Dangerous things while flashing - LG Optimus Black

Hello guys i want to know what is the dangerous things the you mustn't (not shouldn't)do while flashing
why ?
because I have had optimus p 350 I released the battery on emergency mode(somthing like s/w mode) and phone damaged and I forced to replace it so which thing we mustn't do in OB development to avoid and prevent this things
thnx a lot

Do not turn off or reboot the laptop. Battery fully charged. Do not disconnect the USB cable and everything will be fine. I hope . It's for smartflash. When you have bootlop after flash by CWM you can always to flash phone by smartflash. Beside it's great way to back factory rom when you need it for warranty.
Carefully follow instructions for smartflash !!!!!!!

I think that as long as the phone's hardware isn't damaged, you can flash your phone again with SmartFlash.

In fact we have more than that
the previous phone when I removed the battery the motherboard damaged

After bootlop when I flash from CWM some times I taken of battery from phone and all was well. But in other hand when you have bootlop you have to take off battery and to prepare for use smartflash
most safely to flash with CWM but you have to remember to do wipes

Bricked Note

I have been searching for a solution, but haven't found any..
I flashed to kingdroid rom a while ago from stock GB with abyss kernel. Everything went fine, and later wanted to try a new rom.
So I wiped the data and factory reset in CWM and tried to restore the old stock GB. I don't know if anything went wrong in that process, but now I can't even turn on the phone? I can't boot up CWM either?

Can you enter download mode??If so flash any GB rom.If the flash is getting stuck at factoryfs or somewhere for long than 15 mins..you have superbricked your phone by doing a wipe.Only way is to replace the mobo or trying this
yeah go on download mode. Use odin pc. It will raise the counter, but its much better than a brick note.. Hehe
Download mode is volume down, home key and turn on key right?
Doesnt work.. how long is I supposed to hold it in?
And what is a MOBO?
Easy ... Don't Panic

The First Thing you did was right, since you did the wipe using the AbyssKernel kernel, witch was safe and away from the HardBrick Thing around the Stock ICS Kernel.
But what you did wrong, is that you did wipe and restore using the Kernel inside the rom you used, wich of course was in cause !!!! so Here is what you will do, just Follow the Steps in My following Post, and you are done

Glad to hear kimifender!
Sorry for not being that bright in all this.. But how can I do all the instructions when I can't turn the phone on? I can't find the sdcards on my computer either when i connect the phone to the computer
Sounds like you have a big paperweight. You need to somehow get it to a Samsung repair center to get the motherboard replaced. There's a thread in the General section that MIGHT help revive it, but no guarantees.
Always make sure you read, read, read before you flash anything. Like other people said, the restore is what bricked it.

He said he wiped after beeing on the other rom. So he wiped with an unsafe kernel.
=> Superbrick.
So there is no way I can revive my phone?
Maybe im just not turning it on the right way?

If you're pushing the power button, you are turning it on. If you are holding down volume up/down + power + home button you are trying to put it in download/recovery.
Sorry, but it sounds like it is a paperweight/brick.

Check battery. make sure it still has power. Pull out and leave out 5 minutes and replace it back as well.
Then turn it on and try to enter download mode (Home volume-down and power) and connect it to PC odin (even in case the screen does not turn on) and see the yellow box is there. If there is, you can flash kernel that has CWM as well, and there is hope to revive it.
If you cannot get odin to see it, then SS service is the only way.

Well Of course, If your phone is not ON, it won't show any usb storage on the PC.
Don't Give up Yet !!!
Are you sure your phone has enough battery charge,
Not Sure? well Do this :
- Keep your phone under AC Battery Charger (no USB charging) for at least 45 min.
- Take Off the Battery for at least 10s seconde,
put it back, Then try to to enter to download mode directly : Vol down + Power + Home Button at the same time untill you see the Yellow Dowload Logo, Don't Try to turn your phone on by Pressing the power Button as Normally, It Simply won't turn on !!
Keep taking the Battery Off and Back untill it works, believe me this happened before.
How much would it cost to get it fixed?
How much would a new motherboard cost?

I really doubt that will work if he has a superbrick. If it does it would be amazing.
But how can i flash, when I can't even turn on the phone?

Try what I told you in Post N°12,
If you get the chance to get into the download mode : then Follow My Post N°5.
You Have to Make sure your phone is really Dead, or just need a push to wake up again.
I swear this happened to me before, and believe me I'm no noob.
Just Try First. If it doesn't work, then Buy another one ;;;;
how i fixed it
Iám new as a member here but not new on reading here on this forum.
Want to post fast how i brickt my phone with ics and kernel problems and wipe going wrong.
Cwm still working but nothing is going anymore.
In cwm flash a franco kernel (i used Franco kernel 10 because had it on my sd card) then reboot into recovery and flash the Abys kernel.
Reboot into recovery and install your rom or restore an backup you made.
I hope sthis works for all.

Out of ideas, plz help

| Did a hard reset/factory reset using SmartFlashTool and still no luck. The phone keeps powering off (as if you were pulling out the battery forcefully from the back) after booting for a min or so when plugged in. When on battery alone, the phone wont boot at all, it just flashes the LG logo for a few times and dies (like turning a lamp on and off). I'm running out of ideas :S
Did you drop it or did it get wet? Is the Download Mode screen being shown for a longer periode of time, or how were you able to use smartflash?

| Nope, Nope, Nope, I was able to use SmartFlash just fine. When plugged into a power source, the phone did a factory reset and I was able to boot into froyo for a minute or so, and then it dies (like when you're pulling the battery out forcefully).
Try the following:
Download any kdz file, download cwm injector (look into my noob how to post 3), inject cwm, flash it with smartflash, then you should be in CWM, do a data, cache and dalwik wipe, flash superuser.zip (should be on your SD card of course) and try to boot again. If it still doesnt boot, I have no idea, of what is wrong with your phone...
I think it's hardware related. A link betwen power supply and motherboard.

I think it's a hardware problem too because smartflashing it to original rom still won't solve the problem. Guess I have to take it back to the store that I bought it from.
Try using it on USB alone with battery removed if its working normal, then it could be a faulty battery. If you can lend the same battery to test would be better than buying one then realizing thats not the problem but could be hardware problem.
Hmm, had u followed the correct steps about using smartflashtool?
Change the battery?

[Q] problem after doing wipe cache partition on cwm

Ok, so my phone is rooted and i was going through the steps before applying they cyanogen mod 10 nighly.
In cwm i had:
- Created a back up
- Wiped data / factory reset
- Wiped cache partition (it took a wil then the screen went black as if it had reset)
And now i am unable to power 'on' the device?
Any ideas

Do you mean you cant power the device ON ?
What happens when you connect usb cable ? Does anything light up, Does your computer 'beep' to notify you of a connected device ?
Have you took battery out and reinserted ? or just left it to charge for around 10 mins before trying to power on ?
Also, What ROM + Kernel were you on before you did the wipes in recovery ?
Ahh yes, in my panic i miss typed.
O cant power on i have tried taking the battery out etc. but with no luck.
I just plugged it into my laptop pc and not a thing
I was on stock ICS (uk) and i don't think i changed the kernel either
I had just rooted and did the super user thing
I also probably didnt fully install CMW as i ran the CWM.zip from external sd from recovery each time.

If you are on stock kernal that implies you are prone to emmc bug, you shouldnt do wipes on stock kernal

You can Revive your phone with a pit file like me. I bricked mine with the same way as you. Check this: http://forum.xda-developers.com/showpost.php?p=26285877&postcount=12
Thanks but I don't know if that will work as i can't get the phone to power on (as far as i can tell) and it doesn't seem to do anything when i plug it into the laptop.
No ping no beep.
It had about 60% power left when i did it so it has juice.
I am thinking might have to take it to carphonewhorehouse and tell them i was just doing a factory reset cos it had slowed down with all the apps and it reset while doing it and now won't turn on?

in this ERA of auto-root kernels, people still using CWM.zip...
probably should have just read some stickies. but too late...
if there is no response from the device, the pits are not going to work. only way is to get a replacement motherboard under warranty,
and as the device is non responsive.. they will not be able to detect anything about root.
Good Luck
Yeah i did some reading, but clearly not in the right place
back to the shop it goes. If you have a guide that you could point me to to get this doen the correct way then that would be much appreciated (if and whn i get a working replacement)
Thanks

when you get the phone check what rom its on. just update to the latest ICS rom..(donot wipe).
download philz kernel for the rom you have updated to.
put it in the sd card
boot into recovery
and apply update from ext storage.> point to the kernel > install
thats it. your phone gets rooted, safe kernel and CWM inbuilt.
now you can follow the procedure in the CM10 rom to install. (The Safe Way)
Thanks!
I have just got back from CPW where the nice lady said that it looks like a hardware fault given what i had described so she is sending it off to be either mobo replaced o plain replaced.
I have emailed myself your guide and will look into it if and when i get it back.
Thanks !

If you really did everything and in a right way, you can start to build a new house because you have the first brick already.But...it's not so easy to brick a phone with SFT.If you really followed the rules for Smart Flash Tool it's practically impossible.I know that people tend to panic in such situations and do something wrong in a rush.Well, take the battery, sim card and memory card out of the phone; hold the volume up button and then plug your usb cable( sure that cable and contacts are okay ), which is pluged in your computer with SFT opened; sometimes the phone enters in s/w mode in a second but sometimes needs five.Then flash a GB rom or anything you want.If nothing will happen is very much possible that you have a hardware problem( something similar happened to me when my motherboard was fu.ked and this is quite common with P970 ).Good luck.:fingers-crossed:
P.S. Are you talking about SE arc or LGE P970?

Well, the phone goes in bootloop when you flash patched files with recovery and then forget to flash Superuser.You must not boot your phone when it enters in recovery after flashing with SFT but flash Superuser from your SD card first.I think that this maybe was your first problem.But LG logo and flashing leds are also a very possible sign for a faulty motherboard.The same happened to me with one week old P970 with official firmware and not rooted, when I tried just to reboot the thing.And if your phone died after this, you can be 99.9% sure that you have a fu.ked motherboard.

[Q] BIG Problem with my OB

i try to install v 20G with smart flash and after the phone was connected start to loading ...
after 3-4 sec was disconnected and now is dead
is not connecting with USB, not start with charger ...
how can resolve this?
thank you
Wrong subforum.
sorry, please a moder to move it ...
If you flashed it with battery inside, you should be able to enter in S/W mode and reflash it but if you flashed without battery you have probably bricked it.It's also possible a hardware failure, like the motherboard.
i flashed with battery inside... allways i do this ... but this time not work ...

This means hard brick or hardware failure.Take it to the service.
damn ...
try to see if atleast your pc recognises it in computer management
doesn't recognized ... i try on other pc and nothing ...

i guess now you should try to search the web or send it for repairs :/

Probably when you start the flashing with smart flash tool at the first second you move or touch your phone and usb connection cutted sft writing bootloader unfortunately.Before flash your phone put your phone a constant can not move and dont touch your usb cable and phone until flashing finish.

that was the problem ... i have a very long USB and i think i touch him ... :| i was to service and they told me is dead because i start flashing with low voltage ... under 3 V ... They can make with JTAG , for rewrite boot or another thing on motherboard .
now i hope to be fine ...
