Hello,

I introduce myself to the forum. Haven't seen if there's a topic for that?


I bought LG V600N and well, when I got it it had 000xxxxxx imei and it also had S/N.

So, I crossflashed EA firmware and everything was working great, but then I realised I didn't have WCDMA 900 wich is a band I need to be able to use calls -switch from 4G to 3G-. Then I start flashing other firmwares, TWN, SWC, TMO and all I could find -A10/A11-.

But it happened, I missclicked on "ChipErase" and my IMEI/SN are gone.

Been the whole day looking for Dev LGUP to no avail, tried all DLL's I've found in on the net and some added extra functions, but not PDM option so I can restore IMEI + SN.

So here comes my petition:

Does anyone please can provide a PDM option LGUP?

Besides, as I saw some of you guys are really knowfull about LG, is there any way I could activate WCDMA 900HZ BAND?

Maybe ... QPT or something like that?

I'm very thankful for the upcoming answers.



[Edit] I managed to get PDM option and restored the Imei successfully, only S/N shows 1234568ABCD.

How can I change it??

Hi, thanks for the reply. Smile

I first tested my LGUP and none of them worked, then I paid attention to the DLL version and downloaded the latest, also updated my V60 to Android 11, openned UI Fixer, followed instrunctions and then it showed.

I got a bigger problem now, my phone says that the Google Certificate Key (Attestation) is deleted and can't do much with the phone (no backup, no restore, no fingerprint)

Not sure if that's the only issue since I guess something is going on with the PDM functions as maybe the numbers not written such as Wifi Adress, BT adress, PID, Suffix may affect?

I'm in trouble with my phone :/

Going to try now the S/N to see if it works.

Thanks again.

I installed Putty 0.76, opened it, wrote the COM port and marked serial option, nothing happens when I try to test the connection by writing AT in the console.

Not sure why, hope you can assist me a bit on this?

Thank you very much.
