefully that will also fix the Market issue.
I've had a look on forums here and would like to run the 2.0.2.a.0.24 firmware posted by shivenjuneja.
I've downloaded this via pc, and understand I need to also install the flashtool and xrecovery, both of which I have downloaded and saved in a folder on my laptop.
Now remember, market was not an option so I've downloaded universal androot via pc too and have saved this to the root of the SD card.
With my primitive blank phone, I am unable to browse to it without a file manager, so now I need to download Astro File Manager again.
I decide to have a probably fruitless attempt of doing this via the market (because saving it on the SD card is pointless as I need it installed in order to browse to it!) and much to my amazement, it's worked!! Woohoo Market is working again! But hell, I've still lost everything on my phone so I'll perservere with my android update, thank you very much.
Ok, now while waiting for Astro to download, I remember that I've also read on the forum that the upgrade to 2.1 is likely to be stuck in a booting loop if I upgrade with user data on the phone. If I do a factory restore I will lose my file manager and root privileges that I will shortly be installing, right?
So now, at this hour, I'm wondering exactly what order I need to do everything in to get 2.1 on my phone.
To install 2.1 I need to install the flash tool and xrecovery. To install those I need root, to root I need Astro and before doing any of this I need a phone that has no user data on it.
D4mn you Vodafone.
Could anyone advise the best method to do all of the above i.e in what order to do it all, or point out if there is anything obvious I haven't accounted for.
I don't usually have a problem with this sort of thing, hopefully it will look clearer tomorrow!
Thanks in advance
K

Also, does registering your google login to use the Market count as 'user data' when you upgrade? I ask as I may need to download and install Astro again from the market, if it's still working after another reset?

A lot of view and no replies? I could really use your advice guys if anyone could oblige...
From further reading I understand that I need busybox to install xrecovery and that I also need to be on 2.1 054 as xrecovery won't install on 1.6?
Is this correct?
It sounded so simple initially to flash from 1.6 to the latest version of 2.1, whereas now I need this to install that, need to be on the later version to install the app I need to use to flash to the next version up, and have to have a bunch of other apps and tools installed in order to the able to run anything!
All I want is a rooted 2.1 with all the network and SE bundled crap removed, so I can start putting my phone back to how I bl00dy want it with the apps I choose!
I hate you Vodafone. IhateyouIhateyouIhaveyouIhateyou

Samsung Galaxy Indulge 4G nand lock

I just got one of the new Galaxy Indulge 4G phones and tried rooting it.
BusyBox installer is telling me that the phone is rooted however it is nand locked.
and ideas on how to unlock nand on this phone?

How did you root it?

SuperOneClickRoot.

Yeah i tried adb, super one click, and zroot. None of them worked, and for some reason everytime i try to start up root explorer, it crashes trying to get super user. I've tried all means of forcing super user to get onto the phone. No matter what it wont work. Mike thinks its Nand locked. Another thing i noticed is when I used super one click, i had two options at the top right hand corner that looked like names of my device. I can get my serial number with adb, and it shows it. Another darn problem is no drivers are out for this phone yet. Also have no idea of the LTE chip is interfering with this either. So come one come all dev and droid guru's help us out!

So basically I think this means we a need a custom recovery, flash image and stuff. Bah, that'll probably take like a month

K, also tried visionary rooting, which did some wierd ****. I rebooted and it seemed like i had root, but super user still didn't work. It fooled a couple programs into thinking i had root, but it would not let me "touch" the files on the phone. Even though it claimed I had r/w permission.

The Samsung Epic 4G drivers worked for me, also tried the rooting process used on the Epic whoever busybox says im rooted but that nand is locked, i downloaded Terminal emulator and it says im not rooted, also installing superuser not possible, I was able to install root explorer but not any good if doesnt let me delete the bloatware only read.

Yeah, busybox says the phone is rooted but nand locked.
superuser app was added to system/apps. however im not able to mount system/apps with R/W from root explorer. The rooting process seems to gain access to r/w the files but the apps cant.

seems 4G still have far distance from us...

Supposedly there's a work around for Nand locked, but the first one didn't work for me.
With the absolutely beautiful ADB exploit I use, titled rageagainstthecage (ratc), absolute ALL devices can be rooted. This is because it exploit is ADB which all devices use. There is an issue though. Some devices have a NAND lock which does not allow you to write to the /system mount. Because of this, you can’t copy su, sqlite or busybox to /system/bin. This creates some issues but there is a work around. For things that don’t need access to /system (like enabling non-market apps) I can use the ratc exploit to make those changes. If your device cannot use su in /system/bin then you can simple select a checkbox (as of v1.5) that says to use ratc.

This didn't work still for me. So the only other option was unrevoked, but when I went to the site, it listed only HTC. Kinda confused how using HTC roms is a work around for a samsung phone lol. Still need some master guru's help on this stuff.

I too have been trying and am unable to get nand unlocked, I would really love some other ideas. Anyone out there able to help?

I'm waiting 'till the $50 MIR on the 1st, then I'll jump in with both feet.

Some guy suggested to shell root > perm root > restart device. That doesn't work either. I also noticed something called "media scanner" that scans as the phone boots up, i wonder if that's preventing any modified files.

If anyone knows how NAND unlocking has worked for other phones (and im not just talking about what apps to run or what room to use) please contact me so that we can try a few things out and hopefully get a full root for everyone.

Supposedly Mr. Parker rooted:
http://forum.xda-developers.com/showthread.php?t=803682&page=260
I'm asking him through both post and through private message if he could elaborate. Apparently he had trouble with getting Win 7 x64 to work, but it worked with Win Xp. I'm still not sure what drivers he used, and he said he had it not in debug mode. I tried in non debug, and my phone wouldn't even register. So hopefully he'll expand on how he did it. If not, back to the drawing boards, at least till we get a real pro in here.

Got my hopes up that even though we dont have full root yet, I would be able to get rid of the bloatware.
The SuperOneClick is able to get read/write access and send commands to the phone so I opened Root Explorer on the phone and then rand the superoneclick. As soon as the program mounted the phone with Read/Write I started clicking on the Mount R/W button in root explorer until it showed the app as having read/write access to the system/app directory. I tried deleting the Iron Man app and it said it was deleted successfully.
but then I checked and the app was still there loading root explorer agian then showed that the file was still there and had not been deleted.

Wow you managed to get root explorer to work? Mine just tries to obtain root, and crashes everytime i start it up now. I've tried to unroot, and uninstall and reinstall it. I used Linda manager to view the files on the phone, but like you if i deleted they would return on boot. That's why I think metro or samsung has some kind of media scanner that scans at start up, and it somehow reinstalls files, or prevents root. Can't confirm this yet because super user fails ;/

I've been trying also to get root. Programs often will think i have root access. as far as adb is concerned i do have root access till i dont something that requires it. I've been able to install root manager and look through some files. Im under the impression metro or samsung did install something odd, though im not sure the media scanner is it. Also the phone does not require root in order to install other-market software.

What do you mean programs "think" you have root? You mean you have super user? And what "programs" are you referring to? You can install root manager without a root yes, but in order to put it into "r/w" mode and delete the files from the phone itself, such as bloatware, you need root and Super user access. Most people here I hope are aware that you don't need to root to install "MOST" apps. There "is" apps that require root, and you cannot run them without root access.
Such as:
Titanium backup
Set CPU
Why do I want to root is like everyone keeps saying, to delete all the metro apps, and have "full" manufacturer control over the phone. That's the whole point of rooting. So far no one has rooted this phone PERIOD, or at least shown proof they were even able to. So any info you find regarding rooting please post it here.

Alright, so I tried what Mr. Parker did, and no go. Whether I ran super one click on Win 7 x64 (which was all in admin) or win xp, it would not install super user. In fact I noticed a couple of the files copied from super one click were already on the phone, and weren't able to be overridden. Which may relate to nand lock.

[Tutorial] How To Root Galaxy S 4G & Deleting Fota Files

Rooting Galaxy S 4G & Deleting Fota Files
Hi guys - I wanted to shared with all of you the methods that I used to Root my phone and getting rid of the FOTA files and "Bloatware" which free up ALOT of space.
****I want to thanks "Theshadowman" for the Fota files and to the developer of SuperOneClick, the awesome tool that makes rooting possible.****
Before this fix I was getting the "Internal low space" message.
Let's get started
Programs and Files you will need:
-Samsung Galaxy S 4G Drivers 32-bit: http://rapidshare.com/files/456420295/SAMSUNG_USB_Driver_for_Mobile_Phones_x86.rar
-Samsung Galaxy S 4G Drivers 64-bit: http://rapidshare.com/files/456420354/usb_drivers_GalaxyS_x64.zip
-SuperOneClick 1.7 (To root your phone)
-File Expert (to Unzip files)
-Super Manager (Access to /data/fota)
-Fota.zip (Files that will free up all that space)
Additional Files
-Bloatware (Thanks to Chadster)
http://db.tt/RFzd364
***Note:*** You will find all the files you need attached at the end of this post with the exception of Root Checker and Titanium Backup. You can download those by simply doing a search in the Market.
How to Root your Galaxy S 4G
1- Download Samsung Galaxy S 4G driver and install it. Make sure you know what version of Windows you've got. (I posted links for 32bit and 64bit)
2- In your Phone, Go to Settings>Applications>Development>USB Debugging.
Note: You will have to check USB debugging or else it will not work.
3- Download SuperOneClick 1.7
4- Open SuperOneClick 1.7
5- Under exploit MAKE SURE you select "rageagainstthecage" and then click Root. Let it do what it needs to do Note: the whole process will take between 5-15 minutes
6- Download Root Checker from Market
7- Run the test and it will confirm you that your phone is Rooted
How to Delete Fota files
Step 1: Download all three files in your computer and send them to your email and open them from your phone.
Alternative method: Download them directly to your phone.
Step 2: Install File Expert
Step 3: Install Super Manager
Step 4: Open File Expert and navigate to the directory aka folder that you downloaded the files to.
Step 5: Press and Hold the fota.zip file and select Unzip files
Note: File Expert will unzip files by default in same folder.
It will create a Fota folder with two files fota_delta_dp1 and fota_delta_dp2
Step 6: Open Super Manager and then open setup and check the "Enable ROOT function" then press menu on your phone and switch to r/w (stands for read and write)
Step 7: Navigate to the folder where you have the 2 Unzipped fota files (fota_delta_dp1 and fota_delta_dp2)
Step 8: Select both and cut them
Step 9: Navigate to /data/fota and paste the 2 files in this folder
Step 10:Reboot phone and WAWAWIWA! between 150mb-300mb of free space
If you want to get rid of Bloatware - Download Titanium Backup from Market open it and uninstall every app that you don't need.
Warning: Becareful with what you uninstall.
Hope this helps and let me know if have any questions.

damn dude that worked! thank you, this helps the phone a lot right?? Hey man I was also wondering if you know a way to fix the lagging for this phone?? I've heard of oneclicklagfix thru superuser once u root the phone, but I can't access it because, like I was told not too long ago, there isn't a oneclicklagfix available for the sgs g4 right now. any pointers? thank you

Worked perfect. Have 400mb free. I'm also wondering about the a lagfix for this device.

now you've tried using that titanium backup app...now how would you know which bloatware you can removed and which you can't.

Just in time omg!!! Lol just got the galaxy s 4g today for $280 ahhhh yeahhhhh!!!!!!!!!!!!!!!!!!

Its safe to say that if you didn't read about a lagfix in this forum, then there is none yet. I would only attempt tools for other phones if your an advanced user.
If you have the bloat zip file, use that as a template to delete apps. Im not that experienced.

If you use the paid version, you can freeze the app first to see if it causes any problems.(trust me, it's worth the money)
If not, just do as fknfocused said. Download chadstet's bloat zip (in the themes and apps forum) and use it to see which bloat can be removed.
But it is pretty basic. If it ooks like 3rd party software, just rip that sucker out of your phone.

I'm glad this helped. No lagfix yet for this phone, but once you get rid of all the bloatware you should experience less lag. I'm pretty sure it will come out but I am giving it time.
Here is a list of apps i have removed and haven't experienced any issues after deleting this apps:
Folder organizer
Kindle
Amazon mp3
Double twist
airsync
facebook

T-mobile tv
video chat (qik)

y! finance clock

I have 328.23mb available on my Internal memory.

Awesome thanks for your help, I hope the lagfix comes out soon.

No problem man, Glad to help.

Dude I was fine until I got to part where I have to paste the files in the
/data/fota file. I cannot locate it how do I find it.

In super manager go to setup and select "Enable ROOT function" and then press the back button of your phone in super manager and then you will see the /data/fota make sure you are not in /mnt/sdcard/data. Let me know if you still need help

I'll try this when I get home thanks.

Thanks a million
The fota.zip rocks! It was driving me crazy that I was removing the bloatware, but not gaining any internal storage. It went from 24M to 356M after your fix. Thank you, thank you, thank you.

If we replace the fota (firmware over the air) are we not going to be able to get our firmware updates over the air?

Quite likely, without restoring them, if you've used the space freed for something else.
The files aren't really replaced, but the "placeholder" files that reserve space for FOTA have been truncated to zero length.
Removing the files completely will likely allow them to be regenerated, assuming you have cleared the space for them on the internal storage, should you want to get any FOTA (which, unless you're running stock firmware or are a dev and need the new firmware, is an open question).

=D my memory storange application space is at 318 mb now =D

this is awsome! great walk though. i wish i had this a month ago when i got this device but i had to search and learn and ask questions before i got 310mbs free! even though superoneclick 1.7 to root only took me like 2 mins. for anyone wanting more from there phone this is the way to go. im still running stock with Launcher Pro Plus.

I've deleted some important files by mistake and I would really like to recover them.

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.
Thank you for your help! I will wait until someone may give me a solution, or a possibility for a solution.

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.

Thank you very much for your help. I understand: I must give up. But the most important thing is to learn something about anything we do. Anything could help for future situations.

Thank you again. Goodbye!

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...

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.

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.
