[Q] Softbrick, bootloop, TWRP Password

My girlfriends S3 (Bell, I747M, d2can) is currently boot looping. It had a custom ROM on it, but I'll be damned if I could tell you which one. It was working, then it wasn't. No updates, no flash/wipe/etc.
Now I turn on her phone, and it gets to the ROM's boot screen, and just as it's about to complete, it restarts again. I can enter TWRP (2.6.3.1) but it requires a password (which is a bug, afaik). I can press "cancel" and try to reset/wipe, but it won't mount or reset the cache partition, so it fails.
I used Odin (3.07, 3.09) to try and flash TWRP 2.6.3.0 and 2.7.0.0, and both failed. The result was Odin would reboot the phone, then it would enter the same bootloop, and the recovery would still be TWRP 2.6.3.1.
I tried downloading a stock S3 firmware and flashing it with Odin. Same problem.
I've tried new drivers. New cable. New USB port. I've tried using a different computer. Always the same result.
So a summary of what I can/can't do:
Can't use TWRP to reset/wipe
Can't use ADB Sideload
Can't modify device via ADB
CAN see the device via ADB
CAN enter download mode
Any help?
I pulled DMESG at some point during all this. Maybe it can help shed some light: http://pastebin.com/4c2uL3Qq

Dont know how much help it is but I quit using TWRP because of that bug, now I use CWM the philz touch version and haven't seen that again. When you are flashing the rcovery with ODIN you must absolutely uncheck the box for auto reboot. when you get the message that says the flash was successful you should then unplug the USB cable and do a battery pull, reinsert the battery, press the volume up key and the home key, press the power button until it vibrates then release the power button only, once the phone boots into recovery you may release the volume up and home buttons.
If you are trying to flash Stock roms be darn sure you have the right stuff IE AT&T phone using 4.3 you find here on XDA the correct odin flashable tar or for any other use www.sammobile.com if you have a canadian I747M go to www.sammobile.com and find the right one for the bootloaders currently on the phone. If you flash a phone that has 4.3 bootloaders on it with older bootloaders you will have an instant Hard Brick. Use Extreme Caution with bootloaders and ODIN tars. you could also use custom recovery to flash some stock or custom roms too those are alot safer and less likely to hard brick.
I think you are on the right track to trying to fix your ahem her phone, a little patience and reading go a long way IIRC the recovery thread instructions outline the need to uncheck the auto reboot box, with that being said you aren't the first one to over look it I have done it myself a few months ago. I wish you the best of luck and hope that a cache wipe will fix what you have going on if not try a factory reset, Good Luck.

Appreciate all the help! I've tried pretty much every combination.

I assume that's where it's supposed to be. Then I enter recovery and it's still the same TWRP 2.6.3.1. Very strange.
I don't think her phone is using 4.3 bootloaders, as I don't remember them being available when I flashed this phone. I'm a Nexus guy, so maybe I'm doing something wrong this time.
EDIT: I also seem to recall on my phones that when I flashed something in Download/Fastboot mode, there was a progress bar of sorts on the phone itself indicating it was receiving something. On this phone it doesn't display anything to imply something's happening.

Boot into download and let us know what it says on the download screen. If you have the 4.3 bootloader, try flashing a pre-rooted 4.3 Bell ROM using Odin 3.07. If you have a lower version bootloader, try flashing a pre-rooted 4.1.1 or 4.1.2 ROM.
http://forum.xda-developers.com/sho...mctr=(not provided)&__utmv=-&__utmk=139036464
In Odin, don't check auto reboot. When you see reset in the status windows, disconnect the USB cable and pull the battery. Boot into recovery and wipe cache, data, and reboot.

Thanks for the reply! I'm 99% sure it's a pre-4.3 bootloader. Here's what it shows in DL mode:
ODIN MODE
PRODUCT NAME: SHG-I747M
CUSTOM BINARY DOWNLOAD: Yes (2 counts)
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
DUALCOMM SECUREBOOT: ENABLE
If I recall correctly, a 4.3 bootloader would show two more lines at the bottom.

I feel it's worth mentioning again: At no point, while using Odin, does the phone display a transfer bar of any sort.

Try installing Philz Touch recovery via Odin and see if you can boot into recovery. Copy a custom ROM on an external SD card and see if you can flash that ROM from recovery.

Tried Philz and Odin still doesn't seem to have flashed it.
I'll try with an SD card.

Try this: when you flash with Odin, uncheck auto reboot, start the flash process. When you see the word reset in the status window, remove the USB cable, pull the battery, and boot into recovery.

stuck on boot screen with no recovery mode [SM-t320]

Hello Guys!! I'm hoping someone can give me a hand. I got a Samsung Galaxy Tab Pro 8.4 (SM-T320) that is soft brick. If i'm not mistaken the device was been updated via OTA and crashed. Every time i try to turn on the device I get the following message "firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". For some reason I'm not able to boot the device into recovery mode. It seems the partition got damaged. Please note that I'm using the following commands to boot into recovery mode (volume up+home+power). I have tried connecting my tablet to Samsung Kies v2.6.3.14074_11 and use the option "Firmware Upgrade & Initialisation" but at the end of the procedure I get the following message "This version of the device cannot be updated". I have attempted to flash the device using Odin v3.07. The stock ROM I used was T320UEU1ANG1_T320XAC1ANG1_HOME.tar.md5. The Odin PASSED and reset device but the phone did not boot back up. It just gets stuck on the boot screen. I have also tried to flash the device with custom recovery cwmr-20140605.tar. but I didn't have any luck. If anyone has any ideas or solutions, please let me know. I'll greatly appreciated.

I just attempted to use odin v3.09 but I'm still having the same problem. It keeps getting stuck on the samsung galaxy tab pro sm-t320 screen without recovery mode. I have attempted to flash cmw again but the problem persists. I also noticed the battery won't charge anymore. I'm not sure if this was due to a failed flash. Anyone has any other ideas?

Get the cwmr tar file (unzip the zip). Flash it in Odin. When it starts to flash it, hold the volume up key until it shows the galaxy tab pro splash screen and says something like "warranty bit set: recovery".
That should get you back to recovery. If that doesn't work, post a screen shot of Odin after the flash.
If your kernel is broken, which it sounds like it is, it's normal that it won't charge because it needs to boot the kernel to charge even when you "power off".

I managed to get my tablet to charge by tearing down the device and reconnecting the battery. After doing this, i plugged it directly to the wall. I got this idea from a youtube video. Im going to leave the battery charging all night. Hopefully tom its a good day and i have a working device

How did you charge the battery? Maybe a lipo charger?

Im really happy to say that now i got a working tablet. I guess removing the battery did the trick.
'edlabh' thanks for all your help. I was able to charge the battery by plugging it directly to the wall. Please note that i had to take the entire tablet apart and disconnect the batteryfor 15 min before reconnecting it. Thank god im good with teardowns and i dont give up that easy

I already tried flashing TWRP, CWM, CF Autoroot (to be able to install a custom recovery). I opened it and removed the battery for 15 mins. unlike this guy, it didnt work for me. I also tried flashing CM12. The tablet wont turn on without being plugged in and I can only access "Downloading Mode"
Perhaps the kernel is broken, but how do I fix it?
This is Odin's message, after flashing stock firmware.

Install Kies 3 from Samsung and try the tools -> emergency firmware recover option before anything else gets messed up.
Odin is not safe to mess around with, if you accidentally check a wrong option or use any field other then AP, you might end up with perm brick
Sometimes the vol keys are reversed try Power + the other vol key

Also, another thing is the when I plug it in and press the power button it lights up and shows the battery icon with no charge stuck in a loading icon that is not animated.
I will try your suggestion but I had already try (on Kies) Update and Recovery but it didnt work (perhaps because of the tablet being in Downloading mode?)
UPDATE: Kies 3 wont recognize tablet, even in Downloading mode (which is the only mode I can access).
Thanks!

This thread is very old. But I've the same problem, stuck at samsung logo and only get into download mode. Accessing the twrp recovery mode is not possible. I've not flashed the device and the battery had over 90% percent. I started the device suddenly it turned of and it was not possible to start it again. Has anyone solved this problem?

I didn't thought that the battery was the problem, because one time the devices started and showed about 90%, but it was the battery. The batteries are very bad for this device, this is my third one.

Memory Damaged message, won't reset, recovery mode fails (red triangle,Android down )

Hi, I've searched hi and low for help, but can't find anything that seem to apply to my phone or case. I have a Canadian Mobilicity S3 model SGH-T999V that just bricked itself. Everything is official other than I unlocked it to switch to Wind: Binary Count = 0.
The Story: Last week (Tuesday Sep 22nd 2015) The phone restarted a few times for no apparent reason, then the next day errors about missing files started to pop up to the point that I had to reset the phone to be able to use it. Start fresh all good for a week, then one restart yesterday (Sep 30) and this morning I have a screen that says: "Device Memory Damaged - the data partition has been corrupted.you need to reset your device to factory defaults.this will erase all your date. (reset device button)" I press the button nothing happens, so I take out the battery, leave it while at work, then try again: same thing - I try to reboot into recovery but fail: I get a down android with an open belly cover and a red triangle picture for a bit and the phone reboots back to the damaged memory screen. I can get into the download mode, but Odin doesn't see the phone.
Any advice on how to proceed from here would be greatly appreciated.
I've used Odin before on my Nexus S, but that was many moons ago, it's dead now...
Thanks in advance.

Can you get into download mode? If you can, yet flashing the stock ROM from sammobile.com and flash it using Odin.

Thanks for the reply.
Odin doesn't see the phone and I don't remember exactly how to use it either, but I know it's very model specific, as to files and ROMs to download and install, hence the advise seeking. I guess I'm hoping someone in the know can tell me "follow the instructions for such [more popular] model #, that will work on the 999"...

The T999v is a very popular model in Canada as it was used by Wind and Videotron.
Are you able to boot the phone into download mode? The Samsung drivers are installed? Are you using a Win7 machine?

Yes it boots into Download mode but not into recovery. I have Kies installed along with the drivers, could reinstall that just in case. Running Windows 10 Pro Preview, in the process of upgrading to the final release.

I recommend grabbing the latest firmware from sammobile.com for the phone and flash it in Odin 3.07 with the phone in download mode. I would not bother with Kies.

I've updated my build of Windows 10, that may have been one of my problems, now Odin reacts to the phone but fails:

So much for that! guess it's fried at the hardware level.

I'm thinking you are suffering from a hardware failure as stated by the message you mentioned before. It has happened to others and I can't recall anyone having much success in restoring functionality.
If you want to try again though, uninstall kies from your computer as it interferes with Odin. There is also a newer version of Odin, but I doubt that would make much difference on the S3.
If you are unable to get it working again and want a relatively cheap fix, search ebay for a used motherboard or a device that has a broken screen but otherwise works. Then swap out the board.
Sent from my SGH-T999 using Tapatalk

The update is failing because the ROM you are flashing has a bootloader that is older than the version currently installed on the phone as verified by the following stop error in Odin:
<ID:0/004> aboot.mbn
<ID:0/004> NAND Write Start!!

I have a feeling DocHoliday77 is probably right, I've bought a new phone from my provider for 9$ (Alcatel onetouch Pop D3) and posted a wanted ad for broken S3 ... not ready to completely give up on the S3 just yet, but neither do I have high hopes.
Getting rid of Kies
The firmware is the most recent for the SGH-T999V on sammobile.com - I can try without the V maybe

Only T999V firmware will work on the T999V.
If you are selling it and it has a good working display you should be able to get a decent amount for it still. Not sure how much they are going for these days but it's always been the most expensive and in demand part for the device.

Formatted Device

So somehow I deleted everything on my device except for TWRP. I have a refurbished sapphire black 64gb Tmobile s6 edge. Is there a way I could restore it back to normal?

What do you mean by "normal"?
Do you restore all the files that were deleted?
No, unless you made a back folder on another storage area, like a usb-otg flash drive or copied to your pc, those file are gone!
Have you deleted everything including the OS? Meaning your phone will not boot up?
If so, then you will need to download either the full odin tar file to Flash the stock rom using odin with your pc or download, transfer to your phone and flash a custom rom.
That's basically it.
Unfortunately unless you backed up your personal files from your phone that are lost forever.
It sounds like maybe you recently got the phone and hopefully didn't have much on it so take this as a lesson and definitely be careful when checking things in TWRP.
Good luck and sorry to hear that.
There isn't much as far as development in the Tmo S6 Edge forum, but you can check the Tmo S6 Flat forum or check the International Flat S6 forums.
My OZOP Rom is actually build from official Tmo S6 Edge firmware and would suit your devices compatibility perfectly.
Also pretty much any Flat rom will work on your device, just make sure you go slow and read all the instruction and steps posted my the OP.
We write these steps for you, we know how to install our work so again, the instructions are written for users benefit and we take no enjoyment in writing this stuff, especially if you don't read it and post problems!
Major no no! But happens all the time! Very annoying!

I have backups of the original files on my device so I'm not worried about that, I have been trying odin and TWRP flashing and neither have worked, to clarify the phone would show the s6 edge logo go black and repeat until eventually going to TWRP. after I had booted it to TWRP once when I press power off in TWRP it would show the log go black and then go into TWRP. in TWRP I able to boot it into a download mode it only showed the ""Downloading . . ." and "Do not turn off target" and an error in the top left saying "SW. REV. CHECK FAIL. DEVICE: 4. BINARY: 1" From this screen I plugged it into my computer and tried to flash a stock rom and odin would give me the error

Once this failed I was able to turn off the phone by holding volume down + home + power. it then showed the charging image even after unplugged until I held volume up + home + power for it to boot into download mode, this time saying
"ODIN MODE
PRODUCT NAME: SM-G925T
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
FRP LOCK: OFF
Secure Download: Enabled
KNOX WARRANTY VOID: 1 (0x0500)
RP SWREV: B:4 K:3 S:3" in the top left corner
after trying to flash the same rom with odin I got the same error in odin as the one before and another line on the phone saying "SW REV: CHECK FAILED DEVICE: 4. BINARY: 1"

UPDATE: I reinstalled the firmware using ODIN, and found the problem I was getting in download mode was due to the firmware being wrong/not compatible. the firmware that did work is found here: http://www.sammobile.com/firmwares/confirm/89343/G925TUVS4EPH2_G925TTMB4EPH2_TMB/ (posting for anyone who has this problem in the future.)
thanks to stangdriver44 for the push in the right direction.

I need an expert, my phone may be trashed

This is my first time posting here and I am at a complete loss.
My sister gave me her ATT SM-N910A Note 4. It had started this awful rebooting process. She thought that I would be able to fix it, so I gave it a try. It will still not go past optimizing apps. This is only sometimes. It just reboots, reboots, and reboots. She was running on Marshmallow when this happened. The battery has been replaced.
I took it to the ATT store today and they did not seem like they were very interested in helping me. They kind of blew me off. They told me that since I could not get to recovery booting there was nothing that they could do. So, I proved to them that I could, indeed, get to recovery mode by holding all of the buttons down and putting the battery in. He looked at it for a second, pressed a button and he was done with it. He told me that my system files are deleted. That I need to find someone to help me recover them or I could do it myself. SD updating is disabled. I have to do this from Odin.
So, I think I need Odin files.
Please help!

You need to flash stock firmware through Odin.
Follow these steps exactly and hopefully you will recover your device.
Things you will require.
1, windows pc
2, download samsung usb drivers or Samsung kies and install it on your windows pc.
3,download odin tool for pc.
4,download stock firmware for your device.
5,your device battery charged minimum 50%.
6,usb 2.0 cable.
7, winzip/winrar installed on pc to extract the firmware file.
How to flash.
1,extract the firmware file you will get a huge file around 4gb.
2,open odin tool and choose AP Tab And upload firmware file that you extracted (ODIN WILL HANG WHEN YOU UPLOAD THE FILE SO DONT WORRY JUST WAIT 4 TO 5 MINUTES UNTIL FILE WILL UPLOAD )
3,put your phone to download mode by pressing (volume down+home+power button all together) hit volume up when you see warning logo)
4,connect phone to pc via usb cable .
5,HIT START IN ODIN TOOL .
6,once odin shows PASS remove usb cable and battery from phone and insert battery again.
7,boot into recovery mode by pressing(volume up+home+power button )
8,navigate via volume keys to "wipe cache" and hit power button and wipe cache.
8,navigate to "wipe data factory reset" and press power button to factory reset.
9,now reboot and wait 10 to 15 minutes and you will boot into system successfully.
11,Let the phone rest for few minutes then complete setup.
Hope this will help.
Samsung usb drivers link

Odin for windows pc.

Just to be sure, what will happen when it reboots? Will it have recovery booting in the top of the screen? Then reboot by itself? Do you mind if I come back here after I get my daughter from school and get everything downloaded for if something goes wrong?
I will be home in about 35 minutes tops.

It went to the Samsung Galaxy Note 4 Screen and stayed there for a minute. Now it is off. Is this correct?

I had stupid problem with my s5 long time ago. It was sticky power button. I turn off my phone, use drop of alcohol and drop on power button. Then press couple times and let dry for 1 hour or use hair dryer to do it faster. Then turn on. Works perfect after all of this. Not saying tjis is your problem and this will help in 100% but wort to try. Good luck.
Sent from my SAMSUNG-SM-G935A using XDA Premium HD app

So, Odin will recognize my phone, but not my computer. My computer says that the device is not working properly. What is really going on here?

It is not even going to optimizing apps any longer. It used to always at least go to the ATT logo.
Now, it is vibrating non stop while it is off.

Your reactivation lock is on so you cannot flash anything through odin.
Reactivation lock must be turned off to flash.
Only You can turn off from settings/security/reactivation lock and turn it off.
I suggest you take your device to repair center they will take care of it .you cannot flash or do anything because it requires someone who is expert in adb commands to turn off reactivation lock while your device cannot boot.
If your device boot up you can turn off reactivation lock then try odin method that i mentioned earlier.

No way! That is not what I wanted to hear. There is absolutely nothing that I can do for this phone?
Where do I find a repair center?

It said installing system update and got half way through and cut off.

Keep trying to boot into recovery and do factory reset then reboot.

I am going to keep trying. When it does get there (see how I said when and not if, confident) I will come back here. There has to be a way inside of this phone!
The recovery mode looks a little different now. When I got it from my sister, I tried a hard reset. It was red and blue then. Now it is white and yellow and has the option of system/mount(?) I am no expert, but I do believe changes are being made here. I am staying hopeful. I really want to use this phone!

Looks Everything went well but you have to do factory reset from recovery straight after flashing then reboot and wait 15 to 20 minutes on first boot it will take long time.

Okay..
I feel like it is doing something different.
I was able to get into recovery after leaving the battery out while I took my dog to the vet. I got home and it went into recovery. My droid bot fell out dead with his triangle. I pressed the power button and it bought up the menu. I cleared cache and wiped data/factory reset. It turned off talking about verifying some kind of hash tree.. It passed.
Now I am stuck on the Samsung Galaxy Note 4 screen. Is this the screen I need to leave it on for first boot?

Yes you have to leave atleast 20 minutes for first boot.
