Just remembered, HiSuite has Update Firmware function for those on stock, that should search for and install latest official firmware. If it works, reinstalling this way should fix your problems if you have no physical memory (emmc) issues, which unfortunately seems likely to me:

Hi guys. I have an y555, I want to root it for eliminate unnecessary things and free up space. I asked for the code to unlock the bootloader to Huawei but they did not give it to me. How can it be obtained? I just need to root, I do not want to install customs roms. thank you

If you have B247 or earlier stock ROM you can still unlock with DC Unlocker for small fee. See my post #6381 here:

Unfortunately it appears it may now be impossible to unlock bootloader if you have applied updates since, and have B249 etc. (Thanks Huawei :( ) See info in post 6510 here:

https://xdaforums.com/android/help/to-root-huawei-y500-t2923318/page652

Edit: I'd recommend trying LOS14.1 if you can unlock bootloader. Its pretty much bug free now and smooth, and you'll benefit from integrated adopted storage (great for Y550 - use fast SD card), up to the minute security patches, and other improvements of Nougat over KitKat. All the best, PW

Are there news on android 8 ?
[Android Q&A, Help & Troubleshooting] pndwal:
Seems nothing new for Y550 yet.

As reported here, [MENTION=4479868]desalesouche[/MENTION] got LOS15.1 to compile without errors, but when flashing we get error 7 in TWRP: "E1001 failed to update system image" (See page 637). - [MENTION=6726815]Saint_13[/MENTION] and myself have also tried to flash (I've tried with FlashFire too) and get same errors. And sadly, [MENTION=4479868]desalesouche[/MENTION] has not been active on XDA since Nov 2018, so it seems he isn't trying any more.

Of course, our LOS ROM is an unofficial cherry ROM, based on official che1 cherry ROM for Honor 4/4X etc, so we can only get Oreo or Pie after the officially supported devices have these ROMs to port from.

We have had base official LOS 15.1 (Oreo) cherry ROM for Honour 4/4x for some time now, and this has progressed to unofficial 16.0 (Pie, experimental / beta).

Interestingly, our base ROM dev, [MENTION=5091734]dianlujitao[/MENTION], also produces ROMs for cherry (che1) devices in other flavours too, including official Mokee ROM, which has recently progressed to MK 9.1, based on Android 9.x Pie, and this is reportedly working much better than unofficial LOS 16.0 (Pie, experimental / beta), possibly as it necessarily has more up to date sources. This now has nightly releases, and there are up to date 8.1 releases too.

I'm hoping someone will try again to port one of these O / P cherry (che1) ROMs for Y550 now that more options are available. Who knows, the Mokee ROM may also play nicer with Y550. :)

And many thanks [MENTION=5091734]dianlujitao[/MENTION]. :good::good::good: PW.

Just a quick addition to the buglist: one is not able to unlock the network from LineageOS builds, factory firmware is needed to be reflashed to do it, but after that LOS can be reinstalled and used. Just some inconvenience (involving losing all your settings) once in the phone's life.

Don't know what is exactly behind the issue: the unlock window comes up when a new SIM card is inserted, you type in the code, the screen says "requesting network unlock", but nothing happens. (Whereas it returns the result quite quickly on the factory firmware.)

Hi.

Is this better?

I ask because the 4XQWT_LP_Modem Baseband (stock Lolipop Honor 4x Qualcomm Wireless Technology modem) from [MENTION=5091734]dianlujitao[/MENTION]

has worked for all che1 / cherry devices with custom CM / LOS ROMs since 2015 (other than some Indian and Chinese variants, for which 4xdx_lp_modem.zip, and c8817d_modem.zip are available). I assumed this would also be signed.

Regards, PW
[Android Q&A, Help & Troubleshooting] fwiep:
No certainly not better. It's probably the same file, only signed.

Apparently not - when I tried to flash it using TWRP, the updater-script complained about it not being signed.

So I searched for and found a way to sign it myself (using LineageOS keys already on disk).

That's all.

Kind regards,

That's interesting. Would unmodified file not flash successfully for you (despite error)?

I just reflashed original file using both latest official and latest unofficial TWRP on Y550_L02 and can't duplicate the problem. The only errors are non fatal: Skipping Digest check: no digest file found, and Updating Baseband for che1_CL20 (one of several Honor 4x models for China).

Further to my last post re. frustratingly bad performance using LOS14.1 custom ROM on our three Y550 phones in daily use: Apps become laggy and unresponsive, scrolling becomes stuttery, and frequently apps lock up completely and need restarting after minutes of use:

I said "but when I enabled RAM Management Fixes by crok, we had an INSTANT FIX! - no more app freezes, lagginess gone. :)"

Actually, when I enabled RAM Management Fixes by crok, we had instant improvement - app freezes, lagginess were reduced and seemed to be solved for a while, BUT STILL OCCURRED.

With further investigation, I discovered the problem actually stemmed from Magisk root. Not sure what component, but with a full cleanup and unroot the phone behaved perfectly again - app freezes, lagginess were gone completely at last.

Next, I fully reinstalled Magisk and modules, and all is still good. :)

Then I disabled RAM Management Fixes by crok, and found there is now NO DIFFERENCE, so I'm concluding that when settings are messed up on a device this mod can and does improve things, but with a normally working Y550 device it offers NO ADVANTAGE. Sorry if previous info posted was misleading :silly:

Edit: I thought I'd re-enabled Magisk modules, but new installation was actually set to Core Only mode. This is what resolved lag and app crash issues, and turning it off to enable module use immediately destroyed performance, even with all mods toggled off (deactivated) :( .

I'm not sure when this started, but seems many have had the issue for several Magisk iterations, and have found no solution other than to sacrifice modules and use only basic core-only root functions. - There is very little info on official Magisk threads, but heaps of reports and analysis elsewhere, with no other solutions. (My guess is others with issues have low Ram devices like ours. Issue could also be associated with adopted storage use.)

This is a real shame as many mods are very useful. Guess I'll just have to find TWRP flashable alternatives for YouTube Vanced. Viper Audio, Call Recorder etc etc :( .

Summary: Sadly, the only solution for lag and instability with Magisk root on Y550 for now is to RUN IT IN CORE ONLY MODE. Let's hope [MENTION=4470081]topjohnwu[/MENTION] works some magic and fixes it, but don't hold your breath... End Edit.

Just thought I'd pass on this fix as it was sorely needed, and should help others experiencing these problems.

Did you try 24ky's Triple Swap (/data, /system, /cache) init.d script (https://xdaforums.com/showthread.php?t=2145133)? In y550 we have 185 MB of NAND sitting idle in /cache, and even if reclaiming this as swap space brought not too much in performance improvement even this little would be better than laying 185 MB to waste.
[Android Q&A, Help & Troubleshooting] pndwal:
:good:

FWIW, I'd at least take a look at the Magisk mod repo (Magisk Manager Downloads; click each for details, XDA threads, etc). - I think you can load manager and see repo without flashing Magisk root.

There are now myriad mods (incl. essentials like busybox), all systemless, and something for everyone from audiophile's (you?) to gamers, power users and photography buffs. And many more on XDA not in official repo for 'sideload'.

Some mods make the claims of snake - oil merchants, but most simply do their job well. All are easy to disable even if left installed (good for evaluation); simply toggle of in module list, and restart. If any cause boot problems, they can be disabled individually in TWRP using Magisk Manager for TWRP.

The modules are a major reason to use Magisk aside from basic root features. Many xposed mods are replaced by these too. PW

Many thanks - that's very interesting. I'll be sure to look into that soon.

No 8.1 or 9.0 from FWieP

Dear all,

I would like you to know that I will not be able to provide an Android 8.1 or 9.0 custom ROM for the Y550 devices. For any device, actually. I will however keep on building the monthly 7.1.2 updates - as long as LineageOS officially supports that version.

Most important part of this ROM development would be hacking around a custom kernel. Over the past few months, I have tried to read into that, but it is too much information to assimilate. It would take me a VERY long time to understand what needs to be done and know how to do it.

[MENTION=4479868]desalesouche[/MENTION] and others have built a custom kernel for 7.1.2 (which I use each month in my updates). There have been efforts by him to make the jump to 8.1, but they have stopped. It seems, he can no longer be reached (publically or privately). I hope he is well...

If someone else would like to try their best, please do! I'm ready to test any 8.1 or 9.0 on my Y550-L01.

EMMC and other failures are often associated with noticeable overheating on phones with older snapdragon SOCs like SD410, and overheating occurs even with stock ROM on Y550. All best, PW.
