Hey mate. Maybe you can lend a hand.

A 501 user has issues. Can't NVflash any of the bootloaders. Here is one link which is recent.

Tried with various methods.

Original thread is;

User is Tommmalii.

Any suggestions?
[Acer Iconia A500] maris__:
Just an idea: gersma's AfterOTA full version requires switching off user account control. Maybe the UCA interferes with the APX mode also in the case you are refering to.

Best regards, maris

Thanks Maris. Will pass the info.

[Acer Iconia A500] BakaNeko59:
Skrilax,

Does this patched bootloader disable the "full factory reset" that is done by flipping the rotation lock switch with the volume up pressed during boot? I have tried to do this reset at least a dozen times, but I keep ending up in the bootmenu from this bootloader. Or is it just a matter of timing? Is there any way to add this full reset as an option on the bootmenu or is it purely controlled by hardware?

Thanks.
[Acer Iconia A500] Skrilax_CZ:
It's written in the FAQ. Yes, it's disabled. Use "fastboot erase userdata".
[Acer Iconia A500] BakaNeko59:
Thanks. Completely missed that.

The reason I asked is I continue to have problems restoring data from a CWM backup. I receive "error restoring /data" even though the backup checksums are correct. I think I may have a problem with my ram so I'm trying to a very thorough format with verify so that any bad blocks get mapped out. Any recommendations on tools to use for this? Is the fastboot method as good as any others? Is there something in the Android SDK that would work better?

Thanks again.
[Acer Iconia A500] dibb_nz:
pretty sure civ said earlier on in the piece that restoring /data from HC may cause a few issues.....

yep u cant beat fastboot i reckon - which is also a part of the latest sdk - theres a download zip to a mini sdk in my CPUID thread:)
[Acer Iconia A500] BakaNeko59:
I'm not restoring from HC. This is a backup I just made this morning as a test (currently running v7 boot loader, flexreaper extreme rev 2 and 1.7.3 recovery). The backup went fine MD5 checks out but restore fails. This has been the case almost since I started rooting. Was really a big problem every time Civato updated since he wanted a full format each time. Not so big now that he's only doing updates :-)

Thanks again.
[Acer Iconia A500] dibb_nz:
sweet as m8 i'm still running 1.7.2 too scared to change anything....just in case:)
[Acer Iconia A500] MDMonster:
Just wondering, but anyone know if there's ant chance of a kernel like this for the A100?? O.o

Sent from Iconia A100 rocking CM9 with OC'd kernel currently @1. 5GHz
[Acer Iconia A500] ezterry:
This thread is about a boot loader not a kernel.. the a100 and a500 kernels are very similar.. actually custom ones these days are from the same source code (but configured differently)

If the boot loader is very similar to the a500's it may be possible to make a very similar hack.. the reason no one has is an unlockable ics boot loader exists for the a100 allowing custom kernels, the a500 the unlock functions didn't work.. this was bypassed and now a bunch more modifications have also been added.
[Acer Iconia A500] meduza:
@bakaneko59,

...hmm..., is it possible that you change the backups name?

I did it once (at the beginning of my rooting experience) without following the rules for renaming, the result was the same as you describe.

Anybody has a good monospace font and bootloader splash screen (full size 1280x800)?

I started playing with framebuffer and custom GUI, but it looks like recovery now (yes, used recovery font for now) :P

Ok, I'll check & render that one. Complete size limit for the bootmenu application (code + images) is cca 455 kB. That should be enough for font png and bootloader logo png.
[Acer Iconia A500] sda.171:
So i flashed ICS unlocked v7 yesterday -followed by civatos latest Extreme Rom-

And i have no accelerometer- and not only accelerometer but none of the sensors-

My device does not rotate with orientation changes- Gyro games fail to work- Sensor apps have no data feed (none of the sensors seem to be working :O).

A few more users are encountering the same/similar problem- for some flashing back to v4 has helped- others managed to reboot with rotation lock on and fix it- and the rest couldnt fix it at all :(

Could this be a bootloader related issue?- Cos with Hc bootloader everything seems to be wrking-With v7 unlocked bl, I changed ics roms and recoveries but the issue persists.

Thanks :)- and pls help :)

Btw your signature link is not working- the candlyfloss one :S

thanks

V0.4 isn't out yet but v0.3.3 is on the site that can't be named. Clue - it ends in "owners" and starts with "tegra" ;)

Candyfloss.tk for some reason got seized by dot.tk for no reason. Abuse or some shizz?! I'm looking into it and if necessary I'll move all my tools over to blackthund3r.co.uk (same server so I'll do it if necessary)

Ufff, jpg loading works (thanks GRUB :D).

So right now, two jpgs are used. One for font, 960x18 jpg image, font size 10x18, 96 characters, starting with 0x20 (space). The second one is bootsplash logo, 1280x800 image. Restriction for the jpgs: RGB (well same as for GRUB).

Font.jpg is on offset 622592, size limit 20 kB, Bootsplash.jpg is on offset 643072, size limit for now 200 kB. Just dd it if you want to change it, for now. Current preview in attachment, things like fastboot, BL update messages need yet to be updated.

Also FB is a bit hacked, no surface switching for now, so you can see how memcpy progresses on the screen :p
[Acer Iconia A500] amphi66:
Bootloader related: Boot Animations are typically 'cute' graphics used as a "place holder" during the boot process. Rather than the graphic, in Android is it possible to dump a listing to the screen to observe the boot process activity in real-time, such as a verbose boot in Windows or Linux? Thanks.
[Acer Iconia A500] Skrilax_CZ:
In attachment, today's V8.

- Finished GUI revamp (green openSuse background, white DejaVu Mono font)

- Fastboot command handler and execution is completely in source code (i.e only low level functions such as send and receive and few unknown initialization functions are used from Acer BL).

- Bootloader flashing using fastboot improved and will wipe cache automatically if bad bootloader blob sent

Note: I didn't test the new fastboot code much, kernel images flashed fine, wasn't trying big partitions such as flexrom and system. It won't use cache anymore as a staging partition (that was stupid - download partition to cache and then just copy it).

So, by having fastboot and framebuffer mostly finished, the only thing left is a few partition related functions and the actual booting to be in source code :)

Then we can go for extfs boot.

That can be done, although it's better to use UART for that.

[Acer Iconia A500] garringm:
Back in my ATT Tilt days a guy aroud here named DZO made a secondary bootloader for the Tilt and several other devices that were nearly identical, there was no boot image but rather a listing on the screen as everything was started and initialized however one of the coolest feature that I have ever seen and wish at times I still had it was a boot to recovery option built in to the normal boot process, it would get to a spot just before Android startede and would ask if you wanted to boot into recovery. He was probly by far one of the best developers amongst XDA. He had a hand in just about all the Winmo converted to Android HTC devices I think.
[Acer Iconia A500] amphi66:
Sounds exactly like where I would like to go. Seems useful & provides more information about one's hardware. Unfortunately I don't have the knowlege to continue (yet)! Thanks.

Bootloader v8zip. Am I supposed to be able to just flash this with CWM? I have v6 installed. I have tried this one and the v7 earlier and the installation always aborts!
[Acer Iconia A500] elborak:
No (unless you repack the new v8 bootloader.blob into an existing update zip).
[Acer Iconia A500] tennessee_titan:
I am afraid I don't understand your answer. Where is a walkthrough to "fastboot flash". I see it referred to in a lot of places, but can't find how to do it!

Just tell me exactly step by step how to flash v8.
[Acer Iconia A500] wlk0:
Check the OP, fastboot flash syntax is explained.
[Acer Iconia A500] Skrilax_CZ:
Fastboot comes with Android SDK, just like ADB. I'm not packing CWM updates for prereleases, once final V8 is out (perhaps today night or tomorrow), there will be CWM update.zip in OP.
[Acer Iconia A500] lowsum:
What about something like this as fullscreen bootsplash...

I guess you have something in mind other than a plain green screen?
[Acer Iconia A500] blackthund3r:
Omg that boot splash is beautiful :O
[Acer Iconia A500] Zatta:
I have just flashed v8 to my device, I really like the green screen (mainly the idea of it). For one or another reason I can't manage to make the blob file into a cwm flashable zip on the device so I had to turn to my pc for it. Anyway, thanks for your great work.

Taptalked u see
[Acer Iconia A500] tennessee_titan:
yes the syntax is explained, but what do I do with it? I need the specific commands, how I set it up, where I type them, etc....

I know nothing about how all of this works!
[Acer Iconia A500] Skrilax_CZ:
Don't forget about the layout:

Top center is bootloader version & current status. Below comes the bootmenu. It has to be something on which you have to be able to write text.

Anyway it will be customizable, along with the font colors.

Just install Android SDK and then do the command "fastboot flash bootloader bootloader.blob" from console (in the directory where your fastboot binary is). Or alternatively, download v7 CWM update.zip in OP, open it with winrar, and replace the bootloader.blob with the new one (keep the name bootloader.blob in the archive).
[Acer Iconia A500] tennessee_titan:
Used the update.zip method. SDK writeups scared me away from that. Bottom line. It didn't update. CWM took the update, gave all the right indications and when I rebooted I was still on rev 7. So I will wait for the next APK package...

Thanks anyway
[Acer Iconia A500] blackthund3r:
Amazing bootloader as ever Skrilax - keep up the awesome work!
[Acer Iconia A500] wlk0:
Skrilax, in case you missed it, new 0.3.14 bootloader released in this Acer_A501_4.066.29_041.219.03_COM_GEN1 leak for A501.

Contains code changes, you might want to check it.
[Acer Iconia A500] Skrilax_CZ:
The bootloader is based on 0.03.14. Also the bootloader is quite heavily patched now, I will not be rebasing it unless there is a proper reason, also if there will be such one, I'll wait for final release. Don't forget that most things that we use i.e fastboot, selecting boot partition etc. is fully controlled by open source code.
[Acer Iconia A500] Skrilax_CZ:

Flashed v8 Blue. Very nice. Let's just take a moment to look back to the bootloader dark ages when it was textless, virtuall graphicless (bar a basic Acer logo), awful for developers (no easy access to fastboot and support for (ZOMFG) ONLY ONE KERNEL!).

So the point is.... Acer could learn a thing or too ;)
[Acer Iconia A500] tennessee_titan:
Glad you can flash the bootloader. I wish I could (see previous posts)..........

I can't even find your APX bundles any more!

Sorry for all my ranting.

Got the APX package and flashed. Great!

Thank you
[Acer Iconia A500] Skrilax_CZ:
I've forgot to mention that the V8 bootloader has new "fastboot oem sbk" command in the changelog, that will display your SBK on the tablet if you lose it (calculates from serial number).

That is just way too much!!!!!!

Just simply awesome....
[Acer Iconia A500] dabl8:
Is there a command for booting into bootmenu?
[Acer Iconia A500] Moscow Desire:
Vocal command... . Set your android settings to to "open Mic-iPad compatible". Then vocally say "Open-sez-a-me".

In a serious nature... just with tab off. Hold Vol+, then PWR. Hold till you get the menu.;)

This is my custom Flexreaper unlocked bootloader

see attachments , flash with cwm
[Acer Iconia A500] lowsum:
I need help..did something stupid. I downloaded v8 cwm package and replace the blob file with another one generated with the tool to change the splash screen...after flashing the result is a hard brick. Usually in these case I can restore it with timmydean EUU 3.2.1 flasher, but this time it doesn't work. I can go in APX but the flashing process always fail. :confused: damn me!

edit: Tried with blackthunder flash utility and it looks like it doesn't go into APX, the power led is on though.
[Acer Iconia A500] Skrilax_CZ:
Can you upload the generated blob file? It should not flash anything if you use bad format. It's probably bad jpg :/

You have to restore via APX mode.
[Acer Iconia A500] lowsum:
I attached the cwm zip, the modified blob file is inside...unfortunately apx looks broken. EUU do wake the tablet, I can see the acer logo and entering download mode but no progress is made...blackthunder's apx flash tool doesn't recognize the tablet in apx... thanks for your help!

edit: Everybody do not flash the attached file

Good to know I wasn't the only one having trouble with this. Try the v3.2 APX tool. It works better for me than 3.3....

Anyway great wrk
[Acer Iconia A500] amphi66:
Wouldn't think it could be the bootloader. No problem here with any aspect of Civ's work. Insure your rotation switch is off & do a full wipe w/ reinstall (use advanced restore to restore your /data to retain your personal settings & apps). Goodluck!
[Acer Iconia A500] sda.171:
I guess this is a known issue. There are no problems with hc bl and hc rom or hc bl and ics rom. Check my thread at the question n answer section. Few more users are facing this issue.

[Acer Iconia A500] BakaNeko59:
Is there ANY way that the bootloader could affect the operation of the tablet once it's past the boot? Specifically could it have anything to do with sleep of death problems? I'd think not but I don't know enough about the boot sequence to know for sure.
[Acer Iconia A500] Moscow Desire:
In laymans terms, yes. Sort of. With ics the kernel communicates more with the boot loader, which is why certain patches had to be made to both. Your kernel in flexreaper should have the sod problem patched. Has been for a long time. That's why there are very few sod's anymore.
[Acer Iconia A500] blackthund3r:
Check drivers. Drivers drivers drivers ;)

Check in Device Manager when it's connected too :)
[Acer Iconia A500] lowsum:
Don't worry, I must have reinstalled the driver over 20 time in the last 6 hours rebooted and all that, but now after so many attempts it no longer recharge. I shouldn't have change the splash screen...grrr Hope Acer will take it fo repair.
[Acer Iconia A500] blackthund3r:
Not charging is a different issue. Are you stuck in apx mode? Try poking the reset button inside and see if there's life
[Acer Iconia A500] Skrilax_CZ:
I flashed the bootloader with fastboot just fine, so it's not problem with it. Besides, APX mode doesn't use the bootloader at all, it's sent via USB. Could be just unlucky timing of some HW issue. EUU is using --create command, that repartitions the tablet and flashes complete image, and that one should work in every time, i.e even if the tablet eMMC is completely wiped - i.e it is able to restore the tablet after however you screw it. If this doesn't work, then I'd say it's either your PC problem, or HW problem.
[Acer Iconia A500] blackthund3r:
If it's not charging I'd be inclined to say dodgy charger or borked power management chip / EC

[Acer Iconia A500] BakaNeko59:
For the record - I had no sod with flexreaper 12.5 or rf1 with the 021 kernel and earlier (v3?) unlocked boot loader. I have now reverted to totally unrooted stock (with full wipe using superwipe [http://www.acertabletforum.com/forum/acer-a200-hacking/3909-acer-a200-superwipe-tool-wipe-all-partitions-your-tab.html] and going back to 3.2.1 with ota up to 4.0.3). I had sod this morning with this configuration - NO root, NO custom bootloader, NO custom recovery... Just did a rotation toggle reset (per advice from Acer) and I'll edit this later to let you know how that works out.

EDIT - 3 hours and multiple screen timeout/sleep sessions later - 1 sod so far...
