The Problem is, that i dont have a external sdcard. That means i cant flash the bootloader trough cwm...and the system img also not... **** it
[Xoom Android Development] Ash09:
Could somebody PM me the 4 files please too?

Thanks in advance!
[Xoom Android Development] jim_panse:
And did you flash the bootloader patch for the Verizon 3g Users?
[Xoom Android Development] Marshall1975:
Lowtraxx

Hello

Im thinking the next best thing would be to obtain a new set of 4 files, maybe ones without a proxy server set. I dont know if its relevant but this only happens on 3g not on wifi
[Xoom Android Development] lowtraxx:
jim:

Yes, I flashed the bootloader patch and the new boot.img.

Marshall:

I dont know if there are differences between the database files from different carriers and that this did something to your settings. I am not sure where else the Android Browser has proxy settings. I found out how you can query the settings db directly for proxy settings. But you need to know your way around adb and sqlite.

> adb pull /data/data/com.google.android.providers.settings/databases/settings.db settings.db
> sqlite3 settings.db
sqlite>.dump system
sqlite>.exit

It should show you all the settings in the system settings db. If the field http_proxy is set you have to remove it and push the db back. So if thats to great a hassle you propably should get the files again.
[Xoom Android Development] Marshall1975:
Lowtraxx

Thanks for that. Am certainly happy to give it a try.
[Xoom Android Development] jim_panse:
Okay, i will flash everything trough fastboot... let's see, if it works.
[Xoom Android Development] kristian82:
Hey,

great to see improvements on the Euro 3G Version.

Is there a possibility to get back to stock ROM and relock the Euro 3G Xoom?

I don't feel comfortable flashing theupdate without having the chance to get back in case of failure.

Greetings,

Kristian
[Xoom Android Development] jim_panse:
Till now theres no way to relock it. We dont have the original stock files from motorola.
[Xoom Android Development] marekpipe:
can somebody pm or post the three database files of a euro xoom?

Seems that one file was not copied right and now im on 3.1 without 3g ...

I copied them by adb pull ...

Thanx
[Xoom Android Development] B3rlin3r:
we have the stock image and after you flash it, it will be locked....

[Xoom Android Development] jim_panse:
Those files dont relock your device. If you try it, you may be ending with a brick.
[Xoom Android Development] B3rlin3r:
I used this files and end up with a locked 3.0.1...
[Xoom Android Development] jim_panse:
Did you fastboot oem lock?
[Xoom Android Development] B3rlin3r:
I used this files:

http://www.megaupload.com/?d=9UOCTW71

archive with 3 files:

system.img

recovery.img

boot.img

flashed with fastboot
[Xoom Android Development] jim_panse:
Yes, but that doesnt mean you relocked your tablet.
[Xoom Android Development] B3rlin3r:
No, after flashing it was locked. Before I've got a rooted verizon 3.1 3g(unlocked)...
[Xoom Android Development] jim_panse:
How did you check that?
[Xoom Android Development] B3rlin3r:
Wie meinst Du das? Also nochmal. Ich hatte ein rooted 3.1 verizon 3g img per CWM installiert, bis dieser thread gestarted wurde. Um an die Db-Files zu kommen habe ich die 3 img per fastboot installiert(danach mit CWM ein factory reset gemacht). Nach dem reboot hast Du dann ein gelocktes 3.0.
[Xoom Android Development] jim_panse:
Ja, das ist alles richtig soweit. Aber nur durch das flashen durch fastboot, ist dein Tablet nicht wieder gelockt. Du kannst jetzt wieder flashen was du willst mit fastboot. Um richtig zu locken, brauchen wir die SBF Files von Motorola.
[Xoom Android Development] B3rlin3r:
Ich weiß nicht was '"richtig locken" bedeutet. Ich vermute etwas mit Original-certs. Jedenfalls hatte ich mich gewundert, wieso ich das Gerät mit "fastboot oem unlock" wieder rooten musste nach dem flashen. - Wie auch immer, danke für die Info. :)
[Xoom Android Development] ed.dark:
English please gentlemen
[Xoom Android Development] marekpipe:
Perhaps to make it clear:

3G works only (in my case with a tmobile xoom) after flashing 3.1 with all steps but not the 1st (recovery). I had to do step 4 which is only for verizon ... after that i adb´ed the four files and after rebooting the 3g was found. without step 4 there was no 3g found...
[Xoom Android Development] ed.dark:
Can anyone confirm if the scrolling in the home pages and browser is smoother with 3.1?
[Xoom Android Development] marekpipe:
is it possible to flash tiamat kernel for overclocking after that or not?
[Xoom Android Development] marekpipe:
3.1. runs really smoother... with the language pack 0.5 you have 3.1. with full german support
[Xoom Android Development] jim_panse:
Yep, i have latest tiamat running. Just follow the instructions in bis thread. I flashed the Boot.IMG for the verizon 3g and it worked
[Xoom Android Development] DanS:
Am I going to lose all my settings and installed apps if I follow this guide and update from rooted 3.0.1 EURO 3G Xoom to 3.1?
[Xoom Android Development] lowtraxx:
Yes you will loose all programs and settings, but the data on /sdcard (internal storage) stays intact.
[Xoom Android Development] Marshall1975:
lowtraxx

I have to admit defeat now as no matter what I do I cannot get 3g working properly and have never managed to get books lol. I think without the settings files pulled from a UK 3g xoom I'm pretty much knackered.
[Xoom Android Development] shmigao:
did that and now cannot connect to WIFI. it says "connecting" then "obtainning IP address", but doesn't succeed, goes back to "connecting" and the tries another AP

have spent the last 1hour to fix it, but reflashing any kernel does not fix it

:(
[Xoom Android Development] Riffer:
@topic starter: you should move the adb push of prop file to step 4 because you have to adb remount to do this.
[Xoom Android Development] lowtraxx:
shmigao: Have you tried pushing the bcm4329 module for your kernel back. I heard this could lead to WiFi not working.

Riffer: Thanks, moved it to step 4
[Xoom Android Development] shmigao:
hi thanks, this could help... i can find the command lines in the tiamat thread, but not the files anymore...

do you have them handy?
[Xoom Android Development] lowtraxx:
Nope, sorry. I also dont have my XOOM Handy. I could adb pull it for you tomorrow once I am at work.
[Xoom Android Development] mcfisch:
My 3G became very unstable. It works for a while, then it stops and the SIM-Card doesn't seem to be detected anymore. Then no more networks could be found and I have to reboot to fix it. Wi-Fi seems not to be affected by this issue.

I've installed Tiamat 1.4.2 @1.4GHz, but the problem appeared before that, so I doubt it has anything to do with it.
[Xoom Android Development] shmigao:
2nd try Tiamat flash no WIFI again............... and i am certain i did right

will use HC3.1 without the kernel first
[Xoom Android Development] sandro.bertini:
Hi Lowtraxx and people.

Just did it in my Brazilian Xoom and it worked great. Wifi and GSM work great, testing now for stability and speed. Also flashed tiamat with no problems.

Thank you for the great guide.
[Xoom Android Development] lowtraxx:
McFish: Hi, i had it now running for 4 consecutive days and my 3G is still rock stable. If you have 3G Problems, could you attach a logcat when they occur, maybe I see something.
[Xoom Android Development] mcfisch:
Here you go...
[Xoom Android Development] Marshall1975:
hello

Does anybody have the build prop and 3 settings files from a UK 3g xoom as the German ones another member gave me cause problems with the 3g. My xoom is on 3.1 at the minute so I'm unable to get them myself.

Thanks
[Xoom Android Development] lowtraxx:
McFish:

How often does this occour?

Do you see any kind of pattern to it?

Is it possible you had set the "Use only 2G networks" setting in your settings db (Or if you got it from someone they in theirs)?

Did you create your build.prop yourself or did you use mine?

When you made the logcat, the 3G was already gone? If so, could you keep it running while 3G is working and send it once it stops to do so?

Also in the trace i see a RADIO_NOT_AVAILABLE Exception which leads me to belive that either something with the links to the modem in the build.prop is not okay or some of the network related settings in the db are messed up and once one of them is queried the Radio crashes.
[Xoom Android Development] mcfisch:
Ok, let's go through these points...

1. I can't really see a pattern, instead of after wakeup in the morning (at first me, then the Xoom :D) and switching off WiFi before leaving home 3G isn't available - the same on afternoon when leaving work. ATM I'm trying to provoke the error appearing, but it seems it won't happen today...

2. "Use only 2G-Networks" isn't and was never set to "active".

3. I've pulled my own settings before I was going to flash the tablet and pushed them after finishing the upgrade process.

4. I used your build.prop. Can't built an own one currently, my original 3.0.1-conf is stored on my computer at home. I haven't done this directly after upgrading because mine is a TMO-Xoom as well as yours. So there shouldn't be any differences instead of personal settings which are being wiped during upgrade preparation steps (rooting).

Until now none of the log entries really leads to an idea what happens there, will now wait for the next crash...
[Xoom Android Development] lowtraxx:
Okay,

then I'm puzzled as well. Lets hope the next crashlog gives us some more Info.
[Xoom Android Development] shmigao:
Thanks for giving me credit :-)

could you please tell me the process how you flashed this? as mentioned, i have been trying 2 days now and always wifi fails, as soon as I apply a Tiamat kernel (although I only tried with the Tiamat riptide 1.6GHZ version.

is this the right process:

1) flash boot image "Tiamat Xoom Kernel Boot Images For Honeycomb 3.1 ONLY"

e.g. "3G_Light_ON_Speed.zip"

2) flash kernel "Version 1.4.2 -- 1.5 Ghz Overclock for Honeycomb 3.1 Only NEW! with Overclocked GPU (other versions will have this soon)"

??

jeez at a loss here :(
[Xoom Android Development] lowtraxx:
Now I remember... Sorry, I'm an Idiot, I did only the second step, because the boot.img was already flashed once you installed HC3.1 (which already enabled SDcard in /sdcard/external and OTG). So I only flashed the kernel zip file and it worked from there. Could you please test if this is the same for you? I will then update the Guide accordingly.
[Xoom Android Development] shmigao:
:P

1 min. too late. already flashed the boot.img again and then the 1.5GHZ kernel.

let's see what it does :-)

rebooting

Edit 1: nope that didn't work... i think we are getting closer

--> restore to last HC3.1 position with working WIFI

now trying only the riptide 1.6GHZ kernel

Edit 2: nope, didn't work either... wonder whether they changed something. and slightly worried, because the 1.5GHZ kernel also says NEW after its description

--> restore to last HC3.1 position with working WIFI

Edit 3: simply flashing 1.5GHZ kernel over the 1.6GHZ didn't work either.

--> restore to last HC3.1 position with working WIFI

so now only one chance left....

Edit 4: OK, i give up... restored to the last HC3.1 state with Wifi work, ONLY flashed 1.5GHZ kernel, and Wifi not working again... restore to HC3.1 original state without overclock... what a waste of 2 days :/

i have no explanation for this, other than that the bcm4329.ko of the HC3.1 original state is slightly larger (~360 vs. 351kb), but when I attempt to push the original bcm...ko to the new system with Tiamat OC kernel, WIFI simply says "error"

:(
[Xoom Android Development] sandro.bertini:
Hi all,

I decided to give you all some additional detais about the process I followed, can be of help for other people:

1) My xoom was already rooted and had the recovery installed;

2) Followed lowtraxx instructions to the letter, with the following details:

2.1) Used ADB to pull the 4 files (settings and build.prop), worked perfectly;

2.2) Made my own build.prop, there was 1 different parameter (persist.ril.mux.noofchannels=9 in my device instead of 8, have no ideia what it is)

3) After rebooting, pushing the files and rebooting again, all was working.

4) Flashed Tiamat 1.4.2 with the verizon no-lights boot image

4.1) Using the recovery Install zip from SDCARD, installed the boot image (3G_Light_OFF_Speed);

4.2) Without rebotting, installed Tiamat 1.4.2, 1.6GHz, Riptide (Tiamat_Xoom-2.6.36.3-v1.4.2-2011-05-21_13-01)

UPDATE: Removed step 4.3 (other factory reset) cause it was hurting stability.

All works great, the only thing I noticed is that I don't get the H (HSDPA) icon anymore, it stays in 3G (the speeds seem normal though and the connection is very stable).

Tried to reinstall my apps with Titanium Backup but the market links did not work. Wiped and reinstalled.

Tried installing the 3.1 language pack v.05 but had major issues with my keyboard. Repeated the above procedure and now its fine.

If someone has information about the H -> 3G issue, please let me know.

Thanks again lowtraxx,
[Xoom Android Development] shmigao:
did almost exactly the same as you, but on my end WIFI no longer gets an IP address from the router :(
[Xoom Android Development] shmigao:
ehm... lowtraxxx

did you do a full wipe/factory reset after flashing the Tiamat Kernel, as sandro.bertini suggests in his thread?

....

EDIT, tried once more with full wipe/ factory reset after tiamat kernel, and it didnt' change a thing

i can connect to the router by static IP address, but the router apparently doesn't accept the DHCP ip address request from the Xoom in DHCP mode (before flashing Tiamat Kernel it did though...)

but even with static IP, it says I am connected, but i do not have internet access

any idea for a fix for that?
[Xoom Android Development] lowtraxx:
Hi,

no I did not wipe. I really have no Idea what else could break your WiFi.
[Xoom Android Development] shmigao:
yep, me neither. i am stuck with HC3.1 without tiamat kernel. wonder whether it could be obtained without any modifications to WIFI or 3G...

what i did notice is that once my Xoom is in that state, if it's longer than 10 min trying to obtain an IP address, it literally freezes up all routers. Throughout these 2 days I had to restart every router at least 20 times.

one learns through internet research that Android is not the best in DHCP/WIFI connectivity, but here at home at least my Nexus One, wife's Galaxy Tab and G1 are connecting just fine

frustrating

what is also frustrating is that the Tiamat Kernel and associated files have better 3G connectivity... at least it seems
[Xoom Android Development] mcfisch:
For those who have WiFi-issues: a well known problems on (modded) Android-devices is a timeout of the dhcpd. Since HC provides the ability to configure static IPs for each WLAN this could be a solution until this issue is researched more detailed (and hopefully fixed).

On the 2.x versions of Android this is really annoying because only 1 static IP can be configured statically. In HC this is much more comfortable...

Belonging to my own problem: I'll check my saved logcats tomorrow and post them. But before doing that I have to de-personalize them at first...;)
[Xoom Android Development] shmigao:
hi mcfish,

yes, on the one hand that is right. and I did succeed in connecting the Xoom (after tiamat kernel install) to the WIFI AP with static, but it did not gain Internet access, so this did not really solve my problem

I noticed 3 things:

1 - the bcm4329.ko of the tiamat kernels are smaller (in file-size) then the original HC3.1 bcm4329.ko

2. - bigrushdog in the tiamat kernel github mentions that he "attempted" to fix wifi errors with bcm4329.ko

3. - when i restore my backup with the last working WIFI version (which is essentially right after the HC3.1 upgrade) it initially also hangs in "obtaining IP address" (gave me a scare the first time...), but a restart of the DHCP router fixes this problem.... that means something in the DHCP router does not allow Xoom to (re-)gain IP address.... (unfortunately this method does not work after flashing Tiamat Kernel)

that some have this problem and some not also may have to do with different wifi configurations. on my end, as mentioned in one of my posts, after tiamat kernel flashing not only can the Xoom not obtain an IP address, it also crashes the entire router network (2 WIFI APs, 1 LAN switch, 1 LAN DSL router).
[Xoom Android Development] ed.dark:
I can confirm the lack of HSDPA icon. Speeds seem fine though. I had to bugger about with the APN settings to get it to show an internet connection (it had one but said it did not!!!)
[Xoom Android Development] shmigao:
how did you change the APN settings so that it shows an internet connection?
[Xoom Android Development] ed.dark:
I had to remove the port setting for talkmobile.co.uk. It shows an internet connection without it and no connection with it. A connection still exists in either case! Very odd.... I think we may have RIL issues with the Verizon ROM......
[Xoom Android Development] Marshall1975:
Ed.dark

I dont suppose you could post your build prop and 3 settings files as im on talkmobile but had already upgraded to 3.1 before this thread appeared so i was unable to get settings file from a stock uk 3g xoom

cheers
[Xoom Android Development] blackpenny15:
I can confirm an issue with talkmobile.co.uk I flashed my friends xoom for him and it doesn't seem to connect, just going to test in mine and get a voda data SIM in a moment.

UPDATE: also issues with my Vodafone, cannot connect like talkmobile, i've also noticed when adding a new APN with the following settings:

http://xdaforums.com/showthread.php?t=1051386

the APN will be deleted when going back, any ideas guys?
[Xoom Android Development] shmigao:
Final chapter on my tiamat kernel odyssey...

I flashed the other OC kernel branch (TDR /TRD?) at my office and wifi connected... elated I went back home hit wifi on and again, hanging on "obtaining IP address" now I believed I needed to update the DHCP router firmware, did that, but still the same issue

Now I believe the real culprit is my DHCP router (TP-Link.....) and I will change that one soon.

As I can connect now with static IP address, I flashed tiamat kernel... what a journey. Thanks for all your suggestions!
[Xoom Android Development] blackpenny15:
So its actually changing the MNC that causes the new APN to get deleted. I can confirm the talkmobile sim is working after removing the port and leaving all other details intact.

UPDATE: voda is now working, just apn:internet,un:web,pw:web was fine and enough to get a connection

TALKMOBILE: seems to be working even though it shows as not connected, apparently location services 3g is questionable...waiting for more details, anyone else?
[Xoom Android Development] Marshall1975:
Blackpenny

I have the exact same issue as you. On talkmobile with no connection then the APn's disappear. Reboot brings it back with no connection. I did have connection at one point but not anymore. Weird
[Xoom Android Development] blackpenny15:
did you remove the port?
[Xoom Android Development] rgribeiro:
What model is the 3G Euro XOOM? MZ605?

I'm from Brazil and here we have the MZ605 GSM model, and I'm wondering if I could update my XOOM following this guide.
[Xoom Android Development] Marshall1975:
Hello

Yeah I tried that. The no internet connection warning goes and its showing a signal but when you select market or browser it just gives a no connection warning.
[Xoom Android Development] lowtraxx:
rgribeiro: One member from Brazil already followed the Guide and reported that it worked here. Once I know on which XOOMs it works for sure I will update the Title.
[Xoom Android Development] sandro.bertini:
Hi rgribeiro,

If you look in page 9 you will find the procedure I followed for updating my VIVO Xoom (MZ605 as well) and it works perfectly.

Good luck,
[Xoom Android Development] mcfisch:
On my Xoom the APN disappears when the 3G-Connection has been gone. After the Network is available again (mostly after rebooting) the APN re-appears.

Anyway, here are the next logfiles, maybe someone can check it and gets an idea.
[Xoom Android Development] shmigao:
Can't look at the log at file right now.

One question, are you using paid apps enabler or similar to access US android market?

On my galaxy tab doing that makes the APN disappear as the phone simulates being in a different network, on my nexus one the apn changes to a US T-Mobile, on my xoom it stays with my native APN (funny how different the devices react...)

On another note, with or without port set in APN my xoom always tells me "no internet connection"

Finally, would anybody find it useful if I shared my Galaxy Tab build.prop? That is one device that perfectly works on 3G / HDSPA here, may be somebody can make a side by side comparison and find clues how to fix the xoom 3g build.prop
[Xoom Android Development] mcfisch:
I don't have any market enabler installed. I also disabled the Widgetsoid-feature for deactivating the data connection by renaming the APN.

Currently it runs without any problems since about 2 days....
[Xoom Android Development] lowtraxx:
I pushed /data/data/com.android.providers.telephony/databases/telephony.db and /data/data/com.android.providers.telephony/databases/telephony.db-journal from my Backup and now I have 3 more default APNs in my settings. I did this because I had the same experience as mcfish yesterday (3G suddenly gone), so I tried this and I have Internet still working till now. I will observe for 2 or 3 days and then update the Guide accordingly if this fixes that problem.
[Xoom Android Development] mcfisch:
On my Xoom the APN has been created as it should be, but I have another weird effect: If I let the tablet search for available 3G-networks, in the results every found network is shown twice. If I try to select one of the o2-networks from the list, only one of them is working, the other one shows an error...
[Xoom Android Development] lowtraxx:
I had the same issue too. With every network being there twice. But after copying the telephony.db the doubles were gone. And I had no network disconnect since then.
[Xoom Android Development] Marshall1975:
lowtraxx

Can you post a copy of the telephony.DB please. Also where exactly do I need to push it to. Lastly now I have data connection have you noticed no matter how good the reception is the xoom never shows more than 2 bars reception. Not a big deal but just wondering if its only me getting this.

Cheers
[Xoom Android Development] mcfisch:
For me it's the same. Only 2 bars and a poor reception compared to the stock 3.0.1
[Xoom Android Development] shmigao:
Same here (2 bars on indicator), but I do not notice poor or slower speeds.
[Xoom Android Development] Marshall1975:
hello

I have also noticed that after a few hours I love connection. All apns are gone and no operators are found. A simple reboot sorts this but its proper annoying. Lowtraxx any ideas mate.

Cheers
[Xoom Android Development] lowtraxx:
ATM I try to work out, why this happens and why the signal strength is locked to half. Could you please check the Signal Strength in the Settings -> About Tablet -> Status screen. I get 0 dBm 4 asu.
[Xoom Android Development] Marshall1975:
Lowtraxx

Had a look in settings and my signal strength is exactly the same as yours.
[Xoom Android Development] pepsi22:
What about your quadrant scores??

Now i got a 3.1 xoom with worging 3G , the language file 0.5 and Tiamat kernel 1.4.2 1,5 OC

But i just get an Quadtant score about 2700 !!!

What are your scores? Any idea how to get it faster?
[Xoom Android Development] shmigao:
Same signal strength here (exactly) and I am in China. Guess the meter is locked. I don't feel it slower than normal though
