Real Rom Install Issue Re. Trickdroid

I was talking about this problem over in the trickdroid thread, simply because it was trickdroid I was flashing but in fairness to that thread I don't want to clutter it with an endless amount of questions, repeating myself over and over, when people are simply there to review the rom/tweaks. I will give my issues in the correct order as best as I can remember, bottom line is I'm caught in a TWRP bootloop.
1) Picked up phone and unlocked bootloader and rooted via all-in-one toolkit. Confirmed root by downloading Titanium, so at this point I am stock rooted with zero issues.
2) Having installed latest TWRP at time of root I immiedietly backed up the stock rom, which I then copied to computer, so I do have this backed up and it's also visible (though unflashable) in TWRP under internal storage.
3) Flashed Trickdroid, which hung on 'install,' and I've since found out there is an issue with aroma installer. Tried 100 times (no exageration)since then to flash that rom and it gets to 30% installed and then reboots into TWRP. TWRP won't then let me do anything of substance. TWRP is also telling me I am now unrooted when I attempt to reboot into recovery from within twrp.The exact order is, flash rom - gets to 30% - reboots into a white screen (not recovery) that says HTC One, quietly brilliant, and then within 10 seconds it automatically reboots into TWRP.
4) On recomendation from rom developer, attempted to flash CWM via fastboot and it flashed fine, fastboot states the flash is sucessful but then when I reboot into recovery it's still TWRP. So CWM appears to have flashed but hasn't for some reason.
And that's where I am. Tried to flash CWM, tried to push rom to sd card, no luck.
Any ideas?

Try to flash without aroma... Replace the meta inf folder with the one linked in the op so it doesn't utilize aroma

Tried to do that yesterday and it wouldn't push. Trying again right now so I can give an exact error message.

What do u mean it wouldn't push?

OK, I've followed the instructions and now have a zip ready to be pushed/flashed.
My question is, would you reccomend flashing it directly to device in fastboot or push to sd card and flash from there?

Okay LA. One quick and very basic question? You said you rooted the phone and you know because you downloaded and installed Titanium. Titanium does NOT need root for simple backups so that is no way to make sure you have root. To verify root, when you boot into bootloader/recovery, make sure it says "unlocked" and "tampered" at the top. I know it is basic but nothing will work without it. If it shows that, we can work from there. You should be able to just copy the file over to your SD card on the phone if your computer sees it.

Make sure it zips up properly and try again. If that doesn't flash try flashing the original zip
Sent from my HTC One using Tapatalk 2

Hey, Mike
We can take this here from PMs
Not sure on the zip you are trying to do, but would still try to get off twrp 2.5.0.0.
and fastboot the 2.3.3.0 twrp image i sent you. then try flashing rom after all wipes in recovery, not aroma. and make sure you fastboot the boot image from command window right after you flash rom. then erase cache then reboot to bootloader then reboot system. usually after first boot I reboot again wipe caches then reboot system--

I take it that letting the battery drain didn't help? Does ADB find the phone now? by the way, without S-OFF, it is almost impossible to brick your phone so we'll get there eventually!

Rug, firstly, thanks for going above and beyond, you're a credit to XDA and I for one really appreciate your help.
Now the weirdness: flashed the TWRP image you gave me and erased cache and rebooted into recovery and it's the original twrp. It definetly flashed correctly, said 'flashed' 'ok' so that is really weird. It simply isn't sticking. And just to clarify, fastboot sees the phone and everything went as it always has, except the end result.

Letting the battery drain is easier said than done on this bad boy
I'm down to 45% and not charging at all so as soon as I get to zero I will let you know. I'm actually starting to pin too much god damned hope on that! lol

Ok when you flashed CWM in the bootloader you complained that it still booted into TWRP, did you try flashing it again and then erasing cache while still in fastboot then booting into the recovery?

boy this is a stumper! Can you reflash the original stock ROM and relock the bootloader and see if you go back to at least a working phone? Then you can unlock the bootloader again choosing CWM this time and then try to reflash TrickDroid? Also, do you have Superuser installed? I think you said you did. Just see if you can start over to at least recover your phone. Something went wrong with the initial steps to cause it to freeze up like that.

When flashng zip without aroma I get this error in cmd:

Superuser was installed but when I reboot into recovery I get a message from twrp saying 'you're not rooted, would you like to flash SU now.' When I swipe to flash it does nothing, although SU is on internal storage.
Just to add, the backup I made is visible in the TWRP folder in storage but cannot be accessed, and when I hit the restore button nothing is listed.
Regarding reflashing stock original, I'd pay 100 bucks to anyone in this thread who could get me back to stock.

[Q] OTA update on stock ROM, but custom recovery

Good morning, all:
I just got my HTC One the other day and, in the process of transferring content from my Galaxy SIII, I rooted and installed CWM recovery, but kept the stock ROM because I liked the change from what I'd been using on the SIII (CM).
Unfortunately, in the last day or so, an OTA update was released for the One and, as I found out (and you likely know), you can't perform OTA updates with a custom recovery. The constant notifications are enough to make me want to update, besides the obvious benefits of increased stability.
I was wondering if I could flash the recovery found in the [Recovery] Stock HTC One post (http://forum.xda-developers.com/showthread.php?t=2158763) to the device so that I could update? Also, would this break my root/superuser? The device is a TELUS model (if they differentiate by carrier) with software no° 1.29.661.5.
Any advice would be appreciated. Thanks!

Hey, guys:
Sorry for all of this noise, I figured things out and wanted to delete this thread, but can't seem to do that.
For those of you experiencing similar issues, who followed mike1986.'s Complete Flashing Guide post, the process for restoring your stock Recovery image to do OTA updates is actually super simple:
- Connect your phone to your computer and pull the backup you did of your device before flashing the custom recovery image.
- Open the folder and move the Recovery.img file to your Android SDK folder.
-Boot your device in fastboot mode (like you did during unlocking bootloader - power off the device and turn it on using power + vol down buttons and select "FASTBOOT")
-Open up command prompt ( Start > Run > type cmd and hit enter ). The window that appears is called Command Prompt. <click here to see the image>
- Navigate to [your SDK directory] (type in Command Prompt: cd c:\[directory]).
- In the Command Prompt type following command: fastboot flash recovery recovery.img
Click to expand...

Using this method, you could flash your stock recovery back onto the device, perform the OTA, then flash the custom Recovery.img back onto your device all in the span of 5 minutes.
This is probably standard stuff for most people on this forum.

[DELETED]

Could you please post your custom recovery?
I need to do the same procedure as yours, and I am currently on same fw, from Telus.
Many thanks.

Sure thing, millicent.
Tried attaching it to the post, but that wasn't working so here's a DropBox link: HTC One Stock Recover (1.29.661.5). Happy OTA updating!

I've tried this, but the OTA update package won't install. Flashing the Recovery.img isn't enough.

I assume you're running a stock ROM, so did you delete any stock apps(i.e bloatware)? If so, you will need to NAND restore to a stock backup or get those apps back. First thing an official OTA does is check the signatures on all the files it'd expecting to be on the device and if any come back wrong or missing, update aborts.

So I was just wondering, if i install the bloatware/default apps back manually (using the .apk files) and flash the recovery back to stock. Will I be able to do an OTA update Without loss of data? If that´s possible, I wil flash the custom bootloader back after performing the OTA update.

Guys, thanks for helping me out. I've done an OTA update without any data loss, you can read about it in thishttp://forum.xda-developers.com/showthread.php?p=42122514#post42122514 Thread.

Flash stock recovery before proceeding
​.​
NOTE: If You are a rooted non-stock user I suggest you look at @rootSU's thread before proceeding as his method for rooted users is far less prone to cause issues.
http://forum.xda-developers.com/google-nexus-5/general/info-rooted-user-learn-to-update-t2927876
First, let's talk about what an OTA is:
An OTA (Over the Air) update is the method of updating your phone's software. When the OTA is downloaded to your phone it will prompt you to reboot and install. It is not a complete image, but a series of patches to the OS. Patches in the OTA can include: bootloader, radio, system, recovery and kernel. While it's installing, the script checks the files it is patching to make sure the original files are correct. If everything is correct, the update will finish successfully. If it's not, the process will stop. That's why it is critical to make sure everything is in its "out of the box" state. Don't worry though. It is easy to get your phone back to a state where you will have it up and running, with the latest software.
We are also able to manually flash this file. When the URL of the OTA is discovered, you can download it and use adb or a custom recovery to apply it.
Now that you have read the important info above, Let's update your Nexus 5!
In order for the OTA to apply successfully without intervention; you must be completely stock
From 4.4.4 KTU84P
Current Bootloader: HHZ11k
Current Radio M8974A-2.0.50.1.16
Stock Kernel: 3.4.0-gd59db4e
All /system apps present
No modifications to existing /system files of ANY kind.
From 4.4.3 KTU84M
Current Bootloader: HHZ11k
Current Radio:M8974A-2.0.50.1.13
Stock Kernel: 3.4.0-gd59db4e
All /system apps present
No modifications to existing /system files of ANY kind.
Note: Literally any modification will break the OTA. Xposed, DPI, build.prop, volume mod, etc. ANYTHING!
Seriously, I'm not joking guys.
If you meet the above criteria, the OTA will complete successfully.
If you don’t meet the criteria or don’t want to wait for the OTA to hit your device then see below.

These are the most common scenarios. If you aren't sure where you fit, feel free to ask.
NOTE: Starting with Android 5.0 (LRX21O) you MUST sideload the OTA in a STOCK RECOVERY. No exceptions.
Scenario #1
You are completely stock. Unlocked/locked bootloader. No root permissions.
Continue to Section A
Scenario #2
You are stock, with root. Custom Recovery without any modifications or deletions.
Continue to Section B
Scenario #3
You are stock, with Xposed Framework installed.
Continue to Section C
Scenario #4
You are stock, with a custom kernel and/or old radio and no other modifications.
Continue to Section D,1
Scenario #5
You are stock with any modifications to /system/ including removed system apk(s) and a custom kernel.
Continue to Section D,2 or See 2nd Post (Special Scenario #1) **Special Scenario #1 is not updated yet**
Scenario #6
You are running a Custom ROM
Continue to Section D,3
Section A: adb sideload
NOTE:Make sure you have the latest version of adb. It seems people are having issues with older versions. It's attached at the bottom of this. Also Starting with Android 5.0 you must sideload the OTA through a stock recovery. Custom recoveries for now will error out.
1) Download the OTA.zip on your PC, rename the file update.zip, then place file in the same directory as adb.
2) Make sure you have USB Debugging checking in the Developer Options, then connect your phone.
3) Open the command prompt from the directory above on your PC and type the command: 'adb reboot recovery'
4) When in recovery, you’ll see an android laying down. Press and hold POWER, and then press volume up and release. The menu will appear. Select “apply update from adb
5) Using the command prompt type: 'adb sideload update.zip' The file will load and the update will begin.
6) When completed, select reboot.
Section B: Flashing in a Custom Recovery (TWRP- CWM)
(For Flashing 4.4.4 OTAs and Below ONLY!)
1) Download the OTA.zip and copy to your phone.
2) Boot into recovery.
3) Flash the OTA just like you would a ROM.
4) Reboot.
Section C: Uninstalling Xposed Framework
Use the Xposed Framework Installer to remove the framework before applying the OTA.
Go into Xposed Framework, Framework-> Uninstall (it will restore the original file "app_process") then reboot.
NOTE: If you just uninstall Xposed Framework (the app itself), even after a reboot the "app_process" file (in /system/bin) is still the modified one by Xposed Framework, the original file is not restored.
Xposed Installer and info can be found here.
Once Xposed is uninstalled; jump back up to Section A on stock recovery (5.0 and above) and Section B on custom recovery (4.4.4 and below).
Thanks @Hammer_Of_The_Gods & @C3C076
Section D: Let’s get back to stock
1) Flash the stock boot.img and/or radio.img (whatever is applicable) from the factory image using fastboot. Also flash recovery.img if updating to 5.0
Fastboot commands used in this section would be:
Code:
fastboot flash boot boot.img
fastboot flash radio radio-hammerhead-M8974A-1.0.25.0.23.img
fastboot flash recovery recovery.img
NOTE: Some custom kernels will modify files in /system/ If this is the case you will see a status 7 error and the file modified. The easiest way to fix this is to flash the system.img
2) Replace the stock kernel or .apk(s) you removed or modified.
If you don't have a backup of removed or modified apk(s) flash the system.img
Note: These must be the exact versions that shipped with the rom.
Fastboot commands used in this section would be:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
3) Flash the KOT49H stock image. Follow abaaaabbbb63's guide if you need help.
--------------------------------------------------------------------------------------------------------------------
After completing the steps needed to return to “stock” make sure you meet all the criteria at the top of the page then revert to:
Section A if you are running stock recovery.
Section B if you are running a custom recovery (for 4.4.4 OTAs and below only).
Feel free to ask any questions you may have. I’ll do my best to answer them as quickly as possible. Perhaps others may answer them as well. Please read to see if your question has been answered before asking.
FAQ
Q: When in Recovery/Bootloader the phone isn't listed in Windows Device Manager.
A: Uninstall all current N5 drivers and install the Universal Naked driver. Turn on USB Debugging in Developer Settings and boot to recovery
Q: I'm seeing a status 7 error when trying to install the OTA
A: Look at the error closely. It will describe on the file it is failing at. Post the file path so we can help resolve the issue.
Q: The ota applied successfully but I lost my custom recovery and I want to re-root. How do I get root back?
A: Flash the custom recovery of your choice in fastboot and use it to regain root permissions
Q: I've tried everything, but I'm still getting status 7 errors.
A: Unfortunately you may have to start from scratch. Follow Section C1.
Q: I flashed a .zip file that modified (insert mod here.) Will I the OTA install successfully?
A: No, any modification at all will cause the OTA to fail.
Q: Why do I get a "cannot read update.zip" error when trying to sideload?
A: If you named the file update.zip, the actual name would be update.zip.zip. Windows auto names extensions by default. That could be your problem. If not try another usb cable or a different usb port. If that still doesn't work, make sure you type exactly what you renamed the file. You may have made a typo. It is also case-sensitive.

Scenario #2: Will I receive a message ?
Thanks for this thread. It's just what I've been trying to figure out.
So, if I'm Scenario #2, will I received a message on the phone when the OTA is available? Can I let it download then install through TWRP ?
If I'm reading correctly, the custom recovery will not let it install automatically (and maybe I don't want it to since it could wipe out TWRP). On reboot will TWRP prompt me to root the phone (that's how I got to root the first time).

If you're rooted, but with stock ROM, do you know for sure OTA updates won't go through? Thanks.

I believe the new versions of recovery will ask to keep the custom recovery and/or root. We'll see how the custom recoveries handle the OTA on the N5 and I'll update the post accordingly.

It all depends on how you gained root access. If you used cf-super boot it will not go through because it modifies the kernel.

What about cf auto root? From the description it looks like that only adds the root apps and nothing else.

Cf-auto root and super su should be fine as they don't modify the kernel.

Hi I would just like to confirm if the Nexus 5 is like my old HTC One in that I would receive OTA updates on a stock rom and stock recovery with a unlocked bootloader.

As long as everything is stock an unlocked bootloader does not effect an OTA.

Scenario #3
You are stock, with custom kernel, any modifications or removed system apk(s)
Continue to Section C
Scenario #4
You are running a Custom ROM
Continue to Section C
Section C: Let’s get back to stock
You have two options to do this:
Option #1 Flash the KRT16M stock image. Follow @abaaaabbbb63 guide if you need help.
If you want to keep data intact flash only the boot.img, system.img, and recovery.img (optional)
OR
Option #2 Replace the stock images or .apk(s) you removed or modified.
Note: These must be the exact versions that shipped with the rom.

Just to be sure, flashing only boot.img and system.img will keep my apps and all user data, correct? I can live without the center clock mod and battery % for now.

I tried searching for network as well but that didn't work either. The wifi works, but no network.
I restored a backup I made last night and it still isn't working. Any ideas?
Tried to do a system wipe then restore again

[Q] How to upgrade bootloader to 10.26.1.18 ?

Hi,
I bought today a 701T ww, with bootloader version 10.26.1.7.
I've been able to unlock the bootloader, root the rom, and install a custom CWM (now 6.0.4.6).
I installed the custom rom CROMi-X 6.0b2
But I'm now unable to upgrade the bootloader to 10.26.1.18.
I reverted to stock 10.27.1.7 rom thanks to the nandroid backup I made prior CROM install, I've tried downloading the official update package from Asus, which is supposed to be the only way to upgrade the bootloader. I've put the UL-K00C-WW-10.26.1.18-user.zip file on the root of a MicroSD, the tablet recognized the update file, and rebooted to install it. Problem is that, after reboot, the tablet enters in the CWM with the following error :
{
"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_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Off course if I try "Yes - install untrusted.zip" it doesn't rework, and the tablet reboots ....
many thanks if you can help !

Turn off "signature verification" in CWM and try again
BTW: How did you miss this??????
TF701T USERS: YOU MUST BE UNLOCKED, ON THE ASUS STOCK JB 4.3 BOOTLOADER VERSION 10.26.1.18 AND HAVE A WORKING RECOVERY - CWM 6.0.4.6+ BEFORE FLASHING THIS ROM. SEE UPGRADE INSTRUCTIONS BELOW IF YOU ARE UNSURE[/SIZE]

Hi Berndblb, thanks for your reply.
Toggling the signature verification didn't help, I've already tried that.
I didn't miss this, but as I've never been able to upgrade the bootloader thanks to the official update, I thought that with CROMI the bootloader would be upgraded too. I noticed that was'nt the case, that's why I restored my nandroid backup to revert to the stock 10.26.1.7.
Now I'm in 10.26.1.7, and precisely want to upgrade the bootloader to be able to install CROMI with the correct bootloader. Therefore my question.
Would a "fastboot flash boot boot.img" using the boot.img file included in the official asus 10.28.1.18 package be a good idea ?

Okay, I finally solved it ... Here's what I did :
I downloaded the stock recovery from this url : http://droidbasement.com/db-blog/?p=3210
I booted on this recovery (fastboot boot recovery.img), and the upgrade could be completed.
I'm now under stock 10.26.1.18, with corresponding bootloader :good:

Hey man! Thanks for the explanation. I seem to have a similar problem as you had and tried to use your steps to fix it.
However, when I boot into the stock recovery the green android figure appears and falls on the back (with exclamation mark) after about 2 seconds... Is there something else to take care of, any ideas what I might have missed?

That is great news! The Android on his back is the stock recovery not finding a valid update file.
Download the .18 firmware again (remember - you edited the update script) and you should be good to go

Wow! I hope you're right.
Will I need the original WW_epaduser_10_26_1_18_UpdateLauncher.zip or the once unzipped UL-K00C-WW-10.26.1.18-user.zip - and what about the WW_10_26_1_18_SDupdate.zip? Where do I have to place them, on internal storage or fat32 formatted microsd card? Thanks in advance!

Copy the xxx.18-user.zip to the root of your internal, meaning not into any folder, just into /sdcard.
A notification to upgrade should pop up. If not, reboot.
The SDupdate.zip is only available for the WW version and I suspect Asus provided it because a few weeks back they pushed a bad update to WW users, causing their tablets to hang in boot. I suspect it's specifically meant to be used to update from the microSD in your recovery (if you cannot boot system), but that's just a guess.
So if method one doesn't work, copy the SDupdate file to a microSD, boot into stock recovery and it should recognize the file and flash it.

It did indeed start installing the update just as you said it but after 30 % or so an error errupted and the android guy fell over again. I booted the tablet and received "error no 12 - the update package is not compatible with your current software. please check your software version and number in the settings and use the right update package."
I did use the UL-K00C-WW-10.26.1.18-user.zip which is for WW SKU, and the build number in the settings says:
JSS15J.WW-epad-10.26.1.7-20131108
The method with SDUpdate file doesn't work either. It doesn't recognize it in the bootloader (as explained in the official info document from asus) and when I boot into recovery manually the installation fails after a second or so.
I'm really sorry for bothering that much, but do you know what's my fault?
Update: I just kept on trying and with the fourth try it did work! It did update to .v18, now the build number in settings AND the bootloader confirms it. THANK YOU SO MUCH, everyone @ berndblb, usoska, super0dd, Sleepy2 and sbdags! I'm in your all's debt.
So I will now flash
- this recovery : http://droidbasement.com/db-blog/?p=3223
Once this is done,
- I finally flash the CROMi-X ROM with the just installed CWM 6.0.4.6
Is that correct or did I miss anything?
I am so thankful, guys!

WooHoo! excelent. Glad you got everything all sorted out.

Guys I've tried for 2 days to make a flashable zip to flash the latest bootloader and recovery but the tools asus provided only appear to work with the stock recovery. CWM currently does not support this method and I'm giving up at the risk of bricking.
So the method for now is the one posted above:
Fastboot flash the asus stock recovery.img and then update to the latest firmware then fastboot flash the latest CWM.

How can I tell which bootloader (BL) and firmware (FW) I run currently? When I hold power/volume down, the top of the screen says user BL released by "US_epad-10.26.1.7". When I boot into Android and go into settings -> about -> software, I see Build number "JSS15J.US_epad-10.26.1.18". Is the 1.18 the firmware (FW) version?
Finally, is there a way to upgrade BL/FW to ...1.18 version without using an external SD card?

US_epad-10.26.1.7 is your BL version
JSS15J.US_epad-10.26.1.18 is your OS version.
Currently the only way to updated the BL is from the SD card

Thanks. Just to verify, you don't think doing "fastboot flash boot boot.img" will work? (using boot.img from UL-K00C-US-10.26.1.18-user.zip).
Also, by SD-card method, are you talking about the rename “WW_10_26_1_18_SDupdate” to “T4_SDUPDATE.zip" process etc.? It seems that I have the US SKU, and not sure if this would work, being that it mentions WW in the file name.

I am no expert but I am pretty sure that the fastboot method doesn't work as there have been several people with the wrong bootloader issue and and the only way to do it was with the official update.
I am not sure about using the WW file or not. I am in canada and I used the other file to update and that did the bootloader also. With the status your in now I am not sure if the US one will work or not. I would try the US one first and then if not go with the steps from pershoot

[RESOLVED] Bricked after flashing firmware for Pie, stuck in md5 checksum bootloop

Hello,
I post here after 12 hours of continuous search and attempts at fixing things on my own, which may have dug me deeper into trouble than if I've asked for a tailored solution to this issue. Apologies for repetitiveness if I've failed to find answers elsewhere.
I was running LOS 15.1 with custom kernel and maybe the 5.0.8 firmware or lower. I don't recall the version.
In an attempt to flash LOS 16.0, I performed a nandroid backup, but didn't back up my internal storage. That was stupid of me
I grabbed all the files needed, and started by flashing the firmware version stated in the flashing guide for LOS 16., which was 9 point something.
Phone bricked, blank screen.
Got hold of a factory reset tool from an unbrick guide here, followed their steps to completion despite repeated failures in the MSMDownloader.
Now my phone boots in fastboot mode only, adb on PC neither can detect nor interact with the phone, and it is stuck in a md5 checksum bootloop with "modem" and "dsp" in the red, and all attempts to boot into recovery lead back to the md5 checksum screen.
On fastboot mode, "Bootloader version" and "baseband version" are both blank.
This is all I know to provide at the moment. If there is any way to salvage the phone with the internal storage intact, I would prefer that please. But I won't look a gift horse in the mouth at this point if I ultimately have to wipe everything clean to fix the phone.

bump pls
even bad news is appreciated

Thank you for answering.
Fastboot can see and use the device. Flashing is possible through it.
ADB cannot. I'm not sure if it's the latest version on my PC, but I recently had the phone connected to a different PC with a recent ADB installation and the results were the same. ADB doesn't see the phone.

Hmm.. does phone in TWRP works like USB storage?

Phone fails to boot into recovery.
I flashed TWRP but it always boots into the failed md5 checksum anyway.
Recovery doesn't work.

Worth noting is that TWRP flashing causes the recovery: ok message to also read as recovery:failed.
Flashing the stock recovery that came with the unbrick tool using fastboot makes it recovery: ok

It won't boot into any recovery, stock or otherwise. Only brings up the screen pictured above.
EDIT: By "stock recovery" I mean whatever the unbrick tool had flashed into the phone using the MSMDownloader utility.
The version of OOS included in the tool is mentioned as 3.2 or some dated system. Maybe a more recent recovery might work?
I can't find a standalone, recent stock recovery image. I'd flash one if I found it.

Fastboot and adb will never work at the same time, by definition. If Fastboot works, you are in fastboot mode. adb only works in OS or alternately in TWRP, and will never work in fastboot mode.

I forgot a detail in the middle of the story.
Right after I flashed the pie firmware, it restarted and I was given a prompt that said something along the lines of "Flash successful and everything, but decryption failed. You will lose all data if you boot, are you sure?"
I turned off the phone, from there it bricked with a blank screen. It was then that I got the unbrick tool and went through the rest of the earlier story.

I got past the MD5 checksum hurdle, and I flashed TWRP. It works.
I can't access internal storage to flash anything from the phone, not even the TWRP nandroid backup, but ADB is an option again.
Decryption refuses to take my password even though it's correct.
I do have a backup of the nandroid on my PC. Could I flash that via ADB?

If you can get into TWRP I would suggest you use the latest version 3.3.1-0 and use wipe>format data (not wipe>advanced wipe) which will clear the encryption. It will give you an ext4 data partition, which is fine. If you want to change it back to f2fs use wipe>advanced wipe to reformat it to f2fs.
I don't recommend using an unencrypted phone so my next step is to copy from your PC to the phone the ROM zip file and anything else you need to flash. I would flash the full OOS zip and let it boot up as this will automatically encrypt your data. It will also replace TWRP with the stock recovery but you can flash TWRP again using fastboot. You can then go back to TWRP and set things up the way you want, including restoring the backup you have.

Thank you for dropping by.
Regarding the couple of errors in the MD5 checksum, "modem" and "dsp", the problem lied in that I didn't know which files I'm supposed to flash using fastboot to fill their spots.
By referring to the forum post of the firmware here, I found one workaround was to "consult META-INF/com/google/android/updater-script in the flashable zip of the firmware ... to check which file from the firmware-update directory goes to which partition."
From there, I inferred that "modem" takes the file named NON-HLOS.bin, and that "dsp" takes adspso.bin
Flashed them via fastboot, and I was greeted by a successful boot to stock OOS 3.1.2, the version provided by the unbrick tool I used.
However, it seems that the damage done to the phone (either by the failed firmware flash or the unbrick tool) has led to the internal storage being corrupted, or perhaps the damage was done to how the system decrypts internal storage. I am a medical student, so most of these intricacies are way out of my league.
I was hoping to recover the internal storage, but would gladly part with the data if it means I can use the phone again. There was nothing particularly important on the phone that the TWRP backup didn't have.

Pardon me, but which file system would be most suitable for each partition?
The Wipe>Advanced Wipe menu offers several file systems for several partitions. I'm inclined to leave everything as it is, but should I perhaps format the /system partition as f2fs for instance?
