[Q] Desire HD - no reaction in the boot menu

Hello. Today, in normal use the phone suddenly hangs.I ran it again in the bottom left corner of the screen appeared the words EMERGENCY MODE.I decided to switch off the phone again, however, joined the boot menu where nothing can be done(i can not move or nothing to choose).After removing the battery and re-insert the phone once in a few seconds goes to the Boot menu, and repeats the situation, do not respond.The only thing that happens after a while subtitles that pop up .. pd98diag.zip file and others are wrong or missing.However, after about 1-2 seconds it disappears and the phone still does not respond to anything.
The phone was recently rooted. Custom rom was uploaded: Arky's ROM 2.3 OC-TV.
Sory for my bad English. Any ideas ?

[Q] A100 bricked?

I am a newbie in this forum and would need some help to unbrick my tablet.
I have been using leaked ICS in the past 2 weeks or so. This morning when I started using the tablet, it was running VERY slowly. I rebooted it but it was stuck at Android screen for more than 30 mins. Running out of patient, I restarted it 1 more time and it can now only get to the Acer screen no matter how long i waited.
Tried a few things already with no success:
1. Hard reset using the pin hole bottom left - nothing changes
2. Go to recovery mode trying to use the HC rom (rename to update.zip) using volume up button. Once the green droid shows up for a few seconds, it turns into a droid lying down with a red exclamation mark. It will then restart itself after 30 seconds or so.
What's going on with my tablet? Any help would be appreciated.

Any help??

Cant use HC ROM...
As long as you are not BOOTLOADER UNLOCKED you can use a regular UPDATE.ZIP for your device... You cannot "DOWNGRADE" that is, you cannot go from ICS to HC again without some form of "hack" or "workaround"
See if your tablet allows you to re-flash the ICS build you were able to update to and post back... It may just be it corrupted some files...
Let us know... jejeje
UPDATE 1: And... Dont use VOL+, its supposed to be VOL-.

I tried the vol - button (the one farther away from the orientation lock button), it seems like the tablet was not doing anything different at all. It will eventually get stuck at the Acer screen.
If i use the vol + button (the one closer to orientation lock button), it shows the text "Booting recovery kernel menu" in Acer splash screen. It will then go to green Droid screen with a spinning sphere. In less than 5 seconds, it seems to fail to boot into recovery menu with a 'dead' droid with a big red exclamation mark.
These are the update.zip file I found in the forum. They all gave me the same error:
Acer_AV041_A100_1.012.00_WW_GEN1.zip
Acer_AV041_A100_1.014.00_WW_GEN1.zip
Acer_A100_1.014.08_COM_GEN1.zip
Any more help? I can get upload a video to Youtube if it helps.

HOME Button?? Maybe??
When you get to the GREEN ANDROID... click on your HOME button and see if you get a bootloader/recovery type menu at the top left... If you dont get it from the GREEN ANDROID, try thesame (HOME button) while the RED DEAD ANDROID is showing...
When mine did that for a bit, I found there was a "hidden" recovery built in... Again, try to go to recovery and press the HOME button... You may have to press it for a few seconds...

Thanks for the pointer! It now shows a lot more information (while the sad Android with red exclamation mark is in the background)
I can scroll down/up using volume button for these options:
reboot system now
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
At the bottom of the screen, it is showing a whole bunch of yellow text:
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
(repeat the above message for /cache/recovery/log, /cache/recovery/last_log, /cache/recovery/last_install
How can i select an option from this menu, btw?
I also tried to use the vol - button. I found that if i keep flipping orientation lock back and forth, it will show 2 messages at the top left corner showing "Erasing Userdata...Erasing cache..." in the Acer splash screen. Then it will freeze again....

PWR button to select
Make selection with Vol+/- and press PWR button to select... See if you can do a factory reset...
"
Or put the UPDATE.ZIP into your microSD and see if it lets you select the "Update from ZIP" message

Pressing the power button doesn't do anything. If i press it long enough, it just shuts down the tablet.

I dont know man... I cant get mine to there because I have the unlocked bootloader now... Have you tried either of the volume buttons... maybe the HOME KEY? that may be it...

I tried every single buttons on the device w/ no success. The home button only hide/unhide all the text. Vol +/- can scroll up/down in the menu. Pressing the power button doesn't work at all.
In the system recovery screen, it has the yellow text complaining about /dev/block/mmcblk0p5. Is there anything i can do with this?
It looks like I am running out of ideas to revive my lovely tablet. Is it time to throw it to a trash can?

Some people are trying to do it through APX mode but it can be difficult if you don't have certain info specific 2 your tablet...

Do you have pointer on what i can try? Since it's already bricked, there is nothing to lose to try it out.

no response? I guess this is a dead topic

same problem!
my A100 does not work and face the same problem now...
I could not select the item to even recovery or anything.....
Any one can help?

I called acer. We went through the hard reset thing. When he found out that it didnt work he told me to send it to them. So im packing it up tomorrow. Not sure if they are gonna try and fix it or just send me another one. We will see. Will keep u posted

I have been having the same problem. I can get into the system recovery menu from the dead android, but I don't know how to select menu items.
I've tried all the buttons on the device, but none work.

EXACTLY the same symptoms and exactly the same issue with not being able to select anything off the recovery menu.
Ugh.
Unfortunately mine is rooted so I assume if I send it in to Acer I will have to pay for the repair myself.

I had the same problem on my son's pad, tried every type of reset w/o any luck I finally got tired and called Best Buy they told me to bring it in and they tried the same resets before giving up and shipping it to Acer for repair. I just told them the screen froze after ICS update and 4 days later my son has his pad back in working order.

[Q] Desire Z vanilla bricked?

Hello XDA,
I've searched the forum and couldn't find anything similar to the problem I have though, so here it goes...
This morning I wanted to check my Facebook through the official FB app on my phone. The whole thing hung up - couldn't even turn the screen off with the lock button. I removed the battery, the phone began to restart, then it restarted the process, then again, and again...
I removed the battery, the SD card and the SIM card, no difference. I inserted both cards and since then the phone just goes to the white screen with the "HTC" logo (not the one with the 'quietly brilliant" - the one before that) and then nothing happens.
I googled here and there, eventually got to the recovery screen. After choosing the 'recovery' option the screen goes black, then a green icon appears, after that a red triangle with an exclamation mark appears and the whole process restarts. After about three-four restarts the phone goes to the white screen with the "HTC" logo mentioned above. If I press Vol-Up+Power when the red triangle appears I get these three lines:
Code:
E: can't open /cache/recovery/command
E: can't mount /data/data/recovery/log
E: can't open /data/data/recovery/log
FAKE EDIT: when doing the restart to check the three lines while writing this post, after the third reboot to that red triangle icon the phone loaded the recovery menu with the options to reset to factory defaults, etc. I chose to whipe cache and after rebooting got as far as this "quietly brilliant" screen. After that the screen died, power button not responding. Another battery replacement and the difference is that now, after the screen dies the phone just restarts the "quietly brilliant" screen (and the annoying sound...).
Now, here's the trick that makes my case unique, compared to other people's problems on this forum: I did NOTHING to the phone earlier. It's the official, out of the box Android, updated to the latest version given by HTC (2.3.3 I believe) using the update option within the system, I didn't ever try to root it, mount anything, change ROMs, shorten the loading time. The only thing I did was installing some apps from the Android Market and the K9 mail client from an install file downloaded from their official site.
Can you help, XDA? : (
Cheers!

Could be a bad emmc or curropt partition, either wont matter if rooted or not. Try booting into safe mode (hold down s while powering on) if it boots you have a bad app, if not then one of the above is your problem.
If it doesnt work try a factory reset, if that still wont work then download the latgest ruu directly from htc, if that works your fine and it was just a curropt partition, if not that you most certainly have a bad emmc which unfortuntetly is not so easy to replace.
By not rooting it would be hard to check which chip you have other than opening up the phone and looking, which would void warranty if there even is any left. I find that in most cases rooting an android phone makes issues that arise easier to deal with in the long run but when its harware at fault it never matters

Thanks for responding!
I'm afraid I'm a noob in regard to smartphones, so I'll be needing a bit more detailed advice...
So, first of all: what do you mean by "hold down s while powering on"? What's "s"? : ) The "s" key on the QWERTY keyboard? If so, it doesn't work, I get the same greet screen restart loop as earlier.
Second: where do I even start looking for this "ruu"? A simple Google search didn't help me much. I got to a different forum with someone's post containing a dead link... : /

Yes that holding the s key, which being it didn't work it wasn't a malicious app causing your problem. For the ruu go to HTC.com > support > pick phone > go to downloads > find latest firmware/software download
You will need to get fast boot working to do this and I believe there will also be a link for any drivers you may news

Possible hardware failure? Unable to boot - claims no OS and won't mount data etc

I think my phone may have had a catastrophic hardware failure but I am hoping not and maybe some of you clever people can help me resurrect it.
I have been running KK ParanoidAndroid without any problems for a few months. Yesterday I tried to boot it up and after showing the Google screen the screen went black then a single horizontal white line appeared 3/4 way down the screen. It stalled there forever so I pulled the battery and booted into TWRP recovery. It seemed to take a lot longer than normal but did boot into TWRP OK.
Once there however TWRP reported no backups, no OS and no storage space (0 MB). I couldn't mount any partitions,. I tried factory reset but it appeared to fail and just made the phone vibrate for a while. The log shows:
Unable to mount - /system, /cache, /data etc and something about no valid partition for MTP
Then the screen greyed out, faded to black and the phone powered off. Now it seems pretty much non responsive.
Any thoughts, other than bin it and get a new phone?
EDIT: It seems it hadn't powered off, just gone blank whilst attempting to wipe. I am now back in TWRP but the factory reset has failed. So. It seems I still have a functional recovery but not much else. Any help much appreciated.

In the absence of any responses I've searched a bit more and decided in the end to try to install a factory image using fastboot. I was holding out to see if there was any way I could save any user data but in the end that seems unlikely anyway.
So, I followed this guide: http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/
It all seemed to go smoothly until the final commend - after flashing the zip containing the system, boot and recovery images I got the error message "FAILED (remote: Write Fail)"
Hmmm...
Regardless I tried to finish off with fastboot reboot. As I hit enter the device screen faded slowly to a kind of washed out grey and the horizontal white line appeared on the display again (as before - see my first post). No further progress, and the device became unresponsive. I pulled the battery and tried to boot, and it bootlooped once to the Google screen before the screen faded to a washed out grey again and it became once more unresponsive.
After pulling the battery once more I can still get to fastboot, and I can now get to stock recovery, but otherwise I can't seem to get any further.
Is it toast??

[HTC ONE M8] No OS Installed! Problem after forced reboot

Phone Details:
HTC ONE M8x
Stock Rom (Rooted)
Kit Kat (can't remember the exact version)
Unlocked BootLoader
S-ON
Ok so I'm having a bit of trouble with my phone which all started after a sudden reboot.
Heres the full story so the pros might be able to understand what happened:
While I was browsing the internet, my phone started lagging really badly. After a few more seconds of lag, the screen suddenly froze. When I tried to reboot the phone, the screen just offed and wouldn't turn on anymore though I could still feel the haptic feedback from touching the screen. Holding the power button still brought up the power menu so I decided to reboot and hope for the best. After the reboot the phone was still laggy but not as bad as before however a new problem appeared. I noticed that opening the File Manager App took longer than average and that moving/copying files from internal to external storage would freeze the app for a while but still finish the command.
After getting irritated of the sudden hiccups I decided to boot into the Recovery Menu (mine is TWRP) and try something to see if it works.
I cleared 'Dalvik Cache' and 'Cache' first then rebooted. The phone started like normal but when it got the part of Updating Apps, it stopped at Starting Apps. So I decided to reboot into Recovery again, after clearing the Dalvik Cache and Cache again I went to 'Reboot', but... (HERE'S WHERE THE BIG PROBLEM HAPPENED) instead of choosing 'Power Off', I clicked 'System' and the phone froze. After a while, the phone rebooted but this time it didn't want go past the point where it shows the ONE logo. Panicking, I went to the recovery mode again and went straight to 'Reboot', when I clicked 'Power Off', the notice at the top said:
No OS Installed!
Which led me to believe the phone wouldn't boot because of the lack of an OS... (OBVIOUSLY):crying:
Questions:
1) Is this problem considered as Soft-Brick or Hard-Brick?
2) How can I fix my phone?!
3) Can I install a stock ROM to fix it?
