[Q] Unstable state - Acer Iconia A500

Hello,
my A500 is now in unstable, weird state, i tried to flash ROM update, but i forgot an old update.zip on SD and also that i have no CWM more. My fault of course.
It started to flash again, suddenly stopped. Now if i reboot, i am on my old ROM, but only Power off .. shutting down message appears. I can touch time, settings, but unable anything to do. Message is still there. I tried to press RESET button, no way. I tried to flash it again with rescue Update.zip no way. Just message still there.
Looks like, it wants to shut down, but this never happens from some reason. But why it is again after reboot there, i don't know.
Any advice please ?
Thanks, Ed

Can you install Acer Recovery Installer so you can install CWM from within Acer Recovery Installer?

Try flashing cwm mod using Acer recovery and quickboot to reboot into recovery. If that fails install itsmagic via fastboot or cwm mod 1.3.4 via manual method posted. Don't despair mate you be fine.

I had exactly this problem myself a few days ago...cwm was corrupted and the fix was to download official rom which was chinese and put it onto my external sd card. Then pressing power/volume up forced the update which also reset the cwm and boot sector back to stock. After this I used the official 3.1 rom on this website to update with english version and market app then finally install cwm to use roms.whew it was painful and i cannotremember where i got the chinese rom from...so im only slightly helpful.

There are many stock ROM links on this forum, I don't think he'll have a tough time finding one.
Thanks for sharing your fix for what appears to be the same situation.

Update
I am not able to put there any ROM, my last hope is that chinese, do you have some link on Multiupload (other site are blocked here).
Funny is, that i see lock screen, proper internet connection, mail marks, proper time and Charging still on 15% forever

Update 2
Looks like that battery is wrong, goes to service, thanks all for help and comments

Wait a second...
Had the exact same problem with failed ota update this morning - managed to resolve it...

thats just the default android boot screen, looks like the theme messed up your framework... hold on i'll make a .zip you can flash from recovery to fix it
Thanks, but how do I get the zip on the phone? It does not react to anything anymore. I attahced it to my PC but nothing....

im just downloading the rom for you now so i can extract the framework, if you pull your battery out, you can either plug in your charger while its off, this will bring up recovery, or while its off, hold vol down and press power, that will take you to bootloader, and just pick recovery from the list, now when in recovery, if you navigate to the mounts and storage menu, choose the option mount usb storage, you can now connect to a pc as a disk drive and copy stuff to your sd card
im having trouble uploading attachments to xda at the min dya want me to upload it to megaupload for you?
AndroHero,
Thank you for helping me out. I didn't know about the vol down press power option which allows you to acces the sd card and intall a new rom. I had the revolution rom 2.0.9 already. It's installing as we speak. Much thanks for the tips!
To early hooray. I choose the option with the revolution zip for a complete install. After the install I selected rebouut system now. Now it stays on the white HTC screen with the text HTC quitely brilliant. Flashing every 3 seconds or so....
What to do now?
Everything is resolved. revolution is up and running again. I had to un the fullwipe.zip and that did it!
THANKS a lot for all the tips....again

Did you do a full wipe before re-flashing your ROM? even if you did just repeat the process , full wipe /cache, /dalvik-cache, /system and then re-flash the rom fingers crossed it should work
Hi,
I am having a similar problem. I tried flashing the cyanogen mod and after installing it the phone doesnt boot up. Its stuck on the t-mobile boot up logo. Ive tried restoring my back up but I get the same problem.
Any help would be great!

Could it be possible that you installed cwm 3005 and tried a restore with that. I had the same problem. Went back to cwm 2.5.x and then restore worked.
Sent from my Desire HD
I think there will be a lot of scare because of this CWM 3x...
Same happened to me the other day, stupidly accecpted the update prompt from Rom Manager, did my backup and went to install Cyanogen 6... Got stuck at HTC logo next boot.
Thankfuly, had Leedroid 2.0 on the SD, too, and that one flashed properly
Thing is that when I try to downgrade the Recovery to 2.5x I get an error and really can't be bothered with ADB pushing stuff around, so using Cyanogen 7 for the time beeing
Anyhow, CWM 3.x is likely your problem, easy to fix ^^
Wanting to change my theme on the Samsung spica I had theexact problem on cyanogen mod. Had to redo the whole rooting and installing the Rom again to get to work.
Sent from my Desire HD using XDA App
yes, is some script...back to recovery 2.x

I can't update to ANY rom...

I wanted to update to CM7, once it rebooted into recovery mode it gives me an error. I got the official Sprint update and the same thing happens. Once it verifies the file, something happened and it says there was an error and does not update. I did a factory reset on the phone, got the official sprint update and the same thing happened. The error is always "signature verification failed" on both roms.
What can I do?
Thanks.
When flashing a rom, are you selecting 'install from SD" then find where you saved the zip, etc?
It sounds like you're trying it thru the update.zip option (don't do that). Also, when you reboot into recovery, you should be seeing orange type clockwork 3.0.0.6 (not blue or green).
Ask if you have any other questions.

Are you using cwm 3?
Thanks for the replies guys.
I am using clockword mod 3, with their option on updates.
I don't know how to do the "update from sd", haven't seen that. I'm not sure if I am seeing the orange you mention...I just go to restart in recovery mod from CM3.

If you don't see orange text you're not on CWM3, you are either on CWM 2.5 or stock recovery and neither of those would be used for what you want to do.
Ya, check out the development section on getting the latest clockwork, if you don't have it already. And just in case, first, try powering off your phone, then hold camera button, volume down and power (after device is completely shut off). If you don't see orange text, you should update to the latest clockwork.

I turned off the phone, turned it on with the vol down/camera button and it automatically booted on CM recovery 3.0.0.5. Doing a rom backup. Then I see the orange text with several options but I can't pick any of them...I'm hitting the "home" button but nothing.
The phonr wont respond...I can toggle between the options but thats it.

And now the phone is stuck in the SAMSUNG screen...
Bricked...tried factory reset and nothing. Tried restore through CWM and nothing...
If you are able to get into CWM or download mode then your phone is not bricked. It sounds like you will have to use ODIN to restore your phone back to stock.

ClockworkMod 3 automatically converts your phone's filesystem from RFS to EXT4. You need a ROM that supports EXT4 or else it won't boot.
You wanted CM7 so go ahead and flash that if it's on the sd card. If you don't have it on the card it's easy to fix. Just turn off your phone and plug your memory card into a computer and copy a ROM that supports CWM3.
Once you flash a ROM your phone should boot normally.
Bro, when u boot into clockwork (orange) are u opening the slider and using the arrows and enter key. ? You shouldn't be using the home key.
Don't be so quick to "I'm bricked" .. cuz that's rarely the case. And annoying when ppl are trying to help.
Sent from my SPH-D700 using Tapatalk
K, thx for being patient. I did Odin and its again working.
Now the phone updated to 2.2.1
For future reference, can this Odin method be used o update to a non official rom (like CM7)?
Thanks for all the help.
I wouldn't rely odin for that, and as far as I know, no. For frame of reference, I've probably flashed epic roms over 100 times, and have only odin'd 5-- Used mostly to return to stock/update a modem. So, odining probably wasn't necessary for you. Do what arashed says a few posts up.
I'm using SRF 1.1.0/Twilight Zone and its amazing. Battery lasts a lot longer too.
Thanks again.

[Q] EVO Rom/Root problems

I am having some serious issues with my evo. I have tried 10 different methods, googled 100 different help guides and still no fix.
I had originally rooted my phone using simple root and put the "fixed" froyo rom on there. Everything worked fine, but I was outdated and having some really slow issues so I wanted to try a new rom...Fresh.
Well I tried a few methods, but I somehow reverted my evo back to a nonroot of the original OS. Whenever i go into hboot, my recovery does not work. I push the PC36img and load it, then restart then I attempt to go to my recovery where it gives me the error picture with the yellow/red triangle. I then select recovery (after pressing UP volume and powerbutton) and try to load update from sd card. Everytime I do that I get a Failed error.
I've tried to reroot using several methods off this website, I've done everything I can to get it working but can't. Any help would be GREATLY appreciated!
Try reflashing your recovery image.
BTW I have hboot 79.0 with S-ON, so it looks like I def became unrooted.

Not sure how it would have just unrooted itself. I would run an RUU from here: http://forum.xda-developers.com/showthread.php?t=884060
Then, I would re-root and start clean again.

I would have waited about ten minutes then restarted the phone. If the phone is stuck at the HTC logo, then I would go ahead and re-run the RUU.

ok, finally got it working. Had to restart the phone manually and try it on a different computer. It updated it to the newer version of android and hboot, thank goodness! That was the easiest and most productive thing I've been able to do so far, thanks!
Well now I try to boot into recovery and get the same error:
can't open /cache/recovery/command
Then I get :
E: signature verification failed
Installation aborted
When i try to load update from sdcard

Ok, so, I think you said you got the RUU working which would have completely restored the phone to unrooted and stock from factory.
Now, you need to re-root your phone using one of the methods on xda. I used the manual method here: http://forum.xda-developers.com/showthread.php?t=829045. However, many people have had success with the one-click methods.
After you re-root (which will likely included installing a recovery), select a rom you want to try, boot to recovery, wipe and flash it. A great starter ROM is MikFroyo 4.6 or 4.5.
Try downloading the PC36IMG.zip from here: http://forum.xda-developers.com/showthread.php?t=705026
put that on the root of your SD card, then boot into HBOOT and it should find that PC36IMG.zip after a few seconds and ask if you want to flash it. Choose yes and let it finish. Should then be able to reboot into recovery.
ok thanks, i'll try it when I get back home

Ok, I tried this method...the filesize of pc36img.zip is only 3.5mb, but it didn't seem to work. It scanned the file then just went back to the hboot screen with my options never asking to flash.
I'm going to try to reroot using the other method now...
So I clicked the link and he forwarded to the autoroot.bat page so I used his method. It worked well (the 2nd time around) all the way until it started to push amon_ra_1.8-mod.... then after that it says rebooting into the bootloader, and it reboots into it and just says waiting for phone...
It does appear that my phone is rooted now, but my recovery is still not working. If I use ROM manager will it work since my phone is rooted or do I need to have a rooted ROM to run it off of?

Does your phone show s-off while in the bootloader? If so you should be able to run the FlashZip script and use that to flash the pc36img-sprintlovers zip. That one contains everything needed to bring your phone up to date and will leave you with a rooted rom and recovery.

FINALLY! Thanks a million! My recovery is now working and it installed the built in sprinter lovers rom, I guess the anti-virus was stopping it so I disabled it and ran the flash script. I was able to install Fresh on there, just to try it out. I do have a few questions though:
1. I noticed after going through many pages that to update to a newer ROM version you don't always have to wipe clean, you can just install (or flash) the new update? I noticed in Fresh there is a built in app that does that. Is this true for most ROMS or only certain ones?
2. I assume I am using the RA recovery. I noticed the backup/restore feature on there. What exactly does that backup and when should I use it?
3. I've noticed I've been very low with memory on my phone (not SD card), I have about 258MB free. How can I clear space and when I mount my phone what files are important to keep and can I get rid of, is it okay to get rid of my rom.zip's and radio.zip's?
Thanks again to everyone, autoroot was def the most painless root ever.

1) You'll want to always wipe your cache/dalvik (I do everytime I'm in the recovery) but the Data depends on the ROM. Usually if you are going from one sense rom to another you are ok and the same for AOSP to AOSP. Going from Sense to AOSP you'll need to wipe data though.
2) Autoroot comes with a modified version of AmonRA, they are mostly just speed tweaks. To make a complete backup of your ROM select Boot (kernel), System (ROM), Data (Apps & Settings) and .android (apps on SD card)
3) You can delete the zips from your sd card if you don't need them but that's about normal for free memory.

Phone Bricked? Please help

So I rooted my RAZR M using motofail2go, and all was well.
Installed 'RAZR-M-Safestrap-3.12', as I was going to flash a custom ROM. I first backed up my Original Rom using the backup function.
I then wiped 'System', and went to flash the new ROM, but the flash did not work, so I restarted.
Now the problem is when the phone reboots, it showes the Safestrap splash screen with the Recovery option and start normal, but it is not working, as not sensing my inputs or something, after about 5 sec it goes to a blank screen and sits.
I tried to hard boot into the Android System Recovery, and tried to download an official Verizon ROM and install using 'apply update from external storage' using my micro sd, but I keep getting an error E:signature verification failed.
Does anyone know where I can find an official ROM to set it back to normal so I can use my phone again?
Thanks in advance.
Also: My phone originally had 4.0.4 version.

if you can get back into recovery, you should be able to press "restore" assuming you backed up your previous ROM.

What you might want to to is use RSDlite and flash that image you downloaded. This seems like it would help you, though I have not personally tried it:
http://www.andromods.com/tips-trick...oid-razr-m-xt907-stock-original-firmware.html
EDIT: And once the flash is complete, I would reboot into recovery again and wipe data and cache and then let it boot into the phone.
EDIT 2: Oh, and in addition to RSDLite, you will need the Motorola USB drivers so your computer can see the phone over USB.

Constantly rebooting...

Hello, this is my first post here and I have searched for a similar post or issue but have been unsuccessful finding anything.
Please forgive me if I have posted in the wrong area, missed a solution somewhere and/or have not explained anything correctly/clearly.
My Nexus 7 (2012) (I installed Cyanogen on it (and updated it once) through their installer and it has run perfectly for months) started rebooting randomly one morning. I turn it on and it seems to be normal, then it will suddenly reboot. The time between reboots varies ranging from 30 seconds to a few minutes. I can not install or update any apps and any settings changed are reset back to what they were previously upon reboot. I have tried a factory reset and while it appears to wipe everything (all caches and data) when I reboot it is the same as before the reset (I also receive this message (after all other processes are complete) during the data wipe "E: unknown volume "/sdcard/.android_secure" "). I am able to turn on developer options but then the random reboot occurs and it is turned off. I have plugged it to my computer and see it listed, but can not access anything on it.
My intention is to wipe it using my computer (fastboot?) but I am at a standstill due to the rebooting and being unable to turn on developer options.
Any ideas or suggestions would be greatly appreciated.
Have you tried flashing another ROM in recovery? Perhaps try to see if you can access the filesystem while in recovery or if the bootloader brings anything up on your computer.

Thanks for the reply. Sorry for my delay in replying. I've been rather frustrated with this.
I flashed the official image (downloaded from the google site) using fastboot and it seemed to work as all messages said complete but when I rebooted, it was back to it's current state. I am at a loss. I also tried adb sideloading but that just hangs when it gets to installing. It does not reboot randomly when it is in recovery.

No worries!
So CyanogenMod is still installed? Oh my. Has anything at all changed? If you still have custom recovery installed, why not try a near stock ROM?

Yes. No matter what I do, when I reboot it's still Cyanogen. Being a semi-novice at this, I didn't backup the stock ROM I had before installing Cyanogen. It feels like a virus, but I pretty much installed the exact same apps on both my phone and tablet and the phone has been fine.
I used this image(nakasi kot49h). Should I try a earlier version?
Thank you.

You can always try. Also make sure you check md5 before flashing, that may explain why stock didn't flash correctly.
And I still can't get anything to work. Most recently I tried using wugfresh and EVERYTHING works except when it writes bootloader.img at the start. I feel like I am close but then it reboots back to cyanogen. lol
