Stuck in Fastboot Mode (pls help!)

Hey,
I had problems with the phone and support told me I should flash it. So when I wanted to "flash system.img"
it showed me: Data Transfer Failure (after 48secs)
and when I type in "fastboot devices" now, the name of device now only shows questionmarks: "?????????? fastboot"
And nothing is working now
So when i try to flash system again, windows says "fastboot.exe stopped working"
I am devastated. How can this happen? and what can I do? Please help me

So you were on cos12.1 and you tried to flash stock images using fastboot? Explain a bit what happened so that i can guide you more accurately..
Anyhow you can always go here http://forum.xda-developers.com/zuk-z1/development/how-to-flash-zuk-z1-zui-version-t3265741
And use qfil tool to flash to stock .. read a few posts below to figure out how you should do this and u will end up with zui 1.5 then you can convert to cm or any other rom

Hey thanks for the answer
So I was on COS 12.1 all normal, no root, no unlocked bootloader.
And I wanted to flash COS 12.1 again. So I downloaded the official fastboot image from cyngn . com/support and unzipped it. In there was a system.img file that I tried to flash via "fastboot flash system system.img" Thats when the error occured.
Before that I unlocked the bootloader, started the device, then I flashed the recovery and afterwards the system.
I will now look into the link and see if it helps and report back. Thanks already

Need help

Hi,, I need help, don't now what to do, I run King root on my phone, xt1562, and **** up everything.... you can see in the pics.. I search, and I can find solution, so please somebody give me the solution for this problem. I tray with adb, mfasboot, rds life to refresh on lollipop without results.

Not sure if i understand your problem, but have you tried to flash twrp to be able to boot in recovery and then flash a rom

you need to unlock your device first then flash twrp recovery , and install supersu to root the device.
try this: http://forum.xda-developers.com/moto-x-play/general/untested-how-to-root-moto-x-play-t3211941

I tray that, but don't work for me, before I start with King root I alow OEM unlock on the developer settings on the phone, and now Adb don't recognize that and ask for OEM unlock, and it impossible now cos phone don't work

Flash factory firmware, it's pretty much the only thing you can do with locked bootloader. And don't use kingroot any more

Did you originally have Lollipop or MM. Here's MM firmware:
If it's european XT1562, single sim, try this one:
http://www.filefactory.com/file/1ub...MPD24.107-52_cid7_subsidy-DEFAULT_CFC.xml.zip
If it's asian, dual sim, this one:
http://www.filefactory.com/file/49g...MPD24.107-70_cid7_subsidy-DEFAULT_CFC.xml.zip
(double check it, for you own safety)
Make sure you've got moto drivers and use fastboot or mfastboot.
What messages did you get when flashing before, what did it say exactly after executing fastboot commands?

Tnx
Before, phone was originally on lollipop, and receive Ota update on MM6. 0.1.
I tried to root this phone through this bull**** Kingroot.. And it failed.. Later on when i restarted the phone it got bootlooped and is totally bricked! i get this error- Startup Failed: Your device didn't start up successfully. use the software repair assistant on computer to repair your device. Connect your device to your computer to get the software repair assistant.
AP Fastboot flashmode (secure)
Fastboot Reason: Last time flashing failed

I try with fastboot, and rds lite, computer show connection like adb devices, but when I try to flash, said failed, and rds don't show anethyng, don't recognize phone.

If you installed MM OTA you can't flash Lollipop firmware, it must be MM (generally speaking). Get into bootloader and try to flash MM with fastboot.

I can see it boots in fastboot mode, which is good, but your firmware is messed. Is your phone sim-free or carrier branded? If it's sim-free you should be able to flash the firmware I linked.

Yes it's Sim free xt1562, model SM4232AD1T1, belive me I try everything, adb, or rds, or mfasboot., don't recognize device, in device list on comp. It's listed something like Fastbot lux... Windows 7.

P9 lite l21 tottaly bricked

So this is what happened, I was on I MedroM v3, so I was there was a firmware in beta (the 7.0 update) so I've done it and now I'm stuck in a bootloop
, I flashed the Nougat recovery so it locked my bootloader
and removed TWRP so I can't even go to flash the old rom
again. I also can't get the product id now cause I don't have an OS installed, there's no way to pull it without it an OS. I have tried every existing method possible and nothing (including the sd
card method with update.app and bla bla bla)
So I can't flash files through fastboot It says " Command not allowed"
Can somebody please help me, I have experience with flashing and everything but I in my entire life have not seen that a phone company so big doesn't have a ******** flashtool
or some other way of recovering hard bricked devices instead of buying a new motherboard or something..
If somebody could help me I would be so grateful! Please excuse my language I'm very mad and frustrated, I need my phone for work and now I'm offline..
- Fastboot is available but the bootloader is locked
- No TWRP
- No OS Installed

Download a firmware you want, extract the update.app and put it in sd card folder. From the phone completely shutdown, press vol +, vol - and power at the same time hold it until the updater with percentage progress moving appears.. you should be fine after that.. ? i believe. Maybe try it. That's what i did on my case

No, It says "Software Install failed! Incompatability with current software version"
When I go to eRecovery t says that it cant connect to WIFI.
As I said i tried every known method and I can't get it to work. Spent my whole day trying to fix it, I'm out of ideas

I had the same problem, but with the L31.
First try to use https://www.xda-developers.com/how-to-install-twrp/
Then with the file i send you attached (MAF32)
- Fastboot flash boot boot.img
- Fastboot flash system system.img
- Fastboot flash cust cust.img
- and finally TWRP
After that i puted the first exctrated uppdate.pp in my memory card and with the "3 buttons" process i flashed it. Then i repeated the same process with the second one (http://forum.xda-developers.com/hua...droid-nougat-dev-build-huawei-t3488360/page33). After this finished, again with the 3 buttons i made a factory reset.
5 minutes later, it was working.

i don't understand how to boot to fastboot ? and where to get these img files i am really stuck here pleaase

You don't understand, In order to unlock the bootloader i need the product ID which you get by typing some number combination in the dialer. I cant get to the dialer cause I dont have any OS installed, cause the old was dirty flashed. So thats why i cant flash TWRP etc..

hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM.

Ok, this is what I would do if I were you. I would pick a rom in the development section, eg. RR. Then I would extract it and get the system image and boot image and fastboot flash them. To extract the rom, use SuperR's Kitchen.
Hope this helps.

Need help P10+ bricked

Hi,
i was on VKY-L29C636 with Oreo B360. TWRP_3.2.1-0_OREO installed and rooted. bootloader unlocked
My bad i tried to unoot via supersu app and got bricked. now i cannot go to recovery.
Normal boot shows
Error!
Func NO : 10 (boot image)
Error No : 2 (load failed)
if i tried to go to recovery via vol Up + power then got
Func No : 11 ( recovery image)
Error No: 2 ( load failed)
i think i should have installed original boot.img to unroot.
installed twrp again from fastboot mode without luck.
can it be solved by installing boot.img and system.img??? but i cannot extract boot.img, system.img from update.app ( B360 firmware) via huawei rom extractor.
Thanking you...

[X01BD] Can't install TWRP after unlocking with Official UnlockTool

Hi guys,
I am using Zenfone Max Pro M2. I wanted to install a custom rom and I tried to unlock bootloader but I unlocked it through official unlocktool. Now I can't flash anything or send any command through fastboot, whenever I do then it restarts the device.
When I try to keep the fastboot command running and then connect phone - it throws errors like "Fail - Too many links", "Fail - Write to device fail (No such file or directory)" or "Fail- Unknown command".
I tried unlocking bootloader with the unofficial way provided in https://forum.xda-developers.com/max-pro-m2/how-to/unlook-bootloader-root-asus-zenfone-max-t3885457
but it isn't working either, any fastboot command is rebooting the device although bootloader is unlocked.
How do I fix this?
EDIT: Things I have tried:
- Changing USB Cable and Port
- Reinstalling ADB and device driver
- Reunlocking bootloader from UnlockTool (don't know why I did that again)
- Unofficial way to unlock bootloader
None of it helped.
Thanks

Did ur unlocking bootloader succeed?

Did you try relocking the bootloader ?
1) Try relocking the bootloader using the methods described here :
https://forum.xda-developers.com/max-pro-m2/how-to/unroot-relock-bootloader-max-pro-m2-t3885870
See if it successfully relocks...
If it does, then next time unlock using the unofficial method only...
2) If not then maybe try contacting ASUS... Tweet them on Twitter... Companies usually respond very fast on Twitter, since their reputations are at stake...
3) All else fails then try rooting it using something like Kingroot... Once rooted, flash TWRP Recovery using Flashify... then flash any custom ROM u want...
I hope your problem gets solved... Next time be a little more cautious when taking such a risky step... See what are all the options you have before jumping into something...

Tried everything except 2, none worked. I'll drop them a query over twitter like you say, let's see what their reply is.
I am on stock recovery, non working bootloader but unlocked, and stock rom unrooted.
I think Pie update may give some insight on fixing this.

I unlocked using official bootloader apk provided by asus. Now I have encrypted phone which isn't decrypting and can't flash twrp.

Hey you said phone is encrypted ? Maybe this might work :
1) Download and install the latest Magisk Manager apk
2) Extract boot.img from stock firmware
3) Put boot.img in your internal storage and open magisk app.
4) Click on install and select patch boot Image.
5) Select stock boot.img file placed in phone memory.
6) Magisk will automatically patch the stock Image and this patched image can be installed using fastboot using this command:
fastboot flash boot patched_boot.img
This will root your phone. After that you can install Flashify to flash TWRP or PBRP
Note:
- This method is highly experimental... There are 50% chances of bootloop. I would not have recommended this method, but situation seems to demand it.
- Your data will most probably be formatted, so keep a backup.
- If it falls in a bootloop, then you need to flash original stock firmware to restore your phone.
Credits: @#ArtFuL
Who came up with this method, but removed it from the main guide, because of being experimental... (I guess)

After going through the errors, I strongly believe that the problem is with your drivers. If reinstalling doesn't works, try a different pc. If your pc detects your device on MTP or your are able to perform adb operations without any hassle, it's not the problem with your phone.
You can decrypt the device only after flashing custom recovery.

3) Put boot.img in your internal storage and open magisk app.
4) Click on install and select patch boot Image.
5) Select stock boot.img file placed in phone memory.
6) Magisk will automatically patch the stock Image and this patched image can be installed using fastboot using this command:
fastboot flash boot patched_boot.img
This will root your phone. After that you can install Flashify to flash TWRP or PBRP
Note:
- This method is highly experimental... There are 50% chances of bootloop. I would not have recommended this method, but situation seems to demand it.
- Your data will most probably be formatted, so keep a backup.
- If it falls in a bootloop, then you need to flash original stock firmware to restore your phone.

Who came up with this method, but removed it from the main guide, because of being experimental... (I guess)

Yes this method is highly experimental. Also in this situation, he cannot use any fastboot commands. So this method won't work

After going through the errors, I strongly believe that the problem is with your drivers. If reinstalling doesn't works, try a different pc. If your pc detects your device on MTP or your are able to perform adb operations without any hassle, it's not the problem with your phone.
You can decrypt the device only after flashing custom recovery.

This method didn't work, as fastboot isn't accepting any command. I tried giving command before connecting phone and then connecting, it gives me error of "File size is more than max allowed".

So is it done?

I've the same problem too. Let me know if you've configure it out. Thanks.

Okay @Mr147, I've fix this. I checked Windows Update and there was a pending ASUS driver update. I downloaded it and now I can use the fastboot commands.

Anyone that can fix this problem? I also experience this.

Hi guys,
I am using Zenfone Max Pro M2. I wanted to install a custom rom and I tried to unlock bootloader but I unlocked it through official unlocktool. Now I can't flash anything or send any command through fastboot, whenever I do then it restarts the device.
When I try to keep the fastboot command running and then connect phone - it throws errors like "Fail - Too many links", "Fail - Write to device fail (No such file or directory)" or "Fail- Unknown command".
I tried unlocking bootloader with the unofficial way provided in https://forum.xda-developers.com/max-pro-m2/how-to/unlook-bootloader-root-asus-zenfone-max-t3885457
but it isn't working either, any fastboot command is rebooting the device although bootloader is unlocked.
How do I fix this?
EDIT: Things I have tried:
- Changing USB Cable and Port
- Reinstalling ADB and device driver
- Reunlocking bootloader from UnlockTool (don't know why I did that again)
- Unofficial way to unlock bootloader
None of it helped.
Thanks
