Unbricking your LG Optimus Regard

So while tinkering with my phone, the LG optimus Regard, I bricked it. Then I found a rom for the LG Motion MS-770 witch works with my phone, however after flashing this rom, my phone is now on MetroPCS. I need to know how to get my phone back on cricket (NO ROMS AVALIBLE FOR THE LG OPTIMUS REGARD, ANYWHERE) so how do I hack my carrier back to cricket.
Also does anyone know how I can change my Model number back to LW-770 as opposed to MS-770
Thanks in advance, please anyone help me as I am without a phone until someone replies.
Issue Solved​Follow these instructions to Unbrick your LG Optimus Regard​Or switch your carrier back to cricket​For all those encountering similar issues, or those in need of the stock firmware for the LG Optimus regard (LW-770) use this website: http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxx Where xxxx should be your IMEI, it will lead you to a text page with unclickable hyperlinks that you should copy and paste into your browser. I have not tried the global version. DO NOT CHANGE ESN TO IMEI it is not neccisary and will lead you to a blank page. Use, UpTestEX_mod2_marwin.exe to convert the .cab file to .kdv and use KDZ_FW_UPD.exe to flash it. If you need those files, they come together in a .zip file titled KDZ_FW_UPD_EN a quick google search will return proper results. In order for the above steps to work, you have to put your Regard into Download mode (Full power down, then while powering up, hold Vol Up, Vol Down & Power).
Full credit for finding the rom goes to Vosetal, I spent all day crawling the csmg.lgmobile.com and could not for the life of me figure out how to search my ESN as it is entirely inaccessible, and no FTP access permitted.
Hope this guide helps you unbrick your phone
I will update the language and the linguistics of this guide when I havent been up all night.

You already have a thread open - please do not open another one for the same thing. Reported.

Ok Simon, sorry, Its just I wanted a different title as my previous thread was asking for the rom for my phone. Since no one has it, I am contempt with this rom from the other carrier. As thus my request has changed, now I want instructions for changing my carrier to Cricket.
Please Admin, erase my previous threat not this one, as this one is more relevant.

ATT LG Optimus e970 brick need fix :(

My LG e970 got brick by using ROM manager. I went into recovery mode and it stucks on LG logo.
It is going in Download Mode but dont know its purpose.
I have search the forum it says use LGNPST. now i have LGNPST and also Stock rom.
Getting the Model error. May be i have the wrong dll file. its LGNPST_LS970.dll dnt whether it is the right file or not.
Please provide solution to revive my mobile .
Thanks in advance.
I dnt remember the IMEI number nor do I have the mobile box. Stuck with a Brick.

I am not too familiar with that model, but your IMEI should be under the battery. Should be a sticker. There is most likely a newer dll file you can use and make sure that you are using a USB 2.0 port. Some users said somewhere that they has issues on a 3.0 port.

Lg G4 hard brick... need help please wiling to donate cash.

Hi everybody..
I'm in desperate need of help. After attempting to root my g4 somehow something went wrong and the phone is completely dead with no sign of life . I know there isn't a way yet to unbrick the g4 but I'm hoping somebody out there is working on it and maybe can help me out.. I'm willing to donate for the help Thank you !

What exactly are your symptoms? Does it not even turn on? Have you tried getting into download mode? How exactly did you try to root it? What were your steps and are you able to identify where you went wrong exactly?

I was trying to gain root access following this method : http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765. everything seemed to go well but after it was complete the phone wouldn't start and it booted only to a message on the LG LOGO with something failed. At that point I was still able to get to download mood so I tried to restore it to stock doing this : http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848. again the process went like it should but at the end the phone went dead with no signs of life, No led light, No vibration, can't turn on to anything and only gets detected on the computer as " qhsusb bulk ". My guess is I used the wrong KDZ files
I would appreciate it if you can help.

It indeed sounds like you have a hard brick, in which case the device can't be brought back to life.
However for chance, and for future reference. Which kdz did you try to flash? Assuming your device is the ATT model, then did you download the Puerto Rico kdz?
Because there is not a KDZ or TOT for the ATT H810 model the Puerto Rico KDZ from Claro will recover an ATT soft brick. These are labeled H810PR.

Maybe you downloaded the wrong img file from the first post? It has to not only match your phone, but ALSO match the version of the firmware you're currently running. That's why this method here is better:
http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
Because you just make a backup img of your system partition and then inject root into that and you have a new rooted system partition img file along with your original system partition image file so you can go back to stock if you want some time later. I'm guessing you tried flashing the wrong version of your firmware. Do you know what version you were on? Looks like the only one listed on that thread is version g. I'm on version b, so if I were to have tried that, I would also have had an error when trying to boot. Had you made a backup of your original system partition as mentioned here you should have simply been able to dd it back and you'd be up and running. However now it looks like you've "hard bricked" your phone indeed. Out of curiosity, which KDZ file did you use? What's the file name that downloaded?
It looks like there are some utilities created that can UNBRICK some phones when they get into this state, but it looks like they have had custom scripts written for the partitions of those phones, for example:
https://www.youtube.com/watch?v=ERZvlJIC9dE
https://forums.oneplus.net/threads/solution-recover-from-hard-bricked-oneplus-one.104943/
Maybe someone familiar with how those apps run could modify that app for unbricking the G4s? Currently however, there doesn't seem to be anything you can currently do to immediately fix your phone. So ... can you get it exchanged or replaced????

Honestly, bring the phone to ATT and tell them it said an update was available, and upon accepting it...the phone ended up in this state. They will most likely exchange it for you.

not an option because I bought it from somebody on craigslist... I already bought another one so I'll just wait and see if somebody comes up with a solution if not I'll sell it for parts.

Any chance they can give you the original receipt and that way you could possibly send it in for warranty work.

LG G2 D802 with different model parts (most definitely refurbished ) Soft bricked !!

So a few years back i bought an unlocked LG G2 D802 phone from a local retailer. I have always been a Samsung user and never used it and forgot about it. Until recently i remembered about it and as it was out of warranty i decided i should root it and put some custom ROM on it. I rooted it and flashed a custom ROM . But it got stuck on the LG logo at the boot screen. i didn't think of anything at that moment at all. As getting a boot loop is a very common thing in Samsung devices as well and decided i should just stick with a Stock 5.0.2 ROM.
After flashing the stock 5.0.2 i noticed that i lost my imei, baseband etc, and i had forgot to make a backup of the EFS. So now i got suspicious of the phone not being a D802 . i opened it up and sure enough the antenna module had D801/D803 written on it, i proceeded and found the LCD digitizer had D800 written on it and the motherboard had D801 written on it. Now i'm stuck with a useless phone which doesn't have any imei and baseband, i cannot click on the build options to even enable USB debugging mode and i'm not sure of the model.
I should add here that now if i try to flash a stock ROM for d801 with the kdz method i get an error saying i should retry. if i do it with the .tot method it says the device model is d802, which it is not at all. I used the buildprop app and edited the device model to D801 and tried the .tot method again. This time it gave me an error saying that laf.img has been moved and gets stuck in the download mode. I really cannot understand what to do !! please somebody help !

Fake ALIEXpress H901 that was H900? Bricked after H901 update and worked with H900.

I bought a V10 H901 in Aliexpress and the IMEI sayd that was a H901BK. It was with the T-Mobile software and Android 6 MM. In PC it said the H90121j and I wanted to upgrade to 7 Nougat and I put the phone in the PC and after the update with LG Bridge it just bricked. Died and do not back to life. I unbreacked my phone with this tutorial:
https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
The Unbrick H901 SD card didn't work, but this worked.
After that, I tried to install all H901 firmwares and didn't work. So I decided to install the H900 firmware and the phone finelly worked. It's working everything fine with no malfunction. Just the Android back to 6 MM, but with the AT&T apps.
I didn't understand nothing. My phone was a fake H901, because is a Refurbished phone. I'd like to install the Nougat update. Is it possible?

Just check at&t website= https://www.att.com/devicehowto/tut...bystep_KM1134561?make=LG&model=LGH900&gsi=oyB
at&t is just behind as always with updates. The other carriers like Verizon, T-mobile etc just push the updates to the devices without sim card or other crap steps

I have same exact problem with same refurbished phone h90121j I unbricked with the same method but I cant install AT&T software because LGUP says that I can't go from H901 to H900. I can flash any other H901BM firmware but my phone bricks again and again.

You'll probabilly need an Octopus box to reinstall the firmware. Try to find someone who can help you with that.

Yes. I have used this method to unbrick from 9008 mode and get download mode https://forum.xda-developers.com/att-lg-v10/help/lg-h900-unbrick-via-qfil-t3739309
Then extracted dz from AT&T H90021w.kdz using LGExtract.exe
And then flashed dz to phone via LGUP.
It's strange but AT&T firmware is only one that working in this case. On my phone without any bugs, fingerprint working, can install apps from play store etc. Only downside is that you will be stuck on Android Marshmallow but at least you'll get working phone.

Probably this method wont work on korean models without bugs. Not sure about kdz and dz. You can try.

Thank you so much!! I tried for a long time to restore the phone, finally the phone works, YOU ARE DIRECTLY HERO))
