OldBB Fix doesnt work on jb for some reason. I have repeatedly tried flashing new bb. The process always fails at restoring the back up, it reboots into emergency, it goes through the burning phase, reboots again and then fails halfway through booting. Then i can restore the nv backup and have my imei and all that back, but still on old bb. I cannot fathom what could be going wrong, should i restore my original froyo or a stock gb rom before flashing new bb? I tried on cm7 and on cm9. Always fails. Any help will be appreciated
[Optimus One, P500, V General] rr0yy:

So i just wanted to share what an idiot I am. Woke at 3 am to do some homework and flash new baseband on my wife's phone, I followed the instructions (i have done this before also), and at the point of nv_restore i got errors. Anyways I was like "cool i have backups" and yet for the life of me I couldn't restore said backups. Anyways flashed CM10 and all is chill, but the sad part is i spent 2 hours on this. WOW.

I so much prefer the Samsung hupla over LG

If you have old baseband, the oldbaseband fix will allow the rom to work with your existing baseband, and yes data.
[Optimus One, P500, V General] FCORivers:
i must be the dumbest guy around here, ive tried this three times and cannot seem to do it right. i got this lg optimus t second hand and first thing i did was flash it with nekos gingersnap. the original rom was 2.2 old bb, i think, so right when the new rom booted i had no signal, as i read on nekos post, i used the fix he provided.

now i wanted to try icysnap but after the process posted here, the phone would just stays off and never boot up again. i power it on and no signal, maybe some recommendations on what to do apart from whats posted on first post, which is very well written.

thanks in advance.
[Optimus One, P500, V General] ibub:
I'm a little confused by your last statements. It does not boot, or you just don't have a signal? Did you try to flash baseband, or just the rom? If just the from, do you have custom recovery installed, and did you make a backup of your previous rom or of the stock rom? If you tried to flash baseband, did you interrupt the process?

Edit: If the phone will boot, and you don't have a signal, there are several possibilities as to why. If baseband flash was successful, but you are still using rom with old bb fix, then that fix will not allow signal. In this case, reflash icysnap without the old bb fix. If baseband flash was unsuccessful, then either the phone was never flashed over ( which would be good thing), or it was partially flashed (bad). Did flashing process seem to go on forever (more than 20 minutes)? If so then the serial port may have been lost in process. I experienced this repeatedly. If it never even flashed then you are healthy. Details please.

EDIT: I think I realize, now, what you were trying to say, that the phone won't reboot during bb flashing process. If this is the case then, as I said before your serial port was probably lost during the process.

[Optimus One, P500, V General] arczangel:
really confused, shameful to say, that I Stucked with Mik's Rom for a long time :o i have the old BB ever since. now i want to taste the JB made by Rashed, and says there that is only for V20 BB.

So what I'm planning to do is, flash this P500-v20G-baseband on my phone now, then flash Rashed's JB.

Now I'm asking, am I doing this right? because If i understand it correctly, after flashing P500-v20G-baseband on my phone, I will have no longer a GSM Signal, but If i Flash immediately Rashed's JB, my GSM will come back and data connection.

Hope Someone can confirm If I'm doing this right. Thank you.

or I can flash now Rashed's JB then just apply Old BB fix.

Thanks!
[Optimus One, P500, V General] ibub:
@ arczangel

Rashed has posted bb requirements for different roms on the op. The v11 versions are for old bb. I use the p500 version on my p509 since I have already upgraded my bb. You may not even need the old bb fix. :)

Edit: To simplify, if you have p500, then use p509 rom. If you have p505, use p506 rom. If you have p506 or p509, then use corresponding version.

[Optimus One, P500, V General] ibub:
My situation was the exact reverse of yours. I had previously upgraded to new bb through kdz (emergency). So I tried using the p509 rom (my device), which gave me no signal. After much reading, I realized that p509 never received the official gingerbread update from lg and T-Mobile in the US, and therefore no new bb. So the rom that Rashed taylored for the p509 was for froyo (old bb). This is why I used the p500 rom which is made for new bb. Viola! I have a signal. :D

[Optimus One, P500, V General] Sandipkim:
which rom you are on?

if froyo and not showing imei then you may have 20v baseband or your nv file not restored(I hope this is not the case), flash any latest rom like gingerdxv29 through recovery and see what you got!

Best of Luck:good:

should i make them?
[Optimus One, P500, V General] Sandipkim:
forget what it says it's ages old now!!

here bb=baseband:p

and I was talking about v10 bb!

See let me clear it to you there are two bb availble for optimus one v10 which is history now only froyo uses that now every new rom including cm7 usses new v20 bb.

if you have flashed v10 succesfully, and not wanna flash v20 bb.

then by replacing above files any(almost) v20 bb based rom(like gingerdxv29) will work on your v10 bb!
[Optimus One, P500, V General] agritux:
my english not good sorry

i copied your files and restart phone

still no imei
[Optimus One, P500, V General] Sandipkim:
It seems like a problem!

now you can do one thing to test which baseband you have!

download this rom!

http://www.mediafire.com/?v5vy8456fwd9aqq

flash it reboot and go into terminal emulator from rom

TAKE NOTE! COMMAND WILL ONLY WORK BY TYPING "su" (W/QUOTATIONS) 1ST

▷NO SERVICE? OLD BASEBAND? USE BUILT-IN BASEBAND FIX!

▷TYPE: "fixbb"

▷HIT ENTER

FYI, SYSTEM WILL REBOOT TO APPLY FIX

NOTE: IF YOU STILL HAVE NO SERVICE AFTER THE INITIAL REBOOT,

REPEAT THE SAME PROCEDURE AGAIN

even after this if no signal then you need to restore nv2 backup file!

I'll help you with that!

and I'm sorry i've to go now for my class sorry!:(

i'll check after 6 hour!

CYa all the best!:good:

@ greengrass

I have had the experience, while testing stock roms, that flashing old bb roms on my phone that has new bb causes the settings apk to force close. This renders the os useless. I cannot comment as to custom roms, but if you are on a stock official rom, you may want to consider flashing new bb rom first. There are also custom roms that will work with both basebands. And, of course, there is the old baseband fix, which allows a new bb rom to work on old bb. Here is a link to my post in another thread concerning testing. Page 11, post 109.

[Optimus One, P500, V General] bejoe905:
Noob here, what do?

I understand everything in OP, but there is one thing I don't understand. In the first line, OP tells us this is a utility for those switching from stock to CM7 or other ROMs based on the new baseband. What he doesn't tell us is in what order to use this and install the ROM of our choice. For example, I have a P509 I am trying to install CM7.2 to, and for the life of me, I cannot figure out how to keep my service. I have used both basebands, and neither of them worked. Am I supposed to install the new baseband, THEN install CM, or vice versa?
[Optimus One, P500, V General] ibub:
@ bejoe

First, you need to know if the baseband flash was successful. Go to settings >about phone >baseband version and see if listed as v10 (old bb) or v20 (new bb). Then scroll up and select status and scroll down to IMEI to see if listed. If all is good, and you've flashed the new rom, then go to settings >wireless and networks, scroll down to mobile networks and select. Select Access Point Names to see if your provider is listed. If it is, then select it, if not, then you will have to add it, along with the settings from your provider. I believe I recall having to do this with cm7.2. Hope this helps. :)
[Optimus One, P500, V General] sweetnsour:
I believe you can go with either method, but when I first installed CM7, I installed the rom first, and then flashed the new baseband.

However, since then, I have flashed back to the old baseband and instead used this fix:

http://www.mediafire.com/?tjyibxdbqyyrmwz

If you want to keep the old baseband but use new baseband roms, you need to flash that fix everytime you flash the rom. Although it sounds like a little more work to do, I think it is better than messing with LGMDP, which can mess up your phone.

3. Android adb : on doing "fastboot erase recovery" it just keep on showing " waiting for device"....

4. LG utils : on selecting "I" option ( for extracting kdz ) the LG utils carshes.

is there any hope for my phone ????
[Optimus One, P500, V General] ibub:
@ ra$h

If I understand correctly, you have already tried a hard reset, with no success. The big question is : Is your phone still under warranty? If so, then possibly the best thing to do is let them fix it. If not, then possibly there are methods to get it back in working order. But if you have not altered the phone (rooting, flashing custom firmware) , then you have not voided any warranty by trying to use the LG update tools. I don't know your knowledge level concerning any of this, although I can see that you have been doing some research. But if all you want is a working phone, you might consider using the warranty ( if valid) .
[Optimus One, P500, V General] Ahish.s:
Install pdanet to get fastboot driver. Then you can erase your recovery and install a custom recovery. After that you can install a custom rom for your phone.

Possibly something was lost, but let's try something else first. Go to settings / wireless and networks /mobile networks. Check data enabled, and scroll down to access point names. Select and view to see if you have any listed (preferably your provider) , if not, hit menu button and select default apn. If your providers apn does not appear, then you'll need to obtain those settings from your provider, or online, and enter manually. If that doesn't work, then we will try something else.
