it will not work , sprint version was v450pm cant use this firmware

EDIT: I don't need this anymore since I've fixed the problem
Hello, could you help me by uploading your QFIL partitions dump and its rawprogram XML files? I accidentally hard bricked my V500N by erasing its entire partitions, and I need them to restore the download mode. I have tried to use the dump files of the Sprint variant, but it caused LGUP to have a cross-flashing problem with every ROM, because of the incompatible dump.
I will make a tutorial once I'm successful in restoring my phone. Thanks.

[HELP] tot file for F180K for lgnpst

Hi everyone,
I really need your help, I need a tot file for F180K so that I could return to the official stock version.
So dump of me, I flashed KDZ to convert it to E975 but i don't get a network signal anymore. I flashed back to korean rom, f180k20g (jb version) but to no avail, still the same. If someone kindhearted would generously provide a tot file for this device, I would greatly appreciate it.
P.S.
Thanks to the guys at the forum, I learned a lot from you.

Hi,
I have the same problem with the mobile network. Now I try to download the new F180K201_00 and I'll flash it hoping that it helps....
But I have a copy of F180K10H_00 that suit you.
But a question. Did you try factory hard reset and wipe? Did you flash the right baseband?
Ciao

Yes i tried factory hard reset only. I don't know how to wipe. I already tried F180K20G firmware but it is still not working. I haven't flashed any baseband because there is no available baseband img file yet for F180K. I already tried to flash anything from E97510a philippines or 10b HK version but still not working. I hope someone can provide a tot file so that we can boot back from scratch.
EDIT:
The only thing that I regretted is that I didn't back up the efs partition before I flash. If only I have learned about the freegee stuff earlier.

Hi I just found the baseband for all F180 models in a Vietnamese website, there is a file .bat to execute for all models.
Source:http://www.tinhte.vn/threads/optimu...p-root-recovery-up-rom-4-1-2-fix-loi.1816719/
I droped the file on mediafire here: http://www.mediafire.com/?qbnu22y4sx7kf0n
I hope it works.
Wipe is easy with adb.
C:>adb reboot recovery
then waiting....waiting... waiting (it takes long times, also more than 10 minutes
If someone need F180K10H_00.kdz i can upload it. Tell me only where I can copy it....
You can get the KDZ from here: http://lg-phone-firmware.com/index.php?id_mod=20

Yeah I tried it already but it's not working. Probably I need to erase everything first, CACHE and SYSTEM. How do I get to fastboot mode on the phone? Pressing Volume down + power only brings me to Factory Reset Mode.

Yes bro, I think I need the ICS kdz first so that I can unlock my bootloader using the freegee. I can't unlock it using the freegee-beta for JB. I already tried the adb reboot recovery, factory reset, still nothing. Appreciate it bro if you can upload it.
I just convert my F180K to E975 EU , rooted the phone and flash the baseband , all is OK :good:

How To Get Working Apn + Hotspot After Upgrade to NCQ26.69-64+ or With SPerry XT1766.

You Need From firmware.center / firmware / Motorola / Moto%20E4 / Stock / XT1766 /
SPERRY_SPRINT_NCQ26.69-48_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip Which Is Not For The XT1766 if You Flash This You Will Loose The Baseband And SoftBrick The Phone .
And From firmware.center / firmware / Motorola / Moto%20E4 / Stock / XT1766 /
XT1766_SPERRY_SPRINT_7.1.1_NCQ26.69-56_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip This One Have The Ratio And Modem And FsG images Of Your Phone Thats Why We Need It .
Lets Begin , if You Have This Phone You Had Noticed That After Upgrade To The Last Version The Ability To Add Apn And Modify Them And The Hotspot Wont Work Any More This Is Because The Locked Everything Up For No Reason Well Money Is the Reason , We need to Extract XT1766_SPERRY_SPRINT_7.1.1_NCQ26.69-56_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip in a folder and SPERRY_SPRINT_NCQ26.69-48_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
in other folder , you must know your way to flash servicefile.xml on linux or windows no details here and bootloader unlocked , well that is easy , now we have to put the files : the 2 OEM files , the 4 System Files , boot.img ,
{{{ bootloader "NO NEED" This Work Before Just Because v48 and v56 have the same bootloader version }}} , recovey.img from SPERRY_SPRINT_NCQ26.69-48_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip inside the folder that have the XT1766_SPERRY_SPRINT_7.1.1_NCQ26.69-56_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip firmware and replace those files , optional for rooting you can replace recovery.img with the Squid2 TWRP recovery.img file and The boot.img Patched Fixed F2FS kernel which is based in the stock firmware kernel sources that we are going to flash here and then flash supersu inside twrp , Well Thats It after Flashing This Downgrade Custom stock you will have back the ability to ADD apn's Again And Use The Hotspot included in the Stock Firmware , Cheers , Thanks To All The People Involved in the development for Perry Moto E4 Thanks Everybody i hope this help somebody with the XT1766. :laugh:
EDIT HELLO
Things Have Changed Dont Try To Downgrade Bootloader or The Phone Will Get Hard Bricked , Why well bootloader versions on new firmwares have been upgraded please check all the information on the Bootloader/Fastboot
MODE Of The Phone Which Version You Have , Now For Example If You Are On Version NCQS26.69-64-5 you will need SPERRY_SPRINT_NCQS26.69-64-5_cid50_XT1766-SS_7.1.1_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml full package then extract and now you will need SPERRY_SPRINT_NCQ26.69-48_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml extract it too , Now Just Move The 2 Oems Images And 4 System Images And Boot Image To SPERRY_SPRINT_NCQS26.69-64-5_cid50_XT1766-SS_7.1.1_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml Folder Next Look for RSD_Lite_Motorola_XML_To_Batch_Script on Google Download it And Watch The Video Of Rootjunky on how to use it.

I flashed the Sprint firmware and had data working on my XT1766 after it got it's carrier update, the Sprint firmware does not soft brick the phone as I flashed it and can confirm it doesn't soft brick it, so you are incorrect in saying that.
I'm not sure if I did something wrong but after trying this, my phone kept saying, "phone stopped working". I had backed up my phone so I restored it. Any ideas on what might have happened?

The steps are there. Just don't use the root part if you don't want root. Once you switch the files, flash the service file.xml with rsdlite.

That's normal if you unlock the bootloader. Flash the no verity opt encrypt, or magisk, and it will change from bad key to n/a. But there will always be a message if you unlock the bootloader.
I know you said you don't need root, so that bad key message is there to stay.

N/A will be there. But you can flash a new boot logo to kinda hide it. Instead of a black screen, any logo you want, maybe with a white strip at the top to hide it. I'll get you a link.

Just don't accept the update. You can root by flashing magisk. You will still receive update notification. You'll need to disable the moto update app. I forget which one exactly. But your phone shouldn't be able to do ota updates once you are rooted with twrp installed. The update will fail.
here is the root thread.

Thank you. I wish I had known this. I had to flash the stock recovery, etc for the updates to work. A little bit of an unnecessary hastle.

Ota updates will likely always fail if you have twrp, or have modified the system in any way. The ota performs many checks (assert props) to see if the system is clean. If any asserts fail, the ota will fail. Even restoring the stock recovery doesn't guarantee the ota will work.

LGUP Oreo DLL File for V30

I had this issue last night so thought id save people some trouble and share the the file needed incase you need to flash over 20D's KDZ file either to go back or forward.
Please unzip and put in C:\Program Files (x86)\LG Electronics\LGUP\model\common
Works with LGUP 1.14

1.14 is the latest. I found some other typos in other LG threads also calling it "1.4".
Sent via open market LG US998 V30/V30+
Damn.
I had it working with 1.14, but I thought I had the wrong version. So I uninstalled it.
Now I can't get it to load - wrong dll for VS99620a.
Plus I wanted the developer version of LGUP.
Pretty sure I need the Partition option to flash other-model KDZ.
Hi there,
I need some help because i fell so stupid.... I cannot use the patched DLL for uppercut in order to flash the newest Oreo KDZ for H930...
I installed LGUP 1.14, USB DRiervs, etc... Download and uncompress uppercut 1.0.0.0. I downloaded the patched DLL 1.0.31.9. Even if I copy that dll on the uppercut folder or wherever i copy, the version shown on LGUP is always the 1.0.28.9... SO I cannot flash the latest Oreo KDZ
Help please?
thx in advance
you have to run lgup.exe not uppercut shortcut.

Hi, has anyone been able to revert back to N from O, please? I upgraded my H930DS (Hong Kong) to the Open Euro 20d ROM, but haven't been able to go back to N using either the patched LGUP or UPPERCUT (… I'm not happy with the limitation on the use of the dual SIM). With the phone in download mode, the error I get is "DLL for H93020d is invalid. Please install valid DLL package(*.msi) for the model". I get the same message if I try both methods with the phone in its normal operating mode. Thanks for any help.

ROM or the KDZ? You probably mean the stock open European KDZ.
For the KDZ, go to the thread. Instructions are there.

Thanks, but I think the operative word in that quote is "should". I've tried that method with the phone in download mode and with it in its normal operating mode, but LGUP no longer recognises my phone model. I can get the LGUP pop-up with the serial port but the pop-up shows the phone as an unknown model, which I guess is the issue preventing the firmware update.
The version of LGUP_common.dll that I'm using is 1.0.35.3, which should be the latest. Its digital signature is dated ‎Tuesday, ‎19 ‎December ‎2017 3:33:29 PM. Its MD5# is c3df15812c1294028bfd330eb725519b.

Here is the reply I received from LG about reverting to Nougat (I asked them to do it for a fee):
"Dear Peter,
Thank you for contacting LG Customer Support. I apologise, but please be advised that we cannot put back your the previous software of your phone.
We suggest that you perform Factory Reset to your phone. This will not restore its previous software, but can fix issues of your phone. However, this will delete everything saved in your phone memory. You may back up first your files.
To reset:
Go to Settings
Select Backup & Reset
Select Factory Data Reset
If the issue will still continue, please let us know so we can assist you further.
Thank you. Have a great day ahead.

… However, I was able to flash my LGH930DS to Oreo for the LGH930DS using LG Bridge after a few attempts (I couldn't get UPPERCUT to revert my phone to Nougat), resolving my issue with using the dual-SIM with the cross-flashed firmware and thus obviating my need to revert to Nougat.
Looking for some guidance please & thanks.
I have a H933, converted using the Frankenstein method to a US998. Then Unlocked BL, TWRP and rooted. Upgraded to US99820d
I would now like to flash back to stock H933. I have installed the Patched version of LGUP. I have extracted the DLL here into a common folder inside the model folder. I put the phone in Download mode, plug it in and then launch LGUP (patched). it finds the device but then errors saying the DLL is not valid for US98820d and to get a compatible DLL.

Lg G8 AT&T full firmware backup file

Please can someone help me with their full firmware backup so I could restore mine. I mistakenly wiped both slot A / B and now my phone won't boot up. I just bought the phone and to my surprise AT & T doesn't work in Europe.

No still hoping someone would upload it.
Guys just crossflash with lgup, somewhere on XDA are instructions. Then at least the phone would be working.
It won't work I have tried it except you know another way. It's lock to AT&T America.
Hi I came by this post about an LG g8 att model. So I have such model and going to wipe it and flash a custom rom on it.
Perhaps before I do that I can put the original file here. Can someone guide me and point me to the proper page to do this?

Another utility to use for backup and flashing back would be the bkerler edl python utilities.
Search for it and you'll find his github page, and on it, he even provides a bootable image you can flash to a usb drive, boot it and it's ubuntu with all the utilities and all dependencies resolved.
I've used them many times and it's the first thing I do is use them to backup original rom on the device. Sorry, don't have at&t, just sprint.
Keep in mind there are some partitions you NEVER want to flash from someones backup, they contain imei and s/n.

Does anyone have firmware for ATT G8?
So I tried many ways, as an unexperieced rom flasher, and so far had no luck.
The LG G8 ATT phone doenst even want to boot into recovery mode.
Also connected to a PC via USB and entered some commands via ADB tools and even then it will just reboot the phone.
Anyone got a clue what I am doing wrong?

V450PM LG V50 Sprint update to system 20N

Hello guys, so after spending a lot of time doing research on which partitions to extract to flash. I found out that the partitions on the link did the trick. I have 2 Sprint V50 same model one is rooted, the other is not, made the backup with Qfil from the non rooted and flashed those onto the rooted, that did the trick. Only use Qfil to flash partitions, do not use TWRP, it'll fail and your data will be erased to get it to work again!
The files are the one's I used, so I upload those to you guys! Hope it helps someone, if you have a doubt, just ask I'll be happy to help.
When I have some time I'll try to make a guide of it. If a new update arrives I'll update this post with the new files!

thx bro.
Strange I've never had any issue with flashing these in TWRP as long as I clear data/userdata. Then again I prefer starting fresh on a new OTA.
Thanks

Did you ever figure this out? I can't seem to gain root anymore with magisk flashed images... the system sticks at the lg logo... once I restore boot_a it boots fine

But... My phone won't go into download mode any longer. It did prior to the restore service. Also, I was not able to locate a kdz image for this phone.... Only the international version. Any ideas on how to restore download mode and flash a custom rom?

What happens when you try to boot download mode? I'm not sure which kdz you are looking for. If it is sprint, I recommend looking for the v50 sprint backup files shared on xda. It isn't kdz, but result should be more or less the same.

Nowadays, I can only connect via Wi-Fi calling while the cellular connection no longer works, so I'm guessing that T-Mobile is doing some IMEI-based blocking on their end.
