Hi all,
i have a problem, got a new Lg L7 P710, and i wanted to jailbreak/root etc. but i think i failed with it.
also i tried with KDZ updater, and installing LG modem and Lg Androidnet usb serial port (com6)/ and installed all those drivers needed. My SD card is still in the phone, but i can't see it in ''my Computer'' when my LG is plugged into mine laptop.. also the rooting part its failing.. btw my yellow screen for emergency is not normal, its kinda with stripes, and i can't see the ''emergency' 'word on the phone when it is yellow, sometimes it goes blue screen with stripes...
i don't think its a hardware problem, but i accidently deleted everything also in SD card, and in the phone self, its just like a Stock peg...and also i lost my warranty in 3 weeks -_-'', i can't do anything, only plugg it in mine laptop, and i hear a noise sometimes, dat it is plugged in, but only in ''Device manager'' I also read some other forums, with bricked or unbricked, or ADB ( also tried with this and CMD) but didnot recognise mine phone... as you can see, my phone is connected to mine laptop ( see pictures)
any solutions/help please? :crying:

Hi guys, can anyone help me with this, I recently acquired a lg e400 and rooted it, was going to flash cyanogenmod for it but i messed up and flashed a different baseband for a different model phone first(i know it was stupid, now i have a semi-hard brick and the only mode i can get into is a black screen, computer sees the phone as lge androidnet usb, i enter this by holding the vol down and power as i plug into the computer. I've tried every other key combo but cannot get into any other mode....i've tried using the lg flash tool with no success, tried uptest with no result, tried the lg mobile support tool and it picks up my phone as the correct phone lge400r with a software version of v20e which used to be a v10b....how can i flash just the correct baseband?....i also tried kdz and when i try and flash the original kdz file it starts but fails with wparam:100 lparam:1002, i'm thinking maybe i have the incorrect firmware kdz....could anyone point me in the right direction with this?....it's driving me nuts

I think that you should use this site LINK. There you have all of the firmwares for L3, and you can choose baseband

yes, i tried that, but the only mode i can enter is download mode.....kdz updater fails, is there a way to flash in download mode?
1. Download THIS, your firmware as .kdz file and LG PC Suite
2. Install msxml.msi, and LG PC Suite
3. Run KDZ_FW_UPD (some antivirus software can recognize it as malicious software, but I have used it, and there is not any problem with this)
4. Select Type: 3GQCT, PhoneMode: DIAG or PhoneMode: Emergency (I don't know what is difference between them, so you have to test it)
5. In KDZ File you are choosing your previously downloaded firmware which is in .kdz format file
6. Boot to Download Mode (vol down + power) in the same moment you have to plug your LG to PC.
7. Wait for drivers installation, if nothing is installing go to the next step.
8. In KDZ_FW_UPD hit Launch Software Update and you have to wait until you see message "===FINISHED==="
That's all.
I used THIS guide.
Hello XDA-Community
Today i accidently briked my G2 (D802 KitKat 4.4.2). I was flashing it because i wanted to unroot it but during the process an error showed up and my phone was dead.
So i tried to fix it with this method http://forum.xda-developers.com/showthread.php?p=48765620#post48765620 but it didn't worked as planned.
Now i have an G2 which is stuck in a bootloop and i can't even reach the recovery or the download mode and i don't have any custom recovery installed.
Anyone who can help me with this get's an 10€/$ PSC. I can't give more because i dont have any money left (16 years old).
Big thanks to everyone who can help me with this
PS: Sorry for my bad english i'm not a native speaker
While you wait for an answer make sure your phone is kept charged.
Have you tried LG flashtool and your stock ROM?
make sure it's off, hold the VOLUME UP button while plugging it into your computer, and that should get it into download mode.
Next try using the TOT method (google it) and voila!
Yeah the problem is that i can't even reach the download mode and my computer doesn't recognize my phone it's just an qshub device. ;(
I had the same issue bricking my lg g2 and i was stuck with the logo and nothing more not even download mode,recovery etc...
The way i got it to stock was i installed the lg g2 drivers and from there on just flashed it with flashtools kdz and got it workking again i think this shoould help you out just plug your phone and install the drivers and use flashtools
Install this driver then report me back or cap screen device manager to me.I will help you for fee.

Please Help me somebody ... i cant afford to buy new phone i just bought this phone a week ago ..
Having same issue ! XDA forum experts always helped me with every situation with my phones. Expecting help this time as well from you experts.
Same here, enyone can help, i stuck with the sam message, presing vol- just rebots, and vol+ sends message "jump to download mode" but i cant flash stock firmware
i have the same problem any help ??
I have the same issue too, can anyone help?
I heard that this can help you guys. Use the search option there and try to fix it. Actually i had the same problem few months ago, but for me mew motherboard was the solution... If you're device is under warranty send it saying it failed while taking OTA. Good luck...
lg g2 critical error
I have done a flash to my g2 32gb d802 and it suddenly entered into critical error not going into any of thefastboot mode or download mode even though it is giving me options.....please any one help me out to get my phone back to normal ........
PM me if you guys need help.
I had the exactly same problem, and I had to go to afterservice center to repair. Engineer told he would wipe everything and install new rom. but He failed to write rom so he simply changed mainboard.
At first I had thought about open my g2 and makes it go into qualcomm download mode by short-circuit.
the reason I didn't was my warranty was still available.
I tried every method to make it boot into recovery or download mode but I failed. In my opinion, you may try short-circuit method for last solution. In this situation, even linux doesn't mount rom's storage section. Only if you can make G2 recognized in Linux, G2 will revive.
good luck.

The best way to go if you do not have a warranty is to short circuit the board and get into Qualcomm ... 9006 mode. However, when you get the demigod error plug in you usb and click up and it should start download mode even though it doesn't show it.

How do you short the pins? There's a guide here on xda but it's so difficult to undestand. I need to know how can I short the pins.
it should start download mode even though it doesn't show it.

No, it doesn't. I try to use flashtool but it doesn't recognize the phone. No download mode in any method I tried
I got into this error after I had previously recovered into qhs_usb9006_bulk mode from a hard bricked D801, by shorting the capacitors on the main board. After entering qhs_usb9006, I used srk tools 2.1 for my phone, and after they finished, I tried entering download mode, only to get into this error. I really don't know what it is to say about this. Everything turned wrong with this phone, it went from simply failing a .kdz, to stock .tot, to hard brick, and now to this error, whereas it should've just enter the download mode, as for the 99,99% of the others. Any help would be really appreciated. Thanks.
L.E. I shorted the capacitors again (the one i the middle, like I did the first time, when i got into 9006 mode. 5000 and 5004 didn't work for some reason). This time I got into dload mode, which is 9008. I'll try to recover the phone from here, with this method:

i had this problem while trying to return to stock. Fixed it by following this guide http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 . it needs some hardware tampering though. i tried and tried but i cant flash the phone any other way. the way i understand this is due to bootloader being corrupt.
I installed autorec from playstore solved all the problems
Than you! autorec worked for me too
Can someone post a KK baseband for D801 (T-Mobile)? I'm on D80120a software version with unknown IMEI and baseband (the phone is a D801 refurbished into D802, I more than hardbricked it by flashing wrong .kdz, got it recovered through shorting pins, 9008 mode, got download mode, D80120a stock, root, twrp, after a very long and painful process of about 1 month). Now I have to make use of QPST, but I have to obtain a valid baseband first. Of all links I've stumbled upon, only 5% or less of them are still working, so I only have one flashable modem, in twrp recovery, which corresponds to D801 jb version.
http://downloads.codefi.re/autoprime/LG/LG_G2/G2_modems
cloudyfa kk_baseband_D801 only make my phone restarts like crazy.
I'm simply stuck and pray for some devine help.
Thank you.
Weird enough, I flashed a canadian modem and I got both baseband and IMEI. Why did I do that in the first place? Because I remembered that before all these things happened to my phone, the baseband was M8974A-AAAANAZM-1.0.190082, which corresponds to D803. So I said to myself what can happen by flashing the wrong modem? Boot loop, easily fixable with the phone in it's current state. But again, after 1 month of trouble with the phone, I'm back to what exactly started it in the first place: phone seem to work OK but it has 2 huge problems: WiFi extremely weak (2 meters away and a wall or 5 meters away and no wall a and I lose the signal in both cases; the 2nd is wit the GPS - 20-30 meters error). No idea how should I adapt the radio to Europe region (by keeping the canadian one and change the settings, if it's even possible/fixable this way or if this even does make any sense).
I had to do a hard brick fix to get it into the QSUSB mode to flash TOT.
