T710 stuck in bootloop

Hi,
I am trying to fix a broken SM-T710 which is stuck in a boot loop. I have been working on this for the last 24 hours and I have not gotten very far. I would be very grateful if someone could tell me what else I can try.
First, here are the symptoms:
Holding the power button while the tablet is not plugged in will cause it to show Samsung Galaxy Tab S2 powered by android, then it shuts off.
Plugging in the tablet starts a bootloop, flashing the same message as above, shutting off, and repeating
I have not been able to get the tablet into recovery mode
I can get the tablet into download mode (home+vol down+power)
In download mode it says:
ODIN MODE
DOWNLOAD SPEED: FAST
PRODUCT NAME: SM-T710
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
Secure Download : Enabled
KNOX WARRANTY VOID: 1
RP SWREV: B:2 K:0 S:0
What I have tried so far is connecting the tablet into my PC and running Samsung Smart Switch. I did the emergency recovery and initialization within that software. After entering the model and serial numbers, it downloaded the software update and initialized it on the tablet, I could see the progress bar on the tablet during the initialization phase. It successfully resets the tablet but then the boot loop begins again.
I also tried downloading the firmware from Sammobile and flash in Odin. The file I have tried flashing is T710XXU2BPB1_T710XAR2BPB1_HOME.tar.md5. ODIN flashes the files and resets the tablet...back into a boot loop. I have not tried checking re-partition when I do this, as I do not know what to do about the PIT file
Is there anything else I should be trying? Thanks

Just flash using your original firmware.

This tablet came from eBay so I do not have any idea what the original firmware is. Everything I know about the tablet is in the first post. I assume that Samsung Smart Switch downloaded the original firmware since it required the model # and serial #. I am guessing that the tablet is from the USA but I do not even know that 100%

It's a hardware failure. Several others have had the same issue. Main board needed to be replaced.

I have the same issue here. It's a T715C which I bought in Singapore (distress purchase, rather than bargain hunting) and brought back to the UK.
Given that it's more than a year old, but a known fault, does anyone have any alternatives to taking it to the local recycling centre?

Try NAND erase while installing the firmware with odin.
I'd also try installing kitkat firmware if you can find it. Sometimes a downgrade fixes issues. You can then upgrade as normal.

Thanks. I'll have a Google and work out what that means. All my (many) Android devices have always been unrooted and only upgraded OTA!

Hang on I had a bit of a brain freeze there. The earliest firmware will be Lollipop.
Try the Hong Kong firmware. Instructions to install are on the page.
https://updato.com/firmware-archive-select-model?record=E4B33EF21DCD11E6949E0CC47A44B7B2

Worth a try, I guess. Used Odin to flash the oldest Lollipop firmware I could find - with the NAND Erase All option - and it all seemed to work, but came back in the same state - six seconds of the boot splash screen followed by a second of black screen and repeat...
(Tried Marshmallow ROMS, too - no luck)

Note 5 Laggy, Wifi Issue, and Security Notice

I recently bought this tmobile phone running the latest 6.0.1 version on CG, then I had a google bypass lock and imei fix service, now my phone has a "security notice unauthorized actions have been detected" pop up message and it's laggy every 10-15 seconds, and also forgets wifi password as well. Does anyone know how to fix this? Would I have to flash Marshmallow and reinstall the stock firmware? Would anyone be able to provide an advice for me? I appreciate it!

Means something is on the system partition that ain't supposed to be there stock. Flash stock firmware it'll go away or root and delete security log agent in system/app

Thank you so much for getting back to me. Appreciate it alot!! I looked on samfirmware and there seems to be 4 versions of stock firmware for marshmallow, which one do you reccomend, the latest or the earliest? Which ODIN version should I use? I tried odin 3.10.6 and 7 today along with N920TUVU2DPD1 for T-mobile, which is the earliest version and I got a "SW rev check fail device 4 binary 2" on my note 5 screen on its downloading mode as a result. What do you think that means?

PD1 firmware is really old. Like the very first 6.0.1 update lol
You need to just fllash something newer. The SW rev check fail is just saying youre flashing a firmware thats older than the one you have installed and blocking it.

N950XU (LDU) Flash Fail

Hey all. I decided to pick up a Note 8 Snapdragon variant LDU on eBay to see if I can get it to work on a stock rom. After researching through numerous posts on XDA and videos on YouTube, I took the plunge and decide to see for myself. I wanted to use a stock rom to get past the 70% battery cap on LDU's.
Some people claimed they were able to get it to run a stock rom and some failed. (Yes, this is a LDU. I bought it from a liquidator on eBay).
Here's exactly what I did (I've tried flashing many different roms, but to no avail).
1. Tried to enable OEM unlocking through developer options using date method = did not work.
2. Found me2151's thread on rooting Snapdragon variant of Note 8 = bootloop with QVPASS = 1 QVDONE = 1 prior to Samsung Note8 logo
3. Found a comment on me2151's thread saying they had the same bootloop... Solution was to check "phone bootloader update" (link here)
4. Tried above method in the comments and checked phone bootloader update = did not work, still on bootloop
5. Downloaded a stock rom for N950XU with Frija. ROM is N950USQS5CRL1, released 2018-12-27
6. Flashed the rom using ODIN v3.13.1_3B patched = did not work, "Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost."
7. I'm still able to go into download mode despite that error, but I have no idea what to flash now...
Any help is appreciated! Just want to get it to boot to Android, don't even care if it's the retail rom.

Hey ,I have the same issue, also bought the phone from a liquidator last week, Did you find any workaround?

We might have bought it from the same place then.
Which bootloader version is your phone on? If you didn't flash a newer ROM and is still on bootloader rev 1, then you may be able to fix it.

hi, i was able to remove modem fail error by flashing a modified version of cp file

Really desperate for some help guys flashing note 8 stuck in boot mode:

MY skill with Android flashing: 3/10
Phone Problem: Boots to the very first screen with the phone model and then turns off itself, vibrates, and relaunches..... (repeat repeat). It did use to reach the Samsung screen before my (what I thought was) successful FW flash!
Hey, so im having a mare trying to flash some firmware on my friends Note 8 using Odin3 and pretty much guessing at firmware to fix this phone. I downloaded the latest version that seems to be available.
The phone Model number is not known exactly but its a single sim, UK spec (Carrier: 02) so am assuming it is the SM-N950F
Im slowly downloading fw files to try and get this phone to reboot - but no such luck! is there anyone with enough patience to try and help me install the "correct" firmwares?
I tried with my first attempt and it fails in odin with a message: SW Check boot loader 14 binary 13 (or something along those lines - which I tried a search for here in the forums and was something to do with the compatibility of the bl and fw not being correct)
My second attempt was a success through Odin (Cleared and Pass!) but now it only gets to the very first screen and reboot loops straight away without getting to the Samsung screen.... so not really a success my end!
Can anyone help a Android noob?
Not looking to keep any data what so ever Just want a full factory reset.
Phone last worked properly on 23/24th December last year and my friend hasn't bothered with it since when it bricked.

Hey bro I am not a pro either at this but doing this since quite a time now,
Your first attempt failed because you tried to install an older version of android whereas your device had a newer version installed previously....SAMSUCK does not allows you to downgrade your android model...
Your second attempt resulted in a bootloop , I will suggest you to reboot the phone into recovery and format it once, it might work.....

how do I do this?
I can get into the boot menu and have tried all options as in:
Wipe cache partition
Wipe data/factory reset
reboot system now
still stuck in boot loop (1st power on screen)

Like all four options it gives you in Odin. The bl, ap, cp, csc....... using the latest one I could find on SamMobile for 02 carrier U.K. -

It should boot after flashing that, it could be a hardware problem preventing a successful boot :-( Probably worth trying different filmware though, you could try BTU (UK) or XEU (UK & Ireland)

Bro i will advice you to just get over this stock rom and install some custom rom.
You can install a custom recovery like twrp through odin and then using that recovery install some custom rom made for your device.
All these you might find in your device's xda forum.

Brp i just checked and found that galaxy note 8 has plethora of custom roms available just install the one which you like.
You can see the installation process on youtube.

Samsung Note 8 Has no IMEI and can't get any cellular signal.

Greetings!
New Poster here. I recently bought a used Note 8 on our local marketplace here in the PH and was not thorough enough with scrutinizing the device. (Yes, I'm a total idiot.) I noticed once I got home and plopped my sim in that it was not getting any cellular data. I later checked the about phone section to see that the IMEI and Baseband numbers were missing. Now, I'm not very savvy with cellphones. Any idea on what I could do? I also noticed that on the back of the phone there is a model number SM-950N which is a Korean variant. However, in the about phone section it says SM-950F. From my very limited know-how; I thought it must be flashed with the wrong firmware or something but again I don't know much really. I can't return the device already as the seller won't respond to my messages.
Hoping to hear any suggestions on what I can do.
THANKS!

It seems you have brought a phone that is made up of different parts from different variants put together to make the phone work. I would usually suggest flashing stock filmware as this can often resolve the issue of the missing IMEI but I can't suggest that here as I don't know what filmware you should flash and there is an increased risk of bricking the phone in doing so. A very long shot but you could try a factory reset, with the phone off hold the power, Bixby and volume up buttons at the same time until a blue screen appears then wait for about 20 seconds for the recovery menu to appear then select factory reset.
Can't the marketplace help you? Did you pay with PayPal so you could open up a dispute?
If you come to a point where there is absolutely no way you can get a refund you could try flashing the filmware N950F but only do this as a very last resort as if you brick the phone there is no way you will then get a refund. (Just download the same or newer filmware than what is already on the phone as you can't flash older filmware, if you Google "Frija XDA" you can download the PC app to download the filmware at a decent speed and for free)

Post a screen shot of your download screen.
Download mode should tell you your model number and what mininum firmware version to flash. Download mode is hard encoded and a lot harder to change.

Not really sure what I'm looking at.

I would say you phone has been refurbish, which means someone has made modifications to it. What modification are done who knows. Since the N and F series seems to be Exynos chip set interchanging firmware is possible.
In your download screen :
doesn't give a model number so not much help there.
WARRANTY VOID: 1 (0x030c)- means your knox is tripped ( been modified )
RP SWREV: B : 15 K : 13 S : 13 is the firmware version. The B: ? is the bootloader version number. Firmware has to be this version or higher ( cannot downgrade BL numbers ). Bootloader version will be the 5th number from right of firmware name eg: N950FXXUFDUF1.
Bootloader number range from 1-9 then 10 is A, 11 is B, 12 is C and so on. Since from your on BL 15 you will need firmware with F or higher. Looking at sammobile the only option is to use F firmware as the rest have lower BL numbers.
Note: N950? in the firmware is the model number.
As @stonedpsycho said you can try to flash firmware with odin. If odin doesn't work then try patched odin or try to get your money back.
