Please help - POCO M3 Questions & Answers

So my cousin has Poco M3, and it is affected by the deadboot problem. The phone did an update and she restarted it. Well since its affected by deadboot, it didnt really boot up. And now, when we open it (we were able to open it up by following some youtube videos), its saying "System has been destroyed". I tried connecting it through the usb cable to my pc but its not detected (since its not really booted up). Its showing as Quectel. Please help us fix this. We cannot afford to go to a tech. Please help

I assume that you didn't unlock the bootloader, and you simply take the update and then the update failed to be installed.
Not sure what you mean with: "when we open it (we were able to open it up by following some youtube videos"
Assuming that my guess is right, then the first you could try is booting to the stock recovery manually, from the device power off, pressing volume up + PWR buttons, on the recovery screen, tap on wipe data, this will completely erase your data and settings. Try to reboot.
If this doesn't solve it then download the latest firmware for the device to be flashed through recovery (zip format) https://xiaomifirmwareupdater.com/archive/miui/citrus/ transfer it to your SD card and apply the update from it, unfortunately not all the recovery versions offer a menu to do that, check first if in yours, this feature is included.

[q] problems with lg gt540

hi guys.. could you help me with my problem.!
I have an LG GT540 android 1.6 firmware version(stock)
So here are my problems:
1. I tried to upgrade it from 1.6 to 2.1 using this tutorial http://forum.xda-developers.com/show...27&postcount=3 thanks to lavero.burgos for posting it, I was successful at first part, but I cant follow the next because my device wont go to fast boot,, I tried putting it off, then camera+poweron but it doesnt do anything. It doesn't light, no lg logo appears, just nothing although the computer can read the drive when I connect it through usb. So I cannot flash it to 2.3,2.3 because it just wont go to fastboot.
2. When I turn it on normally, It takes long before it response like after 30sec to light, but just light, no lg logo appears although it wasnt bricked because I can use it normally after just waiting to on.(annoying)
3. Since I upgraded it to 2.1, I lost all 3rd party application and the internal apps were the only left, so I copied all my saved apps (.apk) to my sd card but the problem is there is no saved app on my phone to read and install those apps from my sd card.(irritating)
4. My device wont read my sim card, when I start it it says "sim card unprovisioned" so basically I cant connect to mobile networks here in the philippines(im using globe telecom). I feel that Im stucked in the middle of nowhere since I cannot contact and txt all my family and friends.
5. I cant connect to wifi,, when my device detects wi-fi, I try to connect to it but from the log it only try to connect but doesn't obtain the ip address. Even when the wi-fi signal is strong, it does the same thing.
So please help me guys,,I want to hear from my fellow xda-developers badly,,,
PS. also those who have problems with their LG GT540 pls feel free to post and share it with us here... thank you all guys in advance....

C:\Desktop\adb rebootloader
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: protocol fault <no status>
C:\Desktop\fastboot flash recovery recovery.img
< waiting for device >
Did I miss something???

yeah I installed the drivers...
hmmm maybe there are no fastboot drivers(main suspect....) there are a few ways to get it but for mine i just plug my phone in to my pc (windows 7 64bit) it just recognize it and tries to get the "google fastboot interface" drivers from windows update...
Try Volume Up+Search Key+Power to go into Fast boot Mode, There's different keys to activate Fastboot Mode (There is different versions of Fastboot)

Your phone is/was bricked
Hey, I'm sorry to bing back such an old thread, but I just wanted to say this for posterity: your phone has/had a soft-brick. This means: you can't see Android nor LG boot logos, can't enter Recovery and (maybe) can't access Fastboot, but I'm not too sure on that last one. Besides that, the phone works "okay", but you should try to fix it.
Basically this soft-brick is almost always caught when upgrading from 1.6 to 2.1, so everyone should have it, including me. It took me a whole year to realize how to friggin' fix it lol, but here goes what I did:
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
------------------------------------------------------------------------------------------
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

Removing USB connection while flashing

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!
If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

Thank you for your reply. I found this on the sticky threads: "[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2".
I installed ubuntu and followed the instructions. when I type the following: "gdisk -l /dev/sde" I receive an error message:
"GPT fdisk (gdisk) version 0.5.1
NOTE: Write test failed with error number 13. It will be impossible to save
changes to this disk's partition table!
Problem opening /dev/sde for reading! Error is 13
You must run this program as root or use sudo!"
My device is not rooted, is this the problem?
Please help me!!
Thanks
@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:
Thank you all for your support, this is an excellent forum!:good::good:

Nope it isn't the end try to install the recovery again or try to push the custom twrp recovery again to the right partition! Dont give up that fast when i hear your things then its still fixable! you already got the factory reset processing so try to Push the Recovery again and search for an guide about recovery maybe Then you would probably get your device fixed.
Just read my things about simplicity so think easy and you can fix it. AND STAY POSITIVE You will repair your phone today :good:

Do you have any other suggestions?
Can someone please help me. How can I get to the LG device- Is there another software I can use to flash files into this device?

Sorry for late reaction but i needed to think of something. Did you tryed to use another cable? Did you tryed to do it on another pc? Did you tryed to maybe install LG PC suite and see if it gets recognized? If you have the PC Suite you may need to turn it off in the LG flashtool idk. Can you tell us more like which windows you have?

Hi,
I tried all you suggested, however my devide is not recognized. I tried to use the LG PC Suite and to flash by IMEI, however it is still saying that no device was connected.. I checked windows device manager, and nothing changed there.
There is any chnage I can see my connected device? use some tool or another software?
Thank you again for your patience and help!

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.
Issue was solved- device was fixed under warranty
Hi,
I just want to update you all that my device was fixed under warranty! (motherboard replacement)
Thank you all for help and great support, this is a great forum with great community :good::good:
Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.

Please help to unnbrick ZTE Blade AF3 (T221)

My ZTE Blade AF3 (T221) can't boot into fastboot nor normal mode (so I could use adb). I can only use recovery mode. I tried to flash the stock firmware through apply update option, but the latest available firmware online is 1.0.4 and the recovery is on 1.0.5 (DIS_RU_QB18D_P731A20V1.0.5). That wouldn't be a problem if the update-script didn't check for the version of the current firmware and abort the installation because it's newer. I tried to delete the checking code from the script, but then the file verification check fails. I didn't find an option to turn that check off and I can't flash a custom recovery due to the lack of fastboot mode.
There is also another mode to which it can go into if I just let it boot without pressing any buttons. The ZTE logo appears, then disappears and the white screen remains. In Device Manager it's identified as "Gadget Serial". I don't know if I could use it somehow.
Is there anything I could do to flash the stock ROM or another recovery to the device?
Thanks for help!
Edit: If someone knows a method to boot into fastboot other than holding down the volume - key and plugging in the USB cable the advice is more than welcome, I just think I tried every kind of button combinations (although I wouldn't have guessed myself the process to go into recovery mode, so there's always the chance).
You already solved it? Maybe i can help you!

Nope, I abandoned it. I even wrote to ZTE support, but they said I should wait for the newer firmware to be uploaded to the site (which I kept checking for a while, but nothing happened, so I eventually stopped). I haven't used that phone since, it now lives in the bottom of a drawer somewhere .
If you have any tips, I can try to make it work, but it's not that important anymore, so don't bother if it's too much work.

Probable brickage of TN7

Hi folks,
So, after little usage due to instability caused by the Lollipop upgrade I hadn't used the TN7 in a while. Yesterday I thought I'd have a go at reconditioning it.
Background: The bootloader has been unlocked, recovery was TWRP, I'd flashed and reflashed stock ROMs of KitKat and Lollipop several times previously. The main problem in Lollipop was that whilst the SD card files were showing up fine in FS Explorer, I couldn't see any of my files or folders when looking at local storage. Also, Google Play Services refused to update (or install using an APK).
Yesterday I grabbed the factory ROM from the nVidia site to do a full factory install and reset. I followed the instructions, flashing the recovery, boot, system, userdata, staging blob and dtb in that order. I then rebooted and...nothing. No power (or so it appears), no boot screen, no ability to get back into the bootloader, nada, zilch. When I read back through the flash commands I noticed that the final part of flashing the system image failed, which could well be the cause - I should have paid more attention.
I've searched all over and tried multiple options to get the TN7 to boot or show some signs of life. I don't even get an LED showing when plugged into a wall socket to charge.
The device doesn't show in fastboot or adb on the Mac. I did however get a small sign of life from Windows. If I hold down the power button for around 10 secs and let go, I can hear the Windows chime of a device connecting, immediately followed by a disconnect sound, the Device Manager updates but shows nothing new.
So my question is: have I completely screwed the pooch, or is there something that can be done to resurrect it?
Cheers for reading,
Gray

It can be fixed via apx mode.
Download drivers and switch to apx mode.
Follow instructions http://mobileviandroid.blogspot.in/2015/07/nvidia-tegra-note-7-apx-images.html?m=1
Remember to change your device serial number as mentioned in instructions.
I also faced the same problem as you are facing now. It fixed. If you need any help further just post. God bless. Hope it helps

Stuck in rescue mode after tried flashing stock firmware

Good evening! I hope you can help me.
I flashed LineageOS 14.1, but I wanted to go back to EMUI. I made all the wipes and tried to flash different stock firmwares through a forced update (volume buttons + power button), but it never worked. At that point, I read about a guy in this forum who suggested to create a flashable zip with Huawei Update Extractor: I followed the suggestion and tried to flash it with TWRP. No error was given, but when I tried to restart, TWRP told me I had no OS installed. I thought it was strange, so I tried to restart anyway. That's when I got in rescue mode. I can't get into the recovery and I can't use fastboot. What rescue mode shows me is:
RESCUE MODE
Attention!
Please update system again
Update User Guide:
*link*
*android avatar*
Error!
Func NO: 10 (boot image)
Error NO: 2 (load failed!)
Pressing the three buttons, I'm able to force an update. The problem is I can't find a firmware that doesn't get rejected. With Lollipop firmwares, it starts to install, but it fails at 12%. With Marshmallow ones, the installation process doesn't even start.
What can I do to make it work again? I'm very sad because this phone was gifted to me a couple of days ago and I already messed it up. I don't even know how to turn it off.
What can I do to get in fastboot mode? At that point, what should I do to flash the stock firmware? Or maybe do I need to find the first stock firmware ever installed into this phone to make the forced update work?
Please, I need help. Thank you in advance!
P.S. The phone's model is ALE-L21. I live in Italy, so I assume it's a European version.
Did you managed to fix this?

Not yet, but I'm working on it. I found out that the device is recognized by my PC if I follow these steps:
1. Connect the phone to the PC and wait for it to go in rescue mode;
2. Wait until the notification LED stops to blink;
3. Disconnect the USB cable;
4. Press volume - and power button;
5. Reconnect the cable.
At that point, the screen turns black and the phone is recognized as "㄰㌲㔴㜶㤸". I installed the drivers and now it's recognized as "HUAWEI USB COM 1.0". I should be able to reflash the partitions and make my phone work again, but I'm still trying to understand how to do it correctly.
Any help is appreciated!

fastboot detects your device when you plug it into your computer?
I mean, if you run "fastboot devices" it shows your phone?
I've had this same problem but with an P8 Lite 2017, after flashing some ROM that supposedly was the stock one and trying to flash recovery I ended up with my phone bootlooping into rescue mode, I was able to "bypass" this thing rebooting my phone like crazy, seriously like after 20 reboot it finally booted into the damn ROM and I never touched the phone again. Sometimes when the phone ran out of battery and tried to power it on the phone booted into rescue mode and again after some reboots it booted to Android but now I want to install a custom ROM or at the very least root this damn phone so that's why I'm asking you if you have solved this, if you do then probably if I follow the same steps I would be able to fix that screen, hopefully.
If you are able to flash something start with flashing all recoveries your update.app has, maybe that's the problem (at least in my phone it is).

No, it doesn't show anything if I write that command...
I guess mine won't ever boot into the rom because it seems like there's no system installed. I made some researches and found out there are some softwares that let you reflash the partitions IF the phone is recognized as "HUAWEI USB COM 1.0". I'm still trying to figure out how to do it correctly though. I feel like if I do something wrong, then my phone won't probably turn on again.
In your case, you should be able to flash a custom rom without any issue. You just have to be very careful and inform you as much as you can: I don't want your phone to end up like mine?. Anyway, it seems pretty hard to go back to the stock rom, so think about it before you flash a custom rom. Also, make a Nandroid Backup is very important.
