[Q] Battery is not recognized - Defy Q&A, Help & Troubleshooting

Hi all,
Nasty problem with my 1 month old Motorola Defy+ (MB526)
Last weekend I installed ICS9 from Quarx (20120318 build). I did this using 2ndinit CWM. Made an android backup of my stock setup, I did this over my stock SBF 4.5.1.-134_DFP-74. Used the gapps.zip and battery fix.
The system worked pretty well, but time by time it was unstable. When turned off, it had lots of difficulty to boot up again, lots of reboots and 2-3 battery pulls.
I was planning to flash another ROM when I had the time. Yesterday it worked well, started fully loaded, used it as MP3 for long time, when I went to sleep it was 48% (the accu).
This morning, I stepped in car and phone turned out to be dead. Connected it to my car charger, and it came back to life. However, immediate reboot etc. So I decided to (while driving) put back my stock nandroid backup.
It all turned out well. Stock ROM booted but gave the notice (translation from dutch): "Battery of your device is invalid and cannot be charged. Replace the battery with a battery from your Motorola"
hmm, tried it with my USB cable at the office, and now at home again with the normal charger..
What happened? Any ideas on how to solve this?
The complication is that now my device is rooted and has 2ndinit starter, warranty is more difficult.

Solution: red lens battery fix
I’m not sure it’s exactly the same issue, but my Defy+ totally refuses to charge with Quarx CM9 build 20120318 + CM9 kernel from [1].
Unfortunately I noticed only once the battery was dead empty.
I couldn’t even get it to boot with the USB charger pluged in, and the only way I could get it to boot again was to charge my battery pack in friend’s Defy.
Then I applied the « Battery fix for red lens » provided here [1] which kind of fixed the problem. Now the battery charges again, but it won’t charge over 80/85%.
I had done a « Clean battery stats » from the boot menu after installing CM9 before this whole story, so I don’t know if it had any effect.
If anyone knows better please let me know!
The instability you noticed may be due to the Android debug bug… in CM9 builds. You have to leave Android USB debug (from System params->Debug features, translated from french on, otherwise it will lag like hell most of the time and drain the battery due to the init process eating up the CPU.

Hi, I installed the battery fix immediatly after flashing the Quarx ROM, so that should not be the problem.
In the meanwhile I have been trying some things with the battery calibration software. That one flawlessy sees that my battery is 100% charged (i did that using the mcguyver method). But, resetting the calibration file on the phone won't help.
In the meantime I have been able to delete all traces (2ndinit boot, titanium backup and unrooted my phone) so I am considering to RMA the phone, no matter the fact how long that is going to take..
Unless, someone here has a last excellent advice..

Great! You have just fried your battery (like a few others who tried going McGyver). Get a new battery now and don't use the McGyver method again

From what do you draw this conclusion?
The battery showed more problems BEFORE i used the mcguyver method than after. When the problems started I never even heard of the method. I used it to regain life in my mobile (which I am using atm) and charge the battery, which was succesfull. Charger over USB does not work (because battery is not recognized), but that problem occured before the mcguyver.
So until now for me it did not cause the problem, but it helped me to be able to use my phone again, much better than before. I performed the method very accurately and I am 100% sure it did not make contact with connectors it should not connect to.

Well now that your phone is alive, then go to stock and reclaim warranty! Do RMA.!

Yes I will, restored everything to stock and deleted trace from MicroSD.
But, I am still annoyed by the fact that my phone will be gone for 3-4 weeks

I understand that bro!! Even my phone was away for couple of weeks recently! Just pray they don't flash the latest SBF(BL7_ as they did in mine!

Does flashing a full sbf not work either? like this http://forum.xda-developers.com/showthread.php?t=1574651

Hi, this morning everything changed again, I decided to give it one more try with the latest Quarx CM9 nightly (20120330), wiped data, flashed nightly.zip, gapps and kernel but waited with the battery. After that I wiped cache, dalvik and battery stats.
Reboot and battery seems alive? very strange. But I don't want the kind of buggy CM9 builds anymore, so decided to put back my 2 hours old nandroid backup, using Restore.
Strangly, battery problem was back again. ****! Than just for fun I did data/cache/dalvik/battery stats wipe on stock, and that did not help either.
Now I am back on CM9 again, but thats running O.K. (battery is working!) but not stable enough for me. CM7 (cannot remember which build) gave the problem as well.
With the latter in mind I think (and thus agree with you) flashing a fresh SBF will probably solve the problem, but I am not 100% sure. I want to be able to put back my stock setup for possible RMA. My stock is 4.5.1.-134_DFP-74 and I cannot find that one on internet. And I cannot put it back to stock otherwise right?
The one Pranks gave you in your post (4.5.1-134_DFP-1321) is that a deblurred one? Because when I put a new one, I would like it to be a deblurred. I hate all the bloatware.

I have no idea, but I think he said it was from his own defy so I am guessing it the complete original blurred thing.

I redid the cm9 flashing too and now at least it is telling me the battery is charging. But it stays stuck at a big battery icon and a red led is on.
Will see if it goes past that screen with a bit more juice.
---------- Post added at 02:06 PM ---------- Previous post was at 01:57 PM ----------
Yessss, it started up!

All is fixed. I flashed the proposed stock non-fixed SBF and now running stock 2.3.6 without any battery problems. Excellent The SBF is rootable.
I removed BLUR by editing build.prop as proposed somewhere on this forum. you have to perform full wipe after editing the build.prop) I am very happy with me new DEBLURRED stock. Titanium can remove other bloatwhere like "cardiotrainer".

Nothing works as it should...

I can't begin to describe how frustrated this phone has made me. I am not an Android "n00b" by any stretch. I have had 4 different Android phones, have flashed at LEAST 100 different roms, made complete rom themes, and even glued together one of the first complete Gingerbread roms to flash from recovery for the Motorola Droid (not from source, but first posted rom with working camera, Gapps, and all from standard recovery - not nandroid). With that being said, this phone is next to impossible for me to use. I've lost track of all of the problems I have had with this thing. Everything from CWM not being able to restore any backups, horrible battery life, boot loops galore, the phone freezing anytime it is plugged into the computer or wall (not the car charger, oddly enough), boot loops, tried the Yellow Clockwork (and everything failed that could on that), flashing roms that would work great until you reboot the first time, and so on and so forth. WHEN the phone works, it's great. However, that is starting to become quite rare. Most recently I have been stuck on trying to get either Evil Fascinate to work or MIUIWiz with no luck for either. EF works great...until I restore my apps. Once I reboot, it's all over. EVERYTHING force closes and it becomes completely unusable. Doesn't matter what kernel I use, it always happens. And this is now happening with both 3.5.1 and 3.6.0. Plus I could just watch the battery life plummet as I was using it. I even tried the EC01 radio with it, as it was suggested that might be better. So, I decided to try MIUIWiz. Followed the directions perfectly. Wiped everything, flashed a JT Kernel from 4/15, flashed rom, and...guess what? Boot loops. I am on ClockworkMod 3.0.2.7. I am familiar with how to wipe data/cache/dalvik. There were no voltage settings to wipe. I did check to see if Voodoo was enabled before booting. I just don't know what else to do. This isn't exactly rocket science and I really feel it can't just be user error at this stage with all of the different issues I have ran across. I'm pretty much at the stage that I am gonna return it to stock and sell it, but would really like to enjoy it for a little while longer... Thoughts?
Just for laughs, I downloaded Community Rom 1.3. Was on EF 3.6 (with nothing restored, just signed into Google). Rebooted to Recovery, wiped everything, installed Comm Rom and never got past the Samsung screen. *sigh* Seems odds since they are based on the same base, but yea, that's how it's been going for me.
I think since you are so god awfully experienced that you are looking over something that probably seems useless to you, ive NEVER experienced any of your problems and I can tell you its not the phone.. I would read up about your specific problems or ask a specific question and you might get the help you need.
Edit:Bootloops are user error nearly every time. Unless you have a corrupt download or something.

As much as your sarcasm warrants a rude response, I'll choose not to stoop to that level. The point of the post was that there is not a "specific" problem. Hence the title, "Nothing works as it should..." Not every phone is the same, and just because you have experienced any of these problems does not determine whether my issues are phone related or not. Battery life issues are very common place, which is evident in many threads. The phone lagging when plugged in is most CERTAINLY a phone issue and has nothing to do with rom flashing. It appears this is a firmware issue and is not likely to be fixed at all. Also, I pointed out the steps used to flash the rom, which are posted in the thread, and still have problems with boot loops. So, I guess every rom I download is corrupted? Even though on different networks and computers? That's some luck I have...
Are you referring to "download" mode when you said yellow cwm? If so then maybe reinstall the samsung drivers and give it a clean flash including the pit with voodoo disabled. If you have bad problems like you are having that fixes anything I encounter.
Edit: if you use odin, try heimdall

The newest imnuts kernel installs a yellow CWM, and nothing worked right at all on that. Every verification failed. SO I ODINed back to stock and retried everything anew. Anytime I restore my apps with Titanium, the next reboot fails. I even just went back to stock again, flashed CWM Red 3.0.2.8ti and the stock kernel with recovery fix, restored apps again and rebooted and it did the same thing. I didn't have any issues with Titanium restoring stuff before, having successfully used it on EF 3.5.1 and ComRom 1.3 but not those don't work for me either anymore. I've tried restoring just the apps with no data and that doesn't seem to make a difference either.
EDIT - It must have something to do with Titanium. Gonna try an older version and see if that works. It looks like they updated it recently and maybe it is just not playing nice with anything for my phone.
When you restore try not restoring system data, that is check the box for user applications only. That might be the issue.
yea, I'm going to say Ti backup is the problem because you mention ti every time you have a problem. personally I don't use ti cause its never played nice for me, but did you try manually reinstalling a couple of apps reboot and see if the same problem happened? that would really narrow it down almost completely to ti.
Fascinate 2.2 1.2GHz(uv)
download the imnuts peanut butta jellytime kernel of choice and put it on your sdcard. Odin back to the stock rom of your choice (i recommended eb01 as other odin packages cause bad music quality.), and let the phone boot up.
Next, pull the battery and go back into download mode. Odin one of times_infinity's cwm packages. Then replace the battery and boot straight into CWM. Wipe data, cache, and dalbik and then flash community rom 1.3. IMMEDIATELY AFTER (meaning in the same cwm as when you flashed comm rom 1.3) flash the imnuts kernel that you put on your sdcard. Phone should boot up fine and be fully functional. As mentioned earlier by someone, dont restore system data with titanium backup.
It's not just the system data that is causing issues, as I have tried it both ways, and of course, only restoring system data that is labeled green when attempting to do so. And, it did work previously on EF 3.5.1 but no longer does. I'll give it another shot using thefunkbot's directions. Still confused as to why EF is the only rom that boots normally.
Alright, so that did get Com Rom running. I had actually tried that method before, but it took so long on the Samsung screen that I was sure that it was froze. I just let it go this time, and after about 5 minutes it finally started. None on the other roms I tried took that long, but whatever works...
that's probably due to voodoo, which takes about that time to install/initiate.
Yea, you can hear the creepy robot lady telling you what's going on, but it took a couple of minutes after that even. Also, I skipped Titanium and restored the apps manually. Some were from my SD card and some from the Market, and only about half of them worked after rebooting. Meh
Flash com rom, then flash the otb kernel. Comrom will boot and you will enjoy your phone.
I got Com Rom to boot, but alot of the apps won't reinstall without force closing after rebooting. Not being able to use Titanium is a major PITA to me. But it's not just Com Rom, it's EF, and even the stock rom. Just never had an issue with it before now. But even installing apps through the Market or from the SD card also created issues, so I dunno what is going on.
If you're getting a **** ton of FCs, try fixing permissions via Terminal Emulator. Run 'fxpms' and it *should* solve some FC issues. Also, the phone generally takes much longer than a couple minutes to boot up after doing a full wipe, because the dalvik cache has to be rebuilt. Guarantee that if you had just left the phone alone the first time it was stuck on the Samsung screen, it would've booted just fine.
There are many guides that should help if you run into problems. First odin back to stock update to get new modem (doesn't have to be the newest but might a well), use the pit as well. Second odin cwm. Then flash kern and rom with a voodoo conversion if desired.
At first don't restore any backups. Don't use any themes. Or make any other changes until you see how out runs. Also don't play with the under volting until you've used it a while.
After running it awhile "stock" a it were then start making your changes one by one. This way at least you will know what its causing the trouble.
That happened to me as well when flashed com rom. I took 3 batt pulls before I just let it go to find it was working all along just took its sweet time on first boot. Was not voodoo here. I also agree with your charger problem, but for me its reversed, only happens on the car charger. And I hate to say it but no froyo rom, stock or otherwise, plays nice with my fascinate. I get all kinds of weird bugs. And battery life got worse. Since I have come to the realization that no fascinate aosp or cm rom will ever have bluetooth headset support, I finally threw in the towel and spent an hour on the phone with verizon to get an upgrade. Sad but after all this time it was time to give up.

Wiping Davlik causes unusually long boot times on Froyo ROMs on the Fascinate. If you just wait it out (if it's more than 15 minutes, though, something's wrong) you should be golden. By the way, PBJ 5/23 is literally a non-starter, so I would suggest nemesis2all's OTB kernel until imnuts updates.
Another Fascinating post by my XDA app...
Thanks for all the help and advice everyone. After trying five different roms, I finally found one that works for me. Blackhole. I set it up just like the others, the difference being that Titanium and everything else works. Still have to test battery life, but just having all my apps and no force closes or boot loops is enough for now...

Blackhole 4.4? Or an earlier version? I miss SonOfSkywalker's work since he added the Thunderbolt to his arsenal (he also devs for the Vibrant)
Another Fascinating post by my XDA app...
4.4. Haven't had any issues with it so far. Battery life is probably not the best so far it seems, however I don't even care at this stage as long as everything works. I also have not run it down and reset the battery or played with many settings yet so not ready to say it is the rom or anything of the sort. Everyone has their deal breakers with their phone, and not having Titanium work is one of my biggest things. I love that app. I didn't donate for it to not use it, you know? I'm a themer, and I have a lot of themed apps saved with it that makes the Market pretty much useless to reinstall stuff for me. Plus it is an easy way to uninstall system apps without screwing anything else up.

Crashes after 5 minutes and IMEI invalid

Hi!
I've been using cooked ROMS from xdadevelopers for a long time, but since a few weeks (using the last [ROM GNEXUS PORT] JRO03L 4.1.1 RC) my Galaxy started to get crashes every 5 minutes, and after each crash, the battery dropped from 99% to 2%. If I had the phone off for a long time, it recovered part of the battery, but it would never switch on again until I plug it in. At the same time I got the message of IMEI invalid.
Yesterday I changed the ROM to the one of SLIM BEAN 2.5, and I got the same problem.
Does anyone has the same issue? Is it a problem of battery or did I do something wrong in the process?
Thank you very much! Any advice would be highly appreciated, as right now I have no phone :-s
Do you have an IMEI backup? I would recommend going back to GB, restore the IMEI, flash CM9, flash whatever you like.

Thanks for your answer!!! I have backup of the EMS. I've never restored it, but I'll look for the info in the forum.
I'll follow your advice as right now is the only thing I didn't try.
I'll let you know :-s

I meant EFS
Battery may need replacing.. I had exactly the same symptoms about a month ago on cm10 and devil kernel. After trying everything from factory resets, new roms, different kernels and numerous battery calibrations, it was, in the end, a new battery and another complete wipe, going all the way back to froyo via gingerbread and wiping absolutely everything (before reinstalling cm10), that solved my problems. You can pick up a new battery online for about £7.00.
I think a dodgy rom download was the reason of all the problems, of the wrong imei and, maybe, the kernel voltages were corrupt which caused the problems with the battery stats going all over the place and the phone switching off. The constantly having to plug the charger in to get the phone to boot up again was imo what overcharged and ruined the battery.

[Q] Stuck at CyanogenMod animation.

I searched but could not find a similar thread.
On my Defy (green lens), I was running 10.1 July build.
I got a new battery and used it one day. When it was low, I turned off the phone and put my old battery and rebooted. Everything was fine.
Since I have also a battery charger, I charged my new battery through it and when the old one was draining, I swapped it with the new one again and turned on the phone.
Ever since, the phone is stuck on the CM animation.
I would like to know what is the best way forward for me.

Wipe your /data and /cache partitions and reboot. If that doesn't work, wipe everything and reflash the ROM. If you're worried about your data you can make a backup, before wiping, and then restore your apps+data with Titanium backup from the TWRP backup. I wouldn't restore system apps/settings.
Recovery
I did a stock recovery. Somehow it did not fix my problem. Then I did a custom recovery and wiped data, cache and dalvik.
As a result, all my apps were wiped out (not a problem) and perhaps some of my data as well.
However the result was a much better 4.1.2 experience.
Everything works fast - no lags whatsoever.
Only problem is that the icons for People and Messaging in the Dock disappear after some time. This has happened more than 3 times in the last 24 hours.

ah well.......my 8013 bricked forever

I had Gnabo v8 running fine of my 8013. Then the battery started draining fast and would not recharge. I had the rom, SU, remove phone, and wifi fix all on my ext SDcard.
Wiped and reflashed all using Philztouch recovery.. Got back to KitKat but no wifi. Flashed the wifi fix again. Now unable to do anything. Can't get to recovery. Battery at zero, so can't use USB.
Oh well..........I am in the market for a new tablet. I might try the Note 12 pro, but not unless they release an official Lollipop version.
Try replacing the battery.
I've just replaced my N8000 battery & it looks like new now
There is always a way back. If you have odin you should be able to reflash stock with it.
If you are looking for a new battery take a look at

A hand full of people have been saying this is an awesome deal!
All fixed
Once I got my charger/cable problem fixed, I charged, reflashed Gnabo, SU, boot, phonefix, and wifi fix.
Back in business. Ordered a backup charging cable, since I know the one I have must be positioned just right
in order to maintain contact at a break in the wire.
Thanks for all the help/comments/advice.

Nexus 4 turning off when unplugged from charger

Hey guys, i have been owning this piece of great phone for almost two years. But it never gave me a big issue.
Nevertheless, few months back i flashed cm12 and it worked great too.. I had been using it gracefully till i decided to update to cm12.1. So i decided to update, but the update always crashed google play services. The update did not happen automatically so i had to flash the zip through custom recovery (already installed) by myself.
I could not come out of that so i went ahead and did a full wipe and flashed cm12.1 along with gapps. Since then when i am unplugged it goes only to about few minutes (on battery) and shuts down. So, i now decided that this piece of update is buggy and did a full wipe and reflashed the original cm12 zip and gapps which i had placed in the first place. But, to my horror even this time it could not go past the bootscreen even and turns itself off when its about to start up. (Battery is full charged, did an overnight charge as well).One very unusual thing i noticed that almost all the the time i try to power it on it showed me "optimising app X of Y" which is weird. This kinda happens only on first boot.
But if i keep my phone plugged in to ac charge then it works fine.. but only last night it hanged and turned off even on charge. So there i decided that the cm thing is not for me. So i followed this tutorial and flashed the stock 5.1.1 rom (did a full wipe, tried oem lock and re unlocked and proceeded too).
But, i find the same problem same issue!! When unplugged my device, it just turns off even on full battery charge.
Can someone explain me the technical parts of the issue and what has gone wrong and how it can be fixed?
Please, Thanks
EDIT
Last time i locked - unlocked bootloader and proceeded with a fresh factory image flash, the device turned off on boot even when plugged in to my mac and it's hot on the back side
Sounds to me like there''s something physically wrong with the phone, probably the battery. Time for a new one anyway. Lithium batteries degrade with use. After ~500 charge cycles it'll have lost upwards of 20% of its original capacity and might show other signs of wearing out like inconsistent voltages. After 2 years of use, you'll be well beyond 500 cycles. A new battery off eBay is pretty cheap, and some sellers include the needed tools.Go to ifixit.com for a tear-down guide. A hair drier can help soften up the adhesive. The fact that it turned off despite being plugged in to your computer also points to the battery being toast - the USB amperage from a computer is less than the typical wall charger.
If it's not the battery giving you woes, I don't know what it could be.
And FYI, the whole "optimizing app" thing is the OS rebuilding the cache. When you flash your GAPPs package or a zipped Titanium backup it has to build the cache for the new apps. Same as when you do the "wipe Dalvik and cache" part of standard flashing procedure to avoid conflicts. In order for apps to load quickly, Android stores a lot of the necessary data in cache, so when you clear it or have new apps, it has to rebuild the cache. On Lollipop this takes a loooooooong time because of the way ART works.

How can i be completely sure that it's the battery which needs to be replaced? The battery shows charge. When i plug in and boot up it shows enough battery power left.
Currently, without external power it does not go past the google screen on boot. When i plug in power while device is off, the battery meter shows just a little depletion from full charge. When turned on, battery level is 82 %
After all , all this hardware mess up can be the consequence of a bad cm flash ?
the whole "optimizing app" thing is the OS rebuilding the cache.

I know this. Earlier it was happening on each boot. Now it seemed to be stopped.
By any chance did you have your phone charging while flashing and booting up your ROM?

Exactly same problem is started with my Nexus 4 ... I really wonder, what is causing this. Meanwhile, have it sorted for you ? is that hardware (Battery) issue?

I too am facing kinda similar problem.
It first started on my stock Lollipop 5.1.1. I had kept it on charge and when I removed it, it got switched off. Thinking that it might be just another of the multitude of bugs in Lollipop, since I already had lots of problems with it, I decided to flash CM 12.1 Stable on it.
Unlocked bootloader, flashed TWRP recovery, created a backup (using TWRP), wiped data, cache, dalvik and started installing CM 12.1. Now comes the problem, I selected 'restart system' and it did restart and CyanogenMod logo was displayed for few minutes before the phone crashed. I switched it on again normally and the Google logo got displayed, and then again phone got off just after the Google logo. I tried flashing again by same procedure, but this time not even the Cyanogen logo was displayed. The Google logo got displayed and the went off.
Then I decided to restore the backup. Restored it but it still had the same problem at the startup Google logo.
Now I have managed to install CM 12.1, which works fine unless I don't open certain apps. When I open certain apps like Phone or Clock (those are some I have tried yet), it crashes the system.
This maybe a hardware or software problem, but pretty sure it isn't battery problem, coz it retains good charge when I switch it back on after crash.

Since you already unlocked the bootloader, and therefore already wiped everything, you could try flashing a factory image.
I also got the same problem. I thought this is battery problem, so I replaced the battery but problem still there. I thought this is problem of lollipop, never installed CM or anything. It is always running stock android. After that I even downgrade to Kitkat stock version still it is not working. One more thing I noticed is If I don't unlock the device than it will be powered on, but as soon as I unlock it and if it is not plugged in to charger it will be switched off. Any suggestion what should I do?
I have the same thing for several month now.
Always thought it is the dying battery.

Just tried flashing Lollipop 5.1.1 (LMY48I) factory image. The same problem still exists. Faced few weird problems on running the first time. Following scenarios explains it exactly...
Not On Charge: Crashes after startup Google logo
Connected to Laptop (USB Charge): Crashes a few minutess after entering "Optimizing apps" screen
On Charger (AC): Completed the install (optimizing apps and setup) without problems
Now I can access the home screen and menu without problems. But when I start any app, phone will go off. Not just apps, at times even when the recent apps menu is opened.

When you flashed the factory image did you do it via fastboot or by flashing a zip file. If you used the zip file I would suggest you do it with fastboot.

By "flashing zip" you mean using "fastboot update" command? ...If so, nope I didnt. I extracted all compressed files and then flashed each of the img's using fastboot. Flashed a total of 6 img files.

I m too facing the similar issues. Phone is getting turned off suddenly when not charging, on charging it is working fine. i have done factory reset and also done factory image reset to 5.1.0. i m still facing the same issues. I don't think so it is related to battery. if anyone have the solution then please let me know.

Try the very basic flash technique by double clicking the flash-all.bat. It's not the same as flashing the imgs one by one.
Battery is the issue. Get it changed. I also faced same problem, and visited LG service center and they changed the battery. Phone working fine now.

Ok so Battery was the problem!! Got it changed, phone working fine now. Thanx all!
Ok guys i confirm that this is a battery issue. I took it to the service center and the guy temporarily replaced battery to show me issue solved... But... there i saw another issue due to which i did not buy the battery. I saw half the touchscreen not working (including the navigation buttons ). The guy at the center told its a h/w issue and i would have to spend 7K on it so i left my phone dead for now. The Question is ... can this be a s/w issue.. or result of bad flash which can solve on reflashing ??
same problem with my nexus ,but one thing i noticed that the phone does not power off while in recovery...Any idea??
