[Q] Motorola Moto G Lost OS

Hey guys,
Recovery : TWRP 2.6.3.3
USB Debugging : Off
Cannot connect to PC.
Recently, I accidently formatted my Moto G through the advanced wipe and I selected all the partitions to be wipe such as dalvik cache, data, internal storage, cache and system. And now my Moto G doesn't have any OS in it and I can't reboot it at all. I don't have any idea what to do right now. Can someone please help me how can I install a new rom for my Moto G so I can use it like a normal phone again. Please no harsh words, I know it's my mistake and I really need help.

If you are able to go to recovery(which you should be able to do), download any custom ROM of your choice like PA, CM, SLIM etc.. flash that rom by following the Installation instructions in the thread. YOu should be able to get the phone back to normal. And if you want the stock ROM, then download the stock files and flash it, you might loose custom recovery, then follow the same things you did to get TWRP in the first place.

I would if I could. The problem is I formatted the whole phone which included the internal storage too. My CM Rom is in the internal storage and it's already deleted. I tried to connect my phone to the pc so that I could transfer a rom into it but failed cause my pc won't recognized my phone as the media transfer devices. It's only recognized my phone as fastboot falcon s. I've installed Motorola Device Manger but it's also failed. I also tried to install using adb sideload but I got device not found error and my phone doesn't listed in the device attached after I typed 'adb devices'. For the OTG and memory card reader method I haven't try yet because I don't have any of it.

What does it say when you try
Code:
adb devices
or
when you reboot to bootloader with phone connected and type
Code:
fastboot devices
If it shows a device for fastboot devices then follow this to flash back to stock. Make sure you download the right stock firmware for your phone.

when I type 'adb devices' it give me an error saying that my device is not found. for the 'fastboot devices', I tried it too but also an error. It say, 'fastboot' is not recognized as an internal or ecternal command, operable program or batch file.

It seems like you dont have fastboot files. Follow the same link that i posted in the previous one. It has portable adb & fastboot files. Download that and then follow instructions. You should be able to get to fastboot. Once you are there the job is almost done. Hope it helps
Edit: Here is the link to download and install the minimal adb & fatsboot files

I've followed all the instructions but my phone still not rebooting. When I try to reboot it, it only show me the warning of unlocked bootloader screen, black screen, warning of unlocked bootloader screen then dead android screen. What should I do now?

It means your phone is in fastboot mode and recognised by your PC. Next you'll have to "fastboot flash" the necessary files to install a recovery and a system, and you should be good to go.

Few weeks back I ****ed up soft bricked my phone had kindda same issue when I switch my phone on I get a dead android logo. Gave to the service center in India and got a replacement a new xt1033
P.s I was trying to root and my warranty was void still got a new one try your luck bruhhh

I only want to connect my phone to my pc so I can transfer any rom to my phone so that I can install the rom. But right now, my pc won't recognized it as media transfer that's why I can't transfer any file to my phone. I tried everything. I've installed motorola device manager but all that I got is motorola adb interface that make my phone can connect to the pc when in bootloader mode.I don't have any OTG cable or mobile sd card reader.

Hey, I've done all of the flashing instruction from the xda forum link that you gave me. My problem for now is, why is my phone not rebooting? The only thing that happen after the flashing is my phone only show the 'warning bootloader unlocked' and the dead android with red triangle screen. It won't boot into the stock rom that I've flashed. The stock rom/firmware that I used is correct. Please help me.. I really need to use my phone.

K there's a resolve for this...Provided that you haven't ****ed up your phone by making it hard bricked...
1 - Get a freaking rom and sideload it through TWRP to boot into system...
+ Download a ROM
+ Put it in the same folder as ADB and Fastboot and rename it to something easier that you can type exactly (ex: 1.zip, backup.zip...)
+ Shift + Right Click at a blank field in the window
+ Choose Open Command....
+ On TWRP, go to Advanced => Sideload => Tick the 2 boxes => Swipe to start sideloading
+ Type in adb sideload <yourzipname>.zip on the cmd (on your computer)
+ Wait for the process to finish, then you now have a working phone...
2 - Follow this guide using the proper firmwares that match your original one : http://forum.xda-developers.com/showthread.php?t=2542219

Your PC will not recognize it as media transfer / storage while you are in bootloader / fastboot mode, its perfectly normal. When you type fastboot devices it should show you a number which means it working as intended. This is an old thread but it shows how to transfer your ROM to sdcard via adb push command. http://forum.xda-developers.com/showthread.php?t=1667929

The output of the "fastboot devices" command clearly shows your phone is recognised by your PC. As I said all you need to do now is use the correct "fastboot flash" commands to restore recovery and system. Tutorials can be found in this forum.

Thank you.
I would like to say thank you to all peoples who help me solving my lost os problem. Thanks for all the informations. My moto G is working perfectly normal right now.

Forget about trying to use recovery to flash. Download the fastboot images and flash with fastboot. See section 8a of my guide:

Hope this helps. Go to their website and download the fastboot ROM of your desired phone and desired locale. There you can also find the MiPhone Flasher exe file. Run that file on your PC, connect the device with a USB cable when in Fastboot Mode, the application will detect the device, then provide the Downloaded ROM path and hit Flash. within 2-3 mins you're good to go

I have same problem with my mi 4i

oneplus one
variant 64gb
os cyanogen 12

Is it a stock COS ROM?
I suggest you to dirty flash the rom without overwriting /data
So if you flash the zip it's OK but if you flash from fastboot be aware of not flashing userdata_64.img

yes my ROM is stock rom .... what is dirty flash please guide me....

-Is your bootloader unlocked?
-What recovery do you have?
Available signed flashable ROMs: https://forums.oneplus.net/threads/mirrors-for-official-cyanogen-roms-ota-updates.141825/
Find yours or just chose one, and download the signed flashable zip, then copy it to the phone (while in recovery the phone has MTP enabled on the PC) then just flash that ROM from the recovery, this will overwrite system but won't touch data and most likely fix the bootloop.
Before rebooting after flash wipe cache and dalvik just in case.
Next time do a nandroid backup if you have sensible data. I usually don't keep anything important on the phone, everything on google drive.

I don't know my bootloader is locked or unlocked.... when I try to connect phone in recovery and connect USB nothing happen but when I restart phone and set is on onelus logo and attch usb PC recognized as mtp USB device but driver failed....

Which recovery? Stock or twrp? I'm not sure that when you have stock recovery on the phone gets recognized as mtp on the PC.
I can think of adb to push the ROM zip on the PC but if you claim it doesn't get recognized I have no clue. Are you sire you have the google USB drivers installed?

Install fastboot,adb and google USB drivers : https://drive.google.com/file/d/0B9fZIF6vzIBzT2ZtZkNSVFI5ZHc/view?usp=drivesdk
Reboot the pc
Download twrp: https://dl.twrp.me/bacon/twrp-3.1.0-0-bacon.img.html
Reboot in fastboot mode.
Open a command prompt on the PC inside the folder where the downloaded recovery is.
-Find the folder (maybe user/Downloads)
-while holding shift mouse right click inside the folder
-select "open command prompt here"
Connect your phone and type in cmd
Code:
fastboot devices
If you're lucky and did everything correctly then your phone should appear and you can continue, if not uninstall the drivers you previously had and kingroot and whatever minitool you used and try again.
Now that the device is visible
Code:
fastboot flash recovery twrp twrp-3.1.0-0-bacon.img
Phone should reboot. Just turn off and boot into recovery and hopefully you'll see twrp.
Now connect the phone to the PC an you should see the mass storage and you'll be able to copy the ROM zip there.
Now just flash the zip of the rom and you're done.
U cannot assure you that it will fix the bootloop but it's your best choice.
In the future:
-Never use kingroot or other ****ty mini tools. CMD and manual flash are always the best choice.
-Do a backup if you are not confident with this kind of stuff.
-Don't keep too much stuff on the phone. Use google drive. And services to save contacts, notes images videos.

This means your bootloader is still locked so you basically can't do anything. To unlock it you would need to factory reset. So your only option is to try installing the ROM via adb on the cyanogen recovery.

Try to push the zip from adb to /sdcard and then flash the zip through the recovery (which technically should do it since it's a stock ROM)
This will result in a "dirty flash" which will not delete data.
This is your only option in the current state of your phone, if you had rooted your phone properly without kingroot you would have booloader unlocked an you would've had more options. If this doesn't work you are forced to factory reset. And use this opportunity to unlock bootloader with
Code:
fastboot oem unlock
Which due to security measurements will delete all the data.

Before you going to flash anything using adb or something, do this.....
1. Turn off your phone completely.....
2. Connect the charger and let it charger for 10 minutes
3. While the charger is still connected, press the power button (turn it on)
4. Wait....
If the phone boot normally while the charger is still connected, unplug the charger and waits....if the phone goes back bootloop after a few minutes and hours without charger connected then your problem is a dying battery not software....buy a new battery and once your replace it, it will solved your problem without having to flash anything via adb or recovery...it also can save all your data....

That depends if you are running oxygen os, you can't flash an OTA of OS that you are currently not running. To dirty flash you have to use the same version or distribution of the OS you are currently running.

screwed up , any assist appreciated

hello
you cant flash fastboot rom in twrp . download one that is not fastboot . links in this thread : https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244
about not recognized as an internal ... . make sure you installed adb and fastboot drivers .

lalala
i can't get a recovery flashable zip to the phone now anyway.
i did reload adb and oneplus drivers this morning and then again after your reply to make sure.
i did notice the phone shows as a oneplus6 in devices while in twrp but when i switch to bootloader it changes to just android device?
So still stuck.
Between last night and this morning have many hours trying to get it working somehow.

no twrp just bootloader now
rebooted the phone and lost twrp.
tried to flash it and it says failed remote failed to load authenticate boot image :load error
i need to start fresh somehow
*I can't even turn the phone off now, it reboots to bootloader instead!!!!
