Someone please help!
I have a LG Optimus L7 P705g, on v10C stock rom, rooted according to http://forum.xda-developers.com/showthread.php?t=1906133
Then I tried to unlock bootloader and install cwm recovery following http://forum.xda-developers.com/showthread.php?t=1664322
I tried both v1 and v2 of the L7CWM archive. But the phone keeps rebooting about 2 minutes after power on.
No matter I boot normally, or boot into cwm recovery, it still restarts about 2 minutes in.
It's driving me crazy. Can somebody give me some pointer in how to resolve this constant reboot situation?
I believe I followed all the instructions provided with the above threads, and tried flashing both v1 and v2 a few times.
Thanks in advance!

ok, you need to do this.
First, follow this tutorial http://forum.xda-developers.com/showpost.php?p=31828740&postcount=1191 to flash the ROM from this post http://forum.xda-developers.com/showthread.php?t=2176430 this rom is already rooted, and includes CWM and unlocked bootloader, so you shouldn't have any problems to flash any other ROM after that one.
and second, you need to learn to search on the forum, and read more before asking already solved issues.
good luck

Thanks for your quick reply! Actually, I'm a little hesitant to use kdz updater, as I've read some posts saying that even after they flash the stock kdz, the phone was in an even worse situation.
Since I can still boot into cwm recovery (I have a 2-minute time frame before the phone restarts itself), should I do a wipe cache or something? Will it help?
Flashing the whole thing is my last resort.

yes, I've also read that some people have problems after flashin kdz....but i dont know why, KDZ flashing is usually the best way to make sure your phone is back to a "perfect" working state, since it restores everything to the way it should be, and in most situations is the only way to unbrick the phone.
I can't tell you how many times I had to use KDZ updater to restore my phone after messing with it, im not a developer but i do a lot of experiments with my phone trying to make it work better, and most of the times it end totally bricked, and every time KDZ updater saves my ass. Some time ago i was trying to modify the stock rom myself, and I used to flash via KDZ my phone at least twice a day....so for me is pretty safe to use

I tried to read as many posts as possible about using the L7CWM archive to unlock bootloader and CWM recovery before actually doing it. People with P700 and P705 both reported success. I don't know what I did wrong. I am so frustrated...
The ROM you pointed me to get is for P700, does it matter? (Mine is P705). Or should I use my stock rom kdz to test it out first?
Also the two links that you gave me have different phone mode setting in the KDZ updater, one set as EMERGENCY, the other one set as DIAG. Which one should I use?
Thanks again!
Hope there is an easier way than using the KDZ updater... :fingers-crossed:

yep, it's for P700, but other than NFC, there's no difference...i dont recomend to use that rom for every day because it will drain your battery because of the NFC. but since it comes already rooted and unlocked, its an excelent base to make sure everything is well installed, after that you should be able to enter into recovery without problems, and then you can flash a ROM for P705. Personally I suggest you to try this one http://forum.xda-developers.com/showthread.php?t=2472479 it's working very good for me, and have specific kernel to p705
Of course you can try with stock kdz for p705, but hen you will have to repeat the process with L7CWM and chances are that something goes wrong again.
And I gave you the link that use EMERGENCY because it is the way I use to flash a KDZ, you can try to follow tutorial with DIAG option, but I haven't test it myself, and I would never recommend something I haven't tested before. Also because you said your phone reboots every two minutes, and I think DIAG option needs the phone to be ON while flashing, in EMERGENCY option, the phone will never turn off untill you unplug the cable.

I read another post about flashing the Homero's v10K rooted KDZ that you mentioned into a North American P705, and that made the phone unbootable.
But fortunately, I managed to get a stock bootloader from a friend's North American P705 and push it into my phone. This did the trick, my phone didn't have the boot loop anymore.
Then, I upgraded the stock firmware to v20A via LG's mobile support tool. At this version (JB as opposed to ICS), I tried to push the cracked bootloader into the phone again. This time, everything was all right, no boot loop! So I flashed the CWM recovery, and everything was good.
I just tested out Szymel's modded stock rom v20E with OC 1305Mhz, seems pretty good!
Now I have a lot of ROM choices to test out. :laugh:
Anyway, thanks so much for your help and suggestions!

Hi, i had the same 3 days before just set it in downloadmode and use the official lg support tool to restore!!!!
Hello
I have LG G2 32GB from HK
First I Rooted the device, everything was OK- phone works...
Than I decided to burn STOCK ROM , i used LG Flash Tool 2014
Flash was 100% success, no error
After Device finish boot,
In the first Welcome screen (where you choose language)
I cannot touch the screen, everywhere i click (touch) the screen it seems like i touch somewhere else....
I cannot proceed forward from the welcome screen
The phone does not respond to my touch.... broken
The phone goes into Download mode, and quite strange- though i flah unrooted Stock Rom - it still writes that the phone is rooted.....
I tried to flash 5 different ROM (kdz file), None of them helped...same problem for each KDZ
I tried to flash using Win 8.1 , and Win7 ...same thing..touch not working after boot finished.....
I found a similart problem with no solution:

You have a refurb and a different model. Check my post here. You need to open your phone, you either have the D800 or D801. Flash that ROM, and you wil be fine.

I think i'm having exactly the same problem as you T_T
so i decided to open my LG G2 to find out which exact model it is, and what i found is LS980 instead of D802.
but when i try to flash it with .tot files with LG flashtool v1.81, but i always got [Download FAIL!!] Check DLL or BIN file.
i also tried to flash it with some KDZ files like (D80210B_00, D80210F_00) i got 100% success but stuck at 1st welcome screen too.
i tried to look for KDZ file for the LS980 version but i can't any, so can someone please help me out here, please?
Would it work if i flash it with KDZ if i can find the LS980 KDZ-file for it?
i hope someone can help me please...
i attached 2pics below and sorry for my bad english.

You can flash with the TOT, you just need to edit the TOT file in a Hex editor and change the model to what you have (LS980). Look at my post here on how to do that.

are you able to get into recovery?
if yes you can flash stock ROM which can be found in the xda thread
I'm experiencing an identical issue with my G2 (T-Mobile). In attempt to install CM 13, it failed and left me with no recovery, download, or fastboot modes.
Please help me! I'm desperate to get my phone back.
