Hi dear friends :)

I know it's unrelated (i think not completely unrelated! :D) to Y550 , but i need your help and support.

we developed an android game, if you like you can download and share it with your friends and support us. my goal is 1K downloads on google play.

Thank you for this ROM.

Tested calls, WiFi, Bluetooth, camera... It works perfect for my daily use.

This is what I'm most grateful for.

Would you share your

files? I hope to learn from them and possibly build a ROM myself.

In any case: Thank you very much!

here is attached my roomservice.xml. only tiny change are needed to convert cherry device tree for y550.

make sure to change ro.sf.lcd_density=320 to 240 in system.prop

to change in boardconfigcommon.mk 720*1280 to 480*854

to change kernel path:

TARGET_KERNEL_CONFIG := cm_hwY550_defconfig

TARGET_KERNEL_SOURCE := kernel/huawei/y550-vid

in msm8916.mk; do that change also:

# Boot animation

TARGET_SCREEN_HEIGHT := 854

TARGET_SCREEN_WIDTH := 480

and change xhdpi to hdpi.

last thing, add the focal testlib file (attached)extracted in kernel under drivers/input/touchscreen/focaltech/
[Android Q&A, Help & Troubleshooting] fwiep:
Thanks to your detailed instructions, the first build succeeded immediately.

I made a backup using TWRP, copied it to safety and then tried to flash the image...

TWRP refused and complained that the image was not targeted at the current device (Y550-L01).

So, I modified /device/huawei/cherry/BoardConfig.mk so it reads:

TARGET_OTA_ASSERT_DEVICE := c8817d,g620s,C8817D,C8817E,G621-TL00,G620S-UL00,G620S-L01,Che1-CL20,Che1-L04,Y550-L01

If someone wants to build for L02 or L03, they probably should be added here too.

Thank you very much!

[Android Q&A, Help & Troubleshooting] MajingaZetto:
Can you fix the alarm clock?. It doesn't work if the phone is turned off.
[Android Q&A, Help & Troubleshooting] x.akshit:
There's no such phone who's alarm clock works after its been turned off. If you mean to say screen off please let me know.
[Android Q&A, Help & Troubleshooting] pndwal:
This was a common feature on older phones. On Android, some stock ROMs have it working - phones like Alcatel, OnePlus and Huawei, but reportedly never Samsung or many other brands.

On OnePlus for example, to activate the feature you set the alarm and click the arrow that shows drop down options, then check "wake if device is powered off". Apparently devices like this will power up about 2 minutes before alarm. Other phones, eg Huawei Mate 9, apparently have hardware ability to sound alarm from system clock even when powered down. These apparently implement a check box on Power Off screen to 'keep alarm active after power off'.

There are a number of dedicated threads on 'Alarm on Powered Down device' feature and related problems on XDA.

Sady, most users seem to complain that they loose this ability when installing custom ROMs. I'm not aware of it working on any phone with LineageOS.

[MENTION=7569544]MajingaZetto[/MENTION], have you ever had this feature working on Y550, or on LineageOS? PW.
[Android Q&A, Help & Troubleshooting] x.akshit:
Um there's a new feature of Schedule Turning On in which you can turn on/off your device at specific times
[Android Q&A, Help & Troubleshooting] pndwal:
Ok, guess clock or alarm app could utilise this quite easily then. Where is that found? Feature in LineageOS? PW
[Android Q&A, Help & Troubleshooting] x.akshit:
Unfortunately it has been discontinued after 14.1 update
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks, yes, seems not new - existed in Android 6. Demonstrates hardware ability to wake up system for alarms etc however. PW.
[Android Q&A, Help & Troubleshooting] rudolfm:
The "alarm switches phone on" feature is present on some phones with Mediatek boards. These phones have a feature in the settings of the stock Rom which allows poweron/off at specific times. As they can switch themselves on at a specific time, the alarm can also switch it on. I have/had several phones and tablets which could do this, from Acer, Alcatel, Mobistel and others.

As this is a specific feature, it depends on the Maintainer of the LOS for this device. This is not a general Android feature, it is specific to the Kernel.

I don't remember the Y550 having this feature.
[Android Q&A, Help & Troubleshooting] pndwal:
Sounds about right, however . . .

I can confirm Y550 on stock ROM does indeed do this. (Just tested this twice on my spare Y550 - bootloader unlocked but still on stock). Phone powers up 1 minute before a set alarm without any special settings (so clearly some phones like Y550 with Qualcomm chipsets have this ability too). This surpriseed me, but clearly this is one model where users may miss this previously implemented feature when moving to custom ROM.

Would be nice if it could be brought back on custom LineageOS ROM as [MENTION=7569544]MajingaZetto[/MENTION] requested. As suggested, this may require kernel support / fix. PW.
[Android Q&A, Help & Troubleshooting] desalesouche:

Hey guys, I'm trying to fix Y550

It was bootlooping so I somehow unlocked the bootloader and flashed TWRP and I tried to flash a rom

but it just doesn't boot, it doesn't matter which rom I try it just bootloops and never boots into the rom

Can you help ?:highfive:

[Android Q&A, Help & Troubleshooting] x.akshit:
Okay so first of all I will let you know why a phone gets bricked-

>Corrupted Rom

>Some system files got deleted

>Rooting

>Modding

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

MY CASE

I always keep two phones with me like one for my experiments and one as a backup. In this case I'll be talking about my LYF WIND 3 with SNAPDRAGON 410 that got bricked.

>Actually I was trying to install TWRP onto that phone but first I had to root it, and due to the upgraded android security, I wasn't able to do via KingoRoot so I tried I-ROOT and it did the job but instead of kingo-superuser I got some ****ty superuser so i tried granting permission to the actual SUPERUSER and while doing so I accidentally double rooted my phone (First with I-ROOT and then with KingoRoot), which was kinda stupid, so it just deleted some system files and my phone wouldn't boot after that. It just got stuck on the boot logo.

>The second time I was trying to replace the boot animation and logo but did something wrong so the same situation arose again.

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

CURE

So my phone uses a Qualcomm CPU so i just guessed I'll flash it again.

*After Intense Googling*

I found this software QFIL (Qualcomm Flash Image Loader)

I downloaded this file and the drivers for my device. *Google it you'll find for yours too*

Then I downloaded the Stock Rom for my device *Google it again*

Now I just went over to Flat Build in that software and loaded the firehose file and the rawprogram.0 and Patch.0

Now I had just put my device in Download Mode (Volume Keys and Power Key)

Connected via USB and it detected it and then just clicked on DOWNLOAD

It takes about 5 minutes.

After this your phone gets good as new (Unroot, Full Reset)

[Android Q&A, Help & Troubleshooting] DahakePL:
But dload says some stuff like oemsbl version list check error
[Android Q&A, Help & Troubleshooting] pndwal:
Trying to understand what happened here. Did bootloop start after trying system update, or did you try any software that alters, or flash, any partition other than user data? Or were you simply using phone normally? PW.
[Android Q&A, Help & Troubleshooting] DahakePL:
I got the phone with bootloop, I tried flashing stock rom but no luck, errors everywhere. So I unlocked bootloader and flashed TWRP and then a custom rom.

Nothing changed, bootloop is still there. I don't know what to do. Dload isn't functional, it just shows multiple errors.
[Android Q&A, Help & Troubleshooting] pndwal:
Ok, so this is a slightly better scenario than if just bootlooped with daily use (which would indicate phone probably developed physical memory problem). In your case it's likely previous owner messed with critical partitions or experienced bad flash (unlocked bootloader can return to locked in this case too).

I recommend you go to http://huawei-firmware.com/phone-list/huawei-ascend-y550, click a link for your model, download firmware from here, and ensure you follow instructions on the linked page exactly to perform dload.

I see you're in Poland. Is this phone L02? (Check sticker behind battery.) If so, click and use New Zealand firmware listed.

If dload using extracted Update App from this download fails, we can look at methods to rebuild emmc. Let me know how it goes, and device model. PW.
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks for info in private messages. Understand dload from link above doesn't work. Model is L01. So unless physical memory is damaged (quite likely), seems emmc rebuild is needed.

I have no practical experience with this, but research I did is in post #6043. It involves using QDLoader 9008 software. Guide, and also link for rebuild file specific to Snapdragon 410 (ie prog_emmc_firehose_8916.mbn) posted here.

Try this method, or [MENTION=9078544]x.ak****[/MENTION]'s method in his reply to you above, or both. QFIL (Qualcomm Flash Image Loader) may be a better / later software solution, I'm not sure, but it appears he succeeded in fixing emmc on phone with the same chipset as ours, while others have failed. Probably firehouse file in my link will be good for either solution.

If emmc rebuild succeeds, you will likely still need to repair phones unique numbers (will probably now have generic ones, or none), including IMEI, MAC-addresses for Bluetooth, MAC-addresses for Wi-Fi and SN to ensure SIM operation, WiFi, Bluetooth, etc all work properly. I can point you to software needed for this if all goes well (unless above software includes options for retrieving / restoring these also - let me know). All the best, PW.
[Android Q&A, Help & Troubleshooting] DahakePL:
I just told my customer that the internal memory is broken, this phone isn't worth that much effort especially looking at it's price.

Thank you very much for trying to help me, I really appreciate it.
[Android Q&A, Help & Troubleshooting] pndwal:
If any of you are still interested in fixing broken emmc on Y550, have a look at post #6096 from [MENTION=9078544]x.ak****[/MENTION].

It appears he succeeded in fixing emmc on phone with the same chipset as ours using QFIL (Qualcomm Flash Image Loader) software.

See my post #6101 also. These may help you. PW.
[Android Q&A, Help & Troubleshooting] pndwal:
My post #6100 has good alternative link to official ROMs for all models.

As I mentioned in my post mentioned, post #6043 contains links to needed firehouse file and others, plus tutorials. Have a look.

Not sure re. rawprogram.0 and Patch.0 files. If they aren't there I can look too, but [MENTION=9078544]x.ak****[/MENTION] may be be better able to help with these. PW
[Android Q&A, Help & Troubleshooting] x.akshit:
yup brother im here to help.......but i am sure that you've not downloaded the correct firmware file for flashing!

Or is your device using a snapdragon 400/410/625/201??
[Android Q&A, Help & Troubleshooting] pndwal:
Yes, Y550 is snapdragon 410, same as your successful emmc rebuild, which is why I feel your solution may be of real help to others here.

As mentioned, I found prog_emmc_firehose_8916.mbn for this, but no-one I know of with bad emmc was successful using QDLoader 9008, so I suggested they try your solution with QFIL (Qualcomm Flash Image Loader) as it may be a better / later software solution that has succeeded with the same chipset as ours.

Hope you can help [MENTION=8240343]TheBlackJJoker[/MENTION] with rawprogram.0 and Patch.0 files. I'm not sure what they are / do. PW.
[Android Q&A, Help & Troubleshooting] x.akshit:
rawprogram and patch files are for directing the software to download the firmware into correct partitions.
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks. Will they need to be specific to snapdragon 410, or Y550? PW
[Android Q&A, Help & Troubleshooting] x.akshit:
For every FIRMWARE all are different!
[Android Q&A, Help & Troubleshooting] pndwal:
So should all these files are found in / extracted from official stock ROM? Or will special 'service' ROM be needed? Or are they found separately elsewhere?

Is Flat Build a folder? Thanks, PW.
[Android Q&A, Help & Troubleshooting] x.akshit:
Flat build is a type of flashing and use the rom specified for your device!

All the files are in the extracted folder only
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks [MENTION=9078544]x.ak****[/MENTION].

[MENTION=8240343]TheBlackJJoker[/MENTION], please read last few posts from x.ak****.

Seems you simply use Flat Build type flash in QFIL software, and point it to folder containing extracted official stock ROM, which should contain all files required.

I think the ones QFIL needs to find to start rebuilding emmc, from my research, are specifically named prog_emmc_firehose_8916.mbn, rawprogram0.xml and patch0.xml. (ensure the last two are from official stock Y550-L0X ROM.)

Hope this helps. Let us know how you get on. PW
[Android Q&A, Help & Troubleshooting] pndwal:
After successful emmc rebuild did you need to repair phones unique numbers contained there? (Ie: IMEI, MAC-addresses for Bluetooth, MAC-addresses for Wi-Fi and SN to ensure SIM operation, WiFi, Bluetooth, etc all work properly).

Guess your unique numbers may not have been corrupted, especially if you didn't wipe emmc completely, but can you tell me if QFIL software includes options for retrieving / restoring these numbers also? Or did you use 'qualcomm smartphone write imei tool', or something else?

Thanks, PW.
[Android Q&A, Help & Troubleshooting] x.akshit:
If you've installed QPST all these softwares will be included along with QFIL!
[Android Q&A, Help & Troubleshooting] pndwal:
Good tip! But did you need to restore any numbers, or were they intact? PW

Are you flashing Magisk 16.0? PW.

Additional info:

Consistently, official twrp is the only one that can display Adoptive Storage, (I guess it correctly uses encryption key at data/misc/vold), hovever 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.)
