Hi can you again convert that picture to a new cwm boot loader v9 please thanks
[Acer Iconia A500] mixednuts:
I think it was [MENTION=3986004]civato[/MENTION] that initially did it. Not sure if he's still watching this thread anymore. You could PM?

But, you really should try it yourself... don't remember it being that difficult.
[Acer Iconia A500] internetpilot:
It's actually very easy and outlined in the OP I believe, including links to the app that adds whatever pic you want to use and saves the new blob for you.
[Acer Iconia A500] Skrilax_CZ:
You can do it yourself, just see OP and download the tool.

Need Help ASAP

There are several of us running into this problem

Any help would be appreciated

I have flashed two different ROMS (CM10-FLEX_v6supercharged_Aroma-Rev3.4 and CM10) and can't get past the bootloader screen.
[Acer Iconia A500] Skrilax_CZ:
Try to wipe (format) cache in recovery.
[Acer Iconia A500] CanuckinPA:
Done that but no change. Still stuck on bootloader screen
[Acer Iconia A500] Skrilax_CZ:
If formatting data or cache doesn't help you flashed it badly (maybe problem with recovery).
[Acer Iconia A500] CanuckinPA:
Ok, I've tried to reflash the bootloader, twice using the instructions here, and once using one of your bundles on Blackthund3r's flash utility.

Error messages using the command prompt method, while the flash utility froze up. :confused:
[Acer Iconia A500] mixednuts:
Perhaps a driver issue... when using Blackthund3r's tool have you tried entering APX mode manually?
[Acer Iconia A500] CanuckinPA:
Yes, I put the tab into APX mode before starting the flash tool. Just tried again this morning flashing a different Skrilax bundle. This time I got the Acer logo and Acer Iconia APX Mode on the tab screen, but the flash tool again seems to be frozen.

UPDATE: I rebooted and was able to get into recovery mode, but ran into several error messages while trying to wipe and reflash the ROM. I assume that is because flashing the bootloader failed.
[Acer Iconia A500] mixednuts:
When your tablet entered APX mode do you see the APX device listed under your PC devices?
[Acer Iconia A500] CanuckinPA:
Yes

UPDATE: I was able to flash Skrilax's V4 bootloader using BT's Flash Tool. Then I flashed V9 and am now able to get into recovery mode.

I did a complete wipe; however, when I try to flash CM-10-Flex-V6Supercharged, the Aroma Installer starts, but the flash locks on "Please Wait"

Tried flashing CM-10.1 - it started installing, but appears to have locked up about 2/3 of the way through the install. :confused:

Tried to flash Supercharged a second time. This time it started but has locked up at 30% complete.

Is there ANYONE out there who is able to offer any help to get my tablet back? :(
[Acer Iconia A500] mixednuts:
Now that you've got the boot loader going other questions don't really belong here.

Anyway, what recovery were you using when trying to flash civato's JB?
[Acer Iconia A500] CanuckinPA:
CWM-based Recovery v5.5.0.x (thor2002ro rev1.7)

Boot into recovery this morning and I get error messages:

Can't mount or open cache/recovery/log and last_log

Can't mount sd card

I have used BabSector and followed the instructions here. I got back to the Skrilax V8 bootloader and was able to successfully flash CM10-FLEX_V6Supercharged.

However, on rebooting after flashing the ROM, it's right back to locking on the bootloader screen. Clearly, there is a problem with the bootloader.

If there's no solution, is there another bootloader that will allow me and others to flash ROMs and get past the bootloader screen?
[Acer Iconia A500] mixednuts:
Sorry to hear that you're having a hard time getting it going. I didn't have any issues, besides USB drivers, in getting the bootloader and recovery to flash. Beyond that I can't help much as I'm no expert.

There are, however, some ROM and recoveries available that can be flashed \ used with the locked Acer HoneyComb bootloader. Take a gander Be very careful if downgrading bootloaders.
[Acer Iconia A500] internetpilot:
I have been running the patched ICS bootloader for a while now. Recently upgraded to v9, and after trying to wipe and re-flash ReFlex v7 ROM to start from scratch, I'm now at the exact point you are -- stuck on a bootloader screen. Doesn't matter what ROM I try to flash now or what backup I restore -- same thing. I was running TWRP (whatever the latest version is for the A500), but when all this started I suspected it was a bad wipe or ROM flash (TWRP never really worked well for me) so I switched back to RA. The wipe and flash seemed to go better, but I'm still stuck at the bootloader screen.

I'm going to try to flash v8 bootloader and try CWM recovery to wipe/flash everything again, but this isn't looking too good.

Anyone know what's going on?

EDIT: Nevermind. It was apparently a combination of quirky TWRP wipes (my A500 doesn't seem to like TWRP no matter how much I try to force it to) and a bad flash. I think the Aroma installation was throwing me for a loop there for a while, too.

Regardless it's booting now without issue. Thanks and sorry for the false alarm!
[Acer Iconia A500] gemneye:
Stuck on Bootscreen

I am having almost the same issue as [MENTION=3240650]Icersman[/MENTION].

I used blackthunder's A500APXFlash tool to flash (A500_A501_ICS_V9_bootloader.a500apx).

I went into recovery, which was the recovery that came with A500_A501_ICS_V9_bootloader.a500apx. I wiped factory, wiped cache, and wiped davlik-cache. I then formatted /system, /data, /cache, /flexrom.

I installed this custom ROM: CM10-FLEX_V6Supercharged_Rev3.4.

It went through the aroma installer and got to the screen that said push "next" to reboot. After the reboot, the Skrilax_CZ's bootloader v9 screen appears and I get the "Booting android image from LNX partition ..." message, but the tablet hangs there.

I have since tried installing different ROMs and none of them have worked. I also tried using "fastboot erase userdata" and "fastboot erase cache" to start over. Although I was able to run the fastboot commands, and I was able to repeat steps listed above, the end result is exactly the same. The tablet just hangs at the boot screen. I can get into recovery with (Volume-Down + Power) and can get into menu (Volume-up + Power), but I just cannot seem to get a custom ROM to boot.

Are there any things left to try?

Thank You.
[Acer Iconia A500] CanuckinPA:
I flashed RA recovery today, but it won't mount or open cache

Now, when I try to use the BabSector instructions, the flash fails.

I don't know what I've done :confused:

A noob question but make it sense to upgrade bootloader v7 to v9.

I have bootloader v7.

So i dont wanna play with the bootloader and brick my tab...:eek:

Can i easy flash the v9 zip file via thor recovery v1.7.3?
[Acer Iconia A500] meduza:
Yes, you can flash it that way :)

I learned recently that the upgrade is not really necessary, if you are using only one boot partition....

I`m using only android (no linux) but even though I upgraded and didn't experience nothing bad :)

m.
[Acer Iconia A500] frischeis:
How does the multi-booting option is working?

Can i select on starting screen witch partition i want (linux or android)?

Or can i only select in recovery?
[Acer Iconia A500] meduza:
I think, you choose the active partition in the boot loader.

If you like to use linux as the second boot partition, I recomend you to look in the tegraowners forum unther a500/linux.

[Acer Iconia A500] Rippster:
My feedback to the V9 upgrade process...

I was not able to upgrade to V9 using the CWM method...it would error out in recovery.

I wanted to use blackthun3rs tool...but the download was NOT in .a500apk format.

-- I still used the tool and flashed bootloader.bin successfully.

-- Device booted fine.

-- what is the other file in the zip for? dlmodebl.bin?

I have V9 bootloader, TO's 1.8.1 Recovery, and TO's v13 ROM. Running great. However, since the upgrade, I've awoken in the morning to a dead tablet (meaning battery drain). Looking at my battery stat, usage was normal the first night, then dropped from 30% to 5% in about 10 minutes. Last night, went to bed with 70% left, woke up dead...it drained from 70% to 5% in 15 minutes. Not sure what's going on here.

I also did everything in Window 8 (for all the h8ters out there) :D

Not complaining. I think progress is awesome. Just giving feedback and if anyone knows the answer to my question.

Thank you!

M8 u can't be posting all over the place...when yr questions are not answered its becoz they've been answered many times before...perhaps u need to do some reading...threads are stickied b/c they contain info u need to know and almost ALWAYS (especially the a500 forums) that info is in the very first post...

but I'll tell u this for free,

u gotta dump and use yr OWN tabs bct...and pray u don't have the memory chip fault coz there aint no fix for that other than a new mobo
[Acer Iconia A500] dmpsuen:
Thanks for your advice, I did search extensively on this error but cannot find any solution. I just went mad and tried everywhere...my bad.

So do you think I cannot use others BCT dump on my A500?

When it said Bad Write BCT, what does it mean? Anybody else had similar issue?

Do you think Acer can fix it without changing mobo?

Sorry about that many threads and you are the only one that helps me, thanks very much.

Guys, please help me.

I have a A501, that bootloops no matter what rom is flashed.

I think the problem, that it cannot wipe the /data. Every time I'm trying it says "Error removing /data/misc/adb!"

I tried the power/volume+/orientation switch - but it doesn't work (i think because of custom bootloader i already flashed).

I tried flashing updated bootloaders and cwm but no luck.

What should I do? Tablet doesn't seem to be bricked, but somehow cannot boot the os(

Boot stucks

I got a similar problem.I have v9 for some weeks, everything worked fine. Yesterday I did a new flash and now I see bootloader v9 but it doesn´t continue to bootlogo.

After that I tried to flash with TWRP 2.1.3 ; 2.4.4 ; 2.6.3 and Thor 1.8.1 the result is everytime the same. Only once (i did same as other tries) it booted to system. but after reboot to install gapps I stucked again.

Anyone an idea to solve this? Also Re-flashed v9 via ZIP/Recovery
[Acer Iconia A500] ABAndi:
Problem solved

I did "format data" as described in this here: http://forum.tegraowners.com/viewtopic.php?f=8&t=83

I did this some times also with TWRP Recovery (format data) but no effect. This time I used Thor1.8.1 and choosed format /data

and /data/media after that I installed ROM via Recovery and now the A500 works again.

[Acer Iconia A500] RazzTick:
Have a problem here that keeps rearing it's ugly head. Sorry if this has been answered but after 3 days of searching I have not found anything.

When I first flash a rom after a fresh install of your boot loader everything is nice and fast. Boot time from power on to loaded Android OS is less than a minute. The problem comes from flashing another kernel.

I flashed civato's latest super charged ROM and everything is great. I then flashed godmachine's kernel and everything was working fine. The problem came after flashing ezterry's kernel. The tablet gets stuck on "Loading primary boot image from LNX" for a good 5 mins or more before it finally loads Android. Flashing godmachine's kernel did not fix the problem and neither did reflashing the ROM. I have run into this with v8 and v9 and the only thing that fixes it is using tdv4 or babsector. Thinking it was just a kernel problem I reflashed the bootloader and then flashed the ROM. After letting it settle for an hour or two I then flashed ezterry's kernel and it booted up nicely. After flashing godmachine's kernel I ran into the same problem as above where boot times were ridiculously high. Any ideas here?
[Acer Iconia A500] ad3qz:
I do have the same issue here.

After I upgraded the bootloader with Skrilax_CZ's bootloader V9, it always hang at BL screen showing Booting android image from LNX partition..., but nothing happened.

What's the problem?
[Acer Iconia A500] dibb_nz:
If you've flashed a kernel then ask in the kernel thread.

If u get this error by just running the patched boot loader then reflash it using the manual nvflash method.

If that doesn't work, you'll have to run the babsector file. Instructions and dl link in the root guide in my Sig.

You must use nvflash, auto tools won't help once you got this error

Here is a working link for the bootlogo tool, I dont have any of the other bootloader tool versions though. If I would have known that the Scrilax_CZ site would be gone I might have downloaded more of his tools. Hopefully the site will come back online, or maybe he will post a link to a new hosting site for all the stuff he has developed.

I have some request about teh file into bootloader V9 archive

Bootloader v9 archive content

In the archive there are theese file

bootloader_apx.bin

bootloader_v9.bin

bootloader_v9.blob

which is the use of this file

.blob - should be the logo file. Is it true?

.aspx.bin - should be teh file for APX_v0.4A-flashTool-500Manager. But should be have .aspx extension (not .aspx.bin)

.bin - which is teh sue of this?

I have an Iconia A500 rooted and I want to install your bootloader to load other mroe recnt ROM (like KitKat).

I want to laod your bootloader with APX_v0.4A-flashTool-500Manager but it laod aspx (not aspx.bin) file and Is tooped asking a confirm.

After I will load your bootloader I can use the tablet without additional backup/restore operation?

After your bootloader I will load CWM 6.0.4.5 aand I will make a backup.
[Acer Iconia A500] m27frogy:
bootloader_apx.bin - Main binary for flashing with nvflash.

bootloader_v9.bin - Not 100% sure what this is, it could be either a copy of the above file or the Honeycomb bootloader.

bootloader_v9.blob - fastboot partion file.

the apx.bin is NOT meant to be flashed with the manager, it's meant to be flashed with nvflash (manual flashing).

If you want to flash it using blackthund3r's tool, download the .a500apx file from here: link

No, you don't have to backup or do anything else, the tablet should boot up properly (although backing up with CWM is probably a good idea :p)

Hope that helped some!
[Acer Iconia A500] bovirus:
Thanks for the important info.

What do you think to add all theese info in first post (also with link for A500 manager)?

I believe that can help also other users!

I red the steps to update the tablet in various posts and this is should be this the right way

- Update original stock (I recovered the tablet from "boot verification failed" with update.zip with full ROM)

- Update bootloader (yours) to load future new ROM (my scope is to load OminiROM 4.4.4)

- Update CWM (6.0.4.5). I red tin relative post (http://xdaforums.com/showthread.php?t=2583710) that before to flash new CWM it's better to load the new bootloader (yours)

- Update ROM (OmniROM .4.4.4) via recovery.

If follow this guide I cannot make a backup (the original stock recovery don't have option for backup/restore) before to load your bootloader..

Do you think that I can update the recovery ovewriting the stock recovery as first step (befroe to load your bootloader) without problems?

Thanks
[Acer Iconia A500] m27frogy:
Woah there. I am not Skrillax_Cz!

Since I haven't seen him around here in a while, I'll try to help you as best I can.

You have the basic steps down although #1 should be optional (most people following this guide will already have stock android running OK). I may be wrong about this but I think that the stock bootloader will refuse to boot to a custom recovery so I'm afraid installing recovery before bootloader is impossible. However, if installing the bootloader (for a misc. reason) does not work properly, it will not effect your android version installed in the slightest. Once you have the bootloader fixed again ICS will boot up again like nothing happened.

If you have anymore questions, ask away. ;)

hey, I have installed on my a500 your v9 bootloader, but I wanna back to stock acer and install bootloader stock....how can I do it? I just flashed now a 4.0.3 stock acer, but im still on v9 BL.....

somebody can help me? :confused:
[Acer Iconia A500] m27frogy:
If you do want to go back to standard bootloader :crying: it should be pretty easy. Here's a post that I've used several times to get back to stock (assuming you have working custom recovery :cool:). Grab one of the official full ROMS (which should include bootloader) and flash it in CWM. Don't use the 4.0 leaked versions, my advice would be to flash the HC bootloader then use the official OTA updates to get to the latest version (4.0.3 I think).

Still tho, makes me wonder why you want stock back with how good Skrillax's BL is and how computer literate you have to be to get it to work. Are you reselling it or do you just like bloatware? :p
[Acer Iconia A500] Joshbone:
It has started going slow and I want to restore to factory for myself....

Only flashing a stock HC with cwm will erase the Skrilax BL? Which version you recommend me exactly?

Thanx ;)
[Acer Iconia A500] m27frogy:
I believe just flashing the full HC will do it. I would recommend flashing the oldest full english HC you can find there, assuming you are in 'Murica. Personally, I would flash Acer_A500_4.010.38_COM_GEN1. That should, I believe, include both the bootloader, recovery, and ROM. Hope it goes well! :)
[Acer Iconia A500] Joshbone:
Not work! :confused: I boot Recovery Partition from bootloader and wipe all, after that, I have flashed the rom and reboot, but Skrilax bootloader still there......

Hi there,

I am having a hard time with my liberty tab (same as iconia a500) since about a week.

When the problems began, I only couldnt boot to android. Then after trying to patch v8 to v9, I made a mistake and tablet was only starting in APX mode. I recovered my tab thanks to the unbrick a500 thread here at xda. The rooted Honeycomb which was installed during the "unbricking" was running without any problems.

Now I tried to flash again the bootloader, the cwm and one ROM of civato, but after flashing I end up on the bootscreen.

Can someone help me? I am just one step away from throwing the tablet down on the street....

Thanks in advance

darius

Edit: I tried the Shellshock ROM, the Re-Flexx Ressurrection and the CM10 Version (all ROMS made from or made with civato).

After flashing the Skrilax bootloader v8 and Thor 1.7.3, Honeycomb was running still fine.

After flashing a ROM via Thor 1.7.3. the Tablet is hanging on "Booting primary kernel image" screen.
