Congratulations, it unfortunately can not test because I have an A510. Is the recovery from a510/a700 the same? Actually, the tablets are different only in the display, right? Has anybody tried to flash a recovery from an a700 to a A510? Where did you get the two files, especially the fstab?

Thanks!

Thanks, have you fully tested it ? We've had a couple of recos that managed to bricked tablets so far :D

Edit : you have not tested the wipe ? Those one bricked my A700 so be careful.

Thanks!

The boot.img was dumped from my device using dd, recovery.fstab was based on Nexus 7's and modified to suit our device. I'm not sure about the A510 since I don't have one.

Wipe works both from system and recovery itself.

OK thanks for the info.

Too bad my tablet is still unable to boot :(

Are you able to boot into fastboot? Are you able to boot into recovery using the orientation lock + volume down + power?

EDIT: Oh wait, this device has no way of booting into fastboot without a working system?

Just checking procedure please....

I got the OTA update today to Image version: Acer_AV043_A700_RV07RC06_PA_CUS1 Build: Acer_AV043_A700_1.029.00_PA_CUS1

I had to unlock the bootloader and root again. ***OTA Rootkeeper WILL NOT keep the root! The bootloader is re-written and root removed***

I just downloaded the Recovery.img file and want to be SURE I do this correctly, so please forgive me if I sound "noobish"!

1. Copy Recovery.img to root of SD Card
2. Use ADB Fastboot to get tablet into flashboot mode
3. Once tablet has entered flashboot, Type -fastboot flash recovery recovery.img
4. Process should allow me to enter Recovery mode

Am I correct here? I don't want to brick my tab! I appreciate any input and thanks in advance!:)

Well we don't have a fully working nvflash for tegra 3 with sbk support yet. If you have one I'm interested :D

Did you check the a700 service rom? It seems it has the NVFlash support as near as I can tell. Should be the same for the 701. Looks like it has support for the blocks.

I can't do anything with it. Tab is still in for repair. Hope maybe this week,

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!

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.

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.

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.

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.

And that basically clears data. I've tested it, it works (and mentioned it on first page).

    Thanks to the kernel source that FloOGB has requested from Acer, we have have a safe Jelly Bean compatible CWM (see first post).

    I am nuts! I did everything wrong! I forgot that to enter fastboot mode I need to toggle several times lock switch after releasing power key. Sleepless night, you know... Now everything all right. Thank you very much!

    Recoveries on the official site is now working again and I encourage everyone to upgrade since it contain updates including:

    - SELinux support (required for full compatibility with CM 10.2)
    - NTFS and exFAT support for sdcard in recovery
    - USB-OTG support in recovery (backup/restore/install ROM from a thumbdrive)
