Hi Guys,

Got a weird error on my phone, and now I can't get it to start up. Instead it boots to a text screen with a few different options, selectable with the volume up and down buttons.

Bootloader logs, Switch Tools mode, Start, Restart Bootloader, Recovery mode, Power off, Factory, Barcode, BP tools, Qcom

It starts up on the Bootloader logs screen with the message

Start up failed:
Your device didn't start up successfully.
Use the Software Repair Assistant on computer to repair your device.
Connect your device to your computer to get the Software Repair Assistant.

AP Fastboot Flash Mode (secure)

And under that is a mirror of whatever fastboot is doing, so luckily I at least know that the phone is still connecting.

I'm trying to start off flashing a new recovery, since I can't seem to get into twrp but whenever I do try to flash i can't get fastboot to recognize the recovery image file. I've tried to use the older recovery images I had but they aren't being recognized either. I have all the files sitting in the same folder, and am using the cmd-here icon to access fastboot. Any idea on what to do? Should I even be trying to flash recovery in this instance at all? I'm stuck!

I should mention that this phone was stock and rooted. I've been ignoring ota updates for months.

I keep getting the message:
failed to validate boot image
ERROR: Failed to pass validation. backup to fastboot

When running fastboot to reflash recovery, It shows this during the recovery portion.

Hmm, on the bootloader screen, do you see OEM_locked or flashing_unlocked status? Those pre flash errors look like a result of a locked/relocked bootloader...

Was there any flashing or anything that happened before this behaviour occurred?

Crap.. oem_locked

I don't know how that could have happened. It's been unlocked for the better part of a year. My phone died, and I started getting all of this when I put it on the charger late last night.

Now I'm having difficulty unlocking the bootloader. I found my old unlock key in email, but it does not seem to be working any longer!

C:\Program Files\Android>fastboot oem get_unlock_data

That's not a good sign - if this happened without warning as you described, it may suggest a flash memory or hardware failure. One thing to try is to flash the stock ROM - here's the link for the April 2018 fastboot ROM https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

If you want to try to save your data, flash using the following commands in fastboot:

fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot reboot

See if that gets your device booting. That should flash the full stock firmware onto your device and satisfy the repair requirements if the flash was successful.

And @sd_shadow this threads should be used more to prevent creating useless threads in Q&A section (speaking for every device)

 

[IronTechmonkey]

This is a wonderful thread. Thanks op.

True that. Across several years of playing with CM/LOS on numerous devices this has been one of the most informative device-specific but non ROM specific threads that I've encountered. IMO that niche is sometimes overlooked since many such threads focus on the intersection of a specific device and a specific ROM. In turn some of the knowledge shared here spills back into the LOS specific threads.

I want to install a ROM on my moto g4 plus but I have never installed a ROM before. Can anyone tell me exact steps/requirements to install any ROM?

You need to unlock your bootloader after that you have to install a custom recovery https://forum.xda-developers.com/moto-g4-plus/how-to/guide-newbie-resource-thread-t3386584

The recovery mentioned there isn't suitable for every rom, especially the 64bit based roms. So if you master to unlock bootloader you should decide which rom you want to install. In the roms thread there's mostly given a link to a special recovery that meets the requirements of the rom(like ressurection remix official).

Is there anyone who got benefited by AKT? I seriously doubt it did anything at all. Didn't notice any difference. Also does it mean if we add Hal3 manually in build prop we get pro mode in any rom? And what about slow motion? Can't it be obtained in a custom rom?
