Guest Garsay Posted April 22, 2019 Report Share Posted April 22, 2019 1 hour ago, dazmatic said: That would explain why the image I got from the known working Hudl had only got 32 bit efi file, no 64. To which I then flashed a 64bit UEFI which is searching for 64 bit efi and OS. Me being an idiot didn't backup the original 32bit UEFI flash and then flashed with 64. Probably would have gotten away with it if I had kept a backup. Silly really as I've backed up everything so far, just thought they were the same. EDIT: Yep, checked build.prop on newer Hudl, was running 4.4.2. Damn, need a UEFI bin from a 4.4.2 Hudl. Can you please try this BIOS to boot Windows? Because I made a pretty important adjustment and it could work. Much please TAB Tesco Hudl 2 - Win.zip Link to comment Share on other sites More sharing options...
Guest dazmatic Posted April 22, 2019 Report Share Posted April 22, 2019 I'll try that. Got nothing to loose at the minute! Seeing as your looking into bios's, I've extracted the below from what I believe to be an android 32bit efi. IT's a bios update but in a .fv format, not a .bin so I can't flash it! Can you see if you can convert it to a .bin? Thanks BIOSUPDATE.zip Link to comment Share on other sites More sharing options...

Guest dazmatic Posted April 22, 2019 Report Share Posted April 22, 2019 Well, I put the 32bit 'BIOSUPDATE.fv' efi file extracted from the hudl2_ota_rel.android-build.20150529.110309_to_rel.android-build.20150803.092218.zip file into the EFI folder on the emmc and now it won't even boot at all from any source so it's clear to me that's not going to work. Will have to reflash the uefi again. Link to comment Share on other sites More sharing options...

It is a pity that it does not want a boot, I do not understand what is there for other problems, but the BIOS is ready for Windows 8, I will not give up, I found HDMI switching, so I solder the cables to SPI and try to flash if I can HDMI as default. Otherwise, with the BIOS flash update, I didn't find anything about x86 / x64. Link to comment Share on other sites More sharing options...

Can't even boot a windows 8 image though now which is strange. Windows or Linux on the other would be great as I could probably use it as a sole display for a laser engraver Edited April 22, 2019 by dazmatic Link to comment Share on other sites More sharing options...
Guest dazmatic Posted April 23, 2019 Report Share Posted April 23, 2019 Can boot android x86 to install but it won't boot thereafter so whatever you've done to the uefi file has not been for the better it seems. Will flash back Link to comment Share on other sites More sharing options...

Will flash back It should be better for Windows, not for Android, but good that you wrote it, I'll keep trying. I soldered SPI flash to CH341 again, so I can try it with myself. It is interesting that I can not activate HDMI as the default display, but according to the settings it should go, if it does not solve, so I can not try anything and the display in the Czech Republic can not get.

Guest dazmatic Posted April 23, 2019 Report Share Posted April 23, 2019 Yeah, that's what I was hoping for. With previous uefi I could boot android x86 fine so something isn't quite right. Link to comment Share on other sites More sharing options...

Guest dazmatic Posted April 23, 2019 Report Share Posted April 23, 2019 Can't I'm afraid, my original uefi dump was done at a time when I had the crappy FT2232H board and the dump is garble. There is a link below however that I've found with a bios that someone from a previous post on this thread linked to which is an original bios and it compares well but no indication whether it's 32 or 64bit. I've not tried flashing it yet but what the hell, I might try on my 4.4.2 tablet. https://sites.google.com/site/unferium/x86-store-area/HUDL2-BIOS-copy1.BIN Link to comment Share on other sites More sharing options...

As I can see, my ROM is not kicked, but what I considered to be bugs are log records. I just don't understand why enchce it to HDMI, it's possible that it wants to turn off fastboot, or turn on the UEFI setup option to run after a system restart with a command. But it is too much for me, I do not have so much time to do it, hopefully I will get to it Link to comment Share on other sites More sharing options...

Guest dazmatic Posted April 26, 2019 Report Share Posted April 26, 2019 So it turns out that needing to solder/reprogram the bios each team isn't needed. Been speaking over at the win-raid forums and was made aware it's possible to change the bios variables from a special EFI grub https://www.win-raid.com/t4638f16-Request-UEFI-Bios-mod-request-to-unlock-menu-s-for-tablet-bios-Hudl.html So far I've managed to disable the fast boot and enabled text mode but still can't get into the bios menu.

Hi, I'm sorry I haven't heard from you for a long time, I'm very busy. 1. I use the UEFITool tool to explore UEFI and HxD for editing in Hexadecimal. 2. Your Pogo pin programmer is very useful. I also thought about something like that, but unfortunately I don't have the equipment and the time. 3. Your request is good, it would be useful if someone tried it. I've found everything like switching Windows / Android, HDMI / eDP / Auto (I needed it), and besides SecureBoot I found OS Indication, where you can switch to UEFI Setup from the system by command. Perhaps I will find time for the weekend and something will happen to me. Even so I am glad that I am not alone and that you are also interested in it Link to comment Share on other sites More sharing options...

I'm also interested in booting Ubuntu and alternative android versions, but don't have a spare to test on, only the one that i use most days, so i'm waiting for a tried and tested process first Hi If you want, I have a bootloader with an unlocked SecureBoot that can run with the original android, but with Ubuntu. On Ubuntu, I started running WiFi and Bluetooth, but they didn't work before, but the touch that doesn't work, so as dazmatic wrote, I probably won't work because I don't have a display module. I'm trying to make Windows (8.1 / 10), we have a problem with ACPI resulting from UEFI settings. I even know which variables to change, I gave it a lot of hours, but I'm still without good results. I do it for the first time, but I believe that it will happen to some of us Link to comment Share on other sites More sharing options...
Guest dazmatic Posted April 26, 2019 Report Share Posted April 26, 2019 There's 1 variable I'd like to change, it's a PCI setting that's currently set for Linux boot which of course android and Ubuntu is. It can be changed to a Windows boot which I feel might work. Being able to change from the uefi bootloader though is brill as it means no more dodgy flashing connections.

Yes, you're right, I didn't notice that before. I can find the change that bit is. It is possible that it will work with Ubuntu and Windows after the change, with Android not having to. Thank you for a great note, I have to try it out at the weekend, maybe even today, I'll share it all. Link to comment Share on other sites More sharing options...
