[Q] which bootloader do i have... - Acer Iconia A500

Any easy way to tell?

IF you never update it, I'd say HC (older 1)..If you ever updated to ICS thru OTA update (then you'd have ICS LOCKED Bootloader.
You'd have to manually add ICS UNLOCKED Bootloader to have it.. IF you flashed roms in old days of HC, then u might have UNLOCKED HC Bootloader.
When I load up my tablet that i added it myself, it says Skrilax Cz's bootloader (it is ICS UNLOCKED Bootloader.)
you can run a few programs will tell as well...
Google this... Acer A500 Afterota Lite v1.09 (after running. it will say something like , do you want to save file..it saves info to a .txt file and will say.
maybe this... Acer A500 Manager 1.1 (blackthund3r)

Make sure there is no sd card in the slot.
1. Hold the tablet in landscape.
2. Make sure the switch next to the volume is at the left position.
3. Hold volume up (right side)
4. Push and hold power for 3 seconds while still holding the volume button from step 3
5. After releasing power and still holding volume, a soon as the tablet vibrates, quickly switch the switch next to the volume rocker back and forth.
6. If you did it right, it will show you the bootloader version number
Good luck

Downgrade ASUS transformer (No root required)

Vietnamese here: http://bit.ly/iA3KEp
For some reason, (the latest 8.2.3.9 OTA difficult for rooting, and some case update the BLOB V5 casue the Sleep Of Death) or just because you love the Custom Rom that using 8.2.2.6?. Beside of that, this is a good practice for you guys for doing homework hehehe: how to enter recovery, how to wipe data, etc...
Here it is:
- Status before downgrade: no ROOT with some of the newer updates from ASUS such as: 8.2.3.6 or 8.2.3.9...
- Find away to copy this file to your SD CARD (/removable/MicroSD - the external one not the 16GB inside): http://bit.ly/kJJijy (Rename it to EP101_SDUPDATE.zip)
- Power Off
- Press Volume-down and power at the same time for around 10sec
- when the small white msg (on the top left corner) say sth about Recovery appear press the Volume-up then our tablet will automatically do the downgrade itself, when done it'll reboot (using the combo Power + Volume-down and then Volume-down again for wipe all DATA if you can not pass the ASUS LOGO around 10' - but in most case your tablet can boot directly to Android without Wipe Data (lost all of your settings and apps))
- Status now: 8.2.2.6 no ROOT!
- Wanna ROOT and using the latest 8.2.3.9 Custom rom? Here we go:
(this is not working on my ASUS transformer, i think its the wrong file's inside)

flashing PC10IMG with no power button?

ok one last quick question, the power lock button is currently dead on my phone and im currently redowngrading from a return to htc (refused due to liquid apparently) now the guide calls for me to install the pc10img by using adb reboot bootloader, but buttons are totally unresponsive in that state (even the volume ones which do work) however if i hold down the volume down button when i pop the battery back in it scans the card and finds and checks the pc10img fine and lists a load of stuff and asks me if i want to update, the only thing that concerns me slightly is that it says HBOOT rather than bootloader at the top, is it safe for me to say yes?
hboot indicates your Bootloader version.
So thats the place where you have to load the PC10IMG.zip's
Best and good luck,

APX MODE?

So I'm trying to downgrade my tablet back to 3.2.1 from the ICS leak so i can have custom recovery again. and I've tried to get it into APX mode 5million times! I'm beginning to think I'm stupid! please help!
This is what I'm following
1. Turn off the ICONIA TAB by long pressing the power button for 5 seconds.
2. Use a paperclip to push the reset button, don't release it.
3. Press the power button for 3 seconds.
4. Release the power button
5. Wait for 1 sec and take out the paperclip.
LOL just got it after posting this Sorry and me being a newb to the forum I don't know how to delete it!
If you need to use APX anyway, then why not just flash modified ICS bootloader, which allows you to flash anything you want? Why go back to HC bootloader just for that? All the new ROMs will stop supporting HC bootloader eventually.

[Solved-Q] Must be a moron, but I just can't get vol+/power-button to CWM-R to work

This is a painful message to write, but I am desparate. This should be so simple!
Have a U8800 standard (at least it says only "U8800" in settings/about phone.
What have I done:
- Upgraded some time ago to 2.3.5 Rev B522 from Huawei.
- Then rooted it with SuperOneClick.
- Installed ClockWorkMod from Play Store.
- Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.
- Turned off Fast boot under settings/applications
:: What worked/happened.
- Rooting went fine, ES file explorer and others get root-permissions ok.
- But got into CWMRecovery only via CWM program (Choosing "Reboot into recovery"). Never with the holding buttons vol+ and power-button during power-on.
Figured it was that locked bootloader on B522 that was the problem.
What I did:
- Followed the instructions in http://forum.xda-developers.com/showthread.php?t=1457490 (Get your pink screen back).
- In CWM Recovery flashed "update-B518-bootloader.zip".
- Got "ok installed or something to that effect" from CWM Recovery.
:: What worked/happened.
- Still could not get into CWMRecovery via button-holding. Tried reflashing the B518 bootloader a few times, but just no difference.
Read somewhere that each Huawei firmware-release comes with it's own bootloader, so lets try to install Huawei B518.
- Only place I could find the image was here http://huaweiideosx5.blogspot.no/2012/03/u8800-b518-23-software.html
- U8800V100R001C00B518G001.zip
- Had to take out the external SD-card to get the /sdcard/dload directory on the internal SD-card.
-Seems to be important to have dload on the internal SD-card and not the external.
- Booting the phone with vol+, vol-, power did not start the downgrade, but was able to trigger it via settings/storage/software upgrade.
After downgrade to B518 (Checked version in settings/about phone):
- Deleted /sdcard/dload directory.
- Rooted with SuperOneClick
- Installed ClockWorkMod from play store again.
- Put CWM Recovery 5.5.0.4 into ./cust_backup/image again (think this was unecessary. I think it was already there but did it anyways)
- Turned off Fast boot under settings/applications.
:: What worked/happened.
- The phone is now in B518 software, but still can not get into CWM Recovery via keypressing at boot.
I hold the vol+ and power-buttons all the way to "desktop" so to say, but can not for the life of me get into CWM Recovery that way. Getting into CWM recovery 5.5.0.4 via instructing CWM application to boot into recovery works fine, though.
I am drooling at the thought of ICS Aurora, but I don't dare before I can reliably get into CWM Recovery via keypress.
Sorry if this is very stupid post, but I have tried so much.
Maybe the volume buttons are faulty? Turn off the phone and try this: hold down volume up; while holding press power button as long as the logo comes up. Release power button but continue holding volume up. If it did not work, try doing same with volume down.
Yeah, do what Blefish advised you but do it while the phone is off and charging. I have a kinda broken power key and with this 'trick' it boots faster and more reliable. Keep holding the 3 buttons until you see the recovery.

Thank you both for trying to help me here!
Unfortunately I have had no luck with your suggestions.
Re: Broken keys.
Power and volume-buttons seems to work well when the phone is on. Also when I boot into recovery through the CWM program, navigate to advanced/key-test, the vol+, vol- and power button seems to work well there too.
On pressing the power-button, CWM-R reports Key: 116
On pressing the vol+-button, CWM-R reports Key: 115
On pressing the vol--button, CWM-R reports Key: 114
So I think the keys must be ok, right?
Blefish: I did what you suggested, as I understood it.
When the phone boots, there are three stages of logos.
1. A static logo of Huawei's red "fan?".
2. A short "comet" animation.
3. An animated logo of Huawei's "fan", where some highlight flashes from left to right over the fan.
I hold the power-button in until I see the first static logo, then let go of the power-button and hold the volume-key(s).
Is this the same stage in the boot-process that you were thinking of?
I have tried vol+, vol- and both vol+ and vol-, together with releasing the power-button at that point.
Have not had any success with that, and ended on the "desktop" each time.
AceDroidX: I tried your suggestion as well.
I did this:
1. Shut down the telephone
2. Plugged in the power.
3. A "fan"-logo appears which is replaced by an animated battery.
4. Upon seeing the animated battery, I tried the various key-hold variants.
- vol+ and power : Ended up at desktop.
- vol- and power : Ended up at desktop.
- vol+ and vol- and power : Ended up at desktop.
So not much success either.
I am out of ideas... Can it be that B522 bootloader that still lingers in there, not replaced by installing the B518 software?
Well, idk what else to suggest.. Maybe your problem is here?
Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.

I remember that when i mount my phone in linux, there was a partition with just the image folder. Some files like boot.img and recovery.img where there. Try to put the recovery image in there and see if it makes any difference.
I'd like see your versioninfo, can you upload a screenshot?
You can check mine from B528
AceDroidX: When I use Remount, I am able to mount that partition as read/write so that I can copy CWM's Recovery image in there. I think it is identical as mounting it up remotely, as you do. I am after all able to boot into CWM-Recovery, just not by key-pressing? I suppose I could boot into Linux and try to mount up the partitions as you do.
Hi kilroystyx: I can not figure out where to find a similar-looking page as the one you have in your picture.
I have the settings/about phone, if that is an older version of what you have there?

Based on the screenshots your installation is fine.
Just one last shoot based on what AceDroidX says, with phone off press Vol+ and hold then connect USB cable to PC or charger and stay holding Vol+ then wait...wait and what you see?
hi all,
i'm using some ics roms and it seems ics supports natively vol++power button to take screenshots but it doesnt work for me... do you know if there are some custom ics rom where it will work?
thank you
Wow.. It is hard to believe.. but I have actually ... eventually found a way to get into that CWM-Recovery every time.
It is a combination of your suggestions.
I have been doing variations, trying to figure something out and eventually there is a method.
What I must do, on this phone, in order to get into CWM-R is this:
1. If the charging cable is in, then unplug first.
2. Turn the phone off.
3. Take out the battery and put it back in.
- This makes a difference on my phone, at least. I am not able to get into CWM-R wihtout taking the battery out first.
4. Press and hold Vol+
5. With Vol+ being pressed continously, insert the charging-cable.
6. Wait for the Fan-animation to finish and the "battery-charging" animation to start.
7. When the battery-charging animation is running and the screen eventually goes black, keep holding the Vol+ button for some time.
- Sometimes it works to keep holding the Vol+ button for only a second or two. Sometimes I must hold it up to 30 seconds.
7. Press and hold the power-button in addition to the Vol+
8. Wait for CWM-Recovery to start.
Thank you very much for your help.
Now I think I can try for ICS!

Try Vol- and Power ON

[Q] safe mode,getting to fastboot, and returning to stock

I'm having reral trouble gettng my n4 into fastboot. all the buttons work, vol up, vol down and the power on all work fine but if I try and press all 3 simultaneously I just boot the device normally. I've managed to get to fast boot just once in 2 dozen tries. what is the trick? I've tried pushing all 3 at once, I've tied pressing both vol up and down, holding thm, then pressing and holding the power button too. always just vibrates, and boots normally.
just now while trying on the last attempt it booted normally but the screen had 'safe mode' in the bottom left corner. that freaked me a bit. turned it off, then on again and it went away. wtf is 'safe mode' and how did I get it?
I want to...I think...root and flash a rom the proper way, step by step using efrant's guide on here, rather than a script from the toolkit, but since I can't seem to get to fastboot I'm stuck
this is all just to get to 4.3 really....I rooted using the toolkit and OTA updates haven't been running so still on 4.2.1 and thought I should sort that out. had a bit of a 'mare l2 nights agot when I unlocked the bootloader to go about returning to stock and forgot that would wipe the device...losing lat weeks holiday photos in the process I think the tool kit and one press type 'unlock, flash this, flash that etc etc' commands lulled me into not thinking for myself so perhaps I ought to do this properly!
BTW, I'm currently with a locked bootloader, stock 4.2.1 rom, stock recovery reflashed, no su binary (cinfirmed by attempting to run SU app, and it not finding the binary). I've been waiting for the OTA update to push to the device again (I've forced checkins but to no avail) to attempt to run it, should it run properly now or have I to do something more?
You need to hold power and volume down, if that doesn't work then try adb reboot boot loader

thanks. tried holding volume down and then also power as well and again it booted normally. looks like adb commands it is then. bit of a pain to have to hook to a pc to do this....not that I'm a regular custom rom flasher/swapping between roms and nandroid backups etc but it would be handy....I learnt that with my old desire.
has anyone else had problems getting there holding the buttons?
oh and I found what safe mode is from the google nexus 4 site. a mode where the apps don't work so you can check for problems that they may be causing. how I got to it doesn't match with the descried way though...just a weird glitch I guess.
okay I'm all sorted for now. I used the toolkit and flashed the entire set of stock .img after downloading the archive from google
now on 4.3, and as far as I can see that is with stock recovery, system, radio the lot. I've left it unrooted (so no su binary, no busy box, no su app - although the phone is currently synching and downloading my apps again..I guess this will come too) so if I understand things correctly future OTAs will run.
I've left the bootloader unlocked as efrant, in his 'how to' guide says
'Do NOT re-lock your bootloader after you are finished. The is no need. 2) Having an unlocked bootloader does not affect anything related to the ROM/GoogleWallet/OTAs. Nothing at all.' and he explains that unlocking in the future to enable fastboot commands to work and hence flash roms in the future results in a wipe of data. So...I think...I'm up to date, stock, safe and future OTAs will run....i hope. I do understand though, that should the device need to back to Google I should relock the bootloader first or they will know I've been playing around (where possibly I shouldn't!)
okay....think I can go ahead and set up again. :victory:
Ooo good! and whatever I've done I can get into the bootloader fine now :victory: simply holding vol down and then pressing and holding the power button now works every time. good.
