Unlocking BootLoader Worked!

Unlocking boot loader worked on B1-710. Up and running CWM. :D
[Miscellaneous Android Development] Moriveon:
At least 2 men making files for A1-810. Fingers are crossed...:fingers-crossed:
[Miscellaneous Android Development] DustArma:
Well, an obvious improvement to CWM right now would be to make it portrait instead of landscape, or at least rotate it so the volume/power buttons are more easily accessible, is it possible to get other recoveries such a Philz' and TWRP to work?
[Miscellaneous Android Development] Moriveon:
Don't know about PhilZ recovery, but we can try to compile TWRP for our Iconias.
[Miscellaneous Android Development] Moriveon:
The easiest way to get root on unlocked tablets

Just download and flash an update via CWM! SuperSU will be installed too!

Ok guys

Kernel development for Acer b1-710 as started.

Im now cleaning some code, and merging some mtk patchs/ commits to properly compile.

Owners of this TAB, this is what i need from you:

- Stock boot.img (kernel) , i need to repack future compilations with stock ramdisk

- give me the output of

getprop

( do it via adb su, or via terminal emulator) dont forget to issue

su

first.

No ETA's.

Kernel B1-710

Hi there

Can you (or anyone else) provide an CWM or MTK tools Backup of your kernel (boot.img) ?

The file you provided have some issues when, unpacking ramdisk.

Im currently working on an new compilation, and need the stock ramdisk

Spoiler: Compiling kernel ;)

EDIT:

Sucefully compiled Acer's B1-710 Kernel

All i need now its the stock kernel to repack with his ramdisk ...

This one works...

Here it is the new compiled kernel:

Flash it via spflashtools (Unlock Bootloader required, make an full CWM backup just in case)

If it boots, give me an screen of the kernel version (via Antutu or any other Kernel string app)

If the kernel boots, then i can Open a Kernel Development thread

[Miscellaneous Android Development] omadhaun:
If anyone knows how to unlock/root the Acer Iconia Tab 8 (A1-840FHD), I would be interested in hearing how.

Or if people would be able to build that functionality into this toolkit and needs files/info about the device (A1-840FHD), let me know and I can provide.
[Miscellaneous Android Development] Optimissimus99:
Is this Tablet MediaTek powered? I don't think so! I think its Intel inside, which means no Support from this Toolkit ;) and there are no plans in the future for Intel CPUs as far as I know (Or can YOU find the telnet launch ;))

ok, so the b1-730hd neither, it's also intel inside. maybe list them in the first post so people wont hope and ask.

[Miscellaneous Android Development] omadhaun:
Yup, the A1-840FHD is Intel-powered, which is why I've been having trouble getting it rooted. Seems like no one talks about how to hack/root Intel-powered Android tablets.

Thanks for confirming that it won't be supported by this toolkit. I'll continue searching elsewhere in the forums.

Working on /system dump directly on the tablet

Just to share my recent findings: once you have root access (su and su daemon running), you can:

- dump /system on a SD card (I prefer external, which will not be wiped out upon factory reset)

- mount it in a loop device directly on the tablet (busybox mount is needed)

- change what you want (remove bloatware, set/fix busybox symlinks, remove old useless patches (mount -> wrapper.sh), from the command line or by script

- burn the dumped /system back to /dev/block/mmcblk0

That will save some transfers PC <-> tablet and some g(un)zip, making the whole process simpler (for me at least) and faster. Beside that, it does not require any linux working operating system beside the one you already have inside the tablet ;)

(examples given for a rooted A1-810 under KitKat)

# Dump /system to a file (assuming an external SD card has already been inserted and is mounted)
mkdir /storage/sdcard1/System_images
dd if=/dev/block/mmcblk0 of=/storage/sdcard1/System_images/system_ongoing.img bs=4096 seek=17664 count=262144
# Mount a rw copy on /data/local/mnt
mkdir /data/local/mnt
busybox mount -o loop -t ext4 /storage/sdcard1/System_images/system_ongoing.img /data/local/mnt/

## Change what you want to change.
## e.g. remove bloatware
# rm /data/local/mnt/app/7digital.apk
# rm /data/local/mnt/priv-app/Accuweather.apk

## e.g. update busybox binary (assuming the binary has been place on your SD card)
# cp /storage/sdcard1/System_images/busybox-v1.22.1-Stericson /data/local/mnt/xbin/busybox
# chmod 755 /data/local/mnt/xbin/busybox

## e.g. unroot (superuser from clockworkmod only)
# rm /data/local/mnt/xbin/su
# rm /data/local/mnt/bin/su
# rm /data/local/mnt/etc/install-recovery.sh

## change default "ls" (1 column b/w), "mount" (cannot mount loop device) and "top" (messy display) to their busybox equivalent
# ln -s busybox /data/local/mnt/bin/ls
# ln -s busybox /data/local/mnt/bin/mount
# ln -s busybox /data/local/mnt/bin/top

## unmount the file system
busybox umount /data/local/mnt/

## Burn back the modified file system to /dev/block/mmcblk0
dd if=/storage/sdcard1/System_images/system_ongoing.img of=/dev/block/mmcblk0 bs=4096 seek=17664 count=262144

Additional findings: you may want to keep a gzipped copy of your working /system partition on your PC. I suggest to perform a "zerofree" (standard unix (at least Ubuntu) command) that will fill with zeros the unused blocks of the file system (ext2, ext3 and ext4) image. It will be then more compressible.

(from Ubuntu PC):

adb pull /storage/sdcard1/System_images/system_ongoing.img
zerofree system_ongoing.img
gzip system_ongoing.img
[Miscellaneous Android Development] fREAST:
Awesome, didnt think about mounting it directly on the tab, this will save alot of time. :victory:
[Miscellaneous Android Development] PeterTheMaster:
why does the rooting depend on the processor? i thought that's a software thing. how does the intel processor prevent rooting? why is the telnet access different? does it need different credentials? what could i try?
[Miscellaneous Android Development] fREAST:
It is the software but the processor determines what software (kernel/bootloader etc) is being used. An Intel processor has a completely different kernel and stuff then what the Mediatek has, hence why the rooting will be different (exploits will be different etc).
[Miscellaneous Android Development] Calingo:
Perfect

Tried Flashing ACER ICONIA A1 810 With SP Flash Tool Using The Raw Data Provided

Works Like Charm But You Need Modified Version Of SP Flash Tool Which Is Compactiable With A1 810/811 And Rest Is On the Thread Or Here You Go

Download flashtool here: click, unpack and launch it.

Press "File" → "Open Scatter-loading file..." and choose scatter from firmware folder.

Now press "Window" → "Write Memory". One more tab will appear, open it.

Press "Open Raw data" and choose "secuoff.img" file from firmware folder.

Choose an EMMC Memory setting

Start Address: 0x3D80000

Copy value from "File Size (bytes)" to "Container Length"

Press "Write Memory", connect your turned-off tablet to PC. Progress bar will fill with red, then with gray-green, then you will see a green circle. Disconnect your tablet.

Go to Download tab, press "Download" and connect your turned-off tablet again. Progress bar will fill with red, (probably) then with purple, then with yellow, (probably) then with gray-green. After this you will see a green circle. Disconnect your A1-810 from PC and put it on charging for 10 minutes.

Finally Using My Tab After 2 Weeks of Coma :silly:

Special And Only Thanks To FireDiamond For the above Guide and link to the special version of flash tool

[Miscellaneous Android Development] Moriveon:
And your tablet shows another CPU ._.

Ok, I'll fix that update. But now you can flash RV05RC05 Classic, since patch was applied.
[Miscellaneous Android Development] superdragonpt:
Hi

Build an (MTK) kernel isnt easy.

Your device source, needs a lot more work, lets see..
[Miscellaneous Android Development] abstrkt1337:
It's the CPU of the B1-710 LOL
[Miscellaneous Android Development] DustArma:
Actually, they use the same CPU, the MT8317T is the MT6577T without a cellular radio
[Miscellaneous Android Development] Moriveon:
RV05RC05 Light can't make your tablet have MT8317 CPU, I checked all files, they are clean.

Maybe it happened beacause of your modding.

That guy got more RAM when flashing(?) lol, it's not a problem.
[Miscellaneous Android Development] superdragonpt:
Actually they aren't.

The SoC is based on MT6577 platform, they are indeed different SoC's, its not just an radio change.

They have different CPU/GPU voltages , and different changes on ARM Cortex routines.

Regards
[Miscellaneous Android Development] DustArma:
Not a problem? I wonder what will happen when the Android OS tries allocating more memory than the tablet physically has.
[Miscellaneous Android Development] Moriveon:
RV05RC05 Light

can't

make ur tablet have 1Gb RAM/MT8317T CPU. Maybe that guy have modded his tablet too much.
[Miscellaneous Android Development] daniel910821:
It's nod modd, I just installed xposed framework and RV05RC05 light, that's because I asked if someone have the same "problem".
[Miscellaneous Android Development] abstrkt1337:

Because it's not possible to edit that i think

Ty FireDiamond. Will try to flash it now :)

Well, new problem.

When I connect the tablet to my PC (tested on two machines, several cables), the preloader mtxx appears and starts to check for drivers but then the tablet seems to disconnect as the battery symbol appears no the screen. Any advice on this? Ty
[Miscellaneous Android Development] Moriveon:
Does driver checking fail when battery symbol appears on the screen?

You can try to skip driver checking, it will be done automatically when you'll click "Download" in SPFT and connect your turned-off tablet to PC.
[Miscellaneous Android Development] pjlsantos:
The problem is, i believe, that the tablet exits "flash mode"; I hear the usb disconnect sound and in device manager the preloader disappears.
[Miscellaneous Android Development] swing4thefence:
Has anybody successfully upgraded with root? A1-810

Has anybody successfully upgraded with the rootkeeper method? For me it's a catch 22. If I root first I cannot download the update, but if I download the update first then Root fails every time. somehow the presence of the update file results in the System.gz file being corrupted when it arrives on my PC. If you did get it to work, which version are you on. Maybe it's an issue that's unique to my PA_CUS1 device.

On a side note, we have 2 a1-810 tablets. One is already updated to KK and I'm sorry if this is off-topic but this seems to be the only home here on XDA where people actually gather to talk about this tab. Those of you who upgraded, do you have problems with Netflix? My wife's tablet is choppy and distorted when playing back Netflix. Has anybody else encountered this problem? has anybody SOLVED this problem?

Finally, has anybody heard of Safestrap? It's a rooting tool for the Motorola Droid Razr. It basically bypasses the locked Bootloader by tricking the phone to boot in to recovery AFTER the bootloader. So my phone has a locked bootloader but Yet I'm running PACman. I wonder if it might be a solution for our devices.
[Miscellaneous Android Development] Moriveon:
It's OK for Acer tablets, for example,

B1-A71 disappears after 28 seconds

B1-710 disappears after 13 seconds

A1-810 disappears after 3 seconds

Just try to flash ;)
[Miscellaneous Android Development] pjlsantos:
No go :(

0. Retry. You can see that error when flashing first time.

1. Use another USB cable.

2. Remove battery from tablet and try to flash.

If these steps are not helped you, PM me, I've something to test...
[Miscellaneous Android Development] pjlsantos:
Same error after several retries with several cables. As for the battery, I disconnected it from the tablet (did not remove it completely, as I wouldn't like to break anything) and it starts to go on, off, on, off. PM On the way :)
