LG V30+ (H930ds) IMEI Repair - LG V30 Questions & Answers

Hello,
As the title says, after multiple flashes of the kdz rom and other via twrp, I got the error message when inserting the sim card, that the phone was not allowed to connect to the mobile network. By dint of searching, I saw that the two imei were at 0. So I followed the various tutorials that hang out on xda and other websites, I could as you can see restore via qpst the imei of sim 1, but I didn't find a way to restore the one of sim 2.
To restore the imei of sim 1, I used RF_NV_Manager (position 550) with which I could do the procedure without any problem, for sim 2, unless another solution exists, it seems to me that I have to make a backup of the nand in qcn format, which I did, to then change the imei of sim 2 into hexa. Problem: I don't know at which address I should fill it in. On the other hand, I was able to locate the location of the imei n°1 that I just reflashed, but it's not very useful to me (00009c20 -> 00009c28).
Can someone give me the address of their imei number 2 in the qcn file, so that I know where to give mine?
Thank you.
PS: Before shouting illegality, as you can see, I do not seek to change the imei, but to return the original ones.
PS : Sorry if English isn't very good.

Bonjour,
Comme le dit le titre, après avoir flashé à multiple reprise les rom kdz et autre via twrp, j'ai eu le message d'erreur lors de l'insertion de la carte sim, comme quoi le téléphone n'était pas autorisé à se connecter au réseau mobile. À force de chercher, j'ai vu que les deux imei étaient à 0. J'ai donc suivi les divers tutos qui traine sur xda et d'autres sites web, j'ai pu comme vous pouvez le voir restaurer via qpst l'imei de la sim 1, mais je n'ai pas trouvé le moyen de restaurer celui de la sim 2.
Pour restaurer l'imei de la sim 1, j'ai utilisé RF_NV_Manager (position 550) avec lequel j'ai pu faire la procédure sans problème, pour la sim 2, à moins qu'une autre solution existe, il me semble que je dois faire un backup de la nand au format qcn, ce que j'ai fait, pour modifier ensuite en hexa l'imei de la sim 2. Problème : je ne sais pas à quelle adresse je dois le renseigner. J'ai en revanche pu repérer l'emplacement de l'imei n°1 que je viens de reflasher, mais ça ne m'est pas très utile (00009c20 -> 00009c28).
Est-ce que quelqu'un peu m'indiquer l'adresse de son imei n°2 dans le fichier qcn, que je sache ou remettre le mien ?
Merci
PS : Avant de crier à l'illégalité, comme vous pouvez le voir je ne cherche pas à changer les imei, mais remettre ceux d'origine.

Can you share .qcn file?

Here is the file before I put the first imei

To change it to hex find a tool called IMEI Convertor. It will convert it over to the values you need to replace in QCN file.
How did you get RF_NV_Manager (position 550) method to work? I tried restoring on my LG K20 Plus but with no results. It would never write, just stalled.

You mean that the value is recorded, but the imei is not taken into account by the phone?
I was lucky, he was the only one who was acting on the phone on sim/imei 1. The sim/imei 2 not average.
But I've changed phones since then.

have you lost your baseband ?. i had baseband loss on my lg v30ds and imei null. so my cellphone can only turn on without being detected by the sim card

Sorry, I was able to return the phone to the seller.
I had managed to put the imui back on sim 1, but never sim 2.
