my phone model H901 21j
same issue . ihave h901 running on 5.1 update it via lg up to 6.0 20e then its bricked . pc read it as qualcom hs-usb 9008 . any help/ solution
Is there a reason this thread has been ignored? I also have a LG V10 H901 21J MM/6.0 stock firmware.
I have not as of yet flashed a .tot file to it, because I am not sure that the .tot files for other H901 phones is correct. I have heard different things, regarding this particular version, which I have heard is a Korean version of the phone, I am not sure if this is applicable or true, but apparently this may mean the phone has a different board than other H901s out there.
What I can say for certain is that I was unable to unlock my bootloader, due to the inability to reach Fastboot/Bootloader moder from this phone using any of the normal methods which work on my other LG V10 901. The procedures I have followed to get into Fastboot/Booloader mode are: (a) Shutting down phone; --> Pressing Power-Off, and Volume Down at the same time, holding for 5-6 seconds after the LG screen appears, which just causes the phone to boot normally, (b) running <adb reboot bootloader>, which again just boots normally, it does not go into the bootloader/fastboot mode; and (c) Power down /turn off the phone, once off, hold down Volume Down, while you plugin a USB cable into the phone(that is already plugged into a computer with good drivers on the phone), continuing to hold down the Volume Down until you reach Fastboot, again same results and this does assume that the USB cable is plugged into a computer with good drivers.. Just for the record for the methods listed that involve having the phone attached to the computer, I have tried this with the phones USB in both Multi-Media Mode, and PTP mode, without a difference being made, and it should be mentioned that I have successfully performed all 3 methods on my LG V10 H901 20L running stock MM, which was successfully rooted using the Dirtycow exploit. Yes, debugging is enabled on the phone, and although it does not effect getting into Fastboot mode itself, OEM UNLOCK is enabled.
If I could get into Fastboot on this phone, and get it unlocked, then I should be able to use the Dirtycow exploit in order to get temporary root, that would of course allow me to then flash TWRP recovery directly to the recovery partition, and solve the issue.
rabahallia I know that this is almost a year late, but can you tell me if your phone was unlocked when you flashed the .tot file, and if so, how did you go about unlocking it? Also, I can tell you based on the chipset that the phone runs, that you should be able to image a microSD card using a ROM designed for the phone, and then boot using the flashed sdcard image. If you are not able to do that, then can you tell me if now that your phone is bricked, is the phone turning on at all, or just not booting fully? Can you attempt to get it into Fastboot mode now, using the methods I described above? You will have the highest chance of success using the 3rd method in terms of being straight forward, and of course the fact that your phone is not booting again that involves: plugging a USB cable into your PC, then, shutting down your phone which is not a problem in your case with your phone off, hold down the Volume Down button on your phone, while still holding down the Volume Down plug the USB cable into your phone, and continue holding Volume Down until your phone reaches the fastboot/bootloader menu. If you are able to do this, and you DID NOT unlock your phone before you flashed the .tot with the modified recovery onto your phone, then unlocking the bootloader at this point may allow your phone to boot. To do this, after you have reached Fastboot/Booloader, you will use the command <fastboot oem unlock> wait for it to finish, and it should inform you that your phone is now unlocked, then you can reboot your phone using <fastboot reboot>. Please let me know if this worked, or if you still have the phone, if you could try this. I am interested to know if flashing the .tot to a phone that can not be unlocked due to inability to reach the bootloader/Fastboot mode, as you may have done, would allow that mode to be reached after bricking the phone, and if so, if unlocking the phones bootloader after the fact, fixes the issue. If this does not fix the issue, but you were able to reach fastboot/bootloader, then you should be able to reboot back into Fastboot mode, and then flash a recovery, which would in turn allow you to flash a new ROM to the phone. If anyone else out there has any information SPECIFICALLY ON THE 21J version of H901 stock MM, please provide any information you may have. Or if you have any information about what board is running on this phone, if it is not the same board running on every other version of the H901 such as the 20J, 20e, 20L.

Okay, so i am using a xperia z2, cant rmb the version of the firmware, but i successfully rooted my device so i went on to try and flash cm11 onto my device. However, upon flashing cm11 and gapps into my phone through dual recovery i was no longer able to boot up my phone. Holding the power switch causes the device to vibrate, like perhaps every two seconds, but does nothing meaningful. Holding the powerswitch and the volume up key boots into fast boot, which is just a blank screen, but with the blue led that i read on the internet meant fastboot. Problem is, I am unable to get windows to install the relevant drivers for S1 Fastboot as it is displayed on my device manager window, and nothing i try will help. Ive downloaded usb drivers from numerous sources, including but not limited to flashtool, and nothing can get the fastboot to be recognised by the computer. Kindly advise on what i could do to restore my phone please! any help is greatly appreciated!!!!
I live in Singapore and i understand that bootloaders are by default unlocked? I'm not sure if i have to install any form of kernel , but i have a feeling this may be the cause of the problem? Please be kind, I am new to this entire rooting business. Once again any assistance is greatly appreciated!

Folow this to unbrick your device
You need an unlocked bootloader to flash cm11, no bootloader comes unlocked
There is unlockable and non unlockable
Good evening, I have in my hands a smartphone lg p778g does not pass me the logo to light following a simple copy of the folder whatsapp internal memory to the microsd (it was blocked after you copy and to restart it and did not initiate more ... it stays in the LG logo when turned on and there does not pass.
I tried to hard reset with vol (+ or -) buttons + home + power but rather than get out the menu of recovery I get the doll android slept with a triangle exclamation and there is no way to enter the menu that tightening no buttons.
Then I looking for information online found the utility tool flash, did all the steps as marked, I installed the drivers perfectly, the PC detects me the phone without problems, but always in the middle of the update (put the mobile mode s / w upgrade ) 50% program lg cancel the process by saying that there has been an unknown error and try try again by disconnecting and connecting the mobile, but no way, I give retry to to try again and again it hangs at 50% and I jump the error screen again.
I wonder if there is some other program where you can do the hard reset this phone than by the official LG utility, or by microsd.
The operating system used is Windows 7 64-bit, disable the Windows firewall and antivirus and run as administrator utility tool flash lg 2014, but always the same. I also tried running the utility lg mobile support tool directly to you directly seeking the most updated for lg p778g firmware, but it's the same as using the lg flash tool 2014, the 50% of the upgrade stops and gives me the message error.
A greeting and I hope you can help me, I need the phone !!
We'd need someone with a p778g. The problem may be be caused by the special branding of the phone, or an encrypted bootloader. Or the internal flash got completely cleared, partitions and baseband rom, which means a full brick. Otherwise flashing stock in D/L mode should work, even if anything else fails. But this goes mainly for LGs official tool working online. With the LG Flash Tool 2014 i had also problems.
I think both tools have to ways to perform the unbricking. Either with the phone put in D/L mode by the user (if Fastboot don't work on the PC), or by recognizing the phone (but with a still running system) via ADB, then auto-switching to Fastboot. And you should also be able to attach the phone when it's already in Fastboot mode. The latter methods don't work on both my systems under Win10. When my desktop pc had been upgraded to 8.1, i performed all servicing of the L9 with my netbook, which was still on Seven.
My last unbrick was months ago, and i don' t know what happens at 50%. It's something important, and knowing it may help to understand the nature of the problem(loss of contact between phone and pc before the actual process starts, errors during flashing...).
It could be like this:
-phone seems to get recognized by driver&tool, that is good
-image gets downloaded(only with the official tool)
-image gets temporarily extracted on the pc(both online and offline). I fear that by completing the extraction the 50% mark is reached, and that no actual writes to the phone can be performed.
And LG's stock recovery, which calls itself "service mode" or "s/w mode" can be mistaken for D/L mode. I'm talking about the D/L mode, which is also present with a custom recovery, but theoretically D/L mode, S/W mode and Fastboot could be used for unbricking

To begin with, I was trying to unlock Lg sp200 tribute dynasty phone , I was told that flashing lg k8 plus x210mula firmware will do it. Everything went well during flashing process using chip erase command on lg up software until it didn't.
The phone stuck in lg k8 plus logo, at first I went to download mode but then I tride hard reset way by using recovery method but everything went bad after that. I had been stuck at black screen since then with a message saying [LGE] [Image Recovery] op_image : 0 API Support : 3 and no ability to go back to download mode .
When plugged in, the phone was recognized by the computer for a few seconds beep and then disconnected after the message appears.
I tried lg up, lg flash tool and even plugging without battery using volume up method to get into download mode but no luck.
Now I need a powerful tool to get back to download mode to flash new firmware that I got recently.
hi
i too have a bricked lg phone mine is a fortune 2 lmx210ma. i was trying to flash a tecknight rom and when it erased the partitions it went dead and never came back. is there a way to fix this?

Got a queation. Have you plugged your phone into a pc mac or linux machine to see if it registers. It being a qcom device it might show up as hsusb 9008 or qdl mode. If so you might be in the same boat as me. If it is check out QPST or QDL on linux and do some research. Im going to try to use qdl to revive my fortune2.
Worthy to note before attempting any kind of drastic procedure like exchange of firmware do extra research and make sure device hardware is compatible with the firmware you are trying to flash.
Some phones like the LG LMX210 variants called CV1 are pretty much interchangeable running the same hardwares. But there are a couple like my ulma that run mtk. Flashing mtk with qcom or vice-versa cause really bad. Thats not what i did i was just tired and wasnt paying attention to my procedure list and well you know it happens.
During a flash, the connection to my V30 was interrupted for some reason, probably a worn out USB cable getting knocked into and shifting around in the USB C port. Ever since then, the phone refuses to get past the bootloader or recovery if I hold down the proper keys.
I have used a modded version of LGUP that I originally downloaded to help frankenstein this phone to refurbish, upgrade, even chip erase (this does get rid of the IMEI and other important numbers but since this phone is no longer my daily it's fine if it has no IMEI to me, I'll be honest I'm not sure if chip erase gets rid of any other stuff that should absolutely never be touched). The phone still boots straight to the bootloader. I have also tried flashing custom recoveries (such as TWRP, this has been successful) and installing .zip format roms to the device through the recovery (not successful, still boots straight to bootloader without fail).
So uh... did I manage to brick my V30? Or does it sound like there's at least a bit of hope? Any help would be greatly appreciated, I really wanted to use this thing as a sort of glorified iPod because of that magical dac.

You've tried going into download mode manually, use Dev Patched LGUP in Refurbish mode to reinstall US998 20h KDZ?

I've entered DL mode manually and I'm using the dev patched version of LGUP. I haven't tried that particular KDZ though, I could give it a shot for the hell of it. Anyways thanks.
Also, would using Qualcomm download mode work? I'm fine with opening up the phone to trigger the contacts, I just don't know if I'll be able to do any good once in that mode.

First, you don't need to open the phone to enter QDLoader / EDL / 9008 mode:
With the phone connected to a PC (you don't need any special software loaded, just the USB connection), and with the phone powered on and unlocked, hold vol +, vol -, and power to shutdown the phone. Keep holding them till you get a countdown on the screen. The second the countdown completes, and the screen shuts off, let go of power, keep holding vol -, and start tapping the crap out of vol +.
If you have problems getting into recovery using the key combo, this is at least 5x as hard to get it right. When you do, the screen will be blank and the phone will show up in your OS as 9008. Example in Linux:
Code:
Bus 001 Device 015: ID 05c6:[B]9008[/B] Qualcomm, Inc. Gobi Wireless Modem ([B]QDL mode[/B])
To exit 9008 if you decide not to flash anything, just press and hold vol - and power until the phone reboots.
Now, with that said, you still need the firehose. I haven't looked for it yet because I haven't needed it, but there is a V30 (all models except the H932) firehose out there somewhere. Also, of course, you need QFIL.
Now will this help -- as long as there isn't a hardware problem with your phone, you can do anything you want in QDL mode with the understanding that signatures are still checked, so you can only flash V30 (non-H932) firmware. If flashing a KDZ doesn't fix your problem, you must have a problem with a partition that doesn't get flashed from a KDZ. Unfortunately, if you don't know which one, it will be trial and error and you will need a complete dump of a V30 minus EFS.

Pretty much. Fastboot behaves normally and it does reboot with the fastboot reboot command but it just ends up right back at the bootloader unless I use the key combos required to get into LGUP DL mode/recovery.
That's great info Brian. Always thought opening phone, disconnecting battery ribbon, and shorting test points are only way to force qdl 9008 mode. Thanks for this info :good:
I was trying to flash lg-k350n with LineageOs and make a whole bunch of idiotic deeds, so currently I'm felling like dying is the best option for me.
1. I've used this tutorial: .getdroidtips.com/install-custom-rom-using-twrp-recovery. It clearly says that this ROM is for Android 8.0 Oreo, while mine is Android 6.0 Marshmallow. Nevertheless I've downloaded ROM lineage-15.0-20170913-Unofficial-MT6735-64-bit.zip. For some reason TWRP mentioned here getdroidtips.com/lineage-os-15-lg-k8-8-0-oreo/ did not wok for me but I've googled a bit and found something called TWRP-recovery-for-LG-K8.img which worked (not by fastboot flash TWRP-recovery-for-LG-K8.img since this TWRP appeared to be to big but simply by fastboot boot TWRP-recovery-for-LG-K8.img).
So I just did:i
turn on debugger
turn off oem lock
adb boot bootloader
fastboot boot TWRP-recovery-for-LG-K8.img
Feeling happy that TWRP loaded nicely I had not done any backjup and just wiped system as suggested here: lineageos.org/devices/h990/install. Then I've tried to installl the Android 8..0. ROM with obviously did not work. And I've got left with a TWRP working and then I've put the last needle in my coffin - I've rebooted hoping that some hard reset or recovery will fix things for me.
So now I have a phone which I'm able to put to recovery, but it does not recover anything. The phone just go dead after such a recovery.
I cannot put it into fastboot mode, if I could, I would just run 'fastboot boot TWRP-recovery-for-LG-K8.img' and at least had a chance to google a bit for maybe a vanilla ROM or anything working, which I could've later installer.
I've seen that there is a way to put the phone into download mode when it will download stuff from S/W "LG Bridge", bu I don't have Windows and haven't yet tried in virtualbox.
Is there any way to unbrick the device? Please help an idiot!
Sorry, you have to find a Windows box I'm afraid, LG is only offering Windows software for flashing. But chances are quite good that you are able to revive the telephone that way. I have bricked my phone as well but was able to unbrick it this way:
Go to www.lg.com, choose your language, select download, software and firmware.
Select smartphone, Android smartphones, K-series and your model number. This is only to come to the download site of LG Bridge, I guess it's not really important to choose the precise model!
Download LG Bridge, install and start it.
Let it update itself and the USB drivers and keep the software running.
Switch off the phone, press Volume up and keep holding that button.
Connect the phone with via USB with the PC while still pressing Volume Up. The phone should be recognized by the PC (install USB driver) and by LG Bridge (watch the status line to the left, it should show the phone type and USB)
The phone should automatically switch on and show a download screen (yippee!)
Select the second tab "software update" and then click on "correct update error" in the lower right. It should automatically download the correct firmware from the internet, so this is rather fool proof!
Click through it and this should start the flashing process, at the end the phone will automatically reboot, ask for the PIN, etc.
Unbricked!!!
Above instruction worked for me on a completely demolished phone. Lineage OS, changed FS, root attempted, I almost though that's it, but no, it recovered, thumbs up.
I haven't tried in Virtual Box, so I cannot tell if this is working. But you've got nothing to loose, right, so why not try it?

your phone cannot be trusted loooooop, cannot goto download and fastboot mode...
If you don't manage to enter download mode you have probably indeed bricked the phone. If what I've written above doesn't work for you I know of no other way to resurrect it, sorry.
This is because you cannot burn TWRP to the Flash plus there's no tool available to bootstrap an LG phone with a completely naked or corrupted Flash. There must be something like that, because a freshly manufactured phone has by definition a naked Flash.
With Samsung phones you have Odin and with it it is possible to burn a software to a completely dead phone. So it is almost impossible to hard brick it. With LG unfortunately it is different. Plus this phone is somehow crippled, it has only a very, very limited amount of Flash. So I would recommend to not care for this phone anymore, it's not worth it, and instead get a current one with a decent amount of memory.
