Recover from bad flash

Anyone needing to restore from Nandroid after a bad 4.2 flash:

Because of the reported problems with the included SuperUser.akp, I planned to flash CWM-SuperSU-v0.98.zip after JOP40C.zip, so I thought it a good idea to remove su and Superuser.apk from the zip file first, but that was a bad idea :(

Some setpermissions failed and the flash was aborted. I rebooted into it nevertheless but never got past the bootanimation.

So restore from nandroid! But my CWM touch (6.0.1.5) couldn't find the old backups. The 4.2 upgrade process had already moved stuff around the sdcard.

So while still in recovery, do 'adb shell' and restore things. The old /data/media (AKA /storage/sdcard0) was now in /data/media/0.

What I did:

cd /data
mv media media.42
mv media.42/0 media

and also clean up the new /data/user folder:

rm -r user

Now, CWM sees the backups and you can restore your latest backup.

Then flash the unmodified JOP40C.zip, CWM-SuperSU-v0.98.zip and all should be well.

From SuperSU on Google play:

So this is a bit more than Superuser provide at the moment, but still unsatisfying. I'll udpate the package when one of the superuser apps has proper support for the new multiuser feature.

Has anyone else had trouble booting into recovery on this? obviously can't do it through ROM Manager as root doesn't work, but can't do it through bootloader either.. Any ideas people?

Many thanks

How do I get TabletUI on this?
[Nexus 7 Android Development] KevinGee:
I booted into recovery just fine, I powered down completely then I held volume up and down + power button until the little android came out and then selected recovery, but you have to flash the superuser zip file that's a couple posts up to get root to work.

On another note, Is there a way to get flash working on this or not yet? Since we just have chrome and not the default ics browser like we did in 4.1.2

Have you tried installing a 3rd party browser such as dolphin? Obviously you'd need to install a Flash apk first
[Nexus 7 Android Development] laxet:
It has been removed - no tablet UI, just what the Nexus 7/10 has.
[Nexus 7 Android Development] foreman31:
yay! super su fixed and now have root
[Nexus 7 Android Development] KevinGee:
Yeah I used titanium backup to restore the flash apk because I was just using the paranoid rom prior to flashing this and I had flash working but only on the default browser and not on chrome. I did however install dolphin and it gave the same result as chrome(it didn't work). Have you got it to work, Or is dolphin working for you?

Suggestion, link should be pulled until root is working correctly on initial flash. I flashed this and while its nice to be running 4.2, would be better if ROM has su working before posting.

Thank you much! :thumbup:
[Nexus 7 Android Development] Leoisright:
Yeah, I get that. But being an experienced user AND dev for this community, its still a non functional Rom if flashing a second zip to root.

It's my daily as well. But, the point being there are too many noobs in this forum and with how different the recovery will be, this could cause more questions. It's still a great Rom, but if not rooted from the initial flash, it should not be misleading in the title. At very least change the title so it doesn't give false information by saying superuser. Cause its not

According to Jean-Baptiste Queru of the AOSP, the xoom and nexus aren't supported.... "There is no support for 4.2 on Nexus S and Xoom. Those devices should

continue using 4.1.2."

later, he says he cannot comment on the future of those devices. What does this mean for us?

unofficialy it will eventually come and it will run as smooth as nexus 10 because xoom has the capacity and hardware for it...it's not a big jump from 4.1.2 to 4.2
[Xoom General] Cubanluke88:
Don't kid yourself. The Xoom shows its age on 4.1.2 as it is. Compare the performance to a Nexus 7 or Galaxy Nexus and you can see the difference in speed. Just because the Xoom has the hardware to support the latest version, doesn't mean its going to keep up with devices with fresh hardware. Its coming up on 2 years as it is, which means a lot when there's new, better hardware coming out every ~6 months.
[Xoom General] SilentBob:
The one feature from 4.2 that I really wanted is multi user support. It was an obvious omission from tablets right from the beginning.

What are the chances of fully activating this feature in 4.1.2, seeing as it already has the underpinnings under the surface?
[Xoom General] Ianas:
Yes, it's sad, but those that say it's a "marketing ploy" just need to realize how old the Xoom is and how much work it takes to port these new releases to devices. Money doesn't grow on trees, and neither do man-hours. Once the 4.2 branch started happening and the Nexus 10 hardware was finalized it became Google's standard 10-inch tablet internally. The guys who would have been doing the port internally in Google probably have N10s on their desks and their Xooms are collecting dust in some drawer. That's the way the world works.

That being said, if you look back to ICS, the 4.0.1 code dropped... and no Xoom support. Then the 4.0.2 code dropped... and no Xoom support. It wasn't until 4.0.3 that the Xoom gained AOSP support. I wouldn't be suprised to see the Xoom supported in a 4.2.2 (or later) release. The Nexus 4 isn't even supported in AOSP yet, for goodness' sakes! It will probably be someone's 20% time project and it will happen eventually.

Either way, if it doesn't hit AOSP, I'll either sell it to get some dough for a N10 (my mom has been talking about buying it from me) or lend my support to the porting process during the holiday break. The multi-user mode in 4.2 would be very useful on the Xoom.
[Xoom General] romdroid.:
dude dont be a ****ing noob, its not the "core" that matthers.
[Xoom General] Cubanluke88:
Thats a bit of a hostile response, don't you think?

And if by "core," you're referring to the SoC, yeah it kinda does matter. The tegra 2 is a tad outdated, its architecture being a big part of it (A9). The Tegra 3 was a nice upgrade on Nvidia's part, with the Samsung Exynos 5 being even better than that. I'm sure someone with even more technical expertise could explain more in detail on the differences, but the architecture itself is a good indicator.

Now on to personal experience. I've put my Xoom alongside a Nexus 7 and my Galaxy Nexus, all running 4.1.2 and yeah, the Xoom is noticeably slower. I can't wait to see the Nexus 10's performance in person. No one here is saying the Xoom is **** or slow or whatever. But it is, gasp, slower than devices with hardware that is fresh and not 2 years old. Newer technology is better, who knew?

So yeah...no offense but given the delightful way you went about disagreeing with me, I'd say you were projecting just a tad.

---------- Post added at 05:33 PM ---------- Previous post was at 05:28 PM ----------

The difference with those instances and now is that the Xoom was projected to get all of those, it just took a bit of time for it to hit AOSP. According to the google groups statement, the Xoom is slated to stay on 4.1.2 (I forget the actual quote). Now of course, that could mean, as you say, that it might just be a while for it to hit AOSP, but I think that's being a bit hopeful. Hopefully we'll get an official word on it soon but I think thats about it, at least with regards to AOSP.

And honestly, the Xoom had 18+ months of official support. For those that remember, 18 months was what Google wanted manufacturers under the Android Update Alliance to go by for supporting devices. So they've met their own target and then some with regards to both the Xoom and the Nexus S.
[Xoom General] alex94kumar:
It would be nice for the Xoom to have 4.2 support, but even if it doesn't happen, its been a fabulous 2 years, right? Because I think it has

It has been a fabulous 2 years, we'll still get 4.2 support, just unofficially

AOSP not supporting Xoom

No a very smart move by Google, me thinks, in not supporting Xoom after 4.1.2 ( Bless the custom mod gurus!!!). I know in my case I am going Windows Surface. Heres why, I just updated my 6 year old notebook to W8, and it flies.. new lease on life. If Google think I am buying a new tablet every 2 years, Stop the train, we have arrived at looney (google) central!!!!. Long live the custom rom(ers)
[Xoom General] Cubanluke88:
The thing is, 2 years is actually...kind of a lot relative to the other first gen 10" tablets. The galaxy tab 10.1 took forever to get ICS and was put at EOL after that (back in June/July I think). Asus has handled the Transformer series pretty well; the OG Transformer received a timely ICS update and I believe was updated to 4.1, not sure if they're going past that. And finally the Acer A500 I think met a similar fate as the Galaxy tab, ending with 4.0.

So that puts the Xoom at one of 2 of the 4 Honeycomb tablets circa 2011 (were there any other notables?) that made it all the way to 4.1. Not too shabby.
[Xoom General] Lothaen:
Not shabby at all. A shame though that the reason for not supporting is a time limit instead of a hardware thing.

Phones changed a lot since nexus one to ICS

Not much changed hardware wise since Xoom and now IMO
[Xoom General] bigrushdog:
As I type, somebody is building 4.2 for the G1. Look, we can take anything aosp throws at us and make it work on Xoom, to one degree or another. It becomes a matter of performance. At some point, a previous aosp build will just be better for Xoom than the newest build.
[Xoom General] Muffycheeks:
So does this meanTeam Eos is finished with rom support for the Xoom?
[Xoom General] Winesnob:
Just found in this thread http://xdaforums.com/showthread.php?t=1997434 that the system partition on the Xoom is rather small-could this be the reason that Xoom fell from AOSP support and didn't get all of the JB features?

Updated my tablet to Android 4.2 this morning and afterward watching video with Bluetooth headphones it's skipped popped and just been generally awful. Curiously music works fine. Anyone else experiencing this?
[Nexus 7 Q&A, Help & Troubleshooting] sark666:
I just tried a few mp4 clips and didn't experience any skips/lag. Can't try avi right now as mx player doesn't work in 4.2 However, it seems there has been some changes to bluetooth. If you have your volume loud enough you can hear it 'stop' using the bluetooth if idle for a couple of seconds. Never heard that before. Also, a bug that really irks me is latency with bluetooth in games. Previously, games like dead trigger would seem to lag well over a second behind, almost 2 seconds. Now it's about .5 of a sec, however it's skips,scratches etc.

Other games fair better. For example, mame has about .5 of a second where it exhibited the 2 second lag previously. Not nearly as many skips as dead trigger but I heard a couple.

Btw, is android the only platform that has this issue? I read old posts of ipad's/iphones having it back in 2009 but I believe they fixed it. My friend has a playbook and it didn't support bluetooth stereo profile (ad2p) but they released an update last year and it works perfectly. I tried a few games on his device and none of them exhibited any lag, scratchiness etc. So RIM gets it right the first time and google has had this issue on all their devices for years? There's a few bugs filed on this on the official google bugs forum opened in 2009 and no response from any developer.

EDIT:

Just tried youtube with bluetooth stereo headset, audio breaking up, stops/starts. It seems to be going quiet if there is even a moment of silence in the video. God damn it, I use this all the time and now it's unusable. This was at least one thing that worked fine with bluetooth. It could be my connection right now but I highly doubt it. I'm at home and this connection is always fine, this is the first time I've experienced this. I bought this headset for gaming, videos, and voip. Voip didn't work because bluetooth mics are basically non-usable in android, gaming has lag, and now videos won't play properly. I think it has to do with using the wifi at the same time with videos as videos downloaded from youtube are fine.
[Nexus 7 Q&A, Help & Troubleshooting] robyr:
Yep this mimics my issue. Streaming anything results in choppy playback over Bluetooth. This really is not acceptable to me, and its hurting my view of my nearly brand new Nexus 7. I really hope we see another OTA seeing as I can't very well turn WiFi off on a device that relies on WiFi.
[Nexus 7 Q&A, Help & Troubleshooting] nolig2278:
I have the skipping too with Pandora over blue tooth, but thought it might be Wi-Fi limit since I am tethering off my rezound which is playing flawlessly over BT. It was skipping as pictures loaded in emails.
[Nexus 7 Q&A, Help & Troubleshooting] robyr:
It isn't WiFi bandwidth related as far as I can tell. I can buffer a video, play it, and still the audio flips out. This is just disappointing and sad on Google's part now. The same issue affects the Galaxy Nexus, as well. Did no one even bother to test this before it rolled out??
[Nexus 7 Q&A, Help & Troubleshooting] purudaya:
I've been having the same problem since the 4.2 update - the bluetooth issue is definitely linked to wi-fi (no skipping on downloaded video while wi-fi off; skipping as soon as I turn it on). Online bluetooth streaming of any audio whatsoever is basically ruined.

I thought maybe changing the channel on my router would to the trick, but no dice. Google was very sympathetic over the phone but completely unhelpful - "this is the first we've heard of this."

I've only been an android user for a few months. Are they usually pretty good about addressing stuff like this?

bluetooth now working

My bluetooth headset (Samsung) was stuttering the other day as many people are reporting. I did play around with the settings and at this point I have no idea why, but it is working fine.

I had done 2 things:

1. I unpaired every device and re-paired them

2. On the wifi advanced settings, I set it to never sleep and disabled battery optimization

Bluetooth then worked fine using Pandora and TuneIn radio. I changed the advanced setting back to optimize battery and all still works.

Now extremely happy with 4.2 but baffled as to why it now works.
[Nexus 7 Q&A, Help & Troubleshooting] sark666:
I am going to test more but I read it from someone else and it seems to have helped me, is to disable gps. Others said it didn't work for them so maybe it depends on the bluetooth device as well. But with gps disabled youtube no longer lags/skips and stays in perfect sync, but I'm going to test more.

And with gaming, it's almost in perfect sync, however some games still skip a bit and some lag more than others (mame4droid seems to lag the most). Whereas before 4.2 all games had almost 2 seconds delay in audio.

So in some ways, bluetooth is actually better in 4.2 in that they seem to be closer in getting the lag in realtime apps (games) working. So I hope their fix is not to simply revert to 4.1.2 bluetooth.

Anyway, try disabling gps, it may work for you.

To all those who are trying to use Wi-Fi & Bluetooth, Good luck!

It is not BT that is broken in 4.2!!!

First of, 4.1 was working fine with my BT audio, got the OTA update and it was still working fine after first reboot... couple of days later mine started to act up...

It was almost impossible to listen to BT audio... but BT is not the problem!!!

It is either the Audio Effects service/program or Google Music... easy to test...

Connect the BT audio device, go into settings, apps, running stop the Google music service, stop the audio effects thing... BT audio does not skip at all anymore... It is as flawless as it was in 4.1... so the BT is not broken i any way... it is either the audio effects service or the Google music stuff...

I hope someone will fix it... but it is not BT that is bugged...

I'm sure I should know the answer to this....

Am I rgiht in thinking that THE ONLY WAY to copy files to the Nexus via OTG is via Nexus Media Importer?

I have a rooted N10 32gb, with an OTG cable that works well on NMI, but USB sticks / SD cards don't show on file explorers.

It's not a big deal as dropbox does pretty well on it's own - I just wanted to make sure.
[Nexus 10 Accessories] BoneXDA:
