fastboot mode not working

hi everyone, i'm trying to install CM9 on my LT15i, i've tried using the CM wiki instructions and both the following guides...
androidauthority.com/xperia-arc-lt15i-root-android-4-0-ics-80265/
and
androidforums.com/rezound-all-things-root/506466-scottys-noob-friendly-root-guide-start-finish.html
the phone is already fully unlocked and has CM 7.2.0 anzu installed. i've tried simply using the clockwork recovery mod bootloader to wipe the phone and install CM 9.0.0, but on reboot the phone gets past the boot logo then just shows a black screen, so i assumed i needed to flash an appropriate ROM for CM9; this is where my problem begins.
every forum i've read about this process says i must enable usb debugging (done) and "disable fastboot" under settings>power, i do not have a "power" option in my settings and cannot find anything related to fastboot on the phone; although i'm not sure this is the problem. when android is running normally and i attempt to list devices with adb.exe on windows, it successfully returns the phone's serial number. when i shut the phone down, hold the menu button and plug in the usb cable, fastboot mode appears to work correctly as the LED comes on blue and "android adb device" appears in the windows device manager (i've tried installing the arc usb/adb drivers from various sources, they all seem to work correctly). but when i attempt to list devices after restarting in fastboot mode, adb.exe says it cannot find any device. fastboot.exe has not communicated with the device whatsoever, but i assumed i might need to get the adb.exe usb daemon/server running correctly first for this to work.
i did this process once already when i installed CM7, it was successful the first time and everything went smoothly. from what i recall i just did exactly as described above and fastboot.exe was able to find the device no problem. but that was a number of months ago, hopefully i'm just missing some obvious step.
cheers

There is no such thing. And USB debugging is only required if you want to root stock ROM, every other action can be done without it.

Drivers, drivers, drivers.
If your phone is in fastboot mode, make sure drivers are installed. Proper drivers.
You do not need ADB server for installing a kernel.
Just open up Command Prompt and install the kernel with command
Code:
fastboot flash boot boot.img
.
Assuming boot.img is in the same folder as fastboot.exe.

thanks for the reply someguyfromhell. i've tried every "android adb interface" driver under the sun for the S1 fast boot device that appears in the windows device manager when i put the phone in fastboot. when i try to send any command with fastboot.exe it just hangs at "waiting for device", i've fiddled with this stuff every which way and just cannot get fastboot.exe to see the phone. i've tried switching up the usb ports on this computer, but haven't had the opportunity to try a second computer. you've let me know i'm going in the right direction at least, if i have the same results on a second machine i'll pursue the issue further.
thanks again

You need to unlock bootloader, if you want to install CM ROM. Arc S can only have bootloader unlocked via official method, there you can also download the correct driver which you need.

the bootloader is already unlocked, as i said, the phone has CM7 on it currently.

S-offed and unlocked bootloader via Sunshine...now I can't get TWRP installed...

As the title says, I am stuck here. I CANNOT get ADB to detect my M9 after I type fastboot reboot bootloader or fastboot reboot download...not sure which one I am even supposed to use though tbh, as I cannot find a even half decent guide for this device...I found the download one on the normal M9 page and the bootloader command on TWRP's page for this device. Not that it matters, as neither works as my device isn't detected and they both hand on 'waiting for device'. I have uninstalled and reinstalled about every damned usb driver I can find, manually installed them, used installers, different cables, different usb ports. rebooted my phone and my PC over and over, etc. I am about to pull my damned hair out here lol.
Anyone have any experience with this or a link to a guide for this specific piece of locked down peice of crap?

Welp...after 7 hours of fiddling...it randomly worked. I did literally nothing. Just tried adb reboot download again. And it rebooted and accepted the flash...I suspect there was a weird driver installation issue with windows 10...but I'll probably never know.

I know this is fixed but this post is simply an FYI for others that may have trouble.
I've had trouble instelling TWRP. It would randomly give: the command is not recognized or some sort error message.
*****Before beginning, find your device's firmware number by booting to Download mode. You can do this by restarting your phone and before it begins to reboot, hold the volume down button. Once in the black screen, look for something that says Firmware or "3.37.305.7" The last 4 digits will be different depending on your country and device carrier. This firmware info specifically will tell you which version of TWRP you need to download and which version of SuperSU you'll need. Example, I run a US Verizon phone so I needed TWRP 3.0 or above and SuperSu 2.64 (not anything higher than that). Using the wrong TWRP and/or SuperSU caused my phone to brick to a white screen with red lettering. To fix it, I had to reflash back to stock and then try again. (unfortunately, which combination of the two you'll need is something you'll have to search for as I don't have an exhaustive list. But I highly recommend you verify before flashing the recovery)***********
For me I fixed it by:
- Ensure USB Debugging is enabled on the phone,
- re-downloading the HTC M9 drivers,
- Downloading Android Studio Bundle 145.3
- Searching my computer for "ADB.exe" and found it in "C:\Users\7\AppData\Local\Android\sdk\platform-tools" Your location may be different as I'm running Win 7. They key is that you have to find the exact folder where adb.exe is located and move your TWRP recovery file there.
That's the only way I was able to get TWRP to flash to my phone.

Hi! I'm looking for ways to unlock the bootloader of my verizon's M9. Have been searching here but yet to find any success. Seeing your comment here, i thought you might be able to direct me to a useful thread. Thanks.

Adb recognizes devices during phone on state, but not in fastboot.

Okay so now that I've scanned pretty much all of what the internet has to offer on this issue, I'm helpless and forced to write a new thread here about this.
Yes, a similar question has been replied to a million times before, but absolutely none of that helped, made no difference whatsoever.
So earlier, I was on the stock rom, with TWRP flashed and root access. But wanted to switch to the community build. Tried the twrp trick to install the CB but that didn't work, so flashed the stock OP3 rom and flashed community build.
All went fine, until I tried flashing back TWRP. Used the traditional ADB method of doing that, seemed to have flashed it but tried going into recovery only to be presented with a black screen. I got fed up of that trying to fix it for a whole day so I just left it, because I could still boot into the OS and that worked fine.
Fast forward to about a week later; somehow the flash didn't work and I still have stock recovery. Now I try flashing TWRP again, but I discover that my device doesn't get detected in fastboot. It absolutely refuses to.
It DOES, however, gets detected in the OS just fine.
I've tried every which way, absolutely NOTHING seems to work AT ALL.
- OEM unlocking is checked, if that makes a difference
- USB debugging is turned on
- Uninstalled all USB drivers related to the device, and installed them via device manager (but it gave me this error:
"the folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with windows for x64-based systems)
seeing as I'm on an x64 version of Windows (its worked before with my Nexus 5, I swear)
- Tried it with different adb fastboot files, from all over the internet. All of them show just that blank space after I type in 'adb devices'
- Installed universal adb drivers.
- Samsung drivers.
- Obviously the official OnePlus drivers.
- Used Usbdeview to uninstall / force stop and re-installed the drivers.
- All in one tool
Now I'm thinking, I should try to re-lock the bootloader and unlock it again, or do like hard rest sort of things. I have no idea though, how this would affect the detection in fastboot.
Anyone have any ideas? Because I'm out of all of them, and so is most of internet.
TL;DR - Adb devices detects phone while booted in OS, but not in fastboot. Tried all methods, nothing works. Going to do lock bootloader then unlock it and try again, if not that then going to do a clean wipe and install the community build again, hoping that would work. Should I?

Hmmm Windows 7.
I can most certainly try that but the real question now is; how the hell did it work previously on my Windows 10 machine and refuses to work now? But at least I have a solution to try out, in the mean time! Thanks!

You need modified twrp by @eng.sdk.

I am having a similar issue. I have a brand new OP3. Everything stock. I'm attempting to unlock the bootloader and have found that while ADB recognises the phone, Fastboot doesn't. I'm pretty sure it's a driver issue and I have no idea how to fix.

Hello
Everything is working good
it seems to be a problem with adb Windows 10 IDK
, it is better to do it on Windows 7

I'm afraid you've missed the point, my friend.
If the phone does not get detected in the fastboot, it means I cannot flash anything, period. No original TWRP, no modified TWRP.

I had this exact issue and fixed it.
Fastboot would never see my device, no matter which driver package I tried or no matter how I tried to install or force the correct drivers. Turns out Windows 10 (and Windows 8) has a feature that completely prevents installation of unsigned drivers, which blocks the fastboot driver. If you're seeing "Kedracom" or "Android Device" in the device manager, then your driver is NOT actually installed. This is true even if Windows doesn't throw you an error message during install, or if you appear to force the installation. Even though it looks like you're doing the install correctly, Windows just ignores your unsigned drivers.
You need to temporarily disable the security feature to permit installation of unsigned drivers. This involves invoking a special restart function. Here's the howto for Win10: http://www.howtogeek.com/167723/how-...igned-drivers/
Once you've done this, on the next reboot you can do a forced install of the unsigned fastboot drivers you downloaded for the OP3. And simply rebooting your computer restores the security feature.

It's mostly because of the windows security over unsigned drivers.. Try the above method or just the cmd way..

Help usb and fastboot not reconized

I am getting a Unknown usb device (device descriptor request failed) It keep telling me usb device not recognized while being plugged it. I have tried several things
1. another windows 10 computer worked the first time then same error as a laptop.
2. unintalled the driver and rebooted.
3. also used multiple usb ports
cant find anything after searching
pixel 2 xl 8.0 September update
rooted lastest magisk 15.3
latest twrp installed
stock kernel
recently a fresh install a few days ago because i got it to work somehow but not anymore what do i do?
adb, fastboot, and storage cannot be accessed

Try these steps:
-uninstall previous version of SDK tools from PC
-download latest SDK Tools from HERE
-have a USB 2.0 cable available
-follow these steps to verify connectivity
see if these things help
Unless there is a specific reason you're still on Sept 8.0, I'd take this chance and upgrade to lasts 8.1 factory image.

I'm just spitballing here but....
With phone plugged in, on your pc, under device manage. When you open it up do you see unknown android device? That driver may need to be updated. Also, USB debugging is on, and the option to transfer files? Is your SDK platform-tools up to date?

I forgot to mention downloaded the platform tool for both computers. I never updated because i had root and nothing new was that interested enough to start all over. I followed the steps and nothing usb debugging is on. In device manager its says Unknown usb device (device descriptor request failed). I cant transfer files or anything. I tried updating to the google driver but it said it wasnt compatible.

I haven't seen it with this phone yet, but try changing the USB mode on your phone from the notification; I've had a few phones that refuse to work in specific modes.

Have you tried a different USB-C-A cable just for the heck of it. May have to factory reset and see if that solves it.

So your driver is messed up. Did you use the driver below?
https://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip
Sent from my taimen using XDA Labs

It won't let me install the driver I get some kind of error when selecting it. I was able to get it to work after plugging it in and out. Now that I updated to 8.1 everything was fine untill I got home. Now it's doing it again. I tried 2 different cables restarted my computer and laptop and can't figure out why it was working fine before without doing anything different.

Try this:
1. Go to C:\Windows\INF
2. Find the file "wpdmtp.inf"
3. Right click the file and click 'Install'
4. Once that is done, simply plug your phone and it should work.

This definitely worked for me -- Thanks for posting!

I am having sort of the same problem. I was on Android 11 on my 2xl, rooted with fast boot boot twrp.Img and installed magisk and super super, all latest. I could not get gaps so I used Android flash tool to attempt to go back stock and it downloaded and flashed it but it is now stuck in loop, I reboot to recovery and it’s stock now and it will not be recognized by adb or fast boot,!0plesase help

Bricked already, Access to Fastboot. EDL Mode Seemingly Inaccessible.

I hadn't tried rooting my phone until recently since I didn't trust myself, should have gone with my gut and waited longer since this is the only half decent phone I've got. I tried flashing mauronofrio's magisk patched boot image for 10.0.3 without realizing my phone had updated to 10.0.5. I didn't think to fastboot boot because it's been so long since I've rooted a phone. Afterwards, all of my network protocols such as wifi and mobile data no longer worked and although I could text, I could not call or receive calls. So, in an attempt to fix the issue, I used the experimental TWRP via fastboot boot in order to flash 10.0.3 since I could not find a boot image for 10.0.5 which didn't work. Then, I stumbled upon this post and downloaded the pre-compiled files with which to flash the stock fastboot roms. Obviously, I was very upset with myself for failing to read and process this information thoroughly enough and for that very reason I ended up making a far more rash decision in order to repair this issue. I ran the flash-all bat once with no difference, and a second time to get stuck in a bootloop. I have access to fastboot and the stock recovery, I can fastboot flash still, but I haven't been able to come up with a solution. If I did, I wouldn't trust myself to carry it out without confirmation from someone else. Anyone feeling generous enough to help?

I had a similar, but not as terrible experience when first attempting to get root on the 7T using the patched boot images that you used. I tried several other patched boot images, but none of them would allow the device to boot. I downloaded the full update of 10.0.5, then extracted the boot.img and it allowed me to boot the device again. Then I patched it in Magisk Manager, and everything went fine and I have root. If you have fastboot access, you can try booting your device using these images with the command fastboot boot boot.img or fastboot boot magisk_patched.img to see if your device even boots up from the images. I got stuck booting from partition b at one point, and used the command fastboot getvar current-slot to see the active partition, then I used the command fastboot --set-active=a to set partition a instead. If those commands fail then you need to update to the latest adb and fastboot and the commands will work.
This is the stock boot.img for the H1905 7T update version 10.0.5:

If you have fastboot access, you can try booting your device using these images with the command fastboot boot boot.img or fastboot boot magisk_patched.img to see if your device even boots up from the images.

I've attempted both, I was still in a bootloop sadly.

I got stuck booting from partition b at one point, and used the command fastboot getvar current-slot to see the active partition, then I used the command fastboot --set-active=a to set partition a instead. If those commands fail then you need to update to the latest adb and fastboot and the commands will work.

My first try with the unbrick tool didn't even sense my phone. I saw the FAQ and then tried to find the Qualcomm drivers in my device manager to no avail, although I did find Kedacom drivers which I could not even attempt to flash over since Windows told me that the driver I was trying to push was out of date. Here is my original post on that thread:

I see neither QDLOADER 9008 nor QHUSB_BULK in my device manager and my device is not detected by the MSMDownloadTool. I do see, however, a Kedacom USB device in my device manager titled "Android Bootloader Interface". I just want to be sure that I should download the driver you provided onto my phone before I brick it any further.

As you can see, I did not yet mention that I still tried pushing the driver since I haven't had a reply yet. I don't want to double-post there but I'm getting no luck elsewhere. I really want this tool to work, is there some way to force push these drivers or is that a bad idea? If it is, any other ideas?
EDIT: Nevermind. I think it's bricked pretty good, I'll probably have to give up on this. When I plug it in, it only goes to bootloader, doesn't boot into recovery, system, or even show the battery percentage when charging. Bootloader hasn't been giving me many options either since the commands I've tried aren't going through. Updating ADB right now, don't know if it's likely that it's causing issues right after I already updated it.

Yeah, tried it again for good measure. Is there any chance I could get this issue resolved spending less than $100 by sending it to a OnePlus repair center or elsewhere? I'm not sure they do software repairs such as this, I didn't purchase a warranty since I figured I'd root this phone and I no longer know my IMEI since I can't access the phone to check.

Ive never sent my devices in for service so Im not sure about that. The fact that you have access to fastboot still though makes me think that you arent totally screwed yet. When I had stuff go wrong and I went to use to MSM tool, I didnt have the proper drivers installed, and my device never showed up in device manager. After installing a different set of drivers and rebooting my pc, the device showed up in device manager under the Ports section. I was able to get back into my device without the unbrick tool by switching the active partition. Did you say you already checked your active partition with command fastboot getvar current-slot? If you are on slot a, have you tried setting slot b as the active and seeing what happens? This is the command fastboot --set-active=b.
Here is a driver for the unbrick tool to recognize your device that might work for you. https://www.dropbox.com/s/lgt1qanfqs8pvbe/QDLoader HS-USB Driver_64bit_Setup.zip?dl=0

I did try setting the active partition to slot b as well, I was getting pretty much the same errors as attempting to boot from an image file. Although, I just now tried setting the partition to b and it worked. I'll try rebooting the phone to partition b now as well.
EDIT: Thankfully, setting the partition to slot b worked! My phone now has access to system and recovery once again and boots as normal. I am still in a bootloop though, so I'm attempting to install the drivers now.

Awesome, installing those drivers right now. The link provided in the beginning of the thread for the MSM Tool just wouldn't work for me since my device was detected as something that wasn't mentioned in the entirety of the thread so I couldn't install it directly via device manager as directed. This should hopefully get me up and running on the tool, I'll update this post once the drivers are installed hopefully.
EDIT: I installed the driver but nothing has changed from before. The MSM tool still doesn't detect my phone, I made sure it was run as Administrator. My device drivers are still Kedacom which I attempted to update the driver using a file on my computer once again and Windows wouldn't allow it. Am I simply looking in the wrong place to manually install this driver? My device manager is set to view devices by type and plugging in my phone causes only the Kedacom USB device to appear, so I assume I don't have QDLOADER 9008 or QHUSB_BULK devices listed there. I can provide screenshots of my device manager window if it helps.

Hooray! Almost haha! It is the worst feeling when you mess up your brand new device, but as long as I have fastboot I dont stop trying to fix my mistakes. You should be able to fix it for sure.

On my pc, I didnt have any issues with the drivers, but when I was helping a friend over TeamViewer trying to do the same thing you are trying to do, the drivers just didnt help no matter what and it wasnt listed in the device manager. I was able to make it show properly on his pc by using the steps explained in this article. https://docs.microsoft.com/en-us/wi...boot-configuration-option?redirectedfrom=MSDN After restarting his pc, the device showed up properly in device manager with test mode enabled.
Are you able to access adb now, or still only fastboot?

I embarrassingly don't even really remember all the specifics about how ADB works, although I don't think I have access since I'm in a bootloop when I launch Android. Unless I have access to ADB via fastboot or recovery, I don't think I do.

Yeah I had no idea what Windows test mode was. Before I rebooted just now to install the drivers you provided, I actually launched into Windows test mode with no command from me telling Windows to. I thought Windows invalidated my license yet again tbh, glad to know it didn't. I don't think I'm in test mode now, so I'm giving that a go right now. My computer takes a while to warm up so I'll let you know the results in a bit.

It will just make driver installing issues less likely. When you boot your phone, what happens on the screen? Does it get stuck on a certain screen or just restart over and over? You can see if adb can see your device with the command adb devices, and it should list your device. If not, try fastboot devices and it should be listed. You need to put the device into EDL mode for the unbrick tool to work, and for it to be shown in device manager. My friends device manager listed Kedacom just like yours, and I didnt do anything to that at all. I just used test mode, installed the Qualcomm drivers, put the phone into EDL mode and the unbrick tool should recognize it. If your phone is listed when you type adb devices, you can use command adb reboot edl to enter that mode needed for the unbrick tool.

Sadly my drivers haven't changed. I uninstalled and reinstalled the installation file you gave me since I first installed it via WWAN-DHCP instead of ETHERNET_DHCP. I use a VPN so I figured that may have affected the installation, although for some reason I didn't think to just turn off the VPN when I reinstalled. Regardless, I don't think my VPN or the way I installed the driver is the cause of the drivers mentioned not being found in my device manager, so I'm likely not going to bother.

Another problem that can cause your phone to not show up in device manager is the usb port you are using. Have you tried any other ports? Are you able to shut your phone all the way off by holding power until it turns off? If you can unplug the phone and turn it off, then hold the volume up and volume down buttons together, then plug the cable back into the phone and it should put it into EDL mode.

I seem to have been missing a vital part of information. I don't know why the term "EDL" just went over my head, I probably just associated it was fastboot mode when I looked it up. How do I get into EDL mode? Is it safe to assume the method listed here works for the OnePlus 7T?

Fastboot mode and EDL mode are two different things. I have never used the fastboot to EDL method, but I have read about it and I assume it should work atleast on some devices. Unplugging from pc and turning the phone off, then holding both volume buttons and then plugging the cord into the device should enter EDL mode without commands.

I must have assumed that it was fastboot mode since when I held those buttons and plugged it in, I'd always launch into fastboot mode. Perhaps it's different with the US version? That's the version I have.

The only version I have used at all is the US one. You could try holding both volume buttons for a few seconds before plugging the cable into the phone, but if that doesnt work you can try the fastboot to edl method. I have no experience with it at all though so I dont know if it works with this device or not, but you would just open the edl.cmd file and it should put the phone into edl mode.

It just boots me into Android sadly. I don't know that there's any way to get into EDL mode for me. Possibly due to my use of the experimental TWRP and mauronofrio's Stock Fastboot ROM tool.
