Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!

@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Hey all,
I restarted my phone yesterday and it was stuck in a boot loop for some reason. I tried to factory reset, but doing so still resulted in a boot loop. I then proceeded to attempt to flash stock, but the flash tool crashed while during the process. When I try to boot to download mode now, I get "Secure booting error, Error!: Boot Certifcation Verify". I know this also happens on the G2, and I know the process for fixing it. But when trying to use the same method with the G3, I can't access my filesystem from Linux. Any help? Thanks.

I was rooted before updating to lollipop, then tried to back dowk to KK with TOT and this happened, so I dont think I am rooted any more.
The better question is: do you have TWRP (custom recovery) installed? If you do, your phone can be fixed. If not, you are probably screwed.
Basically it sounds to me like your phone managed to flash the updated Android 5.0 bootloader but didn't update the LAF image (download mode). The old download mode doesn't work on the new bootloader, it gives the error you are experiencing.
Because you still have a LAF partition, and presumably a recovery partition (even if they are not working) you cannot access fastboot mode.
In other words, there may be no way to fix your situation.
As the hardware is fine there must be a method, but it might be something only LG can do.

I'm in the same situation now.
I was bumped with TWRP and CM12 installed. I wanted to unroot and go back to stock. Started a flash with LG flashing tool, but it was taking ages, so I unplugged the USB cable in the middle.
Now whenever I boot via either VolUp+USB or trying to get into a recovery I get secure boot error.
Is there a way to fix this ? Or do I need to send a phone to LG ?
This has happened to me today. Downgrading got stuck at 3%. LG Flash tool said to remove phone and plug back in. Any way to fix
Also, does anyone know if downgrading voids warranty or anything?

I didn't find a way to fix it, so I've just sent it to LG repair shop. They haven't yet looked at it so I don't know how much would it cost.
People just tell the service center that you were upgrading from KitKat to Lollipop when the problem happened
Evidence wise it support your claim since the OTA from KitKat to Lollipop overwrites the aboot, sbl, laf and recovery partitions and service center people ultimately cannot tell between failed OTA and a failed KDZ flash

solution for no download mode
Hi guys.
If you cant enter into download mode then you need to force your g3 in to qhsusb bulk mode by shorting the test point.
When you short battery must be removed.
After short your phone will be detected as qhsusb bulk mode.
Send me msg in pm for further help.
If u dont know the test point then let me know.

Hi! I just recently bricked my LG G3 D852, and I would really appreciate it if you could PM me and help me out here.

Try this. This will revert to factory default, tons of bloatware included ?
Sent from my D855 running CloudyG3 2.3 with Gabriel5 kernel.
Don't forget to smash that thanks button if I, or someone else helps you, guys!
First of all I want to Thank cybertag (a member at reddit.com) whose help made me find this solution. And sorry if my English is not good, it is not my first language. As I don't have enough posts here, XDA restricts me to post external links so this is the best I could do. I will add links to the files needed once i am allowed.
A few days ago I was tinkering with after my lg g2 ls-980, the sprint version of lg g2, rooted but no custom recovery installed and I made my first mistake of changing the model number from ls-980 to D802 in built.prop file thinking that it will only change the model number shown in the hardware information and restarted the phone. Once my phone booted up after that restart everything was crashing. There was a huge number of crash reports popping on the screen and I was not able to use anything. So I downloaded the .tot files of the stock firmwares LS980ZVC and LS980ZVE (don't know why but I downloaded both) along with the .dll file needed to flash the firmware for ls980 and when I tried to flash the firmware booting the phone in download mode and using the LG Flash tool but it gave me an error saying that the firmware does not match with model number of my phone. Both firmwares gave the same error. My phone and the flash tool both were thinking it was D802 while it was not.
Now i made my second mistake and downloaded the stock firmware for D802 and flashed it using LG flash tool. The firmware was flashed successfully without any error, but when the phone booted up after the flash the touch screen was behaving funny and phone restarted every 15-20 seconds because this firmware was not meant to be used with LS-980. I was unable to do anything the way touch screen was behaving.
I spent most of my time for the next few days googling for the solution and searching on XDA and also on reddit. I found multiple threads reporting that a generic no-check DLL file is the savior in this situation, but when I tried to run it I get continuous errors telling me the following: "CrossDL [D8012] to [LS-980]". Then i found this thread by cybertag on reddit which lead me to the right direction. It suggested to hex edit the .tot file for ls-980 so that the flash tool thinks that it is for D802. So I grabbed a hex editor and found the first mention of LS-980 and changed it to D802, saved the file and tried o flash it but it was still giving different errors. Then someone suggested it only works if you edit the .tot firmware in linux based OS. So i installed ubuntu OS on a virtual machine and tried editing the firmware in that OS using Bless Hex editor, still no success in flashing. Then I tried editing in pinguy OS but in vain. Then I found FlexHex for windows and used it for editing the LS980ZVC.tot firmware did the same thing, found the first mention of LS-980 and changed it to D802, saved the file, flashed it and bingo! the flash tool gave no error this time and flashed the phone successfully.
Now there was another problem. When the phone rebooted after flashing the firmware it got stuck on LG logo forever. And when I tried to boot it into download mode, the download mode was gone and it took me to fastboot mode. The phone was stuck in bootloop and there was no download mode anymore. Now after more searching i found a method to resolve this problem. Downloaded the aboot.img and laf.img partitons for LS980ZVC and flashed both using fastboot commands. Tried to boot into the download mode again and it worked and i was in download mode one again. When I checked the phone model was changed back to LS-980, the original one. Flashed the LS980ZVE firmware from original .tot file as it was the latest version available to date and it flashed without any error. When the phone rebooted after completing the flashing process, it was as good as new, up and running the original stock kitkat rom for this model. Tested and tried everything and never noticed any issue.
Thank you @tauheed that will help a lot of people I'm sure.

Hi sir!
i think i got just the problems with yours, but i not sure how to get my phone into fastboot mode no matter how many i press the [power+volume up] it just start up and stay at lg logo screen forever.
Can you explain how to get my LS980 into fastboot mode step by step, if i can put it in fastboot mode, i think i can fix it. please help

Please refer to my picture below to get better understanding what i'm trying to explain and again i'm sorry for my bad english.
My pc can detect my LS980 but not in fastboot mode, i mean if i try to boot into download mode then my pc won't detect it.

the only possible option is to flash the aboot.img and laf.img partitions. But we need to find a way to do so in your phone's current state. Things can be a lot easier if you could manage to get into fastboot mode.

You have to edit the first mention of the model number in the hex editor. Don't mess with anything else.

I am the same problem as yours with another phone I have. It is a D800 which was wrongly flashed to D802. After flashing the D800 firmware with the model name edited, it is stuck on LG logo and it won't go to download mode either.
Not yet. I'm still waiting...total dead phone now.

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.
I ran into the same problem and now i'm stuck in downloadmode!
Does this method work? Or is there any other fix yet?
Thanks in advance!

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.
i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.
i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!
Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english
I flashed 30c firmware with flashtool 2014 over rooted 21a (i think) on my D855 from Greece. I selected the normal flash to keep my files and apps, phone mode: DIAG and didn't clear the update registry. Phone worked normal for a week and then went into a boot loop. The phone randomly restarts and goes into loops for a while and then snaps out of it.
I have tried the following and none have fixed the issue:
-Replaced the battery.
-Upgraded to 30f over lg pc suite hoping it would fix it but it didn't.
-Flashed 30c and 30f over LG Flash tool with CS_EMERGENCY mode and cleared the updated registry.
-LG Flash tool wont flash any older lollipop kdz I tried. The phone screen flashes once but stays at 0% and then I receive a phone disconnected message.
-Put the device into safe mode and used the option on lg pc suite to fix upgrade errors. Didn't fix anything lol
-Tried factory reset. Nothing happened after I selected the yes on the confirmation.
-Tried to use LGUP hoping to install a lollipop kdz but it gives me an error message that I have to select a known model. Restarting the app and the phone didn't work either.
-Tried a guide on how to unroot and return to stock with the kitkat .tot file .
I really have no idea what else to try. Any help would be greatly appreciated.

I tried removing the battery while connected to the pc via usb already. The other trick that involves editing a file requires root.
My phone started flashing the blue screen of death today so I finally took it to LG so they can check it out. Either way thanks for trying to help.
Hi Everyone.
I'm in a big mess.
My LG G4 showed as H815 in device information (But it was F500L) . It had 5.1 (LP).
To update it to 7.0 (N) I flashed the TOT file for N with version H815 thru LG UP.
Now it did complete to 100%. The phone rebooted and showed error like " Central App not loded" or something like this.
I tried again to Flash the TOT file thru LG Up. It went till 21% then shoed error command not recognized.
I triedLG bridge. It shows device as F500L.
Although LG Bridge says update available, it could not update either.
So the problem is I flashed wrong version. My phone is F500L and its showing "firmware update" when plugged into USB with PC.
In LG Up it shows as H81510H
Please guide friends....

Why u flashed the tot file?
For your Location (Korea ? ) there is an official Update to 7....
Look here: https://lg-firmwares.com/lg-f500l-firmwares/
or this Link: https://lg-kdz-firmware.com/
You should use LGUP again and flash back with stock 5.1 or 6.0 kdz, follow the link.
Hope will helps you otherwise reply

Okay, that Sounds good Yes really..
I think the Probelm is in LGUP´s dll, you must replace the LGUP_8994.dll with the L500F kdz from.
Download the Tool LG Firmware extract, Link from my GDrive:
https://drive.google.com/file/d/1NTzwI-qLBpIgTov5PC4THZJWbAOhJDO3/view?usp=sharing
Start the tool and load the kdz in, then you see some files in the tool. Mark the lgup8994.dll and extract it, close the tool.
The dll can find now in the Folder of LG Firmware extract tool, rename it to LGUP_8994.dll
Copy that new dll and put into C:\Program Files\LG Electronics\LGUP\model\8994
The old LGUP_8994.dll remove to desktop and put the new dll in here and start again with LGUP.
Please point LGUP to Refurbish and NOT to Upgrade. The old dll that was in the Folder is for the Nougat tot file and the H81520p kdz only.
Hopefully thats will works for you, normaly it should !

Well this is not working.
LG UP recognizes my phone as H81529a. So it doesn;t let me flash F500L rom.
When I extracted 3994 DLL from F500L KDZ and replace in LGUP folder and start LG UP. It shouts wrong version DLL.
Is there any way I can make LG UP to recognize my device as F500L and Not H81529a.
LG Bridge recognizes it as F500L though but it doesn't update my phone either.
Please help n guide

Hmmmmmm
Okay, the H81529a Header says LGUP that is a G4 H815 with Anroid 7 ( 29a) on it. Okay, the LGUP_3994.dll wont work for your F500L kdz. By the Way..wich kdz you try to flash? is it a MM one or the Korean Nougat ?
On my H815 i had the 29a after flashing the Nougat tot file too and came back to MM ONLY with H81520p_00_0314.kdz other kdz for my H815 did fail too.
This Problem with LGUP is only the dll file...so you must find a working dll for LGUP.
Maybe you download the Korean Nougat kdz and extract the dll like the last posting before and flash the Korean Nougat, i think the Korean Nougat has 29a too, so LGUP should work.....
Or find a F500L20p kdz file...
I don´t know what to do yet. Sorry.

Well...
I have been able to sucessfully flash H81520p_00_0314.kdz on it.
It starts but no signal / network.
I'm from India so I think the version I flashed doesn't match with Indian Band.
Now what to do ?
In India following works :
2G network GSM 850 / 900 / 1800 / 1900 MHz
3G network HSDPA 850 / 900 / 1900 / 2100|TD-SCDMA

For my undstanding....
1) You have still H81520p_00_0314.kdz running on your Phone ? but no Indian Band ?
2) What Header is LGUP showing now?
If you have H81520p_00_0314.kdz on it, you are able to Downgrade to ever Version you want, H81520p_00_0314.kdz make it possible only !
So, find out your Rom for your Location and flash it with LGUP. Keep the 8994 dll it comes from H81520p_00_0314.kdz in the folder and flash.
After downgrade with LGUP (Refurbish Mod ) do a Over the Air update on your Phone or via LG Bridge and do "correct update Error" instead of "Search for Updates" and normaly its works.
Follow this Links for the Roms
http://storagecow.eu/index.php?dir=Xda/
https://lg-kdz-firmware.com/
If you are unsure what rom you must get, go to https://lg-firmware-rom.com/
and type your IMEI in and watch for the results.

Well
Problems just dont seem to end.
I hooked it up with LG bridge.
It showed model as "G4".
No version no code just G4.
I started to update it (thats before I read your msg)
Update stopped in between and phone turned off. I unplugged it and pulled out the battery. Restarted.
It showed LG logo and agained turned off.
I tried to reset by pressing Down vol n power button.
Options came to reset n I reset it.
Now again turned on. It showed optimizing android.
Stopped at 4 of 32 app and screen went blank.
Now LG bridge reads it as L500F at place of G4.
Hooked up again in download mode and LG UP disnt recognize it. Again restarted.
LG up recognized as H81520p.
I reflashed thr H815 20 p kdz.
Completed successfully.
But the problem is again same. It shows optimizing android and screen goes blank after 3 of 32 app or 4 of 32 app.
Have I messed up the recovery ?
I am able to go into download mode and LG up reads it as H81520p.

I will do my Best my Friend.
I don't understand why the optimizing Process stops....
Maybe there is something blocking the process.
My only idea now is to flash Twrp on it and wipe all chaches. Davlik,Data and Cache and let the phone boot up and see what is going on. This is the working TWRP for G4 on H81520p

But for twrp flashing the Bootloader must be unlocked. You can do this on lg developer page ( https://developer.lge.com/resource/mobile/RetrieveBootloader.dev ), type in your IMEI and you get a unlock.bin via email.
I think you know the process for Bootloader unlocking otherwise i will guide you.

Hi
Can bootloader be unlocked in LG G4 MM ?
Initially when i flashed nougat TOT on it, the firmaware update page was either in korean or chinese then after nougat TOT flash ot became in english.
Could it be that the recovery is also overwritten ?
Plz point me to bootloader unlock for it.
Many thanks from India

Hey.
Yes you can unlock Bootloader in MM too.
After the bootloader is unlocked, the Phone will reboot and do a Hardreset itself, you can´t do anything to block the Hardreset.
Notice: After flashing in any Versions the Recovery will be deleted too !! Example, if you have TWRP on the Phone and flashing any kind of firmware, the Recovery with TWRP in it will be deleting..thats normal in the flashing process.
BUT you CAN´T unlock the Bootloader yet ! You must enable the Developer Mod in the Phone first and set OEM unlock.
Your Phone does not boot up correctly at this moment, this Problem MUST be solved first !!
Did you try a Hardreset ?
Switch Phone off, pull Battery and place it back. Press the Volume down Button and keep hold and press Power Button and keep pressed, after LG Logo is showing up, release the Power Button for 1 secound but still keep Volume down pressed. Press Powerbutton again and hold pressed until the Green Android thing is showing up, release both buttons now.
In short: After Battery was pulled and replaced..
Press and hold VOL -
Press and hold Power
after LG Logo is showing up
Release Power 1 Sec. and press again and hold until Android puppy is showing, release both Buttons.
Now the Phone should boot up and do the optimazion process correctly.
If not, then i have no more ideas. Maybe flash a MM 5.0 Version over the MM 6.0 via REFURBISH option in LGUP
Hopefully something works for you.

SO Finally it's dead.
I tried to hard reset and the puppy appeared and then it rebooted. Again went to optimizing apps. Stuck at 14 of 32.
Became unresponsive.
I pulled out the battery and reinserting after 20 sec.
Nothing.
After several battery removal and reinserts, I managed to get it in download mode.
I was trying to Flash H815 20p KDZ again as it was working initially. But at 50% process of flashing, it shows error of USB Disconnected and phone screen went blank.
Since then it was neither starting nor getting in download mode. Tried everything.
It doesn't even show after connecting to PC.
Dead as dodo.
I looked at it with more attention. Removed the battery cover saw the model on mobile body,
it has model no H811
On box the model no is H815
LG Bridge recognized it as F500L.
IMEI No search says its F500L.
So basically it looks to either a refurbished phone or a fake.
I bought it thru eBay on 18th Jan 18. So I had to claim refund against a faulty product.
I suppose I'll get a refund, I will skip replacement as it's likely that the seller might again push a refurbished / fake phone.
End of the story till then.
If I dont get a refund I'll revive the thread.
Thanks to FOTO AG and XDA for support n advice.

You should have hexedited a F500L tot(wich is your motherboard version) and changed the LGX to H815, saved the file and then flashed. That could been solved your issue and turned your phone back to F500 with a functional and booting system
