How To Flash a Demo LG Quantum?

Heya!
I bought a demo LG Quantum for a song today and I've been trying to remove the Demo software by following these instructions:
Through work aquired a Mozart with Telstra Demo(Store) Rom. Very furstrating as it wouldnt hold settings and kept playing that damn video.....
Downloaded this rom (following the links from here and trying a few download mirrors until I found one that worked)
Turned off Phone
Held Volume Down Key while Pressing Power Button (This turns the phone on and launched Bootloader)
Connected to PC Waited about 5 minutes while Windows auto detected the drivers and installed what it needed
Right Mouse clicked on the downloaded Rom and selected "Run as Administrator"
Followed the prompts.
****NOTE**** When it got to 10% the phone rebooted - LET IT!!!!! DO NOT TOUCH IT DO NOT DISCONNECT IT - Just wait -The computer will redetect and about 10 Min later VIOLA - All sorted nice and clean WP7 HTC Mozart (with a with Telstra One Hub - which aint that bad) - Whacked the 3 Sim card in - Downloaded Connection Setup Wizard from market place and a few minutes later was sending and receiving MMS etc

However, I don't know if this applies to the LG Quantum since I can't seem to access the Bootloader screen and the ROM I can't find an executable ROM file like the one he refers to.
Has anyone resolved this problem on their Quantum?
Could you help me through it?
Thanks in advance,
-Aylmer

Nevermind! I was trying to flash it, but, in the LGDP2 Flashing app, I was plugging in the phone before pressing start!
Oups!

If you're still having problems, the other trick is to use the drivers from the LG Mobile Support Tool.

I got mine from eBay for $100...it is a Demo unit. This thread is very helpful and hope to remove the "Device Alive" software and enjoy my nifty windows phone!
As an avid Android and iOS user I look forward to having fun with WP7

How would that trick work?

Does anyone have the link for the stock rom? I can't seem to be able to download from http://depositfiles.com/en/files/tmh1fz1ed. It always says invalid param. Could anyone post it here or upload it to mediafire or something? Thnx

ok managed to download the LG c900 ROM but installing the LGDP2 gives me the Installshield error , Catastrophic Error. And my LG USB Modem doesn't wanna install

Could you give more detail about the problem?
Also, which version of Windows are you using?

I think i bricked my new Samsung S7 edge help please ;_;

So i was rooting my phone with TMWP then my phone was encrypted so i used Odin with an original AP of my samsung device
in the progress of doing that i canceled the progress.
so now i keep getting An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch Pc software. so i did that but now i am at this step, telling me to put the phone in recovery mode but when i try to do that it keeps giving me the same error (An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch Pc software.)
Im freaking out right now if you guys could help PLEASE.

Probably the phone is not detected?
Sent from my SM-G925F

How are you getting to recovery mode?
Should be Vol Down + Home + Power all at the same time
Are you able to power off your device?
If not, press and hold Power + Vol Down until it vibrates or you see it turn completely off, then hold Home (while still holding Power and Vol Down).
Give that a shot to get to recovery.

I had this problem when i tried messing around with TMWP. I dont belive there is one for the S7 egde US models to my knowledge or at least not for att currently due to the us and international models having a different processors International having a Exynos 8890 and US models having a Snapdragon 820. Im pretty sure because of those having different processors TMWP needs to have a build for both processors to my knowledge fix me if im wrong.
Heres what i posted on another thread about trying to flash your phone back to stock and it not working.
Post:
So I would suggest going to this post here and downloading the ODIN 3.12
http://forum.xda-developers.com/showthread.php?t=2711451
I was trying to unroot for a clean root and this one worked for me the one made by PrinceComsy did not work for the flashing the stock ROM but it did work for flashing the ENG Boot ROM. I used 3 out of the 4 file to flash the stock rom I didn't select the BL file at all but you can if you want.
If this help you or you need further/help assistance please feel free to reply to this post

I had the same problem. It is a screen that says something along the lines of 'Update failed' or 'an error occurred during update'. It turned out for me that that actually was recovery mode just with the error screen. Plugging it into Kies on that screen allowed the emergency firmware to work and fix my phone.

Update Failed and Phone Cannot Start. Only Flash Blinks When Charging, NO START/Boot?

I got an update notification. And clicked to update.
When restarted the phone, the phone went to die. I could not start my phone.
I tried these:
1) Kept my fingers on VOL Down and POWER buttons for 2 minutes (even more), but NO USE.
2) Tried to open screws but my screwdrivers could not fit for them.
I bought it 3 months back, but in Flipkat and no service center near me. Any solution for it?

What update did you flash, and what OS were you on?
What device did you have, and was it charged up when you accepted the update?

* I got June update I guess.
* My device is moto g4 plus 1643 model India variant.
* When I connected charger, LED light blinks that was near Fingerprint zone.
* Tried device manager software, it helped nothing.
* Tried to put my fingers on POWER and VOLUME DOWN buttons, but no use.
Really disappointed as it was a gift from my brother.

Just to clarify - you installed the update and then rebooted or just accepted the notification to begin the update (and then rebooted, after which your device failed to boot)?
Did you have TWRP/root and were you on the stock ROM prior to flashing (or a custom stock ROM)?

The update was downloaded, when installing it went blank and never started up.

Did you flash a stock recovery before attempting to update? Having TWRP might be causing the hang; try these suggestions from abhi212b https://forum.xda-developers.com/mo...date-build-t3584982/post72114657#post72114657
Can I ask which custom ROM you were on? You won't be able to flash stock OTA updates with TWRP/customised stock ROM.

My phone is in blank screen. NO start up. No fastboot or recovery mode available. Only light blinks when charger is connected. Then how can I do your suggestions? You didn't understand my problem.

My apologies - I looked through your post history and was wondering if the TWRP/rooting performed previously might have prevented your device from booting.
What is your device detected as when you plug it into your computer, is it Moto G4 or is it Qualcomm HS-USB- 9008 (or similar)?

Right, 2 things to try:
1) Try holding the power button down for 2-3 minutes, this may force a hard restart which might break your device out of whatever state it's in.
2)If 1 doesn't work, you may wish to look into trying a blank-flash (here: https://forum.xda-developers.com/moto-g4-plus/help/solved-unbrick-hard-bricked-dead-t3585016 or here: https://forum.xda-developers.com/showpost.php?p=71405834&postcount=23 ) Depending on what happened with the update, you might be lucky. You may wish to have a look at these blank-flashes too, heed the warning: https://forum.xda-developers.com/showpost.php?p=73151763&postcount=6
3)If 1 and 2 don't work, then unfortunately you'll have to locate a repair centre (or try to find a Motorola service centre) that you could send the device to, or ask Flipkart for assistance. Alternatively, save up for another device. Currently, we don't have another option, though it appears that a member is trying to patch a blankflash for the new update: https://forum.xda-developers.com/showpost.php?p=73152979&postcount=21

I got this when I clicked blankflash:
C:\Users\*****\Downloads\Compressed\blankflash1\blankflash>.\qboot.
exe blank-flash
Motorola qboot utility version 3.40

Press any key to continue . . .

I think, if any one can find new blankflash, I can fix my phone. I think those blankflases are old. I'm on April update, and failed when I tried for June update.

Samsung Galaxy Tab A(10.1 2019) SM-T510 soft-brick

Hey guys,
im sorry if the topic doesnt fit here. I am new and not a techi. My Son just tried to flash some custom ROM on our Samsung Tab A and somehow bricked it. It is not possible for me to get into Recovery or Download Mode i have already tried all Button-Combinations. It just shows an error saying "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I have already tried with draining the Baterry empty (described in forum thread here: https://forum.xda-developers.com/showthread.php?t=1478361) and plug it in to get the Charging symbol. But it doesnt happen. It just shows only the Error..
So i really dont have any more ideas how to get into recovery/download mode.. Is there anything i didnt tried??
It seems like the download-mode is not available. Is there a way to "install" a new one??
edit: it seems like this IS the download-mode.. anyways i think i just need the stock firmware for this model T510NZKDDBT. I cant find it via duckduck/google..
Maybe someone can help me with it?
Thank you

nevermind!! i've figured it out. Flashed new bootloader via Odin. Now its working again
Thread can be closed!

I know I'm a year late, and you've either figured this out or moved on, but maybe I can clear this up for anyone else in the same situation.
I stuffed up and got the same message - "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
That error message screen is basically the download screen. Windows (and the Smart Switch software) won't connect to the tablet while that screen is displayed, but Odin will.
You can bring up Odin and re-flash the stock software (or whatever you need) while that message is displayed. If you still have trouble, holding power and down-volume will re-initialise the download screen, though it will still display the same "emergency recovery function" error message.
I hope that's enough of a description to get people out of trouble!

Wrong firmware.

I had my original SM-J510MN bricked last night because I tried to install a corrupt or incompatible TWRP image on it, so, in the way all through the hell I did the following:
1. There is no information on Google about this exact machine (MSM8960).
2. I messed up with SmartSwitch PC Software piece of junk by reinstalling the driver which never worked, provided by its own SmartSwitch option menu.
3. That driver installed before was never going to work because you have to boot Windows 7 in a way to avoid signed drivers checking (Pressing F8 at boot).
4. After research I found out that I had to downgrade the SmartSwitch version to a one with the enabled tab "Device initialization".
5. Finally, I had the driver and a correct SmartSwitch version just to realize I had to type the Model name of my device in UPPERCASE because those Samsung engineers didn't realize a normal user may be would type in lowercase ().
6. I typed the S/N (serial number) located on the backside of the phone and I got the message "Please check the model name and S/N, and enter them again". I triple checked the inserted values, to this point I was feeling I'm totally lost.
7. I downloaded at least 10 Gibibytes (Gigabytes but in the right terms) in stock ROMs which none of them worked for multiple and different reasons.
So this beautiful COVID-19 lockdown morning I woke up inspired thanks Jehovah God and I just tried the old way to inspect this whole site by using Google like this: "site:xda-developers.com j510mn" and I found a compatible fully working TWRP that I flashed using Odin v3.14.1 and then the phone booted normally.
While I was looking for a custom ROM then I didn't realize the WiFi stopped working so I am looking for a solution.
2020-06-06
To bring the Wi-Fi back to my device I had to flash LineageOS 14.1, and then you will be able to flash any custom ROM you may find.
I hope this helps, greetings from Colombia.

When you open your device hold power button + Down volume + home button and flash the stock ROM, its a soft brick, not hard brick. J510MN is fully compatible with every version of TWRP.

OK, sorry for not having been that explicit, but I'm going to be right now:
Last night I had a useless phone...
satisfied?
does your correction help in any way? does that help with the initial post at all? is there any difference between hard and soft bricked that could help on that?
