or if do not work for you... install it again but not with SmartFlash. I know that is easier but often give this error. I suffer 2 times with it. use LG Flash tool...I know I know... is more complicated but there is nice tutorial that you will find easy in the forum
Good luck.

I see then i guess im not that lucky. I had twrp (a previous version) already and when i try to flash the newest one in fastboot there is no diff. i tried flashing CWM instead and still no dice. I used the all in one tool (idk if it makes a difference or not)

Help, problems with booting LG P920

Hello, I have a LG P920. When I was going to root it and install an ICS rom I tried to install the u-boot and x-loader from wkpark. But for som reason the phone wouldn't boot, so it got stuck in a bootloop. After trying to fix it several ways i ended up with it boot directly into recovery and when I try to flash a boot.img it says that it doesn't excist any boot partiton. I have really no idea what to do to fix it. Please help. In advance thank you.
Did you try flash *.bin or *.kdz ??
And what you mean with "when I try to flash boot.img ..." the recovery can not flash a *.img
Just *.zip which contain :- boot.img and META-INF .
Here is the link :-
http://forum.xda-developers.com/showthread.php?t=1629307
Yeah, try flashing with lg flashtool

When I said flash boot.img I meant trough fastboot, followed this tutorial. And for some reason I cannot access recovery, it is highly possible that I am doing that the wrong way.
I have tried to use LG Flasht tools, but I think I'm doing something wrong. And when thats said, I'm not completly sure in which mode I should be in, meaning fastboot, recovery, download mode. The problem is that when I try using flash tools, it seems when I set it to use port 1 in flash tools nothing happends. When comparing to other screenshots, I can also see that in flash tools it doesn't recognise, or at least not telling me (at the top info bar) what model, or S/W just the file name.
I kind of tried smart flash from the link, but I ended up with a complete wipe, and it seemed like it hadn't been flashed any new rom.
About the mode just remove sim , sd card and the battery press and hold vol up and then connect it to the computer .
About the port , first you should change the port from windows device manager to port 1 .
I'm sorry about the boot.img ...etc . So I see many people in XDA extract the *.zip and flash it with CWM . In XDA I saw every thing

Hey this happened to me yesterday

I have the same problem. I tried all ways to solve but they didn't work.
I flashed ICS Rom for my P920 from xbsall, but I had some problems about signal. The calls are always disconnected while Wifi 3G work normally.
I decided to flash v21.e ROM ( GB) again but the phone just stuck at Logo LG (I tried both kdz or bin file). Seems to be hopeless :crying:. I also realize that the Emergency mode disappeared ( The screen just flashed fast and off ).
The problem is solved if I flash ICS ROM back, but I don't want to.
Need help from you guys !

just use xbsall repair method
I have fixed the phone. After doing a lot of what I don't know what I do. I finally realised that one of my biggest problems was that I used a 64 bit windows 7 computer. The way I fixed mine was trough setting it in normal download mode and you smart flash to get it to an original rom. If anybody need to try what I did and need help from me, if I can provide it. You should send a PM because I am never in the LG P920 thread beacuse I was fixing a friends phone. So as for me this thread can be closed moderators.

[Q] ?HowTo? P720 from CM10 back to StockROM

Is there any working way, to flash my LG P720 back from CM10 to StockROM?
I have tried different ways:
- flash with KDZ_FW_UPD.exe
- flash with UpTestEX_mod2_marwin.exe
- flash with the the LGMobile Support-Tool
I have tried this:
http://forum.xda-developers.com/showthread.php?t=1287236
I have read a lot, but I found no answer... .
What works..
- go to fastboot 0.5
- go to S/W Upgrade mode
- go to USB-Debugging (but no driver's found for this)
Can someone help me please?
THANKS A LOT!!!
have u done NandroidBackup before flashing to CM10?
Now I have the same problem too

Any ideas?

..yes, but the backup is broken.. .
I had the hope, that it is not a big problem, because I had a LG E400, there I could flash back to stockROM without any kind of problems.
I think, the BIG PROBLEM is, that the CM10 flash gives the P720 an other serial number, IMEI is still the right one. Any try to flash back to stockROM stops with mistakes.. for example: "magic number does not concide"
Maybe a chance to change the serial number? (the S/N on the BOX is an other than in the phone!!!/IMEI still correct)
Thanks for help!

Yes you can use smartflash but you must first extract it to bin and fls files using this tool http://www.mediafire.com/download/xbxacly4195v7xb/LG-P970+ROM+COVERTER+2.1.exe

[Q] Help!! Only fastboot mode.

Please, need help.
My mate only starts on fastboot mode. Can flash stock and cwm recoveries, but dont works. No dload. Nothing. Please somebody who knows what to do.
Thanks a lot.
I'm having the same issue on my MT7-L10. I flashed the stock firmware (extracted from the URL consumer.huawei.com/en/support/downloads/detail/index.htm?id=32364 using update.app extractor) using CWM and the phone never boot up again. It only shows the Ascend logo and stops there. I've never had any problem using CWM to flash firmwares on it before. So I am assuming the extracted firmware is the cause.
I can access the bootloader and flash recovery (both custom and stock) or boot img, but the phone would not boot up. Since I can't get to the recovery, there wasn't much else I could do; let alone, flash the backup. It had been 2 weeks since that happened and I tried many methods but found no solution online. Might as well give up on it unless there's a real solution for us.

If you installed CWM it is logical that you can' t install stock ROM, neither 3buttons can start...
This has been already discussed and repeated so many times before.
Please, be so kind to use the "search" button next time and give a look in the proper section of this FORUM.
You would have fount the "solution" in a while, instead of asking.
Please consider this next time. Thank you !!!

I took it to the Huawei service center. A week later, they called and said that it was a defect on motherboard and replaced it for me. No solution on my end.
