No point buying credits for two phones just in case it does not work.

[Android Q&A, Help & Troubleshooting] Blank tape:
Personally, I prefer the stock ROM and reinstalled it after trying a 2019 release of LineageOS 14.1. I was planning to install it again but have since had my attention diverted by other things including buying a phone released last year sold at clearance pricing. Unless you can't find a phone you can afford or plan to do ROM development yourself just for fun on a weak platform I would recommend you get a new phone and save yourself trouble and the expense of getting a boot loader unlock code. While updating the OS would give you access to updated versions of Google apps, newer apps and more recent, if not up to date security patches, Google will probably raise the bar again in a year or two and discontinue support for Android 7. As a phone, the Huawei Y550-L02 lacks VoLTE and LTE-FDD 700Mhz (B28) which is an important frequency used for coverage throughout the APAC region. Given your reference to sterling above I suspect you are not in APAC and would have been better off with the European model, the Y550-L01. There was some suggestion that VoLTE might be able to be enabled in the phone in the thread above with some reference to Magisk but you would need to research that yourself.

Unfortunately, Huawei stopped providing those something like 5 years ago.

Thanks for the reply buddy, much appreciated.

The phone itself the model has sentimental value, I bought two, one for me and one for my kid. His mum had the same model for years, she loved the phone as it only cost her $50 in Australia; so we both thought we would get one each as she has now passed on.

He wants to customise his hence the post, but I have tried and tried but cannot find a way to unlock the bootloader.

Now thanks to this forum I am hoping I can get it unlocked for him.

I'm not too grreat with tech, so it may take me some time, but I shall follow all instructions and report back if I have any success.

Again guys thnakyou for taking the time to post replies. Take care.

I'm reposting this for my reference and anyone else who wishes to unlock the Y55O bootloader. Great info.

Thanks to Senior member pndwal.

Some Good News (potentially):

I checked with DC Unlocker people whether they can continue to provide unlock codes even after official unlocking support has finished. Evidently they can.

Conversation went:

Welcome Peter W! Your request has been directed to the HELP for software usage, modem configuration department.

Call accepted by operator Valdemaras. Currently in room: Valdemaras.

Peter W:

Please let me know if your software (or HCU-client) will still unlock bootloader on Huawei devices released before 24/05/2018 (specifically Y550) after today's (23/07/2018) official end of Huawei unlocking support.

Valdemaras:

Hello, it won't be able to unlock bootloader, it will be able to read bootloader code only

Peter W:

Will this enable me to unlock bootloader?

Valdemaras:

if you know how to use the code then yes

Peter W:

So is this the same as bootloader unlock code?

Valdemaras:

yes...

Peter W:

Great. So can I assume this method will continue to work despite Huawei officially closing unlocking support?

Valdemaras:

yes, reading bootloader unlock code will still be available after they close their official website for it

Peter W:

That's good news.

Peter W:

What about unlocking bootloader on Huawei devices released after 24/05/2018 (officially unlockable if released after that date)?

Valdemaras:

we do not have specific list depending on release dates, you can check what device are supported for bootloader unlock code reading here:

Peter W:

Many thanks for assurances.

Peter W:

Any recommendations on whether to use HCU-client or DC Unlocker for bootloader unlocking?

Valdemaras:

i repeat again

we do not unlock bootloader

can use any of the tools for reading bootloader unlock code from phone

Peter W:

Thanks PW

Valdemaras:

Y550 is supported by DC Unlocker, and they quote 4 credits (4 EUR) to read bootloader unlock code. (Also, 4 credits to unlock SIM, if you wish).

Their tutorial is here:

How to read Huawei Android phone bootloader code

read huawei android phone bootloader unlock code dc-unlocker

I've unlocked both Y550 bootloader and SIM using DC Unlocker previously without problems.

It seems this method will continue to work, albiet at a small cost (SIM unlocking price was the best I could find in the past), and this is a reputable / professional service, so this may be the best or only option for new Y550 custom rom users (and other Huawei owners).

Please would anyone using DC Unlocker after today confirm that it does still work (for new Custom Rom users).

Hope this helps new users. PW

[Android Q&A, Help & Troubleshooting] pndwal:
I fiddled with experimental module and VoLTE provisioning, but was never a able to make it work on Y550.

I now use Xiaomi models, and note that early iterations of VoLTE may be fraught even when supported due lack of support for later protocols; VoLTE was working fine on both Redmi 6 and Redmi Note 8T, but I had to disable it on the R6 about a year ago when Vodafone upgraded network and calls started failing to connect altogether... No issues w/ VoLTE off... No such problem with newer RN8T. PW
[Android Q&A, Help & Troubleshooting] Blank tape:
Sorry for your loss, but I will be a pain and point out that installing another ROM will make the phone behave differently. Wouldn't that destroy some of its sentimental value? I don't know whether you've both used the phones enough to be aware of the limitations but if not please manage expectations of your son. I don't know where you are but possibly even now the phones lack of band support and VoLTE will be limiting your coverage. It will be perfectly fine for running some apps but web browsing will be slow on perhaps the majority of web sites. Some apps will be perfectly fine though. Navigation apps suffer at least on the stock ROM from the GPS regularly losing lock unless the phone remains connected to a power source. Replacing the ROM will allow you to get newer apps and newer versions of existing apps and the adoptable storage feature allows the internal storage to be extended by the capacity of the SD card but makes the SD card integral to the functioning of the phone.

FWIW, EUR 4 = approx AUD 6 unless you're getting a great deal.

Damn, I thought I got a good deal from Hardly Normal around Easter 2015. Did you get the $50 starter kit with yours too? I managed to get the starter kit applied as a lower value combo recharge to an existing plan. In hindsight, I wish I'd bought another one too. Even now I wouldn't mind another Y550 with an unlocked boot loader for the right price but it probably would just sit around here as another stalled project. My new phone has an MTK chipset and needs some hacking even to get fastboot and adb working in recovery apparently. D. Smith is a dirty word these days itself.

Regarding installing LineageOS, FW wrote a couple of excellent posts here (in Dutch, Google translate does a pretty good job.) You can use a later version of TWRP. If any OTA update has been applied, fastboot flashing of TWRP will not be effective in changing the recovery to TWRP so you need to boot TWRP instead each time you wish to use it. I'll also point out that TWRP will not back up all partitions on the phone. You can use adb to do that. I can't remember whether restoring from TWRP backups was enough to get the phone up and running on stock but installing the first OTA update from Vodafone AU (B247SP01) certainly did.

Occasionally the thought that I should return the phone to Vodafone and demand that they either enable VoLTE or replace the phone goes through my head. As Vodafone originally originally claimed that the phone supports VoLTE I believe that would be a valid claim under ACL though they probably would need to be prodded by the TIO. If I were still a customer I might have done something about it but I wouldn't like to return the phone and get something less hackable in any case.
[Android Q&A, Help & Troubleshooting] pndwal:
Personally, found LTE coverage quite acceptable in Sydney on L2 (w/ updated baseband)... VoLTE only allows LTE and simultaneous voice call; without, data drops to 3G.

Yup, Adopted Storage is ESSENTIAL on this phone... Unless you only have 2 small apps. 🤪

I bought about 8 of these... Couldn't resist the last couple at $35!... I'm pretty sure even these had the starter pack!... (This was the real D ick Smith).

and I believe D ick Smith is now a Kogan sub brand... Think they bought the name...

My first 'computer' was D ick's VZ200 (Z80) replete with data cassette deck... Needed a few blank tapes...

Haha! Vaguely remember that claim... Several of us tried since SD410 specs support... Perhaps Vodafone just read that too... PW
[Android Q&A, Help & Troubleshooting] Blank tape:
700Mhz (B28) provides both coverage and in-building penetration so it is useful to have. Vodafone only picked some up by virtue of integrating TPG's holding. Prior to that Vodafone only had 850Mhz (B5). B28 has more bandwidth available than the bands that were originally repurposed from 2G. Grey imports often lack it.

I've managed without it and the alternatives like Link2SD but the lack of storage has made it a pain to update larger apps at times. Judicious clearing of app data helps with some apps left at stock and some stock apps disabled. I was warned about the lack of storage but I didn't listen. Little did I know that Android keeps the factory versions of the apps around.

Hence my comment.

Cheers Buddy. Yep she paid $100 with starter kit. We are currently in the UK.

Yep it costs $6.75 I got the costs wrong.

I'm going to unlock both boot loaders as I like full root access to declutter any unwanted apps.

I'm struggling to buy the four credits at the moment.

I no longer have the cell number associated to my bank card and it's asking for a code sent to this number when buying the unlock credits.

So until the bank change the cell number I'm stuck.

[Android Q&A, Help & Troubleshooting] klaidone:
Try one more time ;) But after flashing a stock ROM, then stock recovery flashes, too. After that you allways can reflash CWM or TWRP recovery.

If immediately goes to TWRP recovery, on microSD is something else without dload folder. In my experiments I got a similar result. If there is something.zip file else - all goes right, but if there is another files and folder from Android installation - allways flashing goes to recovery for me.

BTW - I never can flash 239 rom file. Never. But all versions of 432 flashes on the fly w/o any errors.

It didnt work for me, the three button combo takes me to recovery (not twrp) and I have option to apply update from sd card. but i cannot see dload folder.

I always make a nandroid backup before flasing any other custom rom. (Which works perfectly)

Just put the 'dload' folder onto your root of your sd-card. Press Power + volume down + volume up together for about 5-10 seconds. This should automatically start the flashing routine, which brings you back to fully stock.

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,

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?
