[Q] Problem with LG P768 - LG Optimus L9 P760, P765, P768, P769

Hello, I'm aware that many other users had the exactly same problem, unfortunately.
Five days ago, I left my phone charging plugged in my computer as I do every day, next day when I woke up I dressed me and unplugged it from my computer and put it in my jean, two minutes after I got it in my hand and I saw that it was dead, tried with no success to power on it.
I plugged it to PC again and I could power on, so I've unplugged it and it died, did the same again and I could stay with it alive for 1 hour and half, after that only when plugged to power on, when going out of work Ive unplugged it and it died, after that no more power on
I Read about everything in xda and google, the result of using fastboot was "FAILED (remote: partition does not exist)"
Tried to flash the boot / recovery / x-loader from the KDZ using the KDZ extractor to IMG and the result was the same as mentioned above.
As I read I could understood, no partition is avaiable/present.
My warranty died when I rooted it, and also expired 6 days before the problem appear (...), anyone can Help?
I'm think, if is possible to make the SD card bootable?

[Q] Lenovo phone bricked itself?

Hi,
I've got Lenovo s650, rooted with a custom rom (MIUI). All was perfect for weeks but few days ago it started randomly going off. Then I noticed that sometimes when I listen to music it crashes (making the music freeze and repeat same note for like 10secs) and shuts down. I thought it could be related to some apps but since I was very busy I didn't do anything about it.
Now today I noticed that my phone suddenly lost network coverage (in area where I always use it). I tried airplane mode on/off but didn't help, so I powered off and thought I will do hard reset when I get back home. However since then the phone is completely dead. Can't get into recovery, if I plug into USB nothing happens, if I take out the battery the red light turns and it goes to "META" mode for few secs (as it's intended to) but I can't download anything into it as I get some DRAM error in Upgrade /flash/ tool.
Funny thing that somehow I was trying all the combinations Volume up/down/both + power and at some point I randomly managed to turn it on so I was gonna make a backup of my stuff but it froze and shut down again. Now nothing works......
Any ideas what happened? :/
Some additional info:
I've got TWRP recovery (however I am unable to re-download it again via flashtool because of DRAM error).
I tried getting into adb but I am not sure if it's possible when the phone is off (tried volume button combinations with battery in and out but nothing).
Also when my phone is with battery and I put it into USB, pc recognizes it as "MTK USB Port", but it keeps disconnecting and reconnecting every 5 seconds. Tried to replace it with adb USB driver but didn't work.
Not having a phone I'll probably give a "Format all" option a shot in flash tool... either gonna brick it forever or fix it..
Edit1: Can't even format due to DRAM error....... :/
Edit2: This is so bizarre... I managed to connect my phone a couple of times in Mediatek preloader mode so the flash tool started flashing the rom, but stopped in a few mins unable to format something because it's protected.
I also managed to turn on the phone a couple of times and tried connecting via adb, but once I grant root permissions, adb shell on my pc cannot find device anymore.
It seems like either a hardware or kernel problem but I know nothing about either of them..
Edit3: I don't know how but I fixed it. Phone seems to be fine for now
Edit4: After 1 hour of working the phone died in exactly the same way.... And so this 6-week old phone will be going to rubbish bin. End of my blog.

[Q] LG L9 P768 bricked data recovery

Hi all
My first post here and I'm new to troubleshooting at this level. I've been reading around but I don't think I found a thread specific to my problem. I charged my LG L9 P768 overnight as I always do and in the morning I unplugged it and wanted to restart it. However, once it shut down it never started again. I've tried all the button combinations to no avail. There are no lights or any vibration or anything when I plug it into the wall to charge it. It was so weird. I suppose that classifies it as hard bricked? However, the battery still charges (I tested by checking the battery % on another LG L9). When I plug it into the computer, device manager recognizes a device and tries to install the OMAP4430 drivers but fails because my phone keeps connecting and disconnecting every few seconds. I have tried manually installing those drivers after reading some fastboot guide somewhere. The driver install worked but I'm not sure how to proceed from there.
The phone has never been rooted and I can't remember which version of android it's running., but it's not later than 4.1.2. Is there any way to recover the data? I have some very valuable pictures on it...sigh
Thank you

Bricked Xperia Z3v with locked bootloader, can't enter recovery or flash mode

Hi guys. So I have been going through xda and Google for hours and hours trying solutions, to no avail. I almost never post on forums for help because I can usually find the solution. Not this time. This is my last resort next to throwing my phone out a window or praying for death's sweet release.
The facts: I have a rooted Xperia Z3v. I tried to upgrade TWRP in order to follow some directions on upgrading to Nougat. I flashed TWRP from 2.8.X.X to 3.X.X.X. I rebooted and it never made it to the Sony logo. Now, if I plug the phone in to either a wall socket or PC it vibrates, endlessly at three second intervals, each time with red LED. If I try to enter flash mode, then its the same but with a brief green led after the red. I can enter fastboot (the only way to stop it vibrating while plugged in) and my PC sees it, including Flashtool, but since my bootloader is locked permanently, I can't really do much with it.
When plugged into the wall-charger, I noticed that the charger's LED changes from "Active" to "Inactive" with every vibration. I'm pretty sure I'm in a reboot loop. The screen is totally dead and there's no logo, but every three seconds it kills it self and comes back.
I have tried everything I could think of.
What I have:
I have the stock firmware ready to go
I have TWRP backups on SD card and PC
I have Flashtool
I think my drivers are good, but not 100% sure
I can fastboot
I'm at my wit's end and losing hope.
Please, I'm open to any suggestions at all.

SM-T350 bricked and wont even turn on

Hi.
I recently tried (stupidly) to install CWM on SM-T350. It failed and bricked. I then was worried about the boot screen burning onto the display, so I opened it up and unplugged the cable next to the battery one. I plugged it back in, and tried to turn it on, but nothing happened.
Please help......

My Xiaomi Mi9 no longer starts in Fastboot mode. (No OS Installed)

Good morning to alle? for now,
So now to my problem.
I had a lot of time yesterday and wanted to root my new Mi9 and install TWRP to adjust my device a bit. It all worked fine until the phone started into a boot loop and stopped working. Of course I booted into TWRP and reset the phone...without success. Then I deleted everything that was to delete and tried via. Fastboot Miui 11.0.5, which didn't really work. With Miui 10 it worked then and I could set up the device again. Then I thought to myself that it might now work to install Miui 11 via Fastboot (Of course it didn't). That was at 0:30 at night, so I was tired and went to bed. I switched off the mobile phone, the Fastboot mode, so that the symbol doesn't burn into the screen. This morning, about 20 minutes ago I wanted to start a new attempt, so I pressed the power button...and nothing! I also tried to press for about 20 seconds...but without success. I also charged the device for a short time, I noticed that the LED does not light up during charging. But I can't imagine that the device is empty, because yesterday it had 100% battery. Now it is hanging on the charger. I also tried to start the phone via Minimal ADB and Fastboot, didn't work, because no device was detected on the PC.
I hope that is still somehow to save, I was perhaps a little overconfident there. But I think I am in good hands here and a solution will be found.
