Hi everyone I bought RMX2202 and I rootl it. But when I switched to slot_A, the phone went blank and the screen went black. The phone responds to usb so I wanted to try to fix it using QFIL but I am not able to find the right drivers. Any advice from someone who had the same problem or at least functional qdloader drivers. Thank you.

If you're running out of options, try shoot a message to +917017426154 on WhatsApp. Fixed a brick for me with MSM tool as he has a login. Seems 99% of people don't have access to the login... Was a little sceptical at first but everything was fine and he took payment through PayPal so pretty safe. Pretty quick response times too and screenshots to prove he's legit. Found him here.

Hey, so I've looked through these forums, as well as google search, with every combination of words i could think of to address my issue, and so far nothing has worked. So im posting here, hoping y'all can help me.
My phone is the Lg optimus L9 p769 running FW v20h. I had it rooted, bootstrapped cwm recovery is installed and still accessible. Unfortunately for me, i had disabled usb debugging off. Cant remember why, but I did.
I was browsing around for build.prop tweaks, found a good list, and implemented a few. After reboot, everything was going smoothly, hell, faster and smoother than before, which i assume came from tweaking the build.prop. At that point, i chose to implement 1 more and be done. So i added the line and rebooted my phone. SOFT BRICK!!!!!
Now, as i said, ive done quite a bit of searching for a fix, including the offline fix and basic LG Support Tool restoration, but nothing is working. Offline fix says my phone is not connected. Online recovery says im already at the most recent FW available. Ive tried fastboot, but installing the u boot and x loader wont work. CMD doesnt recognize my phone when i try anything adb related (obviously, because usb debugging isnt enabled), nor does it recognize my phone as a fastboot device even with the phone displaying the mirrored logo and says fastboot v0.5 in the top right corner. Also, the bootstrap CWM wont mount my external SD, which has my build.prop backup on it.
So, basically, that what I've read into. A wall, so to speak. As a side note, my wife has the same phone with an unmodified build.prop. in fact, the only thing that i have done to hers is root it with the LGpwn app.
Now, is there anything i can do with this, other than throwing it against the pavement outside? While i think I'd get a sick satisfaction from that, it hardly solves my problem. Also, i called LG directly, but they won't help me at all without payment. Even with their CS rep saying it was their fault (because, of course, I'm not dumb enough to tell them I broke it by messing with the build.prop). However, the slight bit they did do remotely through the laptop had them going through the LG Service Tool.
Anyway, that's about it. It really is a great phone and i really would like to repair, rather than replace, it, but im stuck. Anyone got any ideas?
Hello,
I had a similar problem, offline method didnt worked for me saying that my device is not connected. Then I faund this tool on forum http://forum.xda-developers.com/showthread.php?t=2797190
Use it with described tutorial (use 3GQCT and DIAG) and you are going to unbrick your phone.
Ok, I'll give it a try when i have access to the neighbors laptop again. I'll post the results here. Fingers crossed, my phone is up and running again soon and I'll be able to post my results from my unbricked phone.
IT WORKED!!!!!
Holy hell, it worked! A week of searching and trying with no success, now my phone is up and running again! Thank you sooooooooooooo much! Can i get a solved tag?
You're welcome. I'm glad I could help
First off, I appreciate any input on this very much.
The phone is an LG K8 2017, or model US215, and this is actually the second time this has happened on a second device. Both times this has occurred, it's been during charging.
The first time, on the first device, the device was off when I took it off the charger, and would not power on until I removed and replaced the battery. Later that day, the device seemed to be lagging, so I rebooted it, and was taken to the fastboot screen. I Googled and Googled, and corresponded with LG before taking the phone back to the retailer and exchanging for another, as I'd only had it a few days.
Now, with the second device, which I've been using for several weeks, there were a couple of times that the phone was off after charging, and the battery had to be removed/replaced to start it. This time, the phone was (maybe for the third time) off when I removed it from the charger. Fearing the same issue, I removed/replaced the battery, and unfortunately, was met with the fastboot screen. LG will repair it under warranty, but I don't have a backup, and can't go weeks without a phone. I've searched high and low, and cannot seem to come up with an answer, or find a situation identical to mine.
I've tried fastboot reboot with ADB, but it requires USB debugging to be enabled on the device, which mine was not, and I'm not able to access it now. The phone was completely stock. Hard-reset does not work, as it always boots back to the fastboot screen. I am, however, still able to access this screen, and download mode. I've tried to include as much info as possible, but am eagerly awaiting responses, so I can answer any questions. Again, thank you to anyone with input!

Thank you for the response! I see the link for the firmware, but I'm not sure what guide you're referring to?
[EDIT] I think I found it. Will update after I follow the guide.
Unfortunately, LG Mobile Support Tool just tells me, "The phone is disconnected from the PC." Even in download mode.
The only time the PC seems to recognize that the device is there is when it's on the fastboot screen, however, LG Mobile Support Tool still gives me the same error.

Hello and good afternoon everyone
I am quite new to the whole rooting thing and i really hope i don't annoy anyone with my silly questions.I tried searching anything related to my problem and i tried to understand many new terms but in the end i concluded that it would be best to get a direct answer for my problem.So here i am...
A friend of mine gave me a Samsung Galaxy s4 mini(GT-9195) with the problem of bootlooping.So after Samsung KIES programs & Samsung Smart Switch Recovery Tool failed to recognise it,people told me that ODIN will do the trick.And so i downloaded the necessary firmware for my device and because the specific carrier wasn't on the list i just decided to put the (EUR) one.And it worked!ODIN reported SUCCESS.The device actually booted with the first try on the First Setup Screen.So i get it set up and i give it back to the user.But after two days it started doing the same stuff.The user ended up getting another phone but after 2-3 months he gave it to me again so i can fix it.I thought that it would be a simple problem and the phone would probably have a bad battery which couldnt give enough "juice" for the phone to actually boot.Well i found out that the phone now not only doesn't bootloop..it doesn't power on or vibrate whatsoever.It was completely dead till i connected on the PC and i actually heard a sound of connection from the Computer.So i go to devices to find a device named Qualcomm HS-USB QDLoader 9008(COM 6).So my question is.Based on what i read i probably installed a non compatible ROM and i hard bricked the device.Something like that.So could someone PLEASE help me unbrick this thing IF indeed we are talking about a hard brick right now.Really sorry if someone has already made a topic on this.But i cannot find a solution no matter how much i try.Thanks in advance!
Hello,
About a week ago, most of my phone apps (including G-apps) started to misbehave. It will write something like "chrome.android.blalbla" has stopped working; when I clicked "OK", it brings either same thing or that of another app...
I tried to clear emmc when the phone battery percent was at 2% - probably where I bricked it. It loaded for some time then went off....
I charged it for some time and the thing got stucked in a boot loop....
BTW, I haven't rooted neither have i done anything to the bootloader (I don't know if it is unlocked or locked)...I am not 100% sure I enabled USB debugging or OEM unlocking (I remember doing it for some other phones but can't really say for these)
Please, what are the options do you thing I have? I have downloaded a custom stock rom and tried to used SP flash tool to get it a new stock rom but the thing is giving an error - chksum error.
I don't know the Build number or the Fimware stock it uses...
I have gone to and fro, roaming about the internet looking for solutions but I haven't found any.
I will be soooo glad if anyone can help speedily...
Thanks for reading

Do a Factory Reset
Hello People,
I was flashing the stock rom using mi flash but the flashing timed out after 2000 seconds. I rebooted the phone to fastboot but it failed and the screen went black. [Reason For Flashing: We lost the pattern lock so i flashed the stock rom and, then twrp, just in case to avoid losing the screen lock. But then i thought of keeping it stock and when i reflashed, the timeout occurred and phone went black]
Since then i have tried many different versions of MiFlash and even MiFlash Pro, however they are not successful due to authentication issues. I took it to the service center as a last resort but they are asking for motherboard replacement which i am not comfortable spending for.
I researched as much as i could and tried QPST flashing as well but learnt that a patched firehorse file is required. And that is not available anywhere on the internet.
I am not sure what options i have now or am i doing something wrong.
Could anyone please help me in reviving my phone?
NOTE:
Bootloader - Unlocked
PC Detects It as: QDLoader 9008
Regards
i will help you. pm me asap
SORRY CAN'T HELP YOU ANYMORE. Got no more credits on my Xiaomi Pro Tool account. If you want a cheap fix then it is your only choice. Anyway try any MiFlash below 2020 to flash stock rom. Good luck.
Try mi flash tool 2.0 by Francesco tescari it may help
Thank you for your replies. I had to get it fixed from a nearby shop who claimed to have some access to GSM Forum. I am not sure which tool they used but the job was done.
I wish a patched firehorse file was available. QPST would have helped in that case.
Thanks again.
