Goodoh.

If you're adventurous you could try to compile 15.1. [MENTION=4479868]desalesouche[/MENTION] now has no errors and succeeded, but it won't yet flash. (error 7 in TWRP - "E1001 failed to update system image".) Regards, PW

7.1.2 update

Thanks to the LineageOS-developers and [MENTION=4479868]desalesouche[/MENTION], this is today's build containing the November-2018 security patches.

Recent LineageOS changes: https://download.lineageos.org/cherry/changes/

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

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 June-2020 security patches

Known bugs:

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

- the setting to disable battery optimization for an app does not survive a reboot (for me, WhatsApp should not be optimized to enable backup over WiFi at night)

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

Yes, I am eager to try compiling LOS15.1. Will have a go as soon as there is more time :)

For now, I am very pleased that our Y550's have yet another month to live in relative digital safety.

Kind regards,

FWieP

hi all.

kernel wifi side need to be updated. it might help to fix the Known bugs:

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

kernel would need to be updated to that point: https://github.com/LineageOS/androi...mmit/cbbfd0d954390b417e6efa13ad8b9977b30cc0ac

'caf/prima/LA.BR.1.2.9_rb1.30' for los14.1 and more for los15.1

and actually kernel is up to 'caf/prima/LA.BR.1.2.9_rb1.26'

[Android Q&A, Help & Troubleshooting] lin_ux:
It could be interesting, but not something I'd be willing to play with.

I've caused myself more pain than gain when messing with system partitions in the past, the most I'd consider doing now is to shuffle a few of my user apps into the system area if I ever needed more space, which luckily I don't.

Unfortunately 4GB is not really much space in total, so even if it were possible to repartition, there would not be a huge increase in user space due the total area being so small to start with. Perhaps if the phone had 8GB in total then it might be worth it, but then again, there would also be less need because the user space would be bigger too anyway. Don't you think?

Keeping it on a low fat diet is probably the only way to survive....
[Android Q&A, Help & Troubleshooting] mac_d4di:
Yes I agree, not something i would do on my own either,

So im running cm11 still, and trying to work out the battery drain issue, but how can i move apps to sd card, I read that the option is gone on kitkat is there a way to renable it in some way as that could be a deal breaker for me.

On stock I had the option and had link2sd setup and working well for last couple of months
[Android Q&A, Help & Troubleshooting] patrik.KT:
I dont think there is a way to repartition it, but you can convert some user apps as system apps. AFAIK, titanium backup has this function.

About the battery drain issue, could someone post the battery usage from settings>battery? If its not available, then install a 3rd party app, such as better battery stats.

[Android Q&A, Help & Troubleshooting] patrik.KT:
Connect your phone in debugging mode (enabled by default) to a computer with adb installed and use this command:

adb shell pm set-install-location 2

This should set the default install location to sdcard (only refers to apps that can be moved to sd). To revert it, just change the 2 to 0 (zero) and execute the command one more time.

Yes, it is on stock rom, not CM11, sorry.
[Android Q&A, Help & Troubleshooting] patrik.KT:
Yeah, cm11 cant move apps to sd. But, its quite easy to setup an sd-ext partition. Just format your sd (if you havent done it yet), install Mounts2SD from play store, remount /system as rw (before starting M2SD!; can be done by "adb remount" or apps such as ES File Manager), launch M2SD, install script from application settings and reboot. You should have your apps on sd-ext after this :)
[Android Q&A, Help & Troubleshooting] dwane3:
patrik.KT,may be you will update cm11 with app to sd inside function?
[Android Q&A, Help & Troubleshooting] patrik.KT:
Okay, here is my brief tutorial on how to create and use the ext-sd partition:

Before you begin

* Backup your CM11 ROM, in case something goes wrong

* Make a backup of your external SD card, as the partitioning will fully wipe it! And dont forget to backup hidden folders, such as .android_secure.

Step 1 - Creating SD-Ext partition

Method 1 - Using TWRP Recovery (recommended)

1. Flash TWRP recovery (if you dont have it)

2. Reboot into recovery

3. Go to Advanced, then Partition SD Card

4. Enter the EXT Size as you wish (I formatted mine as 5GB fat and 2.7GB ext4 sd-ext)

Optional: if you need swap, set your desired swap size. If not, just set it to 0

5. Select EXT4

6. Swipe to partition

7. Restore the SD card contect from the backup you made earlier (and dont forget the hidden folders!)

...And you have successfuly partitioned your SD card. Continue to Step 2

Method 2 - Using minitool partition wizard

1. Watch this video

2. Restore SD card backup

Step 2 - Installing Mounts2SD

1. Install Mounts2SD from Play Store or this thread

2. Mount /system as RW by using this adb command from your computer:

adb root
adb remount

(you might get an error with "adb root", so go to Settings>About this phone, click on build number 7 times, go back, open Developers setting, click on Root access and select "ADB" or "Apps and ADB"). Alternatively, you can mount it as RW by using a 3rd party app, such as ES File Manager (swipe from left edge, click on Tools, enable Root explorer, then click on it, from the menu choose Mount R/W and set /system to RW)

3. Open Mounts2SD, tap the three dots and choose Application Settings

4. Install Startup Script

5. Reboot

6. Open M2SD

7. Click on the wrench icon

8. Enable items you want to push to sd-ext (Apps only by default, I enabled Apps, Libraries and Cache)

9. Reboot

And that's it!

Hope this helps you

i press ok and it says could not reboot recovery due to limited toolbox or something
[Android Q&A, Help & Troubleshooting] patrik.KT:
Because you did not mount /system as RW. Or you didnt allow root access for M2SD.

Some good news regarding no more bootloader unlock codes from Huawei:

New Cherry device G620S-L01 modder [MENTION=9557980]_benedict_[/MENTION] has confirmed we can still unlock legacy huawei devices this way. He unlocked bootloader with DC unlocker today and price is still 4 EUR! (funkyhuawei.club may be simpler (only need to send IMEI), but may be prohibitively expensive at 55 USD.)

This should be useful for new modders, allow more Y550 owners to join this community, and thereby be conducive to continuing development of custom ROMs for Y550, as well as other unofficial cherry ROMs (there are a couple) and official cherry ROMs (the development of which Y550 modders rely upon and benefit from). It seems all related cherry devices can be unlocked by DC Unlocker.

- Reminder to new modders: You need the onetime update for modem partition (baseband) when moving up from kk. Get it in Y550 'Development' thread, post #2. PW

[Android Q&A, Help & Troubleshooting] YuT666:
Hi,

got a Y550 some time ago (unlocked BL, Root, LineageOS 14.1 and it works very well.

But there is one problem... TWRP is gone. There is only the stock recovery. I tried to reflash the latest TWRP in fastboot mode and the flash was successful (there was a message). But after a reboot, the custom recovery is gone again. I flashed it many times, but it is always gone.

It seems, that the stock recovery always overwrites the custom one at restart.

Damn, what COULD be wrong?

Thanks.
[Android Q&A, Help & Troubleshooting] Saint_13:
what code you exactly use to flash TWRP ?!
[Android Q&A, Help & Troubleshooting] YuT666:
Well ...

fastboot flash recovery recovery.img

... and i received, that the flashing was successful. But after a reboot to the recovery, there is still the stock recovery.

Some people say, that it would only work, if you flash a custom kernel right AFTER flashing TWRP, so the stock won't overwrite the custom recovery.

But i can't find the 14.1 LOS kernel as a flashable standalone file (i don't want to flash an other custom kernel, 'cause LOS works great with the original one).
[Android Q&A, Help & Troubleshooting] pndwal:
Did you try to flash twrp image in twrp to see if it may sticks? (Put copy of twrp.img on SD card, Fastboot boot twrp.img (on PC), Go install, install image (SD copy), then select 'recovery' partition when prompted). I swap recoveries this way often. Immediately boot to recovery from reboot menu.

Several others have had this problem however. Read all page 594 this thread.

I still think latest Huawei update is causing twrp not to stick. (On other devices stock ROMs overwrite recovery unless booted to twrp first.) Flash not sticking or overwriting could be occurring. I notice last stock build I had was Y550-L02V100R001C346B247SP01 whereas those reporting problem have later (...B249SP01), so flashing older stock (downgrading), or restoring full older stock using dload method may allow flashing recovery again. (I realise others tried dload and it didn't fix, but I think they flashed B249SP01.)

Of course, you can restore 14.1 after flashing stock.

Tip: do full nandroid backup of 14.1 first (TWRP backup), then you can can simply restore from TWRP. Be sure to transfer backup off SD, especially if using adopted storage. Of course you can do this now; as outlined above, fastboot boot twrp.img command from ADB on PC will boot TWRP without flashing, allowing you to use all TWRP functions even before you can get TWRP to stick.

You could try this method first.

You can flash kernel from original 14.1 LOS zip. Its boot.img in the zip package. Simply extract it and flash img from TWRP.

Please report if this, or flashing older stock fixes this problem. Hope it helps, PW
[Android Q&A, Help & Troubleshooting] YuT666:
Thanks for your help, i really appreciate it.

I tried this method ... no luck. Still stock.

No luck too, so i've to give up. Don't want to try other things (not worth the time and it's hard to find an older suitable european stock rom, 'cause all links are dead). LOS works, so i've to stick with the stock recovery.

EDIT: Tried to downgrade to B246, but i always got a "update package's ext name error" ...

My old stock before flashing to LOS was:

Y550-L01 V100R001C00B250CUSTC432D001

And i choosed:

Y550-L01 V100R001C00B246CUSTC432D001

Again ... no luck.

All 3 methodes fail. Crap, this sucks.
[Android Q&A, Help & Troubleshooting] pndwal:
Yes, expected you'd need to flash lower version stock (B247 or lower). - Looks like Huawei added anti recovery tampering (dirty trick) in later system updates.

Have you tried dload method? (Uses extracted UPDATE.APP file pasted to dload folder in root of SD card.) This should get phone back to stock (even with locked bootloader!) I recommend you go to http://huawei-firmware.com/phone-list/huawei-ascend-y550 (the most complete / reliable archive of stock ROMs I know of), click a link for your model, download firmware from here, and ensure you follow instructions on the linked page exactly to perform dload. (Choose from LO1, LO2, LO3. Check sticker behind battery.)

Below is more info. that may help:

Hope you have more success with dload. :) PW.
[Android Q&A, Help & Troubleshooting] YuT666:
Well, thanks again, but i already tried the dload method.

I tried three different L01 stock firmwares (B246, B243, B239) for my L01 Y550 and copied the dload folder (including the UPDATE.APP) to the root of my sd card. After that i used the stock recovery to flash it ... and i always got the same error:

update package's ext name error.
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks for reporting.

It seems other Huawei devices have this / similar problems recently (since May/July deadlines for officially provided bootloader unlock codes passed), and that it relates to xloader.img updates to bootloader from version 0 to version 1 or version 1 to version 2 which prevents rollback to earlier ROM's using lower xloader versions (Nb #) and other patches that break root (though magisk now has a workaround requiring manual creation of boot.img). Some information in these threads: https://xdaforums.com/mate-10/how-to/beware-bla-l29c432b147-t3817241, https://www.xda-developers.com/huawei-update-broke-magisk-fix/

Nb # -This prevents DC Unlocker supplying unlock codes as this is only supported on earlier xloader versions and it is impossible to roll back officially after xloader update, and devices are bricked if non official methods are attempted. It also prevents unbricking with DC Phoenix etc.

No one knows for sure if these are further aggressive anti modding moves by Huawei, (these updates are also preventing rebranding and region changing, something done by many Huawei modders - there is also speculation Huawei is sending updates only to certain regions via OTA to curb this practice) but speculation is rife in magisk threads And elsewhere.

I suspect this is also affecting TWRP flashing on Y550 with post B247 stock, and it could be that DC Unlocker bootloader codes won't be generated if later updates have been applied also.

For now, workaround for Y550 users who have B249 etc stock ROM is to use ADB fastboot to boot to TWRP from PC to flash ROMs each time its needed. Also, get bootloader unlock code before updating past B247 (and avoid updating past B247). It will of interest to know if anyone on B249 etc can get code via DC Unlocker. PW
[Android Q&A, Help & Troubleshooting] YuT666:
My phone has B250 and an unlocked bootloader. So maybe the bootloader should be locked before "downgrading" to an older stock.
[Android Q&A, Help & Troubleshooting] pndwal:
Doubtful that would work, but you could try if you've kept the bootloader unlock code so you can reapply it. (Nb. This code doesn't change even when Huawei updates xloader 'switch' version, but update blocks methods of obtaining it from hardware such as DC Unlocker uses, or rolling back to a ROM that would work. - Those who rebrand however often need a new code as they are flashing generic values to their unique oeminfo partition and end up with different IMEI, SN etc.)

It would be useful if you could use method outlined on OP of Mate 10 thread in my last post (first link) to check which xloader your phone now has. If you do, I'll check version used in earlier ROMs to confirm whether Huawei updates have altered bootloader. However, since it looks like its not normally possible to flash traditional ROMs on devices where this has been done by Huawei (can't rollback) it seems more likely that 'patch 01' or something else in updated ROMs are affecting Y550 modders (Ie updates have altered critical partitions in some unknown way) as you have successfully flashed LOS. The inability to flash TWRP on updated devices may be unique to Y550 modders.

Can I assume you flashed LOS over B250 stock originally using ADB or TWRP booted from PC (or even QDLoader?). Or did TWRP flash and stick initially?

Kind regards, PW
