Android stock ROM from Android..
Well, all of you techno wizards here…
There is a common occurrence happening throughout the Android world of users. At any given moment, under no certain circumstances known yet, the Bootloader screen appears without summoning it to. The screen will say "unable to do normal boot" & there is no opportunity for any other option as the screen "Downloading, do not turn off target". There are fixes to this (flashing), now tho… why does a PC need to be involved & monopolize the procedure?
We need a way to install STOCK ANDROID OS FROM AN ANDROID DEVICE. Its all Linux.
Anybody?!

Guys, if anyone has the "can't flash system.img" or " can't load system.img" just use a new version of fastboot and follow the same steps and it will work . i tried it and finally managed to flash stock rom. :good:

how using sdk

I tried to go back to stock rom from CM 14.1 Unofficial following this youtube tutorial : https://www.youtube.com/watch?v=inzG5MLS2y4
I downloaded 2.20.40.196(Latest Android L) but couldn't find appropriate recovery for it.So I searched xda and got one.
I followed this sequence:
1.) fastboot flash recovery (name of recovery).img
2.) fastboot flash boot boot.img
3.) fastboot flash fastboot droidboot.img
the boot.img and droidboot.img being extracted from the stock rom itself.
But after flashing, it shows "continue the fastboot process" in blue and selecting recovery option reboots the phone and brings it back to fastboot.
I CAN ACCESS FASTBOOT MODE,MY DEVICE IS RECOGNIZED BY MY PC.
But there is no recovery.
Kindly suggest what to do in relevance to my post.
Should use Asus flash tool. http://forum.xda-developers.com/showthread.php?t=3452082

cool down buddy. it was for informational purpose only. he was already using commands to do so. i just told him the correct way.
second for using AFT he have to download raw firmware. which is more than 1 Gb of data which will be costly if he is using mobile data to download. as he mentioned he already downloaded LP firmware from asus. with above method. he will be able to install the earlier downloaded zip file without any additional firmware download.
third as he mentioned he was on CM. i doubt installation with AFT might not be successful. he may have to flash stock ifwi and recovery and boot etc...

I don't know what "method 1 and 2" refers to but usually you do it with adb/fastboot. Assuming you have a computer running windows, you need to extract this:
https://dl.google.com/android/repository/platform-tools-latest-windows.zip
- Plug your fully booted phone to your computer with the USB cable.
- From the command line, navigate to where you extracted the files and type:
adb reboot bootloader
- your phone will reboot in fastboot mode, wait for it.
- download and extract latest TWRP binary into the same folder you previously extracted the files : https://eu.dl.twrp.me/whyred/twrp-3.2.2-0-whyred.img.html
- assuming the default filename of twrp-3.2.2-0-whyred.img, type fastboot flash recovery twrp-3.2.2-0-whyred.img
- press and hold the volume up key on your phone and type fastboot reboot
- keep holding volume up until the phone reboot in TWRP.
* Note that if you fail to reboot into TWRP the first time, MIUI will overwrite TWRP with stock recovery and you will have to flash TWRP again.
You have ARP anti 4 rom!
[miui 9.5.22.0 CN.]
You have ARP anti 4 rom!
To flash TWRP you need to temporarily boot it with: -
fastboot boot <name of TWRP>.img
Then when booted, copy the image file to your device, and then install TWRP image to recovery from temp TWRP.
From TWRP, then reboot to recovery to actually use the installed version.
If your sticking with MIUI, remember to flash the script that allows the device to boot with TWRP, or use a TWRP that includes it.
WARNING: - DO NOT Flash firmware's or roms lower than the version your on, or you will brick your device.

NO RPMB (how to install TWRP, a new ROM and using Magisk)

Hello, I have sent my phone to warranty and after that I received a phone with NO RPMB and after many frustrations I found (with help of many users and forums) how to workaround this..
To start:
Download boot image from here
Download twrp from the official website
Change the name to boot.img and twrp.img and put it in the platform-tools folder
Open the terminal there
Download your favourite rom
Enter fastboot mode on your phone
!!!!After this you will loose all of your data!!!!
Paste this to the terminal
fastboot oem unlock
(select yes on your phone)
fastboot flash boot boot.img
fastboot flash recovery twrp.img
fastboot format userdata
fastboot format cache
Reboot to recovery (if it doesn't enter at the first time enter download mode again and restart to recovery)
After that you have twrp and can flash every rom.. yay!!!
Wipe everything.
Copy the rom zip to your phone using MTP
Install your fancy new rom
If you want to install magisk:
Install the magisk manager.
On the app select install and select patch image file. (it will create a new boot image already patched)
After that install the new image (patched_boot.img) using twrp
Do a clean instalation of your ROM (recomended) or a Factory Reset first
Reboot to twrp
Select install
Click in install image
Select patched_boot.img
Select install to boot partition
Reboot.
Install magisk manager and do the sugested setup.
You now have magisk working
Thanks to all the users that helped me!!
I had real trouble getting twrp to work the last time I tried this a few months ago. Followed the steps here and am now on pixel experience with magisk. Thanks!
Hello, im in the same situation of NO RPMB. This procedure will permanently lets have bootloader unlocked?
About Magisk, i can install it in usual way once im in the recovery? (I mean download latest stable version for Bullhead and flash via TWRP).
Thanks.

Click to expand...
Click to collapse
My bootloader is still unlocked after following this guide
For Magisk:
-Install your custom ROM and boot it up (without root)
-Then extract the boot.img from the ROM zip file and save it on your phone storage.
-Install the Magisk manager apk
-In Magisk manager, select install Magisk> choose the patch boot image option and -Select the boot.img you previously saved.
Once it's done, reboot into twrp and flash the patched boot.img. When you reboot Magisk will be working.
I've had no issues with my bootloader, even after an ota update for pixel experience.
Thank you, i will try it.
Another question. I never tried dowload mode before, as i read in other post i should Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb that's already connected to pc, right?
When in download mode i can fire up fastboot commands like im in bootloader mode?
So then after do last command fastboot format cache i can reboot to recovery from terminal using adb reboot recovery or i can / should do it from device?
About twrp it's ok to use the latest 3.2.3.0 official version or the 3.2.1 4core version from here as someone suggested from Reddit? https://forum.xda-developers.com/nexus-5x/development/recovery-twrp-3-2-1-4-core-t3796656

The official twrp works for fine for me, haven't tried the 4 core version but it can't hurt to try if you need it.
Power off your phone then press and hold volume - and power to enter bootloader, then connect to your pc and follow the steps in the OP
So i have to enter in bootloader mode? At point 6 of OP there is written to enter in the download mode, this makes me confusing.
Can anyone explain me latest 2 commands why they are needed?
fastboot format userdata
fastboot format cache

This thread is fairly comprehensive;
https://forum.xda-developers.com/nexus-5x/general/moto-nexus-5x-sticky-roll-t3207487
Holding volume - and power takes you to fastboot mode (download mode essentially), theres also an option to reboot into recovery (selectable using the volume keys.)
Formatting user data and cache is necessary prior to installing a new rom (especially if moving from stock). You lose all data (back up first!) But a clean flash is the best place to start.

Thanks for the explanation but for installing a new ROM usually you can do factory reset directly in TWRP, plus doing all the wipes, this should be enough.
About fastboot mode and download mode, they are completely different, fastboot mode: vol down + power, download mode for LG: Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb.
My question is what i can do in download mode? As OP says after entering download mode open terminal and use fastboot commands.

You need to use vol- and power to go into fastboot mode then connect to the pc. As for userdata and cache, if you don't clean them when coming from stock you will have issues (your data will be encrypted if you're on stock?). As I said this guide worked for me. The op was talking about fastboot mode in the 6th option (also there is much more information in the thread I linked above)
sorry for the confusing i wanted to say fastboot mode..
i knew the thread that you are saying but most people doesn't want to search so I made a little thread only with the needed parts..
I use it myself so I have a place to remember all the steps when I need to change the rom to a new one or when I make experiments and brick my phone XD
If anyone know anything else that should be in here just say, I really want to improve the post

your device will always be locked this is a workaround to get twrp, new roms and magisk while it stays locked..
with twrp usable it won't matter if you are locked or not

Thanks for the answer. You mean that now I have twrp, I can flash custom Roms with my bootloader locked without any issue?
Envoyé de mon ONEPLUS A3003 en utilisant Tapatalk
Yes if you have TWRP you can install custom ROMs, custom Kernel's, magisk, super su, etc..
the locked bootloader only prevents you from using fastboot commands like the one needed for installing custom recovery
Now that you have TWRP you can use it for everything
Hello everyone, I also have a nexus 5x with motherboard that has been replaced under warranty and unfortunately I can't keep the bootloader unlocked.
I tried the procedure you have indicated, but at this point there is the problem, because after inserting the boot.img and twrp.img inside the phone, then when I go to do the unlocking procedure with 'fastboot oem unlock (select yes on your phone) 'in practice the memory is deleted on the phone, so I lose the previously uploaded files, and therefore I can no longer continue with the flash procedure of boot.img and twrp.img because they are no longer present in memory.
I hope I made myself understood, maybe I am wrong, or is there a way to solve this problem?

Hello everyone, I also have a nexus 5x with motherboard that has been replaced under warranty and unfortunately I can't keep the bootloader unlocked.

fastboot is for the files on your PC not your phone
you need to put the files inside of platform-tools and then open cmd inside it and use the fastboot commands
fastboot will take the files of your PC
Hello, thank you for your information, since I haven't done modding on phones for a long time, I didn't remember exactly the procedure with fastboot and therefore I didn't understand where I had to put the files, but in the end I did it.
Thank you

Why is a custom boot image needed? I don't want to root.

No OS is installed. Moreover recovery cannot be accessed. Nor can flash it via adb.

Previously I was using Ressurection Remix treble rom which is based on android 9 pie. I went to TWRP and wiped the OS. Then I tried to install a new rom called Dot OS. But it showed error 7. So I flashed Vendortofactory zip within twrp and without rebooting again into TWRP I flashed a new TWRP image within TWRP by selecting Recovery mode. After that I cant boot into TWRP and as already my OS is gone I also cannot boot into any system. Moreover my device is not getting detected in my PC. I cannot install TWRP by writing commands in cmd, while the phone is in fastboot mode as the device is not getting detected in my pc. Really it is urgent. I will be glad if someone helps me. Thanks in advance.
What is the present booted state of your device? Are you in twrp, or bootloader. Most of the time you can keep on pressing the power button. When it boots into a message about unlocked bootloader, press volume button to select recovery and it will boot into twrp
You should be able to boot in fastboot mode without recovery nor os, maybe your drivers are not working on windows? Try different usb ports, check if the display says "bootloader" or something. If nothing works try the usb shunt, this device is literally 'unbrickable' if it's working properly.
Watch this video(https://www.youtube.com/watch?v=DexLELi04XY) and then you will be able to detect your phone in your pc in qcom 9008 mode , then use qfil to flash ZUI firmware ,there are plenty of tutorials on the internet for that ,then follow the proper procedure mentioned in DotOs thread for flashing the new rom .
Hope it helped .
If you don't want to flash the firmware and all long process just follow the following steps
Enter in to the boot loader make sure you installed all the drivers in to pc then open cmd windows in adb fastboot folder and enters the following cmd into the cmd
Fastboot -i 0x2b4c devices this will detect your device
After that enter
Fastboot -i0x2b4c flash recovery recovery name.img
And boom you are good to go flash the rom of your choice and enjoy
For this process you need following files
Adb and fastboot devices
Drivers of zuk z2
Latest recovery and place revovery image file into the adb and fastboot folder if you are confused about anything pm me i am not the expert but i faced simillar problem and solved by this method

This assumes u have upgraded bootloader to 4.4 kernal.
U can still boot into twrp.. When the phone is booting up press vol up key and select recovery.. From there boot into twrp. There select f2v or v2f .. Then flash twrp which u want to flash.. Reboot to recovery.. U will get promp no os installed.. Ignore and reboot to recovery . Then again d9 f2v or v2f depending on what rom to install.. Again reboot to recovery... Then flash rom of ur choice.
This procedure is needed when changing from vendor to factory and vice versa.

Oppo A83 [CPH1729] TWRP RECOVERY

⚠Warning: This is not official TWRP, use it at your own risk!!!
Data will be erased. Back up if neccessary
This device is kind of weird so to flash twrp you need these things:
1. Prepare materials​
Install driver so as to have access to preloader (Just install automatically and no need to do anything in device manager)
This software to access to preloader -> fastboot (fastboot is somehow not available via adb methods) Enter fastboot
This tool for flashing
2. Unlock bootloader (need testpoint, python, git (optional) - you can search on google)​
Use this tool - go to this section. Follow guides to unlock bootloader (remember to use testpoint not hardware buttons)
3. Enter fastboot mode​
Use latest MTK META Ultility tool
Select Reboot Fastboot Mode in BRom section
Hold volume down button. While holding connect it to your computer
*Now your phone is in fastboot mode​4. Flash​
Open platform-tools folder in Downloads folder
Shift + Right click then "open command window here"
Input these commands into cmd
fastboot flash boot drag twrp file to cmd
fastboot flash recovery drag twrp file to cmd.
fastboot reboot. Swipe to allow modification in twrp (to make sure that stockboot wont replace twrp). After that reboot to recovery to make it installed on your device permanently.
Now your recovery is ready to flash file you can push stock image file to your root folder using adb command: "adb push. Drag the stock image file. /" (Because Decryption right now doesnt work on my device yet)
Enjoy
*Sounds crazy but it is required to make sure twrp is installed correctly​*If successful, when you power on, you will get a red section on top of your device. If you want to recover to stock recovery, flash the recovery.img below.​*Also, if you want to make your own twrp, you can try recovery.img below.​
Also thanks SebaUbuntu and Mofadal El-Tayeb (مُفَضَّل) for awesome apps
