Well, what steps do I have to follow? Boot into redmi-recovery and then "wipe data" ?

Seems like a corrupted SystemUI. I had this similar issue a few times on my previous phone, a Moto Z2 Force. I only managed to fix it by making a hard reset through stock recovery. Don't know if there's other way with Xiaomi Phones..

Yup I experienced the same thing after changing to one of google's live wallpapers. I had to factory reset the phone through Twrp and now it's fine.

How to use TWRP to do a reset (instead of MIUI resetter)?

Just boot into stock recovery and format data from there.

It will do the same thing. You can use MIUI recovery. Either way I think you must do a clean flash to fix the system, which means losing your data.

I had to factory reset it to resolve the issue .

Factory Data Reset versus Factory Format

I would like someone to explain in detail the difference between "factory data reset" and "factory format"
You can do a factory data reset via the phone itself, or by using this code
*#*#7780#*#*
I've done this before, but it seems like a soft reset, I want something more hard. Something to totally swipe the phone clean, and reinstall everything fresh.
So I found this "factory format" code *2767*3855#
This totally wipes the phone, and reinstalls the firmware.
My question is, will using this second option reinstall stuff like avatar, and stock programs, or does it totally wipe everything off.
can someone explain the benefits and downfalls of the two.
yea you can go to settings/privacy/Factory data reset dirrecty from the phone if you want to hard reset/Wipe your Vibrant.

that didn't answer the question, I already said the first code is the same as doing the instructions you gave.
I was inquiring on a factory format, which is different.
Have you tried it(through the # command)? Or is that just what it says it does? Unless it downloads the firmware, theres no place that its stored on the phone, so I doubt it reflashes the firmware over again. I initially though maybe it would reformat and setup the /system partition, but it would need an img stored somewhere to flash it, and I doubt it does.
What it probably is, is just Androids naming vs Samsungs naming, and wouldn't reinstall any bloatware that was removed.

I did that last week, but booting the phone to recovery mode:
1. Turn off your phone.
2. Hold down the volume up and down buttons while turning the Vibrant on, which will bring you to the recovery mode.
3. Choose "delete all user data"
Once the phone boot up, you should have factory stock phone.

Thank you. I don't think people understand my question though.
What you are describing is the same as doing a data reset via through the phones settings, or using the first code I provided.
However, a "Factory format" is different. I'm trying to figure out what a factory format using the second code does.
again i'm asking about data factory reset vs factory format.
I believe what your after would involve one of 2 methods and no neither is a factory format or reset.
To completely reset the phone to stock all parts including radio and os files you need to use odin a pit file and a rom image.
If your ONLY needing to restore apps to factory/stock you can use the posted nandroid backups to restore.
Both methods are well documented but if you need help drop me a line or a pm.

How can you tell people that they are wrong, without knowing yourself. Chances are that the factory format does exactly the same thing as they described. Why don't you try it and if it does something different let us know.
I think there is a difference between the two, can factory format reinstall firmware?
Well i tried the factory format, and it did start out differently than the facory data reset did, and it seemed to be faster, but in the end my phone looks exactly as it did with a factory data reset, so i dont know what its doing differently

oh really? you did the factory format? interesting, your phone is fine?
Yeah my phone is fine, everything works... i mean as well as you can expect, still having same issues as before but it wipes everything including the sd card so you might want to backup any nandroid or titanium backups to your computer because it will erase everything from the phone and the sd card, and put it back to how you got the phone.

So it appears this Factory Format is a TRUE hard reset, compared to the soft data reset. I have a question, does it erase avatar? Does it put avatar back on? What about all the other "stock" programs... does it put them back on?
thank you
Wanna try factory format, I'm scared.
Avatar is stored on the 2GB SD card. Simply remove the card before doing a factory format and you're safe.
Anyone tried the factory format?

Just did a factory format and it deletes everything on the internal phone memory except the stock bloatware programs. It didn't touch my SD card as Avatar is still there. Seems to be a true hard reset.
I did the format and my 3G was gone. Everything else worked and it seemed the same as the factory reset. No problems with Avatar,etc. Any files I had previously altered did not revert back to factory. I could not figure out the 3G issue, though. All of my settings seemed correct but I had no data connection (no 3G, Edge, ...) Wifi worked luckily and I was able to do a nandroid restore.

Thanks for this thread, good information to have.
I'm new to android, coming from BB. I've had my phone for a month now and have rooted, gps fixed, flashed vibrant 4, tried the lag fix, flashed gps fix, flashed back to stock, un-rooted, rooted again, flashed stock.... un-rooted....
In the end I wondered if I was getting in over my head here (I was) and maybe I needed to just enjoy my phone for what it is and stop worrying about all of this experimental stuff. I'm no developer.
So I just flashed back to stock using the nandroid backup linked on this forum, un-rooted and did a soft reset.
I noticed it doesn;t truly wipe the phone though, so now, any time I get any type of glitch I constantly worry that maybe there's some sort of residual settings hanging around... my GPS flakes out and hangs, or shows my location as "accurate within 2 meters" yet map location shows me over 3 blocks away? I start worrying, is this residual effects from flashing the gps fix?
I really don't know, and I was wondering if there was a way to truly hard reset, wipe everything and go back to exactly the way the phone was when I took it out of the box so I can stop worrying that I've jacked my phone up.
It looks like this is the way and I may give it a go once I hear more success stories (worried about the poster above missing data connections).
I'm content to wait for an OTA update, or something really solid like CM6, till then stock with launcher pro is more than enough customization for me.
OK, thanks again to the OP and all subsequent posters, sorry for the long response, taking a break from some work here.
peace,
smutek

I can confirm my 3G came back and the phone looks EXACTLY like it did when I took it out of the box. Surprisingly, it's still rooted, at least it still has the app. Will update as I progress.
EDIT: No problems at all. Got Voodoo running just fine after my fiasco with OCLF. Market stored all the apps I downloaded so it's just a matter of time now. XD

Nexus 4 Won''t pass Google Screen

My N4 doesn't seem to pass the Google Screen. I flashed a new rom because for some reason I stopped receiving messages but could make phone calls. I was on PAC now I tried to flash Revolt 4.4 but now it will not pass the Google Screen. Also, I am on twrp if that helps. I have used normal wipe. then advanced wiping the system,cache,data. Anyone know how to fix this?
-Thanks !

When you say normal wipe, do you mean wipe data/factory reset? If you haven't tried that, try it then flash a new ROM and then gapps. If your problem still persists then you would probably have to revert to stock ROM (factory image)
You may have gotten a bad download of the ROM, or some other problem with the zip. If you still have the zip of your last ROM (always a good idea until you know the new one boots), then try flashing it. If not, as suggested above, revert to stock and start over.

With factory image will my phone be completly erased?
And I mean with when you go to twrp recvoery the normal wipe. Not Factory Reset the standard wipe data and cache.
Fixed it.
Kind of bummed out right now. It seems TWRP recovery was bugged somehow. It didn't let me wipe anything at all. even when it said it did which is odd. I had to perform a factory reset. I'm glad about the phone now booting up. Just a little bummed out all those pics I took on the 4th of July are gone.

Galaxy S4 stops working

Hey guys, i've got a Galaxy s4 running 4.4.2 android version and all of a sudden my device started freezing and stopped working, I don't even know how to describe the problem, i haven't installed new apps or downloaded anything since a month and this problem just started yesterday.
Basically, my phone just stops working all of a sudden, the "X app isn't responding. Do you want to close it?" with whatever app I have on the moment, and after that, the screen just freezes, I can lock my phone and unlock it, but nothing happens, just the same screen frozen, and I have to reset my phone, but the problem is that I have that problem happen to me like 5 minutes after I restart my phone, so basically, my phone is unusable because of this problem, and I don't know what to do to fix this. Any suggestion guys?
I would definitely try and back up any data you need from the phone. Then, I would perform a factory reset from recovery to see it that solves the issue.

I would if I could, but actually I don't think I have enough time to backup all my data before the device freezes, but in the end, if there is no other possible solution, I will just factory reset it even without backup
Thanks, though.

Try pressing the menu button when powering up your phone. that way you will get into safe mode. Maybe then you can make backups.
or
You can flash a custom recovery. Like TWRP and then boot into the recovery. There you have Aroma filemanager and then you can transfer the files to an external sd card.

Great! thanks man, I'll definitley try those options :good: .

Unfortunately the process com.android.phone has stopped

I factory reset it and it stay pops up constantly!
Does anyone have a solution to this problem?!? Im willing to try anything. Ive tried all the ones on youtube with the "solution" but it does not work.
I am also running stock too
I also have this problem. Phone is stock, no mods
Is there a way to restore the phone without the built in factory reset?
I think the recovery files built into the phone may be corrupt...
Tried a factory reset and it didn't work

Hey there! I fixed this problem by actually rooting my phone! It went away right when I rooted it. It seems that it cleared the cache.
