[Q] Gnex Brick Mount Fastbood Write Fail help :'(

Hi everybody,
ok I will try to make this short
I have an experienced user level ROM, recovery, boot, ..
My phone is BRICKED! Is it?
AT THE MOMENT:
- I get into fastboot mode
- I get into odin downloading mode
- I can't start in recovery mode
- I can't start bootloader mode
- I have a connection with a laptop (win XP, as win8.1 didnt work for me)
- The computer can communicate with the phone in fastboot mode
- The computer cant communicate with the phone in Odin mode (at the moment Odin PC SoftWare doesn't recognize the phone)
- I am sure the drivers are installed correctly now. Thanks to the guide with fully stripped drivers.
- Using different, multiple different, no thousand different methods I tried flashing the stock OS (Yakju 4.3)
- I like SkipSoft Android ToolKit (Although I used fastboot and adb commands, I find the toolkit to do the same thing..)
- I always get an Error, when the process of flashing starts.
> PC says : Error
> Phone (in fastboot mode) says: FAILWrite Fail
INTERESTING:
- While I still was able to get into Recovery, the phone couldnt mount the sdcard (=> the internal drive)
- Some of the methods I use make the phone CRASH
> means the screen stops at its position and slowly turns completely purple
- The phone power button doesnt start the phone, to get the phone doing something at all I have to trick it:
..> I plug it into the wall charger
..> I take the battery out
..> I put the battery back in
..> I wait
..> I can get into 3 routines:
^Normal starting routine (of course stuck at google start up, since no Rom is installed)
^fastboot mode (VOL + & - & Power)
^odin mode (VOL - & Power)
..> Then I can just plug the USB cable into the PC
- 2 days ago I had (every single version) of Odin PC Software recognizing the phone (phone was in Odin mode), but it also failed after trying the recommended and unrecommended settings. Ended with an error message.
HOW:
I left my phone overnight in the car (Temp: -2 deg C), while Im sure spotify and maybe other consuming apps were playing.
Next day, my phone battery was empty and I couldnt start my normal ROM. (I had Slim Rom installed)
It was stuck at the "Google" start up display.
First intentions showed that it might be more than just the Software :/
Many days and so many hours of work, research and reading in forums, I decided to take a shot and ask here.
I appreciate everything xda-members have done for me already. Though I never needed to register for my earlier questions.
Phone data:
Product Name - tuna
Variant - maguro 16gb
HW version - 9
Bootloader Version - primemd04
baseband version -
carrier info - none
serial number - -a3c208 ***
signing - production
lock state- unlocked

BUMP!!! I have absolutely the same problem!! I can access everything, i enter the recovery trying to WIPE every single thing data,system,cache,storage etc.. but it seems it doesnt work. The information stays. I tried to "softbrick unroot & stock" with a nexus kit, everything seems ok, but after it finishes installing, it boots up on GOOGLE and after 10-15 min it starts to BOOT MY OLD CUSTOM ROM THAT I HAD BEFORE, after another 15-20 min it finally boots up and the system is EXTREMELY choppy and unresponsive and after a few minutes it restarts itself. I tried ODIN and I faced the same problem, it goes well to ~45% and then it freezes, and after a short delay odin gives FAILED. I tried several more things that i found on the internet and xda but nothing helps. Probably a corrupted partition or something. THE DAMN STORAGE DOESNT WANT TO DELETE ITSELF FFS!! PLEASE IF YOU KNOW ANY FIX/ALREADY FIXED YOURS PLEASE HELP!!! I need my phone!

can you give us more information about the error message?

Similar, only difference is with fastboot i can successfully flash system.img but nothing happens. With odin it fails at around 45% and then freezes. Only difference is that i cannot boot to old stock and i dont have this pulpish problem. I simply reboot on my old custom ROM configuration with all my last known icons widgets.. but the phone is choppy and unresponsive as hell.

I only get an error without any further message after flashing any of the images...
Any idea anyone? Isn't it some hardware issue?

Noo man i dont think its hardware problem, for me it all happened when my phone suddenly restarted itself and after that it bootloops forever and i have those problems

Anyone?

does erase work?

yes

can you get into recovery?

ka

how do you know that erase works, I mean that what you erased has really been erased?

One of the erase command in the toolkit was succesful, I guess. But I will recheck every error or successful message later tonight.

still NOT working
2 months have passed and I was too busy with other things.
now back to it. the problem hasnt changed.
i try fastboot flash command:
[fastboot flash bootloader x.img]
- in Computer Terminal: 'FAILED(remote:Write Fail) '
- on phone: ' FASTBOOT STATUS - FAILWriteFail '
any idea, please?

Solution for Hard Bricked LG G4 (9008)

Hi guys,
Some people including me faced Hard brick issue with LG G4, which has now two solutions. the first is temporary, i discovered it and it involves using an SD card flashed with Original EMMC dump ( i tested it with H815 ands H811) , the second needs advanced hardware, equipment and soldering skills ( JTAG) .
The solution that i want to explore is trying to revive the phone with the SD card.
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h811-9008-qualcomm-t3456417
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h815-9008-qualcomm-t3452853
The H811 dump that i made has TWRP recovery and unlocked bootlloader, so if someone know how to help that would be awesome.
How ???, its very simple. I dont have very good UNIX architecture skills , but if the SoC successfully booted from the SD card. We could see if it detects the EMMC memory ( with parted or with LS command). I personally Tried to brow /dev/block directory from TWRP i hoped to find MMCBLK1 or something but that was unsuccessful , im pretty sure the TWRP or the Soc Does not mount it automatically .
I really dont know How , but i'm very Sure that there is a Solution headed that way , So if some one is Good with Unix architecture and can find a way to soft Flash the EMMC from TWRP ( installed in the SD card ) it would be very Nice

hi,i tried the sd card method...it boots but immediately gives me secure boot error (1006).
i have an h815 bl locked

Hello
I have LG H815 and have bricked. I have installed wrong firmware so it is brick now.
I try new tot file with QPST . but it says fail what s wrong with me?
My computer is win 10 64 bit

You can fix fastboot mode with this way.
1. First you need to download stock rom that your phone supported. extract laf.img file from rom and copy it into fastboot directory
2. download LG Flash Tool and make it ready
3. open flash tool and load firmware and dll that support your model.
open command prompt and make sure you in fastboot directory where the fastboot and related files are stored.
Run following commands.
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot

Hurry up, now you need to start flash with lg flash tool, if device does not start into download mode. remove battery and insert again, press and hold Vol Up btn and plug USB cable it will boot into download mode. and your device com port should be 41, if not change it in device manager. and start LG Flash tool to load stock rom. once it finish loading rom your device will start and will show you factory test 1, 2, or 3. if it stuck there more than 3-5 minutes. reboot your phone. now you will have welcome screen.
I hope this will work with supported models.

lol, when you see a screen with 0% and a usb connected image, that mean your battery dead
why not just try to charge your phone? or replace a battery?

Hello, well after what happened I thought the same and went to buy another battery and when they tried it did not work, I repeat, not fastboot, no logo, no recovery, only a small vibration without screen, it is not detected by the PC in any of its modes as dead, the detail is that this happened after restarting when I had flashed bootloader N, rom V30, magiistic, I gave it restart and it did not turn on again, so I discard that it is hardware .
I think the problem was that I flashed the bootloader with full aboot, that gave me hardbrick I was told in a forum in Spanish I leave the link I hope you help me thanks

Hey MichaelCV
I have exactly the same problem with my LG G4 H815p. I was running [ROM][H815] H-ROM G4 NOUGAT [v29a] _ LG G4. The phone was up and running and last night I flashed the "LG-H815_29a_Modem_and_Bootloader.zip" to try resolve an issue I was having with the mobile data indicator not showing. I flashed the zip in TWRP, rebooted the phone and now it is bricked. I have exactly the same symptoms as you. Windows and FWUL does not see the phone, no matter what combination of keypressed etc that I try.
Lets hope we find a solution here for it.

[help] ZE551ML crashes, TWRP freezes, no connection in xfstk downloader

Hello all,
I'm stuck in different guides on what to do next.
Problem: Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13.
Also had charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.
Tried:
- Factory reset in TWRP -> didn't work (the occasion I did get into CM13 it showed the setup again, so the reset actually went through, but loops still exist).
- When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
- When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots
- Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC.
-> Problem: Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
- Another problem: When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.
So now im a bit stuck on what to try next to solve everything and get myself back into CM13. CM13 has ran since Feb '16 and have been a happy user since then until now.
Thanks for reading!

The simplest solution may be to flash back to stock and start over. If the phone doesn't behave properly on a stock ROM, there could be a hardware problem.

Hi there , in TWRP select reboot then power off .
Enter bootloader via buttons after 10 seconds being off !
Enter bootloader - power and vol + , when in bootloader if on LP -- flash raw with AFT (asus flash tool )
If any probs with above , you might have to fastboot flash stock recovery and boot to recovery if/and a , try raw if on LP with AFT or b, sideload stock firmware you flashed stock recovery for.

Thank you for your answers! Last hours been trying to flash the stock ROM back. However, when getting into bootloader, adb devices and fastboot devices don't show the device. Or it even freezes and gets into reboot loops again. So this is why I'm stuck, nothing seems to be working from all the guides and things I'm reading.
So precisely:
- Power off bootlooping device by holding power button
- Power on by holding PWR + VOL UP
- When vibrating: release PWR keep holding VOL UP
- Now i'm in bootloader?
- Connect USB cable to computer
- type adb devices, shows nothing.
So what can I try to make connection?

- Now i'm in bootloader?
- Connect USB cable to computer
- type adb devices, shows nothing.
@j4y_ha .................in bootloader

What ifwi version number in bootloader ?

The bootloader in shows the following:
IFWI version: 0094.0173
SERIAL_NUMBER = F8AZFG0152** (couldn't read the last 2 digits as the device rebooted again). Also sometimes the SN shows 012345689ABCDEF.
I've much trouble keeping the device in bootloader. Last tryings it keeps shutting down after couple of seconds in the menu.
EDIT:
So far the device seems to stay in bootloader mode now. I can cycle through the options normal boot, recovery etc. Below the screen it shows Continue the fastboot process in blue text. I've inserted the USB cable but have been unable to get "fastboot devices" to show any device. ASUS Flashtool also doesn't do anything.
I'm going to try to find a micro SD adapter so I can try flashing stock rom in TWRP from the phone itself (would that be something that could work or is this phone fubar?)

@j4y_ha
Do not attempt to flash stock rom in TWRP ! You will brick !
Flash a custom rom in TWRP only- not one with a mm bl version
You have LP
PLEASE
Follow my first reply to you

I have MM not LP.
I don't understand your reply correctly I think so here is what I think you say?:
I should obtain LP rom for ZE551ML
Next, enter bootloader via buttons PWR & VOL UP after 10 seconds being off !
When in the bootloader, - power and vol + (short press or long?) , when in bootloader ->
I connect USB to computer, flash the file using AFT if I make connection. -- flash raw (raw = LP ROM from ASUS) with AFT (asus flash tool )
Thanks again for your help

@timbernot I'm unable to make connection. Fastboot also most of the times freezes and goes to black screen. What could I possibly try now?
Sorry I thought CM13 was MM but then I'm on LP still haha :good:

I'm taking wild guess here that you got wrong TWRP recovery installed somehow or something from M causing all these problems , when you get into bootloader again..Scroll to and select reboot bootloader and fastboot flash stock recovery for LP version you was on .
Then , I guess your problems will be over , where you will be able to flash raw in bootloader or in stock recovery , adb side load the firmware

Thanks for your quick anwer. Will try to get through it haha :good:

DUDEE
that's not a problem.. THAT's like 20 different problems... I bricked the living crap out of my zen the day I bought it (because me = smartypants did not know that the MM boot unlocker is nonexistent so I just tried to root and update from my head using older techniques) and... the XTS tool thingy fixed it..
Don't get me wrong, i want to help but this is the problem that I feel little frustrated with..
Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13. ## (but it boots sometimes and goes into TWRP, so you have an easy fix to just revert to stock lollipop... why haven't you done that? You sound like you know what most of this stuff does...
Charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.
## how do you connect this battery issue to your occasional bootloop? Check hardware or firmware and definitely use different threads.. there's no way these are all part of the "same problem"...
When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots
## Same answer as above - this is unrelated to #2 and unrelated to #1 - is your TWRP the correct one? I mean... did you just maybe flash TWRP version 4000 Modified Alpha for Google Glass??? LOL
When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
## Is D2W there? "DoubleTap2Wake" ? Are you sure you have a good touch? (this maybe 20% sounds related to your TWRP touch going crazy..)
Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
## There's this awesome invention called DRIVERS... and we're lucky in this case (cuz I bricked an hour after I bought it) because Intel PC + Intel Phone = Yay... There is even.... a very specific "INTEL ASUS WINDOWS DRIVER" file... from the INTEL AND ASUS WEBSITE... or maybe your USB CABLE is f**? My point is... another unrelated issue where it sounds like you've not even tried it properly before complaining.. I like helping people. I don't like when people refuse to try or they skip the actual study-notes to do it... I used the EXACT same guide to unbrick and it worked in 2 mins... I'm on a 2007 Laptop which overheats if I use 4 tabs... how am I able to follow the exact same guide on a brand new "FULLY BRICKED" phone... it literally would vibrate after trying power button for 5 mins and be stuck in a "blank black screen" for hours and hours... No twrp no nothing.. and I did it - why didn't you? Same guide man...
When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.)
## Try again. Sometimes people accidentally hit power to early.. or whatever.. It's not a MK2 Fatality.. don't force yourself to get it exact.. Let the menu pop up... just wait a second and scroll up/down just to see if that works... then scroll to Boot-Recov and gently hit power+vUp.. should be fine.. otherwise just .. literally try 10 times.. it WILL work.
Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC
## Nope.. TWRP is like Bret Hart. It isn't unstable. Not for LP not MM not for N. Not for Stock Not for CM Not for AOSP. You *wanted* to do what you should have done right at the beginning but you didn't get that done properly (see below)
Essentially you have 8 different unrelated issues (and the biggest one is not reading guides, not trying hard enough and just thinking that people like me sit around and get paid for this)... and want ans in one place w/o just doing the simple thing of going back to everything stock...?? *it's just annoying cuz people who want to help will feel like.... others don't even try simply because we exist and have desire to help...* - I am not trying to offend you but I hope you get my pov.
Do This EXACTLY
#Buy a cable. Borrow a cable. Whatever you do be 1000000% sure the USB Cable is fine
#Install Intel Asus Android drivers from official EXE (google it... don't add new post for that link)
AND THEN
Follow the same Unbrick guide word for word *but* just pay close attention to these:-
IntelSeC Driver + device detected even if OFF (start>devman>showall>intelsec
In the official unbrick utility make sure you're on the second tab at the bottom
In settings check that your device flag is 0x08..... whatever instead of the default 0x000
Back in the *second tab at the bottom* (i don't remember exact name but it's in the guide) -- put the right files (mentioned in guide) in the right boxes.. (mentioned in guide) and remember you ONLY need the DVFWthingy... + TOKENthingy + IFWthingy
Plug the Zen in... hear the "da-dumm" sound... keep looking at the Unbrick tool.. and the moment you see Device Detected = 1 you hit install/start...
AFTER that is fully done *(and if you fail don't post just repeat from scratch)... I don't personally recommend Asus Flash tool it was acting dodgy for me but instead grab the RAW Stock... Rename it to zip.. open it and grab the img files and fastboot flash the fastboot droidboot.img + splashscreen splash.img + boot boot.img + recovery recovery.img
If you've followed all that from the guide and double checked what I've put up there.. you should be fine if you just fastboot reboot bootloader... and go into stock recovery... install zip/update and put your stock OS in there..
Done.
Just please take my advice and don't skim through guides, don't think you don't need to read something, don't click stuff without double checking every line from guide, print it out on PAPER if you need to.... but please don't post like this... and don't use different guides or you will be stuck (as your heading stated..)
Forget everything you knew. Close all other tabs and use this guide thoroughly for Reference:-

Wow @ryankabir
one step at a time hey
xFSTK is used to bring temp bootloader to hard bricked devices .
He has stock LP bootloader and all avenues to repair should be explored first
If anyone needs to unbrick , there is a thread in my signature below ,shows how to go from complete brick , to restoring serial number and into system within 15mins

Thank you for your thourough answer Ryankabir! Much appreciated. My answers are below. I will try your suggestions soon.

Yes I do know what I can do with it, but it just so complicating as there are different factors like the loops, not being able to get connections with USB. I mean, it is not totally bricked since sometimes I can get into TWRP or bootloader.

Well, since the phone worked fine before the battery issue, there is some sort of link between the issues I would think. Maybe I've broken some hardware during the battery removal or did the booting into charging mode and on/off continously corrupt some memory leaving me with weird crashes & loops.

Although I'm not sure if I have the correct TWRP, it did flash CM13 correctly back in FEB 2016 and haven't found a need to update it ever since as it worked fine during the occasional update...

When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
## Is D2W there? "DoubleTap2Wake" ? Are you sure you have a good touch? (this maybe 20% sounds related to your TWRP touch going crazy..)

No, D2W is not there. The phone is totally unresponsive to the power button as well as D2W. When in TWRP the touchscreen functions fine until it freezes at some random moment.

Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
## There's this awesome invention called DRIVERS... and we're lucky in this case (cuz I bricked an hour after I bought it) because Intel PC + Intel Phone = Yay... There is even.... a very specific "INTEL ASUS WINDOWS DRIVER" file... from the INTEL AND ASUS WEBSITE... or maybe your USB CABLE is f**? My point is... another unrelated issue where it sounds like you've not even tried it properly before complaining.. I like helping people. I don't like when people refuse to try or they skip the actual study-notes to do it... I used the EXACT same guide to unbrick and it worked in 2 mins... I'm on a 2007 Laptop which overheats if I use 4 tabs... how am I able to follow the exact same guide on a brand new "FULLY BRICKED" phone... it literally would vibrate after trying power button for 5 mins and be stuck in a "blank black screen" for hours and hours... No twrp no nothing.. and I did it - why didn't you? Same guide man...

Yes I know what drivers are :good: - I've tried IntelSoc, Intel ASUS etc... all drivers that are somewhere mentioned I have installed. Before the charging problem I was able to connect the phone and access files fine as well.
ryankabir said:
When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.)
## Try again. Sometimes people accidentally hit power to early.. or whatever.. It's not a MK2 Fatality.. don't force yourself to get it exact.. Let the menu pop up... just wait a second and scroll up/down just to see if that works... then scroll to Boot-Recov and gently hit power+vUp.. should be fine.. otherwise just .. literally try 10 times.. it WILL work.

Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC
## Nope.. TWRP is like Bret Hart. It isn't unstable. Not for LP not MM not for N. Not for Stock Not for CM Not for AOSP. You *wanted* to do what you should have done right at the beginning but you didn't get that done properly (see below)

TWRP is indeed fine and stable! However, it freezes and reboots my phone so in my particular situation it is currently not stable. Therefore the need to completely wipe the phone and start from fresh.

Appreciate your POV. I know how it feels like if people ask for help for something they could have read easily somewhere. I'm thankfull for all the guides that people have written on here! I'm asking for help because in my situation the guides are not working and would like to have a full clean wipe of my phone and fix all possible software issues before trowing away the phone because of hardware fault.
ryankabir said:
Do This EXACTLY
#Buy a cable. Borrow a cable. Whatever you do be 1000000% sure the USB Cable is fine
#Install Intel Asus Android drivers from official EXE (google it... don't add new post for that link)
AND THEN
Follow the same Unbrick guide word for word *but* just pay close attention to these:-
IntelSeC Driver + device detected even if OFF (start>devman>showall>intelsec
In the official unbrick utility make sure you're on the second tab at the bottom
In settings check that your device flag is 0x08..... whatever instead of the default 0x000
Back in the *second tab at the bottom* (i don't remember exact name but it's in the guide) -- put the right files (mentioned in guide) in the right boxes.. (mentioned in guide) and remember you ONLY need the DVFWthingy... + TOKENthingy + IFWthingy
Plug the Zen in... hear the "da-dumm" sound... keep looking at the Unbrick tool.. and the moment you see Device Detected = 1 you hit install/start...
AFTER that is fully done *(and if you fail don't post just repeat from scratch)... I don't personally recommend Asus Flash tool it was acting dodgy for me but instead grab the RAW Stock... Rename it to zip.. open it and grab the img files and fastboot flash the fastboot droidboot.img + splashscreen splash.img + boot boot.img + recovery recovery.img
If you've followed all that from the guide and double checked what I've put up there.. you should be fine if you just fastboot reboot bootloader... and go into stock recovery... install zip/update and put your stock OS in there..
Done.
Just please take my advice and don't skim through guides, don't think you don't need to read something, don't click stuff without double checking every line from guide, print it out on PAPER if you need to.... but please don't post like this... and don't use different guides or you will be stuck (as your heading stated..)
Forget everything you knew. Close all other tabs and use this guide thoroughly for Reference:-

I've tried your guide but I still have been unable to get a connection with ASUS Flashtool. The phone does keep itself relatively stable in bootloader (don't know what fixed it) - I am able to cycle through normalboot, recovery options etc without it crashing. The bootloader shows "Continue the fastboot process". I have tried different drivers, while rebooting between install/uninstall of drivers.
Thanks again all for the help

Do not stray from this guide.
Stick to it and you will be more the wiser when you have finished .
1 boot to boot loader ...scroll to 'power off ' and select it.
2 Connect your phone to wall charger ...let it charge till full.
When that's done , we ready for next step

Mmbl came about around July 16, he run cm 13 Feb 16.

xFSTK is to gain temp Boot loader.
He gets recognised in fastboot.
He can flash stock recovery .
He can sideload .

But
Can he ?
That's not sn ide btw

Well I'm not gonna dig too deep into the twrp touch issues (there could be conflicting drivers or even something weird i noticed in twrp302 anything below 20% batt (or if batstats corrupt) then the touch goes craycray.. so lets ignore that..
this thread is getting too heavy i won't have time - so - you can always backup ur data partition so no worries there.. nothing to lose..
one problem at a time.. as I said in first post my phone was bricked much worse i had mismatched fastdroidboot and bootimg and after pressing power on maybe 4-5 times.. it would only turn on once.. sometimes on and immediately off... sometimes on stuck on logo.. sometimes on and no logo but screen is black (corrupt splash)..
so lets just try to go baaaaaack to the futureeeeeee ... Ok I found the script I made (after 8 hours of trying EVERY combination from different guides I just took individual components and made my own.. ) -
I'm writing this in a hurry so please use my first reply to get the XFTS Ubrick Guide for the Files + get the LOLLIPOP One Click BL Unlock + Lollipop Raw image... Their Guide wants you to use Asus Flash but that program failed me every time... so I have got a differnt way to do it..
I'm copying this directly from my own script (so you can change if any paths/names different)... but do not change the order or sequence
Using OneClick (keep the unlock1234 files saved separately for later use)...
If you have these unlocked I just say do it again anyway - no harm...

Question How to fix Poco F3 stuck in Fastboot?

I recently installed ArrowOS to my F3 and everything went well. Then I tried returning back to MIUI, flashing it through recovery didn't work so I used the MiFlash tool. Unfortunately I accidentally chose the Erase all and lock option but I exited the application halfway. Now my phone is stuck in fastboot and doesn't turn off, holding down the power button only resets and returns to fastboot. I tried reflashing MIUI both in fastboot and Miflash but both failed. I also checked if my phone was still unlock through MiUNlock and said it was unlocked, though the unlock icon isn't present when the phone is resetted. Is there a way to fix my issue, I'm really concerned if this will permanently break my device and possibly burin in the fastboot logo on my display. Any bit of advice and help is appreciated.

Lol , help you how?
Guess what's wrong ?
What error? Post everything first
Your phone is not locked if you removed it before end

Its just stuck in this step in both keep data and wipe all data.

Looks like usb cable contact issue to me , could even be locked if your halfway is 10min into flash or something... It also happens when you flash consecutively without rebooting
Check pc usb port , plug into usb 2.0 port
Check cable , use original cable
Reboot phone before every flash attempt
If one firmware doesn't work download and try another one ( Only if it spits out crc error : step 7/9 , any other error or lower step like 4/9 re insert usb cable into phone and don't touch it , the phone is losing contact ). Crc error is a real bich , you are on your own figuring that out , don't even bother with guides like removing crc check.
You are failing at the very first step , open mi flash logs from it's dropdown menu and either send screenshot or zip the whole folder and attach it here

1. Make sure ur device is unlocked bootloader
2. Download and extract this file https://t.me/PocoF3ID/494392
3. Double click hentai_go_away.bat it will help you out of fastboot and get you to twrp. From there u can install whatever rom u want.

Reboot phone by holding power button for 10-15seconds , hold power down as well , don't let it try booting up at all.
Your best bet is to boot it straight into fastboot , not let it fail the boot and enter fastboot by itself

Reboot phone , remove usb cable from phone , rotate it 180° and plug it in again. Don't touch the phone at all after that. Move away from pc table , click start and watch it from distance.
Fastboot commands are not going through correctly from what I've seen in the logs of one folder.
Send screenshot if it errors out again, and logs...
Honestly idk what to tell you , bring the phone under light and inspect the usb port, same with pc port and cable , if all is good keep rebooting the phone and plugging in the cable in and put after every flash.
I had the same issue before , my usb port had water dmg and would act the same way. Flashing fine one time , and other time erroring out in many different ways.

That's not the log file for error above... But I found similar one in folders above.
Clean the ports before you sleep... Power off everyrhing , phone pc , remove usb cable from charger and clean them all with cotton - if you have 97℅ or higher alchohol you can soak the cotton in it and clean the ports.
If not just send it back to service... They will prolly replace your motherboard if the flashing fails on their end as well , usb port will only be replaces at the very end of their troubleshooting.

Question No valid operation system could be found on G10

Hello There
Just tried to reset the phone from a colleague(forgot his pattern and didnt use his G10 since december 21) and stuck with TFM tool on no command.
Tried every combination with power and volume up but couldn't go further.
With luck after one night of trying the fastboot command on CMD finally found the phone.
First command I tried was fastboot reboot fastboot(found the command somewhere here G10 forum).
The device now wont start in fastboot and start immediately with the AndroidOne logo and afterwards a big red explanation mark with the message:
No Valid operating system could be found.
The device will not boot.
Appreciate any help
Thank you!
Pete

Hey Pete,
I know it's a little late, but I'll put this here just in case you or anyone else needs it later. I got the same error after reset and fixed it by changing the active boot slot.
boot to fastboot
from command prompt/terminal: fastboot getvar current-slot
command will return something like:
current-slot: a
Finished. Total time: 0.002s
In this case you would want to change slot to 'b'
fastboot --set-active=b (if the above says 'current-slot: b', then use --set-active=a here)
fastboot reboot
Then go get a drink or something, this reboot is going to be SLOW.

Dear Experts,
I am having the same error as Pete explained in the beginning, the real problem is I can't get into recovery/fastboot mode by trying different key combinations found in the internet. When I try the combination/ connects usb to PC it shows the error and restart everytime. Even tried to flash stock rom using sp tool but it's not detecting in PC either. Tried a heap of MTK drivers. Tried Test point method. None of these seems to work. Could any super humans among you help me please.
Model - Nokia G10, TA-1334
Thanks in advance..

After a week's research, found the solution and brought back my phone from death. The problem was not the drivers. it was me. Tried the test point method in wrong way, need to set the connection from test point to GND first and then only connect to PC. Also make sure there is at least one program awaiting to be connected (Eg. MTK Client/ MTK Bypass tool).
1. Disable the secure boot.
2. Use SP tool to flash the ROM (Trust me there will be errors. Lots of errors, but it can be sorted with some deep google search).
3. Make sure the test point connected to GND all the time while flashing.
You can do it. Finally, my problem shrinked to the invalid IMEI. will sort it out.

You should have back up the firmware before doing anything.
Please try to get the phone in fastboot mode.

I did not make the backup. The combination of buttons to get the phone in fastboot mode does not work for me. All it does is reboot.
