So, I bought a cheap non-branded chinese android smartphone. The handset was full of useless pre-installed apps and I just cleaned them out. I rooted the phone with the VRoot tool and it looked like everything goes well, untill I made a factory reset. I installed a new launcher, of course to the /system/app/ folder and it worked with it. The phone has some kind of startup setup (like the iPhones) which comes up after the reset, before the launcher could start. In this procedure, the last step is to tap on an android logo to begin using the phone. So for now, even if I tap it for a houndred of times, the thing won't start, it sticks in this setting window. I pretty much think, this happens because of the new launcher, because the app is probably looking for the old one. Now I am in the deep sh***t.
The followings are known:
- I can't use ADB to repair it, because the factory reset automatically unchecks the USB debugging.
- No firmware or recovery backup available to reflash the handset. The phone has a qualcomm MSM7225 CPU.
- I have the factory apps.
- The phone has factory recovery, so I can't install custom backup.
- I can enter in fastboot mode.
I think, this is all I know. Anyone has some advice to repair it?
Thanks is advance.

I recently purchased an Optimus T and rooted it with z4root and then installed Titanium Backup to delete some of the preinstalled apps, like the Pacman Demo.
As I was removing each app, (~5 at this point) the Home button suddenly stopped working, followed by total phone death. Even after factory reset, when I was trying to access the phone, eventually I was shown a "... setup.exe stopped responding..." (or something like that) message and my phone just stayed stuck on the booting screen (android) every time I restart (w/o entering factory reset).
Does anyone have any ideas, or know which apps can prevent the phone from booting properly? A list of safe apps to delete would be helpful too. I thought I was pretty cautious with removing only non essential apps, but it seem bricked. Thanks again!

About list off apps, I have to agree. Even it there is litle problem with dependencies, some minimum describe of these issue will be great!!
So, about your problem - I think, that you will have to download original ROM and do flashing with KDZ_FW_UPdater. (search on xda for more information).
But definitely, if it's possible I would try to install custom recovery throw adb shell (android SDK tools) and do backup of system for possibility to recovery or saving at least few data, and after try wipe and install one of custom ROM.
This happened to me after I tried deleting preinstalled apps on my Optimus One... Sent it in for repairs since it just stopped working. The tech guy said he did a "software update" and everything is good as new (except for the LGMITS error once in a while)
They didn't even bother trying to fix mine. They just told me to send it in and gave me a replacement.
So I finally figured out what I did wrong - basically when I was doing the deleting, I accidentally deleted the LG Home app, which effectively deactivated my (duh) home button and effectively stopped everything from functioning properly. For some reason I thought it was just a simple link from my phone directly to the LG website, as would happen with new PCs very often. Well... won't be doing THAT again.
However, my web2go button isn't working. I have to force quit every time I try to click on it. Can I just get rid of it or will it just give me more trouble later on?
At least you knew what went wrong with yours... I was just erasing CarHome and Layar and the LG App Adviser among other things i wont be using like Twitter and Latitude.
And they even gave you a new one x__x I had to wait 5 days before everything was good as new. After the first fix, USB debugging and mass storage stopped working so I sent it in for another "software update"...
Hi,
I have an lg c800 -- mytouch q by lg
I rooted it yesterday and removed all the bloat. I also installed several root only apps to optimize the phone.
It ran smoother than even right out of the box.
So, I figured it be a good idea to backup the rom, and maybe later try cyanogenmod... So I installed Rom Manager by clockworkmod
It said i needed to install clockwork recovery rom. I went in there but it said my device was unsupported (only like 12 were) so I backed out,
and stupidly hit TWRP listed under "Recovery Already Installed". (thinking that meant what options I had to SETUP a recovery/backup)
I hit backup rom. almost instantly the phone restarted. After the bios, but before android it went to a screen with a box, and an arrow pointing from the inside of the box to the little android man. Then went to the regular android boot screen.
It does this every reboot now. The SuperSU is still there, whenever Rom Manager (which I have to reinstall each reboot) asks for root access I get that dialog box, so it hasn't actually hard reset the phone I don't think. But all the user data, contacts, apps, wifi passwords, google id "(to access Play) get wiped out.
I understand what I did wrong. I think I understand what its doing (booting to the factory rom as it was, and I can't set it to stop doing it each reboot)
What I need help with is getting back, if possible, to what I had previously, among other things, I had a bunch of tasker profiles and notes that will be time consuming to replace.
Thank you for your help.
EDIT: SuperSU is now listed among the factory installed apps. This is unchanged each reboot.
Question: If I unroot the phone what that invalidate Rom Managers ability to run before android boots?
the phone is a Homtom Zoji z6 which so far seems to not have many root'ing options available and I have been trying to root it but failed and quit trying so I reinstalled the original rom, which is not a backup or anything, just a rom from the homtom website which should work fine
the main problems are:
- unrooted phone with no custom bootloader installed which means no cache or dalvik reset
- phone just got a fresh installed rom and no usb debugging or oem unlocked, therefore stuck on the launguage select menu of android's first time boot
- unresponsive touchscreen, cannot use touchscreen at all (not sure about home, return and option buttons as I don't think that they do anything at the language select screen)
- non removable battery, removable by unscrewing the phone and removing back cover though at least 3 sensors can be seen inside which may be the most likely reason for the unresponsive touchscreen
- otg to usb female adapter unavailable (been trying to ask friends and find a place to buy one but so far no luck besides buying online which would take more time that I would like to spend on this)
- chinese factory menu (fml), also! ...got into this menu a few times but it doesn't seem to be working anymore, no idea why
- I want my phone back, dammit!
been trying to find some kind of software for pc that could redirect a usb mouse to android without root but apparently there is none or I'm looking in the wrong places
already tried to use the touchscreen calibration from the chinese factory menu but don't think it's detecting at all, factory reset doesn't work either
I'm all ears to suggestions
I have a Galaxy S III GT-I9300 I bought in 2014. After three years, I downloaded a custom ROM from xda-developers (android 4.3 is all I remember about it) and installed it successfully. It worked alright until one day when I wanted to sell the phone and a customer wanted to buy it on short notice, and I rushed to delete my files from the phone, but I destroyed the Android... I connected it to my laptop and shift-deleted some system files.... since then, the phone is delaying when trying to unlock (if i lock it now and try to unlock it a few times, it opens harder and harder), when I'm using apps it continously shows that some .com processess stopped working, and if I try to turn on the bluetooth, the phone instantly freezes and restarts itself.
I tried reinstalling two original ROMs, (version 4.1.2) successfully, but the data on the phone&the system problems remain the same.
I'd like to know how can I make a hard reset, meaning in deleting all the files&settings as it was brand new, just to clear everything, like clearing CMOS. I also think the recovery mode is damaged and I'd like to fix it somehow (if this is possible). The installation process I did for installing the custom ROM from XDA-devs was long and complicated, I had to do a lot of things... and I just want to get the phone fixed and restore to default (or even to fix bugs on this android version) its android, kernel & everything could be ,,reflashed''.
I'm willing to pay if someone helps me fix the problems and it really works. Thank you!
