[q] unable to boot - Acer Iconia Tab A100

Hello friends...
yesterday my acer a100 goes stuck at boot screen (acre logo) after hang and restart
my tablet is ICS rooted and having swap between sd card and internal memory.
now when i tried to boot into recovery mode the tablet shows different error like:
-failed to mount /cache
-cannot open /dev/block/mmcblk0p5 ....
after that when i press home key it shows menu of recovery mode
-reboot system now
-apply update from external storage
-wipe data/factory rest

That's usually then first sign of the bricking issue, I'd send it in asap for repair if under warranty.

CWM 5.0.2.7 ignoring ext partition?
Hi everybody. I have installed CWM v5.0.2.7 on my SONIC U8650 smartphone. I'm having a slight problem with this recovery (same occurred with previous version 4.0.1.4). It's not saving the ext partition that I have on the sd card. When I perform a backup through CWM, it skips the saving of sdext as this partition is not being found. Also, with previous CWM version 4.0.1.4, there was an option to manually mount the partition (just in case it is not found at the time of backup) in the "Mounts and storage" option. This option is no longer present in CWM 5.0.2.7 so I can't manually mount the partition (whether this would let CWM recognize the partition and make a proper backup of it). In the end I'm not able to have sdext fully backed up (I resorted at doing a manual backup on my notebook with LINUX with partimage) along with all the other partitions such as /system, /data, /cache etc etc. I therefore wonder if this is a bug and if there's a way to get around this.
I have another smartphone with CWM v5.0.2.3 installed and on this one the backup of the sd-ext partition does work (and it is ext4, not ext3). I wonder if on this 5.0.2.7 version for SONIC, ext3 partitions would be recognized or not.
P.S.: The CWM 5.0.2.7 I installed was taken from here. And this is the installation guide. Is this the same CWM as the one posted here?
EDIT: I have flashed even this version posted here and still the same problem.... it desn't backup my sd-ext partition. It does backup boot_image, recovery_image, system, data, android_secure, cache but not sd-ext (no sd-ext found).

Hi dude:
If you wanna sd-ext on your sd card you must follow (exactly) this easy steps.
1- Full format in FAT32 your SD card with Mini Partition 7 (windows) or gparted (linux); per example: Primary FAT32
2- put your sd card into your phone and get into recovery menu.
---go to "mounts and storage" and format this parts:
---/boot
---/cache
---/data
---/sdcard
---/system
3- Go to the beggining of recovery menu and select:
..."wipe data/factory reset"...(say YES)
..."wipe cache partition"...(say YES)
Go to ...advanced ..."wipe Dalvik Cache"...(say YES)
...go back...
5- Go to...advanced...partition SD card (say 512Mb to ext and64Mb to swap)
...go back...
...go to...mounts & storage... mount USB storage...
... conect the phone via USB and pass your favourite ROM to the cellular
6- select "unmount"
7- Go to "Go Back"
8- Select "install zip from sdcard"... "chose zip from sdcard" and select your ROM
10- Say YES and wait untill your ROm is installed
Congratz, now you have your U8650 with custom ROM and ext partition with swap
P.S. I know the steps are some tedious think but, it works at 110% man

Please help! Huawei u8652 (At&t Fusion)
Am stuck here with an At&t fusion which a friend purchased a not long ago. He set it up with a lock pattern but unfortunately his colleague took it up and tried more than 5times. Now the phone is asking for the gmail account used to set it up. Which he did not change when he got it. I would like you to give a step by step guide to get the cwm on it in other to flash it with custom rom. The menu can't be accessed so I thought your method would be the best.

Sorry for the late reply and many thanks for the tip. I have been using the SONIC so far without the need to restore the system which works fine, so it was not urgent and therefore I kept it as it was, never tried again to overcome the problem. Only a question: does this procedure (different from the one I used) let the system correctly generate the backup of /sdext partition in CWM? Because I don't see why it would work with this procedure and not with my current sdext partition, which I created using gparted on a linux notebook.
Easy as pie, thank you.

I've been having similar problems with creating/saving the partitions. I used a procedure like yours and managed to get the partitions created.
But your write hits it on the head......thanks.

1. Which CWM version are you using
2. What ROM are you trying to flash
The first thing you should realize, is that formatting the /system means that Android no longer exist in your phone. Therefore you can no longer boot into your phone; boot into Recovery instead.
The second thing: Are you sure you're trying to flash a ROM explicitly made for the W? ROM from different devices most likely will not be able to run on the W. In fact, the error message "No space on this device" might very well mean that CWM tried to flash the ROM onto the wrong partition.

[Q] Samsung GT-I8262 core upgrade to kitcat

Hello,
I have a Samsung Core GT-I8262 running on android 4.1.2.
This device is already rooted and checked with "Rootchecker", this give the message that the device is succesful rooted!
When I go in to recovery mode I get another screen then the explenation on your site;
-reboot system now
-apply update from ADB
-apply update from SDCARD
-wipe data/factory reset
-wipe cache partition
-apply update from cache
When I choose " apply update from SD Card" my phone can't find it.
Can someone give me an explenation how i can resolve this issue.
Kind regards.

Is this phone salvageable?

Pressing Vol Up, Home and Power keys give me the following (I have an screenshot but I am blocked from showing the screenshot):
Android system recovery <3e>
K0T49H.N7105XXUFNE7
Volume up/down to move highlight; power button to select.
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
It reports many missing file systems before that
I tried to flash the stock ROM using Odin. Vol Down, Home and Power keys give the Download screen, but nothing gets downloaded. Tried it from three different PCs.
Is my phone recoverable? What is "apply update from external storage" or "apply update from ADB"? I haven't tried wipe data/factory reset yet because I hope to salvage the WhatsApp backup file if it's still there.
Thanks.
Try flashing custom recovery if possible.
Of you succeed then using aroma file explorer to copy your WhatsApp backup to external SD card....
After that you can wipe everything and start installing a rom from scratch.

Corrupted internal SD card / can't access OS (CM 12)

So I installed an update to CM 12 and rebooted without wiping any cache(s) etc. The phone was stuck in the CM boot animation loop for hours - this has happened before and I was able to rectify the problem with the below process - so I decided to boot into CWM recovery and clear Dalvik cache and perform a cache partition wipe. Before, this has sorted the initial problem but this time I was again stuck at the CM boot animation after rebooting.
I booted into recovery again and tried to access my interal storage to locate a CM zip but couldn't access the partition. I kept getting an "E: Can't mount SD card" error when I tried anything that involved accessing the internal SD card/
I rebooted and entered recovery again and decided to perform a "wipe data/factory reset" after deciding that I wanted to go back to stock Android. However, the internal storage wouldn't format because it wasn't mountable.
Now when i reboot I'm stuck on the white HTC screen with "this build is for development purposes only..." at the bottom - I can't even get into fastboot!
I really want to restore and flash stock Android. How can I format the internal SD card and flash stock ROM?
