This thread exists to give everyone that is just now getting around to taking advantage of their devices the opportunity to do it right the first time while also keeping all the necessary material in one common place. As always: Know what you're doing. Know what device model you have. Know you and your devices limits.
If followed correctly, this 5-step guide can be a very useful tool. These steps are listed in the order in which they should be completed. The intent is to seamlessly backup, root and flash, leaving as little room for error as possible. This process will erase and/or reset everything on your device. All steps are assuming you have backed up your contacts, texts, pictures, videos, etc. I do not take credit for any of this material or information. This is all the work of good people that I have simply brought together. Cheers!
**WARNING!** All information and attached links are for the I747 and I747M ONLY! No one here is responsible for anything that may happen to your device. Proceed at your own risk.
>>>>>>Before you begin, make sure your S3 has USB Debugging Mode switched on<<<<<<
STEP 1: Backing up your IMEI/EFS/NV
Part 1. Having a corrupt IMEI can be a real pain. It seems to happen randomly and having the radio go down on a cell phone really defeats the purpose of owning one. Thankfully it is not a problem that is overly common. Unfortunately, it does still happen. Since it is simplest to be on stock for this attached method, I have listed it as step number 1.
At the end of the "Instructions" section there is a video demonstration. Check it out first.
Part 2. Having a copy of your functioning EFS folder is also something every user should have. A great way to do this is to download an app like Root Browser or Root Explorer and copy the efs folder from your device to either your external micro SD card, your computer or both. This will allow you a much smoother transition back into a fully data-capable and functioning phone in the event your IMEI/EFS is ever corrupted.
STEP 2: Rooting your device
For those of you who want to get most out of your Galaxy S3, you will certainly want to root it. Rooting your I747 gives you lots of benefits like full control over your phone, ability to install custom ROMs, and much, much more...that's why you're here right now reading this. You want it all.
The attached link may be intimidating to you initially, so read over the page a few times to become familiar. Near the top of the page, the second paragraph links you to a video of the rooting process. Watch this to understand better what to do and what you should expect to see during these root procedures. After downloading Odin (the link is just below the video link), just follow the first 2 steps (1. Download the file to flash and 2. Unzip the file contents and flash the rooted firmware) and then return here to continue on to step 3.
**If you want to have root access only and are not interested in a custom recovery, you can stop here.**MrRobinson's debloating thread can be found here if you wish to remain
stock/rooted-only but cleaner, with less bloatware and without unused apps absorbing resources.
A custom recovery is required and TWRP is recommended
STEP 3: Installing a custom recovery
A recovery image is the system level software for your Android that lets you perform several maintenance and recovery tasks. The stock recovery image is quite limited in what it allows you to do and therefore, flashing a custom recovery image is required to gain full control of your device’s administration. A custom recovery image allows you to perform the following tasks:
- Wipe your phone’s data (Factory reset) and cache
- Make, restore and manage backups of your phone’s operating system and software
- Mount, unmount and format your phone’s internal as well as external storage partitions
- Install a custom ROM or application from a zip file to your phone
- Wipe Dalvik cache and battery statistics
- Make logs for error reporting and debugging
The 2 most common custom recoveries are listed here. Everyone has a preference but they both work well. Take your pick and download from the Play Store.
**ClockworkMod (CWM)** --- OR DOWNLOAD THE APK DIRECTLY HERE (Recommended)
1. Open Rom Manager and tap on Flash ClockworkMod Recovery option in the app.
2. You’ll be asked to select your device, select your device name.
3. As soon as you select the model, it should begin installing the recovery.
4. When it has done installing the recovery, you will get a message for the same on your screen.
*NOTE: I do not recommend Rom Manager as a tool to do anything but just install and update ClockworkMod Recovery Do not flash ROMs from Rom Manager.
**Team Win Recovery Project (TWRP)** --- OR DOWNLOAD THE APK DIRECTLY HERE (Recommended)
1. Once the download is complete launch Goo Manager.
2. On the top right of the screen there is the “options” menu.
3. Tap on options.
4. Then, click or choose the “Install OpenRecovery Script” option.
5. Select “yes” on the prompts that will follow. Now, the app will download and install TWRP Recovery on your S3
*NOTE: I do not recommend GooManager as a tool to do anything but just install and update TWRP Recovery Do not flash ROMs from Goo Manager.
STEP 4: Making a Backup (Nandroid)
Making a nandroid will allow you to try out new ROMs while still keeping a safe backup in the event you experience issues during or after the OS installation. Be sure your device is fully charged before proceeding onto the backup and flashing procedures.
1. Power off your device.
2. Press and hold Volume Up + Home + Power buttons at the same time.
3. Release the power button when the device vibrates and you see the blue script in the top left corner
4. You are now in custom recovery.
5. In CWM go to Backup and Restore and select Backup. In TWRP select Backup. Name and select the options you want. Swipe to backup.
6. After backup is finished, select reboot system now or stay in recovery to continue with this guide.
*NOTE: Be sure to save a copy of this backup to your computer and/or micro sd card. Having a recent backup saved to your computer and micro SD card can be useful if something happens to your phones internal memory.
STEP 5A: Wiping your device
When flashing any ROM, it is always important to follow the proper wipe procedures in order for everything to function properly. There are various levels of wiping based on what sort of transition you may be making. In this guide, I will list the procedures for a full wipe, presuming that you are coming from the stock firmware and changing your OS completely. This is all assuming you have made the appropriate backups. ALWAYS perform the appropriate wipe before flashing a new ROM or update!
1. If you are not already in recovery, boot in now (Vol Up + Home + Power. Release the power button at vibrate and when you see the blue script in the top left corner).
In CWM:
2. Select Wipe data/factory reset
3. Select Wipe Cache
4. Select Advanced and Wipe Dalvik Cache
5. Select Mounts and Storage and format /system
6. If you are transitioning from 4.1 to 4.2 or 4.2 to 4.1, you must also format /data. You will lose all personal data so back it up first.
In TWRP:
2. Select Wipe
3. Select Factory Reset and wipe
4. Select System and wipe
5. If you are transitioning from 4.1 to 4.2 or 4.2 to 4.1, you must also select Data and wipe. You will lose all personal data so back it up first.
STEP 5B: Flashing a custom ROM
First, read up on a couple ROMs you're interested in. Make sure they are for your model. Understand that the newest ROMs often still have some small bugs still to be worked out. Once you have decided on a ROM:
1. Download the ROM - If you are downloading a stock/TouchWiz-based ROM, Google Apps (gapps) will be included. If you are downloading an AOSP-based ROM, be sure to download the appropriate gapps as well.
2. From your PC, place the ROM/gapps on your internal or external SD card. Remember where they are.
3. Boot into custom recovery (Vol Up + Home + Power. Release the power button at vibrate and when you see the blue script in the top left corner).
4. Perform the wipe listed above if you have not already.
5. From the main recovery screen:
>>CWM - Choose the "install .zip from SD Card" or "install .zip from external SD card" option (depending on where you placed the files) then navigate to the ROM file, select it and confirm.
>>TWRP - Choose Install and locate the desired ROM on your internal or external SD.
6. If you need to flash gapps, repeat step 5 and select the gapps package.
7. Reboot system. It will take several minutes to load so be patient and don't worry. Once the phone is booted, let it sit for 5 minutes, reboot and enjoy!
>>>>>Fixes and Additional Resources<<<<<
Post #2 will, as it claims, contains further useful information and links that will hopefully restore your device and continue to make your device-modding travels safe, smooth and fun. Please do not disregard the initial purpose of this thread and all the useful steps and information listed above. Post #2 is for those who have encountered common issues and errors, and are comfortable and familiar with all the required procedures for successfully modifying their devices. Cheers!
Latest AOSP/CM/AOKP flash error - Updating Your Bootloader
For continued support and updates, read mrhaley30705's bootloader advisory first, then follow the Task's directions outlined in this thread. This is intended for those not on the necessary Jelly Bean bootloaders, allowing them to flash future [CM] builds.
Bootloops
Bootloops are mainly caused because system files are conflicting and interfering with each other. This instability causes crashes at the boot sequence.
To find the cause of a bootloop you have to think about what you did before the issue began. After flashing a new rom, stock firmware, kernel or restoring a system backup?
Method 1
1. Boot into recovery
2. Wipe Cache
3. Wipe Dalvik cache (custom recovery only)
4. Reboot your phone
If the problems still exists and you're sure it's not related to the ROM, then you need to wipe data as well:
Method 2
1. Boot into recovery
2. Wipe Data
3. Wipe Cache
4. Wipe Dalvik cache (custom recovery only)
5. Reboot your phone
Method 3 - This last method involves restoring your backup in order to correct the conflicting software by replacing it with a functioning platform
1. Boot into recovery
2. Wipe Data
3. Restore backup
4. Wipe Cache
5. Wipe Dalvik cache
6. Reboot your phone
Setting the wrong permissions or not adjusting permissions can also induce this error. Android is very dependent on the right permissions. If you adjust file permissions incorrectly you could find yourself in a bootloop. An easy fix is performing the "Fix permissions" option in recovery under Advanced. Be sure to mount the partitions before running the fix.
Status 7 error
When you receive a Status 7 error in CWM or TWRP, the most common reason for most users is that their recovery is not as up-to-date as the ROM requires it to be in order to install. There are a couple different ways to fix this, depending on each persons situation.
You've wiped everything on your device, removing your OS, and now you're receiving the error:
If you have a micro SD card, this fix is simple. You can download an up-to-date flashable CWM or TWRP recovery zip, place the file on your micro SD, flash the zip, go to Advanced and reboot recovery.
You've simply tried dirty flashing a ROM or ROM update and have only wiped data, cache and dalvik:
Use the above technique to update your recovery or boot back into your S3 to update. For CWM users, head to Rom Manager. If you use TWRP, hop into the Goo Manager app. Once you've applied the update, boot into recovery and flash the desired software.
Soft brick - Stuck at glowing Samsung logo
There are two types of bricks – the softbrick and hardbrick. The softbrick can be recovered if you can still get into download and recovery mode. Additionally, getting stuck at the Samsung logo is another one our most common issues seen. When you flash a stock ROM with Odin, your /data will be kept. This means your old dalvik cache is still being used for the new system files. If this is still possible, then boot into recovery and try these methods first:
Method A: Wipe
1. Wipe Data
2. Wipe Cache
3. Wipe Dalvik Cache
Method B: Wipe and Restore
1. Wipe Data
2. Wipe Cache
3. Wipe Dalvik Cache
4. In CWM: Select Mounts and Storage and format /system. In TWRP: Wipe System
5. Restore your backup
6. Wipe Data again
7. Wipe Cache
If neither of these methods has got your device back up and running, you will need to restore the phone with stock firmware via Odin. Make sure the battery is fully charged and follow these steps:
1. Download and run Odin on your PC
2. Download the stock firmware for your device
3. Boot into download mode and, when prompted with the warning, press Volume Up to continue. To access download mode, power down the phone and hold down the Volume Down + Home + Power buttons
4. Connect the phone to PC via USB. Make sure you can see the highlight COM:ID box once the device is detected
5. In the tickable option boxes, ensure ‘RE-Partition’ is unticked. Only ‘Auto Reboot’ and ‘F. Reset Time’ need to be checked off
6. Now click the PDA button and select the tar you downloaded
7. Click on “Start” to flash the stock firmware
8. Wait until the flashing successfully finishes and you see a word ‘PASS’
9. Unplug your device, pull the battery, replace and immediately press Volume Up + Home + Power to enter stock recovery. Release the power button when the device vibrates and you see the blue script in the top left corner
10. Wipe data, cache and wipe Dalvik cache (under advanced). Reboot
Low internal memory / Multiple "0" folders
This is a common issue when flashing a 4.2 ROM. Android 4.2 has multi-user support. The 0 folder is user 1. The best way to avoid this multiple folder problem is to always flash from the latest CWM or TWRP recoveries, whichever you prefer. The duplicate folders issue can be solved via the install method listed under the Reverting to 4.1 ROMs? section or as follows, if you've already flashed your 4.2 ROM:
Staying on 4.2+ ROMs?
1. Copy your sdcard data to /data/media/0 and then delete the /0/0 folders
2. When prompted, choose merge
3. Verify there is nothing in the other 0 folder, then you can delete it
4. Repeat with other /0 folders, if applicable
5. Reboot
Reverting to 4.1 ROMs?
1. In the event you are planning on returning to a 4.1.X ROM, I encourage users to make a backup and save/backup everything on the device that they wish to have on their device again after flashing. Save/move everything either to a micro SD card or to your computer.
2.*When you are in recovery and preparing to flash, wipe: data/factory reset, cache, dalvik, format /system, format /data & /media
This will eliminate the OS and all traces of the previous 4.2 data and folders, allowing you to boot into your device with the full amount of available memory and no duplicate "0" folders.
Simple and Fast Wiping Mods
In this thread by Upndwn4par, there are three recovery-flashable wiping tools that you can use while working on your device. They can be incredibly useful tools that save some power button & volume rocker mashing. With the snappy flashing of these zips, you can easily perform a Cache & Dalvik Cache wipe, a Full Wipe or a Full Wipe Factory Reset. These are handy and will ensure you perform the necessary wipe to best optimize your ROM, mods and troubleshooting. Per-wipe details in the link.
Unroot your device
Need to get your S3 ready to return to the manufacturer? Follow this link and you'll be squared away in under 10 minutes. You'll need:
- Triangle Away installed
- The official stock firmware for your device
- Odin installed on your PC
- Your Samsung USB cable, if possible
- Samsung drivers installed on PC
Build your own Must Have toolkit
In the world of rooted phones running custom ROMs, you will find the simple micro SD card to be the best $10 you've ever spent. I would strongly encourage everyone to purchase one of these and build themselves their very own emergency-response toolkit, stored right on the device. To do this, grab yourself a micro SD card and place these files on it:
- Your stock Nandroid backup
- Your most recent or preferred Nandroid running your current custom ROM
- The ROM/gapps you're currently running
- A current flashable CWM 6.0.3.0 / 6.0.3.1 or TWRP 2.4.4.0 / 2.5.0.0 custom recovery
- A flashable stock ROM
First.
Updated OP.
Please share. Lots of posts from beginners dealing with issues related to wrong root methods, outdated recoveries or incorrectly flashed files. Let's help make it a smooth transition by getting them the right procedures. Cheers!
cant find a recovery for SGH-i747M, any tip?
or can i use the same as the att samsung galaxy s3 SGH-i747?
edit
susesfully installed Cyanogenmod 10.1 on my d2ub (Claro Puerto Rico Samsung Galaxy s3 LTE SGH-i747M).
i instaled the last Clockworkmod recovery from the d2att
and flashed the cyanogenmod d2att rom, i just have to manually add my carrier APN settings.
working good so far, will come back 2 morrow and report more.
Very Nice and neatly done. I'm definitely bookmarking this page and help out our future xda members!
Thanks!
Beer,
You should direct people to these as well:
This has all the stock apps for the at&t phone that can be flashed in the aroma installer or pushed to /system/app or data
http://forum.xda-developers.com/showthread.php?t=2185221
This one is makes wiping easier so you know a step wasn't skipped and can be flashed in a custom recovery everytime you flash a ROM. I never get a bad flash using this:
http://forum.xda-developers.com/showthread.php?t=2097365
And also list the most invaluable asset: An awesome file explorer like root explorer or other tools they should also have when flashing
thanks, hednik! will make some mods today to the thread. cheers!
I really like the way this thread is shaping up. :good:
Have you thought about adding something like a rescue / emergency tips section?
Something like:
To get out of boot loops do X.
If you are stuck on the splash screen do Y.
Always store a flashable recovery, stock ROM, and stock backup on your external sd card.
Etc, etc.

This would be good because bootloops and bricks normally aren't that bad at all on our devices. People think bricked their device and panic when its not hard to recover form that.
I've flashed hundreds of times in the past years and never had a soft brick or bootloop. *Looks for the closest piece of solid oak*
Agreed. Good stuff. I'll get started on an edit and have it up by this weekend. Thanks guys
Updated Post #2. Added lots of new material. Thanks to Hednik and Upndwn4par for the suggestions and again, many thanks to all those who have put in the effort behind all the information on this thread. I simply consolidate and share. Cheers!

Would it be worth adding something about moving between 4.1.X and 4.2.x roms? Regarding the changes to internal sd. I know as a rom flashing fiend I flip flop between the two pretty often.
Great post by the way, will be very helpful for new users!!

Hello,
I have thought about it and I want to try install CyanogenMod 12 on my LG G3 device, its an D855.
I wanted to ask how do I do that in the safest way, how do I backup everything and how do I install it from good place and if I want to go back to my stock ROM how do I do that.
I want to backup everything, pictures, music, music playlists, contacts, calendar, everything! The most of the are in my SD card, but I don't know actually how do I save playlists for example.
Furthermore, should I get CM 12? What do you think about it? why yes or why not?
Thank you!!

This type of question belongs in Q&A section.
First you want to start with rooting your device. To root it you could use:
http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
or find some other root method. Look for them here on xda LG G3 forum, or simply google it.
After rooting your device you want to flash TWRP recovery. To do that follow the instructions in this thread: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
After flashing TWRP either by adb or flashify, enter your recovery by powering off your phone and holding both power button and volume down button till you see LG logo, releasing them for 1 sec, then holding both of them again till you are offered to do a factory restart. Click yes if you did successfully flash your TWRP recovery. Your device wont be factory restarted, you will enter TWRP. You could also enter TWRP by using adb by typing: adb reboot recovery
After entering TWRP go to backup and do full backup of your storage(boot, system, data, modem, efs).
After finishing that go get your desired ROM. Pick one from here:
http://forum.xda-developers.com/lg-g3/development
Tastes are different, but I can reccomend you Blisspop, Resurrection ROM, etc.
It would be best if you try for yourself.
After downloading your zips, go back to TWRP and do a clean wipe. Wipe your system, data, cache and dalvik cache partitions.
Following that go back to TWRP home and install your ROM by pressing Install, then picking the zip with desired ROM and sliding up slider to flash. You will also want to flash Gapps. You get those from the same thread you found your ROM.
As for your music, photos, they wont be deleted as long as you only wipe your system, data, cache or dalvik cache.
For playlist, they will also stay, but I'm not sure you will be able to use them on new music player you get on your new ROM.
And finally callendar, contats can be backed up by synchronising them with your Google account.

Sorry about messing with the forums.
Thank you for your help, but I can't understand some things and I would like if you could explain me some of them.
What is the correct order of the things I should do to get CyanogenMod 12? Root first, next what? and after that?..
Someone gave me this guide, this is fine guide?
What do I wipe, how do I install the new ROM, where do I download the ROM? to my computer, to my phone, where do I save the zip files and how do I open them after in the installation? and do I know that the files are good?
This will wipe all my device and look like the day I bought him? with nothing in it? or it should keep my things?
And how do I get Play Store and Google applications after? and I still can use the Play Store right? with buying stuff from it?
And Im using PowerAMP for my music, so I should download it after installing the ROM and I think that the playlists will be there.
Thank you for helping!!!

You do in in the order I wrote.
Ok, step by step:
1.
Root device, use: http://forum.xda-developers.com/lg-g3/development/tool-dp-root-tool-to-root-lg-devices-t3075007
This is the direct link to the tool: https://www.androidfilehost.com/?fid=95916177934552571
Download it to your PC, of course install LG drivers to your PC before.
Enable USB debugging in Developer options on your device. To enable developer options go to about device, and click 7 times on build version. Connect your device to PC, run the tool mentioned above.
2.
Flash TWRP by using: http://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396
Direct link to the app: https://play.google.com/store/apps/details?id=b007.autorecd855
Download the app, install it, run it.
3.
Get your desired ROM.
You said its Cyanogenmod. Get it from that guide you found: http://lgg3root.com/t-mobile-g3-roms/android-5-1-1-root-for-lg-g3-cm12-1-rom/
Direct Link:
http://downloadandroidrom.com/file/LGG3/D855roms/CM12.1/cm-12.1-20150422-UNOFFICIAL-d855.zip
Download the ROM on your external or internal SD card.
To verify if ROM is valid use md5 checker, you have it built in in ES File Explorer (which you can download from Google Play) or find some other md5 check tool.
You have md5 value in the link I gave you above.
Also get your gapps from this thread.
Direct link: http://downloadandroidrom.com/file/gapps/5.1/gapps-L-4-21-15.zip
Save them on your internal or extrernal SD card.
4.
Flash the ROM and do a backup beforehand.
For this you need to enter the recovery we flashed in step 2.
You could do it in few ways. First one is to power off the device, then power it on by holding both power button and volume down button togeather, realeasing them for a second when you see LG logo, then holding them down togeather again till you are offered a choice to do a factory restart, click yes if you did successfully install your TWRP in step 2. Your device wont be wiped, you will enter the recovery.
Second way to enter your recovery is to use adb, enter adb, and write these:
su
adb reboot recovery
or use terminal emulator (dowload it from Google Play) and write:
su
reboot recovery
Thrid way would be to download some app from Google Play which will automaticlly reboot you to your recovery.
After you enter your recovery you will go to backup and do a backup of these: boot, system, data, efs, modem.
Following that you will fully wipe your device by doing this: go to TWRP home, click to wipe, advanced wipe, check these: system, data, cache, dalvik cache.
Finally you will go back to TWRP home, go to install, find your zip (Cyanogenmode, which you downloaded before) and slide to install it. Find your Gapps zip and install these as well. Gapps stand for Google Apps so you will be able to use Google Play and other Google Services.
You Finish with this. Reboot your device, wait for dalvik cache to build, have fun.
Your music, playlists will still stay on your internal SD card, they wont be deleted. You will also have a nandroid backup in case something goes badly. If that does happen, go enter TWRP again and restore it.
Hello friends
I had a problem with the mini z11, I have a hard brick.
I wonder if there is any recovery rom, or if the official serves me.
I can flash by nubia Toolstudio?
the terminal does not turn black screen on or enters recovery, flash a rom confusion mini z9.
I need help please, if you recognize the terminal QHUSB_BULK is hope.
Thank you for your interest, Greetings
Still a little bit early for Z11 Mini...
Did you unlock bootloader, rooted and installed some recovery?
Bricked device nubia z11 mini
Hi Guys,
I was looking to update the Nubia to v 2.04 from 1.40 so I used flashify to flash the stock recovery (worked earlier) but the system went dead.
I used tool studio to get the recovery back but now it is not reading my internal storage where the files are kept, it suggest mount error with system, data etc .... so what could be a way forward?

Follow this guide to flash twrp, use the vendor id from below guide
https://forum.xda-developers.com/android/development/recovery-unofficial-twrp-3-0-2-zte-t3550995
Then u flash the rom.
Before flashing the rom, wipe everything expect internal storage and sd card
Need persist.img
Hi,
Have got to know persist.img is corrupt. Hence, flashing is happening but no booting even twrp is not helping. Persist.img is usually found in fastboot img of the rom which helps to install rom in fastboot mode. Kindly do let me know if I can find fastboot.img of Nubia z11 mini.
Thank you
Hello guys,
i have the same brick mode as the op.
The system doesn't recognize the mobile, it only shows it as QHUSB_BULK and it keeps disconnecting.
What are the steps to follow from the pc?
I found somewhere one software called one click unbrick but when i try to install the drivers with it it says that "the system policy has been modified to reject unsigned drivers".
If i can take it to the place where the phone is recognized as a storage from the pc then i can take it from there.
Thanks
Unbrick and downgrade
I once brick my nubia the same way. BUT NOW ITS ALIVE AND WORKS FINE (sulking why didn't I bought the ZUK 2 even though at the time i bought z11mini they were similarly priced)
UNBRICKING:-
ALL you have to do is download the same firmware which was installed prior to the rom to which you downgraded to [ simply put if you had v2.40 running before and tried to install v1.40 then download the v2.40 rom for flashing), once downloaded {USE A PC OR MAC TO DOWNLOAD THE ROM OR ELSE IT MIGHT GET CORRUPT} copy it to the root of an sd card(2gb upto 32gb; sdxc cards may not work), insert the sd card into the phone , then press and hold the power button until the phone reboots, as soon as you see the bootlogo press and hold vol- and power keys simultaneously, you wold boot into nubia recovery now select update from sd card confirm and let it install as soon as update finishes your phone will boot back up normally. [UP TILL THIS POINT NO FILES WOULD BE LOST].
NOW YOUR PHONE WILL BE WORKING AGAIN.
DOWNGRADING:-
YOU DON'T NEED ANY EXTERNAL SOFTWARE FOR THIS
JUST DOWNLOAD THE ROM U WANT TO INSTALL AND PLACE INTO SD CARD AS ABOVE.
TAKE A BACKUP AND SAVE ON A PC, ANOTHER PHONE OR ANOTHER SD CARD{not the same one} OR ANYWHERE ELSE SAFE cause after this everything inside your phone will be DELETED.
BOOT INTO RECOVERY as STATED ABOVE.
-ATTENTION- DON'T install the rom as yet.
FIRST WIPE cache and data.
SECOND- INSTALL THE ROM SIMILARLY AS PRESCRIBED ABOVE.
THE SYSTEM WILL INSTALL AND REBOOT.
ENJOY{but why are you so eager to downgrade your system, i was once as well but after downgrade to lollipop.....nothing......performance was same as on Marshmallow.
ADVICE- for some reason the ota updater never shows any new updates, you will have to download updated roms from nubia website to install using recovery{the app has option to apply local update but it does nothing and gets stuck on nubia logo, u will have to restart your phone after that}, as long as you are installing updates u don't need to wipe data and cache and also your files will remain intact. BUT TO THIS ONLY EXCEPTION IS V2.06, on this you do not need to wipe data and cache but the rom itself will wipe all data on your phone so be careful. :good:

Hello --
I found this very nice looking phone thrown away in a bin and I guess this problem was the reason.
It would be great to get it going maybe even worth paying to get it running.
But I would appreciate any suggestions on how to do it myself.
I am not familiar with a lot of the in-depth hacks people do with phones. Words like "flash" and "ROM" are foreign to me.
But I like to try to fix things.
I have tried a few simple actions to get the phone going but it still does only three main things:
1. Shows the "Lenovo powered by Android" screen of course.
2. Volume down + Power: shows Fastboot screen with just three options: Start, Barcodes, Power off
3. Occasionally, some buttons I push get to Teamwin Recovery Project. But I do not exactly know how it happens and it is hard to repeat. It seems to come up after trying everything and then putting the phone down.
From TWRP I have selected these options:
-- Factory reset
-- Restore (I think) -- I selected just a single item displayed available for restore
-- Wiped Delvik cache and format cache
-- Reboot
I also downloaded ADB and installed it. Instructions I read said to run an .exe file but all I could find was .bat so I clicked on it and saw the RUN screen open briefly then close.
Thank you.

YOU CAN CHECK IN MY SIGNATURE FOR ALL BASIC TERMS USED IN FLASHING.
Look here if you want to return to offical stock Rom
https://forum.xda-developers.com/lenovo-p2/development/fastboot-files-stock-firmware-t3649914/amp/
If you have TWRP installed , you can update TWRP and then flash a custom rom. You can hold both volume up and down and power key to boot into TWRP when phone is switched off.
Remember new custom roms need newer version of TWRP.
What you'll need to do is download a custom rom like say Havoc OS Android 10 (just search it in the forum), you will need to upgrade your TWRP.
Once this is done, you will download Havoc OS Rom and put it in your phone or sd card
You just do a factory reset and then format only system . Don't format other partitions in TWRP.
Install that room and then you will also need to install gapps. (Google open gapps , chose Android 10 version and architect as 64bit and choose nano or pico gapps)
So in your sd card, you must have rom and gapps.
Once you install rom first and then gapps, restart. If it comes with an error, it means your TWRP needs update.
To update you will choose to download TWRP (zip format will install directly while IMG format can be flashed as well by choosing install IMG while you select install in your TWRP.
Restore is only available if you already made a backup with your TWRP .
I will suggest to make a full backup (except system and data ) in TWRP before you do the above.
I will also suggest you to Google if you are not sure. Make sure to follow instructions only from XDA as they are most reliable than other sources.
Watching YouTube videos may help you as well
In short:
Update TWRP
Download Havoc Rom and Gapps pico
Put them in your sd card
Install them in this order rom and then gapps.
Restart.
If you still feel you need help, please quote me for an answer
All the best .

Thank you for this advice -- it worked! Finally the phone gets past the logon and is operating.
Now I have a further problem and please let me know if you think this should be a new thread for this.
I cannot sign in to Google because of anti-theft feature -- instead I get this.
“This device was reset. To continue, sign in with a Google Account that was previously synced on this device”
I see a few solutions online but not exactly for Lenovo. What would you recommend?
I'm on the same boat as Nick. Do we have to wait 15 days to unlock the bootloader? Just coz it'll be hard to be 15 days without a phone and everything wiped out. I wanna try Syberia 2.9 as the last LineageOS is not ready yet. Thank you very much.

Now the phone seems to installaing the zip-file e-0.19-n-20211023142427-dev-i9305.
6, Reboot System.
7. After the system reboots it looks like the android is installing on the Samsung phone. However a letter e with a jumping dot below it is displayed and this goes for hours without any success of installation. I have waited 8 hours and nothing happens.
Is there something that I have missed to do?
Attached picture of the last step that I have reached in the installation process.
Please help.
Best regards

Hi!
Standard troubleshooting answers are:
1. You did not unlocked your phone's bootloader, enabled USB debuggind, USB debugging(security) and enabled OEM(bootloader) unlock in the phone's settings.
2. You did not flash vbmeta from your current ROM, to disable verity.
3. You did not flash a good bootloader before flashing.
4. Your SD card is corrupted.
5. You did not fix the File System from the recovery
6. You didn't allow modifications and left the recovery in read only mode.
7. The ROM is unsuitable for your phone. Sometimes this happens even if you were told it is for your ROM and it was written on some forum.
Hi
Following question, is it possible to troubleshoot these steps if there is not any android anymore installed and no backup file created?
Meaning that the phone only has access to the TWRP settings and all other phone data is deleted.
If all other data is deleted, please re-install an original ROM, This can normally be done from the manufacturers software, like a PC suite.
Before reinstalling the original ROM, please try flashing the bootloader with ADB and fastboot.
Downloaded it reinstalled and installed android 13 and it is working!
Thank You!
