Need help getting my phone functioning again - Samsung Galaxy S7 Edge Questions and Answers

I sent my phone to a Samsung Repair center because the Home-Button didn't work anymore (Fingerprint recognition worked, just no press-down function)
After 3 days I got an e-mail saying they are returning the phone because they ran into software issues. Seeing as my phone was out of warranty I was running TWRP and the Superman Rom, without issues mind you. However, Being a Samsung Repair center, they are forced to wipe phones before working on them. I have no idea what they've done but it's stuck in a software-less bootloop it seems.
So now I've got my S7 Edge back, stuck on an infinite Samsung load screen, TWRP seems to be gone and when trying to put the phone into Download mode the Volume up/down buttons stop functioning.
When messing about with different combinations of buttons, I am able to get into a very basic-looking recovery menu titled 'Samsung Recovery' I'm able to browse through the options using the Volume buttons but i cannot use the 'Apply Update from ADB' or 'Apply Update from SD Card' functions due to error: 'Update from external storage is disabled'.
Moving on to ADB, I can see my device in Sideload, but I cannot use command ADB REBOOT RECOVERY, it outputs error "adb reboot recovery error: closed"
I've tried the Samsung 300k tool, but it does not recognize the S7 Edge. Also Odin does not see my device as connected, I've reinstalled the samsung device drivers, done a few reboots, etc.
So... How do I install TWRP or any other bootmanager without being able to use the volume buttons in the recovery menu?
Also, since I'm able to use the PWR+Home+Vol.Down combination, I wonder if they did actually fix the home-button issue.

Vibrant Locked Out

So, dumb self made a pattern that I don't remember. So my Vibrant is at the Too Many Pattern Attempts screen. I've tried to wipe the phone using vol up and down plus power but that doesn't remove the too many attempts screen at all. The only gmail account that I hooked up to my phone keeps telling me that something is incorrect yet I can log in to my gmail fine from my computer... What can I do? I tried to do Odin, but vol down plus power does nothing on my phone. It just continuously power cycles... When I boot into the recovery screen I can use Odin but it just hangs at checking files... Any suggestions?
Do you have coverage? Maybe the Google verification can't connect. It always worked on my myTouch and once on the Vibrant.

Tmobile Galaxy S pattern locked out, can't root
I just bought my first Android device, the Samsung Galaxy S from Tmobile from the US (I live in China) last week. I have only used it a few days and my girlfriend thought the pattern lock would be a fun game to play. Result - locked out. I have the same problems as in the below thread:
http://code.google.com/p/android/issues/detail?id=4784
I tried the receive a phone call then hammer the home key; emergency call and go to search and many of these type fixes; however none have gotten me through. It seems they fixed the security problem here but didn't fix the username password problem as I'm sure the credentials I entered are correct and I have data service.
After giving up on these methods I tried doing a hard reset. BTW, on this model you must hold down volume up AND down buttons at the same time, then press the power button to get the reset screen.
I have cleared user data etc, but when I try to reset the phone I get the error message "setup.zip not found".
I understand that I now need to root the phone, so I tried the method explained here but without having access to the phone I need to load this setup.zip file on the SD (not the one with Avatar).

I already installed Kies (has Outlook sync functionality!) on my desktop so that I can access the internal memory as an external drive. However the phone's USB mode must be set to (it will prompt whenever I connect) to Kies mode. However since I am locked out of the phone I can't tell the phone to get into Kies mode, therefore cannot access the internal memory, therefore cannot load setup.zip, therefore cannot root, therefore cannot get past the pattern lock screen = useless phone.
I need to root the phone anyway so I can load a few Asian IME's that didn't come with the phone so don't mind playing with this, but since I'm new to Android it may be a while before I can get through since most root instructions either require access to the internal memory via my computer or access to the phone (past the pattern lock).
If I offer to make a paypal donation could I summon the help of one of the more experienced Android gods that frequent this forum that can help me get through this?
To use odin you need to get into download mode not recovery mode (Volume Down+ Power) but since for some reason that wont work for you, you will have to do something involving the android sdk do you know how to use it?

On one or two tries, when the device was attached to my laptop I got a yellow on black downloading screen but had no idea what it meant. How does this help me root it? In general the volume down+plus power button didn't do anything but reboot it.
I just downloaded the SDK last night for the last time and haven't succeeded in installing it so have still got a bit of learning to go before I can make it useful.
I have the phone back in my hand now so adding some details:
Holding volume up and down and the same time, then pressing powere gets me to the "Android system recover <2e>" screen with four options:
Reboot system now
reinstall packagages
delete all user data
delete cache data
I've tried all and none will get me out of the username/password screen after reboot. If I select "reinstall packages" it says:
E:can't open /sdcard/update.zip
(No such file or directory)
Installation aborted

[Q] Flash I9505 without going in download mode?

Hi,
I've got my good old 9505 I bought right at release on which the Volume UP button (or more likely whatever hardware it's connected to, as the button itself works perfectly normally) has become stuck pressed.
That causes a little problem - I can't enter Download mode anymore (Normal power up enters recovery due to the stuck key, Vol Down cancels Recovery and boots normally).
I had a custom ROM and recovery on it, and in order to send it for repair I obviously want to put it back to stock status, so I have reflashed a stock MI8 image I found using ODIN, using the custom recovery's "Reboot in Download mode" command.
Now the problem is I have bad luck and likely had an incompatible modem, and after booting even with cache/data wiped I have the Samsung keyboard crashing constantly and WiFi won't work.
Of course restoring the stock image wiped my custom recovery, so I can't use the same trick to get back into Download mode and reflash another modem.
I can't use Mobile ODIN or reboot menus with a "Reboot Download" option, as those requires root, but... rooting needs Download mode.
I can connect to Kies, but for my region it unfortunately says the current ROM is already the latest.
Does someone have an idea I didn't think about?
is there a way to reboot to download mode via usb debugging?/adb shell or something like that?
I found something that suggested it, however while I've painfully been able to go enable USB debugging (with the UI that locks and the "Samsung Keyboard has stopped" messages that appear between nearly every tap) adb devices returns nothing. Maybe the same issues cause debugging to fail too...
make sure that all instances of kies are stopped and also try reinstalling the drivers?
OK, found an app called "Kingo Android Root" that works from the PC through adb, and managed to root it again. It took some time to connect, but once it did it went through the procedure OK.
Then I could transfer the apk for "Quick Boot" to the phone through MTP, and its reboot menu worked to reboot in Download mode
Got a new modem flashed, and WiFi is back. The Samsung keyboard is still crashing every 5 secs, but I'll just try reflashing the OS, never know...
now that you can get to download mode, you can just restore everything back to stock? no? should fix any fc's you're getting, unless they are related to the physical fault with the volume up button being stuck?
Yes, it's just a matter of finding the right stock ROM... :\
OK, the MKF ROM for my country I found here works perfectly fine.
Issue closed then, hope this will serve other people who might end up in a similar situation
Now to see how the service center reacts to a stock config but with Knox flag set...
good luck, and don't forget to let us know how you get on with the service centre/knox situation.
Good news, received my S4 after a one week turnaround (shipping included), and it was repaired under warranty even with the Knox bit set and me having dismantled it (thanks Sammy for not putting "warranty void" stickers, pretty much the first manufacturer I see who doesn't!)

How to boot LG Leon into recovery?

I've successfully rooted my T-Mobile LG Leon, and I've successfully installed TWRP, but for the life of me, I can't get the phone to boot into recovery. I can RE-boot into recovery from TWRP manager, but I can't actually boot into it from a fully powered-down state. I've tried every combination of the power and volume buttons I can think of, and nothing ever works. Download Mode works, the factory restore menu works, but I CANNOT get into recovery. Is there a very specific set of instructions anywhere that I can follow?
EDIT: Okay, I finally figured it out: You need to actually select to do a factory reset, and it throws you into the recovery menu.
Yeah, it was because the stock recovery doesn't exist as a menu, when you're running stock and enter the adb command "adb reboot recovery" it will reboot to the "factory reset mode" and the actual file of this mode is stored on partition named "recovery". Choosing the factory reset option boots the custom recovery because it replaces the said " factory reset mode" and that's the trick.
You can access recovery from the powered off state by holding volume down and power on until you see the lg sign. Without letting go of volume down, depress on the power button before clicking it back in and holding both buttons in until you see twrp pop up.
If you reboot to recovery now, it''ll probally say secure booting error. Simply go to the Developer options and enable OEM Unlock and that'll make you boot to it
You boot in the download mode by holding the vol up 10 seconds and during this 10 seconds you insert the usb. The LG Leon brand screen will come on a minute then it will go into download mode. It says not to unplug until firmware is done updating. So I guess you should have your custom recovery or whatever before you do this. I have only got this far, and thusly it sits. All Dressd up with no where to go...haha

can't find "enable OEM" at all in developer options. have phone hooked computer, and on, it's sending and receiving. No OEM. Isn't there.
See, I'm trying to root this without using KingUser. Since I found that it was pretty easy to do from the very beginning with Samsung, and I just don't see any way to do it here. I can't get ADB Devices command to see the phone.

I got a good way to get it rooted with SuperSU. Ran a command window script I found out there. It worked and now I have SuperSU root. I also figured out how to get into recovery. It looks as though my phone is not the standard LEON that people are talking about here. It's got a few designations, and the T Mobile site advertises a Leon that seems very similar and is called by the name most are using..
Anyhow my LG Leon is designated as a H320. It also carries a v10 desiganation, v10b. The v10 is variable from a-h or a-i. It would seem that once it is updated to 5.1.1 android it gets upped, and becomes unrootable. Mine being a v10b was rootable, but it took me a while to get used to it, and make the command window work.
Unfortunately for me one of many things I tried before getting it rooted, was ADB fastboot. And since this told me to wait for too long, I pulled the plug on it and pulled the battery to get back into "normal" operations. Perhaps I should have waited, because after finding out a few things about the phone, I discovered the true way to get it into recovery:
The real way into recovery for my phone, is to (from power off state) hold the volume up, a few seconds, then plug the USB cable which is going to the computer into the phone. While holding the volume up until it comes to recovery. This will activate the recovery, (Now for me it activates that fastboot command line...and does nothing else). This was the bit of information I could have used from the beginning, that no one knows. All these places tell you to hold the power and volume up, and then let off power when the screen changes, but that never worked even once. You just hold the volume, and plug the USB from computer. This works.
For me it goes into a "FASTBOOT" header at the bottom of the screen that never changes.
I believe it does this because of my unsuccessful attempt to fastboot it before. And it does not have the right driver to get recognized in the computer. So I'm screwed as far as the recovery goes now.
It is rooted though. And it doesn't seem to have any alternate ROMS available anyways. so we're dealing with the loss of the recovery.
When I do try to use an app such as TWRP manager or CWM (ROM) Manager to reboot into recovery, I get a "boot certification verification -1" error instead of the fastboot line at the bottom of the startup screen and it boots normally from there. So many people asked about this "boot certification verification -1" and NO answers are available anywhere online. So that's where it stands for this phone right now.
Anyone know what driver I should use to get the thing recognized in the computer? I have downloaded a zipped fastboot tools, and it won't get recognized inside the driver manager as "android" only as "unknown device" so I can't use that route....I'm thinking about doing a factory reset to try to erase the fastboot attempt. That may not help though. Anyone?

I dunno, I have the H340AR, with this phones happens the same that with the Samsung Galaxy Ace 3, there are, 3G versions, 4G versions, regional versions, etc.. GA3 have 7275R, 7275B, 7272L, 7272T, I dunno, maybe if we could get a device tree for a H340 and an H320 we could make some TWRP and CM compiling, but I just can't figure it out how to make a device tree or even where to begin..
I successfully rooted my H340AR with Kingroot, it works like a charm. I haven't tried fastboot and I tried to install TWRP in this link https://dl.twrp.me/c50/ but I get that F error "Secure booting error". I guess I have my bootloader locked, so I'm trying to figure out how to unlock my bootloader.
I'm trying to contact with some developers and see if anyone can help me build a device tree.

Hi, I have that same phone H340AR LTE. I rooted it with Kingroot and also tried to use TWRP to gen into recovery and got that Security error. I only pulled out the baterry and turn it on again so it booted normally. I made a factory reset because I read that it could be a problem of OTA firmware update. Then I installed TWRP and BusyBox again and tried to get into recovery from TWRP option. When I did that, it showed up the Android lying in his back with a red triangle. I pulled a out the battery again and yes, it seems very dumb and simple but it worked and could reboot the phone.
However, I can't get into recovery from TWRP yet. I read that the problem with us not being able to unlock the bootloader(we don't have the OEM option) is because Leon has Lollipop 5.0.1 and OEM is for 5.1.1

lg leon h345 lollipop 5.1.1
This device has a locked bootloader. If you flash a custom recovery on it, it will not boot into recovery, but will report a security issue. You will lose all recovery functionality, including factory reset, adb, fastboot. If your phone fails to boot, you have a brick.

Recovery from bootloop (and other issues)

Ok, so... this is gonna be quite long to tell, but I need to explain the situation as carefully as possible because the problem I have seems to be very specific and potentially solutionless.
So, a week ago my Samung Galaxy Tab S6 Lite (SM-P610, CSC: ITV, which is the Italian Country Code and it's for unbranded devices, since my model is Wi-Fi only), suddenly started to restart itself and it's been stuck for days in a bootloop (i.e. it's stuck on the logo and if I hard restart it with Volume Down + Power, it gets stuck there again). Yesterday I found out that it's most likely a software problem, so re-installing the Android version should fix everything up... right? Well, I did just that but the device is still stuck on the bootloop.
Here I want to be more detailed: firstly, I'm 100% positive that the problem I have is NOT due to a virus, as I've never done ANYTHING that could potentially lead me to taking a virus (such as downloading apps outisde Google Play, visiting risky sites etc.); secondly, I followed a procedure that was supposed to repair my device without losing data. That's because I've stupidly never made a backup and I can't afford to make a factory reset. The procedure I followed consisted in finding the Android update I needed with Frija, and then downloading everything in the tablet with Odin. Also, I'm 100% positive that I made NO mistakes during the installation procedure. The only step that I did differently is HOW I installed the update: I did it with Download Mode, not with fastboot, because when I go into Recovery Mode and reboot the device into bootloader, the PC doesn't recognize my Tab, even if the PC does recognize that it's connected, as it makes the typical sound of when you plug something in a USB port (I have the USB drivers installed in my PC, I think it doesn't work because I never unlocked bootloader). What I get when I reboot into bootloader is "entering fastboot..." stuck screen and the PC and Odin aren't able to recognize it.
My questions are therefore these:
Is there a way to make a backup of the data of my device if I can't boot it (maybe via Download Mode)?
Is there a way to make fastboot work if I can't boot my device?
Is there some other way to repair my tablet that I can try?
Thank you for any help, this is my last hope to find a solution for my problem.

When your device is stuck on an Android boot loop issue then you can fix it by simply doing a soft reset. Turn off your device and the problem will be resolved.
Here are the steps to follow:
First, switch off your device and take out your battery from the phone.
If your battery is non-removable then turn off the phone for 3 to 5 minutes and again turn it on.
This method works effectively to fix the error of the boot loop issue. But if a soft reset does not work for you to fix Android phones stuck in the boot loop issue then you should follow the next method.
Method 3: Reboot System in Recovery Mode​Rebooting a phone in the Recovery Mode is known for fixing several errors and issues on your Android phone. So, if you are unable to start your phone in normal mode or your Android is stuck in a reboot loop, then restart your phone in Recovery Mode.
Method 4: Remove and Reinsert SD Card​You may also try to remove the SD card to fix the boot loop in Android. According to several user reports, this trick worked for them. So, you should try this.
First, turn off your phone > remove the SD card > turn on your phone normally, and check if your phone is out from the boot loop or not.
If it is still stuck in the boot loop, then go for the other solution.
Method 5: Reboot the Phone in Safe Mode​This problem may also occur due to problematic 3rd party apps. If you have recently installed an app on your phone and then you started facing this issue, then remove it from your device.
Or, if you are not sure which app is responsible, then try rebooting your phone in safe mode. Doing this will disable all the third-party apps on your Android phone and then you can easily find out if this is the reason behind this issue or not.
To do this, you need to follow these steps:
Start rebooting your phone.
When the device logo appears on the screen, long-press the volume-down button at the same time.
Now, your phone will automatically switch to Safe mode.
If your phone is no more getting into the boot loop, then it means one of the third-party apps installed on the device was causing this issue.
Now, find out the problematic app and uninstall it to fix the Android boot loop without losing data.
Method 6: Use Custom Recovery Mode​When you find your Android is stuck on the startup screen due to the boot loop issue, then you must try to restart the phone in the Custom Recovery mode. Here is the guide to do so:
To enter into the Custom Recovery mode press the Power + Volume down buttons simultaneously.
Select the “Advanced” option in the Custom Recovery menu.
Next, choose “Wipe Dalvik Cache”. Choose “Yes” when prompted for confirmation.
Move to the “Mounts and Storage” option and choose “format/cache”. It will clear the cache files completely.
Restart your device.
Method 7: Fix Android Bootloop Error Via CWM Recovery [For Rooted Phone]​Maybe you are not aware of this method but it’s a useful way to fix the boot loop issue on Android after the update. Remember that this method is only for rooted phones. Here CWM means ClockworkMod and if your phone is stuck on the Android boot loop then it must be downloaded and installed on phone. Read me

Thanks for replying but I already tried every method listed here.
At this point it sounds like you need to bring it in to a local repair shop & see if they have a fix.
The solution is to wait on the turned on screen until the battery dies completely. Then put it to charge and after a bit using the reset combo (pwr+volume down) once the circular battery charging indicator with the green border comes. (It's a matter of luck, this keeps happening to my tablet and even the official samsung store can't fix it even though they took money to do the same)

Samsung A52s 5G stuck in reboot-freeze loop

Hi, I have a Samsung Galaxy A52s 5G that goes into the following loop for two days:
boots up, waits for me to unlock the phone through the draw pattern, I unlock the phone, "Phone Starting" pops up, phone starts, I am able to navigate the phone and phone apps for something like 20 seconds and then it freezes.
Model Number: SM-A528B/DS
The firmware shown in recovery mode is the following: A528BXXS1CVI6
Why I am trying all this
This is my wife's phone. I thought she was backing up photos through google photos and she told me that she was doing it. Unfortunately, she was only uploading them on the local app and the backup was not working since her storage was full for several months. So, if there is a way to access her stuff from any Operating System please let me know. The problem, I think, is that I can't without unlocking the phone (of course).
Note
If I don't unlock the phone, the phone does not freeze but of course, I cannot do anything. Therefore, I suspect it is some thread that starts by default as soon as the phone is unlocked.
What I tried
I tried the following things:
Remove the SD/SIM card tray (just because it was easy)
I tried to boot my phone in Safe mode. I correctly entered in safe mode, the third-party apps were disabled but then the phone froze again.
I connected the phone to a laptop (running Ubuntu 22.04) and entered in recovery mode. Once in recovery mode, I tried basically all the options without any luck so far:
Reboot system now
Reboot to bootloader
Apply update from ADB:
I tried to download a firmware for my phone and then send it through ADB with the following command
`$ ./adb sideload ~/Downloads/A525FXXS4CVK4_A525FOXM4CVJB_HUI.zip`
and I got stuck at
`serving: '/PATH_TO/Downloads/A525FXXS4CVK4_A525FOXM4CVJB_HUI.zip' (~0%)" `
I don't know why
I did not try "Apply update from SD Card" yet
I did not try "Wipe data/factory reset" yet
I tried "Mount /system" but it got me the following error:"Error updating for slotselect"
I tried "Repair apps"
I tried "Run Graphics test"
I tried "Run Locale test"
I tried and then did "./adb reboot recovery" to test that I was able to reboot through adb and it did reboot the phone indeed.
Let me know if you have any ideas on what to try next.
Having a similar issue right here, please notify me what you did afterwards and if you managed to solve it
I am in the same situation and same try outs. Only one slight different. Phone does not start at all. Only "SAMSUNG" and "powered by android" logos. Then starts to bootloop again.
Did you find a solution?
@minidiable did you try to flash with Odin? You should have a try using CSC that avoid erasing data.
In any case, I'm coming back here to give my result after several try-outs and finally going to a Samsung Center.
My phone, entering in recovery mode, had from the begining a message at the bottom saying " E:[libfs_mgr]Error updating for slotselect ".
At Samsung Service Center they told me that this error may probably warn about motherboard failure. And after tearing down the phone and checked it, they changed the moterhboard. Sadly, All data lost. That's all.
