Flash stock firmware on Live Demo unit with OEM lock - Samsung Galaxy Tab S4 Questions & Answers

Hello.
I've got my second Live Demo Unit of Galaxy Tab S4 (SM-T830). I didn't have any problems with first one: I've entered retail mode configuration with 5444 pass and M729Q16K8546 code then flashed stock firmware and that's it: I've got fully functional Tab S4.
New one has firmware build T830XXXU1ARG4_LLK and retail mode is disabled, there is no FRP, no account linked, I can make factory reset either using settings or recovery. But! Device has some limitations: battery stops charging at 70%, I can't remove demo software and device is not updating to actual firmware. I think I can remove all of these limitations after flashing stock firmware.
I'm trying to flash stock firmware but Odin fails:
SetupConnection..
<OSM> All threads completed. (succeed 0 / failed 1)
OEM lock is on according to download mode string and I can't disable it because OEM Mode toggle is missing in developer settings. Of course I've tried all methods that Google search provided: disabled date & time sync, changed current date, rebooted, but that method doesn't work for my device.
What else I can do? Should I wait for a week or I can disable OEM lock using alternative methods?
Thanks in advance.

Waiting for one week didn't help: OEM unlock toggle still missing. How else I can unlock bootloader? Connecting to adb works but fastboot commands don't work unfortunately.

I really don't know the reason but I could flash any stock firmware on another PC with Windows 7 (instead of Win 10). I've tried multiple cables, multiple firmwares, multiple Odins - no luck and only Windows 7 PC solved my problem.

Been googling like hell for a solution to the exact thing. Guess i need a win7 computer and try this.

Ok. So never took time to actually get a computer ready with Windows 7 (and didn't really think it would work so that kinda made me not put any effort into it.
Today I started up one of my old laptops with Win7 on it and tried flashing it with stock rom. First tried again with win10 on my other laptop and with win11 on my stationary "gaming" computer, but no luck, just got (0 success/1 fail) within half a second, no other info.
So, tried it with win7 finally and.... Dammit, it worked right away. Just can't undertsand why, but it did. Thank you for this!

Bricked hx2110 help

I did a rom upgrade on an hx2110 - installed successfully, but now the only thing I can get the pda to do is go into Pre bootloader mode (i.e. Pre-BL 1.00.02 blue screen). SO I tried the universal bootloader method - makes it all the way to the flashing portion but then does NOTHING - the terminal simply sits there saying "ready" and does not upload anything - the program sees the correct communication port (ie. usb01 or whatever). HOW do I force an upload???
Thanks!
Rusty
On another note - I had purchased a working 2110 with a good mobo to replace this one if the flash is not repairable - is that a difficult procedure? Unfortunately, the 2110 I purchased was not working, but this may still be in the books at a later time, so some info would help.
Thanks!

Rusty,
You are so lucky that I experienced this problem and solved it on my own. You did not specify what ROM you were loading, but here is the fix:
First you need to get another pocketpc, hx2000 series like yours that is working.
Put that device into white screen bootloader or pre-BL mode (depending on which device you got to borrow)
Ensure that the battery on that device is 100% charged.
Run the original ROM upgrade for the ROM you wish to install (use PDAViet if it's WM6 and use the HP SP32408 to Run it)
Hit all the Ok screens until it brings you to the one that has the "UPDATE" button.
Remove the working Ipaq from the cradle and place it's 100% battery in you own.
Put your Ipaq into pre-BL mode and put it on the cradle. Press the calendar button to activate the usb drivers.
Once it says "USB", Hit the "UPDATE" button and it will load the proper ROM to your IPaq.
When It is done, perform a hard reset by formatting the PS on the device.
Voila!! Your Ipaq is Un-Bricked!! Put in your original battery and charge it up!
Enjoy!!
Bless...
hi Rustmonkey,
i have the similar things - i made my hx2110 brick when i flashed it with a different language ROM, it went 100% when i flashed the ROM but didn't work at all after that.
the problem is i can get it in the bootloader mode after trying many ways, at the same time the pc can't find any USB device at all.
how to make it work again?
thanks.

You're going to need another hx2000 series to make sure the battery is fully charged - put the battery in and then use the bootloader keystrokes immediately (contacts+itask+reset) - you made need to tap reset a few times while holding the other two to get it to work. After it is in bootloader mode, push the calander button while it is connected to the cradle/usb to get the pc to recognize it

really amazing !!!!!!
I just saved my hx2110 as per your step by step instruction now.
Thank you very much.
ok, well, I thought they were fixed... now one of them freezes at the bootup screen, even when I do a clean reset... I've tried reflashing multiple times to no avail... any ideas whats going on?
ok, got everything working - reflashed the non-working one back to an original 2003 rom - which made if freeze at boot - then upgraded it via pre-bl to 1.00.00.L - from here, it wouldn't do anything after filling the bar at the boot screen, but it didn't CRASH (as in lights out) - so I ran the pre-bl again and ran the flash program for 1.00.00.L again WITHOUT swapping between the 2495 and the 2110 - just put the 2110 in pre-bl and away we went - flashed, formatted, and booted - then proceed to upgrade to WM6 via 1.00.00.H --> 1.02.00.H --> WM6 - works GREAT!!!
Thanks for the help everyone!
Dear All,
I`ve got the same problem but i don`t have a second ipaq.. is there anyway to repair it with out the second device???
Thank you very much

Hello,
I have run into some problems with a bricked hx2110.
I was flashing the IPAQ to a new ROM WM5 (Battery was full and I read all the instructions 10 times prior to flashing). While flashing, the progress bar went to 100% then faded out immediately and it wouldn't reset (clean reset). I put the battery in my friends hx3000 series and the battery I used was completely dead. It did flash to 100% though, but not matter how many times I try 1 + 3 + reset, it doesn't reboot. If I can figure out how to get it to boot, that would be great, but I can't get anything to come up with any key combinations.
To this point all I can do is get into Pre-BL mode 1.00.04. I have tried the below scenarios on two machines, both running windows XP SP2 (USB 2.0) with the firewall and virus software disabled.
http://forum.xda-developers.com/showthread.php?t=330382&page=4
1) I have tried the above links directions and used the the Universal Bootloader (Bootloader.exe). It gets to the point where it says "The PDA should be updating now" or something similar but nothing happens. I don't get any errors regarding communications (it sees the device when I hold the "Calendar" button until it says USB; windows then recognizes the device as "HP USB ..." so I know it's communicating).
2) I tried to use the Bootloader_GUI.exe beta so that I can watch the progress indicator but it just sits at 0%. There are no error messages so it is communicating but for some reason, the device won't let it flash (and the flash utility thinks it's doing something).
3) I tried the original ROM flash from HP (SP29856.EXE) and it recognizes the device, but because the current ROM on the PDA is hosed, when it does it's "verifying" process, it comes up with "?" marks as the model number and when it goes to flash it starts at .1% then says "FINISHED" immediately. The ROM utility thinks it flashed it correctly but it didn't flash anything. I'm guessing that the verification of the PDA failed and forced the utility to not flash.
Does anyone have ANY ideas of what to try? I wish I had another HX2000 series PDA and try the "swap" thing prior to hitting the update button but I don't. All I have to work off of it my sad bricked PDA and a full battery (friend keeps charging it). His PDA is an HX3000 series.
Any ideas would be appreciated,
Thanks!
Are you using a the HP flash program that is specified for your device?
2nd - you might be able to use your buddies device in a swap as well - not sure but its worth a shot - use HPs upgrade program, let it verify, then swap your device onto the same cable - overwrite the firmware in the update program for HIS device with firmware compatible with yours and then hit update - let us know if this works...
I am using the "official" HP flash program specific for the HX2110 (from their website - SP29856), bootloader.exe, and bootloader_gui.exe
I wanted to try my friends, but he won't let me touch his because I bricked mine lol (I swore nothing would happen to his but he still won't let me try it).
Anyway, I just copied over the ROM image (from HP) and stripped out the header (now showing 64 bytes before the ECEC). The ROM is for WM2003. I copied the ROM in binary using psdwrite.exe to an 256 MB SD card. As soon as I can get the battery back, I'm going to try to flash it from the SD card. If this fails, I am going to try to play around with MTTY / USB and manually call the ROM flash and see what happens.
Having another HX2000 series would make this easy (maybe a little TO easy )!
Bootloader never worked for me - but if you can get it to manually call the flash, more power to you good luck!
Well it was worth a shot. After spending the better part of the day with the PDA, I have made no more progress (can't get Pre-Bl to update). The only option I have now is to find someone with another hx2000 series that is willing to resurrect it from the dead for me (PM me if you can help - I will pay two way fare). Until that happens, it's going in the "broken" drawer with all my old comp stuff .
Thanks to all the tips and tricks that is posted on these forums and brighthand! There is a wealth of information on this topic and without them, I would have gotten nowhere in trying to repair the device (granted, I wouldn't have been intrigued to upgrade the ROM in the first place and would still have a working PDA, but that's besides the point ).
Best of luck to you all.
1).download original ROM from HP (sp29799) -extract files
2) download http://upload.dvhk.pl/content.php?id=88892 - replace files
3) flesh device.
bay!
link crash http://upload.dvhk.pl/content.php?id=88892 - replace files
Please it can raise it again, thanks

Hour 3 of unsucessfully attempting to update Rom

Alright I'm finally going to throw a post up, go ahead and get all your "use search" "it's on search" "it was in a thread" out of the way now, cause I've gone through 76 thread pages of reading and searches and I can't find an answer that works.
I am continually getting the ERROR 262 in RUU everytime I attempt to use it to flash.
- I am running Vista 64bit (not sure if that is the problem or not)
- Using WMDC 6.1
- I have uninstalled and reinstalled WMDC 6.1 a total of 7 times
- I have used every single USB port on my computer.
- I have restarted a total of 15 times, both the computer and hard resets of the phone.
- I have tried both the Unlocker (I'm not sure if I have to unlock a second time or not after my WM 6.1 update) and just the ROM Update.
- I have tried doing the forced bootloader mode (Power+Camera+Reset) and simply allowing the program to do it on it's own.
Everytime it drops into Bootloader (3 color) mode, it drops Activesync and then obviously errors out because of lost connection. I've tried simply running the program and never unplugging the USB cable, I've also tried unplugging the USB cable when the DOSprompt part of the batch tells me to. Everything I've read says to do this, but I don't remember doing this for the 6.1 WM Update. It also doesn't make sense.... if you unplug the device, it's going to drop activesync everytime....
I've just updated every program, reinstalled everything more then 5 times, done countless resets, tried every USB plug and nothing is working. Hopefully this is something easy I'm just overlooking -- or something easy like "It doesn't work with Vista 64" so I can at least get an answer.
Again, I apologize if this was answered somewhere previously. I genuinely tried for 3 hours using search, on and off XDA, so that I wouldn't have to post a question thread but never found a "fix" that worked.
Thanks in advance.

Try another computer. It does work with Vista 64 (I've done it many times), but there's no point in beating your head against the wall for this. There are so many things that it could be you might as well try another computer so that you at least now it is the computer and not your Vogue.

You phone is not unlocked and you are trying to flash a custom ROM.
Try following the instructions in this thread found about halfway down the first page of the forum.

Be it locked or unlocked is beside the point. As I stated before, I unlocked it once for the WM 6.1 upgrade and being as I wasn't sure if I had to do it again, I attempted to do it again.
Regardless of if it's trying to flash the ROM, or use the Unlocker, the same thing always happens. Windows Mobile Device Center (ActiveSync) drops connection once the phone goes to the Bootloader (3 color screen), and it errors out 262 (Connection Lost).
I have attempted to give as much information as possible so I can get input on if I'm missing a step or if it's simple bugging out. I will try what gt! suggested and attempt this on a different computer. However, from the information I've given can anyone confirm that I'm at least doing the correct steps -- there's just some gremlin popping up keeping me from completing it?
Thanks again.
Flash via SD card. There are instructions in CodyBear's FAQ thread.
From experience...use a blank or backed up card.

CONNECTION DROPS BUT............ it should be installing new drivers.
When i flash my phone on windows 7 it loses connection when it enter bootloader just like you.
And by the time the drivers for the qualcomm chip on my htc touch vogue gets installed (this is the recognized driver when your phone is in bootloader)
the RUU rom updater/installer times out.
After it times out for me i make sure that the driver for the qualcomm chip (the driver that is seen by windows when your phone is in bootloader) is installed, i run the updater again.
Now it should run through smoothly again.
Alternate method:
Flash by ur sd card.
or
Try a different computer.
start it up on serial mode then plug it in to USB, go to device manager make it search for new devices. Driver should start loading and start RRU, if all else fails use the SD CARD for The Flash
Alright, well now I guess a second question looms. I was going to take everyones advice and attempt to flash with the MicroSD Card, but now I'm having problems with that one as well.
Yes it has to be 2GB or less and formatted FAT32
I always find my original 512MB works perfect for flashing from
as to how to get it to your card...
Extract the ROM you want to use
Find the largest *.NBH file and copy it to your desktop
at the desktop rename it to VOGUIMG.NBH (I believe the caps in naming is important)
Copy that file to the root of your formatted FAT32 2GB or less SD Card
enter bootloader mode and it should go from there.
Click to expand...
Click to collapse
Those are the directions on the FAQ. I have the original 512mb card, formated to FAT32. I went into the Unlocker RAR, found the Voguimg2.nbh, renamed it to VOGUIMG.NBH as instructed in the FAQ. Placed the file on the freshly formatted MicroSD Card, put it in the phone and went to bootloader mode and... nothing.
I attempted putting the card in, then going to Bootloader. I tried going to bootloader, then putting in the card. I tried putting it from USB to Serial and vica versa. Tried hitting all the buttons. Nothing happens, it just hangs out on the 3 Color Screen.
Am I missing something, or am I just cursed to not flash my phone more then once? Heh. Thanks again for all the help.
[EDIT] For clarification, since I don't know if I have to unlock before every flash or not, I'm just attempting to unlock it again and hense only using the Unlocker ROM. It was previously flashed for the 6.1 update, but I figured it couldn't hurt to try the unlocker again so that's been the ROM I've been trying to run currently.

As explained in Cody's FAQ, once your phone is unlocked to flash, it stays unlocked. The only thing you MIGHT want to do other than just flash the new ROM is to flash a stock ROM, then the new ROM.
Go ahead and try putting the VOGUIMG.NBH from the ROM on the card and see what happens. From what I remember, you should have the card in the phone then put it into boot mode. I believe that was what I did for my first flash ever.
What method did you follow when you flashed to 6.1? Has anything changed about what you are doing now?
Also it might be important to know that when flashing via USB on a 64-bit machine the RUU program will give you an error about not working on a 64-bit computer. Just ignore the error and click ok, it will pop up a few times just keep hitting ok and it will work. That error pops up even though it's false.
when i first tried flashing a custom rom, i extracted the downloaded file and when i clicked on the ruu i had the same error... i then tried just running the downloaded file without extraction and it worked fine.
same thing happend 2 me Just run the RUU do not extract files!!!!!!!((-;
Barogi44, JFive1182 -- You are both princes among men.
The Unlocker will only run on the first auto-extract of the file. You cannot run the batch from the extraction folder afterwards, eventhough all it does is auto-extract the contents and then auto-run the batch file.
Out of curiosity... and being infuriated I went and tested this again just to see. On 3 other computers the same thing happened. I have no clue why it would bug out that way... or if it was written that way that's a pretty bad design.
In any case, someone should put that in the FAQ. You have to let it start the process from the auto-decompressing RAR, you can't start it again after the fact by running the batch file from the extracted folder. If it said this anywhere, the 3 guides I read never mentioned that (nore the unlocker's thread at ppcgeeks) so I didn't catch it.
Thanks again for everyone's input, and obviously JFive1182 & Barogi44 for actually letting me know how to make it work!
your welcome

Asus Zenfone 2 ZE551ML - tried to change firmware from CN to WW, huge problem.

Hi guys, I have a big problem with my Asus Zenfone 2 ze551ml. I bought it from china so I didnt have Google Play and I used to download every app I needed from Aptoide. But yesterday I decided to give it a try and change the firmware. I read every article on "how to", most of them were saying the same steps, so I started by downloading everything I needed, the WW firmware from asus site, the usb drivers, the adb program etc. Everything was going great, and I came to that point that you just have to send via adb the package with the WW firmware and... my laptop(which is an Asus, lol) stopped recognising my phone. Then I started reading tons of threads on how to fix that problem but nothing. I did everything.
Download the intel usb drivers for android- done
Manually install the usb drivers from Asus- done
Uninstall everything and trying one driver at a time- done
Usb debugging-MTP, all these things again and again- done
Tried every single usb cable and port- done
Tried 3 different computers- done
Wipe cache partioning and try all the above steps again- done
Wipe all user data back to default- done
And nothing.. I mean nothing, my phone is invisible to any computer. Is anything else I can do? What's left? To throw my phone away? Now everything in my phone is tiny, the app icons are tiny, the fonts are tiny, even the fb messenger bubble is tiny.. pls help me.. :crying:
my problems and solution for you
Hellooo, not all hope i lost...
Firstly the problem I have similar to you is that my ZF2 runs on CN firmware, which is the biggest struggle ever trying to find the only working APK app files, I was happily trying to install WW firmware (even though it had the playstore, as it was some sort of modded brand new phone front eBay) and I accidely pressed the button which wipes everything :') So I go 3 days figuring out how to make my phone start as another issue had arrised, I fix it with some 3rd party bootloader...and ever since January I've been living this almighty stuggle.
FUNNY THING IS...I KNOW EXACTLY HOW TO FIX IT...but my Acer laptop has an old version of the ADB driver which I cannot get rid of OR UPDATE and I have no access to another pc
As for your issue, by some miracle you read this...
1) make sure you're using a data cable (one that shows you're phone in the Windows library list n all)
2) if you're not seeing or hearing what I said...go in your phones setting punch the fu...I mean tap the "about " option right at the bottom 7 times, and you should now have unlocked the Dev Options...
Now, back to the settings list, press Dev Options which is above the about option, scroll down a little and enable "USB Debugging" press yes/allow...what ever the **** comes up and looks good and wulluh.
3) Now, if actually you've already done step 2 and have tried 3 laptops :0...try step 1 again
4) If you followed step 3s very very complex instructions to a level of hope that binning the phone or suicide are options then by all means set it on fire then throw it at your ex gf...if you have one...concidering you bought an Asus phone lol, mug
5) try this other thing that works but is just as hopeless by finding it on YouTube, searching "Asus ZenFone2 Flash" with the "past month" filter there should be a video with the thumbnail of an Indian man with a blue shirt and glasses, click on it...watch closely n stuff.
Hope it works out and that you found my profecional instructions helpful - Lewis

That's his issue, same for me, ADB does not show in device manager. Unless you mean installing the driver by right clicking on the phones name?

Corrupted Device after downgrade attempt from 9.1 to 8.1

Hi, first time posting so I hope this is the right place to request help on this.
My device had some issues before attempting the downgrade, mainly it wasn't charging with the included cable/charger tried factory reset I could charge it with a Type A - Type C cable but super slowly, even from another charger (with the device still locked) 2 times but the issue wasn't solved. Figured it could be an issue with Android Pie saw reports of people with the same issue (and even the same solution - Type A cabe) so I decided the try a downgrade.
My bootloader version initially was TMZ20k, when I saw google's factory images page saying the unlock_critical was only needed for versions TMZ20a or bellow I skipped that version (didn't know there was downgrade protection for Pie), after many attempts I finally managed to get to the developer options to enable the OEM unlocking so then:
fastboot flashing unlock
downloaded the latest 8.1 (July) and unzipped the contents of the folder within into /platform-tools
flash-all
Problem is, don't know if this happened the first time also or just the last time I tried this (already tried multiple times at this point) but when it starts flashing the vendor.img the following occurs:
'Sending vendor_b' - 'FAILED (Write to device failed in SendBuffer() (unknown error))'
All other steps work normally
I also tried:
Flashing each image individually
Using another 8.1 Image
Use Recovery from bootloader after flashing the image
I could not:
Use another cable or port: Could only get my computer to recognize the device using the original cable and the single type C port I have on my computer
The result is the Corrupted Device screen is prompted and then it gets stuck on the G logo screen.
What should I try? Did I do anything wrong?
The only thing I can think of at this point would perhaps try to run this from another computer. Would that be recommended/required?
Sorry for the long post, just wanted to be as descriptive as I can

I'll try to address a few points. One is that a downgrade is not going to solve your problem and Pie doesn't have a known charging problem. Some (read: a small number) have developed issues with the USB-C port. The issue manifests itself as not recognizing cables, transmission errors, or charging issues. Sometimes it just needs to be cleaned, and other times the port is bad. Inspect the port and clean if required. Second, you should have used BOTH unlock commands separately before starting. This forum is riddled with issues of half-unlocked phones. Everyone has a reason they don't want to unlock critical, but it is always that group that have issues. I suggest you try to get the phone fully unlocked and then flash the latest full (Pie) Google image and continue your diagnosis. Be very careful cleaning the port and inspect your cables. If you cannot flash completely through the full image with zero errors, yes you should try another computer. Lastly confirm your PC is using the latest (28.0.1 (September 2018) fastboot/adb binaries. If after wiping and installing a full image successfully you still have the original problem, it may end up being a hardware issue with the port which is repairable. Best of luck.

This post is golden!!
use Deuces script and flash the required factory image, solve most of the issues

Locked bootloader, cannot OEM Unlock or access USB Debugging

Short version of question: How can I unbrick my ONEPLUS 3 (A3000) if I cannot boot to Android and OEM Unlock AND USB Debugging both have not been enabled?
Long version: Phone was recently purchased second hand from a third-party market (Kijiji, kind of like craigslist for Canadians). Person I bought it from claimed in the ad that the device was in a bootloop and couldn't access the OS. I had in the past successfully saved a ONEPLUS 1 from bricked status, so I didn't feel a simple bootloop would pose much of an issue. That, and at the price he was selling I really couldn't turn it down.
I tried various different methods of restoring the phone's partitions, OS, and firmware to stock/custom, but had no real luck with any (I will list below what I have attempted). If there was a root cause of this, I believe it's due to the fact that some part of the phone's storage partition (boot or system if I had to guess) had become corrupted at some point. Given the volume of threads I've seen here and elsewhere online, I wouldn't rule out a bad OTA flash, but doesn't really matter. What does matter, however, is that the Android OS is inaccessible despite my best efforts, and the bootloader is set to locked and ADB Debugging remains off.
Generally speaking, is there a way to access Developer Options to correct both these issues through terminal or a tool? I'm confident that I can get my device working again if I could access this menu, but as of yet I have had no luck.
Methods used to restore/info worth mentioning
While I don't doubt their effectiveness at large, for whatever reason I have yet to find a tool/guide that yields the anticipated results upon completion. MSM Download Tool (V3 and V4) have both been downloaded, executed, and completed numerous times, but will still not boot past the loading screen upon completion.
According to Unified Android Toolkit, my device build is being detected as "OnePlus3 7.0 NRD90M" and All-in-One Toolkit is showing that Android 6.0.1 is installed.
Drivers are all installed correctly, as proven both via tools downloaded and through Windows CMD terminal (adb devices, fastboot devices, adb get-state, etc)
Stock recovery and bootloader modes can both be reached through both hardware keys and software commands. I will note that it seems to take longer than I'd expect to boot to either of these modes using hardware keys.
I have utilized multiple USB ports, Type-C cables, different OS' on two laptops (MS Windows 10 and 7, FWUL Linux). I usually have no problem with the device being detected by the system. When I have, it usually involved one pesky USB cord.
common commands used and their effects:
fastboot OEM unlock: fails, cannot be done remotely
fastboot flash x: fails, remote: flashing partitions not allowed
ADB push: fails. cannot access partition
ADB devices: device is seen by system with serial and state
fastboot devices: device is seen by system with serial
ADB sideload: varying results. Some will fail at 0% citing "total xfer: 0.00x", some will reach 47% and fail (always exactly 47% oddly). Generally if the sideload operation passes 47% it will complete.
fastboot format/erase x: fails, partition formatting/erasing not allowed
fastboot continue: executes, but does not help with android bootloop issue as I had hoped
While I searched for an answer online, I did come across an infosec whitepaper regarding ONEPLUS 3 vulnerabilities, though it was over a year old. To my surprise, the command they had been entering works on my device, but I'm not sure how to properly use it effectively. The command used was fastboot OEM boot_mode [rf/wlan/ftm/normal]. Now, I was unable to determine what each of the triggers does, but what I did discover is that with boot_mode set to rf, my device would display chinese/korean lettering in lieu of the usual ONEPLUS logo with "powered by Android" below. This is also how I managed to have my device show up in CMD terminal for ADB commands to be issued. To the best of my knowledge though, there doesn't seem to be much point to it as I couldn't push/pull any files. Does anybody know where I could find more info on this command, as I'd like to know what the other triggers accomplish.
I've just about exhausted every available resource looking for an answer, but im still coming up short. I've gone as far as contacting ONEPLUS directly, but without proof of purchase they can't (more accurately won't) help me. And while it's not a business practice I would personally support, I can understand why they have it implemented. I've contacted a few phone shops in the area, but none have been able to assist me further than I've already gotten in this process.
I apologize again for creating a new thread about this, but I felt my circumstances warranted a new thread due to the bulk of the others having either an unlocked bootloader or TWRP installed, neither of which I do.
So, can anybody offer their help or suggest something I haven't already tried? Or should I be on EBAY looking for motherboards? Thanks in advance.

Thanks for the exhaustive description. You seem to have covered every known method. If the MSM Tool also fails, I think that it is a hardware issue and you are better off searching for a new motherboard instead of wasting further time on trouble-shooting.
Best of luck!

I was afraid of that..... is there a way to test a given hardware component?
Have you tried the unbrick tool FULL updated: https://mega.nz/#!NmhhgZyB!CM7Fw8VjECiMIhh4gRXUx24QVCiE599_ZFAPDf08AiM

Indeed I have, dozens of times between the full and mini versions. I've even gone as far as running the toolkits featuring MSMDownloadTool v4.0 to see if it achieved different results (it did not). The mini tool would finish doing its thing (turned the text green upon completion),but I would face varying partitions not being flashed correctly. The full version completes and does not have these varying partitions missing, but the device would then be either stuck in a bootloop where it will eventually reboot itself, or would hang indefinitely on the "swirling dots" loading screen. I tried the remedy of deleting cache in recovery, but this did not help.

***UPDATE*** - As I mentioned in this thread earlier, I noticed a discrepancy between the variant type listed on my actual device and the variant type returned when queried via fastboot. This got me thinking, and to make a long story somewhat shorter, I found that while most stock Oxygen images I attempt to sideload onto the device fail (at precisely 47%, oddly), I was able to sideload two different Hydrogen images without any resistance at all. I'm guessing something to do with the eMMC vs UFS file storage systems and how each OS uses them.
So I got Hydrogen flashed onto my my device. Smooth sailing, right? Afraid not. Despite fastboot's output clearly stating it was a successful transfer, and the stock recovery on the device echoing this, I still cannot get the OS to load. Now i' stuck with the loading screen hanging indefinitely prior to animation occurring, so basically the static ONEPLUS logo. Factory resets and cache wipes have done nothing to help the situation along. Conventional wisdom from the threads here seem to say using the MSMTool is the right answer..... and thus the circle of frustration is complete with me arriving back where I started. Does anybody have another suggestion I can try out? Still can't flash/boot to TWRP, unlock bootloader, or access Android to activate USB Debug/OEM Unlock either btw.
Have you tried flashing just the firmware, i havent flashed in years but i would assume you could sideload the firmware as well?

Guess who didn't read? And after a year without flashing + a lack of reading skills, you still think you could solve this case? That's a spirit.

You better do pm some devs in dev section and point them to this thread and see if they can help, if you are still curious.
My guess is dead emmc, it can be replaced without buying the whole board.

I did read it, its funny always someone who has to be a **** about things. I should have been more specific. He was able to flash h2os. So he could try to flash the firmware for h2os to see if that gets it to boot.

Magnificent, bro.
You're a truly genius.
