Hello all,
I bought the Atrix around 6 months ago and I have always had the same problem I'm about to describe. First I should mention that I used to have a stock rom and stock radio (77.15) until a couple of weeks ago when I flashed Cyanogenmod and radio 77.30p, yet the problem is present in both configurations.
My problem is as follows: my battery life is mediocre. Without using the phone very heavly, I get around 7-8 hours until it shuts off. Since day one I've tried many different fixes to see if the battery improved without success. Now here's the fishy part: for whatever reason, every time I make a full wipe (when I was using stock I did it from the "reset to factory defaults" option, now I do a full wipe on recovery) the battery lasts an insanely amount of time, something like 24 hours or more.
Here's how it usually works for me: I do the wipe, I boot my phone and configure my accounts, the phone syncs and installs the apps I usually use. Like I said, that day the battery will last forever, last time I've tried this I reached around 31 hours before I plugged the phone back on, and it was around 17% still. Now, the next day, without installing any new app or using the phone for nothing different, I go right back to the mediocre battery life. For example, it just went from full charge to 88% for just 10 minutes of browsing the net on wifi, not even using 3G.
Like I said, this happened with stock ROM and now with Cyanogenmod regardless of the radio I'm using. I have calibrated the battery a million times, I've tried with Watchdog which didn't show nothing, the same with Better Battery Stats. I really need some suggestions on what to try because it irritates me that the battery is dropping so much with such a light use.
Thanks!
I'm getting also quite short battery life with CM7. I'm wondering what the reason could be. It gets down with 15% for just 5 hours without any phone calls. I have just whatsapp and email checking every hour. No other resource hungry applications. With the stock ROM and the same usage I'm getting around three days ~ 72 hours.
Well in my case it's the same but with both stock and others roms. I suspect it's a software problem because I get normal battery life when I do a full wipe.
Did you try to revert back to unlocked bootloader.
What I found strange is that somehow the indicator doesn't show the ratio mAhercentage. On 85% battery the calibration battery shows charge 4030 mAh which is not 15% less than the full charge of 4200 mAh.
Well actually this problem has existed from before I unlocked the bootloader so I don't think that's the problem. And in my case the mah percentage is correct. It's like if somethings draining the battery that I can't find. Maybe is a problem with my carrier?
If the coverage is poor where you live then it is possible to get lower battery life than expected. Another solution is to revisit the application you use, try also to do a full wipe including formatting the internal memory card.
Go through this process: http://forum.xda-developers.com/showthread.php?t=1198333
You'll be good to go after that. Check also BetterBatteryStats here in xda, will show you what processes eat the battery.
Thanks but I've tried that when using the stock rom and it didn't help me. I think that solution is for a different problem as it's mainly to display the correct mah percentage, which is not exactly my problem. Also, CM7 already includes juggernaut fix.

Have you tried a different radio?
Yeah, like I said I had 77.15 at first and now I'm using 77.30
There's more radio's, check in General.
Ok, I flashed 77.36p and there was an improvement, I've unplugged the phone around 13 hours ago and I'm at 25%. Would you consider a good battery life for a light use? It's getting better but I saw many people crossing the 24 hour mark on their phones. Are there any other radio to try other than 77.15, .30 and .36 that would be worth it?
Do a full wipe in Fastboot & install Nottach's DarkSide and leave it with the stock kernel. I'm at 77% with 1hr 40 minutes screen time & 17,5 hrs standby..
P. S. I'm using the N_01.100.00R radio. Am in Germany, though on an at&t phone. Best radio so far.
Anywhere from 13-20 hours is fine but keep in mind it's all dependent on what's on your phone. If u have a bunch of apps pulling data from the internet or something ....I mean its all dependent on your phone setup.

Well, for now I'll stick with Cyanogenmod for a while because I really like it, but I have flashed the radio you've mentioned, we'll see how it behaves. Thanks!

I hate to start a new battery thread but I've searched, read all the ones out there, and nothing seems to have helped. I just got this phone late last week and I first upgraded it to the latest OTA, then odin cww and finally installed com rom 1.3. Let me just say I've never seen a battery drop this quick. I haven't even activated the phone on my account because I'm so scared of how quickly I see it dropping without touching a thing on the phone. I also noticed the following:
baseband version
S:i500.04 V.ED03
Kernel Version
2.6.32.9
Build Number SCH-I500.ED01
The baseband and build ED0? don't seem to match up. Would this cause the problem? How do I fix that?
Just so that you get an idea, I've had the phone disconnected for 5hr 30min and I'm down to 55% battery with a fresh clean install of com rom 1.3. I did the battery calibration and that's about the only thing I've even installed on the phone. When I hit batt use here's what I get.
Display: 52%
WiFi 26%
cell standby 15%
Phone Idle 7%
I've had android for about a year and have an incredible that I love so I know that something just isn't right with this fascinate. Any help is greatly appreciated.
Thanks,
Mike
my understanding is that the build and baseband don;t have to be equal, baseband is modem/radio and build is just the rom i believe.
From what I hear, the only thing you have to keep track of is using an eclair modem with a froyo rom as there will be issues...
You can try going to the ED01 modem (works better for me vs ed03)
I also had battery "problems".. barely get through 12 hours without needed charge with little use.
I just installed Green power app from market.. it seems to work similarly to juice defender, just is easier to configure for the noob like me, and is MUCH more limited. works on the basis of only turning on transmission intermittently.
Now I can go 18+ hours and remain above 50%.. 80% if I don't touch my phone.
Turn off wifi when you're not connected, my phone lasts 36 hours using juice defender to turn off radios when screen is off

The radio firmware makes or breaks the battery life on this phone. I've tried every combo of roms and radio firmwares. Go back to the DL09 or EA28 (my preference) radio firmware and recalibrate your battery bro. The eclair-era radio firmwares have proven to be much better than the newer ones.

Com Rom is built off of ED01 so it will say that.
ED03 is the latest build basically the same as ED01 just 3 fixed some bug that had a few phones stuck on EA28 if I remember correctly.
I haven't noticed much battery difference between the different modem/radios, personally it seems like the kernels make a bigger difference to me.
Also if you just clear the battery stars to calibrate the battery the battery gauge will be messed up for a couple cycles, best if you run it all the way down too. One of tie batteries I was calibrating in my phone said 0% for almost an hour before it actually turned off.
These phones aren't great on battery life anyways. One of the good things about using a kernel like OTB included in com rom is it allows you to use aftermarket batteries and still charge then in the phone. I get the Samsung batteries (I think they are technically for the epic), out of China for $2 each. Have 5 of them right now the wife and I rotate through. We also have two external chargers, we both just carry a spare battery to use if our phones die during the day.
Thanks for the tips. I think I'm going to try the different radio files and see if that helps. I guess I was just wondering why my display shows as if it's using so much battery and if that was caused by some other conflict. I've had phones with bad battery life but this is just crazy. From the time I wrote the first post (a little less than 2 hrs ago) I've gone from 56% to 36% with nothing installed or running. That's just beyond bad battery life. Something is hosed. I'll try the radios and cross my fingers.
Have you tried under the task manager and choose the ram manager do the level 2 clear, should close everything that is running, that helps me quite a bit. Also auto rotate can be turned off when you aren't using it that will help battery life too.

As was stated earlier, turn off wifi when you are not using it, that will help a lot. Also under wifi settings, advanced, and change the wifi sleep policy to when screen is turned off. And when you look at those percentages under battery use are not a percentage of the total battery, just a percentage of whatever battery use there is. So if you are losing 8% of your battery per hour, that 52% next to display just means display is draining 52% of that 8% per hour drain. Display is almost always going to be the top drain because of the super amoled screen.
^^^ Yeah, display is most of it. Turn brightness down (as opposed to automatic or full brightness) and see how that helps. If that doesn't help, turn off mobile data until needed, if that doesn't help (should do this anyway) recalibrate your battery and cycle it like 2 times. Give it a couple days, it will go back to normal.
Radios are the biggest battery drain, not the screen, I've used airplane mode and watched movies with four hours of screen on time and used 20% battery, all you need to do is keep wifi off when not in use, it pings something like every 20s trying to find when you're in range of networks, 3g is your second biggest killer...also do not use auto task killers, for reasons I'm too lazy to get into...lowest screen brightness setting helps some but I've found it a pain going into bright sun and having to change it, the auto dimmer works rather well

Click on the items in battery stats and tell us how long your display has actually been on. The display on this phone can fairly easily burn through 1%/minute of being on (in fact, doing the math, my phone's display is at just under 1%/minute right now).
And, personally, I hate JuiceDefender and those apps. They're not fixing the source of the problem, just doing a half assed job of duct taping over what might be tangentally related (while doing horrible things to syncing). Try to find what is _actually_ trying to keep the network awake if that is actually what is going on (the Facebook widget is known to utterly destroy battery life). Make sure apps are using Push instead of Pull notifications where ever possible (Pull uses an astronomically large amount of battery life in comparison to Push).
I get around 15 hours on any other radio than dl09, on which I get around 24-36 hours depending on how much I'm using to phone. Also make sure you turn off wifi when you aren't using it.

Ok, thanks to everyone. I wanted to give you all a quick update in the hopes that this will help someone in the future. I replaced the radio file with EA28 and wow what a difference it made. I now don't see the percentages drop right before my eye and I have a shot of making it through the day. I'm also pretty surprised by the amount of battery the screen uses up. My AMOLED droid incredible usually shows the display as using the least percentage of battery. I guess the super really isn't that super.
One question I do have is if I go back down to DL09 to get the better battery life, what's the trade off?
I haven't noticed any differences between the DL09 radio and any Froyo radio.

I flashed MIUI Lithium 360 yesterday and I've had a couple of problems with it. I'd post to that forum but since I haven't posted enough to XDA, I can't put this there. It's my punishment for using Search too often and correctly I suppose.
Performance was great all day yesterday after the flash. I let battery drain to 0% then ran calibrate right before bed. In 7 hours I was down to about 20% even though I was asleep. It took about 90 minutes of moderate use this morning to finally kill it. I haven't flashed a new kernel or modded beyond the stock ROM; still using KA7 radio. I believe Android OS was the big culprit in the battery monitor. (sorry no screenshot)
The other problem I'd noticed was that my WiFi would no longer connect to my home network. It was fine last night, but this morning, it listed my network in the history but said it wasn't in range. Confirmed problem was not with WAP/Router. I deleted the connection and tried to reconnect, it saw the connection again, but once I put in the WEP/WPA password, the phone resumed the message that the wifi network was out of range. To be fair, I did not power cycle the phone at that point as I was still waiting to drop to 0% on battery. (not sure if that matters or not - calibration tools don't say not to reboot, but they don't instruct user to reboot either) I'm sure I'll know more after I let it charge to 100% again, and I may update this post to report back.
I updated this phone from CM7.1 yesterday, did all wipes, formatted /system before flashing. Did let it sit and restored the Current theme all per instructions. I did not restore any apps to the phone after flash so previous apps could not be part of the issue.
I did use stock CM extensively on my G1 for years, but I was less than impressed with CM on Vibrant and found it to be lacking.
The battery will need a few charge cycles before it will give you better battery life. Just make sure you calibrate the battery when its fully charged. Now someone else in that thread had the same problem as far as wifi not working correctly. The best way to tackle this is to odin back to stock, root, flash a 2.2 rom then flash miui. Let me know if this helps.

changed my modem to KB5 and having less problems with wifi. Don't know if it's making a difference anywhere else. Battery use still a little high due to Cell Standby. Seems like it's eating about 5% per hour just idling. I will go through a few more charge cycles and see if it improves.
What exactly is the process kworker, and what does it do?
On two different custom roms (Shostock and Phone Bricker - multiple versions, even with latest v2.7), this process is KILLING my battery, to the point of 25-30% overnight with ZERO usage.... sending 1-2 text msgs in a row, I could watch the percentage drop 1-2% in that short time.
On STOCK rom with stock kernel, or Cherry Picker or Siyah kernels, I do NOT have this problem and I can get 24-36 hours of unplugged time with at least 12 of those hours being heavy to moderate usage... I can sit and post in Facebook for a solid hour and only go through 2-3%... but if I go custom, I'd lose 3-4x that amount of power.
I'm just wondering what I'm missing....
I know its with the kernel. It used to be a problem with Linux, but updates fixed it. I have a few kworker process that I to would like to get rid of on my phone... though, they dont wear down my battery like yours! Mine keep my phone awake for a while... thats about it. I am going to watch this thread closely to see what people have to say about FIXING this issue...
I'd appreciate that... I don't like being restricted to a stock rom just to get decent battery life.
Today I installed Phone Bricker v2.7 after a complete reset... simply loaded the rom, didn't sign in with Google, simply loaded an app to monitor usage and took a nap... in not even 90 mins, it'd already dropped to 92% from a full charge with no usage.
I'm seeing this type of behavior from both Phone Bricker and ShoSTOCK.
Am I doing something wrong?
Gotta give it a couple days to settle. Battery percentages will never report correctly for the first couple days after flashing a new kernel (and both of those ROMs include a kernel, I believe). It's been posted a couple times throughout this forum, but I know it's a little hard to find sometimes, so I'll cut you a break. See here for a recent example.
After a few days, then you can check to see if kworker is still killing your battery, and you'll have a much better idea.
Well, I'd run Phone Bricker for roughly 2 weeks, dating back to v2.5, and tried sticking it out through the "settle" time on v2.7 as well, but performance never improved.
Also worked with ShoSTOCK, also well over 2 weeks with no negligible improvement... my battery just kept being drained and it's taken me the better part of a month to narrow down this one process that is the culprit.

Mini update:
Live wallpapers, even if screen is off, will drain your battery like crazy.
Checked Facebook on 100% charge, was on for maybe 10minutes. Turned off screen for a little over an hour. When I checked my phone I had 90% battery. 1%/min drain? Hmm... I turned off tgeclive wallpaper and my battery is now at 83% after 4 more hours and some mild/moderate use of the phone.
Might not be news, but a great tip. Didn't have this issue as bad on stock GB, but I still refuse to run live wallpapers after seeing that happen.

Not all LWPs do this...only the badly coded ones.
I've never used LWP because I'd always heard/assumed it was a battery kill - can you recommend some that you know to be solid?
Thanks for all the feedback so far gang.... as for this stock rom, as we sit, it's at 16 hours off charge and I'm still at 66% with moderate usage, and that's just beautiful, I just wish I could achieve the same with aftermarket roms as well.
Anyone???
I'd went back to stock, and it was working AWESOME for about 2 weeks as far as battery life goes, but suddenly the phone would lose it's data connection, requiring a reboot. After the reboot the phone had no signal bars, just a 0 with a line through it.... 3-4 restarts later, 3G + data would eventually come back, but data would last sometimes 5 minutes, or 5 hours before stopping.
I was out of town for 3 days, just got back, and while on the road I lost signal so much that I had no choice but to pull over, fire up the laptop and download a new rom... I did a full wipe, factory reset/data, wipe cache and dalvik and was using Shostock v3.0. I had horrid battery time due to this and I feel after 3 days of moderate usage, it's had time to "settle" with no changes. Had ZERO data problems, but horrid battery time due to kworker.
Last night (roughly 12 hours ago) I installed Serindipity 9, and already right out of the gate, showing kworker just blasting the battery... this process is haunting me with the roms I'm installing...
I installed a new SD card for troubleshooting purposes... no affect.

don't worry you are not alone. seems like this kworker issue is going around and making lot of people crazy including me.
I tried removing all application which use some kind of timer. Still no go, the kworker comes back to haunt me too all roms - aokp, phone bricker, serendipity, even hell raised one
This issue has just about killed my ability to use any custom rom on this phone.... surely I can't be the only one affected???
I see in another post that this seems to be a hot topic, but then again there are so many others that seem to be flying with no problem....

Hey guys! I want some advice to check if this problem is normal or maybe its a manufacturer defect.
Anyway, I bought this phone about 5 days ago, and in the time I've been using it, my battery lasts about 7 or 6 hours (also it takes like 5 hours to fully charge it, which makes it worse). I thought it was because the stock ROM isn't very optimized, but later I started using cm 12.1 and it seems to last almost the same. Also, I started using an app called "current widget" that checks continuosly some info like the mA that is using at the moment, and I found that when I use it, it's mA is between 500 and 600, and sometimes it's like 180. Is this normal?
I'm worried because I've read in reviews that the battery of this phone lasts about a day and half and mine barely lasts 7 hours. Please, help...
Mine will last for 2-3 days if left alone. I'd download an app or CPU monitor to see what's running and draining the battery.
I repaired it already ^^ I just flashed official firmware again and no more battery draining and heating.
Battery draining could be many things but usually comes down to rogue processes.
Since android is java based over C, it becomes a garbage collector. Be sure to clean your device frequently to avoid internal confusion.
If a simple cleanup doesn't work, you can try to remove processes from loading at boot.
I honestly think that a reflash of your ROM is a bit extreme for a battery draining problem. I would try to exhaust every other avenue first.
I know, but I even tried disabling apps and it stayed like that. Also I flashed other roms and the problem didn't stop. I was going to claim my warranty and that's why I flashed everything again and somehow that solved it. I suppose my carrier modified the software somehow and that's why my phone had that problem.
Put your phone in airplane mode when you aren't using it. See if the battery drain persists. How is your signal? If your phone has a low signal, it will actually boost its radiation to try and keep the signal or establish a stronger one. This only is a battery killer and an issue that cannot be fixed by any software/firmware update that I've ever heard of.
If what I suggest seems to be true, airplane mode will be your friend. Or at least turn off data while not using it.
Good luck!
I've had my Redmi Note 2 since August or September of last year. When I initially received it through GearBest, battery life was horrendous and the phone was hot all the time. I frantically searched for how to install custom ROMs, and after many hours of hopping around sites, I figured it out and fixed the issue. Battery life was quite good from then on out, and I rarely finished a day with less than 70% battery and an hour or two of SOT. I still got the impression that my battery life wasn't as good as the people who were getting 4+ hours of SOT, but I couldn't really complain since I'm not a super heavy user. Changing from MIUI to AOSP and CM based ROMs didn't seem to have a big impact.
Fast forward to January and I suddenly started ending days with 50% battery with minimal usage while on one of the first CM ROMs made by Bule. It seemed to happen all at once. This was around the same time as I got my Mi Band 1s, but after installing Gsam battery, trying different ROMs, and going a few days without the MiFit app installed, I determined that it wasn't anything related to having the new device connected to the phone. Nothing seemed to suggest that any apps I had installed were sucking more battery than they used to.
Then, about a month ago, my battery life took another dip and I found myself finishing days with 20-40% battery left with only an hour of SOT. I'm often at 60-70% as I leave my university in the early afternoon, and I hardly use my device at all during class.
Currently, I seem to lose about 1% of battery per minute of SOT. Standby isn't too bad, but definitely not as good as it used to be. Having problems across the board suggests to me that my battery may be faulty and dying slowly. I purchased a new battery, but it hasn't arrived yet.
If the new battery is clearly better than the original, then the problem will be solved. But if it seems to be about the same, then it's possible that it isn't the battery's fault after all and I'm doing something stupid to drain my battery. Update: New battery does not seem to be helping.
Does anyone have any suggestions? I've tried to use the Redmi Note Tool app (making sure to use the setting for CM), but I've seen absolutely zero change in battery life. I've changed ROMs at least twice since the problems arose to no avail. WiFi and Bluetooth are on all of the time, but articles I've read seem to suggest that these things are rarely to blame for poor battery life. GPS is used occasionally but isn't on consistently. Screen brightness is set to Auto with the bar below half.
Update: For those who have helped and those who may have similar issues, I believe I've found the solution. After completely re-installing the original China ROM with Fastboot and the MiFlash tool, the issue seems to be solved. I really have no idea what the issue was, but it was clearly something pretty fundamental that wasn't getting reset with TWRP wipes and ROM swaps.
Just in case someone wants it, here are the guides I followed:
ROM: http://en.miui.com/a-234.html
TWRP: https://felixsenada.wordpress.com/2...ng-twrp-recovery-and-root-redmi-note-23prime/
If you have twrp I suggest you to take a backup of the current rom and try messing around.
1. Try 3C Toolbox Pro or any free app tha allows you to change the permissions/freeze etc running apps. Change the apps tha start with the device. Freeze some unnesessary just for the sake of testing.
2. How many apps are you using? Not the ones you have installed and sittings, but actually using everyday. Did you install any in the same period you noticed things go sideways? 1% per minute is not a good sign.
3. Install wakelock detector and monitor what is draining your battery over time.
4. Clear cache/davlik through twrp and wait the phone to recreate the files. Maybe thats just it.

Thank you for your response.
I will look into 1 and 3. As far as apps go, I have a total of 51 apps installed (in the drawer including all the pre-loaded apps), but I only use an absolute maximum of about 12 of them, and on an average day, I only use a handful of those. The only things I can remember installing around the same time I first started having issues were Google Fit and Mi Fit. However, neither showed up in Gsam as suspects, and after changing ROMs on at least one occasion, I didn't reinstall them just to make sure. I still had the same issues with or without them.
4 is something I do regularly whenever I change ROMs, so I don't think that's the solution.
Just to make absolutely sure that I hadn't already overlooked something, this morning I turned off auto brightness and location. It's still too early to tell, but I think turning off auto brightness may have helped.
Nice. Lets see how this goes.
charge at 100 % with screen off flash latest china stable via fastboot(not recovery) use phone for 3 days like this(i now it's a pain but its worth trust me) .
flash twrp via fastboot than flash xiaomi.eu 7.3.2.0 and super su .
4-5 hours SOT assured (assuming your battery doesnt have problems)

I've had my Redmi Note 2 since August or September of last year. When I initially received it through GearBest, battery life was horrendous and the phone was hot all the time. I frantically searched for how to install custom ROMs, and after many hours of hopping around sites, I figured it out and fixed the issue. Battery life was quite good from then on out, and I rarely finished a day with less than 70% battery and an hour or two of SOT. I still got the impression that my battery life wasn't as good as the people who were getting 4+ hours of SOT, but I couldn't really complain since I'm not a super heavy user. Changing from MIUI to AOSP and CM based ROMs didn't seem to have a big impact.
Fast forward to January and I suddenly started ending days with 50% battery with minimal usage while on one of the first CM ROMs made by Bule. It seemed to happen all at once. This was around the same time as I got my Mi Band 1s, but after installing Gsam battery, trying different ROMs, and going a few days without the MiFit app installed, I determined that it wasn't anything related to having the new device connected to the phone. Nothing seemed to suggest that any apps I had installed were sucking more battery than they used to.

Update: I've been traveling for the past two weeks or so, so I haven't been able to respond.
I flashed the latest Xiaomi.eu build before leaving on the trip, but this did not help noticeably, so I can pretty definitively say that it is not an issue with any of the ROMs I've been using. Although it was never really suspected, I suppose this also confirms that it doesn't have to do with my house/work being in a bad spot for cell/WiFi or something odd like that.
Having returned to find my new battery waiting, it seems the battery is not the issue as I have been getting the same behavior today as usual (only a bit over an hour into the day from 100% charge and I'm already below 90% with 8 minutes of SOT).
Unfortunately, I haven't tried any wakelock detectors or other monitors yet since I wouldn't have had time to figure it out while I was away. I can look into this now, but my instinct says that I probably won't find anything that GSam hasn't been reporting anyway.
Finally, I did manage to get 2 hours SOT out of it one day (with lots of GPS usage as well!) and about an hour and a half yesterday, so I know that it isn't incapable of heavier usage; it just seems that it drains more slowly at random on certain days. The only other thing I've noticed is that, when the battery is draining more slowly, the 'Kernel (Android OS)' seen in the GSam screenshot on the original post drops to being about on par with 'Android System'. I don't really know what this would indicate, but maybe someone else could propose an educated theory.

Thanks for the advice, but I have some clarifying questions to make sure I don't do anything stupid that could brick my phone (an excuse to buy a Mi 5 would be great and all, but I really ought to do my best to make this phone work since it can do everything I need just fine).
Can any ROM be flashed via fastboot, or is there a specific one I need to download? I downloaded the china ROM from here: http://en.miui.com/download-274.html#396
Which method of fastboot flashing should I use? When I originally installed TWRP to get the original ROM off of my device, I was confused and bounced around many different sites trying to get ADB and VCOM drivers working, but I see now that there is a simple MiPhone fastboot tool that seems like it would work fine: http://en.miui.com/thread-145555-1-1.html
Do I need to do any wiping first? Normally I wipe via TWRP, but will the fastboot flash automatically get rid of all the data? Will TWRP be wiped as well since you reference re-installing it later?
Thanks for your help!

download fastboot rom here
extract it with 7zip , WinZip,Winrar (your choice)it's an archive basically since you have installed twrp that means fastboot drivers are already installed
now make sure u have twrp 3.0.2 by jemini since it's modded to not let stock rom overwrite twrp
so the recovery.img by jemini place it in images folder that you've extracted replacing stock mi recovery so you hit two birds with one stone .
than click the .bat file flash all
EVERYTHING must be erased EVEN INTERNAL MEMORY
