[Q] [A700] bootloader unlocked, but nathing happens with fastboot flash - Acer Iconia A700 and A510

I unlocked the bootloader by doing:
Code:
# adb reboot-bootloader
// wait for it to reboot
# fastboot oem unlock
// follow the on-screen instruction to unlock the bootloader by pressing vol-up then vol-down
# fastboot reboot-bootloader
and now it boots with "Bootloader vICS-MR1-a055314(UnlockMode): Starting Fastboot USB download protocol" on the top left corner.
but then I try to flash recovery downloaded from this thread by issuing:
Code:
# fastboot flash recovery recovery-a700-6015.img
sending 'recovery' (5006 KB)...
OKAY [ 1.985s]
writing 'recovery'...
OKAY [ 2.601s]
finished. total time: 4.586s
// the screen flickers (going to pure black with backlight and come back in ~0.1 sec).
# fastboot reboot
# adb wait-for-device
# adb reboot recovery
but it's still the stock recovery (with an android with belly opened in the middle).
I tried all images (6.0.1.5, 6.0.1.4, 6.0.1.1 update 1) in that thread but none of them works.
I also tried to boot the recovery image (works on my HTC Desire) directly by doing:
Code:
# fastboot boot recovery-a700-6015.img
but the screen just flickers once and nothing else happens.
I tried to unlock the device again by issuing "fastboot oem unlock" once more, but it says the device is already unlocked.
I also tried another USB cable but didn't help.
What am I doing wrong (or missing)?
=== UPDATE: 2012/11/14 ===
this problem is solved by the OTA update "Acer_AV051_A700_RV19RC01_TWN_GEN1 (Acer_AV051_A700_1.054.00_TWN_GEN1)".
the bootloader is vJB-653b3d3 now.
I think it's just a problem with certain version of the bootloader.
so you may want to either upgrade or downgrade your ROM version and try again.
btw, sorry for my bad English, I'm not a native speaker.

Same Problem here, did you get a solution already?
or anyone else?

Are you using the a700 USB drivers from the HTC support site, this did help me a while back, I had similar issues.

No I use the one from Acer of course. But I will give it a try. I pray that it works. Lol
hmm, don´t find anything that sounds like what I need.. Can you give me a link? would be grateful

I'm on Linux so there's no vendor drivers required.
I received a OTA yesterday, and the bootloader is now vJB-653b3d3.
the unlocking process worked on this version without no problem.
It might just be a random failure I guess......

Problem Solved.
My Solution was to flash the Recovery into boot-section by typing "Fastboot flash boot recovery.img"
So i was able to get into Recovery and install a FR_Rom
Special Thx to meier2009 from the german Forum Android-Hilfe.de

that would be a weird method.
you can't flash recovery partition but okay with boot partition?

Yes, Don´t know why, but this works for me...
any other methods failed.
don´t matter, i´m Happy again

Cant boot into recovery...HTC screen only

I attempted to place a ROM on the phone using CWM recovery and something messed up. Now, I can boot into screen that says fastboot, recovery, etc. However, when I select recovery, nothing happens. Anyone point me in the right direction...im back to using my Blackberry!
From fastboot try and reflash recovery I would highly suggest twrp over cwm since twrp officially supports the one x.

This is where I am stuck. Unfortunately, I'm not all that familiar with Fastboot. When connecting the phone to the PC with a USB, I see that the phone says Fatboot USB. From there I'm lost. I've not been able to find a guide that describes how to install a ROM using fastboot. Lots of posts says that it can be done, but none describing how its done. Anyone pointing me in the right direction?

My Bad...didnt have the img file in the platform-tools folder.
So I've tried flashing the TRWP img and when I reboot into recover, I get the blue and black Teamwin splash screen. then it reboots and stays permanently on the HTC splash screen.
After I flash the clockwork img file and reboot into recovery, it reboots and stays permanetly on the HTC splash screen.

Sounds like a bad flash or corrupt recovery inage. Go to the play store and download goo manager and install twrp from goo manager instead. See if that fixes the problem.

It's just an exe. Boot your phone into fastboot mode. Your computer will recognize that it is plugged in in fast boot mode if you have the HTC driver installed. Then open the exe on your computer and follow the instructions on the screen. It will take about 15 mins for the whole process and your phone will reboot several times.
Also make sure you use twrp recovery instead of clockwork if you re-root!

I cant seem to find a stock Rogers Ruu...will continue searching. Anyone out there have it?
http://http://forum.xda-developers.com/showthread.php?p=27882810#post27882810
Finally got it working...the above link is what worked. Here is the summary...
I was having this same problem and it took a while before I could get it to work. Try opening a command window in the same location of your adb tools.
First, make sure you're in fastboot mode, then type 'fastboot oem rebootRUU'
Next, make sure you have the .zip RUU file in the same folder and type 'fastboot flash zip XXX.zip' (replace XXX with whatever it's called, of course)
Now, you can see what is actually happening when you are flashing the RUU. In my case, there was 2 points where it told me to "re-flush image immediately" or something like that. When I ran the last command again (fastboot flash zip XXX.zip) it went a bit further each try, but it took until the 3rd try before it was successful.
Hopefully this helps you out!

do this:
1.Put Rogers stock zip (keep it in zip form) in your platform-tools folder (you need to download Android SDK). This is the rogers file I downloaded...http://rapidlibrary.com/files/pj83i...elease-254934-signed-zip_ulc8eyefx8i89on.html
2. Boot phone into fastboot (hold power button and volume down key)
3. Used command window to relock bootloader by doing the following:
use command window to get to location on your computer where you have saved SDK stuff, continue with command window to the platform-tools folder then enter the following commands:
fastboot devices <enter>
fastboot oem lock <enter>
Phone will restart and reboot into fastboot again
4. type 'fastboot oem rebootRUU'.
5. Next, make sure you have the .zip RUU file in the same folder (see step 1) and type 'fastboot flash zip XXX.zip' (replace XXX with whatever the rogers stock zip is called, I changed it to "rogersstock.zip")
Phone will reboot to a HTC screen. If you see "re-flush image immediately", repeat fastboot flash zip XXX.zip command. You may have to do this 2 or 3 times.
After doing this, I was able to download and install the Rogers firmware update
BTW...I didn't discover any of this stuff on my own...I researched a bunch of different posts and put it together. Hopefully, someone else finds have all this in one post useful.

What you are doing wrong is flashing the recovery for the wrong phone. Any file with "enveavoru" in it is for the international (Tegra3) version. Our phone is "evita".
Only install things in our Dev forum:

To see everything in an organized list, go to my index: http://forum.xda-developers.com/showthread.php?t=1671237
Also, TWRP is recommended. CWM does not officially support our device, and therefore is just a port, and buggy. TWRP officially supports our device.

Please advise... Thanks.
If your running windows, just make sure all you files are in the same folder ie twrp, adb, fast boot then press shift + right click, open command prompt here. I've heard of have you virus protection on? can cause problems.

Yes, adb.exe - fastboot.exe - AdbWinApi.dll and the twrp recovery image are all in the same folder.
My only other suggestions would be to make sure you have administrative permission s on you PC. I can't imagine why its doing that to you unless you downloaded a corrupt boot image. I've had that happen a few times.

Is there anyway configurations prior to running Goo Manager? I have an unlocked bootloader, not sure what else is missing for it to not restart on it's own after downloading and 'installing'. Did the same thing happen for you?
Also note my phone is not rooted (stuck on Rogers' 1.94.x.x firmware after the OTA) -- could this be a problem? If so, how do I root my device otherwise..?

Which tool are you referring to? I cannot find it. Any one click tool I see does not work for 1.94.x.x firmware...
I was on 1.94 too.
Just try goomanager again, download twrp, then in goomanager go to options and install open recovery.
Might want to make sure fastboot is off in options too before tryin to boot into recovery.
If that don't work its beyond me sorry.

Yeah, I found it a few minutes ago as well. I gave up though, I cannot flash through fastboot and goo manager won't work. Guess this phone is not getting any custom roms.
your bootloader is unlocked though?
Yes, via htcdev (it also has the ***unlocked*** status in recovery).
Here's your full proof method.......
Boot up phone all the way, enable USB debugging
Download-
http://db.tt/sXmdepmX
Stick it on root of your internal sdcard.
Open up your command prompt and cd to your adb/fastboot directory.....type-
adb shell
su
dd if=/sdcard/twerp.img of=/dev/block/mmcblk0p22
Once it's done, do it again for good measure...
press up arrow, it rewrites last command, and press enter.
When done type
exit
exit
adb reboot recovery
There u go.......twrp recovery installed:beer:

I am on Windows 7 and have 2 USB 3.0 ports but currently not hooking up device to those ports.
With bootloader unlocked you should be able to flash a recovery. I see the error your getting when flashing twrp from bootloader and it looks like a communication error of some sort. It's not the phone blocking it......try all your USB ports when in bootloader, make sure your phone says fastboot USB also....if nothing else try a different pc, because it's not the phone, it's def. A pc issue I'd say

[Q] Stuck at X screen

Obviously I'm a noob, so sorry if this is stupid or there is an obvious answer (I've spent a lot of time looking and couldn't find it though). I was having problems with my phone so decided to flash back to stock and relock it to 'start again'.
Maybe that wasn't a great idea because I've had lots of problems since then. When I try to flash back to stock using nexus root toolkit I get "failed (remote: invalid bootloader)" and the phone finishes still in bootloader. There was a suggestion to force flash, but given the warnings around that I'm pretty nervous about doing that. If I then start my phone up it stays on the google screen for quite a while and then gets stuck on the X screen (it isn't frozen because the animation keeps running, but nothing else happens, even if I leave it for an hour).
I did a bit more reading and tried wiping the dalvik cache and cache. It then said it was upgrading android, optimising apps etc, but then got stuck again. I tried resetting again and the phone now restarts when I push the off button and slowly goes through both the google screen and X screen.
This might be a stupid problem, but I'm stuck so any help would be great.
Flash the stock images manually rather than with a toolkit. You can find a guide stickied under the nexus 5 general section.

[TUTORIAL] How to flash a factory image | Return to stock | Unroot your Nexus 5
Follow this carefully step by step using method 2. Be extremely careful flashing the boot loader, in fact you can probably skip that part. As long as your boot loader is always in tact it's virtually impossible to brick. As of right now you're stuck in what's called a boot loop. Most likely, either your boot.img (not the same as boot loader) or system.img (aka ROM/firmware) is messed up and is causing it.

Go into fastboot mode and run "fastboot devices". If the device shows up there, that's good enough.

Thanks, that worked. But having done it when I reboot the phone it does the same thing (hangs of the Google screen for a long time then moves to the X screen and stays there). My phone is rooted and I have clockworkmod installed, so I selected fix root when asked, not sure if that is relevant?

And you are following the factory image flashing guide that has been provided above?
Can you try going through the guide again, and tell us the specific errors that you are encountering.
And use method two, not the first one that talks about running the flash all script. You should be doing command's like "fastboot flash boot boot.img"

Don't worry, you'll get it, eventually. When you first start doing this kind of thing, it takes some getting used to because you have to read VERY carefully, and perform each step EXACTLY as stated. Computers are absolutely unforgiving of even the tiniest mistake, so you have to take your time, and be patient when you have to start all over. But, it's a challenge, and a learning process, and a lot of fun, once you get the hang of it.

OK, step by step. If you need more detail yell out.
1) I've downloaded ADB and Fastboot
2) If I put ADB devices into the command prompt I don't get any devices listed. But if I put in Fastboot devices I get the serial number of my phone
3) Previously I'd been using method one. So I now extract the image for hammerhead krt16m to my f:\ drive. I've also extracted radio-hammerhead-M8974A-1.0.25.0.17 and bootloader-hammerhead-HHZ11d to the same location and renamed them to radio.img and bootloader.img respectively
4) Phone is connected to computer and in fastboot (and detected by fastboot devices)
5) In command prompt when I type in fastboot flash bootloader f:/bootloader.img I get the error message FAILED (remoteL invalid bootloader image).
6) Flashed radio.img and rebooted bootloader and system.img (no reboot) without any errors (although they took a while)
7) Flashing userdata.img got the error 'FAILED (remote: flash write failure)
8) Performed all the remaining commands without any errors (when erasing the cache I got the message 'Did you mean to fastboot format this partition? erasing 'cache'... OKAY
9) Entered recovery mode. Earlier when I did this it was fine, but now (like when I try to start the phone) the screen lights up but no text etc appears
10) At this point I'm stuck, as I can't see the cwm text so can't select wipe data/factory data reset (although I did do this as part of earlier attempts)
From the 'on but no text' state, I can using the on button to restart into the same state or can enter fastboot (where text etc appears fine)
One at the boot loader you said you put f:/bootlaoder.img that was wrong, no drive letter. You do not need to flash your boot loader though anyways. Avoid doing that unless you have to, it is the only thing that will brick your phone.
You said system.img flashed fine, did not see any Menton of a boot.img or recovery.img. you need all three of these.
So, start over again. Make sure you flash a boot.img system.img and recovery.img separately. DO NOT flash the bootloader.img unless you have to (to update). Again, the boot loader is the one thing that will brick your phone if done wrong.

Sorry I just read through that tutorial and it does tell you to use drive letters. Im used to flashing with my files in the location of fastboot so I don't need to do that.

@op why you are flashing 4.4 images?? it has a different bootloader then 4.4.2.
i guess your primary bootloader now is 11k and not 11d or 11a .....(since you took the ota out of the box)
bootloader version must match with the rest of images.
so download 4.4.2 images and flash them using 11k bootloader. (note that you have the old and new bootloaders on your device, volume down + power will take to the new bootloader 11k, and Volume down + volume up + power will take you to the old bootloader).
regarding adb command, it will not work in fastboot mode, it works when booting in os with usb debugging enabled, or in custom recovery mode
Good catch.

Thanks I'll try that. Is there any way for me to confirm on my phone what my primary bootloader is?

Will try that, thanks.
I'm pretty sure I've done something stupid to cause this and I had a thought about what it might be - my phone was still at 4.3 for some reason. It would receive the update and install it, but the version wouldn't change to the new one. So should I try to track down the old 4.3.? bootloader?

4.3? The nexus 5 ships with kitkat 4.4 ...there is no 4.3 for it.

TF700 stuck in Boot loop ... have access to bootloader

Hi,
I've posted on this topic on transformerforums website but have not had any success (despite valiant attempts from the guys on the forums).
I am unable to post the link here, please PM me for a link to my original post.
Basically my TF700T got stuck in a bootloop. I have unlocked the bootloader but have not flashed it so it's on stock ROM. I have not been able to flash a recovery ROM and am at a dead end as to what to do.
I am able to get to bootloader and I when I run
Code:
fastboot devices
I get the following output
Code:
015d2a506733f618 fastboot
Which all seems correct. I have access to the tablet when connected to my pc.
When I try to flash the recovery rom, it takes a very short amount of time and on my tablet the device hangs (i.e the RCK icon is no longer flashing). I have checked the blob, it is the correct one and the MD5 hash is correct.
Code:
C:\androidsdk\platform-tools>fastboot -i 0x0B05 flash recovery twrp-2.7.1.1-tf700t.blob
sending 'recovery' (6894 KB)...
OKAY [ 0.868s]
writing 'recovery'...
OKAY [ 0.089s]
finished. total time: 0.958s
I can get back into the bootloader if I restart again but attempting to flash it results in a hang.
I have tried to insert an sd with the stock ROM and boot in RCK mode but this has not worked either.
Has anyone any suggestions as to what to do?
The tablet is 2 years old now so not under warranty.
thanks in advance.
anyone have any suggestions?
I'm going on holidays on Thursday and would really love to get this resolved before I go.
deleted
Shameless bump .... are my only options to return this to the manufacturer?
Anyone any suggestions, do you need more info from me?
What you did looks correct, only the short time for "writing" looks suspicious. Try the fastboot command again, but replace "recovery" with "staging", maybe that works better. At the next reboot you should see a blue progress bar on the boot screen for a few seconds and it should reboot again.
Hi,
Thanks for the reply.
I tried as you suggested and looks like the same results. I'm doing this in windows 7 and have opened the command prompt as Administrator.
Code:
C:\adb>fastboot -i 0x0B05 flash staging twrp-2.7.1.1-tf700t.blob
sending 'staging' (6894 KB)...
OKAY [ 0.869s]
writing 'staging'...
OKAY [ 0.084s]
finished. total time: 0.955s
Is there any way I get get logs from the tablet itself?
I had been thinking was this a permissions thing although I am able to run
Code:
fastboot boot
Code:
fastboot boot-bootloader
and they work correctly. So I do have access but for some reason the partition is not getting flashed correctly.
Does anyone know what the partitions are used for?
I assume the system partition is used for the actual system image but what is the staging partition used for?

When blobs are written to the staging partition, on next boot. the bootloader flashes the contents to the relevant partitions (i.e., kernel, system, bootloader)

Hi sbdags,
So it looks like I'm stuck at this point. The above command seems to work but the time for flashing the recovery blob to staging seems very short which probably indicates that this has not happened correctly. After the above command, on next boot when selecting RCK from the bootloader menu the tablet attempts to perform the update but then I get the android error screen (android dude on his back and error message).
Any suggestions as to what I can do next?
thanks
Paul

I don't think I can help you, but can you post the build number of your bootloader? I remember someone had a bootloader for the TF300 on his TF700 and was then unable to flash blobs.

Hi, I fairly sure I have the correct bootloader (WW_epad-10.6.1.14.10-20130801 A03).
Just to clarify, this is a stock rom I have on the tab. I have it unlocked but not rooted.
thanks

Your bootloader is ok.
Did you PM Josh? What did you guys try?
If he couldn't help you, I doubt I can...
Aside from the suggestions I gave you on the Transformer Forum, I'm stumped...
So again:
Do not use USB 3.0 ports
Uninstall the fastboot drivers and use the one from here: http://forum.xda-developers.com/showthread.php?t=2646279
Check the fastboot.exe version and see if you can find a later one.
That's all I can think of right now....

Yes I contacted Josh and shared my desktop with him one evening. We didn't resolve it. I've tried the flashing on 3 different computers.
One of them is an old laptop running ubuntu that I know only has USB2 ports on it.
The only thing I can think of is that I lost my original charger/cable but I spent the extra money to get an OEM one again so I hope that is not
the issue.
Could the cable be the issue??

If you got the charger from anywhere else but Asus - yes, that could be the issue. And the only one left I can think of....

When you are in fastboot type via CMD fastboot reboot OEM. You will get a black screen with a silver htc signaleert. Now you can install a recovery via fastboot.

And this is a absolutly wrong advice.!!!
You have to flash the recovery in fastboot mode not in RUU mode. (As you can see in the "signature FAILED" output.)
First Question is... are you s-off?
If you are s-on..
What you can try is in normal fastboot mode:
"fastboot erease cache"
then
fastboot flash recovery recovery-name.img
greets
As you can see he already Flash this trough normal fastboot and thats not working......As seen in his remark about failure.

OK once more.
He cannnot flash recovery in RUU mode..or what du you think does FAILED (remote: 12 signature verify fail) mean?
Only firmware and HTC signatured content can beflashed in this mode.
and these things only if he is s-off or his cid is matching.(RUU´s)
If you advise him to flash a custom recovery in this mode he will never ever get this to work.
So this advise is wrong...
Ok, you're right. But i f you know how to help this guy why don 't you?
Sent from my HTC One mini using XDA Free mobile app
So what do you think I want to do?
I asked if he is s-off ?
Then I posted a (possible) solution and try to stop your nonsense.
But without his answer there is nothing more to help at this time
So please stop this kind of posting and stay OT otherwise I report you.
This is not the way of XDA-rules if you dont know what to post...don´t post.
peace
