1- No, close (without showing error) new apps after request and allow (allow [app name] to access photos, media and files on your device?).

2- yes
[Android Q&A, Help & Troubleshooting] pndwal:
Ok.

1) It's still not clear to me what the problem you are having with permissions is, but permissions can all be toggled on or off under indivdual apps (Apps menu) in settings, or from Configure apps (cog at top of Apps menu in settings), App permissions. Also, you could try Advanced, Fix Permissions in TWRP.

2) Just noticed you had actually replied regarding call problem (It got put within grey quote of my first reply to you due to messed up reply formatting. Take care with this!). Seems you are still finding phone slow to turn on screen when receiving calls in order to accept or reject. (?) Not sure why this would be, but phones performance can be quickly diminished if running low on memory space, and we have very limited (approx 3.64 GB) internal storage space on Y550. You should check there is a reasonable buffer of empty space (ie 300 MB or so). (I use adoptive formatted SD card (must be a fast one) and migrate user data and transfer all possible user apps to it for this reason. This keeps approx 500 MB internal free).

Let us know how you go with it. PW

I just used the phone after a few months. Great Rom, really. I use adaptive storage and it's very good. The only thing is that I tried to do a twrp backup but it goes on internal storage and after that it appears the message full memory. So I had to delete it. Any workaround?

Inviato dal mio Redmi 4X utilizzando Tapatalk
[Android Q&A, Help & Troubleshooting] pndwal:
Are you using official TWRP from twrpme, or an unofficial one? I know only official sees adoptive storage properly (eg in advanced / file manager - read post #6131), so if you're using unofficial, trying official (by [MENTION=6829336]Hacker432[/MENTION]) will likely work properly and write backup to SD. Let us know. (If it works, don't forget to transfer it off SD, as unless you back up encryption key, if system is lost and key is gone/corrupted, you won't be able to retrieve anything off SD card including backup, and with key, only if SD is in identical phone!)

[Don't forget, for good results with adoptive storage you need a fast SD card. I use 80MB/s SanDisk Ultra 64GB SDXC, but faster would be better.

Also, if Devs haven't added 'move app to SD' support for some apps (and you want to move more), you can still move them by selecting 'Force allow apps on external' in Developer Options. (Makes any app eligible to be written to external storage, regardless of manifest values).]

See post #5784 for my tips re. adoptive storage. PW.
[Android Q&A, Help & Troubleshooting] pndwal:
Just performed a backup on L02 using official TWRP 3.2.1-0 and it worked fine, saving to adoptive SD - /external-sd/media/0/TWRP (4145MB - 4 partitions). There is also option on setup page to 'select storage' - internal / SD. Seems to work ok. PW.

7.1.2 update

Thanks to [MENTION=4479868]desalesouche[/MENTION]'s instructions in this post I have been able to build LineageOS 14.1 (Android 7.1.2) containing each month's security patches: April, May and June, all thanks to the LineageOS-developers and (among others) [MENTION=4479868]desalesouche[/MENTION].

Kernel: https://github.com/HUAWEI-Y550-Y635/android_kernel_huawei_msm8916/commits/los-14.1

This is today's build, containing the June-2018 security patches, hosted on mediafire.com.

Update: download links have been removed. Please use the most recent ROM, see this link:

Unofficial LineageOS 14.1 (Android 7.1.2) ROM with Juni-2020 security patches

Bugs:

So far, a few things have caught my attention, but they're not critical for my daily usage.

- the Google calendar app can be used normally, but sometimes crashes without ever being started (at system startup, for example)

- the Wifi MAC-address sometimes switches between a Huawei-prefix 68:a0:f6 and an Airgo-prefix 00:0a:f5 on reboot

- Settings/About phone/Device model reports 'cherry' instead of Y550-L01 or L02 or L03 (thanks [MENTION=7550078]pndwal[/MENTION] for reporting)

Feel free to test and report, but I will probably be unable to fix anything :). I'm just happy with an up-to-date 7.1.2.

Latest Y550 ROM and fix for speaker feedback

Hi guys,

I just tried updating my y550-l01 to LineageOS version 14.1-20170128-UNOFFICIAL-cherry, which is what I found before locating this thread.

I am not so interested in having the latest version but there is some speaker feedback and the Phone program will not hang up.

I have looked around and there seems to be a separate modem ROM that will fix the speaker feedback, but I am not sure whether that is independent of the LineageOS version, and I also haven't found where to download it.

I also found a latest build mentioned https://xdaforums.com/showpost.php?p=76821797&postcount=6145, lineage-14.1-20180615-UNOFFICIAL-cherry.zip

If I apply this latest ROM is likely to fix the speaker feedback problem and the phone hangup as well?

Do I also have to reinstall the OpenGapps ROM as well?

Regards,

Frank
[Android Q&A, Help & Troubleshooting] fwiep:
Welcome!

The modem-zip can be found on post #2 of the Y550-thread, section "modems", 4XQWT_LP_Modem. Direct download from mega.nz.

It has to be flashed only once, when coming from a stock ROM.

For me, the newest ROM has no speaker feedback (see discussion a few weeks ago regarding fluence-setting).

The hang-up problems were fixed as soon as I flashed the aforementioned modem.zip.

Yes, I recommend to flash the newest OpenGApps. Choose ARM, then 7.1, then the variant you want (I use "pico").

Advantage of flashing the newest OpenGApps together with a (new) custom ROM is a few MB's of extra free internal memory after the flash.

Kind regards,

FWieP

Note: This phones performance can be quickly diminished if running low on memory space as we have very limited (approx 3.64 GB) internal storage space on Y550, and only about 1.62 GB is available (the rest is partitioned off for system apps and files). You should check there is a reasonable buffer of empty space (ie 300 MB or so). (I use adoptive formatted SD card (must be a fast one) and migrate user data and transfer all possible user apps to it for this reason. This keeps approx 500 MB internal free).

See my post #5784 re adoptive storage (you need a fast SD card as I mentioned there), and if game won't natively load in adoptive, enable 'Force allow apps on external' in developer options and move to External in settings / storage.

Nb: post numbers don't show if using XDA labs app, but show if opened in chrome.

These latest ROMs are the best yet, and your problems really are the physical limitations of Y550s 1GB ram and 4GB (1.6GB available) internal memory. It's a low end, low spec phone with a middle end processor, not really a game level device.

Nb. The ROM you are using is [MENTION=7866480]fwiep[/MENTION]'s first attempt to make ROM for our device (it has benefit of later security patches but may have unknown issues). Most are using [MENTION=4479868]desalesouche[/MENTION]'s lineage-14.1-20180518-UNOFFICIAL-y550.zip, posted 2018-05-19.

(im not tried adoptive storage in latest des roms)

my problem is with 1gb ram(in settings shows total:888mb, 100 mb lower than other phones with 1gb ram! wtf) ,when using stock browser and a downloader app(ADM) or when running games, with huge ram usage, ram become sufficient and it hangs 2/3 mins then the system ui restart(is this bug?)

but snapdragon 410 can handle almost all games optimised for 1gb ram

[Android Q&A, Help & Troubleshooting] pndwal:
80 MB/s should be OK, but you may have a defective card. Adoptive works beautifully with N, unlike M, and perfectly for me. As I mentioned, this phones performance will be quickly diminished if running low on memory space, and you should check there is a reasonable buffer of 300 MB or so free. (I'd be surprised if you can achieve this with even normal array of apps installed, let alone with large games.) I have many apps, and still have approx 500 MB internal free.

Please note my additional edit in post above regarding [MENTION=7866480]fwiep[/MENTION]'s ROM. You may want to swap and try [MENTION=4479868]desalesouche[/MENTION]'s to check if phone hanging and ui restart is a bug in your ROM. I have never had such issues (although I don't use stock browser or ADM much), but suspect it may actually be related to low amount of free internal memory as mentioned. Also, your RAM levels seem normal. My system reports 889MB total, 176MB free.

For your type of usage, I'd be trying to get adoptive storage going. It is designed to minimise the limitations of phones with limited internal memory like ours, and generally does the job well since android N. Worth trying another / faster card. PW.

---------- Post added at 02:56 PM ---------- Previous post was at 02:48 PM ----------

Yes. So check how much internal storage is free. 300 MB? Use adoptive if not enough free, or you will, in my experience, suffer a dramatic performance hit. Regards, PW.

Hello all,

As some of you might be too, I am anticipating the integration of this month's security updates into our Y550 custom ROM.

I found this page among the Cherry-pages at LineageOS. As soon as the next "Bump security string to..." is mentioned there, I will build another image and post it here.

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:

https://www.dc-unlocker.com/android-feature-table

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:

welcome

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:

https://www.dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code

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
