How did I successfully recovered my soft bricked Samsung Android phone - Android

I am writing this post with the only intention that someone will find it useful and will not need to spend hours/days in troubleshooting. Although, my Samsung phone model and cause of soft-bricking could be different, the process to recover should remain unchanged to other Samsung Android phones to large extent. This process do not need to route your phone. It is just process of flashing your phone with stock ROM (official ROM). To my surprise, Samsung service center too didn't do all this for me (when they were expected to do this) but they simply told me that the phone need to be factory reset losing all its data. However since my data was very important I thought to give try on my own. And then I spend many days in figuring this out. Here I am sharing details:
1. My phone was soft bricked while upgrading from Android 9 to Android 10. It was stuck at the SAMSUNG logo after booting.
2. Phone was having FRP LOCK & OEM LOCK both turned on (We can this info from restarting phone in recovery mode by pressing Power & Volume Up buttons)
- From info available on internet, I realised that if phone is FRP LOCK or OEM LOCK, then flashing it with TWRP is NOT recommended.
- So I decided to flash it with stock firmware only (A Stock ROM/Firmware is an official software that is designed by the manufacturer for a particular device)
3. To flash firmware using Odin, we first need to turn on the phone in download mode. Generally we can do this by starting phone by pressing Volume down + Power buttons
However, for some reasons my phone was not going in download mode (even after pressing those eyes). But it was going in recovery mode.
4. I used USB Jig to put the phone forcefully in download mode. (USB Jig is available on Amazon)
- Turned off phone using option provided in recovery mode
- Attach USB Jig
- Then press power button. Phone starts in download mode. Remove Jig quickly and attach USB cable and connect it to computer to flash it with Odin
5. Then I used Odin to flash stock firmware. In download mode, Odin detects the phone.
- In my case the phone was soft bricked because of the Android 10 upgrade. Hence I flashed it with Android9 firmware.
- Android9 stock firmware available here: https://www.sammobile.com/samsung/g...e/SM-A605G/INS/download/A605GDXU6BSL1/310956/
- Important: Read all instructions carefully on the site above how to use Odin to flash. Especially remember: Use HOME_CSC_*** if you want to keep your apps and data. This is VERY important.
- Also, first add all those AP, BL, CP etc files to Odin & then connect phone (which is in download mode) via USB and then click on Start button in Odin to start flashing
- After flashing with Android 9 firmware, I disconnected the phone from PC and restarted. But it was still hanging at Samsung logo. It was frustrating.
- But then I again rebooted the phone and this time just connected to PC, then it took some time to get the Samsung logo but then whoaaaa... it started successfully I was able to see all the data

Download Odin. http://www.android.gs/download-odin-3-07/
Find the original firmware for your device and download to your PC. (I can't help you with this)
Turn your phone off.
Boot into download mode on your phone (volume down + power button; hold for about 3 seconds whilst it boots).
Plug your phone into your PC via USB. Wait for the ID:COM message to show in Odin.
Follow the instructions here to flash the firmware onto your device: http://forum.xda-developers.com/galaxy-s3/help/guide-odin-flash-guide-t1671969
Reboot.
You WILL lose any data you have that isn't on an external SD card. That is the only data which will be safe.

[Q] Did I brick my phone?

Hello xda, first post n00b here,
I recently got my hands on a SIII (lot better then my old htc one V), and I wanted to install cyanogenmod on it. So I installed the i9300 recovery rom on it and for a short while it seemed to work, but when I tryed to sideload cyanogenmod something went wrong. Everytime I rebooted I got thrown into the downloading, do not power off target!!-screen.
I quickly found my mistake, I did not have an i9300 I had an i9305. With some help from the lovely people at #cyanogenmod (shout out to you PsychoI3ob) I figured out I had to flash the stock rom. I could not figure out how to do this with heimdall, so I downloaded Odin. With Odin, everything went right untill it was somewhere around 99%. The write failed. Now the only thing I see when I but the batteries in my phone is: Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.
So now I would like to know: Did my phone just become a paperweight or is there still anything I can do?
Thanks a lot for reading trough!
If you can get back into download mode by shutting down your phone, and then boot while holding the volume down, home button and power button simultaneously you could try reflashing stock ROM through Odin.
If the phone turns on as soon as you put the battery in then you will have to take the battery back out, and then whilst pressing Vol Down and Home button put the battery in (I've had the same issue on a Galaxy Ace II with the phone booting as soon as the battery was put in, but managed to get back into download mode and reflash by doing as I described)
If you manage to successfully reflash, boot into recovery (turn off, then hold Vol Up, Home and Power) and do a factory reset from there just for good measure.
Good luck :good:
"Firmware upgrade encountered an issue..." It is also download mode. You can use Odin to flash while this screen has been displayed or launch Kies and restore your original firmware by firmware initialization option from tools menu.
Write model name GT-I9305 and your phone serial number (under battery). Kies will check what version of firmware was originally pre-installed on that device. Will download and flash it automatically. After that you can upgrade to newest stock. Write custom recovery via Odin, flash custom rom from CWM.

Recovering data from brick I9300

Hi, I'm completely new on all this mobile/android stuff, also sorry my poor English.
Out of nothing my phone bricked and I just wanted to recover my files from the internal storage.
Why I've tried so far: to install a custom recovery using Odin. Installation process were OK, I guess, judging by Odin and phone messages (on phone download mode you can read "custom binary download: YES (3 counts)". That's 3 because I've tried twrp-2.8.6.1-i9300 (tar) twice and recovery-clockwork-touch-6.0.4.4-i9300 (tar) once.
Where I'm stuck: I cannot see the options to access these recoveries form the recovery mode, just the already existing options (reboot, apply update, ...).
Thanks you for any help!

First of all flash chainfire auto-root. You can download it from here: https://download.chainfire.eu/229/CF-Root/CF-Auto-Root/CF-Auto-Root-m0-m0xx-gti9300.zip
Then try again to flash TWRP. If it will go ok, you can copy from recovery data from internal storage to sd card
Hi There,
I am in a similar predicament.
I have a Galaxy S3 (purchased in 2012) and a few weeks ago, the phone started to automatically switch off (when I locked it) and I would have to hold the power button for about 15-30 seconds for it to switch back on.
I checked the power button(to see if it was broken and pressing down all the time) but it seemed to be fine as whenever I pulled the battery, the phone would NOT come on unless I held the power button.
About 1 week ago when i tried to turn my phone on, with the power button, but it would get stuck on the samsung logo screen (it was frozen, not looping).
I was still able to enter both recovery and download mode. So I tried wiping the cache but it did nothing.
Then I tired flashing the ROM with ODIN and it passed but it also did nothing (tried flashing multiple times all with "PASS" as well as wiping the data cache in conjuction with the flashing but to no avail).
Tried flashing it again with BL and it also passed, but now whenever I try to enter Recovery Mode or Turn the phone ON it would display a White Scrambled Screen which probably means eMMC failure.
How do I retrieve the information on the phone ?
N.B;
- I do not care about fixing the phone, only want the information
-I cannot enter Recovery Mode, BUT I can enter download mode.
-When I connect S3 to PC it is detected (In Device Manager it states "Samsung Mobile USB CDC Composite Device")
-I did have my phone password protected before this happened using the Pattern Password (you have a 3x3 Dot grid in which you can use to draw a line(s) which will function as a password)
-My phone is an S3 GT-I9300
-Never interfered with the ROM or software on the phone before this (was running the official android software from Samsung which I believe was Android Version 4.3).
-I am not very versed with computer programming so please use simple words to help me
As previously stated. flash cf-autoroot and then flash twrp, both via odin. Then you should be able to access twrp (hold home and vol+/- (cant remember which, opposite from download mode) and press power once.
If you can get to twrp you can use its built in file manager to move your data to an sd card.
If no twrp its what is technically known as f*cked.
I wish I stole my HTC M9.

Short and sweet: TWRP is a popular recovery system; cf-autoroot is the preferred method for rooting some samsung devices by member Chainfire
I could lay out all that here again in detail, but it's safe to say you are better off in the long run if read up on that stuff by yourself...
Check the excellent threads I linked in my signature! Trust me, it's not as complicated as it seems.

Samsung S6 Edge: stuck in emergency recovery page

As title. My phone is stuck in the emergency recovery page: use the emergency recovery function in the smart switch PC software. I cannot turn the phone off, I cannot go into recovery, and I cannot go into download mode.
I attempted to root the device using kingo but it failed. It was my first time rooting a device. So my phone essentially got stuck when it restarted at the "Samsung S6 Edge: Powered by Android" black screen. I then managed to "recover" the device by using Odin and flashing a stock firmware.
So I got back into the device and tried to change the settings back to what they were before. I disabled USB debugging (Bootloader option is not available for my mode, SM-G925I).
Then...having the itchy hands I do, I checked out the security portion under settings, and I saw that there was "unauthorized changes made". The program suggested that I restart my phone so as to get rid of those changes..which I did. And since then, it has been stuck again.
I actually took a trip down to the service centre where the tech actually managed to turn the device off, and I was told that warranty was void. In any case, when I returned home I tried to flash the same stock firmware that I used earlier but ODIN failed. I redownloaded the stock firmware for 925I from a couple of places and they're all 1.5gb+; but every time I try to even load the firmware Odin just hangs and I have to end the task...
Right now, I'm attempting to use smart switch and the emergency recovery function but it has not worked the first time, at the second stage where installation actually takes place. While the phone was connected, window's kept giving the notification that the device was not recognized. I'm giving smart switch a second desperate try and this time round I'm receiving no notifications from windows (so I suppose that's a good thing..). But assuming that smartswitch does not work? What are my options considering:
1) Failed root using kingo root (one-click stuff..wish I had known better)
2) USB Debugging is not enabled
3) Unable to enter recovery mode
4) Unable to enter download mode (but a download bar appears when I attempt to use Odin at the emergency recovery page)
5) 5.1.1 android system
6) Phone is not recognized by smart switch (might be because it is in the emergency recovery mode)
Really at a loss here..I'm helpless with tech and I really should have just left well alone. Jailbreaking was so much easier...Samsung quoted me $200+ for the replacement of the motherboard of the phone, which I will probably take up if the situation is really beyond repair.
Thanks in advance..

Galaxy S3 GT-I9300 Failed to mount /efs

Hello a few days i restored my galaxy to factory settings from inside the own phone settings everything was working fine until a couple days ago the phone started to rebooting every now and then
Right now is stuck on the samsung logo after you turn it on and in the recovery menu i got this error
E: failed to mount /efs (invalid argument)
I try to wipe the cache date and even doing a wipe from the recovery menu but nothing when the phone turn on and gets to the samsung logo it stays there a while and reboots again
I try doing this instructions from this post from another forum
The key for me was selecting the second item in the Tools menu (Firmware Upgrade and Initialisation?) - it seemed to bypass that whole 'connecting' process and just went to work. Here's the writeup that I put together (I need to insert the Kies screenshots that I captured).
- if you don't already have the Kies software installed on your PC, download it (just search Google) and install it. The first time it runs it'll update itself to the latest version so make sure you run it once before proceeding.
- put your phone in Download mode: with the phone completely off, press and hold the Volume Down and Home and Power buttons simultaneously, and release them all when you see the Samsung splash screen
- connect the phone to your PC with the USB cable that came with the phone
-- if you've never had the phone connected to your Windows-based computer before, you'll see messages about installing drivers, etc - just wait until this is done (may take 5 or 10 minutes) [I don't know what happens if you have a Mac - it probably just works]
- in the Kies software, select the second item in the Tools menu and just follow the prompts to enter the model number (in CAPS) and IMEI/Serial Number (both found under the battery - it's ok to remove the battery at this point)
- the Kies software should start downloading the correct firmware for your phone from the Internet; once that's done (depending on your Internet connection speed) it'll begin downloading that to the phone (this probably takes 10 minutes or so)

Been honest i'm completely lost here
Can someone please give a valid link to download?
Edit: Sorry, wrong post.
You can try flashing a recovery (cwm official is best) via odin but most likely you'll need to flash a stock rom, definitely if the cwm flash doesn't solve it.
