How to know the BGA (ball grid array) type of Huawei P20 Pro ?
I ask this question for a data recovery purpose.
I've asked the question to Huawei, but so far, it seems to be difficult to get an answer from them.

Hot air it off and see...

I think I found without disassembly !

You thinking of trying to drill through the pcb to access the pads?

I don't think about anything, a professional asked me to try to get this kind of information in order to try data recovery. I don't know if it's possible and don't know either how he wants to proceed. The only thing I know is that the phone kept the photo data (what I want to get back) probably not encrypted.

Good luck... that's the hard way to backup data.
Personally I would write it off as KIA.

What is KIA ? I will try to get info about this.

Lol, killed in action. A military term.
In general data recovery is a lost cause to a greater or lesser extent, generally the former though.
Always redundantly backup critical data to at least 2 hhds that are physically and electronically isolated from each other and the PC on a regular basis.
Use a SD card as a data drive if the device has that capability. All critical data goes there, only the apps, dcim and download folders go on the internal memory. Then backup the SD card.
It gives you more protection from data loss if the OS crashes or if the device is damaged. Quality SD cards rarely fail. More layers mean more chances to prevent data loss.

Ok thank you ! I usually backup my data twice, but here the phone wasn't mine, and most people sadly do not backup their data.

Some need to learn the hard way. Androids tend to be very stable and reliable if set up right. Unfortunately things however rare do happen...

sdcard, encryption, backups?

I wonder if the encrypted sdcard access will be exactly like wp7.....
if the phone is damaged, and all my files/pictures have not been mirrored yet.....
can I still put the card into a reader and get them off?
I watched another thread and it wasn't clear if card access and encryption will be as restrictive as it currently is. a damaged touch screen alone could mean allllll my pictures would be gone, as there is no way to access them.
I know about syncing, but that doesn't always happen 5 minutes before someone drops their phone at a wedding
At least by what we heard it seems that the phones that do have a SDCard-Slot will use regular SD-Cards - that is to say: FAT formatted so you should be able to take it out and use on your PC. What we don't know yet is how data will end up on the card if you use it on the phone. I guess there will be a setting allowing you to store pictures/videos on the SD-card instead of in the phone's memory but you won't be storing App data there as at least in the Leaked SDK some time back Apps were only able to read from the SD-Card but not to write to it.
hmm, sounds like real phone backups still aren't going to be possible.
sigh
Given that Microsoft was specifically looking for people to improve the Backup experience and that there are at least some Cloud Backup capabilities that were leaked I actually believe that we will see much improved Backup possibilities - this has nothing to do with the SD-Card support. But as we don't know any details yet I did not mention that.

cloud backup has very little appeal to me. an imaging of the phone to sdcard is simple, effective, and easy enough to encrypt if security is an issue.
why Microsoft is opposed (or hasn't thought of) simple sdcard backups is beyond me.
I can't imagine waiting an hour ( and the data used) for a cloud solution to mirror a persons phone from a damaged phone to a new, undamaged device.

Greetings, is there a benefit for rooting your phone in order to recover pictures after factory reset?

My wife's phone accidently got wiped clean due to factory reset, she had lots of photos of her dying mother without proper backup.
Unfortunately she has US note 10+ and it is snapdragon and can't be rooted, I found a person in this forum who was able to enable the bootloader despite Samsung removing it.
Will rooting the phone give better chances for recovery software's recover images and videos before the factory reset?
Thank you for your time people.
Is it possible it was backed up by Google or Samsung cloud?
Otherwise I would say it's unlikely.
Loading anything onto the phone could overwrite any data left. Turn off the phone until you decide what, if anything can be done.
It may be possible to directly access the chipset's memory internally. You would need an expert for that if possible.
Run it by Samsung as you aren't the first with this issue. Getting upper tier tech support ie a real engineer will be tough, be persistent. A letter may work better. You may get lucky and they'll ask you to send it in.
In the future get and use a SD card as a data drive for the 10+. A V30 .5 tb Lexar card is only about $75. With data, backup is the only solution most times. Make sure to backup the SD card data as well to the PC and at least one other stand alone hdd.

Question Recover photos after factory reset

Is there any way to recover photos after factory reset?
Phone is not rooted and no backup was taken before the factory reset.
Thanks.
Sorry to not be helpful, but I hope not!
Tough luck if that's an accident though....
Maybe someone can help you better lol.
Write a nice thank you note to Scamsung for removing the SD card, one would normally save the pics and data that shouldn't be wiped out on external storage.
I personally have not come across a user friendly solution to recover the data after a partition format...there are forensic methods to do it, but... $$$

What a BS, if you do a factory reset you should backup your important stuff. That's not Samsungs fault. (childish to say Scamsung for that). Use google photes, a USB stick, a NAS, copy to PC , Use DEX etc etc..

Correct, it's not Samsung's fault however if the user had the MicroSD it's much more likely the problem didn't arise. Not having MicroSD on a huge, expensive device is a sin, they're getting blow back everywhere you look.

I mean, I sorta agree with the OP here because Samsung has had their game backwards at one point with this issue. Or, perhaps it's just my particular phone? Anyway, I literally made the same "mistake" a few months ago (as I knew that Google Photos was still backing up my photos - so I'd be all good anyway). But after the full wipe and re-flash, somehow all of my photo files were still there... So at the time (I doubt this is still happening now), the S21U's factory reset along with the choice to delete files didn't touch the phone's DCIM-->Camera folder, lol.
So if anything, perhaps the OP was using Odin...? But if that was the case, I suppose they would've known to backup their photo files first...
As I know, we can recover photos after fatory reset before they are overwritten by pro data recovery software without backup. So first we need to stop using your Samsung phone. About the data recovery software, you can search online. Good luck to you.

SM-N986U1 5G turned into brick

I put phone into overnight charge and had a black screen of death in the morning. Needless to say that I was taking better care of the phone than of myself Good news it was still under warranty, bad news motherboard has to be replaced so all of my info for the last few years is gone. Since I never backed it up, ALL except for pictures on flash card goes into garbage at Samsung repair place in Texas. During the past month phone acted strange 2 or 3 times started freezing for no reason I guess it was THE SIGN that it turns into typical Note 4 soon. Had faith in Samsung since Note 2, Note 20 blew it, oh well.
It should be rock solid stable. When you see behavior like that many times it's the only warning you get before a crash and burn.
You have a SD card slot, why weren't you using it as a data drive?
All critical data goes here. Only loaded apps and the download folder should be on the internal memory. The DCIM files should be transferred to the data drive regularly. After downloaded files are vetted they too are transferred to the data drive to be archived.
The data drive is then redundantly backed up to at least 2 hdds that are physically and electronically isolated from each other and the PC on a regular basis. Never clone or compress backup files as it will damage some file types/data bases especially media ones. Never encrypt or password protect backup data as you are the one most likely to be locked out!!!
You need to implement a well thought out, comprehensive plan to prevent data lose in the future. There are only two kinds of PC users, those who have lost critical data and those that wiil... been there, done that... a whole data base spanning years
I have over a dozen backup hdds in various locations. I also use a .5tb OTG flashstick for "dirty backups" of my SD card. The PC I use to copy backups is always offline from the internet to help prevent malware breaches. Hdds should be stored in a cool, dry place preferably in earth grounded metal boxes ie a safe or ammo can preferable wrapped in antistatic bubble wrap or the hdd's original plastic shell if it had one.
Try asking, begging Samsung to do data recovery on the old mobo, you might get lucky.
They have the capability at some level to do so.
Going forward never put yourself is this position again as it is a painful reality. More lessons from the school of hard knocks... meh.
Yes 512Gb flash card almost empty. So what program for data drive/backup would you suggest?

I manually cut/paste everything. I don't like surprises. My file organization has evolved as a direct result of this
Never have just one backup copy... you will get burned.
If you find a reliable incremental file backup app that can cross platform with PC let me know.
The holy grail...

Question Do I need root?

Hi All, long time user of XDA forums but havent had to root a phone in a while.
I deleted some pictures in error from my phone yesterday and am desperately trying to figure out a way to get them back. They dont appear in the recycle bin and they dont appear with a standard file search app, thousands of pictures do but not the ones I deleted.
Apparantly I need to root the phone to get better access rights to do this, but am I right in believing that rooting the phone will delete everything anyway?
Any way to do this please? I really need some help with these important images.

Don't try to use trashware like DrFone.
The internal memory is encrypted by default so if you lose that encryption key for any reason you are boned.
If you can use adb to access the unused portion of the drive, that may work.
Using ADB in recovery mode - recovering files from a locked phone
Hello, here's my problem: I accidentally put a schematic as a code on my phone that I immediately forgot. Now that I only have access to the lock screen, I can't put my phone in file transfer mode because I'd like to retrieve it before resetting...
forum.xda-developers.com
If you are successful know that the folder structure has been lost. The jpegs will be disassociated from their exif data, time stamps, image numbers, etc have been lost forever.
Using that phone at all may overwrite the data as it's now free space for the system to use; power down the device until ready to attempt recover.
Backup all data before you begin whatever you attempt!
Personally at this point I would have written them off. If you do recover data, you'll understand why. In the future use a gallery that has a trash bin if possible.
Redundantly backup critical data to at least 2 hdds that are physically and electronically isolated from each other and the PC. A OTG flashstick can be used for quick "dirty" backups. Don't use as a primary backup.
If you can mount your phone on a PC using a USB cable, you could try a PC based file recovery program. (I honestly don't know if it would work over a USB cable, but no harm if it doesn't.)
Be careful where you get the recovery software. There are lots of people willing to promise the world, take your money, and blame the file recovery ghods when they can't recover squat.
The one I'd try first has the worst user interface, but it's free and has saved my butt more than once. It's called PhotoRec. (It's packaged in with a drive recovery program called TestDisk.) PhotoRec supports a bunch of Linux/Android disk formats (many only handle FAT and NTFS variants, which won't help you). Just be sure you read the instructions and be sure to direct the output to a dedicated folder on a drive different than your phone.
TestDisk Download
Download TestDisk & PhotoRec. TestDisk is a free and open source data recovery software tool designed to recover lost partition and unerase deleted files. PhotoRec is a file carver data recovery software tool.
www.cgsecurity.org
I just noticed that PhotoRec finally has a Windows based GUI implementation called QPhotoRec. Same download location as I mentioned in the previous message. But should be a fair bit easier to use.
Note: If QPhotoRec can't see your phone on the USB cable, you might still want to give PhotoRec a try.
One last note... As long as you continue to use your phone, it is still writing things to the drive that holds the pictures you want to recover. If the phone happens to overwrite the place the photos sat on, they're gone forever. So it's best if that you power off your phone until you can make an attempt to recover the photos and you move quickly to make the attempt... Good luck.
After the recent dumping of Samsung Cloud and the forced migration to a Microsoft cloud drive,I lost a bunch of photos from my alternative device (I had 2 phones and 2 Samsung Cloud accounts- but the changeover couldn't handle the 2 account bit, both phones ended up with the exact same data) and I tried several methods to recover the lost data and eventually had to give up. Good luck.
Relying on cloud to backup files is crazy. Keep a couple hard drives/usb drives for that.

Cloud backup is safer than keeping a couple of hard drives and usb drives. By design cloud storage is replicated a minimum of 3 times across 3 regional data centres, each having multiple copies on distributed storage with multiple backup services and UPS.
Your data is not safer on two USB drives vs a Google data centre. Do you keep them in fireproof and electronic magnetic proof safe? If not then your backups are not protected at the first step, physical protection. Do you cycle the hard you use, change the drives regularly so that there is no chance of hardware failure, do you consider MTBF rates of the devices you use? USB drives have a limited number of writes so using them too much may risk the data on them. Do you use multiple off-site safes? If both are in one place and there is some disaster (building collapse, or fire for example) then you've lost your backups. Each site needs a fireproof/EM proof safe which adds a huge extra cost.
did you check the trash folders?? usually deleted files stay on for 30 days unless physical deleted from the trash like windows

What app did you delete the photos in?
Each app will have its own "delete/recycle" solution. For example, if you delete photos in Google Photos they are kept in the "Bin" for 30 days. If you used a file manager it may have a recycle bin or may have permanently deleted using write over to provide a true delete function.
Rooting like years agao
I am cool with what i have now
Yes you do for acces to internal memory
