Help post your edited raw-program

Can you please help post your edited raw-program.xml so I could also make use of it as all attempts to get into download mode even after successful download from QFIL proved abortive

finally it boot again i chanced
these 3 files laf , emmc_appsboot , raw_resources
with laf,aboot, raw_resources from h815-usu unlock files
and edited the raw-program to match these files
also change the recovery with twrp
fianaly can boot to fastboot and twrp

Later did edit the partition-p1_global_com.xml, rawprogram0.xml and readback.xml to reflect files from the Usu unlock folder and voila, my G4 is alive. Thanks to you all for your efforts and for sharing

 

[Creear]

There is no need to modify the XML as mentioned here:

and as well directly in the second post of this thread.

I solved brick problem but when I flash g4 usu firmwares my device always bootloops. How can I solve this

how do you flash? fastboot, TWRP, lgup, ...?
and what exactly do you flash?

just TWRP

I tried 3 usu firmwares but while booting sound crashes and starts rebooting and I just flashed firmwares from TWRP

when someone asks you what ROM you try to flash share the exact filename, link or more details.
What QFIL files do you have used? the one from this OP or others?
boot to TWRP and share the TWRP recovery log (see my sig for a howto)

you know that there is a thanks button beyond each post?

good so you flashed LG-H815_Official_v29A.zip and even LG-H815_Official_v29A_keepsTWRP-LAF.zip ?
cool I dont know what I should say then.. pictures say more then words maybe?



so you have bricked your device again as you flashed UsU incompatible files.

Read and do the fastboot flash commands of FAQ #8b)

Then boot to TWRP, flash this: http://leech.binbash.it:8008/lineage/oreo/h815-UsU/lineage-15.1-20180719-UNOFFICIAL-h815_usu.zip
and tell me if it boots or not.

No one can help with such less information.

Always share logs,
share console output,
share screenshots,
share anything you can. Well at least if you wanna get help

Hi,
I'm trying it but i have a NOP fail code 14

https://bpaste.net/show/54ac71d41b64

Did you know about it ? My H815 brick so i tried to flash LGH815 EU Nougat 7.0 BySezerSimsek and the download mode shut during it.
I don't know what to do (except change motherboard....)

Do you have some solution ?

Thanks

Is your device in QDL mode? What happens when you connect it to your pc in the device manager? Do you see a device named qhusb / qdl 9008 or similar?

My device is in QDL mode

Okay in device mode and QFIL

 

[steadfasterX]

My device is in QDL mode

Okay in device mode and QFIL

take out battery
disconnect USB
start QFIL & prepare the files there so you are ready to press the download button (without pressing it yet)
put battery back in
directly when QFIL(!) detects the device press the download in QFIL

the QDL mode is sensitive.
if you wait too long it will fail.
if it fails once you must re-do all the steps above.

Done 15 times and nothing. With and without battery.
I taking less than 1 sec to press download button when Qualcomm is detected.

Nop 14 is the step when we trying to write in memory right ? So i think my memory is crap

Thanks a lot for your answer !
