I also tried TWRP with stock TWRP L02 backup from here, still have black screen on boot. This is so freakin' weird, can't believe it wont go away.

Does it mean anything if the backup folder was different? the .zip had /sdcard/TWRP/BACKUPS/12d5701e whereas mine was /sdcard/TWRP/BACKUPS/43d4724c, so I moved the files into the one that TWRP could restore from.

I can flash some ROMs but they all boot to this weird half-black welcome screen, clicking the Arrow takes you to half of some screen about reading instructions that came with phone and I can see a skip button, clicking that makes screen go black. if I don't do that I can swipe down to see standard options for auto-rotate, GPS, etc but the Settings Cog icon doesn't click so it isn't much use. If I could force it to start in screen sharing mode or something maybe I could remote control it? I dunno, it's screwed is all I can tell so far. paper weight.

EDIT: okay I got into a working rom. Using TWRP recovery I was able to flash CARBON-hb72k.zip and boot into a working OS, still without a boot logo though!. Flashing from CWRP and fastboot and the other thing all failed or booted into unusable OS with every rom I tried. TWRP for the win, team win... hehe.

I still have that weird feeling that I want to restore back to L02 stock because Carbon has a few weird quirks (wifi slow, can't use Link2SD) but I better just leave it alone for a while I think. Already spent tens of hours on it.
[Android Q&A, Help & Troubleshooting] iTzSamm:
Alright, if anyone could help me that would be great. I've been having a ton of problems ever since the update (OTA) for the Y550, it failed. Ever since then I have had no wifi, sound, fast-boot (Huawei One, like where the phone turns on fast), data, service/signal, deciton of sim or basically anything. I just flashed a ton of ROM's and after a while of trying to fix it, guess what now all the phone does it go black screen after Huawei logo. The only way I can get into recovery is by doing "fastboot boot twrp.img". I've tried re-flashing it, I've tried everything. Now I can't even get into my phone, (because of black-screen). I've tried every rom, every feature, I even tried wiping my SD Card and repairing file-systems. If I can flash anything or do anything or anything PLEASE HELP ME!

ps: I think my phone started doing it after I tried flashing the images from the L01 UPDATE.APP, like modem.img and boot.img, I flashed them all via TWRP in Images. If you are wondring my phone is L02, and is from New Zealand I think (Could be aussie.)

Thanks for reading, :confused: :mad: :fingers-crossed:!
[Android Q&A, Help & Troubleshooting] Turkey_shoot:
Try downloading one of the original stock ROMs from links at the start of this thread.

Then install using CWM via fastboot boot (not flash, unless you want CWM on the phone) as you did above with TWRP.

You will need to make sure you choose the correct menu options from the chinese-only parts of the CWM menu.
[Android Q&A, Help & Troubleshooting] tezzar:
wow I had exactly the same problem (almost) and I have L02 from vodafone australia. The only way I fixed it was TWRP recovery and Carbon ROM, see my posts for more info. It took me a long long time to work out and I thought it was bricked.

Mine broke after editing the boot animation in /cust/ using ES File manager root.

You can't install stock roms, they just fail. Carbon ROM by Hb72k was the only rom I could install and only using TWRP (fastboot flash recovery).

If you rotate your black screen after boot you might see half a screen but you can't do anything useful.

btw: isn't "fastboot boot twrp.img" meant to be "fastboot recovery twrp.img" ? I forget, I went through lots of crap. This was my command

fastboot flash recovery "C:\y550\TWRP_Y550_20150821_recovery.img"

[Android Q&A, Help & Troubleshooting] Turkey_shoot:
OK, scraping the bottom of the barrel here.. but maybe one of the ROMs you flashed modified the sizes of your partitions, making them the wrong size for restoring stock rom?

You might be able to check partition sizes against specs, or maybe against other people's phones. I don't know how to do this with the Y550.

Something is get in between the voice app and the browser app I guess. I'm pretty sure it used to work. It just means voice search is empty, it does actually hear the voice and translate to words but wont put the words into the box.

Google Now voice search works but I don't think I want that installed.

edit: It was just the defaults, had to clear default handler for all browsers installed in app manager then it asks which browser to search with and it works if I choose Chrome instead of Browser.

This version fixes SD-EXT - now you can format your SD from Advaced>Partition SD Card and also backup/restore it.

I cant do anything about the time being set incorrectly, as it's caused by android not saving the correct time settings (read here)

And I dont know what's with the battery percentage. It shouldnt be a huge issue anyway, since you see the battery level on boot, it only switches to 0% when the level changes...
