I followed the commands but received the following at “fastboot flash modem NON-HLOS.bin”
target reported max download size of 536870912 bytes
sending ‘modem’ (41725 KB)…
OKAY [ 0.882s]
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.917s
All remaining and prior commands worked. Does this mean that my previous modem was not overwritten? Before proceeding with attempting to flash TWRP and then the LOS 15.1 rom I want to make sure I correct any problems.June 9, 2018 at 9:57 PM #38578nopeMember
I got tired of waiting for a response and flashed TWRP and LineageOS 8.1 5/13. That was successful this time. You might want to note in your instructions that anyone with my bootloader version will have to upgrade to a newer version before flashing LineageOS 8.1August 2, 2018 at 9:41 PM #42165joheliMember
problems with bootloader-flash
After testing the last lineageOS-version I wanted to go back to stock-nougat to have a working camera for vacations. However there was a problem with flashing the gpt.bin and bootloader.img. I got a “moto boot prevalidation flash (FAILED) remote failure” as a result. After researching the error on google I read about other people having this problem, but that it is possible to continue without flashing the bootloader. Indeed, the ROM booted succesfully and everything seemed to normal. After a while I noticed that the simcard wouldn’t be recongnized even after several reboots. It turned out that my phone had forgotten it’s IMEI and BASEBAND-numbers (Bootloader: “BASEBAND:<unknown>”, Settings: “IMEI: unknown”) I tried to reflash any of my TWRP-backups and reflashed both the stock- and LOS-ROMs but the SIM would not work again. I’ve read some guides on “how to restore IMEI/Baseband” but they all say “try flashing the stock ROM”. Is there any way of reflashing my current bootloader (version Ax0.52) to flash a full stock ROM or any other way to recover IMEI/Baseband-version?August 15, 2018 at 6:27 PM #44132falcon369Member
Sorry for any disturbing but, there is a problem the camera isn’t working on my phone. Can you please fix this problem? I installed the rom correctly.August 17, 2018 at 3:05 AM #44475August 17, 2018 at 5:55 PM #44574falcon369Member
I did what you said but, the same result. The camera still not working and the status bar 3 clock widgets?
Is the problem because of my gapps or I didn’t flash the root file to my device? Flashing my stock rom the camera is working fine but, flashing this rom the camera isn’t working. Is this a bug?August 17, 2018 at 8:43 PM #44612joheliMember
thanks for your hekp, but I couldn’t follow completely
1. what exactly do you mean by “ceaning all the images”? I tried to wipe the phone via TWRP multiple times with no success
2. my real problem is, that I’m not able to flash a full stock ROM due to the mentioned preflash validation errorAugust 18, 2018 at 6:43 PM #44814
preflash validation fails due to the locked bootloader.
Either unlock bootloader on Motorola phone to skip boot flash validation checks
OR flash stock factory image without unlocking bootloader using the stock recovery mode.
So, it should be Standard recovery and factory firmware image
