Last_kmsg: IOMMU DebugFS Support Enabled - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hello everyone,
Long time mystified lurker, first time poster.. before you jump my arse please know that I have searched the forums to the best of my abilities. I am only able to find answers regarding custom kernels/unrelated posts. I have an unrooted completely stock out of the box ATT carrier locked S20 Ultra 5g (SM-G988U) with the Snapdragon 865. Please forgive me because I am learning and doing my best to provide relevant information. But within my recovery logs for last_kmsg I get a big NOTICE stating tace_printk() is allocating extra memory and that IOMMU DebugFS has been enabled. I cannot seem to figure out why this notice is appearing and I cannot get any explanation from ATT or Samsung. I recent called ATT via 611, after being connected to a manager and laying out my question, I was hung up on and my sim card was no longer recognized. I tried putting my sim into a carrier unlocked moto g7 play and it also does not think I have inserted the sim. I had to go into the ATT store to purchase a new simcard and the new one works perfectly. My data was never turned off in my account and my sim card was supposedly still active according to the store employee.
Again guys, so sorry for the dummy talk... thanks for sticking with me so far!
This may or may not sound stupid but it appears I may have a virtual machine running on top of my android system?? I ran a GPU Benchmark and my GPU Load never increased from 0% and my CPU seemed to have been doing all the work.
I cannot get answers from XDA forum searches,, Googling, ATT, Samsung, employer and I am genuinely concerned because I work for a financial institution and at one point had my work email configured on this device. I handle lots of PII so I have been taking unpaid vacation to try to figure this out without much luck.
I have not and could not possibly cover everything I have tested/searched/noticed. I am basically either a lot dumber than the average bear or my internet searches are being filtered to make this troubleshooting extremely difficult. At this point I am going out of my comfort zone to post online for the first time ever on any forum so please be gentle with me. Also, I could literally talk for days about what I've done and what I have figured out these past couple weeks so PLEASE ask me questions if you have any. You can mock me and call me stupid, please just do so in a manner that details where I am going wrong.
Sorry for the crappy sentence structure and grammar... I was a sailor and not a college student for a reason! Thanks for any support you can provide!
Much love

so you went looking into device kmsg logs and found something u dont understamd and assume thats what killed ur sim card?
lol
thats normal output on many samsung devices.. its not anything nefarious.. not sure what u mean about a virtual machine running lol.. i suppose if u installed and set one up maybe ones running?
either way it sounds like ur device is fine/normal and ur just looking into stuff u dont quite understand.. and i can guarantee att or sammy reps etc know less than most ppl lol
that being said, sim cards can fail sometimes and need to b replaced.. ive had a few die randomly over the years.. it happens. It also indicates bad sim seeing as how it didnt work in ur other device eithet.

I have noticed this same thing. The warning message obviously states that it is unsafe for production use therefore how is this supposed to be normal? I am just as concerned with this warning message as you are. I hope someone that knows something more about it will come forward and provide an answer that actually offers some kind of real explanation as to what is going on here.

Bad NAND blocks causing problems?

I've installed and reinstalled android since the .7 builds before android 1.0 was out, i've installed using data images and ext2 partitions... I've put my time in, so i've had a G1 since december and have pretty muched stopped playing with my kaiser, I picked it up today and have been trying to do a NAND install of Poly's build with no luck... got the 320x240-Panel2-Tilt NBH installed and booting, along with poly's build dropping into the andboot folder... and updated to radio 1.71*, after doing a install to NAND (and wiping /data & /system)... I see that I have bad blocks on my mtdblock3 (NAND) when its mounted... I cant seem to boot android all the way, anyone else have a bootable android that has bad blocks... AFAIK most devices that use NAND work around potential bad blocks (Wii, XB360, etc) will it format around these blocks?
wow, I reflashed the .NBH, and still getting the same bad block error, set the phone down and was browsing the web and listening to TwiG, look back over at the phone and it WAS sitting on a shell on a blank line ie. "#", and started the NexusOne logo!!! so I guess its all good with bad blocks and all!
Now another question, I'm on a $9.99 featurephone unlimited dataplan for AT&T, if I throw my sim back in my Tilt, will they figure it out? I dont have my IMEI registered, but obviously they can see it... lol, I know its a little off topic.
I have 3 bad blocks on my Tilt and doesn't seem to be affecting anything.
Yes bad blocks are a part of every NAND memory device. I read somewhere that there is like a 5% failure rate on these types of memory. It's just how the tech is. However, there is a system built into it to keep track of the bad blocks, once it's marked bad, it will never be used. I also have 1 bad block and have had no ill effect on my kaiser. It just seems that the boot process lists which blocks are being reported as bad by the memory.
Hope this helps.
I have around 7 bad blocks, and OK with my sistem.hahahahahahaha.

Yeah they will. They figured it out in less than a week when I got my old Hermes. Even without my IMEI registered, and a custom ROM installed, my account on the site showed I was using a Cingular 8525. They automatically switched me to the $30 data plan. There was absolutely nothing I could do.
at&t
"They" do know, but if you have a feature called "smartphone exclusion" you can get away with a $15 data plan, but as soon as you upgrade to a smartphone the exclusion feature is removed.
So, if you have two lines always upgrade the one that will not be using a smartphone, then switch sim cards.
The only way to know if there is a smartphone exclusion feature is for a rep to open your account and look at your feature codes, even the $0 features.
This probably doesn't make any sense, but I wish there was a way to block an IMEI, then no problem. In the past we could put all 1111's for an imei in the system as a non att phone and there were no reprocussions.
peace
I've wondered the same thing at times about the imei. It seems every time I went exploring the "making imei different' option, all I would ever get is the big lecture about stealing phones.
(RANT ALERT)
Kinda like when you go buy allergy medicine and get carded, cause there are a bunch of losers out there doing something illegal with it.
I am not sure of the ethical issues with using 'too much data' or paying more, b/c I use my wife's Samsung Flite (insured non-smartphone) with $15.00 internet tethered bluetooth to my laptop, so eh...... I'm always a stickler for paying what I think something is worth to me, especially after a company has REALLY taken advantage of me a time or two. And btw, where I live, I only get 1 bar most of the time. Really, our phones hardly work, so we have skype on the PC to make calls from our home. They work great in the city that I work in, but i'm on a computer using google talk mostly. Can you say "Holes in the coverage map?" And yes, i've tried all the radios. Be it my kaiser, the old hermes, my wife's samsung flight, or the 3 we've had Blackjacks, theres just never been good coverage. So ya, I think i'm overpaying a bit. I just use my phone as a toy, a hobby, a see what it can do.
I've read about IMEI changing being illegal in certain countries. What about the USA? I mean seriously, I drive a car with no catalytic converter, but we don't have emissions checks in my state. Yes that means I'm breaking the law, but I also think that relatively speaking, i'd rather the police spend their time busting Meth labs than worrying about my car emitting 20% more stuff from the exhaust.
Its all about saving money, because everyone is trying to get ALL of it from you.
(/RANT)
Can the imei on the kaiser be changed, or killed for that matter? Has it been explored?
And please, spare me the stolen phone lecture. I just don't think I can take it.

Pulling out the catalytic converter won't increase your mpg, as many modern cars actually require the back pressure. You'd have to also modify the computer, or own a car made in the 70's and older.

I bought my Kaiser off Ebay, and it's actually made for the UK. Just to try and avoid having to pay a $25 fee for having access to unlimited internet. Course the 3G doesn't work with T-Mobile in USA, but I use 2G anyway to save battery power.
Cell phone industry is just one big scam. You can't afford to buy a new phone, unless it's under contract, and switching cell phone companies will cost you a disconnection fee. Not to forget that their cell phones are locked to them only, and requires you to beg for the unlock code.
Honestly wish that T-Mobile had a $10 fee for getting unlimited internet, cause relying on wifi is a huge hassle.

Well i've officially derailed this thread. sorry. I'll go join the ranks of losers that I always complain about
BTW, my car doesn't have a cat cause its a 18 year old Cutlass Calais, and I'm not paying to put one back on where the original one rusted away. It does have a new exhaust however, and right where that cat converter goes is a nice shiny honda resonator from a civic Si (got it from a friend at college when he put an aftermarket exhaust on his car).
I don't think you'll get prison time in the United States for messing with your phone, I'm not sure either. I've never heard of it actually happening due to someone changing imei numbers in order to profit criminally in some way.
BTW, just to tie this thread back into its original form, i've gotten Bad Nand blocks reported one time. I flashed hardspl again using sdcard method, and haven't seen them mentioned in android boot since. Weird huh?

I get errors with bad nand blocks as well, but as someone mentioned, that's normal. It's like buying a LCD TV and you see a few dead pixels. That's normal, even though it pisses you off, knowing that companies dare make products with some defects. Even CPUs have this too. For example, when Intel or AMD makes CPUs, they pick the ones that happen to be made well. The ones with the less defects can clock higher, and therefore cost more money. The CPUs with the more defects get clocked lower, and sold cheaper. It's gotten to the point where some companies are disabling cores. ATI and Nvidia first did this with their videos cards, disabling pipelines that were bad. Now AMD does this with their Athlon and Phenom CPUs, by disabling 1 or even 2 bad cores. Good news is that, many products were sold without defective cores or pipelines, and if you know what you're doing, and lucky enough, you could turn cheap products into expensive ones.
Yea I derailed myself. Anyway, after messing with Android on my Kaiser for 5 hours, I decided it wasn't ready. There's 6 issues that bothered me. Doubt any of it is related to bad nand blocks.
#1 Random features don't function unless you restart phone. Couldn't play MP3's because format wasn't supported. Restarted phone, and now I can play MP3's. There's a lot of instances where restarting the phone will fix a problem, but that brings me to the second issue.
#2 Restarting phone can cause it to not boot. Wouldn't be a huge problem if I didn't need to restart often, but I do. Usually, pulling the battery and holding the power button for a while, usually fixes it for me.
#3 Random freezing. You never know when your phone will just freeze. I got it to freeze when changing my ring tone.
#4 Installing applications must be in internal memory. A specific Android related problem, but annoying as hell. There's a solution to this, but it requires me to partition my SD card, and format it as ext2.
#5 No offline GPS. Again, specific to Android but something I can't live without. I heard Ndrive can do it, but I'd rather use the GPS that comes with the Android. I'm sure there's a way around it, but no good step by step guides to do it.
#6 Can't send audio with texts. I'm not sure if this is a Android issue, or if I needed to restart my phone. I love being able to send pictures and music formatted in the AMR format to friends, but for the life of me I couldn't select any AMR audio to send with texts. I could attact pictures with no problem, but couldn't find any of my mp3's or amr files. The same could be said about changing my ring tone to a mp3, as it just couldn't see it.
Did what i said to you in the other thread help with the sticky boot, and the lockups?
You mean the 3.29 boot loader? It still happened when I flashed it. Though, I did notice that Android booted faster, but that maybe my perception.

Its not illegal in america, it IS undoubtably illegal in lots of europe... its obviously illegal to exploit that to do malicious things... but whatever, the knowledge to do so is obviously NOT illegal, I'm VERY tired of that argument... that kind of info IS on this site... also, claiming illegality in the US will require citing law for me to really take ANY credibility in it...
*once again, I'm only promoting the KNOWLEDGE to be able to modify this, not the actual act... obviously there are a TON of scumbags that want this info to push devices illegally in the EU, but I personally could give a crap about them.*

As for the knowledge how to do it, it took be approx 5 seconds to put a search in to XDA's search box and come up with the results how to do it. Try it yourself instead of complaining about it.

I've searched, and used good forum etiquette, no need for the harshness, i've tried the single piece of software available that isn't INTENDED for the Kaiser, and I couldn't get it to work, also couldn't find any reports of it working for the Kaiser. PM me if you have any other info.
Please PM me too. I've performed the same searches and haven't found anything useful.
Actually changing your IMEI in order to get a service you have not paid for would be fraud, which I believe would be a felony charge at least.
There are US laws on the book regarding changing electronic "serial numbers" on mobile communications devices. They don't say IMEI (this was to deal with ESN cloning fraud in the late '90s with analog cell phones) but if you actually read the laws as they are written - you'd see they could easily interpreted a lot of different ways.
And in todays climate of anti-terror paranoia, I'm sure that changing your imei might also be construed as an attempt to avoid legitimate surveillance, i.e. wiretapping, which uses the imei in order to intercept traffic to and from a suspects device.
Not that i'm being a killjoy, I just had a look for ways of changing imei, and found a few ways of doing it, i'm just about to point anyone in their direction, since i'm in the UK

[Q] Clarifications on R800x Rooting Status

I know all of this has been covered but when searching all the threads I found were from last year at some point so I figured I would see if there was any new news that I just wasn't finding with my search terms. I apologize in advance if I put this thread in the wrong place or didn't follow the forum format in some way.
Basically, is the Verizon version of the Xperia Play, R800x with 2.3.3 still locked and there is no way to root this phone now? Maybe I misunderstood, but I thought the Supreme Court or something had ruled that we were legally able to do what we wanted with devices we owned? Does that not apply here or am I crazy? Let me guess, I inadvertently signed all my rights away by clicking something that automatically means I agree with whatever restrictions they wish to put on me, am I getting warm? Lol.
I knew I should have done this earlier but I honestly wanted to give my phone a good run stock before tinkering with it. Now that I am having to delete just about every app I have downloaded on my phone, including games I paid good money for, just so I don't get continuous memory warnings mostly due to updates for the preinstalled software that I never use that Verizon saw fit to saddle me with, I decided to look into rooting it only to find that this is no longer an option. Honestly, I am fed up with this phone, Verizon, the whole nine yards. Excuse me while I rant a bit but I wish I have never upgraded to a "smart" phone and I am seriously considering dropping back to a normal plan without all the data and use my old, reliable Samsung Flipshot. It was a phone and a camera and it did both very well. My Play is supposed to do all sorts of things but it does nothing well and even when I am inclined to surf the 'Net or play a typical game or even txt I am constantly bombarded with the popup that the app has stopped responding and do I want to Wait or Force Close. It honestly smacks of the Windows 95 and 98 days when nothing seemed to work right and the BSOD was a common, everyday thing. Ok, rant over, I apologize.
Seriously though, is there anything I can do to stop the slow, inevitable death of my phone? I have uninstalled the largest of the updates for most of the programs I don't use like the Kindle app, some sort of "office" app and a few other updates that were over the 10mb mark but is this a viable solution? Are these apps just going to update again later or harass me with notifications to update? What the hell happened to the 250mb of extra space I had before and why can't I get it back by deleting the apps I downloaded myself? When my phone was new I had all kinds of room to do stuff and had many apps installed that I rarely used but were very handy when I needed them, now I find that I have to delete anything non-essential just to get my phone to operate on a somewhat normal level. Is there anything I can do to fight this and get back enough memory to make my phone fun and somewhat useful again? Any suggestions would be greatly appreciated.
I guess I am just very disappointed with my first foray into the "smartphone" world. I honestly feel they are pushing the technology too far to fast since it seems almost like your phone is only something cool when it's new sitting on a shelf, then when you get it home and use it, it turns to crap in you hand. I suppose I am just angry over the whole situation and I feel sort of cheated. Maybe I misunderstood something somewhere but I thought these cool little gadgets were supposed to make life better and actually be useful. Then again, maybe I am just getting old.
So is there any hope or am I stuck with this for the time being or as long as I am stuck with Verizon in my rather remote area?
Read my sticky thread on "R800x Users: You've got Custom ROM questions? I've got answers." It still applies, at least until May 1st when you get an update.
In short: you can root your phone. There is something else called a bootloader that remains locked that controls whether you can use certain custom ROMs and kernels. There is a paid way to unlock it which gives you more access. There are quite a few custom ROMs you can use with a locked bootloader that will improve your phone's performance, and even more if you unlock the bootloader.
About the locked bootloader thing, Verizon can do that because they subsidize the cost of the phone in your contract. So, technically, they "own" the phone for the contract period and can dictate what you can do to said hardware.
You need to do a bit more digging. You can do a LOT more than stock.

Thanks for the info. I skimmed through the thread but I wondered if it still applied, good to know that it does so I'll go back and read it in detail. I guess I understand the Verizon thing. This is the real cost of buying my phone for a penny off Amazon, lol. Again, thanks for the info and I will definitely check out the info on rooting my phone, even if it's not totally unlocked. As long as I can get rid of most of the bloatware, I will be satisfied with that. Not really looking to make my phone do anything more than it does now, but improving it's performance and storage is definitely my motivation so hopefully something along those lines is still possible. Thanks again!

Well, I paid the unsubsidized price for my Play (~$500 if I recall) so I wouldn't have to sign a contract, and they still won't let me unlock it, not that that stopped me...

Technically you pay for the device but Sony holds the rights to what is contained within. You don't own EVERYTHING in the phone. Just the right to use it. Sure its in the Terms and Conditions

Well even with Verizon's meddling I was able to root my phone even without unlocking the boot loader. I got Titanium Backup installed and was able to remove a lot of the bloatware on my phone and free up a lot of memory. I wasn't able to delete all that I wanted but I was able to get back about 100mb of phone memory with just the things I did delete and that is good enough for me. The phone is acting normal so I guess I did everything right and didn't do any damage and I got the space I needed so I am pleased. Maybe down the road I will want to do more to the phone and workarounds will exist then but for now I am happy with what I have achieved.
Thanks again to Netizenmt and all the people who posted the information listed in your sticky. It was a great help once I calmed down, dug below the surface and did some more research.

Invasion of privacy

I was recently contacted by an old friend to help with an issue. He was a victim of privacy invasion on his S4, hidden instances of webcam and phone cameras, exporting of personal information, etc. Now he has come to me for help. I have looked at his logs and whatnots, but nothing really stands out. So, I am wondering if any of you have experienced the same problem? If yes, please provide me a complete list of all the apps you have installed on your device. Since I do not own an S4, it is hard for me to create the issue. The only answer is to get this community to pool together and get me the device (which would allow me to dev for the S4 and bring the greatness of the Lightning Zap! kernel), or for you guys that have experienced it, to help me find a common link.

Hey man! How goes it? I would love to have an S4 but it's just not in my budget right now...but at about 600 bucks (with no contract) who can afford it...lol
Although, I am up for my new every 2 upgrade... but it is for AT&T, and I'm not sure of the compatibility between the i9500, and the AT&T model (not sure of the exact model number).
As for the invasion of privacy issue, I'm trying to get more details on it. But I'm really thinking the malicious code started on his PC and drifted to his phone. And if it's the trojan I am thinking, then it attacks usb devices by making all the contents of that device hidden and appearing as if everything was deleted. Easy to get rid of, and easy to fix provided you have admin level access. Oh, and it was specifically made to attack Windows 7, but can leak out to other versions of Windows. Reason #1 to switch to Linux: Hackers HATE Windows and Bill Gates! lol

I mean, what were the indications? Like, what made your friend say "Man, I do believe my privacy is being invaded." You say nothing suspicious showed up in logs, the instances of camera and data exports, etc were all hidden... what gave the indication that it was happening?
A friend of mine recently had a very similar problem with his iPhone.
We quicly determined that the answer was that his phone was cloned using a scanner, which gave the bad guy power to hack into the device at the ESN level. Very hard to trace in any kind of logs, especially since the bad guy would have the ability to purge logs.
Your buddy might have someone similar. My friend was in Russian when this happened though, much less common in the US.

I asked him for more info and specifically what led him to believe this has happened. I am waiting for his reply. Here is th main snippet from his initial email:
I have been the victim of a very discreet but maddening invasion of privacy through my phone and also my PC and laptop computers via key logging, hidden instances of webcam and phone cameras, exporting of personal information, etc. I believe it to be a reoccurring problem via persistent data, local and cloud based storage, and corruption of my MBRs on most of my storage media. I know enough to be dangerous, but have yet to find any significant marker that points to faulty reflash process at least on my telephone.

He gave me some good logs, but I really don't have much to go on. With the statement about his MBR's, I think his computer was actually attacked and subsequently, his phone and possibly other usb devices have been compromised...
He has MBRs on most of his storage devices?
But I think he probably got Ratted on his computer, the guy controlling the computer saw he had an android phone and installed an android rat onto it when he plugged it in next.

[Q] HELP - child wiped out phone (brick?) and mom needs help...

hi everyone! I am seeking your expertise as I came upon this forum trying to help my son fix his phone. He's only 11 years old- but as we call him at home our "tech guy". He got a brand new HTC One M8 (carrier is ATT) yesterday and 3 hours later - the phone was "bricked" as I have been told. Apparently, (these are his words) he "unlocked the bootloader using HTCdev, then flashed twrp, then flashed supersu.zip.
I have no idea what any of that means but apparently he did something wrong because his phone is not working and we don't know how to fix it. If you have any compassion for a frustrated Mom who's trying not to be angry with her son -- I would appreciate any advice you can give on how to fix this.
I have attached a picture of what the phone looks like when we turn it on. I also posted this under the ATT forum too.
Thanks in advance for your help!
You bought your 11 year old son an M8?
Do you adopt?

Going by the pic, the bootloader has been relocked. So that's a problem. The bootloader will need to be unlocked again. I would suggest heading over to Youtube, as I have found video tutorials the most helpful when I was learning this stuff. There are plenty of videos that are even specific to the M8.
Edit: I should also point out that a phone can almost always be saved/restored if it still powers on. So don't panic. It would probably be in your best interest though to find someone experienced to fix it. Trying to explain the process to fix it here is not going to be helpful to someone who doesn't know what they're doing. If you can't find someone experienced, then my best suggestion, as stated above, would be to watch some Youtube tutorials on unlocking/rooting the M8.
Okay. In all seriousness.
When was this screen grab taken? In other words, is this your current position with the phone?
Relocked... etc etc
Are you in the US on AT&T?
Your tech son needs to restore ATT backup.. Hopefully someone in that forum has it

UPDATE on my son
Thank you all so much for your responses! It is much appreciated. Believe it or not - this kid fixed it all by himself. Basically (remember I am not technical) he unlocked the boot loader then flashed a ROM onto an SD card and was able to load. Don't think I worded correctly - but I think you know what I am talking about -- it's fixed and working fine. WHEW!!
I guess he "retraced" the steps he did last night and was able to get it. Actually it's strange the first ROM he put on wasn't allowing him to find or pick up wifi. He found another and got it. This kid is good!
I will certainly keep the info to this forum handy because something tells me that I will be visiting again with this child..................
Have a great evening!!
p.s. I typed the wrong key -- he's 12 not 11 And - sure I'd adopt! But he did save up his own money to get this phone and only wanted it to do these "cool" things as he says to it.....rest of my family - we are simple and use Iphones -- sorry.
All I can say to this is Wow!!

I'm glad to hear everything worked out for you and your son.
It's great to know that you're letting your kid tinker around as he is. I know these are quite expensive devices, but we often do learn from our mistakes, and that is even more true when it comes to technology. I'm sure that I have a bit of a bias being a software developer, but tech is such a huge part of life now, and that is only going to become more so with time. So getting an early start as he is, your son is going to have a leg-up in the world, even if he doesn't choose this type of field as a career path.

Agree! But keep an eye on him, so that he sleeps from time to time. And hide your car keys!
Please don't create multiple threads asking the same question.

Thanks!! He's very into all of this stuff and always has been from a very young age -- started with Legos at 2. He doesn't play sports and this is his "thing". He really LOVES all this stuff. He's actually really good and understands most things. As you can see - we certainly have issues now and then but overall we certainly let him "tinker". I really should write stuff down so we can laugh about it in about 10 years. We tried to limit his Internet time a couple of years ago and added a password on his computer that we had to input on his computer to gain access. Little **** put a keystroke logger on the computer to get the password. Then he somehow modified the main password screen to say PENIS when we logged on. The stories go on and on....... We will let him continue his technology building and hopefully he really have a bright future in technology!
Thanks for all of the input and support from this forum!

I was the same from an early age and always have been. I have taken apart or modified more household items than I can think of. I broke a lot of stuff messing as a kid, but now I have a lot of knowledge and can fix almost any thing properly.
It seems you are not so bad yourself with the technical stuff as most moms wouldn't have a clue or even be able to repeat what you have explained here.

temp sensor work around

So I have finally figured out that my z1 compact isn’t charging because the battery temp says -25.9 c. I was hoping someone somehow has figured out a way to turn the battery temp throttle off or disable it. I have already seen the write up on how to bypass with a wire but would rather not go that route. There has to be a way to just disable it. I know I'm not the only one dealing with this and Sony has just decided to ignore all of us. Thanks in advance guys.
so after numerous emails with Sony over the past two days I have come to terms with the fact that they suck. Every email is answered with "Regarding your previous Emails, we truly sorry to hear about this inconvenience with your device battery, however, we regret to inform you that if you already had opened the device this is considered as tampering. And Sony™ not longer will be responsible of it, the device will not be touched or evaluated by our repair center staff not even by paying." All I'm after from them is just an explanation as to how I can go about fixing this myself. No way would I pay them to look at it or fix it considering they know of this bug already. Seems like a crappy way to deal with your customers. If there is any way some one could point in a direction that may help that would be great. I'm just not sure where to look. I know there are countless custom ROMs and maybe that would be where the temp sensor could be bypassed? Any thoughts on this?
