Hello,
I am from the i9300 forum. My GF has a SGH-i747. When she updated it to official Jelly bean using Kies, all seemed to go well but then when she booted up to her home screen the phone would reboot. It would continuously do this over and over again.
So we had to use KIES to do a complete format of the phone and reboot it. This deleted everything and made it factory brand new again. This is that option where you have to type in your serial number into kies to do the emergency firmware recovery.
Well a few months went by and today while my GF was using her phone it froze and rebooted. It is now stuck in the bootloop. I don't understand why this is happening. She doesn't have the phone rooted nor has she flashed anything on it. I'm not familiar with the SGH-i747 so I'm not sure if this is a common bug that has been addressed for fixed.
Please help, my GF needs her phone for work and she's a few miles away from me. Any help or advice would be appreciated.

Might've to get in recovery (hold vol up+home+power), clear cache, reboot.
If that doesn't work, back in recovery and factory reset, then reboot.

Yeah, I tried all that. I managed to back up her data so maybe we can restore her apps and information later. But this is similar to last time. I had her factory reset it, wipe cache, wipe dalvick, format system and format data.
We then followed by restoring her backup but the problem still persist. I might need to flash the stock ROM.
Could Fix Permissions fix the problem? It seems that the phone boots up to the home screen. While loading files, something at this point is causing it to bootloop. It will freeze after a few seconds and then reboot and repeat the problem.
Something is definitely conflicting within the first 30 seconds of booting up to the home screen. Any ideas?

Debloated stock ROM might be a good idea. When restoring, you might be bringing the problem right back. It should be very minimal (the needed stuff that you can't simply re-download or re-setup) to avoid issues coming back.

I edited my post above about fixing permissions.
But this is very similar to what happen last time. I had wiped factory reset, wipe cache, wipe dalvick, format data and system, installed fresh new ROM and that boot looped too.
It took KIES emergency firmware recovery (where you have to type in your serial number) to fix the problem, but everything was deleted even the internal SD card.

I doubt fixing permissions will change much but could try it.
From the way you describe it, it sounds like a app or some bad data. Is she using a external SD? If so, try booting without it. If not, my guess is that there's a rogue app or something corrupted her data.

Thanks. Yes she's using an external SD card. I will have to get a hold of her phone and see what's going on. The first time it happened was because we upgraded to Jellybean. it happened right after so I don't think it was a rogue app. This time she just pulled her phone out of her purse and noticed it boot looping. Something sounds wrong with her phone... I think we might need to send it back for warranty repair.
Okay I need help. I have discovered the problem and it is the SUPERUSER app. When Superuser was updated it caused my GFs phone a boot loop.
Now that I put fresh rom and cleared everything her phone was working. But the moment I rooted the phone itboddly didn't come with SU, so upon installing SU nothing could access SU for some odd reason. So I found out you need a SU for Jelly Bean, upon installing this version of SU is when everything went to he'll and the same boot loop came back.

What rooting method did you use to root your girlfriend's phone?
If I'm not wrong, most of the rooting method -- if not all -- for the SGH-i747 involve the SuperSU app instead of the Superuser app. And I believe most of the custom ROM, if you switched ROM, come with SuperSU pre-installed. If you try to install Superuser (without removing SuperSU), might that be the cause of your trouble?

Perhaps, I will try and fix the problem again. We just got back from a movie. Thank you.
if everything doesn't work
here's what you should do
first go look for AT&T 4.1.1 stock rom
download ODIN
go to recovery by vol up + power + home
clear cache, data and dalvik
flash stock rom thru odin.
that should fix soft brick
I flashed MOAR 2.3 and update. I was playing around with my phone and decided to encrypt my device. I was having problems and I shut off my phone since it wasnt responding. Upon rebooting, I was prompted to factory reset since encryption failed. I did so, and it gave me the same problem... Here is what I've tried thus far
-wipe cache and dalvik
-factory reset
-restore previous backup (failed)
-odin to stock and factory reset
-reflash zip
-still failed
I am able to access download and recovery. but can't get past annoying prompt. Any ideas. Just an FYI I have Sprint Total Equipment Protection and was wondering if I can claim this as lost or i can destroy it beyond repair so I can get a replacement without them checking if it was rooted.
THANK YOU
Ok first, go into recovery and make a backup as is. Then download your rom again, or reflash if you have it, and flash with a full wipe (system, factory reset (aka data), cache, and dalvik)
Now try to see if it boots up. If it does, you can go into recovery and advanced restore your data.
There was someone else on here who had gotten stuck with encryption when trying to flash something. His thread might be a good place to start... I don't have the link with me, but search q&a for encryption or encrypted.
If I recall correctly, he had to Odin back to stock recovery. I could be wrong, though, it was a little while ago, and I was just reading through the thread, not actively participating in it.
Hope you can get your phone fixed!

Phone was rooted and running CM10.2 nightlies just fine. I had to encrypt my phone for work email, no issues. I now want to change ROM's to a TW because of WiFi Calling.
So here is what I did:
- I did a TWRP (2.6.3.1) backup before starting
- Advanced Wipe Dalvik/Cache/System/Data/Internal Storage as well as Format Data to remove encryption
- Downloaded SWARMROM, flashed ROM, Modem, SuperSU.
Flash went good, rebooted with T-Mo splash and boot animation. Before I can do anything, I get a prompt to "Enter your PIN or password to use the encrypted device memory". My old password doesn't work and it won't let me in. All I can access is Emergency Call.
I have even formatted my external drive thinking it might be what is still encrypted, re-ran the install process, but same result.
I did trip the KNOX counter somehow, if that matters.
Any advice?
Go back into recovery and restore your backup, reboot and remove encryption, use titanium backup for app data

The backup doesn't have encryption. But there is somewhere on the phone that a Stock ROM is detecting encryption from. I can go to any Cyanogenmod 10.2 ROM, but not a Stock or even OMNI.
Finally got it.
ODIN root66 Stock ROM, reboot to encrypted error. Boot into factory recovery and wipe/factory reset, then wiped cache for good measure. Rebooted and it came up without the encryption prompt. Let the WiFi Calling commence.

You saved my arse today, THANK YOU! I have been out of the flashing game for some time now so I was getting stuck when I had the same issue as you, but thankfully, now it's back to normal, phew!
I need to get Data from my Samsung Galaxy S3 SGH-1747 and it won't boot past the Samsung Logo.
Someone told me to...
"Get TWRP image for your S3 model, flash image using Odin, boot into TWRP recovery, mount storage to PC and recover data."
I'm very new and sorry lol. Could someone help me with the steps necessary? I have no idea what TWRP is. My phone is not rooted. Is there a guide with photos or a video? What do I need to download for Odin? How do I flash?
My phone is in the most recent Android for it.

I went to the post and it said I need to download to my phone from play store.
How?
My phone is not rooted and is stuck in Bootloop.
Please and thank you if you could help.
Before you do anything, try to figure out if you can boot your phone into these 2 mode:
Download mode - With the device powered off, hold Home + Volume Down + Power
Recovery mode - With the device powered off, hold Home + Volume Up + Power. (Take a picture of your recovery mode because it will tell your bootloader version)
If you can't get into those mode, your phone is likely to have a bigger problem.

The instruction is for Samsung i9305 but it will work on d2att. To flash TWRP into your phone, you need to follow this instruction. (https://wiki.lineageos.org/devices/i9305/install). Also you need those files:
Heimdall suite - http://glassechidna.com.au/heimdall/#downloads
TWRP image - https://twrp.me/Devices/Samsung

The only way to flash stock firmware into the phone, is with the software Odin. It's basically starting your phone with a fresh firmware through 'Download Mode' with your phone (With the device powered off, hold Home + Volume Down + Power). It will erase everything.

There was a link in the thread to the official TWRP website with instructions for using Odin to install TWRP for the d2att which is the SGH-i747: : https://twrp.me/samsung/samsunggalaxys3att.html
Download the tar version of TWRP from here: https://twrp.me/Devices/ I recommend starting with version 2.8.7.0 as a starting point.
Download Odin 3.07 from here: https://www.google.com/url?sa=t&rct...ntid=1168421&usg=AOvVaw0aq_x8M8nbsqDFAFe9tFoy
Download and install the Windows Samsung USB drivers: https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows. I assume you are using a Windows computer.
Make sure the battery is fully charged. Open Odin, do not check anything except f reset time, click on the PDA box and select the TWRP tar file, connect the phone in download mode to the computer with the original Samsung USB cable, flash the TWRP. When you see the word reset, remove the USB cable from the phone, remove the battery, replace the battery, use the button combination to get into recovery. Once in recovery, mount the data partition and copy of the data.
WARNING: flashing a phone always involves risk and you could wind up with a bricked phone and/or loss of data. Proceed cautiously and at your own peril.
Thank You
Thank You So Much!
One love, Much Love ??????

Yes it will, you need to figure out what's making your system bootloop and resolve it or wipe data and cache.

Any idea how to investigate?
How do I wipe data and cache on TWRP?
Would backing up Data but not system, help restore files like the memos, text messages etc?
Because I could backup the Data and then wipe factory reset and then reinstall the data backup.
How do you factory reset from TWRP?

The data is what makes the system bootloop in most of the cases and since you're not rooted it is certainly the data what's causing the problem so restoring it would solve nothing.
The option is there on twrp to wipe data and cache.
---------- Post added at 05:41 AM ---------- Previous post was at 05:39 AM ----------
To inevstigate hmmm
You need to remember what you did before the bootloop happened
For example if you installed and app try to remove it and it's data using the twrp file browser.

I think you can try to remove Google Photos apps via adb and see if it does fix your bootloop issue. Since you have a backup, you can undo your steps. https://forum.xda-developers.com/showthread.php?t=559925.

Before proceeding, I recommend copying what you can to a computer by mounting the data partition. Then, I would create a complete backup (system and data). Once completed, copy the back to at least one safe place, preferably 2.
Now, try wiping the cache only and reboot. It may be a cache problem that is preventing the phone from fully booting.
Unfortunately, I'm not able to provide instructions to back up text and notes.

I wiped cache and still nothing.
Is there any other options besides factory reset?
Can the backup bring it back to the way it was or will it make it bootloop again?
I haven't used twrp for a long time but you could try restoring the backup and wipe the cache before booting.
Note that restoring your backup will overwrite what's currently in the phone storage.

The only option maybe you have is using adb to uninstall apps one by one and hope it fixes the bootloop. You can try maybe to clear the dalvik cache + cache but I think you have done that.
I have been in this situation before. It's not fun at all. The only way to backup/recover data in a modular way, is with apps like Titanium Backup [root] and Helium. Backup your app + data when the phone is working. When you have a bootloop, do a factory reset and restore the app data incrementally. They are really great apps.

Hi,
My moto one Action with stock firmware is stack at the Android One boot screen.
Is there a way to reset the system without loosing apps and data?
The recovery mode is not having the option to wipe the cache…
Flashing firmwares usually don't wipe data, unless it was triggered by a file, or an option. I doubt it'll be of help even if you have TWRP installed, cause the data partition may be encrypted.
If you have bootloader unlocked, you can use TWRP to take a backup of your files/apps.
