Fastboot, waiting for device.

Hi guys, I recantly decided to update my gt540 from 2.1 to 2.3.3
I followed steps by steps on by this tutorial - http://fdapps.comuf.com/downloads/The LG GT540 Optimus reference page.pdf
Installed rom with fastboot, tried to install Clockwork with fastboot, I typed fastboot flash recovery C:\recovery.img , and then there's <waiting for device> , doesn't go further, I have everything installed sdk, usb drivers and usb debugging activated. Maybe there's some problem with key combination, to get in fastboot. From google I understood, that I have to turn phone off, then press and hold camera + press power button! I did other combinations too, but didnt work.
Just waiting for device..
Any ideas? I read, that if you're in fastboot there's just a black screen, and on pc desktop appears fastboot usb. I have non of that.
Thanks for help in advance.

fastboot "waiting for device"
I have installed all the drivers and everything is working fine except fastboot. I have "nexus s" with me. The problem is:
I do "adb reboot bootloader" to flash the images, but after that if I do "fastboot devices", it doesnot show my device and if I do "fastboot flash ..", it just displays "waiting for device".
Can any one please help, I need it urgently..
THanks in advance

501CG Can't mount /cache/recovery/log ... etc

My 501CG is in a bootloop and can't go to recovery.
The device can be detected by adb but I can't sideload anything. I've tried everything I know but couldn't fix it.
I tried to post a screenshot but the forum won't allow me and I can't explain what the problem looks like so I don't know what to do now...
Please help me. Thank you.

Can you go to fastboot? Adb still reconize it then go to ADB and type adb reboot bootloader then try to flash the recovery and factory reset. If the problem still exist after factory reset you will need to look up for system.imgs files for the zenfone 5 and flash the system imgs from fastboot

Thank you so much for helping me.
When I type adb reboot bootloader, it says <waiting for device> and stays that way.
I have a screenshot of the error but I can't post the proper link. Here's a modified version of the link, just replace the <dot> with a period I guess if that would work. That's the only way I can show what happens to the phone.

Sorry, I'm also not very familiar with how adb, fastboot, and whatever else works, but I learn fast and can follow commands.

Well the mmcblk1 partition i think is messed up @dgadelha can you help us with this?

Hey there!
Thanks @ChristopherXI for noticing me.
@Teks0427, can you please try this guide? It will rebuild your partition table and install Android 4.3.
Hope it helps!

Well. Did it work? Have any luck?

I'm so sorry for disappearing all of a sudden like that. I had to attend to a LOT of things and I totally forgot about the phone.
I'm gonna give it a go tonight and post whatever happens here right away.
Thanks guys! I really appreciate the help...

Hi! The phone won't go to droidboot mode. PressingPOWER + VOLUME UP brings me to the Asus bootup screen (sometimes with a black background and sometimes with a blue one) and the words
CSC Mode
long press power key to restart system
And sometimes it's just the normal Asus bootup screen (and gets stuck there). On that CSC mode screen, plugging in the USB and typing "fastboot devices" does nothing
D:\501KL>fastboot devices
Booting up in recovery mode works, and when in the recovery mode menu page, typing "fastboot devices" still does nothing but typing adb devices gets this response:
D:\501KL>adb devices
List of devices attached
051c7013 recovery
D:\501KL>
Running (as administrator) the file sec_offline_update_image.cmd from the recovery menu page gets this response:
D:\501KL>fastboot oem backup_config
< waiting for device >
And it stops there.
Also, when plugging the USB cable to the phone, it starts installing an "MTP USB Device" but always fails after a few minutes.
I already tried bringing the phone to the accredited Asus Zenfone repair center here in the Philippines but they said they don't have the firmware to flash this model. They didn't give any explanation nor did they refer me to anyone else who might know how to fix this thing.

Read his problem carefully.
He has a 500KL not a 500CG.
That guide will not work
Apologies for saying thus but if there are no RAW firmware of the LTE model. It's pretty hopeless

The sec_offline_update_image is for A500CG/A501CG only.
I'm sorry but I do not own an A501KL so I can't help you with that.
And if ASUS can't help you, sue them for that.

Bro You Should change your """Title:501CG Can't mount /cache/recovery/log ... etc"""

Yes, I'm so sorry. I noticed the error in the title just now. I got confused with my 2 Asus phones that I put the wrong model in the title. Stupid stupid me...
I'm so sorry for the mess.
Thank you all for your help...

I guess it will help you...

Getting your device connected is a very important stage, whether it is system,recovery or fastboot. From what I read , you can connsct through fasatboot, since you flashed cyanogen. Just flash TWRP 3.2.1 or so which is the latest, through fastboot:
fastboot flash recovery twrp.3.2.1 .img ( Remember the spaces, the name twrp.xxx.img should be same as you downloaded. If flash is successful, you can see twrp when you boot to recovery. Then flash supersu file and/or whichever rom you want.

Sorry for late answers.
I was lil busy and sorry for wrong address also.
You could get it from firmwarefile.com
I can't post link here but select yu yureka plus variant and download oldest CBP

Fastboot mode issue in MiA1

Hi.
Recently I decided to flash lineage os 15.1 on my MiA1
For that I have downgrade to Android nougat.
After downgrading I booted my device.
After setting up device I booted device in fastboot mode to follow further steps like flashing TWRP and all but the problem is my device goes in fastboot mode and it is not identified by abd and after that it is automatically getting restarted and is not holding in fastboot mode.
Please help??

Odd issue. What are you using to flash? If you are using XiaoMiFlash.exe, you'll want to try the (THIS WILL REMOVE ALL YOUR DATA) "clean all" option. Please note that this removes all your data.

I have used MiFlash tool for this and now My device automatically reboot from fastboot mode so I am not able to use adb as well to flash rom or twrp also Now MiFlash tool is not recognising the device.

Hmm. What ROM version are you trying to flash on this? If your device isn't recognized by your PC when in fastboot mode, I'm not sure how you'd flash it.

It should boot if you've fully flashed it and cleaned the user data partition. If it still isn't, you'll want to wait for other members with more experience in bricks to chime in.

My device is booting up without any problems.
But the problem is bootloader is still unlocked. So i am not able to update via OTA.
And as the device does not holds in fastboot mode so I am not able to do other flash work.
Is there any way I can share a video of my problem with you?

Oh. If it's booting up fine, then you shouldn't be worried too much.
If it keeps restarting in Fastboot mode, it could be a driver issue which is preventing your PC from recognizing your device and vice versa. I'm on Windows 10 which installs drivers automatically so I've never had experience with it.

Please see this video.
If i boot in fastboot mode the device should be in fastboot mode till power button is not pressed for at least 10 seconds.
But in this case it gets switched off.
I have not connected the USB to pc and nothing else.

But in this case it gets switched off.
I have not connected the USB to pc and nothing else.

I think that's expected behavior? If it doesn't recognize itself being connected to a device, it'll exit fastboot mode.
I think you need to connect it to the USB cable and into your PC for it to not restart/power off.

No when I connect it to pc at that time also same happens.
Previously when booted in fastboot mode it will stay ther by the time juice is out.

So do you know how can I help myself out?

wait.. what exacly did you do when you booted into fastboot? did you type "adb devices" or "fastboot devices"? also, try rebooting into fastboot mode by typing "adb reboot bootloader" in cmd, with your phone plugged into your pc, and with the proper platform-tools installed. it shouldn't really go away from fastboot mode like that.

Hy man, I know basic of adb and I use cmd "adb devices"
My device is recognised when it is on.
I can also give various cmd like boot in recovery or fastboot mode or reboot and the device follow the instructions.
Please see the video that I've shared.
Once fastboot mode is on the device is automatically restarted in about 10 to 15 sec and within this time MiFlash tool or adb cmd prompt bot does not recognise my device.
I have tried to flash OTA via adb side load but it is showing error.
Help me with your input!

Your device doesn't get detected in your CMD prompt when it's in fastboot AND you type "fastboot devices"?
If it doesnt then you might have flashed something incorrectly.
Also, make sure to have your android drivers up to date in your pc. It's very, very likely that you don't have them installed on your PC, or they are outdated. See this: https://developer.android.com/studio/run/oem-usb.html

I have faced this issue. Yesterday i dirty flashed a custom rom. but i forgot how to dirty flash. i just simply flashed the rom and restarted the phone. it was mandatory to flash custom recovery and gapps after flashing a rom dirtily or normally. but i didn't. After the reboot completed, i remembered that i didn't flashed the twrp and gapps. So, i go back recovery mod, guessed i could flash twrp now. But i didn't see any custom recovery on my phone. But the phone boots, and i can use the phone. Still, i'm on that phone, while i'm typing this comment. i didn't lost my data cause i flashed dirtily. But the problem is, as i didn't flashed gapps or magisk (for root access), now i can't use google apps like, play store, and more. As i don't have root access on my phone so, i can't run flasify, to flash custom recovery. neither i can run other apps that need root. As i didn't flash custom recovery, now i can't flash gapps, magisk and whatever that needs a custom recovery.
I told some rom porter about the matter. They told me to flash stock rom. So, i was trying to flash stock rom. but flashing stock rom requires a fastboot mode. But my fastboot logo doesn't appear and it's blank. I told this to a rom porter. But he said, He doesn't know about that and he can't help.

The system has been destroyed please help

So I flashed the stock pie rom from this forum, came from pixel experience 9. After I flashed the ROM I also flashed the twrp installer and when I rebooted it says the system has been destroyed and press the power button to shut down. I can boot the phone in fastboot but it doesn't recognise it even though the drivers are installed and it worked perfectly before. The miflash program also doesn't recognise anything after I press refresh.
Is there anything I can do?

Boot into TWRP (by booting not flashing) and get a flashable rom with twrp for ex. https://forum.xda-developers.com/mi-a1/development/twrp-stock-8-1-0-t3856328

You have to boot to twrp from the bootloder screen.
Use this recovery to boot from pc and never Flash twrp on pie.

Yes, I also have a redmi note 5 Pro and a mipad 4 and both work well with ADB.

Try flashint stock on EDL mode.

Same error with me today. Tried to restart 5 times. Its unbelievable but the fix was very easy. Just run "fastboot continue" and wait for 2 minutes for a working reboot!

Thanks for the Solution

Thanks for the solution. Worked for me as well for similar problem. A simplified step by step if anyone still couldn't get it to work.
Power off your phone as asked by the Error Message
Press Volume Down + Power button simultaneously to boot into fastboot.
Load Command Prompt in the ADB/Fastboot folder in your PC (ADB and other drivers need to be installed)
Type "fastboot continue" and press enter
And you are done. If your phone is not recognized by the PC (after you put it to fastboot mode) make sure you have proper Drivers installed for your devices. You can use MiFlashTools to install required drivers automatically.

Thanks for this. This happened to me two weeks ago, had to completely flash stock rom and begin from zero. Hopefully others will see this and avoid starting fresh.
