[Q] I'm F*cked. Can't get intro Fastboot

So... I've flashed my baseband using the baseband software provided by this thread : http://forum.xda-developers.com/showthread.php?t=1308849
And now I am stuck at the SonyEricsson loading...
I can't get intro fastboot "mode"
And it's safe to say that I am pretty much f*cked, the working help will get a surprise.
A steam key for Borderlands.
So here is what you need to know : I am from Sweden an my provider is Telenor.
The android version before I flashed the baseband was 2.3.3. Don't know the version of the baseband. My Windows won't allow the MTP driver to be installed, don't know why. And I'm booted with the requirement of driver-signatures disabled.
Please help me!

How do you mean?
EDIT : I managed to reset to the original version.

I think that you are triying to install a custom firm without unlocking the BootLoader
Is your BL unlock?
PS: I did that error with other rom

Help with LG G4 Model Number

Hi,
I am confused regarding my LG G4 model number.
Because Under About Phone -> Hardware Info it shows LG-H815.
But when I connect it to pc & using adb devices, adb lists it as LGLS991e484402e.
Also LS991 0423 is printed on back of the phone near camera & speaker.
But under the battery the sticker with IMEI displays LG-H815 !
What is the model number ?
I need to find it in order to update it.

Are you checking for compatibility with a rom? If so, H815 is the number you're looking for.

Don't worry about the LS991 number. H815 is the version of your phone, the G4 international.

How are you planning on updating? Flashing a rom from xda-developers? If you're not sure, I'd recommend something like imperium rom, which is based on stock and has much the same behavior but is rooted with more options. Just make sure to download the one for H815. Of course, you'll need to have an unlocked bootloader and custom recovery before you can do this. Do you have custom recovery already?

Is there any way to install custom recovery without Download mode (& of course without root !) ? Because there is one more problem ! I cant get into download mode. If I use Vol up+ & insert usb cable then I get "Secure boot error 1014" & if i use adb reboot-bootloader or reboot bootloader phone restarts normally. Also fastboot mode is not working. Fastboot devices either do nothing or waiting for device ! USB debugging & OEM unlock is on.

The only method we have for our phones at this point is to use Download mode.... have you done some research on that error? Google or the forum search tool?

Yes I have searched for that & some related errors. But almost all of them says that it is because of locked bootloader & to unlock the bootloader I need to enter fastboot mode (Not working as of now) also I have tried many drivers mentioned in the posts (LG universal, LG WHQL etc), LG Bridge, LG PC suit, LG flash tool, LG mobile support tool etc & Also tried the same things on Windows 7.

I don't really know much about fastboot problems, you'll have to look elsewhere for help. Sounds like that's your next step, though. Look for people who can help you get fastboot/download mode working.

Hi Vishesh,

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!

If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

thanks everyone for all the replies!
tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock
edit:
google lens translates:
X The phone has been locked by the account number 661****647 by searching the phone, Can't unlock
but it's not the nr. of my account..

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting

I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.

Question Stuck on Fastboot (orange)

Hello
When trying to install a rom on Xiaomi.eu, my smart is stuck in orange Fastboot mode (and not with the rabbit)
I will explain in detail what I did and my problem.
I have my Xiaomi 11 Lite 5G NE 256go has the bootloader unlocked (no problem on this step)
I booted *TWRP* from my PC, I wanted to install it in my smart but it wouldn't (I forgot the error it made)
Despite this, I did a Format/Data and installed the rom "*xiaomi.eu_multi_MI11LE_XM11Lite5GNE_V13.0.3.0.SKOCNXM_v13-12*" but the procedure failed and after each restart, I only have the Fastboot mode (orange) which appears and I can no longer boot *TWRP *from a PC.
After that, here are the applications I tried to get out of this situation
Using
**_Xiaomi Unlock**: Following the recommendation of a youtuber, it's useless since the bootloader is already unlocked.
**_Xiaomi MiFlash**: By selecting the rom and the flash, it's does "*error "antirollback check error*"
**_XiaoMiTool V2**: During the flash procedure, it doesn't want to install the "*Flash super*" and by starting it again or skipping it, the whole installation is canceled.
This is what I have done so far.
I'll let you know if I have any news, hoping someone can help me.

Not only do you repeat what has already been said, but you say anything.
No, you cannot use MIFLASH with a locked bootloader.

So if u have lock bootloader u need Original Miui Rom for ur phone
U must download version what ur Phone got
Global, China or Eea Europe
U can check here what version should u Flash https://xiaomicheck.com/
If u have unlocked bootloader and flash custom rom and after OEM lock u brick ur phone and u must go to service. I pay 15Dollars to repair phone when i lock China Phone with EU Rom and lock bootloader.

There are also other tools, do a search on XDA and Google.

thx. i tried it, but the problem is that i could not get into edl. the com port is showing up for 1 sec and then it reboots and get into fastboot.
sp tool doesnt accept the scatter file from my rom.
is it possible to flash twrp with locked bootloader and restore it?
or is the only way to get a remote support?
thx

It is not obvious for recent devices if the soc is not supported.
EDL mode is only for Qualcomm devices.

i get into preloader state but wihout serial port so mtk stucks. Maybe its windows 11?
i also tried the xiaomi tool v2 but its horrible, cause our phone is not in recovery list (i wrote the developer to import it)
also in sp flash tool i don't get the button to bypass security

If still under warranty, send it.
