[Q] Sprint LG G2 Bricked by Custom Recovery

Sorry to bother everyone, but I am in a really sticky situation here. I don't know much about rooting and recovery, and have run into a real issue, so I will try to explain as best I can. I rooted my phone no problem and installed a custom recovery that didn't work at all, so I left it and forgot about it. Today, I tried to update my phone but when it rebooted I simply got the message: [830] Fastboot mode started then below it says: [830]udc_start() and will not advance. I cannot do anything with the phone when I plug it in nor can I access any of the files aw it doesn't seem to be recognized, and when I boot into recovery I just get the screen with the same message. I tried putting it into download mode, but it just said 0% and no messages about drivers or anything popped up onto my screen. I am in a real pinch here fellas, and I really hope you guys can help me out. Thank you all in advance.

I can't boot into recovery though, which every guide I find has me do, and putting it into download mode doesn't work. It isn't recognized on my computer either.

You have to read carefully.. Do as it says.. It works.. You have to download the right drivers and then get it in download mode and then flash stock rom... I don't have the time to tell you every step but that's what needs to be done

Here's the link.. That's all I got time for.http://forum.xda-developers.com/showthread.php?t=2432476

Here are a few screenshots that can help you guys identify the issue. First is a screenshot of the lg support tool, which recognizes my phone as a "testmodel"
The next is an image of what happens when I try to upgrade recovery.
Also, the lg mobile support tool doesn't even have the ls980 drivers. Can anyone give me instructions on where to go from here?

You have the wrong files.. Make sure you download the files for your phone.. Their are many models. That's why its failing.. Read everything before you take action.

Thank you everyone, the issue was fixed! After verifying the files, looks like I picked up the wrong TOT file. Had so many of them downloaded over trying to fix this I confused them . Thank you for all of the help, I truly appreciate it. I'm not sure if I am supposed to close the thread or if a moderator will do it or what the protocol is, but consider the issue resolved .

You should move this to the Q & A section. Nobody is going to help you here because this section is reserved for actual development. Just trying to help keep you from getting flamed...

I had my phone stuck in TWRP twice last night from failed Rom flashing. This is my post in another thread on how I fixed it. Try this to see if it helps, I'm not responsible if you do any more damage

ADB Sideload. Respond if you need help with it. Macs are the easiest for ADB sideloading because they don't need drivers, I could help you with a PC too but it's more annoying.

The issue with Linux is there aren't any official Google ports for the files for ADB Sideloading. Do you have access to a PC or a Mac? http://developer.android.com/sdk/index.html these are the Android SDK files for Mac and Windows, I'm not quite sure if they have Linux support, but you could try. Also Wine, the program that allows you to run Windows apps on Linux or Mac will not work with this because of the way it works, so you need an actual Windows or Mac device. However, if it does support Linux I'm sure it wouldn't be any harder than it is on Windows or Mac. Also I tried using the LG Flash Tool method on various devices and it was more complicated and wouldn't work for me for whatever reason even after installing the drivers.

how would you sideload from a mac. mines stuck. in twrp i didnt even know the radio was updating. i guess my daughter pressed it. lol she was using quick memo to color. what files would i need? i tried to do all the other ways on my wifes windows pc but no go. the phone tries to update firmware when i plug it in and stays at 0.

I'll just say that the way I did it in my post worked for me twice while I was stuck in a TWRP boot loop from failed ROM flashing. Both times it worked with out a hitch to get my Sprint g2 running a tmobile rom back to stock Sprint.

A you running the newest TWRP? I know I wasn't and it continued to fail and stick me in the boot loop into TWRP. Once I updated, I was able to flash CM11 and it's working perfect.

Can u please tell me how you rooted your lg leon cause i wanna root it too but i cant find any way

Hello,
The following should work:
1) turn of the phone completely
2) do hard reset ( http://www.recovery-mode.com/android/lg-leon-4g-lte-h340n.html )
The phone will be reset to like when you bought him. This means you will lose every app etc. but at least he will work again

hm that's weird.. anyway let's try it another way then
1. Download Super-Root.apk for LG Leon from this link : Download or http://downloadsafe.org/file/0yF980
2. Connect your device to your PC using the USB cable.
3. Copy the Super-Root.apk over to the root of your SD card.
4. Once it’s been copied, disconnect your device from your PC.
5. Head to Menu>>Settings>>Security on your device and enable the Unknown sources option.
6. Open the File Manager app on your device and install the app you copied earlier to your device.
7. Once the app’s been installed, launch it from your App Drawer.
8. Select Install SuperSU from the first dropdown menu.
9. Select exploit, tap on it in the app.
10. The app should begin rooting your device, shouldn’t take too long to finish.
11. Reboot your device once it’s been rooted.
12. You’re all done! Excellent! You’ve successfully rooted your Android device using the Super-Root.apk app and you should now be able to see the SuperSU app in your App Drawer!

Well i try kingoroot for my LG LEON H340C and worked try it too!

kingo bricked me... king root and then SUPER SU ME worked for me

Phone bricked while rooting

So i used this guide to root my phone:
youtube. com/watch?v=AMNVruAU6do
at the end it doesnt installed spuerSU and my phone have bootloop.
then i thought maybe factory reset would help. So i did it, and now i cant acces to my phone at all.
any thoughts?

Ok, need more info,
What model GRA ???
What Build No. ?
What you have tried since?
If the phone was bootlooping how did you access "factory re-set" ?
Have you done ANY searching/reading to help yourself, not least, even my advice in the post below "P8 Stuck at Boot"?
Have you any experience in flashing this phone or even others?

model GRA-l09
Build emui 4.03
so i used SRKToolHuawei 2.0 and it installed TWRP.
then i rooted, and it went into bootloop. So by this program i enterd TWPR again and did factory reset.
and i tried to reload lastest patch but i got "waiting for device", and its not moving from there.
only used kingroot to root another phone. and i tried looking on other forums for solution but nothing helped.

Have you tried downloading an official ROM, say B999, and putting the "update.app" into a folder on SD card named Dload and rebooting while holding all three buttons?
Have you read my advice here? :-
https://forum.xda-developers.com/huawei-p8/help/huawei-p8-l09-bootloop-trying-to-root-t3695022

ohhhh i will try this option, but first need to get another phone so i can put things on sd card ;/

okey it worked and put me into TWRP mode. What i should do next? continue to root?

So i continued to root installed supersu and now my phone is working, but still i dont have root, and i cant find super su app. Anyway thx for help <3

@krullol
If using B399 you MUST use the latest versions of TWRP and SU.
Just follow the instructions in post #1,
https://forum.xda-developers.com/hua...4-0-1-t3431249
TO THE LETTER, using these linked to files (TWRP and SuperSU) and, hey presto, a fully rooted P8.

TB-X704F, Trying to restore stock

Hey all,
I am trying to restore stock onto my TB-X704F but am struggling. I downloaded the QPST flashing software, the stock rom and lenovo usb drivers. However in the qfil app I cannot get my tablet to register, the program doesn't register any connected devices.
Has anyone done this before or know where I am going wrong?
Lisa

Same here.
I can't flash it at all. I get an error in sahara. USED QFIL though. I don't have .hex for QPST.
To get COM working you need:
adb devices
adb reboot edl

Use the Rescue and Smart Assistant (LMSA) from Lenovo. That's the easiest option.

Hi, how did you do it ?
I'm having the same problem after a failed flash attempt of LineageOS 18. Used lenovo LMSA to restore it and went through reflashing to stock but i cant get past the initial steps of setting the device up as it reboots.
