[GUIDE] How to manually upgrade firmware

[Presterin]

First of all, this guide expects you to have some basic knowledge how to use fastboot, have working ADB/fastboot connection on your computer and understand the fact that this may brick your phone if you mess up.
I am NOT responsible for anything! This will wipe everything on your phone, so get backups if needed.

This guide is written for X720 and supplied files are ONLY for X720. Same procedure will work on X727, but you will have to get right files yourself.
All files are from stock 23S, just extracted, converted and repacked for your convenience.

Read the whole guide before doing anything. If you're unsure about anything, don't do it.

Here we go:
1. Download .zip containing files from Mega: https://mega.nz/#!5boxDYrL!_O-oD05yhiU5FbCmYuf47VH4Qar5RhV5LKwyHa39bWM
2. Extract files to path where you are able to flash them using fastboot (ie. same folder with fastboot)
3. Boot your phone to bootloader (Vol- & Power)
4. Flash everything:

fastboot flash system system.img
fastboot flash boot boot.img
fastboot format data <-- THIS WILL WIPE YOUR PHONE INCLUDING INTERNAL STORAGE
fastboot flash cmnlib64 cmnlib64.mbn
fastboot flash ddr ddr.mbn
fastboot flash cmnlib cmnlib.mbn
fastboot flash hyp hyp.mbn
fastboot flash pmic pmic.elf
fastboot flash tz tz.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash devcfg devcfg.mbn
fastboot flash xbl xbl.elf
fastboot flash keymaster keymaster.mbn
fastboot flash modem NON-HLOS.bin
fastboot flash dsp adspso.bin
fastboot flash bluetooth BTFM.bin
fastboot flash devinfo devinfo.bin​

5. Reboot, and let it boot up (takes some time)
6. Flash TWRP, wipe everything and install ROM (you have done this before, won't write a guide)

get error

C:\Program Files (x86)\Minimal ADB and Fastboot\x720_upgrade_23s>fastboot flash system system.img
target reported max download size of 536870912 bytes
Invalid sparse file format at header magi

 

[Presterin]

I'm only guessing, since many have flashed this successfully, but maybe a bad download or incompatible fastboot.

thx
i will try again.

Does anyone know which ones are safe to flash over the existing rom? I do not wish to wipe or break current rom.

 

[4K2K]

I flashed everything except system and boot on top of Omni rom. Everything works great.

 

[limitlesscodes]

Does anyone know where I can get all of the files for my x727, I considered using the files from these OTA zips but I think some of the files are missing like the modem firmware and system.img.

 

[Presterin]

On x720 some of the files were divided into scatter files, had to do some research to get them sorted.

 

[Signor72]

Which fastboot is compatible with system.img? Because of me too :"target reported max download size of 536870912 bytes
Invalid sparse file format at header magi". minimal fast boot 1.42

Edit: ok..as long as the post I wrote started installation

 

[meangreenie]

Should/Can we install the latest fastboot? Mine is on shop altered 17s from over a year a go, which to be fair runs great; i just fancy a change.

Thanks

First, you provided no information. For example what phone do you have, what OS etc.
I am guessing EUI: It would be alot easier to simply flash the firmware for your device instead of flashing the exact same pieces of it one at a time. By extracting the bits from the full OS.


This is a old outdated guide that has way too many steps, and it was made a long time ago. Since the name of the guide is upgrading firmware, I assume thats what you are trying to do.

Since you are hoping to flash firmware, I will go ahead and assume that you already have your bootloader unlocked, have flashed Twrp and are rooted? You can accomplish updating your firmware with one step. > Go to Lineage 15.1 page and go to downloads section. Here you will see firmware listed, download the firmware to your device. One flash in Twrp will install all of the radio and sensor files needed.


Hint: always boot to recovery first, checking the Twrp installation boxes if present> this is a best practice to avoid bricking your phone.
If you have any issue after following the steps I mentioned ( Its possible because of the fastboot commends) You may need to clean wipe reset and start fresh

Before you begin disable any passwords and fingerprints within the system settings.

• Boot to recovery > click wipe > advanced wipe > check cache ( not Dalvik, just cache) > swipe> press home key to return to main menu.
• Click install >Navigate to your download folder and select firmware > swipe to install > clear cache again> reboot to recovery
• If there are any check boxes to check for TWRP installation, check them >
• Once back in recovery reboot to system > Finished

Great guide Thanks.
It saved me from a system wipe and a nightly not recognized by TWRP...:crying:
