Hi Naveen, I own a Vivo Nex and I want to try the unlock method using the BL unlocker method. Unfortunately, I am unable to locate the firehose file in the stock firmware. The firmware version I downloaded is PD1805F_EX_A_1.8.5_vivo_qcom and I cannot find the firehose file inside this file. I opened it with Winrar and don't see that mbn file while there are other mbn files. Any idea how I can proceed now? If you want, I can show you a screenshot of the mbn files inside the firmware file.

The commands work when you run the commands from the adb folder only. From your adb folder press shift+right click. From the menu you will get an option "open command prompt here".

Yes you can. If you select a downgraded version from official vivo site and update system from that zip file then it should do.
[Upgrading, Modifying and Unlocking] ahhl:
how to access internal sd, cause the download file manager do not have option to access external sd.
[Upgrading, Modifying and Unlocking] BangRegar:
It's been quite a while and no indication that bootloader of Vivo phones will be unlockable in foreseeable future. More the reason to avoid these phones.

One thing I notice, the error message thrown was remote: unclock failed. Perhaps, although unlikely, the unlock command in new firmware update is now really "unclock" instead of unlock, e.g. fastboot bbk unclock_vivo ... like Vivo is trolling us the customers.
[Upgrading, Modifying and Unlocking] ahhl:
my v9 got into bootloop after an update last 2 weeks. not event my fault. its auto firmware update...

i already getting redmi note 7. redmi allows you to unlock bootloader and root. the said your responsibility. and of course. its our phone. so go buy redmi and throw and dont buy vivo no matter how tempt it is.

Still can't be unlocked?

Hello,

I'm currently using my Vivo V5 (1601)(Funtouch OS 3, Android 6). I've tried sending developer options, OEM unlock, going into fastboot, using both versions of the fastboot on Linux. Nothing works. Fastboot is able to recognize my phone but when I tried unlocking it, it says something along the lines of (REMOTE: Unlock failed).

Why did that happen? Should I be using a specific firmware version? Was this phone destined to be locked? I don't understand why the method in the first post wasn't working on my phone. :confused:

[LeEco Le Max 2 Questions & Answers] ThE_MarD:
Heyyo, TWRP version 3.1.1-0 is good same with earlier versions.

The buggy 3.1.1-1 was taken down so you're safe. :)

Ps. If you experience fingerprint reader issues when your device is asleep please flash an updated version of the modem firmware. I know it sounds odd but it does affect fingerprint reader performance when the device is asleep.

Chinese 26s 05.09 from here works good

https://yadi.sk/d/woKdrlRrv8yhr/Китай

But others have preferred developer 466D from here

https://yadi.sk/d/woKdrlRrv8yhr/Для разработчиков

Modem firmware is separate from the ROM so you can flash them freely without risk of wiping out your ROM

Try each for a few days and see which one works best for you

https://xdaforums.com/le-max-2/how-to/protocol-backup-stock-rom-flash-stock-t3517151

Besides just TWRP you can also flash MultiROM which is a great way to try out different ROMs without deleting your primary ROM

To flash this on S-On, you must have your device Relocked (on S-Off you don't need to relock) and then in fastboot mode:

fastboot oem rebootRUU

fastboot flash zip rom.zip

fastboot flash zip rom.zip

fastboot reboot

[Xiaomi Mi Max Themes, Apps, and Mods] King_pig:
I have been searching player that output Hi-Res since upgrading to MIUI Nougat 8.5.1.0 . Fortunately, I have found Neutron Music Player V 1.97.0 can output Snapdragon PCM 24bit perfectly :D:D . How about you guys? Do you have some recommendation for other music player that can also output Hi-Res on MIUI nougat?

[IMG="24bit/192khz output"]https://image.ibb.co/cjuciw/Screenshot_2017_10_10_23_25_37_312_com_neutroncode_mpeval.png[/IMG]

It can output 32 bit float & it still sounds like a **** compared to foobar2000.
[Xiaomi Mi Max Themes, Apps, and Mods] King_pig:
Don't enable 32 bit float. It will disable the Hi-Res driver. Only enable generic driver
[Xiaomi Mi Max Themes, Apps, and Mods] Zola III:
I am back to Neutron because I need 30 band graphics EQ with my can's.

You know, you should at least learn how to use it properly.

So 32 bit, 96KHz with Hi quality PCM as on screanshots.
[Xiaomi Mi Max Themes, Apps, and Mods] King_pig:
I set all my settings according to yours and my audio turned into crap. There is a lot of hissing. It can't bypass Audio Output limitation of Qualcomm 24bit PCM.
[Xiaomi Mi Max Themes, Apps, and Mods] Zola III:
Well for me it works, not that their is much difference between 24/32 bit sampling you certainly don't need more than 96KHz... The EQ on pict is for Superlux HD-668B. If you have solid can's find manufacturers frequency response graph and make EQ (negative of frequency response graph) for them.
[Samsung Galaxy Note 8 Accessories] daneshpastry:
I'm curious about the technology inside the LED Cover - what powers it? What's behind the display tech? How does the phone send it information?

Does anyone have any insight? I figured NFC explained most of it, but I was surprised to see that it functions fully with NFC being on.
[Samsung Galaxy Note 8 Accessories] pete4k:
The case gets power from the phone in similar way as wireless charging, or s-pen and those LEDs don't need much. I think it uses NFC for communication and I suspect there are some magnetic sensors that trip and let the phone know the cover is there, so NFC switch off maybe just mean it won't communicate with anything else, but cover.
[Samsung Galaxy Note 8 Accessories] daneshpastry:
So I guess some sort of conductive power method? I didn't even think of how the s-pen works - it's more than likely the same method.
[Samsung Galaxy Note 8 Accessories] cue7578:
Magnets

For clear view LED cover you will notice a round thing on the cover. It is a magnet. On the back cover also sme magnet.

LED works by magnetic induction.
[Samsung Galaxy Note 8 Accessories] jontr:
Actually NFC works with the cover on, but only when the cover is open - ie. phone is unlocked. I have no problems with pairing my NFC headphones with the cover on.
[Samsung Galaxy Note 8 Accessories] sohell:
Does this mean the wireless charging in the note 8 goes two ways?

Not only can it be used to receive a charge, but it can provide a charge, too?

Are there any other mobiles that can do thee same? Or is it a common feature?
[Samsung Galaxy Note 8 Accessories] rayraynz:
Its using NFC which has a small wireless charging component to it -

The NFC / paywave function on your credit card recieves a small amount of power which powers the chip and they can communicate at 13mhz.

The power supply can be up to 2.3 volts at 6 milliamps. Thats enough to power a few tiny LED bulbs.

As with all wireless power, it is incredibly inefficient and so i see it as just a battery drain. Probably would have been better to use a semi opaque window in the case which just shows the phone screen and positioned a clock to show through, building on the Always-On Display feature.
