[Guide] How to flash back to Stock Rom - chacha. Please Sticky This !

Alot of the guides floating around showing how to flash back to stock rom is incomplete ( missing a few steps ) and will result in boot loop most of the time. the correct procedure is :
Part 1 : Setting up Fastboot.
1. Make sure you have java installed, if not get it from here : http://java.com/ and install it.
2. Download the Android SDK manager from here : http://developer.android.com/sdk/index.html ( get the exe download )
3. Install SDK manager, then run the android SDK manager.
4. Once launched it will show you available updates, choose ONLY these two "Android SDK Platform Tools and Android SDK Tools" and update them.
5. After update is complete close the sdk manager and go to the SDK manager platform-tools folder, normal path is : ( C:\Program Files\Android\android-sdk\platform-tools )
6. Copy the following 3 files from this folder : "adb.exe" , "AdbWinApi.dll" and "fastboot.exe"
7. go to your c drive ( c:\ ) and make a new directory called "fastboottools"
8. copy the 3 files above into your fastboottools folder.
9. so now your should have a folder like this : "c:\Fastboottools" with the following 3 files in it "adb.exe" , "AdbWinApi.dll" and "fastboot.exe".

That is it, Fastboot tools is setup. Proceed to next guide.
Part 2 : Flashing guide.
1. download the ROM from here:
ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35. 3033h_7.51.35.19_release_228383_signed.zip
or here ( mirror link ) : ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35.3033h_7.51.35.19_release_228383_signed.zip
2. Extract and copy the system.img AND boot.img to the same directory as your fastboot tools "C:/fastboottools" ( make sure to copy both files )
3. Enter the fastboot mode on your phone by pressing volume down + power button after the device has been turned off.
4. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC
5. Using fastboot tools, open the Command prompt and navigate to "C:\fastboottools" then run this command on cmd: "fastboot flash system system.img"
6. Dont reboot, Using fastboot tools, run this command on cmd: "fastboot flash boot boot.img"
( The two commands in step 5 and 6 are different, make sure to type each one correctly and to do them straight after each other )
7. Reboot phone. let it boot up, you will still get bootloop or error message.
8. Take out the battery.
9. Boot back into bootloader ( Volume down + power ).
10. Now choose recovery.
11. Phone should now reboot itself and bam, all should now work fine.

after trying EVERYTHING else, this is the method that worked for me, i tried to cover every step possible ( alot of the other guides skipped few steps and that is where i got problems ).
hope this helps.
( PLEASE BE AWARE : This will remove recovery and root. if you flash back to stock rom using this method you will have to root your phone again. It will still be unlocked, just recovery and root will be removed. to re add recovery and root check part 3 below. )
Part 3 : Add recovery and root access back after installing stock rom.
1. Download the following 2 files, you will need them :
PH06IMG.zip
su-2.3.6.1-ef-signed.zip
2. Extract PH06img.zip to your "c:\fastboottools" directory. it will add the "recovery.img" file to fastboot.
3. Copy the file su-2.3.6.1-ef-signed.zip to your phones SD card, dont change the name, keep it standard, just put it in the root directory of your SD card.
4. go to the settings on your phone "Settings -> Power -> and Uncheck Fast boot" ( This is important, make sure fastboot is unchecked.
5. Take out your battery, put battery back in and boot into bootloader ( hold down volumedown + power )
6. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC
7. Go to the Fastboottools directory "c:\fastboottools", Hold CTRL+Shift and right click in that Folder and open Command Prompt.
8. type inside command prompt : "fastboot flash recovery recovery.img" and let it finnish, takes less than a minute.
9. reboot your phone, but reboot it back into bootloader ( hold down volumedown + power )
10. Now using volume keys choose "recovery" and press "enter" ( not power button, rather use enter button in recovery else you sometimes get a "hat like" picture on the screen )you should now see the recovery options.
11. find the "install zipd from sd card" option and press enter, then choose su-2.3.6.1-ef-signed.zip and confirm to flash it.
12. once flashed reboot the phone and you will now have recovery and root access back again.

it is recommended you update superuser to newer version and also install busybox.
Now that you have recovery installed you can also flash custom roms again.
I STRONLGY recommend once you reach this step that you make a backup of your rom via the bootloader recovery menu, that way you dont have to go through all this pain again next time.
The End !!!
feel free to post any problems you encounter below.

stuck on bootloop at step 10
I've attempted the recovery and get as far as step 10, but unfortunately
"still suffer the bootloop.
what am I supposed to do in the recovery step to get it working fine!
do i load the update.zip?
please reply if availale... am stuck on bootloop
ty

bootloop ussualy happens when you dont clear your cache properly before flashing.
Make sure to clear ALL cache, and also make sure to follow the steps exactly as they are posted, even if it looks like you can skip a step DON'T. do each step as posted, and clear all cache when you are told to. then you wont get boot loops.

Hi,
I bought HTC chacha locally at a online retailer. Its not tied to any sim/operator. However I am stuck at android version 2.3.3. (firmware version 1.20.720.1). If I try to run the (ota)software update, the phone says no updates available.
I really need to unlock the boot loader. However if I try the htcdev.com, the RUU utility says that the please update to 1.57.XX and then try unlocking the bootloader. I am really stuck here.
My question is can I try the steps mentioned above in this post to get the firmware update, with a locked bootloader?
Any other suggestions to update my firmware to the latest 1.57.XX?
--Thanks in Advance..

htc status restore factory 2.3.3
No, I didn't make a real backup! I thought titanium backup would cover that, it didn't, so I have no backup of the stock stuff.
I have a HTC Status (aka chacha) US ver with att. I unlocked the boot loader by htc's site, worked fine. Then I rooted it with cmw, worked great.
Recently the ota 2.3.5 update (48mb) became available. I downloaded it and tried to install it, it failed with checksum. I know it is the cmw mod. How can I get the stock load 2.3.3 back onto my htc status? The above directions mention the "asia" load. Are the files mentioned generic for all phones with the exception of the cid?
p.s. It would be great if someone out there had the stock 2.3.3 recovery file for the status! That would be easier to load than the sdk stuff.
update : both ruu files listed above show to be corrupt when unzipping.
Update: I installed a newer zip utility than the stock win xp one and it unzipped without any trouble. Moving on to the next step.
Update: all went well, except the "english" option, I chose english singapore. Installed cwm and rooted again. updated to 2.3.5. Thanks for the info above.

thank you!

A new ota update was available (1.57.707.3) but it won't install, it says the current rom seems to be altered and it refuses to install. So I went to htc.com/support and found the status page and downloaded the latest installer for 2.14.502.2 rom image. It fails with "security fail" under ruu in the phones bootloader screen.
The installer on the pc say's I must get the correct rom installer for my phone. I think it might have something to do with the asia chacha system and boot.img 2.3.3 stuff I installed.
Current software is android 2.3.5 and software 1.57.707.2
Is there anyway to get rid of cwm or force the new rom to install over the old?

Thanks man
Tried and made it
Work very fine except I cannot update sofware to newer version... Stuck on 1.54.401.2

I'm having the same issue.

You need the stock rom for the update to work. But frankly, I did not see any improvement. Battery life sucks.
I'm back to CM9

[Q] Cannot flash any recovery or ROM!

Hello.
I have an Alcatel One Touch 908F running on Android 2.2.2 that I successfully rooted. Then I installed a CWM 5.0.2.7 recovery. But then, after flashing a custom ROM Android 2.3, it turns on but does not boot up anymore (Stuck at Alcatel One Touch logo).
So I booted to recovery and tried to flash my stock ROM, but it shows me "E: Cannot mount /sdcard". I got the same error by selecting the option "Mount /sdcard".
Then I booted it up into Fastboot mode and connected it to my PC. I typed the command "fastboot flash recovery ..." but then after sending the recovery successfully and when trying to write it, it shows me "FAILED (remote:flash write failure)". I tried to run the command "fastboot -w" and I got this :
Erase successful, but not automatically formatting.
File system type not supported.
Erase successful, but not automatically formatting.
File system type not supported.
erasing 'userdata'...
OKAY [ 0.599s]
erasing 'cache'...
OKAY [ 0.229s]
finished. total time: 0.834s
I always get the same errors though I slow-formatted the 2GB memory card in my phone to FAT32 multiple times and changed the USB port.
I guess that my phone is soft-bricked and that its internal memory is messed up (I am 80 percent sure).
Can you help me, please ? I looked for the solution for several weeks and couldn't figure it out. I'm now desperate.
Thank you very much.

try this if ur stuck in bootloop, soft bricked or any kind of problem during boot....
Try flashing your phone's stock firmware using flashrool
Step 1:- download flashtool
Step 2:- install flashtool ( if u dont know how to install then check out the right way)
Step 3:- install driversv from driver folder in flashtool
Step 4:- check the last two box
Step 5:- copy your phone/tablet Stock firmware and paste it in firmware folder in flashtool ( u can get ur stock firmware from Google just search there)
Step 6:- open flashtool
Step 7:- connect your phone/tablet in flash mode
Step 8:- now,clicl on flash icon in flashtool selct flash mode
Step 9:- select ur phone/tablet firmware at left corner
Step 10:- check both the boxes at right upper corner
Step 11:- and click flash ( it will take about 20 mins so take a cup of tea)
Now, disconnect ur phone and start..... Now, you have
To root again... Happy rooting
NOTE:- THIS METHOD CAN HELP YOU IN EVERY WAY EITHER YOUR STUCK IN BOOTLOOP OR YOUR PHONE IS SOFT BRICKED ETC.....

PLZZ DONT FORGET TO HIT THANKS BUDDY

Maybe CWM Recovery 5.0.2.8 wil work

Sorry. But it does not detect my firmware. I tried selecting the other mode (fastboot) but it does not seem to work. Plus, I think flashtool is only for Sony Xperia devices while I have an Alcatel. Any other suggestions, please ? Thank you.

Thank you all for my help. I finally managed to get it right.
I changed the SD card and updated my CWM to 6 and it worked!

[ROOTING] Ulefone Be Touch 2 with TWRP recovery

Hi Folks,
Disclosure: No responsibility taken or accepted in any form if the following process failed.
As forum rules prevented me from posting links try to understand how to find referred files.
1. Prepare a PC with Windows 7 installed and the automatic Windows driver update lookup function possibly disabled.
2. Download BETA-SuperSU-v2.49.zip (appr. 4 MB, from chainfire eu and copy it to the phone's SD card or to an external micro SD card.
3. Download the latest stock ROM and flash tool packed together (e.g. 'Be-Touch-2_150702_s7yler.zip') from needrom com . Search for ulefone-be-touch-2.
4. Download TWRP recovery image file from needrom com . Search for be-touch-2-twrp-2-8-7-0.
Extract the rar archive and rename recoverye.img to recovery.img
5. Extract 'Be-Touch-2_150702_s7yler.zip' and replace the recovery.img file in the "Be-Touch-2_150702_s7yler\One Key Flashing(Be Touch 2_150702)\software" folder with the one from the TWRP archive (see point 2).
6. Install the MTK chipset driver (it works on Win7 only at the present time):
- Navigate to the "Be-Touch-2_150702_s7yler\One Key Flashing(Be Touch 2_150702)\Driver Auto Installer" folder.
- Open a Command Window to see what happens on the command line.
- Run Install.bat with real Administrator priviledges (in most cases Run as Administrator may not be enough - refer to UAC).
- Wait until the driver installation is finished. You will see on the screen if the drivers were installed successfully (e.g. "Driver install done").
7. Flashing ROM
Notes:
- Flashing ROM will wipe all your data. If you have not done a backup before you will permanently lose your data!
- The doc file containing pictures included in the zip file can also be followed.
- Do NOT format your phone with the flashing tool, that can result in lost IMEI.
- For anvanced users: the flash_tool.exe in the Smart Phone Flash Tool package can also be used only to flash recovery.img using an enclosed scatter.txt file.
a/ Open the Be-Touch-2_150702_s7yler\One Key Flashing folder and run SP_Facility_DL_Tool.exe
b/ Turn off the phone, take out the battery, press the Scan button in the SP_DownLoad window then connect your phone to the PC via USB.
c/ After the text "N/A+COM(x)" appears on the left hand side of the window disconnect your phone, reinsert the battery, press the Start button and reconnect your phone via the USB cable.
d/ Wait until the flashing utility finishes updating the phone (e.g. the process bar shows 100 % on yellow background and "DL OK" can be read to the left of the process bar).
8. After flashing, enter the TWRP custom recovery: press vol up + power to boot for a few seconds then install BETA-SuperSU-v2.49.zip from your (external) SD card.
9. You are done with rooting.

Again, for advanced users: You can also use fastboot (get it elsewhere) to flash just the TWRP recovery without wiping the rest of the phone: (e.g. "fastboot.exe flash recovery recovery-betouch2.img"), then use it to install supersu. You can also then flash the stock recovery back over it if you wish. Works like a charm.

Yes you are right. The method I described above also updates to the latest(?) Ulefone ROM as of 02-07-2015.
Even you can flash a Carlive recovery (tried and works) based on the downloadable from the "Ulefone Be Touch 2, 5.5 Inch Full HD, Metal Frame, MT6752 64-bit, 3050mAh Battery" thread Post #76. Carlive (originated from CWM) lacks the annoying splash screen which is included in TWRP.

UPDATE: Never mind, I got it. WooHoo
Guys, how do I get to Fastboot mode on my BE Touch 2? I tried power + volume down, yet it takes me to chinese menu I do not understand.

Installing a Recovery on Xperia M2

Hello all,
Before all, yes I have read many thread about installing a Recovery on this Phone (LB & UB).
So, what I have done :
- Unlock the boot loader following the Sony's guide → OK
- Installing fastboot on my debian →OK
- Flashing boot following this guide : http://forum.xda-developers.com/xpe...2303-cwm-based-recovery-6-0-4-6-root-t2884503 → OK
- Now I have a "Cyanogen recovery"
- I want to change this Recovery to TWRP and I have following this topic : http://forum.xda-developers.com/xperia-m2/general/unlocked-bl-root-sony-xperia-m2-android-t3214498
I write this command :
Code:
fastboot flash recovery RECOVERY-TWRP-2.8.7.0-D230X_D240X-UPDATED-THEME.img
Sending 'recovery'
OKAY
writing 'recovery'
OKAY
finished
But nothing happens I'm still stuck in 'cyanogen recovery'
Any idea what i have done wrong ?
Thank you !

Easy: that Cyanogen Recovery (which is an old version, btw) is stored in the boot image as a separate ramdisk, with a script that pops-up an LED to tell you to decide to open it or not. The TWRP recovery however is in a separate /recovery partition, and it can only be triggered via Vol- + Power until the BIG Sony logo pops-up. That's it. You can have both at the same time if you wish so

Hello !
Thx for the reply !
After several try, I never show the TWRP booting. Always stuck on the cynaogen recovery.
I has flashed again the phone with flashboot and the last stock system to reset completly all partitions → OK

Can't do that, because i am stuck with the cyanogen recovery and unable to start a ROM.
I have used the Flastools to restore an Official Stock Rom due to this.
I will change this phone on fews days, so I will retry later when giving the phone to my nephew.
Thank you for the time spend !

This is probably because you didn't do step one first. Step one unlocks the bootloader so you shouldn't receive this error when you try to flash recovery. If you can't do step one because android is out of date then you need to update android first. If you can't update android then welcome to the club, you probably have a cn recovery and need to update to ww. This can be down following these instructions assuming you have a z010d/sd410/8916 https://ainotech.com/how-to-flash-firmware-asus-zenfone-max-zc550kl-root-custom-twrp-recovery/ Follow the instructions for AFT.
However now I'm stuck on the bit everyone else is stuck on. Once TWRP is flashed, how to boot directly to that instead of android first??
EDIT: I figured it out. It's because this build of twrp 3.2 and even 3.1 is broken for this device. Flashing twrp 3.0 works fine but of course that doesn't support many modern custom roms so it doesn't really help.

you should install the downloaded app on the step number 1 in order to get along with the other steps.
