[SM-T825][Bootloop] boot looping after flashing official firmware - General Questions and Answers

Hi all, hope ur doing well
I recently rooted my Tab S3 with the help of TWRP and Magisk
All was well and there were no mishaps or errors. One day I decided i did not want it to be rooted so i flashed the official firmware from the SamMobile website.
Ever since then it has been boot looping, even after multiple flash attempts with varying version of Odin and the official firmware
I will try give as much info on the steps i took in order to help you help me.... if that makes sense
1. I downloaded the firmware from SamMobile and downloaded Odin v1.13.1
2. I selected the BL, AP, CP and CSC files respectively for flashing
3. I flashed the firmware successfully
4. Auto-reboot continued
5. Rebooted into recovery
6. Android Logo appeared and text said "Installing Software Updates"
7. Text changed to "Erasing"
8. The tablet rebooted again showing this screen
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
9. After which the boot loop started (showing black screen and above image.... never showing SAMSUNG logo)
After some googling i found that this is sometimes an issue and a quick way to solve it is to boot into recovery and WIPE CACHE and WIPE DATA/FACTORY RESET
I did this but with no success.
After booting into recovery mode i noticed some interesting text at the bottom of the screen
(Apologies for the poor quality)
Not sure why the dm-verity verification failed but it prevented me from trying other methods such as updating via SD card or ADB.
So I thought let me try installing TWRP again and see if i can do anything from there.
So i booted into download mode and flashed TWRP.... only for it to fail and display this message
"Only official released binaries are allowed to be flashed"
Great. Just another quick google search and it suggests that the official firmware is to be flashed before continuing
so i did it ... again (steps 1-9)
and i am stuck where i started this quest, in a boot loop never getting passed the Galaxy Tab S3 screen
If you know what else i can try or what could be the issue, or even a mistake i made that i was unaware of ... please leave a comment
i appreciate any and all help
Thank you for ur time and sorry for the long post
Much love

I'm taking a long shot here, I don't have Odin in front of me but if I remember correctly, you must uncheck "auto reboot" in the options tab

hi @Raffles727
thanks for your advice, I have attempted it with "auto reboot" disabled
but as soon as I leave the download screen by holding the power + vol down + home buttons it repeats the same process from step 5-9 without any intervention from me
did I miss something or did I do it correctly?

[A510] New discovery for my bricked A510

Hi all,
my A510 was half-bricked since I run the wipe option of CWM (version 5.8.4) last month. It can not boot to system, just hang at 'Iconia tab' logo if I power it on.
I tried to flash the stock recovery back, and flash the update.zip from SD. Every time it just stuck in 1/4 of the progress bar. (even change the zip or SD card)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then I chose to install the new CWM for A700 ( version 6.0.1.1 ) and success to enter it. All the options can be run without any stuck, except for the wrong picture. I didn't know what to do, so i did all the wipe and format options.
Then it's getting more terrible, it stuck in Acer logo (first screen) after boot, nothing went further.
Last night I tried the SD flash again. I flashed all the roms from this thread, (I tried all the roms and failed to flash any last time)
To my surprise, one of the rom (1.060.00_EMEA_CUS1) can be flashed!
At first it stuck at 1/4 of progress bar as usual, then after a while it went to the 9/10 very quickly!
It reboot a few secs later and I saw 'updating EBT' at the upper left. Then it reboot again.
At the second-time reboot, I didn't see the 'bootloader unlock mode' shown in first sreen anymore, so it seems I made it?:cyclops:
Then I knew I am wrong, it also hang at 'Iconia tab' logo at last. :crying: oh, come on!
I didn't give up and continued to flash other roms. But i was too tired to sleep.:angel:
When i opened my eyes, i saw my tab entered the system finally!
No, wait! What is it?
title: 'XXXX unsuccessful'(my bad, i can't remember the first word)​content: 4 lines of words, about to tell u the tab need to be reset.
So I hit the 'reset tablet' button at lower right corner, then it reboot to recovery immediately. I saw the whole progress bar became very active and went backwards, and i waited it for half an hour, but nothing changed.
'coz that was midnight, i plugged the charger and went to sleep.
When I get up, it just hang there. damn it.
Anybody know what to do next?
p.s. My tab is EMEA-DE version.
Thanks and Regards,
Jokerzlh

SM-G920P - Stuck on TWRP Screen!

[SOLVED]
So first of all, I apologise if another thread has been created. I have looked around and have seen nothing similar to my situation. I would greatly appreciate if anyone could help me out.
I rooted my SM-G920P device and trid to install the TWRP Recovery. I'm currently on 5.1.1.
It didn't work and I ended up with the start-up screen saying:
SAMSUNG GALAXY S6 Powered by Android.
At the top left it says: Recovery is not seandroid enforcing.
I have tried flashing twrp 2.8.7.1 with ODIN and I end up with the following screen.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The touch screen does not work so I am unable to swipe.
This is the issue I am having.
If I can get my phone back to normal functionality, I would really appreciate it.
Many thanks in advance.
Hi teekeiwong,
Press and hold "Volume Down" + "Home" + "Power" until phone reboots. When you see boot screen, release power key but keep holding volume down + home until you get to download mode. Release all and press volume up to agree to enter download mode.
Download this on your pc and open up Odin.
Connect your phone and add your downloaded file to the "AP/PDA" button in odin. Make sure ONLY F. Reset Time and Auto-Reboot are checked. If anything else is checked then uncheck it before starting.
Click start and wait for it to finish, might take a while for your phone to boot first time after flashing
AFTER you are back to stock, take a GOOD look over here and you might just get a working root & custom recovery
Hope this helps!
- Renolz
Thanks Renolz.
I've been searching forums all over the place. I'll give it a try when I have a bit more time on my hands.
Thanks again.
Also I have another queestion which I hope you will be able to help me with. On my phone when I go to Settings - About Phone, the model number is SM-G920F. However when I go into Download mode I see that the model number is SM-G920P.
What am I supposed to go with?
Also after flashing the Noble ROM to convert my S6 into an S6 Edge Plus, I lost the baseband. I no longer can gain any signal to make calls nor texts. Would you have any idea how to go about this?
Thanks again
Same Issue...

Bricked my wife's SM-P900? God help, please!

Hi,
A few days ago I tried to update my SM-P900 tablet after 3 or more years without updating. I tried to flash this ROM (https://forum.xda-developers.com/ga...7-1-xsm-p900-unofficial-cyanogenmod-t3524788/), but it didn't boot. I flashed the recommended bootloader and recovery with Odin, but I'was not able to boot. Somehow, neither booted Lineage 13 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-13-0-android-6-0-1-t3366834) nor Resurrection (https://forum.xda-developers.com/ga...lopment/rom-resurrection-remix-5-8-2-t3563635). The only ROM I managed to get working is CM 12 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-12-lollipop-5-0-1-t2971945/). I thought that the problem was the bootloader, and someone suggested that I flash a more recent (at least lollypop) bootloader. According to Phone INFO, my bootloader version was P900XXUANI1. I tried again and again to flash the BL_P900XXU0BPA1.tar.md5 file, but, despite Odin showing the PASS! message, Phone INFO kept showing the same bootloader version. After that someone recommended that I flash the most recent stock image, so that I get a recent bootloader, that is what I tried to do.
I downloaded the file Samsung_SM-P900_(P900XXS0BPL2_P900OXE0BOI1_Russia_v5.0.2)_by_ (FirmwareOS.com) from a sammobile kind of site. What I look for is that ...BPL2 version that seems to work for other people. But after flashing it, the tablet doesn't boot and I can't access download mode. The only thing that i get to boot is the stock recovery, but it doesn't have the flash img option nor the reboot in Download mode that TWRP had. The only options I got are "Update from external storage" and "Update from ADB". Either of them don't let me flash a full factory image nor, apparently, another bootloader or custom recovery. When I try to flash it I get "E: footer is wrong \n E: signature verification failed" and if I do it via ADB, the error shows right away after a 0% transfer.

}
EDIT: Other symptoms I found are:
- I can't manage to power off the tablet using just the buttons: it always reboots unless I select the Power off option in the recovery. Also if the tablet is connected by USB to the charger or the computer it always try to boot.
- When the tablet is connected via USB and I try to power it off, the tablet reboots and shows a battery symbol, but is gray and kinda strange.
I'm pretty desperate now. This is my wife's tablet and I tried to update it so that it was more secure. I'm screwed.
Any ideas? Is this fixable?
Thanks in advance.
Regards.
Did you try to download the stock rom which consists of several parts with the samfirm software?
For that you have to check the binary box in SamFirm and to insert device type and region.
Flashing that might work better.
I forgot to update the thread. I managed to fixed the tablet. It turns out the tablet hadn't enought battery to enter download mode and I was messing up with the Vol Up and Vol Down buttons. Really embarrasing. Hahaha. After fully charging the device and pressing down the proper buttons, I managed to enter in Download mode and flash a new image.

Bricked Nexus 5?

HI,
I've attempted to install Ubuntu Touch on my Nexus 5 using the UBPorts installer on Windows 10, all was going well until the installer hung on "preparing system image...".
After rebooting the phone numerous times, the screen remains stuck on black screen with the Google logo in middle and a lock icon at the bottom center and is unresponsive to anything. See screenshot.
Have I bricked the phone irreversibly or can I save it?
Thanks in advance

If you can get into the bootloader, try fastboot flashing the last factory image.

You can follow this guide for the Pixel 2 XL. https://forum.xda-developers.com/t/guide-unlock-flash-root-for-the-pixel-2-xl-taimen.3702418/
Just make sure you use the last Nexus 5 factory image found here and not the Pixel 2 XL factory image... https://developers.google.com/android/images#hammerhead
Follow the "Installing fastboot and adb" and "Flashing factory image (clean flashing a factory image (wipe everything))" sections.
