I'm talking about my Y550
[Android Q&A, Help & Troubleshooting] lin_ux:
Welcome to the Y550 thread... :)

No it is not possible with the Y550 model.

None of the cheaper model Huawei phones have this ability.

The feature you are taking about is called OTG (On The Go) and it is usually only found on expensive phones, the manufacturer needs to include this in the design of the hardware which costs them slightly more, so it doesn't get added to budget models like our Y550.

GPS issue

Hello there,

I got an issue with gps - at first - all of navigations or sport trackers I've used, were loosing gps fix and it didn't catch again. I made factory reset and it almost helped.

But about 2-3 times for hour, it still looses fix, but catches again in few seconds - is that normal?

And one more thing - gpx possition in any map app is very snatchy - in car it refreshes after thirty forty meters... I can still use it but it's annoying.

I've read abut it in czech androidforum, more customers have these problems. Huawei support said they notify Huawei center and update will by made, but - when?

What do you mean, where's the problem? THX

I use 220 with aviate launcher and that's perfect
[Android Q&A, Help & Troubleshooting] lin_ux:
You were awake late taking screen shots at 2:24AM, I'm usually nocturnal as well (but in a different time zone to you) so I can fully understand this... :D

For the launcher you are using 220 looks great (thanks for the screen shots!), and as I'd mentioned in my post, it also looks OK when using the stock Huawei EMUI launcher, anything lower than that looks real odd...

However with Nova launcher set to show 6 rows of icons on the desktop I find 220 is still way too "chunky" for my tastes ;)

I've balanced the DPI on mine to match how the screen looks on my G526 (it has a higher native resolution) which has always looked perfectly proportioned for a 4.5" screen...

I use a lot of widgets to show text information, such as full month calendar views, where each days event is shown in tiny text, not just coloured blobs, and any DPI which I set higher than 215 does not manage to scale it cleanly.

We are very lucky that we can tweak it to suit our individual tastes, I'm real happy with the way mine looks, and I'd imagine you are with yours too.

Luckily it's so easy to try out different DPI settings till you discover one that suits your preferred system layout and eye sight strength...

This really is my favourite system tweak on the phone, I'd give up all the others rather than losing this one! :D

I do remember that the Wifi-MAC toggling occurred in the past, i.e. in the time of [MENTION=4479868]desalesouche[/MENTION] 's 7.1 ROMs.

The Google Calendar issue is new to me. I can not reproduce it to help debugging - let alone fix it. Perhaps it's related to the OpenGApps I frequently flash.

Kind regards, FWieP
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks. Can I assume you are using recent / up to date OpenGApps? PW
[Android Q&A, Help & Troubleshooting] fwiep:
Yes, always the most recent: ARM, 7.1, pico => 2018-07-24 as of this writing.

FWieP
[Android Q&A, Help & Troubleshooting] pndwal:
Good. I find nano fine. PW

General Tip (for all):

Unless you integrate them, updated system apps will be in internal (user), and original (deactivated) will be retained in system, so using old GApps wastes space in internal as many updates will be installed when first updating (ie. more deactivated/ redundant apps retained also), and more will be installed over time.

If not integrating regularly, installing latest GApps periodically will therefore minimise wasted internal space, which is important on our device with limited internal storage.
[Android Q&A, Help & Troubleshooting] fwiep:
Yes, I would surely like to fix these things. But to be honest: I don't have a clue how to start.

Personally, I would like to have "Y550-L01", "-02" and "-03" back again as the device's name when connecting via USB or Bluetooth (now it shows "cherry" for all devices).

Is this controlled via .mk-files? How does one work with variables in there?

As 7-of-9 would say: please elaborate.

Thanks,

Thanks

Just to say thanks to everyone who's contributed to this thread. After much deliberation I took the plunge and installed the latest lineage OS on my stock Y550 L01. The steps I took where to:

install TWRP (my y550 was already rooted)

install lineage ROM

install modem

install pico gapps

I rebooted my Y550 and some minutes later it started with no problems that I've found yet. Adoptive storage, bluetooth, phone calls, WiFi, camera, charging all work as expected. Thanks!

Actually there was one slight problem in that I couldn't get root to work. So I had to additionally flash SU (arm) 14.1 from lineage/extras which worked like a charm.

So thanks again and keep up this great work! :good:
[Android Q&A, Help & Troubleshooting] pndwal:
We previously had charging problems due to bad boot.img. [MENTION=4479868]desalesouche[/MENTION] fixed boot image and changing was cured. Guess you could go back and try flashing the experimental boot.img that fixed it then. Link on page 576 still works (- batt4-boot.img.) PW

---------- Post added at 05:18 PM ---------- Previous post was at 05:06 PM ----------

Good stuff!

Re root, I use Magisk, which also flashes without problems, as there are many useful modules (incl. busybox, sound enhancements, and many other mods worth considering / experimenting with) accessible thru Magisk manager, and these can be toggled on or off easily. You may now have to clean up SU, or extract and reflash original boot.img if you want to try Magisk and encounter errors flashing.

Regards, n welcome to custom Y550. PW
[Android Q&A, Help & Troubleshooting] blairfancy:
Tested batt4-boot.img but no improvement .
[Android Q&A, Help & Troubleshooting] GotoDengo:
Thanks for the tip about Magisk, I'll have a look but I'm not sure I need all the extra functionality. BTW did you know that there's a "remove SU" zip on lineage/extras which would seem to cleanly unroot your phone for you?

Finally I'm loving adoptable storage, no more having to micro manage my storage when installing/updating apps. Phew!
[Android Q&A, Help & Troubleshooting] pndwal:
Yes, you should flash that, or run cleanup from within SuperSU app before migrating to Magisk, but sometimes it doesn't restore boot.img to unmodified100%, and easiest way to overcome errors flashing Magisk is to extract original boot.img from ROM package and flash it first. Also, if you're going to play with Magisk modules you're unsure of, you can first flash Magisk Manager for Recovery Mode (Allows you to disable mods from recovery in the event one prevents phone from booting). I've never needed this however.

Native adoptive storage does now work beautifully in N. Nb. In developer options you can 'Force allow apps on external' (overrides manifest values that prevent moving apps to SD that would otherwise be eligible) if you find there are too many that won't move because of lack of provisioning by developer. However, sometimes you will want to move apps back to internal - eg ES File Explorer won't toggle on Root Explorer (in Tools) unless installed in internal.

Glad it's all working well for you. PW

Here is Rom information. Earpiece sound is very low

Inviato dal mio G8441 utilizzando Tapatalk
[Android Q&A, Help & Troubleshooting] pndwal:
OK, so you have 2017 ROM.

As I mentioned, 'Previous audio problems have been fixed on ROMs since Jan / Feb 2018, ie no more echo for other party, speaker loud, volume adjustment working etc, and some complained in call earpiece volume is too loud! See discussion from about page 600 onward in this thread.'

So I think you simply need latest ROM by [MENTION=4479868]desalesouche[/MENTION] or [MENTION=7866480]fwiep[/MENTION], to take advantage of [MENTION=4479868]desalesouche[/MENTION]'s methodical work updating the bad commits from original Cherry port which caused problems like yours. Using any ROM since Jan / Feb 2018 should fix audio, and you can dirty flash, leaving your settings and user data intact. Regards, PW
[Android Q&A, Help & Troubleshooting] GotoDengo:
Great tip @PW, thanks! I was scratching my head over some apps that I couldn't install/move to the SD card.

One problem I've found is that "Encrypt Device" doesn't work. The phone simply reboots and does nothing? Not a major problem for me, just irritating.
[Android Q&A, Help & Troubleshooting] greenlabel:
Thank you very much for your help. Can I dirty flash it or it's better to do a clean install??? Thanks

Inviato dal mio G8441 utilizzando Tapatalk
[Android Q&A, Help & Troubleshooting] pndwal:
It's up to you. I regularly flash updated ROMs dirty to avoid setting up phone each time, and generally this simply fixes bugs / updates security etc, but leaves setup as it was. This would simply be an update of unofficial cherry for you so dirty should be fine. I'd only clean flash if I thought it might fix some specific problem, or if swapping to a different ROM altogether, eg from unofficial cherry to RR.

You will probably need to reflash SU for root as unrooted boot.img will be restored when flashing ROM.

Tip: It's a good idea to install latest GApps package periodically also (not just update from playstore), to minimise wasted internal space. Explanation in post #6186.

Hope it helps, PW.
[Android Q&A, Help & Troubleshooting] pndwal:
Glad that helped.

Regarding Encrypt Device, guess this is 'Encrypt phone' in settings /security.

Did you unroot first? 'Encrypt phone' requires unrooted boot.img to work (LineagOS people should really add a note regarding this on 'Encrypt phone' info page), so simply unrooting from your SU manager, flashing "remove SU" zip you found at lineage/extras, or extracting unrooted boot.img from ROM package and flashing this first should allow encryption to work, then re-root afterwards.

Hope it helps, and if you succeed with it, please let me know if there is any performance hit when using encryption on Y550. PW.

Thanks guys, I dirty flashed the last delal version, it seems OK! Adoptive storage and modem are still OK and earpiece seems to work properly.

The only strange thing is that I've been not able to find Rom in the SD card trough twrp (I think it depends by adoptive storage, folders I see with the file manager when phone is switched on are different from the ones I see when I try to flash something through twrp), so I used adb sideload.

[Android Q&A, Help & Troubleshooting] pndwal:
Remember my reply to you re. TWRP backup with adaptive storage in June? :):

You said: The only thing is that I tried to do a twrp backup but it goes on internal storage...

I said: 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...

Sounds like you're likely still using unofficial TWRP and having the the same problem. Unofficial TWRPs from this thread simply can't see SD formatted as adoptive, so you won't find ROM to flash if saved to adoptive SD. Swapping to official TWRP from twrpme solves this. However official TWRP fails (with error 7) to flash any recent ROMs on LO2 and probably LO3. See my workaround in additional info. below unless you have L01.

Latest official is 3.2.2-0, July 2 2018 (https://dl.twrp.me/y550/) by [MENTION=6829336]Hacker432[/MENTION].

Latest unofficial is 3.1.1.0, Dec. 16 2017 (https://xdaforums.com/showpost.php?p=74856798&postcount=5850) by [MENTION=4479868]desalesouche[/MENTION].

Nb. Neither of these latest recoveries are yet listed at https://xdaforums.com/android/development/huawei-y550-development-t3425524 post#2 by [MENTION=6726815]Saint_13[/MENTION], but the link to official TWRP page is there.

Additional info re. TWRP differences and usage:

Consistently, official twrp is the only one that can display Adoptive Storage, (I guess it correctly uses encryption key at data/misc/vold), however it fails (with error 7) to flash any recent ROMs on LO2 (and I suspect on LO3 as in the past).

For this reason I still need to have unofficial twrp loaded to install ROM, and as unofficial twrp (incl. [MENTION=4479868]desalesouche[/MENTION]'s) cannot see my SD formatted as Adoptive, must swap and load installation files onto another SD formatted as portable, then swap to official twrp if I want to access my phone data in recovery.

(As you can imagine, things would be a lot simpler for LO2, LO3 users if either official twrp could be made to load ROMs on LO2, LO3, or unofficial twrp could be made to recognise Adoptive Storage.) PW.

[Android Q&A, Help & Troubleshooting] greenlabel:
I really don't know how to say thank you for the time you spend to help people here! Now I remember what you told me. At that time I did not install official twrp because, basically, there was no way to start recovery by phone, it only starts via adb, so I was afraid to make a mess because phone, finally,goes really good. I've L01, so, if I understood good, there's no contraindications in using official twrp. I'll try to flash it (via sideload I guess, but maybe I can start directly official twrp via adb and then I'll see the internal storage of the phone). Just a suggest please. To flash recovery via twrp I must use the usual command 'install zip ' o something else? Really I don't remember

Had to look up the medical parlance (Do I have the pleasure of addressing Dr Greenlabel?) Yes, your understanding is good, there are no contraindications I'm aware of prescribing official TWRP for L01 (neither relative nor absolute). - Don't worry, the patient will not die!:)

More seriously, do you have trouble starting TWRP by holding vol. up (hold this first) and then power (keep holding both) till phone vibrates? Whatever recovery you have should start this way, [if you still only have android recovery booting with vol up and power buttons and still have to flash ROMs by booting twrp image from PC, start TWRP this way in any case,] then you should be able to swap TWRP by flashing img file - click Install and find file location (won't be visible till you click 'Install Image', NOT Install Zip), then click Reboot / Recovery. [If new recovery doesn't start this way I guess you can still boot official TWRP image from PC to see adoptive storage].

To see your files in unofficial TWRP, I suggest you copy installation files onto another SD formatted as portable, power off phone, swap SD cards, boot to TWRP (vol up and power till vibrates [or boot image from PC]) and flash what you need. Then click Reboot / Power Off, and swap back to your adoptive SD before rebooting phone. (This is what I do to flash ROMs on L02.) Hope it helps, PW.

Go to Settings / Developer options, toggle on Advanced restart (adds options to reboot to recovery etc from restart menu), close Settings, hold power button (note: phone must be unlocked), click Restart, select Recovery, click OK, and if flash was good it should boot to 'teamwin' screen.
