[Completed] [Q] Black Screen of Death

Hi everyone ! I am new to forum, so please forgive me if I post into the wrong category .
I have a very big problem with my phone (LG L3 Optimus E400) . I have installed a lot of custom roms on it and yesterday I realized that the current rom I was using doesn't receive text messages so I decided to try antoher one and I had the "great" idea to Flash v20 Baseband for flashing SlimBeane610 rom. That was very silly. After I flashed the rom, I rebooted my phone and nothing happened, screen is black all the time. When I press the power button the phone vibrates and the back and menu buttons lights up for 1 second like normal log on, then boom, all goes black again and if I don't remove the battery and I press the power button or any combination (like Reset, Emergency mode) doesn't work. I googled everything, I found something on this forum but not very useful. I tried wit adb but my phone isn't on so it can't be recognized. I tried wit KDZ Updater (until the phone was recognized) but I get a error like WParam: 100 and LParam: 500. When I connect it with USB sounds are playing like normal and Mobogenie wants to connect with it but I can't enable USB Debugging so it's pissing me off . If I can enable USB Debuggins from PC somehow, maybe I can connect phone with Mobogenie and make a restore , a backup or flash another rom, it would be easy If I can go into recovery or emergency mode but I can't . If it would exist a software that can erase everything on the phone when the it's turned off ... .I tried with LG TOOLS, LG PC SUITE IV, LG FLASH TOOLS, Android MULTI TOOLS and nothing(i have the latest drivers installed). Can I make something to it using the external_sd (like put a flash into it, connect it through PC via USB cable and try to flash a rom from command prompt but I don't know the paths). This is a very hard problem, I have a bricked L3 and I don't know hot to unbrick, I think isn't only a soft problem, maybe I should do something with its hardware ? If anyone could help I would really appreciate .
Thanks in advance !
PS : I won't be able to follow this conversation until the next week because I am going to "Primitive Age" right now...oh God, I'm only good to smash things . :crying:

The most important thing is, can you see the LG logo that shows up in normal boot? If you don't, it'd be either a screen problem or a hard brick. Nobody except LG can fix these problems, and you would have to pay LG some money to fix the phone. But if you DO see the LG logo and your phone stops, you can try the below options.
It just may be bricked, and you could try getting into recovery and flash an alternative ROM. But if that doesn't work, tryLG mobile support tools to get it back to its stock firmware. Good Luck!

No, I can't see the LG logo . If I could saw the LG screen was very easy to fix it. I think the phone it's really dead and I also think that even an authorized service can't fix it . Do you know an approximately price for fixing this issue ? Thanks .

My Mstar S700 won't Start

Hi ! I have a Mstar S700 and a few days ago I did a Rom upgrade with SP_MDT_exe_v3.1504-A2015.03.18-v06-customer,

split second appears the logo or the batter charge but that's it!
Please if someone can help me, i tried 3 days with no result and i m hopeless !

[Completed] Please Help, secure booting error lg optimus f3 LG MS659

I keep getting a message on the LG startup screen, that says,
"secure booting error
cause: boot certification verify"
My phone was rooted using king root almost 6 months ago, and I had no problems with it. Until around a month ago, it started getting real slow and apps would randomly stop. So I decided to format the phone. There weren't many problems after that. but after a while it started getting slow again, but slower than the first time. One day almost every app closed and "LG Home" would close, it would give me some kind of error. I turned it off and tried turning it back on, but that's when I got that error. At first i thought my phone was bricked, i still sort of do, so I tried several methods. I can only turn the phone on in download mode, and my computer recognizes it as an android device.
At first I had some problems because i couldn't find my right .KDZ file, I used KDZ Update and I tried using LGFlash tool, but i can't find any of the files (.bin . dll) I need. I've also tried using the 2014 version of the LGFlash and used the LG Mobile Support tool, and nothing! They all take around 4 to 5 hours to finish!!! It never says there's an error or anything, none of them do! They always finish successfully, but the same thing keeps happening. Every time the phone reboots, it gets stuck on the LG logo and i get the secure booting Error!! What else can i try? Any suggestions? Am i missing something? All drivers are installed correctly and I've tried on windows 7, 8 and 10! Is there anybody who can help me? What do you think the problem could be? What causes the "secure booting Error!"?? :crying: :fingers-crossed:

[Completed] Doogee X5 Pro Bricked

Ok, i have a doogee x5 pro phone and i tried to root it by flashing twrp recovery using sp flash tools. While flashing i got the error "PMT Changed for the rom it must be download". So i did a small research on internet and i found out that i needed to format everything except bootloader. This succeded. So after that i tried to install the firmware with this succeding to. Unfortunately the time i tried to turn phone on it was dead. SP Flash Tools wont detect it anymore. Please help me cause the phone is not mine and its brand new! I can rate my self as moderate android user. :crying:

i think i have a bigger problem... I downloaded a stock rom for doogee max pro(cause i just realised it wasnt just pro it was max pro) and it didnt seem to be recognised again. Any help would be appreciated. I constantly keep trying to raise it from the deads. Thanks!

On mtk devices a preloader is independently installed, it should be almost impossible to destroy, I owned a x5 pro and had best success to flash it with sp flash by taking out the battery, press flash button and plug it in...
The second huge issue I see is when you used the specific flash tool format option you very, very likely killed the nvram partition which contained the imei, so you'll have to fix this too by generating a new one and using mtk engineer mode which is well described and to find on Google..
But let's go step by step. Check without battery, or if it's a non replaceable you'll need find the reset button..

i have tried before without battery and i tried just now but nothing. Its very weird it was detected before and now no in same and another machine. I am pretty confused and stressed. Hope i didnt do any physical damage.. :crying:. THANKS!

starting to get pretty stressed omg! and is there a difference between MT6737M and MT6737?

i came to the point im starting to lose my mind... tried everything i could, i have 5 days left to repair this phone and i dont wanna pay 85 euros for this. SP Flash Tools wont detect the phone. Tried almost 5 different scatter files,2 different PCs and different mtk drivers. Im losing my mind already

UPDATE: I almost fixed it! I had flashed wrong preloader so phone wasn't recognized by SP Flash Tool. I fixed preloaded with a little trick from here: link. After that i flashed stock rom downloaded from doogee.cc but phone will not boot resulting in a total black screen. When i hot Power + Vol Up it takes me to another screen:
Select Boot Mode:
Recovery
Bootloader
Normal
Doesn't matter which boot mode i choose i just get a total black screen which means i get nothing. Idk what is happening! Any further help would be appreciated! I constantly try to bring it back working with little success and small improvements.

Last UPDATE: FIXED my phone had no juice left inside so couldnt complete boot proccess. Now its all good running Btw someone must pin this META trick link i send on my previous post cause im sure more people out there have preloader issues!!! Thank you everyone!!
