So this is a budget phone , spent hours obsessing over rooting it, did the whole process several different times several different ways,
the funny thing is , i can't event brick this device . this runs OREO 8.1 which a chopped down version of the full OREO 8.0 , basically it's designed for budget "entry level phones" . So i'm wondering
why they would make it so unbrickable? is it possible that this device doesn't even have a bootloader? if not why is it so hard to get to it?
Can't access fastboot mode nor the bootloader
One year later and this is still an issue. Here is my situation:
I bought an OTG (on-the-go) cord that allows me to connect a USB stick to my phone in order to extend my storage capabilities, but my phone doesn't natively support OTG (it basically doesn't have the drivers for it). In order to add support for it I need to root my phone, which I am having serious trouble with.
After hours of researching, installing, uninstalling, and factory resetting I've narrowed everything down to not being able to access the bootloader to select the fastboot mode. Here are my phone details:
Device Name: LG K20 (boot screen says "LG k20 Plus" however)
Model: LM-X120WM
Android Version: 9
Build Number: PKQ1.180904.001
Software Version: X120WM11c
As far as configurations go, I have:
- Enabled Developer Support
- Enabled OEM Unlocking
- Enabled USB Debugging
- Made my computer a Trusted Device on the phone
- There are no special "adb" options or configurations within my phone (I saw one website mentioned something about "adb" some options, but I only saw this once, and my phone doesn't have it anyway).
So far I have tried:
1) Holding the Power + Volume Down button for 10 seconds, then releasing the Power button when I see the LG logo, then repress the Power button until I see the "Factory Reset" menu. All this does it give me options to Factory Reset unfortunately (which I've done).
2) Holding Power + Volume Down button for 10 seconds. This simply reboots the phone and does nothing else.
3) I've downloaded, installed (on both my phone and my computer when needed), and tried rooting using the following programs: Dr.Fone, KingoRoot, RootGenius, iRoot, SuperSU Pro, and Superuser. There were some others I tried as well, but I determined I couldn't get anywhere with them specifically because I could not access fastboot mode (one example is "Magisk Manager").
4) Using ADB tools within command prompt (the most commonly recommended method) I tried rebooting the device into fastboot mode using the command "adb fastboot bootloader". The phone simply reboots and that's it, it has not switched into fastboot mode. You can confirm if you are by using the command "fastboot devices", which my device never shows.
5) I have gone to the LG website in order to download the drivers for this phone, however, while I am able to locate my specific device on the LG website, it directs me to download the "LG Mobile Support Tool", rather than download the drivers specifically for this device. I downloaded and installed the LG Mobile Support Tool but when the tool loads it does not recognize my device and tells me I need to install the drivers, which it gives me an option to do. Naturally I start the process to install the drivers but when it gives me the list of phone models mine is not in there *and you cannot proceed without selecting a model*. So, I tried using the closest model to mine (the LMX510WM), but it still didn't work.
6) Because LG does not have a direct download of the drivers for this device specifically I have tried downloading a variety of different drivers for this device. None have resolved the issue, but at this time *I believe* I have the most recent version of the LG drivers available "LGMobileDriver_WHQL_Ver_4.5.0".
7) I've tried adding the USB drivers through any install tools that came with them, and I've tried installing them manually via "Device Manager -> Add Legacy Hardware" and choosing the driver files specifically. This has not resolved the issue.
8) Installed the "wpdmtp.inf" file found within "c:\windows\INF" as recommended for Windows 10 users on one forum or another. Did not resolve the issue.
9) Installed the full Android Studio suite hoping something I was missing would be available, I also tried using the "adb" tools they provided: no love.
10) I also tried powering off the phone, holding the Volume Down button while plugging in the USB cord. This is supposed to do *something*, the instructions says I should enter "download mode", but on my phone does nothing.
11) the XDA-Developers forum suggested installed LGBridge_Setup.exe if I was having problems with drivers, which I have. When I ran the program it wasn't able to connect to my phone.
At this time I've uninstalled almost all software and all extra drivers from my computer (I left only the "LGMobileDriver_WHQL_Ver_4.5.0" drivers), as well as having factory reset the phone.
Everything is ready for another attempt, I've just run out of ideas. Thoughts?
Hi, I have also been trying to root this phone for the last year, but failed.
Everything is exactly the same as your phone regarding Build#, model # etc except i have software version X120WM10c .
The phone always wants to update but then it fails every single time.
I am hoping to root the phone so i can debloat it, and remove the restrictions preventing me from using it the way I want.
Anyone have any advice/info please post here. I will do the same.
Anyone? No response in almost a year.

Hello,
I have probably bricked my Huawei Vision by rewriting boot image.
However, I can connect* it to PC and it sees my phone as "Huawei Handset" (same with Windows and Linux). But Windows misses its drivers (non-bricked phone worked); Linux seems to work. No OS can connect to it using default (downloaded) ADB, nor Fastboot, nor SoftwareUpdateTool.
Its PCI ID is 12d1:c002.
How could I reflash it? I would prefer the ways without disassembling the phone.
Thanks
----How to boot the phone, so you can connect it to PC:
1. turn off my phone completely (vol up + power for 10 seconds - release power for a seconds and repeat it once again)
2. prepare USB cable, so you can connect it in few seconds
3. hold vol down + power and after ~1s, connect USB cable (still hold vol down)
4. when Huawei logo appears, release both buttons - your phone is connected now

The thread called 'Problem with huawei vision' still seems to be active. You may want to try asking your question over there.
Huawei (u8850) unbricked
I just wanted to relate my experiences in de-bricking this U8850 phone.
I installed 'Apps_2.6.35.7-perf+root+CWM_recovery 5.0.2.8' (firmware.nb0) using SUT to get CWM, and then installed Danile's 4.1.2
Good as far as it goes, but i could not for the life of me reproduce his kernel (my kernels are always unreliable), so after many days of playing, i decided to take the phone back to stock to see if i could reproduce the huawei stock kernel as a base to work on.
The problem was, how do you revert to stock; the phone was no longer recognised by SUT?
So I took a stock .nbo file and extracted the content (some java extractor found with google) in the hope that I could create a CWM flashable zip of the stock firmware.. a bit of research later, and i thought i had got the gist, put boot.img and system.img into a zip with a modified script file, and voila... a bricked phone.
At this point, i had CWM, but if the phone booted, it showed a flash of blue screen (I didn't know these ran windows ), and back to huawei logo. Also I think i had to dismantle to disconnect battery to run CWM, as it's not available just on the volume-up-power restart.
So then I did more research, and came across QPST, Qualcom's tools. It seemed this should know something about the files i had extracted. I could not correlate everything in the extracted fileset with what QPST seemed to expect, but the first challenge was to get QPST and the phone talking. using various drivers, QPST would sometimes see it, sometimes not, but nothing good seemed to be coming from it. I returned to trying to get SUT to work on my brick; again, with some drivers it would connect, but a flash always resulted in Error 4000 - DEVICE_NOT_CONFIGURED.
Then I read somewhere that someone had found a driver change made SUT work, so i investigated drivers more.
What I found was that if i ran up CWM, I got two Huawei devices in XP for which I could not find drivers.
The devices showed up as VID_12D1&PID_1022&MI_00 and VID_12D1&PID_1022&MI_01.
I took the Huawei USB drivers folder, and copied the qcser.inf then changed entries under [QcomSerialPort] to match my VID/PID values.
(the two that had matching MI_ values).
On driver update, I had a serial port, plus something I'd not seen before - a USB storage device which contained the phone's partitions!!!
This certainly seemed promising... so into SUT again, same error 4000...
So the I tried QPST; and yes, it could see the phone. Scared to do anything to brick it further, I thought, ok, try some memory diagnostics.
On running the 'Memory Debug' tool, as soon as I tried to get a list, QPST said 'this phones in diagnostic mode, it must be in download mode to do memory diagnostics', but even better 'Do you want to set it into download mode now?'!!!!!
Yeah! click the button, and I see a screen I've only seen once before (and i don't know why last time), black, with a line added every few seconds... which from all my reading I know is a good sign.
OK, then I closed all QPST apps, and ran SUT.
This time, the firmware flashed no problem. Was a bit worried as boot time is long (but it was effectively 'first ever' boot for the phone).
I hope this helps someone else with this or another Qualcom based phone.
Basic lesson is:
If you see Error 4000, it may be that the phone is in diagnostic mode rather than download mode.
If you don't have drivers, or don't have the right drivers, check you VID and PID, and try putting them into the .inf file
QPST may have a simple use after all... to force a phone into download mode when SUT fails.

it's actually not difficult to remove the battery...
but i read somewhere the 'volume-up + power for five seconds' will hard restart, but re-press power immediately will then turn it off (not tested myself; the back of mine is already off at the moment.)
Anyone here interested in developing a 3.x kernel? seems other phones with msm8255 have successfully got one...
u8850 power off

now i have tried it, and no success.
However, what i have found to work - if your non-boot is actually booting the kernel, but failing to initialise the phone, then you can still use adb with it... I ran adb shell, and then used 'poweroff' to power off my phone, which then meant i could boot into CWM recovery....
i HAVE THE SAME PROBLEME? PLEASE CAN U HELP ME TO SOLVE IT BY GIVING ME DETAILS.
it is working, thank you bro

HOLY GOD! F**K ME!!! I finally did it! THANKS A LOT, BRO! YOU'RE AWESOME!!!
Hey guys,
last night I woke up, fining my phone constantly rebooting, so I tried to soft-reset it (pressed Volume Down + Power for 10 seconds). After this it booted again, but it was unable to find my SIM card or connect to my WiFi, so I decided to restore a recovery image. Note that I never installed any unofficial ROMs to this device before, everything was working fine so far, so there was no need to do it. It was running on the latest Denim-Update, that was available for the phone.
Since I was unable to recover the phone using the Windows Device Recovery Tool or the Nokia Recovery Tools, I launched up WPInternals 1.2 It showed me the correct (e.g. expected) product number and version (RM-821, 059S0K1). I then downloaded the emergency files and ffu-image from here (lumiafirmware.com/ser/RM-821/guid/059S0K1) (warranty ended about 1 year ago anyway). After rebooting into flash mode, the device started showing a Bluescreen (where only "" gets displayed), right after the Vodafone branding logo.
Since then I am unable to even connect the phone to my PC, nor do anything about it. I tried to follow this tutorial (docs.google.com/document/d/1FdTtfRcR80qnSzjHX1kvTcjMRcoWh8j5hUxw8UM_prE/edit) in order to flash the image directly using thor2. I had to remove the QHSUSB_DLOAD driver from the device manager (note that it was hidden for some reasons). I expected the "Nokia Emergency Connectivity" driver to be installed, but instead only a "NOKIA BOOTMGR" get's displayed.
Everytime I try to connect thor2 to the device, it says "THOR2_ERROR_CONNECTION_NOT_FOUND". I suspect this is a driver issue on my PC.
Do you have any suggestions how I could continue restoring the phone? Or do you think it is lost after all? (which would be sad, because I loved this device. The first one that was as reliable as I expected from it)
Thanks in advance!
I am constantly receiving
Manually invoked flash mode?
Hi, did you try this: switch on pressing the volume-up key? This should display a flash and a cog wheel. In this mode, you can use either thor2 or ImageDesigner to flash the required ffu file.
Refer to https://sysdev.microsoft.com/en-us/Hardware/oem/docs/Phone_Bring-Up/Phone_Image_Designer.
For download search for Lumia_Flash_Tools.zip. It provides 32 and 64 bit versions.

Hi everyone,
My dad's friend has a problem with his phone and dad asked me if I can help him. Right now I only know that he had "LG Security Error". However when I got the phone it didn't react on anything, so I'm unable to turn it on or charge a battery (I have also a second battery, neither of them works). When I plugged it to a PC it showed "OMAP4430". I've never had experience with LG before (only Xperia phones), but after searching I found this (2n option), which didn't work with my device, but this (1st option) worked flawlessly. I managed to get into FASTBOOT mode (phone is listed with "fastboot devices", ADB not) - OMAP FASTBOOT DEVICE. I noticed that it disconnects itself after 1-2 minutes and the proccess needs to be repeated. The phone still isn't showing anything on screen. After few hours of searching I didn't find anything, except that after doing procedure with Vol+ button entered, Windows recognized my phone (I could get only twice and the screen was still blank):
Code:
LGE Mobile Composite USB Device
LGE Mobile USB Serial Port (COM9)
LGE Mobile USB Modem
LGMobile Support Tool was doing something, but in the end it didn't detect anything, also I checked out LG Flash Tool 2014, phone information showed that it was in emergency mode. Screenshots
At this point I'm guessing that the phone is hard bricked as it couldn't go to S/W mode, download mode or show anything on screen etc. I haven't found any tut about unbricking in fastboot. Is there anything I can to at this stage?
Thank you in advance!
The com port driver is the only one needed for unbricking. Provided, that the phone is already in D/L mode, otherwise communication will first be done with the ADB driver.
I had the situation, that the phone wasn't recognized by the ADB and Fastboot drivers(with a custom rom installed), and under Win8.1 and Ten Fastboot generally doesn't work. But only the L9 is affected by this.
But if someone managed to clear the whole internal flash, with bootloader and baseband, the phone is economical junk now. Though re-flashing via JTAG is possible. While some geeks may own one of these Octopus adapters privately, even if you know such a person, he should be an LG user, too, as support for each brand or individual model has to be bought separately. Or simply invest around 100€ or $100. That is the price of a brand new phone with the L9s capabilities and a stable(!) Lollipop or Marshmallow installed.
I made the serious mistake of installing Kingroot which failed installing the first time, then it said try again, then it worked but totally took over every aspect of my phone with no apparent way to delete any of the new "features". It didn't seem to be as much about installing root as it was interested in installing some apps they force you to install which totally takes over your phone. (Side note - it is a shame that this is sold as a rooting software, it should be in reality named a virus or malware and avoided. Too bad for BLU users there doesn't seem to be any other way to attempt a root)
Then installing supersu-me created more havoc, then trying to re-install Kingroot completely locked my phone and put it in a boot loop.
Now upon first attempt, I can't seem to make SP Flash Tool or MTK Droid talk to the phone (first time trying now). I installed all the drivers that came with the forced install .exe (which installs the drivers even when no "unknown device" ever appears in device manager) but I have not yet found any "unknown device" in the Device Manager before or after installing these drivers.
When there is no data cable connected, the recovery menu must be used as the only method to power down the phone because it loops on and on with an attempted power up until the battery runs down. However after using the green on black background recovery menu (hold in VolUp and Power), and making the selection to power down, the phone finally powers down. Unfortunately, as soon as the data cable is inserted into the phone, it begins the boot loop again which makes the laptop ding-dong indicating USB driver loading/unloading over and over.
There are options on the green/black recovery menu to load from SD card and to enable ADB but I can't figure out what driver to use and which option on the green/black recovery to attempt. Of course the factory restore option did nothing and the options for ADB, Fastboot and load from SD card seem promising but all I can find for an image is a RAR file which appears as the format of someone's SP Flash Tool dump, and includes the scatter file MT6582_Android_scatter.txt plus other *.img and *.bin files.
With no way to get into my phone, I don't know how to attempt to load this image which I believe is the extraction from the SP Flash tool. I have installed CDC/ACM driver install package, Google Inc USB, Media Tek usbser from 2011 & 2007, usbvcom and Usbvcom_brom.
Any ideas? Thanks!
Just saying, whenever you root your phone you gotta make sure to have a stock firmware in case of emergencies... It's no one's fault.
hi all,
does anyone have a solution to installing a custom rom on blu studio xl (lte)? the stock rom is on Android 5.1 and its laggy as all hell.
thanks much in advance,
ak
Install mtk v com drivers.
Similar thing happened to me on a mtk phone, I have all software and drivers etc on my home pc, not here. Send me a message tomorrow to remind me and I'll Google drive them and give you a link, with instructions. It can be fixed! Don't panic! I assume you have stock firmware? If not, get that ready and downloaded ready. Also, a few different versions of SPflash tools, some don't work on some phones, even the same phones. And different USB leads also.
Hi all, I will try to be as detailed as possible.
I have a MetroPCS LG MS323 which I bought as a second phone to use when I travel as my regular phone is CDMA and I wanted a GSM phone that I could use with a sim card. While on an overseas trip I paid a cellphone place to unlock the phone so I could use other carriers' sim card, it was working fine since then. However, as I don't use the phone on a regular basis it ended up sitting and the battery lost its charge. When I tried to charge it by usb, it started bootlooping (vibrate, LG logo, repeat). After that I pulled the battery and charged it using an external charger. The phone is not rooted. I tried the factory reset key combo, but it gets stuck on the screen which says factory reset processing........ endlessly. I tried to download kdz file and flash with LG flash tool but phone cannot get into download mode. When I press vol key and plug usb cable, it says LOADING.......... press volum up key until download mode starts But it gets stuck there and download mode never starts.
I downloaded adb and fastboot to a Windows 7 laptop, and LG drivers, but when I connect phone and open a terminal adb devices shows no phone connected.
I also downloaded Laf.img for this phone and Laf recovery tool for Windows but again I cannot seem to get computer to see the phone. If I try to use the tool it says "waiting for device"
One difficulty is to trying to plug phone to computer the right way.
Most of the threads say to have phone in battery charge mode with usb debugging enabled, but I can't select any settings if the phone is bricked.
If I just plug the phone to usb when it is turned off it shows a picture of battery but no sign of charging, and computer doesn't detect phone.
If I plug phone to usb first, then hold vol and power key the LG logo will go black and it vibrates, in that case sometimes the Windows laptop will see 2 folders, verinfo and image.
When I plug usb cable to Linux computer and phone is off, same thing just picture of battery but terminal only shows sda1 sda2 sda3 etc no sdb no sdc just like not detected.
If I hold vol down then plug usb it vibrates and stuck on LG logo.
I have also tried to plug usb, then press vol down and power until phone vibrates, then try to let go buttons before LG logo shows up. but it doesn't mount.
If I hold vol up and power, then plug usb. it vibrates and goes to LG logo.
Last night somehow I got it to mount on the linux computer but the file manager was going crazy opening multiple windows and a list of folders would show up for a second, disappear and reappear as if the system was trying to read the folders but having difficulty. Today I am not able to get it to mount.
I have downloaded a linux livecd with adb and fastboot, I haven't tried it yet because I am not sure the path to flash an img file from a different directory on the hard drive on the windows laptop.
I have downloaded aboot.img but don't know how I can flash it if I can't see the phone on any computers.
I have spent days searching for solutions but have not seen the exact same problem, other threads suggest things but often the symptoms are slightly different or with a different phone. So, first of all I need to know what kind of brick I have, because other solutions I have seen posted for completely black screen, or phone detected as qhsusb qualcomm etc. which seems like a different problem.
So the 2 main things are 1, to know which kind of brick because many of the solutions I see posted seem like a different problem.
second, what is the best way to plug to computer so I can see the phone?
I burned a live CD of FWUL and ran adb from linux, still says adb devices nothing shows up. usb cable is plugged in and phone is turned off. Am I doing this wrong? I held down power and vol down until phone vibrates and LG logo appears. adb devices - "list of devices attached" still has nothing showing.. I don't know why even in Linux I can't see any device attached. Also I tried with pressing vol up and power until phone vibrates.
ls /dev/sd* only shows sda sda1 sda2 etc
I have also looked at past threads about unlocking the L70 bootloader, but the bootloader.zip no longer links and the phone does not have busybox installed.
I tried to see it Windows Device Manager but it does not show up anywhere.
This probably won't help, but, when you're at this point, you'll try about anything.
Did you fully install the LG drivers on your PC? Obvious seeming question. I was doing an old Droid Bionic a couple months ago and didnt' switch the USB modes (charging, media, file transfer, whatever it had) to each mode before modding .
As a result, I bricked that Droid bad. It took me almost a week and a half to restore it. I'm not sure if LG drivers work the same way, though I've worked on plenty of them. I think I have an LG Leon still in the scrap heap as a result of trying to replace a cracked digitizer that was bonded to the LCD. If anyone needs parts for one, I've got em, cheap I think that's an MS345 if I recall.

Thanks, yes I had installed latest LG drivers LGMobileDriver WHQL Ver 4.2.0 before trying to flash .kdz file.
A tiny bit of progress to report, after getting a perfect timing to release the power and vol down keys I was finally able to connect to Windows machine. while waiting for drivers to install it was detected as QHSUSB_BULK in device manager, after drivers loaded now it is listed as LGE AndroidNet USB Serial {port (COM4). However when I run adb I still cannot see an attached device. I will look at solutions for the specific type of brick problem which has now been identified.

What I meant was after initially installing the drivers did you switch the USB mode on your LG to all possible settings? Some drivers (like Moto) install more functions only when first called. you'll know if you switch from say charging to MTP or RNDIS you'll see driver install reopen.
also when you first ran ADB and plugged in the phone you probably should have seen more drivers install.
Forgive me if I seem to insult your intelligence. I'm an IT pro w 30 yrs in tech and I didn't know about the multi driver USB functions.
Tom Sgt aka Rootjunky has a good video on this that i initially didn't watch figuring I'd been installing drivers forever. 5 more minutes of watching it would have saved near 40 hrs of work and research

thanks, I found his video for the G2 and no, I have never seen that with the drivers before! good to know. You can't insult my intelligence because most of this is over my head and I'm just trying to follow stuff I found with Google on XDA......
I downloaded and installed the Qualcomm drivers to try and identify if I have the 9006 or 9008 variety brick. However now when I plug in the phone Windows waits to install drivers, then says successful, when I look in device manager now I can't find the phone. But I did notice on the taskbar now there appears an icon named "intel graphics media accelerator driver for mobile" perhaps that is the driver Windows assigned to it? Device manager does have Intel Graphics Media Accelerator under display adapters. The other weird thing is that now it shows the battery as charging, which it never did the other times I plugged it into usb.

have you seen this thread.
https://forum.xda-developers.com/showthread.php?t=2773123
it has the firmware for your model links to drivers and the LG flash tool, (which is warned against newbies (what the hey, it can't get much worse, we were all newbies once, )
Can you boot into fastboot? if so, you could flash the firmware with that.

Hi, yes although those links no longer work I have found the drivers and flashtool elsewhere. If I try to run flashtool it cannot see the phone. I cannot get into fastboot, and download mode won't load. I cannot see the phone on any Linux machine. The most I can do it see the phone as E: Qualcomm MMC storage USB device in Device Manager, but no other details. Explorer can see 2 folders, image and verinfo. Is there anything I can do with these folders in Windows? adb and fastboot run from terminal still do not list any attached device. Windows did a search for drivers for QHSUSB_BULK, although in device manager it still says LGE AndroidNet USB Serial Port (COM5).
What I really want to do at this point is push aboot.img to the phone, but for some reason I can't access the phone with Linux or adb. maybe because it did not have usb debugging enabled before it bricked. So many of the threads I have seen require a working phone to implement the steps, is there any way to enable usb debugging when the phone doesn't work?

Of course, I had forgotten about that. In order to use fastboot, most flashing tools, you HAVE to have USB debugging on.
There are occasional ways around this, though they are few. I do seem to recall oding it on that LG Leon. OR it may have been a Moto e or G, let me look back at previous threads i've asked for help in.
(Hmm, perhaps taking notes, or just leaving a webcam running while I'm doing a new device might be valuable in the future, I think with remarkable hindsight.) :cyclops:

And no, you can't do anything to Android files in Windows, except see them. they are generally a different file system
One of the difficulties is just plugging it to a PC. 9 out of 10 times it is not recognized and nothing happens. So far the only way that seems to occasionally work is to plug the usb cable to the Windows 7 laptop, hold vol down and power, release both as soon as it vibrates. Most of the time I can't get it timed exactly right, but if I'm lucky sometimes Windows will detect the usb connection by following these steps. If I try on a Linux machine nothing happens, phone stays invisible. The most I've gotten with Linux is to charge the battery, but will not mount.
It is just a stock phone, not rooted, no busybox, no developer options enabled.
