[Q] System.sin error!! Help me please

Few days ago my device got bricked, when I press the power button it gives me a red light (2 times) when I plug it in to a wall charger, light keeps constant... I've charged the device for 12 + hours and then tried to reflash stock roms 4.1 and 4.3 (CE/AU/GE) using latest flash tool. It gives me an error at the end of processing System.sin. I changed data cables, try different pcs but nothing did work. Then I tried to update the phone using PC Companion but it didn't worked. Then someone told me to flash the files without System.sin using flashtool and then extract System.sin using 7zip and flash it using Fastboot software. (command line software) when I try to flash from there it says FAILED : File size is too large. Please help me out. I'm really pissed off right now because there are no sony care centers in our country. Someone please help me out. I really appreciate your help. Thanks loads :crying:
PS : I can unlock/relock bootloader.

If you wish this will take some quite amount of time. And above all theoretically constructed. But I do wish it could help you. Now lets get dirty!
REQUIREMENTS:
DoomLord's Advanced Stock Kernel
An unlocked bootloader!
Flashtool
A .ftf of your desired firmware
I am assuming your device is now capable of turning on (battery juice present).
Overview
You will create a flashable zip of the stock ROM with Flashtool. Afterwards flash it through recovery
Procedures
Whilst having a stock ftf in hand, follow MrSteve's handy guide on how to create a stock ROM .zip (Post doesn't tell you how to extract an ftf! Its easy, rename the file extension to .zip and extract the contents (.sins (lol)) to an another folder. If otherwise your zip manager support ftf extraction, then proceed on your own method)
Flash DoomLord's kernel via fastboot in flashtool
Connect your phone in fastboot mode (hold down vol up while device is powered off then connect to your computer. you can release vol button once phone is detected)
Flash DoomLord's advanced kernel by selecting the Lightning icon in the toolbar, select Fastboot mode, then select "Select Kernel to Flash". Navigate to and choose your downloaded DoomLord's kernel
Unplug your phone upon completion.
Turn the phone on, while on LED light, press volume up key repeatedly until your phone gets into recovery.
Wipe your phone clean! Please wipe /system, /data, /cache and dalvik. You are encouraged to also factory reset through the recovery.
Flash your self-made stock zip.
Reboot and lots of prays
Thank you so much, I followed your instructions and managed to flash it... Then I got offline charging error. Then I relocked my bootloader and and flashed stock rom 4.3. It flashed... Now phone works but offline charging is not working. Any solution :crying:

Have you tried specifically flashed stock ROM through flashtool after successfully flashed the zip you created earlier? In fact this problem shouldn't happen. And from what I remember, this might have to do with Kernel.
Please flash again the stock ftf. If is still fails, please get me to know it. You can untick DATA APP etc under the WIPE section in Flashtool when you are selecting a firmware. This will preserve your data and everything.

Secure boot error / Critical error demigod crash handler

so i tried to root my phone and install a custom recovery the phone was working good until i rebooted and ended up with this error
Secure boot error
cause :boot certification verify
then it goes to this screen (see image)
i can press up to go to download mode
and the pc is reading it as a serial port but the LG flash tool 2014 is not flashing it keeps failing to connect to the server or failing outright with the option to EXIT
i did download the VS980 kdz file
so im not sure how to move from here or if the phone can be recovered at all
any advice would be appreciated thanks
It your getting "network error" on the kdz method that's normal.. If you move the window you'll see that it's actually flashing.
I'll help you out in my guide you posted in

Well bro I was stuck with the same issue..
This happens to me when i flashed a wrong twrp recovery for lg g2 d801 and it was stuck in critical error i was also unable to access download mode ..
But my Good luck was that i recovered it by doing silly thing ?
So i do following things. But make sure u know the corrert version of your lg g2 to flash kdz file with lg flash tool and also must have lg drivers intalled.
Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode

It happened to me several times. You should be able to boot into system though. If you kept a backup of your stock recovery, you can restore it and resolve this issue immediately.

Well i am not at all an expert in miui, infact this is my first mi phone. But i think this tool called xiaomi adb/fastboot tool can help u. Google it.... It is available in reddit. One piece of general advice : before any kind of experiment always keep a preparation for the worst case scenario. I think ur phone is stuck at boot. U can try to hold the power button for about 10-15 seconds to turn off. Also just relax and have patience... It will b solved. Let me know how it goes.

Nevermind I misread... If you think clarity or the firmware messed up your phone I could give you my kernel and firmware for you to restore it
Though if you're desperate for a solution, I'd transfer a ROM into your phone and start over with it, you can flash MIUI also by flashing https://drive.google.com/file/d/0ByWEieei-0nyMTR4R0dxWk9BTms/view after it
Your version of miflash is a little bit outdated! The last One is from may, last year if my memory doesnt fail. Install latest version of miflash and try to flash again stock ROM.
You can try also flashing stock ROM with miflash but in edl mode (emergency download mode) , instead of fastboot mode, but to do that you have to acess stock recovery, and then use this command " adb reboot edl", connect your phone to PC, and then see of detects, then flash then stock ROM. To acess stock recovery, press volume up + Power, if that not works, press volume up + volume down+ Power. Hope i helped
Ok I solved the problem using this method.
So I removed back cover, disconnected battery, connected the 2 points with a twizzer then flashed STOCK rom and it worked!! So relieved!
Thank you for the help anyway.

[HELP] Looking for last (or any) ota update.zip for D415

Hi everybody
I need to find an update.zip to flash it on stock recovery and attempt to repair the phone system.
Long story short..
I restore my D415 (previously with Lineage 14.1) to stock firmware (KK) via KDZ file and LG flash tool, then update it to LP with LG Mobile Support Tool and everything was good, then i tried to root the device with the LG OneClick Root (which i used several times before to root my phone without problems) but i don't know what happened during the batch process and now Download Mode has been replaced with Fastboot mode and the device hangs on the T-Mobile startup screen, so i can't flash a KDZ file again to restore the phone without a Downlaod Mode. The fastboot mode throws "remote: unknown command" with every command i tried (except fastboot getvar all; which shows "unlocked: no") even reboot doesn't work.
Tried everything even booting on Qualcomm Qdload mode (shorting the phone with test points) to reflash the firmware files but couldn't succeed because QFIL, QPST Software Downloader and BoardDiag they all threw errors.
I can access the stock recovery mode by pressing home button when the "erasing" screen appears after selecting "yes" on factory reset menu, so i need an official update to try to fix this phone, don't know if its gonna work or if this is a hardware issue but at least i want to try. Buying a new one is very difficult for me right now.
Thanks for any help.
