[GUIDE] Update stock rooted/modified rom to last 6.0 Marshmallow w/o losing your data

Requirements:
you need to have a pc with adb working
a stock firmware on your device (any)
unlocked bootloader
a working backup just in case
Pro:
you will not lose your data / application
Cons:
you will lose all system modification (root, busybox, custom kernel...)
you'll take all the risk of operation (I've tested on my device)
Guide:
some file names changes depending on version so please complete the {version_here} placeholder with the file you download
* prepend "sudo" on command line if you are on a Linux machine
download last version for your device here (if you want to root download the zip file in the section below to speed up the operations)
extract
extract image-{device_here}-{version_here}.zip in the same folder (no subdir)
command line* (or reboot device with vol down pressed):
Code:
adb reboot bootloader
command line*:
Code:
cd {your_path_here}
command line*:
Code:
fastboot flash bootloader bootloader-{device_here}-{version_here}.img
command line*:
Code:
fastboot reboot-bootloader
command line*:
Code:
fastboot flash radio radio-{device_here}-{version_here}.img
command line*:
Code:
fastboot flash system system.img
command line*:
Code:
fastboot flash boot boot.img
ONLY IF YOU FOUND A VENDOR.IMG IN THE ZIP command line*:
Code:
fastboot flash vendor vendor.img
command line*:
Code:
fastboot flash cache cache.img
command line*:
Code:
fastboot reboot
Now you have the lastest stock image and all your data.
Change recovery (TWRP) and root:
Note that we haven't flash the stock recovery, but during every boot of an unmodified system there's a script that do that (supersu usually deactive this behavior during install).
If you had TWRP installed and the SuperSU zip on your device, at the end of the above procedure you can boot directly from bootloader to recovery and go directly to last step:
download: TWRP image (twrp-{version_here}-{device_here}.img) for your device
download: chainfire SuperSU 2.71 on your device
command line*:
Code:
fastboot flash recovery twrp-{version_here}-{device_here}.img
alternatively you can keep the original recovery and use TWRP one time with
Code:
fastboot boot twrp-{version_here}-{device_here}.img
boot in recovery and flash supersu zip

working fine for me, all correct, thanks

Just tried with flash_all.bat. I'm getting the message "Can not generate image". How can I solve this, please?

Thank you, works like a charm!

Same here, cant flash system

There's not flash-all.bat in my steps (that delete you data!), can't give help about it sorry

i've gone your way, but i tried also the flash-all.bat with the -w switch, didnt work.

Tnx mate. Helped a lot

Cant flash the system.img manually. All the other img are working. I get this error message :
Code:
target reported max download size of 1073741824 bytes
error: cannot load 'system.img'
The old system.img from lrx22c works also.
Someone know whats going on?

I think that all who has flashed the developer preview got an broken filesystem or the partitions missmatch.
Before i used the preview the -w update flag worked well to rebuild the partitions, now it didnt work anymore, tried all factory images don to 4.4

Hmm ok, but u got the same problems. So, in this way we had to wait for a flashable zip or maybe ota.

@c3k why do you mention to flash twrp while in steps above stock recovery is not included to flash... ? Doesn't that mean that custom recovery (twrp) is still on device?

Doesn't this require an unlocked bootloader, and not necessarily root, or am I confused?

This requires an unlocked bootloader. But, there are users like us who have rooted the stock ROM.
This guide is meant for the users who has unlocked bootloader with rooted stock ROM.
This guide will also work for phones with unlocked bootloaders with STOCK ROM(rooted or un-rooted).

I had faced the same issue while flashing LRX22C. It got fixed by rebooting the phone and switching the cable to a different USB port. Might work for him too.
PS: I have flashed the images from Linux.

In my case I guess all the issues are from a previous attempt to flash OptiPop ROM. The flashing process it's a little tricky to understand (with that F2FS file system). I remember that after flashed OptiPop and the phone didn't boot, I tried to restore to stock ROM and it was a lot of errors until it worked fine again.

I'm using the newest Minimal ADB.
The strange thing is, that i can flash the LRX22C system.img and all other new lmy47d files but not the lmy47d system.img.
I guess i'll wait for the OTA update and hope it works then.
Tried rebooting and switching port and usb cabel..

You actually don't need to manually install supersu or root. Flash the 5.1 images and then (after the first full boot) flash twrp.
Once you boot into twrp and exit out of it, you will be promoted with a message that your phone is not rooted, and you're asked if you want to install supersu. It's built into twrp.

Stuck in TWRP

So basically I was installing TWRP onto my Mi A2. I installed twrp on slot b using fastboot flash boot_b twrp.img When then trying to boot into the b slot using fastboot set_active b That command wasn't recognized. I tried installing JDK and SDK manager to get the latest syntax etc. of adb/fastboot. I tried everything again and accidently typed fastboot flash boot twrp.img . This made me flash twrp to my a slot too. The new adb/fastboot syntax still didn't recognize the set_active command. So now I'm simply stuck with twrp on both my slots. I tried installing havoc-OS v2.0 for GSI. downloading the img.xz file. Extracting it and tried flashing it on slot a. But it kind of failed. This was the code:
PS C:\Users\noahe\Desktop\Ny mapp\platform-tools> fastboot flash system_b havoca2.img
target reported max download size of 536870912 bytes

I would appreciate some help

It sounds like (at least initially) your version of fastboot doesn't understand dual slots? an older version? You say you updated right? The new version does understand dual slots I'm assuming?
First thing, what happens if you press power and vol UP and hold them both until it starts to reboot?

Stop using minimal adb, use this
https://developer.android.com/studio/releases/platform-tools
Flash the stock boot image and it should work
EDIT: since you tried flashing system, flash stock system again too

If all that results in is you staying in TWRP, look at twrp and hopefully it's one of the newer versions that allows you to set the 'active slot'. Hopefully choosing the other slot and then indicating reboot in twrp will cause the device to boot normally.

I don't know if you can help with this but when trying to flash roms via MiFlashTool i get the error "flash devcfg_a error"
I've tried both jasmine 9.6.13 and jasmine 9.6.15 updates and they both get stuck at this. I even tried another computer.
Do you know if I should try to flash the rom manually via powershell/command prompt?
Because I'm not really sure how to do that.

As mentioned then, just flash stock boot.img, for the version that your device is currently running. The various stock boot images are easily found, along with the patched_boot.img (that you don't want).
The only issue is that the 2 slots, one will be the most current software you last updated to, the other will be the previous version you updated from. Do you know which one as active and what version it was running? If not, sounds like you'll have to guess.
If you can get one slot to boot you can then probably fix the other okay.

I'd stop flashing roms. Yer bootloader is the problem now, not the rom.

Do I only flash the boot.img file? I don't know if you noticed but the jasmine 9.6.15 is a folder with all the stock images.

If you haven't change system, you haven't flashed any rom to it, on slot a, then yeah, just flash the boot.img for that version to slot a. You should then be able to set that as active (if it isn't already) and boot.

Now i get bootloops. Should I flash system.img too? Apprently all this fault is because you have to type .\fastboot.exe instead of fastboot in powershell.

I have fastboot flashed all key elements of working Android phone multiple times. Can only get to fastboot after boot screen that I have to do manually. Recovery system is toast.... Guess it's back to Poco F1.... Learned my lesson from junk.

Every time you restart back to the bootloader you need to do: "fastboot oem nubia_unlock NUBIA_NX629J" first

if you stuck in the Device is corrupt. It can't be trusted and will not boot and you are in the Chinese or global rom then flash the stock boot image via adb. well I am using a Chinese v2.27 rom with rooted +gapps and then realized that most of the google apps wont work correctly because of the unlocked bootloader. I tried to lock the bootloader via adb then the message "Device is corrupt. It can't be trusted and will not boot" show up. so I try to use adb to flash the stock boot image then it work. first place the stock boot image to the "Minimal ADB and Fastboot" folder which located in the local drive under program file(x86) then run the command
fastboot flash boot boot.img
fastboot reboot

Bud I put so much effort in last 13 hours to no avail....fastboot erased all partitions, reformatted, reflashed to no avail. Right now it just boots loops on Chinese 2.27 boot splash, I do have Chinese recovery though, but the same otg adapter and pen drive that works on 5 different devices, this damn phone won't read it so even that is out of the question. I wipe my hands clean of it, some things just best to put a bullet through it.

No BS, all I did was flash CN 2.27 over NA Global, after a look at the mess it was I proceeded to flash NA Global back.....no TWRP No Root with SuperSU or Magisk. But in fastboot it does say Root=1, so I guess the CN 2.27 rooted it by default cause I sure as hell didn't. One thing that is bothering me while in fastboot unlock bootloader I can't turn Secure Boot off which I believe is why it won't boot system.

all you need to do is to fix the corrupt image so later once you finish the first step of booting to the phone then you can flash to global rom. if you have the cn version 2.27 boot.img then you can download the adb and use the command to fix the phone

Shouldn't have messed with something that wasn't broken. Now you have a nice brick to use as a paperweight. Hope you get it fixed tho. Good luck.

Help| Can't boot

Hi,
I have Carbon ROM with Android 10,
I wanted to flash Bliss ROM, and it says that I need a rooted device,
So I've downloaded Magisk and follow the instruction, created a boot.img and flashed it in fastboot, then I did the same only with twrp recovery & Magisk, flashed it and now it is wiered and I'm not sure what is the problem,
I have fastboot BUT when I try to perform any command, it shutsdown and preety useless, I've tried from PC, if I try from MAC, I can boot into twrp but every operation is causing the tablet to reboot.. So I can't even flash a stock ROM,
In PC, the recognized Android device (When in fastboot mode) I update it's driver to Android bootloader device
Now, fastboot says: "fastboot: error: cannot get boot partition size"
tried:
fastboot flash:raw boot boot.img
fastboot flash:raw recovery twrp.img
How can I solve it?
Thanks !!!

fastboot flash boot boot.img
?

I didn't understand the problem, I think.
You flashed a patched boot.img and your twrp recovery isn't working? Like if you press a button, it just reboots?
