[Q] 4.4.2 downgrade to 4.3 - backing up ROM before downgrade??

Hi
I have a standard motorola moto g 8gb unlocked phone - not tied to any uk network on 4.4.2 .
I wish to downgrade to 4.3 or change the rom to another rom.
Before i do this what is the easiest/simplest way to backup the ROM (o.s) which is not root'd ?
Or do I have to root the phone?
Also do I need to install drivers or not for the phone as Windows 7 sees the phone fine in explorer/my computer when the phone is turned on - i can drag drop files on there no problem
Thanks in advance.

a way to backup without root? Yep.
a way to backup without unlocking the bootloader? Nope.
You see, for everything you need the bootloader unlocked: rooting, flashing, etc...
so if you want to backup anything you first need to unlock the bootloader to flash a Custom Recovery and then do the backup and that can be done without rooting the phone, or touching the rom at all.
You will need the motorola drivers and adb:

Hi
ok made a bit of progress.
never thought it would be so much of a mission !
got the bootlocker unlocked..
now how do i install the clockwork mod or twrp app sorry for my ignorance. i have followed the links you've kindly posted me.
i am familiar with dos commands etc. - so that doesn't phase me.
i've downloaded the apps from a site both clockwork and twrp - .img files - do these have to be installed via command
prompt with fastboot to install them respectively whilst the phone is plugged in with usb cable in the bootloader phase?
are there not any "windows" apps that can install these apps?
Thanks in advance
You don't have to install both of them!

and also
You do not have to install both the recoveries, either cwm or twrp not both of them!
you said you unlocked bootloader, that means you have adb installed with fastboot
copy the .img file for twrp/cwm whichever you prefer to the folder where adb is installed
rename it to recovery.img
then turn off the phone and boot into bootloader and run
Code:
fastboot flash recovery recovery.img

Leagoo Lead 3 root

I got root on my Leagoo Lead 3 using the following method a user had for his Leagoo Lead 1.
http://forum.xda-developers.com/showpost.php?p=54321112&postcount=3
Edit: skip the first step and only proceed to step two. Your device will try to boot into fastboot once or twice. When that's done, open mtk uncle tools on your device and then head into engineering mode and click root in the user/root menu.
Hope this helps anyone who needs root.
Root failed for me
Hi rukusx7
In my case it has failed... can you help me, please?
My phone had installed X applications, google account... prior to root...
Fisrt Step: Bootloader unlock...finish OK
When I run button of Bootloader unlock my mobile init in mode fastboot, make tasks and finish ok and mobile still in fastboot mode​
Next Step: KingoRoot.... finish Failed.
When I run kingoroot, my mobile is in mode fastboot ¿it's ok?...make tasks and after a long time finish with failed​My sencond attempt is to run kingroot with my mobile ON as usual but kingoroot failed too..​
I think my problem is the step 1. How can I check the step 1 is correct?
Thanks in advanced for your help.
I really messed up with explaining myself on that. I really have NO idea how any of that root guide worked for me.... I completely omitted the first step. I'm truly sorry if my misinformation has caused you any troubles.
Start sony bootloader unlocker and run it with your phone connected.
It will restart your phone to fastboot and then it remains idle.
Keep your phone plugged in, switch it off and boot manually into the fastboot (power + vol up)
From here the unlocker will proceed unlocking.
Step 1 done.

This is the only part of the tutorial I followed.
Now open kingosoft root connect the phone and let it do its thing.
At restart of the phone kingosoft will show on screen a message like "checking root status"
Launch mtk uncle and enter engineer mode.
Go to log and debugging tab ans select user2root
Select Root.
Now kingosoft will tell you that root is succesfull and restarts the phone.

Hi
I also have Leagoo Lead 3 and i successfully rooted the phone. First step finished OK, but on second step with Kingo Android Root i had a problem
At restart of the phone kingosoft will show on screen a message like "checking root status"
Launch mtk uncle and enter engineer mode.
Go to log and debugging tab ans select user2root
Select Root.
Now kingosoft will tell you that root is succesfull and restarts the phone.

I selected root but nothing happened, it continued to say "checking root status", "connecting to device" and it took lot of time so i closed the program to start again but then i had another problem. It didn't want to connect with device, it tried and tried but without success.
-- my steps --
- When i started Kingo Android Root for first time it downloaded HTC driver so i downloaded latest driver HTCDriver_4.2.0.001.exe ( [DRIVERS] Latest HTC Drivers [4.2.0.001] )
- I rebooted the PC ( now i don't have unknown device in Device Manager)
- On phone launch MTK Uncle and select User (on my phone it is = ENGINEER MODE/ENGINEER MODE (MTK)/LOG AND DEBUGGING/USER2ROOT/USER)
- Go to Settings / Developer Options and turn on USB Debugging (if it is already turned on, turn it off and then turn it on again)
- Start Kingo Android Root, connect phone to PC ( try to use usb cable that came with mobile phone ) and do everything like in step 2
Now open kingosoft root connect the phone and let it do its thing.
At restart of the phone kingosoft will show on screen a message like "checking root status"
Launch mtk uncle and enter engineer mode.
Go to log and debugging tab ans select user2root
Select Root.
Now kingosoft will tell you that root is succesfull and restarts the phone.

Click to collapse
If it cant establish connection with phone try to reboot the phone ( don't unplug the phone from PC ) and when it reboots, check again if USB Debugging is turn ON.
I rooted my phone at second attempt but that doesn't means that it would work for everybody or that this steps are needed.
Yeah, it took me a few attempts to be honest. I also used a data cable from my oneplus one.
I'm happy there are more people to help with this, so we can get some proper root instructions.
Also new firmware is on their site. I know nothing about mtk devices. How can I flash it if I can't find how to get into fastboot mode manually? (Why I omitted first step)
Edit: Quick Reboot from playstore will boot into fastboot mode for you!

Leago Lead 3
-- On my phone (when is turned off ) if i press ( vol+ ) and then ( power ) key it will enter recovery but in recovery menu, ( power ) key doesn't work.
I can only go down with ( vol- ) and select with ( vol+ ).
-- If i press ( vol- ) and ( power ) key *(when is turned off)* i will enter something similar to recovery, but everything is on Chinese language.
Here i can go up and down through the menu and select with ( power ) key.
I only know that word at the bottom means EXIT.
I also don't know how to flash, i think we need to use SP Flash Tool or MTKDroidTools but they look complicated.
Successfully installed Carliv custom recovery. You need root first though.
[PORT][RECOVERY] Carliv Touch Recovery v-1.5 for porting to all MTK phones
You need Default [UTIL][WIN][MT65xx] MTK Droid Root & Tools | MediaTek Android Smartphone
I didn't manually do the work. I used the automated porting tool. But to get root shell, I had to run the MTK tools. It notifies you that it can get you root shell by clicking root. Then you run CTRv-1.4 (the automated porting tool) and it can gain root shell access now. It automates everything and boots you into the new CWM.
By this point, if you can get root, you should have everything you need. I installed adb using
[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.3
I've also semi deciphered the Chinese menu. So from the first menu entry.

You can build your own custom philz with either the recovery.IMG from your own phone or you can choose one manually. Leagoo has updated firmware for this device on their website. I suggest an update first then root and then recovery.

No need to unlock bootloader. Install mobile uncle tools from play store to device. Pick your favorite rooting tool. I used kingo root. Run kingo root. The app will try to reboot the phone for some fastbook work, when this fails, it will boot back into android. This is where you open mtk uncle tools, head into MTK engineering mode, scroll right until you see user/root. Tap that to choose root and the rooting tool will continue.

I've uploaded my philz touch I "made". I used Easy Magic Philz Installer for mtk devices to get it done.

You can try flashing with flashify from the playstore, or I used the SP_flash tool. You just uncheck what you dont want to flash.
This is where things get good for you. In philz recovery, you can use the built in tool found in the Advanced Menu to Re-root the system. Once completed, reboot and install supersu from the playstore, it will notify you to install the su binary. Reboot and you should have root. Or at least I did.
I used this method AFTER applying the update on the Leagoo website. Which I highly recommend before ANY updates. all updates go OTA after this release. NO idea if update will work after rooting your device or installing CWM.
For using flashify the phone need to be rooted. I started the process with SP_flash tool and nothing, not even 1 %, it's been like this for hours. I tryed every method for rooting and flashing ROM that I could find on internet. I'm starting to be hopeless. Can you upload me you're backup file. I think that i could put it on SD CARD and restore phone to your backup file.

[Completed] MOTO X PLay Root gone wrong!

Alright, I wanted to root my moto x play and and i tried doinng it using this tool. http://forum.xda-developers.com/mot...l-windroid-universal-android-toolkit-t3206881
Unlocking the boot loader worked fine and it got unlocked. After when i flashed on twrp, it prompted to me set up the device and so i did turning on usb debug mode. After i flashed on supersu and when i tired going into recovery mode twrp was not there. So i flashed on supersu first and then twrp and finally it worked. After i ran supersu and booted the device it doe not get past the boot loader warning. the device is readable in adb but i cant sideload and push anything onto /sdcard does not exist and when i side load i get error:closed. in device manager the phone shows up as mtp usb device but with a yellow triange. when i run the command adb usb the driver install fails. i really hope this is not a brick and i can recover.
sidenote= the sd card does not work so i can not flash another rom.
please help.
Found fix.
Update: not bricked. Flashed on stock ROM using a otg cable.

htc one e8 dual sim[India] stuck at boot screen after OTA update[android 6.0]

Hello,
Today I got notification for my marshmallow update for my HTC one e8. But I had TWRP recovery in my mobile and S-ON. and somewhere on youtube I watched a video how to get OTA update on rooted HTC ONE devices so follow the following steps :
1) Get back to your stock recovery : - which did by taking the recovery.img file from update package and flashing the recovery using fastboot.[which removes twrp with this new recovery].
2) then i started installing the update which I think successfully installed.
but when it rebooted it stuck at the boot screen. Then after 3-4 hours I factory reset my cell by visiting boot loader. But nothing happens and now I am stuck . Please help me how to recover my phone.
Also I am not able to change back the recovery to TWRP, as in fastboot device is undetectable.
so is there any way to get back my phone from TWRP backup which I made earlier when I installed TWRP
Solution
I faced a similar solution and i'd suggest you to do the following
The main issue was that adb debugging was off so its wasn't getting detected in the fastboot shell in the pc.
Install htc mobile drivers on my pc (google it, you can find this easily).
Keep the phone in HBOOT mode and connect it to the pc. Open device manager in the pc, you will now see that your htc device is now listed there.
Now open the command prompt from adb and fastboot folder. Switch the phone into FASTBOOT mode.
Now give the command: adb devices .
Do not worry if your device is still not shown in the list of devices attached.
Give the command : fastboot reboot-bootloader
Your phone should reboot in the bootloader mode again. If this happens, it confirms that the device is successfully connected to the pc . :good:
Now you flash custom recovery in your phone using the command :
fastboot flash recovery "<name-of-the-recovery>.img"
Then reboot the phone using :
fastboot reboot
Now try to enter into recovery mode. Your custom recovery will open up.
Now you can restore a twrp backup (I'm assuming that you have one. It is always recommended to have a backup of your phone whwnever you root your phone).
Reboot and you are done !!

hey listen to update your cellphone to MM using OTA updates you need to have a re locked bootloader or you should not have any SU binaries in your phone so to do this you need RUU. If you are able to connect your cellphone to ypur PC and able to use fastboot then using fastboot just relock the phone using above mentioned commands and then use RUU to get back to stock lollipop ROM and the start updating using OTA. I did yesterday all these and now I have MM in my cell and its working fine with sense 7 ( which means no restrictions on themes).

Dear all Dual SIM Indian M8SD users,
Please could you share your experience of updating to MM? I am having no network connection with SIM slot 2. SIM slot 1 is fine.
I then downgraded to Lollipop by flashing the RUU via fastboot after erasing the phone memory via TWRP recovery. Both SIM started working perfectly again. Then did an OTA update in four stages (from 2.33.720.3 to 2.33.720.4 to 2.33.720.6 to 2.33.720.8 to 3.06.720.2 MM) to Marshmallow.
Same problem with SIM 2 again. In the meantime, have tried various other tweaks (all combinations of settings/ removing SIMS and back in/factory resets etc.). None works.
Any help and ideas will be really appreciated.
Many thanks.

Pixel 4a stuck in fastboot loop after trying to flash kernel

I was trying to follow this guide: https://github.com/felikcat/unlimited-hotspot
I used this kernel: https://forum.xda-developers.com/t/...ribute-for-google-pixel-4a-a11-a12-l.4258269/
My device is now stuck in a loop where it will boot to fastboot, but no matter which option I select (aside from barcode and power off) brings me back to the fastboot. I'm unable to boot into recovery mode.
My computer is unable to find my device with adb and fastboot.
Any help would be greatly appreciated
I realized I did not have the USB drivers installed for my device. After installing, fastboot on my computer is able to detect my device, but I am unsure about how to proceed from here
Okay so I followed this guide: https://forum.xda-developers.com/t/guide-unlocking-downgrading-to-a10-twrp-root.4233275/
and was able to complete is successfully. My phone is now rooted on android 10. I have a couple questions
My phone was rooted and on android 11 prior to this incident, but it was so long ago that I don't remember how I did it. Is it possible to get back to android 11?
My second question is that I'm wondering if it's still possible to follow that previous guide, preferably without breaking my phone this time
