Hi,
I would like to have some informations about the Google Nexus 10 Bootloader (and more generally all google device bootloader). Is it possible to reverse-engineering and modify some opcode, or it's signed by the hardware device like the samsung device (I9100 bootloader & co) ? OR is it a way to put my own bootloader based on Das U-Boot on the device ?
The goal is to turn on some CPU mode (hypervisor) to run the kernel in a special mode for virtualization purpose.
Is it sbl.bin who setup CPU mode for the kernel ?
Is bootloader wrapper or 'trampoline like' (which is called by the real bootloader, and will call the kernel with some additional cpu options) is a viable solution ? [1][2]
The cpu load the kernel in a non-secure SVC mode or secure SVC mode ?

Thanks for your help!

Is the Samsung guys from [3] has the right the change (and sign) the bootloader to enable HYP-mode, or did they find another way to do this ?
Thanks!

Any help on bootloader modification? I have a phone with bricked eMMC and I need to modify bootloader to load boot.img (kernel+ramdisk) from external sd card instead of eMMC if it's possible.

Ok I need you help please, I have the same problem with my htc 7 surround of AT&T, but I didn´t use the tool "unlock by XTC clip". My phone worked well, but the last week, it freezing in the logo "HTC" and don´t pass from here; it do not start wp7.
I use this tool that you give from megaupload but when the program verify the image version of my htc - it is in blank, my phone phone don´t have image version- I don´t know what I have to do. I use everything to install a new windows phone 7 operating system to my htc surround.
please give me a response...

waiting for your response.

Do not use this to install an Over-The-Air update from EVGA/Nvidia. Use the stock recovery for that.
Do not use this on any Tegra Note 7 besides the one by EVGA. Other variants are untested.
Download: CWM for Tegra Note 7
Instructions:
--- MUST BE UNLOCKED!--- (fastboot oem unlock) Note, that will wipe data.
Code:
fastboot flash recovery tegranote-cwm.img
Bugs:
Upside down graphics (PS: The recovery isn't upside down, you're just holding it wrong :-$)
No external SD-card or USB OTG support.
Does NOT backup BOOT.IMG, RECOVERY.IMG, or STAGING.
Source (Device Tree): Device Tree for Tegra Note 7 CWM
Source (CWM): Github for CM11 Android_bootable_recovery
Source (Kernel): Ask NVIDIA! It's a stock kernel from the 4.3 firmware.
Changes I made into CWM are included as attachments if you want them (rename recovery.c.txt to recovery.c and place in /bootable/recovery/) (copy icon_clockwork.png into /bootable/recovery/res/images/). I swapped the Volume Keys Up and Down because this one is still upside down. Doesn't seem to be a good way to go about flipping it without breaking things. If you can fix it, please do.

table flip time (sorry I don't know an emoji for flipping a display round..)
tested on Advent Vega Note 7
There are some slight issues, like the log is still upsidedown, and the font is massively small (can be customised in the boardconfig), but other than that, should be fine
Whats required to make SDcard1 mount point to fully work?
I have also pestered Nvidia for Kernel OpenSource but as of yet still waiting to get a reply.
I can get a full Partition read out if that is required though.
Hello. Some time ago I flashed stock rom ALE-L21C22B160 and I got blank page in "Motion control" so I went to Huawei site and I downloaded C432B170. Then I extracted boot, recovery and system, then I flashed it without any problems.

Then I simply did "fastboot reboot" and my device rebooted with the old firmware, nothing changed at all.
I think you also need to flash to Cust.img

Thanks, it worked, but I can't get proper firmware, I'm always getting one of those:
- blank "Motion control" page
- phone getting into rescue mode due to some problem with boot.img
Can you give me a link to firmware that actually works and has motion control? Thanks.

It says "Attention! Please update system again Error! Func NO : 11 (recovery image) Error NO : 2 (load failed!)". Oh man, is there any hope for me? :crying:
did you unlock the bootloader ? and enabled USB bedugging ? ( sorry if it's stupid question )
any way , here is a thread that you do not need to flash with fastboot via commands ( C432B052 Rom version ) , it will automatically do the job , and i think it would work fine for you , and also if you want to have marshmallow , you can simply follow the reste of the thread

Hi,

I test many manipulations to get something on my phone other than "Bootloader, Locked".

Hey there. Got the same problem. Tried everything. Nothing happens. Have you got your problem solved yet?
The same problem

Only way to solve this is taking the phone to technical service. Done it myself. Be careful tought, they will try to make you change the entire mother board (280€), but if you insist they will "find a way" to install the correct software in your phone and leave it as if it was new
it is possible to recovery via dongle ... but sn and imei can be lost

Hello my friends. I have an android hand unit like the one on the link.

I need to do firmware update οr to rout this HU.
Here's a difference in the model's name... The factory information is different from the CPU-Z information.
The seller of course does not help. He forcefully responds to messages and does not understand.

I only ask you 2 things.....Do a firmware upgrade or root the device.
The main problem is the radio application. While I have English as my primary language, the radio only holds Polish and does not have a good signal.
Please Help me
any help?
Look for this instruction in 4pda.ru forum https://4pda.ru/forum/index.php?showtopic=936535&st=11880
Easy! For some reason, it is not described in detail and simply here.
I will try:
- download our scatter file to the computer (laptop);
- Download FlashTool with SP_Driver_v2.0 (firewood) and install on the computer (laptop);
- Download SuperSU.zip and throw in the root of the body;
- Download Android Terminal and install on the body;
- Download also TWRP, this one came up to me, the rest mirrors;
- rename TWRP to recovery.img - this is important!
- we throw recovery.img next to our scatter file;
- open FlashTool, load our scatter file, see that the checkmark is only on recovery! ;
- further according to the scheme as described on the forum - click Download, connect the switched off body and wait for success!
Success will be, of course, if the firewood is already standing and the dad-dad cord is whole.
- Now you need to reboot into recovery. to do this, turn on the body, launch Android Terminal, give the reboot recovery command;
- from TWRP we put zip SuperSU;
- ALL! We reboot and rejoice.
I hope it turned out simple and clear. Good luck!
