You are the guy who developed the custom ROM for A27 Bolt, right? How did you take the nandroid backup before flashing the new ROM? I have been meaning to ask you this.
If you have taken the backup using CWM recovery, then which process did you follow for flashing the recovery? Is it the one mentioned in this forum for A27 Ninja?

That defeats the purpose of the CWM recovery, as we need to be able to get into recovery when the phone is BRICKED, so I looked around for this kind of problems. I was using the ROM Toolbox Lite for rebooting into recovery. I am currently using the the following through ADB to boot into recovery when the phone is turned off, so it will also work on brick:
Code:
adb reboot recovery
As far as I understand, if I can extract init.rc ouf of boot.img, (init.rc opens with notepad) find “service flash_recovery /system/etc/install-recovery.sh” and comment it (put # before the line and the next lines in this paragraph or the next command), and then save init.rc and rebuild the boot image then flash the boot.img back, then we will be able to get CWM by pressing the power + volume up button.
The problem I am facing with this are 2:
There is a separate init.rc in my "System" directory, and it contains the line. Should I change this one or extract the init.rc out of the boot.img?
How to extract init.rc out of boot.img and after editing rebuild the boot.img?

having same problem with mmx a27 so u guys find the solution ? plz help .... (only vibration problem after flashing dreambolt rom )
If Micromax Bolt versions have same h/w configuration, switch off the phone, then press and hold VOLUME DOWN(-) button, and while press-holding it, press POWER button, keep holding both buttons. An 'exclamatory sign inside a triangle with a phone icon' should appear on the screen after 10-20 seconds. This is the recovery mode. Tested in Micromax Bolt A26. Connect the phone via USB cable to PC. Open ADB tool on command prompt, and type 'adb devices', it should list your phone with an ID and as 'Recovery' mode. This is the only way I found to interact with the Micromax Bolt phone, since I couldn't find any hard reset key combinations to show up the ClockWorkMod Recovery options on screen. Remember, incase if your phone is soft-bricked/bootloop stuck, and it is non-rooted and USB-Debugging disabled, chances to recover the phone OS and it's data is less, expect to FLASH it with a new compatible stock/custom ROM using Spreadtrum Tool and necessary PAC file using an Auto-Ignition Cable (This can be done without need for Flashing Box). If the phone is rooted/USB-Debugging enabled when it was bricked, then it can fixed just by using ADB tool to wipe cache/user data or any other ops, without necessity for flashing ROM.
I understand how to flashmy GoClever Tab R75 (Horrible device I know, but still) like just putting the files into the device and switching on and whatnot but I dont know how to edit the img file to add a command to clear data partition, could anyone possibly do this for me or provide me with a tutorial on how to do this please? If you need the download link to the R75 file with the .img file message me as I cannot post links yet!
If you dont understand what I mean: I have 2 files now which if I put into my device will update the firmwire and whatever but I need it to clear the data partition so it will delete all information.
Thanks!
Can anyone help or at least point me in the right direction?

Hi
If you want to clear the data without root then boot into recovery mode and factory reset the phone

Hi
Why you want to edit img files to clear data ? Just use recovery to factory reset
To go to recovery ->
1. Turn OFF your tablet
2. Press and hold Volume UP button and Power Button simultaneously, wait until you see the dead android.
3. Press the power Button to go to recovery Mode.
4. Hold the power button and tap the volume UP (you will see the android system recovery menu.)

Theres got to be someone who can help me?
:crying:
So first off, I like Cyanogenmod very much. But also the data on my phone.
Now the problem is, I didn't do the update properly and now it's stuck in a error loop.
I have an idea how to fix it, but first I want to get all my data off my phone. But I can't get in.
If my phone is on in the error loop I cant enter my phone because it's locked, just like if you haven't enterd my pin or something like that.
Does anyone know a good solution for me?
Use the file manager in twrp.
I wish I stole my HTC M9.

Turn off the phone if can't remove the battery. Then put the battery inside and press and hold power+home+volume up. Then you are in recovery. From here connect your phone using charge cable to a pc and then you have access your files. If didn't wipe system+data+cache+dalvik cache and flash a working rom and you're in. Also can copy your files to SD using twrp file manager or aroma file manager in CWM.
If I helped you hit the tnxgood button.

Allready tried, doesn't work.. Can't enter it
If I am in recovery I can't detect it. If it is on, I can't see the data..
Everytime I enter recovery it just starts installing the update I placed in /dload, but I can't delete this as I can't access my phone using my computer. Is there anyway I can get into the bootloader/fastboot mode without using ADB or accessing the system?
if folder dload is on your internal sd, you can use factory reset to clean -> press volume up and power on together for a few seconds to start this procedure.
this procedure will delete your system AND all your data on the internal sd!!! Caution!
or...
if folder dload is on your external sd card, remove it until starting recovery.
BTW: why it seems not possible to connect your Honor 7 to your pc? Anything missing or unknown procedure?
you know, that you will be able to go into boot mode with connecting usb to pc and pressing vol down until rebooting your device.

How do you enter recovery? Pressing power + vol up?
Never heard that this combo always starts installing update automatically so wanna clarify a bit.
For solution, as said above just delete dload folder and it won't install the update.

Do you have an sd card? Or usb drive with a usb otg connector? If so, (Not sure if cm recovery us close to twrp, but if it is) then you should be able to copy the data folder to one of those and then flash a new Rom and then copy and paste some of the directories. Orr do a nandroid backup if /data, and then flash a new ROM and restore that data backup afterwards. They would have to be the same Rom as you have now though
Sorry it took me so long. Next time quote me so I get a notification

Hold down a set of buttons (Not sure which ones for you, but force restart it and then switch to buttons to boot into recovery. Google the button combo )
How did you flash cmw recovery? Should be the same as that

I found this guide on how to flash twrp and root, you shouldn't worry about rooting until you get booted up first... As for the force reboot, I couldn't find out how to force power it off, so try some of the following:
- Take our battery (if there is a removable one)
- Hold down the volume down and power simultaneously for about 10 seconds (maybe less, maybe more)
- If there is a physical home button, try holding volume down, power and home. (Or volume up)
Once powered off (when the screen turns off, you maybe have to be quick before it restarts. If it does just re-power it off and try again) then hold down power and volume up to boot into recovery mode. You shouldn't need twrp if you can boot into cmw. But I do recommend it when we are finished...
You'll also need a custom (or stock) ROM to flash. I'll show you how to push to your phone with adb if mtp doesn't work in cmw.

Alrighty so if you have fill adb drivers than great, if not this should still work fine...
Download this: https://androidfilehost.com/?fid=673368273298958289
Has adb in it, ignore all the root stuff. So extract the file to your desktop and open the folder. Put your ROM in the folder and name it something easy like rom.zip (important it's not rom.zip.zip)
When in the folder, hold shift and then right click inside the folder and select "open command window here" and then type "adb devices" and make sure something comes up with a ton of random characters. If nothing comes up (make sure phone is plugged in lol) then install your phone's drivers. Then try again. Next type this exactly as follows (if you names it rom.zip)
Code:
"adb push rom.zip /sdcard/rom.zip"
**NOTE the space between rom.zip and /sdcard**
This should take awhile, depending on how big the file is. You should see a pulsing dash in the left side of the command prompt. It will stop blinking and bring up a new line when done. Now go into cmw and flash the file in your sd card (rom.zip)
Going to sleep, I'll reply early in the morning before school

Root.bat is for Samsung yes, but adb is universal. We aren't worrying about root
Since you didn't have adb installed this is a lightweight version so you don't have to install it. This is just the file link I had on hand
