[OnePlus X General] _mikelanda:
I'm really sorry, i think I fixed that.

How do I know if I'm on old or new bl?
[OnePlus X General] matwaking:
Well tell me what version of stock oos you flashed last before crdroid.

If you ever flashed oos 3.x then you are on new Bl else you are on old
[OnePlus X General] _mikelanda:
It was Android 5.1.1., so I guess that oos 2.x
[OnePlus X General] matwaking:
Okay then follow the guide (carefully) to update to new BL and after you are on new TWRP flash a ROM that works on new BL (recent ones).
[OnePlus X General] _mikelanda:
When I flash OPXBLUpdateOOS3.zip I get zip signature error, what should I do? I guess I should untick zip signature, but I don't want to mess up.

---------- Post added at 03:56 PM ---------- Previous post was at 03:27 PM ----------

Just flashed them both, and when I try to flash a new rom, say Lineage OS, or even crDroid, it is on the 1+ and powered by android screen I think forever, since I've been some minutes waiting and I has been like that. Any clue?
[OnePlus X General] matwaking:
Ohh for that flash a custom kernel if it stucks on 1+ logo .
[OnePlus X General] em1000diams:
Help me please

Hi, HELP

I did what you said and IT BRICKED MY PHONE

I CANT ACCESS TO THE RECOVERY, the only thing i can access is the fastboot mode! PLEASE HELP ME!!!!!!
[OnePlus X General] matwaking:
No u didn't .

Looks like you rebooted after flashing the zip but before flashing the new twrp.

If yes then download the latest twrp and use

fastboot flash recovery twrp.img
Fastboot boot twrp.img

After in a recovery flash a newer rom.
[OnePlus X General] em1000diams:
Hi, i can't access to the internal storage of my phone, and yes i flashed the recovery, but i used the one from CM. Should I still download the lastest twrp and do what you said?

Thank you
[OnePlus X General] matwaking:
See u didn't followed what I said,also u don't need any access to phone storage in fastboot,just do what I said above.
[OnePlus X General] em1000diams:
Hi, I tried what you said, but when i type the first command, it says "FAILED (remote: Device not unlocked cannot flash or erase)"

Thank you very much for helping me

EDIT: Okay, so here's the thing, when i try unlocking bootlader via fastboot oem unlock it doesn't work, because i just realised that i didn't check the unlocking oem in developpers options. I know you wrote to check it, but is there any way to unlock the bootloader eventhought oem unlocking is disabled?
[OnePlus X General] matwaking:
Not that I know, use the mega unbrick guide and flash back all the partitions,that way your OPX will restore to oos2.2 and tou can start again.
[OnePlus X General] vaibhav97:
I flashed blu_spark v41 latest twrp when i unlocked and rooted my phone running on oos3.1.3 and it bootloops when i flash any rom.

SO After flashing the BL zip file, i can flash the OFFICIAL twrp img file???? I want to switch from blu_spark to Official twrp. Or i can flash the same blu_spark img file that i used for rooting my phone? In the bluSpark forum the developer has mentioned that he supports mainly for stock rom. But i want to flash sultan rom. Pls help.
[OnePlus X General] caparrut:
Hello friends, I have put the last update, and in this do not leave the gestures of the lintena nor radio, (V or >> that we do with the screen off) there is some way to put them.

If this is not the place to pregutar, excuse me, I change it from anywhere, thanks

P.S. Or tell me, what is the latest update that has them, thanks
[OnePlus X General] tript:
Hey!

A silly question but here goes nothing.. How do I know if I have the latest BL ? :D I Don't want to start flashing something I don't need, and at the same time I don't want to flash a ROM that's not compatible with the old BL
[OnePlus X General] Aamod Joshi:
The only way to know if you are on the MM bootloader is to flash a ROM that requires the MM bootloader like LOS 14.1 or RR 5.8.2. If your device gets stuck on the OnePlus logo without the "Powered by Android" message on the bottom after flashing a ROM that requires the MM bootloader, then you know you're on the older bootloader. If it doesn't, then you're on the MM bootloader.
[OnePlus X General] tript:
Oh I see.. Well I've only done 1 flash and that's SultanROM and that's MM rom so I guess i'm on MM BL also..

If i however flash a custom rom and after figure out I'm not on the latest BL, and I get stuck at 1+ logo, is there a guide to fix this? (I'm trying to gather all resources and flash a custom rom later)
[OnePlus X General] Aamod Joshi:
If you get stuck on the OnePlus logo with having the MM bootloader, you'll need to downgrade your bootloader. To downgrade the bootloader, follow this:

https://xdaforums.com/oneplus-x/general/guide-update-bootloader-firmware-to-t3478917/post69170103

But if you're having a ROM that requires MM bootloader, and you get stuck on the OnePlus logo, then you'll have to follow this guide to update your bootloader to get your device working.
[OnePlus X General] SeS85:
Hi guys,

before running into trouble when updating to the newest bootloader I checked the requirements carefully. During this I discovered, that my bootloader is locked:

F:\Programme\ADB>fastboot oem device-info
...
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) console_enabled: 0
(bootloader) exec_console_unconsole: 0
OKAY [ 0.007s]
finished. total time: 0.007s

Right now the phone is running CM13 from September, 23rd 2016, TWRP 3.0.2-0 and Boeffla-Kernel 5.1.

Will I lose any data when unlocking the bootloader during the process?

Thx for your help,

SeS85
[OnePlus X General] Davidroid21:
Hi all

It's safe to downgrade the bootloader?

Now I'm on MM bootloader
[OnePlus X General] Aamod Joshi:
You can, you'll not face any problems if you do it correctly. So just make sure you correctly downgrade the bootloader.
[OnePlus X General] Soldier2580:
Worked like a charm! I can't believe how hard it was for me :)

For helping future solution seekers with similar confusion reach this through google I'll describe what problems I had;

I was able to flash TWRP 3.0.0.0 and all ROMS from before Nougat. Trying to install anything from android 7 and up in this working version of TWRP, gave me the ERROR: 7 and of course, refused to install.

TWRP 3.1.0.0 was installing correctly (according to my cmd at least) but

-When trying to boot recovery from cmd (with fastboot boot recovery.img), i got the message in cmd; FAILED (remote: dtb not found) with the phone not wanting to reboot, just idling in fastboot.

-When i manually but the phone in Recovery with Power + Volume Down, I just got the boot screen, with the OnePlus logo and also the "powered by android" text appeared for a short second and then disappeared, leaving the screen on only the OnePlus logo, with nothing happening at all.

I tried many different things with the stock recovery, Lollipop original rom, updating my adb, all sorts of combos and sequences, but in the end, your steps fixed it in no time!

Thanks a bunch!
[OnePlus X General] Rodrows:
Hello!

I've been thinking about updating my phone since l'm still on the old BL and a 6.0 ROM, and before l follow the method in the OP i'd like to ask one question.

Does the new 3.1.0.0 TWRP work with both OOS2 and OOS3 ROMS? The poster above me says he had some problems so I have two options:

1. Follow OP's easy instructions, update BL, ROM, and then flash the latest TWRP

2. Flash TWRP 3.1.0.0 directly, then the ROM (although I'm not sure that would update the BL

Thanks in advance
[OnePlus X General] Plush suthar:
i have a question,

am going to update BL because of installing for a new 7.0 rom, because some error with

E: unknown command

E: unknown command

this two lines are showing, may be its because of old twrp and BL so my question is can i back on my old CM 13 rom by restoring data, after updating BL and twrp or i cant restore old backups on new BL and twrp??
[OnePlus X General] matwaking:
Follow the instructions mate ,flash updater zip ,new twrp and a recent rom and you'll be good to go.

You can restore you old rom and data but rom wont boot on the newer bootloader if its made for old bootloader .
[OnePlus X General] Plush suthar:
and what is the error...

E: unknown command

E: unknown command

can you explain why its showing?

hola, haber si me podéis echar una mano, gracias por adelantado, tengo problemas con el Bluetooth ,cada cinco minutos mas o menos se desconecta y se vuelve a conectar ,alguien mas le ocurre, hay alguna solución ,(lo conecto a un aparato de música) .

this BL is comfortable with oneplus x running 6.0 marshmallow?

Don't quote the entire OP please, and yes, it is
[OnePlus X General] Plush suthar:
okey , sorry for that :)
[OnePlus X General] Plush suthar:
Can I backup my old bootloader ??
[OnePlus X General] Aamod Joshi:
No. There's a section in the OP where you can find the zip file for the old Bootloader so you can revert back to it. Here it is :
[OnePlus X General] Plush suthar:
am going to install the ROM 7.0 nougat,

Before flashing the ROM am updating my bootloader by the zip which are given above on this thread.

My question is before flashing of bootloader its important to flash the OOS first? and why or I install the ROM directly?
[OnePlus X General] Aamod Joshi:
There's two ways you can update your bootloader.

1. By flashing OOS 3.x.x, which is the simplest.

2. By flashing the bootloader zip file provided.

It's upto you what you want to do. You can flash OOS 3.x.x, and it will automatically update the bootloader and you can then try Nougat ROMs. If you're going to flash the bootloader zip, then make sure you have the bootloader zip and the latest TWRP downloaded. Go to TWRP recovery, flash the bootloader zip, [BOLD]DO NOT REBOOT OR RESTART THE RECOVERY OR ANYTHING![/BOLD]. Just as the flashing id completed for the bootloader zip, flash the latest TWRP, and then reboot to recovery. If it boots, then you reboot you flash your Nougat ROM and reboot. It will work.
[OnePlus X General] eega:
Thanks a lot, This helped me to finally update to the latest TWRP!
[OnePlus X General] Plush suthar:
where can I find bootloader for marshmallow of my current rom?
[OnePlus X General] Plush suthar:
I did update bootloaper today,

First I update BL then update Twrp then power off my device then restart. Its horribly restarting and continuously start and off. I tried to go twrp but can't able to. Tried fast boot its showing well. But can't able to open twrp. I am stuck on that. Please guide me what to do next?
[OnePlus X General] Aamod Joshi:
Flash the latest TWRP recovery through fastboot, then boot into TWRP, and update your ROM, if you want that

Hi, I'm currently running Sultan's CM13.0 20160925 and TWRP 3.0.2.0. I haven't updated my Bootloader yet and I would like to know the different steps in order to install Lineage OS 14.1.

[OnePlus X General] Aamod Joshi:
Please check the LineageOS thread, this is the thread about updating bootloader, which is not the place to ask questions related to installation of a particular ROM, there's a separate thread for LOS.

Guys, I don't really get it.

Can I just use the latest (like, 3.1.1.0) official TWRP recovery with updated BL, or would I need to use links in the op post?

[OnePlus X General] caricatuza:
Hello

I followed the steps and after i reboot i can only see the OnePlus logo and nothing else happens.

Also, i cannot boot into recovery.

The only thing i can do is to boot into fastboot mode.

Any help with this?

I cannot flash anything from fastboot that actually works.

I flashed already the stock recovery and the version of TWRP that was working previously, but nothing happens.

My OnePlus X is the chinese version, the E1001

I will appreciate any help.

Thanks
[OnePlus X General] Aamod Joshi:
It's mentioned here,

To "NOT" reboot your phone once you flash the bootloader zip. I guess after flashing the bootloader zip, you rebooted your phone, which is the reason why nothing is working.

If I'm right, then you need to download the latest TWRP and any ROM of your choice which works on the new bootloader. Download and keep them in a folder. Follow these steps :

(I guess you already have the adb drivers installed, otherwise, why would you be here :p)

1. Open the folder where you have kept the above two files mentioned, press shift and right click, and you'll see an option which says, "Open command window here". Click on that, a command window will open.

2. Boot your device into fastboot mode, and connect your device to your PC / laptop.

3. Type in

fastboot devices

To see if your device is connected and working properly or not. You'll see some code, don't worry what it is, just ignore it. Make sure you see it, if not, then try connecting your device again, or use some other cable or something, just make sure you see some numbers and letters on the cmd window.

3. Now that your device is connected, type in these commands :

fastboot flash recovery <name of your TWRP recovery>.img

For example, if I have my recovery named "TWPRMM", then I'll type

fastboot flash recovery TWRPMM.img

This will flash the recovery.

4. Now boot into recovery, and then connect your device to the PC. You'll be able to access all the files in your device through the recovery. Now move your ROM zip to your phone, and install it via TWRP.

5. Boot your device.

It will boot up.

I hope this helps,

Cheers.
[OnePlus X General] caricatuza:
Hello..

Nothing worked.

I found a way extracting the boot.img file from the last OTA release from One +.

I flashed that file on the phone using fastboot.

After that i could use windows to unbrick the phone using MSMDownloadToolV2.0 following this threat

https://xdaforums.com/oneplus-x/general/guide-mega-unbrick-guide-hard-bricked-t3272108

I needed to flash boot.img before i use that guide because if not my windows couldn't recognise the device.

After flashing, it recognised it as QUALCOMM-HS USB Diagnostics.

finally.. the phone is working again.

Hope this helps someone else with the same problem

Cheers
[OnePlus X General] Plush suthar:
In command prompt showing that,

Device not unlocked cannot flash or erase

May be I didn't unlocked USB debugging, by mistake i did factory reset and forgot to unlocked .....

What to do next ?
[OnePlus X General] caracal:
Same Problem

Hello I try to solve my Collegues problem.

I followed the instructions to update bootloader but I have the impression that the firmware flash does not happen because the new TWRP does not work. It loops on the OnePLUS logo.

Thanks if you have any idea
[OnePlus X General] matwaking:
Well flash older version of twrp first then,then update BL and twrp

Grab the old twrp from official site (use 2.xx maybe) or the first build for our device.
[OnePlus X General] caracal:
Hello, Thanks for your reply, I reinstall with Fastboot mode the old Twrp and it good.

After i want to update BL and when i try to apply again the OPXBLUpdateOOS3.1.zip i have the same problem. No error message, no problem to install the zip and the new Twrp but when i reboot on recovery at the end of update I have the One Plus boot loop without Powered by Android.

Thanks for your time
[OnePlus X General] matwaking:
Two things can be causing that:

i) Enable OEM unlocking wasn't checked on in developer settings

ii)You forgot to flash the new twrp just after flashing the blupdate.zip (before rebooting)

Use fastboot to unlock oem or to flash new twrp and you should be good to go.
[OnePlus X General] stockPile:
I want to update bootloader on one plus one. Will this work?

Will this work for One Plus One also?
[OnePlus X General] matwaking:
First of all ,never ever ever quote the whole op.

Second this is made solely for OnePlus X,will not work on any device other than that.

Flashing it will surely hardbrick your device.
[OnePlus X General] stockPile:
Thanks .

Yeah sorry for quoting all of it. I am new to this . Thanks for the reply.I was actually flashing my OPO to lineage OS. But it failed because of "ERROR 7 oppo.verify trustzone failed".

On various forums, i found that I had to update the bootloader. But I couldn't find OPO BL update anywhere.

However, finally i found the solution. I was required to update firmware not bootloader .(Not able to post url yet).

after that problem is solved.

I am posting this here as most people would end up here looking for that problem regarding OPO. Hope its fine.

Thanks.

[OnePlus X General] Kéno40:
No if you were on PA, that means that your BL is OK.

1. Try again to wipe all data and cache from the recovery and install again.

2. You have a backup, right? Restore it

3. If still no luck, you'll have to use the mega unbrick guide

Thanks ...But still no use it's end up with bootloop only ...The third one is the option it seems ...Could you guide me in that

[OnePlus X General] Kéno40:
Your bootloader is updated by flashing OOS 3.1.4.

But you should use last TWRP version. Twrp.me
[OnePlus X General] neatworld:
Can downgrade with this method?
[OnePlus X General] Kéno40:
There is no point downgrading the bootloader.

But you can always format all and reflash OOS 2 if you want.
[OnePlus X General] neatworld:
Means, factory reset?
[OnePlus X General] Kéno40:
From the offical recovery, you don't have other option.

With the TWRP, you can manullay format what you want : System, data, internal, cache & dalvik cache partitions.
[OnePlus X General] mohawahba:
i'm just little bit confused. what is the need to upgrade my BL? i read the OP but could not get an answer for my question. Do I have to upgrade? I'm moving between OOS and custom roms normally. does the normal upgrade from LL to MM do the upgrade of BL itself? i'm just confused...

Thanks
