This is another application which I have on good authority works to unlock the bootloader.

The license seems a bit pricey though, trying to find a one off cost or a credit trial version.

While I now understand that we really shouldn't be discussing ANY paid service on XDA , I did post re several B/L unlock services here in the past... The one I mentioned was the most reasonable then by a long shot, and I was not unimpressed by the personal help given to boot. ... PW

I can't help you with this specific problem, but I know you'll get decent advice from the DC-Unlocker people via their chat; the big Message button on the bottom right of their site starts a conversation. If it's outside their business hours (GMT+2), you'll get an e-mail and the conversation will continue that way.

Last week, thanks to the recent revival of this XDA thread, I tried to resurrect my old Y550-L01 once again. About two years ago, I somehow bricked it hard. Now, this made me contact the DC-Unlocker people and use their DC-Phoenix software. It all looked very promising (downloading the stock firmware, bootloader, etc. from their servers, detecting the device both in some kind of fastboot mode when an SD-card was inserted, and Qualcomm HS-USB QDLoader 9008 mode when not).

The flashing failed repeatedly, so I chatted with them. Followed their advice, and chatted again. Followed their advice and mailed some logs... All to no avail. Their conclusion was (as is mine, and was ours in this thread, two years ago): the motherboard would have to be replaced to revive it. For me, that's not an option, so I handed it over to our city's recycling facility. I put a printed note inside pointing to this thread, so that anyone who tries his/her luck with the device, won't have to start from scratch.

TL;DR: seek out the assistance of the DC-Unlocker people; I spoke to and mailed with Waldmeras and he was very knowledgeable and friendly.

Good luck and kind regards,
FWieP

Nice post buddy. I just cannot seem to connect to DC Unlocker servers; I keep getting this message bottom below.
I have no antivirus software running, disabled the firewall, no VPN, no proxy server.

I have no Ethernet connection options available to me I can use; so I can only either hotspot off of Android, or USB connect via Apple or Android. I have tried the SIM in a Telstra unlocked USB dongle and a Telstra unlocked wireless modem and connected my PC by wireless connection to the modem. I have tried it on two different PC's, I have run DC Unlocker as Administer, still no luck. I am at the end of my tether to be fair. My last port of call is using the wireless service in my local Pub or/and swimming baths or library. Otherwise I am stuck.

The funny thing is, I can only nail it down to one of two things, either you have to use a Ethernet connection (fixed IP), because my IP address seems to be dynamic. As whenever I go to Google, and ask, where is my IP location, it changes often and is no where near where I am in the UK, it's like 200 miles away. I am wondering whether this is having any effect? I am stumped.

Tried this also, still cannot connect, any thoughts friends?

Control Panel\Network and Internet\Network Connections\Local Area connection 14 Network 247
Right click on your device that you want to unlock connection > Properties >
Internet protocol (TCP/IPv4) > Properties > Advanced > IP settings > Uncheck "Automatic metric".
Set Interface metric as "5". OK > OK > Close

I had several similar experiences in the past...

Also worth noting that 410 series was highly susceptible to overheating and subsequent emmc (results in HS-USB QDLoader 9008), charging port, USB connectivity and other issues... Several sagas in this thread, and I had USB failure on two devices... PW

Managed to connect to the servers at last, albeit via the local pub Wi-Fi. Received the boot loader unlock code. Worked a teat and unlocked the boot loader no problems.

I have installed (TWRP 3.5.2_9-0) via fast boot. Does that seem all fine so far? A little problem when booting out of TWRP, seems to only switch off then difficult to switch back on.

Next I want to install SU Super user, any preferences guys for this modal, or does in not matter.

Was thinking of this one. SR5-SuperSU-v2.82-SR5-20171001224502

Now I am stumped installed SR5-SuperSU-v2.82-SR5-20171001224502, and Root explorer is saying the phone is not rooted?

I think I need to Flash Magisk to obtain root permissions; yet because I am currently running Android 4.4.4 I am struggling to find a compatible version which will install. Am I on the right track?

Using Root explorer, I cannot seem to gain entry to the Root/Data directory, its stating the phone is not rooted. Superuser SU is not granting priveledges to Root Explorer. I had this problem on another phone, I installed Magisk, and it granted priveledges to Root Explorer. But as I am on Andoid 4.4.4, I'm struggling to find a version of Magisk which installs and works in the correct manner

I believe magisk won't do this anymore, and Chainfire sold SuperSU to a Chinese company years ago! (Good on him!)... Magisk is now the defacto root solution, and it's open source to boot!...

Do yourself a favour, cleanup SuperSU, ditch 4.4.4 and install this 7.1 c/o @fwiep w/ adopted storage working out of the box (just be sure to update baseband as I mentioned):
https://forum.xda-developers.com/t/everything-huawei-y550-root-cwm-twrp.2923318/post-85363935

Then install Magisk!... PW

Hey bud, how do I clean up Super SU. I have no root access and because I flashed it, well its a system file. Not sure to to remove it.

 

[pndwal]

Just reflash latest stock fastboot ROM then I guess. Best to do this before a custom ROM install in any case ... Cleanup options were in SuperSU app IIRC... PW

For L02, L03 official twrp gives these errors (seems original Dev was only concerned with L01). For these variants, use last Unofficial TWRP 3.1.1.0, Dec. 16 2017 by desalesouche for flashing.

Yep I've the same problem, error message when trying to flash lineage-14.1-20210803-UNOFFICIAL-y550.zip.

Clean install,any tips or links where I can find the Unofficial TWRP 3.1.1.0, Dec. 16 2017 by desalesouche.

I found a 3.1.1.1.0 version but the image was too big to install.

My phone will only boot in to fastboot and rescue mode. I formated the drive installed a version of 3.1.1.1.0 rebooted and now I have a phone with no operating system and can't Boot in to recovery mode. Any thoughts.

Managed to solve the above issue. Back to stock ROM.
I'm L02 I can't seem to find a TWRP and custom ROM which will allow an install. I do a clean install. Tried three custom ROM now all failed to install

I've found unofficial TWRP 3.1.1.0, Dec. 16 2017 by desalesouche. Still not allowing install. I've tried two of his ROM with it and it fails.

Screengrab. I'm stumped.

Did you confirm you have 3.1.1?... How are you installing the twrp?... Are you first extracting the .img file, then flashing that to recovery partition as .img? PW
