[Q] phone doesn't start after deleting two files from system partition - General Questions and Answers

Hi,
I have an MTK6582 quad core phone.
In another forum, I have taken an advice from a poster, which later proved to be the worst thing I could do..
I have deleted two files from \system\etc folder, namely:
agold_cheat_evaluating_software.xml and
changeram.xml
Due to these two files fake system info was reported (there was another advice to edit these files, but I was too lazy, and the poster told that he had been deleted them, and then the system could boot thereafter with the correct system info. I believed it..)
Anyway, I have deleted them, and since then I cannot start my phone, it stops at welcome screen.
I could log into Android recovery mode, I have made a factory reset, but the problem still persists, and I'm going mad. How could I be so idiot...
Does anyone have any idea how to start my phone? "Fortunately" I have these two files on my computer, I saved them before deletion. Maybe it helps..
Thank you in advance.
BTW it's an M-pai 809t

reinstall the stock ROM of your phone!!

Htc pro replacement

Fisrt of all thank all of you guys for the information I have found here it's been very helpful.
Second, after finding and utilizing information found here to modify my HTC PRO I was forced by a keyboard failure to get a replacement. I tried everything I could figure out to transfer my set-up from the old phone to the new with no success. I was hoping to not have to go through the whole process of finding and installing all the different features and programs I had installed. I was hoping to simply overwrite the new phone with the old. Is there a means to do this? If there is..... could someone explain the process step by step as I am a complete nimrod when it comes to all of this?
Note: when I try to pull up the old phone while connected to my laptop it shows up as a removable drive and is no longer identified as "HTC PRO" and the abbility to drill down into the file system is limited. The new phone appears as it should. I have tried to copy the contents of the old phone to a folder then plug in the new phone and overwrite the file system but there are several files that I get a "file cannot be overwritten" errors.
Any suggestions?
Thanks again guys.

Do you have any backup utility like SPB backup? Some of them (I think Sprite backup) have the ability to backup programs you've installed as well, and that kind of thing is likely to be your best bet. Replacing files manually is unlikely to bring you success though.
EDIT: There's some discussion here that might be of interest.

Hard reset =/= restoring all the system files?

I am using Touch HD (BlackStone), I installed one of the hot fix from HTC and it seems causing my phone lock up with the ICR program. I did hard reset and reinstall the ICR and it still crashing all the time. I spended 2 days playing around with countless hard reset and the problem was still there. Finally I flashed my ROM and the problem seem gone now. Seems like the hot fix replaced some of the system files and the hard reset didn't restored them.
I just wondering what exactly hard reset does? Does it just delete the extra files and settings installed by users without restoring all the system files?
a hard reset restore all files of your phone (delete all contacts, messages, settings, programs....) to original parameters.
It's like a "fomat c:" for a computer !
So when I flash the ROM image into the phone, it will put it in a protected area in the flash ROM and hard reset will copy all the files from there to another portion of the flash ROM and execute from there?
when you flash a rom, it erase (or replace, it's the same) the 'older' rom !
a hard reset just delete all files ! if you hard reset your phone, it will be like you buy it, when you power on your phone at the first time !
there is no multi-partitions, one and only one OS can be flash, install and run at the same time !
I hope it's clear, and I answer your question, because my english is very bad....
Hey, if you try format c: ,you get rid of ALL datas on your disk, including OS !! So, it´s not like hard-reset Hard-reseting deletes all user-made data, but it doesn´t do anything with ROM/firmware files, so if you changed them, you can get them back only by reinstalling OS ;-)

Ah that explain why hard reset didn't fix my problems but re-flash the same ROM into phone did.
So there is a list of files in ROM to tell the hard reset program which are needed to keep?
thanks
sorry, it's to hard for me to explain what I think in english

[Q] accidentally deleted files

sorry for my question but wanted to know if anyone can help, 7 days ago bought a acer stream, I made the root and then exploring delete files by mistake apk system, of course, many things do not work now. If anyone can help they would appreciate a lot. Thanks.
You're pretty much out of luck. If you deleted the files 7 days ago, they are likely un-recoverable. If they are on the sd card, and less than a day or so, you have a chance to recover them using GetDataBack.
Your best bet is to do a factory reset to get all the files back.

remove them from the system and are apk files, there is no method to revive my acer?, it means that I throw it, only serves, I can not load a new rom?

Factory reset the phone. If you cant do it via settings, try recovery menu.

I tried to start from the menu, I did restart buttons and no screen goes black and does not reset to factory settings with some other idea?

Recovering data from opo after deleting /storage folder and factory reset

Hi,
tl;dr:
Is there a theoretic way to recover data from the phone after:
1. deleting /storage folder
2. and then rooting (which means factory reset?)
If there is a theoretic way to recover it from the bits, is there a way to take a snapshot of the current state of the bit, so I can (in theory) recover the media in the future?
Long version:
First of all I know I'm very stupid..
Yesterday I've deleted my /storage folder since in first glance it looked empty.
Then I figured out what did I do, so I tried to recover the information.
I've searched the web for an application that does that and I found one that required rooting the phone, so I rooted the phone which means I made factory reset.
Then I tried to recover but it didn't manage to recover the photos and videos.. (it did recover whatsapp photos and some other things but not from the dcim folder).
I tried then several different applications that may not ask for rooting the phone so maybe I made a mistake by doing that (not sure that they wouldn't request for rooting either) but no success with that...
I'm willing to pay money to save that data but do you think it's not recoverable anymore?
I also called the 3 biggest recovery companies in my country, 2 of them told me that they don't think it's possible and one agreed to take it to their labs for a small price and then give me an offer.
If there is a theoretic way to recover it from the bits, is there a way to take a snapshot of the current state of the bit, so I can (in theory) recover the media in the future?
I'm very desperate and would be very thankful for your help

After few weeks of working on that, I didn't make it to recover any of my photos/videos/whatsapp chat history (the things that were most important to me)
I tried several stuff, apperently all of the recovery programs that using the adb to directly connect to the phone through the PC doesn't work well enough, as well as the programs that works from the device...
I tried this article:
http://www.dflund.se/~jokke/androidfilerecovery/
but it didn't work for some reason...
Then I tried that one :
http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705
I used a centos VM to get a image of the device partiotns the way they suggested (I couldn't make the busybox work).
I mapped that file as hard disk
I tried to use 'Recuva' it seems like it managed to restore files but something apperantly went wrong and the files wasn't helpful...
I tried to use 'easeus data recovery' it worked better, it found around 20k files.. There were alot of directories and I didn't look up at it so much but it recoverd alot of photos which I think were from the whatsapp media.
Incase someone who made the same mistake by deleting the 'storage' folder, get to this post, I recommend to turn off the phone immidietly and find a way to do that without rooting the device.. (although it might be impossible since as far as I know all of the methods I used were depends on a rooted device, but I didn't look up on this since the first thing I done is to root my device - which might be the mistake)...

Allview x2 xtreme memories fixed

Hello all. I am new to the forum and I do not speak English. Helping a google translator.
I have a phone Allview x2 Xtreme and a small problem.
I root my phone out of your forum and I fell android system, so I downloaded the go with your forum and installed. everything went without any problems with one exception. My problem is the inability to save any files to the phone memory. Downloading various applications from Google Play but do not sign up and grind endlessly. Factory settings restored more than once and not washed your any positive results. It seems to me that after installing rom should create folders, unfortunately, nothing. Computer and telephone see partition, but you can not have any utorzyć folders. Please help and sorry for my language.
Something else I noticed. On the phone memory is formed TWRP folder and no other can not be next to him to create. But in the middle of TWRP you can create other folders may help. Or YWRP adapted at each other partition memory and therefore does not see the android. Please help phone admittedly under warranty but with us is how to give the equipment to the site takes a long time to repair.
I'm having the same issue... currently looking for a fix. Seems that TWRP is incorrectly formatting the device.
OK, I had to utilize the Gionee scatter file and stock ROM in order to get the phone partitioned correctly,
I then took the BLU Scatter file and Stock ROM , boot, and recovery and flashed it afterward. Then did a factory reset. Took updates then rooted, again. You are left with the Gionee splash screen... But that's an easy fix.
Appears that the versions of TWRP posted DO NOT partition the phone correctly and writes a TWRP partition that screws everything up.
I will post links or you can find them yourself in the meantime. They are all on xda mainly on the thread about rooting... Odd thing is. Phone seems to run better than before... I would have left the Gionee ROM up and running if it wasn't 4G only... I'll post links later.
