error when flashing ATT LG C900 Quantum firmware. - Quantum General

Hello everyone...I used the instructions written in the development section. However when I get to press start and ]plug the LG C900 in emergency mode for flashing it gives me the error " ErrNum501 Load Image" I've been searching and searching and cannot find a proper answer to troubleshoot this. I need to reflash my C900 or I have to send it to LG repair. Thanks

Never mind.... using windows 7 OS...I just needed to use the program as administrator to flash the phone..runs like a dream...

It's good that the flashing sequence has been figured out already for when the time comes that we can make custom WM7 roms.

I keep getting the 501 error when trying to crossflash an ATT Quantum to Telstra firmware. I want to do this so that I can get the network settings tool to work. The network settings tool only works with Quantums from certain carriers.

What version of Windows are you running?

Win7 64, running in XP SP2 compatibility mode as administrator

The Telstra firmware will only work on C900K phones, American and Canadian Quantums are C900 and C900B respectively.

2. Unplug your device (if it's plugged).
3. Put your focus in download mode (I found this from Omnia forum), as astaccz already stated, press Volume UP + Camera + Power button, then after you see Exclamation Mark inside Yellow Triangle, release the button.
4. After the driver installed, Run the application (I use the 7.21 version) then load all of the files needed. (nb0, bin, etc)
5. Plug your device !! The Start button will be clickable now !!
6. Press start, and enjoy the flashing progress.

That converted my focus to Rogers i917R instead of AT&T i917
2. Updated it with ZUNE untill 7.5 version without problem
3. Did cable/Wifi trick with Zune to get latest update 7.8
Tested everything and working good.
Only issue is not able to download NOKIA apps.
If anyone has any idea how to do that then it will be great.

You should not have any issues, but if you still do, download (with WiFi) Network Profile from Samsung.
I'm using Rogers ROM on my AT&T for a long while with no issues.
I am a lost soul !! All of you might think I am a basic Samsung Focus 1.3 owner that has a phone which awsa interunlocked by windowsphonehacker.com/ tool
I am running Windows Mango and I want to upgrade to Windows 7.8 I Have seen many threads and videos for doing that, have even seen Tools which allow the deployment of the OS version I am talking about, but the real question I have in my mind is, wheter my Unlock and sideloading apps work on that upgrade ?
I know myphone would be on 7.8 but will I be able to sideload apps and whether my Windows phone hacker tool work ??
I in simple words want to know whether Iwill have a true unlocked phone and if yes, then can somebody point to a thread or suggest to me how to go about it in a simple and concise way.
Thanks a lot. to all of you !

[Q] Cannot install any rom / cannot restore to stock (T-Mobile D801)

Long story short, I deleted my backup rom (Don't ask Please cause I already know)
I am running TWRP 2.6.3.2 and it does NOT let me install any rom (4.3 or 4.4) I constantly get the error (Error executing updater binary in zip) for every rom zip I have downloaded.(AOKP)(PA)(CM 11) etc...
I've tried the Return to stock guide http://forum.xda-developers.com/showthread.php?t=2432476 in General Discussion, and I consistently get stuck @ 49% when restoring the firmware.
I also cannot get the LG Mobile support tool to download a new firmware for the phone itself.
I do have access to sideload via TWRP but it is useless because every rom gives me an error.
Do I have any options left or do I just call it a week and enjoy my $600 paper weight?
Please any help would be much appreciated!

Can you get into download mode? If so, the LG Mobile Launcher should work. Make sure you have the latest drivers downloaded from LG. It should also be in the thread about using the Mobile Launcher. I couldn't get it to work at first because I didn't install the latest drivers. Just plugging in the phone to your PC won't do it. Also, if you do get it to work, the firmware that will be installed will be d80110g, not d80110c that came with the phone. There is no info about this version other than the thread I started about it. Code Hustler tweaked ioroot to root this version and it is in the thread. Just search "T-Mobile software update" in the general section if you do get it installed. Good luck!
Sideload the latest twrp recovery and then pick your rom and retry make sure you are correctly wipeing systen dalvik and chache

Whenever I try to use the upgrade, it never even asks me for my IMEI , it says stuck displaying: Downloading software, but it never downloads anything. It could be a driver issue. There is just so many links on here maybe I really haven't installed the correct drivers??
Any links to drivers that works would be very nice if possible!

Problem Resolved / My Solution
Okay, after 12+ hours of trying every method possible on XDA I finally resolved my issue. I will update the first post just incase any others care or fall into the same dilemma I was in.
The LG Mobile Support tool would not download the firmware and it would NOT ask me for my IMEI to download it either.
So my solution....
***
Installed LG Mobile Support Tool then Installed the LG Drivers.
BEFORE I connected the phone to the computer. I opened the LG Mobile support tool clicked (Options on the top right).
When the dropped down opened, I clicked the (Upgrade Recovery) option. THEN, is when the prompt opened to ask me what my IMEI is.
Before I entered my IMEI, I connected my phone to the computer, then proceeded to enter my IMEI and hit OK.
This is when the LG Mobile Support tool SUCCESSFULLY downloaded the latest official LG firmware and installed it.
*** BE AWARE, with the phone connected to the PC, the prompt NEVER appeared to enter my IMEI.
*** But with the phone disconnected, the prompt came up every time. This might be the trick for some people.
*** with the IMEI prompt opened, I then connected the phone , entered the IMEI, then hit OK. BOOM HERPES....
Well I'll polish this up more later. I hope this works for every LG G2 Variant and not just the T-Mobile one (D801)
-Esteef
Well, good to hear that your phone works again... I see CM nightly has some TWRP install script in lastest build, and a TWRP version for CM 10.2 and CM11...

LG 20 H910-10Q to US996

My phone is a unlocked at&t h910-10q can I flash US996 Firmware on my phone so I can have a phone that does not have AT&T junk on it using kdz without root
Post a link to the KDZ that you want to flash and I will let you know if it is safe. I can't tell you if it will work, but I can at least let you know if you are going to brick your phone.
If it doesn't work, you will have to root it so that you can flash back to stock since there is no H910 KDZ.
@runningnak3d can I flash this zip https://forum.xda-developers.com/v20/development/rom-us99610k-stock-rom-twrp-flashable-t3691784 on my h910?

Hey @omnixech did you used the us996 kdz?
@runningnak3d any thougs about it?
I got busy on Friday and didn't get a chance to check. I will as soon as I get to work and post the findings.
@prismk @omnixech
The US996 definitely uses the same RSA key as the H910, so you won't brick your phone. I can't tell you if it will work, and I also can't tell you what the ARB version is.
Before you flash, you need to verify from someone that has a US996 what the ARB version is for 10l. If it is greater than 0, then don't do it, because if it doesn't work you will be stuck and can't flash H910 firmware back onto your phone.
Prismk, I understand why omnixech wants to flash the KDZ -- he / she doesn't want to root their phone. You already have root, so what are you hoping to gain?
-- Brian
@runningnak3d I was scared because the us996l zip flash all partitions except recovery, but I will give a try. Thank you!
The US996 ROM have UI differences, like the carrier name (hidden) on status bar and LTE icon. I can change that on H910, but I will have to use xposed and will break magisk
safetynet.
@omnixech If you did used US996 KDZ please update this thread, if it was ok I will use this KDZ too. I won't be able to use an app that my company use because I have root
No I have not used the kdz I most likely will not it is my only phone and do not want to risk ruining it.
I just was tying to remove all the at&t junk on my phone with out have to root, I do not like the current rooting method that is available for my phone leaving that warning message during boot.
I will just leave well enough alone until a better way to root comes along or I get a new phone what ever happens first.
Guys I'm a bit late, but would any of these firmwares work on my H990DS, since I live in the US and don't use the second SIM slot or the FM radio and want the UI changes and the VoLTE

I'm currently on LGH990AT-00-V11k-GLOBAL-COM-JAN-17-2018+0, even though the about phone menu shows V10g-AME-XX (for some reason that I do not know) on my rooted H990DS. If you could please check if this would work in a flash using KDZWriter (keeping boot and the kernel the same?) or flashing the TWRP zip that another user posted, I would be very grateful.

Sorry, the H990 handles the cellular modem quite differently. If it doesn't outright brick it won't have service.. Its why there arnt any Lineage builds for it.
It work for me. Network service working in my country. Except I cant access phone information in *#*#4636#*#*
So I cant lock to specific network. Other than that it runs much smoother without those AT&T bloat.
I did a test on the latest version US99610o_01_0202.kdz and it worked perfectly fine.
Just one note, make sure you are carrier unlocked before flashing to the new KDZ variant.
The only thing I found a little bit of annoying, at least on my case, is that you can't check for updates in the phone, I keep getting the following message "Your phone is not registered yet." Although there is a workaround (just google it), my way of fixing it is by updating through LGMobile Support Tool.
Hope that helps.
So it's possible to flash a us996 rom on H910? I'd like to know because the att ui sucks.

Yes, it is possible, I did the conversion from H910 v10q to US996 v10o.
However I am not sure if further versions in the H910, the ARB is incremented, making impossible to change the firmware, however if that is the case you will be stopped when LG UP will say "anti-rollback check failed" and abort.
In this case I used the patched LG UP: https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

Regarding the battery, I haven't found any real difference, but the ROM is way cleaner.
The way I did the conversion is doing the following:
Download the latest KDZ variant for US996: https://androidfilehost.com/?fid=673956719939828249
Further versions can be found here: https://lg-firmwares.com/lg-us996-firmwares/
Download the patched LG UP: https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
Make sure you install it in C:\Program Files (x86)\LG Electronics\LGUP or it will either read the wrong model file (if you had a previous installation of LG UP), or it will not be able to find the model file at all.
Put your phone into download mode (power off / hold vol. up / plug in USB cable)
Open LG UP and click the PARTITION DL radio button, pick the US996 v10o KDZ that you downloaded above, and click start. Make sure all partitions are checked.
Once it is complete, your phone should reboot into the new US996 ROM.

What is your mobile provider? Most likely LTE isn't working since your provider doesn't support the LTE bands from your device.

Did you use uppercut? Similar thing happened to my LG G5 and I realized you have to use Uppercut to do that sort of thing.

It may or may not work, it works with the G6 and V20, I’m not sure about V35. But it said it might.

Hi just saw your post and I have an AT&T V35 too so this should help:
1. Uninstall any prior version of LGUP currently installed.
2.Head to Post #18 at https://forum.xda-developers.com/android/general/lg-v35-amazon-project-fi-t3819470/page2
3. Download the ' V35_lgup_modded.zip' ; Unzip & install, then ensure the .dll file is also copied to the COMMON folder (C:\Program Files (x86)\LG Electronics\LGUP\model\common)
-If there's no COMMON folder, create one.
4.Shut down the phone completely(phone should also be unplugged), then get into download mode (With phone off,hold down the UP Volume button and connect the phone to your PC while still holding down the UP button) and release the UP button once you see 'Download Mode' on the display.
5.Now, there's no V35 AT&T Kdz file available online so the next best option is to use the Google-Fi kdz you tried earlier; So launch LGUP & select the Kdz file .
6. Next choose the UPGRADE option and flash.
7. Hopefully, that should bring your phone back to life and if not, try again with the REFURBISH option(will wipe user data etc.)
8.Lastly and very important, though you may be tempted to mess around with additional LGUP options such as PARTITION DL etc.; Remember the V35 is still relatively new & has low support so be careful - So far, cross-flashing seems to be fine except for Korean Kdz files but flashing partitions WILL currently cause you to lose either your IMEI/Serial Number or Both.
Cheers

Thanks. The guide works good to flash the fi .kdz but unluckly it doesn't unlock the at&t phone (as expected). I made the try. So people if you have an unlocked v35 branded you can go straight with this guide to unbrand it :good:

Thanks. The guide works good to flash the fi .kdz but unluckly it doesn't unlock the at&t phone (as expected). I made the try. So people if you have an unlocked v35 branded you can go straight with this guide to unbrand it :good:

Just want to be clear on one point. I have an unlocked att version (v350awm) of the phone and have followed steps listed above. i was about to upgrade to the fi kdz but noticed i have two options on the modded LGUP to upgrade, "Fota upgrade" and "Fac upgrade". I was thinking that it should be the Fota upgrade option.?

Hi, just stick to the 2 options at the top left - REFURBISH (For a total wipe, including User Data) or UPGRADE (To update without wiping User Data)
Cheers

Wanted to thank you to for the info. Am now using the Google Fi rom on my v350awm without a problem. And the beauty of it is, no bloatware.
Again thanks
Google Fi Rom/Kdz
As I posted previously, I successfully restored V350ULM10f_00_NAO_US_OP_0913.kdz to my carrier unlocked V350AWM (AT&T model) using the modded LGUP. Now my thought was that this was the Google Fi rom that comes on the Google version of LG V35. and I know for fact that this rom doesn't have any of the AT&T bloatware that comes on the AT&T LG V35.. When booting I no longer see the AT&T logo, just the LG logo. But the interesting thing is when I check the software version it shows V350AWM10f which seems to say that I really still have the AT&T ROM but the AT&T Bloatware and logo have been stripped out.
Thoughts?

Hi just saw your post and I have an AT&T V35 too so this should help:
1. Uninstall any prior version of LGUP currently installed.
2.Head to Post #18 at https://forum.xda-developers.com/android/general/lg-v35-amazon-project-fi-t3819470/page2
3. Download the ' V35_lgup_modded.zip' ; Unzip & install, then ensure the .dll file is also copied to the COMMON folder (C:\Program Files (x86)\LG Electronics\LGUP\model\common)
-If there's no COMMON folder, create one.
4.Shut down the phone completely(phone should also be unplugged), then get into download mode (With phone off,hold down the UP Volume button and connect the phone to your PC while still holding down the UP button) and release the UP button once you see 'Download Mode' on the display.
5.Now, there's no V35 AT&T Kdz file available online so the next best option is to use the Google-Fi kdz you tried earlier; So launch LGUP & select the Kdz file .
6. Next choose the UPGRADE option and flash.
7. Hopefully, that should bring your phone back to life and if not, try again with the REFURBISH option(will wipe user data etc.)
8.Lastly and very important, though you may be tempted to mess around with additional LGUP options such as PARTITION DL etc.; Remember the V35 is still relatively new & has low support so be careful - So far, cross-flashing seems to be fine except for Korean Kdz files but flashing partitions WILL currently cause you to lose either your IMEI/Serial Number or Both.
Cheers

I just got a chance to try this today and it worked awesome. Thank you! Now I have no bloatware on the phone, and managed to get past a Frp bypass. Now I just need at&t to unlock the device and I will be good to go!

True, after flashing, the software version under 'Settings' does not change to reflect the Google Fi update. This is simply a minor labelling error for now but the important thing is that the update is successful as evidenced by the lack of Carrier bloatware/logo. You can actually verify the fact that you are no longer running an AT&T ROM by trying to update via LG Bridge & it should say there's no available AT&T update.

You are welcome, glad I could help & major thanks to
"metal409" for sharing the modded LGUP in the first place.

I;m gonna have to agree with you as I just installed the latest (just out) version of the Fi Rom, V350ulm10h which can be found here: lg-firmwares.com/downloads-file/17590/V350ULM10h_00_NAO_US_OP_1130.kdz
After installing, my software version is now showing V350awm10h, again indicating that I still have the AT&T Rom.

Hi Yall,
I'm in this same predicament. I've already disabled most of the AT&T Bloatware .... but I'm still super annoyed at the lack of updates (ATT will only let you get OTA updates if you are on their network, my phone is currently unlocked with an unlocked code and on the T-mobile network)
Are there any other benefits to flashing to the Google Fi version other than debloating? Any chance of VOLTE working? or band 71?
Will the annoying carrier branding on the top of the status bar disappear?

Soft brick

I soft bricked the phone and now can only get into download mode. The phone only has two partitions and I was hoping that flashing a KDZ would fix this.
I'm running Linux Mint on my machine and using SALT an LG type open source program in order to flash.
Question: I heard that I should flash something before the Dec 2017 security patch. I can't find any KDZ files unfortunately and was hoping someone here would have a server I could pull it from.

Oh goodness I'm so terribly sorry I seem to have over looked it.
It's an LGV20 H910
What happened is that I used a ROM that was for another model and it kept crashing. After some time I started tinkering with some other software before I realized that even though I bought the device as a 996 I got the 910 version from the eBay seller.
In any case I remember someone mentioning that if I'm going to flash a stock kernel I should stick to something that was before the DEC 2017 security patch so that I can keep the exploit that enables ROM flashing.
Not sure if that's referring to the bootloader that I'll have to flash or the stock ROM itself.
Oh and lastly I remember someone mentioning that the KDZ for my variant of V20 doesn't have any stock images so I'll have to take one from another model flash it to boot then root it and flash a custom bootloader and then re-flash a custom ROM.
That's probably not how it's suppose to work but it's roughly what I remember.

dear what is the condition of your mobile now? does lg up detect the mobile? if so than use LG UP patched version and try to flash your stock kdz.

Sorry darling that it took so long to reply!
My phone is detected by SALT (the open source program developed by steadfasterX) BUT it is doesn't want to work with LGup on a windows system because I don't have the proper .dll to work with my model type.
The LGup log file says
"LGUP can't load the model."
funny enough though the log file shows the model type right after a hex key string.
It says "LG-US996.. US99610d..."
I can get the phone into download mode but the phone doesn't have any partitions right now. So for now it's a paper weight.

every kdz has dll file, even lg up has dll file. you can extract kdz and get dll for your specific model.
use lg up patched version, search on xda, it will solve your problem.
i can not help on linux and SALT, as i dont have these. if you have access to windows machine, than i can try to sort problem for you.
