This warning also serves to other variants.
I see that many users of this variant are using other variant binaries and images trying to unlock the bootloader and install TWRP recovery.
My advise is to not do this or you can end with a brick.Even worse, when trying to unbrick the phone, people are using other variant nand backup images, this will lead you to the infamous lost IMEI problem, and from this point if you don't have your modemst partitions backups, you are lost.
Flashing KDZ won't recover these partitions, they are unique to your phone and are not flashed in a normal KDZ flash, the only way to flash them is in TWRP or ADB.
I already supplied the proper D410HN Kitkat v10c and Lollipop v20a/b/c (they are the same) unlocked aboots and bootstacks but people insist flashing files from other variants.
My advise is, after rooting your phone, before doing anything else,
the first thing you must do is to backup your modemst1 and modemst2 partitions to make sure you IMEI data is safe. You can make this backup in ADB or Android Terminal app with:
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/storage/external_SD/modemst1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/storage/external_SD/modemst2.img
This will save modemst1.img and modemst2.img in your external microSD. If you want to save in your internal SD, replace /storage/external_SD to /sdcard.
Also, make a nand backup image in case of you need to make a testpoint or direct flash in nand to attempt to unbrick the phone.
Code:
dd if=/dev/block/mmcblk0 of=/storage/external_SD/unbrick.img bs=512 count=323583
This will save an unbrick.img in your external microSD. If you want to save in your internal SD, replace /storage/external_SD to /sdcard. Do not share this file with anyone else, this image have your IMEI data.
Why make your own unbrick.img file?
If you look at the partition table, you will have this:
This ubrick image have your partition table and the partitions until sector 323583 (partition 15 - laf), which is enough to enter in download mode and flash KDZ with LG Flash Tool and make a complete and perfect recover. This also explains why when you flash an unbrick image from a unknown source and variant you lose your IMEI, modemst1 (11) and modemst2 (12) partitions are flashed along, overwriting your unique data.
Keep your backups in a safe place and now you can go ahead and unlock the bootloader, install TWRP, change partitions size and etc knowing that if anything goes wrong, if you manage to unbrick your phone, you won't loose your IMEI.
Good luck :good:
