A few years ago, I ended up bricking my LG G5 RS988 variant, by trying to flash a stock rom, so I can remove the root, and everything else to give the phone to my brother. However, by flashing the wrong rom, I ended up being in a loop where the phone would start up, and 2 minutes into the set up screen, it would restart and be in a never ending loop. I remember trying to fix this problem, and made it worse by probably erasing access to my twrp recovery(can't access the recovery anymore don't remember what I did), then I gave up. I decided to try again to see if I can bring back this phone from the grave so I was wondering if someone could lead me into the right direction. I have the uppercut tool, the lg flash tool, and the drivers. Also in the uppercut tool I do see the version of my phone is RS98821d and I am trying to flash a RS98811c_00_ARB01.kdz. Also another thing to note, my phone automatically boots into firmware update mode(download mode I believe?). Also I have looked into the all in one lg g5 forums, and other forums of restoring their phones, but nothing works with what I tried on my rs988, is their someone that can lead me to the right direction?
Can you do this when you start the phone to get into fastboot?
Code:
adb reboot bootloader
If so, you should be able to get TWRP back up and running:
Code:
fastboot flash recovery [path to twrp image on your pc]

Hey everyone, so I woke up Saturday morning to a wonderful surprise, and am just getting around to letting everyone know and maybe throw their suggestions my way!
Device: Tmo LG V10, H901
Recovery: [TWRP] Recovery: V10_H901_pplus [V3.0.2-0] [08/16/2016]
ROM: [ROM] [STOCK] [H901] V10_H901_V20J_Stock_Custom_2e [08/15/2016]; V10_H901_V20J_Stock_Custom_2e-signed
Root: Systemless Instructions - How to - 08/08/2016
Xposed: Systemless Xposed, see root guide above
Friday night, I was using my T-Mobile V10 like normal. No recent modifications, no new apps, adjustments, etc... Plug it into the charger and go to bed for the night. No issues right?
I wake up Saturday and the screen is blank. The phone isn't responding to the power button, so I hold the Vol-Down+Vol-Up+Power down to reboot it.
The phone won't reboot. So I pull the battery, and throw it back in.
Phone hits the LG logo, yey!
But it never moves from the LG logo
So at this point, I try booting into Recovery (TWRP) and the phone seems to not be responding to my button commands. It hits the boot logo and never does anything else.
I tried to boot into Download mode, nothing, just sitting on the logo.
After messing with the phone, with and without a USB cable attached to my laptop, I finally get the device into Fastboot.
In fastboot, I can run commands, but since I am on V20J, I am unable to flash or boot TWRP
I was also able to get into download mode when plugged into my PC only.
So down below, I will go over all the stuff I have tried.
Modes I can enter-
Fastboot
Download Mode (USB)
Stuff I tried-
LG Bridge Update
Update says it succeeds
Still does not boot
When I reconnect LG Bridge again, it says an error occurred and wants to update again
Direct .img flash via Fastboot
Using the steps from this post
Unable to flash, FAILED (remote:unknown command) due to V20J I believe
Flash V20J .tot via LGUP
It seems to flash successfully, but the phone still doesn't boot
So I left for the T-Mobile store Saturday, phone not booting, just stuck on the logo.
They are Warrantying the phone, so I am just waiting on a back-ordered replacement now.
EDIT: The Plot Thickens....
So I thought I would fire up the phone this morning, maybe try some other updates/flashes again, maybe something will happen.
Now I cant even get into Download Mode (USB) anymore.
It shows Download Mode on the screen, then the phone just reboots.
Additionally, on first boot I received some sort of error on the screen, but it went away so fast I couldn't read it.
Now I can't get that error to come back for the life of me...
I am just so confused now. The phone has a mind of its own.
My brother had 2 V10's that did that. Replaced under warranty.
Exact thing happened to me back on pre mm.. I got into twrp after many many many tries.. Flashed an old back up and phone booted. I was able to get into the phone long enough to relock bootloader before it started the same crap... Warrantied it out and that was that..
Yikes. Making me scared once this warranty is up.... Would hate to just lose a phone randomly for no reason!

Can you plz guide how you relocked bootloader? I am rooted and using custom rom. Should I first install stock kdz and then give command via fastboot or it must be done with root? Thanks

You can relock via fastboot using the command
Code:
fastboot oem lock
Use the below command to check your current status
Code:
fastboot getvar unlocked
I believe it even says these commands on the screen when in fastboot.

Thnks I jav read these but need to know if i should b on stock rom before locking or what? And any known issue while trying relocking it?
I don't know if anyone else has posted anything similar, if they have, please point me in the direction of their thread and I will piggyback off of it. I have a LG G Vista VS880 that I rooted with Kingroot. My next step was to nuke the LAF, go into fast boot and use fastboot oem unllock to unlock the bootloader so I could install custom recovery. I got as far as nuking the LAF when I had to stop and fix dinner for the kids. When I got back to the computer I forgot that I hadn't unlocked the bootloader yet and flashed the custom recovery and a magisk patched boot.img using flashify. Now it will not boot into system or recovery. I can get it to boot into fastboot mode by holding the volume up button while plugging it in but all my fastboot commands are locked. I have searched the forums and have found nothing except some info on getting into QHUSB mode by shorting out the test point but that post was for the G3 and when I took off the back plate the configuration was different and I didnt want to mees my phone up any worse than I already had. I just want to get back to stock and start over. Can someone please help or at least point me in the right direction?!?!?!? I would welcome any assistance!
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.
Hi guys been spending all night trying to figure out but seems nothing is working. HELP! I know i can get it to work.
So tried to root my A2017G previously but saw all the horror brick stories so ended up just doing the multiple OTA updates via SDCARD upgrade.zip and finally ended up with OREO BO3 version. running fine except for ridiculous battery meter levels playing up but just kept it charged most of the time.
1) at first I tried to check bootloader unlock status from fastboot. But somehow unable to as fastboot is not there! So i thought maybe fastboot is corrupt (stock recovery options ok / also power plus down gets stuck in FTM mode (easy to reboot with adb command) So unable to check bootloader (i am thinking its probably still locked)
2) so got latest version of TWRP 3.3 something and flashed it --> result in phone black screen but detectable (I assume in EDL mode.) '
3) Tried to flash Nougat B10 EDL with EDL tool (working now but after everything is ready to flash it says"" 13:02:38: {ERROR: WritePort:5164 Could not write to '\\.\COM8', Windows API WriteFile failed! Your device is probably *not* on this port, attempted 100 times""
4) MiFlash unable to read hello packet. But i tried pressing power and connecting quickly and suddenly starts flashing B10 nougat EDL ROM but doesnt complete with a "function: sahara_rx_data:237, unable to read packet header" error. Should I be using a stock rom with Meta-INF folder rather than the EDL version? Also should i be flashing OREO stock rom rather than nougat with MiFlash? or it doesnt matter?
5) tried the DFU tool initially qualcomm and com8 detected but says disconnected. (so its in EDL probably but somehow still disconnected?
So currently
1) trying to let the phone battery run out, though i doubt its any use as i probably bricked it installing twrp without unlock bootloader on OREO.
2) Also downloading Oreo stock rom to try and flash with miflash.
Any help or point to some discussion i missed would be helpful thanks. Just wanna get root and GPS tools running so I can let the kids catch some Pokemon without GOing outside.
Seems like the battery had to run out first. Then it started recharging . After about 5 mins I just pressed power button without up or down. Phone rebooted nicely back into Oreo. PhEW... Then i used a stock 2017g EDL for nougat B10 (7.1.1) and flashed with Miflash by going into proper EDL (used ADB reboot EDL command)
Ok some more small hiccups along the way but being able to access EDl i managed to flash TWRP 3.2.1 and then load it up and flash SuperSU for root.
Now to read the threads on how to get rid of the bootloader unlock screen as well as load in the battery saving scripts.
I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.
There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.
