How to WIPE without CWM / NO recovery / only download

Hey guys.
I have been doing a lot of researches before creating this new thread.
Here is my problem with a Samsung Galaxy s3 I9300T (Australia - Vodafone build). I was given the phone, since it was stuck in a boot loop after a software update issue with Kies (I think from memory 4.2 or something).
The phone boots up, displays the Vodafone logo, and is stuck on the Samsung logo. The phone doesn't restart but stays idle there.
It is impossible to reach the download mode with the use of the 3 buttons, but a USB JIB I bought on ebay does the trick.
Odin recognizes the phone, I can flash a stock Kernel from Samsmobile or root/install the CWM.
BUT, there is no way (so far?) to reach the recovery mode.
I tried to flash a new boot loader, tried to check any physical issue with the buttons, but nothing seems wrong.
I have been looking for tools such a android toolbox/toolkit etc, in the hope one would be able to wipe/flash the nand or even unbrick or whatsoever, from a download mode and not ADB, since I there no fast boot available.
I am ready to try anything, since there's nothing to loose here.
I'm running windows 7 from Parallel desktop.
Thanks mates.

I tried 2 different firmware from SAMSmobile, after flashing in Odin, nothing changes. The phone reboots (if the case is ticked) and stays stuck on the samsung logo, after the vodafone splash screen.

maybe something went wrong in partition table during kies upgrade, do you tried a full system reinstall comprensive of pit image?
myabe this get phone back to life but i think you will lose efs.

Well normaly after flashing your right Firmware you should be able to acces recovery...

How can I perform what you call a "full system reinstall comprehensive of PIT image"?
I have stock firmware, but no PIT file or CSC or whatsoever.
what do you mean by losing EFS? (encryption ??)
Any help is much appreciated.

efs is a system partition wich contains your phone's hardware serial numbers, such as imei, wi-fi mac ecc... losing this means you can't connect to phone network until you restore it(i'm not sure you lose it)
i found this guide here on the forum to restore from brick's or similiar, i think you can try this if normal flashing don't work:
http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367

When you flash full firmware from Samsung (.tar.md5), it includes things such as bootloader, tz, modem, system, cache, preload and the recovery. Just make sure to download it from site such as sammobile, and you can check yourself if your .tar.md5 you're about to flash includes these things using i.e. 7zip.
Untick "auto reboot" option and flash it. After it's done, it won't auto reboot but Odin will change text to "RESET!", this is a signal for you that it's finished.
Hold on Vol-Up+Home+Power for about 7 seconds, until you see Samsung Galaxy S3 logo. It MUST enter stock recovery you've just flashed, unless your hardware is broken. From there you can select Wipe data / factory reset.
Good luck.

Yes this is what I did.
But after "RESET" doing it, holding the buttons won't let me reach the recovery.
Is there a way to access it ? like for instance a USB JIG allowed me to access the DOWNLOAD mode; whereas holding the buttons never let me.

I don't think so. Probably your buttons are broken then.

I still do not understand that NO software is able to address the phone, like the recovery mode does.
We can flash from a computer, how come not to wipe from a computer.
assuming that someone has no screen or broken buttons, i'm sure there's a way to access wipe and/or access the recovery to flash a stock rom.
Thanks

Hey, yes I tried the link, but again I cannot access the recovery to flash the .zip file.
When I hold the buttons as soon as the logo "galaxy s III GTI9300" appears, the screen goes black and the logo comes back again.
If I release one button, the vodafone splash screen appears, and the boot is stuck on the samsung logo.
I assume, the buttons are working because of what I just explained.
But again, I cannot access the recovery.
Last week, for some reason, after flashing I has a "setup wizard" from appeared, and crashed. that was the only time. I could see the lights under the touch buttons coming on. After the crash, I tried to reinstall and couldn't do it.
I am still sure there should be a way to wipe the nand completely or install from the SD card via the download mode.
Any help is welcome

I get same thing(galaxy s3 logo, black screen then normal boot when try accessing recovery) some time ago after installing philz reco, i flashed another recovery and now runs well, it sounds so strange that you still cant get at least stock recovery after a repartition and a full system reinstall... Maybe something get broke in the hardware...

Other kind of boot loop...

Hi all!
Here is a little problem that i didn't solved.
i have a N910F Note 4 that likes to boot loop . I received it as it is and don't know what caused it(i suppose that was a rooting issue because had the knox value 1)
During the all time, PC and MAC were unable to recognize the Note 4, despite of repeatedly reinstalled drivers(older and newer versions) , Keys and Smart Switch were unable to recognize the device, PC is failing to install the MTP driver for some reason. I changed the USB ports,restarted,updated drivers,updated windows etc. -NO RESULT. BUT : Somehow Keys is able to run recovery and initialization and install it on the device while saying Connecting device... , phone also doesn't appear in device manager or file explorer as external drive.NOTHING! Odin and Jodin says ''added!'' and starts the job with no comments
1. I tried different versions of boot loaders with different versions of ROM (all for my specific model) with no result.
The end of the boot is when Samsung logo ,sound and graphic appears but freezes before actually starting OS, then restarts. IT keeps restarting until battery goes off(even while connected to pc by usb!!! ). Then starts to charge the battery normally.
It boots in recovery and download mode with no problems, it did every time i flashed it…
2. I tried different versions of boot loaders with stock roms , custom kernels etc...and the problem was the same
3. I tried to flash with Odin the stock 4.4.4 without problems but….the problem was the same
4.I tried Device recovery and initialization with Keys and here something interesting happened:
First time when i did it, it went over the samsung logo and booted. I selected language,i skipped wifi network selection and i accepted the user agreement. No matter how fast i was moving, the boot loop didn't went over the user name selection which is after the user agreement. Then freeze and boot again.
Second time when recovered with Keys (tried more stuff in the mean time) it went over the logo and started to update like…''updating applications 2of 17'' the max reach point was ''3 apps of 17'' and then freeze and reboot
I am out of ideas so i suspect that the battery might be dead because it gets empty even if is charging while phone is ''boot looping''. I ordered a battery,should arrive soon.
If that don't work…i am gonna spend some cash and sent it to Samsung for repairs (i bet that it won't be cheap because they will probably tell me that is the motherboard fried so they make you pay for being a bad boy and tried to root). Far as i know is not a brick as long as download mode and recovery works just fine.
Is here someone that has any new ideas for bringing this phone to life? Any help is well received , maybe i skipped something….
Thank you in advance.

Boot into recovery and perform a factory reset, it will wipe the internal storage.

Uninstall Kies, and install Samsung USB drivers: https://www.androidfilehost.com/?fid=24052804347849220
Take the battery out, leave it for approximately 10 seconds, enter the battery back in.
Hold volume down key + Home key and power on the device.
Then plug the mobile phone into the computer.
Run Odin as Admin: https://www.androidfilehost.com/?fid=24052804347851815
Then flash the firmware in the AP section.
Make sure that the firmware is for your region, you can download it from Sammobile or SamFirm.

i have the same problem, but mine doesn't let the samsung logo finish when it shows the letter S on samsung logo it goes restart again no sound or anything, recovery is accesible, download mode is also accessible, i can flash official firmware and factory reset but nothing change, still stuck in bootloop no one here in xda knows how to fix it i think.. or they just never encounter something like this
i know how to fix an ordinary bootloops or soft bricked.. but this one is different.. i think there's something with note 4 that causes this..

Yes, it doesn't go after the Samsung graphics , mine does sound. Goes to app updates only after Kies recovery but doesn't go more far than updating apps 3/17 for ex…crushes there and starts over….weird.
One time i managed to actually go to setup menu, choose country,wifi, device name, and there crushed and started over…. So i am thinking now that the battery might be wasted because i saw posts saying that after the 5.0.1 update many Note 4's went to boot loop and the battery change solved the problem. Now i have new battery coming by post.

Hi I had a similar problem but I do not know if that works but always worth a try
1. download recovery - "twrp-2.8.1.0-trltexx"(.tar) cant post link fresh in forum
2. flash recovery through Odin (AP) ( run as administrator)
3. unplug the cable
4. Reboot to Recovery (home+power+wolume up)
5. Then go to Wipe/Advanced Wipe/check the boxes - Dalvik Cache,System,Data,Cache and Swipe to Wipe
6. Reboot to Download Mode
7. Open Odin ( run as administrator) choise the rom to flash
8 Connect the phone
7. Flash Your Stock Rom
8. Reboot
always in Odin load the file first to flash and then connect the phone
sorry for my English

if you can stay in recovery mode and download mode for more than 10mins i think its not battery problem, i think i have corrupted system files, i left my note 4 to samsung service center a while ago i will get it tom, i just hope they wont charge me too much for it,

nah it doesnt work thats the first thing I do, that only work on ordinary bootloop

I was stuck in a boot loop the other day trying to flash a stock ROM to get rid of encryption. I tried all the stuff mentioned in this thread which is just standard procedure but I couldn't get past the samsung logo. What it turned out to be was that you need to go to stock recovery after flashing the stock ROM via odin and do a factory data reset then it will boot to the OS. It worked in my case, maybe you can give it a try.

if you read the above post you will know that we already wipe and factory reset,
btw since i was not able to fix it, it brought it to samsung service center and they also cant fix it so they are changing the motherboard, so far they are not charging me anything and just asking to bring my receipt of purchase so it will be under warranty

I read the post; however, it did not appear as though you did a factory reset after flashing the stock ROM only before. At any rate at least you're getting a new mobo out of it and problem solved.

yes thats the good thing and its under warranty even though im already rooted, with knox 01 and custom binary haha, i was already expecting to pay a huge amount of money but they said they will cover it, so its a blessing, but i hope the OP fixed his problem.

stuck in bootloop

i have read through these forums for weeks and followed steps perfect but no version of Odin will succeed in doing a factory rom flash. i had the s4 rooted and uninstalled the touchwiz not realizing it was the launcher required to boot phone. since this happened i cant do a factory reset and odin will not work. in fact last time i tried odin it put my phone in a bootloop where as soon as i put the battery in it boots and continues to reboot. this phone has a locked bootloader and come stock with 4.4.2 i dont want to post a really long post with a bunch of info thats probably not needed so if more info is needed please ask. thanks in advance

If the phone constantly auto-reboots, then your power button is malfunctioning.
As for the other cases, use a different PC, Windows and/or USB ports. A cable switch is advisable too. And make sure you have the right firmware for the phone.
Any of those factors can make a change.
Also, unless it's a Verizon or AT&T phone, there's absolutely no possible way that thing has a locked bootloader.

I have a bootloop on the Samsung first logo with "Recovery Booting..." in blue on the top left (Samsung GT-I95026)
I have flash TWRP recovery, the phone don't want to boot on recovery, it's just bootlooping, flashed stock firmware with Kies, still bootloop, Odin, same thing
So after searching everywhere can't seem to find anything that can help, I assume it's dead then?..

Is there any way to unlock bootloader in ODIN? I have I9506 with 4.4.2 that was on it at first. Then i have updated it to 5.0.1 in OTA. So you say that I need to flash it in ODIN with 4.4.2 to make it work?

None of the Galaxy s4 phones have a locked bootloader except for the AT&T, Sprint, Verizon versions.

GT-I9506
S/N: RF8F20W841T
PDA: PL2 / PHONE: OJ2 / CSC: OK1 (NEE)
CAN'T BOOT IN TO THE SYSTEM (no matter what I can't make it to boot properly)
CAN'T ENTER RECOVERY (it's showing that's booting in to the recovery but instead of recovery it just restart)
CAN ENTER DOWNLOAD MODE (no problem with entering DM)
What I have done so far:
- Kies recovery with phone model number and serial number (still bootloop).
- Odin flashing STOCK rom from SamFirm download (still bootloop) (single and 4 files flash).
- Re-partitioning (flashing PIT file).
- Reflashing bootloder (still nothing).
- Tryed CWM, TWRP and other Recovery, non of them boot up.
Using those files to flash:
AP_I9506XXSDPL2_CL6069869_QB11747892_REV03_user_lo w_ship.tar
BL_I9506XXSDPL2_CL6069869_QB11747892_REV03_user_lo w_ship.tar

S8 stuck at Samsung logo, no boot, no recovery, only download mode !!!

Hello guys,
I guess I won't be the only one having this issue. My phone went dead suddenly, and doesn't boot. It only give a circle with a lightning bolt but not charging, is it a battery issue ?
At the same time, I can only go to download mode, no recovery, and I can flash via Odin, with success, but it doesn't boot up still.
This is driving me crazy and I am not sure whether it's a hardware or software issue !!!
Anyone having any thoughts on this ?
Thank you.

Turn your phone off. Put it on the charger. Leave it alone for at least 1/3 of the day. I've been using Android for a long time. This usually happens to my Androids, at least once in their lifetime. It should be good to go afterwards.
PS: Make sure your charger works and don't touch the phone. Let it get a good 8hr charge w/o touching a button.
Let me know if this works for you.

HEY brother.
my case is a bit weird
i bought my s8 running nougat used it for 2 days and it was all good , so i received the Oreo update and updated it using the over the air when I received connected to wifi.
my phone started to reboot randomly even for 30 times per day , i tried several things like wiping cashe and the only solution that reduced the problem was uninstalling my installed apps. basically normal apps like facebook , whatsapp , spotify ,and even stock apps like calculator and music player.
today as usual I woke up picked up my phone and it started rebooting so i uninstalled some apps but it kept rebooting.
sometimes it reboots and get stuck at GALAXAY s8 boot screen [ not samsung flickering screen ] and all i had to do to overcome the boot loop is pressing and holding volume down and power button.
but one time it got stuck and boot looped once and for all. I tried to press volume down and power button to make it reboot again and overcome the bootloop but it rebooted and got stuck at the bootloop.
I tried to access recovery but i couldn't access it.
I can access download mode only.
my phone switches on itself when it is plugged in to charge , i can't turn it off completely to charge it while off.
I reflashed stock firmware and it succeeded using odin but the bootloop is still there.
please help me with my problem SIR.
and thank you really a tons.
sincerely,
Zack.

Did anyone manage to solve this? My phone has started exhibiting the same behavior.
Unable to power on the phone unless it's plugged into the charger, but if plugged in just keep boot looping to the Samsung logo.
I've tried re flashing the latest stock firmware, but this hasn't made any difference.

sounds like a typical case of the battery beginning to fail

Flash twrp and a custom rom... Only solution but go to YouTube and check how to flash twrp s8 oreo? Must watch

Flash back to stock, leave the phone charged until 100% then use the stock recovery or flash twrp and wipe cache and dalvik

Thanks all for the suggestions.
I've tried to flash twrp but I get the error "Custom Binary(RECOVERY) Blocked by FRP Lock".
I've flashed the stock firmware multiple times successfully via Odin v3.1.13.1 (G950FXXU2CRF7) but this doesn't make any difference.
I still can't boot up the phone. The only thing I can do on the phone is have it plugged in and go into download mode.
I can't boot into recovery.
If I leave it plugged in it will power on, vibrate, boot loop to the Samsung logo all day. (It does not show the charging circle)
Could this be a worse case scenario and be a hardware issue? Don't want to give up hope yet, since I can still flash a firmware with Odin.

I've flashed the stock firmware multiple times successfully via Odin v3.1.13.1 (G950FXXU2CRF7) but this doesn't make any difference.
I still can't boot up the phone. The only thing I can do on the phone is have it plugged in and go into download mode.
I can't boot into recovery.
If I leave it plugged in it will power on, vibrate, boot loop to the Samsung logo all day. (It does not show the charging circle)
Could this be a worse case scenario and be a hardware issue? Don't want to give up hope yet, since I can still flash a firmware with Odin.

Man try the latest firmware.... If its not working let me know.... Latest with july security patches.

I am currently undergoing this too, except my phone won't flash in Odin.
I have SM-G955U (TMBL)
Did anyone solve this??

It varies depending on what firmware I try to flash it acts differently. All firmwares I try to flash will take a while in "flash analysis" and then to "setup connection" it takes so much time. After wait some time it fails.
I can send you some pictures if needed. When I get home I will.try again and send you the error.
This is what one error looked like trying to flash G955USQK2_Stock_recovery_BoxWares.tar.md5
This is the error.
<10:0/0/004> Odin engine v (ID:3.1207...
<10:0/0/004> File Analysis
<10:0/0/004> Setup Connection
<OSM> All threads completed (succeed 0/failed 1)
Also excuse for PM you, I thought you were going through the same thing but realized this morning during work that it was my post you replied to.

Any Solution??

its Odin mode, not mood LoL
get a fresh download of the firmware youre trying to flash and flash it instead. Get the Frija tool as it downloads the firmware waaaaaay faster than directly from www.sammobile.com/firmwares

Thank you,
Still same issue.
I have now tried another new battery but the same problem,
i am 100% sure it is not Hardware problem.
Samsung always have same these problems but needs much work or using Z3X Box.
Hope for Solution

even after a new download of the 4 files?

Bricked S8s after software update.

Hi. Browsed for ages and always come here for answers.
Here's my problem.
2x S8s. SM-950f.
Updated to most recent software through software update. Both phones were glitchy and crashing and just generally irritating after.
Factory data reset etc. This did not resolve the problems, also led to one of them having issues with FRP (annoying)
Used Odin to try and flash the latest firmware (from sammobile, UK BTU) after flashing both, they reset and powered on. Got stuck at the S8 screen.
Restarted then both were at the "an error occurred during update" screen.
Managed to get back to download screen. Re checked the software and model numbers, even that the bootloader was the correct version etc. All was fine.
Connected to Odin, shows that it is connected, but nothing happens when clicking start.
Now after attempting that, both phones will not power on.
(One will when placed on the wireless charger, but just sticks at S8 screen) and download mode or reset screen can not be accessed. So, not exactly happy. And totally out of ideas
Any suggestions, beyond taking it to a shop to see if anyone can help.

yes .....dont tuch the phones for 24 hours let the battery die ...it will...connect to pc and then try download mode....u may need to press combination for like 1 minute to get to download mode....flash twrp reboot directly into it when odin says successfully .....wipe system data ....dont turn on phone download any custom rom flash and enjoy.....it will trip knox but worth than getting a new board....

Okay, will give that a try.
TWRP?

TWRP install
https://dl.twrp.me/dreamlte/twrp-3.2.3-0-dreamlte.img.tar.html: Download link for twrp SM-G950F (dreamlte)
Just said, wait until your device powers off due battery insufficience. Plug cable and hold at the same moment vol(down)+bixby+power. Then press vol(up) at the warning screen to proceed to odin mode. Let it charging a while like 1 h. Then unplug it and plug it to your pc. In Odin select ap the previous downloaded file. Take your mobile in your hand. With one hand, prepare your fingers to vol(up)+bixby and with the other hand start the flashibg process. Be careful, and take your hand directly from the mouse if you clicked start in odin, and position your one finger to power button, but dont click. If odin start pass, press immidiately the buttons (vol(up)+bixby+power) and let it to start into recovery. If you arrived to recovery, reply to us if not search for help!!!
Good luck

i have the same issue with my s8 but when i boot in download mode the screen goes black but if i press volupe up it connect to odin with black screen you shoud give it a try

Will try that

Okay, downloaded TWRP, can get phone calls nected to Odin but when I extract TWRP it doesn't give a valid file type.
Am I being dumb.
No files appear that Odin will recognise.
Also just shows as "recovery" no .tar or anything

Ignore above. Corrupted download.
Sorted.
Now when flashing TWRP is gets to a fail due to
"Complete (write) fail

Hi you should try flashing official firmware

Not sure what stage your at and maybe some more useless ideas
1. Trying to flash twrp is kinda of useless if you can't get into your system need oem unlock for that.
2. Have you tried taking out Sim card and SD card and reboot.
3. If you can at least boot try smart switch as it has a emergency recovery option.
4. Trying rebooting in safe mode.

All been attempted
