Hello,
I have followed a tutorial for solving the problem of "Fastboot mode started
udc_start()" from this thread http://forum.xda-developers.com/showthread.php?t=2131247 and something was go wrong.
I have done this steps in the sdk platform tools folder:
1- fastboot erase recovery
2- fastboot flash recovery recovery.img ( here i've got an error)
3- fastboot reboot
Everyting was ok until I have tried to write the .img file on the phone. I've got an error that I don't have enough space. I think I have deleted the recovery file and now it's stuck, because it's not booting. The 4 leds from the bottom it's flashing continuously and the screen remains to the LG logo. I have tried to connect the phone to the PC but the device it's not recognized anymore. I get this message in the adb tool "Waiting for device"
I really appreciate if it's someone that can help me
I have a p500 and I had the exact same problem as you. But I was able to fix it after a lot of Googling.
Can you get to fastboot right now? If so, make sure that the recovery you downloaded is correctly named "recovery.img" and is placed in the same folder as adb.exe is located. After that, type:
Code:
fastboot devices
into ADB. If your device is listed then proceed and type:
Code:
fastboot flash recovery recovery.img
If nothing comes up when you ask it to list fastboot devices you need to delete all of the drivers associated with your p350, and then reinstall them using a toolkit or PDAnet. Then go back and try fastboot devices again.

No, I can't get to fastboot. I can't do anything with the command line. It remains to the logo screen

Can you pull the battery and then use the combination to get into Fastboot? If you can't get to fastboot, then the problem is beyond what I'm capable of doing.
Though, the problem may be that you completely deleted your recovery.

That is incorrect. The recovery does NOT have to be named recovery to use fastboot to flash it, although it does make life simpler
So I had an old Nexus 5 running a custom KK rom. I tried getting it back to stock using Wugs Toolkit. I've been playing with it for hours trying to get it to work. I ended up making it worse and it gets stuck on Google Logo now. I tried using the revert to stock option on the toolkit. It looks like everything is working.. Here is the log..
Connectivity Status: Fastboot Device Connected
+ Confirmed: Bootloader Unlocked.
fastboot getvar product
product: hammerhead
finished. total time: 0.001s
Launching flashstock.bat
and then it just stops.. I tried downloaded two seperate .tgz images from Google. They both do the same thing. It doesn't go out of the bootloader screen or anything. It writes the radios and that's about it.
This is a *very* high-level suggestion - there are many tutorials that take you through drivers/ADB, etc. I just want to give you the script I followed for the manual procedure, which turned out to be extremely quick and simple.
After suggesting Wugfresh's NRT to several people in these forums (I'm a very big fan) I decided to refresh my Nexus 6 with the latest image and make it unencrypted - a problem that doesn't exist on the N5. I wasn't sure that NRT would do this for me, since the script automatically restarts the device and I wanted to be sure that it didn't start before I had flashed a modified no-encrypt boot image, since it would just encrypt itself again. So I downloaded the factory image, a no-encrypt boot image (thanks, doitright ) and TWRP - naturally being very careful to get the right ones. I unzipped the TGZ and the image files down to their final *.img components. To make things simple I renamed the various images to one-word names (e.g. radio.img). I put all of them in the same directory as ADB & fastboot.
Since all Nexus devices are updated the same, this should also work for you. Since you've used NRT I'm guessing that you have the PC drivers already installed. You'll also need ADB/Fastboot. Switch on USB debugging, connect the N5 to your PC, and in a CMD window type these commands:
fastboot reboot-bootloader
fastboot flash radio radio.img
fastboot reboot-bootloader
fastboot flash recovery twrp.img
fastboot flash boot boot.img
fastboot reboot-bootloader
fastboot erase userdata
fastboot flash userdata userdata.img
fastboot -w flash system system.img
fastboot flash cache cache.img
fastboot reboot
Some of these may be overkill (I believe the -w wipe command erases userdata anyway), but it worked for me.
I would say take a TWRP image first as well so that you can recover, but it sounds as if you have nothing to recover anyway.
If the more expert member want to suggest amendments to the script, I won't be insulted...

USB debugging means nothing if you're trying to use fastboot.

Hey, sure, I didn't mean to "attack" you. I noticed that you wanted to help. Really. Thanked you for that.
No worries, beekay. Posts don't allways mean what they look like, which is why we have smilies.
And I did read the articles. I tried with my N6 to attach it in bootloader mode with no USB debugging, and you're absolutely right. I suppose I just read "Remember to switch on USB debugging" so often that I assumed it was needed for any sort of work. Thanks for the tip. It's things like this that encourage all of us to try new things - like flashing a ROM manually instead of with NRT...
This problem occurred to me when I updated Wugfresh NRT to 2.0.6.
So I return back to 2.0.5 and this problem solved.
Try using NRT 2.0.5 to see if the problem solved or not

Ran "fastboot flash boot twrp.img" instead of "fastboot boot twrp.img"
When trying install TWRP for the first time on a new (to me) Pixel 3, after unlocking the bootloader I ran "fastboot flash boot twrp.img" instead of "fastboot boot twrp.img". Can still enter the bootloader, but anything else gives a black screen.
What is the best method to recover from this? I still have access while in the bootloader through fastboot. Should I reflash stock google images or is something else better to recover? If I should reflash the stock google images what is the best method to do so?
Yes after reading more I realize this was the wrong thing to do. "fastboot boot twrp.img" was not working so I figured to try flashing instead, but afterwards realized that was obviously wrong.
Thanks for any help.
OK, It looks that I am soft bricked and a factory image reset is the only way to recover.
The steps I've seen mostly commonly referenced are to run the following
Code:
fastboot erase system_a
fastboot erase system_b
fastboot erase boot_a
fastboot erase boot_b
fastboot reboot-bootloader
flash-all.bat (using the factory images)
The issue seems to be that Android 10 which was on the phone doesn't work with fastboot erase. Is it necessary to run this or is it OK to go straight to flash-all.bat? (BTW I finally figured out that my issue above was TRWP doesn't support android 10 yet, but the guides I saw were older and didn't mention that. )

First things first. TWRP does not work at all on a Pixel with Android 10. Flash-all should be all you need to do to recover from your issue.

The 3 top guides from google all had steps for android 9 apparently and so I didn't catch that 10 is different..... flash-all.sh worked and we're back. Thanks!
I've got a BIG problem with my new Pixel 5. I've successfully rooted it and had it operating for a day.
I then decided to boot into recovery mode just to see what the new stock recovery looks like (I used to use TWRP.).
BIG MISTAKE!
All I got was the error icon that I've seen in the past meaning that no recovery image is available. OK, so I try to just try to do a simple reboot. I'm taken back to the same place.
Now I try to reload Android. No luck! I'm stuck on:
"Device product is 'unknown'"
Update requires 'bramble'.
HELP!!!!
In the file android-info.txt, what would happen if I patched the line
require board=bramble
to
require board=unknown
Did you figure this out? I'm facing the same issue with my Pixel 5.
Edit: I figured it out. If you are having an issue with the 'flash-all.bat' command like we were, you just need to manually push the individual files and it should boot you back up into stock.
Run these commands:
1. fastboot flash bootloader <bootloader image file>
2. fastboot reboot-bootloader
3. fastboot flash radio <radio image file>.img
4. fastboot reboot-bootloader
5. fastboot update <image zip file>.zip
6. fastboot reboot
All of the reboot-bootloader commands may be redundant but it worked for me. It booted me into stock, verified I was unrooted with Root Checker, then proceeded to reboot back into the bootloader and 'fastboot flashing lock' to re-lock my bootloader and wipe the device.
I am having issues booting into my unofficial TWRP installation on my Moto g stylus 5g after attempting to install an unofficial modded LineageOS image.
My problem: I try to boot into TWRP through the command line on my computer using
Code:
fastboot boot twrp-boot.img
, but my new phone disconnects from my computer before the command can finish. Though TWRP is already installed and I can access it by entering recovery mode without my phone needing to be connected to my computer, the touchscreen on the installation does not work. The touchscreen only works if I use the
Code:
fastboot boot twrp-boot.img
command.
My drivers are the latest version: 33.0.3.
I unlocked the bootloader. To do this, I:
Tapped on the build number to become a developer.
Enabled OEM unlocking and USB debugging.
Unlocked my bootloader.
I installed TWRP recovery. To to this, I:
Downloaded the unofficial TWRP image linked in the first paragraph, as well as the Magisk ZIP.
Ran
Code:
fastboot boot twrp-boot.img
while in bootloader.
Copied the image and the Magisk ZIP from my computer to my phone.
Installed TWRP using "Install Recovery Ramdisk".
Installed Magisk.
I attempted to install LineageOS. To do this, I:
Downloaded OTA ZIP, copy partitions ZIP, and boot image from the LineageOS thread linked in the first paragraph.
Flash booted the boot image.
Selected ADB Sideload mode in Lineage recovery.
Ran
Code:
adb sideload copy-partitions-20210323_1922.zip
and
Code:
adb sideload LineageOS-Modded-19.1-Osaka-V2-OTA.zip
on my computer.
I attempted to re-access TWRP recovery, after Lineage recovery seemed to replace it. To do this, I:
Ran
Code:
fastboot boot twrp-boot.img
while in bootloader.
Installed TWRP using a different method than the previous installation (maybe "Install using this image") because I couldn't copy the installation files to my phone as my phone was no longer writable.
After I rebooted I could no longer use the touchscreen to navigate TWRP. That is, until I figured out
Code:
fastboot boot twrp-boot.img
worked. But after I attempted to enter ADB Sideload mode using TWRP and install one of the ZIP files I needed to install for LineageOS (
Code:
copy-partitions-20210323_1922.zip
), my phone began periodically turning black and disconnecting from my computer, again.
It had been turning black, disconnecting, then turning back on and reconnecting on a regular interval while I was trying to unlock the bootloader. I almost made a post about it. When I tried one more time, just to get the error message I could copy and paste, the command I had been trying to run ran fast enough and it worked. What I had done differently that time was I ran the command right away, without running
Code:
fastboot devices
.
After a while the phone stopped disconnecting periodically. After I installed one ZIP, it started again.
How can I get my phone to stop periodically disconnecting from my computer? How can I access TWRP again?

First of all, the command that you tried to use is not even the correct command for fastboot booting TWRP(unless your TWRP file is named "twrp-boot.img" and if the file is stored in your fastboot folder on PC). The correct command is:
fastboot boot twrp.img
The command you typed isn't even an actual command, that I know of. The command you typed is trying to tell fastboot to tell TWRP to boot a boot.img, which, makes no sense at all and isn't how it is done.
There is:
fastboot boot twrp.img
And
fastboot boot boot.img
As far as I know, there is no such thing as:
fastboot boot twrp-boot.img
The way fastboot commands typically work is:
fastboot <what you want fastboot to do> <what you want it to do it to>
In your case, you want to use fastboot command, so, you type: fastboot
You want it to boot a .img, so, you follow that with: boot
You want it to boot a twrp.img, so, you follow that with: twrp.img
If you put that all together in one command, you get:
fastboot boot twrp.img
This command is typically used to boot(not flash) a live TWRP session on devices that have locked bootloader because they can't actually flash TWRP "onto" their device with a locked bootloader. This command would probably actually boot your twrp.img if it is stored in your fastboot folder on PC and if the file is actually named "twrp.img"(you can rename it to "twrp.img" if it isn't). But, it wouldn't be booting the TWRP that is installed in the recovery partition on your device, it would be booting a live TWRP directly from the TWRP file in your fastboot folder. In other words, it boots on your device "from" your PC "onto" the device without flashing it, instead of booting on your device from the recovery partition on your device.
If you wanted to flash the twrp.img, the command would be:
fastboot flash recovery twrp.img
Fastboot followed by what you want fastboot to do(flash recovery) followed by what you want it to do it to(twrp.img).
But, all of that is beside the point because you say you already have TWRP installed. If you already have TWRP installed on your device, you don't need to use the "fastboot boot twrp.img" command line. You should be using adb, with this adb command:
adb reboot recovery
This adb command that I posted is used to boot into TWRP on devices that already have it installed. It is also used to boot into stock recovery if stock recovery installed. In other words, it boots yo whatever recovery you have.
Hopefully, you understood all of that without my wording confusing you.

Hello. Thank you for responding. "twrp-boot.img" is just the name of the file on my computer. I changed it to "twrp.img".
I know I don't have to boot a live TWRP session from an image when it is already installed. However, whenever I try to use the TWRP I already installed, I cannot press anything becaue the touchsceen doesn't work. When I boot from live, that touchscreen works. It would be good to know how to fix the touchscreen on the installed version, but I'm willing to make do with booting from live if that is possible.
When I use "fastboot boot twrp.img" after renaming the file (it gave me a "no such file or directory" error before renaming the file), I still have the problem where it loads for a few seconds, then my device does black and disconnects from my computer, then soon goes bright and reconnects to my computer. This is what this looks like in the command line:
fastboot boot twrp.img
Sending 'boot.img' (98304 KB) FAILED (Status read failed (No such device))
fastboot: error: Command failed
Now it is not as though my device was never connected. I can use "fastboot devices" to verify it is connected when the screen isn't black. Also, the output looks different when my phone isn't connected at all:
fastboot boot twrp.img
< waiting for any device >
In one instace, the phone is connected and then disconnects. In the other instance, it is never connected.
My phone disconnects from and reconnects to my computer periodically. That is, roughly every 33-34 seonds. It reconnects quickly without my input (roughly every 4.5 seconds). I used a stopwatch to make sure of this.
Spoiler: Stopwatch Times
Connected (in seconds): 29.22, 34.11, 33.84, 34.03, 34.02, 33.75, 34.04, 34.05, 33.73, 33.93, 33.73
Disconnected: 4.28, 4.45, 4.50, 4.53, 4.51, 4.50, 4.48, 4.80, 4.50, 4.80, 4.60
I tested using "fastboot boot twrp.img" at the beginning of a connected interval. The command ran for the whole 33-34 seconds before the phone disconnected and it gave me that same error. I don't think that command took so long to execute when my phone wasn't turning black periodically. I can run other commands like "fastboot devices".
When my phone isn't connected to my computer, it doesn't turn black every 33-34 seconds.
Entering "adb reboot recovery" produces this error:
adb reboot recovery
error: no devices/emulators found
"adb devices" shows no devices attached. That has always been the case when running adb commands in the bootloader. I can run them when my phone is turned on normally (there is no OS so I can't do that now).
Thank you for your advice. Do you know anything about the phone disconnecting?

I tested using "fastboot boot twrp.img" at the beginning of a connected interval. The command ran for the whole 33-34 seconds before the phone disconnected and it gave me that same error. I don't think that command took so long to execute when my phone wasn't turning black periodically. I can run other commands like "fastboot devices".
When my phone isn't connected to my computer, it doesn't turn black every 33-34 seconds.
Entering "adb reboot recovery" produces this error:
adb reboot recovery
error: no devices/emulators found
"adb devices" shows no devices attached. That has always been the case when running adb commands in the bootloader. I can run them when my phone is turned on normally (there is no OS so I can't do that now).
Thank you for your advice. Do you know anything about the phone disconnecting?

Try this, type:
fastboot devices
Then type:
fastboot reboot recovery
Or
If your device has a bootloader mode, try this, type:
fastboot devices
When it returns the serial number, type:
fastboot reboot bootloader
If you have a bootloader mode/menu, it should boot to that, then either select "reboot recovery" or type:
adb reboot recovery
Or
fastboot reboot recovery
ADB may or may not work in bootloader mode, if you have it.
Are you certain that your bootloader is unlocked and are you certain that you correctly flashed TWRP recovery to the correct partition and that the TWRP.img that you flashed onto the device is an actual TWRP recovery .img and not some kind of modified boot.img? I ask this because in your post above, you typed:
fastboot boot twrp.img
Then it returned
"sending "boot.img"(98304 KB) Failed"
This implies that you are using a boot.img, not a recovery.img/twrp.img. I think your file may be some kind of boot.img to be used in association with something to do with flashing/using TWRP or a boot.ing for your device that is meant to be flashed via TWRP(TWRP can flash .img files)
You can also try booting into your one-touch working TWRP, then, connect a USB hub to your android device and connect a mouse and keyboard, it should natively support the mouse and keyboard, you can use the mouse and keyboard to work inside TWRP to make selections.

Thank you. I tried doing "fastboot devices" then "fastboot reboot recovery" and "fastboot devices" worked and returned a serial number but "fastboot reboot recovery" kept running until the screen turned black and the phone disconnected from my computer. The same thing happened when I tried "fastboot devices" then "fastboot reboot bootloader".
I remember unlocking it by using I code I got from the phone to get another code I got from the Motorola website. It says "flashing_unlocked" on the screen when it hadn't before. I'm pretty sure I unlocked it unless it's supposed to say something else. I've seen another Motorola that just said "unlocked" but it wasn't the same exact device.
I am not certain I flashed TWRP to the correct partition.
I will try connecting a mouse and keyboard so I can use TWRP.
