[Problem] Tf300 randomly reboots itself every few minutes after JB upgrade. - Transformer TF300T Q&A, Help & Troubleshooting

Hi guys
So I bought tablet here in the UK about a month ago and apart from being sluggish on ICS (seems, everyone knows that problem) everything was fine. The JB OTA FW has rolled out and I upgraded and shortly after that TF300 started to play around by randomly rebooting itself every so often. Recently It got so bad that it happens all the time I mean in less than every 5 minutes.
I am gonna take it back to the shop but I am curious if any of you had this problem and if You know what's causing it...Ohh.. forgot to mention that obviously I did the Factory Reset and it didn't help...
I have to admit that after my faulty device and so many people had on this forum I will never ever unlock it after i get it back fixed/replaced...It's just not reliable enough to trust Asus on that especially if it cost so much money to fix it after ...

i ve got mine for over a month now. First ICS and JB later, I honestly can remember it ever rebooting

When I read your issue, the first thing I thought was how glad I am that I'm unlocked and running stable builds rather than the stock ASUS stuff.
If the issue is hardware related, ASUS should cover it under warranty regardless of locked or unlocked. Unlocking it didn't cause the hardware to fail. If it's a ROM issue, you can easily re-flash or try another. It's a win-win.
Regardless, good luck with your tablet.

After doing factory reset did you try your pad without restoring any apps? It could be that an app you had was causing the reboot, it seems strange that it didn't do that on ICS and it does on JB.

Yes i did..but then again it was working fine on ICS so can't be a single app besides it usually reboots when the screen goes off...I started to think that it may have something to do with the bootloader since one it didn't even boot but stopped on asus screen giving me some message about bootloader error etc.(can't exactly remember what it said)..one way or another it is strange that only some ppl get this random reboots and for other jb is working fine so I'm gonna get it replaced or money back and maybe but tf700 ..i was gonna unlock it and flash custom rom but if problem still occurs then I'm completely screwed on money...

g2x problems

Everybody seems to have some problems with the phone. I was wondering what all the common problems with the phone are and also whether rooting fixes the problems or not.
Yes! And no!
Well, my first G2x had problems... It kept shutting off by itself, so I got it replaced. The past 2 replacements have been really good, no problems whatsoever. I shipped my 2nd one back because it came with part of the body scratched. The gingerbread update didn't really do anything for me, other then the updated baseband.
Reboots, shutdowns, over heating are all based on the device itself. Some have it, some don't.
Also, screen bleeding isn't THAT bad.
And CM7 is amazing, so why not root?
So far, the only problem I've had was that the LG updating tool soft bricked my phone. But, at least that updated the baseband. I've not seen any random reboots at all in the month that I've had the phone. Aside from the FFC camera issues that are hopefully still being worked on, this thing has been pretty good.
I bought a mint, second hand G2X and the only problem I had was with the flakey LG updater. Once I got it updated (within 48 hours of receiving it) it has been nothing but stellar. Maybe I am lucky but remember, happy people don't post much to forums such as this. But people with problems can be very vocal. That doesn't downplay the problems to those who experience them, and they have my sympathies, but I would say the majority of G2Xs out there are performing as they should. This is my fifth Android phone (last one a Nexus One which my wife now has). I am using it unlocked ($3.00 unlock code off eBay) in Thailand with 3G service on 2100 and and I couldn't be happier unless the phone had been free. By the way, I am using it stock GB 2.3.3. For now, I see no reason to root it until an exploit has been discovered so I can root it without flashing clockwork mod. The NVFlasher process kind of concerns me, and I am no noob when it comes to flashing devices.
I'm still getting reboots and freezes even after the update. I'm on my 3rd replacement. Also, still takes forever for the gps to lock. Love the phone... when it works.

Have you tried running the phone clean without apps? Then add apps back one at a time, run for a while, and then add another one? Lockups and freezes are usually errant apps, and not the hardware's fault. My GPS locked from a cold start in 5 seconds.

What can I do if I'm tired of my G2X 6 months in?

I've had the G2X since release. It was my first smartphone, and so maybe I wasn't entirely sure what to expect. (I probably still don't have a real idea.) I've had the freezing/rebooting problems since about 2 weeks in. There are times it just won't "wake up" or just automatically reboots itself. I'm way outside buyer's remorse, obviously, so what kind of options to I have? Can I still get the phone replaced by T-Mo, to hopefully get one that has less reboot issues?
In case you were wondering, I have modded the phone to see if other ROMs would fix the issue, but they have not. It seems like the freezing issue will be gone for a short time after wiping and flashing a new ROM, but then a couple of weeks later it's back to how it was. Any advice? Maybe try to trade it out on CL or something?

You have one year of manufacture warranty from the time you buy it. I suggest you call T-Mobile and ask for a replacement.

You didn't mention if you did the GB upgrade and the new baseband. If you are really tired of it just send it to me in Thailand free. I can use another phone for testing rom builds.
Hah, I did do the official GB upgrade before I started putting ROMs on it. I was basically hoping that would fix my issues, but it didn't, so then I started in on ROMs. Currently running the latest Weapon, which I like, but the reboots/freezes are wearing on me. I'll try to call T-Mo.

The phone is defective. Get it swapped out under your warranty. Mine has only rebooted and sod once the entire time I have owned it. Occasional reboots and sod are normal for Android (usually a bogus app running havoc on the system). If you have frequent problems you have something wrong with your device. If you have tried running stock without installing programs and still have problem you definitely need to do a warranty replacement pronto. When you get your new one run it a few days without adding any apps to make sure it is okay. Then add apps slowly so if one starts causing problems you can pinpoint down easier and zap it off your phone. When the G2X is running correctly, it is one of the best Android devices on the market today.

Awful performance issues

Is anyone else having terrible, and I mean terrible performance all around with their TF300s? Mine is barely functional, much less efficient and stress free. All of my internet browsers are always force closing after freezes and crashes. I have to go through several force closes even for a google search to get done. My launchers (Nova and Apex) are always freaking out. Random page swipes, random apps getting opened, random widgets getting opened. Whenever I try typing anything, its always massively behind me, either having each key press appear individually at a slow rate, or just appearing in chunks at an equally slow rate.
It was the same on the stock ROM, and not much has changed since I switched to this Blackbean 6 ROM. I have tried overclocking, but this exacerbates the problem, causing random touches and eventually a complete crash and reboot. I am thinking my hardware my be faulty or something. Is there anyway to check this? I'm pretty sure my warrantee is out the window now since I unlocked the device thinking the stock ROM was the problem.
I got this around this past Christmas, and I am really kicking myself for not picking up a Nexus 7 instead with how this TF300 has performed for me so far. I have pretty much defaulted to my phone for 99% of uses because my TF300 is so unusable, and in fact the only reason I am posting from my TF300 now is because my phone is dead. I can't be the only one with these issues right? I am trying my hardest to like this device, but I just can't do it.

Try using CleanRom Inheritance. Custom ROMs are supposed to drastically increase performance.

I RMA'd my tablet for ghost touches, and ASUS North America fixed under warranty even with the thing being unlocked. If you're going to go that route, you need to be pretty certain that it's a hardware issue, though. And definitely flash back to a stock ROM and check to be sure you can reproduce the issue, and include clear instructions to be sure they don't blame it on user error.
I ran BB6 for a while as my daily driver and never had much trouble. Over time, I started dropping WIFI "on wake up", so I switched back to a stock-based ROM (CleanROM Inheritance, as recommended above). No issues since.
Good luck.
+1 for Clean ROM.

Thanks for all the suggestions, guys. I'll be checking out that CleanRom you guys suggested, and report back here with initial performance and performance after a day or so and see if it fixes the issue. Oddly enough, the XDA app is one of the only things I can use on the device with almost no trouble.

Would you happen to know anything about their warranty policies? I got mine off NewEgg but don't remember seeing anything about a warranty at all.

I got mine from Amazon, but I don't think that made a difference. I think the initial warranty is one year hardware and software, and that unlocking voids the software warranty.

Is it really just the software warranty it voids? I haven't done it yet but I have read the legal mumbo-jumbo and it basically says that once you unlock it the device is no longer in the original manufacture condition and therefore not covered by the warranty. I don't think it specifies hardware vs software. There are some people that are able to get their device fixed under warranty despite being unlocked but I don't think they have to.

I will return my unit today, NewEgg gave me the return shipping label. I recorded a video on how to replicate the issue and even write the steps to replicate to be sure. I hope this will replace it even if it's unlocked.
EDIT:
I received an email regarding my RMA from NewEgg:
Your RMA return has been posted, which means that the contents have been verified and your return has been approved.
If your RMA was processed for a replacement, a replacement order will be created for you within the next 1-2 business days.
Actually I just want to avoid inconvenience that ghost touches will get worst cause I only got the ghost touches when from screen off state and you hold the screen then pressing power button you will have ghost touches holding the upper right corner of screen which will prevent you from unlocking the device and can easily resolve by power off then on the screen again. Well I hope I get a bnew without any ghost touches problem coz I miss playing games especially I deleted the OS of my kindle..

Reboot issue with JB 4.1.2 vzw newest update on Razr HD

Hey so after a few days of the new update running OK I started having random reboots! I noticed on a few other sites people complaining about the same issue of reboots multiple times of the day! Just wanted to let everyone know a possible solution to the issue! I have went through multiple FDR's and did come to the conclusion that the random reboots for my phone were associated with a new update to the chrome browser and were easily fixed by uninstalling new update and telling it not to automatically update so hope this helps anyone who may be having the same issues!!!
Well so much for that after trying everything its back to rebooting again? I love my phone but seriously considering putting it against a wall!!!

Never had that issue with the new update. Try doing a factory reset or try the new fast boot files to start fresh. Not sure why chrome would be an issue.try the chrome beta version but I suspect chrome had nothing to do with the reboot just a bad initial update.

Finally broke down done a fast boot to the new files all is working seems OK anyway know in a day or 2!!!

My Wife's phone is doing the Random Reboot thing since the 4.1.2 update as well. I did a Factory Reset on it and it still does the same thing.
I suspect an application is doing it? Because I put the phone in Safe Mode and it never rebooted while in Safe Mode.
But I have No Idea of how to tell which app is doing it, other than to uninstall a random app after every reboot to find out which one it is.
But I would like to try this fast boot option? I know how to get the phone into fastboot, but which files are you redoing? What exactly are your doing ?
Have the same problem. I have done:
SBF 4.1.2
FDR
WIPE
Even tried running a parallel rom with safestrap (bakatang)
The chrome thing did not work
Keeps freezing. Seems the problem is way worse when having the phone play some music.
I am just about unlocking the thing and SBFing back to 4.1.1 but not really interested into unlocking the bootloader. That would be the last choice for me.
If someone knows of some way to fix this, please help, this used to be a great phone...
No problem here with the sfr rom... used for over 1 month now and no problem and my system is always fast...

I've been running some tests for about a week now since I got my RAZR and the results are interesting... I've had lockups and reboots multiple times a day, most often while doing something involving sound i.e. listening to music or playing a game or video. I've tried stock and custom 4.1.2 ROMs and custom 4.2.2 ROMs and it persists so I'm inclined to say its either bad audio software or faulty audio chips. This is everything I've done:
1. turning off sounds (keeping phone on vibrate/silent) pretty much eliminates the random lockups/reboots I got from receiving multiple texts or calls at once. I noticed if I bombarded the phone and made it ring a lot it gave the same results as listening to music but if its just a text or email or call here and there during regular use it the phone works fine.
2. Listening to music, either streamed or local from phone/SD storage and through headphones or speaker, would cause skips and audio cutting out. After a few minutes of this the phone will lock up completely and reboot itself. Strangely enough it happened only rarely or not at all while streaming music via bluetooth to a stereo.
3. I don't think its anything kernel related or if it is its not causing visible errors or wake locks. My battery seems to be just fine through all this.
4. I have tried multiple music/video players, put my SD card with music in another phone and the music plays fine, stock ROMs with nothing disabled/removed still has the issue, custom ROMs debloated and modified also have the issue. I think I've just about covered every base I can as an end user to track down what's causing it but I'm open to suggestions.
I have a replacement scheduled so I will see if that fixes it, I have seen this problem reported quite a few times all over the interwebz but there are also a lot of people not having the issue either so idk. If there are any Devs or anyone skilled in android-fu that can read logcats I will be more than willing to get those for you. Sorry for the essay everyone lol
tl;dr Like others I have freezes and reboots from what seems to me to be an audio software/hardware problem, either built in or from the 4.1.2 update

I am almost sure is kernel related bc I did not have problems in the 4.1.1 sw.
If someone that has an unlocked bootloader could install 4.1.1 from an sbf and tell if the problems are gone, would be great!

I am not doing that bc I do not use custom roms so dont want to unlock BL. If someone has, this could help much. It is different from using safestrap, because safestrap uses the same kernel, from what I read.

one solution that has worked for me is silencing the phone or putting it on vibrate and I haven't had a freeze or reboot in almost 2 days... the problem seems to me to be related to audio/sound and not listening to music or watching videos along with silencing ringtones has put a stop to it which kind of confirms my suspicions... I will try and flash back when I can but it'll need a day or 2 of field testing to confirm if its a solution
Sent from my DROID RAZR HD using Tapatalk 2
I can confirm that audio stuff just does worse to the phone. However, I have not had your luck when silencing. Keeps rebooting no matter what. Please let us know when you do.

looks like a negative on the SBF, tried to restore 4.1.1 and it failed halfway through the flash, now won't turn on... working on reviving it... I really need to replace this thing as its been nothing but a PITA since I got it
old school post from my Thunderbolt via Tapatalk
wow that sucks. I recall reading somewhere that you could actually downgrade your software version if you have an unlocked bootloader.what is the error you are getting? Tried using RAZR utility 1.1? Won't it turn on at all? Maybe a discharged battery? Hope we can solve it

got it revived with Mattlgroff's new 1.2 utility, was able to force it to fastboot mode... the problem seemed to be some kind of partition error, I tried redownloading the sbf files thinking it was a bad file and got the same error so idk what it is since I'm on stock unrooted 4.1.2. My bootloader is already irreversibly unlocked so that won't be a problem lol but I am a n00b to RSD Lite and Moto devices so I'll tinker with it more when I get some free time
edit: I did have a Maxx HD way back at launch for a month or so running stock 4.1.1 and it ran perfectly, so my idea is its kernel/codec/software related. Hopefully a custom ROM (or hell even stock) with Hashcodes Qcom kernel will fix the issue we're having

I talked with vzw service, the assistant said that 2% of the phones were having this issue, wich for this kind of technology is a pretty big number of phones. Suuggested to send it to Motorola but since its rooted its almost sure not to be replaced by them. What is strange is that not everyone is having this issue. I would be almost sure Motorola is going to release a fix for this, but would not count days. Getting kind of frustrated with this phone I used to like so much. Thinking of going the htc route bc this is getting unbearable.
Any news in this? Anyone tried a new ROM that could solve this? Or even a fix?
... or just everyone had another phone lying aroud...

My wife & I both have this phone and still are constantly being rebooted. This is even after the software update. I have been wiped, factory reset, and everything possible, but I've not called for a replacement yet. Normally I havea worse luck with those.
Wife used to love this phone, now she hates it and hates we changed from AT&T to Verizon since we have no backup Verizon phones. At least we could take the sim out and go to the iPhone that's floating around the house when the phone went to pot before. Makes me really hate suggesting that we go back to Moto phones since that's all that I've used on Verizon.
Wonder if big red will get the new HTC One....

G930F - crash bootloop issues

Hi everyone!
I have a international version of the s7 that I bought in France.
Since 1 week, my phones crash randomly and also every time I try to update or download an app on the store. It happens with two different roms (superman and galaxy project).
But not happy to only crashing, it also bootloop after it, sometimes during 20 minutes before booting correctly. And it makes the phone's temperature going up a lot. With all the issues with the note 7 heating and blowing, I fear for my s7.
Also, I can't just return it, because I'm not in France anymore, and it costs a lot to pay the taxes if I want to send it for a check (especially if they do nothing on it)
I was wondering if the cpu clocks on the roms has something to do with it.
If you have any suggestions, I'll wait for it.
Thanks

Hi
Do a factory reset , do not restore anything see if it works ok , if so then it maybe an app causing the problem
or you could flash a stock rom to test the phone and make sure there is no hardware issues
Thank you for your answer.
I'll take a try this weekend with a stock rom as I have the issue with 2 custom roms so far.
If anybody has other ideas until that, please let me know
Little feedback. I flashed the stock Samsung rom two days ago and it seems to work fine for now. But it was also quite fine with the custom rom at the beginning, so I will do another feedback after one or two weeks.
Well... The phone froze and rebooted 5 times in 10 minutes after trying to update some apps itself...
I had the same problem. At the end I was not able to boot Android. I had to claim my cell phone to seller. After one month it was repaired. The final verdict was SOFTWARE problem. They said that EFS was corrupted. One of Samsung firmware has bug which cause problem with EFS.
I also had that problem. I also had to send my phone to the repair center. In my case they replaced the mainboard.
I bought one early september and after two weeks it started doing just that. I tried everything, then sent it to the seller (ebay seller...) and the repair shop couldn't anything about it. I only got my money back yesterday. Back when I invesitgated the issue, nobody was talking about it. So since I liked the phone, I bought a new one from another place (less shady) yesterday... I now think I shouldn't have. Anybody knows more about this ?
Edit: I'm thinking that if I root the phone and backup the EFS and all sensitive partitions before starting using it (or even getting updates) I should be safe...
Yeah, that would be great, but your KNOX will be 0x1. So you will have problem to return this phone back with status 0x1.

Hello everybody,
Sorry for the very late reply. I actually sent my phone to another shop here in Japan. But this week, they send me a mail to say that they were not able to fix the issue. But still they taker me 50$ for the time...
I was thinking about buying a new one, but now that some of you are talking about an EFS issue, I'll try to fix again. I will look for some tutorial for that, but if you know how to procede, just reply here
Merry Christmas guys !
hello, i've been having a similar issue.
My phone would be fine for 2 weeks, maybe a month then Suddenly it would reboot to no end, it even reboots from TWRP.
It doesn't reboot while in Download mode. Then what i do to fix it is flash a stock rom from ODIN, sometimes the first couple or 5 times it will reboot during initial first boot up of this stock Rom. I would leave it alone for a while like half day then try it again in the evening or the next day.
Today for example, it started boot looping late last night and I installed Stock ROM with PIT FILE and Nand ERASE and Repartition ticked, boot loop, again, boot loop, tried it again, also rebooted before it started up to stock recovery and factory reset. Then it started up fine and has not rebooted so far.
But this has happened many times and it'll happen after 2 weeks or 1 month. When it does, i first go and delete cache and delvic cache to see if that would fix it, but it doesn't.
Right now it works, but for how long i don't know, when it works, everything is fine with the phone, no imei or calling or heating issues.
I can't guess whats wrong, is it really EFS that got corrupted but not fully but eventually its finding a problem and causing boot loops or something if that makes sense??
