Entao eu não tinha feito o procedimento mais correto. Agora eu fiz o backup e o restore usando o twrp o que aconteu foi que o imei zero novamente mas agora tem chance de conseguir restaurar o dois ainda nao tentei porque estou sem pc. Estou confiante que vai dar. Assim que tentar aviso aqui. Mas uma coisa ja sei a camera nao voltou ainda. Nao sei se tem relaçao com o imei.

Lembrando que eu fiz o backup do sistema todo de um cel qie estava funcionando perfeitamente e restaurei no meu.
[LG Optimus L90] Floating Point:
I tried many ways to recover lost IMEIs but nothing worked. Everytime you manually set your IMEIs hex-editing and using QPST, after the next boot everything is reseted.

If you don't own a backup of your modemst partitions and your own unbrick.img, currently there is no way to recover your both IMEIs manually without backups. Since the unbrick images and bootstacks widely used are from the single SIM version, you can recover just one of the IMEIs.

Everyone after rooting your phone must do the backups as shown in the topic and never flash other variant files in your phone, if you do this I can't do anything, I think it's common sense no never flash files from different phone models or variants to your phone.

Even if you already used other variant aboots and bootstacks, forget D410HN aboots and bootstacks, your phone now is other unknown variant (even if in Android system says otherwise - that info is just a TXT inside a config file), if you try to "go back" to the proper D410HN, you may face problems like loosing your IMEIs, your camera, etc.

Não deu mesmo, usei o QXDM onde existe a opção Multi Sim para tentar trocar o IMEI do SIM 2 mas não deu certo.

F.Gacrux, thanks for supporting Brazilian members!

I tried to backup entire system (all directories including modemst1 and modemst2) from a "healthy" mobile (same variant D410HN). Then I restore on my D410HN. Now I have two cloned mobiles, the same interface, but both IMEI are zeros again and the camero still not working. I thought that after restoring QXDM will recognize Multi Sim option, but when I tried to read/write on second sim it returns the error message: "NV Status Error Received: Item Inactive".

Is that any way to backup NV Items from that healthy using QPST or QXDM?

Sorry for my english, if you can't undestand ask me.
[LG Optimus L90] Floating Point:
That's because you changed your NV table by flashing other variant (probably the single SIM CIS D410H) to our dual-SIM D410HN, and currently there is no known way to change this table to add or remove entries without a full nand image (the infamous unbrick.img, but you must do it with the proper d410hn image, I will explain it in the end why).

I know this happens because I too tried recover someones D410HN from both IMEI lost because he done the same mistakes you all are doing, even using a healthy donor of QPST QCN and modemset imags (myself), everytime the phone would keep only one of the IMEIs after reboot.

From what I saw, there is something even more "low level" from modem, sbl, modemst and encrypt partitions that are associated with IMEI data, and the only thing I believe that will recover your phone is a full dd backup (partitions 1 to 17) from a 100% healthy D410HN that were only rooted and never had any other variant files flashed to it, and flash it the same way you used the russian D410H image to unrbick your phone, after that you must use QPST to dowloand your QCN file and hex-edit it to change both IMEIs to your own and send it back to the phone.

What I want to say is:

1. Get a rooted D410HN, fully working that you never flashed other variant stuff to it. It will work as a donor.

2. Make a dd if=/dev/block/mmcblk0 of=/storage/external_SD/unbrick.img bs=512 count=323583 to backup partitions 1 to 17.

3. Make a low level flash with dd to the target phone with it, flashing the same blocks. This can be done the same way you done with the russian unbrick.img, maybe this can be done in recovery, but I didn't tested.

4. Enter in download mode and flash stock kdz.

5. Root the phone, unlock the bootload with the proper files for the D410HN model.

6. You may now have the same IMEIs as the donor, you now need QPST to download your QCN file, hex-edit it to find and replace the IMEIs, and send back to the target phone. This is a little tricky because you will need a special calculator to convert your plain text IMEI to hex values compatible with Qualcomm tool (it's not a simple TEXT > HEX conversion) and you need to know how to work with HxD.
[LG Optimus L90] BiduBR:
Man... You are L90 xpert! Tks for sharing your knowledge.

Here the usual, stupid user do stupid thing...

I dd wrong aboot.bin and my phone booted as USB Storage.

No, as I said stupid user here and no backups.

But in this point I used minitool partition wizard free and cloned my phone emmc to and 16gb SD card.

Can I recover my modemst1 and modemst2 from this copy or when I dd wrong aboot.bin this partitions get lost ?

If this is possible mayble the recovery guides that tell user to dd a loader.img or unbrick.img can include this information allowing the recovered atc to be fully recovered to initial state.

Thanks for your help.
[LG Optimus L90] rhafhael:
BiduBR, bom como você deve ser brasileiro responderei em Portugues... RSRS

Pelo que entendi ai do seu procedimento você já cheogu a dar softbrick. O mesmo ocorreu comigo e a partir daí já perdi o IMEI e camera frontal, mas não quero te apavorar não. Eu sou noob em tudo isso e estou arriscando tudo que tenho aqui pra tentar recuperar. E apenas complementando eu acho que a partir desse ponto já não seja mais possível fazer o backup dos arquivos modemst1 and modemst2 etc. Mas espera o F.Gacrux dar uma ajuda aí porque ele deve ser o que mais entendi aqui.

---------- Post added at 05:10 PM ---------- Previous post was at 05:08 PM ----------

In step 3 how do i proceed? Giving dd if=/storage/external_SD/unbrick.img of=/dev/block/mmcblk0 bs=512 count=323583 on terminal?
[LG Optimus L90] BiduBR:
Opa, fala rhafhael.

Então a duvida eh se quando faz o flash do aboot.bin errado ele chega alterar algo nas partições modemst1 e modemst2, eu acredito que o procedimento de recovery é que estraga estas partições.

Pra minha sorte eu tenho outro 410hn que foi bloqueado pela operadora por cancelamento antecipado do contrato, então este atc pode me ser util em algo, mas vou ter que me virar com os imei´s.

---------- Post added at 09:14 PM ---------- Previous post was at 08:39 PM ----------

rhafael, Olá.

Mesmo com um backup full de outro atc identico a camera não voltou ? Vc testou com outro app de camera? No CM12 isso reolvia este tipo de problema.
[LG Optimus L90] rhafhael:
F.Gacrux you're the best man!!! 50% work done...

Actually the IMEI still the same, only the first IMEI can be changed.

But with your procedure my front camera is now working!!!

I don't know if its was the best way but i write that command in terminal... then I flashed stock rom...

Maybe we have to use another file on img creation/backup, or change the parameters. Can you explain me what does bs=512 count=323583 are doing in img file?
[LG Optimus L90] BiduBR:
Nice to see an evolution in an old know problem from Lg devices.

Cool.

I guess bs= is the block size to dd deal in data read and the count specify the piece of the image that should be read.
[LG Optimus L90] rhafhael:
Então BiduBR, com o backup do TWRP, que eu tentei não deu não. Aí a questão da camera eu te digo que foi tentando instalar o CM13 que acabei ferrando meu cel. Percebi que com o sistema original ela não funcionava, mas com o CM13 que posteriomente eu consegui instalar da forma correta ela funcionava normalmente.

Então pelo que voce disse e eu entendi... talvez quando se define o count=323583 voce seleciona uma parte específica do arquivo mclbk0 que vai ser salva na img. Sendo assim, esse valor não esta englobando a parte que trata os IMEI's. Se eu não definir ele vai copiar o arquivo inteiro? Já fiz isso uma hora e demorou muito, o arquivo img já estava com mais de 1GB sendo que definido fica com +/- 150 MB.

O duro é que o cel que eu arrumei tem a tela quebrada então toda hora que eu tento algo eu desmonto e troco as placas para usar o tela do meu... Já to cansado de ficar desmontando toda hora... srsrsrs e estou com medo de quebrar o conectores minusculos

---------- Post added at 08:11 PM ---------- Previous post was at 08:09 PM ----------

Acabei de ler o help do comando dd. O count define a quantidade de blocos a ser copiada.
[LG Optimus L90] rhafhael:
F.Gacrux sorry for too many questions,

But can you explain me what is the mmcblk0? Whats the difference between the mmcblk0 on /dev/block/mmcblk0 and /dev/block/platform/msm_sdcc.1/mmcblk0? Qhy you suggest to backup the file from /dev/block?

What if I don't limit the blocks (count=323583) and backup entire mmcblk0?
[LG Optimus L90] Floating Point:
As I noted before, modemst partitions alone won't recover your both IMEIs, since other important partitions may also have something with it. I tried to recover a broken D410HN of someone who flashed the russian D410H unbrick image by flashing modemst partitions alone and it couldn't recover both IMEIs, although system were showing IMEI 1 and IMEI 2 (second one was blank), the phone itself were acting as a the russian single-SIM variant and just the first one were working.

What I learned from this is that L90 variants partitions works together, but since only Android system is open source, there is no way to know exactly what other partitions apart from modemst have something about your phone modem and IMEI data, that's why when you flash the russian unbrick image, all the first 15 partitions from the russian variant are flashed along, and even if you flash the D410HN variant bootstack, system, boot and aboot, at low lever your phone works as that russian variant, and this causes problems such as lost IMEIs, camera and signal problems, etc.

From my previous post, in the end what I said is the only thing I believe that can repair your phone to make it work 100% again, is making the same thing you all did with the russian unbrick img, but now using a unbrick img backup made from a true healthy d410hn variant, and after you'll need some work with QPST and hex-edit to write your proper IMEIs back.

Use terminal or adb. I prefer adb. Make this in recovery so other partitions aren't mounted or in use.

Marked in red, read the first post for full explanation (starts at "Why make your own unbrick.img file?"). You don't need an 8GB nand image, take just what matters (partitions 1 to 15).

/dev/block/mmcblk0 allows you to make raw backups from the nand which includes the GPT. Actually, as dd is a low level command, it won't even know what is actually making backup, it just knows that you want a nand copy from sector 0 to 323583 (512 bytes sectors). These numbers are because we know that partitions 1 to 15 are inside those sectors.

/dev/block/platform/msm_sdcc.1/mmcblk0 show your logical partitions were you can find all them by its numbers or names so you can backup each of them separately just by it even if you don't know where it starts and end in the nand.
[LG Optimus L90] rhafhael:
Thanks a lot F. Gacrux and everybody in this thread. Actually I'm giving up for a while. I really need to use phone and apps. Don't have time to spend trying now. But I will return as soon as I can. Or if someone find the solution. I'm really satisfied with front camera working and the IMEI's are just numbers that can wait to be modified. LOL

This isn't as much as a "help!" question because I got the tablet working again (by flashing a stock blob); it's more of an question to try find out if I can prevent this from happening again...

I was just browsing tapatalk when my tablet froze. I rebooted and saw the tablet kept rebooting to the Asus logo. Recovery didn't work (it kept rebooting after the recovery logo would appear) and the the ROM (KatKiss LP v29) wouldn't boot.

Flashing TWRP again with fastboot didn't work. I couldn't flash the ROM again or use my Nandroid... I ended up formatting recovery with fastboot, flashed a stock blob to get it working again, and then restored from there, but it was a pain.

So I'm curious if anyone can guess what may have happened and if there is any way to prevent it from happening again?
