Try to explain better! Do you have installed custom recovery?

no i installed a modified multi language rom from "needroom" did every as told and everything looked fine during the upgrade and when i was finished i got the green circle that says it was ok but when started it up it went in to boot loop and said "TOOL DL image fail!" but after a while its totally dead.,when i try now it wont load in any software into the phone ,just starts up the purple pre preparation on the SP flash tool but when i connect the phone it stops .cant get it into recovery mode or anything,just completely dead. i would rely be thankful for some advice her

Maybe the package you've tried to install is corrupted.

most likely, but is there anything to do with it or is it over for it.

Most likely your device is unusable. Without any recovery, I dont think you will be able to do anything. I am sorry.

OK a 200$ experience richer , thanks anyway

method to install original rom android 4.4.2 in lenovo s850
i have found the perfact solution to install original 4.4.2 rom on lenovo s850...so for that you have to donload rom from the link in notepad file...i have uploaded notepad file and download link is in that it is about 1.1 gb...so it will take time to download and after that what you have to do is open flash tool and then check da dl check sum and then extract the file you have download of 4.4.2 android and then in flash tool click on scater loading and browse to the the extraction location and in extracted folder there will be a folder somethinf target bin in that folder select scatter loding file of lenovo s850 and then just simply click on upgrade firware and then switch off your phone and then wait to process complete untill green circle come...and if you dont have flash tool...google it and download...thanks i hope this helps someone...:good::good::good::good:

Personally i don't really like flashify or any other similar apps.But as you are a beginner at all these follow this simple steps.
Can you boot your phone?
Try using the official App provided by TWRP
Go to Google Play Store and search Official TWRP app,download
Go to the application and select "TWRP Flash" option,after that select your device model and then select the latest TWRP version(3.0.2.0 or 3.0.3.0).
After all these click the bottom Download TWRP.
That's all.

I see that you have messed a lot with your system partitions.
I'll try to find something helpful.
Till then try checking if you can use system upgrade.(To go for example to lollipop while it may save your phone and also be able to flash the correct laf.img)
Question:After you finished the procedure on flashing the laf.img(for d851)(also you can flash the 10d laf.img as the OP said in the guide)did you pull the battery out and Boot to download mode(manually)?
How to get to Download Mode

yes i did try to boot into dl mode manually..

You also did pull the battery after flashing laf.img(10d) for D851 Model?
So... I think that after you tried doing all these and nothing worked, you'll be unable to get Download mode back,but let me check some of the system partitions and check if you can manually insert the laf.img file.

Somehow you can insert the laf file to your phone but it needs extracting (the laf.img) to get the proper file.
I found the location of the laf file.
But if anyone can be found with D851 can send the laf file here for you.
Two other solutions are:
1.Staying without dl mode? Maybe.
2.Buying a new motherboard.

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.

Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

With flash tool goto device manager on pc.
click ports and com get into settings on it and change com port to 41
and have device in download mode powered off volume up + insert usb cord from pc

@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.

Thanks for your reply guys.
I manage to flash it with LGUP with a TOT that I downloaded.
Thanks.

Congrat @imider ,
maybe you can share what you did to fix your G4

Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.

lg g4
Hi. I have lg g4 h81010o android 5.1. I put custom firmware and decided to fix build.prop. after that it at me didn't turn on. and I accidentally flashed it with another firmware.through qfil I restored the com port..but the LGUP program doesn't define my model..driver changed and LGUP version does not help. I think it's because I changed in build.prop..please help me find a solution

Mix 2 bricked?! Flashing went wrong. Need help please.

Hey guys,
so this my problem:
I got the Mix 2 with the Chinese ROM. With the XiaoMiTool by Francesco Tescari I updated to the Global ROM V9.1.2.0 because I didn't want to wait to unlock the bootloader. This worked but I only had the choice to set China as my region. Since this was a common problem with updating the ROM without unlocking the phone I unlocked it and waited for 3 days to unlock.
Today I installed TWRP and installed the ROM xiaomi.eu_multi_MIMix2_7.11.16_v9-7.1. After this I was stuck with the Mi bootup logo. In TWRP I deleted cache, system, data. This worked EXCEPT for system. I thought updating TWRP to the newest version would help solve this issue. But since I'm new to this I didn't update it within TWRP but just installed the newer version via the commandfastboot flash recovery twrp.img. The result is that I can not get in recovery mode anymore. The only option is fastboot mode or the regular Mi logo endless boot.
What I tried so far: EDL flash method via adb/MiFlash but both don't work. The XiaoMiTool won't work too. The Mi PC Suite won't recognise the phone. When I use the edl.cmd the phone will go black for 2-3s and then return to fastboot.
I guess the problem at this point is that usb debugging is not turned on since TWRP installed the EU ROM and I could never get in it to enable the debug mode.
I couldn't find a solution to solve the boot up problem and can't seem to install/flash a new ROM at this point.
So what can I do? Do I need that special usb cable? Will the EDL points help me?
Maybe/Hopefully you can help me out.
EDIT:
When I turn on the phone it will directly go into fastboot mode. A normal start is not possible anymore?!...
EDIT 2:
I am now running the latest Global Rom this guide did it for me: en.miui. com/thread-1351514-1-1. html

Good to hear you got it up and running.

hey - how did you get mi unlock to work? im having this problem: mi unlock tool 2.3.803.10. it won't show the mi mix 2 as connected with xiaomi drivers, only with google drivers it will show as connected and then let me click unlock. however, it stops at 50% and shows error "couldnt verify device unkown error (-1)". ive logged on to i.mi.com and located the device through find device. does anyone have any pointers how i can unlock, because i want to switch to global dev rom and miui updater wont let me update through system with error "android version is different".

I've used MiFlash Tool, and the problem was fixed. Sahara Error occurs when you take to much time to flash after booting to EDL, you only have few seconds to flash util the port is closed for writing. QFIL takes around 20 to 25 seconds in caching the files so use MiFlash and It'll flash. Best way to do it is:
1. Install and setup MiFlash for flashing.
2. Open MiFlash and select your Firmware's folder.
3. As soon as you connect the phone refresh miflash and hit flash.
If everything goes well you'll flash will be successful else try again.

I tried doing as fast as a could too on mi flash and it would come up as trying to connect to com4 port something in the status and would eventually come back to same error in the picture.

first uninstall zuk drivers and qfill and disable driver signature enforcement (Google it how to do it) then install zuk drivers and qfill use original cable and your phone will get flashed

Follow the instruction from this post
https://forum.xda-developers.com/lenovo-zuk-z2/how-to/zuk-z2-baseband-flashing-guide-t3715121

Do not listen to anyone telling you to use miflash, only use qfil otherwise you WILL encounter other issues because qfil is the only way to reach the deeper partitions that mi is unable to... Other issues may range from no volte, calling or signal problems etc its just easier to do it right the first time.
