[Q] Asus TF600T Not showing update 8.1 even after tutorials.

Hello!
I own a Asus VivoTab TF600T and have Windows RT 8.1 Preview installed from a few months back.
Now I try to find a way to get the official 8.1 update but can't really get it to work.
What I did is using the Modern UI to find updates, no luck.
Then I tried the windows classic UI Windows Updates, activating "Search for other product drivers". No luck here aswel.
I also tried to find the update KB 2871389, but doesn't appear in my Installed Updates list, and the device has no more updates to install.
I did the "run/wsreset.exe" and that did not show any results.
I need to have this update in order to get the tablet back in Italian, as I sold it to an Italian friend.
Thanks!
PS: I asked the same question on the Windows Forum, but I really never see any good answers on there, so I ask the awesome XDA members who are WAY better then "wana b MS devs"

I had the exact same issue:
Follow the directions from the following link under the section marked
"I installed the preview from the Windows Store or I installed the preview using media while Windows 8 was running"
http://windows.microsoft.com/en-us/w...e-from-preview

Windows 8.1 Phone

Since windows 8.1 for phones is able to flash into any android devices would it be possible to flash WP 8.1 on the LG G3?
Let the games begin. Still remember the HTC HD2 "The Legend" a phone that was capable of amazing things because of amazing people.

They can ?? How link? I have a Lumia with 8.1

Hey,
ASUS has made a full Android 4.2.2 version for the vivo tab rt available. Unfortunately there isn't a way to flash it onto the tablet because of secure boot etc. I've seen someone mentioning that an older uefi version was hackable.
So maybe if you put the old uefi version somehow back on there, you might be able to boot that android version.

I wish people didn't post stuff they can'i back up. If you don't know the answer don't post. Does anyone know if it can be done?

Microsoft Secure Boot Golden Key is online, is this the start of a new life for the VivoTab RT? :

Maybe someone will port it over.
The Android version of the VivoTab RT TF600T is ASUS Transformer Pad TF502T. On the Asus website the Kernel Code for Android 4.2.1 can still be found (http://www.asus.com/support/Download/28/1/0/17/32/).

Any update?

Has someone found the ASUS Transformer Pad TF502T Android rom? It would be very possible to dual boot Android and Windows with this device.

Hi everyone, any update on this subject ? Would be very interested in replacing Windows by an android ROM
Thanks for your ideas on the matter !

My friend has managed to install a ROM.. will get the update for you all.

Hi i`ve just recently bought a Nokia Lumia 1020 from china..
And joined windows 10 insider fast ring, i`ve had no problems upadating this phone from windows 8.1 to the latest
offering from microsoft, but for the life of me i cannot downgrade back to win 8.1
I`ve read all the tutorials i`ve done numerous soft & hard resets tryed different usb cables tryed different ports unistalled and reinstalled
WRT..
Now here is the thing that i don`t get,
When i connect my phone to my PC running win 7 WRT recognises my phone and then proceeds to tell me that there isn't
anything available on the server..
So i have held the volume button down & power pressed in, and restarted WRT to find my phone which it does and then proceeds to download a new rom.
But the new rom is for a different phone.. this is the rom downloaded by WRT
RM877 3051 50009 1451 1 RETAIL nam att 205 01 473928 prd signed.ffu
My installed rom is RM-875-apac_hong_kong_223

first of all : why downgrade? have problem with w10?

Thanks for your response, there is a issue with the camera not working. I had no problems with this until i upgraded to win 10
This is the main reason for me buying this phone because of the camera,

yes of course 1020 has great camera
but im not sure every people with 1020 who upgrade to W10M have this problem...
what is your problem?
do u try Lumia camera beta?

For some reason that app is not showing on windows store for me

Try That
Lumia Camera Beta https://www.microsoft.com/store/apps/9wzdncrfjbm0

Intersting, my phone is just in the process of updating the windows store, i`ll check when it`s finnished to see if it shows
Thank you kwanice i`ll keep you informed..
Still does not answer the question why i`m struggling to down grade back to win8.1 though & why the server is downloading a different
file i.e mines 875 and yet the downloaded file is 877, or is it compatable, and why does my phone reject the install?

Well updated windows store, and searched again for lumia camera beta, and it`s not showing anything

Thanks I`ve also posted this problem on microsofts windows 10 insider forum, but no one seems to have any answers for this problem
Just my luck!
Might just trade in this phone and get a android phone with a decent camera....

Help needed to install Windows 10 for ARM32 for Nokia Lumia 2520 RT

Hi guys, can anyone help to install Windows 10 for ARM32 for Nokia Lumia 2520 RT tablet?

Same procedure as other devices but you will have to substitute the drivers with ones from the 2520 aside from qcpep which has to be replaced with an alternative one which I think came from the Lumina WoA project staff (From Lumia 930?). However, if your 2520 has been kept up to date with the latest patches under RT 8.1 then you won't be able to jailbreak it in order to use 15035

Hi JWA4 could you expand on this? Also is it the case for the surface RT as well (latest up to date version can't be jailbreaked) or just the 2520?

The short version as I understand it is that Nvidia screwed up in users favor which makes the Tegra Surfaces immune to permanent effects of the jailbreak killing Windows RT updates. On these devices reversing the negative effects of theses updates is as simple as a factory reset.
Sadly with the Lumia 2520, Qualcomm did the job right and at present there is no going back if a jailbreak killer has ever been installed.
I will try to find the detailed explanation I read and post it here asap.

I was unable to find the explanation that I read but if I find it again I will post.
I could be wrong and there might be more to it but I think the general idea was that Nvida did not implement the mechanism that handles the revocation of previously issued certificates correctly whereas Qualcomm did. On a previously updated Lumia 2520 this prevents the Secure Boot Debug Policy from working because its certificate is no longer going to be valid on the device.

How were you able to do this? I thought the Secure Boot issue stopped any other installations?

Go to Discord. I discuss all the sub-genes there. The system is not ready for public use. Testsign, secureboot and everything you need is there. No problem using Linux via grub uefi. It is much more difficult to find developers who will do this. And Tales about the impossibility of disabling Secureboot is just a fact of bygone days. The device is now free of these restrictions.
No touch, no modem, no BT, no audio, adreno 330 not work.
But yesterday qcpep and qcpepproxy did not work as expected.
Today they are working as expected.
I will start other hardware devices too. It just takes time.

i need help to install windows 10 rt on Nokia 2520

I know this device is so outdated and all, yet it'd be nice to get some use out of it. Anyone have a proper guide on how to accomplish what @CageOff was saying in order to bypass the security update patches and getting securebooot unlocked. I've tried so many different methods and gotten nowhere in my attempts to get working BOOTABLE USB media for 8.1. No guide clearly explains/points out that the Myriachan's Jailbreak is the exploit specifically intended for the Qualcomm Nokia Lumia 2520 to get the test mode exploit going (if it works). Longhorn obviously doesn't work as it can't install Golden Keys. I went to the Telegram group @CageOff mentions, but there is no way to talk to the person nor any clear info about how he managed to dualboot win10 arm/win8.1 arm. If anyone could shed some light on me here, It'd be much appreciated.

Myriachan is not specifically intended for Qualcomm devices, its just that it can't be permanently patched against but this won't help you for 15035.
I don't have a 2520 but from what I can tell CageOff seems to have booted 15035 on a 2520 but the details are getting lost in translation and a writeup doesn't seem to be forthcoming. From what I can gather even though he has booted 15035 on his 2520, he has done so without the installation of the QCPEP driver and without this driver virtually nothing else will work.
On QCEP - BetaWiki.net
This build does not support the Nokia Lumia 2520 Qualcomm Power Engine Plugin driver. Loading a newer driver for the Snapdragon 800 is mandatory.

The newer driver I believe is harvested from the LumiaWOA project, specifically taken from the Lumia 930 package. It could be worth looking at how WFAv7_Installer installs 15035 on a 930? It might shed some light on the driver ordering, as far as I've been told Qualcomm stuff has to be dealt with in a certain order.
Before you put too much time in to this though remember 15035 is about as much use a chocolate teapot so remember its just for fun. If you spend a week figuring it and actually get it all working in the hope of making an ex-RT device useful you are going to be a little disappointed at the end of it.

That's definitely worth looking into in regards to the "WFAv7_Installer". I just tried the WOA Deployer v2.7.1 and it seems it could be of great use in getting Win 10/11 arm onto this device. Of course, if one can figure out how to access/enter a Mass Storage mode first.
I also read in another forum article that the IOT versions of Windows seems to be more useful for this device, rather than trying to get the standard Pro/Home editions. They also mentioned that one may need to apply the drivers from the original Win 8.1 RT in order to get all of the devices hardware working though. I would personally like to give this a try, but I can't seem to get to the point of being able to install Win 10 build 15035 onto my device. I can't enable test-signing mode, nor disable bootloader with any of the jail breaks available. I get the error code 0x000000000000d (not sure i put the correct amount of zero's there), which seems to give no existing info on the net for that error code, only a few forum posts regarding the variant to that code which ends in "f" which seems to be related to the Surface 1/2 devices.
I know I can format the eMMC properly via command prompt, diskpart, and dism (for Win 8.1 RT), then disable BitLocker (even though C:\ still says Bitlocker Encrypted). Yet, I just can't get the Win 10 media to work which i assume is due to secure boot. Does it make any difference if I'm using the install.wim or install.esd versions of the media?

WOA Deployer is specifically for deploying WoA on the Lumia 950 & 950 XL, it doesn't support Windows 10 15035 or ARM32 devices like the Lumia 2520.
Windows 11 is out of the question, only small parts of it were built for ARM32 (nothing close to a full client) and the bits that were built won't work with this SoC. I don't believe WFAv7_Installer ever had the 2520 in mind, I only suggested it because how it prepares an image for some of the Lumia phones might shed some light on how an image would need to be prepared for the 2520.

That's going to come down to what you define as useful but personally I don't see any point in running IoT on a tablet. At the time of writing only the 15035 client build is available and that's now over five years old. Drivers taken from the RT 8.1 recovery image would be required along with the replacement PEP driver mentioned previously but its possible not all drivers will be compatible with IoT.

To enable test mode you would need either Golden Keys or the Myriachan jailbreak, unless you are lucky then the device you have might not be capable of using Golden Keys anymore. If I'm remembering correctly the Myriachan jailbreak is only useful for running third party applications under RT 8.1 and wouldn't assist in running another OS.

Windows 10 15035 isn't available as an ESD, you would need to take the 15035 installation files and properly add the drivers to boot.wim, install.wim and winre.wim before copying them to USB and attempting the installation. CageOff seems to have installed 15035 without the use of Golden Keys but even when booted the installation of 15035 is useless because he has not added the PEP driver.
