Ever since I got ARHD on latest .24 its been running super fast with minimal problems. One problem I am having is the internet disconnecting randomly and having to turn wifi on and off for reconnect. Also when it is connected it is incredibly slow and other devices on my network are having no problems. How do I fix?
Also I updated to the latest ARHD last night and having more problems than ever so that did not fix.
Try latest guevor kernel, it will fix it.
And do I just flash it after flashing ROM?
Flash the ROM, let it reboot normally, then go back into CWM wipe cache and flash Guevor's. It changes wifi protocol to Veno from Reno whitch helps alot.
I'm still having problems with wifi. Speedtest app is saying I'm getting like 5mbps down yet webpages are taking up to 15 seconds to load and when I look at the wifi bar on the bottom the arrows that indicate data usage sometimes just disappear and the page stops loading for 10 seconds. Same thing for youtube videos. It is taking forever to buffer even on non HD quality. All the other devices on my network are having no issues and everything loads snappily.
Kernel maybe?
You may be having problems with an incompatible kernel[if you did flash an alternate one] or it may just be a bad flash.
Either way, try re-flashing the ROM
The thing is ive had the same problem on other roms and I have tried reflashing.
Edit: I am using the test series of kernels and its the one that is compatible with Megatron. Any other ROM suggestions? The stock Megatron one?
Did you clean or dirty flash? You need to wipe Everything..
I wiped everything
Try using the superwipe script from the ARHD thread, then flash Guevor version 17c on a Non-AOSP Rom (Revolver or ARHD) See if that'll do it.
And if I titanium backed up all apps and data is that good enough? Also if I do a backup in cwm can I restore to my same state I'm in?
Also if I run super wipe script will I not have to wipe caches and stuff?
Yes you can, personally I'd just backup the apks.
Wipe caches anyway never can be too safe.
And the wifi is still not fixed
Guevor 17c?
Yup
When I click on a link you wait a while until anything happens and any data is exchanged. And my sd still won't mount in CWM
Your issues are starting to sound hardware related... :/
I already RMA'd this thing once because it did a never awakening SOD before I was rooted. I'm trying to figure out how to flash stock ROM/kernel to see if problems persist while keeping root.
They may or may not X.x It all depends on which demons are currently inhabiting your TF.
Try the latest Harmony kernel, that might fix wifi.
Thanks for all the help greatly appreciated.
I did some "scientific research". I loaded squarespace.com on my tablet and it took 27 seconds. Loaded same page on laptop and it took 5 seconds. I waited for it to be fully loaded. If I do speedtest.net on my tablet I get the same speeds as on my computer but the only difference is a huge lag time before any loading happens and then while its loading it pauses multiple times. If I have had this on every single kernel/ROM combo I have tried is it safe to call this hardware?

Hello!
So there is this annoying thing that's been going on since I firstly rooted my phone and started flashing ROM's, radios etc.
I've been using only ARHD ROM's since they have a great reputation, haven't tried others.
So, I started with ARHD 3.6.x ROM's and now I'm on the latest 6.2.1. XE ( No OC ).
So the problem for me all through my experience with my phone, is getting random reboots at mostly no specific times.
The most common is in this situation:
The phone is just sitting nicely in my pocket, I feel that somebody is calling me. I take the phone out of the pocket, want to answer by unlcoking the phone and ding! it just crashes.
When I turn it on, the random reboots just won't stop until I give the phone a rest and don't use it for a while. Because after a random reboot the reboots just keep on coming, if I use the phone.
This also happens when I just take the phone out of my picket and try to unlock it.
So, mostly it reboots when I try to unlock it.
This just makes the phone unreliable and many times people can't call me because I have no idea that it has crashed in my pocket.
I've been hoping that it would stop with the next version of ARHD but it didn't. The problem keeps comming back.
So I wanted to know: Is there any way to see, what is the soul purpose of those crashes? Is there anyway it's curable? Because I don't know if it's the HW or the SW. When I had stock everything and no root, these problems were not present.
My setup:
* Super CID
* Firmware from 3.24.401.1 & 3.25.401.101 RUU
* Android Revolution HD 6.2.1 XE
* Radio: 11.68.3504.00U_11.21.3504.13_2
* Kernel ( from about info ): 3.0.16-g5e58c5e [email protected] #1
* Any other info you need to help me fully?
the kernel could be the problem...try not to use it and see if it happens again..however i suggest to you to flash the insertcoin rom cause it is the best ics rom out there...trust me try it and you will not be disappointed
I have the same problem with all ROMs, including stock, except for the Virtuous Quattro alphas which I was able to run 20 days straight without a crash (impossible with other ROMs). Also the battery readings after a crash is weird, dropping from eg. 60% before the crash, down to 5% when booting after a crash. I contacted HTC about this and they told me it's probably a faulty mainboard. So I'm planning on sending it back in a few months.
I have the same problem with all sense roms GB and ICS its really frustrating I've had it for some time already

Today I will try virtuous_quattro_alpha3_pyramid. If it's too buggy, will try the Inqusition. And if I still have any problem, give the InsertCoin a try. Will post my findigs as I get them.
Any idea what kernel to use? Which is the most stable?
not sure but crashes may have something to do with your applications being in sdcard. i have moved all my applications to phone memory (though i don't have many) and i have not had a forced reboot after that. also super-smooth/ultra-smooth rosie helped, with this tweak my phone is really fast now.
using leedroid rom.
If the phone didn't reboot on stock then it's a firmware/software issue - go back to fully stock and see if the problem still occurs.
If not then start from scratch and make sure the checksums match the downloaded file before you install then, especially the firmware and radio file.
From my hd2 days you might first try setting your network manually, as I did hear that even native Android phones can reset during auto network selection.
So now I am on Virtuos Inqusition and the reboots still occur. It's frustrating.
And ONLY when I take my phone out of my pocket to see what time is it.
So I met a guy who is on all stock, without root etc. and he's getting the same issues.
Anyone else having this problem?
Could it really be the HW fault?
Or still could just be because an official ICS ROM for the Sensation hasn't come out yet?
Full wiped?
Did you full wiped it before you upgraded to the latest verison? In many cases reason for reboots are kernel and/or cache related. So maybe something which is still in your cache could bring that output. Another possibility is when you restore apps and settings from System Tuner or Titanium backup. As you are using stock kernel I don't think it should be the problem generator.
1. Do a nandroid backup
2. Full wipe with Mike's script
3. Fresh install ICS rom you like (I'm using Insertcoin 4.5.4 + Ultrasmooth Rosie)
4. Check MD5
5. install custom ROM
6. Don't restore settings/apps from Google.
7. Don't restore apps/settings from Titanium etc...
Just try to use your phone without all your apps installed for a short time.
Good Luck, hope it helps...
Yes, I always Super-Wipe before a fresh install.
But I will re do everything, installing only the timetable for buses - addicted to that app.
Can I restore contacts from google or should that wait for a while?
Update
So, it's been a while that I've been using Virtous Inqusition with Google sync and nothing else. The original problem still exists, Could this be a HW issue?
I don't really want to go all stock to loose SuperCID and everything else.
So, I guess I have to stick with this problem and leave my Sensation unreliable.

Do a full wipe and reflash the ROM also wipe the battery stats and perhaps try a different kernel maybe one closer to stock frequency

I have tried all of the ICS roms, and always gets stuck at the same spot. Wi-fi is turning on.
It worked on the Revolver 4, but I wanted to try another one. Did a super wipe, and bam. Nothing after that..
Any thing I might be able to try?
Nandroid restore, if that won't work nvflash?
you mean use NVflash to do the rom install vs the recovery?
I made a topic about this, check my post (not able to give you a link right now sorry)
I also need help with this. I am trying to come from CM9 cornerstone build back to revolver. I have done a couple restores and I still get no WIFI. Anybody have anymore info on this?
Have a look at this : http://forum.xda-developers.com/showthread.php?t=1530612
You can try this:
- Turn off wifi
- rename the file /data/misc/wifi/wpa_supplicant.conf to wpa_supplicant.old
- reboot
- try wifi again to see if it works
**note
This might cause the tablet to forget any previously saved networks.
I have tried Outpoxs' method in varies combinations with no success also I have tired your method a.mcdear and also with no success. Mine is still stuck on Turing WI-Fi on... The one thing with outpox method there might have been something I was doing wrong.
This is how I fixed my tablet after 15 hours of trying everything. I downloaded the ota rooted full version of ics and performed a full wipe then made sure it booted into that rom with wifi working then proceeded to flash my revolver backup with no problems. Hope that helps.
Similar WiFi issue - still stuck
I hate to bump an old thread, but I've recently hit what appears to be a related issue (WiFi stuck off), though perhaps there are some twists to my tale - and I'm still stuck.
I have an early TF101 (B50) and have had it rooted with stock ICS for awhile. Everything has been mostly fine, but I decided to give CM9 nightlies a try.
Here's where my issue differs from the others in this thread. With the CM9 nightly flashed, I was stuck at the boot animation (for hours - left it overnight with no progress). I restored my nandroid backup and now I had the "WiFi Turning on" issue that others here have experienced.
I've tried multiple other ROMS (latest of AOKP, Gummy, and Prime 1.6), with complete wipes, and in each case, I was stuck on the respective boot animation. This completely mystifies me, but it may not be related to the WiFi problem. After each iteration of failed ROM flashing, I can restore my nandroid backup (the rooted stock ICS) and everything works fine EXCEPT WiFi.
Following the suggestions in this thread I've tried flashing a new stock ROM (from http://forum.xda-developers.com/showthread.php?t=1514658) and while that doesn't stick at the boot animation, it also doesn't fix my WiFi. I also tried a.mcdear's suggestion in http://forum.xda-developers.com/showpost.php?p=23446585&postcount=7, but I did not have the file wpa_supplicant.conf in my /data/misc/wifi directory. The only file in there was an empty file called "status." Just for good measure, I tried renaming it, but no joy.
At this point, I'm out of ideas and have a severly crippled TF. I would appreciate any suggestions or ideas from the community.
TIA

I've have a rooted TF101 B50 and most ROM's that I have tried seem to fail at this point as well. However, I did notice that when I flashed my first ROM (AOKP) it has the same stock kernel. So I tried another one. This time was Revolution 4. It seemed to work out just fine because I belive it has the stock kernel. Next I moved onto a CM10 Eruoskank ROM. It too had the problem of the AOKP ROM in that after I flashed it, the stock kernel was still present, presumably left over from the Revolution 4 ROM. I am now on Android Revolution HD 3.5.0 and it seems to work fine so I am sticking with it for the time being.
I beleive something in the flashing script of the ROM or the recovery program itself is not flashing the /boot partition properly. I am not a developer nor do I have an in depth knowledge of the inner workings of Android...but this is just a guess. I hope there is a way to flash just a kernel in the /boot partition from these individual ROMs. That would be nice.
If can access recovery then do a full wipe(system, cache and dalvik) and install the ROM again... that should do the trick... you might wanna try some other kernel also... there few kernels for ICS in the forum look for them and flash them via recovery...

rstry this:
take unit out of dock if you use one. restore via cwm if u can, to 3.01 firmware, honeycomb. wipe all cache, data, etc prior to flash.
DO NOT SIGN INTO GOOGLE ACCOUNT.
Turn tablet completely off following boot. Cold boot back on. Grab latest official firmware off Asus website, xx.27
Install via CWM, and again wipe ALL.
Boot into system again, and cold boot back on. Asus should prompt you with 300mB update now, which differs from the official .27,but had same filename...
I found this bug/glitch a few hours ago... Somehow downgrading to HC and back to stock triggers this unknown update...
See if you can reproduce please. I also saved the firmwares to sdcard external.
The various ROMs require a supporting kernel. I would try obtaining the correct kernel for the ROM you want and then flash them both at the same time from recovery.
Resolved - for me
From replies here and other research, it became clear to me that I should reflash my transformer back to stock (NVFLASH down to the metal). Every other ROM would show the stuck WiFi issue or (worse) would get into a boot loop.
This was something of a problem, because my volume up button was broken and I couldn't enter APX mode. I finally managed a workaround for that (see http://forum.xda-developers.com/showthread.php?t=1890236) and then used EasyFlasher to restore the Asus firmware. Now the WiFi works fine and all is well again.
So, as a last resort - scrub and start over.
Cheers!

I also have the same issue. Bought the eee pad transformer with a cracked screen; touch screen did not work. I replaced it and everything works great! except for Wi-Fi =\ Any help would be greatly appreciated!
You should really start your own thread. That being said, first thing to try is to back up all your data and wipe it to factory using EasyFlasher. If the problem persists after a stock firmware flash, then it's likely a hardware issue. If it's resolved, then it was a rom/software issue.

Im 99% sure your problem is that you haven't got the right kernel for the rom your using, this is the usual outcome - wifi not working/ turning on. i don't think nandroid backs up the kernel so your basically restoring stock ICS rom with cm9s kernel. Try find the related kernel to rom your currently on. As for your rom failed flashing, you might be using a very old recovery try updating to the newest twrp recovery. Better yet join the dark side and move up to Jelly Bean, makes the tf101 a whole new device.
Hi! Yesterday I've decided to flash custom ROM with sense 4.0. Downgraded HBOOT to 0.98.0000, then performed S-OFF via Revolutionary, then ROOT, FULL WIPE and installed Fallout v.4.4.0, stock kernel 3.0.16. Device reboots itself very often when trying to use it, for example, it reboots while downloading apps in market. Also a problem is that switchers of WiFi and Mobile data are often become unavaliable when I try to switch it ON or OFF, only restart can help.
Also I tried this kernel http://forum.xda-developers.com/showthread.php?p=30507159
Device with it seems to be much faster and smoother, but it's not the way to fix reboots and data transfer togglers issues.
After all of this I installed one more ROM - Nik Project X, but the same problems annoying me!
I can't find reports about such problems on forume. Seems like there is problem with device, but I had never such reboots on stock Android 2.3.5.
Can anyone help me? Should I flash another radio, maybe, or what?
solved
Flashing new radio solved all my problems!
I would have posted this in the Sensation Android development area, but I don't have sufficient privileges to do so.
I no longer have WiFi.
I am using the 4.1.2 CM Kang, and I originally had WiFi working with that ROM, but it stopped working about a weeks ago, and I can't get it to come back.
If I watch the Wifi on/off toggle, I can see it blink white for a split second then return to grayed out about once every 5-10 seconds.
I've checked the WiFi settings, and the only thing that looks peculiar is that the region code under Advanced says "Europe," but when I try to change that, it just reverts.
I have tried a factory data reset,re-flash of the ROM, and installing newer versions of the ROM with no luck.
Does anyone have any suggestions?

I tried to install WiFix Manager, and I followed the directions closely, but WiFi still will not turn on.
The country code always reverts back to Europe in the Advanced WiFi Settings.
I'm on T-Mobile US, running AOKP aokp_pyramid_unofficial_Oct-19-12.zip; a JB ROM; 4.1.2
I previously tried the CM10 Kang for the HTC Sensation, but switched ROMs to make sure that it wasn't issue with the ROM.
To be clear, my problem is not that the WiFi radio never locks to a particular signal, it's that the WiFi radio won't even turn on.
When I go to WiFi settings it just says, "Turning on WiFi...," and never actually turns on.
My best guess was that it had something to do with the WiFi country code, but that's really just a stab in the dark; open to suggestions.
Thanks

In order of easiest and quickest to longest time it will take to do each one...
Install the latest version of the ROM (10/23) overtop of your existing rom (5 minutes)
If that doesn't work...
Do a full wipe and install a fresh copy of the latest version. (15 minutes, with Nandroid backup)
If that doesn't work...
Format your SD card (save all the contents to your computer first) (40 minutes between copying every to the computer and back to the SD card)
NON ROM RELATED OPTION IF YOU ARE S-OFF
Reinstall your firmware as it's possible something got messed up. You will have to boot to recovery after this and wipe cache and dalvik or you will get bootloops. (5 minutes, but a little more involved)
My guess is that the full wipe and fresh install is the most likely to work the first time.

is there a sensation specific guide for this procedure?
Still perplexed
How do I know which kernel and radio combination should work best with my ROM. I switched out to AOKP to see if that was the problem, and I believe I'm using the 3.33 Kernel, but I don't know how to check to make sure it installed correctly.
Had the same problem as you but a full wipe and reflash would bring it back. Seems to be a CM10 problem since it happens with Bruce's and Paranoid roms. Try a Sense rom and see if wifi works.
Is OpenSense considered a "Sense ROM?"
http://forum.xda-developers.com/showthread.php?t=1926858
Try that rom, more stable and better performance than all the popular roms.
I had the same problem only option was another room Android_Revolution_HD-Sensation_6.8.0 (this is the rom)
so long, and thanks for all of the fish...
I figured it out.
I bought a Samsung Galaxy S III. WiFi is working again.
Thanks for all of the help!
wifi cm10
I have tried several CM10 roms. It is as you said about the region code. It reverts back to the original and doesnt save it on the settings
Even though editing db file doesn't work. Actually it changes the country code. I guess the ROM changes it during booting. Because while it boots you can see that the wifi is connecting first then goes off. I have tried several roms. DOnno what the problem is. probably JB both on cm10 and aokp
Motorola XOOM Z604 32GB IHDT56MT1
Sorry if there was another thread about this, but i looked and didn't find any
Anyway friend of mine flashed some kinda rom he says official 4.1.1 JRO03H, but i'm not sure
anyway as he said after OTA tab is freezing randomly and gives android keyboard error
so i assumed i can unlock/root and flash some custom rom that will resolve the problem
after using AIO tool and unlocking/rooting/flashing various roms problems persists
sometimes tab is crashing during start up (android loading) sometimes just randomly by touching/using absolutely random
using tiamat recovery 3.2.2 and TWRP, it's rock stable in recovery
so i assume it's hardware related
any ideas, cause i'm out of any
p.s. it does have a sim card slot, but judging by FCC code it's wifi only
p.s. i tried to flash stock rom and lock it, still freezing and crashing randomly, first at wifi menu then at internet browser, guess something is really hardware related, possibly memory got corrupted or something like that
p.p.s now i'm not even sure which xoom this one is, is it a wifi only or 3g and maybe it needs some different stock rom? most confusing tab i've seen so far, there is just so many variation of this
thnx in advance

The wifi xoom also has a sim card slot but it does not work( missing the radios).
Can you get into recovery and which one is it (custom CWR or stock)? With the xoom off press power until the moto dual core logo appears then press volume down after 3 seconds. You will see android recovery written on top press volume up. If you still have a custom recovery you can then install 4.1.1 JRO03H again but do a factory wipe (very important to get rid of any possible corruption) before and a cache dalvik cache wipe before.
If you are still having issues you can fastboot the stock honeycomb wifi images and allow the updates to happen automatically but this will wipe all of your data. I can walk you through this.
i did mentioned recovery in my post, otherwise how the hek would i be able to flash it in the first place duhh
i did all that, i even tried stock image 3.01 let it update it all the way up to the 4.1.1 which kept giving me weird android keyboard stopped working error and same random freezes
most stable was honeycomb though, i could stay in the system sometimes longer before touching anything, i even let it on lock screen for an hour or two and wouldn't freeze, in ics and jb it froze on lock screen, sometimes wouldn't even let me pass welcome/choose language
i just don't understand how can it install without any problems and stock/custom recoveries being stable while in OS it's just freezing for no apparent reason, my theory is something wrong with video part of the chipset, then again i simply dunno anymore
i tried several times factory defaults and wiping cache before and after flashing didn't helped
Good luck
