[Q] [Bootloader] Status of U-Boot - Acer Iconia A500

Hi !
It's quite a shame I can't post that question directly on the good thread, but well, it's how this forum is done.
So, I'd like to know what became of the u-boot bootloader that sp3dev did try some months ago:
http://forum.xda-developers.com/showpost.php?p=23004214&postcount=53
Is it part of the V3 bootloader ? Has it been abandoned ? Does it actually work ?
The goal would be to be able to boot a simple Linux kernel from USB, and from there to try various Linux "products": Mer/Nemo, PlasmaActive, etc. All of that, without losing the possibility to have a custom Android recovery + Android installed on eMMC.

Native Linux - Bootloader Question. (Almost a Brick)

Hi everybody,
I was messing a bit with Linux on the Iconia and I was able to get it working following the instructions in the post of sp3dev (http://forum.xda-developers.com/showthread.php?t=1158260)
I've used the sp3dev kernel and i made a rootfs image with ubuntu. Everything is working fine.
But now, I want to know if there is any way to get back to the CWM bootloader because i have a bootloop on the Android Rom. (Civato-Flex)
Is this possible or I'm stuck with linuxmint forever? xD!
I didn't try anything yet because i don't want to brick completely my tablet.
Thanks in advance!
To clarify: I can't boot back to CWM because i've installed another recovery image (In this case Sp3dev kernel)
There is a thread inbdev section on how to push the recovery thru adb be sure to use the its majic while doing as .the thread I think is titled its magic.
Good luck. I did this myself as well aa few weeks back to try Linux.
but im far from a expert about anything tech in any way
Just a dumb blonde here.
Chics rule.
Well, thank you very much for the info. I was reading a lot, and I was able mixing some things to get it working through that guide.
To anybody messing with this, GET THE UID before doing anything.
Thanks again Erika and all the devs here!!!

you should download cwm.img then open terminal and do the following: dd if=/..../CWM.img of=/dev/mmcblk0p1, on android is dev/block/mmcblk0p1. if it doesnt work then you should download EUU from OTA thread. I don't hnow itsmagic works or no on linux. sorry if your understand my bad english. goodluck.

This is the only Linux for the tablet, but it's very buggy and unstable. I hope they continue development on this, but not sure if they will.

Newbie seeks informations

Hi.. Im new here with this device i read almost every single post here but there are quite a few things that I don't get it..
What is bootloader? Should i unlock it before rooting the device? And recovery here is in Chinese so shall i get TWRP instead? Also about the flashing Roms issue that erase imei and SN.. why would that happen? And How can i take a backup for these in case i lose them.. Some people mentioned SN writing tools but some people says its not working so im abit confused.. And has anyone noticed that the flashlight of the mobile is actually yellow that affects camera's captures? I would be really grateful if someone helps
1. What is a Bootloader?
Hboot, or we may call it Boot-loader, is like BIOS to windows. It is the first thing that runs when you boot up your Android device. It packages the instructions to boot operating system kernel and most of them are specifically designed to run their own debugging or modification environment.
Every Android phone has a boot-loader that instructs the operating system kernel to boot normally. But you need to understand one thing here that as Android OS is an open source OS and is available on a variety of different hardware, every manufacturer has their own version of bootloader specific for the hardware present in it’s environment.
2. Should you unlock it before rooting the device?
It solely depends on you whether you want to unlock it or not. Unlocking bootloader will give you access to installing custom recoveries on your phone and also you can use custom kernels to boost up phone's performance or simply get more battery juice. Since our K4 note doesn't have any custom kernels so good luck with that.
Warning: Unlocking Boot-loader voids phone's warranty​
3. Why does IMEI/SN erases while flashing ROM's
People don't read the tutorial properly. They blame the OP instead when they do something wrong and loose their IMEI/SN.
What basically happens is, when flashing ROM's through SP flash tools, They should flash it in "DOWNLOAD" mode only and not in "Format ALL" mode. People who all lost their IMEI basically did this mistake.
4. How to Backup and Restore your IMEI/SN (NVRAM)
All the device specific details such as IMEI, SN, MAC addresses are stored in a partition called as NVRAM. So backing it up will indirectly be referring to backing up your IMEI/SN. Here is how you can do it.. LINK
5. How to install Recovery?
if you are on Marshmallow then you will be able to install recovery through this thread. LINK
6. Yellow Flashilight problem?
This bug is introduced in Android V6.0 that is marshmallow. Actually this is not truly a bug. Unlike on Lollipop which had only one LED light enabled during Camera operations, Lenovo decided to enable both of the LED's (That is white and yellow) to give the images a more true LIVELY appeal.
But terming this as bug here because nobody liked it and users were pissed off straightaway. Hopefully, Lenovo will fix it soon.
Hit Thanks if i helped..​

Android to Windows Hack or Dual boot Option?

So im thinking of purchasing one of these when the come out here and i was wondering about an android to windows os hack. Will there be one in the immediate future and will dual booting be an option?
The hardware is exactly the same.
There must be a way to dual boot, hopefully others on this forum can figure out how to do this if Lenovo doesn't facilitate dual boot themselves
Best
I believe there's a different BIOS for Win vs Android. Could have sworn I saw the Windows BIOS posted on the Lenovo support site prior to the Oct 17 launch. It seems gone now though, unless I'm missing something or went to the wrong link? Unlikely you can install Win without a different BIOS.
There is some clear hardware differences with the Android and Windows tablets. Specifically, 2 different physical layouts for the halo keyboard, where the windows one has defined left and right mouse click buttons. There doesn't seem to be any way of accessing the BIOS on the Android tablet, and it does have the usual Android power + volume up, power + volume down recovery options, so it looks like it boot directly to the boot loader.
The Bios is still there ... but how would you flash it?
http://support.lenovo.com/de/de/products/Tablets/Yoga-Series/YOGA-Book/downloads/DS119182
ok so there is also android open source code available in their site, any chance of making a custom rom?
I wonder if we could flash the Chuwi 12 roms onto this given that Chuwi12 has dual boot already?
This is reallly really stupid to me, why not provide dual boot in the first place? I would not mind shelling out $100 more for a dual boot version. Now if I want the windows version I will need to spend another $550 to get another OS with the same device. I will end up having 2 same devices, but that is so anti-mobile really. Do I have to carry 2 hardware devices so i can have 2 OSes at the same time?
Lenovo get some grip please and provide a dual OS version.
win 10 driver
Today, the windos 10 drivers are online..
The drivers you get with levono support with input of the serial number
It must now be possible to build a dual system
Tastertur chipset audio and more .

Could you post the link for the windows 10 drivers? also any idea on how to unlock the bootloader?
Hi,
earthCallingAngela did unlock the bootlader. .
My background knowledge about booting is very low. But I think there are huge differences between Android and Windows. I think If a system can boot via PC-Bios or Android-Boot-Loader is "on the chip". If this is correct you would need a Android-Boot-Loader that does boot into a windows ... IMO this is no "easy to do". May be the guys who did create Remix OS found a way to do that ...?
Can we use Chuwi 12's disk image somehow? It comes with dual boot.

Are the two the same hardware? My understanding is that unless the hardware is very similar, you can't use other ROMs without a *TON* of work.
so i was able to install android x86 6.0 on my yoga book, unfortunately i managed to do it over my windows install so now i just need to reinstall windows lol.....

Hi & Happy New Year
Now it's possible to get root with android version
I have a YogaBook with Windows version ; Someone can make a backup Android version?
Maybe it's possible to create a dual boot with the windows version I cross the fingers :fingers-crossed:
Where and how?

someone can said me, where i found an android image? (original yoga book, of course) i try to install Remix OS and Android-x86 6.0-r1 released from Android-x86.org but, its can't run. graphics issues and reboot.
i install in a MicroSD and boot it booting yogabook hold volume up + power boton and select boot menu, but it fail on boot.
i have yoga book windows. any idea?
thanks
sorry for my english..
I'm exploring this as well.
Since the BIOS and drivers available (just tested with my serial#), it does seem like it would be relatively easy to dual-boot, provided you can get past the loader issue.
I've done many dual-boot setups, just not since the Win7 days, with the Win8 and forward it's gotten quite a bit trickier, the loader does a bunch of "extra" stuff, boot timing and such, to protect itself.
I've also never done an Android/Windows dual-boot, mostly just Win/Win or Win/Unix.
I think you'd have to figure out how to bootstrap these, so the custom loader can take over, and load from there, but this is a bit beyond my Android capabilities.
Has anyone even tried this? I assume the power/volume keys must work, to get at the loader?
Hi there !
I've just unlocked my Yoga Book's android bootloader and made a backup. I'm trying to install Windows 10 and replace Android with it. The problem is that I don't know how to boot the device from the USB drive.
Does anyone know how to do that ? Even if rooting is required ?
P.S. : I can't google it as all results link to "how to boot a PC from android device", which is the reverse...

simple...you can't do that! it's not possible to boot usb from android bootloader or recovery.

Any active developers here yet?

Hey there;
| Bull****/intro part, skip this if you are not interested, which I do sincerely understand lol |
Let me introduce myself, as a former Sony Xperia M2 owner I really liked my phone and used it for quite a bloody while.
As I had the device longer more custom roms, recovery files where made. And then, my M2 died. In requiem my old friend.
Now, I bought the L1 (And perhaps your the proud owner of one of these beauties as well)
and heck, I really like this!
Exept for a few major parts..
| Question part, this is pretty nice |
For as far as I have searched, there is no custom recovery for the L1, did anyone compile one yet? If so, would you mind sharing?
And did anyone make progress on rooting, or unlocking the bootloader of this phone?
Cheers guys,
~ Blizem
I'd love to have some development on this phone it's awesome
idk but i managed to unlock bootloader
well it took more than a day unlock my bootloader but since I am familiar with one click roots I am not really sure where I should go.
EDIT: when I power my phone into fastboot I don't get displayed with anything except for that blue LED. The only way I can access fastboot is either holding down vol + and plugging it in to my PC or by using adb.
When I enter recovery mode (since i have unlocked my bootloader) I get an error: your device is unlocked but the image was not working rebooting in 5 seconds(I tried flashing twrp using xperia L's image).
any help would be appreciated
thanks in advance
I am learning how to work on kernel from @rrvuhpg
The only problem is I have no experience.
I am just a rookie and I made a modified kernel for Magisk to root.
Check out the guide forum. It's made for G3313 but it should work with other variations.
