[GUIDE] Flash/Install/Update to Gingerbread 2.3.4 to I9000: Detailed guide for n00bs

Disclaimer: I cannot guarantee that this process will work for you as it did for me. If something goes wrong I will do everything I can to help you, but you are responsible. This is a guide for the I9000 international version.
If you think your phone is "bricked" or something goes wrong then use this guide to get your phone sorted.
If you would prefer to use Heimdall to flash or you are not using windows then use this guide.
All "" in this guide are for emphasis or highlighting purposes. All commands should be typed excluding these.
Before you ask, if you have any questions about what PIT file you should use then see this and realise that it really makes little to no discernible difference.
What you need (All links are direct download):
Firmware you wish to flash. Generally find them here.
Odin3 v1.85 (Contained in the firmware)
USB Cable
Backups
Ability to get into download mode
>65% Battery
Section 1: Backups
1.1 Backups:
Download the above file now while you backup using:
SMS using "GO sms", "SMS backup and Restore" or "SMS Backup +"(syncs with Gmail).
Apps using "Listables" or other preferred app. Due to a glitch that occurs with most app backups, market links are not maintained on restore, meaning some updates won't work properly. Using listables you can create an XML list on the SD card and later reopen this list. Then simply long press on each item to download again from market, insuring that updates function correctly. Alternatively you can make a html list, email it to your computer and just reinstall everything using the web market, quicker and simpler. If this is not a huge issue for you then I recommend just using "App Backup and Restore".
Contacts using "GO contacts" or other preferred app.
APN using "APN Backup & Restore" (internal SD save, handles duplicates)
Call logs using "Call Logs Backup & Restore" (internal SD save)
[*}Bookmarks using "Backup Bookmarks"
These will all be saved onto the internal SD card which WON'T be wiped during the update process. If you wish to backup your SD card as well, then be my guest.
Section 2: Download Mode
2.1 Download Mode:
In order to install the new firmware, it is imperative that you can get your phone into download mode. To do this, hold the HOME button + the VOLUME DOWN button + the POWER button until this screen comes up:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If this button combination does not work then you probably need to install Android Debug Bridge (ADB) (See Appendix: Download Mode via ADB). If it does, go straight to section 3.
Section 3: Updating
3.1 Prepare Odin
At this point the phone should be in download mode, but have it unplugged from the computer. Extract the firmware and run Odin3, it should look like this:
In odin, there is a lot you don't really need to worry about. Just make sure that Re-Partition, Auto Reboot and F. Reset Time ARE ticked.
Click the button that says PIT, navigate to the folder you unzipped the firmware into, select the PIT file. Press the PDA button and select the CODE file. Press the PHONE button and select the MODEM file. Press the CSC button and select the CSC file.
Now (in download mode) plug in your phone. It may take some time for the phone to register with the computer and it may fail. If that's the case then see Appendix: USB Drivers.
Odin should now look like this with the yellow COM representing your phone connected.
3.2 Installing
Be extremely careful while Odin is flashing your device. Interrupting it is a surefire way to produce a $500 paperweight. I recommend holding your breathe and pretending you are a statue til it's done. Once your phone is connected properly and odin is prepared, hit install. This should take around 2-10 minutes depending on your computer etc. Once done, the phone should reboot and voila you now have gingerbread.
Section 4: Recovery
4.1 Start up
Once the phone starts up it should run you through the setup wizard. Go through this process and add gmail account etc. Then proceed to step 4.2.
4.2 Wipe Cache
Wiping the caches will remove any straggling data from previous installs. But don't stress this will only wipe data off the ROM partition area and not the SD card. While the flash has done most of this, sometimes things get left behind and this will clean them up.
Boot phone into recovery mode (Appendix: Recovery Mode)
You should no be in Clockwork Mod:
There are two options that we need to worry about "Wipe data/factory reset" and "Wipe cache partition".
You need to do both of these, in the order above.
Once these are done there should be an option to "Reboot system now". Do this.
Your cache should now be cleared.
4.3 Restoring
Open the market and download the same programs as before and use them to restore your data
Make sure that you turn off "Delete old messages" and notification settings in stock messaging app before restoring SMS.
Note that apps will not maintain a proper link with the market, it is recommended that you download all apps from scratch using the restore list as a reference.
4.3 APN Settings
If you backed up APN earlier then use the backup, alternatively:
Go to Menu --> Settings --> Wireless and Network --> Mobile Networks --. Access Point Names
Delete all present APN's via long press
Press Menu button --> New APN
Enter details appropriate to your provider which you should be able to find by searching for "<provider name> APN settings"
You may have to create more than one APN
Section 5: Extras
5.1 Rooting and Basic Kernel
Further modification usually requires a little something called root permissions. This is equivalent to administrator privileges in windows. While most custom kernels offer this, Chainfire's CF-Root kernel offers close to stock functionality with this feature added. Grab it here. The latest version should work for the firmware in this guide.
Put phone in download
Open odin
Plug phone in
Load kernel file as PDA
Install
This will install Clockwork Mod (CWM) as well. Having root permissions and CWM will help you modify your phone further (if you so desire).
5.2 SpeedMod Kernel
If you want to upgrade the phone just a tad more than download the latest version of Speedmod Kernel. It's a custom kernel that performs a little bit better than stock. To installs it, do the same procedure as above.
This will also install Clockwork Mod (CWM) Recovery.
5.3 Modem
To do this you need to have done step 5.1.
There are a heap of different modems you can use. The modem is basically the actual phone component of the phone that communicates with the network. Here is a list of available modems but not all of them are gingerbread compatible:
Modems
I would recommend downloading this one UGJL2 Modem. Good battery life and good reception. However, stock modems in gingerbread (JVP onwards) have comparable performance. This is only really something you should learn just in case it's more useful in the future.
You may have to adjust the modem to work on the right band. To do so see the end of the original post here: Modems
To install:
Download file
Copy it across to the phone SD card
Boot phone into recovery mode (see Appendix: Recovery Mode)
Navigate to install zip from SD card (see Appendix: CWM Navigation)
Find the zip you put there and select it
Choose Yes
Phone should install modem and reboot.
Appendix:
Recovery Mode:
Volume Up + Home + Power (until first galaxy s startup screen shows then release)
ADB (Appendix: Download Mode via ADB) "adb reboot recovery"
Download Mode:
Volume Down + Home + Power (until download mode screen shows)
ADB (Appendix: Download Mode via ADB) "adb reboot download"
CWM Navigation:
Use volume to go up and down
Power button to select an option
Back to go back
USB Drivers:
If your USB drivers aren't working then you can try reinstalling them with these:
32 Bit Systems
64 Bit Systems
2.2 Download Mode via ADB
To install ADB, download this and extract it to C:\SDK.
In My Computer, navigate to C:\SDK
In that folder there should be a folder labelled "android-sdk-windows", rename it to "SDK2"
In the second SDK2 folder, run "SDK Manager" and, after some time, this should show:
We only need to install the first one so for each item under the first one, click it and to the right click the reject button until your window looks like this:
Press Install
When finished it will ask to restart ADB, press yes.
Press Close
Once it has installed you need to run windows command prompt (press 'Windows key + R' then type "cmd" and hit enter)
Once in command prompt type "cd C:\SDK\SDK2\platform-tools"
Now type "adb reboot download"
You phone should now show this:
Download key combo should work after flashing.
Finished

Please let me know if i have missed anything.

Think this is the most detailed explanation online... Very Usefull... THANKS in the name of noobs...

ha, i see this thread AFTER i flash my phone (just flashed yesterday)

The perfect guide. I am almost tempted to Flash mine but I am still too much a coward.

wow this is just what i need.
My girlfriend has been complaining about how slow her stock 2.2 galaxy is going. She is finally going to let me mod it
Is there another download mirror i can get the 2.3.4 fw from instead of hotfile?
cheers.

You will find many firmwares here: http://forum.xda-developers.com/showthread.php?t=1102881 XXJVP is the first on the list and is only 147MB in size.

Thanks for the guide. There was some nervous moments when odin got stuck at factoryfs.rfs and my phone went green but I found http://forum.xda-developers.com/showthread.php?t=839556 and changed the USB port, and all went well.

Before you restore your previously saved precious SMS, make sure to disable the automatially delete older SMS messages because the limit is set to 200 SMS (same goes for MMS, limit of 20).
For SMS backup and restore, you may also use:
SMS Backup & Restore (internal SD save)
SMS Backup + (syncs with Gmail)
APN Backup:
APN Backup & Restore (internal SD save, handles duplicates)
Call Logs:
Call Logs Backup & Restore (internal SD save)
Bookmarks:
Backup Bookmarks
Applications, I did not find a solution that would "link" the apps back to the Market Place, so backing up downloaded apps did not make much sense, it did just speed up the restore. But if they are not linked and know to Market Place, the My Apps link does not do anything useful to me .
Cache clearing:
It is recommended to clear the cache as well after the firmware installation.

The guide says we don't have to tick repartition.
But i think it should, as it's a 3-file firmware.
And if you don't use repartition, there is no need to backup, cause you won't loose data.

Well since the Cache is recommended to be cleared after the flashing, it is recommended to backup. And I ticked the repartition, because I have seen this mentioned here: http://droidangel.blogspot.com/2011/06/guide-how-to-flash-updateupgrade_10.html
Better safe than sorry
Oh and don't forget to disable HSDP after the flashing in case you are fine with 3G UMTS internet speed: http://www.addictivetips.com/mobile...-for-better-battery-life-on-samsung-galaxy-s/

Easiest way for backing up SMS: the app called 'GO SMS'. Much better than the Samsung one. And there's a feature to back up SMS automatically.

You don't need to use a pit or re-partition with 1-file or 3-files firmwares, and there is no point in selecting a pit file while having 're-partition' un-checked.

True, regardless, I changed the guide to include PIT and re-partition. It's just a tad cleaner and some people get pedantic about that. Won't make a difference to those who don't.

I have seen the changes, you need to prepare your self now for questions like 'which pit file must I use ?'
I have also seen that you are using a link from samfirmware, why don't you use the link from Darky's Forum who was the source for this leaked firmware: http://www.darkyrom.com/community/index.php?threads/odin-cwm-base-ficetos-jvp-base-rom.3519/ samfirmware have just downloaded the firmware from Darky's Forum like everybody else and just put it on there forum.

[TUTORIAL] ClockWorkMod Recovery Navigation for Noobs

Hi
It just occurred to me that in all the instructions I've seen posted on using ClockWorkMod Recovery no-one has actually said how to navigate the menu system and when I was a noob it took me a little while to figure it out so I thought I would post here for others who may be experiencing the same.
Therefore I decided to write a tutorial on the subject.
===========================================================================================
First of all you need to get into ClockworkMod recovery. You do this by either pressing and holding the power button for 2 seconds and selecting recovery or press [vol +] + [vol -] + [home] + [power] together.
Once booted into ClockworkMod recovery this is what you see:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
You can navigate these options by using the Volume-Up and Volume-Down keys to highlight an option and the ‘Home’ key. Use the ‘Back’ key to go to the previous item.
Let’s review each of these options and their sub-menu options in detail.
reboot system now
This one is self-explanatory.
apply update from sdcard
This can be used for installation of any official or unofficial update, ROM, kernel, theme etc. that is in a zip format installable from recovery, as long as the file is named update.zip and it has been placed on the root of your SD card (i.e. not in any sub-folder). Selecting this option (and most of the options featured below) will bring up a rather annoying confirmation prompt but this will save you from a lot of trouble caused by accidental key presses!
This is what we are talking about:
wipe data/factory reset
This option wipes all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it or when any custom ROM was first installed. It will also wipe any sd-ext partition that you might have setup (more on this later).
wipe cache partition
Wipes the cache partition of the device to clear all the data accumulated there through use. This is often used before or after installing a new ROM, app, kernel or any similar mod via recovery.
install zip from sdcard
This option brings up the following sub-menu:
apply /sdcard/update.zip
This one is essentially the same as the ‘apply update from sdcard’ option of the main menu.
choose zip from sdcard
Lets you install any zip file (with any name) from any location on your SD card. The file can be for a ROM, a kernel, an application, a theme or any mod as long as it is in recovery-flashable zip format. Entering this option will bring up a screen that will allow you to browse your SD card for the zip file and select it for installation as in this screenshot:
toggle signature verification
Turns the signature verification on and off. When signature verification is on, you will not be able to install any custom ROMs that haven’t been signed by the developers (most custom ROMs aren’t signed). Switching it off skips the signature verification check and proceeds with the installation.
toggle script asserts
Simply turns script asserts on or off. If you don’t know what these are don’t change this option.
backup and restore
Undoubtedly one of the most important features provided by a custom recovery, the backup and restore feature – also known as Nandroid backup – allows you to take a snapshot of your phone’s entire internal memory including all partitions, and save it on the SD card. This what it looks like :
Backup
Takes a Nandroid backup, as explained above.
Restore
Lets you restore a previously taken backup. Entering this option presents you with a list of existing backups from the SD card that you can choose from for restoration.
Advanced Restore
This option is similar to the Restore option but once a backup has been selected to be restored, this option allows you to choose what parts of it to restore. You can choose to restore the boot, system, data, cache and sd-ext partitions, as shown here:
mounts and storage
Allows you to perform maintenance tasks on all the internal and external partitions of your android device
mount/unmount /system, /data, /cache, /sdcard or /sd-ext
These options let you toggle between mounting or unmounting these respective partitions. Most users don’t usually need to change these options.
format boot, system, data, cache, sdcard or sd-ext
These let you directly format any of these partitions. This should be used with extreme caution as formatting any of these partitions will result in losing all data on them, especially the boot and system partitions. Formatting the system partition will remove your ROM and leave your phone without an operating system while wiping the boot partition may brick your phone unless you restore or flash another one before rebooting your device.
mount USB storage
Lets you enable USB mass storage mode for your SD card right from recovery so that you can connect it to your computer via USB and transfer any files to/from it without having to leave recovery.
advanced
This section contains a few options most users will not require, although wiping Dalvik cache, for example, is usually required when flashing a new ROM. Here are the options from this section:
Reboot Recovery
Lets you directly reboot from recovery straight back into recovery. This is a useful option for certain back-to-back installations that require the device to at least boot once between them.
Wipe Dalvik Cache
Allows you to wipe the cache for the Dalvik virtual machine (the custom-built Java virtual machine for Android) as mentioned above
Wipe Battery Stats
Wipes the saved battery usage statistics and effectively recalibrates the battery - useful when your ‘phone isn’t showing correct battery levels.
Report Error
In case of errors, this feature can be used to save a log of recent ClockworkMod recovery operations on the SD card that you can later post in the forums if you have a problem.
Key Test
Lets you press any of the hardware keys to see if they are properly functioning, and to see their key codes.
Partition SD Card
This option provides an easy way to partition your SD card properly for use with ROMs that support data2ext (a very handy hack for low internal memory devices that enables an /sd-ext partition on the SD card to be used as the internal user data storage i.e. as the /data partition – see mizch’s post @ http://forum.xda-developers.com/showthread.php?t=999856&highlight=data2sd). Once this option is selected, you will be given options to choose the sizes for the /sd-ext partition as well as an optional /swap partition on the SD card, and will then automatically format it for you, leaving the remaining space for normal SD card usage. This option will wipe all data from your SD card so use it with caution!
Fix Permissions
Fixes the file permissions for the internal memory partitions back to default. This is very useful as a fix for several errors and Force Closes that start appearing after you or an application you installed and provided root access end up messing up the permissions of important files.
Hope this helps to save someone the same embarrassment I suffered trying to work things out

Basically once you have restarted your phone into CWM recovery mode you scroll through the menu options using the up/down volume keys, select menu options using the centre 'home' key and go back using the right 'back' key.

FAQ
¿Why now LG PC Suite no longer recognizes the phone?
This happens all the GT540, remember that the last official update was 2.1
But do not worry, you can replace the LG PC Suite by another program called MyPhoneExplorer. FJ Software Development
After install Android 2.3.7, I want rooting my phone, how can do you root for?
After installing Gingerbread is not necessary to do root, version comes rooted and superuser.
About Recovery Recovery
During the installation of Android also automatically install the recovery, so you need not do it again.

What do you mean, if you want the recovery version, look at the original thread in the developer forum. Also, this thread is pointless as 1. The main topic is in the developer forum 2. there are around 2 or 3 guides (including mine) that explain all of this anyway.

Wipe your data and re-flash. Where did you get the ROM from? Either get it from: Mur4ik's Twitter account or the 4pda thread (remember it's in Russian) as these are directly related to Mur4ik.

Yeahh! i do this tutorial, and i have in my GT540 the 2.3.5 version of android...
In the beggining i have had a lot of problems, but i solved all and now my phone runs perfectly
Thanks!

i think its easier to download from

its english and no waiting time and it belongs to mur4ik

I have a problem, I installed the fastboot and v20a, but I can not install 2.3.5 because it is simply a green dos window disappears in 1 second and finished, according to you what's wrong?

Do you have proper drivers instaled?

What to do you mean by that? You need to have command prompt set to the directory or the ROM along with the fastboot files.

How-to downgrade Impulse4g to froyo with 3g working

First:
- I am not responsible for any damage.
- This will change your IMEI.
- ***This will not work on Entel users in Chile as it is a locked restore (it is for at&t users only)-
- Just in case, do a Full Backup using this same method (but to your phone without the 3g working):
For Windows
For Linux
Now do an IMEI backup using the tool 5iromtoolbox (you can find it at the forum) (just in case also)
Now, lets restore to froyo with working 3g.
First, download the froyo backup file (about 400mb but its compressed, its really 3.9gb)
Here (thanks savagehq)
YOU HAVE TO DECOMPRESS THIS FILE AFTER YOU DOWNLOAD IT, OR YOU WILL BRICK YOUR PHONE!
The file that you need is a ".img" file.
Now you need the same tool that I posted at the beggining (for Windows) or you can use the Linux guide, also posted. (windows is easier).
1- Open the tool "Roadkil's Disk Image"
2- Enter to pink screen (volume up and down, then power on)
3- Connect your phone to the computer through the backside usb port (its more safe)
4- Run the tool
5- Click on the "Write Image" tab.
6- In "Write Image to" click the combobox and choose "Physical Disk #" ("#" is a number)
* If there are more than one "Physical Disk #", then you have to choose the one that is about 3.6gb.. This part is very important.. if you give us a backup from another disk, it will leave our phone unusable.
*To be sure that that Physical Disk you choose is the Huawei u8800-51, You can run the tool again (because it has to refresh) without the phone connected, then check which disks are available. Then, close the tool again, connect the device (in pink screen), run the tool, and check what physical disk was added. But it will be about 3.6gb.
7- In "source file", choose the file ".img" that you EXTRACTED FROM THE DOWNLOADED FILE (remember it is about 3.9gb and extension is ".img")
8- Press Write Image.
9- After it is 100% ready, disconnect and do a factory reset and you will have 3g working.
***This will not work on Entel users in Chile as it is a locked restore (it is for at&t users only)-

***FOR THE USERS ON WIN7 HAVING TROUBLE WITH ROADKIL ERROR***
Download LockDismount to fix the issue
1. Run LockDismount (Run compatibility XP3)
2. Select the necessary 3.69 drive described above (check multiple times to ensure you're selecting the right drive, for me it was Physical Drive 1)
3. Click Lock
4. Keep LockDismount open
5. Run Roadkil and then go through the downgrade process
Error should be fixed now!

Hopefully this works for me!

The camera isn't working for me, the camcorder is though. Anyone else have this problem?
EDIT: I notice everytime i uninstalled the default messaging app, the camera didn't work. I guess they're linked somehow.
EDIT 2: I looked further into it and it was the beats audio zip (can be found in themes and apps) that cause the faulty camera.

Will this work for normal U8800
My understanding is that Impulse 4g is U8800-51, which has hardware differences to regular U8800.
Will this work for regular U8800?
I flashed ICS Aurora, which nulled IMEI.
I can still get network service, but can't get wifi connection.

Look this ROM:
http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDU4Mzc=
Maybe this ROM can work in Chile
I download that ROM and test if work

Yeah, that should work for Impulse 4g and u8800-51 of course, and if you have nandroid backup of your original u8800-51, and you restore if after flashing this stock rom,it should leave your phone just like before.
BUT, I guess I am done with testing. My u8800-51 is now working great with this guide and horse rom for u8800pro. I dont want to test and risk that.

Awesome
Thank you so much for this incredibly useful guide!
Bricked my U8800-51 after attempting to update my stock rom with a version of CyanogenMod customized for the U8800. My phone has been returned back to normal thanks to this guide.

My girlfriend, in her haste, flashed 2.3.5 to her Impulse 4G, not realizing she has a U8800-51 and not a U8800.
In my attempt to get her phone's data running again I flashed ClockWorkMod successfully and the Aurura 4.1 ROM successfully, but still no data.
Booting the phone by holding VOL UP + DOWN + POWER gives me a pink screen, but doesn't show up as a drive under Windows 7 or Linux.
Is it because I flashed CWN onto it? Is there anyway I can get it to show up as a drive so I can use the 3.9GB restore image?

[HOW-TO]Android 8.1 for Z00VD/ZC500TG

Hello people of XDA,
as I promised here, here's a tutorial for getting Android Oreo 8.1 up and running to your device.
NOTE: I DID NOT MAKE THIS TUTORIAL! This is a translated guide from 4PDA by nik-kst. I've also rehosted some of the files on Google Drive so you won't have to register on 4PDA(hopefully).
Code:
[B]Your warranty is now void. [/B]
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
Now that the disclaimer is dealt with, let's get on with this tutorial shall we?
First things first, we need to grab a bunch of things:
SP Flash Tool;
MediaTek VCOM Drivers;
The Stock Kernel(it will make sense to you soon!);
Scatter file for repartitioning, drop it inside the stock kernel folder(credit to fca.sjc);
ADB and Fastboot of your choice;
New recovery;
Oreo's Backup, drop it inside a MicroSD card or drop it once you have re-partitioned the device successfully;
Once you have everything setup and extracted, you're ready to go!
First, we gotta go ahead and install VCOM drivers - we won't be able to do anything to our phone without them.
If you're running Windows 8/10, make sure to disable Driver Signature Verification.
Go to Device Manager, click Action at the top and click Add legacy hardware. A new wizard window will appear.
Choose Install the hardware that I manually select from a list(Advanced);
In the next window, choose Show all devices and click Next, then click Have disk...
Then you will be prompted to direct to the driver install info, so click Browse...
Now go to the folder of drivers and select the Setup Information file that's fitting for your computer, x86 for 32-bit and x64 for 64-bit.
You should now find 5 new devices in the list, add them one by one by repeating steps 2 to 6 until you have all of them installed.
Windows might complain about unsigned drivers, just allow their installation and proceed.
If your ports list looks similar to the picture below, then you're set for the next step!
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Next, we'll want to back up the NVRAM partition, because AFAIK, it keeps important unique data about your device such as WiFi, IMEI etc. data.
Note: You may want to take out your MicroSD card and SIM cards prior to this just in case. Also, might be the possible fix if readback for NVRAM fails(needs confirmation).
First, open up Flashtool.exe as admin and go to Readback tab;
Click on Add, a new item in the list will appear. You want to double-click on it, so that a Save File window would appear.
Save that file anywhere you want, name it whatever you like, for convenience I've named mine ROM_NVRAM.
Now, you'll want to find the address in the memory for NVRAM partition. To do this, open up the stock firmware(credit to fca.sjc) scatter file in a text editor(like Notepad++), and find line partition_name: nvram
In that paragraph, find two values: linear_start_addr and partition_size they should be 0x380000 and 0x500000 respectively.
Punch in those values into the Readback block start address window, so it should look something like this:
Now, click Read Back, it should gray out along with Add and Remove.
Now, turn off your device, pull out the battery for about 30 seconds, reinsert it and DO NOT TURN IT ON YET! With the Volume Down "-" button pressed, plug in your device into the USB port.
The NVRAM partition should've been read and you'll get a giant green tick sign when it's done.
Now that that's done, we can start repartitioning our device.
Make sure your SP FlashTool is running as admin, otherwise restart it as admin.
Open up the Download tab and in the line Scatter-loading File click Choose and navigate to the 8.1 scatter file, it should be named MT6580_Android_scatter_8.1.txt.
From the dropdown list, select Format All + Download.
Again, take out the battery for 30 seconds and put it back in WITHOUT turning it back on.
Now click Download, and with the Volume down "-" button held down, plug the device into your PC. There should be a bunch of colored progress bars at the bottom of the window.
Once it's done, you should get the giant tick pop-up, after which you can disconnect the device, and start it normally.
NOTE: it takes a while for the first launch, so give it some time!
Once it starts up into the first launch wizard, we can now restore the NVRAM.
In order to activate the memory writing function of SP FlashTool, re-start it with admin and press Ctrl + Alt + V, the window header should have (Advanced mode) now.
From the Window drop-down, select Write Memory, it should redirect you to a new tab named accordingly.
In the File Path field, browse to the ROM_NVRAM backup that you made earlier.
In the Begin Address (HEX) field, copy the linear_start_addr value off the scatter file.
The region should be left at EMMC_USER.
Now, click the Write memory button, turn off the device, re-insert the battery just like before, and connect the device with the Volume Down "-" button pressed.
It should begin the writing of the NVRAM and once it's done a giant tick pop-up will appear.
Now after that is done, boot into the OS, check that everything works, including IMEI and WiFi.
Also, during the setup wizard or later in the settings setup a screen lock with a pattern or a PIN or a password(credit to fca.sjc), because the partitions may remain encrypted and show 0mb(needs confirmation)
Now you'll want to unlock the bootloader and flash the TWRP recovery.
Now this is a standard recovery flash, but for a quick summary:
Enable Developer options;
Enable OEM unlocking;
Reboot into bootloader mode(I like to use ADB for adb reboot-bootloader);
Make sure your device is detected via fastboot devices, if not, google some drivers for ADB;
Unlock the bootloader via fastboot oem unlock, and press the Volume up button to confirm the bootloader unlocking.
Now, reboot the phone, it will take a while to reboot, DO NOT PANIC AND WAIT.
Now that we have bootloader unlocked, we can flash the TWRP:
Go into bootloader mode;
Confirm you are being detected again by fastboot devices;
Flash the recovery with fastboot flash recovery [twrp recovery name].img;
now, WITHOUT booting into system we boot into recovery and confirm it works.
Now that you've done all this, you propably want to run Oreo now, eh? Well, here's what we do now:
Note: make sure you have the Oreo's backup zip extracted at it's own folder inside your MicroSD card or inside the phone's internal storage by now(thanks @ZappaDong for letting me know)
From recovery, select Wipe > Advanced Wipe and select system and vendor, and wipe them. Logs may complain about not seeing vendor, ignore that message.
Then, we restore everything from the Oreo backup;
Finally, do a factory reset(aka wipe Data, Dalvik and cache);
And reboot!
Now, fingers crossed, you should be booting into a fully functional 8.1 Oreo! if you did, congratulations!
Please let me know if I've made any mistakes and/or this has worked for you.

Reserved for possible FAQ in the future

@aurismat, Hey man it worked as expected ! However, I was a bit confused on the repartitioning part when selecting ''Format all+download'' option then clicking ''start'' will only give an error stating that the IMG file of ''vendor'' is missing. (I am using SP FLASH v5.1744)
But nevertheless, I tried the ''Download only'' option and lucky it worked as well. I just wanted to clarify should it be Format all +download or Download only? Or is there a missing corresponding IMG file for vendor ?

Hey @JustAnormalGuy,
It should've been Format All + Download.
Also I'm glad that my post has helped at least one person.
Thanks for pointing out this omitted detail though, I'll edit the post ASAP.

Thanks for the translation!
--- solved ---
I have tried it three times but never managed to back up the NVRAM partition.
Error: s_dl-get_fram_setting_fail (5054) see attached screenshot
-----------
I have used Win 10 on my Mac and it worked.
Now I am stuck at step "5. Unlock the bootloader via fastboot oem unlock, and press the Volume up button to confirm the bootloader unlocking."
this looks O.K. to me
----------------------------------

and nothing happens.
UPDATE
O.K. I have used the Power Button to switch it off and on again, there was a small Android for a few seconds and the phone rebooted the second time. Now I am waiting for it to finish booting.
UPDATE 2
TWRP is working now
And what TWRP.img should I use for
"3. Flash the recovery with fastboot flash recovery [twrp recovery name].img;"
in the next paragraph? Is this the "New recovery;" from the download section at the top?
Thank you!

Missing tips:
- Put both scatter files inside the stock kernel folder before starting.
-I used the stock scatter file for the NVRAM backup then the 8.1 scatter only for the Formal all+Download step.
- When you first run the stock ROM, set up a pin or a password, otherwise you will have failed to mount data in twrp and data will show as 0mb due to its encryption.

@aurismat does that WW file includes the new vendor release?
In the vendor, a bug was detected, the camera with the auto flash turned on, did not turn on (rather, it turned on and off immediately), the flash when shooting video.
Now everything works as it should: yes2:
Fixed vendor: 07/07/2018
https://yadi.sk/d/DUGRYLnc3YtADV

I did everything according with this tutorial. Sadly my mobile network is not connecting idk why. I get an error saying Simprocessor and it doesnt connect on mobile network. It detects the networks but wont connect. Im going back to stock until someone can help me fix it.

@ZappaDong:
Yes, you should use the one I provided the link at the list of downloads.
Also, a bit late and I may be wrong, but your DRAM reads may be hindered by a MicroSD card(confirmation needed). Try ejecting it before you read off the NVRAM.
@fca.sjc:
First of all, thanks for pointing out my missing tips.
I'm not really sure if it includes the fixed vendor. I didn't really have any issues with the camera's flash, so they already included it(?)(again, needs confirmation).
For failed connections, make sure you flashed the NVRAM correctly(hence why you should test the telephony after you've repartitioned to stock 5.0 with the NVRAM backup flashed).If you failed to do that, I was told you should be able to recover the NVRAM data with Maui(?) software(confirmation needed, once again).
Thanks to both of you for pointing out these tips, I'll update the guide and credit you when I'll have more time. Cheers!

[*]For failed connections, make sure you flashed the NVRAM correctly(hence why you should test the telephony after you've repartitioned to stock 5.0 with the NVRAM backup flashed).If you failed to do that, I was told you should be able to recover the NVRAM data with Maui(?) software(confirmation needed, once again).

After repartition, wifi, 3g and mobile signal works fine. I just cant flash twrp after unlocking bootloader otherwise i get a bootloop (unable to mount data and storage). So after i installed twrp and wiped/restore vendor and system, i reflashed stock recovery to acess android and then, restarted again to recovery. At this point, i did the write memory step again, using old vendor and the new vendor. None seem to work. I even backed up NVRAM using TWRP at first to make sure i did it right and tried to restore from there and it doesnt seem to be an IMEI issue. Maybe it has something to do with the frequency. Im on Brazil right now and idk
It does recognize my Sim card, my number, it downloads the data operators and etc but it doesnt connect to the mobile signal idk why. The bug starts at the restore step so it has something to do with this part.
I just test stuff but im pretty experienced at flashing and reflashing, etc. I guess only a dev can help and i actually went back to 7.1 UHANS rom, wich i got from 4pda.ru. Before using this rom, I was having a bluetooth audio stream bug and Ive tested like 4-5 roms, one for each kernel that was there. Lets see if someone can help me with this, cause i want oreo for better bluetooth audio stream.
Thanks for your help so far. I really apreciate it. This device is very good and we dont see many mods here on xda for it.

Thanks again!
I am using Windows 10 (bootcamp on the iMac) now and I have read the description in the 'old' [ROOT/TWRP] thread but used the files you have provided.
TWRP is working now, but I got an error that the ZIP file on the SD card was corrupted. Maybe I have damaged it when copying it to the SD card under OS X.
I am just redownloading it with Windows 10 and give it another try. (Yandex is very slow now, about 60 KB/s)
------------------------------------------------------------------
UPDATE
I have downloaded "WW_Phone-user_810_O11019_1528478718_release.zip" again, put in on the SD card, booted into Recovery, wiped system and vendor and chose "Install" , selected the "WW_Phone-user_810_O11019_1528478718_release.zip" file.
But I still get an error message.
Installing zip file '/external_SD/WW ... release.zip'

Yup that one

@ZappaDong, yeah I kind of forgot to mention again - you should've extracted the .zip in which the backup came in. It's a backup, not an installation zip.
It needs to be extracted into its own folder inside the MicroSD card, so that then it could be used by TWRP to recover the partitions.
Thanks for pointing this out to me though, gonna edit it ASAP.

@fca.sjc bro AFAIK that problem of yours could be because of one or more of the following:
1. Your IMEI is missing or null. I would suggest SN Write tool (since I already tried it). Is quite effective, it is comparable to Maui Meta although I haven't tried it yet. (Tutorial here ==> https://forum.hovatek.com/thread-12306.html )
It is better to use PC restore tools since it writes directly to the nvram unlike apks like Chamelephon which (according to what I know) writes only to nvdata.
2. You need to switch the sims. What i mean is just if you have 2 sims on your phone, switch sim 1 in with sim 2. I forgot the explanation on it but it helps.
3. You need to switch off data connection on the other sim. On the several roms I tried on 4pda including this 8.1 pixel based rom, upon first bootup, the data connection on both sims are already on, therefore 3G cannot work. So first turn both sim's connection off then check if network mode is set to 3G. If not do the Solution #2.

It is the best IMEI restore tool since it writes directly to the nvram. (Meaning it retains even after wipes to data, system etc. via twrp)
2. You need to switch the sims. What i mean is just if you have 2 sims on your phone, switch sim 1 with sim 2. I forgot the logic on how that helps but I've seen it as a solution as the phone rereads the sims.
3. You need to switch off data connection on the other sim. On the several roms I tried on 4pda including this 8.1 pixel based rom, upon first bootup, the data connection on both sims are already on, therefore 3G cannot work. So first turn both sim's connection off then check if network mode is set to 3G. If not do the Solution #2.

Thanks for your help bro. I did check the IMEI while i was on this oreo rom. It seem to be ok. Number was there but i did not check if it was the right number. I might check it when i try to flash again. Probably later today when i'm home.
The problem wasnt just data connection, it was the connection itself. I couldnt call or receive SMS to activate whatsapp, for example. Like i said previously, those features were ok after repartitioning (on stock repartitioned). After the restore step, i did check all network options, including data, network mode, network connections available,etc. I'll follow your tutorial to restore the IMEI if the numbers are different then. I'll remember to take some screenshots next time so you guys can help me figure out what the problem is. Thanks again

@ZappaDongIt's a backup, not an installation zip.

Yes, that did the trick. The installation went through and everything seems to work now.
Thank you again for your patience.

I saw there in the forum 4pda that are doing roms project treble pro zenfone go, only that I can not understand the mode of installation, you know how?

Yeah, it is possible -
FIrstly you'd need a vendor image that has fixed RIL(telephony) - vendor off this thread's 8.1 has RIL broken in Treble ROMs.
Luckily you can get it off any 8.1 custom ROM off ska-vova in 4pda. Just download any of his .zips(i.e. his ResurrectionRemix ROM(which imo is just official ResRemix with their Russian preference for a browser, but fine)), flash them and then backup the /vendor off it(and /boot for good measure)
Buuuuut then you need a TWRP that supports system image flashing - not sure if the one I provided here has it, if it hasn't - I'll post it here.
Then all you need to do is flash the Treble image, restore the /vendor(and /boot if you need to) and hope for the best!
Sadly the Havoc OS 2.0, the only ARM A-Only Pie-based ROM available here didn't work for me - just straight bootloops.
Your mileage may vary - if you get the Havoc OS 2.0 instaled, I'd love to read about it.

Can you do a tutorial? I did not quite understand how it installs. Sorry, google translate does not help.
