[GUIDE] How To Enter Fastboot Mode - G4 General

This is the method tried on H815T model. But I think this should work with also other H815 models (other devices cannot say). Thanks to @autoprime, @thecubed and @Unjustified Dev for this.
Disclaimer: I am not responsible if your device gets into any more trouble for this.
Steps:
1. Download & clean install LG Drivers in your pc if u don't have it already.
2. Go into download mode by presing down the UP button and connecting the usb cable to the pc.
3. Go into LG ROOT folder. see this link to download: http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
4. Double click on ports.bat to know your COM port. Let's say it's COM4.
5. Open a windows command promt by Shift+Rt Click into the Lg Root folder.
6. Now send these commands:
Code:
Send_Command.exe \\.\COM4
It will reply
Code:
SPECIAL COMMAND : ENTER , LEAVE
#
7. Now command type
Code:
id
It should reply
Code:
uid=(0)root gid=(0)root
#
8. Now type
Code:
dd if=/dev/zero bs=8192 seek=35840 count=5120 of=/dev/block/mmcblk0
It will reply
Code:
#
9. Now pull out your battery, put it back in, go into HARD RESET mode by pressing down DOWN BUTTON+POWER BUTTON together and when the LG logo apprears, release the power button for a second and press it back again.
10. Now in HARD RESET, it will ask you whether you want to reset everything or not. Select "No" and it will take you to fastboot mode.
Special note:
1. @autoprime told me to factory reset everything before starting this whole process. I did as my bootloader was locked. Don't know how it affects in unlocked bootloader.
2. How to get out of fastboot normally: I don't know it quitely. My bootloader was locked, so neither I could flash any system file through fastboot, nor "fastboot reboot" or "fastboot reboot bootloader" worked for me. @autoprime told me to get out of fastboot, manually go into download mode, then pull out your battery and put back in. Actually you can't get out of the fastboot that way until you flash a KDZ.
Thank u. Reply in the comments if fastboot could help you any.

Hi,
Thank you very much for this Guide. Unfortunately, having tried to unbrick my device (H815) previously by hard resetting and not having access to Android to re-activate ADB, the Shell (Send_command.exe) didn't help me (at every command it returns a "FAIL" message, my phone is recognized by Windows by the way).
So I couldn't get into Fastboot by following this Guide.
Hope it works for others, waiting for results!

You couldn't get into fastboot or u couldn't flash anything in fastboot? I cannot make my device recognised in adb too, but it is recognised in fastboot. U need to have the adb and fastboot setup in your pc. But I couldn't flash anything in fastboot as it shows my device is locked although someone said, theoritically it was supposed to flash system files through fastboot.

I couldn't get into Fastboot at all. Any command typed in send_command.exe gives "Fail" as result... Phone is connected in Download Mode and recognized in Windows, DIAG1 port is COM4.

True. I didn't realise that before, so gave it a try. But this may help those with unlocked bootloader.

This does not work for me, I have an unlocked bootloader, but just get the response "FAIL".

And... Why don't you just zero the laf partition instead through an adb shell? What does this do that's different?

If we can get into fastboot, can we then do something like
Code:
fastboot boot recovery.img
to get into a custom type recovery and do a backup? I'm on the AT&T H810 version, locked bootloader, I don't know if that means a big fat NO lol or if this method of getting into fastboot mode would even work on my variant.

no one should be wiping laf or recovery to get into fastboot. it's a dumbed down fastboot that doesn't let anything flash or boot. the directions I gave OP were in a PM as a last resort because he was stuck in download mode with no booting and wanted to try fastboot. It was never meant to be suggested in public to users who might think they can get anywhere with it.

Holly molly sir! You are a legend. Long story not so short. My lg got the bootloop bug. Took 2 months to fix, but apparently they changed my locked to three uk H815 "eu open" motherboard with actually unlocked one. So I was finally able to unlock boot-loader, root and **** up (LOL). Apparently I didn't install twrp properly (you'd think "fastboot boot twrp.img" would not install it but run it once) And i was following this to get Android M on. But it requires reboot before boot-loader is flashed. Right when i clicked reboot i figured it wont start in twrp but in stock recovery. So I couldn't even get proper bootloop, it would cut half way into the LG logo. I reckon kdz-ing would havedone the trick, but god it takes ages to DL the kdz file. So in the mean time i found this legendary post. The odd thing was i had to click Yes, on the factory reset screen, but it got me to "Fastboot mode started" and from there i booted into twrp and finished what it had started, currently its Optimising app 35 of 55. Nice one OP, Nice One!

Fastboot

How do you guys boot to fastboot if you have turned your phone off? I mean the actual fastboot ("black Huawei logo") not the recovery and not the pink bootloader. I can get to it if I reboot my phone if I press reboot and then bootloader, but is it possible without it?
Seems like there is no other way. Right now I can start it in fastboot mode with "adb reboot bootloader" and the custom ROM I have on right now. If anyone wants details, post here.
-e-
Weird discovery I made. While trying to flashall it says the device is "swordfish"... If I flash system.img separately it says "no partition table exists". Anyone has used fastboot before?
Nice. With the new Android version, the product shows MSM7630_SURF. It now properly boots to fastboot without going to charging too, so thats an update.

Thanks! I was trying to set up my UDEV (51-android.rules) and your post helped me boot into the bootloader mode to get the right idVendor & idProduct codes.

I tried fastboot, but I just get a black screen with huawei logo. No any function, no adb connection, no menu entries or anything and no buttons work. And I can exit only by remove battery. Is this right?

There's an external tool called fastboot which handles that. There you can reboot or even continue the boot.
Fastboot is broken as far as I know, no partition table exists.
Sent from my U8800
You mean the fastboot from adb tools which can used from command line? This cannot work because there isn' t adb connection on bootloader mode.
Or is another tool which can be flashed or something to device?

I think you are confusing pink screen with fastboot/bootloader. The fastboot is the node where it stays in the Huawei logo.
Sent from my U8800
No, I know the difference. I get this screen, but nothing else. On my previous device, fastboot has some functions included flash rom, reboot and some else that I don't remember. I also could from adb to use fastboot command.
On X5 I just get this screen.
Maybe they disabled that in B522 too, I am not sure. It was bugged anyway. I only tested it on B138 and B518.
Yes, I have 522 and I thought this too. I've tried on B138 1-2 times and was the same huawei logo screen only too. I didn' t tested it more because I thought that just this mode is disabled and used pink mode only. In B138 sould appear something else on screen, or only commands from adb work?

I softbricked my LS980 and cannot escape fastboot. Assistance Requested.

Had a problem with audio playback (volume always high no matter what). Decide to flash. PAC for my Sprint LS980. I see this:
Seems to be a lot of confusion so I'll clear things up..
ZV7->ZV8->ZVA is how the ota history goes, with ZVB on the way.
If you're on stock ZVA, your aboot (bootloader) may not be downgraded, in that case, use FreeGee from Play Store to install a recovery, it will automatically downgrade your aboot.
if you have the ZVA Radio, just flash furnace or dr87's kernel after you flash an AOSP ROM, all done.

Sorce: http://forum.xda-developers.com/showthread.php?t=2669074
Seeing the last sentance, I think that if I flash ZVA Radio, SlimKat ROM (the one that causes me problems) and then dr87's kernel I could try a ZVA experience. I flashed SlimKat again becuase I was going to change anyway, I wanted to try it with ZVA.
Tell myself why not, I do it.
Fails but I didnt pay much attention. I reboot.
Stuck in fastboot mode and cant escape. Recovery is a no-go.
Tried flashing both ZV7aboot.img and twrp2.6.3.0.img into their appropriate partitions (boot and recovery).
Still having problems, but now I cant do any button combination (except DownloadMode. Cant turn off) after ZV7aboot.img flash.
I dont want to erase my memory (~26GB of valuable data). Is there a way to flash a ZV8Radio.zip from fastboot? I think thats my problem, but Im not too sure. Just access to recovery would allow my to fix my problems.
Thanks anyone for any help! I think I really screwed myself over this time. Thanks everyone!
Edit: Anyone know where to get a boot.img and system.img for the Sprint LS980?
zv7_aboot.img isn't a boot.img, it's the bootloader. Use FreeGee to install twrp, it will handle the aboot for you. Then you can take advantage of the last sentence.

I am stuck in fastboot. No recovery. Download mode is also accessable.
Which of the following would help:
* System.img and Boot.img (where to find em?)
* A kernel .img (Do they exist?)
* Flashing the ZV7 or 8 aboot.img oncemore with twrp.img again?
Thanks for coming to help! It means a lot.

If you can boot into a rom, use FreeGee to install twrp. If you can't boot into rom and recovery, you need to flashtool.

Flashtools is asking for login and password. ?
Does this mean I have to wipe all user data in order to use it?
Edit: Do you know where System.img and Boot.img could be downloaded? I think its my only hope.

Thanks for the link! That was extremely helpful.
What I did to gain access to twrp again was:
Download boot.img from the link.
Download aboot.img from link.
Download twrp.img (but this isnt necessary, file is already available on phone. No need.)
* Enter command 'fastboot flash boot boot.img'
* (If you hold power it starts showing LG Logo.)
* Go back to Fastboot. Enter command 'fastboot flash aboot aboot.img'
* Now TWRP access is regained! Phone doesnt boot normally, must flash ROM and stuff again.
Thanks a lot! This was an okay first fastboot experience.
Soft Bricked Sprint LS980?
Hello, I'm having a similar problem. I haven't had a phone for a couple years since tinkering with my Evo and thought I still knew what I was doing with my new G2. That proved to be incorrect.
I had it semi rooted. (I followed the instructions using Ioroot and Kingo) I wasn't able to change APN and use GSM for Metro PCS
After reading up about the spark patch I followed a tutorial (not very well obviously) and managed to get the phone will it will no longer boot.
I can get it into bootloader, and a frozen in download mode. otherwise it just hangs at the LG logo.
Is there a way to recover from bootloader?
I copied twrp-2.6.3.2-g2spr.img and zv7-aboot.img to the phone and did the following.
Here are the commands I used with the guide. I looks like I was using 2 different guides at once..... :/

Also, dont blame me if your phone dies, all this stuff will void your warranty of your phone and your toaster!
Hit the build number under about phone --> software until developer mode is enabled
goto developer mode turn on mtp mode
go download twrp from there site http://www.teamw.in/project/twrp2/197
I used kingo but cant link on xda ,, google it .. its on cnet as well
get http://koush.com/post/universal-adb-driver install (works on all windows)
get http://www.xda-developers.com/androi...oot-installer/has good quick adb install it
copy the downloaded openrecovery for sprint onto the phone directly into the "root" folder (root folder being like when you look at yoru C: drive in windows explorer that is the root folder under linux), when you plug into the pc, make sure in mtp mode
with phone still plugged in run kingo and root it
it will reboot
with phone plugged in run "adb usb" from command prompt on pc (from the link for adb that it installed, it will open a command prompt for you in the proper folder when you click it)
approve adb connection on phone
then run "adb shell" from command prompt on pc
type su, approve it on phone
paste this next line exactly at the prompt
********** this is the line I used from a different guide ***** dd if=/sdcard/zv7-aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot

let it flash
it will say bytes copied and you will be good
type reboot inside the shell
the phone will reboot
I use goo manager from play store to boot into recovery, I dont even know the key combo for it yet.
Any help would be appreciated, thank you.

Alright, sorry to comment on something 3 months old, but I just had this problem and managed to solve it.
When in the mode described above, you are still able to use Fastboot. Get a linux computer and install fastboot.
Then, go here: http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zvc_partitions
Download the images for laf, aboot, boot, and recovery.
type the following commands in fastboot:
fastboot erase boot
fastboot erase aboot
fastboot erase recovery
fastboot erase laf
fastboot flash boot 6-boot.img
fastboot flash aboot 4-aboot.img
fastboot flash recovery 10-recovery.img
fastboot flash laf 11-laf.img
fastboot reboot
This fixed the problem for me. Good luck!

Sorry for not replying, but I see you managed to fix your problem. All you needed to do was download .img files, then enter commands through fastboot. Although it is slightly more complicated than that, its the rough outline of what needs to be done to fix it. Nice work fixing your problem. I came back to this thread to remind myself of the commands that need to be entered (My comments help myself).
I think I am just going to copy-paste the quoted box above if anyone needs instructions how to do this. Thanks for the quick guide I can use to help others!

foolishly he then used fastboot reboot BEFORE reflashing the necessary images
this leaves me with a device that is practically 100% empty all hardware no software

and i can communicate with the device on ubuntu terminal although im not too farmiliar with terminal syntax so im not having much luck
im convinced it is as simple as reflashing at least a working recovery or download mode from which i can install everything else i nee

between QPST, Terminal, and or some other method
sorry for Noob ish ness

Sorry, I barely understood what to do originally. What you have to do next is to reflash the aboot/boot/ whatever partitions but getting to that position might be difficult. Maybe some sort of command would allow you to connect to it oncemore?
Sorry, try to look into it more and see if a dev could help. Try posting something in /r/lgg2 but then again I cant be certain anything would happen. Good luck!
Easy guide
Since the problem keeps happening to people heres a quick tutorial I made.
Download and install this (PC only?)
Now go here. (D802) (D800) (LS980) (VS980) (D803) (Device tree/others)Download the images for laf, aboot, boot, and recovery.
Place the 4 .img files in the same folder. Control right click in that folded and open terminal. If this isn't how you open terminal in a folder search"how to open terminal in a folder".
(NOTE: Commands below will differ from the file names. Change the values in the parenthesis to match the files, HOWEVER, do not type the parenthesis into the terminal prompt! It will not work if you do.)
type the following commands in fastboot:
fastboot erase boot
fastboot erase aboot
fastboot erase recovery
fastboot erase laf
fastboot flash boot (6-boot.img)
fastboot flash aboot (4-aboot.img)
fastboot flash recovery (10-recovery.img)
fastboot flash laf (11-laf.img)
fastboot reboot
You should be fine now!
Unbrick Ls980 formatting partitions
Do this: (only for LS980)

i tried this with almost all model files but still on fastboot any other option?>
I want to say thank you so much for this thread. Just got a new (refurb) G2 switching carriers to T-Mo and my idiot self used the wrong root program and soft bricked to fastboot. 4 .img files later and a few commands and I don't think I've ever been so happy to see a download screen on a phone...

Locked Boot loader, Encrypted Device, BootLoop, No Recovery/ Factor. HELP

So the title pretty much says it all..
I have a Nexus 6P
Last night It got stuck in a bootloop. The only access I have to the device is it will launch into the boot loader. But no options work, factory, recovery do not work. USB Debugging was turned off, OEM unlock is turned off, developer options are on. But I have zero access to the android only the boot loader screen. Fastboot does work but it gives me "DEVICE IS LOCKED" on most commands. Oh and the icing on top is I'm on Android N 7.0 beta.
I've ordered a replacement, but I have all my personal data on the phone. I'd like to either fix it and get it working so I can get all my stuff off it. Or at very least try to wipe the device.
Also Fastboot Format, erase, do not work. It says Locked Device. HELP PLEASE. I can answer any more questions.
can you adb pull and push files?
If so, on your Windows machine, type this:
Code:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
It won't connect via ADB only Fastboot.
adb devices

Not sure if this will work, but try downloading the latest TWRP img file from their website, then running this command:
Code:
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
If you get it into recovery, then pull the files you need for a backup, and then use adb push to push a new ROM to the device.
Make sure you format all partitions/data.
Note: adb push should work better in recovery, vs. the command line that didn't work earlier.
What do you mean by "recovery doesn't work"? Please explain what happens when you boot into it.

Why not download stock Marshmallow and attempt to flash?
https://developers.google.com/android/nexus/images#angler
A locked bootloader should still allow you to flash a signed ROM.
An unlocked bootloader means you can boot and install anything.
Rule #1 If you are running *ANYTHING* other than an OTA, unlock the bootloader!
Unlocking the bootloader DOES NOT void the warranty.
Final note, it's encrypted. If you can't get into it, nobody interested in your data can.
Even if they can, it's block level encrypted. Who cares, no need to wipe.

When I click down and then power on recovery it should go into the recovery. But instead it just gets back into an endless loop of starting.

On a side note. I am running stock android N 7.0 and it was OTA. I just didn't think to unlock it since it was all done OTA.
Thats what I'm thinking too on the data.

That means you need to unlock your bootloader, which should already be done, or if it's not, it will erase your internal storage.
You can unlock your bootloader, or try too, with
Code:
fastboot flashing unlock

He said OEM unlock is turned off so that won't work.
So any luck to boot this sucker ? Don't even have stock recovery ..
have you tried "fastboot boot boot.img" from the correct factory image ?
Boot loop plus no recovery equals BLOD. Sorry but likely you are done.

Stuck in Bootloop

US996 Unlocked, stock rom. I was in XDA Forums and saw there were app updates, one being Play Store. I updated. When I tried to get into Play Store, the message "this version of play store is incompatible with your device, go to settings and disable app update (or something like that). I tried but the app was not listed in settings. I tried to reboot and now the phone bootloops. All I can get is the warning that the software cannot be checked for corruption and then a quick display of the LG logo, then screen off, and then LG logo again and then warning screen, etc. If I try to reboot into recovery I get the Factory data reset screens and I answer both "yes" and the phone goes into adb mode.. From adb mode I can fastboot reboot, which puts me back into the above loop, or fastboot bootloader, which merely returns me to the adb screen. What can I do now?
Maybe try relocking the bootloader. I am pretty sure (someone correct me if I am wrong) that that pop-up of the "cannot check for corruption" usually only shows when the bootloader is unlocked.

Try entering

into Fastboot on your computer to see if it says it is unlocked when in fastboot mode.

I get "FAILED (remote: unknown command)"
Do you have fastboot installed on your computer? (Something you would have had to have intentionally installed) If not google Minimal Fastboot /ADB and install it, enter the supposed ADB screen you are talking about and see if it makes contact with your phone.

I have the fastboot on the PC that I used to unlock the bootloader.. I enter fastboot on the PC via the administrative command prompt. With the phone in the fastboot mode, I type "fastboot devices" on the PC and get a proper response (LGUS996ab**** fastboot). If I enter ""fastboot reboot" I get the bootloop. If I enter "fastboot bootloader" I wind up in Fastboot Mode on the phone again. I was hoping there was a "fastboot recovery" command but there doesn't seem to be. I don't know what to do next. I am not all that familiar with what can be done from fastboot. My only experience with it was when I unlocked the phone. I am desperate!
Okay, so if you do not have TWRP installed on your phone, then I don't know if you can save your data. You can try to
Code:
fastboot erase cache
and see if it helps, or if not and just reset the device fastboot oem lock I think. Maybe ask around in the unlocking help threads or perhaps someone with more knowledge will chime in. If none of this works, then there are some instructions on how to get your phone back to stock in the News and Guides section.
EDIT: Maybe try the power+volume down. It may work? I have tried it and never got it to successfully work. But you can try it.

Thanks for your help. I DO have TWRP installed and have used it often for backups. But now the only way I know to TRY to get to it is by the power/vol down until LG logo, then release/repress power button sequence but this just gets me into fastboot mode. II have some recent backups saved on my micro SD card - is there any way to flash one of them through fastboot if I load one onto the PC?
Yeah. My bad. Okay, so how I get into TWRP is through the EasyRecowvery.
Go ahead and download it from Git-Hub (1.3b3).
Now extract it and run the cmd program. Enter 5. which is extras and stuff and then enter 5 again in the sub menu which will let you boot into recovery. When you are in recovery, and plugged into your computer, you should be able to either flash or drag and drop like a flash drive on the the phone. Hope that helps a little bit.

I don't have T-Mobile. I have Verizon Wireless on the US996. Will that work?

Since you are only rebooting into recovery and not flashing anything it might. If not, it will just fail and not harm anything. Last thing to try is the
Code:
adb reboot recovery
which is the only thing I can think of and I think you already tried it. Otherwise you will need to just go stock.

[Solved] Huawei P9 Lite Bricked

Hello, I was curious if anyone could help me with unbricking my phone, my phone has no custom recovery installed, the bootloader is apparently unlocked (OEM unlocking is disabled), FRP lock is enabled, I cannot flash anything (Command not allowed), relock bootloader (Root type is at risk), Unlock bootloader (Command not allowed), any help would be appreciated.
Edit: I also cannot boot a from a recovery img locally using fastboot (Command not allowed)
EDIT: Fixed it using DC Pheonix and flashing VNS-L22C636B140 OEMINFO and flashing B160
Hi, try my way. https://forum.xda-developers.com/showpost.php?p=77307223&postcount=30 Just pick CxxxBxxx that suits your model. Try to unlock bootloader again via SRKTool, I think FRP must be unlocked too...

Are you sure you run from inside the folder where adb.exe and fastboot.exe is? Boot to bootloader and use terminal pointed to fastboot.exe. Shift+right click -> open command line here. Make sure your devices is listed: adb devices. If device is shown: adb reboot bootloader, to reboot to bootloader. If not, install adb drivers / huawei drivers.

Yes I am sure, also, I have no way to access ADB since there is no recovery on the phone.
Only thing I can do is boot to that eRecovery screen with the option to download, reboot or shutdown. (Automatticly goes to here), or boot to bootloader

Well if you can access to bootloader then you able to use fastboot commands. ADB is not related to recovery anyhow, you use windows command prompt to use adb and fastboot. IF FRP is locked, unlock bootloader again. I quiet don't understand how the command are not allowed or so. You are definitely doing something wrong.

The problem is I cannot unlock bootloader again, flash anything or boot into any image in fastboot mode, I always get "ERROR: (Command not allowed)", attempting to relock the bootloader shows "ERROR: (Root type is at risk)"
EDIT: I have done some research for the dload method, If I want to dload to hopefully fix it, I'll need VNS-L22C636B381, but the official link from the hicloud is dead, if anyone could help me with that, that'd be great.
Last EDIT: Ended up scratching the above idea as it didn't work, gritted my teeth as I bought DC Phoenix and will update if it works out with the .APP from the latest package I found on firmware finder.
