Cannot boot into bootloader/fastboot

Hello guys I have H815 and I can't proceed with unlocking bootloader cause my phone cannot boot into bootloader/fastboot mode. I'm not newbie, but with this phone everything goes ****ing different than in instruction.
I the instruction there is adb reboot bootloader. Of course my phone is seen in adb mode but after this command it just reboot to system. I tried also key combinations with no luck...
What to do?
My system is android 6

Hi,
I'm the same...
looking for solution I found this on Youtube:
Pratically, you have to press vol up while connect USB on PC....
I haven't the G4 with my today and so I cannot test if this is a valid mode...
If you do this, let me know if you can enter in fastboot mode

I did that and yeah it entered this mode but it's not valid bootloader/fastboot mode. It's some service mode to update firmware. Anyway it's not visible in pc as a normal fastboot and I cannot proceed further with unlocking bootloader...
Edit: it's download mode... So as I said it's not fastboot mode.
Anyone can help?

Seriously nobody? I thought this phone has good community and support...

I'm facing the exact same problem with my H810 on 6.0. Sick of not being able to root atleast.
Seriously hasn't anyone on earth found a way to boot this **** in fastboot? I mean there are a number of tutorials but everything goes different as F*** with this thing. Hope someone will update with good news. :fingers-crossed::fingers-crossed:

You can check out UsU. That is an unofficial bootloader unlock

Thanks yeah I checked but that's for ARB<=2 devices. I forgot to mention earlier this godforsaken thing is ARB3.

I have an H811 (T-Mo) running firmware H81120p, ARB3. Doesn't seem to be much that can be done with it as far as rooting. It also has no stock recovery, only boots to system.

you did follow this official guide right? it unlocked mine after a few angry moments
http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
use minimal ADB https://forum.xda-developers.com/showthread.php?t=2317790
Only way to boot twrp later is to use fastboot with ADB, recovery with buttons doesn't work.
if the device wont boot a rom use adb to get back in recovery.
if you use bank apps, install magisk before installing rom, do not get SU

Only problem is that the info linked to above applies to ONE G4 variant only - the H815 international model. The rest of us are SOL. The bootloader on US carrier G4 - AT&T, T-Mo, VzW, etc (most later firmware revisions for G3 as well) models has been nailed down. The only exception is a G4 with ARB <= 2 can be hacked with UsU in order to root it and install a custom recovery.

Tmo is very easy
Go to dev options and enable adb
Then run "adb reboot bootloader"
Once there, run "fastboot oem unlock" and voila, you have an officially unlocked bootloader with no restrictions related to UsU
Please be aware the above will factory reset your device

Do you know anyone who has done it with H81120o or later? I've seen posts for two yrs about doing it that way, but I don't remember reading about it being done on 20o or later.

Why v20o
Remember, this has nothing to do with UsU and therefore ARB etc doesn't matter
Edit: ps there are loads of H811 users in my Lineage thread and the other ROMs too

Got it. Guess that it makes sense. ARB prevents rolling back to earlier release than 20o, I'm ok. Will try the BL unlock today then.

I actually managed to get my LG V20 F800L into same situation after messing up my rooting process.
First i was stuck at logo and factory reset did nothing. Bootloader was working then.
Then i downloaded new firmware through "Download Mode", and after that i lost access to bootloader.
I know the phone model is different, but process seems to be very similar for all LG devices.
Trying to troubleshoot that atm, if i'll have results i'll post them here.
P.S. I know original poster long left (probably after throwing phone into a grinder), but maybe for someone with same problem as us in the future the info will be useful.

Ok, now i have to reply to my own post, since i believe i understand now something important:
LG phones usually dont have bootloader open to access. Until you use some exploits to do so.
I did not know that at the time of writing that reply.

Do you have more details about this? I seem to be in a similar situation than you and I'm struggling to make it work.

What exactly can I do with a NASH in EDL mode?

I have an XT1789-01 Verizon locked bootloader model Moto Z2 Force and I was successful in getting it into EDL mode (Qualcomm 9008). Is there a way I can flash TWRP with this? What exactly is possible with this? Thanks

the tmobile and at&t versions are the exact same model so if we get a phone to switch into this mode it may be possible to load it as a retail/tmobile version. im sure the verizon version has a similar issue as the at&t with a locked bootloader.

Well I'm trying to get TWRP flashed but I don't know how with EDL mode. It would bypass the need to unlock the bootloader if so. We could just flash a whole new bootloader from EDL, but I don't know how.

If you share it maybe someone can figure it out for you

I was curious if there was a way to boot into edl mode, obviously you can brick it there. I have a few leads as to how it can be done, but I haven't pursued them as edl isn't a necessity for me and I don't want to find myself in a position that I can't get out of without redoing everything. I imagine if I ever borked my phone I might delve into it a bit more. I thought edl might offer a solution for those who aren't bricked, but find themselves with a false lock and unable to flash anything.
Mainly though I don't like your approach, wanting help but not offering help, that's not what XDA is about. I get it though, AT&T and Verizon has a bounty for unlocking their bootloader and edl might offer a step in that direction, but there's a lot more to it. I'll give you a hint though, there is no recovery partition on this phone. Good luck.

yeah i figured that much, chcecking the vzw default firmware shows boot.img and bootloader.img, im assuming boot is where twrp is installed.
So getting to EDL mode was suprisingly easy and stupid, but it is for sure 100% EDL mode.
abd reboot edl
that's all. Granted I haven't updated the phone in a while, Ihave December 1 2017 security patch and oreo 8.0.0.
since this information is now public i think it should be clear not to update the phone from now on.

Hi
I have 5 x Moto z2 strength is I would like how you operate EDL Emergency DownLoad mode.
# abd reboot edl -> OK
The phone goes off (apparently ...) And now I miss the tools to interact with the phone.
How did you do ? What tools? Which orders?
thank you in advance

Need help unlocking my Note 4

Hello,
I have a Sprint Galaxy Note 4 I'd like to unlock. I called sprint and got the unlocking code. I was to wait 72 hours for the phone to be fully unlocked. Then, I needed to swap my sprint SIM with a different network SIM, and the phone would prompt me to enter the code, and that would be it. Unfortunately, I received an email with the following message:
Letting you know your CPO SAM N910 WHT SNGL on line XXXXXXXXXX cannot be
unlocked due to programming restrictions associated with phones like
yours that were manufactured before February, 2015. You can try
providing your master subsidy lock (MSL) code XXXXXX to your new
carrier to find out if it will work on their network.
Keep in mind we can't guarantee your older phone will operate correctly
on another carrier's network. Each wireless provider determines whether
or not they will utilize the MSL code to reprogram a phone for use on
their network.

I put a different SIM in my phone, boot it up, and I get an invalid SIM error, but the phone does not prompt me to enter a code.
I have read and seen multiple Note 4, including the Sprint variant, being unlocked. Does anyone know what I need to do to unlock it?
Thanks

Thanks - it's kind of hard to follow the instructions. It's unclear what he is doing.
It would appears that you first place the phone in download mode. In his instruction, he attempted to do that, but the phone rebooted. Is this a necessary step? Then he put the phone in recovery mode. But after that, he doesn't show you want happens. He simply moves on to unlocking a different phone. Is simply putting the phone in recovery mode unlock it? I doubt it... do I click on the Unlock button while in download mode to unlock it? It's not clear

Follow these steps exactly
Before you begin you must have samsung usb drivers installed in your windows pc.
1 download cdma yemen tool that i mentioned in my earlier replies.
2 put your phone in adb mode by dialing ##3424# and choose adb+dm (very important)
3 reboot device
4 open tool and connect your device via usb cable (WATCH OUT CAREFULLY FOR ANY POP UP WINDOW ON YOUR PHONE YOU MUST ALLOW PERMISSION TO CONNECT DEVICE WITH TOOL.
5 inside tool click on port/adb and select your device.
6 choose your correct model N910P of you have Note 4 sprint.
6 click UNLOCK TAB in tool and wait until your device will reboot automatically.
thats it.
After reboot hopefully you have permanently unlocked device.
If your device successfully unlocked then dial ##3424# and select mtp+adb back to normal.
The guy is showing in video all the stuff that this tool can do so dont go to download mode or recovery or anything because that's for removing frp lock and other stuff.
Let me know if it worked for you.
By the way if you are on latest QI5 firmware i am not 100% sure this tool will work because QI5 has latest bootloader/modem and it's not easy to unlock.
If this tool did not work for you let me know i have workaround.
Good luck

I am on QI5, and I didn't see a adb+dm option. I did see a DM + MODEM + ADM option under QUALCOMM USB SETTING (see attached screenshot), so I selected that.
The tool says Unlock Done With out Root... but it doesn't appear that the phone was indeed unlocked.
What's the workaround you have?

Yes DM+MODEM+ADM i was meaning.
The workaround i have is you have to flash Twrp RECOVERY and have to flash "ENG ROM" DONT FLASH ENG BOOTLOADER OR BASEBAND YOU WILL END UP UNKNOWN BASEBAND AND NULL IMEI.
Flash the rom from twrp and Also you have to flash supersu.zip to get full root with eng rom.
after that you have to use tool "Z3X SAMSUNG TOOLS PRO v27 or higher"
I cant share links here on xda for z3x because its heavily paid tool but if you search on youtube "z3x pro cracked" you will get 100s of videos with links to download.
HERE IS THE LINK FOR ENG ROM BY @freeza thanks to him.
https://forum.xda-developers.com/no...leakmm-sm-n910p-touchwiz-marshmallow-t3327350
After flashing eng rom the rom will take 35 minutes to boot so be patient and wait and also make sure battery is fully charged.
After that enable DM+MODEM+ADM as i mentioned earlier and you can unlock from z3x domestic use for american sim or unlock for international sim use.
Once phone is unlocked you must have to flash QI5 stock firmware via odin and do factory reset from stock recovery and dont worry the unlocking will stick permanently.
I personally did this method on QI5 ON my own device and it worked just fine.
I REPEAT DO NOT FLASH ENG BOOTLOADER OR MODEM OTHERWISE YOU WILL SCREW YOUR DEVICE COMPLETELY.
Cant explain more you got the idea i guess...
Good luck.

Btw try first the cdma yemen tool to.unlock with this rom with root. Maybe it can work.

It appears that I am not able to install TWRP... I install it via Odin from AP, and the install is successful. But when I try to boot into recovery, I get the stock recovery....
I tried TWRP 3.1.1 and 3.2.3... same thing. What am I not doing?

Open odin and uncheck auto reboot in odin options
Choose AP and flash twrp
After Odin shows pass remove battery
Insert battery and Boot straight into twrp by volume up+home+ power
If your phone reboots after flashing twrp the system overwrites the stock recovery over twrp thats why you are losing twrp so do not reboot system after flashing twrp.
Once you booted into twrp then if will stick permanently and stock recovery will never show up.
If i was helpful then consider hit thumbs up on my replies.

Thanks! It took a while with multiple flashes, but I think it is fully unlocked now. I am able to put a Verizon SIM card in it and get no sim card error message.

Usure if anyone still using this. But I just got my phone unlocc using it on crikket/att. Unsure why you got a 7 wait but I was able to make phones and use internet immediately after I unlocc the phone. The only problem I'm facing is being able to use 4g o the phone.

You won't get 4g/lte because n910p sprint note 4 is CDMA model and you need GSM model for 4g on at&t/cricket.

Root SM-G960W android 10 possible ?

Hello everyone thank you for your time it's been a couple days i'm doing reasearch on how to root my galaxy S9 (canadian) and i'm hitting a wall everytime and some post a far too old to be considered.
So my question is without the OEM unlock option in developper options am i doomed to not being able to root my phone ?
And yes i tried the trick with setting the date manually one month earlier but anyway my phone is more than 1 year old so i'm way past the 7 days delay.
Isn't there a way to unlock it with a computer via USB debugging mode ? ( juste an idea like that i know pretty much nothing)
Any clear answer would be greatly appreciated.
Thank you for your time

OEM Unlock option is pretty much like the gate to unlock your boot loader
if your phone doesn't have the option then that could be cause by some factors like,
- either you can't unlock (I believe there are few versions that factory lock which mean cant be unlocked)
- or you have faied to modify your phone, which you have to wait like 7 days to be able to modify again
That all I know, maybe anyone can correct me if I'm wrong

okay i understand more what OEM does thank so as long as i can't unlock it from the inside no modification can come from the outside

You should read through this thread. It has some options that may interest you. The Canadian SM-G960W S9 is definitely boot loader locked that makes it "normally" not able too install any custom ROMs or boot loaders. The good thing with it is that it doesn't trip KNOX!

My G710VM is somehow a V35OULM -> No upgrade possible via LGUP

Hello Wise men and women. I recently bought an LG-G7 ThinQ secondhand for what I thought was an excellent price. When I got it home and looked at the phone details I noticed why. The phone is rooted, bootloader unlocked of course, with Magisk and no custon recovery, operating on 8.0.0 firmware. I knew all of this when I bought the phone and had no issue with it figuring I would just upgrade and take it from there. The model says LM-G710 according to 3cs, 6.1 screen, G7 Boot image, so I am confident it is a G7. Under Hardware info and when attempting to use LGUP or LG MSTool however, it is seen as LM-V35OULM. In Terminal the phone is seen as Judyln, but just about everywhere else judyln_lao. The firmware is currently V35_11g, and I would really like to upgrade it to 10 when all is said and done but right now I have reached the clueless stage. Any ideas on how to go about fixing this problem?
On a side note the IMEI, MEID and ESN all read goose eggs. I was able to get service to the phone and even register it with LG (unbelievably) so at this moment I really don't care unless of course that would keep me from upgrading. Not sure if its pertanent but it seems odd to me.
Also, I am not a developer but would classify myself as a phone nerd and I'd like to think I'm not totally helpless here. But, that has been the outcome of every attempt to fix the problem up to this point. Out of curiosity I even tried to upgrade using V35 firmware figuring it was worth a shot but that didn't work either. LGUP likes to remind me that nothing seems to match and that I am a moron for not looking closer at rhe phone before I bought it. Live and learn I suppose. Hopefuly.
Thanks for any help anyone can offer.

I'm only guessing but it sounds like one of the abl_a or abl_b partitions have the v35 engineering fastboot installed perhaps?
Can you get into fastboot? Does the phone display a LM-G710... model in fastboot? If it displays a V35 model than thats why
The v35 gets put onto the abl partition when people want to unlock the bootloader via the EDL (9008) method.
If thats the case you need a G7 abl partition copy. If you get into EDL mode and reflash either or both of the abl partitions and laf partitions you should be able to get download mode and then flash a rom using LGUP. (laf partitons contain the download mode)
I understand the bootloader is unlocked but if you read a G7 guide on unlocking the bootloader what I've been saying might be a bit clearer
