Errors

Ok, on a 701 which should be the same as a 700.

Can't boot to recovery using PWR and Vol + or -

Can only boot to recovery using ADB,

Can't do a backup, because;

Can't mount /cache

Can't mount Dev/Block

No such file or directory. Too many can't mount errors.

Any guesses?

I have a feeling because it's because of the root.img from here.

However, the CWM should be running independant.

Not to mention, the file you download, is not the same in your instructions.

[Acer Iconia A700 and A510] DЯΦiDi@П:
First: key combination to get into recovery changed with JB as I mentioned here.

Next: With JB on the tablet you need a CWM compiled with a JB Kernel.It works fine on my A700 to flash.
[Acer Iconia A700 and A510] pawitp:
Please remove the link. Unpatched "jellybean" kernels are dangerous and may/will brick your device.
[Acer Iconia A700 and A510] pawitp:
Are you running on jellybean bootloader? They have apparently changed a few things. Please attach a full dmesg from recovery.

As for the filename, anyone wanting to run a custom recovery should be able to at least rename a file ;)
[Acer Iconia A700 and A510] Moscow Desire:
Funny guy :p (there's always a comedian in the crowd). Ok, I had that one coming ;)

Was thinking maybe I missed something :confused:

Anyhow, yes, it's the JB Bootloader.

Tried getting a dmesg while in recovery, unfortunately, no-go. Adb doesn't see the tab while in recovery. Unless you know some specific adb command? If so, I would appreciate it.

I can get a normal dmesg after tab boots. Probably won't do you much good.

MD
[Acer Iconia A700 and A510] Moscow Desire:
Now, the reason we would like the link removed, is because the JB kernel used contains a "super-brick" bug. If it hasn't been modified with those portions of code removed before adding it to CWM. Yes, it appears to work fine, however, it's a disaster waiting to happen. It has been removed from XDA before about 2 weeks ago because it bricked tabs.

Example: Go into your CWM, and do your wipes (user data, cache, dalvik, and then do your formats , Data, System, Flexrom)

Then, do your restore from your backup.

Tell us if it works.

In the meantime, please remove the link, or I can have the FSM do it.

Please don't take this the wrong way, as we appreciate contributions to the community. However, I advise not to post links to known Brick programs until the bugs have been worked out of it.

MD
[Acer Iconia A700 and A510] DЯΦiDi@П:
Im rather sure, that this is not the same version, than the one here on XDA from a .ru(?) site. But due to unfinished testing I remove the link as you requested. (But it was no good idea to quote my post, because I can't edit your post ;) )

Sadly without this recovery, flashing of unsigned files unter JB is not possible...
[Acer Iconia A700 and A510] Moscow Desire:
Really, no offense intended ;) As you may have known from the past, we had several bricked tabs with the zero-null recovery, then another one came along a couple weeks ago, and bricked on trying to restore a backup.

As with what you have, there needs to be more info about it, because right now, it's just a JB Recovery image. I will send you a PM in a little while, so you can explain it better..

I read about the CWM 6.0.1.1. from 4pda.ru and thought it was a bug in this particular version. The one I postet was build on 3rd October as a result of a support thread in a german forum and is based on CWM 6.0.1.4. But I must agree, that it was no good idea to distribute it, while it is not fully tested.

Nevertheless I leave the link in my HowTo but added a description according to the situation.

Hey guys,

i have a rooted A700 with the 2. method of this thread http://xdaforums.com/show....php?t=1727105 . Now i want to install JB, but normal update wont work because of rooting the device, since then i am forced to use CWM. I tried the CWM-based Recovery 6.0.1.4 but getting error "FAILED (remote: (00120000))" when i flash it via fastboot. Note Bootloader is unlocked!

I then tried to flash the stock-recovery, because i thought the rooting might have overwritten something, but i get the same error.. i searched for the code, but didnt find anything which could lead me in a direction to search for the origin of the problem..

Hope any of you guys can help me..
[Acer Iconia A700 and A510] :
You have to install the Stock 4.0.4 Rom from the JB-Thread first to update it. Just follow the instructions from the "A701 4.1.1 [JB] OTA Firmware. UPDATE: FULL 4.1.1 and ROOT - xda-developers" -Thread ;)

So I can flash the CWM 6.0.1.5 from first post even though I´m using CWM 6.0.1.4 and the actual nightly Builds. After flashing the new CWM I can continue wiping Data and cache before installing new Jelly Bean builds without bricking my device...:rolleyes:

Getting from stock to CW10...

pawitp,

I was originally rooted on the ICS and running the leaked JB build you helped provide, I decided to go back to stock and wait for the official USA JB build to be released, so I could pick it up as an OTA.

I did all that and now want to re-root and go back to CW10 Nightlies. I have downloaded the new recovery (Thanks to FloOGB for the code!!!), and unlocked the bootloader, but even though I can flash the new recovery, I can't get it to stick AND the root method listed in this thread (http://xdaforums.com/showthread.php?t=1727105) says for ICS firmware only, which I gave up when I went to the OTA JB.

Can I flash the boot image from the Nighltlies build, instead of the boot.img that is in the root patch, to get root?

Will that allow me to flash the new recovery?

Sorry for what seem like NOOB questions, but this is the first time I haven't been able to read through the forum and find my answers.

Again, thanks for all your hard work on the A700. Looking forward to seeing what the dev community has in store.

Thanks,

bucklyv
[Acer Iconia A700 and A510] pawitp:
Yes. CM version and CWM version are independent.

No, you cannot use a boot.img from CM in stock ROMs. If your sole purpose is to run CM though, just to "fastboot boot recovery.img" and flash CM from there. Then you can flash recovery later.
[Acer Iconia A700 and A510] bucklyv:
Wow... that is way easier than I thought it might be... Doing a nandroid now, then on to Nightlies... :D

Thanks for the quick response!

bucklyv

EDIT: So, I got into CMR and made a nandroid, Then I installed the CM10 nightlies build, but I am not stuck at the ACER splash screen. I cannot get tablet to respond to either ADB or FASTBOOT commands, though I know the computer is recognizing that I have attached a device.

Any thoughts? Any help you could offer would be most appreciated!!!
[Acer Iconia A700 and A510] pawitp:
Sounds like you're stuck in APX mode (check device manager). If you are indeed in APX mode, you are probably out of luck. You've used the CWM in the OP of this thread right? What is its filename?
[Acer Iconia A700 and A510] bucklyv:
The file was "recovery-a700-6015"...

The exact steps I followed were:

fastboot boot recovery-a700-6015

nandroid to ext_sd

factory reset

wipe system from advanced menu

install from ext_sd CM10 nightlies 2012-23-10

reboot

it seemed to allow access through adb at reboot, but then just froze.

My device manager shows the A700 as connected (error code 10) "Device cannot start"

????:crying:
[Acer Iconia A700 and A510] pawitp:
If you can access adb at any point in time, then it's not yet a hard brick. Try using the key combo (hold power + vol down, release power when screen display, change to vol. up when tablet vibrates the second time) to access recovery.
[Acer Iconia A700 and A510] bucklyv:
Whew... okay, made it back to the ACER recovery screen, then fastboot, then CMR...

I am going to restore the nandroid, the reboot...

Thanks!!!!

I guess the only outstanding question is: "how do I actually get to CM10?

Again, thanks for our help!

EDIT: I was able to restore the SYSTEM partition, but got an error when it got to data... it rebooted just fine, but I have not tried to open anything yet. Thanks again!
[Acer Iconia A700 and A510] pawitp:
Talking about data, did you wipe /data after installing CM? It is required.
[Acer Iconia A700 and A510] bucklyv:
Actually, I tried wiping data before and after installing the nightlies build, with the same result... always gets hung at the ACER splash screen... boo... :crying:

The strangest part of the whole thing is not being able to restore data. I get the same error with every try: "Error while restoring /data!" :confused:

EDIT: While I can still not restore the data partition, I have been able to get the tab to boot into the CM10 splash screen... It sits there for as long as I let it. I have formatted before and after to no avail...

My steps are as follows:

From OEM JB setup...

adb reboot bootloader

fastboot boot recovery-a700-6015

format cache

format dalvik cache

format system

format data

install from ext_sd 2012-23-10 CM10 nightlies (I have also tried CM10 2012-23-10 experimental kernel nightlies)...

format data

reboot system

It goes to the CM10 boot screen and spins forever...

Any thoughts???

Try downloading some apps from the play store. See if it downloads and installs, or it errors out.

MD
[Acer Iconia A700 and A510] bucklyv:
Okay, I'm getting ready to try it... what are my scenarios for if I can or cannot install apps from the market...??? Just curious???

Thanks pawitp and MD for looking out for us...

EDIT: Well, the Play Store crashes every time you try to download, update or uninstall anything. If you clear cache and data, you can go back in and browse and move between the different tabs etc... but you cannot modify anything. Amazon App Store is fine, and under settings, the available storage on both the SD and ext_SD are correct.
[Acer Iconia A700 and A510] Moscow Desire:
Well, I really don't even want to go there...... I remember my 701 brick over 3 months ago. Same scenario but with the original bad CWM.
[Acer Iconia A700 and A510] Moscow Desire:
Can you uninstall from Settings? And you're saying Amazon App store downloads just fine?
[Acer Iconia A700 and A510] bucklyv:
Actually, I went one step further. I uninstalled the Google Play App altogether, the restored an old copy using Ultimate Backup Pro... without doing data, now it is working again.

As for the Amazon App Store, it worked just fine, even when the Play Store was FC'ing.

The only thing I can figure, is when I tried to install CM 10 I flashed the new gapps zip from the CM10 site and this caused my Google apps to get borked...

Anyway, I would say the new recovery did not cause any of those problems, but it will still not let me go from the stock ACER JB, to CM10... :(
[Acer Iconia A700 and A510] Moscow Desire:
I'd say you dodged a bullet this time. ;)

I'd play around for a few days, just to make sure things are in order.

Generally, before installing a new rom, it's usually standard procedure to Wipe Data/Factory Reset, cache, dalvik, flexrom and system. This generally cleans all data from the partitions in order for a good install. If there's an issue with this working correctly, then theres a problem somewhere.

But it seems the 51x and 70x are very sensitive in this regard.

Glad to hear you're still up and running!

MD
[Acer Iconia A700 and A510] Vorbeth:
One issue with nandroid I can see is that /data holds the internal sdcard.

This could be the cause of nandroid not working correctly.

When backing up will be trying to backup the actual nandroid file, also on restore it will delete/wipe data removing the actual nandroid backup.

I've not really played with CWM on here too much yet.
[Acer Iconia A700 and A510] bucklyv:
Thanks, you and pawitp are great for helping out!!! I have now installed and uninstalled a couple of apps, big ones just to make sure, and had no problems... even went and tried to open the other apps that would have been updated when I flashed the gapps package, and everything seems to be fine.

So I guess I still have the same question(s):

- I am pretty sure I followed the proper steps to wipe and load the CM10 nightlies build, so why can't I get pas the boot screen?

Again, to be clear: using the latest CMR 6.0.1.5 (verified that three or four times for myself), I wiped everything that could be wiped using the advances tab and the format command, installed the 2012-23-10 CM10 build, installed gapps, re-wiped data and cache, then rebooted. I tried this with both the original nightlies build and the experimental kernel build. Both get me a very Stargate SG-1 looking boot screen, but that is as far as I get.

...then, when I manually go back into CMR (fastboot boot recovery-a700-6015.img) and try to restore my nandroid, it says it cannot restore the data partition.

What seems the most odd, is that when I finish the restore and reboot, all my data is still there... :confused:

I even tried restoring the nandroid I made of the OEM .057 ICS from Acer, but couldn't get it to load on the new firmware. So, now I can't even go back to the pre-OTA-JB build of ICS and re-root, to load CM10. UHG!!!

Oh well, I'll keep reading and maybe something will just come to me... LOL!

I would probably guess the Install Script.Probably might be a good idea to compare install scripts between the 700 and 701. This are a little different from installing on the older tabs. Probably some build.prop edits as well.

Unlocking your bootloader...
[Acer Iconia A700 and A510] Moscow Desire:
That, and isn't there one of those nasty "boot-recovery". script files that needs to be deleted from the stock systems? Or else it re-writes your CWM with the stock recovery when you reboot?

At least it was on the 50x ICS.

MD
[Acer Iconia A700 and A510] FloOGB:
There is a quick workaround for that

adb reboot-bootloader (or another way to get into fastboot mode, like button pressing etc)

fastboot boot <cwm-recovery-file>

that boots you *once* into CWM without modifications to your device. There you can flash another ROM (if you want to)

Hi!

Made a backup with 6.0.1.5-touch yesterday, but it was only about 150 MB in size. A Backup from my DHD with a similar amount of apps is about 1,3 GB and JB rom itself is about 250 MB. So what's wrong here?
[Acer Iconia A700 and A510] casper326:
Already unlocked....
[Acer Iconia A700 and A510] paugustin:
Then justice look at Moscow Desire message. There is a function that overwrite the recovery with a stock one.

When you reboot in CWM it should ask is you want to disable the recovery overwriting.
[Acer Iconia A700 and A510] bucklyv:
Okay, so after all that I was able to get CM10 loaded, but I know it is not wiping correctly!!!

All the relics are still there from the iconiaN ROM used to achieve root. I have tried wiping data, system, sd_card (not external_sd), cache, etc... on multiple occasions, including the factory reset.

I am not sure how to get adb to work inside recovery, but I did run the "show log" function and got the following:

rm: can't remove 'tombstones': Read-only file system

rm: can't remove 'user/0': Read-only file system

rm: can't remove 'user': Read-only file system

Done.

I:Can't partition non-vfat: datamedia

I:Can't partition unsafe device: /dev/block/mmcblk1p1

I:Can't format unkown volume: /emmc

E:unknown volume for path [sd-ext]

rm: can't remove '/data/dalvik-cache': no such file or directory

rm: can't remove '/cache/dalvik-cache': no such file or directory

rm: can't remove '/sd-ext/dalvik-cache': no such file or directory

Dalvik Cache wiped

I think I have a guess what some of that means, but not sure... MD, pawitp, any thoughts?

[Acer Iconia A700 and A510] ExtremeRyno:
My issue is that I can't get CWM to actually install. I've followed the steps in post 1, but when I go to recovery it is stock recovery...Then I have to reboot into fastboot and do fastboot boot recovery.img to get to CWM.

Any clue what I'm doing wrong, here?
[Acer Iconia A700 and A510] bucklyv:
pawitp,

I have a theory about some of the issues folks are having flashing ROMs with the new recovery.

The rooted boot and flexROM files from the iconiaN project ROM have been great for getting root, but the installation of future ROMs (of any flavor) have relics from old installs.

You cannot delete/wipe/format the /data partition in the 6.0.1.5 recovery. No matter how many times you execute the commands in recovery, it doesn't happen.

By setting the recovery to NOT delete the /data partition, in order to avoid the super-brick, you keep it from deleting enough of the data to actually clear the parts of /data that need to be fully wiped.

Not sure how to fix it, but I can absolutely guarantee /data is not getting wiped correctly.

Happy to help if I can.

Thanks for all your help!

---------- Post added at 10:18 PM ---------- Previous post was at 10:12 PM ----------

That is the same problem I had as well.

The question comes down to why do you want to install the new recovery... once the rooted boot and flexROM images are flashed, the recovery can be permanently flashed as well.

Look at the files posted in the iconiaN project thread.

No matter what, always do a nandroid first... but as far as I can tell /data cannot be restored with any JB recovery, yet... even the new 6.0.1.5!

There is something going on...
[Acer Iconia A700 and A510] Vorbeth:
If you look at the iconiaN install script, you will see instead of formatting /data it runs a bash script that does a recursive delete on /data removing all but /data/media

Maybe implementing something like inside cwm would help
[Acer Iconia A700 and A510] pawitp:
That is exactly what CWM does (except it not being a bash script) and it worked on previous versions, I haven't investigated what's the problem with the latest version yet. (So many things to do IRL)
[Acer Iconia A700 and A510] bucklyv:
Agreed.

Another option would be to develop a "super wipe" script for the A700 that could be flashed as a separate zip file when needed. I ideally you would have it work inside an installer like aroma and would be able to select which partitions to wipe.

Of course I am just starting to learn any of this... I am pretty good at being able to read a file and figure out what it does, but creation of the file is still way beyond my abilities.
[Acer Iconia A700 and A510] pawitp:
I have tried wiping and it worked just fine on my device. After a "failed wipe", while inside recovery, use adb to get /tmp/recovery.log and post it.
[Acer Iconia A700 and A510] bucklyv:
I think that it one of the problems, the wipe doesn't fail, CWM sees it as successful... none the less, I will pull the log.

Layer 8 problem. Post deleted.
[Acer Iconia A700 and A510] farazjk:
Is this only for A700 or will it also be good for A701?
[Acer Iconia A700 and A510] paugustin:
I think pawitp said that this should not be used to flash ROMs on A701 as partition mapping might differ betwee A700 and A701.

Still the recovery will install fine and I used it to flash a superuser to my system. I made a backup but haven't tried restoring it... so I don't know it it will work fine.

[Acer Iconia A700 and A510] Vorbeth:
@pawipt

I noticed in the device tree on github you have a value of

length=-1081344

for /data

In both the A700 & A701 stock recovery that value is

length=-1048576

Also this recovery should be fine as both devices recovery image and actual kernel config are the same in the stock jellybean ROMs.

Only init.usb.rc differs in the boot.img.

All other differences for 3G etc are in the actual system files.
[Acer Iconia A700 and A510] pawitp:
The value I used was from my copy of the ics ww stock ROM (or so I believe), but it doesn't actually matter since the partition is never actually formatted.
