Everything is all right. Fastboot in my p350 looks the same. Just connect your phone to USB and start using fastboot on computer.

it means that fastboot is ready to receive commands from you.

fix fastboot mode started
Fastboot mode usually comes up if something went wrong when trying to flash a recovery image, for example when flashing AmonRa recovery or ClockWorkMod. It happened to me several times so I tried to learn to revive it without reflashing the original firmware. Note: This tutorial works only if recovery is the only one broken. (If the ROM itself is broken, then that's a subject for another tut.) In this case, the most logical thing to do is just reflash the recovery image. So how do you do it in fastboot mode? Here's how:
Symptom
You tried flashing a custom recovery like ClockWorkMod or Thunderg, or you flashed an incorrect ROM, and when you rebooted, it showed this screen:
Code:
Code:
fastboot mode started
udc_start()
and the phone stays there. When you plugin the phone to your computer's USB, it is detected and the screen has this display:
Code:
Code:
fastboot mode started
udc.start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
You will need
1) Your PC and your USB cable for the phone
2) USB drivers for your phone (use B2C from LG).
3) Android SDK (download from here)
4) Java, required to run the SDK (but right now I am not sure if this is required to run fastboot!)
5) ClockWorkMod or AmonRa Recovery.
Here's what to do
1) Assuming phone is turned on in fastboot mode, plug it in to the USB of your PC. You will know that it is detected if you see the the lines "suspend", "reset" and whatnot on the phone's screen.
2) Extract the recovery image from the zipfile downloaded from step#5 above (e.g. LGp500-recovery-v12.img). Place the image file in the same folder where fastboot.exe is (usually in the tools\ folder in the SDK). For your convenience, rename the img file as recovery.img
3) Fire up your command prompt and cd to the directory where fastboot.exe is located. Then type the following command:
Code:
Code:
fastboot erase recovery
Once you get the confirmation that it was successful, type this:
Code:
Code:
fastboot flash recovery recovery.img
Once you get the success confirmation, reboot the phone, or you can also type (optional):
Code:
Code:
fastboot reboot
The phone will reboot itself, and with any luck you should be able to go back to your same old Android bootscreen. Note that no settings were modified here, so this is extremely useful for those who do not want a clean slate after a fastboot nightmare.
Also, note that if this is successful, you can now boot to recovery with the usual button-combos, thus enabling you to flash ROMs and other recovery zips.
Note: On some SDK versions, fastboot may not be included. For your convenience, I have attached the fastboot binary I got from my downloaded SDK. I have also attached AdbWinApi.dll which some user reported is missing in the SDK. Place the DLL in the same folder where fastboot.exe is located.
Questions, just drop me a line here

If someone is using Linux then all the procedure is much easier, because there is no need to install lg drivers. There is no need to install android SDK, because a dB and other tools can be installed as standalone apps without all SDK. ADB and other things are often in repositories (for example in archlinux it can be installed from AUR).

In need of Help !!!!
Hello Everyone.
I have been reading xda developers for a month now and got some some custom rom's like CM9 nightlies and CM7 nightlies.
I was using CM9 and it did have usb detection when it was released and i did not get a fix for that.
2 days ago I flashed ClockworkMod 6.0.1.3(as it was mentioned to do so before flashing the rom ) and the i flashed Gingerblur rom.
The rom started and i used to get a message "android.com.acore." failed to load. Never happened before!
So I re-flashed CM9 and it went into fastboot.
Read all the material on fastboot.
Tried "Kameshs and antdkings p350 toolkit v1.2" and further versions installed sdk but nthng works!
My pc shows "Code 10 " error in the abd interface.
I guess the usb is not getting connected to the pc properly and hence whatever i do after connecting to the pc is not helping.
In the kamesh toolkit the command dosent go forward saying "<waiting for the device>"
I hope some one can help as soon as possible!!:crying:

D855 Stuck at Boot Screen

So I think I've gone and bricked my LG G3.
After the ROM I was using, cm-13.0-20160322-NIGHTLY-d855 (CM13 March 22nd) from here, kept freezing 20 seconds after startup, I went to update to cm-13.0-20160325-NIGHTLY-d855 (CM13 March 25th). I booted into recovery (TWRP 2.8.7.0) as usual and went to flash both the ROM's .zip file and an Opengapps .zip file using TWRP's queue feature. However, it appeared to get stuck at a line (unfortunately I don't remember what it said exactly. Something involving patching system, I think), so I pulled the battery. I get the feeling this was a super not good thing to do, as my G3 now sits at the "LG - Life's Good" screen indefinitely. Holding Power+Vol.Down does not boot into Recovery, and neither does holding Vol.Up and plugging into my computer activate Download mode.
I tried to be as thorough as I could with exactly the steps I took, so I'm just hoping someone can give me a few pointers on what I can do.
As I type this I had the phone connected to my computer next to me, and I've suddenly heard the Windows "Device connected" sound and the phone is now showing this in the top right corner, in tiny font:
Code:
[784670] Fastboot mode started
[784820] -- reset --
[784820] -- portchange --
Edit: When this occurred, a device named "Android" appeared under the "Other devices" tab in Windows Device Manager. It's got a yellow warning sign next to the icon, and Properties says that the drivers for the device aren't installed.
Perhaps this is relevant to getting it working again.

First you need the adb drivers for lg g3
Then you need proper partitions, depends what your starting system was, before cm..
then simply reflash them
fastboot flash aboot aboot.img
fastboot flash recovery twrp.img (because you don´t have one)
fastboot flash laf laf.img (this should fix the download mode)
Depending on what the system in original was and what the cm package installed...

Many thanks for the reply.
By ADB drivers for the LG G3, do you mean the Lg United Mobile Driver? I have version 3.13.2 of them, if that's what they are.
When I input the commands
Code:
adb devices
or
Code:
fastboot devices
nothing appears, so are there different drivers I should look for?
I'm not too sure how to "fix" partitions, either, but I'm guessing it requires ADB/fastboot.
The file aboot.img and laf.img, will I need to find somewhere to download them from?
Again, I appreciate the response.

In case you have the drivers not installed (the "android" device without drivers in device manager), try with "google adb driver" ->
or pdanet
however the lg one should be fine (if not -> try one of the ones I mentioned)

I used PdaNet to install the LG drivers, and inputting the command "fastboot devices" now shows
Code:
? fastboot
Inputting "adb devices" does not show anything, however.
I then attempted to flash a recovery, TWRP version 2.8.7.0 with the command "fastboot flash recovery "recovery.img"". However, the phone's screen showed the following:
Code:
[998960] Error: Command never completed
[998960] Error: Auto CMD12 Error
[998960] Error: Command never completed with errors
[998960] Failed Writing block @ 1
How do I fix the partitions and find the files "aboot.img" and "laf.img"?
Thanks for your help so far, I'm glad that there is progress now.

it has to be fastboot flash recovery recovery.img (where recovery.img is twrp.img, twrp.bin, recovery.img or similiar, without any quotations)
What happens when you try to enter TWRP? Are you doing it right? Hold volume down and power ---- wait for lg logo an release for less than a second and keep holding again.
aboot and laf are downloadable or extractable (from KDZ/TOT) -> use bullghosts kdz/tot extractor

I retried the command fastboot flash recovery recovery.img but it resulted in the same output as before.
I followed the exact instructions to enter TWRP but it just stays at the LG logo screen. I've held Power+Vol.Down for about a minute after quickly releasing it+pressing it again at the LG logo, but it just doesn't do anything.
I've found myself a Lollipop KDZ file. The CyanogenMod I was running, however, ran on Android 6.0 Marshmallow. Will I need a Marshmallow KDZ file instead?

Solution
I've found a solution to my issue, at least.
Downloading "recovery.img" from here, putting it in the same folder as fastboot, and then using the command
Code:
fastboot boot recovery.img
booted my phone properly, into cm-13.0-20160322-NIGHTLY-d855 (CM13 March 22nd).
However this resulted in all data being erased, including internal storage.
After using Flashify to re-flash TWRP (just in case), everything works as it should.

Regarding teamviewer - it was an exploration mission so I would see how your device behaves, maybe wrong drivers, maybe..100reasons (I certainly would write it in here if there was a better idea on my side)

No problem, sometimes you have to trust people
There were people who asked for help, installed teamviewer and didn´t gave any control permissions (which is fine). But they were expecting someone is having soo much free time to explain things (which I would if I had time)

The rest of my phone was unusable (no working recovery, no download mode, just the LG logo or this fastboot mode)
I tried several TWRP recovery versions & flavors, but so far, I only successfully reboot in recovery using CyanogenMod recovery file (download.cyanogenmod.org/?device=d855). Though I was not able to do much afterwards apart some adb commands that were not working either.
Code:
dd if=/dev/zero of=/dev/block/mmcblk0p20
dd: /dev/block/mmcblk0p20: write error: I/O error
This recovery img did the trick and I'm now back with a CyanogenMod ROM and a wiped phone.

H815: No recovery mode (bootloader unlocked, TWRP 3.0.1 installed)

Hey guys,
I'm trying to root my G4 loaded with MM 6.0. I cannot get into Recovery Mode no matter what I do.
I have tried the key combo (power+down, etc) - it does nothing. If I use adb reboot recovery, I just get the dead Android guy with the exclamation in red triangle. (which is perhaps a hint as to why the key combo doesn't work.)
I followed steps to unlock the phone's bootloader via LG's dev site (success) and I've installed TWRP 3.0.2-0-H815.img but I can't get into Recovery mode. **The phone continues to work fine** and I can get it into Download Mode.
After having no success with TWRP, I thought, f*ck it, since I've gone this far, let's go with CyanogenMod instead of stock, so I installed cm-13.0-20160415-NIGHTLY-h815-recovery.img
I was also able to use adb to push CM 13 (nightly build 20160415) and Gapps (arm64 6.0 20160416) successfully to phone, but it's obviously no use since I can't get to Recovery Mode.
I'm wondering if someone can please suggest a solution or at least a next step.
When I use fastboot flash recovery twrp-3.0.2-0-h815.img it takes 0.718s 'send recovery' and 0.282s 'writing recovery'.
[solved - probably Win10's no-ask driver update policy] New problem: After going back to TWRP, fastboot devices shows nothing and my device is showing up in Device Manager as LGE Mobile USB Composite Device, whereas I specifically changed it from the LG drivers I installed to Android ADB drivers. The device doesn't even list the Android ADB driver as an available option now. WTAF?!? Maybe this is more Win10 driver-auto-update malarkey?
OS = Win10x64
Kernal = 3.10.84
Build number = MRA58K
Software version = V20d-EUR-XX
Developer options are available
USB debug is enabled
OEM unlock is enabled
I'm using the stock USB cable
Additional question - tutorials say to back up NVRAM and IMEI before doing anything risky, but I can't get those without root. How does this make sense?
EDIT: NOTE: You should be using the arm64 version of Gapps on LG G4 H815.
Thank you very much to everyone who stops in to take a look at my questions.
All the best,
Dax.

Hi
I had the same problem with Win 10 not seeing my H815 properly (same device name in Device Mgr as yours) I reverted to the older Lge drivers, 4.0.3 if I remember correctly and the phone showed up properly and I was able to use LG UP to update/downgrade etc.
Like you I have since tried to install TWRP but I cannot new get root with Kingroot 480 although it worked previously on V81520D it does not now.

try fastboot boot recovery twrp-3.0.2-0-h815.img
then tap IMG instead of ZIP (bottom) -> install img and flash the twrp img

Hi Stransky, I reinstalled the adb-setup-1.4.2.exe package which also contains drivers and now ADB will see the phone (which is good), but Fastboot still says waiting for devices (bad). Thanks!
I also changed the default driver from 'LGE Mobile ADB Interface' to 'Android ADB Interface' (as per tutorial instructions).
Hi Bender_007, thanks so much for the tip, I'll try it as soon as I can get Fastboot working again. Cheers!

Okay, so I learned ADB is for Android or Recovery mode, Fastboot is for 'HBOOT' (bootloader) mode.
As expected:
adb devices returns "List of attached devices: LGH81579d3bc56 device".
If I use the command adb reboot-bootloader, phone restarts in bootloader mode.
Then adb devices does nothing, but fastboot devices returns "79d3bc56 fastboot".
When device is in bootloader mode, it shows up in Windows Device Manager as 'Marshall London Bootloader Device'.
Bender_007, the command "fastboot boot recovery twrp-3.0.2-0-h815.img" doesn't work. It's invalid syntax. "fastboot flash recovery twrp-3.0.2-0-h815.img" works as per original post.
Any other suggestions?

Hm, put the twrp inside the same folder where your fastboot and adb are. Then start command prompt in the very same folder and type fastboot boot twrp... And that should be it. That means if everything is normal and the system is bootable.
Pardon, fastboot boot twrp(whatever the name is)
Not: fastboot boot recovery twrp..

I am stuck probably on the same issue with win10. It seams like I was able to flash twrp recovery but I can't enter it. Already factory reseted it 3 times while trying to enter into custom recovery.
Any advices what to do?

The best solution there is:
1. put adb, fastboot into a directory (let´s say c:\adb), put the twrp-3......img into the same folder
2. adb reboot bootloader
3. open command prompt, cd c:\adb
4. fastboot boot twrp-3.....img (where twrp-3....img is the actual name of the twrp img)
it will boot to twrp, now you can either copy the twrp img to the phone and flash it(it will ask where to flash - tap on recovery--don´t tap on boot)
You might have to tap on zip/img toggle to enable img flashing first
should you need more help just post in here

Yep that did the trick. thank you! I was able to load recovery with the fastboot boot twrp.. but didnt realize that i can install it by the loaded twrp lol. Now I can finally confirm 2x YES and it gets me into TWRP. thanks again!

Can I make one little tip for everyone else? Follow this guide to the end: http://www.technobuzz.net/unlock-lg-g4-bootloader/
Step 1 is the easiest way to install adb, fastboot and drivers in one go.

Same problem here:
Software version = V20d-EUR-XX, Developer options are available, USB debug is enabled, OEM unlock is enabled
I can boot into recovery via bootloader: fastboot boot twrp-3.0.2-0-h815.img but:
1. had I to allow to modify system partition modifications?
2. how can I boot in recovery from system? with adb I always get the red-triangle Android on its back und with hardwarekeys after shut down the devise, I#m coming to stock recovery: factory restet no/yes

1. Yes
2. While you are in twrp just flash the twrp IMG again via twrp itself. It has the option to flash img instead of zip.

When i boot into recovery at the moment, the "modify-dialog" is away...
But I will see after "re-"install the twrp how it works...

Did it, worked!!!
on system: "adb reboot recovery" leads to twrp!
there are no hardware-key-solutions to get to recovery...
with the hardware-keys (after shutdown -> power + vol down -> release power for a second when LG-logo pops up) I get to the factory reset no/yes dialog...

On the factory reset choose yes twice. Normal for lg

Hey, i was in twrp and i wiped data and system, and it suddenly reboots...
after booting it shows some error messages then it reboots again in loop... i have no OS installed currently

Don't do this if you don't want to have your phone baseband completely removed meaning no sim card function at all. I did exactly this when trying to install stock room and it deleted my baseband. Luckily I had made a backup a month before that. I restored it from the backup and the phone (sim card) started working again.
Anyways, back to the original issue. So you're saying your phone isn't recognized in fastboot? When I wipe system and data and then go into fastboot and enter "fastboot devices" it shows nothing but I can still flash files into the phone. I'm guessing this is because the phone has no 'name' due to the system wiping. So try going into fastboot on your phone, connect it to PC and open adb, and then enter the command 'fastboot flash recovery twrp.img' (download the latest version of TWRP for Lenovo P2 and rename it to twrp).
If then you are able to enter TWRP after rebooting, download stock Lenovo P2 ROM and flash it.

Recovering data on a DEAD Redmi Note 8 PRO

Hello,
I hope this is the right section for this post.
I've been using a Note 8 Pro with zero issues until one week ago when I accidentally dropped the phone in the water.
After a few seconds submerged the display turned off and I felt an intense heat coming from the zone of the battery.
Having no chance to recover the phone (tried with Isopropyl Alcohol too) I decided to open it and manually dry/clean each component, having seen the situation inside gave me the phone is dead but I still want to recover some pictures/data from it.
Before opening the open Minitool was not detecting any device on my Windows Laptop, after cleaning each component Minitool is instead detecting the phone via USB, but I still can't extract any data because the "Usb debugging" option is not tuned on (and no the device is not rooted).
Is there any option to extract data from the phone? There's a way to turn on USB Debugging via ADB on a non-rooted phone?
Thanks,
Andrea.

how about trying your luck with a service ? most of the time they do have access to special programs, which have a better functionality than adb.

Thanks for the hint, but I am not happy with the idea of someone playing with my data

1. Try reboot phone to recovery
2. Connect it to your computer (download Platform-tools)
3. In the folder with Platform-tools open cmd
4. In cmd - adb shell
5. cd storage/emulated/0
6. ls
7. Now, using the commands, drag files from your phone to your PC

Thanks for your hint.
No luck so far, I think because the phone is not in recovery mode.
I can hear the phone starting up several times (hear the jingle) so I think it's in a reboot loop and I don't know how to boot it into recovery mode wo a working display (tried with power/volume up combination with no luck).
From the windows taskbar I can see that the phone is recognized for a few seconds before it restarts.
EDIT: trying to switch the phone on with the combination "power/volume down" brings to a kind of stable state and I can now see the phone in the windows taskbar recognized as a generic "android device". Still no luck when trying to access the phone as there's no device in windows and no device obtained through "adb devices" command.
EDIT1: I think that the phone is in "FASTBOOT" mode. If I type "fastboot devices" I can see it detected but still can't access it.

Any idea? Should I give up?

If it's popping up and down you need something to keep track.
You can try my UsbLog.exe (in the sig), it just sits there and shows what devices appear (if they have a driver) and disappear.
Try these to see if anything is working:
Code:
C:\>fastboot devices
C:\>fastboot getvar all
C:\>fastboot oem device-info

Yes it's popping up and down when it's booted in recovery mode whilst is stably connected when in fastboot mode but in this case I can't access the internal memory of the device.
I didn't get the purpose of logging the devices connecting to the USB as I can see the device connected for a while and correctly recognized as Redmi Note 8 pro but as it keeps popping out windows have no time to show it's folder.
As for the code you wrote: i will try asap but already tried with "fastboot devices" and I get the phone correctly listed but still can't access its memory as told.

After rebooting the phone in fastboot mode I can see it recognized as a generic android device from windows (still can't access the storage folder of the device).
fastboot devices----> I get the device listed with a series of numbers/letters
fastboot getvar all---> I get a list of information on token/token version/partition type and size/baseband/bootloader etc.
fastboot oem device-info----> FAILED (remote: unknown command)
So I think it's clear that the device is in Fastboot mode and instead is in a boot loop when started in revocery mode.
Is there a way to extract data from fastboot mode?
Thanks,
Andrea.

If you put a custom recovery on it in the first place you can try reflashing recovery from fastboot.
Fastboot doesn't allow you to read anything.
oem device-info is obviously an oem command that might not be on any device.
You've got a Mediatek processor. That has some low level equivalent to Qualcomm EDL, but I have no experience with that.
If you can get there you can download the user data partition, but it's probably encrypted. Also no experience with that.
The easiest is if you can get the system to mount/decrypt the partition.
You've tried the normal system too?
Is this A/B? Have you tried changing slots?
How much time does it stay up in recovery? Do you have ADB? Maybe try:
Code:
# stop recovery
Does that prevent it from looping?

So I should try to flash a custom recovery like TWRP for example?
What you mean with "normal system too"?
Changing slots you mean changing usb port?
It stays in recovery less than one second so I can't give any command via ADB.
EDIT: cant' flash any custom recovery because the bootloader is locked.
If I Try to unlock the bootloader via MiUnlock I get a warning saying that all data will be erased.
Any idea on how to unlock the bootloader wo wiping all the data?

My bootloader is unlocked!
Thank you very much.
Now I am going to try to flash a custom recovery mode via fastboot in order to access the internal memory of the phone.
EDIT: I've just flashed twrp-3.6.2_9-0-begonia.img but still can't boot into recovery mode.
Any hint on how to extract data from the system now?

You really want to boot the normal system because that's the best way to get decrypted data.
I realized that you don't have ADB enabled there.
You should look at B. Kerler's https://github.com/bkerler/mtkclient/
If you can pull the boot image off your device then I might be able to fix it so that you have ADB.
You'd have to flash it back in fastboot or mtkclient.
You can also pull a copy of userdata off the device with mtkclient.
As far as booting into recovery, there's a way.
Here's how, if you don't have A/B (that is you flashed TWRP into recovery and not recovery_a or recovery_b)
then you can fastboot flash a special file into the misc partition and it wil boot into recovery next reboot.
To return things to normal you have to flash the empty file to the misc partition.
Code:
C:\>fastboot flash misc misc-rec.img
C:\>fastboot reboot
Only do this if you don't have partitions that end in _a or _b

I really don't know if I have partitions A and B as you mentioned and I think there's no way to check actually.
I confirm I don't have "USB Debugging" active on the phone.
So if I understand correctly I should do the following:
- Flash misc-reg.img via Fastboot
- Boot into recovery just rebooting the system after flashing the above file;
- use MTKclient to dump userdata or boot image to enable ADB on (I will need help with mtkclient I suppose).
Is it correct?
EDIT: flashed TWRP first and misc-rec then rebooted via Fastboot/Reboot but nothing happens.

TWRP cant boot because you used wrong one. Search again in that unlock bootloader channel and use suitable one.

Hmmm, I am almost sure that the TWRP I've flashed was listed under Redmi Note 8 pro page. Can you please indicate more precisely where should I sera
EDIT: I think I've downloaded and flashed the correct TWRP file.
@Renate can you please detail your method so I can try to extract data from the phone?

1/Yeah it's official. You "flashed correct TWRP." Downgrade to Miui Android 9 (_9 in it's name) to boot into that TWRP and lose your data.
2/In unlock bootloader video above, search other video in his channel playlist and find TWRP video suitable for your Miui version.

Can't find the right video, can you kindly send me a link (I am on the latest Miui version and I am in Europe)?
In all the videos I've seen on his page he is using the device to install TWRP etc.
I think I just need the correct TWRP version for my MIUI release and then I'll flash TWRP and misc-reg.img. Is it right?

Use brp 3.5.2 v3.1 or V3.6 to decrypt Miui 12.5
