yea by posting in the Q&A section.

help !!
Hi, sorry for my english , I'm french
I wanted to flash a custom rom on my LG G2 D802 .
I wanted the Paranoid Android (PA +) with 4.3 JellyBean .
So I made the
Backup
Wipe data / factory reset
Wipe cache partition
Wipe dalvik Cache
After I
Choose zip ( custom ROM ) from sd card
Then I
Reboot System Now
And turn on my laptop, I get an error message saying
[640 ] started Fastboot Mode
[ 690] udc start ()
I realized I had to flash AOSP kernel before changing to a ROM paranoid . But my kernel is blocked and so I have to go back to the stock ROM
When I did this tutorial using lg tools , flashing stops at 49% with an error message .
I also saw that I could access the recovery mod by following this link http://forum.xda-developers.com/show....php?t=2565904(but I saw that I could not otherwise reboot my phone after it was bricking ) and therefore flash my stock Rom which I had made the backup . But I do not know if the ROM has been saved and if it remained in my files after the Wipes.
If it is not there, is that in buying a micro USB ====> HUSB adapter, I could install a stock ROM from a USB key ? Or is there a way I can put files from my computer to my laptop which has no port micro sd?
And is what I could with my kernel "blocked " ?
Thank you very much

[Q] [HELP]phone bricked!!!

Hi everybody,
I was flashing as normal a new custom rom (Ice Cream Bread - Apocalypse v4.5 link herehttp://forum.xda-developers.com/showthread.php?t=1801184) and once in recovery mode, after have wiped cache, data and dalvik the message from recovery was: Installation from sd card complete.
So I have rebooted my phone and it stopped the loading. After 30 min of any signals I tried to restart my phone and now the only screen I see is "samsung galaxy y s5360". I tried also to put it in recovery mode but when it seems to load the recovery it returns to the first screen(samsung.....).
I've also read a guide for flashing the official firmware with odin but there's no way.
Can someone help me please? maybe I don't use at well odin.
Thank you everybody.

LG G2 in bootloop.

I really enjoying experimenting with rooting my phone and flashing custom rom's.
Unfortunately my phone is in a boot loop now.
First I installed the OMNI rom, worked fine for a couple of days. Then I installed TWRP recovery what overwrote CWM Recovery what was on my phone before.
I wanted to flash PAC rom, I downloaded the rom and GAPP, booted in recovery mode. But when I tried to factory whipe my phone, it took a very long time and my battery went empty so it stopped wipping.
Now when I tried to boot it up it didn't go further then the LG logo. So I booted in recovery again and just installed the PAC Rom without the factory wipe. It was formatting like 10 minutes, after that the flashing continued and installed the ROM.
The Flashing:
######################
Formatting system
Extracting System files ...
Making Sym Links
Thanks for choosing PAC-MAN ROMS
Enjoying PAC-MAN now
Checking if loki-fying is needed
Updating partition details.....
E:unable to mount /cache
It look alright, so rebooted but didn't came further than the PAC-MAN Booting animation.
In the Mount section of TWRP only system and data are mounted. Cache and USB OTG are unchecked.
It says E: Unable to mount /cache
http://forum.xda-developers.com/showthread.php?t=2432476 This looks really helpfull. So i tried it but couldn't get in download mode first.
When I tried to start the upgrade the following happens:
Strat fn_startupgrade
Extract kdz file
kdz decrypt success
Extract file error
Then the program stopped working.
For me a bricked phone is a huge problem. I hope that you guys can help me to fix my phone.
I'm willing to give some money for the time and as a 'thank you' for helping me out.
PM me if it's needed for faster helping. After I will post the full solution here.
Thanks in advance!
Now that the cache is able to mount because I formatteded it with the make_ext4fs function.
Now I have to flash a rom through sideload because it freezes at the LG Logo.
The problem here is that my device doesn't show up in the command prompt because the drivers aren't working (The drivers I installed from the LG website)
I had the same issues with the drivers and sideloading. I just downloaded the android sdk then then went into the properties of the phone in "devices and printers" and had it search the the driver dir in the android sdk. Just choose the android adb bridge and it should be fine.
Did you fix the issue?

please helpe i accidentially wipe all os system and data of samsung s3 neo i9300i

my device is samsung s3 neo i9300i.recently i install twrp 2.7.1.0 and accidently delete all partitions and system and data.so now there are no os system.and i cant boot my phone.phone stucks on samsung logo.but i can boot into twrp recovery mod.then i decide to flash stock rom throgh twrp recovery but it fails and also try cm 12.1 official and unofficial it also fails.its showing no md5 file found.patching system image unconditionlly and updating partitions.so what can i do.i dont have pc.so give me solution which can i solve with twrp 2.7.1.0 .and one que. can i install noble rom 2.1 on this mobile in this situation?please help me......
I think you still need to find any PC with samsung drivers installed and Odin. Boot into download mode (vol down + power) and flash service firmware to recover partitions. Maybe exist any other solutions, but this, IMHO, is what you need to do.
After installing cm12.1, doesn't it boot?
Don't worry about the md5 file warning or patching system unconditionally. If you got no errors (other than what i mentioned here), it should boot fine.
in twrp there is an option of terminal command.but i dont know how to use it.when i click to open this terminal conmand then open systems folders and files and bottom line there is a option of select current folder.so how can i use it to flash rom with this.anyone have idea then please help me
I several times wiped everything at once through TWRP, then just restarted into recovery, copied .zip files for the ROM and gapps from a computer and flashed them, so can't really see where is the problem in your case. Doesn't the PC find your phone as a storage drive after wipe and restart?
yesterday i successfully install nobel rom 2.1 in my device.but now problem is i cant boot my phone.its showing samsung logo and then automatically going in download mod.before this installation i several time wipe every partitition and succedsfully install noble rom 2.1 but cant boot my phone.problem always there.please please help me
Maybe the problem is with the ROM and it's incompability with your phone. What if through Odin you flash a stock ROM from a computer in download mode and then try another custom ROM?
But of course first try to enter recovery and directly flash (another) working ROM, because going through stock with Odin takes much more time and nerves. Also, with Odin you have to be extremely careful to use the exact stock ROM for your device, so this is kind of a last-case scenario.
Plz check the rom u r downloaded is not corrupted
Or download again by any other phone and save it to external sd card then plug it on ur s3 and flash it
plz can any provide me twrp nandroid backup of system and boot partition of s3 neo i9300i plz plz plz

If you deleted ALL partitions, you have to flash Stock. If not, then just install something.

Try to use Google
It'll be faster than waiting in the room corner
Your phone can be turn on, right?
What your last ROM?
Stock kitkat?
Stock lollipop?
This is the tool you need :
Adb program
Lenovo driver
Stock recovery kitkat /lollipop based on your latest ROM
TWRP 2.8 for kitkat or 3.1.1 for lollipop
Stock ROM kitkat / lollipop
The step are on Internet, it's very long even to type here. So, search in your native language.
Hope that helps.

As long as you can access stock recovery you don't need Lenovo downloader.
Just flash stock ROM (kitkat /lollipop) then wipe cache then reboot
partition table is corrupted ..... i donno how to create new one
if u know how to make a new one....
post here.. that will be grateful thanks
