[REQ] Need help. Unbrick phones with locked bootloader, oem unlock disabled

As I can see this example is for US. Im from Poland (Central Europe). There will be no problem with radio/modem brandwitdth ? Is this for every H791 32GB Nexus 5x ? This dll file looks to be for LG G4, is it ok ?

Same modem is used for both nexus 5x, and for the dll it should not be a problem. LG Optimus G dll can be used for all LG optimus G and nexus 4, LG G2 dll can be used for all LG G2, G3 and nexus 5. And I think that "US" at the end of file name is a short form of USER and not united states, but I cannot tell for sure until you post the device factory version of a H971.

Here's log. FAILED DoDownload Error! After 16 sec and 9%
This phone is after cleaning with TWRP Wipe All. It is Nexus 5X H791 32GB Euro (with last soft MRB08L).
By Device Factory Version you mean H791 or H790 yes ?? If so this is H791 for sure.

The question about radio and my concern about it is made by some notes:

Any solution to flash successfully ?

[01:01:531] Invalid Tot File : Invalid Partition Size(57973760)

Thanks for the feedback. The error is this



Probably it is because of the 3gb system.img I try to flash is too big. Lg usually flash the system.img by braking it up to 10-15 pieces and flash these pieces after eachother. I will make a tot which flashes the system.img that way.

Do you still have twrp on your phone? If so can you still boot into twrp?

Thank you very much for soo much help...
I discovered this too while trying to flash newer system. Its impossible to flash-all by fastboot (zip concering all the main images with system 3gb) becuose of that. It goes successful only while manual flash every partition alone (while fastboot flash system system.img it sparse file into ~512MB parts).
No TWRP, got stock recovery. I thought i have failed and have to send it to LG Service Center, therefore i flashed original recovery (to make it as stock as possible).

Eagerly waiting for new tot file...

PS. I've found out that MBR08L and MBR08M have same release date (1. November 2015), I've tried to flash M version and on welcome screen phone asked me to choose gmt settings (where i didn't found nor Poland or Central Europe), while in L version it doesn't asks and put this settings properly by default. Is it possible that L i for poor countries and M is for States and wealthy ones ??

Try now https://mega.nz/#!c4AmlCTT!LS1urRD8P...FHHe7PBNzzJLak

That M and L thing is just nonsense. If it were that the case then google would have done 2 seperate download sections for the two variants of nexus 5x on it's stock rom download page.

Still error on 17 sec. Log attached. After successful restoring of nexus soft can i flash immediatly (by fastboot) m version of soft?

Ah I was wrong. The problem is the size of the modem.img (57973760 bytes) and not the system.img. I still have to figure it out what is wrong with the size.
If you manage to flash the tot file you can flash whatever rom you want with fastboot after you enable oem unlocking and unlock bootloader.

Ok. I'm waiting for next tots for check.

modem partition sizes in bytes. I think modemstN are the EFS partitions.
