To EddyOS for the Tutorial on getting the PB99IMG from the RUU
I didnt find any newbie friendly guides for unrooting the HTC Desire, on XDA. Even some external ones arent that easy to follow, unless you have a very good idea about what is going on.
The main purpose of this post is to benefit people who have got an SLCD bricked device on their hands with nothing displayed except a blank screen, and cannot remember the key sequences necessary to activate the unrooting process, or to run the OTA Update and get to Android recovery. You will note that I have added the time taken at each step in the process. This will benefit people with SLCD bricks waiting anxiously without seeing anything on screen.
For a complete guide on Unbricking an HTC Desire, please see my thread here.
There are two methods of unrooting an HTC Desire.
Methods:
Get the latest RUU for your region from Shipped Roms. This is an exe file. You can run this file directly from PC. Then connect your device when so prompted.
The second method is to flash the rom.zip directly from the Android bootloader interface, after renaming the Rom.zip (which is actually obtained from the RUU) to PB99IMG.zip [See EddyOS's excellent step-by-step guide for dummies, in the FAQ below]
Method1 does not need any explanation (If necessary, I will add illustrations of this process later along with error codes)
Method2 is illustrated below.
Note: The following post illustrates the actual steps necessary to unroot your HTC Desire by running the PB99IMG.zip. This is also the method to upgrade the software with the RUU, the last method to fix bootloops cause by a bad boot, and also the way to unbrick an SLCD bricked Desire. Note that another simple method exists to unroot the device, and that is by directly running the exe file of the RUU from Windows. Though simple, this is slightly riskier, since complications with Windows drivers, or a sudden power surge or PC reboot can semibrick/brick your device. The following method using PB99IMG.zip eliminates those problems.
Unrooting is just one of the steps necessary to unbrick an SLCD bricked HTC Desire. The process is a pain for these users because they cant see anything on the screen and left pressing keys in sequence, whose function they can only guess. Also they need to wait specific amounts of time before pressing the sequences.
I'm making visible the steps which the Android system proceeds through, when you run a PB99IMG.zip to unroot your Android device. I've also included the time taken before each step while running the WWE 2.29 RUU as PB99IMG.zip. The time isnt much different for other ROMs. To be sure, just give it about 30secs more than the time I've noted.
Initial steps:
Create a goldcard if you want to convert a branded Desire to unbranded, or vice versa, or to make a Desire of one region (CID) accept software written for a phone of another region.
After creating the goldcard, format it as FAT32. If more than one partition exist, delete the rest, and format one as Primary and FAT32.
Put the file PB99IMG.zip into the root of the goldcard. Note that the name must be PB99IMG.zip and not PB99IMG.zip.zip. Windows has a tendency to rename it as the latter.
If you dont already have the PB99IMG.zip, you can get it by running the RUU, and while the RUU is loaded (dont start the RUU upgrade. Just click on the exe, and when the welcome screen of RUU shows up,) search in your Temp folder for the file rom.zip. Hint: To quickly navigate to Temp, Type the following into the Run window: %TEMP% [If you still get this step confused, see EddyOS's excellent tutorial on this, in the FAQ below]
To run the PB99IMG.zip, just reboot with Vol- and power button pressed.
I'm describing the whole boot process below for Reference, though.
Hboot mode (Vol- & Power key. Key them pressed for a 5-6 secs
FOR INSTALLING ANY RUU AS PB99IMG.ZIP
Press Vol- , then w/o releasing it, press Power button + Vol –
After 3-4 secs, the following screen shows up momentarily:
· Fastboot
· Recovery
· Clear Storage
· Simlock
This shows the above few options for 2-3 seconds, and then directly checks for PB99IMG.ZIP. It displays:
SD Checking…
Loading…
PB99DIAG.ZIP
Pb99DIAG.nbh
PB99IMG.ZIP
When it finds PB99IMG.zip, it starts to load it (13 secs after you press the Vol- & power key)
It gives the next options after 2min 20seconds (for the WWE 2.29 RUU) from the initial key press of Vol- and Power key.
Parsing………………….[SD zip]
1. Bootloader
2. Radio V2
3. Radio_Cust
4. Boot
5. Recovery
6. System
7. Userdata
8. Splash1
9. Splash2
Do you want to update device?
<Vol Up> Yes
<Vol Down> No
So, net key sequences involved:
· Back+Power
· Power again
· Vol Up
If we chose No, next option:
Do you want to reboot device?
<Vol Up> Yes
<Vol Down> No
If you pressed Yes, then:
Update is in progress..
Do not power off your device.
1. Bootloader -OK
2. Radio V2 -OK
3. Radio_Cust -OK
4. Boot -OK
5. Recovery-Unzipping/Updating
6. System
7. Userdata
8. Splash1
9. Splash2
It cycles through each of these in turn. For me, it took exactly 2 min 17 secs for time when I chose to apply update, to when update was completed.
(Note: At times, it may update the bootloader and reboot. If you have an SLCD screen, when the device reboots, you may not see anything onscreen (black). At this point, it is notable that the device boots to Fastboot instead of Bootloader, so you will need to press Power button again to get it to resume the update process. Once it completes, you will be presented the options to reboot the device. So you just need to Press Vol + after some time)
It displays:
Update complete
So you want to reboot device?
<Vol Up> Yes
<Vol Down> No
Congratulations. Your phone is now officially unrooted.
On rebooting, HTC screen shows up for a few seconds.
Then a green Down arrow in a green circle shows up for another 5-6 seconds.
Then, HTC screen again.
Finally, HTC screen disappears and the HTC Quietly brilliant logo shows.
Your device now boots into the Android phone.
Total time taken: 6min 30 seconds.
If the Rom is incompatible with your SLCD device, at the reboot stage, you will hear the momentary vibration. Then after about 10-20secs, you will hear the HTC Quietly Brilliant tone. The phone will boot, and the keys light up after about a min, indicating that the Android system has booted up. Since the Rom is incompatible, there's still nothing on screen. To shutdown the booted up phone, press power key, then swipe your finger vertically up-down like you do to unlock your phone normally, which is exactly what you're doing. Then keep Power button pressed until the phone vibrates. This means it is presenting you with the Power menu. At this point press the trackball once, then once more. The phone will now shutdown. At this point you can flash your SLCD compatible update.zip (OTA) and unbrick it.
FASTBOOT mode
Back+Power key:
4 options:
· Bootloader (For running PB99IMG.zip)->Choose with Power key (This loads the Bootloader/Hboot mode)
· Reboot
· Reboot bootloader
· Power down
Bootloader (Hboot mode) or PB99IMG update mode.
Performs the following check on the PB99IMG.zip:
1. Bootloader
2. Radio V2
3. Radio_Cust
4. Boot
5. Recovery
6. System
7. Userdata
8. Splash1
9. Splash2
Do you want to start update?
Vol Up: Yes
Vol Down: No
So, net key sequences involved:
· Back+Power
· Power again
· Vol Up
If we chose No, next option:
Do you want to reboot device?
<Vol Up> Yes
<Vol Down> No
No brings up the following options:
· Fastboot
· Recovery
· Clear Storage
· Simlock

Frequently Asked Questions (FAQs) for Newbies
Frequently Asked Questions (FAQs) for Newbies
1. Why do I need to Unroot?
To take the device to service centre for warranty
To fix problems with Boot and Recovery unsolved by other methods
2. What are the methods of unrooting? Which is safer?
Basically both methods are the same. It is the process of flashing an original HTC software onto your ROM. One method involves running an .exe file from Windows, and the other is by running a file extracted from this exe file from the sdcard. The latter method is called the PB99IMG.zip method, because it involves renaming the rom file so extracted as PB99IMG.zip. This method is generally safer because the whole process can be completed from your phone itself. The method of running the exe is prone to corruption because of problems with Windows drivers, your Usb cable, Battery issues, and even a Windows System Failure or System Crash or Power Failure!
3. How do I get a PB99IMG.zip? [EddyOs's complete tutorial for Dummies]
(The illustrations and answer to this question has been provided by EddyOS)
If you still get lost, dont even bother to ask!!
1. Double-click on the RUU file and wait until you get to the first main screen
2. Move the window to the bottom of your screen because it can’t be minimised and will sit on top of all other windows
3. 3. Click on Start>Run and type ‘%temp%’. Then click ‘OK’
4. Look for the newest folder in the temp folder. Double-click on it
5.Copy the file called ‘rom’ to your Desktop
6. Rename the file called ‘rom’ to ‘PB99IMG’
7. Copy this file to the root of your SD card (root = not in any folders)
4. Do I need a Goldcard?
If you have a recent version of the RUU for your Device, available on Shipped Roms, you dont need a goldcard. This is the usual scenario for people who purchased their Desire in Europe, and so have an unbranded Desire. All Branded Desires need a correct branded version of the RUU, and any other RUU including WWE (Worldwide English, or European) RUU will not work for them. Also if an unbranded Desire user wishes to change RUU to a branded version, he will need a Goldcard. This is because all Desires have a particular software tag in the Rom, called the InfoCID. This dictates the Region code. For Eg. An Indian Desire is branded and has InfoCID of HTC__038. When you change a RUU to different region, what you actually do is reset the InfoCID setting. Changing the InfoCID setting requires a Goldcard.
5. What is a Goldcard?
It is a normal MicroUSB card specially prepared in such a way that its Sector 0 (which normally doesnt hold anything useful) is modified, so that it signals to the HTC RUU that the InfoCID may be changed.
6. How do I create a Goldcard?
Just download this tool (Credits and All Rights by [email protected]), and run it.
In case your card in phone cannot be detected by the PC, download and install Goldcard Helper from the market and use it to generate the Reverse CID
7. Can you tell me more about Goldcards?
Sure. I've already posted it for you. Read the FAQs in this thread.
8. I think I've bricked my Desire. I cant unroot it with your method. What can I do?
Follow my thread on Unbricking a Bricked Desire. Though it's written for SLCD device, it will work for AMOLED too. The chance of success depends on two essentials: 1-That you have a working goldcard, and 2-You have a compatible RUU (of version higher or equal to the current version)

Hi,
Thanks for informative article. Can I install PB99IMG.zip using the standard clockworkmod @ recovery mode?
Edited: I tried using windows, it failed. I tried the 2nd method, but Desire does not reconize the PB99IMG.zip file and so nothing happens.

When you mean you tried it in Windows, do you mean you connected the cable and ran the exe file? If so, what error did it give you?
You cant flash it via Clockwork. And you dont have to.
Assuming you have only one partition on your sdcard and it is formatted correctly as FAT32 and the PB99IMG.zip is placed in the root folder, and you press Vol- & Power button to start your Desire, it will detect the file and start the update process. Problems usually happen when the card is not formatted correctly, and the file is named PB99IMG.zip.zip and not just PB99IMG.zip. This is because Windows may not display the full filename including the zip extension.

one simple question
i wanted to root my phone so i could flash to a custom ROM, but i have since updated to 2.13.707.2 OTA, but i cant seem to find the RUU in shipped ROMs site...
could i use the 2.13.707.1 RUU to unroot?

Hi droidzone,
Thanks for the quick response. The error I got from windows 7 pro was (translated from German):
error 170: USB connection failure. The update software was not able to connect to mobile. Make sure the cable is connected to both PC and mobile.
My SD card is partitioned into FAT32 and a small parition ext3 for apps. This configuration is defacto for DeFrost, OpenDesire, and Oxygen ROMs. I moved the rom.zip file and renamed it using rootExprorer application to be 100% sure. When I go to recovery mode and then to Clockwork I can see the exact file name and its correct PB99IMG.zip (I am not sure if the system is case sensitive) but PB99IMG.zip is the exact name. Of course I restarted win7 few times but nothing changed. I need this because my mic is bricked like described in this thread

It's worth a try.Normally an older version cant be used on top of a newer version. It will give a "main version is newer" error. A newer version will always work. If it still doesnt work for you, downgrading may be the only resort. Get Teppic's downgrade tool for that.

Could be a Windows driver issue. The PB99IMG.zip method should work for you though. Remove the ext partition, and partition the whole card as one big FAT32 partn, format it once, and then put the file there again. It should work.
If it still wont work, use another sdcard, repeat these steps.

FYI, I used another SDcard with only FTA32 partition and it worked. Howerver it did not fix the mic problem. Thanks!

Good..If even a new RUU installation didnt work, I'm guessing Hardware issues. Maybe a good time to get it checked.

I have a debranded Desire on 2.2, accidentally updated with an OTA yetserday without goldcard and have now lost wifi.

You have a debranded Desire, you said.
Well then, the PB99IMG of the latest RUU should work for you.
Just flash it as I've described from Hboot.
Put the goldcard in just for safety, and do it.
Should work.

Hi Droid
Thanks for quick reply.
Can I just confirm a few bits . . .
Goldcard leaves 3 folders on SD ( android_secure, footprints,lost.dir)
Then copy and rename the RRU to PB99IMG and copy to SD.
Reboot to HBOOT and then get previous messages :-(

To be safe, do the foll verbatim:
Delete any additional partitions on goldcard (if any). The goldcard should have one big FAT32 partition
Format it as FAT32 once again with original allocation size
Transfer the PB99IMG.zip that I have linked in my post to the root.
Check the filename and be sure that it is not PB99IMG.zip.zip
Reboot in Hboot by Pressing the Vol- & Power key
The file will be detected and presented with menus
Follow the instructions in the OP

I'm guessing I don't need a goldcard with my unbranded desire?? But screwed if it does. Also what is the unbranded ruu currently as there is literally hundreds? Thanks
Sent from my HTC Desire

BTW, what does it mean WWE rom?

WWE - World Wide English
To others, if you've flashed the OTA without your gold card do it again manually WITH your gold card and you're good to go. Flashing a full RUU is only need if you can't fix it manually

#2 after u unlock bootloader u will still have s-on but ur device is now rootable...
#3 root ur device using unlockroot one click tool (www.unlockroot.com) and u will have root access superuser installed..congrats u r now rooted
#4 installing clockworkmod recovery on your phone via fastboot method (plz dont use rom manager to install cwm recovery as it just provides a temp recovery)..just do it via fastboot method (scan xda forum on how to do it via fastboot)....done ...u r ready to flash a custom rom...
#5 download any custom rom for wildfire (ex:cyanogenmod 7.1.0.1 buzz)and place it on sd card...turn off ur phone and reboot into bootloader and select recover,,ur device will now boot into recovery..then select install zip from sd option and choose the rom file...congrats ull now boot into a custom rom...(dont forget to backup ur existing rom )..hope it does the job for u....

[Guide] Return stock without latest RUU

Who should read this post?
You have updated your One X to a newer version via OTA, then you want to restore the software/ return stock but the latest RUU is not available. (boot to fastboot mode and type the following command "fastboot getvar version-main", This is the true version of your phone!)
You have some basic skills to flash things using "fastboot"
Those who want to back to stock and wait for the JB OTA.
Those with ICS hboot should works without any problem, someone had test it on JB hboot and works(updated in step 6, 7). but we need more testers.
The concept behind.
1. Fool the RUU to make it believe that it is flashing the latest ROM, but actually, we are flashing an older version.
2. after that, boot up the phone with older version of software, then OTA and update the phone to latest software.
How to do that?
0. backup all your stuff including those in SD, all your stuff in your phone will be lost. Then wipe all data (including SD) using your custom recovery. (important! Otherwise, you may not be able to receive OTA).
1. You have to download a "custom RUU" that can be found here.
http://db.tt/z8ajRTuH
Feel free to give a thanks to billd2439, he provide this working link to download the custom RUU.
Just go to #115 http://forum.xda-developers.com/showthread.php?p=35139501#post35139501 and give him a thanks
2. Download the ROM file, it should be in zip format. (You can also extract the rom file by running a RUU, just run the RUU, don't click anything and search the computer for "rom.zip") (In my case, I have an older version 1.29.708.15 rom extracted from RUU)
you may want to find RUU here http://www.htcruu.com
3. unzip the customRUU.zip to a folder, e.g. "customRUU"
4. unzip and extract "android-info.txt", "boot_signed.img" and "system.img" to a folder
5. open android-info.txt with "notepad" (notepad++ is highly recommended)
6. type the following command to get the information from your phone.
fastboot getvar all
you should pay attention to the following information
modelid:
cidnum:
mainver:
hbootpreupdate:
7. edit the value of "modelid", "cidnum", "mainver" and "hbootpreupdate" to match the information you get from step 6.
by doing this your will try to fool the RUU to belive that you are going to flash a newer version e.g (I have OTA my phone to 2.17.708.7, but now I want to fool the RUU with this old rom with a version number of 1.29.708.15, so I change the value to 2.17.708.7 )
Thanks ahmedaljaf for telling me to modify hbootpreupdate to makes JB downgrade works
8. save the file.
9. zip "android-info.txt", "boot_signed.img" and "system.img" and rename the zip to "rom.zip". (remember only zip the files, not the whole folder!)
10. place the "rom.zip" you just created to the "customRUU" folder
11. make sure your phone is still "unlock", remember to turn on USB Debugging, unplug the USB cable and reboot your phone, then goto fastboot mode and connect the USB cable.
(important, do the above to avoid error messages in RUU)
12. run the file "ARUWizard.exe" inside the folder "customRUU" (see the Attached Readme_Eng.pdf if the customRUU cannot display in correct language)
You can change the customRUU to English version by just delete or rename the language file "ARUWizard_Eng.lng" (Thanks ahmedaljaf for telling me this :good
13. follow the on screen instruction,
14. your phone should reboot and boot up with and old version of software.
15. restart the phone and go to fastboot mode.
16. extract the "recovery_signed.img" from your old "rom.zip" (not the rom.zip you create! ) and place it to some where.
17. flash the recovery by typing the following command "fastboot flash recovery recover_signed.img"
18. relock the phone
19. boot up the phone and try OTA
18. if the OTA download finish but fail to reboot to recovery update automatically, just manually boot to recovery and the update will be ok.
If you can return stock with this method, please reply and list the version here. And you can give me a "thanks" :good:

I wonder, if you put in the "rom.zip" the "hboot_0.95.0000.img" from an older RUU will you be able to downgrade the 1.28 hboot also?

There's NO way to downgrade hboot unless you have s-off.

They are somebody on chinese forum who use this method claimed he was able to do hboot downgrade through this method, but no one seem suceed so for.
Well, technically this method able to get you spoof ROM version because it check on your PC. While for hboot it validate the signature and version on the phone before upgrading itself. You can see the process if you push the firmware yourself via fastboot.

What if we hex edit the 0.95.0000 before we put it into the rom.zip to make it think that it's a newer version, will that brake the signature?
Sorry but I don't have the guts to try it myself

a good link

Who should read this post?
You have updated your One X to a newer version via OTA, then you want to restore the software/ return stock but the latest RUU is not available.
You have some basic skills to flash things using "fastboot"
Those who want to back to stock and wait for the JB OTA.
The concept behind.
1. Fool the RUU to make it believe that it is flashing the latest ROM, but actually, we are flashing an older version.
2. after that, boot up the phone with older version of software, then OTA and update the phone to latest software.
How to do that?
0. backup all your stuff including those in SD, all your stuff in your phone will be lost.
1. You have to download a "custom RUU" that can be found here (you can also found a rom that for One X for HK only).
http://pan.baidu.com/share/link?shareid=64762&uk=1042525484
If your phone is from other region, you may want to find the rom or RUU here http://www.htcruu.com
2. Download the ROM file, it should be in zip format. (You can also extract the rom file by running a RUU, just run the RUU, don't click anything and search the computer for "rom.zip") (In my case, I have an older version 1.29.708.15 rom extracted from RUU)

4. unzip and extract "android-info.txt", "boot_signed.img" and "system.img" to a folder
5. open android-info.txt with "notepad" (notepad++ is highly recommended)
6. edit the value of"cidnum" to match your phone, e.g. ("HTC__622" for HK, "HTC__621" for Taiwan)
7. edit the value of "mainver" to the current software version your phone. e.g (I have OTA my phone to 2.17.708.7, but now I want to fool the RUU with this old rom with a version number of 1.29.708.15, so I change the value to 2.17.708.7 )
8. save the file.
9. zip "android-info.txt", "boot_signed.img" and "system.img" and rename the zip to "rom.zip". (remember only zip the files, not the whole folder!)
10. place the "rom.zip" you just created to the "customRUU" folder
11. make sure your phone is still "unlock"
12. run the file "ARUWizard.exe" inside the folder "customRUU"

or you could just cook yourself a flashable zip from the rom.zip. Then fastboot flash rec and boot. Chances are ics wont boot on the newer hboots. Still the ota can be flashed as update.zip maybe.

usefull for some case

BRILLIANT! Absolutely brilliant! Thanks a million hokoonho. This method worked like a treat on my HK_621 HOX which was running ARHD 9.7.2

The method works well with ICS, even with other HTC model as well, but I am not sure if it still work will JB and latest hboot. But it won't kill your phone.

I have followed the instructions, and now I am at the point where I run "ARUWizard" and follow the onscreen instructions...
However, The test is not English, it is funny looking as if the language is corrupt/unrecognised.

Any advice?

It's OK, The RUU may not be able to select the right language to display, but It still works, since the RUU only use adb and fastboot to finish its process, and all these adb and fastboot are run in English...
A brief translation was made for those cannot Open the customRUU in correct language. go to OP for the pdf file

No problem, I have found an English version.
I am finding that I get a Error 170 USB error... I believe this is because I have an unlocked bootloader.
So I re-locked the bootloader... and found myself unable to get past the bootloader.
I managed to run the RUU whilst phone was at the bootloader screen,
Replaced the temp rom.img with the created rom.img in your guide,
But it ended up failing with a Error 132 signature check.
I am not sure how to proceed.

Don't relock at this moment, otherwise, you will not be able to flash the stock recovery. Unlock it first. Make sure USB debugging is on, then REBOOT to fastboot and start the RUU. Or...Try another USB cable, DON'T connect via a USB hub...

Hi there, let's go step by step without "shortcuts" that are typically working on PC/WIn.
1. Unlock bootloader of your phone at HTCdev[dot]com [replace 'dot' with . - sorry for confusion I haven't earned reputation to post external links yet]. All necessary tools (fastboot) will be provided to download during process as well as necessary instructions. You need Windows/Linux or OS X computer to complete this step.
2. Download custom recovery .img file and save it to same directory you have fastboot files (e.g. from step 1) on you computer
3. Start phone in fastboot mode (mind fast boot option in Power settings must be unchecked if you using VolDown [-] start option (not necessary if you use adb reboot bootloader). Battery must be charged over 10% (I suggest 30% to stay secure); connect to computer (phone shall display Fastboot USB)
4. Navigate command/terminal window on your computer to location of recovery image file from step 2 (fastboot files must be there or have a correct path specified).
5. On computer terminal window run command: fastboot flash recovery filename_of_recovery.img . Red section must be exact custom recovery file name.
6. You'll get some communication in terminal. If completed OK will be among them, if failure, there will be FAIL with description of reason (e.g. low_power). If only "waitng for device" dislays, check connection with phone.
7. Navigate phone to HBOOT, then select recovery. If recovery don't start, check step 1 and restart from step 3. If only icon with red ! appears, it means you have stock recovery installed. Please verify from step 1.
8. Once custom recovery is installed and working, use it to flash SuperSU or any other superuser app (must be flashable .zip to be applied). Install just 1 root application, to avoid problems. At this point, you may consider flashing busybox also if you plan extensive file modification, but it's not necessary for root. For any sake, clear cache befor restart.
9. Restart the phone - you shall view SuperSU application or any other superuses app you've flashed i step 8.
Hope now works.

Thanks for your answer, I have to say I properly unlocked the phone so I do not think there is a way I messed up with this step as when I start bootloader it clearly shows on the top of the screen ''UNLOCKED".
When I flashed recovery on my phone I had no errors prompted or any message of failure. The process went well until a success notification.
Now when I start my phone into bootloader I repeat, I clearly see that recovery has been installed but when I attempt to start it then I'll be almost instantly brought back to the bootloader screen... now I started to wonder if... if an update of android could cause this kind of issue? The point is my phone is using android 4.4.4 and not the factory version 4.4.2. I remember having updated my android version which was perhaps a mistake as this phone is not very old and I was planning to root it in the next days... Now I'm not expert just try to figure it out.
I tried different system to auto root via different apps, some using the PC some using directly the phone, I never get any success...

Guide to check and change fingerprint from CN to WW with final Android 9 1910.64 RAW

FIrst off many thanks to @vhercastillojr (as this thread is essentially his) and Chicken from the Vietnam telegram group for providing the RAW's/img's
********** DO THIS AT YOUR OWN RISK!!! I am not liable to any damage if you accidentally brick your device. This will void your warranty, if you had one. Also, using this method you won't be able to revert back to CN roms, lock your bootloader again and recieve OTAs, your device will be blacklisted by Asus ************
NOTE: To check your current fingerprint, download and install device info HW from the playstore. Under 'system' you'll find the current rom (CN or WW), the product id and fingerprint - they all need to match to be able to update your device later
NOTE 2: The main guide below skips early roms straight to last Android 9 for ROG II. For one user it didn't work and they had to use the previous, unedited guide which was based on 1910.35 RAW. If the below guide fails to update follow the additional guide at the end of this post.
----------
0) Download the ROG phone unlock tool and copy it on your phone and install it then run it. The phone will boot twice. DO NOT PRESS POWER TO STOP THE BOOT. It will wipe your data automatically. This will unlock your bootloader. EDIT: NEWER VERSION OF THE TOOL CAN BE FOUND here
NOTE: this will void your warranty, if you had one, with Asus, even if you re-lock your bootloader later... (Although, having bought mine as an import from China, I'm think the warranty only stands with the seller - in my case, 1 year, not Asus - but i may be wrong)
1) Download the WW International RAW rom from here
2) Extract the file on your PC. Boot the phone into fastboot mode (hold volume up then press and hold power button, Fastboot mode is the 1st screen you come across, the one with the options to Start, boot to recovery, etc...) connect to the side port and run "flashall_AFT.cmd" wait for it to finish and the phone will restart itself (it will take a number of minutes to complete, with the cmd window open all the time. If the cmd window only flashes up and closes down, then check the rest of the notes with this step).
NOTE: you need to remove or delete the original zip from the raw folder once extracted as it confuses the Flashall_AFT.cmd with the raw rom and zip having the same name. Also, it can help to extract to the root of C drive.
3) Download and install Minimal ADB and Fastboot app (windows). Install it on your PC to root of C drive
4) Download the rootww191064.img and place it in the Minimal ADB and Fastboot Folder (C:\Program Files (x86)\Minimal ADB and Fastboot) from here
5) Run Minimal ADB and Fastboot by double clicking ''cmd-here.exe''. Switch the phone into fastboot mode (hold volume up then press and hold power button) then type "fastboot flash boot rootww191064.img" without quotation marks
NOTE: you can also check your device is recognised in fastboot mode by the pc/laptop by running ''fastboot devices'' cmd which should show your device serial
6) Reboot the phone and connect it to PC, copy and install Magisk and Root Explorer
Magisk
root explorer
-run magisk, (update if necessary) and grant access to root explorer (after opening root explorer you should be prompted by magisk to gain root access, click 'allow')
7) Open the Root Explorer App on you phone. Then from the app, select Mount R/W to R/O. Search for "/vendor/factory" folder and Edit the file content COUNTRY from CN to WW (ALL Capital). Scroll to "/system/etc/AsusTheme/themes" then delete the hidden file to enable the hidden themes.
8) Restart the Phone. You are done. Check again with device info HW that your fingerprint has indeed been successfully changed.
From here, if you want to be on latest Android 10, download version 2004.60 from here (full zip), place it in root of internal storage and reboot. That'll bring you to A10.
NOTE: For those of you that are rooted: Download the full zip, move to root of internal storage and reboot. System will detect and prompt to update, click update. Wait until it finishes but DON'T click 'restart', instead, click 'restart later'. Go to Magisk manager. Click 'install' for Magisk. Click the last option 'install to inactive slot after OTA'. Click confirm force flash. Reboot when prompted. Done - root kept intact.
Repeat the process for latest (currently 2012.65) using the same link above. Your phone should hopefully skip the other versions and be straight to latest. If not, you'll have to go through 2007.27, 2009.49 and finally to current latest 2012.65. Repeat the process mentioned above for keeping root if so desired
----------
For anyone still running early roms that 1910.64 won't flash directly to, use the same guide above but with the following corrections:
2) Follow the exact same instructions but using this 1910.35 RAW
4) Download root and stock boot img's and extract them to Minimal ADB and Fastboot Folder (C:\Program Files (x86)\Minimal ADB and Fastboot)
5) Run Minimal ADB and Fastboot by double clicking ''cmd-here.exe''. Switch the phone into fastboot mode (hold volume up then press and hold power button) then type "fastboot flash boot rootww191035.img" without quotation marks
NOTE: you can also check your device is recognised in fastboot mode by the pc/laptop by running ''fastboot devices'' cmd which should show your device serial
After doing the ammended steps above for 1910.35, follow the rest of the guide to change fingerprint, then update to 1910.64 zip, place it in root of internal storage and reboot.
NOTE: For those of you that are rooted: Download the full zip, move to root of internal storage and reboot. System will detect and prompt to update, click update. Wait until it finishes but DON'T click 'restart', instead, click 'restart later'. Go to Magisk manager. Click 'install' for Magisk. Click the last option 'install to inactive slot after OTA'. Click confirm force flash. Reboot when prompted. Done - root kept intact.

Which rom version are running, if it's already 1910.35 then you can skip the flashing rom part. But if it's different, you need to follow each step

Edit; didn't realise you were at this stage... Are you sure the flashing of the raw rom worked OK? Did you a cmd window open for a good 5-10 mins while the rom flashed?

Will KingRoot app work to root this phone? Don't want to have to wipe data to root.
I am pretty sure it won't, but humor me. Or is their something else out there that works?

One moment, I'll check the links... And yes, that is the only unlock tool available from asus website...
EDIT: yes, the zip file to download in step 4 needs to be extracted. it contains both the root boot img and stock img for later on when you unroot etc (both root and stock boot img's are for 1910.35). you need to place the rootww191035.img in the same folder as adb... and do the same for the stock boot.img for later use... read the instructions carefully...

in step 4) you download a .zip file that conatins BOTH rootww191035.img AND boot.img - the boot.img IS the stock boot for unrooting 1910.35, you need to extract both img's to adb folder on your pc.

What you downloaded is not, I think, the raw rom, its the update zip for those who have already changed fingerprint and are simply updating... Please use the links in 1st page...
