[Q] I installed whispercore without creating a restore image and want to leave. - Nexus S Q&A, Help & Troubleshooting

I'm having trouble getting back to a regular non locked down firmware. I flashed whispercore without fully understanding that it was actually in fact changing my entire rom.
I didnt even think to try and install CWM first to create a recovery image I need help getting out of this mess. I've used the Whispercore installer to unlock fastboot because whispercore relocks your fastboot after it does its thing.
Seems as though the stock sdk tools hated me for a while there and wouldnt detect my device than I later realised it was just because the sdk downloads itself all fragmented it basically took fastboot and adb and separated the two even though fastboot requires adb to function properly. I wont even begin to speculate as to why that happened, as thats beyond the scope of my question.
I basically have gotten to the point where i have Clock work mod (CWM) installed on my droid and the fastboot oem unlocked but am currently stuck at trying to get Cyanogenmod 7 stable on here.
***UPDATE**
Ok. This situation has been resolved. If you are having trouble with leaving whisper core and you've flashed a bunch of stuff trying desperately trying to fix this issue. Recognize the nexus S is a very easy device to fix. Fastboot is your saviour and the WhisperCore installer will even be kind enough to install all the drivers required to OEM unlock fastboot and do it for you.
Anyways the solution was: Re run the whispercore installer. Let it do its automagic.
Than flash a new Clockwork Mod recovery image this thread provided some clean Clockwork Mod images for flashing with fastboot that link is also for rooting but provides a good example for how to flash a new recovery.
Than Just reboot into recovery and use it to mount your phone via the Clockwork Mod recovery console to your computer, upload your favorite flavor of rom and than unmount the device. Once unmounted go back to the main menu in Clockwork mod and "Flash zip from SD" look for your rom in my case it was update-cm-7.0.3-NS-signed.zip Latest stable at the time. let it do its job.
Basically my issue was a combination of several factors. A bad Clockwork mod and a semi corrupt installation of SDK tools and Whispercore.

Possibly a stock firmware might be required first I just know that trying to straight flash cm7 stable from cwm is not working out.

you can get adb and the 2 dll files and fastboot in the same folder and cd to that directory. fastboot oem unlock should unlock your bootloader. then you should be able to flash a recovery if you want. might also want to check out the 1 click stock thread to see if that works.

I will probably have trouble finding this thread but I will look and if i come up with anything I will certainly post my findings.

This should work. But we shall see I will update the original post if I find a full solution.
Just flash a stock full rom (for i9023 you can use the one in my signature, don't forget get to use the wipe options in cwm recovery before) and the root should be gone. Afterwards, boot into bootloader and use fastboot command "fastboot oem lock" to lock the bootloader again. Than you can do a factory reset (and delete usb storage) to fully restore stock "experience".

I am trying to follow what you did and i am completely lost... I have a nexus s g that i am trying to get whispercore off it!
The "Automagic" you talk about. Isnt that just whispercore putting it in fast boot??? If so then then how do you use the recover image?

[Q] I think I bricked the xoom after 4g upgrade??

- This is pretty much an exact duplicate of a thread I posted on Xoomfoums, but I think it maybe better here...
Anyway, really looking for a miracle!! I got my xoom back from Moto yesterday for the 4G upgrade and I tried to root the device the same way I have done before. I got as far as unlocking it. The last thing I flashed was a “bootloader_patch” from a guide on Xoomforums. Now I’m stuck and I only found one person who had this issue …… he returned his device for a new one
So summary thus far.
- I can get into Fastboot support and flashing always yields “success”.
- I seem to have no ADB connectivity. (don’t know if I really need it for fixing this issue since I can fastboot and flash).
- I have tried, stock images, CWM recoveries, rogue recoveries, also some HLK75 imgs, etc!! All leave me at the same place.
Where am I stuck:
- I reboot and let it go normally and she hangs at “Moto screen”
- I reboot and tap the “volume down” leaves our three choices….
-- Android recovery -> tried to enter recovery and sits at the famous “Reading ODM fuse:1”
-- Fastboot -> That works, I can flash from here OK
-- RSD support -> Haven’t played with that, I have read people going to dark places when they screw with this. If I have to I’ll do so carefully.
All the methods of going back to OEM are epic fails. Nothing new happens, but I am always left with the same result.
Any help you could lend would be greatly appreciated!! I really would rather truck through this than return it however I’m afraid if I don’t get rid of it soon it will be harder for me to make an excuse to the retailer.
Thanks - John

When it sits at "Reading ODM Fuse1" can you press power to see if it will select that option and take you into CWM recovery (assuming you have that installed)?
When you say you are flashing from fastboot protocol, are you connected to your pc? What are you flashing? I'm a bit lost with your description...
^^^
Thanks for the reply. Good suggestion on the power button.. press as its sitting at "Reading ODM fuse:1" but....... not good
So I didn't list all the things I have flashed because I tried many many fixes from multiple guides. I could look through all the links if you want the exact names but none of the made a difference. Yes, flashing from my PC connected via USB.
So after the first root guide blew it up I tried to flash a bunch of recoveries and system images. I also tried to bring her all the way back to OEM using the appropriate guide. No matter what I flashed I was given a successful message but it still gets stuck at the same screens. Nothing gives me any different results. I'm wondering if the actual bootloader is hosed. If so can you flash a new bootloader?
Here's some stuff I have flashed along with some links....
recovery-Tiamat-R4c-100611-1150-cwm.img
MZ600_HRI66_OEM_Image
how to root guide that I origianlly followed.... http://www.xoomforums.com/forum/mot...ow-root-3g-4g-wifi-only-xoom-stock-3-1-a.html
Someone got the build img after the LTE upgrade, so I tried this....
http://www.xoomforums.com/forum/xoo...rade-stuck-recovery-reading-odm-fuse-1-a.html
I also tried from fastboot erasing all the partitions before I flashed them and that didn't help.
Thanks for your time!!

Well, you are flashing wildly but not well, (JK)
This thread should help you:
http://forum.xda-developers.com/showthread.php?t=1299485
Here is a great post by Saintfyre (I think it fits the bill):
"Yeah join the FUBAR Club.
I was in the same boat as you did the same thing.
I now have my Xoom back to HLK75C and have 4G/3G and Wifi connectivity again so all is not lost!
What I did to fix my situation:
-I wiped the Device and just went through Solarnz's Root Method here: http://forum.xda-developers.com/showthread.php?t=1074979.
-Download the HLK75C (This is the build the 4G Xoom's shipped back with) file that AceXMachine provided here, post #6
-Extract the File to your Android SDK Platform-Tools folder, password is AceXMachine
-Follow his instructions to apply the images. I copy pasted but all credit goes to him for putting this out there.
On Windows shift and right click the Platform-Tools folder -> Open Command Window here.
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase cache
fastboot reboot
After following all of this I had my Xoom back just like it had come back from Moto after the upgrade. I've since then flashed the Tiamat Tachi OC GPU Kernel to have Overclocking again. No issues since then, have full 4G/3G Connectivity and Wifi has no issues as well."
From this thread:
Yup.....I tried that one as well, it didn't work either.
I really think the bootloader is shot. Is there a way to repair it? I think what killed this was the last .zip file I updated as part of the root guide I was using, it was "bootloader_patch.zip" found here..... Bootloader_patch Does anyone know what this does??
**edit: Is the boot.img the bootloader?? If so ... forget it as I already tried flashing a couple new ones during my attempts to bring it back to OEM.
So my logic now is rather than keep flashing like crazy let me try and get recovery working. For this I will try and erase everything using fastboot (my only option) and then flash a boot.img and a recovery.img
Questions:
- Will keeping everything earsed from the device except for a boot.img and a recovery.img allow me to get into recovery? I want the minimum amount of partitions flashed. I want to just work slowly and systematically trying to get into recovery first.
- I do not have ADB support, can this be a hint? Shouldn't adb support be working or do you need to have somthing in the system / app partition for ADB to communicate with. I know its called Android debugging bridge so the name makes me believe that I need an android OS loaded and this is why my ADB doesn't work.
Please take a look below and let me know if anyone has any suggestions on different boot.img or recovery.img Ihave not tried. Also, I'm wodnering which ones I should try in combination.
Going forward I'm going to keep track of each combination I try as to avoid duplicated / wasted effort.
recoveries I have tried:recovery-Tiamat-R4c-100611-1150-cwm.img
recovery image from steady Hawkin (3g/4g Stock Images for HR166)

How have you flashed zip files without ClockworkMod recovery? It's hard to brick a Xoom but you may be close.
If there is anyway to flash your device's stock images through fastboot, that is your best hope at this point.

Yeah, so I have another thread running on xoomforums and I have explained over there that just about 30 minutes ago I erased everything and reflashed the "HRI66" files. I used everything from that build so there was just the stock recovery, etc. I even did a fastboot oem lock. This didn't work either.
After this I was able to return to fastboot and "unlock", so now I am just back to where I was before.
Me and one other dude think I have a corrupetd / damaged partition or semi-destroyed bootloader. The thing is I can't get an answer to a real simple question.....
is the bootloader a "flashable" component?? I'm not sure if the boot.img IS the bootloader or the bootloader is something else that's not flashable at all. If the later is true then maybe my bootloader is FUBAR.
Thanks!! John
I'm the other guy jadkar was referring to from Xoomforums. He's pretty much put it succinctly but here's my version
ggrant & fish over at Xoomforums suggested we PM solarnz (etal) or post over here for help. I am writing this for myself and another Xoom user. We've both sent our Xoom's to Moto for the 4G upgrade, received them back with 3.2.2, and then proceded to root the wrong ROM over the top. The result was a hang at the red Logo. In hindsight, we should have used Universal Root.
We've both exhausted the experience at Xoomforum (hence our plea here Anything you can suggest would be most appreciated. Personally, I think something is awry in the recovery partition size (perhaps changed by Moto at the upgrade?):
To save the basic suggestions off the bat, we've done the expected already: Installed moto's drivers, tried new cables, AND an entirely different computer. We've tried completely erasing boot, system, recovery, cache and userdata partitions, and flashing back the stock HRI66 images with fastboot.
ADB doesn't recognize the 'devices' command, only fastboot see's the Xoom. Accordingly, the only way to get into fastboot protocol is to Vol Up + power, and wait the three seconds and toggle. We can both toggle (with Vol) into Recovery, RSD and Fastboot). After flashing MULTIPLE flavours of Recovery images, the result is always the same: Recovery hangs reading fuse: 1. There's never the Recovery menu or graphic of the the Droid robot.
As for RSD, I've tried all the way through RSD Lite 5.0 with the thought of using solarnz' (I think) recovery.SBF. The result there is always the same as well: By toggling into RSD mode (Vol+Power into RSD), RSD Lite see's the device OK, but shows an error stating initialization values cannot be read. Note this occurs immediately upon plugging the Xoom in, even before TRYING the SBF file, which BTW, fails even if you try.
Via fastboot, we can oem lock and unlock (note however that in the command window, it states that it failed due to too many links, the the action seems to have worked on the Xoom anyway.)
So, it's down to THIS; the common thread for both of us is that we cannot successfully get into recovery, no way, no how. Again, ADB won't recognize the Xoom, only Fastboot
Any help would be APPRECIATED!
P.S. John, if we don't get help here, I have a 9mm with two spare rounds (for the Xoom's, not us!)
^^^
Thanks .... we'll see if anyone bites.... I hope so
As for the 9mm ........ Thanks but I have a flight this morning and I'm seriously thinking about dropping the Xoom out my plane from lets say 3500ft!!
LOL! Safe flight.
Guys, you all are crazy!
I appreciate your resourcefulness, but it sounds like you're almost out of options, lol.
If you can get to 'starting fastboot protocol' you are not bricked. If you cannot connect your Xoom via adb while your Xoom is in fastboot, it usually indicates that there is something wrong /missing from your setup.
Are you sure you have all your moto drivers installed and the proper image files in your platform tools (or tools folder) and you are actually in the right directory when opening the command window?
Please try to follow the instructions in the following
thread before you commit mayhem on your innocent Xooms.
http://forum.xda-developers.com/showthread.php?t=1249798 for setting up everything you need to ensure that adb will work and a proven method to install cwm recovery and root once you have been able to get back to a proper stock image. What I can't find at this moment are the 4G stock image files. You need the following to flash through adb/fastboot: system.img, boot.img, recovery.img, and userdata.img.from the Honeycomb 3.2.2 4G Xoom.
Commands to use:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot reboot
Don't give up...good luck!
Found out another guy tried 2 different PC's and it did the same thing. He even reloaded android sdk. He decided to try a 3rd PC that he had to load sdk to. It worked! So he found there is an issue somewhere with his 2 PC's sdk or windows install. When I got my xoom in June sdk would see it, but I never rooted at that time. However I did update and install all the new stuff for sdk.

That would be the ONLY thing we haven't tried. I know how to lock/unlock, flash images, etc. We've both done all of your above instructions to the letter. I've already replaced my Xoom and it's at Moto having 4G surgery, so I can't do any more of this now. John will have to try again, but as (I hope) you've already read above, the status quo techniques are not working.
Any clues about why a successfully flashed recovery image isn't working?

Lots of stuff to answer back here, please don't mind the bullet points....
from your guide... "Did your device not show up? Make sure that you have USB debugging enabled in Settings/Applications/Development on your Xoom."
- I have no devices connected when typing ADB devices and based on the above how can I make sure I have USB debugging enabled if I can't even get to the Android OS??? I have fastboot support that's it, I don't think its possible for me to get ADB to connect with all the partitions erased. ADB or "Android Debugging Bridge", the name implies you NEED android on the device to use it. I don't have android since the system partition was erased.
- I have two different 4g images from AceXMachine's posts. However his build posts only have system.img and boot.img. So based on your instructions I need to know what userdata.img and recovery.img I should use.
- I keep asking and I will continue until I get an answer on the next question..... I think the bootloader is screwed up. I want a new one (or at least the one that came from my 4g upgrade). Where can I find one? How do I flash it? Is this synonymous with the boot.img?
Thanks!!!
Well, your issues are way, way, way beyond the scope of my limited knowledge, lol!
Have you tried to chat with the developers on #Xoom on freenode.net? Bigrushdog and solarnz are both really nice and so is SteadyHawkin, if he's on there. Someone may be able to help.
Good luck!
Flash it back to stock moto!!!! Then start over with bringing your xoom to 3.2.2!!!! That is why you can't get anywhere! You keep killing off everything! AceXMachine did the same as you and he has his xoom back to 3.2.2. Or send it to moto and pay them to flash you back. You are not doing it right period! You have posted the same issue and people have tried helping, but you seem to want to keep going into rsd and other crap you don't need. The baseband is in the boot.img. Flash the hir66 then update to the hlk75c.

mmmkay... well THAT was a little terse. Don't you think returning to the HRI66 stock was the FIRST thing we tried? We downloaded the stock images from the provided links, checked the MD5, and then did this:
adb reboot bootloader
Xoom will then reboot into bootloader screen
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
Use volume rocker to select ok and then xoom will reboot. At this point you should be back to a factory state which includes being locked and unrooted.

Isn't THAT what you suggested? Yes? No?
^^Hammer....
I know this threads is really long and probably didn't read all of it (don't blame you) but a while back I explained that I did try and flash everything in Steadyhawkn' HIR66 build. I flashed the 4 images included (boot, system, userdata, recovery) I also went as far as an OEM lock at the end. This did nothing. I tried this a couple times.
Can someone lead me to the patience pool; I need a drink.

Ok! first download : http://www.4shared.com/zip/XG506hyV/icsroot-fastboot-recovey.html
just unpack, connect your device and click run.bat.....Good luck!
I ran the .bat, but I get an error saying "Device already rooted", but it is still not recognized as rooted by SuperUser.
Alternatively, is it possible to completely wipe the phone of everything (including root) so I can start over with a fresh phone?
Of course you can, and might be the best idea if you don't mind doing it.
Make sure you have the latest CWM recovery on your phone, download the FULL ROM from this thread (i'm not american so i don't know exactly, but from what i know yours is the I9020T, so get that ROM) and copy it to the SDCard. Now go into recovery, wipe system/data and dalvik cache, then flash the ROM.
Do make sure you have the right ROM though. This will get you 100% fresh and untouched 4.0.3. You can probably clear out any non-personal folders on the sdcard too, but that shouldn't do any harm anyway.
After this, use the attached file from this thread to root, and feel free to update root/superuser.
Actually, that's what I did...I can't use CWM recovery because its displaying an error of no root. So how do I wipe this or fix CWM?
Is your boot loader unlocked? And are you trying to flash cwm through fastboot?
Note to backup your sdcard if unlocking the bootloader.

My bootloader is apparently unlocked and I'm trying to flash through fastboot.
Are you sure the following is satisfied:
-open padlock and google logo on boot
-fastboot (on phone) says "bootloader status: unlocked" or something of the like
-you are using: "fastboot flash recovery "C:\path\to\recovery.img""
-you are using the above command while connected to the PC via USB (with working drivers) and that you are in fastboot mode on the phone (turn off phone --> hold Vol. Up then hold Power TOGETHER for about 2 seconds, should give you reboot and recovery options)
It is necessary to be in the bootloader/fastboot interface on the phone when you run the command. Hopefully it was something simple that i said above, otherwise i'm completely lost.
1. Yes
2. Yes
3. I didn't use that method to root...
4. I'll try that.
3 is just flashing recovery, that is the code u type into cmd/terminal to reflash the recovery img. It isn't rooting the phone. 4 is how to get into the mode on the phone to use the command.
Its a bit confusing at first but makes much more sense once you do it one or two times.
Where do I go to get the recovery image?
The latest ClockWorkMod Recovery can be found on this page. Just scroll down to Nexus S and download 5.0.2.0 crespo .img. Then just direct fastboot to the folder you have it saved in while using the "fastboot flash recovery C:\path\to\recovery.img" command.
Ok. I've tried this, but in command prompt, I get the following error:
C:\Users\Bruce>fastboot flash recovery C:\Users\Bruce\Downloads\recovery.img
'fastboot' is not recognized as an internal or external command,
operable program or batch file.
Check out this rooting guide, however only go up to step 5 (and do NOT type "fastboot oem unlock", do everything up until that point). This will setup fastboot for you, and setup drivers for your computer. Once this is done, do what you did above and it should work successfully.
Remember to cd (change directory) in cmd to where you unzipped that folder.
There isn't a link...
Sorry, stuffed that up. I fixed the link in my previous post pointing to NexusSHacks - How to Root Nexus S.
It's worked, but when I try to go to the recovery menu, the Google/unlocked padlock screen freezes or it displays an Android with its chest compartment open and a red triangular ! symbol.
I just had a really long reply and managed to lose it by closing the page..
That's the stock bootloader you see there, it probably didnt flash or you rebooted your phone. And make sure that you are flashing the latest CWM you downloaded before.
I flashed the latest CWM, but when I try to go to recovery, my phone freezes at the Google logo with the unlocked padlock.
Have you tried flashing it again, or maybe redownloading the file? And of course making sure it is the NEXUS S version which you are downloading.
Alternatively, try just "fastboot boot recovery.img", replacing recovery.img with the full name and path of cwm.
edit: btw, i'll be gone for an hour or two Bruce so i can answer any more questions/issues when i get back

TF300 Wont boot past ASUS Screen

When I hold the power button plus Volume down key I am only getting two options. One is to wipe data and the other is to enter USB Fastboot mode. I just upgraded to the latest TWRP recovery and when I click the Wipe icon the TWRP splash screen shows up for a second. What I am hoping is that someone has some insight as to why the recovery icon has disappeared and how to get it back. Usually I am not the person asking the questions generally I am the one answering. If anyone has a clue it would definitively help. I did search and found a couple threads where something similar happened but there was no direct answer as how to fix it. Please help.

I had a similar issue when I restored a TWRP backup I made with pre version 2.2.1. I was able to get help from the Dees_Troy on IRC.
Notes from IRC conversation
Whatever you restored from your pre TWRP 2.2.1 old backup is not a kernel. The dev that made the original device configuration files for the 300 couldn't find boot . So he just threw boot onto the wrong partition you need to install a working kernel via fastboot.
Steps that got me backup and running.
1. Flashed latest TWRP via fastboot. 'fastboot -i 0x0B05 flash recovery twrp.blob' rebooted
2. Downloaded a cm9 rom and opened the zip file and extract boot.blob . Flashed with 'fastboot -i 0x0B05 flash boot boot.blob' then rebooted.
Now TWRP recovery worked and I was able to install a new custom rom.
Backups made with version 2.2.1 or grater work correctly for me now.
Thank you Thank you Thank you!

hey Im sry I never posted here b4 but I think this thread is the closest to the problem I have. My tf300 jad 4.1.1 ota update, i decided to change the rom since it seemed to have so many advantages. I installed TWRP correctly and according to the process I made later with debugfs tool I got root. It was all good but then I messed up, I installed Hydroponyc rom without backing up my rom and from then on, all hell broke loose. I can acces Clockworck (I changed TWRP for clock thought it might help......) and fastboot but any rom I install it doesnt go past the first asus logo that says device is unlocked on the upper left of the screen. Is there anyway u could help me please? Forgive my noobness I never posted here b4 I dont know if Im breaking any rule but i dont wanna wind up with a very expensive paper weight.
Did I brick it?

hey I was super frustrated by this but I took some time out and then I found this post I tried it and it worked perfectly give it a shot
Looks like partition sizes chaged with the Asus update. I couldn't flash CM10 or any other rom as well (signature mismatch). If you installed the official 4.1.1 update, you need to manually install it again. Older versions and rollbacks wont work unless you push to some trickery mmcblk0p4, but that's another thread in itself
Download the JB update from Asus's website (if you still have it, that's fine) and extract the blob file. Put the blob file in teh same directory as your fastboot. Boot your TF300 into bootloader and enter:
fastboot -i 0x0B05 flash system blob
It will take a while to install, so be patient. Hope this helps

UPDATE 3: Looks like it's working!
Dude, thank you so much! I'll fool around with it. Is there a root method working already? I was wondering if there's a way to restore my backups, at least the ones I made for my gaming progress.

you can flash the file named "blob" extracted from stock JB zip file(download from ASUS website,now there is only US SKU,10.4.2.29),it's about 7XX MB,then use the command "fastboot -i 0x0B05 flash system blob" (put the blob in the same directory with fashboot),It will restore your JB OS.till now,other rom can not work by this way.

What if you can only boot to APX mode? I only have the option of using that because my unlocked bootloader got erased in the process of updating to JB. Is there a way to install a bootloader using fastboot? Or will it only work with an existing bootloader?
In other words, when I issue the fastboot command
fastboot -i 0x0B05 flash system blob
I get "waiting on device" and nothing happens after that.
Thank you, this worked !!!!!!

[Q] Google OG Pixel problems soft bricked

Hello everyone,
I have an OG Pixel 5'', the stock Android was 7.1.2 and I updated it to Android 8.1 Oreo. Bootloader is unlocked, and I am able to install a TWRP 3.2.1-0 no problems. Phone at the time worked well. Now I have tried to flash an ElementalX Kernel on my device. This worked and I managed to boot. However, a message "There is an internal problem with your device, please contact the manufacturer". There is a thread to fix this and I should have done my research better.
Anyway, I went into TWRP and did a complete wipe of the phone, thinking that I could have just boot into TWRP again and copy the stock flashable zips to reflash the ROM.
It turns out that:
a) TWRP doesnt work. I.e when I got into fastboot mode (Power + Volume Down) and selected Recovery, the phone flashed to screen with Google image and then flashed back into the one with the green Android.
b) I managed to boot twrp via fastboot from my computer. So I booted into fastboot mode, and then on my computer, did: fastboot boot <twrp3.2.1.zip>. This worked and I managed to get into TWRP again. However, I cannot transfer file to flash. I.e when the phone showed up on my computer in TWRP, I cannot drag and drop anything into mounted folder.
I have tried the following to get stock ROM from this website: https://developers.google.com/android/images
a) I decided to look at ADB Sideload. So from the above website, I downloaded the zip files under Full OTA Images and then in TWRP, I went into Advance and chose ADB SIdeload. On my computer, I did "adb sideload name_of_zip_file_downloaded". The process started but ended very quickly, the finished time was 0.00 second, which means that nothing happened. Clearly, TWRP console showed that it is unable to mount /data and other folders. I guess the reason is that I am running a "live" TWRP? I checked by going back to TWRP mainscreen and tried to mount. However, all hard drives show 0MB (OTA USB and the main drive).
b) I used factory images approach by downloading zip from the same website, but this time under Factory Images. For this one, I unzip the files to a separate folder. Then I did flash-all.sh script but it said that my fastboot is too old.
So... to fix fastboot, I tried: (I am on Ubuntu 16.04.02)
a) Remove whole android fastboot with sudo apt-get remove, then reinstalled => Did not work. Still fastboot is too old
b) Download entire Android SDK from here: https://developer.android.com/studio/install.html. Fastboot still didnt work
c) From the Android Studio website, I tried to download just the command line tools. However, I could not find the folder with fastboot in it. A Google search shows that the fastboot and adb should be in platform-tools folder. Couldnt find any
Once again, I apologize for a very very long thread (It's 5am and I am trying to figure this thing out). Please, let me know if you guys can offer any help. Any help is greatly appreciated. FYI, I am coming from a Moto Z Play, and if things happen I would just boot into TWRP and copy the zip over. Clearly, this is not the case. This is my 1st Pixel as well.
Please let me know and thank you very very much.
Installing ex messes with the boot.IMG you need to reflash twrp after. Also don't manually flash stock zips that doesn't even make any sense. Download the latest android sdk or base platform tools then get the latest factory image and extract it into platform tools. Then go into fastboot and manually flash the official factory image
To use fastboot on ubuntu you have to put sudo infront of the command: sudo fastboot ........, Because of a permissions thing.

Thank you everyone. I have managed to reflash the OS. Gonna stay with stock kernel

I personally recommend using a custom kernel just make sure to follow the OP exactly. As the kernel and twrp are usually stored in the boot.img together and the kernel overwrites the boot.img the problem was likely that you just did things in the wrong order which would cause twrp to be removed. Typically the order of installing custom stuff from stock goes this way: flash_all to restore stock boot.img, boot twrp, factory wipe, flash rom, flash twrp, boot rom, reboot into recovery, flash kernel, flash twrp, reboot system, reboot recovery, flash magisk. Some rooms vary as they may require you to do things like flash a vendor img or delete the vendor overlay folder(always follow OP).

Installed TWRP to Boot, want to boot myself in the a**.

Own the OPP6; Rooted, on OxygenOS 5.18.
Went to install the newest TWRP (was going to install XXX no limits), when asked where to install it to, accidentally, without thinking, hit install to Boot.
Problems.
I can get into fastboot, the PC sees the phone in fastboot.
Have tried to flash a recovery image and similar, got an error saying: FAILED (remote: (recovery_b) No such partition).
Just want to get the phone booting again, wipe the whole thing start over, from fastboot.
Any help appreciated.

What you should have done was fastboot boot twrp.img. which would start twrp, then you could have used the installer in to install twrp on phone. After that you would have to installed stock or custom kernel.

That is exactly what I wanted to do.
I could get into TWRP, but I couldn't see the phone on the PC and couldn't move files (ROM) to the phone (although fastboot was working and I could see the device using adb) but I couldn't figure out how to have TWRP look for or find the ROM on the PC.
There's no recovery partition on A/B phones remember.

Thanks for that. and that explains a few things and explains why when I installed TWRP, I didn't see the recovery option. Doesn't pardon my hitting install to Boot.
Just thought of another Q, if there is no recovery partition, where is the OEM recovery stored? (I figured the lack of a recovery partition is why TWRP gets overwritten if installed without a custom ROM)
I did a quick read on that, it seems really interesting and may be of some use as soon as I learn more.
I've got so much to learn about this. I keep meaning to take time to begin, but stuff comes up and boom more changes.
I've got to do more reading to take advantage of that.
@MrSteelX mentioned that I could have used TWRP to install a ROM from the PC.
Is this what is referred to as "sideloading". I've been looking for some info on this and haven't really come across much that is any good.
Are there any available guides that anyone can point to so I can learn about using TWRP that way?

In twrp, you go to advance/sideload. Twrp then waits for adb sideload to push file to phone then auto flashes file.
In your case, you would sideload rom to flash and have been go to go.

If you have working fastboot mode and getting detected via fastboot then
fastboot flashable stock rom via fastboot mode.
U don't have to do anything just downloaded zip file unzip it any folder u want. Connect u r phone to. Computer in fastboot mode
Then go to that folder and just click flash all bat waut for 10to 15 min and then phone boots in working oos.
(all data will be get wipes after this)

Thanks for the link/guide. I had been trying an iteration of this (and the guide) but after reading your link, it too explains some things. I was trying to restore a Stock ROM from fastboot according to your link:
Things are changing with the advent of project treble. OnePlus will no longer release ROMs flashable via recovery (either stock or twrp) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlcoked. This will erase all your data and will wipe
I download and was trying to use the stock ROMs, I didn't see any bats, and now I know why.
Lots more reading to do. I love doing playing with this stuff, but trying to learn & keep up with things burns time, which most days I don't have.
This is the longest I've ever been on a stock OS (6 weeks? got the phone right after its release) although it's rooted (can never leave things completely alone).

"recovery" (what's left of it... wipe and mostly nothing else) is inside the boot partition. TWRP on those devices is installed into the boot partition (NOT overwriting the boot partition, but into the "ramdisk", a part of the kernel where OEM recovery resides and where TWRP, Magisk, Xposed and all the mods do their stuff on the kernel. On a phone with A/B partitions, you have to fastboot BOOT twrp, and then you have to flash the installer zip, you should never ever flash the image to any partition since there isn't any.

Thanks for the information.
and this is what I did, originally I thought I had accidentally selected the wrong partition, but it seems since there is no recovery partition, I did it wrong from the start.
Q: I'm guessing this is why when you do load TWRP (the correct way, which I did once, following a guide) without a custom ROM (still using Oxygen OS) that the OEM recovery overwrites TWRP or the OEM recovery is called up at the next reboot into recovery?
Q: I understand, at least in theory the benefit of the A/B partitions, what is the benefit of eliminating the recovery partition other than giving more control of the phone to the OEM and OS? Is this setup limited to the stock kernel or mandated to be copied by any potential replacement kernels (this information is new to me, I haven't yet read up on kernels).
