My wife's SG3 SGH-I747 will show the white "Samsung" logo, then the white Samsung Galaxy S3 logo, then it goes black. Pulled the battery several times, no luck. I'm assuming this was caused by a failed update.
I can get it into download mode, I have cleared the Cache and rebooted with no luck.
I'm not a complete rookie at this, but I haven't done it for years and I'm afraid of losing the data on the phone.
How would you suggest I proceed to save the data? (Pictures and movies)
install a previous stock rom via the download mode? Or odin? I don't have a custom recovery installed.
Will the unbrick method work in my situation? If so will it wipe the phone?
I've searched the forum and can't find anyone saying if the data is salvageable.
I know it's my fault for not backing up her data, but she's in tears over losing pictures of the kids. Please help if you can.
Thanks,
Installing a ROM via Odin may require you to do a factory reset before it boots.
Boot into download mode and look at the screen. Do you see anything about a warranty bit?
I just get the download screen. (See attached picture) Nothing about a warranty
Options are:
Reboot system now
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
Then it shows:
#MANUAL MODE#
--APPLLYING MULTI-CSC...
APPLIED THE CSC-CODE : ATT
SUCCESSFULLY APPLIED MULTI-csc.
.
That is the recovery mode, not download mode. To get into download, press the home button, volume down, and power button. Once the phone starts to boot, release the power button and hold the other two until you see the download message and press volume up to continue.
You were right. In download mode it says:
ODIN MODE
product name: sgh-i747
CURRENT BINARY: CUSTOM
SYSTEM STATUS: CUSTOM
QUALCOMM SECUREBOOT: ENABLE
WARRANTY BIT: 1
BOOTLOADER AP SWREV: 3
DOWNLOADING....
DO NOT TURN OFF TARGET!!
Since the warranty bit is 1, this tells me you have at least a 4.3 bootloader on your phone.
The only thing I can think of to get the files would be to flash twrp onto your phone in download mode. Then mount the drive, connect the phone to your computer, and use Windows Explorer (assuming you're on a Win machine) to copy the files off the phone.

Flashing a new rom would wipe the phone?
The last full firmware AT&T released was 4.1.1. The AT&T 4.3 and 4.4.2 ROMs were only released as OTA updates for an existing stock ROM and stock recovery on a phone.
If you want to flash a 4.3 or 4.4.2 ROM, you need to use a version found on XDA to to this. Trying to flash a 4.3 ROM onto a 4.4.2 bootloader and modem could brick your phone. In fact, any flashing procedure can result in a brick or a loss of user data.
Even if you successfully flash a ROM, the ROM may not boot without wiping the cache and all user data first.
Good to know, Thanks a BUNCH for the help.
You are awesome!
Now...let's pray this works!
If you install a custom recovery, you can create a backup of the existing ROM even if the ROM doesn't boot.
Cool,
Odin 3.07 sees the phone, i downloaded openrecovery-twrp-2.6.3.0-d2att.tar. Is it is loaded through the pda option?
Thanks again for your help.
Yes, flash it via the PDA section. Do not check anything except F.Reset time.
Flash TWRP, when you see the word Reset in the status windows, remove the USB cable, remove the battery, replace the battery, boot into recovery, create a backup of the rom, preferably to an external SD card. When the backup is complete, attach phone to computer, mount the partitions, locate files on the phone you want to save.
Done with install, backing up to SD now.
Ok, TWRP worked, I was able to safe the files (THANK YOU!!!). I used the file manager to find and copy the files to the sd card, then did a full backup. It never did mount to the computer, even after the drivers were installed.
It saved the backup with the file name: 1970-01-01--00-18-57 KOT49H.I747UCUFNJ1 so I'm guessing that is the build number it was trying to update to (KOT49H.I747UCUFNJ1). I can get to recovery mode and download mode, how should I go about making this phone work again?
I'm not sure how to check what version of bootloader I have. You scared me about the "bricking it" warning about flashing the wrong rom with the wrong bootloader.
If your are sure you saved the necessary files in two different places, boot into recovery and wipe cache , dalvik, and reboot. If it still won't boot, wipe cache, dalvik, and data in recovery, reboot.
Another option may be to use adb to pull files from the phone, you can even pull entire directories. I will work from recovery mode. There are tutorials on installing the toolkit for adb w/o installing all of the platform development tools. I use Linux so I can not verify how to do this on Windows, but it looks as simple as it was for me. Once adb is present on the PC, boot the phone into recovery, and in a command prompt window enter the command
Code:
adb shell pull /path/to/picture/directory C:\path\to where\you\want\it
and example may be
Code:
adb shell pull /sdcard/DCIM/camera C:\recoveredphotos
Check that I did my Windows path correctly
Hello everyone. I have a tmoble s3 that was once rooted and then updated with kies and ran on stock firmware. The phone was updated to the latest firmware but I had lost root. I left it alone and all was well for many months. The other day after charging the phone it was unable to complete the boot. I can boot to recovery and to download mode but it wont safe boot or normal boot it hangs up at the last phase. I took the phone in to a samsung rep and he tried to load the firmware on the phone he did a home recovery but the phone still doesnt complete the boot. I had already tried factory reset before taking it in and it failed. I am not sure how to fix it since it isnt rooted any ideas on how to fix the phone? Is it possilbe to fix this phone or is it just a paperwieght now? Can you odin a pre rooted rom on a phone that isnt rooted and wont boot in order to enable usb debugging or developer options? I have no idea how to proceed so any advice would be appreciated. Thanks in advance
To quickly check the phone's functionality, I suggest the following:
1) download Odin 3.07 from here: https://www.google.ca/url?sa=t&rct=j...07763241,d.dmo
2) download the tar version of TWRP 2.8.6.0 from here: https://dl.twrp.me/d2tmo/
3) download the latest cm12.1 for the phone from here ( http://www.cmxlog.com/12.1/d2tmo/) and save it to a micro SD card;
4) download the version of cm12.1 gapps you want from here (https://wiki.cyanogenmod.org/w/Google_Apps) and save it to the same sd card where you saved CM12.1;
5) place the micro SD card into the phone;
6) boot the phone into download mode;
7) open Odin 3.07 and uncheck everything except f. reset time;
8) click on PDA and browse to the tar TWRP file and select it;
9) connect the phone and it should show up as a com port in Odin;
10) flash TWRP;
11) when you see the word RESET in the status window, remove the USB cable, remove the battery, replace the battery, use the button combination to get into recovery which should now be TWRP;
12) perform a full wipe of system, data, and cache;
13) flash CM12.1 and gapps from the micro SD card;
14) reboot and enjoy
ive had help in rom section but unable to get the rom installed trying to install the ultimate note 5 rom ok i follow op instructions tried muti twrp and the lastest philz ever time i flash the rom i get a error 7 code tried muti formatted sd cards tried putting on phone storage then flashing still same error.. ive read on the error 7 a little bit about it look in the updater script dont see the line it says to erase,ive flash other rom no problem but this 1 keeps failing with that error the picture says twrp 2.8.6 did it just to try out but im on twrp 3.0 now when i got the phone it was already on 5.1.1 ok1
I will be as specific and give as much detail as i can here...
You need to start over with a clean slate. Use standard class 10 micro-sd card and don't mess with multi format whatever. Use TWRP 2.8.7 or 3.0.0. Start by rebooting into recovery and wiping everything clean several times. backup any files that you need to keep. But you must wipe internal sd, system, cache, data and dalvic-cache. wipe thenm in advanced wipe options of twrp. Next reboot to download mode. Launch odin 3.10.6 or newer on your pc. connect your phone to your pc via the usb cable. In the options tab of odin make sure auto-reboot and reset time is CHECKED!!! Open the official stock OK1 rom tar using the AP button in odin. Once the md5 check completes just press start to flash the stock rom. when it finishe LET THE PHONE REBOOT!!! Once the phone boots, setup as usual then go into Settings and open "Activate this device". Let it do it's thing and it will automatically reboot. Once the phone reboots, go to settings/System update and do the prl AND profile updates. Reboot your phone again. Then make sure your data and calls work as they should.
Once you are on stock and have done all of these steps above you are ready to odin TWRP. Download the tar version of TWRP to use in odin. It is the best way to flash recoveries. Launch odin on your pc and use the AP button to add the TWRP tar. In the options tab you can uncheck auto reboot if you want. (I've never had to do that but you can). Once it flashes you can let the phone reboot or you can just pull the battery then force reboot into recovery by holding the volume-up, home and power buttons until you feel the phone vibrate. Release all buttons and wait for TWRP to boot. Once in TWRP, do all of the wipes same as before multiple times. Then for good measure go to TWRP homescreen and press "Reboot" then "Recovery" and this will reboot recovery and ensure that the rom zip will flash with no trouble. Reboot recovery then flash the UN5 rom and remember to wait for data to conect before proceeding with setup wizard. Success. If this doesn't work then give up and leave your phone stock until you figure out what's causing your problems. Good luck.
The post below started out as my proposed plan for updating a S3 i747m (Canadian) from stock 4.4.2 to CM11. I've since gone back and updated it with the results to turn it into more of a guide for the next moder. This will not do a carrier unlock and it will flip your warranty bit.
Prep:
Download and install Odin_v3.09.zip (recommended for JellyBean/KitKat firmwares) (droidviews.com/download-odin-tool-for-samsung-galaxy-devices-all-versions/)
Download and install the Samsung drivers (samsung.com/us/support/owners/product/SGH-I747MBBATT#)
Download the latest appropriate TWRP (at the time if writing it was twrp-3.0.2-0-d2can.img.tar, not the .img but the .tar file, from the dl.twrp.me/d2can page).
Download CyanogenMod and copy it to the external SD card (started with the latest CM11 build with the stagefright fix from download.cyanogenmod.org/?type=snapshot&device=d2lte).
Download Gapps and copy it to the external SD card (personally I grabbed the ARM/4.4/Nano from opengapps.org).
Install recovery:
Boot into Download Mode on the S3 (hold home + volume down, hit power button, then volume up at the confirmation screen)
Launch Odin (as admin) and uncheck everything except Auto Reboot and F. Reset Time.
Select the TWRP .tar file in the AP (apparently used to be PDA) mode and flash the recovery
Once the phone has rebooted successfully, shut it down.
Install CyanogenMod:
Boot into recovery (hold home + volume up, hit power button)
Do a nandroid backup for good measure
Do an advanced wipe of your system, data, internal storage and caches (if you don't you get an error 7)
Flash CyanogenMod
Flash Gapps
Reboot
That successfully installed CM11. As it went so smoothly, I decided to try install CM12.1 right away. I grabbed the "cm-12.1-20160314-NIGHTLY-d2att.zip" (from here: forum.xda-developers.com/showpost.php?p=66726324&postcount=1202), got a copy of the ARM/5.1/Nano from opengapps.org and repeated the above process with success. All seems to be stable so far.
One unknown I had was the deleting of "/system/etc/install-recovery.sh" and "/system/recovery-from-boot.p" as specified in some guides. audit13 mentioned it probably wasn't necessary and I can confirm it wasn't.
Thanks again to audit13 for their vote of confidence.
Plan looks good except I don't think it is necessary to mount the partition in twrp and delete the two files. I have flashed the Telus and T-Mobile versions of the s3 with custom roms and have never had to delete any particular files prior to flashing.
This is only my second time rooting a device, and it's been a couple years so I forget how I achieved it last time. I want to root my Galaxy S3 (SPH-L710) so I can put a custom ROM on it. However, I'm a mac user so most of the rooting instructions I've found don't work, and since I'm such a n00b the guides all seem to require knowledge I don't have. I installed Heimdall on my computer, but I could only get the CLI and not the GUI.
Here's the basic idea I think I need:
- boot in download mode, use Heimdall to transfer some files (which?) to my phone
- pull battery to get phone to shut down
- reboot in recovery mode, and hopefully the options will have changed from stock options to include "wipe dalvik cache"
What files will I need to transfer to my phone? I grabbed some AICP files but they're not named the same way as the example in the Heimdall README. Will rebooting in recovery mode really give me the option to wipe dalvik cache? What do I really need to do to root my phone?
After lots of trial and error, I think I figured it out. In case someone else is similarly stumped, I:
- used Android file transfer to move a zip file of a ROM to my phone (I used an unofficial AICP link I found here)
- powered down my phone
- booted my phone in download mode
- used Heimdall to transfer files to my phone using the command
Code:
sudo heimdall flash --RECOVERY recovery.img --no-reboot
Where recovery.img is a file I unzipped from the appropriate TWRP file.
- while the phone was still on and in download mode, held down the power, home, and volume up buttons (don't know if this step is necessary) and the phone powered down
- rebooted the phone in recovery mode
- then, I had a TWRP screen from which I could:
- wipe the dalvik cache
- perform a factory reset
- install from the zip file I had previously added to my phone
-reboot
