Need help. Phone has bad rom, can't access recovery

i may be up a creek now. i've tried everything i can.
here's the whole situation, maybe someone can offer some guidance on how i can get my phone back.
i installed this rom, http://forum.xda-developers.com/showthread.php?t=1835478, but did not see that there was a problem with people getting stuck at the initial google boot logo. i wouldn't have tried it if i did.
but it's too late now. so i too have that problem. in addition, i also have that problem with the nexus s in that the power button is busted, works only to boot the phone.
so i boot the phone normally, i get to that boot logo indefinitely.
i press up and power button i get to fastboot screen. for some reason the volume buttons don't work on that screen so i can't pick recovery there. only thing that works is hitting the power button and reboots the bootloader.
i plug the phone into my pc and i can't access it through adb, fastboot... does not recognize a device is connected.
so in summary, all i can do is access the fastboot screen or the boot logo screen.
if someone can help me figure out how to do one of the following: boot into recovery instead of fastboot, figure out how to use the volume buttons in fastboot, or get the phone recognized by my pc so i can use adb, that would be awesome.
i feel like i just bricked it for good....
thanks

Install the SDK. Launch it. Find the drivers to download in the SDK. Install them. Boot the phone into fastboot and connect it to pc. Open up a command prompt IN the directory that has fastboot in it. Type in the command prompt fastboot devices.
If your serial number shoes your good to go. Get the .img of your custom recovery and type fastboot flash recovery nameofile.img. with that being the exact file name ( hint type the first letter of the recovery and hit tab)

Yep, you gotta get fastboot working again. It's pretty important.

i've had the sdk/driver installed already.
like i said, the phone when it boots is not being recognized by the laptop at all, as if it's not even plugged in. so when i do fastboot devices, nothing shows up.

Was it recognized prior?

in the prior rom it was recognized by the laptop, before i tried to flash the rom i linked above that created this mess...

Yep fastboot is a great tool, if you have a nexus s then you MUST get it working!

Seems like your nexus s drivers are not installed in your laptop
google the nexus s usb drivers download them and put in the respective folder

was gonna ask the same question

like i said, i already had the sdk and drivers installed.
they worked fine before i installed that rom.
this definitely seems like it's on the fault of the phone, not the laptop.

looks like you got busted like a SIR!!
Just kidding man dont take it seriously...
I might sound silly but i hope you have tried this but if you have not then do try
Go here and try changing the usb plugs

IT shows flashboot steps, you need to connect phone in bootloader mode which you are achieving atm, and see if it works
and if it doesnt then let me know i will try to help out more if i could
P.S I am also new in android so pardon my noobnes

i went another route...
i figured i had nothing to lose at this point... so i ripped the phone apart and attempted to fix the power button, which i believed in turn would fix not being able to use the volume keys in the fastboot screen.
i was correct. i jiggled with the power button inside and it seemed to work. the volume keys now reacted in the fastboot screen.
i was able to then get into recovery, wipe the phone, connect the phone to the laptop and put a new rom on it.
i'm not sure if its fixed the button completely, but at least i can get into the new rom :laugh:

well thats a relief and i am glad that you problem is solved
a little advice, get repaired that power button for good so that you have no hassle in near future

+1, I agree with you. It does not cost much as well. I had this problem and was managing with apps. But finally got it replaced for good.

[Q] Hard-Bricked, no boot. Failed during flash

OK,
I was trying to flash a new ROM and had some issues where it would continously reboot so, after some reading it seemed like I needed a new version of TWRP, so I updated it. That didn't help.
I decided to reflash the stock rom on the device but after doing that, it wouldn't boot past the ASUS boot screen. So I tried again (via fastboot), same result. So I tried again and this time fastboot crashed in the middle of the load and now the tablet won't boot or anything.
It seems like the tablet still has power because windows makes a funky sound when you plug it in.
I saw this post but pressing the tiny button with a paperclip doesn't do anything.
Edit:
Windows can tell I plugged something in but says there is an error and doesn't recognize it anymore. Therefore, I don't have adb or fastboot access.
Edit: I installed the naked drivers and got it to recognize the device as an apx. I then pointed it to the normal driver and is recognizes it as an adb device but I can't connect via adb.
Edit: Nevermind, it came unplugged and when I plugged it in again windows didn't recognize it.
Where in the crap do I go from here?

Nothing, just the black screen.
I only know something is going on when I connect it to a pc I can here it connect/disconnect when I hold the power button or press the reset button. Also checked the hdmi output on another screen to make sure that wasn't the problem....it wasn't.

That was the conclusion I was coming to.
Now, for a nerdier question. If I had physical access to the processor, could I program it directly using it's programming ports?

Help - this is a difficult one

Okay from the top, have OPO that had paranoid 4.6 Beta 2 working just fine. Was playing with settings(dumb idea) and changed the runtime to ART like i have on multiple other phones just to try it out. Phone rebooted and upgraded all the apps like it should, but about 5 seconds after it booted, screen froze for a second and then it rebooted. Once it rebooted it was up for 5 seconds again and then rebooted again. thus started a continues reboot loop.
Using the five seconds i had i was able to race through settings and switch the runtime back to dalvik. this caused the normal reboot and fixing of apps however once it finished the boot process it began the reboot loop again and there was nothing i could do to stop it.
I booted to recovery and attempted to reflash the last update, that failed.
attempted to wipe cache and dalvik cache and that failed.
attempted factory data reset, that failed
NOW is when i made a mistake, on TWRP i checked system wipe as well as data and cache. Wiped everything.
So, phone was then entirely devoid of OS which is a slight problem. I was able to get into fastboot however and flash cm11s which i figured would fix it, false. Now when it boots the system ui crashes over and over continuously and it wont become stable. Went back to recovery but my twrp was gone and i just had cyanogenmod simple recovery. attempted to get to fastboot mode but its apparently nonexistent, i tried every combination of commands possible to get there but cant. so now im stuck with an unusable OS and a useless recovery and no way to get to fastboot mode that im at least aware of... if there are any other details that could help feel free to help, ill post pictures once i figure out a way to do that.
please, for the love of God, help me.

If you gold the power button for about 15 seconds then it should turn off. Then hold volume up and then press and hold power while still holding volume up for a few seconds and it should boot fastboot mode. Try erasing userdata from there to see if you can recover from the crashing.

I tried that a hundred times, the problem is once the screen turns off, if you keep holding vol up it never comes back on, its something i have never seen before and its exxtremely frustrating. Its like fastboot doesnt exist.

I wiped out everything on my Oneplus two months ago by mistake. Then my phone wont boot up because it had nothing in it except the TWRP. I tried EVERYTHING, to load a Rom into the phone, but it didn't work. It goes through the motion of loading a Rom into your phone and when you are about to hit the 100% level, it says FAILED. It wants you to check the debugging which you can't because your phone wont boot up. Anyways, I purchased a micro usb flash drive and loaded up the Rom into flash drive from my comp's usb. Then I connected it to my phone from TWRP via the micro usb port. After it loaded up the Rom from the flash drive, it booted up. Hope that works.

hey i hadnt thought of that, thanks ill try that as soon as i can get my hands on a micro usb flash drive, will the device find it using cyanogenmod simple recovery? twrp is gone for some reason.

Don't know if it will work without TWRP. I only see "Apply Update" then "Apply from ADB" and "Choose from internal storage". Hopefully the phone might recognize additional storage from the micro usb flash drive. Good luck.

The latest twrp supports mtp and you can use adb push to push the file to sdcard. Its really worth learning.

You should let go of the power button after the device turns off. Then vol up+power when the phone is off. This is different than what I read for the device but it works for getting me in fastboot.

Hey thats exactly how it started when i first reflashed cm11, but i managed to get through and force disable audiofx, from there though it just kept crashing system ui, i will definitely try this when i get outta class.
is there something different ill need to do based on having already disabled audiofx?

Disabling it will not fix your issue. My thread tells you what needs to happen. Generally when people decide to try new ideas without proper knowledge is when they get into trouble

Help me fix a bricked OPO :(

Phone memory was almost totally full and my sister was still shooting videos on it.
During one shoot the phone turned off and I can't turn it back on again.
Here is my problem, the phone just doesn't boot.
Shows only first screen with 1+ logo and then reboots. Not even the system boot animation.
When I try to enter recovery mode it shows TWRP screen and then reboots again. So I can't even access recovery.
And when I try to enter Fastboot Mode it turns on but the PC won't see it in adb.
What are my options here?

try charging the phone for a few hours

hi you need to follow this guide :https://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732

Hi.
Firstly, you have recovery installed, so that is good.
Some things for you to try:
Can you hold down the power button for longer than 10 seconds. This will clear temporary memory and hard reboot.Press power button & volume 'down' button until you enter TWRP.
Try this firstly.
Can you access ADB at all?
15 second ADB drivers should work.
What Operating system is on your Computer?
TWRP should pop up & be accessible
If you have Windows 10 on. If it doesn't recognize your phone you will have to run an update for Media Center for Windows 10 (64 bit...I'm assuming its not 32bit).
TWRP should be read by your computer if you can access it as it contains the drivers inbuilt.
If it still is inaccessible you might have to flash TWRP again through fastboot mode using ADB.

Yes, I have TWRP installed, but cant access it. Shows the TWRP splash screen and then reboots after like 10 seconds or so.
ADB does not see device. Only shows the device during that 10 second TWRP splash screen time, but even then no commands are effective and it just reboots.
Already tried holding down power button for few seconds. No luck.
I already installed all the possible drivers and media feature packs on my Windows 10. Still no luck.
And yes, I am running latest Windows 10 Pro x64.
And no, since I cant access Fastboot, I can not re-flash TWRP either.

Daaaamn I really frankensteined the sh*t out of this one
I tried that Color OS unbrick method but it did not work. I mean the process itself worked, but the phone would not boot past the logo.
So I grabbed the system.img from old CM13 image, grabbed 2016 modem.img, then placed twrp.img instead of CM recovery and pressed START.
AAAAAND IT WORKED!!! The phone is alive!!!
Now I am in TWRP and I'm going to flash a new ROM. Hopefully everything will go perfectly.
Thanks a lot for your help @kallum7
EDIT: Flashed new ROM. Everything went just fine.

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.

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?

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:

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.
