Sounds good. However, let me be a little more specific.

The problem with all the previous recoveries happened when you tried to wipe /Data. All the other functions seemed to work well. Seemed to.

1. Recovery backup took longer than usual, especially on a bare stock install.

2. The first time you restore a recovery image, it would take "forever". Usually, it would complete the first time, but Data apps didn't function once the Rom booted. Nor could you download ANY apps. Any additional attempts to do a restore would hang at "formatting data". Once that happened, you basically could not install anything nor restore from a recovery. /Data corrupted.

So the question again, have you tested the /data wipes and formats via CWM? Several times after downloading apps, backups, restores?

Please don't take this the wrong way. We appreciate taking the time developing a workable recovery for the 70x. But the previous attempts caused needless bricked tabs. 1 dev, didn't even own a 70x to test it on and he pushed it out. And the other guy, well, whereabouts unknown, and knowing the previous issues, he also never bothered to check all functions before releasing his version. Claimed "I don't have a need to wipe data". :rolleyes:

So please clear this issue, before we get into the flashing portion. You have to understand, some of us, are a little "gun-shy" right now.

Thanks for taking the time to develop a recovery! I hope it works well!

[Acer Iconia A700 and A510] Moscow Desire:
I'll take a guess, that if the /data issue is working in the new recovery, and you can get it installed, you may be able to wipe the corrupted /data, and restore your previous recovery backup. If you used a CWM based recovery.

Also, I think I may still have my stock recovery CWM backup from my 701 on my PC (build .015) (I think). But considering it was done with CWM, you may be able to restore it. Might work, might not.

[Acer Iconia A700 and A510] paugustin:
OK I spent some time this morning with pawitp. He was able to make my A700 boot but the /data partition is reduced to 126Meg and if I try to format any partition it will break things again.

So it's a start...

Regarding restore, I have a CWM backup of my system but so far my attempts at restoring it have failed, even with pawitp recovery. The partition is broken so it won't take any data.
[Acer Iconia A700 and A510] Moscow Desire:
Well, that's a bit of good news. Similar to the SGS II and their leaked kernel. They had to flash a modified PIT that ignored the corrupted sectors. Lost 2gb in the process, but still a start.

Don't worry, the data partition is never actually formatted because the internal sdcard lies in /data/media. All the recovery does is delete all the files not in /data/media.
[Acer Iconia A700 and A510] Moscow Desire:
Sorry, I meant User Data/Factory Reset (as CWM calls it).

This is why when on the first attempt at restoring a recovery, the downloaded apps would not function. You had the icons, but Force Close on them all. The system apps were fine. Any attempt to restore any previous backup failed (would hang on that partition). Couldn't wipe the partition in CWM after that.

I downloaded CWM recovery image from official site as it was suggested in the first post of the thread (recovery-clockwork-6.0.3.1-a700.img), installed it by means of the standard procedure with 'adb reboot recovery' and 'fastboot flash recovery recovery-clockwork-6.0.3.1-a700.img'. Then I tried to reboot into recovery again with fastboot reboot-bootloader but it stuck on "entering boot menu mode". I cannot use fastboot commands because PC stopped recognize tablet in this mode, all the time < waiting for device >. It is not problem of the cable or PC, I tried several cables and a few computers. I cannot boot into OS because it is broken: when I reboot into the normal mode I see only CM logo, 'adb devices' shows "offline". Bootloader is unlocked.

thanks
[Acer Iconia A700 and A510] ExtremeRyno:
If you flashed CWM but did not flash a custom ROM, the next time you restart the original recovery will be there. If you flashed a custom ROM, I suppose the best solution is to flash an original ROM from Acer through CWM and the original recovery will be there when you're done. In theory. I've not tried this since the early days before Jellybean.

[Acer Iconia A700 and A510] Moscow Desire:
Stock Rom is ok, however, the usual Acer "shortcomings";

1. The wrong colored nav buttons. Why they didn't use the ICS blue to match wifi, 3g, battery and clock, well, I don't know. Color blind maybe?

2. Horrible IO performance, especially on short writes. It's almost non-existent. This is an easy fix in Ramdisk. This is something that Acer has had since 3.0.1 for the 500/501, and it's still there on their high performance device. When you get beat by a 2 core device in benchmarks, that's pretty bad... Like I said, an easy fix which I "thought" they may had fixed on the 70x.

3. GPS. Again, a simple mod to get gps lto in the ramdisk greatly improves GPS acquisition of sats. Been around for awhile.

Just some shortcomings.

i don't like stock roms in general - they tend to bloat it beyond all reason.

thats why i played with idea to buy the excite 10 since apparently it has less crapware preinstalled.

Same with my Asus - the stockrom lags and is kinda unresponsive - install termleech's aokp and it runs like hell.

The A700 is a nice pad - but with a custom rom it could be better. and since my tf300 is out of order atm i use the a700 daily @work @home and in comparison it feels like a generation behind. just my 2 cents.

thats why i hope the recov works now so that some dev with an a700 can create an aokp / aosp version for us :)

I too would love the info on the IO performance and GPS mods... :o

IMO, this tab is a bit sluggish, but it almost seems to be a touch sensitivity issue, rather than a performance issue. Just my opinion.

For the record, I am running .025 leak and have flashed the new 6.0.1 recovery successfully (unlocked and rooted). I have not yet tried to restore anything, but have (obviously) flashed at least one update to the stock .017 OEM ROM.

I would LOVE to move to CM10 and to a modified kernel, but the previously bricked devices and fracked internal memory, scare the crap out of me!!!

[Acer Iconia A700 and A510] FloOGB:
so it *should* be safe to erase /data, etc, now like we always do on all the other devices, so normal install? or do you think i should manually clear the fs and modify the installer to omit formatting?

please reply, will try this after the current run of introducing the wife to all the star trek movies ;)
[Acer Iconia A700 and A510] pawitp:
With this recovery, it has always been safe to format /data because formatting /data is coded to use "rm" so that /data/media (internal sdcard) is not removed.

This is some extra safety measures (which may, or may not help) formatting other partitions. (I had no problems formatting them, until I bricked my tablet, reason unknown)

[Acer Iconia A700 and A510] Mechkilla:
What does that mean? Did you solve your problem with the new drivers? Are there really different drivers out there? I just installed Acers USB drivers for the A70x and after that I could install CWM 6.0.1.0 with fastboot (with img-file in the same directory) from my windows machine.
[Acer Iconia A700 and A510] Moscow Desire:
Basically when you install either the Google USB or Acer USB drivers, actually several get installed to the PC. Windows isn't always the smartest apple on the tree when it comes to knowing which one to use. ;)

Usually, I check Device Manager when I have an issue with ADB, Recovery, Fastboot, etc to make sure windows chose the correct one. After you do this a few times, it seems windows gets a little smarter and knows which one to use. Sometimes, you just have to "choose from list".

[Acer Iconia A700 and A510] CheopsChefren:
In windows 7 x64 there are 3 different drivers installed for the A700: an ADB driver, a Bootloader driver, and a composite ADB driver. You can see them if you go in the device manager, and try updating ure android driver.

For - as far as i noticed now - ADB commands you need to use the ADB driver, and for fastboot commands you need to use the Bootloader-driver.

Hold volume down while rebooting to boot into recovery or use "adb reboot recovery" while booted to acces recovery. If you're running a firmware which reflashes the stock recovery, you will have to delete /system/recovery-from-boot.p to prevent that from happening.

Is it safe to back up to the internal sd card??? Can I mount a USB stick? I do not have a spare micro sd that I could use.

2)

How can I exactly do that? Using CWM? Will it prevent future OTA Updates?

[Acer Iconia A700 and A510] Moscow Desire:
Here's my theory on backing up to Internal Memory. Don't do it. Why? Well, if you get a corrupted file in one of your partitions, and have to format the internal memory, then you don't have a backup.

If I'm not mistaken, you should have an option to mount USB Ext so you can backup and install roms from USB Stick. Try going to Mounts and Storage, and mount as USB Storage. At least if I remember correctly. (my 700 still in the service center, so I'm bouncing this against my a501)

If you did not follow the instructions in the post a few posts above, then your Rom will overwrite your recovery when you boot into it. A couple posts up tell you wich file to delete from your system to prevent this.

Also, I believe it's Vol- and PWR to boot to custom recovery. Not Vol+, that usually boots to stock recovery.

MD
[Acer Iconia A700 and A510] tube:
Do I need root to delete the file? Will deleting the file prevent the subscription of OTA Updates?

I tried Vol-, but it shows the dead robot after the stock recovery is flashed (i.e. CWM has been deleted). why does this happen?

however, is there a way to get into fastboot if the system does not boot up and i do not have access to a working recovery?
[Acer Iconia A700 and A510] Moscow Desire:
Of course you have to have root AND System RW. That is, if you wish to do it from within a file explorer. So the problem, is your CWM is being overwritten every time you reboot (if you are running a stock rom).

Technically, if you want to install the CM10 beta rom, you can flash your recovery, boot immediately to CWM and install the CM 10 Rom. But, the minute you restore your stock backup, it will overwrite your CWM once again on boot.

You folks need to read and understand what you're doing and what to expect.

Of course not, it's a kernel image. You are trying to flash a kernel image into the recovery partition. And it has absolutely nothing to do with recovery.

Surprised you didn't brick your tab trying.

Told you how to get rid of CWM. Considering you have root and /System RW, why didn;t you just do like I told? If you deleted that file, you can get it from any rom listed here, and copy it in. Just set permissions like the others. Reboot. Unless you went mucking around with other files, which you shouldn't do, it should boot and wipe out your recovery.

A recovery image is actually just a kernel image with a self-contained recovery program. To get back the recovery, you can either find a dump of the original recovery image and flash it, or flash a full ROM which will flash the stock recovery once you boot into it.

The "backup" directory contains only indexes, while the actual data is stored in "blobs", where it can be deduplicated. The backup process will take several minutes stating "freeing space" before backing up.
