So, I have an E971 that has no working volume buttons and cannot be put into download mode.
Scratch the below info as now it is now either worse or better
Worse is that I don't have ADB or fastboot anymore. The phone flashes the Google logo and that is it. It shows up in dev manager as LGE Android MTP Device and COM ports 12 and 13 BUT that is all.
LG Flash Tool 2014 and others try to install but all fail at 4% into the actual flash process
I know the phone boots into TWRP but the screen goes off right after the TWRP logo so obviously the screen is OK. TWRP keeps on running in the background and I can ADB into the phone. Only other connection option is fastboot.
I have flashed new recovery through fastboot but the screen still turns off after the recovery logo but I can access the phone with ADB at this stage.
Were this a Samsung phone I could simply adb reboot download, but this is not available.
Where do I start? Help!
With much luck I took the phone apart and now have working volume buttons and a running OS but now have an IMEI of 0
Hi guys, so my problem is I was installing a new rom on my rooted D855. everything was going along fine but then the process stalled. I left it running for 15 - 20 minutes but it was still on 33%. I tried holding the power button in desperation which shut the thing down. Now when I try to factory reset it goes to the prompt screen, I answer yes, then it asks me to confirm. from there however it goes to LG splash screen and eventually a black screen with Fastboot mode started. -reset- portcharge -reset- portcharge fastboot: processing commands in the top left corner. That's it.. If I try download mode it goes to the download screen and then to the black screen as described above.
Sounds pretty ordinary but if there is an answer out there I am sure one of you guys will know it.
TIA
i had some similar other issue and the only way i got out of it, is by using the lg flashtool 2014 and the KDZ file appropriate to your version
there is a thread with a step by step instructions.
you launch the flashtool, then insert the kdz file (original stock rom) then you put your phone into download mode (making sure in windows/controlpanel/devicemanager/ports - comp port 41 for the device driver)
you press volume up and plug it into the pc, the pc sees the phone and it starts reflashing the custom rom to your cell.
i presume that as soon as your download mode is working by flashing whatever command is corrupt and makes your phone black should be bypassed by then
i hope it helps - look for the thread how to flash the lg
Thanks I'll give it a shot. Not sure device manager is seeing it properly. I'll have a play and see. Thanks again for the reply
O.K here's the thing, my phone is seen in device manager as a Samsung Android Phone. Under the details tab it shows it connected via USB Modem Phone ADB Port. There is no option to change the port to 41. Anybody who can help I would be very grateful......
Hello,
I seem to have really messed up my G3 and after days of research I have not been able to get anywhere with it. I've read posts of people having similar issues, but their solutions do not seem to work for me.
What I tried to do is flash the ROM, starting with TWRP. After installing TWRP and rebooting I was getting the "no command" message on the screen. I believe (this was days ago), I used ADB to remove laf and reboot the phone (for some reason I could not back it up). The phone rebooted in fastboot and it has been downhill from there.
No download mode. When normally started the phone just hangs on the LG logo. Vol- and power gets me to the "Factory data reset", but if I do that, it flashes "erasing" for a second and it goes back to the LG logo screen.
I can get to fastboot, however, any command that I enter in CMD or Linux terminal just shows up on the phone's screen and it does not do anything. Fastboot devices shows the device as "????????" in Linux and as "?" in Windows. I have tried multiple drivers for Windows.
I tried BoardDiag (3 or 4 different versions running as admin) and shorting the pins, but any time I try to run the checks, I get an error - "No response from device" or "Device was not found in dload trying flash programmer"
I also tried SmartBootDiag, but once it detects the phone, it does its checks and it disconnects the device, without giving me an option to flash anything. Looking at the logs, it does not find any anti-rollback issues.
Any suggestions would be greatly appreciated as I am not sure what else to try.......
Thank you.
Anyone??
So Here are the steps
1. My bootloader got unlocked.
2. I Installed factory preloader and lk images.
3. Rebooted to Fasboot and flashed TWRP 3.3.1-0924 by wzsx150 (the only Android 9 recovery that didn't get removed immediately after flashing and rebooting for 1st time to get to recovery).
4. Formatted Data, Closed AVB 2.0 and Signed TWRP.
5. Rebooted to Fastboot and flashed stock EEA Android 9 (11.0.3.0) from Global (11.0.6.0) and reflashed factory preloader and lk.
6. Rebooted to recovery, Formatted Data, Closed AVB 2.0 and Signed TWRP.
7. Using ADB sideload from Twrp Installed EEA Android 10 (11.0.2.0).
8. Rebooted into fastboot Installed Updated TWRP-3.3.1-1210 (by wzsx150).
9. Rebooted into fastboot and flashed misc.bin from same zip (according to bat file inside it should get flashed after recovery but I forgot.)
10. BRICKED. Booted to Redmi logo for 3 seconds and rebooted infinitely.
This type of brick in 4pda.ru according to google translate can be mitigated by letting battery drain and then enter DA download mode using SP Flash Tool.
I've Used the tool several time so I thought Okay no big deal.
So This is what I tried:
11. Pressed download button
12. Connected USB Cable to phone.
13. Device pauses a second (Probably for SP Flash Tool to respond) then doesn't enter DA (Unlike previous times) and screen brighten for a second or two but then turns off and repeats this process forever.
I've been using Drivers provided by Microsoft Update Catalogue but tried all the drivers on 'MTK Usb Driver v1.0.8' and 'Mediatek_Driver_Auto_Installer_1.1352.00' after disabling Driver Signature Enforcement. but even though drivers are installed they don't get loaded and after force installing them in add legacy drivers they are their but have yellow triangles and their Location lists as 'Unknown' and status as 'This device cannot start. (Code 10)'. Tried Removing them after adding them as a site suggested but that didn't work either.
I learned the hard way to never mismatch partitions with this phone. I thought having the factory preloader and lk1/2 would protect me but no.
When you say brick, do you mean you have a completely black screen with only the notification LED turning on when you plug it in?
Grab a bootable Linux image and use that on a USB stick to eliminate the driver issue you're having. Interface is identical

So I tried Ubuntu. Problem isn't from Drivers. It's because my Windows or linux didn't ever got a chance to enter fastboot so they can load preload drivers properly.
In Windows, Mediatek USB Port is the only driver that get loaded, and that for only an instant then it disappears in Device Manager.
In Linux according to this Tutorial everything is fine but SP Flash Tool gives me a " ERROR : STATUS_ERR (-1073676287) , MSP ERROE CODE : 0x00. "
Based on this chinese site I should find my Vendor Id and Product Id specific to my system (or is it my chipset?) and then change some files but how do I get linux to recognize mediatek usb device first when It needs to enter fastboot for that to happen.
Is there any way to manually add it?
EDIT: So After some reading I realized that I have to get my phone to fastboot first to get the drivers recognized. In windows as far as I know there is no way for manually adding 'Location' to Drivers. what about Linux?
I think you're talking about a soft-brick and I'm talking about a hard-brick. If you can get to fastboot, it's a soft-brick.
Hold the volume down and power buttons simultaneously for 1min and see if your screen changes.
Don't worry about the Linux drivers, if your phone is in the correct mode, it'll work.
I don't think it's a Soft-Brick (unless Hard-Brick means even the display not turning up at all), Holding them for a minute with battery charged doesn't do anything. As soon as it boots back up it starts getting caught in Booting until Redmi logo and staying there for 2-3 seconds then reboots. I tried to hold Volume Down + Power for 3 minutes while caught in this bootloop but no fastboot. I'll retry when battery discharges again. first without usb cable attached then with.
Thanks for taking time to work this through with me. Nowadays with all service centers being closed it's really a nightmare to have something you need on internal storage and not being able to access it. First thing I'll do after this is to buy a 128GB SD card to store the important stuff.
By the way should I just use the Live Ubuntu or Install it to see if the problem is from being a live image.
When I hard bricked my phone, I didn't have anything but that white led when I plugged it in. If you have the redmi logo, should mean there is hope. I've only ever entered DA mode when I had a hard brick.
This might be one of those situations where letting the battery drop to 0% would allow you to access fastboot. MiFlash only works in fastboot and DA mode I believe. What happens when you hold volume up and power for a minute while plugged in to your computer? Run "ADB devices" to start the adb service first
I doubt it would make a difference live to installed, but it's your call if you have the time.
With Phone in Bootloop mode Holding Either Vl+ and Power or Vl- and Power doesn't make a difference.
With Phone Off and USB detached It's the same.
With USB attached Vol+ and Power for over 3 Mins result in Device Manger listing 'Mediatek USB Port' for as long as display remains 'dark but bright' (for 2-3 seconds then shuts down and turns itself back on). removing it when phone suddenly shuts down. when USB is detached phone remains shutdown.
With USB attached Vol- and Power for over 3 Mins result in Phone's Display Brightening for 5 seconds no device listing in Device Manager nor entering fastboot or being recognized by adb or fastboot (set on a permanent re-checking by a cmd script). then phone shuts itself down and back on.
LED situation:
With Vol+ and Power with USB attached LED when phone is Off is Fullbright. When Display Brightens It turns off.
With Vol- and Power with USB attached LED when Phone is Off Blinks Once Fullbright and then remains Semi-bright whether phone is on until shutdown and the Blinks Fullbright again.
I Live in Iran and with sanctions there is no way to pay anyone overseas. Unless they're willing to risk accepting cryptocurrencies from an Iranian , my only chance if I can't work it out is to wait till unofficial service centers here open.
Your phone only being detected for 5 seconds is supposed to happen. It checks for a signal from so flash and if it doesn't see it, drops off.
I'm not sure paying someone to remotely flash your phone will work if SP Flash isn't even trying or detecting your phone. With mine, it would detect and try to flash (red bar sitting at 100%) before throwing an error.
Try letting your battery die, if that doesn't work, maybe the test point mod will work. Otherwise, I think your only option is a service center.
Ok, so I’ve run myself off the road into a deep hole and am hoping someone can help me climb out and get back onto the correct path.
I have a Motorola Moto G7 Play 1952-4 (channel). My goal is to install TWRP, and LineageOS 18.1 with GAPPS. Root is not important at the moment.
Here’s what I did:
After successfully unlocking the bootloader (thank you Motorola), I downloaded TWRP for Chanel from the TWRP.me site. My plan was to first install TWRP, then use TWRP’s install feature for LoS 18.1 and the GAPPS.
To install TWRP recovery, I followed the instructions on the TWRP site. After starting the ADB server on my Windows 10 PC and booting the phone into the stock recovery, I used “adb boot twrp-3.5.2_10-0-channel.img” to temporarily boot into TWRP recovery. I then used ADB to push TWRP.zip onto the internal SDCARD. I used TWRP’s install feature to install "twrp-installer-3.5.2_10-0-channel.zip", presumably to both slots. To the best of my memory, everything completed correctly.
BUT . . . when I powered down the phone and attempted to boot into recovery, all I got was a black screen with a small N/A in the upper left corner instead of the familiar TWRP screens. After a while, the phone booted itself into the stock U.S. Cellular Android 10 (Hell Oh - Moe Toe). I've done several power-off/power-on cycles to no avail. I am able to get to and use the stock OS.
So, like TWRP.me suggests, I figured I’d just flash it back to stock and start over. Um, nope. I can Vol-DN/Power to the bootloader menu, but “adb devices” doesn’t see the phone, preventing me from flashing anything. USB Debugging is enabled and the phone says "USB Transfer Mode: Connected". “adb devices” sees the phone while Android 10 is running, but as soon as I boot into recovery, the phone “disappears” from ADB.
The only other thing I could think to do was to use the “Rescue” function in the Lenovo/Motorola Smart Assistant. While ADB can’t see the phone, LMSC sees it just fine and I was able to rescue/reinstall the stock OS successfully, or so LMSC said. Unfortunately, LMSC doesn’t seem to fix whatever is wrong with the recovery. Interestingly, “N/A” no longer appears after Vol-DN/Power and select Recovery Mode, the black screen now says “bad key”, followed a little while later by the Android logo with a “!” in the middle of the screen and “No command” below it.
And that’s the hole I now reside in. Despite considerable searching/reading here at XDA, I'm at a total loss for what to do next.
SOOOO, I’m hoping someone can help me:
1. Fix the N/A black screen
2. Get into a mode that ADB can see
3. Properly install TWRP
Thank you in advance,
Tenaya
Did you flash the copy-partitions.zip while in TWRP?
Maybe you could borrow some ideas from the official install instructions for LineageOS.

I had some strange intermittent USB connectivity issues with a few Moto G7 Plus devices with my main laptop, but was fine connecting on a 12 year old desktop computer. So perhaps you could check to see if adb connects on another machine. Only other idea I have is to somehow flash back to stock again with fastboot.

No, I didn't know I needed to; nothing about that is mentioned by TWRP.me.
This is unknown territory for me, but your question sparks a thought for me. I wonder if 1) The stock recovery is in the "other" slot, and 2) there is some way to boot from it. That could be a way to sidestep the ADB devices problem I'm having?
zpunout said:

At the moment, I have no way to do that. I don't think the USB connection is the culprit, ADB "sees" the phone just fine while the phone is in the stock OS, just not in recovery (EDL?.

That's my current plan, but FASTBOOT won't flash anything while ADB devices won't/can't see the phone. I'm hoping someone has a workaround of some sort for that.

Hi, first of all lets set some things straight, you are experiencing a Boot Loop, in other words a software brick. (Soft Brick) now luckily these are fairly simple to fix. Sorry to break it to you but the N/A Screen won't disappear, that used to be the Blue/Yellow Motorola Splash Screen, but since you unlocked your phone it'll only show N/A but thats okay there are tools that can help you customize this and change it later on.
Now why is it on a boot loop you may ask, well that is because there is no more operating system to load in. But worry not, try to get into your bootloader, and try to connect adb through there.

HellxDo,
Thanks for the reply.
After I used LSMC to "rescue" the phone, it stopped displaying N/A" and began showing "Bad key". Different, but not better.

Hmmm . . . The phone currently boots into the stock rom (U.S. Cellular Android 10) if I wait a while after "Bad key" displays. If there's no more OS to load in, how do it do dat?

My (limited) understanding is that the only way to "get into" my bootloader was with the Vol-DN/PWR button combination. When I do that , I get the bootloader menu, but ADB doesn't/can't see the phone - nothing is listed when I run ADB devices and fastboot won't/can't flash anything.
Is there a different/better way to get into my bootloader?
Tenaya
And the adventure continues. Here's some more information.
While continuing to research this, I was wondering if there was another way to boot the phone into EDL mode and Google found some instructions at thecustomdroid.com for using ADB to boot the phone into EDL. I booted the phone to the stock OS and used the command adb reboot edl. The phone immediately went blank, followed shortly by the "bad key" message. After a while it again booted into the stock rom.
I still cannot use fastboot because it doesn't/can't see the phone.
I have also discovered that if i use VOL-UP/PWR, the phone boots directly to "bad key", followed by the stock rom. Another dead end.
I also used LMSC to "Rescue" the phone again and learned several things:
While LMSC is running, it boots the phone into the bootloader menu and begins to flash. If I do adb devices while LMSC is flashing, the phone STILL doesn't appear in the list.
LMSC definitely flashed the stock OS - when the phone rebooted, it was back to the stock OS Android start screen as if it had never been configured.
There is still no recovery and I still can't flash anything.
LMSC is somehow able to flash without a recovery present.
Anyone have any other ideas?

If "fastboot devices" can't see your device while in bootloader mode, that could be the same issue I had relating to your USB compatibility with your computer. Try to borrow someone else's computer, install "platform-tools" to see if the "fastboot devices" command works.
If that works, next see if the command "fastboot getvar all" works. You should get many lines of info come up. If it gets stuck after a couple of lines, then the symptoms are the same as what I had. I have a bunch of really old laptops and a desktop sitting around with platform-tools just for this issue. I have heard others say that plugging the phone in via a USB hub sometimes gets fastboot to connect properly, but I haven't had success yet.
OK, some progress.
I found this:
[GUIDE][TOOL] Reboot to EDL mode from FASTBOOT! No More "Test Point Method"! [kenzo]
kenzo has graciously hacked fastboot.exe to force the phone into EDL mode. Using that, the phone booted into EDL and fastboot devices can now "see" the phone. Thank you kenzo.
BTW, kenzo's fastboot-edl isn't G7 Play specific, it was originally for the Xiaomi Redme Note 3 and seems to work for some other Android phones as well.
I'm still working on getting TWRP and LoS installed, but at least fastboot can talk to the phone.
