[Q] Factory reset - Android Q&A, Help & Troubleshooting

Hello everyone, i have a problem with soft & hard reset of my phone. If my thread is not on the right place, move it then, i apologize.
I am going to give you as much as information i have. My phone is BLU Life One L120 which is having a duplicate Micromax Canvas 4 A210 which is having the same chipset as i read into my thread for my BLU. Basically what i want to do now is just to soft or hard reset my phone... it sound easy i know but i wouldn't be asking if i haven't got an issue.
First of all i am using stock version 4.2.1 and kernal 3.4.5
I believe that i am having my drivers which i found in my official BLU Life One thread - http://d-h.st/U8e , also i tried with All MTK USB drivers 2014 http://androidurdu.net/mediatek-adb-usb-vcom-driver-pack-mt65xx-support/
However i am able to transfer files between my pc & phone but when i try to root the device (i tried with Kingo root/ One click root) it isn't recognizing my device or is unplugged, which is not true. I remember that once ago i installed TWRP recovery but i can't access from there no longer and i don't know the reason of that, otherwise i would reset it from there. Eventually recently i uninstalled superSU app and now i don't have root access anymore, which grow as a problem also. I checked it with RootChecker app. Also when i was doing both the soft and hard reset i removed the both SIMs & SD card just to be sure that i am doing it right.
When i use the soft reset it's giving me the option to run it but when it restarts it's all the same, nothing changes. It's the same with hard reset when i try to enter into Recovery mode.
Q: Why do i want to soft & hard reset it ?
A:
The first reason is that not a long ago my wi-fi signal got weaker despite that i'm next to my router and it wasn't like that when i bought it firstly and i want to use it instead of paying for it. I read a lot of stuff, but i can't find anything exactly the same.. which is why that i believe that if i reset it, it may went back normally.
The second reason is that i just want to change my factory rom with a custom one , because the phone is having a great performance
I hope that i gave a lot of information, thanks in advance :good:

[Q] Random rebooting during calls

I'm having a problem with my Vibrant. I've looked through the threads & can't find exactly what I'm looking for. I bought my phone second-hand so I don't know how it was rooted, or what was done to it before I got it. It was 'clean' when I got it, so there were no added apps or files or anything. I started having problems with storage space. I would get a warning, but when checking there was plenty of space. I did a factory reset, & I got a force close, so I did another factory reset & it was fine. It's running Open Kang ICS. It was on it when I got it, & was still there after factory reset. I used Titanium to back-up & restore my apps. (I've backed up with GO backup too, but didn't use it to restore). Since restoring I've been having issues with my phone rebooting randomly. It's happened in the middle of a phone call 4 times now (so far). I also have an issue with not being able to turn my screen on. I try to unlock the screen & nothing happens (but it's still on) & I have to take the battery out & put it back in & turn it back on. My brother suggests a new ROM, but I have no idea how to do any of this. I didn't flash this one, & I didn't root it. My brother didn't root it either (he rooted my previous phone) so he doesn't know how it was done. Any help would be appreciated (including step-by-step in language I can understand LoL). I have tried installing ClockworkMod Recovery but for some reason I can't get it to work on my phone.
The vibrant bible thread has a tutorials section that links to some pretty good tutorial.

and the Vibrant AIO toolbox is a great program to help with rooting and flashing

Here are some codes you can use just like you are dialing a phone number. You can even perform a factory reset. http://androidforums.com/vibrant-ti...ck-built-day-time-firmware-gps-test-more.html
Use with caution, I personally have never used these codes.

no keyboard on lock screen

Ok, so I have a serious problem... My phone is locked and when I touch the text bar to enter the password, no keyboard comes up. Important information:
- I just upgraded to jelly bean (the official one that came out today)
- as far as I can tell, everything is working fine, i just can't unlock it
- when I touch the text bar, it makes a noise, but no keyboard comes up
- was working fine immediately after the upgrade
- I got done fixing some settings and locked the screen
- this may have something to do with changing the default keyboard to Google Keyboard (it was acting a little funny immidiately after, like it was crashing)
- I have Android Lost installed, the unlock function isn't working, but others do work
- phone is encrypted
Unless someone has some ideas for me within the next couple hours, I'm going to wipe the phone. Obviously, I would prefer to not do that.
==========================
EDIT:
I've managed to use Android Lost to make some backups of some stuff, but I'm still trying to figure out how to unlock the screen. I've found that I'm able to install apps remotely from google play if that gives gives anyone some ideas.
=============================
EDIT2:
I had another idea. If this is a problem with the keyboard, is there a way for me to change it remotely? Can I install another one via the store?
Alright... I gave up on trying to get passed the lock screen and tried doing a factory reset. I was afraid of the super brick issue, so instead of doing a wipe in recovery mode, I used Kies to reflash it. However, that did nothing. The phone started back up and acted like nothing happened. It asked me for the same password, then got to the lock screen and had the same keyboard issue.
I've tried various roms, but nothing seems to wipe the encrypted information properly. At some point, I got it to forget the password, but it still thinks that one exists. I even rooted it and tried shostock3, but when it boots, it asks for a password. The old password doesn't work, so I can't get passed it. I tried entering the "wrong" password many times and it said it would wipe the phone, but it just restarted to the SAMSUNG boot screen and just sat there. I pulled the battery after half an hour...
I should note that stock gingerbread seems to work fine...
Does anyone have any ideas on how to wipe the encrypted data?
If you can push apps to it, try pushing an app like no lock or something.
Short answer: No.
It is probable that encryption information is stored in the efs (encrypted file system) folder. That's where the imei and other critical stuff is stored. I don't believe anyone who posts here in the I777 forum really has a grasp on how phone encryption works though. I've only seen one other person post here who had an issue with an encrypted phone, and he was unable to solve his problem as far as I know.
If you have a proper backup of the efs partition from before the phone was encrypted, it is possible that you could solve the problem by restoring that partition. But I'm not even sure you could write to that section of the phone memory with adb with the phone in it's current state. Edit: if you can boot into stock gingerbread normally, then you can restore an efs backup, if you have one.
I'm guessing you could send it to Samsung and they could fix it for you probably.
I finally got it working. I'm not sure what combination of things did it, but I had to restore it to stock jelly bean (via kies) to get it to wipe the encryption. I guess the stock rom knows how to properly wipe it when you keep entering the wrong password. After I got it all cleaned up, I put shostock3 back on. When the battery charges back up, I'm going to try encrypting it again (in shostock).
However, now I found another issue (may or may not be a real problem). I wanted to check if the phone was still unlocked, so I dialed *#SIMLOCK# and it says "Connection problem or invalid MMI code."
Tada!
Creepy, my good friend, would be referring to me and as you know SCIU I didn't ever get it to unlock the phone. Oddly enough a stock ICS rom (my mom now has my phone right up the road so I may try this to see if it will work and then go back to ShoStock3) works fine. I have nothing hidden from the phone storage, everything shows up, it is actually unlocked and rooted though not a custom bios err firmware/ROM because when that is put on there the encryption issues come back and the password is asked for. If the correct password is entered (and my KEYBOARD comes up but I didn't change it from the Android/Samsung one) it proceeds to enter whatever it is supposed to (my guess is the POST area like on a computer when it is entering Windows/Linux, etc.) but the screen stays black (ShoStock logo doesn't even appear if I remember correctly or it does show then goes to black loading screen with the Samsung logo and that is it, perm stuck). However I did try flashing back to Gingerbread ROMs and ICS ROMs though not through official KIES.
SCIU I may have to give this a try if my mom don't mind it and see if that helps fix the problem. Thanks for starting this thread. I am sorry I didn't respond to the PM you sent me (my LGOG, Triple OG, OG, TRIPLE OG, Optimus G AT&T Phone has screen cracked twice and is unresponsive on two different phones so I sent that in to warranty repair [rapid heating and cooling issues]) and haven't been on XDA for a week. If there is anything else you need to ask or bounce ideas off of me then I am all for it.
As far as encryption goes, the process works the same as any other encryption algorithms used (MD5/HASH/SHA-!, etc.) using a basic replica of most file systems although mobile storage tends to work a tad differently. Unfortunately, the freezer trick, brute force, nor any other cracking methods I was able to try at home worked to get it to open up. I tried getting into the EFS area of the phone but never could get to the directory or have it display.
Again thanks SCIU and as I stated I may give this a try if my mom don't care.

You can get the full stock jelly bean Odin flashable tar in the Download Repository. See link in my signature. According to sciguy125, flashing stock jb and then inputting repeatedly the wrong password will clear it. I'm not sure how many times it takes, 5 or 10 I think. I've never worked with an encrypted phone. I'm just repeating what I have read others say. I've seen the above posted by at least one other person. You should be able to flash the stock firmware using Odin. The one you want is I777UCMD8

Friend, this is the forum for the S2 (Samsung), so you won't find anything about Huawei devices here - best to ask your question in the forum for your device.
That being said if you are rooted and have a custom recovery, simply power the device off and boot into recovery and perform a factory reset from there. If that doesn't work do a full wipe (this means wiping /system), then re-flash the ROM/gapps.
me too!!! do you have some tips for me?? i almost fainted when i knew that the keyboard isnt working.... i do have a lot of important files in my phone.
Easy, you fools! JUST KIDDING lol Connect an external keyboard. Restart the phone with the keyboard plugged in and you'll have one chance to input the pass every time you restart. Good luck, bosses!

Solution that worked for me
Hello all,
I usually don't post things around, but something told me to do this, since I don't see any threads talking about this solution.
My solution was the following:
Went to google play store on my computer via chrome. Logged in to the user attached to my play store and re-installed all keyboard apps I have.
That worked beautifully and hope this helps other people!!

[Q] Bootloader unlocking and clean rom flash.

Hello,
I have a Asus zenfone 6 however my problem also occurs on the zenfone 5 phones.
The poblem is as follows,
After updating from stock to latest android (v1,18 at the time) the phones battery display became incorrect making the Phone unreliable at bestand nothing seems to help fixing the problem.
I have tried a million calibratnig apps with zero success as suspect the phones software doesnt actualy understand that it has a 3230 mah battery.
I have found and compared files with a working zenfone6 where the file displays 2070mah for me and 3230 for the working Phone.
I then tried to manualy change this file had no acces even with root but every reboot or unplug it just resets the file anyway as it gets its data elsewhere.
I have tried a factory reset but not everything was actualy reset it just deleted my data but roo and all othr crap that the update screwed up was still there.
I tried ADB sideload but that didnt work and udupdates as ota so will not factory reset and remove root anyway.
I contaced asus but they are as clueless as a goats rear and just say a future update will adress it...Which we al know isnt going
to happen as this has bin a issue for some users for over half a year and they didnt fix it.
So as a final attempt to fix this Phone im planning on unlocking the botloader which i really didnt want to do as im new to all that and just want a rooted stock rom...
So to my question.
If i unlock the bootloader i know the Phone will be wiped. Will i just be able to flash any version of the stock rom via ADB or is there other things i need to do to either the Phone or the rom?
I cant go screw up my Phone without knowing how to fix and flash it again directly.
And do apps like the one asus provide usualy also allow relocking of he bootloader again after flashing the rom as i dont want to leave it open if there is no need to?
Any other ideas are welcome aswell but i have bin trying to solve this for over a month.
Heres a screenshot of the error i get when i try to reflash current rom with ADB.
http://oi60.tinypic.com/2eefzuv.jpg
But as long as that doest a full clean rom install its not helping me anyway.
i really hope someone has a easy and quick way to do a fresh install that will really make the Phone like it was just out
of the box software wise. no root no changes or anything as factory reset is not doing that for me.
Thanks in advance.

Ulefone Vienna No command bootloop after failed update

Hi, i have little (or maybe big) problem with my Vienna. Yesterday phone asked for Wireless Update and i allowed it. So Update started to install, almost finished it. But at the end it just gave error and rebooted and then there is just Ulefone logo after what it gives No command error and just continues to bootloop. I tried to wipe cache through recovery and even factory reset. It just wipes my data and thats it. No factory reset. I cant restore backup either. It just says no SD card. I'm kinda new Android user, so i dont know what to do next. Kinda frustrated about that update. It basically bricked my phone. Anyways phone is running stock 5.1 version. Thanks who can help me with this :fingers-crossed:

This had happened to me too. Try to update it again trough sd card by getting into recovery mode (youll find vids how to get into recovery mode). The 6.0 version isnt very good (it can hanlde more apps though, I have ~500 apps). BUT, MOST IMPORTANTLY; after the upgrade factory restet the phone (more than once would, I think, better). I didnt do that and I think I should, since that may enable me now to get again in recovery mode (yeah, now buttons dont work, Ive to do this via PC), my phone maybe would be more compatible with PCs and I may was able to root it. By the way, there is another xda forum about ulefone vienna where you could get more answers and Im not a professional. I hope I helped (with some months delay).

Factory Reset won't work: Meizu M5 Note, After trying to UNROOT using SuperSU

Oh guys, I badly need your experties. Just as I have in the title, I have a rooted Meizu M5 Note. I rooted the phone believing that I can do much more if it is rooted. But in 6 months of trying to understand what I can do with this said rooted phone, I realized now that there are not much to do with it... Probably because of the brand, so I decided to unroot
The rooting process was from here: giving me error so if requested, i'll give the link.
I have an Android build 7.0.0.0
So here is my issue:
In the same site, I found that I can unroot.. yes, UNROOT the rooted model of phone using superSU by going to its Settings and clicking unroot (or Unroot all something..). It took a bit while, so I decided to restart the device. Yes, while SuperSU was trying to unroot my phone.
Upon restart, it now could not boot.
I allowed 30 minutes, the screen only shows Flyme logo with a spinning circle. So from here, I made up my mind to perform the factory reset/restore:
Turned off Phone > Press and hold Power key + Volume Up... until I reach the screen with options to:
-Update system.
-Wipe data.
I selected Wipe data, for it will reset the system settings. It will now show the
"Wiping data.
Please dont turn off the phone, or it may fail to boot"
It will only last for 2 seconds - and will then again reboot and stop in Flyme logo with a never ending spin below.
_________________
It was already the factory reset, which I thought should help, but it wont work.
_________________
Things I tried:
- Used ADB to flash an offcial update rom from the flymeos.com, but the ADB Flashtool would not read the device because the USB Debugging is turned OFF.
- Googling any possible solutions, but cannot find any - nor any known programs that will allow me to read the not booting phone.
- Fast boot or safe mode, which only wont proceed.
- The Recovery Menu (the un-clickable one) must be locked by the manufacturer.
Can anyone please tell me:
- Is there anyway I can access the phone's drive so I can put the Update zip folder, which will help me to use the 1st recovery option "Update system"??
- Do you have any software that can help me enable the USB debugging when the phone wont boot at all??
Thanks guys..
All the help I can get will be best appreciated.
I tried posting this to forum.FlymeOS, but no one seems to have any interest on helping.
It is now you, that i think can help.
This is my Only phone, and cant afford to lose it...
Same issue with my Meizu M5 Note. I tried a tutorial on how to unlock it's bootloader. But after going through the first step, the SP Flash tool showed some error on how it does not turn on our go recover mode or anything... In really sad
