I need advice on flashing - LG Optimus Black

Hi there, my friend has an optimus black and runs on stock gingerbread firmware. I want to flash something new bcause the stock lags :/ I have a samsung phone and this type of flashing is new to me.
So basically what i will do is :
1.Root the phone by method one in the "starter guide"
2. Install ROM manager.
3. Use ROM manager to flash a new ROM.
Will this work or am i missing something? Thnx Is there any risk, cause i don't want to brick the phone as its not mine .

Rom Manager is what I used after the phone was rooted.

Get a patched rom. V20S is what I used. Flashed with Smart flash. Quit simple. Lots of reads out here on howto.

As for as roms go after u root the phone there are plenty. Sable or not is the question.

Thnx for reply but are there risks of hard bricks? Does Optimus black has flash counter?

flash counter? i don't think so
best solution is to install cwm as you can get out of troubles such as bootloops and other things faster
if you want best stability, try zeus rom but if you want jellybean, you can test it

No flash counter. It's possible to hard brick if you modify bin files you flash from SFT. Flashing ROM you can only get bootloop (at various stages of the boot process depending on how far it fot ). adb is usually accessible buy you can recover using SFT or LG R&D.
There's no know solution to recover from hard brick. LG emergency recovery tool requires working first stage bootloader.

[Q]Should I use CWM or odin to flash 4.0rom like romow?

I know this is a very stupid question but I just want to make sure flashing with CWM is viable.
For the leaked stock ics 4.0 rom I know I should use odin to flash, but how about custom 4.0 rom like Romow? Should I use CWM to flash the zip file?
Thx~
ps: I am currently running rocketrom v19 with CWM
use CWM n flash zip

You should read in the post how must it be done, you should start in annual kernel 3.9 then install chainfire.repack and so on
Sent from my GT-N7000 using xda premium
There are no instructions in romow's thread and that's why i am here to ask for any further instructions. I bet flashing a 4.0custom rom is similar to flashing Gingerbread rom. Am i right?
Also, some ppl claimed that I need to first flash the stock leaked 4.0 rom then have my phone rooted with CWM installed and finally flash custom 4.0 rom with CWM. Is that really necessary?

There are better roms now than ROMOW's one i think, try flashing Rocket Rom, or the new AOSP
From the instructions given in [02/24/12][Team Rocket ROM][open beta ICS v4.0.3][v1.5][15Tooglebar] daily ROM now! , it seems I really have to flash the leaked ics rom first before installing the rocketrom 4.0.3 rom, is that true? That means I cannot directly install the ics rocketrom from any gingerbread custom rom?

Just have to ask it right here as well...I went to romow yesterday for testing reasons (just flashed the zip in cwm) but I have to go back since there are too many bugs imao atm.
Just tried to go back to my CWM Backup....now I´m stucked at the bootanimation!
Do you guys know what could be the reason here? And what I could do to get my nandroid backup working again?

Did you flash 4.0.3 directly from gingerbread rom? BTW I've heard many people say their phones were stuck in the bootscreen(The samsung N7000 with no boot animation) when they tried to go back from ics to gingerbread. Seems this is a common problem....

Yes, I came directly from GB!
If you can load the boot animation that means ur phone is not bricked. You should try to download a stock gingerbread rom from dr ketan's post and flash it by odin pc.

When going back to GB, i kinda 'restart' the whole process by going back to Stock ROM via Odin, and redo the root and CWM.
Else, there are strange quirky issue ex. CWM just hangs while wiping the phone.
Hey Kelvin Fong & J.wong, thank you guys for your support!
Sorry for noobing around from now on...I´m not exactly the newest guy when it comes to these flash-things, but I have to admit that I´m kind of confused now...

dr.ketan said:
Now How I can revert back to Stock ROM/Unroot (In case of replacemet may i need)
If You have Root + CWM - then first find out original stock kernel (zImage file)
Now place this file in zImage folder, n repeat procedure(Initial CFRoot Flasher), which you have done at time of pushing CWM by selecting I am rooted already
Now unroot with above said unrooting tool.

Should be this one(http://forum.xda-developers.com/showthread.php?t=1424997).
Firstly, download one of the roms from [Older ROMs (Directly Rootable)].
Secondly, follow the [Installation Guide For Older ROM ], the one using odin pc.
You may see below another flashing method using mobile odin, but that doesn't suit you since that one requires your phone rooted before and will keep your root after flashing. The one with odin pc will wipe out all your data and apps(of course not your SD card) and also unroot your phone. That means your CWM and root will all be gone and you have to follow another post to root it again(now this one:http://forum.xda-developers.com/showthread.php?t=1329360)
this one(http://forum.xda-developers.com/showthread.php?t=1424997)teaches you how to flash a rootable gingerbread rom, but not rooted. This one(http://forum.xda-developers.com/showthread.php?t=1329360)shows you how to root your phone and install CWM. I think these two posts are the best tutorials you are looking for.
I think you should download this >>http://forum.xda-developers.com/attachment.php?attachmentid=907734&d=1329574136
This one is better organized.
Thanks mate! Saved it to my desktop...but finally i was able to manage the problem by simply flashing a *fresh* RocketRom again (?!). I thought it would be worth a try...
Anyway: Thank you very much for your support, it´s good to still meet that friendly kind of people with patience here on the board (it´s getting less these days) hope i´ll be able to return the favor in future
You are welcome! Please note your binary counter may increase if you flash a rooted rom like rocketrom you've mentioned above directly via odin.

As far as I remember I made my very first steps with odin after I reveived my note (root, cwm)...rocket has been flashed by using cwm. But yes, my binary counter increased definitely...
...I do have a USB Jig, but in some was I am kind of afraid of going trough this! To fumble around in pure darkness...hmmm i don´t know
Have you tried it yourself?
Actually I've got a yellow triangle together with increased binary counter as I followed another tutorial guide(I should follow dr ketan's guide before).
I think removing the counter with a jig is way too dangerous for me so I don't want to risk it. Simply remove the counter only when you really need to bring your phone to samsung because maybe you don't even have to claim the warranty at all.

Which method do you think is much easier to get 100% SUCCESS on ROOT

Question: Does this method of rooting your Black leave the Phone untouched?
Cause my mobo died on me - and after the repair i got it back from maintenance with Stock V20N on it. I flashed then V20C, rooted it with SOC and put my Nadroid backup on it. I had then to install the LG Update (cheat with own little Webserver and edited LMHOST) to update to V20N / V20O. Now i am on V20O......
I have finally the phone and layout i like but miss root to Backup the current ROM.So after playing hours with it - and the upcoming CMW9 or Miui ROM around the corner - i need Clockword Mod. So question again short:
How to root V20O without losing settings / data / apps?
Pls advice and sorry if i overread the solution in some of the threads - i read them nearly all....

that method is for rooting GB right? but what about installing CWM?
Got my new OB and its on GB v20b..
That method is for flashing an already rooted version of v20.
Flash it (use the same version as you already have and make no wipes after)
then install superuser.zip and you ll have access to CWM.
That s all you gotta do.
Or flash v10a or similar with smartflash, root it, install cwm and then install any custom ROM you want. That s probably even easier.

v20o root does not work
hi there,
first of all, I'm a noob in rooting and flashing, etc. I have a question regarding the mentioned v20o flashing (by SergovnikRZM):
I downloaded and installed all files, but in SmartFlashTool the start button is grey, I cannot start the process.
Also I cannot choose the Com Port and the LG Mobile USB serial port as the picture shows.
What should I do? Do you have any idea?
(I have a v20o Hungarian rom and the OS is xp sp3)
Thanks in advance and sorry if it's trivial but it is not mentioned in the steps..
How about enabling windows enabler? If your on Windows 7, you should run it as admin. you need to click on windows enabler, till it shows ON.
Ok, I will try, but this step was not mentioned...
(os is xp sp3)
when I tried the KDZ update I had to run windows enabler, and it was working well, and as I see this tool is also included to root, but this step is missing
Anyway, thanks your reply I will try it

As the install guide says you are meant to flash the repack and then go into recovery and flash the rom. You will likely need to flash a gb kernel via obin and then do as hia install guide says

Ok, thanks for your help so far.
So you mean the PC version of Odin. In which state will i have to bring my phone in order to do so? Where do i get the GB kernel from?

Well i am not 100% sure, tbh your safest route would be to re flash a stock gb rom then root it and then try again just to make sure theres no issues, in which case you can download a gb rom from the sticky in the dev section (make sure its a older rootable image!) and flash using odin while your phone is in download mode
please start at http://forum.xda-developers.com/showthread.php?t=1424997 then/or http://forum.xda-developers.com/showthread.php?t=1329360
i am hoping of course, that you can still somehow manage to get into download mode.
I has almost the same issue! I am running speedmod kernel and i want to put back the cf-root 5.3 kernel so I flashed the tar which was included the zimage via mobile oding and after reboot the phone gave me a blank screen and no recovery! only downlaod mmod where I can manage to flash speedmod again via pc odin...
why is that happend?
Come on mate have you even read the opening page for the liquid smoother rom on all opening pages it tells you to the letter how to install and yet you don't follow it and wonder y you have a black screen. Have you installed clock work recovery after rooting your note if not search how to install cwm on you tube cursed4eva is a brilliant guy who spells it all out for you- . Please don't use the fact you a noob as an excuse as I'm probably newer than you but can read and follow instructions to the letter as the developer knows best.
W00t! The phone came back to life! Thanks alot.
Now, what i dont understand is that repack_lp1 thing. I downloaded I9220LP1-N7000-ICS-REPACK.tar ... now do i flash this one using mobile odin? Will this install the CFM?
Look for cursed4eva on YouTube watch the video were he shows you how to install clockwork then read the op of liquid smooth rom simple !
Please do some more research before randomly flashing files without having any knowledge as to what they do.
Before you start fiddling with repacks and leaked ICS based roms, read this: http://forum.xda-developers.com/showthread.php?t=1633938
If you still think it's a good idea to flash anything based on the leaked ICS builds, go to the thread of the rom you want to flash and read the instructions. Again, read the instructions and then to be sure read the instructions once more.
Then follow the instructions step by step and you're good to go.
From my rooted GB Chrack's rom I just used PC odin to flash AbyssNotekernel42CWTouchOriginalLogo.tar then I flashed Liquid Smooth rom without problem. However you should follow the instruction from their website.

Error while flashing Rom with CWM

hi.
i have an Australian N7000B Note, and it is currently rooted on the latest available android in the country for the phone (2.3.6)
i have superuser and CWM installed.
i can boot into CWM and navigate with no worries, but whenever i try to install any custom rom, regardless what rom it is, i get the same error.
i really want to get off this crappy rom that Telstra provides with the phone, so any help is greatly appreciated.
many thanks
pic attatched of error.
Use ODIN to flash a stock ICS or GB ROM and then re-root and add cwm and try again
the issue you face is because your version is the GT-N7000B and the build.prop is for the GT-N7000 so its failing because it believes the ROM is for a different device.
if the product codes do not match up in the build.prop it will fail - this applies to all devices and all ROMs.
you could also open the .zip and find the build.prop and change all of them, But its a pain in the ass !

Put your details in there and it will find you a stock ROM. Ive seen threads where N7000B users have flashed N7000 ROMs without any issues.
EDIT: You CAN use any GT-N7000 firmware !
Awesome! I am downloading the Gingerbread Australian Rom as we speak for the N7000. if i flash it with odin, root it, and then install CWM would it work with installing custom roms such as paranoid android etc?
Yes because the Stock firmware will remove the 'B' and you will have no more install errors
Be sure to follow the instructions to the letter !! and make a nandroid before commencing.

you can wipe before or after it makes no difference so long as your on GB.
Dont ever wipe on ICS unless your on a safe kernel.
But do do a wipe as it will start you off on a fresh clean install

Best Rom to solve My problems

Hi,
I have since Fev. 2012, a optimus black, but since the beginning I have problems with him.
Before, I was unable to take pictures, because every pictures I took was corrupted.
Since I upgrade to V30b, this problem was solved, but now, sometimes the message: The SD card was removed apears, and I need to reboot the phone. I installed Beyondpod to ear pod casts and all the downloaded pod casts file, after 1 day were corrupted (files with names like:┬▬¶, before the photos were the same names).
This week the phone blinked non stop, I needed remove the batery, and all settings were reserted.
Now I think my battery drains so fast, I had reserted all settings to factory defaults and now the phone is working, bus Podcasts no.
I´m sick of this phone. I wants some custom rom to see if the phone improve.
Can anyone please can help me?
Please give me the information about witch Custom ROM is better. (fast, clean, battery, in all aspects)
Tanks a lot for the help.

is it rooted ? if yes, then you have lots of option in developer sction, the most stable rom i used recently are Marvel v11 and IZS both ICS based roms. both are great with battery and run pretty smooth.
you can try one of the Marve based stock V30F . i didn't try it yet.

If it's a rooted v20 (GB) just install ROM Manager from play store and maybe first try a Marvel12b, 11 or even 10 ... where you get a touch 5 CWM recovery with it. Than you probably have the best base you can get to install any ROM.zip from.

I heard there is one way to install a CWM on v30, but normaly you only brick your phone when you try to get a CWM on v30. Look for unlock U boot.

yeah, this is a way, but cwm 6 have bug sdcard unmounted, use recovery.img 5.xx.xx on this case.
IMHO, if you have SFT, it's safe to flash with Preinstallation for IZS ROM (SmartFlash): includes Smartflash and latest LG USB drivers =>

you should have, ics rooted and cwm on one shot. after you can make nandroid backup and test all custom rom you want.

Case C: you already are on a new ICS rom without CWM
Quote:
- If you want, use OnlineNandroid to do a nandroid backup of your phone, I'm not responsible of your data losing
- Use Smartflash to completely flash (.bin and .fls) a V20 ROM patched with CWM with V30 baseband (you can
use my PRE_IZS_IMAGE available on my blog)

Once again let me thanks the help you gave me.
Now I am confused.
There is any tutorial to help me install the rom?
I am a newbie in this matters. I had a Galaxy tab 7 (p1000), and in that time I did install some roms, but time pass, and now I´m super confused.
I read several thing but, you gave me different solutions and I don´t now how to do.
I think the best rom (following your´s advise), is the MARVEL.
I found this: http://forum.xda-developers.com/showthread.php?t=1554274
And I choose the last: Marvel v G based on Ice Cream Sandwich 4.0.4 v 30d France - deodexed and zipalligned
Following the instructions of the link, I only need do this:
1. You will need a rooted Optimus Black and boot in CWM Recovery or use ROM Manager.
2. Copy the zip file in SDCard.
3. Install zip file.
This is correct?
I need to root the boot? How can I confirm is I have a rooted boot?
SaschaKH gave me this link: http://forum.xda-developers.com/showthread.php?t=2160394
Can I use this instructions to root the boot?
For all operations I need the CWM.Can i install in play store? I found the ClockworkMod (ROM MANAGER) free version. Can I use this version?
Exist also the Rom Manager Premium, for what I need, the free version is OK or I need the pay version?
To finish: What is:
1- SFT?
2 - deodexed and zipalligned?
Thank a lot for all the help.
Sorry for this questions, I want to learn more about this world, and I´m starting. I count with you guys.
Thanks a lot.
Once again sorry for all my questions and my bad English. (I´m Learning English too)

You didn't read it well. It says to root your phone and to boot to CWM. The thing with U-boot is to get rid of the locked bootloader wich gives you an LG Security Error if you install any alternative recovery.
You can follow the instructions given but I didn't try it myself.
What I found easier is to do as NOOBY wrote in his tutorial : flash a V20 patched rom (Gingerbread stock rom rooted and with CWM), like that you'll only have to do the wipes required in CWM and then flash Marvel Rom - which of course you put on your sdcard -.
SFT (= SmartFlashTool, for flashing a firmware easily)
Btw to use that tool you need of course our phone's drivers installed.

You are rigth.
My English is not the best, and I´ve some difficulty's,
I read all thing you gave me, and now I think I´m ready to brick my phone :laugh::laugh:, correction: to install a new ROM.
Thanks a lot for the great help.
I said I'd brick my phone and it seams i was right.
I install CMW and I choose "backup nandroid", the phone turned off and now appears the LG logo and the information Security Error.
How can I fix it?
I will try this:

I had selected the option "backup current rom"
And after, the program installed something, asked me permission to reboot, and appears the problem.
I install again with SFT a V30b rom.
I need to start again, but now I don't know what I did wrong.
Hum... If you installed CWM directly from a stock ICS rom, that's normal that you had that error. ^^

Yes it is what I did.
Is any other way to install CMW?
Even in the tutorial said: "Then you need to install CWM (Clock Work Mod), you can do this e.g. by downloading ROM Manager, install it, open it
and find Install Clockwork Mod Recovery. Hit it, wait some seconds and click LGE optimus Black. Wait again, till the file has been downloaded and installed and your all set Now you can reboot into Recovery, with the second option. It says, what it does: Reboot to recovery"
But I tried also reboot using the option "Reboot to recovery" and the phone reboot and reset with factory defaults.
How can I use other way?
Thanks
In the tutorial it says that for Gingerbread rom.
I don't remember if it is in Ilko or NOOBY's thread but you should use SFT to flash a patched Gingerbread rom. Since it is rooted and with CMW, it may be easier to you for flashing another rom from that.

Back on track.
I made it. I installed the Marvel G, but my problem still maintains (I use BeyondPod) and in the podcast folder appears a lot of corrupt files), I don´t see any change from stock ROM, but I think this is the objective of this ROM.
But now I am ready and prepared to install all ROMS I Want using the CMW, and install from zip file.
I will continue testing some ROMS.
Witch ROM do you recomend? I don´t need fancy style or other complicated thing, I just need what a stable, low consumption batery, and fast thing.
Once again thanks a lot for the help
