Everything Huawei Y550 - Root/CWM/TWRP

[Blank tape]

Yep I've the same problem, error message when trying to flash lineage-14.1-20210803-UNOFFICIAL-y550.zip.

I thought fwiep fixed that but as I never tested that or subsequent versions I can't confirm the fix works. Finally, taking a looking at the most recent zip and the fix itself it does something different to what I suggested so I'm guessing not. Sorry to provide such late feedback Frans!

Anyway, I worked around the problem with a setprop command in adb shell:
setprop ro.product.device Y550-L02

This must be done before an install is attempted. It seems values are cached.

FWIW, I used twrp-3.3.0-1-y550 back then.

To pose a question myself: Is there a way I can use to return the phone back to B240 stock. B247 changed the boot process in such a way that while flashing TWRP in fastboot appears to work it does not replace the stock recovery.

Did you confirm you have 3.1.1?... How are you installing the twrp?... Are you first extracting the .img file, then flashing that to recovery partition as .img? PW

Unofficial TWRP 3.1.1.0, Dec. 16 2017 by desalesouche ===> Post

That is the correct TWRP file above; it is a zip file, not img.

Did you confirm you have 3.1.1?... How are you installing the twrp?

I installed the above TWRP 3.1.1.0 using the zip file install method in my current installed TWRP on my phone so via TWRP.

Are you first extracting the .img file, then flashing that to recovery partition as .img?

Where do I extract the img file from?

My assumption is to extract the recovery image file from your latest custom ROM, and then flash it to either my boot or recovery partion on my phone using my current installed TWRP on my phone. Is this correct.

Then flash your latest custom ROM.

No, it's only uploaded as a zip... Extract the img file and use that.

Did you confirm you have 3.1.1?... How are you installing the twrp?

I installed the above TWRP 3.1.1.0 using the zip file install method in my current installed TWRP on my phone so via TWRP.

Does the splash screen confirm you now have 3.1.1_0?

Via current twrp yes, as zip no ... Change flash type to.img and flash extracted.img file...

Are you first extracting the .img file, then flashing that to recovery partition as .img?

Where do I extract the img file from?

From the zip archive...

My assumption is to extract the recovery image file from your* latest custom ROM,

Does it include recovery?

and then flash it to either my boot or recovery partion on my phone using my current installed TWRP on my phone. Is this correct.

Correct method via TWRP is flash recovery.img to recovery partition generally for our device, never to boot partition...

Then flash your* latest custom ROM.

Can flash ROM or recovery first... Order doesn't matter afaik.

*ROMs are from @desalesouche / @fwiep... PW

Blank tape, pndwal, fwiep....

Guys, many many thanks for all your input these last few weeks and days.


Without your help, I would never ever been able to transform this old phone into what it is today.

My kid is over the moon.

We have left one as stock, and the other in custom 7.12 format.

pndwal your latest custom ROM works a treat. 7.1.2.

Any chance of 8.1 in the future.


Took this old dog a while to get it all working, learnt a bit myself.

Cheers fellas.

Take it you got twrp swap working then...

Again, ***ROMs are from @desalesouche / @fwiep*** - not mine!

Any chance of 8.1 in the future.

Most likely not... This ROM is / was a port from Cherry/ Honour 4/4x by @Blefish. @desalesouche tried hard to unify Y550/Cherry (Cherry got LOS 15) but wasn't able, and we haven't heard from him for some time...

@fwiep's updates basicy build with the current security patches and a few other improvements from Google, LineageOS and his own kernel fixes, etc...

This may depend on xloader version of both (can't roll back to earlier) as seems Huawei started implementing anti-rollback with this device... I read reports of several issues for B249...

Nb. Some have permanently bricked their devices (no methods to restore work) after rolling back to a ROM with older xloader, or flashing a ROM with different xloader.

WARNING To Others who want to customise Y550:
It seems Huawei updated XLoader on B249 and later in a number of regions. Problems relate 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, and other patches that break root (though magisk now has a workaround requiring manual creation of boot.img), as well as problems using TWRP and custom ROMs (which have been made using lower XLoader), and unlocking bootloader with legacy (the only) methods.

But are you sure recovery isn't just being replaced on system boot (also common practice)? ... Usually booting immediately to twrp after initial installation allows twrp to install it's fix for this, or simply installing magisk... Still, it could be a bootloader thing as similar issues are reported for B249... PW

Yep bud, got the unzipped 3.1.1.1.0 TWRP working.

I did a full format of the phones drive in TWRP 3.5.1_9-0.

I then installed the TWRP 3.1.1.1, then installed the latest ROM without issue.

A big thankyou to desalesouche and fwiep for providing the custom Rom's.

I've not installed the zipped modem update yet, is it worth it, will it enhance anything on the phone.

I have noticed even though the custom ROM package is so much smaller than the Stock ROM package. It does not increase storage space on the phone itself very much does it.

You will have call / network / LTE issues on post Android 4.4 ROMs if you don't... Your call...

No... You should review my notes on this / setect appropriate GApps package / update Gapps or systemise updates regularly / use adopted storage... This was debated, but for me it's essential on Y550... PW

I will install the modem then.

I have not installed GApps, only for the reason as the four apps needed, i have the latest apk's, so I did not see the point.
Would you disagree?

As you say, it depends on what you want / need...

For me personally, I like / need to have a number of Google apps incl. Chrome browser, Webview, Maps etc, Play Store access to apps / updates, Safety net API (in Google play services) working for bank app, etc etc...

Moreover, Android w/ proprietary Google apps may be fine for a TV box or an automobile interface, but as Google's mobile OS a Smartphone is pretty much crippled (or dumbed down at least) w/o their proprietary offerings in my view... (I note that many Chinese install custom mods / ROMs just to obtain GApps otherwise not available to them!)

Others have a different view... Each to his own... PW

I installed the modem zip.
Got a big problem though. I never tried to make or recieve calls prior to installing the modem zip, but I tried to call the phone tonight and i cannot recieve calls or make calls?
Any thoughts.

I just did a TWRP restore back to stock rom. Same problem no incoming or outgoing phone calls on stock rom restore.

Has the modem update caused an issue with L02?

Something not right.

Baseband is 11060045

Mobile network state - disconnected

Pasted:
"All New users need to update (flash) modem partition. It is not updated with ROM. Only need to do this once. Flash 4XQWT_LP_Modem Baseband Version: 11060045 "Recomended for Lollipop And Marshmallow ROMs", but needed for everything after KitKat. Download from Development thread above, see Modems, post #2."...

You should flash back stock modem for stock KitKat.

May need to set network manually by going to settings>more>Cellular networks>Preferred network type>

Check set to GSM/WCDMA/LTE or something appropriate for your region... (just set to LTE phone may not receive calls) Nb. VoLTE is not available for Y550.

May need to reset network connections too, check SIM is recognised etc... PW

Appologies for my post; it's the easiest way to outline my experiment and relay the results to you.

Three different sim cards/numbers all on this network - https://www.o2.co.uk/coveragechecker

Two phones

Phone One - Huawei Y550 - Unlocked/Rooted Android Version 7.1.0

Phone Two - Samsung GT S7275T - Unlocked/Rooted Android Version 8.1.0


Prior to rooting phone one and flashing the new zipped modem into Phone one; Sim card 3 could make and recieve calls in phone one.

I am not sure if I could make and recieve calls in phone one after rooting phone yet prior to flashing zipped modem into phone one.

The Sim card 3 was present in Phone one during the rooting and flashing modem process of phone one.

Could sim card 3 have been corrupted during rooting and flashing of phone one yet it works fine in phone two.


Sim card 3 in phone one cannot make or recieve calls and I am getting -

GSM Call settings/call forwarding/Voice - Network or sim card error

GSM Call settings/ - Network or sim card error


Phone One

Sim 1

CDMA Call setings are blanked out.

GSM Call settings are fine.

Sim 2

CDMA Call setings are blanked out.

GSM Call settings are fine.

Sim 3

Bought another L01 arrived today from eBay. So got a L02 on 7.1. A L01 on stock. Today's arrival my 3rd is going to 7.1.
I'll unlock the bootloader. Then custom it. There is a charity on eBay UK selling them Brand new at £27 so about $50 unblocked to any network. I just like the phone and for $56 rooted it suits my need's. Sentimental value also.

If you have some firmware not already on https://files.fm/u/gdmxigp please upload it. Others wiser than me would know the best format. Personally, I would use adb to copy images of all the partitions since I know no better.
