[Q] Can't unbrick. Tried nigh everything.

Greetings! First of all, I would like to thank anyone who takes the time to help me diagnose and resolve this issues, let alone anyone who takes the time to read this thread.
I've been having issues with my Xoom (ICS 4.0.0) for about 3 weeks now.
A brief history of the issue's occurrence:
-I unrooted the device and returned it to stock.
-Everything was fine and dandy until one day it spontaneously said something along the lines of 'Android is upgrading..', and then performed a reset.
-Since resetting, it bootloops.
The device only turns on when plugged into a charger and hard reset.
The device only turns off when allowed to boot loop for minutes and then hard reset (it simply does not reset, and just turns off).
I'm not the most technically-savvy person with android devices but here are some things I've done/noted.
When trying to use adb commands, it does not recognize the device or properly issue commands.
I've tried wiping data/clearing cache to no avail.
EDIT: I've tried fastbooting, but the bootloader will not unlock. When trying to unlock, it simply resets and then acts as though it was never unlocked.
I have no idea how to return it to a stock image. All I know is that I have a micro-SD and some spare time.
Could anyone help me understand what exactly is going on with my Xoom?
If I can provide you with any more information, please let me know.
Thanks again. (=

If it was stock and spontaneously upgraded it sounds like a bad OTA upgrade. I've been rooted from the start so never have taken an OTA upgrade...don't you need to accept it or can it just upgrade on it's own?
Anyway, can you get it into fastboot mode?
Volume up and power, then at dual core screen, press volume down...if you see something like "entering fastboot mode" you're not bricked. You do not have to re lock your bootloader. Just make sure you have downloaded the correct stock files for your Xoom model to your PC and flash it.
If you haven't done so, just google 'recovering Xoom using fastboot' and you should get some good information.
Good luck!

Remember to grab the MZ604 files if you have the Wifi only version of the Xoom.
http://developer.motorola.com/products/software/ <------ Grab the files here. The files are for the US version of the Wifi Xoom only.
Instructions to return it to stock
1) First you need the Moto Drivers - Read this thread to START you - http://forum.xda-developers.com/showthread.php?t=981578
Should have these drivers installed if you have rooted your Xoom before.
2) Make sure you have the latest SDK - adb and fastboot should be in /platform-tools -
http://developer.android.com/sdk/index.html
Should have the android SDK if you have rooted your Xoom before.
3) Place all the downloaded stock image files into the SDK Tools folder.
4) If you are booting up from scratch, you can get the Xoom in fastboot mode by doing the following. Use command prompt to perform the rest of the steps
Hold VolDown and Power button will boot unit for fastboot mode
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
If you Xoom is booted up already follow the commands below using command prompt to perform the steps
adb reboot bootloader <---- reboots the Xoom into fastboot mode.
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock

When I try to execute fastboot commands such as 'fastboot flash boot boot.img'.. it says the following:
Device still locked. Device must be unlocked first. Failed to process command error(0x8)
Whenever I try to unlock the bootloader, it appears to be successful at first and then the device reboots. But it just reboots to a bootloop, and the bootloader still says its locked. Perhaps I made a mistake in communication. The bootloader is currently locked and will not unlock, as just described.
When I try to unlock it and it reboots, even if I access the fastboot menu right away, it still says the device is still locked.
Thoughts?

Can you get into recovery? With the Xoom off (to make sure it's really off, hold volume up + power for a few seconds), hit the power button and when you see the M logo, wait a very brief moment (like a fraction of a second) and hit the volume down button. When it says "recovery" on the top left, hit the volume up. If you can get in there, either restore a nandroid (if you have one) or do a factory reset.

Yes, I can get into android recovery. However, within a second of switching into recovery mode, the robot falls down and there appears to be a red triangle caution sign containing an exclamation point.
When trying to do a factory reset, it says all data is wiped (as normal). Upon rebooting, it continues to bootloop. So essentially the factory reset and cache clear options in the Android Recovery menu do not produce the expected results.
Pretty odd. I didn't mess with the Xoom at all prior to this issue.

Try flashing just a recovery img to hopefully get your recovery working again. I think you can flash a custom recovery even if the bootloader is locked (i could be wrong but worth a shot) I attached the Rogue "recovery-rogue-1.3.0.img". Try a "fastboot flash recovery recovery-rogue-1.3.0.img"
EDIT: Sorry, I guess you can't flash a custom recovery with a locked bootloader.

Yeah, just tried it to no avail. Thanks so much for your help anyway. (=
I'm not sure what to do now.

I would keep trying to unlock it using different USB cables and different USB ports on your computer. I've had unlocks fail a bunch of times and for some reason, it was because of a $hity USB cable and/or a bad port on my computer.

I hear ya. I've tried 2 different cords and 3 different computers. I'm using a Mac (10.6.8) right now, but have used 2 PCs (Vista + 7).

Out of curiosity, when you tried to flash the custom recovery, did you get the same "device still locked" error or did it appear to flash but then recovery failed?

I got the 'device still locked' error. Weird, huh?

How about trying to lock it again even though it says it's locked -maybe it's stuck in an "in-between state"? Try a "fastboot oem lock" and if it finishes then try a "fastboot oem unlock". I know, I'm grabbing at straws here. I thought I bricked my Xoom last week. All I did was an "adb reboot bootloader" and the device went to a black screen. Volume Up + Power did nothing. I ended up buying a T5 (Torx 5) bit at the store, removed the back cover and disconnected the battery for 30 seconds using a piece of paper to separate the contacts. The Xoom booted right up after that.

Yeah I tried that. Won't lock or unlock successfully. Locking produces no difference, and unlocking produces the same 'device still locked' error. This is getting out of hand! Thanks so much for your advice. You think I should open it up?

I hate to be so persistently annoying about this, but could anyone possibly suggest a method of working around the locked bootloader?
Is there anything I can do with an SD card to remedy the device's stubborn foolery?

I think you should give it a try, I have bricked my xoom a few times and have always been able to flash the stock imagine to recover. You really have nothing to lose by pulling the battery pin just be careful.

I don't know if I'm technically-equipped enough to do that. )=
Sounds easy, but I imagine it would be rather easy to screw something up? Essentially what I should do is unseat the battery, right?

[Q] flashed to 4.04, bricked phone

A long time ago I rooted my phone and put CM9 on it. I decided I wanted to go back and try Jelly Bean (from factory then go outwards).
I had a difficult time with the CM flash and found one that worked, and thought I was good to go.
My phone: gt-i9020a nexus s
Product name: Herring
HW version 16
boot loader: i 9020xxkl
carrier att
fastboot enabled
unlocked state.
I can launch the official 2.3.6 (Build GRK39F), from google
then the OTA updated kicks in and the phone is stuck at 'boot' Google logo on the screen.
I have done the information below and the same keeps happening...
link: http://forum.xda-developers.com/showthread.php?t=1586845
first of all, the VQ8PQk is a patch file, not a full rom. So flashing that on something else than 2.3.6 will never work. Get into clockworkmod recovery wipe wverything from the mounts and storage menu, and then flash this file : http://android.clients.google.com/pa...o/ZD3PyN0t.zip and THEN this : http://android.clients.google.com/pa...o/hR7QFEtn.zip
and other steps I could try to work around, none of them seem to work.
Am I missing anything?
Thanks!

Use the full factory rom images (sojuaxxxx) from Google.
https://developers.google.com/android/nexus/images#sojua
Follow the instruction on that page (scroll up). If using Windows, use 7zip (or similar util) to expand the .tgz file, open content of "flashall.sh" and execute the commands one at a time.
Code:
fastboot flash bootloader bootloader-crespo-i9020xxlc2.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020uckj1.img
fastboot reboot-bootloader
fastboot -w update image-sojua-jro03e.zip
The last command will wipe all data and install new 4.1.1 rom.
Edit: install CYGWIN to have linux-like commands (works with tar, adb, fastboot) in windows.

Do you have a backup (preferrably CWM backup) that you have prior to trying to get JB working? If so keep that handy, and preferrably store it on the PC. Titanium backup can ease migrating apps after a wipe and is highly recommended, so do one of these too if you havn't already.
After you make sure you have a solid backup with the information that you want/need on the phone, i would just start fresh. The best way to do this is to do a factory image flash (note: you want sojua if you have the 850MHz variant which is from AT&T). Flashing these will wipe all user data and the /system partition, the sdcard won't be touched. Basically you download it, extract it, then hook up your phone in fastboot mode and do the commands as written in the text file (or run it as a script if you know how). I've described it in more detail elsewhere as have others, doing a search should give results pretty quickly
This will become a factory install of android as given by google, in your chosen version. I'd go straight ot JB and then you can see how much you like it. CWM backup data can be extracted if you lost some crucial information in the flashing and all your apps and their data can be easily restored with titanium backup.

running linux, no cygwin needed
did this again this morning..and i'm stuck on the google boot screen with the unlocked padlock on the bottom.
how long should this run (20 minutes now)
I have tried the roms from that page, the 2.3.6 is the only rom that I was able to get working..

Make sure you use the sojua versions.
Do you mean you finish all the steps and upon reboot, it's stuck on Google boot screen?
What do you mean by you can only get 2.3.6 working? It went past Google boot screen?

** ran 'flash-all.sh" see if that changes anything, nothing like a script to rule out human error.***
**** that was a mistake...now phone is not turning on, the screen is dead...when i plug in USB chord, nothing is detected no state change on the phone. When I press buttons no state change nothing changes on the screen. I actually think my phone is a true brick, not a software glitch that is fixable....any suggestions now? ****

Some (quite a few) Nexus S seemed to be vulnerable to Jelly Bean/CM10 update in that the mainboard is toast. I think the only option is to send back for warranty repair. There are some threads on rigging some kind of adapter cable but that will definitely void your warranty (physical mod).

Doesn't sound good, there have been instances where the flash storage has given up and ends up needing a new SoC (the whole mainboard) and similar issues. Some more information would be good to diagnose this better though.
-Take the battery out for 5 minutes, place back in, can you get into fastboot?
-Can you flash recovery and radio? Can you enter recovery?
-After the "fastboot -w update ...." command, what messages do you see on the phone (at the bottom)?
If you can't get the phone to turn on at all after a good 5 minutes without the battery inserted, give AdamOutlers resurrector a shot. A nice phone call to samsung might be a good idea if you're still within 12 months of purchasing. Hopefully it all turns out okay.

Did all of the above, nothing. adamoutliers does not see a device connected.
lsusb shows nothing
dmesg shows my device disconnect, after the failed boot, no reconnect.
I'm headed out for a few hours, I will leave battery out, and phone disconnected but i'm thinking it's toast. Att will send an RMA phone to me, they gave me a choice of samsung focus (I asked how a windows phone was similar to an android?) or a samsung galaxcy II skyrocket...I'll try samsung next..
Thanks for all the help!

Problem after unlocking bootloader - Bricked?

Hey guys, how are you?
Well, I wished to root my Moto G, so I (tryed?) to unlock the bootloader. Alright, done it, but then I ran into some trouble...
After the booting up, everything started forceclosing and since then, when I try to boot it, I get a black screen after the Motorola logo.
Now, I am really really worried about my phone. I got it a month ago. I'm so afraid I really f****d up my phone right now that my hands are shaking.
I'm new to Android, so sorry if the solution is pretty obvious. And if it's not, could explain it very carefully to me? I don't know what to do.
My best wishes to you, guys.

I'm assuming you used superboot if so that would happen.
The logo sort of blured out right just press volume down and power and it would work
Or did this happen when you were just trying to unlock bootloader?

Yeah, that happenned when I was trying to unlcok bootloader.
And well, my computer now doesn't even recognizes my phone.
EDIT: It appears as "Fastboot falcon S" in the Device Manager. Tried installing some drivers I found in the Internet, but it didn't work.

Explain exactly what happened please. Was the unlock successful and did you just bootup normally after or did u do anything else in fastboot mode? Why are you trying to install fastboot drivers again, as you already wouldve had them to unlock the bootloader. Did you try installing recovery or some root img from fastboot? You said its forceclosing, but it isnt starting at all now?
Some things you can do right now (if your bootloader is unlocked) is to flash a recovery (twrp,cwm) through fastboot and if you think most system files (or settings) are beyond repair, flash your firmware version though fastboot. Will point you to the guides for them, but post more info if you want help.

Alright, just after I unlocked, when I was booting, I got a message saying that "xxxx has stopped working/failed to initialize/something like that". And then, when I rebooted, I got the usual message of the "bootlocker has been unlocked". After that, the Motorola logo started animating, but then I just got a black screen. I can't turn it off and the battery just got depleted (I'm charging right now).
When I try to connect it in my computer, the PC recognizes it as "MTP Device" or "Fastboot falcon S" when fastbooted. I can't install any drivers and the Motorola Device Manager doesn't recognizes it either.
Well, if there is some missing information, just ask me. I tried to describe my problem the best I could. Anyway, sorry for my bad English and thanks in advance for any effort trying to discover what's wrong.

Motorola Device Manager isn't helpful in this state as it doesn't handle things in fastboot. You already have all the required drivers (fastboot falcon S is the right driver afaik, falcon being motog codename) for flashing your stock firmware.
1. First, you can try the "Factory" option in bootloader (the third one, use volume down to move selector, volume up to select), though this might not really work for major issues.
2. When in fastboot mode, use "fastboot getvar all" to get the firmware details if you already didn't know about it.
3. Otherwise if yours is a standard gsm (non dualsim/non cdma), just download Blur_Version.174.44.9.falcon_umts.Retail.en.GB (UK stock for gsm, 4.4.2)
Download the mfastboot files to use rather than fastboot for flashing. You might need to modify your commands a bit for various firmwares.
http://forum.xda-developers.com/showthread.php?p=47820707 (refer this thread for flashing your stock firmware)
All the firmwares are in either of the links below (all around 400mb):

I still don't get why many ppl are getting these errors after unlocking, very bad unlock method of moto if so ( I didnt get any such issues though).

When I use the "fastboot getvar all" command, it says "waiting for device". The phone is already connected, but the Moto G doesn't recognizes it's connected either.
I'm getting more and more afraid I really hardbricked it.

Tried installing these drivers? Your fastboot doesn't seem to be setup properly. How did you unlock without a working fastboot driver? You are trying that command in bootloader mode right?

Already installed it from the start. The message I got is always this:
"There aren't any updates for your device at the moment
Current Version: N/A"
My fastboot: Doesn't matter the operation I do, I always get this <waiting for device> and the phone is already connected into the computer. And the phone doesn't recognizes it is connected too.
And greeeeat news: my phone now doesn't charges either. I get stuck on a screen with a battery logo and 0%, when connected to the charger. Still, I still can access the fastboot mode. Well, am I lucky or not?

I'm pretty confused with this. How exactly did you unlock without a working fastboot (no waiting for device issue)? Did you change your pc drivers after unlock or trying this from a different pc? When you say "phone doesn't recognizes it is connected" you mean it says "Connect USB data cable" below "Device is UNLOCKED"? If so, maybe try another usb port cause it should normally say "Transfer Mode: USB Connected" regardless of proper drivers.
Your phone will chrarge no matter what though, no worry about that. It needs to say "Battery OK (Charging)" when connected to PC
No, as long as you have working your device isn't technically bricked in any sense. Don't worry, get that fastboot working again and anything can be fixed.
Also you didnt say whether or not you tried that "Factory" option in bootloader!

Guys the problem occurs due to corruption of /data folder. Even I had the same issue.
What you can do is
1. Connect your phone to PC in fastboot mode.
2. In fastboot, enter the command "adb erase userdata" and "adb erase cache" without quotes and reboot you phone. It will work for most of the devices, if it doesn't I have some other workaround too.

Give a try to factory reset from fastboot mode on your phone. And do you a custom recovery installed in your phone?

Hello.
I did something wrong while trying to flash TWRP on my pixel 2, I am now stuck at the bootloader, and I cannot boot System or Recovery. While at the bootloader screen, it says Device State : unlocked. If I try to get to download mode, it says "ERROR: Operation Denied". If I try to go into recovery, it says "ERROR: Slot Unbootable: Load Error". If I try "Start", I get the same error message.
Also, adb or fastboot don't seem to be able to "see" the pixel connected to the computer. I believe my cables are good since I was able to flash Magisk and reflash the whole system with them before bricking it.
Can anyone help?
Thanks!

Just as a reference for anyone else who needs the fix and can't be bothered opening another thread.
SOLUTION: At the menu where it is stuck and saying device fail etc, plug in your usb cable to the mobile, press and hold the POWER button for 10 seconds, it will now recognise your phone under fastboot.
Once that is cleared, it's pretty much straightforward flashing latest pixel 2 image via fastboot and problem solved.
sidenote: Issue came with anyone who tried to flash december security updates and above as of what I heard.

I will try that, thanks.

So, several things :
Holding down the power button had no effect other than restarting the boot menu, but Fastboot never became available.
Opening up the phone and disconnecting the battery and reconnecting it made Fastboot available again. This would be in line with other users that let the phone battery discharge completely before regaining fastboot access.
Sidenote : opening up this phone is not for the faint of heart. I managed to damage something on the motherboard doing so (probably a static electricity discharge), the screen ended up displaying gibberish. I was able to salvage my phone by replacing the motherboard. I had ordered a replacement motherboard when I thought all was lost with no fastboot, and I had it on hand. Expensive little sucker...

Hello.
I did something wrong while trying to flash TWRP on my pixel 2, I am now stuck at the bootloader, and I cannot boot System or Recovery. While at the bootloader screen, it says Device State : unlocked. If I try to get to download mode, it says "ERROR: Operation Denied". If I try to go into recovery, it says "ERROR: Slot Unbootable: Load Error". If I try "Start", I get the same error message.
Also, adb or fastboot don't seem to be able to "see" the pixel connected to the computer. I believe my cables are good since I was able to flash Magisk and reflash the whole system with them before bricking it.
Can anyone help?
Thanks!

Same thing happened to me except I never even tried to root. Just pulled the phone out of my pocket, and the little Android dude was belly up. It's showing device locked - and although I had it in Dev. mode from weeks back (thought USB Debugging was enabled) it fails to respond to adb commands, boot-loader mode, etc.
...Looks like Google laid an egg with this one.

Pixel 2 - "ERROR: Slot Unbootable: Load Error"
If you get the above error you will find that you cannot boot into recovery and the phone stays in the bootloader screen each time you try to start the phone. If your bootloader is unlocked you might be able to recover your phone to flash a stock image and revive. My problem started when I tried to restore a nandroid backup after trying out Android Q beta 1. I got the error mentioned above.
Most of the people recommended that I get a replacement from Google support as they had tried everything but it didn't work. Well right here in XDA Pixel 2 forum there is a solution waiting to be used. I am reproducing it from the post titled
"December factory image seems to have broken fastboot enumeration"

A possible way to resurrect a bricked Pixel 2...
Hey guys, I have just been able to get mine alive. The device started to be recognized (USB/fastboot) after about 10 unsuccessful attempts to start the system: "Start", from bootloader.
So what exactly happened and what I did:
1. Bricked a Pixel 2.
2. It started into bootloader and showed the "slot unbootable" error.
3. The device was not recognized by any of my machines at all, lsusb did not show anything new in the system, and, respectively, fastboot did not see the device.
4. The default option in the bootloader is "Start" if I remember correctly. So I just pressed the power button and did not release it until I noticed a vibration. It were about 10 unsuccessful attempts of system loading before that vibration.
5. Right after that vibration I connected a generic (NONAME) USB-C <-> USB-A cable to both the device and my Linux machine, and fortunately the device was recognized by the system and fastboot was able to detect the device correctly. So I flashed the a factory image, and it went just fine.
Unquote
Let me confirm that this works. I kept the power button down while the phone was connected via USB to the PC for at least 5 mins. During several reboots suddenly I got a beep from the PC which indicated that ADB was working. I flashed a stock image and voila the pixel 2 is back in operation.
Hope this helps several other people who might have this problem.

I don't even know how to thank you. I almost had a heart attack watching my Pixel bricked. Thanks man!

Save my day! I just keep pressing power button and fastboot response finally!

Can this be done if the device is locked?

If the boot loader is locked look for a script for unlocking the bootloader from recovery or bootloader state. I did find it but cannot remember. My bootloader was unlocked so I did not have to use it.

OP7 Pro Fastboot Bootloop! [HELP]

This may be a simple solution, but I am completely puzzled on how to fix this.
SO i recently rooted my phone & used the twrp "twrp-3.3.1-4-guacamole". Installed magisk via that twrp and continued with my day.
I accidentally got a virus by trying to get a full free vpn, me being a terrible pirate, i accidentally got a virus! Silly me.
It was annoying me and I decided to factory reset my phone... not via twrp. I remembered after I clicked "Reset all" on oxygenos that it's not the way how to do it with a root device, and well.. it didn't exactly work.
Every time I power/reboot the phone it just brings me to the fastboot menu of "START", "POWER OFF", "RECOVERY MODE", & "RESTART BOOT LOADER". I thought since TWP is recovery mode I try to access that... no luck, it just brings me back to that fastboot menu. I tried going on CMD via adb by saying "fastboot flash boot twrp-3.3.1-4-guacamole.img". It will say it's finished and successful, but when i reboot and try to access recovery mode it just does not work.
TL;DR: Think I bricked my phone, there is no OS installed and I can only access the fastboot.
Any help? Much appreciated

Thank you for the guap recovery as i didn't know it existed. However, what are the steps? when i go on the MSM download tool it doesn't detect my phone.
that being said, i can't access any of my files through my pc using fast boot. on MSM it's just saying "waiting for device" even when plugged in so thats annoying.

I downloaded the one you sent, and after a while as my internet is bad. It still does not work.
Whenever I try to install the qualcomm drivers it never shows up, and when i try and boot it up so the gual recover detects my phone it never works. It's still saying "waiting for device".
Does anyone know how to fix this? it's doing my head in that it's not as easy as it should be.

Pretty sure that your phone will not be accessible via adb/fastboot during the msm process. Did you follow the directions in the link above to a T?
A few things to note:
- Works perfectly fine for unbricking GM1917 modeled OnePlus 7 Pros.
- Use the original cable and try to plug it into a USB 2.0 port. I've found that this is the most ideal condition.
- Make sure your device is charged up. If you can't see how much charge it has, leave it charged via the 30W warp charger for 40 minutes and that should be good enough.
- In the L2 drivers folder found in the archive, navigate to the 32 or 64 folder depending on your system's architecture, and click on the file that ends in the extension ".cat". Then, click "view signature", then "View certificate", then "Install." This is IMPORTANT.
- Then, make sure your device is powered OFF, then, plug in the USB-A side of the cable (big head) into your computer and do NOT connect the USB-C (small head) into your phone yet.
- Hold down Volume up AND volume down for five seconds, and while you're continuing to hold, plug the USB-C side into your phone. The drivers should automatically download, and you should see a "Qualcomm QD loader" device in Device Manager. If you see an exclamation mark or you don't see this, you are doing it wrong and you need to repeat the above steps.
- Open up MSMTool.exe as an administrator and click 'start' only. Should take a few minutes, but you will have a good-as-new OnePlus 7 Pro.

I did yes, i pressed all buttons and the power button for 5 seconds and plugged my charger in. Then after that went on the MSM tool and it went straight to the fastboot. I really don't know but it loves this fastboot tool haha

Add: I made a video showing what I mean with the fastboot. Basically if i do anything with the phone fastboot it will just go back to the menu (sorry for bad quality)

It's one of those things where if someone was there with you, it'd likely get figured out. I've seen this kind of situation hundreds of times on XDA, and with all due respect, the problem is most always at the hands of the user. These phones are cookie cutter made, so there's nothing different (besides individual variants) that would make thee tools not function correctly, unless it's operator error. But that's not set in stone. Just don't give up. Try setting up your camera for an overhead view. I couldn't tell if you were plugging in your cord. And it seemed to reboot, instead of power off. Repeat the steps carefully, and see if you can achieve better results.
Don't give up! We're here for you ?

Make sure phone is powered off before plugging it in. Launch msm tool, Press the vol up and down key for a few seconds then plug in.
Edit : make sure your drivers are up to date too.

I don't know about msm tools never tried it but I know your situation.
Don't do fastboot flash boot twrp-3.3.1-4-guacamole.img
Remove the word flash. You are supposed to boot into twrp then flash the zip file to the phone.
look at this

Command in Fastboot mode is:
Fastboot boot "name of the recovery".img. Phone should boot to twrp. Then flash twrp.zip
or try Fastboot roms:
https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
Choose the one for youre phone (region)
MSM tool it's the last option.

Can't you just switch slots from fastboot or did you mess up both?

Firstly I'm terribly sorry for no response (same goes to everyone else looking into this matter for me. THANK YOU!)
However, I have done this multiple times in the past and it instantly goes back to boot menu. it sucks :/

If i'm honest with you.. i'm not sure in the slightest. My only assumption is no because the only thing I can access is only the fastboot. if i attempt to go into recovery mode it will go back to fastboot. when I flash twrp it will flash but it won't boot into it. It's confusing as hell.
Just to add to this whole situation:
Since I have no idea and just wanted it fixed in the day; i was willingly to give money for this phone to be fixed, but thanks to the person, he just made it a slower process by doing things i've already done.. going to pick the phone back up in an hour of this message.
I haven't used the fastboot boot twrp cmd yet, but from how everything else has been so far i feel like that won't work, but i will update everyone on that situation.
Just to add additional things that I may have not mentioned in the past will be below:
- Whenever i type in "ADB Devices" in cmd, it will not show up with anything. However, when I type in "fastboot devices" it shows it's serial and in "fastboot". It will only show as fastboot and i can't access the phone via file explorer in windows.
When i say "ADB Devices" it says *devices attached* and will show none of my phones details, but when i say fastboot devices it will then show the devices.
^ what i said above means I can't use the guap recover, or anything which means the phone has to be detected in windows, because other than fastboot, it won't work at all.
- So far I can't access twrp as a whole, so if anyone knows how to give me a guide on how to install it from where I am at, that would be amazing (if not, i'll try and reiterate what to do with the one given from a previous comment, so thank you )
- There was one time I was allowed in TWRP but i completely forgot how i entered it (so i can't explain), So i feel like there is hope in that aspect. I feel like i entered something via cmd so maybe there's a way?
In terms of hardware my phone is completely fine, there's not a single problem other than the software being a pain in the ***!!
if anyone can just spew out a bunch of help in different explanations it means the world because so far all I can see is that I wasted about £600 on an amazing phone because of dumb *** haha.
Thank you to everyone who has helped, and is helping

From your comments, you are not familiar with how Android functions. Not knowing the difference between adb and fastboot is an indicator that you should just endeavour to have a stock phone until you understand whats going one. It's also hard for people to help as no one has hands on and can see what is broken. Everyone here will be working blind like trying to fix your car for you from across the country.
Start the phone into fastboot and connect it to a pc. From a pc command prompt in your fastboot directory enter the command:
fastboot getvar current-slot
If the current slot is A then:
fastboot --set_active=b
or vice versa
fastboot --set_active=a
then fastboot reboot and see if you boot into the other slot.
Not knowing what phone you have makes it even tougher but I suspect you will have to reflash a clean complete rom via fastboot.

I do appreciate the help. If i'm honest with you the only reason I did this is to increase my data speeds (which from look of things is outdated now), and a longer battery life. I don't know much about rooting/jailbreaking but believe me that I have been in the scene for years, but not even knowing everything haha!
that being said.. i'm in twrp! thank you so much mate, i'll try and go and install the rom now. thank you!

Now install the zip twrp

Thankfully.. IT'S FIXED!
I didn't have to install twrp again or any of that. I simply changed the slot from A to B and pressed all buttons when it was showing the "! Your decide is unlocked" orange/black screen.
I had msm tools up and it detected and instantly installed the OS to the latest one and boom. It works again!
I got to thank everyone for helping me because without you people I wouldn't of been able to fix it. I looked everywhere and no help anywhere as I feel like it's pretty dumb to do what I did haha!
Thank you again people!

Oh you gave up on root?
You are supposed to read the instructions and follow them to the letter. When I read your post I realized you tried to install twrp like you would pre Oreo but it changed you have to boot into twrp then install it via zip file.
Anyways just remember that for next time.
