[Acer Iconia Tab A100] cancuuun:
Can't get fastboot unlock (icons does not appear)

My issue is that recently my Iconia A100 got an update from google play (just as usual updates) and then suddenly rebooted, I thought it was "normal" because a mayor update... but after a few minutes I saw it didn't start... (just Acer white logo)

Then I found some forums to start in recovery mode (power btn + Volume UP)... A little green android appears with the red warning on the chest. When I touch the "home button" Appears "Android System Recovery <3e>" with the android system recovery utility options.. under those options (in blue color) there are a lot of errors (in yellow) mentioning about " E:Can't mount/cache" or "(No such file or directory)"...

So I found out the command: fastboot flash recovery [path to TWRP recovery img]

but I found my fastboot is locket

"Bootloader vo.03.13-ICS: Starting Fastboot USB dowload protocol

Fastboot: Not supporting command in Lock mode

Failed to process command download: 004c1800 error(0x2)"

So I wanted to unlock it to restore it, but all tutorials I have found ask for the tablet working to execute "fastboot oem unlock" from the console

My problem is that I can't start the operating system...=(

Only I can start "Bootloader vo.03.13-ICS: Starting Fastboot USB dowload protocol" (power btn + volume up, then move the rotate btn back and fwd) and when I try typing in console the commands: "adb" then "fastboot oem unlock" NOTHING HAPPENS, just the screen loads Acer white logo (in the top left corner keep saying "Bootloader vo.03.13-ICS: Starting Fastboot USB dowload protocol") and stay there... not showing any icons, no messages, no errors, nothing...

Does anyone know hoy to unlock fastboot WITHOUT having the tablet working?

NOTE:Previous to the brick issue, my tablet had ICS and was rooted and was working without problems.

---------- Post added at 01:42 PM ---------- Previous post was at 01:17 PM ----------

My tablet (Iconia Tab A100) issue is that Android does not start (after a google play update)

I read the comments and I have all files requested, and my tablet connected to the computer (win7 x86) with previous preparations done... but when I run "install-eng.bat" from the command console say this:

" Wait for connecting device

adb server is out of date. killing...

* daemon started succesfully * "

And THAT'S ALL!! nothing happens :rolleyes:

Just to know, when I try the command "adb devices" it does not show any device (even in my computer does not appear any device connected)

When I try sending commands like "fastboot update..." it says it's locked (there is communication) but that's why I wanted to unlock fastboot inicially

Any ideas?
[Acer Iconia Tab A100] Romman0:
You can't restore unless you created a backup with a custom recovery.

I would get the Stock Rom official ICS from the dev section, from Zeronull. Rename it update.zip, put it on your microSD card, and then boot to the stock recovery. You were getting the dead android because there was no update.zip on the sd card to load.
[Acer Iconia Tab A100] JohnnyDanger:
Hello all. Can anyone guide me in the right direction? I finally decided to unlock my bootloader on my A100. When I run the install-eng.bat file under administrator a command prompt pops up really quick then disappears. So quick I cant tell what it says. Im using Windows 8 and dont know if that might be the issue. Can any provide any recommendations?
[Acer Iconia Tab A100] Theonew:
Run it normally (not as Administrator).
[Acer Iconia Tab A100] JohnnyDanger:
Tried that too and nothing. Actually, I got a little further. Appearently something was wrong with my SDK cause I downloaded it again and not it brings up a command prompt and says the following:

Any other suggestions
[Acer Iconia Tab A100] captain.johnshepard:
Try reinstalling your Acer usb driver. I was having the same problem last night. I had to go into device manager and uninstall the Acer a100 and re download it from their site. I was using win7 though. Good luck.
[Acer Iconia Tab A100] pio_masaki:
Also it sometimes helps to not open it right on the file but open a prompt then cd to it's directory then run it that way. I stops the instant open and close thing.
[Acer Iconia Tab A100] JohnnyDanger:
Thanks, I will try that.
[Acer Iconia Tab A100] JohnnyDanger:
No luck. I think Im going to pull out an old XP machine I have and see if I can get it working on that.
[Acer Iconia Tab A100] Romman0:
Make sure your extracting the zip and running the install.bat (just double clicking) in the extracted directory that has fastboot and adb in it.
[Acer Iconia Tab A100] JohnnyDanger:
Yeah, thats what Im doing. No luck though. I really think its an issue with Windows 8 talking to the tablet. I remember I had trouble with rooting recently and took my tablet to a friends house and it worked fine on his XP computer.

---------- Post added at 02:21 PM ---------- Previous post was at 01:23 PM ----------

Ok, so I got the computer to recognize the tablet but after it restarts and goes into fastboot it almost instantly saysd

Any recommendations on how to get past that? Oh and Ive tried it at least 50 times and cant get it to work. I know earlier posts say to press down then up volume right when the screen changes, but that didnt work for me.
[Acer Iconia Tab A100] pio_masaki:
Speed is the name of the game on that one. It may also say that if the a200 bootloader isn't actually there, maybe verify the bootloader version too.
[Desire HD Q&A, Help & Troubleshooting] kmkzboi:
Hey guys,

I did a DIY screen replacement on my DHD, only problem was that I kind of made a mess of the housing (the gap between the housing and the screen, it's loose so when i put my phon all back together the screen keeps falling out. I previously used sticky tape over the phone (LOL, looks pretty nomad), removed it and then screen falls out non stop, I was wondering what type of glue I would need to fix the housing into place, my screen is loose and constantly unplugs alot, so as of right now i'm using the androindscreencast java app on my pc to even use my phone, (since my screen still works but I always need to disassemble my phone to plug in the screen cable), so all I can do at the moment is just look at my screen. All I want to know is how I would sticky the inside so it wont let the screen fall out.

All help is much appreciated!
[Desire HD Q&A, Help & Troubleshooting] Hunt3r.j2:
It needs to be pretty sticky, seeing as how part of taking the screen apart requires you to use a heat gun to loosen the adhesive.
[Desire HD Q&A, Help & Troubleshooting] yamFZ6:
you need double sided adhesive tape.

[Defy Q&A, Help & Troubleshooting] Hmetool:
I've just tried upgrading to ICS and failed. Apparently I flashed the wrong kernel - should have flashed the CM7 one, but flashed the CM9.

Now my Defy is stuck on the Google logo and I don't know how to reach recovery mode. Pressing Power+voldown does nothing. Power+volup gives me the bootloader, which asks me to connect a usb cable, but I have no idea what to do after that.

I have two Nandroid backups: one stock (2.2) and another with CM7 (2.3.7). My Defy has a green lens.

Is there any way to restore my phone to one of those backups?

Thanks in advance
[Defy Q&A, Help & Troubleshooting] fiskenigaten:
Do you still see the blue led for custom recovery?
[Defy Q&A, Help & Troubleshooting] rperdue5:
You will need to flash a new SBF with RSD lite

follow instructions in this thread

How to flash new SBF
[Defy Q&A, Help & Troubleshooting] Auris 1.6 vvt-i:
Do not flash any sbf's. Reboot the phone, at the blue led press Vol- and when you get into boot menu, flash the correct kernel. If you flashed Defy build, flash CM7 (Froyo) kernel. If you flashed the Defy+ build, flash CM9 (Bingerbread) kernel.
[Defy Q&A, Help & Troubleshooting] Hmetool:
I see the blue led, but it goes on to green regardless of what I do (power+voldown does nothing). I've tried to access recovery mode several times, but the phone doesn't respond. Maybe I'm doing something wrong.

I've read the guide, but my original SBF is missing ever since MegaUpload's demise. Is it possible to use the Nandroid backup instead?
[Defy Q&A, Help & Troubleshooting] Hmetool:
Ok, apparently I wasn't pressing the button at the right time. Recovery mode is now working. However, I don't have the correct kernel in my SD card - only the wrong one.

My Nandroid backup seems not to be working too, apparently. I went into recovery and restored it, but boot still doesn't work. I wiped data/cache/dalvik cache and tried again, but it still didn't work. I'm at a loss here.

Should I try to flash some other sbf, since I can't find my phone's stock one?
[Defy Q&A, Help & Troubleshooting] arpith.fbi:
go to ICS thread and on the first post there is a link to signed CM7 kernel zip..copy it to ur sd card and flash it..
[Defy Q&A, Help & Troubleshooting] Hmetool:
I just tried installing the zip from the sdcard, but I got an error message: "Can't make /tmp/update_binary. Installation aborted". It seems that I can't install any zip now.

Is there any way out of that? I'd be more than happy if I could just flash my nandroid backup, even if that means being stuck without ICS for a bit more time.

I'm on ClockworkMod Recovery v2.5.1.8, if that helps.
[Defy Q&A, Help & Troubleshooting] pranks1989:
Hi,

I faced a similar issue but it was since I flashed CM9 for Defy in my Defy+ with 2.3.6(stock) ! Nothing was working and I would get some boot errors! I rectified it by flashing full SBF and then rooting. Well if you want I can provide you with the SBF I have but it is for 2.3.6 and so you will loose downgradability. I have 4.5.1-134-DFP-1321 - retail-asia full Blur multilanguage with me. However, you can also give Walter's fixed SBF and Nandroid backup a try
[Defy Q&A, Help & Troubleshooting] Hmetool:
Thanks, it turns out that flashing a sbf was a nice way out of this mess. I flashed a 2.2.2 which is almost identical to my stock rom (couldn't find that one).

If I root my phone now, can I still try to restore my nandroid backup? Or should I just skip that and try flashing ICS again?

My SD card has the 03-19 CM9 Nightly, gapps and both CM9 and CM7 signed kernels. Should that suffice? CM7 kernel is the right one for green lens defy, right?
[Defy Q&A, Help & Troubleshooting] Auris 1.6 vvt-i:
If you are on a green lensed Defy, then yes - flash CM7 signed kernel and one of the Froyo bulds of Quarx or Epsylon3 - try them all if you wish and see which one you like the most.

Procedure is easy:

1. Full wipe

2. Flash CM7 kernel

3. Flash ROM

4. Flash gapps

5. Full Wipe

6. Reboot

When you decide to try a new ROM, there is no need to flash the kernel again, just wipe, flash the new ROM and gapps and then wipe again.
[Defy Q&A, Help & Troubleshooting] Hmetool:
Thanks, that's great. Are all regular Defy roms Froyo builds unless stated otherwise? I couldn't find that info on the files I have.

One question: by full wipe you mean data/cache/dalvik cache or is there anything else that I'm missing?
[Defy Q&A, Help & Troubleshooting] Auris 1.6 vvt-i:
Yes, "Defy build" means Froyo kernel based, "Defy+ build" means GB kernel based.

Exactly.
[Defy Q&A, Help & Troubleshooting] pranks1989:
Yep, that's exactly what it is..
[Defy Q&A, Help & Troubleshooting] Hmetool:
I've just rooted my phone again, followed the steps and installed CM9. It worked like a charm. I was pleasantly surprised at how smoothly it runs, didn't expect that sort of quality from a Nightly. Awesome.

Thanks a lot for saving my phone, guys.
[Defy Q&A, Help & Troubleshooting] pranks1989:
Sounds great :) Well since CM9 nightly is still a long way to go, you may want to dual boot CM7 and CM9. Install CM7 as primary and dual boot to CM9.

Im looking for a good micro SD reader/write so I dont need to constantly shut my Phone down to take the MicroSD card out & move/delete files..

Also, the charging cord that came with my phone only works when my phone is upside down..lol it seems its the pin that goes into the phone that is messed up. Is there any place I can get just the cord that is reliable?
[EVO 4G Accessories] oOflyeyesOo:
There are a few apps that you can manage your phone files wirelessly, what is it, airdroid I think. Im sure there are others.

It could be the cord, thats what I thought at first and some cords did charge my phone, but in time my charging port would not work at all no matter how hard I tried to angle the cord and put the right amount of pressure. Its nice to have a external battery wall charger now, be good for you if the case is your port is becoming loose, would be better to not wear it out more for the time you may really need to plug it in to charge with a cable.
[EVO 4G Accessories] Pivo187:
I am 100% its the cord bc I used the cord from my sis HTC EVO Shift & it works 100%. Fly which wall charger do you use? Is it 100% reliable? Ive been reading on amazon & it seems everything is basically hit or miss....I just came across this: http://www.amazon.com/Seidio-Multi-...er-Incredible/dp/B003N1915S/ref=cm_cr_pr_pb_i

It comes with a brand new cord plus a charger that can both charge a separate battery & the phone/battery at the same time. Im not sure if it can also charge higher capacity batt like 3500..Anyways do you happen to know where I can find a good miCroSD reader/write too? Kinda leaning to order it all on amazon to save on shipping.
[EVO 4G Accessories] Pivo187:
Bumpp anyone??!
[EVO 4G Accessories] oOflyeyesOo:
Thats a expensive battery charger. Id just go grab those two 1700 ankers with the charger for 16 bucks on amazon.

And by microsd reader/writer, you mean a external device where you can pop in your sd card in to manage your files? I don't know much about those, as my computer and laptops have had them built into the case the past 5 years, im sure ebay or amazon will have some cheap ones all over.

hmmm... u mean the stock wifi modules package? or my kernel's wifi modules?

also post output of this:

[Sony Xperia S, Acro S, Ion] Knight77:
Guys I'm sorry I read this topic and the recovery one, but about some things I'm quite confused, so I'll repeat what I got and tell me if I'm right or wrong...

TO HAVE ROOT

- I have to install the DooMKernel

- To install the DooMKernel I

have to

unlock the bootloader

- To unlock the Bootloader the easiest way is to follow what is written in the fist post of "Tutorial] Xperia S Bootloader Unlocking & Relocking"

THEN

- If I want to install a rom the only way is to use the Recovery by DooMLoRD that is based on CWM and compatible with Rom Manager

- There is no other way of doing this.

So, last point, the classic "Root modus operandi" that I had on SGS and SGS II like one click or just flashing a "rooted kernel" via pc utility is not yet avaiable, right?

Thank you very much.
[Sony Xperia S, Acro S, Ion] DooMLoRD:
there is no known exploit which works to root the Xperia S...

to get root u can either flash a pre-rooted system.img or flash a kernel which will do the rooting for u (e.g this kernel)...

to flash any kernel/system.img u need to unlock bootloader.... read unlock bootloader thread....
[Sony Xperia S, Acro S, Ion] 4lex96:
