Changing Wi-Fi MAC address issue

Well, maybe this will make you happy (although mostly likely not). There are others in the same boat. I have the same changing Wi-Fi MAC Address issue as well. I get a new Wi-Fi MAC whenever I turn off the tablet completely or whenever I simply turn off the Wi-Fi (via the slider switch or Airplane mode).

I have contacted Hisense on the issue twice since my Sero 7 Pro is brand new and running the latest Stock ROM from Hisense, P756.6.02.20.00. So, I don't believe the issue is related to the dopa ROM. It's affecting a few "lucky" Sero 7 Pro owners regardless of the ROM.

There's at least one other reported case over at Phandroid (androidforums) -- apologies but I don't have enough posts yet to link directly.

I have not tried doing a full device wipe yet. As I said, mine is brand new out of the box, but perhaps a wipe, cache delete from the service menu, etc. would fix. I'm not ready to try that yet (because I have mine all setup the way I want it, including registration with Adobe Digital Editions for eBooks and various Amazon services), but if I get time this weekend I may give a full reset/cache wipe/start from scratch a go since a constantly changing MAC is quite annoying.

I suspect that there are others with the issue, but they might not know they have it if they do not MAC filter on their routers (if you don't MAC filter, this is not an issue). I would also imagine/guess that the glut of refurbed units available recently on sites such as 1sale and Groupon might have been returned units that went back because users just could not connect to Wi-Fi, when in reality it was a changing MAC issue. Hisense probably turned them on, connected once to Wi-Fi, reset them to stock, and put them back on into the market for sale. Again, just guessing here... but there have been thousands of these things on the refurb sites. They are very nice tablets, so there must have been some reason for all the returns.
[Android Software Development] MrSimmonsSr:
It is good to know I'm not alone and also that it isn't related to something I did incorrectly when installing the ROM..

Thanks!
[Android Software Development] dolorespark:
Sorry for the delay in responding, [MENTION=1103144]MrSimmonsSr[/MENTION], but I got distracted - a stray male kitten decided to move into my apartment, to the great displeasure of my two stodgy old female cats. Anyway...

I completely wiped my system (after a backup), then reinstalled the stock 6.02.20 update. When done, my MAC address was the same as it had always been. This suggests that the address is being read from hardware (as is normally the case). On your tablets, this is probably failing so it's generating an address on-the-fly.

One thing you can try to help diagnose the problem (though we may not be able to fix it) is to pull a dmesg log, zip it then attach it to a posting. To do so, have the following already entered at a Windows command prompt, reboot, then run it as soon as the lock screen appears:

adb shell dmesg > dm.txt​

Note that this will only work (easily) with the DoPa ROM.

It could be the MAC address issue, but more likely, it's the shoddy construction of the USB port - there are lots of reports about that.
[Android Software Development] MrSimmonsSr:
Don't you be apologizing to me. I appreciate all you do, Sir!

Couldn't I run dmesg from a root shell just as easily? That is easier for me to do at the moment than finding a PC with ADB installed. Just wanted to make sure the output would be the same.

Thanks!
[Android Software Development] dolorespark:
That will work. You just want to get in there ASAP so we don't lose the beginning of the log - the buffer it's stored in isn't very big and will wrap around when it's full.
[Android Software Development] MrSimmonsSr:
Would it be best to reboot the device first, log on to wifi a time or two, then immediately grab the dmesg output?
[Android Software Development] revoke:
After a bit more research it might be only affecting Sero 7 Pro units that have MAC addresses starting with 00:34:9a: I see from [MENTION=1103144]MrSimmonsSr[/MENTION] post a few screens back that that is the range of his MAC address. That is the range of my MAC as well. So, I would wager this is confined to a particular hardware lot in that range, 00:34:9a....

I did come up with a workaround of sorts...

Here's what I tried to troubleshoot, and then finally came up with:

1) Full reset, cache wipe, data wipe. No change. WiFi MAC address still changes after power off.

2) Ran One click ABD, root, CWM (as outlined here: http://xdaforums.com/showpost.php?p=46196739&postcount=2 ). No change (and I would not expect one just by rooting)

3) Reflashed the full 330mb stock ROM update ("stock-v60220-full-update.zip") from here: http://xdaforums.com/showpost.php?p=46580445&postcount=67 in the hopes that the issue might be caused due to a corrupt or incomplete OTA ROM flash. Alas, no change. Wi-Fi MAC still changed after power cycle or tablet or WiFi. Note: I did keep CWM and root after the reflash of stock

4) Since my Sero was now rooted, I loaded up "MacMan" (available in the Play store) which can spoof a MAC address on rooted devices. It works fine with a rooted Sero 7 Pro. So now I can keep one MAC programed in my home router for the Sero and just use MacMan when I am at home to reprogram the tablet's MAC and connect. Still not optimal, but saves me having to go into my router every time the MAC changes. For travel (non-MAC filtered locations) this really isn't an issue, so I think I can live with things for now.

Thanks [MENTION=5094650]dolorespark[/MENTION] for the very clear root instructions in Post #2.

Posting volume for off-brand devices is driven largely by sales volume - and this is the slow season. Wait until the week before Christmas (gift givers) and the week after (gift recipients). Meanwhile, there's not a lot happening: randomblame's development of KitKat is paused, and there's only so much that anyone can do to mod a stock ROM. I was thinking of putting together a refresh of mine that includes my no-screenshot fix but I've been preoccupied developing my Phab7 UI switcher (vastly improved over the first release, innovative even). If Hisense releases anything, you can be sure posting volume will pick up in all 3 Sero7 threads.
[Android Software Development] jhienk:
Thanks dolorespark for the work you have done, really appreciate it. I'm not able to do the work you have done so much respect to you. I really love this device and anything that can further its developement i appreciate. Thanks again for your hard work.
[Android Software Development] someguyatx:
Yes thanks to all who have developed for this tablet. Hopefully Hisense will get smart and release an update and source before the holiday shopping rush begins. Would love to see more attention around here for this device.

I really like mine I picked it up new for 129 and ya its got some limitations at the moment but I'm running it stock with root for now till I see something that catches my eye, but I really like it its quick has wonderful response plays all games and apps that I have tried and use so far I don't see a reason to spend the high dollars just to have top of the line or something just because its a newer model.

I have the same problem with a sero 7 pro that I had bought

refurbished

. The MAC address keeps changing when the wifi or tablet is turned off then on. I didn't realize I had a problem till I decided to use MAC filtering on my home wifi. I now have turned off MAC filtering. Unfortunately, I need to clear my router every few weeks to clear the tables.

Here is the basic info of mine:

Production date sticker: 20130422

Model number M470BSA

Android version: 4.2.1

Kernel 3.1.10

Build number: P756.6.02.20.00

MAC address: 00:34:9a ...

My brother bought his

new and he also has the problem

. Same basic info as mine. Both of our tablets are running stock rom and were never rooted.

I hope this is not a hardware issue but just software problem due to the latest update.
[Android Software Development] MrSimmonsSr:
I have not figured out the issue yet, but I'm hopeful it is not a hardware problem because the issue cropped up after I had had the tablet a while.

Try using "MacMan" in Google Play if you need a work around until we figure it out. It has been a good tool for me, at least, in there mean time.
[Android Software Development] wing360:
I always thought the the MAC address was hardcoded into the chip/firmware code. I think the hisense uses a broadcom chip for wifi so hopefully its not a faulty chip and just a software issue.

Do you know if Hisense is aware of the problem and/or have you contacted them about it? If so, hopefully the next update will fix the problem. I'm closing in on the warranty period so I'm seriously debating wether to send my in for repair which is a hassle. My brother is still trying to find his receipt.

The tablet has been good so far. Fortunately, I don't use apps that use the MAC address for verifying identity authentication for use such as certain messaging and voip apps.

What changes from XE's ROM to this one?

What's been changed in this ROM from XBOXExpert's ROM? Does anyone know what was in the Hisense update?
[Android Software Development] dolorespark:
They didn't say, and I can't recall anyone identifying any problems that were solved. The update, which was a set of patches to the binaries, was pretty small.

I would think that the OP described it well enough, but to summarize: Hisense's latest updates, a slightly different set of additional apps, and a more ..umm.. sophisticated set of mods to the boot image. There's also a mod for this ROM (available separately) to remove the screenshot button.

Flashing the ROM

I've had my Sero 7 Pro for a couple of weeks and love it. I rooted it using the Kingo root app, but I notice that when I boot into recovery there's only "apply update from SD". There is nothing to flash a zip file.

I want to flash DoPa's ROM on Monday. Should I revert to stock and start from scratch?

BTW, I found the link to this thread after reading through about half of Xbox's original thread. :silly:
[Android Software Development] dolorespark:
The stock recovery will only work with updates from Hisense - you'll get a signature validation error using anyone else's zip. You'll have to install CWM to install anything else. The 2nd post in this thread has a package for setting up adb, rooting, and installing CWM. There are actually separate scripts for doing each task plus a "master" script that runs all 3. You can use the 2 you need or just let it do everything.

You needn't bother. The DoPa zip will simply upgrade you without deleting apps or data you've installed. If you want to start from scratch, install that ROM, then in CWM under "mounts and storage", select "format /data and /data/media".
[Android Software Development] CanuckinPA:
All Done!

Installed CWM, flashed the ROM and the 180dpi --- thank you thank you thank you. :good:

Might want to switch back from 180dpi -- everything looks a little small for my old eyes. The smaller widgets and icons look kind of odd in both landscape and portrait.

I'm going to have to play with the settings after getting home from work tonight, but how do I get back to the larger icons?

Thanks

DeloresPark,

Any chance we could get the sero7pro-sysui-phab7-v0.4.zip added to OP?

Thanks in advance!
[Android Software Development] gberpa:
AFIK, 230 dpi will give smaller letters, icons at a given grid size. Think of a line in a letter: it is x dots in length. If you have a higher number of dots per inch, your letter will be smaller. However if you programmed for 230 dpi, your resolution can be higher; eg more total dots in a given grid area.
[Android Software Development] Talon65442:
I'd tend to agree with that... except for the fact that changing the dpi from 213 to 180 does in fact make icons, text, buttons SMALLER :confused:

If anyone wants to read the explanation of what elgooG was thinking on that one...

[Android Software Development] dolorespark:
There's an update.zip in the OP for restoring 213dpi.

Better still, later today I expect to post a minor update to the no-screenshot SystemUI.apk and a vastly improved version of Phab7.apk.

Stuck at "RECOVERY"

Hi, I'm having a problem with the CWM step (I've rooted successfully):

I run script #3 and it seems to run fine. But when I try to boot into recovery, the tablet stops at the black screen with the green "RECOVERY" on it. I've left it for 20 minutes but it doesn't change, it's stuck. I've retried 5 or 6 times now, but get the same result each time. The tablet is otherwise fine and working normally.

I don't know if the following is useful information:

I could successfully boot into stock recovery before running the script.

Every file in /dev/block is zero bytes, even after the script (apparently) successfully inserts the contents of the .img file (6.7 MB) into it! Seems weird to me.... I've attached a screen shot at the bottom.

Before I ran the script I backed up mmcblk0p5. After the above problem i thought I'd check to see if I could restore stock recovery, and then noticed that my backup file is also zero bytes! So if course I can't restore stock recovery....

Have I done something wrong? There's nothing I can think of.
[Android Software Development] dolorespark:
The first thing to do is download the whole package again and replace all the files you have with new copies.

Next, try flashing Recovery a different way. Open a (Windows, I assume) command prompt and change to the directory containing the unzipped files. First, run

adb reboot bootloader

then, after "Fastboot" appears, run

fastboot flash recovery cwm_touch_recovery.img

At this point you can either run "fastboot reboot" followed by "adb reboot recovery", or you can force the tablet off and boot into recovery using Power+Volume down.

I get the same output if I run "ls -s". Instead, use "ls -la".

SystemUI / Phab7 Update Available

I've posted a new version of this package (sero7pro-sysui-phab7-v0.9.zip) which removes the screenshot button from the Navbar and adds Phab7 v0.9, an on-the-fly UI switcher. The SystemUI update is just minor change from the previous version while the new Phab7 v0.9 is a vast improvement over the original release. See post number 3 on the first page of this thread for details.
[Android Software Development] DesDr0id:
I picked up the Sero 7 Pro for the same reasons -- Great Price, a Nexus 7 + all the things missing like HDMI out, SD Card, etc.

Unfortunately that's where it stops. There is a serious lack of support from Hisense -- I've emailed them several times for different reasons and no response at all. They have not released the kernel source (which would do wonders for development) and they have yet to keep on their promise of delivering a 4.3 update. HDMI out is buggy. Time will tell if they can get their act together....
[Android Software Development] gberpa:
I briefly ran the new ROM with Phab 7 0.9 and have Gravitybox 2.7.2 with no issues and it was linked to the micro SD card with Link2SD. Not sure but believe it was not "frozen".

Now I am on the prior ROM with Phab 7 0.4 with also no issues with Gravitybox linked to the card. It definitely is linked and not 'frozen'. It may be other settings causing your issues.

The reason I reverted to the earlier ROM was I lost my custom wallpaper whose file is on the pc and my ES Explorer is (I hope temporarily) unable to access my LAN via either of my tablets. The wallpaper was imbedded in my prior CWM backup so it came back. Unfortuately, I lost it again going to 213 dpi.

Not sure if it is my settings or what, but the prior ROM seems to run a bit smoother, zippier. Anyone else note this?
[Android Software Development] jonalowe:
I've noticed that I need to hook up the HDMI to the Sero 7 first and then the TV, but it works fine with my Vizio flat screen. If I don't do it in that order, I don't get a picture. Haven't noticed any other issues.

Yeah, source would be nice, but it does what I want, which is more than my Nexus.

What are you looking for 4.3 to do for you?

[Android Software Development] CanuckinPA:
I installed Link2SD, but when I try to move apps to the SD card I get a toast that says

App2SD is not supported by your device. Because your device has a primary external storage which is emulated from the internal storage.

You can link the app in order to move its files to your SD card
[Android Software Development] gberpa:
You need to link, not move. That works on many apps and on much but not all data. See the Link2SD developer thread.
[Android Software Development] CanuckinPA:
OK - when I try to create a link I get a toast that says

Not Mounted

I have a brand new blank 16gb micro-SD card that shows up in the file manager. :confused:
[Android Software Development] jonalowe:
Read the instructions for the app. You have to add a partition to the SD card. I added an ext2 partition. I did it with an app on my computer, but CWM ought to be able to do it. Both your FAT partition and the ext2 have to be active partitions, not virtual.

EDIT: I used "MiniTool Partition Wizard Home Edition 8.1.1" to partition the SD card on my PC. The instructions for Link2SD are in the description in Playstore.

[Android Software Development] CanuckinPA:
Thanks Jon. I used MiniTool - partioned the SD card by following this tutorial -- and then apparently successfully linked 28 apps to the SD card. *the app said the linking was successful

I say "apparently" because when I look at the SD card using ES File Explorer there's nothing in either partition. :(
[Android Software Development] jonalowe:
Yeah, nothing shows in my ext2 partition either, but all the apps work. Have you put anything on your FAT partition?

I recently got my Sero 7 and after playing with for a few days I tried to root it and install CWM recovery using step0-DoItAll. It seems to be rooted OK but when I hold down power and volume up I go to a fastboot screen and it never goes to CWM recovery. I can hold down power and volume up and power off and then power on normally and everything works fine. When I first ran SuperSU I got a screen with some options and I wasn't sure what to do so I selected go back. I don't remember all the choices but I think one was stock developer. How can I fix it?

Thanks for the reply dolorespark. I downloaded the files again, and flashed using fastboot as per your instructions, but the result is the same - I can't get into recovery, it just stops at the green on black "RECOVERY". (I use Linux btw)

I have the 8 GB model, model number M470BSS, build number P756.6.01.10.AU00

Could there be any problem there?
[Android Software Development] 111cab:
Found my problem

I tried this and when I enter "fastboot reboot" the tablet reboots and loads normally. I never get to enter "adb reboot recovery". When I hold down the power and volume up button I still go to the fastboot screen and stay there. Am I missing something or am I doing something wrong?

UPDATE

I just tried booting recovery with power and volume down instead of power and volume up and I booted into recovery. Thanks for the help and sorry for being so dumb.
[Android Software Development] Dre363:

They've ignored my requests regarding the 4.3 update and the kernel source. They did reply to my support request regarding the HDMI issues, but only to tell me it was a problem with my TV.

Hello everyone!

I have an AT&T HTC One that is S-Off, relocked, SuperCID, black HBoot 1.54, currently on ViperOne 2.7 with stock kernel. I've been trying for the past day and a half to get the 3.22.1540.1 Brightstar WWE to run so I could have it back to stock with the most current OS. I also want to fully convert it to a Developer's Edition phone as well. I thought that with SuperCID you could run any RUU but so far every single time it ends in an error. I also tried changing the CID to the Developer's Edition CID (BS_US001) and still came back with the same error. So here I am on the greatest place in the world for Android phone assistance and advice asking for help in getting my phone converted to a Developer's Edition and/or on the 3.22 RUU. Thanks in advance for any help.
