[Q] MyTouch 4G boot loop - myTouch 4G Q&A, Help & Troubleshooting

hi
ill been searching for weeks on the internet and here and i cannot find an answer to what is really causing the boot loop problem when i connect the charger or disconnect the charger.
to get the phone to work again i have to do the twist fix to get it to boot but as soon i connect the charger it restart it self and bootloop i have to twist again to boot, then when i disconnect the charger the same thing.
my question is do anyone ever find out what is causing this or where on the motherboard lies the problem?im assuming is probably close to the charging port. anyone have an idea where exactly the problem is?sorry if this been answered before but honestly i did not find it.
i know is an old phone but i like it is a good backup phone.thanks for taking the time to read this...

anyone?

thanks for answering well im not 100% what recovery version is on i factory reset the phone then rooted unlock with gfree and if i remember well i use rom manager to install the recovery.
the rom im running now is Android_Revolution_HD-Glacier_7.0.4
and my emmc chip is SEM04G

Switch roms. Try out cyanogen 7 nightly.
If it still bootloops there then its a hardware issue

well i did install cm7 nightly the latest and still when i connect the charger it reboot and bootloops i still have to do the twist fix to boot completly
i guess is hardware problem and im assuming is around the charging port because with the twist fix thats where most of the pressure is put on.
anyone knows exactly where it is so i can do a permanent fix and not twisting the phone every time to boot, i know it works now but for how long before something get damage inside by doing this.any help will be appreciated or i might have to give up on this phone.
i know for sure the emmc chip is fine because a few days ago i flash stock rom successfully. . thanks everyone

Ive never actually heard of that problem but it might be a loose flax cable that signals something and causes it to bootloop.
Do a logcat and then.show us the output.
Also instead of saying thanks press the thanks button.

Saranhai is right. It sounds like a kernel issue. If you give us more info we can recommend kernels that you can flash.
sorry guys
rooted? yes

Ok. MIUI is an alteration of AOSP. So, an AOSP compatible kernel is what you would want. However, LanternsLight puts out good MIUI ROMs. Unless its a known issue, I doubt its the ROM. Did you format your system partition before flashing?
Edit: Just spent a few minutes reading through the thread. No one else has reported this as far as I can tell. If you didn't format /system before you flashed, reflash using the instructions in the OP of the thread in the dev section. If you did, wipe cache and dalvik cache and reflash. If neither of those works, try TDJ's AOSP kernel, but there is nothing wrong with the Tiamat kernel, so I doubt that's it.
OK update i dont have any idea why this isnt working but i cleared the sd card,ran the rom install again followed the directions completely and my hotspot and wifi will bootloop my phone im at a loss of swear words already. should i take a hammer to it or not
Did you try a fresh download?
yes as stated i completely cleaned the sd card and redownloaded multiple roms and none will allow me to use wifi or hotspot the hotspot will error and the wifi will bootloop every single time
What Roms did you try?
what you can find in the recent rom section i tried i think it has to do with the phone or something im lost im frustrated im gonna flip out and smash this phone soon
Well, if you'be tried multiple ROMs with different kernels and did FULL wipes between them all, its probably hardware. I can't think of anything else it would be.
well all i did was change sd cards and thats it no more wifi and hotspot.....should i partition the sdcard i do remember seeing that in recovery does that affect the wifi n hotspot? if so what should it be partitioned at
Eeerm, partitioning the sd card is for moving apps over to external storage the pre-froyo way. It has nothing to do with hotspot functions. So your hotspot worked before, but crapped out when you changed as cards? That's really weird...
Does anyone else have any insight into this, because I'm at a loss?
Anyone out there?????? ANYONE
Try flashing the stock 2.2.1 or 2.3.4 rooted. Try if that works. If not, I too am at a loss. Maybe Jack_R1 is around lol

have you tried flashing the froyo pd15img to unroot and see if the problem persists? if not then i would do so and then report back... if the problem is still there then it seems to be a hw problem... if it is gone then it will be easy to reroot and be back in the game! just a little fyi though, if you want help then next time i would recommend providing us all the information! bootloader version, root method, rom, kernel, etc, etc, etc... you will more than likely get a more informed response and it shows that you actually put forth a bit of effort in helping us help you, rather than being the guy in my signature video! and as for your comment of this is the last day you are going to try to fix the phone, well it is your money that was spent on it, so by all means nuke the damn thing! but dont get angry cause we cant fix your device, we did nothing to it or you... take it to the store and let them mess with it or pay the deductible and get a new one... good luck on any note!

Bricked Galaxy Note! Please Help

Hey guys, I think i may have bricked my SGN.
I rooted via adb and then flashed the abyss kernel followed by stunner ics rom. But when i restarted through CWM the phone never restarted and now it won't even turn on. No download mode either and i've tried every possible trick including the wall outlet.
Phone won't turn on at all. Is this considered hard bricked and has anyone found a solution to this. Will a USB jig work on this.
Also, the stunner ics 4.5 beta showed successfull at CWM so i'm not sure what happened. Battery was fully charged too.
Try taking out the battery for a few minutes, put it back again and try entering download mode again.
What's sky ics rom?

You didnt follow the instructions ti install the rom so you now have a brick
Try pluggingn it top the pc , if you hear some noises on the pc then your noté is alive

Well, did you try a USB-jig to force your Note into Download-Mode?
Than you should be able to flash a stock and start over again.
Did you let your Note do the first startup at his own, I've read that the first start may took a bit longer and shouldn't be interrupted?

Well, i was in CWM and then installed the rom then pressed restart phone on CWM menu. Went downstairs and when I came back it didn't turn on.
if it doesn't turn on at all is it a hard brick?
I ordered a usb jig from amazon for $7.00 and it will arrive tomorrow, I heard the usb jig only works on soft bricked phones though and since mines won't even turn on will there be any chance at all of it working?
Hey guys I just realized what went wrong. I download the N7000 Galaxy note roms and kernels instead of the i717 (ATT) versions. Stupid me!

Just put the battery in then do following.
1. hold vol down+home+power for 15 seconds...
2. release then press volume up...
Note: Don't worry about seeing anything on the screen or any keys light
it will be blank this is because bootloader is incorrect
3. open odin you should see comxx in listed flash the original bootloader back
into phone this will/should resume visual display.
I have attached necessary files to resume

4. Wait 10 seconds.. Remove Battery Then Boot Back into Bootloader following steps 1&2
5. finally flash Stock Rom to resume the whole phone to original state.

thanks for the help. i read that on another post and already tried it. unfortunately its a no go.
Just came back from att center and they said that they couldn't replace it for me on the spot because they don't have the phone in stock since its a newer phone. I gotta call the number they gave me now.
Sorry you've run into such a serious issue, but in a few way it's probably quite a good thing it's a hard brick.... It's likely you would have had a raised flash counter and the fact they can't power it on there and then is a bit of a God sent.
Hope you get a replacement soon mate :thumbup:

hey, im supposed to send my phone in to them and so your saying that when i send it in they won't be able to find out that i flashed a custom rom and kernel on it?
and im not sure if its such a good thing because if it was at least soft bricked i wouldve been able to fix it most likely. thanks for your help

First of all I think It wouldnt have raised the binary counter and give triangle because you didnt use Odin to flash (Am I right?).
Second thing Thought it had given you a triangle since your phone is dead.
So they cant find that you flashed a custom kernel or the binary.

Soft button always on, also when the phone is off

Hi guys... i have a serious problem. Soft touch button is always on, although the phone is off. I supposed that was a problem of cm9 kernel. But now I have flashed cm7.2 with cm7 kernel but the problem persists ... the level of the button light was very low... but they are on...
Sent from my MB525 using XDA
I need some help
Give a try to CM7.1 that is stable... if it doesn't have this bug you may be certain that is a rom related problem... in last case this can be edited in build.props... i believe that you could disable from there, besides i don't think that is a good solution...
I have this problem with some build/nightly someday, but could not remember what one... changing rom solved...
Thank you so much. But the strange thing us that now I have flashed the froyo Nordic sbf. And the problem persist. The problem is that I have to pull out the battery everytime I shut down the phone. However I will try cm 7.1.... thanks
Sent from my MB525 using XDA
hum... them it was two diferent problems.... i believe that flashing nordic that is a stock sbf should solve both problems... but if they persist then this are beyond my simple knowledges...
good luck indeed!
Always on means always responds to presses or just the light is always on?
On... minimum level but on.....

Its really weird try flashing some other sbf for your phone and see else it might be a hardware issue.
I have exactly the same problem for months. I can't remember what caused it but it has remained so even after flashing back to official rom.
I consulted a local customer service center and they said this was a hardware issue. The motherboard has to be replaced to solve it.
Ok thank you,,, as i expect is an hardware issue,,, so i have to send away my defy to replace motherbord,,, wow, i'm very happy-.-

Just wanted to say that I got the same problem on Defy+ since rooting
(DEFYPLUS_U3_4.5.1-134_DFP-231_CEE_ROOTED_No_Signed) and installing Epsis CM9.
Don´t see why this should be hardware-related.
Update: fixed after different cm9 flash and cache clean

I though it was hardware related as even if I turn it off, remove the battery, when I just put it in the soft buttons glow but as I didn't notice how it was before the first flash I can't tell for sure but after reading this I still have a hope.
I am having this problem with my Defy. Currently I have CyanogenMod v9-20121116-Nightly-jordan and I am still suffering the problem although I have tried several flashs. Could you please explain how did you solve it?
Thank you very much!!

Guys help Battery Not charging!!!!!!!!!!!

Guys i know nemesis is banned on xda but still i need immediate help.
Guys yesterday i downloaded and flashed Nemesis V2 on my phone then it was working fine it was on stock kernal after that i put my phone on charge and went to sleep when i wake up i saw the phone has not charged a bit rather it has decreased to 17%.
I thought it is a kernel problem and flashed percy gnu#10. But then also the problem persisted rather it was worsened then i switched off the device and put it to charge and it worked well. I tried flashing stock rom via odin but the problem remains same. Guys plz help asap.
DO NOT mention the name of banned roms in xda. BTW, i think it is caused by:
1. Battery itself
2. Internal Hardware
3. Charger adapter

But you could try deleting battery stats in CWM in might help.

Look at your charging slot and charger plug.
Maybe it has dust or something in.

Nexus4, sudden signal loss

Good evening, I'm having issues with my nexus .
Days ago a friend of mine told me about the Xenon HD rom, and I decided to try it (Im a CM user).
Today, I made a backup with TWRP and flashed the rom, I tested it for a few hours and I did not liked it, so I decided to go back to the previous rom, so I restored the backup. I realized that all my applications were not installed, so then I decided to do a Factory Reset and restore the backup again, my apps were still missing.
So I decided and start from scratch, doing another factory reset and installing CM on it, I factory reset it and I realize that my phone did not have any signal!
Wifi and everything is working but iit is not receiving any signal!
Can anyone help? I even tested it with a simcard from another company and nothing!
Are there any settings that may have been moved? Some option? please help me!

Good day, I just wanted to let you guys know that the weirdest thing just happened to me.
I just came from my office and thought about going and turning on my phone, I did, and enabled airplane mode, (also turned on and off nfc) when I disabled it, my phone detected the network signal! I even received a sms, I also made a call! and thought, wow! it fixed itself up! I was literally dancing in my room and changing my simcard... (because I did all the above with a replacement chip that I have) and when I finally put my chip back, I made a call and it lost the signal again... It is now again without signal... I’m beginning to think this is a hardware problem...
Any update on this?
I've had the same problem for a few weeks now, the 3G/H signal just drops out, rebooting, airplane mode switching, returning to stock, different apn's, changing radios, replacing sims have all had no effect.
It's getting embarrassing now, seems to be such a common problem and yet no acknowledgement from Google about the issue which I believe to be deep in the settings/software and relating to the hardware in the original batch of Nexus phones.
I could arrange a return and get a replacement but I've read that even replacements have the same issue.
Apart from throwing the thing against the wall is there any other fixes out there?
If it helps I'm on 02 UK pay monthly, surrounded by cell towers, the phone is rooted and running stock 4.3
Just checking it now and I have H and 4 full blue bars - Ok update twitter.. nope, ok go to the play store..nope...
